Description

Technical Field

[0001] The present invention relates to the field of micro-motor processing equipment, and in particular to a micro-motor automatic wire cutting, stripping and welding machine. Background Art

[0002] An electric toy is a motorized toy driven by a micro-motor. The structural performance of the micro-motor affects the performance of the electric toy to a certain extent. As Figure 7 shown, the current micro-motor 200 generally includes a motor body 201, a circuit board 202 and a wire segment 203. Two connection terminals for external electrical connection are provided on the motor body 201. During production, it is necessary to feed the circuit board 202 and the wire segment 203 onto the motor body 201, and then weld the circuit board 202, the wire segment 203 and the connection terminals of the motor body 201 together in pairs. Currently, manual operation is still used when assembling micro-motors. Operators often forget to load the circuit board due to distraction, resulting in unqualified assembly operations of the micro-motors and the need for rework. Moreover, the wire needs to be cut and stripped in advance before welding, and then the wire can be welded. The operation is troublesome and time-consuming. In addition, tin fumes are generated during the welding process, and long-term inhalation of tin fumes causes great harm to the operators.

[0003] Therefore, there is an urgent need for a micro-motor automatic wire cutting, stripping and welding machine that can automatically feed the circuit board and the wire segment, and can also weld the circuit board, the wire segment and the motor body to overcome the above defects. Summary of the Invention

[0004] The purpose of the present invention is to provide a micro-motor automatic wire cutting, stripping and welding machine that can automatically feed the circuit board and the wire segment, and can also weld the circuit board, the wire segment and the motor body.

[0005] To achieve the above purpose, the micro-motor automatic wire cutting, stripping and welding machine of the present invention includes a conveying device and a circuit board feeding device, a wire feeding, cutting and stripping mechanism, and a welding mechanism that are sequentially arranged along the conveying direction of the conveying device. The conveying device is used to convey the motor body. The circuit board feeding device is used to feed the circuit board onto the motor body. The wire feeding, cutting and stripping mechanism is used to feed two parallel and spaced wire segments onto the motor body. The welding mechanism is used to weld the circuit board, the wire segment and the connection terminals of the motor body together in pairs.

[0006] Preferably, the wire feeding, cutting and stripping mechanism includes a wire discharging device, a wire segment processing device and a wire segment handling device. The wire segment processing device is arranged between the wire discharging device and the wire segment handling device. The wire discharging device is used to output wires to the wire segment processing device. The wire segment processing device is used to cut wire segments from the wires and melt and apply solder to the head and tail ends of the wire segments. The wire segment handling device is used to handle the wire segments to the motor body on the conveying device.

The wire gripper is installed at the output end of the rotating driver. The rotating driver drives the wire gripper to rotate. During processing, the wire gripper grips the wire conveyed by the wire discharging device. After the wire segment cutter cuts out a wire segment, the handling feeding driver drives the rotating driver to perform translational movement closer to the conveying device to drive the tail end of the wire segment to move directly above the first heater. After the tail end of the wire segment is soldered, the rotating driver drives the wire gripper to rotate 180°.

The circuit board gripper and the terminal pushing device are respectively installed at the output end of the circuit board picking and placing driver. The circuit board picking and placing driver drives the circuit board gripper and the terminal pushing device to move up and down.

[0013] Preferably, the automatic wire cutting, stripping and welding machine for micro motors of the present invention further includes a flux applying mechanism provided beside the conveying device.

[0023] In order to describe in detail the technical content and structural features of the present invention, the following further description is made in conjunction with the implementation manners and with reference to the accompanying drawings.

