Description

Technical Field

[0001] This application relates to the field of automation equipment technology, and more specifically, to a pressure-holding device. Background Technology

[0002] During product assembly, it is sometimes necessary to use a pressure head to continuously press the components on the product for a period of time in order to maintain pressure on the components and thus improve the stability of the component connection.

[0003] To improve the pressure holding effect, the pressure heads used to press against materials of different specifications are generally different. When multiple different materials on a product need to be pressurized, the product needs to be clamped onto multiple pressure holding devices with corresponding different pressure heads in sequence, resulting in a large number of clamping operations and thus low efficiency of the pressure holding operation. Utility Model Content

[0004] In view of this, this application provides a pressure holding device that can reduce the number of product clamping operations, thereby improving the efficiency of pressure holding operations.

[0005] One embodiment of this application provides a pressure-holding device, including a support mechanism, multiple pressure-holding mechanisms, a load-bearing mechanism, and a drive mechanism. The multiple pressure-holding mechanisms are arranged sequentially and are all disposed on the support mechanism, and are configured to respectively press against multiple components of a product. The arrangement direction of the multiple pressure-holding mechanisms is a first direction. The load-bearing mechanism is connected to the support mechanism and configured to mount the product. The drive mechanism connects the load-bearing mechanism and the support mechanism, and is configured to drive the load-bearing mechanism to move along the first direction.

[0006] In the above embodiments, when performing a pressure-holding operation on the product, the product is first installed onto the carrier mechanism. Then, the drive mechanism drives the carrier mechanism to move along a first direction, sequentially moving the product to the positions of multiple pressure-holding mechanisms. When the product moves to the position of any pressure-holding mechanism, the corresponding pressure-holding mechanism presses against the corresponding component on the product to perform a pressure-holding operation on the corresponding component. When using this pressure-holding device to perform pressure-holding operations on multiple components on a product, after the product moves from one pressure-holding mechanism to another, there is no need to re-clamp the product, which reduces the number of times the product can be clamped and improves the efficiency of performing pressure-holding operations on multiple components on a product.

[0007] In some embodiments of this application, the supporting mechanism includes a support member, an angle adjustment assembly, and a linear adjustment assembly. The support member is configured to mount a product. The angle adjustment assembly is connected to the support member and configured to drive the support member to rotate. The linear adjustment assembly is connected to the drive mechanism and the angle adjustment assembly, and is configured to drive the angle adjustment assembly to move along a second direction intersecting the first direction. The pressure holding device further includes a first control member and a position detection member. The position detection member is configured to detect the position of the material, and the angle adjustment assembly, the linear adjustment assembly, and the position detection member are all electrically connected to the first control member.

[0008] In the above embodiments, the position detection component can detect the position of the material on the product. The first control component controls the angle adjustment component and the linear adjustment component according to the detection data of the position detection component, so that the angle adjustment component drives the carrier to rotate and the linear adjustment component drives the angle adjustment component and the carrier to move along the second direction, so that the material on the product on the carrier is aligned with the corresponding pressure holding mechanism along the first direction. This facilitates the quick and accurate alignment of the material on the product with the corresponding pressure holding mechanism under the action of the driving mechanism, which is beneficial to improving the accuracy of the pressure holding mechanism in pressing the material.

[0009] In some embodiments of this application, the pressure-holding mechanism includes a pressure head assembly, a pressure-holding drive assembly, a pressure detection element, and a second control element. The pressure head assembly is configured to abut against a workpiece. The pressure-holding drive assembly is disposed on a support mechanism and configured to drive the pressure head assembly toward and away from the support mechanism along a third direction. The pressure head assembly is movable relative to the pressure-holding drive assembly along a third direction, which intersects with a first direction. The pressure detection element is configured to detect the magnitude of the force exerted by the pressure-holding drive assembly on the pressure head assembly along the third direction and toward the support mechanism. Both the pressure detection element and the pressure-holding drive assembly are electrically connected to the second control element. When the pressure-holding drive assembly drives the pressure head assembly toward the support mechanism and the force measured by the pressure detection element is greater than a predetermined threshold, the pressure-holding drive assembly drives the pressure head assembly away from the support mechanism.

