Description

Technical Field

[0001] The present invention relates to the technical field of lens sorting, in particular to a myopia and presbyopia lens detection and sorting device and method. Background Art

[0002] A lens sorting machine is an advanced automated device. It mainly relies on the optical properties of lenses such as diopter, focal length, etc., as well as other physical properties such as thickness, weight, etc. Through a precise optical detection system, it emits light and analyzes its refraction, reflection or imaging conditions. Combined with the feeding unit in the mechanical structure to orderly convey the lenses, the detection unit makes an accurate judgment, and then the sorting unit quickly and accurately classifies and places the lenses according to standards such as degree, type, size, material, etc. It is widely used in links such as glasses production, lens processing and glasses store recycling, greatly improving the efficiency and accuracy of lens sorting and reducing labor costs.

[0003] In the sorting operation of myopia lenses and presbyopia lenses, due to the obvious characteristics of high-degree myopia lenses with thinner middle and thicker edges, it is not easy to cause stacking damage when directly stacking them; for low-degree myopia lenses, the thickness difference between the middle and the edges is smaller, and the middle area of presbyopia lenses is convex. Direct stacking of the above two types of lenses will cause stacking damage. Therefore, in the lens sorting operation, how to effectively avoid lens stacking damage is a technical problem that urgently needs to be solved. Summary of the Invention

Detailed Embodiments

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention in conjunction with the attached drawings of the specification.

[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be implemented in other ways different from this description. The so-called "embodiment" herein refers to specific features, structures, or characteristics that may be included in at least one implementation manner of the present invention. Embodiment 1

[0029] Referring to Figures 1 to 4 and Figure 9 , this embodiment provides a myopia and presbyopia lens detection and sorting device, which specifically includes a detector 1 for detecting corresponding parameters of the lens 3 and a sorter 2 for sorting and classifying the lens 3 according to the detection results; the detector 1 includes a lens supply belt 101, a lens conveyor belt 102, and a first transfer mechanism for transferring the lens 3 on the lens supply belt 101 to the lens conveyor belt 102, and also includes several parameter detection devices 103, a supply mechanism for supplying cup holders, and a conveying mechanism 105 communicating with the sorter 2; the sorter 2 includes a three-axis manipulator 201, a temporary storage bin 202, a cup holder 203, a cup holder supply belt 204, and a cup holder conveyor belt 205; the three-axis manipulator 201 is used to grab the lens 3 on the conveying mechanism 105 and temporarily stack it in the temporary storage bin 202. When a group of lenses 3 is stacked to a preset height, the three-axis manipulator 201 simultaneously grabs the group of lenses 3 and transfers them to the cup holder 203.

[0030] The supply mechanism includes a cup holder supply belt 1041. A cup holder transfer mechanism is provided on one side of the cup holder supply belt 1041. A second transfer mechanism for transferring the detected lens 3 to the conveying mechanism 105 is provided at one end of the lens conveyor belt 102. The cup holder is an integrated cup holder 5. The integrated cup holder 5 includes a disc base 501 and several support blocks 502 provided on the edge of the disc base 501. One side of the support block 502 facing the center of the disc base 501 is an inclined surface, and the other side of the support block 502 has a notch. A cavity 503 is provided at the bottom of the integrated cup holder 5.

[0031] The detector 1 is used to detect corresponding parameters of the lens 3, such as thickness, diameter, and optical power. The first transfer mechanism, the second transfer mechanism, and the cup holder transfer mechanism are suction cup robotic arms. The suction cup robotic arm belongs to the prior art and will not be described in detail in this application. It is used to suck the lens 3 or the integrated cup holder 5 and transfer it to the corresponding position. Several round holes are provided in the temporary storage bin 202. A round rod can be inserted into the round hole. More than three round rods form a temporary storage area for stacking the lens 3.

[0032] The three-axis manipulator 201 classifies the lenses that have been inspected by the inspection machine 1 and places them into different temporary storage areas in sequence. When the lenses 3 in a certain temporary storage area are stacked to a preset height or quantity, stacking in this temporary storage area stops. Then, the three-axis manipulator 201 transfers the lenses 3 or the cup holders containing the lenses 3 in this temporary storage area to the cup rack 203. The cup rack 203 is conveyed by the cup rack supply belt 204 to the corresponding area for waiting. When the three-axis manipulator 201 transfers a group of lenses 3 to the cup rack 203, the cup rack supply belt 204 continues to convey and transfers the cup rack 203 onto the cup rack conveyor belt 205, and then subsequent conveyance is carried out through the cup rack conveyor belt 205.

