Description

Technical Field

[0001] This application relates to the field of pressing technology, and more specifically, to a pressing device. Background Technology

[0002] Pressing is a technique that uses external force to tightly bond two workpieces together. During pressing, a drive component such as a cylinder or hydraulic cylinder typically moves the pressing head assembly towards the workpiece, bringing the pressing head assembly into contact with it. This allows the force exerted by the drive component on the pressing head assembly to be transmitted to the workpiece, resulting in a tight bond between the workpieces. However, when the pressing head assembly contacts the workpiece, excessive force may cause damage, thus requiring improvement. Utility Model Content

[0003] In view of this, this application provides a pressing device for pressing workpieces and reducing the probability of workpiece damage caused by the pressing head assembly.

[0004] Embodiments of this application provide a pressing device, including a support assembly, a pressure head assembly, a drive assembly, and a control assembly. The support assembly is configured to support a workpiece to be pressed; the pressure head assembly includes a connector, a pressure sensing element, and an abutment element, the pressure sensing element being connected to the abutment element and the connector; the drive assembly is disposed on the support assembly and connected to the connector, the drive assembly being configured to drive the connector to move so that the abutment element presses against the workpiece located on the support assembly; the control assembly is electrically connected to the pressure sensing element and the drive assembly. When the magnitude of the force measured by the pressure sensing element reaches a set pressure threshold, the control assembly controls the drive assembly to stop operating or controls the drive assembly to move the connector away from the support assembly.

[0005] After the workpiece to be pressed is placed on the carrier assembly, the drive assembly drives the connector to move toward the workpiece, so that the abutment comes close to the workpiece. When the abutment contacts the workpiece, an interaction force is generated between the workpiece and the abutment. The force of the abutment on the workpiece causes the workpiece to be pressed. The reverse force of the workpiece on the abutment is transmitted to the pressure detection device and measured by the pressure detection device. When the force measured by the pressure detection device reaches the pressure threshold, the control assembly controls the drive assembly to stop running or controls the drive assembly to move the connector away from the carrier assembly, so as to reduce the possibility of the force of the abutment on the workpiece further increasing, thereby reducing the probability of workpiece damage.

[0006] In some embodiments of this application, the pressure head assembly further includes a first buffer member, which connects the pressure detection member and the abutment member, and is configured to provide a buffering effect to the connector member as the connector member moves relative to the abutment member.

[0007] The first buffer can provide a buffering effect to the connecting part after the abutting part comes into contact with the workpiece, which can reduce the magnitude of the impact force of the connecting part on the abutting part, thereby reducing the possibility of the abutting part impacting the workpiece and thus reducing the risk of the workpiece being damaged by impact.

[0008] In some embodiments of this application, the abutment is provided with a sliding portion, the connector is provided with a guide portion, the sliding portion and the guide portion are slidably connected, and the connector is configured to drive the abutment to move closer to the workpiece and away from the workpiece.

[0009] After the abutment contacts the workpiece, as the connector continues to move toward the workpiece, the sliding part and the guide part slide together, which can improve the stability of the connector sliding relative to the abutment, thereby improving the stability of the direction of the force exerted by the connector on the abutment, and thus improving the stability of the workpiece under force.

[0010] In some embodiments of this application, the carrier component includes a carrier and a support. The carrier is configured to carry a workpiece, the support is disposed on the carrier, the drive component is disposed on the support, the connector is slidably connected to the support, and the support is configured to guide the connector toward and away from the carrier.

[0011] The sliding connection between the connector and the support can improve the stability of the movement of the abutment driven by the connector, thereby improving the stability of the abutment's movement trajectory and improving the accuracy of the abutment's position pressing against the workpiece.

[0012] In some embodiments of this application, the connector is provided with a second buffer, which is configured to contact the support as the connector moves toward the workpiece to provide a cushioning effect to the connector.

[0013] The second buffer can provide a buffering effect to the connector, thereby reducing the impact force of the connector on the abutment after the abutment comes into contact with the workpiece, so as to reduce the possibility of the abutment impacting the workpiece, thereby reducing the risk of the workpiece being damaged by impact, and reducing the possibility of damage to the connector or support.

[0014] In some embodiments of this application, the abutment includes a mounting base and an elastic pressure head. The mounting base is connected to a pressure detection element, and the elastic pressure head is connected to the mounting base. The elastic pressure head has an abutment surface configured to contact the workpiece.