[0010] In the above embodiments, during the process of the pressure holding drive assembly driving the pressure head assembly to approach the support mechanism in a third direction, after the pressure head assembly comes into contact with the material of the product on the support mechanism, the pressure of the pressure head assembly on the material gradually increases to a predetermined level to maintain pressure on the corresponding material; if the force exerted by the pressure head assembly on the material exceeds a predetermined threshold due to a malfunction, the pressure holding drive assembly drives the pressure head assembly to move away from the support mechanism, so that the pressure head assembly separates from the material, thereby reducing the probability of damage to the material.

[0011] In some embodiments of this application, the pressure-holding drive assembly includes a pressure-holding drive member and a counterweight. The pressure-holding drive member is disposed on a support mechanism. The counterweight is connected to the pressure-holding drive member, and the pressure-holding drive member is configured to drive the counterweight away from the support mechanism in a third direction. The counterweight is movable relative to the pressure-holding drive member in a third direction and is configured to abut against the pressure head assembly under gravity, so that the pressure head assembly abuts against the material on the support mechanism. A pressure detection member is configured to detect the magnitude of the force between the counterweight and the pressure head assembly. The pressure-holding drive member or the counterweight is configured to drive the pressure head assembly away from the support mechanism in a third direction.

[0012] In the above embodiments, during the process of the pressure-holding drive driving the counterweight towards the bearing mechanism, the counterweight abuts against the pressure head assembly under the action of gravity, so that the pressure head assembly is subjected to the pressure of the counterweight to maintain pressure on the material. When the pressure-holding drive drives the counterweight away from the bearing mechanism, the pressure-holding drive or the counterweight drives the pressure head assembly away from the bearing mechanism, so that the pressure head assembly separates from the material. The counterweight presses against the material through the pressure head assembly, and by controlling the weight of the counterweight, the pressure on the material can be precisely controlled.

[0013] In some embodiments of this application, the counterweight includes a counterweight frame and a plurality of counterweight blocks. The counterweight blocks are detachably connected to the counterweight frame, and the plurality of counterweight blocks are detachably connected to each other.

[0014] In the above embodiments, the counterweight blocks are detachably connected to the counterweight frame and to each other. By adjusting the number of counterweight blocks installed, the pressure on the pressure head assembly can be adjusted to adapt to different materials.

[0015] In some embodiments of this application, the pressure head assembly includes a pressure holding head, which has an abutment portion, and the pressure holding drive assembly has a receiving portion. Along the direction in which the pressure holding head moves toward the bearing mechanism, the receiving portion is located in front of the abutment portion and is configured to abut against the abutment portion.

[0016] In the above embodiments, when the pressure holding drive assembly drives the receiving part to move away from the bearing mechanism, after the receiving part abuts the abutting part, the receiving part can drive the abutting part and the pressure holding head to move synchronously, thereby enabling the pressure holding head to move away from the bearing mechanism so as to separate the pressure holding head from the material.

[0017] In some embodiments of this application, the pressure head assembly includes a holding pressure head, a connector, and an elastic member. The holding pressure head is connected to and movable relative to the holding pressure drive assembly in a third direction, and is configured to abut against the workpiece. The connector is configured to connect to the holding pressure drive assembly so that the holding pressure drive assembly drives the connector to move toward a supporting mechanism in a third direction. The elastic member connects the holding pressure head and the connector, and is configured to provide cushioning to the connector. A pressure sensing element is configured to detect the magnitude of the force between the connector and the holding pressure drive assembly.

[0018] In the above embodiments, after the pressure-holding drive assembly is connected to the connector, the pressure-holding drive assembly drives the connector to move toward the bearing mechanism in a third direction. The connector, through an elastic element, drives the pressure-holding head to move toward the bearing mechanism to press against the workpiece. After the connector is driven by the pressure-holding drive assembly, the elastic element undergoes elastic deformation to buffer the connector, which helps to reduce the magnitude of the impact force of the connector on the pressure-holding head, thereby reducing the impact force of the pressure-holding head on the workpiece and reducing the possibility of damage to the workpiece.

