Description

Technical Field

[0001] This utility model relates to the field of automated manufacturing technology, specifically to an automatic welding device for micro motors. Background Technology

[0002] The automatic welding device for micro motors can replace traditional manual welding methods for core components of micro motors, such as stator windings, rotor leads, terminals, and housing seams. By controlling parameters such as the movement trajectory of the welding head, welding temperature, pressure, and time through preset programs, it can automatically connect weld points or weld seams and ensure the consistency of the welding process.

[0003] In existing technologies, the control box of a micro-motor automatic welding device, as the core control unit, typically requires the connection of multiple external wires of different types to connect with external components and thus construct a complete automated control closed loop. To avoid tangled wires and reduce mutual interference or accidental pulling, some devices use cable ties to bundle multiple wires together and fix them to the outside of the control box for neatness. When a wire malfunctions and needs repair or replacement, the cable tie must be cut before operation can proceed. After repair, the scattered wires need to be re-bundled and fixed. This process not only increases the labor and time costs of maintenance but also indirectly reduces the maintenance efficiency of the equipment. Utility Model Content

[0004] To address the aforementioned shortcomings of existing technologies, this utility model provides an automatic welding device for micro motors, which can effectively solve the problem in existing technologies where multiple scattered wires need to be re-tied and fixed after the repair of a certain wire is completed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides an automatic welding device for micro motors, including an automatic welding device body, including a bracket, a welding box fixedly connected to the inner side of the bracket, a welding head and a clamp adapted to be installed in the inner cavity of the welding box, a control box fixedly installed on the outer side of the bracket, and a wiring groove penetrating the bottom of the control box.

[0007] The adjustment mechanism includes a clamping assembly for fixing multiple wires passing through the wiring slot, and a distance control mechanism for flexibly adjusting the spacing between the multiple wires fixed by the clamping assembly.

[0008] The clamping assembly is located directly below the wiring slot, and the number of clamping assemblies is the same as the number of wires. The distance control mechanism is located outside the clamping assembly.

[0009] Furthermore, the clamping assembly includes multiple connectors located directly below the connector slot for accommodating wires, multiple springs fixedly connected to the inner wall of the connectors for clamping the wires, an internally threaded post integrally formed on the top of the connector, an externally threaded post threaded to the inner wall of the internally threaded post, and a rotating block integrally formed on the outer end face of the externally threaded post.

[0010] Furthermore, the clamping assembly also includes a single-sided inclined block fixedly connected to the top of the spring piece, and an inclined opening opened at the end of the external threaded post away from the rotating block for applying pressure to the single-sided inclined block.

[0011] Furthermore, multiple spring clips are arranged in a circumferential array on the inner wall of the connector;

[0012] After the wire passes through the conduit, rotating the rotating block causes the external threaded post to rotate, while the external threaded post moves vertically along the internal threaded post. When the external threaded post moves downward, it can squeeze the single-sided inclined block through the inclined opening, thereby causing the single-sided inclined block to drive multiple spring pieces to retract and clamp the wire.

[0013] Furthermore, the distance control mechanism includes a fixed plate fixedly connected to the outer surface of the bracket, a threaded rod fixedly installed on the outer surface of the fixed plate via a bearing, an internal threaded block threadedly connected to the outer surface of the threaded rod, and a sliding plate fixedly connected to the outer surface of the internal threaded block.

[0014] Furthermore, the sliding plate is vertically slidably connected to the outer surface of the fixed plate;

[0015] When the threaded rod rotates, it can drive the internal threaded block to move the sliding plate vertically.

[0016] Furthermore, the distance control mechanism also includes a pitch groove that radially penetrates both sides of the sliding plate, a force-bearing column that is movably connected to the inner wall of the pitch groove, a sliding rod that is fixedly connected to the outer end face of the force-bearing column and is used to support the wiring pipe, and a force-applying end that is fixedly installed on the outer end face of the threaded rod.

[0017] Furthermore, the sliding rod is horizontally slidably connected to the outer surface of the fixed plate, and the fixed plate is fixedly connected to the outer end face of the sliding rod;

[0018] When the force-applying end is rotated to move the threaded rod, the threaded rod can drive the sliding plate to move vertically through the internal thread block, so that the sliding plate squeezes the force-receiving column through the variable pitch groove, and finally drives multiple sliding rods and wiring pipes to move horizontally at a uniform distance.

