[0028] By adopting the above technical solution,

[0029] Working principle and usage process of the utility model: When in use, during the operation of the equipment, the driving motor 72 in the tape collecting device 7 fixed on one side of the working table of the drilling machine body drives the second paper tape and aluminum tape reel 71 to rotate, causing the paper tape and aluminum tape to perform winding actions, thereby moving the paper tape and aluminum tape by a set specified length; the paper tape and aluminum tape are installed on the surface of the second pre-tightening and guiding roller group 73, and the aluminum tape passes through the inside of the second pressing mechanism 74 and the second pre-tightening mechanism 75;

[0030] The first paper tape and aluminum tape reel 11 in the tape releasing device 1 fixed on the other side of the working table of the drilling machine body is driven to rotate synchronously by the pulling force of the winding actions of the paper tape and aluminum tape; and the paper tape and aluminum tape are installed on the surface of the first pre-tightening and guiding roller group 12, and the aluminum tape passes through the inside of the counting mechanism 14, the first pressing mechanism 15 and the first pre-tightening mechanism 16; the specified length of the movement of the paper tape and aluminum tape is read by the encoder in the counting mechanism 14 and transmitted to the control system;

[0031] After the paper tape and aluminum tape move to the set specified length, the driving motor 72 that drives the second paper tape and aluminum tape reel 71 to rotate stops rotating, the cylinder in the second pressing mechanism 74 moves to press the aluminum tape body 5, and the cylinder in the second pre-tightening mechanism 75 moves to pre-tighten the aluminum tape body 5 to prevent the middle of the aluminum tape body 5 from sagging and rubbing against the PCB circuit board 8, scratching the surface of the PCB circuit board 8, and the sensor 13 detects the paper tape and aluminum tape in real time and provides an alarm message to the control system when there is damage or material shortage;

[0032] After moving the paper tape and aluminum tape to the set specified length by the pulling force of the winding actions and performing pressing and pre-tightening actions on the aluminum tape body 5, the handling robot or manipulator transports the PCB circuit board 8 to the designated position on the working table of the drilling machine. At this time, the PCB circuit board 8 is located between the paper tape body 9 and the aluminum tape body 5 and has gaps with both the paper tape body 9 and the aluminum tape body 5, and the handling robot or manipulator places the PCB circuit board 8 on the working table of the drilling machine;

[0033] The driving cylinders 22 in the first aluminum tape up and down moving mechanism 2 and the second aluminum tape up and down moving mechanism 6 drive the slide rail assembly 21, the aluminum tape guiding roller 23, and the connecting plate 24, and drive the aluminum tape body 5 to move downward together and fit on the upper surface of the PCB circuit board 8;

[0034] The pressing cylinder of the tongue moving mechanism 31 in the pressing and tensioning device 3 fixed on the body surface of the drilling machine drives the tongue main body 4 to press the paper tape body 9, the PCB circuit board 8, and the aluminum tape body 5 together and tightly fit them on the working table of the drilling machine. At this time, the drilling machine starts drilling operations; when the drilling position interferes with the position of the tongue main body 4, the tongue moving mechanism 34 in the pressing and tensioning device 3 drives the mounting plate 32 and the tongue moving slide rail assembly 33 to move to a safe position through the connecting bracket 35 to avoid interference with the drilling position;

[0035] After the drilling process is completed, the pressing cylinder of the tongue pressing mechanism 31 drives the tongue pressing body 4 to rise, and the driving cylinders 22 in the first aluminum strip vertical movement mechanism 2 and the second aluminum strip vertical movement mechanism 6 drive the slide rail assembly 21, the aluminum strip guiding rollers 23, and the connecting plate 24 to drive the aluminum strip body 5 to move upward together, so that the aluminum strip body 5 is separated from the upper surface of the PCB circuit board 8. At the same time, the handling robot or manipulator transports the PCB circuit board 8 to the discharging platform; when the processed PCB circuit board 8 leaves the drilling machine workbench, the equipment restarts a new work process to perform a new drilling process.
