As shown in fig. 17, 18 and 20, length detection devices are further disposed on two sides of the lifting device along a direction perpendicular to the conveying direction of the pipe, and each length detection device includes a first baffle 35.2 disposed on one side of the lifting device, a second baffle 35.1 disposed on the other side of the lifting device, and a servo motor; the servo motor drives the first baffle 35.2 to move towards the second baffle 35.1 along the direction perpendicular to the pipe conveying direction, the servo motor drives the first baffle 35.2 to abut against one end of the pipe, the other end of the pipe abuts against the second baffle 35.1, the length of the pipe is calculated according to the moving distance difference of the servo motor, and the cutting distance of the pipe conveyed to the laser pipe cutting machine is determined according to the length value provided by the servo motor.

when the laser pipe cutting machine needs to process pipes, the pipe storage bin automatically obtains materials according to the type of the pipes needed by the laser pipe cutting machine, the separation motor 33.3 drives the separation chain, so that the separation assembly 33.19 is driven to move along the separation slide rail 33.9, and the distance between the first inclined side 33.19.1 and the parallel surface 33.21.1 is automatically adjusted to be equal to the overall dimension of the pipes; the material blocking motor drives the material blocking chain, so that the material blocking assembly is driven to move along the material blocking slide rail 33.17, and the distance between the bearing surface 33.18.1 and the first inclined side surface 33.19.1 is automatically adjusted to be equal to the external dimension of the pipe; after adjustment is completed, the pipe storage bin sends a bundle of pipes to the material receiving device 32, the pulling motor 33.10 drives the pulling rope assembly 32.2, so that the feeding end of the material receiving frame 32.1 is driven to upwards turn around the discharging end of the material receiving frame 32.1, the bundle of pipes sent from the pipe storage bin is turned to the feeding side of the material distributing device 33, and the material receiving frame 32.1 still keeps an inclined state; a bundle of pipes are stacked on the surfaces of the first inclined side surface 33.19.1, the collision surface 33.21.2 and the material receiving frame 32.1, then the material pushing motor 33.1 drives the material pushing chain, so that the material pushing assembly 33.21 is driven to move upwards along the material pushing slide rail 33.13, as the distance between the first inclined side surface 33.19.1 and the parallel surface 33.21.1 is equal to the overall dimension of the pipes, the collision surface 33.21.2 of the material pushing assembly 33.21 collides with the pipes and can only push the pipes upwards in a single-layer and non-laminated mode, and when the infrared sensor 33.20 detects that one pipe falls onto the material blocking assembly, the infrared sensor sends a signal to control the material pushing motor 33.1 to rotate reversely, so that the material pushing assembly 33.21 retracts to the initial point; then, the first cylinder 34.3 of the measuring device 34 drives the pressing plate 34.1 to move downwards until the pressing surface 34.1.1 is abutted to the surface of the pipe, after the pressing surface 34.1.1 is abutted to the surface of the pipe, the displacement sensor 34.2 is abutted to the surface of the pipe through the through hole of the pressing surface 34.1.1, and the external dimension of the pipe is measured through the difference of the moving amount of the displacement sensor 34.2, so that whether the model of the pipe is the model of the laser pipe cutting machine to be processed or not is judged; if not, the material blocking motor drives the material blocking assembly to slide upwards along the material blocking slide rail 33.17, the pipe is pushed to the material pushing assembly 33.21, and then the pipe is switched; if yes, the material blocking motor drives the material blocking assembly to move downwards along the material blocking slide rail 33.17, when the bearing surface 33.18.1 of the material blocking assembly descends to be lower than the upper surface of the transmission belt 35.12, the upper surface of the transmission belt 35.12 transmits the pipe to the lifting device, the limiting column 35.3 limits the continuous transmission of the pipe, the lifting device drives the lifting device to ascend according to the external dimension of the pipe obtained by the measuring device 34, and the central point of the pipe is ascended to the designated fixed height; the servo motor drives the first baffle 35.2 to abut against one end of the pipe, the other end of the pipe abuts against the second baffle 35.1, the servo motor calculates the length of the pipe according to the difference of the moving distances, and the cutting distance of the pipe conveyed to the laser pipe cutting machine is determined; after the length of the pipe is measured by the servo motor, the conveying motor drives the manipulator to move along the conveying direction of the pipe, the clamping motor drives the upper clamp 35.9 and the lower clamp 35.8 to synchronously clamp in opposite directions, after the pipe is clamped by the manipulator, the lifting motor reversely rotates to drive the lifting device to descend downwards, and the conveying motor continues to drive the manipulator to move along the conveying direction of the pipe until the central point of the pipe coincides with the central point of the clamp of the laser pipe cutting machine; after a front chuck and a rear chuck of the laser pipe cutting machine clamp pipes, a clamping motor reversely drives an upper clamp 35.9 and a lower clamp 35.8 to be separated and opened, a conveying motor reversely drives a manipulator to return to an initial point, and when the laser pipe cutting machine still needs the same type of pipes, the steps are repeated to carry out feeding;

if the laser pipe cutting machine needs another type of pipe, the material pulling motor 33.10 reversely rotates to drive the material pulling frame to return to the initial point; the pipe storage warehouse takes the rest pipes away; the pipe storage bin conveys another type of pipe required by the laser pipe cutting machine to the material receiving device 32; the separating motor 33.3 drives the separating assembly 33.19 to move along the separating slide rail 33.9, the distance between the first inclined side 33.19.1 and the parallel surface 33.21.1 is automatically adjusted to be the external dimension of the pipe, the material stopping motor drives the material stopping assembly to move along the material stopping slide rail 33.17, and the distance between the bearing surface 33.18.1 and the first inclined side 33.19.1 is automatically adjusted to be the external dimension of the pipe; and repeating the steps after the adjustment is finished. When the switching of the pipes is realized, the whole process does not need the participation of operators, the intelligent automation degree is high, and the production cost is reduced; the pipe can be measured, and the type of the pipe can be judged; the material pulling device can feed large-batch pipes, so that the feeding efficiency is improved; the pipe fitting feeding device is suitable for feeding pipes of different types, and is high in applicability.
