[0003] In actual processing and manufacturing, since the purchased pipes are generally relatively long, they need to be cut into sections according to the designed length. Considering the requirement for the flatness of the cut, a laser pipe cutting machine is generally selected for cutting. Currently, the related equipment mainly uses a small trailer to drag the long pipe, and the laser pipe cutting machine does not move. The small trailer drives the long pipe to move towards the laser cutting head of the laser pipe cutting machine to adjust the cutting length. With the concepts of "unattended", "autonomous production", "intelligent factory", etc. sweeping the laser industry, the demand for automated production in the laser pipe cutting machine market is booming. However, the existing laser pipe cutting equipment cannot achieve unattended automated production for the entire process. Especially in the feeding stage, most workers need to send the metal pipes into the pipe fixtures and transport the pipes forward in each cutting cycle. In this way, the production is not continuous, time-consuming and laborious, and the production efficiency is low. Summary of the Utility Model

[0039] In an embodiment of the present application, a laser cutting production line is provided. For the convenience of description and understanding, the following content provided by the present application is all elaborated on the basis of the illustrated product structure. Of course, those skilled in the art can understand that the above structure is only a specific example and schematic description, and does not constitute a specific limitation on the technical solution provided by the present application.

[0040] As Figures 1 to 4As shown in the figure, a laser cutting production line provided by the present application includes a storage table 1, at least one laser pipe cutting machine 2, a material taking device, and a pipe detection device 4. Among them, the storage table 1 is used to store pipes to be processed, the laser pipe cutting machine 2 is used to perform laser cutting operations on the pipes, the material taking device includes a material taking guide rail 31, a moving component 32, and a material taking component 33. The material taking component 33 is arranged on the moving component 32. The moving component 32 can move back and forth along the material taking guide rail 31 to drive the material taking component 33 to take out the pipe from the storage table 1 and then unload the pipe to the laser pipe cutting machine 2. The pipe detection device 4 includes a camera component. The camera component can capture images of the pipes located on the storage table 1 and the pipes taken out by the material taking component 33 to obtain the structural information and placement attitude information of the pipes, and transmit the structural information and the placement attitude information to the control unit of the laser cutting production line, so that the control unit controls the material taking device and the laser pipe cutting machine 2 to perform actions according to the structural information and the placement attitude information.

[0041] In the laser cutting production line provided in this application, the storage table 1 provides a pre-storage function for the pipes to be processed. Before the production line operates, a corresponding number of pipes to be processed can be pre-stored in the storage table 1. The material taking device can transfer the pipes to be processed stored in the storage table 1 to the laser pipe cutting machine 2 one by one, so that the laser pipe cutting machine 2 can laser cut the pipes to be processed. Specifically, the material taking guide rail 31 is the running track for the reciprocating movement of the moving part 32, so that the moving part 32 can drive the material taking part 33 to obtain the pipes to be processed from the storage table 1 and then unload the pipes to be processed to the laser pipe cutting machine 2, waiting for the laser pipe cutting machine 2 to perform the laser cutting action on the pipes. Therefore, the production line of this application realizes the automatic transfer of the pipes from the storage table 1 to the laser pipe cutting machine 2 through the material taking device, eliminating the step of manually loading the laser pipe cutting machine 2 and saving manpower. In addition, the imaging component can take pictures of the pipes to be processed to obtain the structural information and placement attitude information of the pipes to be processed and transmit the structural information to the control unit. After obtaining the structural information and placement attitude information of the pipes, the control unit can analyze them through corresponding algorithms to obtain the contour dimensions, phase relationships, and placement postures of the pipes to be processed, and transmit the final execution command to the material taking device and the laser pipe cutting machine 2, so that the material taking device and the laser pipe cutting machine 2 perform actions. For example, it can control the material taking device and the laser pipe cutting machine 2 to automatically adjust the clamping force on the pipes to make the clamping force adapt to the pipe thickness, prevent the pipes from being crushed and deformed due to excessive clamping force, and can also control the laser pipe cutting machine 2 to automatically retrieve the cutting process library adapted to the pipe information to achieve automatic cutting, effectively ensuring the quality of the processed finished pipes and the homogeneity of the processing of pipes of the same specification. During specific processing, the imaging component can take pictures of the pipes to be processed stacked and placed on the storage table 1 to obtain the phase relationship, structural information, and placement attitude information of each pipe, so that the control unit controls the material taking device to take materials one by one according to the phase relationship according to the algorithm program, and controls the laser pipe cutting machine 2 to automatically retrieve the cutting process library adapted to the structural information and placement attitude information of the pipes. When the pipes are taken out from the storage table 1 by the material taking part 33, the attitude may change, especially for special-shaped pipes, whose attitude is easy to change after being taken out. At this time, the imaging component can take pictures of the taken-out pipes again to re-obtain their structural information and placement attitude information, so as to more accurately control the laser pipe cutting machine 2 to retrieve the cutting process library adapted to the pipes. The number of laser pipe cutting machines 2 in this application is not limited. For example, Figure 1 An embodiment in which two laser pipe cutting machines 2 are arranged side by side is schematically shown. The two laser pipe cutting machines 2 can work simultaneously to achieve multi-machine parallel connection. A single material taking device can take care of the feeding tasks of multiple laser pipe cutting machines 2, support the feeding of multiple types of pipes to the designated laser pipe cutting machine 2, and improve production efficiency.

