Description

Technical Field

[0001] This utility model relates to the field of touch screen bonding technology, and in particular to a touch screen panel bonding machine. Background Technology

[0002] A touchscreen is a sensor-based display device that receives input signals from touch. When a graphical button on the screen is touched, the haptic feedback system drives various connected devices according to a pre-programmed program. It can replace mechanical button panels. Computer monitors, mobile phone displays, smart home control screens, and other display terminals are often equipped with touchscreen panels. To prevent personal injury from glass shards flying when the touchscreen panel breaks, a layer of explosion-proof film with tensile and tensile strength is usually applied to the front of the touchscreen panel. This explosion-proof film is generally produced using a laser engraving machine or by die-cutting. The board has several mounting holes for fixing the touch screen panel. These holes are spaced apart along the circumference of the touch screen panel. An explosion-proof film is attached to the touch screen panel surface at the positions between these mounting holes. Traditionally, the explosion-proof film is installed manually by aligning it with the touch screen panel and sliding and pressing it to ensure correct placement. However, this method cannot guarantee the bonding strength, resulting in low bonding quality between the explosion-proof film and the touch screen panel. Therefore, an automatic bonding machine has been developed to replace manual bonding, such as application number 2. A reliable film-pressing laminating machine (016107373350) includes a dual-mold fixture mechanism, a film transfer mechanism, and a film pressing mechanism. The dual-mold fixture mechanism includes a film pressing fixture and a positioning fixture. The positioning fixture is used to position the film, and the film pressing fixture is used to position the glass sheet and the film during pressing. There are at least four dual-mold fixture mechanisms, each corresponding to station one, station two, station three, and station four. The film transfer mechanism is located at station two. The film pressing mechanism is located at station four. The film pressing mechanism includes a pressing mold, which includes a pressing top plate and a pressing bottom plate. A membrane top plate is installed on top of the membrane pressing base plate; the membrane pressing base plate is provided with a membrane pressing groove, and the edge of the membrane pressing groove is provided with a curved groove; the bottom of the membrane pressing base plate is provided with a vacuum adsorption gas path structure, which includes crisscrossing adsorption gas path grooves; the first station is used to feed the membrane sheet to the positioning fixture and to unload the glass sheet with the membrane sheet attached from the membrane pressing fixture; the second station is used to move the membrane sheet from the positioning fixture to the membrane pressing fixture; the third station is used to remove the protective film of the membrane sheet and to feed the glass sheet; the fourth station is used to pick up the glass sheet and then press it onto the membrane sheet located in the membrane pressing fixture. In application, station one is used to feed the diaphragm to the positioning fixture and to unload the glass sheet with the diaphragm attached from the pressing fixture; station two is used to move the diaphragm from the positioning fixture to the pressing fixture; station three is used to remove the protective film from the diaphragm and to feed the glass sheet; station four is used to pick up the glass sheet and then press it onto the diaphragm located in the pressing fixture.In application, a worker needs to place the film to be processed onto the positioning fixture at station one. At station two, the film transfer device moves the film to the pressing fixture. At station three, a worker places the glass sheet onto the glass sheet positioning block and removes the protective film from the film. At station four, the pressing mechanism picks up the glass sheet and then presses it onto the film located in the pressing fixture. Finally, the positioning fixture and the pressing fixture return to station one, and a worker unloads the glass sheet with the film attached from the pressing fixture and loads it onto the positioning fixture.

[0003] The aforementioned laminating machine requires manual feeding of the film at station one, but manual film feeding results in low production efficiency. Furthermore, since station one and station three are located at opposite ends of the turntable, another operator is also required at station three to feed the glass sheet. This necessitates the simultaneous operation of two workers, leading to higher production costs.

[0004] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a touch screen panel laminating machine to solve the problems of low production efficiency and high production cost of existing laminating machines.

