These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. Example 1

[0025] like Figures 1-3 As shown, a vision inspection device includes a vision inspection module 2 disposed inside a chassis 1, a multi-axis drive mechanism, and a loading platform 3 for carrying and positioning products. The multi-axis drive mechanism can drive the vision inspection module 2 to move horizontally in a first direction and vertically up and down in a second direction. The loading platform 3 can reciprocate below the vision inspection module 2 in a third direction, and the first, second, and third directions are perpendicular to each other. The chassis 1 is provided with a loading port 101 communicating with its interior, and the loading platform 3 can move in the third direction to correspond to the loading port 101.

[0026] Specifically, in actual operation, the operator can place the product to be inspected onto the loading platform 3 through the loading port 101. The product can move along the loading platform 3 to below the vision inspection module 2, and simultaneously move back and forth along a third direction below the vision inspection module 2, allowing the product to be scanned line by line within the inspection area of ​​the vision inspection module 2. As the vision inspection module 2 moves horizontally along the first direction and vertically up and down along the second direction under the drive of the multi-axis drive mechanism, it can flexibly adjust its horizontal position and height from the product to meet the inspection needs of products of different sizes and heights. It also increases the inspection range of the vision inspection module 2 to meet usage requirements.

[0027] It should be noted that in this technical solution, the visual inspection module 2 is existing technology, specifically including an industrial camera, lens, light source assembly, mounting bracket, controller, display, etc. The various components in the visual inspection module 2 can cooperate to acquire images of the product located below it, and simultaneously process and analyze the acquired images to determine the product's quality. Furthermore, in this technical solution, the first direction corresponds to the X-axis direction (including positive and negative X-axis directions) in a Cartesian coordinate system, the second direction corresponds to the Z-axis direction (including positive and negative Z-axis directions) in a Cartesian coordinate system, and the third direction corresponds to the Y-axis direction (including positive and negative Y-axis directions) in a Cartesian coordinate system. The first, second, and third directions are mutually perpendicular.

[0028] Furthermore, such as Figure 2As shown, the multi-axis drive mechanism includes a gantry frame 4 disposed inside the chassis 1, a transfer seat 5 slidably connected to the gantry frame 4 along a first direction, and a mounting seat 6 slidably connected to the transfer seat 5 along a second direction. The vision inspection module 2 is disposed on the mounting seat 6. The transfer seat 5 and the gantry frame 4, and the mounting seat 6 and the transfer seat 5, are slidably connected by linear guide rails 13 to increase the linear motion accuracy of the transfer seat 5 and the mounting seat 6. Simultaneously, two first synchronous pulleys 7 are disposed on the gantry frame 4 along the first direction, and the two first synchronous pulleys 7 are driven and connected by a first synchronous belt 8. The transfer seat 5 is connected to the first synchronous belt 8, and one of the first synchronous pulleys 7 is driven and connected to the output end of a first servo motor 9. That is, the first servo motor 9 can drive the first synchronous pulley 7 to rotate, and when the first servo motor 9 drives the first synchronous pulley 7 to rotate, the first synchronous belt 8 meshing with it can move accordingly, thereby driving the transfer seat 5 to move horizontally along the first direction. Similarly, two second synchronous pulleys 10 are provided on the transfer seat 5 along the second direction. The two second synchronous pulleys 10 are driven and connected by a second synchronous belt 11. The mounting seat 6 is connected to the second synchronous belt 11, and one of the second synchronous pulleys 10 is driven and connected to the output end of the second servo motor 12. That is, the second servo motor 12 can drive the second synchronous pulley 10 to rotate. When the second servo motor 12 drives the second synchronous pulley 10 to rotate, the second synchronous belt 11 meshing with it can also move accordingly, thereby driving the mounting seat 6 to rise and fall vertically along the second direction.

[0029] Furthermore, such as Figure 2 As shown, the loading platform 3 is detachably connected to the slider on the servo slide 14, and the servo slide 14 can drive the loading platform 3 to reciprocate along a third direction. That is, the loading platform 3 is provided with bolts that can be threadedly connected and fixed to the slider, so as to facilitate the replacement of the loading platform 3 to adapt to different specifications of products and improve the flexibility of the device.

[0030] In this embodiment, the loading platform 3 is provided with a contour groove for embedding the product and a positioning pin for positioning the product. The positioning pin can be inserted and engaged with the product. Through the mutual cooperation between the contour groove and the positioning pin, the uniqueness of the product's position on the loading platform 3 can be guaranteed, thereby ensuring the detection accuracy of the vision inspection module 2. Example 2

[0031] like Figure 1As shown, based on Embodiment 1, the chassis 1 is provided with a safety light curtain 15 corresponding to the feeding port 101. The safety light curtain 15 can detect whether there are foreign objects in the area where the feeding port 101 is located. The safety light curtain 15 is electrically connected to the servo slide 14, the first servo motor 9, and the second servo motor 12. When the safety light curtain 15 detects foreign objects, it can stop the servo slide 14, the second servo motor 12, and the second servo motor 12 from operating, so as to ensure the safety of the operator when picking up and putting down materials through the feeding port 101.

[0032] Furthermore, the bottom of the chassis 1 is symmetrically equipped with multiple casters 16 to facilitate the relocation of the vision inspection device. Additionally, a handle 17 is provided on one side of the chassis 1 for easy pushing and pulling.

[0033] Working Principle: First, the operator places the product to be inspected onto the loading platform 3 through the loading port 101. The product moves along with the loading platform 3 to below the vision inspection module 2. Simultaneously, the product reciprocates along a third direction below the vision inspection module 2. Driven by a multi-axis drive mechanism, the vision inspection module 2 moves horizontally along the first direction and vertically along the second direction, allowing the product to be scanned line by line within the inspection area of ​​the vision inspection module 2. The horizontal position and height of the vision inspection module 2 relative to the product can be flexibly adjusted to meet the inspection needs of products of different sizes and heights. This also increases the inspection range of the vision inspection module 2 to meet usage requirements.

[0034] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
