[0032] Please refer to Figures 1 to 4 In a preferred embodiment, the visual detection equipment of the present application mainly comprises a positioning platform 1, a driving mechanism 2 and a visual detection mechanism 3. Among them, at least one positioning mechanism 11 for fixing the product to be detected is arranged on the positioning platform 1. The driving mechanism 2 is connected to the positioning platform 1, which is used to drive the positioning platform 1 to move along the first direction X, so as to switch the positioning platform 1 between the operation position 21 and the detection position 22. The visual detection mechanism 3 is arranged at the detection position 22, and the visual detection mechanism 3 comprises a side detection assembly 31 and a top detection assembly 32 arranged one by one corresponding to the positioning mechanism 11. The side detection assembly 31 is movably arranged on one side of the moving path of the positioning mechanism 11, and the top detection assembly 32 is movably arranged above the moving path of the positioning mechanism 11.

[0033] Exemplarily, the driving mechanism 2 can adopt an existing linear driving device, for example, a single-shaft servo motor, the output end of which is connected with the positioning platform 1. The positioning platform 1 is provided with a plurality of positioning mechanisms 11 for placing products to be detected. In the embodiment, the positioning mechanisms 11 are two, which are arranged at the upper end face of the positioning platform 1 along the second direction Y. One end of the moving path of the positioning platform 1 is defined as an operation position 21, and the other end is defined as a detection position 22. The driving mechanism 2 can drive the positioning platform 1 to switch between the operation position 21 and the detection position 22. When the positioning platform 1 is located at the operation position 21, an operator can load products to the positioning mechanisms 11 or take out the products that have completed detection from the positioning mechanisms 11. When the positioning platform 1 is located at the detection position 22, the visual detection mechanism 3 can perform visual detection on the products.

[0034] As can be seen from the above and the technical solutions, the positioning platform 1 is provided with a plurality of positioning mechanisms 11, which can fix the products, ensure the stability of the products during detection, and improve the accuracy of detection.

The visual detection mechanism 3 includes a side detection assembly 31 and a top detection assembly 32, which can simultaneously perform visual shooting on the side and top of the products, thereby saving detection time, improving detection efficiency, avoiding adjustment of the position of the products, ensuring the stability of the position of the products, and improving the accuracy of detection.

[0035] Please refer to Figure 2 The positioning mechanism 11 includes a positioning seat 111, at least one pressing assembly 112 arranged on the positioning seat 111, and a connecting assembly 113 arranged adjacent to the positioning seat 111.

The connecting driving member 1131 can adopt an existing linear driving device, such as a linear cylinder. When the products are placed in the positioning seat 111, the driving member can drive the connecting head 1132 to approach or move away from the positioning seat 111, so that the connecting head 1132 is electrically connected or disconnected with the products.

[0043] In this embodiment, the second visual inspection component 323 is slidably connected to the second mounting base 322, and the second visual inspection component 323 can slide relative to the second mounting base 322 along a third direction Z. The ability of the second visual inspection component 323 to slide relative to the second mounting base 322 along a third direction Z facilitates adjustment of the distance between the second visual inspection component 323 and the product, allowing the focal length of the second visual inspection component 323 to be adapted to different product models, thus improving the applicability of the testing device.
