Description

Technical Field

[0001] The present invention relates to the technical field of lens processing equipment, and in particular to a precision lens and a coating device thereof. Background Art

[0002] In the field of modern optics, precision lenses, as core components of imaging and optical transmission, are widely used in high-tech products such as camera lenses, video camera lenses, microscopes, security lenses, and medical equipment. These lenses not only require extremely high optical performance, but also must achieve extremely high precision and surface quality during the manufacturing process.

[0003] In the prior art, when coating a lens, due to the requirements of precision and cleanliness of the lens, manual adjustment is often used when adjusting the coating on the other side of the lens, which not only affects the coated surface of the lens, but also affects the cleanliness of the uncoated surface of the lens. At the same time, due to the precipitation characteristics of the coating liquid, when coating the lens, it is often necessary to constantly ensure that the coating liquid is fully mixed. Therefore, the above problems are not solved, and we provide a precision lens and a coating device thereof. Summary of the invention

[0004] The present invention aims to solve the technical problem of how to adjust the position of the lens when the device is coating the lens, so that lenses of different sizes correspond to spray heads of different sizes, avoiding waste of coating liquid, and automatically switching the mirror surface of the lens, and stirring the coating liquid before coating to prevent precipitation. A precision lens and its coating device are provided.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a precision lens and its coating device, including: a lens coating adjustment device, a coating clamping device, a coating liquid storage device, a controller, and a shell.

[0006] The housing is arranged on the ground. The lens coating adjustment device is arranged inside the housing and fixedly connected to the inner wall of the housing. The coating clamping device is arranged inside the housing and connected to the inner wall of the housing and the lens coating adjustment device. The coating liquid storage device is arranged on the side of the housing and connected to the housing and the coating clamping device. The controller is arranged on the side of the housing and on the ground, and the controller is electrically connected to the lens coating adjustment device, the coating clamping device, and the coating liquid storage device.

[0007] When the user wants to coat the lens, the user first opens the housing, and then places the lens on the lens coating adjustment device. Then, the user starts the lens coating adjustment device through the controller. When the lens coating adjustment device is started, the lens coating adjustment device moves to adjust the position of the lens so that the lens can be under the coating liquid nozzle of the appropriate size. When the lens coating adjustment device drives the lens to move, the lens coating adjustment device drives the coating liquid storage device through the coating clamping device to stir the coating liquid, so that the coating liquid will not lose its working performance due to precipitation.

[0008] At the same time, the user can operate the lens coating adjustment device through the controller to stop supporting the lens, thereby driving the coating clamping device to clamp the lens. After clamping is completed, the user can start the lens coating adjustment device again through the controller to coat the clamped lens. After coating is completed, the user can start the lens coating adjustment device again to drive the coating clamping device to stop clamping the lens and drive the lens to rotate, so that the coating liquid dripping on the surface of the lens can be evenly spread on the surface of the lens under the action of centrifugal force and wait for the coating liquid to evaporate.

[0009] After coating one side of the lens, the user can start the lens coating adjustment device through the controller again to drive the coating clamping device to coat the lens again. After coating, the user can control the lens coating adjustment device to adjust the position through the controller, so that the coating clamping device can drive the lens to rotate, so that the lens can rotate from the coated side to the uncoated side. At the same time, the coating clamping device will drive the coating liquid storage device to stir the coating liquid, and then the user can start the lens coating adjustment device through the controller to coat the uncoated side of the lens until the coating liquid is evenly spread and evaporated, so as to complete the coating of the lens.

[0010] With such a working setting, when the equipment is coating the lens, the equipment can adjust the position of the lens so that lenses of different sizes correspond to spray heads of different sizes, avoiding waste of coating liquid. At the same time, it can also automatically switch the mirror surface of the lens and stir the coating liquid before coating to prevent precipitation.

[0011] Furthermore, the lens coating adjustment device includes: a rotating and telescopic motor, a plurality of spray heads, a driving motor, a threaded rod, a spray pipe, a transverse plate, a carrying plate, and two rectangular blocks.

[0012] The drive motor is arranged at the rear of the shell, and its rotating shaft passes through the back of the shell and extends to the inside of the shell. The shell of the drive motor is fixedly connected to the back of the shell, and the rotating shaft is rotatably connected to the back of the shell. The rotating axis is perpendicular to the back of the shell, and the drive motor is electrically connected to the controller.

[0013] The two rectangular blocks are respectively arranged inside the shell and are located on both sides of the rotating shaft of the driving motor. The bottom surfaces of the two rectangular blocks are respectively fixedly connected to the inner bottom surface of the shell, and the two end surfaces of the two rectangular blocks are respectively fixedly connected to the inner front and back surfaces of the shell.

[0014] The threaded rod is arranged horizontally inside the shell and between the two rectangular blocks. One end of the threaded rod is fixedly connected to the end face of the rotating shaft of the driving motor, and the other end is rotatably connected to the front face of the shell. The rotating axis coincides with the rotating axis of the driving motor.

[0015] The transverse plate is arranged inside the shell and above the two rectangular blocks. The bottom surface of the transverse plate is slidably connected to the top surfaces of the two rectangular blocks. The sliding direction is parallel to the axis of the threaded rod. A threaded sleeve is arranged on the bottom surface of the transverse plate, and is sleeved on the threaded rod and threadedly connected to the threaded rod. The top surface of the transverse plate is also connected to the coating clamping device.

[0016] The rotary telescopic motor is arranged inside the shell and above the transverse plate. The bottom surface of the rotary telescopic motor is fixedly connected to the top surface of the transverse plate and is electrically connected to the controller.

[0017] The carrying plate is arranged inside the outer shell and above the rotating and telescopic motor. The bottom surface of the carrying plate is fixedly connected to the end surface of the telescopic rotating shaft of the rotating and telescopic motor. A suction cup is arranged on the top surface of the carrying plate, and the adsorption surface of the suction cup faces the inner top surface of the outer shell, and is connected to the vacuum machine through an air pipe. The vacuum machine is electrically connected to the controller, and the carrying plate is also connected to the coating clamping device.

[0018] The spray pipe is arranged inside the shell and above the carrying plate. The spray pipe is fixedly connected to the inner top surface of the shell and is connected to the inside of the coating liquid storage device through a pipeline penetrating the side wall of the shell.

[0019] The plurality of spray heads are respectively arranged inside the shell and between the spray pipe and the supporting plate. The plurality of spray heads are respectively arranged equidistantly below the spray pipe and respectively penetrate the side wall of the spray pipe and communicate with the inside of the spray pipe. The plurality of spray heads are also respectively electrically connected to the controller, and the plurality of spray heads are of different sizes.

