[0046] In order to illustrate the technical solutions described in the present application, the following will be described in detail with reference to specific drawings and embodiments.

[0047] See Figure 1 、 Figure 2 、 Figure 4 and Figure 8 As shown in one or more embodiments, the present application provides a laser pipe cutting system, which includes: a loading mechanism 101, a loading centering mechanism 102, a loading chuck mechanism 103, a laser cutting mechanism 104, a unloading chuck mechanism 105, a unloading handling mechanism 106 and a unloading buffer mechanism 107; the loading mechanism 101 is used for conveying the pipes to be cut, and the loading mechanism 101 includes a plurality of loading chain sub-parts 108, see Figure 11As shown, a plurality of feeding chain sub-parts 108 are distributed at intervals in the first direction. The plurality of feeding chain sub-parts 108 are linked by a first transmission shaft 109 in a dynamic manner. The axial direction of the first transmission shaft 109 is parallel to the first direction. The feeding centering mechanism 102 is used to clamp the pipe to be cut conveyed by the feeding mechanism 101. The feeding centering mechanism 102 includes a sub-centering mechanism 110. The sub-centering mechanism 110 includes a jaw unit 111, a first lifting unit 112 and a first transverse movement unit 113. The jaw unit 111 is used to clamp the pipe to be cut. The first lifting unit 112 is used to drive the jaw unit 111 to perform a lifting movement. The first transverse movement unit 113 is used to drive the first lifting unit 112 to move in the second direction. The first direction is perpendicular to the second direction. The feeding chuck mechanism 103 is used to clamp the pipe to be cut conveyed by the feeding centering mechanism 102. The laser cutting mechanism 104 is used to cut the pipe to be cut clamped by the feeding chuck mechanism 103. The unloading chuck mechanism 105 is used to clamp the cut pipe. The unloading handling mechanism 106 is used to handle the cut pipe clamped by the unloading chuck mechanism 105. The unloading handling mechanism 106 includes a support platform 114, a second lifting unit 115 and a second transverse movement unit 116. The support platform 114 is used to carry the cut pipe. The second lifting unit 115 is used to drive the support platform 114 to perform a lifting movement. The second transverse movement unit 116 is used to drive the second lifting unit 115 to move in the second direction. The unloading buffer mechanism 107 is used to buffer the cut pipe handled by the unloading handling mechanism 106.

[0048] In at least one embodiment of the present application, the laser pipe cutting system is provided with a feeding mechanism 101 to facilitate the individual feeding of the pipes to be cut. The feeding centering mechanism 102 can perform actions such as clamping, lifting and translation on the pipes to be cut on the feeding mechanism 101, so that the pipes to be cut leave the feeding mechanism 101 and are conveyed to the feeding chuck mechanism 103. The feeding centering mechanism 102 can accurately adjust the spatial position of the pipes to be cut, so as to facilitate the centering of the feeding chuck mechanism 103 and the pipes to be cut, simplifying the centering operation. After the laser cutting mechanism 104 cuts the pipes to be cut, the unloading chuck mechanism 105 and the unloading handling mechanism are used to convey the cut pipes to the unloading buffer mechanism 107, so that the unloading buffer mechanism 107 can temporarily store the cut pipes, thus simplifying the loading and unloading of the pipes and being beneficial to saving time.

[0049] In the embodiment of the present application, for the convenience of description, the first direction is the X-X direction and the second direction is the Y-Y direction.

[0050] In some embodiments, the laser pipe cutting system can cut pipes within 12 meters (including 12 meters). The number of the loading chain sub-parts 108 can be 2, 3, 4, 5, 6, etc., and can be specifically determined according to the length of the heavy pipes to be conveyed. The use of multiple loading chain sub-parts 108 can better support and convey the pipes; the number of the first drive shafts 109 can be multiple, and adjacent two loading chain sub-parts 108 are connected through the first drive shaft 109. In this way, by driving one of the first drive shafts 109, the movement of multiple loading chain sub-parts 108 can be realized, which is conducive to realizing the synchronous movement of multiple loading chain sub-parts 108.

