[0031] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-4 A clamping device 100 according to an embodiment of the present invention is described. The clamping device 100 includes: a mounting bracket 10 and at least one clamping mechanism 20 .

[0032] Specifically, if Figure 1 、 Figure 2 and Figure 3As shown, the clamping mechanism 20 is connected to the mounting bracket 10 and includes a first clamping member 30 and a second clamping member 40. The first clamping member 30 is provided with a rotatable first clamping jaw 35, and the second clamping member 40 is provided with a retractable second clamping jaw 43. The first clamping jaw 35 and the second clamping jaw 43 have a clamping position in which they are moved toward each other and a release position in which they are moved away from each other. In the clamping position, the first clamping jaw 35 and the second clamping jaw 43 are adapted to abut against the object to be clamped. In this embodiment, the first direction A represents the length of the clamping device 100, the second direction B represents the width of the clamping device 100, and the third direction C represents the height of the clamping device 100. Multiple clamping mechanisms 20 are provided. In this embodiment, the object to be clamped is a PCB.

[0033] Specifically, the mounting bracket 10 extends along a first direction A, and the plurality of clamping mechanisms 20 are spaced apart along the first direction A and connected to the mounting bracket 10. When the clamping device 100 is in operation, the first clamping member 30 rotates toward the second clamping member 40, and the second clamping member 40 moves along a third direction C and toward the first clamping member 35. When the first and second clamping members 35 and 43 reach a clamping position, the PCB is positioned between the first and second clamping members 35 and abuts against the first and second clamping members 35 and 43. Subsequently, the first clamping member 35 rotates away from the second clamping member 40, and the second clamping member 43 moves along the third direction C away from the first clamping member 35. The first and second clamping members 35 and 43 each move to a release position, completing the handling of the PCB. The mounting bracket 10 is adapted to mount and secure the clamping mechanisms 20, which are adapted to clamp the PCB.

[0034] According to the clamping device 100 of the embodiment of the present invention, by moving the first clamping jaw 35 and the second clamping jaw 43 toward and away from each other, the first clamping jaw 35 and the second clamping jaw 43 are moved to the clamping position and the release position to transport the PCB board. This can improve the connection strength between the PCB board and the clamping mechanism 20, prevent the PCB board from falling off during transportation, improve the reliability and stability of the clamping device 100, eliminate the need for manual handling, and improve the degree of automation and work efficiency of the clamping device 100.

[0035] According to some embodiments of the present invention, Figure 2 and Figure 4 As shown, the first clamping member 30 includes: a first shell 31, a first air inlet connector 32 and a first movable component 33. The first air inlet connector 32 is arranged at one end of the first shell 31; the first movable component 33 is movably arranged in the first shell 31, one end of the first movable component 33 is detachably engaged with the first air inlet connector 32, and the other end of the first movable component 33 is rotatably connected to the first clamping claw 35.

[0036] That is, the first shell 31 is extended along the third direction C, the first air inlet connector 32 and the first clamp 35 are respectively arranged at the two ends of the first shell 31 along the third direction C, the first movable component 33 is arranged between the first air inlet connector 32 and the first clamp 35, one end of the first movable component 33 adjacent to the first air inlet connector 32 is separably matched with the first air inlet connector 32 along the third direction C, and the other end of the first movable component 33 adjacent to the first clamp 35 is rotatably connected to the first clamp 35. In this embodiment, the end of the first air inlet connector 32 away from the first movable component 33 is connected to a positive pressure air source.

[0037] Therefore, one end of the first movable component 33 is detachably engaged with the first air inlet connector 32, and the other end of the first movable component 33 is rotatably connected to the first clamping jaw 35. After the first air inlet connector 32 is connected to the positive pressure air source, the first movable component 33 is driven to move toward the first clamping jaw 35 to drive the first clamping jaw 35 to rotate, thereby improving the flexibility and working efficiency of the clamping device 100.

[0038] According to some embodiments of the present invention, Figure 4 As shown, the first movable component 33 includes: a slider 331 and a connecting rod 332, the slider 331 is movably arranged in the first shell 31; one end of the connecting rod 332 is rotatably connected to the slider 331, and the other end of the connecting rod 332 is rotatably and movably connected to the first clamp 35.

[0039] That is, the slider 331 is arranged at one end of the first air inlet connector 32 adjacent to the first clamp 35, and the slider 331 can be separably matched with the first air inlet connector 32 along the third direction C. The connecting rod 332 is rotatably connected to the slider 331 at one end adjacent to the slider 331, and extends obliquely toward the first clamp 35 along the third direction C. The other end of the connecting rod 332 adjacent to the first clamp 35 is rotatably and movably connected to the first clamp 35.

