[0042] As shown in Figures 1 to 11 The automatic drill press includes a machine head, and the machine head includes a machine head fixing seat 500 and a multi-color automatic drill feeding and drilling device installed on the machine head fixing seat 500. A frame is arranged below the machine head fixing seat 500, and a rubber sheet can be embedded on the frame, and the drill 201 can be adhered to the rubber sheet. Here, the transverse extension direction of the machine head fixing seat 500 is defined as the X direction, the front-rear direction is defined as the Y direction, and the up-down direction is defined as the Z direction. The frame can drive the rubber sheet to move horizontally along the X direction and the Y direction.

[0043] The multi-color automatic drill feeding and drilling device includes a multi-color automatic drill feeding component and a suction nozzle component 200. The multi-color automatic drill feeding component includes at least two automatic drill feeding components 100 arranged side by side along the X direction. Each automatic drill feeding component 100 can feed drills of one color (or specification), and the multiple automatic drill feeding components can feed drills of multiple colors (or specifications). The multi-color automatic drill feeding component moves along the X direction, and one of the automatic drill feeding components 100 is positioned to correspond to the suction nozzle component 200 to realize color changing. Another automatic drill feeding component 100 originally positioned to correspond to the suction nozzle component 200 is misaligned with the suction nozzle component 200. After the color changing is completed, the suction nozzle component 200 can correspondingly drill vertically.

[0044] The color changing structure is provided for the multi-color automatic drill feeding component, and a color changing driver is provided to drive the multi-color automatic drill feeding component to move along the X direction to realize color changing. In one embodiment, the color changing driver includes a color changing motor and a linear motion mechanism driven by the color changing motor, wherein the linear motion mechanism drives the multi-color automatic drill feeding component to move along the X direction. For example, the linear motion mechanism is a screw nut mechanism including a screw rod and a nut, the screw rod is connected with the color changing motor, and the nut is connected with the multi-color automatic drill feeding component. Alternatively, the linear motion mechanism can also be a gear and rack mechanism including meshed gears and racks, the gears are connected with the color changing motor, and the racks are connected with the multi-color automatic drill feeding component.

[0045] In some embodiments, the automatic drill feeding component 100 includes a drill storage tank 11, a drill sorting ring 12, and a drill sorting ring driving motor 13. The bottom of the drill storage tank 11 is provided with a slot, the drill sorting ring 12 is a circular ring, the axial direction of which is the X direction, a partial circular arc portion of the drill sorting ring 12 passes through the slot and is located in the drill storage tank 11, the drill sorting ring 12 is provided with drill arranging grooves 121 distributed along the circumference, and the drill sorting ring driving motor 13 drives the drill sorting ring 12 to rotate. During the rotation of the drill sorting ring 12, a partial circular arc portion always passes through the slot, and the drills 201 in the drill storage tank are arranged in the drill arranging grooves 121, and after the drills are arranged in the drill arranging grooves 121, the drills in the drill arranging grooves are transported to the lower side of the suction nozzle during the rotation of the drill sorting ring 12.

[0046] The suction nozzle component 200 is relatively fixed to the inner side of the drill sorting ring 12 and is fixed in the X direction, and when color changing is performed, the multi-color automatic drill feeding component moves along the X direction, so that the suction nozzle component 200 corresponds to one of the automatic drill feeding components 100 in the X direction, thereby cooperating with one of the automatic drill feeding components 100, i.e., the automatic drill feeding component 100 feeds the drill 201 to the lower side of the suction nozzle component 200.

[0047] In this embodiment, the suction nozzle component 200 adopts a vertical drilling structure, which includes a suction nozzle and a suction nozzle up-down driver, the nozzle of the suction nozzle is downward to adsorb the drill fed to the lower side of the suction nozzle by the automatic drill feeding component 100 and release the adsorbed drill, the suction nozzle up-down driver drives the suction nozzle to move up and down, and the movement path of the suction nozzle passes through the drill arranging groove 121 when drilling. When the drill sorting ring 12 rotates to feed the drill 201 in the drill arranging groove 121 to the lower side of the suction nozzle, the suction nozzle moves downward and adsorbs the drill in the drill arranging groove above the drill arranging groove. Then, when vertical drilling is performed, the suction nozzle moves downward, and after the movement path of the suction nozzle passes through the drill arranging groove, the suction nozzle continues to move downward to feed the drill to the lower side of the adhesive tape, at this time, the suction nozzle releases the suction force, so that the drill is adhered to the adhesive tape and stays on the adhesive tape.

