[0061] This invention proposes an assembly pressure holding device.

[0062] In embodiments of the present invention, such as Figures 1-5 As shown, the assembly pressure holding device includes a worktable 1, a pressure holding mechanism 2, and a flipping mechanism 3.

[0063] The workbench 1 is provided with a first tooling 5 for installing a first material; the pressure holding mechanism 2 includes a second tooling 21 for installing a second material and a pressure holding module 22 connected to the second tooling 21; the flipping mechanism 3 is provided on the workbench 1 and has a flipping cover assembly 31 that can be flipped relative to the workbench 1, and the flipping cover assembly 31 is provided with a mounting position 3121 for installing the second tooling 21.

[0064] The flip cover assembly 31 has an open state and a closed state:

[0065] When in the open state, the mounting position 3121 is away from the worktable 1 and is used to install the second tooling 21;

[0066] When in the latching state, the mounting position 3121 is opposite to the worktable 1 so that the second material in the second tooling 21 is aligned and assembled with the first material in the first tooling 5, and the pressure holding module 22 applies pressure between the second material and the first material.

[0067] In this embodiment, the workbench 1 serves to support and install various mechanical components. The workbench 1 can be understood as the base or housing of a machine tool, and its internal components can be control devices or mechanical devices, etc., and its specific structure is not limited here. A first tooling 5 is provided on the workbench 1. The first tooling 5 is used to install the first material to be assembled. Optionally, the first tooling 5 can be fixedly or detachably fixed to the surface of the workbench 5. The pressure holding mechanism 2 includes a second tooling 21 and a pressure holding module 22. The second tooling 21 is used to install the second material to be assembled, and the pressure holding module 22 is used to apply a pressure to the second material towards the first material after the second material and the first material are aligned and assembled. The flipping mechanism 3 is located on the workbench 1 and has a flip-top assembly 31 that can flip relative to the workbench 1. By providing a mounting position 3121 for installing the second tooling 21 on the flip-top assembly 31, when the flip-top assembly 31 can drive the second material in the second tooling 21 to flip so that it is aligned with and assembled with the first material in the first tooling 5, the pressure holding module 22 then performs the pressure holding function.

[0068] As an example, the following describes how this assembly and pressure-holding device performs the assembly and pressure-holding operations on the first and second materials:

[0069] First, the flip-top assembly 31 is flipped relative to the worktable 1 to the open state. At this time, the mounting position 3121 is away from the worktable 1, for example, the mounting position 3121 faces upward or to the side, so as to install the second tooling 21 carrying the second material into the mounting position 3121; at the same time, the first tooling 5 carrying the first material is installed onto the table surface of the worktable 1.

[0070] Then, flip the cover assembly 31 to the snap-fit ​​state. At this time, the mounting position 3121 is opposite to the workbench 1, so that the second tooling 21 is opposite to the first tooling 5, thereby aligning and assembling the second material in the second tooling 21 with the first material in the first tooling 5. Then, the pressure holding module 22 applies pressure to the second material and the first material to hold the pressure for a certain period of time, thus completing the assembly of the first material and the second material.

[0071] It should be noted that, in this embodiment, the first material and the second material have been glued at corresponding positions before the assembly and pressure holding processes. The specific glue dispensing process can refer to conventional glue dispensing processes and is not limited here.

[0072] Understandably, the connection between the second tooling 21 and the mounting position 3121 of the flip assembly 31 can be determined according to the actual situation. For example, it can be a non-removable fixed connection or a detachable fixed connection. When it is a non-removable fixed connection, it can be glued, threaded, or welded. In this way, the second tooling 21 and the flip assembly 31 are not detachable. Therefore, during the flip movement of the flip assembly 31, the reliability of the second tooling 21 is ensured and it is prevented from falling off. If the fixing method is detachable, magnetic fixing, snap-fit ​​fixing, or threaded connection can be used. In this way, when the flip-top assembly 31 rotates, the second tooling 21 can be kept in place. After the second material is aligned and assembled with the first material, the second tooling 21 can be removed from the flip-top assembly 31 during the pressure holding process. The mating structure of the second tooling 21 and the first tooling 5 can be removed from the workbench 1 as a whole module and placed in another position for pressure holding. This allows the assembly pressure holding device to perform the assembly pressure holding process for the next product, speeding up the production cycle and improving efficiency. In summary, the connection relationship between the second tooling 21 and the flip-top assembly 31 can be determined according to the actual situation and is not limited here.

