[0002] The mobile phone display is an important part of the smartphone. It is used to display images, text and other content, and is one of the main ways for users to interact with the mobile phone interface. Some mobile phones are designed with curved display screens. These curves can extend the screen to the edge of the phone and provide additional functions, such as quick access to applications or notifications. With the continuous evolution of mobile phone screens, curved screen technology has occupied a large share of the market. These mobile phone displays include display modules and curved glass. The protective film of tempered glass is attached to the curved glass through a screen bonding machine to protect the display screen.

In traditional mold bonding, the curved glass and tempered protective film are loaded with a loading structure. After the curved glass and tempered protective film are loaded into the bonding mold, they are bonded by a machine. During the bonding process, the loading structure is in a stopped state, which also leads to a long overall cycle and low bonding efficiency. Utility Model Content

[0033] See also Figures 1 to 3The embodiment of the present application provides a laminating device 100, which is provided with a pre-laminating station 301 and a pressing station 302 arranged at an interval from the pre-laminating station 301. The laminating device 100 can be used to laminate a first material sheet to a second material sheet 202, and both the first material sheet and the second material sheet 202 are in the form of thin sheets.

[0034] See also Figures 1 to 3 The laminating device 100 includes a first feeding structure 110, a second feeding structure 120, a material transfer structure 130 and a pressing structure 140. The first feeding structure 110 is used to transfer the first material sheet to the pre-laminating station 301; the first material sheet can be manually laid flat on the first feeding structure 110, and then the first material sheet is transferred to the pre-laminating station 301 by the first feeding structure 110. The second feeding structure 120 is used to pick up the second material sheet 202 from the material box, and transfer the second material sheet 202 flat to the pre-laminating station 301. The pressing structure 140 includes a rotating platform 142, a lower pressing mold 141 arranged on the rotating platform 142, and an upper pressing mold 144 used to cooperate with the lower pressing mold 141 and located above the lower pressing mold 141. The lower pressing molds 141 are arranged in plurality at intervals, one of which is pressed and matched with the upper pressing mold 144, and at least one of the lower pressing molds 141 is in a waiting state.

The material transfer structure 130 transfers the first material sheet to the top of the second material sheet 202, so that the first material sheet is pre-laminated with the second material sheet 202, and then the first material sheet and the second material sheet 202 are synchronously moved from the second feeding structure 120 to one of the lower pressing molds 141, so that the upper pressing mold 144 presses the lower pressing mold 141 on which the first material sheet and the second material sheet 202 are placed, thereby achieving lamination of the first material sheet and the second material sheet 202.

[0036] See also Figures 1 to 3 During the lamination process, the first feeding structure 110, the second feeding structure 120 and the material transfer structure 130 can feed the lower pressing mold 141 to be received, so that after the first and second material sheets 202 on the lower pressing mold 141 in front are pressed together, the lower pressing mold 141 with the first and second material sheets 202 at the back can continuously cooperate with the upper pressing mold 144 through the rotation of the rotating platform 142, thereby shortening the operation cycle of the laminating device 100 and improving the laminating efficiency.

[0037] It can be understood that the precision and reliability of the bonding between the first material sheet and the second material sheet 202 can be improved by the cooperation and pressing of the upper pressing mold 144 and the lower pressing mold 141 .

[0038] Optionally, the first material piece is a curved glass on a mobile phone display screen, and the second material piece 202 may be a protective film.

[0041] See also Figures 1 to 4 Optionally, the transfer adsorption holes 1231 are connected to a vacuum pump, and a plurality of transfer adsorption holes 1231 are arranged at intervals, and the second material sheet 202 is placed on the transfer material table 123, and each transfer adsorption hole 1231 positions the second material sheet 202 on the transfer material table 123 by negative pressure adsorption.

[0042] Optionally, the film is used to protect the second material sheet 202, and a lug is provided at one end of the film, the film tearing assembly 124 clamps the lug, the transfer table 123 absorbs the second material sheet 202 and slides toward the pre-lamination station 301, thereby separating the film from the second material sheet 202, and the film tearing assembly 124 collects the torn film into the collection box 127.

[0043] See also Figure 4 In some embodiments, the second feeding structure 120 also includes a film tearing gantry 122 located on the sliding path of the transfer table 123, and the film tearing assembly 124 includes a clamping mechanism 1245 for clamping the film and a lifting driver 1241 slidably arranged on the film tearing gantry 122 and used to drive the clamping mechanism 1245 to slide up and down, and the sliding direction of the lifting driver 1241 is perpendicular to the sliding direction of the transfer table 123.