[0048] As shown in Figure 5 , Figure 7 and Figure 8 , the suction nozzle has a retreat position, a suction position and a punching position along the up-down movement direction, and the lower end of the suction pipe of the suction nozzle corresponds to the retreat height, the suction height and the punching height. When it is necessary to change the color to arrange other color or specification drills, the suction nozzle up-down driver will lift the suction nozzle to the retreat position, and the lower end of the suction pipe corresponds to the retreat height, leaving a movable space for the multi-color automatic drill feeding component. The multi-color automatic drill feeding component will move to the position of the automatic drill feeding component of the next color or specification under the drive of the color change driver. When it is necessary to suck the drill, the suction nozzle up-down driver will lift the suction nozzle to the suction position, and the lower end of the suction pipe corresponds to the suction height. When the drill follows the drill sorting ring 12 to rotate to the lower drill stop bar 31, the suction nozzle will suck the drill. When it is necessary to punch the drill, the suction nozzle up-down driver drives the suction nozzle to move downward to feed the drill to the lower adhesive tape, the suction nozzle releases the suction force, and the drill adheres to and stays on the adhesive tape, and the suction nozzle retreats to the suction position.

[0049] The multi-color automatic drill feeding and punching device in the embodiment has at least two automatic drill feeding components arranged side by side along the X direction, and each automatic drill feeding component can realize the feeding of one color. The multi-color automatic drill feeding component moves along the X direction to realize color change, so that the multiple automatic drill feeding components can feed the drills alternately, thereby realizing multi-color feeding and multi-color ironing. The four or more colors and specification color matching can also be easily realized, the color matching accuracy can be guaranteed, and the diversity and aesthetic degree of the pattern can be improved.

[0050] The traditional ironing device adopts the design structure of disc drill arrangement. Referring to the Chinese invention patent with the publication number CN102477670A, the bead storage disc is a disc structure, a circle of bead grooves is arranged near the edge of the bead storage disc, the bead storage disc is axially perpendicular to the horizontal direction (the horizontal direction has X and Y coordinates), and a large space is occupied in the X direction. In the embodiment, the automatic drill feeding component includes a drill sorting ring rotating around the X direction (X axis). The drill sorting ring driving motor drives the drill sorting ring to rotate around the X direction. The drill sorting ring rotating process passes through the drill storage groove, so that the drills in the drill storage groove are arranged in the drill arrangement groove, and the drill sorting ring transports the drills in the drill arrangement groove to the lower side of the suction nozzle. In this way, on the one hand, the design structure of the traditional ironing device is changed from the disc drill arrangement to the circular ring drill arrangement, so that more automatic drill feeding components can be accommodated in the corresponding X direction space, thereby completing the drill arrangement work of more colors (compared with the design structure of the traditional disc drill arrangement, the traditional two colors are changed to four colors, five colors, six colors or even more colors).

[0051] In addition, the suction nozzle part is fixed in the X direction, and when changing color, the multi-color automatic drill feeding part moves in the X direction, so that the suction nozzle part corresponds to one of the automatic drill feeding parts in the X direction, and therefore one suction nozzle part can be provided. Corresponding to the design of the drill sequencing ring rotating around the X axis, the suction nozzle part is fixed inside the drill sequencing ring, so that the drill sequencing ring can send a drill to the position below the suction nozzle when it rotates one station (the angle between adjacent two stations and adjacent two drill slot intervals is the same). At the same time, the traditional angle switching suction drill vertical drilling is changed to a direct vertical drilling design structure, the suction nozzle is driven up and down by the suction nozzle up and down driver, when the drill sequencing ring sends the drill to the position directly below the suction nozzle, the suction nozzle moves downward, and stays in the suction drill position above the drill slot, and the drill in the drill slot is sucked; when vertical drilling, the suction nozzle moves downward, and the movement path of the suction nozzle continues to move downward after passing through the drill slot, and the drill is sent out to the paper below, at this time the suction nozzle releases the suction force, and the drill is adhered to the paper and stays on the paper. Compared with the traditional angle switching suction drill vertical drilling, it does not need to switch the angle, only needs to move up and down, the action is relatively less, and the drill can be continuously drilled, so that the vertical drilling structure can improve the drilling efficiency, and the drilling efficiency can be improved by 1 times.

