Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, specifically to a diaphragm peeling structure for lens processing. Background Technology

[0002] With the rapid development and application of technologies such as virtual reality and augmented reality, head-mounted display devices based on these two technologies have gradually appeared in the public eye. The optical engine inside this head-mounted display device emits light, which is refracted by lenses and uses projection principles and waveguide technology to achieve near-eye display, providing people with 3D display technology. To achieve the reflection of the light path, special films, such as absorptive polarizers, reflective polarizers, and quarter-wave plates, need to be attached to the surfaces of both sides of the lens. However, when the lens is reprocessed, the surface films need to be peeled off.

[0003] According to Chinese Patent Publication No. CN220681873U, a diaphragm peeling structure for lens processing is disclosed. This structure involves installing a peeling component that can translate and extend / retract forward and backward at the front end of a lens after it has been positioned. The peeling component automatically peels off the diaphragm. When the peeling component moves, it abuts against the side of the lens, automatically triggering a control switch. This causes an electric push rod to move the peeling component inward, allowing it to insert into the middle of the lens and the diaphragm. Simultaneously, an electromagnet and a magnetic sheet magnetically attract and clamp the diaphragm apart. This structure is simple and convenient to operate, has a fast diaphragm peeling speed, improves the practicality of the diaphragm peeling structure, and reduces labor costs.

[0004] However, this technical solution can only remove a lens after the diaphragm has been peeled off, reattach a new lens to be peeled off, and then perform the peeling operation again. This results in a long downtime for the equipment, which greatly affects the efficiency of lens peeling. Therefore, we propose a diaphragm peeling structure for lens processing. Utility Model Content

[0005] The purpose of this invention is to provide a diaphragm peeling structure for lens processing, which solves the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a diaphragm peeling structure for lens processing, comprising a base, a support platform, an electric chuck, and a peeling assembly. The base has an organic groove at its top, in which a motor is fixedly installed. The support platform is driven by the motor. The support platform has a second organic groove near its edge at its top, in which a second motor is fixedly installed. The electric chuck is driven by the motor. A fixing frame is fixedly installed at the top of the base, and a fixing frame is fixedly installed at its top. A motor is fixedly installed on the front of the fixing frame. A fixing block is slidably connected to the inner wall of the fixing frame and is driven by the motor. An electric push rod is fixedly installed at the bottom of the fixing block. The peeling assembly is fixedly installed at the bottom of the electric push rod. A contact switch is provided below the second motor and fixedly installed at the bottom of the support platform. A stop block is fixedly installed at the top of the base. A controller is fixedly installed at the center of the top of the support platform.

[0007] Preferably, the number of the second slot, the electric chuck, and the contact switch are all four. A second fixed frame is provided between the first fixed frame and the support platform. The second fixed frame is fixedly installed on the top of the base. A heater is fixedly installed on the top of the inner wall of the second fixed frame. By setting the heater, the diaphragm on the lens can be heated, causing the diaphragm to curl up, thereby facilitating peeling.

[0008] Preferably, the contact switch is signal-connected to the controller, and the controller is electrically connected to motor one, motor two, motor three, electric chuck, heater, and electric push rod.

[0009] Preferably, a rotating shaft is fixedly installed at the output end of the first motor, the support platform is fixedly installed at the top of the rotating shaft, a rotating shaft is fixedly installed at the output end of the second motor, and the electric chuck is fixedly installed at the top of the rotating shaft. By setting the rotating shaft, the first motor can drive the support platform to rotate through the rotating shaft. By setting the rotating shaft, the second motor can drive the electric chuck to rotate through the rotating shaft.

[0010] Preferably, a screw is fixedly installed at the output end of the motor three. The screw passes through the front of the fixed frame and is rotatably connected to the fixed frame through a bearing seat. The fixed block is threaded onto the outer wall of the screw. By setting the screw, the motor three can drive the fixed block to move back and forth through the screw.

[0011] Preferably, a limiting slide plate is fixedly installed on the outer wall of the fixing block, and a limiting groove is formed on the inner wall of the fixing frame. The limiting slide plate and the limiting groove are slidably connected. By setting the limiting slide plate and the limiting groove, the fixing block can be limited, thereby improving the stability of the fixing block when moving and ensuring the stability of the peeling component during the peeling operation.

[0012] This invention provides a diaphragm peeling structure for lens processing. This diaphragm peeling structure for lens processing has the following beneficial effects:

[0013] (1) The lens processing film peeling structure is equipped with multiple sets of electric chucks, which can rotate to peel the lens film on the electric chucks. During the lens film peeling process of one set of electric chucks, another set of peeled lenses can be disassembled at the same time and a new lens to be peeled can be re-clamped, which greatly saves the time spent on loading and unloading lenses and improves the lens peeling efficiency. It solves the problem that in the existing technical solution, only after the lens film is peeled, it can be disassembled, a new lens to be peeled can be re-fixed, and then the peeling operation can be performed, which results in a long downtime of the equipment and thus greatly affects the efficiency of lens peeling.

[0014] (2) The diaphragm peeling structure of the lens processing can limit the fixed block by setting a limiting slide plate and a limiting slide groove, thereby improving the stability of the fixed block when moving, thus ensuring the stability of the peeling component during the peeling operation. The structure is simple and practical. Attached Figure Description

[0024] like Figure 1-5 As shown, this utility model provides a technical solution: a diaphragm peeling structure for lens processing, including a base 1, a support platform 2, an electric chuck 9, and a peeling assembly 18. An organic groove 3 is formed at the top of the base 1, and a motor 4 is fixedly installed in the groove 3. The support platform 2 is drivenly connected to the motor 4.

