Description

Technical Field

[0001] This invention relates to the field of lens processing technology, specifically to an AR lens double-sided lamination machine. Background Technology

[0002] With the rapid development of augmented reality (AR) technology, lenses are increasingly being used in smart glasses, virtual reality devices, and other fields. In the lens manufacturing process, the bonding process between the film and the lens is one of the key steps. Existing lens bonding technologies typically employ manual or semi-automated methods, which are not only inefficient but also prone to insufficient bonding precision, affecting the quality of the final product. Existing technologies suffer from the following main problems in the bonding process: Inefficient: Traditional bonding methods require manual operation, resulting in low production efficiency and making it difficult to meet the needs of large-scale production; Insufficient bonding precision: Manual operation can easily lead to inaccurate alignment between the diaphragm and the lens, affecting the optical performance of the product; Complex operation: Existing equipment often requires multiple independent processes for feeding, bonding and unloading, which makes the operation process cumbersome and increases the possibility of errors. Inadequate testing: The lack of effective testing methods during the loading and bonding of films and lenses can easily lead to substandard products entering the market.

The lens loading mechanism 200 is used to load and inspect the lenses, and then place the lenses at the conveying end of the conveying mechanism 400. The film feeding mechanism 113 is used to feed the film, tear the film, and inspect it before placing the film in the lower bonding device 105. The unloading mechanism 300 is used to unload the laminated lenses; And a conveying mechanism 400, used to sequentially convey lenses from the loading mechanism to the bonding mechanism and the unloading mechanism 300 and place the lenses on the upper bonding device 101.

[0028] Specifically, the lens loading mechanism 200 includes a first loading bin assembly 201, a second loading bin assembly 202, a loading platform 203, a first lifting tray assembly 206, a second lifting tray assembly 207, a loading transverse movement mechanism 208, a loading three-axis robot arm 204, and a loading detection camera 205.

Both the first feeding bin assembly 201 and the second feeding bin assembly 202 are used to store material trays. The first lifting tray assembly 206 is used to remove the material tray from the first feeding bin assembly 201. The material picking and traversing mechanism 208 is used to drive the material picking platform 203 to traverse between the first lifting tray assembly 206 and the second lifting tray assembly 207 to pick up the material tray. The second lifting tray assembly 207 is used to remove the material tray from the material picking platform 203 and place it in the second feeding bin assembly 202.

The feeding three-axis robot 204 is used to remove the lens located in the material tray and place it in the conveying end of the conveying mechanism 400.

[0029] In this embodiment, the first loading bin assembly 201 holds a tray containing a lens for processing, and the second loading bin assembly 202 holds a tray with the lens removed. After the first lifting tray assembly 206 removes the tray from the first loading bin assembly 201, the material handling traversing mechanism 208 drives the material handling platform 203 to move below the tray, and the first lifting tray assembly 206 places the tray on the material handling platform 203. Subsequently, the material handling platform 203 moves between the first loading bin assembly 201 and the second loading bin assembly 202, and the tray is then placed on the material handling platform 203. The three-axis robotic arm 204 removes the lens and places it on the lens fixture 403 of the conveyor belt 401. During this process, the loading detection camera 205 identifies the position of the lens to make fine adjustments to the three-axis robotic arm 204. The picking and traversing mechanism 208 drives the picking platform 203 to move above the second loading bin assembly 202. The second lifting tray assembly 207 removes the tray. After the picking platform 203 is removed, the tray is placed back into the second loading bin assembly 202, completing the loading of the lens and the picking and placing of the tray.

[0030] In this embodiment, the first lifting tray assembly 206 and the second lifting tray component 207 are preferably structures composed of at least a motor, a screw, a nut, a slide rail, a slider, and a suction cup; the material handling and transverse movement mechanism 208 is preferably a structure composed of at least a motor, a synchronous pulley, a synchronous belt, and a slider. The structure and principle of the above structures are existing technologies and will not be described in detail here.

