Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping technology, specifically a multi-segment clamp. Background Technology
[0002] Electroplating is a process that uses the principle of electrolysis to plate a thin layer of other metals or alloys onto the surface of certain metals, thereby improving wear resistance, conductivity, reflectivity, corrosion resistance, and aesthetics.
[0003] When electroplating products, the products need to be placed on a rack and the rack is immersed in the electroplating solution. After electroplating is completed, the rack needs to be removed. Traditional racks are usually moved by a lifting device. During the transfer of the rack, it is quite shaky, which may cause the products to collide and be damaged or even fall off, affecting the product quality. In addition, the connection between the rack and the lifting device is unstable, which may pose safety hazards such as the rack falling off. Utility Model Content
[0004] The technical problem solved by this utility model is to provide a multi-segment fixture to address the issues raised in the background section.
[0005] The technical problem solved by this utility model is achieved by the following technical solution: a multi-segment clamp for lifting product hangers, including a clamp seat and a first clamp and a second clamp adjustablely installed on both sides of the clamp seat. A frame plate is fixedly provided at the upper middle part of the clamp seat, and a flange plate is fixedly provided on the frame plate and installed at the end of the robot arm through the flange plate.
[0006] The first clamp and the second clamp are slidably mounted on both sides of the frame plate. The clamp seat is equipped with a first stroke cylinder for driving the first clamp to move and a second stroke cylinder for driving the second clamp to move. The first stroke cylinder and the second stroke cylinder are double stroke cylinder structures to achieve multi-stage displacement.
[0007] The first clamp includes a frame slidably sleeved on the outer end of the clamp seat and brackets fixedly installed on both sides of the lower end of the frame. A pressing cylinder is also provided between the two brackets on the frame. A pressure frame is fixedly installed at the lower end of the output rod of the pressing cylinder. The pressure frame and the bracket cooperate to clamp and fix the hanging rod at the upper end of the product hanger. Flat pressure plates are also provided on both sides of the upper end of the pressure frame to abut against the upper end of the product hanger and maintain the stability of the product hanger. The second clamp has the same structure as the first clamp.
[0008] As a further embodiment of this utility model:
[0009] The upper end of the clamp is provided with slide rails on both sides corresponding to the first clamp and the second clamp respectively. Slider is installed on both sides of the frame and is slidably mounted on the slide rails through the slider. The lower end of the clamp is provided with a displacement groove corresponding to the frame. A support plate is provided on the frame through the displacement groove. The output rod of the first stroke cylinder is connected to the support plate on the first clamp to control the sliding of the first clamp. The output rod of the second stroke cylinder is connected to the support plate on the second clamp to control the sliding of the second clamp. The first stroke cylinder and the second stroke cylinder are arranged alternately to control the first clamp and the second clamp to move synchronously in opposite directions or in opposite directions respectively.
[0010] As a further embodiment of this utility model:
[0011] A first clamping block is fixedly installed on one side of the lower end of the bracket, and a second clamping block is provided on each side of the pressure frame corresponding to the first clamping block. The first clamping block cooperates with the second clamping block to clamp and fix the hanging rod at the upper end of the product hanger. A V-shaped clamping groove is provided on the corresponding side of the first clamping block and the second clamping block to prevent the hanging rod from falling off.
[0012] As a further embodiment of this utility model:
[0013] The brackets on the first and second clamps are symmetrically arranged, and the first clamping blocks on the first and second clamps are located on the side away from the shelf.
[0014] As a further embodiment of this utility model:
[0015] The flat pressure plate has a Y-shaped structure with one side being bent. It is bolted to the upper end of the pressure frame so that the outer end of the flat pressure plate is pressed down with the pressure frame and rests against the upper end of the product hanger, reducing the shaking of the product hanger during hoisting and improving stability.
[0016] Compared with existing technologies, the beneficial effects of this utility model are as follows: The robotic arm moves the clamping seat to the corresponding position via the flange plate. The first and second stroke cylinders inside the clamping seat operate synchronously to control the first and second clamping frames to move to opposite sides. The robotic arm then controls the first and second clamping frames to descend, allowing the bracket to insert into the upper gap of the product hanger. The first and second stroke cylinders operate again, positioning the first clamping block at the lower end of the hanging rod. The pressing cylinder controls the pressure frame to descend, and the hanging rod is clamped and fixed by the second clamping block in conjunction with the first clamping block. The pressure frame drives the flat pressure plate to abut against the upper end of the product hanger, stabilizing the product hanger and allowing it to be stably moved into or out of the electroplating tank. This device, automatically controlled by the robotic arm, can achieve segmented operation. The multi-segment clamps can quickly dock with and release the product hanger, improving work efficiency. The multi-segment clamps can stably hold the product hanger, reducing damage during the electroplating transfer process. It is suitable for mass production, reducing enterprise production costs.

