DETAILED DESCRIPTION

[0034] The technical features of the present invention are further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand them.

[0035] An automatic lens cleaning machine comprises a frame 1, a first track plate 6 is arranged above the frame 1, a second track plate 7 is arranged below the first track plate 6, a first crank slider mechanism 2 is arranged on the first track plate 6 for driving the second track plate 7 to move horizontally left and right along the first track plate 6, a frame device 4 is arranged below the second track plate 7, a second crank slider mechanism 3 is arranged on the second track plate 7 for driving the frame device 4 to move horizontally forward and backward, the frame device 4 comprises a frame plate 401, a vertical guide column 407, an upper brush plate mounting plate 402 arranged below the frame plate 401 and capable of being raised and lowered along the vertical guide column 407, and a lower brush plate mounting plate 403. A mounting plate 403 is provided on the frame plate 401 with a first lifting cylinder 404 for driving the upper brush plate mounting plate 402 to rise and fall, and a second lifting cylinder 405 for driving the lower brush plate mounting plate 403 to rise and fall, a ring 406 for loading a number of lenses and being clamped by the upper brush plate mounting plate 402 and the lower brush plate mounting plate 403 for washing is provided between the upper brush plate mounting plate 402 and the lower brush plate mounting plate 403, an upper brush plate 8 is detachably mounted on the upper brush plate mounting plate 402, and a lower brush plate 9 is detachably mounted on the lower brush plate mounting plate 403, and both the upper brush plate 8 and the lower brush plate 9 are provided with a spray hole 10 for connecting to a water pipe for spraying cleaning agent on the lenses.

[0036] Because the frame device 4 also moves together with the second track plate 7, the forward and backward movement of the frame device 4 plus the left and right movement of the second track plate 7 means that the frame device 4 actually moves in a circular arc.

[0037] When only the first motor 201 is turned on, the frame device 4 moves back and forth along with the second track plate 7 . When only the second motor 301 is turned on, the frame device 4 moves back and forth.

[0038] The function of the frame device 4 is to clamp the lens on the ring 406 by lifting the upper brush plate 8 and the lower brush plate 9, and to scrub the lens sprayed with the cleaning agent by moving forward and backward, left and right, or in an arc shape, so as to complete the automatic cleaning of the lens. The ring 406 can be loaded with lens plates of different sizes, and the lens plates can also be loaded with lenses of different shapes, so the device can clean various lenses, has a wide range of applications, and can greatly improve the cleaning efficiency and quality.

[0039] Of course, it can also be arranged that the second track plate 7 moves forward and backward, and the frame device 4 moves left and right.

[0040] like Figure 3 and Figure 4 It can be seen that the first lifting cylinder 404 pushes the upper brush plate mounting plate 402 to move up and down, and the second lifting cylinder 405 pulls the lower brush plate mounting plate 403 to move up and down. The first lifting cylinder 404 pushes the upper brush plate mounting plate 402 to move up and down, and the second lifting cylinder 405 pulls the lower brush plate mounting plate 403 to move up and down.

[0041] The first lifting cylinder 404 and the second lifting cylinder 405 are both pen-shaped cylinders, and there are screws on the top of the pen-shaped cylinders to adjust the stroke of the piston rod and thus adjust the clamping degree of the ring 406 to ensure that there is no relative movement between the brush plate and the brush plate mounting plate when washing the lens.

[0042] Because the entire frame device 4 needs to move horizontally, the bottom of the frame device 4 is suspended and does not contact the frame 1. In this application, a large hole is opened on the frame plate to allow the bottom of the frame device 4 to extend into the frame, thereby reducing the overall height of the equipment and saving materials.

[0043] Furthermore, a first bracket 14 is provided on the frame 1, and the first track plate 6 is supported by the first bracket 14. A track for the second track plate 7 to be used in the left-right direction is provided at the bottom of the first track plate 6, and a track for the frame plate 401 to be used in the front-back direction is provided at the bottom of the second track plate 7; the first crank slider mechanism 2 includes a first motor 201 fixed on the first track plate 6, a first crank 202 driven to rotate by the output shaft of the first motor 201, and a first connecting rod 203 driven to rotate by the first crank 202, and the second track plate 7 is hinged to the other end of the first connecting rod 203; the second crank slider mechanism 3 includes a second motor 301 provided on the first track plate 6, a second crank 302 driven to rotate by the output shaft of the second motor 301, and a second connecting rod 303 driven to rotate by the second crank 302, and the frame plate 401 is hinged to the other end of the second connecting rod 303.

