Description

Technical Field

[0001] The present invention belongs to the technical field of lens detection, and in particular to a lens detection machine for optically detecting lens defects, and an automatic lens wiping device and a program thereof for wiping the lens before detecting the lens in the lens detection machine. Background Art

[0002] With the development of technology, optical lenses have been widely used in smart phones, video surveillance and other fields.

[0003] The optical lens is the most important part of a precision instrument. During the manufacturing, transportation and storage process, it may have defects such as blemishes, dirt, scratches, cracks, breakage, dust, fingerprints, watermarks, etc. due to internal and / or external factors.

[0004] Optical lenses are easily attached with dust during transportation and storage. In order to remove the dust attached to the optical lenses, they must be dusted before testing.

[0005] At present, the most common dust removal method is the air blowing method, that is, a manually operated jet tool that can spray out dust removal gas at a certain flow rate, and the dust removal effect is achieved by spraying dust removal gas with a certain flow rate to the lens through the jet tool. Not only is the operation efficiency relatively low, but if there are other surface substances attached to the lens (such as water-containing stains), the air blowing method is likely to fail to achieve the effect of removing the other attached surface substances. If the flow rate of the dust removal gas is increased, it is very likely to cause damage to the lens, and it also means that more power consumption is required for dust removal. Summary of the invention

[0006] The purpose of the present invention is to provide a lens inspection machine and an automatic lens wiping device and a program thereof, which can not only clear the dust attached to the lens surface, but also have a greater chance of removing other difficult-to-remove attached substances on the lens surface.

[0007] Based on the above purpose, the present invention proposes an automatic lens wiping device for preserving stored objects at low temperatures, the automatic lens wiping device comprising: The lens carrier comprises a lens carrier plane for carrying a plurality of the lenses, wherein the setting direction of the lens carrier plane is substantially parallel to the moving direction of the lenses matched therewith; when in operation, all the lenses located on the lens carrier plane are arranged along the moving direction of the lenses; A reciprocating lens pushing assembly is used to push all the lenses matched with it and simultaneously move forward on the lens bearing surface along the moving direction of the lens for a preset pushing member moving distance before resetting; A wiping assembly is arranged transversely in the moving direction of the lens, and comprises a wiping support and a wiping head arranged thereon. When working, the wiping surface of any one of the lenses pushed by the reciprocating lens pushing assembly rubs against the wiping head passing through the wiping assembly during the process of passing through the wiping assembly, and the wiping head does not move during the rubbing process; The material selected for the wiping head is a flexible solid material, and the hardness of the flexible solid material must be less than or equal to a preset scratch depth threshold of the scratches formed on the lens during friction; Wherein, the wiping head is detachably arranged on the wiping support member.

[0008] In one example, when the wiping surface on the lens to be wiped by the wiping device is a non-horizontal surface: The number of the lens carriers is at least two, all the lens carriers are arranged in sequence along the moving direction of the lens, and a preset lens carrier angle is formed between any two adjacent lens carriers; The number of the reciprocating lens pushing components is several, and each lens carrier corresponds to at least one reciprocating lens pushing component; The number of the wiping components is several, and each lens carrier corresponds to at least one wiping component.

[0009] In one example, at least one of the lens carriers corresponds to at least two of the wiping components, and all of the wiping components corresponding to the lens carrier are arranged along the setting direction of the lens carrying plane on the lens carrier.

[0010] In one example, when the number of wiping surfaces on the lens is two, and one of them is located on the top side of the lens and the other is located on the bottom side of the lens: The number of the wiping components is at least two, at least one of which is located above the top side of the lens matched therewith, and at least another one of which is located below the bottom side of the lens matched therewith; The lens carrier also includes at least one wiping opening opened on the lens carrying plane and arranged along the moving direction of the lens. The wiping opening cooperates with the wiping assembly below so that a wiping head in the wiping assembly below extends out of the wiping opening to cooperate with the wiping surface on the bottom side of the lens.

[0011] In one example, the number of the wiping components located above and the wiping components located below are the same and correspond one to one, and any corresponding wiping component located above and any corresponding wiping component located below are respectively used to simultaneously cooperate with the wiping surface on the top side of the lens and the wiping surface on the bottom side of the lens passing therethrough.

[0012] In one example, a wiping force adjustment component is also included, which cooperates with the wiping component and includes: The wiping force regulating driver cooperates with the wiping head to adjust the pressure between the wiping head and a wiping surface on the lens cooperated therewith, thereby adjusting the friction force value of the wiping head acting on the wiping surface of the lens.

[0013] In one example, the size and shape of the portion of the wiping head that matches the wiping surface on the lens in an unpressed state are adapted to the size and shape of the portion of the wiping surface on the lens that matches the wiping head.

[0014] In one example, the reciprocating lens pushing assembly includes: A reciprocating lens push drive; and A reciprocating lens pushing member cooperates with the reciprocating lens pushing driver. Under the action of the reciprocating lens pushing driver, the reciprocating lens pushing member reciprocates substantially along a setting direction parallel to the lens bearing plane on the lens bearing member corresponding to the reciprocating lens pushing member; Wherein, the reciprocating lens pushing member is provided with a lens isolating portion for isolating all the pushed lenses from each other.

