Technical Field

[0001] The invention relates to the technical field of laser cutting devices, in particular to a laser cutting device for tarpaulin processing. Background Art

[0002] Tarpaulin is a waterproof material with high strength, good toughness and softness. It is often used as canvas, polyester with polyurethane coating or made into polyethylene plastic. Tarpaulin usually has strong grommets at the corners or edges to facilitate rope binding, hanging or covering. Tarpaulin is a textile with a wide range of applications. Its main uses include but are not limited to the following aspects: it can be used as a material for temporary cargo sheds and temporary warehouses to provide shelter for materials, goods and equipment; the tarpaulin has a flat surface and bright colors, which is suitable for printing various advertisements, slogans, patterns, etc.; it can be used as a tent, parasol, picnic mat, etc., to provide people with a comfortable resting environment. In addition, tarpaulin can also be used to make toys such as kites and sailboats to enrich people's entertainment life. Due to different usage requirements, tarpaulins need to be cut into different sizes, and the laser cutting device for tarpaulins is a laser device specially used for cutting materials such as tarpaulins. This device uses the high energy density characteristics of the laser beam to focus the laser beam into a very small light spot through a focusing lens, and irradiates it onto the surface of the tarpaulin, so that the material quickly melts, vaporizes or reaches the ignition point, thereby achieving precise cutting. The laser cutting device for tarpaulins has the following advantages: The laser beam is fine, which can achieve high-precision cutting and meet the fine processing requirements of tarpaulins and other materials. The cutting speed is fast and the layout is flexible, which can greatly improve production efficiency. There is no mechanical contact during the laser cutting process, and no need to use tools and coolants, which reduces pollution and energy consumption.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The chain plate vacuum suction cup driving mechanism of the present invention can suck the tarpaulin products and waste materials and drive them to move, so that they enter the corresponding waste slot or product slot. During the sucking, the driving screw is started according to the position of the tarpaulin product to adjust the position of the electric telescopic cylinder mounting plate of the tarpaulin unloading driving mechanism, and the electric telescopic cylinder mounting plate of the tarpaulin unloading driving mechanism drives the electric telescopic cylinder of the tarpaulin unloading driving mechanism to move horizontally. The electric telescopic cylinder of the tarpaulin unloading driving mechanism drives the driving box to move through the supporting frame, and the driving box drives the driving rod to move horizontally, so that the position of the chain plate vacuum suction cup driving mechanism is aligned with the tarpaulin product. The air inlet three-way valve is adjusted to connect the main air inlet pipe and the main air suction pipe of the vacuum suction cup, and the vacuum pump is started. The negative pressure generated by the vacuum pump allows air to be sucked from the vacuum suction cup, and enters the diverter through the second vacuum suction cup branch air suction pipe. The diverter collects the air into the first vacuum suction cup branch air suction pipe, and the air in the first vacuum suction cup branch air suction pipe is then collected into the main air suction pipe of the vacuum suction cup through the diverter, so that the vacuum suction cup generates negative pressure, and the electric telescopic cylinder of the tarpaulin unloading drive mechanism is extended to drive the drive box to move downward, so that the vacuum suction cup is adsorbed on the upper surface of the tarpaulin product, thereby fixing the tarpaulin product. At this time, the drive The drag chain between the dynamic drive frame and the laser cutting workbench allows the vacuum suction cup to be placed above the product slot. When the tarpaulin product is long, the drive motor can be driven, and the drive motor drives the active sprocket to rotate, and the active sprocket drives the driven sprocket to rotate through the chain, and the driven sprocket drives the drive rod to rotate, and the drive rod drives the installation chain plate to roll through the drive sprocket, so that the vacuum suction cup can roll, and the second vacuum suction cup sub-suction pipe valve is used to adjust the on-off of the second vacuum suction cup sub-suction pipe. When the vacuum suction cup moves to the lower end of the chain plate vacuum suction cup drive mechanism, the second vacuum suction cup sub-suction pipe valve can be opened. When it leaves the chain plate When the vacuum suction cup driving mechanism is at the lower end, the second vacuum suction cup suction pipe valve can be closed to drag the tarpaulin product into the product slot. At this time, the waste is grabbed by the chain plate vacuum suction cup driving mechanism and driven to the top of the waste slot. The waste enters the waste slot in the above manner, which solves the problem that the existing laser cutting device limits the two ends of the fabric to avoid wrinkles during cutting. However, due to the different shapes of tarpaulin products, if the tarpaulin products and waste materials on the workbench are missed when cleaning after cutting, they will be placed under the tarpaulin, which will make the tarpaulin that needs to be cut later uneven, thereby affecting the cutting qualification rate.

