TECHNICAL FIELD

[0001] The present application belongs to the technical field of filter production, and specifically relates to a filter screen printing machine. BACKGROUND

[0002] The filter screen printing machine is a special equipment for screen printing on the surface of the filter. The general working principle of the filter screen printing machine is as follows: preparation work: first, the filter substrate and the screen printing plate need to be prepared; the filter substrate is usually a transparent plate or film, and the screen printing plate is made of a silk screen, and the printing pattern on the silk screen corresponds to the required light filtering characteristics; ink preparation: according to the required light filtering characteristics, select the appropriate ink or pigment; the ink can have the spectral characteristics of absorbing, transmitting or reflecting specific wavelengths of light; adjust the machine parameters: according to the size of the filter, the pattern to be printed and the characteristics of the ink, adjust the parameters of the screen printing machine; this includes setting the silk screen tension, the speed of the propeller and the pressure, the supply speed of the ink on the silk screen, etc.; install the screen printing plate on the machine: install the screen printing plate prepared in advance on the special clamp of the screen printing machine, and ensure that it is aligned with the filter substrate; ink coating: coat the ink or pigment in the ink tank above the silk screen; the ink is scraped along the silk screen by a scraper or printing scraper, and is transmitted to the surface of the filter through the fine holes of the silk screen; printing process: the filter substrate is placed on the workbench of the screen printing machine, the screen printing machine presses the silk screen and transfers the ink to the surface of the filter; the ink is transmitted to the filter substrate through the holes on the silk screen, and the required pattern or texture is formed; baking and curing: after the ink is transferred to the filter, baking and curing are performed; this can be done by heat treatment, ultraviolet radiation or chemical reaction, etc. to make the ink or pigment form a stable pattern on the filter; completion and quality inspection: after the screen printing is completed, the filter needs to be inspected to ensure the integrity of the pattern and the light filtering characteristics meet the requirements; quality inspection can include optical measurement, visual inspection and spectral analysis, etc. To improve the module stray light and improve the imaging effect of the module, double-sided screen printing is performed under the condition of ensuring the product concentricity.

[0003] However, in the prior art, the process of double-sided screen printing is generally AR face screen printing + baking + IR face screen printing + baking, and in this process, manual face changing of the filter and separate baking are required, which greatly reduces the work efficiency; the general screen printing machine can only process one filter, which is low in efficiency; there is a large difference in the concentricity of the front and back screen printing patterns during the screen printing process, which affects the product quality.

[0004] Therefore, we propose a filter screen printing machine to solve the problems in the prior art, improve the work efficiency, enable baking and screen printing on the same machine, enable automatic face changing of the filter for screen printing, realize the effect of efficient double-sided screen printing, effectively ensure the screen printing concentricity through the clamp or other design, and enable multiple filters to be screen printed at the same time, thereby improving the screen printing efficiency.

The specific embodiments described herein are merely used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0090] This invention provides a screen printing machine for optical filters, exemplarily, such as... Figure 1 As shown, it includes a machine body 1, a lifting device 2, a printing device 3, a screen printing device 4, and a filter body 5.

[0091] The printing device 3 is installed on the top of the machine body 1; the lifting device 2 is installed on the top of the machine body 1, and the screen printing device 4 moves up and down through the lifting device 2; the screen printing device 4 is located directly above the printing device 3.

[0092] Specifically, the filter body 5 is fixed to the printing equipment 3 by the clamp 360, and the screen printing equipment 4 is moved to the printing equipment 3 by the lifting equipment 2 to screen print the filter body 5.

[0093] like Figure 1 and Figure 6 As shown, in this embodiment, the printing device 3 includes: a printing frame 310, a printing table 320, a card slot 330, a driving device 340, a curing device 350, and a clamp 360; specifically as follows:

[0094] The printing frame 310 is installed on the top of the machine body 1. The inner cavity of the printing frame 310 is movably connected to the flip-out printing table 320. The surface of the printing table 320 is provided with a slot 330 that is adapted to the filter body 5.

[0095] Specifically, with the setting of the flip-out printing table 320, the user can clamp and fix the filter body 5 to be screen printed in the inner cavity of the slot 330 by the clamp 360, and then screen printing can be performed. After screen printing on one side of the filter body 5 is completed, the printing table 320 can be flipped to screen print on the other side of the filter body 5.