[0015] Based on the above purpose, the present invention provides a computer program product, including computer instructions, wherein the computer instructions are used to enable a computer to execute a lens wiping method for wiping a lens; The lens wiping method is applied to a lens placed in an automatic lens wiping device, and the automatic lens wiping device comprises: The lens carrier comprises a lens carrier plane for carrying a plurality of the lenses, wherein the setting direction of the lens carrier plane is substantially parallel to the moving direction of the lenses matched therewith; when in operation, all the lenses located on the lens carrier plane are arranged along the moving direction of the lenses; A reciprocating lens pushing assembly is used to push all the lenses matched with it and simultaneously move forward along the moving direction of the lens on the lens bearing surface for a preset pushing member moving distance and then reset, comprising a reciprocating lens pushing driver and a reciprocating lens pushing member matched with it. When working, under the action of the reciprocating lens pushing driver, the reciprocating lens pushing member basically reciprocates along the setting direction parallel to the lens bearing plane on the lens bearing member corresponding to it; A wiping assembly is disposed transversely in the moving direction of the lens, and comprises a wiping support and a wiping head disposed thereon. When in operation, the wiping surface of any one of the lenses pushed by the reciprocating lens pushing assembly rubs against the wiping head passing through the wiping assembly during the process of passing through the wiping assembly, and the wiping head does not move during the rubbing process; and A wiping force adjustment component cooperates with the wiping component, including a wiping force adjustment driver cooperates with the wiping head to adjust the pressure between the wiping head and a wiping surface on the lens cooperated therewith, thereby adjusting the magnitude of the friction force of the wiping head acting on the wiping surface of the lens; Wherein, the reciprocating lens pushing member is provided with a lens isolating portion for isolating all the pushed lenses from each other; The material selected for the wiping head is a flexible solid material, and the hardness of the flexible solid material must be less than or equal to a preset scratch depth threshold of the scratches formed on the lens during friction; Wherein, the wiping head is detachably arranged on the wiping support; The lens wiping method comprises the following steps: Sending a wiping head approach instruction to the wiping force adjustment driver, instructing it to push the wiping head away from the preset wiping head initial position and then to the preset wiping head approach position; Sending a lens pushing instruction to the reciprocating lens pushing driver, instructing it to push the reciprocating lens pushing member to move forward from a preset pushing member initial position substantially along a moving direction parallel to the lens by a preset pushing member moving distance, and at the same time, the lens moves forward by a preset pushing member moving distance under the push of the reciprocating lens pushing member, and in the process of moving forward by a preset pushing member moving distance along the moving direction parallel to the lens, the wiping head at the preset wiping head approaching position rubs against a wiping surface of the lens passing by it; Sending a wiping head away instruction to the wiping force adjustment driver, instructing it to pull the wiping head back to a preset wiping head initial position; Sending a push component reset instruction to the reciprocating lens push driver, instructing it to push the reciprocating lens push member to move backward substantially in a direction parallel to the movement of the lens by a preset push member moving distance to return to the preset push member initial position; Repeat any or more of the above steps.

[0016] Based on the above purpose, the present invention also provides a lens inspection machine, comprising a lens moving device to be wiped, a lens automatic wiping device and a wiped lens inspection device which are sequentially arranged along the moving direction of the lens during operation; The device for moving the lens to be wiped into the device comprises: The shift arm is used to move the lens to be wiped in; A pick-and-place assembly for moving the lens to be wiped in is arranged at the output end of the shift arm for moving the lens to be wiped in; The automatic lens wiping device comprises: The lens carrier comprises a lens carrier plane for carrying a plurality of the lenses, wherein the setting direction of the lens carrier plane is substantially parallel to the moving direction of the lenses matched therewith; when in operation, all the lenses located on the lens carrier plane are arranged along the moving direction of the lenses; A reciprocating lens pushing assembly is used to push all the lenses matched with it and simultaneously move forward along the moving direction of the lens on the lens bearing surface for a preset pushing member moving distance and then reset, comprising a reciprocating lens pushing driver and a reciprocating lens pushing member matched with it.

[0028] The present invention will be described below with reference to several examples. It should be understood that these embodiments are described to enable those skilled in the art to better understand and implement the present invention, and do not represent or imply any limitation on the scope of the present invention.

[0029] Lens, in the field to which the present invention belongs, mainly refers to an optical component.

[0030] When used as an optical component, this lens can be used not only as a lens for glasses in the traditional field, but is also an indispensable component in cameras, smartphones, computers, image sensors, etc.

[0031] There are many types of lenses. When choosing, you need to choose a lens with different parameter values ​​according to actual needs.

[0032] Common lens parameters, such as focal length, aperture, equivalence, etc., have an important impact on the performance and use of the lens. ‌ Before leaving the factory, there is a need for a quality inspection process for the manufactured lenses.

[0033] Before testing the lens, it is necessary to remove substances that may be attached to the surface of the lens (such as dust particles, water-containing stains, etc.) in advance, otherwise it is very likely to affect the quality inspection results of the lens.

[0034] At present, most manufacturers still use the method of manually wiping the surface of the lens, which is not only inefficient, but also prone to secondary contamination due to manual contact. In addition, some manufacturers use jet-jet tools to treat the surface of the lens by blowing. This blowing method may not be as effective as when the surface of the lens is a stain containing liquids such as water as when the surface is just dust particles. In addition, if the blowing method cannot control the direction of the airflow, it will cause backflow, causing the surface of the lens to return to the lens or other lenses after being blown away from the lens, resulting in a low efficiency in removing the surface.

