[0004] However, existing inspection tools and inspection methods are unable to perform appearance inspections on the IR hole area, which can easily lead to defective products entering the market. Utility Model Content

[0005] In view of this, the present application provides an inspection light box fixture to solve the problem of insufficient means for appearance inspection of glass products with IR holes.

[0006] The present application provides a light box inspection fixture, including:

[0007] The light box body is constructed as a box structure, and the light box body includes a bottom wall and a side wall surrounding the bottom wall; two oppositely arranged first wall surfaces and two oppositely arranged second wall surfaces are connected end to end to enclose and form the side wall; the top of the light box body forms an opening;

[0008] A transparent carrier plate is arranged at the opening, and the transparent carrier plate is suitable for carrying the object to be measured;

[0009] A rotating shaft connected between the transparent carrier and the first wall surface so that the transparent carrier rotates relative to the light box body;

[0010] The variable light source lamp group is arranged on at least one of the second wall surfaces, and the illumination range of the variable light source lamp group at least partially covers the transparent carrier plate.

[0011] In some embodiments, the maximum projection area of ​​the transparent carrier toward the bottom wall is less than or equal to the maximum projection area of ​​the opening toward the bottom wall.

[0012] In some embodiments, the light source colors of the variable light source lamp group include at least: white light, yellow light and green light.

[0013] In some embodiments, the illuminance of the variable light source lamp group ranges from 1200 Lux to 50000 Lux.

[0014] In some embodiments, the axis of the rotating shaft is parallel to the plane where the transparent carrier plate is located; the two first walls arranged opposite to each other are both rotatably connected with the rotating shaft, and the rotating shafts on both sides are coaxially arranged;

[0015] The rotation axis of the transparent carrier is perpendicular to the first wall surface and parallel to the second wall surface.

[0016] In some embodiments, the range of the rotation angle of the transparent carrier relative to the horizontal plane is A, wherein A satisfies 30°≤A≤60°.

[0017] In some embodiments, the inspection light box fixture further includes:

[0018] The arc-shaped guide rail is arranged inside the light box body, and the rotation axis of the arc-shaped guide rail is parallel to the rotation axis of the rotating shaft;

[0019] The follow-up lamp group is arranged on the side of the arc-shaped guide rail facing the opening.

[0020] In some embodiments, the inspection light box fixture further includes: a driving wheel, which abuts against a side of the arc-shaped guide rail facing away from the opening portion, and the driving wheel rotates to drive the arc-shaped guide rail to swing around the axis.

[0024] 1. The inspection light box fixture provided in the embodiment of the present application forms an opening at the top of the light box body, and a transparent carrier is arranged in the opening so that the transparent carrier is rotated relative to the light box body. By arranging a variable light source lamp group on at least one of the second wall surfaces, the illumination range of the variable light source lamp group at least partially covers the transparent carrier. Therefore, when performing appearance inspection, the object to be tested can be continuously illuminated at multiple angles, which facilitates the identification of appearance defects such as edge light transmission, pinhole light leakage, sawtooth, and tooth defects. In particular, for glass products with IR holes, multi-angle illumination can be used to identify poor appearance in the IR hole area, thereby improving detection accuracy and reducing the outflow of defective products.

[0025] 2. By making the maximum projection area of ​​the transparent carrier toward the bottom wall smaller than or equal to the maximum projection area of ​​the opening toward the bottom wall, the transparent carrier will not be interfered by the side wall of the light box body when it rotates relative to the opening, thereby ensuring the free rotation of the transparent carrier and reducing the gap between the transparent carrier and the opening to reduce the entry of dust and other dirt.

[0026] 3. By setting the variable light source group to have adjustable illumination, different light source colors and illumination can be adjusted according to customer requirements to meet inspection conditions. It is suitable for IR process inspection of cover products and printing edge leakage, needle leakage, tooth missing and other defective items to achieve effective identification. In specific production processes, it can be used for first piece inspection, process inspection, and finished product IR inspection.

