[0002] One of the most important purposes of laser lens coating is to increase the transmittance of the lens to a specific wavelength of laser light. In a laser optical system, the uncoated lens will reflect part of the laser light, which not only causes loss of laser energy, but also may cause damage to other elements in the optical system. By coating, the appropriate film layer material and thickness can be selected according to the wavelength of the laser light, so that as much laser light as possible can pass through the lens. By coating multiple layers of high and low refractive index alternating dielectric films, the transmittance of the lens at a wavelength can reach more than 99%.

[0003] The existing clamping device usually uses a mechanical arm and a clamping jaw to clamp the laser lens and move the lens to the frame by the mechanical arm. When the clamping jaw clamps the lens, the lens is clamped at the middle between the two clamping jaws due to the thin thickness of the lens. Therefore, there is a gap between the lens and the end of the clamping jaw, so that the lens does not contact the frame. When the two clamping jaws are loosened, the lens falls freely and drops onto the frame, which causes misalignment between the lens and the frame, and thus the lens is difficult to align accurately with the frame. Therefore, a laser lens coating clamping device is proposed. SUMMARY

[0029] The clamping unit 200 comprises an L-shaped plate 201 fixedly connected to the tail end of the mechanical arm 102, a servo motor 202 fixedly installed on one side of the L-shaped plate 201, an output end of the servo motor 202 penetrating through the L-shaped plate 201 and fixedly connected with a reversible lead screw 203, a connecting plate 204 threadedly sleeved on both ends of the reversible lead screw 203, two sliding grooves are formed in the top of the L-shaped plate 201, a limiting sleeve 205 is slidably arranged in each of the two sliding grooves of the L-shaped plate 201, the two limiting sleeves 205 are fixedly connected with the two connecting plates 204 respectively, an electric telescopic rod 206 is fixedly connected to the top of the L-shaped plate 201, a double T-shaped plate 207 is fixedly connected to the top of the output end of the electric telescopic rod 206, two T-shaped plates 208 are slidably arranged on the top of the double T-shaped plate 207, two clamping plates 209 are fixedly connected to the bottom of the two T-shaped plates 208 respectively, and the two clamping plates 209 are slidably arranged in the two limiting sleeves 205 respectively.

[0030] The mechanical arm 102 is composed of multiple driving shafts and support arms, so that the clamping plates 209 can move in space with a certain degree of freedom, the support column 104 and the support column 104 are used to support the laser glasses, so that the clamping plates 209 can clamp the side wall of the glasses, the support column 104 can be placed in different positions through the circular hole, so as to support glasses of different sizes, when the mechanical arm 102 moves the L-shaped plate 201 above the glasses, the servo motor 202 drives the reversible screw rod 203 to rotate, the two connecting plates 204 are respectively screwed on the opposite threads at the opposite ends of the reversible screw rod 203, the reversible screw rod 203 drives the two connecting plates 204 to move towards each other, the two limiting sleeves 205 are synchronously driven by the two clamping plates 209, the limiting sleeves 205 and the clamping plates 209 are both inverted T-shaped, the two clamping plates 209 can clamp the two sides of the glasses, at this time the glasses are located between the two clamping plates 209, and then the mechanical arm 102 moves;

[0031] During the movement of the two clamping plates 209, the two T-shaped plates 208 slide along the inner wall of the sun-shaped plate 207, when the glasses move above the frame, the sun-shaped plate 207 is driven by the electric telescopic rod 206 to rise, the sun-shaped plate 207 drives the two clamping plates 209 to rise through the two T-shaped plates 208, so that the two clamping plates 209 gradually move into the two limiting sleeves 205, then the side of the glasses abuts against the bottom of the two limiting sleeves 205, so that the glasses gradually move towards the bottom end of the two clamping plates 209, at this time the glasses gradually move towards the surface of the frame through the mechanical arm 102, when the lowest point of the clamping plate 209 is lower than the lowest point of the glasses, the glasses can be in full contact with the frame.

[0032] At this time, the reversible screw rod 203 is driven by the servo motor 202 to rotate in the opposite direction, so that the two clamping plates 209 move away from each other, and the glasses are no longer clamped, so that the glasses can be stably placed in the frame, thereby improving the accuracy of placing the glasses, the sun-shaped plate 207 is driven by the electric telescopic rod 206 to descend, so that the two clamping plates 209 are separated from the inner cavity of the limiting sleeve 205 under the action of gravity, so as to clamp the new glasses again.

[0033] In addition, the bottom of the two clamping plates 209 is fixedly connected with a pair of clamping jaws 210, one side of each clamping jaw 210 is fixedly connected with a rubber pad 211.

