[0022] Specifically, in actual applications, it is necessary to connect the feed tray 21 to external feeding equipment, such as vibration tray loading, conveyor belt and other loading facilities; an opening is provided on one side of the placement tray 4 to facilitate the installation of external discharging facilities for discharging parts, thereby achieving the purpose of convenient use.

[0023] like Figure 2 and Figure 3 As shown, the reciprocating mechanism includes a sleeve 7 sleeved on the side wall of the rotating shaft 3, two arc-shaped grooves 8 are provided on the side wall of the sleeve 7, two round rods 9 are fixedly connected to the side wall of the rotating shaft 3, and the round rods 9 extend into the arc-shaped grooves 8. The side wall of the sleeve 7 is fixedly connected to a limit plate 10 near the bottom end, and a spring 11 is sleeved on the side wall of the rotating shaft 3 between the limit plate 10 and the bottom plate 1. The side wall of the sleeve 7 is fixedly connected to a connecting plate 13, and the connecting plate 13 is fixedly connected to the movable plate 15.

[0024] Among them, by setting a reciprocating mechanism, when the rotating shaft 3 rotates, the sleeve 7 can be moved downward by the round rod 9. When the top of the arc groove 8 contacts the round rod 9, the rotating shaft 3 rotates 360°. After that, the motor 2 can be reversed to continue the press-fitting process; in addition, the arc groove 8 can be replaced by a wave groove distributed in a ring shape, and the wave groove can be used to keep the motor 2 rotating in the same direction.

[0025] Two vertical rods 12 are fixedly connected to the bottom surface of the limiting plate 10 , and the bottom ends of the vertical rods 12 pass through the bottom plate 1 and are movably connected thereto.

[0026] like Figure 1 and Figure 4As shown, the pressing mechanism includes a fixed plate 16 fixedly connected to the side wall of the movable plate 15, a screw hole is opened on the top surface of the fixed plate 16, a screw rod 17 is threadedly connected to the screw hole, the top end of the screw rod 17 passes through the support plate 6 and is movably connected to it, and the bottom end of the screw rod 17 is rotatably connected to the pressing plate 18.

[0027] Among them, by setting up a downward pressing component, the downward pressing position of the pressing plate 18 can be adjusted according to parts of different heights. The pressing plate 18 can be driven downward or upward by directly rotating the screw 17, so as to facilitate the press-fitting of parts of different heights. It has a simple structure, high stability in use and high flexibility.

[0028] like Figure 2 As shown, the ejection mechanism includes a barrel 20 fixedly connected to the bottom surface of the placement tray 4, a feed tray 21 fixedly connected to the side wall of the barrel 20, a top plate 22 provided in the inner cavity of the barrel 20, a cylinder 19 fixedly connected to the top surface of the bottom plate 1, and an output end of the cylinder 19 extending into the barrel 20 and fixedly connected to the top plate 22.

In order to prevent the dust cap from getting stuck under the top plate 22 during loading, the top plate 22 can be configured into an L-shape to facilitate shielding the dust cap and achieve the purpose of convenient loading.

[0029] The working principle of this utility model is as follows: first, the feed tray 21 is connected to the external feed device, and the external discharge facility is set on the side of the placement tray 4. When the dust cap enters the barrel 20, the cylinder 19 is started to drive the top plate 22 to move upward to a position lower than the placement tray 4. Then the motor 2 is started, and the output shaft of the motor 2 drives the rotating plate 5 and the round rod 9 to rotate through the rotating shaft 3. The rotating plate 5 rotates and moves the parts to be pressed. The single rotation angle is 90 degrees. The round rod 9 drives the sleeve 7 to move downward through the inclined surface of the arc groove 8. At the same time, the spring 11 is compressed, and the sleeve 7 drives the movable plate 15 to move downward through the connecting plate 13. The movable plate 15 drives the pressure plate 18 to move downward through the fixed plate 16. When the part enters above the dust cap, the pressure plate 18 is just at the top position of the part. At the same time, the cylinder 19 drives the dust cap to rise and press on the part through the top plate 22, and then the cylinder 19 resets, and the next dust cap continues to be pushed onto the top plate 22. When the part is pressed into place, the external discharge facility is used to push the part out to achieve the purpose of pressing.

[0030] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
