TECHNICAL FIELD

[0001] The utility model relates to a positioning device, especially to an auxiliary positioning device for optical film processing, and belongs to the technical field of optical film processing. BACKGROUND

[0002] Optical film is a kind of optical medium material composed of thin layered medium and propagating light beam through interface. The application of optical film started in the 1930s. Today, optical film has been widely used in optical and optoelectronic technology fields to manufacture various optical instruments. Auxiliary positioning devices are needed to position and fix optical films during processing, so as to facilitate subsequent processing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-8This utility model provides an auxiliary positioning device for optical film processing, including a table 1, with boxes 2 on both sides of the top of the table 1. A lead screw 3 is rotatably mounted inside each box 2. Both ends of the lead screw 3 are threadedly connected to sliders 4 via lead screw nuts. By rotating the lead screw 3 with opposite directions at both ends, the two sliders 4 and two supports 5 can be adjusted synchronously in opposite directions, thereby adjusting the corresponding rubber blocks 9. This allows for the pressing, positioning, and fixing of optical films of different sizes. A support 5 is fixedly mounted on one side of each slider 4. A rotating rod 6 is rotatably mounted in the middle of the support 5. A gear 7 is fixedly mounted in the middle of the rotating rod 6. A support plate 8 is fixedly mounted on the surface of the rotating rod 6. A rubber block is fixedly mounted on one side of the bottom of the support plate 8. Block 9 and gear 7 are meshed with a rack plate 10 on one side. By moving the rack plate 10, the gear 7 is rotated and adjusted, which in turn drives the rotating rod 6 and the support plate 8 to rotate and adjust synchronously. This allows the optical film at the table 1 to be pressed, positioned and fixed, which can meet the requirements for pressing, positioning and fixing the optical film during the processing, avoid displacement during the processing, ensure the accuracy of subsequent processing and reduce the scrap rate. Moreover, since springs are not used, the pressing force will not decrease, and frequent inspection and replacement are not required, reducing maintenance costs. The top of the bracket 5 is provided with a moving component 11 for moving the rack plate 10, and a dust suction hood 12 is provided above the table 1. The top of the table 1 is provided with an adjusting component 13 for adjusting the dust suction hood 12.

[0029] The movable component 11 includes a fixed frame 1101, which is fixedly installed on one side of the top of the bracket 5. A threaded rod 1102 is threadedly connected to the middle of the fixed frame 1101. The bottom end of the threaded rod 1102 is rotatably connected to the top of the rack plate 10. A knob 1105 is fixedly installed at the top of the threaded rod 1102. Mounting plates 1103 are fixedly installed on the top of both sides of the rack plate 10. A limiting rod 1104 is fixedly installed at the top of each mounting plate 1103. The top of the limiting rod 1104 passes through the fixed frame 1101 and extends to the top of the fixed frame 1101. Through the movable component 11, the knob 1105 drives the threaded rod 1102 to rotate, so that the threaded rod 1102 rotates in the middle of the fixed frame 1101. Combined with the limiting rod 1104, the rack plate 10 can move in the vertical direction, thereby driving the meshing gear 7 to rotate and adjust.

[0030] The adjustment assembly 13 includes a mounting bracket 1301, which is fixedly mounted at the center of the top of the tabletop 1. An electric telescopic column 1302 is fixedly mounted at the center of the top of the mounting bracket 1301. The telescopic rod of the electric telescopic column 1302 passes through the mounting bracket 1301 and has two support rods 1303. The top of the dust collection hood 12 is fixedly connected to the bottom of the support rods 1303. A vertical plate 1304 is fixedly mounted on one side of the top of the mounting bracket 1301. A branch pipe 1305 is fixedly mounted in the middle of the vertical plate 1304. The bottom of the branch pipe 1305 passes through the mounting bracket 1301 and has a flexible hose 130. 6. The bottom end of the hose 1306 is fixedly connected to the middle of the top of the dust hood 12, and the other end of the branch pipe 1305 is fixedly provided with a flange; through the set adjustment component 13, it is connected and fixed to the relevant dust removal equipment through the flange, so that dust generated during optical film processing can be removed. By controlling the extension and retraction of the electric telescopic column 1302, the two support rods 1303 can be moved in the vertical direction, so that the height of the dust hood 12 can be adjusted, making it more convenient to use; the set hose 1306 makes the movement of the dust hood 12 unrestricted.

