[0026] Please see Figure 1-3 A precision hardware parts appearance inspection device, including an inspection table 1;

[0027] A conveyor belt 2 is horizontally installed in the middle of the upper surface of the testing table 1;

[0028] Pushing cylinders 3 are respectively arranged on the front and rear sides of the middle of the upper end face of the inspection table 1. The telescopic ends of the pushing cylinders 3 are respectively arranged relative to the conveyor belt 2 and are equipped with L-shaped baffles 4. The two baffles 4 are inverted relative to each other. When the pushing cylinders 3 drive the baffles 4 to move inward, the two baffles 4 abut against each other. The middle of the two inner sides of the baffles 4 are respectively provided with first industrial cameras 5.

[0029] A support frame 6 is provided at the upper part of the middle of the testing table 1. A lifting cylinder 7 is provided at the upper part of the support frame 6. The telescopic end of the lifting cylinder 7 is set downward and a rectangular light shield 8 with an opening at the lower end is installed. A second industrial camera 9 is provided at the center of the upper part of the light shield 8.

[0030] During operation, the hardware is placed on the conveyor belt 2 with the end face to be inspected facing upwards. When the conveyor belt 2 moves the hardware to the middle of the inspection table 1, the conveyor belt 2 stops working. The two pusher cylinders 3 drive the baffles 4 to move inwards until the two baffles 4 abut against each other. At the same time, the lifting cylinder 7 drives the light shield 8 to descend, covering the hardware and creating a light-shielding environment. Then, the end face of the hardware to be inspected is photographed by the first industrial camera 5 and the second industrial camera 9. By providing a light-shielding environment, the clarity and completeness of the images are improved, and the accuracy of the inspection is enhanced.

[0031] A further solution: Each of the first industrial cameras 5 and the second industrial camera 9 has a supplementary light 10 electrically connected to one side of each other.

[0032] During the shooting process, the first industrial camera 5 and the second industrial camera 9 take turns shooting the hardware parts individually. During the shooting, adjacent supplementary lights provide illumination, thereby effectively improving the clarity of the inspection.

[0033] A further solution: the baffle 4 and the telescopic end of the pusher cylinder 3 are detachably connected, and the light shield 8 corresponds to the rectangle formed by the two baffles 4 abutting each other and is sleeved on the outside of the baffle 4.

[0034] Different baffles 4 can be replaced according to the size of the hardware components to ensure that the hardware components are covered; the light shield 8 works in conjunction with the baffle 4 to achieve an effective light-blocking shooting environment.

[0035] A further solution: A sliding groove 11 is provided at the lower part of the baffle 4, and the surface of the conveyor belt 2 extends into the sliding groove 11, so that the baffle 4 and the conveyor belt 2 are mutually limited and slidably engaged.

[0036] This can prevent light leakage at the bottom of the baffle 4, thus improving shooting capabilities.

[0037] A further solution: A detection control panel 12 is provided on one side of the detection table 1, which is electrically connected to the first industrial camera 5 and the second industrial camera 9.

[0038] After the first industrial camera 5 and the second industrial camera 9 finish capturing images, they are transmitted to the inspection control panel 12 for comparison and inspection, thereby achieving intelligent inspection and improving inspection efficiency.

[0039] A further solution: Multiple limit blocks 13 are evenly spaced on the surface of the conveyor belt 2.

[0040] When hardware is placed on conveyor belt 2, its position is limited and fixed, which facilitates the control of the start and stop of conveyor belt 2 and the covering of hardware by baffle 4.

[0041] The circuits, electronic components, and control modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0042] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