[0020] When the user wants to coat the lens, the user first places the lens on the carrier plate, and then the user starts the retraction of the rotary telescopic motor through the controller. When the rotary telescopic motor retracts, the carrier plate is driven down, and the carrier plate is driven down to drive the coating clamping device to clamp the lens. When the coating clamping device has finished clamping the lens, the user can control the drive motor to rotate forward through the controller. After the drive motor rotates forward, the drive motor drives the threaded rod to rotate forward, and the threaded rod drives the transverse plate to move forward. The transverse plate moves forward and drives the rotary telescopic motor, the carrier plate, the coating clamping device, and the lens to move forward and drive the coating clamping device to rotate until the lens moves to the bottom of the spray head that matches the size of the lens. When the coating clamping device rotates, the coating clamping device drives the lens to rotate. When the lens is under the corresponding spray head, the user starts the spray head corresponding to the lens again through the controller. After the corresponding spray head is started, the spray head can spray the coating liquid inside the spray pipe onto the mirror surface of the lens below it.

[0021] After the coating liquid is sprayed, the user can control the rotary telescopic motor to start and extend through the controller. The extension of the rotary telescopic motor drives the carrying plate to rise. The rising of the carrying plate drives the coating clamping device to stop clamping the lens and make the lens fall on the carrying plate. Then the user starts the vacuum machine through the controller to adsorb the lens on the carrying plate, and starts the rotary telescopic motor to rotate. The rotation of the rotary telescopic motor drives the carrying plate to rotate. The rotation of the carrying plate drives the lens to rotate and drives the lens clamping device to move. The coating liquid on the surface of the lens will be evenly spread on the surface of the lens under the action of centrifugal force, so as to complete the uniform coating of the coating liquid and accelerate the evaporation.

[0022] When the coating of one side of the lens is completed, the user can stop the vacuum machine through the controller and start the retracting of the rotary telescopic motor. The vacuum machine stops working so that the carrier plate stops adsorbing the lens. The retraction of the rotary telescopic motor drives the carrier plate to descend, and the descent of the carrier plate drives the coating clamping device to clamp the lens. When the coating clamping device completes clamping the lens, the user can control the driving motor to start forward rotation through the controller again. The forward rotation of the driving motor drives the threaded rod to rotate forward, and the forward rotation of the threaded rod drives the transverse plate to move forward. The forward movement of the transverse plate drives the rotary telescopic motor, the carrier plate, the coating clamping device, and the lens to move forward together and bring The coating clamping device is driven to rotate. When the coating clamping device moves forward, it drives the clamped lens to move forward and rotate until the other uncoated side of the clamped lens faces the matching spray head. Then the user controls the driving motor to reverse through the controller. The driving motor reverses and drives the threaded rod to reverse. The threaded rod reverses and drives the transverse plate to move in the opposite direction. The transverse plate moves in the opposite direction and drives the rotating telescopic motor, the coating clamping device, and the lens to move in the opposite direction, but does not drive the coating clamping device to rotate. In this way, the lens that has completed the mirror switching can be moved again to the bottom of the matching spray head, so as to complete the function of switching the uncoated lens of the lens. Then the user can start the rotating telescopic motor and the matching spray head through the controller again to complete the function of coating the uncoated side of the lens.

[0023] Furthermore, the coating clamping device includes: a vertical plate, a return spring, a moving block, an adjusting rotation mechanism, two adjustable clamping mechanisms, a vertical bearing rod, two elliptical rings, a driving rod, a sliding pin, a sliding groove, a sliding block, and a connecting rod.

[0024] The vertical plate is arranged inside the shell, and is located on the side of the rotary telescopic motor and above the horizontal plate. The bottom surface of the vertical plate is fixedly connected to the top surface of the horizontal plate.

[0025] The sliding groove is arranged on the side of the carrying plate and is arranged around the axis of the carrying plate. The first positions of the sliding grooves are connected to form the sliding grooves.

[0026] The sliding block is arranged inside the sliding groove and is slidably connected with the inner side surface of the sliding groove, and the sliding direction is sliding around the axial direction of the carrying plate.

[0027] The driving rod is arranged inside the shell and is obliquely arranged between the sliding block and the vertical plate. The top end of the driving rod is fixedly connected to the side surface of the sliding block.

[0028] The two elliptical rings are arranged obliquely inside the shell, between the sliding block and the vertical plate and on the top surface of the horizontal plate. The two elliptical rings are arranged on both sides of the inclined bottom end of the driving rod and are fixedly connected to the top surface of the horizontal plate through the support rod.

[0029] The sliding pin is transversely arranged between the two elliptical rings, and both ends pass through the interior of the two elliptical rings respectively and extend to the outer sides of the two elliptical rings. The side surface of the sliding pin is also fixedly connected to the inclined lowest end of the driving rod.

[0030] The return spring is transversely arranged inside the shell, above the rotary telescopic motor and beside the vertical plate, and one end of the return spring is fixedly connected to the side of the vertical plate close to the rotary telescopic motor.

[0031] The moving block is arranged inside the shell and between the carrying plate and the vertical plate, and the side surface of the moving block is fixedly connected to the other end of the return spring.

[0032] The connecting rod is arranged inside the shell, below the moving block and between the two elliptical rings, one end of the connecting rod is fixedly connected to the side surface of the sliding pin, and the other end is fixedly connected to the bottom surface of the moving block.

[0033] The vertical bearing rod is arranged inside the shell and is located on the side of the bearing plate away from the vertical plate. The bottom end of the vertical bearing rod is fixedly connected to the top surface of the horizontal plate.

[0034] The adjusting and rotating mechanism is arranged inside the shell and above the vertical bearing rod, and the adjusting and rotating mechanism is connected to the top end of the vertical bearing rod.

[0035] Two adjustable clamping mechanisms are respectively arranged inside the shell and above the carrying plate. One of the adjustable clamping mechanisms is rotatably connected to the side of the moving block close to the carrying plate, and the rotation axis is perpendicular to the axis of the rotating telescopic motor. The other adjustable clamping mechanism is connected to the adjusting rotation mechanism. The two adjustable clamping mechanisms are in the same straight line and are electrically connected to the controller respectively.

[0036] When the carrying plate descends, the carrying plate drives the driving rod to descend, and the driving rod drives the sliding pin to descend in the two elliptical rings. The sliding pin drives the connecting rod to descend, and the connecting rod pulls the moving block to move toward the carrying plate. The movement of the moving block drives one of the adjustable clamping mechanisms to move and stops applying pressure to the reset spring so that the reset spring can recover. At the same time, one of the adjustable clamping mechanisms moves to drive the lens to contact with the other adjustable clamping mechanism until the carrying plate descends to the lowest point driven by the rotating telescopic motor, and the two adjustable clamping mechanisms can firmly fix the lens.

