Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to an automatic alignment and assembly fixture and an automatic alignment and assembly method. Background Technology

[0002] Electronic products such as Bluetooth headsets include a tail plug, a tube, and a ribbon cable connecting the tail plug and the tube. Adhesive is applied to the inner ring of the tube and the outer ring of the tail plug. The tail plug is then inserted into the tube, and the two are bonded together. The tail plug must enable signal transmission frequency, receive call signals, and have an IPX45 waterproof rating. During assembly, the tail plug and tube are in their preset positions, and the two ends of the ribbon cable are connected to the tail plug and tube respectively. A tool is used to manually manipulate the ribbon cable to form an "S" shape to avoid interfering with the inner ring adhesive path of the tube. A suction pen is used to hold the tail plug in place, and then the suction pen is removed. However, because the "S"-shaped ribbon cable is elastic, removing the suction pen causes the tail plug to spring back under the stress of the ribbon cable. This causes the seal test between the tail plug and the tube to fail, resulting in call leakage and failure to meet the waterproof requirements for shipment. In addition, irregular stacking may occur after the ribbon cable springs back, causing the antenna to radiate electromagnetic waves outward. The close proximity of the ribbon cable's exit point to the antenna's transmission power area leads to abnormal Bluetooth reception sensitivity, causing Bluetooth environment testing to fail and preventing the signal transmission frequency from being achieved. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic alignment and assembly fixture and an automatic alignment and assembly method to avoid the ribbon cable from popping out and to ensure the product's sealing and the effectiveness of Bluetooth environment testing.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] An automatic alignment and assembly fixture includes a support module, wherein the support module is provided with:

[0006] A rotary pressing module includes a pressing component and a rotating component rotatably connected to the pressing component. A first structure is located on the rotating component and rotates with the rotating component to face a second structure carried on a carrier. The pressing component is movable along a first direction and drives the rotating component and the first structure to move. When the pressing component is in a preset position, the second structure is connected to the first structure to form an assembly.

[0007] A cable-pulling module includes a toggle member and a cam rod capable of moving simultaneously in a second direction. The toggle member is used to pull the cable located between the first structure and the second structure. When the pressing component moves to move the second structure toward the first structure, the pressing component pushes against the cam rod to move the cam rod and the toggle member away from the cable. When the pressing component is in a preset position, the toggle member moves out of the space between the second structure and the first structure.

[0008] A limiting module, including a limiting element for limiting the position of the assembly.

[0009] In some possible implementations, the rotary pressing module further includes a pressing support plate and an elastic buckle rotatably and elastically connected to the pressing support plate, the pressing support plate being fixed to the support module; the pressing assembly includes a pressing block, the rotary assembly being rotatably connected to the pressing block, the pressing block being connected to the pressing support plate via an elastic element and having a tendency to move away from the pressing support plate along the first direction, and when the elastic element is compressed to a preset state, the elastic buckle can engage with the pressing block to connect the second structure with the first structure.

[0010] In some possible implementations, the rotary pressing module further includes a locking block with a hook, the locking block being fixed to the pressing support plate, and in the initial state of the elastic element, the pressing block being limited to the hook.

[0011] In some possible implementations, the pressing support plate includes a first support plate, and a second and a third support plate, both perpendicular to the first support plate. The first support plate is fixed to the support module. The pressing block is connected to the first support plate via an elastic element. The elastic buckle rotates and is elastically connected to the second support plate. The pressing block is slidably connected to the third support plate along the first direction.

[0012] In some possible implementations, the pressing assembly includes a pressing bearing disposed on the pressing block, the cam rod includes an inclined surface, the pressing bearing abuts against the inclined surface, and the inclined surface is inclined in a direction away from the pressing bearing from a direction away from the toggle member to a direction close to the toggle member.

[0013] In some possible implementations, the toggle cable module includes a fixed plate and an adapter. The fixed plate is fixed to the support module, the toggle member and the cam rod are disposed on the adapter, and the adapter is slidably connected to the fixed plate along the second direction.

