Description

Device and method for adjusting and positioning tape specifications

technical field

The present invention relates to a tape reel packaging equipment, in particular to a fast tape reel specification adjustment/positioning device and method.

Background technique

After the integrated circuit (IC) is manufactured, packaged, and tested, the integrated circuit that passes the test is usually packaged in the form of a tape reel for easy handling and subsequent access. Since the tapes used in the industry come in many sizes and specifications, there must be a pre-work before the actual packaging of the tapes to set the specifications of the tapes and perform positioning; after the positioning is completed, the subsequent automation operations . Figure 1 shows a conventional tape reel gauge adjustment/positioning device. Located above the reel 12 is an image detector 11 (such as a charge-coupled device (CCD) image detector), which is mainly used to check whether the filled integrated circuit (IC) has pin defects or is placed upside down. . At the other end of the tape 12, there are a center hole detector 14 and a chain hole detector 15.

Figure 2 shows two tape spaces, each with a middle hole 13, and the distance (A) between adjacent middle holes is the pitch specification of the tape; the most common users in the industry are 8 and 12 , 16, 20 mm (mm) specifications. The distance (B) between adjacent chain holes 16 is usually fixed at 4 millimeters (mm). Additionally, the lateral distance (C) between the central hole 13 and the closest chain hole 16 is 2 millimeters (mm).

As shown in Figure 1, the traditional tape-and-reel packaging equipment needs to be adjusted and positioned before the tape-and-reel packaging, usually in two stages: (1) firstly, the center hole 13 is aligned with the image detector 11 and the center The hole detector 14 also detects another middle hole; (2) Next, slightly adjust the web 12 so that the chain hole detector 15 also detects the chain hole 16 . Only in this way can the specification adjustment and positioning of the tape be completed. This traditional two-stage positioning adjustment takes considerable time and manpower, and cannot increase production capacity; moreover, the traditional tape and reel packaging equipment uses too many detectors, which only increases the cost of equipment and maintenance.

Therefore, there is an urgent need to propose a novel and fast tape reel specification adjustment/positioning device and method to increase speed, reduce cost, and increase production capacity.

Contents of the invention

One of the purposes of the present invention is to speed up the adjustment and positioning of tape reel specifications, so as to increase production capacity and reduce equipment costs.

According to the above purpose, the present invention provides a tape specification adjustment and positioning device, which includes an image detector located above the tape; and a detector for detecting the center hole of the tape. There is a fixed distance between the above-mentioned image detector and the detector, and there is an integer multiple relationship between the fixed distance and various tape specifications, for example, the fixed distance is a common multiple of each tape specification, and the tape specification is The distance between adjacent holes.

According to the embodiment of the present invention, first align the center of an image detector with the middle hole of the tape; then, fix the image detector and the middle hole detector at a fixed distance, and there is a distance between the fixed distance and each tape specification double relationship. Finally, another center hole is detected by the center hole detector, that is, the previous positioning operation of the tape and reel packaging is completed.

Detailed ways

FIG. 3 shows a quick reel (tape reel) specification adjustment/positioning device and method according to an embodiment of the present invention. In the embodiment of the present invention, the image detector 31 is placed above the discharge end of the tape 32, and its center is aligned with the connection line of each middle hole 33 of the tape 32; the image detector 31 here can use an array charge-coupled A component (CCD) image detector, other image detectors such as complementary metal oxide semiconductor (CMOS) image detectors can also be used. In the embodiment of the present invention, the image detector 31 is not only used for positioning, but also used to check whether the loaded integrated circuit (IC) has pin defects or reversed placement.

Located at the other end of the tape 32 and at a fixed distance from the image detector 31 is a hole detector 34, which is also located above the tape 32, and its center is aligned with the line connecting the holes 33 of the tape 32. The hole detector 34 is usually composed of an emitter (such as an infrared emitter) and a sensor (sensor). The light emitted is not necessarily infrared; and the sensor (sensor) can be a sensor of various forms. The hole detection The device 34 is arranged directly above and directly below the tape 32, so that the (visible/invisible) light emitted by the emitter can just pass through the middle hole 33 and be received by the sensor. When the emitted light just passes through the middle hole 33, the sensor will be excited In other cases, the sensor is in the off (off) state. Although the transmitter and the sensor in the embodiment of the present invention are respectively located on the upper and lower (or lower, upper) of the tape 32, however In other embodiments, the emitter and the sensor can also be arranged on the same side - when encountering the middle hole 33, the emitted light passes through the middle hole 33, so the sensor cannot receive the light; at other times, the emitted light is reflected back and is received by the sensor.

