Description

Technical Field

[0002] Electronic products have gradually developed into ergonomically rounded shapes, and electronic products with glass on both the front and back have emerged. For aesthetics and a more comfortable feel, some electronic products also use glass on the back, and the inner surface of the glass used on the back of electronic products usually needs special treatment, such as sticking a layer of film with a certain color or pattern. In order to reduce the internal space occupied by the mobile phone, the inner surface of the glass on the back of the electronic product is also set to a curved shape with the same bending direction as the outer surface, that is, the inner surface of the glass back is a concave surface. When applying a film on the concave surface of the glass, the position accuracy of the film and the glass is very high, and it is easy to have bubbles or wrinkles in the edge bonding area.

[0044] Please refer to Figures 1 to 19 The present invention proposes a glass film pasting device, including a glass positioning mechanism 100 and a flipping and pasting mechanism 200; the glass positioning mechanism 100 includes a glass positioning plate 110, a first driving mechanism 120 and a glass positioning push block 130 located around the glass positioning plate 110; the first driving mechanism 120 is used to drive the glass positioning push block 130 to move toward the glass positioning plate 110; the flipping and pasting mechanism 200 includes two glass positioning mechanisms 100 arranged back to back; both of the two glass positioning mechanisms 100 have a pasting position and a glass loading / unloading position, and when one of the glass positioning mechanisms 100 rotates to the pasting position with the flipping and pasting mechanism 200, the other glass positioning mechanism 100 is located at the glass loading / unloading position.

[0045] The flipping and laminating mechanism 200 used in the present invention comprises a rotating arm 210 that can rotate in a vertical plane and a base 220 that drives the rotating arm 210 to rotate. The end of the rotating arm 210 is provided with a first cavity 210a and a second cavity 210b opposite to the first cavity 210a. The two glass positioning mechanisms 100 are respectively arranged in the first cavity 210a and the second cavity 210b. The rotating arm 210 can rotate between 0 degrees and 180 degrees, and the rotating arm 210 has two laminating positions, which correspond to the 0 degree position and the 180 degree position of the rotating arm 210 respectively. The rotating arm 210 has a rotating shaft 211, and a motor is arranged in the base 220. The rotating shaft 211 is connected to the motor and rotates under the drive of the motor.

[0046] When the rotating arm 210 rotates to the 0 degree position, the opening direction of the first cavity 210a faces downward, and the bottom of the first cavity 210a is the film to be bonded. At this time, the glass positioning mechanism 100 in the first cavity 210a clamps the positioned glass plate and bonds it to the film, and the glass positioning mechanism 100 in the first cavity 210a is in the bonding position; at the same time, the opening direction of the second cavity 210b faces upward, and the glass positioning mechanism 100 in the second cavity 210b loads the glass plate or unloads the glass plate after the film is bonded. At this time, the glass positioning mechanism 100 in the second cavity 210b is in the loading position and also the unloading position.

[0047] When the rotating arm 210 rotates to a position of 180 degrees, the opening direction of the second cavity 210b faces downward, and the bottom of the second cavity 210b is the film to be bonded. At this time, the glass positioning mechanism 100 in the second cavity 210b clamps the positioned glass plate and bonds it to the film, and the glass positioning mechanism 100 in the second cavity 210b is in a bonding position; at the same time, the opening direction of the first cavity 210a faces upward, and the glass positioning mechanism 100 in the first cavity 210a loads the glass plate or unloads the glass plate after the film is bonded. At this time, the glass positioning mechanism 100 in the first cavity 210a is in a loading position and also a unloading position.

[0048] By flipping the laminating mechanism 200, the present invention can realize that the laminating process of the film and the glass plate and the loading / unloading process of the glass plate do not interfere with each other and are carried out synchronously, thereby improving the laminating rate of the equipment. The specific steps of the laminating process are as follows:

[0049] Step 1: Flip the laminating mechanism to the 0 degree position or reset it to the 0 degree position, so that the second cavity 210b is at the loading position, and perform the glass plate loading operation;

[0050] Step 2: The glass positioning mechanism 100 in the second cavity 210b positions the glass plate;

[0051] Step 3: The flipping and laminating mechanism 200 flips 180 degrees to a 180 degree position; at this time, the second cavity 210b opens downward and is in a laminating position, and the first cavity 210a opens upward and is in a loading position;

[0052] Step 4: The glass plate and the film are bonded at the bonding position of the glass positioning mechanism 100 in the second cavity 210b; at the same time, the glass plate is loaded at the loading station in the first cavity 210a, and after the loading is completed, the glass positioning mechanism 100 in the first cavity 210a positions the glass plate;

