[0023] Please see Figure 1This utility model provides a laser processing apparatus 100, including a processing bed 10, a loading bed 20, and a conveying assembly 30. The loading bed 20 is detachably connected to the processing bed 10. A first mounting portion 11 is provided on the side of the processing bed 10 closest to the loading bed 20, and a second mounting portion 21 is provided on the side of the loading bed 20 closest to the processing bed 10. The conveying assembly 30 includes a chain condition 31 and a support bar 33. The support bar 33 is disposed on the chain condition 31. The chain condition 31 includes a first chain portion 311 and a second chain portion 313. The first chain portion 311 is disposed on the processing bed 10 and detachably connected to the first mounting portion 11, and the second chain portion 313 is disposed on the loading bed 20 and detachably connected to the second mounting portion 21. The first chain portion 311 and the second chain portion 313 are detachably connected.

[0024] In this embodiment of the invention, the conveying assembly 30, after installation and debugging, can be disassembled. Specifically, the first chain section 311 and the second chain section 313 are disassembled, the first chain section 311 is connected to the first mounting section 11, and the second chain section 313 is connected to the second mounting section 21. The processing bed 10 and the unloading bed 20 are then separated, thereby enabling separate transportation of the processing bed 10 and the unloading bed 20. After transportation is completed, the connection between the first chain section 311 and the first mounting section 11 is released, and the connection between the second chain section 313 and the second mounting section 21 is released, allowing the first chain section 311 and the second chain section 313 to be reconnected. The unloading bed 20 is then reconnected to the processing bed 10. This ensures that the transmission between the processing bed 10 and the unloading bed 20 is not interrupted due to the discontinuity of the conveying assembly 30, and also reduces the debugging steps required after transportation, facilitating the transportation of the laser processing device 100.

[0025] Specifically, the machining bed 10 is used to support the workpiece for machining. It is understood that, in one embodiment, the machining bed 10 is used to support the workpiece for laser processing.

[0026] The unloading bed 20 is used to carry workpieces for unloading and sorting. Understandably, there are many ways in which the unloading bed 20 and the machining bed 10 can be detachably connected. In one embodiment, the unloading bed 20 and the machining bed 10 are detachably connected by bolts. In another embodiment, the machining bed 10 has a receiving groove on the side near the unloading bed 20, and the unloading bed 20 is housed within the receiving groove, with bolts passing through the receiving groove to connect to the unloading bed 20. In yet another embodiment, the machining bed 10 includes machining support legs, and the unloading bed 20 includes unloading support legs; the machining support legs and the unloading support legs are detachably connected by a connecting strap.

[0027] Understandably, the conveying assembly 30 may include two chain conditions 31. The conveying direction of the conveying assembly 30 is defined as a first direction, and a second direction is perpendicular to the first direction. The two chain conditions 31 may be arranged parallel to each other along the first direction. Along the second direction, the two chain conditions 31 are sequentially spaced on both sides of the machining bed 10 and the unloading bed 20. The two ends of the support bar 33 are respectively connected to the two chain conditions 31, and the support bar 33 is arranged along the second direction. Understandably, the conveying assembly 30 may include multiple support bars 33, all of which are arranged parallel to each other along the second direction, and the multiple support bars 33 are arranged sequentially along the first direction.

[0028] Understandably, chain condition 31 can be a chain connected end to end to achieve cyclic transmission by the transmission component 30. Therefore, when the first chain section 311 and the second chain section 313 are separated, there are two separation positions for the first chain section 311 and the second chain section 313. The two separation positions are arranged sequentially in the vertical direction, that is, the two ends of the first chain section 311 are separated from the two ends of the second chain section 313. Therefore, the machining bed 10 can be provided with two first mounting parts 11, which are arranged sequentially in the vertical direction to limit the two ends of the first chain section 311. The unloading bed 20 can be provided with two second mounting parts 21, which are arranged sequentially in the vertical direction to limit the two ends of the second chain section 313.

[0029] Understandably, there are many ways to detachably connect the first chain portion 311 and the first mounting portion 11. The first chain portion 311 can be connected to the first mounting portion 11 by means of bolt connection, snap-fit, plug-in connection, etc. In one embodiment, the first mounting portion 11 includes a first snap-fit ​​protrusion and a first protrusion mounting hole. The first snap-fit ​​protrusion can pass through the first chain portion 311 to limit the first chain portion 311, and the first snap-fit ​​protrusion and the first protrusion mounting hole are interference-fitted.

