[0032] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0033] To fully understand this utility model, detailed steps and structures will be presented in the following description to illustrate the technical solution of this utility model. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0034] Reference Figure 1-2As shown, this utility model provides a single-station automatic pin pressing mechanism, which is used to press pins onto tooling 1. It includes a turntable assembly 100, a feeding assembly 200, a pressing assembly 300, and a support assembly 400.

[0035] Turntable assembly 100

[0036] like Figure 3 As shown, the turntable assembly 100 includes a motor 101, a turntable 102, and a photoelectric sensor 103. The output shaft of the motor 101 is connected to the turntable 102. The turntable 102 has multiple stations along its circumference for installing tooling. The tooling is detachably connected to the turntable 102 via locating pins and bolts. One of the fixed stations is a pressing station. The photoelectric sensor 103 is installed beside the turntable 102 to detect whether there is a product at the pressing station.

[0037] Support component 400

[0038] like Figure 7-9 As shown, the support assembly 400 is located directly below the press-fitting station and includes a first horizontal cylinder 401, a ramp slide plate 402, a support column 403, a linear bearing 404, and a linear bearing fixing plate 405. The piston rod of the first horizontal cylinder 401 is connected to the ramp slide plate 402. The linear bearing 404 is fixed on the linear bearing fixing plate 405. The support column 403 passes through the linear bearing 404, and the lower end of the support column 403 contacts the inclined surface of the ramp slide plate 402. The first horizontal cylinder 401 drives the ramp slide plate 402 to slide, causing the support column 403 to move upward and press against the lower surface of the tooling 1.

[0039] like Figure 7 As shown, the support assembly 400 also includes a sliding groove plate 406, which is fixed on the linear bearing fixing plate 405. The sliding groove plate 406 has a groove adapted to the ramp slide plate 402, and the ramp slide plate 402 is slidably disposed in the groove.

[0040] like Figure 8-9 As shown, both side walls of the support column 403 are provided with guide grooves 4031; the ramp slide plate 402 is a U-shaped plate, with its two parallel edges slidingly engaging with the guide grooves 4031, and the upper surfaces of the two parallel edges being inclined surfaces 4021. When the ramp slide plate 402 slides forward, the inclined surfaces 4021 engage with the guide grooves 4031 in a wedge shape, thereby driving the support column 403 to move upward. After the ramp slide plate 402 retracts, the support column 403 automatically falls and returns to its original position under the action of gravity and the wedge engagement.

[0041] Optionally, the upper end of the support column 403 is provided with a buffer pad, which is made of elastic material.

[0042] Press-fit assembly 300

[0043] like Figure 6 As shown, the press assembly 300 is located directly above the press station and includes a press 301 and a press head 303. The press 301 drives the press head 303 to move up and down, and the press head 303 has a vacuum channel inside for adsorbing the pin. The press head 303 uses vacuum to adsorb the pin and then presses it down to install the pin onto the tooling.

[0044] Feeding assembly 200

[0045] like Figure 4-5 As shown, the feeding assembly 200 includes a vibratory feeder 201, a feeding pipe 202, a second horizontal cylinder 203, a sliding plate 204, and a sliding receiving plate 205. The inlet of the feeding pipe 202 is connected to the vibratory feeder 201, and the outlet of the feeding pipe 202 is connected to a transfer pipe 2021. The vibratory feeder 201 conveys pins to the feeding pipe 202 and outputs them from the transfer pipe 2021.

[0046] The piston rod of the second horizontal cylinder 203 is connected to the sliding plate 204. The sliding receiving plate 205 is installed on the sliding plate 204. The top of the sliding receiving plate 205 is provided with a receiving port. The second horizontal cylinder 203 drives the receiving port of the sliding receiving plate 205 to reciprocate horizontally between the outlet of the feeding pipe 202 and the bottom of the pressure head 303. On the one hand, it receives the pins conveyed by the feeding pipe 202, and on the other hand, it transfers the pins to the bottom of the pressure head 303 so that the pressure head 303 can absorb them.

[0047] Optionally, the feeding assembly 200 further includes a first horizontal slide rail 206, a pin receiving seat 207, and a fiber optic sensor 209. A sliding plate 204 is slidably mounted on the first horizontal slide rail 206 and slides horizontally along the length of the first horizontal slide rail 206. A pin receiving seat 207 is fixedly mounted on the sliding plate 204. A sliding receiving plate 205 is slidably mounted on top of the pin receiving seat 207. A spring 208 is provided between the sliding receiving plate 205 and the pin receiving seat 207.

[0048] Optionally, the fiber optic sensor 209 is disposed beside the sliding receiving plate 205 to detect whether there is a pin inside the receiving port.

[0049] The working process of this utility model is briefly described as follows:

[0050] During operation, the vibratory feeder 201 blows the pins into the sliding receiving plate 205 through the feeding pipe 202 and the transfer pipe 2021, and the fiber optic sensor 209 detects the signal. The second horizontal cylinder 203 extends and moves the sliding receiving plate 205 on the sliding plate 204 out, so that the sliding receiving plate 205 carrying the pins leaves the bottom of the transfer pipe 2021 and then moves to the bottom of the pressure head 303, so that the pins in the sliding receiving plate 205 are located directly below the pressure head 303.

[0051] As the press 301 moves downward, the press head 303 descends to the pin inside the sliding receiving plate 205. As the press 301 continues to press down, the sliding receiving plate 205 is pressed down, thereby compressing the spring 208 and moving it downward. The vacuum opens the press head 303 to hold the pin.

[0052] The press 301 moves upward, causing the press head 303 to move upward, removing the pin. The sliding receiving plate 205 is reset under the action of the spring 208. The second horizontal cylinder 203 retracts, causing the components on the sliding plate 204 to reset, so that the sliding receiving plate 205 leaves the bottom of the press 301.

[0053] The rotation of motor 101 causes the tooling on turntable 102 to rotate 60°. When photoelectric sensor 103 detects a signal from the product on the tooling, the first horizontal cylinder 401 extends, causing the ramp slide 402 to move out. The ramp slide 402 then moves the support column 403 upward to press against the lower surface of the tooling. Subsequently, the press 301 drives the press head 303 to descend, pressing the pin into the product on the tooling. The vacuum in the press head 303 is released, the press 301 moves upward to reset, and the first horizontal cylinder 401 resets, completing one cycle.

[0054] The preferred embodiments of this utility model have been described above. It should be understood that this utility model is not limited to the specific embodiments described above. Devices and structures not described in detail herein should be understood as being implemented in a conventional manner within the art. Any person skilled in the art can make many possible variations and modifications to the technical solutions of this utility model using the disclosed methods and techniques, or modify them into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. This does not affect the essential content of this utility model. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model, without departing from the content of the technical solution of this utility model, still fall within the protection scope of the technical solution of this utility model.
