DETAILED DESCRIPTION

[0062] In order to facilitate the understanding of those skilled in the art, the utility model is further described below in combination with examples and drawings, and the content mentioned in the implementation manner is not a limitation on the utility model. The utility model is described in detail below in combination with the drawings.

[0063] The utility model embodiment provides a kind of AC seat wire harness automatic welding machine, to be used to the welding processing of AC seat, specifically as Figure 13The product shown is an AC connector and three wire harnesses soldered onto the AC connector. This invention can sequentially complete the soldering of the wire harnesses during the conveying of the AC connector. Since the wire harnesses are usually stored and conveyed in a coil, this invention provides a solution that can convey, cut, and tin the wire harnesses before soldering, thus enabling the wire harnesses to be soldered onto the AC connector. The automatic AC connector wire harness soldering machine provided in this embodiment can automatically complete the soldering of the AC connector and wire harnesses, reducing the need for extensive manual labor in production, improving production efficiency, and lowering production costs.

[0064] Specifically, such as Figures 1-12 As shown in the figure, an automatic welding machine for AC seat wire harnesses provided by this utility model includes a conveying device 100 that conveys a conveying fixture 101 with an installation groove along a predetermined direction. Along the flow direction of the conveying device 100, there are sequentially arranged a workpiece loading device 200 that provides AC seats as workpieces, at least one wire harness loading and welding device 300 that provides wire harnesses and welds them onto the AC seats, and a unloading device 400. In this embodiment, three wire harness loading and welding devices 300 are arranged side-by-side, thereby enabling the sequential welding of three wire harnesses onto the AC seat. The workpiece loading device 200 includes a vibratory feeder 201 and a loading assembly 210. The vibratory feeder 201 contains AC seats. As a workpiece, it is vibrated and conveyed to the outlet position. The feeding assembly 210 includes a first linear module 211 extending above the conveying device 100 and a workpiece picking gripper 212 driven by the first linear module 211. The AC seat is stored in the vibratory feeder 201 and is conveyed towards the outlet by vibration. The first linear module 211 and the workpiece picking gripper 212 grab the AC seat located at the outlet position of the vibratory feeder 201 and place it on the conveying fixture 101 conveyed by the conveying device 100, so that the conveying fixture 101 loaded with the AC seat can flow sequentially through the three wire harness feeding and welding devices 300 arranged side by side to perform wire harness welding operations.

[0065] The wire harness feeding and welding device 300 includes a wire feeding mechanism 310, a tinning mechanism 320, and a welding mechanism. It sequentially feeds the wire harness, cuts it to a predetermined length, tinns both ends of the wire, and finally welds the wire onto the AC seat located on the conveying fixture 101. Specifically, as shown... Figures 3-9As shown, the upper wire feeding mechanism 310 includes a wire feeding roller set 311 and a cutting assembly 312 for cutting the wire harness. The tin dipping mechanism 320 is arranged beside the upper wire feeding mechanism 310 and includes a tin pot 321, a tin dipping assembly 322 reciprocating relative to the cutting assembly 312 to clamp the wire harness and dip the ends of the wire harness into the tin, a wire harness carrying assembly 323 clamping the wire harness after the dipping, and a transfer assembly 324 extending towards the conveying device 100 to receive the wire harness transferred by the wire harness carrying assembly 323. The soldering mechanism 330 is used to transfer the wire harness after the dipping and solder the wire harness on the soldering points of the workpiece conveyed by the conveying device 100. The soldering mechanism 330 includes a transfer assembly 331 corresponding to the transfer assembly 324 and transferring the wire harness to the conveying jig 101, and a soldering assembly 332 arranged above the conveying jig 101 to perform soldering.

[0066] During the feeding and soldering process, the conveying device 100 conveys the conveying jig 101 in a predetermined direction. Meanwhile, the AC socket is stored in the vibrating disc feeder 201 and is conveyed towards the outlet by vibration. The first linear module 211 and the workpiece clamping jaw 212 clamp the AC socket at the outlet of the vibrating disc feeder 201 and place the AC socket on the conveying jig 101 conveyed by the conveying device 100. The conveying jig 101 loaded with the AC socket continues to flow in the predetermined direction and is conveyed to the position corresponding to the wire harness feeding and soldering device 300 to perform the soldering work of the wire harness. Specifically, the wire harness is previously fed into the wire feeding roller set 311 and is conveyed forward under the driving of the roller set. The front end of the wire harness is cut by the cutting assembly 312 and is clamped by the tin dipping assembly 322. The tin dipping assembly 322 is used to dip the two ends of the wire harness into the soldering tin. Then, the wire harness assembly clamps the wire harness and transfers the wire harness towards the transfer assembly 324. The transfer assembly 324 conveys the wire harness after the dipping towards the conveying device 100, so that the soldering mechanism 330 clamps and solder the wire harness on the AC socket. In this embodiment, the transfer assembly 331 of the soldering mechanism 330 clamps the wire harness above the transfer assembly 324 and moves the wire harness above the conveying jig 101. The end of the wire harness is opposite to the soldering point of the AC socket. The soldering assembly 332 is used to solder the wire harness on the AC socket to complete the soldering work. It is worth noting that the working mode and process of the three wire harness feeding and soldering devices 300 are completely the same, which will not be described here. After the conveying jig 101 flows through the three wire harness feeding and soldering devices 300, three wire harnesses are respectively soldered on the AC socket to complete the processing and soldering work of the product. The discharging device 400 discharges the product from the conveying jig 101.

