Description

Technical Field

[0001] This application relates to the field of mobile phone glass cover film application technology, specifically to an anti-offset mechanism for applying film to mobile phone glass covers. Background Technology

[0002] In the production process of mobile phone glass covers, film application is a crucial step in ensuring product quality and appearance. With the rapid development of the mobile phone industry, higher demands are placed on the precision, efficiency, and stability of glass cover film application. However, current mobile phone glass cover film application technology has revealed many problems in practical operation.

[0003] Taking the automatic screen protector application mechanism for mobile phone glass covers disclosed in patent CN214824452U as an example, although it possesses certain automated screen protector application functions, it has significant defects in the conveying and positioning of the glass cover. When the glass cover moves towards the application area, the simple fixing method used in this mechanism makes it difficult to effectively resist vibrations generated during equipment operation and external interference during transport, causing the glass cover to easily shift position. This not only leads to deviations in the bonding position between the protective film and the glass cover, resulting in a significantly reduced application effect and problems such as bubbles and loose bonding, but in severe cases, it can even render the product unusable, thereby increasing production costs. Furthermore, some existing screen protector application equipment has an unreasonable design in its moving structure. When moving the glass cover, the friction between components is large, which not only accelerates the wear and tear of the equipment but may also further exacerbate the glass cover's shift due to jamming during movement.

[0004] In summary, existing mobile phone glass cover film application equipment has shortcomings in positioning stability and smooth movement, making it difficult to meet the demands of high-precision and high-efficiency film application production. Therefore, it is necessary to develop an innovative anti-deviation mechanism to ensure that the glass cover maintains a stable position throughout the film application process and achieves smooth and precise movement, thereby improving film application quality and production efficiency. Summary of the Invention

[0005] To address the aforementioned technical problems, this application solves the issue that during the application of screen protectors to mobile phone glass covers, the lack of an effective fixing and stable movement method easily leads to misalignment, affecting the accuracy and quality of the application.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: an anti-deviation mechanism for applying film to mobile phone glass covers, comprising a conveying component, an adsorption component, and a carrying component, wherein the carrying component slides on the conveying component, and the adsorption component is fixedly installed on the carrying component.

[0007] The conveying assembly includes a mounting base, an electric cylinder, a slide block, and a slide groove. The slide block is fixedly mounted on the mounting base and has four slide grooves. The electric cylinder is fixedly mounted on the mounting base, and its output end is fixedly connected to the adsorption assembly.

[0008] The adsorption assembly includes a front cover, a cavity, a rear cover, a connecting rod, and a piston. The cavity is fixedly mounted on the carrier assembly. The cavity has a communicating cavity with three connecting ports. The connecting port facing the carrier assembly is tightly connected to the carrier assembly. The piston slides on the cavity. The connecting rod is fixedly connected to the piston. The front cover and the rear cover are respectively installed on the connecting ports facing the electric cylinder and away from the electric cylinder. The rear cover is sealed to the cavity. The front cover has an exhaust port and a groove. The connecting rod slides on the groove of the front cover. The end of the connecting rod facing the electric cylinder is fixedly connected to the output end of the electric cylinder.

[0009] The supporting assembly includes a supporting plate, a horizontal mounting plate, a sliding frame, and a vertical mounting plate. The supporting plate is provided with two horizontal mounting plates and two vertical mounting plates. Each horizontal mounting plate is fixedly connected to a sliding frame by bolts. The two vertical mounting plates are respectively connected to the two end faces of the cavity by bolts. The supporting plate is provided with a groove for supporting the glass cover plate. The groove is provided with a through hole, which is connected to the communication port of the cavity.

[0010] Preferably, the bearing component includes a housing, a strong magnetic plate, and a rolling ball. The housing is fixedly mounted on the sliding frame. A groove is provided at one end of the sliding frame away from the sliding frame. The housing is mounted on the groove. The housing has a groove that matches the rolling ball. The rolling ball is mounted on the groove. The strong magnetic plate is kept in the installation state on the housing and the rolling ball is kept in the groove of the strong magnetic plate by the magnetic force of the strong magnetic plate itself.

[0011] Preferably, the supporting component includes breathable cotton, the groove depth of the supporting plate is less than the thickness of the glass cover plate, and the breathable cotton is installed in the groove to cushion the glass cover plate.