[0033] When inspecting and sorting myopia lenses, the integrated cup holder 5 and the cup holder supply belt 1041 are not required. After the thickness, diameter, and optical power of the lenses are inspected in sequence on the lens conveyor belt 102, the second transfer mechanism then transfers the lenses 3 to the conveyor mechanism 105. When inspecting and sorting hyperopia lenses and low-degree myopia lenses, the integrated cup holder 5 and the cup holder supply belt 1041 are required. The cup holder transfer mechanism transfers the integrated cup holder 5 on the cup holder supply belt 1041 to the conveyor mechanism 105 and stops at a preset position to wait for the second transfer mechanism to place the lenses 3 into the integrated cup holder 5. Embodiment 2

[0034] Refer to Figures 5 to 8 In this embodiment, the difference from Embodiment 1 is that the supply mechanism includes cup holder storage boxes 1042 symmetrically arranged on both sides of the lens conveyor belt 102. The cup holder is a split cup holder 4, and the split cup holder 4 is a semi-circular ring structure composed of two parts that can be joined together, can wrap around the outer edge of the lens 3 and open inward. Below the cup holder storage box 1042, there is a push plate mechanism 106 for pushing the split cup holders 4 to be joined together. The two ends of the cup holder storage box 1042 are open, and the upper part is used for loading the split cup holders 4, and the lower part is connected to the push plate mechanism 106. The top of the push plate mechanism 106 is provided with a groove 1061 having the same shape and size as the split cup holder 4. When the push plate mechanism 106 pushes out the split cup holder 4 in the groove 1061 and the push plate mechanism 106 resets, the lowermost split cup holder 4 in the cup holder storage box 1042 above the push plate mechanism 106 falls into the groove 1061.

[0035] The parameter detection device 103 includes two detection contacts 107 respectively located above and below the lens conveyor belt 102, and a soft support sleeve 108 is provided on the detection contact 107 located below the lens conveyor belt 102. One of the cup holder storage boxes 1042 is fixedly connected to the side wall of the lens conveyor belt 102, and the other cup holder storage box 1042 is fixedly connected to the side wall of the parameter detection device 103. The split cup holder 4 is provided with a plug 401 and a jack 402 matching the plug 401. It also includes a label mechanism for printing labels and attaching them to the lenses 3, and the split cup holder 4 is provided with a protrusion cooperating with the label mechanism.

[0036] In this embodiment, the setting of the protrusion facilitates the label mechanism to split the split cup holder 4 in the assembled state. The conveying mechanism 105 is connected to the end of the lens conveyor belt 102. The radial cross-section of the split cup holder 4 is approximately semi-circular ring-shaped, and there is a certain gap at the splicing joint of the assembled split cup holder 4 to adapt to the change in the diameter of the lens 3, ensuring that the assembled split cup holder 4 firmly holds the lens 3 to achieve a positioning effect and facilitating subsequent parameter detection. The edge of the split cup holder 4 close to the center of the semi-circular ring is made of a soft material, such as rubber, which has a slight deformation ability to adapt to the change in the thickness of the lens 3.

[0037] A fixed plate is arranged in the cup holder storage box 1042 to form a space area in the cup holder storage box 1042 with the same shape as the split cup holder 4, facilitating the neat placement of the split cup holder 4. Since the split cup holder 4 is approximately semi-circular ring-shaped, the split cup holder 4 placed in the cup holder storage box 1042 will not have a radial offset, ensuring that the subsequent split cup holder 4 can be successfully assembled. The depth of the groove 1061 is the same as or slightly less than the thickness of the split cup holder 4. The bottom surface of the cup holder storage box 1042 is flush with the top surface of the push plate mechanism 106, and the side of the split cup holder 4 is closely attached to the cup holder storage box 1042. When the push plate mechanism 106 moves to make the groove 1061 completely coincide with the hollow area at the bottom of the cup holder storage box 1042 and there is no split cup holder 4 in the groove 1061, the lowermost split cup holder 4 in the cup holder storage box 1042 drops into the groove 1061. When the groove 1061 does not completely coincide with the hollow area at the bottom of the cup holder storage box 1042, the lowermost split cup holder 4 in the cup holder storage box 1042 is supported by the side wall of the cup holder storage box 1042 and the top of the push plate mechanism 106 with a sufficient large supporting force, and the split cup holder 4 does not drop downward.