[0053] Step 5: The flipping and laminating mechanism 200 flips 180 degrees in the opposite direction and returns to the 0 degree position; at this time, the first cavity 210a opens downward and is in the laminating position, and the second cavity 210b opens upward and is in the unloading position;

[0054] Step 6: The glass plate and the film are bonded at the bonding position in the first cavity 210a; at the same time, the bonded glass plate is unloaded at the unloading position in the second cavity 210b, and the glass plate is loaded after unloading, and the glass positioning mechanism 100 in the second cavity 210b positions the glass plate after loading;

[0055] Step 7: The flipping and laminating mechanism 200 flips 180 degrees to a 180-degree position; at this time, the second cavity 210b opens downward and is in a laminating position, and the first cavity 210a opens upward and is in a material unloading position;

[0056] Step 8: The glass plate and the film are bonded at the bonding position in the second cavity 210b; at the same time, the unloading station in the first cavity 210a unloads the bonded glass plate, and after unloading, the glass plate is loaded, and after loading, the glass positioning mechanism 100 in the first cavity 210a positions the glass plate;

[0057] Step 9: Repeat Step 5 to Step 8.

[0058] It should be noted that in order to reduce the possibility of bubbles between the membrane and the glass plate during the bonding process and to minimize the impact of possible bubbles on the finished product, it is a conventional design in the art to set a vacuum mechanism to put the bonding station in a vacuum state. The present invention does not improve the vacuum mechanism, and the present invention will not elaborate on this.

[0059] like Figures 5 to 8 As shown, in order to ensure the accuracy of the position when the glass is positioned, the glass positioning plate 110 in the present invention is rectangular; the glass positioning push block 130 includes a longitudinal glass positioning push block 1301 arranged in the length direction of the glass positioning plate 110, and a transverse glass positioning push block 1302 arranged in the width direction of the glass positioning plate 110. The glass positioning plate 110 is provided with a first negative pressure hole 111, and the first negative pressure hole 111 is used to adsorb the glass plate.

[0060] The first driving mechanism 120 includes a longitudinal driving component and a transverse driving component 121; the transverse driving component 121 includes a longitudinal driving motor 1210, a first inclined push plate 1211, two second inclined push plates 1212 and a transverse guide rail 1213; the first inclined push plate 1211 is connected to the driving shaft of the longitudinal driving motor 1210, and the two second inclined push plates 1212 are respectively connected to the transverse glass positioning push block 1302; the two second inclined push plates 1212 are arranged on the transverse guide rail 1213 and along the transverse Move toward the guide rail 1213; the first inclined push plate 1211 has two symmetrical first inclined push surfaces, and the two second inclined push plates 1212 have two symmetrical second inclined push surfaces, and the two second inclined push surfaces cooperate with the two first inclined push surfaces, so that when the longitudinal driving motor 1210 pushes the first inclined push plate 1211, the first inclined push plate 1211 drives the two second inclined push plates 1212 to move toward each other, thereby driving the transverse glass positioning push block 1302 to move toward each other, so as to position and clamp the glass plate in the width direction of the glass plate.

[0061] The present invention adopts the method of inclined surface pushing to realize that the glass plate can be positioned in the width direction by using one driving motor. When the first inclined push plate 1211 moves to the right under the action of the longitudinal driving motor 1210, the two first inclined surfaces push the two second inclined surfaces to drive the two second inclined push plates 1212 to approach each other along the transverse guide rail 1213. The two first inclined surfaces, the two second inclined surfaces and the two second transverse glass positioning push blocks 1302 of the present invention are symmetrically arranged, so that when the longitudinal driving motor 1210 drives the first inclined push plate 1211 to move, the first inclined push plate 1211 drives the two second inclined push plates 1212 to move in the opposite direction synchronously, and the center line of the two second inclined push plates 1212 approaching each other coincides with the bisector of the angle formed by the two first inclined push surfaces, that is, the center line of the transverse position of the glass plate coincides with the bisector of the angle formed by the two first inclined push surfaces, and then the transverse relative position of the first inclined push plate 1211 and the glass positioning plate 110 can be adjusted to control the transverse position of the glass plate relative to the glass positioning plate 110.

