[0028] Example 1:

[0029] Please see Figure 1-4 A lens coating apparatus, comprising:

[0030] The liquid storage tank 1 has multiple mounting brackets 2 fixedly connected to its top, and a lower support plate 3 fixedly connected between the multiple mounting brackets 2. A support plate 4 is fixedly connected to one side of the lower support plate 3.

[0031] The transmission screw 5 is vertically rotatably connected inside the support plate 4. The top of the support plate 4 is fixedly connected to the transmission motor 6, and the output end of the transmission motor 6 is fixedly connected to the transmission screw 5. The outer side of the transmission screw 5 is threadedly connected to the displacement plate 7, and one end of the displacement plate 7 is fixedly connected to the upper bearing plate 8.

[0032] The liquid supply assembly 9 and the displacement plate 7 are assembled between the lower support plate 3 and the upper support plate 8, and are used to apply coating liquid to the bottom and top surfaces of the lens.

[0033] In this embodiment, multiple receiving grooves 10 are provided at the top of the lower support plate 3 and the bottom of the upper support plate 8, and each receiving groove 10 is provided with a coating liquid flow channel. By setting the receiving grooves 10, after the upper support plate 8 is lowered to the top of the lower support plate 3, the lens can be limited between the two corresponding receiving grooves 10, so as to avoid uncontrollable movement of the lens during coating.

[0034] In this embodiment, a liquid level feedback window is provided on one side of the liquid storage tank 1. A transparent sealing plate is fixedly connected inside the liquid level feedback window. Through the setting of the liquid level feedback window, the remaining amount of coating liquid in the liquid storage tank 1 can be intuitively fed back. In addition, an addition tube is fixedly connected to the top of the liquid storage tank 1. A sealing cap is threaded onto the addition tube. Through the setting of the addition tube, the coating liquid can be conveniently added to the liquid storage tank 1.

[0035] In this embodiment, a linear guide rod is vertically fixedly connected to the inner side of the support plate 4, and the displacement plate 7 is also slidably connected to the outer side of the linear guide rod. By setting the linear guide rod, the displacement of the displacement plate 7 can be assisted and limited, preventing the displacement plate 7 from rotating with the transmission screw 5, thereby ensuring the stability of the displacement plate 7 in application.

[0036] In this embodiment, sealing strips are fixedly connected to the top edge of the lower support plate 3 and the bottom edge of the upper support plate 8. By setting the sealing strips, after the lower support plate 3 and the upper support plate 8 come into contact, the connection gap between the lower support plate 3 and the upper support plate 8 can be reduced by the sealing strips, so as to prevent the coating liquid from overflowing from the connection gap between the lower support plate 3 and the upper support plate 8.

[0037] Example 2:

[0038] Please see Figure 1-4 This embodiment provides a technical solution based on Embodiment 1: In this embodiment, the liquid supply component 9 includes:

[0039] An external pump 11 is fixedly connected to one side of the liquid storage tank 1. An external pipe 12 is fixedly connected to the input end of the external pump 11, and the end of the external pipe 12 away from the external pump 11 is connected to the liquid storage tank 1. A transmission pipe 13 is fixedly connected to the output end of the external pump 11.

[0040] Diverter pipe 14 is fixedly connected to one end of lower support plate 3. Positioning frame 15 is fixedly connected to the bottom end of lower support plate 3 and the top end of upper support plate 8. Liquid distribution pipe 16 is fixedly connected to the positioning frame 15. Liquid supply pipe 17 corresponding to the coating liquid flow channel is fixedly connected to the outside of liquid distribution pipe 16. The end of liquid supply pipe 17 away from liquid distribution pipe 16 is connected to the corresponding coating liquid flow channel. One end of each of the two liquid distribution pipes 16 is fixedly connected to a delivery pipe 18. The ends of the two delivery pipes 18 away from liquid distribution pipe 16 are respectively connected to the two ends of the diverter pipe 14.

[0041] In this embodiment, two positioning ears are fixedly connected to one end of the lower support plate 3, and the diversion pipe 14 is fixedly connected between the two positioning ears. By setting the positioning ears, the diversion pipe 14 can be stably supported, and the diversion pipe 14 can be prevented from shaking violently during the diversion process.

[0042] In this embodiment, a solenoid valve is provided at one end of the liquid distribution pipe 16 near the delivery pipe 18. The solenoid valve can be used to close the liquid distribution pipe 16 when it is not in use. The delivery pipe 18 is made of flexible material. Through the structural characteristics of the delivery pipe 18, the coating liquid transmission effect can be guaranteed, and the displacement of the upper support plate 8 will not be interfered with.

[0043] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0044] Working principle: First, the lens is placed in the receiving groove 10 of the lower support plate 3. Then, the drive motor 6 is started to drive the drive screw 5 to rotate. With the connection between the drive screw 5 and the displacement plate 7, the displacement plate 7 can drive the upper support plate 8 to move vertically along the drive screw 5 until the upper support plate 8 contacts the lower support plate 3, and finally the lens is loaded between the two corresponding receiving grooves 10.

[0045] The external pump 11 is started to draw the coating solution inside the storage tank 1 through the external pipe 12, and then through the transmission pipe 13 to the diversion pipe 14. It is then injected into the two diversion pipes 16 through the delivery pipe 18. The coating solution inside the diversion pipe 16 is applied to the top and bottom of the lens through the supply pipe 17, so as to simultaneously perform coating operations on multiple sides of the lens, which greatly improves the overall coating efficiency.
