Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for lens processing, in particular to a detection and turning device for rough grinding and feeding of lenses. Background Technique

[0002] As is known, optical lenses are made by grinding optical glass according to the designed focal length by a grinding device; in the existing lens grinding, generally one surface of the lens is ground first, and then the other surface of the lens is ground. Whether the concave surface of the lens is rough ground first and then the convex surface of the lens is rough ground; or the convex surface of the lens is rough ground first and then the concave surface of the lens is rough ground. It is necessary to detect the state of the lens surface before feeding, and then turn over the lens in the incorrect state to ensure that the concave surface or the convex surface of the lens to be fed faces up. The traditional method is to observe by the staff and then manually turn over the lens in the incorrect state. This method not only has low efficiency, but also because the lens is almost made of a fully transparent material, it is easy to cause eye fatigue of the staff, and there are often cases where the lens in the incorrect state is not turned over. Therefore, there is an urgent need for a device that can automatically detect whether the lens is in the incorrect state and turn over the lens in the incorrect state.

[0003] Therefore, we have designed a detection and turning device for rough grinding and feeding of lenses. Content of the Utility Model

[0004] In order to overcome the deficiencies in the background technique, the utility model discloses a detection and turning device for rough grinding and feeding of lenses.

[0005] To achieve the above invention purpose, the utility model adopts the following technical scheme:

[0007] A turning device is arranged at the position of the installation vertical plate corresponding to the upper part of the detection device, and a finger cylinder capable of clamping the lens located on the top of the detection end of the detection device is arranged at the turning part of the turning device, so as to turn over the lens in the incorrect state.

[0008] Preferably, a clamping bracket for clamping the detection device is provided at the lower section of the mounting vertical plate, and a support sleeve is provided above the clamping bracket and sleeved at the detection end of the detection device at intervals to stably support the lens.

[0012] The mounting vertical plate is further provided with a driving device capable of driving the slider to move up and down.

[0013] Preferably, protective parts are provided on the two finger parts of the finger cylinder.

[0014] Due to the adoption of the above technical solutions, the present utility model has the following beneficial effects:

[0015] 1. Due to the arrangement of the transverse moving device, the vertical moving device and the suction head, the lens to be detected can be transferred to the area to be detected, and the lens in the area to be detected can be transferred to the loading area.

[0016] 2.

Detailed implementation mode

[0022] The present utility model can be explained in detail through the following embodiments. The purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model. In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "front", "rear", "left", "right", etc. indicating the orientation or position relationship, it is only corresponding to the drawings of the present application for the convenience of describing the present utility model; it should be understood that if there are terms such as "end", "side", "end part", "side part", "horizontal", "longitudinal", etc. indicating the orientation or position relationship, it is only corresponding to the length and width of the corresponding component, that is, the "end part" indicates the head and tail areas in the length direction of the corresponding component, and the "side part" indicates the head and tail areas in the width direction of the corresponding component; it is for the convenience of describing the present utility model rather than indicating or implying that the device or element referred to must have a specific orientation.

[0023] Embodiment 1, in combination with the attached Figures 1-4 , a detection and flipping device for rough grinding and feeding of lenses, includes an installation vertical plate 1. At the lower end of one plate surface of the installation vertical plate 1, there is a detection device 2 with the detection end facing upwards; as needed, the detection device 2 can be a dial indicator, a displacement sensor, etc. At the upper end of one plate surface of the installation vertical plate 1, there is a horizontal moving device 3. The moving end of the horizontal moving device 3 is provided with a vertical moving device 4. The moving end of the vertical moving device 4 is provided with a horizontal installation plate 5. And at both ends of the horizontal installation plate 5, there are suction heads 6 that can adsorb the lenses and can correspond to the detection device 2, so that one suction head 6 places the adsorbed lens on the top of the detection end of the detection device 2, and the other suction head 6 removes the lens located on the top of the detection end of the detection device 2;

[0024] At the position of the installation vertical plate 1 corresponding to the upper part of the detection device 2, there is a flipping device 7. And on the flipping part of the flipping device 7, there is a finger cylinder 8 that can clamp the lens located on the top of the detection end of the detection device 2, so as to turn over the lens in the incorrect state.

[0025] The logic for detecting whether the lens is in the correct state in this utility model is as follows: Since one surface of the lens is concave and the other surface is convex. When the concave surface needs to face upward, when the lens in the correct state is placed above the detection end of the detection device 2, the convex surface of the lens presses down on the detection end of the detection device 2; when the lens in the incorrect state is placed above the detection end of the detection device 2, the concave surface of the lens presses down on the detection end of the detection device 2; and if the concave depression size and the convex protrusion size of the lens are both A, then the difference in the distance that the lens in the correct state presses down on the detection end of the detection device 2 and the distance that the lens in the incorrect state presses down on the detection end of the detection device 2 is 2A. Therefore, it is possible to determine whether the lens is in the correct state through the detection device 2.

