[0033] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Example 1

[0036] This invention provides a detection system for optical lenses. As one specific embodiment, refer to... Figure 1 The system includes:

[0037] Material tray 1, horizontally set, is used to hold optical lenses for testing;

[0038] The receiving hopper 2 is located below the loading tray 1;

[0039] The abrasive circulation device 3 includes a discharge port 31 disposed above the material carrier plate 1, a feed port 32 disposed on the receiving hopper 2, and an abrasive pumping device 33 disposed between the feed port 32 and the discharge port 31.

[0040] Specifically, when testing the abrasion resistance of a lens, the lens to be tested is placed on the carrier tray 1, and the abrasive circulation device 3 is activated to circulate and supply abrasive placed in the receiving hopper. The abrasive is discharged from the outlet 31 and falls onto the lens on the carrier tray under the action of gravity, which plays a frictional role on the lens surface. After passing the lens, the abrasive falls into the receiving hopper below and participates in the circulation again, thereby continuously supplying abrasive to the lens. After a certain period of time, the lens is removed, and the scratches on the lens surface are observed through a microscope to understand the degree of wear of the lens and obtain the abrasion resistance of the lens. The friction effect obtained in this way is similar to the friction effect in daily use, which can better simulate the wear effect of the lens in daily use. The abrasive can be selected from abrasives such as diamond with a certain particle size. The carrier tray 1 can be equipped with a rubber suction cup on the upper surface to adsorb and fix the lens. The specific structure and working method of the abrasive pumping device 33 are described below.

[0044] Specifically, the principle of reciprocating driving of the driving rod is that when the abrasive pumping device 33 pumps the abrasive to circulate and pumps the abrasive out of the discharge port 31, the impeller can be driven to rotate, and the driving rod is driven to move downward.

[0045] Further, as a preferred embodiment, referring to Figure 1 , in order to further improve the uniformity of the optical lens friction and improve the detection efficiency, the system comprises a vertically arranged cylindrical box 5, a load plate 52 is horizontally arranged at the middle position of the box 5, a rotating shaft 53 is vertically arranged at the center of the load plate 52, a rotating disc 54 is arranged at the upper end of the rotating shaft 53, a driving device 55 is connected to the lower end of the rotating shaft, and the load plate 1 is provided in multiple, and the multiple load plates 1 are uniformly and spacedly arranged on the rotating disc 54 around the rotating shaft 53.

[0046] Specifically, referring to Figure 1 , through this arrangement, during operation, the rotating disc 54 can be driven to rotate by the driving device 55, thereby driving the load plate to rotate, and the optical lens arranged on the load plate can rotate around the rotating shaft 53, so that the lens can pass through each distribution area, and the abrasive falling on the lens is more uniform, thereby improving the uniformity of friction

[0047] Further, as a further improvement, referring to Figure 1 , the rotating disc 54 is arranged spacedly from the upper surface of the load plate 52, the upper surface of the load plate 52 is coaxially arranged with the annular gear ring 521 of the rotating shaft 53, the second rotating shaft 12 corresponding to the load plate 1 is arranged rotatingly on the rotating disc 54, the lower end of the second rotating shaft 12 is arranged with a driven gear 13 engaged with the annular gear ring 521, and the load plate 1 is arranged at the upper end of the second rotating shaft 12. In this way, while the rotating disc 54 is driven to rotate, the second rotating shaft can also rotate, thereby driving the load plate to rotate, so that the load plate can rotate around the rotating shaft while rotating itself, thereby further improving the uniformity of friction between the lens and the abrasive.

[0048] Further, referring to Figure 1 , as a specific embodiment, the rotating disc 54 is circularly arranged, and the upper surface is arranged as a spherical surface protruding upward, the edge of the rotating disc 54 extends downward to be arranged with an annular skirt 541, the load plate 52 is arranged with an annular baffle 523 slidingly matched with the skirt 541, and a plurality of leakage holes 522 are arranged spacedly on the load plate 52 outside the annular baffle and around the annular baffle.

