Seal welding technology for electroplating anode bag

Abstract

The invention discloses a seal welding technology for an electroplating anode bag. The seal welding technology for the electroplating anode bag comprises the following steps: (1) selecting a corresponding ultrasonic welding die according to the size and the shape of the anode bag; (2) placing and fixing the anode bag to be welded in the welding die; (3) press fit. In the step (3), the fusion welding time of ultrasonic is 20-300s during the ultrasonic press fit, the hardening time after the fusion welding is 0.3-15s and the press fit thickness is 3-10mm. By using an ultrasonic welding technology and fitting with the corresponding welding thickness, fusion welding time and hardening time, the edge of the welded anode bag can be sealed completely with no leakage phenomenon occurring, and the leakage of anode mud and the anode mud pollution of an electroplating tank caused by the conventional anode bag welding technology can be absolutely eradicated, so that the technology can help to improve the quality of the electroplating effectively.

Description

technical field [0001] The invention relates to an anode bag sealing and welding process for electroplating, and belongs to the technical field of anode bag sealing welding machines. Background technique [0002] The anode bag, also known as the titanium blue bag, is a bag made of a PP or PE fiber filter cloth or PP filter paper, which is used to cover the outside of the electroplated titanium blue to prevent the anode in the titanium blue The sludge enters the solution in the electroplating tank. Generally, clean the anode bag and titanium basket every half a month to a month, and replace the damaged anode bag to ensure that the plating solution and plating tank are free from pollution. [0003] However, the edge of the traditional anode bag is usually sewn with needles and threads. No matter what kind of sewing process is used, there will be a certain gap at the edge. If the sealing is not good, copper slag will leak from the gap, pollute the electroplating tank, and affe...

[0003] However, the edge of the traditional anode bag is usually sewn with needles and threads. No matter what kind of sewing process is used, there will be a certain gap on the edge. If the sealing is not good, copper slag will leak from the gap, pollute the electroplating tank, and affect the quality.