[0037] When the carrying plate rises, the carrying plate rises and drives the driving rod to rise. The driving rod rises and drives the sliding pin to rise in the two elliptical rings. The sliding pin rises and drives the connecting rod to rise. The connecting rod rises and pulls the moving block to move away from the carrying plate. The movement of the moving block drives one of the adjustable clamping mechanisms to move and exerts pressure on the reset spring, so that the reset spring can be shortened. At the same time, the movement of one of the adjustable clamping mechanisms will stop exerting pressure on the lens to contact the other adjustable clamping mechanism, and the lens will fall on the carrying plate again until the carrying plate rises to the highest point driven by the rotating telescopic motor, and one of the adjustable clamping mechanisms can return to its original position.

[0038] When the carrier plate rotates, the rotation of the carrier plate drives the lens to rotate, and drives the sliding block to slide in the sliding groove. When the sliding block slides in the sliding groove, the sliding block can always maintain the current position relative to the driving rod in the sliding groove.

[0039] The user can control the size of the adjustable clamping mechanism through the controller to adapt to lenses of different radius sizes.

[0040] When the transverse plate moves forward, the positive movement of the transverse plate drives the vertical plate, the vertical bearing rod, and another adjustable clamping mechanism to move forward, and at the same time, the driving rod, the sliding block, the sliding pin, the two elliptical rings, the connecting rod, the moving block, the reset spring, and the adjusting rotating mechanism to move forward by rotating the telescopic motor and the bearing plate, so that the two adjustable clamping mechanisms can drive the clamped lenses to move forward. At the same time, when the adjusting rotating mechanism moves forward, the adjusting rotating mechanism can drive the other adjustable clamping mechanism to rotate forward, so that one of the adjustable clamping mechanisms can be driven to rotate through the lens, so that the lens can be rotated from the coated side to the uncoated side.

[0041] When the transverse plate moves in the reverse direction, the transverse plate moves forward and drives the vertical plate, the vertical bearing rod and the other adjustable clamping mechanism to move in the reverse direction, and at the same time drives the driving rod, the sliding block, the sliding pin, the two elliptical rings, the connecting rod, the moving block, the reset spring and the adjusting rotating mechanism to move in the reverse direction by rotating the telescopic motor and the bearing plate, so that the two adjustable clamping mechanisms can drive the clamped lenses to move in the reverse direction, and at the same time, when the adjusting rotating mechanism moves in the reverse direction, the adjusting rotating mechanism can drive the other adjustable clamping mechanism to rotate in the reverse direction, and the adjustable clamping mechanism will not drive the other adjustable clamping mechanism to rotate when it moves in the reverse direction.

[0042] Furthermore, the regulating rotation mechanism includes: a transverse rotating rod, a rotating connecting sleeve, a one-way clutch, a gear, a raised plate, and a rack.

[0043] The rotating connecting sleeve is arranged inside the shell and is located on the side of the bearing plate away from the moving block. The bottom surface of the rotating connecting sleeve is fixedly connected to the top surface of the vertical bearing rod.

[0044] The transverse rotating rod is arranged inside the shell and is located on the side of the moving block away from the vertical plate. One end of the transverse rotating rod passes through the shaft sleeve of the rotating connecting sleeve and is connected to the coating liquid storage device. The other end of the transverse rotating rod is fixedly connected to another adjustable clamping mechanism.

[0045] The raised plate is arranged inside the shell, on the side of the rotating connecting sleeve close to the inner side of the shell and below the transverse rotating rod. One side of the raised plate is fixedly connected to the side of the shell, and the two end surfaces are respectively fixedly connected to the inner front and back of the shell.

[0046] The one-way clutch is sleeved on the transverse rotating rod and is located on the side of the coating liquid storage device close to the rotating connecting sleeve and above the raised plate. The one-way clutch is fixedly connected to the side of the transverse rotating rod.

[0047] The gear sleeve is arranged on the outer side surface of the one-way clutch and is fixedly connected with the outer side surface of the one-way clutch.

[0048] The rack is arranged inside the shell, above the raised plate and below the gear. The rack is fixedly connected to the top surface of the raised plate and meshes with the gear.

[0049] When the vertical bearing rod moves forward, the forward movement of the vertical bearing rod drives the forward movement of the rotating connecting sleeve, the forward movement of the rotating connecting sleeve drives the forward movement of the transverse rotating rod, the forward movement of the transverse rotating rod drives another adjustable clamping mechanism to move forward, and at the same time drives the one-way clutch to move forward, the forward movement of the one-way clutch drives the gear to move forward, and the gear will rotate forward along the rack when moving forward, the forward rotation of the gear drives the one-way clutch to rotate forward, the forward rotation of the one-way clutch drives the transverse rotating rod to rotate forward, the forward rotation of the transverse rotating rod drives another adjustable clamping mechanism to rotate, and drives the coating liquid storage device to operate. In this way, the coated surface of the lens is adjusted to the uncoated surface.

[0050] When the vertical bearing rod moves in the reverse direction, the reverse movement of the vertical bearing rod drives the rotating connecting sleeve to move in the reverse direction, the reverse movement of the rotating connecting sleeve drives the transverse rotating rod to move in the reverse direction, the reverse movement of the transverse rotating rod drives another adjustable clamping mechanism to move in the reverse direction, and at the same time drives the one-way clutch to move in the reverse direction, the reverse movement of the one-way clutch drives the gear to move in the reverse direction, and the gear will rotate in the reverse direction along the rack when moving in the reverse direction, and the reverse rotation of the gear will not drive the one-way clutch to rotate, so as to avoid the lens being adjusted to the uncoated surface and then rotating again when the position of the lens is adjusted to adjust to the coated surface.

[0051] Furthermore, the coating liquid storage device includes: a connecting tank, a coating liquid tank, a plurality of stirring blades, a liquid outlet valve, and a liquid inlet.

[0052] The coating liquid tank is arranged on the side of the shell and is located on the side of the rotating connecting sleeve away from the carrying plate. The side of the coating liquid tank is fixedly connected to the side of the shell.

[0053] The connecting groove is arranged on the side of the shell, on the side where the rotating connecting sleeve is away from the supporting plate. The connecting groove is connected with the inside of the shell and the inside of the coating liquid tank, and one end of the transverse rotating rod extends through the connecting groove to the inside of the coating liquid tank.

[0054] A plurality of stirring blades are arranged inside the coating liquid tank and sleeved on the transverse rotating rod. The plurality of stirring blades are fixedly connected to the side surface of the transverse rotating rod.

