Description

Technical Field

[0001] The present invention relates to the technical field of laser cleaning, and in particular to a fiber laser cleaning machine. Background Art

[0002] Laser cleaning has the characteristics of no grinding, non-contact, no heat effect and is suitable for objects of various materials. It is considered to be the most reliable and effective solution. At present, common laser cleaning machines include fiber laser machines, laser cleaning heads, control systems and other structures.

[0003] At present, a lot of smoke and dust will be generated around the handheld laser cleaning head during operation. These smoke and dust are not only easily inhaled by workers and easily cause respiratory diseases, but also hinder the laser cleaning head from projecting the laser onto the workpiece surface, which will undoubtedly hinder the normal laser cleaning and slow down the cleaning efficiency of the laser cleaning head. As a result, the workers have to operate the laser cleaning head for laser cleaning while operating the vacuum cleaner for smoke and dust absorption. This requires the workers to do two things at the same time, resulting in a significant increase in the workers' workload. Summary of the Invention

[0004] The purpose of the present invention is to provide a fiber laser cleaning machine in order to solve the above problems, so as to improve the problem that the existing laser cleaning machine will generate a lot of smoke and dust during operation, and the workers need to perform cleaning and dust removal work at the same time, which has a high labor intensity for the workers.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions: a fiber laser cleaning machine comprises a casing, a fiber laser machine is installed inside the casing, a control system is installed on the top of the casing, a laser cleaning head is installed on the surface of the casing, and an auxiliary device is installed on the surface of the laser cleaning head; the auxiliary device comprises an operating handle sleeved on the surface of the laser cleaning head, the lower end of the operating handle is fixedly connected to a guide mechanism, the surface of the guide mechanism is installed with a dust filter mechanism, the end of the dust filter mechanism is fixedly connected to an air duct, the air outlet end of the air duct is fixedly connected to a suction fan embedded in the operating handle, and the air outlet end of the suction fan is fixedly connected to a heat dissipation mechanism sleeved on the surface of the laser cleaning head. The present invention adopts the latest technology fiber laser machine, which is small in size, light in weight, safe and reliable. Compared with the cleaning machine using traditional YAG solid-state laser, the electrical and communication control of the equipment of the present invention is greatly simplified, the structural layout is simpler, the water cooling is integrated, and it is easy to move. In addition, optical fiber is used to transmit energy, and the flexibility of optical fiber can be used to achieve remote control. The lightweight design of the laser cleaning head greatly reduces the load on the robot and is more conducive to automated work. By setting up auxiliary devices, while the staff normally uses the laser cleaning head to clean the dust on the surface of the workpiece, the suction fan absorbs the smoke and dust excited by the laser beam through the air duct. In this process, the dust filter mechanism filters out solid impurities in the smoke and dust, so that the smoke and dust entering the air duct always remain clean. The suction fan then guides the clean air into the heat dissipation mechanism, so that the air cooperates with the heat dissipation mechanism to reduce the temperature of the laser cleaning head to ensure that the laser cleaning head can operate normally. This does not require the staff to remove dust while cleaning the workpiece, which not only ensures that the laser beam can stably irradiate the workpiece surface, but also reduces the workload of the staff. The exhaust of the suction fan is used to dissipate heat for the laser cleaning head, and there is no need to add a separate heat dissipation structure for the laser cleaning head, which effectively reduces the cost required for laser cleaning.

[0006] The top of the protective cover is fixedly connected to the driving motor, and the output shaft of the driving motor passes through the protective cover and is engaged with the adjacent transmission shaft. By providing the dust filter mechanism, when smoke enters the interior of the installation box, the dust filter cloth can filter solid impurities generated in the passage, and the driving motor can drive the transmission shaft connected thereto to rotate, and the transmission shaft continuously rewinds the dust filter cloth, so that the dust filter cloth at the connection point between the installation box and the air duct is always kept clean to ensure the flow rate of air through the installation box, which effectively reduces the frequency of maintenance of the dust filter mechanism as a whole by the staff, making it easier for the staff to use.

