Description

Technical Field

[0001] This application relates to the field of measuring equipment technology, and in particular to an imaging device. Background Technology

[0002] A vision measuring instrument is a high-precision measuring device based on machine vision and optical imaging technology. It can acquire the geometric dimensions of a workpiece in a non-contact manner. A vision measuring instrument includes a camera, a light source system, a motion system, and a worktable. The camera is used to photograph the workpiece; the light source system can include coaxial light, bottom light, and surface light, used to illuminate the workpiece and highlight its edges or image features; the motion system includes X-axis, Y-axis, and Z-axis drive structures, which control the relative movement of the camera and the worktable in the three mutually perpendicular X, Y, and Z directions, respectively; the worktable is a light-transmitting platform, typically made of glass. In vision measurement, the workpiece is generally placed on the glass surface of the worktable. However, some workpieces, such as flexible electronic devices, may warp or wrinkle when placed on glass, which is detrimental to measurement. In such cases, a glass pressure plate is needed to flatten the workpiece.

[0003] Currently, glass clamps are typically mounted on the worktable via a rotating shaft. When the operator lifts the glass clamp, it rotates around the shaft. During measurement, the workpiece is placed after lifting the glass clamp, and then the glass clamp is lowered to clamp the workpiece. However, glass clamps are difficult to adapt to workpieces of varying thicknesses. Even if some workpieces can deform under the pressure of the glass clamp, certain areas of thicker workpieces cannot be flattened. Utility Model Content

[0009] Two first mounting parts are spaced apart, and two first rotating shafts are respectively located on opposite sides of the first end of the connector. The first end of the connector extends between the two first mounting parts, and each first rotating shaft extends into one of the first mounting parts.

[0010] Two second mounting parts are spaced apart, and two second rotating shafts are respectively located on opposite sides of the second end of the connector. The second end of the connector extends between the two second mounting parts, and each second rotating shaft extends into one of the second mounting parts.

[0011] In one embodiment, a rod is provided in the middle of the connector, and the rod is located between the first fixed seat and the second fixed seat.

[0012] In one embodiment, a detection component is provided on the pressure plate assembly and / or the worktable, the detection component being configured to generate a detection signal when the pressure plate assembly is lifted;

[0013] The imaging device also includes a controller and an alarm, which are respectively installed on the workbench. The controller is electrically connected to the detection component and the alarm, respectively.

[0014] The controller is configured to trigger an alarm when it receives a detection signal and the camera of the imager is located above the pressure plate assembly.

[0015] In one embodiment, the detection component includes a detection circuit, a first contact, and a second contact;

[0016] The first contact is mounted on the fixed frame and has a first contact point. The detection circuit is located inside the fixed frame and is electrically connected to the first contact. The detection circuit is also electrically connected to the controller.

[0017] The second contact is mounted on the workbench and has a second contact point.

[0018] When the pressure plate assembly is in the closed state, the first contact is in contact with the second contact; when the pressure plate assembly is lifted, the first contact disengages from the second contact, and the detection circuit outputs a detection signal to the controller.

[0019] In one embodiment, a damping assembly is connected between the pressure plate assembly and the worktable.

[0020] In one embodiment, the damping assembly includes a first mounting base and a damping rod. The first mounting base is mounted on a workbench, one end of the damping rod is rotatably connected to the first mounting base, and the other end of the damping rod is rotatably connected to the side wall of the fixed frame.

[0021] In one embodiment, a damping rod is connected to each of the two opposite sidewalls of the fixed frame along the first direction, and a first mounting base is connected to the end of each damping rod away from the fixed frame.

The first rotating shaft extends into and is rotatably connected to the first fixed seat, and the second rotating shaft extends into and is rotatably connected to the second fixed seat. After lifting the pressure plate assembly, the operator can place the workpiece on the worktable. When the operator presses down on the pressure plate assembly, the side of the pressure plate assembly with the first fixed seat first contacts the edge of the workpiece. As the operator continues to press down, the connecting member rotates relative to the fixed frame, causing the connecting member to tilt relative to the fixed frame. This tilting of the connecting member allows for different height gaps between the fixed frame and the worktable surface, accommodating workpieces of different thicknesses and ensuring the workpiece is stably flattened, thus improving the applicability of the pressure plate assembly.

