Description

Technical Field

[0001] This invention relates to the field of laser cross-cutting machine technology, specifically a multi-head collaborative high-speed laser cross-cutting machine. Background Technology

[0002] As the core material for electrical equipment such as transformers and motors, the processing precision of silicon steel sheets directly affects the energy consumption and operational stability of the equipment. With the increasing demands for high efficiency and energy saving in the electrical industry, the thickness of silicon steel sheets is gradually moving towards 0.18mm or even thinner, which places higher demands on its cutting and processing equipment.

[0003] Currently, the cutting of silicon steel plates generally adopts mechanical cutting and stamping process. This process requires each cutting station to be equipped with a separate stamping tool and matching anvil. The cutting process path is fixed when the equipment leaves the factory, and the processing status can only be adjusted by activating or deactivating the station. The shape of the tool determines the cutting characteristics, and it is impossible to complete diverse cutting shapes. When changing products, it is often necessary to replace the entire set of tools or even the equipment, which results in high adaptation costs and long cycles. Summary of the Invention

[0004] The technical problem to be solved by this invention is that traditional mechanical cutting and stamping can only cut silicon steel plates into a single shape and the process is fixed. This invention provides a multi-head collaborative high-speed laser cross-cutting machine.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a laser cross-cutting machine includes a laser assembly and a conveying assembly;

[0006] The laser assembly includes multiple cutting mechanisms, a receiving mechanism, and a support mechanism. The bottom of each cutting mechanism is equipped with a support mechanism, and a receiving mechanism is located on one side of each cutting mechanism.

[0007] The conveying assembly includes a feeding mechanism and a guiding mechanism, which are connected front and rear to each other;

[0008] The cutting mechanism is connected to the guiding mechanism on the side away from the receiving mechanism;

[0009] The cutting mechanism includes a main laser cutting machine, a main three-axis module, and nozzles. The main laser cutting machine is located on the main three-axis module, and a secondary laser cutting machine is located on one side of the main laser cutting machine. Both the main laser cutting machine and the secondary laser cutting machine are equipped with nozzles. The nozzles are used to cover the high-temperature laser spot with high-pressure nitrogen gas for cooling.

[0010] The laser assembly performs multiple shape cuts on silicon steel sheets according to requirements. Its cutting mechanism is used to cut each feature of the silicon steel sheet, the receiving mechanism is used to collect the cut sheet, the feeding assembly is used to place the silicon steel coil and control the rotation of the silicon steel coil to achieve unwinding. The unwound silicon steel sheet is placed on the guide assembly, and the double-sided centering mechanism then centers and corrects the moving silicon steel sheet and constrains its movement. During the cutting process, the high-pressure airflow generated by the nozzle comes into contact with the high-temperature spot generated by the laser head, thereby fully cooling the cut area. Due to the inertness of nitrogen, it does not interact with the high-temperature spot generated by the laser head, which not only achieves faster cooling performance but also completely washes away the burrs generated during cutting.

[0011] Furthermore, the support mechanism includes a support platform, with rack and pinion motion mechanisms on both sides of the support platform. A moving platform is located inside the rack and pinion motion mechanisms, which can automatically adjust its position so that the main laser machine for cutting circles is suspended below to facilitate waste removal. A top surface adsorption mechanism is located between the moving platforms. The top surface adsorption mechanism is used to adsorb silicon steel material through the current position. Due to the need for rapid material removal, the support mechanism is set above the silicon steel plate to facilitate direct waste removal after cutting, without waiting for waste removal to be completed before proceeding to the next action. A secondary three-axis module is located on one side of the top surface adsorption mechanism.

[0012] The rack and pinion motion mechanism is equipped with a main three-axis module, the moving ends of which are all connected to the main laser cutting machine, and the moving ends of the auxiliary three-axis module are equipped with auxiliary laser cutting machines.

[0013] A receiving mechanism is provided on one side of the support platform, and a guiding mechanism is provided on the side of the support platform away from the receiving mechanism.

