[0001] This utility model relates to the field of pin assembly technology, and specifically to an automatic pin assembly device. Background Technology

[0002] Pins are a widely used component in automotive parts, serving to fix or limit movement. In current automotive parts assembly processes, pins are generally assembled manually using tools. Due to the small size, smooth surface, and tight assembly gaps of pins, manual assembly is extremely inconvenient, slow, inefficient, and lacks guaranteed accuracy. Utility Model Content

The receiving component receives pins falling from a vibrating plate. The pushing mechanism pushes the pins in the receiving component from the receiving position to the pressing position. The pressing component presses the pins in the pressing position into the automotive parts.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and preferred embodiments.

[0019] See Figures 1-4An automatic pin assembly device includes a column 1 and a lifting mechanism, a pressing mechanism and a pushing mechanism installed on the column 1.

[0020] The column 1 is rectangular in shape, with a base at its lower end. The base has mounting holes, through which the column can be installed on the automatic production line for pin assembly.

[0021] A lifting mechanism is connected to the upper end of the column. The lifting mechanism mainly consists of a lifting cylinder 2, a first guide rail slider 3, a lifting plate 4, limit screws 18, and lifting buffers 19. There are two sets of first guide rail sliders 3, symmetrically and vertically installed on the upper side of the column. Two limit screws 18 are installed above and below one set of guide rail sliders, and two lifting buffers 19 are installed above and below the other set of guide rail sliders. The lifting plate 4 is slidably connected to the two guide rails via four sliders. The lifting cylinder 2 is fixedly installed at the upper end of the column, with its piston rod extending vertically downwards to connect to the lifting plate, driving the lifting plate 4 to move stably up and down. The lifting plate 4 is a vertically arranged flat plate.

[0022] The pressing mechanism mainly consists of a fixed plate 5, a first guide block 10, a blown nail pipe 11, a pressing cylinder 12, a second guide block 13, a second guide rail slider 14, a pipe joint 15, and a pressing rod 16. The fixed plate 5 is vertically fixed on the lifting plate 4, with its front side serving as the mounting surface and its back side having reinforcing ribs 51 to improve the stability of the device. The second guide rail slider 14 is vertically fixed to the outside of the mounting surface of the fixed plate. The first guide block 10 is fixed below the second guide rail slider 14. The pressing cylinder 12 is fixedly mounted above the second guide rail slider 14 via a cylinder fixing plate. The second guide block 13 is connected to the guide rail via a slider, and the piston rod of the pressing cylinder 12 extends vertically downwards and connects to the second guide block 13. The upper end of the pressing rod 16 is embedded in the second guide block 13, and the lower end extends vertically downwards into the first guide block 10.

[0023] Two through holes are vertically spaced along the length of the first guide block 10. One serves as the first pin channel, and the other as the pressure rod channel. A pipe connector 15 is installed at the inlet end of the first pin channel. The lower end of the blow-nail tube 11 is fixedly connected to the pipe connector 15, and the upper end extends vertically upward and can slide through the cylinder fixing plate. The inner diameter of the first pin channel is equal to the inner diameter of the blow-nail tube, and the inner diameter of the blow-nail tube is adapted to the pin diameter. The inner diameter of the pressure rod channel is adapted to the pressure rod diameter and is slightly smaller than the inner diameter of the first pin channel. The lower end of the pressure rod 16 extends into the first guide block 10 and is slidably connected to the pressure rod channel.

[0024] The pushing mechanism mainly consists of a pushing cylinder 6, a slide plate 7, a pushing buffer 8, a pushing block 9, a guide pin 17, and an alignment pipe 20. The pushing cylinder 6 and the slide plate 7 are fixedly installed on the lower side of the mounting surface of the fixed plate. The slide plate 7 is located directly below the first guide block 10, and a slide rail is provided on its upper side, parallel to the length direction of the first guide block. The pushing block 9 is slidably disposed in the slide plate 7, and the top of the pushing block 9 is fixedly connected to the guide pin 17. The bottom surface of the first guide block 10 is provided with a guide groove 101 parallel to the slide rail of the slide plate, and the guide pin 17 is slidably engaged with the guide groove 101. The pushing cylinder 6 is installed on the side near the column, and its piston rod extends horizontally outward and is fixedly connected to the pushing block 9 through a joint. The pusher block 9 has a vertically formed through hole, which serves as a second pin channel. The inner diameter of the second pin channel is equal to that of the first pin channel, and its height is slightly greater than the height of a single pin, allowing it to accommodate only one pin and carry it from the receiving position to the pressing position. The slide plate 7 has a vertically formed through hole at the bottom of its slide, which serves as a third pin channel. The inner diameter of the third pin channel is equal to that of the second pin channel, and its height is approximately one-third that of the second pin channel, reducing the stroke of the pressing cylinder 12 and improving pin assembly accuracy. The lower end of the second pin channel is axially connected to the alignment tube 20. In this embodiment, the alignment tube prevents the pin from being suspended during pressing, facilitating pin positioning and guidance.

[0025] A pusher buffer 8 is provided on the outside of the pusher block 9. When the piston rod of the pusher cylinder 6 retracts to the limit position, the second pin channel in the pusher block 9 is aligned and connected with the first pin channel of the first guide block 10. This position is the pin receiving position. When the piston rod of the pusher cylinder 6 extends to the limit position, the second pin channel in the pusher block 9 is aligned and connected with the pin pressing rod channel of the first guide block 10. This position is the pin pressing position.

[0026] When the pin is in the receiving position, the pin passes through the blown pin tube 11 and the first pin channel in the first guide block 10 in sequence, and falls into the second pin channel in the pusher block 9; when the pin is in the pressing position, the pressing rod 16 presses the pin in the pusher block 9 through the third pin channel and the alignment tube 20 into the automotive parts.

[0027] The working principle of this utility model is as follows: The pusher block 9 is in the pin receiving position, and the alignment tube 20 is directly above the product hole. The pin is blown from the vibrating plate into the pusher block 9 through the blow pipe 11. The lifting cylinder 2 extends the cylinder rod, and the lifting plate 4 descends. At this time, the distance between the alignment tube 20 and the product is adjusted to 0.5mm. Under the action of the pusher cylinder 6, the pusher block 9 moves from the pin receiving position to the pin pressing position. The pressing cylinder 12 extends the cylinder rod, and the guide block 13 drives the pressing rod 16 to press down, pressing the pin into the product through the alignment tube 20.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications are also within the protection scope of the present utility model.
