[0002] With improved living standards, electric toys have gradually become the mainstream in the toy market, and various toy designs can be made into electric toys. A toy motor is a small electric motor used in toys, mainly to provide power and motion effects. Toy motors have low power and voltage. A toy motor consists of a motor body, a gear needs to be installed on the output shaft of the motor body, and end caps, circuit boards, and other components need to be installed on the motor body before wiring is done.

[0003] In existing technologies, gears are typically pre-installed on the motor's output shaft manually, followed by the installation of the end cover, then the circuit board, and finally, the positive and negative wires and grounding point on the motor are manually soldered. However, because toy motors are small, and components such as gears, end covers, and circuit boards are also small, manual assembly and alignment are cumbersome and unreliable, presenting assembly difficulties and easily leading to assembly defects. Furthermore, some existing motor assembly and welding equipment cannot directly assemble individual components; they generally require separate assembly on different equipment followed by wire soldering, resulting in cumbersome operations and complex structures.

[0004] Therefore, it is necessary to provide a motor assembly and wire bonding equipment that can automatically feed and assemble materials, automatically bond wires, and is easier to operate. Utility Model Content

[0041] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0042] Please see Figure 1This utility model provides a motor assembly and wire bonding equipment 100, applicable to the automatic assembly and wire bonding of motors. The motor assembly and wire bonding equipment 100 includes a frame 101 and motor feeding device 102, gear feeding device 103, end cap feeding device 104, and circuit board feeding device 105 disposed around the frame 101. The motor feeding device 102 is a lifting feeding device used for feeding the motor body 1001. The gear feeding device 103 is a vibratory feeder automatic feeding device used for automatically feeding gear components 1002. The end cap feeding device 104 is a vibratory feeder automatic feeding device used for automatically feeding end cap components 1003.

Furthermore, a turntable mechanism 106 is provided on the frame 101, and multiple feeding fixtures 1060 are evenly distributed along the circumference at preset intervals on the turntable mechanism 106. Along the periphery of the turntable mechanism 106 on the frame 101, a material handling device 10, a first assembly device 20, a second assembly device 30, a third assembly device 40, a first welding device 50, a second welding device 60, a third welding device 80, and a fourth welding device 90 are arranged sequentially according to the processing sequence. Specifically, the gear feeding device 103 feeds the gear component 1002 onto the first assembly device 20. The material handling device 10 picks up the motor body 1001 from the motor feeding device 102 and places it on the first assembly device 20 to engage with the gear component 1002. Then, the gear component 1002 and the motor body 1001 are assembled together. Subsequently, the first assembly device 20 places the motor body 1001 with the gear component 1002 assembled into a feeding fixture 1060 at a preset position on the turntable mechanism 106. The preset position is the position on the turntable mechanism 106 closest to the feeding fixture 1060 of the first assembly device 20 after each rotation of the turntable mechanism 106. The second assembly device 30 is used to assemble the end cap 1003, fed from the end cap feeding device 104, onto the motor body 1001. The third assembly device 40 is used to assemble the circuit board 1004, fed from the circuit board feeding device 105, onto the motor body 1001 and form a motor assembly. The first welding device 50 is used to weld the positive wire onto the motor assembly. The second welding device 60 is used to weld the negative wire onto the motor assembly; the third welding device 80 is used to weld one end of the ground wire onto the motor assembly. The fourth welding device 90 is used to weld the other end of the ground wire onto the motor assembly.

[0043] By adopting the above technical solution, the motor assembly and wire bonding equipment 100 of this utility model can automatically feed the gear component 1002, end cover component 1003, and circuit board 1004 and automatically assemble them with the motor body 1001 to form a motor assembly. It can also automatically weld the positive wire, negative wire, and ground wire onto the circuit board 1004 of the motor assembly. The assembly and wire bonding equipment of this utility model has a reasonable structural layout, a high degree of automation, and greatly improves production efficiency.

