Description

Technical Field

[0001] This invention belongs to the field of COF product packaging, and specifically relates to a linkage device. Background Technology

[0002] COF technology uses a flexible add-on circuit board as a chip packaging carrier to combine the chip with the flexible substrate circuit, or simply refers to a flexible add-on circuit board without a packaged chip. After the COF product ILB (Internal Lead Bonding) operation is completed, a reel is used to collect the material and then move it to the POT (Plug-in) machine for glue application.

[0003] In existing technology, the transfer of material from the ILB machine to the POT machine requires four trays for material transfer. The drawbacks are: 1. Each roll of product requires four trays for both ILB receiving and POT loading (including protective tape), necessitating a large stock of reels for use. Insufficient production lines can lead to an excessive number of trays, resulting in waste. Furthermore, these trays can deform and become unusable during use. 2. Frequent unloading from the ILB and reloading to the POT by personnel results in long waiting times. 3. The time spent on unloading and reloading by personnel impacts machine output. 4. If improper editing occurs during ILB receiving, pin breakage can lead to product loss. Summary of the Invention

[0004] The purpose of this invention is to provide a linkage device that can connect the ILB receiving end to the POT loading end, reducing personnel loading and unloading, and saving personnel time; improving machine utilization efficiency and increasing output; eliminating the need for ILB receiving, avoiding product loss due to poor ILB receiving and editing; saving material trays, and reducing scrap losses caused by material tray deformation during turnover.

[0005] The objective of this invention is achieved as follows: A linkage device includes an inner lead receiving frame and an adhesive dispensing frame, with a linkage frame disposed between the inner lead receiving frame and the adhesive dispensing frame. The inner lead receiving frame has a through hole corresponding to the linkage frame, and the adhesive dispensing frame has a through hole corresponding to the linkage frame. The linkage frame includes a base, and two sets of symmetrical support components are disposed on the upper surface of the base. Each set of support components includes two front-to-back corresponding support blocks, and a pad is horizontally disposed on each of the two support blocks. Two vertical support plates are fixed on the base plate, one in front of the other, perpendicular to the base plate. An L-shaped mounting block is provided on the upper part of the two support plates, and a side guide rail is provided on the mounting block. The two side guide rails are arranged opposite each other, and a guide groove is opened on the upper part of the opposite side of each side guide rail. A central support is provided on the base, and a central support guide rail is provided on the upper part of the central support. Two side guide rails are symmetrically distributed on the left and right sides of the central support guide rail, and the central support guide rail and the two side guide rails are arranged parallel to each other.

[0006] In operation, this invention connects the ILB receiving end to the POT loading end via a linkage frame, enabling rapid connection between the inner pin mounting machine and the gluing machine. The strip is led out through the front guide rail of the inner pin receiving frame, then passes through through hole one onto the central support guide rail and two side guide rails, then through through hole two onto guide wheel two, and finally is conveyed to the working area of ​​the gluing machine. The central support guide rail supports the strip from the middle, and the guide grooves of the two side guide rails are correspondingly set on the left and right sides of the strip and serve as guides. Compared with the prior art, the advantages of this invention are: the connection between the ILB receiving end and the POT loading end via a mechanism reduces manual loading and unloading; the fixture is simple to operate and can be reused; reduced manual loading and unloading reduces waiting time, improves machine utilization, and increases output; the ILB does not require receiving, avoiding product loss due to poor ILB receiving and editing; it saves material trays and reduces scrap losses caused by deformation during tray turnover.

[0007] As a further improvement of the present invention, both the inner lead receiving frame and the glue dispensing frame are rectangular boxes. Both the inner lead receiving frame and the glue dispensing frame have an opening on the front side. Through hole one is provided on the right side baffle of the inner lead receiving frame, and through hole two is provided on the left side baffle of the glue dispensing frame. Both the inner lead receiving frame and the glue dispensing frame have at least four support legs one at the bottom, and the linkage frame has at least four support legs two at the bottom.

[0008] In order to guide and direct the material strip, a front guide rail is provided on the left side baffle of the inner lead take-up frame, a guide wheel is rotatably provided on the inner lead take-up frame corresponding to the first through hole, and a guide wheel is rotatably provided on the glue dispensing frame corresponding to the second through hole.

