The jig includes a main body for carrying a workpiece and a pressure piece that can be turned relative to the main body. The pressure piece is turned away from the main body to open the jig to pick up and place the workpiece. The pressure piece is turned close to the main body to close the jig, and the pressure piece presses the workpiece against the main body.

[0050] The technical solution of the present application will be described below in conjunction with the drawings in the implementation modes of the present application. Obviously, the described implementation modes are only part of the implementation modes of the present application, rather than all the implementation modes.

[0051] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a component centered. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0052] In addition, the terms "first", "second", "third", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "perpendicular" is used to describe the ideal state between two components. In actual production or use, there may be a state that is approximately perpendicular between the two components. For example, in combination with numerical descriptions, perpendicularity may refer to the angle between two straight lines being between 90°±10°, perpendicularity may also refer to the dihedral angle between two planes being between 90°±10°, and perpendicularity may also refer to the angle between a straight line and a plane being between 90°±10°. The two components described as "perpendicular" may not be absolute straight lines or planes, but may be roughly straight lines or planes. From a macroscopic point of view, the components can be considered "straight lines" or "planes" if the overall extension direction is a straight line or a plane. The terms "X direction", "Y direction" or "Z direction" refer to all directions parallel to the coordinate axes X, Y, and Z in the accompanying drawings, including positive and negative directions.

[0053] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0054] At present, in the production process of electronic products, the workpiece needs to be positioned by a jig before it can be processed or inspected. For example, when inspecting a mobile phone screen, the jig needs to be positioned by the jig before the mobile phone screen can be inspected. However, in the process of positioning the mobile phone screen by the jig, the jig needs to be opened before the mobile phone screen can be placed in the jig. In the current related technologies, the way of opening the jig is generally inefficient.

[0055] In view of this, it is necessary to provide a clamping device that can improve the efficiency of opening a jig. The clamping device is used to open the jig. The jig includes a main body that carries a workpiece and a pressure piece that can be flipped relative to the main body. The pressure piece flips away from the main body to open the jig to pick up and place the workpiece. The pressure piece flips close to the main body to close the jig, and the pressure piece presses the workpiece on the main body. The clamping device includes a base, a lever and a driving assembly. The base is used to carry the jig. The lever is arranged on the base and can rotate between a first position and a second position relative to the base. The driving assembly includes a gear, a rack and a first driver. The gear is coaxially arranged with the lever, the rack is meshed with the gear, and the rack is connected to the first driver. The first driver is used to drive the rack to translate to drive the gear and the lever to rotate. When the lever is in the first position, the jig is placed on the base so that the pressure piece is located on the side of the lever facing away from the base. When the lever is turned from the first position to the second position, the lever flips the pressure piece so that the pressure piece is away from the main body to open the jig.

[0056] The above-mentioned declamping device opens the jig in the following manner: when the lever is in the first position, the jig is placed on the base, and the pressure piece is located on the side of the lever facing away from the base. Then the driving assembly drives the lever to rotate, so that the lever turns from the first position to the second position, and then the lever flips the pressure piece, so that the pressure piece moves away from the main body, thereby opening the jig so that the workpiece can be placed in the jig. After the jig leaves the base, the driving assembly drives the lever to reset, in preparation for opening the next jig, to achieve a cyclic operation. In addition, the declamping device can convert the translational motion into a rotational motion through the cooperation of the gear and the rack, thereby eliminating the need to use a rotary drive to drive the lever to rotate, which can simplify the structure or save space. In summary, the declamping device of the present application realizes the automatic opening of the jig and improves the efficiency of opening the jig.

[0057] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0058] See also Figures 1 to 5 In one embodiment of the present application, a declamping device 100 is provided for opening a fixture 200 to allow a workpiece 300 to be placed into the fixture 200 or to be removed from the fixture 200. The declamping device 100 can automatically open the fixture 200 to improve the opening efficiency of the fixture 200.

