[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. Chip adsorption treatment to avoid personal injury. The chips enter from the adsorption port at the bottom of the adsorption hood. The chips are blocked by the screen in the adsorption hood, separating the chips from the air. The chips are deposited on the screen, and the air passes through the screen into the filter chamber and then enters the intake hole of the transmission shaft through the filter chamber.

[0024] 2. It can adapt to plates of different specifications and has strong versatility. When the plate is conveyed by the feeding line between the two conveying wheels, the plate squeezes the upper conveying wheel to move upward and compress the first spring. At the same time, the plate squeezes the lower conveying wheel to move downward and compress the first spring. While the two conveying wheels clamp and position the plate, it can adapt to different plate thicknesses, better meeting the actual production requirements of the corner plate. The electric cylinders B on both sides drive the reciprocating plates on both sides respectively, and drive the conveying wheels on both sides respectively through the electric cylinders B on both sides to adapt to plates of different shapes, improving the versatility of the corner plate production equipment and meeting different usage requirements.

[0025] 3. According to the thickness of the plate, flexibly adjust the power of the laser cutting head to ensure normal cutting work. The control system simultaneously connects one end of the semi-circular rings and coils on the two conveying wheels to the circuit, enabling the current to enter from the upper semi-circular ring, flow through the effective number of turns of the coil, and then flow out from the lower semi-circular ring to the control system. The control system detects this current and calculates the thickness of the plate through calculation. The control system adjusts the power of the laser cutting head and the laser generator according to the thickness of the plate to ensure normal cutting of the plate.

[0026] 4. Utilize the high-temperature chips to generate current for cutting treatment, reducing the energy consumption of the equipment. The two semiconductors and the metal plate on the thermoelectric plate A are the hot ends of the Seebeck effect, and the thermoelectric plate B is the cold end of the Seebeck effect. The high-temperature chips approach the thermoelectric plate A, increasing the temperature of the thermoelectric plate A. Therefore, the temperature of the hot end is higher than that of the cold end. 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 calculates the temperature of the chips through calculation. Then, the control system processes this part of the current through rectification, voltage transformation, etc. and uses it for laser cutting, realizing the recycling of energy and reducing the energy consumption of the corner plate production equipment.

Both of the two conveying wheels 21 are slidably installed on the sliding shaft through splines. The two conveying wheels 21 are arranged in a mirror image; the diameter of one end of the two conveying wheels 21 close to each other is smaller than that of the other end. A semi-circular ring 212 is arranged at one end of the two conveying wheels 21 far from each other. The semi-circular ring 212 is made of a metal material. The semi-circular ring 212 is in sliding contact with the coil 22. The coil 22 is installed on the reciprocating plate 12. The semi-circular ring 212 and the coil 22 are electrically connected to the control system.

[0041] The upper end of the sliding shaft passes through the support frame 211 and is connected to the output shaft of the driving motor 2, and the driving motor 2 is installed on the reciprocating plate 12; first springs are respectively connected to the middle parts of the two conveying wheels 21 and the sliding shaft, and the first springs are sleeved on the sliding shaft. When the plate 13 is conveyed by the feeding line between the two conveying wheels 21, the plate 13 squeezes the upper conveying wheel 21 to move upward and compress the first spring. At the same time, the plate 13 squeezes the lower conveying wheel 21 to move downward and compress the first spring, so that while the two conveying wheels 21 clamp and position the plate 13, they can adapt to different thicknesses of the plate 13, which better meets the actual production requirements of the corner plate; guide shafts penetrate through the reciprocating plates 12 on both sides of the frame 11, and the reciprocating plates 12 slide on the guide shafts.

