Description

Technical Field

[0001] This invention belongs to the field of assembly and welding technology, specifically a welding device for assembling electronic device components. Background Technology

[0002] As the core actuator in various electronic and electrical equipment that converts electrical energy into mechanical energy, the electric motor is widely used in home appliances, automotive electronics, industrial servo systems, drones, and precision instruments. From the perspective of electronic component structure, the electric motor mainly consists of stator windings, rotor, insulating frame, terminals, leads, and housing. Among them, the motor leads are the key connection structure for connecting the winding coils to the external circuit. They are usually enameled copper round wire, multi-strand stranded enameled wire, or flat wire, wrapped with a high-strength insulating varnish layer such as polyester or polyimide. The ends need to be reliably soldered to metal terminals, PCB pads, or lead bundles to ensure stable current transmission, reduce contact resistance, and meet long-term reliability requirements under vibration and high-temperature conditions. Currently, existing motor lead wire welding processes still largely rely on manual labor, resulting in numerous technological defects. Firstly, enameled leads are soft and prone to shifting, making it difficult to ensure a tight fit between the lead and terminal during manual connection. This easily leads to lead misalignment and excessive gaps, resulting in defects such as incomplete welds, false welds, and misaligned solder joints, leading to poor weld consistency and a high defect rate. Secondly, traditional insulation removal methods often involve manual scraping and grinding, which is not only cumbersome and inefficient, but also difficult to control the scraping force, easily damaging the internal copper core, causing lead wire breakage, reduced conductor cross-sectional area, and decreased motor electrical performance.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a welding device for assembling electronic device components, comprising a motor cylinder, an organic base attached to the bottom end of the motor cylinder, and multiple leads installed on the cylinder port of the motor cylinder.

[0007] Preferably, an arc-shaped support plate is slidably connected to the outer wall of the toothed grinding cylinder and the outer wall of the toothed cylinder. The bottom ends of the two L-shaped fixed rods are fixedly connected to the plate of the arc-shaped support plate. An L-shaped support plate is fixedly connected to the bottom outer wall of the arc-shaped support plate. The end of the L-shaped support plate away from the arc-shaped support plate is fitted and snapped together with the two clamping plates located on the terminal block.

[0008] Preferably, a T-shaped sliding plate is fixedly connected to the side of the arc-shaped support plate near the support plate frame, and a T-shaped groove is provided on one side of the support plate frame to slide and engage with the T-shaped sliding plate; The toothed grinding cylinder is equipped with a bearing, and a rubber washer is fixedly connected to the inner ring of the bearing. The rubber washer is bonded to the insulating layer on the surface of the lead wire. Two support rods are fixedly connected to the outer ring surface of the bearing. Sleeves are fixedly connected to both the toothed grinding cylinder and the toothed cylinder. The rods of the two support rods are also fixedly connected to the sleeves fixed on the toothed grinding cylinder.

[0009] Preferably, both T-shaped blade holders are slidably connected to sleeves fixed on the toothed grinding cylinder, and first threaded rods are rotatably sleeved in the inner plates of both T-shaped blade holders, while the sleeves fixed on the toothed grinding cylinder are correspondingly provided with threaded grooves that are threadedly connected to each of the first threaded rods.

[0010] Preferably, T-shaped plate frames are slidably connected to the upper and lower cylindrical bodies of the sleeve fixed inside the toothed cylinder. A second threaded rod is fixedly connected to the two plates near the top of the two T-shaped plate frames. The sleeve fixed to the toothed cylinder has a corresponding threaded groove for threaded connection with each of the second threaded rods. An arc plate nail rod is fixedly connected to the plate at the end of the two T-shaped plate frames that are close to each other. Multiple nail rods in the two arc plate nail rod plates can contact the insulation layer on the surface of the lead wire.

