[0032] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1 to 8 :

[0034] A glass lens bonding process comprises the following steps:

[0035] Step 1, fixing lens 1;

[0036] Step 2: Grab the second lens and move it above the first lens;

[0037] Step 3: Laminate lens 1 and lens 2.

[0038] A glass lens bonding device is applied to a glass lens bonding process, comprising a bottom base 1, a movable seat 2 and a driving unit 3; the bottom base 1 is used to fix lens one, and is provided with a plurality of support columns 11 for supporting the bottom of lens one, and is also provided with a positioning plate 12 for clamping one side of the lens; the movable seat 2 is installed at the working end of the driving unit 3, and a suction cup 21 for adsorbing lens two is provided at the bottom of the movable seat 2, and the suction cup 21 is connected to the working end of a vacuum generator 211, and the vacuum generator 211 is fixedly installed on the movable seat 2, and a plurality of adjustment columns 22 are provided around the suction cup 21, and the adjustment columns 22 are bonded to the upper side of lens two, and each adjustment column 22 moves separately in the vertical direction, and the adjustment columns 22 are used to adjust the angle of lens two adsorbed by the suction cup 21; the support columns 11 and the adjustment columns 22 can both lock their own positions through the locking unit 23; the driving unit 3 is used to drive the movable seat 2 to move in the horizontal and vertical directions.

[0039] The glass lens bonding device in the present application fixes lens one through the bottom base 1. Before starting the bonding work, the staff can take lens one and lens two, place lens one on the bottom base 1, and the support column 11 of the bottom base 1 supports the bottom of lens one. The position of each support column 11 is adjusted to maintain the horizontal state of lens one, and then the locking unit 23 locks the position of the support column 11 so that the subsequent lens one can maintain the same angle after being placed on the support column 11; then the staff can manually bond lens two to the lens one fixed on the bottom base 1, and then move the movable seat 2 down to the adjustment column 22. The adjusting column 22 is fitted with the upper surface of the lens 2, and the adjusting column 22 changes its height position according to the surface curvature of the lens 2. Then the adjusting column 22 is also locked by the locking unit 23 to ensure that the lens 2 adsorbed on the suction cup 21 has the same angle. The more the supporting columns 11 and the adjusting columns 22 are, the more accurate the angle control of the lens 1 and the lens 2 is. The staff can set the number of the supporting columns 11 and the adjusting columns 22 as needed. When the fitting equipment starts working, the staff manually or automatically places the lens 1 into the bottom base 1 through the robotic arm. The supporting column 11 supports the lens 1, and the positioning plate 12 on the side of the bottom base 1 is fixed to the bottom base 1. Move to the side of the lens and fit it, clamp and fix the lens one, while the lens one is fixed on the bottom base 1, the driving unit 3 drives the moving seat 2 to move horizontally to the output end of the lens two feeding device on one side of the bottom base 1, and the driving unit 3 drives the moving seat 2 to move downward so that the adjusting column 22 fits the upper surface of the lens two, and the suction cup 21 between the adjusting columns 22 adsorbs the lens two, so that the lens two moves with the moving seat 2, and the driving unit 3 drives the moving seat 2 and the lens two to move above the bottom base 1, and the driving unit 3 drives the moving seat 2 to move downward so that the lens two and the lens one fit together, and the positioning is completed after the fitting is completed. The plate 12 releases the clamping fixation on the lens one, and the lens one moves along with the lens two. The driving unit 3 drives the movable seat 2 to move to one side of the bottom base 1 to unload the lens one and the lens two after bonding. The bottom base 1 and the movable seat 2 in this embodiment are supported at multiple points according to the surface curvature of the lens one and the lens two through multiple support columns 11 and adjustment columns 22. The support columns 11 and the adjustment columns 22 can adjust the lens one and the lens two to the same angle when bonding the lens one and the lens two with different curvatures and radians, thereby ensuring the same force in each part when bonding the lens one and the lens two, and ensuring the bonding effect.

