[0051] The working method of the 3M adhesive laminating fully automatic linear production line of the present invention comprises the following steps:

[0052] S1, the empty product carrier 2 starts from the upper double-speed chain 1, and the upper double-speed chain 1 drives the empty product carrier 2 to the manual loading and unloading station, where the manual part is clamped on the product carrier 2;

[0053] S2, the upper speed chain 1 transports the product carrier 2 with the clamped parts to the grinding and brushing unit 5 station;

[0054] S3. The first robot 6 clamps the product carrier 2 on the upper double-speed chain 1 and moves the product carrier 2 to the processing position above the first waste collection hopper 59;

[0055] S4. The grinding lift drive cylinder 55 drives the grinder 56 to descend, and the brush bottom lift drive cylinder 57 drives the rubber brush head 58 to retract, so that the grinding head of the grinder 56 is lower than the rubber brush head 58. During the above process, the first robot 6 drives the front and back sides of the product carrier 2 to switch, so that the grinder 56 drives the grinding head to grind the front and back sides of the parts on the product carrier 2;

[0056] S5. After polishing is completed, the polishing lifting drive cylinder 55 drives the polishing machine 56 to rise, and the brush bottom lifting drive cylinder 57 drives the glue brush head 58 to descend, so that the glue brush head 58 is lower than the polishing head of the polishing machine 56. During the above process, the first robot 6 drives the front and back sides of the product carrier 2 to switch, so that the glue brush head 58 applies the primer to the position polished in step S4;

[0057] S6, coating the outer wall, the first robot 6 sends the product carrier 2 back to the upper double-speed chain 1, and the upper double-speed chain 1 drives the product carrier 2 to continue to move in a straight line, and moves to the primer baking unit 7 to stop;

[0058] S7: The product carrier 2 is positioned between the lower heating tube 72 and the upper heating tube 75. The opening and closing driving cylinder 74 drives the upper heating tube 75 to a suitable height. The lower heating tube 72 and the upper heating tube 75 heat the primer on the parts on the product carrier 2 simultaneously to bake.

[0059] S8, after baking, the upper speed chain 1 drives the product carrier 2 to continue to move linearly to the first gluing unit 8, which sticks 10MM wide 3M tape on the parts;

[0060] S9, after gluing is completed, the upper speed chain 1 drives the product carrier 2 to continue to move in a straight line, and moves to the front and back gluing unit 9. The second robot 10 clamps the product carrier 2. The front and back gluing unit 9 first sticks 7MM wide 3M tape on the front of the part. Then the second robot 10 flips the product carrier 2 180° so that the back of the product carrier 2 faces upward. The front and back gluing unit 9 sticks 7MM wide 3M tape on the back of the part. The second robot 10 flips the product carrier 2 180° and places the product carrier 2 with the front side facing upward on the upper speed chain 1;

[0061] S10, the upper speed chain 1 drives the product carrier 2 to continue to move linearly, and moves to the pressure holding unit 20. The piston rods of the upper pressure cylinder 204 and the lower push cylinder 205 extend, pushing the contoured pressing blocks on the upper pressure holding plate 206 and the lower pressure holding plate 207 to press the parts on the product carrier 2 at the gluing position for pressing;

[0062] S11, after the pressing is completed, the upper speed chain 1 drives the product carrier 2 to continue to move linearly to the polishing unit 30;

[0063] S12, the third robot 50 clamps the product carrier 2 and places it on the carrier support device 300;

[0064] The working steps of the carrier support device 300 are as follows:

[0065] S12-1, product carrier 2 is placed on rectangular pad 1 3013 and rectangular pad 2 3014;

[0066] S12-2. The carrier locking assemblies 3015 on the bearing support seat 1 309 and the bearing support seat 2 3010 are simultaneously actuated, and the piston rod of the locking drive cylinder 3016 extends, pushing the locking plug 3018 toward the product carrier 2.

