Description

Technical Field

[0001] The utility model relates to the technical field of optical lens processing, in particular to an optical lens side grinding device. Background Technique

[0002] An optical lens is a lens made of optical glass. The definition of optical glass is glass that has specific requirements for optical properties such as refractive index, dispersion, transmittance, spectral transmittance, and light absorption, and has uniform optical properties. It can change the propagation direction of light and can change the relative spectral distribution of ultraviolet, visible, or infrared light. When processing an optical lens, it is necessary to grind the burrs on its side.

[0003] After retrieval, the patent with the publication number CN213795704U discloses an optical lens side grinding device that is easy to adjust. It fixes the lens through a suction cup, and then realizes the extrusion fixation of the two suction cups on the lens by adjusting the overall length of the first fixed shaft and the second fixed shaft. However, since the positions of the pin holes on the first fixed shaft and the second fixed shaft are fixed, it is impossible to ensure that when clamping lenses of different thicknesses, the two suction cups can just clamp the lens; secondly, neither the fixed lens nor the grinding disc can be horizontally moved. Therefore, when grinding, the side of the lens needs to just contact the grinding disc to perform grinding, resulting in poor practicability of the device. In addition, the dust generated during grinding cannot be collected, which will seriously affect the on-site environment. Therefore, further improvement is needed. Content of the Utility Model

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0021] As Figures 1 - 3 shown, it relates to a side grinding device for optical lenses, including a bottom plate 1, a support platform 2 is fixed on one side of the upper surface of the bottom plate 1, a motor 3 is fixed on the lower surface of the support platform 2, the top output shaft of the motor 3 passes through the support platform 2 and is fixedly connected with a support plate 4, an L-shaped support plate 5 is fixed on the upper surface of the bottom plate 1 and close to one side of the support platform 2, a pressing assembly 6 is fixedly installed on the top of the L-shaped support plate 5, a vertical plate 7 is fixed on the upper surface of the bottom plate 1 and far from one side of the support platform 2, a second cylinder 8 is horizontally fixed at the top of the vertical plate 7, the telescopic end of the second cylinder 8 is fixedly connected with a grinding assembly 9, a dust collection assembly 11 is fixed on the upper surface of the bottom plate 1 and below the grinding assembly 9, a hose 10 is connected between the dust collection assembly 11 and the grinding assembly 9, and a negative pressure fan 12 connected to the dust collection assembly 11 is installed on the upper surface of the bottom plate 1.

[0022] The pressing assembly 6 includes a first cylinder 61 fixed on the upper surface of the L-shaped support plate 5, the surface of the bottom telescopic end of the first cylinder 61 is rotatably connected with a sleeve 62 through a bearing, and the bottom end of the sleeve 62 is fixedly connected with a pressing plate 63.

[0023] The first cylinder 61 can drive the pressing plate 63 to descend, so as to press and fix the lens placed on the upper surface of the support plate 4. And because the sleeve 62 is rotatably connected with the telescopic end of the first cylinder 61, it will not affect the motor 3 to drive the support plate 4 and the lens to rotate.

[0024] Rubber pads are fixedly connected to the lower surface of the pressing plate 63 and the upper surface of the supporting plate 4 respectively.

[0025] The rubber pads can increase the friction force between the pressing plate 63, the supporting plate 4 and the lens, ensuring that the motor 3 can drive the lens to rotate stably.

[0026] The grinding assembly 9 includes a housing 91 fixedly connected to the telescopic end of the second cylinder 8. The housing 91 is designed with an open side close to the supporting plate 4. Strip-shaped openings 92 are formed at both ends of the housing 91 close to the open side, and a sandpaper belt 93 is passed through the two strip-shaped openings 92.

[0027] By driving the housing 91 to move towards the lens side through the second cylinder 8, the sandpaper belt 93 is brought into contact with the side of the lens. After the lens rotates, grinding of the side of the lens is achieved.

[0028] On both sides of the outer wall of the housing 91 and close to the strip-shaped openings 92, L-shaped side plates 94 are fixedly installed. A screw rod 95 passes through the middle of the side plate 94 and is threadedly connected. One end of the screw rod 95 inside the side plate 94 is rotatably connected to a clamping plate 96 through a bearing, and a knob is fixed to the other end of the screw rod 95.

[0029] When installing the sandpaper belt 93, after passing the two ends of the sandpaper belt 93 through the two strip-shaped openings 92 respectively, the end of the sandpaper belt 93 is inserted between the clamping plate 96 and the outer wall of the housing 91, and then the screw rod 95 is rotated to drive the clamping plate 96 to squeeze and fix the sandpaper belt 93. When disassembling the sandpaper belt 93, turn the screw rod 95 to drive the clamping plate 96 away from the sandpaper belt 93 to release the squeezing and fixing of the sandpaper belt 93.

[0030] The dust collection assembly 11 includes a box body 111 fixed to the upper surface of the bottom plate 1. One side of the box body 111 is designed with an open side, and a collection box 112 is slidably arranged inside the box body 111. A hose 10 is connected between the top wall of the box body 111 and the bottom wall of the housing 91. A mesh cloth 113 is fixedly connected to the bottom side wall of the collection box 112. A wind hood 114 is fixed to the side wall of the box body 111 and close to the mesh cloth 113, and the wind hood 114 is connected to the air inlet of the negative pressure fan 12.

[0031] After starting the negative pressure fan 12, negative pressure can be pumped into the inside of the collection box 112 through the wind hood 114, and then negative pressure can be pumped into the inside of the housing 91 through the hose 10, so that the dust generated by grinding will not fly everywhere. After the dust is generated, it will stay inside the housing 91 and then enter the collection box 112 along the hose 10. The mesh cloth 113 can prevent the dust from entering the inside of the negative pressure fan 12.

[0032] Working principle: First, place the lens on the upper surface of the pallet 4. Then, start the first cylinder 61 to drive the pressing plate 63 to descend and press-fix the lens. Next, start the motor 3 to drive the lens to rotate. Then, start the second cylinder 8 to drive the housing 91 and the sandpaper belt 93 to approach the lens, so that the sandpaper belt 93 contacts the side of the lens, realizing the grinding of the side of the lens. During the grinding process, start the negative pressure fan 12, so as to suck the dust generated by grinding into the collection box 112 along the hose 10.
