The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.

The embodiment of the utility model provides a detection light source which can be beneficial to improving the detection precision of a product to be detected with stronger light reflection capability.

Referring to fig. 1 to 5, the inspection light source includes a support plate 1 and a light emitting assembly 2 mounted on the support plate 1. The support plate 1 has a function of supporting the light emitting assembly 2.

Wherein the supporting plate 1 has a first plate surface 11 facing the product to be inspected and a second plate surface 12 opposite to the first plate surface 11; the light-emitting component 2 is arranged on the second plate surface 12, and the light-emitting component 2 at least partially extends out of the side of the supporting plate 1 to illuminate the product to be detected; the first plate surface 11 is provided with a matting layer.

The matting layer is a light-absorbing coating, a paint layer or a sheet material, such as a black coating, a black paint layer or a black sheet material, etc.

In addition, the light emitting component 2 is disposed on the second plate 12, and the partial volume of the light emitting component 2 is blocked by the supporting plate 1, so that the probability that the light reflected by the light emitting component 2 is emitted to the surface of the detected product is lower, which is also beneficial to improving the detection precision.

Except for the portion of the housing 21 extending out of the support plate 1, the rest of the housing 21 is blocked by the support plate 1 and cannot reflect light directly onto the product to be inspected.

The detection light source further comprises a threaded connector 23 detachably connected with the shell 21, and the sliding groove 101 penetrates through the support plate 1; the screw portion of the screw coupling 23 is coupled to the housing 21 through the sliding groove 101 so that the housing 21 is fixedly coupled to the support plate 1.

As shown in fig. 4, the light emitting component 2 can be adjusted to move up or down, so as to adjust the size of the light emitting window 201, thereby meeting the detection requirements of products to be detected with different sizes, such as longer battery cell tabs or shorter battery cell tabs. After the position of the light emitting assembly 2 is adjusted, the threaded connection 23 is screwed again.

In a specific embodiment, the direction of the light-emitting window 201 is perpendicular to the first plate surface 11, so that the light emitted from the light-emitting window 201 is easier to align with the product to be detected.

Wherein, be provided with the reflectance coating, can be favorable to reducing the loss of light. The diffusion film 243 can diffuse the light to make the light emitted from the light-emitting window 201, so that the light in the light-emitting window 201 is more uniform.

Alternatively, as shown in fig. 4, the light emitting member 22 is disposed on one side of the light guiding assembly 24; the light emitted from the light emitting member 22 enters the light guide plate 241 from between the diffusion film 243 and the reflection film 242.

Preferably, the inner shell wall of the housing 21 is provided with a reflective coating.

Optionally, the matting layer is a matting paint layer, and the matting layer is fully coated on the first board surface 11.

Optionally, the housing 21 has a stop step 202; when the limit step 202 abuts against one side edge of the support plate 1, the area of the light emitting window 201 is minimum. The limiting step 202 can effectively prevent the light emergent window 201 from being too small, and ensures the intensity of emergent light.

Optionally, the detection light source further comprises a power line 4; the casing 21 is further formed with a wiring groove 203, the power cord 4 is disposed in the wiring groove 203 in a penetrating manner, and one end of the power cord 4 is connected with the light emitting element 22.
