Description

Technical Field

[0001] The present invention relates to the technical field of automated laser processing, and in particular to a fully automatic tension laser blanking production line and a production method. Background Art

[0002] With the development of social economy, consumers' demand for personalized and diversified products is increasing. The traditional large-scale production model is gradually changing to multi-variety and small-batch production. In order to reduce production costs and improve production efficiency, enterprises are increasingly inclined to use automated production equipment to replace manual operations. In many industries, such as automobile manufacturing and electronic equipment manufacturing, the quality and precision of parts are increasingly required. Laser blanking technology, with its high-precision and high-quality cutting effect, can meet the strict requirements of these industries for the precision of parts and improve the overall quality and performance of products.

[0003] Although laser cutting technology can process a variety of materials, it is not effective for complex three-dimensional shapes or non-planar, high-reflectivity materials or ultra-thick materials. The high-energy laser beam generated during the laser cutting process poses a serious risk of injury to the human body. If the equipment's protective devices are not perfect or the operator violates regulations, laser radiation may cause burns to the eyes and skin. Laser cutting will produce a large amount of dust, smoke and harmful gases, such as metal dust, ozone, nitrogen oxides, etc., which will harm the working environment and the health of operators.

[0004] Therefore, it is very necessary for the present application to propose a fully automatic tension laser blanking production line and production method to solve the problems in the background.

The above patent realizes a multi-head multi-station step-by-step laser blanking continuous production line, which greatly improves the processing efficiency. However, the above patent cannot control the position accuracy of the blanked parts and the quality of the material stack.

[0006] 2. Patent document CN104648931B discloses a fully automatic laser cutting production line. The above patent achieves a high degree of automation in the production line processing and transportation process, thereby improving work efficiency. However, the above patent cannot realize the laser marking function.

[0007] 3. Patent document CN114850701B discloses an automated production line and method for coil laser cutting. The above patent realizes that the automated production line for coil laser cutting has a small footprint, is highly integrated, saves space, operates automatically, and saves manpower. It greatly improves the degree of automation of the equipment, improves the processing and production efficiency of users, and improves the economic efficiency of users' use of the equipment. However, the above patent cannot maintain the tension and flatness of the steel strip after most contour cutting.

[0008] 4. Patent document CN117324800B discloses a laser cutting production line and production method. The above patent can not only realize the automatic loading, cutting and unloading of sheet materials, but also can automatically sort and collect them according to the different sheets to be cut, with a higher degree of automation and intelligence. However, the above patent cannot realize the precise picking and placing of blanks.

[0009] In summary, the above patents cannot achieve the control of the position accuracy of blanks and the quality of the stack, the laser marking function, the maintenance of the tension and flatness of the steel strip after most contour cutting, and the accurate placement of blanks, resulting in the manual placement position being too large, the vibration displacement of the equipment causing the blanks to shift, the unreasonable spatial layout, and the abnormal deformation of the steel strip, which reduces production efficiency; To this end, the present application proposes a fully automatic tension laser blanking production line and production method that can achieve control of the position accuracy of blanking parts and the quality of the material stack, laser marking function, maintain the tension and flatness of the steel strip after most contour cutting, and accurately pick up and place blanking parts.

DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , an embodiment provided by the present invention: a fully automatic tension laser blanking production line, the production method comprising the following steps: S1, the steel coil is unrolled and threaded through the unwinding station 8, and after being straightened by the leveling machine 7, it enters the tension laser cutting machine 5 through the feeder 6; S2, the tension laser cutting machine 5 completes the cutting of the lengthwise contour of the blank. While completing most of the contour cutting, the support roller 42 and the pressure roller 41 still maintain the tension and flatness of the steel strip through friction, and the steel strip continues to be fed to the telescopic support laser cutting machine 3; S3. Before further cutting, the end picker 43 of the manipulator first sucks the blank using vacuum negative pressure, and then the cutting head 38 cuts off the blank from both ends. The two cutting heads 38 move to both sides, and the manipulator takes away the blank; S4, the waste is cut and enters the waste box 1; S11, when the steel strip is threaded, the crossbeam R9 and crossbeam F10 of the tension laser cutting machine 5 are parked at the upstream berth. Driven by the feeder 6, the steel strip passes through the support clamping roller of the crossbeam R9. The crossbeam R9 clamps the material head and works in conjunction with the feeder 6 to thread the strip downstream. At the same time, the crossbeam F10 starts cutting. At this time, only one crossbeam can be used for cutting to reduce the waste of the material head. After the crossbeam R9 reaches the downstream berth, the steel strip continues to pass through the tension machine 4 and the downstream equipment, and the crossbeam R9 starts to participate in cutting; S21, when processing the tail of steel strip, the crossbeam F10 stops cutting and moves to the upstream berth. The clamping roller of the crossbeam F10 clamps the tail of the strip and moves downstream with the tail of the strip. The crossbeam R9 continues cutting to make full use of the tail of the strip. S22, the dust suction port 35 moves along with the cutting head 38, and the cutting waste falls into the waste box 40; S31, robot RB128 picks up the blanks, while robot RB229 palletizes the blanks on palletizing table PT326. After robot RB128 finishes picking up, it palletizes the blanks on palletizing table PT124, while robot RB229 picks up the blanks; S32, after the palletizing platform 19 is fully loaded, it moves from the palletizing station to the unloading station, and the robot switches to the palletizing platform 19 waiting at the palletizing station for palletizing, and the palletizing platform 19 that completes unloading moves to the palletizing station in time; Furthermore, the model 1 blanking line is set as the economical configuration, the model 2 blanking line is set as the standard configuration, the model 3 blanking line is set as the advanced configuration, and the model 4 blanking line is set as the flagship configuration. The flagship configuration is under the standard configuration, and the four cutting heads F1, F2, R1 and R2 are enhanced. The two enhanced cutting heads are installed on the same beam, which can ensure nearly 2 times the cutting efficiency. The number of these cutting heads can be reduced according to customer needs. The system automatically optimizes the distribution of the cutting volume of all cutting heads to ensure the highest cutting efficiency. The steel coil is placed on the uncoiling station 8 for uncoiling operation and the threading process is completed at the same time. The steel strip is then straightened by the leveling machine 7 to ensure the flatness of the steel strip when entering the subsequent process. The straightened steel strip enters the tension laser cutting machine 5 under the push of the feeder 6. After entering the tension laser cutting machine 5, the support roller 42 and the pressure roller 41 work together to maintain the tension and flatness of the steel strip through the friction between them and the steel strip. Even when most of the contour cutting is completed, the steel strip can still continue to feed under appropriate tension until it enters the telescopic support laser cutting machine 3. When the steel strip arrives at the telescopic support laser cutting machine 3 and is ready for further cutting, the end picker 43 of the manipulator uses vacuum negative pressure to tightly suck the blank, and then the cutting head 38 cuts off the blank from both ends. After the cutting is completed, the two cutting heads 38 quickly move to the sides, and the robot smoothly takes away the blanks to prepare for the subsequent stacking operation. The cut waste is cut off in step S4 and smoothly enters the waste box 1 through the waste conveying channel to avoid waste accumulation on the production line; During the steel strip threading stage, the beams R9 and F10 of the tension cutting machine are parked at the upstream berth according to the predetermined procedure. Driven by the feeder 6, the steel strip slowly passes through the support clamping rollers of the beam R9. At this time, the beam R9 accurately clamps the material head and works in conjunction with the feeder 6 to start threading downstream. During this period, the beam F10 starts the cutting operation, but due to the particularity of the threading process, only one beam is used for cutting at this time, which can effectively reduce the waste of the material head. When the beam R9 successfully reaches the downstream berth, the steel strip continues to pass through the tension machine 4 and other downstream equipment. At this time, the beam R9 joins the cutting operation sequence and works in coordination with the beam F10, and the tension laser cutting machine 5 enters a full cutting state; In the palletizing process of blanking parts, robot RB128 first picks up blanking parts, while robot RB229 performs palletizing operations on palletizing table PT326. When robot RB128 completes the picking task, it will accurately palletize the blanking parts on palletizing table PT124, while robot RB229 immediately performs the picking operation of blanking parts. This cycle is repeated to achieve efficient rotation operation, which greatly improves the palletizing efficiency. When palletizing table 19 is fully loaded, palletizing table 19 will automatically move from the palletizing station to the unloading station. At this time, the robot will quickly switch to other palletizing stations 19 in standby state at the palletizing station to continue the palletizing operation. After the unloading is completed, the palletizing station 19 that has completed unloading will promptly move back to the palletizing station to wait for the next round of palletizing tasks. When processing steel strip tailings, in order to make full use of the material, the beam F10 stops cutting and moves to the upstream berth. Its clamping roller accurately clamps the tail of the material and then moves downstream with the tail of the material. During this period, the beam R9 continues to cut the steel strip tailings to cut them into usable blanks as much as possible to reduce the waste of raw materials. During the entire cutting process, the dust suction port 35 always follows the movement of the cutting head 38, and the waste slag falls into the waste slag box 40. The waste slag box 40 is designed to be easy to clean. Regular cleaning of the waste slag box can ensure the continuous and efficient operation of the dust suction system, maintain the cleanliness of the production line, and reduce the impact of waste slag on equipment and production environment.

