[0020] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0021] like Figures 1 to 6 As shown, the present application discloses a device for automatic assembly and welding of motor coil pins, including a motor platform 1, on which a conveying device 6, a base 2 and a loading device 3 are arranged, the conveying device 6 is arranged between the base 2 and the loading device 3, and is used to transport the coil 100 to be processed to the vicinity of the base 2, and the conveying device 6 can specifically be a conveyor belt; the base 2 is used to place the coil 100 to be processed, so that other structures can process the coil 100 to be processed; the loading device 3 is used to move the coil 100 to be processed to the base 2, and remove the processed coil 100 from the base 2.

[0022] A mounting table 21 is rotatably provided on the base 2, and a sensing device 22 is provided on the mounting table 21. The sensing device 22 is fixed on the base 2 and is used to sense whether the processing point of the coil 100 to be processed is located at a specified position; a stepper motor is provided at the rear of the base 2, and an output shaft is provided at the output end of the stepper motor. The output shaft is fixed to the mounting table 21, and the mounting table 21 can be driven to rotate or move horizontally in a direction away from or close to the base 2 through the output shaft.

[0023] The feeding device 3 includes a base 31 and a pusher rotatably arranged on the base 31. The base 31 is provided with a motor for driving the pusher to rotate and move along its axis. The pusher includes a rotating shaft 321 and a clamping block 322. The diameter of the clamping block 322 is larger than the diameter of the rotating shaft 321. An auxiliary pusher 323 is fixed outside the rotating shaft 321. Specifically, when using the feeding device 3 of the present application to feed materials, the pusher is first driven to rotate to a vertical state. When the conveying device 6 transfers the coil 100 to be processed to the bottom of the pusher, the motor is used to drive the pusher to move downward until the clamping block 322 is inserted into the inner ring of the coil 100 to be processed. By reasonably setting the diameter of the clamping block 322, when the clamping block 322 is inserted into the coil 100 to be processed, there is friction between the clamping block 322 and the coil 100 to drive the coil 100 to be processed to move.

[0024] The motor drives the pusher to rotate until it is in a horizontal state, at which time the clamping block 322 is aligned with the mounting table 21; the mounting table 21 moves toward the direction close to the clamping block 322, and the auxiliary pusher 323 is used to push the coil 100 to be processed, so that the coil 100 to be processed is sleeved on the mounting table 21. After the coil 100 to be processed is sleeved on the mounting table 21, the mounting table 21 is reset, and the pusher rotates to a vertical state, thereby completing the loading of the coil 100 to be processed.

[0025] A plurality of pin installation points are set on the coil 100 to be processed. In the embodiment of the present application, three pin installation points are set. The induction device 22 is used to accurately locate the pin jack on the detection coil 100. When the induction device 22 detects the pin 200 jack, the induction device 22 gives a motor stop signal, and the coil 100 to be processed stops rotating. The positioning is completed, and the assembly and welding of the pin 200 can be performed at this time. After the assembly and welding of the pin 200 is completed, the motor operation signal is transmitted, and the coil 100 continues to rotate until the induction device 22 detects the jack position of the next pin 200, and the above steps are repeated until the three pin installation points of the coil 100 are successfully installed with the pin 200.

[0026] A delivery device 4 and a welding device 5 are arranged around the feeding device 3. The delivery device 4 is used to install the pins 200 to the pin installation points of the coil 100 to be processed, and the welding device 5 is used to weld and fix the pins 200 to the coil 100 to be installed.

[0027] The motor platform 1 is further provided with a driving seat 7 on the side of the feeding device 3. The driving seat 7 includes a fixed seat 71 and a rotating seat 72. The rotating seat 72 is rotatably mounted on the fixed seat 71. The fixed seat 71 is provided with a motor for driving the rotating seat 72 to rotate relative to the fixed seat 71. The delivery device 4 includes a delivery arm 42 and a feeding trough 41. One end of the delivery arm 42 is fixed to the side wall of the fixed seat 71. The feeding trough 41 is fixed to the delivery arm 42 for storing and supplying the pins 200.

