Description

Technical Field

[0001] This application relates to a clamping device, belonging to the field of mechanical clamping technology. Background Technology

[0002] A screen printing plate, also known as a silkscreen printing plate, is a medium for transferring patterns. In high-precision manufacturing fields such as photovoltaics, electronic printing, and thick-film circuits, the accuracy, uniformity, and consistency of printing directly determine the electrical performance (such as conductivity, resistance, and conversion efficiency) and reliability of the product. Printing typically requires high-precision screen printing plates as the pattern carrier. During the screen printing process, the plate needs to be precisely fixed on the worktable; this is a prerequisite for creating a high-precision screen printing plate.

[0003] In existing technologies, the screen frame is fixed by directly pressing locating pins into the screen and baffle to clamp and secure it. However, this method has several significant drawbacks: First, during the locking process, the traditional locating pins are completely fixed and cannot move. This makes it difficult to align the locating pins with the locating holes on the screen frame, leading to misalignment during clamping and reduced clamping accuracy and efficiency. Second, the screen frame can deform, significantly increasing the difficulty of aligning the locating pins with the locating holes. Traditional rigid clamping methods cannot compensate for this deformation, potentially causing stress concentration or even damage to the screen.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0005] The purpose of this application is to provide a clamping device that can quickly and accurately clamp a target object, thereby improving clamping efficiency.

[0006] The objective of this application is achieved through the following technical solution: a clamping device comprising two clamping mechanisms, the two clamping mechanisms being arranged opposite to each other to form a clamping space capable of clamping a target object, at least one of the clamping mechanisms being movable under external force to change the size of the clamping space; wherein each of the clamping mechanisms comprises: Clamping components; A positioning component, connected to the clamping member, and configured to engage with a mating component of the target object for positioning; and A rotating component, connected to the clamping component, is configured to drive the clamping component to rotate under external force, thereby driving the positioning component to rotate, so that the positioning component and the mating component complete positioning engagement.

[0007] In one embodiment, the clamping member has a center point along its length, and the rotating fitting is mounted at the center point.

[0008] In one embodiment, the clamping member has a mounting hole that coincides with the center point; One end of the rotating component extends into the mounting hole to connect with the clamping component, while the other end of the rotating component is exposed outside the mounting hole.

[0009] In one embodiment, the clamping member has a connecting end face facing the clamping space, and the positioning component is mounted on the connecting end face; The number of positioning components is set to two or more, and the two or more connecting end faces are distributed along the length direction.

[0011] In one embodiment, the positioning member protrudes outward from the connecting end.

[0012] In one embodiment, each of the positioning components includes a positioning element, which is separately disposed from the clamping element.

[0013] In one embodiment, the positioning element includes a support body connected to the connecting end face and a positioning body connected to the support body; The positioning element is configured to engage with the mating component for positioning. The abutment is configured to abut against the end of the mating member when the positioning body is engaged with the mating member for positioning.

[0014] In one embodiment, the clamping device further includes a drive mechanism connected to one of the clamping mechanisms and configured to drive the connected clamping mechanism to move relative to the other clamping mechanism.

[0015] In one embodiment, the driving mechanism includes a driving member and a connecting shaft connected to the driving member, and the clamping member is connected to the connecting shaft.

[0016] Compared with the prior art, this application has the following advantages: By providing two clamping mechanisms, which are arranged opposite to each other to form a clamping space capable of clamping the target object, at least one clamping member can move under external force to adjust the size of the clamping space, thereby allowing the target object to be placed in the clamping space and adjusting the clamping according to the size of the target object; each clamping mechanism includes a clamping member, a positioning component, and a rotating component. When the clamping member clamps the target object, the positioning component can cooperate with the mating component on the target object for positioning. When the positioning component and the mating component are not perfectly aligned, the rotating component can drive the clamping member to rotate under external force to drive the positioning component to rotate, thereby adjusting the angle of the positioning component relative to the mating component, so that the positioning component can be perfectly aligned with the mating component, thereby improving clamping accuracy and ensuring clamping efficiency.

