[0029] Figure 9 A schematic diagram of the structure for mounting wire guides and terminals on the motor body. Detailed Implementation

[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0031] like Figures 1 to 6 As shown, a motor terminal assembly device includes a machine base 11, a wire guide frame mounting device 20, and a terminal mounting device 30 mounted on the machine base 11. The wire guide frame mounting device 20 includes a first positioning mechanism 21 and a hot riveting mechanism 22. The first positioning mechanism 21 is used to support and position the motor body. The hot riveting mechanism 22 includes a first lifting drive unit 221 and a hot riveting assembly 222 disposed at the output end of the first lifting drive unit 221. The first lifting drive unit 221 is mounted on a vertical plate 200 located on the machine base 11. The hot riveting assembly 222 is driven by multiple hot riveting heads 2220 at its lower part to abut against the pins on the motor body to melt the pins. The column is used to fix the wire guide frame sleeved on the pin column. The terminal mounting device 30 includes a rotary table 31, a second positioning mechanism 32, a frame 300, a terminal insertion mechanism 33 and a detection mechanism 34. A pair of second positioning mechanisms 32 are disposed on the rotary table 31. The terminal insertion mechanism 33 is disposed on the frame 300 and is adjacent to the detection mechanism 34. The terminal insertion mechanism 33 includes a second lifting drive unit 331 and a pressure head 332 disposed at the output end of the second lifting drive unit 331. The pressure head 332 is driven to move down to press the terminal located in the mounting hole on the wire guide frame. The detection mechanism 34 is used to detect the depth of the terminal pressed into the mounting hole.

[0032] Combination Figure 9As shown, the objects to be assembled in this utility model are a motor body 101, a wire guide 102, and terminals 103. The motor body 101 has multiple pins 1011, and the wire guide 102 has mounting holes that match the pins 1011 and mounting insertion holes 1021 for pressing in the terminals 103. During the assembly process, the wire guide 102 needs to be installed on the motor body 101 so that the mounting holes fit onto the pins 1011. The upper part of the pins 1011 is then melted to fix the wire guide 102 to the motor body 101. Then, multiple terminals 103 are pressed into the mounting insertion holes 1021 to complete the assembly of the motor body 101, the wire guide 102, and the terminals 103. Specifically, the motor body 101 can be manually positioned on the first positioning mechanism 21. A wire guide frame 102 is installed on the motor body 101. The first positioning mechanism 21 feeds the motor body 101 to the hot riveting mechanism 22. The first lifting drive unit 221 can be an electric cylinder, which drives the hot riveting assembly 222 downwards. The hot riveting assembly 222 is a combination of a heater and hot riveting heads 2220. The number of hot riveting heads 2220 is the same as the number of pins 1011. The hot riveting heads 2220 abut against the pins 1011, melting the upper part of the pins 1011 through heating. The molten pins spread out and adhere to the wire guide frame 102 at a position next to the mounting hole, thereby fixing the wire guide frame 102 to the motor body 101. After completing the above actions, the hot riveting mechanism 22 and the first positioning mechanism 21 respectively... The motor body 101 is manually moved from the first positioning mechanism 21 and positioned on the second positioning mechanism 32. The second positioning mechanism 32 is driven by the rotary table 31 to move below the terminal insertion mechanism 33. The lower end of the terminal 103 is inserted into the mounting hole 1021 on the wire guide frame 102 by manual feeding. The terminal insertion mechanism 33 is set on the frame 300. Its second lifting drive unit 331 can be an electric cylinder. The second lifting drive unit 331 drives the pressure head 332 to move down to press the terminal 103 in the mounting hole 1021, thereby completing the assembly of the motor 101, the wire guide frame 102 and the terminal 103. The second positioning mechanism 32 is moved to the side of the detection mechanism 34 by the rotary table 31. The detection mechanism 34 is used to detect the depth of the terminal 103 pressed into the mounting hole 1021.