The operator faces the side of the blanking line, the right is the X direction, the forward is the Y direction, and the upward is the Z direction. The coordinate system adapts to the operator's habits and has nothing to do with the running direction of the production line; the telescopic support laser cutting machine 3, tension machine 4, tension laser cutting machine 5, feeder 6, leveler 7 and unwinding station 8 in the blanking line are all set with independent local coordinate systems, and the control system and industrial software of the blanking line use the same custom coordinate system; The end of the servo motor push rod of the telescopic support laser cutting machine 3 is fixedly mounted on the shaft of the pressure roller 41 through a connector, the pressure roller 41 is located above the material, a support roller 42 is arranged below the material, the bottom end of the outer wall of the support roller 42 is fixedly mounted on the bearing seat, and the bottom end of the outer wall of the bearing seat is fixedly mounted on the frame of the telescopic support laser cutting machine 3; The palletizing station 2 is provided with a truss 30 as a supporting structure, a manipulator is fixedly installed on the top of the outer wall of the truss 30, an end picker 43 is fixedly installed on the end of the manipulator, the end picker 43 uses the vacuum principle to absorb the blanks, and the manipulator is operated by a robot control system; Furthermore, the uncoiling station 8 is provided with an uncoiling machine, and a guide plate is fixedly installed at the front end of the uncoiling machine. The rolled steel strip is installed on the uncoiling station 8. The uncoiling station 8 is started, and the steel strip is slowly unrolled and conveyed to the leveling machine 7. The leveling machine 7 is started to level the metal sheet sent from the uncoiling station 8. The leveling machine 7 applies appropriate pressure and friction to the sheet through multiple sets of rollers to eliminate the bending, wave and other deformations of the sheet produced during the winding process, so that the sheet meets the specified flatness requirements; the sheet after leveling enters the feeder 6, and the feeder 6 stably conveys the sheet to the position of the tension laser cutting machine 5. During this process, the control system of the blanking line accurately controls the feeding position and direction of the feeder 6 through the PLC according to the set coordinate origin and the custom coordinate system. When it is necessary to cut blanks of specific shapes and sizes, the control system calculates the precise coordinate point to which the feeder 6 should convey the sheet according to the design position of the blank in the coordinate system, so that the sheet is in the best cutting starting position when entering the tension laser cutting machine 5; When the plate reaches the area of ​​the tension laser cutting machine 5, the tension machine 4 starts to work, and the servo motor push rod in the tension machine 4 pushes the pressure roller 41 downward, so that the pressure roller 41 cooperates with the support roller 42 located under the material to apply a certain tension to the plate. For a stainless steel plate with a thickness of 2mm, the tension value is set to 5000N according to the process requirements. Through the precise control of the tension machine 4, the plate always maintains a stable tension state during the cutting process to avoid affecting the cutting accuracy and quality due to the relaxation or excessive stretching of the plate. The tension laser cutting machine 5 starts, and the laser cutting head, under the command of the control system, cuts the plate along the set cutting path to cut out blanks of the required shape and size. During the cutting process, due to the stable tension provided by the tension machine 4, the cutting process is smoother, the cutting edge is smoother and neater, and defects such as cutting burrs and deformation are effectively reduced; For some blanks that need secondary cutting or special processing, after the plate is cut by the tension laser cutting machine 5, some blanks are transported to the position of the telescopic support laser cutting machine 3. The servo motor push rod of the telescopic support laser cutting machine 3 adjusts the position and pressure of the pressure roller 41 to reposition and support the plate. Then, the laser cutting head performs secondary fine cutting or special shape processing on the blanks, further improving the processing accuracy and quality of the blanks. The manipulator installed on the top of the truss 30 drives the end picker 43 at the end to move above the blanks under the control of the robot control system. The end picker 43 uses the vacuum principle to generate a strong adsorption force to firmly adsorb the blanks. Then, the manipulator accurately places the blanks at the designated position on the palletizing station 2 according to the pre-set palletizing program and palletizes them in a certain arrangement.

