Description

Technical Field

[0001] This application relates to the field of laser cutting, and more particularly to an automatic unloading fixture and a laser cutting device. Background Technology

[0002] Currently, lasers are used to cut workpieces, and the waste generated during cutting usually falls directly downwards to a waste collection point. However, due to gravity, the waste tears at the point of contact upon falling, resulting in tiny burrs at the cut endpoint and poor contour at the processing location, leading to low processing accuracy of the workpiece. Utility Model Content

[0003] To address the issue of minute burrs forming at the cutting endpoint during waste material discharge, this application provides an automatic unloading fixture and laser cutting device to improve the processing accuracy of the workpiece.

[0004] This application provides an automatic unloading fixture for collecting waste material generated after workpiece cutting. The automatic unloading fixture includes a housing, a support assembly, and an air blowing assembly. A receiving cavity is formed within the housing. At least a portion of the support assembly can be accommodated within the receiving cavity, supporting the area of ​​the workpiece to be cut, which forms the waste material after cutting. The support assembly is movable along a first direction to guide the waste material into the receiving cavity. The air blowing assembly is located along the movement path of the support assembly and blows the waste material supported by the support assembly into the receiving cavity.

[0005] Understandably, the support assembly supports the area of ​​the workpiece to be cut, and also supports the waste material generated after cutting, preventing it from falling directly into the receiving cavity due to gravity, and also preventing it from tearing the connecting points due to gravity, thus avoiding the formation of tiny burrs at the end of the cut. Using the support assembly to guide the waste material into the receiving cavity improves the machining accuracy of the workpiece.

[0006] In one embodiment, the support assembly includes a support member and a driving member, the driving member being capable of driving the support member to move along the first direction.

[0007] In one embodiment, the blowing assembly includes an air inlet structure and an air blowing element, the air blowing end of the air blowing element being disposed toward the support assembly, and the air inlet structure being used to deliver gas to the air blowing element.

[0014] Another embodiment of the present application provides a laser cutting device, the laser cutting device comprises the automatic material falling jig and a laser cutting assembly, and the laser cutting assembly is used for cutting the waste area of the workpiece.

[0015] It can be understood that the laser cutting device provided with the automatic material falling jig can support the waste through the supporting assembly after the waste is generated by the laser assembly during the processing of the workpiece to be processed, so that the waste cannot directly fall due to gravity to cause a small burr at the cutting end and affect the processing precision.

[0027] This application provides an automatic unloading fixture 100, such as... Figures 1 to 3As shown, an automatic unloading fixture 100 for collecting waste generated after cutting a workpiece (not shown) includes a housing 1, a support assembly 2, and an air blowing assembly 3. The housing 1 has a receiving cavity 10. At least part of the support assembly 2 can be housed within the receiving cavity 10, supporting the area of ​​the workpiece to be cut, which forms waste after cutting. The support assembly 2 is movable along a first direction Z, used to carry the waste into the receiving cavity 10. The air blowing assembly 3 is located on the moving path of the support assembly 2, used to blow the waste supported by the support assembly 2 into the receiving cavity 10.

[0028] For ease of reading, this application introduces a first direction Z, a second direction Y, and a third direction X to describe the embodiments of this application. The first direction Z, the second direction Y, and the third direction X can be three non-parallel straight lines in space; further, the first direction Z, the second direction Y, and the third direction X can be three mutually perpendicular directions in a three-dimensional coordinate system (a three-dimensional Cartesian coordinate system). In subsequent embodiments, the first direction Z is described as the Z-axis direction of the three-dimensional coordinate system, the second direction Y is the Y-axis direction of the three-dimensional coordinate system, and the third direction X is the X-axis direction of the three-dimensional coordinate system.

[0029] In this embodiment, the size of the support surface on the support assembly 2 supporting the area to be cut of the workpiece can be set according to the size of the waste material, so that most of the waste material can be supported by the support surface, avoiding the tearing of the connecting points of the waste material due to gravity due to the unsupported part of the waste material. The size of the support surface can be slightly smaller than the size of the waste material, so that the part of the waste material that does not contact the support surface can subsequently abut against the limiting member 33. At the same time, after the cutting is completed, the waste material can move with the support assembly 2 into the receiving cavity 10 for collection. After the air blowing assembly 3 blows air onto it to blow the waste material off the support assembly 2, the support assembly 2 moves again along the first direction Z towards the area to be cut of the workpiece to support the area to be cut of the next workpiece.