[0044] Please see Figures 1 to 3 In some optional embodiments, the first assembly device 20 includes a pressing assembly mechanism 21. The pressing assembly mechanism 21 has an assembly position 211, and a pressing component 212 is disposed above the assembly position 211. The assembly position 211 is connected to a gear feeding device 103, which automatically feeds the gear component 1002 to the assembly position 211. Then, the picking device 10 picks up the motor body 1001, places it on the assembly position 211, aligns it with the gear component 1002, and the pressing component 212 presses the motor body 1001 and the gear component 1002 together. The picking device 10 is a robotic arm picking device 10. Understandably, the gear component 1002 is automatically fed into the assembly station 211 and positioned within the assembly station 211. The output shaft of the motor body 1001 is aligned with the gear component 1002 at the assembly station 211, and then the material is pressed from top to bottom by the pressing assembly 212 so that the output shaft passes through the gear component 1002, thereby installing the motor body 1001 and the gear component 1002 together.

[0045] Please see Figures 1 to 3 In some optional embodiments, the first assembly device 20 further includes a correction mechanism 22 and a first material handling mechanism 23. Two lugs are provided on the motor body 1001 for the end cap 1003 to pass through, and the lugs can mate with the end cap 1003 and the circuit board 1004. However, during transportation or assembly, the lugs may be touched, causing them to tilt, which affects the alignment and installation of the lugs with the end cap 1003. Specifically, the correction mechanism 22 includes a feeding assembly 221 and a correction assembly 222. The correction assembly 222 is located on one side of the feeding assembly 221. The material handling device 10 places the motor body 1001, on which the gear component 1002 is mounted, onto the feeding assembly 221, and the correction assembly 222 passes between the two lugs to correct the two lugs to a preset state. The calibration assembly 222 includes a calibration member 2221, which pre-contacts one end of the lug and has a gradually increasing structure. This allows the calibration member 2221 to slowly align the two lugs as it passes between them, facilitating their engagement with the end cap 1003 in subsequent processes. A detection mechanism 24 is also provided on one side of the calibration mechanism 22 to detect the calibration result of the lugs on the motor body 1001. Meanwhile, the first material handling mechanism 23 picks up the calibrated motor body 1001 from the material handling assembly 221 and places it into the material handling fixture 1060 at a preset position on the turntable mechanism 106. The preset position is the position on the turntable mechanism 106 closest to the first assembly device 20 after each rotation of the turntable mechanism 106. The turntable mechanism 106 rotates to rotate the motor body 1001 to the second assembly device 30.

[0046] Please see Figures 4 to 6In some optional embodiments, the second assembly device 30 includes a first pushing component 31, a first pre-positioning fixture 32, a second picking mechanism 33, and a pressing mechanism 34. The end cap feeding device 104 is connected to the first pre-positioning fixture 32, and automatically feeds the end cap 1003 onto the material channel. The first pushing component 31 is located between the end cap feeding device 104 and the first pre-positioning fixture 32, and is used to push the end cap 1003 onto the first pre-positioning fixture 32. Specifically, the first pre-positioning fixture 32 includes a pre-positioning material position 322, one end of which is provided with a pushing plate 321. The pushing plate 321 is connected to a pushing cylinder 323, which actuates to push the pushing plate 321 to push the end cap 1003 into the pre-positioning material position 322 for pre-positioning, so as to pick up the material. The second material handling mechanism 33 picks up the end cap 1003 from the first prepositioning fixture 32 and places it into the unloading fixture 1060 to cooperate with the motor body 1001. The unloading fixture 1060 includes a material trough 1061 for unloading, and clamping jaws 1062 are provided on both sides of the material trough 1061 for clamping. The two clamping jaws 1062 are connected to a clamping cylinder 1063. The clamping cylinder 1063 is activated to simultaneously drive the clamping jaws 1062 on both sides to clamp the motor body 1001 in the material trough 1061, so as to position the motor body 1001 in the unloading fixture 1060 for subsequent assembly. On the other hand, the pressing mechanism 34 is located on the side of the first prepositioning fixture 32 near the third assembly device 40. The turntable mechanism 106 rotates to drive the motor body 1001, on which the end cap 1003 is placed, to rotate to the pressing mechanism 34. The pressing mechanism 34 operates to press the end cap 1003 onto the motor body 1001.