[0042] The bracket 111 is installed on the frame 11, and the adsorption hood 4 is installed on the lower side of the bracket 111. There are multiple groups of adsorption hoods 4. The interior of the adsorption hood 4 is hollow, and the longitudinal section of the adsorption hood 4 is cylindrical. An adsorption port is opened at the bottom of the adsorption hood 4. A transmission shaft 42 is rotatably installed inside the adsorption hood 4 through a bearing. An electromagnetic valve is installed in the adsorption port, and the electromagnetic valve is electrically connected to the control system. One end of the transmission shaft 42 passes through the adsorption hood 4 and is connected to the output shaft of a rotary motor 43. The rotary motor 43 is installed on the adsorption hood 4. The rotary motor 43 is internally provided with a pressure sensor and an encoder. The pressure sensor and the negative pressure system in the rotary motor 43 can both 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 rotary motor 43 becomes larger and is fed back to the control system. The control system cooperates with the electromagnet 442 and the negative pressure system to realize the cleaning process of the screen 44. The encoder in the rotary motor 43 is used to monitor the rotation angles of the transmission shaft 42 and the screen 44 and feed them 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. At this time, the rotary motor 43 drives a new screen 44 to face the adsorption port according to the data of the internal encoder and the pressure sensor to ensure the adsorption process of the debris during the laser cutting process. A plurality of cross plates 421 are respectively arranged at both ends of the transmission shaft 42 located inside the adsorption hood 4.

A screen 44 is connected between adjacent two cross plates 421 and between the cross plates 421 at both ends of the transmission shaft 42. The screen 44 is respectively installed on a plurality of cross plates 421.

[0043] A filtering chamber is formed among the screen 44, a plurality of cross plates 421 and the transmission shaft 42. The longitudinal section of the filtering chamber is polygonal, and one side of the polygon faces the adsorption port. The interior of the transmission shaft 42 is hollow, and air inlet holes are arranged on the transmission shaft 42. The transmission shaft 42 is communicated with the filtering chamber through the air inlet holes. The transmission shaft 42 located outside the adsorption hood 4 is connected to the air inlet of an air slip ring through a pipeline. The air outlet of the air slip ring is connected to a negative pressure system (not shown in the figure). The air slip ring is arranged on the transmission shaft 42, and the air slip ring (not shown in the figure) ensures the stable transmission of gas during the rotation of the transmission shaft 42. A plurality of folds and magnets 441 are arranged on the screen 44. Electromagnets 442 are sequentially arranged on the inner wall of the adsorption hood 4 opposite to the magnets 441. The electromagnets 442 are arranged along the inner wall of the adsorption hood 4, and the electromagnets 442 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 perform laser cutting on the plate 13. A limiting groove is provided on the bracket 111. A sliding plate 32 is slidably installed in the limiting groove. The sliding plate 32 slides on the bracket 111 through the limiting groove. The sliding plate 32 is connected to the telescopic rod of the electric cylinder A3. The electric cylinder A3 is installed on the bracket 111. An electric cylinder C33 is vertically installed on the sliding plate 32. A fixing plate is installed on the telescopic rod of the electric cylinder C33. Both the laser cutting head 31 and the laser generator are installed on the fixing plate. Both the laser cutting head 31 and the laser generator are located below the bracket 111. The electric cylinder A3 drives the electric cylinder C33, the fixing plate, the laser cutting head 31 and the laser generator to move horizontally through the sliding plate 32, so that the laser cutting head 31 moves from one end of the plate 13 to the other end and performs cutting. The electric cylinder C33 drives the laser cutting head 31 and the laser generator to move vertically through the fixing plate, so that the laser cutting head 31 approaches the plate 13, facilitating the laser cutting process of the plate 13.

