The two first reflectors are symmetrically arranged on both sides of the bottom surface of the top cover. The two second reflectors are symmetrically arranged on the other two sides of the top surface of the top cover. Each of the two first reflectors is provided with a sliding groove. Two light source mounting brackets are slidably connected in the sliding groove for installing lighting sources. The two light source mounting brackets move in the sliding groove towards each other or away from each other. One of the second reflectors is fixedly installed with one of the light source mounting brackets.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] like Figures 1-5 As shown, this utility model provides an adjustable detection light box, including a main frame 1 and a frame 2. The main frame 1 is used to fix the frame 2. The bottom of the frame 2 is open 3. The frame 2 includes a top cover 21, two first reflectors 22 and two second reflectors 23. The top cover 21 is provided with a camera hole 211. The two first reflectors 22 are symmetrically arranged on both sides of the bottom surface of the top cover 21. The two second reflectors 23 are symmetrically arranged on the other two sides of the top surface of the top cover. Each of the two first reflectors 22 is provided with a sliding groove 221. Two light source mounting brackets 222 are slidably connected in the sliding groove 221 for installing the lighting source 223. The two light source mounting brackets 222 move in the sliding groove 221 in a direction that moves closer to or further away from each other. The second reflector 23 is fixedly installed with the light source mounting bracket 222 on the same side.

[0023] Furthermore, such as Figures 1-5 As shown, the camera hole 211 has an elongated shape, and the extending direction of the camera hole 211 is the same as the extending direction of the slide groove 221. Both ends of the light source mounting bracket 222 are slidably engaged with one of the slide grooves 221.

[0024] Specifically, by adjusting the distance between the two light source mounting brackets 222 and the distance between the two second light-emitting plates, the detection space within the frame 2 can be adjusted. When detecting a small object, the two light source mounting brackets 222 move closer together, and the two second reflectors 23 move closer together, reducing the reflective area of ​​the first reflector 22 and minimizing brightness loss due to light reflection on excess reflective area. When detecting a larger object, the two light source mounting brackets 222 move further apart, while the two second reflectors 23 move closer together to adapt to the object being detected. The object may also move as the position of the second reflector 23 changes, making it impossible for the object to be captured by the camera lens. By setting an elongated camera hole 211, the camera lens can move within the range of the camera hole 211. By setting the extension direction of the camera hole 211 to be the same as the extension direction of the slide 221, the camera can be adjusted in the same direction according to the position of the second reflector 23, so that the camera's capture range is adapted to the position of the object to be detected. The camera can also detect the object from multiple angles by moving within the camera hole 211, achieving a variety of detection effects.

[0025] In addition, the sliding engagement of the two ends of the light source mounting bracket 222 with a slide groove 221 can better maintain the perpendicularity of the light source mounting bracket 222 with the first reflector 22 when sliding.

[0026] Furthermore, such as Figures 1-5 As shown, the main frame 1 includes a bottom frame 11, a top frame 12, and columns 13 for connecting the bottom frame 11 and the top frame 12. The bottom frame 11 is used to install the bottom of the first reflector 22 and the second reflector 23, and the top frame 12 is used to install the top of the first reflector 22 and the second reflector 23. The bottom frame 11 includes two first mounting rods 111 and two second mounting rods 112. The first mounting rods 111 are provided with movable grooves 123 corresponding to the sliding grooves 221, for sliding engagement with the light source mounting bracket 222. The first reflector 22 is provided with two sliding grooves 221, which are respectively located at the upper and lower ends of the first reflector 22. The sliding groove 221 located at the lower end of the first reflector 22 is slidably engaged with the light source mounting bracket 222, and the sliding groove 221 located at the upper end of the first reflector 22 is slidably engaged with the second reflector 23. The top frame 12 includes two fixed rods 121 and two movable rods 122. The two fixed rods 121 are symmetrically mounted on the upper ends of the two first reflectors 22, and the movable rods 122 are symmetrically mounted on the upper ends of the two second reflectors 23. Each of the two fixed rods 121 is provided with a movable groove 123 corresponding to the sliding groove 221 located on the upper end of the first reflector 22. The two ends of the movable rod 122 are slidably connected to the movable groove 123 on one of the fixed rods 121.

