Description

A winding device for coils and wire harnesses Technical Field

[0001] This invention belongs to the field of coils, and particularly relates to a winding device for coils and wire harnesses. Background Technology

[0002] Existing coil and wire harness winding operations typically employ a horizontal placement of the wire harness. In this process, tinning of the wires largely relies on a soldering process. However, this horizontal winding and tinning method has the following significant drawbacks: Firstly, winding is mostly done manually. Due to the small spacing between the two wires in the wire harness (generally only about 10mm), the hand space is limited when manually winding one wire. The winding tool or the coil wire is prone to contact and scraping with the other wire, leading to deviations in the number of turns and loose coil arrangement, severely affecting winding accuracy and work efficiency. To alleviate the problem of excessively small spacing, some solutions attempt to bend the two wires outward to increase the spacing to 25mm for easier winding, but this method has obvious disadvantages. The bending process requires additional manual labor time, and after the winding is completed, the wires need to be manually restored to their initial state. Since it is difficult to accurately control the force and angle of manual operation, the wires are prone to deformation and positional shift after restoration, and cannot be completely returned to the initial arrangement state, which in turn affects the accuracy of subsequent processes and may even lead to the finished product failing to meet the standards.

[0003] On the other hand, due to structural limitations, the horizontal placement method has to adopt the soldering process to complete the soldering. The soldering process requires a complex solder flow control device, which not only has high equipment costs, but also has strict requirements for the regulation of solder flow and pressure. Improper control can easily lead to problems such as uneven soldering and solder splashing, affecting the soldering quality and working environment.

[0004] Therefore, there is an urgent need for a coil and wire harness winding device that can avoid winding interference and simplify the tinning process for winding coil wires and wire harness wires. Summary of the Invention

[0016] The beneficial effects of this invention are as follows: 1. By vertically clamping the wire harness with a clamp and operating the double winding mechanism independently, interference with the wires is avoided and the manual bending and restoration process is eliminated. Vertical soldering replaces the soldering process, reducing equipment costs and quality risks. The entire process is automated by connecting the ring guide rails, improving processing consistency and finished product yield. It can also be adapted to multiple product specifications and reduce manual dependence, effectively solving the pain points of traditional manual and horizontal processing.

[0017] 2. The fixture uses multiple slots to achieve a preset path for the wires, eliminating the need for manual bending and restoration to prevent wire deformation; the adaptive structure of the slider and spring can clamp wires of different diameters, adapting to multiple products without changing the fixture; the interconnected slot design simplifies wire threading and provides a unified guiding benchmark, facilitating precise docking at each workstation; its structured design also reduces the skill requirements for manual loading, provides a stable operating target for automated mechanisms, reduces equipment failures, and improves processing consistency and automation efficiency.

[0018] 3. Visual inspection accurately identifies uneven bottom ends of wire harness conductors. Automated modules and tilting clamping structures are used to align and correct the conductors, eliminating potential quality issues such as subsequent winding and soldering, and replacing manual correction to improve efficiency and accuracy.

[0019] 4. The first telescopic cylinder works in conjunction with the first guide shaft, and the rotating drum adjusts the angle to achieve precise hooking of the coil wire. The second clamping spring fixes the wire to ensure effective winding. The hollow wire guard rod prevents the wire bundle from bending, and the rotating drum and lifting frame work together to ensure the coil is neat and reduce damage.

[0020] 5. The spacing between the hollow wire guard rod and the wire hook can prevent the wire hook from touching another wire bundle when rotating, completely solving the problem of easy interference due to small wire spacing during manual winding; there is no need to bend the wire as in the traditional solution, saving the manual bending and restoration process, preventing wire deformation from affecting subsequent processing, and ensuring winding stability.

[0021] 6. The wire cutting assembly completes the cutting of coil wires after winding and the collection of waste wires. This not only replaces manual wire cutting to avoid operational errors, but also promptly removes waste wires to prevent them from interfering with subsequent processes. Furthermore, the waste wire collection channel enables centralized processing of waste materials.

[0022] 7. Since the distance the first cup body rises can be controlled by the slide cylinder, the flux dipping depth is consistent, avoiding the problem of inconsistent depth of manual dipping, and the retraction and return after dipping does not interfere with subsequent processes.

