[0031] The present application provides a method for making positioning holes of single- and double-sided panels, comprising installing a plurality of positioning components on the fixing seat so that the plurality of positioning components extend out of the fixing seat and form a positioning area on the fixing seat; stacking a plurality of single- and double-sided panels on the positioning area so that the plurality of positioning components respectively abut against the edges of the single- and double-sided panels to prevent the single- and double-sided panels from moving along the surface of the fixing seat; and drilling the plurality of single- and double-sided panels so that positioning holes are formed on the single- and double-sided panels.

[0032] In the above-mentioned method for making positioning holes of single and double panels, multiple positioning components are arranged along the edge of each single and double panel, and the multiple positioning components are all in contact with the edge of each single and double panel to prevent each single and double panel from moving along the surface of the fixing seat, so that the position stability of each single and double panel is high, and the drilling accuracy is improved, that is, the accuracy of the positioning holes formed by each single and double panel is improved. Moreover, multiple single and double panels are stacked on the fixing seat, so that multiple single and double panels can be drilled at the same time, which improves the drilling efficiency.

[0033] In order to better understand the technical solutions and beneficial effects of the present application, the present application is further described in detail below in conjunction with specific embodiments:

[0034] like Figure 1 As shown, a method for making positioning holes in a single or double-sided board according to an embodiment includes some or all of the following steps:

[0035] S100: Installing a plurality of positioning components on the fixing seat, so that the plurality of positioning components extend out of the fixing seat and form a positioning area on the fixing seat.

[0036] In this embodiment, multiple positioning components are installed on the fixed base at intervals, so that the multiple positioning components are fixed on the fixed base, and multiple fixing parts extend from the fixed base, so that the multiple positioning components form a positioning area on the fixed base, and the positioning area is adapted to the shape of the single or double-sided board, so that the multiple positioning components can position each single or double-sided board.

[0037] S300: stacking a plurality of single- and double-sided boards on the positioning area, so that the plurality of positioning components respectively abut against edges of the single- and double-sided boards to prevent the single- and double-sided boards from moving along the surface of the fixing seat.

[0038] In this embodiment, multiple single-double panels are stacked on the positioning area, that is, multiple single-double panels are stacked on a fixed seat, and multiple single-double panels are located in the positioning area, so that multiple positioning components are respectively abutted against the edges of each single-double panel, so that each single-double panel is limited to the positioning area, thereby avoiding the movement of each single-double panel along the surface of the fixed seat, thereby making the position stability of each single-double panel higher, and making the positioning holes formed by each single-double panel have higher accuracy.

[0039] S700: performing a drilling operation on the plurality of single-sided and double-sided boards to form positioning holes on each of the single-sided and double-sided boards.

[0040] In this embodiment, after positioning multiple single- and double-sided panels in the positioning area, drilling operations are performed on the multiple single- and double-sided panels to remove material from predetermined areas of each single- and double-sided panel, thereby forming positioning holes on each single- and double-sided panel. The positioning holes of each single- and double-sided panel are used for positioning in subsequent processing steps.

[0041] In the above-mentioned method for making positioning holes of single and double panels, multiple positioning components are arranged along the edge of each single and double panel, and the multiple positioning components are all in contact with the edge of each single and double panel to prevent each single and double panel from moving along the surface of the fixing seat, so that the position stability of each single and double panel is high, and the drilling accuracy is improved, that is, the accuracy of the positioning holes formed by each single and double panel is improved. Moreover, multiple single and double panels are stacked on the fixing seat, so that multiple single and double panels can be drilled at the same time, which improves the drilling efficiency.

[0042] In one embodiment, each edge of each single-double panel abuts against at least one positioning component to prevent each single-double panel from moving along the surface of the fixing seat, thereby ensuring the position stability of each single-double panel, so that the precision of the positioning holes of each single-double panel is high. Furthermore, the center of each edge of each single-double panel abuts against one positioning component to make each single-double panel evenly stressed, so that the position stability of each single-double panel is further enhanced, thereby improving the precision of the positioning holes of each single-double panel.

