Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor manufacturing, and in particular to a clamping device for fixing a control board. Background Art

[0002] During the production and repair of semiconductor bonding equipment and automotive electronic control boards (such as reducer control boards, ECUs, etc.), it is usually necessary to accurately position and stably clamp the circuit boards to ensure the reliability of processes such as bonding, welding, or testing.

[0003] However, the traditional solution takes too long to clamp the control board during production and repair, which affects efficiency.

[0004] BACKGROUND OF THE INVENTION The above information disclosed is only for understanding the background of the concept of the application and may contain information that does not constitute the prior art. Summary of the Invention

[0005] Based on this, it is necessary to provide a clamping device for fixing the control panel to address the above problems.

[0006] A clamping device for fixing a control panel, comprising:

[0007] base;

[0008] a guide column, the guide column being provided on the base and used for supporting the control panel;

[0009] an elastic component, the elastic component being sleeved on the guide post and being capable of sliding along the guide post;

[0010] a clamping assembly, the clamping assembly being disposed on the base and connected to the elastic assembly; and

[0011] A driving assembly is provided on the base and can move relative to the base to a first position and a second position. When in the first position, the clamping assembly can have a movement tendency toward the direction close to the guide column under the elastic force of the elastic assembly to clamp the control board; when in the second position, the driving assembly can abut against at least part of the elastic assembly and overcome the elastic force of the elastic assembly, so that the clamping assembly moves toward the direction away from the guide column to open.

[0012] The clamping device for fixing the control panel described above can achieve at least the following beneficial effects: The clamping device for fixing the control panel of the present invention, through its innovative mechanical structure and elastic component design, achieves an efficient, stable, and highly adaptable clamping function. The device is primarily composed of a base, a guide post, an elastic component, a clamping component, and a drive component. The guide post is fixed to the base to support the control panel, the elastic component is mounted on the guide post and can slide along the guide post, the clamping component is connected to the elastic component, and the drive component controls the clamping state by switching between a first position and a second position. First, the clamping device is convenient and efficient to operate. The simple movement of the drive component allows for rapid clamping and loosening, significantly reducing operation time compared to traditional methods of fixing the control panel, such as screws. Second, the design of the elastic component enables the clamping force to adapt to control panels of varying thicknesses, ensuring secure clamping while avoiding damage due to overpressure. The coordination of the guide post and the elastic component ensures high-precision positioning during the clamping process, meeting the requirements of precision manufacturing.

[0013] In some embodiments, the elastic assembly includes an elastic member and a connecting plate disposed on the outer circumference of the guide post. The connecting plate is capable of sliding along the length of the guide post. Under the elastic force of the elastic member, the connecting plate has a tendency to slide downward along the axial direction of the guide post toward the base, thereby driving the clamping assembly toward the guide post. Under the drive assembly, the connecting plate is also capable of overcoming the elastic force of the elastic member, causing the clamping assembly to move away from the guide post to expand. The connecting plate is disposed on the outer circumference of the guide post and is capable of sliding along the length of the guide post, ensuring a stable motion trajectory and preventing deflection. In its natural state, the connecting plate, under the elastic force of the elastic member, has a tendency to slide downward along the axial direction of the guide post, thereby driving the clamping assembly toward the guide post, thereby achieving stable clamping of the control panel. The elastic member provides the necessary elastic restoring force, allowing the connecting plate to automatically reset when no external force is applied, ensuring that the clamping assembly maintains a clamping tendency. When the drive assembly is activated, it overcomes the elastic force of the spring member, causing the connecting plate to move upward, driving the clamping assembly away from the guide post and opening, facilitating quick access to the control panel. It should be noted that springs with varying stiffness or pre-compression can be selected to achieve adaptive adjustment based on the thickness of the control panel and the required clamping force. This structural design ensures stable and reliable clamping and can accommodate control panels of varying thicknesses.