[0014] In some possible implementations, the toggle cable module further includes an adapter block, which includes a first connecting block and a second connecting block arranged at an angle. The first connecting block is connected to the adapter and can be adjusted in the first direction. The toggle member is connected to the first connecting block and can be adjusted in the third direction.

[0015] In some possible implementations, the rotating assembly includes a rotating shaft, a rotating arm connected to the rotating shaft, and an adsorption element disposed on the rotating arm. The rotating shaft is rotatably connected to the pressing assembly. The rotating shaft is a hollow shaft, with one end connected to a vacuum pump and the other end connected to the adsorption element. The adsorption element is used to adsorb the first structure.

[0016] In some possible implementations, the limiting module further includes a base plate and two first blocks disposed on the base plate. The base plate is fixed to the support module. The limiting member is slidably connected to the base plate along a second direction. The limiting member is provided with a limiting groove that matches the shape of the assembly. When the limiting member abuts against one of the first blocks, the assembly is disposed in the limiting groove.

[0017] An automatic alignment assembly method using the automatic alignment assembly fixture described above includes:

[0018] A first structure is placed on a rotating assembly, and a second structure is placed on a carrier. The rotating assembly rotates the first structure so that the first structure faces the second structure and is located above the second structure.

[0019] The actuating element and the cam rod are simultaneously pushed toward the cable between the first structure and the second structure, causing the cable to bend.

[0020] The pressing component drives the rotating component to move downward, while the first structure moves toward the second structure, and the pressing component pushes against the cam rod, causing the cam rod and the actuating member to move away from the cable; when the pressing component is in a preset position, the actuating member moves out from between the first structure and the second structure, and the first structure and the second structure are connected to form an assembly;

[0021] The movement of the limiting component limits the movement of the assembly.

[0022] The first structure detaches from the rotating assembly, which rotates in the opposite direction, exposing the first structure.

[0023] The pressure-holding module presses against the first structure to maintain pressure.

[0024] The beneficial effects of this invention are:

[0025] This invention provides an automatic alignment and assembly fixture and an automatic alignment and assembly method. By rotating a pressing module, a cable-guiding module, and a limiting module, the cable is guided into a preset "S" shape for product assembly. This prevents interference between the cable and the inner rings of the first and second structures, cable springback, and stress-induced springback of the first structure from the cable. This ensures the installation stability of the first and second structures, thereby meeting sealing performance requirements and guaranteeing that the cable maintains an "S" shape without irregular stacking due to springback, thus ensuring effective Bluetooth environment testing. The automatic alignment and assembly method uses the above structure to prevent the first structure from springing off after cable guidance and movement. A pressure-holding structure then presses against the first structure to prevent it from springing off the second structure, ensuring reliable product structural connections.

[0037] 100. Second structure. Detailed Implementation

[0038] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] like Figures 1-4 As shown, this embodiment provides an automatic alignment and assembly fixture for automatically aligning and assembling products. The product includes a first structure, a second structure 100, and a ribbon cable. The ribbon cable connects the first structure and the second structure 100, and the first structure and the second structure 100 are connected. The product can be any electronic product; this embodiment uses a Bluetooth headset as an example. The first structure is a tail plug, the second structure 100 is a conduit, and the ribbon cable connects the tail plug and the conduit's tail end.

[0042] The automatic alignment and assembly fixture includes a support module 1 and a rotating pressing module 3, a guide wire module 4, and a limiting module 5 disposed on the support module 1. The rotating pressing module 3 includes a pressing component 31 and a rotating component 32 rotatably connected to the pressing component 31. A first structure can be located on the rotating component 32 and rotate with the rotating component 32 to face the second structure 100 carried on the carrier 2. The pressing component 31 can move along a first direction and drive the rotating component 32 and the first structure to move. When the pressing component 31 is in a preset position, the second structure 100 is connected to the first structure to form an assembly. The cable guide module 4 includes a toggle member 41 and a cam rod 42 that can move simultaneously in a second direction. The toggle member 41 is used to toggle the cable located between the first structure and the second structure 100, deforming it into a preset shape such as an "S" shape. When the pressing component 31 moves to move the second structure 100 toward the first structure, the pressing component 31 pushes against the cam rod 42, causing the cam rod 42 and the toggle member 41 to move away from the cable. When the pressing component 31 is in a preset position, the toggle member 41 moves out of the space between the second structure 100 and the first structure. The limiting module 5 includes a limiting member 51, which is used to limit the assembly. Optionally, the limiting member 51 and the toggle member 41 are located on both sides of the assembly to prevent structural interference.