[0024] As Figure 1 shown, the micro motor automatic wire cutting, stripping and welding machine 100 of the present invention includes a conveying device 10 and a circuit board feeding device 20, a wire feeding, cutting and stripping mechanism 30, and a welding mechanism 40 that are sequentially arranged along the conveying direction of the conveying device 10. The conveying device 10 is used to convey the motor body 201. The circuit board feeding device 20 is used to feed the circuit board 202 onto the motor body 201. The wire feeding, cutting and stripping mechanism 30 is used to feed two parallel and spaced wire segments 203 onto the motor body 201. The welding mechanism 40 is used to weld the circuit board 202, the wire segments 203 and the connection terminals of the motor body 201 together in pairs. In this way, by using the micro motor automatic wire cutting, stripping and welding machine 100 of the present invention, the circuit board 202 and the wire segments 203 can be automatically fed onto the motor body 201 for welding, and the connection terminals of the circuit board 202, the wire segments 203 and the motor body 201 can be automatically welded together in pairs at one time. Therefore, by using the micro motor automatic wire cutting, stripping and welding machine 100 of the present invention, the qualified rate of product processing can be effectively improved, the production operation is simple and the production efficiency can be improved. It should be noted that when welding, the circuit board 202 is fed onto the motor body 201, and the welding mechanism 40 first welds the circuit board 202 to the motor body 201. Then, two wire segments 203 are fed onto the motor body 201, and each of the two wire segments 203 is lapped on a connection terminal. The welding mechanism 40 welds one of the wire segments 203, a connection terminal of the motor body 201 and the circuit board 202 together, and then the welding mechanism 40 welds the other wire segment 203, the other connection terminal of the motor body 201 and the circuit board 202 together, thus completing the assembly welding of the micro motor 200.

[0025] As Figures 3 to 6As shown, the wire feeding, cutting and stripping mechanism 30 includes a wire discharging device 31, a wire segment processing device 32 and a wire segment handling device 33. The wire segment processing device 32 is arranged between the wire discharging device 31 and the wire segment handling device 33. The wire discharging device 31 is used to output the wire to the wire segment processing device 32. The wire segment processing device 32 is used to cut out the wire segment 203 on the wire and melt and tin the head and tail ends of the wire segment 203. The wire segment handling device 33 is used to handle the wire segment 203 to the motor body 201 on the conveying device 10. In this way, the wire feeding, cutting and stripping mechanism 30 can automatically process the wire segment 203, and can make the two ends of the wire segment 203 melt and tin, improving the degree of automation of production and effectively improving production efficiency. Specifically, the wire segment processing device 32 includes a mounting frame 321, a wire cutter 322, a first heater 323, a second heater 324 and a tinning device 325. The tinning device 325 is mounted on the mounting frame 321. The tinning device 325 has two first tin discharging pipes 3251 and second tin discharging pipes 3252 for outputting tin. The wire cutter 322 is arranged between the first heater 323 and the second heater 324. The first tin discharging pipe 3251 is arranged directly above the first heater 323. The second tin discharging pipe 3252 is arranged directly above the second heater 324. After the wire cutter 322 cuts the wire to form the wire segment 203, the first tin discharging pipe 3251 tins the tail end of the wire segment 203 and the first heater 323 heats the tail end of the wire segment 203. The second tin discharging pipe 3252 tins the head end of the wire and the second heater 324 heats the head end of the wire. In this way, the wire segment processing device 32 can conveniently cut out the wire segment 203. After cutting out the wire segment 203, the tail end of the wire segment 203 and the head end of the wire can be melted and tinned, so that the processing is faster and more coherent, and it is convenient to quickly output the wire segment 203.