[0014] In some embodiments, the elastic member is a compression spring, and the clamping device further includes a limit member provided on the top of the guide column, the limit member can be used to support the control board, and the elastic member is provided on the side of the connecting plate facing away from the base and elastically abuts between the limit member and the connecting plate. The clamping device also provides a limit member on the top of the guide column for supporting the control board. The compression spring is installed on the side of the connecting plate facing away from the base and elastically abuts between the limit member and the connecting plate. This arrangement keeps the compression spring in a compressed state at all times, providing a stable downward pressure for the connecting plate and ensuring that the clamping assembly maintains a clamping tendency. When the driving assembly acts, the elastic force of the compression spring can be overcome to move the connecting plate upward, thereby realizing the opening action of the clamping assembly. The setting of the limit member not only supports the control board, but also provides a reliable abutting position for the compression spring.

[0015] In some embodiments, the elastic member is a tension spring, which is disposed between the connecting plate and the base. The tension spring is disposed between the connecting plate and the base and is always in a stretched state. When the drive assembly is not in operation, the tension of the tension spring causes the connecting plate to slide downward, driving the clamping assembly toward the guide post to achieve clamping. When the drive assembly is activated, the tension of the tension spring is overcome to cause the connecting plate to move upward, driving the clamping assembly away from the guide post to achieve opening. This tension spring arrangement is compact and particularly suitable for applications requiring a large clamping stroke.

[0016] In some embodiments, the elastic assembly further comprises a linear bearing, through which the connecting plate is slidably mounted on the outer circumference of the guide post. The outer ring of the linear bearing is fixed to the connecting plate, which is slidably mounted on the outer circumference of the guide post. One end of the elastic member is connected to the linear bearing, and the other end of the elastic member is connected to the base or the stopper. The connecting plate is slidably mounted on the outer circumference of the guide post via the linear bearing. The outer ring of the linear bearing is fixed to the connecting plate, and the inner ring cooperates with the guide post to ensure smooth axial sliding of the connecting plate along the guide post, reducing frictional resistance. The linear bearing optimizes motion accuracy, while the flexible arrangement of the elastic member accommodates different clamping requirements, resulting in a device with both high reliability and long life. One end of the elastic member (such as a compression spring or a tension spring) is connected to the linear bearing, and the other end is selected based on the specific embodiment: if a compression spring is used, the other end abuts the stopper, causing the spring to be compressed and provide a downward clamping force; if a tension spring is used, the other end is fixed to the base, causing the spring to be stretched and provide an upward return force.

[0017] In some embodiments, the clamping assembly includes two clamping arms and two support posts. Both support posts are mounted on the base and located on either side of the connecting plate. The middle portion of one clamping arm is pivotally connected to one support post, while the middle portion of the other clamping arm is pivotally connected to the other support post. Each clamping arm has a clamping end and a linkage end that are spaced apart from each other. The linkage ends of the two clamping arms are connected to either side of the connecting plate and are driven by the connecting plate to rotate the two clamping arms around the two support posts, respectively, so that the clamping ends of the two clamping arms move closer to or further away from the guide post. The two support posts are fixedly mounted on the base and located on either side of the connecting plate. The middle portion of each clamping arm is pivotally connected to a corresponding support post, enabling the clamping arm to rotate around the support post. Each clamping arm has two functional ends: a clamping end and a linkage end, located on opposite sides of the pivotal connection point. The linkage ends of the two clamping arms are connected to either side of the connecting plate, while the clamping ends extend toward the guide post. When the connecting plate moves up and down under the influence of a drive mechanism or elastic component, it drives the linked ends of the two clamping arms to move synchronously, causing them to rotate in opposite directions around their respective support columns. This rotation causes the clamping ends of the two clamping arms to move toward or away from each other, tightening or loosening the workpiece. This structure, which converts the linear motion of the connecting plate into the opening and closing motion of the clamping ends through the principle of leverage, offers simple construction and reliable operation.