[0042] As a preferred embodiment of this application, as Figure 2As shown, the imaging component is configured as an industrial camera 41. The pipe detection device 4 further includes a supplementary lighting component 42, which can provide supplementary lighting to the pipes located on the storage table 1 and the pipes taken out by the material taking component 33. Those skilled in the art can understand that, compared with traditional civilian cameras (video cameras), the industrial camera 41 has high image stability, high transmission ability, high anti-interference ability, etc. The performance of the industrial camera 41 is stable and reliable, easy to install, the camera structure is compact and strong, not easily damaged, has a long continuous working time, and can be used in a relatively poor environment. Moreover, the shutter time of the industrial camera 41 is very short, which can capture fast-moving objects and also has a high frame rate. When the industrial camera 41 cannot clearly obtain pipe-related information due to too dark light, the supplementary lighting component 42 can be used for supplementary lighting to improve the imaging clarity of the industrial camera 41. The supplementary lighting component 42 can be a light source panel or other lighting devices.

[0043] As a preferred embodiment of the present application, as Figure 1 and Figure 4 shown, a plurality of vertical rods 11 extending in the vertical direction are provided on two opposite sides of the storage table 1. The vertical rods 11 enclose a storage space for storing pipes to stop and limit the pipes within the storage space. After the pipes are stacked on the storage table 1 in sequence, the pipes are limited within the storage space by the vertical rods 11, which can effectively prevent the pipes from rolling off the storage table 1. Moreover, under the limitation of the vertical rods 11, more pipes can be stacked on one storage table 1, improving the storage capacity of the storage table 1.

[0044] As a preferred embodiment of the present application, as Figure 1 、 Figure 2 and Figure 3As shown, the material taking guide rail 31 extends between the storage table 1 and the laser pipe cutting machine 2. The moving member 32 is configured as a moving cross beam perpendicular to the material taking guide rail 31. The material taking member 33 includes a first material taking part 331 and a second material taking part 332. The first material taking part 331 is arranged at one end of the moving member 32, and the second material taking part 332 can move along the length direction of the moving cross beam. The first material taking part 331 and the second material taking part 332 respectively act on two ends of the pipe to take out the pipe from the storage table 1. Specifically, two material taking guide rails 31 can be arranged side by side, and two ends of the moving cross beam are respectively connected to the two material taking guide rails 31. Preferably, sliders can be arranged on the moving cross beam, and slide rails are arranged on the material taking guide rails 31. The moving cross beam is guided to move back and forth along the material taking guide rail 31 through the cooperation of the sliders and the slide rails. The first material taking part 331 is arranged at one end of the moving cross beam, and the second material taking part 332 can move along the length direction of the moving cross beam, and its horizontal distance from the first material taking part 331 changes during the movement. Therefore, by moving the second material taking part 332, the distance between the first material taking part 331 and the second material taking part 332 can be adjusted to a distance adapted to the length of the pipe, so as to realize the clamping of pipes with different lengths and improve the adaptability to pipes with different length specifications.

[0045] Furthermore, as Figure 2 and Figure 3 shown, the first material taking part 331 includes a first vertical guide rod 3311, a first manipulator and a second driving module 3312. The second driving module 3312 is used to drive the first manipulator to move up and down along the first vertical guide rod 3311. And the second material taking part 332 includes a second vertical guide rod 3321, a second manipulator and a third driving module 3322. The third driving module 3322 is used to drive the second manipulator to move up and down along the second vertical guide rod 3321. The first manipulator and the second manipulator respectively clamp two ends of the pipe to take out the pipe from the storage table 1. The first manipulator and the second manipulator respectively realize the up and down movement in the vertical direction under the drive of the second driving module 3312 and the third driving module 3322. The cooperation of the two can clamp pipes at different heights stacked on the storage table 1, so that the material taking member 33 can successively obtain the pipes to be processed from high to low, and the pipe scheduling and transfer are orderly and reasonable. The structures of the first driving module and the second driving module 3312 in this application are not limited. In a preferred embodiment, the first driving module and the second driving module 3312 can both be composed of a motor, a transmission gear driven by the motor and a transmission rack meshed with the transmission gear. The motor can be arranged on the first manipulator and the second manipulator, and the transmission rack is vertically arranged on the first vertical guide rod 3311 and the second vertical guide rod 3321. When the motor runs, the first manipulator and the second manipulator are driven to move up and down through the meshing transmission of the transmission gear and the transmission rack.

