Description

Technical Field

[0001] The invention relates to the technical field of high-power galvanometers, in particular to a high-power galvanometer with a dustproof mechanism. Background Art

[0002] High-power galvanometers mainly work based on the principle that an energized coil generates torque in a magnetic field. The special feature is that a restoring torque is added to the rotor through a mechanical spring or electronic method, and the magnitude is proportional to the angle at which the rotor deviates from the equilibrium position. When a certain current is passed through the coil and the rotor deflects to a certain angle, the electromagnetic torque is equal to the restoring torque, so that the rotor can only deflect, and the deflection angle is proportional to the current. Similar to an ammeter, it is widely used in laser welding, laser marking, laser cutting and other fields. When a high-power galvanometer is used for processing at the processing site, a large amount of smoke and dust will be generated, which will affect the processing efficiency due to obstructed vision. The smoke generated during high-power galvanometer processing must be cleaned in time.

[0003] The existing high-power galvanometer will generate a lot of smoke when in use, which needs to be cleaned in time to ensure the welding line of sight or the recognition of the infrared laser sensor, and will not affect the processing path due to the smoke. Therefore, it is necessary to deal with the smoke when the high-power galvanometer is used. For example, a dust protection device for a laser welding machine disclosed in publication number CN218476157U includes a workbench, the upper surface of the workbench is fixedly connected to the welding table and the hydraulic cylinder, the hydraulic cylinder is located on the rear side of the welding table, the upper end of the hydraulic cylinder is fixedly connected to a cross plate, the lower surface of one end of the cross plate is fixedly connected to a dust box, the inner wall of the dust box is fixedly connected to the welding head, dust collecting mechanisms are provided on both sides of the welding head, the rear inner wall of the dust box is fixedly connected to an air box, the front surface of the air box is fixedly connected to multiple groups of nozzles, and the upper surface of the welding table is provided with a limiting mechanism. While collecting the dust inside the dust cover on the laser cutting machine, the dust inside the dust cover can be continuously lifted up to prevent heavier dust from falling and accumulating on the laser cutting machine, thereby improving the dust collection effect of the dust protection device, preventing dust from accumulating on the laser cutting machine and causing failure, and extending the service life of the laser cutting machine; and, for example, a protective cover for a laser welding machine disclosed in application number CN209223423U, the protective cover for the laser welding machine has two protective cavities with downward openings, one of which has a receiving space larger than the workbench of the laser welding machine, and is used to cover the workbench of the laser welding machine to protect it, and the other protective cavity has a receiving space larger than the operating table of the laser welding machine, and is used to cover the operating table of the laser welding machine to protect it. The two protective cavities can effectively protect the workbench and the operating table of the laser welding machine respectively, and have the effect of dustproof, rainproof and moisture-proof. However, these two solutions do not further solve the cleaning of dust or solid objects in the dust cover, and the dust cover cannot be further cleaned. Incomplete cleaning of the dust cover will also affect the efficient use of the galvanometer. Summary of the invention

[0015] The present invention also discloses a high-power galvanometer with a dustproof mechanism, which uses the high-power galvanometer with a dustproof mechanism, and includes the following steps:

[0016] Compared with the related art, the present invention has the following beneficial effects:

[0017] 1. The present invention adds a dust cover to the outside of the high-power galvanometer to centrally suck out the dust and mist during the processing and use of the galvanometer, so as to always keep the galvanometer efficient and the working environment clean during use. Due to the design of the dust cover and the special dust and mist channel, the dust and mist during processing are discharged through the specific dust and mist channel, and a filter is installed at the entrance of the dust and mist channel to filter the dust and mist, so that the smoke discharged into the air will not cause a bad environment.

[0018] 2. The present invention designs a rotating cleaning part on the surface of the filter to continuously scrape, brush, and apply an anti-static oil film to the lint or solid objects on the filter that are not easy to be sucked out, so that the solids that are difficult to clean are hung up, and then a layer of anti-static oil film is applied to the filter, so that the filter will not adsorb solids or lint again due to static electricity, thereby extending the service life and cleaning cycle of the filter, and when there are too many particles accumulated on the filter, the particles will not fall onto the workpiece during use, thereby not affecting the cleanliness of the surface of the welded workpiece, thereby ensuring the stability of the workpiece welding.