[0051] Combined with Figure 2 and Figure 3 As shown, in some embodiments, the loading mechanism 101 further includes a first motor 117; the loading chain sub-part 108 includes a loading bracket 118, a first chain 119, and a first sprocket 120; the first sprocket 120 is installed on the loading bracket 118, the first chain 119 is engaged with the first sprocket 120, the first drive shaft 109 is fixedly connected to the first sprocket 120, and the first motor 117 is used to drive the first drive shaft 109 to rotate. The use of the first chain 119 and the first sprocket 120 can facilitate the transportation of the pipe material to be cut. Exemplarily, the first sprocket 120 can be installed on the loading bracket 118 through a bearing seat, so as to realize the rotation of the first sprocket 120 relative to the loading bracket 118, and the first drive shaft 109 and the first sprocket 120 can be connected through a coupling. The number of the first sprockets 120 can be two, and the two first sprockets 120 are spaced apart along the second direction, and the first drive shaft 109 is connected to one of the first sprockets 120 in the loading chain sub-part 108. A chain plate 121 can also be fixed on the first chain 119, and the pipe material to be cut is limited in the second direction through the chain plate 121, so that the pipe material to be cut can move with the movement of the first chain 119. The chain plate 121 includes a bottom plate 122 and a vertical plate 123, the bottom plate 122 is fixedly connected to the first chain plate 121, the vertical plate 123 is fixedly connected to the bottom plate 122, and a clamping groove 124 is formed between the two vertical plates 123 on the two chain plates 121, and the pipe plate to be cut is limited in the clamping groove 124.

[0052] See Figure 4 and Figure 12As shown, in some embodiments, the jaw unit 111 includes a jaw slide rail 125, a jaw rod 126, and a jaw cylinder; there are two jaw sliders 127 on the guide rail of the jaw slide rail 125, and a jaw rod 126 is fixed on each jaw slider 127. The jaw rod 126 can be installed on the jaw slider 127 through a bearing, and the jaw rod 126 can rotate around its own axis; a rack 129 is fixed on each of the two jaw sliders 127, and a gear 128 is arranged between the two racks 129. The gear 128 meshes with the two racks 129 respectively. The gear 128 is rotatably installed on the guide rail of the jaw slide rail 125; the cylinder block of the jaw cylinder is fixedly connected to the guide rail of the jaw slide rail 125, and one end of the piston rod of the jaw cylinder is fixedly connected to one of the jaw sliders 127. In this way, when the piston rod of the jaw cylinder expands and contracts, the two racks 129 can move under the action of the gear 128, so that the distance between the two jaw rods 126 of the two jaw sliders 127 can increase or decrease, thereby realizing the clamping or loosening of the pipe to be cut.

[0053] See Figure 4 and Figure 12 As shown, in some embodiments, the first lifting unit 112 includes a first linear slide rail 130 and a first driving device. The jaw unit 111 is installed on the slider of the first linear slide rail 130. The first driving device is used to drive the slider of the first linear slide rail 130 to move in the vertical direction. The first driving device can include a third motor 131, a gear 128, and a rack 129. The rack 129 is fixed on the slider of the first linear slide rail 130, and the gear 128 is installed on the output shaft of the third motor 131. In this way, the third motor 131 drives the gear 128 to rotate, and the gear 128 moves the rack 129, thereby realizing the up and down movement of the slider of the first linear slide rail 130, and then realizing the lifting of the jaw unit 111. It can be understood that the first lifting unit 112 can also be an electric slide table, a hydraulic cylinder or a cylinder.

[0054] In some embodiments, the first transverse movement unit 113 can be an electric slide table, a hydraulic cylinder or a cylinder, and the first transverse movement unit 113 is used to realize the linear movement of the first lifting unit 112.

