The top shooting group and the side shooting group are connected to a computer to upload the pictures for calculation. The number of IC chips and abnormal points on the tray are output by comparing the pictures, thereby achieving the purpose of automatic counting. This can greatly avoid human errors, reduce human workload and operational difficulty, and further improve the degree of work standardization and automation. (2) The present invention installs a fill light group on the top of the counting area, and uses the fill light group to illuminate the tray, thereby improving the clarity of the photos taken by the shooting group. At the same time, by designing the fill light group into a structure in which a light plate, a lamp holder, a fill light and a driving part cooperate with each other, it is convenient to adjust the fill light position of the fill light by the driving part 2 during use, thereby meeting the purpose of clearly photographing trays of different models.

[0032] (3) The present invention installs a movable frame on the inventory area, and installs the side shooting group through the movable frame. When it is necessary to shoot through the side shooting group, the height can be adjusted by cooperating with the movable frame and the driving member. At the same time, the movable frame is designed to have a three-phase coordinated structure of a lifting seat frame, an angle seat frame and a driving member. When it is convenient to use, the angle between the lifting seat frame and the angle seat frame can be changed by the driving member three, thereby changing the shooting angle of the side shooting group, which is easy to meet different usage requirements.

[0060] The device provided in the embodiment of the present invention has the same implementation principle and technical effects as those in Example 1. For the sake of brief description, for matters not mentioned in this embodiment, reference may be made to the corresponding contents in Example 1.

[0061] A counting method for IC counting equipment based on machine learning includes the following steps: S1: placing trays of different models on a moving seat, moving the trays to the counting area of ​​the equipment frame in turn through the moving seat, starting the fill light group and taking pictures through the top shooting group, adjusting the position of the fill light through the second driver, taking multiple groups of pictures at different fill light positions, and each group can be moved the same distance based on the previous group through the second driver. S2: comparing the photos of each model of tray to determine the clearest photo, and the fill light point corresponding to the photo is the best shooting fill light point. The best shooting fill light point is recorded on the computer, and the photo taken at the best shooting fill light point for the first time is stored as a learning model. Different models of trays can correspond to different fill light data to form a database. The information of each group of databases includes the tray model, the best fill light point fill light position, and the learning model photo data. S3: When inventory is required during the processing, you only need to identify the corresponding Tray model to automatically adjust the fill light to the optimal fill light position. Then, the top shooting group will shoot the Tray, and the photos taken will be compared with the learning sample photos. The number of IC chips with or without IC chips can be determined based on the different reflections (implemented through the image comparison module). S4: When the top shooting group cannot clearly identify the IC chip in the Tray, the side shooting group can be started to assist in shooting. The top photos and side photos can be used to further improve the accuracy of the photos and the depth of machine learning, so that the program has the function of detecting stacked materials at a certain tilt angle of the Tray. When the Tray has a certain tilt angle, the side shooting group can synchronously adjust the height and angle of use to ensure the clarity of the photos, which is convenient for later comparison.

[0062] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
