Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment technology, specifically a multi-directional three-dimensional motion visual inspection device. Background Technology

[0002] Visual inspection typically involves using machine vision products to transmit images to a dedicated image processing system; machine vision inspection methods can significantly improve production efficiency and the degree of automation in production.

[0003] Patent (CN221631327U) discloses a machine vision inspection device for printed circuit boards, including a device body with an operating table. A conveyor belt is positioned above the operating table, and fixed frames are installed at both ends of the conveyor belt. Each fixed frame has a lower mounting plate and a support leg. An upper mounting plate is positioned above the lower mounting plate. Mounting holes are formed in both the upper and lower mounting plates, and an electric push rod is installed within each mounting hole. A limit plate is installed at the front end of the electric push rod. A mounting frame is connected above the support leg, and a mounting groove is formed within the mounting frame. A lead screw is installed within the mounting groove, and one end of the lead screw is connected to a motor, with a collar fitted onto the lead screw. This device can limit and guide the printed circuit board to be inspected, preventing positional displacement of the circuit board during inspection and affecting subsequent inspections. It also allows for horizontal adjustment of the device's vision inspection structure as needed, increasing the device's practicality and convenience.

[0004] The machine vision inspection device in the aforementioned patent can adjust the movement of the vision acquisition component on the X and Z axes, but the movement on the Y axis mainly relies on the conveying movement of the product under test. This results in the vision inspection device in the device only being able to perform visual inspection on planar products, and being unable to perform accurate visual inspection on products with other shapes.

[0026] The working principle of this utility model:

[0027] Refer to the instruction manual appendix Figures 1-4 This utility model comprises a detection frame 1, a conveyor frame 2, a support ring 101, a support frame 102, a three-dimensional adjustment frame 103, a connecting plate 104, a servo electric cylinder 105, a rack 106, a first gear 107, and a vision camera 108. The conveyor frame 2 is used to transport the product under test, facilitating continuous visual inspection. The detection frame 1 provides overhead support for the visual inspection equipment. The support ring 101 rotates at the bottom inner side of the detection frame 1, and the support frame 102 rotates with the support ring 101. The three-dimensional adjustment frame 103 drives the vision camera 108 on the connecting plate 104 to perform three-dimensional movement in the X, Y, and Z axes. Simultaneously, the three-dimensional adjustment frame 103 can also rotate with the visual camera 108. The support frame 102 rotates, which in turn drives the vision camera 108 to rotate, enabling the vision camera 108 to perform three-dimensional motion in the X, Y, and Z axes while also performing circular motion. The servo electric cylinder on the connecting plate 104 extends and retracts, which drives the rack 106 to reciprocate. During the reciprocating motion of the rack 106, the first gear 107 reciprocates, which in turn drives the vision camera 108 to reciprocate, allowing the tilt angle of the vision camera 108 to be quickly adjusted. This enables the vision camera 108 to perform three-dimensional motion in the X, Y, and Z axes while also performing circular motion and tilt angle adjustment, thereby achieving multi-directional three-dimensional motion-based visual inspection processing of the product under test.

[0028] The servo motor 110 can drive the second gear 111 to rotate, and the rotation of the second gear 111 can drive the ring tooth 109 on the outer wall of the support ring 101 to rotate, which can effectively adjust the rotation of the support ring 101. The auxiliary disk 112 can provide auxiliary shielding for the three-dimensional adjustment frame 103 and the vision camera 108 above the support ring 101, which can play a certain role in dust prevention. The limiting disk can effectively limit and support the support ring 101 on the inner side, which can effectively ensure the safety and stability of the rotation of the support ring 101.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
