[0024] Thanks to the above technical solutions, the present application has at least the following technical effects:

[0025] 1. In the present application, the three-dimensional storage device provides pre-storage and pipe scheduling functions for the pipe workpieces to be processed. Before the production line operates, a corresponding number of pipe workpieces to be processed can be pre-stored in all pipe storage structures. The pipe storage structures are placed in pipe storage stations, so that the lifting mechanism can drive the stacking mechanism to lift and schedule the pipe storage structures from the pipe storage stations to the material discharge stations one by one, so as to provide the material taking device with a source of pipe acquisition. When the pipe in a pipe storage structure is taken out in the material discharge station and becomes empty, the pipe storage structure can be reset from the material discharge station to the original pipe storage station by the stacking mechanism and the lifting mechanism, and then the pipe storage structure storing the pipe workpieces to be processed can be scheduled from other pipe storage stations. All pipe storage stations are arranged in the vertical direction of the three-dimensional frame in sequence. Compared with horizontal arrangement, the vertical arrangement makes the three-dimensional frame store a large number of pipe workpieces to be processed in the height direction on the basis of a small floor area. Therefore, after a single replenishment of material to all pipe storage structures, the production line can realize long-time unattended automatic operation. The taking guide rail provides a running track for the moving part to circulate between the material taking station and the material unloading station, so that the moving part can drive the material taking part to take the pipe workpieces to be processed from the pipe storage structure and then unload the pipe workpieces to the pipe positioning mechanism. The pipe positioning mechanism carries the pipe workpieces to be processed to the cutting station, and the pipe workpieces to be processed are cut into finished pipe workpieces meeting the requirements by the laser cutting head according to the preset program. Therefore, the production line provided by the present application realizes pre-storage of pipe workpieces to be processed, automatic scheduling of the pipe workpieces by the lifting mechanism and the stacking mechanism, automatic transfer of the pipe workpieces from the three-dimensional storage device to the laser cutting device by the material taking device, and automatic cutting of the pipe workpieces after reaching the laser cutting device. The production line realizes a multi-process unattended automatic production mode, the cutting system and the production line intelligent scheduling control system are deeply integrated and controlled, the production plan is automatically scheduled and distributed, the laser cutting device is automatically fed without interruption, the production efficiency and management efficiency are greatly improved, the number and cost of labor are reduced, the safety performance is higher, and the product quality and homogeneity of the same specification pipe workpieces can be effectively guaranteed.

[0026] 2. The stacking mechanism can transfer the pipe storage structure from the pipe storage station to the transfer station and then to the buffer platform, and the transfer mechanism can transfer the pipe storage structure from the buffer platform to the feeding platform. This mechanism is suitable for feeding the empty pipe storage structure. Therefore, through the cooperation of the lifting mechanism, the stacking mechanism and the transfer mechanism, the empty pipe storage structure in the pipe storage station can be dispatched to the feeding platform. The pipe workpiece to be processed can be supplemented into the pipe storage structure in the feeding platform, greatly improving the convenience of pipe raw material supplement. After the pipe supplement is completed, the pipe storage structure can be reset to the original pipe storage station through the cooperation of the lifting mechanism, the stacking mechanism and the transfer mechanism, realizing one-key warehousing.

[0027] 3. The taking component includes a first mechanical hand and a second mechanical hand. The first mechanical hand is vertically slidably arranged at one end of the moving component, and the second mechanical hand is horizontally slidably arranged along the moving component and vertically slidably arranged relative to the moving component. First, the first mechanical hand and the second mechanical hand can move in the vertical direction, and the two can cooperate to clamp and obtain the pipe at different heights of the pipe storage structure, so that the taking component can obtain the pipe to be processed one by one from high to low. Second, the second mechanical hand can horizontally slide along the moving component, and the horizontal distance between the first mechanical hand and the second mechanical hand can be changed during the sliding process. Therefore, by horizontally sliding the second mechanical hand, the distance between the first mechanical hand and the second mechanical hand can be adjusted to a distance suitable for the length of the pipe, improving the adaptability to pipes of different length specifications.

