[0004] When the above-mentioned existing bubble detection device for optical glass is actually used, its light incident angle is fixed and cannot adapt to the scattering characteristics of different defects (for example, 30° incidence is sensitive to transverse cracks, and 60° is effective for longitudinal pores). The missed detection rate is as high as 40%. Therefore, the existing bubble detection device for optical glass is difficult to effectively realize accurate detection of bubbles in optical glass.

[0010] Preferably, the guide rod is fixed on the light shielding plate symmetrically on the left and right, and the light shielding plate cooperates with the front end opening of the dark box to achieve sealing, and a carrier is fixed on the light shielding plate.

At the same time, the rotation angle of the vertical plate is 0-60°. Through the above structure, a basic force can be provided for the rotation of multiple rotating shafts and reflectors.

[0014] Preferably, a gear is also fixed on the rotating shaft, and the gear is engaged with the tooth block on the convex gear rod to realize transmission, wherein the gear rotates at an angle of 5° each time, and the tooth blocks on the convex gear rod are distributed at equal intervals, and the convex gear rod is symmetrically fixed on the connecting frame on the left and right, the upper end face of the connecting frame is flush with the upper end face of the dial plate, and the connecting frame is slidably connected to the cross bar fixed on the lower end face of the dark box, and a second spring is fixed between the connecting frame and the dark box.

[0015] Preferably, the second adjustment mechanism includes a vertical rod with one end fixed to the infrared sensor, and the other end of the vertical rod is fixed to the fixed frame.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This new material bubble detection device for optical glass uses a linked first adjustment mechanism. During the bubble detection process, the infrared lamp emits light at an intermittent angle, thereby achieving intermittent adjustment of the light incident angle. Combined with the divergence of the incident light by bubbles inside the glass, adjusting the incident angle optimizes the refraction path of the light at the bubble edge, amplifying the degree of light deflection, thereby highlighting the bubble outline and ensuring the accuracy of the test data.

[0020] 2. This new material bubble detection device for optical glass adopts a linked second adjustment mechanism, which can synchronously adjust the distance between the infrared sensor and the glass while intermittently adjusting the incident angle of the light, thereby achieving optical path offset compensation, thereby avoiding ensuring that the infrared sensor can accurately receive the infrared light reflected by the glass, and further ensuring the accuracy of the detection data.

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1-9The present invention provides a technical solution: a bubble detection device for new material optical glass, comprising a main body 1, a cylinder 2 fixed to the rear end surface of the main body 1, a dark box 5 installed in the main body 1, a transfer mechanism 3 for moving the glass fixed to the output end of the cylinder 2, a carrier 4 installed on the transfer mechanism 3 for positioning the glass, an infrared lamp 7 provided on the lower side of the dark box 5, and an infrared sensor 8 provided on the upper side of the dark box 5;

[0033] The first adjustment mechanism 6 is used to achieve intermittent adjustment of the angle of the infrared lamp 7. The first adjustment mechanism 6 is installed on the dark box 5;

[0034] The second adjusting mechanism 9 is used to adjust the height of the infrared sensor 8 . The second adjusting mechanism 9 is connected to the infrared sensor 8 , and the second adjusting mechanism 9 is connected to the first adjusting mechanism 6 .

[0035] The transplanting mechanism 3 includes a movable plate 301 fixed to the output end of the cylinder 2, and a shift plate 302 is fixed to the movable plate 301 symmetrically. The movable plate 301 is slidably connected to the guide rod 303, and a first spring 305 is fixed between the movable plate 301 and the guide rod 303; the guide rod 303 is symmetrically fixed to the light shielding plate 304, and the light shielding plate 304 cooperates with the front opening of the dark box 5 to achieve a seal, and the light shielding plate 304 is fixed to the carrier 4; the guide rail 401 is symmetrically fixed to the carrier 4, and the guide rail 401 is slidably connected to the dark box 5;

[0036] When using the new material optical glass bubble detection device, Figures 1-9 As shown, the optical glass to be inspected is first placed on the carrier 4, and then the cylinder 2 is controlled to contract, thereby driving the movable plate 301 to move. At this time, due to the limiting effect of the first spring 305, the guide rod 303, the light shielding plate 304 and the carrier 4 are moved into the dark box 5, so that the optical glass can be moved into the dark box 5 for subsequent inspection. In addition, during the movement of the carrier 4, the sliding guide effect between the guide rail 401 and the dark box 5 can ensure the stability of the movement of the carrier 4 and the optical glass.

[0037] The first adjustment mechanism 6 includes a rotating shaft 601 connected to the dark box 5 with equally spaced bearings, and a reflector 602 is fixed between the left and right rotating shafts 601, and an infrared lamp 7 is fixed inside the reflector 602, and the infrared lamp 7 is located below the carrier 4; a vertical plate 603 is also vertically fixed on the rotating shaft 601, and a connecting rod 604 is connected between two adjacent vertical plates 603, and the connecting rod 604 is rotatably connected to the vertical plate 603, and the rotation angle of the vertical plate 603 is 0-60°; the rotating shaft A gear 605 is also fixed on 601, and the gear 605 meshes with the tooth block on the convex gear rod 606 to realize transmission. The gear 605 rotates at an angle of 5° each time, and the tooth blocks on the convex gear rod 606 are evenly spaced. At the same time, the convex gear rod 606 is fixed to the connecting frame 607 symmetrically. The upper end surface of the connecting frame 607 is flush with the upper end surface of the dial plate 302, and the connecting frame 607 is slidably connected to the crossbar 608 fixed to the lower end surface of the dark box 5. At the same time, a second spring 609 is fixed between the connecting frame 607 and the dark box 5.

