Abstract
Description
Technical Field
[0001] This utility model relates to the field of lens clamping technology, specifically to an automatic lens clamping device. Background Technology
[0002] Optical lenses are currently primarily made from resin. In the manufacturing process of optical lenses, the lens needs to be placed in a fixture, such as... Figure 1 As shown, this is a combination clamp structure, with three clamping points clamping against the outer periphery of the lens. The clamp drives the lens to perform subsequent cleaning and processing operations.
[0003] In existing technologies, most methods involve manually opening the clamps or using two sets of grippers to move in opposite directions to open the clamps.
[0004] Due to the structural characteristics of the three clamping points of the fixture, the method of using two sets of clamping hands to support the clamp can easily cause the lens to be clamped only between the two lateral clamping points, without contacting the top clamping point. This can cause the lens to fall off the fixture during transportation or subsequent cleaning and processing operations. While manually opening the fixture can ensure that all three clamping points are against the outer periphery of the lens, the heads of the clamping points are relatively sharp, which can easily scratch the workers, increasing the risk of injury to employees, and the clamping efficiency is low. Utility Model Content
[0005] In view of this, the problem to be solved by this utility model is to provide an automatic lens clamping device.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] An automatic lens clamping device includes a clamping base, a lens lifting platform assembly located in front of the clamping base, and a rotating roller assembly located laterally in front of the clamping base.
[0008] The clamp holder is equipped with a right support leg and a left support leg, which can reciprocate along the Y direction of the clamp holder to open the clamp.
[0009] The roller assembly is mounted on a reciprocating drive, which drives the roller assembly to reciprocate along the X direction of the clamp holder and thus abut against the edge of the lens.
[0010] The rotating rollers in the roller assembly are used to drive the lens to rotate along one side of the clamp towards the clamping point and towards the top clamping point.
[0011] The clamp holder is provided with an independent limiting mechanism on its side. The independent limiting mechanism can reciprocate along the vertical direction of the clamp holder to abut against the supporting clamp.
[0012] A right short-leg limiting arm is also provided on the right side of the clamp holder, which can rotate towards or away from the clamp holder to prevent the clamp from tilting upwards. A left short-leg limiting arm is also provided on the left side of the clamp holder, which can move vertically to prevent the clamp from tilting upwards. A front long-leg limiting arm is also provided on the left side of the clamp holder, which can move vertically to prevent the clamp from tilting upwards.
[0013] The lens lifting platform assembly includes a base and a movable platform for carrying the lens. The output end of the lifter passes through the base and is fixedly connected to the movable platform.
[0014] The roller assembly also includes a motor. The output end of the reciprocating driver is connected to an extension frame. The motor is vertically mounted on the extension frame, and the output end of the motor passes through the extension frame and is connected to the roller.
[0015] The roller assembly and the drive unit I are also mounted on the moving platform.
[0016] The automatic lens clamping device also includes a long-leg movement positioning sensor, which is located in front of the lens lifting platform assembly.
[0017] The advantages and positive effects of this utility model are:
[0018] Through the structural design of fixture holder, lens lifting platform assembly, and rotating roller assembly, the lens can rotate from the left side of the fixture towards the top clamping point, and the return stroke of the support leg causes the right side to retract towards the clamping point to clamp the edge of the lens. This achieves the joint clamping of the lens edge by three clamping points, preventing the lens from falling off the fixture during transportation or subsequent cleaning and processing operations, and also resulting in high clamping efficiency.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] like Figures 1 to 4 As shown, an automatic lens clamping device includes a clamping base 2, a lens lifting platform assembly 8 constructed in front of the clamping base 2, and a rotating roller assembly 3 constructed laterally in front of the clamping base 2.
[0031] The shape of the clamp holder 2 is adapted to the clamp 1. It has two sets of clamping platforms 22 symmetrically arranged in the Y direction. The clamp holder 2 is provided with a left support leg 21 and a right support leg 23. The left support leg 21 and the right support leg 23 can move back and forth along the Y direction of the clamp holder 2. The support leg continuously applies pressure to the inside of the clamp 1, and the clamping platform 22 abuts against the outside of the clamp 1, thereby cooperating with the support leg to open the clamp 1 in the X direction.
[0032] The lens lifting platform 8 is used to drive the lens upward so that it enters the range of the spread clamp 1. At this time, the left support leg 21 moves back, so that the opening angle of the clamp 1 becomes smaller until the two clamping points on the left and right sides of the clamp 1 abut against the edge of the lens.
[0033] The roller assembly 3 is mounted on the reciprocating driver 4. The reciprocating driver 4 drives the roller assembly 3 to reciprocate along the X direction of the clamping seat 2, thereby causing the roller 31 to abut against the edge of the lens. The roller 31 in the roller assembly 3 drives the lens to rotate from the left clamping point to the top clamping point of the clamp through its own rotation. During this process, due to the action of the independent limiting mechanism, the lens contacts the right short leg support point and the independent limiting mechanism. The lens rotates with the independent limiting mechanism as the support point. At the same time, due to the deformation of the clamp itself, the left short leg of the clamp retracts to the right and keeps in contact with the lens. The right clamping point separates from the edge of the lens, thereby realizing the clamping of the lens by the top clamping point and the left clamping point. The long leg of the clamp is then affected by the rotation of the lens and moves along the Y direction. At the same time, the long leg movement sensor 7 detects the displacement of the long leg. After reaching a certain displacement, the sensor outputs a signal to stop the rotation of the lens. The right support foot 23 retracts to the clamping point and clamps the edge of the lens, thereby realizing the joint clamping of the lens edge by the three clamping points.