[0018] In some embodiments, each of the linkage ends is provided with a sliding protrusion, and the connecting plate is provided with a limiting slide groove that is compatible with the sliding protrusion in number and shape. The two sliding protrusions are respectively slidably arranged in the two limiting slide grooves on both sides of the connecting plate. When the connecting plate slides axially along the guide column, each of the sliding protrusions can slide in the limiting slide groove under the abutment of the groove wall of the limiting slide groove and drive the clamping arm to rotate around the support column, so that the clamping end of the clamping arm approaches or moves away from the guide column. The clamping assembly's linkage mechanism utilizes a combination of sliding protrusions and limiting grooves. Each clamping arm's linkage end is equipped with a sliding protrusion, while matching limiting grooves are symmetrically located on either side of the connecting plate. As the connecting plate slides axially along the guide column, the walls of the limiting grooves abut and push against the sliding protrusions, forcing the linkage end to displace. Due to the pivotal connection between the middle portion of the clamping arm and the support column, this displacement is converted into a lever-like rotation of the clamping arm, driving the clamping ends toward or away from each other, thereby clamping or releasing the workpiece. This structure transmits power through rigid contact, ensuring synchronous and reliable movement while reducing friction, making the overall mechanism smoother and suitable for clamping in space-constrained environments. Each clamping arm's linkage end is equipped with a sliding protrusion (such as a bump, pin, or roller) in a cylindrical, rectangular, or other compatible groove configuration. The limiting grooves are symmetrically located on either side of the connecting plate, matching the number and shape of the sliding protrusions and typically taking the form of linear, curved, or oblique channels. As the connecting plate slides axially (up and down) along the guide post, the walls of the limiting slot abut and push against the sliding protrusion, forcing the linkage end to follow. Because the middle portion of the clamping arm is pivotally connected to the support post, the displacement of the sliding protrusion translates into a lever-like rotation of the clamping arm around the support post, driving the clamping end toward or away from the guide post.

[0019] In some embodiments, the two clamping arms are symmetrically disposed on either side of the connecting plate and are capable of opening or closing during movement relative to the guide post. The two clamping arms are symmetrically disposed on either side of the connecting plate. When the connecting plate moves axially along the guide post, the linkage ends of the clamping arms, through the cooperation of sliding protrusions and limiting slots, cause the two clamping arms to rotate synchronously about the support post, thereby achieving synchronized opening or closing during movement relative to the guide post, thereby ensuring stability and precision in the clamping action.

[0020] In some embodiments, the clamping assembly further includes a pressure head, one of which is connected to each clamping end and configured to abut against the control panel when in proximity to the guide post. The pressure head may be made of a flexible material. When the clamping arm is closed, the pressure head moves with the clamping end and abuts against the surface of the control panel. The flexible material of the pressure head provides stable contact pressure while preventing surface damage caused by rigid contact, making it suitable for clamping precision workpieces.

[0021] In some embodiments, the clamping assembly further includes a rolling member, which is rotatably connected to the side of the connecting plate facing the base, and the driving assembly includes a wedge member and a driving member, the driving member is provided on the base and connected to the wedge member, and the side of the wedge member facing the rolling member is provided with a guide slope, and the wedge member can approach or move away from the rolling member under the drive of the driving member; when the wedge member approaches the rolling member, the rolling member can overcome the elastic force of the elastic member under the abutment of the guide slope and roll upward along the guide slope and at the same time drive the connecting plate to rise until the wedge member moves to the second position; when the wedge member moves away from the rolling member, the rolling member can roll downward along the guide slope under the action of the elastic force of the elastic member and drive the connecting plate to descend until the wedge member moves to the first position. When the driver pushes the wedge toward the rolling element, the rolling element, abutted by the guide slope, overcomes the elastic force of the elastic element and rolls upward along the slope, thereby driving the connecting plate upward until the wedge reaches the second position (clamping arm closed state). Conversely, when the driver drives the wedge away from the rolling element, the restoring force of the elastic element causes the rolling element to roll downward along the slope, and the connecting plate descends accordingly until the wedge returns to the first position (clamping arm open state). This structure achieves stable and controllable clamping action through the mechanical force amplification of the wedge slope.

[0022] In some embodiments, the driving member is a toggle clamp.