[0038] During the movement of the light shielding plate 304, Figures 1-9 As shown, when the shading plate 304 contacts the end of the dark box 5, the front opening of the dark box 5 can be sealed, so that the glass is in the sealed space formed by the dark box 5 and the shading plate 304. At this time, the dial plate 302 is just in contact with the connecting frame 607. Then, the infrared light emitted by the infrared lamp 7, in conjunction with the infrared sensor 8, can detect the position of bubbles inside the glass. Since bubbles refract infrared light at different angles, the infrared sensor 8 cannot detect the infrared light at the corresponding position, thereby determining whether bubbles exist and the location of the bubbles.

[0039] After the light shielding plate 304 contacts the dark box 5, the cylinder 2 continues to retract. Since the position of the light shielding plate 304 is limited, the cylinder 2 retracts and drives the movable plate 301 to move backward relative to the light shielding plate 304. The sliding guiding effect between the movable plate 301 and the guide rod 303 can ensure the stability of the movement of the movable plate 301. At this time, the first spring 305 is forced to retract, and the movable plate 301 moves backward relative to the light shielding plate 304, synchronously driving the dial plate 302 to move backward, so that the dial plate 302 provides a force on the connecting frame 607, thereby moving the connecting frame 607 backward. The sliding guiding effect between the connecting frame 607 and the cross bar 608 can ensure the stability of the movement of the connecting frame 607. When the connecting frame 607 moves backward, it synchronously drives the convex gear rod 606 to move backward. When the tooth block on the convex gear rod 606 engages with the gear 605 for transmission, At this time, the gear 605 is forced to rotate, thereby synchronously driving the rotating shaft 601 to rotate. Cooperating with the transmission effect of the connecting rod 604, the multiple rotating shafts 601 can be rotated synchronously, thereby driving the multiple reflectors 602 to rotate. Through the rotation of the reflector 602, the angle of the infrared light emitted by the infrared lamp 7 can be adjusted, thereby achieving the adjustment of the infrared incident angle. When the tooth block on the convex gear rod 606 is separated from the gear 605, the reflector 602 stops rotating, and the reflector 602 rotates by 5° each time. Through the meshing transmission of the multiple sets of tooth blocks on the convex gear rod 606 and the gear 605, the reflector 602 can be rotated intermittently, thereby achieving intermittent adjustment of the infrared incident angle, thereby achieving multi-angle detection. The maximum rotation angle is 60°, so as to better meet the detection function and ensure the accuracy of the detection data.

[0040] The second adjustment mechanism 9 includes a vertical rod 901 fixed to the infrared sensor 8 at one end, and the other end of the vertical rod 901 is fixed to the fixing frame 902, and the vertical rod 901 is slidably connected to the dark box 5; a sliding groove rod 903 is fixed to the fixing frame 902, and the sliding groove rod 903 is slidably connected to the convex shaft 904, and the convex shaft 904 is fixed to the disk 905, and the disk 905 is fixed to the rotating shaft 601; the disk 905 contacts the rubber plate 906 to achieve a positioning effect, and the contact surface between the rubber plate 906 and the disk 905 is a rough structure, and the rubber plate 906 and the sliding rod 907 are fixed by bolts, and the sliding rod 907 is slidably connected to the side plate 908, the side plate 908 is fixed to the outside of the dark box 5, and a third spring 909 is fixed between the side plate 908 and the sliding rod 907;

[0041] When the rotating shaft 601 rotates intermittently, Figures 1-9As shown, the synchronous disc 905 and the convex shaft 904 rotate intermittently. When the convex shaft 904 rotates, the sliding action between the convex shaft 904 and the slide rod 903 can drive the fixed frame 902 to move downward intermittently under force. The sliding action between the vertical rod 901 and the dark box 5 can ensure the stability of the movement of the fixed frame 902. When the fixed frame 902 moves downward, the vertical rod 901 and the infrared sensor 8 are synchronously driven to move downward, thereby reducing the distance between the infrared sensor 8 and the optical glass, thereby achieving optical path offset compensation, ensuring that when the incident angle of the infrared light is tilted, the infrared sensor 8 can still receive the infrared light, and according to the above principle, the greater the tilt of the incident angle of the infrared light, the smaller the distance between the infrared sensor 8 and the optical glass, thereby effectively ensuring the normal detection.

[0042] During the detection process, when the tooth block on the convex gear rod 606 engages with the gear 605, causing the rotating shaft 601 and the disk 905 to rotate under force, the rotation force of the disk 905 is greater than the friction between the disk 905 and the rubber plate 906, thereby ensuring the normal rotation of the rotating shaft 601 and the disk 905. When the tooth block on the convex gear rod 606 engages and disengages from the gear 605, the third spring 909 provides a force for the sliding rod 907 and the rubber plate 906, which, in conjunction with the friction between the rubber plate 906 and the disk 905, can achieve automatic positioning, ensure the stability of the device after intermittent adjustment of the angle, and thus ensure the normal progress of the detection.
