Description

Technical Field

[0001] This utility model relates to the field of visual inspection technology and discloses a visual inspection device. Background Technology

[0002] In industrial production and various fluid transport systems, water pumps are key core equipment. The machining accuracy and assembly quality of their components directly affect the operating efficiency, energy consumption, and service life of the equipment. Therefore, during the water pump manufacturing process, it is necessary to conduct rigorous testing on key indicators such as appearance defects, dimensional accuracy, and assembly integrity to ensure that product quality meets design standards.

Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figure 1-6 A visual inspection device includes: a mounting base 1, a clamping and rotating assembly 2, a top inspection assembly 3, a side inspection assembly 4, a vertical drive assembly 5, and a visual inspection assembly 6. A frame 101 is fixedly connected to the upper end of the mounting base 1. The clamping and rotating assembly 2 is located on the upper end of the mounting base 1 and at the front end of the frame 101, used to fix and drive the water pump workpiece to rotate, so as to achieve multi-directional inspection. The top inspection assembly 3 is disposed on the upper front end of the frame 101, used for visual inspection of the top part of the water pump. The side inspection assembly 4 is disposed on the frame 101, responsible for inspecting the sides of the water pump. The vertical drive assembly 5 is connected to the side inspection assembly 4 to drive the side inspection assembly 4 to move vertically, thereby adapting to the inspection requirements of the sides of the water pump at different heights. There are two visual inspection assemblies 6, which are respectively connected to the top inspection assembly 3 and the side inspection assembly 4, serving as components that directly perform visual inspection tasks.

[0043] This invention, through the cooperation of the top detection component 3 and the side detection component 4, combined with the clamping and rotating component 2 driving the water pump to rotate, can simultaneously detect the top and sides of the water pump without the need for multiple loading and unloading of workpieces. This solves the problem of the single detection direction in traditional equipment, achieving omnidirectional visual inspection of the water pump and improving the comprehensiveness of the inspection. Simultaneously, the vertical drive component 5 can drive the side detection component 4 to move vertically, allowing the side detection component 4 to flexibly adjust its position according to the height of the water pump, ensuring that the visual inspection component 6 is always in the optimal detection position. This improves the accuracy of the inspection, reduces manual intervention, and enhances the automation level of the device.

[0044] Specifically, the clamping and rotating assembly 2 includes a fixture mounting plate 201 and a protective shell 204. The upper and lower ends of the fixture mounting plate 201 are respectively fixedly connected to a three-axis manipulator 202 and a drive mechanism 203. The three-axis manipulator 202 can flexibly fix the water pump, while the drive mechanism 203 provides power for the rotation of the fixture mounting plate 201. The protective shell 204 is fixedly connected to the upper end of the mounting base 1, and the upper surface is provided with a circular groove to facilitate the rotation of the fixture mounting plate 201. The circular groove provides space for the rotation of the fixture mounting plate 201, ensuring the smooth operation of the rotation process. At the same time, the protective shell 204 protects the internal drive mechanism 203 and other components.

[0045] Through the above technical solution, the clamping and rotating assembly 2 can fix the water pump and drive the water pump to rotate, so as to conduct a comprehensive inspection of the side of the water pump.

[0046] Specifically, the visual inspection component 6 includes a camera mounting plate 601. A light source 602 and a camera 603 are fixedly connected to the two ends of the camera mounting plate 601, respectively. The camera 603 is the core component for performing visual inspection and is used to capture image information of the part of the water pump to be inspected. The light source 602 provides sufficient and uniform light for the camera 603 to take pictures, ensuring stable lighting conditions in the shooting environment.

[0047] Through the above technical solution, the camera 603 can capture image information of the part of the water pump to be inspected for subsequent inspection.

[0048] Specifically, the top detection component 3 includes: a slider 301, a first mounting plate 303, and a first lifting structure 302 for driving the slider 301 to move. The front end of the slider 301 is fixedly connected to the camera mounting plate 601. The front and rear ends of the first mounting plate 303 are respectively fixedly connected to the outer frame of the first lifting structure 302 and the frame 101, so as to stably install the entire top detection component 3 on the frame 101.