[0035] In order to achieve the purpose of solving at least one of the above problems, the relevant technical solutions in the present invention are provided, which are specifically described as follows.

[0036] An embodiment of the lens inspection machine of the present invention comprises a device for moving in a lens to be wiped, a device for automatically wiping a lens, and a device for inspecting a wiped lens.

[0037] The lens moving device to be wiped is responsible for automatically conveying the lens to the automatic lens wiping device; the automatic lens wiping device is responsible for automatically wiping the input lens; the wiped lens detection device is responsible for automatically detecting the wiped lens. The specific structures of the above devices are as follows.

[0038] The lens to be wiped moves into the device As an example of the device for moving the lens to be wiped, Figure 1 , 2As shown in FIG. 3 , the lens moving device 100 includes a shift arm 110 for moving the lens to be wiped and a gripping and placing assembly for moving the lens to be wiped. The gripping and placing assembly for moving the lens to be wiped is arranged at the output end of the shift arm 110 for moving the lens to be wiped.

[0039] During operation, the shift arm 110 for moving the lens to be wiped drives the grasping and placing assembly for moving the lens to be wiped to a specified position (such as a position where the lens needs to be extracted, or a position where the lens needs to be placed), and then the grasping and placing assembly for moving the lens to be wiped grasps or releases the lens a.

[0040] The shift arm 110 for moving the lens to be wiped in is a mechanical arm device, and a corresponding structure having the function of operating in one dimension, two dimensions or three dimensions can be provided as required.

[0041] An example of a shift arm of any dimension in the shift arm for moving the lens to be wiped in may include a one-dimensional shift driver and a linear moving-in conveying structure. When working, under the drive of the one-dimensional shift driver, the shift arm of another dimension connected to the output end of the linear moving-in conveying structure is connected to move forward or backward along the one-dimensional direction.

[0042] An example of the linear transport structure is as follows: Figure 1 , 2 3, including a linear moving-in drag chain (not shown in the figure), a linear moving-in guide rail 102, and a linear moving-in slider 103 slidably disposed on the linear moving-in guide rail 102, and the displacement arm in the other dimensional direction can be directly or indirectly disposed on the linear moving-in slider 103. In another example, it can also be composed of a linear moving-in conveyor belt (not shown in the figure), a linear moving-in conveyor pulley (not shown in the figure), and a linear moving-in fastening component (not shown in the figure) fastened to the linear moving-in conveyor belt, and the displacement arm in the other dimensional direction can be directly or indirectly disposed on the linear moving-in fastening component.

[0043] An example of a pick-and-place assembly for moving the lens to be wiped is as follows: Figure 1 , 2 , 3, including a pick-and-place vacuum suction device 121 for moving in and a vacuum generator for picking up and releasing (not shown in the figure). It uses the vacuum adsorption principle to realize the operation of picking up and releasing the lens a through the pick-and-place vacuum suction device 121 for moving in. In order to improve the grabbing efficiency, in another example, the number of the pick-and-place vacuum suction devices 121 for moving in is several and arranged in a row or a column, and the intervals between the pick-and-place vacuum suction devices 121 for moving in are adapted to the intervals of the lenses to be grabbed, so that the purpose of grabbing or releasing multiple lenses at one time can be achieved.

[0044] Automatic lens cleaning device As an example of the automatic lens wiping device, Figure 5 , 6 As shown in Figures 7 and 8, the automatic lens wiping device 200 includes a lens carrier, one or more reciprocating lens pushing components, and one or more wiping components.

[0045] During operation, one of the lens carriers carries the lens moved in from the lens moving device to be wiped, and the reciprocating lens pushing assembly is disposed adjacent to two sides of the lens carrier that are substantially parallel to the moving direction of the lens thereon. The reciprocating lens pushing assembly pushes the lens on the lens carrier to move on the lens carrier along the moving direction of the lens. During the movement of the lens, one or more wiping surfaces on the lens generate friction with the wiping assembly in a relatively static state, so as to achieve the purpose of automatically wiping the lens.

[0046] That is, the movement of the moving lens and the friction of the wiping component in a relatively static state are used to complete the purpose of wiping the lens. This structural setting not only achieves the purpose of automatic wiping, but more importantly simplifies the wiping operation steps of the wiping component and the corresponding operating structure in the wiping component.

[0047] As an example of the lens carrier, Figure 2 , 3 As shown in , 4, 5, 6, 7, and 8, it includes a lens supporting platform 201, on which is provided a lens supporting plane 202 for the lens a to move, and the length direction of the lens supporting plane 202 is set in a direction that is substantially parallel to the moving direction of the lens a moving thereon.

[0048] The lens carrying plane 202 has a plurality of lenses arranged in sequence in the length direction thereof. The lens carrying plane 202 may have one lens arranged in the width direction (ie, the transverse direction) thereof, or may have a plurality of lenses arranged side by side.

[0049] The reciprocating lens pushing assembly is used to push all the lenses matched with it and simultaneously move forward along the moving direction of the lens on the lens bearing surface for a preset pushing member moving distance and then reset. The reciprocating lens pushing assembly includes a reciprocating lens pushing driver and a reciprocating lens pushing member matched with it. Under the action of the reciprocating lens pushing driver, the reciprocating lens pushing member basically reciprocates along a setting direction parallel to the lens bearing plane on the lens bearing platform corresponding to it.