[0040] Thus, the slider 331 can be movably arranged in the first shell 31, and one end of the connecting rod 332 is rotatably connected to the slider 331, and the other end of the connecting rod 332 is rotatably and movably connected to the first clamping jaw 35. After the first air inlet connector 32 is connected to the positive pressure air source, the slider 331 is driven to move toward the first clamping jaw 35, so that the end of the connecting rod 332 connected to the slider 331 rotates clockwise, and the other end of the connecting rod 332 adjacent to the first clamping jaw 35 rotates counterclockwise and moves along the third direction C toward and away from the first air inlet connector 32, so that the first clamping jaw 35 rotates toward the second clamping jaw 43 until it reaches the clamping position.

[0041] According to some embodiments of the present invention, Figure 4 As shown, a mounting groove 333 is formed at one end of the slider 331 adjacent to the connecting rod 332 , and one end of the connecting rod 332 is disposed in the mounting groove 333 .

[0042] That is, a mounting groove 333 is formed at one end of the slider 331 away from the first air inlet connector 32 along the third direction C, and the end of the connecting rod 332 adjacent to the slider 331 is arranged in the mounting groove 333 and is rotatably connected to the slider 331. The mounting groove 333 is suitable for installing the end of the connecting rod 332 adjacent to the slider 331.

[0043] Therefore, by forming a mounting groove 333 at one end of the slider 331 adjacent to the connecting rod 332, the height of the end of the connecting rod 332 adjacent to the slider 331 along the third direction C can be lowered, and the rotation angle of the end of the connecting rod 332 adjacent to the slider 331 and the other end of the connecting rod 332 adjacent to the first clamp 35 can be increased, thereby improving the working efficiency and reliability of the clamping device 100.

[0044] According to some embodiments of the present invention, Figure 2 and Figure 4 As shown, the first clamping member 30 further includes: a clamping claw joint 34, which is provided at the other end of the first shell 31 away from the first air inlet joint 32, and the first clamping claw 35 is rotatably connected to the clamping claw joint 34.

[0045] That is, the clamp joint 34 is arranged at the other end of the first shell 31 away from the first air inlet joint 32 along the third direction C, and the end of the first clamp 35 adjacent to the connecting rod 332 is rotatably connected to the clamp joint 34, and the other end of the first clamp 35 away from the connecting rod 332 can move toward or away from the second clamp 43, wherein the clamp joint 34 is suitable for fixing the ends of the connecting rod 332 and the first clamp 35 adjacent to each other.

[0046] Therefore, the clamp joint 34 is arranged at the other end of the first shell 31 away from the first air inlet joint 32, and the first clamp 35 is rotatably connected to the clamp joint 34, which can facilitate the installation of the first clamp 35 on the first shell 31, improve the reliability of the connection between the first clamp 35 and the first shell 31, and at the same time shorten the distance between the first clamp 35 and the first air inlet joint 32 along the third direction C, thereby shortening the response time of the rotation of the first clamp 35 and improving the working efficiency of the clamping device 100.

[0047] According to some embodiments of the present invention, Figure 4 As shown, the first movable assembly 33 includes: a limiting member 334 , which is provided between the slider 331 and the clamping jaw joint 34 , and is connected to either the slider 331 or the clamping jaw joint 34 .

[0048] For example, the limit member 334 is arranged along the third direction C at one end of the slider 331 away from the first air inlet connector 32, and forms a fixed connection with the slider 331. After the first air inlet connector 32 is connected to the positive pressure air source, the slider 331 and the limit member 334 are driven to move toward the first clamp 35 together. The limit member 334 can move along the third direction C until it stops at the clamp connector 34.

[0049] Optionally, the limiting member 334 may be provided at one end of the clamping jaw joint 34 adjacent to the slider 331 along the third direction C, and be fixedly connected to the clamping jaw joint 34 .

[0050] Therefore, by arranging the limit member 334 between the slider 331 and the clamping joint 34, and the limit member 334 is connected to either the slider 331 or the clamping joint 34, when the slider 331 moves toward the clamping joint 34 to a certain extent along the third direction C, it can stop moving, thereby preventing the connecting rod 332 from rotating too much and colliding with the inner wall of the first shell 31, and at the same time preventing the slider 331 from colliding with the clamping joint 34 and the first clamping jaw 35 from colliding with the PCB board, thereby extending the service life of the clamping mechanism 20 and improving the stability of the operation of the clamping device 100.

[0051] According to some embodiments of the present invention, Figure 4 As shown, the first movable assembly 33 further includes an elastic member 335 , which is disposed between the slider 331 and the clamping jaw joint 34 , and the elastic member 335 abuts against the slider 331 and the clamping jaw joint 34 respectively.