[0049] Through the above technical solution, the first lifting structure 302 drives the slider 301 to move, and the slider 301 can drive the vision detection component 6 to move synchronously, thereby adjusting the position of the vision detection component 6 in the vertical direction to adapt to the detection requirements of the top of the water pump at different heights.

[0050] Specifically, the side detection component 4 includes: a linear bearing housing 401, a first drag chain 405, and a moving frame 402. The moving frame 402 is provided with a transverse drive structure 403 for driving the linear bearing housing 401 to move. The transverse drive structure 403 drives the linear bearing housing 401 to move, which can drive related components and the vision detection component 6 to adjust their positions in the horizontal direction. A first groove mounting plate 404 is fixedly connected to the upper end of the linear bearing housing 401. A connecting plate 407 is fixedly connected to the right side of the front end of the first groove mounting plate 404. An extension plate 406 is fixedly connected to the upper end of the moving frame 402, and a rotating structure 8 for controlling the rotation of the vision detection component 6 is fixedly connected to the front end to adjust the detection angle. The first drag chain 405 is located inside the first groove mounting plate 404, and its left and right ends are fixedly connected to the first groove mounting plate 404 and the extension plate 406, respectively. The first drag chain 405 can keep the linear bearing housing 401 moving smoothly.

[0051] Through the above technical solution, the lateral drive structure 403 drives the linear bearing seat 401 to move, which can drive the visual inspection component 6 to adjust its position in the horizontal direction. In conjunction with the rotating structure 8, the visual inspection component 6 is controlled to rotate, realizing the flexible adjustment of the visual inspection component 6 in the horizontal direction and angle, which greatly expands the detection range.

[0052] Specifically, the vertical drive assembly 5 includes: a second mounting plate 501, the rear end of which is fixedly connected to the inner wall of the frame 101, providing a stable mounting base for the entire vertical drive assembly 5; a second cable tray mounting plate 502 and a second lifting structure 504, which are fixedly connected in parallel to the front end of the second mounting plate 501; and a second drag chain 503, located on the second cable tray mounting plate 502 and fixedly connected at its upper and lower ends to the connecting plate 407 and the second cable tray mounting plate 502, respectively, for maintaining the stability of the movement of the side detection assembly 4.

[0053] Through the above technical solution, the vertical drive component 5 can accurately drive the side detection component 4 to move in the vertical direction. In conjunction with the side detection component 4's own lateral and rotational adjustment, the detection range of the visual detection component 6 is further expanded.

[0054] Specifically, a front guard plate 7 is fixedly connected to the front end of the frame 101. A display mounting slot 701 is provided on the front surface of the front guard plate 7. A display pressure plate 702 is fixedly connected inside the display mounting slot 701. The display can be placed in the display mounting slot 701 and fixed on the display pressure plate 702 so as to observe the image collected by the vision detection component 6 and to set the image acquisition.

[0055] Specifically, the left end of the frame 101 is fixedly connected to the electrical control box 102 and the right end is provided with an acrylic door panel 103. The electrical control box 102 integrates the electrical control components, circuits and related control systems of the device, and is the control core of the entire visual inspection device. The acrylic door panel 103 is made of transparent material, which makes it convenient to observe the operation of the device.

[0056] In use, the water pump to be tested is first placed on the fixture mounting plate 201 of the clamping and rotating assembly 2. The three-axis robot arm 202 firmly clamps the water pump, and the drive mechanism 203 drives the fixture mounting plate 201 to rotate within the circular groove of the protective shell 204 to adjust the water pump's posture. At the same time, the first lifting structure 302 of the top detection assembly 3 drives the slider 301 to move the vision detection assembly 6 to the corresponding height at the top of the water pump. The light source 602 provides supplementary lighting, and the camera 603 captures images of the top. The side detection assembly 4 moves vertically under the drive of the second lifting structure 504 of the vertical drive assembly 5. In conjunction with the horizontal drive structure 403 within the moving frame 402, the linear bearing seat 401 is adjusted horizontally. The rotating structure 8 controls the rotation of the vision detection assembly 6 to achieve multi-directional detection of the water pump's side. The detection data is processed by the electrical control box 102 and displayed on the display in the display mounting slot 701. The operator can observe the internal detection status through the acrylic door panel 103. After the detection is completed, the three-axis robot arm 202 is released, and the water pump is removed to complete the detection process.
