Description

Technical Field

[0001] The present application relates to the field of HUD film production equipment, and in particular to a HUD film laminating device and a HUD film laminating method applied to the HUD film laminating device. Background Art

[0002] In the prior art, the HUD film laminating equipment includes an upper clamp and a lower clamp. The end wall of the lower clamp opposite to the upper clamp is used to place the substrate, and the end wall of the upper clamp opposite to the lower clamp is used to place the film. The HUD film laminating equipment is used to accurately laminate the film onto the substrate.

[0003] When the distance between the upper clamp and the lower clamp is less than or equal to the height of the worker, the worker needs to bend down to place the film on the upper clamp. It is difficult for the worker to accurately place the film in the preset area of ​​the upper clamp, which causes the worker to adjust the position of the film, thereby reducing the efficiency of placing the film on the upper clamp and reducing the production efficiency of the HUD film.

[0004] On the other hand, when the distance between the upper clamp and the lower clamp is greater than the height of the worker, the worker needs to raise both hands to place the film on the upper clamp. After the worker works for a long time, the worker's work efficiency is reduced, thereby reducing the efficiency of placing the film on the upper clamp, and further reducing the production efficiency of the HUD film. Summary of the invention

[0022] By adopting the above technical solution, the substrate and the carrier film are adhered and matched to keep the substrate in a fixed position relative to the lower clamp, thereby preventing the substrate from deviating from the preset position and causing the film to fail to adhere to the substrate. In addition, when the carrier film is stretched to maintain the carrier film in a taut state, the worker drives the clamping drive assembly to drive the clamping member to move close to the carrier film to clamp the carrier film, thereby preventing the carrier film from shrinking and causing wrinkles in the area of ​​the carrier film used to adhere to the substrate, preventing the substrate from failing to adhere to the carrier film flatly, and preventing the film from failing to adhere to the substrate completely, thereby improving the product quality of the HUD film.

[0034] The following is combined with Figure 1-Figure 10 This application is described in further detail.

[0035] The embodiment of the present application discloses a HUD (Head-Up Display) film laminating device 100 .

[0036] Reference Figure 1 , Figure 3 and Figure 4According to the embodiment of the present application, the HUD film laminating device 100 includes: a mounting frame 1, a fixture assembly 2, and a lifting and flipping mechanism 3. The fixture assembly 2 includes an upper fixture 21 and a lower fixture 22, the lower fixture 22 is fixedly connected to the mounting frame 1, the upper fixture 21 is movably arranged on the mounting frame 1, the upper fixture 21 and the lower fixture 22 are opposite to each other and suitable for abutment, the upper fixture 21 has a first placement wall 211 opposite to the lower fixture 22, and the lower fixture 22 has a second placement wall 221 suitable for being opposite to the upper fixture 21. Specifically, along the height direction of the HUD film laminating device 100, in Figure 4 In the embodiment shown, the first placement wall 211 refers to the lower end wall of the upper fixture 21, and the second placement wall 221 refers to the upper end wall of the lower fixture 22. The first placement wall 211 is used to place the film, and the second placement wall 221 is used to place the substrate. The upper fixture 21 and the lower fixture 22 are stopped so that the film adheres to the substrate. The height direction of the HUD film bonding device 100 can be referred to as Figure 4 The up and down directions in .

[0037] In some specific embodiments, the lower end wall of the upper clamp 21 is provided with a receiving groove, the bottom wall of the receiving groove is constructed as a first placing wall 211, the upper end wall of the lower clamp 22 is provided with a placing protrusion, and the placing protrusion protrudes toward the upper clamp 21, and the top wall of the placing protrusion is constructed as a second placing wall 221. When the upper clamp 21 and the lower clamp 22 are stopped, the second placing wall 221 extends into the receiving groove to allow the diaphragm to adhere to the substrate.

[0038] The upper clamp 21 has a first position state and a second position state relative to the lower clamp 22. When the upper clamp 21 is in the first position state, the first placement wall 211 and the second placement wall 221 are arranged opposite and parallel to each other. When the upper clamp 21 and the lower clamp 22 are stopped, the film located on the first placement wall 211 adheres to the substrate located on the second placement wall 221.

