Laser cutting processing is gradually replacing traditional tools. Optical micromachining is widely used in cutting various materials due to its high processing efficiency, less cutting residue, non-contact processing, and easy automation of the processing process. Laser cutting uses a high-power density laser beam to scan the surface of the material, heating the material to several thousand to tens of thousands of degrees Celsius in a very short time, melting or vaporizing the material, and then blowing the melted or vaporized material away from the cut to achieve the purpose of cutting the material.

Even if the finished product that falls to the top of the separation box first slides on the inclined surface of the separation box, the finished product cannot affect the process of the remaining circular pads entering the separation box. Multiple circular pads enter the separation box, and finally the cut finished product falls to the top of the separation box, and under the action of the inclined surface at the top of the separation box, it falls into the two material receiving boxes arranged on both sides of the separation box.

DETAILED DESCRIPTION

[0033] 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.

[0034] Example: Figure 1-Figure 13 As shown, the present invention provides a technical solution for a laser cutting machine with an automatic feeding structure, including a support beam 1, an industrial robot 2 and a laser cutting device 3, a conveying structure 4 is arranged at the bottom of the laser cutting device 3, and a support structure 5 is arranged at the bottom of the conveying structure 4; the support structure 5 includes a collecting box 51 and a separation box 53 fixedly connected to the collecting box 51, a moving plate 57 arranged inside the separation box 53, a supporting assembly arranged at the bottom of the moving plate 57, a plurality of spring telescopic rods 55 fixedly installed on the top of the moving plate 57 and a transmission assembly arranged on one side of the supporting assembly, push plates 524 are arranged on both sides of the top of the separation box 53, and the transmission assembly is connected to the two push plates 524.

[0035] Specifically, the industrial robot 2 is installed on the support beam 1, and the industrial robot 2 moves outside the support beam 1. The laser cutting equipment 3 is installed at the end of the industrial robot 2 to cut the plate transported on the conveying structure 4 that passes through the support beam 1. A support structure 5 is arranged at the bottom of the conveying structure 4, and the support structure 5 is used to support the plate.

[0036] In the present application, the conveying structure 4 includes two supporting side panels 41 symmetrically arranged on both sides of the top of the collecting box 51, and a supporting bottom plate 44 is fixedly installed at the bottom of the two supporting side panels 41. The setting of the supporting bottom plate 44 prevents the conveyor belt 45 from being damaged by the supporting structure 5 when the supporting structure 5 is working. A supporting side plate 42 is arranged on the side of the top of the supporting bottom plate 44 away from the supporting side plate 41, and a plurality of mounting shafts 43 are fixedly installed between the supporting side plate 42 and the supporting side plate 41. The setting of the mounting shafts 43 ensures that there is a certain distance between the supporting side plate 42 and the supporting side plate 41, thereby providing sufficient working space for the conveyor belt 45 installed between the supporting side plate 41 and the supporting side plate 42.

[0037] A supporting side plate three 46 is fixedly connected to one side of the bottom of the two supporting base plates 44, and a mounting frame 48 arranged between the two supporting side plates three 46 is fixedly connected to the collecting box 51. The mounting frame 48 and two guide shafts 47 fixedly penetrated on the mounting frame 48 cannot move, and both ends of the guide shaft 47 respectively pass through the two supporting side plates three 46. The two supporting side plates three 46 can only move left and right under the support and limit of the two guide shafts 47. The two supporting base plates 44 and the two conveyor belts 45 are supported to move left and right but not up and down.