[0073] As an example, a first positioning pin 2122 can be provided on the first tooling 21, and correspondingly, a first positioning hole can be provided on the first tooling 5. The limiting effect of the first positioning pin 2122 and the first positioning hole ensures the assembly accuracy of the second material and the first material. Optionally, two or more first positioning pins 2122 with different outer diameters and two or more first positioning holes with different inner diameters can be provided. The matching of different hole diameters achieves the error-proof effect. Accordingly, in order to further improve the assembly accuracy, a second positioning pin 3122 for positioning the second tooling 21 can be provided at the mounting position 3121 of the flipping component 31.

[0074] As an example, the relative flipping motion between the flip-top assembly 31 and the worktable 1 can be manual or automatic.

[0075] As an example, the first tooling 5 is detachably fixed to the worktable 1.

[0076] In the pressure-holding assembly device of this invention, a first tooling 5 for mounting a first material is provided on the workbench 1. The flipping mechanism 3 has a flip-top assembly 31 that can flip relative to the workbench 1. The flip-top assembly 31 has a mounting position 3121 for mounting a second tooling 21. When the flip-top assembly 31 is flipped to the open state, the mounting position 3121 is away from the workbench 1 to facilitate the mounting of the second tooling 21 carrying the second material. Then, the flip-top assembly 31 is flipped to the snap-fit ​​state, causing the second tooling 21 to be aligned with the first tooling 5, so that the second material and the first material are aligned and assembled. The pressure-holding module 22 applies a pressure-holding force to the second material and the first material to achieve the pressure-holding action. This realizes the action of upside-down assembly and pressure holding of the product, improving the product assembly efficiency.

[0077] In one embodiment of this application, please refer to Figures 5-11 The second tooling 21 is provided with a tooling slot 212a for installing the second material; the pressure holding module 22 includes a movable pressure holding member 221 and a self-locking drive assembly 222. The self-locking drive assembly 222 is pulsatorically connected to the pressure holding member 221 so that the pressure holding member 221 moves between a clearance position away from the tooling slot 212a and a pressure holding position extending into the tooling slot 212a; in the open state, the self-locking drive assembly 222 drives the pressure holding member 221 to move to the clearance position; in the latching state, the self-locking drive assembly 222 is used to drive the pressure holding member 221 to move to the pressure holding position to abut against the second material after the second material and the first material are aligned and assembled.

[0078] In this embodiment, the second tooling 21 is provided with a tooling groove 212a. In order to facilitate product assembly, the tooling groove 212a is located on the side of the second tooling 21 away from the mounting position 3121, so that the second material can be smoothly aligned with the first tooling 5 when in the snap-fit ​​state.

[0079] By configuring the pressure holding module 22 to include a pressure holding member 221 and a self-locking drive assembly 222, the pressure holding member 221 can reciprocate relative to the second tooling 21. Optionally, the pressure holding member 221 is located on one side of the tooling groove 212a and can extend and retract relative to the tooling groove 212a. When the pressure holding member 221 retracts outside the tooling groove 212a, the second material can be smoothly installed in the tooling groove 212a, at which time the pressure holding member 221 is in the clearance position. When the pressure holding member 221 extends into the tooling groove 212a, it can abut against the second material and apply a pressure holding force towards the first material to the second material, at which time the pressure holding member 221 is in the pressure holding position.

[0080] Understandably, the self-locking drive assembly 222 restricts and drives the position of the pressure-holding component 221. When the flip-top assembly 31 is in the open state, the second material after dispensing needs to be installed into the tooling slot 212a. At this time, the self-locking drive assembly 222 drives the pressure-holding component 221 to the clearance position to avoid interference with the installation of the second material, allowing the second material to be smoothly installed into the tooling slot 212a. When the flip-top assembly 31 is flipped to the latching state, after the second material is aligned and assembled with the first material, a pressure-holding action is required between the second and first materials. At this time, the self-locking drive assembly 222 drives the pressure-holding component 221 to the pressure-holding position to press against the second material, thus achieving the pressure-holding action between the second and first materials.