[0023] In some embodiments, the drive assembly further includes a fixed seat provided on the base, the drive member can be movably passed through the fixed seat, one end of the drive member is connected to the wedge member, and the other end of the drive member is used for operation to drive the movement of the wedge member. The drive assembly further includes a fixed seat fixedly mounted on the base, the drive member can be slidably passed through the fixed seat, one end of which is connected to the wedge member, and the other end extends to the outside for the operator to apply force or connect to a power source (such as a cylinder, motor, etc.). By pushing and pulling the drive member, the wedge member can be driven to move along the guide of the fixed seat, thereby accurately controlling the lifting and lowering of the rolling member and the opening and closing of the clamping assembly. This structure enhances the driving stability and facilitates manual or automatic operation.

[0024] In some embodiments, the driving member is a motor and is capable of driving the wedge-shaped member to perform telescopic motion to move closer to or away from the rolling member. The driving member uses a motor (such as a servo motor, a stepper motor, or a linear motor) and drives the wedge-shaped member to perform linear reciprocating motion through a transmission mechanism (such as a screw, a gear rack, or a connecting rod) to move it closer to or away from the rolling member. The rotational motion of the motor is converted into the telescopic motion of the wedge-shaped member, thereby accurately controlling the lifting and lowering of the rolling member and the opening and closing state of the clamping arm. This design can realize automated control, improve the accuracy and response speed of the clamping action, and is suitable for scenarios requiring high-frequency or programmed operations.

[0025] In some embodiments, the clamping device further includes a limiting column, which is provided on the base and is used to abut against the edge of the control panel to achieve the limitation and positioning of the control panel. The clamping device further includes a limiting column fixed to the base, which can be vertically arranged and abut against the side edge of the control panel. When the control panel is raised and lowered with the rolling element, the limiting column constrains the horizontal displacement of the control panel through physical contact, ensuring that it moves precisely within the preset path to avoid deflection or shaking. This structure is simple and reliable, which not only realizes the guiding and positioning of the control panel, but also enhances the stability during the clamping process. It is particularly suitable for assembly or processing scenarios with high requirements for position accuracy.

[0026] In some embodiments, the clamping device further includes a positioning column, which is provided on the base and is used to be inserted into the positioning hole on the control board to achieve the limitation and positioning of the control board. The clamping device also includes a positioning column fixed to the base, which can be vertically arranged and matched with the positioning hole on the control board. When the control board moves with the rolling element, the positioning column is inserted into the positioning hole to form a plug-in limiting structure, which effectively constrains the horizontal freedom of the control board and ensures its precise movement along the preset trajectory. This design achieves dual positioning (vertical limitation + horizontal anti-deflection) through mechanical coordination, significantly improving the repeatability and anti-interference ability of the control board, and is particularly suitable for high-precision assembly or automated production lines that require frequent reset.

[0034] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In some embodiments, the present application provides a clamping device 10 for fixing a control board 20, which includes a base 100, a guide column 200, an elastic component 300, a clamping component 400, and a driving component 500. The guide column 200 is provided on the base 100 and is used to support the control board 20; the elastic component 300 is sleeved on the guide column 200 and can slide along the guide column 200; the clamping component 400 is provided on the base 100 and connected to the elastic component 300; the driving component 500 is provided on the base 100 and can move to a first position and a second position relative to the base 100. Figure 3 and Figure 4As shown, in the first position, the clamping assembly 400 can have a movement tendency toward the direction close to the guide column 200 under the elastic force of the elastic assembly 300 to clamp the control board 20; in the second position, the driving assembly 500 can abut against at least part of the elastic assembly 300 and overcome the elastic force of the elastic assembly 300, so that the clamping assembly 400 moves toward the direction away from the guide column 200 to open.