[0040] In order to solve the problem of how to detect the fit of lens 1 and lens 2, the following features are specifically set:

[0041] The bottom base 1 is also provided with a detection unit 13, which includes a light source 131 and a visual camera 132. The light source 131 is installed between the support columns 11, and the working end of the light source 131 is set upward. The visual camera 132 is used to check the position of the light emitted by the light source 131 after being refracted by the lens one and the lens two after bonding.

[0042] In this embodiment, a detection unit 13 is also provided on the bottom base 1, and the detection unit 13 detects the fitting effect of lens one and lens two. When the movable seat 2 drives lens two to move down and fit with lens one, the light source 131 located between the support columns 11 emits light upward. The light source 131 can be a laser emitter, etc. The light emitted by the light source 131 to the fitted lens one and lens two is refracted and falls on the bottom of the movable seat 2. The visual camera 132 checks the laser irradiation position at the bottom of the movable seat 2. The laser point after refraction of lens one and lens two after each fitting should be consistent with the laser point refracted by lens one and lens two when the positions of the support column 11 and the adjustment column 22 are determined before processing. If the laser landing point detected by the visual camera 132 is offset greatly, it proves that there is a deviation in the fitting effect of lens one and lens two, so that the staff can be reminded in time to readjust the positions of the support column 11 and the adjustment column 22 to ensure the subsequent fitting accuracy.

[0043] In order to solve the problem of how the support column 11 can adaptively adjust the bottom of lenses with different curvatures, the following features are specifically set:

[0044] The top of the support column 11 is a round head, and the support column 11 is inserted into the mounting hole 111 set on the bottom base 1, and the mounting holes 111 are distributed around the detection unit 13; a first spring 112 is set inside the mounting hole 111, and the first spring 112 elastically connects the support column 11 and the bottom of the mounting hole 111, and the first spring 112 applies elastic force to move the support column 11 upward.

[0045] The support column 11 in this embodiment is inserted into the mounting hole 111 of the bottom base 1, and the first spring 112 arranged inside the mounting hole 111 applies elastic force to move the support column 11 upward. The mounting hole 111 should ensure that the support column 11 cannot be separated from the mounting hole 111. The support column 11 remains at the highest point under the elastic force of the first spring 112. When the lens 1 is placed on the bottom base 1, the support column 11 compresses the first spring 112 to move downward when the lens 1 is pressed down. The round head end at the top of the support column 11 can effectively fit with the bottom of the lens 1 with different curvatures. When the lens 1 remains stable, the locking unit 23 fixes the position of each support column 11 to ensure that the lens 1 placed on the support column 11 maintains the same position and angle in subsequent work.

[0046] In order to solve the problem of how the positioning plate 12 automatically clamps and fixes lenses of different models, the following features are specifically set:

[0047] The positioning plate 12 is arranged on the upper peripheral side of the bottom base 1, and the positioning plate 12 is inserted into the bottom base 1 through a guide column 121, and the axis of the guide column 121 is arranged horizontally; a top plate 122 is provided at the top of the guide column 121, and a second spring 123 is sleeved on the guide column 121, and the second spring 123 elastically connects the bottom base 1 and the top plate 122, and the second spring 123 applies an elastic force to move the positioning plate 12 outward; the positioning plates 12 opposite to each other on both sides of the bottom base 1 make relative synchronous movement when the moving base 2 moves downward.

[0048] In this embodiment, positioning plates 12 are provided on all four sides of the bottom base 1. The positioning plates 12 are inserted into the side of the bottom base 1 through guide columns 121 to maintain horizontal movement. The second spring 123 sleeved on the guide column 121 applies elastic force to the guide column 121 to fit the side wall of the bottom base 1. When the movable seat 2 drives the lens 2 to move downward, the two positioning plates 12 located on the opposite side of the bottom base 1 make relative synchronous movement, so that the lens 1 on the support column 11 can be centered and clamped to ensure that the position of the lens 1 is the same each time it is fitted.