[0047] Please see Figure 7 In some optional embodiments, the third assembly device 40 includes a second pushing component 41, a second pre-positioning fixture 42, and a picking and pressing mechanism 43. The circuit board loading device 105 is connected to the second pre-positioning fixture 42 and can automatically load the circuit board 1004 onto a surface close to the second pre-positioning fixture 42. The second pushing component 41 is located between the circuit board loading device 105 and the second pre-positioning fixture 42. The second pushing component 41 pushes the circuit board 1004 from the material channel of the circuit board loading device 105 onto the second pre-positioning fixture 42 for pre-positioning, enabling better alignment and material picking for subsequent assembly processes. On the other hand, the picking and pressing mechanism 43 picks up the circuit board 1004 from the second pre-positioning fixture 42, places the circuit board 1004 into the unloading fixture 1060 to cooperate with the motor body 1001, and presses the circuit board 1004 onto the motor body 1001 to form a motor assembly.

[0048] Please see Figure 1 and Figure 8In some optional embodiments, the first welding device 50 includes a first welding mechanism 51, a first wire feeding and stripping mechanism 52, a first wiring mechanism 53, and a solder pot feeding mechanism 54. The first welding mechanism 51 is vertically mounted on one side of the turntable mechanism 106, and the first wiring mechanism 53 is located between the first wire feeding and stripping mechanism 52 and the turntable mechanism 106. The first wire feeding and stripping mechanism 52 feeds the positive wire and cuts it to a first preset length, stripping the end of the positive wire. The first preset length is a suitable length for the positive wire. The first wiring mechanism 53 feeds the cut positive wire from the first wire feeding and stripping mechanism 52 to a corresponding feeding fixture 1060 to cooperate with the motor assembly. The other end of the positive wire is soldered on the solder pot feeding mechanism 54. The first welding mechanism 51 welds one end of the positive wire to the circuit board 1004 of the motor assembly. On the other hand, the second welding device 60 has the same structure as the first welding device 50. The second welding device 60 includes a second welding mechanism, a second wire feeding and stripping mechanism, a second wiring mechanism, and a solder pot feeding mechanism 54. The second welding mechanism is vertically mounted on one side of the turntable mechanism 106, and the second wiring mechanism is located between the second wire feeding and stripping mechanism and the turntable mechanism 106. The second wire feeding and stripping mechanism feeds the negative wire and cuts and strips it to a first preset length, which is a suitable length for the negative wire. The second wiring mechanism is used to feed the negative wire cut by the second wire feeding and stripping mechanism to the corresponding feeding fixture 1060 to cooperate with the motor assembly. The second welding mechanism welds the negative wire to the motor assembly.

[0049] Specifically, the wire feeding and stripping mechanism includes a wire feeding assembly and a wire cutting and stripping assembly. The wire feeding assembly conveys the positive or negative wire, while the wire cutting and stripping assembly, located to one side of the wire feeding assembly, cuts and strips the wire. A waste trough for receiving the wire sheath can also be provided to one side of the wire cutting and stripping assembly. The wiring mechanism includes a guiding and conveying assembly and two sets of wiring assemblies. Each set of wiring assemblies includes a first wiring component and a second wiring component. The guiding and conveying assembly is located between the first and second wiring components. The guiding and conveying assembly operates to convey the positive or negative wire from the first wiring component to the second wiring component. Specifically, the guiding and conveying assembly includes a first guide wheel and a second guide wheel. The first guide wheel is located above the second guide wheel, and the positive or negative wire passes between the first and second guide wheels. The rotation of the first and second guide wheels drives the positive or negative wire from the first wiring component to the second wiring component. The second wiring component has a gradually decreasing cross-sectional area from the end closest to the first wiring component to the end furthest from the first wiring component. The smaller end of the second wiring component allows for better alignment and soldering. The solder pot feeding mechanism 54 includes a soldering component. The soldering component is located on one side of the wire feeding and stripping mechanism, and one end of the cut positive or negative wire is soldered inside the soldering component. The soldering component is capable of vertical movement.

