Description

Technical Field

[0001] The utility model relates to the field of laser processing equipment, in particular to laser processing equipment with a feeding device. Background Art

[0002] Laser processing can be roughly divided into two categories: laser thermal processing and photochemical reaction processing according to the mechanism of interaction between the laser beam and the material. Laser thermal processing refers to the use of the thermal effect generated by the laser beam projected onto the surface of the material to complete the processing process, including laser welding, laser engraving and cutting, surface modification, laser marking, laser drilling and micromachining, etc. Among them, laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporated to form holes. As the beam moves on the material, the holes continuously form a very narrow slit, completing the cutting of the material.

[0003] During the processing of existing laser processing equipment, materials are mostly loaded and unloaded by robots or even manpower. Manpower is difficult to use for industrial mass production and processing. Industrial robots are expensive and can only process materials on the raw material rack at a time. It is difficult to store large amounts of materials for continuous processing, which affects loading and unloading efficiency.

[0004] For example, the utility model patent with publication number CN207431546U discloses a laser processing device with a loading device, including a detection part for detecting the workpiece to be processed, a manipulator for fixing the workpiece to be processed, and a transmission device located at the bottom of the workpiece to be processed; the detection part includes a cross-transmission track and a detector; the cross-transmission track includes a first transmission track perpendicular to the transmission direction of the workpiece to be processed and a second transmission track parallel to the transmission direction of the workpiece to be processed, and the detector is transported to the required position by the first transmission track; the manipulator includes two first manipulators and a second manipulator for fixing the workpiece to be processed, and the distribution direction of the two first manipulators is parallel to the transmission direction of the workpiece to be processed. This laser processing loading device can not only realize the transmission and loading of various steel materials such as plates and pipes, but also realize functions such as fixing and position adjustment of steel materials, and can achieve precise control of processed steel materials, facilitating the processing operation of the laser processor.

[0005] However, since it uses multiple groups of robots to collaborate in the handling and loading and unloading of materials, the cost of multiple robots is relatively high, and the transfer between robots still takes a long time to complete. Utility Model Content

[0015] As a preferred embodiment: a buffer pad is provided on the supporting plate.

[0016] As a preferred embodiment: the side frame is open on both sides along the translation direction of the translation device, and the translation device is installed at the opening on the side away from the main frame to drive the support plate in the side frame to extend into and withdraw from the loading channel.

[0028] The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0029] The following describes the embodiments of the present disclosure through specific examples, and those skilled in the art can easily understand other advantages and effects of the present disclosure from the contents disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all of the embodiments. The present disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0030] Example 1

[0031] like Figure 1 As shown, a laser processing equipment with a loading device includes a processing platform 1 and a laser processing equipment 2 arranged above the processing platform 1. Two vertical deep grooves are opened on the processing platform 1. The length direction of the deep grooves is consistent with the length direction of the processing platform 1, that is, the transportation direction of the plate to be processed on the processing platform 1.

[0032] A synchronous belt structure 11 is installed in the deep groove, serving as a conveying device for transporting the plates to be processed. Two lifting cylinders 12 are installed below one end of the synchronous belt structure 11. The two lifting cylinders 12 operate synchronously and are fixedly mounted on the equipment plate 16 below the work platform 1. The movable ends of the lifting cylinders 12 are fixedly connected to the synchronous belt structure 11. When the plates to be processed need to be transported, the two lifting cylinders 12 simultaneously lift the synchronous belt structure 11 upward and above the upper surface of the processing platform 1. The synchronous belt structure 11 then transports the plates to be processed on the processing platform 1 to the bottom of the laser processing equipment 2. The two lifting cylinders 2 then descend, and the two synchronous belt structures 11 retreat downward into the deep groove to ensure that the plates to be processed are stably placed on the processing platform 1 and prevent accidental damage to the synchronous belt structure 11 during laser processing. Once the processing is completed, the lifting cylinders 2 lift the synchronous belt structure 11 again to transport the next plate to be processed.

