[0022] Furthermore, the main light fixing plate 3 has a first tentacle portion, and the main light focusing lens 6 is located on the first tentacle portion.

[0023] In this embodiment, the provision of the first tentacle portion can improve the fixing stability of the main light focusing lens 6, while ensuring that the light source will not be emitted excessively, thereby improving the focusing effect.

The focusing effect is to directly irradiate the detection plane according to the angle, the width of the light band is increased, and it plays the role of side light exposure. The camera is placed directly above the semi-transparent mirror 11, so that the light emitted by the main light source 5 and the side light source 9 coincides with the position of the camera's shooting center line on the detection plane. Because the light source of the side light part is at an angle, the width of the light band irradiated by this light source on the detection plane is wider. Because the focusing effect of the focusing semi-transparent mirror 11 increases the light intensity, the exposure is stronger, the image is clearer, the detection elements of the detected target are more accurate, and overall it is more efficient and accurate.

[0037] In the present invention, by providing higher exposure intensity and light intensity, the image is made clearer; a wider exposure range and scanning range are also provided, so that the equipment detection speed is faster and more complete; at the same time, the focusing effect of the main light focusing lens 6 and the side light focusing lens 10 is more concentrated and effective, which can improve the utilization rate of the light source; and the setting of the main light radiator 4 and the side light radiator 8 is more reasonable and reliable, and the heat dissipation capacity is stronger, which improves the service life of the light source. Finally, based on the above description, the core market competitiveness of machine vision equipment is greatly improved.