[0067] S12-3. The locking plug 3018 drives the rectangular protrusion 3024 to move. Since the rectangular protrusion 3024 is fixedly connected to the locking movable block 3019, the locking movable block 3019 moves along the guide slot 3022 toward the product carrier 2 until the end of the locking movable block 3019 extends out of the guide slot 3022 and presses against the carrier bottom plate 21. At this time, the product carrier 2 and the rectangular connecting plate 307 are connected together.

[0068] S13, the polishing robot 303 drives the polishing head to polish the 3M adhesive cellophane location on the front surface of the part on the product carrier 2, so that the 3M adhesive cellophane location becomes thinner;

[0069] S14. The polishing of the cellophane tape on the front 3M adhesive is completed. The polishing rotation drive motor 305 drives the rotating shaft 1 306 to rotate. Since the rotating shaft 1 306, the rectangular connecting plate 307 and the shaft 2 308 are all connected as a whole, the rectangular connecting plate 307 rotates accordingly.

[0070] S15. Since the product carrier 2 and the rectangular connecting plate 307 are deposited together, the product carrier 2 rotates, causing the parts on the product carrier 2 to rotate by a certain angle;

[0071] S16, the polishing robot 303 drives the polishing head to polish the 3M adhesive cellophane location on the reverse side of the component on the product carrier 2, so that the 3M adhesive cellophane location becomes thinner;

[0072] S17: After polishing, the third robot 50 clamps the product carrier 2 and places it in the cellophane welding unit 40;

[0073] S18, the cellophane welding unit 40 adheres the cellophane to the polishing position. The cellophane is adhered here so that the 3M adhesive can be easily removed by grasping the cellophane welding unit 40 when the parts are assembled and used later.

[0074] S19: After the cellophane is bonded, the third robot 50 grips the product carrier 2 and places it at the starting end of the lower speed chain 3;

[0075] S20, the lower speed chain 3 transports the product carrier 2 to the manual loading and unloading station, and the parts on the product carrier 2 are manually removed;

[0076] S21, the empty product carrier 2 is transported to the starting end of the lower double-speed chain 3, and as the lower double-speed chain 3 pushes, the empty product carrier 2 enters the lifting conveyor belt 44;

[0077] S22, the empty product carrier 2 completely enters the lifting conveyor belt 44, and the lifting drive cylinder 42 drives the empty product carrier 2 to rise until the lifting conveyor belt 44 docks with the starting end of the upper speed chain 1, and the lifting conveyor belt 44 drives the empty product carrier 2 into the starting end of the upper speed chain 1;

[0078] S23, continuously repeating the above steps S1 to S22, and performing production in a continuous cycle.

[0079] It should be noted in the above step S15 that: the locking drive cylinder 3016, the locking connecting block 3017 and the locking plug 3018 are fixed on the bearing support seat, and the locking moving block 3019, the locking fixed block 3020 and the locking guide block 3021 are arranged on the rotating shaft 1 306 and the rotating shaft 2 308 and rotate with the rotating shaft. The structure for realizing rotation is that the locking plug 3018 is inserted into the U-shaped groove 3025, so the rectangular protrusion 3024 rotates around the locking plug 3018, that is, the rectangular protrusion 3024 rotates relative to the other side of the locking connecting block 3017, thereby keeping the locking plug 3018 always pushing up and locking. The moving block 3019 causes the locking moving block 3019 to press the product carrier 2 to prevent the product carrier 2 from separating from the carrier support device 300. When the product carrier 2 needs to be separated from the carrier support device 300, the piston rod of the locking drive cylinder 3016 is retracted, driving the locking plug 3018 to be pulled out from the U-shaped groove 3025. Since a reset spring is provided between the locking moving block 3019 and the locking fixed block 3020, the elastic restoring force of the reset spring causes the locking moving block 3019 to be retracted into the guide groove 3022, that is, at this time the locking moving block 3019 no longer presses the product carrier 2, so that the third robot 50 can take out the product carrier 2.

[0080] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