[0019] In some embodiments of this application, a guide is connected between the connector and the pressure holding head, and the guide is configured to guide the connector to move relative to the pressure holding head in a third direction.

[0020] In the above embodiments, the guide causes the connector to move relative to the pressure holding head in a third direction, so that the direction of the force exerted by the connector on the elastic element is the same as the direction of the elastic force of the elastic element and the direction of movement of the pressure holding head, thereby helping to reduce the probability of the elastic element bending and deforming.

[0021] In some embodiments of this application, the pressure-holding head and the connector are configured to abut against both ends of the elastic member, and the pressure-holding head and the connector are provided with connecting grooves or connecting protrusions. One end of the elastic member is configured to be sleeved on the corresponding connecting protrusion or inserted into the corresponding connecting groove.

[0022] In the above embodiments, one end of the elastic element is sleeved on the connecting protrusion or inserted into the connecting groove, which facilitates the installation or removal of the elastic element and thus facilitates its replacement. After the end of the elastic element is inserted into the connecting groove or sleeved on the connecting protrusion, the inner wall of the connecting groove or the peripheral wall of the connecting protrusion has a restraining effect on the elastic element, which helps to reduce the possibility of the elastic element shifting relative to the connecting element or the pressure holding head after being subjected to force, thereby improving the stability of the connection of the elastic element.

[0023] In some embodiments of this application, the support mechanism is provided with a buffer element, which is configured to connect to the pressure holding drive assembly and provide a buffering effect to the pressure holding drive assembly.

[0024] In the above embodiments, during the process of the pressure holding drive assembly driving the pressure head assembly to move toward the bearing mechanism, the buffer has a buffering effect on the pressure holding drive assembly, which helps to reduce the magnitude of the impact force of the pressure holding drive assembly on the pressure head assembly, thereby helping to reduce the impact force of the pressure head assembly on the material and reducing the possibility of damage to the material.

[0036] This application provides a pressure-holding device for applying pressure to multiple components on a product. The pressure-holding device includes a support mechanism, multiple pressure-holding mechanisms, a load-bearing mechanism, and a drive mechanism. The multiple pressure-holding mechanisms are arranged sequentially and disposed on the support mechanism, and are configured to press against the multiple components of the product.

The drive mechanism connects the load-bearing mechanism and the support mechanism, and is configured to drive the load-bearing mechanism to move along the first direction.

[0037] When performing a pressure-holding operation on a product, the product is first installed onto a supporting mechanism. Then, a drive mechanism moves the supporting mechanism along a first direction, sequentially moving the product to the positions of multiple pressure-holding mechanisms. Once the product reaches any of these mechanisms, the corresponding pressure-holding mechanism presses against the corresponding component on the product to perform a pressure-holding operation. When using this pressure-holding device to perform pressure-holding operations on multiple components of a product, the product does not need to be re-clamped after moving from one pressure-holding mechanism to another, reducing the number of clamping operations and improving the efficiency of pressure-holding operations on multiple components of a product.

Then, the drive mechanism 4 drives the support mechanism 3 to move along the first direction, which can sequentially move the product to the positions of multiple pressure-holding mechanisms 2.

[0042] In some embodiments, the support mechanism 1 includes a support frame 11 and a support base (not shown in the figure), the support frame 11 being gantry-shaped. Both columns of the support frame 11 are fixedly connected to the support base. It is understood that the drive mechanism 4 is disposed on the support base, and the pressure-holding mechanism 2 is disposed on the crossbar of the support frame 11. In some embodiments, multiple sets of the drive mechanism 4 and the corresponding multiple pressure-holding mechanisms 2 are arranged along the length direction of the crossbar of the support frame 11. It is understood that the multiple sets of drive mechanisms 4 and multiple sets of pressure-holding mechanisms 2 are sequentially spaced along the length direction of the crossbar of the support frame 11 to simultaneously perform pressure-holding operations on materials on multiple products.