[0096] like Figure 7As shown, when the driving device 340 fails, in order to facilitate the turning of the printing platform 320, the embodiment also discloses a turner 370, which is manually operated, and the turner 370 comprises a turning gear 371 fixedly installed at one end of the rotating shaft 341, a shell 372 installed on one side of the printing frame 310 and located at the corresponding position of the turning gear 371, two groups of sliding blocks 373 slidably connected in the inner cavity of the shell 372, a toothed plate 374 fixedly connected to the inner side of the two groups of sliding blocks 373, the bottom of the turning gear 371 engaged with the top of the toothed plate 374, a rubber spring 375 fixedly connected to the side of the sliding block 373 away from the toothed plate 374, one end of the rubber spring 375 away from the sliding block 373 fixedly connected to the inner wall of the shell 372, and a pull rod 376 provided at one end of the shell 372, one end of the pull rod 376 penetrating through the shell 372 and fixedly connected to the surface of one of the two groups of sliding blocks 373.

[0097] Specifically, in the embodiment, the printing platform 320 is initially inclined, and after the filter body 5 is fixed on the printing platform 320 by the clamp 360, the user can directly press the filter body 5 on the printing platform 320 by the silk-screen printing device 4 to perform silk-screen printing.

[0098] During the pressing process, the printing platform 320 is flattened to facilitate silk-screen printing on the filter body 5, and during the process of rotating the printing platform 320 to the horizontal state, the toothed plate 374 is driven to move by the turning gear 371, thereby driving the two groups of sliding blocks 373 to move in the inner cavity of the shell 372, at this time, one group of rubber springs 375 is in a stretched state, and the other group of rubber springs 375 is in a compressed state.

[0099] After the silk-screen printing is completed, the silk-screen printing device 4 is raised, at this time, under the action of the two groups of rubber springs 375, the printing platform 320 returns to the initial inclined state, at this time, the user can push the pull rod 376 to make the printing platform 320 in a reverse inclined state, at this time, the user can repeat the above silk-screen printing steps to perform silk-screen printing on the other side of the filter body 5.

[0100] In addition, the curing device 350 for curing the silk-screen printed pattern on the surface of the filter body 5 is installed in the inner cavity of the printing frame 310, and the clamp 360 for clamping and fixing the filter body 5 in the inner cavity of the clamping groove 330 is also included.

[0101] As shown in the drawings, Figure 6 The clamp 360 described above in the embodiment comprises a mounting groove 361, a clamping plate 362, and a compression spring 363, and the specific implementation is as follows:

[0103] When the filter body 5 is clamped and positioned, the user can push the filter body 5 into the inner cavity of the clamping groove 330, and the movement of the filter body 5 will push the clamping plate 362 to move, and then the clamping plate 362 will press the compression spring 363.

[0104] When the filter body 5 is completely clamped into the inner cavity of the clamping groove 330, the reaction force generated by the compression of the compression spring 363 will tightly fix the filter body 5 in the inner cavity of the clamping groove 330.

[0105] In some other embodiments, a driving device 340 is further arranged on the top of the body 1 to drive the printing platform 320 to flip, under normal circumstances, the driving device 340 can drive the printing platform 320 to flip, as shown in the figure, the driving device 340 comprises a rotating shaft 341, a driving motor 342, a driving gear 343, a driven gear 344, a belt 345 and a connecting shaft 347, and the specific structure is as follows: Figure 7

[0106] The rotating shaft 341 is arranged in the interior of the printing platform 320, both ends of the rotating shaft 341 are rotatably connected to the inner wall of the printing frame 310, and one end of the rotating shaft 341 penetrates through the printing frame 310 and extends to the outside of the printing frame 310;

[0108] Specifically, after the silk printing on one side of the filter body 5 is completed, the user can turn on the driving motor 342 through the external controller, the output shaft of the driving motor 342 will drive the driving gear 343 to rotate, and then the driving gear 343 will drive the driven gear 344 to rotate through the belt 345, the rotation of the driven gear 344 will drive the printing platform 320 to flip through the connecting shaft 347, the flipping gear 371 and the rotating shaft 341, so as to flip the filter body 5, so as to realize the purpose of double-sided silk printing.