[0050] An example of the preset moving distance of the pusher is slightly greater than the maximum length of the lens along its moving direction, so that in one pushing process, all the lenses on the lens bearing plane 202 complete a movement of a distance slightly greater than the maximum length of the lens along its moving direction. This is conducive to completing a complete wiping process of the lens in one movement. Of course, the preset moving distance of the pusher can also be set to other values ​​as needed.

[0051] An example of the reciprocating lens pushing driver includes a reciprocating lens pushing motor (not shown) and a linear pushing conveying structure.

[0052] An example of the linear push conveying structure is as follows: Figure 2 , 3 , 4, 5, 6, 7, and 8, including a linear push drag chain (not shown in the figure), a linear push guide rail 203, and a linear push slider 204 slidably arranged on the linear push guide rail 203, and the reciprocating lens pusher is directly or indirectly arranged on the linear push slider 204. In another example, the linear push conveying structure includes a linear push screw of a screw structure, and a nut disposed on the linear push screw that can move along the axis direction of the linear push screw is directly or indirectly connected to the reciprocating lens pusher. In another example, the linear push conveying structure includes a linear push conveyor belt (not shown in the figure), a linear push conveyor pulley (not shown in the figure), and a linear push fastening component (not shown in the figure) fastened to the linear push conveyor belt, and the reciprocating lens pusher is directly or indirectly arranged on the linear push fastening component.

[0053] In one example of the reciprocating lens pusher, Figure 2 , 3 , 4, 5, 6, 7, and 8, it is composed of a pair of separate reciprocating lens pushing rods 205, which are respectively arranged on both sides of the lens support platform 201 along the moving direction of the lens a. When working, the reciprocating lens pushing member cooperates with the lateral sides of the lens a. In another example, as Figure 2 , 3 As shown in Figures 4, 5, 6, 7 and 8, a lens isolation portion 206 is also provided on the reciprocating lens pushing rod 205 for isolating all the lenses a pushed, thereby reducing the probability of two adjacent lenses colliding with each other during the process of pushing the lenses a and providing a certain protective effect on the lenses a.

[0054] In addition, a plurality of the reciprocating lens pushing assemblies may be correspondingly arranged on one lens carrier, and in this case, the reciprocating lens pushing members in all the reciprocating lens pushing assemblies are arranged in sequence along the moving direction of the lens on the lens carrier. Of course, only one reciprocating lens pushing assembly may also be arranged, and in this case, the sum of the length of one of the reciprocating lens pushing members in one of the reciprocating lens pushing assemblies plus the preset moving distance of the pushing member is substantially equal to the length of the lens bearing plane on the lens carrier along the moving direction of the lens.

[0055] The wiping assembly comprises a wiping support and a wiping head arranged thereon.

[0056] As an example of the wiping component, Figure 2 , 3 As shown in , 4, 5, 6, 7, and 8, the wiping assembly is statically arranged horizontally above and / or below the lens a moving on the lens carrier 201, and includes a wiping support frame 207 as an example of the wiping support member and a wiping head 208 arranged thereon. When working, the wiping surface on any one of the lenses pushed by the reciprocating lens pushing assembly rubs against the wiping head passing through the wiping assembly during the process of passing through the wiping assembly, and the wiping head does not move during the rubbing process. Of course, the wiping assembly can also be arranged at other positions, as long as the wiping assembly matches the wiping surface on the lens passing through it.

[0057] When the wiping assembly is horizontally arranged below the lens moving on the lens supporting platform 201, at least one wiping opening (not shown in the figure) needs to be opened on the lens supporting plane 202 on the lens supporting platform 201, and the wiping opening cooperates with the wiping assembly below so that the wiping head in the wiping assembly below can extend out of the wiping opening and cooperate with the wiping surface on the bottom side of the lens.

[0058] When a plurality of wiping openings are provided on each lens bearing plane 202 , all the wiping openings are arranged on the lens bearing plane along the moving direction of the lens.

[0059] The material selected for the wiping head is a flexible solid material, that is, a flexible material that will deform under external force. At the same time, it is also a solid material rather than a liquid material or a gaseous material.

[0060] First, the hardness (eg, Mohs hardness) of the flexible solid material must be lower than the hardness (eg, Mohs hardness) of the lens to be wiped.

[0061] Then, the hardness (such as Mohs hardness) of the flexible solid material is also required to be: when working, the flexible solid material used as the wiping head needs to be able to achieve the purpose of "wiping the wiping surface of the lens passing through it to remove the substances (such as dust, etc.) attached to the wiping surface of the lens", and at the same time meet the purpose of "reducing the probability of scratches on the wiping surface during the wiping process, or even if there are scratches, the depth of the scratches meets the tolerable standard of lens damage" (that is, the hardness of the flexible solid material must be less than or equal to the preset scratch depth threshold of the scratches formed on the lens during wiping). Only in this way, the wiping head in the present invention can achieve the purpose of wiping off the substances attached to the lens and reducing the probability of damage to the lens during the wiping process; otherwise, even if the purpose of wiping off the substances attached to the lens is achieved, if more damage to the lens is formed during the wiping process (that is, the scratches formed on the lens are greater than the preset scratch depth threshold), the lens will be finally detected as unqualified and scrapped.

