Description

Technical Field

[0001] This application relates to the field of stamping equipment technology, and in particular to a modular pneumatic stamping device. Background Technology

[0002] In photovoltaic cell strings, adjacent cells are usually connected by welding strips. Before the welding strips and cells are laid and stacked, a special stamping device (i.e., welding strip flattening device) is sometimes used to flatten the pre-set parts of the welding strips. A sealed welding strip shaping machine is disclosed in the prior art Chinese utility model patent (authorization announcement number CN215355427U). Its structure includes a base, an outer protective cover, a connecting lever, a shaping mechanism and a double-acting cylinder. The outer protective cover includes an upper protective cover and a lower protective cover. The double-acting cylinder is installed in the upper protective cover, the shaping mechanism is located in the lower protective cover, and the connecting lever links the shaping mechanism and the double-acting cylinder.

[0003] However, the drawback of the above-mentioned prior art is that the upper protective cover of the stamping device (forming machine) is machined as a single piece, and the upper protective cover has multiple parallel piston chambers. The piston of the double-acting cylinder is installed in the piston chamber. Under long-term operation of the stamping device (forming machine), the inner wall of the piston chamber will be worn. In order to keep the stamping device (forming machine) working normally, the entire upper protective cover needs to be disassembled and replaced, which increases the repair cost of the stamping device (forming machine).
