Description

Technical Field

[0001] The invention relates to the field of plate cutting, and in particular to a plate cutting and sorting system and method. Background Art

[0002] In the prior art, laser cutting devices are often used to accurately cut plates to cut out products of different shapes. When in use, the laser cutting device needs to be equipped with a loading mechanism and a unloading mechanism. Traditional loading mechanisms, unloading and sorting mechanisms, and laser cutting devices occupy a large space and have an unreasonable layout. The efficiency of loading, cutting, unloading and sorting of plates is low, and during the cutting process, the dust and smoke generated are not discharged in time, which will pollute the environment on the one hand, and on the other hand, these dust and smoke will fall on the plates to be cut at the loading mechanism, which will affect the precise cutting of the plates. These dust and smoke will also fall on the cut products, which causes the surface of the products to be contaminated. The contaminated products also require some cleaning equipment to clean the products.

[0003] For example, Chinese patent 202210678381.3 discloses an automatic loading and unloading and sorting production device for cutting large panel materials, which includes a conveyor line, a material preparation unit, a loading and unloading truss unit, a large-format cutting machine, a large-piece sorting unit, a slag removal unit, a leveling unit, a coding offline unit and a central control system. The conveyor line includes a primary sorting section, a buffer section, a slag removal section, a leveling section and a secondary sorting section arranged in sequence. The device adopts a unidirectional layout, so that the length space occupied by the entire device is very large. In addition, during a plate cutting process, the sorting mechanism and the loading and unloading truss unit are all in a stopped state. When the cutting is completed, the sorting mechanism needs to sort the product, and the loading and unloading truss unit needs to pick up the waste. During these processes, the large-format cutting machine is in a stopped state. Only when the products and waste on the large-format cutting machine are picked up, can a plate be placed on the large-format cutting machine again. The downtime of each mechanism in the above process is too long, which leads to low production efficiency. Moreover, the device of this patent does not promptly and effectively discharge the smoke and dust generated during the cutting process, which may cause the dust and smoke to fall on the plate to be cut, affecting the cutting accuracy, and may also cause the smoke and dust to fall on the product, requiring the product to be thoroughly cleaned. Summary of the invention

The bottom of the frame 200 is sequentially provided with a first area 201, a second area 202 and a third area 203 along the X direction, wherein the first area 201 is a plate storage area. The laser cutting device 100 includes a base, wherein the base includes a cutting area and a loading and unloading area, wherein the loading and unloading area of ​​the base is located in the second area 202, and the cutting area is located outside the loading and unloading area along the Y direction, and the laser cutting device 100 also includes an upper workbench 101 and a lower workbench 102 that reciprocate between the cutting area and the loading and unloading area, wherein the upper workbench 101 and the lower workbench 102 can be driven by a traction block on a belt driven by a motor assembly. The lower workbench 102 is located below the upper workbench 101. The third zone 203 is provided with an AGV transport vehicle 600 that moves along the Y direction and a waste transport vehicle 500 that moves along the Y direction. The AGV transport vehicle 600 can move to the bottom of the waste transport vehicle 500. The transfer mechanism 300 is used to pick up the plates in the first zone 201 and place them on the upper workbench 101 or the lower workbench 102 located in the second zone 202. The transfer mechanism 300 is also used to pick up the waste on the upper workbench 101 or the lower workbench 102 and place them on the waste transport vehicle 500 in the third zone 203. The unloading sorting mechanism 400 is used to pick up the products on the upper workbench 101 or the lower workbench 102 by category and stack them on the AGV transport vehicle 600 in the third zone 203. Figure 6 and Figure 7 As shown, the laser cutting device 100 also includes a smoke exhaust assembly arranged in the cutting area of ​​the base, and the smoke exhaust assembly includes a plurality of partition plates 103 arranged at the bottom of the base, each partition plate 103 is divided into a plurality of smoke exhaust areas 104, and a smoke exhaust port 105 is arranged on the base on one side of each smoke exhaust area 104, and a rotatable damper is arranged at each smoke exhaust port 105, and the damper is connected to the damper drive assembly, and the damper drive assembly can be connected to a cylinder assembly or a motor assembly, etc. Each smoke exhaust port 105 is connected to a smoke outlet branch pipe arranged on the base, and the smoke outlet branch pipe is connected to a smoke outlet main pipe across the base, and a main smoke outlet 106 is arranged on the smoke outlet main pipe, and the main smoke outlet 106 is connected to a fan filter assembly, and the fan filter assembly is arranged on the outside of the base.

[0032] Specifically, the first area 201 can stack plates, and the transfer mechanism 300 transfers a plate from the first area 201 to the upper workbench 101 of the second area 202, and the upper workbench 101 transfers the plate to the cutting area of ​​the laser cutting device 100 for cutting. At this time, the transfer mechanism 300 transfers the second plate to the lower workbench 102 of the second area 202. When the plate on the upper workbench 101 is cut, different types of products and waste are formed on the upper workbench 101. After the upper workbench 101 moves to the second area 202, the lower workbench 102 transfers the second plate to the cutting area of ​​the laser cutting device 100 for cutting. When cutting the plates on the workbench, only the damper corresponding to the exhaust area 104 where the laser cutting head is located is in the open state, and the dampers corresponding to other exhaust areas 104 are all closed. When the plate on the lower workbench 102 is cut, the products on the upper workbench 101 can be sorted and the waste can be transferred. Specifically, the waste transport vehicle 500 first moves to the outside of the third area 203, and the unloading sorting mechanism 400 picks up different types of products on the upper workbench 101 and places them on the AGV transport vehicle 600 in the third area 203. After the AGV transport vehicle 600 in the third area 203 leaves the third area 203, the waste transport vehicle 500 moves to the third area 203, and the transfer mechanism 300 picks up the waste on the upper workbench 101 and places it on the waste transport vehicle 500. When there are no products or waste on the upper workbench 101, a new plate to be cut can be placed on the upper workbench 101 from the first area 201 through the transfer mechanism 300.

[0033] On the basis of the above, a circle of isolation plates can be arranged around the base of the laser cutting device 100, and an opening can be arranged on the isolation plate facing the second zone 202 for movement of the upper workbench 101 and the lower workbench 102.

When cutting the plate, only the damper corresponding to the exhaust zone 104 where the laser cutting head is located is in an open state, and the dampers corresponding to other exhaust zones 104 are all in a closed state.

[0035] Specifically, in the above configuration, other dampers are in a closed state, and only the damper corresponding to the smoke exhaust area 104 where the laser cutting head is located is in an open state, so that all suction forces can be concentrated in this area, which is conducive to quickly sucking out dust and smoke.