[0039] When the upper clamp 21 is in the second position, the first placement wall 211 and the second placement wall 221 are arranged back to back. Specifically, in the second position, the upper clamp 21 rotates. When the rotation angle of the upper clamp 21 relative to the lower clamp 22 is greater than 0° and less than 180°, there is an angle between the first placement wall 211 and the second placement wall 221. When the rotation angle of the upper clamp 21 relative to the lower clamp 22 is equal to 180°, the first placement wall 211 is located on the side of the upper clamp 21 away from the lower clamp 22 and is arranged parallel to the second placement wall 221.

[0040] By driving the upper clamp 21 to rotate so that the upper clamp 21 is in the second position, the first placement wall 211 is opposite to the worker, and the worker does not need to bend over or raise both hands to place the film on the first placement wall 211, thereby improving the efficiency of placing the film on the upper clamp 21.

[0041] The lifting and flipping mechanism 3 includes a pivot shaft 31, which is connected to the side wall of the upper clamp 21. When the pivot shaft 31 is driven, it drives the upper clamp 21 to switch between a first position state and a second position state around the central axis of the pivot shaft 31, and drives the upper clamp 21 to move closer to or away from the lower clamp 22.

[0042] Specifically, first, the upper clamp 21 is driven to move away from the lower clamp 22 by driving the pivot shaft 31. When the upper clamp 21 moves away from the lower clamp 22 to a preset position, the upper clamp 21 is driven to rotate by driving the pivot shaft 31 to switch the upper clamp 21 from the first position state to the second position state. When the upper clamp 21 is in the second position state, the worker places the film on the first placement wall 211. After the film is placed on the first placement wall 211, the upper clamp 21 is driven to rotate by driving the pivot shaft 31 to switch the upper clamp 21 from the second position state to the first position state. Then, the upper clamp 21 is driven to move close to the lower clamp 22 by driving the pivot shaft 31 to stop the upper clamp 21 and the lower clamp 22, thereby achieving the technical effect of adhering the film to the substrate.

[0043] In some specific embodiments, the pivot shaft 31 can be connected to a motor, which drives the pivot shaft 31 to drive the upper clamp 21 to rotate. The motor is connected to a cylinder, which drives the motor to drive the upper clamp 21 to move closer to or away from the lower clamp 22.

[0044] In some other specific embodiments, the pivot shaft 31 may pass through the output end of the cylinder and be pivotally connected to the pivot end of the cylinder. The cylinder drives the pivot shaft 31 to drive the upper clamp 21 to move closer to or away from the lower clamp 22 .

[0045] Thus, the upper clamp 21 is driven to move away from the lower clamp 22 by driving the pivot shaft 31, and the upper clamp 21 is driven to switch from the first position to the second position, so that the first placement wall 211 is opposite to the worker, and the upper clamp 21 is driven to switch from the second position to the first position by driving the pivot shaft 31, and the upper clamp 21 is driven to move close to the lower clamp 22, so that the upper clamp 21 and the lower clamp 22 are stopped. Compared with the prior art, the worker does not need to bend down or raise both hands to place the film on the first placement wall 211, thereby improving the efficiency of placing the film on the upper clamp 21, and further improving the production efficiency of the HUD film.

[0046] Reference Figure 2 , Figure 4 and Figure 5In some embodiments of the present application, the lifting and flipping mechanism 3 also includes a lifting component 32, a flipping component 33 and a stop component 34. The flipping component 33 includes a driving rack 332 and a driving gear 331. The driving gear 331 is sleeved on the outside of the pivot shaft 31 and fixedly connected to the pivot shaft 31. The driving rack 332 is arranged on the mounting frame 1, and the driving rack 332 is arranged opposite to the driving gear 331. The driving gear 331 is suitable for meshing with the driving rack 332. Specifically, only a partial area of ​​the driving rack 332 is provided with meshing teeth, and the meshing teeth are suitable for meshing with the driving gear 331. When the driving gear 331 moves along the driving rack 332, it drives the pivot shaft 31 to rotate around the central axis of the pivot shaft 31.

[0047] Specifically, when the driving gear 331 moves along the driving rack 332 to the area where the driving rack 332 is provided with meshing teeth, the driving gear 331 meshes with the driving rack 332, and the driving rack 332 drives the driving gear 331 through the meshing teeth to drive the pivot shaft 31 to rotate, so that the pivot shaft 31 drives the upper clamp 21 to switch between the first position state and the second position state.