[0050] Please see Figure 9 In some optional embodiments, a rotating mechanism 70 is further provided between the second welding device 60 and the third welding device 80. The motor assembly exits from the second welding device 60, and the positive and negative wires on the motor assembly have already been welded. In the previous process, the motor assembly is placed in a certain position within the feeding fixture 1060 for ease of assembly and welding. To facilitate the ground wire welding in the next process, the position of the motor assembly needs to be adjusted. The rotating mechanism 70 includes a rotating gripper 71 and a rotating cylinder 72. The rotating cylinder 72 actuates to drive the rotating gripper 71 to pick up the material within the feeding fixture 1060 and rotate it by a certain angle, and then release the material away from the feeding fixture 1060.

[0051] Please see Figure 10 In some optional embodiments, the third welding device 80 includes a third welding mechanism 81, a wire feeding mechanism 82, a guiding mechanism 83, and a wire cutting mechanism 84. The wire feeding mechanism 82 is used to feed a ground wire, which can be an iron wire. The guiding mechanism 83 is movably disposed between the wire feeding mechanism 82 and the turntable mechanism 106, and can slide between the wire feeding mechanism 82 and the turntable mechanism 106 to feed the ground wire onto the unloading fixture 1060 of the turntable mechanism 106 for alignment with the motor assembly. The guiding mechanism 83 is provided with a wire feeding member 831 through which the ground wire passes. The wire feeding member 831 has a gradually decreasing cross-sectional area from the end away from the turntable mechanism 106 to the end near the turntable mechanism 106, so that the ground wire in the wire feeding member 831 can be better aligned and welded with the motor assembly on the unloading fixture 1060. The wire feeding member 831 is mounted on a sliding assembly 832 and slides through the sliding assembly 832 to move closer to or away from the motor assembly. The ground wire passes through the wire feeding member 831 of the guide mechanism 83 and engages with the motor assembly on the feeding fixture 1060. The cutting member 841 on the wire cutting mechanism 84 cuts the ground wire to a second preset length, which is a suitable length for the ground wire. The cutting member 841 is movable up and down, and the two cutting clamps can move closer and further apart to cut the ground wire. The third welding mechanism 81 operates to weld one end of the ground wire to the circuit board 1004 of the motor assembly.

[0052] Please see Figure 11 and Figure 12In some optional embodiments, the fourth welding device 90 includes a feeding and positioning mechanism 91, and a third picking mechanism 92, a grinding mechanism 93, a fourth welding mechanism 94, and a unloading mechanism 95 located on the side of the feeding and positioning mechanism 91. The third picking mechanism 92 is used to place the motor assembly with the ground wire welded onto the feeding and positioning mechanism 91 and rotate the motor assembly by a preset angle. The third picking mechanism 92 can pick up the motor assembly and rotate it from a vertical position to a horizontal position. Then, the grinding mechanism 93 grinds a welding position on the outer shell of the motor body 1001, and the fourth welding mechanism 94 actuates to weld the other end of the ground wire to the welding position. Specifically, the feeding and positioning mechanism 91 includes a feeding and positioning fixture 911 and a positioning component 912. The feeding and positioning fixture 911 is provided with a feeding position 9111 and clamping components 9112 located on both sides of the feeding position 9111. The third material handling mechanism 92 picks up the motor assembly from the feeding fixture 1060, rotates it by a preset angle, and places it in the feeding position 9111. In this embodiment, the preset angle is 90°, that is, rotating the motor assembly from a vertical position to a horizontal position to allow operation on the side of the motor body 1001. After the motor assembly is placed in the feeding position 9111, the clamping component 9112 actuates to clamp and position the motor assembly from both sides, exposing the side of the motor body 1001 for grinding. On the other hand, the positioning component 912 includes a bending member 9121, which bends the ground wire to the other end at the welding position. The bending member 9121 is L-shaped and can slide back and forth on the frame 101. Since one end of the ground wire is welded to the circuit board 1004 of the motor assembly, and the other end protrudes from the circuit board 1004.