[0014] The support platform surface is equipped with a rack and pinion motion mechanism, which is parallel to the central axis of the support platform. This mechanism controls the axial movement of the main three-axis module. Since the main laser cutting machine is connected to the main three-axis module, the movement of the main three-axis module drives the main laser cutting machine to move, thus enabling simultaneous cutting of three features of different lengths and shapes. The main three-axis module adjusts the position of the main laser cutting machine at its moving end through independent drive modules in the X, Y, and Z directions. Several main three-axis modules and main laser cutting machines are provided, each with a main laser... The cutting machines operate independently, cutting silicon steel sheets according to their settings. A separate auxiliary three-axis module and auxiliary laser cutting machine are used for the final cutting of the silicon steel sheet, transforming the long strip into the desired silicon steel sheet material. During the cutting process, there are two cutting methods depending on the length of the material. The first method, for shorter materials, designates the silicon steel sheet cut by the auxiliary laser cutting head as the first sheet, while the main laser cutting head adjacent to the auxiliary laser cutting head performs a V-shaped notch cut, designating this section as the second sheet. Due to the circular hole position of the short material... If the processing positions of the circular holes and V-shaped notches are too close together, interference and collision of the cutting heads will occur if they are processed simultaneously on the same sheet. Therefore, the two laser cutting heads responsible for the circular hole cutting process are set on the third sheet. By processing the sheets in a staggered manner, the risk of cutting head interference is avoided, ensuring the safety and stability of the cutting operation. For longer materials, the silicon steel sheet cut by the secondary laser cutting head is set as the first sheet, and the silicon steel sheet with the V-shaped notch cut by the main laser cutting head adjacent to the secondary laser cutting head is set as the second sheet. Since the processing positions of the circular holes and V-shaped notches of the long material are far apart, the space conditions for multiple heads to work simultaneously are met. Therefore, the other main laser cutting heads are controlled to simultaneously complete the circular hole cutting of the second sheet, and the last main laser cutting head processes the circular hole on the right side of the third sheet. This design can complete the circular hole cutting and V-shaped notch cutting on the same sheet, effectively shortening the structural layout length of the circular hole cutting area, while reducing the frequency error of the stepping feed and improving the relative positional accuracy of each cutting feature on the same sheet.

[0015] Furthermore, the feeding mechanism includes an uncoiler and a bending guide plate. The bottom end of the bending guide plate is provided with a mounting frame, and the two sides of the mounting frame are provided with straight guide plates. One end of the straight guide plate is rotatably connected to the mounting frame, and the bottom end of the straight guide plate is provided with a cylinder. The uncoiler is located at the end of the mounting frame away from the guiding mechanism.

[0016] The fixed end of the cylinder is rotatably connected to the mounting bracket, and the output end of the cylinder is rotatably connected to the bottom end of the linear guide plate.

[0017] The uncoiler is an existing technology used to place silicon steel coils and unwind them stably. The sheet material conveyed by the uncoiler is an unprocessed strip sheet. During manual feeding, a cylinder acts as a power source to control the linear guide plate to drive the transport roller group to a horizontal state, so that the linear guide plate forms a plane for fast transport of the strip sheet. When manual feeding is completed, the cylinder acts as a power source to control the linear guide plate to reset, thereby driving the transport roller group to fit against the curved guide plate in an arc state, guiding the silicon steel sheet into the buffer area in a U-shape. In the uncoiling state, the strip sheet is sent out from the uncoiler and enters and exits the buffer area in a U-shaped posture.

[0018] Furthermore, the curved guide plate surface is equipped with a set of transport rollers.

[0019] The transport roller assembly consists of multiple rollers. During feeding, the straight guide plates are parallel to each other, and the transport roller assembly is arranged on the surface of the straight guide plates. At this time, the transport roller assembly is parallel to the horizontal axis. After feeding is completed, when buffering and storing the strip silicon steel sheet, the straight guide plates are retracted, and the transport roller assembly is arranged on the curved guide plates. At this time, the space between adjacent curved guide plates is a buffer area. When the uncoiler continuously feeds material and the drive mechanism is in a paused cutting state, the excess silicon steel sheet will be temporarily stored in the buffer area. When the drive mechanism resumes feeding, the buffer area gradually releases the stored silicon steel sheet to avoid material accumulation due to fast uncoiling and slow feeding, or material being stretched and deformed due to slow uncoiling and fast feeding, thus ensuring that the silicon steel sheet conveying process is always stable.