[0036] The clamping device 10 for fixing the control panel 20 can at least achieve the following beneficial effects: The clamping device 10 for fixing the control panel 20 of the present invention realizes an efficient, stable and adaptable clamping function through an innovative mechanical structure and elastic component 300 design. The device is mainly composed of a base 100, a guide column 200, an elastic component 300, a clamping component 400 and a drive component 500. Among them, the guide column 200 is fixed on the base 100 for supporting the control panel 20, the elastic component 300 is mounted on the guide column 200 and can slide along it, the clamping component 400 is connected to the elastic component 300, and the drive component 500 controls the clamping state by switching between a first position and a second position. Firstly, the clamping device 10 is easy and efficient to operate. The simple action of the drive component 500 can achieve quick clamping and loosening, which greatly shortens the operation time compared to traditional methods such as screws to fix the control panel 20. Secondly, the design of the elastic component 300 enables the clamping force to adapt to the thickness of the control board 20, ensuring a secure clamping force while avoiding damage due to overpressure. The cooperation between the guide column 200 and the elastic component 300 ensures high-precision positioning during the clamping process, meeting the requirements of precision manufacturing.

[0037] like Figure 3 and Figure 4As shown, in some embodiments, the elastic assembly 300 includes an elastic member 310 and a connecting plate 320 sleeved on the outer circumference of the guide post 200. The connecting plate 320 is capable of sliding along the length extension direction of the guide post 200. Under the elastic force of the elastic member 310, the connecting plate 320 has a tendency to slide downward along the axial direction of the guide post 200 toward the base 100, thereby driving the clamping assembly 400 toward the guide post 200. The connecting plate 320 can also overcome the elastic force of the elastic member 310 under the drive of the drive assembly 500, causing the clamping assembly 400 to move away from the guide post 200 to open. The connecting plate 320 is sleeved on the outer circumference of the guide post 200 and is capable of sliding along the length extension direction of the guide post 200, ensuring a stable motion trajectory and preventing deflection. In its natural state, the connecting plate 320 is subjected to the elastic force of the elastic member 310 and has a tendency to slide downward along the axial direction of the guide column 200, thereby driving the clamping assembly 400 to move toward the guide column 200, thereby achieving stable clamping of the control panel 20. The elastic member 310 provides the necessary elastic restoring force, so that the connecting plate 320 automatically resets when no external force is applied, ensuring that the clamping assembly 400 always has a clamping tendency. When the drive assembly 500 is actuated, it can overcome the elastic force of the elastic member 310 to move the connecting plate 320 upward, driving the clamping assembly 400 to move away from the guide column 200 to open, facilitating the rapid removal and placement of the control panel 20. It should be noted that springs of different stiffness or pre-compression can be selected according to the thickness and clamping force requirements of different control panels 20 to achieve adaptive adjustment. This structural design makes the clamping action stable and reliable, and can adapt to the clamping requirements of control panels 20 of different thicknesses.

[0038] like Figure 3 As shown, in some embodiments, the elastic member 310 is a compression spring. The clamping device 10 also includes a stopper 210 disposed on the top of the guide post 200. The stopper 210 is capable of supporting the control board 20. The elastic member 310 is disposed on the side of the connecting plate 320 facing away from the base 100 and elastically abuts between the stopper 210 and the connecting plate 320. The clamping device 10 also includes a stopper 210 disposed on the top of the guide post 200 to support the control board 20. The compression spring is mounted on the side of the connecting plate 320 facing away from the base 100 and elastically abuts between the stopper 210 and the connecting plate 320. This arrangement keeps the compression spring in a constant compressed state, providing a stable downward force on the connecting plate 320 and ensuring that the clamping assembly 400 maintains a clamping tendency. When the drive assembly 500 is activated, the elastic force of the compression spring is overcome, causing the connecting plate 320 to move upward, thereby opening the clamping assembly 400. The setting of the limiting member 210 not only supports the control board 20, but also provides a reliable supporting position for the compression spring.

[0039] In some embodiments, the elastic member 310 is a tension spring, and the elastic member 310 is arranged between the connecting plate 320 and the base 100. The tension spring is arranged between the connecting plate 320 and the base 100 and is always in a stretched state. When the driving assembly 500 is not in effect, the tension of the tension spring causes the connecting plate 320 to have a tendency to slide downward, driving the clamping assembly 400 to move toward the guide column 200 to achieve clamping. When the driving assembly 500 is in effect, the tension of the tension spring can be overcome to move the connecting plate 320 upward, driving the clamping assembly 400 away from the guide column 200 to achieve opening. This tension spring arrangement has a compact structure and is particularly suitable for occasions requiring a larger clamping stroke.

