The production of traditional ink-brushed LED brackets is to ship the products after the processes of hardware strip, injection molding, bending, and ink brushing into the encapsulation link. Because the appearance of the bracket is darker after ink brushing, the overall effect is very good-looking after making the finished product and pasting it on the screen, and the contrast is higher, that is, the gray level is higher, which promotes the downstream screen factories to vigorously promote such a highly competitive technology, and this technology is also deeply loved by end-use customers. The existing ink-brushing fixtures for LED brackets mainly use flat cross-shaped frames. By pressing down the brackets and placing the brackets upside down, the method of pad printing is used to achieve single-sided printing of the brackets. The above common types of ink-brushing fixtures for LED brackets have the following problems in actual applications:

Detailed implementation manners
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0022] Please refer to Figures 1-5 , the present utility model provides a fixture for improving the ink brushing quality of LED brackets, including a base 1, a vertical frame 2 and a support 12 fixedly arranged on the base 1. A ink brushing guide table 4 is fixedly arranged in the middle of the base 1, and a printing fixture 3 for printing LED brackets is fixedly installed in the middle of the ink brushing guide table 4. An electric control hydraulic cylinder 7 is fixedly installed in the middle of the top of the vertical frame 2, and a support placement mechanism 6 for pressing down the inverted LED brackets is fixedly installed at the telescopic end of the electric control hydraulic cylinder 7. A negative suction mechanism is fixedly installed on one side of the top of the vertical frame 2, a support loader 11 is fixedly installed at the top of the support 12, and an ink brushing machine 13 is fixedly installed at the bottom of the support 12.
[0023] Refer to Figure 1 , Figure 2 and Figure 3 , further, the printing fixture 3 includes a lower flat plate 31 and an upper flat plate 32 matching with the lower flat plate 31. A plurality of cross slots 33 are opened on the surface of the upper flat plate 32. A plurality of pad printing components are fixedly installed on the surface of the lower flat plate 31. Micro cylinders 35 are fixedly installed at the four corners of the bottom end of the lower flat plate 31. The pad printing component includes a cross ink transfer frame 34. A plurality of ink retention grooves 36 are opened at the top of the cross ink transfer frame 34. The cross ink transfer frame 34 and the cross slots 33 are arranged in one-to-one correspondence;
[0024] In use, in the initial state, the cross ink transfer rack 34 is flush with the cross groove 33. The ink brushing mechanism 13 pushes the ink cartridge along the ink brushing guide table 4, so that ink is retained on the cross ink transfer rack 34. The surface of the cross ink transfer rack 34 is provided with a plurality of square ink retaining grooves 36, which can carry more ink during printing transfer, making the ink thickness on the rack higher, the color darker, and more textured. When brushing ink, the micro cylinder 35 will extend, pushing the lower flat plate 31 to move upward as a whole, so that the cross ink transfer rack 34 moves upward and protrudes from the cross groove 33. The retained ink is transferred to the LED bracket by relying on the protruding cross ink transfer rack 34.
[0025] Refer to Figure 1 and Figure 4 Furthermore, the bracket placing mechanism 6 includes an imprinting plate 61 and a negative suction cavity 63 opened inside the imprinting plate 61. A negative suction interface 65 communicating with the inside of the negative suction cavity 63 is fixedly installed at the top end of the imprinting plate 61. A plurality of negative suction holes 64 are opened in the middle of the bottom end of the imprinting plate 61. The negative suction mechanism includes a vacuum negative suction pump 9. The air inlet of the vacuum negative suction pump 9 is fixedly communicated with a high-pressure hose 10. The bottom end of the high-pressure hose 10 is fixedly installed on the negative suction interface 65. The bracket loader 11 is arranged opposite to the imprinting plate 61.
[0026] In use, when the bracket loader 11 pushes the LED bracket to be printed to the bottom of the imprinting plate 61, the vacuum negative suction pump 9 generates negative pressure in the negative suction cavity 63 through the high-pressure hose 10, so as to adsorb the pushed LED bracket through the negative suction holes 64. Subsequently, the electric control hydraulic cylinder 7 extends, pushing the imprinting plate 61 to move downward, pressing the placed LED bracket on the cross ink transfer rack 34, and realizing the transfer of ink. After the transfer is completed, the vacuum negative suction pump 9 stops working, and the bracket remains on the printing fixture 3, and at the same time, the electric control hydraulic cylinder 7 resets.
[0027] Refer to Figure 1 Furthermore, guide posts 8 are fixedly arranged at the four corners of the top end of the imprinting plate 61. The guide posts 8 are slidably arranged on the vertical frame 2. Positioning grooves 62 are opened at the four corners of the bottom end of the imprinting plate 61. Four positioning posts 5 are fixedly arranged at the edge of the ink brushing guide table 4. The positioning posts 5 and the positioning grooves 62 are arranged in one-to-one correspondence. Both the lower flat plate 31 and the upper flat plate 32 are made of stainless steel.
[0028] In use, during the process of the imprinting plate 61 moving downward for printing, the guide posts 8 will slide on the vertical frame 2 to keep the imprinting plate 61 from shifting, ensuring the accuracy of imprinting.
[0029] When the embodiment of the present application is in use: The LED brackets to be printed are stacked on the bracket loading machine 11, and the bracket loading machine 11 directly pushes the LEDs at the bottom into the bottom of the bracket placing mechanism 6. The vacuum negative suction pump 9 will generate negative pressure in the negative suction cavity 63 through the high-pressure hose 10, so as to adsorb the pushed LED brackets through the negative suction holes 64. In the initial state, the cross ink transfer frame 34 is flush with the cross groove 33. The ink brushing mechanism 13 pushes the ink cartridge to move along the ink brushing guide table 4, so as to retain the ink on the cross ink transfer frame 34. After ink brushing, the micro cylinder 35 will extend, pushing the lower flat plate 31 to move upward as a whole, so that the cross ink transfer frame 34 moves upward and protrudes from the cross groove 33. Subsequently, the electric control hydraulic cylinder 7 pushes the bracket placing mechanism 6 to move downward, places the LED brackets at the bottom on the cross ink transfer frame 34, and transfers the retained ink to one side of the LED brackets by means of stamping. The printing efficiency is high and the printing quality is higher. Figure 5 The upper part is the rendering of the traditional transfer fixture after printing, and the lower part is the printing rendering of the improved transfer fixture. After improvement, the color is darker, more textured, the contrast is higher, and the appearance of the finished product is more likely to win customer satisfaction.
