Description

Technical Field

[0001] This utility model relates to the field of touch screen bonding technology, and in particular to a bonding and feeding device for explosion-proof film. 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 loading of the film and unloading of the finished product at station one. On the one hand, manual loading of the film is inefficient. On the other hand, station two can only be started after station one is completed. Manual loading of the film and unloading of the finished product are required simultaneously, resulting in many manual operation steps and low production efficiency.

[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. Summary of the Invention

[0005] The purpose of this invention is to provide a bonding and feeding device for explosion-proof film to solve the problems of low production efficiency and low feeding efficiency of existing bonding machines.

[0006] To achieve its purpose, this utility model adopts the following technical solution: A device for laminating and feeding explosion-proof films includes a frame and a film feeding device. The film feeding device has a film placement device and a film transfer device, with the film transfer device mounted on the frame. The film placement device has a placement seat for stacking several explosion-proof films. The placement seat is provided with several circumferentially arranged positioning members, each positioning member forming a receiving space for accommodating the explosion-proof films. The positioning members are mounted on the placement seat in a manner that allows them to translate towards the center of the receiving space. The placement seat is located at the upper part of the receiving space and is provided with a separation device that can separate the films on the film transfer device. The film transfer device is mounted on the frame in a manner that allows it to move up and down and to translate laterally between the receiving space and the positioning fixture.

[0007] With the film transfer device moving laterally in the left-right direction, the placement seat is located on the top left end of the frame, and the frame is provided with a mounting frame extending in the left-right direction on the rear side of the placement seat. The film transfer device has a film transfer head, which is mounted on the front side of the mounting frame in a manner that allows it to move left and right, up and down, forward and backward, and rotate circumferentially.

[0008] 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.

[0009] 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 separation device mentioned above.

[0010] The top surface of the frame has a detection window on the right side of the placement seat. The detection window is located below the front right end of the mounting frame. 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.

[0011] 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.

[0012] 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.

