[0045] Please refer to Figures 1 to 4 This utility model provides a visual inspection device, including a coaxial light source 1 and at least two sets of bar light components 2.

[0046] Among them, the bar light component 2 is installed on the light-emitting side of the coaxial light source 1, and the bar light component 2 is fixedly connected to the coaxial light source 1; the bar light component 2 includes two bar light sources 21 arranged at intervals opposite to each other, and a product detection interval 22 is formed between the two bar light sources 21. The light emitted by the coaxial light source 1 can be directed to the top of the product 100 through the product detection interval 22, and the bar light sources 21 in the same group emit light into the corresponding product detection interval 22, thereby illuminating the opposite sides of the product 100.

[0047] In this embodiment, only one coaxial light source 1 and multiple sets of bar light components 2 are needed to simultaneously illuminate multiple products 100, which is beneficial to improving the detection efficiency of product 100 and better detecting the edge surface condition of product 100. The coaxial light source 1 can illuminate the top of product 100, and each set of bar light components 2 can illuminate the opposite two sides of product 100, which is significantly beneficial to improving the detection accuracy of the edges.

[0048] Optionally, the strip light source 21 includes a base plate 211, a first lamp plate 212, a frame body 213, and a diffuser plate 214. The base plate 211, the frame body 213, and the diffuser plate 214 enclose a sealed space for mounting the first lamp plate 212. The first lamp plate 212 is installed in the sealed space and emits light towards the diffuser plate 214. The diffuser plates 214 of the strip light sources 21 in the same group are parallel to each other and face each other, so that the illumination effect on opposite sides of the product 100 is basically the same, and it is beneficial to improve the ease of transfer of the product 100. The product 100 can flow into the set detection position along the product detection interval 22, and can also flow out along the product detection interval 22.

[0049] Optionally, the frame body 213 extends to a mounting protrusion 2001, which is provided with a mounting through hole; a threaded connector passes through the mounting through hole and is threadedly connected to the coaxial light source 1 to fix the strip light source 21 on the coaxial light source 1.

[0050] Specifically, the bar light source 21 is detachably connected to the coaxial light source 1. Once the bar light source 21 is damaged, it can be removed and replaced with a new bar light source 21 in a timely manner.

[0051] Optionally, each set of bar light components 2 is electrically connected to a control component so that the opening and closing of the bar light components 2 can be controlled independently, thereby enabling the appropriate number of bar light components 2 to be opened according to actual needs, thus enabling the appropriate number of products 100 to be opened.

[0052] Optionally, in two adjacent sets of strip light components 2, one strip light source 21 is arranged back-to-back with another strip light source 21 of the other type. The backs of the two back-to-back strip light sources 21 abut against each other, and a heat dissipation hole is formed at the abutment position. In this embodiment, vertical grooves are provided on the backs of the two back-to-back strip light sources. The two back-to-back strip light sources fit together, and the grooves form heat dissipation holes, which can effectively improve heat dissipation efficiency.

[0053] Optionally, the coaxial light source 1 includes a support housing 101, a beam splitter 102 installed in the support housing 101, and a second lamp plate 103 installed on one side of the beam splitter 102; the beam splitter 102 is tilted at 45°, and the second lamp plate 103 is vertically arranged to emit light toward the beam splitter 102.

[0054] Specifically, in this embodiment, the normal operation of the second lamp board 103 will not block the light from the camera 3.

[0055] Optionally, a detection hole 104 is provided on the top of the support housing 101; and a light-emitting window 105 is provided on the bottom of the support housing 101 corresponding to the beam splitter 102.

[0056] Optionally, a diffuser plate 106 is installed between the beam splitter 102 and the second lamp plate 103; an electrochromic film is provided on the surface of the diffuser plate 106 away from the second lamp plate 103. Specifically, the diffuser plate 106, in conjunction with the electrochromic film, can better control the light output effect.

[0057] Optionally, the visual inspection device also includes a camera 3, which is mounted on the top side of the inspection hole 104; all cameras 3 share the inspection hole 104.

[0058] Optionally, in the same group of bar light components 2, one bar light source 21 emits light of the first color, and the other bar light source 21 emits light of the second color, so that the detection effect of products 100 of different colors on both sides is better.

[0059] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
