[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] refer to Figure 1-Figure 4A connector harness bidirectional synchronous tinning device is shown, comprising a frame 1, a tin furnace 2 is arranged in the middle of the frame 1, a material rack 3 and a linear module 4 are arranged on both sides of the tin furnace 2 on the frame 1, a slide 401 is fixedly connected to the moving table of the linear module 4, and a harness tinning clamp assembly is arranged on both sides of the slide 401. 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. A scale can be set on the rotating bracket 502 for easy adjustment. A protrusion 5031 is arranged on the upper part of the lower clamping plate 503, and a protrusion 5031 slides on the protrusion 5031. 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. The guide pillars are slidably connected to the slide 401, and the guide pillars can guide and correct the unloading push plate 601 when it performs the unloading action.

[0024] The cooling mechanism 7 includes a lifting and adjusting bracket 701, a lifting and adjusting seat 702 and a cold air fan 703. The lifting and adjusting bracket 701 is fixedly connected to the frame 1, the lifting and adjusting seat 702 is slidably connected to the lifting and adjusting bracket 701, and the cold air fan 703 can be tilted upward to avoid blowing toward the tin furnace 2. The heights of the lifting and adjusting seat 702 and the cold air fan 703 can be adjusted, and the cold air fan 703 is fixedly connected to the lifting and adjusting seat 702.

[0025] The working principle of the present invention is as follows: when the present invention is used, the distance between the two wire harness tinning clamping assemblies is adjusted according to the length of the wire harness, the position is adjusted by sliding the lower clamping plate 503, and it is fixed by a locking screw. When the tinning process is performed, the wire harness is placed between the upper clamping plate 504 and the lower clamping plate 503. Multiple wire harnesses can be placed at the same time for each tinning process. Then, the piston rod of the clamping cylinder 505 is extended. Under the action of the inclined block 506, the upper clamping plate 504 slides to the lower clamping plate 503 to tin the wire harness. After clamping, the flip component 501 drives the flip bracket 502 to flip downward 90 degrees, and then the linear module 4 drives the slide 401 to descend, and the metal wires extending out of the gaps on the wiring harness are immersed in the tin furnace for tinning. After tinning, the linear module 4 drives the slide 401 to rise to the cooling station. After the cold air fan 703 blows air for cooling, the linear module 4 drives the slide 401 to reset, and the rotating component 501 also drives the rotating bracket 502 to a horizontal state. Finally, the unloading cylinder 6 drives the unloading push plate 601 to unload and complete the processing.