[0062] The longitudinal drive assembly is used to drive the longitudinal glass positioning push block 1301. The longitudinal drive assembly adopts the same drive structure and drive mode as the transverse drive assembly 121, and can uniquely determine the longitudinal center position of the glass plate. The longitudinal drive assembly and the transverse drive assembly 121 avoid each other to avoid interference. The drive motor in the present invention can also be replaced by a drive cylinder to play a linear drive role. It should be understood that such replacement should also fall within the scope of protection of the present invention.

[0063] The center position of the glass plate positioned by the glass positioning mechanism 100 of the present invention does not change with the movement of the glass positioning push block 130. Therefore, the glass positioning mechanism 100 adopted by the present invention can dynamically adapt to glass plates of different sizes. Without adjusting the glass positioning mechanism 100, it can ensure that the positions of glass plates of different sizes are accurately positioned at the set positions.

[0064] In a specific embodiment of the present invention, the first inclined surface and the second inclined surface can be separated laterally. When the longitudinal drive motor 1210 is reset to drive the first inclined push plate 1211 to be reset, the two second inclined push plates 1212 are reset through the elastic return mechanism 140, that is, an elastic return mechanism 140 is also provided between the two second inclined push plates 1212 to reset the two glass positioning push blocks 130 when the longitudinal drive motor 1210 is reset.

[0065] To reduce the friction between the first and second inclined push surfaces, refer to Figure 8 As shown, in another embodiment of the present invention, a cross rail 1214 is provided between the first inclined push surface and the second inclined push surface, and the cross rail 1214 includes a first rail 1214a and a second rail 1214b, wherein the first rail 1214a is fixed to the first inclined push surface, and the second rail 1214b is fixed to the second inclined push surface. The cross rail 1214 is a separate rail, that is, the first rail 1214a can be laterally separated from the second rail 1214b, and the first rail 1214a can push the second rail 1214b to achieve relative sliding of the first rail 1214a with respect to the second rail 1214b, but when the first rail 1214a is reset, it has no pulling effect on the second rail 1214b.

[0066] In other embodiments, the cross rail 1214 may also be an integrated rail, that is, the first rail 1214a has both a pushing and pulling effect on the second rail 1214b, and the first rail 1214a and the second rail 1214b can only slide relative to each other in the length direction, and the two cannot be separated laterally. At this time, when the longitudinal drive motor 1210 resets and drives the first rail 1214a to reset, the first rail 1214a pulls the second rail 1214b, thereby resetting the second rail 1214b. The first rail 1214a and the second rail 1214b are respectively fixed to the first inclined push surface and the second inclined push surface, so when the longitudinal drive motor 1210 is reset, the two horizontal glass positioning push blocks 1302 are synchronously driven to reset. When the cross rail 1214 is an integrated rail, there is no need to set an elastic recovery mechanism between the two second inclined push plates 1212.

[0067] like Figures 9 to 12As shown, when the glass plate is precisely positioned, in order to ensure the accuracy of the bonding between the glass plate and the film, the glass film bonding equipment of the present invention also includes a film positioning mechanism 300, and the film positioning mechanism 300 includes a film positioning plate 310, a second driving mechanism 320 and a film positioning push block 330 located around the film positioning plate 310; the film positioning plate 310 is rectangular, and the length and width of the film positioning plate 310 are respectively the same as the length and width of the film; the film positioning push block 330 is higher than the film positioning plate 310, and the second driving mechanism 320 is used to drive the film positioning push block 330 so that the film positioning push block 330 clamps the film positioning plate 310, and in the process of clamping the film positioning plate 310, pushes the film so that the film overlaps with the film positioning plate 310.

[0068] The size of the membrane positioning plate 310 used in the membrane positioning mechanism 300 of the present invention can be adjusted according to the size of the membrane sheet, so that the size of the membrane positioning plate 310 is always the same as the size of the membrane sheet to be bonded. After the membrane sheet is transported to the membrane positioning plate 310, the second driving mechanism 320 drives the membrane positioning push block 330 to stick to the edge of the membrane positioning plate 310, thereby ensuring that the edge of the membrane sheet is aligned with the edge of the membrane positioning plate 310, thereby ensuring the accuracy of the membrane sheet position.

[0069] The diaphragm itself is made of a relatively soft material. In order to further ensure the consistency between the position of the diaphragm and the position of the membrane positioning plate 310, the present invention further provides a second negative pressure hole 311 on the membrane positioning plate 310. The second negative pressure hole 311 is used to adsorb the diaphragm so that the diaphragm is flatly attached to the membrane positioning plate 310. Of course, the adsorption force of the second negative pressure hole 311 on the diaphragm can be adjusted, and while ensuring the flatness of the diaphragm, it can also ensure that the diaphragm does not deform or wrinkle when it moves on the membrane positioning plate 310 under the push of the membrane positioning push block 330.

