The diffused smoke and dust will pollute and affect the production environment, and will affect the health of the operators after being inhaled; 2. If a spray device is set to settle the smoke and dust to achieve the purpose of dust removal, the airflow generated by laser cutting will easily splash the sprayed water, causing the sprayed water to fall on the workpiece, affecting the cutting of the workpiece, or splashing back to the laser cutting head, causing the laser cutting head to adhere to impurities and damage the laser cutting head, affecting the cutting quality to a certain extent.

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-7 The present invention provides a technical solution: a laser cutting device for automobile parts, comprising a cutting table 3, a laser cutting mechanical arm 1, a laser cutting head 2 and a controller 11, wherein the cutting table 3 is used to place automobile parts, the laser cutting mechanical arm 1 is connected to a side wall of the cutting table 3, the laser cutting head 2 is connected to the operating end of the laser cutting mechanical arm 1, the laser cutting head 2 is located above the cutting table 3, the controller 11 is connected to the cutting table 3, the laser cutting mechanical arm 1 and the laser cutting head 2 are both electrically connected to the controller 11, and the characteristics are: The cutting table 3 includes a support portion 5, a spray mechanism 6, a fan 4 and a blocking mechanism. The upper end surface of the cutting table 3 is recessed downward to form a groove 31. The support portion 5 is slidably connected to the upper portion of the groove 31. The support portion 5 is used to support automobile parts. The spray mechanism 6 is connected to the side wall of the groove 31. The spray mechanism 6 is located below the support portion 5. The spray mechanism 6 is used to flush water under the automobile parts. The blocking mechanism is located between the support portion 5 and the spray mechanism 6. The blocking mechanism is located in the length direction of the laser emitting from the laser cutting head 2. One end of the blocking mechanism is connected to the output end of the laser cutting robot 1. The fan 4 is connected to the upper end surface of the groove 31. The fan 4 is located above the support portion 5.

[0022] When using the automobile parts cutting device of the present invention to perform laser cutting on automobile parts, first slide the support part 5 to move the support part 5 to a position matching the automobile parts, then place the automobile parts on the support part 5, so that the support part 5 supports and fixes the automobile parts, then start the fan 4 and the spray mechanism 6, and then operate the laser cutting robot arm 1, so that the laser cutting robot arm 1 drives the laser cutting head 2 to perform laser cutting on the automobile parts.

[0023] When performing laser cutting, since the fan 4 is located above the support part 5, the fan 4 can blow the smoke generated during the cutting process downward, so that the smoke in the air can fall downward onto the water curtain formed by the spray mechanism 6, and then be driven by the water flow to fall into the lower part of the groove 31. With this structure, the possibility of smoke being emitted to the workshop during cutting can be reduced to a certain extent, and the possibility of smoke falling back to the cutting table 3 and being driven by the airflow generated by the laser beam during laser cutting to fly around again can be prevented, thereby reducing the possibility of the generated smoke being inhaled by the operator to a certain extent, thereby improving the safety of the device when used.

[0024] Furthermore, since the blocking mechanism is located between the supporting part 5 and the spraying mechanism 6, the blocking mechanism is located in the length direction of the laser emitting laser by the laser cutting head 2, and one end of the blocking mechanism is connected to the output end of the laser cutting robot 1, the blocking mechanism can block the airflow generated by the laser cutting head 2, thereby reducing the possibility that the airflow generated by the laser cutting head 2 impacts the surface of the water curtain, thereby causing the water flow to splash onto the surface of automotive parts or the laser cutting head, thereby ensuring the cutting quality to a certain extent.

