Description

Technical Field

[0001] This application relates to the technical field of welding strip flattening devices, and in particular to an openable welding strip flattening device. Background Technology

[0002] A photovoltaic cell string is formed by stacking and welding solder ribbons and cells together in a predetermined order. Adjacent cells are connected together by a set of solder ribbons. Specifically, the first part of the solder ribbon is welded to the front main grid line of the preceding cell, and the second part of the solder ribbon is welded to the back main grid line of the following cell. To ensure the solder ribbon adheres to the main grid lines on the surface of the solar cell, the area between the first and second parts of the solder ribbon needs to be flattened. Traditional solder ribbon flattening devices include a frame, a drive unit, a flattening component, and a support. The drive unit and the flattening component are installed inside the frame, which is fixed to the support. When the flattening device is in operation, the solder ribbon is placed between the flattening component and the support. Then, under the action of the drive unit, the solder ribbon is flattened. During this process, the solder ribbon is compressed, and debris is generated. In subsequent production, this debris affects the flattening device, which in turn affects the flattening quality of the solder ribbon. This necessitates the disassembly and cleaning of the frame and support. However, the frame and support are locked together, making the disassembly efficiency of the flattening device low and the cleaning process inconvenient. Utility Model Content

[0003] The purpose of this utility model is to provide an openable welding strip flattening device to address the defects and shortcomings of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The device includes a stamping assembly and a base assembly. The stamping assembly rotates on the base assembly via a hinge. A snap-fit ​​element is provided between the stamping assembly and the base assembly. The snap-fit ​​element includes a rotating buckle and a connecting buckle. The rotating buckle is disposed in one of the stamping assembly and the base assembly, and the connecting buckle is disposed in the other of the stamping assembly and the base assembly. The rotating buckle and the connecting buckle are interlocked.

[0005] Preferably, the connecting buckle is provided with a locking plate, one end of which abuts against the rotating buckle, and the locking plate makes the rotating buckle and the connecting buckle stably connected.

[0006] Preferably, a locking spring is provided between the rotating buckle and the stamping assembly. The locking spring drives the rotating buckle to rotate and causes one end of the rotating buckle to engage with the connecting buckle.

[0007] Preferably, the base assembly includes a base plate and two support plates, the base plate is located between the two support plates, and baffles are provided on corresponding sides of the base plate, and the lower part of the stamping assembly is located between the two baffles.

[0008] Preferably, the sidewall of the baffle is provided with a plurality of perforations, which allow the welding strip to pass through.

[0009] Preferably, the side wall of the support plate is provided with an embedding groove, and the two ends of the bottom plate are respectively inserted into the embedding grooves of the two support plates.

[0010] Preferably, the support plate includes an upper plate and a lower plate, which divide the embedding groove into two parts.

[0011] Preferably, the stamping assembly includes a frame, a power unit, and a stamping unit, wherein the power unit and the stamping unit are located on the frame, and the stamping unit includes a base, wherein guide slopes are respectively provided at both ends of the base.

[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. After the stamping device completes the flattening process, the rotating buckle can be rotated to separate one end of the rotating buckle from the other end of the connecting buckle. Then the frame and base plate assembly can be rotated to expose the machined surface of the base to the outside. After that, the machined surface of the base can be cleaned, which improves the convenience of cleaning the stamping device. 2. When the rotating buckle and the connecting buckle are engaged, one end of the locking plate presses against the rotating buckle and the connecting buckle, thereby increasing the stability between the rotating buckle and the connecting buckle.
