[0020] The implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] In this embodiment: Reference Figure 1 As shown, a preferred embodiment of the present invention is provided.

[0022] The stator detection equipment of the motor production line of this embodiment includes a detection base 4 placed between a loading device 1 and a unloading device 2. A transfer device 3 is also provided on one side of the detection base 4, the loading device 1 and the unloading device 2. The transfer device 3 includes two groups of reciprocating mechanical clamping arms 31. The two mechanical clamping arms 31 sequentially send the stator 6 on the loading device 1 to the detection base 4, and then send it from the detection base 4 to the unloading device 2. A bracket 432 is slidably installed on the top of the detection base 4 in a horizontal direction. A detection box 5 is rotatably installed on the bracket 432. A control device 51 is provided on one side of the detection box 5. A mounting plate 54 is provided inside the detection box 5 for lifting. A withstand voltage detection component 55 and a power connection detection component 56 are horizontally slidably installed at both ends of the mounting plate 54 through two groups of guide rails 541. The withstand voltage detection component 55 and the power connection detection component 56 are respectively used to detect the withstand voltage degree of the winding slot wall of the stator 6 and to detect the size detection and power connection detection operation of the slot wall of the stator 6.

[0023] Refer to the attached Figure 2 As shown, a feeding telescopic machine 41 is installed inside the detection base 4, and a tray 42 is installed on the telescopic part of the feeding telescopic machine 41. The tray 42 is used to carry the stator 6 transferred to the detection base 4, and the feeding telescopic machine 41 is used to send the stator 6 into the detection box 5 for detection operation; Among them, refer to the attached Figure 4 As shown, fixing grooves 421 are provided on both sides of the top of the tray 42, and guide rods 423 are provided inside the fixing grooves 421. The guide rods 423 are externally sleeved with a clamping plate 425 extending to the outside of the top of the tray 42. An electromagnetic component 422 for adsorbing the clamping plate 425 is also provided on the inner side of the end of the fixing groove 421. A clamping spring 424 is also sleeved on the outside of the guide rods 423. The two ends of the clamping spring 424 respectively contact the clamping plate 425 and the inner wall of the fixing groove 421 close to the electromagnetic component 422. The clamping plates 425 are adsorbed by the two electromagnetic components 422 to separate them from each other so as to insert the stator 6. The clamping spring 424 is compressed in the process of adsorbing the clamping plates 425. When the electromagnetic component 422 is powered off, the clamping spring 424 loses its force and is released, pushing the clamping plate 425 to clamp the stator 6 in the center, which is convenient for positioning and detecting the stator 6.

[0024] Refer to the attached Figure 3 As shown, a positioning motor 43 is installed on one side of the detection base 4, and the output shaft of the positioning motor 43 is connected to a screw 431. The end of the bracket 432 is slidably connected through the screw 431. An adjustment motor 52 is installed on one side of the end of the bracket 432. The detection box 5 is connected to the end bearing of the bracket 432. The adjustment motor 52 is used to drive the detection box 5 to rotate, and is used to adjust the relative position of the detection box 5 and the detection base 4 to meet the detection requirements of different positions of stators 6 of different specifications.

[0025] Among them, refer to the attached Figure 6 As shown, a lifting motor 53 is installed on the top of the detection box 5, and a transmission ring 533 driven by the lifting motor 53 is also connected to the top of the detection box 5 through a bearing. Both sides of the detection box 5 are connected with first rotating rods 531 through bearings. The two first rotating rods 531 are gear-driven through the transmission ring 533. The two first rotating rods 531 are externally threadedly connected with connecting blocks 532. The mounting plate 54 is connected through the two connecting blocks 532. Under the drive of the lifting motor 53, the transmission ring 533 drives the two first rotating rods 531 to rotate synchronously, and then pushes the connecting block 532 connected with its external thread to realize the lifting operation, so that the withstand voltage detection component 55, the power connection detection component 56 and the high-voltage discharge electrode 58 can act on the stator 6.