[0109] ​Through the cooperation of the driving device 340 and the turnover device 370, the normal situation is controlled by the driving device 340 to control the turnover, and then the fine adjustment turnover device 370 is controlled to realize the parallel state of the printing platform 320 and the ink passing through the silk screen 467, thereby controlling the silk printing accuracy, and when the silk printing is completed, the turnover device 370 automatically returns to the initial state, and when an emergency state such as power failure or motor failure occurs, the turnover silk printing can be manually performed only through the turnover device 370, and high-efficiency double-sided silk printing is realized under the cooperation of the driving device 340 and the turnover device 370.

[0110] In addition, the mounting frame 346 mounted on the top of the machine body 1 is also included, and the top of the mounting frame 346 is fixedly connected with the surface of the driving motor 342, and through the setting of the mounting frame 346, the use position of the driving motor 342 can be mounted and fixed, and it is mounted and fixed on the top of the machine body 1.

[0111] As shown in Figure 5 The curing device 350 in the embodiment includes a mounting frame 351, ultraviolet lamp tubes 352, and heat transfer pipes 353, and the specific implementation is as follows:

[0112] The mounting frame 351 is slidingly connected to the inner cavity of the printing frame 310, and the bottom of the mounting frame 351 is slidingly connected to the top of the machine body 1, the ultraviolet lamp tubes 352 are provided in multiple groups, and the multiple groups of ultraviolet lamp tubes 352 are equidistantly mounted in the inner cavity of the mounting frame 351, and the heat transfer pipes 353 are communicated to one side of the printing frame 310.

[0113] Specifically, through the setting of the curing device 350, during the silk printing process, the user can turn on the ultraviolet lamp tubes 352 to use the curing effect of ultraviolet rays to cure the ink on the surface of the filter body 5, and at the same time, the user can connect an external heating device not shown in the figure through the heat transfer pipes 353 to inject hot air into the printing frame 310 to double-cure the ink on the surface of the filter body 5, thereby improving the curing efficiency and curing effect.

[0114] In addition, the arc-shaped plates 355 fixedly connected to the top of the mounting frame 351 are also included, and the surface of the printing platform 320 is slidingly connected with the arc-shaped part of the arc-shaped plate 355, and the sliding rods 356 are fixedly connected to the front and rear sides of the mounting frame 351, and the inner wall of the printing frame 310 is provided with the sliding grooves 357 matched with the sliding rods 356, and the surface of the sliding rods 356 is slidingly connected with the inner wall of the sliding grooves 357.

[0115] Specifically, the mounting frame 351 can adjust its use height with the rotation of the printing table 320. When the printing table 320 rotates, its surface will push the mounting frame 351 to move through the arc-shaped plate 355. The movement of the mounting frame 351 will extrude the return spring 354. When the printing table 320 is in a horizontal state for silk printing, the reaction force generated by the contraction of the return spring 354 will push the mounting frame 351 upwards, so that the ultraviolet lamp tube 352 is close to the filter body 5, so as to solidify the ink on the surface. Through the cooperation of the sliding rod 356 and the sliding groove 357, the stability of the movement of the mounting frame 351 can be improved.

[0116] Through the rotation cooperation of the printing table 320 and the arc-shaped plate 355, the printing table 320 generates an extrusion effect on the arc-shaped plate 355. When the printing table 320 is in a vertical state, on the one hand, the arc-shaped plate 355 fixes the printing table 320, and on the other hand, the compression of the return spring 354 makes the mounting frame 351 descend, so as to increase the internal space and facilitate the taking and placing of the finished product after silk printing. When the printing table 320 is in a horizontal state, the return spring 354 resets, so that the ultraviolet lamp tube 352 is closer to the filter body 5, so as to solidify the ink on the surface and improve the solidification efficiency.

[0117] As shown in Figure 2 the embodiment, the lifting device 2 described above comprises a fixed seat 210, a fixed shell 220, a driving motor two 230, a driving screw 240, a sliding seat 250 and a connecting block 260. Specifically as follows:
