Abstract
Description
Technical Field
[0001] This application belongs to the field of electroplating technology, and more specifically, relates to a clamping mechanism and electroplating equipment. Background Technology
[0002] In the process of electroplating sheet materials, it is generally necessary to use clamps to hold the sheet materials in a specific position. For example, when electroplating glass substrates, it is necessary to use clamps to fix the glass substrates on the hanger.
[0003] In traditional electroplating equipment, the clamps primarily use a rotary opening and closing mechanism to hold and release the sheet metal. The jaws rotate around a fixed axis, changing the angle between them to accommodate the insertion and clamping of the sheet metal. However, this rotary opening and closing mechanism is limited by the rotation trajectory and mechanical structure, significantly restricting the maximum opening angle and thus failing to provide sufficient operating space. This can easily cause interference between the sheet metal and the clamp during loading and unloading, making the process inconvenient. Utility Model Content
[0004] In order to overcome the problems existing in the prior art, the main objective of this application is to provide a clamping mechanism and an electroplating device.
[0005] To achieve the above objectives, this application specifically adopts the following technical solution:
[0006] According to a first aspect of the embodiments of this application, a clamping mechanism is provided, comprising:
[0007] The first gripper has a first gripping surface;
[0008] The second gripper has a second gripping surface; the second gripping surface faces the first gripping surface and is set at a preset angle to the first gripping surface;
[0009] The fastener is connected to the first gripper; and
[0010] The movable component is connected to the second gripper and movably connected to the fixing member. When the movable component moves relative to the fixing member, it drives the second gripper to move between the closed position and the open position with the preset angle remaining unchanged. In the closed position, the second clamping surface is arranged opposite to the first clamping surface for clamping the plate. In the open position, the second clamping surface is misaligned with the first clamping surface, so that the first clamping surface is fully exposed.
[0011] Optionally, the clamping mechanism further includes a reset member, which connects the fixed member and the movable component, and the reset member is used to provide a force that causes the movable component to move the second gripper from the open position to the closed position.
[0012] Optionally, the movable component includes a first linkage, a second linkage, and a third linkage. The first linkage and the third linkage are arranged parallel to each other and spaced apart. The second linkage and the fixing member are arranged parallel to each other and spaced apart. One end of the first linkage, the second linkage, the third linkage, the fixing member, and the other end of the first linkage are sequentially hinged together. The second linkage is connected to the second gripper.
[0013] Optionally, the third linkage member is hinged to the end of the second linkage member away from the second gripper, and the clamping mechanism further includes a reset member, which connects the third linkage member and the fixing member.
[0014] Optionally, the fixing member is provided with a protrusion, the protrusion is provided with a limiting groove, the movable component further includes a connecting shaft, the connecting shaft is movably passed through the protrusion and the third linkage member, the reset member is a torsion spring, the torsion spring is housed in the limiting groove and sleeved on the connecting shaft, and the two ends of the torsion spring respectively abut against the fixing member and the third linkage member.
[0015] Optionally, the third linkage is hinged to the end of the second linkage away from the second gripper, and the movable component further includes a pressing member connected to the third linkage.
[0016] Optionally, the preset angle between the second clamping surface and the first clamping surface is 0°.
[0017] Optionally, the first clamping surface is provided with a first buffer pad; and / or, the second clamping surface is provided with a second buffer pad.
[0018] Optionally, the outer surface of the first gripper is provided with a first insulating layer; and / or, the outer surface of the second gripper is provided with a second insulating layer.
[0019] According to a second aspect of the embodiments of this application, an electroplating apparatus is provided, including the clamping mechanism described in any of the preceding claims.
[0020] The advantages of the clamping mechanism and electroplating equipment provided in this application are as follows: Compared with the prior art, when the movable component moves relative to the fixed member, the clamping mechanism provided in this application drives the second gripper to move between the closed position and the open position with the preset angle remaining unchanged, thereby realizing the action of clamping or releasing the plate. Since the second clamping surface is misaligned with the first clamping surface in the open position, the first clamping surface is completely exposed, forming an unobstructed picking and placing space on the facing side of the first clamping surface. Thus, the plate can be placed directly and smoothly on the first clamping surface or removed from the first clamping surface through the picking and placing space, effectively avoiding interference between the plate and the second gripper during picking and placing, significantly improving the convenience and safety of operation, and is suitable for fragile plates such as glass substrates.
