DETAILED DESCRIPTION

[0021] It should be noted that the embodiments in the present application and the technical features in the embodiments can be combined with each other without conflict, and the detailed description in the specific embodiments should be understood as the explanation and description of the present application, and should not be regarded as improper limitation on the present application.

[0022] The orientation terms in the description of the present application are only for the convenience of describing the present application and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0023] In the related art, in many automated factories, the material to be processed needs to be carried to the machine tool slide of the laser cutting machine by AGV (Automated Guided Vehicle). However, due to the relatively large weight of the material to be processed, the AGV lacks the function of lifting the material by a large amplitude, and when transporting a material with a large width, it cannot directly pass through the auxiliary structure in the laser cutting machine, such as a pneumatic cylinder. Even if the AGV can lift the material by a certain amplitude, it may collide with the auxiliary structure of the cutting machine when placing the material. In general, the material can be placed on the processing platform from the side, but for a laser cutting machine arranged in a narrow space, it is not possible to complete the feeding work from the side.

[0024] Therefore, the embodiments of the present application expect to provide a feeder, with reference to Figure 1 and Figure 2 The feeder 10 includes a bracket 1, a support platform 2, a lifting mechanism 3, and a transverse movement mechanism 4. The bracket 1 is arranged on the support platform 2 and is used to support the material; the lifting mechanism 3 is connected with the support platform 2 and is used to lift the support platform 2; the transverse movement mechanism 4 is arranged on the support platform 2 and is drivingly connected with the bracket 1, so that the bracket 1 can move along the feeding direction.

[0025] Specifically, with reference to Figure 1 and Figure 5, the material 7 is first placed on the bracket 1, and before the machine tool slide 6 is moved below the material 7, the material 7 is lifted by the lifting mechanism 3 to avoid the moving track of the machine tool slide 6 from the height. Then the material 7 is horizontally moved by the transverse mechanism 4 to avoid the corresponding structure on the machine tool slide 6, such as the cylinder assembly 61, etc., to prevent collision when the material 7 is placed down. Finally, the material 7 is placed on the machine tool slide 6.

[0026] In this way, the material 7 is moved in the height direction and the feeding direction by the lifting mechanism 3 and the transverse mechanism 4, so that the material 7 avoids the moving track of the machine tool slide 6 and its attached structure, avoids interference and collision, and realizes the feeding process in a narrow space.

[0027] Further, the lifting mechanism 3 can be a hydraulic lifter, or a scissor lifting structure or a screw rod lifting structure. The bracket 1 can include an upper structure and a lower structure, the upper structure is provided with a wooden strip or a rubber strip, etc., and the lower structure is provided with a metal support, so as to realize the lightweight of the structure on the one hand, and also to reduce the wear and tear between the material 7 and the feeding machine on the other hand.

[0028] Further, the bracket 1 can also include longitudinal supports parallel in the feeding direction and a plurality of transverse supports perpendicular to the longitudinal supports. In this way, the support area of the bracket 1 is increased, so that the placement and lifting of the material 7 are more stable.

[0029] In some embodiments, referring to Figure 1 The lifting mechanism 3 includes a lifting assembly 31 and a guide assembly 32. The lifting assembly 31 includes a lifting rod 311 connected with the support platform 2 and a lifting drive 312 drivingly connected with the lifting rod 311; the guide assembly 32 includes a guide rod 321 and a guide cylinder 322 in a sleeve connection, one of the guide rod 321 and the guide cylinder 322 is connected with the support platform 2, and the other of the guide rod 321 and the guide cylinder 322 is connected with the foundation or the fixed seat. When the lifting rod 311 moves up and down, the guide rod 321 can slide along the guide cylinder 322.

[0030] Specifically, the lifting drive 312 can include a pneumatic drive, a hydraulic drive or a motor drive to provide a power source for the lifting movement of the support platform 2. The guide assembly 32 is arranged perpendicular to the ground, the guide rod 321 can be connected with the support platform 2, and the guide cylinder 322 is fixed on the foundation or the fixed seat.

[0031] In this way, on the basis of the lifting assembly 31 for realizing the lifting of the support platform 2, the guide assembly 32 perpendicular to the ground provides a guide function during the lifting of the bracket 1 and the support platform 2.