[0026] As Figures 3 to 6As shown, the wire segment processing device 32 further includes a first flux feeder 326 and a second flux feeder 327. The first flux feeder 326 is disposed beside the first heater 323, and the second flux feeder 327 is disposed beside the second heater 324. After the wire cutter 322 cuts the wire to form the wire segment 203, the first flux feeder 326 clamps the tail end of the wire segment 203 to apply flux, and the second flux feeder 327 clamps the head end of the wire to apply flux. In this way, it is convenient to apply flux to the tail end of the wire segment 203 by using the first flux feeder 326, and it is also convenient to apply flux to the head end of the wire by using the second flux feeder 327. After applying the flux, then the first solder discharge pipe 3251 applies solder to the tail end of the wire segment 203, and the first heater 323 moves upward to heat the tail end of the wire segment 203, so that the tail end of the wire segment 203 melts and is soldered. The second solder discharge pipe 3252 applies solder to the head end of the wire, and the second heater 324 moves upward to heat the head end of the wire, so that the head end of the wire melts and is soldered. Preferably, when the first flux feeder 326 applies flux to the tail end of the wire segment 203, it is located directly above the first heater 323, and when the second flux feeder 327 applies flux to the head end of the wire, it is located directly above the second heater 324. After applying the flux, the first flux feeder 326 and the second flux feeder 327 move away. The first heater 323 and the second heater 324 move upward to heat the tail end of the wire segment 203 and the head end of the wire. In this embodiment, the first flux feeder 326 and the second flux feeder 327 clamp the tail end of the wire segment 203 and the head end of the wire by horizontal translation to apply flux. To conveniently display the processing flow of the wire feeding, cutting, and stripping mechanism 30 and the welding mechanism 40 of the present invention for processing the wire segment, in Figure 6 In steps 2-4, the first flux feeder 326 and the second flux feeder 327 move upward to move away from the flux application position, but it should actually be understood that the first flux feeder 326 and the second flux feeder 327 move away from the flux application position by moving horizontally outward or inward along the paper surface.

[0027] As Figures 3 to 6As shown, the wire segment handling device 33 includes a handling driver 331, a handling carry driver 332, a rotation driver 333, and a wire gripper 334. The handling driver 331 is installed on the mounting frame 321. The handling carry driver 332 is installed at the output end of the handling driver 331. The handling driver 331 drives the handling carry driver 332 to perform translational movement back and forth between the conveying device 10 and the wire segment processing device 32. The rotation driver 333 is installed at the output end of the handling carry driver 332. The handling carry driver 332 drives the rotation driver 333 to perform translational movement closer to or farther away from the conveying device 10. The wire gripper 334 is installed at the output end of the rotation driver 333. The rotation driver 333 drives the wire gripper 334 to rotate. During processing, the wire gripper 334 grips the wire conveyed by the wire discharging device 31. After the wire segment cutter 322 cuts out the wire segment 203, the handling carry driver 332 drives the rotation driver 333 to perform translational movement closer to the conveying device 10 to drive the tail end of the wire segment 203 to move directly above the first heater 323. After the rotation driver 333 solders the tail end of the wire segment 203, it drives the wire gripper 334 to rotate 180°. The handling driver 331 drives the rotation driver 333 to perform translational movement closer to the conveying device 10 to drive the tail end of the wire segment 203 held by the wire gripper 334 to be placed on the motor body 201. After the wire segment cutter 322 cuts the wire to form the wire segment 203, the handling carry driver 332 drives the rotation driver 333 to move closer to the conveying device 10 to make the tail end of the wire segment 203 move directly above the first heater 323, so as to facilitate applying flux and melting solder on the tail end of the wire segment 203. After the wire gripper 334 grips the wire, the positioning between the two wires is completed. After the two wire segments 203 are flipped 180°, the tail end of the wire segment 203 is lapped on the terminal on the motor body 201, which is convenient for quick and accurate welding.

[0028] As Figures 3 to 6As shown, the wire discharging device 31 includes a wire carrying wheel frame 311, a loading driver 312 and an ejection driver 313. The wire carrying wheel frame 311 is slidably installed. Each of the wire carrying wheel frames 311 is installed at the output ends of the loading driver 312 and the ejection driver 313. The loading driver 312 drives the wire carrying wheel frame 311 to move closer to or away from the second heater 324. The ejection driver 313 drives the wire carrying wheel frame 311 to move away from the second heater 324. The wire carrying wheel frame 311 is used to carry the electric wire and output the electric wire to the wire gripper 334. When the electric wire is conveyed to the wire gripper 334, the ejection driver 313 drives the wire carrying wheel frame 311 to slide away from the second heater 324 to release the electric wire. When the wire cutter 322 cuts the electric wire, the ejection driver 313 drives the wire carrying wheel frame 311 to move backward to strip the head end of the electric wire and the tail end of the wire segment 203. In this way, the wire discharging device 31 can automatically and conveniently feed the electric wire to the wire segment processing device 32. Moreover, after the wire cutter 322 cuts the electric wire to obtain the wire segment 203, the head end of the electric wire and the tail end of the wire segment 203 can also be stripped to expose the metal core, facilitating the subsequent soldering operation.