[0038] The other side of the bottom of the two supporting bottom plates 44 is fixedly connected to a supporting side plate 49, and the two supporting side plates 49 are fixedly connected to a rack 410. One end of the rack 410 fixed to the left supporting side plate 49 passes through the right supporting side plate 49, and one end of the rack 410 fixed to the right supporting side plate 49 passes through the left supporting side plate 49. Therefore, when the rack 410 transmits power to the fixed supporting side plate 49, it will not affect the movement of the other supporting side plate 49. The movement between the two supporting side plates 49 The forward and reverse motor 412 arranged in the middle is fixedly installed on the collection box 51, and two guide shafts 413 are fixedly connected on both sides of the forward and reverse motor 412. The guide shaft 413 penetrates the adjacent supporting side plate 49 at one end away from the forward and reverse motor 412, and the supporting side plate 49 supported by the guide shaft 413 can only move left and right; with the cooperation of four guide shafts 413, two supporting side plates 49, two guide shafts 1 47, two supporting side plates 3 46 and other structures, the two conveyor belts 45 can move left and right.

[0039] When laser cutting of plates of different sizes is required, the forward and reverse motor 412 is controlled to work forward or reverse, and the gear 411 fixedly connected to the output end of the forward and reverse motor 412 rotates clockwise or counterclockwise. Since the gear 411 is arranged between the two racks 410 and meshes with the two racks 410, the rotating gear 411 drives the two meshing racks 410 to move, so that the two supporting side plates 49 move synchronously toward the gear 411 or move synchronously away from the gear 411, so that the interval between the two conveyor belts 45 is reduced or expanded. The conveyor belt 45 can transport plates of different sizes to meet the needs of processing a variety of plates.

[0040] After the two conveyor belts 45 working at the same speed and in the same direction move the plate to the top of the collection box 51, the plate enters the processing position, the conveyor belts 45 are controlled to stop working, and the separation box 53 fixedly connected inside the collection box 51 is set at the bottom of the plate to receive the finished products cut from the plate by the laser cutting equipment 3.

[0041] Subsequently, the support assembly installed at the bottom of the moving plate 57 is controlled to work. The double-axis hydraulic cylinder 513 and the two telescopic rods 512 in the support assembly are fixedly connected to the bottom wall of the inner cavity of the collection box 51. At this time, the telescopic shafts on both sides of the working telescopic rods 512 are contracted. Since the outer side of the support frame 1 58 fixedly connected to the bottom of the supporting moving plate 57 is provided with four support frames 2 59, the four support frames 2 59 are distributed in groups of two on both sides of the support frame 1 58, and the support frame 3 510 rotatably connected between the two support frames 2 59 on the same side is There is a support frame four 511 rotatably connected, and a double-axis hydraulic cylinder 513 is fixedly connected between the support frame four 511 rotatably sleeved at one end of one support frame three 510 and the support frame four 511 rotatably sleeved at one end of the other support frame three 510. The working and contracting double-axis hydraulic cylinder 513 pulls the two fixed support frames four 511 to move toward a position close to the support frame one 58, and the two support frames three 510 move toward a position close to the support frame one 58. Since the transmission point position between the support frame two 59 rotatably connected to the support frame three 510 and the moving plate one 57 is not The support frame 2 59 can rotate outside the support frame 1 58, so when the two support frames 3 510 move toward the position close to the support frame 1 58, the four support frames 2 59 rotate on the support frame 1 58 to lift up the support frame 1 58 and the moving plate 1 57 fixedly connected to the support frame 1 58. Since the outer wall of the moving plate 1 57 is fitted with the inner wall of the separation box 53 and is limited and cannot rotate, the moving plate 1 57 is stably moved upward horizontally under the support of the support assembly, and the support frame 4 511 with the other end of the outer side of one of the support frames 3 510 is rotated to the other end. Two telescopic rods 1 512 are fixedly connected between the support frame 4 511 rotatably sleeved at the other end of the outer side of the support frame 3 510. The piston ends of the two telescopic rods 1 512 are respectively fixedly connected to the two support frames 4 511. The telescopic rod 1 512 that can be retracted limits the support frame 4 511 fixed thereto, so that the support frame 4 511 and the support frame 3 510 rotatably connected inside the support frame 4 511 can move stably. With the cooperation of the double-axis hydraulic cylinder 513 and the two telescopic rods 1 512, the support assembly stably controls the moving plate 1 57 to move up and down.