[0055] The liquid outlet valve is arranged on the side of the coating liquid tank, which is located on the side of the coating liquid tank away from the outer shell. One end of the liquid outlet valve passes through the side of the coating liquid tank and is connected to the interior of the coating liquid tank, and the other end passes through the top of the outer shell through a pipe and is connected to the interior of the spray pipe. The liquid outlet valve is also electrically connected to the controller.

[0056] The liquid inlet is arranged at the top of the coating liquid tank and is communicated with the interior of the coating liquid tank.

[0057] When the transverse connecting rod rotates forward, it will drive the stirring blades to rotate. The rotation of the stirring blades can stir the coating liquid inside the coating liquid tank, so as to prevent the coating liquid inside the coating liquid tank from losing its coating performance due to sedimentation.

[0058] When the user starts the spray head through the controller, the controller will automatically control the liquid outlet valve to start. After the liquid outlet valve is started, the liquid inside the coating liquid tank will be input into the spray pipe through the liquid outlet valve and the pipeline, and finally sprayed onto the surface of the lens through the started spray head.

[0059] Furthermore, it also includes: an exhaust fan. The exhaust fan is arranged at the back of the shell and between the carrier plate and the plurality of spray heads. The exhaust fan is connected to the inside of the shell and is also connected to the exhaust gas treatment chamber through a pipeline. The exhaust fan is electrically connected to the controller.

[0060] After spraying the coating liquid on one side of the lens, the user can start the exhaust fan through the controller. After the exhaust fan is started, the exhaust fan can draw the air inside the shell through the pipe to the exhaust gas treatment room, so as to avoid the chemical gas generated by the volatilization of the coating liquid affecting the user's life safety.

[0061] Furthermore, it also includes: a plurality of heaters: the plurality of heaters are respectively arranged inside the shell and are located on both sides of the spray pipe, the plurality of heaters are respectively fixedly connected to the inner top surface of the shell and are electrically connected to the controller.

[0062] After spraying the coating liquid on one side of the lens, the user can start a number of heaters through the controller. After the heaters are started, the temperature inside the housing can be increased to accelerate the evaporation rate of the coating liquid.

[0063] Furthermore, the adjustable clamping mechanism is an arc-shaped clamping mechanism, and a high-friction elastic cushion is arranged inside the arc-shaped surface inside the adjustable clamping mechanism.

[0064] The high-friction elastic soft pad can be provided to prevent the adjustable clamping mechanism from damaging the lens when clamping and fixing the lens.

[0065] Furthermore, the stirring blade is made of corrosion-resistant material.

[0066] The use of corrosion-resistant materials for the stirring blades can prevent the stirring blades from being corroded after being in the coating solution for a long time, thereby reducing the service life of the stirring blades.

[0067] A precision lens, the shape of the precision lens is round or square.

[0068] Beneficial effects of the present invention: 1. The present invention is provided with a lens coating adjustment device, a coating clamping device, a coating liquid storage device, a controller, and a housing. The lens coating adjustment device can adjust the position of the lens and coat the lens, and at the same time drive the coating clamping device to support the lens. When the lens position is adjusted by the lens coating adjustment device, the lens coating adjustment device can also make the coating clamping device rotate the clamped lens, so that the lens can rotate from the coated side to the coated side, waiting for the next coating. When the coating clamping device moves the clamped lens to rotate, the coating clamping device can drive the coating liquid storage device to move, so as to stir the coating liquid to prevent the coating liquid from precipitating and losing its working performance. With such a working setting, when the device coats the lens, the device can adjust the position of the lens, so that lenses of different sizes correspond to spray heads of different sizes, avoiding waste of coating liquid, and can also automatically switch the mirror surface of the lens, and stir the coating liquid before coating to prevent precipitation.

[0069] 2. By setting a one-way clutch, when the lateral rotating rod moves in the opposite direction, it will not drive the gear to reverse, causing the gear to reverse, and the one-way clutch will drive the lateral rotating rod to reverse, thereby driving the lens to rotate again and adjust the mirror surface. This avoids the problem of the lens rotating again when the position of the lens is changed again after the adjustment of the uncoated surface of the lens is completed.

DETAILED DESCRIPTION

[0072] The concept and technical effects of the present invention will be clearly and completely described below in conjunction with embodiments to fully understand the purpose, features and effects of the present invention.

[0073] See also Figure 1-2 : A precision lens and its coating device, including: a lens coating adjustment device, a coating clamping device, a coating liquid storage device, a controller, and a shell 1.

[0074] The housing 1 is arranged on the ground. The lens coating adjustment device is arranged inside the housing 1 and is fixedly connected to the inner wall of the housing 1. The coating clamping device is arranged inside the housing 1 and is connected to the inner wall of the housing 1 and the lens coating adjustment device. The coating liquid storage device is arranged on the side of the housing 1 and is connected to the housing 1 and the coating clamping device. The controller is arranged on the side of the housing 1 and is arranged on the ground, and the controller is electrically connected to the lens coating adjustment device, the coating clamping device, and the coating liquid storage device.

[0075] When the user wants to coat the lens, the user first opens the housing 1, and then places the lens on the lens coating adjustment device. Then, the user starts the lens coating adjustment device through the controller. When the lens coating adjustment device is started, the lens coating adjustment device moves to adjust the position of the lens so that the lens can be under the coating liquid nozzle of a suitable size. When the lens coating adjustment device drives the lens to move, the lens coating adjustment device drives the coating liquid storage device through the coating clamping device to stir the coating liquid, so that the coating liquid will not lose its working performance due to precipitation.

[0076] At the same time, the user can operate the lens coating adjustment device through the controller to stop supporting the lens, thereby driving the coating clamping device to clamp the lens. After clamping is completed, the user can start the lens coating adjustment device again through the controller to coat the clamped lens. After coating is completed, the user can start the lens coating adjustment device again to drive the coating clamping device to stop clamping the lens and drive the lens to rotate, so that the coating liquid dripping on the surface of the lens can be evenly spread on the surface of the lens under the action of centrifugal force and wait for the coating liquid to evaporate.

[0077] After coating one side of the lens, the user can start the lens coating adjustment device through the controller again to drive the coating clamping device to coat the lens again. After coating, the user can control the lens coating adjustment device to adjust the position through the controller, so that the coating clamping device can drive the lens to rotate, so that the lens can rotate from the coated side to the uncoated side. At the same time, the coating clamping device will drive the coating liquid storage device to stir the coating liquid, and then the user can start the lens coating adjustment device through the controller to coat the uncoated side of the lens until the coating liquid is evenly spread and evaporated, so as to complete the coating of the lens.

[0078] With such a working setting, when the device is coating the lens, the device can adjust the position of the lens so that lenses of different sizes correspond to spray heads 202 of different sizes, thereby avoiding waste of coating liquid. At the same time, it can also automatically switch the mirror surface of the lens and stir the coating liquid before coating to prevent precipitation.