[0049] Further, as a preferred embodiment, referring to Figure 1The carrier plate 52 is horizontally slidably arranged in the columnar box 5. An opening 50 is arranged on one side of the columnar box 5 for the carrier plate 52 to slide out. A sealing surface 501 is arranged at the opening 50. An end plate 524 is connected to the carrier plate 52. When the carrier plate 52 is completely arranged in the columnar box 5, the end plate 524 is in sealing cooperation with the sealing surface 501. Specifically, referring to Figure 1 、 Figure 2 The columnar box 5 is preferably a box with a rectangular cross section. Guide rails (not shown in the figure) are horizontally arranged on the inner walls of the opposite sides of the box to guide the sliding of the carrier plate. In this way, the carrier plate 52 can be horizontally slidably arranged in the columnar box 5.

Then, the abrasive circulating device 3 is started to test the optical lens. After the test is completed, the carrier plate is horizontally slid out, which is convenient for taking and placing the optical lens. Further, as a preferred embodiment, a handle 5241 is arranged on the end plate 524 to facilitate the sliding of the carrier plate 52.

[0050] Further, it can be understood that when the system is working, the abrasive is pumped by the abrasive circulating device.

The locking assembly is used to lock the carrier plate 52 and the columnar box 5 when the abrasive pumping device 33 is working. The carrier plate is locked when the system is working and is released when the system is stopped, so that the carrier plate can be prevented from being mistakenly pulled out.

The side surface of the positioning block close to the opening 50 is a first inclined surface 610 arranged obliquely away from the opening. Specifically, referring to Figure 1 、 Figure 3The working principle of the locking assembly is that when the abrasive pumping device is not working, the limiting block 63 is below the positioning block 61 and is spaced apart from the positioning block, at this time, the limiting block and the positioning block are not coincident in the horizontal direction, and the carrier plate can slide freely in the horizontal direction; when the abrasive pumping device is working, the rigid rod 62 extends upward, thereby driving the limiting block 63 to extend upward, so that the limiting block can provide a thrust to the positioning block through the first inclined surface 610 in the direction away from the outlet 50, so that the end plate can be more closely attached to the sealing surface 501, and at the same time, the positioning block 61 is limited, so as to achieve the purpose of limiting the carrier plate 52; when the abrasive pumping device stops working again, the rigid rod moves to the initial position in the direction away from the positioning block 61, and the positioning block 61 is released. Specifically, the driving mode of the rigid rod is described below.

[0052] Further, as a specific embodiment, refer to Figure 1 The pumping device 33 comprises a discharge pipe 331 vertically arranged at the feeding port 32, a conveying pipe 332 communicated to the lower end of the discharge pipe 331, and a pump gas device 333 arranged at one end of the conveying pipe 332, and the other end of the conveying pipe is communicated to the discharge port 31. Specifically, by this arrangement, when the pump gas device 333 works, gas is pumped into the conveying pipe 332, the gas flows rapidly in the conveying pipe and then is pumped out from the discharge port 31, and a certain negative pressure can be generated in the discharge pipe 331, so that the abrasive collected in the collecting hopper 2 can be pumped into the conveying pipe along with the gas flow under the action of gravity and negative pressure and then be pumped to the discharge port 31, thereby realizing the pumping effect.

[0053] Further, as a specific embodiment, refer to Figure 1 、 Figure 13 The locking assembly 6 further comprises a first piston cavity 60 vertically arranged on the cylindrical box 5, a first piston plate 64 movably arranged in the first piston cavity 60, and the rigid rod 62 is arranged on the side of the first piston plate 64 close to the positioning block 61. One end of the first piston cavity 60 close to the positioning block is communicated to the conveying pipe 332 through a first rigid gas conveying pipe 641, and the other end of the first piston cavity 60 away from the positioning block is communicated to the gas inlet end of the pump gas device 333 through a second gas conveying pipe 642.