[0024] Please see Figures 1 to 4 As shown, in a preferred embodiment of this application, the clamping device 100 is used to clamp and fix the target object 200 while also positioning it. In this embodiment, the target object 200 is a screen printing plate, which is used in the field of laser printing. In other embodiments, the target object 200 may be other types; no specific limitation is made here regarding the target object 200 or its application field, depending on the actual situation. In the following embodiments, the target object 200 is taken as a screen printing plate for specific details and explanation. In this case, the target object 200 has an exposure surface 201 that cooperates with the laser exposure 300.

[0025] Specifically, the clamping device 100 includes two clamping mechanisms 1, which are arranged opposite to each other to form a clamping space that can clamp the target object 200. At least one clamping mechanism 1 can move under external force to change the size of the clamping space, thereby facilitating the placement of the target object 200. The size of the clamping space can be adjusted according to the size of the target object 200 to adapt to different models of target objects 200, making it faster and more convenient.

[0026] In one embodiment, the external force driving the clamping mechanism 1 to move can be human force. That is, a force is applied to the clamping mechanism 1 by a person, thereby driving the clamping mechanism 1 to move.

[0027] In another embodiment, the external force driving the clamping mechanism 1 to move is a mechanical force. In this case, the clamping device 100 also includes a driving mechanism 2, which is connected to one of the clamping mechanisms 1 and configured to drive the clamping mechanism 1 connected thereto to move relative to the other clamping mechanism 1.

[0028] For example, two clamping mechanisms 1 are distributed along the length of the target object 200 (as shown by arrow a in the figure), located at the first and second ends of the target object 200. A drive mechanism 2 is connected to the clamping mechanism 1 at the first end, while the clamping mechanism 1 at the second end is fixedly connected. Thus, when clamping the target object 200, the second end of the target object 200 can be first aligned with the clamping mechanism 1 at the second end, thereby achieving pre-positioning of the target object 200 during clamping. Then, the drive mechanism 2 drives the clamping mechanism 1 at the first end to move towards the clamping mechanism 1 at the second end until the clamping mechanism 1 at the first end clamps with the first end, thereby achieving clamping and positioning of the target object 200.

[0029] As described above, the clamping mechanism 1 located at the second end of the target object 200 is fixedly connected. This fixed connection can be achieved by the clamping mechanism 1 located at the second end of the target object 200 being fixedly mounted on the external equipment frame. Correspondingly, the clamping mechanism 1 located at the first end of the target object 200 is connected to the drive mechanism 2 and moves under the drive of the drive mechanism 2. Therefore, the clamping mechanism 1 located at the first end of the target object 200 is slidably connected to the external equipment frame.

[0030] In other embodiments, two drive mechanisms 2 may also be provided. That is, the number of drive mechanisms 2 corresponds to the number of clamping mechanisms 1, and each drive mechanism 2 drives the clamping mechanism 1 connected to it to move.

[0031] The drive mechanism 2 includes a drive component and a connecting shaft connected to the drive component, with the clamping component 11 connected to the connecting shaft. Alternatively, the drive component can be mounted on an external equipment frame for secure mounting. One end of the connecting shaft is connected to the output shaft of the drive component, and the other end is connected to the clamping mechanism 1.

[0032] In this embodiment, the driving component is a cylinder. In other embodiments, the driving component can also be a hydraulic cylinder, a linear motor, or other linear drive device. Alternatively, the driving component can also be a rotary drive device, such as a motor. In this case, a transmission component needs to be provided between the driving component and the connecting shaft to convert the rotational motion of the driving component into linear motion. This transmission component can be a lead screw or similar conventional structure, and will not be described in detail here.

[0033] Each clamping mechanism 1 includes a clamping member 11 and a positioning component 12. The positioning component 12 is connected to the clamping member 11 and is configured to cooperate with the mating component 202 of the target object 200 for positioning, thereby achieving both clamping and positioning of the target object 200.

[0034] The clamping member 11 has a connecting end face facing the clamping space, and the positioning component 12 is mounted on the connecting end face. In this embodiment, there are two or more positioning components 12, and the two or more connecting end faces are distributed along their length. By providing two or more positioning components 12, different sizes of target objects 200 can be accommodated.

[0035] That is, one positioning component 12 is adapted to the smaller target object 200, and the other positioning component 12 is adapted to the larger target object 200, etc.