[0062] In view of the above-mentioned hardness (such as Mohs hardness) requirement, the hardness (such as Mohs hardness) of the flexible solid material must firstly be less than the hardness (such as Mohs hardness) of the material of the lens, and moreover, must satisfy the condition of "reducing the probability of scratches on the wiping surface during the wiping process or, even if scratches occur, the depth of the scratches meets the tolerable standard of lens damage". For this reason, in the present invention, the flexible solid material can be selected from the materials used for textiles.

[0063] The textiles mainly include knitted fabrics, woven fabrics and non-woven fabrics. The materials of the yarns used in the knitted fabrics and woven fabrics (such as silk, real silk, linen, cotton, polyester, nylon and other fibers that make up the fabrics) can be used as the flexible solid material in the present invention. Non-woven fabrics (such as masks) can also be used as the flexible solid material in the present invention.

[0064] Since the wiping head will inevitably be covered with a lot of substances (such as dust, etc.) from the wiping surface of the lens after working for a period of time, the wiping head must be replaced after a certain amount of substances accumulate. Therefore, the wiping head is detachably arranged on the wiping support. For example, the wiping head is tied to the wiping support by a rope, or is clamped to the wiping support by a clamping structure, or is inserted into the wiping support by a plug-in structure.

[0065] Any lens support platform 201 may be provided with one wiping assembly, or may be provided with a plurality of wiping assemblies in sequence along the moving direction of the lens on the lens support platform 201 .

[0066] In addition, when a plurality of lenses are arranged side by side in the width direction (i.e., the lateral direction) of the lens bearing plane 2022 on the lens bearing platform 201, a corresponding number of wiping components may also be arranged in the width direction (i.e., the lateral direction) of the lens bearing plane 2022, or only one wiping component may be arranged. However, the length of the wiping head on the wiping component extending along the width direction (i.e., the lateral direction) of the lens bearing plane 2022 must at least meet the requirement of being able to simultaneously wipe a row of lenses arranged side by side in the lateral direction.

[0067] In one example of the wiping head, the size and shape of the portion of the wiping head that matches the wiping surface on the lens in an unpressed state are adapted to the size and shape of the portion of the wiping surface on the lens that matches the wiping head. In this way, during the wiping process, especially when the size and shape of the wiping head and the wiping surface are exactly the same, the entire wiping surface can be wiped, increasing the possibility that the lens reaches the preset wiping standard after being wiped.

[0068] The number of wiping surfaces on the lens that need to be wiped may be one or two.

[0069] When there are two wiping surfaces to be wiped on the lens, as an example of the lens, Figure 2 , 3 , 4, 5, 6, 7, and 8, one of which is located at the top side of the lens and the other is located at the bottom side of the lens. In order to enable the lens to enter and exit the automatic lens wiping device once and complete wiping the two wiping surfaces on the lens, two wiping components are required to be provided to respectively cooperate with the two wiping surfaces on the lens, that is, the wiping head on the upper wiping component cooperates with the wiping surface on the top side of the lens, and the wiping head on the lower wiping component cooperates with the wiping surface on the bottom side of the lens.

[0070] In addition, the wiping head on the upper wiping assembly and the wiping head on the lower wiping assembly of the two wiping assemblies may be located on the same straight line or may be staggered in the moving direction of the lens.

[0071] When the wiping surface is provided on both the top side and the bottom side of the lens, the number of the wiping components located on the top and the number of the wiping components located on the bottom may be the same or different.

[0072] The position of the wiping head on the wiping assembly is not adjustable relative to the lens support platform 201, and the thickness of the lens may have different values. Therefore, the pressure between the wiping head and the wiping surface on the lens can only be adjusted by adjusting the thickness of the wiping head.

[0073] In order to make the position of the wiping head adjustable relative to the lens supporting plane on the lens supporting platform, in another example of the wiping assembly, a wiping force adjusting driver is also included. The wiping force adjusting driver cooperates with the wiping head to adjust the pressure value between the wiping head and a wiping surface on the lens cooperating therewith, thereby adjusting the friction force value of the wiping head acting on the wiping surface of the lens.

[0074] In addition, the function of the wiping force adjustment driver is that the wiping force adjustment driver drives the position adjustment of the wiping head and the movement coordination of the reciprocating lens pushing assembly. The above coordination is specifically: during operation, in the process from when the reciprocating lens pushing member on the reciprocating lens pushing assembly is located at the preset pushing member initial position to when the reciprocating lens pushing member moves forward a preset pushing member moving distance, the wiping head driven by the wiping force adjustment driver is always located at the preset wiping head approaching position; and before the reciprocating lens pushing member on the reciprocating lens pushing assembly is ready to return, the wiping force adjustment driver drives the wiping head to withdraw from the preset wiping head approaching position to the preset wiping head initial position.

[0075] When the wiping head is located at the preset wiping head initial position, the wiping head will not contact the lens passing through it; and when the wiping head is located at the preset wiping head approach position, the wiping head contacts and rubs with the lens passing through it, thereby producing a wiping effect.

