Electroplating device

The invention discloses an electroplating device, and relates to the technical field of solar cell electroplating. The electroplating device comprises a support, a gate mechanism and a cathode assembly, an electroplating bath is arranged on the support, an anode plate and electroplating liquid are arranged in the electroplating bath, and a first opening is formed in one end, in the first direction, of the electroplating bath; the gate mechanism comprises a first gate and a second gate which are arranged in a spaced mode in the first direction, the first gate and the second gate are both movably connected to the support, and the first gate and the second gate can block the first opening when descending; the cathode assembly comprises a cross beam, the cross beam extends in the second direction and can bear a battery piece, the cross beam can pass through the gate mechanism in the first direction and move into the electroplating bath, the battery piece enters the electroplating liquid and is spaced from the ano