[0006] To achieve its purpose, this utility model adopts the following technical solution:

[0007] A touch screen panel laminating machine includes a frame, a turntable, a positioning fixture, and a film feeding device. The turntable is rotatably mounted on the frame, the positioning fixture is mounted on the turntable, and the film feeding device has a film placement device and a film transfer device. The film transfer device is located outside the turntable and is mounted on the frame. The positioning fixture has a lower template and an upper template that covers the lower template. The lower template is fixedly mounted on the turntable, and the top surface of the lower template has a placement platform for placing an explosion-proof film. The upper template is hinged to the lower template in a manner that allows it to be flipped upwards and laid flat, with its first end flipped out of the turntable. The bottom surface of the upper template is provided with a positioning structure for positioning the touch screen panel. A positioning mechanism located outside the turntable and capable of positioning the first end of the upper template is mounted on the frame. An ionizer capable of lateral translation between the positioning mechanism and the positioning fixture and suspended above the turntable is mounted on the frame to roughen the surface of the panel.

[0008] The film-laying device has a placement seat on which several explosion-proof films are stacked. The placement seat is provided with several circumferentially arranged positioning members. Each positioning member forms a receiving space for the explosion-proof films to be received. The positioning members are installed on the placement seat in a manner that moves horizontally toward the center of the receiving space. The placement seat is located outside the upper part of the receiving space and is provided with a separation device that can separate the films on the film-laying device. The film-laying device is installed on the frame in a manner that can move up and down and move horizontally along the receiving space to the upper template.

[0009] With the membrane transfer device and ionizer moving laterally in the left-right direction, the placement seat is located on the top left end of the frame, and the turntable is located on the top right end of the frame. The frame has a mounting frame extending in the left-right direction on the rear side of the placement seat. The membrane transfer device has a membrane transfer head, which is mounted on the front left end of the mounting frame in a manner that allows it to move left and right, up and down, forward and backward, and rotate circumferentially. The ionizer is mounted on the front right end of the mounting frame in a manner that allows it to move left and right along the mounting frame. The positioning mechanism is located on the right side outside the turntable and is set opposite to the upper template.

[0010] The lower template is locked on the top surface of the turntable. The platform is a locking plate that is locked on the top surface of the lower template. A through hole is provided in the middle of the locking plate. A soft adsorption block is provided in the through hole to protect the explosion-proof diaphragm when the upper and lower templates are facing each other. The upper template extends in the left and right direction. One end of the upper template is hinged to one end of the lower template.

[0011] On the top surface of the frame, on the right side of the turntable, there is a stacking block that allows the right end of the upper template to be horizontally stacked on top when the upper template is horizontally flipped out of the turntable. The right side of the stacking block and one side of the upper template are both recessed with positioning grooves that run vertically through each other and are positioned opposite each other when the upper template is horizontally flipped out of the turntable. The positioning mechanism has a positioning cylinder on the right side of the stacking block, which faces left. The output end of the positioning cylinder is connected to a top pressing block that can extend into the positioning groove. Several positioning rods that can extend into the mounting holes of the touch screen panel are protruding from the middle of the bottom surface of the upper template. The positioning rods form a fitting space for the explosion-proof film to be attached. The top surface of the placement platform is recessed with positioning grooves corresponding to the positions of the positioning rods, allowing each positioning rod to extend into them. The positioning rods constitute the above-mentioned positioning structure.

[0012] The ion generator has a nozzle capable of ejecting plasma gas flow. The nozzle is vertically suspended above the bonding space of the upper template. The nozzle is mounted on the right side of the front side of the mounting frame in a manner that allows it to move left and right along the front side of the mounting frame to the point directly above the bonding space of the upper template. A blower is provided on the frame, with the output end of the blower facing the bonding space.

[0013] The placement base has a lower mounting plate and an upper placement plate. The lower mounting plate is locked to the left end of the top surface of the frame and is located outside the front side of the mounting frame. The upper placement plate is located above the lower mounting plate. The positioning member has a plurality of positioning blocks arranged at intervals around the upper placement plate in the circumferential direction. The top surface of the upper placement plate and each positioning block form the aforementioned accommodating space with the top surface open, in which a plurality of explosion-proof diaphragms are stacked in sequence. Each positioning block is mounted on the lower mounting plate in a manner that allows it to move toward the center of the accommodating space. One of the positioning blocks has the aforementioned separation device that can separate the uppermost explosion-proof diaphragm in the accommodating space from the other explosion-proof diaphragms.