[0043] In this embodiment, the first direction, the second direction, and the third direction are perpendicular to each other, and the first direction is the up-down direction, the second direction is the front-back direction, and the third direction is the left-right direction, which is used as an example for illustration.

[0044] For example, the support module 1 includes a first fixing plate 11, a second fixing plate 12, a third fixing plate 13, and a fixing block 14. The third fixing plate 13 and the second fixing plate 12 are mounted on the first fixing plate 11 in a front-rear direction, and the fixing block 14 is mounted on the left side of the first fixing plate 11. The rotary pressing module 3 is mounted above the second fixing plate 12, the limiting module 5 is mounted above the third fixing plate 13, the cable guide module 4 is mounted on the right side of the first fixing plate 11, and the carrier 2 is mounted on the left side of the first fixing plate 11 via the fixing block 14. The carrier 2 includes a limiting part 21, and the second structure 100 ensures positional accuracy through the limiting part 21.

[0045] After the rotating assembly 32 rotates the first structure toward the second structure 100, the cable guide module 4 moves the cable between the first and second structures 100. Then, the pressing assembly 31 presses down, pushing the cam rod 42 to move the actuating member 41 away from the cable, i.e., moving it out from between the first and second structures 100. During this process, the first structure moves toward the second structure 100 and connects to form an assembly. The limiting member 51 limits the assembly, fixing the first and second structures 100 together and preventing the first structure from springing upwards.

[0046] By rotating the pressure module 3, the cable guide module 4, and the limiting module 5, the cable guide is moved to an "S" shape and the product is assembled. This prevents interference between the cable guide and the inner ring of the first and second structures 100, prevents the cable guide from springing back, and prevents the first structure from being subjected to stress springback from the cable guide. This ensures the installation stability of the first and second structures 100, thereby meeting the sealing performance requirements and ensuring that the cable guide is in an "S" shape without irregular stacking due to springback. This makes the Bluetooth environment test valid.

[0047] Optionally, the automatic alignment and assembly fixture also includes a pressure-holding module. The first structure detaches from the rotating component 32, which rotates in the opposite direction to expose the first structure. The pressure-holding module presses against the first structure to maintain pressure and prevent it from springing off the second structure 100. The first and second structures 100 are bonded together with adhesive. Before the first and second structures 100 are connected, at least one of them is coated with adhesive. The pressure-holding module holds pressure on the assembly for a period of time to ensure a firm adhesive bond before removing it, ensuring bonding reliability and further guaranteeing the reliability of the product structure connection. Specifically, the pressure-holding module includes a cylinder and a pressure plate. The cylinder is fixed to the frame of the equipment, which is fixed relative to the support module 1. The cylinder drives the pressure plate to press against the first structure.

[0048] The rotating pressing module 3 also includes a pressing support plate 33 and an elastic buckle 38 rotatably connected to the pressing support plate 33. The elastic buckle 38 is elastically connected to the pressing support plate 33, and the pressing support plate 33 is fixed to the support module 1. The pressing assembly 31 includes a pressing block 311, and a rotating assembly 32 is rotatably connected to the pressing block 311. The pressing block 311 is connected to the pressing support plate 33 through an elastic member 34 and has a tendency to move away from the pressing support plate 33 in a first direction. When the elastic member 34 is compressed to a preset state, the elastic buckle 38 can engage with the pressing block 311 to connect the second structure 100 with the first structure. In the initial state, the elastic member 34 causes the pressing block 311 and the pressing support plate 33 to spring apart, and the elastic buckle 38 separates from the pressing block 311. When the first structure is located in the rotating assembly 32, there is a gap between the first structure and the second structure 100. When the pressing block 311 is pressed down, the gap between the first structure and the second structure 100 is reduced. When the pressing block 311 is pressed down to the preset position, the elastic element 34 is compressed to the preset state, and the elastic buckle 38 can be connected to the pressing block 311 to prevent the pressing block 311 from rebounding under the action of the elastic element 34, thereby making the first structure and the second structure 100 stably connected.