[0054] Further, in the actual use process, the system is used for detecting the lens, when the carrier plate slides outwards, because there is a certain abrasive left on the upper surface of the carrier plate, the vibration generated when the carrier plate slides outwards can make the abrasive leak, so that part of the abrasive flows out of the cylindrical box, causing waste of the abrasive, in order to avoid or reduce the waste of the abrasive, as a specific embodiment, referring to Figure 1 、 Figure 10 、 Figure 11 , the inner side wall of the upper end cover of the cylindrical box 5 is provided with a second piston chamber 5d opening downward, a cylindrical second material guide pipe 310 is vertically arranged, the discharge port 310 is the lower end opening of the second material guide pipe 310, the second piston 43 movably arranged in the second piston chamber 5d is arranged in the second piston chamber 5d, the second piston is provided with a guide hole in sliding sealing cooperation with the second material guide pipe 310, the lower end of the second material guide pipe 310 is provided with a limiting nut 311, and a seventh compression spring 44 is arranged between the second piston 43 and the bottom of the second piston chamber 5d, the inner side wall of the second piston chamber is axially spaced apart to be provided with a third piston chamber 47 and a vent 5a-1, the third piston chamber 47 is arranged along the radial direction of the second piston chamber and coaxially provided at the bottom with a guide channel 470 communicating with the second piston chamber 5d, the distance d1 from the guide channel to the vent 5a-1 along the axial direction is less than the thickness d2 of the second piston, the third piston 472 is slidably arranged in the third piston chamber 47, the third piston is provided with a third end plug 473 at the opening position, the third piston is provided with a first limiting pin 471, the first limiting pin 471 is guided and matched with the guide channel 470, the ninth compression spring 475 is arranged between the bottoms of the third piston chambers, the side surface of the second piston is provided with a limiting ring groove 431 matched with the first limiting pin, referring to Figure 1, the working area 5c is formed between the upper end surface of the connecting cylinder 4a and the columnar box, the fourth piston cavity 45 is arranged in the working area 5c, the fourth piston 46 is slidably arranged in the fourth piston cavity 45, the fourth piston divides the fourth piston cavity 45 into the fourth piston cavity 45a and the fourth piston cavity 45b, the fourth piston cavity 45b is communicated with the third piston cavity through the third vent pipe 474, the first vent passage 459 and the vent blind hole 453 are arranged on the side wall of the fourth piston cavity 45a, the end of the vent blind hole is provided with a micro vent passage 455 communicated with the working area 5c, the first vent passage is provided with a first one-way valve 4510 allowing the gas to flow into the fourth piston cavity 45a in one direction, the valve passage 452 intersecting with the vent blind hole 453 is further arranged in the side wall of the fourth piston cavity 45a, the opening position of the valve passage is provided with a breathable end plug 458, the bottom of the valve passage is provided with a second valve passage 454 communicated with the atmosphere, the valve rod 456 is arranged in the valve passage, the tenth compression spring 457 is arranged between the bottom of the valve passage and the valve rod 456, the first vent passage 459 is communicated with the vent 5a-1, as a specific embodiment, the micro vent passage 455 is selected with a hole diameter of 0.01-0.1mm, and the second piston 43 is in contact with the limiting nut 311 under the action of the air pressure in the second piston cavity and the elastic force of the seventh compression spring, and the second piston blocks the air passage 5a-1. At this time, the air pressure in the working area 5c is equal to the atmospheric pressure, so the end of the valve rod 456 is in contact with the air permeable end plug 458 under the action of the elastic force of the tenth compression spring 457, the air permeable blind hole 453 is in communication with the working area 5c, the fourth piston is at one end close to the fourth piston cavity 45a, the third piston 472 abuts against the third end plug 473, and the first limiting pin 471 is in the guide channel 470. When the abrasive circulating device 3 is working, the gas with a certain air pressure can be provided to the working area 5c, so that the air pressure P1 in the working area 5c is increased and higher than the external atmospheric pressure, so that the second piston is pushed to move against the air pressure in the second piston cavity and the elastic force of the seventh compression spring 44 under the action of the gas pressure. When the second piston cannot block the air passage 5a-1, the second piston blocks the guide channel 470, at this time, the air passage is in communication with the working area 5c, and the valve rod 456 blocks the air permeable blind hole 453 against the elastic force of the tenth compression spring, so that the air permeable blind hole cannot be ventilated, so that the air pressure in the fourth piston cavity 45a is equal to the air pressure in the working area 5c. At this time, the fourth piston can be pushed to move under the action of the air pressure, and the gas in the fourth piston cavity 45b is extruded, so that the air pressure in the fourth piston cavity 45b is increased, so that the third piston has a tendency to resist the elastic force of the ninth compression spring 475. With the continuous movement of the second piston 43, the limiting ring groove 431 corresponds to the guide channel 470, at this time, the first limiting pin 471 extends into the limiting ring groove to limit the second piston, and the third piston stops moving. After the abrasive circulating device 3 stops working, the air pressure in the working area 5c decreases and gradually equals to the atmospheric pressure. Due to the setting of the first one-way valve 4510, the gas in the fourth piston cavity 45a cannot flow out from the first air passage 459. At this time, the end of the valve rod 456 is in contact with the air permeable end plug 458 under the action of the elastic force of the tenth compression spring 457, the air permeable blind hole 453 is in communication with the working area 5c, so that the gas in the fourth piston cavity 45a can be slowly released through the micro air passage 455, the air pressure in the third piston cavity is reduced, so that the first limiting pin is gradually pulled out of the limiting ring groove 431, and after a predetermined time T, the first limiting pin is completely pulled out of the limiting pin 471, the second piston 43 is released, and the second piston moves downward quickly under the action of the seventh compression spring and the air pressure in the second piston cavity, so that the air pressure in the working area 5c increases rapidly, the gas flow flows out quickly from the leakage hole 410 on the leakage plate, and a certain vibration can be generated. Part of the abrasive remaining on the leakage plate falls under the action of vibration and gas flow, so as to achieve the purpose of cleaning the abrasive remaining on the leakage plate and reducing the loss of abrasive.