[0014] The positioning blocks are provided in four parts. The four positioning blocks include a left limiting block on the left side of the upper placement plate, a front limiting block on the front side of the upper placement plate, a right limiting rod on the right side of the upper placement plate, and a rear limiting plate on the rear side of the upper placement plate. The upper placement plate is mounted on the lower mounting plate in a way that allows it to move up and down. The left limiting block and the front limiting block are both vertically set blocks. The side of the vertical block facing away from the upper placement plate is provided with a mounting post that is vertically set on the lower mounting plate. The vertical block is mounted on the mounting post in a way that allows it to move towards or away from the upper placement plate. The right limiting rod is vertically set and is vertically mounted on the lower mounting plate in a way that allows it to move left and right towards the upper placement plate. The top surface of the rear limiting plate is provided with a brush, one end of which is locked together with the rear limiting plate and the other end of which faces the accommodating space and extends in the left and right direction. The brush is the aforementioned partition structure.

[0015] The top surface of the frame has a detection window on the right side of the placement seat. The detection window is located between the turntable and the placement seat and below the film transfer head. A transparent sealing cover is installed on the detection window. Inside the frame, below the detection window, there is a visual inspection device that can detect whether the explosion-proof film on the film transfer head that has moved to the top of the detection port is aligned. The lower template is located outside the right side of the detection window.

[0016] The mounting bracket has a rear movable plate that can move up and down on the front left side, a front movable plate that can move left and right along the rear movable plate on the front side, and a lower movable plate that extends out from under the rear movable plate and can move back and forth along the bottom of the front movable plate on the bottom surface of the front movable plate. The film transfer head is mounted on the bottom surface of the lower movable plate in a manner that allows it to rotate circumferentially.

[0017] The film transfer head is a transparent block, and the bottom surface of the film transfer head has several vacuum nozzles that are evenly spaced along the circumferential direction of the film transfer head. The top surface of the film transfer head is provided with a light source that is connected to the lower moving plate and can transmit light downward from the film transfer head.

[0018] This novel touchscreen panel laminating machine, in application, involves stacking several explosion-proof films within a receiving space. The positioning components move relative to the center of the receiving space to clamp the explosion-proof films within the space. A film transfer device is activated, moving to the top surface of each explosion-proof film and lifting it upwards. A separation device prevents the film transfer device from simultaneously lifting multiple explosion-proof films. The film transfer device then moves towards the lower template, completing the removal of the explosion-proof films. Simultaneously, the turntable rotates, the positioning fixture extends laterally and aligns with the placement seat, and the upper template is flipped upwards until it is horizontally positioned. The film transfer device moves above the placement table, then moves downwards, placing the explosion-proof films on the placement table. The film transfer device then resets. Simultaneously, a positioning mechanism holds the upper template horizontally, fixing it in place. The touchscreen panel is positioned on the upper template using the positioning structure. The protective film on the touchscreen panel surface is then removed, and an ionizer cleans the touchscreen panel surface. The surface undergoes plasma treatment, and the upper template is flipped upwards again. The upper template rotates to a horizontal position directly above the lower template, completing the placement of the touchscreen panel. Finally, the positioning fixture moves to the underside of the lamination mechanism, and the lamination mechanism performs vacuum lamination on the positioning fixture, achieving a tight fit between the explosion-proof film and the touchscreen panel. After vacuum lamination, the positioning fixture is reset, and the upper template is manually flipped to a horizontal position. Due to the positioning structure, the finished product with the explosion-proof film and touchscreen panel tightly bonded is placed on the upper template. During the manual loading and unloading of finished products and touchscreen panels on the upper template, the lower template can be automatically loaded simultaneously, resulting in higher production efficiency. Compared with existing technologies, using a film transfer device to automatically load the explosion-proof film onto the lower template results in more precise loading and higher production efficiency. Moreover, during the loading of the explosion-proof film, unloading and placement of the touchscreen panel can be performed simultaneously, requiring only one worker for either loading the touchscreen panel or unloading the finished product, thus reducing production costs.