[0027] 4. By arranging an arc guide rail inside the light box body and arranging a follow-up light group on the side of the arc guide rail facing the opening, multi-angle illumination of the object to be measured on the transparent carrier can be achieved during the movement of the arc guide rail. By increasing the illumination inside the light box body, omission of the detection position can be avoided and the detection accuracy can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] Combine the following Figures 1 to 4 , describing an embodiment of the present application.

[0043] According to an embodiment of the present application, a light box inspection jig is provided, comprising:

[0044] The light box body 1 is constructed as a box structure, and includes a bottom wall 13 and a side wall surrounding the bottom wall 13; two oppositely disposed first walls 11 and two oppositely disposed second walls 12 are connected end to end to enclose and form the side wall; an opening 14 is formed at the top of the light box body 1;

[0045] A transparent carrier plate 3 is disposed in the opening portion 14, and the transparent carrier plate 3 is suitable for carrying the object to be measured;

[0046] The rotating shaft 2 is connected between the transparent carrier 3 and the first wall 11 so that the transparent carrier 3 can rotate relative to the light box body 1;

[0047] The variable light source lamp set 4 is disposed on at least one of the second wall surfaces 12 , and the illumination range of the variable light source lamp set 4 at least partially covers the transparent carrier plate 3 .

[0048] In this embodiment, by providing side walls around the bottom wall 13 of the light box body 1 , the light box body 1 is configured as a groove-shaped box structure, so as to form a receiving cavity inside the light box body 1 .

[0049] Specifically, the side wall can be formed by connecting a plurality of walls end to end. In this embodiment, the side wall is formed by connecting two oppositely disposed first walls 11 and two oppositely disposed second walls 12 end to end. As a variation, the side wall can also be formed by connecting three, five, six or even more walls end to end.

[0050] The wall surface constituting the side wall can be in a planar form or in a curved form.

[0051] An opening 14 is formed at the top of the light box body 1. A transparent carrier 3 is arranged at the opening 14 and is allowed to rotate relative to the light box body 1. Thus, after the object to be measured is placed on the transparent carrier 3, the object to be measured can rotate along with the transparent carrier 3.

[0052] Since the transparent carrier 3 is made of transparent material, when the object to be measured rotates with the transparent carrier 3, the light irradiated by the variable light source lamp group 4 can pass through the transparent carrier 3 to irradiate the object to be measured, ensuring that the light can cover the object to be measured.

[0053] The transparent carrier 3 is rotatably connected to the first wall 11 via a rotating shaft 2, and the variable light source lamp group 4 is arranged on at least one of the second walls 12, so that when the transparent carrier 3 rotates, the variable light source lamp group 4 can gradually change the irradiation angle of the transparent carrier 3, thereby facilitating the inspection of poor appearance.

[0054] The inspection light box fixture provided in the embodiment of the present application forms an opening 14 on the top of the light box body 1, and sets a transparent carrier 3 in the opening 14 so that the transparent carrier 3 can rotate relative to the light box body 1. By setting a variable light source lamp group 4 on at least one of the second wall surfaces 12, the illumination range of the variable light source lamp group 4 at least partially covers the transparent carrier 3. Therefore, when performing appearance inspection, the object under test can be continuously illuminated at multiple angles, which facilitates the identification of appearance defects such as edge light transmission, pinhole light leakage, serrations, and tooth defects. In particular, for glass products with IR holes, multi-angle illumination can be used to identify poor appearance in the IR hole area, thereby improving detection accuracy and reducing the outflow of defective products.

[0055] In some embodiments, in combination Figure 1 As shown, the maximum projection area of ​​the transparent carrier 3 toward the bottom wall 13 is smaller than or equal to the maximum projection area of ​​the opening 14 toward the bottom wall 13 .

[0056] By making the maximum projection area of ​​the transparent carrier 3 toward the bottom wall 13 less than or equal to the maximum projection area of ​​the opening 14 toward the bottom wall 13, the transparent carrier 3 will not be interfered by the side wall of the light box body 1 when it rotates relative to the opening 14, thereby ensuring the free rotation of the transparent carrier 3 and reducing the gap between the transparent carrier 3 and the opening 14 to reduce the entry of dust and other dirt.

