[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Debris adsorption treatment to avoid personal injury. Debris enters from the adsorption port at the bottom of the adsorption hood. The debris is blocked by the screen inside the adsorption hood, separating the debris and air. The debris is deposited on the screen. The air passes through the screen and enters the filter chamber. Then it enters the air inlet of the drive shaft through the filter chamber.

[0024] 2. Adaptable to plates of varying specifications, with strong versatility. When a plate is conveyed between the two conveyor wheels by the feed line, the plate presses the upper conveyor wheel upward, compressing the first spring. Simultaneously, the plate presses the lower conveyor wheel downward, compressing the first spring. This allows the two conveyor wheels to clamp and position the plate while adapting to varying plate thicknesses, better meeting the actual production needs of corner panels. The electric cylinders B on either side respectively drive the reciprocating plates, which in turn drive the conveyor wheels on either side to accommodate different plate shapes, improving the versatility of the corner panel production equipment and meeting diverse usage requirements.

[0025] 3. According to the thickness of the plate, the power of the laser cutting head is flexibly adjusted to ensure normal cutting. The control system simultaneously connects the semicircular rings on the two sets of conveyor wheels and one end of the coil to the circuit, so that the current enters from the upper semicircular ring, flows through the effective number of turns of the coil, and then flows out from the lower semicircular ring to the control system. The control system detects the current and calculates the thickness of the plate. The control system adjusts the power of the laser cutting head and laser generator according to the thickness of the plate to ensure normal cutting of the plate.

[0026] 4. Use high-temperature debris to generate current for cutting, reducing equipment energy consumption. The two semiconductors and metal plate on thermocouple A are the hot end of the Seebeck effect, while thermocouple B is the cold end of the Seebeck effect. The high-temperature debris approaches thermocouple A, causing the temperature of thermocouple A to rise, making the hot end temperature higher than the cold end. The hot and cold ends generate current through the Seebeck effect and transmit it to the control system. The control system detects this current and calculates the temperature of the debris. The control system then processes this current through rectification and voltage conversion before using it for laser cutting, achieving energy recovery and reducing energy consumption of corner panel production equipment.

The rotating motor 43 has a built-in pressure sensor and an encoder. The pressure sensor and the negative pressure system in the rotating motor 43 can monitor the weight of the debris on the screen 44. When the debris on the screen 44 increases, the value of the pressure sensor in the rotating motor 43 increases and is fed back to the control system. The control system uses the electromagnet 44 2 cooperates with the negative pressure system to realize the cleaning of the screen 44; the encoder in the rotating motor 43 is used to monitor the rotation angle of the transmission shaft 42 and the screen 44 and feeds back to the control system. When the air resistance extracted by the negative pressure system becomes larger, the control system knows that a large amount of dust has adhered to the screen 44 facing the adsorption port.

The electromagnets 442 are arranged along the inner wall of the adsorption cover 4 and are electrically connected to the control system.

[0044] The cutting assembly includes a laser cutting head 31 and a laser generator (not shown in the figure). The laser cutting head 31 and the laser generator are electrically connected. The laser cutting head 31 and the laser generator cooperate to realize laser cutting of the plate 13. A limiting groove is provided on the bracket 111.

The electric cylinder C33 drives the laser cutting head 31 and the laser generator to move longitudinally through the fixed plate, so that the laser cutting head 31 is close to the plate 13 to facilitate the laser cutting process of the plate 13.

[0045] A temperature difference plate A41 is provided on the inner wall of the adsorption hood 4. There are multiple groups of temperature difference plates A41. The multiple groups of temperature difference plates A41 are arranged along the inner wall of the adsorption hood 4. The temperature difference plates A41 are located on one side of the electromagnet 442. The adsorption hood 4 is made of heat-insulating material. A temperature difference plate B411 is provided on the outside of the adsorption hood 4. There are multiple groups of temperature difference plates B411. The multiple groups of temperature difference plates A41 and the multiple groups of temperature difference plates B411 correspond one to one. The temperature difference plates B411 are in contact with the external air and are at normal temperature. Two semiconductors of different materials and a metal plate are provided on the temperature difference plates A41 and the temperature difference plates B411. One end of the two semiconductors of different materials are connected to the metal plate. The two semiconductors on the temperature difference plate A41 and the two semiconductors on the temperature difference plate B411 are connected by wires, and one of the wires is connected to the control system. After laser cutting, the plate 13 will produce high-temperature debris. The negative pressure system will suck the high-temperature debris into the adsorption hood 4 through the adsorption port. After entering the adsorption hood 4, the high-temperature debris is deposited on the screen 44. At this time, the two semiconductors and the metal plate on the thermocouple plate A41 are the hot ends of the Seebeck effect, and the thermocouple plate B411 is the cold end of the Seebeck effect. The high-temperature debris approaches the thermocouple plate A41, causing the temperature of the thermocouple plate A41 to rise, so the hot end temperature is higher than the cold end temperature. The hot end and the cold end generate current through the Seebeck effect and transmit it to the control system. The control system detects this part of the current and obtains the temperature of the debris through calculation. After that, the control system uses this part of the current for laser cutting after rectification and transformation, thereby realizing energy recovery and reducing the energy consumption of the corner plate production equipment.