[0021] Figure 3 This is a schematic diagram of the present invention with the placement base omitted. Detailed Implementation

[0022] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0023] A touch screen panel laminating machine, such as Figures 1-3As shown, the device includes a frame 1, a turntable 2, a positioning fixture 3, and a film feeding device. The turntable 2 is rotatably mounted on the frame 1, and the positioning fixture 3 is mounted on the turntable 2. The film feeding device has a film placement device and a film transfer device. The film transfer device is located outside the turntable 2 and is mounted on the frame 1. Specifically, the turntable 2 is located on the right end of the top surface of the frame 1. The frame 1 has a mounting frame 4 extending in the left-right direction on the rear side of the placement seat 5. The mounting frame 4 has a horizontal beam 41 and a vertical beam 42. There are two vertical beams 42, which are spaced apart on the left and right. The horizontal beam 41 extends in the left-right direction above the two vertical beams 42. The turntable 2 is rotatably located on the right end below the horizontal beam 41. A pressing mechanism is located above the rear end of the turntable 2, and the pressing mechanism is located outside the rear side of the horizontal beam 41. The rotational mounting method of the turntable 2, the specific structure of the pressing mechanism, and the method by which the pressing mechanism tightly adheres the explosion-proof film and the touch screen panel are known technologies and will not be elaborated here.

[0024] The positioning fixture 3 has a lower template 31 and an upper template 32 covering the lower template 31. The lower template 31 is fixedly installed on the turntable 2. The top surface of the lower template 31 has a placement platform 311 for placing the explosion-proof film. The upper template 32 is hinged to the lower template 31 in a manner that allows it to be flipped upwards and laid flat, with its first end flipped out of the turntable 2. Specifically, the turntable 2 is provided with several positioning fixtures that are spaced around the circumference of the turntable 2 and that allow the upper template 32 and the lower template 31 to be laid horizontally on the same straight line as the film-laying device. Taking two relatively parallel positioning fixtures on the turntable as an example, the lower template 31 is locked to the top surface of the turntable 2. That is, the top surface of the lower template 31 has several vertically penetrating upper screw holes. The top surface of the turntable is recessed with a lower screw groove corresponding to the position of the upper screw holes. The lower template 31 is locked to the turntable by bolts passing through the upper screw holes and into the lower screw groove. The placement platform 311 is locked to the lower template. The locking plate on the top surface of template 31 has a through hole in the middle. A soft adsorption block 3111, which protects the explosion-proof diaphragm when the upper template 32 and lower template 31 are facing each other, is installed inside the through hole. When the upper template 32 and lower template 31 are horizontally unfolded, the upper template extends horizontally and is positioned on the right side of the lower template 31. The left end of the upper template 32 is hinged to the right end of the lower template 31. Extending out of the turntable 2, the upper template 31 has a fixing block 312 protruding upward from the right end of its top surface, located outside the right side of the placement platform 311 and extending in the front-back direction. The top surface of the fixing block 312 has two first hinge blocks protruding upward and spaced apart in the front-back direction. The left side of the upper template 32 has a second hinge block protruding and extending between the two first hinge blocks. The left end of the upper template 32 is hinged to the right end of the lower template 31 via a hinge shaft that passes through both the first and second hinge blocks. In application, the upper template 32 is flipped upward, and its left end rotates upward around the hinge shaft until it is placed horizontally.

[0025] The bottom surface of the upper template 32 is provided with a positioning structure for positioning the touch screen panel. Specifically, a number of positioning rods 322 protrude from the middle of the bottom surface of the upper template 32 and can extend into the mounting holes of the touch screen panel. The positioning rods 322 form a fitting space for the explosion-proof film to be attached. The top surface of the placement platform 311 is recessed at the position corresponding to the positioning rods 322, and positioning grooves are provided for the positioning rods 322 to extend into. The outer diameter of each positioning rod matches the inner diameter of the touch screen panel. The positioning rods 322 constitute the above-mentioned positioning structure. In application, the upper template 32 is flipped upwards to a horizontal position, and the explosion-proof film is placed on the placement platform. The soft adsorption block 3111 can adsorb the explosion-proof film onto the soft adsorption block 3111. Then, the mounting holes of the touch screen panel are aligned with the positioning rods, and each positioning rod extends into its respective mounting hole, so that the touch screen panel is limited on the upper template 32. Then, the upper template 32 is flipped upwards, so that the upper template 32 moves below the lower template 31. At this time, the soft adsorption block falls into the fitting space, and the upper template 32 and the lower template 31 are set parallel to each other vertically. Moreover, the soft adsorption block 3111 can not only adsorb the explosion-proof film onto it, but also play a buffering role when the explosion-proof film and the touch screen panel are relatively attached, and also facilitate the detachment of the explosion-proof film from the soft adsorption block 3111.

