The present inventors diligently studied the laser device and obtained the following recognition. That is, in the conventional laser apparatus, it is common to accommodate various units in a 19-inch standard cabinet (rack). Various units are housed in a cabinet so that they can be inserted and removed, and each unit is pulled out of the cabinet for maintenance. As a matter of course, the outer wall of the cabinet is designed to be slightly larger than the overall size of the various units accommodated. For this reason, the conventional laser device has to have a large installation area. As an example, the installation area of the conventional laser device is about 600 mm × 1000 mm.

In addition, when a laser apparatus having a large installation area is installed in the laser processing machine, there is a case where the flow line of the worker around the laser processing machine becomes an obstacle. For this reason, the laser apparatus has been installed at a predetermined distance from the laser processing machine in order to ensure the flow of the operator around the laser processing machine. Therefore, the conventional laser apparatus is not only the size of the installation area of itself, but also is a factor that lowers the space efficiency when laying the laser apparatus and the laser processing machine due to the arrangement away from the laser processing machine. It was.

In addition, the present inventors diligently studied the laser device and obtained the following recognition. That is, in the conventional laser apparatus, in order to improve the cooling efficiency of each unit, a panel cooler is provided in the cabinet and the cold air is circulated in the cabinet. However, a large and expensive cooler is required to cool the entire cabinet. The installation of such a cooler can be a factor in increasing the size of the laser device. In addition, the cost of the laser device can be increased.

As a method of cooling each unit without using a cooler, it is conceivable to provide a heat exchanger in the cabinet and cool each unit with cooling water supplied from the outside. However, when various units are cooled by a common water cooling mechanism, an expensive heat exchanger or the like is required, which can lead to an increase in the cost of the laser device.

The present invention has been made in view of such circumstances, and one of its purposes is to provide a technique for improving space efficiency when laying a laser device and a laser processing machine. Another object of the present invention is to provide a technique for achieving both reduction in size and cost of a laser device.

An embodiment of the present invention is a laser device cabinet. The cabinet is a laser device cabinet for housing a laser module that oscillates a laser, a power supply module that supplies power to the laser module, and a laser control unit that controls the driving of the laser module. Regarding the dimensions in the direction, the second direction, and the third direction, the dimension in the first direction is 1/3 or less of the smaller dimension of the dimension in the second direction and the dimension in the third direction.

Another aspect of the present invention is a laser device. The laser apparatus includes a laser module that oscillates a laser, a power supply module that supplies power to the laser module, a laser control unit that controls driving of the laser module, and the laser module, the power supply module, and the laser control unit. And a laser device cabinet.

Another aspect of the present invention is a laser device. The laser device includes a laser module that oscillates a laser, a power supply module that supplies power to the laser module, a water cooling mechanism for cooling the laser module, and an air cooling mechanism for cooling the power supply module.

FIG. 4 (A) is a perspective view schematically showing a state in which a conventional laser device is connected to a laser processing machine. FIG. 4B is a perspective view schematically showing a state where the laser apparatus according to Embodiment 1 is connected to the laser processing machine. As shown in FIG. 4A, in the conventional laser apparatus 100, various units are housed in a 19-inch standard cabinet. For this reason, the installation area of the laser apparatus 100 was relatively large. Further, when the laser apparatus 100 having a large installation area is provided in the laser processing machine 200, it may become an obstacle to the flow line of the worker around the laser processing machine 200. For this reason, the laser apparatus 100 is installed at a predetermined distance from the laser processing machine 200 so that an operator can pass between the laser apparatus 100 and the laser processing machine 200.

On the other hand, as shown in FIG. 4B, the laser device 1 according to the present embodiment has a thinner shape than the conventional laser device 100. For this reason, an installation area can be made smaller than the conventional laser apparatus 100. FIG. Further, even when the laser apparatus 1 is placed vertically so that the main surface 8d of the cabinet 8 is in contact with or close to the laser processing machine 200, the laser processing can be performed even when the laser apparatus 1 is provided in the laser processing machine 200. An operator's flow line around the machine 200 can be secured. In other words, the laser apparatus 1 according to the present embodiment has the small installation area and can be installed so as to be in contact with or close to the laser processing machine 200, so that the laser apparatus 1 and the laser processing machine 200 are installed. Space efficiency can be improved. For example, when the laser processing machine 200 has a dead space, the laser apparatus 1 can be accommodated in this space. At this time, the laser device 1 can also be placed horizontally so that the main surface 8d of the cabinet 8 faces in the vertical direction.

As described above, the cabinet 8 for a laser apparatus according to the present embodiment is such that the dimension in the first direction A is the dimension in the second direction B with respect to the dimensions in the first direction A to the third direction C orthogonal to each other. And it is 1/3 or less of the dimension of the smaller one among the dimensions of the third direction C. Therefore, the cabinet 8 has a flat main shape and a pair of main surfaces 8d facing each other. Thus, the installation space of the laser apparatus 1 can be reduced by making the cabinet 8 thin in the first direction A. Moreover, the degree of freedom of installation of the laser device 1 can be increased by reducing the installation space of the laser device 1. As a result, space efficiency when laying the laser device 1 and the laser beam machine 200 can be improved. In particular, in the actual usage situation of the laser apparatus 1, the space efficiency is reduced by setting the smallest dimension in the first direction A to be １／ or less of the dimension in the second smallest second direction B or the third direction C. It can improve more reliably.

