[0019] To make the purpose, technical solution, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0021] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0022] Combination Figure 1-3 As shown, the screw feeding device for assembling plastic parts includes a machine base 1. The machine base 1 is equipped with a linear vibrator 2 and a hopper 3 at the front and rear. The linear vibrator 2 is equipped with several feeding guide rails 4. The bottom plate of the hopper 3 has a notch 5 corresponding to each feeding guide rail 4. The machine base 1 is equipped with a lifting top plate 6 corresponding to each notch 5. The front plate of the hopper 3 is equipped with a vertical plate 7. The back of the vertical plate 7 is rotatably equipped with a combing plate 8 facing each feeding guide rail 4. The front of the vertical plate 7 is equipped with a swing plate 9 for limiting. The vertical plate 7 and the swing plate 8 are respectively equipped with an oval groove 10 and a guide groove 11 corresponding to each combing plate. The top of the combing plate 8 is equipped with a short column 12. The short column 12 passes through the oval groove 10 and is equipped with a guide wheel 13, which is located in the guide groove 11. The bottom of the combing plate 8 is equipped with a sorting brush 14, which is arranged vertically with the feeding guide rail 4. The back of the vertical plate 7 is equipped with a combing assembly, which is used to drive the combing plate to move left and right.

[0023] In the diagram, the bottom plate of the hopper is inclined downwards and forwards. The machine platform is equipped with a linear vibrator and a hopper at the front and back. The linear vibrator is equipped with four feeding guide rails. The bottom plate of the hopper has notches corresponding to the feeding guide rails.

[0024] When using this device, first pour the screws to be fed into the hopper, then start the linear vibrator. The linear vibrator drives the feeding guide rail to vibrate, and the combing assembly drives the combing plate to move left and right. At the same time, the lifting top plate rises and falls synchronously, allowing the screws in the hopper to fall onto the feeding guide rail through the notch. After the screws fall onto the feeding guide rail, the swing plate swings left and right, and the guide groove drives the guide wheel inside to move. The guide wheel drives the combing plate to swing left and right through the short column, combing the screws on the feeding guide rail, correcting and combing their disordered posture. Under the action of the linear vibrator, the screws move along the feeding guide rail towards the assembly station, completing the feeding process. Throughout the process, the oval groove provides guidance and limit for the movement of the short column.

[0025] like Figure 3To ensure the stability of the swing plate, four limiting posts 15 are provided on the front of the upright plate 7. The limiting posts are rectangularly distributed, and limiting grooves 16 are opened at the four corners of the swing plate 8. The limiting posts 15 are located in the limiting grooves 16 at the same positions, and a pair of limiting wheels 17 are provided on the limiting posts 15. The pair of limiting wheels 17 are located on the front and rear sides of the swing plate. The limiting wheels make rolling contact with the swing plate, which not only limits the swing plate but also reduces the friction during the swing, making the swing smoother and more stable.

[0026] As a specific structure, the swing plate 8 has a swing groove 18 at its center, and the back of the upright plate 7 is provided with an eccentric wheel 19. The eccentric wheel 19 is located in the swing groove 18, and the outer periphery of the eccentric wheel 19 slides in contact with the inner wall of the swing groove 18. The combing assembly includes a combing motor 20 installed on the back of the upright plate 7, and the drive shaft of the combing motor 20 is connected to the eccentric position of the eccentric wheel 19.

[0027] During the screw feeding process described above, the combing assembly is used to drive the combing plate to move left and right. That is, the drive shaft of the combing motor drives the eccentric wheel to rotate. When the eccentric wheel rotates, the guide wheel moves in the guide groove, thereby driving the swing plate to swing left and right, so as to realize the combing of the screws on the feeding guide rail by the combing brush.

[0028] To facilitate the smooth entry of screws from the hopper into the feeding guide rails, the front plate of the hopper has slots corresponding to each feeding guide rail, and the tail of the feeding guide rail passes through the slot and is located inside the hopper.

[0029] Furthermore, as a preferred structure, combined with Figure 1-2 The machine base 1 is equipped with a fixed frame 21, and a lifting plate 22 is slidably mounted on the fixed frame 21. A lifting top plate 6 is provided on each notch 5 on the lifting plate 22, and the top surface of the lifting top plate 6 is inclined forward and downward. Furthermore, as... Figure 4 The top surface of the lifting top plate 6 has a downward-facing support groove 23. The machine base 1 is also equipped with a push cylinder 24, and the drive shaft of the push cylinder 24 is connected to the lifting plate 22.

[0030] Because the top surface of the lifting platform is tilted forward and downward, it allows the screws to enter the feeding guide rail more smoothly after the lifting platform lifts them. A certain number of screws are placed in the hopper. Due to the tilted bottom plate of the hopper, the screws concentrate at the notch in the bottom plate under gravity. Next, the push cylinder drives the lifting platform downward, and the four lifting plates on the lifting platform move downward accordingly. The support groove on the top surface of the lifting platform extends into the hopper through the notch, and the screws fall into the support groove, with the screw head engaged and the rod facing downward. Then, the push cylinder drives the lifting platform upward, and the lifting platform carrying the screws exits through the notch and moves to the entrance of the feeding guide rail. The front end of the top of the lifting platform aligns with the tail end of the guide rail, and the screws slide onto the conveying guide rail.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
