Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a dust suction structure of a laser cutting device. Background Art

[0002] Laser cutting technology is becoming increasingly sophisticated. Compared to other cutting processes, it has advantages such as fast cutting speed, high precision, and the ability to edit the cutting contour. Due to the process characteristics of laser cutting, a large amount of smoke and dust is generated during cutting. In order to reduce the residual smoke and dust that lead to product defects, the smoke and dust must be extracted during cutting. The current commonly used dust extraction solution is to install a large dust extraction nozzle above the product at the corresponding cutting position. However, there are the following shortcomings: 1. Because the dust extraction nozzle is a certain distance away from the cutting point, some smoke and dust cannot be completely extracted and adsorbed on the product; 2. This solution requires a large flow rate of negative pressure source, which consumes a lot of energy. Summary of the Invention

[0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a dust collection structure for a laser cutting device.

[0004] The purpose of the utility model is achieved through the following technical solutions: a dust suction structure of a laser cutting device, comprising a laser and a material tray arranged below the laser, and also comprising a movable module for driving the material tray to move forward, backward, left and right, a dust suction module arranged below the material tray, and a driving mechanism for driving the dust suction module to move up and down. A plurality of cutting areas are distributed in a rectangular array of the material tray, and a plurality of product units to be cut are placed in a rectangular array in each cutting area. One of the cutting areas is located between the laser and the dust suction module. The dust suction module comprises a suction nozzle and a dust suction mechanism. A dust suction groove is provided at the position of each product unit in one of the cutting areas of the suction nozzle, and the dust suction mechanism is connected to the bottom of each dust suction groove through a dust suction pipe.

[0005] Furthermore, a support block for supporting waste is fixed in each dust suction trough.

[0006] Furthermore, the plurality of dust collection slots arranged longitudinally are connected as one.

[0007] Furthermore, each of the dust suction grooves is provided with gaps on both sides.

[0008] The beneficial effects of the present invention are as follows: the dust suction structure of the laser cutting device of the present invention can absorb and flatten the product, providing a condition for convenient laser cutting; it can be close to the cutting position and adopt a matching dust suction groove to remove smoke and dust in time to avoid poor product appearance; the waste after cutting is sucked away through the dust suction pipe, which can prevent the product from being deformed due to the waste.

[0009] The dust suction structure of the laser cutting device of the present invention integrates the adsorption product and the extraction of smoke and dust into one, and the waste materials after cutting are sucked away through the dust suction pipe, which can effectively reduce the cutting rate and poor appearance of the product. It has a simple structure and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to facilitate the understanding of those skilled in the art, the following embodiments and accompanying drawings are provided. Figure 1-4 To further illustrate the present invention, the contents mentioned in the implementation manner are not intended to limit the present invention.

[0016] See Figure 1-4 A dust suction structure of a laser cutting device includes a laser 1 and a material tray 2 arranged below the laser 1, and also includes a moving module 3 for driving the material tray 2 to move forward, backward, left and right, a dust suction module 4 arranged below the material tray 2, and a driving mechanism 5 for driving the dust suction module 4 to move up and down. The material tray 2 is distributed with a plurality of cutting areas 21 in a rectangular array, and each cutting area 21 has a plurality of product units 22 to be cut placed in a rectangular array. One of the cutting areas 21 is located between the laser 1 and the dust suction module 4. The dust suction module 4 includes a suction nozzle 41 and a dust suction mechanism. The suction nozzle 41 is provided with a dust suction groove 411 corresponding to the position of each product unit 22 in one of the cutting areas 21. The dust suction mechanism is connected to the bottom of each dust suction groove 411 through a dust suction pipe 42.

[0017] Laser 1 emits laser light, serving as the power source for cutting. Tray 2 holds the product and must be customized based on the product's size and shape. Mobile module 3 moves the product. Because the laser's single cut range is limited, multiple cuts are required for each product, requiring multiple moves. Vacuum module 4 can be raised and lowered to prevent tray 2 from impacting the product during movement. Suction nozzle 41 is used to absorb the product and remove dust.

[0018] A product has 60*33 product units 22, and the single cutting area 21 is 5*3. The cutting position is moved by the mobile module 3 until all product units 22 are cut. The suction nozzle 41 absorbs 5*3 product units 22 at a time. After adsorption, it can ensure that the product units 22 are on the same plane, which can better guarantee the cutting yield. When in use, the product is first loaded on the tray 2. The mobile module 3 moves the tray 2 to the first 5x3 cutting area 21. The suction nozzle 41 inhales and rises to absorb the product. The laser starts cutting. When the mobile module 3 needs to move the tray 2 to the next cutting area 21, the drive mechanism 5 drives the suction nozzle 41 to move down. Repeat the above steps until the entire product 60*33 product units 22 are completely cut.

[0019] The dust suction structure of the laser cutting device of the present invention can absorb and flatten the product, providing a condition for convenient laser cutting; it can be close to the cutting position and adopt a matching dust suction groove 411 to remove smoke and dust in time to avoid poor product appearance; the waste after cutting is sucked away through the dust suction pipe 42, which can prevent the product from being deformed due to the waste.

[0020] In this embodiment, a support block 412 for supporting waste is fixed in each dust suction groove 411. The support block 412 can support the waste, and when the connection on one side is cut off, it prevents the waste from bending at the other connection due to gravity, resulting in defective products.

[0021] In this embodiment, the plurality of dust collecting grooves 411 arranged in a longitudinal direction are connected as a whole. The above structure is easy to process and convenient to use.

[0022] In this embodiment, each of the dust suction grooves 411 is provided with notches 413 on both sides. When cutting, the smoke and dust generated can be immediately extracted through the notches 413 to prevent the smoke and dust from remaining and contaminating the product.

[0023] The movable module 3 and the driving mechanism 5 used in this embodiment are both existing technologies in this field, such as using a cylinder combined with a slide rail and a slider to realize the forward and backward movement and left and right movement of the material tray 2 and the up and down movement of the suction nozzle 41. This is not an improvement point of the present invention and will not be repeated here.

[0024] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the scope of protection of the present invention.