[0040] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0041] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] like Figure 1 As shown, the imaging instrument is a high-precision measuring device based on machine vision and optical imaging technology, which can acquire the geometric dimensions of a workpiece in a non-contact manner. The imaging instrument includes a camera 10, a light source system, a motion system 20, and a worktable. The camera 10 is used to photograph the workpiece; the light source system can include coaxial light, bottom light, surface light, etc., used to illuminate the workpiece and highlight its edges or image features; the motion system 20 includes an X-axis drive structure, a Y-axis drive structure, and a Z-axis drive structure, which respectively control the relative movement of the camera 10 and the worktable in the three mutually perpendicular XYZ directions; the worktable is a light-transmitting worktable, generally a glass platform. In imaging measurement, the workpiece is generally placed on the glass surface of the worktable, but some workpieces, such as flexible electronic devices, may warp or wrinkle when placed on a glass surface, which is not conducive to measurement. In this case, a glass pressure plate is needed to flatten the workpiece.

[0045] Currently, glass clamps are typically mounted on the worktable via a pivot, allowing the operator to rotate the clamp around the pivot when lifting it. During measurement, the workpiece is placed after lifting the clamp, and then the clamp is lowered to secure it. However, glass clamps are difficult to adapt to workpieces of varying thicknesses.

[0046] To address the aforementioned issues, this application provides an imaging device in which one side of a pressure plate assembly is rotatably connected to a worktable via multiple rotating shaft assemblies. Each rotating shaft assembly includes a first fixed base, a second fixed base, and a connecting member. The connecting member has a first rotating shaft and a second rotating shaft at its two ends, respectively. The first fixed base is mounted on the fixed frame of the pressure plate assembly, and the second fixed base is mounted on the worktable. The first rotating shaft extends into and is rotatably connected to the first fixed base, and the second rotating shaft extends into and is rotatably connected to the second fixed base. After lifting the pressure plate assembly, the operator can place the workpiece on the worktable. When the operator presses down on the pressure plate assembly, the side of the pressure plate assembly with the first fixed base first contacts the edge of the workpiece. As the operator continues to press down, the connecting member rotates relative to the fixed frame, causing the connecting member to tilt relative to the fixed frame. This tilting of the connecting member allows for different height intervals between the fixed frame and the worktable surface, accommodating workpieces of varying thicknesses and ensuring the workpiece is stably flattened, thus improving the applicability of the pressure plate assembly.

[0047] The specific structure of the imaging device provided in the embodiments of this application will be described below with reference to the accompanying drawings.

[0048] Reference Figure 2 and Figure 3 As shown in the figure, this application embodiment provides an imaging device, including a pressure plate assembly 100 and a worktable. The pressure plate assembly 100 is located above the worktable.

[0049] One side of the pressure plate assembly 100 is rotatably connected to the worktable via multiple rotating shaft assemblies 200. The pressure plate assembly 100 includes a fixed frame 110 and a pressure plate 120 mounted inside the fixed frame 110. For example, Figure 2 As shown, one side of the pressure plate assembly 100 can be rotatably connected to the worktable via two spaced-apart pivot assemblies 200. In one possible implementation, a handle 130 is provided on the side of the pressure plate assembly 100 away from the pivot assemblies 200, allowing the operator to lift the pressure plate assembly 100 by holding the handle 130. Schematably, the fixing frame 110 is a rectangular frame structure with a rectangular opening formed on its inner side. The pressure plate 120 is disposed within the rectangular opening and fixed to the fixing frame 110. The pressure plate 120 can be made of glass or other transparent materials.