[0079] The lens coating adjustment device includes: a rotating and telescopic motor 201, a plurality of spray heads 202, a driving motor, a threaded rod 204, a spray pipe 205, a transverse plate 206, a carrier plate 207, and two rectangular blocks 208.

[0080] The drive motor is arranged at the rear of the shell 1, and its rotating shaft passes through the back of the shell 1 and extends to the inside of the shell 1. The shell of the drive motor is fixedly connected to the back of the shell 1, and the rotating shaft is rotatably connected to the back of the shell 1. The rotating axis is perpendicular to the back of the shell 1, and the drive motor is electrically connected to the controller.

[0081] The two rectangular blocks 208 are respectively arranged inside the shell 1 and are located on both sides of the rotating shaft of the driving motor. The bottom surfaces of the two rectangular blocks 208 are respectively fixedly connected to the inner bottom surface of the shell 1, and the two end surfaces of the two rectangular blocks 208 are respectively fixedly connected to the inner front and back surfaces of the shell 1.

[0082] The threaded rod 204 is horizontally arranged inside the shell 1 and between the two rectangular blocks 208. One end of the threaded rod 204 is fixedly connected to the end face of the rotating shaft of the driving motor, and the other end is rotatably connected to the front face of the shell 1. The rotating axis coincides with the rotating axis of the driving motor.

[0083] The transverse plate 206 is arranged inside the shell 1 and is above the two rectangular blocks 208. The bottom surface of the transverse plate 206 is slidably connected to the top surfaces of the two rectangular blocks 208. The sliding direction is parallel to the axis of the threaded rod 204. A threaded sleeve is provided on the bottom surface of the transverse plate 206, and is sleeved on the threaded rod 204 and threadedly connected to the threaded rod 204. The top surface of the transverse plate 206 is also connected to the coating clamping device.

[0084] The rotary telescopic motor 201 is arranged inside the housing 1 and above the transverse plate 206. The bottom surface of the rotary telescopic motor 201 is fixedly connected to the top surface of the transverse plate 206 and is electrically connected to the controller.

[0085] The carrier plate 207 is arranged inside the outer shell 1 and above the rotating and telescopic motor 201. The bottom surface of the carrier plate 207 is fixedly connected to the end surface of the telescopic rotating shaft of the rotating and telescopic motor 201. A suction cup is arranged on the top surface of the carrier plate 207, and the adsorption surface of the suction cup faces the inner top surface of the outer shell 1, and is connected to the vacuum machine through an air pipe. The vacuum machine is electrically connected to the controller, and the carrier plate 207 is also connected to the coating clamping device.

[0086] The spray pipe 205 is arranged inside the shell 1 and above the carrier plate 207. The spray pipe 205 is fixedly connected to the inner top surface of the shell 1 and is connected to the inside of the coating liquid storage device through a pipeline penetrating the side wall of the shell 1.

[0087] The plurality of spray heads 202 are respectively arranged inside the housing 1 and are respectively located between the spray pipe 205 and the carrier plate 207. The plurality of spray heads 202 are respectively arranged equidistantly below the spray pipe 205 and respectively penetrate the side walls of the spray pipe 205 and are connected with the interior of the spray pipe 205. The plurality of spray heads 202 are also respectively electrically connected to the controller, and the plurality of spray heads 202 are of different sizes.

[0088] When the user wants to coat the lens, the user first places the lens on the carrier plate 207, and then the user starts the retraction of the rotating telescopic motor 201 through the controller. When the rotating telescopic motor 201 retracts, it drives the carrier plate 207 to descend, and the descent of the carrier plate 207 drives the coating clamping device to clamp the lens. When the coating clamping device completes the clamping of the lens, the user can control the driving motor to rotate forward through the controller. After the driving motor rotates forward, the driving motor drives the threaded rod 204 to rotate forward, and the threaded rod 204 drives the transverse plate 206 to move forward. The forward movement of the transverse plate 206 drives the rotating telescopic motor 201, the carrier plate 207, the coating clamping device, and the lens to move forward together and drive the coating clamping device to rotate until the lens moves to the bottom of the spray head 202 that matches the size of the lens. When the coating clamping device rotates, the coating clamping device drives the lens to rotate. When the lens is under the corresponding spray head 202, the user activates the spray head 202 corresponding to the lens again through the controller. After the corresponding spray head 202 is activated, the spray head 202 can spray the coating liquid inside the spray tube 205 onto the mirror surface of the lens below it.

[0089] After the coating liquid is sprayed, the user can control the rotating and telescopic motor 201 to start extending through the controller. The extending of the rotating and telescopic motor 201 drives the carrying plate 207 to rise. The rising of the carrying plate 207 drives the coating clamping device to stop clamping the lens and makes the lens fall on the carrying plate 207. Then, the user starts the vacuum machine through the controller to adsorb the lens on the carrying plate 207, and starts the rotating and telescopic motor 201 to rotate. The rotation of the rotating and telescopic motor 201 drives the carrying plate 207 to rotate. The rotation of the carrying plate 207 drives the lens to rotate and drives the lens clamping device to move. The coating liquid on the surface of the lens will be evenly spread on the surface of the lens under the action of centrifugal force, so as to complete the uniform coating of the coating liquid and accelerate the evaporation.

[0090] When one side of the lens is coated, the user can stop the vacuum machine through the controller and start the retracting of the rotating telescopic motor 201. The vacuum machine stops working and the carrier plate 207 stops adsorbing the lens. The retraction of the rotating telescopic motor 201 drives the carrier plate 207 to descend. The descent of the carrier plate 207 drives the coating clamping device to clamp the lens. When the coating clamping device completes clamping the lens, the user can control the driving motor to start forward rotation through the controller again. The forward rotation of the driving motor drives the threaded rod 204 to rotate forward. The forward rotation of the threaded rod 204 drives the transverse plate 206 to move forward. The forward movement of the transverse plate 206 drives the rotating telescopic motor 201, the carrier plate 207, the coating clamping device, and the lens together. The coating clamping device moves forward and drives the coating clamping device to rotate. When the coating clamping device moves forward, it drives the clamped lens to move forward and rotate together until the other uncoated surface of the clamped lens faces the matching spray head 202. Then the user controls the driving motor to reverse through the controller. The driving motor reverses and drives the threaded rod 204 to reverse. The threaded rod 204 reverses and drives the transverse plate 206 to move in the opposite direction. The transverse plate 206 moves in the opposite direction and drives the rotating telescopic motor 201, the coating clamping device, and the lens to move in the opposite direction, but does not drive the coating clamping device to rotate. In this way, the lens that has completed the mirror switching can be moved again to the bottom of the matching spray head 202, so as to complete the function of switching the uncoated lens of the lens. Then the user can start the rotating telescopic motor 201 and the matching spray head 202 through the controller again to complete the function of coating the uncoated surface of the lens.

