DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 9 The present invention provides a technical solution: a clothing marking and drilling device with precise positioning, comprising: a workbench 1 with a hollow structure, a vent 2 for adsorption, fixation and smoke exhaust is provided on the top of the workbench 1, a piston plate 3 is provided inside the workbench 1 for lifting, the piston plate 3 comprises a metal plate and a rubber pad wrapped on the outside thereof, and is used to control the suction of the vent 2 by adjusting the size of the internal space of the workbench 1, a negative pressure part is installed at the bottom of the piston plate 3, and is used to draw a negative pressure into the closed space formed by the workbench 1 and the piston plate 3, and a sealing plug 4 for blocking the vent 2 is installed on the top of the piston plate 3, and the sealing plug 4 corresponds to the vent 2 one by one; a drilling assembly is moved and placed above the workbench 1, and the drilling assembly comprises a gantry 15 slidably installed above the workbench 1, a support block 20 and a driving part for driving the support block 20 to move and rotate are installed on one side of the gantry 15, and a laser drilling machine 21 and a hollow drilling needle 22 for drilling are installed on the outside of the support block 20, and the laser drilling machine 21 is a CO 2Laser drilling machine; the recycling component is placed on the top of the gantry 15, and the recycling component includes a recycling box 27 fixedly connected to the top of the gantry 15. The recycling box 27 is connected to the hollow drilling needle 22 through a pipeline. One side of the recycling box 27 is provided with two negative pressure parts for pumping the recycling box 27 into negative pressure. A filter tank 31 with a shaftless spiral blade 33 is arranged inside the recycling box 27. The shaftless spiral blade 33 is rotatably connected to the filter tank 31. An L-shaped plate 28 is arranged above the filter tank 31. A filter plate 29 is fixedly connected to the top of the L-shaped plate 28. The filter plate 29 and the L-shaped plate 28 are arranged parallel to each other up and down. When the L-shaped plate 28 blocks the recycling box 27, the filter plate 29 filters, and the shaftless spiral blade 33 discharges waste from the filter tank 31. When the L-shaped plate 28 is reset, the filter tank 31 filters.

[0030] It should be noted that the present invention is provided with a controller and a corresponding operation panel. During the process of clothing design and processing, the corresponding clothing and raw materials can be placed on the top of the workbench 1. The drilling method can be switched through the driving part as needed. The mechanical cutting drilling of the hollow drilling needle 22 or the laser drilling of the laser punching machine 21 can be adopted. When laser drilling, the cloth can be adsorbed on the top of the workbench 1 by negative pressure, and the piston plate 3 can be lifted and lowered by the No. 1 cylinder 8 to separate the sealing plug 4 from the vent 2. The inside of the workbench 1 is evacuated to negative pressure by the negative pressure part. Under the action of the negative pressure, the clothing or raw materials are adsorbed and fixed on the top of the workbench 1. In addition, corresponding smoke will be generated during laser drilling. The vent 2 can collect and process the generated smoke in a centralized manner. When the hollow drilling needle 22 is used for lifting and punching, The driving unit adjusts the hollow eyelet needle 22 to face vertically downward, controls the sealing plug 4 to seal the vent hole 2, so that the workbench 1 forms a flat and closed working plane, and the eyelet is drilled by lifting the hollow eyelet needle 22. The driving unit drives the gantry 15 to move above the workbench 1. Under the action of the negative pressure of the support block 20, the material after eyeleting and cutting enters the recycling box 27 through the hollow eyelet needle 22. Under the action of the timer and the controller, the L-shaped plate 28 drives the hollow eyelet needle 22 to slide back and forth in the recycling box 27. When the L-shaped plate 28 divides and seals the recycling box 27, there is negative pressure above the L-shaped plate 28, and impurities are filtered by the filter plate 29. At the same time, the shaftless spiral blade 33 cleans the internal device of the filter tank 31. When the L-shaped plate 28 is reset, the filter tank 31 filters and collects impurities, and this cycle is used to achieve automatic collection and cleaning.

[0031] like Figure 1 , 2 As shown in , 4 and 5, the negative pressure part includes a fan 6 fixedly connected to the bottom of the piston plate 3, the output end of the fan 6 is fixedly connected to the air outlet box 7, the air inlet end of the fan 6 is connected to the exhaust pipe 5, the exhaust pipe 5 passes through the piston plate 3 and extends to the workbench 1, the bottom of the workbench 1 is fixedly connected to the No. 1 cylinder 8, and the top of the No. 1 cylinder 8 is fixedly connected to the piston plate 3.