[0049] In order to achieve the purpose of relative synchronous movement of the positioning plates 12 on both sides of the bottom base 1 when the moving base 2 moves downward, the following features are specifically set:

[0050] The bottom base 1 is provided with a mounting groove 124 on the side facing outward of the positioning plate 12, and a first pressing block 125 is slidably installed in the mounting groove 124. The first pressing block 125 moves in the vertical direction, and a slope 126 is provided on the side of the first pressing block 12 facing the positioning plate 12. The slope 126 fits the positioning plate 12, and a third spring 127 is provided in the first pressing block 125. The third spring 127 is elastically connected to the first pressing block 125, and the third spring 127 exerts Add elastic force to move the first pressing block 125 upward; a second pressing block 24 is provided on the peripheral side of the movable seat 2, and the second pressing block 24 is located above the first pressing block 125. The movable seat 2 follows the second pressing block 24 to move downward to press the first pressing block 125; the second pressing block 24 is inserted into the movable seat 2 through a guide rod 241 extending vertically from the upper side, and a fourth spring 242 is provided on the guide rod 241, and the fourth spring 242 applies elastic force to restore the second pressing block 24.

[0051] The bottom surface of the second pressing block 24 is lower than the bottom ends of the suction cup 21 and the adjusting column 22 in the non-working state; the elastic coefficient of the fourth spring 242 is greater than the elastic coefficient of the third spring 127.

[0052] When the movable seat 2 in this embodiment moves downward, it will drive the second pressing block 24 on the side of the movable seat 2 to move downward. The bottom surface of the second pressing block 24 is at a lower position and will first contact the first pressing block 125 of the bottom base 1. Since the elastic coefficient of the fourth spring 242 is greater than the elastic coefficient of the third spring 127, the downward movement of the movable seat 2 will preferably drive the first pressing block 125 to move downward and compress the third spring 127. When the first pressing block 125 moves downward, the inclined surface 126 contacts one side of the positioning plate 12 and pushes the positioning plate 12 to move along the axial direction of the guide column 121, thereby realizing the relative positioning plates 12 on both sides of the bottom base 1. When the moving seat 2 moves downward, it makes relative synchronous movement. When the positioning plates 12 all contact the peripheral side of the lens one to clamp the lens one, the moving seat 2 moves downward relative to the second pressing block 24, so that the lens two is fitted with the lens one. When the moving seat 2 is reset, the elastic force of the fourth spring 242 causes the second pressing block 24 to reset and follow the moving seat 2 to move upward. After the second pressing block 24 is separated from the first pressing block 125, the first pressing block 125 is reset under the elastic force of the third spring 127, and the positioning plate 12 is reset under the elastic force of the second spring 123. The contact clamping of the lens one makes the fitted lens one and lens two move with the moving seat 2.

[0053] In order to ensure that the positioning plate 12 can clamp the lens 1, the following features are specifically set:

[0054] The top position of the positioning plate 12 is higher than the top height of the support column 11 in a non-stressed state, and the straight-line distance between the suction cup 21 and the bottom of the movable seat 2 is greater than the height of the positioning plate 12 .

[0055] In this embodiment, the top position of the positioning plate 12 is higher than the top height of the support column 11 in a non-stressed state, thereby ensuring that the positioning plate 12 can effectively fit around the periphery of the support column 11 to clamp a lens of any weight once it is placed on the support column 11.

[0056] In order to solve the problem of how the locking unit 23 locks the support column 11 and the adjustment column 22, the following features are specifically provided:

[0057] The adjusting column 22 is inserted into the through hole 221 provided on the moving seat 2. The bottom end of the adjusting column 22 is a round head, and the top of the adjusting column 22 passes through the through hole 221 and extends to the upper side of the moving seat 2; the locking unit 23 is provided on the upper side of the moving seat 2, and the locking unit 23 includes two clamping blocks 231, and the clamping blocks 231 are respectively located on one side of the adjusting column 22. The position of the clamping block 231 facing the adjusting column 22 is provided with a scissor-shaped groove 232, and the opening of the scissor-shaped groove 232 is provided toward the adjusting column 22; the clamping block 231 is installed at the working end of the finger cylinder 233, and the finger cylinder 233 drives the scissor-shaped groove 232 of the clamping block 231 to fit the surrounding side of the adjusting column 22 to clamp the adjusting column 22.