[0015] During the process of the connecting part moving the abutting part toward the workpiece, when the abutting surface comes into contact with the workpiece, the elastic pressure head can undergo elastic deformation, which makes the elastic pressure head produce a buffering effect, thereby reducing the probability of workpiece damage.

[0016] In some embodiments of this application, the mounting base is provided with a mounting groove, the inner peripheral wall of the mounting groove is provided with a connecting groove, the elastic pressure head includes an abutting part and a connecting part, the connecting part is provided on the abutting part, the abutting part is provided with an abutting surface, the abutting part is embedded in the mounting groove and the connecting part is embedded in the connecting groove.

[0017] When installing the flexible pressure head, the abutment part can be inserted into the mounting groove, and the connecting part can be embedded into the connecting groove, so that the abutment part and the mounting base are stably connected. Through the cooperation between the connecting part and the connecting groove, the flexible pressure head and the mounting base can be detachably connected, making it easy to replace the flexible pressure head as needed.

[0018] In some embodiments of this application, the elastic pressure head is provided with an exhaust hole, which extends through the contact surface and is connected to the outside of the elastic pressure head.

[0019] After the contact surface comes into contact with the workpiece, the gas between the contact surface and the workpiece can be discharged through the exhaust hole, so that the contact surface can fully contact the workpiece, so that the elastic pressure head can fully press the workpiece, which is beneficial to improving the flatness of the workpiece after pressing.

[0020] In some embodiments of this application, the carrier component includes a carrier, a heating element, and a temperature detection element. The heating element is disposed on the carrier and configured to heat the carrier. The carrier is configured to carry the workpiece and transfer heat to the workpiece. The temperature detection element is configured to detect the temperature of the carrier. The temperature detection element and the heating element are electrically connected to a control component. When the temperature measured by the temperature detection element reaches a set temperature threshold, the control component controls the heating element to stop heating.

[0021] The heat generated by the heating element can be transferred to the workpiece through the carrier, thereby melting the adhesive used to bond the workpieces together, so that the workpieces can be fully bonded together.

[0022] In some embodiments of this application, the pressing device further includes a fixing component, which is disposed on the support component and configured to fix the workpiece.

[0023] The fixing component is used to fix the workpiece relative to the carrier component, thereby improving the stability of the workpiece fixed relative to the carrier component and reducing the possibility of misalignment between workpieces due to workpiece displacement during the pressing process.

Detailed Implementation

[0032] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0034] The terms “first,” “second,” “third,” etc., used in this article are for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] Embodiments of this application provide a pressing device, including a support assembly, a pressure head assembly, a drive assembly, and a control assembly. The support assembly is configured to support a workpiece to be pressed; the pressure head assembly includes a connector, a pressure sensing element, and an abutment element, the pressure sensing element being connected to the abutment element and the connector; the drive assembly is disposed on the support assembly and connected to the connector, the drive assembly being configured to drive the connector to move so that the abutment element presses against the workpiece located on the support assembly; the control assembly is electrically connected to the pressure sensing element and the drive assembly. When the magnitude of the force measured by the pressure sensing element reaches a set pressure threshold, the control assembly controls the drive assembly to stop operating or controls the drive assembly to move the connector away from the support assembly.

[0036] After the workpiece to be pressed is placed on the carrier assembly, the drive assembly drives the connector to move toward the workpiece, so that the abutment comes close to the workpiece. When the abutment contacts the workpiece, an interaction force is generated between the workpiece and the abutment. The force of the abutment on the workpiece causes the workpiece to be pressed. The reverse force of the workpiece on the abutment is transmitted to the pressure detection device and measured by the pressure detection device. When the force measured by the pressure detection device reaches the pressure threshold, the control assembly controls the drive assembly to stop running or controls the drive assembly to move the connector away from the carrier assembly, so as to reduce the possibility of the force of the abutment on the workpiece further increasing, thereby reducing the probability of workpiece damage.

[0037] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0038] Reference Figure 1 One embodiment of this application provides a pressing device 1000, including a support assembly 100, a pressing head assembly 200, a drive assembly 300, and a control assembly 400. The support assembly 100 is configured to support a workpiece (not shown) to be pressed, and the pressing head assembly 200 is configured to contact the workpiece under the drive of the drive assembly 300 to apply a pressure to the workpiece to press it.