[0019] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0020] This utility model, by setting an adjustment mechanism, can not only fix multiple external wires during the automatic welding process of micro motors, but also control the multiple wires to be horizontally close together, reduce the spacing between the multiple wires, and avoid the wires being messy and exposed. Furthermore, when a certain wire fails and needs to be repaired, it can expand the spacing between the multiple wires and individually release the fixation of the faulty wire. This achieves the effect of improving equipment maintenance efficiency while ensuring the reliability of equipment during use. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The present invention will be further described below with reference to the embodiments.

[0031] Example: A micro-motor automatic welding device, see attached figure. Figure 1 - Appendix Figure 6 ,include,

[0032] The automatic welding device body 100 includes a bracket 110, a welding box 120 fixedly connected to the inside of the bracket 110, a welding head 130 and a clamp 140 adapted to be installed in the inner cavity of the welding box 120, a control box 150 fixedly installed on the outside of the bracket 110, and a wiring groove 160 penetrating the bottom of the control box 150.

[0033] It should be noted that the bracket 110 is the basic support structure of the automatic welding device body 100, used to fix core components such as the welding box 120 and the control box 150. The welding box 120 provides working space for the welding head 130 and the fixture 140. The semi-enclosed structure reduces external interference during the welding process. Under the control of the preset program, the welding head 130 can automatically weld components such as the stator winding and rotor leads of the micro motor by adjusting the movement trajectory, temperature and pressure, replacing manual operation to ensure welding consistency. The fixture 140 is used to fix the micro motor to be welded to prevent the workpiece from shifting during the welding process, so as to ensure that the welding head 130 is accurately connected to the welding part. The control box 150 is the core of automatic control. It can receive sensor signals and send instructions through its internal circuits and programs, coordinate the actions of components such as the welding head 130 and the fixture 140, and build a complete automatic control closed loop. The wiring slot 160 is used to provide a passage for multiple external wires connected to the control box 150.

[0034] The adjustment mechanism 200 includes a clamping assembly 210 for fixing multiple wires passing through the wiring slot 160, and a distance control mechanism 220 for flexibly adjusting the spacing between the multiple wires fixed by the clamping assembly 210.

[0035] The clamping assembly 210 is located directly below the wiring slot 160, and the number of clamping assemblies 210 is the same as the number of wires. The distance control mechanism 220 is located outside the clamping assembly 210.

[0036] Specifically, the clamping assembly 210 includes a plurality of wiring tubes 211 located directly below the wiring slot 160 for accommodating wires, a plurality of spring pieces 212 fixedly connected to the inner wall of the wiring tubes 211 for clamping the wires, an internally threaded post 213 integrally formed on the top of the wiring tubes 211, an externally threaded post 214 threaded to the inner wall of the internally threaded post 213, and a rotating block 215 integrally formed on the outer end face of the externally threaded post 214.

[0037] Furthermore, the clamping assembly 210 also includes a single-sided inclined block 216 fixedly connected to the top of the spring piece 212, and an inclined opening 217 opened at the end of the external threaded post 214 away from the rotating block 215 for applying pressure to the single-sided inclined block 216.

[0038] It should be noted that the conduit 211 is a tubular structure used to accommodate a single wire, for initially organizing the wire routing and preventing the wire from being directly and messily exposed. The spring 212 maintains a certain degree of openness in its natural state to facilitate wire insertion. When under force and contraction, it can tightly adhere to the wire surface to clamp and fix the wire. Through the cooperation of the internal thread post 213 and the external thread post 214, a lifting structure can be formed, allowing the external thread post 214 to move vertically along the inner wall of the internal thread post 213. The rotating block 215 is a human... When the force input end of the operation is rotated, the rotating block 215 can drive the external threaded column 214 to rotate synchronously, thereby enabling it to move vertically up and down. When the external threaded column 214 moves down, it can squeeze the inclined surface of the single-sided inclined block 216 through the inclined hole 217, converting the vertical force into radial thrust, pushing the spring piece 212 to contract and clamp the wire. Rotating the rotating block 215 in the opposite direction can make the external threaded column 214 move up, releasing the pressure on the single-sided inclined block 216, causing the spring piece 212 to rebound through automatic elastic force, releasing the wire.

[0039] Preferably, multiple spring clips 212 are arranged in a circumferential array on the inner wall of the connector 211;

[0040] After the wire passes through the connector 211, rotating the rotating block 215 drives the external threaded post 214 to rotate, which in turn enables the external threaded post 214 to move vertically along the internal threaded post 213. When the external threaded post 214 moves downward, it can squeeze the single-sided inclined block 216 through the inclined hole 217, thereby causing the single-sided inclined block 216 to drive multiple spring pieces 212 to retract and clamp the wire.

