[0032] This embodiment discloses a lens assembly line, including a lens assembly machine, wherein, according to different assembly processes, the lens assembly machine can be used to assemble lenses into a lens barrel, and can also be used to assemble accessories, such as light shielding sheets, into the lens barrel. The lens barrel assembly machine includes a conveyor line and a flip mechanism, the flip mechanism is installed on one side of the conveyor line, the conveyor line is used to convey a carrier with a semi-finished lens placed thereon, and the flip mechanism is used to flip the carrier over to facilitate bidirectional assembly of the semi-finished lens in the carrier, and the structure of the flip mechanism is described in detail below.

[0033] Please refer to Figure 1 and Figure 2 The flip mechanism includes a bracket 100, a first clamping arm 200, a second clamping arm 300, a synchronous shaft 400 and a flip driving cylinder 500. A lifting slider 110 is slidably mounted on the bracket 100. The first clamping arm 200 is slidably mounted on the lifting slider 110. The end of the first clamping arm 200 is rotatably mounted with a first clamping claw 210. The second clamping arm 300 is slidably mounted on the lifting slider 110 and arranged opposite to the first clamping arm 200 to form a carrier clamping position. The first clamping arm 200 and the second clamping arm 300 can move toward or away from each other. The second clamping arm 300 is rotatably mounted with the second clamping claw 310 at the end thereof, the two ends of the synchronous shaft 400 are respectively connected to the first clamping arm 200 and the second clamping arm 300, the first end of the synchronous shaft 400 is connected to the first clamping claw 210 via the first transmission belt 220, the second end of the synchronous shaft 400 is connected to the second clamping claw 310 via the second transmission belt 320, the flip driving cylinder 500 is mounted on the first clamping arm 200 and connected to the first transmission belt 220, or, is mounted on the second clamping arm 300 and connected to the second transmission belt 320. Among them, a longitudinally arranged guide rail is provided on the bracket 100, and the lifting slider 110 is slidably mounted on the guide rail and is connected to the lifting driving cylinder.

[0034] When in use, the first clamping arm 200 and the second clamping arm 300 are located above the conveyor line. The first clamping arm 200 and the second clamping arm 300 respectively drive the first clamping jaw 210 and the second clamping jaw 310 to clamp the lens carrier, and realize the lifting movement through the lifting slider 110 to avoid the interference of the lens carrier with the conveyor line during the flipping process. According to the different installation positions of the flipping drive cylinder 500, the flipping drive cylinder 500 converts the linear motion into rotational motion through the first transmission belt 220 or the second transmission belt 320 to realize the rapid rotation of the first clamping jaw 210 or the second clamping jaw 310, and the first clamping jaw 210 and the second clamping jaw 310 realize synchronous rotation through the first transmission belt 220, the second transmission belt 320 and the synchronization shaft 400, so that the lens carrier can be flipped over, thereby realizing batch assembly of multiple lenses in the lens carrier.

[0035] Please refer to Figure 1 A first slide rail 111 arranged laterally is provided on the lifting slider 110, and the first clamping arm 200 and the second clamping arm 300 are installed on the first slide rail 111. A clamping drive cylinder 112 is connected between the first clamping arm 200 and the second clamping arm 300. The clamping drive cylinder 112 adopts a two-head bidirectional drive cylinder. The synchronous movement of the first clamping arm 200 and the second clamping arm 300 can be achieved through a single cylinder, which can ensure the synchronization of the first clamping arm 200 and the second clamping arm 300, and is conducive to simplifying the structure and realizing a miniaturized design.

[0036] Please continue to refer to Figure 1 In some application examples, the synchronous shaft 400 includes a telescopic sleeve 410 and a telescopic rod 420. The telescopic sleeve 410 is provided with a rotation limiter, which may be a protrusion or a pin or other structure. The telescopic rod 420 is provided with a limit guide groove extending along the axial direction. The telescopic sleeve 410 is sleeved with the telescopic rod 420, and the rotation limiter is adapted to be installed in the limit guide groove. The telescopic sleeve 410 and the telescopic rod 420 are rotatably installed on the first clamping arm 200 and the second clamping arm 300, respectively. When the first clamping arm 2 00 and the second clamping arm 300 move relative to each other, the telescopic sleeve 410 and the telescopic rod 420 move relative to each other along the axial direction, and when the power of the flip driving cylinder 500 is transmitted to the first transmission belt 220 or the second transmission belt 320, due to the limited cooperation between the rotation limit part and the limited guide groove, the telescopic sleeve 410 and the telescopic rod 420 are limited in the circumferential direction, so that the telescopic sleeve 410 and the telescopic rod 420 can rotate synchronously, and then the first clamping jaw 210 and the second clamping jaw 310 rotate synchronously. Alternatively, in other application examples, the synchronous shaft 400 can adopt a matching structure of a spline shaft and a spline sleeve, and the action principle is similar to that of the telescopic sleeve 410 and the telescopic rod 420, which will not be repeated.