[0027] The scraps of the cut edges automatically fall into the waste box 1 located below the outer wall side of the stacking station 2.

According to the position of the cutting head 38 and the change of the cutting area, it flexibly moves on the X guide rail 37 and the Y guide rail 36, and always stays in the vicinity of the cutting dust generation area to ensure the maximum dust suction. The generated dust is sucked into the dust suction port 35, and some heavier waste particles fall into the waste box 40 for collection. The dust-containing gas sucked in by the dust suction port 35 is transported to the subsequent dust removal equipment through the telescopic air pipe 39 for further purification, so that the discharged gas meets the environmental emission standards, effectively protecting the environment of the production workshop and the health of the operators; The cut plates are transported by two truss-type palletizing robots, which place the cut plates accurately on four palletizing platforms 19 according to a preset program for classification and palletizing.

The gantry moves along the custom coordinate axis through the control system and the motor drive; Further, the metal sheet to be processed is uncoiled through the uncoiling station 8, and is leveled by the leveling machine 7 and transported by the feeder 6 to the working area of ​​the tension laser cutting machine 5; Under the command of the control system, the plate is laser cut along the custom coordinate axis. The cutting heads F117 and F218 start cutting from one side of the plate first, and perform fine cutting along the predetermined contour path. The cutting speed is set to 10m / min according to the material and thickness of the plate, and the laser power is adjusted to 2000W. At the same time, the cutting heads R115 and R216 cooperate to cut from the other side of the plate. The collaborative operation of multiple cutting heads improves cutting efficiency and shortens cutting time. During the cutting process, if the control system detects that the roughness of the cutting surface increases during the cutting process, the control system automatically fine-tunes the laser power or cutting speed through the sensor to restore the roughness of the cutting surface to the specified range; Then the blanks that have been processed or specially shaped are transported to the area of ​​the telescopic support laser cutting machine 3 through belt drive after being cut by the tension laser cutting machine 5. The cutting head S14 performs micro-processing on the edge to remove tiny burrs or perform chamfering. The cutting head T13 performs fine cutting on the special shape structure inside. In this process, the tension of the plate is also kept stable by the tension machine 4, and the servo motor push rod of the telescopic support laser cutting machine 3 flexibly adjusts the position and pressure of the pressure roller 41 to provide precise support and positioning for the plate. Driven by the control system and motor, the gantry at both ends of the outer wall of the marking head K46 moves along the custom coordinate axis to the top of the plate, and makes clear and lasting marks on the surface of the plate. The laser power is set to 500W and the marking speed is 50mm / s. The focused laser beam ablates a mark with a depth of 0.1mm on the surface of the plate. After marking, the relevant information of the blank can be traced by scanning and reading the mark content.