[0042] After the support assembly stops working, a plurality of spring telescopic rods 55 are fixedly installed on the top of the moving plate 57 and stop moving, and a plurality of circular grooves 54 opened on the outside of the separation box 53 correspond to the plurality of spring telescopic rods 55 one by one, so the top of the spring telescopic rod 55 passes through the circular groove 54 and extends to the top of the separation box 53. At this time, a circular pad 56 fixedly connected to the top of the spring telescopic rod 55 is arranged at the bottom of the plate, and the plurality of circular pads 56 support the bottom of the plate. The plurality of circular pads 56 support the finished product cut by the laser cutting equipment 3, so as to reduce the displacement and tilt of the finished product under the action of gravity when the connection area between the finished product and the plate is small in the later stage of cutting, and avoid the finished product cutting process The displacement causes the finished product to be unable to fall or the incision to be irregular; and the spring telescopic rod 55 can be telescoped. When the supporting base plate 44 at the bottom of the conveyor belt 45 moves to the top of the separation box 53, the supporting base plate 44 is located on the upward trajectory of part of the circular pad 56. After the circular pad 56 contacts the supporting base plate 44, the spring telescopic rod 55 contracts during the continued upward movement of the moving plate 57. The setting of the supporting base plate 44 and multiple spring telescopic rods 55 ensures that when the finished product cut by the laser cutting equipment 3 remains in place, the work of the support structure 5 and the conveying structure 4 will not produce adverse mutual interference, thereby ensuring the coordination efficiency of the conveying structure 4 and the support structure 5.

[0043] After the plate cutting is completed, the double-axis hydraulic cylinder 513 is controlled to work and extend. Under the action of the supporting assembly, the moving plate 57 moves downward, and the finished product moves downward with the circular pad 56. Since the top of the separation box 53 is high in the middle and low on both sides, the circular pad 56 in the middle enters the separation box 53 first, and the circular pads 56 on both sides enter the separation box 53 last. The bottom of the circular pad 56 is fixedly connected with a vertical pipe 529. The outer diameter of the circular pad 56 is the same as that of the vertical pipe 529. An annular groove 528 is formed on the outer shell of the spring telescopic rod 55. The bottom end of the vertical pipe 529 is inserted into the annular groove 528. The vertical pipe 529 fills the space between the circular pad 56 and the spring telescopic rod 55. Even if the finished product that falls on the top of the separation box 53 first slides on the inclined surface of the separation box 53, the finished product cannot affect the process of the remaining circular pads 56 entering the separation box 53.

[0044] Finally, multiple circular pads 56 enter the separation box 53, and the finished products finally cut fall to the top of the separation box 53, and fall into the two material receiving boxes 52 set on both sides of the separation box 53 under the action of the inclined surface at the top of the separation box 53. Since the material receiving boxes 52 are in an interference fit state with the separation box 53 and the collection box 51, the material receiving boxes 52 are pulled out of the collection box 51 by pulling them hard, thereby completing the collection of the finished products.

[0045] In addition, such as Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, one side of two support frames 4 511 rotatably sleeved outside one support frame 3 510 is fixedly connected with a moving plate 3 515, a moving plate 2 514 is fixedly connected between the two moving plates 3 515, the moving plate 2 514 moves along with the support frame 4 511, and the moving plate 3 515 in the transmission assembly is arranged on the moving path of one side of the moving plate 2 514, a telescopic liquid storage part 516 and two spring-type telescopic rods 2 517 are fixedly connected between the moving plate 3 515 and the inner wall of the separation box 53, and liquid medium is stored inside the telescopic liquid storage part 516;