[0029] As Figure 1 shown, the welding mechanism 40 includes a welding driving device 41 and a welding torch 42. The welding driving device 41 is installed on the mounting frame 321, and the welding torch 42 is installed at the output end of the welding driving device 41. The welding driving device 41 drives the welding torch 42 to perform three-axis translation movement. The structure of the welding mechanism 40 is simple and easy to install and arrange. It is beneficial for the welding driving device 41 to drive the welding torch 42 to move to the welding position. The welding driving device 41 driving the welding torch 42 to perform three-axis translation movement means that the welding driving device 41 drives the welding torch 42 to perform translation movement along the X, Y, and Z directions, but is not limited thereto. To facilitate the unloading of the motor after welding, the automatic wire cutting, stripping and welding machine 100 for micro motors of the present invention further includes a motor unloading mechanism 50 provided beside the end of the conveying device 10. The motor unloading mechanism 50 removes the welded micro motor 200 from the conveying device 10.

[0030] As Figure 1 and Figure 2As shown, the circuit board loading device 20 includes an assembly frame 21, a circuit board handling driver 22, a circuit board picking and placing driver 23, a circuit board gripper 24 and a terminal pusher 25. The assembly frame 21 is installed above the conveying device 10. The circuit board handling driver 22 is installed on the assembly frame 21. The circuit board picking and placing driver 23 is horizontally slidably assembled on the assembly frame 21. The circuit board handling driver 22 drives the circuit board picking and placing driver 23 to slide closer to or away from the conveying device 10. The circuit board gripper 24 and the terminal gripper 25 are respectively installed at the output end of the circuit board picking and placing driver 23. The circuit board picking and placing driver 23 drives the circuit board gripper 24 and the terminal pusher 25 to move up and down. The circuit board gripper 24 can pick up the circuit board 202. After the circuit board gripper 24 places the picked-up circuit board 202 on the motor body 201, the terminal pusher 25 pushes the two terminals on the motor body 201 outwards, so that the two terminals are bent and crimped on the circuit board 202, facilitating the welding of the circuit board 202, the terminals of the motor body 201 and the wire segment 203 together. To strengthen the welding firmness between the circuit board 202 and the motor body 201, the micro motor automatic wire cutting, stripping and welding machine 100 of the present invention further includes a fluxing agent mechanism (not shown in the figure) provided beside the conveying device 10. The fluxing agent mechanism (not shown in the figure) applies flux to the circuit board 202 after the circuit board loading device 20 loads the circuit board 202 onto the motor body 201 and pushes the two terminals of the motor body 201. Preferably, the fluxing agent mechanism applies flux to the circuit board 202 by pressing a pressing head adhered with flux on the circuit board 202, but it is not limited thereto. For example, the terminal pusher 25 uses the two clamping fingers of a clamping finger cylinder to open outwards to push the two terminals, but it is not limited thereto.

[0031] Combined with the attached Figures 1 to 7 , the working principle of the micro motor automatic wire cutting, stripping and welding machine 100 of the present invention is described as follows: The conveying device 10 conveys the motor body 201 along its conveying direction. After the circuit board gripper 24 picks up a circuit board 202, the circuit board picking and placing driver 23 drives the circuit board gripper 24 to move upwards. The circuit board handling driver 22 drives the picking and placing driver 23 to slide closer to the conveying device 10, driving the circuit board gripper 24 to move to directly above a motor body 201. The circuit board picking and placing driver 23 drives the circuit board gripper 24 to move downwards, and the circuit board gripper 24 places the picked-up circuit board 202 on the motor body 201. The terminal pusher 25 pushes the two terminals on the motor body 201. Then, the fluxing agent mechanism applies flux to the circuit board 202.