[0012] Preferably, the adsorption assembly includes a buffer plate and a spring. The buffer plate is slidably disposed in the cavity of the chamber and has holes for gas flow. The spring is disposed in the cavity of the chamber and its two ends are fixedly connected to the buffer plate and the rear cover, respectively. The spring force generates a counter-thrust force, which drives the adsorption assembly and the carrier assembly to move.

[0013] Preferably, the conveying assembly includes a mounting plate and a slide. Two mounting plates are fixedly installed on the mounting base and respectively fixed to the two ends of the electric cylinder. Two slides are provided and fixedly installed on the slide base, with one slide covering two slide grooves.

[0014] The technical solution provided in this application has the following advantages compared with the prior art:

[0015] 1. This application, by setting up an adsorption component, uses an electric cylinder to control the piston to slide within the cavity to create negative pressure. Combined with the breathable cotton in the groove of the support plate, it can quickly adsorb and fix the glass cover plate after it is placed, making it stable in the fixed position of the support plate. This achieves reliable positioning of the glass cover plate during the process of moving to the film application area and during the film application process, solving the problem of glass cover plate being prone to displacement in the prior art, and improving the accuracy and quality of film application.

[0016] 2. This application sets a housing, a strong magnetic plate, and a ball on the sliding frame of the load-bearing component. The ball cooperates with the semi-circular elongated groove of the slide block. The strong magnetic plate uses magnetic force to stabilize the load-bearing component on the slide block. When moving, the spherical structure of the ball reduces the direct contact area with the slide block, reduces friction, and realizes the smooth movement of the load-bearing component on the slide block. This solves the problems of large component wear and poor movement when the existing equipment moves, extends the service life of the mechanism, and improves the smoothness of the film application operation.

[0017] 3. This application uses an electric cylinder to drive the adsorption component and the carrier component to move back and forth on the slide. Combined with the adsorption component's adsorption and release function for the glass cover plate, it realizes the automated operation of the glass cover plate from placement, transportation to the film application area, and removal after film application. This solves the problems of excessive manual intervention and cumbersome operation in the traditional film application process and improves the overall film application efficiency.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0028] like Figures 1 to 7 As shown, an anti-deviation mechanism for applying film to mobile phone glass covers includes a conveying assembly 100, an adsorption assembly 200, and a supporting assembly 300. The supporting assembly 300 slides on the conveying assembly 100, and the adsorption assembly 200 is fixedly mounted on the supporting assembly 300. The conveying assembly 100 is installed below the film application mechanism. The glass cover is placed on the supporting assembly 300, and the adsorption assembly 200 adsorbs the glass cover to prevent deviation. Then, the adsorption assembly 200 and the supporting assembly 300 are controlled to slide on the conveying assembly 100, moving to the film application area. After the film application is completed, the adsorbed glass cover is removed and released.

[0029] like Figure 1 As shown, the conveying assembly 100 includes a mounting base 101, an electric cylinder 103, a slide block 104, and slide grooves 105. The slide block 104 is fixedly mounted on the mounting base 101, and four slide grooves 105 are provided on the slide block 104. The slide grooves 105 are semi-circular elongated grooves. The electric cylinder 103 is fixedly mounted on the mounting base 101, and the output end of the electric cylinder 103 is fixedly connected to the adsorption assembly 200. The electric cylinder 103 controls the reciprocating movement of the adsorption assembly 200 and the carrier assembly 300 on the slide block 104.

[0030] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the adsorption assembly 200 includes a front cover 201, a cavity 202, a rear cover 203, a connecting rod 204, and a piston 205. The cavity 202 is fixedly installed on the support assembly 300. The cavity 202 has a communicating cavity with three communicating ports. The communicating port facing the support assembly 300 is tightly connected to the support assembly 300 and is equipped with a sealing ring and other structures to ensure sealing performance. The piston 205 slides on the cavity, and the connecting rod 204 is fixedly connected to the piston 205. The front cover 201 and the rear cover 203 are respectively installed on the communicating ports facing the electric cylinder 103 and away from the electric cylinder 103 on the cavity 202. The rear cover 203 is sealed to the cavity 202. A rubber block is provided on the rear cover 203 to block the communicating port of the cavity 202. The rear cover 203 is also provided with a fastening plate that contacts the outer wall of the cavity 202 and is fixedly connected to the cavity 202 by bolts. The front cover 201 is provided with an exhaust port and a sliding groove. The front cover 201 is also provided with a fastening plate, which is connected to the outer wall of the cavity 202 and fixedly connected to the cavity 202 by bolts. The connecting rod 204 passes through the sliding groove of the front cover 201. The end of the connecting rod 204 facing the electric cylinder 103 is fixedly connected to the output end of the electric cylinder 103. Under the control of the electric cylinder 103, the connecting rod 204 slides on the sliding groove of the front cover 201, and drives the piston 205 to slide in the cavity of the cavity 202, driving the gas flow to form the adsorption and release of the glass cover plate on the bearing assembly 300.

