Description

[0002] In daily life, contact lenses are common vision correction products different from conventional glasses. They have brought great improvements to patients with refractive errors such as myopia, hyperopia, and astigmatism in terms of appearance and convenience. Moreover, they have a wide field of vision and vivid vision, and are also used to beautify the external appearance of the eyeball. After the initial production of contact lenses is completed, it is necessary to conduct optical detection on the contact lens. In existing automatic vision detection equipment for optical lenses / contact lenses, the detection ability / detection success rate of many automatic vision detection devices is also challenged. Because there are many uncertain factors in the production process, the detection quality decreases. For example, dust generated by environmental dust or friction, bubbles generated during liquid injection that are not discharged in time, defects in the detection container, or hidden injuries in the optical lens / contact lens and many other unpredictable factors affect the imaging focal length of the optical lens to be detected, resulting in poor imaging quality of the detected image, low clarity of the detection image, which will affect the defect detection rate of visual detection, the overall detection efficiency, and will also cause defective products that are missed in the inspection to flow into the market, causing additional losses. Therefore, there is a need for an optical lens detection mechanism that can improve the clarity of the optical lens imaging, eliminate some misjudgment factors affecting visual detection, and then effectively improve the detection efficiency and detection quality, and effectively avoid the occurrence of defective products being missed in the inspection for use in the detection of defective products in finished contact lenses.

Specific embodiments

[0042] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0043] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated with it, or there may be an intermediate element present at the same time. The terms "mounted", "one end", "the other end" and similar expressions used in this article are for illustrative purposes only.

[0044] Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as those commonly understood by those skilled in the art to which this technology belongs. The terms used in the description of this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more of the related listed items.

[0045] Reference Figure 1-5 , the present invention provides an optical lens detection mechanism, including a detection loading platform 1-1, a detection component 1-2, and a detection container component 1-3, and also includes a control unit (not shown). The detection container component 1-3 is arranged on the detection loading platform 1-1. The detection loading platform 1-1 is a transparent and light-transmitting detection loading platform. The detection component 1-2 is arranged on the detection container component. A detection light source is arranged at the bottom of the detection container component 1-3, and the detection light source is electrically connected to the control unit. The detection component 1-2 includes a projection member and a detection member 1-21. The detection light source 1-22 and the detection member 1-21 form a detection optical axis 1-4 on the central axis of the detection container component. The optical reflection of the projection member covers the detection container component, and the central axis of the projection member coincides with the axis formed by the detection optical axis 1-4. The detection container component 1-3 includes a detection container body 1-31. A liquid diversion position is provided on the detection container body 1-31, and the liquid diversion position is used to control the liquid injection height in the detection container body. The liquid injection height is a factor affecting focusing.

[0046] Reference Figure 1-4. In a preferred embodiment, the detection member 1-21 is provided with a detection lens group 1-211, and an industrial camera can also be provided. The projection member is a projection plate 1-23. The detection lens group is arranged below the projection plate 1-23. The detection assembly 1-2 further includes a liquid injection member 1-24. The liquid injection member 1-24 is used to inject a light-transmitting liquid Y onto the detection container assembly. When specifically implementing the embodiment, the liquid injection member 1-24 further includes a liquid injection unit 16 and a liquid injection pipe. The control unit is electrically connected to the liquid injection unit 16 to control the liquid injection unit 16 to inject the light-transmitting liquid Y into the detection container body through the liquid injection pipe. The liquid injection unit 16 controls the flow rate of the liquid injection. The liquid injection unit 16 is additionally arranged on the moving carrier of the detection mechanism. After the light-transmitting liquid Y is injected into the detection container body 1-31, a first liquid injection height is formed. The formed first liquid injection height provides a basic condition for the subsequent imaging step. Controlling the first liquid injection height formed by the liquid injection unit can achieve the purpose of focusing. If there are other fine impurities on the optical lens, such as dust or debris, and the steam bubbles generated during the liquid injection process will adhere to the optical lens. The control unit controls the irradiation light emitted by the detection light source to project through the detection container body. Then, all the features of the optical lens to be detected will be projected onto the projection plate, and thus an optical lens image T1 to be detected is formed, but the clarity is not high. If the first liquid injection height is higher, the bubbles generated by the liquid injection will escape, and the dust or debris will decrease with the change of the first liquid injection height, improving the clarity of the imaging of the optical lens image T1 during visual detection. The liquid injection unit achieves focusing by controlling the first liquid injection height. If there are dust, debris or bubbles generated by the liquid injection on the surface of the optical lens, these impurities will adhere to the lens surface, affecting the imaging clarity.

