Technical Field
The invention belongs to the technical field of welding, and particularly relates to a net pressing tool.
Background
At present, for welding photovoltaic cell pieces, especially for welding circular welding strips, the following two welding modes are generally adopted:
(1) a plurality of rows of pressing pins are arranged below the lamp box, and in the welding process, the welding strip is pressed by the pressing pins so as to ensure the relative position relationship between the welding strip and the photovoltaic cell;
(2) Pressing the welding strip in a full-screen mode so as to ensure the relative position relationship between the welding strip and the photovoltaic cell;
the first approach has the following disadvantages: light is easy to block, and the surface temperature of the photovoltaic cell is influenced, so that the cold joint phenomenon is caused. And the photovoltaic cell piece is silicon-based, and it has hard fragile physical characteristic, and multirow tucking is pressed on the photovoltaic cell piece, causes the photovoltaic cell piece surface uneven stress easily to increase the hidden risk of splitting of photovoltaic cell piece. In addition, because the high temperature is needed to ensure that the tin on the surface of the welding strip is melted in the welding process, the temperature far exceeds the limit temperature born by the spring inside the pressing pin, the spring can be failed in a short time, and the spring needs to be replaced frequently or a high-temperature-resistant spring is directly used, so that the cost is increased.
The second mode has the following disadvantages: the solder strip can have certain stress in the process treatment (tensile alignment, bending etc.) in the front, and the location of assurance solder strip that can not be fine is singly leaned on the pressure effect of silk screen, and especially in welding process, high temperature can make solder strip internal stress release, and the solder strip can overcome the pressure effect of silk screen and certain bending appears to make the position relation between solder strip and the photovoltaic cell certain deviation appear, can not guarantee fine welding quality.