[0046] Working principle: Press the start button on the control panel 1, the equipment starts, the staff places the plate 13 on the feed line, and the control system drives the plate 13 to move to the right through the roller 14 on the feed line. The plate 13 is transported to the position between the two conveying wheels 21 through the feed line. The plate 13 pushes the upper conveying wheel 21 to move upward on the sliding shaft. At the same time, the plate 13 pushes the lower conveying wheel 21 to move downward on the sliding shaft. The upper and lower conveying wheels 21 compress the first spring at the same time. The upper and lower conveying wheels 21 can adapt to different thicknesses of the plates 13 while positioning and clamping the plate 13.

[0047] When the plate 13 is conveyed between the two conveying wheels 21 through the feeding line, the roller 14 in the feeding line feeds back the displacement data of the plate 13 to the control system. The control system controls the driving motor 2 on the reciprocating plates 12 on both sides of the frame 11 to drive the sliding shaft to rotate, and the sliding shaft drives the two sets of conveying wheels 21 to rotate at the same time. The conveying wheels 21 on both sides of the frame 11 cooperate to drive the plate 13 to continue to move to the right. The control system simultaneously connects the semicircular rings 212 and one end of the coil 22 on the two sets of conveying wheels 21 to the circuit, so that the current enters from the upper semicircular ring 212, flows through the effective number of turns of the coil 22, and then flows out from the lower semicircular ring 212 to the control system. The control system detects the current and obtains the thickness of the plate 13 through calculation. At this time, the effective number of turns of the coil 22 refers to the number of turns between the semicircular rings 212 on both sides.

[0048] After the control system obtains the thickness of the plate 13, the control system adjusts the power of the laser cutting head 31 and the laser generator according to the thickness of the plate 13 to ensure normal cutting of the plate 13; then the control system first cuts off the power to the coil 22 and the semicircular rings 212 on both sides, and then connects the upper semicircular ring 212 and the coil 22 to the circuit. The current enters from the upper semicircular ring 212, flows through the effective number of turns of the coil 22, and flows out from one end of the coil 22. The control system detects the current and obtains the height of the upper side of the plate 13 through calculation. The effective number of turns at this time is the number of turns between the upper semicircular ring 212 and one end of the coil 22.

[0049] When the control system obtains the height data of the upper side of the plate 13, the control system first cuts off the power to the upper semicircular ring 212 and the coil 22, and then connects the lower semicircular ring 212 and one end of the coil 22 to the circuit. The current enters from the lower semicircular ring 212, flows through the effective turns of the coil 22, and then flows out from one end of the coil 22 to the control system. The control system detects the current and obtains the height of the lower side of the plate 13 through calculation. The effective number of turns at this time refers to the number of turns between the lower semicircular ring 212 and one end of the coil 22.

[0050] Since a plurality of conveying wheels 21 are provided on the reciprocating plates 12 on both sides of the frame 11, the control system can obtain the upper height and the lower height of the plate 13 at different positions, and the control system compares the obtained upper height data and the lower height data of the plate 13 with the set tolerances respectively. When the control system obtains that the upper height data or the lower height data is not within the set tolerance range, that is, the plate 13 is bent or deformed or the specifications conflict, the control system determines that the plate 13 is unqualified or the specifications of the plate 13 conflict with the production requirements. At this time, the buzzer in the control panel 1 alarms to remind the staff, and the control system controls the drive motor 2 to reverse, and the drive motor 2 drives the plate 13 to move to the left and return to the feed line through the conveying wheel 21, and is discharged to the left under the reverse conveyance of the roller 14 of the feed line, which can avoid the defective products of the front-end process (such as deformation or bending of the plate 13) from entering the laser cutting production process, and eliminate defective products caused by incorrect specifications.