[0045] A thermopile A41 is provided on the inner wall of the adsorption hood 4. There are multiple groups of thermopile A41, and the multiple groups of thermopile A41 are arranged along the inner wall of the adsorption hood 4. The thermopile A41 is located on one side of the electromagnet 442. The adsorption hood 4 is made of heat-insulating material. A thermopile B411 is provided on the outside of the adsorption hood 4. There are multiple groups of thermopile B411, and the multiple groups of thermopile A41 and the multiple groups of thermopile B411 correspond one by one. The thermopile B411 is in contact with the external air and is at room temperature. Two different materials of semiconductors and metal plates are provided on the thermopile A41 and the thermopile B411. One end of the two different materials of semiconductors is connected to the metal plate. The two semiconductors on the thermopile A41 and the two semiconductors on the thermopile B411 are connected by wires, and one of the wires is connected to the control system. After the plate 13 is laser-cut, high-temperature debris will be generated. The negative pressure system sucks the high-temperature debris into the adsorption hood 4 through the adsorption port. After the high-temperature debris enters the adsorption hood 4, it deposits on the screen 44. At this time, the two semiconductors and the metal plate on the thermopile A41 are the hot ends of the Seebeck effect, and the thermopile B411 is the cold end of the Seebeck effect. The high-temperature debris approaches the thermopile A41, causing the temperature of the thermopile A41 to rise. Therefore, the temperature of the hot end is higher than that of the cold end. 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, calculates the temperature of the debris, and then the control system processes this part of the current through rectification and transformation and other processes for laser cutting, realizing the recycling of energy and reducing the energy consumption of the corner plate production equipment.

[0046] Working principle: Press the start button on the control panel 1, and the device starts. The operator places the sheet 13 on the feeding line. The control system drives the sheet 13 to move rightward through the rollers 14 on the feeding line. The sheet 13 is conveyed by the feeding line to the position between the two conveying wheels 21. The sheet 13 pushes the upper conveying wheel 21 to move upward on the sliding shaft, and at the same time, the sheet 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 simultaneously. While positioning and clamping the sheet 13, the upper and lower conveying wheels 21 can adapt to different thicknesses of the sheet 13.

[0047] When the sheet 13 is conveyed by the feeding line to the position between the two conveying wheels 21, the rollers 14 in the feeding line feedback the displacement data of the sheet 13 to the control system. The control system controls the drive motors 2 on the reciprocating plates 12 on both sides of the frame 11 to drive the sliding shaft to rotate. The sliding shaft drives the two groups of conveying wheels 21 to rotate simultaneously. The conveying wheels 21 on both sides of the frame 11 cooperate to drive the sheet 13 to continue moving rightward. The control system simultaneously connects one end of the semi-circular rings 212 and the coil 22 on the two groups of conveying wheels 21 to the circuit, so that the current enters from the upper semi-circular ring 212, flows through the effective number of turns of the coil 22, and then flows out from the lower semi-circular ring 212 to the control system. The control system detects this current and calculates the thickness of the sheet 13 through calculation. At this time, the effective number of turns of the coil 22 refers to the number of turns between the two semi-circular rings 212 on both sides.

[0048] After the control system obtains the thickness of the sheet 13, the control system adjusts the power of the laser cutting head 31 and the laser generator according to the thickness of the sheet 13 to ensure the normal cutting of the sheet 13. Then the control system first cuts off the power supply of the coil 22 and the two semi-circular rings 212 on both sides, and then connects the upper semi-circular ring 212 and the coil 22 to the circuit. The current enters from the upper semi-circular 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 this current and calculates the height of the upper side of the sheet 13 through calculation. At this time, the effective number of turns is the number of turns between the upper semi-circular ring 212 and one end of the coil 22.

[0049] After the control system obtains the height data of the upper side of the sheet 13, the control system first cuts off the power supply of the upper semi-circular ring 212 and the coil 22, and then connects one end of the lower semi-circular ring 212 and the coil 22 to the circuit. The current enters from the lower semi-circular ring 212, flows through the effective number of turns of the coil 22, and then flows out from one end of the coil 22 to the control system. The control system detects this current and calculates the height of the lower side of the sheet 13 through calculation. At this time, the effective number of turns is the number of turns between the lower semi-circular ring 212 and one end of the coil 22.