[0055] See ​ and ​As shown, in some embodiments, the loading and centering mechanism 102 further includes an auxiliary support mechanism 132. The auxiliary support mechanism 132 includes a bearing unit 133, a third lifting unit 134, and a third transverse movement unit 135. The bearing unit 133 includes a first support frame 136 and a plurality of first rollers 137 arranged side by side; the first rollers 137 are installed on the first support frame 136. The third lifting unit 134 is used to drive the bearing unit 133 to move up and down, and the third transverse movement unit 135 is used to drive the third lifting unit 134 to move in the second direction. The auxiliary support mechanism 132 can be used to support the pipe to be cut. Exemplarily, the first support frame 136 is in the form of a plate structure, and the third lifting unit 134 is in the form of an electric slide rail. The first support frame 136 is installed on the slider of the electric slide rail, so as to realize the lifting movement of the first support frame 136. The number of the first rollers 137 can be two. The axial direction of the first roller 137 is parallel to the second direction; the bearing unit 133 further includes two triangular brackets 138. The two triangular brackets 138 are distributed at intervals. The triangular brackets 138 are fixed to the first support frame 136. The two ends of the first roller 137 are respectively rotatably connected to the two triangular brackets 138 through bearings, so as to realize the rotation of the first roller 137 relative to the triangular brackets 138, and the first roller 137 can rotate around its own axis. It can be understood that the third lifting unit 134 can also adopt the same structural form as the first lifting unit 112.

[0056] In some embodiments, the third transverse movement unit 135 can be an electric slide table, a hydraulic cylinder or a cylinder, and the second transverse movement unit 116 is used to realize the linear movement of the third lifting unit 134.

[0057] In some embodiments, the number of the auxiliary support mechanisms 132 is multiple, and the number of the sub-centering mechanisms 110 is multiple. The multiple auxiliary support mechanisms 132 and the multiple sub-centering mechanisms 110 are alternately distributed in the first direction. Exemplarily, the auxiliary support mechanism 132 and the sub-centering mechanism 110 are located between two adjacent sub-parts 108 of the loading chain. The number of the auxiliary support mechanisms 132 is two, and the number of the sub-centering mechanisms 110 is three. The auxiliary support mechanism 132 is located between two adjacent sub-centering mechanisms 110.

[0058] In some embodiments, the sub-centering mechanism 110, the auxiliary support mechanism 132, and the pipe to be cut located on the sub-loading chain section 108 can be on the same straight line. In this way, the sub-centering mechanism 110 can clamp, lift, and translate the pipe to be cut on the loading chain section 108. At the same time, the auxiliary support mechanism 132 can lift and translate the pipe to be cut on the loading chain section 108 and move along the second direction in cooperation with the sub-centering mechanism 110 to move the pipe to be cut to the loading chuck mechanism 103. When the loading mechanism 101 conveys the pipe to be cut to the set position, the first lifting unit 112 of the sub-centering mechanism 110 raises the jaw unit 111. At the same time, the third lifting unit 134 of the auxiliary support mechanism 132 raises the bearing unit 133, so that the pipe to be cut on the loading mechanism 101 is disengaged from the loading mechanism 101. Then, the jaw unit 111 of the sub-centering mechanism 110 clamps the pipe to be cut to ensure the centering between the pipe to be cut and the loading chuck mechanism 103, that is, to ensure coaxiality.