[0055] Further, the time length T is preferably 5-15 seconds, and the value of T can be adjusted by controlling the cross-sectional area of the micro air passage 455.

[0056] Further, as a preferred embodiment, the reference Figure 13 、 Figure 14 On the side of the first piston cavity 60 away from the positioning block 61, a fixed plate 65 is arranged, and a guide cylinder 66 is arranged on the fixed plate. A positioning rod 67 is arranged on the first piston plate and guided by the guide cylinder. A fifth piston cavity 661 is arranged on the side wall of the guide cylinder 66. A fifth end plug 663 is arranged at the opening position of the fifth piston cavity. A fourth air pipe 643 is arranged on the fifth end plug and communicates with the second piston cavity 5d. A fifth piston 662 is movably arranged in the fifth piston cavity. A second guide channel is arranged at the bottom of the fifth piston. A second positioning pin 665 is arranged on the fifth piston and guided by the second guide channel. An eleventh compression spring 664 is arranged between the fifth piston and the bottom of the fifth piston cavity. A positioning hole 671 is arranged on the positioning rod 67 and matched with the second positioning pin 665. When the first piston plate moves upward to the position where the limiting block limits the positioning block 61, the second positioning pin corresponds to the positioning hole. In this way, when the abrasive circulating device 3 is not working, the fifth piston is abutted on the fifth end plug under the action of the eleventh spring. At this time, the second positioning pin is within the range of the second guide channel. When the abrasive circulating device 3 works, the air pressure in the second piston cavity is increased. Under the action of the air pressure, the fifth piston has a tendency to move against the elastic force of the eleventh compression spring. When the pressure difference drives the first piston plate 64 to move upward, the positioning rod is driven to move. When the positioning hole 671 is opposite to the second positioning pin 665, the second positioning pin is inserted into the positioning hole to position the positioning rod, so that the locking assembly continuously positions the carrier plate 52. Until the second piston is released, the air pressure in the second piston cavity is reduced, and the second positioning pin releases the positioning rod. The carrier plate 52 can be pulled out.