[0036] Correspondingly, the number of cooperating components 202 also corresponds to the number of positioning components 12, so as to cooperate with different positioning components 12 for positioning.

[0037] Each positioning component 12 includes a positioning element 121, and each mating component 202 includes a mating element 2021. In this embodiment, each positioning component 12 has two positioning elements 121, and correspondingly, each mating component 202 also has two mating elements 2021 to improve positioning accuracy. In other embodiments, the number of positioning elements 121 and mating elements 2021 may also be other, such as three or four, etc., and is not specifically limited here, but depends on the actual situation.

[0038] Furthermore, one of the positioning element 121 and the mating element 2021 is a positioning pin, and the other of the positioning element 121 and the mating element 2021 is a positioning groove.

[0039] In one embodiment, the positioning member 121 and the clamping member 11 are integrally formed. That is, in this embodiment, the positioning member 121 protrudes outward from the connecting end.

[0040] In another embodiment, the positioning member 121 and the clamping member 11 are separately disposed. In this case, the positioning member 121 includes a support body 1211 connected to the connecting end face and a positioning body 1212 connected to the support body 1211. The positioning body 1212 is configured to cooperate with the mating member 2021 for positioning, and the support body 1211 is configured to abut against the end of the mating member 2021 when the positioning body 1212 is engaged with the mating member 2021 for positioning.

[0041] Furthermore, the clamping member 11 is also provided with an indicator 14, which corresponds to the position of the positioning member 121, thereby indicating the specific position of the positioning member 121, which facilitates the rapid positioning between the positioning member 121 and the mating member 2021.

[0042] As mentioned above, the target object 200 is a screen. The screen may deform, which greatly increases the difficulty of aligning the positioning pin with the positioning hole on the screen. This can lead to the positioning part 121 and the mating part 2021 not being fully aligned, thus affecting the alignment accuracy.

[0043] To prevent the above phenomenon from occurring, the clamping mechanism 1 in this embodiment further includes a rotating member 13, which is connected to the clamping member 11 and is configured to drive the clamping member 11 to rotate under external force to drive the positioning component 12 to rotate, so that the positioning component 12 and the mating component 202 can complete the positioning and mating.

[0044] That is, when the positioning component 121 and the mating component 2021 cannot be fully aligned, the external force drives the rotating component 13 to rotate, thereby driving the clamping component 11 to rotate, and then driving the positioning component 12 to rotate at a certain angle to adapt to the deformation of the target object 200 and eliminate the positioning error between the positioning component 121 and the mating component 2021 caused by the deformation of the target object 200.

[0045] The external force used to drive the rotating component 13 to rotate can also be human or mechanical force, the same as the external force used to drive the clamping mechanism 1 to move, and will not be described in detail here. In this embodiment, the external force is also described as mechanical force. At this time, an external driving device is provided to dock with the rotating component 13.

[0046] In this embodiment, the clamping member 11 has a center point along its length, and the rotating mating member 2021 is installed at the center point to further ensure the alignment accuracy between the positioning component 12 and the mating component 202.

[0047] The clamping member 11 has a mounting hole that coincides with the center point. One end of the rotating member 13 extends into the mounting hole to connect with the clamping member 11, while the other end of the rotating member 13 is exposed outside the mounting hole, so that an external drive device can quickly and accurately dock with the rotating member 13 for driving.

[0048] In summary: By providing two clamping mechanisms 1, which are arranged opposite each other to form a clamping space capable of clamping the target object 200, at least one clamping member 11 can move under external force to adjust the size of the clamping space, thereby allowing the target object 200 to be placed within the clamping space and adjusting the clamping of the target object 200 according to its size; each clamping mechanism 1 includes a clamping member 11, a positioning component 12, and a rotating component 13. When the clamping member 11 clamps the target object 200, the positioning component 12 can cooperate with the mating component 202 on the target object 200 for positioning. When the positioning component 12 and the mating component 202 are not perfectly aligned, the rotating component 13 can drive the clamping member 11 to rotate under external force, thereby driving the positioning component 12 to rotate, adjusting the angle of the positioning component 12 relative to the mating component 202, so that the positioning component 12 can be completely aligned with the mating component 202, thereby improving clamping accuracy and ensuring clamping efficiency.

[0049] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