[0025] In this embodiment: a drain outlet 63 is formed at the bottom of the groove 31, and the spray mechanism 6 includes a water divider 61, a spray nozzle 62 and a water pump 64. The water divider 61 is arranged along the length direction of the groove 31, and there are multiple spray nozzles 62. The multiple spray nozzles 62 are arranged at intervals along the length direction of the groove 31, and the multiple spray nozzles 62 are all connected to the water divider 61. The water inlet of the water pump 64 is connected to the drain outlet 63, and the water outlet of the water pump 64 is connected to the water inlet of the water divider 61. Water is added to the groove 31, and the water is pumped out by the water pump 64 and introduced into the water divider 61 and sprayed out from the spray nozzle 62 to form a water curtain; the water curtain will wet the smoke and dust blown off by the fan 4 so that it will settle and finally fall into the lower part of the groove 31 with the water flow, and the water falling into the groove 31 can be pumped out by the water pump 64 and enter the water divider 61 again to form a water curtain. With this structure, the water used to settle the smoke and dust can be pumped out by the water pump 64 after falling into the groove 31 and used again for the formation of the water curtain, thereby realizing the recycling of water resources and saving water resources to a certain extent.

[0026] In this embodiment: the blocking mechanism includes a slide rail 121, a rotating shaft 122, a baffle 123, a connecting rod 124 and a telescopic rod 125, the slide rail 121 is arranged between the water divider 61 and the support part 5, the slide rail 121 is arranged along the length direction of the groove 31, the rotating shaft 122 is arranged along the width direction of the groove 31, the rotating shaft 122 is slidably connected to the slide rail 121, the baffle 123 is arranged perpendicular to the width direction of the groove 31, one end of the baffle 123 is fixedly connected to the lower end of the connecting rod 124, the lower part of the connecting rod 124 is rotatably connected to the rotating shaft 122, the telescopic rod 125 is arranged parallel to the baffle 123, one end of the telescopic rod 125 is hinged to the upper end of the connecting rod 124, and the other end of the telescopic rod 125 is ball-jointed to the output end of the laser cutting robot arm 1.

[0027] Since the rotating shaft 122 is slidably connected to the slide rail 121, one end of the baffle 123 is fixedly connected to the lower end of the connecting rod 124, and the telescopic rod 125 is arranged parallel to the baffle 123. One end of the telescopic rod 125 is hinged to the upper end of the connecting rod 124, and the other end of the telescopic rod 125 is ball-jointed to the output end of the laser cutting robot 1. When the laser cutting robot 1 moves in the horizontal direction, the baffle can be translated along the position of the output end of the laser cutting robot 1, so that the position of the laser cutting head 2 can correspond to the position of the baffle 123.

[0028] Since the lower part of the connecting rod 124 is rotatably connected to the rotating shaft 122, when the laser cutting head 2 performs bevel cutting of automobile parts, the baffle 123 can rotate with the angular rotation of the output end of the laser cutting robot 1, so that the baffle 123 is always located in the length direction of the laser emitting laser of the laser cutting head 2.

[0029] In this embodiment: the baffle 123 includes a plate body 1231 and a light-transmitting sheet 1232, the upper end surface of the plate body 1231 is recessed to form a receiving groove, the light-transmitting sheet 1232 is cooperatively connected to the upper part of the receiving groove, and a light sensor is provided between the bottom wall of the receiving groove and the light-transmitting sheet 1232, the light sensor is electrically connected to the controller 11, the water pump 64 is electrically connected to the controller 11, and the light sensor controls the start and stop of the water pump 64 through the controller 11.

[0030] When the automobile parts cutting device of the present invention performs laser cutting on automobile parts, the laser emitted by the laser cutting head 2 will pass through the cut gap to reach the light-transmitting sheet 1232. The light-transmitting sheet 1232 can be made of high-purity silicon dioxide crystals. When the laser passes through the light-transmitting sheet 1232, the optical signal is transmitted to the optical sensor, which is converted into an electrical signal by the optical sensor and transmitted to the controller 11, so that the controller 11 controls the operation of the water pump 64, so that the spray mechanism 6 can produce a water curtain; after stopping cutting, the optical sensor no longer receives the laser signal, and stops transmitting the signal to the controller 11, so that the water pump 64 also stops running.

