Description

200304506 Description of the invention: [Technical field to which the invention belongs] The present invention relates to a method for electronic contact of flat products in a continuous operation electrolytic machine. The invention further relates to a device for processing the method. The present invention is preferably used in the field of electrochemical processing of printed circuit boards, circuit films, wafers, and tapes. It is suitable for continuous operation machines with soluble or insoluble electrodes in the electrolyte.

[Prior Art] For the electrochemical treatment of circuit boards, circuit films, or continuous belts, continuous operation machines with horizontal or vertical transfer of products are known. The product is supported by transfer rollers or clamps, and is continuously transferred in a horizontal or suspended manner. In order to handle the product, it must be conductively connected to an electrode of the cell current source. This connection is achieved by a contact. The other electrode of the electrolytic cell current source is connected to a common electrode. One of the electrolytic cells is composed of the electrode, the common electrode, the electrolytic cell, and the source of the electrolytic cell current. The invention is in principle used in all electrochemical processes, i.e. electroless plating, etching, anodizing or cathodic reduction. For the sake of brevity, the present invention will only describe electrochemical plating. In this process, the product becomes the cathode (ie, a cathode), and the common electrode becomes the anode (ie, the anode and the cathode hereinafter are also commonly referred to as an electrode. German Patent Document DE 1 96 33 797 A1 discloses A continuous running machine. A metal contact roller is arranged between the anodes according to the product conveying direction, wherein the contact roller is a cathode and is also responsible for continuously conveying the product. Due to the rotation of the contact roller of 3 200304506, the field is completely electrically shielded The

'And these rollers are chemically plated or coated with metal at the same time as the product. In order to continuously remove rollers that do not need to be coated with metal, the gold shoulder coating is used to remove metal. Each cathode is arranged adjacent to each roller. This is disadvantageous because the removal of the metal coating is not completely completed. There is a danger of particle formation due to the non-adherent layer or metal residue on the contact roller and the cathode for demetallization. Therefore, it is necessary to frequently interrupt production for repairing the contact wheel and replacing the cathode for removing metal coating. Furthermore, another disadvantage is that the current used for electrochemical plating must be transmitted to the rotating roller. In wet chemistries, the necessary sliding contact due to chemical corrosion causes increased wear.

German patent document DE 32 36 545 C2 provides upper and lower contact wheels for electronic contact with printed circuit boards. These contact wheels roll on the edges of the circuit board. The brush will shield the contact wheel from the electric field of the electrolytic unit. This view requires a fairly wide plated edge. Another disadvantage here is that the current of the electrochemical power mine must be supplied to the contact wheel via sliding contact. U.S. Patent No. 6,2 94,0 6 0B1 discloses a winch for electronic contact. These winches are fixed on a continuous chain belt and move in parallel with the circuit board. The electronic contact winch is driven by the contact roller "This current transmission will also cause continuous wear. In the unissued German patent document DE 100 43 815 A1, a method for electronic contact of flat products in a continuous operation machine is further disclosed. The product is contacted by a contact strip during the electrochemical treatment. This method is achieved by placing and pressing the contact strip onto the product surface. This placement of the contact 4 200304506 tape means that the product does not move relative to the contact tape. In order to avoid relative movement, two possible solutions have been proposed, one of which is to stop the conveying when the contact belt is placed on the product, or on the other hand, based on "flying saw," and the rearward conveying of the raised contact belt The principle of synchronously transferring products and contact belts. In the first case, the stepped transfer is technically easy to implement only on light products. The second case can handle heavy products. However, the disadvantage is that it requires a lot of technical effort, It is used to synchronize the contact belt with the product in the conveying direction and individual backward movements. The unissued German patent document DE 1 004 4 3 8 1 7 A 1 discloses a function that transmits current to a contact on the product. Electrodes, especially for products that have an insulating structure and are to be electrolytically treated. The contact electrode is pressed against the surface of the product by a movable device. A specific driver will be used for pressing. , Principles are implemented. SUMMARY OF THE INVENTION An object of the present invention is to provide a method and a device suitable for electronic contact between a flat product and any weight product in a continuous operation machine, without including the foregoing disadvantages. In particular, a technically easy and inexpensive implementation can be