Description

Technical Field

[0001] This utility model relates to the field of electroplating processing technology, specifically an automated transfer device for electroplating racks. Background Technology

[0002] For some metal parts, electroplating is often necessary to achieve purposes such as rust prevention and improved surface gloss. In the automatic electroplating process, the racks holding the workpieces to be electroplated need to be manually hung in the electroplating tank, and after electroplating is completed, the racks are manually transferred out of the electroplating tank.

[0003] However, during the aforementioned transfer process, the hanging and lowering of the electroplating racks still requires manual operation, leaving operators still in the electroplating environment. This is not only inefficient and labor-intensive, but also harmful to the health of the operators, hindering the development of the electroplating industry. Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide an automated transfer device for electroplating racks to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automated transfer device for electroplating racks includes a fixed base, on which a robotic arm mechanism is mounted. A rotating arm is mounted at the output end of the robotic arm mechanism, and a drive box is fixedly mounted at the bottom of the rotating arm. A guide shaft is symmetrically fixedly mounted inside the drive box, and a horizontal pushing claw is slidably mounted on the guide shaft. The horizontal pushing claw passes through the drive box and is positioned outside the drive box. A fixed plate is symmetrically fixedly mounted on the outer wall of the drive box at a position corresponding to the horizontal pushing claw. Upper and lower pushing claws are rotatably mounted on the fixed plate via a rotating part. The drive box is equipped with a pushing mechanism for driving the horizontal pushing claw and the upper and lower pushing claws to move synchronously.

The pushing mechanism also includes a pushing component.

[0010] As an improvement of this utility model: the pushing assembly includes a pushing inclined block fixed on a horizontal pushing claw, a pushing ball contacting one side of the inclined surface of the pushing inclined block, the pushing ball being fixed at both ends of the horizontal frame, and a pushing spring being sleeved and installed on the guide shaft of the drive box between the horizontal pushing claw and the inner wall of the drive box.

[0011] As an improvement of this utility model, a stop block is fixedly installed on the side of the guide shaft away from the inner wall of the drive box.

[0012] As an improvement of this utility model: the two ends of the horizontal pushing claw and the lower side of the upper and lower pushing claws are respectively provided with claw grooves, and the upper side of the horizontal pushing claw and the lower side of the upper and lower pushing claws are respectively provided with claw blocks near the claw groove area.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] Example 1: See Figures 1-6In this embodiment of the utility model, an automated transfer device for electroplating racks includes a fixed base 1, a robotic arm mechanism mounted on the fixed base 1, a rotating arm 5 mounted on the output end of the robotic arm mechanism, a drive box 6 fixedly mounted at the bottom of the rotating arm 5, a guide shaft 16 symmetrically fixedly mounted inside the drive box 6, a horizontal pushing claw 8 slidably mounted on the guide shaft 16, the horizontal pushing claw 8 passing through the drive box 6 and positioned outside the drive box 6, a fixed plate 20 symmetrically fixedly mounted on the outer wall of the drive box 6 at a position corresponding to the horizontal pushing claw 8, upper and lower pushing claws 9 rotatably mounted on the fixed plate 20 via a rotating part, and a pushing mechanism for driving the horizontal pushing claw 8 and the upper and lower pushing claws 9 to move synchronously inside the drive box 6.

[0028] The robotic arm mechanism in this transfer device includes a rotating arm 2 rotatably mounted on a fixed base 1, a large arm 3 mounted on the rotating arm 2, a small arm 4 rotatably mounted on the large arm 3, and a rotating arm 5 mounted on the small arm 4. Each of the large arm 3, small arm 4, and rotating arm 5 is equipped with a corresponding steering motor, thereby ensuring the degree of freedom of the entire robotic arm mechanism.

[0029] To ensure that the upper and lower push claws 9 can be reset to a horizontal position when not in operation, the rotating part in this embodiment includes a rotating shaft 21 fixedly installed between the fixed plates 20. The upper and lower push claws 9 are rotatably installed on the rotating shaft 21, and a torsion spring 22 is installed on the rotating shaft 21 between the upper and lower push claws 9 and the fixed plate 20.

[0030] In one embodiment, the pushing mechanism includes a pushing cylinder 10 installed inside the drive box 6. The pushing cylinder 10 can be a pneumatic cylinder or a hydraulic cylinder, so that it can quickly respond to the transfer work of the transfer device. The output end of the pushing cylinder 10 is connected to a pushing shaft 11. A horizontal frame 12 is fixedly installed at the end of the pushing shaft 11. A limiting shaft 15 is fixedly installed on the horizontal frame 12. The limiting shaft 15 passes through the drive box 6 and a limiting ball 23 is fixedly installed. The limiting ball 23 is in contact with one side of the inclined end of the upper and lower pushing claws 9. The pushing mechanism also includes a pushing component.

[0031] The pushing assembly includes a pushing block 14 fixed on a horizontal pushing claw 8. One side of the inclined surface of the pushing block 14 contacts a pushing ball 13. The pushing ball 13 is fixed at both ends of the horizontal frame 12. A pushing spring 17 is also sleeved on the guide shaft 16 of the drive box 6 between the horizontal pushing claw 8 and the inner wall of the drive box 6.

[0032] When the push cylinder 10 is activated, the push shaft 11 extends and retracts to the front end. On one hand, this drives the horizontal frame 12 so that the push ball 13 abuts against the inclined side of the push block 14. Under the guidance of the guide shaft 16, the two horizontal push claws 8 move linearly towards the inner wall of the drive box 6. On the other hand, under the action of the limiting shaft 15, the limiting ball 23 abuts against the upper inclined side of the upper and lower push claws 9, causing the upper and lower push claws 9 to move downward along the rotation shaft 21.

[0033] In addition, in order to ensure that the horizontal pusher 8 will not detach from the guide shaft 16 under the elastic force of the pusher spring 17, a stop block 7 is fixedly installed on the side of the guide shaft 16 away from the inner wall of the drive box 6.

[0034] Example 2: In another embodiment of this utility model, the difference from the above embodiment is that, respectively, claw grooves 18 are provided at both ends of the horizontal pushing claw 8 and at the lower side of the upper and lower pushing claws 9, and claw blocks 19 are provided on the upper side of the horizontal pushing claw 8 and the lower side of the upper and lower pushing claws 9 near the claw grooves 18. The cooperation of the claw grooves 18 and the claw blocks 19 allows the horizontal pushing claw 8 and the upper and lower pushing claws 9 to better push against the electroplating rack, further ensuring the stability of the electroplating rack during transport.

[0035] In summary, when the electroplating racks within the electroplating tank need to be transferred, a robotic arm mechanism engages the upper and lower push claws 9 and the horizontal push claws 8 within the two crossbars at the top of the electroplating rack. Simultaneously, the push cylinder 10 is activated, causing the push shaft 11 to extend and retract forward. Under the action of the push mechanism, the two horizontal push claws 8 move continuously towards the sides of the electroplating rack, while the front end of one of the upper and lower push claws 9 moves downward. Ultimately, the two horizontal push claws 8 are positioned on either side of the upper crossbar of the electroplating rack, while the upper and lower push claws 9 are positioned in the middle of the lower crossbar, ensuring the stability of the entire electroplating rack during transfer. Once the transfer is complete, the push cylinder 10 is activated in reverse, causing the push shaft 11 to retract, thus disengaging the upper and lower push claws 9 and the horizontal push claws 8 from the electroplating rack. The electroplating rack is then secured to the transfer position using two hooks on the rack. The entire transfer process is quick, convenient, and highly automated.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