[0081] In practical applications, the specific structure of the self-locking drive assembly 222 can be determined according to the actual situation. It can be a purely mechanical structure or an electronically controlled structure, as long as it can achieve the function of the aforementioned drive and pressure-holding component 221. For an example, please refer to... Figures 5-11 The self-locking drive assembly 222 includes a first drive structure 2221 and a self-locking limiting structure 2222. The first drive structure 2221 is movably disposed on the second tooling 21 and is connected to the pressure holding member 221 for driving the pressure holding member 221 to move to the clearance position. The self-locking limiting structure 2222 is movably disposed on the second tooling 21 for limiting the pressure holding member 221 when it moves to the clearance position. It is also used to release the pressure holding member 221 after the second material and the first material are aligned and assembled, so that the pressure holding member 221 moves to the pressure holding position.

[0082] This embodiment illustrates the structure of the self-locking drive assembly 222. The self-locking drive assembly 222 includes a first drive structure 2221 for driving the pressure-holding member 221 to the clearance position and a self-locking limiting structure 2222 for locking or releasing the pressure-holding member 221. It can be understood that when the flip-top assembly 31 is in the open state, the second material after dispensing needs to be installed into the tooling slot 212a. At this time, the first drive structure 2221 can drive the pressure-holding member 221 to the clearance position to smoothly install the second material into the tooling slot 212a. When the flip-top assembly 31 is flipped to the latched state, and before the second material is aligned and assembled with the first material, the second material still needs to be reliably installed in the tooling slot 212a. During this process, the pressure-holding member 221 still needs to be in the clearance position. Therefore, the self-locking limiting structure 2222 can limit and stop the pressure-holding member 221, preventing it from moving into the tooling slot 212a. After the second material is aligned and assembled with the first material, a pressure holding action is required for the second material and the first material. At this time, the self-locking limit structure 2222 releases the pressure holding member 221, so that the pressure holding member 221 can move to the pressure holding position to abut against the second material.

[0083] In practical applications, the first driving structure 2222, the pressure holding component 221, and the self-locking limiting structure 2222 can be linked together. For example, when the first driving structure 2222 drives the pressure holding component 221 to move to the avoidance position, the self-locking limiting structure 2222 is triggered to lock and limit the pressure holding component 221 to resume its movement. After the second material is aligned and assembled with the first material, the self-locking limiting structure 2222 can be unlocked and released from the limiting effect on the pressure holding component 221 under the action of external force (such as manual or driving components), so that the pressure holding component 221 can smoothly perform the pressure holding action on the second material.

[0084] As an example, please refer to Figure 5 , Figure 10 as well as Figure 11 The first drive structure 2221 includes a first drive part 22211, a first transmission part 22212, and a first reset member 22213. One end of the first drive part 22211 extends out of the second tooling 21. The first transmission part 22212 is disposed on the first drive part 22211 and is connected to the pressure holding member 221 in a transmission manner. The first reset member 22213 is connected to the first drive part 22211.

[0085] This embodiment illustrates the structure of the first driving structure 2221. The first driving part 22211 is movably disposed on the second tooling 21, and one end of the first driving part 22211 extends out of the second tooling 21. It can be understood that a driving force (such as manual driving or driving by a driving component) can be applied to the end of the first driving part 22211 extending out of the second tooling 21, causing the first driving part 22211 to drive the first transmission part 22212 to move, thereby driving the pressure-holding member 221 away from the tooling groove 212a to a clearance position, where it is limited and blocked by the self-locking limiting structure 2222. The first reset member 22213 serves to reset the first driving part 22211. When the driving force applied to the first driving part 22211 disappears, the first reset member 22213 can drive the first driving part 22211 to return to its initial position. Optionally, the second tooling 21 is provided with a first opening 211a for the first driving part 22211 to extend out, and the first reset member 22213 can be provided at one end of the first driving part 22211 away from the first opening 211a. As an example, the first reset member 22213 is a spring.

