[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides the following technical solution:

[0027] Example 1 addresses the problem that existing auxiliary lighting equipment lacks a protective storage mechanism when it stops providing illumination, leading to damage from external pressure and impacts and reducing the usability of machine vision systems. This example discloses a system consisting of a support column 1 and a storage frame 2. The storage frame 2 is installed on the top outer side of the support column 1 and has a hollow interior. An auxiliary plate 3 is rotatably mounted inside the storage frame 2, and a mirror 7, smaller than the volume of the auxiliary plate 3, is located on the rear side of the auxiliary plate 3. A limiting block 4 is slidably installed through a slot on the inner right side of the auxiliary plate 3, with its outer end extending to the outer right side of the storage frame 2. The right side of the limiting block 4 is inclined, and its left end is T-shaped. A protective pad 9 is fitted to the inner rear wall of the storage frame 2, with the mirror 7 corresponding to the front side of the protective pad 9. A limiting groove 8 is provided at the right end of the auxiliary plate 3, and a limiting block 4 is slidably connected through the inside of the limiting groove 8, and the limiting block 4 and the limiting groove 8 form a snap-fit ​​connection.

[0028] like Figures 1-6 As shown, after the auxiliary lighting equipment stops providing auxiliary lighting, the auxiliary plate 3 is manually pushed to rotate and store the mirror 7 via the rotating shaft 10. This allows the auxiliary plate 3 to rotate and store the mirror 7 inside the storage frame 2, thus preventing damage to the mirror 7 caused by external pressure and collisions. This not only extends the lifespan of the mirror 7 but also improves the practicality of the machine vision system. After the auxiliary plate 3 is rotated and stored inside the storage frame 2, the two compression springs 6 automatically push the top plate 5 with their own elasticity, causing the limiting block 4 to pop out through the limiting groove 8 to the right side of the storage frame 2. This limits and fixes the rotated auxiliary plate 3. After the mirror 7 is stored inside the storage frame 2, the protective pad 9 on the inner rear wall of the storage frame 2 provides cushioning and protection for the stored mirror 7, further enhancing its practicality.

[0029] The embodiment two is different from the embodiment one, the auxiliary lighting device used can be assisted to pop up, and the use of the auxiliary lighting is facilitated in the later period, and the embodiment two discloses:

[0030] The right side of the auxiliary plate 3 is internally slotted to be provided with two extrusion springs 6, the two extrusion springs 6 are of the same structure, and the outer ends of the two extrusion springs 6 are connected with the top plate 5, and the top plate 5 is slidingly installed in the right side of the auxiliary plate 3. The left side of the storage frame 2 is rotatably provided with a rotating shaft 10, and the outer side of the rotating shaft 10 is connected with the auxiliary plate 3. The outer side of the rotating shaft 10 is wound with a torsion spring 11, and the outer side of the torsion spring 11 is connected with the auxiliary plate 3.

[0031] As shown in Figures 1-3 When the auxiliary lighting device is needed to be used to cooperate with the machine vision system to detect, the limiting block 4 is manually pressed to move inwards, so that the limiting block 4 is separated from the limiting groove 8, the auxiliary plate 3 can be conveniently rotated and reset, at this time the torsion spring 11 can reset the position of the auxiliary plate 3 after rotation by the elastic force of the torsion spring 11, at this time the auxiliary plate 3 can drive the mirror 7 arranged on the rear side of the auxiliary plate 3 to assist the machine vision system to detect, and the practicability is better.
