Technical Field

[0001] This utility model relates to the field of filter manufacturing technology, specifically to a chamfering device for filter manufacturing. Background Technology

[0002] Light filters are used to selectively allow light of a specific wavelength range to pass through while blocking light of other wavelengths. They play a very important role in the fields of photography and videography, determining the imaging effect of photographs and cameras.

[0003] Chamfering during filter production removes sharp edges, reducing the risk of breakage during installation or use, and also reduces edge scattering, improving image quality. However, when chamfering rectangular filters, the filters must first be positioned and clamped, which can cause partial obstruction of the filter's edges, preventing the process from being completed in one go and requiring disassembly and repositioning. Therefore, this invention proposes a chamfering device for filter production that can solve the above problems. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-5

[0024] Provides a chamfering device for filter production:

[0025] The grinding motor 40 is mounted on the fixed frame 10. The output end of the grinding motor 40 is connected to the grinding wheel 41. The grinding motor 40 drives the grinding wheel 41 to rotate, which can perform chamfering on the rectangular filter.

[0026] The movable frame 20 is connected to the fixed frame 10 via a lifting cylinder 11. The lifting cylinder 11 can drive the movable frame 20 to move vertically. The straight column 30 is rotatably connected to the movable frame 20. An adjusting motor 21 that drives the straight column 30 to rotate is installed on the fixed frame 10 of the movable frame 20. The straight column 30 has a bushing 31. The adjusting motor 21 has a self-locking function. The adjusting motor 21 drives the straight column 30 to rotate to a position so that the straight column 30 can drive the bushing 31 to maintain a fixed angle.

[0027] The support frame 31 is provided with a rotating part, and the rotating part is connected to a support plate 34. The support plate 34 can be replaced as needed. The support plate 34 is used to place the rectangular filter to be polished. The rotating part includes a rotary motor 32 and a support shaft 33. The rotary motor 32 has a self-locking function. The rotary motor 32 is used to drive the support shaft 33 to drive the support plate 34 to rotate and adjust the direction. That is, the position of the rectangular filter to be chamfered can be adjusted so that the chamfered side of the rectangular filter to be processed faces down.

[0028] The front side of the support plate 34 has a first positioning edge 341 and a second positioning edge 342. The first positioning edge 341 is perpendicular to the second positioning edge 342. The support plate 34 is connected to an abutting edge 343 through the movable part 37. The abutting edge 343 cooperates with the first positioning edge 341 and the second positioning edge 342 to abut against the outer wall of the filter and expose the chamfered edge of the filter. This avoids obstructing part of the edge of the filter, eliminates the need for multiple disassembly and reassembly adjustments, and improves processing efficiency.

[0029] Specifically, during production and processing, in the first stage: the motor 21 is adjusted to drive the support column to rotate, so that the straight column 30 can drive the bushing 31 to keep it horizontal. At this time, the front side of the support plate 34 is in a vertical state. The rectangular filter is positioned and placed through the first positioning edge 341 and the second positioning edge 342. Then, the abutting edge 343 abuts against the filter through the movable part 37. After the filter is placed, the motor 21 is adjusted to drive the support column to rotate, and the bushing 31 drives the filter to maintain a fixed angle, such as 45°.

[0030] Second stage: The lifting cylinder 11 drives the movable frame 20 to move downward, so that one side of the filter contacts the grinding wheel 41 for processing. After processing one side, the lifting cylinder 11 drives the movable frame 20 to move upward. The rotary motor 32 drives the support shaft 33 to rotate, which in turn drives the bearing plate 34 to rotate and adjust the direction so that the unprocessed side of the filter faces downward. Then, the lifting cylinder 11 drives the movable frame 20 to move downward again, so that the chamfering of the rectangular filter is completed in one go. After processing is completed, the adjustment motor 21 drives the support column to rotate, so that the straight column 30 can drive the bushing 31 to keep it horizontal, and the chamfered filter is removed.

[0031] During the chamfering process, the height at which the lifting cylinder 11 drives the movable frame 20 to descend is controlled according to the corresponding edge of the filter being processed.

[0032] A linear cylinder 36 is mounted on the bushing 31. The movable rod 371 of the linear cylinder 36 is connected to a support rod 361. The support rod 361 is connected to a cover plate 362. The cover plate 362 is used to press the outside of the filter. The cover plate 362 has multiple sets of ball bearings. The cover plate 362 is smaller than the filter. During processing, after the chamfered side of the filter is turned downwards, the ball bearings on the cover plate 36 are driven by the linear cylinder 36 to press the filter, further improving the stability of the processing.

[0033] A liquid pipe is provided on the fixed frame 10. The liquid pipe is used to transport coolant to the grinding wheel 41 to cool the grinding wheel 41.

[0034] The movable frame 20 is provided with a partition 35, and a sliding groove is provided on the inner wall of the partition 35. The liner 31 is provided with a slider, which slides into the sliding groove to guide the movement of the liner 31.

[0035] The movable part 37 includes a through groove formed in the support plate 34 and a movable rod 371 screwed to the support plate 34. The abutment edge 343 is slidably engaged with the through groove. The movable rod 371 is connected to an abutment block 372 extending into the through groove. The abutment block 372 is conical. By rotating the movable rod 371, the abutment block 372 pushes the abutment edge 343 to move, thereby causing the filter to abut. 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 variations 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.
