Two circuit board accommodating grooves are provided on the pallet for placing current boards, and the circuit board accommodating grooves penetrate the pallet. Circuit board placement blocks are symmetrically arranged at both ends of the circuit board accommodating grooves for placing circuit boards. The fixing holes on the circuit board pass through the fixed shafts arranged on the placement blocks to prevent the circuit board from shaking. The placed circuit board realizes the automatic rotation of the spring pressure plate under the drive of the clamping device, thereby ensuring the smooth operation of the pallet and the stability of the circuit board during welding, which is convenient for promotion.