Since there are many kinds of tapes used in the industry, the most common users are 8, 12, 16, and 20 millimeters (mm) if they are distinguished by the pitch between the middle holes and the middle holes. In the present invention, the distance between the image detector 31 and the center hole detector 34 is set as a fixed value. In this embodiment, the common multiples of the three tapes whose specifications are 8, 12, and 20 millimeters (mm) are taken; in addition, considering the general working space, the common multiple of 360 millimeters (mm) is taken as the image detector 31 Distance from bore detector 34. If required for other specific working spaces, the distance between the image detector 31 and the center hole detector 34 can also be selected from other common multiples. In addition, if the main tape specifications in the future are no longer the three types of 8, 12, and 20 millimeters (mm), the common multiple can also be determined according to the same principle.

Since there is a fixed distance between the image detector 31 and the center hole detector 34, and this distance is a common multiple of these three tape specifications of 8, 12, and 20 millimeters (mm), therefore, the image detector 31 and the middle hole detector can be connected together. Both the hole detector 34 are used to perform fast middle hole positioning; this is not only faster than the traditional two-stage positioning adjustment, it does not need to perform chainholes (chainholes) positioning at all, and can omit the traditional chainhole detector, which not only saves Work space and can reduce the cost of tape and reel packaging equipment. Through the special placement of the image detector 31 and the center hole detector 34 in the present invention, the adjustment of the tape specifications can be easily carried out for various tape specifications; After the transmission motor and its control firmware/software) are set to the current tape specification, when the center of the image detector 31 is aligned with a center hole 33 and the center hole detector 34 also detects another center hole 33 , that is, the adjustment of the tape and tape specifications is achieved, and the previous work of tape and reel packaging is completed.

In the above-described embodiment, the fixed distance between the image detector 31 and the hole detector 34 depends on the common multiple of these three tape specifications of 8, 12, and 20 millimeters (mm); however, there is also a 16 millimeter (mm) roll Band specs we haven't mentioned yet. Since 360 millimeters (mm) is not a multiple of 16 millimeters (mm), we need to add a simple fine-tuning mechanism (also known as a switching device) to solve the tape of 16 millimeters (mm) specification. FIG. 4 shows a schematic diagram of a fine-tuning (switching) mechanism 40 according to an embodiment of the present invention. This fine-tuning mechanism (switching) 40 has two grooves 41, and the distance between grooves is set as 8 millimeters (mm); , the difference between the two is 8 mm (ie, 360-352=8). A spring 42 and positioning beads 43 are used between the middle hole detector 34 and the platform of the fine-tuning (switching) mechanism 40 . When the specification of tape is 16 millimeters (mm), then center hole detector 34 is switched to another groove direction; The distance of the hole detector 34 then becomes 352 millimeters (ie, 360-8=352). Then, as previously mentioned, as long as the controller of the tape transmission is set to the tape specification of 16 millimeters (mm), the center of the image detector 31 is aligned with a center hole 33 and the center hole detector 34 also detects When reaching another middle hole 33, promptly reach the adjustment of tape and reel specification, and finish the previous operation of tape and reel packaging.

Though the embodiment of the present invention uses the (switching) fine-tuning mechanism 40 that has groove 41, spring 42, positioning bead 43, yet, also can use the switching device of other structure; The fixed position, that is, the tape specification adjustment/positioning applicable to the present invention. In addition, although the embodiment of the present invention moves and switches the position of the center hole detector 34 ; however, in other embodiments, the center hole detector 34 can also be fixed and the position of the image detector 31 can be moved and switched.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention; all other equivalent changes or modifications that do not deviate from the spirit disclosed by the invention should be included in the following within the scope of the patent application.