[0031] Specifically, the conveying mechanism 400 includes a conveyor belt 401 and a six-axis robot 402. The surface of the conveyor belt 401 is equipped with a plurality of spaced-apart lens fixtures 403. The end of the six-axis robot 402 is equipped with a suction cup 404, a transfer detection camera 405 and a ring light source 406. The transfer detection camera 405, in conjunction with the ring light source 406, positions the lens and the suction cup 404 picks up the lens.

[0032] Specifically, the double-sided lens bonding machine also includes a USC mechanism 115 located between the lens feeding mechanism 200 and the conveying mechanism 400, through which the lens is cleaned.

[0033] Specifically, there are two bonding mechanisms and two film feeding mechanisms 113. The two bonding mechanisms are arranged at intervals and are used to bond the concave and convex surfaces of the lens respectively. The two film feeding mechanisms 113 are located on one side of the two bonding mechanisms respectively to feed the film, peel off the film, and inspect it. Then, the film is placed in the lower bonding device 105 of the corresponding bonding mechanism. The double-sided lens bonding machine also includes a lens flipping mechanism 114 for flipping the lens located in the conveying mechanism 400. The lens flipping mechanism 114 is located on one side of the conveying mechanism 400 and between the two bonding mechanisms.

[0034] In this embodiment, two sets of bonding mechanisms and a film feeding mechanism 113 are provided to apply films to the concave and convex surfaces of the lens respectively. Specifically, after the lens is bonded by the first bonding mechanism, a six-axis robot removes the lens from the bonding mechanism and places it on the lens fixture 403 of the conveyor belt 401. During the conveying process on the conveyor belt 401, the lens is flipped by the lens flipping mechanism 114, and then the six-axis robot removes the lens and places it on the second bonding mechanism for bonding. In this embodiment, the lens flipping mechanism 114 is preferably a structure consisting of at least a rotary motor and pneumatic fingers. The structure and principle of the above structure are existing technologies and will not be described in detail here.

[0035] Specifically, the upper bonding device 101 includes an upper cavity mold 102, an upper cavity fixture assembly 103 disposed within the upper cavity mold 102, and an upper cavity clamping assembly 104. The upper cavity fixture assembly 103 is used to place the lens, and the upper cavity clamping assembly 104 is used to fix the lens within the upper cavity fixture assembly 103. The specific structure of the upper cavity fixture assembly 103 can be found in [reference needed]. Figure 6 As can be seen, after the six-axis robotic arm places the lens into the upper cavity fixture assembly 103, the upper cavity clamping assembly 104 clamps the lens. In this embodiment, the upper cavity clamping assembly 104 is preferably a cylinder.

[0036] In this embodiment, the bonding drive mechanism includes an upper cavity lifting drive assembly 112 for driving the upper cavity mold 102 to rise and fall. The upper cavity mold 102 is driven to rise and fall by the upper cavity lifting drive assembly 112, so that the upper cavity mold 102 and the lower cavity mold 109 can be bonded and separated, completing the bonding of the lens and the film. In this embodiment, the upper cavity lifting drive assembly 112 is preferably a structure consisting of at least a motor, a screw, a nut, a slide rail, and a slider. The structure and principle of the above structures are existing technologies and will not be described in detail here.

[0037] In addition, the bonding machine in this embodiment also integrates a vacuum pump. When the lens and the film are bonded, the vacuum pump evacuates the upper cavity mold 102 and the lower cavity mold 109 to improve the bonding effect between the lens and the film.

[0038] Specifically, the lower bonding device 105 includes a lower cavity mounting platform 106, a lower cavity correction platform 107 mounted on the lower cavity mounting platform 106, a lens placement platform 108, a lower cavity mold 109 mounted on the output end of the lower cavity correction platform 107, and a diaphragm conforming assembly 110 mounted in the lower cavity mold 109; the lower cavity correction platform 107 is used to detect and calibrate the position of the lower cavity mold 109, the lens placement platform 108 is used to temporarily store the lens, and the diaphragm conforming assembly 110 is used to place and position the diaphragm.