[0052] Further, since the traditional direct drill welding on the fabric is changed, the drill is arranged on the paper, and the drill head is in soft contact with the paper, the mechanical vibration problem is solved, and the speed of the drill sequencing ring can be increased by several times.

[0053] Therefore, the circular ring drill arrangement of the automatic drill feeding part cooperates with the direct vertical drilling design structure of the suction nozzle part, the drill feeding and drilling are smooth, the drill can be continuously fed and drilled, the drill feeding efficiency and drilling efficiency can be guaranteed, and the drill welding efficiency is improved.

[0054] For the color changing structure, specifically, the head fixing seat 500 extends along the X direction, and the front side is provided with a head guide rail 51 extending along the X direction. The multi-color automatic drill feeding component is slidably installed on the front side of the head fixing seat 500 through the head guide rail 51, and the drill sorting ring driving motor 13 is installed on the rear side of the head fixing seat. The multi-color automatic drill feeding component is installed on the drill feeding component support 10, which includes a fixed plate 101 provided on both sides of at least two automatic drill feeding components 100 arranged side by side along the X direction, a fixed beam 102 connecting the two fixed plates 101, and a head sliding block 103 connected with the fixed plate 101, which slidably cooperates with the head guide rail 51. Among them, the fixed plate 101 is provided with a through hole, the suction nozzle mechanism fixing seat 52 extends along the X direction, passes through the through hole and the inner side of the drill sorting ring 12, and the two ends of the suction nozzle mechanism fixing seat 52 are provided with bending parts which are fixed on the front side of the head fixing seat 500. The suction nozzle component 200 is fixed on the suction nozzle mechanism fixing seat 52. The fixed beam 102 is an L-shaped plate, including a horizontal bottom plate 1021 and a vertical plate 1022 extending upward from the front end of the horizontal bottom plate, and the drill storage groove 11 is fixed with the vertical plate 1022.

[0055] In some embodiments, a drill ejecting piece 14 is arranged on the radial outer side of the drill sorting ring 12, which is arranged close to the side of the drill sorting ring 12 away from the drill storage groove 11. In this way, the drill can be arranged in the drill sorting groove and then pass through the drill ejecting piece 14. When the drill in the drill sorting groove passes through the drill ejecting piece, if the drill is correctly arranged in the drill sorting groove, the drill ejecting piece will not eject the drill from the drill sorting groove, and if the drill is incorrectly arranged in the drill sorting groove, the drill ejecting piece will eject the drill from the drill sorting groove.

[0056] Preferably, the drill ejecting piece 14 is a brush, and the brush contacts the outer circle of the drill sorting ring. As shown in the figure, the drill sorting ring rotates counterclockwise, the direction of the brush is opposite to the rotating direction of the drill sorting ring, and the direction of the brush has an included angle with the radial direction of the corresponding position of the drill sorting ring, and the included angle is less than or equal to 30 degrees. It can be understood that other components can be used to replace the brush as the drill ejecting piece, such as silica gel and similar materials.

[0057] Specifically, the upper part of the drill storage tank 11 is rectangular in structure, and the bottom part is circular arc structure, the circular arc opening part faces the rear side, and its front view is rectangular, which is beneficial to arrange more automatic drill feeding components 100 side by side along the X direction. In addition, the drill storage tank 11 is provided with a drill flow limiting plate 15. The drill flow limiting plate 15 is arranged close to the bottom wall of the drill storage tank, and the bottom wall of the drill storage tank is partially circular arc-shaped corresponding to the outer circle of the drill sorting ring. Correspondingly, the drill flow limiting plate 15 is also circular arc-shaped, and a flow limiting cavity is formed between the drill flow limiting plate 15 and the bottom wall of the drill storage tank. A flow limiting hole 151 is provided at a position corresponding to the slot, so that part of the drill in the drill storage tank passes through the flow limiting hole into the flow limiting cavity, and through the flow limiting effect, the drill enters the drill discharge slot when the drill sorting ring rotates. In addition, the outer circle of the drill sorting ring is provided with a drill protection baffle 16, which is located outside the drill storage tank 11 and extends in a circular arc shape outside the outer circle of the drill sorting ring to prevent the drill from falling out of the drill discharge slot. The drill protection baffle 16 is provided with a drill removing element mounting seat 152, and the brush handle can be fixed in the mounting groove of the drill removing element mounting seat 152 by screws.