[0007] Preferably, the dust filtering mechanism also includes a belt that is transmission-connected to the inside of the protective cover, the inner side of the belt is transmission-connected to two pulleys that are both rotatably connected to the protective cover, the inner side of the pulley is fixedly connected to a connecting shaft, the lower end of the connecting shaft passes through the protective cover and is engaged with the adjacent transmission shaft, the output shaft of the drive motor is fixedly connected to the adjacent connecting shaft, the coordinated use of the belt, pulley and connecting shaft can enable the drive motor to synchronously drive the two transmission shafts, so that the two transmission shafts can synchronously release and reel in the dust filter cloth to ensure that the dust filter cloth is always in a taut state.

[0008] Preferably, the resistance assembly includes a telescopic bellows fixedly connected to the vertical inner wall of the installation box, the end of the telescopic bellows away from the dust filter cloth is connected to the air guide pipe, the end of the telescopic bellows away from the air guide pipe is fixedly connected to a resistance frame in contact with the dust filter cloth, the end of the resistance frame close to the air guide pipe is connected to the telescopic bellows, and the end of the resistance frame close to the air guide pipe is fixedly connected to springs that are evenly distributed and in contact with the installation box, and the springs are always in a compressed state. By setting up the resistance assembly, the spring can drive the resistance frame to always resist the dust filter cloth, so that the dust filter cloth is always in a taut state, which can ensure that the smoke and dust that need to enter the air guide pipe can only enter the air guide pipe along the resistance frame and the telescopic bellows through the dust filter cloth, thereby effectively reducing the probability of leakage of solid impurities in the smoke and reducing the difficulty for staff to maintain subsequent structures.

[0009] Preferably, the end of the interference frame close to the air duct is fixedly connected to a uniformly distributed guide rod, and the end of the guide rod close to the air duct passes through the spring and extends to the interior of the installation box. The guide rod can simultaneously limit the movement trajectory of the interference frame and the spring to reduce the probability of the interference frame and the spring being stuck.

[0010] 4. The repairing kit for automotive dents, according to claim 1, wherein a bottom of the foot stand comprises a through-hole, and the two foot pieces comprise two bosses, wherein the bosses comprise a through-hole, a screw bolt, and a nut. The bosses comprise a through-hole, a screw bolt, and a nut. The bosses comprise a through-hole, a screw bolt, and a nut. The bosses comprise a through-hole, a screw bolt, and a nut.

[0011] Preferably, the surface of the connecting rod is provided with scales, which are evenly distributed on the surface of the connecting rod, and the spacing between two adjacent scales is the same, which enables the staff to more accurately adjust the overall length between the connecting rod and the sleeve, reducing the difficulty of adjustment for the staff.

[0012] Preferably, a ball is embedded in the interior of the sleeve, the lower surface of the ball passes through the outside of the sleeve, and the center point of the ball is set inside the sleeve. The ball can reduce the friction between the sleeve and the workpiece, which can not only reduce the resistance when the sleeve moves, but also reduce the probability of the workpiece being scratched, thereby achieving the dual beneficial effects of drag reduction and protection.

[0013] Preferably, the heat dissipation mechanism includes two heat-conducting copper tubes fixedly connected to the bottom of the suction fan, the upper opening of the heat-conducting copper tube is connected to the air outlet end of the suction fan, the lower end of the heat-conducting copper tube passes through the outside of the operating handle, the heat-conducting copper tube is spirally wound around the surface of the laser cleaning head, and the two heat-conducting copper tubes are staggered and wound around the surface of the laser cleaning head. By setting up a heat dissipation mechanism, when the filtered air enters the interior of the suction fan along the air guide tube, the air of the suction fan is guided into the air guide hopper, and the air guide hopper guides the air into the heat-conducting copper tube. In the process of passing through the heat-conducting copper tube, the air quickly drives the heat accumulated inside the heat-conducting copper tube, so that the heat-conducting copper tube is quickly cooled to ensure that the heat-conducting copper tube can continuously absorb the heat generated by the operation of the laser cleaning head to ensure the normal operation of the laser cleaning head, and the exhaust air of the suction fan is used to dissipate heat for the laser cleaning head, without the need to add a separate heat dissipation structure for the laser cleaning head, which effectively reduces the cost required for laser cleaning.

