[0058] In the attached Figure 2 In the figure, each bin is replaced by a block graphic. As for the specific structure of each bin, it can be implemented according to the following scheme.

[0059] In some specific embodiments of the present invention, the copper plate blank bin 160 and the cover plate blank bin 170 can include a lifting platform, on which the blanks are stacked up and down, and the lifting platform is driven to lift and lower by a screw rod or a chain, so that the plate moving mechanism 130 can take materials at the same position to cope with the situation where the blanks are gradually reduced.

[0060] In some specific embodiments of the present invention, the copper plate waste bin and the cover plate waste bin may include a hopper, and the plate shifting mechanism 130 directly puts the waste into the hopper, and the waste falls and is stacked up and down under the action of gravity, thereby reducing manufacturing costs.

[0061] For the substrate blank warehouse 150 and the substrate finished product warehouse, in some specific embodiments of the present invention, the substrate blank warehouse 150 and the substrate finished product warehouse can include a conveyor belt, which is conducive to realizing automatic feeding, automatic unloading and automatic transfer, reducing online inventory and reducing manufacturing costs.

[0062] In some specific embodiments of the present invention, the substrate blank warehouse 150 and the substrate finished product warehouse may include a lifting platform and a pad laying structure, and adjacent substrates are separated by pads to avoid friction between the substrates.

[0063] In some specific embodiments of the present invention, the substrate blank warehouse 150 and the substrate finished product warehouse can be arranged adjacent to each other, so that the pad can be shared. That is, the pad of the substrate blank warehouse 150 is used to separate the substrates in the substrate finished product warehouse to meet the needs of bulk transfer of substrates and reduce the occupied space.

[0064] Reference Figure 2 , Figure 3 and Figure 4 As for the plate moving mechanism 130, the plate moving mechanism 130 is located on one side of the plate storage mechanism 120 along the second direction. The plate moving mechanism 130 includes a first translation assembly 180 that moves along the first direction, and a second translation assembly 190 that is arranged on the first translation assembly 180.

The first lifting assembly 200 includes a lifting frame, and the lifting frame is provided with a plurality of suction plate discs 210. The plurality of suction plate discs 210 are used to stack the substrate blanks, copper plate blanks and cover plate blanks up and down on the workbench of the circuit board drilling machine 100. Adjacent substrate blanks are separated by the copper plate blanks, and the cover plate blanks are placed on the top layer.

[0065] In some specific embodiments of the present invention, the first translation assembly 180 may include a first guide rail 320 and a first translation seat 330 .

[0069] Reference Figure 3 , Figure 4 and Figure 5 As for the pasting mechanism 140, the pasting mechanism 140 is arranged on the lifting frame, and includes two bonding components. The two bonding components are arranged along the first direction. The two bonding components are used to bond two opposite edges of the cover plate blank to the workbench to prevent the rotation force of the tool during the drilling process from driving the cover plate, copper plate and substrate to move up and down, changing the shape of the drilled hole and affecting the processing quality.

[0070] In some specific embodiments of the present invention, the bonding assembly may include a glue-releasing wheel 220, a glue-collecting wheel 230, and a limiting rail 240 disposed between the glue-releasing wheel 220 and the glue-collecting wheel 230. The limiting rail 240 accommodates the adhesive tape released by the glue-releasing wheel 220 and moves toward the adhesive tape-collecting wheel 230. The limiting rail 240 is provided with a socket 250 that passes through from top to bottom. The socket 250 accommodates a pressing block 260. The pressing block 260 cooperates with the socket 250 to cut the adhesive tape. The pressing block 260 is provided with a soft pad for contacting the adhesive tape. The soft pad is used to make the adhesive tape close to the edge of the cover blank and the workbench.

[0071] The cushion has a plate-like shape, which is easy to understand and is not shown in the figure.

[0072] The present invention sets a plate storage mechanism 120 so that the plate storage mechanism 120 includes a loading plate storage area and a unloading plate storage area, and the loading plate storage area and the unloading plate storage area are arranged along a first direction. The loading plate storage area includes a substrate blank bin 150, a copper plate blank bin 160 and a cover plate blank bin 170, and the unloading plate storage area includes a substrate finished product bin, a copper plate waste bin and a cover plate waste bin. Therefore, it can be arranged on the front side of the drilling machine 100 and along the left and right directions of the drilling machine 100, which reasonably utilizes the space and shortens the plate picking and placing stroke, which is conducive to realizing the miniaturization of the automatic loading device 110.

