Description

TECHNICAL FIELD

[0001] The application relates to the technical field of frame bonding, in particular to a frame bonding tool for a touch screen. BACKGROUND

[0002] The frame bonding tool for a touch screen is mainly used for realizing frame bonding between a touch screen and a display screen. Frame bonding, also known as mouth-shaped adhesive bonding, is a simple bonding method, which fixes the four edges of the touch screen and the display screen by double-sided adhesive tape. This method is simple in process and low in cost, but may cause an air layer between the display screen and the touch screen, affecting the display effect. Despite this, the frame bonding tool is still widely used in some application scenarios due to its simple operation and cost-effectiveness.

[0003] For example, the patent with the publication number CN211669466U specifically discloses a plastic frame adhesive detection tool. When the second cylinder drives the pressure head mechanism to move downward, the first cylinder starts to press on the pressure sensor after reaching the position. The pressure sensor drives the pressing plate to press and attach the adhesive film and the plastic frame through the guide column guide sleeve. The guide column guide sleeve can guide and limit the fixed plate, effectively solving the problem of uneven force during manual adhesive application, which leads to poor adhesive effect.

[0004] In the actual frame bonding process, the accurate alignment of the touch screen and the display screen is the basis for ensuring the accuracy of touch control. If the two are offset, the user's touch operation will not be accurately mapped to the display screen, resulting in touch failure or misoperation. The offset between the touch screen and the display screen may also cause display abnormalities, such as picture distortion, color distortion, etc., which seriously affect the display effect.

[0005] Therefore, it is necessary to provide a frame bonding tool for a touch screen to solve the above problems.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] like Figures 1-2 As shown, this application provides a frame mounting fixture for a touch screen, including a base 1 and an operation plate 2 fixedly mounted on the upper end of the base 1. In order to enable the frame mounting operation of the touch screen and the display screen, a frame mounting mechanism 3 is provided on the upper end of the operation plate 2. The frame mounting mechanism 3 includes multiple sets of guide posts 30 fixedly mounted on the upper end of the operation plate 2, and a fixing plate 31 is fixedly mounted on the top of the guide posts 30. At the same time, a first cylinder 32 is fixedly mounted on the upper end of the fixing plate 31.

[0035] Meanwhile, a sliding plate 34 is slidably arranged on the guide post 30, and the output end of the first cylinder 32 passes through the fixed plate 31 and is fixedly connected to the sliding plate 34, so that the first cylinder 32 can drive the sliding plate 34 to move vertically up and down along the guide post 30.

[0036] In order to smoothly perform the frame bonding operation between the touch screen and the display screen, a second cylinder 33 is fixedly installed on both sides of the output end of the first cylinder 32 on the sliding plate 34. The output end of the second cylinder 33 passes through the sliding plate 34 and is fixedly connected to the pressure plate 35 so as to press the touch screen and the display screen, thereby achieving the effect of complete frame bonding.

[0037] like Figure 1 and Figures 3-4 As shown, in order to enable the touch screen and display screen to perform preliminary frame bonding operations and to perform pressing operations smoothly, a conveying mechanism 4 is provided on the operation panel 2. The conveying mechanism 4 includes slide rails 40 fixedly installed on both sides of the upper end of the operation panel 2, a slider 47 is slidably installed on the slide rails 40, and a mounting plate 45 is fixedly installed on the upper end of the slider 47.

[0038] Meanwhile, a through hole 41 is provided on the operation plate 2 between the two slide rails 40, and a hydraulic cylinder 42 is fixedly installed at the lower end of the operation plate 2. The output end of the hydraulic cylinder 42 passes through the through hole 41 and is fixedly connected to the lower end of the mounting plate 45, so that the mounting plate 45 can be driven to move along the slide rail 40 by starting the hydraulic cylinder 42.

[0039] To ensure the stability of the touchscreen and display screen during the initial frame mounting and conveying processes to the holding stage, preventing them from shifting, a positioning component 46 is provided on the mounting plate 45 (e.g., ...). Figure 4 As shown), the positioning component 46 includes multiple sets of slide rods 462 fixedly disposed on the upper end of the mounting plate 45, and a support plate 461 is slidably disposed on the slide rods 462;

[0040] Meanwhile, a third cylinder 460 is fixedly installed at the lower end of the mounting plate 45, and the output end of the third cylinder 460 passes through the mounting plate 45 and is fixedly connected to the abutment plate 461, so that the third cylinder 460 can drive the abutment plate 461 to move vertically up and down along the slide bar 462.

[0041] Furthermore, a positioning plate 463 is fixedly installed at the top of the slide bar 462. The positioning plate 463 is used to place the touch screen and the display screen. Multiple positioning holes 464 are opened on the edge of the positioning plate 463 to facilitate the positioning of the touch screen and the display screen.

[0042] Meanwhile, in order to position it, a positioning block 467 is rotatably provided at the lower end of the positioning plate 463, directly below the positioning port 464. One end of the positioning block 467 passes through the positioning port 464 and extends to the upper end of the positioning plate 463, so as to position the touch screen and display screen on the upper end of the positioning plate 463.

[0043] Furthermore, the other end of the positioning block 467 is inclined and hinged to the abutment plate 461 at the other end of the positioning block 467. Thus, when it is necessary to position the touch screen and the display screen, the abutment plate 461 can be driven to move vertically downward by the third cylinder 460, thereby driving the upper end of the positioning block 467 to continuously approach the positioning port 464, so as to position the touch screen and the display screen placed on the positioning plate 463.

[0044] When it is necessary to unlock it, simply drive the support plate 461 to move vertically upward. At this time, the upper end of the positioning block 467 will continuously move away from the positioning port 464, thereby achieving the purpose of unlocking.

[0045] When performing the frame application operation, the staff can first perform the preliminary frame application on the positioning plate 463. After the preliminary frame application is completed, it can be positioned by the positioning component 46. Then, the hydraulic cylinder 42 can be activated to push the touch screen and display screen that have completed the preliminary frame application to move along the slide rail 40 to the lower end of the pressure plate 35.

[0046] Meanwhile, to prevent external dust from entering the work station during the pressing process, sealing plates 38 are fixedly installed around the sliding plate 34, and corresponding slots 48 are opened on the mounting plate 45. In addition, to facilitate observation of the pressing situation, a transparent window 39 is opened on one side of the sealing plate 38. When the pressing operation begins, the first cylinder 32 pushes the sliding plate 34 to drive the sealing plate 38 into the slot 48. After the sealing plate is inserted, the second cylinder 33 can push the pressing plate 35 closer to the touch screen and the display screen until the touch screen and the display screen frame are in contact, which completes the pressing operation.

[0047] 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.
