Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and in particular to an automatic laser cutting machine and system for furniture manufacturing. Background Art

[0002] The working principle of the automatic laser cutting machine is to focus the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the melted or vaporized metal (or material). As the relative position of the beam and the workpiece moves, the material is eventually cut, thereby achieving the purpose of cutting.

[0003] Applying automated laser cutting technology to the furniture manufacturing industry can ensure that the furniture is accurate in size, has smooth edges, and improves quality. It can also perform fast cutting to improve production efficiency and shorten cycles. It can cut complex patterns to meet creative designs and create unique styles. The entire processing process is environmentally friendly and energy-saving, with less waste and no noise or dust pollution. It has strong adaptability and can cut a variety of metal sheets.

[0004] Existing laser cutting machines can only cut thinner metal sheets when cutting materials. Once the metal sheet is thicker, the laser beam power needs to be increased, which will cause the cutting surface to become rough and not smooth due to excessive energy accumulation. In addition, high-power laser cutting may cause excessive melting of the cutting surface, which may cause the entire cutting surface to melt and produce melt, thereby affecting the cutting effect and causing large defects on the cutting surface of the final processed product.

DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] In the description of the present invention, it should be understood that “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0028] See also Figures 1 to 8 The present invention provides an automated laser cutting machine and system for furniture manufacturing: comprising a processing main frame 101, a transmission platform 102, a cutting control main box 103 and a working component, wherein the working component comprises a laser cutting head 104, a fixed bracket 105, an ultrasonic thickness gauge 106, an adjustment cylinder 107 and a mounting component, wherein the mounting component comprises a connecting frame 201, a top slide 202, a lifting cylinder 203 and a bottom slide 204, wherein the mounting component further comprises a fixed rack 205, a bottom driving gear shaft 206, a top driving gear shaft 207 and a driving component, wherein the driving component comprises a driving gear 208, toothed chain 209 and drive motor 210. The above-mentioned solution solves the problem that the existing laser cutting machines can only cut thinner metal plates when cutting materials. Once the thickness of the metal plate is thicker, it is necessary to increase the laser beam power, which will cause the cutting surface to become rough and not smooth due to excessive energy accumulation. In addition, when high-power laser cutting is performed, it may cause the cutting surface to be over-melted, which may cause the entire cutting surface to melt and produce melt, thereby affecting the cutting effect and causing large defects in the cutting surface of the final processed product.

[0029] Furthermore, the processing main frame 101 is provided with three sections of the transmission table 102, the cutting control main box 103 is installed on the transmission table 102, the three laser cutting heads 104 are installed on the processing main frame 101 through the mounting component, the three laser cutting heads 104 are electrically connected to the cutting control main box 103, two of the three laser cutting heads 104 are arranged above the transmission table 102, and the other is arranged below the transmission table 102, the fixed bracket 105 is fixedly installed on the processing main frame 101, the ultrasonic thickness gauge 106 is slidably installed on the fixed bracket 105, the output end of the adjusting cylinder 107 is connected to the ultrasonic thickness gauge 106, the adjusting cylinder 107 is fixedly installed on the fixed bracket 105, and the mounting component is connected to the processing main frame 101 to complete the installation of the three laser cutting heads 104.

[0030] Specifically, the three sections of the transmission platform 102 arranged on the processing main frame 101 are the feeding section, the transition section and the discharging section in sequence. The two laser cutting heads 104 located on the top of the transmission platform 102 are respectively located between the feeding end and the transition section and between the transition section and the discharging section, while the laser cutting head 104 arranged at the bottom of the transmission platform 102 is arranged between the feeding end and the transition section. The cutting points of the two laser cutting heads 104 arranged above and below between the feeding end and the transition section are the same, so that the upper and lower surfaces of the metal plate can be pre-cut synchronously by the two laser cutting heads 104. The three laser cutting heads 104 are all controlled by the cutting control main box 103.

[0031] The ultrasonic thickness gauge 106 is slidably disposed on the fixed bracket 105, and the housing of the ultrasonic thickness gauge 106 is fixed to the output end of the adjustment cylinder 107, so that the user can drive the ultrasonic thickness gauge 106 to slide on the fixed bracket 105 through the adjustment cylinder 107, and then adjust the detection position of the ultrasonic thickness gauge 106, so as to accurately detect the thickness of the actual cutting position of the processing plate;

[0032] The ultrasonic thickness gauge 106 mainly emits ultrasonic pulses through a probe. When the ultrasonic pulses propagate inside an object, they will be reflected and scattered. After receiving the reflected and scattered waves, the receiver converts them into electrical signals, and calculates the thickness of the object by measuring the reflection and propagation time. The ultrasonic thickness measurement technology is fast, accurate, and non-destructive, and is applicable to a variety of materials. Therefore, the actual cutting thickness of the material to be cut can be detected by setting the corresponding ultrasonic thickness gauge 106;

[0033] During actual processing, the workpiece to be processed is transported by the transmission table 102 arranged on the processing main frame 101, and then the thickness of the transported workpiece is detected by the ultrasonic thickness gauge 106. The corresponding cutting plan is generated according to the detection result, which can be divided into three levels: thin, thick and thick according to the detected thickness range. When the thickness of the detected workpiece is thin, the two laser cutting heads 104 arranged between the feeding section and the transition section do not need to be pre-cut, and a single cutting can be performed directly by the laser cutting heads 104 arranged in the transition section and the discharging section. When it is detected that the thickness of the workpiece to be processed is thick, the laser cutting head 104 on the upper side between the feeding section and the transition section can be used to pre-cut the cutting surface of the workpiece in advance, and then the subsequent laser cutting head 104 can be used to perform another cutting. Cutting, when it is detected that the thickness of the workpiece is thick, the upper and lower laser cutting heads 104 arranged between the feed section and the transition section can perform pre-cutting processing on the upper and lower surfaces of the workpiece at the same time, and finally the cutting is completed by the subsequent laser cutting head 104, thereby avoiding the problem of defects on the workpiece surface due to excessive power of the laser cutting head 104 during a single cutting. In addition, the user can also set further plans according to the detailed data of the cutting material and thickness during actual operation, such as subdividing the thickness range, and adjusting the power of the laser cutting head 104 for pre-cutting and subsequent secondary cutting according to the actual detected thickness of the cut workpiece while flexibly adjusting the cutting method, so that energy waste can be avoided to a certain extent, so that the energy consumption of the entire cutting is lower while ensuring the cutting effect.