[0043] In some embodiments, the support base may be omitted, and the support frame 11 is disposed on the ground, with the drive mechanism 4 disposed on the support frame 11 or the ground. In other embodiments, the support frame 11 may also be of other shapes, as long as it can accommodate multiple pressure-holding mechanisms 2.

In other embodiments, the first control element can be a microcontroller. In still other embodiments, the first control element can also be the control device for the position detection element 5, i.e., the first control element and the control device for the position detection element 5 are integrated into one structure.

[0047] Reference Figure 1 In some embodiments, the support mechanism 3 includes a support member 31, an angle adjustment assembly 32, and a linear adjustment assembly 33. The support member 31 is configured to mount the product. The angle adjustment assembly 32 is connected to the support member 31 and configured to drive the support member 31 to rotate. The linear adjustment assembly 33 is connected to the drive mechanism 4 and the angle adjustment assembly 32, and is configured to drive the angle adjustment assembly 32 to move along a second direction Y, which intersects with the first direction X. The angle adjustment assembly 32, the linear adjustment assembly 33, and the position detection element 5 are all electrically connected to the first control element.

[0048] The position detection component 5 can detect the position of the material on the product. The first control component controls the angle adjustment component 32 and the linear adjustment component 33 according to the detection data of the position detection component 5. The angle adjustment component 32 drives the carrier component 31 to rotate, and the linear adjustment component 33 drives the angle adjustment component 32 and the carrier component 31 to move along the second direction Y. This makes the material on the product on the carrier component 31 aligned with the corresponding pressure holding mechanism 2 along the first direction X. This facilitates the quick and accurate alignment of the material on the product with the corresponding pressure holding mechanism 2 under the action of the drive mechanism 4, which helps to improve the accuracy of the pressure holding mechanism 2 in pressing the material.

[0049] In some embodiments, the carrier 31 is a carrier plate, and the product is fixed to the carrier 31 by negative pressure adsorption. In other embodiments, the product can be fixedly connected to the carrier 31 by bolts or clamping blocks. In still other embodiments, the product is placed on the carrier 31, and the product is fixed relative to the carrier 31 by its own weight.

[0050] Reference Figure 1 and Figure 2 The linear adjustment assembly 33 includes a fixed base 331, a sliding base (not shown in the figure), and a sliding component 332. The fixed base 331 is fixedly connected to the movable base 42 of the drive mechanism 4. The sliding base is slidably connected to the fixed base 331 along the second direction Y. The sliding component 332 is connected to the fixed base 331 and configured to drive the sliding base to slide. The sliding component 332 is electrically connected to the first control element. In some embodiments, the sliding component 332 is a lead screw and nut structure driven by a motor, and the sliding base is connected to the corresponding nut. It can be understood that the motor of the sliding component 332 is electrically connected to the first control element. In other embodiments, the sliding component 332 is a linear motor or other structural components capable of driving the sliding base to slide.

[0051] In some embodiments, the angle adjustment assembly 32 includes a connecting seat 321, a rotating seat 322, and a rotating assembly 323.

In some embodiments, the rotating assembly 323 is a worm gear structure driven by a motor; that is, the motor of the rotating assembly 323 is electrically connected to the first control member.

In other embodiments, the rotating assembly 323 can also be a motor, with the output shaft of the motor connected to the rotating seat 322.

[0052] Reference Figure 1 and Figure 3In some embodiments, the pressure holding mechanism 2 includes a pressure head assembly 21, a pressure holding drive assembly 22, a pressure detection element 23, and a second control element (not shown). The pressure head assembly 21 is configured to abut against the workpiece. The pressure holding drive assembly 22 is disposed on the support mechanism 1 and configured to drive the pressure head assembly 21 toward and away from the support mechanism 3 along a third direction Z. The pressure head assembly 21 is movable relative to the pressure holding drive assembly 22 along the third direction Z, which intersects with the first direction X. The pressure detection element 23 is configured to detect the magnitude of the force exerted by the pressure holding drive assembly 22 on the pressure head assembly 21 along the third direction Z and toward the support mechanism 3. Both the pressure detection element 23 and the pressure holding drive assembly 22 are electrically connected to the second control element. When the pressure holding drive assembly 22 drives the pressure head assembly 21 toward the support mechanism 3 and the force measured by the pressure detection element 23 is greater than a predetermined threshold, the pressure holding drive assembly 22 drives the pressure head assembly 21 away from the support mechanism 3.

