[0028] Example 1

[0029] like Figures 1 to 8 As shown, the specific embodiment of the present invention provides a high-speed circulation production line for printing battery cells, which is used to improve the stability of material transmission and automatically process materials, thereby improving production efficiency and production quality; it specifically includes a loading unit, a processing unit and a unloading unit; the loading unit includes a raw material bin 100, above which are provided a loading arm 200 and a loading transfer arm 300 arranged from upstream to downstream, and a carrier exchange platform 400 is provided between the loading arm 200 and the loading transfer arm 300; the processing unit The element includes a circulating magnetic levitation conveying unit 500, and a cleaning unit 600, a printing unit 700, a pre-curing unit 800 and a deep curing unit 1000 arranged in sequence from upstream to downstream of the circulating magnetic levitation conveying unit 500; the unloading unit includes a clinker bin 1100 located downstream of the deep curing unit 1000, and a unloading transfer arm 1200, a unloading transfer table 1300, a clinker buffer table 1400 and a unloading arm 1500 are arranged in sequence between the deep curing unit 1000 and the clinker bin 1100.

[0030] Through the above-mentioned settings, the production line provided in this embodiment automatically completes multiple processing steps after completing loading through the loading unit, and finally realizes automatic unloading through the unloading unit; the loading unit uses the loading arm 200 to transfer the material in the raw material bin 100 to the carrier exchange platform 400, and the material is transmitted to the processing unit through the loading transfer arm 300. During the continuous processing process, the processing unit uses the circulating magnetic levitation conveying unit 500 to circulate the material in a magnetic levitation conveying manner, which greatly reduces the instability of the battery cell caused by multiple handling of the battery cell; the cleaning unit 600, printing unit 700, pre-curing unit 800, throwing unit 900 and deep curing unit 900 located on the conveying line of the circulating magnetic levitation conveying unit 500 The chemical unit 1000 completes all processing procedures by successively cleaning, printing, pre-curing, throwing and deep-curing the materials, realizing continuous and automatic processing of each process flow without the need for human participation and work, which greatly improves production efficiency and stability; after the processing is completed, the unloading unit automatically unloads, transfers and finally transfers the clinker to the clinker bin 1100 to complete the clinker collection. The entire production line has a high degree of automation and stability, which can significantly improve production efficiency. In actual production applications, this production line can increase the production capacity from 900pcs / H to 3500pcs / H; through the optimization of the overall structural design, the time for changing the production model of the whole machine is shortened to 10min, which can significantly improve the production efficiency of the enterprise.

[0031] To improve curing quality, this embodiment features an inspection camera unit 3200 between the pre-curing unit 800 and the material throwing unit 900. The material throwing unit 900 is located downstream of the inspection camera unit 3200. The inspection camera unit 3200 performs image inspection on the processed material, and any unqualified products are removed through the material throwing unit 900, thereby ensuring the quality of the raw material. To improve the continuity of material transmission on the production line, this embodiment also features a docking station 3300 upstream of the cleaning unit 600 and downstream of the material throwing assembly within the circulating magnetic levitation conveyor unit 500.

[0032] Example 2

[0033] This embodiment further optimizes the structures of the loading and unloading units. Specifically, the raw material bin 100 is provided with a raw material handling arm 1900 for transferring materials to the upper feeding arm 200. The raw material handling arm 1900 can transport a full tray of battery cells to the battery cell handling position, which is convenient for subsequent transfer and transmission by the loading arm 200. In actual application, the raw material bin 100 and the clinker bin 1100 are arranged in pairs. A pair of conveyor belts 1600 is provided in each raw material bin 100 and clinker bin 1100.

A grating assembly 1800 is also provided on the outside of the conveyor belts 1600. In this way, the width adjustment motor assembly 1700 located between the two raw material bins 100 and clinker bins 1100 can adjust the width of each pair of conveyor belts 1600, and then adaptively adjust according to the material specifications, thereby improving the applicable range of material transportation.

[0034] As mentioned above, after the material processing is completed, it is transferred to the clinker bin 1100. In order to further improve the transportation efficiency, this embodiment also provides a clinker transport arm 2000 in the clinker bin 1100 for transferring the clinker material to the clinker bin 1100.

[0035] When transferring materials, the loading arm 200 and the unloading arm 1500 need to transfer them through the transfer arm structure. To improve transfer efficiency, this embodiment has front and rear linear motor assemblies 2100 installed between the loading arm 200 and the loading transfer arm 300, and between the unloading arm 1500 and the unloading transfer arm 1200.

In this way, each screw module can push and position the material on the horizontal plane, ensuring that the material is in the predetermined transmission position.

[0038] A post-NG caching platform is provided between the unloading transfer table 1300 and the unloading transfer arm 1200. The materials can be cached through the cache platform to improve the continuity and stability of the transfer transportation.