[0059] See ​As shown, in some embodiments, the laser pipe cutting system further includes a main bracket 139. The loading chuck mechanism 103 includes a first chuck 140 and a second chuck 141, and the first chuck 140 and the second chuck 141 are mounted on the main bracket 139. The first chuck 140 and the second chuck 141 can be used to clamp and translate the pipe to be cut. The first chuck 140 serves as the main loading chuck, while the second chuck 141 serves as the intermediate chuck. The first chuck 140 and the second chuck 141 are slidably mounted on the main bracket 139. For example, linear sliding rails are mounted on the main bracket 139, and the first chuck 140 and the second chuck 141 are mounted on the sliders of the linear sliding rails. The driving of the linear sliding rails can be achieved by the cooperation of nuts, lead screws, and motors to move the sliders, or by hydraulic cylinders to achieve the movement of the sliders, so as to enable the first chuck 140 and the second chuck 141 to move along the first direction on the main bracket 139. When the sub-centering mechanism 110 of the loading centering mechanism 102 and the auxiliary support mechanism 132 together transport the pipe to be cut between the first chuck 140 and the second chuck 141, the first lifting unit 112 and the third lifting unit 134 make the height position and the position in the second direction of the pipe to be cut satisfy the coaxiality of the pipe to be cut with the first chuck 140 and the second chuck 141 respectively. In this way, when the first chuck 140 and the second chuck 141 move towards each other, the clamping of the pipe to be cut can be achieved. Then the jaw unit 111 is loosened, the first lifting unit 112 and the third lifting unit descend, and under the drive of the respective first transverse movement units 113 and third transverse movement units 135, they move to the initial position to wait for corresponding operations on another pipe to be cut on the loading mechanism 101. It should be noted that the first chuck 140 clamps and fixes one end of the pipe to be cut, while the second chuck 141 only supports the pipe to be cut, and the pipe to be cut can move relative to the second chuck 141, that is, the pipe to be cut can move along its own axial direction relative to the second chuck 141. The first chuck 140 moves to push the pipe to be cut to move, so that the pipe to be cut moves towards the direction close to the laser cutting mechanism 104, facilitating the cutting of the pipe to be cut.

[0060] See ​ and ​As shown, in some embodiments, the laser pipe cutting system further includes an auxiliary support 143. The auxiliary support 143 includes a support body 144 and a second roller 145. The second roller 145 is installed on the support body 144 and can rotate relative to the support body 144. The second roller 145 is used to support the drag chain 146 on the cable of the first chuck 140, so as to realize the support of the drag chain 146. Since the first chuck 140 needs to move, in order to protect the cable on the first chuck 140, a drag chain 146 is installed on the cable. In this way, when the cable moves with the first chuck 140, the drag chain 146 can protect the cable. When the first chuck 140 moves, a part of the structure of the drag chain 146 is supported by the second roller 145 of the auxiliary support 143, so the collapse of the drag chain 146 can be prevented, ensuring the stability of the connection between the cable and the electrical components on the first chuck 140.

[0061] See ​ and ​ As shown, in some embodiments, the laser cutting mechanism 104 includes a laser cutting head 147, a fourth lifting unit 148 and a fourth transverse movement unit 149. The fourth lifting unit 148 is used to drive the laser cutting head 147 to move up and down, and the fourth transverse movement unit 149 is used to drive the fourth lifting unit 148 to move along the second direction. In this way, the movement of the laser cutting head 147 in three-dimensional space is realized to cut the pipe to be cut. Exemplarily, the laser cutting mechanism 104 further includes a protective cover 152 to protect the laser cutting head 147. Both the fourth lifting unit 148 and the fourth transverse movement unit 149 can adopt electric slide rails, which facilitates the movement of the laser cutting head 147.

[0062] See ​As shown, in some embodiments, the blanking chuck mechanism 105 includes a third chuck 150 and a fourth chuck 151, and the third chuck 150 and the fourth chuck 151 are mounted on the main bracket 139. The third chuck 150 serves as an auxiliary chuck and has the same function as the second chuck 141. The fourth chuck 151 serves as a blanking chuck and has the same function as the first chuck 140. Exemplarily, the third chuck 150 and the fourth chuck 151 are mounted on different sliders of a linear slide. The linear slide can be driven by a nut, a lead screw, and a motor to achieve slider movement, or by a hydraulic cylinder or a cylinder to achieve slider movement, thereby enabling the third chuck 150 and the fourth chuck 151 to move along the first direction on the main bracket 139. It should be noted that the fourth chuck 151 clamps and fixes one end of the cut tube, while the third chuck 150 only supports the cut tube. The cut tube can move relative to the third chuck 150, that is, the cut tube can move along its own axial direction relative to the third chuck 150. The fourth chuck 151 moves to pull the cut tube to move, so that the cut tube moves away from the laser cutting mechanism 104, so as to facilitate the cutting operation of the cut tube.

[0063] In some embodiments, the support platform 114 is a plate-like structure, which facilitates supporting the cut pipe. It should be noted that the surface of the support platform 114 for supporting the cut pipe can be provided with two protrusions spaced apart. The two protrusions serve to limit the cut pipe in the second direction, thereby preventing the cut pipe from falling off the surface of the support platform 114.