[0067] The technical solution provided in this embodiment enables the welding processing of workpieces on an assembly line. During the conveying and transfer process of the conveying fixture 101, the loading of AC seats, the loading and welding of multiple wire harnesses, and the unloading of materials can be completed in sequence. This reduces the degree of personnel involvement in the overall production and processing process, lowers production costs, and improves production efficiency.

[0068] In this embodiment, an example of the specific structure of the online mechanism 310 is given, such as... Figure 4 As shown, the cutting assembly 312 includes scissors 3121; the wire feeding mechanism 310 also includes a wire clamping assembly 3122 that reciprocates between the wire feeding roller assembly 311 and the scissors 3121. The wire clamping assembly 3122 includes a bracket 3123 slidably connected to the frame, and a wire clamping pneumatic clamp 3124 is fixedly mounted on the bracket 3123. During the wire feeding process, the wire bundle is conveyed by the wire feeding roller assembly 311, and the wire clamping assembly 3122 pulls the end of the wire bundle toward the scissors 3121, thereby causing the scissors 3121 to cut the wire bundle. The cut wire bundle is clamped by the wire clamping pneumatic clamp 3124, waiting for the tinning assembly 322 to pick it up.

[0069] In this embodiment, as Figures 5-6 As shown, the tin-immersion assembly 322 includes: a second linear module 3221, a rotating unit 3223, and a tin-immersion pneumatic clamp 3224. Specifically, the linear module extends toward the conveying device 100 and is equipped with a solder base 3222. The rotating unit 3223 is mounted on the solder base 3222. In this embodiment, the rotating unit 3223 can be a drive motor and a rotating shaft that is connected to the drive unit. The tin-immersion pneumatic clamp 3224 is connected to the output end of the rotating unit 3223. That is, the tin-immersion pneumatic clamp 3224 is fixedly mounted on the rotating shaft connected to the drive motor, so that the drive motor can drive the tin-immersion pneumatic clamp 3224 to rotate. The tin-immersion pneumatic clamp 3224 extends horizontally toward a direction perpendicular to the second linear module 3221, so that the tin-immersion pneumatic clamp 3224 is suspended above the tin furnace 321. Driven by the second linear module 3221, it moves towards the wire clamping pneumatic clamp 3124 and clamps the cut wire bundle, moving it to a position above the solder pot 321. At this time, the rotating unit 3223 drives the immersion pneumatic clamp 3224 to rotate, so that the clamped wire bundle gradually tilts from the horizontal direction, so that the end of the wire bundle is immersed in the solder liquid, completing the immersion of the wire bundle. The immersion of the other end of the wire bundle is the same as the above action, and will not be described in detail here.

[0070] In the embodiment, the harness carrying assembly 323 is used to clamp and carry the harness which has been immersed in tin, and comprises a rotating carrying unit 3234 and a harness carrying unit 3231. Specifically, the harness carrying unit 3231 comprises a third linear module 3232 which is arranged side by side with the second linear module 3221, and a carrying pneumatic clamp 3233 is arranged on the third linear module 3232. The rotating carrying unit 3234 is arranged between the harness carrying unit 3231 and the tin immersion assembly 322, and is used to carry the harness clamped by the tin immersion pneumatic clamp to the carrying pneumatic clamp 3233. The rotating carrying unit 3234 comprises a rotating pneumatic cylinder 3235 which is fixedly arranged, and a rotating pneumatic clamp 3236 which is drivingly connected to the rotating pneumatic cylinder 3235. Through the above structure, the components of the tin immersion mechanism 320 can be arranged more regularly and neatly.

