Description

Technical Field

[0001] The present invention relates to the technical field of electrical cabinet plate processing, in particular to a laser cutting device for electrical cabinet production. Background Art

[0002] Electrical cabinets are often used for line control, protection, or monitoring, and are crucial electrical equipment in power systems. Cutting is required during the processing of electrical cabinet panels. Laser cutting technology utilizes a high-energy-density laser beam to cut materials. A laser cutting machine uses a laser beam generated by a laser and focuses it onto a very small point through an optical system, causing the material to be locally heated and melted or vaporized. The melted or vaporized material is then blown away with an auxiliary gas, achieving the desired cutting effect.

[0003] After searching, the Chinese patent with the publication number CN222660454U discloses a laser cutting machine that cuts plates using a three-axis laser cutting machine. However, the following problems still exist:

[0004] 1. There is no protective cover during cutting, and the gas generated during cutting is easily blown into the working space by high-pressure auxiliary gas, causing pollution;

[0005] 2. It is not suitable for cutting lightweight thin plates such as electrical cabinet plates, because the electrical cabinet plates are thin, and the cutting groove is easy to sink downward during cutting. The deformation of the plate during cutting will make it impossible to cut according to the original layout;

[0006] 3. It is impossible to discharge the toxic gas generated during cutting, and the accumulation of gas will cause harm to the health of workers. Summary of the Invention

[0020] Beneficial effects

[0021] Compared with the prior art, the present invention provides a laser cutting device for electrical cabinet production, which has the following beneficial effects:

[0022] 1. The present invention covers the entire laser cutting machine through the outer cover body, thereby improving the safety of the operation and avoiding the exhaust gas generated by laser cutting from polluting the environment of external personnel as much as possible. The cutting status of the internal plate can be observed in real time through the observation window opened on the outer cover body, and intervention can be made before and during cutting through the operation port.

[0024] 3. The present invention can pull the upper fixed plate through the inclined hook spring in the fixing mechanism. When the plate to be cut moves between the lower fixed plate and the fixed plate, the action of the hook spring generates an oblique downward pulling force. This pulling force has two practical effects on the edge of the plate. One is to press the plate tightly, and the other is to straighten the plate, so that the plate can be cut according to the pre-arranged plan.

[0025] 4. The present invention uses a driving mechanism to move the fixed plate laterally, and then cooperates with the transverse and longitudinal moving components to drive the lower laser cutting head to cut the plate installation layout plan. The laser cutting mechanism actually has only two axes, and a simple transverse moving component is used instead of three axes, which reduces the cost.

[0026] 5. The present invention connects a negative pressure device to two connection ports on the side of the substrate. After the negative pressure device is activated, the exhaust holes in the through groove will generate suction, which will absorb the exhaust gas generated by laser cutting, further reducing the harm to the workers.

[0039] It should be noted that the electrical cabinet plate conveying mechanism 2 includes a base plate 201 installed inside the outer cover body 1, and four groups of symmetrically arranged arc grooves 202 are opened inside the base plate 201, and a conveying roller 203 is installed inside the arc groove 202. The conveying roller 203 is an electric roller that can transport the plates above for loading and unloading.

[0040] In particular, in the present invention, the drive mechanism 3 includes two sets of side plates 301 welded and symmetrically fixed to the upper end of the base plate 201. Each set of side plates 301 is mounted with a drive motor 302, and bearings 304 are embedded in the inner sides of the side plates 301. A screw rod 305 is rotatably connected between the side plates 301 via the bearings 304. The outer side of the screw rod 305 is transmission-connected to a limit slider 306, which is provided with a fixing mechanism 4. The two drive motors 302 are synchronized by a controller, thereby enabling the limit sliders 306 on both sides to move synchronously.