[0103] Two adjustable clamping mechanisms 304 are respectively arranged inside the shell 1 and are respectively located above the supporting plate 207. One of the adjustable clamping mechanisms 304 is rotatably connected to the side of the moving block 303 close to the supporting plate 207, and the rotation axis is perpendicular to the axis of the rotating telescopic motor 201. The other adjustable clamping mechanism 304 is connected to the adjusting rotation mechanism. The two adjustable clamping mechanisms 304 are in the same straight line and are electrically connected to the controller respectively.

[0104] When the carrying plate 207 descends, the carrying plate 207 descends, driving the driving rod 307 to descend, and the driving rod 307 descends, driving the sliding pin 308 to descend in the two elliptical rings 306, and the sliding pin 308 descends, driving the connecting rod 310 to descend, and the connecting rod 310 descends, pulling the moving block 303 to move toward the direction close to the carrying plate 207, and the movement of the moving block 303 drives one of the adjustable clamping mechanisms 304 to move, and stops applying pressure to the reset spring 302, so that the reset spring 302 can recover, and at the same time, one of the adjustable clamping mechanisms 304 moves to drive the lens to contact with the other adjustable clamping mechanism 304, until the carrying plate 207 descends to the lowest point driven by the rotating telescopic motor 201, and the two adjustable clamping mechanisms 304 can firmly fix the lens.

[0105] When the carrying plate 207 rises, the carrying plate 207 rises, driving the driving rod 307 to rise, and the driving rod 307 rises and drives the sliding pin 308 to rise in the two elliptical rings 306. The sliding pin 308 rises and drives the connecting rod 310 to rise. The connecting rod 310 rises and pulls the moving block 303 to move away from the carrying plate 207. The movement of the moving block 303 drives one of the adjustable clamping mechanisms 304 to move, and exerts pressure on the reset spring 302, so that the reset spring 302 can be shortened. At the same time, the movement of one of the adjustable clamping mechanisms 304 will stop exerting pressure on the lens to contact the other adjustable clamping mechanism 304, and the lens will fall on the carrying plate 207 again until the carrying plate 207 rises to the highest point driven by the rotating telescopic motor 201, and one of the adjustable clamping mechanisms 304 can return to its original position.

[0106] When the carrier plate 207 rotates, the carrier plate 207 drives the lens to rotate, and drives the sliding block to slide in the sliding groove 309. When the sliding block slides in the sliding groove 309, the sliding block can always maintain its current position relative to the driving rod 307 in the sliding groove 309.

[0107] The user can control the size of the adjustable clamping mechanism 304 through the controller to accommodate lenses of different radius sizes.

[0108] When the horizontal plate 206 moves forward, the horizontal plate 206 moves forward, driving the vertical plate 301, the vertical bearing rod 305, and the other adjustable clamping mechanism 304 to move forward, and at the same time, by rotating the telescopic motor 201 and the bearing plate 207, the driving rod 307, the sliding block, the sliding pin 308, the two elliptical rings 306, the connecting rod 310, the moving block 303, the reset spring 302, and the adjusting rotation mechanism to move forward, so that the two adjustable clamping mechanisms 304 can drive the clamped lenses to move forward. At the same time, when the adjusting rotation mechanism moves forward, the adjusting rotation mechanism can drive the other adjustable clamping mechanism 304 to rotate forward, so that one of the adjustable clamping mechanisms 304 can be rotated through the lens, so that the lens can be rotated from the coated side to the uncoated side.

[0109] When the horizontal plate 206 moves in the reverse direction, the horizontal plate 206 moves in the forward direction, driving the vertical plate 301, the vertical bearing rod 305, and the other adjustable clamping mechanism 304 to move in the reverse direction, and at the same time, by rotating the telescopic motor 201 and the bearing plate 207, the driving rod 307, the sliding block, the sliding pin 308, the two elliptical rings 306, the connecting rod 310, the moving block 303, the reset spring 302, and the adjusting and rotating mechanism move in the reverse direction, so that the two adjustable clamping mechanisms 304 can drive the clamped lenses to move in the reverse direction. At the same time, when the adjusting and rotating mechanism moves in the reverse direction, the adjusting and rotating mechanism can drive the other adjustable clamping mechanism 304 to rotate in the reverse direction, and the adjustable clamping mechanism 304 will not drive the other adjustable clamping mechanism 304 to rotate when moving in the reverse direction.

[0117] When the vertical bearing rod 305 moves forward, the forward movement of the vertical bearing rod 305 drives the rotating connecting sleeve 402 to move forward, the forward movement of the rotating connecting sleeve 402 drives the transverse rotating rod 401 to move forward, the transverse rotating rod 401 drives another adjustable clamping mechanism 304 to move forward, and drives the one-way clutch 403 to move forward, the one-way clutch 403 drives the gear 404 to move forward, and the gear 404 will rotate forward along the rack 406 when moving forward, the gear 404 drives the one-way clutch 403 to rotate forward, the one-way clutch 403 drives the transverse rotating rod 401 to rotate forward, the transverse rotating rod 401 drives another adjustable clamping mechanism 304 to rotate, and drives the coating liquid storage device to move. In this way, the coated surface of the lens is adjusted to the uncoated surface.

[0118] When the vertical bearing rod 305 moves in the reverse direction, the reverse movement of the vertical bearing rod 305 drives the rotating connecting sleeve 402 to move in the reverse direction, the reverse movement of the rotating connecting sleeve 402 drives the transverse rotating rod 401 to move in the reverse direction, the reverse movement of the transverse rotating rod 401 drives another adjustable clamping mechanism 304 to move in the reverse direction, and at the same time drives the one-way clutch 403 to move in the reverse direction, the reverse movement of the one-way clutch 403 drives the gear 404 to move in the reverse direction, and the gear 404 will rotate in the reverse direction along the rack 406 when moving in the reverse direction, and the reverse rotation of the gear 404 will not drive the one-way clutch 403 to rotate, so as to avoid that after the lens is adjusted to the uncoated surface, the lens is rotated again when the position of the lens is adjusted to adjust to the coated surface.

[0119] The coating liquid storage device comprises: a communication tank 501 , a coating liquid tank 502 , a plurality of stirring blades 503 , a liquid outlet valve 504 , and a liquid inlet 505 .

[0120] The coating liquid tank 502 is disposed on the side of the housing 1 and is located on the side of the rotating connecting sleeve 402 away from the supporting plate 207 . The side of the coating liquid tank 502 is fixedly connected to the side of the housing 1 .

