As shown in FIG. 12 and FIG. 13, each guide hole 50 includes a first channel 501, a second channel 502, and a third channel 503. The first channel 501 is opened on the first guide die end surface 521 and the first channel. There is a first gap G1 between the wall surface of 501 and the conductive strip 7, the second channel 502 communicates with the first channel 501, a second gap G2 between the wall surface of the second channel 502 and the conductive strip 7, and the third channel 503 communicates with the second The channel 502 is opened at the end surface 522 of the second guide die.

See Figures 18 and 16. FIG. 16 is a schematic image of an end surface of the motor rotor 1 captured by the image measurement module 8 of the present invention. As shown in Figure 18, the assembly method includes the following steps:

Step 100: The rotor fixing module 3 supports and fixes the motor rotor 1.

Step 102: The image measurement module 8 captures images of the plurality of slot holes 10 to obtain a plurality of slot images 11.

Step 104: Measure the size of each of the plurality of slot images 11 according to the plurality of slot images 11.

Step 106: Measure the size of each conductive strip 7.

Step 108: According to the size of the plurality of slot images 11 and the size of each conductive strip 7, a conductive strip 7 corresponding to one of the sizes of the plurality of slot images 11 is selected.

Step 110: The conductive strip 7 corresponding to one of the sizes of the plurality of slot images 11 is inserted into the slot 10 corresponding to one of the sizes of the plurality of slot images 11.

The assembly method for assembling the conductive strip 7 to the motor rotor 1 by using the assembly device 1000 according to the present invention is described in detail below. Please refer to FIG. 18 together. FIG. 18 shows the assembly of the conductive strip 7 to the motor rotor by using the assembly device 1000 according to the present invention. Flow chart of assembling method of slot 10 on 1. First, the rotor fixing module 3 is used to support and fix the motor rotor 1 (step 100), and then the image measurement module 8 is used to capture images of the plurality of slots 10 on the motor rotor 1 to obtain the image shown in FIG. 16 The plurality of slot images 11 (step 102). In this embodiment, the camera module 82 is driven from the closed position as shown in FIG. 1 to the measurement position as shown in FIG. 5 through the lifting cylinder 813, and the camera module 82 When the measurement position shown in FIG. 5 is reached, the camera module 82 can capture images of the plurality of slots 10 on the motor rotor 1.

After the camera module 82 captures the image of the slot image 10, the size of each slot image 11 can be measured according to the plurality of slot images 11 (step 104), so that the slot image 11 can be measured by measuring The size of each slot image 11 is known. Next, the size of each conductive strip 7 is actually measured (step 106). In this way, according to the size of the slot image 11 and the size of each conductive strip 7, the One of the sizes of conductive strips 7 (step 108). That is, in practice, the size of the slot hole 10 of the motor rotor 1 and the size of each conductive strip 7 often differ due to manufacturing tolerances. The abnormal size differences caused by these manufacturing tolerances make it difficult for each conductive strip 7 to be inserted into the slot. The difference between the size of the hole 10 and even the size of the slot 10 and the size of each of the conductive bars 7 makes each of the conductive bars 7 unable to fit into the slot 10. Therefore, the present invention uses image measurement to obtain each slot corresponding to the slot 10 in advance.