[0059] The jig 200 includes a main body 201 and a pressing piece 202. The main body 201 is used to carry the workpiece 300, and the pressing piece 202 can be flipped relative to the main body 201. When the pressing piece 202 flips in a direction away from the main body 201, the jig 200 is opened to allow the workpiece 300 to be placed in the main body 201 or taken out from the main body 201. That is, when the jig 200 is opened, the pressing piece 202 will not interfere with the placement and taking of the workpiece 300. When the pressing piece 202 flips in a direction close to the main body 201, the jig 200 is closed. At this time, the pressing piece 202 presses down the workpiece 300 on the main body 201, thereby pressing the workpiece 300 on the main body 201 to position the workpiece 300. That is, when the jig 200 is closed, the workpiece 300 cannot be taken out of the main body 201, nor can the workpiece 300 be placed in the main body 201. As an illustrative example, the workpiece 300 is a mobile phone screen, and the mobile phone screen is positioned by the jig 200 and then inspected.

[0060] The clamping device 100 includes a base 10, a lever 20 and a driving assembly 30. The base 10 is used to carry the fixture 200. The lever 20 is arranged on the base 10 and can rotate between a first position and a second position relative to the base 10. The driving assembly 30 is arranged on the base 10 and is used to drive the lever 20 to rotate. The clamping device 100 is used as follows: the driving assembly 30 first drives the lever 20 to rotate to the first position, and then the fixture 200 in the closed state is placed on the base 10. At this time, the pressing piece 202 is located on the side of the lever 20 facing away from the base 10. Then, the driving assembly 30 drives the lever 20 to rotate from the first position to the second position, so that the lever 20 flips the pressing piece 202 in a direction away from the main body 201, thereby opening the fixture 200; when the fixture 200 leaves the base 10, the driving assembly 30 drives the lever 20 to return to the first position to prepare to open the next fixture 200, thereby realizing a cyclic operation. In summary, the clamping device 100 realizes the automatic opening of the fixture 200 and improves the opening efficiency of the fixture 200.

[0061] Optionally, the pressing member 202 of the fixture 200 includes a bracket 2021, a pressing block 2022 and a handle 2023. The bracket 2021 is rotatably connected to the main body 201. The pressing block 2022 and the handle 2023 are arranged on the bracket 2021 and rotate with the bracket 2021. The pressing block 2022 plays the role of pressing down the workpiece 300. The handle 2023 extends from the bracket 2021 outside the main body 201 and is used to cooperate with the lever 20, that is, when the fixture 200 is placed on the base 10, only the handle 2023 is located above the lever 20. When the lever 20 rotates, the bracket 2021 and the pressing block 2022 are flipped by applying force to the handle 2023. In addition, if the weight of the bracket 2021 itself can press the workpiece 300, the pressing block 2022 can be omitted, and the bracket 2021 itself replaces the role of the pressing block 2022. It is understandable that when the clamping device 100 is not used, the user can also turn over the pressing piece 202 by hand through the handle 2023 , but the efficiency of manual work is low.

[0062] In some embodiments, the driving assembly 30 includes a gear 31, a rack 32, and a first driver 33. The gear 31 is coaxially arranged with the lever 20 and rotates synchronously. The rack 32 is meshed with the gear 31. The rack 32 is connected to the first driver 33. The first driver 33 is used to drive the rack 32 to translate, so as to drive the gear 31 to rotate, thereby causing the lever 20 to rotate synchronously with the gear 31. The cooperation between the gear 31 and the rack 32 can convert the translational motion into a rotational motion, thereby eliminating the need for a rotational driver. As an exemplary example, the first driver 33 is a cylinder.

[0063] Optionally, the gear 31 and the lever 20 rotate around the horizontal axis in the X direction, the rack 32 extends in the vertical Z direction, and the first driver 33 drives the rack 32 to rise and fall to drive the gear 31 and the lever 20 to rotate. It can be understood that in other embodiments, the rack 32 extends in the horizontal Y direction, the Y direction is perpendicular to the X direction, and the first driver 33 drives the rack 32 to move horizontally to drive the gear 31 and the lever 20 to rotate.

[0064] In some embodiments, the driving assembly 30 may also be a motor (not shown), and the motor drives the lever 20 to rotate.