[0052] That is, the elastic member 335 is disposed between the slider 331 and the clamping joint 34 along the third direction C, and the elastic member 335 is in contact with the inner circumferential wall of the first housing 31. The two ends of the elastic member 335 along the third direction C abut against the slider 331 and the clamping joint 34, respectively, and the elastic member 335 can be telescopically engaged with the slider 331 and the clamping joint 34 along the third direction C. In this embodiment, the elastic member 335 can be a spring.

[0053] When the first air inlet connector 32 is connected to the positive pressure air source, the slider 331 is driven to move along the third direction C toward the clamping jaw connector 34, causing the elastic member 335 to be compressed. At the same time, the end of the connecting rod 332 connected to the slider 331 rotates clockwise, and the other end of the connecting rod 332 adjacent to the first clamping jaw 35 rotates counterclockwise, causing the first clamping jaw 35 to rotate toward the second clamping jaw 43 and stop at the PCB board; when the slider 331 is not subjected to the pressure of the positive pressure air source, the elastic member 335 is reset, causing the slider 331 to move along the third direction C toward the first air inlet connector 32, the end of the connecting rod 332 connected to the slider 331 rotates counterclockwise, and the other end of the connecting rod 332 adjacent to the first clamping jaw 35 rotates clockwise, causing the first clamping jaw 35 to rotate in a direction away from the second clamping jaw 43.

[0054] Therefore, by arranging an elastic member 335 between the slider 331 and the clamping jaw joint 34, the movement of the slider 331 along the third direction C can be buffered to avoid the slider 331 from colliding with the first air inlet joint 32. Through the compression and resetting of the spring member, the slider 331 can be moved toward the first air inlet joint 32 when the slider 331 is not subjected to the pressure of the positive pressure air source without manual operation, thereby effectively improving the reliability of the clamping device 100, reducing the degree of automation and stability of the clamping device 100, and reducing labor costs.

[0055] According to some embodiments of the present invention, at least one of the first air inlet connector 32 and the clamping connector 34 is detachably connected to the first housing 31 .

[0056] For example, the first air inlet connector 32 is detachably connected to the first shell 31. By disassembling and installing the first air inlet connector 32, the first movable component 33 can be arranged inside the first shell 31 along the third direction C from one end of the first shell 31 away from the clamping joint 34.

[0057] Optionally, the clamp joint 34 can be detachably connected to the first shell 31. By removing and installing the clamp joint 34, the first movable component 33 can be arranged inside the first shell 31 along the third direction C from one end of the first shell 31 away from the first air inlet joint 32.

[0058] Thus, at least one of the first air inlet connector 32 and the clamping jaw connector 34 is detachably connected to the first shell 31, which can facilitate the installation of the first movable component 33 into the inside of the first shell 31, thereby improving the assembly efficiency of the clamping device 100. At the same time, it facilitates the maintenance and replacement of the first movable component 33 inside the first shell 31, thereby improving the convenience and practicality of using the clamping device 100.

[0059] According to some embodiments of the present invention, Figure 4 As shown, the first clamping jaw 35 includes: a first connecting end 351, a second connecting end 352 and a clamping end 353. The first connecting end 351 is rotatably connected to the other end of the connecting rod 332; the second connecting end 352 is rotatably connected to the clamping jaw joint 34; the clamping end 353 is arranged on the side of the second connecting end 352 away from the first connecting end 351; the structure formed by the first connecting end 351, the second connecting end 352 and the clamping end 353 being connected to each other is a polygonal structure.

[0060] In this embodiment, the other end of the connecting rod 332 away from the slider 331 can be rotatably connected to the first connecting end 351 of the first clamping jaw 35 adjacent to the connecting rod 332 by a pin; the clamping end 353 is the end of the first clamping jaw 35 away from the first connecting end 351, and the clamping end 353 is suitable for abutting against the lower end surface of the PCB board; a second connecting end 352 is provided between the clamping end 353 and the first connecting end 351, and the second connecting end 352 and the clamping jaw joint 34 can be rotatably connected by a pin.

[0061] When the other end of the connecting rod 332 adjacent to the first clamping jaw 35 rotates counterclockwise, the first connecting end 351 and the second connecting end 352 rotate clockwise, thereby driving the clamping end 353 to rotate clockwise toward the second clamping jaw 43 to stop against the PCB board; when the other end of the connecting rod 332 adjacent to the first clamping jaw 35 rotates clockwise, the first connecting end 351 and the second connecting end 352 rotate counterclockwise, thereby driving the clamping end 353 to rotate counterclockwise toward the direction away from the second clamping jaw 43 to separate from the PCB board.