[0073] The present invention can absorb various types of plates by setting up the plate moving mechanism 130, realize the movement, placement and stacking of the plates, and then stack multiple substrates together and separate them with copper plates, so as to facilitate drilling and processing multiple substrates at the same time, thereby improving processing efficiency.

[0074] The present invention sets a plate moving mechanism 130, so that the plate moving mechanism 130 includes a first translation assembly 180 that moves along a first direction, and a second translation assembly 190 arranged on the first translation assembly 180. The second translation assembly 190 can translate along a second direction. The second translation assembly 190 is provided with a first lifting assembly 200. The first lifting assembly 200 includes a lifting frame. The lifting frame is provided with a plurality of suction plate discs 210. The plurality of suction plate discs 210 are used to move the substrate blank. Therefore, the lifting height of the plate moving process can be reduced, the occupation of the internal space of the drilling machine 100 can be reduced, interference with the tool or main head of the drilling machine 100 can be avoided, and the drilling process will not be affected.

[0075] The present invention sets a bonding mechanism, which includes two bonding components, and the two bonding components are arranged along a first direction. The two bonding components are used to bond two opposite edges of the cover plate blank to the workbench. Therefore, the cover plate can be fixed on the workbench by tape, so as to avoid the cover plate, copper plate and substrate being lifted up by the force of the tool during drilling, thereby avoiding affecting the processing quality.

[0076] The present invention sets a bonding component, which includes a rubber release wheel 220, a rubber collection wheel 230, and a limiting rail 240 arranged between the rubber release wheel 220 and the rubber collection wheel 230. The limiting rail 240 accommodates the tape released by the rubber release wheel 220 to move toward the rubber collection wheel 230. The limiting rail 240 is provided with a socket 250 that passes through from top to bottom. The socket 250 accommodates a pressing block 260. The pressing block 260 cooperates with the socket 250 to cut the tape. The pressing block 260 is provided with a soft pad for contacting the tape. The soft pad is used to make the tape close to the edge of the cover blank and the workbench. Therefore, the tape can be automatically cut and pressed against the workbench and the cover, eliminating manual bonding, improving the feeding efficiency, and realizing the automation of feeding, thereby improving the feeding efficiency and helping to improve the processing efficiency of the substrate.

[0077] At the same time, the soft pad can also make up for the height difference between the cover plate and the workbench, so that the tape is firmly bonded to the cover plate and the workbench at the same time.

[0078] In some specific embodiments of the present invention, the pressing block 260 and the socket 250 can cut the tape, or the tape can be pre-cut after being fed, and the pressing block 260 only presses the tape against the workbench and the cover plate. At the same time, the difficulty of pasting is reduced by utilizing the characteristics that the tapes have few connections and are easy to disconnect, and there is no need to consider the wear between the pressing block 260 and the socket 250, thereby ensuring the bonding quality.

[0079] Reference Figure 6 In some specific embodiments of the present invention, the bonding component can be configured with two glue-releasing wheels 220, and a first clamping roller group 270 for compounding the tapes of the two glue-releasing wheels 220 is arranged between the glue-releasing wheels 220 and the limiting rail 240. The first clamping roller group 270 includes an upper fixed roller 280 and a lower compounding roller 290. The lower compounding roller 290 can be heated, and the lower compounding roller 290 can rise to cooperate with the upper fixed roller 280 to clamp the two tapes and heat-seal the two tapes together. A second clamping roller group 310 for driving the tape to move is arranged between the glue-collecting wheel 230 and the limiting rail 240.

[0080] It is easy to understand that the present embodiment uses two rubber release wheels 220, so that the length of the tape can be extended, and there is no need to re-thread the tape on the limiting rail 240, which shortens the time for replacing the tape and is conducive to maintaining the tension of the tape.

[0081] In some specific embodiments of the present invention, the radial outer surface of the lower composite roller 290 may be provided with a recess, and the recess is provided with a heating column 300, which protrudes out of the recess. The heating column 300 cooperates with the upper fixed roller 280 to composite the two tapes together.

[0082] It is easy to understand that during the rotation of the lower composite roller 290, the heating column 300 contacts the adhesive tape and squeezes the adhesive tape with the upper fixed roller 280, so that the two adhesive tapes are heat-sealed together, and the heating area is strictly controlled to avoid the adhesive tape from breaking.

[0083] In some specific embodiments of the present invention, the heating column 300 can be electrically heated, and the conduction method can be through mutually rotating conductive rings, which overcomes the problem of difficult installation of conductive wires.