[0065] In some embodiments, the jig 200 is provided with a plurality of pressing members 202, and the plurality of pressing members 202 are used to jointly press the workpiece 300 onto the main body 201. Therefore, correspondingly, the gears 31, the racks 32 and the levers 20 also have the same number of multiple and one-to-one correspondence, that is, each gear 31 is coaxially arranged with a lever 20 and rotates synchronously, and each gear 31 is meshed with a rack 32. The driving assembly 30 also includes a connecting member 34, and the first driver 33 connects the plurality of racks 32 through the connecting member 34 to drive the plurality of racks 32 to translate synchronously, so that the plurality of gears 31 rotate synchronously, and then the plurality of levers 20 synchronously flip the plurality of pressing members 202 in the jig 200. Compared with the motor drive, the cooperation of the gears 31, the racks 32, the connecting member 34 and the first driver 33 can more easily realize the synchronous flipping of the plurality of levers 20, which can be realized with only one driver, thereby simplifying the number of drivers and simplifying the structure.

[0066] Optionally, the handles 2023 of the plurality of pressing members 202 in the fixture 200 are arranged in the Y direction, the plurality of levers 20, the plurality of gears 31 and the plurality of racks 32 are also arranged in the Y direction, and the length of each rack 32 is extended in the Z direction, the first driver 33 drives the plurality of racks 32 to rise in the Z direction to rotate each lever 20, so that each lever 20 flips each pressing member 202 to open the fixture 200, and the first driver 33 drives the plurality of racks 32 to descend in the Z direction to reset each lever 20. As an exemplary example, the number of the pressing member 202, the lever 20, the gear 31 and the rack 32 is three respectively.

[0067] Further optionally, the connecting member 34 is provided with an avoidance groove 341 at each gear 31, and the avoidance groove 341 can accommodate the gear 31, so that the connecting member 34 can avoid the gear 31 when moving along the Z direction, avoiding interference between the connecting member 34 and the gear 31, so as to improve the operating reliability of the driving assembly 30.

[0068] In addition, the directions in which the various pressing members 202 are flipped can be different or the same, for example, Figure 2As shown, part of the pressing pieces 202 need to rotate around direction A to open the fixture 200, and the remaining pressing pieces 202 need to rotate around direction B to open the fixture 200. Directions A and B are clockwise and counterclockwise to each other. For example, all the pressing pieces 202 need to rotate around direction A or direction B to open the fixture 200. Therefore, it is necessary to set the position of the corresponding rack 32 according to the required rotation direction of each gear 31. For example, if the gear 31 rotates around the A direction to open the fixture 200, the corresponding rack 32 needs to be set on the side of the gear 31 along the negative direction of Y (the left side of the gear 31 in the figure), so that the rack 32 can rotate around the A direction when the first driver 33 drives the rack 32 to rise along the Z direction. For another example, if the gear 31 rotates around the B direction to open the fixture 200, the corresponding rack 32 needs to be set on the side of the gear 31 along the positive direction of Y (the right side of the gear 31 in the figure), so that the rack 32 can rotate around the B direction when the first driver 33 drives the rack 32 to rise along the Z direction.

[0069] It is easy to understand that in other embodiments, when the fixture 200 is opened, the driving direction of the rack 32 by the first driver 33 can also be changed to downward, and the position of the rack 32 can also be changed accordingly, or the length of each rack 32 can also be extended in other directions, as long as the gear 31 can be driven to rotate in the desired direction.

[0070] In some embodiments, Figure 4 , Figure 5 and Figure 7 As shown, the disassembling device 100 also includes two clamping assemblies 40, and the two clamping assemblies 40 are respectively arranged on opposite sides of the base 10 along the Y direction. Each clamping assembly 40 includes a second driver 41 and a clamp 42, and the clamp 42 is connected to the second driver 41. When the fixture 200 is placed on the base 10, the second driver 41 drives the clamp 42 to move along the Y direction, so that the clamps 42 on both sides clamp the main body 201 of the fixture 200 together to position the main body 201, avoid shaking of the main body 201, and improve the stability of the main body 201.

[0071] In some embodiments, the base 10 can carry multiple jigs 200 at the same time, each clamp 42 includes a connecting portion 421 and multiple clamping blocks 422, each clamping block 422 corresponds to a jig 200, and multiple clamping blocks 422 are arranged on the connecting portion 421, and the connecting portion 421 is connected to the second driver 41. The second driver 41 drives the multiple clamping blocks 422 to move synchronously through the connecting portion 421, so that the clamping blocks 422 on the opposite sides of each jig 200 move toward each other to clamp the main body 201 of the jig 200, so as to synchronously position multiple jigs 200. As an illustrative example, the base 10 can carry two jigs 200 at the same time.

