Description

Technical Field

[0001] This utility model relates to the field of light guide plate production technology, specifically a high-efficiency angle grinding device for light guide plate production. Background Technology

[0002] The light guide plate utilizes optical-grade acrylic sheets, then uses a high-tech material with extremely high refractive index and no light absorption to print light guide points on the bottom surface of the optical-grade acrylic sheet using laser engraving, V-shaped cross grid engraving, and UV screen printing technology. The optical-grade acrylic sheet absorbs light emitted from a lamp and causes it to linger on its surface. When the light hits each light guide point, the reflected light diffuses in various angles, breaking the reflection condition and escaping from the front of the light guide plate. Through various density and size light guide points, the light guide plate can emit light uniformly.

[0003] Currently, existing light guide plates require angle grinding equipment for angle grinding during production. A search revealed a utility model patent with prior art authorization announcement number CN219767641U, which discloses an angle grinding device for light guide plate production. This device includes a base plate, a support frame fixedly connected to its upper surface, an X-axis angle grinding drive unit at the top of the support frame, a Y-axis angle grinding drive unit on the X-axis angle grinding drive unit, a Z-axis angle grinding drive unit on the side of the Y-axis angle grinding drive unit, and an angle grinding machine on the Z-axis angle grinding drive unit. A processing table is located on the upper surface of the base plate, and a clamping and positioning mechanism is connected to the upper surface of the processing table. A dustproof cylinder is located on the upper surface of the processing table, and the clamping and positioning mechanisms are located inside the dustproof cylinder. Two clamping and positioning mechanisms are provided.

[0004] Based on the aforementioned patents, the existing technology has the following shortcomings: existing light guide plate grinding equipment generates a large amount of powder during processing. This powder spreads in the working environment as the grinding disc rotates and does not completely fall into the dustproof cylinder, thus causing pollution to the working environment and affecting the health of workers. Therefore, it is urgent to design a high-efficiency light guide plate grinding equipment to solve the above problems. Utility Model Content

[0031] This utility model provides an improved, high-efficiency angle grinding device for light guide plate production. The technical solution of this utility model is as follows:

[0032] In embodiments of this utility model, such as Figures 1-6As shown, a high-efficiency light guide plate production angle grinding equipment includes a chassis 1. An operation port 5 is provided on one side of the top center of the chassis 1, and two limiting plates 3 are installed on the top of the chassis 1 near the operation port 5.

