DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0026] Reference Figures 1-8The cam 6 is provided with a plurality of support plates 22, and the support plates 23 are provided with a plurality of support plates 24. The support plates 23 are provided with a plurality of support plates 26. The support plates 23 are provided with a plurality of support plates 27.

[0027] A rectangular opening is symmetrically provided on the upper surface of the base 1. A vertical plate 9 is fixedly sleeved on the first spring rod 7. The tops of the two vertical plates 9 pass through the two rectangular openings respectively and are fixedly installed with an inclined plate 10. The driving shaft of the telescopic cylinder 11 is fixedly installed with a connecting plate 13 through a connecting rod. A push rod 14 is symmetrically fixedly installed on the surface of the connecting plate 13. A through hole 15 for the push rod 14 to pass through is provided on the surface of the inclined plate 10. A rotating shaft 16 is installed in the through hole 15 for horizontal rotation. The rotating shaft 16 is connected to the inclined plate 10 through an elastic component. The elastic component includes Including a torsion spring 19, one end of the rotating shaft 16 passes through the inclined plate 10 and is fixedly installed with a mounting block. The torsion spring 19 is sleeved on the rotating shaft 16, and both ends are fixedly connected to the mounting block and the inclined plate 10 respectively. A force plate 17 is fixedly sleeved on the rotating shaft 16, and the force plate 17 is restricted from rotating upward by a limiting component. The limiting component includes a limiting port 18 opened on the surface of the inclined plate 10 and connected to the through port 15. The upper surface of the force plate 17 is against the wall of the limiting port 18, and the two supporting rods 14 correspond to the positions of the two through ports 15 respectively.

[0028] In the initial state, that is, when the pressure plate 12 is at the highest point, the two supporting plates 8 will abut against each other and close the bottom opening of the placement space. Then, the retaining frame to be assembled is placed in the placement space. After the ball bearings are placed on the assembly groove of the retaining frame, the telescopic cylinder 11 is started to control the pressure plate 12 to move downward. In the process of downward movement, the two push rods 14 will move downward together. The two push rods 14 will pass through the two through ports 15 respectively and abut against the upper surfaces of the two force plates 17 respectively. The force plates 17 will rotate downward under the pressure of the push rods 14. After the pressure plate 12 presses multiple balls into the assembly groove of the retaining frame, the push rods 14 will no longer contact the force plate 17. The force plate 17 will quickly rotate and reset under the elastic potential energy of the torsion spring 19.

[0029] When the push rod 14 moves up and contacts the lower surface of the force-bearing plate 17, the force-bearing plate 17 cannot rotate upward. At this time, the push rod 14 will slide along the inclined surface of the inclined plate 10. Under the action of the inclined surface, the first spring rod 7 will contract, and the two supporting plates 8 will move away from each other until the two supporting plates 8 move to the point where they no longer close the bottom of the placement space. The assembled retainer in the placement space will fall from the bottom opening of the placement space into the installation groove 3, thereby completing the automatic unloading of the retainer without manual unloading, thereby improving the assembly work efficiency. As the pressure plate 12 and the push rod 14 move up, when the push rod 14 moves to the point where it no longer contacts the inclined plate 10, the supporting plate 8 will quickly move back to its original position under the elastic potential energy of the first spring rod 7, and the two supporting plates 8 will contact each other again and block the bottom opening of the placement space.

[0030] The locking assembly includes two second spring rods 20. The lower surface of the base 1 is symmetrically fixed with mounting plates. The two second spring rods 20 are respectively fixed on the surfaces of the two mounting plates. A locking opening 21 for inserting the ends of the two second spring rods 20 is opened horizontally on the surface of the bottom of the cylinder 5.

[0031] The assembled retainer dropped from the placement space will be sleeved on the cylinder 5. As the number of retainers cut increases, when the retainer needs to be taken out from the mounting groove 3, it is necessary to control the two second spring rods 20 to retract so that the ends of the second spring rods 20 are moved out of the locking openings 21 to release the lock on the cylinder 5. Then, after controlling the cylinder 5 to move out of the mounting groove 3, multiple retainers can be taken out of the mounting groove 3, which is convenient and quick.

[0032] A buffer layer is bonded to the upper surface of the supporting plate 8. The buffer layer is made of rubber. The rubber buffer layer has good elasticity and viscosity, thereby reducing the force between the retaining frame and the supporting plate 8 when the pressure plate 12 moves downward rapidly and presses multiple balls into the retaining frame.

[0033] In the present invention, in the initial state, that is, when the pressure plate 12 is at the highest point, the two supporting plates 8 will abut against each other and close the bottom opening of the placement space, and then the retaining frame to be assembled will be placed in the placement space, and then after the ball bearings are placed on the assembly groove of the retaining frame, the telescopic cylinder 11 will be started to control the pressure plate 12 to move downward. In the process of downward movement, the two push rods 14 will move downward together, and the two push rods 14 will pass through the two through holes 15 respectively, and abut against the upper surfaces of the two force plates 17 respectively. The force plates 17 will rotate downward due to the pressure of the push rods 14. After the pressure plate 12 presses multiple balls into the assembly groove of the retaining frame, the push rods 14 will no longer contact the force plates 17, and the force plates 17 will quickly rotate and reset under the elastic potential energy of the elastic component. At this time, the telescopic cylinder 11 moves the pressure plate 12 upward. When the push rod 14 moves to the point where it no longer contacts the inclined plate 10, the supporting plate 8 will quickly move back to its original position under the elastic potential energy of the first spring rod 7, and the two supporting plates 8 will contact each other again and block the bottom opening of the placement space.

[0034] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