[0023] 8. By automatically picking up solder, scraping off tin oxide, and precisely applying solder, it avoids the problem of uneven soldering caused by manual soldering, prevents impurities from affecting the soldering quality by scraping off tin oxide, and can also adapt to the position of the conductor to complete efficient soldering.

[0024] 9. The baffle can block the front of the wire during testing, preventing the probe from contacting and bending the wire, thus ensuring the stability of the wire.

[0025] 10. The unloading mechanism can automatically complete the picking and placing of finished products and the release of wire clamps. Through the coordinated operation of multiple cylinders, it can achieve precise gripping and sorting of materials, replacing manual operation and improving unloading efficiency. At the same time, it can adapt to the clamp structure to achieve quick unlocking of wires, ensuring smooth material picking and avoiding damage to finished products caused by manual material picking.

Detailed Implementation

[0042] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0043] Contents not described in detail in this specification are prior art known to those skilled in the art. In the description of this invention, it should be understood that terms such as "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] As shown in Figures 1 to 15, the coil and wire harness winding device provided in this embodiment includes a machine base 1, and an annular guide rail conveyor line 2, a clamp 3, a wire pulling mechanism 4, a winding mechanism 5, a flux dipping mechanism 6, a soldering mechanism 7, a resistance testing mechanism 8, and a feeding mechanism 9 disposed on the machine base 1. The annular guide rail conveyor line 2 has several conveying ends, each conveying end is provided with a clamp 3. The outer side of the annular guide rail conveyor line 2 is arranged along its conveying direction with the wire pulling mechanism 4, two winding mechanisms 5, the flux dipping mechanism 6, the soldering mechanism 7, the resistance testing mechanism 8, and the feeding mechanism 9 in sequence. The right end of the annular guide rail conveyor line 2 has a feeding station 10. The left side of the feeding station 10 is provided with the wire pulling mechanism 4. The wire pulling end of the wire pulling mechanism 4, the winding end of the winding mechanism 5, the flux box 63 of the flux dipping mechanism 6, the solder box 75 of the soldering mechanism 7, and the testing end of the resistance testing mechanism 8 are all located below the clamp 3.

[0045] At the loading station 10 on the right end of the circular guide rail conveyor line 2, the operator places the coil to be processed (containing two wires) and the wire harness (containing two wires) on the clamp 3 at the conveying end, with the wire harness wires in a vertical position. The two wire harness wires maintain an initial distance in the vertical plane without additional bending. The clamp 3 positions and clamps the coil wires and the wire harness wires respectively. After loading is completed, the circular guide rail conveyor line 2 drives the clamp 3 and the coil and wire harness to pass through each station in sequence along the conveying direction: Wire pulling station: If the bottom ends of the two wires of the wire harness are not aligned, the wire pulling mechanism 4 pulls the shorter wire harness wire downwards to make the bottom ends of the two wire harness wires aligned.

[0046] Winding station: Two winding mechanisms 5 move sequentially along the conveying direction, respectively corresponding to the two wire harnesses in the vertical straight bundle that maintain an initial spacing. Because the wire harnesses are placed vertically, the two wire harnesses form an independent winding space in the vertical plane. The winding end of the winding mechanism 5 can be precisely aligned with a single wire for automated winding without manual hand tools, completely avoiding contact and scratching caused by small spacing, and without the need for additional bending of the wires. At the same time, the winding parameters (number of turns, tension) can be precisely set to ensure that the coil arrangement is neat and the number of turns is accurate.

[0047] Flux dipping station: The ends of the wound wires are immersed in flux through the flux box 63 below the fixture 3 to complete the dipping process.

[0048] Soldering station: Using the solder box 75 below the fixture 3, the ends of the wires after being dipped in flux are soldered. The vertical position makes it easy to accurately control the soldering depth.

[0049] Resistance testing station: The test end of the resistance testing mechanism 8 contacts the end of the wire from below the fixture 3 to test the conductivity and resistance value of the wire itself and the solder layer, verifying that the wire is not damaged due to winding and soldering process, and that the solder layer has no defects such as floating or oxidation, ensuring that the basic conductivity of the wire is qualified before subsequent welding.