[0076] When the position of the wiping head cannot be adjusted relative to the lens bearing plane on the lens bearing platform, the position of the wiping head is always relatively fixed during operation. If the reciprocating lens pushing member on the reciprocating lens pushing assembly has a situation where the lens and the wiping head are pressed against each other after the previous push, and the pressing situation is maintained until the next push of the reciprocating lens pushing member on the reciprocating lens pushing assembly, this may increase the probability that the pressed lens will be locked with the wiping head during the next push, thereby affecting the normal operation of the automatic lens wiping device.

[0077] An example of the wiping force adjustment driver includes a wiping force adjustment motor (not shown) and a linear wiping conveying structure. The wiping support member is relatively fixedly arranged on the output end of the linear wiping conveying structure. When working, the wiping support member connected to the output end of the linear removal conveying structure is moved forward or backward along the straight line under the drive of the wiping force adjustment motor.

[0078] An example of the linear wiping conveying structure includes a linear wiping drag chain, a linear wiping guide rail, and a linear wiping slider slidably disposed on the linear wiping guide rail, and the wiping support member can be directly or indirectly disposed on the linear wiping slider. In another example, it can also be composed of a linear wiping transmission belt (not shown in the figure), a linear wiping transmission pulley (not shown in the figure), and a linear wiping fastening component (not shown in the figure) fastened to the linear wiping transmission belt, and the wiping support member can be directly or indirectly disposed on the linear removal fastening component. In yet another example, the linear wiping conveying structure includes a linear wiping screw of a screw structure, and a nut disposed on the linear wiping screw that can move along the axis direction of the linear wiping screw is directly or indirectly connected to the wiping support member.

[0079] When the wiping assembly in the automatic lens wiping device includes a wiping force adjustment driver, the lens wiping method that can be automatically implemented by the automatic lens wiping device (implemented by a computer program, i.e., a computer program composed of computer instructions) can be as described below.

[0080] Step 01, sending a wiping head approach instruction to the wiping force adjustment driver, instructing it to push the wiping head away from the preset wiping head initial position and then to the preset wiping head approach position.

[0081] It should be noted that the wiping head is away from the lens when it is in the preset wiping head initial position, and can ensure friction with the wiping surface on the lens passing by it when it is in the preset wiping head approach position. Before the wiping head works, it is in the preset wiping head initial position, not the preset wiping head approach position.

[0082] Step 02, sending a lens pushing instruction to the reciprocating lens pushing driver, instructing it to push the reciprocating lens pushing member to move forward a preset pushing member moving distance from a preset pushing member initial position basically along a moving direction parallel to the lens. At the same time, the lens moves forward a preset pushing member moving distance under the push of the reciprocating lens pushing member. In the process of moving forward a preset pushing member moving distance along the moving direction parallel to the lens, the wiping head in the preset wiping head approach position rubs against a wiping surface of the lens passing through it.

[0083] It should be noted that the method of using the reciprocating lens pushing member to push the lens makes it possible to basically achieve precise control of the distance the lens is pushed each time, and it is simple and easy to operate, that is, it is only necessary to control the reciprocating lens pushing member to move forward a preset pushing member moving distance each time, and then reset it, and repeat this cycle.

[0084] Step 03: Send a wiping head away instruction to the wiping force adjustment driver, instructing it to pull the wiping head back to a preset wiping head initial position.

[0085] It should be noted that after the lens is pushed to a new position, the wiping head which is at the preset wiping head approaching position during the pushing process retreats to the preset wiping head initial position away from the lens, so as to reduce the probability of the lens and the wiping head being in mutual pressure (i.e., applying pressure to each other) being locked in death during the next pushing, so as to facilitate the smooth pushing of the subsequent reciprocating lens pushing assembly.

[0086] Step 04, sending a push component reset instruction to the reciprocating lens push driver, instructing it to push the reciprocating lens push member to move backward a preset push member moving distance substantially parallel to the moving direction of the lens and return to the preset push member initial position.

[0087] It should be noted that the movement mode of the reciprocating lens pushing assembly is relatively simple, that is, there are only two actions, one is to move forward a preset pushing member moving distance from the preset pushing member initial position, and the other is a reset action, which makes the automatic control relatively simple.

[0088] In addition, when executing the above steps, any one of the above steps can be executed as a task, or several related steps among all the above steps can be executed as a task, and the task can be executed once or multiple times.

[0089] The above-mentioned computer program may be stored in a computer-readable storage medium, and the control unit may be used as hardware for executing the computer program.

Computer-executable instructions can be compiled or interpreted from a computer program, which is established using a variety of programming languages ​​and / or technologies, including but not limited to JavaTM, C, C++, Visual Basic, Java Script, Perl, etc., alone or in combination. Some of these applications can be compiled and executed on a virtual machine, such as a Java virtual machine, a Dalvik virtual machine, etc. Typically, a processor (e.g., a microprocessor) receives instructions, such as from a memory, a computer-readable medium, etc., and executes these instructions, thereby executing one or more processes, including one or more processes described herein. Such instructions and other data can be stored and transmitted using a variety of computer-readable media.

[0093] Computer-readable storage media (also referred to as processor-readable media) include any non-transitory (e.g., tangible) media that participate in providing data (e.g., instructions) readable by a computer (e.g., by a processor of a computer).