[0039] In this embodiment, the specific structure of the diaphragm contouring assembly 110 can be referred to Figure 7 It adapts to the shape of the concave or convex surface of the lens to predetermine the shape and position of the diaphragm.

[0040] In addition, the lower bonding device 105 also includes a lower bonding transverse movement mechanism 111. The lower cavity mounting platform 106 is installed at the output end of the lower bonding transverse movement mechanism 111. The lower bonding transverse movement mechanism 111 is used to drive the lower cavity mounting platform 106 to move closer to or away from the conveying mechanism 400. The six-axis robot places the clamped lens on the lens placement platform 108. The lower bonding and lateral movement mechanism 111 drives the lens placement platform 108 to move laterally to directly below the upper cavity mold 102. Then, the upper cavity lifting drive assembly 112 drives the upper cavity fixture assembly 103 of the upper cavity mold 102 to descend and cooperate with the lens. At the same time, the upper cavity clamping assembly 104 clamps the lens, completing the lens loading. At this time, the diaphragm shaping assembly 110 in the lower cavity mold 109 is located below the diaphragm loading mechanism 113. After the diaphragm loading mechanism 113 loads, tears, and inspects the sheet material, it places the diaphragm into the diaphragm shaping assembly 110, completing the diaphragm loading.

[0041] Subsequently, the lower bonding and transverse movement mechanism 111 drives the diaphragm conforming assembly 110 in the lower cavity mold 109 to align with the upper cavity fixture assembly 103 in the upper cavity mold 102. During this process, the lower cavity correction platform 107 detects the position of the lens and makes minor adjustments to the position of the lower cavity mold 109. Then, the upper cavity lifting drive assembly 112 drives the upper cavity fixture assembly 103 of the upper cavity mold 102 to descend and bond with the diaphragm conforming assembly 110, thus completing the bonding of the lens and the diaphragm.

[0042] In this embodiment, the lower cavity correction platform 107 is preferably a structure consisting of at least a servo motor, a reducer, a ball screw, a pressure sensor, and a sealing assembly; the lower bonding transverse movement mechanism 111 is preferably a structure consisting of at least a servo motor, a reducer, a screw, a nut, a slide rail, and a slider. The structure and principle of the above structures are existing technologies and will not be described in detail here.

[0043] Specifically, the unloading mechanism 300 includes a three-axis unloading robot 301, a plurality of unloading platforms 302, and an unloading bin assembly 303 corresponding to the number of unloading platforms 302; The feeding platform 302 is used to place the material tray, the unloading bin assembly 303 is used to store the material tray and drive the material tray to rise and fall, and the unloading three-axis robot 301 is used to take out the empty material tray located on the feeding platform 302 and place it on the feeding platform 302 or take out the full material tray and place it on the unloading bin assembly 303.

[0044] In this embodiment, the conveyor belt 401 transports the laminated lens to the corresponding area, and the unloading three-axis robot 301 takes out the lens and places it on the material tray of the unloading platform 302. Then, the material tray is taken out from the unloading platform 302 and placed in the unloading bin assembly 303 to complete the unloading.

[0045] In summary, the AR lens double-sided bonding machine of this embodiment uses the upper bonding device 101 and the lower bonding device 105 in the bonding mechanism to accurately accommodate and position the lens and the film, ensuring consistency at the starting point of the bonding process. The bonding drive mechanism can precisely control the movement trajectory and pressure of the upper and lower bonding devices 105, ensuring that the film and lens are bonded evenly and smoothly after alignment, minimizing the generation of bubbles and positional deviations. In addition, the lens loading mechanism 200 and the film loading mechanism 113 realize automated loading of lenses and films, including detection and positioning, eliminating manual operation. The unloading mechanism 300 is responsible for automatically unloading the products after bonding. The conveying mechanism 400 automatically and sequentially transports the lenses between different workstations, realizing a complete automated production process from loading to bonding to unloading, further improving the continuity and efficiency of production.