[0034] The limiting sleeve 205 can completely accommodate the clamping jaw 210 in the inner cavity of the limiting sleeve 205, the clamping jaw 210 and the rubber pad 211 can clamp the glasses more stably, so that the glasses will not fall off from the clamping jaw 210 during the movement of the mechanical arm 102, thereby improving the stability of clamping.

[0035] Specifically, the opposite faces of the two limiting sleeves 205 are fixedly connected with buffer pads 212, and the lowest points of the buffer pads 212 are lower than the lowest points of the limiting sleeves 205.

[0036] When the electric telescopic rod 206 drives the clamping plate 209 to rise through the sun plate 207 and the T plate 208, the clamping jaws 210 clamping the lenses also move into the limiting sleeves 205. During the process of the lenses rising with the clamping jaws 210, the lenses first contact the two buffer pads 212, which can reduce the damage to the lenses. The buffer pads 212 prevent the lenses from moving, so that the lenses are separated from the two pairs of clamping jaws 210 and stably stay on the frame.

[0037] Further, the opposite faces of the two limiting sleeves 205 are fixedly connected with a horizontal plate 213, the bottom of the horizontal plate 213 is slidingly penetrated by an I-shaped rod 214, the opposite faces of the I-shaped rod 214 and the L-shaped plate 201 are fixedly connected with a spring 215, and the bottom end of the I-shaped rod 214 is fixedly connected with an air bag 216.

[0038] When the clamping jaws 210 clamping the lenses move into the limiting sleeves 205, the I-shaped rod 214 can support the middle part of the lenses, so that the lenses are limited by the I-shaped rod 214 and keep a horizontal relative direction with the frame when the lenses slide between the two pairs of clamping jaws 210. The I-shaped rod 214 can prevent the lenses from deviating during the sliding process, so as to ensure that the lenses stably stay on the frame.

[0039] The air bag 216 can provide flexible protection between the I-shaped rod 214 and the lenses. When the air bag 216 contacts the lenses, the air bag 216 is subjected to an interaction force, thereby driving the I-shaped rod 214 to rise along the horizontal plate 213 and press the spring 215. The spring 215 can provide resistance to the I-shaped rod 214, so as to correct the position of the lenses and prevent the lenses from deviating.

[0040] Further, the top of each support column 104 is threadedly connected with a ball head rod 105, and the ball head end of the ball head rod 105 is made of rubber.

[0041] The length of the support column 104 and the ball head rod 105 can be adjusted by rotating the ball head rod 105. The ball head rod 105 with different heights can stably support the concave or convex non-planar lenses, so as to facilitate clamping. The ball head end of the ball head rod 105 is made of rubber, so as to prevent the ball head rod 105 from scratching the lenses and increase the friction between the ball head rod 105 and the lenses, so that the lenses will not slide off the ball head rod 105.

[0042] During use, the length of the support column 104 and the ball head rod 105 is adjusted by rotating the ball head rod 105, then a different number of support columns 104 are inserted into the corresponding circular holes in the support seat 103, and the laser lens is placed on the top of the plurality of ball head rods 105, then the L-shaped plate 201 is moved above the lens by the mechanical arm 102, then the servo motor 202 is started to drive the forward and reverse toothed rod 203 to rotate, so that the two connecting plates 204 drive the two limiting sleeves 205 to move close to each other, the two limiting sleeves 205 synchronously drive the two clamping plates 209 to move close to each other, the lens is clamped by the two pairs of clamping jaws 210, then the lens is moved by the mechanical arm 102, when the lens is moved above the frame, the I-shaped plate 207 is driven to rise by the electric telescopic rod 206.

[0043] The I-shaped plate 207 drives the two clamping plates 209 to rise by the two T-shaped plates 208, so that the two pairs of clamping jaws 210 gradually move into the two limiting sleeves 205, in the process of the lens rising with the clamping jaws 210, the air bag 216 contacts the lens, the air bag 216 drives the I-shaped rod 214 to rise along the horizontal plate 213 and press the spring 215, the position of the lens is corrected by the I-shaped rod 214, so that the lens does not deviate, when the lens contacts the two buffer pads 212, the buffer pads 212 prevent the lens from moving, so that the lens slides down between the two pairs of clamping jaws 210, when the lowest point of the clamping plate 209 is lower than the lowest point of the lens, the lens can fully contact the frame, at this time, the servo motor 202 is driven to rotate the forward and reverse toothed rod 203 in the opposite direction, so that the two clamping plates 209 move away from each other, the lens is no longer clamped, so that the lens can be stably placed in the frame, thereby improving the accuracy of lens placement.