[0053] As the pressure holding drive assembly 22 drives the pressure head assembly 21 toward the support mechanism 3 in the Z direction, after the pressure head assembly 21 comes into contact with the material of the product on the support mechanism 3, the pressure of the pressure head assembly 21 on the material gradually increases to a predetermined level to maintain pressure on the corresponding material. If the force exerted by the pressure head assembly 21 on the material exceeds a predetermined threshold due to a malfunction, the pressure holding drive assembly 22 drives the pressure head assembly 21 to move away from the support mechanism 3, so that the pressure head assembly 21 separates from the material, thereby reducing the probability of damage to the material.

The counterweight 222 is movable relative to the pressure-holding drive member 221 along the third direction Z and is configured to abut against the pressure head assembly 21 under gravity, so that the pressure head assembly 21 abuts against the material on the support mechanism 3. The pressure detection member 23 is configured to detect the magnitude of the force between the counterweight 222 and the pressure head assembly 21. The counterweight 222 is configured to drive the pressure head assembly 21 away from the support mechanism 3 along the third direction Z.

In some embodiments, the pressure-holding drive member 221 includes a pressure-holding cylinder 2211 and a support rod 2212. The cylinder body of the pressure-holding cylinder 2211 is fixedly connected to the connecting frame 111, and the support rod 2212 is fixedly connected to the piston rod of the pressure-holding cylinder 2211. The pressure-holding cylinder 2211 is configured to drive the support rod 2212 to move along a third direction Z. It is understood that the pressure-holding cylinder 2211 is electrically connected to a second control member.

Along the direction in which the support rod 2212 moves toward the bearing mechanism 3, the support rod 2212 is located in front of the inner wall of one end of the mating groove 2223, and this inner wall is configured to abut against the support rod 2212 so that the support rod 2212 supports the counterweight frame 2221.

[0061] Reference Figure 1 and Figure 3In some embodiments, the pressure head assembly 21 includes a pressure holding head 211, which is slidably connected to the counterweight frame 2221 in the third direction Z via a slide rail. The pressure holding head 211 has an abutment portion 2111, and the pressure holding drive assembly 22 has a receiving portion 223. Along the direction in which the pressure holding head 211 moves toward the bearing mechanism 3, the receiving portion 223 is located in front of the abutment portion 2111 and is configured to abut against the abutment portion 2111.

The abutment portion 2111 is rod-shaped, fixedly connected to the pressure-holding head 211, and extends into the support groove 2224. The abutment portion 2111 abuts against the receiving portion 223, allowing the receiving portion 223 to receive the pressure-holding head 211. The pressure-holding head 2111 has a pressure head 2112 at the end along the third direction Z and near the support mechanism 3. The pressure head 2112 is configured to abut against a material.

[0063] In some embodiments, the counterweight frame 2221 is provided with a mounting block 2225, which is located on the side of the pressure-holding head 211 along the third direction Z and away from the bearing mechanism 3. The side wall of the pressure-holding head 211 facing the mounting block 2225 is a contact portion 2113. A pressure detection element 23 is disposed between the mounting block 2225 and the contact portion 2113 and is fixedly connected to the mounting block 2225.

[0064] When the pressure-holding cylinder 2211 drives the support rod 2212 to move toward the bearing mechanism 3, after the pressure head 2112 abuts against the material, the pressure-holding pressure head 211 moves relative to the counterweight frame 2221. The abutting part 2111 separates from the receiving part 223, and the contact part 2113 abuts against the pressure detection element 23, so that the counterweight frame 2221 moves relative to the connecting frame 111, so that the support rod 2212 separates from the inner end wall of the mating groove 2223, thereby allowing the weight of the counterweight block 2222 and the counterweight frame 2221 to be applied to the corresponding material through the pressure-holding pressure head 211. When the pressure-holding cylinder 2211 drives the support rod 2212 to move away from the bearing mechanism 3, the support rod 2212 abuts against the inner wall of the mating groove 2223, thereby driving the counterweight frame 2221 to move synchronously, so that the pressure detection element 23 separates from the contact part 2113, and the pressure on the pressure-holding head 211 decreases; when the receiving part 223 abuts against the contact part 2111, the pressure-holding head 211 moves away from the bearing mechanism 3 along with the counterweight frame 2221, thereby causing the pressure head 2112 to separate from the material.