[0031] With this structure, a water curtain will be formed simultaneously during laser cutting, preventing the operator from forgetting to open the water curtain, thereby reducing the possibility of ineffective dust removal.

[0032] In this embodiment: the spray mechanism 6 also includes an impeller 65, a first bevel gear 66 and a second bevel gear 67, the impeller 65 is connected to the water outlet of the water pump 64, the first bevel gear 66 is connected to the impeller 65, the rotation centerline of the first bevel gear 66 is on the rotation centerline of the impeller 65, the second bevel gear 67 is connected to the fan 4, the rotation centerline of the second bevel gear 67 is on the rotation centerline of the fan 4, and the first bevel gear 66 is meshed with the second bevel gear 67.

[0033] The water in the groove 31 is extracted by the water pump 64, and flows out from the water outlet of the water pump 64, forming a one-way water flow at the water outlet of the water pump 64. Since the impeller 65 is connected to the water outlet of the water pump 64, the first bevel gear 66 is connected to the impeller 65, and the rotation center line of the first bevel gear 66 is on the rotation center line of the impeller 65. The water flow drives the impeller 65 to rotate, thereby driving the first bevel gear 66 to rotate. Since the first bevel gear 66 is meshed with the second bevel gear 67, the first bevel gear 66 can drive the second bevel gear 67 to rotate. Since the second bevel gear 67 is connected to the fan 4, the rotation center line of the second bevel gear 67 is on the rotation center line of the fan 4, and the rotation of the second bevel gear 67 can drive the fan 4 to rotate.

[0034] With this structure, when the water pump 64 is started to make the spray mechanism 6 spray water to form a water curtain, the fan 4 can also be operated at the same time to blow off the floating smoke and dust, converting the kinetic energy of the water flow into the kinetic energy of the fan operation. The fan 4 and the water pump 64 can be started and stopped at the same time, saving energy to a certain extent.

[0035] In this embodiment: the support part 5 includes a first electromagnetic slide rail 51 and a support assembly. The first electromagnetic slide rail 51 is arranged along the length direction of the groove 31. There are two first electromagnetic slide rails 51. The two first electromagnetic slide rails 51 are oppositely arranged on two opposite side walls of the groove 31. There are multiple support assemblies. The multiple support assemblies are slidably connected to the two first electromagnetic slide rails. The support assembly includes a first electromagnetic slider 53, a second electromagnetic slider 52, a second electromagnetic slider 54, an electric telescopic rod 55 and an electromagnetic suction cup 56. There are two first electromagnetic sliders 53. The two first electromagnetic sliders 53 are slidably connected to the first electromagnetic slide rails 51 in a one-to-one manner. The second electromagnetic slide rail 52 is arranged perpendicular to the two first electromagnetic slide rails 51. The two ends of the second electromagnetic slide rail 52 are respectively connected to the two first electromagnetic sliders 53. There are multiple second electromagnetic sliders 54. The multiple second electromagnetic sliders 54 can be slidably connected to the second electromagnetic slide rail 52; the upper end surface of the second electromagnetic slider 54 is fixedly connected to the lower end of the electric telescopic rod 55, and the electromagnetic suction cup 56 is ball-jointed to the upper end of the electric telescopic rod 55.

