[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example 1, by Figure 1 The present invention relates to a visual recognition self-service weighing and food collection device, comprising a base 1, and a weighing mechanism 2 provided on the top of the base 1.

[0023] Specifically, by Figure 2-4 The weighing mechanism 2 includes a vertical cylinder 201 fixed to the top of a base 1. A weighing platform 208 is located inside the vertical cylinder 201. A weighing sensor 2014 is fixedly connected between the bottom of the weighing platform 208 and the inner bottom wall of the vertical cylinder 201. A receiving frame 2019 is located directly above the weighing platform 208, outside the vertical cylinder 201. A plate 203 is placed inside the receiving frame 2019, and the plate 203 has multiple holding slots 202. A bracket 205 is fixedly connected to the top of the base 1. A mounting base 206 is fixedly installed between the bracket 205 and the vertical cylinder 201. A display screen 207 is mounted on the mounting base 206. A turntable 204 is located directly above the plate 203. Two industrial cameras 209 are symmetrically fixedly connected to the bottom of the turntable 204. A rubber pad 2018 is fixedly connected inside the receiving frame 2019, and the plate 203 is located on the rubber pad. The top of the 2018 is equipped with a rubber pad 2018 to protect the plate 203. The side of the receiving frame 2019 is provided with a side groove 2017 to facilitate the placement and retrieval of the plate 203. A drive motor 2013 is fixedly installed on the inner top wall of the bracket 205. A drive shaft 2010 is fixedly connected to the drive motor 2013. The bottom end of the drive shaft 2010 is fixed to the top of the turntable 204. Multiple limiting posts 2011 are fixedly connected to the top of the turntable 204 at equal angles. The top of each limiting post 2011 is provided with a ball bearing 2012 that abuts against the bracket 205. When the turntable 204 rotates, each limiting post 2011 drives each ball bearing 2012 to roll on the bracket 205, thereby limiting the turntable 204 and ensuring the stability of the turntable 204 during rotation. Finally, accurate pricing and improved food retrieval efficiency are achieved.

[0024] In operation, different types of food are first placed in their respective holding slots 202, and then the plates 203 are placed in the receiving frame 2019. The weighing sensor 2014 first detects the weight change and converts the pressure signal into an electrical signal, which is transmitted to the main control system in real time. This triggers the device to start the visual recognition process, and simultaneously starts the drive motor 2013, which drives the drive shaft 2010 to rotate. This, in turn, drives the two industrial cameras 209 to rotate via the turntable 204, capturing multi-angle images of the food in the plates 203. After acquiring high-definition images, these images are transmitted to the AI ​​vision module, which uses image segmentation and feature matching algorithms to identify the food categories and record the corresponding information for each category. After receiving the total weight data from the weighing sensor 2014, the main control system automatically subtracts the pre-stored weight of the empty plate 203 to obtain the net total weight of the meal. Combining the area proportion of each category in the visual recognition results, it allocates and calculates the individual weight of each meal. Then, it calls the pre-stored unit price database of each category to calculate the cost and total amount of each meal. Subsequently, the main control system sends the meal category, weight of each category, unit price and total amount to the display screen 207 to realize the data visualization display. At the same time, it triggers the display screen 207 to generate a dynamic payment code. The user scans the payment code with his mobile phone to complete the payment. After the payment information is verified by the system, the whole process ends and the user can pick up the meal and leave.

[0025] Specifically, by Figure 4 As shown, multiple side blocks 2016 are fixedly connected to the outer side of the weighing platform 208 at equal angles, and multiple bottom rods 2021 are fixedly connected to the bottom of the receiving frame 2019 at equal angles. The bottom end of each bottom rod 2021 passes through each side block 2016 and is fixedly connected to a bottom block 2015. Each bottom rod 2021 is movably connected to each side block 2016. A spring 2020 is fixedly connected between the side block 2016 and the receiving frame 2019. The spring 2020 is sleeved on the outer side of the bottom rod 2021.

[0026] In use, when the plate 203 is placed in the receiving frame 2019, the receiving frame 2019 is impacted and moves downward, causing each bottom rod 2021 to slide downward along each side block 2016. At this time, each spring 2020 is deformed. Since the spring 2020 is elastic, it buffers the impact force and finally ensures that the plate 203 is placed stably.
