[0002] Glass is a transparent medium material and is an isotropic optical material after float annealing. However, after tempering / semi-tempered glass, since the equipment cannot achieve absolutely uniform heating and cooling, unevenly distributed stress will form inside the glass, making the glass anisotropic. At this stage, it is impossible to completely eliminate the stress spots in tempered glass. The only way to make the stress distribution of tempered glass more uniform is to adjust the process and equipment.

[0003] After searching, the Chinese patent publication number CN213843064U discloses a tempered glass stress spot detection light box, including an LED light strip and a polarizing plate respectively located on both sides of a printed glass pad; the LED light strip is arranged vertically, and the printed glass pad is inclined relative to the LED light strip, forming an angle α between the two, and the light emitted by the LED light strip illuminates the printed glass pad; the polarizing plate is kept parallel to the printed glass pad and is laid on the printed glass pad, the tempered glass to be detected leans on the polarizing plate, and the tempered glass and the LED light strip form an angle β; the angle α and the angle β are both acute angles and the same size.

[0004] The device in the above patent has the following shortcomings: when observing, there may be blurred stress spots at local locations of the tempered glass, and the LED strip cannot concentrate the light source to illuminate the area, making it difficult for the operator to clearly see the stress spots, increasing the difficulty of observation. Utility Model Content

[0008] In order to facilitate illuminating the transparent plate, preferably, a connecting plate is fixedly connected to the working box, a reflective lampshade is fixedly connected to the connecting plate, a lighting lamp is provided in the reflective lampshade, and the lighting lamp faces the transparent plate.

When workers wear polarizing glasses to observe, they can carefully observe the stress spots that may be blurred in local positions of the tempered glass, allowing operators to clearly see the stress spots and reducing the difficulty of observation.

[0015] 2. The tempered glass stress spot detection light box can evenly distribute the direct light emitted by the light source through the diffusion filter, thereby reducing the appearance of light spots and shadows, providing more uniform lighting, and reducing the strong light spots caused by reflections on the tempered glass surface.

[0026] The tempered glass to be tested for stress spots is placed between the support plate 4 and the transparent plate 2, and leaned against the diffusion filter 3. The diffusion filter 3 can evenly distribute the direct light emitted by the light source, thereby reducing the appearance of light spots and shadows, providing more uniform lighting, and reducing the strong light spots caused by reflections on the tempered glass surface. This helps to observe subtle changes in stress spots and avoid interference caused by reflections that affect the test results.

[0027] The models of the direct lamp 17 can be JHB-ABX80-95C or JHB-ABX100-120C. Direct lamps 17 with different specifications and parameters can be used according to the specifications of the tempered glass to adapt to different usage scenarios and needs. The direct lamp 17 can move up and down, left and right in the work box 1 to focus on irradiating different positions of the tempered glass, so that when the staff wears polarizing glasses for observation, they can carefully observe the blurred stress spots that may exist in the local position of the tempered glass, so that the operator can clearly see the stress spots, reducing the difficulty of observation.

By rotating the locking bolt 6 counterclockwise, the limit pad 7 can be rotated and away from the tempered glass.

[0030] In addition, a connecting plate 14 is fixedly connected in the working box 1 , a reflective lampshade 15 is fixedly connected to the connecting plate 14 , and a lighting lamp 16 is arranged in the reflective lampshade 15 , and the lighting lamp 16 faces the transparent plate 2 .

[0033] In addition, a motor is provided on the working box 1, and the transverse screw rod 9 and the longitudinal screw rod 12 are respectively fixedly connected to the output end of the motor.

[0034] Reference Figure 4 When the motor drives the horizontal screw rod 9 to rotate clockwise, the horizontal movable block 10 will move from the left side to the right side of the working box 1, and the longitudinal box 11 will move to the right synchronously. When the motor drives the horizontal screw rod 9 to rotate counterclockwise, the horizontal movable block 10 will move from the right side to the left side of the working box 1, and the longitudinal box 11 will move to the left synchronously, thereby changing the horizontal position of the direct light 17.

[0035] When the motor drives the longitudinal screw rod 12 to rotate clockwise, the longitudinal movable block 13 will move from the top to the bottom of the working box 1, and the longitudinal box 11 will move downward synchronously. When the motor drives the longitudinal screw rod 12 to rotate counterclockwise, the longitudinal movable block 13 will move from the bottom to the top of the working box 1, and the longitudinal box 11 will move upward synchronously, thereby changing the longitudinal position of the direct lamp 17.
