[0029] Specifically, the positioning assembly 1 includes a positioning seat 11 and a positioning rod 12. The positioning seat 11 is provided with a positioning hole and a discharge area 112. The discharge area 112 is connected to the positioning hole through the insertion hole 111. The positioning rod 12 is movably located on a side of the positioning hole opposite to the insertion hole 111, that is, the positioning rod 12 is arranged opposite to the insertion hole 111. The first feeding assembly 2 is used to convey the product into the positioning hole, and the second feeding assembly 3 is used to convey the elastic pin into the discharge area 112. When the product is located in the positioning hole, the positioning rod One end of 12 can be extended into the mounting hole of the product to keep the mounting hole of the product connected with the insertion hole 111, that is, to achieve the positioning of the product and prevent it from rotating. After positioning, the insertion component 4 can drive the elastic pin located in the discharge area 112 to be inserted into the mounting hole of the product along the insertion hole 111, and separate the positioning rod 12 from the product. When the elastic pin is inserted into the mounting hole from the other end of the mounting hole, the positioning rod 12 will be gradually squeezed out to complete the entire assembly. It has a high degree of automation, high assembly efficiency, and saves labor costs.

[0030] Specifically, the first feeding assembly 2 includes a first vibration plate 21, a first feeding channel 22, a guide tube 23 and a first pushing rod 24. One end of the guide tube 23 abuts against one side of the positioning seat 11, and a guide hole connected to the positioning hole is provided in the guide tube 23. The first feeding channel 22 is used to connect the first vibration plate 21 and the guide tube 23. The first pushing rod 24 is movably arranged in the guide hole and is used to drive the product located in the guide hole into the positioning hole. When the first vibration plate 21 is working, its vibration transports the product to the first feeding channel 22, and the product is transported to the guide hole of the guide tube 23 through the first feeding, and then the product in the guide hole is driven into the positioning hole by the first pushing rod 24.