[0050] Unloading station: Unloading mechanism 9 automatically unloads workpieces that pass the resistance test. If the test fails, the sorting mechanism is triggered to divert defective products and complete a single processing flow.

[0051] The wire harness is placed vertically by clamp 3, ensuring the two wires are in a vertical position. The winding ends of the two winding mechanisms 5 located below clamp 3 can independently wind each individual wire, eliminating the need for additional bending and avoiding contact scratches caused by the approximately 10mm spacing. This saves time on manual bending and restoration, and avoids wire deformation and positional misalignment issues caused by manual restoration, ensuring accuracy in subsequent processes. Furthermore, automated winding replaces manual labor, improving winding accuracy and work efficiency. Vertical soldering replaces the traditional horizontal soldering process, eliminating the need for complex solder flow control devices. Simultaneously, precise control of the immersion depth allows for solder amount deviation within ±0.1mm, avoiding solder splashing and uneven soldering problems associated with soldering processes, reducing solder waste, improving the working environment, and lowering the risk of burns to operators. The circular guide rail conveyor line 2 connects the entire process of wire pulling, winding, dip coating, tinning, testing, and unloading, replacing manual handling and operation. Parameters at each station can be precisely set and monitored in real time, improving workpiece processing consistency to over 99% in mass production and avoiding random errors from manual operation. Furthermore, the resistance testing stage detects and screens out tinning defects in advance, increasing the finished product yield to over 98% and reducing subsequent rework losses. The equipment can adapt to the winding requirements of coils and wire harnesses with different wire diameters and number of turns by adjusting the positioning structure and winding parameters of the clamp 3, without requiring extensive tooling changes. Simultaneously, the entire process requires only 1-2 operators for loading, significantly reducing reliance on skilled workers and alleviating labor cost pressures.

[0052] The clamp 3 includes a base 31, a positioning post 32, a mounting base 33, a first upright 34, a first clamping spring 35, a linear guide rail 36, a slider 37, a first spring 38, and a second clamping spring 39. The base 31 is located at the conveying end of the annular guide rail conveyor line 2. The top of the base 31 is provided with a positioning post 32 for positioning the coil and a mounting base 33. The first upright 34 is located on the mounting base 33. The upper part of the first upright 34 is provided with a first clamping spring 35 for clamping the wire harness. The middle part of the mounting base 33 has a limiting part 331. The left and right sides of the limiting part 331 have a first wire groove 332 and a second wire groove 333. The second wire groove 333 extends along the vertical direction of the mounting base 33, with its top end penetrating the top wall of the mounting base 33 and its bottom end penetrating the bottom wall of the mounting base 33. The first wire groove 332 extends along the front and rear directions of the mounting base 33. The cable extends upward and penetrates the top wall of the mounting base 33, with its rear end penetrating the rear side wall of the mounting base 33. Its front end communicates with the second wire groove 333. The mounting base 33 is provided with a linear guide rail 36, which passes through the limiting part 331. The linear guide rail 36 is slidably connected to two sliders 37, which are located on the left and right sides of the limiting part 331, respectively. Each slider 37 has a first spring 38 connected to the end away from the limiting part 331. One end of the first spring 38 is connected to the side wall of the mounting base 33 away from the limiting part 331. The side of the slider 37 near the limiting part 331 has a third wire groove 310. The third wire groove 310 and the second wire groove 333 enclose each other to form a wire passage 311 for the wires of the coil and the wires of the wire bundle to pass through. The left and right sides of the mounting base 33 are provided with second clamping springs 39 for clamping the wires of the coil.

[0053] The loading station 10 has two independent stations. At the coil loading station 10, the operator first places the coil on the positioning post 32, and then passes the two ends of the coil wires through the first wire groove 332 and the wire passage 311 respectively, and clamps them with the second clamping springs 39 on the left and right sides. The circular guide rail conveyor line 2 transfers the clamp 3 with the coil placed to the wire harness loading station 10. The operator vertically clamps the wire harness with the first clamping spring 35, and then passes the two wires at the bottom of the wire harness through the two wire passages 311 respectively, leaving a distance below the wire passage 311 to allow for subsequent winding and soldering, thus completing the overall loading.