provided. Furthermore, it should include no wear when transmitting current to the contact members. This object is solved by disclosing the method that is not in item i of the scope of patent application of this patent and the device according to item 16 of the scope of patent application of this patent. [Embodiment] 5 200304506 The following invention. The following or similar components are omitted. The first contact surface is parallel to the length of the product when placed on the product line 1a and the length of the contact surface is shorter. For example, the contact extension is short. The contact surface is called a cylindrical shape. A handle 22 moves or is mechanically operated in the direction of the arrow 8 to operate a linear contact with a variety of lines. The contact is less generated, such as 1 interruption, until the most specific preferred embodiment of the present invention will be described with reference to the drawings. The same reference numbers in the drawings will be used to designate the same. Therefore, repeated descriptions of the same and similar components will be saved. Each linear contact in the figure 2b is shown in a cross-sectional view. It is on 1 and contacts the product for transmission. Electric current, which produces a conductive surface. The linear contact extends vertically to the surface of the flat of the protrusion. In the large example extending vertically to the plane of the protrusion, the linear contact will be referred to as a strip contact, extending across the product's transport path. In the length of this linear contact, it will be called a cube contact. If the linear joint (where the surface faces the product), the linear contact will contact the cube contact and the cylindrical contact system are more suitable for edges. The linear contact 20 of the carrier 21 is composed of contact rods 23 and 24. At least one bracket 12 supported by an electric travel device 28 · is installed on the opposite side of the carrier. The device 28 raises or lowers the linear contact. A travel device is in proper contact, such as above the product and below it. The relevant link will be used. This stroke height will cause the surface 27 to no longer electronically contact the surface of any product 1, a stroke height of millimeters. The electronic-mechanical contact is then placed once. A common application is two-sided treatment of products. In this example 200304506 both sides are configured with linear contact opposite each other. In the case of single-sided processing of the product, the pressure of the linear contact 20 is borne by a branch 31 on the opposite side. The support 31 may be provided with an inclined surface and fixed thereon. Preferably, the support 31 is provided with an elastic bracket at the travel device. In the tightly pressed state of the contact, the support will follow the product due to static friction. As in the case of this linear contact, backhauling is performed by mechanical release. In the case of single-sided processing of product 1, the rise of linear contact 2 () can also be performed by the related motion of the product itself. In this example, a stroke device operates the transfer member to transfer the product or a stand that operates the product; thus, the stroke device 28 is not required. In this example, a bracket or various brackets 12 are mounted on the fixed casing of the electrolytic machine. If the weight of product 1 is relatively light and the weight of the linear contact is heavier, then such contact will have advantages, such as when processing wafers, mixing, or processing only one side of a film or smart card. In this application example and all other application examples of the present invention, the electrolytic cell current source 30 is preferably turned off before the linear contact rises from the surface of the product, and is turned on only after the linear contact is placed next time. This avoids possible open circuit sparks from the electrolytic cell current and undesired deposits on the contact generating surface 27. When the handle 22 is damaged, the contact rods 23, 24 are coated with metal. When the linear contact is raised, an electrode 29 can be used as a cathode to remove the metal coating by a reverse device, or the anodized product itself can be used to remove the metal coating of the contact rod. The linear contact shank 22 is composed of a hard or elastic electrical insulating material. The contact rods 23 and 24 are embedded in the shank 22. Only exposed contact produces 7 200304506 surface 27. The contact rods 23 and 24 pass through the linear conductive 俨 1 〇, and the German electric insulation, insulation and elasticity of the conductor 10, and then further through the linear connection ^ Λ4 ^ Φ ^ ^ ^ S ^, contact the external insulation The other electrode, which is connected to the electric current source 26, is connected to the electrolytic cell, and the other pole is connected to the anode 5. Slot electricity / melon source In the processing step, the electrical properties of the handle 22 and the edge material completely seal the contact rods 23 and 24 in the direction of the electrolytic cell. ^ ^ ”Prevents cathodic contact rods 23, 24 from coating metal that does not meet requirements during electrochemical plating. As described in detail below, the present invention requires a thin linear contact 20 and / or an elastic bracket as shown in the figure. L ^ spring ^ ^ fork 1 1 In this case, the linear contact shank 22 is composed of an elastic,枋 Servant is made of chemical-resistant and