[0084] In some specific embodiments of the present invention, the two rubber releasing wheels 220 may be disposed on the side of the rubber collecting wheel 230 close to the plate storage mechanism 120 along the first direction, and the two rubber releasing wheels 220 are arranged along the second direction to facilitate manual operation.

[0085] Reference Figure 4 , Figure 5 and Figure 6 In some specific embodiments of the present invention, the second translation seat 350 can be provided with a pair of first scraping hooks 360, and the first scraping hooks 360 can rotate around the second direction. The first scraping hooks 360 have a first position and a second position. When the first scraping hooks 360 are in the first position, the second translation seat 350 moves, and the first scraping hooks 360 scrape off the tape on the cover plate and the workbench. When the first scraping hooks 360 are in the second position, the second translation seat 350 moves, and the first scraping hooks 360 are away from the tape on the cover plate and the workbench.

[0086] It is easy to understand that after the drilling is completed, the suction plate 210 can be made to directly suck up the cover plate to separate the tape from the cover plate, but it will require higher strength. Moreover, after the tape is separated from the cover plate, the tape may still be adhered to the workbench, and the tape contacts the copper plate or the substrate. The tape will pull the substrate, causing the substrate to deform and be scrapped. The first scraper 360 is provided to directly scrape up the tape, thereby overcoming the defects caused by the residual tape. At the same time, the suction strength of the suction plate 210 is reduced, and the strength requirements for the plate moving mechanism 130 are reduced, and at the same time, energy consumption is reduced.

[0087] In some specific embodiments of the present invention, the scraping hook of the first scraping hook 360 can be thinned to reduce the contact with the workbench and reduce the wear of the pad on the workbench.

[0088] A pad is placed on the workbench, so that after the drill drills through the substrate, the head of the drill will enter the pad, making the diameter of the hole on the substrate consistent from top to bottom.

[0089] In some specific embodiments of the present invention, the first scraper hook 360 may be provided with a brush 370, and the brush 370 is used to sweep away the tape on the cover plate and the workbench.

[0090] It is easy to understand that when the scraping hook of the first scraping hook 360 is thinned, the tape is easily separated from the first scraping hook 360. In this embodiment, by providing a brush 370, the tape can be swept away to prevent the tape from remaining on the workbench and not affecting the subsequent board placement.

[0091] In order to fully utilize the materials, in some specific embodiments of the present invention, the copper plate blank can be made by splicing multiple copper plates, that is, the copper plate blank is manufactured using splicing materials.

[0092] Since there may be holes on the copper plate blank, the holes may introduce air into the suction plate disc 210, causing the suction plate function of the suction plate disc 210 to be damaged or even fail.

[0093] In some specific embodiments of the present invention, an imaging component 380 can be provided on the top of the copper plate blank bin 160. The imaging component 380 can distinguish the original hole positions on the copper plate blank. According to the original hole positions, the suction plate 210 can be adjusted horizontally so that the suction plate 210 can adsorb positions other than the original hole positions on the copper plate blank to avoid the original hole positions, thereby ensuring that the suction plate 210 adsorbs the copper plate blank normally.

[0094] Specifically, in some specific embodiments of the present invention, the lifting frame can be provided with a plurality of first rods 390 for mounting the suction plate cup 210, the suction plate cup 210 can be adjusted along the first rod 390, the extension direction of the first rod 390 is set along the first direction, and the plurality of first rods 390 are arranged along the second direction.

[0095] At the same time, the first translation seat 330 is provided with a first adjustment frame 400, and the first adjustment frame 400 is provided with a plurality of first levers 410, and the plurality of first levers 410 are located above the lifting frame, and the first levers 410 correspond to the first rod member 390, and the first lever 410 can move along the first direction to move the suction plate 210 to adjust along the first rod member 390, and the first lever 410 is provided with a downward bayonet 420, and the bayonet 420 accommodates the top of the suction plate 210, and the bayonet 420 is open on both sides along the second direction.

[0096] It is easy to understand that in this embodiment, by setting the first rod 390 and the first lever 410, the suction plate 210 can be adjusted in the first direction to avoid the original hole position on the copper plate blank, thereby ensuring that the suction plate 210 can effectively absorb the material.

[0097] The first rod 390 is provided to simplify the adjustment method, simplify the structure, and facilitate implementation.

[0098] The first lever 410 is provided with a bayonet 420 , which not only meets the adjustment requirement, but also does not affect the movement of the second translation seat 350 and the normal board placement operation.

[0099] At the same time, due to the existence of the lifting frame, the first lever 410 and the suction plate 210 can be kept away from each other up and down to avoid contact and not affect the movement.

