[0025] The present application will be further described in detail below according to the drawings and embodiments.

[0026] ​The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0027] Example 1:

[0028] like Figure 4 As shown, the motherboard of the annular rubber pad contains several cut annular rubber pads. In assembly line production, the annular rubber pads need to be removed from the motherboard, transferred to the corresponding part to be processed, and then placed into the corresponding position on the part to be processed.

[0029] This embodiment provides a rubber pad picking and placing device. This device is used to fix and transfer an annular rubber pad when it is being extracted from a mother plate, and then to release the annular rubber pad, allowing it to detach. The picking and placing device mainly includes a hook part 1, a driving part 2, and a housing 3.

[0030] The hooking part 1 includes at least two sets of hooks 101, and the sets of hooks 101 surround a hooking center. Each set of hooks 101 has a hooking block 102 at its hooking end, and each set of hooking blocks 102 has a hooking surface 102-1. In this embodiment, as... Figures 1-3 As shown, preferably, it includes three sets of hooks 101. The drive unit 2 is connected to the connecting end of the hooks 101 and is used to drive the three sets of hooks 101 away from or towards the hooking center. The housing 3 is used to accommodate the hooking unit 1 and the drive unit 2. The working end 301 of the housing 3 has an extension opening so that the hooking block 102 extends out of the housing 3 through the extension opening. Figure 2 As shown, a first limiting space for accommodating an annular rubber pad is formed between the hook surface 102-1 and the working end 301.

[0031] Under this structure, the operation of the pick-and-place device is as follows:

[0032] First, the drive unit 2 drives all the hooks 101 close to the hooking center, forming a retracted state, ensuring that the hooking ends of all the hooks 101 can pass through the central hole of the annular rubber pad, and the three hooking blocks 102 can be placed on the back of the annular rubber pad. Then, the drive unit 2 drives the hooks 101 away from the hooking center, forming an open state. At this time, the hooking surfaces 102-1 on the three hooking blocks 102, the wall surface of the hooks 101 extending out of the outer opening, and the working end 301 together form a first limiting space. The part of the annular rubber pad near the central hole is placed within the first limiting space, thereby fixing the relative position between the pick-and-place device and the annular rubber pad. Meanwhile, in this embodiment, the three sets of hooks 101, when in the open state and in contact with the annular rubber pad, can provide support for the central hole of the annular rubber pad. This prevents the annular rubber pad from collapsing due to lack of support during transport, thus avoiding contact and adhesion between some rubber surfaces and preventing the annular rubber pad from becoming unusable in subsequent production. Finally, when it is necessary to detach the annular rubber pad, the drive unit 2 drives all the hooks 101 to approach the hooking center again, forming a closed state. This changes the first limiting space, allowing the portion of the annular rubber pad near the central hole to detach from the first limiting space, thereby realizing the detachment of the annular rubber pad from the self-removing device.

[0033] The drive unit 2 used can be any component or kit that can move the hook 101 away from or near the hooking center, such as a drive kit with a telescopic rod.

[0034] Preferably, such as Figures 2-3 As shown, the drive unit 2 includes a rotating block 201, a limiting block 202, and a drive device 203. In this embodiment, one end of the rotating block 201 is connected to the hook 101, and the other end is connected to the drive device 203. Therefore, the number of rotating blocks 201 should match the number of hooks 101. The limiting block 202 is fixed in the inner cavity of the housing 3. Several rotating blocks 201 are in contact with the guide protrusion 202-1 on the limiting block 202, so that when the drive device 203 pushes the rotating block 201 to slide relative to the limiting block 202, the other end of the rotating block 201 will drive the hook 101 away from or closer to the hooking center.

[0035] Preferably, the driving part 2 further comprises a homing auxiliary component 204, which is arranged between the rotating block 201 and the shell 3. When the driving part 2 no longer provides driving force or the driving force is insufficient, the homing auxiliary component 204 can provide driving force to drive the hook claw 101 to return to the original position. For example, when the driving part 2 is used to keep the hook claw 101 away from the hooking center to keep the open state, when the driving force stops providing driving force, the homing auxiliary component 204 can drive the hook claw 101 to approach the hooking center to return to the original state of the hook claw 101. In this way, the hook claw 101 can return to the normal state after completing the current work to smoothly carry out the next work. In the embodiment, the homing auxiliary component 204 can be an elastic component, a compression homing structure, etc.