[0050] The rotating shaft assembly 200 includes a first fixed base 210, a second fixed base 220, and a connector 230. The first fixed base 210 is installed on one side of the fixed frame 110, and the second fixed base 220 is installed on the workbench. The first end of the connector 230 is provided with a first rotating shaft, and the second end of the connector 230 is provided with a second rotating shaft. The first rotating shaft and the second rotating shaft are arranged parallel to each other. The first rotating shaft extends into the first fixed base 210 and is rotatably connected to the first fixed base 210, and the second rotating shaft extends into the second fixed base 220 and is rotatably connected to the second fixed base 220.

[0051] The first fixed seat 210 can be fastened to the fixed frame 110 with fasteners, and the second fixed seat 220 can also be fastened to the worktable with fasteners. The first and second rotating shafts can be integrally formed on the connector 230, and the extension directions of the first and second rotating shafts can be perpendicular to the length direction of the connector 230, respectively. The fixed frame 110 can rotate relative to the connector 230 around the first rotating shaft, and the connector 230 can rotate relative to the second fixed seat 220 on the worktable around the second rotating shaft, thereby lifting or closing the pressure plate assembly 100.

[0052] Indicatively, the first fixed base 210 is provided with a first mounting hole, and the first rotating shaft of the connector 230 extends into the first mounting hole and is rotatably connected to the first fixed base 210; the second fixed base 220 is provided with a second mounting hole, and the second rotating shaft of the connector 230 extends into the second mounting hole and is rotatably connected to the second fixed base 220.

[0053] A bearing 240 can be installed between the first rotating shaft and the first fixed base 210 to reduce wear on both. Similarly, a bearing 240 can be installed between the second rotating shaft and the second fixed base 220 to reduce wear on both. In other words, the rotating shaft assembly 200 also includes two sets of bearings 240. The first set of bearings 240 is mounted in pairs on the fixed frame 110 via the first fixed base 210, and the second set of bearings 240 is mounted in pairs on the worktable via the second fixed base 220.

[0054] When the operator lifts the pressure plate assembly 100, the engagement between the first rotating shaft and the first fixed seat 210, and the engagement between the second rotating shaft and the second fixed seat 220, allows the pressure plate assembly 100 to flip upwards. After a workpiece is placed on the worktable, the side of the connecting member 230 connected to the fixing frame 110 can be adjusted to a corresponding height according to the thickness of the workpiece. Specifically, when the operator presses down on the pressure plate assembly 100, the connecting member 230 can rotate relative to the pressure plate assembly 100, causing the connecting member 230 to be in an inclined state. With different inclination angles, the distance between the pressure plate assembly 100 and the worktable surface varies. By adjusting the inclination angles of the connecting member 230, the pressure plate assembly 100 can flatten workpieces of different thicknesses.

[0055] In one embodiment, such as Figure 2 and Figure 3 As shown, the first mounting base 210 includes two first mounting portions 211, and the second mounting base 220 includes two second mounting portions 221. There are two first rotating shafts and two second rotating shafts. The two first mounting portions 211 can be integrally formed onto the first mounting base 210, and the two second mounting portions 221 can be integrally formed onto the second mounting base 220.

[0056] Two first mounting portions 211 are spaced apart, and two first rotating shafts are respectively located on opposite sides of the first end of the connector 230. The first end of the connector 230 extends between the two first mounting portions 211, and each first rotating shaft extends into one of the first mounting portions 211.

[0057] Two second mounting portions 221 are spaced apart, and two second rotating shafts are respectively located on opposite sides of the second end of the connector 230. The second end of the connector 230 extends between the two second mounting portions 221, and each second rotating shaft extends into one of the second mounting portions 221.

[0058] Schematic, the two first rotating shafts of connector 230 are arranged coaxially, and the two second rotating shafts of connector 230 are also arranged coaxially. Connector 230 and the two first and two second rotating shafts thereon can together form an "I"-shaped structure. Two first mounting portions 211 are arranged axially spaced along the first rotating shafts, and two second mounting portions 221 are arranged axially spaced along the second rotating shafts. The spacing between the two first mounting portions 211 can match the width of the first end of connector 230, and the spacing between the two second mounting portions 221 can match the width of the second end of connector 230.