[0019] 3. The present invention cleans the lint and solid matter on the filter screen by rotating the cleaning part. At the same time, the excess oil film in the process of applying the oil film to the filter screen may be collected along the dripping oil film of the filter screen. The collected oil film is recycled and supplied to the anti-static oil film plate from the feeding channel again. The recycling is more environmentally friendly. At the same time, the secondary contamination of the galvanometer by the dripping oil film is avoided, thereby ensuring the stability of subsequent welding.

[0020] 4. The present invention collects the oil film materials collected in the anti-leakage groove in a centralized manner through the arrangement of the oil storage film device and the internal sponge, which does not result in a large amount of excess oil film being left unprocessed and causing contamination in the dust cover. In addition, there is a height difference between the oil inlet and oil outlet positions in the oil storage film device, so the oil film materials can be reused and transported outward more smoothly. In addition, due to the arrangement of the extrusion plate on the oil storage film device, the pressure exerted on the extrusion plate is converted into the pressure of the internal pressure of the oil storage film device, so that the stored oil film materials can be smoothly output. At the same time, the oil inlet can be temporarily shielded and blocked, so that the extrusion plate will not be contaminated by the oil inlet, and the extrusion plate and the spring can be kept clean.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0037] See also Figure 1-Figure 11A high-power galvanometer with a dust-proof mechanism comprises a galvanometer body 1, a welding head 2, a mounting portion 3, an exhaust fan 4 and a dust cover 5. The galvanometer body 1 comprises a welding head 2, a mounting portion 3 and an exhaust fan 4. The welding head 2 can directly contact the processing part. The mounting portion 3 can be fixed with an external connecting rod by bolts. The exhaust fan 4 is installed on the dust cover 5 by bolts. The dust cover 5 is fixedly sleeved outside the welding head 2. A dust and mist channel 501 is provided in the dust cover 5. The outlet of the dust and mist channel 501 faces the exhaust fan 4. A filter screen 502 is installed at the inlet direction of the dust and mist channel 501. The dust cover 5 protects the welding head 2 and can quickly absorb the dust and mist when the welding head 2 is in use or process it in time within the range of the dust cover 5. The dust cover 5 is a rectangular hollow structure. , a motor 6 is fixedly installed on the inner wall of the dust cover 5, a reciprocating screw rod 601 is connected to the motor 6, a limiting sleeve 602 is sleeved on the reciprocating screw rod 601, the bottom of the limiting sleeve 602 is slidably connected to the limiting rod 603, and the top of the limiting sleeve 602 is fixedly connected to the suction groove 9, so that the rotation of the motor 6 and the reciprocating movement of the suction groove 9 along the direction of the reciprocating screw rod 601 drive the dust cover 5 to be provided with a vacuum pump 7 at the bottom, and the vacuum pump 7 is connected to the bottom of the suction groove 9 through a hose 701. A plurality of suction holes 901 are opened in the suction groove 9, and a rotating cleaning part 8 is provided at the edge of each suction hole 901. When the suction groove 9 moves back and forth, the dust mist in the dust cover 5 due to the processing of the welding head 2 is discharged along the dust mist channel 501, and the dust on the filter screen 502 is sucked;

[0038] A rack 503 is fixedly provided on the inner wall side of the dust cover 5, and a gear 504 is meshingly connected to the rack 503. The axis of the gear 504 is coaxial with the main shaft 801, and its axis passes through the fixed ring 505. The fixed ring 505 is fixedly connected to the inner side of the suction groove 9. The rotation of the gear 504 drives the rotation of the main shaft 801 and the rotating shaft 802. Under the limiting effect of the fixed ring 505, the main shaft 801 always keeps rotating and keeps a fixed distance from the suction groove 9.

[0039] The dust and mist passage 501 and the filter 502 are arranged perpendicularly to each other, and there are multiple filters 502, and each filter 502 is provided with a rotating cleaning part 8. Each rotation of the rotating cleaning part 8 can remove the fluff on the filter 502 once, and apply a layer of anti-static oil film to prevent a large amount of fluff from being adsorbed and accumulated on the filter 502.

[0040] The length of the suction groove 9 is adapted to the width of the dust cover 5 , and the reciprocating screw rod 601 and the suction groove 9 are in a cross shape, and the two ends of the reciprocating screw rod 601 are respectively connected to the motor 6 and the inner wall of the dust cover 5 .