[0062] Thus, the first connecting end 351 is rotatably connected to the other end of the connecting rod 332, and the second connecting end 352 is rotatably connected to the clamping jaw joint 34. The volume of the first clamping jaw 35 is relatively small, so that the rotation angle of the first clamping jaw 35 is increased, thereby improving the working efficiency of the first clamping jaw 35. At the same time, the structure formed by the first connecting end 351, the second connecting end 352 and the clamping end 353 being connected to each other is a polygonal structure, which can improve the stability of the first clamping jaw 35, thereby improving the stability and reliability of the clamping device 100.

[0063] According to some embodiments of the present invention, Figure 4 As shown, the clamping device 100 further includes a sealing member 50 , which is disposed between the slider 331 and the first housing 31 .

[0064] Specifically, the seal 50 is disposed on the inner circumference of the slider 331 and the first housing 31. The seal 50 is in close contact with the inner circumference of the first housing 31. The seal 50 is adapted to prevent the positive pressure air source and other impurities from entering between the slider 331 and the jaw joint 34 through the gap between the slider 331 and the first housing 31. In this embodiment, the seal 50 may be a sealing ring.

[0065] Therefore, by setting a seal 50 on the inner circumference of the slider 331 and the first shell 31, the sealing between the slider 331 and the clamping jaw joint 34 can be effectively improved, and the positive pressure air source can be prevented from entering between the slider 331 and the clamping jaw joint 34 to affect the movement of the first movable component 33 and the first clamping jaw 35, thereby ensuring the normal operation of the clamping device 100 and improving the overall sealing and reliability of the clamping device 100.

[0066] According to some embodiments of the present invention, Figure 2 and Figure 3 As shown, the second clamping member 40 includes: a second shell 41 and a second air inlet connector 42, the second air inlet connector 42 is arranged at one end of the second shell 41, and the second clamping jaw 43 is arranged at the other end of the second shell 41 away from the second air inlet connector 42, and the second clamping jaw 43 can move toward and away from the first clamping jaw 35 telescopically relative to the second shell 41.

[0067] Specifically, the second housing 41 extends along the third direction C and is spaced apart along the second direction B between the mounting bracket 10 and the first housing 31. The second air inlet connector 42 is disposed at one end of the second housing 41 adjacent to the first air inlet connector 32 along the third direction C. The second clamping jaw 43 is disposed at the other end of the second housing 41 adjacent to the first clamping jaw 35 along the third direction C. When the second air inlet connector 42 is connected to a positive pressure air source, the second clamping jaw 43 is driven to move along the third direction C toward the first clamping jaw 35 until it abuts against the upper end surface of the PCB. When the second air inlet connector 42 is disconnected from the positive pressure air source, the second clamping jaw 43 is allowed to move along the third direction C away from the first clamping jaw 35.

[0068] Therefore, by setting up the second clamping member 40, the second clamping jaw 43 can move telescopically toward and away from the first clamping jaw 35 relative to the second shell 41, and cooperate with the first clamping jaw 35 to clamp and release the PCB board to realize the transportation of the PCB board. It can press the PCB board to prevent the PCB board from falling off during transportation, and effectively improve the stability and reliability of the clamping device 100.

[0069] According to some embodiments of the present invention, Figure 2 As shown, the clamping device 100 further includes: a connecting plate 51 , the connecting plate 51 is connected to the mounting bracket 10 , and the first clamping member 30 and the second clamping member 40 are provided on the connecting plate 51 .

[0070] That is, the connecting plate 51 extends along the second direction B, and is connected to the mounting bracket 10 at one end of the connecting plate 51 adjacent to the mounting bracket 10 along the second direction B. The first clamping member 30 and the second clamping member 40 are spaced apart and arranged at the other end of the connecting plate 51 away from the mounting bracket 10 along the second direction B. The connecting plate 51 includes a first surface and a second surface, the first surface being located above the second surface along the third direction C. The first air inlet connector 32 of the first clamping member 30, the first movable assembly 33, and the second air inlet connector 42 of the second clamping member 40 are located on the first surface of the connecting plate 51 along the third direction C. The first clamping jaw 35 of the first clamping member 30 and the second clamping jaw 43 of the second clamping member 40 are located on the second surface of the connecting plate 51 along the third direction C.

[0071] Therefore, by setting up the connecting plate 51, the connecting plate 51 is connected to the mounting bracket 10, and the first clamping member 30 and the second clamping member 40 are arranged on the connecting plate 51, which can facilitate the first clamping member 30 and the second clamping member 40 to be fixed to the mounting bracket 10, improve the connection strength between the first clamping member 30 and the second clamping member 40 and the mounting bracket 10, and at the same time improve the installation efficiency of the first clamping member 30 and the second clamping member 40, thereby improving the overall structural strength, reliability and stability of the clamping device 100.
