[0036] Embodiment 1

[0037] The present embodiment provides a flow coating conveyor line, which realizes the posture switching of the lens, thereby ensuring the uniformity of the flow coating film thickness on the lens. Compared with the posture switching method of the traditional robotic arm, it can effectively reduce the cost, reduce the space occupied by the lens during the flow coating process, and flip the lens at a uniform and stable speed. It also has a simple structure, is more practical, and can be quickly dismantled for inspection and maintenance.

[0038] Combination Figures 1 to 5As shown, the flow coating conveying line of the present embodiment includes a flow coating conveying track 10, a driving unit 20, a flow coating support 30, a carrier unit 40 and a guide rod 50. The number of the flow coating conveying tracks 10 of the present embodiment is four and they are interconnected to form a continuous closed track to meet the continuous flow coating treatment of the lens. The number of the driving units 20 is four groups, which are respectively located between two adjacent flow coating conveying tracks 10 to connect and drive the adjacent flow coating conveying tracks 10. The driving unit 20 of the present embodiment is divided into an active part and a driven part. One group of driving units 20 is used as an active part, and the other driving units 20 are used as driven parts. The active part is actively driven, and the driven part plays a transmission role.

[0039] In the present embodiment, a transmission chain 11 is provided in the flow coating conveying track 10, and the transmission chains 11 in adjacent flow coating conveying tracks 10 are connected. The number of transmission chains 11 in the present embodiment is four groups and they are interconnected to form a continuous transmission structure, and the driving part 20 of the present embodiment includes a driver 21 and a transmission gear 22, the transmission gear 22 is connected to the driver 21 through a reducer, and the transmission gear 22 is meshed with the transmission chain 11 to drive the transmission chain 11. The driver 21 of the present embodiment is a driving motor, and the driving motor drives the transmission gear 22 through the reducer. Since the transmission gear 22 is meshed with the transmission chain 11, the transmission chain 11 will continue to transmit, driving the flow coating bracket 30 to transmit, so as to carry out flow coating treatment of the lens.

[0040] Furthermore, the flow coating conveyor line of the present embodiment also includes a frame 70, and the flow coating conveyor track 10, the driving unit 20 and the guide rod 50 are all installed on the frame 70. A plurality of receiving plates 80 are arranged on the frame 70, and the receiving plates 80 are located below the flow coating conveyor track 10. During the flow coating process of the lens, material dripping will occur, so the receiving plates 80 can collect the material to reduce the loss cost.

[0041] Combination Figure 3 and Figure 4 As shown, the number of flow coating brackets 30 of this embodiment is several and they move along the length direction of the flow coating conveying track 10. The carrier part 40 is rotatably installed on the flow coating bracket 30. The carrier part 40 includes a rotating block 41, a deflection guide wheel 42 and a flow coating member 43. The deflection guide wheel 42 and the flow coating member 43 are respectively located at both ends of the rotating block 41. The flow coating bracket 30 of this embodiment is installed on the transmission chain 11. When the transmission chain 11 continues to transmit under the driving action of the driving part 20, it will drive the flow coating bracket 30 to move, and the carrier part 40 is rotatably installed on the flow coating bracket 30. The flow coating member 43 is a lens. When the carrier part 40 follows the flow coating bracket 30 to move, the lens will be flow coated, and the movement posture of the lens can also be changed, thereby meeting the flow coating requirements of the lens and improving the flow coating effect.

[0042] Specifically, the flow coating bracket 30 of the present embodiment is an L-shaped structure, the short side of the flow coating bracket 30 is installed on the transmission chain 11, and the rotating block 41 is installed on the long side of the flow coating bracket 30. The L-shaped flow coating bracket 30 is used to ensure the flow coating effect on the lens, while being conducive to adjusting the movement posture of the lens and saving space.

[0043] In this embodiment, the rotating block 41, the deflection guide wheel 42 and the flow coating member 43 are fixedly connected, and the rotating block 41 is installed on the flow coating bracket 30 through the rotating shaft 60. When the deflection guide wheel 42 changes its movement posture, the flow coating member 43 switches between the horizontal posture and the vertical posture. When the deflection guide wheel 42 deflects, the flow coating member 43 will also deflect, thereby changing the movement posture of the flow coating member 43, so that the flow coating member 43 switches between the horizontal posture and the vertical posture, satisfying the flow coating treatment of the lens.

[0044] Combination Figure 3 and Figure 5 As shown, the guide rod 50 of this embodiment is located below the flow coating conveying track 10. The guide rod 50 is a continuously bent structure. The guide rod 50 changes the movement posture of the deflection guide wheel 42, and changes the movement posture of the flow coating member 43 through the rotating block 41. The guide rod 50 of this embodiment is fixedly installed below the flow coating conveying track 10. When the deflection guide wheel 42 contacts the guide rod 50, since the guide rod 50 is a continuously bent structure, the movement posture of the deflection guide wheel 42 will change according to the bending condition of the guide rod 50, and the rotating block 41 of this embodiment 41. The deflection guide wheel 42 and the flow coating member 43 are fixedly connected. Therefore, when the movement posture of the deflection guide wheel 42 changes, under the action of the rotating block 41, the movement posture of the flow coating member 43 will also change accordingly. In actual use, the flow coating member 43 will switch between the horizontal posture and the vertical posture, thereby meeting the flow coating processing requirements of the lens. The deflection guide wheel 42 of this embodiment is provided with a notch, and the notch is in contact with the surface of the guide rod 50. Therefore, the deflection guide wheel 42 can be in stable contact with the guide rod 50 to achieve a stable change of the movement posture.