[0036] The first electromagnetic slide rail 51, the first electromagnetic slider 53, the second electromagnetic slide rail 52, the second electromagnetic slider 54, the electric telescopic rod 55 and the electromagnetic suction cup 56 are all electrically connected to the controller. By operating the controller to make the first electromagnetic slider 53 slide on the first electromagnetic slide rail 51, the support assembly can be made to slide along the length direction of the groove 31. By operating the controller to make the support assembly slide on the second electromagnetic slide rail 52, the support assembly can be made to slide along the length direction perpendicular to the groove 31. With this structure, the support assembly can be made to slide arbitrarily on the cutting table 3, so that the support assembly can be adjusted. , so that the support part 5 can support automobile parts of more shapes; by operating the controller to extend and retract the electric telescopic rod 55, the height of the support assembly can be matched with the curved shape of the automobile part, so that when the support part 5 supports the thin-walled automobile part, the surface of the thin-walled automobile part will not be dented due to lack of support, thereby ensuring the accuracy of laser cutting; after adjusting the electric telescopic rod 55 to a suitable height, the automobile part to be cut is placed on the support part 5, and by operating the controller to make the electromagnetic suction cup 56 adsorb the inner wall of the automobile part, the automobile part can be more firmly connected to the support part 5.

[0037] In this embodiment: the fan 4 includes a fan 42, a bellows 43 and an air outlet 41, the fan 42 is connected to the second bevel gear 67, the fan 42 is located in the bellows 43, the bellows 43 is arranged along the length direction of the groove 31, the bellows 43 is connected to the upper end surface of the groove 31, the bellows 43 is formed with an air outlet 41, the air outlet 41 is arranged along the length direction of the groove 31, the air outlet 41 faces the inside of the groove 31, the support portion 5 also includes a baffle 44, there are two baffles 44, the two baffles 44 are respectively arranged on the two support components at the outer ends on both sides in the arrangement direction of the plurality of support components, the two baffles 44 are both located in the bellows 43, the two baffles 44 are both arranged vertically, the fan 4 is located between the two baffles 44, and the two baffles 44 partition the inside of the bellows 43.

[0038] When the support portion 5 is used to support automobile parts, the two support assemblies at the outer ends on both sides in the arrangement direction of the multiple support assemblies are supported on the outermost ends of the automobile parts. Since the two baffles 44 are respectively arranged on the two support assemblies at the outer ends on both sides in the arrangement direction of the multiple support assemblies, the fan 4 is located between the two baffles 44, and the two baffles 44 partition the inside of the bellows 43. The two support assemblies at the outer ends on both sides in the arrangement direction of the multiple support assemblies can be moved to adjust the air outlet position and range of the fan 4, so that it can more efficiently blow away the smoke generated by the cutting part of the automobile parts.

[0039] In the present embodiment, a supporting portion is also included, and the supporting portion includes a supporting block 91 and a spring 92. The supporting block 91 has inclined surfaces formed on both side surfaces along the length direction of the groove 31 toward an edge of the water divider 61. The two ends of the spring 92 are respectively connected to the supporting block 91 and the outermost supporting component at one end in the arrangement direction of the plurality of supporting components. The water divider 61 includes a rotary switch 93, and the supporting block 91 resists the rotary switch 93.

[0040] When the outermost support assembly at one end in the arrangement direction of the plurality of support assemblies moves toward the middle of the groove 31, the abutting portion abuts the rotation switch 93 to rotate, thereby closing the rotation switch 93 and preventing the water flow from flowing from this position to the position of the next spray nozzle 62; when the outermost support assembly at one end in the arrangement direction of the plurality of support assemblies moves away from the middle of the groove 31, the abutting portion abuts the rotation switch 93 to rotate, thereby opening the rotation switch 93 and allowing the water flow to flow through this position to the position of the next spray nozzle 62; with this structure, the width of the water curtain can be adjusted according to the cutting size of the automotive parts, and the movement of the outermost support assembly in the arrangement direction of the plurality of support assemblies can simultaneously control the blowing area of ​​the fan 4 to be consistent with the water curtain forming area.