[0040] like Figure 3 As shown, in some embodiments, the elastic assembly 300 further includes a linear bearing 330, through which the connecting plate 320 is slidably mounted on the outer circumference of the guide column 200. The outer ring of the linear bearing 330 is fixed to the connecting plate 320. The linear bearing is slidably mounted on the outer circumference of the guide column 200. One end of the elastic member 310 is connected to the linear bearing 330, and the other end of the elastic member 310 is connected to the base 100 or the stopper 210. The connecting plate 320 is slidably mounted on the outer circumference of the guide column 200 through the linear bearing 330. The outer ring of the linear bearing 330 is fixed to the connecting plate 320, and the inner ring cooperates with the guide column 200 to ensure that the connecting plate 320 slides smoothly along the axial direction of the guide column 200, reducing frictional resistance. The linear bearing 330 optimizes motion accuracy, while the flexible arrangement of the elastic member 310 adapts to different clamping requirements, making the device both highly reliable and long-lasting. One end of the elastic member 310 (such as a compression spring or a tension spring) is connected to the linear bearing 330, and the other end is selected according to the specific implementation method: if a compression spring is used, the other end is abutted against the limit member 210, so that the spring is in a compressed state, providing a downward clamping force; if a tension spring is used, the other end is fixed to the base 100, so that the spring is in a stretched state, providing an upward reset force.

[0041] like Figure 3As shown, in some embodiments, the clamping assembly 400 includes two clamping arms 410 and two support columns 420. The two support columns 420 are both provided on the base 100 and are respectively located on both sides of the connecting plate 320. The middle portion of one clamping arm 410 is rotatably connected to one support column 420, and the middle portion of the other clamping arm 410 is rotatably connected to the other support column. Each clamping arm 410 has a clamping end 411 and a linkage end 412 that are separated from each other. The linkage ends 412 of the two clamping arms 410 are respectively connected to both sides of the connecting plate 320 and can be driven by the connecting plate 320 to cause the two clamping arms 410 to rotate around the two support columns 420 respectively, so that the clamping ends 411 of the two clamping arms 410 are close to or away from the guide column 200. The two support columns 420 are fixedly mounted on the base 100 and are respectively located on both sides of the connecting plate 320. The middle portion of each clamping arm 410 is mounted on the corresponding support column 420 via a pivoting connection, allowing the clamping arm 410 to rotate about the support column 420. Each clamping arm 410 has two functional ends: a clamping end 411 and a linkage end 412, located on opposite sides of the pivoting connection point. The linkage ends 412 of the two clamping arms 410 are respectively connected to opposite sides of the connecting plate 320, while the clamping ends 411 extend toward the guide column 200. When the connecting plate 320 moves up and down under the action of the drive mechanism or elastic component 300, it drives the linkage ends 412 of the two clamping arms 410 to move synchronously, causing the two clamping arms 410 to rotate in opposite directions about their respective support columns 420. This rotation causes the clamping ends 411 of the two clamping arms 410 to move toward or away from each other, thereby clamping or releasing the workpiece. This structure converts the linear motion of the connecting plate 320 into the opening and closing motion of the clamping end 411 through the lever principle, and has the characteristics of simple structure and reliable operation.