[0020] Furthermore, the guiding mechanism includes a double-sided centering module, with a drive mechanism located between one side of the double-sided centering module;

[0021] Both the bilateral centering module and the drive mechanism are located on the surface of the support platform;

[0022] The drive mechanism works in conjunction with the main laser cutting machine.

[0023] After passing through the conveyor roller group, the silicon steel sheet passes through the double-sided centering module and moves to the drive mechanism. The drive mechanism limits the height of the strip silicon steel sheet, and the guide mechanism is used to limit the silicon steel sheet. The bottom inner side of the double-sided centering module is provided with a limiting stop, which contacts the long sides of the silicon steel sheet on both sides to maintain continuous contact with the silicon steel sheet without restricting its continuous movement. The drive mechanism acts as a power source to move the silicon steel sheet, and the feed efficiency is adjusted according to the cutting time of the main laser cutting machine.

[0024] Furthermore, there are several bilateral centering modules, and a limiting stop is provided on the side facing adjacent bilateral centering modules.

[0025] The inner side of the limiting stop edge maintains a slight contact with the edge of the silicon steel plate, which can limit the lateral displacement of the silicon steel plate in real time, prevent the silicon steel plate from deviating to the sides, ensure that the material is always conveyed in a straight line to the drive mechanism and the core cutting mechanism, suppress the tendency of thin material edges to curl up, and avoid material jamming or slippage when entering the drive roller or driven roller, ensuring the continuity of the entire conveying chain. The silicon steel plate is fed into the cutting station through the limiting stop edge. The cross-cutting machine automatically allocates the cutting process according to the length of the material. The three main laser cutting machines are automatically arranged to the cutting position, and the auxiliary laser cutting machine automatically moves to the cutting station according to the cutting position. The three main laser cutting machines and the auxiliary laser cutting machine perform cutting operations simultaneously. Through step feeding, the drive mechanism feeds one piece of material per step and sends it to the receiving mechanism.

[0026] Furthermore, the receiving mechanism includes a connecting seat and a movable flap. The movable flap is located inside the connecting seat and is rotatably connected to the inner wall of the connecting seat. A cylinder is provided on one side of the connecting seat, and multiple conveyor belts are provided on the side of the connecting seat away from the cutting mechanism. The multiple conveyor belts are arranged at an incline.

[0027] The fixed end of the cylinder is connected to the outer wall of the connecting seat, and the output end of the cylinder is connected to the movable flap.

[0028] The connecting seat, as the main supporting component of the receiving mechanism, forms a material conveying channel inside, receiving finished silicon steel sheets from the cutting mechanism. The movable flap is hinged to the inner wall of the connecting seat via a rotating shaft, forming a rotatable guide structure. Its rotatable action is controlled by a cylinder. When the cylinder piston rod extends or retracts, it drives the movable flap to rotate around the hinge point, thereby adjusting the conveying guide path of the material in the connecting seat and ensuring that the finished sheet accurately enters the subsequent conveyor belt structure. Multiple conveyor belts arranged on the side of the connecting seat away from the cutting mechanism are arranged at an angle, and the angles of the multiple conveyor belts are also different, resulting in different transport positions. Because the cutting process is to cut alternately, the trapezoidal silicon steel sheets are arranged alternately at equal intervals. When passing through the connecting seat, the movable flap rotates continuously. When the movable flap flips upward, the silicon steel sheets move to the higher conveyor belt; when the movable flap flips downward, the silicon steel sheets move to the lower conveyor belt, realizing the separate collection of the two different arrangements of silicon steel sheets.

[0029] Furthermore, each conveyor belt has a receiving frame on the side away from the connecting seat, a lifting module is installed inside the receiving frame, and a receiving trolley is installed between the lifting modules.