[0070] In addition to adopting the method of opening the second negative pressure hole 311 on the membrane positioning plate 310, in other embodiments, the present invention can also ensure the flatness of the diaphragm by adopting a pressing plate 350. Specifically, the membrane positioning mechanism 300 also includes a pressing plate 350, and the pressing plate 350 is arranged above the membrane positioning plate 310 and can move up and down; the edge of the membrane positioning plate 310 is provided with a limiting pillar 360 higher than the membrane positioning plate 310, so that the minimum distance between the pressing plate 350 and the membrane positioning plate 310 is greater than the thickness of the diaphragm. When the pressing plate 350 presses the membrane positioning plate 310 downward, under the limiting action of the limiting pillar 360, the minimum distance between the two, that is, the height of the limiting pillar 360 above the membrane positioning plate 310, is slightly greater than the thickness of the diaphragm, so as to ensure that the diaphragm maintains a smooth movement under the pushing action of the membrane positioning push block 330 to avoid wrinkles or bulges. The height of the limiting pillar 360 can be adjusted so that the minimum spacing can always be slightly larger than the thickness of the diaphragm to adapt to the positioning of diaphragms of different thicknesses. For example, when the thickness of the diaphragm is 0.5 mm, the height of the limiting pillar 360 can be adjusted so that the minimum spacing is between 0.55 mm and 1.5 mm. Furthermore, the minimum spacing is preferably set between 0.7 and 1.0 mm, that is, the protruding height of the limiting pillar 360 is 0.2 mm to 0.5 mm larger than the thickness of the diaphragm.

[0071] The membrane positioning push blocks 330 may be provided in four groups, which are respectively located around the membrane positioning plate 310 , or only two groups may be provided, where the two groups of membrane positioning push blocks 330 are located on two adjacent sides of the membrane positioning plate 310 .

[0072] The second driving mechanism 320 may adopt a plurality of driving motors, so that each driving motor drives a corresponding group of the film positioning push blocks 330 , or may adopt a linkage mechanism, setting a driving motor to synchronously drive all or part of the film positioning push blocks 330 .

[0073] The present invention proposes an embodiment, in which four membrane positioning push blocks 330 are provided, respectively located on the four sides of the membrane positioning push blocks 330, and the second driving mechanism 320 is driven by two driving motors. Specifically, the second driving mechanism 320 includes a longitudinal cylinder 321 and a longitudinal slide rail 322, and a transverse cylinder 323 and a transverse slide rail 324; the longitudinal cylinder 321 is slidably installed on the longitudinal slide rail 322, and the cylinder body and push rod of the longitudinal cylinder 321 are respectively connected to the two longitudinal membrane positioning push blocks 331 located in the length direction of the membrane positioning plate 310; the transverse cylinder 323 is slidably installed on the transverse slide rail 324, and the cylinder body and push rod of the transverse cylinder 323 are respectively connected to the two transverse membrane positioning push blocks 332 located in the width direction of the membrane positioning plate 310.

[0074] The cylinder body of the longitudinal cylinder 321 in this embodiment is slidably disposed on the slide rail and connected to one longitudinal film positioning push block 331; the driving shaft of the longitudinal cylinder 321 is connected to another longitudinal film positioning push block 331. The two longitudinal film positioning push blocks 331 can be moved closer to or farther away from each other under the drive of the longitudinal cylinder 321, and at the same time, the two longitudinal film positioning push blocks 331 and the longitudinal cylinder 321 can slide left and right on the longitudinal slide rail 322 as a whole. In order to ensure that the two longitudinal film positioning push blocks 331 are separated from the film positioning plate 310 when they are reset after clamping the film positioning plate 310, the film positioning mechanism 300 in this embodiment further includes a limit stopper 340, and the limit stopper 340 includes a longitudinal limit stopper 341 and a transverse limit stopper 342. The longitudinal limit stopper 341 is used to limit the maximum distance of the two longitudinal film positioning push blocks 331 away from the film positioning plate 310. The longitudinal limit stopper 341 can be directly set on the outside of the two longitudinal film positioning push blocks 331, or fixedly set on the longitudinal slide rail 322; the transverse limit stopper 342 is used to limit the maximum distance of the two transverse film positioning push blocks 332 away from the film positioning plate 310. The transverse limit stopper 342 can be directly set on the outside of the two longitudinal film positioning push blocks 331, or fixedly set on the transverse slide rail 324.