[0034] Furthermore, considering that during the process of the rotating roller 31 driving the lens to rotate from the left side of the clamping point to the top clamping point of the fixture, the area near the left side clamping point is the main stress area, and the material properties of the clamp 1 are relatively easy to deform, which may cause the lens to fall off when force is applied; therefore, this mechanism is equipped with an independent limiting mechanism 5. The independent limiting mechanism 5 is a movable column that can move back and forth vertically along the clamping base 2. It is located on the left side of the lens clamp, and its Y-axis height is higher than the left short support point of the lens clamp, and its X-axis position is outside the left short support point of the lens clamp. The distance can be set according to the actual lens and lens size. Therefore, when the rotating roller 31 drives the lens to rotate from the left side of the clamping point to the top clamping point of the fixture, the lens clamp is deformed. At the same time, the lens is also fixed to the left side of the clamp. The lens first contacts the left short support point of the clamp, and then the lens and the clamp move together. When the lens contacts the independent limiting column, it stops, fixing the shape of the lens and the clamp, avoiding the risk of the lens falling off after the clamp 1 is deformed.
[0035] Furthermore, considering that the clamp 1 is prone to tilting upwards when subjected to external force, this application also provides a right short-leg limiting arm 6 on the side of the clamp holder 2. The right short-leg limiting arm 6 is mounted on the positioning platform and presses down on the clamp legs by rotating, thereby allowing rotation in the direction of approaching or moving away from the clamp holder 2. When the right short-leg limiting arm 6 rotates above the clamp holder 2, it restricts the clamp 1 vertically between the right short-leg limiting arm 6 and the clamp holder 2, thus preventing the clamp 1 from tilting upwards. The left short-leg limiting arm 9 and the front long-leg limiting arm 10 are mounted on an independent bracket and are powered to press down and release vertically. They can also move laterally without power as the clamp legs open, ensuring that the clamp legs are pressed down throughout the entire process from opening to closing.
[0036] Specifically, the lens lifting platform assembly 8 includes a base 81 and a movable platform 82 for carrying the lens. The output end of the lifter passes through the base 81 and is fixedly connected to the movable platform 82, thereby realizing the lifting effect on the lens.
[0037] Specifically, the roller assembly 3 also includes a motor 32, the output end of the reciprocating driver 4 is connected to an extension frame, the motor 32 is vertically mounted on the extension frame, and the output end of the motor 32 passes through the extension frame and is connected to the roller 31.
[0038] Specifically, the roller assembly 3 and the repeater driver I4 can be installed on the moving platform 82 or set at the same height as the card table 2.
[0039] Specifically, the automatic lens clamping device also includes a long leg movement positioning sensor 7, which is connected to an elastic support base and is located in front of the lens lifting platform assembly 8.
[0040] The rotating roller 31 drives the lens to rotate from the left side of the clamping point to the top clamping point through its own rotation. When the edge of the lens abuts against the left side clamping point and the top clamping point respectively, the top of the clamp 1 abuts against the long leg moving into position sensor 7, thereby driving the elastic support seat to move. If the displacement is within the threshold range, the right support leg 23 is controlled to move and contact the lens, and the right side clamping point retracts to clamp the edge of the lens, thereby realizing that the three clamping points clamp the edge of the lens together.
[0041] The working principle and process of this utility model are as follows:
[0042] When the lens is inserted, the left support leg 21 and the right support leg 23 move along the Y direction of the clamp seat 2, thereby continuously pressing the inside of the clamp 1 through the support leg, and the clamping platform 22 abuts against the outside of the clamp 1, thus cooperating with the inside and outside of the support leg to open the clamp 1 along the X direction.
[0043] The moving stage 82 moves the lens upward, thus entering the range of the extended clamp 1. At this time, the support leg 21 moves back a small range, making the angle of the clamp 1 smaller, until the two clamping points on the left and right sides of the clamp 1 abut the edge of the lens.
[0044] The right short-leg limiting arm 6 rotates to above the clamp seat 2, vertically positioning the clamp 1 between the right short-leg limiting arm 6 and the clamp seat 2 to prevent the clamp 1 from tilting upwards. The left short-leg limiting arm 9 is also vertically positioned, further restricting the clamp 1 between the right short-leg limiting arm 6 and the clamp seat 2 to prevent the clamp 1 from tilting upwards. The front long-leg limiting arm 10 is vertically positioned, limiting the clamp 1 within its pre-set slot to prevent it from tilting upwards.
[0045] The reciprocating drive 4 drives the roller assembly 3 to move along the X direction of the clamp seat 2, thereby causing the roller 31 to abut against the edge of the lens;
[0046] Motor 32 drives roller 31 to rotate. Roller 31 rotates itself, which in turn drives the lens to rotate from the left clamping point to the top clamping point of the clamp. During this process, due to the action of support leg 21, the right clamping point separates from the edge of the lens, thereby achieving clamping of the lens by the top clamping point and the left clamping point. At the same time, the lens rotates with independent limiting mechanism 5. The lens drives the top of clamp 1 to abut against the long leg and move to the positioning sensor 7 and drive the elastic support seat to move. If the displacement is within the threshold range, a stop signal is sent to the rotation mechanism, and a signal is sent to the right support leg 23 to control the right support leg 23 to move. Since clamp 1 is no longer supported, the right clamping point retracts and clamps the edge of the lens, thereby achieving clamping of the lens edge by the three clamping points.
[0047] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