[0086] Understandably, the transmission connection structure between the first transmission part 22212 and the pressure holding member 221 can be determined according to the actual situation, such as inclined plane transmission, gear transmission, threaded rotation, or other transmission methods. In this embodiment, considering the simplicity of the structural layout, the first transmission part 22212 is a wedge-shaped block structure. The first transmission part 22212 is provided with a first inclined plane 22212a. Correspondingly, the part of the pressure holding member 221 that cooperates with the first transmission part 22212 can be provided with a second inclined plane 2212a. The transmission reversal function is realized through the cooperation of the two inclined planes.

[0087] Optionally, the first transmission part 22212 and the first drive part 22211 are an integral structure, which can be formed by molding or 3D printing.

[0088] As an example, please refer to Figure 5 , Figure 10 as well as Figure 11 The self-locking limiting structure 2222 includes a second driving part 22221, a first stop part 22222, and a second reset member 22223. One end of the second driving part 22221 extends out of the second tooling 21. The first stop part 22222 is disposed on the second driving part 22221 and is used to limit and stop the pressure holding member 221 when the pressure holding member 221 is in the clearance position. The second reset member 22223 is connected to the second driving part 22221.

[0089] This embodiment illustrates the structure of the self-locking limiting structure 2222. It is understood that when the first driving structure 2221 drives the pressure-holding member 221 to the clearance position, the pressure-holding member 221 and the first stop portion 22222 limit and resist each other. The first stop portion 22222 prevents the pressure-holding member 221 from moving towards the tooling groove 212a, thus achieving the position limiting function of the pressure-holding member 221. The second driving portion 22221 is movably disposed on the second tooling 21, and one end of the second driving portion 22221 extends out of the second tooling 21. It is understood that when pressure holding is required, a driving force (such as manual driving or driving component driving) can be applied to the end of the second driving portion 22221 extending from the second tooling 21 to drive the first stop portion 22222 away from the pressure-holding member 221, thereby releasing the limiting and resisting effect on the pressure-holding member 221, allowing the pressure-holding member 221 to move towards the tooling groove 212a to resist the second material and achieve the pressure holding function. The second reset member 22223 serves to reset the second drive unit 22221. When the driving force acting on the second drive unit 22221 disappears, the second reset member 22223 can drive the second drive unit 22221 and the first stop unit 22222 back to their initial positions, thus providing conditions for the next limiting action on the pressure holding member 221. Optionally, the second tooling 21 is provided with a second opening 211b for the second drive unit 22221 to extend out, and the second reset member 22223 can be located at the end of the second drive unit 22221 opposite to the second opening 211b. As an example, the second reset member 22223 is a spring.

[0090] Furthermore, the second drive unit 22221 is provided with a guide pin to guide the movement of the second drive unit 22221.

[0091] In one embodiment of this application, please refer to Figure 5 , Figure 10 as well as Figure 11The self-locking drive assembly 222 also includes a limiting member 22214 disposed on the first drive structure 2221. The limiting member 22214 can extend and retract relative to the tooling groove 212a to avoid or limit the second material.

[0092] In this embodiment, by providing a limiting member 22214 on the first driving structure 2221, when the flip-top assembly 31 is in the open state, the first driving structure 2221 drives the limiting member 22214 to retract to avoid the tooling slot 212a, allowing the second material to be smoothly installed into the tooling slot 212a. After the second material is installed into the tooling slot 212a, the first driving structure 2221 drives the limiting member 22214 to extend into the tooling slot 212a to limit the second material, ensuring that the second material will not fall out of the tooling slot 212a during the flip-top assembly 31's rotation movement, thus guaranteeing the reliability of the second material's rotation and inverting movement. Optionally, the limiting member 22214 is located at the opening of the tooling slot 212a.