[0021] Furthermore, since the preset angle between the second clamping surface and the first clamping surface remains unchanged during the relative movement of the second clamping jaws to the first clamping jaws, the clamping angle between the first clamping surface and the second clamping surface on the plate does not change when clamping plates of various thicknesses. This allows both the first clamping surface and the second clamping surface to make full contact with the opposite sides of the plate, thereby achieving stable and reliable clamping of plates of various thicknesses and effectively preventing deformation and cracking of the glass substrate due to local stress concentration.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0033] Please refer to the following: Figures 1 to 3 The clamping mechanism provided in the embodiments of this application will now be described. The clamping mechanism is used to clamp materials such as glass substrates.
[0034] Please see Figure 1 and Figure 2The clamping mechanism includes a first gripper 10, a second gripper 20, a fixing member 30, and a movable component 40. The first gripper 10 has a first clamping surface 11; the second gripper 20 has a second clamping surface 21; the second clamping surface 21 faces the first clamping surface 11 and is set at a preset angle with the first clamping surface 11; the fixing member 30 is connected to the first gripper 10; the movable component 40 is connected to the second gripper 20 and is movably connected to the fixing member 30; when the movable component 40 moves relative to the fixing member 30, it drives the second gripper 20 to move between a closed position and an open position with the preset angle remaining unchanged; in the closed position, the second clamping surface 21 is set opposite to the first clamping surface 11 for clamping the plate; in the open position, the second clamping surface 21 is misaligned with the first clamping surface 11, so that the first clamping surface 11 is fully exposed.
[0035] The second clamping surface 21 being positioned opposite to the first clamping surface 11 means that the orthographic projection of the second clamping surface 21 at least partially coincides with the orthographic projection of the first clamping surface 11. The second clamping surface 21 being misaligned with the first clamping surface 11 means that the orthographic projection of the second clamping surface 21 does not coincide with the orthographic projection of the first clamping surface 11, resulting in the first clamping surface 11 being completely exposed.
[0036] For example, the clamping mechanism is placed horizontally with the first clamping surface 11 facing upwards, and the substrate is a glass substrate. When the clamping mechanism is not clamping the glass substrate, the second gripper 20 is in the closed position, that is, the second clamping surface 21 and the first clamping surface 11 are arranged parallel to each other in the vertical direction. When it is necessary to clamp the glass substrate, the driving movable component 40 moves relative to the fixed component 30, and the movable component 40 drives the second gripper 20 to move from the closed position to the open position with a preset angle that remains unchanged. At this time, the second clamping surface 21 and the first clamping surface 11 are misaligned, so that the first clamping surface 11 is completely exposed, thereby forming an unobstructed picking and placing space above the first clamping surface 11. The operator or robotic arm can place the part of the glass substrate to be clamped from the picking and placing space onto the first clamping surface 11. After the glass substrate is placed in position, the drive assembly 40 moves in the opposite direction to the fixed member 30. The drive assembly 40 then moves the second gripper 20 from the open position to the closed position at a preset angle. At this time, the second clamping surface 21 and the first clamping surface 11 are positioned opposite each other, and a gap adapted to the thickness of the glass substrate is formed between them to clamp the glass substrate. When it is necessary to unload the glass substrate, the drive assembly 40 moves the second gripper 20 from the closed position to the open position again, and then the glass substrate placed on the first clamping surface 11 is directly removed through the pick-and-place space.