[0043] In one embodiment, the step of installing a plurality of the positioning components on the fixing seat so that the plurality of the positioning components extend out of the fixing seat and form a positioning area on the fixing seat includes: drilling the fixing seat so that the fixing seat forms a plurality of fixing holes; installing a plurality of positioning components in the plurality of fixing holes one by one so that the plurality of positioning components extend out of the fixing seat and form a positioning area on the fixing seat. In this embodiment, the fixing seat is firstly drilled by a CNC drill so that a plurality of fixing holes are formed on the fixing seat; then a plurality of positioning components are inserted into the plurality of fixing holes one by one so that the plurality of positioning components are fixed on the fixing seat, and at the same time, the plurality of positioning components extend out of the fixing seat, thereby forming a positioning area on the fixing seat.

[0044] Furthermore, each of the positioning components is interference fit with the corresponding fixing hole to improve the connection strength between each of the positioning components and the fixing parts, so that the position stability of each of the positioning components is higher, thereby making the positioning effect of each of the single- and double-sided panels better, thereby making the position stability of each of the single- and double-sided panels higher, thereby making the accuracy of the positioning holes of each of the single- and double-sided panels higher.

[0045] Furthermore, each of the positioning components is a pin, so that the dimensional accuracy of each of the positioning components is higher, and thus the positioning accuracy of the positioning components is higher, thereby improving the positioning effect of each of the positioning components, making the position stability of each single or double-sided board higher, and thus the accuracy of the positioning holes of each single or double-sided board higher.

[0046] In one embodiment, each positioning component is interference fit with the corresponding fixing hole, and after the step of drilling the fixing base to form a plurality of fixing holes in the fixing base, and before the step of installing the plurality of positioning components one by one in the plurality of fixing holes, the single- and double-panel panel positioning holes also include: heating the fixing base to expand the diameter of each fixing hole.

[0047] In the present embodiment, in order to improve the connection stability between each positioning component and the fixing seat, each positioning component and the corresponding fixing hole are interference fit, which makes it difficult for each positioning component to be installed in the corresponding fixing hole. Therefore, after the step of drilling the fixing seat to form a plurality of fixing holes in the fixing seat, and before the step of installing the plurality of positioning components in the plurality of fixing holes one by one, the fixing seat is heated to make the fixing seat expand due to heat expansion, so that the diameter of the fixing hole is expanded, and each positioning component is easier to be installed into the corresponding fixing hole, thereby improving the installation efficiency of each positioning component, and at the same time, the interference fit between each positioning component and the corresponding fixing hole can be larger, thereby making the connection stability between each positioning component and the fixing seat higher, thereby making the positioning effect of each positioning component more stable, thereby making the position stability of each single-double-panel panel higher, thereby making the accuracy of the positioning holes of each single-double-panel panel more stable.

[0048] In order to improve the position stability of each positioning component and thus improve the positioning accuracy of each positioning component, the interference between each positioning component and the corresponding fixing hole is relatively large. To this end, in another embodiment, each positioning component is installed in the corresponding fixing hole by knocking, so that each positioning component is smoothly installed in the corresponding fixing hole.

[0049] In one embodiment, the step of stacking the plurality of single-double panels on the positioning area includes: stacking a flexible pad on the positioning area; stacking the plurality of single-double panels on the flexible pad, so that the plurality of single-double panels are stacked on the positioning area through the flexible pad. In this embodiment, the flexible pad is a flexible structure, and a flexible pad is stacked between the single-double panels and the fixing seat, so that the bottom surface of the bottom single-double panel contacts the flexible pad, avoiding the bottom surface of the bottom single-double panel from contacting the fixing seat, thereby avoiding the problem of the fixing seat scratching the bottom single-double panel. In one embodiment, the flexible pad is a wood pulp pad.

[0050] In one embodiment, each of the single- and double-sided boards is located within the outer contour of the flexible pad, so that the flexible pad completely isolates the bottom single- and double-sided boards from the fixing base, thereby completely avoiding the problem of the fixing base scratching the bottom single- and double-sided boards.

[0051] In one embodiment, the fixing base is a bakelite board, so that the fixing base has high strength and heat resistance. In this embodiment, the strength of the fixing base makes it difficult to damage the fixing base when positioning the single or double panels, thereby increasing the service life of the fixing base. In addition, the fixing base has strong heat resistance, making it difficult to damage the fixing base after being heated, so that each positioning component can be installed on the fixing base by thermal installation, thereby reducing the difficulty of installing each positioning component, thereby increasing the installation efficiency of each positioning component.