[0048] When the driving gear 331 moves away from the lower clamp 22 and enters the area where the driving rack 332 is provided with meshing teeth, the driving rack 332 drives the upper clamp 21 to rotate through the driving gear 331 and the pivot shaft 31, so that the upper clamp 21 can be switched from the first position state to the second position state. When the driving gear 331 moves closer to the lower clamp 22 and enters the area where the driving rack 332 is provided with meshing teeth, the driving rack 332 drives the upper clamp 21 to rotate through the driving gear 331 and the pivot shaft 31, so that the upper clamp 21 can be switched from the second position state to the first position state.

[0049] It should be noted that the designer controls the rotation angle of the upper clamp 21 by adjusting the number of meshing teeth on the driving rack 332 .

[0050] The lifting assembly 32 is disposed on the mounting frame 1 , and is connected and cooperated with the pivot shaft 31 . The lifting assembly 32 is used to drive the pivot shaft 31 to drive the upper clamp 21 to move closer to or away from the lower clamp 22 , and to make the driving gear 331 move along the driving rack 332 .

[0051] In some specific embodiments, the lifting assembly 32 may include a cylinder, and the pivot shaft 31 may pass through the output end of the cylinder and be pivotally connected to the pivot end of the cylinder. The cylinder drives the pivot shaft 31 to drive the upper clamp 21 to move closer to or away from the lower clamp 22.

[0052] In other specific embodiments, the lifting assembly 32 may include a traction rope, a fixed pulley and a motor. The fixed pulley is located above the upper clamp 21. One end of the traction rope is movably mounted on the outer wall of the pivot shaft 31, and the other end of the traction rope passes around the fixed pulley and is fixedly connected to the motor. The motor drives the upper clamp 21 to move closer to or away from the lower clamp 22 through the traction rope and the pivot shaft 31.

[0053] The stop assembly 34 is arranged on the pivot shaft 31 and is used to limit or unlock the upper clamp 21 in the first position state and / or the second position state. By arranging the stop assembly 34 on the pivot shaft 31, when the pivot shaft 31 is driven to rotate by the driving rack 332, the stop assembly 34 unlocks the upper clamp 21, so that the pivot shaft 31 drives the upper clamp 21 to switch between the first position state and the second position state. When the pivot shaft 31 is not driven by the driving rack 332, the stop assembly 34 limits the upper clamp 21 to the first position state or the second position state, thereby preventing the upper clamp 21 from rotating, preventing the worker from being unable to place the diaphragm on the first placement wall 211, or preventing the upper clamp 21 from colliding with the lower clamp 22 to cause damage to the upper clamp 21 and the upper clamp 21, thereby improving the working reliability of the HUD film bonding equipment 100.

[0054] Reference Figure 4 and Figure 5 In some embodiments of the present application, the lifting assembly 32 includes a first driving member 321, which is connected to the pivot shaft 31. The first driving member 321 is used to drive the pivot shaft 31 to move closer to or away from the lower clamp 22. Along the height direction of the HUD film bonding device 100, in some specific embodiments, the first driving member 321 can be arranged above the pivot shaft 31, and in other specific embodiments, the first driving member 321 can be arranged below the pivot shaft 31.

[0055] Specifically, the pivot shaft 31 can pass through the output end of the first driving member 321 and be pivotally connected to the pivot end of the first driving member 321. The first driving member 321 drives the pivot shaft 31 to drive the upper clamp 21 to move closer to or away from the lower clamp 22, thereby achieving the technical effect of the pivot shaft 31 driving the upper clamp 21 to move closer to or away from the lower clamp 22.

[0056] In some specific embodiments, the first driving member 321 may be a cylinder, but the present application is not limited thereto, and the first driving member 321 may also be a hydraulic cylinder or the like.

Specifically, along the height direction of the HUD film bonding device 100, the first driving member 321 is arranged above the pivot shaft 31, and the output end of the first driving member 321 is connected and cooperated with the upper end wall of the stop member 341. The stop member 341 and the friction member 342 are both movably mounted on the outer peripheral wall of the pivot shaft 31, and the friction member 342 is located between the stop member 341 and the pivot shaft 31. Specifically, the pivot shaft 31 is pivotally connected to the stop member 341, and the friction member 342 is suitable for moving along the axial direction of the pivot shaft 31.