[0039] In some embodiments, the support assembly 100 includes a support member 11 and a support member 12. The support member 11 is configured to support a workpiece, and the support member 12 is disposed on the support member 11. In some embodiments, the support member 11 is plate-shaped, and the support member 12 includes a support rod 121 and a support plate 122. One end of the support rod 121 is fixedly connected to the support member 11, and the other end extends away from the support member 11 along a first direction Z. The support plate 122 is fixedly connected to the end of the support rod 121 away from the support member 11. In some embodiments, the first direction Z is parallel to the thickness direction of the support member 11. In some embodiments, the thickness direction of the support member 11 is parallel to the direction of gravity. In other embodiments, the thickness direction of the support member 11 may also be parallel to the horizontal direction or intersect with the horizontal direction.

[0040] Reference Figure 1 and Figure 2 In some embodiments, the pressure head assembly 200 is disposed between the support plate 122 and the carrier member 11. In some embodiments, the pressure head assembly 200 includes a connector 21, a pressure detection element 22, and an abutment element 23, the pressure detection element 22 being connected to the abutment element 23 and the connector 21; a drive assembly 300 is disposed on the carrier assembly 100 and connected to the connector 21, the drive assembly 300 being configured to drive the connector 21 to move so that the abutment element 23 presses against a workpiece located on the carrier assembly 100. A control assembly 400 is electrically connected to the pressure detection element 22 and the drive assembly 300.

[0041] In some embodiments, the drive assembly 300 is a cylinder, with its cylinder body fixedly connected to the support plate 122, and its piston rod connected to the connector 21. The control assembly 400 is a PLC (Programmable Logic Controller), located on the support plate 122. The pressure detection element 22 is a pressure sensor. It is understood that the pressure detection element 22 and the solenoid valve used to control the drive assembly 300 are both electrically connected to the control assembly 400. In other embodiments, the drive assembly 300 may also be a hydraulic cylinder, an electric actuator, or other structural component capable of driving the connector 21 to move. In other embodiments, the control assembly 400 may also be a microcontroller or other structural component with functions of receiving signals, processing signals, and outputting control signals.

[0042] After the workpiece to be pressed is placed on the carrier 11, the drive assembly 300 drives the connector 21 to move toward the workpiece, causing the abutment 23 to approach the workpiece. When the abutment 23 contacts the workpiece, an interaction force is generated between the workpiece and the abutment 23. The force exerted by the abutment 23 on the workpiece causes the workpiece to be pressed. The reverse force exerted by the workpiece on the abutment 23 is transmitted to the pressure detection element 22 and detected by the pressure detection element 22. When the force detected by the pressure detection element 22 reaches the pressure threshold, the control assembly 400 controls the drive assembly 300 to stop operating, thereby reducing the possibility of the force exerted by the abutment 23 on the workpiece further increasing, and thus reducing the probability of workpiece damage. The time during which the control assembly 400 stops the drive assembly 300 when the force detected by the pressure detection element 22 reaches the pressure threshold can be understood as the pressure holding time, which can be preset within the control assembly 400.

[0043] In other embodiments, when the force measured by the pressure detection element 22 reaches the pressure threshold, the connecting element 21 can be moved away from the bearing element 100 by controlling the drive component 300, so as to reduce the possibility that the force of the abutment element 23 on the workpiece will further increase, thereby reducing the probability of workpiece damage.

[0044] In some embodiments, the abutment 23 has a sliding portion 231, and the connector 21 has a guide portion 211. The sliding portion 231 and the guide portion 211 are slidably connected, and the connector 21 is configured to drive the abutment 23 towards and away from the workpiece. In some embodiments, the connector 21 includes a connecting plate 212, and the guide portion 211 includes a guide hole that extends through the connecting plate 212 in a first direction Z. The sliding portion 231 includes a sliding rod 2311 and a limiting portion 2312 fixedly connected to one end of the sliding rod 2311. The end of the sliding rod 2311 away from the limiting portion 2312 is inserted into the guide hole and connected to the abutment 23, such that the limiting portion 2312 is located on the side of the connecting plate 212 away from the abutment 23, and the sliding rod 2311 is slidably engaged with the guide hole. In some embodiments, the limiting portion 2312 is a nut, and the limiting portion 2312 is threadedly connected to the sliding rod 2311.