[0052] In order to suppress the deformation of the positioning component and improve the position stability of each single-double panel, thereby improving the accuracy of the positioning holes of each single-double panel, in one embodiment, after the step of stacking multiple single-double panels on the positioning area so that the multiple positioning components respectively abut the edges of each single-double panel to avoid the single-double panel from moving along the surface of the fixing seat, and before the step of drilling the multiple single-double panels to form positioning holes on each single-double panel, the single-double panel positioning hole production method also includes: providing multiple positioning abutment components, wherein the multiple positioning abutment components are arranged along the circumference of each single-double panel, and the multiple positioning abutment components are arranged one-to-one with the multiple positioning components; each positioning abutment component is correspondingly abutted against the side of the corresponding positioning component away from each single-double panel, and each positioning abutment component is abutted against the edge of each single-double panel. In this embodiment, multiple positioning abutment components and multiple positioning components are arranged in one-to-one correspondence, and multiple positioning abutment components are all installed on a fixed seat, so that each positioning abutment component abuts against the side of the positioning component away from each single or double-sided panel, so as to suppress the deformation of the positioning component pushed by each single or double-sided panel, thereby improving the shape stability of each positioning component. At the same time, each positioning abutment component abuts against the edge of each single or double-sided panel to suppress the movement of each single or double-sided panel, so that the position stability of each single or double-sided panel is higher, thereby making the accuracy of the positioning holes formed by each single or double-sided panel higher.

[0053] Furthermore, the positioning and abutting components are provided with abutting grooves, and the parts of the positioning components facing away from the single- or double-sided boards are received in the abutting grooves of the corresponding positioning and abutting components, and the side of the positioning pins facing away from the single- or double-sided boards abuts against the groove wall of the abutting grooves of the corresponding positioning and abutting components, so that the positioning and abutting components limit the deformation of the corresponding positioning components, thereby improving the shape stability of the corresponding positioning components, thereby improving the positioning effect of the corresponding positioning components, and thereby improving the accuracy of the positioning holes of the single- or double-sided boards. Furthermore, the side of the positioning and abutting components adjacent to the single- or double-sided boards abuts against the edge of the corresponding single- or double-sided boards, so that the position stability of the single- or double-sided boards is higher, thereby making the accuracy of the positioning holes of the single- or double-sided boards higher.

[0054] Furthermore, each of the positioning and abutting components includes an abutting member and a fastener, and the abutting groove of each of the positioning and abutting components is provided on the corresponding abutting member, and the abutting member of each of the positioning and abutting components is provided with an avoidance hole, and the fixing seat is provided with a plurality of waist-shaped holes, and the fasteners of each of the positioning and abutting components are correspondingly penetrated through the corresponding avoidance hole and the corresponding waist-shaped hole, so that the abutting member of each of the positioning and abutting components can be adjustably connected to the fixing seat. In this embodiment, before a plurality of single-double panels are stacked on the fixing seat, there is a gap between each of the positioning and abutting components and the corresponding positioning components, so that each of the single-double panels will not rub against each of the positioning and abutting components when being stacked on the fixing seat, so that the resistance of each of the single-double panels stacked on the fixing seat is small, thereby improving the smoothness and efficiency of each of the single-double panels stacked on the fixing seat. After multiple single- and double-sided panels are stacked on a fixed seat, the abutment members of each positioning abutment assembly are moved so that the abutment members of each positioning abutment assembly abut against the corresponding positioning assembly and the edge of each single- and double-sided panel respectively, and then the abutment members of each positioning abutment assembly are fixed to the fixed seat by corresponding fasteners, so that each positioning abutment assembly suppresses the deformation of the corresponding positioning assembly, while improving the position stability of each single- and double-sided panel, thereby improving the accuracy of the positioning holes of each single- and double-sided panel.

[0055] Furthermore, each of the positioning and abutment components also includes a buffer component, and the buffer component of each of the positioning and abutment components is connected to the side of the corresponding abutment component adjacent to each single or double-sided board, so that the abutment component of each of the positioning and abutment components abuts against the edge of each single or double-sided board through the corresponding buffer component, so that each of the positioning and abutment components elastically abuts against each single or double-sided board, thereby reducing the wear of the edges of each single or double-sided board caused by each of the positioning and abutment components, so that the quality of each double-sided board is higher.