electrically-insulating material. The bracket can be made of metal or plastic material, and Li Ke 3 is counted as flexible at least in the conveying direction. Therefore, an elastic contact point can be used. Set in the circle shown in Figure 1a There is a linear contact with a hard contact rod. The contact rod 23 is preferably composed of an anti-electrochemical material such as titanium or sharp. The metal can also be provided with a conductive and resistive surface coating,% precious metal. The hard contact rod 23 can be made by at least It is supported by an impulse in the handle 22. If a part of the surface of the product to be processed is coated with an insulating resistance material, the remaining blank of the product cannot be reliably contacted by the metal-coated hard contact rod 23. Therefore, the linear contact shown in FIG. 1b will be applicable. The elastic or hard conductive handle 22 is installed at the carrier 21. An elastic contact rod 24 is provided in the handle. The contact rod 24 is provided by a device such as The following conductive filling material is composed of an elastic material. In addition to the contact generating surface 27, the contact rod 24 is surrounded by the shank portion 22 and thus has an electrical insulation. This insulating material protects the contact rod 24 from discrepancy when it becomes a cathode 8 200304506 The required metal coating. Due to the elasticity of the contact bar 24, it also reliably contacts the product 1 provided with a resistance material in a part. The contact bar in another embodiment is a small metal sheet (for example, punched and then stacked) ( The thickness is 0.1 mm). The small metal sheet is stacked into a rod and then embedded in the contact rod 24 as the lower part, and is installed in the handle 22 in a closed form. The small metal sheet supports the remaining elasticity of the contact rod 24 upward And the conductive material, which therefore provides a common electrical connection of all small metal sheets to the elastic conductor 10. A movable metal contact can be oriented toward the product. In another embodiment, in order to be applicable to unevenness On the surface, the contact rod can be composed of an elastic metal brush rod. Fig. 2 illustrates a case where a product 1 is transported at different times 3 in a continuous operation machine, and is used for electronic connection. The basic principle of linear contact motion when touching the product. The linear contact is composed of a flexible and slender bracket 2 branches. The bracket is connected to the linear contact 20 by a travel device 28. The travel device system that moves the linear contact in the direction of arrow 8 Manufacture, control and drive by the know-how in mechanical engineering and automation technology. Φ The transmission driver of product 1 is permanently turned on and operates on the product via the roller 25 as shown by the symbol in Figure 2. Any number of Conveying roller 25. In addition to the roller, a rotating shaft with small wheels can be used to convey the product. This will be advantageous in the case of more sensitive films. For the application of the invention, further conveying members such as grips and conveying fixtures for the product It will be applicable. Because according to a specific embodiment of the present invention, the transmission member does not need to conduct current, so the transmission member may be composed of non-conductive material and can be manufactured with low cost It's time to build a production line. Pending products! The electronic contact can be applied by linear contact 20. This linear contact is usually arranged between the conveying rollers 25 and becomes a strip-shaped contact extending across the entire conveying path of the product, which means perpendicular to the conveying path. The strip contact may also be configured at an angle of 19 to 90 degrees obliquely to the product transport direction. In this case, contact the electronics with one or two edges of the product. Linear contact configurations that contact the three or four sides of the product in strip, cube, or cylindrical shapes are all feasible. Furthermore, the elongated contacts can be arranged alternately in the conveying direction 29 and symmetrically to the middle of the continuous operation ', and can be implemented with a length shorter than the width of the conveying path. The linear contact may also be arranged in the area of the roller immediately after the transfer direction 19. In this configuration, one or each edge of the product i will also be contacted by the electronics. In this regard, linear touches of shapes such as cubic or cylindrical contacts are particularly suitable. In all examples, a linear contact 20 having a contact generating surface 27 is pressed by a stroke device 28 from a starting position to the surface of the article 1 to be contacted electronically. Due to the static friction A, the continuously conveyed product j moves the linear contact 20 and the contact generating surface 27 in the same pressure state in the moving direction 2. Therefore, as shown in Fig. 2, the elastic bracket 12 is mechanically bent and deformed mechanically. After a contact segment, the linear contact is lifted from the product by means of a stroke assembly, wherein the bracket i 2 is released again. Therefore, the linear motion moves backwards and quickly returns to the starting position in the opposite direction. The sexual contact was then pressed against the product surface again and the procedure repeated cyclically. At the moment