[0030] Understandably, there are many ways to detachably connect the second chain portion 313 and the second mounting portion 21. The second chain portion 313 can be connected to the second mounting portion 21 by means of bolt connection, snap-fit, plug-in connection, etc. In one embodiment, the second mounting portion 21 includes a second snap-fit ​​protrusion and a second protrusion mounting hole. The second snap-fit ​​protrusion can pass through the second chain portion 313 to limit the second chain portion 313, and the second snap-fit ​​protrusion and the second protrusion mounting hole are interference-fitted.

[0031] Please see Figures 1 to 6 In this embodiment of the utility model, the laser processing device 100 further includes a first bolt member 40, the first mounting part 11 includes a first bolt hole (not shown), the first chain part 311 is provided with a first chain hole 3111, and the first bolt member 40 can pass through the first chain hole 3111 and be threadedly connected to the first bolt hole.

[0032] Thus, the first bolt 40 passes through the first chain hole 3111 and is threadedly connected to the first bolt hole, realizing a detachable connection between the first mounting part 11 and the first chain part 311, resulting in low production and installation costs and simple operation.

[0033] Understandably, the first chain section 311 is usually naturally provided with a first chain hole 3111, so the first chain hole 3111 does not require additional processing steps, and the connection cost is low.

[0034] It is worth noting that the laser processing device 100 may include a plurality of first bolt members 40, and the first mounting part 11 may include a plurality of first bolt holes. The plurality of first bolt holes are arranged sequentially along the extension direction of the first chain part 311, and the first bolt members 40 correspond one-to-one with the first bolt holes. In this way, the first chain part 311 can be limited at multiple points, so that the first chain part 311 is evenly stressed, reducing wear on the first chain part 311 and reducing shaking of the first chain part 311 during transportation.

[0035] Please see Figures 1 to 6 Furthermore, the laser processing device 100 also includes a first gasket 43, which includes a first through hole 431. A first bolt 40 passes through the first through hole 431, and the first gasket 43 abuts against the first chain portion 311.

[0036] In this way, the first washer 43 can evenly apply the force from the first bolt 40 to the first chain portion 311, reducing the probability of the first bolt 40 wearing the first chain portion 311.

[0037] For further details, please refer to Figure 2 and Figure 6 The first gasket 43 is provided with two first through holes 431, which are spaced apart, and the two first bolts 40 are respectively passed through the two first through holes 431.

[0038] Thus, the two first bolts 40 are respectively provided with two first through holes 431, which can limit the first washer 43, reduce the probability of the first washer 43 wobbling relative to the two first bolts 40, further reduce the probability of the first washer 43 wearing the first chain part 311, and ensure a good contact relationship of the first washer 43.

[0039] Please see Figures 1 to 6 In this embodiment of the present invention, the laser processing device 100 further includes a second bolt member 50, the second mounting part 21 includes a second bolt hole (not shown), the second chain part 313 is provided with a second chain hole 3131, and the second bolt member 50 can pass through the second chain hole 3131 and be threadedly connected to the second bolt hole.

[0040] Thus, the second bolt 50 passes through the second chain hole 3131 and is threadedly connected to the second bolt hole, realizing a detachable connection between the second mounting part 21 and the second chain part 313, resulting in low production and installation costs and simple operation.

[0041] Understandably, the second chain section 313 is usually naturally provided with a second chain hole 3131, so the second chain hole 3131 does not require additional processing steps, resulting in lower connection costs.

[0042] It is worth noting that the laser processing device 100 may include multiple second bolt members 50, and the second mounting part 21 may include multiple second bolt holes. The multiple second bolt holes are arranged sequentially along the extension direction of the second chain part 313, and the second bolt members 50 correspond one-to-one with the second bolt holes. In this way, the second chain part 313 can be limited at multiple points, so that the second chain part 313 is evenly stressed, reducing wear on the second chain part 313 and reducing shaking of the second chain part 313 during transportation.

[0043] For further details, please refer to Figures 1 to 6 The laser processing device 100 also includes a second gasket 53, which includes a second through hole 531. The second bolt 50 passes through the second through hole 531 and abuts against the second chain portion 313.

[0044] In this way, the second washer 53 can evenly apply the force from the second bolt 50 to the second chain portion 313, reducing the probability of the second bolt 50 wearing the second chain portion 313.

[0045] For further details, please refer to Figure 2 and Figure 6 The second gasket 53 is provided with two second through holes 531, which are spaced apart, and the two second bolts 50 are respectively passed through the two second through holes 531.

[0046] Thus, the two second bolts 50 are respectively provided with two second through holes 531, which can limit the second washer 53, reduce the probability of the second washer 53 wobbling relative to the two second bolts 50, further reduce the probability of the second washer 53 wearing the second chain part 313, and ensure a good contact relationship between the second washer 53 and the second bolt.

[0047] In this embodiment of the utility model, please refer to Figure 2 and Figure 6 Both the first through hole 431 and the second through hole 531 are oblong holes.

