Description

Technical Field

[0001] The invention relates to the field of laser cutting, and in particular to a full-automatic laser cutting machine. Background Art

[0002] Background technology of laser cutting machine for interior panels of new energy vehicles mainly relies on the rapid development and wide application of laser processing technology. Laser processing technology uses the characteristics of the interaction between laser beam and matter to cut, weld, surface treat, punch and micro-process materials (including metals and non-metals). In the new energy vehicle manufacturing industry, laser cutting technology has become an indispensable processing method, especially in the manufacturing process of automotive interior panels. As an important part of the interior of the car, the quality and precision of the interior panels of new energy vehicles are directly related to the comfort and safety of passengers. Traditional cutting methods often have problems such as low cutting accuracy, low efficiency and material waste, and the emergence of laser cutting technology effectively solves these problems. The laser cutting machine irradiates the cut material with a laser beam, so that the material is quickly heated to the vaporization temperature and evaporates to form holes. As the beam moves on the material, the holes continuously form a very narrow slit, thereby completing the cutting of the material. This cutting method is not only high in precision and speed, but also can realize automatic operation, greatly improving production efficiency and product quality. When the existing laser cutting machine performs the cutting task, the heated part of the cutting object will produce vaporization. If the harmful gases generated in this process are not collected in time, they will spread to the surrounding environment, which may have a negative impact on the environmental quality and the health of the operators.

A plurality of filter holes 38 are opened on the outer peripheral wall of the brush cylinder 12, and the electromagnetic valve 47 is opened, and the set There is a complete air flow passage between the air inlet pipe 23 and the air outlet pipe 24, and then the external air pump connected to the air outlet pipe 24 is operated, and the air flow enters the upper part of the inner cavity of the brush tube 12 through the air inlet pipe 23, and then the air flow flows out through the filter hole 38 at the upper part of the brush tube 12 and flows downward; the air flow flowing out from the filter hole 38 at the upper part of the brush tube 12 can blow the bristles 13 to swing, so as to enhance the cleaning effect of the bristles 13 on the sandpaper 9; in addition, the flowing air flow can also cool the sandpaper 9 during the grinding process, so as to extend the service life of the sandpaper 9; in addition, a small amount of harmful gas that has not escaped will adhere to the cutting part of the decorative plate 48, and the flowing air flow can also recycle this part of the harmful gas for a second time;In addition, when the sandpaper 9 is grinding, the motor 3 20 drives the driving gear 21 to perform reciprocating forward and reverse motions, and the driving gear 21 drives the toothed shell 18 to perform reciprocating forward and reverse motions.

When the spring 1 34 is a strong spring and the elastic force of the spring 1 34 is greater than the sum of the elastic forces of the plurality of springs 3 29, the airflow entering the brush cylinder 12 will first push the brush cylinder 12 upward or downward, and only after the air pressure inside overcomes the elastic force of the spring 1 34, will the airflow flow through the air hole 31 toward the filter hole 38. In this process, the upward or downward moving brush cylinder 12 will drive the bristles 13 on its outer peripheral wall to reciprocate up and down, thereby further enhancing the cleaning effect of the bristles 13 on the sandpaper 9. ;

[0036] Working principle: When in use, the electric push rod 44 drives the laser cutting machine body 46 to move downward, so that the laser cutting machine body 46 moves to the specified position, and then the laser cutting machine body 46 cuts the decorative plate 48; during the cutting process, the plastic parts at the connection between the decorative plate 48 body and the water inlet are heated and gasified. At this time, the solenoid valve 47 set on the air inlet pipe 23 is closed, and the external air pump connected to the air outlet pipe 24 is operated. The harmful gas generated during cutting is sucked into the inner cavity of the shell 3 under the action of the air pump, and then the harmful gas passes through the brush tube 12. The filter holes 38 on the peripheral wall enter the inner cavity of the brush cylinder 12. As the gas in the inner cavity of the pipeline 16 located at the lower side is pumped away by the external air pump, the pressure plate 1 35 located at the lower side moves downward under the action of the air pressure difference, and the corresponding air hole 31 is opened. The harmful gas passes through the air hole 31, the mounting seat 10, the gas transmission shell 27, the ventilation hole 28, the ventilation hole 1 26 and the pipeline 16 in sequence, and then the harmful gas passes through the ring body 17, the ventilation hole 3 22 and the toothed shell 18 into the inside of the outlet pipe 24, and finally the harmful gas enters the gas collection and purification device through the outlet pipe 24;