[0071] In the embodiment, the transfer assembly 324 comprises a fourth linear module 3241 and a transfer jig 3242. The fourth linear module 3241 is arranged corresponding to the third linear module 3232 and extends towards the conveying device 100. The transfer jig 3242 is arranged on the fourth linear module 3241 and is driven by the fourth linear module 3241 to move along a straight line. The transfer jig 3242 is located below the carrying pneumatic clamp 3233 and is provided with a plurality of harness accommodating grooves 3243 in which the harness is accommodated. Specifically, the carrying driving clamp moves the harness towards the transfer jig 3242 under the driving of the third linear module 3232, so that the harness is placed in the harness accommodating grooves 3243, and then the fourth linear module 3241 drives the harness to move towards the conveying device 100.

[0072] As Figures 5-6As shown in FIG. 10, a tin scraping assembly 325 is further arranged beside the tin furnace 321, and the tin scraping assembly 325 comprises a recycling box 3251, a tin scraping seat 3252, a tin scraping plate 3254, a first air cylinder 3255 and a second air cylinder 3256.

One end of the tin scraping plate 3254 is movably arranged in the tin scraping channel 3253, and the other end of the tin scraping plate 3254 extends towards the tin furnace 321 and is bent towards the lower side. The first air cylinder 3255 is fixedly arranged above the tin scraping seat 3252 and movably connected to one end of the tin scraping plate 3254 in the tin scraping channel 3253, so as to drive the tin scraping plate 3254 to reciprocate between the recycling box 3251 and the tin furnace 321. The second air cylinder 3256 is fixedly arranged on the side of the tin scraping seat 3252 away from the first air cylinder 3255 and movably connected to the tin scraping plate 3254, so as to drive the tin scraping plate 3254 to reciprocate in the vertical direction.

[0073] Due to the low temperature of the soldering liquid surface, a layer of solidified film-shaped soldering will exist, which will affect the tin dipping effect in the tin dipping process. The tin scraping assembly 325 will scrape off the tin film. In the tin scraping process, the tin scraping plate 3254 is driven to rise by the second air cylinder 3256, and is driven to move towards the tin furnace 321 by the first air cylinder 3255 and is moved above the tin furnace 321. Then, the second air cylinder 3256 drives the tin scraping plate 3254 to move downwards, so that the tin scraping plate 3254 is in contact with the surface of the tin liquid. Then, the first air cylinder 3255 drives the tin scraping plate 3254 to retreat, so as to complete the scraping work of the tin film on the surface of the tin liquid, and the tin film is scraped into the recycling box 3251.

[0074] In this embodiment, the transfer assembly 331 is used to grab the wire harness on the transfer jig 3242 and transfer it towards the conveying jig 101. The transfer assembly 331 comprises a fifth linear module 3311 and a transfer pneumatic clamp 3312. Specifically, the fifth linear module 3311 is supported by a support leg, one end of which is suspended above the conveying device 100, and the other end extends above the transfer assembly 324.

[0075] In the embodiment, the welding assembly 332 comprises a sixth linear module 3321, a welding unit 3323 and a suction hood 3326. The sixth linear module 3321 is suspended above the conveying device 100 through a welding frame body 3322. The welding unit 3323 is arranged above the sixth linear module 3321 and is driven by the sixth linear module 3321 to move back and forth in a linear direction. The welding unit 3323 comprises a seventh linear module 3324 and a soldering gun 3325. The seventh linear module 3324 is arranged above the sixth linear module 3321 in a vertical direction. The soldering gun 3325 is fixedly arranged above the seventh linear module 3324. The suction hood 3326 is fixedly arranged on the welding frame body 3322 and located below the sixth linear module 3321. The suction hood 3326 comprises a first opening 3327 corresponding to the soldering gun and in a shape of a horn, and a second opening provided with an exhaust fan. That is, the soldering gun 3325 can move under the driving of the sixth linear module 3321 and the seventh linear module 3324 to complete the welding work. The smoke generated during the welding process is extracted by the suction hood 3326 and uniformly discharged.

[0076] As shown in Figure 1 After the welding work on the AC socket and the wire harness is completed, a thermoplastic tube needs to be sleeved on the wire harness to protect the wire harness. In the embodiment, a thermoplastic device 410 is further included. The thermoplastic device 410 is arranged beside the unloading device 400 to receive the AC socket with completed welding transferred by the unloading device 400.

In the embodiment, the operation of sleeving the thermoplastic tube is completed manually. An operator is located beside the conveying belt 411 to sleeve the thermoplastic tube on the AC socket conveyed by the conveying belt 411. When the AC socket passes through the oven 412, the oven 412 heats the thermoplastic tube to make the thermoplastic tube plastically deform to protect the wire harness.