[0093] As an example, the limiting member 22214 is disposed on the first driving part 22211. When the first driving part 22211 drives the pressure holding member 221 to move away from the tooling groove 212a, the first driving part 22211 also drives the limiting member 22214 to move away from the tooling groove 212a, so that the second material can be smoothly installed into the tooling groove 212a. When the pressure holding member 221 is limited and blocked in the clearance position by the first stop part 22222, the first reset member 22213 drives the first driving part 22211 to reset, driving the limiting member 22214 to extend into the tooling groove 212a to limit the second material. Optionally, the movement direction of the pressure holding member 221 is perpendicular to the bottom wall of the tooling groove 212a, and the movement direction of the limiting member 22214 is parallel to the bottom wall of the tooling groove 212a.

[0094] In one embodiment of this application, please refer to Figures 5-11 The second tooling 21 is also provided with a guide hole 212b communicating with the tooling groove 212a. The pressure holding component 221 includes a pressure holding head 2211, a mounting base 2212 and a pressure holding elastic component 2213. The pressure holding head 2211 passes through the guide hole 212b. The mounting base 2212 is located on the side of the pressure holding head 2211 away from the tooling groove 212a and is connected to the self-locking drive assembly 222. The pressure holding elastic component 2213 is located on the side of the mounting base 2212 away from the pressure holding head 2211.

[0095] This embodiment illustrates the structure of the pressure-holding component 221. The pressure-holding head 2211 passes through a guide hole 212b. One end of the pressure-holding head 2211, away from the tooling groove 212a, is connected to the mounting base 2212. The mounting base 2212 is connected to the first transmission part 22212, so the first driving part 22211 can drive the first transmission part 22212 to drive the mounting base 2212 to move away from the tooling groove 212a. Optionally, the mounting base 2212 is provided with a second inclined surface 2212a that cooperates with the first inclined surface 22212a. Further, a second stop part 2212b is provided on one side of the mounting base 2212. The second stop part 2212b is used to limit and abut against the first stop part 22222 in the clearance position. A pressure-holding elastic element 2213 is disposed on the side of the mounting base 2212 opposite to the pressure-holding head 2211. After the first stop 22222 releases its limiting effect on the second stop 2212b, it drives the mounting base 2212 and the pressure-holding head 2211 towards the tooling groove 212a, so that the pressure-holding head 2211 extends into the tooling groove 212a and presses against the second material to achieve pressure holding. Optionally, the pressure-holding elastic element 2213 is a spring.

[0096] As an example, the first drive unit 22211 is provided with an oblong hole through which the pressure head 2211 passes to ensure the reliability of the cooperation between the two.

[0097] In one embodiment of this application, please refer to Figure 5 , Figure 10 as well as Figure 11 The second tooling 21 includes a tooling base 211 and a second tooling body 212. The tooling base 211 is detachably installed in the mounting position 3121 and is provided with a tooling positioning hole 2111. The second tooling body 212 is positioned and installed on the tooling base 211 through the tooling positioning hole 2111. The tooling groove 212a is provided on the side of the second tooling body 212 away from the tooling base 211. The pressure holding member 221 is provided between the second tooling body 212 and the tooling base 211, and the self-locking drive assembly 222 is provided between the second tooling body 212 and the tooling base 211.

[0098] This embodiment illustrates the structure of the second tooling 21. The tooling base 211 is used to install on the mounting position 3121 of the flip-top assembly 31, and the second tooling body 212 is used to install the second material. The tooling groove 212a is located on the side of the second tooling body 212 away from the tooling base 211. It can be understood that the guide hole 212b penetrates both sides of the thickness direction of the second tooling body 212, the pressure holding head 2211 passes through the guide hole 212b, and the mounting base 2212 is located between the second tooling body 212 and the tooling base 211. Correspondingly, the first driving part 22211 is located between the second tooling body 212 and the tooling base 211, and the first opening 211a is located between the second tooling body 212 and the tooling base 211 to allow the first driving part 22211 to extend out. The self-locking limiting structure 2222 is provided on the tooling base 211, and the second opening 211a is provided on the tooling base 211 so that the second driving part 2221 is exposed through the second opening 211a so as to facilitate manual or driving operation.