[0045] During the process of the drive assembly 300 driving the connecting plate 212 to move towards the workpiece located on the support member 11 along the first direction Z, after the abutment member 23 contacts the workpiece, the connecting member 21 can continue to move towards the workpiece. When the connecting plate 212 abuts against the abutment member 23, the drive assembly 300 transmits the driving force to the abutment member 23 through the connecting plate 212, so that the abutment member 23 generates a low pressure on the workpiece to press it. When the drive assembly 300 drives the connecting plate 212 away from the workpiece along the first direction Z, after the connecting plate 212 abuts against the limiting part 2312, the connecting plate 212 can drive the limiting part 2312 and the sliding rod 2311 to move synchronously, thereby causing the abutment member 23 to move away from the workpiece.

[0046] In some embodiments, the pressure head assembly 200 further includes a first buffer 24, which connects the pressure detection element 22 and the abutment 23. The first buffer 24 is configured to provide a buffering effect to the connector 21 when the connector 21 moves relative to the abutment 23. In some embodiments, the first buffer 24 is disposed between the abutment 23 and the connecting plate 212. The first buffer 24 includes a buffer plate 241 and a buffer spring 242. The buffer plate 241 is located on the side of the buffer spring 242 away from the abutment 23, and the buffer plate 241 and the buffer spring 242 are slidably sleeved on the sliding rod 2311. The pressure detection element 22 is mounted on the surface of the buffer plate 241 facing the connecting plate 212. After the abutment 23 contacts the workpiece, as the connecting plate 212 moves closer to the abutment 23, it may contact the pressure detection element 22 and cause the buffer plate 241 to move closer to the abutment 23, thus compressing the buffer spring 242. This allows the connecting plate 212 to abut against the abutment 23 in sequence, passing through the pressure detection element 22, the buffer plate 241, and the buffer spring 242, thereby applying a pressure to the abutment 23. When the buffer spring 242 is compressed, it provides a cushioning effect to the connecting plate 212.

[0047] In some embodiments, the two ends of the buffer spring 242 may be fixedly connected to the buffer plate 241 and the abutment member 23, respectively. In some embodiments, the buffer plate 241 may be omitted, and the two ends of the buffer spring 242 may be fixedly connected to the pressure detection member 22 and the abutment member 23, respectively. In some embodiments, the first buffer member 24 may also be a hydraulic buffer, a pneumatic buffer, a structural member made of rubber, or other structural members capable of providing a buffering effect.

[0048] In some other embodiments, the first buffer 24 may be omitted, and the pressure detection element 22 may be disposed on the abutment 23, so that when the connecting plate 212 moves toward the workpiece, after the abutment 23 contacts the workpiece, the connecting plate 212 can contact the pressure detection element 22, so that the connecting plate 212 applies a force to the abutment 23 through the pressure detection element 22.

[0049] In some embodiments, the abutment member 23 includes a mounting base 232 and an elastic pressure head 233. The mounting base 232 is connected to the pressure detection member 22, and the elastic pressure head 233 is connected to the mounting base 232. The elastic pressure head 233 has an abutment surface 2331 configured to contact the workpiece. It is understood that in some embodiments, the mounting base 232 is connected to the pressure detection member 22 via a first buffer member 24.

[0050] During the process of the connector 21 driving the abutment 23 to move toward the workpiece, when the abutment surface 2331 comes into contact with the workpiece, the elastic pressure head 233 can undergo elastic deformation, which makes the elastic pressure head 233 produce a buffering effect, thereby reducing the probability of workpiece damage; at the same time, after the elastic pressure head 233 undergoes elastic deformation, it can fully fit the elastic pressure head 233 with the workpiece, which is beneficial to improving the pressing effect.

[0051] Reference Figure 3 In some embodiments, the mounting base 232 is provided with a mounting groove 2321, and the inner peripheral wall of the mounting groove 2321 is provided with a connecting groove 2322. The elastic pressure head 233 includes an abutment portion 2332 and a connecting portion 2333. The connecting portion 2333 is disposed on the abutment portion 2332, and the abutment portion 2332 is provided with an abutment surface 2331. The abutment portion 2332 is embedded in the mounting groove 2321, and the connecting portion 2333 is embedded in the connecting groove 2322. In some embodiments, the connecting portion 2333 is disposed on the peripheral wall of the abutment portion 2332, and the connecting portion 2333 and the abutment portion 2332 are integrally formed. It is understood that the abutment surface 2331 is disposed towards the support member 11 and protrudes to the outside of the mounting groove 2321. When installing the elastic pressure head 233, the abutment part 2332 can be embedded into the mounting groove 2321, and the connecting part 2333 can be embedded into the connecting groove 2322, so that the abutment part 2332 and the mounting base 232 are stably connected. Through the cooperation of the connecting part 2333 and the connecting groove 2322, the elastic pressure head 233 and the mounting base 232 can be detachably connected, making it easy to replace the elastic pressure head 233 as needed.

