[0064] The existing tunnel furnace drying method for micro-batteries has problems such as the inability to quickly schedule the drying chambers according to the production progress, resulting in low production efficiency, poor temperature uniformity, and low thermal efficiency.

[0065] To address the above problems, a tunnel-type dryer for micro batteries is proposed.

[0067] In this embodiment, by setting up a scheduling mechanism 400, the battery trays in each drying equipment 200 can be scheduled in a timely manner according to the production progress, thereby improving production efficiency. By setting up multiple support plates 110 on the tunnel frame 100, each support plate 110 includes multiple working positions, and the drying equipment 200 at multiple working positions can operate simultaneously, greatly improving space utilization and production efficiency. By setting up a flat tube structure, the weight of the drying equipment 200 is reduced while avoiding structural deformation, thus solving the problems of existing tunnel furnace drying equipment for small and micro batteries, which cannot quickly schedule each drying chamber according to the production progress, resulting in low production efficiency, poor temperature uniformity, and low thermal efficiency.

[0068] In this embodiment, the tunnel frame 100 can be divided into multiple layers, preferably two layers. Each layer of support plate 110 is preferably configured with four working positions for placing four drying devices 200.

[0069] Two scheduling mechanisms 400 are installed on the crossbeam above each layer of drying equipment 200 to schedule the tray batteries in each row of drying equipment 200. Specifically, they transfer the battery trays from the tray assembly station to the drying equipment 200, or transfer the dried battery trays to the tray disassembly station.

[0070] In one possible implementation, the scheduling mechanism 400 includes a first moving track 410 and a gripping device 420; the gripping device 420 is mounted on the first moving track 410 and is used to move the gripping device 420 between the loading position and the working position; the gripping device 420 is used to grip the battery tray.

[0079] In this embodiment, the flat tube structure can reduce the weight of the shell while ensuring the shell strength, which is beneficial to the lightweighting of the drying chamber.

[0080] In this embodiment, the drying equipment 200 also includes an exhaust port 201 and a nitrogen port 202. The exhaust port 201 can be connected to an external vacuum device, allowing the moisture discharged during drying to be released in a timely manner, greatly improving drying efficiency. The nitrogen port 202 can be repeatedly filled with nitrogen to create a vacuum, allowing moisture to be released in a timely manner. In addition, the nitrogen environment can protect the battery.

[0085] In this embodiment, the second lifting mechanism 320 lifts and opens the sealing door 230, then moves it to the workstation of another drying chamber via a sliding track. The process is reversed when closing. In this embodiment, the second lifting mechanism 320 can detachably connect the sealing doors 230 of multiple drying devices 200 via connecting blocks 2311. After operating on one sealing door 230, it can also operate on the other drying devices 200 in that row.

[0086] The tunnel dryer for micro batteries implementing this utility model improves production efficiency by setting up a scheduling mechanism 400 to schedule the battery trays in each drying device 200 in a timely manner according to the production progress. By setting up multiple support plates 110 on the tunnel frame 100, each support plate 110 includes multiple working positions, and the drying devices 200 at multiple working positions can operate simultaneously, which greatly improves space utilization and production efficiency. By setting up a flat tube structure, the weight of the drying device 200 is reduced while avoiding its structural deformation. This solves the problems of existing tunnel furnace drying equipment for micro batteries, which cannot quickly schedule the drying chambers according to the production progress, resulting in low production efficiency, poor temperature uniformity, and low thermal efficiency.