[0030] Understandably, the support component 2 can support the area of ​​the workpiece to be cut, and also support the waste material generated after cutting the area, so that the waste material will not fall directly into the receiving cavity 10 due to gravity, nor will it tear the connecting points due to gravity, thus preventing the formation of tiny burrs at the end point of the cut. Using the support component 2 to guide the waste material into the receiving cavity 10 can improve the processing accuracy of the workpiece.

[0031] In one embodiment, the support component 2 includes a support member 21 and a drive member 22, the drive member 22 being capable of driving the support member 21 to move along a first direction Z.

[0032] In this embodiment, the driving component 22 can be a cylinder, or other driving device capable of driving the support component 21 to move along the first direction Z, as long as it can drive the support component 21 to move; no further restrictions are imposed here. The support component 21 is connected to the driving component 22 so that the driving component 22 drives the support component 21 to move. The supporting surface of the support component 21 is slightly smaller than the area of ​​the waste material so that the portion of the waste material not supported by the support component 21 can abut against the limiting component 33. At the same time, the supporting surface of the support component 21 should not be too smaller than the area of ​​the waste material to avoid the support component 21 failing to provide good support for the waste material, causing the waste material to tear at the connection point due to gravity.

[0033] Understandably, the support member 21 can move along the first direction Z with the drive member 22, thereby moving the waste placed on the support member 21 so that it can enter the receiving cavity 10 and be blown off by the air blowing assembly 3, thus completing the collection of waste.

[0034] In one embodiment, the air blowing assembly 3 includes an air inlet structure 31 and an air blowing element 32, with the air blowing end of the air blowing element 32 facing the support assembly 2, and the air inlet structure 31 used to deliver gas to the air blowing element 32.

[0035] In this embodiment, the air intake structure 31 may include an air intake pipe and a pump capable of delivering gas to the air intake pipe. The air intake pipe may also be connected to the receiving cavity 10 so that the delivered gas enters the receiving cavity 10. The blowing element 32 is also connected to the receiving cavity 10 so that the gas blown in through the air intake structure 31 can enter the blowing element 32 and blow air towards the support assembly 2 through the blowing end of the blowing element 32, so that when the waste is supported by the support assembly 2, it can be blown off by the blowing element 32.

[0036] It is understandable that, by setting the air intake structure 31 and the air blowing component 32 so that when the waste is supported by the support component 2, the waste can be blown off the support component 2 by the air blowing component 3.

[0037] In one embodiment, the air blowing assembly 3 further includes a limiting member 33 located along the first direction Z on the movement path of the waste material, for supporting the waste material.

[0038] In this embodiment, the limiting member 33 can be a block-shaped object, which can be fixedly connected to the inner wall of the housing 1 and located on the movement path of the waste. When the waste moves along the first direction Z with the support member 21, the waste moves to abut against the limiting member 33 and then stops moving, so that the subsequent air blowing assembly 3 can blow air onto the waste. A sensor can be provided on the limiting member 33. When the waste abuts against the limiting member 33, the sensor senses and activates the air blowing assembly 3 to blow the waste off.

[0039] Understandably, the setting of the limiting member 33 makes the movement of the waste material along the first direction Z controllable, and can better cooperate with the air blowing component 3 so that the subsequent waste material is no longer supported by the support component 2.

[0040] In other embodiments, since the waste material is slightly larger than the support surface of the support member 21, the limiting member 33 can be configured to correspond to the shape of the support member 21 so that the portion of the waste material not supported by the support member 21 can contact the limiting member 33 and be limited.

[0041] In one embodiment, such as Figure 3 and Figure 4 As shown, the limiting member 33 has an airflow channel 330, which is connected to the blowing end of the blowing member 32. Airflow can enter from the air inlet end of the airflow channel 330, and waste can block the air outlet end of the airflow channel 330.

[0042] In this embodiment, when the waste material blocks the outlet end of the airflow channel 330, the airflow channel 330 connected by the air blowing end of the air blowing element 32 will have gas blown by the air blowing element 32, which will be discharged to the outlet end. At this time, since the waste material blocks the outlet end of the airflow channel 330, the airflow will blow the waste material to make the airflow discharge from the outlet end, and at the same time the waste material will also be blown off the support 21.