[0065] In some other embodiments, the receiving part 223 may be provided on the supporting rod 2212 so that the supporting rod 2212 can drive the pressure holding head 211 away from the bearing mechanism 3, thereby enabling the pressure holding drive member 221 to drive the pressure holding head 211 away from the bearing mechanism 3.

[0066] Reference Figure 1 and Figure 4 In some embodiments, the support mechanism 1 is provided with a buffer 12, which is configured to connect to the pressure holding drive assembly 22 and provide a buffering effect to the pressure holding drive assembly 22.

[0067] During the process of the pressure holding drive assembly 22 driving the pressure head assembly 21 to move toward the bearing mechanism 3, the buffer 12 has a buffering effect on the pressure holding drive assembly 22, which helps to reduce the magnitude of the impact force of the pressure holding drive assembly 22 on the pressure head assembly 21, thereby helping to reduce the impact force of the pressure head assembly 21 on the material and reducing the possibility of damage to the material.

[0068] In some embodiments, the buffer 12 is located in front of the support rod 2212 along the direction in which the support rod 2212 moves toward the bearing mechanism 3. The buffer 12 includes a hydraulic spring, the cylinder of the buffer 12 is fixedly connected to the connector 212, and the piston rod of the buffer 12 is configured to abut against the support rod 2212. When the piston rod of the buffer 12 abuts against the support rod 2212, the hydraulic oil in the cylinder of the buffer 12 is compressed to provide a cushioning effect on the support rod 2212. In other embodiments, the buffer 12 is a coil spring or a gas spring.

[0069] Reference Figure 1 and Figure 5 In some embodiments, the pressure-holding drive assembly 22 includes a pressure-holding drive component 221, which includes a pressure-holding cylinder 2211, a support rod 2212, and a connecting rod 2213. A mounting bracket 112 is fixedly connected to the support frame 11 of the support mechanism 1. The cylinder body of the pressure-holding cylinder 2211 is fixedly connected to the mounting bracket 112. The connecting rod 2213 is fixedly connected to the piston rod of the pressure-holding cylinder 2211. The support rod 2212 and the connecting rod 2213 are integrally formed and extend in a direction perpendicular to the third direction Z. In some embodiments, the pressure detection component 23 is fixedly connected to the piston rod of the pressure-holding cylinder 2211.

[0070] In some embodiments, the pressure head assembly 21 includes a pressure holding head 211, a connector 212, and an elastic member 213. The pressure holding head 211 is connected to the pressure holding drive assembly 22 and is movable relative to the pressure holding drive assembly 22 in the third direction Z. The pressure holding head 211 is provided with a pressure head 2112, which is configured to abut against the workpiece. The connector 212 is configured to connect to the pressure holding drive assembly 22 so that the pressure holding drive assembly 221 drives the connector 212 to move toward the support mechanism 3 in the third direction Z. The elastic member 213 connects the pressure holding head 211 and the connector 212, and is configured to provide a cushioning effect to the connector 212.

[0071] Reference Figure 5 and Figure 6 It is understood that in some embodiments, the connector 212 is located between the pressure holding head 211 and the pressure detection element 23. The pressure holding head 211 is slidably connected to the mounting bracket 112 along the third direction Z via a slide rail. The pressure holding head 211 is provided with an abutment portion 2111, which is located in front of the abutment portion 2111 along the direction in which the support rod 2212 moves toward the bearing mechanism 3. The abutment portion 2111 is rod-shaped and fixedly connected to the pressure holding head 211, and is configured to abut against the support rod 2212.