[0009] To facilitate adjustment of the mounting pad position along the width direction to accommodate material strips of different widths, a flat plate is provided on the upper surface of the machine base. The central support and four support blocks are all mounted on the flat plate. A waist-shaped groove is opened on the mounting pad along the width direction of the material strip. Fastening bolts pass downward through the waist-shaped groove and are fixedly connected to the screw holes on the corresponding support blocks.

[0010] To reduce friction with the material strip and prevent it from affecting the performance of the IC products on the material strip, the upper part of the central support guide rail is provided with a lower groove, and the bottom of the side guide rail guide groove is provided with several anti-friction grooves at equal intervals along the length direction. The upper surface of the central support guide rail is flush with the bottom of the side guide rail guide groove, or the height of the upper surface of the central support guide rail is lower than the bottom height of the side guide rail guide groove.

[0011] As a further improvement of the present invention, a back plate is vertically provided on the rear edge of the flat plate of the base. Two symmetrical side frames are provided on the back plate, the height of which is higher than the height of the side guide rails. A horizontal cover plate, made of transparent glass, is fixed to the lower part of the two side frames. Ion guns are obliquely arranged on the back plate corresponding to the central support rail and the material strips on the two side guide rails. A passage groove is provided on the glass plate corresponding to the ion guns. A horizontal mounting beam is provided between the two side frames. An upper camera is provided under the mounting beam, with its lens facing downwards and corresponding to the material strip. A display screen connected to the upper camera is provided on the mounting beam. An arc-shaped guide rail with an L-shaped cross-section is connected to one end of the side guide rail near the second through hole. The upper cover plate shields the IC products on the material strip, preventing the influence of dust particles. The ion gun neutralizes the charge on the ICs on the material strip through the passage groove. The upper camera takes a downward view of the ICs on the material strip, displays their structure on the display screen, and detects any abnormalities. The arc-shaped guide rail at the tail leads out the material strip, which is then transported backwards in an arc.

[0012] In order to capture the structure of the material strip and IC from below, a lower camera is provided on the inner pin receiving rack, with the lens of the lower camera facing upwards and corresponding to the material strip.

[0013] To facilitate the forward or backward transport of the conveyor belt, each of the aforementioned base plates is movably connected to a movable box that can move along its length. The movable boxes are rectangular, with openings on opposite sides. Inside each movable box is a vertically mounted rotatable lead screw. The upper and lower ends of the lead screw are rotatably connected to an upper support and a lower support, respectively. Both the upper and lower supports are fixed to the inner wall of the movable box. The lower end of the lead screw passes through the lower support and is connected to a motor. The motor is installed inside the movable box. A lead screw nut on the lead screw is connected to a lower transmission bracket. The frame is set along the width of the material belt. A lifting plate is connected to the end of the lower transmission bracket. Several lower insert teeth are evenly spaced along the length of the upper part of the lifting plate. An upper fixed bracket is set on the moving box, and an upper fixed plate is set at the end of the upper fixed bracket. Several upper insert teeth are evenly spaced along the length of the lower part of the upper fixed plate. The upper fixed plate and the lifting plate are positioned correspondingly. Multiple transmission holes are spaced apart on both sides of the material belt located between the two side guide rails. The upper and lower insert teeth correspond to the upper and lower sides of the material belt, respectively, and are staggered along the length. When the lead screw rotates, it drives the lifting plate upward through the lead screw nut, causing the lower insert teeth to insert upward into the material holes of the material belt, lifting the material belt upward. This causes the upper insert teeth of the upper fixed plate to insert downward into the material holes of the material belt from above. The upper and lower insert teeth are staggered, and the upper fixed plate and the lifting plate work together to clamp the material belt more smoothly. The moving box clamps the material belt and moves back and forth, performing a transport function. The material belt is observed on the display screen, and when the material belt is misaligned, it is clamped for correction.

[0014] To drive the moving box to move, the moving box is movably connected to two left and right corresponding guide rails on the pad plate through two sliders. The flat plate is provided with a base, and the base is rotatably provided with a second lead screw along the length direction. The second lead screw nut on the second lead screw is connected to the two moving boxes respectively through two left and right symmetrically distributed transmission components.