[0026] A positioning mechanism is installed on the frame 1, located outside the turntable 2, to position the first end of the upper template 32. The positioning mechanism is positioned on the right side of the turntable 2 and opposite to the upper template 32. Specifically, a stacking block 11 is provided on the top surface of the frame 1, outside the right side of the turntable 2, so that the right end of the upper template 32 is horizontally stacked on top when it is horizontally flipped out of the turntable 2. The right side of the stacking block 11 and one side of the upper template 32 are both recessed with vertically penetrating positioning grooves. When the upper template 32 is horizontally flipped out of the turntable 2 and placed horizontally, the positioning groove is located on the right end of the upper template 32. The two positioning slots are arranged vertically opposite each other. The positioning mechanism has a positioning cylinder 12 on the right side of the stacking block 11. The positioning cylinder 12 is arranged to the left, and the output end of the positioning cylinder 12 is connected to a top pressing block 121 that can extend into the two positioning slots. When in use, when the upper template 32 is flipped upward to be placed horizontally, the right end of the upper template 32 extends out of the turntable 2 and is horizontally stacked on the top surface of the stacking block 11. Then, the positioning cylinder 12 is driven, and the top pressing block 121 moves to the left until it presses against the bottom of the two positioning slots. The upper template 32 is horizontally fixed and cannot move. Then, the touch screen panel is positioned and placed by each positioning rod.

[0027] An ionizer for roughening the panel surface is installed on the frame 1, capable of lateral translation between the positioning mechanism and the positioning fixture 3 and suspended above the turntable 2. Specifically, the ionizer is installed on the front right end of the crossbeam 41 in a manner that allows it to translate laterally along the crossbeam 41. That is, the ionizer has a nozzle 13 capable of ejecting plasma gas flow. The nozzle 13 is vertically suspended above the fitting space of the upper template 32. The outer diameter of the nozzle 13 is less than or equal to the inner diameter of the fitting space. The nozzle 13 is installed on the front right end of the crossbeam 41 in a manner that allows it to move laterally along the front side of the crossbeam 41. That is, a sliding rod 411 extending in the left-right direction is provided on the front right end of the crossbeam 41, and a sliding block 131 slidingly fitted on the sliding rod 411 is provided on the upper outer wall of the nozzle 13. A driving cylinder (not shown in the figure) for driving the sliding block 131 to move left and right is provided on the front right end of the beam 41. The nozzle 13 is connected to the plasma machine. A blower is provided on the frame 1. The output end of the blower faces the fitting space. The blower has a blowing head 14, which is installed on the bottom right end of the crossbeam. The output end of the blowing head 14 is forward-facing and located on the rear side of the stacking block 11. The output end of the blowing head 14 is a strip structure extending in the left and right direction. The way the nozzle 13 processes the surface of the touch screen panel through the plasma machine is a known technology, such as the plasma spray gun with application number 201520626020X. The working principle of the spray gun is similar to that of the nozzle in this invention. The way the blowing head blows air is a known technology to those skilled in the art, and will not be described in detail here. During application, after placing the touch screen panel, peel off the protective film on the surface of the touch screen panel, start the drive cylinder, move the nozzle to directly above the touch screen panel, start the plasma machine, and the nozzle treats the surface of the touch screen panel to increase the adhesion of the touch screen panel, which is conducive to the bonding of the explosion-proof film to the touch screen panel. Then start the blower to blow the debris generated by the ion treatment on the surface of the touch screen panel out of the bonding space.