[0099] In some other embodiments, please refer to Figure 5 and Figure 9 To adapt to different product requirements, such as when other components on the first material need to be pressurized, additional pressurizing components 24 can be provided on the outer periphery of the tooling groove 212a. The pressurizing components 24 include a fourth reset member 243, an equal-height column 242, and a pressurizing plate 241. The fourth reset member 243 is connected to the bottom wall of the tooling groove 212a, and the equal-height column 242 connects the fourth reset member 243 to the pressurizing plate 241. Thus, when the second tooling 21 is opposite to the first tooling 5, the pressurizing plate 241 can pressurize the parts on the first material that require pressurization. The pressurizing plate 241 has through holes 2411 adapted to the second material to prevent the second material from being assembled with the first material and to avoid interference.

[0100] In one embodiment of this application, please refer to Figure 4 , Figure 5 as well as Figure 10 The assembly pressure holding device also includes a claw assembly 23, which has two hooks 231 disposed on opposite sides of the second tooling 21. The two hooks 231 are used to hold the first tooling 5 when the second tooling 21 is aligned with the first tooling 5.

[0101] In this embodiment, a claw assembly 23 is provided on the second tooling 21, so that when the second tooling 21 is aligned with the first tooling 5, the hook 231 of the claw assembly 23 holds the first tooling 5 to clamp the second tooling 21 and the first tooling 5, thereby further improving the assembly and pressure holding effect.

[0102] Furthermore, the claw assembly 23 also includes two hook shafts 232, an elastic arm 233, and two third reset members 234. The two hook shafts 232 are respectively connected to the two hooks 231 and the second tooling 21 so that the hooks 231 can rotate relative to the second tooling 21. The elastic arm 233 is connected to the self-locking drive assembly 222. The two ends of the elastic arm 233 extend to both sides of the second tooling 21 and are respectively connected to the two hooks 231. The self-locking drive assembly 222 can drive the elastic arm 233 to open the two hooks 231. The two third reset members 234 are respectively connected to the two hooks 231 and the second tooling 21 so as to drive the two hooks 231 to retract.

[0103] This embodiment illustrates the structure of the claw assembly 23. The elastic arm 233 is movably disposed on the second tooling 21. The two ends of the elastic arm 233 extend outward to connect to the two hooks 231. The self-locking drive assembly 222 is connected to the elastic arm 233 in a transmission manner. Thus, the self-locking drive assembly 222 can drive the two hooks 231 to open or retract through the elastic arm 233.

[0104] As an example, the elastic arm 233 is connected to the first drive unit 22211, and the elastic arm 233 can be driven by the first drive unit 22211 to move so that the two hooks 231 open, so as to facilitate the assembly and disassembly of the second tooling 21 and the first tooling 5. Optionally, the elastic arm 233 is a steel wire.

[0105] Optionally, the third reset member 234 is a spring, which serves to reset the hooks 231, causing the two hooks 231 to retract, thereby ensuring the holding force of the hooks 231.

[0106] Optionally, the second tooling 21 is provided with hook baffles 2121 on both sides to limit the two hooks 231 and prevent the two hooks 231 from merging.

[0107] In one embodiment of this application, please refer to Figures 1-5 The flipping mechanism 3 also includes a bracket 32 ​​fixedly mounted on the workbench 1. The flipping assembly 31 includes a flipping cover plate 311 and a support plate 312. The flipping cover plate 311 is rotatably connected to the bracket 32. The support plate 312 is movably mounted on one side of the flipping cover plate 311. The side of the support plate 312 away from the flipping cover plate 311 is provided with an installation position 3121.

[0108] In this embodiment, the bracket 32 ​​is fixedly installed on the workbench 1. One end of the flip cover plate 311 is rotatably connected to the bracket 32. When the flip cover plate 311 flips relative to the bracket 32, it can drive the carrier plate 312 to flip. The carrier plate 312 is used to install the second tooling 21. Optionally, the carrier plate 312 is provided with a second positioning pin 3122 for positioning the second tooling 21. The carrier plate 312 and the second tooling 21 are fixed by magnetic attraction to ensure that the second tooling 21 does not fall off during the flipping movement. As an example, the carrier plate 312 is provided with multiple magnetic components, and the second tooling 21 is provided with multiple matching magnetic components.

