[0058] In order to correspondingly transfer the arranged plurality of rivets b to the plurality of mounting holes a1 of the friction plate a. Specifically, in the embodiment, referring to Figure 1 、 Figure 2 and Figure 5 , the taking and placing structure 42 includes a taking and placing frame 421 and a plurality of taking and placing assemblies 422, the taking and placing frame 421 is movably mounted on the movable frame 41 along the up-down direction, the plurality of taking and placing assemblies 422 are connected to the taking and placing frame 421, the plurality of taking and placing assemblies 422 correspond one-to-one to the plurality of positioning holes 211, and each taking and placing assembly 422 is configured to take and place a rivet b. When the taking and placing frame 421 moves downward to approach the positioning piece 21, the plurality of taking and placing assemblies 422 pick up the plurality of rivets b, then move upward, and then the movable frame 41 moves to the assembly area 11, and the plurality of taking and placing assemblies 422 move downward again to approach the friction plate a, and then the plurality of rivets b are placed into the plurality of mounting holes a1.

When each clamping jaw cylinder corresponds to each mounting hole a1, each rivet b is inserted into the corresponding each mounting hole a1, and then the clamping of the rivet b is released, so as to complete the assembly of the rivet b and the friction plate a.

[0060] In the embodiment, referring to Figure 1 、 Figures 5 to 8The taking and placing frame 421 comprises a first connecting plate 4211 and a second connecting plate 4212 which is located at the lower side of the first connecting plate 4211 and oppositely arranged with the first connecting plate 4211 and is provided with a plurality of through holes extending in the up-down direction, the plurality of through holes correspond to the plurality of positioning holes 211 one by one, and the first connecting plate 4211 and the second connecting plate 4212 are both movably connected to the movable frame 41 in the up-down direction; each taking and placing assembly 422 comprises a taking and placing sleeve 4221, a nut 4222, an annular magnet 4223 and a top rod 4224, the taking and placing sleeve 4221 extends in the up-down direction and is fixed in the through hole, the nut 4222 is screwed at the lower end of the taking and placing sleeve 4221, the annular magnet 4223 is arranged in the nut 4222 and located at the lower end of the taking and placing sleeve 4221, and the top rod 4224 extends in the up-down direction, the top rod 4224 is slidably connected in the inner hole of the taking and placing sleeve 4221 and the inner hole of the annular magnet 4223, and the upper end of the top rod 4224 is fixed to the first connecting plate 4211.

[0062] When it is needed to take out a plurality of rivets b from a plurality of positioning holes 211, the movable frame 41 is first driven to move, so that a plurality of nuts 4222 correspond to a plurality of positioning holes 211 one by one, and then the second connecting plate 4212 is driven to move downward, driving a plurality of taking and placing sleeves 4221 to move downward, until the rivet rod b1 of a plurality of rivets b enters a plurality of nuts 4222 one by one, at this time, each rivet rod b1 is arranged in the inner hole of the corresponding annular magnet 4223, so that each annular magnet 4223 can adsorb each corresponding rivet b. Then the second connecting plate 4212 moves upward, driving a plurality of taking and placing sleeves 4221 to move upward, so as to take out a plurality of rivets b from a plurality of positioning holes 211 one by one.

[0066] In the embodiment, the elastic member 4225 is a spring.

[0067] The plurality of mounting holes a1 of the friction plate a to be combined are formed in two circles. Since there is a height difference between the first boss 212 and the second boss 213, in an embodiment, the length of the plurality of taking and placing sleeves 4221 corresponding to the second boss 213 is greater than the length of the plurality of taking and placing sleeves 4221 corresponding to the first boss 212, and the height difference between the plurality of taking and placing sleeves 4221 corresponding to the second boss 213 and the plurality of taking and placing sleeves 4221 corresponding to the first boss 212 is adapted to the height difference between the first boss 212 and the second boss 213, so that the plurality of rivets b in the inner circle and the outer circle can be taken and placed at the same time.

[0068] In the embodiment, referring to Figures 5 to 9 The lengths of the plurality of pick-and-place sleeves 4221 are set to be the same. The appearance is beautiful, and the pick-and-place sleeves are easy to manufacture. The second connecting plate 4212 comprises an inner ring plate 42121 and an outer ring plate 42122.

The plurality of through holes of the outer ring plate 42122 are configured to correspond one-to-one to the plurality of mounting holes a1 of the outer ring of the friction plate a. The friction plate rivet automatic assembly mechanism further comprises a connecting seat 6 and a guide driving member 7. The connecting seat 6 is fixedly connected to the inner ring plate 42121. The guide driving member 7 is installed on the inner ring plate 42121 and is used to drive the outer ring plate 42122 to move up and down.

[0069] Taking the case of taking out a plurality of rivets b from the plurality of positioning holes 211, the inner ring plate 42121 is driven to move downward, driving the outer ring plate 42122 to move downward. When each of the nuts 4222 connected to the inner ring plate 42121 abuts against the upper end surface of the first boss 212, the guide driving member 7 drives the outer ring plate 42122 to move downward, so that each of the nuts 4222 connected to the outer ring plate 42122 abuts against the upper end surface of the second boss 213, thereby enabling the plurality of rivets b corresponding to the inner ring and the outer ring to be taken out at the same time, improving work efficiency. Similarly, when it is necessary to put a plurality of rivets b into the plurality of mounting holes a1 one-to-one, the outer ring plate 42122 is first driven by the guide driving member 7 to move downward until it is flush with the inner ring plate 42121, so as to avoid affecting the disengagement of the subsequent plurality of rivets b.

[0070] In the embodiment, the friction plate rivet automatic assembly mechanism further comprises a sliding mechanism 8.