[0037] Compared with the prior art, the clamping mechanism provided in this application, when the movable component 40 moves relative to the fixed component 30, drives the second gripper 20 to move between the closed position and the open position with a preset angle that remains unchanged, thereby realizing the action of clamping or releasing the plate. Since the second clamping surface 21 is misaligned with the first clamping surface 11 in the open position, the first clamping surface 11 is completely exposed, so as to form an unobstructed picking and placing space on the facing side of the first clamping surface 11. Thus, the plate can be placed directly and smoothly on the first clamping surface 11 or removed from the first clamping surface 11 through the picking and placing space, effectively avoiding interference between the plate and the second gripper 20 during picking and placing, significantly improving the convenience and safety of operation, and is suitable for fragile plates such as glass substrates. Furthermore, since the preset angle between the second clamping surface 21 and the first clamping surface 11 remains unchanged during the relative movement of the second clamping jaw 20 relative to the first clamping jaw 10, the clamping angle of the first clamping surface 11 and the second clamping surface 21 on the plate does not change when clamping plates of various thicknesses. This allows the first clamping surface 11 and the second clamping surface 21 to make full contact with the opposite sides of the plate, thereby achieving stable and reliable clamping of plates of various thicknesses and effectively preventing deformation and cracking of the glass substrate due to local stress concentration.
[0038] Combined with appendix Figure 1 and Figure 2 The preset angle between the first clamping surface 11 and the second clamping surface 21 is set according to the shape of the board. Optionally, the preset angle between the first clamping surface 11 and the second clamping surface 21 is 0°. It can be understood that the second clamping surface 21 is arranged parallel to the first clamping surface 11 and is used to clamp boards with uniform thickness.
[0039] Combined with appendix Figures 1 to 3 It is understood that the clamping mechanism also includes a reset member 50, which connects the fixed member 30 and the movable component 40. The reset member 50 is used to provide a force that causes the movable component 40 to drive the second gripper 20 from the open position to the closed position.
[0040] The above technical solution, by setting a reset member 50, allows the second gripper 20 to automatically return to the closed position from the open position after the external force on the movable component 40 is removed when the second gripper 20 is in the open position. This eliminates the need for additional manual operation or continuous application of driving force, greatly simplifying the operation process and improving ease of use. Furthermore, during the clamping process, the force continuously provided by the reset member 50 can be converted into a continuous pre-tightening force on the plate by the second gripper 20, ensuring that the second clamping surface 21 and the first clamping surface 11 stably adhere to the opposite sides of the plate.
[0041] Combined with appendix Figure 1 and Figure 2 It is understood that the active component 40 includes a first linkage 41, a second linkage 42 and a third linkage 43. The first linkage 41 and the third linkage 43 are arranged in parallel and spaced apart. The second linkage 42 and the fixing member 30 are arranged in parallel and spaced apart. One end of the first linkage 41, the second linkage 42, the third linkage 43, the fixing member 30 and the other end of the first linkage 41 are hinged in sequence, and the second linkage 42 is connected to the second gripper 20.
[0042] Specifically, one end of the first linkage 41 is hinged to the fixed member 30 near the first gripper 10, and the other end of the first linkage 41 is hinged to the end of the second linkage 42 near the second gripper 20; one end of the third linkage 43 is hinged to the fixed member 30 away from the first gripper 10, and the other end of the third linkage 43 is hinged to the end of the second linkage 42 away from the second gripper 20, so that the first linkage 41, the second linkage 42, the third linkage 43 and the fixed member 30 together constitute a parallelogram linkage structure.
[0043] For example, when the third linkage 43 is driven to rotate relative to the fixed member 30 around the hinge point between the third linkage 43 and the fixed member 30, according to the characteristics of the parallelogram linkage structure, the rotation of the third linkage 43 will synchronously drive the second linkage 42 to maintain a parallel position relationship with the fixed member 30 and perform corresponding movements. In turn, the second linkage 42 drives the second gripper 20 to move between the closed position and the open position with a preset angle that remains unchanged.
[0044] By using a parallelogram linkage structure to drive the second gripper 20 to move between the closed and open positions, the preset angle remains unchanged. At the same time, the movement of the second gripper 20 is smooth and reliable, reducing swaying and deviation during the movement. This allows the first clamping surface 11 and the second clamping surface 21 to make accurate and stable full contact with the plate, ensuring the accuracy and stability of the plate clamping.
[0045] It should be noted that the length and other parameters of the second gripper 20 and the second linkage 42 are adjusted according to the actual working conditions to ensure that the second clamping surface 21 can fully contact the plate with the maximum contact range.