[0030] See also Figure 1 , Figure 3 and Figure 5 , an embodiment provided by the present invention: a fully automatic tension laser blanking production line, the stacking station 2 is provided with a stacking station, a stacking platform 19, a robot and a discharge station, the top of the outer wall of the truss 30 is fixedly provided with a robot RB128 and a robot RB229, the top of the outer wall of the stacking platform 19 is fixedly installed with a robot, the top of the outer wall of the stacking station and the discharge station is fixedly installed with a stacking platform 19, and the side of the outer wall of the stacking station is fixedly installed with a discharge station; The stacking station is provided with a stacking station PC120, a stacking station PC221, a stacking station PC322 and a stacking station PC423. A discharge station UC131 is fixedly installed at one end of the side of the outer wall of the stacking station PC120, a stacking station PC221 is fixedly installed at the other end of the side of the outer wall of the stacking station PC120, a discharge station UC232 is fixedly installed at one end of the side of the outer wall of the stacking station PC221, a stacking platform PT225 is fixedly installed at the top of the outer wall of the discharge station UC232, and a stacking platform PT124 is provided at the bottom of the outer wall of the stacking station PC120; A discharge station UC333 is fixedly installed at one end of the outer wall side of the stacking station PC322, a stacking station PC423 is fixedly installed at the other end of the outer wall side of the stacking station PC322, a discharge station UC434 is fixedly installed at one end of the outer wall side of the stacking station PC423, and a stacking platform PT427 is fixedly installed at the top of the outer wall of the discharge station UC434; Furthermore, the robot RB128 first receives the command from the control system and goes to receive the blanks delivered from the tension laser cutting machine 5 or the telescopic support laser cutting machine 3. The end picker at the end of its mechanical arm uses the vacuum adsorption function to firmly grasp the blanks, and the robot RB128 moves the grasped blanks to the top of the stacking station PC120. If the stacking station PC120 is empty and meets the placement conditions, the robot RB128 will accurately place the blanks on the stacking table PT124, and the edge of the blanks will be aligned with the positioning mark of the stacking table PT124; When the blanks on the palletizing station PC120 reach the preset full stack quantity or weight, the robot RB128 suspends the palletizing operation to the palletizing station PC120, and instead assists in transferring the full stack of blanks on the palletizing table PT124 to the unloading station UC131. While the robot RB128 assists the unloading station UC131, the robot RB229 grabs the blanks from the conveying device, and places the blanks on the palletizing table PT225 on the palletizing station PC221 according to the palletizing strategy. When the unloading station UC131 completes the processing of the full stack of blanks at the palletizing station PC120, the robot RB128 switches its work target and starts palletizing to the palletizing station PC322, while the robot RB229 continues to palletize at the palletizing station PC221. When the palletizing station PC221 is full, the unloading station UC232 performs the unloading operation.

[0031] Working principle: first, the steel coil is unrolled and threaded at the unwinding station 8, and then straightened by the leveling machine 7 and pushed into the tension laser cutting machine 5 by the feeder 6. In the tension laser cutting machine 5, the tension and flatness of the steel strip are maintained by the friction force of the support roller 42 and the pressure roller 41. After cutting, the steel strip continues to be fed to the telescopic support laser cutting machine 3. Before further cutting, the robot end picker 43 at the telescopic support laser cutting machine 3 uses vacuum negative pressure to absorb the blanks, and then the cutting head 38 cuts off the blanks from both ends. The cutting head 38 then moves to both sides, and the robot takes away the blanks, and the waste is cut off and enters the waste box 1.

[0032] During the steel strip threading stage, the beams R9 and F10 of the tension laser cutting machine 5 are first moored at the upstream berth. Driven by the feeder 6, the steel strip passes through the supporting clamping roller of the beam R9. The beam R9 clamps the material head and works with the feeder 6 to thread the strip downstream. At this time, the beam F10 starts cutting but only one beam is used to reduce the waste of the material head. When the beam R9 reaches the downstream berth, the steel strip continues to pass through to the tension machine 4 and other downstream equipment. At this time, the beam R9 also starts to participate in the cutting.

[0033] In the palletizing process, robots RB128 and RB229 work together. While robot RB128 picks up the blanks, robot RB229 palletizes the blanks on palletizing table PT326. Then robot RB128 palletizes the blanks on palletizing table PT124, while robot RB229 picks up the blanks. This cycle continues. When palletizing table 19 is fully loaded, it moves from the palletizing station to the unloading station, and the robot switches to palletizing table 19 on standby at the palletizing station to continue palletizing. After unloading, palletizing table 19 moves back to the palletizing station in time.

[0034] When processing the tailings of the steel strip, the crossbeam F10 stops cutting and moves to the upstream berth, and its clamping roller clamps the tailings and moves downstream with the tailings, while the crossbeam R9 continues cutting to make full use of the tailings. During the entire cutting process, the dust suction port 35 of the two-axis servo dust removal system moves with the cutting head 38, so that the cutting waste falls into the waste box 40. The waste box 40 is a drawer type for easy cleaning, and the dust suction port 35 is driven by a two-axis servo motor, and can be accurately positioned in the plane formed by the X guide rail 37 and the Y guide rail 36. In addition, the marking head K46 on the crossbeam K45 of the tension laser cutting machine 5 can move along the custom coordinate axis under the drive of the gantry, control system and motor to mark the blanks.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