[0049] The pressing support plate 33 includes a first support plate 331, and a second support plate 332 and a third support plate 333, both perpendicular to the first support plate 331. For example, the second support plate 332 is located on the left side, and the third support plate 333 is located on the rear side. The first support plate 331 is fixed to the support module 1. The pressing block 311 is connected to the first support plate 331 through an elastic member 34. The elastic buckle 38 rotates and is elastically connected to the second support plate 332. The pressing block 311 is slidably connected to the third support plate 333 along the first direction.

[0050] Specifically, the elastic buckle 38 includes a buckle body 381, a pin 382, ​​and a buckle spring 383. The pin 382 is mounted on the second support plate 332, and the buckle body 381 is rotatably connected to the pin 382. The buckle spring 383 connects the buckle body 381 and the second support plate 332. The lower pressure block 311 and the buckle body 381 can engage or disengage. When they are disengaged, the buckle spring 383 is in an extended state. After the lower pressure block 311 is pressed down to a preset position, the buckle spring 383 returns to its original position, and the buckle body 381 rotates to engage with the lower pressure block 311. Optionally, the upper part of the buckle body 381 has a guide surface on the side facing the lower pressure block 311 to facilitate pressing down the lower pressure block 311, ensure smooth operation, and prevent structural interference.

[0051] A first guide assembly 37 is provided between the third support plate 333 and the lower pressure block 311. Specifically, it includes a guide rail fixed on the lower pressure block 311 and a slider mounted on the third support plate 333. The slider is slidably connected to the guide rail, which is arranged in the vertical direction to ensure that the two slide relative to each other in the first direction, thereby improving the movement accuracy. A guide post 36 is also installed on the first support plate 331. The guide post 36 extends in the vertical direction, and the lower pressure block 311 is sleeved on the guide post 36. The two are slidably connected, which further improves the movement accuracy. The elastic element 34 is a spring, which is sleeved on the guide post 36 and its two ends abut against the first support plate 331 and the lower pressure block 311, respectively, for easy installation.

[0052] The rotating assembly 32 includes a rotating shaft 321, a rotating arm 322 connected to the rotating shaft 321, and an adsorption member 323 disposed on the rotating arm 322. The rotating shaft 321 is rotatably connected to the pressing assembly 31. The rotating shaft 321 is a hollow shaft, with one end connected to a vacuum pump and the other end connected to the adsorption member 323. The adsorption member 323 is used to adsorb the first structure. The hollow shaft and the adsorption member 323 are connected by an air pipe. When the vacuum pump is turned on, the adsorption member 323 draws a vacuum to adsorb the first structure. When the vacuum pump is turned off, the first structure detaches from the adsorption member 323. The structure is compact, convenient, and reliable to use. For example, the rotating shaft 321 is rotatably connected to the pressing block 311 through a radial bearing, and the rotating arm 322 and the rotating shaft 321 are connected through a thrust bearing.

[0053] In one embodiment, the adsorption member 323 has a contoured groove 3231, a first structure is disposed within the contoured groove 3231, the adsorption member 323 has an air hole communicating with the contoured groove 3231, and an air pipe connector 3232 is installed on the adsorption member 323. The contoured groove 3231, the air hole, the air pipe connector 3232, the air pipe, and the hollow shaft are interconnected. Optionally, the rotating arm 322 is provided with a fixed seat 3221, and the air pipe is tied to the fixed seat 3221 by a cable tie.

[0054] Furthermore, the adsorption element 323 is slidably connected to the guide post 3233, the guide post 3233 is fixed to the rotating arm 322, and a downward pressure spring 3234 is provided between the adsorption element 323 and the rotating arm 322. The adsorption element 323 and the rotating arm 322 are elastic. When the downward pressure block 311 moves downward, it prevents the first structure and the second structure 100 from making hard contact, ensuring that the product is not damaged.