A frame plate 11 is fixedly provided at the upper middle part of the clamping seat 1, and a flange plate 12 is fixedly provided on the frame plate 11 and installed at the end of the robot arm through the flange plate 12.
[0024] The first clamp 2 and the second clamp 3 are slidably installed on both sides of the frame plate 11. The clamp seat 1 is provided with a first stroke cylinder 13 for driving the first clamp 2 to move and a second stroke cylinder 14 for driving the second clamp 3 to move.

[0025] The first clamp 2 includes a frame 21 slidably sleeved on the outer end of the clamp 1 and brackets 22 fixedly installed on both sides of the lower end of the frame 21. The frame 21 is also provided with a pressing cylinder 23 between the two brackets 22. The lower end of the output rod of the pressing cylinder 23 is fixedly installed with a pressure frame 24. The pressure frame 24 and the brackets 22 cooperate to clamp and fix the hanging rod 41 at the upper end of the product hanger 4. The upper ends of the pressure frame 24 are also provided with flat pressure plates 5, so that the flat pressure plates 5 abut against the upper end of the product hanger 4 to keep the product hanger 4 stable. The second clamp 3 has the same structure as the first clamp 2.
[0026] In this embodiment, slide rails 15 are respectively provided on both sides of the upper end of the clamping seat 1 corresponding to the first clamp 2 and the second clamp 3. Slider 25 is installed on both sides of the frame 21 and is slidably mounted on the slide rails 15 through the slider 25. The lower end of the clamping seat 1 is provided with a displacement groove 16 corresponding to the frame 21. A support plate 26 passing through the displacement groove 16 is provided on the frame 21. The output rod of the first stroke cylinder 13 is connected to the support plate 26 on the first clamp 2 to control the sliding of the first clamp 2. The output rod of the second stroke cylinder 14 is connected to the support plate 26 on the second clamp 3 to control the sliding of the second clamp 3. The first stroke cylinder 13 and the second stroke cylinder 14 are arranged alternately to control the first clamp 2 and the second clamp 3 to move synchronously in opposite directions or in opposite directions.
[0027] In this embodiment, a first clamping block 27 is fixedly installed on one side of the lower end of the bracket 22. The pressure frame 24 is provided with second clamping blocks 28 on both sides corresponding to the first clamping block 27. The first clamping block 27 cooperates with the second clamping block 28 to clamp and fix the hanging rod 41 at the upper end of the product hanger 4. The first clamping block 27 and the second clamping block 28 are provided with V-shaped clamping grooves 29 on their respective sides to prevent the hanging rod 41 from falling off.
[0028] The brackets 22 on the first clamp 2 and the second clamp 3 are symmetrically arranged, and the first clamping block 27 on the first clamp 2 and the second clamp 3 is located on the side away from the frame plate 11.
[0029] In this embodiment, the flat pressure plate 5 has a Y-shaped structure, one side of which is bent and is bolted to the upper end of the pressure frame 24 so that the outer end of the flat pressure plate 5 is pressed down with the pressure frame 24 and abuts against the upper end of the product hanger 4, thereby reducing the shaking of the product hanger 4 during hoisting and improving stability.
[0030] Specifically, the robot arm moves the clamping seat 1 to the corresponding position via the flange plate 12. The first stroke cylinder 13 and the second stroke cylinder 14 inside the clamping seat 1 act synchronously to control the first clamping frame 2 and the second clamping frame 3 to move to opposite sides. The robot arm then controls the first clamping frame 2 and the second clamping frame 3 to descend, so that the bracket 22 is inserted into the upper gap of the product hanger 4. The first stroke cylinder 13 and the second stroke cylinder 14 act again, so that the first clamping block 27 is located at the lower end of the hanging rod 41. The pressing cylinder 23 controls the pressing frame 24 to descend. The second clamping block 28 cooperates with the first clamping block 27 to clamp and fix the hanging rod 41. The pressing frame 24 drives the flat pressure plate 5 to abut against the upper end of the product hanger 4, stabilizing the product hanger 4, so that the product hanger 4 can be stably moved into or out of the electroplating tank. This device is automatically controlled by a robotic arm and can perform segmented movements. Utilizing a multi-segment clamp, it can quickly dock with and detach from the product holder 4, improving work efficiency. The multi-segment clamp also ensures the product holder 4 is held securely, reducing damage during the electroplating and transfer process. It is suitable for mass production, reducing enterprise production costs.