[0028] The film-laying device has a placement seat 5 for stacking several explosion-proof films. The placement seat 5 is provided with several circumferentially arranged positioning members 6, each positioning member 6 forming a receiving space for each explosion-proof film. The positioning members 6 are installed on the placement seat 5 in a manner that allows them to translate towards the center of the receiving space. The placement seat 5 is located at the upper part of the receiving space and is equipped with a separation device for separating the explosion-proof films on the film-laying device. Specifically, the placement seat 5 is located on the top left end of the frame 1. The placement seat 5 has a lower mounting plate 51 and an upper placement plate 52. The lower mounting plate 51 is locked to the top left end of the frame 1. The locking method of the lower mounting plate 51 is similar to that of the lower template. Located below the front side of the crossbeam 41, the upper placement plate 52 is positioned above the lower mounting plate 51. The positioning member 6 has several positioning blocks spaced around the upper placement plate 52 in the circumferential direction. The top surface of the upper placement plate 52 and each positioning block form the aforementioned accommodating space, which is open at the top and allows several explosion-proof diaphragms to be stacked sequentially. Each positioning block is mounted on the lower mounting plate 51 in a manner that allows it to move toward the center of the accommodating space. One of the positioning blocks has a separation device that can separate the uppermost explosion-proof diaphragm in the accommodating space from the other explosion-proof diaphragms. There are four positioning blocks. The four positioning blocks have a left limiting block 61 on the left side of the upper placement plate 52 and a left limiting block 61 on the front side of the upper placement plate 52. The upper mounting plate 52 has a front limiting block 62, a right limiting rod 63 on the right side of the upper mounting plate 52, and a rear limiting plate 64 on the rear side of the upper mounting plate 52. The upper mounting plate 52 is mounted on the lower mounting plate 51 in a way that allows it to move up and down, i.e., the upper mounting plate 52 is suspended above the lower mounting plate 51. The frame 1 is equipped with a moving cylinder (not shown in the figure). The output end of the moving cylinder extends upward beyond the lower mounting plate 51, and the end of the output end of the moving cylinder is connected to the upper mounting plate. The left side of the upper mounting plate 52 is recessed with a left extension groove that extends vertically and allows the left limiting block to extend into it. The left limiting block 61 and the front limiting block 62 are both vertically set blocks. On the side of the vertical block facing away from the upper mounting plate 52, there is a vertically set lower mounting plate 51. The mounting post 521 on the mounting plate 51 has a vertical block that can move towards or away from the mounting plate 52. The mounting post 521 has vertical blocks and horizontal blocks that are perpendicular to each other. The vertical blocks are vertically positioned outside the side of the vertical block facing away from the mounting plate 52. The vertical block of the left limiting block 61 is in the left extension groove, and the horizontal block is at the lower end of the side of the vertical block facing away from the vertical block. The vertical block is locked on the lower mounting plate 51. The vertical block is provided with several adjusting rods 5211, one end of which is connected to the vertical block and the other end of which protrudes out of the vertical block. Each adjusting rod 5211 is spaced apart in the vertical direction, and the outer wall of the adjusting rod 5211 is provided with external threads. A screw block is screwed on the end of the adjusting rod 5211 facing away from the vertical block.The right limiting rod 63 is vertically installed on the lower mounting plate 51 so as to be able to move left and right toward the upper placement plate 52. That is, the right limiting rod 63 has a stop rod and a fixing rod arranged perpendicularly to each other. The right side of the upper placement plate 52 is recessed with a right extension groove that extends vertically. The stop rod is vertically installed in the right extension groove. The lower end of the stop rod is connected to the fixing rod. The fixing rod extends left and right on the lower mounting plate 51 and has a strip-shaped through hole that extends left and right and extends vertically. The lower mounting plate 51 is recessed with a locking groove within the range of the strip-shaped through hole. The fixing rod is locked to the lower mounting plate 51 by passing through the strip-shaped through hole with a locking bolt. The right limiting rod 63 can be adjusted left and right by the strip-shaped through hole and the locking bolt. One end of the right limiting rod is fixed to the rear limiting plate 64 on the top surface. The brush 641 extends from one end toward the accommodating space and in the left-right direction, with the front end of the brush extending into the accommodating space. The brush 641 is the aforementioned partition structure. The rear limiting plate 64 moves toward the accommodating space in a similar manner to the front limiting block 62. In practical applications, one of the positioning blocks can be fixed on the lower mounting plate 51, while the other three positioning blocks can move relative to the accommodating space. This also serves to position the explosion-proof diaphragm and to allow the application of explosion-proof diaphragms of different sizes. In application, adjust the positioning blocks toward the accommodating space until each positioning block clamps the explosion-proof diaphragm, i.e., stack several explosion-proof diaphragms in the accommodating space. Adjust the front limiting block 62, the left limiting block 61, and the rear limiting plate 64 to the required positions. Screw the screw block onto the adjusting rod, adjust the right limiting rod 63 to the required position, and then tighten the locking bolt to achieve the adjustment of the accommodating space. Each positioning block can move relative to the accommodating space, thus adjusting the inner diameter of the accommodating space to facilitate the placement of explosion-proof diaphragms of different sizes. Furthermore, when removing the top explosion-proof diaphragm, the brush can separate the top diaphragm from the others, making it easy to remove a single diaphragm.