[0011] Preferably, the supply structure includes a support plate, a protective cylinder is fixedly connected to the outer wall of the support plate on the side away from the lead wire, a telescopic pole is fixedly connected to the inner wall of the protective cylinder, the movable end of the telescopic pole is slidably connected to the plate body of the support plate, and a chuck is fixedly connected to the movable end, and the welding rod is tightly engaged inside the chuck.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses symmetrical clamping plates to rigidly hold the motor leads and terminals, locally rigidifying the soft and easily wobbly wires. This effectively prevents lead misalignment and swaying during welding, ensuring precise contact between the leads and terminals, providing effective positioning, reducing incomplete or false welds, and resulting in neat and reliable weld points. The invention employs a meshing rotation structure to drive a T-shaped blade holder to circumferentially cut the insulation layer. In conjunction with the counter-rotating T-shaped blade holder, the insulation layer of the circumferentially cut section is twisted and peeled off. The circumferential cutting depth is controllable and does not damage the wire core. The peeling process does not require manual scraping, resulting in higher efficiency and better wire integrity. This invention features an automatic electrode replenishment structure driven by a telescopic pole, which can accurately push the electrode and rotate it around the welding point for welding. This replaces manual close-range hand operation, reducing the risk of injury from manual contact with the welding point and improving welding consistency. The chuck, arc-shaped block, spring, and semi-circular chuck work together to achieve rapid electrode clamping and replacement, ensuring reliable clamping and simple operation. It integrates insulation stripping, lead / terminal positioning, electrode replenishment, and welding functions, enabling continuous operation from wire stripping to welding, reducing repeated manual clamping and adjustment, and improving component assembly efficiency.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figures 1 to 8 As shown, the present invention provides a welding device for assembling electronic device components, including a motor cylinder 1, an organic base 101 attached to the bottom end of the motor cylinder 1, and a plurality of leads 102 installed on the cylinder mouth of the motor cylinder 1. A workbench 103 is provided on the bottom end of the organic base 101. One end of the lead 102 is provided with a terminal 105. A welding gun 106 is provided on the table surface of the workbench 103. The welding gun 106 is used to locally heat the lead 102 and the terminal 105. Two symmetrically attached clamping plates 107 are tightly clamped on both the lead 102 and the terminal 105. Two magnetic blocks 108 and two magnetic grooves are fixedly connected to the two sides of each pair of symmetrical clamping plates 107. The two magnetic blocks 108 fixed on one side of the two clamping plates 107 can be magnetically clamped to the magnetic grooves on the other side of the two clamping plates 107, which is used to locally position and clamp the clamped wires. A processing assembly is jointly provided on the lead wire 102 and the terminal 105. The processing assembly includes a T-shaped blade holder 213 that is attached to the outer wall of the upper and lower ends of the lead wire 102. The two T-shaped blade holders 213 are jointly provided with an engagement rotation structure for moving the two T-shaped blade holders 213 downward at a fixed point and rotating them around the lead wire 102 as the center point to cut the insulation layer on its surface. A welding rod 222 for welding the two together is provided on one side of the lead wire 102 and the terminal 105. The meshing rotation structure includes a support frame 2 fixedly connected to the workbench 103. A micro motor 201 is fixedly connected to one side of the support frame 2 near the top. The output shaft of the micro motor 201 is rotatably connected to the support frame 2, and a friction turntable 202 is also fixedly connected to the output shaft. A toothed friction cylinder 203 is rotatably connected to the friction turntable 202. A first gear 204 is meshed in the inner wall of the toothed friction cylinder 203. A second gear 205 is meshed on one side of the first gear 204, and a toothed cylinder 206 is meshed on one side of the second gear 205. L-shaped fixed rods 207 are rotatably sleeved on both the first gear 204 and the second gear 205. An arc-shaped support plate 208 is slidably connected to the outer wall of the toothed friction cylinder 203 and the toothed cylinder 206. The bottom ends of the two L-shaped fixed rods 207 are fixedly connected to the plate of the arc-shaped support plate 208. An L-shaped support plate 2081 is fixedly connected to the bottom outer wall of the arc-shaped support plate 208. An arc-shaped plate is fixedly connected to the end of the L-shaped support plate 2081 away from the arc-shaped support plate 208. The annular plate and two clamping plates 107 located on the terminal 105 are fitted and snapped together. A T-shaped sliding plate 209 is fixedly connected to the side plate of the arc-shaped support plate 208 near the support plate frame 2. A T-shaped sliding plate 209 is opened on the side plate of the support plate frame 2 to slide and snap together with the T-shaped sliding plate 209. The toothed grinding cylinder 203 has a shaped groove and a bearing 210 inside. A rubber washer is fixedly connected to the inner ring of the bearing 210. The rubber washer is bonded to the insulating layer on the surface of the lead wire 102. Two support rods 211 are fixedly connected to the outer ring surface of the bearing 210. Sleeves 212 are fixedly connected to the cylinders of both the toothed grinding cylinder 203 and the toothed cylinder 206. The rods of the two support rods 211 are also fixedly connected to the sleeves 212 fixedly mounted on the toothed grinding cylinder 203.