[0013] This invention relates to a device for laminating and feeding explosion-proof films. In application, several explosion-proof films are stacked within a receiving space. Positioning components are controlled to move relative to the center of the receiving space until they clamp the explosion-proof films within the space. A film-shifting device is then activated, moving to the top surface of each explosion-proof film and lifting it upwards. A separation device prevents the film-shifting device from simultaneously lifting multiple films. The film-shifting device then moves towards a positioning fixture, placing the explosion-proof films onto the fixture. Compared to existing technologies, this method uses a film-shifting device to automatically feed the explosion-proof films onto the positioning fixture, resulting in more precise feeding and higher production efficiency. It eliminates the need for manual feeding, reducing manual operation steps and improving production efficiency. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0015] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0016] A device for laminating and feeding explosion-proof film, such as Figure 1As shown, the device includes a frame 1 and a film feeding device. The film feeding device has a film placement device and a film transfer device, with the film transfer device mounted on the frame 1. The film placement device has a placement seat 2 for stacking several explosion-proof films. The placement seat 2 is provided with several circumferentially arranged positioning members 3, each positioning member 3 forming a receiving space for each explosion-proof film. The positioning members 3 are mounted on the placement seat 2 in a manner that moves towards the center of the receiving space. The placement seat 2 is located at the upper part of the receiving space and is provided with a separation device for separating the explosion-proof films on the film transfer device. Specifically, the frame 1 has a mounting frame 4 extending in the left-right direction on the rear side of the placement seat 2. The mounting frame 4 has a horizontal beam 41 and a vertical beam 42. There are two vertical beams 42, which are spaced apart from each other. The horizontal beam 41 extends in the left-right direction above the two vertical beams 42. The placement seat 2 is located on the top left end of the frame 1. The placement seat 2 has several positioning members 3. The device has a lower mounting plate 21 and an upper placement plate 22. The lower mounting plate 21 is locked to the left end of the top surface of the frame 1. The top surface of the lower mounting plate 21 has a locking hole that runs vertically through it. The top surface of the frame has a locking groove corresponding to the position of the locking hole. The lower mounting plate 21 is locked to the frame by a locking bolt passing through the locking hole and into the locking groove. The lower mounting plate 21 is located below the front side of the crossbeam 41. The upper placement plate 22 is located above the lower mounting plate 21. The positioning member 3 has a number of positioning blocks that are spaced around the upper placement plate 22 in the circumferential direction. The top surface of the upper placement plate 22 and each positioning block form the above-mentioned accommodating space with an open top surface, in which a number of explosion-proof diaphragms are stacked in sequence. Each positioning block is installed on the lower mounting plate 21 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.The positioning blocks are provided in four parts. The four positioning blocks include a left limiting block 31 on the left side of the upper placement plate 22, a front limiting block 32 on the front side of the upper placement plate 22, a right limiting rod 33 on the right side of the upper placement plate 22, and a rear limiting plate 34 on the rear side of the upper placement plate 22. The upper placement plate 22 is mounted on the lower mounting plate 21 in a way that allows it to move up and down, i.e., the upper placement plate 22 is suspended above the lower mounting plate 21. A movable cylinder (not shown in the figure) is provided inside the frame 1. The output end of the movable cylinder extends upward beyond the lower mounting plate 21, and the end of the movable cylinder is connected to the upper placement plate. A left extension groove is recessed on the left side of the upper placement plate 22, allowing the left limiting block to extend into it. The left limiting block 31 and the front... All limiting blocks 32 are vertically arranged blocks. On the side of the vertical block facing away from the upward-facing plate 22, there is a mounting post 221 vertically arranged on the lower mounting plate 21. The vertical block is mounted on the mounting post 221 in a manner that allows it to move towards or away from the upward-facing plate 22. That is, the mounting post 221 has vertical and horizontal blocks arranged perpendicularly to each other. The vertical block is vertically arranged outside the side of the vertical block facing away from the upward-facing plate 22. The vertical block of the left limiting block 31 is located in the left extension groove, and the horizontal block is located at the lower end of the side of the vertical block facing away from the vertical block. The vertical block is locked to the lower mounting plate 21. Several adjusting rods 2211 are provided on the vertical block, with one end connected to the vertical block and the other end extending out of the vertical block. Each adjusting rod 2211 is spaced apart in the vertical direction. The outer wall of 211 is provided with external threads, and a screw block is screwed onto the end of the adjusting rod 2211 facing away from the vertical block; the right limiting rod 33 is vertically set, and the right limiting rod 33 is vertically installed on the lower mounting plate 21 in a manner that allows it to move left and right toward the upper placement plate 22, that is, the right limiting rod 33 has a material stop rod and a fixing rod arranged perpendicularly to each other. The right side of the upper placement plate 22 is recessed with a right extension groove that extends vertically, and the material stop rod is vertically set in the right extension groove. The lower end of the material stop rod is connected to the fixing rod. The fixing rod extends along the left and right direction on the lower mounting plate 21, and a strip-shaped through hole that extends along the left and right direction and extends vertically is opened on the fixing rod. The lower mounting plate 21 is recessed within the range of the strip-shaped through hole and has a locking groove. The locking bolt passes through the strip-shaped through hole to the locking groove and is locked together with the lower mounting plate 21. The strip-shaped through hole facilitates the left and right movement of the right limiting rod 33. The top surface of the rear limiting plate 34 is provided with a brush 341, one end of which is locked together with the rear limiting plate 34, and the other end of which faces the accommodating space and extends in the left and right direction. The front end of the brush extends into the accommodating space. The brush 341 is the separation device mentioned above. The way the rear limiting plate 34 moves toward the accommodating space is similar to that of the front limiting block 32. In actual application, one of its positioning blocks can be fixed on the lower mounting plate 21, and the other three positioning blocks can move relative to the accommodating space. This can also be used to position the explosion-proof diaphragm and to apply explosion-proof diaphragms of different sizes.In application, adjust the positioning blocks to move towards the accommodating space until they clamp the explosion-proof diaphragms. This involves stacking several explosion-proof diaphragms within the accommodating space. Adjust the front limit block 32, left limit block 31, and rear limit plate 34 to the desired positions. Secure the locking block to the adjusting rod, adjust the right limit rod 33 to the desired position, and then tighten the locking bolts. This adjusts the accommodating space. The positioning blocks can move relative to the accommodating space, allowing adjustment of the space's inner diameter. This facilitates the placement of explosion-proof diaphragms of different sizes. Furthermore, when removing the top layer of explosion-proof diaphragms, the brush separates it from the others, making it easy to remove individual diaphragms.