[0028] 4. The moving component drives the taking component to move from the taking station to the detection station. After the taking component obtains the pipe to be processed from the pipe storage structure in the taking station, the moving component can drive the taking component to move to the detection station. At this time, the camera component can take a picture of the pipe to be processed to obtain the structure information of the pipe to be processed and transmit the structure information to the control unit. After obtaining the relevant structure information, the control unit can analyze it through a corresponding algorithm to obtain the contour size and phase relationship of the pipe to be processed, and transmit the final execution command to the taking device and the laser cutting device, so that the taking device automatically adjusts the clamping force of the first mechanical hand and the second mechanical hand on the pipe, and the laser cutting device automatically adjusts the clamping force of the pipe positioning mechanism and the unloading structure on the pipe, so that the clamping force is adapted to the thickness of the pipe, preventing the pipe from being deformed due to excessive clamping force. The laser cutting device can also automatically retrieve the cutting process library to realize automatic cutting.

[0029] 5. The laser cutting device can automatically unload and automatically sort the pipe after cutting through the unloading structure. Short pipes are unloaded onto the short material receiving plate, and long pipes are unloaded onto the long material receiving plate, facilitating the division and management of finished pipes.

[0030] 6. The sorting and palletizing device collects and organizes short pipes that fall from the short receiving plate through the dropping chute, and collects and organizes long pipes that fall from the long receiving plate through the dropping platform. The sorting mechanism is used to count the long pipes on the dropping platform and transfer them to another preset position, realizing automated sorting, transfer and palletizing, and improving management efficiency and production efficiency.

[0031] 7. The production line also includes a transport track and material transport trolleys that can move back and forth on the transport track. Finished pipes sorted by the sorting mechanism can be stacked into the material transport trolleys. After stacking to a specified quantity, the material transport trolleys are transported to a designated warehouse location via the transport track or returned to the finished product layer in the three-dimensional storage device via the return-to-warehouse function.

[0032] 8. The coding device is used to code the finished pipes after laser cutting, which can facilitate product management, effectively improve economic benefits, and can be connected to the enterprise network system to achieve network management and unattended operation.

Specifically, the pipe clamped by the pipe taking member 33 can be placed on the supporting member 231 and supported by the supporting member 231, and then the pipe taking member 33 can be moved away from the unloading station. The first chuck 232 and the second chuck 233 are adjusted to clamp the two ends of the pipe, and then moved to the cutting station along the pipe conveying rail 22.

The pipe unloading structure 26 unloads the short pipe which is less than or equal to a preset length to the short pipe taking plate 24 at the first unloading station. The pipe unloading structure 26 unloads the long pipe which is greater than the preset length to the long pipe taking plate 25 at the second unloading station.

The third chuck 261 and the fourth chuck 262 are used to clamp the finished pipe cut by the laser cutting head 21 and move to the first unloading station or the second unloading station according to the length of the finished pipe. For example, when the preset length is 1.5 meters, the finished pipe cut by the laser cutting head 21 is less than or equal to 1.5 meters in length, the pipe unloading structure 26 is moved to the first unloading station and the finished pipe is placed on the short pipe taking plate 24.

The sorting cross beams 533 are movable on the sorting rails 532 in the horizontal plane, so as to transfer the long pipe materials attracted by the electromagnets 535 to the preset position. Specifically, the sorting cross beams 533 drive the sorting shafts 534 to move during movement on the sorting rails 532. When the sorting shafts 534 are above the long pipe materials on the material falling platform 52, the sorting shafts 534 are controlled to move downward and the electromagnets 535 are powered to generate an attractive force, so that the long pipe materials can be attracted to the electromagnets 535. Then, the sorting shafts 534 are controlled to move upward, and the long pipe materials are transferred to above the preset position by movement of the sorting cross beams 533 on the sorting rails 532. Then, the long pipe materials can fall from the electromagnets 535 to the designated position after the electromagnets 535 are powered off. Of course, the sorting shafts 534 can also be controlled to move downward again to slowly place the long pipe materials to the designated position after the long pipe materials are transferred to above the preset position, so as to avoid collision and damage of the long pipe materials due to free fall.