[0032] It should be noted that the lifting of the No. 1 cylinder 8 of the present invention drives the piston plate 3 to slide and connect inside the workbench 1, and the size of the space inside the workbench 1 is adjusted by the lifting position of the piston plate 3. The fan 6 continuously exhausts the space above the piston plate 3 through the exhaust pipe 5 to form a negative pressure. The volume of the space inside the workbench 1 becomes smaller, but the negative pressure is continuously extracted. Since the volume is reduced, the total amount of gas is reduced, the internal air pressure will become more negative, the negative pressure increases, and the suction force of the vent 2 will be enhanced. When the clothing or fabric is sucked and fixed, and smoke is generated during the laser processing, due to the negative pressure of the vent 2, the smoke generated in the process of adsorbing the clothing will be sucked away together. According to the size of the smoke, the height of the piston plate 3 is adjusted to improve the adsorption capacity of the piston plate 3. The smoke enters the air outlet box 7 through the exhaust pipe 5 and the fan 6. The air outlet box 7 is provided with a HEPA filter and an activated carbon filter to filter and purify the generated gas and indoor air.

[0033] like Figure 1 , 2 As shown in FIG. 3 , it also includes an end fixing assembly, which includes a support frame 9 slidably installed at the end of the workbench 1, and a No. 3 cylinder 13 for driving the support frame 9 is fixedly connected to both sides of the workbench 1, and a support roller 11 is rotatably connected between the two support frames 9. A lifting roller 10 is provided between the two support frames 9 and below the support roller 11 for lifting, and a No. 2 cylinder 12 for driving the lifting roller 10 to lift is fixedly connected to one side of the support frame 9.

[0034] It should be noted that, when the present invention performs eyelet drilling on clothing fabrics, the fabric is passed over the top of the support roller 11 and then through the bottom of the lifting roller 10 and then placed on the top of the workbench 1. When the fabric is stretched straight, the lifting roller 10 can be driven downward by the No. 2 cylinder 12 to press the fabric against the top of the workbench 1. The No. 3 cylinder 13 drives the support frame 9 to move, and the fabric is stretched to both ends by the support frame 9, so that the fabric is placed on the top of the workbench 1. The hollow eyeleting needle 22 can be used for lifting and eyeleting. After a period of eyeleting, the fabric is pulled and transported by the traction and winding structure.

[0035] like Figure 1 , 2As shown in Figures 3, 8 and 9, the driving part includes a linear module 14 and a linear module 2 16. The linear module 14 is fixedly connected to the outer side of the workbench 1. The movable slide of the linear module 14 is fixedly connected to the gantry 15. The linear module 2 16 is fixedly connected to one side of the top of the gantry 15. The movable slide of the linear module 2 16 is fixedly connected to a vertically installed linear module 3 17. The bottom of the linear module 3 17 is fixedly connected to an industrial camera 39. The movable slide of the linear module 3 17 is fixedly connected to a reducer 18. A motor 19 for driving the reducer 18 is installed on one side of the reducer 18. The output end of the reducer 18 is fixedly connected to a support block 20.

[0036] It should be noted that when the present invention drives the support block 20, the linear module 14 drives the gantry 15 to drive the support block 20 to move along the length direction of the workbench 1, the linear module 2 16 drives the support block 20 to move along the width direction of the workbench 1, and the linear module 3 17 drives the support block 20 to move along the Z-axis direction, so as to perform three-axis motion adjustment of the laser punching machine 21 and the hollow eyeleting needle 22. When switching the laser punching machine 21 and the hollow eyeleting needle 22, the motor 19 drives the reducer 18 to work, and the reducer 18 is a worm gear reducer. The reducer 18 drives the support block 20 to rotate 90°, so as to switch the position of the laser punching machine 21 and the hollow eyeleting needle 22. When punching holes in corresponding positions of clothing placed on the top of the workbench 1, by installing an industrial camera 39 and cooperating with a corresponding image processing algorithm, the system can locate the object by capturing the image and extracting feature points or feature patterns, and cooperate with the driving unit to punch holes at designated positions.