[0014] Preferably, the top of the thermally conductive copper tube is fixedly connected to an air guide hopper, the top of the air guide hopper is fixedly connected to the suction fan, the thermally conductive copper tube, the air guide hopper and the suction fan are interconnected, and the air guide hopper and the thermally conductive copper tube are integrally formed, which can reduce the resistance of air entering the thermally conductive copper tube, not only reducing the noise during the process of air passing through the thermally conductive copper tube, but also ensuring the flow rate of air inside the thermally conductive copper tube, so as to improve the heat dissipation effect of the laser cleaning head.

[0015] The beneficial effects of the present invention are:

[0016] 1. By setting up an auxiliary device, while the worker is normally cleaning the dust on the surface of the workpiece through the laser cleaning head, the suction fan absorbs the smoke and dust excited by the laser beam through the air duct. In this process, the dust filter mechanism filters out solid impurities in the smoke and dust, so that the smoke and dust entering the air duct are always kept clean. Then the suction fan guides the clean air into the heat dissipation mechanism, so that the air cooperates with the heat dissipation mechanism to reduce the temperature of the laser cleaning head to ensure that the laser cleaning head can operate normally. This does not require the worker to remove dust while cleaning the workpiece, which not only ensures that the laser beam can stably irradiate the workpiece surface, but also reduces the workload of the worker. In addition, the exhaust air of the suction fan is used to dissipate heat for the laser cleaning head, and there is no need to add a separate heat dissipation structure for the laser cleaning head, which effectively reduces the cost required for laser cleaning.

[0017] 2. By setting up a dust filter mechanism, when smoke enters the interior of the installation box, the dust filter cloth can filter out solid impurities in the process, and the drive motor can drive the transmission shaft connected to it to rotate, and the transmission shaft continuously reels the dust filter cloth, so that the dust filter cloth at the connection between the installation box and the air duct is always kept clean to ensure the flow rate of air passing through the installation box. This effectively reduces the frequency of maintenance of the dust filter mechanism as a whole by the staff, making it easier for the staff to use;

[0018] 3. By setting up a guide mechanism, the staff can adjust the overall length of the sleeve and the connecting rod according to the irradiation focus of the laser cleaning head. This can enable the air guide cover to be close to the surface of the workpiece to absorb smoke and dust, thereby reducing the probability of smoke and dust escaping to the surroundings. At the same time, the staff can attach the guide mechanism to the surface of the workpiece to assist the staff in moving the laser cleaning head, which can reduce the burden on the staff when using the laser cleaning head, allowing the staff to use the laser cleaning head for a long time, thereby achieving a good burden-reducing effect;

[0019] 4. By setting up a heat dissipation mechanism, when the filtered air enters the interior of the suction fan along the air duct, the air from the suction fan is guided into the air guide hopper, and the air guide hopper guides the air into the heat-conducting copper tube. In the process of passing through the heat-conducting copper tube, the air quickly drives the heat accumulated inside the heat-conducting copper tube, causing the heat-conducting copper tube to cool down quickly, so as to ensure that the heat-conducting copper tube can continuously absorb the heat generated by the laser cleaning head during operation, so as to ensure that the laser cleaning head can operate normally, and the exhaust air of the suction fan is used to dissipate heat for the laser cleaning head, without the need to add a separate heat dissipation structure for the laser cleaning head, which effectively reduces the cost required for laser cleaning.