[0032] Then, as Figure 6 and Figure 7As shown, when the motor body 201 is conveyed to the side of the wire feeding, cutting and stripping mechanism 30, the feeding driver 312 drives the wire carrying wheel frame 311 to move closer to the conveying device 10. The wire at the output end of the wire carrying wheel frame 311 is sent into the wire gripper 334. The wire gripper 334 grips the wire, and the retracting driver 313 drives the wire carrying wheel frame 311 to move away from the conveying device 10 to release a section of wire. Then, the wire cutter 322 cuts the wire to form a wire segment 203. At the same time, the retracting driver 313 continues to drive the wire carrying wheel frame 311 to move away from the conveying device 10, so that the tail end of the wire segment 203 and the head end of the wire are stripped. Then, the handling and feeding driver 332 drives the rotating driver 333 to move closer to the conveying device 10, so that the tail end of the wire segment 203 reaches directly above the first heater 323. The first flux feeder 326 grips the tail end of the wire segment 203, and the second flux feeder 327 grips the head end of the wire, so as to apply flux to the tail end of the wire segment 203 and the head end of the wire. The first flux feeder 326 and the second flux feeder 327 move away. The first heater 323 and the second heater 324 move upward. The first solder discharge pipe 3251 applies solder to the tail end of the wire segment 203, and the second solder discharge pipe 3252 applies solder to the head end of the wire. The first heater 323 heats the tail end of the wire segment 203 to melt and apply the solder, and the second heater 324 heats the head end of the wire to melt and apply the solder. Then, the rotating driver 333 drives the wire gripper 334 to rotate 180°. At the same time, the handling driver 331 drives the handling and feeding driver 332 to move closer to the conveying device 10, so that the tail end of the wire segment 203 is lapped on the wiring terminal of the motor body 201. The welding driving device 41 drives the welding torch 42 to move above the motor body 201, and the welding torch 42 welds the motor body 201, the circuit board 202 and the wire segment 203 together in pairs, thus completing the welding of the micro-motor 200. When the conveying device 10 conveys the micro-motor 200 to the motor discharging mechanism 50, the motor discharging mechanism 50 discharges the micro-motor 200. In this way, the above processing process is repeated to facilitate the continuous processing of the micro-motor 200, and the working principle is as described above.

[0033] Compared with the prior art, the automatic wire cutting, stripping and welding machine 100 for micro motors of the present invention includes a conveying device 10, a circuit board loading device 20, a wire feeding, cutting and stripping mechanism 30 and a welding mechanism 40 which are sequentially arranged along the conveying direction of the conveying device 10. The conveying device 10 is used for conveying the motor body 201. The circuit board loading device 20 is used for loading the circuit board 202 onto the motor body 201. The wire feeding, cutting and stripping mechanism 30 is used for loading two parallel and spaced wire segments 203 onto the motor body 201. The welding mechanism 40 is used for welding the circuit board 202, the wire segments 203 and the connection terminals of the motor body 201 together in pairs. In this way, by using the automatic wire cutting, stripping and welding machine 100 for micro motors of the present invention, the circuit board 202 and the wire segments 203 can be automatically loaded onto the motor body 201 for welding, and the connection terminals of the circuit board 202, the wire segments 203 and the motor body 201 can be welded together in pairs automatically at one time. Therefore, by using the automatic wire cutting, stripping and welding machine 100 for micro motors of the present invention, the qualified rate of product processing can be effectively improved, the production operation is simple and the production efficiency can be improved.

[0034] The above-disclosed are only the preferred examples of the present invention, and the scope of the rights of the present invention cannot be limited thereby. Therefore, all equivalent changes made according to the claims of the present invention fall within the scope covered by the present invention.