[0026] Refer to the attached Figure 5 and attached Figure 7 As shown, the pressure-resistant detection assembly 55 includes a first guide block 551 sliding on the guide rail 541, the bottom of the first guide block 551 is connected to a connecting rod 552, the ends of the connecting rod 552 are connected to two pressure plates 553 through a rotating shaft, and the top of the first guide block 551 is also equipped with an extrusion telescopic machine 554, the telescopic part of the extrusion telescopic machine 554 passes through the connecting rod 552, and the telescopic end of the extrusion telescopic machine 554 is also equipped with an extrusion block 555, refer to the attached Figure 7 As shown, under normal circumstances, the ends of the two groups of pressure plates 553 are tilted inwardly. Since the extrusion block 555 is placed between the two pressure plates 553, when the extrusion block 555 is pushed downward by the extrusion telescopic machine 554, the two sides of the extrusion block 555 will push the lower ends of the two pressure plates 553 to rotate in opposite directions along the shaft connection part to expand outward, thereby applying pressure to the winding slot wall of the stator 6 to detect the compressive strength of the slot wall. Refer to the attached Figure 5 , Attachment Figure 7 and attached Figure 8 As shown, the power connection detection component 56 includes a second guide block 561 sliding on the guide rail 541, a probe 562 is installed on one side of the second guide block 561, a support plate 563 is connected to the bottom of the second guide block 561, and the end of the support plate 563 is connected to two groups of abutment plates 567 through a rotating shaft, and a high-voltage discharge electrode 58 is also provided at the end of one of the abutment plates 567. The high-voltage discharge electrode 58 is used to apply voltage to the winding slot wall of the stator 6, and the probe 562 is used to detect the breakdown of the slot wall by the high-voltage discharge electrode 58 in real time to determine the insulation of the stator 6.

[0027] Furthermore, a detection motor 564 is installed on the top of the second guide block 561, and the output shaft of the detection motor 564 is connected to a second rotating rod 565 extending to the inside of the support plate 563. The external thread of the second rotating rod 565 is connected to a slider 566. The two sides of the slider 566 and one side of the two abutment plates 567 are connected to an oblique support rod 568 through a rotating shaft. The end of the support plate 563 is also provided with a detection disk 569, and the inner sides of the ends of the two abutment plates 567 are respectively connected to the detection disk 569. 9, one side surface of the detection disk 569 is evenly distributed with contact pieces, and the resistance of the contact pieces increases in sequence. The inner sides of the ends of the two abutment plates 567 are provided with conductive pieces corresponding to the contact pieces. The second rotating rod 565 is driven to rotate by the detection motor 564, and then the slider 566 connected to its external thread is pushed to push the diagonal support rod 568 to open and close the two abutment plates 567 at the ends of the support plate 563, so that the ends of the two abutment plates 567 can abut against the wall of the winding slot of the stator 6 to detect the width of the winding slot; It is worth noting that a positioning sensor 57 is installed on one side of the withstand voltage detection component 55 and the power connection detection component 56. Under the action of the positioning sensor 57, the withstand voltage detection component 55 and the power connection detection component 56 can accurately penetrate into each winding slot of the stator 6.

[0028] The present invention provides a stator detection device for a motor production line. During operation, a mechanical clamping arm 31 of a transfer device 3 sequentially delivers a stator 6 on a loading device 1 to a detection base 4, and then delivers the stator 6 from the detection base 4 to a unloading device 2. On the detection base 4, a feeding telescopic machine 41 delivers the stator 6 into a detection box 5. The position of a mounting plate 54 is adjusted by a positioning motor 43, a direction adjustment motor 52 and a lifting motor 53 to meet the detection requirements of stators 6 of different specifications. The mounting plate 54 in the detection box 5 slides through a guide rail 541, and cooperates with a positioning sensor 57 to ensure that a withstand voltage detection component 55 and a power connection detection component 56 are accurately inserted into a winding groove, so as to respectively detect the withstand voltage degree and the groove wall size of the stator 6 winding groove wall, and utilize a high-voltage discharge electrode 58 to perform insulation wire detection on the stator 6. Through the device, automatic detection of the stator 6 on the production line can be realized, detection efficiency and accuracy are improved, and errors in manual operation are reduced.