[0051] When the upper and lower height data of the plate 13 obtained by the control system are within the set tolerance range, the control system determines that the plate 13 is a qualified product and can be laser cut. The drive motor 2 continues to drive the plate 13 to move to the right through the conveyor wheel 21. The conveyor wheels 21 on both sides cooperate to convey the position where the plate 13 needs to be cut to directly below the laser cutting head 31. At this time, the encoder in the drive motor 2 feeds back the displacement data of the plate 13 to the control system. The control system controls the electric cylinder C33 to drive the laser cutting head 31 to move downward close to the plate 13. After that, the electric cylinder A3 pushes the sliding plate 32 to move, and the sliding plate 32 drives the electric cylinder C33 to move. The electric cylinder C33 drives the laser cutting head 31 and the laser generator to move through the fixed plate. While moving, the laser cutting head 31 cooperates with the laser generator to laser cut the plate 13. Driven by the electric cylinder A3, the laser cutting head 31 moves from one end of the plate 13 to the other end to cut the plate 13.

[0052] After being cut, the plate 13 is divided into a plurality of small pieces. The conveying wheels 21 on both sides convey the plurality of small pieces to the right to the roller 14 of the blanking line, and the small pieces are moved to the right by the roller 14 of the blanking line and discharged.

[0053] While the laser cutting head 31 is laser cutting the plate 13, debris will be generated at the position where the plate 13 is laser cut. At this time, the control system controls the operation of the negative pressure system and the opening of the solenoid valve in the adsorption port. The debris enters from the adsorption port at the bottom of the adsorption hood 4. The debris is blocked by the screen 44 in the adsorption hood 4, so that the debris and the air are separated and deposited on the screen 44. The air passes through the screen 44 into the filter chamber and enters the air inlet of the drive shaft 42 through the filter chamber. After entering the interior of the drive shaft 42 from the air inlet, it enters the negative pressure system through the pipeline and the air slip ring. The negative pressure system discharges this part of the air into the atmosphere after treatment.

[0054] After a long period of operation, a large amount of debris will adhere to the surface of the screen 44. At this time, the air resistance extracted by the negative pressure system through the adsorption port, the filter chamber and the transmission shaft 42 increases, and the negative pressure system feeds back the pressure data to the control system. The control system controls the rotating motor 43 to drive the transmission shaft 42 to rotate a certain angle, and the transmission shaft 42 drives the cross plate 421 and the screen 44 to follow and rotate a certain angle, so that the new screen 44 is facing the adsorption port, realizing the position adjustment of the screen 44, ensuring the separation of air and debris, and ensuring normal laser cutting of the plate 13.

[0055] When all the screens 44 are covered with debris, the resistance of the rotating motor 43 to the rotation of the transmission shaft 42 increases, and the pressure sensor in the rotating motor 43 feeds data back to the control system. The control system determines that the screen 44 needs to be cleaned. At this time, the buzzer in the control panel 1 alarms to remind the staff, and the staff places the collection box directly under the adsorption port. At this time, the negative pressure system works in reverse. The negative pressure system pressurizes the external air and transports it to the transmission shaft 42 through the pipe and the air slip ring. The pressurized air is transported to the filter chamber through the inside of the transmission shaft 42 and the air inlet. The pressurized air passes through the screen 44 and is sprayed on the debris. The pressurized air pushes the debris out of the adsorption port and falls into the collection box. The debris in the collection box is further processed by the staff.

[0056] While the screen 44 is being cleaned, the control system continuously energizes and deenergizes the electromagnet 442. When the electromagnet 442 is energized, the electromagnet 442 attracts the magnet 441 on the screen 44. Under the action of attraction, the magnet 441 drives the folds on the screen 44 to gradually unfold, causing the screen 44 between the two sets of horizontal plates 421 to protrude toward the side of the electromagnet 442. When the electromagnet 442 is deenergized, the screen 44 bulges toward the side away from the electromagnet 442 under its own elastic force and restores the folded state. By continuously energizing and deenergizing the electromagnet 442, the screen 44 is continuously vibrated, and the screen 44 synchronously drives the debris to vibrate, making it easier for the debris to fall from the screen 44 and be discharged from the adsorption port.