[0037] like Figure 8 , 9 As shown, the hollow eyeleting needle 22 passes through the middle of the support block 20 and is slidably connected to the support block 20. A baffle is fixedly connected to the top of the hollow eyeleting needle 22, and a spring 23 is installed between the baffle and the support block 20. The outer lifting frame 26 of the hollow eyeleting needle 22 is slidably connected to the support block 20. A motor 24 is fixedly connected to one side of the support block 20 through a bracket. An eccentric wheel 25 is fixedly connected to the output end of the motor 24, and the eccentric wheel 25 is frictionally connected to the top of the lifting frame 26.

[0038] It should be noted that, when the hollow eyeleting needle 22 is driven by the present invention, the height of the hollow eyeleting needle 22 is adjusted by the linear module three 17 and the support block 20, and then the eccentric wheel 25 is driven by the motor two 24 to select, and the eccentric wheel 25 drives the lifting frame 26 to move downward under the action of extrusion, and the lifting frame 26 drives the hollow eyeleting needle 22 to move downward while compressing the spring 23. When the other end of the eccentric wheel 25 contacts the lifting frame 26, the spring 23 drives the hollow eyeleting needle 22 to reset, and this cycle is repeated to complete the punching and drilling of the hollow eyeleting needle 22.

[0039] like Figure 6 , 7 As shown, the L-shaped plate 28 and the filter plate 29 are inserted from one side of the recycling box 27 and are slidably connected to the recycling box 27. The L-shaped plate 28 and the filter plate 29 are both provided with rubber pads. A No. 4 cylinder 30 is fixedly connected to one side of the L-shaped plate 28. The output end of the No. 4 cylinder 30 is fixedly connected to the recycling box 27. The top and one end of the filter tank 31 are open structures. The recycling box 27 is provided with a discharge port at a position corresponding to the filter tank 31. The discharge port is provided with a rubber sheet 38. The top of the rubber sheet 38 is fixedly connected to the limit plate 37. A rubber sheet 38 for sealing the limit plate 37 is fixedly connected to one side of the L-shaped plate 28, a motor 32 is fixedly connected to one side of the recovery box 27, the output end of the motor 32 is fixedly connected to the shaftless spiral blade 33, a through hole 34 is opened at the bottom of the filter tank 31, and the negative pressure part 2 includes a fan 2 35 fixedly connected to the outside of the recovery box 27, the input end of the fan 2 35 is respectively connected to the middle part of the L-shaped plate 28 and the bottom of the recovery box 27 through a Y-shaped pipe and a solenoid valve, and the output end of the fan 2 35 is fixedly connected to the filter box 36.

[0040] It should be noted that the hollow eyelet needle 22 of the present invention is connected to the top of the recycling box 27 through a PVC steel wire hose, and the second fan 35 draws the interior of the recycling box 27 into a negative pressure. Under the action of the negative pressure, the material left by the eyelet drilling inside the hollow eyelet needle 22 enters the recycling box 27 under the action of the PVC steel wire hose. Because the filter tank 31 is a U-shaped structure and a through hole 34 is provided at its bottom, the rags remain in the filter tank 31 after filtering. Under the action of the timer, the filter tank 31 quickly contracts and drives the L-shaped plate 28 and the No. 1 cylinder 8 of 29 to insert into the interior of the recycling box 27. The L-shaped plate 28 divides the recycling box 27. Under the action of the air duct and the solenoid valve, the eccentric wheel 25 draws a negative pressure state above the L-shaped plate 28, and the rags are filtered on the top of the filter plate 29. At this time, the limit plate 37 and the rubber sheet 38 are misaligned, and the motor three 32 drives the shaftless spiral blade 33 to rotate The shaftless spiral blade 33 discharges the filtered rags inside the filter tank 31 from one end of the limit plate 37. A corresponding material collection box is provided at one end of the recovery box 27. After the timing is over, the No. 4 cylinder 30 drives the L-shaped plate 28 to quickly reset. The limit plate 37 is now blocked on the outside of the rubber sheet 38. The solenoid valve of the air duct below the filter tank 31 is opened, and the rags filtered on the top of the filter plate 29 are scraped off by the recovery box 27 and fall into the filter tank 31. Under the action of negative pressure and the through hole 34, the filter tank 31 filters and collects the passing rags. In this reciprocating cycle, automatic filtering and cleaning and collection are realized. A filter net is provided inside the filter box 36 to filter the passing air. During laser drilling, when the smoke is large, the eccentric wheel 25 can also be opened to absorb the smoke and dust through the hollow drilling needle 22 and then filter it to ensure the air quality of the working environment.