[0030] The receiving frame, as the load-bearing component at the end of the receiving mechanism, precisely connects with the discharge end of the inclined conveyor belt. The inside of the frame forms a channel adapted to the operation of the receiving trolley, ensuring that the trolley remains stable during lifting and lowering.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. This invention adopts a layout of multiple independent three-axis modules driving laser cutting heads. Each cutting head can independently complete diverse feature cutting such as circular, V-shaped, and beveled cuts according to processing requirements, breaking the process limitation of traditional mechanical cutters that cut one shape at a time, and greatly shortening the process debugging cycle of new products.

[0033] 2. This invention replaces the traditional mechanical stamping process with laser non-contact processing. At the same time, the energy density of laser cutting can be flexibly adjusted according to the thickness of the sheet material. It can not only stably process existing thin material specifications, but also meet the future needs of processing thinner silicon steel sheets.

[0034] 3. This invention innovatively adds a high-pressure nitrogen nozzle to the laser cutting head. Utilizing the inert properties of nitrogen, it isolates oxygen from the high-temperature cutting area during the cutting and cooling process, thus fundamentally avoiding defects such as burrs and deformation caused by oxidation reactions. High-pressure nitrogen-assisted cutting can improve cutting precision to the micron level, and the cut surface is smooth and flat, requiring no subsequent grinding. Attached Figure Description

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example: Figures 1-10 As shown, the present invention provides a technical solution for a multi-head collaborative high-speed laser cross-cutting machine, which includes a laser component 1 and a conveying component 2;

[0048] The laser assembly 1 includes multiple cutting mechanisms 11, a receiving mechanism 12 and a support mechanism 13. The bottom of the multiple cutting mechanisms 11 is provided with a support mechanism 13, and the receiving mechanism 12 is provided on one side of the cutting mechanism 11.

[0049] The conveying assembly 2 includes a feeding mechanism 21 and a guiding mechanism 22, which are connected.

[0050] The side of the cutting mechanism 11 away from the receiving mechanism 12 works in conjunction with the guiding mechanism 22;

[0051] The cutting mechanism 11 includes a main laser cutter 118, a main three-axis module 113, and nozzles 114. The main laser cutter 118 is located on the main three-axis module 113. A secondary laser cutter 117 is provided on one side of the main laser cutter 118. Both the main laser cutter 118 and the secondary laser cutter 117 are provided with several nozzles 114. The nozzles 114 are used to cover the high-temperature laser spot with high-pressure nitrogen gas for cooling.

[0052] like Figure 1As shown, specifically, the laser component 1 is used to cut silicon steel plates in multiple shapes according to requirements, the cutting mechanism 11 is used to cut silicon plates on the rack and pinion mechanism 132, the receiving mechanism 12 is used to collect the cut plates, the feeding component is used to place silicon steel coils and control the rotation of silicon steel coils to achieve unwinding, and the extracted silicon steel plates are placed on the guide component to center the moving silicon steel plates and control their movement. The high-pressure airflow generated by the nozzle 114 will come into contact with the high-temperature spot generated by the laser head, thereby fully cooling the cut area. Due to the inertness of nitrogen, it will not interact with the high-temperature spot generated by the laser head, which not only achieves faster cooling performance, but also completely washes away the burrs generated during cutting.

[0053] The support mechanism 13 includes a support platform 131, rack and pinion motion mechanisms 132 are provided on both sides of the support platform 131, a moving platform 135 is provided inside the rack and pinion motion mechanism 132, a top surface adsorption mechanism 133 is provided on one side of the moving platform 135, and a secondary three-axis module 134 is provided on one side of the top surface adsorption mechanism 133.

[0054] The rack and pinion motion mechanism 132 is equipped with a main three-axis module 113, the moving ends of the main three-axis module 113 are all connected to the main laser cutting machine 118, and the moving ends of the auxiliary three-axis module 134 are equipped with auxiliary laser cutting machines 117.

[0055] A receiving mechanism 12 is provided on one side of the support platform 131, and a guiding mechanism 22 is provided on the side of the support platform 131 away from the receiving mechanism 12.

