Specifically, referring to fig. 12, the lifting assembly includes a top rod 181 movably mounted on the frame 4 and a third eccentric wheel 182 for driving the top rod 181 to lift. In this embodiment, the worktable 41 is provided with a through hole (not shown), and the top end of the top rod 181 penetrates through the through hole and is rotatably connected with the pick-and-place seat 164. The bottom end of the push rod 181 is hinged with a push rod 183 which is used for abutting against the third eccentric wheel 182, and the other end of the push rod 183 is hinged with the frame 4.

Referring to fig. 12, when the rotating shaft 143 drives the third eccentric wheel 182 to rotate from the proximal end abutting against the push rod 183 to the distal end abutting against the push rod 183, the end of the push rod 183 close to the push rod 181 is pushed by the third eccentric wheel 182 to move upwards, thereby pushing the push rod 181 to move upwards, and pushing the pick-and-place holder 164 to move upwards; conversely, when the third eccentric wheel 182 rotates from the far end to the near end against the push rod 183 to abut against the push rod 183, the end of the push rod 183 close to the push rod 181 gradually descends due to the gravity, so that the push rod 181 descends along with the end of the push rod 183, and the pick-and-place seat 164 is driven to descend, thereby completing the ascending and descending of the pick-and-place seat 164.

The application has the implementation principle that: when the chip 3 is clamped at the clamping end 2 of the pin 1, the pin 1 is conveyed to a position opposite to the feeding table 10 through the conveying table 6, so that the material guiding groove on the feeding table 10 is aligned with the clamping end 2 of the pin 1, then the cam 145 is driven to rotate through the driving motor 144, and the feeding table 10 moves towards the conveying table 6, and the feeding table 10 is further gradually close to the clamping end 2 of the pin 1 until one side of the clamping end 2 of the pin 1, which faces the conveying table 6, of the feeding table 10 is slightly contacted with the clamping end 2 of the pin 1, or the clamping end 2 of the pin 1 and the feeding table 10 have a small gap. Then, the two lifting rods 115 are driven to lift asynchronously by the first eccentric wheel 116, so that the upper separation plate 111 and the lower separation plate 112 move towards each other until the upper separation teeth 113 and the lower separation teeth 114 respectively abut against the two pin 1 lines of the clamping terminal 2, thereby spreading the clamping terminal 2 of the pin 1 to facilitate placing the chip 3 into the clamping terminal 2. In the process of separating the clamping ends 2 of the pins 1 by the pin separating device, the chip pick-and-place device sucks the chip 3 in the pick-and-place groove 1522 of the material arranging table 152, places the chip 3 on the guide groove 102 of the material loading table 10, and then the material pushing plate 13 on the material pushing frame 12 pushes the chip 3 to approach the clamping ends 2 of the pins 1 until the chip 3 is pushed to the clamping ends 2 of the pins 1. After the chip 3 is pushed to the holding end 2 of the pin 1, the upper separation plate 111 and the lower separation plate 112 move in the direction away from each other, and the holding end 2 of the pin 1 resets under the action of its own elastic force, so that the chip 3 is clamped, thereby completing the step of holding the chip 3 by the pin 1.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