[0017] The film transfer device is mounted on the frame 1 in a manner that allows it to move up and down and laterally along the accommodating space to the positioning fixture. Specifically, the positioning fixture is located outside the right end of the placement seat 2 and is positioned opposite to the placement seat 2. The film transfer device has a film transfer head 5, 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 61 that can move up and down, and a front moving plate 62 that can move left and right along the rear moving plate 61 is provided on the front side of the rear moving plate 61. The bottom surface of the front moving plate 62 has a protrusion extending from the rear moving plate 61. A lower moving plate 63 is provided, which can move back and forth along the bottom surface of the front moving plate 62. The film transfer head 5 is mounted on the bottom surface of the lower moving plate 63 in a circumferentially rotatable manner. That is, the front side of the crossbeam 41 is provided with a first slide rail 411 extending in the vertical direction at the position corresponding to the position of the rear moving plate 61. The rear side of the rear moving plate 61 is provided with a first slider (not shown in the figure) that slides with the first slide rail 411. The front side of the crossbeam 41 is provided above the first slide rail 411 and is provided with a first cylinder (not shown in the figure) that drives the first slider to move up and down. The output end of the first cylinder is connected to the first slider. The front side of the rear moving plate 61 is provided with a left-right direction... An extended second slide rail 611 is provided. A second slider that slides in cooperation with the second slide rail 611 is provided on the rear side of the front moving plate 62. A second cylinder that drives the second slider to move left and right is provided on the crossbeam 41 outside the left end of the second slide rail 611. The output end of the second cylinder is connected to the second slider. A third slide rail is provided on the top surface of the lower moving plate 63. A third slider that slides in cooperation with the third slide rail is provided on the bottom surface of the front moving plate 62. A third cylinder that drives the third slider to move back and forth is provided on the top surface of the lower moving plate 63 behind the third slide rail. The output end of the third cylinder is connected to the third slider. A vertically mounted rotary knob is provided on the top surface of the lower moving plate 63. The output end of the rotating motor 631 extends downward beyond the lower moving plate 63 and is connected to the film transfer head 5. The film transfer head 5 is a transparent block, and the bottom surface of the film transfer head 5 has several vacuum nozzles evenly spaced along the circumferential direction of the film transfer head 5. The method by which the film transfer head 5 picks up the explosion-proof film through the vacuum nozzles is a well-known technology to those skilled in the art and will not be described in detail here. The top surface of the film transfer head 5 is provided with a light source that is connected to the lower moving plate 63 and can transmit light downward from the film transfer head 5. The light emission method of the light source and the movement method of the film transfer head 5 are well-known technologies to those skilled in the art and will not be described in detail here.In application, activating the first cylinder moves the film transfer head 5 up and down, activating the second cylinder moves the film transfer head left and right, activating the third cylinder moves the film transfer head 5 back and forth, and activating the rotary motor rotates the film transfer head 5 circumferentially. Driving the film transfer head 5 to directly above the receiving space, activating the first cylinder moves the film transfer head 5 downward and lifts it through the vacuum nozzle. Activating the first cylinder again moves the film transfer head upward. During the lifting process from the receiving space, the brush ensures that the vacuum nozzle can lift a single explosion-proof diaphragm each time. Activating the second cylinder moves the film transfer head 5 to the right to the position where the explosion-proof diaphragm is placed on the positioning fixture. If the lifted explosion-proof diaphragm 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 diaphragm. Activating the first cylinder again moves the film transfer head 5 downward, placing the explosion-proof diaphragm on the positioning fixture.

[0018] This novel explosion-proof film laminating and feeding device, in application, involves a positioning fixture moving to the right side of the placement seat and being positioned opposite it. Several explosion-proof films are stacked within the receiving space. The positioning components are controlled to move relative to the center of the receiving space to clamp the explosion-proof films within the space. The film-transferring device is activated, and the film-transferring head moves to the top of the receiving space. The film-transferring head then moves down to the top surface of each explosion-proof film and lifts it upwards through a vacuum nozzle. The film-transferring head places the explosion-proof film at the position where the positioning fixture should have placed it. Compared to existing technologies, the film-transferring device automatically feeds the explosion-proof films onto the positioning fixture, resulting in more precise feeding and higher production efficiency. It eliminates the need for manual feeding, reducing manual operation steps and improving production efficiency. Furthermore, the placement seat 2 can hold several explosion-proof films, eliminating the need for repeated manual feeding.

[0019] In this invention, preferably, a detection window is provided on the top surface of the frame 1 on the right side of the placement seat 2. The detection window is located between the positioning fixture and the placement seat 2 and below the film transfer head 5. A transparent sealing cover 7 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 is aligned with 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 5 is aligned is a technique known to those skilled in the art. In application, the film transfer head takes out a single explosion-proof film from the receiving space, passes it through the detection window, and the visual inspection device performs the inspection. After the inspection is completed, if the position of the explosion-proof film is deviated, the first cylinder, the second cylinder, the third cylinder, or the rotating motor is activated to adjust the position of the film transfer head 5 so that the explosion-proof film can be aligned and placed into the positioning fixture.