A fixing frame 12 is fixedly installed at the top of the base 1. A fixed frame 13 is fixedly installed at one end, a motor 14 is fixedly installed on the front of the fixed frame 13, a fixed block 16 is slidably connected to the inner wall of the fixed frame 13, the fixed block 16 is connected to the motor 14 through transmission, an electric push rod 17 is fixedly installed at the bottom of the fixed block 16, a peeling component 18 is fixedly installed at the bottom of the electric push rod 17, a contact switch 10 is provided below the motor 7, the contact switch 10 is fixedly installed at the bottom of the support platform 2, a stop block 11 is fixedly installed at the top of the base 1, and a controller 23 is fixedly installed at the center of the top of the support platform 2.

[0025] Furthermore, there are four machine slots 6, four electric chucks 9 and four contact switches 10. A second fixed frame 21 is provided between the first fixed frame 12 and the support platform 2. The second fixed frame 21 is fixedly installed on the top of the base 1. A heater 22 is fixedly installed on the top of the inner wall of the second fixed frame 21.

[0026] The heater 22 can be used to heat the diaphragm on the lens, causing the diaphragm to curl up at the edges, thus making it easier to peel off.

[0027] Furthermore, the contact switch 10 is signal-connected to the controller 23, and the controller 23 is electrically connected to the motor 4, motor 7, motor 14, electric chuck 9, heater 22, and electric push rod 17.

[0028] Furthermore, a rotating shaft 5 is fixedly installed at the output end of motor 4, a support platform 2 is fixedly installed at the top of rotating shaft 5, a rotating shaft 8 is fixedly installed at the output end of motor 7, and an electric chuck 9 is fixedly installed at the top of rotating shaft 8.

[0029] Specifically, by setting a rotating shaft 5, motor 4 can drive the support platform 2 to rotate through the rotating shaft 5, and by setting a rotating shaft 8, motor 7 can drive the electric chuck 9 to rotate through the rotating shaft 8.

[0030] Furthermore, a screw 15 is fixedly installed at the output end of the motor 3 14. The screw 15 passes through the front of the fixed frame 13, and the screw 15 is rotatably connected to the fixed frame 13 through the bearing seat. The fixing block 16 is threaded onto the outer wall of the screw 15.

[0031] Among them, by setting the screw 15, the motor 14 can drive the fixed block 16 to move back and forth through the screw 15.

[0032] Furthermore, a limiting slide plate 19 is fixedly installed on the outer wall of the fixing block 16, and a limiting slide groove 20 is opened on the inner wall of the fixing frame 13, and the limiting slide plate 19 and the limiting slide groove 20 are slidably connected.

[0033] By setting the limiting slide plate 19 and the limiting slide groove 20, the fixing block 16 can be limited, improving the stability of the fixing block 16 when moving, thereby ensuring the stability of the peeling component 18 during the peeling operation.

[0034] The peeling component 18 is the technology disclosed in the diaphragm peeling structure of lens processing, with the publication number CN220681873U. Therefore, it is not described or drawn in detail in this document and the accompanying drawings. Those skilled in the art can easily adapt it to this solution based on the above document.

[0035] Specifically, in the above technical solution, when using the lens processing film peeling structure, the lens whose film needs to be peeled is placed on the electric chuck 9, and the lens is clamped and fixed by the electric chuck 9. Then, the controller 23 starts the first motor 4, which drives the support platform 2 to rotate through the first shaft 5. The support platform 2 then drives the electric chuck 9 to move below the heater 22 through the second motor 7 and the second shaft 8. The contact switch 10 below the second motor 7 contacts the stop block 11. The contact switch 10 sends a signal to the controller 23, causing the controller 23 to start the second motor 7, so that the second motor... 7. The rotating shaft 8 drives the electric chuck 9 to rotate, which in turn drives the lens to rotate. The heater 22 heats the edge of the diaphragm on the lens, causing the edge of the diaphragm to curl up. Then, the electric push rod 17 is activated, causing it to move the peeling assembly 18 to the height corresponding to the diaphragm on the lens. Then, the controller 23 activates the motor 14, which drives the screw 15 to rotate. The screw 15 drives the moving block to move backward. The moving block, through the electric push rod 17, drives the peeling assembly 18 to move backward, causing the peeling assembly 18 to peel the diaphragm off the lens. After the lens film on one electric chuck 9 is peeled off, the controller 23 controls the motor 14 to reverse, causing the peeling assembly 18 to move forward to its original position. Then, the controller 23 controls the motor 4 to start again, causing the support platform 2 to rotate 90°, so that the lens with the film to be peeled on the next electric chuck 9 moves to below the heater 22, and the above peeling steps are repeated. At the same time, the personnel can remove the peeled lens from the electric chuck 9 and install a new lens with the film to be peeled, saving the time spent on loading and unloading lenses. Through the above structure, multiple sets of electric chucks 9 are set up, which can rotate... The rotating chuck 9 performs a lens diaphragm peeling operation. During the lens diaphragm peeling process of one set of electric chuck 9, another set of peeled lenses can be disassembled and re-clamped with a new lens to be peeled. This greatly saves the time spent on loading and unloading lenses, improves the lens peeling efficiency, and solves the problem in the existing technology where a lens diaphragm can only be peeled, then disassembled, re-fixed with a new lens to be peeled, and then peeled again, resulting in long equipment downtime and greatly affecting the lens peeling efficiency.

[0036] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art.
