Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, and relates to a positioning device and a laser cutting device for laser cutting of aluminum plates. Background Art

[0002] Laser cutting is to use a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, and vaporizes to form holes. As the beam moves relative to the material, the holes continuously form a slit with a very narrow width (such as about 0.1 mm), completing the cutting of the material.

[0003] During the processing of aluminum plates, a laser cutting device is often used to cut the aluminum plates. Before cutting, a positioning device is generally used to position the aluminum plates for subsequent cutting of the aluminum plates. However, the existing positioning devices are difficult to accurately clamp the aluminum plates, resulting in insecure clamping of the aluminum plates. In addition, the existing positioning devices are not convenient for determining the cutting sites of the aluminum plates, and it is not convenient for workers to judge the accuracy of the laser cutting component cutting the aluminum plates. Therefore, there is an urgent need for a positioning device and a laser cutting device for laser cutting of aluminum plates to solve the above problems. Summary of the Utility Model

[0004] In view of the above technical problems existing in the prior art, a positioning device and a laser cutting device for laser cutting of aluminum plates are provided. The distance measuring component can measure the moving displacement of the clamping plate, which is beneficial to accurately and firmly clamping the aluminum plate by the two clamping plates. When the optical positioning component works, it will generate light points corresponding to the cutting sites of the aluminum plate, which is convenient for workers to quickly find the cutting sites of the aluminum plate, and can also quickly judge the accuracy of the laser cutting component cutting the aluminum plate. The slag on the bracket can be removed in time, which is beneficial to the stable placement of the aluminum plate on the bracket in the later stage.

[0005] The purpose and effect of the utility model are achieved by the following specific technical means:

[0006] A positioning device for laser cutting of aluminum plates includes a pair of clamping components. Each clamping component includes an electric push rod and a clamping plate installed at the output end of the electric push rod.

[0007] A distance measuring component facing the clamping plate is arranged beside each electric push rod. A notch is formed at the bottom of the clamping plate, a scraping blade is fixed in the notch, a strip-shaped groove is formed at the clamping end of the clamping plate, and an optical positioning component for cutting site positioning is installed in the strip-shaped groove.

[0008] Further, the distance measuring component includes a laser rangefinder.

[0009] Further, the optical positioning component includes an LED display screen and a transparent baffle. The LED display screen and the transparent baffle are respectively installed inside and outside the strip-shaped groove.

[0010] Further, the transparent baffle is a transparent PC plastic plate.

[0011] The present utility model also provides a laser cutting device, including the above-mentioned positioning device for laser cutting of aluminum plates, a machine body, and a PLC controller installed on the machine body. A bracket is installed inside the machine body. The clamping plate is slidably connected to the bracket through a plurality of the notches. A plurality of dust discharge ports are formed in the middle part of the bracket. The scraping blades are all in contact with the upper surface of the bracket. Two installation grooves are formed on both sides of the inner wall of the machine body. The electric push rods and the distance measuring components are respectively installed in the two installation grooves on the same side.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] For this positioning device for laser cutting of aluminum plates, the distance measuring component can measure the moving displacement of the clamping plate, which is beneficial for firmly clamping the aluminum plate by the two clamping plates. The optical positioning component cooperates with the PLC controller on the laser cutting device. When the optical positioning component works, light spots corresponding to the cutting positions of the aluminum plate will be generated, which is convenient for the staff to quickly find the cutting positions of the aluminum plate. The staff can also observe whether the laser cutting component on the laser cutting device is aligned with the light spots, and can quickly judge the accuracy of the laser cutting component in cutting the aluminum plate;

[0014] Since aluminum slag will be generated during the process of the laser cutting component cutting the aluminum plate, and these aluminum slags will fall on the bracket, after the machine body is used, the staff can click the PLC controller to start the two electric push rods to work continuously for a period of time, which can drive the clamping plate to reciprocate on the bracket. Several scraping blades at the bottom of the clamping plate can scrape up the aluminum slag on the bracket. When the scraping blades move to the dust discharge ports, the aluminum slag scraped up on the bracket will be pushed into the dust discharge ports, which can timely remove the slag from the bracket and is beneficial for stably placing the aluminum plate on the bracket in the later stage.

[0020] Please refer to Figures 1-4 , and make a further description of the embodiments of the present invention;

[0021] A positioning device for laser cutting of aluminum plates includes a pair of clamping components. The clamping components include an electric push rod 5 and a clamping plate 7 installed at the output end of the electric push rod 5;

[0022] A ranging component facing the clamping plate 7 is arranged beside the electric push rod 5. A notch 12 is opened at the bottom of the clamping plate 7, and a scraping blade 8 is fixed in the notch 12. A strip groove 9 is opened at the clamping end of the clamping plate 7, and an optical positioning component for positioning the cutting site is installed in the strip groove 9;