[0056] It can be understood that after each single-double panel is placed on the fixing seat, the vibration of the equipment will drive each single-double panel to vibrate, that is, make each single-double panel move up and down. In addition, when drilling holes in each single-double panel, when the drill bit contacts the topmost single-double panel, the drill bit will drive each single-double panel to vibrate. The vibration of each single-double panel will cause the position stability of each single-double panel to be poor, so that the accuracy of the positioning holes of each single-double panel is poor. In one embodiment, the positioning abutment assembly also includes a clamping member, which is connected to the upper side of the abutment member, and the clamping member abuts against the surface of the topmost single-double panel, so that the clamping member limits the up and down movement of each single-double panel, that is, the clamping member limits the vibration of each single-double panel, thereby ensuring the position stability of each single-double panel, thereby improving the drilling accuracy, and thereby making the positioning accuracy of each single-double panel higher.

[0057] like Figure 2 As shown, in one embodiment, the fixing seat 100 is provided with a receiving groove 1001, and the fixing hole 1003 is located on the groove wall of the receiving groove 1001, and the fixing hole 1003 is communicated with the receiving groove 1001. The positioning assembly 300 includes a reference member 310 and an adjusting member 330, the reference member 310 is passed through the receiving groove 1001, and a part of the reference member 310 is located in the fixing hole 1003 and is fixedly sleeved with the fixing seat 100. The adjusting member 330 includes a first abutting column 331, a second abutting column 333 and a third abutting column 335 connected in sequence, the second abutting column 333 protrudes from the first abutting column 331, and the third abutting column 335 protrudes from the second abutting column 333, so that the adjusting member 330 forms a step structure, and the second abutting column 333 and the third abutting column 335 are both telescopic in the receiving groove 1001. The first abutting column 331 defines a first threaded hole 3311, the second abutting column 333 defines a second threaded hole 3331, and the third abutting column 335 defines a third threaded hole 3351. The first threaded hole 3311, the second threaded hole 3331 and the third threaded hole 3351 are connected in sequence, so that the first threaded hole 3311, the second threaded hole 3331 and the third threaded hole 3351 together form a threaded channel 3301, and the end of the reference member 310 away from the fixing hole 1003 is located in the threaded channel 3301 and is threadedly connected to the adjusting member 330.

[0058] In this embodiment, the fixing seat 100 is provided with a connected receiving groove 1001 and a fixing hole 1003, and the fixing hole 1003 is located on the bottom wall of the receiving groove 1001, that is, the fixing hole 1003 is located on the groove wall adjacent to the opening of the receiving groove 1001, and the reference part 310 of the positioning component 300 is inserted into the receiving groove 1001, and one end of the reference part 310 of the positioning component 300 is inserted into the fixing hole 1003 and fixedly connected with the fixing seat 100, so that the reference part 310 of the positioning component 300 is fixed on the fixing seat 100, and the part of the reference part 310 away from the positioning hole 1003 is provided with an external thread. The adjusting member 330 includes a first abutting column 331, a second abutting column 333 and a third abutting column 335, which are fixedly connected in sequence and coaxially fixed, the second abutting column 333 protrudes from the first abutting column 331, and the third abutting column 335 protrudes from the second abutting column 333, so that the adjusting member 330 forms a step structure. The first abutting column 331, the second abutting column 333 and the third abutting column 335 are respectively provided with a first threaded hole 3311, a second threaded hole 3331 and a third threaded hole 3351, which together form a threaded channel 3301, and the threaded channel 3301 is located at the center of the first abutting column 331, the second abutting column 333 and the third abutting column 335. The portion of the reference member 310 that faces away from the fixing hole 1003 is located in the threaded channel 3301 and is threadedly connected to the adjusting member 330, so that the adjusting member 330 can be adjustably connected to the reference member 310, that is, the adjusting member 330 can move downward along the reference member 310, so that the first abutment column 331, the second abutment column 333 or the third abutment column 335 are used to abut the single or double-sided board 500, thereby allowing the adjusting member 330 to adapt to single or double-sided boards 500 of different sizes, thereby improving the adaptability of the positioning assembly 300.

