Detailed Implementation

[0045] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0046] In this utility model, the descriptions involving "first," "second," "upper," and "lower," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," "upper," or "lower" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. Where the technical solutions of the embodiments can be combined, they are all within the protection scope claimed by this utility model.

[0047] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, a lens mounting system includes a mounting device 100 and a height detection device 200. The mounting device 100 includes a heating device 110, a loading device 120, and a mounting device 130. The heating device 110 carries the lens and heats it. The loading device 120 includes a transition fixture 122 and a front / back detection mechanism 124. The transition fixture 122 carries an outer pressure ring. The front / back detection mechanism 124 detects the placement state of the outer pressure ring on the transition fixture 122. The mounting device 130 includes a mounting clamp 132 and an outer pressure ring mounting mechanism 131. The mounting clamp 132 is movable along the Y-axis and secures the lens. The outer pressure ring mounting mechanism 131 has a mounting component that is movable along the X and Z axes and picks up the outer pressure ring. Height detection device 200 is used to detect the height of the lens assembly after it is locked in place.

[0049] During the locking operation, the lens is first placed on the heating device 110 to heat it. Heating the lens facilitates subsequent ring pressing, reducing the difficulty of the ring pressing operation. The heated lens is then clamped by the locking fixture 132, and the outer ring is placed on the transition fixture 122. The orientation detection mechanism 124 detects whether the outer ring is placed correctly or incorrectly. If the outer ring is correctly placed, it is picked up and clamped by the locking assembly; if it is incorrectly placed, it is placed in the receiving box 125. The outer ring locking mechanism 131 and the locking fixture 132 move relative to each other to lock the outer ring and lens. After locking, the outer ring and lens are placed on the height detection device 200 for height detection. Lenses that pass the height detection are received into the receiving warehouse; lenses that fail are returned for reoperation or discarded.

[0050] As one embodiment, the locking clamp 132 is disposed on a slide rail disposed along the Y-axis direction, and the locking clamp 132 is fixed on a Y-axis slider that can slide along the Y-axis slide rail.

[0051] The lens mounting system described above facilitates mounting operations, improves mounting efficiency, ensures the mounting quality of all lenses, and enhances quality inspection efficiency.

[0052] Furthermore, such as Figure 4 As shown, the transition fixture 122 is mounted on an X-axis track and can move along the X-axis. The forward and reverse detection mechanism 124 is located on one side of the transition fixture 122 along the X-axis. The transition fixture 122 has a placement platform with a U-shaped groove extending along the Y-axis, the opening of which is located at the edge of the platform. A push rod is located at the lower part of the U-shaped groove, and the push rod can extend and retract along the Z-axis.

[0053] Both the outer pressure ring locking mechanism 131 and the transition fixture 122 can move along the X-axis. After the outer pressure ring is placed on the placement platform of the transition fixture 122 and inspected, the upright outer pressure ring is picked up by the outer pressure ring locking mechanism 131. At this time, to facilitate picking up, the outer pressure ring locking mechanism 131 and the transition fixture 122 move to a relative position along the X-axis. The outer pressure ring locking mechanism 131 picks up the outer pressure ring by moving along the Z-axis. When picking up the outer pressure ring, the outer pressure ring is lifted by the push rod of the transition fixture 122 for easy picking up.

[0054] Furthermore, the feeding device 120 also includes: a feeding platform 121, which is provided with a receiving groove, and an output groove is provided at one end of the receiving groove near the transition fixture 122. The width of the receiving groove is greater than the width of the output groove, and the opening of the output groove is opposite to the opening of the U-shaped groove. The feeding platform 121 is driven to vibrate by a vibration driver; a pushing mechanism 123 is disposed at the other end of the X-axis track opposite to the forward and reverse detection mechanism 124. The pushing mechanism 123 is provided with a telescopic rod, and the height of the telescopic rod is higher than the upper surface of the placement platform.

[0055] During loading, the transition fixture 122 moves along the X-axis, aligning the opening of the U-shaped groove with the output groove of the loading platform 121. The loading platform 121 vibrates via a vibration driver, causing the outer pressure ring placed in the receiving groove to move towards the output groove and then into the U-shaped groove. The placement status of the outer pressure ring is detected by the forward / reverse detection mechanism 124. As an example, the forward / reverse detection mechanism 124 is equipped with a fiber optic sensor. During installation, the light position of the fiber optic sensor is adjusted. If the outer pressure ring is placed upright, the light shining on it is reflected back to the fiber optic sensor; if the outer pressure ring is placed backward, the fiber optic sensor does not receive the reflected light. The pushing mechanism 123 is a needle-type cylinder. When the backward placement of the outer pressure ring is detected, the transition fixture 122 moves along the X-axis to the pushing mechanism 123, the push rod lifts the outer pressure ring, the needle-type cylinder is activated, and the piston pushes the outer pressure ring out of the U-shaped groove. In one implementation, a receiving box 125 is provided at a position opposite to the needle cylinder. The outer pressure ring is pushed into the receiving box 125. When the outer pressure rings in the receiving box 125 accumulate to a certain number, the outer pressure rings are placed back into the receiving slot of the loading platform 121, and the loading operation is repeated.