[0041] Specifically, when the abutting portion moves to the position of the rotary switch 93, the abutting block 91 abuts against the rotating end surface of the rotary switch 93. Since the two side surfaces of the abutting block 91 along the length direction of the groove 31 are close to each other toward an edge of the water divider 61 to form an inclined surface, when the abutting block 91 pushes the rotary switch 93 to rotate closed or open, the switch stops rotating. Thereafter, the inclined surface pushes the abutting block 91 in the direction away from the water divider 61 under the push of the rotary switch 93. Since the two ends of the spring 92 are respectively connected to the abutting block 91 and a plurality of On the outermost support component at one end in the arrangement direction of the support components, the supporting block 91 will push the spring 92 to compress, so that the supporting block 91 gradually moves away from the rotating switch 93 and passes through the rotating switch 93. After the supporting block 91 passes through the rotating switch 93, the rotating switch 93 releases the thrust on the inclined surface, so that the supporting block 91 ends the thrust on the spring 92. The spring 92 drives the supporting block 91 to reset without being pushed, until it passes the next rotating switch 93, and the supporting portion resists the next rotating switch 93 again.

[0042] In the present embodiment: it also includes a plurality of filter plates 7 and a plurality of slag boxes 8, the apertures of the plurality of filter plates 7 are arranged to decrease gradually from top to bottom, the plurality of filter plates 7 are connected to the side wall of the groove 31, the plurality of filter plates 7 are located below the spray nozzle 62, a section of the plurality of filter plates 7 are arranged to be tilted downward, the plurality of slag boxes 8 are connected one by one to one end of the plurality of filter plates 7 tilted downward, the vibrator 13 is connected to the filter plate 7, and the vibrator 13 is connected to the controller 11.

[0043] After the automobile parts are cut by the automobile parts cutting device of the present invention, the slags falling down are filtered by the filter plates 7 arranged from large to small apertures, so that slags of different sizes can be separated and collected for easy recycling.

[0044] Specifically, the filter plate 7 includes a first filter plate 71, a second filter plate 72 and a third filter plate 73. The first filter plate 71 is used to filter larger pieces of slag, the second filter plate 72 is used to filter smaller pieces of slag, and the third filter plate 73 is used to filter metal mud formed by metal smoke in water. Since the vibrator 13 is connected to the filter plate 7, the controller 11 receives the light signal of the light sensor 11 and sends an electrical signal to the vibrator 13 through the controller 11, so that the vibrator 13 vibrates, thereby reducing the possibility of metal mud or slag accumulation at the filter plate 7, thereby reducing the possibility of clogging the filter holes and affecting the water flow to reach the drain outlet 63.

[0045] The cut slag will fall onto the inclined surface of the filter plate 7, and then slide through the inclined surface into the multiple slag boxes 8. With this structure, there is no need for operators to manually separate and collect them, which reduces the workload of operators to a certain extent.

[0046] Specifically, the slag box 8 includes a first slag box 81 and a second slag box 82. The first slag box 81 is connected to a downwardly inclined end of the first filter plate 717, and the second slag box 82 is connected to a downwardly inclined end of the second filter plate 72. With this structure, the slag can be collected separately.

[0047] In this embodiment: it also includes a cleaning mechanism, which includes a push plate 101, a threaded rod 102 and a motor 103. The push plate 101 is arranged along the length direction of the filter plate 7, and the lower end surface of the push plate 101 abuts against the upper end surface of the filter plate 7. The threaded rod 102 is arranged parallel to the length direction of the filter plate 7. The push plate 101 is provided with a screw hole, and the threaded rod 102 is screwed into the screw hole. The motor 103 is electrically connected to the controller 11, and the controller 11 is used to control the rotation of the motor 103 when the optical sensor does not receive the laser signal.

[0048] After the controller 11 does not receive the light signal from the light sensor, the controller 11 controls the control motor 103 to rotate forward and reverse, causing the threaded rod 102 to rotate forward and reverse, thereby driving the push plate 101 to make a reciprocating motion along the length direction of the filter plate 7, so that the push plate 101 pushes the slag on the filter plate 7 into the slag box 8 and then resets, and continues to reciprocate until the next cutting operation. With this structure, the operator does not need to manually clean the slag after cutting, which reduces the operator's workload to a certain extent.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
