[0033] The present invention includes a tooling, a locking mechanism 6, a first unlocking and flipping mechanism 11, and a second unlocking and flipping mechanism 15. The locking mechanism 6 can limit the horizontal position of the serpentine plate 27 clamped on the tooling. The first unlocking and flipping mechanism 11 and the second unlocking and flipping mechanism 15 can stably install the serpentine plate 27 on the tooling and flip it. The serpentine plate 27 can be stably plasma cleaned and coated with adhesive from all directions, ensuring processing quality and high processing efficiency.

[0034] In this embodiment, the feeding rack 1 can accommodate multiple serpentine plates 27, such as... Figure 1 As shown, multiple serpentine plates 27 are arranged on two loading racks 1. The loading multi-axis robotic arm 3 can drive the loading gripper 2 to clamp the serpentine plates 27 and load them onto the tooling on the main conveyor line 4. The main conveyor line 4 transports the tooling from front to back. The loading rack 1, the loading multi-axis robotic arm 3, and the barcode scanning mechanism 16 are all located on the right side of the main conveyor line 4. When the feeding gripper 2 clamps the serpentine plate 27 onto the tooling, the main conveyor line 4 is relatively stationary. The first unlocking and flipping mechanism 11 can unlock the pressing unit 71 of the tooling. The feeding gripper 2 moves the serpentine plate 27 onto the receiving groove 51 of the positioning plate 5. At this time, the locking mechanism 6 can lock the horizontal position of the positioning plate 5 to prevent the positioning plate 5 from moving left or right or back and forth, and ensure that the positioning plate 5 is fixed. Meanwhile, the scanning mechanism 16 can scan the serpentine plate 27 on the positioning plate 5, and the corresponding plasma cleaning mechanism 8 can clean the front (top) surface of the serpentine plate 27 from the bottom. After the front (top) surface of the serpentine plate 27 is cleaned, the unlocking unit 17 of the first unlocking and flipping mechanism 11 is used to unlock the latch 62 of the locking seat 61. At this time, the flipping jaw 181 of the flipping unit 18 clamps the positioning plate 5, and the flipping drive 182 drives the clamped positioning plate 5 to flip. The corresponding plasma cleaning mechanism 8 can clean the back (bottom surface before flipping) of the serpentine plate 27 from the bottom, thus cleaning the front and back of the serpentine plate 27. After cleaning, the serpentine plate 27 can be locked to the positioning plate 5 by the locking seat 61 and then transferred to the area directly below the gluing mechanism 12 via the main conveyor line 4. The gluing mechanism 12 applies glue to the top of the serpentine plate 27 clamped on the fixture. The second unlocking and flipping mechanism 15 has the same structure and working distance as the first unlocking and flipping mechanism 11. It can unlock, flip, and fix the position of the serpentine plate 27 on the fixture. Finally, it applies glue to the front and back of the serpentine plate 27, completing multi-directional scanning, cleaning, and gluing. The processing is uniform and stable, and the work efficiency is high.

[0035] Specifically, clamping grooves 53 are provided at the top and bottom of both ends of the positioning plate 5. The clamping grooves 53 are adapted to the flipping gripper 181. The flipping moving member 184 can drive the flipping gripper 181 to move left and right to insert into the clamping groove 53. The clamping positioning plate 5 is lifted by the flipping lifting member 183. The pressing block 712 of the pressing unit 71 presses down on the serpentine plate 27 located in the receiving groove 51 to achieve top limit. The flipping driving member 182 can drive the clamping positioning plate 5 to flip. After flipping, the positioning plate 5 falls into the top of the locking seat 61 through the flipping lifting member 183. The latch 62 of the locking seat 61 locks the positioning plate 5. Specifically, a spring A is provided at the end of the locking slider 63 away from the unlocking push rod 171 to provide elastic force to ensure that the latch 62 locks the positioning plate 5. When the locking slider 63 is pushed by the unlocking telescopic member 172, it overcomes the elastic force and controls the latch 62 to move away from the positioning plate 5. The lower end of the latch 62 is movably connected to the locking slider 63 via a connecting piece. The upper end of the connecting piece is located in the connecting groove of the locking seat 61 and can move up and down in the connecting groove. The lower end of the connecting piece is movably connected to the surface of the locking slider 63. The locking slider 63 slides horizontally on the locking guide rail 64. The top of the latch 62 is provided with a locking groove. The outer end of the control guide rail 76 is located in the locking groove. In this embodiment, the control slider 75 can only move outward and drive the movable rod 72 to move after the latch 62 is unlocked. Finally, the lower pressure block 712 can be unlocked before the serpentine plate 27 can be placed into the receiving groove 51 or removed from the receiving groove 51. The flipping through groove 52 is larger than the receiving groove 51 so that the serpentine plate 27 can be processed on both sides after flipping. At the same time, one end of the serpentine plate 27 is clamped and the other end is pressed by the lower pressure block 712 to achieve double-sided flipping processing.

[0036] Specifically, when the control slider 75 moves away from the receiving groove 51 along the control guide rail 76, the control member 74 can drive the control slider 75 to move. The driving unit is not shown in the attached figure of this embodiment. The driving unit can be a telescopic mechanism such as a cylinder, or the control member 74 can be manually pushed to move the connecting bar 73, thereby driving the movable rod 72 to move towards the receiving groove 51. The movable rod 72 drives the roller 22 to move along the swing groove 23 through the compression reset member 713. The gear 21, which moves synchronously with the roller 22, meshes with the rack 20 to drive the transmission, and finally drives the lower pressure block 712 to swing. Similarly, when the movable rod 72 moves away from the receiving groove 51, the roller 22 descends along the swing groove 23, thereby causing the lower pressure block 712 to swing downward to press the serpentine plate 27. In addition, the glue coating mechanism 12 and the plasma cleaning mechanism 8 are both equipped with detection units, which are not shown in this embodiment. The plasma cleaning head can be a direct-drive jet type low-temperature plasma rotary spray gun. For cleaning moving mechanisms, unloading moving mechanisms, etc., linear moving modules or other linear moving structures can be selected according to actual needs.