[0056] Furthermore, the transition fixture 122 is provided with an X-axis slide rail arranged along the X-axis direction below it, and the bottom of the transition fixture 122 is an X-axis slider that can slide along the X-axis slide rail. In order to facilitate the outer pressure ring locking mechanism 131 to pick up the outer pressure ring, the outer pressure ring locking mechanism 131 and the transition fixture 122 need to be able to move relative to each other in the Y-axis direction. Therefore, preferably, the X-axis slide rail is arranged on the Y-axis slider.

[0057] Furthermore, two or more of the feeding device 120 and the locking device 130 are arranged side by side along the X-axis.

[0058] By setting up two or more loading devices 120 and locking devices 130, more than two lens locking operations can be performed simultaneously, which improves the efficiency of the locking operation.

[0059] Furthermore, the lens locking system also includes a receiving device 300, wherein the locking device 100, the height detection device 200, and the receiving device 300 are arranged sequentially along the X-axis.

[0060] After passing the height inspection, qualified products are transferred to the receiving equipment 300.

[0061] Furthermore, the receiving device 300 includes a receiving tray and a receiving chamber. The receiving tray is movable along the Y-axis, and the receiving chamber is located at one end of the moving direction of the receiving tray.

[0062] First, qualified lenses are placed in a receiving tray. The receiving tray has multiple holding slots, each holding one lens. Once the receiving tray is full, it is placed in the receiving warehouse. Multiple receiving trays are stacked in the receiving warehouse.

[0063] Furthermore, the lens locking system further includes a robotic arm device 400, comprising a gantry frame 430 and a robotic arm assembly. Two uprights of the gantry frame 430 are positioned on either side of the locking device 100 and the receiving device 300, with the tops of the two uprights connected by a crossbeam. The robotic arm assembly is slidably connected to the crossbeam and includes a robotic arm capable of moving along the Z-axis.

[0064] As previously described, the locking device 100, height detection device 200, and receiving device 300 are arranged sequentially along the X-axis. A gantry frame 430 spans both sides of the locking device 100 and the receiving device 300; therefore, the crossbeam extends along the X-axis. A robotic arm 400, movable along the X-axis, is mounted on the crossbeam. The robotic arm 400 places the heated lens from the heating device 110 onto the locking clamp 132. After locking, the robotic arm 400 picks up the lens and places it on the height detection device 200 for height detection. After detection, the robotic arm 400 picks up the lens and places it in the receiving tray or the non-conforming product collection area.

[0065] Furthermore, the robotic arm device includes a loading robotic arm 410 and a receiving robotic arm 420.

[0066] Because the gantry 430 has a large span, a loading robot 410 and a unloading robot 420 are installed to perform loading and unloading operations respectively. Simultaneously, the two robots perform loading and unloading operations at the same time, further improving operational efficiency.

[0067] Furthermore, such as Figure 5 As shown, the height detection device 200 includes a detection device 210, which includes a base 211 and a detection head 212. The detection head 212 is disposed above the base 211 and is movable along the Z-axis. A measuring gauge 213 is provided on the detection head 212.

[0068] The locked lens is placed on the base 211. The detection head 212 contacts the top of the outer pressure ring, and the lens height is detected by the detector 213. The value of the detector 213 is read. When the height value is within the threshold range, the lens is a qualified product and is transferred to the receiving tray by the receiving robot 420. If the height value exceeds the threshold range, the lens is considered a non-qualified product and is sent to the non-qualified product area by the robot for correction or waste gas treatment.

[0069] Furthermore, the height detection device 200 also includes a transfer device 220, which is disposed between the detection device 210 and the robotic arm device 400. The transfer device 220 includes a transfer base 221 and a gripper 222, which is rotatable along the Z-axis. Two grippers 222 are arranged opposite each other along the Y-axis.

[0070] A detection head 212 is located above the height detection device 200. The detection head 212 and the base 211 are aligned in the Z-axis direction. When the receiving robot 420 picks up the locked lens and places it on the base 211, it may interfere with the height detection device 200. To avoid interference between the receiving robot 420 and the height detection device 200, a transfer device 220 is installed between them. First, the receiving robot 420 picks up the lens and places it on the transfer seat 221. Then, the receiving robot 420 moves away and clamps the lens onto the base 211 using the gripper 222. To improve efficiency, two grippers 222 are arranged opposite each other, and the two grippers 222 can rotate around the Z-axis. By rotating the two grippers 222 around the Z-axis, one gripper 222 clamps the locked lens and places it on the base 211, while the other gripper 222 clamps the inspected lens, rotates it 180°, and places it on the transfer seat 221. The receiving robot 420 picks up the lens according to the judgment of qualified products and moves it to the corresponding position.

[0071] While the present invention has been disclosed above, it is not limited thereto.