[0050] Since there are multiple conveying wheels 21 provided on the reciprocating plates 12 on both sides of the rack 11, the control system can obtain the upper-side height and lower-side height of the sheet 13 at different positions. The control system compares the obtained upper-side height data and lower-side height data of the sheet 13 with the set tolerances respectively. When the control system obtains that the upper-side height data or the lower-side height data is not within the set tolerance range, that is, the sheet 13 is bent or deformed or there is a specification conflict, the control system determines that the sheet 13 is a non-conforming product or the specification of the sheet 13 conflicts with the production requirements. At this time, the buzzer in the control panel 1 alarms to remind the staff. The control system controls the driving motor 2 to reverse. The driving motor 2 drives the sheet 13 to move leftward through the conveying wheels 21 and retreats to the feeding line, and is discharged leftward under the reverse conveying of the rollers 14 on the feeding line, which can prevent defective products (such as deformation or bending of the sheet 13) in the front-end process from entering the laser cutting production process and eliminate defective products caused by specification errors.

[0051] When both the upper-side height data and the lower-side height data of the sheet 13 obtained by the control system are within the set tolerance range, the control system determines that the sheet 13 is a qualified product and can perform laser cutting on the sheet 13. The driving motor 2 continues to drive the sheet 13 to move rightward through the conveying wheels 21. The conveying wheels 21 on both sides cooperate to convey the position of the sheet 13 to be cut directly below the laser cutting head 31. At this time, the encoder in the driving motor 2 feeds back the displacement data of the sheet 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 sheet 13. Then, the electric cylinder A3 pushes the sliding plate 32 to move. 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 fixing plate. While moving, the laser cutting head 31 cooperates with the laser generator to perform laser cutting on the sheet 13. The laser cutting head 31 moves from one end of the sheet 13 to the other end under the drive of the electric cylinder A3 to cut the sheet 13.

[0052] After the sheet 13 is cut, it is separated into multiple small pieces. The conveying wheels 21 on both sides convey the multiple small pieces rightward onto the rollers 14 of the discharging line and move and discharge them rightward through the rollers 14 of the discharging line.

[0053] While the laser cutting head 31 performs laser cutting on the sheet 13, debris will be generated at the laser cutting position of the sheet 13. At this time, the control system controls the negative pressure system to work and opens the solenoid valve in the suction port. The debris enters from the suction port at the bottom of the suction hood 4. The debris is blocked by the screen 44 in the suction hood 4 to separate the debris and air. The debris deposits on the screen 44. The air passes through the screen 44 into the filter chamber and enters the air inlet hole of the transmission shaft 42 through the filter chamber. After entering the interior of the transmission shaft 42 from the air inlet hole, it enters the negative pressure system through the pipeline and the air slip ring. The negative pressure system processes this part of the air and discharges it to the atmosphere.

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

[0055] When all the screens 44 are adhered with debris, the resistance of the rotation motor 43 driving the transmission shaft 42 to rotate increases. The pressure sensor in the rotation motor 43 feeds back the data to the control system, and 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. The staff places the collection box directly below 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 inside of the transmission shaft 42 through the pipeline 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 holes. The pressurized air passes through the screen 44 and sprays on the debris, and the pressurized air pushes the debris out from 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 de-energizes the electromagnet 442. When the electromagnet 442 is energized, the electromagnet 442 attracts the magnet 441 on the screen 44. Under the action of the attraction force, the magnet 441 drives the folds on the screen 44 to gradually unfold, so that the screen 44 between the two cross plates 421 protrudes toward the electromagnet 442. When the electromagnet 442 is de-energized, the screen 44 bulges toward the side away from the electromagnet 442 and returns to the folded state under its own elastic force. By continuously energizing and de-energizing the electromagnet 442, continuous vibration of the screen 44 is realized. The screen 44 synchronously drives the debris to vibrate, making it easier for the debris to fall off the screen 44 and be discharged from the adsorption port.