[0047] Reference Figure 1 -4. In a preferred embodiment, a detection position is provided in the middle of the detection loading platform 1-1. The detection container body is arranged at the detection position of the detection loading platform 1-1. The detection position is the central position in the middle of the detection loading platform. The optical lens to be detected is first placed in the detection container body 1-31. The surface of the loading platform is a transparent plate. A liquid guide groove 1-5 is arranged at the detection position. The liquid guide groove 1-5 is used to filter and recover the overflowing light-transmitting liquid Y. The liquid guide groove 1-5 recovers the excess light-transmitting liquid Y. Specifically, the light-transmitting liquid Y can be water, deionized water, physiological saline or maintenance liquid and other related preservation liquids.

[0048] Reference Figure 1-4. In a preferred embodiment, a liquid diversion opening 1-32 is provided on the detection container body 1-31. The liquid diversion openings 1-32 are symmetrically arranged on both sides of the detection container body. The cross-section of the liquid diversion opening 1-32 is an angled liquid diversion opening, which is used to control the liquid injection height in the detection container body, overflow and divert the excess light-transmitting liquid Y, and overflow out of the detection container body. The liquid diversion opening is set in an angled shape. During the overflow diversion of the incoming liquid, the diversion surface formed by the angled shape is beneficial to the smooth outflow of the light-transmitting liquid Y from the detection container cup body, reducing the fluctuation on the surface of the light-transmitting liquid Y in the detection container body, and thus effectively controlling the image focal length of the optical lens image T1 to be detected. Specifically, a limiting groove 1-33 can also be provided at the bottom of the detection container body. The height of the limiting groove 1-33 is greater than or equal to the overall height of the optical lens to be detected, so that the optical lens to be detected can be accommodated in the limiting groove 1-33. There should be a gap between the arc surface angles of the two edges of the limiting groove and the edge parts on both sides of the optical lens. The unit of the gap distance is millimeters and can be within the range of 1-2 millimeters. Since the optical lens itself has two arc surfaces and is a detection object with a relatively special shape, the set limiting groove is also to further comprehensively detect the optical lens in place and ensure that the defects on the edge arc surface part can be detected. The included angle between the edge parts on both sides of the optical lens (that is, the edge parts formed by the two curved surfaces) and the horizontal line is θ1; in the other side after inversion, the included angle between the edge part 1-45 and the horizontal line is θ2; due to the elastic material of the optical lens itself, θ1 is greater than θ2. When the detection light source passes through the limiting groove 1-33 at the same time, the settings of these three main bodies, namely the limiting groove 1-33, the light-transmitting liquid on the detection container body, and the optical lens to be detected, will affect the imaging quality of the optical lens image T1 to be detected. When the detection light source passes through the detection container body 1-31, there will be a refraction phenomenon, which will affect the imaging quality of the optical lens on the projection plate 1-23. If the focusing is good, the optical lens image T1 will be clearly imaged, and all the influences in the limiting groove can be clearly projected on the projection plate. The industrial camera transmits the detected optical lens image T1 to the next detection mechanism for detection, which is beneficial to the detection of defective products in the detection lens group. If the focusing is not good or out of focus, there will be a situation of missed detection of defective products, affecting the quality detection and reducing the detection efficiency;

[0049] In a specific embodiment, the height of the limiting groove is set as A1. When injecting the light-transmitting liquid Y, if the first liquid injection height is greater than A1, that is, when the first liquid injection height is H1, the bubbles generated by the liquid injection will escape, and dust or debris will suspend in the upper liquid. The dust or debris attached to the optical lens will decrease with the change of the first liquid injection height, which is beneficial to focusing, improving the clarity of the optical lens image T1 during visual detection, improving the imaging quality, and enhancing the detection effect of the optical lens detection.

[0050] Reference Figure 5-14 Moreover, a preferred embodiment of the present invention further provides a moving carrier for a detection mechanism, including a connecting carrier seat 1, a transmission mechanism 2 and a detection mechanism 3 arranged on the connecting carrier seat.