[0100] Reference Figure 7 The present invention also provides an automatic feeding method, using the above-mentioned automatic feeding device 110 for the circuit board drilling machine 100, the automatic feeding method comprises:

[0101] The pre-setting step is to install a plurality of first rods 390 according to the distribution of the drilling holes of the substrate so that the suction plate 210 is located between two adjacent rows or columns of holes.

[0102] In some specific embodiments of the present invention, a damping pad may be provided between the first rod 390 and the suction plate 210 , thereby preventing the suction plate 210 from moving freely along the first rod 390 while meeting the position requirements.

[0103] In the material discharge step, the copper plate blanks are placed in the copper plate blank bin 160 and the cover plates are placed in the cover plate blank bin 170. At the same time, according to the product requirements of the substrate, a conveyor belt type substrate blank bin 150 or an upper and lower stacked substrate blank bin 150 is selected.

[0104] Image processing step, through the imaging component 380 to obtain the copper blank image A and the distribution image B of the suction plate 210, identify the image feature a of the original hole position of the copper blank on image A, identify the image feature b of the suction plate 210 on image B, identify the image feature c of the positioning hole common to image A and image B;

[0105] Taking the image feature c on the image A and the image B as a reference, the image A and the image B are superimposed, and it is confirmed that there is a position where the image feature a intersects with the image feature b, and the corresponding suction plate 210 is obtained in reverse;

[0106] The above is based on the intersecting shadows generated by stacking the images up and down to judge the relationship between the original hole position and the suction plate 210, which is convenient and quick.

[0107] In some specific embodiments of the present invention, in the image processing step, the image feature a can be parameterized, and the image feature a includes a center coordinate value along the first direction , the center coordinate value along the second direction and aperture , the image feature b can be parameterized, and the image feature b includes the center coordinate value along the first direction , the center coordinate value along the second direction and aperture , use numerical calculation to determine whether the original hole position intersects with the suction plate. The judgment formula is as follows:

[0108] △ - - ;

[0109] When △ is greater than zero, the original hole position does not intersect with the suction plate 210, and the corresponding suction plate 210 is not adjusted. When △ is less than or equal to zero, the original hole position intersects with the suction plate 210, and the corresponding first lever 410 is controlled to move the corresponding suction plate 210 to change , so that △ is greater than zero.

[0110] That is, the relative position relationship is accurately determined by comparing the sum of the radius of the original hole position and the radius of the suction plate 210 with the distance between the two points.

[0111] The coordinates of the center of the hole and the center of the suction plate 210 can be obtained through three points on the ring and through mathematical calculation.

[0112] At the same time, it is also convenient to preset the effective radius of the plate suction disc 210, eliminate the situation where the original hole position intersects with the plate suction disc 210 but does not affect the plate suction process, and reduce repeated adjustments.

[0113] In some specific embodiments of the present invention, the judgment values ​​△1, △2 and △3 of three adjacent suction plate discs 210 can be obtained. If △1 and △3 are greater than zero, and △2 is less than zero, and the suction plate disc 210 corresponding to △2 is located between the other two suction plate discs 210, the adjustment of the suction plate disc 210 corresponding to △2 can be canceled to reduce the adjustment content, thereby overcoming the situation where the original number of holes is large and △ cannot all be greater than zero, that is, avoiding the situation where there is no mathematical solution.

[0114] A position adjustment step, according to the suction plate disc 210 acquired in reverse, the position of the suction plate disc 210 is adjusted using the corresponding first lever 410, and the image processing step is returned to check again until the original hole position is separated from the suction plate disc 210;

[0115] A loading step, stacking the base plate blank, the copper plate blank and the cover plate blank;

[0116] In the board unloading step, after the substrate drilling is completed, the substrate products, copper plate waste and cover plate waste are placed in the corresponding waste bins.

[0117] In addition, the present invention sets an imaging component 380 and a first lever 410, so that it is possible to confirm through imaging results whether the original hole position on the copper plate intersects with the suction plate disc 210, and use the first lever 410 to separate the original hole position from the suction plate disc 210, thereby ensuring that the suction plate disc 210 can reliably suck the plate and improve the reliability of automatic loading. At the same time, the spliced ​​copper plates can also be used as copper plate blanks, which is beneficial to the recycling of materials and reduces manufacturing costs.

[0118] In this embodiment, the rotational motion can be directly driven by a motor, and the linear motion such as translation and lifting can be completed by a screw structure or a gear rack structure.

[0119] Since this embodiment does not involve improvement of the power structure, the power structure is appropriately omitted in the drawings to facilitate a clear understanding of this solution.
