DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] In the related art, the mechanisms for gluing and laminating are usually arranged on the same moving mechanism, and the mechanism for controlling the flipping of the lens is arranged on the laminating station. The actions of gluing and moving the lens need to be performed sequentially, resulting in a problem of low laminating efficiency.

[0030] In order to solve the above technical problems, this embodiment provides a lens dispensing and pressing device, please refer to Figures 1 to 3 As shown, Figure 1 It is a three-dimensional diagram of the lens dispensing and pressing device in the embodiment, Figure 2 It is a top view of the lens dispensing and pressing device in the embodiment, Figure 3 It is a front view of the lens dispensing and pressing device in the embodiment.

[0031] The lens dispensing and pressing device of the present embodiment comprises: a machine platform 1, a suction cup 2, a turning mechanism 3, a suction cup driving mechanism 4, a dispensing mechanism 5 and a dispensing driving mechanism 6.

[0032] The machine 1 is provided with at least two positioning jigs 8 for placing and positioning the lens 7; the suction cup 2 is movably arranged above the positioning jig 8, and is used to absorb the lens 7 on the positioning jig 8; the flipping mechanism 3 is connected to the suction cup 2, and is used to drive the suction cup 2 and the lens 7 on the suction cup 2 to flip around the horizontal axis; the suction cup driving mechanism 4 is arranged on the machine 1, and is connected to the flipping mechanism 3, and is used to drive the flipping mechanism 3 and the suction cup 2 to rise and fall and move in a horizontal direction, so that the suction cup 2 can move between the two positioning jigs 8; the glue dispensing mechanism 5 is movably arranged above the positioning jig 8, and is used to set glue on the lens 7; the glue dispensing driving mechanism 6 is connected to the glue dispensing mechanism 5, and is used to drive the glue dispensing mechanism 5 to rise and fall and move in a horizontal direction, so that the glue dispensing mechanism 5 can move to be directly above the lens 7.

[0033] When the lens 7 dispensing and pressing device of the above technical solution is working, the lens 7 is placed respectively by two positioning jigs 8, so as to realize efficient dispensing and pressing operations. Specifically, the suction cup driving mechanism 4 drives the suction cup 2 to first move to the top of the first positioning jig 8, accurately suck the lens 7, and then move up and flip it, so that the pressing surface of the lens 7 faces upward. In this process, the dispensing driving mechanism 6 simultaneously drives the dispensing mechanism 5 to move to the top of the second positioning jig 8 to apply glue to the second lens 7. Subsequently, the suction cup 2 moves to the bottom of the dispensing mechanism 5 with the flipped lens 7, and the dispensing mechanism 5 quickly applies glue to the first lens 7. Then, the dispensing mechanism 5 moves away from the top of the second positioning jig 8, and the flipping mechanism 3 drives the suction cup 2 to flip again, so that the pressing surface of the first lens 7 is accurately aligned with the second lens 7. Under the control of the suction cup driving mechanism 4, the first lens 7 is accurately pressed with the second lens 7. Finally, each mechanism automatically resets to prepare for the next lens 7 pressing process. It can be seen that the independent driving design of the suction cup 2 and the glue dispensing mechanism 5 of the above technical solution realizes the parallel operation of sucking, flipping, moving and gluing the lens 7, which greatly shortens the overall time of gluing and pressing the lens 7. Compared with the serial operation of gluing and moving the lens 7 in the traditional technology, it can effectively shorten the time of gluing and pressing the lens 7 and improve the pressing efficiency of the lens 7.

[0034] In one embodiment of the above suction cup driving mechanism 4, see Figure 1 and Figure 3 As shown, the suction cup driving mechanism 4 includes a first moving mechanism 41 and a first lifting mechanism 42 which are connected to each other. The first lifting mechanism 42 is connected to the flipping mechanism 3 and is used to drive the flipping mechanism 3 and the suction cup 2 to move up and down. The first moving mechanism 41 is arranged on the machine platform 1 and is connected to the first lifting mechanism 42, and is used to drive the first lifting mechanism 42, the flipping mechanism 3 and the suction cup 2 to move in the horizontal direction.

[0035] In another embodiment of the above-mentioned suction cup driving mechanism 4, the suction cup driving mechanism 4 includes a first moving mechanism 41 and a first lifting mechanism 42 which are connected to each other, but the first lifting mechanism 42 is arranged on the machine platform and is connected to the first moving mechanism 41, and is used to drive the first moving mechanism 41, the flipping mechanism 3 and the suction cup 2 to move vertically.

[0036] Similarly, in one embodiment of the above-mentioned dispensing drive mechanism 6, refer to Figure 1 and Figure 3 As shown, the glue dispensing drive mechanism 6 includes a second lifting mechanism 61 and a second moving mechanism 62 that are connected to each other.

With such a configuration, different positioning grooves 81 can be placed in lenses 7 of corresponding sizes, and the positioning grooves 81 can position lenses 7 of different sizes, thereby improving the applicability of the positioning jig 8 to lenses 7 of different sizes.

[0042] The shape of the positioning groove 81 can be set according to the shape of the lens 7. For example, see Figure 2 As shown, the lens 7 is circular, and the groove surface of the positioning groove 81 is in an arc shape that matches the shape and size of the lens 7. The groove surfaces of the positioning grooves 81 are concentrically arranged.

[0043] In order to facilitate the taking and placing of the lens 7 in the positioning groove 81, refer to Figure 1 and Figure 2 As shown, the positioning fixture 8 includes at least two positioning parts 83 , a notch 84 for taking and placing the lens 7 is provided between two adjacent positioning parts 83 , and a step structure 82 is provided respectively, and the lens 7 is limited between the step structures 82 of each positioning part 83 .

[0044] For example, see Figure 1 and Figure 2 As shown, four positioning portions 83 are provided, and the interval between two adjacent positioning portions 83 is 90°.

[0045] In order to prevent the glue missed by the dispensing mechanism 5 from polluting the environment of the machine 1, a leak-proof cylinder 10 is also provided on the machine 1. Figure 1 and Figure 3 As shown, the leak-proof cylinder 10 is arranged below the glue dispensing mechanism 5 and is used to receive the glue missed by the glue dispensing mechanism 5 .

[0046] Exemplarily, the leak-proof tube 10 is disposed directly below the initial position of the glue dispensing mechanism 5 .