[0038] The cup holder storage box 1042 is fixed relative to the push plate mechanism 106, and there is only contact between the two. The push plate mechanisms 106 on both sides of the lens conveyor belt 102 are driven by a motor to move closer to or away from each other. When the push plate mechanisms 106 move closer to each other, the split cup holders 4 in their respective grooves 1061 are driven to fit together. At the same time, the detection contact 107 below the lens conveyor belt 102 is driven to rise. The soft support sleeve 108 is sleeved outside the detection contact 107, and the end of the soft support sleeve 108 first contacts the lens 3 and lifts the lens 3 to a certain height. The soft support sleeve 108 is made of rubber with a certain supporting force, and during this process, the soft support sleeve 108 does not deform, so as not to affect the fitting process of the split cup holders 4 and place the lens 3 in the fitted split cup holders 4. The above detection contact 107 continues to rise by a certain height, and during this process, the soft support sleeve 108 also does not deform, so that the split cup holders 4 are separated from the push plate mechanism 106 as a whole. At the same time, the motor drives the push plate mechanism 106 to return to its initial position, and then the detection contact 107 is lowered so that the split cup holders 4 are placed on the lens conveyor belt 102. Then, the detection contact 107 above the lens conveyor belt 102 is driven to press against the top of the lens 3, and then the detection contact 107 below the lens conveyor belt 102 is driven to rise, causing the soft support sleeve 108 to deform, and finally making the detection contact 107 contact the bottom of the lens 3 to realize the detection of the lens 3.

[0039] When detecting and sorting hyperopia lenses and low-degree myopia lenses, the conveying mechanism 105 is connected to the end of the lens conveyor belt 102, and the cup holder storage box 1042 is located on both sides of the lens conveyor belt 102. Embodiment III

[0040] This embodiment provides a method for detecting and sorting myopia and presbyopia lenses, including the following steps:

[0041] Step 1, connect the detection machine 1, the sorting machine 2, and the labeling mechanism in sequence, complete the system assembly, debugging, and self-check, start the lens supply belt 101 to convey the lenses 3, and transfer the lenses 3 from the lens supply belt 101 to the lens conveyor belt 102 by the first transfer mechanism;

[0042] Step 2, detect the corresponding parameters of the lenses 3 on the lens conveyor belt 102;

[0043] Step 3, determine whether the integrated cup holder 5 needs to be used according to the degree of the lens 3. Generally speaking, when stacking myopia lenses with a degree between 0 and -0.25 directly and all presbyopia lenses, there will be a phenomenon of intermediate contact wear, so it is necessary to add an isolation device (cup holder) at the edge of the lens 3 to separate adjacent lenses 3.

[0044] When the integrated cup holder 5 is not needed, directly proceed to Step Four. When the integrated cup holder 5 is needed, start the cup holder supply belt 1041, and then transfer the integrated cup holder 5 to a preset position on the conveying mechanism 105 through the cup holder transfer mechanism and wait;

[0045] Step Four: Transfer the lens 3 to a preset position on the conveying mechanism 105 through the second transfer mechanism, and then convey the lens 3 or the integrated cup holder 5 carrying the lens 3 to the sorting machine 2 through the conveying mechanism 105;

[0046] Step Five: The sorting machine 2 sorts and classifies the lenses 3 according to the corresponding parameters of the lenses 3, and then transfers them to the labeling mechanism for labeling. Example Four

[0047] This example provides a method for detecting and sorting myopia and presbyopia lenses, including the following steps:

[0048] Step One: Start the lens supply belt 101 to convey the lenses 3, and transfer the lenses 3 from the lens supply belt 101 to the lens conveyor belt 102 by the first transfer mechanism;

[0049] Step Two: Place the split cup holders 4 into the cup holder storage boxes 1042 on both sides of the lens conveyor belt 102. When the lens 3 is conveyed to the parameter detection device 103, start the detection contact 107 located below the lens conveyor belt 102, drive the soft support sleeve 108 to lift the lens 3 to a height corresponding to the bottom of the push plate mechanism 106, and then start the push plate mechanism 106 to drive the split cup holders 4 to be assembled;

[0050] Step Three: Lift the lens 3 up by a certain height to make the assembled split cup holders 4 rise, and then reset the push plate mechanism 106;

[0051] Step Four: Detect the corresponding parameters of the lens 3, and convey the split cup holders 4 carrying the lens 3 to the sorting machine 2 through the conveying mechanism 105;

[0052] Step Five: The sorting machine 2 sorts and classifies the lenses 3 according to the corresponding parameters of the lenses 3, and then transfers them to the labeling mechanism for labeling.

[0053] Importantly, although only a few embodiments are described in detail in this disclosure, those skilled in the art who refer to this disclosure should readily understand that many modifications are possible without materially departing from the subject matter described in this application, such as the dimensions, structures, shapes, and proportions of various elements, as well as temperature, pressure, installation arrangements, use of materials, color, orientation changes, etc.; for example, an element shown as integrally formed may be composed of multiple parts or elements, and the position of the element may be inverted or otherwise changed; accordingly, all such modifications should be included within the scope of the present invention, and other substitutions, modifications, changes, and omissions may be made in the design, operating conditions, and arrangements of the exemplary embodiments without departing from the scope of the present invention.