[0095] In some examples, the above-described operating methods may be implemented as computer-readable instructions (e.g., software) on one or more computing devices (e.g., servers, personal computers, etc.), stored on computer-readable media associated therewith (e.g., disks, memories, etc.). A computer program product may include such instructions stored on a computer-readable medium for performing the functions described herein.

[0096] The wiping surface on the lens may be flat or non-horizontal, such as a crown-shaped arc surface or an inclined plane. This makes it very likely that when the wiping head on the wiping component contacts the wiping surface of the lens passing through it, the forces acting on each point on the wiping surface will be different, which may cause the material attached to the partial area on the wiping surface where the force is relatively small to be unable to be wiped off or reach the preset wiping standard. Even if a plurality of the wiping components are arranged on the lens carrier, the distribution of the force magnitudes acting on each point on the wiping surface of the lens is basically the same when passing through the wiping heads on each of the wiping components. That is, when passing through the wiping heads on each of the wiping components, the partial area on the wiping surface of the lens where the force is relatively small is basically unchanged. Therefore, how to wipe the material attached to the part on the wiping surface where the force is relatively small to reach the preset wiping standard is a problem. In order to solve the above problem, another example of the automatic lens wiping device described below is produced.

[0097] Another example of the automatic lens wiping device includes two or more lens carriers, each of which is respectively matched with one or more reciprocating lens pushing components and one or more wiping components. All the lens carriers are arranged in sequence along the moving direction of the lens.

[0098] Any two adjacent lens carriers of all the lens carriers constituting the automatic lens wiping device form a preset lens carrier angle.

[0099] It should be noted that the size of the preset lens carrier angle can represent different values ​​at the same time, that is, the angle formed by two adjacent lens carriers and the angle formed by another two adjacent lens carriers can be the same or different.

[0100] The preset lens carrier angle may be in the range of greater than 0° and less than 180°.

[0101] Specifically, the preset lens carrier angle can be selected to be 90°, so that it is relatively easy to connect the lens carriers, that is, it is only necessary to keep one lens carrier perpendicular to the other adjacent lens carrier, and there is no need to use angle measuring tools to correct the angle.

[0102] In the case where the preset lens carrier angle is selected to be less than 90°, it may be beneficial to improve the utilization of space, making it possible to install in a relatively small space.

[0103] Another example of the working principle of the automatic lens wiping device is as follows: during the movement of a lens carrier, the wiping head on the wiping assembly corresponding to the lens carrier only wipes all the wiping surfaces of the lens passing through in one wiping direction. This results in that it may be difficult to reach the preset wiping standard for wiping the attached substances on the portion of the wiping surface that is subjected to relatively small forces in one wiping direction, and although the distribution of the magnitude of the forces exerted on the portions of the wiping surface on any lens during the movement on different lens carriers by the wiping head on the wiping assembly that wipes them is basically the same, the removal of the attached substances on the region on the wiping surface that is subjected to relatively small forces can be improved by wiping in multiple wiping directions, so as to increase the probability that the region on the wiping surface that is subjected to relatively small forces reaches the preset wiping standard. Another example of the automatic lens wiping device is to set the lens carrier at different angles so that the wiping surface of the lens is subjected to different wiping directions brought by wiping heads in different setting directions during the movement of different lens carriers.

[0104] Wiped lens detection device The wiped lens detection device is used for detecting the lens from the automatic lens wiping device.

[0105] As an example of the wiped lens detection device, Figure 1 , 2 As shown in FIGS. 3 and 4 , the wiped lens detection device 300 includes a lens support for detecting a wiped lens, a light source for detecting a wiped lens, and a camera for detecting a wiped lens.

[0106] The lens support for the wiped lens detection is used to support the lens to be detected. As an example of the lens support for the wiped lens detection, Figure 1 , 2 As shown in , 3 and 4, a lens supporting groove 301 for detecting a wiped lens is of a platform-type structure, and the lens a is placed on the lens supporting platform 301 for detecting a wiped lens during detection.

[0107] The wiped lens detection camera is used to capture the lens placed on the wiped lens detection lens support platform 301 to obtain image information of the lens. An example of the wiped lens detection camera is an industrial-grade camera to enhance the clarity of the image.

[0108] In addition, a light source for detecting the wiped lens is provided to provide an independent light source for the camera for detecting the wiped lens when the camera for detecting the wiped lens is working. An example of the light source for detecting the wiped lens is an LED light source. The setting position of the light source for detecting the wiped lens corresponds to the camera for detecting the wiped lens. When working, in order to make the light emitted by the light source for detecting the wiped lens irradiate the lens, the bottom of the lens support platform 301 for detecting the wiped lens is provided with a light source hole 302 for detecting the wiped lens for entering the light source for detecting the wiped lens. In order to improve the clarity of the image taken by the camera for detecting the wiped lens, the light source for detecting the wiped lens is directly facing the light source hole 302 for detecting the wiped lens, so that when the light source for detecting the wiped lens emits light, the light can pass through the light source hole 302 for detecting the wiped lens and enter the lens, and then enter the camera for detecting the wiped lens, so that the camera for detecting the wiped lens can take an image with higher clarity.

[0109] In order to facilitate the relative fixation of the position of the lens during detection, in one example, Figure 1 , 2 As shown in Figures 3, 4, a lens positioning groove 303 for wiped lens detection is also provided on the lens support platform 301 for wiped lens detection, so that the lens is positioned in the lens positioning groove 303 for wiped lens detection during detection. At this time, the light source hole 302 for wiped lens detection is provided at the bottom of the lens positioning groove 303 for wiped lens detection.