[0032] Further, referring to Figure 3The lifting rod 311 and the guide rod 321 can be straight rods, and a reserved hole 333 is preset at the position of the lifting rod 311 and the guide rod 321 on the ground. When the bracket 1 is in the low position, the lower section of the lifting rod 311 and the guide rod 321 is accommodated in the reserved hole 333.

[0033] In some embodiments, the lifting mechanism 3 further comprises a fixing base 33. The lifting driving member 312, and the other of the guide rod 321 and the guide cylinder 322 are arranged on the fixing base 33.

[0034] Specifically, the fixing base 33 is fixed on the ground, so that the structural stability of the feeder 10 as a whole is enhanced.

[0035] Further, as shown in Figure 3 and Figure 4 , the fixing base 33 can comprise an above-ground structure and an underground structure. The above-ground structure comprises a mounting base 331, and the mounting base 331 is provided with a flange connecting port or a screw hole. The lifting assembly 31 or the guide assembly 32 can be fixed on the mounting base 331 by a flange connecting member or a bolt member. The underground structure comprises a containing cabin 332 containing the lifting driving member 312, a reserved hole 333 containing the lifting rod 311, and a reserved hole 333 containing the guide rod 321. The containing cabin 332 and the reserved hole 333 can also be directly excavated in the foundation.

[0036] In this way, when the bracket 1 is in the low position, the height of the top surface of the bracket 1 will not be higher than the height of the machine tool slide 6, and the material can be directly placed on the machine tool slide 6, thereby reducing the feeding difficulty. For the construction convenience of the reserved hole 333, as shown in Figure 3 , the reserved holes 333 of the lifting rod 311 and the guide rod 321 can be integrated.

[0037] In some embodiments, the number of the lifting mechanism 3 is two, the lifting assemblies 31 of the two lifting mechanisms 3 constitute a screw rod lifting machine, the lifting rods 311 are lifting screw rods, the lifting screw rods are arranged at intervals, and the lifting driving members 312 of the two lifting mechanisms 3 are shared.

[0038] Specifically, as shown in Figure 1 and Figure 2The lifting driving member 312 comprises a driving motor 3122 and a steering gear 3121, the steering gear 3121 comprises an input shaft and two output shafts, the input shaft is engaged with the two output shafts respectively, the input shaft is perpendicular to the two output shafts respectively, and the steering gear 3121 has a “T” shape structure. The output shaft of the driving motor 3122 is connected with the input shaft of the steering gear 3121. When the driving motor 3122 is started, the input shaft of the steering gear 3121 is driven to rotate, and then the two output shafts are driven to rotate. The lifting assembly 31 further comprises a worm gear reducer 313, the worm gear reducer 313 is internally provided with a worm and a worm wheel (not shown in the figure), the worm is connected with the output shaft of the steering gear 3121, the worm is engaged with the worm wheel, and the worm wheel is internally provided with a threaded structure and is tightly matched with the thread of the lifting rod 311. When the lifting driving member 312 drives the worm to rotate, the worm wheel also rotates, and then the lifting rod 311 is driven to move up and down, and then the lifting of the support platform 2 is realized.

[0039] In this way, one lifting driving member 312 can provide power source for two lifting rods 311, the overall cost of the feeder 10 is saved, and the occupied space is smaller. Meanwhile, the combination of the two lifting rods 311 of the lifting assembly 31 can significantly improve the carrying capacity of the feeder 10. Meanwhile, through the arrangement of the steering gear 3121, the rotating speeds of the two output shafts can be controlled, and then the two lifting rods 311 can keep the same height during the lifting process.

[0040] Further, the gap between the internal thread of the worm wheel in the worm gear reducer 313 and the thread of the lifting rod 311 can be embedded with a ball to reduce the wear between the threads.

[0041] In some embodiments, referring to Figure 1 and Figure 2 shown, the transverse moving mechanism 4 comprises a transverse moving guide rail 41 and a transverse moving driving member 42. The transverse moving guide rail 41 is arranged on the support platform 2, and the bracket 1 is slidingly arranged on the transverse moving guide rail 41; the transverse moving driving member 42 is drivingly connected with the bracket 1, so that the bracket 1 can slide on the transverse moving guide rail 41 in the feeding direction.