[0041] It should be noted that two groups of symmetrically arranged limit slides 307 are welded and fixed to the upper end of the base plate 201, and a limit groove 308 is provided at the lower part of the limit slide 306. The limit slide 307 and the limit groove 308 are both T-shaped structures, and the limit slide 306 is sleeved on the outer side of the limit slide 307. A support wheel 303 is provided at the lower part of the limit slide 306, and the support wheel 303 is in contact with the upper surface of the limit slide 307, and a driving block 309 is integrally formed on the side of the limit slide 306, and a threaded seat 310 is integrally formed on the driving block 309. The threaded seat 310 is threadedly connected to the screw rod 305, and the support wheel 303 can allow the entire limit slide 306 and the inner fixing mechanism 4 and the plate fixed thereto to move smoothly.

[0042] In particular, in the present invention, the fixing mechanism 4 includes a fixing plate 411 welded and fixed to the inner side of the limiting slider 306, the outer sides of both ends of the fixing plate 411 are integrally formed with a lower fixing seat 401, the inner sides of both ends of the fixing plate 411 are integrally formed with a lower fixing plate 402, the upper part of the lower fixing seat 401 is integrally formed with a mounting groove 403, and the upper part of the lower fixing seat 401 is slidably connected with an upper fixing plate 404, and the sides of the mounting groove 403 and the upper fixing plate 404 are welded and fixed with fixing rings 405, and a hook spring 406 is hung between the fixing rings 405, and the hook spring 406 is a tension spring, which can generate an oblique downward pulling force on the upper fixing plate 404 fixed at its end to fix the plate.

[0043] It should be noted that four sets of rollers 407 are rotatably mounted on the lower end of the lower fixing seat 401, guide surfaces 408 are integrally formed on both sides of the lower fixing plate 402, and two sets of symmetrically arranged slots 409 are provided on the upper end of the lower fixing seat 401. The lower end of the upper fixing plate 404 is provided with a block 410 that cooperates with the slots 409. After cutting, the upper fixing plate 404 can be directly lifted up and removed through the operating port 103, thereby unlocking the sheet. After unlocking, the sheet will bend in the middle due to its own gravity, allowing it to be subsequently unloaded by the conveyor roller 203. The mounting slot 403 and the hook spring 406 are arranged at an angle.

[0044] In particular, in the present invention, the cutting groove structure 5 includes a through groove 501 horizontally arranged at the upper end of the substrate 201, and a plurality of exhaust holes 502 are arranged equidistantly inside the through groove 501. Two groups of symmetrically arranged connecting ports 204 are opened on the side of the substrate 201. The connecting ports 204 are connected to the exhaust holes 502. After the exhaust holes 502 are connected to the negative pressure device, suction will be generated to suck out the exhaust gas generated by laser cutting, thereby further reducing the harm to the staff.

[0045] It should be noted that the laser cutting mechanism 6 includes a transverse moving component 601 installed on the upper part of the base plate 201, and a longitudinal moving component 602 is installed on the transverse moving component 601, and a laser cutting head 603 is installed at the lower part of the longitudinal moving component 602.

[0046] The present invention is divided into the following steps when used:

[0047] S1: First, place the plate on the conveying roller 203, and start the conveying roller 203 through the operation panel 101 to convey the plate;

[0048] S2: Separate the upper fixing plate 404 and the hook spring 406, observe the output progress of the conveyor roller 203, and stop the operation of the conveyor roller 203 when the edge of the plate passes through the guide surface 408 on the lower fixing plate 402 and enters the lower fixing seat 401 at the tail;

[0049] S3: Adjust the position of the plate through the operation port 103 and hang the upper fixing plate 404 on the end of the hook spring 406. Then, insert the clamping block 410 at the bottom of the upper fixing plate 404 into the clamping groove 409 at the top of the lower fixing seat 401. The tension generated by the hook spring 406 presses the edge of the plate tightly and securely.

[0050] S4: Input the cutting layout plan into the computer in advance, and then start the laser cutting mechanism 6 to cut the plate through the operation panel 101. Before cutting, the external negative pressure device must be started first;

[0051] S5: After the cutting is completed, all internal electrical appliances are stopped through the operation panel 101, and then the upper fixed plate 404 is lifted through the operation port 103. The cut plate will fall due to its own gravity and contact the conveyor roller 203, and then the conveyor roller 203 is started to unload the plate through the operation panel 101.
