[0096] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0097] The core of the present application is to provide a product automatic detection device which can ensure the detection level and high detection efficiency, and reduce the labor input.

[0098] Please refer to Figures 1-20 The application provides a product automatic detection device for automatically detecting products, which mainly comprises a base 1, a detection module 2, a feeding and discharging module 3, a feeding bin 4 and a discharging bin 5. The detection module 2 is provided with a profiling positioning piece 21 and a negative pressure assembly 22.

[0099] Specifically, the base 1 can be a support plate or a support block. The detection module 2, the feeding and discharging module 3, the feeding bin 4 and the discharging bin 5 are all arranged on the base 1, and the base 1 is used as a support structure of the above modules.

[0100] The detection module 2 is used for detecting the product 10. The detection module 2 is arranged on the base 1. Since the detection module 2 is one of the core modules of the automatic detection device, the detection module 2 can be arranged in the middle of the base 1. The detection module 2 can be a module for detecting the external dimensions. For example, the shape is obtained through a shooting device, and whether the product 10 meets the preset requirements is obtained by comparing the shooting result with the stored data.

[0101] The profiling positioning piece 21 is a profiling piece, specifically a profiling piece of the internal cavity or the shape structure of the product 10, that is, the shape of the profiling positioning piece 21 needs to be the same as the internal cavity shape or the external shape of the product 10 to be detected. The profiling positioning piece 21 is arranged on the detection module 2 and is used for receiving the product 10 transmitted by the feeding and discharging module 3 and achieving cooperative positioning by sleeving the profiling positioning piece 21 with the product 10. It should be noted that the profiling positioning piece 21 can be sleeved with the internal cavity of the product 10 through the protruding shape, or can be sleeved with the external part of the product 10 through the recessed shape. Since the profiling structure is the same as the structure of the product, when the profiling positioning piece 21 is sleeved with the product 10, the positioning of the product 10 can be achieved, and the gap fit or transition fit can be included therebetween.

[0102] The negative pressure assembly 22 is arranged on the profiling positioning piece 21 and is used for applying negative pressure to the product 10 to limit the product 10 from separating from the profiling positioning piece 21. The negative pressure assembly 22 can be directly adsorbed and connected to the product 10, and the two are fixedly connected through negative pressure, or the negative pressure assembly 22 can perform negative pressure suction on the cavity between the sleeved profiling positioning piece 21 and the product 10, to form a negative pressure effect between the profiling positioning piece 21 and the product 10, so that the product 10 will not separate from the profiling positioning piece 21.

[0103] The feeding and discharging module 3 is a mechanical conveying module, which is used for conveying and transporting products, including but not limited to: transferring the product 10 from the feeding bin 4 to the profiling positioning member 21, or from the profiling positioning member 21 to the discharging bin 5. It should be noted that the feeding and discharging module 3 can optionally include a mechanical hand, a conveying device, a position detection sensor, etc., for realizing the automatic operation of the product 10 transfer. The feeding and discharging module 3 can be a device that follows the feeding and discharging operation of a product 10, or the feeding and discharging module 3 can be divided into a feeding module and a discharging module according to the function, and respectively performs the feeding operation and the discharging operation. After the feeding module completes the feeding operation, the feeding of the next product 10 can be performed, thereby accelerating the transfer efficiency of the product 10.

[0104] The product automatic detection device provided in the present application realizes the feeding operation from the feeding bin 4 to the detection module 2 through the feeding and discharging module 3, realizes the first positioning of the product 10 through the cooperation and plug-in of the profiling positioning member 21 and the product 10, so that the product 10 is in a positioned state. At the same time, the adsorption of the product 10 is realized through the negative pressure assembly 22 on the profiling positioning member 21, and the stable setting of the product 10 is realized through the negative pressure effect, so as to ensure that the product will not appear the phenomenon of accidental falling, thereby ensuring the stable and continuous positioning accuracy.

[0105] The product automatic detection device provided in the present application can realize automatic feeding and discharging, can save the labor input, and can realize the positioning effect due to the setting of the profiling positioning member 21 and the negative pressure assembly 22, fully ensures the effective positioning accuracy, and can improve the work efficiency, can provide great convenience conditions for the appearance size detection of the detection module to the product 10, thereby improving the accuracy of the detection result.