[0058] Furthermore, along the axial direction of the pivot shaft 31, the stop member 341 has a first side wall 3411 and a second side wall 3412 relative to each other. Specifically, the side wall of the stop member 341 opposite to the driving gear 331 is constructed as the first side wall 3411, and the side wall of the stop member 341 away from the driving gear 331 is constructed as the second side wall 3412. The first side wall 3411 is opposite to the driving gear 331 and is provided with a stop portion 3413. The stop portion 3413 is provided with a stop hole 3414, and the stop hole 3414 passes through the stop portion 3413. The friction member 342 is arranged in the stop hole 3414. When the friction member 342 is driven, the friction member 342 is suitable for extending into or moving out of the stop hole 3414.

[0059] Furthermore, the shapes of the anti-rotation hole 3414 and the friction member 342 are both constructed to be conical, and along the direction from the driving gear 331 to the stop member 341, the cross-sectional area of ​​the friction member 342 and the diameter of the anti-rotation hole 3414 gradually increase.

[0060] The rotation of the pivot shaft 31 is limited by the frictional engagement between the friction member 342 and the inner circumferential wall of the stop hole 3414. Specifically, when the friction member 342 is driven to extend into the stop hole 3414, the outer circumferential wall of the friction member 342 and the inner circumferential wall of the stop hole 3414 are frictionally engaged so that the friction member 342 and the stop portion 3413 are locked and engaged, thereby limiting the rotation of the pivot shaft 31 and limiting the upper clamp 21 to be in the first position state or the second position state. When the friction member 342 is driven to move out of the stop hole 3414, the outer peripheral wall of the friction member 342 is separated from the inner peripheral wall of the stop hole 3414, and the pivot shaft 31 drives the friction member 342 to rotate around the central axis of the pivot shaft 31. That is to say, when the friction member 342 is driven to move out of the stop hole 3414, the pivot shaft 31 is in a freely rotatable state, and when the friction member 342 is driven to extend into the stop hole 3414, the pivot shaft 31 is in a locked state and the pivot shaft 31 cannot rotate.

[0061] A driving protrusion 3311 is provided on the side wall of the driving gear 331 close to the stop friction member 342. The driving protrusion 3311 protrudes toward the friction member 342. A driving groove 3421 opposite to the driving protrusion 3311 is provided on the side wall of the friction member 342 close to the driving gear 331. The driving protrusion 3311 extends into the driving groove 3421, and the driving protrusion 3311 stops at the bottom of the driving groove 3421.

[0062] In some specific embodiments, the shapes of the driving protrusion 3311 and the driving groove 3421 can both be constructed to be hemispherical, and the diameter of the open end of the driving groove 3421 is slightly larger than the maximum diameter of the driving protrusion 3311. When the driving protrusion 3311 extends into the driving groove 3421, the driving protrusion 3311 stops at the bottom wall of the driving groove 3421, and the driving protrusion 3311 is separated from the inner wall of the driving groove 3421.

[0063] When the driving gear 331 rotates, the driving protrusion 3311 moves away from the driving groove 3421 to make the friction member 342 move away from the driving gear 331 . The elastic member 343 can be elastically deformed and arranged between the friction member 342 and the stop member 341 . The elastic member 343 is used to drive the friction member 342 to move closer to the driving gear 331 .

[0064] Specifically, the driving protrusion 3311 moves around the central axis of the pivot shaft 31 away from the bottom wall of the driving groove 3421, and the driving protrusion 3311 moves close to the inner side wall of the driving groove 3421. When the driving protrusion 3311 abuts against the inner side wall of the driving groove 3421, the driving protrusion 3311 drives the friction member 342 to move away from the driving gear 331. In other words, the driving protrusion 3311 drives the friction member 342 to move out of the rotation-stopping hole 3414. When the friction member 342 is far away from the driving gear 331, the driving protrusion 3311 drives the friction member 342 to move out of the rotation-stopping hole 3414. When the driving gear 331 moves, the friction member 342 drives the elastic member 343 to compress and deform. When the elastic member 343 is compressed to a preset length, the elastic force applied by the elastic member 343 to the friction member 342 is equal to the thrust applied by the driving protrusion 3311 to the friction member 342. That is to say, the position of the friction member 342 relative to the stop portion 3413 remains unchanged, and the friction member 342 has not completely disengaged from the stop portion 3413, and the driving protrusion 3311 has not moved out of the driving groove 3421.

