Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of PCB board overturning structure, and particularly relates to an automatic overturning device for a PCB board. BACKGROUND

[0002] In the double-sided processing (such as welding, patching, detection) process of a PCB board, an automatic overturning device for a PCB board is often used to accurately control the overturning angle precision, clamping stability and action smoothness, so as to avoid the following problems: the alignment of the subsequent process is invalid due to the deviation of the overturning angle, the PCB board is damaged or deformed due to improper clamping force, or the components on the board are detached due to action impact, thereby affecting the processing yield, production process connection efficiency and product reliability of the PCB board.

[0003] The existing automatic overturning device for a PCB board has obvious defects in processing continuity and operation efficiency. In the overturning process, the worker needs to manually clean the welding slag on the surface of the PCB board, and after the double-sided welding processing is completed, the static electricity needs to be removed through a separate static electricity removal process. The overall steps are complicated and inefficient. When manually cleaning the welding slag, the worker needs to wipe the surface of the PCB board one by one after the overturning device is stopped, which not only interrupts the continuous process of overturning and welding, but also easily scratches the PCB board circuit or leaves residual welding slag debris due to improper operation force control, thereby affecting the subsequent welding quality. The separate static electricity removal process needs to transfer the PCB board to a special device, which not only increases the handling time and risk of collision, but also prolongs the overall processing cycle due to the fragmentation of the process.

[0058] At this time, the back of the PCB board faces upward, the staff welds the back, and after the back welding is completed, the driving member 25 is started again, the hydraulic rod 251 continues to drive the rotating cam 254 to rotate, drives the elastic clamping piece 13 and the PCB board to turn over 180° again; in the turning over process, the anti-static cleaning brush 211 is attached to the back of the PCB board to passively clean under the action of the first spring 213, and at the same time, the driven spiral shaft 236 continues to rotate, adjusts the air pressure of the air chamber 234 on the other side through the right magnetic connecting block 239 and the piston rod 235, and repeats the gas circulation, blowing action, and auxiliary cleaning of the back waste.

[0059] After the back welding is completed, the default processing is complete, the driving member 25 drives the transmission member 26 to rotate reversely, drives the driven spiral shaft 236 to reset, and when the driven spiral shaft 236 resets, the fixed gear 241 on the surface thereof rotates synchronously, the first shifting block 242 on the fixed gear 241 shifts the second shifting block 247 of the fixed locking member 24, the second shifting block 247 drives the connecting sleeve 244 to slide along the fixed horizontal rod 243 and compresses the second spring 245 through the plug-in shifting block 246, the plug-in shifting block 246 is separated from the fixed locking of the first conductive extension rod 222, and the first conductive extension rod 222 and the second conductive extension rod 223 fall along the connecting support 221 under the action of gravity, drive the metal conductive plate 225 to attach to the surface of the PCB board, and the metal grounding plate 224 to attach to the grounding bottom plate 11, and realize the PCB board grounding and static elimination.