[0027] Specifically, such as Figures 1-5 As shown, the light source mounting bracket 222 slides within the slide groove 221 to achieve position adjustment. Both ends of the light source mounting bracket 222 are provided with screw holes, which are threaded with fixing bolts. The fixing bolts pass sequentially through the slide groove 221 of the first reflector 22 and the movable groove 123 of the first mounting rod 111, and are threadedly connected to the screw holes on the side of the light source mounting bracket 222. When the light source mounting bracket 222 needs to be fixed in position, the fixing bolts are screwed into the screw holes, clamping the first reflector 22 and the first mounting rod 111 between the head of the fixing bolts and the light source mounting bracket 222, achieving a fixing effect. When the position of the light source mounting bracket 222 is adjusted, the fixing bolts are unscrewed from the screw holes, loosening the connection between the head of the fixing bolts and the light source mounting bracket 222, achieving a convenient tightening / loosening effect.

[0028] Based on the above, such as Figures 1-5 As shown, the first reflector 22 has sliding grooves 221 at its upper and lower ends, and the movable groove 123 on the first mounting rod 111 corresponds to the sliding groove 221 at the lower end of the first reflector 22. Meanwhile, the second reflector 23 has a movable rod 122 mounted on its top, and its bottom is mounted to the light source mounting bracket 222. The movable groove 123 on the fixed rod 121 corresponds to the sliding groove 221 at the upper end of the first reflector 22. When adjusting the position of the second reflector 23, its upper and lower ends can simultaneously correspond to the sliding groove 221 and the movable groove 123, respectively. Regarding the sliding fit, it should be noted that when the second reflector 23 moves, the upper end of the second reflector 23 slides in the corresponding movable groove 123 and sliding groove 221 via the movable rod 122, and the lower end of the second reflector 23 slides in the corresponding movable groove 123 and sliding groove 221 via the light source mounting bracket 222. The movable rod 122 is provided with screw holes and fixing bolts. The way the movable rod 122 slides in the movable groove 123 and sliding groove 221 is the same as the way the light source mounting bracket 222 slides in the movable groove 123 and sliding groove 221, which will not be described again here.

[0029] Furthermore, such as Figures 1-5 As shown, the two movable rods 122 are provided with mounting grooves 124 for mounting the lighting source 223.

[0030] Specifically, when detecting a small object, the two light source mounting brackets 222 move closer to each other, and the two second reflectors 23 move closer to each other, reducing the reflective area of ​​the first reflector 22 and reducing the brightness loss of light reflected on the excess reflective area, thus improving the lighting effect. When detecting a larger object, the two light source mounting brackets 222 move further apart, and the two second reflectors 23 move closer to each other to adapt to the object. However, when detecting a larger object, the reflective area of ​​the first reflector 22 becomes larger, and the light may lose brightness due to reflection, resulting in insufficient brightness inside the frame 2. The brightness loss can be compensated by simultaneously installing the lighting source 223 on the mounting slot 124 on the movable rod 122 to supplement the light of the object.

[0031] Furthermore, such as Figures 1-5 As shown, the two ends of the second mounting rod 112 are respectively connected to a column 13, and a movable position 113 is formed between the second mounting rod 112 and the second reflector 23.

[0032] Specifically, by forming a movable position 113 between the second mounting rod 112 and the second reflector 23, it is possible to facilitate manual gripping of the second mounting rod 112 and transfer of the adjustable detection light box, thereby achieving flexible position changes.

[0033] The following is a detailed explanation of the working principle of this utility model; In use, the object to be detected is placed on the working surface, and the adjustable detection light box is inverted on the working surface, with the object inside the adjustable detection light box. The illumination source 223 illuminates all surfaces of the object within the frame 2. The camera detects the object within the frame 2 through the camera hole 211. The distance between the light source mounting brackets 222 can be adjusted according to the size of the object, thereby adjusting the distance between the illumination sources 223. During adjustment, the light source mounting brackets 222 are slid closer to or further away from each other within the slide groove 221, thereby adjusting the reflective area of ​​the first reflector 22. When detecting a small object, the two light source mounting brackets 222 move closer to each other, and the two second reflectors 23 move closer to each other, reducing the reflective area of ​​the first reflector 22 and reducing the brightness loss of light reflected on the excess reflective area, thus improving the illumination effect. When detecting a large object, the two light source mounting brackets 222 move further away from each other, and the two second reflectors 23 move closer to each other to adapt to the object and improve the applicability.

This narrative style of the specification is merely for clarity.
