Description

Technical Field

[0001] This application relates to the field of appearance inspection technology, and in particular to an appearance inspection device. Background Technology

[0002] Visual inspection is a method for automatically identifying surface defects in products using machine vision technology, primarily applied in industrial manufacturing. This method acquires surface information through image acquisition equipment and combines it with algorithms to analyze defect features such as foreign objects, scratches, and stains. Its core technologies include defect morphology analysis, dynamic threshold processing, and multimodal imaging, enabling detection with an accuracy of 0.037mm. In industries such as automotive, electronics, and food packaging, this technology can perform complex tasks such as catalyst breakage detection, battery size measurement, and bottle cap identification. Compared to traditional visual inspection, it offers advantages such as higher detection efficiency, stronger stability, and adaptability to the needs of automated production lines.

[0003] The current product appearance inspection process requires checking multiple sides sequentially, and the product must be flipped over one by one during the inspection. The manual flipping process is labor-intensive and time-consuming, resulting in low product appearance inspection efficiency and making it difficult to meet market demands.

[0004] Therefore, a visual inspection device is proposed. Utility Model Content

[0020] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0021] This application discloses an appearance inspection device. For example... Figure 1 As shown, a frame 1 is fixedly connected to the top of the base plate 8. An adjustment assembly is set inside the frame 1. The adjustment assembly includes two connecting rods 10, a lead screw 3, a drive block 4, and a first motor 2. The first motor 2 is fixedly connected to the top of the frame 1. The two ends of the two connecting rods 10 are fixedly connected to the inner side of the frame 1 and one side of the base plate 8, respectively. The output end of the first motor 2 passes through the frame 1 and is fixedly connected to one end of the lead screw 3. The other end of the lead screw 3 is rotatably connected to the top of the base plate 8. The first motor 2 can provide power for the lead screw 3 to rotate. The drive block 4 is sleeved and installed outside the two connecting rods 10 and the lead screw 3. The drive block 4 can be moved by rotating the lead screw 3. The drive block 4 is slidably connected to the two connecting rods 10 and threadedly connected to the lead screw 3.

[0022] Please see Figures 1 to 3A crossbar 5 is provided on one side of the adjustment component. A second motor 13 is fixedly connected to one end of the crossbar 5. A rotating shaft 14 is fixedly connected to the output end of the second motor 13. The second motor 13 provides power for the rotation of the rotating shaft 14. A fixing component 9 is provided on one side of the rotating shaft 14. A mounting base 15 is provided on one side of the fixing component 9. The mounting base 15 is rotatably connected to one end of the rotating shaft 14. A limiting disk 6 is fixedly connected to the outside of the crossbar 5. A turntable 21 is installed on the outside of the crossbar 5 and rotatably connected to one side of the limiting disk 6. Two fixing plates 18 are fixedly connected to one side of the turntable 21. A sliding groove 20 is opened on one side of each of the two fixing plates 18. Two sliders 19 are slidably connected inside each of the two sliding grooves 20. A rotating component is provided on the outside of the two sliders 19. The rotation of the turntable 21 facilitates the synchronous rotation of the rotating component. Two diagonal braces 7 are fixedly connected between the drive block 4 and the limiting disk 6 to increase the strength of the connection between the drive block 4 and the limiting disk 6.

[0023] Please see Figures 1 to 4 The rotating assembly includes an electric push rod 16, a moving frame 17, two first inclined plates 11, and two second inclined plates 12. The electric push rod 16 is fixedly connected to one side of the turntable 21. The moving frame 17 is sleeved and fixedly connected to one side of the two sliders 19. The moving frame 17 is driven to move by the electric push rod 16 to achieve stable driving of the sliders 19. The two second inclined plates 12 are fixedly connected to both ends of the mounting base 15. The two ends of the two first inclined plates 11 are rotatably connected to one side of the two second inclined plates 12 and one side of the moving frame 17. The rotation of the first inclined plates 11 drives the second inclined plates 12 to rotate, which can flip the fixed frame 95.

[0024] Please see Figures 1 to 2 The fixing component 9 includes a fixing frame 95, two locking blocks 91, a bidirectional screw 93, a drive handle 92, and two elastic pads 94. The fixing frame 95 is fixedly connected to the mounting base 15. The two ends of the bidirectional screw 93 are rotatably connected inside the fixing frame 95. The two locking blocks 91 are threadedly connected to the outside of the bidirectional screw 93. The relative movement of the locking blocks 91 can be achieved by rotating the bidirectional screw 93. One end of the two locking blocks 91 is embedded and slidably connected to the inside of the fixing frame 95. The two elastic pads 94 are fixedly connected to one side of the two locking blocks 91. The elastic pads 94 provide protection when the workpiece is clamped. The drive handle 92 is located on the outside of the fixing frame 95, and one end of the drive handle 92 passes through the fixing frame 95 and is fixedly connected to one end of the bidirectional screw 93. The drive handle 92 facilitates the rotation of the bidirectional screw 93. The mounting base 15 is fixedly connected to the fixing frame 95.

[0025] The implementation principle of the appearance inspection device in this application embodiment is as follows: During use, the workpiece to be inspected is placed on the base plate 8. The drive handle 92 is rotated, which drives the bidirectional screw 93 to rotate. The bidirectional screw 93 then drives the locking block 91 to move, which in turn drives the elastic pad 94 to move, thus clamping and fixing the workpiece. After completion, the first motor 2 is turned on, driving the lead screw 3 to rotate. The lead screw 3 then moves the drive block 4, adjusting the clamped workpiece to a suitable height. The second motor 13 is then turned on, driving the rotating shaft 14 to rotate. When the rotating shaft 14 rotates, it drives the mounting base 15 and the fixed frame 95 to rotate. The electric push rod 16 is opened, and the electric push rod 16 drives the moving frame 17 to move. The movement of the moving frame 17 makes the slider 19 slide stably inside the slide groove 20. After the first inclined plate 11 rotates, it drives the second inclined plate 12 to rotate. With the rotation of the second inclined plate 12, the fixed frame 95 on one side of the mounting base 15 can be flipped, which facilitates the appearance inspection of the workpiece inside the fixed frame 95 from multiple sides. This solves the tediousness of manually flipping the workpiece for appearance inspection, reduces the workload of the operator, and makes the appearance inspection of the workpiece more effective.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