[0121] The connecting groove 501 is arranged on the side of the shell 1, on the side of the rotating connecting sleeve 402 away from the supporting plate 207. The connecting groove 501 is connected with the inside of the shell 1 and the inside of the coating liquid tank 502, and one end of the transverse rotating rod 401 passes through the connecting groove 501 and extends to the inside of the coating liquid tank 502.

[0122] A plurality of stirring blades 503 are disposed inside the coating liquid tank 502 and sleeved on the transverse rotating rod 401 . The plurality of stirring blades 503 are fixedly connected to the side surface of the transverse rotating rod 401 .

[0123] The liquid outlet valve 504 is arranged on the side of the coating liquid tank 502, which is located on the side of the coating liquid tank 502 away from the outer shell 1. One end of the liquid outlet valve 504 passes through the side of the coating liquid tank 502 and is connected to the interior of the coating liquid tank 502, and the other end passes through the top of the outer shell 1 through a pipeline and is connected to the interior of the spray pipe 205. The liquid outlet valve 504 is also electrically connected to the controller.

[0124] The liquid inlet 505 is disposed at the top of the coating liquid tank 502 and is communicated with the interior of the coating liquid tank 502 .

[0125] When the transverse connecting rod 310 rotates forward, the forward rotation of the transverse connecting rod 310 will drive the plurality of stirring blades 503 to rotate. The rotation of the plurality of stirring blades 503 can stir the coating liquid inside the coating liquid tank 502, so as to prevent the coating liquid inside the coating liquid tank 502 from losing its coating performance due to sedimentation.

[0126] When the user starts the spray head 202 through the controller, the controller will automatically control the liquid outlet valve 504 to start. After the liquid outlet valve 504 is started, the liquid inside the coating liquid tank 502 will be input into the spray pipe 205 through the liquid outlet valve 504 and the pipeline, and finally sprayed onto the surface of the lens through the started spray head 202.

[0127] It also includes: an exhaust fan 6. The exhaust fan 6 is arranged at the back of the housing 1 and between the carrier plate 207 and the plurality of spray heads 202. The exhaust fan 6 is connected to the interior of the housing 1 and is also connected to the exhaust gas treatment chamber through a pipeline. The exhaust fan 6 is electrically connected to the controller.

[0128] After spraying the coating liquid on one side of the lens, the user can start the exhaust fan 6 through the controller. After the exhaust fan 6 is started, the exhaust fan 6 can extract the air inside the shell 1 through the pipe to the exhaust gas treatment room, so as to avoid the chemical gas generated after the coating liquid evaporates and affect the user's life safety.

[0129] It also includes: a plurality of heaters 7: the plurality of heaters 7 are respectively arranged inside the shell 1 and are located on both sides of the spray pipe 205.

[0132] The high-friction elastic cushion can be provided to prevent the adjustable clamping mechanism 304 from damaging the lens when clamping and fixing the lens.

[0133] The stirring blade 503 is made of corrosion-resistant material.

[0134] The stirring blade 503 is made of corrosion-resistant material to prevent the stirring blade 503 from being corroded after being in the coating solution for a long time, thereby reducing the service life of the stirring blade 503 .

[0135] A precision lens, the shape of the precision lens is round or square.

[0136] Working process: When the user wants to coat the lens, the user first places the lens on the carrier plate 207 and adjusts the clamping range of the two adjustable clamping mechanisms 304 through the controller so that the clamping range of the adjustable clamping mechanisms 304 can match the current lens shape and size. Then at this time, the user starts the retraction of the rotating and telescopic motor 201 through the controller. When the rotating and telescopic motor 201 retracts, it drives the carrying plate 207 to descend. The descent of the carrying plate 207 drives the driving rod 307 to descend. The descent of the driving rod 307 drives the sliding pin 308 to descend in the two elliptical rings 306. The descent of the sliding pin 308 drives the connecting rod 310 to descend. The descent of the connecting rod 310 pulls the moving block 303 to move toward the direction close to the carrying plate 207. The movement of the moving block 303 drives one of the adjustable clamping mechanisms 304 to move, and stops applying pressure to the reset spring 302, so that the reset spring 302 can recover. At the same time, one of the adjustable clamping mechanisms 304 moves to contact the lens and drives the lens to contact the other adjustable clamping mechanism 304, until the carrying plate 207 drops to the lowest point driven by the rotating and telescopic motor 201, and the two adjustable clamping mechanisms 304 can firmly fix the lens.

[0137] When the lens is clamped and fixed, the user can control the driving motor to rotate forward through the controller. After the driving motor rotates forward, the driving motor rotates forward to drive the threaded rod 204 to rotate forward, and the threaded rod 204 rotates forward to drive the horizontal plate 206 to move forward. The horizontal plate 206 moves forward to drive the rotating telescopic motor 201, the vertical plate 301, and the vertical bearing rod 305 to move forward together. The rotating telescopic motor 201 moves forward to drive the bearing plate 207 to move forward, and the bearing plate 207 moves forward to drive the sliding block to move forward. The positive movement of the block drives the driving rod 307 to move forward, the positive movement of the driving rod 307 drives the sliding pin 308 to move forward, the positive movement of the sliding pin 308 drives the two elliptical rings 306 to move forward, and drives the connecting rod 310 to move forward, the positive movement of the connecting rod 310 drives the moving block 303 to move forward, the positive movement of the moving block 303 drives the return spring 302 to move forward and drives one of the adjustable clamping mechanisms 304 to move forward, and the positive movement of one of the adjustable clamping mechanisms 304 drives the lens to move forward.

[0138] When the vertical plate 301 moves forward, the forward movement of the vertical plate 301 will also drive the return spring 302 to move forward, thereby driving the moving block 303 to move one of the adjustable clamping mechanisms 304 to move forward, thereby driving the lens to move forward.

[0139] When the vertical bearing rod 305 moves forward, the vertical bearing rod 305 moves forward and drives the rotating connecting sleeve 402 to move forward, the rotating connecting sleeve 402 moves forward and drives the transverse rotating rod 401 to move forward, the transverse rotating rod 401 moves forward and drives another adjustable clamping mechanism 304 to move forward, and drives the one-way clutch 403 to move forward. The other adjustable clamping mechanism 304 moves forward and drives the clamped lens to move forward, so that the two adjustable clamping mechanisms 304 drive the lens to move forward and adjust the position to the bottom of the matching spray head 202.