[0023] In this embodiment, as Figure 1 shown, this positioning device is used in a laser cutting device. The laser cutting device includes a body 1 and a PLC controller 3 installed on the body 1. The electric push rod 5, the ranging component, and the optical positioning component are all electrically connected to the PLC controller 3. A bracket 2 is installed inside the body 1. The clamping plate 7 is slidably connected to the bracket 2 through a plurality of notches 12. A plurality of dust exhaust ports 13 are opened in the middle part of the bracket 2. The scraping blades 8 are all in contact with the upper surface of the bracket 2, and two installation grooves 4 are opened on both sides of the inner wall of the body 1. The electric push rod 5 and the ranging component are respectively installed in the two installation grooves 4 on the same side;

[0024] Before using this positioning device, the working intermittent time of the electric push rod 5, the ranging component, and the optical positioning component can be preset through the PLC controller 3. It is also possible to set multiple cutting sites of the aluminum plate to correspond to multiple light points emitted by the optical positioning component, as well as the distance value of the ranging component, that is, the displacement value of the clamping plate 7;

[0025] A pair of clamping components are in an open state initially. The staff can place the aluminum plate at the designated position on the bracket 2, and then power on the electric push rod 5, the distance measuring component, and the optical positioning component. The electric push rod 5 will drive the clamping plate 7 connected to it to move on the bracket 2. During this process, the distance measuring component will measure the displacement value of the clamping plate 7, and the data measured by the distance measuring component will be transmitted to the PLC controller 3. When the distance value obtained by the PLC controller 3 is equal to the preset distance value, the PLC controller 3 will turn off the electric push rod 5. At this time, the two clamping plates 7 firmly clamp the aluminum plate. Then, the PLC controller 3 will start the optical positioning component. When the optical positioning component works, it will generate light points corresponding to the cutting points of the aluminum plate, which is convenient for the staff to quickly find the cutting points of the aluminum plate. There is also a laser cutting component provided on the machine body 1. After that, the laser cutting component will move to the cutting point of the aluminum plate. At this time, the staff can observe whether the laser cutting component is aligned with the light point, and can quickly judge the accuracy of the laser cutting component cutting the aluminum plate;

[0026] After the machine body 1 is used up, since aluminum slag will be generated during the process of the laser cutting component cutting the aluminum plate, these aluminum slag will fall on the bracket 2. At this time, the staff can click the PLC controller 3 to start the two electric push rods 5 to work continuously for a period of time, which can drive the clamping plate 7 to make a reciprocating motion on the bracket 2. It should be noted that the two electric push rods 5 are started successively to avoid the two clamping plates 7. Therefore, several scraping blades 8 at the bottom of the clamping plate 7 can scrape the aluminum slag on the bracket 2 and fall it into the machine body 1. When the scraping blade 8 moves to the dust exhaust port 13, the aluminum slag scraped up on the bracket 2 will be pushed into the dust exhaust port 13.

[0027] The distance measuring component is preferably a laser rangefinder 6, and the laser rangefinder 6 has stable measurement and accurate measurement results.

[0028] The optical positioning component includes an LED display screen 10 and a transparent baffle 11. The LED display screen 10 and the transparent baffle 11 are respectively installed inside and outside and are both installed in the strip-shaped groove 9;

[0029] In this embodiment, the LED display screen 10 is electrically connected to the PLC controller 3. When the optical positioning component works, the LED display screen 10 will generate light points corresponding to the cutting points of the aluminum plate, which is convenient for the staff to quickly find the cutting points of the aluminum plate, and can also observe whether the laser cutting component is aligned with the light points, and can quickly judge the accuracy of the laser cutting component cutting the aluminum plate.

[0030] The transparent baffle 11 is preferably a transparent PC plastic plate, which has high hardness, good light transmittance, is more durable, and has better use effects.

[0031] The present utility model also provides a laser cutting device, which includes the above-mentioned positioning device for laser cutting of aluminum plates, a machine body 1, and a PLC controller 3 installed on the machine body 1. A bracket 2 is installed inside the machine body 1. The clamping plate 7 is slidably connected to the bracket 2 through a plurality of notches 12. A plurality of dust discharge ports 13 are formed in the middle part of the bracket 2. The scraping blades 8 are all in contact with the upper surface of the bracket 2. Two installation grooves 4 are formed on both sides of the inner wall of the machine body 1. The electric push rod 5 and the distance measuring component are respectively installed in the two installation grooves 4 on the same side;

[0032] In this embodiment, the use of the laser cutting device and the positioning device for laser cutting of aluminum plates has been described in the above embodiment, and will not be elaborated here. The distance measuring component in the positioning device for laser cutting of aluminum plates can measure the moving displacement of the clamping plate 7, which is beneficial for the two clamping plates 7 to firmly clamp the aluminum plate. When the optical positioning component works, light spots corresponding to the cutting positions of the aluminum plate will be generated, which is convenient for the staff to quickly find the cutting positions of the aluminum plate, and can also quickly judge the accuracy of the laser cutting component in cutting the aluminum plate. When the electric push rod 5, the clamping plate 7 and the scraping blade 8 are used together, the slag on the bracket 2 can be removed in time, which is beneficial for the aluminum plate to be stably placed on the bracket in the later stage.