[0059] In this embodiment, the two first mounting portions 211 of the first fixing base 210 can restrict the axial movement of the first end of the connecting member 230 along the first rotating shaft, and the two second mounting portions 221 of the second fixing base 220 can restrict the axial movement of the second end of the connecting member 230 along the second rotating shaft. The above arrangement can ensure that the connecting member 230 is reliably connected to the first fixing base 210 and the second fixing base 220 respectively, and ensure that the pressing plate assembly 100 can reliably flip relative to the worktable.

[0060] In one embodiment, as Figure 3 illustrates, a rod body 231 is provided at the middle part of the connecting member 230, and the rod body 231 is located between the first fixing base 210 and the second fixing base 220.

[0061] Illustratively, the middle part of the connecting member 230 can be connected with the middle part of the rod body 231 by means of integral molding. The connecting member 230 forms an approximate "king"-shaped structure. It is worth mentioning that when the pressing plate assembly 100 flips relative to the worktable, the rod body 231 will not interfere with the first fixing base 210 or the second fixing base 220.

[0062] By providing the rod body 231 on the connecting member 230 to increase the local width of the connecting member 230, the structural strength of the connecting member 230 can be improved, which is beneficial to prolonging the service life of the imaging instrument.

[0063] In one embodiment, as Figure 2 and Figure 5 illustrated, the pressing plate assembly 100 and / or the worktable is provided with a detection assembly 300, and the detection assembly 300 is configured to generate a detection signal when the pressing plate assembly 100 is lifted. Specifically, the detection assembly 300 may be provided only on the pressing plate assembly 100, or only on the worktable, or may be provided on both the pressing plate assembly 100 and the worktable respectively. The position of the pressing plate assembly 100 relative to the worktable can be acquired through the detection assembly 300, so that whether the pressing plate assembly 100 is in a lifted state can be determined.

[0064] The imaging instrument further comprises a controller and an alarm which are respectively installed on the worktable, and the controller is electrically connected to the detection assembly 300 and the alarm respectively. The controller is configured to control the alarm to give an alarm when the detection signal is received and the camera of the imaging instrument is located above the pressing plate assembly 100.

[0065] In related technologies, when operators lift the pressure plate assembly 100, they may easily overlook the camera above the pressure plate assembly 100, leading to a collision between the pressure plate assembly 100 and the camera, causing damage to the camera. In this embodiment, by setting a detection component 300, the controller can determine whether the pressure plate assembly 100 has been lifted. When the operator lifts the pressure plate assembly 100, the detection component 300 generates a detection signal, which is fed back to the controller. After receiving the detection signal, the controller determines the relative position between the camera and the pressure plate assembly 100 and decides whether to activate the alarm based on the relative position. Specifically, after receiving the detection signal, the controller confirms whether the camera is above the pressure plate assembly 100. If the camera is improperly positioned (i.e., above the pressure plate assembly 100), the controller will activate the alarm to remind the operator to stop lifting the pressure plate assembly 100. This design can prevent the pressure plate assembly 100 from bumping into the camera and causing damage.

[0066] In a specific embodiment, such as Figure 2 and Figure 5 As shown, the detection component 300 includes a detection circuit, a first contact 310, and a second contact 320. The first contact 310 is mounted on the fixed frame 110 and has a first contact point. The detection circuit is disposed inside the fixed frame 110 and is electrically connected to the first contact 310. The detection circuit is also electrically connected to the controller.

[0067] The detection circuit, the first contact 310, and the second contact 320 define a contact circuit. The first contact 310 can be disposed on the side where the fixing frame 110 connects to the first fixing base 210. The first contact 310 is formed of a conductive material, fixed to the surface of the fixing frame 110, and electrically connected to the detection circuit inside the fixing frame 110. At least a portion of the detection circuit can be disposed opposite to the first contact 310. The first contact point can be an electrical contact point fixed on the first contact 310.

[0068] The second contact 320 is mounted on the worktable and has a second contact point. For example, the second contact 320 can be mounted on the worktable via a second mounting base 330. When the pressure plate assembly 100 is in the closed state, the second contact 320 is positioned opposite to the first contact 310. The second contact point can be a resilient electrical contact point provided on the second contact 320.