[0110] The lens support for detecting the wiped lens, the light source for detecting the wiped lens, and the camera for detecting the wiped lens are three parts that need to be matched. In one example, the number of the lens support for detecting the wiped lens, the light source for detecting the wiped lens, and the camera for detecting the wiped lens are multiple, so that multiple wiped lens detection points can be set in the wiped lens detection device, and each of the wiped lens detection points is provided with the lens support for detecting the wiped lens, the light source for detecting the wiped lens, and the camera for detecting the wiped lens. In this way, each of the wiped lens detection points can detect different targets, so that the integrity and accuracy of the detection of the entire wiped lens detection device may be better. That is, a lens passes the detection of multiple wiped lens detection points, and the detection results of one or more of the wiped lens detection points may be up to standard, but it is found that it is not up to standard in the detection of at least one of the wiped lens detection points, so as to improve the success rate of finding the defective lens through machine inspection (that is, the machine automatically detects whether there is a set defect in the lens). This may reduce the workload of manual inspection (i.e., manual inspection to see if there are set defects in the lens) for manual sampling or manual full inspection of the lens where the machine inspection has not detected any defects.

[0111] In the example where a plurality of wiped lens detection points are provided in the wiped lens detection device, a lens rotating assembly for wiped lens detection may also be included, which moves the lens on one wiped lens detection point to an adjacent next wiped lens detection point by rotating the lens rotating assembly.

[0112] In one example of the lens rotating assembly for wiping the lens, Figure 1 , 2 , 3, and 4, it includes a wiped lens detection rotary driver (not shown) and a wiped lens detection lens rotary shaft 304. The wiped lens detection lens rotary shaft 304 is coaxially provided with a wiped lens detection lens support platform 301.

[0113] During operation, the wiped lens detection rotating driver drives the wiped lens detection lens rotating shaft 304 to rotate, and the wiped lens detection lens support platform 301 rotates along with the wiped lens detection lens rotating shaft 304. The lens a on the wiped lens detection lens support platform 301 rotates to different wiped lens detection points 305 in sequence to be detected.

[0114] The arrangement of the rotating structure in the wiped lens detection device is conducive to arranging multiple wiped lens detection points in a relatively small space. Figure 1 , 2As shown in FIGS. 3 and 4 , two wiped lens detection points 305 are arranged on the wiped lens detection device.

[0115] Another embodiment of the lens inspection machine of the present invention further includes a device for removing the inspected lens.

[0116] The detected lens moving-out device is responsible for moving the detected lens out to a designated area. The specific structure of the detected lens moving-out device is as follows.

[0117] Detected lens removal device As an example of the detected lens removal device, Figure 1 , 2 As shown in FIGS. 3 and 4 , the detected lens moving-out device 400 comprises a detected lens moving-out shift arm 410 and a detected lens moving-out catch and place assembly. The detected lens moving-out catch and place assembly is arranged at the output end of the detected lens moving-out shift arm 410 .

[0118] During operation, the detected lens removal shift arm 410 drives the detected lens removal grab and place assembly to a specified position (such as a position where the lens needs to be extracted, or a position where the lens needs to be placed), and then the lens is grabbed or released by the detected lens removal grab and place assembly.

[0119] The detected lens moving-out shift arm 410 is a mechanical arm device, and a corresponding structure having the function of operating in one-dimensional, two-dimensional or three-dimensional directions can be set as needed.

[0120] An example of a shift arm of any dimension in the shift arm for moving out the detected lens may include a one-dimensional shift driver for moving out and a linear conveying structure for moving out. When working, under the drive of the one-dimensional shift driver for moving out, the shift arm of another dimension connected to the output end of the linear conveying structure for moving out is connected to move forward or backward along the one-dimensional direction.

[0121] An example of the linear removal conveying structure is as follows: Figure 1 , 2 , 3, and 4, including a linear removal drag chain 401, a linear removal guide rail 402, and a linear removal slider 403 slidably disposed on the linear removal guide rail 402, and the displacement arm in the other dimensional direction can be directly or indirectly disposed on the linear removal slider 403. In another example, it can also be composed of a linear removal conveyor belt (not shown in the figure), a linear removal conveyor pulley (not shown in the figure), and a linear removal fastening component (not shown in the figure) fastened to the linear removal conveyor belt, and the displacement arm in the other dimensional direction can be directly or indirectly disposed on the linear removal fastening component.

[0122] An example of a pick-and-place assembly for removing the detected lens is shown in FIG. Figure 1 , 2 , 3, and 4, including a pick-and-place vacuum suction device 421 for removal and a vacuum generator for removal (not shown in the figure). It utilizes the vacuum adsorption principle to realize the operation of grabbing and releasing the lens a through the pick-and-place vacuum suction device 421 for removal. In order to improve the grabbing efficiency, in another example, the number of the pick-and-place vacuum suction devices 421 for removal is several and arranged in a row or a column, and the intervals between the pick-and-place vacuum suction devices 421 for removal are adapted to the intervals of the lenses to be grabbed, so that the purpose of grabbing or releasing multiple lenses at one time can be achieved.