[0043] In one embodiment, the airflow channels 330 are provided with multiple channels.

[0044] Understandably, the multiple airflow channels 330 ensure that the outflowing airflow can blow the waste off the support 21 so that the support assembly 2 can continue to be used to support the cutting area of ​​the next workpiece to be processed.

[0045] In one embodiment, the automatic feeding fixture 100 further includes a collecting member 4, which has a collecting cavity 40 that communicates with the receiving cavity 10, and waste materials can be collected in the collecting cavity 40. The collecting member 4 is movable along the second direction Y.

[0046] In this embodiment, the waste is blown off the support member 21 and falls into the collection chamber 40. The collection member 4 can be a drawer, which can move along the second direction Y. When the waste accumulates to a certain amount, the operator pulls the collection member 4 along the second direction Y so that the collection member 4 is partially separated from the box 1, so that the waste contained in the collection chamber 40 can be poured out for continued use.

[0047] In other embodiments, the collection component 4 is sealed with a sealing ring and can be magnetically attached to the housing 1 to prevent air leakage, thereby making the blowing assembly 3 more effective when blowing air.

[0048] In one embodiment, the automatic unloading fixture 100 further includes a connecting component 5, which is connected to the housing 1. The connecting component 5 has a connecting cavity 50, which communicates with the receiving cavity 10.

[0049] In this embodiment, the connecting assembly 5 includes a carrier plate 51, a positioning plate 52, and a base plate 53. The carrier plate 51 and the base plate 53 are connected by the positioning plate 52. The base plate 53 is connected to the top of the housing 1. The carrier plates 51 are spaced apart on the side of the base plate 53 away from the housing 1. The workpiece to be processed is placed on the carrier plate 51. Along the first direction Z, the connecting cavity 50 extends from the top surface of the carrier plate 51 and passes through the carrier plate 51, the positioning plate 52, and the base plate 53 in sequence. The carrier plate 51 can be set according to the shape of the workpiece to be processed, and the workpiece to be processed can be fitted onto the carrier plate 51. In actual use, the connecting assembly 5 is blackened to prevent reflection, thereby improving the sampling accuracy during laser cutting and making the cutting more accurate.

[0050] Understandably, the connection component 5 is designed so that the workpiece to be processed can be placed on the connection component 5 in a better way, so that the waste generated after the workpiece to be processed in the processing area can fall into the receiving cavity 10 of the box 1.

[0051] Another embodiment of this application provides a laser cutting apparatus 200, such as... Figure 5 and Figure 6 As shown, the laser cutting device 200 includes the automatic unloading fixture 100 and a laser cutting assembly (not shown in the figure), which is used to cut the area of ​​the workpiece to be cut into scrap.

[0052] In this embodiment, the workpiece to be processed is mounted on the automatic unloading fixture 100, and then the workpiece to be processed can be laser-cut by the laser cutting component. The waste generated can be transported to the collection chamber 40 by the automatic unloading fixture 100.

[0053] Understandably, the laser cutting device 200 equipped with the aforementioned automatic unloading fixture 100 can support the waste material generated during the laser assembly's processing of the workpiece via the support component 2. This prevents the waste material from falling directly due to gravity, which could cause minute burrs at the cutting endpoint and result in poor processing accuracy. This improves the processing accuracy of the workpiece cut by the laser cutting device 200.

[0054] In one embodiment, the laser cutting apparatus 200 further includes a clamping assembly 201 for clamping the workpiece.

[0055] In this embodiment, a clamping assembly 201 is respectively provided on both sides of the housing 1 along the third direction X to clamp the workpiece to be processed on both sides of the connecting assembly 5 in the third direction X, so that the workpiece will not move arbitrarily during processing and the processing is reliable. The clamping assembly 201 may be composed of a cylinder and a pressure block. The pressure block is driven by the cylinder to move along the first direction Z to clamp the workpiece.

[0056] The specific embodiments of this application have been described above with reference to the accompanying drawings. However, those skilled in the art will understand that various changes and substitutions can be made to the specific embodiments of this application without departing from the spirit and scope of this application. All such changes and substitutions fall within the scope defined by this application.