[0031] like Figures 2 to 7 As shown, the support assembly 300 includes a support plate 301, a horizontal mounting plate 302, a sliding frame 303, and a vertical mounting plate 308. The support plate 301 has two horizontal mounting plates 302 and two vertical mounting plates 308. The two horizontal mounting plates 302 are located on the two side end faces of the support plate 301 and are horizontally positioned, while the two vertical mounting plates 308 are located on the lower end face of the support plate 301 and are vertically positioned. Each horizontal mounting plate 302 is fixedly connected to a sliding frame 303 by bolts, and the two vertical mounting plates 308 are connected to the two end faces of the cavity 202 by bolts. The support plate 301 has a groove for supporting a glass cover plate, and this groove has a downward through hole connected to the communication port of the cavity 202. This through hole allows the glass cover plate placed in the groove to be held in place on the support plate 301, preventing displacement during movement to the film application area and during the film application process.

[0032] like Figure 3As shown, the bearing assembly 300 includes a housing 304, a strong magnetic plate 305, and a ball 306. The housing 304 is fixedly mounted on the sliding frame 303. A groove is provided at one end of the housing 304 away from the sliding frame 303, and the housing 304 is mounted on the groove. A semi-circular groove matching the ball 306 is provided on the housing 304, and the ball 306 is mounted on the groove. The installation state of the strong magnetic plate 305 on the housing 304 and the installation state of the ball 306 on the groove of the strong magnetic plate 305 are maintained by the magnetic force of the strong magnetic plate 305 itself. Both the housing 304 and the strong magnetic plate 305 are rectangular structures, while the rolling ball 306 is spherical. The rolling ball 306 is set in the semi-circular elongated groove of the slide 105. Through the rolling ball 306, a certain gap is maintained between the strong magnetic plate 305 and the slide 104. Thus, the magnetic force of the strong magnetic plate 305 stabilizes the position of the bearing component 300 and the adsorption component 200 on the slide 104. When moving, since there is no direct contact with the slide 104, it is easy to move. During movement, the spherical structure of the rolling ball 306 reduces the friction with the slide 104, reduces wear, and thus facilitates movement.

[0033] like Figure 2 , Figure 4 and Figure 6 As shown, the supporting component 300 includes breathable cotton 307. The groove depth of the supporting plate 301 is less than the thickness of the glass cover plate. The breathable cotton 307 is installed in the groove, and the breathable cotton 307 cushions the glass cover plate. When the piston 205 in the cavity 202 moves rapidly towards the electric cylinder 103, the piston 205 drives the gas to move. Utilizing the porous structure and elastic properties of the breathable cotton 307 itself, the gas under the glass cover plate enters the cavity of the cavity 202 through the through hole of the supporting plate 301, thereby forming a negative pressure that adsorbs the glass cover plate. The glass cover plate presses down on the breathable cotton 307, causing the breathable cotton 307 to deform under pressure. The porous structure of the breathable cotton 307 is sealed, thus preventing external gas from entering the cavity of the cavity 202 through the through hole of the groove in the supporting plate 301. This fixes the glass cover plate, ensuring that it is stably installed in the fixed position on the supporting plate 301. This prevents the glass cover plate from shifting due to external influences during subsequent film application, thus ensuring the film application effect is not affected.