[0056] like Figure 2 , Figure 3 As shown, specifically, the support platform 131 has a rack and pinion motion mechanism 132 on its surface. The rack and pinion motion mechanism 132 is parallel to the central axis of the support platform 131. The rack and pinion motion mechanism 132 is used to control the axial movement of the main three-axis module 113. Since the main laser cutting machine 118 is connected to the main three-axis module 113, the movement of the main three-axis module 113 will drive the main laser cutting machine 118 to move. The rack and pinion motion mechanism 132 is used to adjust the spacing between the laser cutting machines to meet the requirement of simultaneously cutting three features of different lengths and shapes. The main three-axis module 113 is driven independently in the X, Y, and Z directions. The mechanism adjusts the position of the main laser cutting machine 118. Several main three-axis modules 113 are provided, and the number of main laser cutting machines 118 is the same as that of the main three-axis modules 113. The main laser cutting machines 118 operate independently, cutting the silicon steel sheet according to their settings. A single auxiliary three-axis module 134 and auxiliary laser cutting machine 117 are provided for the final cutting of the silicon steel sheet. The long strip of silicon steel sheet is transformed into the desired silicon steel sheet. The silicon steel sheet is then processed into trapezoidal sheets. Circular holes are cut into short pieces from the same sheet, and circular holes are cut into long pieces from adjacent pieces.

[0057] There are two cutting methods depending on the length of the material. The first method, for shorter materials, designates the silicon steel sheet cut by the secondary laser cutting head as the first sheet, while the main laser cutting head adjacent to the secondary laser cutting head completes the V-shaped notch cut, designating this section of the silicon steel sheet as the second sheet. Because the circular hole positions and the V-shaped notch processing positions of the short material are too close, simultaneous processing on the same sheet would cause interference and collision between the cutting heads. Therefore, the two laser cutting heads responsible for the circular hole cutting process are correspondingly set on the third sheet. This staggered processing method avoids the risk of cutting head interference, ensuring the safety and stability of the cutting operation. The second method, for longer materials, uses the secondary laser... The silicon steel sheet cut by the cutting head is designated as the first sheet, and the silicon steel sheet with the V-shaped notch cut completed by the main laser cutting head adjacent to the auxiliary laser cutting head is designated as the second sheet. Since the distance between the circular hole and the V-shaped notch processing position of the long sheet is relatively far, it meets the spatial conditions for multiple heads to work simultaneously. Therefore, the other main laser cutting heads are controlled to simultaneously complete the circular hole cutting of the second sheet, and the last main laser cutting head processes the circular hole on the right side of the third sheet. This design can complete the circular hole cutting and V-shaped notch cutting on the same sheet, effectively shortening the structural layout length of the circular hole cutting area, while reducing the frequency error of the stepping feed and improving the relative position accuracy of each cutting feature on the same sheet.

[0058] The feeding mechanism 21 includes an uncoiler 211 and a bending guide plate 212. The bottom end of the bending guide plate 212 is provided with a mounting frame 213. The mounting frame 213 is provided with straight guide plates 214 on both sides. One end of the straight guide plate 214 is rotatably connected to the mounting frame 213. The bottom end of the straight guide plate 214 is provided with a main cylinder 215. The fixed end of the main cylinder 215 is rotatably connected to the mounting frame 213. The output end of the main cylinder 215 is rotatably connected to the bottom end of the straight guide plate 214.

[0059] The uncoiler 211 is located at the end of the mounting frame 213 away from the guide mechanism 22.

[0060] like Figure 5 , Figure 7 As shown, specifically, the uncoiler 211 is existing technology, used to place silicon steel coils and perform stable uncoiling. The sheet material conveyed by the uncoiler 211 is an unprocessed strip sheet. During manual feeding, the main cylinder 215 acts as a power source to control the linear guide plate 214 to drive the transport roller group 216 to a horizontal state, so that the linear guide plate 214 forms a plane for rapid transport of the strip sheet. When manual feeding is completed, the main cylinder 215 acts as a power source to control the linear guide plate 214 to reset, thereby driving the transport roller group 216 to adhere to the curved guide plate 212 in an arc state, guiding the silicon steel sheet material into the buffer area in a U-shape. In the uncoiling state, the strip sheet material is sent out from the uncoiler 211 and enters and exits the buffer area in a U-shaped posture.