[0042] like Figure 3As shown, in some embodiments, each of the linkage ends 412 is provided with a sliding protrusion 413, and the connecting plate 320 is provided with a limiting slide 321 that is adapted to the sliding protrusion 413 in number and shape. The two sliding protrusions 413 are respectively slidably arranged in the two limiting slides 321 on both sides of the connecting plate 320. When the connecting plate 320 slides axially along the guide column 200, each of the sliding protrusions can slide in the limiting slide 321 under the abutment of the groove wall of the limiting slide 321 and drive the clamping arm 410 to rotate around the support column 420, so that the clamping end 411 of the clamping arm 410 approaches or moves away from the guide column 200. The linkage mechanism of the clamping assembly 400 adopts a matching design of a sliding protrusion 413 and a limiting slot 321, wherein the linkage end 412 of each clamping arm 410 is provided with a sliding protrusion 413, and the limiting slots 321 adapted thereto are symmetrically opened on both sides of the connecting plate 320; when the connecting plate 320 slides axially along the guide column 200, the groove wall of the limiting slot 321 will abut and push the sliding protrusion 413, forcing the linkage end 412 to displace. Since the middle part of the clamping arm 410 is rotatably connected to the support column 420, the displacement will be converted into a lever-like rotation of the clamping arm 410, thereby driving the clamping end 411 to move toward or away from each other, thereby clamping or releasing the workpiece; this structure transmits power through rigid contact, which not only ensures the synchronization and reliability of the action, but also reduces movement friction, making the overall mechanism run smoother and suitable for clamping scenarios with limited space. The linkage end 412 of each clamping arm 410 is provided with a sliding protrusion 413 (such as a bump, pin or roller), which can be cylindrical, rectangular or other structures that are adapted to the slide groove. The connecting plate 320 has symmetrically provided limiting slide grooves 321 on both sides. The number and shape of the limiting slide grooves 321 match the sliding protrusions 413 and are generally linear, arc-shaped or oblique grooves. When the connecting plate 320 slides axially (moves up and down) along the guide column 200, the groove wall of the limiting slide groove 321 will abut and push the sliding protrusion 413, forcing the linkage end 412 to follow the movement. Since the middle part of the clamping arm 410 is rotatably connected to the support column 420, the displacement of the sliding protrusion 413 is converted into a lever-like rotation of the clamping arm 410 around the support column 420, thereby driving the clamping end 411 toward or away from the guide column 200.

[0043] like Figure 3As shown, in some embodiments, the two clamping arms 410 are symmetrically arranged on either side of the connecting plate 320 and are capable of opening or closing during movement relative to the guide post 200. The two clamping arms 410 are symmetrically arranged on either side of the connecting plate 320. When the connecting plate 320 moves axially along the guide post 200, the linkage ends 412 of the clamping arms 410 cooperate with the sliding protrusions 413 and the limiting slide grooves 321 to cause the two clamping arms 410 to rotate synchronously around the support post 420, thereby achieving synchronous opening or closing during movement relative to the guide post 200, ensuring the stability and accuracy of the clamping action.

[0044] like Figure 3 As shown, in some embodiments, the clamping assembly 400 further includes a pressing head 430, each of the clamping ends 411 being connected to a pressing head 430. The pressing head 430 is configured to abut against the control board 20 when approaching the guide post 200. The pressing head 430 may be made of a flexible material. When the clamping arm 410 is closed, the pressing head 430 moves with the clamping end 411 and abuts against the surface of the control board 20. The pressing head 430 is made of a flexible material, which can provide stable contact pressure while avoiding surface damage caused by rigid contact, making it suitable for clamping precision workpieces.

[0045] like Figure 3 and Figure 4As shown, in some embodiments, the clamping assembly 400 further includes a rolling member 440, and the rolling member 440 is rotatably connected to the side of the connecting plate 320 facing the base 100. The driving assembly 500 includes a wedge 510 and a driving member 520. The driving member 520 is provided on the base 100 and connected to the wedge 510. The side of the wedge 510 facing the rolling member 440 is provided with a guide slope 511. The wedge 510 can be driven by the driving member 520 to move closer to or away from the rolling member 440. When the wedge When the wedge-shaped member 510 approaches the rolling member 440, the rolling member 440 can overcome the elastic force of the elastic member under the abutment of the guide slope 511 and roll upward along the guide slope 511 and at the same time drive the connecting plate 320 to rise until the wedge-shaped member 510 moves to the second position; when the wedge-shaped member 510 moves away from the rolling member 440, the rolling member 440 can roll downward along the guide slope 511 under the elastic force of the elastic member 310 and drive the connecting plate 320 to descend until the wedge-shaped member 510 moves to the first position. When the driver 520 pushes the wedge 510 toward the rolling element 440, the rolling element 440 is abutted by the guide slope 511, overcoming the elastic force of the elastic element 310 and rolling upward along the slope, thereby driving the connecting plate 320 upward until the wedge 510 reaches the second position (clamping arm 410 closed state). Conversely, when the driver 520 drives the wedge 510 away from the rolling element 440, the restoring force of the elastic element 310 causes the rolling element 440 to roll downward along the slope, and the connecting plate 320 descends accordingly until the wedge 510 returns to the first position (clamping arm 410 open state). This structure achieves a stable and controllable clamping action through the mechanical force amplification of the wedge slope.