[0065] When the driving gear 331 stops rotating, the elastic member 343 applies an elastic force toward the driving gear 331 to the friction member 342 so that the friction member 342 moves closer to the driving gear 331 , that is, the friction member 342 extends into the stop hole 3414 , and the driving protrusion 3311 moves along the inner wall of the driving groove 3421 close to the driving groove 3421 .

[0066] When the driving gear 331 rotates, the driving gear 331 drives the friction member 342 to move out of the stop hole 3414 through the driving protrusion 3311 and the driving groove 3421 to unlock the pivot shaft 31. The pivot shaft 31 can drive the upper clamp 21 to switch between the first position state and the second position state. When the driving gear 331 stops rotating, the elastic member 343 drives the friction member 342 to extend into the stop hole 3414. The friction member 342 and the stop hole 3414 frictionally cooperate to lock the pivot shaft 31, thereby preventing the upper clamp 21 from rotating, preventing the worker from being unable to place the diaphragm on the first placement wall 211, or preventing the upper clamp 21 from colliding with the lower clamp 22, resulting in damage to the upper clamp 21 and the upper clamp 21, thereby improving the working reliability of the HUD film bonding equipment 100.

[0067] In some specific embodiments, the elastic member 343 may be a spring, but the present application is not limited thereto, and the elastic member 343 may also be a tension spring or the like.

[0068] Reference Figure 2 , Figure 4 and Figure 8 In some embodiments of the present application, the lifting assembly 32 also includes a guide member 322, which is arranged on the mounting frame 1, and the guide member 322 is arranged opposite to the stop member 341, and a guide rail 3221 is arranged on the side wall of the guide member 322 opposite to the stop member 341, and the guide rail 3221 is extended along the height direction of the HUD film bonding device 100, and a guide portion 3415 is arranged on the side wall of the stop member 341 opposite to the guide member 322, and the guide portion 3415 is guided and matched with the guide rail 3221.

[0069] When the first driving member 321 drives the upper clamp 21 to move closer to or away from the lower clamp 22 through the stop member 341 and the pivot shaft 31, the stop member 341 can be prevented from deviating from the preset motion trajectory through the guiding cooperation between the guide part 3415 and the guide rail 3221, thereby preventing the upper clamp 21 from deviating from the preset motion trajectory and causing the upper clamp 21 to be unable to stop with the lower clamp 22, thereby improving the working reliability of the HUD film bonding device 100.

[0070] Further, the driving rack 332 may be disposed on a side wall of the guide member 322 opposite to the driving gear 331 .

[0071] Reference Figure 1 , Figure 3 and Figure 4In some embodiments of the present application, the HUD film bonding device 100 may further include: a clamping mechanism 4, wherein the end wall of the lower clamp 22 close to the upper clamp 21 is provided with a carrier film 222, and the substrate is suitable for adhering to the carrier film 222, and the substrate and the carrier film 222 are adhered and cooperated to maintain the substrate in a fixed position relative to the lower clamp 22, thereby preventing the substrate from deviating from the preset position and causing the film to fail to adhere to the substrate.

[0072] The clamping mechanism 4 is arranged on the mounting frame 1, and the clamping mechanism 4 includes a clamping member 41 and a clamping drive assembly 42. The clamping member 41 is arranged on the outer side of the lower clamp 22 and is arranged opposite to the supporting film 222. The clamping member 41 is used to clamp the supporting film 222. The clamping drive assembly 42 is connected and cooperated with the clamping member 41. The clamping drive assembly 42 is used to drive the clamping member 41 to move closer to or away from the supporting film 222.

[0073] Specifically, when the carrier film 222 is stretched so that the carrier film 222 is maintained in a taut state, the worker drives the clamping drive assembly 42 to drive the clamping member 41 to move close to the carrier film 222 to clamp the carrier film 222, thereby preventing the carrier film 222 from shrinking and causing wrinkles in the area of ​​the carrier film 222 used to adhere to the substrate, preventing the substrate from being unable to adhere flatly to the carrier film 222, and preventing the film from being unable to completely adhere to the substrate, thereby improving the product quality of the HUD film.

[0074] Furthermore, clamping the carrier film 222 by the clamping member 41 can prevent the carrier film 222 from deviating from a preset position, and can prevent the substrate from failing to adhere to the carrier film 222 .