The vacuum cleaner 10... The components, including the corrugated pipe 12, dust extraction pipe 6, dust extraction hood 17, and collection hood 14, effectively collect the dust generated during the angle grinding process, maintaining a clean working environment. The dust exhaust end of the vacuum cleaner 10 is equipped with an air guide pipe 11, and one end of the air guide pipe 11 is fitted with a T-junction. A distribution pipe 7 is installed at the top of the T-junction. One end of the distribution pipe 7 is connected to a flexible hose 9 on one side of the clamping frame 404. An exhaust port 16 is provided on the other side of the clamping frame 404. An exhaust pipe 8 extending out of the housing 1 is installed at one end of the T-junction. Part of the air discharged from the vacuum cleaner 10 is blown onto the surface of the light guide plate through the distribution pipe 7, flexible hose 9, clamping frame 404, and exhaust port 16, further removing residual dust. The angle grinding assembly 13 includes a fixing seat 1301 installed on the inner wall of the top of the housing 1. A mounting frame 1302 is installed at the bottom of 1301. A missing gear 1305 is rotatably connected to the inner wall of the mounting frame 1302. A rotating frame 1307 is installed on one side of the missing gear 1305. A through groove 1308 is opened at one end of the mounting frame 1302. A telescopic rod 1309 passing through the through groove 1308 is inserted into the inner wall of the rotating frame 1307. A tension spring 1315 is installed at one end of the telescopic rod 1309 and at one end of the inner wall of the rotating frame 1307. A mounting base 1310 is installed at the other end of the telescopic rod 1309, and a mounting cylinder 1312 is installed at one end of the mounting base 1310. A drive shaft 1316 is rotatably connected to the inner wall of the mounting cylinder 1312. A motor 1311 for driving the drive shaft 1316 to rotate is fixedly installed at the bottom of the mounting cylinder 1312.A grinding disc 1314 is mounted on the top of the drive shaft 1316. A guide wheel 1313 is rotatably connected to the outer wall of the mounting cylinder 1312 via a bearing, and the guide wheel 1313 is attached to the outer wall of the guide plate 15. A collection cover 14 is mounted on the top of the outer wall of the mounting cylinder 1312. A rack seat 1306 meshes with one side of the missing gear 1305, and a second electric push rod 1303 for driving the rack seat 1306 is mounted on the outer wall of the mounting frame 1302. A guide groove is provided on one side of the rack seat 1306, and a guide strip 1304 attached to the inner wall of the guide groove is mounted on the inner wall of the mounting frame 1302. The second electric push rod 1303 in the grinding assembly 13 drives the rack seat 1306 to move linearly. The rotating mechanism, in conjunction with the meshing of the missing gear 1305 and the rack seat 1306, drives the missing gear 1305, rotating frame 1307, telescopic rod 1309, mounting base 1310, mounting cylinder 1312, and grinding disc 1314 to rotate. Simultaneously, under the action of the tension spring 1315, the guide wheel 1313 moves along the shape of the guide plate 15, allowing the telescopic rod 1309 to extend and retract according to the rotation and position changes of the rotating frame 1307, ensuring the stability and continuity of the overall structure. The motor 1311 drives the drive shaft 1316 and grinding disc 1314 to rotate, enabling the grinding disc 1314 to grind the corners of the light guide plate according to a preset path, thus achieving the corner grinding operation.

[0033] The working principle of the high-efficiency angle grinding equipment for producing light guide plates provided by this utility model is as follows: When in use, the user places the light guide plate to be ground on the top of the machine box 1, and uses two limiting plates 3 to initially position the light guide plate to ensure that the light guide plate is in a suitable processing position. Then, the first electric push rod 402 in the pressing assembly 4 is activated. The piston end of the first electric push rod 402 pushes the lifting plate 403 downward. The lifting plate 403 drives the pressing frame 404 to press down through the buffer spring 405. With the buffering effect of the buffer spring 405, the light guide plate can be stably pressed on the top of the machine box 1 without damaging the light guide plate.

[0034] Next, the user activates the second electric push rod 1303 in the angle grinding assembly 13, which drives the rack seat 1306 to move linearly. Since the missing gear 1305 meshes with the rack seat 1306, the linear motion of the rack seat 1306 is converted into the rotation of the missing gear 1305. When the missing gear 1305 rotates, it drives the rotating frame 1307, the telescopic rod 1309, the mounting base 1310, the mounting cylinder 1312, and the grinding disc 1314 to rotate. At the same time, under the action of the tension spring 1315, the guide wheel 1313 moves along the shape of the guide plate 15, and the telescopic rod 1309 can extend and retract according to the rotation and position change of the rotating frame 1307. The user also starts the motor 1311, which drives the drive shaft 1316 to rotate in the mounting cylinder 1312, which drives the grinding disc 1314 to rotate. This allows the grinding disc 1314 to grind the corner of the light guide plate according to the preset path, thus realizing the angle grinding operation.

[0035] During the polishing process, the user also simultaneously starts the vacuum cleaner 10, which generates suction through the corrugated pipe 12, the dust extraction pipe 6, and the dust extraction hood 17, thereby collecting the dust generated during polishing in a timely manner. When exhausting, some of the gas is discharged outside the housing 1 through the exhaust pipe 8, and the other part of the gas enters the clamping frame 404 through the air distribution pipe 7 and the hose 9, and is discharged from the exhaust hole 16 on the other side of the clamping frame 404. This also plays a role in blowing away dust and preventing dust from accumulating on the surface of the light guide plate during polishing.

[0036] 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.