[0072] In some embodiments, the third direction Z is parallel to the direction of gravity, and the support rod 2212 is used to support the abutment portion 2111, thereby supporting the pressure-holding head 211. In other embodiments, the third direction Z may be parallel or perpendicular to the direction of gravity.

[0073] When the piston rod of the pressure-holding cylinder 2211 drives the support rod 2212 to move along the third direction Z toward the bearing mechanism 3, after the pressure head 2112 abuts against the workpiece, the pressure-holding head 211 moves relative to the mounting bracket 112, causing the abutting part 2111 to separate from the support rod 2212, and causing the pressure detection element 23 to abut against the connecting part 212. The piston rod of the pressure-holding cylinder 2211 presses against the connecting part 212 through the pressure detection element 23, causing the connecting part 212 to move toward the pressure-holding head 211. The pressure of the pressure-holding head 211 on the connecting part 212 is transmitted to the pressure-holding head 211 through the elastic element 213, so that the pressure-holding head 211 can press against the workpiece. During the process of the connecting part 212 moving toward the pressure-holding head 211, the elastic element 213 undergoes elastic deformation to provide a buffering effect.

[0074] In some embodiments, a guide 2121 is connected between the connector 212 and the pressure holding head 211. The guide 2121 is configured to guide the connector 212 to move relative to the pressure holding head 211 along a third direction Z. In some embodiments, the guide 2121 is a slide rail, and the connector 212 is slidably connected to the mounting bracket 112 via the slide rail, thereby allowing the connector 212 to slide stably relative to the pressure holding head 211.

[0075] In some embodiments, the pressure-holding head 211 and the connector 212 are configured to abut against both ends of the elastic member 213, respectively. The pressure-holding head 211 and the connector 212 are provided with a connecting groove 2122 or a connecting protrusion 2214, and one end of the elastic member 213 is configured to be sleeved on the corresponding connecting protrusion 2214 or inserted into the corresponding connecting groove 2122.

[0076] One end of the elastic element 213 is fitted onto the connecting protrusion 2214 or inserted into the connecting groove 2122, facilitating the installation or removal of the elastic element 213 and thus making it easy to replace. After the end of the elastic element 213 is inserted into the connecting groove 2122 or fitted onto the connecting protrusion 2214, the inner wall of the connecting groove 2122 or the peripheral wall of the connecting protrusion 2214 has a constraining effect on the elastic element 213, which helps to reduce the possibility of the elastic element 213 shifting relative to the connecting element 212 or the pressure holding head 211 after being subjected to force, thereby improving the stability of the connection of the elastic element 213.

[0077] Understandably, in some embodiments, the connector 212 has a connecting groove 2122 on its sidewall facing the abutment portion 2111, and a connecting protrusion 2214 is installed on the sidewall facing the connector 212 of the abutment portion 2111. The connecting protrusion 2214 is columnar and extends in the Z-direction towards the connector 212. One end of the elastic member 213 is fitted onto the connecting protrusion 2214 of the abutment portion 2111, and the other end is inserted into the connecting groove 2122 of the connector 212, so that the elastic member 213 connects the connector 212 to the pressure head 211. In other embodiments, both the connector 212 and the abutment portion 2111 may have connecting grooves 2122 or both may have connecting protrusions 2214.

[0078] In some embodiments, the pressure holding device 100 operates as follows:

[0079] When performing a pressure-holding operation on the product, the product is first installed onto the carrier 31 of the carrier mechanism 3. Then, the drive mechanism 4 drives the carrier mechanism 3 to move along the first direction X, sequentially moving the product to the positions of multiple pressure-holding mechanisms 2. When the product moves to the position of any pressure-holding mechanism 2, the corresponding pressure-holding mechanism 2 presses against the corresponding material on the product to perform a pressure-holding operation on the corresponding material. When using this pressure-holding device 100 to perform a pressure-holding operation on multiple materials on a product, after the product moves from one pressure-holding mechanism 2 to another, there is no need to re-clamp the product, which reduces the number of times the product can be clamped and improves the efficiency of performing a pressure-holding operation on multiple materials on a product.

[0080] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