[0037] Please continue to refer to Figure 1In some application examples, the first clamping arm 200 is provided with a second slide rail 201, and a driving slider 202 is installed on the second slide rail 201. The driving slider 202 is connected to the first transmission belt 220 and the flip driving cylinder 500. When the lens carrier needs to be flipped, the driving slider 202 moves linearly along the second slide rail 201 under the power of the flip driving cylinder 500, and transmits the power to the first clamping claw 210 through the first transmission belt 220, so that the first clamping claw 210 rotates, and the flipping action is smooth and fast.

[0038] Alternatively, in some other application examples (not shown), the second clamping arm 300 is provided with a second slide rail 201, the second slide rail 201 is provided with a driving slider 202, and the driving slider 202 is connected to the second transmission belt 320 and the flip driving cylinder 500. Different from the above application examples, the flip driving cylinder 500 and the second slide rail 201 can be installed on the second clamping arm 300, so that the power of the flip driving cylinder 500 is transmitted to the second clamping claw 310 through the driving slider 202 and the second transmission belt 320.

[0039] Please refer to Figure 1 A first buffer 510 is provided on the second slide rail 201 and on the sliding path of the driving slider 202. The first buffer 510 is used to stop and buffer the driving slider 202. By fine-tuning the installation position of the first buffer 510, the moving stroke of the driving slider 202 can be fine-tuned, and then the flipping angle of the lens carrier can be fine-tuned to achieve accurate flipping of the lens carrier.

[0040] Please continue to refer to Figure 1 A second buffer 520 is provided on the flip driving cylinder 500 and adapted to the position of the driving slider 202. The second buffer 520 is used to stop and buffer the driving slider 202. When the output end of the flip driving cylinder 500 extends, the first buffer 510 stops and buffers the driving slider 202 at the end of its stroke. When the output end of the flip driving cylinder 500 contracts, the second buffer 520 stops and buffers the driving slider 202 at the end of its stroke. Through the cooperation of the first buffer 510 and the second buffer 520, the driving slider 202 can be stopped smoothly, so that the lens carrier can be flipped smoothly.

[0041] Please refer to Figure 1In some application examples, a first supporting wheel 221 is rotatably mounted on the first clamping arm 200. The first supporting wheel 221 is located at the lower side of the first transmission belt 220 and abuts against the first transmission belt 220. The stroke of the flip driving cylinder 500 is different according to the size of the lens carrier. The larger the stroke of the flip driving cylinder 500, the larger the span of the first transmission belt 220. After long-term use, the lower part of the first transmission belt 220 collapses due to gravity, causing the first transmission belt 220 to relax. For this reason, arranging the first supporting wheel 221 at the lower side of the first transmission belt 220 can provide a certain fulcrum for the first transmission belt 220, so that the first transmission belt 220 remains taut, which is beneficial to improving the reliability of the transmission.

[0042] Please refer to Figure 2 In other application examples, a second support wheel 321 is rotatably mounted on the second clamping arm 300. The second support wheel 321 is located at the lower side of the second transmission belt 320 and abuts against the second transmission belt 320. Similar to the function of the first support wheel 221, the second support wheel 321 is used to provide a fulcrum for the second transmission belt 320, thereby improving the reliability of transmission.

[0043] Please refer to Figure 1 and Figure 2 In some other application examples, a first support wheel 221 is rotatably mounted on the first clamping arm 200, and a second support wheel 321 is rotatably mounted on the second clamping arm 300. The first transmission belt 220 is supported by the first support wheel 221, and the second transmission belt 320 is supported by the second support wheel 321, which is beneficial to improving the reliability of transmission.

[0044] Please refer to Figure 2 The first clamping arm 200 and the second clamping arm 300 form a first acute angle with the longitudinal plane (eg Figure 2 The angle shown by the mark a) can make it easier for the first clamping jaw 210 and the second clamping jaw 310 to approach the lens carrier on the conveying line, thereby clamping the lens carrier.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