[0028] Specifically, the delivery arm 42 includes a base section 421 and a delivery section 422. The base section 421 is fixed on the fixing seat 71. The delivery section 422 is slidably connected to the base section 421. A driving source is provided in the base section 421 for driving the delivery section 422 to move toward the mounting platform 21, so as to realize the delivery and installation of the pin 200 through the delivery section 422. The loading trough 41 is fixed on the delivery section 422, and a slideway 4221 is provided in the delivery section 422. One end of the slideway 4221 passes through the end of the delivery section 422, and the other end is connected to the loading trough 41. When supplying the pins 200, a plurality of pins 200 are stacked and placed in the loading trough 41. The pins 200 fall into the slideway 4221 under the action of gravity. The height of the slideway 4221 is greater than the thickness of one pin 200 and less than the thickness of two pins 200. In addition, a push piece 423 is provided at one end of the slide 4221 close to the loading trough 41. The push piece 423 is used to push the pin 200 to move in the direction of leaving the slide 4221. By reasonably setting the thrust of the push piece 423, each time the push piece 423 pushes the pin 200, a pin 200 can be pushed out of the delivery arm 42, thereby realizing automatic loading and installation of the pin 200.

[0029] It should be noted that the cross-sectional shape of the loading trough 41 matches the shape of the pin 200. When the pin 200 is placed in the loading trough 41, the side walls of the pin 200 are in contact with the inner wall of the loading trough 41, so that multiple pins 200 can be neatly stacked in the loading trough 41, and it is not easy for them to be misaligned and cause the supply of pins 200 to be stuck; at the same time, the width setting of the slide 4221 is limited to the sliding of one pin 200.

[0030] A welding device 5 is also arranged above the delivery device 4. The welding device 5 includes a mounting section 51, a rotation section 52 and a welding section 53 connected in sequence. The end of the mounting section 51 is fixed on the rotating seat 72, so that the welding device 5 can be driven to rotate in a vertical plane as a whole through the rotation of the rotating seat 72; the rotation section 52 is rotatably connected to the end of the mounting section 51, and the rotation section 52 and the mounting section 51 are coaxially arranged, so that when the rotation section 52 rotates around its axis, it can drive the welding section 53 to rotate as a whole; the welding section 53 is hinged to the end of the rotation section 52, so that the welding section 53 can rotate at any angle relative to the rotation section 52. In addition, the rotation section 52 has a length telescopic function. Through the connection of the mounting section 51, the rotation section 52 and the welding section 53, the welding device 5 can be rotated and adjusted in multiple angles and directions, so that the welding of multiple welding points around the pin 200 can be achieved, so as to improve the installation quality of the pin 200 of the coil 100 of the present application, so that the quality of the coil 100 after processing is better.

[0031] After the pins 200 of multiple pin mounting points on a coil 100 are all installed, the loading device 3 can be used again to remove the processed coil 100. Specifically, the pushing member rotates until the pushing member is docked with the mounting table 21. At this time, the mounting table 21 moves in a direction close to the base 2, and the pushing member synchronously follows the mounting table 21 to move toward the base 2, and pushes the coil 100 in a direction away from the mounting table 21 through the surface of the base 2, so that the coil 100 can be sleeved on the pushing member. The pushing member moves in a direction away from the mounting table 21 and then rotates to a vertical state. The coil 100 is then pushed by the auxiliary pushing member 323 so that the coil 100 is separated from the pushing member and falls onto the conveying device 6, and is transported away by the conveying device 6.

[0032] Furthermore, the motor platform 1 is also provided with a first slideway 11 and a second slideway 12, the base 2 is slidably provided on the first slideway 11, and the drive seat 7 is slidably provided on the second slideway 12. The extension direction of the first slideway 11 is perpendicular to the transport direction of the conveyor 6, that is, the base 2 can move along the first slideway 11 toward or away from the welding device 5; the extension direction of the second slideway 12 is parallel to the transport direction of the conveyor 6. By providing the first slideway 11 and the second slideway 12, the horizontal reference positioning of the base 2, the delivery device 4 and the welding device 5 can be completed during the initial setting.

[0033] The present application also provides a method for automatic assembly and welding of motor coil pins, using the above-mentioned device for automatic assembly and welding of motor coil pins, comprising the following steps: S1: The motor coil 100 is transferred to the vicinity of the base 2 by the conveying device 6; S2: driving the pusher to be inserted into the inner ring of the coil 100 to be processed, and the pusher rotates to drive the coil 100 to be processed to move and sleeve outside the mounting platform 21; S3: The sensing device 22 senses that the processing point of the coil 100 to be processed is located at the set position, the delivery arm 42 moves to align with the installation point of the coil 100 to be processed, and pushes the pin 200 into the coil 100 to be processed; S4: After the pin 200 is pushed, the welding device 5 moves to the side of the pin 200, and the side of the pin 200 is welded and fixed by the rotation of the rotation section 52 and the welding section 53; S5: After the coil 100 to be processed is processed, the processed coil 100 is taken down by the loading device 3 and transported away by the conveying device 6 .
