The main shaft of the drive motor 12 passes through the fixed frame 11 and the fixed sleeves 13 and is fixedly connected to the connecting shaft 74. The fixed sleeves 13 are rotatably connected to the connecting plate 75. Through the above arrangement, a stable power source is provided to the first transfer member 7 and the second transfer member 8. As a further implementation of this solution, the bonding unit 3 includes a bonding box 31. Equally spaced telescopic baffles 32 are installed on both sides of the bonding box 31.

Step 2: During the process of transferring the polyetheretherketone composite board blank to the bonding box 31 by the horizontal plate 71, the rubber airbag 73 is squeezed by the lower end of the bonding box 31. At this time, the gas enters the sliding chamber 77 through the air pipe 76, the sliding block 78 is pushed out, and the piston plate 710 evacuates the upper end of the adsorption tank 79. The adsorption tank 79 is used to prevent the polyetheretherketone composite board blank from tipping over during the process of standing up. The sliding block 78 pushes the polyetheretherketone composite board blank to the side of the inclined telescopic block 6 away from the feed port 33. Step 3: Simultaneously, another part of the polyether ether ketone composite board blank is cut from the upper opening of the bonding box 31. During the cutting process, the glue application component 4 applies glue to the surface of this part of the polyether ether ketone composite board blank. After the glue application is completed, it enters the bonding box 31 and is adapted to be bonded to the polyether ether ketone composite board blank transferred by the first transfer component 7. Step 4: After the bonding is completed, the polyetheretherketone composite board moves inside the bonding box 31 pushed by the next set of feeders. During this process, it is continuously pressed by the telescopic baffle 32. The bonding box 31 can be heated internally during operation. When a bonded polyetheretherketone composite board moves out from the side away from the feed port 33, the second transfer member 8 is controlled to transfer the bonded polyetheretherketone composite board to the segmented conveyor belt 2 to complete the unloading.