[0069] When the pressure plate assembly 100 is in the closed state, the first contact and the second contact are in contact. When the pressure plate assembly 100 is lifted, the first contact disengages from the second contact, and the detection circuit outputs a detection signal to the controller.

[0070] Specifically, when the first contact of the first contact 310 contacts the second contact of the second contact 320, the detection circuit is in a connected state; when the first contact of the first contact 310 is disconnected from the second contact of the second contact 320, the detection circuit is in a disconnected state. The switching between the on and off states of the detection circuit can generate a detection signal; specifically, when the detection circuit is in a disconnected state, the detection circuit generates a detection signal.

[0071] Specifically, the positions of the first contact 310 and the second contact 320 are adjusted. For example, the contact position of the second contact 320 with the first contact 310 is slightly below the first contact 310. When the pressure plate assembly 100 is in the closed state, the two contacts are in contact, and the detection circuit is in a connected state. When the operator lifts the pressure plate assembly 100, the first contact 310 and the second contact 320 move away from each other, causing them to stop contacting each other. At this time, the detection circuit changes from a connected state to an open state, thereby outputting a detection signal. The purpose of this detection signal is to inform the controller that the current pressure plate assembly 100 is in the lifting state. It is necessary to determine the relative position between the camera and the pressure plate assembly 100. Based on the relative position, it is determined whether to control the alarm to sound an alarm. If the camera is above the pressure plate assembly 100, an alarm can be sounded to inform the operator to stop lifting the pressure plate assembly 100.

[0072] In other embodiments, the detection circuit may also be mounted on the workbench and electrically connected to the second contact point.

[0073] In other embodiments, the detection component 300 may also employ a non-contact optical measurement element, such as a ranging element, which may be set on a worktable to monitor positional changes between itself and the pressure plate assembly 100, and generate a detection signal when a certain threshold is exceeded.

[0074] In one embodiment, such as Figure 2 and Figure 6 As shown, a damping assembly 400 is connected between the pressure plate assembly 100 and the worktable.

[0075] Understandably, the damping component 400 provides resistance to the movement of the pressure plate assembly 100. The damping component 400 is designed between the pressure plate assembly 100 and the worktable. When the operator moves the pressure plate assembly 100 up and down, the damping component 400 buffers the movement of the pressure plate assembly 100, preventing impacts when the pressure plate assembly 100 closes (such as colliding with the worktable due to excessively rapid descent), or collisions with the camera due to improper camera positioning and excessively rapid lifting. This ensures the service life of the pressure plate assembly 100.

[0076] In a specific embodiment, such as Figure 4As shown, the damping assembly 400 includes a first mounting base 410 and a damping rod 420. The first mounting base 410 is mounted on the workbench, one end of the damping rod 420 is rotatably connected to the first mounting base 410, and the other end of the damping rod 420 is rotatably connected to the side wall of the fixed frame 110.

[0077] For example, the first mounting base 410 can be mounted on the top of the workbench with fasteners. When the pressure plate assembly 100 is in the closed state, the first mounting base 410 is located on one side of the pressure plate assembly 100. Optionally, a pneumatic rod (nitrogen spring) can be used as the damping rod 420. The two ends of the pneumatic rod are respectively provided with connectors in opposite directions. One end of the connector is rotatably connected to the first mounting base 410, and the other end of the connector is rotatably connected to the side wall of the fixed base. When the operator moves the pressure plate assembly 100 up and down, the damping rod 420 rotates relative to the first mounting base 410 and the pressure plate assembly 100.