[0054] The fixture 3, through the cooperation of the first wire groove 332, the second wire groove 333, and the third wire groove 310, arranges the coil wires and wire harness wires along a preset path. No additional bending of the wires is required, eliminating manual bending and restoration processes and preventing wire deformation from affecting subsequent processing. The elastic cooperation between the slider 37 and the first spring 38 forms an adaptive clamping structure, which can reliably clamp the wires through spring force and automatically adjust the spacing of the sliders 37 according to changes in wire diameter. This allows for adaptation to various products without changing the fixture 3, improving equipment versatility and reducing changeover costs. The interconnected structure of the first wire groove 332 and the second wire groove 333 allows the coil wires to naturally transition from the coil to the vertical wire passage 311 after being led out of the coil. This simplifies the coil wire threading operation and provides a unified guiding benchmark for subsequent processes such as wire pulling, winding, and soldering, ensuring precise alignment of actions at each station and improving processing consistency. The structured design of the fixture 3 simplifies the loading operation and reduces the requirement for skilled workers. Meanwhile, standardized wire paths provide stable operational targets for various automated mechanisms (winding, soldering, etc.), avoiding equipment failures caused by wire position deviations and improving overall automation efficiency.

[0055] The wire pulling mechanism 4 includes a visual inspection camera 41, a first X-axis linear module 42, a first Z-axis linear module 43, and a first finger cylinder 44. The visual inspection camera 41 and the first X-axis linear module 42 are both mounted on the machine base 1. The visual inspection camera 41 is horizontally positioned towards the fixture 3. The first Z-axis linear module 43 is mounted on the moving end of the first X-axis linear module 42. The first finger cylinder 44 is mounted on the moving end of the first Z-axis linear module 43. The clamping end of the first finger cylinder 44 is inclined upward and positioned towards the fixture 3.

[0056] When the circular guide rail conveyor 2 transfers the clamp 3 carrying the coil and wire harness to the wire pulling station, the vision inspection camera 41 is horizontally oriented towards the clamp 3, and captures in real time the exposed wire harness wire ends below the wire passage 311. The spatial position of the wire harness wire is accurately detected through image recognition technology. When it is detected that the bottom ends of the two wire harness wires are not aligned, the first X-axis linear module 42 drives the first finger cylinder 44 to move to the front of the shorter wire harness wire. Then, the first Z-axis linear module 43 drives the first finger cylinder 44 to move upward and clamp the shorter wire harness wire. Then, the first Z-axis linear module 43 drives the first finger cylinder 44 to pull the shorter wire harness wire downward until its bottom end is aligned with the bottom end of the other wire harness wire, and then it is reset.

[0057] By using visual inspection to accurately identify uneven bottom ends of wire harness conductors, and using an automated module and tilting clamping structure to align and correct the conductors, the quality risks of subsequent winding and soldering are eliminated, and manual correction is replaced to improve efficiency and accuracy.

[0058] The winding mechanism 5 includes a second Z-axis linear module 51, a lifting frame 52, a first motor 53, a drive wheel 54, a driven wheel 55, a transmission belt 56, a bearing 57, a rotating drum 58, a hollow wire guard rod 59, a first guide shaft 510, a wire hook 511, a second guide shaft 513, a connecting block 514, and a first telescopic cylinder 515. The second Z-axis linear module 51 is mounted on the machine base 1. The moving end of the second Z-axis linear module 51 is equipped with the lifting frame 52. The first motor 53, the bearing 57, and the first telescopic cylinder 515 are all mounted on the lifting frame 52. The rotating drum 58 passes through the bearing 57. The top of the first motor 53 is equipped with the drive wheel 54, and the driven wheel 55 is mounted on the rotating drum 58. The drive wheel 54 and the driven wheel 55 are connected by the transmission belt 56. A hollow wire guard rod 59 is provided at the center of the top of the rotating drum 58. A first guide groove 516 is provided on the top of the rotating drum 58 on one side of the hollow wire guard rod 59. A first guide shaft 510 is slidably connected to the first guide groove 516. A wire hook 511 is fixed at the center of the first guide shaft 510. The top of the wire hook 511 is located above the first guide shaft 510. A second guide groove 517 is provided at the center of the bottom of the rotating drum 58. A second guide shaft 513 is slidably connected to the second guide groove 517. A connecting block 514 is provided at the bottom end of the second guide shaft 513. The bottom end of the connecting block 514 abuts against the top end of the first telescopic cylinder 515. The bottom end of the wire hook 511 passes through the first guide shaft 510 and the bottom wall of the rotating drum 58, and extends to the bottom of the rotating drum 58 to connect with the connecting block.

