Technical Field
[0001] The utility model relates to the technical field of laser cutting equipment, in particular to a light source adjustment device for a visual inspection system. Background Art
[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the material strip, causing the material of the material strip to reach the melting point or boiling point. As the relative position of the laser beam and the material strip moves, a slit is eventually formed on the material strip, thereby achieving the purpose of cutting.
[0003] The main problem in cutting flexible strips with a laser cutting machine is that different products have different production process requirements, resulting in certain differences in the cutting position of the strips. If only relying on the upper light source at the laser, it is impossible to assist the visual system to complete the precise positioning of the cutting position, which is prone to cutting errors.
[0004] Therefore, there is a need for a light source adjustment device for a visual inspection system that can solve the above problems. Utility Model Content
[0005] The utility model proposes a light source adjustment device for a visual inspection system, which adds an adjustable lower light source that matches the upper light source, thereby achieving accurate positioning of the cutting site by the visual system and solving the problem of positioning errors of the visual system caused by insufficient light source.

[0008] Each of the light source brackets includes a bottom shaft, each of the bottom shafts extends along the width direction of the waste suction box, each of the bottom shafts is fixedly installed on the bottom wall of the waste suction box, one end of each of the bottom shafts is hinged with a first connecting rod, the end of the first connecting rod away from the bottom shaft is hinged with a second connecting rod, the end of the second connecting rod away from the first connecting rod is hinged with a top shaft, each of the lower light sources is fixedly installed on the corresponding top shaft, and a fastening screw is installed at each hinge between the bottom shaft and the first connecting rod, the hinge between the first connecting rod and the second connecting rod, and the hinge between the second connecting rod and the top shaft.
[0009] As a preferred technical solution, the waste suction box is open, a top plate is provided on the top of the waste suction box, and the leakage port is penetrated through the top plate.
[0010] As a preferred technical solution, at least two pairs of long waist holes are provided on the top plate, each of the long waist holes extends along the length direction of the waste suction box, and a precision bolt is provided between each of the long waist holes and the waste suction box.
[0011] As a preferred technical solution, a pair of slide rails are fixed to the top of the waste suction box, each of the slide rails extends along the length direction of the waste suction box, and the top plate is slidably installed on the top of the waste suction box through the slide rails.
[0012] As a preferred technical solution, two oppositely arranged first planes are provided on the outer circumferential surface of the bottom shaft, one of the first planes is pressed against the bottom wall of the waste suction box, and each of the bottom shafts is fixed to the bottom wall of the waste suction box by a plurality of locking bolts.
[0013] As a preferred technical solution, two oppositely arranged second planes are provided on the outer circumference of the top shaft, and one of the second planes is pressed tightly against the bottom of the lower light source.
[0014] By adopting the above technical solution, the beneficial effects of the utility model are as follows:
[0015] Since the light source adjustment device of the visual inspection system includes a waste suction box, a material leakage port, a lower light source and a light source bracket, in the utility model, the irradiation position and irradiation angle of the lower light source are adjusted by the light source bracket so that the lower light source irradiates the corresponding point and cooperates with the upper light source on the laser to assist the visual system in accurately locating the cutting position of the material strip, thereby solving the problem of errors in the positioning of the visual system caused by insufficient light.
[0016] Since the light source brackets include a bottom shaft, a first connecting rod, a second connecting rod and a top shaft that are hinged in sequence, in the utility model, the staff adjusts the position and the irradiation angle of the lower light source by rotating the first connecting rod and the second connecting rod, so that the utility model is suitable for cutting production work of different products, thereby improving the applicability of the utility model; a fastening screw is installed at the hinges of the bottom shaft and the first connecting rod, the first connecting rod and the second connecting rod, and the second connecting rod and the top shaft.

In the utility model, the staff adjusts the irradiation position and irradiation angle of the lower light source 3 by adjusting the light source bracket 4, so that the lower light source 3 irradiates the corresponding point; at the same time, the lower light source 3 irradiating upward is used in conjunction with the upper light source irradiating downward on the laser, so as to assist the visual system in accurately locating the cutting position of the material strip, thereby solving the problem of error in the positioning of the visual system caused by insufficient light.
[0027] Among them, each light source bracket 4 includes a bottom shaft 5, each bottom shaft 5 extends along the width direction of the waste suction box 1, each bottom shaft 5 is fixedly installed on the bottom wall of the waste suction box 1, one end of each bottom shaft 5 is hinged with a first connecting rod 6, the end of the first connecting rod 6 away from the bottom shaft 5 is hinged with a second connecting rod 7, the end of the second connecting rod 7 away from the first connecting rod 6 is hinged with a top shaft 8, each lower light source 3 is fixedly installed on the corresponding top shaft 8, and a fastening screw 9 is installed at the hinge between each bottom shaft 5 and the first connecting rod 6, the hinge between the first connecting rod 6 and the second connecting rod 7, and the hinge between the second connecting rod 7 and the top shaft 8.
[0028] In the utility model, when the lower light source 3 needs to be adjusted, the fastening screws 9 are loosened outwards to enable relative rotation between the bottom shaft 5, the first connecting rod 6, the second connecting rod 7 and the top shaft 8. The staff rotates the first connecting rod 6 and the second connecting rod 7 to adjust the lower light source 3 to the corresponding irradiation position and irradiation angle. The adjustable lower light source 3 structure makes the utility model suitable for cutting production work of different products, thereby improving the applicability of the utility model.