The connecting seat 521 is fixedly connected to the surface of the operating handle 51. The bottom of the connecting seat 521 is fixedly connected to two connecting rods 523.

[0035] like Figure 4 As shown, the heat dissipation mechanism 56 includes two heat-conducting copper tubes 561 fixedly connected to the bottom of the suction fan 55, the upper opening of the heat-conducting copper tube 561 is connected to the air outlet end of the suction fan 55, the lower end of the heat-conducting copper tube 561 passes through the outside of the operating handle 51, and the heat-conducting copper tube 561 is spirally wound around the surface of the laser cleaning head 4, and the two heat-conducting copper tubes 561 are staggered and wound around the surface of the laser cleaning head 4; the top of the heat-conducting copper tube 561 is fixedly connected to the air guide hopper 562, and the top of the air guide hopper 562 is fixedly connected to the suction fan 55, the heat-conducting copper tube 561, the air guide hopper 562 and the suction fan 55 are connected to each other, and the air guide hopper 562 and the heat-conducting copper tube 561 are integrally formed.

[0036] When the present invention is in use, when the staff needs to laser clean the workpiece, the staff first connects the laser cleaning head 4 with the fiber laser machine 2, and then fixes the connecting seat 521 to the surface of the operating handle 51 by bolts, and then unplugs the two pins 522, and moves the air guide cover 526 according to the irradiation focus of the laser cleaning head 4. The air guide cover 526 drives the two sleeves 524 to move at the same time, until the overall length of the sleeve 524 and the connecting rod 523 is adjusted to match the irradiation focus of the laser cleaning head 4, the staff then inserts the pin 522 through the corresponding positioning hole 525 and plugs it into the connecting rod 523, and finally the staff connects the air guide pipe 54 to the air inlet end of the suction fan 55, and the staff can use it normally;

[0037] When the staff turns on the fiber laser machine 2 through the tube control system 3, the fiber laser machine 2 controls the laser cleaning head 4 to emit a laser beam. The staff only needs to irradiate the focus of the laser beam on the surface of the workpiece. After the pollution layer on the surface of the workpiece absorbs the laser beam, the absorption of large energy forms a rapidly expanding plasma and generates a shock wave. The shock wave breaks the pollutants into fragments and removes them. At the same time, the suction fan 55 stirs the air and guides the air inside the air duct 54 to the inside of the operating handle 51. The air duct 54 absorbs the outside air through the installation box 531. The installation box 531 sucks the air and the smoke and dust stirred up by the laser cleaning head 4 into the installation box 531 through the air guide cover 526, so that the area around the laser cleaning head 4 is always kept clean. There is no need for the staff to remove dust while cleaning the workpiece. It can not only ensure that the laser beam can stably irradiate the surface of the workpiece, but also The workload of the staff is also reduced. When the air containing smoke and dust passes through the installation box 531, the dust filter cloth 534 can filter out the smoke and dust contained in the air, so that the clean air enters the interior of the operating handle 51 along the air duct 54, and then the suction fan 55 guides the air into the air guide hopper 562. The air guide hopper 562 guides the air into the heat-conducting copper tube 561. In the process of passing through the heat-conducting copper tube 561, the air quickly drives the heat accumulated inside the heat-conducting copper tube 561, so that the heat-conducting copper tube 561 is quickly cooled to ensure that the heat-conducting copper tube 561 can continuously absorb the heat generated by the laser cleaning head 4 during operation to ensure that the laser cleaning head 4 can operate normally, and the exhaust of the suction fan 55 is used to dissipate heat for the laser cleaning head 4, without the need to add a separate heat dissipation structure for the laser cleaning head 4, which effectively reduces the cost required for laser cleaning.

[0038] It should be noted that the fiber laser machine 2, control system 3, laser cleaning head 4, drive motor 536 and suction fan 55 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the fiber laser machine 2, control system 3, laser cleaning head 4, drive motor 536 and suction fan 55 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