[0029] The film transfer device is mounted on the frame 1 in a manner that allows it to move up and down and to translate laterally between the accommodating space and the upper template 32. Specifically, the film transfer device has a film transfer head 7, which is mounted on the front left end of the mounting frame 4 in a manner that allows it to move left and right, up and down, forward and backward, and rotate circumferentially. That is, the front left end of the mounting frame 4 is provided with a rear moving plate 81 that can move in the vertical direction, and the front side of the rear moving plate 81 is provided with a front moving plate 82 that can move left and right along the rear moving plate 81. The bottom surface of the front moving plate 82 has a protrusion extending from the rear moving plate 81. A lower moving plate 83 is provided, which can move back and forth along the bottom surface of the front moving plate 82. The film transfer head 7 is mounted on the bottom surface of the lower moving plate 83 in a circumferentially rotatable manner. That is, a first slide rail 411 extending in the vertical direction is provided on the front side of the crossbeam 41 corresponding to the position of the rear moving plate 81. A first slider (not shown in the figure) is provided on the rear side of the rear moving plate 81 and slides with the first slide rail 411. A first cylinder (not shown in the figure) driving the first slider to move up and down is provided on the front side of the crossbeam 41 above the first slide rail 411. The output end of the first cylinder is connected to the first slide rail 411. A slider is connected to the front of the rear moving plate 81, which has a second slide rail 811 extending in the left-right direction. A second slider that slides with the second slide rail 811 is located on the rear of the front moving plate 82. A second cylinder that drives the second slider to move left and right is located on the left side of the second slide rail 811 on the crossbeam 41. The output end of the second cylinder is connected to the second slider. A third slide rail is located on the top surface of the lower moving plate 83, and a third slider that slides with the third slide rail is located on the bottom surface of the front moving plate 82. A drive mechanism is located on the top surface of the lower moving plate 83 behind the third slide rail. The third cylinder moves the third slider back and forth. The output end of the third cylinder is connected to the third slider. The top surface of the lower moving plate 83 is provided with a vertically mounted rotary motor 831. The output end of the rotary motor 831 extends downward beyond the lower moving plate 83 and is connected to the film transfer head 7. The bottom surface of the film transfer head 7 has several vacuum nozzles evenly spaced along the circumferential direction of the film transfer head 7. The method by which the film transfer head 7 picks up the explosion-proof film through the vacuum nozzles and the method by which the film transfer head 7 moves are well known to those skilled in the art and will not be described in detail here.In application, starting the first cylinder moves the film transfer head 7 up and down, starting the second cylinder moves the film transfer head left and right, starting the third cylinder moves the film transfer head 7 back and forth, and starting the rotary motor rotates the film transfer head 7 circumferentially. Driving the film transfer head 7 to directly above the receiving space, the first cylinder is activated, causing the film transfer head 7 to move downwards and be lifted by the vacuum nozzle. Driving the first cylinder again moves the film transfer head upwards. During the lifting process from the receiving space, the brush ensures that the vacuum nozzle can lift a single explosion-proof film sheet each time. The second cylinder is activated, moving the film transfer head 7 to the right above the soft adsorption block on the lower film plate 31. If the lifted explosion-proof film sheet is not in the correct position, the rotary motor, the first cylinder, the second cylinder, and the third cylinder automatically adjust the position of the film transfer head to correct the position of the explosion-proof film sheet. Activating the first cylinder again moves the film transfer head 7 downwards, placing the explosion-proof film sheet on the soft adsorption block.