[0046] When the double-axis hydraulic cylinder 513 is extended and the moving plate 1 57 is moved downward, the moving plate 2 514 moves a certain distance. At this time, the multiple circular pads 56 located at the top middle position of the separation box 53 have entered the separation box 53. The moving plate 2 514 subsequently moves and contacts the moving plate 3 515 to apply force to the moving plate 3 515. Since the moving plate 3 515 is fixedly connected with two spring-type telescopic rods 2 517 that can be extended and retracted, one end of the two spring-type telescopic rods 2 517 extends to the outside of the collection box 51 and is connected to the separation box 53 and the collection box 5. 1 is fixedly connected, so under the support and limit of the two spring-type telescopic rods 2 517, the moving plate 3 515 moves horizontally, so the moving plate 3 515 pushed by the moving plate 2 514 moves to squeeze the telescopic liquid storage member 516, and the telescopic liquid storage member 516 contracts. The medium inside the telescopic liquid storage member 516 flows out through the guide pipe 1 518 set at one end of the telescopic liquid storage member 516 away from the moving plate 2 514, and the liquid medium enters the inside of the diversion box 519 fixedly connected at one end of the guide pipe 1 518;

[0047] There are two guide pipes 2 523 fixedly connected at the top of the diversion box 519, and the two guide pipes 2 523 are fixedly connected with hydraulic telescopic rods 520, and the piston ends of the hydraulic telescopic rods 520 are fixedly connected with support frames 521, and the two support frames 521 are fixedly inserted with telescopic rods 2 522. Since the piston ends of the two hydraulic telescopic rods 520 are arranged on the left and the right, after the medium inside the diversion box 519 is diverted through the two guide pipes 2 523 and enters the two hydraulic telescopic rods 520, the two hydraulic telescopic rods 520 extend, and the two telescopic rods 2 522 move away from each other. The tops of the two telescopic rods 2 522 are respectively fixedly connected with two push plates 524, and the two push plates 524 are respectively arranged on the inclined surfaces on both sides of the top of the separation box 53, and the two push plates 524 respectively pass through one side of the collection box 51 to open two guide grooves 527, and the push plates 524 can only be tilted and displaced under the action of the inclined guide grooves 527;

[0048] The movement of the telescopic rod 2 522 will drive the fixed push plate 524, and the telescopic rod 2 522 that can be extended can meet the need of the push plate 524 to tilt and move. As the dual-axis hydraulic cylinder 513 continues to extend, the moving plate 1 57 continues to move downward, the moving plate 2 514 continues to move, and the two hydraulic telescopic rods 520 continue to extend. The two push plates 524 tilt downward on the two inclined surfaces at the top of the separation box 53, and the push plates 524 push the finished products on the separation box 53 to move into the receiving box 52. The movement speed of the push plate 524 and the downward movement speed of the moving plate 1 57 reach a dynamic balance, and the moving plate 1 57 drives the circular pad 56 to move down first into the separation box 53 to make room for the movement of the push plate 524 and the finished product pushed by the push plate 524. Finally, the two top surfaces of the separation box 53 The partially circular pad 56 that finally enters the separation box 53 on the side enters the separation box 53 for a period of time, and the push plate 524 moves to the edge of the top inclined surface of the separation box 53. At this time, all the finished products laser-cut from the plates transported by the conveying structure 4 by the laser cutting equipment 3 are concentrated in the receiving box 52, and the finished products that fall from the plates supported and conveyed by the conveying structure 4 can be quickly collected in the receiving box 52, which is convenient for collecting finished products when processing a large number of finished products at one time, and reduces subsequent labor costs. Under the condition that the support structure 5 does not affect the normal operation of the conveying structure 4, the support structure 5 cooperates with the conveying structure 4 to provide a conveying system with conveying, finished product anti-bias support, and automatic collection of multiple finished products for the laser cutting equipment 3 to process the plates, thereby ensuring the processing quality.

[0049] When the dual-axis hydraulic cylinder 513 contracts, the moving plate 2 514 moves to reset, the rebounding spring-type telescopic rod 2 517 pushes the moving plate 3 515 to move, the telescopic liquid storage member 516 extends to draw back the medium inside the hydraulic telescopic rod 520, the hydraulic telescopic rod 520 contracts, and the push plate 524 resets.

[0050] In addition, such as Fig.12 As shown, drainage grooves 530 are provided on one side of the collecting box 51 and one side of the separating box 53.
