Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology, specifically to an auxiliary driving mechanism for visual inspection. Background Technology

[0002] Visual inspection is a method of measurement and judgment using machine vision technology. It involves converting the target to be inspected into image signals using machine vision products, then processing these signals through a dedicated image processing system to extract the target's features, and controlling the actions of on-site equipment based on the judgment results. Visual inspection is widely used in production, assembly, and packaging processes to detect defects and prevent defective products from being delivered to consumers.

[0003] Visual inspection technology integrates electronics, photoelectric detection, image processing, and computer technology. It acquires image signals of targets through machine vision products, then uses image processing algorithms to extract feature information from the images, and performs operations such as locating, identifying, and classifying surface defects, as well as statistical analysis, storage, and retrieval.

[0004] The auxiliary drive mechanism used in visual inspection is relatively complex in structure and has a high manufacturing cost, which is not conducive to the widespread use of the device structure and also leads to high maintenance costs.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an auxiliary driving mechanism for visual inspection. Utility Model Content

The first drive assembly 1 includes a fixed base 101, a first guide rail 102, a first servo motor 103, and a first lead screw 104. The top center of the fixed base 101 is horizontally mounted... The first guide rail 102 is installed, and a first servo motor 103 is installed at one top end of the fixed base 101. The power output end of the first servo motor 103 is horizontally mounted with a first lead screw 104 via a coupling. The first guide rail 102 is installed on the top of the fixed base 101 with a recessed structure, and the first lead screw 104 is horizontally mounted directly above the first guide rail 102. The front and rear ends and the left and right ends of the fixed base 101 are provided with mounting holes for bolt fixing. The first servo motor 103 and the fixed base 101 are fixedly connected to each other. Under the operation of the electric constant force hinge 305, it can provide reverse adjustment mobility within a certain angle range on both sides in the vertical direction. The electric rotating shaft 304 connected to the bottom of the electric constant force hinge 305 can provide horizontal rotation adjustment for the electric constant force hinge 305 and the fixed base 4. At the same time, under the operation of the first drive assembly 1 and the second drive assembly 2, it can also provide horizontal cross axis movement adjustment.

[0025] like Figures 1 to 4 As shown, the second drive assembly 2 includes a moving stage 201, a second guide rail 202, a second servo motor 203, a second lead screw 204, a connecting slider 205, and a support angle plate 206. The second guide rail 202 is horizontally mounted at the top center of the moving stage 201, and the second servo motor 203 is mounted at one top end of the moving stage 201. The power output end of the second servo motor 203 is horizontally mounted to the second lead screw 204 via a coupling. The connecting slider 205 is connected to the bottom center of the moving stage 201, and support angle plates 206 are provided on both sides of the connecting slider 205. The second guide rail 202 is mounted on the top of the moving stage 201 using a recessed structure, and the second lead screw 204 is horizontally mounted directly above the second guide rail 202. The fixed base frame 4 is fixedly connected to the end of the electric constant force hinge 305 away from the electric rotating shaft 304. The connecting slider 205...

One end of the support arm 302 is connected and fixed to the guide module 301 by two sets of connecting angle plates 303 and bolts.

[0026] In summary, as Figures 1 to 4 As shown, the auxiliary drive mechanism for visual inspection is used by first installing the visual inspection equipment to be used on the surface of the fixed base 4. During inspection, the first servo motor 103 at one end of the fixed base 101 drives the first lead screw 104 connected to it to rotate horizontally. This causes the second drive assembly 2 to move horizontally along the surface of the first guide rail 102 and the first lead screw 104 with the assistance of the connecting slider 205 connected by the support angle plate 206 at the bottom of the moving stage 201.

[0027] Meanwhile, the second servo motor 203 at one end of the mobile stage 201 will operate synchronously and drive the second lead screw 204 connected to it to rotate horizontally, so that the third drive assembly 3 and the fixed base frame 4 equipped with the vision inspection device will translate along the surface of the second guide rail 202 and the second lead screw 204 in the horizontal X-axis direction using the guide module 301.

[0028] Meanwhile, the electric rotating shaft 304 and the electric constant force hinge 305 connected to one end of the support arm 302 can respectively provide reverse adjustment activity within a certain angle range on both sides in the vertical direction and rotation adjustment in the horizontal direction, thereby providing sufficient rotation adjustment for the vision inspection device.
