[0002] Quality inspection: refers to the activities of checking and verifying whether the quality of products or services complies with relevant regulations. It is divided into air quality inspection, engineering quality inspection, product quality inspection, environmental quality inspection, etc. Visual quality is a higher-level concept than vision. Its inspection indicators include visual acuity measurement, objective visual quality evaluation, contrast sensitivity inspection and subjective feelings, etc. Visual quality can be used to characterize the effectiveness of the entire visual system of the human eye. Inspection usually refers to the inspection of surface defects of objects. Surface defect inspection uses advanced machine vision inspection technology to detect spots, pits, scratches, color differences, defects and other defects on the surface of the workpiece.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 In this embodiment, a visual quality inspection device includes a fixed base 1, and a rotating fixing mechanism is arranged on the top of the fixed base 1.

[0022] In this embodiment, the rotating fixing mechanism includes a rotating motor 2 fixedly mounted on the top of a fixed base 1, a workbench 3 is fixedly mounted on the output shaft of the rotating motor 2, two supporting shafts 4 are fixedly mounted on the bottom of the workbench 3, and a pulley 5 slidably connected to the fixed base 1 is fixedly mounted on the bottom of the supporting shaft 4.

[0023] Among them, a circle of sliding grooves is opened on the top of the fixed base 1, and the pulley 5 is slidingly connected to the fixed base 1 through the sliding groove, which helps the pulley 5 to slide and move on the inner side of the fixed base 1. A reflector 6 is fixedly installed on the inner side of the workbench 3. The reflector 6 is in the shape of an arc and fits the inner side of the workbench 3, which is convenient for increasing the brightness of observation during visual observation.

[0024] In this embodiment, the left and right inner walls of the workbench 3 are threadedly connected with adjusting screws 7, and threaded holes are opened on the left and right sides of the workbench 3. The adjusting screws 7 are threadedly connected to the workbench 3 through the threaded holes, which helps the adjusting screws 7 to move inside the workbench 3. A clamping plate 8 is fixedly installed on one side of the adjusting screw 7, and an installation box 9 is fixedly installed on the front side of the fixed base 1, and an adjusting lifting mechanism is arranged inside the installation box 9.

[0025] Among them, the adjusting lifting mechanism includes a stepper motor 10 fixedly installed inside the installation box 9, the output shaft of the stepper motor 10 is rotatably connected to a reciprocating screw 11 rotatably connected to the installation box 9, the outer side of the reciprocating screw 11 is threadedly connected to a thread block 12, and a thread groove is provided inside the thread block 12. The thread block 12 is threadedly connected to the reciprocating screw 11 through the thread groove, which helps the thread block 12 to move on the outside of the reciprocating screw 11.

[0026] In this embodiment, a support rod 13 is fixedly installed on one side of the threaded block 12, and a limiting groove is provided on one side of the mounting box 9. The support rod 13 is slidably connected to the mounting box 9 through the limiting groove, which helps to limit the support rod 13 and the threaded block 12. A mirror frame 14 is fixedly installed on one side of the support rod 13, and a magnifying glass 15 is fixedly installed inside the mirror frame 14.

[0027] It should be noted that the inspection equipment based on visual quality can clamp and fix the workpiece to be inspected inside the workbench 3 by means of the rotating fixing mechanism, using the adjusting screw 7 and the clamping plate 8, so that it is convenient to clamp and fix workpieces of different sizes, and the magnifying glass 15 can be used to observe the surface condition of the workpiece. By using the stepping motor 10 and the reciprocating screw 11, the mirror frame 14 and the magnifying glass 15 can be driven to move up and down, so that the magnifying glass 15 can be driven to move closer to or away from the workpiece, which helps to observe the workpiece more conveniently.

[0028] The working principle of the above embodiment is:

[0029] When using the visual quality inspection device, the device to be inspected is first placed inside the workbench 3, and then the adjusting screw 7 is rotated. The adjusting screw 7 moves inside the workbench 3 and moves toward the inside of the workbench 3. The movement of the adjusting screw 7 drives the clamping plate 8 to move until the two clamping plates 8 clamp and fix the device to be inspected. Then, the device to be inspected inside the workbench 3 can be observed through the magnifying glass 15 to judge the defects such as spots, pits, scratches, color difference, and defects on the surface of the workpiece. At the same time, the stepping motor 10 can be started, and the stepping motor 10 drives the reciprocating screw 11 to rotate. The threaded block 12 on the outer side of the reciprocating screw 11 is on the support rod 1 3, the threaded block 12 moves downward to drive the support rod 13 and the mirror frame 14 to move downward, thereby driving the magnifying glass 15 to move downward and close to the workpiece to be inspected, so as to facilitate a closer observation of the workpiece, which is suitable for equipment workpieces of different sizes and convenient for adjusting the height of the magnifying glass 15. During the inspection process, the rotating motor 2 can also be started, and the rotating motor 2 drives the workbench 3 to rotate. The workbench 3 rotates smoothly under the support of the pulley 5 and the support shaft 4 at the bottom, which is convenient for driving the workpiece inside the workbench 3 to rotate, and different areas and no questions of the workpiece can be observed through the magnifying glass 15, which greatly improves the practicability of the device.
