Abstract
Description
Technical Field
[0001] This utility model belongs to the field of LED display and relates to ink brushing technology, specifically to an ink brushing device for an LED light-emitting panel. Background Technology
[0002] LED light-emitting panels are an important component of LED display devices. To achieve the required lighting effect, the front surface of the LED light-emitting panel needs to be inked. The existing method is to move the screen printing fixture under the screen frame via a conveyor belt, and then the screen frame performs inking on the LED light-emitting panel on the screen printing fixture. This method has some problems in actual operation. Specifically, it is difficult to accurately position the screen printing fixture, and the optimal inking position varies for LED light-emitting panels of different shapes and sizes. This method cannot achieve the optimal inking position for different LED light-emitting panels, which leads to the final inking effect not reaching the ideal state. Summary of the Invention
[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, an ink brushing device for LED light-emitting panels is provided, which can accurately position the screen printing fixture and make targeted fine adjustments to the position of the screen frame according to the actual shape and size of the LED light-emitting panel, thereby ensuring that the LED light-emitting panel and the screen frame reach the optimal ink brushing position and effectively improving the ink brushing effect.
[0004] Technical Solution: To achieve the above objectives, this utility model provides an ink-brushing device for an LED light-emitting panel, including a turntable and an ink-brushing mechanism. Four screen printing fixtures are radially symmetrically arranged on the turntable. The ink-brushing mechanism includes a left-right adjustment bracket, a front-back adjustment bracket, and a screen frame. At least one left-right adjustment screw is provided on the left-right adjustment bracket. The front-back adjustment bracket includes two adjustment parts and a connecting part. The connecting part is fitted onto the left-right adjustment screw. The adjustment parts are provided with a front-back adjustment screw and a fixing bracket fitted onto the front-back adjustment screw. Several longitudinal locking bolts are provided on the fixing bracket. The screen frame is mounted on two fixing brackets. The longitudinal locking bolts are used to lock and fix the screen frame. Left-right fine-tuning rotating nuts and up-down fine-tuning rotating nuts are respectively provided on the left-right adjustment screw and the front-back adjustment screw.
[0005] Furthermore, the adjustment part is provided with transverse locking bolts. The two transverse locking bolts can clamp the mesh frame from left to right, thereby ensuring the fixation effect of the mesh frame.
[0006] Furthermore, the two ends of the left and right adjusting screw are provided with first bearings, and the left and right fine-tuning rotating nuts are disposed on the first bearings.
[0007] Furthermore, the two ends of the front and rear adjusting screw are provided with second bearings, and the front and rear fine-tuning rotating nut is disposed on the second bearings.
[0008] Furthermore, the screen printing fixture is provided with a panel groove for placing LED light-emitting panels, and different LED light-emitting panels correspond to different panel grooves.
[0009] Beneficial effects: Compared with the prior art, this utility model adopts a turntable conveying method instead of a linear conveying method, and designs left and right adjustment brackets and front and back adjustment brackets to realize the left and right fine adjustment and front and back fine adjustment of the screen frame respectively. It can accurately position the screen printing fixture, and can make targeted fine adjustments to the position of the screen frame according to the actual shape and size of the LED light-emitting panel, thereby ensuring that the LED light-emitting panel and the screen frame reach the optimal ink-brushing position and effectively improve the ink-brushing effect.

[0014] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only for illustrating the present invention and are not intended to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.
[0015] like Figures 1-4As shown, this utility model provides an ink brushing device for an LED light-emitting panel, including a turntable 1 and an ink brushing mechanism. A rotating shaft 2 is centrally located on the turntable 1. Four screen printing fixtures 3 are radially symmetrically arranged on the turntable 1, with an angle of 90 degrees between them. Each screen printing fixture 3 has a panel groove 4. The ink brushing mechanism includes a left-right adjustment bracket 5, a front-back adjustment bracket 6, a screen frame 11, and a support bracket 100. The left-right adjustment bracket 5 is fixed to the support bracket 100. Two left-right adjustment screws 13 are provided on the left-right adjustment bracket 5, and first bearings 15 are provided at both ends of the left-right adjustment screws 13. The fine-tuning rotating nut 9 is set on the first bearing 15 at one end. The front and rear adjustment bracket 6 includes two adjustment parts 61 and a connecting part 14. The connecting part 14 is fitted on two left and right adjustment screws 13. The adjustment part 61 is provided with a front and rear adjustment screw 16 and a fixing bracket 7 fitted on the front and rear adjustment screw 16. The fixing bracket 7 is provided with three longitudinal locking bolts 12. The side of the adjustment part 61 is provided with a transverse locking bolt 10. The two ends of the front and rear adjustment screw 16 are provided with second bearings 17. The front and rear fine-tuning rotating nut 8 is set on the second bearing 17. The mesh frame 11 is installed on the two fixing brackets 7.
[0016] In this embodiment, the above-mentioned ink-brushing device is applied in a practical way. The specific operation process is as follows: First, select a screen printing fixture 3 with matching panel slots 4 according to the shape and size of the LED light-emitting panel. Install four screen printing fixtures 3 on the turntable 1 respectively, and place the four LED light-emitting panels in the four panel slots 4 respectively. Start the motor and rotate one of the screen printing fixtures 3 to the designated position below the screen frame 11 through the rotating shaft 2. Then, according to the specifications of this LED light-emitting panel, the operator first adjusts the front and back position of the screen frame 11 by rotating the two front and back fine-tuning rotating nuts 8. After the fine-tuning is completed, tighten all the longitudinal locking bolts 12 and the two transverse locking bolts 10 respectively to effectively fix the screen frame 11. Fix the frame 11, and then move the front and rear adjustment bracket 6 left and right by rotating the two left and right fine adjustment nuts 9. That is, make fine adjustments to the left and right position of the frame 11. After the fine adjustment, the frame 11 is in the optimal ink brushing position. The operator controls the ink brushing device to brush the LED light-emitting panel. After the ink brushing is completed, the turntable 1 rotates 90 degrees to move the second LED light-emitting panel to the ink brushing station. At this time, the frame 11 is kept in the optimal ink brushing position to perform ink brushing. During the ink brushing process, the operator can take out the ink-brushed LED light-emitting panel in time and then install the LED light-emitting panel to be brushed. By doing this, the continuous ink brushing of the LED light-emitting panel can be achieved.
[0017] During the above ink application process, the positional accuracy of the screen printing fixture 3 and the optimal ink application position of the frame 11 can be guaranteed, ensuring that the ideal ink application effect can be achieved for LED light-emitting panels of different shapes and sizes, and the ink application effect is guaranteed.