[0075] Reference Figure 4 and Figure 7 In some embodiments of the present application, the clamping drive assembly 42 includes a second drive member 421 and a lead screw 422, the clamping member 41 is provided with a transmission hole 411, and the inner peripheral wall of the transmission hole 411 is provided with a transmission thread. Specifically, along the height direction of the HUD film bonding device 100, the transmission hole 411 is provided on the side wall of the lower end of the clamping member 41 opposite to the supporting film 222, and the transmission hole 411 passes through the clamping member 41.

[0076] In addition, the lead screw 422 passes through the transmission hole 411 and is meshed with the transmission thread of the transmission hole 411. The second driving member 421 is connected and cooperated with the lead screw 422. The second driving member 421 is used to drive the lead screw 422 to rotate around the central axis of the lead screw 422, so that the lead screw 422 drives the clamping member 41 to move closer to or away from the supporting film 222.

[0077] In some specific embodiments, when the clamping member 41 is required to clamp the carrier film 222, the second driving member 421 drives the lead screw 422 to rotate clockwise, and the lead screw 422 drives the clamping member 41 to move close to the carrier film 222, thereby achieving the technical effect that the clamping member 41 moves close to the carrier film 222 and clamps the carrier film 222. When the carrier film 222 needs to be released, the second driving member 421 drives the lead screw 422 to rotate counterclockwise, and the lead screw 422 drives the clamping member 41 to move away from the carrier film 222, thereby achieving the technical effect that the clamping member 41 is separated from the carrier film 222.

[0078] In some specific embodiments, the second driving member 421 may be a motor, but the present application is not limited thereto. The second driving member 421 may also be a hydraulic motor or the like.

[0079] Reference Figure 1 and Fig. 9 In some embodiments of the present application, there are multiple clamping members 41 and multiple clamping drive assemblies 42, and the multiple clamping members 41 and multiple clamping drive assemblies 42 are arranged in sequence along the circumferential direction of the lower clamp 22, and the multiple clamping members 41 and multiple clamping drive assemblies 42 are arranged one by one.

[0080] Specifically, by providing a plurality of clamping members 41 and a plurality of clamping drive components 42, the plurality of clamping drive components 42 simultaneously drive the corresponding clamping members 41 to move close to the carrier film 222, thereby achieving the technical effect of clamping the carrier film 222 at multiple angles, avoiding shrinkage and deformation of the carrier film 222 due to partial areas of the carrier film 222 not being clamped, avoiding wrinkles in partial areas of the carrier film 222, and further improving the product quality of the HUD film.

[0081] Furthermore, the two clamping members 41 opposite to each other at 180° can be driven by a clamping drive assembly 42. Specifically, the lead screw 422 is provided with two sections of meshing threads with different rotation directions. The lead screw 422 passes through the transmission holes 411 of the two clamping members 41 opposite to each other at 180°. One section of the two meshing threads with different rotation directions is meshed and connected with the transmission thread of one transmission hole 411, and the other section of the two meshing threads with different rotation directions is meshed and connected with the transmission thread of another transmission hole 411. When the second driving member 421 drives the lead screw 422 to rotate, the lead screw 422 simultaneously drives the two clamping members 41 to move closer to or away from the supporting film 222. Such a configuration can reduce the number of second driving members 421, thereby reducing the manufacturing cost of the HUD film bonding device 100.

[0082] Reference Figure 3 and Figure 4In some embodiments of the present application, the upper clamp 21 and the lower clamp 22 are both provided with a plurality of air holes 223, and the plurality of air holes 223 are spaced apart along the radial direction of the HUD film bonding device 100, and the plurality of air holes 223 all penetrate the upper clamp 21 and the lower clamp 22, one end of the air hole 223 provided on the upper clamp 21 is communicated with the first placement wall 211, and the other end of the air hole 223 provided on the upper clamp 21 is communicated with the first exhaust device, one end of the air hole 223 provided on the lower clamp 22 is communicated with the second placement wall 221, and the other end of the air hole 223 provided on the lower clamp 22 is communicated with the second exhaust device.