[0033] This utility model uses a first positioning mechanism 21 to position the motor body 101 and a hot riveting mechanism 22 to assemble the wire guide frame 102 with the motor body 101. The rotating table 31, the second positioning mechanism 32 and the terminal insertion mechanism 33 cooperate to install the terminal 103 into the mounting hole 1021 on the wire guide frame 102. The detection mechanism 34 detects the installation of the terminal 103. This allows for precise assembly of the motor body 101, the wire guide frame 102 and the terminal 103, and improves assembly efficiency.

[0034] Preferred, such as Figure 3 As shown, the first positioning mechanism 21 includes a translation drive unit 211 and a first positioning fixture 212. The translation drive unit 211 can be an electric cylinder and is mounted on the machine base 11. The first positioning fixture 212 is slidably mounted on the machine base 11 via a guide rail pair and is connected to the output end of the translation drive unit 211. When manually loading the motor body 101, the first positioning fixture 212 is located away from the hot riveting mechanism 22. The motor body 101 is placed on the first positioning fixture 212, and the wire guide frame 102 is placed on the motor body 101. The translation drive unit 211 drives the first positioning fixture 212 and the motor body 101 on it to move below the hot riveting mechanism 22. After the hot riveting action is completed, the translation drive unit 211 drives the first positioning fixture 212 and the motor body 101 on it to reset, and the manual unloading is performed. Therefore, manual operation can be performed away from the hot riveting mechanism 22, ensuring operational safety.

[0035] like Figure 4 and Figure 5 As shown, the hot riveting mechanism 22 is also provided with a pressing component 23. The pressing component 23 includes a fixed plate 231, a movable rod 232, a pressure plate 233 and a spring 234. The fixed plate 231 is fixedly disposed on the upper part of multiple hot riveting heads 2220, and the fixed plate 231 has a guide through hole (not shown) that penetrates vertically through its body. The movable rod 232 is disposed in the guide through hole and can slide up and down. The spring 234 connects the upper end of the movable rod 232 and the hot riveting component 222. The pressure plate 233 is disposed at the lower end of the movable rod 232 for pressing down the wire guide 102 located on the motor body 101. The pressure plate 233 is located at the lower end of the movable rod 232 and below the hot riveting head 2220. When the pin 1011 on the motor body 101 needs to be hot riveted, the pressure plate 233 first abuts against the wire guide 102 when the hot riveting assembly 222 is driven to move downward, which can press the wire guide 102 onto the motor body 101. Since the upper end of the movable rod 232 is connected to the hot riveting assembly 222 through the spring 234, the movable rod 232 can move up and down relative to the hot riveting assembly 222. When the pressure plate 233 presses the wire guide 102, the hot riveting assembly 222 continues to move downward, so that the hot riveting head 2220 abuts against the pin 1011 to perform the hot riveting action. After the hot riveting action is completed, in the initial stage when the hot riveting assembly 222 is driven to move upward, the pressure plate 233 still abuts against the wire guide 102 to maintain a certain downward pressure, which can ensure the assembly stability of the wire guide 102 and the motor body 101.

[0036] Furthermore, the upper end of the movable rod 232 is provided with a limiting ring 2321. The limiting ring 2321 cannot pass downward through the guide hole. After it moves downward, it can abut against the fixed plate 231 to limit the downward movement distance of the movable rod 232. Preferably, slots can be provided at the upper end of the movable rod 232 and at the position on the hot riveting assembly 222 where it abuts against the spring 234, to respectively position the lower and upper ends of the spring 234, thus ensuring the position of the spring 234. The pressure plate 233 is provided with multiple clearance notches 2330 opposite to the position of the hot riveting head 2220. Since the pressure plate 233 has a large range for covering the wire guide frame 102 to ensure the stability of pressing down on the wire guide frame 102, the clearance notches 2330 can avoid interference with the pin 1011, and also allow the hot riveting head 2220 to extend into the clearance notches 2330 and abut against the pin 1011.