[0018] 2. In the present invention, the CCD camera takes a picture of the image after cutting and sends it to the control unit of the laser cutting device body. The control unit analyzes and identifies the image processing algorithm to determine whether the cut pattern is deviated or shifted. When a problem is found, the cutting operation is stopped to facilitate the staff to adjust the fault in time, thereby preventing more unqualified tarpaulin products from being cut. After the cutting operation is completed, the CCD camera observes the position of the tarpaulin product and the waste material after cutting, thereby recording the position of the tarpaulin product and the waste material, which is convenient for the subsequent suction operation of the tarpaulin product and the waste material position. Through a CCD camera, different usage requirements can be met, thereby reducing equipment costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] See also Figure 1-8 An embodiment of the present invention is as follows: a laser cutting device for tarpaulin processing comprises a laser cutting device body 1, a laser cutting device body 1 is provided at the lower end of the laser cutting device body 1, a driving frame 2 is slidably installed above the laser cutting device body 1, a laser fixing seat 3 is slidably installed above the driving frame 2, a tarpaulin unloading driving mechanism 36 is installed below the rear side of the driving frame 2, a waste trough 18 is provided at the rear end of the second sprocket 39 of the laser cutting workbench 38, and a product trough 19 is provided at the rear side of the waste trough 18.

[0030] After the cutting operation is completed, the CCD camera 50 observes the position of the cut tarpaulin product and the waste material. After the observation is completed, the driving screw 40 is started to adjust the position of the electric telescopic cylinder mounting plate 41 of the tarpaulin unloading driving mechanism according to the position of the tarpaulin product. The electric telescopic cylinder mounting plate 41 of the tarpaulin unloading driving mechanism drives the electric telescopic cylinder 21 of the tarpaulin unloading driving mechanism to move horizontally. The electric telescopic cylinder 21 of the tarpaulin unloading driving mechanism drives the driving box 22 to move through the support frame 23. The driving box 22 drives the driving rod 27 to move horizontally, so that the position of the chain plate vacuum suction cup driving mechanism 29 is aligned with the tarpaulin product. At this time, the air intake three-way valve 12 is adjusted to connect the main air intake pipe 11 and the vacuum suction cup main suction pipe 14, and the vacuum pump 9 is started. The negative pressure generated by the vacuum pump 9 allows air to be sucked from the vacuum suction cup 32, and enters the diverter 44 through the second vacuum suction cup branch suction pipe 33. The diverter 44 collects the air into the first vacuum suction cup branch suction pipe 45. The air in the first vacuum suction cup branch suction pipe 45 is then collected into the vacuum suction cup main suction pipe 14 through the diverter 44, so that the vacuum suction cup 32 generates negative pressure, and the electric telescopic cylinder 21 of the tarpaulin unloading drive mechanism drives the drive box 22 to move downward, so that the vacuum suction cup 32 is adsorbed on the upper surface of the tarpaulin product, thereby fixing the tarpaulin product. At this time, the drag chain between the driving frame 2 and the laser cutting workbench 38 is driven to place the vacuum suction cup 32 above the product slot 19. When the size of the tarpaulin product is long, the driving motor 24 can be driven, and the driving motor 24 drives the active sprocket 25 to rotate. The active sprocket 25 drives the driven sprocket 26 to rotate through the chain 28, and the driven sprocket 26 drives the driving rod 27 to rotate. The driving rod 27 drives the installation chain plate 31 to roll by driving the first sprocket 35, so that the vacuum suction cup 32 rolls, and the second vacuum suction cup is divided into the suction pipe valve. 34 adjusts the on-off of the second vacuum suction cup suction pipe 33. When the vacuum suction cup 32 moves to the lower end of the chain plate vacuum suction cup driving mechanism 29, the second vacuum suction cup suction pipe valve 34 can be opened. When leaving the lower end of the chain plate vacuum suction cup driving mechanism 29, the second vacuum suction cup suction pipe valve 34 can be closed, thereby dragging the tarpaulin product into the interior of the product groove 19. At this time, the chain plate vacuum suction cup driving mechanism 29 grabs the waste material and drives it to the top of the waste groove 18. The waste material enters the waste groove 18 in the above manner, and finally the cloth collecting roller 17 is started to drive the cloth to move forward, and then the subsequent cutting operation is carried out.

[0034] The vacuum pump 9 generates negative pressure by sucking air, thereby meeting the demand for smoke during cutting and the suction demand of the chain plate vacuum suction cup drive mechanism 29 when grabbing materials. The flow direction of the negative pressure gas can be adjusted by adjusting the air intake three-way valve 12. The CCD camera 50 is set outside the smoke shield 4 to effectively prevent the influence of smoke during cutting on the clarity of the captured image. The filter box 10 is used to filter the smoke.