[0075] In order to make the film positioning mechanism 300 applicable to a variety of film sheets of different sizes and specifications, the edge of the film positioning plate 310 in the present invention is also provided with a correction block, and the correction block is used to correct the size of the film positioning plate 310 so that the size of the film positioning plate 310 is the same as the size of the film sheet. The film positioning plate 310 in this embodiment includes a substrate, the size of the substrate is not greater than the size of the smallest film sheet that can be positioned by the film positioning plate 310; correction plates of different specifications are arranged on the outside of the substrate so that the film positioning plate 310 is applicable to film sheets of different specifications.

[0076] The film thickness is small and it is relatively soft. In order to increase the feeding speed of the film, the glass bonding equipment of the present invention further includes a feeding mechanism 400, which includes a film frame 410 for placing the film, a position sensor 420 for detecting the height of the film, and a lifting mechanism 430 for pushing the film up. The film frame 410 also includes a limiting component. In a specific embodiment, the limiting component is provided with two limiting rods on each side; the lifting mechanism 430 is located on the inner side of the plurality of limiting rods and can move up and down. The position sensor 420 detects the height of the film. When the topmost film is taken away, the lifting mechanism 430 drives the film to move upward by the thickness of a film.

[0077] Before laminating the film to the glass plate, the release layer on the film used to protect the film from being dirty and sticky needs to be removed. Usually, the release layer is removed manually, and special personnel are required to perform the operation of removing the release layer. In order to improve the automation of the equipment, reduce the dependence on human resources, reduce costs and improve efficiency, the glass laminating equipment proposed by the present invention also includes a release layer peeling mechanism 500.

[0078] like Figures 13 to 16 The release layer peeling mechanism 500 includes a clamping mechanism 510 and a pulling mechanism 520, and the clamping mechanism 510 is fixed to the pulling mechanism 520; the clamping mechanism 510 includes a clamping cylinder 511, a rear clamping jaw 513 and a front clamping jaw 512, and a stripping knife 514 is provided at the lower end of the rear clamping jaw 513, and the stripping knife 514 has a knife head protruding forward, and the lower end of the front clamping jaw 512 has a clamping portion 5120, and the clamping portion 5120 is used to cooperate with the stripping knife 514 to clamp the pulling portion 530 of the release layer; the clamping portion 5120 has a hole or a slot for the pulling portion 530 to pass through.

[0079] The front clamping jaw 512 is connected to the clamping cylinder 511, and the clamping cylinder 511 is used to drive the front clamping jaw 512 to move backward and upward relative to the rear clamping jaw 513 to fold and clamp the pulling portion 530 of the release layer; the pulling mechanism 520 is connected to a movable module 540, and the pulling mechanism 520 is used to pull the pulling portion 530 of the release layer to move after the clamping mechanism 510 clamps the pulling portion 530 of the release layer to peel off the release layer.

[0080] The release layer peeling mechanism 500 further includes an upper and lower cylinder, which is used to drive the rear clamping jaw 513 to move up and down, so as to drive the rear clamping jaw 513 downward before peeling the release layer, so that the stripping knife 514 is attached to the film. The position where the stripping knife 514 contacts the film is a corner of the film, which is also the corner where the pulling part 530 is set on the film. When the release layer peeling mechanism 500 performs the release layer peeling operation, the rear clamping jaw 513 moves downward, the stripping knife 514 presses the film to isolate the pulling portion 530 of the film, and the clamping cylinder 511 drives the front clamping jaw 512 to move backward and upward, and the pulling portion 530 of the film extends into the clamping portion 5120 of the front clamping jaw 512. The clamping portion 5120 continues to move backward and upward under the drive of the clamping cylinder 511, and fits with the rear clamping jaw 513, folding the pulling portion 530 of the film and clamping the pulling portion 530 of the film under the joint action of the stripping knife 514, the front clamping jaw 512 and the rear clamping jaw 513, and under the pulling action of the pulling mechanism 520, the release layer is peeled off.