[0019] The above solution is adopted: such as Figure 1 , Figures 2 to 3 As shown, by manually rotating the motor cylinder 1 on the base 101, the multiple leads 102 on the motor cylinder 1 can be aligned with the directions of the two T-shaped blade holders 213. Then, the two clamping plates 107 are respectively snapped onto the leads 102 and the terminals 105. Pressing firmly causes the magnetic blocks 108 and magnetic grooves fixed to each pair of clamping plates 107 to be tightly engaged, thus limiting their installation on the leads 102 and terminals 105. This transforms the originally soft, easily swaying wire segments into locally rigid segments, stably maintaining the relative position of the leads 102 and terminals 105 (they are in contact during welding), significantly reducing shaking and misalignment. This provides a clear positioning and anti-shaking effect, making it easier for workers to use the welding gun 106 to weld the two together. Figure 3 and Figure 4As shown, by activating the micro motor 201 mounted on the support frame 2, its output shaft rotates, causing the friction disc 202 to rotate. The rotating friction disc 202 then frictionally drives the connected toothed friction cylinder 203 to rotate synchronously. The toothed friction cylinder 203 then drives the first gear 204 to rotate in the same direction. Meanwhile, the second gear 205, driven by the rotation of the first gear 204, rotates in the opposite direction. This reverse rotation of the second gear 205 synchronously drives the meshing toothed cylinder 206 to rotate in the same direction. This results in the toothed friction cylinder 203 and the first gear 204 passively rotating in the forward direction, while the second gear 205 and the toothed cylinder 206 passively rotate in the reverse direction. Furthermore, the rotation of both the first gear 204 and the second gear 205 is limited by the corresponding L-shaped fixed rod 207. During the passive rotation of the toothed grinding cylinder 203 and the toothed cylinder 206, the arc-shaped support plate 208 installed at the bottom acts as a limiting point for their rotation, providing support and limiting for the toothed grinding cylinder 203 and the toothed cylinder 206. After the insulation layer on the lead wire 102 is removed, the L-shaped support plate 2081 can be held and pulled to move the arc-shaped support plate 208, causing the toothed grinding cylinder 203 and the toothed cylinder 206 and other related connecting structures to move synchronously. This allows the section of insulation layer that has been removed to be passively moved on the lead wire 102, so that it can be detached from the lead wire 102 that needs to be welded. When the arc-shaped support plate 208 is passively moved under force, the T-shaped sliding plate 209 installed on the arc-shaped support plate 208 will guide and move within the corresponding T-shaped sliding groove in the support plate frame 2, providing a smooth linear movement path.

[0020] Both T-shaped blade holders 213 are vertically slidably connected to sleeves 212 fixed on the toothed grinding cylinder 203. First threaded rods 214 are rotatably sleeved on both sides of the two T-shaped blade holders 213. The sleeves 212 fixed on the toothed grinding cylinder 203 are provided with threaded grooves that are threaded to each of the first threaded rods 214. T-shaped plate holders 215 are slidably connected to the upper and lower sides of the sleeves 212 fixed in the toothed cylinder 206. Second threaded rods 216 are fixedly connected to the two sides of the two T-shaped plate holders 215 near the top. The sleeves 212 fixed on the toothed cylinder 206 are provided with threaded grooves that are threaded to each of the second threaded rods 216. Arc plate nail rods 217 are fixedly connected to the plates of the two T-shaped plate holders 215 that are close to each other. Multiple nail rods in the plates of the two arc plate nail rods 217 can contact the insulation layer on the surface of the lead wire 102.

