Further, the camera module 83 of the material moving mechanism 80 can be used to visually identify whether the product is accurately placed in the receiving tray 200.

[0083] The material transfer mechanism 80 returns to perform the next round of material discharge, identification, and material collection actions;

[0084] For example, after the product on the highest unloading tray 100 on the third tray lifting mechanism 40 completes the burning test, the second tray transporting mechanism 70 drives its transporting assembly to transport the highest unloading tray 100 on the third tray lifting mechanism 40 to the fourth tray lifting mechanism 50, and the fourth tray lifting mechanism 50 drives its tray carrier to drop by one tray height, and the third tray lifting mechanism 40 drives its tray carrier to rise by one tray height;

[0085] When the receiving tray 200 on the second tray lifting mechanism 30 is full of products, the first tray transporting mechanism 60 drives its transporting assembly 63 to transport the highest receiving tray 200 on the first tray lifting mechanism 20 to the second tray lifting mechanism 30, and the second tray lifting mechanism 30 drives its tray carrier to descend by a tray height, and the first tray lifting mechanism 20 drives its tray carrier to rise by a tray height;

[0086] After all product burning tests are completed, replace the products and trays.

[0087] After adopting the above scheme, the present invention adopts four sets of independently controlled pallet lifting mechanisms, which are respectively used for the placement, lifting and lowering of empty material receiving pallets, material receiving pallets containing finished products, material discharging pallets containing unfinished products and empty material discharging pallets, so that the highest pallets and products are kept at the same height position each time, and the pallet sensors are used for sensing, which is conducive to the camera to accurately identify the product, the material transfer mechanism to accurately discharge and collect the material, and the pallet handling mechanism to transport the pallet, while reducing the excessive up and down movement of the material transfer mechanism, thereby improving production efficiency;

[0088] Two sets of independently controlled pallet handling mechanisms are used. The unloading pallet and the receiving pallet are handled separately. The position of the pallet suction nozzle is adjustable, which can be flexibly adapted to different product pallets.

[0089] The material transfer mechanism 80 adopts a four-axis manipulator, which can flexibly move in multiple positions such as the third tray lifting mechanism 40, the lower camera 90, the burning fixture 300, the second tray lifting mechanism 30, and the NG product conveyor belt. At the same time, the application of the four-axis manipulator completely replaces the combination of multiple sets of linear modules, simplifies the equipment structure, and saves the mechanism space;

[0090] The material transfer mechanism 80 can drive the material collection and discharge nozzle assembly 82 to move up and down and rotate thereunder, so as to realize flexible material discharge, material collection and product correction. The material transfer mechanism 80 can separate OK products from NG products to prevent NG products from being mixed with OK products.

[0091] The material discharging and collecting nozzle assembly 82 adopts two sets of independently controlled discharging nozzle modules 822 and collecting nozzle modules 823. The discharging nozzle module 822 is used for discharging materials, and the collecting nozzle module 823 is used for collecting materials. After the material transfer mechanism 80 drives the collecting nozzle module 823 to collect materials, it can rotate to drive the discharging nozzle module 822 to discharge materials, thereby saving product switching time on the burning fixture and improving production efficiency.

[0092] The burning loading and unloading equipment of the present invention can be matched with the existing semi-automatic burning equipment to transform it into a fully automatic burning equipment, so as to make full use of the existing equipment resources, realize the automation of product burning process, and one person can operate multiple devices, thereby reducing the labor cost.

[0093] The above embodiments and drawings do not limit the product form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
