Description

Technical Field

[0001] The utility model relates to the technical field of touch screen manufacturing, in particular to a pressure head structure which is convenient to switch. Background Art

[0002] A touch screen, also known as a "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connection devices according to a pre-programmed program. It can be used to replace mechanical button panels and create vivid audio and video effects through the LCD display.

[0003] In the touch screen manufacturing industry, there is a process of binding the touch sensor glass to the FPC. A pressure head is needed for pressing during binding. Before binding, a suitable pressure head needs to be selected, that is, it will be selected according to the width of the binding position. The purpose is that if the width of the pressure head is too large or too small, it will affect the binding effect. Therefore, when the pressure head is not suitable, it needs to be replaced. Before replacing the binding pressure head, a series of processes such as cooling down, removing the pressure head, installing the new pressure head and then heating up are required. The operation is relatively cumbersome and has a certain impact on production efficiency.

[0004] Therefore, in response to the above-mentioned situation, we have designed a pressure head structure that is easy to switch. Utility Model Content

Active cavities 201 are provided on both sides of the inner cavity of the fixed block 2. The active cavity 201 is connected with the locking groove 203 through the through hole 202. The design of the through hole 202 can facilitate the movement of the push rod 403, thereby facilitating the contact with the locking block 11; unlocking components 4 are provided on the left and right sides of the fixed block 2, and the unlocking components 4 include a push rod 401, a push plate 402, a push rod 403 and a return spring 404. The push rod 403 is placed in the active cavity 201 and one end passes through the through hole 202 and fits on the surface of the locking block 11. The end of the push rod 401 away from the push plate 402 is fixedly connected with a rubber pad, and the rubber pad is designed to be a disc structure. By arranging a rubber pad at one end of the push rod 401, it is convenient for the staff to press, reduce discomfort, and improve the comfort during pushing.

[0028] See also Figure 4-5 In this embodiment, the push plate 402 is slidably connected in the active cavity 201, one end of the push rod 401 is fixed on the push plate 402, and the other end movably passes through the fixed block 2, a return spring 404 is sleeved on the push rod 403, and the other end of the push rod 403 is fixed on the push plate 402, and the two ends of the return spring 404 are respectively fixed on the push plate 402 and the inner wall of the active cavity 201.

[0029] Specifically, the push plate 402 can move in the movable cavity 201 through the push of the push rod 401, so as to push the push rod 403 to push the lock block 11, and when the push plate 402 is moving, it can synchronously squeeze the return spring 404, so that when no thrust is applied to the push rod 401 in the later stage, the restoring force of the return spring 404 can be used to push the push plate 402 back to its original position, thereby driving the push rod 403 to return to its initial position.

[0030] See also Figure 2-4 In this embodiment, a limiting ring 301 is fixedly sleeved on the rod body of the rotating column 3 and at a position away from the locking block 11 , a limiting groove 101 is provided in the inner cavity of the mounting frame 1 , and the limiting ring 301 is slidably connected in the limiting groove 101 .

[0031] Specifically, through the design of the limiting ring 301 and the limiting groove 101, a supporting and limiting function can be provided to the rotating column 3, so that the vertical position of the rotating column 3 does not change, and the rotating column 3 can be made more stable on the mounting frame 1.

[0032] See also Figure 2 and Figure 4 In this embodiment, a pressure block 7 is installed on the top of each of the two pressure heads 6, and the widths of the two pressure blocks 7 are different. Grooves 601 are provided on both sides of the bottom of each pressure block 7. A locking screw 602 is threadedly penetrated in the groove 601. One end of the locking screw 602 penetrates the pressure head 6 and is threadedly connected to the bottom of the fixing plate 5. The screw head of the locking screw 602 is a hexagonal nut, and the thickness of the screw head is less than the depth of the groove 601.

[0033] Specifically, two pressure heads 6 of different widths can be used to adapt to binding positions of different widths, and the detachable design of the pressure block 7 can facilitate the subsequent disassembly of the pressure block 7, thereby realizing the maintenance of the pressure block 7 and the pressure head 6, and also facilitating the subsequent replacement of the entire pressure head 6.

[0034] See also Figure 2 and Figure 5 In this embodiment, one end of the push rod 403 close to the locking block 11 is designed to be a round head structure, and one end of the locking block 11 close to the push rod 403 is designed to be an arc structure.

[0035] Specifically, the round head design of the push rod 403 can facilitate contact with the locking block 11, and the arc design of the locking block 11 can facilitate the locking block 11 to slide out of the locking groove 203 to avoid getting stuck.

[0036] See also Figure 3-4 In this embodiment, the two telescopic chambers 8 are opened in mirror images, and the two locking grooves 203 are also opened in mirror images. The size of the locking groove 203 is adapted to the size of the locking block 11.

[0037] Specifically, the two telescopic chambers 8 are mirrored so that the two telescopic chambers 8 are on the same straight line, which ensures that the two locking blocks 11 are on a line of 180 degrees. Similarly, the two locking grooves 203 are mirrored so that the two locking grooves 203 are on a line of 180 degrees. When the two locking blocks 11 rotate 180 degrees, their positions are swapped, thereby facilitating entry into the locking grooves 203, thereby ultimately achieving a 180-degree rotation of the two pressing heads 6.

[0038] See also Figure 5 In this embodiment, the surface of the movable plate 10 is a smooth mirror structure, the inner wall of the telescopic cavity 8 is a smooth tight structure, and the movable plate 10 is slidably connected to the inner wall of the telescopic cavity 8.

[0039] Specifically, the movable plate 10 and the telescopic cavity 8 are both designed to be smooth mirror structures, which is conducive to smoother sliding of the movable plate 10 in the telescopic cavity 8.

[0040] When in use, when it is necessary to exchange the positions of the two pressure heads 6, the staff can first press the two push rods 401, thereby using the push rod 401 to push the push plate 402, and using the push plate 402 to push the push rod 403. When the push plate 402 is active, it can drive the return spring 1 404 to be compressed, and use the push rod 403 to push the locking block 11, and the locking block 11 compresses the return spring 2 9, thereby pushing the locking block 11 out of the locking groove 203 and allowing the other end of the locking block 11 to further enter the telescopic cavity 8. At this time, the staff can rotate the rotating column 3, thereby using the rotation of the rotating column 3 to drive the two locking blocks 11 to rotate. When the rotating column 3 rotates 180 degrees, the two locking blocks 11 are exchanged in position, and re-enter the locking groove 203 through the return of the return spring 2 9, and the rotating column 3 is locked again;

[0041] When the rotating column 3 rotates 180 degrees, it can synchronously drive the fixed plate 5 to rotate 180 degrees, thereby driving the two pressing heads 6 at the bottom of the fixed plate 5 to rotate 180 degrees, thereby realizing the position exchange of the two pressing heads 6, that is, the pressing blocks 7 of different widths at the bottom of the two pressing heads 6 are exchanged.
