Positioning and clamping apparatus for cell electrode plate groups, lead bridges, and lead heads of lead-acid battery

A positioning and clamping apparatus for cell electrode plate groups, lead bridges, and lead heads of a lead-acid battery, comprising:

• a hoisting unit comprising a support plate, two piston members, two first actuators, two hoisting plates, and an interconnection plate wherein the piston members are disposed on two sides of the support plate respectively, the first actuators are disposed on the sides of the support plate respectively, the piston member is adjacent to the first actuator of the same side, the hoisting plate is disposed on tops of both the piston member and the first actuator of the same side, each of the first actuators include a first piston threadedly secured to the hoisting plate, the interconnection plate is disposed across the hoisting plates, and the first pistons are configured to threadedly raise or lower the hoisting plates which in turn raise or lower the interconnection plate;
• a transporting unit comprising a second actuator, two movement rods, and a transporting plate wherein the second actuator and the movement rods are disposed on the support plate, the second actuator includes two parallel second pistons secured to the transporting plate, the movement rods are disposed at two sides of the second actuator respectively, first ends of the movement rods are secured to the transporting plate, and the transporting plate is disposed at a first end of the support plate so that the second pistons are configured to move the movement rods and the transporting plate forward or rearward;
• and
• a micro adjustment positioning unit comprising a limiting plate, two follower plates, two sliding members, a third actuator, and a positioning plate wherein the limiting plate is disposed on a first end of the transporting plate opposing the support plate, the follower plate is disposed under the hoisting plates and secured to the limiting plate, each of the sliding members are disposed between the hoisting plate and the follower plate of the same side, the third actuator is secured to the interconnection plate and includes a third piston passing through the interconnection plate and threadedly secured to the positioning plate, and the positioning plate is secured to the follower plate so that the third piston is configured to move the positioning plate forward or rearward and in turn the positioning plate is configured to move the follower rods and the limiting plate forward or rearward.