[0048] In this way, production and installation errors can be compensated for, and the relative positional relationship between the first gasket 43, the second gasket 53 and the chain condition 31 can be finely adjusted as needed.

[0049] Understandably, there are many possible orientations for the waist-shaped hole. In one embodiment, the length direction of the waist-shaped hole is set along the extension direction of the chain condition 31. In another embodiment, the length direction of the waist-shaped hole is set perpendicular to the extension direction of the chain condition 31. In yet another embodiment, the length direction of the waist-shaped hole is at an angle to the extension direction of the chain condition 31.

[0050] In this embodiment of the utility model, please refer to Figure 1 , Figure 2 , Figures 7 to 10 The laser processing device 100 also includes a machine tool connector 60, which includes a first connecting plate 61 and a second connecting plate 63. The first connecting plate 61 and the second connecting plate 63 are perpendicular to each other. The first connecting plate 61 is provided with a first connecting through hole 611, and the second connecting plate 63 is provided with a second connecting through hole 631. The arrangement direction of the processing bed 10 and the unloading bed 20 is defined as a first direction. The processing bed 10 is provided with a first connecting surface 13 perpendicular to the first direction. The first connecting surface 13 is provided with a first mating hole 131. Along the first direction, the projection of the unloading bed 20 is spaced apart from the first mating hole 131. The first connecting through hole 611 is aligned with the first mating hole 131 so that the first connecting surface 13 is bolted to the first connecting plate 61. The unloading bed 20 is provided with a second connecting surface 23 parallel to the first direction. The second connecting surface 23 is provided with a second mating hole 231. The second connecting through hole 631 is aligned with the second mating hole 231 so that the second connecting surface 23 is bolted to the second connecting plate 63.

[0051] Thus, the first connecting surface 13 can be bolted to the first connecting plate 61, and the second connecting surface 23 can be bolted to the second connecting plate 63, thereby connecting the machine tool connector 60 to the machining bed 10 and the blanking bed 20. In addition, since the first connecting plate 61 and the second connecting plate 63 are perpendicular to each other, and the first connecting surface 13 and the second connecting surface 23 are perpendicular to each other, before bolting the machine tool connector 60 to the blanking bed 20 and the machining bed 10, the machine tool connector 60 can be positioned by abutting against the first connecting surface 13 and the second connecting surface 23, which facilitates the installation of the machine tool connector 60.

[0052] Understandably, the machining bed 10 may include two first connecting surfaces 13 arranged sequentially along a direction perpendicular to the first direction. The unloading bed 20 may include two second connecting surfaces 23, which are arranged in a one-to-one correspondence with the two first connecting surfaces 13. The laser processing device 100 may include two machine tool connectors 60, which respectively connect one first connecting surface 13 and one second connecting surface 23. In this way, the unloading bed 20 and the machining bed 10 can be connected more securely.

[0053] It is worth noting that the machine tool connector 60 may include a plurality of first connecting through holes 611, which may be arranged along a first direction or at an angle to the first direction; this application does not impose specific limitations on this arrangement. The machine tool connector 60 may also include a plurality of second connecting through holes 631, which may be arranged in a direction perpendicular to the first direction; this application does not impose specific limitations on this arrangement either.

[0054] Understandably, the blanking bed 20 may also be provided with a third connecting surface perpendicular to the first direction, which is used to abut against the first connecting surface 13. In this way, the position of the first connecting surface 13 with the first mating hole 131 is bolted to the machine tool connector 60, and the position of the first connecting surface 13 without the first mating hole 131 can abut against the third connecting surface, further increasing the stability of the connection between the blanking bed 20 and the machining bed 10.

[0055] This utility model embodiment also provides a laser processing device, which includes a laser processing apparatus 100. The specific structure of the laser processing apparatus 100 is as described in the above embodiments. Since this laser processing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments.

[0056] In this embodiment of the laser processing equipment, the installed and debugged conveying assembly 30 can be disassembled. Specifically, the first chain section 311 and the second chain section 313 are disassembled, the first chain section 311 is connected to the first mounting section 11, the second chain section 313 is connected to the second mounting section 21, and the processing bed 10 and the unloading bed 20 are separated, thereby realizing the separate transportation of the processing bed 10 and the unloading bed 20. After transportation is completed, the connection between the first chain section 311 and the first mounting section 11 is released, the connection between the second chain section 313 and the second mounting section 21 is released, and the first chain section 311 and the second chain section 313 are reconnected. The unloading bed 20 is then reconnected to the processing bed 10. This ensures that the transmission between the processing bed 10 and the unloading bed 20 is not interrupted due to the discontinuity of the conveying assembly 30, and also reduces the debugging steps required after transportation, facilitating the transportation of the laser processing device 100.