[0059] It is understandable that when drilling a single or double-sided board 500, once the drill bit drops too much, the fixing base 100 will be damaged. In order to avoid the fixing base 100 being drilled by mistake, Figure 3 As shown, in one embodiment, the fixing seat 100 is provided with an air avoidance groove 1005, and the air avoidance groove 1005 is arranged corresponding to the positioning hole of the single-double panel 500. In this embodiment, when the drill bit drops excessively, the drill bit enters the air avoidance groove 1005, thereby avoiding the drill bit from accidentally damaging the fixing seat 100, thereby increasing the service life of the fixing seat 100. In addition, when drilling a single-double panel 500, the debris of the single-double panel 500 partially enters the air avoidance groove 1005, reducing the obstruction of the debris to the drill bit, suppressing the situation where the drill bit is stuck, that is, improving the smoothness of the drill bit drilling, thereby improving the accuracy of the positioning holes of each single-double panel 500, and at the same time increasing the service life of the drill bit.

[0060] When the debris fills up the air-avoiding groove 1005, the debris on the single-sided or double-sided board 500 cannot continue to enter the air-avoiding groove 1005, which will affect the smoothness of the drill bit drilling. In addition, since the size of the air-avoiding groove 1005 is small, the debris in the air-avoiding groove 1005 is difficult to clean. Figure 3 As shown, in one embodiment, the fixing seat 100 is further provided with a chip removal channel 1007, one end of which is connected to the air avoidance groove 1005, and the other end of which extends to the outside of the fixing seat 100. In this embodiment, the chips of the single- or double-sided board 500 enter the air avoidance groove 1005 and then slide down along the chip removal channel 1007 to the outside of the fixing seat 100, thereby preventing the chips from being blocked in the air avoidance groove 1005, and thereby allowing the chips from the single- or double-sided board 500 to continue to enter the air avoidance groove 1005, thereby reducing the obstruction of the chips to the drill bit and suppressing the drill bit from getting stuck, that is, improving the smoothness of the drill bit drilling, thereby improving the accuracy of the positioning holes of each single- or double-sided board 500, and at the same time improving the service life of the drill bit.

[0061] like Figure 3 As shown, further, the chip removal channel 1007 includes an inclined hole 1007a and a chip pushing hole 1007b that are connected, the inclined hole 1007a is inclinedly opened on the fixed seat 100, one end of the inclined hole 1007a is connected to the air-avoiding groove 1005, and the other end of the inclined hole 1007a is connected to the chip pushing hole 1007b, and the chip pushing hole 1007b extends to the outer wall of the fixed seat 100. The fixed seat 100 includes a fixed plate 110 and a pusher 130, the receiving groove 1001, the fixed hole 1003, the inclined hole 1007a, the chip pushing hole 1007b and the air-avoiding groove 1005 are all opened on the fixed plate 110, a plurality of single and double panels 500 are placed on the fixed plate 110, the pusher 130 is arranged in the chip pushing hole 1007b, the fixed end of the pusher 130 is fixedly connected to the fixed plate 110, and the pusher end of the pusher 130 is telescopic in the chip pushing hole 1007b. In this embodiment, after the debris of each single- and double-sided board 500 falls into the air-avoiding groove 1005, the corresponding debris slides along the inclined hole 1007a into the chip-pushing hole 1007b, and the pushing end of the pushing member 130 pushes the corresponding debris to move, so as to push the corresponding debris out of the fixed plate 110, thereby cleaning the air-avoiding groove 1005 and avoiding the problem of chip blockage in the air-avoiding groove 1005. It can be understood that the pushing member 130 can be a cylinder, a hydraulic cylinder, a pushing motor or other existing pushing members 130.

[0062] In order to avoid the problem that the positioning accuracy of the fixed plate 110 is affected by wear, or even the entire fixed plate 110 is scrapped, the fixed plate 110 further includes a base 111 and a support seat 113. The base 111 and the support seat 113 are detachably connected. The receiving groove 1001, the fixing hole 1003, the inclined hole 1007a and the chip pushing hole 1007b are all opened on the base 111. The base 111 is also provided with an installation groove 1111. The support seat 113 is installed in the installation groove 1111. The air avoidance groove 1005 is opened on the support seat 113.