when the line contact pressure is applied to the surface of each product, the individual cell current 10 200304506 source switch is turned on and has the required polarity. In fact, each linear contact is supplied with current from a cell current source for processing. In this example, the linear contact is switched to the source of the electrolytic cell current by an electronic or electromechanical switch at time t2 to ί5. Before the linear contact is lifted off the product, the relevant cell current source should preferably be switched off. As a result, wear of the contact rods 23, 24 can be avoided. An electronic control can be used to synchronize the action steps. In this regard, electronic switches and controls of the prior art (which are not shown in the figure) can be used. The electrolyte flow device in each machine also belongs to the prior art and is not shown in the figure. Figure 2 shows the linear contact position of the product during the electrolytic treatment at time 3 from t1 to t7. At time 11 the linear contact is raised and the device is tied in a loose position. At 12 o'clock, the linear contact performs electronic contact with the product by the travel device 28. In this example, the linear contact is stopped on the product 1. Then, the electrolytic cell current is turned on. The transferred product 1 drives the contact generating surface 27 of the linear contact 20. The bracket 12 is more curved. At 15 o'clock, the source of cell current was turned off. At the same time the linear contact rises from the product. Time corresponds to time 11. This sequence is repeated repeatedly. Many linear contacts are provided in a continuous operation machine. These linear contacts can each be active at different times. If the first linear contact is contacting the product at this time, the second contact adjacent to the first contact may have been raised and is in the released position. The product to be processed can then be connected to these electrolytic cell current sources without interruption. In the example of the linear contact spanning the conveying path, the bracket 12 is advantageously arranged on both sides of the conveying path. "In the case of contacting the edge of the product, 11 200304506 only requires the rod on one side and the arrow between ΛM Λ is the smallest When the demand is released, there is no high degree of determination for the process device. In the second figure, the linear contact 2 and 8 indicate the direction of the linear contact movement between the moments 3 and 4 in each flavor. The light path is the same degree, about 1mm. In addition, the linear contact should be made obstructive. The possible length of each contact portion of the cycle is in the range of 1 mm to 250 mm depending on the stent 12. Figure 3 demonstrates that the present invention further extends to cubic and cylindrical contact. The part 22 is composed of an elastic material. If the contact portion is long enough, the linear connection is in this embodiment. The elastic material of the conductor is preferably a sealed contact bar electric field. Specific embodiment, and preferably applicable In this example, the handle of the linear contact must be relatively elongated in order to reach the foot in each cycle. 10 must be flexible. Handle 22, 23, 24 to prevent the

Fig. 4 illustrates a specific advantageous embodiment in which the linear contact is raised and pressed on the surface of the product 1 to be processed. The movement of the stroke is directly guided by the transmission driver of the product and controlled by the cam. The transfer roller or transfer wheel 25 transfers the product through the electrolytic processing space 16 to the transfer direction indicated by arrow 19. Each linear contact 20 is installed on one leg 11 or Zanqu beam. The side of the foot supported on a point 9 or on the curved beam is supported on the side inside the support point, where the point is fixed. The curved beam is pressed by a force in the direction of an arrow 6. This causes the linear contact to exert pressure on the product 1. The force can be increased by, for example, a spring or by gravity. As for the curved beam 11 below, a weight must be provided on the opposite side of the fulcrum 9. One side of the roller 25 is provided with a stroke controllable linear contact 20 12 200304506

作 之 CAM7. As shown in Figure 4, the cam 7 interrupts the electronic contact (open circuit) product 1 at the dead point 4 above each rolling rotation. In order to achieve a shorter processing step, the cam system is provided with various top dead centers, similar to a gear. The same principle can be applied to the cam 7 at the lower surface of the product. The roller 25 is set via a gear driver. Therefore, a certain position can be given in relation to the cam. This allows a linear contact to be raised in a one-by-one configuration at different times in the transfer direction. The product 1 can thus be contacted electronically without interruption, even if some linear contacts have been raised at this point. As shown in Fig. 4, each of the fourth linear contacts is simultaneously opened. The other trilinear contacts conduct this current. The relative position determined between the cam and the transfer of the product allows the electrical or electronic switch to reliably and simultaneously turn each linear contact on or off. This particular embodiment of the invention is particularly advantageous because the actuation of the linear contact does not require further drivers or components for control and synchronization.