[0059] When the circular guide rail conveyor 2 transfers the clamp 3 carrying the coil and wire harness to the winding station, the second Z-axis linear module 51 drives the lifting frame 52 to rise, so that the hollow wire guard rod 59 is fitted over the wire harness conductor; the first telescopic cylinder 515 extends, driving the hook 511 to rise above the coil conductor via the connecting block 514; the first motor 53 drives the drive wheel 54, which in turn drives the drum 58 to rotate via the transmission belt 56 and the driven wheel 55. After the hook 511 rotates with the drum 58 to a specified angle, the first telescopic cylinder 515 retracts, and the hook 511 returns to its original position under gravity, hooking the coil conductor. After the hook 511 hooks the coil conductor, the first motor 53 continues to drive the drum 58 to rotate, while the second Z-axis linear module 51 slowly descends, winding the coil conductor onto the wire harness conductor.

[0060] The first telescopic cylinder 515, in conjunction with the first guide shaft 510, controls the upward movement and reset of the wire hook 511. Combined with the rotation of the rotating drum 58, the angle of the wire hook 511 is adjusted, achieving precise hooking of the coil wire. The end of the coil wire is fixed by the second clamping spring 39 to prevent detachment during winding, ensuring effective winding. The hollow wire guard rod 59 covers the wire harness to prevent bending and deformation during winding. The rotating drum 58 drives the wire hook 511 to rotate at a uniform speed, coordinating with the lifting frame 52 for a smooth descent, ensuring neat coil arrangement and reducing the risk of wire damage. The coordinated action of the motor and the second Z-axis linear module 51 replaces manual winding, reducing operational errors. Winding parameters (rotation speed, descent speed) can be precisely controlled to adapt to different winding needs, improving batch production efficiency and consistency.

[0061] Among them, the farthest distance between the central axis of the hollow wire guard rod 59 and the hook 511 is ≤9mm. This ensures that the hook 511 will not come into contact with another wire harness during rotation, thus completely eliminating the problem of easy contact and interference caused by the small spacing of the wires during manual winding. Unlike traditional solutions, there is no need to bend the wires to increase the spacing, saving the manual bending and restoration process, avoiding wire deformation from affecting subsequent processing, and ensuring the stability of the winding process.

[0062] The winding mechanism 5 also includes a wire cutting assembly 518, which includes a first Y-axis linear module 5181, a second finger cylinder 5182, a blade 5183, a clamping block 5184, and a waste wire collection channel 5185. The first Y-axis linear module 5181 and the waste wire collection channel 5185 are both located on the machine base 1. The moving end of the first Y-axis linear module 5181 is provided with the second finger cylinder 5182. The left and right clamping ends of the second finger cylinder 5182 are each provided with a clamping block 5184. The top of one of the clamping blocks 5184 is provided with a blade 5183. The cutting edge of the blade 5183 is located on the inner side of the corresponding side clamping block 5184 near the side wall of the other clamping block 5184. The waste wire collection channel 5185 is located below the clamping block 5184.

[0063] After winding is complete, the first Y-axis linear module 5181 drives the second finger cylinder 5182 to move towards the coil wire. The second finger cylinder 5182 clamps the coil wire, causing the two left and right clamping blocks 5184 to move closer together and clamp the coil wire below the wire bundle, and then cut it with the blade 5183. Then the first Y-axis linear module 5181 retracts and resets, driving the second finger cylinder 5182 to move forward and pull the cut waste wire away from the second clamping spring 39. When it moves above the waste wire collection channel 5185, the second finger cylinder 5182 releases, and the cut waste wire is placed into the waste wire collection channel 5185 for collection.

[0064] The wire cutting assembly 518 cuts the coil wires after winding and collects the waste wires, which not only replaces manual wire cutting to avoid operational errors, but also promptly removes the waste wires to prevent them from interfering with subsequent processes. Furthermore, the waste wire collection channel 5185 enables centralized processing of waste materials.

