Description

Technical Field

[0001] The utility model relates to the technical field of LED display screen manufacturing, in particular to an LED display screen manufacturing adjustment mechanism. Background Art

[0002] LED screen is a new type of imaging electronic device made of light-emitting diodes arranged in sequence. Due to its high brightness, wide viewing angle, long life and other characteristics, it is widely used in outdoor advertising screens and other products. The use of LED light sources for lighting will first replace power-consuming incandescent lamps, and then gradually enter the entire lighting market, which will save a lot of electricity. Recently, white LEDs have reached a single power consumption of more than 1 watt and a light output of 25 lumens, which also increases its practicality.

[0003] In the process of making LED display screens, an adjustment mechanism is needed. After searching, the Chinese patent CN216634087U in the prior art discloses an LED display screen production adjustment mechanism, which specifically relates to the field of LED display screen production and processing technology. The existing clamping mechanism is too simple and cannot be adjusted and fixed according to the actual size of the LED display screen when used. It is of low practicality. Moreover, after the LED display screen is clamped, it cannot be rotated and adjusted, which is inconvenient for operators to operate. It includes a processing table, a clamping mechanism is provided on the processing table, and a rotating mechanism is provided on the side of the processing table away from the clamping mechanism; the clamping mechanism includes a placing table, the placing table is rotatably installed on the processing table, and the middle of the placing table is a hollow structure, a servo motor is fixedly installed on the inner side wall of the placing table, a driving gear is fixedly installed on the output end of the servo motor, and a first tooth plate is slidably installed on the inner side wall of the placing table located on the servo motor. The utility model can clamp the LED display screen through the clamping mechanism, and can meet the requirements of clamping and fixing LED display screens of different sizes.

[0004] However, during the use of the utility model, the staff can only process the top of the LED display screen. When the bottom needs to be processed, the LED display screen needs to be removed and reinstalled. This operation increases the workload. At the same time, since the LED display screen is relatively fragile, it may cause damage to the LED display screen and cannot meet production needs. Therefore, an LED display screen production adjustment mechanism is proposed to solve the above-mentioned problems. Utility Model Content

[0009] Furthermore, a rotating plate extending to one side of the support plate is fixedly connected to one side of the mounting frame away from the transmission gear, and a limiting block extending to the inside of the support plate is fixedly connected to one side of the rotating plate.

[0010] Furthermore, the number of the first hinges and the number of the second hinges are both two, the two first hinges and the two second hinges are symmetrically distributed on the front and back sides of the connecting plate, and the first hinge rod is rotatably connected to the second hinge rod.

[0011] Furthermore, a fixing plate is fixedly connected to a side of the installation frame away from the electric push rod, and the movable clamping plate and the fixing plate are the same in shape and size.

[0015] Compared with the prior art, the utility model provides an LED display screen production adjustment mechanism, which has the following beneficial effects:

[0016] 1.

There is no need for the staff to remove the LED display screen and flip it, which makes it easy to flip the LED display screen and improves the processing efficiency.

[0017] 2.

At this time, the mobile clamping plate can be displaced, thereby facilitating the clamping and fixing of the LED display screen, solving the problem that the staff can only process the top of the LED display screen, and when the bottom needs to be processed, the LED display screen needs to be removed and reinstalled. This operation increases the workload. At the same time, since the LED display screen is relatively fragile, it may cause the LED display screen to be damaged and cannot meet the production needs.
