Description

Technical Field

[0001] The utility model provides an LED flexible module pressing fixture, belonging to the technical field of LED display screens. Background Art

[0002] During the production of LED flexible modules, existing pressing jigs rely on a single solenoid valve controlling a cylinder to perform the pressing operation. This manual operation requires pushing and pulling the solenoid valve's rocker back and forth to complete the pressing action, which is cumbersome and increases labor intensity. Furthermore, the frequent vertical movement of the existing pressing jig during operation can easily loosen the cover screws, causing the cover to fall off. Consequently, existing flexible module pressing jigs are cumbersome to operate and pose safety risks. Utility Model Content

[0003] In order to solve the technical problems of complicated operation and poor operating stability of LED flexible module pressing jigs, the utility model proposes an LED flexible module pressing jig that is simple to operate and can operate safely and stably. The purpose is to make the LED flexible module pressing jig simple to operate and can operate safely and stably by improving the hardware structure of the LED flexible module pressing jig or improving the combined connection of hardware modules and / or circuits.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a LED flexible module pressing fixture, comprising a base, a pressing plate and a cover plate, wherein the base, the pressing plate and the cover plate are sequentially arranged on a fixed column, the base is located below the pressing plate, and the pressing plate can slide along the fixed column;

The intermediate relay is also electrically connected to a solenoid valve and a power module. The solenoid valve is electrically connected to the time relay, and the solenoid valve is connected to the cylinder.

[0009] Furthermore, the control box is a box structure, the intermediate relay and the solenoid valve are arranged in the control box, and the time relay is embedded in the control box.

[0010] Furthermore, the upper surface of the limiting groove and the lower surface of the pressing plate are parallel to each other.

[0011] Furthermore, the lower surface of the limiting groove is arranged on the upper surface of the base plate; and the limiting groove is detachable.

[0012] Furthermore, the base, the pressing plate and the cover plate are all square structures.

[0013] Furthermore, the model of the control switch is LADEVR.

[0018] The beneficial effects of the present invention compared to the prior art are as follows:

[0019] 1. The utility model controls the intermediate relay and the time relay through the control switch, sets the action time of the time relay, and after the preset time is reached, the pressing plate automatically lifts and presses according to the preset lifting and pressing time, realizing the timing control of the cylinder action, eliminating the need for the operator to repeat the operation, greatly reducing the operator's labor intensity and improving work efficiency and production efficiency;

[0020] 2. The utility model controls the action of the cylinder through the intermediate relay and the time relay. The cylinder drives the pressure plate to move slowly. Compared with the existing pressing fixture, the pressing and lifting process does not cause the cylinder to move violently repeatedly, thereby causing the screws on the cover to loosen and fall off.

[0025] In the present invention, unless otherwise specified, directional words such as "up, down, top, bottom" are usually used with reference to the directions shown in the drawings, or with reference to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0026] like Figures 1 to 2 As shown, the present invention provides a flexible LED module pressing fixture comprising a wooden square base 1, a pressing plate 2, and a cover plate 3. The base 1 and cover plate 3 are fixedly connected to smooth metal fixing posts 6. The four corners of the pressing plate 2, located between the base 1 and the cover plate 3, are slidably connected to the metal fixing posts. The base 1 is located below the pressing plate 2, and the pressing plate 2 can slide up and down along the fixing posts 6 between the base 1 and the cover plate 3. The pressing plate 2 has a uniform density and a symmetrical shape. The number of fixing posts 6 can be set according to the specific situation to ensure that the pressing plate 2 is evenly stressed on the flexible LED module and the flexible bottom shell to be pressed. This embodiment uses four fixing posts.

[0027] A limiting groove 4 is provided on the base 1. Its lower surface is located on the upper surface of the substrate. The upper surface of the limiting groove 4 is parallel to the lower surface of the pressure plate 2. The structure of the limiting groove 4 is compatible with the device to be pressed, ensuring that the pressure plate 2 applies uniform force to the LED unit board and plastic bottom shell. The limiting groove 4 is located within the area enclosed by the multiple fixing posts 6, and its edge is smaller than the edge of the substrate.

[0028] A cylinder 5 is provided at the center of the cover plate 3. The cylinder 5 is provided with a pressure head fixedly connected to the geometric center of the pressure plate 2. The cylinder 5 is also provided with an air pipe 7, which is connected to a control box 8 via the air pipe 7. The control box 8 is a box-shaped structure and is provided with a control switch 9. The control switch 9 is electrically connected to an intermediate relay and a time relay 10. The intermediate relay is electrically connected to a solenoid valve and a power module. The control box is provided with a control switch 9. The control switch 9 is electrically connected to an intermediate relay and a time relay 10. The intermediate relay is also electrically connected to a solenoid valve and a power module. The solenoid valve is electrically connected to the time relay, which is connected to the cylinder 5. The intermediate relay and the solenoid valve are provided in the control box 8, and the time relay 10 is embedded in the control box 8, ensuring neat wiring and convenient operation and control.

[0029] The model of the control switch 9 is LADEVR, the model of the solenoid valve is 4V210-08, the model of the cylinder 5 is SCJ80×150-50, the model of the time relay 10 is DH48S-2Z, and the model of the intermediate relay is HH54PL-MY4N.

[0030] After the utility model is powered on and ventilated, the LED flexible module is placed in the limit groove 4, and then the control switch 9 is pressed, the intermediate relay and the time relay 10 are activated, and the feedback signal is sent to the solenoid valve, which controls the air supply and air cut-off of the cylinder 5, thereby controlling the action of the pressing plate 2, realizing the compaction, holding and lifting of the pressing plate 2, so that the LED flexible module and the flexible bottom shell are evenly bonded. In addition, the reasonable arrangement of the fixing column 6, the uniform density of the pressing plate 2, and the fixed connection of the lower pressure head of the cylinder 5 to the center position of the pressing plate 2 can fully improve the pressing effect. After the utility model presses the control switch 9 with one button, the pressing plate 2 automatically lifts and presses after the preset time is reached, without the need for manual repeated operation. Since the cylinder 5 moves slowly during the pressing and lifting process, the phenomenon of the screws of the cover plate 3 loosening and falling off can be effectively avoided, thereby ensuring the safety of operation.