[0055] Optionally, the pressing block 311 is provided with two second stops 3111, and the rotating arm 322 is L-shaped. When the rotating assembly 32 is in its initial position, the rotating arm 322 is confined to one of the second stops 3111. When the rotating assembly 32 rotates to a preset position so that the first structure faces the second structure 100, the rotating arm 322 is confined to the other second stop 3111. Furthermore, the two second stops 3111 are respectively provided with second magnetic elements 3112, such as magnets, so that the rotating arm 322 is attracted to the second stop 3111 by the second magnetic elements 3112, ensuring structural stability.

[0056] The pressing assembly 31 includes a pressing bearing 312 disposed on the pressing block 311, and the cam rod 42 includes an inclined surface 421. The pressing bearing 312 abuts against the inclined surface 421. The inclined surface 421 is inclined in a direction away from the pressing bearing 312 from the direction away from the actuating member 41 to the direction near the actuating member 41, that is, the inclined surface 421 is inclined downward from back to front. When the pressing block 311 moves downward, the pressing bearing 312 moves downward with the pressing block 311 and presses against the inclined surface 421 of the cam rod 42. The downward pressure on the cam rod 42 is converted into a backward thrust, causing the cam rod 42 to move backward, thereby causing the actuating member 41 to be pulled out from between the first structure and the second structure 100 as the cam rod 42 moves.

[0057] The rotary pressing module 3 also includes a locking block 35, which has a hook 351. The locking block 35 is fixed to the pressing support plate 33. In the initial state of the elastic member 34, the pressing block 311 is limited to the hook 351. That is, the pressing block 311 is limited to the upper limit of the hook 351 and the lower limit of the elastic buckle 38. This prevents the pressing block 311 from being too high and unable to abut against the cam rod 42. Specifically, the actuating member 41 is a pin, such as a metal pin or a metal sheet.

[0058] Specifically, the lower pressure block 311 is provided with a bearing fixing block 313, and the lower pressure bearing 312 is installed on the bearing fixing block 313. The bearing fixing block 313 can be adjusted in the left and right direction. The clamping block 35 is provided with an elongated hole, which can be adjusted in the up and down direction, thereby improving the applicability of the fixture.

[0059] The toggle cable module 4 includes a fixed plate 43 and an adapter 44. The fixed plate 43 is fixed to the support module 1. The toggle member 41 and the cam rod 42 are disposed on the adapter 44. The adapter 44 is slidably connected to the fixed plate 43 in a second direction, so that the toggle member 41 and the cam rod 42 can move simultaneously. The toggle member 41 and the cam rod 42 slide on the fixed plate 43 through the adapter 44 to ensure smooth movement. The toggle cable module 4 also includes a second guide assembly 46, such as a guide rail and a slider slidably connected to the guide rail. The guide rail is fixed to the fixed plate 43, and the slider is connected to the adapter 44. The guide rail extends in the front-back direction.

[0060] Optionally, the fixing plate 43 is further provided with two third stops 47, and the adapter 44 is provided with a blocking part 441, which is positioned between the two third stops 47 to prevent slippage. Furthermore, each of the two third stops 47 is provided with a magnet. The blocking part 441 can be positioned at two extreme positions by being attracted to either third stop 47 by the magnet. When in the two extreme positions, the actuating member 41 is in the actuating state and the disengaged state respectively, ensuring operational accuracy. The distance between the two third stops 47 is the fixed stroke of the actuating member 41.

[0061] Furthermore, the toggle cable module 4 also includes an adapter block 45, which includes a first connecting block 451 and a second connecting block 452 arranged at an angle. For example, the two are arranged at a 90° angle. The first connecting block 451 and the second connecting block 452 each have an elongated hole. The first connecting block 451 is connected to the adapter 44 and can be adjusted in a first direction. The toggle member 41 is connected to the first connecting block 451 and can be adjusted in a third direction, which improves applicability.