Further, the laser module 2 is a flat shape and has a pair of main surfaces 2a facing each other. The laser module 2 is arranged such that its main surface 2 a extends in parallel to the main surface 8 d of the cabinet 8. Further, the laser module 2 and at least one of the power supply module 4 and the laser control unit 6 are arranged so as to be shifted in the second direction B and / or the third direction C. Thus, the cabinet 8 and thus the laser device 1 can be easily thinned. Moreover, the laser module 2, the power supply module 4, and the laser control part 6 are separately housed, that is, housed in the cabinet 8 in a state where they are not housed in one package. This also makes it easy to make the cabinet 8 and thus the laser device 1 thinner.

Further, the laser device 1 includes a water cooling mechanism for cooling the laser module 2 and an air cooling mechanism for cooling the power supply module 4. In the conventional laser apparatus, there are cases where the entire unit is blown to cool each unit in a lump. In addition, in order to improve the cooling efficiency of each unit, a panel cooler is provided in the cabinet to circulate cold air in the cabinet. However, in order to cool the entire inside of the cabinet, a relatively large and expensive cooler is required. For this reason, it can be an obstacle to miniaturization of the laser device. In addition, the cost of the laser device can be increased.

As a method of cooling each unit without using a cooler, it is conceivable to provide a heat exchanger in the cabinet and cool each unit with cooling water supplied from the outside. However, when the laser module 2 and the power supply module 4 which are main heating elements in the laser apparatus 1 are cooled by a common water cooling mechanism, an expensive heat exchanger or the like is required, which may increase the cost of the laser apparatus. .

In contrast, in the laser apparatus 1 of the present embodiment, the laser module 2 is cooled by a water cooling mechanism including a manifold 14 and the power supply module 4 is cooled by an air cooling mechanism including an exhaust fan 34 and the like. Thus, about the laser module 2 and the power supply module 4 which are main heat generating bodies, one can be water-cooled and the other can be air-cooled, so that the cooler can be omitted or reduced in size, and an expensive heat exchanger can be used. Can be avoided. Therefore, it is possible to achieve both reduction in size and cost of the laser device 1. Further, unlike the case where the entire cabinet 8 is air-cooled, it is not necessary to arrange the units in consideration of the air flow, so that the degree of freedom of arrangement of the units in the cabinet 8 can be increased.

Further, in the present embodiment, a water cooling mechanism having higher cooling efficiency than the air cooling mechanism is applied to the laser module 2 that is required to have higher temperature stability than the power supply module 4. Thereby, the stability of the laser output in the laser apparatus 1 can be improved.

The interior of the cabinet 8 is partitioned into a first space R1 in which the laser module 2 and the like are accommodated, and a second space R2 in which the power supply module 4 is accommodated. Of the units accommodated in the first space R1, the laser module 2 as the main heating element is cooled by the water cooling mechanism. Thereby, the temperature rise of the other unit in 1st space R1 is suppressed. In addition, all the units accommodated in the first space R1 may be water-cooled. Further, the cabinet 8 is provided with an intake port 28 for taking outside air into the second space R2 and an exhaust port 30 for exhausting the air from the second space R2 to the outside. Thereby, the power supply module 4 accommodated in 2nd space R2 is air-cooled. An exhaust fan 34 is provided at the exhaust port 30. Thereby, the cooling efficiency of the power supply module 4 can be improved.

FIG. 4B is a perspective view schematically showing a state in which the laser apparatus according to Embodiment 2 is connected to the laser processing machine. As shown in FIG. 4A, in the conventional laser apparatus 100, various units are housed in a 19-inch standard cabinet. For this reason, the installation area of the laser apparatus 100 was relatively large. Further, when the laser apparatus 100 having a large installation area is provided in the laser processing machine 200, it may become an obstacle to the flow line of the worker around the laser processing machine 200. For this reason, the laser apparatus 100 is installed at a predetermined distance from the laser processing machine 200 so that an operator can pass between the laser apparatus 100 and the laser processing machine 200.

As described above, the laser apparatus 1 according to the present embodiment includes the water cooling mechanism for cooling the laser module 2 and the air cooling mechanism for cooling the power supply module 4. As described above, the laser module 2 and the power supply module 4 which are the main heating elements in the laser apparatus 1 can be cooled or omitted in size by cooling one of them with water and the other with air. The use of an exchanger can be avoided. Therefore, it is possible to achieve both reduction in size and cost of the laser device 1. Further, unlike the case where the entire cabinet 8 is air-cooled, it is not necessary to arrange the units in consideration of the air flow, so that the degree of freedom of arrangement of the units in the cabinet 8 can be increased.

The cabinet 8 has a dimension in the first direction A to the third direction C orthogonal to each other, and the dimension in the first direction A is the smaller of the dimension in the second direction B and the dimension in the third direction C. 1/3 or less. Therefore, the cabinet 8 has a flat main shape and a pair of main surfaces 8d facing each other. Thus, the installation space of the laser apparatus 1 can be reduced by making the cabinet 8 thin in the first direction A. Moreover, the degree of freedom of installation of the laser device 1 can be increased by reducing the installation space of the laser device 1. As a result, space efficiency when laying the laser device 1 and the laser beam machine 200 can be improved. In particular, in the actual usage situation of the laser apparatus 1, the space efficiency is reduced by setting the smallest dimension in the first direction A to be １／ or less of the dimension in the second smallest second direction B or the third direction C. It can improve more reliably.

In the above-described embodiment, the arrangement of each unit can be changed as appropriate within a range in which the cabinet 8 can be thinned. In addition, the arrangement of the units can be changed as appropriate as long as the water cooling of the laser module 2 and the air cooling of the power supply module 4 can be realized. Further, when the cabinet 8 does not need to have a dustproof and waterproof structure, the bush and the seal member can be omitted.