[0057] In some embodiments, the light source colors of the variable light source lamp set 4 at least include: white light, yellow light and green light.

[0058] Specifically, the illumination conditions of different bands can be adjusted by adjusting the switch to meet actual illumination needs.

[0059] In some embodiments, there are multiple variable light source lamp groups 4, so as to illuminate from multiple positions and multiple angles to meet the detection requirements.

[0060] In some embodiments, the illuminance of the variable light source lamp group 4 ranges from 1200 Lux to 50000 Lux.

[0061] By setting the variable light source lamp group 4 to have adjustable illumination, different light source colors and illumination can be adjusted according to customer requirements to meet inspection conditions. It is suitable for IR process inspection of cover products and printing edge leakage, needle leakage, tooth missing and other defective items to achieve effective identification. In specific production processes, it can be used for first piece inspection, process inspection, and finished product IR inspection.

[0062] In some embodiments, in combination Figure 1 As shown, the axis of the rotating shaft 2 is parallel to the plane where the transparent carrier 3 is located; the two first walls 11 arranged opposite to each other are both rotatably connected with the rotating shaft 2, and the rotating shafts 2 on both sides are coaxially arranged;

[0063] The rotation axis of the transparent carrier plate 3 is perpendicular to the first wall surface 11 and parallel to the second wall surface 12 .

[0064] In some embodiments, the range of the rotation angle of the transparent carrier 3 relative to the horizontal plane is A, wherein A satisfies 30°≤A≤60°.

[0065] In some embodiments, in combination Figure 2 As shown, the inspection light box fixture also includes:

[0066] The arc guide rail 5 is arranged inside the light box body 1, and the rotation axis of the arc guide rail 5 is parallel to the rotation axis of the rotating shaft 2;

[0067] The follow-up lamp assembly 51 is disposed on a side of the arc-shaped guide rail 5 facing the opening 14 .

[0068] By arranging an arc guide rail 5 inside the light box body 1 and arranging a follow-up light group 51 on the side of the arc guide rail 5 facing the opening 14, multi-angle illumination of the object to be measured on the transparent carrier plate 3 can be achieved during the movement of the arc guide rail 5. By increasing the illumination inside the light box body 1, omission of the detection position can be avoided and the detection accuracy can be improved.

[0069] In some embodiments, the follow-up light group 51 corresponds to the IR hole position of the object to be detected, so that the IR hole position can be focused on.

[0070] As a variation, the arc-shaped guide rail 5 can perform translational movement in a direction parallel to the rotation axis to accommodate IR holes at different positions.

[0071] It should be noted that the arrangement position of the arc guide rail 5 will not interfere with the rotation of the transparent carrier plate 3 .

[0072] In some embodiments, in combination Figure 2 As shown, the inspection light box fixture further includes: a driving wheel 6, which abuts against a side of the arc-shaped guide rail 5 facing away from the opening portion 14, and the driving wheel 6 rotates to drive the arc-shaped guide rail 5 to swing around the axis.

[0073] The arc guide rail 5 is driven by a driving wheel 6. Specifically, the driving wheel 6 may be a gear. A rack is provided on the side of the arc guide rail 5 facing away from the opening 14. The movement of the arc guide rail 5 can be achieved through the meshing of the gear and the rack.

[0074] In some embodiments, in combination Figure 2 As shown, the inspection light box fixture also includes: a power unit 7, which drives the driving wheel 6 to rotate via the transmission shaft 8.

[0075] The power unit 7 may specifically be a motor.

[0076] In some embodiments, the light source colors of the follow-up light group 51 include at least: white light, yellow light and green light; and the illuminance of the follow-up light group 51 ranges from 1200 Lux to 50000 Lux.

[0077] By setting the variable light source lamp group 4 to have adjustable illumination, different light source colors and illumination can be adjusted according to customer requirements to meet inspection conditions. It is suitable for IR process inspection of cover products and printing edge leakage, needle leakage, tooth missing and other defective items to achieve effective identification. In specific production processes, it can be used for first piece inspection, process inspection, and finished product IR inspection.
