Description

Technical Field

[0001] The invention relates to the field of laser cutting, in particular to an exchange platform laser cutting device. Background Art

[0002] The exchange platform laser cutting device is a device designed for plate cutting. The device generally has two platforms, and the two platforms can place plates respectively, and the plates on the platforms are cut by the laser cutting head.

[0003] The existing exchange platform laser cutting device has the following shortcomings: Chinese patent 202310642901.X discloses a large-format dual-exchange work platform laser cutting machine and its exchange method. In order to ensure that the two platforms used in the patent maintain the same height after the exchange, it is necessary to use a lifting cylinder to adjust the platform height. Since multiple lifting cylinders are needed to adjust the platform height, the overall structure is relatively complex, and it is necessary to ensure that the lifting height of each lifting cylinder is consistent, which makes the operation difficult and has a high failure rate.

[0004] Chinese patent 201510850154.4 discloses a laser cutting machine for exchanging platforms. In order to make the heights of the two platforms consistent after the exchange, two U-shaped rails are set in the device. Since the U-shaped rails are in the shape of bars, in order to prevent the two U-shaped rails from interfering with each other, the two U-shaped rails are not at the same height during installation, one U-shaped rail is high and the other is low. This results in the inconsistency of the heights of the front legs and rear legs of the platform running on the U-shaped rails, which brings great difficulty to processing and installation. A high processing accuracy is required to ensure that the lengths of the front legs and rear legs match the corresponding U-shaped rails. If the processing accuracy is not high or the installation accuracy is insufficient, the platform will be bumpy and unstable.

[0005] Moreover, when the platform in the patent moves on the U-shaped guide rail, it first descends from the horizontal section to a lower position, then runs a certain distance at the lower position and then rises to the higher horizontal section, which will cause a lot of space at the bottom of the rack to be occupied and the space at the bottom of the rack cannot be used. The smoke exhaust system of the patent can only be installed at the laser head on the beam across the rack. However, this smoke exhaust system that moves with the laser head is small in size and has weak smoke exhaust capacity. It is located above the plate to be cut and is far away from the plate. However, the position with relatively high smoke concentration is generally located near the plate and the bottom area of ​​the rack. Therefore, the smoke exhaust capacity of this exchange platform is very poor.

[0006] Chinese patent 202221599893.2 discloses a laser cutting machine with dust removal and smoke extraction and exchangeable working platform functions. In order to facilitate smoke and dust exhaust, the patent sets the dust removal and smoke extraction mechanism on the mobile mechanism. The two platforms do not move, and the mobile mechanism moves back and forth between the two platforms to cut the plates on the two platforms. In this setting method, it is necessary to set up feeding mechanisms on the outside of the two platforms to feed the two platforms, which increases the number of feeding mechanisms, making the overall equipment occupy a large area and requiring more auxiliary equipment. Moreover, since the dust removal and smoke extraction mechanism is set on the mobile mechanism, the fan and other components also need to be installed on the mobile mechanism, which results in the fan volume not being too large, the power not being too large, the adsorption capacity being relatively small, and the smoke exhaust effect being poor. Moreover, the impurity particles in the smoke will gather in the dust removal and smoke extraction mechanism, which will cause the weight of the mobile mechanism to change continuously, affect the smooth operation of the mobile mechanism, and affect the cutting accuracy. Moreover, since the dust removal and smoke extraction mechanism set on the mobile mechanism is relatively small in volume, the amount of smoke particles that can be accommodated is relatively small, which requires frequent shutdowns to clean the dust removal and smoke extraction mechanism. Time-consuming and laborious. Summary of the invention

When the climbing platform and the translation platform are interlaced, the climbing platform is above the translation platform, and the climbing platform will not occupy the bottom space of the rack, so that the bottom space of the first area of ​​the rack can be released.

The frame 101 is also provided with the driving mechanism 106, which is respectively connected to the translation platform 104 and the climbing platform 105, and is used to drive the translation platform 104 and the climbing platform 105 to move synchronously in opposite directions. The bottom of the frame 101 corresponding to the first area 109 is provided with a plurality of partitions 116 to form a plurality of smoke exhaust sub-areas 111. The partitions 116 can be arranged horizontally and vertically, so that one area can be divided into a plurality of smoke exhaust sub-areas 111. A smoke exhaust port 112 is provided on the frame 101 corresponding to one side of each smoke exhaust sub-area 111. Each smoke exhaust port 112 is connected to a smoke exhaust pipe. A total air outlet 115 is provided on the smoke exhaust pipe. A damper 113 and a damper driving assembly 114 for driving the damper 113 to open and close are provided at the smoke exhaust port 112.

[0040] Specifically, the damper 113 is rotatably mounted at the smoke exhaust port 112, and one end of the damper 113 is connected to a damper driving assembly 114, which can be a cylinder driving mechanism 106 or a motor driving mechanism 106.

When the climbing platform 105 and the translation platform 104 are interlaced, the climbing platform 105 is located above the translation platform 104 under the guidance of the climbing track 102. When the climbing platform 105 moves into the first area 109, it can be lowered to the same height as the translation platform 104. At this time, the translation platform 104 is located in the second area 110. Then, the plate on the climbing platform 105 can be cut.

[0050] Specifically, the translation track 103 is composed of two plates, and the two plates are respectively arranged on the inner side of the corresponding first type plate 1021. In this way, from the inside to the outside, there are the plate of the translation track 103, the first type plate 1021, and the second type plate 1022. The connecting block 1041 can be arranged between the plate of the translation track 103 and the first type plate 1021, and between the first type plate 1021 and the second type plate 1022.