[0078] Optionally, a control valve can be installed inside the pneumatic rod to control whether the pneumatic rod can freely extend and retract. When the pressure plate assembly 100 is raised to a certain height, that is, after the pneumatic rod is stretched to a certain length, the control valve is triggered, thereby preventing the pneumatic rod from automatically retracting. This provides a certain degree of support for the pressure plate assembly 100, maintaining its raised state in the absence of external force. When the pressure plate assembly 100 is closed, a downward force is applied to the pressure plate assembly 100 (such as when an operator presses down on the pressure plate assembly 100), thereby triggering the control valve again. At this time, the downward pressure drives the pneumatic rod to retract. Of course, after the control valve is triggered, it can also automatically retract in the absence of external force until the pressure plate assembly 100 is closed or subjected to external force.

[0079] Optionally, there may be two pneumatic rods, which are respectively arranged on opposite sides of the pressure plate assembly 100 to maintain balance when the pressure plate assembly 100 is lifted.

[0080] In this embodiment, when the operator moves the pressure plate assembly 100 up and down, the extension and retraction of the damping rod 420 provides a buffer for the movement of the pressure plate assembly 100.

[0081] In other embodiments, the damping assembly 400 includes a first friction plate mounted on the fixed frame 110 and a second friction plate mounted on the worktable, with the first friction plate abutting against the second friction plate. When the operator moves the pressure plate assembly 100 up and down, the friction between the first and second friction plates provides cushioning for the pressure plate assembly 100.

[0082] In a more specific embodiment, such as Figure 2 , Figure 4 and Figure 6As shown, a damping rod 420 is connected to each of the two opposite sidewalls of the fixed frame 110 along the first direction, and a first mounting base 410 is connected to the end of each damping rod 420 away from the fixed frame 110. The first direction is parallel to the rotation axis of the pressure plate assembly 100.

[0083] Here, the first direction is defined as... Figure 2 The direction indicated by the X-axis. Two damping rods 420 are located on opposite sides of the fixed frame 110 along the first direction. There are also two first mounting seats 410, and each of the two first mounting seats 410 is connected to one of the two damping rods 420. When the operator moves the pressure plate assembly 100 up and down, the two damping rods 420 together provide cushioning for the pressure plate assembly 100.

[0084] The above settings ensure the buffering effect of the pressure plate assembly 100 during its up-and-down movement. Furthermore, the two damping rods 420 make the force on both sides of the fixed frame 110 more uniform, which is beneficial to improving the service life of the pressure plate assembly 100.

[0085] In one embodiment, such as Figure 6 As shown, a support is installed on the worktable and / or the fixed frame 110. When the pressure plate assembly 100 is in the closed state, the non-working area of ​​the worktable and the fixed frame 110 are abutted against each other by the support.

[0086] The support member can be installed only on the worktable or only on the fixed frame 110, or it can be installed on both the worktable and the fixed frame 110. When the support member is installed on the worktable, it protrudes from the top surface of the worktable; when the support member is installed on the fixed frame 110, it protrudes from the main body of the fixed frame 110 facing the worktable. For example, when the support member is installed on the fixed frame 110, there can be four support members, which are respectively installed at the four corners of the fixed frame 110 facing the worktable.

[0087] Those skilled in the art will understand that the working area of ​​the workbench is made of glass. In order to prevent the pressure plate assembly 100 from directly contacting the glass and causing the glass to break, a support is installed on the workbench and / or the fixed frame 110. When the pressure plate assembly 100 is in the closed state, the support is located in the non-working area of ​​the workbench (a location that is not made of glass) to position the pressure plate assembly 100.

[0088] In a specific embodiment, such as Figure 6 As shown, the support is a limit screw 111. The fixed frame 110 has a threaded hole on the side facing the worktable. The limit screw 111 extends into the threaded hole and is threadedly connected to the threaded hole.

[0089] Understandably, by rotating the limit screw 111 to adjust the length of the limit screw 111 extending into the threaded hole, the height of the limit screw 111 protruding from the fixed platform can be set.

[0090] The above settings can improve the versatility of the imager. Adjusting the height of the limit screw 111 can ensure that the pressure plate assembly 100 can flatten workpieces of different thicknesses and simultaneously fix the external pressure plate assembly 100.

[0091] In other embodiments, the support may also be an elastic pad or a protrusion provided on the fixed frame 110 or the worktable.

[0092] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0093] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
