[0030] Specifically, the front end of at least two of the left upper side, the middle upper side, and the right upper side of the workbench 201 is provided with a PCB blocking positioning rod 9 that can be lifted up and down, and the PCB blocking positioning rod 9 can be driven upward by the lifting mechanism to block the forward movement of the PCB 3, so as to position the front edge of the PCB 3; the plurality of inner conveying belts 401 and the plurality of outer conveying belts 401 are respectively driven by different powers, so that the plurality of inner conveying belts 401 and the plurality of outer conveying belts 401 have different left and right moving distances; the left upper side and the right upper side of the workbench 201 are respectively driven by different powers, so that the left upper side and the right upper side of the workbench 201 can move left and right respectively. Action: The blocking positioning rod 9 is driven up and down by the lifting mechanism, so that in step (3) (i.e. the third step) of the above scheme: After the position adjustment of the workbench and the conveying belt, three or two blocking positioning rods 9 are driven upward by the lifting mechanism. And in step (4) (i.e. the fourth step) of the above scheme: When the incoming PCB is moved to above the left upper side, the middle upper side, and the right upper side of the workbench, the blocking positioning rod 9 will position the front edge of the incoming PCB, and after positioning, the suction hole on the workbench fixes the PCB to prevent displacement of the PCB, and then the blocking positioning rod 9 is driven downward by the lifting mechanism. By setting in this way, the PCB to be drilled can be blocked and positioned at the predetermined drilling station. In addition, the reason why the conveying belts 401 have different left and right moving distances is to avoid the middle position being too empty due to the large outward movement of all conveying belts 401, thereby avoiding insufficient support of the middle of the PCB. The reason why the left upper side and the right upper side of the workbench 201 move left and right respectively is that when the drilling equipment determines through the PCB shooting result of the CCD positioning device that there is a lack of paper tape 203 between the workbench on one side and the edge of the PCB 3 on one side (for example, the paper tape below the position to be drilled on the PCB has been punched, or the paper tape has not been moved to the position), the workbench on the side moves left and right, so that the paper tape 203 on the workbench on the side moves to the lower side of the PCB 3, avoiding damage to the workbench, and achieving effective use of the paper tape.

[0031] Specifically, the front and rear ends of the workbench 201 on the left upper side are respectively provided with a paper tape collecting mechanism 204 and a paper tape releasing mechanism 205, the front and rear ends of the workbench 201 on the right upper side are respectively provided with a paper tape collecting mechanism 204 and a paper tape releasing mechanism 205, and the paper tape collecting mechanism 204 and the paper tape releasing mechanism 205 can cooperate to realize the forward movement of the paper tape 203 on the top surface of the workbench 201; the workbench 201 is provided with a light source 207 that can penetrate the PCB 3 upward, and the light source 207 can cooperate with the CCD positioning device 7 to read the position coordinates of the included angle of the PCB 3. Effect: The paper tape is a consumable product, and through the cooperation of the paper tape collecting mechanism 204 and the paper tape releasing mechanism 205, the paper tape can be automatically moved forward on the workbench 201 on the left upper side and the right upper side, and the paper tape can be automatically replaced, so that each position of the paper tape can be reasonably utilized, and the paper tape winding action can be driven by a motor through the paper tape collecting mechanism. By providing the light source 207 that penetrates the PCB 3 upward, the problem of reflection caused by the downward illumination of the light source to the PCB can be avoided, and interference can be reduced. By reading the position coordinates of the included angle of the PCB 3 (generally, the included angle is a right angle of a rectangular PCB, and the CCD camera can capture the reference position coordinates of the PCB), the distances of the two sides of the included angle can be read, so that the position coordinates of the PCB can be more effectively determined.

[0032] Specifically, the front ends of the workbenches 201 on the left upper side and the right upper side are respectively provided with an encoder 206, and an elastic pressing plate 214 is arranged above the encoder 206 to make the paper tape 203 tightly contact with the transmission wheel of the encoder 206, so as to prevent the encoder 206 from causing data error due to the slipping of the paper tape 203 and the transmission wheel of the encoder 206, and the encoder 206 can be used to record the releasing length of the paper tape 203; the front end of the workbench 201 on the left upper side or the right upper side is provided with a light source 207, and the rear end of the workbench 201 on the left upper side or the right upper side is respectively provided with a PCB plate entering center guide plate 208, and the PCB plate entering center guide plate 208 can make the PCB 3 enter the workbench 201 in the center. Effect: The releasing length of the paper tape (preferably an aluminum paper tape) is recorded by the encoder. In fact, the light source 207 can be arranged at any position of the workbench 201 on the left upper side or the right upper side, and the number can be one or a row, but since one light source can capture one position coordinate of the PCB and infer other position coordinates, it is not necessary to set a large number of light sources. The two PCB plate entering center guide plates 208 are arranged to facilitate the center entry of the PCB.

Effect: The support of the gantry support 102 facilitates the rapid reciprocating motion of the X-axis sliding block 5 in the gantry 101. Because the tools 14 in the tool magazine 11 are too dense, the drilling spindle is not convenient to directly take the tool 14, at this time, the moving end of the mechanical hand 10 with small volume needs to grab the tool 14 in the tool magazine 11 downward and reset upward, and then place the tool 14 on the transfer disc 12, then the drilling assembly 8 grabs the tool 14 on the transfer disc 12 to the detection table 13 for detection of tool length, diameter, etc. (the bottom of the tool is a sharp end matched with a paper tape, and the upper part is a cylindrical end matched with a PCB board), if the tool 14 meets the requirements, the tool 14 is used to process the target hole 301 and the foolproof hole 302 of the PCB board 3.