[0026] As needed, when the detection and flipping device is specifically used, it can be connected to a control system. The control system controls whether the flipping device 7 and the finger cylinder 8 act according to the results detected by the detection device 2, realizing a working mode of continuous operation without manual participation. Specifically, how to connect the control system and the specific structure of the control system can adopt the electrical control in the prior art, and will not be specifically described here.

[0027] Before use, calibrate the detection device 2 first. Specifically, first place the lens in the correct state on the top of the detection device 2, and observe or set the detection result of the detection device 2 at this time as the reference.

[0028] As needed, protective parts 15 are provided at the two finger parts of the finger cylinder 8, which can prevent the two finger parts of the finger cylinder 8 from directly clamping the lens; as needed, the protective parts 15 can be asbestos layers or nylon plates; when the protective parts 15 are nylon plates, an arc matching the lens is provided at the position where the protective parts 15 clamp the lens.

[0029] In use, the first step: Start the vertical moving device 4. The vertical moving device 4 drives the two suction heads 6 to descend. At this time, one suction head 6 sucks the lens to be detected, and the other suction head 6 sucks the lens in the correct state on the top of the detection device 2. Then the vertical moving device 4 drives the two suction heads 6 to reset; The second step: Start the horizontal moving device 3. The horizontal moving device 3 drives the vertical moving device 4 to move, and then drives the two suction heads 6 adsorbed with lenses to move, so that the suction head 6 sucking the lens to be detected moves to directly above the detection device 2, and the other suction head 6 moves to the feeding area. Then start the vertical moving device 4. The vertical moving device 4 drives the two suction heads 6 to descend. At this time, the suction head 6 sucking the lens to be detected places the lens on the top of the detection device 2, and the other suction head 6 places the lens in the feeding area. Then the vertical moving device 4 and the horizontal moving device 3 are reset in sequence; The third step: When the detection result of the detection device 2 deviates greatly from the reference, start the finger cylinder 8. The finger cylinder 8 clamps the lens at the corresponding position, and then start the flipping device 7. The flipping device 7 drives the finger cylinder 8 to flip 180 degrees, that is, the flipping operation of the lens is completed, and then the finger cylinder 8 resets; The fourth step: Repeat the first step, the second step and the third step in a cycle.

[0030] It should be noted that: The horizontal moving device 3 and the vertical moving device 4 can adopt cylinders with lower prices and simple control logics; The flipping device 7 can adopt a motor or a rotary cylinder.

[0031] According to needs, to ensure the position accuracy of the vertical moving device 4 and prevent the position of the suction head 6 from shifting, a horizontal slide rail 11 slidably connected to the vertical moving device 4 is also provided on the upper section of the mounting vertical plate 1.

[0032] Furthermore, an installation plate slidably connected to the horizontal slide rail 11 can be installed on the moving part of the horizontal moving device 3, and the vertical moving device 4 is installed through the installation plate.

[0033] Embodiment 2, in combination with the attached Figure 1 、 3 A detection and flipping device for rough grinding and feeding of lenses. On the basis of Embodiment 1, in order to ensure that the lens on the top of the detection device 2 can be stably supported, a clamping frame 9 for clamping the detection device 2 is provided on the lower section of the mounting vertical plate 1, and a support sleeve 10 is provided above the clamping frame 9 and sleeved at intervals on the detection end of the detection device 2 to facilitate the stable support of the lens. Specifically, the outer diameter of the support sleeve 10 is smaller than the diameter of the lens; Such a setting can support the lens through the support sleeve 10, and can effectively prevent the lens from shifting in position, resulting in a decrease in detection accuracy, and further ensure the accuracy of the detection result.

[0034] Embodiment 3, in combination with the attached Figures 1-2, a detection and flipping device for rough grinding and loading of lenses. Based on Embodiment 1 or 2, to prevent the fingers of the finger cylinder 8 from squeezing the detection part of the detection device 2 during the process of flipping the lens, a telescopic device 12 coaxial with it is provided on the flipping part of the flipping device 7, and a finger cylinder 8 is provided at the telescopic end of the telescopic device 12; that is, before flipping the lens, by contracting the telescopic device 12, the lens and the finger part of the finger cylinder 8 can be moved away from the monitoring end of the detection device 2. At this time, when flipping the lens again, the finger part of the finger cylinder 8 will not touch the detection part of the detection device 2.

[0035] Embodiment 4, in combination with the attached Figures 3-4 , a detection and flipping device for rough grinding and loading of lenses, which is different from Embodiment 3 in that a vertical chute is provided at the lower section of the installation vertical plate 1, and a slider 13 is slidably connected to the vertical chute; the fixing part of the flipping device 7 is fixedly installed on the slider 13; the installation vertical plate 1 is also provided with a driving device 14 capable of driving the slider 13 to move up and down; that is, before flipping the lens, by driving the driving device 14 to drive the slider 13 to rise, and then driving the flipping device 7, the finger cylinder 8 and the lens to rise, so that the lens and the finger part of the finger cylinder 8 are moved away from the monitoring end of the detection device 2. At this time, when flipping the lens again, the finger part of the finger cylinder 8 will not touch the detection part of the detection device 2.

[0036] According to requirements, the driving device 14 can adopt a cylinder with a lower price and a simple control logic.