[0062] The limiting module 5 also includes a base plate 52 and two first stops 53 disposed on the base plate 52. The base plate 52 is fixed to the support module 1. The limiting member 51 is slidably connected to the base plate 52 along the second direction. The limiting member 51 is provided with a limiting groove that matches the shape of the assembly. When the limiting member 51 abuts against one of the first stops 53, the assembly is disposed in the limiting groove, thereby simultaneously limiting the first structure and the second structure 100. When the limiting member 51 abuts against the other first stop 53, the assembly is separated from the limiting groove. Optionally, the base plate 52 is provided with a third guide assembly 54. The third guide assembly 54 includes a guide rail and a slider slidably connected to the guide rail. The guide rail is fixed to the base plate 52 along the front-back direction. The limiting member 51 is connected to the slider, thereby realizing that the limiting member 51 is slidably connected to the base plate 52. The first stop 53 is provided with a first magnetic element 55, such as a magnet. The limiting element 51 can be magnetically attracted to any of the first stop 53 by the magnet, ensuring that the limiting element 51 can stably abut against the first stop 53, thereby fixing the assembly in the limiting groove, preventing the first structure from popping up and ensuring stability.

[0063] Furthermore, the limiting member 51 includes a first limiting block 511, a mounting block 512, and a second limiting block 513. The mounting block 512 is connected to the slider, and both the first limiting block 511 and the second limiting block 513 are connected to the mounting block 512. The first limiting block 511 has a limiting groove, and the second limiting block 513 is limited between two first stops 53.

[0064] like Figure 5 As shown, the automatic alignment assembly fixture also includes a pressure holding module. This embodiment also provides an automatic alignment assembly method using the above-mentioned automatic alignment assembly fixture, including the following steps:

[0065] Step 1: Place the first structure on the rotating assembly 32 with the first structure facing upwards, and place the second structure 100 on the carrier 2. After the rotating assembly 32 rotates the first structure 180°, the first structure faces downwards and is positioned above the second structure 100. In this embodiment, the tail plug faces the tail end of the pipe.

[0066] The ribbon cable is located between the conduit and the tail plug. Specifically, the ribbon cable can be installed after the positions of the first and second structures 100 are relatively fixed, or the ribbon cable can be pre-installed on one of the structures and then installed on the other structure. As long as the ribbon cable is located between the two structures, it is acceptable.

[0067] Step 2: Push the actuating element 41 and the cam rod 42 forward simultaneously, i.e., towards the ribbon cable, to make the ribbon cable bend into an "S" shape.

[0068] Step 3: Press down the pressing component 31. The pressing component 31 drives the rotating component 32 to move downwards. At the same time, the first structure moves toward the second structure 100, and the pressing component 31 pushes against the cam rod 42, causing the cam rod 42 and the actuating member 41 to move away from the cabling, i.e., move backwards. When the pressing component 31 is in the preset position, the actuating member 41 moves out from between the first structure and the second structure 100, and the first structure and the second structure 100 are connected to form an assembly.

[0069] Step 4: The limiting member 51 moves backward to limit the assembly, that is, to fix the first structure and the second structure 100 together and prevent the first structure from springing upward.

[0070] By rotating the pressure module 3, the cable guide module 4, and the limiting module 5, the cable guide is moved to an "S" shape and the product is assembled. This prevents interference between the cable guide and the inner ring of the first and second structures 100, prevents the cable guide from springing back, and prevents the first structure from being subjected to stress springback from the cable guide. This ensures the installation stability of the first and second structures 100, thereby meeting the sealing performance requirements and ensuring that the cable guide is in an "S" shape without irregular stacking due to springback. This makes the Bluetooth environment test valid.

[0071] Optionally, before step three, the method further includes applying adhesive to at least one of the first and second structures 100. In step three, the first and second structures 100 are bonded together to form an assembly.

[0072] Step 5: The first structure detaches from the rotating component 32, and the rotating component 32 rotates in the opposite direction, exposing the first structure;

[0073] Step Six: The pressure-holding module presses against the first structure to maintain pressure and prevent it from springing off the second structure 100. This pressure is maintained for a period of time until the adhesive is firmly bonded before being removed, ensuring bonding reliability and further guaranteeing the structural connection reliability. Specifically, the pressure-holding module includes a cylinder and a pressure plate. The cylinder is fixed to the frame of the equipment, which is fixed relative to the support module 1. The cylinder drives the pressure plate to press against the first structure.
