Description

Technical Field

[0001] This utility model relates to the field of robotic automated spraying technology, and in particular to a novel lifting device for single-ring workpieces on a suspended conveyor line. Background Technology

[0002] In the field of robotic automated painting, the focus is on the lifting and painting of "single-ring workpieces" (such as motors) on overhead conveyor lines. Currently, overhead conveyor lines are widely used for automated workpiece transport. However, single-ring workpieces such as motors, which have only one lifting point, require strict consistency in the incoming position and posture during robotic automated painting; otherwise, the painting effect will be affected.

[0003] Existing workpieces typically have only one lifting point, making it impossible to achieve circumferential rotation limit through multiple lifting points. This causes the same type of workpiece to sway and rotate easily on the suspended conveyor line, resulting in inconsistent material position and posture, which directly affects the accuracy of automatic spraying by the robot. Utility Model Content

[0004] The purpose of this utility model is to solve the problem in the prior art that the workpiece usually has only one lifting point, and it is impossible to achieve circumferential rotation limit through multiple lifting points, which leads to the same workpiece easily shaking and rotating on the suspended conveyor line, and inconsistent material position and posture. Therefore, a new type of lifting device for single-ring workpieces on the suspended conveyor line is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel lifting device for single-ring workpieces on a suspended conveyor line, comprising a horizontal lifting plate, a second shackle pinned to the bottom of the horizontal lifting plate near the center, a rotating lifting ring hanging from the bottom of the second shackle, a rotating iron plate fixedly installed at the bottom of the rotating lifting ring, a first hook fixedly installed at the bottom of the rotating iron plate, a vertical lifting plate sleeved on the surface of the first hook, a third shackle pinned to the bottom of the vertical lifting plate, and a second hook pinned to the bottom of the third shackle.

[0006] Preferably, a crossbeam is provided above the horizontal hanging plate, and a fixing hook is connected to the bottom of the crossbeam by a pin.

[0007] Preferably, the top of the horizontal hanging plate and near both ends are connected to a first shackle by a pin, and the first shackle is connected to a fixed hook hook.

[0008] Preferably, rotating handles are fixedly connected to both sides of the vertical hanging plate near the center.

[0009] Preferably, the surface of the vertical lifting plate is equipped with loading and unloading lifting rings.

[0010] Preferably, the surface of the vertical lifting plate is equipped with loading and unloading lifting rings.

[0011] Preferably, a swing arm is provided on one side of the rotating iron disc, and a ring magnet is connected to the bottom of the swing arm near the pins on both sides, and the top of the swing arm is connected to the top pin of the horizontal hanging plate.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the limiting effect of the swing arm and the circular magnet on the rotating iron disk, as well as the anti-relative rotation design between the components of the secondary lifting tool, can accurately ensure the consistency of the incoming position and posture of the single lifting ring workpiece, thus meeting the requirements of automatic spraying by the robot.

[0013] 2. In this utility model, one set of lifting tools can be adapted to all workpieces with a single lifting ring, eliminating the need to design special tooling for different workpieces and solving the problem of poor compatibility of existing tooling.

[0014] 3. In this utility model, a single person can complete the installation of the secondary lifting device and the workpiece during material loading using the auxiliary lifting device. When changing production, there is no need to replace the entire lifting device; only the posture of the workpiece needs to be adjusted, thus reducing the complexity of manual operation.

A swing rod 15 is provided on one side of the rotating iron plate 7, and a ring magnet 16 is connected to the bottom of the swing rod 15 near both sides by a pin. The top of the swing rod 15 is connected to the top of the horizontal hanging plate 1 by a pin.

[0022] The overall effect of embodiment 2 is as follows: a horizontal beam 4 is provided above the horizontal hanging plate 1, and a fixed hook 3 is connected to the bottom of the horizontal beam 4 by a pin, which can serve as a hanging tool; a first shackle 2 is connected to the top of the horizontal hanging plate 1 near both ends by a pin, and the first shackle 2 is hooked to the fixed hook 3, which can serve as a hanging tool for the horizontal hanging plate 1 to be suspended on the horizontal beam 4; a rotating handle 10 is fixedly connected to both sides of the vertical hanging plate 9 near the center, which can serve as a tool for adjusting the rotation direction of the workpiece; a loading and unloading lifting ring 11 is installed on the surface of the vertical hanging plate 9, which can serve as a tool for facilitating loading and unloading; a part to be painted 14 is sleeved on the surface of the second hook 13, which can serve as a tool for hanging the part to be painted 14 on the second hook 13; a swing rod 15 is provided on one side of the rotating iron plate 7, and a circular magnet 16 is connected to the bottom of the swing rod 15 near both sides by a pin, and the top of the swing rod 15 is connected to the top of the horizontal hanging plate 1 by a pin, which can serve as a tool for limiting the rotation of the rotating iron plate 7.

[0023] Working principle: The first shackle 2 near both ends of the top of the horizontal lifting plate 1 is connected to the fixed hook 3 at the bottom of the crossbeam 4 to fix the lifting device to the suspension line. The second shackle 5 is connected to the bottom of the horizontal lifting plate 1 near the center by a pin. The bottom of the second shackle 5 is hung with a rotating lifting ring 6. The bottom of the rotating lifting ring 6 is fixedly installed with a rotating iron plate 7. The bottom of the rotating iron plate 7 is fixedly installed with a first hook 8. At the same time, the top of the swing rod 15 is connected to the top pin of the horizontal lifting plate 1, and the bottom of the swing rod 15 near both sides is connected with a ring magnet 16 to complete the overall assembly of the lifting device. At this point, the vertical hanging plate 9 is fitted onto the surface of the first hook 8 (the long U-shaped hole design of the vertical hanging plate 9 ensures convenient hanging and retrieval, and the vertical hanging plate 9 and the first hook 8 do not rotate relative to each other under the action of gravity). The rotating handle 10 is fixedly connected to both sides of the vertical hanging plate 9 near the center, and the loading and unloading lifting ring 11 is installed on the surface. The bottom of the vertical hanging plate 9 is connected to the third shackle 12 through a pin, and the bottom pin of the third shackle 12 is connected to the second hook 13. The part to be painted 14 is fitted onto the surface of the second hook 13 (the second hook 13 and the lifting ring of the part to be painted 14 do not rotate relative to each other). In use, a person manually holds the auxiliary lifting device and uses the loading / unloading lifting ring 11 to suspend the secondary lifting tool, which is equipped with the part to be painted 14, on the first hook 8, and then removes the auxiliary lifting device. The person then manually rotates the rotating handle 10, which drives the vertical lifting plate 9, the third shackle 12, the second hook 13, and the part to be painted 14 to rotate synchronously until the output shaft of the part to be painted 14 faces the designated position. Then, the person moves the swing arm 15, which rotates around its top pin until the bottom ring magnet 16 is attracted to the side of the rotating iron plate 7. The magnetic force restricts the rotation of the rotating iron plate 7, thereby fixing the posture of the first hook 8, the secondary lifting tool, and the part to be painted 14, ensuring the stability of the position and posture of the part to be painted 14 during the transportation process, and meeting the requirements of automatic spraying by the robot. When unloading or reloading, the person moves the swing arm 15, which causes the ring magnet 16 to detach from the rotating iron plate 7, and then the part to be painted 14 can be rotated to adjust its posture or the workpiece can be removed, completing the entire operation process.

[0024] The wiring diagrams of the second shackle 5 and the part to be painted 14 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring arrangement of the second shackle 5 and the part to be painted 14 will not be explained in detail.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