[0021] The above solution is adopted: such as Figure 3 and Figure 5As shown, before the micro motor 201 starts, the two T-shaped blade holders 213 and T-shaped plate holders 215, which are respectively inserted into the two sleeves 212, need to be pressed. The two T-shaped blade holders 213, which are pressed close to each other, will insert into the insulation layer on the surface of the lead wire 102 (without penetrating the insulation layer and directly contacting the lead wire 102, leaving a thin layer). The force and movement of the T-shaped blade holders 213 will drive the first threaded rod 214 and the corresponding threaded groove on the sleeve 212 to engage with each other, so that the first threaded rod 214 rotates and engages with the sleeve 212, positioning the T-shaped blade holders 213 after movement. Then, the passively rotating toothed grinding cylinder 203 will synchronously drive the sleeve 212 and the two T-shaped blade holders 213 fixed to it to rotate in the forward direction, thereby achieving circumferential cutting of the insulation layer. The process will not damage the lead wire 102. When the inner sleeve 212 is passively rotated, it will also drive the outer ring of the bearing 210 to rotate in a limited position through the two support rods 211. The two T-shaped plate frames 215, which are pressed close to each other, will synchronously drive the fixed second threaded rod 216 to move until it engages with the threaded groove on the corresponding sleeve 212, thereby positioning the T-shaped plate frame 215 after it is moved by force. The T-shaped plate frame 215, which is moved and positioned, will cause multiple nail rods on its plate to be directly driven into the insulation layer (without penetrating the insulation layer). Then, when the toothed cylinder 206 is passively rotated, it drives the fixed sleeve 212 and the two T-shaped plate frames 215 to rotate in the opposite direction, thereby driving the insulation layer that has been cut and only has a thin layer of connection to rotate in the opposite direction. This will generate a torsional force on the insulation layer in the bearing 210, so that the section of insulation layer that has been cut can be completely peeled off by force, thus not affecting the welding operation of the lead wire 102. After the insulation layer is peeled off, the section of insulation layer that has detached from the lead wire 102 can be manually pulled out from the bearing 210 and the two arc plate nail rods 217. Then, the T-shaped knife plate frame 213 and T-shaped plate frame 215 are manually pulled to reset them. Then, the L-shaped support plate 2081 is pushed to reset. During the reset process of the L-shaped support plate 2081, the clamping plate 107 that is locked by the arc-shaped plate at one end is driven synchronously, so that the terminals 105 locked in the two clamping plates 107 are synchronously moved to contact the section of lead wire 102 without insulation layer. The two are aligned and spliced. Then, the welding gun 106 can be used to weld the splice of the two.

[0022] A feeding structure capable of pushing the welding electrode 222 is provided on one side of the meshing rotation structure; The supply structure includes a support plate 218. The outer wall of the sleeve 212, which is fixedly installed inside the toothed cylinder 206, is fixedly connected to the support plate 218. A protective cylinder 219 is fixedly connected to the outer wall of the support plate 218 on the side away from the lead wire 102. A telescopic pole 220 is fixedly connected to the inner wall of the protective cylinder 219. The movable end of the telescopic pole 220 is slidably connected to the plate body of the support plate 218, and a chuck 221 is fixedly connected to the movable end. The inside of the chuck 221 is tightly engaged with the welding rod 222. Two semi-circular clamping cylinders 223 are attached to the outer wall of the welding rod 222, and the two semi-circular clamping cylinders 223 are in contact with each other. The connecting plate 218 has an arc groove on the side of the plate near the lead wire 102 that slides and fits with the two semi-circular cylinders 223. An arc-shaped block 224 is fixedly connected to the inner wall of one side of each of the two semi-circular cylinders 223. The disc of the chuck 221 can press and cooperate with the two arc-shaped blocks 224. A spring 225 is fixedly connected to the outer wall of one side of each of the two semi-circular cylinders 223. Two connecting plates 226 are fixedly connected to the side of the connecting plate 218 near the lead wire 102. The other ends of the two springs 225 away from the two semi-circular cylinders 223 are fixedly connected to the two connecting plates 226 respectively.

[0023] Using the above scheme: When welding with the welding gun 106, the operator can control the extension of the movable end of the telescopic pole 220 inside the protective cylinder 219 to push the welding rod 222 between the chuck 221 and the two semi-circular chucks 223, so that the welding rod 222 contacts the connection point of the lead wire 102 and the terminal 105, welding the two together. During the welding process, the micro motor 201 can also be activated to indirectly drive the sleeve 212 mounted on the gear cylinder 206 to rotate in the opposite direction, thereby indirectly driving the welding rod 222 to rotate in a fixed-point / circular manner at the connection point of the lead wire 102 and the terminal 105. This automates the welding point coordination and the automatic replenishment of the welding rod 222, avoiding the dangers of manual operation. To mitigate the risk, when a new welding rod 222 needs to be replaced, the movable end of the telescopic pole 220 can be retracted, causing the chuck 221 to contact the arc-shaped blocks 224 on both sides. This causes the two arc-shaped blocks 224 and the two semi-circular clamps 223 to move synchronously under force and in opposite directions. The two semi-circular clamps 223 are guided and translated in the arc groove, and they are no longer in contact with each other. During the translation process, the semi-circular clamps 223 will squeeze the spring 225, causing it to deform. This makes it easier for the worker to clamp the new welding rod 222 into the chuck 221. Then, the telescopic pole 220 drives the chuck 221 to reset. The two arc-shaped blocks 224 and the semi-circular clamps 223, which are no longer under force, will automatically reset under the action of the spring 225, thus limiting and protecting the new welding rod 222.
