The harness tinning clamp assembly is used to clamp the harness. The harness tinning clamp assembly comprises a flip assembly 501, a rotating bracket 502 fixed on the rotating table of the flip assembly 501, and a lower clamping plate 503 slidably connected to the rotating bracket 502.

The upper clamping plate 504 is dynamically connected, and the lower clamping plate 503 is fixed to the rotating bracket 502 by locking screws. The cross-sections of the upper clamping plate 504 and the lower clamping plate 503 are L-shaped, and a gap is left between the upper clamping plate 504 and the lower clamping plate 503. When the wiring harness is placed, the metal wires at both ends are exposed from the gap. A spring 8 is provided between the upper clamping plate 504 and the lower clamping plate 503. A clamping cylinder 505 is fixedly connected to the upper clamping plate 504, and an inclined block 506 is fixedly connected to the piston rod of the clamping cylinder 505. The upper clamping plate 504 is provided with an inclined surface corresponding to the inclined block 506. A discharge cylinder 6 is fixedly connected to the middle of the slide 401, and a cooling mechanism 7 is provided on the frame 1 between the linear module 4 and the tin furnace 2.

[0020] The end of the material rack 3 away from the linear module 4 is a horizontal section, and the end of the material rack 3 close to the linear module 4 is an inclined section. The horizontal section of the material rack 3 is provided with a yield groove 301. When the wire harness is unloaded after the tinning process is completed, the unloading cylinder 6 drives the unloading push plate 601 to push the wire harness between the upper clamping plate 504 and the lower clamping plate 503 into the material rack 3 for unloading.

[0021] Both sides of the material rack 3 and one end away from the linear module 4 are provided with upwardly bent edges, and the provision of the folded edges can prevent the wire harness from deviating and falling during the unloading process.

[0022] The flip assembly 501 includes a driving cylinder, a rack and a gear. The gear is rotatably connected to the slide 401. The flip assembly 501 is used to drive the rotating bracket 502 to flip. The rack is fixedly connected to the piston rod of the driving cylinder, and the rack is meshed with the gear.

[0023] A unloading push plate 601 is fixedly connected to the piston rod of the unloading cylinder 6, and guide pillars are fixedly connected to both ends of the unloading push plate 601.

[0025] The working principle of the present invention is as follows: When the present invention is in use, the distance between the two wire harness tin dipping clamping assemblies is adjusted according to the length of the wire harness. The position is adjusted by sliding the lower clamping plate 503 and fixed by the locking screw. When performing tin dipping processing, the wire harness is placed between the upper clamping plate 504 and the lower clamping plate 503. Multiple wire harnesses can be placed simultaneously for each tin dipping process. Then, the piston rod of the clamping cylinder 505 extends. Under the action of the inclined block 506, the upper clamping plate 504 slides towards the lower clamping plate 503 to clamp the wire harness. Then, the flipping assembly 501 drives the rotating bracket 502 to flip downward by 90 degrees. Next, the linear module 4 drives the sliding table 401 to descend. The metal wires protruding from the gap on the wire harness are immersed in the tin furnace for tin dipping. After the tin dipping is completed, the linear module 4 drives the sliding table 401 to rise to the cooling station. After the cold air fan 703 blows for cooling, the linear module 4 drives the sliding table 401 to reset. The flipping assembly 501 drives the rotating bracket 502 to flip to the horizontal state. Finally, the unloading cylinder 6 drives the unloading push plate 601 to unload the material to complete the processing.