[0052] In some embodiments, the elastic pressure head 233 is provided with a vent 2334, which penetrates the contact surface 2331. The vent 2334 is formed through the elastic pressure head 233 along the first direction Z and communicates with the outside of the elastic pressure head 233. The mounting base 232 is formed through the contact hole 2323 along the first direction Z, and the contact hole 2323 is aligned with the vent 2334. After the contact surface 2331 contacts the workpiece, the gas between the contact surface 2331 and the workpiece can be discharged through the vent 2334, thereby allowing the contact surface 2331 to fully contact the workpiece, so that the elastic pressure head 2333 can fully press against the workpiece, which is beneficial to improving the flatness of the pressed workpiece. In other embodiments, the vent 2334 may also be formed along a direction intersecting the first direction Z. In other embodiments, an extension hole may be formed along a direction intersecting the first direction Z, and the vent 2334 may communicate with the extension hole, so that the vent 2334 communicates with the outside of the elastic pressure head 233.

[0053] Reference Figure 1In some embodiments, the connector 21 further includes a guide sleeve 213, which is connected to the connecting plate 212 and is sleeved on the support rod 121 and slides in cooperation with the support rod 121, so that the connecting plate 212 and the support member 12 slide in a first direction Z, which can improve the stability of the connecting plate 212 moving under the drive of the drive assembly 300.

[0054] In some embodiments, the connector 21 is provided with a second buffer 214, which is configured to contact the support 12 when the connector 21 moves toward the workpiece to provide a cushioning effect. In some embodiments, the support plate 122 is provided with a clearance hole 1221 extending along a first direction Z. The connector 21 also includes a connecting frame 215, one end of which is connected to the connecting plate 212, and the other end of the connector 21 passes through the clearance hole 1221 and extends to the side of the support plate 122 opposite to the connecting plate 212. The second buffer 214 is located on the side of the support plate 122 opposite to the connecting plate 212, and the second buffer 214 is connected to the connecting frame 215.

[0055] As the connecting plate 212 moves toward the workpiece, the connecting member 21 drives the second buffer member 214 to move. When the second buffer member 214 abuts against the support plate 122, it undergoes elastic deformation to provide a buffering effect to the connecting frame 215. In some embodiments, the second buffer member 214 is a hydraulic buffer. In other embodiments, the second buffer member 214 may be a pneumatic buffer, a spring, a structural member made of rubber, or other structural members capable of providing a buffering effect.

[0056] Reference Figure 4 In some embodiments, the support assembly 100 further includes a heating element 13 and a temperature detection element 14. The heating element 13 is disposed on the support assembly 11 and configured to heat the support assembly 11. The support assembly 11 is configured to carry the workpiece and transfer heat to the workpiece. The temperature detection element 14 is configured to detect the temperature of the support assembly 11. The temperature detection element 14 and the heating element 13 are electrically connected to the control assembly 400. When the temperature measured by the temperature detection element 14 reaches a set temperature threshold, the control assembly 400 controls the heating element 13 to stop heating. The heat generated by the heating element 13 can be transferred to the workpiece through the support assembly 11, thereby melting the adhesive used for bonding between the workpieces to facilitate full adhesion between the workpieces.

[0057] For ease of description, we define a second direction X and a third direction Y, where the second direction X, the third direction Y, and the first direction Z are all perpendicular to each other.

[0058] In some embodiments, the support member 11 has a mounting hole 111 on one side wall along the second direction X. The mounting hole 111 is located along the second direction X. The heating element 13 is a heating rod, which is inserted into the mounting hole 111. Installing the heating element 13 in the mounting hole 111 increases the contact area between the heating element 13 and the support member 11, thereby improving the efficiency of the heating element 13 in heating the support member 11. In other embodiments, the mounting hole 111 may also be located on one side wall of the support member 11 along the third direction Y or at other locations, as long as the heat from the heating element 13 can be transferred to the support member 11.