[0041] First, when the welding head 2 is used, there will be a large amount of smoke, dust and other dust, which will be transported outward with the operation of the exhaust fan 4 to keep the welding head 2 in an efficient and clean state during processing. (In the process of transporting the dust and mist to the outside of the exhaust fan 4, a large amount of hair will be filtered by the filter 502, which is difficult to clean). In the process of sucking the dust and mist inside the dust cover 5, the hair or solid matter on the surface of the filter 502 is difficult to clean, and further scraping, brushing and other operations are required. Embodiment 2

[0042] like Figure 4-Figure 6 As shown, the rotating cleaning part 8 includes a main shaft 801, a rotating shaft 802 fixedly connected to the main shaft, a scraper 803 fixedly connected to one of the rotating shafts 802 and a static oil film removing sponge plate 804 installed on the other, the height of the scraper 803 is flush with the height of the filter 502, and the fluff on the filter 502 that is not easily sucked out can be brushed off by the brush on the scraper 803, achieving the effect of hanging and smearing at one time.

[0043] Secondly, the output end of the vacuum pump 7 is connected to the external filter bag through a pipeline, so that the vacuum pump 7 transports the sucked fluff and dirt into the filter bag for centralized collection. The rotation of the output end of the motor 6 drives the operation of the reciprocating screw 601, and under the limiting action of the limit sleeve 602 and the limit rod 603, the reciprocating screw 601 drives the suction groove 9 to move back and forth along the direction of the reciprocating screw 601, so that the suction hole 901 in the suction groove 9 continuously sucks back and forth in the direction of the filter screen 502 to clean the dust adsorbed on the filter screen 502. The coordination of the rack 503 and the gear 504 drives the rotation of the gear 504, so that the entire rotating cleaning part 8 rotates, and the scraper 803 continuously cleans the fluff or solid matter on the surface of the filter screen 502 during the rotation. Embodiment 3

[0044] like Figure 7-Figure 11 As shown, a knocking ball 805 is also sleeved on the main shaft 801, and the end of the knocking ball 805 can contact the protrusion on the extrusion plate 806 to squeeze the extrusion plate 806 downward. The bottom surface of the extrusion plate 806 is fixedly connected to multiple groups of springs 807, and the bottom end of the spring 807 is fixedly connected to the baffle 808.

[0045] An oil storage film device 813 is fixedly connected to the inner side of the suction groove 9, and a liquid outlet 809 is opened inside the oil storage film device 813 to penetrate to the outside. The liquid outlet 809 is connected to one end of a liquid outlet pipe 810, and the other end of the liquid outlet pipe 810 penetrates through the sleeve 811 and is transported to the axis of the rotating shaft 802 and the main shaft 801, and is transported to the feeding channel 812 in the static electricity removal oil film sponge plate 804 on both sides of the rotating shaft 802 without affecting the rotation of the rotating shaft 802. At the same time, the oil film is recycled and supplied to the static electricity removal oil film sponge plate 804 again.

[0046] The liquid outlet pipe 810 is installed on the oil storage film device 813, and the oil storage film device 813 is also connected to one end of the liquid inlet pipe 814. The other end of the liquid inlet pipe 814 is connected to the lower end of the leakage-proof groove 815 along the inner wall of the suction groove 9. The leakage-proof groove 815 is inclined in the suction groove 9, and its length is adapted to the width of the suction groove 9. When the anti-static oil film sponge plate 804 is applied to the filter screen 502 with an oil film, the excess oil film can be collected by the leakage-proof groove 815 for recycling (the overlapping part of the leakage-proof groove 815 and the main shaft 801 is a thinner shaft, and the diameter of the thinner shaft is one-fourth of the diameter of the main shaft 801. The main shaft 801 is driven to rotate as a whole at the bottom of the leakage-proof groove 815. The rotation of the main shaft 801 is relatively independent, and the use environment of the leakage-proof groove 815 is also independent).

[0047] When the baffle 808 moves downward, the liquid inlet pipe 814 is temporarily blocked to prevent the oil in the liquid inlet pipe 814 from flowing to the top of the baffle 808, and at the same time, the oil film collected in 816 can be smoothly output to 810.

[0048] The oil storage film device 813 is fixedly arranged next to the suction hole 901 of the suction groove 9. A sponge 816 with a volume that matches half of the oil storage film device 813 is arranged at the bottom of the oil storage film device 813. The sponge 816 is filled with the anti-static oil film. When the sponge 816 is squeezed, the internal anti-static oil film is squeezed to transport the oil film toward the liquid outlet pipe 810.

[0049] The height of the liquid inlet pipe 814 is higher than that of the liquid outlet pipe 810. The excess oil film dripping from the filter screen 502 collected in the liquid inlet pipe 814 is transported toward the liquid outlet pipe 810 again, and the height difference makes it easier to squeeze out the oil film.

