Description

Technical Field

[0001] This utility model belongs to the technical field of lens processing equipment, and specifically relates to a lens limiting device for lens processing and cleaning. Background Technology

[0002] To improve the quality of optical lenses, they usually need to be cleaned. Optical lens cleaning is a process that uses an ultrasonic cleaner to remove organic and inorganic dirt from the surface of the parts.

[0003] Currently, lens clamps are commonly used to fix lenses in place for cleaning. However, most lens clamps have limited adjustment range. When it is necessary to clamp lenses that are too large or too small, it is inconvenient to adjust the clamping distance. Furthermore, the clamping is not secure during the cleaning process, causing the lenses to loosen or fall off, thus affecting the cleaning effect. Utility Model Content

[0004] To overcome the limitations of most lens clamps in the prior art, such as limited adjustment range, inconvenience in adjusting the clamping distance when clamping lenses of varying sizes, and instability during cleaning leading to lens loosening or detachment and affecting cleaning results, this invention provides a lens limiting device for lens processing and cleaning. By using a positioning frame in conjunction with a limiting frame and an adjusting component, the lens edge is simultaneously supported by the positioning frame and pressure from the pressure rod, forming a three-point clamping force balance. This effectively improves the stability of lens clamping, preventing lens loosening or detachment under ultrasonic high-frequency vibration, thus ensuring cleaning results. Furthermore, the adjusting component allows for flexible adjustment of the distance between the limiting frame and the positioning frame, adapting to the clamping needs of lenses of different sizes and increasing the device's versatility.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A lens limiting device for lens processing and cleaning mainly includes a base, a positioning frame, an adjustment component, and a limiting frame. Multiple positioning frames for placing lenses are equidistantly installed on the base. Each positioning frame includes two support rods mounted on the base and inverted V-shaped positioning rods equidistantly distributed along the axial direction of the support rods. The limiting frame is mounted on the base via the adjustment component. The limiting frame includes a rectangular frame, on which pressure rods for fixing lenses are equidistantly arranged, with the pressure rods located directly above the tips of the V-shaped positioning rods. The adjustment component includes a scissor bracket, a connecting rod, a threaded rod, a handwheel, and a connecting block. A straight slot is horizontally opened on the side wall of the base. The end of the connecting rod is slidably installed in the straight slot. One support rod of the scissor bracket has its bottom end hinged to the base and its top end hinged to the rectangular frame. The other support rod has its bottom end hinged to the end of the connecting rod and its top end hinged to the rectangular frame. A connecting block is provided in the middle of the connecting rod. One end of the threaded rod is rotatably installed on the connecting block, and the other end passes through the side wall of the base and is connected to the handwheel.

[0006] Both the positioning frame and the limiting frame are integrally formed from corrosion-resistant aluminum alloy, and the surfaces of the pressure rod and the V-shaped positioning rod are covered with an anti-slip silicone layer.

[0007] The positioning frames are arranged equidistantly along the base, and a gap area is provided between adjacent positioning frames to prevent interference between the edges of the two lenses.

[0008] The base has a U-shaped groove on its side wall for easy manual gripping.

[0009] The beneficial effects of this utility model are:

[0010] This invention utilizes a positioning frame, a limiting frame, and an adjustment component to simultaneously support the lens edge with the positioning frame and press with the pressure rod, creating a three-point clamping force balance. This effectively improves the stability of lens clamping and prevents the lens from loosening or falling off under ultrasonic high-frequency vibration, thus ensuring the cleaning effect. At the same time, the adjustment component allows for flexible adjustment of the distance between the limiting frame and the positioning frame, adapting to the clamping needs of lenses of different sizes and increasing the versatility of the device.