[0044] See also Figures 4 to 5Optionally, the loading adsorption head 121121 and the film tearing assembly 124 are respectively slidably connected to the two sides of the film tearing gantry 122, which is conducive to the compactness of the overall structure of the bonding device 100. The collection box 127 is located on the sliding path of the lifting drive 1241. When the clamping mechanism 1245 clamps the film, the lifting drive 1241 slides to the collection box 127 and makes the clamping mechanism 1245 release the film from the collection box 127.

[0045] See also Figures 4 to 5 Optionally, the lifting driver 1241 drives the clamping mechanism 1245 to descend a certain distance, and at the same time, the lifting driver 1241 slides toward the transfer table 123 so that the lug on the diaphragm can horizontally enter the clamping mechanism 1245 to be clamped by the clamping mechanism 1245. At this time, the transfer table 123 drives the second material sheet 202 to slide toward the pre-lamination station 301, thereby separating the second material sheet 202 and the diaphragm.

[0046] See also Figures 4 to 5 It is understandable that the transfer table 123 can achieve reciprocating sliding through a ball screw and can achieve stable sliding through guide rails and sliders.

[0047] It can also be understood that the lifting drive 1241 can be a cylinder, and the lifting drive 1241 and the film tearing gantry 122 can also achieve reciprocating sliding through a ball screw, and can achieve stable sliding through the cooperation of a guide rail and a slider.

[0048] See also Figures 4 to 5 In some embodiments, the clamping mechanism 1245 includes a first clamping arm 1243 connected to the lifting driver 1241, a second clamping arm 1244 cooperating with the first clamping arm 1243, and a clamping driver 1242 driving the first clamping arm 1243 to move relative to the first clamping arm 1243.

[0049] Optionally, the upper end of the first clamp arm 1243 is connected to the lifting driver 1241, and the lower end of the first clamp arm 1243 cooperates with the second clamp arm 1244. When the lug is located between the first clamp arm 1243 and the second clamp arm 1244, the clamping driver 1242 drives the second clamp arm 1244 to move upward, so that the lug is clamped between the first clamp arm 1243 and the second clamp arm 1244. The clamping driver 1242 can also be a cylinder, and the second clamp arm 1244 is connected to the piston rod of the cylinder.

[0050] See also Figures 4 to 5In some embodiments, a positioning groove 1232 is provided on the transfer table 123, and a vacuum plate is provided on the positioning groove 1232. The vacuum plate is slidably arranged along the groove depth direction of the positioning groove 1232, and a plurality of positioning adsorption holes 1251 are provided on the surface of the vacuum plate facing the second material sheet 202. The positioning adsorption holes 1251 are connected to a vacuum pump and can be connected to the second material sheet 202 by negative pressure adsorption.

[0051] See also Figures 1 to 5 Optionally, the positioning plate 125 can also be slidably set in the positioning groove 1232 by a cylinder. When the material transfer structure 130 places the first material sheet on the second material sheet 202, the positioning plate 125 pushes the second material sheet 202 upward, and at the same time, the positioning adsorption hole 1251 adsorbs the second material sheet 202, so that the first material sheet and the second material sheet 202 are pre-bonded. The material transfer structure 130 then moves the pre-bonded first and second materials 202 as a whole to the lower pressing mold 141. It can be understood that after the first material sheet and the second material sheet 202 are pre-bonded, the transfer adsorption hole 1231 is disconnected from the vacuum pump, thereby facilitating the material transfer structure 130 to transfer the second material sheet 202.

[0055] Feedback system: Servo motors are usually equipped with a feedback system, such as an encoder or demodulator, to constantly monitor the position of the motor and make adjustments based on the feedback information to ensure accuracy.

[0056] High performance: Servo motors are typically able to provide high acceleration and fast response, making them suitable for applications that require rapid changes.

[0060] See also Figures 4 to 5 Optionally, the pressing driver 146 drives the opening edge of the pressing seat 143 to seal against the rotating platform 142, and selectively covers one of the lower pressing molds 141, so that one of the lower pressing molds 141 and the upper pressing mold 144 are both located in the vacuum chamber 1431, and then the vacuum chamber 1431 is evacuated to exhaust the air in the vacuum chamber 1431, thereby improving the fitting quality of the first sheet and the second sheet 202.
