[0002] Electric vehicles are a common mode of transportation, and they are generally equipped with displays to show various status information of the vehicle in real time. These displays typically integrate multiple LEDs; when different status information needs to be displayed, the corresponding LEDs illuminate, emitting clearly distinguishable colors to provide users with intuitive and rich visual feedback. Therefore, the displays of electric vehicles must be tested before leaving the factory to determine if there are any missing or faulty LEDs, and to ensure that the color emitted by each LED is correct.

[0003] Traditional testing methods rely on manual observation, which is not only inefficient but also harmful to the eyes, potentially affecting vision health in the long run. More importantly, when faced with large-scale testing tasks, manual observation is prone to fatigue, leading to misjudgments and missed detections, thus affecting product quality control and user experience.

[0035] like Figure 1-6 As shown, this embodiment provides a visual inspection device, which includes an inspection table 1, an inspection fixture 2, and an inspection camera 3, used to photograph and inspect a workpiece 4 to be inspected. The inspection table 1 is supported at a set height by a frame 13. A supporting vertical plate 11 is provided below the inspection table 1, preferably in an enclosing configuration. A supporting horizontal edge 111 is also provided on the inner side of the supporting vertical plate 11. The supporting vertical plate 11 and the supporting horizontal edge 111 form a placement cavity 112, which can be cuboid or cylindrical, etc. The inspection fixture 2 can be placed precisely within the placement cavity 112, supported by the supporting horizontal edge 111. The workpiece 4 to be inspected is placed on the inspection fixture 2, with the surface to be inspected of the workpiece 4 facing downwards. The inspection camera 3 is positioned below the inspection fixture 2, facing the workpiece 4, and is used to photograph and inspect the surface to be inspected of the workpiece 4. The visual inspection device also includes a detection module for analysis and comparison, such as comparing the captured image with a preset image to determine if there are any differences, thereby determining whether workpiece 4 is faulty. Workpiece 4 can be, but is not limited to, a display screen, thus enabling the determination of whether there are problems such as missing lights, broken lights, or incorrect light colors, ensuring product quality control.

[0036] Thus, the visual inspection device provided in this embodiment inspects the workpiece 4 using the inspection camera 3, improving efficiency, reducing harm to the human eye, and increasing inspection accuracy. Furthermore, in this embodiment, the supporting vertical plate 11 is positioned below the inspection table 1, meaning that the placement cavity 112 is formed by a downward recess in the inspection table 1. The supporting vertical plate 11 can be welded and fixed to the inspection table 1, and the supporting horizontal edge 111 can be bent to form the bottom end of the supporting vertical plate 11. This makes the height of the inspection fixture 2 convenient for manual operation after placement. Moreover, the placement cavity 112 can provide a certain positioning function for the inspection fixture 2, ensuring that it is aligned with the inspection camera 3 below. The supporting vertical plate 11 also reduces interference from other light sources, thereby ensuring more realistic and accurate photographs. In addition, the inspection fixture 2 in this embodiment can be directly placed in the placement cavity 112. When it is necessary to change to a different specification of workpiece 4 to be inspected, the entire inspection fixture 2 can be replaced directly, making replacement convenient and efficient.

[0037] Since the supporting vertical plate 11 has a certain vertical length and needs to support the testing fixture 2, in this embodiment, a reinforcing member 12 is welded between part of the outer wall of the supporting vertical plate 11 and the testing table 1 to improve the strength. The reinforcing member 12 can be, but is not limited to, pipe fittings, plates, etc.

[0038] like Figure 4 As shown, the inspection fixture 2 includes a support frame 21 and a fixture table 22. The support frame 21 is adapted to the placement cavity 112 and supports the fixture table 22. Handle holes 211 are provided on both sides of the support frame 21 for easy loading and unloading. Furthermore, the fixture table 22 is provided with a placement groove 221 for placing the workpiece 4 to be inspected. Preferably, the placement groove 221 is a bearing edge formed by a downward indentation from the upper surface of the fixture table 22, corresponding to the edge of the workpiece 4, while ensuring that the portion of the workpiece 4 to be inspected is not obstructed and can still be captured by the inspection camera 3.