[0034] like Figure 6 and Figure 7As shown, the adsorption assembly 200 includes a buffer plate 206 and a spring 207. The buffer plate 206 is slidably disposed in the cavity of the chamber 202 and has multiple holes for gas flow. The spring 207 is disposed in the cavity of the chamber 202 and its two ends are fixedly connected to the buffer plate 206 and the rear cover 203, respectively. The spring force of the spring 207 forms a counter-thrust force, which drives the adsorption assembly 200 and the carrier assembly 300 to move. When piston 205 moves away from electric cylinder 103 within the cavity of chamber 202, piston 205 pushes gas out through the through hole in the groove of bearing plate 301, pushing the glass cover to release its fixation. The breathable cotton 307 returns to its fluffy state. During this process, piston 205 will contact buffer plate 206. After contact, piston 205 continues to move, pushing buffer plate 206 to move. Buffer plate 206 then compresses spring 207. When the elastic force of spring 207 reaches a certain level, the elastic force of spring 207 overcomes the magnetic force of strong magnetic plate 305. Thus, piston 205 can push buffer plate 206, thereby pushing adsorption component 200 and bearing component 300 to slide on slide block 104, moving the glass cover out of the film application area for replacement, and repeating the operation.

[0035] like Figure 1 As shown, the conveying assembly 100 includes a mounting plate 102 and a slide 106. Two mounting plates 102 are fixedly mounted on the mounting base 101 and are respectively fixed to the two ends of the electric cylinder 103, thus fixing the electric cylinder 103 to the mounting base 101 via the mounting plates 102. Two slides 106 are provided, both fixedly mounted on the slide block 104. The slide 106 has a frame structure, with one slide 106 covering two slide grooves 105. The inner wall of the slide 106 matches the rectangular structure of the housing 304, thereby preventing the housing 304 from shaking and ensuring the stable movement of the bearing assembly 300.

[0036] Working principle:

[0037] The load-bearing component 300 is magnetically attached to the slide block 104 by the strong magnetic plate 305, which prevents the load-bearing component 300 from shaking randomly. However, the magnetic force is limited and will not have a significant impact on the movement of the load-bearing component 300. It requires a certain force to move, but not a large one, so air pressure and elasticity can be used to overcome the magnetic force.

[0038] First, place the glass cover plate on the breathable cotton 307 of the support plate 301, aligning the corner of the glass cover plate with the through hole of the support plate 301. That is, the two sides of one corner of the glass cover plate are in contact with the two sides of the corner of the through hole in the groove of the support plate 301, thereby unifying the fixed position of the glass cover plate.

[0039] Then, the electric cylinder 103 is activated. The output end of the electric cylinder 103 controls the connecting rod 204 to slide on the front cover 201 towards the electric cylinder 103. The connecting rod 204 pulls the piston 205 to slide in the cavity of the chamber 202, thereby driving the gas flow. The piston 205 pushes some gas out from the exhaust port of the front cover 201, and through the through hole of the support plate 301 and the porous structure of the breathable cotton 307, it drives the gas between the glass cover and the support plate 301 into the cavity of the chamber 202, thereby forming a negative pressure. This causes the glass cover to squeeze the breathable cotton 307 downward, causing the breathable cotton 307 to be deformed and unable to flow gas. When this happens, the piston 205 continues to move, ensuring that the glass cover and the breathable cotton 307 are in complete contact with the bottom surface of the groove of the support plate 301, avoiding gas leakage inside the chamber 202, which would weaken or release the fixing ability of the glass cover.

[0040] After the glass cover is fixed, no new gas enters the cavity of the chamber 202. As a result, the connecting rod 204 continues to be pulled. Due to the presence of air pressure between the piston 205 and the rear cover 203, the pressure is greater than the magnetic force of the strong magnetic plate 305. Pulling the connecting rod 204 will cause the adsorption component 200 and the bearing component 300 to slide on the slide block 104 as a whole, thereby moving the glass cover on the bearing plate 301 to the film application area for film application.

[0041] After the film is applied, the electric cylinder 103 is reversed, pushing the connecting rod 204 away from the electric cylinder 103. This causes the connecting rod 204 to push the piston 205 closer to the back cover 203, and forces the gas between the piston 205 and the back cover 203 through the through-hole in the support plate 301 into the space between the support plate 301 and the breathable cotton 307, thus releasing the glass cover and canceling the alignment. When the piston 205 contacts the buffer plate 206, further pushing the piston 205 compresses the spring 207. Once the spring force of the spring 207 reaches a certain level, it exceeds the magnetic force of the strong magnetic plate 305. Therefore, pushing the connecting rod 204 can move the adsorption assembly 200 and the support assembly 300 back to their initial positions on the slide 104, allowing for the replacement of the glass cover.

[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