[0046] The specific structure of the first manipulator and the second manipulator is not specifically limited in this application. In a preferred embodiment, the first manipulator includes a first cylinder and a first pin connected to the piston rod of the first cylinder, and the second manipulator includes a second cylinder and a second pin connected to the piston rod of the second cylinder. The first cylinder and the second cylinder can respectively drive the first pin and the second pin to insert into the two ends of the pipe. It can be understood by those skilled in the art that the middle of the pipe is a hollow structure that runs through both ends. Therefore, the first cylinder and the second cylinder can respectively drive the first pin and the second pin to insert into the two ends of the pipe, so that the pipe can be lifted up from the storage platform 1. Under the restriction of the first pin and the second pin, the pipe will not fall off from the first manipulator and the second manipulator. In other embodiments, the first manipulator and the second manipulator can also use electromagnets to adsorb or release the pipe by switching the on and off states of the electromagnets.

[0047] As a preferred embodiment of the present application, Figure 1 and Figure 3 As shown, the moving part 32 is driven by the first driving module to realize reciprocating movement along the material taking guide rail 31, and the first driving module includes a driving motor 34 provided on the moving part 32, a reducer 35 connected to the output shaft of the driving motor 34, a gear 36 drivingly connected to the reducer 35, and a rack 37 provided on the material taking guide rail 31. When the driving motor 34 is running, the gear 36 and the rack 37 are meshed and driven to make the moving part 32 reciprocate along the material taking guide rail 31. For the above-mentioned embodiment of arranging two material taking guide rails 31 side by side, a gear 36 can be connected to each end of the reducer 35, and a rack 37 can be provided on each material taking guide rail 31.

[0048] As a preferred implementation of the present application, Figure 1 As shown, each of the laser tube cutting machines 2 includes a laser cutting head 21, a material transport guide rail 22 and a tube positioning mechanism. The tube positioning mechanism is used to receive the tubes unloaded by the material taking component 33. The tube positioning mechanism can move along the material transport guide rail 22 to transfer the tubes to the laser cutting head 21 for laser cutting. The material taking component 33 obtains the tubes to be processed from the material storage platform 1 and then unloads the tubes to be processed onto the tube positioning mechanism, so that the tube positioning mechanism carries the tubes to be processed to the laser cutting head 21. The tubes to be processed are cut into finished tubes that meet the requirements according to a preset program by the laser cutting head 21, so that the tubes can be automatically transported and cut from the material storage platform 1 to the laser cutting head 21, and the automatic production is realized.

[0049] Furthermore, if Figure 1As shown in the figure, the pipe positioning mechanism includes a supporting member 231, a first chuck 232, and a second chuck 233. The supporting member 231 is used to support the pipe unloaded by the material taking member 33. After the first chuck 232 and the second chuck 233 clamp the two ends of the pipe, they move along the material conveying guide rail 22 to transfer the pipe to the laser cutting head 21. Specifically, the distance between the first chuck 232 and the second chuck 233 can be pre-adjusted to be greater than the length of the pipe. The pipe clamped by the material taking member 33 can be pre-placed on the supporting member 231 and positioned by the supporting member 231. At this time, the pipe is located between the first chuck 232 and the second chuck 233. The material taking member 33 can reset to retrieve the next pipe from the storage table 1. At the same time, the first chuck 232 and the second chuck 233 shorten the distance to clamp the pipe at both ends, and then move the pipe along the material conveying guide rail 22 to the laser cutting head 21.

[0050] As a preferred embodiment of the present application, as Figure 1 and Figure 4 shown in the figure, the production line further includes a three-dimensional frame 5. The three-dimensional frame 5 is provided with storage bins arranged in sequence along the vertical direction. The storage table 1 can enter and exit the storage bins and provide pipes for the material taking device in the state of being moved out of the storage bins. The three-dimensional frame 5 can provide pre-storage and pipe scheduling functions for the pipe workpieces to be processed. Before the production line operates, the corresponding number of pipes to be processed can be pre-stored in all the storage tables 1 corresponding to the number of storage bins. The storage tables 1 are placed in the storage bins. Specifically, the storage bins can be scheduled to enter and exit the storage bins through devices such as lifting mechanisms and stacking mechanisms. Whenever the pipes in a storage table 1 moved out of the storage bin are used up by the material taking device, it can be re-adjusted back into the storage bin to wait for the replenishment of the pipes to be processed. All the storage bins are arranged in sequence along the vertical direction of the three-dimensional frame 5. Compared with the horizontal arrangement, the vertical arrangement enables the three-dimensional frame 5 to store a large number of pipes to be processed by using the space in the height direction on the basis of a small floor area. Therefore, after a single replenishment of materials to all the storage tables 1, the production line can achieve unattended automated operation for a long time. In addition, multiple storage bins can also be used to classify and store pipes, and pipes to be processed of different specifications can be distributed in different storage bins, which is convenient for management and reduces the management and operation costs.