[0039] Furthermore, a liftable connecting plate 23 is provided on the tooling table 22. The connecting plate 23 is preferably made of insulating material such as resin. An electrical connector 231 is provided through the connecting plate 23. The upper end of the electrical connector 231 is connected to the power supply 26 and the control module (not shown in the figure). The lower end of the electrical connector 231 can be disengaged from or connected to the connecting terminal 41 on the workpiece 4 when the connecting plate 23 is raised or lowered. Thus, when the connecting plate 23 is raised, the workpiece 4 can be placed. When the connecting plate 23 is lowered, the workpiece 4 can be powered on. The control module is programmed to control the workpiece 4 to work in a corresponding state. For example, when the workpiece 4 is a display screen, the display screen is controlled to light up in a preset state. In this embodiment, a manual operation structure is provided to control the raising and lowering of the connecting plate 23. The handle 24 is pulled up / down, and the lower end of the handle 24 drives the connecting plate 23 to rise / fall. A guide rod 25 is also provided on the tooling table 22 to guide the connecting plate 23. Of course, in other embodiments, an electric lifting method can also be used.

[0040] To facilitate the handling of workpiece 4, this embodiment also provides a pick-up slot 222 on both sides of the placement slot 221. When it is necessary to remove workpiece 4, it can be lifted by contacting the workpiece 4 from both sides. Alternatively, this embodiment provides a front opening on the support frame 21. When it is necessary to remove workpiece 4, it can be lifted from the bottom of the workpiece 4 by reaching into the front opening on the detection table 1. Furthermore, to prevent objects such as the control module and the remote key for starting from falling out of the front opening, a corresponding guard 14 is provided on the detection table 1.

[0041] like Figure 1 , 5 As shown, in this embodiment, a tooling pressure plate 15 is also provided on the testing platform 1. When the testing tool 2 is placed into the placement cavity 112, its top is limited. The tooling pressure plate 15 includes a horizontal connecting edge 151, a vertical extending edge 152, and a horizontal pressing edge 153. The horizontal connecting edge 151 is used to connect with the testing platform 1, the vertical extending edge 152 extends upward to adapt to the height of the testing tool 2, and the horizontal pressing edge 153 is used to press the tooling platform 22 of the testing tool 2. The horizontal connecting edge 151 is provided with an elongated hole 1511. The bolt passes through the elongated hole 1511 and is connected to the testing platform 1. By providing the elongated hole 1511, the tooling pressure plate 15 can move left and right without completely removing the bolt, thus making it more convenient to pick up and put down the testing tool 2. Preferably, one testing tool 2 is provided with two tooling pressure plates 15, which limit the movement on both sides.

[0042] like Figure 6As shown, the inspection camera 3 is vertically adjustable and mounted on the slide rail 31 of the frame 13. Before inspection, the height of the inspection camera 3 is adjusted vertically to ensure it can capture clear images. The vertical adjustment structure of the inspection camera 3 can be manual, and locked in place by a locking knob when adjusted to a certain height; or it can be electrically adjusted, for example, by a servo push rod. Furthermore, the inspection camera 3 is also horizontally extended and mounted directly below the workpiece 4 via an extension plate 32, so that the inspection camera 3 can be positioned approximately at the center of the surface to be inspected on the workpiece 4 from either a top-down or bottom-up perspective. Furthermore, the inspection table 1 is also equipped with a display 18, and a drawer 19 is located below the inspection table 1. The drawer 19 contains a keyboard, mouse, and other components for easy operation.

[0043] like Figure 1 As shown, in this embodiment, a sealing plate 16 is also provided around the perimeter below the detection platform 1. The sealing plate 16 is provided around the perimeter and bottom of the frame 13 to block light as much as possible, thereby further reducing the interference of external light on the photography. Of course, the sealing plate 16 also plays a certain protective role.

[0044] Preferably, the visual inspection device of this embodiment includes two inspection fixtures 2 and two inspection cameras 3. Two placement cavities 112 are correspondingly formed on the inspection table 1. The inspection fixtures 2, inspection cameras 3, and placement cavities 112 are arranged in a one-to-one correspondence. The two inspection fixtures 2 are used to place workpieces 4 of the same specifications to be inspected. Since taking pictures and analyzing data requires a certain amount of time, this embodiment sets up two sets of inspection fixtures 2, inspection cameras 3, and placement cavities 112, forming a dual-station inspection device. This allows a new workpiece 4 to be inspected to be placed on the other set while one set is taking pictures and analyzing data, thereby improving the overall inspection efficiency. Furthermore, a partition plate 17 is provided below the inspection table 1 between the two inspection cameras 3 to reduce mutual interference.

[0045] As can be seen from the above, the visual inspection device provided in this embodiment can perform visual inspection of the workpiece to be inspected efficiently and accurately, and also has the advantages of convenient operation and stable structure.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