[0040] Working principle: When in use, first convert the drawing of the product to be cut into a file format that can be recognized by the laser cutting machine and input it into the laser cutting device body 1, drag one end of the tarpaulin through the ion wind rod 6, the rear surface of the second cloth guide roller 16 and the upper surface of the first cloth guide roller 7 in turn, and then place it on the laser cutting workbench 38, and finally wrap the tarpaulin around and fix it on the surface of the cloth collection roller 17, turn on the laser cutting device body 1 for cutting, and the laser cutting device body 1 starts to cut the tarpaulin according to the predetermined path. The laser cutting workbench 38 pushes the drive frame 2 through the drag chain on its rear side, and the drive frame 2 pushes the laser fixing seat 3 through the drag chain on one side. The laser in the laser cutting device body 1 forms a high-power density laser beam, and the laser beam passes through The optical path system transmits and focuses, focusing into a point. When the high-power density laser beam irradiates the surface of the tarpaulin, the surface of the tarpaulin quickly absorbs the laser energy and converts it into heat energy, causing the surface temperature to rise rapidly. When the melting point of the tarpaulin is reached, the tarpaulin begins to melt to form a molten pool, thereby achieving cutting. The laser cutting head 8 moves along a predetermined trajectory along with the laser fixing seat 3, and the laser beam forms a continuous cutting line on the surface of the tarpaulin. While cutting, the turned-on vacuum pump 9 generates negative pressure. At this time, the air intake three-way valve 12 connects the main air intake pipe 11 and the filter box outlet pipe 13. The negative pressure draws the cut smoke into the filter box 10 through the filter box air intake pipe 15, and enters the filter box outlet pipe 13 after being filtered by the filter box 10, and then enters the vacuum pump through the main air intake pipe 11. 9 is discharged, the CCD camera 50 takes a picture of the cut image and sends it to the control unit of the laser cutting device body 1, the control unit analyzes and identifies the image processing algorithm, so as to determine whether the cut pattern is deviated or shifted. When a problem is found, the cutting operation is stopped so that the staff can adjust the fault in time, so as to prevent more unqualified tarpaulin products from being cut. After the cutting operation is completed, the CCD camera 50 observes the position of the cut tarpaulin product and the waste material. After the observation is completed, the driving screw 40 is started according to the position of the tarpaulin product to adjust the position of the electric telescopic cylinder mounting plate 41 of the tarpaulin unloading drive mechanism, and the electric telescopic cylinder mounting plate 41 of the tarpaulin unloading drive mechanism drives the electric telescopic cylinder 21 of the tarpaulin unloading drive mechanism Move horizontally, the electric telescopic cylinder 21 of the tarpaulin unloading drive mechanism drives the drive box 22 to move through the support frame 23, and the drive box 22 drives the drive rod 27 to move horizontally, so that the position of the chain plate vacuum suction cup drive mechanism 29 corresponds to the position of the tarpaulin product. At this time, adjust the air intake three-way valve 12 to connect the main air intake pipe 11 and the vacuum suction cup main suction pipe 14, start the vacuum pump 9, and the negative pressure generated by the vacuum pump 9 allows air to be sucked in from the vacuum suction cup 32, and enter the diverter 44 through the second vacuum suction cup branch suction pipe 33. The diverter 44 merges the air into the first vacuum suction cup branch suction pipe 45, and the air in the first vacuum suction cup branch suction pipe 45 is then merged into the vacuum suction cup main suction pipe 14 through the diverter 44, so that the vacuum suction cup 32 generates negative pressure.The electric telescopic cylinder 21 of the stretching tarpaulin unloading drive mechanism drives the drive box 22 to move downward, allowing the vacuum suction cup 32 to be adsorbed on the upper surface of the tarpaulin product, thereby fixing the tarpaulin product. At this time, the drag chain between the driving frame 2 and the laser cutting workbench 38 is driven to place the vacuum suction cup 32 above the product slot 19. When the tarpaulin product is longer in size, the driving motor 24 can be driven. The driving motor 24 drives the active sprocket 25 to rotate. The active sprocket 25 drives the driven sprocket 26 to rotate through the chain 28. The driven sprocket 26 drives the driving rod 27 to rotate. The driving rod 27 drives the mounting chain plate 31 to roll by driving the first sprocket 35, thereby allowing the vacuum suction cup 32 to rotate. Roll, adjust the on and off of the second vacuum suction cup sub-suction pipe 33 through the second vacuum suction cup sub-suction pipe valve 34, and open the second vacuum suction cup sub-suction pipe valve 34 when the vacuum suction cup 32 moves to the lower end of the chain plate vacuum suction cup drive mechanism 29, and close the second vacuum suction cup sub-suction pipe valve 34 when it leaves the lower end of the chain plate vacuum suction cup drive mechanism 29, thereby dragging the tarpaulin product into the product slot 19. At this time, the chain plate vacuum suction cup drive mechanism 29 grabs the waste material and drives it to the top of the waste slot 18. In the above manner, the waste material enters the waste slot 18, and finally the cloth collecting roller 17 is started to drive the cloth to move forward, and then the subsequent cutting operation is carried out.