In the case of single-sided treatment, single-sided contact with the product surface will be implemented. Linear contact on the opposite side of the product must be supported. The flat body will therefore act as a support 3 1. When processing the two sides of the product, both sides are provided with linear contact 20 and travel device. To support the electrochemical process, a shaking device or oscillator acting on the linear contact can be used to vibrate the product 1. Therefore, the electrolyte exchange on the surface of the product to be treated and the holes will increase. This provides higher current density applications. The electric conductor 26 disposed outside the electric ore cell conducts the electrolytic cell current from the electrolytic cell current source 30 through the adjacent electrode 5 or a switch at the linear contact 20. 13 200304506 After connecting 26 i will flow. Sex. Middle finger touch. Contact elasticity in its glue. Composition Inches are one meter of electrical complex meter high exposure to seconds to length. The cell current near the machine is conducted to the linear contact through insulated copper wire harnesses L for two currents.蜩. This current conductor is almost undamaged. The electrolytic cell current can be DC lightning and electricity or early or bipolar pulsed electricity has been indicated in the figure for the lightning operation of product 1 < the main operating electrode of chemical plating. If the linear contact is made, the metal coating item needs to be removed. In Mumbu, the polarity shown in parentheses will be used. The metal hard contact bar 23 is particularly suitable < π% 磙 Comprehensive connection of the product If an electrically insulating resistance material is used to form a structure on the surface of the α-supplier, the conductive surface area is impossible. In this case, a linear contact with a contact rod 24 of a conductive material may be used. Such materials are, for example, elastomers, stone rubber or rubber provided with conductive fillers during production. The fillers are made of metal powder, metal flakes or similar particles. It is preferred to use chemically resistant metal particles. The diameter of the particles is in the range of 1 micrometer to 10 micrometers. Therefore, it is possible to manufacture a composite material having a conductivity close to that of a general anti-electrochemical material such as titanium or a button. In this way, the elastic contact rod 24 can be used to bridge an impedance layer having about 40 micrometers, and therefore, the product can be contacted with the product (such as the edge of the product) in a relatively large area such as the surface is not coated with the impedance material. The possible electrolytic treatment period per cycle depends on the transfer rate, electrode size, applied current density, strength of the electrolyte flowing to the product, and the time required. The duration of each cycle or processing step is in the range of 10 milliminutes. In industrial-grade manufacturing machines, a processing step ranges from 1 mm to 250 mm. After each processing step, the line is set to leave the linear contact vertically in the direction of arrow 8, among which 14 200304506 should reduce the current intensity of the electrolytic cell current source 30, or should be completely closed to avoid open sparks at the contact rod . If the linear contact extends across the product, no electrochemical treatment will be performed below the linearity. This treatment step is applicable to the distance between each of the linear contacts, so that all surface areas of the product are electrochemically treated in a continuous operation machine at the same time. The linear contact 20 can be arranged obliquely, and its oblique angle can reach 90 degrees with the transmission direction. The linear contact of this configuration can touch the two parts of the product. This prevents the linear contact from being caught between two consecutive product gaps. As such, individual anodes may have individual bevels. The electronic contact principle of the product according to the invention can also be applied to the contact electrode already in German patent document DE 100 43 8 17 A1. The contact electrode system is supported by at least one elastic support. In a continuous operation machine according to the present invention, the electronic contact of the product is further characterized by the following description: no electrical sliding contact is required, because the supply of current through the linear contact through a copper strand or a conductive conductor such as the Wear will occur Sliding contact wear as known in the art will not occur. Furthermore, unlike the contact rollers of the prior art, the contacts 23 and 24 are suitable for being electrically insulated in an extremely easy and reliable manner. Electrochemical electroplating can reliably avoid unsuitable gold cloth at the contacts. The distance between two consecutive contact parts of the dagger in the conveying direction is the same. The anode length of the present invention is longer than the contact roller in the prior art to avoid contact between the medium and the sender. It has a twisted wire such as a stylus. In the case of the coating case, 200304506, the machine with the same performance will be significantly shorter. The invention is also applicable to the production of chemical electroless metal coating tanks. Child contact. The potential energy of the contact member and the cathode is connected to the product. At least the power supply electrode (which is on the opposite side of the product) is the anode. The formation of the cathode 2 product will support the metal coating process. The necessary device for circulating the electrolyte in the electrolytic cell and the device for the electrolyte belong to the prior art and are not shown in the drawings. These patterns can also be used in continuous operation machines with vertical transfer. In this case, the schematic illustration in the figure will represent the top view. Although the present invention is exemplified by the description of a preferred embodiment, those skilled in the art should understand the various modifications, additions and substitutions of the present invention; it is feasible and does not depart from the scope or scope of the present invention as disclosed in the scope of subsequent patent applications .