[0081] In order to prevent the release layer peeling mechanism 500 from damaging the film when peeling the release layer, the present invention is provided with a rear clamping jaw mounting plate 516 and a front clamping jaw mounting plate 515. The front clamping jaw mounting plate 515 drives the front clamping jaw 512 to move under the action of the clamping cylinder 511. The rear clamping jaw mounting plate 516 moves in the same direction as the front clamping jaw mounting plate 515, and the rear clamping jaw mounting plate 516 is also connected to an elastic reset mechanism; the front clamping jaw 512 moves and moves with the front clamping jaw 512. When the rear clamping jaw 513 and the stripping knife 514 clamp the pulling portion 530 of the release layer, after clamping the pulling portion 530 of the release layer, the rear clamping jaw 513 and the stripping knife 514 will be driven to continue to move backward and upward for a short distance; at this time, the rebound force of the elastic reset mechanism ensures the clamping force on the pulling portion 530 of the release layer, and the release layer can be peeled off to form an opening and the bottom of the stripping knife 514 can be separated from the film, avoiding damage to the film when pulling backward.

[0082] In order to be suitable for filming curved glass, especially concave glass, the glass filming device proposed by the present invention also includes a film forming mechanism 600. Figures 17 to 19 As shown, the film forming mechanism 600 includes a curved punch 610, a screen assembly 620 and a third driving mechanism 630; the screen assembly 620 includes a frame plate 621 and a screen 622; the curved punch 610 is located on one side of the screen 622, and the other side of the screen 622 is provided with a sticky material to adhere the film; the third driving mechanism 630 drives the curved punch 610 and the screen assembly 620 to move relative to each other, so that the film adhered to the screen 622 is formed.

[0083] Specifically, after the film positioning mechanism accurately positions the film and the release layer is removed by the release layer peeling mechanism 500, the film is transported to the film forming mechanism 600. At present, the transport mechanism can accurately transport the object to be transported to the target area, and the position accuracy can reach the micron level. How to transport is a prior art and does not belong to the content of the present invention, and will not be repeated here. The diaphragm with the release layer removed is transported to the upper side of the wire mesh 622 and adhered to the wire mesh 622. The curved punch 610 is located on the lower side of the wire mesh 622. Driven by the third driving mechanism 630, the curved punch 610 moves upward relative to the wire mesh 622 and lifts up the wire mesh 622, so that the wire mesh 622 fits the convex surface of the curved punch 610; the diaphragm is adhered to the wire mesh 622 and is positioned opposite to the curved punch 610. When the wire mesh 622 fits the convex surface of the curved punch 610, the diaphragm also fits the convex surface of the curved punch 610, thereby completing the molding of the diaphragm.

[0084] In order to make the screen 622 fit the curved convex mold 610 better, the screen assembly 620 further includes a pressing block 623, which is arranged at the edge of the screen 622 to press and fix the screen 622; the frame plate 621 is arranged inside the pressing block 623 and is located on the side of the screen 622 close to the curved convex mold 610, so as to cooperate with the pressing block 623 to tension the screen 622. In other embodiments, in order to simplify the structure of the screen assembly 620, the screen assembly 620 can be composed of the frame plate 621 and the screen 622, and the screen 622 is tensioned and fixed to the frame plate 621.

[0085] In order to accurately control the height of the curved surface punch 610, the third driving mechanism 630 uses a lifting screw motor 631 to drive the curved surface punch 610 to realize the forming of the diaphragm. Specifically, the third driving mechanism 630 includes a lifting screw motor 631, a screw sleeve 633 and a lifting seat 634; the screw sleeve 633 is sleeved on the screw of the screw motor and fixedly connected to the lifting seat 634; the lifting seat 634 is connected with upper and lower slide rails 635, and the curved surface punch 610 is fixed to the lifting seat 634 to move up and down under the drive of the screw motor.

[0086] The edges of the formed membrane are bent downward, forming an upwardly convex arc surface as a whole. When it is bonded to the glass plate, the middle part is bonded together first, and the bonding part gradually extends to the surrounding areas until the membrane is completely bonded to the glass plate, which can effectively avoid residual bubbles between the membrane and the glass plate.

[0087] The present invention includes two diaphragm forming mechanisms, one of which is located below the glass positioning mechanism 100 when the rotating arm 210 of the flipping and bonding mechanism 200 is at 0 degrees, and is enclosed with the first cavity 210a to form a sealed cavity; the other is located below the glass positioning mechanism 100 when the rotating arm 210 of the flipping and bonding mechanism 200 is at 180 degrees, and is enclosed with the second cavity 210b to form a sealed cavity; the process of bonding the diaphragm and the glass is completed in the sealed cavity.

[0088] In order to further reduce the possibility of bubbles between the film and the glass plate during the bonding process and reduce the image when bubbles exist, the present invention evacuates the cavity where the film and the glass plate are bonded to make the film and the glass plate in a low-pressure environment when they are bonded.

[0089] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