[0041] It should be noted that the distance control mechanism 220 includes a fixed plate 221 fixedly connected to the outer surface of the bracket 110, a threaded rod 222 fixedly installed on the outer surface of the fixed plate 221 by bearings, an internal threaded block 223 threadedly connected to the outer surface of the threaded rod 222, and a sliding plate 224 fixedly connected to the outer surface of the internal threaded block 223.

[0042] Furthermore, the sliding plate 224 is vertically slidably connected to the outer surface of the fixed plate 221;

[0043] When the threaded rod 222 rotates, it can drive the internal threaded block 223 to move the sliding plate 224 vertically.

[0044] Specifically, the distance control mechanism 220 also includes a pitch groove 225 that radially penetrates both sides of the sliding plate 224, a force-bearing column 226 that is movably connected to the inner wall of the pitch groove 225, a sliding rod 227 that is fixedly connected to the outer end face of the force-bearing column 226 and is used to support the wiring pipe 211, and a force-applying end 228 that is fixedly installed on the outer end face of the threaded rod 222.

[0045] It should also be noted that the fixed plate 221 is used to provide an installation base for the distance control mechanism 220. When the threaded rod 222 rotates, it can drive the internal threaded block 223 to drive the sliding plate 224 to move vertically. The variable pitch groove 225 is an inclined groove structure. When the sliding plate 224 moves, it can squeeze the force column 226 through the variable pitch groove 225. The force column 226 converts the vertical thrust into a horizontal thrust, pushing the sliding rod 227 to slide horizontally along the fixed plate 221. This causes the sliding rod 227 to drive the wiring tube 211 to move horizontally synchronously. Finally, multiple sliding rods 227 cooperate with the wiring tube 211 to adjust the uniform distance of multiple wires, so as to facilitate the maintenance of a single wire or improve the space utilization. The force application end 228 is the force input end for manual operation. When it rotates, it drives the threaded rod 222 to rotate.

[0046] Preferably, the sliding rod 227 is horizontally slidably connected to the outer surface of the fixing plate 221, and the fixing plate 221 is fixedly connected to the outer end face of the sliding rod 227;

[0047] When the force-applying end 228 is rotated to drive the threaded rod 222 to move, the threaded rod 222 can drive the sliding plate 224 to move vertically through the internal thread block 223, so that the sliding plate 224 squeezes the force-bearing column 226 through the variable pitch groove 225, and finally drives multiple sliding rods 227 and wiring pipe 211 to move horizontally at a uniform distance.

[0048] When using,

[0049] Multiple external wires connected inside the control box 150 are passed through the wiring slot 160 and inserted into the corresponding wiring pipes 211. Then, the rotating block 215 is rotated to drive the external threaded column 214 to move down along the internal threaded column 213, so that the external threaded column 214 squeezes the single-sided inclined block 216 through the inclined hole 217, which drives the spring piece 212 to retract and clamp the wires.

[0050] Then rotate the force-applying end 228 to drive the threaded rod 222 to rotate, so that the threaded rod 222 drives the internal thread block 223 to drive the sliding plate 224 to move vertically downward along the fixed plate 221, thereby causing multiple variable pitch grooves 225 to simultaneously squeeze multiple force-bearing columns 226, pushing multiple sliding rods 227 to move horizontally closer together, reducing the spacing of the wiring pipes 211, so as to improve space utilization.

[0051] The micro motor to be welded is then fixed in the welding box 120 by the clamp 140, and the welding head 130 is coordinated by the internal program of the control box 150 to weld the motor components according to the preset trajectory, temperature and pressure.

[0052] When a conductor needs maintenance: rotate the force-applying end 228 in the opposite direction to drive the sliding plate 224 to move upward. Through the variable pitch groove 225, the force-bearing column 226 is driven to cause the sliding rod 227 to separate horizontally, thus widening the conductor spacing. Then, rotate the corresponding rotating block 215 in the opposite direction to release the spring piece 212, so that the conductor can be inspected or replaced. After maintenance, the conductor can be re-clamped and the conductor spacing can be reduced to restore operation.

[0053] In summary, by setting the adjustment mechanism 200, it is possible not only to fix multiple external wires during the automatic welding process of micro motors, but also to control the multiple wires to be horizontally close together, reduce the spacing between multiple wires, and avoid the wires being messy and exposed. Furthermore, when a certain wire fails and needs to be repaired, it is possible to expand the spacing between multiple wires and individually release the fixing of the faulty wire. This achieves the effect of improving equipment maintenance efficiency while ensuring the reliability of equipment during use.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