The transmission mechanism 2 includes a first detection tray transmission module 21, a second detection tray transmission module 22 and a clamping component 4. The clamping component 4 is arranged above the first detection tray transmission module 21 and the second detection tray transmission module 22 through a slide driving component 5. Both the first detection tray transmission module 21 and the second detection tray transmission module 22 are transmitted in a first direction. The slide driving component 5 is used to drive the clamping component 4 to reciprocate above the detection mechanism 3. The detection mechanism 3 includes a detection table seat component 31, a moving detection component 32 and an optical lens detection mechanism. The moving detection component 32 is arranged above the detection table seat component 31 through a driving connection component 6. The optical lens detection mechanism is arranged on the detection table seat component. The driving connection component 6 is used to drive the moving detection component to move above the detection table seat component. The optical lens detection mechanism is used to perform quality detection on the detection table seat component. The optical lens detection mechanism is the optical detection mechanism provided in the above preferred embodiment.

[0051] Reference Figure 5-14, in a preferred embodiment, a first mounting position 11 and a second mounting position 12 are provided on the connecting carrier base 1. Specifically, the first mounting position 11 and the second mounting position 12 are the left and right positions on the connecting carrier base. The transmission mechanism 2 is connected to the first mounting position 11, that is, the transmission of the contact lens material to be detected is arranged on one side of the connecting carrier base. The detection mechanism 3 is connected to the second mounting position 12, and the measuring die element for detection is arranged on the other side, which is convenient for detection. The first detection tray transmission module 21 and the second detection tray transmission module 22 are arranged at intervals on the first mounting position. The slide table driving assembly 5 includes a gantry connecting frame 51, a driving power member and a guiding connecting tank chain. The driving power member and the guiding connecting tank chain are both connected to the gantry connecting frame 51. The arranged gantry connecting frame 51 is used to connect the driving power member and the guiding connecting tank chain. The installation space of the gantry is relatively wide, which can appropriately extend the moving range of the clamping assembly, broaden the moving range of the clamping assembly, improve the transfer efficiency of the tray, quickly move it to the optical lens detection mechanism for quality detection, and also ensure the stability of the overall installation structure. The gantry connecting frame 51 includes a middle connecting support 52 and side connecting seats 53. There are two side connecting seats 53, which are respectively arranged on both sides of the connecting carrier base 1. The two ends of the middle connecting support 52 are respectively connected to the two side connecting seats through slider seats 7. The guiding connecting tank chain is provided with a first guiding tank chain 54 and a second guiding tank chain 55. The two arranged guiding tank chains are used for guiding in two directions. The first guiding tank chain 54 is used to guide the movement of the clamping assembly, and the second guiding tank chain 55 is used to guide the movement of the middle connecting support 52. The moving structure is stable. The clamping assembly 4 is slidably connected to one side of the middle connecting support 52 through a transverse slider seat 41. On the other side of the middle connecting support 52, a first guiding tank chain 54 is connected in parallel with the transverse slider seat 41. Reinforcing rib blocks 56 are connected at intervals on the other side of the middle connecting support 52. A tank chain recovery groove 57 is connected through a connecting piece. One end of the first guiding tank chain 54 is connected to the upper part of the clamping assembly through a connecting seat 541, and the other end is connected to one end of the tank chain recovery groove. When the first guiding tank chain 54 is guiding, it will extend or retract and move in the tank chain recovery groove 57. The structure is compactly arranged to ensure the stability of the clamping assembly 4 during operation. The clamping principle of the clamping assembly 4 is the clamping principle of negative pressure adsorption. When negative pressure adsorption is carried out, it can ensure the rapid movement of the spectacle lens blank. At the same time, because the spectacle lens blank is relatively thin and brittle, it should be avoided being touched and worn during the movement. Therefore, the arranged negative pressure clamping assembly can automatically move the spectacle lens blank to the position of the detection mechanism for rapid detection of the spectacle lens blank;The driving power member includes a first direction driving member and a second direction driving member. The first direction driving member includes a side motor module 58 and a direct motor member 59. The side motor module 58 is arranged at one end of the middle connecting support. The output end of the side motor module 58 is connected to one end of the middle ball screw through a synchronous belt and a synchronous wheel.