[0061] The surface of the curved guide plate 212 is provided with a set of transport rollers 216.

[0062] like Figure 7 As shown, specifically, the transport roller group 216 is composed of multiple rollers. During feeding, the straight guide plates 214 are parallel to each other, and the transport roller group 216 is arranged on the surface of the straight guide plates 214. At this time, the transport roller group 216 is parallel to the horizontal axis. After feeding, the strip silicon steel sheet is buffered and stored. The straight guide plates 214 are retracted, and the transport roller group 216 is arranged on the curved guide plates 212. At this time, the space between adjacent curved guide plates 212 is a buffer area. When the uncoiler 211 continuously feeds and the drive mechanism 222 is in a paused cutting state, the excess silicon steel sheet will be temporarily stored in the buffer area. When the drive mechanism 222 resumes feeding, the buffer area gradually releases the stored silicon steel sheet to avoid material accumulation due to fast uncoiling and slow feeding, or material being stretched and deformed due to slow uncoiling and fast feeding, thus ensuring that the silicon steel sheet conveying process is always stable.

[0063] The guiding mechanism 22 includes a double-sided centering module 221, and a driving mechanism 222 is provided between one side of the double-sided centering module 221;

[0064] Both the bilateral centering module 221 and the drive mechanism 222 are located on the surface of the support platform 131;

[0065] The drive mechanism 222 works in conjunction with the main laser cutting machine 118.

[0066] like Figure 4 As shown, specifically, after passing through the conveyor roller group 216, the silicon steel plate passes through the double-sided centering module 221 and moves to the drive mechanism 222. The drive module mechanism 222 limits the height of the strip silicon steel plate, and the guide mechanism 22 is used to limit the silicon steel plate. The inner bottom of the double-sided centering module 221 is provided with a limiting stop 223, which contacts the long sides of the silicon steel plate on both sides to continuously contact the silicon steel plate without restricting the continuous movement of the silicon steel plate. The drive mechanism 222 serves as a power source to drive the silicon steel plate to move, and the feed efficiency is adjusted according to the cutting time of the main laser cutting machine 118.

[0067] Several double-sided centering modules 221 are provided, and a limiting stop 223 is provided on the side facing adjacent double-sided centering modules 221.

[0068] like Figure 4As shown, specifically, the inner side of the limiting stop 223 is slightly in contact with the edge of the silicon steel plate, which can limit the lateral displacement of the silicon steel plate in real time, prevent the silicon steel plate from deviating to both sides, ensure that the material is always conveyed in a straight line to the drive mechanism 222 and the core cutting mechanism 11, suppress the tendency of the thin material edge to curl up, avoid material jamming or conveying slippage when entering the drive roller or driven roller, and ensure the continuity of the entire conveying link. The silicon steel plate is fed into the cutting station through the limiting stop 223. The cross-cutting machine automatically allocates the cutting process according to the length of the material. The three main laser cutting machines 118 are automatically arranged to the position to be cut, and the auxiliary laser cutting machine 117 automatically moves to the cutting station according to the cutting position. The three main laser cutting machines 118 and the auxiliary laser cutting machine 117 perform cutting operations simultaneously. Through the step feeding method, the drive mechanism 222 feeds once per step, and one piece of material is sent to the receiving mechanism 12.

[0069] The receiving mechanism 12 includes a connecting seat 121 and a movable flap 122. The movable flap 122 is located inside the connecting seat 121 and is rotatably connected to the inner wall of the connecting seat 121. A secondary cylinder 123 is provided on one side of the connecting seat 121, and multiple conveyor belts 124 are provided on one side of the connecting seat 121. The multiple conveyor belts 124 are arranged at an incline. The fixed end of the secondary cylinder 123 is connected to the outer wall of the connecting seat 121, and the output end of the secondary cylinder 123 is connected to the movable flap 122.