[0058] In this embodiment, there are four support columns 11 and four adjustment columns 22. Taking the adjustment column 22 as an example, the locking unit 23 includes two clamping blocks 231 arranged on one side of the adjustment column 22. The clamping blocks 231 are provided with scissor-shaped grooves 232 opposite to the position of the adjustment column 22. When the adjustment column 22 fits and positions the lens 2 before processing, the finger cylinder 233 of the locking unit 23 drives the two clamping blocks 231 away from the adjustment column 22, so that the adjustment column 22 can move freely along the axis of the through hole 221. When all the adjustment columns 22 fit the surface of the lens 2, the finger cylinder 233 drives the clamping blocks 231 to fit the adjustment column 22. The scissor-shaped grooves 232 can effectively fit the peripheral side of the adjustment column 22, thereby cooperating with the through hole 221 to lock the adjustment column 22, ensuring that the position of the adjustment column 22 is fixed in subsequent work, so that each lens adsorbed by the suction cup 21 is kept at the same angle.

[0059] In order to solve the problem of how the driving unit 3 drives the movable base 2 to move in the horizontal and vertical directions, the following features are specifically set:

[0060] The driving unit 3 includes a first linear drive 31 and a second linear drive 32. The movable base 2 is fixedly mounted on the working end of the second linear drive 32, and the second linear drive 32 is used to drive the movable base 2 to move in the vertical direction; the second linear drive 32 is fixedly mounted on the working end of the first linear drive 31, and the first linear drive 31 is used to drive the movable base 2 to move in the horizontal direction.

[0061] In this embodiment, the driving unit 3 drives the movable base 2 to move through the first linear drive 31 and the second linear drive 32. The first linear drive 31 can be a synchronous belt slide or other devices, and the second linear drive 32 can be a linear cylinder or an electric push rod, etc. The first linear drive 31 and the second linear drive 32 are both common electronic components, ensuring that the movable base 2 can move accurately between the lens loading device, the movable base 2 and the unloading device.

[0062] Working principle: Before starting the bonding work, the staff can take the bonded lens 1 and lens 2 and place them on the bottom base 1, adjust the positions of the support columns 11 and the adjustment columns 22, so that all the support columns 11 and the adjustment columns 22 are bonded to the surfaces of the lens 1 and lens 2, and then lock them through the locking unit 23. When the bonding equipment starts working, the staff can manually or automatically place the lens 1 into the bottom base 1 through the robot arm. The support columns 11 support the lens 1, and the driving unit 3 drives the moving base 2 to move horizontally to the output end of the lens 2 feeding device on one side of the bottom base 1 to pick up the material. The adjustment columns 22 are bonded to the upper surface of the lens 2, and the space between the adjustment columns 22 is adjusted. The suction cup 21 absorbs the lens 2 so that the lens 2 moves along with the moving seat 2. The driving unit 3 then drives the moving seat 2 to move downward above the bottom base 1. The moving seat 2 moves downward to drive the positioning plate 12 on the side of the bottom base 1 to move synchronously to clamp and fix the lens 1. The moving seat 2 moves downward to make the lens 2 fit with the lens 1. After the fitting is completed, the detection unit 13 detects the fitting effect of the lens 1 and the lens 2. Then the moving seat 2 moves upward, and the positioning plate 12 releases the clamping and fixation of the lens 1. The lens 1 moves along with the lens 2. The driving unit 3 drives the moving seat 2 to move to the side of the bottom base 1 to unload the fitted lens 1 and the lens 2.

[0063] The above embodiments merely represent one or several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
