[0041] The implementation of the present invention will be described in detail below with reference to specific embodiments.

[0042] In this embodiment:

[0043] Refer to Figure 1 As shown, a preferred embodiment of the present invention is provided.

[0044] The stator detection device of the motor production line in this embodiment includes a detection base 4 placed between a feeding device 1 and a discharging device 2. A transfer device 3 is also provided on one side of the detection base 4, the feeding device 1 and the discharging device 2. The transfer device 3 includes two sets of reciprocating mechanical clamping arms 31. The two mechanical clamping arms 31 sequentially send the stator 6 on the feeding device 1 to the detection base 4, and then send it from the detection base 4 to the discharging device 2. A bracket 432 is slidably installed horizontally on the top of the detection base 4. 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. An installation plate 54 is arranged to be lifted and lowered inside the detection box 5. Two sets of guide rails 541 are respectively installed at both ends of the installation plate 54 to horizontally slidably install a withstand voltage detection component 55 and a power connection detection component 56. The withstand voltage detection component 55 and the power connection detection component 56 are respectively used to detect the withstand voltage degree of the 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.

[0045] Refer to the appendix Figure 2 As shown in the figure, a feeding telescopic machine 41 is installed inside the detection base 4. A tray 42 is installed at 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;

[0046] Among them, as shown in the figure Figure 4 As shown in the figure, fixing grooves 421 are opened on both sides of the top of the tray 42. Guide rods 423 are arranged inside the fixing grooves 421. Clamping plates 425 extending to the outside of the top of the tray 42 are sleeved on the outside of the guide rods 423. Electromagnetic parts 422 for adsorbing the clamping plates 425 are also arranged on the inner sides of the ends of the fixing grooves 421. A clamping spring 424 is also sleeved on the outside of the guide rod 423. Both ends of the clamping spring 424 are respectively in contact with the clamping plate 425 and the inner wall of the fixing groove 421 close to the electromagnetic part 422. The two electromagnetic parts 422 adsorb the clamping plates 425 to separate them from each other so as to place the stator 6. The clamping spring 424 will be compressed during the process of adsorbing the clamping plates 425. When the electromagnetic parts 422 are powered off, the clamping spring 424 loses its acting force and is released, pushing the clamping plate 425 to clamp the stator 6 in the middle, which is convenient for positioning and detecting the stator 6.

[0047] Refer to the appendix Figure 3As shown, a positioning motor 43 is installed on one side of the detection base 4. The output shaft of the positioning motor 43 is connected to a lead screw 431. The end of the bracket 432 is slidably connected through the lead screw 431. A direction adjustment motor 52 is installed on one side of the end of the bracket 432. The detection box 5 is connected to the end of the bracket 432 by bearings. The direction adjustment motor 52 is used to drive the detection box 5 to rotate, so as to adjust the relative position between the detection box 5 and the detection base 4 to meet the detection requirements of different positions of stators 6 with different specifications.

[0048] Among them, referring to the attached Figure 6 As shown, a lifting motor 53 is installed on the top of the detection box 5. The top of the detection box 5 is also connected to a transmission ring 533 driven by the lifting motor 53 through bearings. Both sides of the detection box 5 are connected to a first rotating rod 531 through bearings. The two first rotating rods 531 are in gear transmission through the transmission ring 533. The outside of the two first rotating rods 531 is threadedly connected to a connecting block 532. The mounting plate 54 is connected by the two connecting blocks 532. Driven by the lifting motor 53, the transmission ring 533 drives the two first rotating rods 531 to rotate synchronously, and then pushes the connecting blocks 532 threadedly connected to their outsides to perform lifting operations, 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.

[0049] Referring to the attached Figure 5 and the attached Figure 7 As shown, the withstand voltage detection component 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 end of the connecting rod 552 is connected to two pressure application plates 553 through a rotating shaft. A squeezing telescopic machine 554 is also installed on the top of the first guide block 551. The telescopic part of the squeezing telescopic machine 554 penetrates through the connecting rod 552, and a squeezing block 555 is also installed at the telescopic end of the squeezing telescopic machine 554. Referring to the attached Figure 7 As shown, usually, the ends of the two pressure application plates 553 are inclined inwards. Since the squeezing block 555 is placed between the two pressure application plates 553, when the squeezing telescopic machine 554 pushes the squeezing block 555 to move downward, both sides of the squeezing block 555 will push the lower ends of the two pressure application plates 553 to rotate away from each other along the rotating shaft connection part to expand outwards, so as to apply pressure to the groove wall of the winding slot of the stator 6 to detect the withstand voltage strength of the groove wall;

[0050] Referring to the attached Figure 5 、the attached Figure 7 and the attached Figure 8As 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. Two sets of abutting plates 567 are connected to the end of the support plate 563 through a rotating shaft. A high-voltage discharge electrode 58 is further provided at the end of one of the abutting plates 567. The high-voltage discharge electrode 58 is used to apply a voltage to the groove wall of the winding groove of the stator 6. The probe 562 is used to detect the situation where the groove wall is broken down by the high-voltage discharge electrode 58 in real time, so as to judge the insulation of the stator 6.

[0051] Furthermore, a detection motor 564 is installed on the top of the second guide block 561. The output shaft of the detection motor 564 is connected to a second rotating rod 565 extending into the support plate 563. A slider 566 is threadedly connected to the outside of the second rotating rod 565. Diagonal struts 568 are connected between both sides of the slider 566 and one side of the two abutting plates 567 through a rotating shaft. A detection disk 569 is further provided at the end of the support plate 563. The inner sides of the ends of the two abutting plates 567 are respectively in contact with the two side surfaces of the detection disk 569. Touch pieces are evenly distributed on one side surface of the detection disk 569, and the resistance values of the touch pieces increase in sequence. Conductive pieces corresponding to the touch pieces are provided on the inner sides of the ends of the two abutting plates 567. By driving the second rotating rod 565 to rotate through the detection motor 564, the slider 566 threadedly connected to its outside is driven to push the diagonal struts 568, so that the two abutting plates 567 at the end of the support plate 563 are opened and closed, so as to enable the ends of the two abutting plates 567 to abut against the groove wall of the winding groove of the stator 6, so as to detect the width of the winding groove;

[0052] It should be noted that positioning sensors 57 are installed on one side of both the withstand voltage detection component 55 and the power connection detection component 56. Under the action of the positioning sensors 57, the withstand voltage detection component 55 and the power connection detection component 56 can accurately penetrate into each winding groove of the stator 6.

[0053] The present invention provides a stator detection device for a motor production line. During the working process, the mechanical clamping arm 31 of the transfer device 3 sequentially sends the stator 6 on the feeding device 1 to the detection base 4, and then sends it from the detection base 4 to the discharging device 2. On the detection base 4, the feeding telescopic machine 41 sends the stator 6 into the detection box 5. The position of the mounting plate 54 is adjusted through the positioning motor 43, the orientation adjustment motor 52 and the 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 the guide rail 541, and the positioning sensors 57 are used to ensure that the withstand voltage detection component 55 and the power connection detection component 56 accurately penetrate into the winding grooves to respectively detect the withstand voltage degree and the groove wall size of the winding groove wall of the stator 6, and the high-voltage discharge electrode 58 is used to detect the insulation line of the stator 6. Through this device, the automatic detection of the stator 6 on the production line can be realized, the detection efficiency and accuracy are improved, and the error of manual operation is reduced.
