Description

Carrier with identification function

technical field

The utility model relates to a carrier, in particular to a carrier with a marking function applied in a flexible printed circuit board patching process.

Background technique

Flexible Printed Circuit Board (Flexible Printed Circuit Board, FPC) is a printed circuit made of flexible insulating substrates, which has many advantages that rigid printed circuit boards do not have. For example, it can be freely bent, wound, and folded, and can be arranged arbitrarily according to the requirements of the spatial layout, and can be moved and stretched arbitrarily in three-dimensional space, so as to achieve the integration of component assembly and wire connection. The use of FPC can greatly reduce the volume of electronic products, which is suitable for the development of electronic products in the direction of high density, miniaturization and high reliability. Therefore, FPC has been widely used in aerospace, military, mobile communications, laptop computers, computer peripherals, PDA, digital cameras and other fields or products.

With the wide application of FPC, people have higher and higher requirements for the printing accuracy and placement accuracy of FPC products. In order to ensure the accuracy of the pads of the FPC board itself, high-precision FPC products are now in the form of a single board, that is, in the SMT process of Surface Mounted Technology (SMT), the FPC board to be processed is A small piece of board is processed as a unit of FPC product. However, in the SMT production process, due to the manual positioning of the single board by using the carrier and the positioning table, the accuracy is low. Manual positioning is to place the carrier with positioning holes (the carrier has positioning holes at the position of the positioning veneer, and the positioning pins on the positioning table pass directly through the positioning holes) on the positioning table with positioning pins before the printing operation. At the same time, the thimble of the positioning jig passes through the positioning hole on the veneer, and the veneer is glued to the carrier through the high-temperature adhesive tape, so that several veneers form a "joint board" on the carrier through the positioning jig . After the printing operation, the inspection station needs to pick out the poorly printed products and mark the corresponding position on the carrier, so that the placement machine can skip this position when it detects a special mark, and will not stick to this position. piece.

In addition, since the poorly printed veneer can be used again, it is usually not to mark the bad board on the surface of the poorly printed veneer, but to cover the position of the poorly printed veneer with a dark color paper, so that the placement machine can pass the identification The gray value of the dark paper is used to distinguish a good board or a bad board, and then determine whether the veneer is placed. However, since the camera of the placement machine needs to move from the position of the first veneer to the position of the last veneer to identify a good board or a bad board, its moving stroke is relatively large and the path is long, which wastes time and reduces the cost of placement. The efficiency of the chip machine; at the same time, the paper itself is a source of static electricity, which has potential electrostatic hazards. After the paper is pasted, it needs to be fixed with adhesive tape. The operation is cumbersome and the work efficiency is low. In addition, due to the paper It will change color after passing through the furnace. Therefore, the paper cannot be recycled, and the production cost is high.

In addition, the length of the baffle 301 of the identification member 30 is greater than the length of the base 302 , so that when the identification member 30 slides in the slot 41 , it can cover the through hole 20 of the carrier body 10 .

Fig. 5 is a diagram showing the use state of the carrier with identification function of the present invention. The veneers 51, 52, 53, 54 are pasted on the carrier body 10 by high-temperature adhesive tape, and the identification pieces 31, 32, 33 corresponding to the veneers 51, 52, 53, 54 are arranged on one side of the carrier body 10 , 34. In this embodiment, the number of veneers to be processed is four, so the number of corresponding identification parts and through holes is also four. In other embodiments of the present invention, the number of identification pieces and through holes on the carrier with identification function changes with the number of veneers to be processed. In other words, there is a one-to-one correspondence between the identification piece and the veneer to be processed.

After the printing process, inspectors check the printed veneers 51 , 52 , 53 , 54 visually or with automatic inspection equipment to confirm which veneers can be mounted and which veneers do not need to be mounted. For example, when inspectors detect that the veneer 53 is a badly printed product, they slide the identification piece 33 corresponding to the veneer 53 so that the baffle plate of the identification piece 33 can block the through hole (not shown in the figure), which is used to identify the veneer 53 is a bad board. Therefore, when the camera (not shown in the figure) of the placement machine scans the through holes sequentially, since the through holes 21, 22, 24 are not blocked by the identification pieces 31, 32, 34, the camera of the placement machine will not reflect For the placement machine, the light is equivalent to black, so the placement machine recognizes that the through holes 21, 22, and 24 are black, and the through holes blocked by the identification piece 33, because they can reflect the camera of the placement machine The light emitted is equivalent to white for the placement machine, so the placement machine recognizes that the blocked through hole is white. In this embodiment, the board is distinguished as a good board or a bad board by identifying the brightness and darkness of the through hole by the placement machine.

In addition, since the camera of the placement machine is illuminated by a light source, it needs to identify the position, and then analyze the collected reflected light to obtain an image. The image is composed of many pixels, and the color of the point is usually determined by collecting the light and shade values on the unit pixel point. For example, if the critical value of black and white is set to 150, the identified pixel point is considered to be white if it is higher than 150. If it is lower than 150, it is considered black, and finally all the pixels are combined to form the final identification pattern. Therefore, the colors that the placement machine can recognize can only be black and white. Of course, in other embodiments of the present invention, the placement machine can also be set to be white when the through hole is not blocked by the identification piece, and black when the through hole is covered by the identification piece, and will not be repeated here.

In this embodiment, when the placement machine recognizes a good board or a bad board, when the board is mounted, after the board 52 is pasted, it will automatically skip the position of the board 53 and directly paste the board 54. piece.

Therefore, the utility model can use the operator to slide the identification piece to block the through hole as a mark, and use the placement machine to identify the light and shade of the through hole, that is, whether it is blocked to distinguish the veneer as a good board or a bad board, and the operation is simple. In addition, because the camera of the placement machine only needs to scan and identify one side of the carrier body 10, that is, the position of the through hole, the moving stroke is shorter, which reduces the time taken by the placement machine for identifying bad boards and improves The efficiency of the placement machine is improved; at the same time, the marking will not generate static electricity and can be reused to reduce production costs.
