Description

Technical Field

[0001] This utility model relates to the field of ACF bonding machine technology, and in particular to an anisotropic conductive film bonding machine. Background Technology

[0002] An anisotropic conductive film (ACF) bonding machine is a device specifically designed for bonding anisotropic conductive film (ACF) onto electronic components. ACF is a polymer material mainly composed of resin adhesive and conductive particles. Its working principle involves using the conductive particles to connect the electrodes between the IC chip and the substrate, creating conductivity while simultaneously preventing short circuits between adjacent electrodes, thus achieving conductivity in the Z-axis direction.

[0003] In existing technologies, traditional ACF bonding machines mostly use a single pressing mechanism or vacuum adsorption to fix the substrate. During high-speed bonding, the substrate is prone to displacement or loosening, resulting in ACF bonding position deviation and affecting product yield. Since the size and bonding position of different substrate models vary, the pressing mechanism of existing equipment often cannot be adjusted quickly, requiring the replacement of fixtures or manual repositioning, which reduces production efficiency. Therefore, we propose an anisotropic conductive film bonding machine to solve the above problems. Utility Model Content

Two T-shaped slots are formed on the top of the guide plate. T-shaped blocks are slidably connected to the inner walls of the two T-shaped slots. The same bonding plate is fixedly connected to the top of the two T-shaped blocks. Two rectangular slots are formed on the outer wall of the bonding plate. Two strip slots are formed on the outer wall of the guide plate. L-shaped plates are slidably connected to the inner walls of the two strip slots. Straight rods are fixedly connected to the outer walls of the two L-shaped plates. Rubber sleeves are fixedly fitted onto the outer walls of the four straight rods. A lifting assembly is provided at the bottom of the L-shaped plates.

[0007] Preferably, the lifting assembly includes four threaded rods, the bottoms of the two L-shaped plates are fixedly connected to the tops of the four threaded rods respectively, the outer walls of the four threaded rods are slidably fitted with the same lifting plate, the interior of the ACF bonding machine body is fixedly connected to a frame, the top of the frame is fixedly connected to an electric push rod, the top of the output end of the electric push rod is fixedly connected to the bottom of the lifting plate, and the lifting assembly drives the four rubber sleeves to move downward to fix the position of the substrate.

[0009] Preferably, the outer walls of the four threaded rods are all threaded with nuts, and the L-shaped plate is fixed to the top of the lifting plate by setting the nuts.

[0010] Preferably, the bottom of the L-shaped plate is slidably connected to the top of the lifting plate.

[0022] Depend on Figures 1-5 As shown, an anisotropic conductive film (ACF) bonding machine is disclosed, comprising an ACF bonding machine body 1. A worktable 2 is fixedly connected to the outer wall of the ACF bonding machine body 1. The surface of the worktable 2 is flat to ensure the stability of the equipment operation. A U-shaped support 3 is fixedly connected to the top of the worktable 2. Two guide bars 4 are fixedly connected to the top of the U-shaped support 3. The two guide bars 4 assist the bonding plate 7 in linear movement. A guide plate 5 is fixedly connected to the top of the U-shaped support 3. Two T-shaped slots are formed on the top of the guide plate 5. T-shaped blocks 6 are slidably connected to the inner walls of the two T-shaped slots. The same bonding plate 7 is fixedly connected to the top of the two T-shaped blocks 6.

[0023] The outer wall of the attachment plate 7 has two rectangular grooves 8, the outer wall of the guide plate 5 has two strip grooves, the inner walls of the two strip grooves are slidably connected to L-shaped plates 9, the outer walls of the two L-shaped plates 9 are fixedly connected to straight rods 10, and the outer walls of the four straight rods 10 are fixedly fitted with rubber sleeves 11. The rubber sleeves 11 are supported by the straight rods 10 and can be replaced periodically.

[0024] The bottom of the L-shaped plate 9 is provided with a lifting assembly, which includes four threaded rods 12. The bottom of the two L-shaped plates 9 is fixedly connected to the top of the four threaded rods 12 respectively. The L-shaped plates 9 slide along the top of the lifting plate 13. The same lifting plate 13 is slidably sleeved on the outer wall of the four threaded rods 12. Two sliding grooves are opened on the outer wall of the lifting plate 13. The inner wall of the two sliding grooves is slidably connected to the outer wall of the four threaded rods 12 respectively.

[0025] The bottom of the L-shaped plate 9 is slidably connected to the top of the lifting plate 13. The ACF bonding machine body 1 is fixedly connected to the frame 14.

[0026] Working principle: When the ACF bonding machine body 1 is in use, the substrate is placed on top of the bonding plate 7. As the electric push rod 15 rotates, it drives the lifting plate 13 to move downward. The downward movement of the lifting plate 13 drives the two L-shaped plates 9 and the four straight rods 10 to move downward, thereby driving the four rubber sleeves 11 to move downward, fixing the substrate on top of the bonding plate 7 for easy subsequent bonding. The bonding plate 7 can be moved by the two T-shaped slots and the two T-shaped blocks 6 to change the subsequent bonding position of the substrate. Rotating the four nuts 16 releases the position fixation of the two L-shaped plates 9. The two L-shaped plates 9 move along the two sliding grooves and the strip groove, changing the position of the four rubber sleeves 11 to meet the fixing requirements of different substrates.