[0036] Preferably, as shown in Figures 2-3 the homing auxiliary component 204 comprises an installation groove 204-1 arranged on the rotating block 201 and an elastic component 204-2 arranged in the installation groove 204-1. On the one hand, when the rotating block 201 approaches the shell 3 and the gap between the two decreases, the elastic component 204-2 can accumulate potential energy, and then release the potential energy to drive the rotating block 201 and the hook claw 101 to return to the original position after the driving device 203 stops providing driving force. On the other hand, in the embodiment, the elastic component 204-2 is an elastic ring, which can be embedded in several groups of rotating blocks 201 at the same time. As shown in Figure 3 three groups of rotating blocks 201 can be embedded in the same elastic ring through the installation groove 204-1. Therefore, when the three groups of rotating blocks 201 are driven by the driving part 2 to slide and the hook claw 101 is away from the hooking center, the elastic ring will also be expanded, and at this time, the elastic ring component will additionally generate a contraction force to subsequently push the rotating block 201 to return to the original position, thereby providing additional protection for the rotating block 201.

[0037] Preferably, as shown in Figures 2-3 the rotating block 201 is provided with an anti-friction protrusion 201-1, and the rotating block 201 will be in contact with the inner wall of the shell 3 through the anti-friction protrusion 201-1. In this structure, when the rotating block 201 slides relative to the limiting block 202, small-area contact friction will mainly occur between the anti-friction protrusion 201-1 and the inner wall of the shell 3, thereby reducing the friction force acting on the rotating block 201 and making the relative sliding of the rotating block 201 more smooth.

[0038] Preferably, as shown in Figure 2 the driving device 203 comprises a driving source 203-1 and a driving wedge 203-2, and the guide slope of the driving wedge 203-2 is in abutment with the rotating block 201, so that when the driving source 203-1 pushes the driving wedge 203-2, the guide slope will drive the rotating block 201 to slide along the guide convex surface 202-1. Figure 2For example, when the driving source 203-1 pushes the driving wedge 203-2 to move to the left, the guide slope will force the right ends of the three groups of rotating blocks 201 to move closer to each other, and at the same time, the claws 101 connected to the left ends of the rotating blocks 201 will be driven to move away from the hooking center, achieving the fixing effect of the annular rubber pad. Under this structure, the overall structure of the driving device 203 is simpler, which is conducive to subsequent maintenance and repair; the operation process is also relatively simple, avoiding the occurrence of power output failure caused by the non-response of some parts in the complex and precise structure during long-term use.

[0039] Preferably, the driving source 203-1 comprises an air-driven rod component. The air-driven rod component is a rod-shaped component driven by air pressure, which can accurately control the driving force output by controlling the air pressure under the premise of providing sufficient driving force. In the taking and placing device, the distance between the claws 101 and the hooking center can be accurately controlled, and different specifications of annular rubber pads can be effectively fixed without causing damage.

[0040] Preferably, the taking and placing device further comprises a guide part, which mainly comprises a guide groove arranged on the shell 3 and a guide block arranged on the driving device 203. The guide block is embedded in the guide groove, forming a restriction and guide for the moving path of the driving device 203.

[0041] Embodiment 2:

[0042] The rubber pad transfer device provided in this embodiment mainly comprises a rubber pad taking and placing device in embodiment 1 and a displacement kit for driving the rubber pad taking and placing device to move. The displacement kit can be any component or kit that can drive the rubber pad taking and placing device to move, such as a moving truss or a mechanical arm.

[0043] When the transfer device is running, first, the hooking block 102 of the rubber pad taking and placing device is controlled by the displacement kit to reach the required position for the fixing work in embodiment 1; then the rubber pad taking and placing device is used to fix the annular rubber pad, and the displacement kit is used to move the rubber pad taking and placing device and the fixed annular rubber pad, so as to take the annular rubber pad off the mother board; then the displacement kit is used to transfer the annular rubber pad to the subsequent processing point, and the rubber pad taking and placing device is controlled to make the annular rubber pad fall off smoothly, thereby completing the transfer work of the rubber pad once.

[0044] Finally, it should be noted that: the above implementation cases are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing implementation cases, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing implementation cases, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the present application.