[0058] It can be understood that an inner support bushing 123 can be arranged inside the multi-color automatic drill feeding component, the inner support bushing 123 passes through the multi-color automatic drill feeding component, and the two ends are connected with the fixed plates 101 on both sides of the drill feeding component support 10. The drill sorting ring 12 is supported for rotation by the inner support bushing 123. The inner support bushing 123 is provided with a suction nozzle guide groove corresponding to below the suction nozzle, and the suction nozzle moves up and down and passes through the suction nozzle guide groove.

[0059] In some embodiments, the suction nozzle up-down driver includes an up-down guide rail 26 and a suction nozzle driving motor 29, the suction nozzle is slidably connected with the up-down guide rail, and the suction nozzle driving motor 29 drives the suction nozzle to move up and down along the up-down guide rail 26. The output shaft of the suction nozzle driving motor is connected with a swing rod 28, the suction nozzle is connected with an up-down moving block 27, and the swing rod 28 is movably connected with the up-down moving block 27. The up-down moving block 27 is provided with a movable groove 271, the swing rod 28 is connected with a rotating element 281, such as a bearing, and the rotating element is arranged in the movable groove. When the swing rod swings, the rotating element moves in the movable groove and drives the up-down moving block to move up and down.

[0060] Specifically, the suction nozzle comprises a suction pipe 21 and a buffer spring 23 connected with the suction pipe, the buffer spring 23 provides buffering when the suction pipe 21 moves up and down. Mainly, when the drill is in contact with the adhesive tape, there will be a certain impact, and the buffer spring provides buffering at this time, which can avoid the impact on the suction pipe. In this way, the drill and the adhesive tape adopt a flexible contact mode, which can also solve the problem of mechanical vibration. The suction nozzle further comprises a joint 24 and a guide sleeve 22, the upper end of the guide sleeve 22 is connected with the joint 24, the upper part of the suction pipe 21 is movably inserted into the guide sleeve 22, the upper part of the suction pipe 21 is provided with a flange part, the lower end of the buffer spring 23 is connected with the flange part, and the upper end of the buffer spring 23 is connected with the lower end of the joint. In addition, the joint 24 is provided with a lateral interface connected with the air pipe to control the suction nozzle. The upper end of the joint is connected with an upper and lower sliding block 25 through a screw rod and a locking nut, the upper and lower sliding block 25 is in sliding fit with an upper and lower guide rail 26, and the upper and lower sliding block 25 is fixed with an upper and lower moving block 27.

[0061] Further, the suction nozzle is provided with an air pressure sensor, the air pressure of the suction nozzle is detected by the air pressure sensor to determine whether the drill is sucked by the suction nozzle. When the drill is sucked by the suction nozzle, the drill sorting ring 12 stops rotating, and the drill is sent out through the drill arranging groove by the suction nozzle. If the drill is not sucked by the suction nozzle, the drill sorting ring 12 continues to rotate until the drill is sucked, so that the detection can guarantee that the pattern on the adhesive tape is perfect.

[0062] In some embodiments, a lower drill stopper assembly 300 can also be provided, the lower drill stopper assembly 300 comprises a lower drill stopper 31 arranged below the suction nozzle, and the lower drill stopper 31 below each suction nozzle is connected as a whole along the X direction. The lower drill stopper 31 is provided with a groove 311 corresponding to the position of the drill sorting ring, because the gap between the lower drill stopper 31 and the drill sorting ring is small, and the drill will partially protrude from the drill arranging groove, therefore, the groove 311 is beneficial to the rotation of the drill sorting ring. The lower drill stopper 31 has a drill blocking state and a drill avoiding state. In the drill blocking state, the lower drill stopper blocks the space below the suction nozzle and is located below the drill arranging groove of the drill sorting ring. In the drill avoiding state, the lower drill stopper leaves out the space below the suction nozzle, and the drill can pass through the drill arranging groove to be placed downward. The lower drill stopper 31 is arranged opposite to the drill arranging groove to be sucked, which can avoid the drill from falling off from the drill arranging groove before the drill is sucked by the suction nozzle, and improves the success rate of sucking the drill.