[0072] In some embodiments, each clamping block 422 is provided with a groove 4221, and when the clamping block 422 clamps the main body 201 of the fixture 200, the groove 4221 is used to accommodate part of the main body 201 to limit the main body 201. The groove 4221 passes through both ends of the clamping block 422 along the X direction, and the groove wall of the groove 4221 can limit the main body 201 in the Z direction to prevent the main body 201 from shaking in the Z direction.

[0073] In some embodiments, Figure 4 As shown, the base 10 is provided with a first sensor 11, which is provided at the position where the base 10 carries the jig 200. The first sensor 11 is used to sense whether the base 10 carries the jig 200. For example, when the first sensor 11 senses that there is a jig 200, it indicates that the jig 200 is placed on the base 10. At this time, the driving component 30 drives the lever 20 to rotate to flip the pressing piece 202, thereby opening the jig 200. When the first sensor 11 does not sense that there is a jig 200, it indicates that the jig 200 is removed from the base 10. At this time, the driving component 30 drives the lever 20 to reset. As an exemplary example, the first sensor 11 is a laser sensor.

[0074] In some embodiments, Figure 4 As shown, the base 10 is provided with a second sensor 12, which is provided on the base 10, and is used to sense whether the pressing piece 202 is flipped into place. The second sensor 12 is located below the pressing piece 202 when the jig 200 is in the open state, and only when the pressing piece 202 is flipped into place away from the main body 201, the pressing piece 202 will enter the upper sensing area of ​​the second sensor 12, and the second sensor 12 will sense the pressing piece 202 at this time, that is, indicating that the pressing piece 202 is flipped into place and the jig 200 is opened. If the pressing piece 202 is not flipped into place, the pressing piece 202 will not enter the upper sensing area of ​​the second sensor 12, and the second sensor 12 will not sense the pressing piece 202 at this time, that is, indicating that the pressing piece 202 is not flipped into place, and the jig 200 is not fully opened.

[0075] Optionally, the second sensor 12 can be conductively connected to a robot (not shown). When the second sensor 12 senses that the pressing piece 202 is flipped into place, the robot automatically places the workpiece 300 into the opened fixture 200 to improve automation efficiency.

[0076] In some embodiments, Figure 1As shown, the declamping device 100 further includes a transport module 50, and the base 10 is disposed on the transport module 50. The transport module 50 is used to drive the base 10 to move so as to move the fixture 200 and the workpiece 300. Optionally, the transport module 50 translates the base 10 along the X direction so that the base 10 moves between the open position and other process positions. When the transport module 50 moves the base 10 to the open position, the base 10 receives the fixture 200 to be opened and opens the fixture 200. Then, the transport module 50 moves the base 10 and the opened fixture 200 to other process positions for other processing or inspection operations.

[0077] In some embodiments, Figure 6 As shown, the lever 20 includes a rod body 21 and a plurality of shifting blocks 22. One end of the rod body 21 is rotatably connected to the base 10 and the gear 31. One end of the rod body 21 away from the base 10 is connected to one of the plurality of shifting blocks 22. The sizes of the plurality of shifting blocks 22 are different. Each shifting block 22 is detachably arranged on the rod body 21 to replace the shifting block 22 on the rod body 21, so that the jigs 200 of different sizes can be adapted by each shifting block 22. Optionally, the lengths of each shifting block 22 are different. Since the positions of the handle 2023 are relatively different when the jigs 200 of different sizes are placed on the base 10, resulting in different distances between the handle 2023 and the rod body 21, a sufficiently long shifting block 22 can be selected according to the distance between the handle 2023 and the rod body 21, so that the lever 20 can always contact the pressing piece 202 during the process of flipping the pressing piece 202, thereby flipping the pressing piece 202 into place.

[0078] In addition, those skilled in the art should recognize that the above embodiments are only used to illustrate the present application and are not intended to be limiting of the present application. As long as they are within the spirit and scope of the present application, appropriate changes and modifications to the above embodiments are within the scope of the present application.
