The screws can fall into the fixing frame 28 from the opening 29. Then, after starting the motor 35, the motor 35 can drive the eccentric block 36 to rotate. The eccentric block 36 pushes the fixing frame 28 during the rotation, thereby squeezing the spring 231, so that the screw in the fixing frame 28 shakes and enters the positioning hole 32. Since the positioning hole 32 is provided with a through hole 34, the screw rod of the screw can fall into the through hole 34 in the positive direction. In the process of squeezing the fixing frame 28, the screw machine can push the screw through the elastic sheet 33 to the workpiece, thereby ensuring the stability of the installation and reducing the time for combing the screws.

The moving device includes a plurality of connecting plates 24 and a plurality of connecting rods 25 rotatably connected to the connecting plates 24. The connecting plates 24 are fixedly connected to both sides of the mold 2, one end of the connecting rod 25 is rotatably connected to the top surface of the connecting plate 24, and the end of the connecting rod 25 away from the connecting plate 24 is rotatably connected to the mounting frame 4. The end of the transport channel 6 away from the feed box 7 is fixedly connected to a limiting plate 26, and the limiting plate 26 is arranged below the transport channel 6. The mounting frame 4 is used to install the contact sensor 5. When the workpiece contacts the contact sensor 5, an operation signal can be transmitted to the mounting device, so that the mounting device can be automatically started, thereby realizing automated production. The connecting plates 24 and the limiting plates 26 limit the position of the workpiece to prevent the workpiece from being offset during installation.

[0026] The use process of the present invention is as follows: By starting the clamp 15, one of the workpieces can be grabbed and moved to the mold 2 3, and then the other workpiece that has been injection molded can be stacked in the feed box 7. When in use, the push plate 20 is driven to move by starting the cylinder 19. The push plate 20 moves the bottom workpiece to the side of the transportation channel 6. During the movement, the workpiece can push the baffle 17 to open the bottom of the baffle 17, and the workpiece can slide along the transportation channel 6 into the mold 1 2. In this process, the eccentric block 36 can be driven to rotate by starting the motor 35, so that the screw in the fixed frame 28 shakes and enters the positioning hole 32. Since a through hole 34 is provided in the positioning hole 32, the screw rod of the screw can fall into the through hole 34 in a positive direction. In the process of squeezing the fixed frame 28, the screw machine can push the screw through the elastic sheet 33 to the workpiece to realize the installation combination of the two workpieces.