[0063] In order to drive the action of the lower drill stopper, the lower drill stopper 31 is connected with a lower drill stopper front and rear driver, which comprises a front and rear guide rail and a lower drill stopper driving motor 35, which drives the lower drill stopper 31 to move forward and backward along the front and rear guide rail. When switching from the drill blocking state to the avoiding state, the lower drill stopper front and rear driver drives the lower drill stopper 31 to move backward, exposing the drill row groove 121. Specifically, a transmission assembly is provided between the lower drill stopper driving motor 35 and the lower drill stopper 31, which comprises a front and rear rack 32 and a fourth gear 33, the front and rear rack 32 is connected with the lower drill stopper 31, and the front and rear rack 32 is engaged with the fourth gear 33. In addition, the bottom rear side of the fixed plate 101 on both sides is connected with a rear mounting beam 104, which is located at the rear side of the machine head fixing seat 500, and a rotating shaft 34 is provided between the rear mounting beam and the bottom connecting part of the fixed plate 101, one end of the rotating shaft is located outside the connecting part of the rear mounting beam and the bottom of the fixed plate 101, and is connected with the fourth gear 33, and the other end of the rotating shaft is connected with the output shaft of the lower drill stopper driving motor 35 through a second belt transmission assembly 36, wherein the second driven pulley in the second belt transmission assembly 36 is fixed on the rotating shaft 34. The front and rear guide rails can be arranged on the lower side of the fixed plate 101.

[0064] As shown in Figure 9 and Figure 10 In some embodiments, each automatic drill feeding component is provided with a drill sequencing ring driving motor 13 to drive the drill sequencing ring 12, which can be referred to as a multi-motor driven drill row structure. Figure 2 As shown in Figure 2 , for the multi-motor driven drill row structure, the drill sequencing ring driving motor 13 is located at the rear side of the machine head fixing seat 500, and can be installed on the rear mounting beam and the machine head fixing seat through a motor support. Due to space limitations, not all the drill sequencing ring driving motors 13 are arranged side by side in a straight line, but adjacent two drill sequencing ring driving motors 13 are staggered. A second gear 18 is installed on the rotating shaft corresponding to each drill sequencing ring, and a first belt transmission assembly 17 is provided between the second gear 18 and the corresponding drill sequencing ring driving motor 13, wherein the first driven pulley in the first belt transmission assembly 17 is fixed side by side with the second gear 18, so that the drill sequencing ring driving motor 13 drives the second gear 18 to rotate through the first belt transmission assembly 17. The drill sequencing ring 12 is coaxially fixed with a third gear 122, and the second gear 18 is engaged with the third gear 122, so that the second gear rotates and drives the third gear 122 to rotate, and the drill sequencing ring 12 rotates synchronously with the third gear 122.

[0065] The automatic hot-drill machine works by pouring drills into the drill storage tank 11, and the automatic drill feeding component operates. The drill sorting ring drive motor 13 drives the drill sorting ring 12 to rotate counterclockwise. When the drill sorting ring 12 rotates, the drills 201 poured into the drill storage tank 11 will automatically fall into the drill discharge groove 121 of the drill sorting ring 12 due to their own weight. When the drills in the discharge groove 121 follow the rotation of the drill sorting ring 12, they pass the drill removal part 14. If the drill falls into the discharge groove 121 correctly, it will not be brushed off. Otherwise, it will be brushed off and wait for the next drop. This can effectively ensure that the drills discharged by the drill sorting ring 12 have a consistent surface.

[0066] When the drill follows the drill sorting ring 12 and rotates to the lower drill stop 31, the suction nozzle will hold the drill and prepare to drill. At this time, the front and rear drivers of the lower drill stop 31 drive the lower drill stop 31 to move backward, exposing the drill slot 121. Then, the upper and lower drivers of the suction nozzle drive the suction nozzle to move downward and send the drill out onto the adhesive paper below. The suction nozzle releases the suction force, allowing the drill to stick to the adhesive paper and stay on the adhesive paper. The suction nozzle returns to the drill holding position. At this time, the embroidery frame with the adhesive paper will move one position according to the design requirements to prepare for placing the next drill.