[0083] In addition, the first exhaust device adsorbs the diaphragm to the first placement wall 211 through the air hole 223, and the second exhaust device adsorbs the substrate to the second placement wall 221 through the air hole 223. Specifically, when the HUD film bonding device 100 is needed to adhere the diaphragm to the substrate, the worker places the diaphragm on the first placement wall 211, and places the substrate on the second placement wall 221, and exhausts air through the first exhaust device to generate negative pressure in the air hole 223 provided on the upper clamp 21, so as to adsorb and fix the diaphragm on the first placement wall 211, and exhausts air through the second exhaust device to generate negative pressure in the air hole 223 provided on the lower clamp 22, so as to adsorb and fix the substrate on the second placement wall 221, so as to avoid the diaphragm from falling off the upper clamp 21 and the substrate from falling off the lower clamp 22 as much as possible, thereby improving the working reliability of the HUD film bonding device 100.

[0084] In some specific embodiments, the first exhaust device and the second exhaust device may be the same exhaust device, and the exhaust device may be a vacuum pump, but the present application is not limited thereto, and the exhaust device may also be a centrifugal fan, etc.

[0085] Based on this, the present application further discloses a HUD film laminating method, which is applicable to the HUD film laminating device described in the above embodiment. Fig.10 As shown, the HUD film bonding method according to the embodiment of the present application includes the following steps: S1. Drive the upper clamp to move away from the lower clamp, and drive the upper clamp to rotate around the central axis of the pivot shaft, so that the first placement wall and the second placement wall are opposite to each other. Specifically, the first driving member drives the upper clamp and the driving gear to move away from the lower clamp through the stop member and the pivot shaft. When the driving gear enters the area where the driving rack is provided with meshing teeth, the driving rack drives the driving gear to rotate, and the driving gear drives the friction member to move out of the stop hole through the driving protrusion and the driving groove to unlock the pivot shaft. The driving gear drives the pivot shaft to drive the upper clamp to rotate, so that the first placement wall and the second placement wall are opposite to each other, and the first placement wall is opposite to the worker.

[0086] Furthermore, when the driving gear stops rotating, the elastic member drives the friction member to extend into the anti-rotation hole, and the friction member and the anti-rotation hole are frictionally matched to lock the pivot shaft.

[0087] S2. Fix the film on the first placement wall and fix the substrate on the second placement wall. Specifically, the worker places the film on the first placement wall by hand and places the substrate on the second placement wall by hand.

[0088] S3. Drive the upper clamp to rotate around the central axis of the pivot shaft so that the first placement wall and the second placement wall are opposite to each other, and drive the upper clamp to move close to the lower clamp so that the upper clamp and the lower clamp are stopped. Specifically, first, the first driving member drives the upper clamp and the driving gear to move close to the lower clamp through the stop member and the pivot shaft. When the driving gear enters the area where the driving rack is provided with meshing teeth again, the driving rack drives the driving gear to rotate. The driving gear drives the friction member to move out of the stop hole through the driving protrusion and the driving groove to unlock the pivot shaft. The driving gear drives the pivot shaft to drive the upper clamp to rotate so that the first placement wall and the second placement wall are opposite to each other. Then the first driving member drives the upper clamp and the driving gear to move close to the lower clamp through the stop member and the pivot shaft so that the upper clamp and the lower clamp are stopped.

[0089] Furthermore, when the driving gear stops rotating, the elastic member drives the friction member to extend into the anti-rotation hole, and the friction member and the anti-rotation hole are frictionally matched to lock the pivot shaft.

[0090] S4, controlling the upper clamp and the lower clamp to stop, so that the diaphragm adheres to the substrate. Specifically, the first driving member drives the upper clamp to move closer to the lower clamp through the stop member and the pivot shaft, and the upper clamp and the lower clamp stop, so that the diaphragm adheres to the substrate.

[0091] S5. Drive the upper clamp to move away from the lower clamp. Specifically, the first driving member drives the upper clamp to move away from the lower clamp through the stop member and the pivot shaft, and the worker takes out the processed substrate from the second placement wall.

[0092] Therefore, through the HUD film bonding method of the embodiment of the present application, the HUD film bonding method can be used to drive the upper clamp and the driving gear to move away from the lower clamp through the first driving member through the stop member and the pivot shaft, and drive the driving mechanism gear to rotate through the driving rack, and the driving gear drives the pivot shaft to drive the upper clamp to rotate, so that the first placement wall and the second placement wall are opposite to each other, and the first placement wall is opposite to the worker. The worker does not need to bend over or raise his hands to place the film on the first placement wall, thereby improving the efficiency of placing the film on the upper clamp, and then improving the production efficiency of the HUD film.

[0093] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