[0046] Combined with appendix Figures 1 to 3It is understood that the movable component 40 also includes a pressing member 44, which is connected to the third linkage member 43. When the pressing member 44 is pressed towards the fixed member 30, the pressing member 44 drives the third linkage member 43 to rotate around the hinge point between the third linkage member 43 and the fixed member 30 towards the fixed member 30. It is understood that by connecting the pressing member 44 to the third linkage member 43, the operator or robotic arm can directly drive the third linkage member 43 to move by operating the pressing member 44, providing a clear and convenient point for applying force to drive the third linkage member 43 to move, thus improving the ease of operation.
[0047] Optionally, one end of the pressing member 44 is connected to the end of the third linkage member 43 near the second linkage member 42, so that the pressing member 44 is away from the hinge point between the third linkage member 43 and the fixing member 30. Thus, when an external force is applied to the pressing member 44, the first linkage member 41 and the second linkage member 42 can be stably driven by the third linkage member 43 to generate linkage, ensuring that the second linkage member 42 always remains parallel to the fixing member 30, thereby keeping the preset angle between the second clamping surface 21 and the first clamping surface 11 constant.
[0048] Optionally, the pressing component 44 and the third linkage component 43 are integrally formed. The integrally formed structure effectively ensures the connection strength between the pressing component 44 and the third linkage component 43, and eliminates the need for additional assembly processes, reducing the number of parts and assembly time, and significantly improving production efficiency. Of course, the pressing component 44 can also be connected to the third linkage component 43 by screws or welding.
[0049] Combined with appendix Figure 3 It is understandable that the reset member 50 connects the third linkage member 43 and the fixing member 30. When the second gripper 20 needs to move from the closed position to the open position, an external force is applied to the third linkage member 43. The third linkage member 43 drives the first linkage member 41 and the second linkage member 42 to move together. In turn, the second linkage member 42 drives the second gripper 20 from the closed position to the open position. The reset member 50 deforms and stores elastic potential energy. After the external force on the third linkage member 43 is removed, the reset member 50 releases the elastic potential energy and automatically drives the third linkage member 43 to move in the opposite direction. The third linkage member 43, through the second linkage member 42, drives the second gripper 20 from the open position to the closed position. By connecting the reset member 50 to the third linkage member 43 and the fixing member 30, the layout is reasonable, the structure is compact, and the assembly is convenient. Of course, alternatively, the reset member 50 can be connected to the first linkage member 41 and the fixing member 30, or the reset member 50 can be connected to the second linkage member 42 and the fixing member 30.
[0050] Combined with appendix Figure 3It is understood that the fixing member 30 is provided with a protrusion 31, and the protrusion 31 is provided with a limiting groove 32. The movable component 40 also includes a connecting shaft 45, which is movably inserted through the protrusion 31 and the third linkage member 43, so that one end of the third linkage member 43 is hinged to the fixing member 30. The reset member 50 is a torsion spring, which is housed in the limiting groove 32 and sleeved on the connecting shaft 45, and the two ends of the torsion spring abut against the fixing member 30 and the third linkage member 43 respectively.
[0051] The above technical solution, through the cooperation of the limiting groove 32 and the connecting shaft 45, limits the torsion spring, effectively preventing the torsion spring from shifting or falling off during operation, ensuring the stability and reliability of the entire clamping mechanism structure, and enabling the reset component 50 to function continuously and stably. Furthermore, by housing the torsion spring within the limiting groove 32, the reset component 50 is internally integrated, effectively reducing the overall size of the clamping mechanism.
[0052] Of course, the reset component 50 can also be a tension spring or a spring sheet, etc.
[0053] Combined with appendix Figure 4 Alternatively, the movable component 40 includes an adapter rod 41a, a telescopic rod 42a, and a movable rod 43a. The adapter rod 41a and the fixing member 30 are arranged parallel to each other in the vertical direction, and the length direction of the adapter rod 41a is consistent with the length direction of the fixing member 30. One end of the adapter rod 41a is connected to the second gripper 20. The telescopic rod 42a is arranged vertically, and the bottom of the telescopic rod 42a is fixedly connected to the fixing member 30. The top of the telescopic rod 42a slides horizontally with the adapter rod 41a. When the movable rod 43a is hinged to the bottom of the fixed member 30, and the middle part of the movable rod 43a is hinged to the end of the adapter rod 41a away from the second gripper 20, when the movable rod 43a rotates around the hinge point between the movable rod 43a and the fixed member 30, the adapter rod 41a drives the second gripper 20 to generate horizontal and vertical displacement relative to the first gripper 10, so that the second gripper 20 switches between the closed position and the open position. During the movement of the adapter rod 41a, the telescopic rod 42a extends and retracts adaptively.