[0044] The first slider crank mechanism 2 converts the rotation of the first motor 201 into the front-rear reciprocating motion of the second track plate 7 , and the second slider crank mechanism 3 converts the rotation of the second motor 301 into the left-right reciprocating motion of the frame plate 401 .

[0045] like Figure 5 As shown, steps are provided on both sides of the upper brush plate 8 and the lower brush plate 9, and the upper brush plate mounting plate 402 and the lower brush plate mounting plate 403 are provided with a clamping strip 11 for clamping the steps. The upper brush plate 8 and the lower brush plate 9 are detachably mounted, and the structure is simple and convenient to use. When in use, the upper brush plate 8 and the lower brush plate 9 can be directly pushed in, and the upper brush plate 8 is hung on the upper brush plate mounting plate 402 for use.

[0046] In addition, a pushing device 5 for automatically pushing the collar 406 is provided on the frame 1 , and a cleaning agent recycling device is provided below the frame 1 .

[0047] The pushing device 5 includes a first driving cylinder 501 arranged on the second bracket, a horizontal guide column 502, and a slider 503 driven by the first driving cylinder 501 to move horizontally along the horizontal guide column 502, and the ring 406 is placed on the slider 503 and fixed by bolts.

[0048] The first driving cylinder 501 is provided with one on each side, and a handle is provided on the collar 406 to facilitate pushing and pulling the collar 406. Various types of holes are provided on the collar 406 to facilitate loading different types of lens plates. The lens plate is provided with several lenses, which has a wide range of applications.

[0049] The cleaning agent recycling device includes a first filter bucket 12 and a cleaning agent storage box arranged below the frame 1. A water pump is arranged in the cleaning agent storage box to pump the filtered cleaning agent to the upper brush plate mounting plate 402 and the lower brush plate mounting plate 403 through a water pipe.

[0050] The automatic lens cleaning machine as described above is also provided with a second filter hopper 13 for drying the cleaned lenses on the frame 1. The cleaned lens plate is manually transferred to the second filter hopper 13 hung on the side for drying, and the dripping cleaning agent is filtered by the second filter hopper 13 and then flows back to the cleaning agent storage box, and can be pumped up and reused next time.

[0051] The automatic lens cleaning machine as described above is provided with a distribution box on the frame 1 and above the first track plate 6, which is not shown in the figure.

[0052] In the above-mentioned automatic lens cleaning machine, the frame device 4, the first track plate 6, and the second track plate 7 are all made of corrosion-resistant stainless steel. Since the cleaning agent is corrosive, aluminum alloy cannot be used. In this application, chrome is plated on the surface of the stainless steel to prevent corrosion. Multiple holes are opened on the second track plate 7, the frame plate 401, the upper brush plate mounting plate 402, and the lower brush plate mounting plate 403 to reduce weight, materials, and costs.

[0053] The present invention also seeks to protect a method for cleaning lenses using the above-mentioned automatic lens cleaning machine, which comprises the following steps:

[0054] A. Manually push the upper brush plate 8 into the upper brush plate mounting plate 402, push the lower brush plate 9 into the lower brush plate mounting plate 403, and connect the upper brush plate mounting plate 402 and the lower brush plate mounting plate 403 to the water pipe;

[0055] B. Manually load multiple lens plates onto the collar 406, with multiple lenses placed on the lens plates;

[0059] F. The cleaning agent in the cleaning agent storage tank is pumped by the water pump along the water pipe and the injection hole 10 to the lens;

[0060] G. The first crank slider mechanism 2 drives the upper brush plate 8 and the lower brush plate 9 to simultaneously make left-right reciprocating motions to clean the lens for several times. The second crank slider mechanism 3 drives the upper brush plate 8 and the lower brush plate 9 to simultaneously make front-back reciprocating motions to clean the lens for several times. The first crank slider mechanism 2 and the second crank slider mechanism 3 are started to drive the upper brush plate 8 and the lower brush plate 9 to simultaneously make arc motions to clean the lens for several times.

[0061] H. After cleaning is completed, reset the upper brush plate mounting plate 402 and the lower brush plate mounting plate 403;