[0109] In one embodiment of this application, please refer to Figures 1-5 The assembly pressure-holding device also includes a second drive structure 41 disposed on the flip cover plate 311. The second drive structure 41 is drivenly connected to the support plate 312 to drive the support plate 312 toward the first tooling 5 when in the snap-fit ​​state. In this embodiment, the second drive structure 41 drives the second tooling 21 toward the first tooling 5 to assemble the second material and the first material. Optionally, the second drive structure 41 is an electric cylinder to provide uniform and stable power in a direction perpendicular to the worktable 1, thereby improving assembly accuracy.

[0110] In one embodiment, please refer to Figures 1-5 The assembly pressure holding device also includes a third drive structure 42 located on one side of the support plate 312. The third drive structure 42 is used to drive the pressure holding module 22 to maintain pressure on the second material and the first material when the fastening state is engaged.

[0111] In this embodiment, the third driving structure 42 serves to drive the pressure-holding module 22. As an example, the third driving structure 42 is driven to connect with the self-locking limiting structure 2222. After the second material and the first material are aligned and assembled, the third driving structure 42 drives the self-locking limiting structure 2222 to unlock and release the pressure-holding member 221, allowing the pressure-holding member 221 to move towards the tooling groove 212a to abut against the second material, thus achieving the pressure-holding action for the second material and the first material. Further, the third driving structure 42 is a cylinder that drives the second driving part 22221 to move through the second opening 211b of the second tooling 21, thereby causing the first stop part 22222 to disengage from the second stop part 2212b of the pressure-holding member 221, achieving the unlocking function of the pressure-holding member 221. Optionally, the piston head of the third driving structure 42 is positioned opposite to the second opening 211b.

[0112] In one embodiment, please refer to Figures 1-5 The assembly pressure holding device also includes two fourth drive structures 43 disposed on the worktable 1. The two fourth drive structures 43 are disposed on both sides of the first tooling 5, for clamping the first tooling 5 after the second material and the first material are aligned and assembled.

[0113] In this embodiment, the fourth drive structure 43 plays an auxiliary clamping role, so that when the second tooling 21 is aligned and connected with the first tooling 5, the two fourth drive structures 43 are used to clamp the first tooling 5, so as to further improve the connection reliability between the second tooling 21 and the first tooling 5.

[0114] As an example, please refer to Figures 1-5 The following example illustrates the workflow of this assembly and pressure-holding device for assembling and holding pressure on the second and first materials:

[0115] The first drive unit 22211 on the second tooling 21 is pushed, causing the pressure holding head 2211 and the limiting member 22214 to move away from the tooling slot 202a to avoid collision, and the second stop part 2212b to move to the bottom of the first stop part 22222 and be limited and blocked. The second material is placed into the tooling slot 202a of the second tooling 21, and the limiting member 22214 is reset by the action of the first reset member 22213 to limit the second material. At the same time, the first material is placed into the first tooling 5 of the worktable 1.

[0116] The second fixture 21, containing the second material, is installed onto the mounting position 3121 of the support plate 312. Then, the cover plate 311 is flipped and rotated to the snap-fit ​​state. The second drive structure 41 drives the support plate 312 to move the pressure holding mechanism 2 toward the first fixture 5, so that the second fixture 21 mates with the first fixture 5. The two fourth drive structures 43 clamp the first fixture 5, and the two hooks 231 hook the first fixture 5, so that the first fixture 5 and the second fixture 21 are snap-fitted together. At this time, the second material and the first material are aligned and assembled.

[0117] The third drive structure 42 drives the second drive part 22221 to move the first stop part 22222 to release the second stop part 2212b. The pressure holding head 2211 moves toward the tooling groove 202a under the elastic force of the pressure holding elastic member 2213 to abut against the second material and maintain pressure on the second material and the first material.

[0118] The third drive structure 42 retracts to its original position, and the two fourth drive structures 43 retract to their original positions. The first tooling 5 and the pressure holding mechanism 2, which have been fastened together, are then manually removed and placed on a stationary frame for pressure holding. After a certain period of pressure holding, such as 22 minutes, the first drive part 22211 is manually pressed to remove the pressure holding mechanism 2. This process is repeated to perform the pressure holding operation for the next product assembly.

[0119] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