[0030] This novel touchscreen panel laminating machine, in application, stacks several explosion-proof films in a receiving space. The positioning components are controlled to move relative to the center of the receiving space until they clamp the explosion-proof films within the space. The film transfer device is activated, and the film transfer head 7 moves to the top of the receiving space. The film transfer head 7 then moves down to the top surface of each explosion-proof film and lifts it upwards through a vacuum nozzle. The film transfer head 7 moves to the right, thus completing the removal of the explosion-proof film. Simultaneously, the turntable 2 rotates, and one of its positioning fixtures extends horizontally and is aligned with the placement seat 5 on the same straight line, flipping upwards. Template 32 is horizontally stacked on the stacking block 11 at its right end. The film transfer head 7 moves to the right above the soft adsorption block of the lower template 31. The film transfer head 7 moves down, and the explosion-proof film is adsorbed onto the soft adsorption block. The film transfer head 7 then resets. Simultaneously, the positioning cylinder 12 is activated, and the top pressing block 121 presses against the upper template 32, fixing the upper template 32 horizontally. The touch screen panel is positioned on the upper template 32 by the positioning rod. The protective film on the surface of the touch screen panel is removed. The ion machine performs plasma treatment on the surface of the touch screen panel. The blowing head 14 blows the debris generated during the ion treatment of the touch screen panel surface out of the upper template. Outside of step 32, the upper template 32 is flipped upwards again, rotating until it is horizontal and directly above the lower template 31, completing the placement of the touch screen panel. Turntable 2 rotates again, and the positioning fixture with the explosion-proof film and touch screen panel installed moves to the underside of the laminating mechanism for vacuum lamination, achieving a tight fit between the explosion-proof film and the touch screen panel. Meanwhile, the other positioning fixture, which is not yet loaded, rotates to the front of the frame. During the vacuum lamination process, the other positioning fixture can be loaded simultaneously, increasing production efficiency. After vacuum lamination, the completed positioning fixture is reset, and the upper template is manually flipped to a horizontal position. Thanks to the positioning rod, the finished product, with the explosion-proof film and touch screen panel tightly bonded together, is placed on the upper template. During the manual unloading of finished products and the loading of touch screen panels, the lower template can be automatically loaded simultaneously, resulting in higher production efficiency. Compared with existing technologies, the use of a film transfer device to automatically load the explosion-proof film onto the lower template 31 results in more precise loading and higher production efficiency. Moreover, during the loading of the explosion-proof film, the unloading of finished products and the placement of touch screen panels can be carried out simultaneously, and only one worker is needed at the front of the turntable to load the touch screen panels or unload the finished products, resulting in lower production costs.

[0031] In this invention, the preferred feature is that the film transfer head 7 is a transparent block. The top surface of the film transfer head 7 is provided with a light source that is connected to the lower moving plate 83 and allows light to pass through from the film transfer head 7. The light emission method of the light source is a known technology and will not be described in detail here. The top surface of the frame 1 is provided with a detection window on the right side of the placement seat 5. The detection window is located between the turntable 2 and the placement seat 5 and below the film transfer head 7. A transparent sealing cover 15 is sealed on the detection window. A visual inspection device is provided inside the frame 1 below the detection window to detect whether the explosion-proof film on the detection window is aligned. The lower template 31 is located outside the right side of the detection window. The visual inspection device is electrically connected to the first cylinder, the second cylinder, the third cylinder and the rotating motor. The method by which the visual inspection device detects whether the explosion-proof film on the film transfer head 7 is aligned is a technology known to those skilled in the art. In application, the setting of the light source can make the explosion-proof film on the film transfer head more clearly visible. The film transfer head takes out a single explosion-proof film from the accommodating space, passes through the detection window, and is detected by the visual inspection device. After the detection is completed, if the explosion-proof film has a deviation, the first cylinder, the second cylinder, the third cylinder or the rotating motor is started to adjust the position of the film transfer head 7 so that the explosion-proof film can be aligned and placed into the lower template 31.

[0032] In this invention, the lower template 31 has a limiting block 312 protruding upwards at a position outside the placement platform 311 on its top surface. The limiting block 312 has a limiting protrusion protruding from its top surface. A stepped surface 100 with a closed-loop structure is formed between the outer wall of the limiting protrusion and the outer wall of the limiting block 312. The upper template 32 has a limiting groove 200 recessed at a position corresponding to the limiting block 312, into which the limiting protrusion extends. The stepped surface 100 is in contact with the bottom surface of the upper template 32. The left end of the top surface of the lower template 31 has a strip-shaped protrusion protruding along the front-back direction, which allows the right end of the lower template 31 to be stacked on top. The top surface of the strip-shaped protrusion is on the same plane as the stepped surface 100. In application, the setting of the strip-shaped protrusion and the stepped surface allows the upper template 32 to be horizontally stacked on top of the lower template 31, so that the explosion-proof film and the touch screen panel can be subjected to more uniform force when they are bonded together.