[0140] When the one-way clutch 403 moves forward, the one-way clutch 403 moves forward and drives the gear 404 to move forward. When the gear 404 moves forward, it will rotate forward along the rack 406. The gear 404 moves forward and rotates to drive the one-way clutch 403 to move and rotate forward. The one-way clutch 403 moves and rotates forward to drive the transverse rotation rod 401 to rotate forward. The transverse rotation rod 401 moves and rotates forward to drive another adjustable clamping mechanism 304 to move and rotate, and drives a plurality of stirring blades 503 to move and rotate. When the other adjustable clamping mechanism 304 rotates, it can drive the lens to move and rotate forward. The movement and rotation of the lens can drive one of the adjustable clamping mechanisms 304 to move and rotate forward, so that the lens can be rotated to the required mirror surface while moving. The rotation of the plurality of stirring blades 503 can stir the coating liquid inside the coating liquid tank 502 to prevent the coating liquid from settling, thereby causing the coating liquid to lose its working performance.

[0141] When the lens is under the matching spray head 202, the user can start the matching spray head 202 through the controller. After the matching spray head 202 is started, the controller will also control the liquid outlet valve 504 to start. After the liquid outlet valve 504 is started, the coating liquid inside the coating liquid tank 502 will be transported to the inside of the spray pipe 205 through the liquid outlet valve 504 and the pipeline. When the spray head 202 is started, the spray head 202 can spray the coating liquid onto the surface of the lens directly below it.

[0142] When the coating liquid is sprayed on the surface of the lens, the user can control the rotating and telescopic motor 201 to start extending through the controller. The rotating and telescopic motor 201 extends to drive the carrier plate 207 to rise, and the rising of the carrier plate 207 drives the driving rod 307 to rise. The rising of the driving rod 307 drives the sliding pin 308 to rise in the two elliptical rings 306, and the rising of the sliding pin 308 drives the connecting rod 310 to rise. The rising of the connecting rod 310 drives the moving block 303 to move away from the carrier plate 207. The movement of the moving block 303 drives one of the adjustable clamping mechanisms 304 to move, and applies pressure to the reset spring 302, so that the reset spring 302 can retract again. At the same time, one of the adjustable clamping mechanisms 304 moves to stop applying pressure to the lens, and causes the lens to separate from the other adjustable clamping mechanism 304 and fall on the surface of the carrier plate 207 until the carrier plate 207 drops to the lowest point driven by the rotating and telescopic motor 201.

[0143] When the lens falls on the surface of the carrier plate 207 again, the user starts the vacuum machine through the controller to adsorb the lens on the carrier plate 207, and then starts the rotating telescopic motor 201 to rotate, starts the heaters 7 to heat, and starts the exhaust fan 6 to exhaust air. The rotating telescopic motor 201 rotates to drive the carrier plate 207 to rotate, and the rotation of the carrier plate 207 drives the lens to rotate, and drives the sliding block to slide in the sliding groove 309. When the lens rotates, the coating liquid on the surface of the lens will be evenly spread on the surface of the lens under the action of centrifugal force, so as to complete the uniform coating of the coating liquid and accelerate the evaporation. When the sliding block slides in the sliding groove 309, the sliding block can always maintain the current position relative to the driving rod 307 in the sliding groove 309.

[0144] After being started, the heaters 7 can increase the temperature inside the housing 1, thereby accelerating the evaporation rate of the coating solution.

[0145] After the exhaust fan 6 is started, the exhaust fan 6 can extract the air inside the housing 1 through the pipeline to the exhaust gas treatment chamber, so as to prevent the chemical gas generated after the volatilization of the coating liquid from affecting the life safety of the user.

[0146] When the user has finished coating one side of the lens, the user can use the controller to stop the vacuum machine and control the rotary telescopic motor 201 to start retracting, thereby completing the clamping of the lens and adjusting the lens from the coated side to the uncoated side.

[0147] After the lens is adjusted from the coated side to the uncoated side, the lens is often not out of the matching spray head 202. At this time, the user can start the reverse rotation of the drive motor through the controller. After the drive motor reverses, the reverse rotation of the drive motor drives the threaded rod 204 to reverse, and the reverse rotation of the threaded rod 204 drives the horizontal plate 206 to move in the opposite direction. The reverse movement of the horizontal plate 206 drives the vertical plate 301 and the vertical bearing rod 305 of the rotating telescopic motor 201 to move in the opposite direction. The reverse movement of the rotating telescopic motor 201 drives the bearing plate 207 to move in the opposite direction. The bearing plate 207 moves in the opposite direction. The movement drives the sliding block to move in the opposite direction, the opposite movement of the sliding block drives the driving rod 307 to move in the opposite direction, the opposite movement of the driving rod 307 drives the sliding pin 308 to move in the opposite direction, the opposite movement of the sliding pin 308 drives the two elliptical rings 306 to move in the opposite direction, and drives the connecting rod 310 to move in the opposite direction, the opposite movement of the connecting rod 310 drives the moving block 303 to move in the opposite direction, the opposite movement of the moving block 303 drives the reset spring 302 to move in the opposite direction and drives one of the adjustable clamping mechanisms 304 to move in the opposite direction, and the opposite movement of one of the adjustable clamping mechanisms 304 drives the lens to move in the opposite direction.

[0148] When the vertical bearing rod 305 moves in the reverse direction, the reverse movement of the vertical bearing rod 305 drives the rotating connecting sleeve 402 to move in the reverse direction, the reverse movement of the rotating connecting sleeve 402 drives the lateral rotating rod 401 to move in the reverse direction, and the reverse movement of the lateral rotating rod 401 drives another adjustable clamping mechanism 304 to move in the reverse direction, and drives the one-way clutch 403 and a plurality of stirring blades 503 to move in the reverse direction at the same time. The reverse movement of another adjustable clamping mechanism 304 drives the lens to move in the reverse direction, so that the two adjustable clamping mechanisms 304 drive the lens to move in the reverse direction and adjust the position to the bottom of the matching spray head 202.

[0149] When the one-way clutch 403 moves in the reverse direction, the one-way clutch 403 moves in the reverse direction and drives the gear 404 to move in the reverse direction. When the gear 404 moves in the reverse direction, it rotates in the reverse direction along the rack 406. The reverse rotation of the gear 404 drives the one-way clutch 403 to reverse. The reverse rotation of the one-way clutch 403 will not drive the lateral rotation rod 401 to rotate, so as to avoid adjusting the lens so that the uncoated surface faces the spray head 202, and then driving the lens to the bottom of the matching spray head 202, causing the lens to rotate again, so that the coated rotation of the uncoated surface of the lens does not face the matching spray head 202.

[0150] Then the user once again starts the spray head 202, the rotating and telescopic motor 201, the vacuum machine, the driving motor, the heaters 7, and the exhaust fan 6 through the controller to complete the work of coating and collecting the uncoated surface of the lens.

[0151] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall all fall within the scope of protection of the present invention.
