The specific working principle is as follows:

the equipment is a link in a production line, a previous process is carried, an upper carrier drives a PCB to enter from the right end of a graph 1, the right end of a main conveying line moves to a specified position, a first jacking mechanism acts to jack the PCB for a certain distance and separate from the upper carrier, then a rotating motor in a PCB overturning assembly acts to drive the PCB to overturn by nearly 180 degrees, the PCB is sucked through a sucker, after the sucking operation is finished, the rotating motor rotates reversely to drive the PCB to overturn to an initial position, and at the moment, the upper and lower overturning of the PCB is finished. Next, the manipulator device operates according to a program, sucks and takes the carrier down to a specified position on the left-end main conveying line on the input line of the lower carrier, and the second jacking mechanism operates to move the carrier up by a specific section and enable a positioning pin to penetrate through a specified hole of the lower carrier, so that positioning is realized and position data are sent; the manipulator device reaches the upper part of the PCB overturning assembly according to program action, sucks the PCB through a sucking disc of the manipulator, drives the PCB to move to the upper part of the lower carrier together, and places the PCB on the lower carrier; next, the lower carrier drives the PCB to move on the left-end main conveying line, after the PCB reaches a designated position, the third jacking mechanism acts to move the lower carrier and the PCB upwards for a certain distance, and the PCB is fixed under the action of the pressing plate to prevent the PCB from moving; then, the gummed paper separating device acts to cut out gummed paper with a specified length, the rotary labeling device adsorbs the gummed paper with a fixed length, the gummed paper is driven to be positioned above the lower carrier through an XYZ motion module, the gummed paper is adhered to the specified positions of the PCB and the lower carrier, and the adhesion of the gummed paper at four positions is sequentially completed; the specific work flow of the gummed paper separating device is as follows: the adhesive paper is manually loaded, a small section of adhesive paper is pulled out initially, the adhesive paper is adsorbed on the middle hollow suction plate, and the adhesive paper is enabled to protrude 4-5mm from the suction plate due to the fact that the suction plate is arranged above the adhesive paper, so that the adhesive paper is convenient to clamp; the rotating pressure head rotates 90 degrees, the gummed paper is pressed on the gummed paper separating platform under the action of the rotating pressing-down cylinder, the straight-pushing cylinder moves forward for a specified distance, the linear guide rail moves to drive parts on the straight-pushing cylinder to move forward for specified displacement, further the gummed paper and gummed paper separating platform is driven, the rotating pressure head moves forward to pull out the gummed paper by a specified length, the side-pushing cylinder drives the scissors to move to a gummed paper pre-shearing position, the scissors are driven to do shearing action under the action of the spiral cylinder to realize gummed paper shearing, the original path of the rotating pressure head returns to rotate 90 degrees, the gummed paper with the specified length to enter the next process, and the process is repeated.

The specific working principle of the rotary labeling device is as follows: under the control of a program, the stepping motor acts to send out a designated pulse to drive the driving gear and the driven gear to be meshed for outputting power, so that the hollow rotating shaft is driven to rotate, and the hollow rotating shaft clamps the driven gear through the locking head; at the moment, the lower part of the rotary air joint rotates along with the hollow rotating shaft, and the upper joint part does not move; because the hollow rotating shaft is hollow, the pressurized gas flows into the gas path through the hollow part of the hollow rotating shaft to provide negative pressure for the vacuum suction head; when the device is close to the upper part of a sticker, the sliding guide sleeve is driven to move downwards through external power, so that the vacuum suction head is close to the sticker, the sticker is sucked up through the vacuum action, then the sliding guide sleeve moves upwards, then the sticker is rotated to the upper part of a PCB (printed circuit board) through an XYZ (X-Y) module, and after the action of rotating the hollow shaft at a certain angle is completed, the sticker continues to move downwards, and the sticker is pasted to a designated position; the operation is circulated for four times to complete the pasting of one PCB.

After all the gummed papers are pasted, the gummed papers confirm that the camera takes a picture, whether the PCB is pasted according to the rule is checked, if the pasting is not finished, the PCB is continuously pasted, and if the automatic pasting cannot solve the problem, an alarm is given (the probability is extremely low); after the action of pasting the gummed paper is finished, the downloading tool drives the PCB to move leftwards; at the moment, the left end main conveying line is provided with a blocking mechanism, and the blocking mechanism blocks the movement of the lower tool under the driving action of the air cylinder, mainly aiming at ensuring the beat operation of the whole assembly line.

Further, an upper loader is moved to the upper loader output line by the robot device. Thereby ensuring the loading tool and the unloading tool to be recycled.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