[0031] The threads at both ends of the lead screw 3 are turned in opposite directions, which facilitates the synchronous movement of the two sliders 4. A rotating assembly 15 is provided on one side of the box body 2. The rotating assembly 15 includes a horizontal plate 1501, which is fixedly installed on one side of the box body 2. A worm gear 1502 is rotatably provided in the middle of the horizontal plate 1501. One end of the lead screw 3 passes through the box body 2 and is provided with a worm wheel 1503. The worm gear 1502 and the worm wheel 1503 are meshed and connected. A nut 1504 is fixedly provided at the top of the worm gear 1502. Two guide rods 16 are symmetrically slidable between the two sliders 4. Both ends of the guide rods 16 are fixedly connected to the inner wall of the box body 2. Through the rotating assembly 15, the nut 1504 can be used to drive the worm gear 1502 to rotate, which in turn can drive the meshed worm wheel 1503 to rotate, thereby driving the lead screw 3 to rotate in both directions.

[0032] An electric push rod 14 is fixedly installed on one side of the top of the tabletop 1. The telescopic rod of the electric push rod 14 is fixedly connected to one side of one of the boxes 2. The bottom end of the other box 2 is fixedly connected to one side of the top of the tabletop 1. The electric push rod 14 facilitates the movement of one of the boxes 2 on the surface of the tabletop 1, thereby enabling the pressing, positioning, and fixing of optical films of different lengths and sizes, greatly improving flexibility. A base 20 is fixedly installed at the bottom of the tabletop 1. An anti-slip pad is fixedly installed at the bottom of the base 20 to provide support and prevent slippage. A blocking block 19 is fixedly installed in the middle of the top of the tabletop 1 to limit and block the optical film. Guide blocks 17 are fixedly installed on both sides of the bottom of one of the boxes 2. A guide groove 18 is opened on the surface of the tabletop 1 to slide and cooperate with the guide block 17. The guide block 17 and the guide groove 18 ensure that the guide block 17 moves freely and guides the box 2 when it moves.

[0033] In use, firstly, the flange at branch pipe 1305 is connected and fixed to the relevant dust removal equipment to facilitate the removal of waste dust generated during processing. Next, the distance between the two boxes 2 is adjusted according to the length of the optical film. The extension and retraction of the electric push rod 14 can be controlled to move one of the boxes 2 horizontally. Combined with the guide block 17 and guide groove 18, the box 2 can play a limiting and guiding role during movement. Furthermore, the distance between the two rubber blocks 9 can be adjusted according to the size requirements of the optical film. The worm gear 1502 can be rotated by the screw cap 1504. Combined with the meshing worm wheel 1503, the worm wheel 1503 can be rotated, which in turn drives the lead screw 3 to be adjusted in the forward or reverse direction. Combined with the lead screw nut and guide rod 16, the two sliders 4 can be adjusted in opposite directions, thereby adjusting the two supports 5 and the rubber blocks 9 inside the supports 5 in opposite directions, which facilitates the subsequent pressing, positioning and fixing of the optical film.

[0034] The optical film is then placed on the surface of the table 1, with one side of it in contact with the blocking block 19. Next, the screw rod 1102 is rotated by the knob 1105, which, in conjunction with the limiting rod 1104, moves the rack plate 10 vertically. The upward movement of the rack plate 10, combined with the meshing gear 7, causes the rotating rod 6 and the support plate 8 to rotate synchronously, thereby pressing and fixing the optical film with the rubber block 9. This meets the requirement of pressing and fixing the optical film during processing, effectively preventing displacement that may occur during processing, thus ensuring the accuracy of subsequent processing and significantly reducing the scrap rate. Then, the extension of the electric telescopic column 1302 extends the support rod 1303 and the dust hood 12 to adjust their height for processing the optical film. Finally, the relevant dust removal equipment, combined with the branch pipe 1305, the hose 1306, and the dust hood 12, is controlled to remove the dust generated during processing. After processing, the above steps are repeated to remove the processed optical film.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
