[0038] In combination Figure 12As shown, in the present application, the magnet assembly 100 is formed by mutual bonding of three magnets (the first magnet 101, the second magnet 102 and the third magnet 103), that is, the first magnet 101, the second magnet 102 and the third magnet 103 are placed on the bearing plate 20 with a spacing therebetween, the bearing plate 20 is preferably of a magnetic material, and the three magnets can be positioned on the bearing plate 20 to remain in position. Specifically, the second magnet 102 is placed at the middle position on the bearing table 21, one end of which abuts against the stopper 22, and the other end of which protrudes from the bearing table 21 and is located above the second slot 202. The first magnet 101 and the third magnet 103 are placed on the bearing table 21, one end of each of which also abuts against the stopper 22, and each of which is located above the first slot 201. A plurality of the first magnet 101, the second magnet 102 and the third magnet 103 can be positioned in a plurality of positioning areas 2A on the bearing plate 21.

Specifically, the pressing mechanism 30 is placed on the bearing plate 20, at least part of the lower end surface of which abuts against the upper end surfaces of the three magnets, so as to ensure that the magnets do not deviate in the vertical direction during movement. The side pushing mechanism 40 is actuated, the clamping jaw cylinder 41 drives the connecting plate 42 to move the side pushing assembly 43, so that the end of the side pushing assembly 43 protrudes into the first slot 201 to horizontally push the magnet. Specifically, the first magnet 101 and the third magnet 103 are pushed from opposite sides of the bearing plate 20 to abut against and bond to the second magnet 102. The pushing mechanism 50 is actuated, the connecting shaft 52 is provided with a plurality of pushing plates 53, in an embodiment, each pushing plate 53 is fixed to the connecting shaft 52, and the upper end is embedded in each second slot 202. The translation cylinder 51 drives the connecting shaft 52 to move the pushing plate 53, so that the pushing plate 53 abuts against one end of the bonded three magnets away from the stopper 22. Through the joint action of the pushing plate 53 and the stopper 22, the two end surfaces of the first magnet 101, the second magnet 102 and the third magnet 103 are flush, and the assembly of the three magnets is completed to form the magnet assembly 100.

[0039] The present application positions a plurality of magnet assemblies before assembly on the bearing plate 20, ensures the stability in the vertical direction during assembly by the pressing mechanism 30, and realizes the abutment between the magnets and the accurate position of the magnets after abutment by the side pushing mechanism 40 and the pushing mechanism 50, so as to improve the assembly efficiency and accuracy of the magnet assembly 100.

[0041] Further, the side pushing plate 431 comprises a main plate 4311 and at least one abutting plate 4312 arranged on the main plate 4311, the main plate 4311 is arranged on the first guide rail pair 433, and the abutting plate 4312 is arranged at the end of the main plate 4311 for extending into the first slot 201 to abut against the first magnet 101 or the third magnet 103; preferably, two abutting plates 4312 are arranged on one main plate 4311, two first slots 201 are arranged on one side of one bearing area 2A for corresponding to the two abutting plates 4312, which can realize the balance when the first magnet 101 or the third magnet 103 is pushed sideways, and a supporting plate 4313 is arranged between the pair of abutting plates 4312, and the bottom groove 203 is communicated between the pair of first slots 201, when the abutting plate 4312 extends into the first slot 201, the supporting plate 4313 extends into the bottom groove 203, because the bearing plate 21 has a certain length, and the pressing mechanism 30 is arranged at the upper end of the bearing plate 21 for pressing the magnets in each positioning area 2A, therefore, in order to avoid the deformation of the bearing plate 21 after being pressed, especially the downward bending of the middle part due to the lack of support, the supporting plate 4313 extends into the bottom groove 203 when the side pushing mechanism 40 pushes the magnets, which can effectively avoid the downward bending and other deformations of the bearing plate 20, and further make the pressing mechanism 30 and the bearing plate 20 in a horizontal state jointly act on the upper and lower ends of the magnets.