[0045] In this embodiment, the guide rod 50 includes a front end rod 51, a middle end rod 52 and a rear end rod 53 which are arranged in sequence. The front end rod 51, the middle end rod 52 and the rear end rod 53 are integrally formed. When the flow coating support 30 moves along the length direction of the flow coating conveying track 10, the deflection guide wheel 42 contacts the guide rod 50 and moves along the length direction of the guide rod 50. When the deflection guide wheel 42 moves along the length direction of the front end rod 51, the flow coating member 43 is in a horizontal posture. When the deflection guide wheel 42 moves along the length direction of the middle end rod 52, the flow coating member 43 is in a horizontal posture. Vertical posture, when the deflection guide wheel 42 moves along the length direction of the rear end rod 53, the flow coating piece 43 is in a horizontal posture. Therefore, during the movement of the flow coating bracket 30, the flow coating piece 43 of this embodiment appears in a horizontal posture-vertical posture-horizontal posture in sequence. The guide rod 50 includes a front end rod 51, a middle end rod 52 and a rear end rod 53, which can continuously adjust the posture of the flow coating piece 43. According to the needs of posture adjustment, replacing the guide rod 50 of different shapes can meet the posture adjustment needs of the lens, and then meet the flow coating needs of the lens.

[0046] In actual use, the flow coating conveyor line of this embodiment is provided with a transmission chain 11 in the flow coating conveying track 10, and a closed and continuous transmission structure is formed by the transmission chain 11, and the transmission structure is driven by the driving unit 20, and the flow coating bracket 30 is installed on the transmission chain 11, the guide rod 50 is installed below the flow coating conveying track 10, and the carrier unit 40 is installed on the flow coating bracket 30. When the flow coating bracket 30 moves following the transmission chain 11, the deflection guide wheel 42 of the carrier unit 40 will continue to contact with the guide rod 50. Since the guide rod 50 is a continuous bending structure, the movement posture of the deflection guide wheel 42 will change, and the rotating block 41, the deflection guide wheel 42 and the flow coating member 43 are fixedly connected. Therefore, when the movement posture of the deflection guide wheel 42 changes, the movement posture of the flow coating member 43 will also change, which is specifically presented as horizontal posture-vertical posture-horizontal posture, meeting the flow coating processing requirements for lenses in different postures.

[0047] Embodiment 2

[0048] like Figure 6 As shown, this embodiment provides a flow coating delivery method, comprising the following steps:

[0049] S1, the deflection guide wheel 42 and the flow coating member 43 are respectively installed at both ends of the rotating block 41, and then the rotating block 41 is installed on the flow coating bracket 30. At this time, the flow coating member 43 is in a horizontal posture. The rotating block 41, the deflection guide wheel 42 and the flow coating member 43 of this embodiment are fixedly connected. Therefore, when the deflection guide wheel 42 changes its motion posture, the motion posture of the flow coating member 43 will change under the cooperation of the rotating block 41, thereby meeting the flow coating requirements of the flow coating member 43;

[0050] S2, the driving unit 20 drives the transmission chain 11, and the transmission chain 11 drives the flow coating bracket 30 to move during the transmission process, so that the flow coating bracket 30 moves along the length direction of the flow coating conveying track 10, and the flow coating bracket 30 drives the carrier unit 40 to move, so as to adjust the movement posture of the flow coating member 43 later;

[0051] S3. During the movement of the flow coating bracket 30, the deflection guide wheel 42 passes through the front end rod 51, the middle end rod 52 and the rear end rod 53 of the guide rod 50 in sequence, and the deflection guide wheel 42 moves in contact with the guide rod 50. The deflection guide wheel 42 changes its movement posture under the action of the guide rod 50, and switches the flow coating part 43 between the horizontal posture and the vertical posture. The guide rod 50 of this embodiment includes the front end rod 51, the middle end rod 52 and the rear end rod 53. During the continuous movement of the deflection guide wheel 42, the deflection guide wheel 42 is in continuous contact with the guide rod 50, thereby realizing the adjustment of the posture of the flow coating part 43. According to the requirements of posture adjustment, replacing the guide rod 50 with different shapes can meet the posture adjustment requirements of the lens, and then meet the flow coating requirements of the lens.

[0052] In this embodiment, the flow coating member 43 is a lens, and the flow coating delivery method can be used to adjust the movement posture of the lens, so that the lens appears in horizontal posture-vertical posture-horizontal posture in sequence, thereby meeting the flow coating processing requirements of the lens in different postures.