[0037] Preferred, such as Figure 6 As shown, in the terminal insertion mechanism 33, the pressure head 332 is connected to the guide rod 3341. The frame 300 is provided with a guide cylinder 3342. The guide rod 3341 can slide up and down in the guide cylinder 3342. The cooperation between the guide rod 3341 and the guide cylinder 3342 can ensure the accuracy and stability of the downward movement of the pressure head 332, which makes it easy to accurately press the terminal 103 into the mounting hole 1021.

[0038] Furthermore, the terminal insertion mechanism 33 also includes an auxiliary positioning assembly, which includes a downward drive unit (not shown), a base plate 3000, a slide plate 3331, and a horizontal plate 3332. The downward drive unit can be an electric cylinder, and both it and the base plate 3000 are mounted on the frame 300. The slide plate 3331 is vertically slidable on the base plate 3000 via a guide rail pair and is connected to the output end of the downward drive unit. The horizontal plate 3332 is mounted on the slide plate 3331 and has a guide hole 3330 through its body for the terminal 103 to pass through. When the rotary table 31 drives the motor body 101 located in the second positioning mechanism 32 to be below the pressure head 332, the downward drive unit drives the slide plate 3331 to move the horizontal plate 3332 above the motor body 101. The guide hole 3330 on 3332 corresponds to the mounting hole 1021 on the wire guide 102 on the motor body 101. The terminal 103 is manually inserted into the guide hole 3330 from top to bottom, so that the lower part of the terminal 103 is embedded in the mounting hole 1021. Then, the second lifting drive unit 331 drives the pressure head 332 to move down and abut against the terminal 103, pressing the terminal 103 into the mounting hole 1021. The guide hole 3330 limits the terminal 103 to ensure that the terminal 103 moves vertically, which is more conducive to accurately pressing the terminal 103 into the mounting hole 1021. After the terminal 103 is pressed in, the downward drive unit drives the slide plate 3331 to move the horizontal plate 3332 up, so that the guide hole 3330 moves upward and disengages from the terminal 103.

[0039] like Figure 7 As shown, the detection mechanism 34 includes a third lifting drive unit 341, a mounting plate 340, and a displacement sensor 342. The third lifting drive unit 341 can be an electric cylinder, which is preferably set on the machine base 11, and the output end is provided with a mounting plate 340. Multiple displacement sensors 342 are set on the mounting plate 340 to detect the pressing depth of multiple terminals 103 respectively. When the terminal 103 is pressed into the mounting hole 1021 of the wire guide frame 102 by the pressing head 332, the rotary table 31 drives the second positioning mechanism 32 and the motor body 101 located thereon to move to below the displacement sensor 342. The third lifting drive unit 341 drives the displacement sensor 342 to move down and abut against the upper end of the terminal 103 to detect whether the terminal 103 is pressed into place.

[0040] Two second positioning mechanisms 32 are provided, forming a dual-station operation, which can realize simultaneous feeding and pressing, as well as pressing and inspection, thereby improving operational efficiency. The second positioning mechanism 32 includes a second positioning fixture 321 and a spinning cylinder 322, which are set on the rotary table 31. The spinning cylinder 322 is set on the side of the second positioning fixture 321 and is used to press down the workpiece located on the second positioning fixture 321, which can ensure the stability of the motor body 101 located on the second positioning fixture 321.

[0041] like Figure 8 As shown, the motor assembly terminal equipment also includes a testing device 40, which is mounted on the frame 11 and located beside the terminal mounting device 30. The testing device 40 includes a third positioning fixture 41, a tester 42, and a fourth lifting drive unit 43. The fourth lifting drive unit 43 can be an electric cylinder, and it and the tester 42 are mounted on a bracket 400. The connection end 421 of the tester 42 is located at the output end of the fourth lifting drive unit 43. After the motor body 101 completes the assembly of the terminal 103 within the terminal mounting device 30, the motor body 101 is manually placed on the third positioning fixture 41. The fourth lifting drive unit 43 drives the connection end 421 to contact the terminal 103 for a continuity test.

[0042] In addition, the cable tray mounting device 20, the terminal mounting device 30 and the testing device 40 are provided with a cover 12 to improve the safety of the equipment.