[0042] Because the pushing plate 53 is fixed on the connecting shaft 52 without buffering, it is easier to cause damage to the thin magnets when abutting against the end of the three magnets away from the stop block 22, for example, Figures 7 to 9As shown, preferably in another embodiment of the present application, the pushing mechanism 50 further comprises a plurality of clamping rings 541 and a third spring 542, the clamping rings 541 are fixed on the connecting shaft 52, the clamping rings 541 are formed by embedding the clamping springs on the circumferential sidewall of the connecting shaft 52, the pushing plate 53 is non-fixed, the pushing plate 53 is slidably arranged on the machine table 10 through the second guide rail pair 533, the lower part of the pushing plate 53 is sleeved on the connecting shaft 52 and located between a pair of clamping rings 541, the upper part of the pushing plate 53 extends into the second insertion slot 202, the third spring 542 is sleeved on the connecting shaft 52, and the two ends thereof abut against the clamping rings 541 and the pushing plate 53 respectively, that is, the pushing plate 53 is slidably arranged on the connecting shaft 52, and one end thereof abuts against one clamping ring 541 and the other end thereof abuts against the other clamping ring 541 through the third spring 542, when the pushing plate 53 abuts against the end of the magnet away from the stop block 22, it can compress the third spring 542 to move relative to the connecting shaft 52, has a buffering effect, can avoid rigid extrusion of the magnet to avoid damage of the magnet, when the connecting shaft 52 is driven to reset by the translation cylinder 51, the pushing plate 53 is reset after abutting against the clamping ring 541 based on the recovery of the third spring 542.

[0043] Further, the pushing plate 53 comprises a horizontal plate 531 and a vertical plate 532, the horizontal plate 531 is connected with the second guide rail pair 533, the horizontal plate 531 is provided with a side hole 530, one side of the third spring 542 is embedded in the side hole 530, the side hole 530 can provide a larger movement space for the pushing plate 53, and also can limit the third spring 542 to avoid being extruded and arched, the vertical plate 532 is arranged on the horizontal plate 531 and the upper part thereof extends into the second insertion slot 202.

[0044] As shown in Figure 2 , Figure 10 and Figure 11 , preferably, the material pressing mechanism 30 comprises a positioning member 31 and a pressing part 32, the pressing part 32 abuts against the bearing plate 10, the positioning member 31 can select a pair of quick clamps, which are arranged on the opposite sides of the machine table 10, and abut against and press the pressing part 32 to ensure the stability of the pressing part.

[0045] Further, the pressing part 32 comprises a bottom plate 321, an inverted U-shaped plate 322, pressing plates 323 and a first spring 324. The bottom plate 321 is used to abut against the bearing plate 20 after being pressed by the positioning member 31, and is provided with a plurality of through holes 3210. The inverted U-shaped plate 322 is arranged on the bottom plate 321. The plurality of pressing plates 323 are arranged in the through holes 3210 and can move up and down. The upper and lower ends of the first spring 324 abut against the inverted U-shaped plate 322 and the pressing plate 323 respectively. The pressing plate 323 is driven by the first spring 324 to move downward and abut against the magnets on the bearing table 21. The specific working process of the pressing part 32 is as follows: the bottom plate 321 is abutted against the bearing plate 20, and the bottom plate 321 is fixed by the positioning member 31 (such as a quick clamp). Since the upper end position of the first spring 324 is limited, when the pressing plate 323 abuts against the magnets in the positioning area 2A and makes the pressing plate 323 have a tendency to move upward, the first spring 324 is compressed to exert a counterforce on the pressing plate 323, so that the pressing plate 323 exerts a downward pressing action on the upper ends of the three magnets to avoid the deviation of the magnets in the vertical direction, and also avoids the rigid downward pressing on the magnets to avoid the damage of the magnets by the elastic extrusion on the magnets. In order to ensure the accurate positioning of the pressing plate 323 and the positioning area 2A, a pair of first positioning holes 200 and a pair of second positioning holes 320 are respectively arranged on the bearing plate 20 and the bottom plate 321, and a pair of positioning columns 11 are arranged on the two sides of the machine table 10.

The lower end surface of the pressing head 3232 is respectively provided with a first recess 3201 and a second recess 3202 matched with the first slot 201 and the second slot 202. When the pressing head 3232 abuts against the magnets on the bearing table 21, the first recess 3201 and the second recess 3202 can respectively provide a space for the side pushing assembly 43 (i.e. the abutting plate 4312) and the top pushing plate 53 (i.e. the vertical plate 532).
