[0021] Reference Figures 1 to 5 As shown, the present utility model discloses a glass stripe light detection device. According to a specific embodiment, it includes a conveying bed frame 1 for conveying the glass to be inspected and a driving roller 2 inside the conveying bed frame 1;

[0022] A lofting mechanism 5 is installed on the conveying bed frame 1. The lofting mechanism 5 includes a positioning member and a lofting frame which are connected to each other. The positioning member is used to accurately place the glass stripe standard sheet 7 at the detection position, and the lofting frame is used to lap the glass stripe standard sheet 7 to prevent displacement or falling off during the detection process;

[0023] The glass stripe standard sheet 7 is used to calibrate, inspect or evaluate the performance and accuracy of the glass stripes. Such standard sheets should contain known and precise stripe patterns for comparative analysis with the detection results.

[0024] A glass stripe detection light source, located above the conveying bed frame 1, provides light irradiation to the glass to be inspected and the glass stripe standard sheet 7;

[0025] Furthermore, the glass stripe detection light source includes a light strip board 4; the light strip board 4 is formed by arranging a plurality of lamp beads along a flexible circuit board, which can be flexibly bent and cut to adapt to different installation environments and shape requirements to meet the requirements of the glass stripe detection light source;

[0026] The light strip board 4 is installed at the upper end of the vertical board 3 arranged outside the conveying bed frame 1;

[0027] The light sources for glass stripe detection usually include: (1) parallel light sources such as stripe projectors, interferometers, etc.; (2) LED light sources; (3) laser light sources; (4) xenon lamp light sources. In the present utility model, a xenon lamp is adopted. The xenon lamp has the advantages of high brightness, high color temperature, long service life, etc., and can provide a stable and strong light source. By adjusting the distance and angle between the light source and the glass, the stripe situation on the glass surface can be clearly observed.

[0028] The positioning member can lift and lower the lofting frame through the lifting mechanism, and is used to accurately lift and lower the glass stripe standard piece 7 to the detection position.

[0029] Thus, the glass stripe standard piece 7 lapped on the lofting frame and the glass to be inspected irradiated by the glass stripe detection light source are compared and analyzed with the detection results.

[0030] Reference Figures 1 to 5 As shown in the figure, in some specific embodiments, the lifting mechanism includes a lifting frame 55. One end of the lifting frame 55 is connected to the lifting transmission member, and the other end is connected to the lofting frame;

[0031] In a further embodiment, the lifting transmission member includes a lead screw 53 and two limit rods 54 symmetrically centered on the lead screw 53. The lead screw 53 is threadedly sleeved with the lifting frame, the lifting frame is sleeved with the two limit rods 54, and the lead screw 53 is connected to the driving member.

[0032] In a further embodiment, a protective box 51 is arranged outside the conveying bed frame 1. A lead screw 53 and two limit rods 54 symmetrically centered on the lead screw 53 are arranged inside the protective box 51. The driving member is a servo motor 52, and the output end of the servo motor 52 passes through the top plate of the protective box 51 and is fixedly connected to the upper end of the lead screw 53.

[0033] A fixed box 8 is fixedly connected to the outside of the conveying bed frame 1 through bolts, and the protective box 51 is installed on the fixed box 8.

[0034] Reference Figures 1 to 5 As shown in the figure, in some specific embodiments, the lofting frame includes a fixing plate 57 connected to the lifting frame 55. Side rails 56 are symmetrically installed on both sides of the fixing plate 57. Sliders 58 are arranged inside the two side rails 56, and a support plate 59 is fixedly installed between the two sliders 58. The glass stripe standard piece 7 is lapped on the support plate 59.

[0035] Furthermore, the side rails 56 symmetrically installed outside the fixing plate 57 are slidably connected to the inside of the protective box 51 through the lifting frame 55, and the support plate 59 is slidably connected to the inside of the side rails 56 through the sliders 58 installed on both sides.

[0036] Thus, the fixed plate 57, the two side rails 56, the two sliders 58 and the support plate 59 form a lofting frame for the glass stripe standard sheet 7 to lap; when the glass to be inspected is directly below the light strip board 4, the glass stripe standard sheet 7 is beside the glass product, which facilitates the staff to visually observe the stripe difference between the glass to be inspected and the glass stripe standard sheet 7.

[0037] Reference Figure 3 、 Figure 5 As shown in the figures, in some specific embodiments, L-shaped handle parts 6 are symmetrically installed at the ends of the support plate 59, which facilitates the placement and replacement of the glass stripe standard sheet 7.

[0038] Reference Figure 1 As shown in the figures, in some specific embodiments, a height difference is left between the lofting frame and the uniformly arranged driving rollers 2 for the glass to be inspected to continue to be conveyed below the lofting frame. When the output end of the servo motor 52 rotates forward, the lifting frame 55 will be driven downward by the lead screw 53 to approach the glass to be inspected for convenient observation. When the output end of the servo motor 52 rotates in the reverse direction, the lifting frame 55 will be lifted upward away from the glass, and at this time, it is convenient for the staff to hold the handle part 6 below the support plate 59.

[0039] When the utility model is in use, the vertical plate 3 and the fixed box 8 are installed on the same side of the conveying bed frame 1. When the glass to be inspected is conveyed to directly below the light strip board 4 by the driving rollers 2, the xenon lamp irradiates the glass to be inspected below, and the staff stands on the side far from the protection box 51. At this time, manually hold the handle part 6 below the support plate 59, pull out the support plate 59 outward, place the adapted glass stripe standard sheet 7 on the support plate 59, then push the support plate 59 back to its original position. The output end of the servo motor 52 is fixed to the upper end of the lead screw 53. When the output end of the servo motor 52 rotates forward, the lifting frame 55 is driven downward by the lead screw 53 to approach the glass to be inspected, and there is no blockage between the lofting frame and the glass to be inspected, and there is a height difference between the lofting frame and the glass to be inspected. After the staff compares and observes through the glass stripe standard sheet 7 on the lofting frame, the glass product can continue to be conveyed below the lofting frame.