[0033] It also includes a main frame 3. In some preferred embodiments, the main frame 3 is fixedly arranged on both sides of the length direction of the processing platform 1. The main frame 3 is preferably a rectangular structure with openings on the top and bottom. The side close to the laser processing equipment 2 is the front side. The front, back, left and right sides are all hollow designs. Except for the front side, the other three sides are provided with a number of vertical vertical panels 31 for limiting the transported plates to be processed. A cross bar 7 is fixed on the front side, and a baffle 8 that can slide up and down is provided under the cross bar 7. The cross bar 7 is internally threaded with a screw 9, and the baffle 8 is threadedly connected to the screw 9. By twisting and rotating the screw 9, the baffle 8 can be driven to slide up and down. A limiting plate 10 is provided on the outside (i.e., the front side) of the baffle 8. The limiting plate 10 is fixedly installed on the main frame 3 to prevent the baffle 8 from sliding out of the main frame 3. The four sides of the main frame 3, front, back, left and right, form a loading channel. The top of the loading channel is open and the bottom is a processing platform 1. The height of the baffle 8 is adjusted to adjust the distance between the bottom of the baffle 8 and the processing platform 1, so as to cope with different heights of stacked plates to be processed. The gap distance is greater than the height of one plate to be processed and less than the height of two plates to be processed, so as to ensure that only one plate to be processed passes through at a time.

[0034] In some preferred embodiments, a wheel frame 6 is provided at the bottom of the loading channel, which is tilted downward toward the laser processing equipment 2. Several parallel rubber rollers 61 are provided on the wheel frame 6. The rubber rollers 61 can rotate freely or be driven by an external motor to guide the plate to be processed. In this scheme, the distance between the baffle 8 and the wheel frame 6 is also adjusted to ensure that a single plate to be processed passes through.

[0035] A lifting device is provided on the rear side of the main frame 3. In this embodiment, the lifting device is a lifting electric cylinder 14. The movable end of the lifting electric cylinder 14 is fixedly connected to the side frame 4 to drive the side frame 4 to perform reciprocating lifting motion.

[0036] The side frame 4 is a rectangular parallelepiped as a whole, with both front and rear sides open. A translation device is provided on the rear side of the side frame 4. In this embodiment, the translation device is a translation electric cylinder 15. The movable end of the translation electric cylinder 15 is connected to the corner frame 13, and the horizontal support plate 5 is fixedly connected to the corner frame 13.

[0037] In some embodiments, the rear side of the main frame 3 is not provided with a vertical panel 31, and the entire frame is hollowed out. In this case, the support plate 5 is set as an ordinary horizontal plate and can be extended into the feeding channel.

[0038] Since in this embodiment, a parallel vertical panel 31 is set on the rear side of the main frame 3 to limit the plate to be processed, the support plate 5 is arranged into several divided panels 51 with gaps. The several divided panels 51 are just staggered with the vertical panels 31 on the rear side of the main frame 3, and can enter the loading channel from the gaps between adjacent vertical panels 31 to support the plate to be processed.

[0039] In some preferred embodiments, a buffer pad 52 is provided on each split plate 51 to prevent the plate to be processed from colliding with the plate to be processed and damaging the plate to be processed when loading the plate onto the support plate 5 .

[0040] When the present invention is working, first, a stack of plates to be processed is transported to the top of the main frame 3 through the equipment therein. At this time, the lifting electric cylinder 14 on the top of the rear side of the main frame 3 contracts to lift the side frame 4 to the highest position, and the translation electric cylinder 15 on the rear side of the side frame 4 drives the pallet 5 to extend into the loading channel. After the equipment places the plates to be processed on each sub-plate 51, the lifting electric cylinder 14 drives the side frame 4 to descend and transports the plates to be processed to the bottom of the loading channel. At this time, the translation electric cylinder 15 contracts, and the pallet 5 is driven out of the loading channel. The plates to be processed are blocked by the vertical panel 31 on the rear side of the main frame, and thus fall on the wheel frame 6 below. The rotation of the rubber roller on the wheel frame 6 drives the plates to be processed to move forward.

[0041] Since the height of the baffle 8 has been set in advance, the plates to be processed stacked above are blocked by the baffle 8 when moving forward, and only the bottom plate to be processed is driven forward by the synchronous belt structure 11 until it reaches the bottom of the laser processing equipment 2, while the plates to be processed stacked above fall down, and the bottom plate to be processed continues to pass through the gap at the bottom of the baffle 8.

[0042] During processing, the lifting cylinder 12 descends, the synchronous belt 11 retracts into the deep groove, and the plate to be processed stops moving on the processing platform 1. When processing is completed, the lifting cylinder 12 returns to its original position and lifts up the synchronous belt 11, continuing to transport the plate to be processed that has passed through the gap at the bottom of the baffle 8 to the bottom of the laser processing equipment 2 for processing.

[0043] The utility model can transport several stacked plates to be processed at one time, and transport them one by one to the bottom of the laser processing equipment 2 for processing after being blocked by the baffle 8, thereby greatly improving the loading efficiency. The utility model has a relatively simple structure, a reasonable design of the loading equipment, saves transportation costs, and is suitable for promotion and use.