[0054] Combined with appendix Figure 1 and Figure 2 It is understood that the first clamping surface 11 is provided with a first buffer pad 60. During the clamping operation of the second clamping surface 21 and the first clamping surface 11, the first buffer pad 60 can play a buffering role, effectively avoiding damage to the plate due to excessive clamping force or instantaneous impact force, especially for fragile and easily damaged plates such as glass substrates, which helps to improve the yield and quality of the plate. In addition, the first buffer pad 60 can also increase the friction between the plate and the first clamping surface 11 and absorb the vibration energy during the electroplating process, effectively preventing the plate from sliding or shifting when subjected to external forces.
[0055] Optionally, the first cushioning pad 60 may be, but is not limited to, a sponge pad, a rubber pad, or a foam pad.
[0056] Combined with appendix Figure 1 and Figure 2 It is understandable that the second clamping surface 21 is provided with a second buffer pad 70. During the clamping operation of the plate by the second clamping surface 21 and the first clamping surface 11, the second buffer pad 70 can play a buffering role, effectively avoiding damage to the plate due to excessive clamping force or instantaneous impact force, especially for fragile and easily damaged plates such as glass substrates, which helps to improve the yield and quality of the plate. In addition, the second buffer pad 70 can also increase the friction between the plate and the second clamping surface 21 and absorb the vibration energy during the electroplating process, effectively preventing the plate from sliding or shifting when subjected to external forces.
[0057] Optionally, the second cushioning pad 70 may be, but is not limited to, a sponge pad, a rubber pad, or a foam pad.
[0058] It should be noted that the materials and thicknesses of the first buffer pad 60 and the second buffer pad 70 are determined according to the actual working conditions to ensure that the first buffer pad 60 and the second buffer pad 70 can play a good buffering role on the plate, while keeping the first buffer pad 60 and the second buffer pad 70 within the optimal compression range.
[0059] Optionally, a first insulating layer is provided on the outer surface of the first gripper 10. The first insulating layer may be, but is not limited to, a rubber layer or a plastic layer. When the clamped plate is made of a conductive material or is in a conductive environment, the first insulating layer can effectively isolate the electrical conduction between the first gripper 10 and the plate.
[0060] Optionally, a second insulating layer is provided on the outer surface of the second gripper 20. The second insulating layer may be, but is not limited to, a rubber layer or a plastic layer. When the clamped plate is made of a conductive material or is in a conductive environment, the second insulating layer can effectively isolate the electrical conduction between the second gripper 20 and the plate.
[0061] This application also provides an electroplating apparatus, which includes the clamping mechanism of any of the above embodiments.
[0062] The electroplating equipment provided in this application employs the aforementioned clamping mechanism. When the movable component 40 moves relative to the fixed component 30, the clamping mechanism drives the second gripper 20 to move between the closed and open positions at a preset angle, thereby achieving the action of clamping or releasing the plate. Because the second clamping surface 21 is misaligned with the first clamping surface 11 in the open position, the first clamping surface 11 is completely exposed, forming an unobstructed pick-and-place space on the facing side of the first clamping surface 11. This allows the plate to be placed directly and smoothly on or removed from the first clamping surface 11 through this space, effectively preventing interference between the plate and the second gripper 20 during pick-and-place operations. This significantly improves operational convenience and safety, and is suitable for fragile plates such as glass substrates. In addition, since the preset angle between the second clamping surface 21 and the first clamping surface 11 remains unchanged during the relative movement of the second clamping jaw 20 relative to the first clamping jaw 10, the clamping angle of the first clamping surface 11 and the second clamping surface 21 on the plate does not change when clamping plates of various thicknesses. This allows the first clamping surface 11 and the second clamping surface 21 to make full contact with the opposite sides of the plate, while effectively preventing the glass substrate from deforming or cracking due to local stress concentration.
[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