[0065] The flux dipping mechanism 6 includes a slide cylinder 61, a first mounting bracket 62, a flux tank 63, and a first cup 64. The slide cylinder 61 and the flux tank 63 are both mounted on the machine base 1. The flux tank 63 contains flux. The top of the slide cylinder 61 is provided with the first mounting bracket 62. The bottom end of the first mounting bracket 62 extends into the flux tank 63 and is provided with the first cup 64. The top of the flux tank 63 has a first through hole 65 for the first cup 64 to pass through.

[0066] When the circular guide rail conveyor 2 transfers the clamp 3 carrying the coil and wire harness to the flux dipping station, the slide cylinder 61 first drives the first mounting bracket 62 downward, causing the first cup 64 to move downward. This allows the flux in the flux tank 63 to flow into the first cup 64. After the cup is full of flux, the slide cylinder 61 drives the first cup 64 upward, bringing it closer to the clamp 3. This allows the wound wire harness and coil wire to be dipped in flux. After dipping, the slide cylinder 61 drives the first cup 64 back into the flux tank 63 to reset. Since the distance the first cup 64 rises can be controlled by the slide cylinder 61, the flux dipping depth is consistent, avoiding the problem of inconsistent depth in manual dipping. Furthermore, the retraction and repositioning after dipping does not interfere with subsequent processes.

[0067] The tinning mechanism 7 includes a second X-axis linear module 71, a second Y-axis linear module 72, a second telescopic cylinder 73, a third Z-axis linear module 74, a tin box 75, a second mounting bracket 76, a third mounting bracket 77, a second cup body 78, a torsion spring shaft 79, a tin scraper 710, and a tin oxide collection frame 711. The second X-axis linear module 71 is mounted on the machine base 1. The moving end of the second X-axis linear module 71 is equipped with the second Y-axis linear module 72, the third Z-axis linear module 74, and the tin box 75. The tin oxide collection frame 711 is placed on one side of the tin box 75, which contains molten tin. The moving end of the second Y-axis linear module 72 is equipped with... The second telescopic cylinder 73 has a second mounting bracket 76 at its top. The second mounting bracket 76 is rotatably connected to a tin scraper 710 via a torsion spring shaft 79. The tin scraper 710 is located above the tin box 75 and the tin oxide collection frame 711. The moving end of the third Z-axis linear module 74 has a third mounting bracket 77. The bottom end of the third mounting bracket 77 extends into the tin box 75 and has a second cup 78. The top of the tin box 75 has a second through hole 712 for the second cup 78 to pass through. The side of the tin box 75 near the tin oxide collection frame 711 has a downwardly inclined tin scraper wall 713 located above the tin oxide collection frame.

[0068] When the circular guide rail conveyor 2 transfers the clamp 3 carrying the coil and wire harness to the soldering station, the third Z-axis linear module 74 drives the third mounting bracket 77 to move downwards, causing the second cup 78 to move downwards. This allows the molten solder in the solder box 75 to enter the second cup 78. After the cup is full, the third Z-axis linear module 74 drives the second cup 78 to move upwards, exposing the surface of the molten solder in the solder box 75. When the top of the second cup 78 is above the bottom of the squeegee 710, the second cup 78 stops moving upwards. The second Y-axis linear module 72 drives the second mounting bracket 76 to move forward, causing the squeegee 710 to move forward and scrape off the oxidized molten solder on the surface of the second cup 78. The scraped-off oxidized molten solder adheres to... The front side wall of the squeegee 710 needs to have its tin oxide removed. The second telescopic cylinder 73 moves the squeegee 710 upwards, then the second Y-axis linear module 72 moves it backwards to above the tin oxide collection frame 711 and behind the squeegee wall 713. The second telescopic cylinder 73 then retracts, moving the squeegee 710 downwards so that the tin oxide on it is below the bottom of the squeegee wall 713. The second Y-axis linear module 72 then moves the squeegee 710 forwards, while the second telescopic cylinder 73 slowly moves it upwards, scraping the tin oxide off the squeegee 710 through the squeegee wall 713. The torsion spring shaft 79 allows the squeegee 710 to tilt under external force and return to its original position after the force is removed. During the process of scraping the tin scraper 710 to the tin oxide frame and scraping off the tin oxide on the tin scraper 710, the second X-axis linear module 71 drives the second cup body 78 to move to the right to below the wound wire harness and coil wire. Then, the third Z-axis linear module 74 drives the second cup body 78 to move upward to near the clamp 3, so that the wound wire harness and coil wire are tinned. After tinning is completed, the second X-axis linear module 71 moves to the left to reset, and the third Z-axis linear module 74 moves downward to reset.