[0046] like Figure 1 、 Figure 2 and Figure 4As shown, in some embodiments, the drive assembly 500 further includes a fixed seat 600 disposed on the base 100. The drive member 520 is movably disposed through the fixed seat 600. One end of the drive member 520 is connected to the wedge member 510, and the other end of the drive member 520 is operable to drive the movement of the wedge member 510. The drive assembly 500 further includes a fixed seat 600 mounted on the base 100. The drive member 520 slidably passes through the fixed seat 600. One end of the drive member 520 is connected to the wedge member 510, and the other end extends externally for an operator to apply force or connect to a power source (such as a cylinder, motor, etc.). By pushing and pulling the drive member 520, the wedge member 510 can be driven to move along the fixed seat 600, thereby precisely controlling the raising and lowering of the rolling element 440 and the opening and closing of the clamping assembly 400. This structure enhances drive stability and facilitates manual or automated operation. In some embodiments, the drive member 520 can be a toggle clamp.

[0047] like Figure 3 and Figure 4 As shown, in some embodiments, the driving member 520 is a motor and can drive the wedge member 510 to perform telescopic motion to move closer to or away from the rolling member 440. The driving member 520 uses a motor (such as a servo motor, a stepper motor or a linear motor) and drives the wedge member 510 to perform linear reciprocating motion through a transmission mechanism (such as a screw, a gear rack or a connecting rod) to move it closer to or away from the rolling member 440. The rotational motion of the motor is converted into the telescopic motion of the wedge member 510, thereby accurately controlling the lifting and lowering of the rolling member 440 and the opening and closing state of the clamping arm 410. This design can realize automated control, improve the accuracy and response speed of the clamping action, and is suitable for scenarios requiring high-frequency or programmed operations.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments, the clamping device 10 further includes a limiting column 700, which is provided on the base 100 and is used to abut against the edge of the control panel 20 to achieve the limitation and positioning of the control panel 20. The clamping device 10 further includes a limiting column 700 fixed to the base 100, which can be vertically arranged and abut against the side edge of the control panel 20. When the control panel 20 is raised and lowered with the rolling element 440, the limiting column 700 constrains the horizontal displacement of the control panel 20 through physical contact, ensuring that it moves precisely within the preset path to avoid deflection or shaking. This structure is simple and reliable, which not only realizes the guiding and positioning of the control panel 20, but also enhances the stability during the clamping process. It is particularly suitable for assembly or processing scenarios with high requirements for position accuracy.

[0049] like Figure 2As shown, in some embodiments, the clamping device 10 also includes a positioning column 800, which is provided on the base 100 and is used to be inserted into the positioning hole on the control board 20 to achieve the limitation and positioning of the control board 20. The clamping device 10 also includes a positioning column 800 fixed to the base 100, which can be set vertically and matched with the positioning hole on the control board 20. When the control board 20 moves with the rolling element 440, the positioning column 800 is inserted into the positioning hole to form a plug-in limiting structure, which effectively constrains the horizontal freedom of the control board 20 and ensures its precise movement along the preset trajectory. This design achieves dual positioning (vertical limitation + horizontal anti-deflection) through mechanical coordination, significantly improving the repeatability and anti-interference ability of the control board 20, and is particularly suitable for high-precision assembly or automated production lines that require frequent reset.