[0017] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0018] This utility model discloses a lens limiting device for lens processing and cleaning. The lens limiting device mainly includes a base 1, positioning frames 2, adjusting components 3, and limiting frames 4. Multiple sets of positioning frames 2 for placing lenses are equidistantly installed on the base 1. Each positioning frame 2 includes two support rods 201 mounted on the base 1 and inverted V-shaped positioning rods 202 equidistantly distributed along the axial direction of the support rods 201. The limiting frames 4 are mounted on the base 1 via the adjusting components 3. Each limiting frame 4 includes a rectangular frame 401, on which pressure rods 402 for fixing lenses are equidistantly arranged. The pressure rods 402 are located at the tips of the V-shaped positioning rods 202. Directly above; the adjustment component 3 includes a scissor bracket 301, a connecting rod 302, a threaded rod 303, a handwheel 304, and a connecting block 305. A straight slot 101 is horizontally opened on the side wall of the base 1. The end of the connecting rod 302 is slidably installed in the straight slot 101. The bottom end of one support rod of the scissor bracket 301 is hinged to the base 1, and the top end is hinged to the rectangular frame 401. The bottom end of the other support rod is hinged to the end of the connecting rod 302, and the top end is hinged to the rectangular frame 401. A connecting block 305 is provided in the middle of the connecting rod 302. One end of the threaded rod 303 is rotatably installed on the connecting block 305, and the other end passes through the side wall of the base 1 and is connected to the handwheel 304.

[0019] In use, the lens to be cleaned is placed between the V-shaped positioning rods 202 of the positioning frame 2. The lens edge is supported by two support rods 201, and the lens is automatically centered and kept stable under the positioning action of the V-shaped positioning rods 202. After the lens is placed, the operator rotates the handwheel 304, which drives the threaded rod 303 to rotate. The rotation of the threaded rod 303 pushes the connecting block 305 to move, which in turn drives the connecting rod 302 to slide within the straight groove 101. The movement of the connecting rod 302 changes the included angle of the scissor bracket 301, thereby adjusting the distance between the limiting frame 4 and the positioning frame 2. When the limiting frame 4 moves downward, the pressure rod 402 gradually approaches the lens and finally presses against the top edge of the lens. At this time, the edge of the lens is simultaneously subjected to the supporting force of the positioning frame 2 and the pressure of the pressure rod 402, forming a three-point clamping force balance, so that the lens is firmly fixed in the limiting device. After the lens is fixed, the device is placed in the cleaning machine for cleaning. Because the lens is firmly clamped, it will not loosen or fall off under the high-frequency vibration of ultrasonic waves, thus ensuring the cleaning effect. This utility model achieves stable clamping and flexible adjustment of the lens through the synergistic effect of the positioning frame, the limiting frame and the adjustment component, which can adapt to the clamping needs of lenses of different sizes and improve the efficiency and quality of lens processing and cleaning.

[0020] Both the positioning frame 2 and the limiting frame 4 are integrally formed from corrosion-resistant aluminum alloy. The surfaces of the pressure rod 402 and the V-shaped positioning rod 202 are covered with an anti-slip silicone layer. The anti-slip silicone layer is soft and can prevent the pressure rod 402 and the V-shaped positioning rod 202 from directly contacting the lens, thereby reducing damage and scratches to the lens surface.

[0021] The positioning frame 2 is arranged equidistantly along the base 1 in the transverse direction, and a gap area is provided between adjacent positioning frames 2 to prevent interference between the edges of the two side lenses.

[0022] The base 1 has a U-shaped groove 102 on its side wall for easy manual gripping.

[0023] Work process:

[0024] In use, the lens to be cleaned is placed between the V-shaped positioning rods 202 of the positioning frame 2. The lens edge is supported by two support rods 201, and the lens is automatically centered and kept stable under the positioning action of the V-shaped positioning rods 202. After the lens is placed, the operator rotates the handwheel 304, which drives the threaded rod 303 to rotate. The rotation of the threaded rod 303 pushes the connecting block 305 to move, which in turn drives the connecting rod 302 to slide within the straight groove 101. The movement of the connecting rod 302 changes the included angle of the scissor bracket 301, thereby adjusting the distance between the limiting frame 4 and the positioning frame 2. When the limiting frame 4 moves downward, the pressure rod 402 gradually approaches the lens and finally presses against the top edge of the lens. At this time, the edge of the lens is simultaneously subjected to the supporting force of the positioning frame 2 and the pressure of the pressure rod 402, forming a three-point clamping force balance, so that the lens is firmly fixed in the limiting device. After the lens is fixed, the device is placed in the cleaning machine for cleaning. Because the lens is firmly clamped, it will not loosen or fall off under the high-frequency vibration of ultrasonic waves, thus ensuring the cleaning effect. This utility model achieves stable clamping and flexible adjustment of the lens through the synergistic effect of the positioning frame, the limiting frame and the adjustment component, which can adapt to the clamping needs of lenses of different sizes and improve the efficiency and quality of lens processing and cleaning.