[0050] Finally, as the gear 504 rotates, the rotating cleaning part 8 and the main shaft 801 are driven to rotate, and the scraper 803 and the anti-static oil film sponge plate 804 are driven to rotate continuously (so that the surface of the filter 502 is scraped and wiped and coated with an oil film). When the main shaft 801 and the rotating shaft 802 rotate once, the knocking ball 805 is driven to rotate once, and the squeezing plate 806 is squeezed once (under the action of the baffle 808, it can squeeze downward and rebound upward to reset), and the oil film in the sponge 816 is supplied to the liquid outlet pipe 810, and the anti-static oil film sponge plate 804 is continuously supplied, so that the anti-static oil film sponge plate 804 continuously wipes the filter 502 while continuously applying the anti-static oil film (the anti-static oil film is effective in preventing dust from being adsorbed due to static electricity, slowing down the time of dust adsorption, and extending the service life of the filter 502).

[0051] The oil film storage device 813 can make the excess oil film drip into the anti-leakage groove 815 when the anti-static oil film sponge plate 804 wipes the oil film on the filter 502, and collect it centrally, and the sponge 816 in the oil film storage device 813 is continuously supplied with oil film material.

[0052] Here’s how it works:

[0053] When the galvanometer body 1 is used, a large amount of smoke or dust will be generated when the galvanometer body 1 processes the workpiece. The smoke or dust needs to be cleaned up quickly and timely to ensure efficient processing of the galvanometer body 1. Under the action of the exhaust fan 4, the smoke or dust will pass through the dust cover 5 and be transported outward along the dust channel 501, and will be filtered by the filter 502 during the transportation process;

[0054] The long-term use of the filter 502 will cause a large amount of lint or solid matter to accumulate, which is not easy to be cleaned, and is also likely to affect the service life of the filter 502 and the smoke exhaust effect in the dust cover 5, so the lint and solid matter of the filter 502 need to be cleaned in time;

[0055] The cleaning method is to rely on the operation of the motor 6 to drive the operation of the reciprocating screw 601, so that the limit sleeve 602 and the limit rod 603 reciprocate back and forth in the direction of the reciprocating screw 601, drive the suction groove 9 to move back and forth, and use the suction hole 901 to suck the vicinity of the filter screen 502 to assist in cleaning the lint or solid matter on the filter screen 502;

[0056] When the suction groove 9 moves back and forth, it drives the synchronous operation of the fixed ring 505, rotates the gear 504 on the rack 503, and the rotation of the rack 503 drives the rotation of the main shaft 801 and the rotating shaft 802, so as to realize the rotation of the scraper 803 and the anti-static oil film sponge plate 804. The one-time rotation of the scraper 803 and the anti-static oil film sponge plate 804 can scrape the fluff on both sides of the surface of the filter screen 502 and apply the anti-static oil film, and the scraped fluff is processed in the suction pump 7 along the suction hole 901 and the hose 701 on the suction groove 9;

[0057] The application of the anti-static oil film to the filter 502 may cause the risk of excess oil film dripping, which may easily pollute the suction tank 9. Therefore, the anti-leakage tank 815 is required to collect and centrally collect the excess oil film. Due to the inclined setting of the anti-leakage tank 815, the excess dripping oil film can be transported toward the direction of the liquid inlet pipe 814, transported to the oil film storage device 813, and absorbed again by the sponge 816.

[0058] At the same time, the rotation of the main shaft 801 and the rotating shaft 802 also drives the rotation of the knocking ball 805. The rotation of the knocking ball 805 will squeeze the squeezing plate 806, and squeeze it once for one rotation. When the squeezing plate 806 is squeezed and moves downward, the spring 807 is squeezed, and the baffle 808 is driven to move downward. Since the baffle 808 is an L-shaped plate, the baffle 808 moves downward to temporarily block and block the liquid inlet pipe 814, so that the original oil inlet state is suspended, and the baffle 808 and the spring 807 will not be polluted due to the continuous oil inlet.

[0059] The sponge 816 in the oil film storage device 813 will also transport the oil film toward the liquid outlet pipe 810 due to the change of internal pressure due to one squeezing, and transport the oil film to the feeding channel 812, so as to achieve the effect of continuously supplying the oil film to the anti-static oil film sponge plate 804;

[0060] A rotating cleaning part 8 is provided near each air extraction hole 901 to clean the filter 502 back and forth. Each filter 502 can be cleaned well, achieving the purpose of batch and efficient cleaning, and better protecting the galvanometer body 1 during processing.

[0061] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