[0064] In some embodiments, the second lifting unit 115 can employ the same structure as the first lifting unit 112. For details, please refer to the description of the structure of the first lifting unit 112. It is understood that the second lifting unit 115 can also be in the form of an electric slide. The second traverse unit 116 can employ the same structure as the first traverse unit 113. For details, please refer to the description of the structure of the first traverse unit 113. Of course, the first traverse unit 113 can also be an electric slide, hydraulic cylinder, or pneumatic cylinder.

[0065] See also ​ As shown, in some embodiments, the blanking buffer mechanism 107 includes a plurality of blanking chain sub-sections 153, which are spaced apart along a first direction and are rotatably linked by a second transmission shaft 154, the axial direction of the second transmission shaft 154 being parallel to the first direction. The blanking buffer mechanism 107 can temporarily store cut pipes.

[0066] In some embodiments, the number of the blanking chain sub - parts 153 can be 2, 3, 4, 5, 6, etc., and specifically can be determined according to the length of the heavy - duty pipe to be conveyed. Using multiple blanking chain sub - parts 153 can better support and convey the pipes; the number of the second drive shafts 154 can be multiple, and adjacent two blanking chain sub - parts 153 are connected by the second drive shafts 154. In this way, by driving one of the second drive shafts 154, the movement of multiple blanking chain sub - parts 153 can be realized, which is beneficial to realizing the synchronous movement of multiple blanking chain sub - parts 153.

[0067] See ​ 、 ​ and ​ As shown in, in some embodiments, the blanking buffer mechanism 107 further includes a second motor 155; the blanking chain sub - part 153 includes a blanking support 156, a second chain 157 and a second sprocket 158; the second sprocket 158 is installed on the blanking support 156, the second chain 157 is engaged with the second sprocket 158, the second drive shaft 154 is fixedly connected with the second sprocket 158, and the second motor 155 is used to drive the second drive shaft 154 to rotate. Using the second chain 157 and the second sprocket 158 can conveniently realize the transportation of the cut pipe material. Exemplarily, the second sprocket 158 can be installed on the blanking support 156 through a bearing seat, so as to realize the rotation of the second sprocket 158 relative to the blanking support 156, and the second drive shaft 154 and the second sprocket 158 can be connected through a coupling. The number of the second sprockets 158 can be three, and the three second sprockets 158 are spaced along the second direction. One of the second sprockets 158 is located between the other two second sprockets 158, and the second drive shaft 154 is connected to the middle second sprocket 158 in the blanking chain sub - part 153. The middle second sprocket 158 also serves as a tensioner for the second chain 157. In the second direction, one of the second sprockets 158 on the blanking chain sub - part 153 is close to the main support 139, and the other second sprocket 158 is far from the main support 139. A stop baffle 159 is fixed at one end of the blanking support 156 in the length direction away from the main support 139. Using the stop baffle 159 can prevent the cut pipe from falling off the blanking chain sub - part 153, so as to realize the temporary storage of the cut pipe on the blanking chain sub - part 153.

[0068] In some embodiments, the cut pipe on the support platform 114 of the blanking handling mechanism 106 can be moved above the blanking chain sub - unit 153, which facilitates the transportation of the cut pipe by the blanking chain sub - unit 153. The second transverse movement unit 116 and the second lifting unit 115 cooperate to make the support platform 114 located directly below the cut pipe clamped between the third chuck 150 and the fourth chuck 151. After the cut pipe is supported by the support platform 114, the third chuck 150 and the fourth chuck 151 are moved away from the cut pipe. Then, the second transverse movement unit 116 drives the cut pipe to move in the second direction to move above the blanking chain sub - unit 153. Finally, after the second lifting unit 115 descends a certain height, the cut pipe leaves the support platform 114 and is supported by the second chain 157 on the blanking chain sub - unit 153. Through the movement of the second chain 157, the cut pipe is driven to move in the second direction away from the main body bracket.

[0069] The above are only optional embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
