[0017] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0018] Figure 1 It is a structural schematic diagram of the utility model; Figure 2 It is a schematic diagram of the internal structure of the cylinder of the utility model.

[0019] Combined with Figure 1 and attached Figure 2As shown, a nut embedding assembly device includes a base plate 1, a nut pushing mechanism 2, a connecting plate 3, a positioning pin 4, a product grabbing mechanism 5, a cylinder 6, a spring 7, a ball 8, a nut placement channel 9, and a ball placement channel 10. The nut pushing mechanism 2, the connecting plate 3, and the product grabbing mechanism 5 are fixed on the base plate 1. The connecting plate 3 is provided with a positioning pin 4 and a cylinder 6. A nut placement channel 9 and several ball placement channels 10 are provided in the cylinder 6. Several ball placement channels 10 are distributed around the nut placement channel 9. The ball placement channel 10 is connected to the nut placement channel 9. The spring 7 is placed in the ball placement channel 10, and the spring 7 is connected to the ball 8.

[0020] The opening diameter of the ball placement channel 10 is smaller than the diameter of the ball 8 , so that a small part of the ball 8 passes through the opening of the ball placement channel 10 and is located in the nut placement channel 9 .

[0021] The nut pushing mechanism 2 is composed of a push rod 21 and a push rod driving cylinder 22. The push rod 21 is fixed on the piston rod of the push rod driving cylinder 22. The cylinder body of the push rod driving cylinder 22 is fixed on the base plate 1. The end of the push rod 21 is placed in the nut placement channel 9 of the cylinder body 6.

[0022] The product grabbing mechanism 5 is composed of a clamping jaw 51 and a clamping jaw driving cylinder 52 . The clamping jaw 51 is fixedly connected to the piston rod of the clamping jaw driving cylinder 52 , and the cylinder body of the clamping jaw driving cylinder 52 is fixed on the base plate 1 .

[0023] The clamping jaw 51 is fixed to the piston rod end of the clamping jaw driving cylinder 52 through a connecting block 53 . A guide rod 54 is fixed to the connecting block 53 . The guide rod 54 passes through a guide hole on the base plate 1 .

[0024] A threaded hole is provided on the connecting plate 3 , and a threaded tube 11 is provided at the rear end of the cylinder 6 . The threaded tube 11 is threadedly connected in the threaded hole of the connecting plate 3 .

[0025] A support rod 12 is fixed between the connecting plate 3 and the base plate 1 .

[0026] The working method of the present application is that the substrate 1 is fixed on the multi-axis robot, and the multi-axis robot drives the device to move. First, insert the nut into the nut placement channel 9. When the nut partially enters the nut placement channel 9, it will squeeze back the parts of the balls 8 that have passed through. At this time, the spring 7 is in a compressed state. After the nut continues to move forward and completely enters the nut placement channel 9, the annular groove on the nut will align with the opening of the ball placement channel 10, so that the rebound of the spring 7 will drive the balls 8 to move in the opposite direction until a small part of the balls 8 is inserted into the annular groove of the nut, so that the balls 8 will clamp the nut in the cylinder 1.

[0027] After the nut is positioned in the cylinder 1, the cylinder 1 is moved to the injection molding machine. After the positioning pin 4 is inserted into the positioning hole of the injection molding machine, the cylinder 1 is accurately placed in the injection molding groove of the injection molding machine. Then the push rod driving cylinder 22 drives the push rod 21 to move in a straight line along the nut placement channel 9 until the nut is pushed out of the cylinder 1 and enters the injection molding machine. Finally, after the device is moved away from the injection molding machine, the injection molding machine starts to work. After the product is injection molded, the device is moved to the injection molding machine again, and the piston rod of the clamp driving cylinder 52 drives the clamp 51 to move into the injection molding groove to take the product with the embedded nut out of the injection molding machine.

The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