[0037] When the cutting is completed, the electric push rod 2 39 drives the shell 3 to move in the direction of the decorative plate 48, so that the cut part of the decorative plate 48 extends into the inner cavity of the shell 3, and then the electric push rod 3 41 drives the sealing plate 42 to move in the direction of the decorative plate 48, and the upper and lower sets of sealing plates 42 are used to wrap the end of the decorative plate 48, so that the inner cavity of the shell 3 forms a relatively closed space; wherein, the sealing strip 43 further enhances the airtightness of the joint between the sealing plate 42 and the decorative plate 48; then the motor 2 15 and the motor 1 4 are operated simultaneously, and the motor 2 15 drives the roller 8 and the sandpaper 9 to rotate, and the burrs generated at the cutting part of the decorative plate 48 are removed by means of the rotating sandpaper 9. Grinding is performed to enhance the flatness of the cut portion of the decorative plate 48; at the same time, the motor 4 is driven by the screw rod 5 to rotate, the rotating screw rod 5 drives the linkage ring 7 to move back and forth, and the linkage ring 7 drives the roller 8 and the sandpaper 9 to move back and forth, so as to perform a reciprocating grinding operation on the cut portion of the decorative plate 48; at the same time, the rotating roller 8 drives the mounting seat 10 to rotate through the transmission belt 11, the mounting seat 10 drives the brush cylinder 12 to rotate, and the brush cylinder 12 drives a plurality of bristles 13 to rotate, and the plastic particles adhered to the surface of the sandpaper 9 are cleaned by means of the rotating bristles 13 to prevent the adhered plastic particles from affecting the normal grinding operation of the sandpaper 9;

Then, the external air pump connected to the air outlet pipe 24 is operated, and the air flow enters the upper part of the inner cavity of the brush barrel 12 through the air inlet pipe 23, and then the air flow flows out through the filter hole 38 at the upper part of the brush barrel 12 and flows downward; the air flow flowing out from the filter hole 38 at the upper part of the brush barrel 12 can blow the bristles 13 to swing, so as to enhance the cleaning effect of the bristles 13 on the sandpaper 9; in addition, the flowing air flow can also cool the sandpaper 9 during the grinding process, so as to extend the service life of the sandpaper 9. ; In addition, a small amount of undispersed harmful gas will adhere to the cut part of the decorative plate 48, and the flowing airflow can also recycle this part of the harmful gas; in addition, when the sandpaper 9 is grinding, the motor three 20 drives the driving gear 21 to perform reciprocating forward and reverse motions, and the driving gear 21 drives the toothed shell 18 to perform reciprocating forward and reverse motions. The toothed shell 18 can drive the two ventilation holes three 22 to perform reciprocating forward and reverse motions, so as to alternately switch the air intake and air outlet of the two pipes 16, and then perform gas recoil on the plastic particles stuck in the filter hole 38 during the grinding process. , thereby reducing the probability of plastic particles getting stuck in the filter hole 38; it should be noted that the middle part of the air inlet pipe 23 is a retractable hose. When the air inlet pipe 23 follows the toothed shell 18 to perform reciprocating forward and reverse movements, the air inlet pipe 23 can adaptively perform a retractable operation. In addition, the air outlet pipe 24 is rotatably connected to the input end of the external air pump, and the rotating toothed shell 18 does not affect the normal operation of the external air pump. In addition, a plurality of ventilation holes 28 are opened on the top of the air delivery shell 27. When the air delivery shell 27 follows the mounting seat 10 to perform a left and right reciprocating movement, the plurality of ventilation holes 28 will alternately move with the opposite side. The corresponding pipe 16 is aligned, which ensures the smooth flow of air inside the pipe 16; at the same time, since the spring 134 is a strong spring and the elastic force of the spring 134 is greater than the sum of the elastic forces of several springs 329, the airflow entering the brush barrel 12 will first push the brush barrel 12 to move up or down, and after the air pressure inside it overcomes the elastic force of the spring 134, the airflow will flow through the air hole 31 to the filter hole 38. In this process, the brush barrel 12 that moves up or down will drive the bristles 13 on its outer wall to move up and down, so as to further enhance the cleaning effect of the bristles 13 on the sandpaper 9.