[0059] In some embodiments, a detection hole 112 is formed on one side wall of the carrier 11 along the third direction Y. A temperature detection element 14, a temperature sensor, is inserted into the detection hole 112. Installing the temperature detection element 14 within the detection hole 112 increases the contact area between the temperature detection element 14 and the carrier 11, thereby improving the detection accuracy of the temperature detection element 14. In other embodiments, the detection hole 112 may also be formed on one side wall of the carrier 11 along the second direction X or at other locations, as long as the temperature detection element 14 can detect the temperature of the carrier 11.

[0060] In some embodiments, the pressing device 1000 further includes a fixing component 500, which is disposed on the support component 100 and configured to fix the workpiece.

[0061] Reference Figure 4 and Figure 5 In some embodiments, the fixing assembly 500 includes two first clamping members 51 disposed opposite each other along a second direction X. Each first clamping member 51 includes a first clamping rod 511, a first connecting rod 512, a first slide block 513, and a drive screw 514. The first clamping rod 511 is connected to the first connecting rod 512, and the first connecting rod 512 is connected to the first slide block 513. The first slide block 513 is slidably connected to the carrier member 11 along the second direction X. The drive screw 514 is rotatably connected to the carrier member 11 and slidably connected to the first slide block 513. After placing the workpiece between the two first clamping rods 511, rotating the drive screw 514 moves the first slide block 513, causing the first clamping rods 511 to move closer to the workpiece, so that the first clamping rods 511 contact and press against the workpiece, thereby achieving the effect of fixing the workpiece.

[0062] Reference Figure 1 and Figure 5In some embodiments, the carrier assembly 100 further includes a fixing seat 15, which is located on the side of the carrier 11 away from the pressure head assembly 200. The carrier assembly 100 is fixedly connected to the fixing seat 15, and the drive screw 514 is rotatably connected to the fixing seat 15 so that the drive screw 514 is connected to the carrier 11.

[0063] In some other embodiments, the first connecting rod 512 and the first slide block 513 may be omitted, allowing the first clamping rod 511 to slide and connect to the carrier 11 and be threadedly connected to the drive screw 514.

[0064] Reference Figure 4 and Figure 6 In some embodiments, the fixing assembly 500 further includes two second clamping members 52 disposed opposite each other along a third direction Y. Each second clamping member 52 includes a second clamping rod 521, a second connecting rod 522, a second slide block 523, an abutment screw 524, and a base 525. The base 525 is fixedly connected to the side of the carrier 11 facing the fixing seat 15. The second clamping rod 521 is connected to the second connecting rod 522, and the second connecting rod 522 is connected to the second slide block 523. The second slide block 523 is slidably connected to the base 525 along the third direction Y. The abutment screw 524 is disposed on the side of the second clamping rod 521 opposite to the other second clamping member 52, and the abutment screw 524 is threadedly connected to the base 525. Rotating the abutment screw 524 allows it to abut against the second connecting rod 522, thereby pushing the second connecting rod 522 along the third direction Y. After the workpiece is placed between the two second clamping rods 521, the abutment screw 524 is rotated, which pushes the second connecting rod 522 so that the second clamping rod 521 contacts and presses against the workpiece to fix it.

[0065] In other embodiments, the second connecting rod 522, the second slide block 523, and the base 525 may be omitted, allowing the second clamping rod 521 to be slidably connected to the carrier 11, and the abutting screw 524 to be threadedly connected to the carrier 11. By having the abutting screw 524 push the second clamping rod 521 along the third direction Y, the second clamping rod 521 is pressed against the workpiece.

[0066] In some embodiments, the pressing device 1000 operates as follows:

[0067] After the workpiece to be pressed is placed on the carrier 11 and fixed by the fixing component 500, the control component 400 controls the drive component 300 to operate. The drive component 300 drives the connecting component 21 to move towards the workpiece. When the abutting component 23 contacts the workpiece, the driving force of the drive component 300 acting on the connecting component 21 is transmitted to the abutting component 23 through the pressure detection component 22, causing the abutting component 23 to press against the workpiece, thus pressing the workpiece together. During the pressing process, when the force measured by the pressure detection component 22 reaches the set pressure threshold, the control component 400 stops the drive component 300, allowing the abutting component 23 to continue to maintain contact with the workpiece for pressure holding. After pressure holding is completed, the control component 400 controls the drive component 300 to move the connecting component 21 away from the carrier 11, so that the abutting component 23 separates from the workpiece. By setting the pressure detection component 22 and the control component 400, the risk of damage to the workpiece due to excessive force during the pressing process can be reduced.