[0069] In this way, by automatically picking up solder, scraping off tin oxide, and precisely applying solder, the problem of uneven soldering caused by manual soldering is avoided. Scraping off tin oxide prevents impurities from affecting the soldering quality, and it can also adapt to the position of the conductor to complete efficient soldering.

[0070] The resistance testing mechanism 8 includes a fourth Z-axis linear module 81, a baffle 82, a third Y-axis linear module 83, a second stand 84, and probes 85. The fourth Z-axis linear module 81 and the third Y-axis linear module 83 are both mounted on the machine base 1. The moving end of the fourth Z-axis linear module 81 is equipped with a baffle 82, and the moving end of the third Y-axis linear module 83 is equipped with a second stand 84. The upper part of the second stand 84 is equipped with two probes 85 arranged side by side. The probes 85 are electrically connected to an external resistance testing instrument, and the detection end of the probes 85 faces the baffle 82.

[0071] When the circular guide rail conveyor 2 transfers the fixture 3 carrying the coil and wire harness to the resistance testing station, the fourth Z-axis linear module 81 drives the baffle 82 upward to the front of the wire harness conductor. Then, the third Y-axis linear module 83 drives the second stand 84 forward, causing the two probes 85 to move forward and contact the ends of the wound and tinned wires, respectively, to detect the conductivity and resistance value of the wires and the tin layer. The baffle 82 prevents the wires from being bent after the probes 85 contact them, ensuring the wires' condition, especially the vertical position of the wire harness conductor.

[0072] The unloading mechanism 9 includes a fourth Y-axis linear module 91, a fifth Z-axis linear module 92, a third finger cylinder 93, a fourth finger cylinder 94, a good product conveyor 95, a defective product collection box 96, a sixth Z-axis linear module 97, a fifth finger cylinder 98, and a column 99. The fourth Y-axis linear module 91, the good product conveyor 95, and the sixth Z-axis linear module 97 are all located on the machine base 1. The defective product collection box 96 is placed behind the good product conveyor 95, and the sixth Z-axis linear module 97 is located in front of the good product conveyor 95. The moving end of module 91 is equipped with a fifth Z-axis linear module 92. The moving end of the fifth Z-axis linear module 92 is equipped with a third finger cylinder 93 and a fourth finger cylinder 94. The fourth finger cylinder 94 is located below the third finger cylinder 93 and above the good product conveyor line 95. The moving end of the sixth Z-axis linear module 97 is equipped with a fifth finger cylinder 98. The top of the two clamping ends of the fifth finger cylinder 98 is equipped with a column 99. The bottom end of the slider 37 is equipped with a slot 312, which is located directly above the column 99.

[0073] When the circular guide rail conveyor 2 transfers the clamp 3 carrying the coil and wire harness to the unloading station, the fourth Y-axis linear module 91 drives the third finger cylinder 93 and the fourth finger cylinder 94 to move forward. Then, the fifth Z-axis linear module 92 moves downward, with the third finger cylinder 93 clamping the wire harness and the fourth finger cylinder 94 clamping the coil. Next, the sixth Z-axis linear module 97 drives the fifth finger cylinder 98 to move upward, causing the column 99 to move upward and insert into the slot 312. The fifth finger cylinder 98 opens, causing the column 99 to push the slider 37 away from the limit part 331, releasing the clamp on the wire harness. The wire harness and coil can then be removed and placed in the good product conveyor 95 or the defective product collection box 96, depending on whether they are qualified or not.

[0074] It can automatically complete the picking and placing of finished products and the release of wire clamps. Through the coordinated operation of multiple cylinders, it can achieve precise gripping and sorting of materials, replacing manual operation and improving material feeding efficiency. At the same time, it is compatible with the clamp 3 structure to enable quick unlocking of wires, ensuring smooth material picking and avoiding damage to finished products caused by manual material picking.