[0042] Specifically, the transverse moving guide rail 41 can be a straight rail connected with the support platform 2. In another embodiment, the transverse moving guide rail 41 can also be a guide groove parallel to the feeding direction, and a sliding block which is movably connected with the guide groove can be arranged on the bracket 1.

[0043] In this way, through the arrangement of the transverse moving guide rail 41, the movement of the bracket 1 can be guided to avoid deviating from the direction, and the friction between the bracket 1 and the support platform 2 can also be reduced. The transverse moving driving member 42 can be a driving motor or a pneumatic piston structure to provide power source for the movement of the bracket 1.

[0044] In some embodiments, referring to Figure 1 andFigure 2 As shown, the transverse mechanism 4 further includes a transverse nut 43 and a transverse screw 44. The transverse nut 43 is provided on the bracket 1; the transverse screw 44 is provided on the support platform 2, the transverse nut 43 is in driving connection with the transverse screw 44, and the transverse driving member 42 is in driving connection with the transverse screw 44.

[0045] Thus, when the traverse screw 44 is rotated, the traverse nut 43 moves along the length of the traverse screw 44, thereby driving the bracket 1 to move along the feeding direction. The traverse mechanism 4 has a compact and simple structure, and the traverse screw 44 is not easy to bend, which can reduce the deviation of the moving direction of the bracket 1.

[0046] Furthermore, a ball bearing may be embedded between the transverse screw rod 44 and the transverse nut 43 , thereby further reducing wear between the transverse screw rod 44 and the transverse nut 43 .

[0047] In some embodiments, referring to Figure 2 As shown, the transverse movement mechanism 4 further includes an in-position detection component 45 , which is disposed on the support platform 2 and is used to detect the starting limit position and the end limit position of the transverse movement nut 43 along the feeding direction.

[0048] Specifically, the in-position detection assembly 45 can be a photoelectric detection assembly, which is installed on the support platform 2 near the two ends of the transverse guide rail 41. It constantly detects the distance between the transverse nut 43 and the in-position detection assembly 45. When the distance reaches a limit, the in-position detection assembly 45 can send a stop signal to stop the transverse drive member 42. Similarly, the in-position detection assembly 45 can also include detection components such as a proximity switch, a piezoelectric sensor, or a magnetoelectric sensor.

[0049] In this way, the in-position detection component 45 can control the working state of the transverse driving member 42. When the movement of the transverse nut 43 is about to exceed the limited range, the movement of the transverse driving member is stopped to protect the working safety of the transverse mechanism.

[0050] Another aspect of the present application provides a laser cutting machine, comprising any one of the feeders 10 described above. The number of the feeders 10 can be one, two, or more.

[0051] In some embodiments, referring to Figure 2 and Figure 5 As shown, there are two feeders, and the laser cutting machine also includes two groups of machine tool slides 6 and discharge platforms arranged at intervals. Each group of discharge platforms is arranged on the machine tool slide 6 and can move along the feeding direction on the machine tool slide 6. The two feeders 10 are arranged on the inner sides of the two machine tool slides 6 at intervals.

[0052] In this way, the two feeders 10 can provide greater load-bearing capacity and provide multiple force points, making the feeding process more stable. And being arranged inside can also reduce the area occupied by the laser cutting machine in the workshop.

[0053] Furthermore, each feeder 10 can be provided with two lifting rods 311, for a total of four lifting rods 311. These four lifting rods 311 are linked by components such as couplings and steering gears, and share a lifting drive member 312 as a power source, so that the occupied space is smaller and the lifting of the two brackets 1 is more stable and consistent.

[0054] On the other hand, an embodiment of the present application provides a laser cutting production line, including: an AGV trolley for transporting materials to be processed 7; and any one of the above-mentioned laser cutting machines, the AGV trolley being capable of transporting the materials to be processed 7 to a feeder 10.

[0055] Specifically, the AGV can also have a certain lifting capacity. In this way, when the AGV is carrying the material 7, it can move in a low posture, lowering the overall center of gravity. When it is transported to the feeder 10 of the laser cutting machine, the material 7 is lifted to a certain height and placed on the feeder 10, completing the initial feeding process.

[0056] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0057] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
