Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1 and 2, the present invention provides a small-distance water-absorbing roller structure for PCB equipment, including: a plurality of cotton 1, locate to absorbing water that set up side by side absorb water cotton 1 side with absorb water cotton 1 parallel line rumble 2 and drive absorb water cotton 1 and line rumble 2 pivoted drive mechanism. Each pair of the absorbent cotton 1 comprises an upper absorbent cotton 1 and a lower absorbent cotton 1, and the absorbent cotton 1 is used for absorbing the water on the surface of the PCB. The front side and the rear side of cotton 1 that absorb water all are equipped with capable rumble 2, and the rumble 2 of going is used for transmitting the PCB board. The partial line rumbles 2 are arranged from top to bottom, the PCB board passes through the two line rumbles 2 arranged from top to bottom, and the line rumbles 2 rotate to drive the PCB board to move. When the PCB passes through the water absorption cotton 1 arranged up and down, the water absorption cotton 1 is contacted with the surface of the PCB to absorb the water on the surface of the PCB.

The transmission mechanism includes: the transmission shaft 3, the drive the transmission shaft 3 pivoted transmission shaft drive assembly, locate drive gear one 4 on the transmission shaft 3, with drive gear one 4 meshed driven gear one 5, locate drive gear two 6 on the transmission shaft 3, and with drive gear two 6 meshed driven gear two 7. The line rumble 2 with driven gear 5 is connected, the cotton 1 that absorbs water with driven gear two 6 are connected, the diameter of the cotton 1 that absorbs water is far greater than the diameter of line rumble 2 and the rumble 2 that goes is close or unanimous with the transport speed of the cotton 1 that absorbs water.
