Description

Technical Field

[0001] This utility model belongs to the technical field of display equipment, and in particular relates to a liquid crystal display screen patch pretreatment device. Background Technology

[0002] LCD panel mounting is essentially a core process that uses surface mount technology (SMT) to precisely mount micro-electronic components (such as driver ICs, resistors, capacitors, connectors, etc.) onto the LCD's driver PCB or glass substrate.

[0003] Before the LCD screen is mounted, it needs to undergo pre-treatment such as wiping and applying adhesive. To fix the position of the main body of the display screen during the pre-treatment process, an LCD screen mounting pre-treatment device was designed. This device uses a combination of a double-layer carrier panel and multiple limiting components to clamp and fix the LCD screen to the top of the double-layer carrier panel. This prevents the LCD screen from being scratched due to movement during the wiping and other pre-treatment processes. Utility Model Content

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A liquid crystal display panel patch pretreatment device includes a vertical groove opened on the top of a double-layer carrier panel; a horizontal groove is opened on the top of the double-layer carrier panel; parallel double grooves are opened on the front side and the left side of the top of the double-layer carrier panel; a slotted movable strip and a slotted movable block are slidably connected to the top of the double-layer carrier panel; threaded tubes are welded to the inner cavities of the slotted movable strip and the slotted movable block; a threaded column is threadedly connected to the inner cavity of the threaded tube; a base is welded to the bottom end of the threaded column; and a rubber wheel is rotatably connected to the surface of the base.

[0006] Preferably, the slotted movable strip is located above the parallel double slots, and the slotted movable block is located above the vertical slot and the horizontal slot.

[0007] Preferably, the rubber wheel is slidably connected to the inner cavity of the vertical groove, the horizontal groove, and the parallel double groove.

[0008] Preferably, an octagonal head is welded to the top of the threaded column, and a round rod is rotatably connected to the inner cavity of both the slotted movable strip and the slotted movable block.

[0009] Preferably, two rollers are rotatably connected to the surface of the round rod, and a limiting round head is welded to the top of the round rod.

[0010] Preferably, a liquid crystal display screen is placed on top of the double-layer carrier panel, and the slotted movable strip and the slotted movable block are both attached to the surface of the liquid crystal display screen.

[0011] The beneficial effects of this utility model are: 1. This utility model uses the screw thread to drive the rubber wheel to slide downwards until the bottom of the rubber wheel contacts the inner wall of the vertical groove, the horizontal groove and the parallel double groove, thereby fixing the position of the slotted movable block and the slotted movable strip, and thus clamping and fixing the LCD screen to the top of the double-layer carrier panel. This achieves the purpose of preventing the LCD screen from being scratched due to the movement of the LCD screen during the pre-processing such as wiping. 2. By using a round rod and rollers in combination, this utility model enables the slotted movable strip and slotted movable block to connect with the inner cavity of the vertical groove, horizontal groove and parallel double groove during the sliding process, and at the same time makes the slotted movable strip and slotted movable block move more smoothly.

[0014] In the following description, embodiments of the liquid crystal display panel patch preprocessing apparatus of the present invention will be described with reference to the accompanying drawings. Example

[0015] Figure 1-4This invention illustrates a liquid crystal display panel patch pretreatment device according to an embodiment of the present invention. The device includes a vertical groove 2 formed on the top of a double-layer carrier panel 1; a horizontal groove 3 formed on the top of the double-layer carrier panel 1; parallel double grooves 4 formed on the front and left sides of the top of the double-layer carrier panel 1; a slotted movable strip 5 and a slotted movable block 6 slidably connected to the top of the double-layer carrier panel 1; threaded tubes 7 welded to the inner cavities of both the slotted movable strip 5 and the slotted movable block 6; threaded posts 8 threadedly connected to the inner cavities of the threaded tubes 7; a base support 9 welded to the bottom end of the threaded posts 8; and a rubber wheel 10 rotatably connected to the surface of the base support 9. The slotted movable strip 5 is located above the parallel double grooves 4, and the slotted movable block 6 is located above the vertical groove 2 and the horizontal groove 3. The rubber wheel 10 is slidably connected to the inner cavities of the vertical groove 2, the horizontal groove 3, and the parallel double groove 4. A liquid crystal display 15 is placed on the top of the double-layer carrier panel 1, and the slotted movable strip 5 and the slotted movable block 6 are both attached to the surface of the liquid crystal display 15. Example

[0016] Figure 1-4 This invention illustrates a liquid crystal display panel patch pre-processing device according to an embodiment of the present invention. It includes a vertical groove 2 formed on the top of a double-layer carrier panel 1; a horizontal groove 3 formed on the top of the double-layer carrier panel 1; parallel double grooves 4 formed on the front side and left side of the top of the double-layer carrier panel 1; a slotted movable strip 5 and a slotted movable block 6 slidably connected to the top of the double-layer carrier panel 1; threaded tubes 7 welded to the inner cavities of both the slotted movable strip 5 and the slotted movable block 6; threaded posts 8 threadedly connected to the inner cavities of the threaded tubes 7; and a base support 9 welded to the bottom end of the threaded posts 8. The surface of the base support 9 rotates... The movable connection is a rubber wheel 10, and the top of the threaded column 8 is welded with an octagonal head 11. The inner cavities of the slotted movable strip 5 and the slotted movable block 6 are rotatably connected to a round rod 12. The surface of the round rod 12 is rotatably connected to two rollers 13. Through the cooperation of the round rod 12 and the rollers 13, the slotted movable strip 5 and the slotted movable block 6 can be connected with the inner cavities of the vertical groove 2, the horizontal groove 3 and the parallel double groove 4 during the sliding process. At the same time, it can make the slotted movable strip 5 and the slotted movable block 6 move more smoothly. The top of the round rod 12 is welded with a limiting round head 14.

[0017] Working Principle: When using this utility model, the user places the LCD screen 15 on top of the double-layer carrier panel 1, and then moves the position of the slotted movable block 6 and slotted movable strip 5. During the movement, the vertical slot 2, horizontal slot 3, and parallel double slot 4 can keep the slotted movable strip 5 and slotted movable block 6 sliding in a straight line. After the slotted movable strip 5 and slotted movable block 6 abut against the periphery of the LCD screen 15, the octagonal head 11 is turned to drive the threaded column 8 to rotate. At this time, the thread causes the threaded column 8 to slide downward and press the rubber wheel 10 to slide downward until the bottom of the rubber wheel 10 contacts the inner wall of the vertical slot 2, horizontal slot 3, and parallel double slot 4. Then the position of the slotted movable block 6 and slotted movable strip 5 is fixed, thereby clamping and fixing the LCD screen 15 to the top of the double-layer carrier panel 1. This prevents the LCD screen 15 from being scratched due to movement during pre-treatment such as wiping.

[0018] In summary, this LCD screen patch pretreatment device, by turning the threaded post 8, drives the rubber wheel 10 to slide downwards until the bottom of the rubber wheel 10 contacts the inner walls of the vertical groove 2, the horizontal groove 3, and the parallel double groove 4, thereby fixing the positions of the grooving movable block 6 and the grooving movable strip 5, and thus clamping and fixing the LCD screen 15 to the top of the double-layer carrier panel 1. This achieves the purpose of preventing scratches on the screen surface caused by the movement of the LCD screen 15 during pretreatment such as wiping.
