The feeding vibrating bowl 1 is used to screen and arrange the rubber rings in an orderly manner. The conveying track 2 is connected to the feeding vibrating bowl 1 and is used to convey the rubber rings. The material dividing plate 3 is installed at the end of the conveying track 2 and is used to receive the rubber rings. The material pushing mechanism 4 is arranged below the material dividing plate 3. The handling bracket 5 is located on one side of the conveying track 2.

Specifically, the rubber rings are placed into the feeding vibrating bowl 1. The feeding vibrating bowl 1 is a prior art, and its structure will not be described herein again. The rubber rings are screened and arranged in an orderly manner by the feeding vibrating bowl 1, and after being arranged, they are conveyed to the material dividing plate 3 through the conveying track 2. Then, the material pushing mechanism 4 below the material dividing plate 3 pushes the rubber rings into the clamping mold 9. The clamping mold 9 is provided with a material clamping opening that matches the size of the rubber rings, ensuring that the rubber rings are just clamped in the material clamping opening without being deformed. After the rubber rings are clamped, the manipulator driving mechanism 7 drives the handling manipulator 6 to reciprocate to perform the actions of picking and placing materials. Among them, the manipulator driving mechanism 7 uses a motor, and the handling manipulator 6 uses a PPU manipulator (also known as a PPU cam manipulator). Both the PPU manipulator and the manipulator driving mechanism 7 are conventional prior arts, and their structural principles will not be described herein again. The manipulator transfers the rubber rings to the designated assembly station for assembly, completing the automatic feeding process.

Specifically, the rubber rings are continuously conveyed through the conveying track 2, and the rubber rings are fed into the material pushing hole 302 from the feeding port 301. The material pushing hole 302 is a circular through hole that penetrates up and down, facilitating the material pushing mechanism 4 to push the rubber rings upward into the clamping mold 9.

[0025] As a further solution of the present utility model, a detection sensor 303 is arranged on the side of the material pushing hole 302 opposite to the feeding port 301, and the detection sensor 303 is used to detect whether there is a rubber ring in the material pushing hole 302.

[0026] As a further solution of the present utility model, the ejector mechanism 4 includes an ejector bracket 401; a mounting plate 402 mounted on the ejector bracket 401, an upwardly vertical push cylinder 404 is mounted on the mounting plate 402, the output end of the push cylinder 404 is connected with an ejector support plate 405, and an ejector assembly 406 which is inserted and matched with the ejector hole 302 is arranged on the ejector support plate 405. Specifically, during operation, the push cylinder 404 drives the ejector support plate 405 to move upward, thereby driving the ejector assembly 406 to move upward, for pushing the rubber ring upward into the clamping mold 9 for clamping.

[0027] As a further solution of the present utility model, the ejector assembly 406 includes a lower guide rod 4061 inserted through the ejector support plate 405, a first spring 4062 and an ejector sleeve 4064 are sleeved on the lower guide rod 4061, the ejector sleeve 4064 is movably matched with the lower guide rod 4061, and a first snap ring 4065 is mounted on the ejector sleeve 4064, a second snap ring 4066 is mounted at the lower end of the lower guide rod 4061, a first top head 4063 is arranged at the upper end of the lower guide rod 4061, the upper end of the first spring 4062 abuts against the first top head 4063, the lower end of the first spring 4062 abuts against the ejector sleeve 4064, a step is arranged in the inner hole of the ejector sleeve 4064 for abutting against the first spring 4062. When the push cylinder 404 moves upward, it drives the ejector support plate 405 to move upward, drives the lower guide rod 4061 to move upward through the ejector support plate 405, and at the same time jacks up the rubber ring through the upper edge of the ejector sleeve 4064, pushes the rubber ring into the clamping mold 9, and then transports it to the designated station for assembly by the handling manipulator 6.

[0028] As a further solution of the present utility model, a kidney-shaped hole 403 is vertically formed in the mounting plate 402, and a fastening bolt which is threadedly connected with the ejector bracket 401 is arranged in the kidney-shaped hole 403. By providing the kidney-shaped hole 403, it is convenient to adjust the mounting height of the mounting plate 402, so that the ejector assembly 406 reaches the optimal position.

[0029] As a further solution of the present utility model, the clamping die 9 includes an upper guide rod 901 provided on the manipulator jaw 8. A second spring 902 and a material clamping sleeve 903 are sleeved on the upper guide rod 901. The material clamping sleeve 903 is movably matched with the upper guide rod 901, and a material clamping opening adapted to the size of the rubber ring is provided at the lower end of the material clamping sleeve 903. The inner diameter of the material clamping opening of the material clamping sleeve 903 is larger than the outer diameter of the ejector sleeve 4064. A second ejector head 904 is provided at the lower end of the upper guide rod 901, and the second ejector head 904 is aligned with the first ejector head 4063 up and down. When the ejector mechanism 4 moves upward, the second ejector head 904 abuts against the first ejector head 4063. At the same time, the ejector sleeve 4064 pushes the rubber ring upward, and the rubber ring can just be stuck in the material clamping opening without deformation. Compared with the existing material suction or material clamping transfer methods, it has the advantages of no deformation of the rubber ring, accurate positioning, and no material jamming. The second spring 902 is used for the reset of the material clamping sleeve 903. The upper end of the second spring 902 abuts against the manipulator jaw 8, and the lower end of the second spring 902 abuts against the material clamping sleeve 903.

[0030] During specific use, the rubber ring is placed in the feeding vibrating disk 1. The feeding vibrating disk 1 screens and arranges the rubber rings in an orderly manner. After arrangement, they are conveyed to the material dividing plate 3 through the conveying track 2. Then, the ejector mechanism 4 below the material dividing plate 3 pushes the rubber ring into the material clamping opening of the clamping die 9 to ensure that the rubber ring is just stuck in the material clamping opening without deformation. After the rubber ring is clamped, the manipulator driving mechanism 7 drives the handling manipulator 6 to reciprocally perform material taking and placing actions. The manipulator transfers the rubber ring to the designated assembly station for assembly, completing the automated feeding process.
