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.
[0025] Please see Figures 1-8This utility model provides a technical solution: a self-service mobile phone case printer inventory identification device, including a mobile phone case vending box 1, an operation panel 2 is provided on the front end of the mobile phone case vending box 1, a mobile phone case placement rack 3 and a control module 6 are provided inside the mobile phone case vending box 1, a partition plate 5 is provided between the operation panel 2 and the mobile phone case placement rack 3, the outer end of the mobile phone case placement rack 3 is fixedly connected to the inner side wall of the mobile phone case vending box 1, a number of classification areas 4 are provided on the mobile phone case placement rack 3, the rear end of each classification area 4 is open, the classification area 4 is used to place mobile phone case products, the rear end of the mobile phone case products is provided with a QR code for identification, a horizontal moving linear motor 7 is provided on the rear side of the mobile phone case placement rack 3, a vertical moving linear motor 8 is provided on the horizontal moving linear motor 7, a picking mechanism 9 is provided on the vertical moving linear motor 8, and a scanning camera 15 is provided on the picking mechanism 9;
[0026] The QR code is located at the opening at the rear end of category area 4. The QR code is used to store product information. The width of the phone case is larger than the opening size at the rear end of category area 4.
[0027] The control module 6 is equipped with a coordinate storage and query module, a product classification and counting module, an alarm module, and a wireless data transmission module. The coordinate storage and query module ensures that after the user selects the desired phone case model through the operation panel 2, the user can query the product and locate the corresponding product coordinates. When the query count is 0, the user is notified that the product is not available. The user's request information is then transmitted to the backend administrator terminal through the wireless data transmission module.
[0028] The picking mechanism 9 includes a fixed plate 10 and a transmission belt 14. The fixed plate 10 is fixed to a longitudinal linear motor 8. A telescopic operating motor 11 is fixedly connected to the side wall of the fixed plate 10. A drive wheel 12 is fixedly connected to the output end of the telescopic operating motor 11. A driven wheel 13 is rotatably connected to the fixed side wall. The drive wheel 12 and the driven wheel 13 are driven by the transmission belt 14. An auxiliary plate 17 is fixedly connected to the side wall of the fixed plate 10. A movable frame 16 is slidably connected to the auxiliary plate 17. The movable frame 16 is fixedly connected to the transmission belt 14. A telescopic plate 18 is fixedly connected to the movable frame 16. A negative pressure suction cup 19 is provided at the lower end of the telescopic plate 18. A negative pressure pump 20 is provided on the auxiliary plate 17. The suction end of the negative pressure pump 20 is connected to the negative pressure suction cup 19. In use, the mobile phone case purchaser... Select the desired phone case model via the operation panel 2. The control module 6 searches for the location of the corresponding phone case model using the coordinate storage and query module. It then controls the horizontal linear motor 7 and the vertical linear motor to move the picking mechanism 9 and the scanning camera 15 to the designated position. The telescopic operation motor 11 drives the drive wheel 12 to rotate, which in turn drives the driven wheel 13 to rotate under the action of the transmission belt 14. This moves the negative pressure suction cup 19 and the telescopic plate 18 above the product. The vertical linear motor 8 then moves the negative pressure suction cup 19 downward. The negative pressure pump 20 is turned on to attach the product to the negative pressure suction cup 19, thus completing the picking process. Finally, the product is moved to the designated position via the picking mechanism 9, the horizontal linear motor 7, and the vertical linear motor 8.
[0029] Both the auxiliary plate 17 and the fixing plate 10 are located on the rear side of the phone case holder 3. The width of the auxiliary plate 17 is smaller than the opening size at the rear end of the sorting area 4, ensuring that the picking mechanism 9 can smoothly move the negative pressure suction cup 19 above the phone case product to be picked up.
[0030] The fixed plate 10 is fixedly connected to the scanning camera 15. The scanning camera 15 is set on the picking mechanism 9 so that the corresponding product can be detected while the device picks up the goods. This enables the sale of mobile phone cases inside the device to detect and count the remaining quantity at the same time, ensuring real-time updates of the back-end data and making it easier for back-end managers to understand the sales details.
[0031] Working Principle: During use, the customer selects the desired phone case model via the control panel 2. The control module 6 uses a coordinate storage and query module to locate the corresponding phone case model. It then controls the horizontal linear motor 7 and the vertical motor to move the picking mechanism 9 and the scanning camera 15 to the designated position. The scanning camera 15 scans the QR code on the back of the phone case, identifying the model. Based on the number of scanned QR codes, the product classification and counting module counts the number of phone cases, ensuring real-time updates of the backend data for administrators to understand sales details. When only one case remains, an alarm is triggered, and the information is transmitted to the administrator terminal via a wireless data transmission module. Simultaneously, the picking mechanism 9 is used to pick up the last product for the user. During the picking process, the telescopic operating motor 11 drives the drive wheel 12 to rotate, and the driven wheel 13 rotates under the action of the transmission belt 14. This moves the negative pressure suction cup 19 and the telescopic plate 18 above the product. The longitudinal linear motor 8 drives the negative pressure suction cup 19 to move downward. The negative pressure pump 20 is turned on to adsorb the product onto the negative pressure suction cup 19, thus completing the picking process. The product is then moved to the designated position by the picking mechanism 9, the lateral linear motor 7, and the longitudinal linear motor 8.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