[0067] When it is necessary to change the color of the drills to other colors or specifications, the suction nozzle up and down driver will raise the suction nozzle to the top, i.e., the clearance position, to make room for the automatic drill feeding component 100 to move. The automatic drill feeding component 100 will move to the position of the drill storage tank 11 of the next color or specification under the drive of the color changing mechanism.

[0068] Repeat the above steps according to the design to leave beautiful patterns on the adhesive tape.

[0069] like Figure 11 As shown, in some embodiments, a single-motor driven drilling structure can also be used, with only one drilling ring drive motor 13. The single-motor driven drilling structure includes a first rotating component driven to rotate by the drilling ring drive motor 13 and a second rotating component that drives the drilling ring to rotate. The first rotating component drives the second rotating component to rotate, and during color change, the first rotating component and the second rotating component move relative to each other in the X direction to achieve separation and transmission connection.

[0070] Here, the first rotating member is a first gear 194, and the second rotating member is a second gear 18. The second gear is provided in the same manner as the above-described embodiment in which each automatic pipe feeding component is provided with a pipe sorting ring driving motor 13 to drive the pipe sorting ring 12. A third belt transmission assembly is provided between the pipe sorting ring driving motor 13 and the first gear 194. The first gear 194 is mounted on a first gear shaft, and the third belt transmission assembly includes a third driven belt pulley mounted on the first gear shaft, a third driving belt pulley mounted on an output shaft of the pipe sorting ring driving motor, and a third transmission belt connecting the third driving belt pulley and the third driven belt pulley. Thus, the first gear 194 is fixed in the X direction, and when the color is changed, the multi-color automatic pipe feeding component moves in the X direction, and the second gear of one of the automatic pipe feeding components is separated from the first gear. After the color is changed, the second gear of another automatic pipe feeding component is in transmission connection with the first gear. It can be understood that the first rotating member and the second rotating member can also be replaced by other rotating members.

[0071] As shown in Figure 2 In order to facilitate the installation of the third belt transmission assembly and the pipe sorting ring driving motor, a transmission seat 19 is mounted on the rear side of the machine head fixing seat. The transmission seat 19 is L-shaped and includes a vertical section 191 and a horizontal section 192. The vertical section is fixed to the rear side of the machine head fixing seat, and the front end of the horizontal section extends forward below the machine head fixing seat. A through groove 193 is provided in the middle of the vertical section and the horizontal section. The second gear 18 is provided on the side of the front end of the horizontal section, the third driven belt pulley is located inside the through groove 193, and the third transmission belt is also located inside the through groove 193. The pipe sorting ring driving motor 13 is mounted on a motor seat 131, and the motor seat 131 is connected to the transmission seat. The motor seat includes a front section, a rear section, and a middle section. The pipe sorting ring driving motor is mounted on the side of the rear section, the front section extends in the X direction and is connected to the transmission seat.

[0072] When each color pipe is fed, the pipe sorting ring driving motor drives the pipe sorting ring of one of the automatic pipe feeding components. The first rotating member is driven to rotate by the pipe sorting ring driving motor, the second rotating member drives the pipe sorting ring to rotate, and the first rotating member drives the second rotating member to rotate. When the color is changed, the first rotating member and the second rotating member move relatively in the X direction to achieve separation and transmission connection. In this way, each automatic pipe feeding component does not need to be provided with a pipe sorting ring driving motor, which can reduce the number of motors and significantly reduce the cost.

[0073] In the above-described embodiments, whether it is a multi-motor driving pipe arrangement structure or a single-motor driving pipe arrangement structure, the shaft not only has the function of mounting the second gear, but also simultaneously serves as part of the downhole stopper assembly 300 for mounting the fourth gear 33 and the second driven belt pulley in the second belt transmission assembly 36.

[0074] The above descriptions are only specific embodiments of the utility model, and the protection scope of the utility model is not limited to this, and the skilled in the art should understand that the utility model includes but is not limited to the content described in the drawings and the above specific embodiments.Any modification not deviating from the function and structural principle of the utility model will be included in the scope of claims.