[0070] The connecting seat 121 is located on the side of the support platform 131 away from the secondary triaxial module 134.

[0071] like Figure 8 , Figure 9 As shown, specifically, the connecting seat 121 serves as the main supporting component of the receiving mechanism 12, forming a material conveying channel inside to receive the finished silicon steel sheet material from the cutting mechanism. The movable flap 122 is hinged to the inner wall of the connecting seat 121 via a rotating shaft, forming a rotatable guide structure. Its rotatable action is driven and controlled by the auxiliary cylinder 123. When the piston rod of the auxiliary cylinder 123 extends or retracts, it will drive the movable flap 122 to rotate around the hinge point, thereby adjusting the conveying guide path of the material in the connecting seat 121, ensuring that the finished sheet material accurately enters the subsequent conveyor belt 124 structure. The connecting seat 121 is far away from the cutting mechanism. Multiple conveyor belts 124 arranged on one side of the cutting mechanism 11 are inclined, and the inclination angles of the multiple conveyor belts 124 are also different, resulting in different transport positions. In the cutting process, the trapezoidal silicon steel sheets are arranged alternately at equal intervals for alternating cutting. When passing the connecting seat 121, the movable flap 122 rotates continuously. When the movable flap 122 flips upward, the silicon steel sheets move to the higher conveyor belt 124. When the movable flap 122 flips downward, the silicon steel sheets move to the lower conveyor belt 124, so as to realize the separate collection of the two different arrangements of silicon steel sheets.

[0072] Each conveyor belt 124 has a receiving frame 125 on the side away from the connecting seat 121, a lifting module 126 is provided inside the receiving frame 125, and a receiving trolley 127 is provided between the lifting modules 126.

[0073] like Figure 10 As shown, specifically, the receiving frame 125, as the bearing component at the end of the receiving mechanism 12, is precisely connected to the discharge end of the inclined conveyor belt 124. The inside of its frame forms a channel adapted to the operation of the receiving trolley 127, ensuring that the trolley remains stable during the lifting process.

[0074] Working principle: After the entire roll of silicon steel sheet is manually placed on the uncoiler 211, the uncoiler 211 releases the strip sheet. In the initial state, the main cylinder 215 drives the linear guide plate 214 to drive the transport roller group 216 to a horizontal state. The transport roller group 216 driven by the linear guide plate 214 on the opposite side docks to form a flat conveying plane. After the sheet passes through the double-sided centering module 221 and arrives at the drive mechanism 222, the linear guide plate 214 resets to form a buffer area to balance the difference between the uncoiling and cutting speeds and avoid material accumulation or stretching deformation. Subsequently, the double-sided centering module 221 of the guide mechanism 22 corrects the lateral position of the sheet through the limiting edge 223. The top surface adsorption mechanism 133 firmly fixes the sheet to the support platform 131. The drive mechanism 222 drives the sheet to feed towards the cutting mechanism 11. The cutting stage adopts a step-by-step feeding and multi-head division of labor cutting mode. The rack and pinion conveyors on both sides of the support platform 131... The drive mechanism 132 adjusts the spacing of the main three-axis module 113 to simultaneously cut three features of different lengths and shapes. The main and auxiliary laser cutting heads achieve precise positioning with the help of three-axis drive, and the nozzle 114 continuously delivers high-pressure nitrogen to isolate oxygen and eliminate cutting burrs. In the short material cutting mode, the circular hole cutting and V-shaped notch cutting are distributed to different plates to avoid interference through staggered processing. In the long material cutting mode, multiple feature cuttings are completed simultaneously on the same plate to improve efficiency. After the finished product is transported to the receiving mechanism 12 connecting seat 121, the auxiliary cylinder 123 drives the movable flip plate 122 to flip and adjust the guide path, so that the plate slides into the corresponding inclined conveyor belt 124. The lifting module 126 in the receiving frame 125 drives the receiving trolley 127 to slowly descend according to the stacking height of the plates to achieve stable stacking. After the trolley is fully loaded, the operator can replace it with an empty trolley to resume continuous production.
