Description

Technical Field

[0001] The present invention relates to the technical field of furniture production and processing, and specifically to a laser cutting machine for furniture production and processing. Background Art

[0002] The laser cutting machine for furniture production and processing integrates advanced laser technology, precise mechanical systems, and intelligent control systems, and can achieve cutting and processing of various furniture materials such as wood, metal, and plastic; it has high cutting precision, high speed, good edge quality, simple operation, and high automation degree, and is an indispensable high-efficiency processing equipment in the furniture manufacturing industry;

[0003] In the existing furniture processing process, it is necessary to cut wooden boards into irregular shapes by laser. Due to the different densities of each part of the wooden board, the laser is prone to cause excessive softening or even burning when passing through the local area. These softened parts may adhere to the support base after cooling, affecting the efficiency of laser cutting the wooden board; at the same time, during the process of laser cutting the wooden board, due to the small volume of the generated debris, it is easier to adhere to the rough parts of the wooden board surface, and it is difficult to efficiently clean the debris by the existing dust suction method, affecting the subsequent processing of the wooden board. Summary of the Invention

[0004] The technical problems solved by this solution are as follows:

[0005] (1) How to solve the problem that the volume of the debris generated by laser cutting the wooden board is small, it is easy to adhere to the rough parts of the wooden board surface, and it is difficult to efficiently clean the debris by the existing dust suction method, affecting the subsequent processing of the wooden board;

[0006] (2) How to solve the problem that due to the different densities of each part of the wooden board, the laser is prone to cause excessive softening or even burning when passing through the local area, and these softened parts may adhere to the support base after cooling, affecting the efficiency of laser cutting the wooden board.

[0007] The object of the present invention can be achieved by the following technical solutions: A laser cutting machine for furniture production and processing includes a workbench and a shielding cover fixedly installed on its top. A vibration mechanism for cleaning debris is arranged in the middle of the top surface of the workbench. Positioning mechanisms for fixing the wooden board are arranged on both sides of the vibration mechanism. A support plate is also fixedly installed at the bottom of the workbench;

[0008] The vibration mechanism includes a support base for placing the wooden board. Guide rods are fixedly installed at the four corners of the bottom of the support base. The bottom ends of the guide rods movably penetrate through the workbench. A first thrust spring is sleeved on the guide rods between the support base and the workbench.

[0009] A further technical improvement of the present invention lies in that: a groove is further formed in the middle of the bottom surface of the support base, square holes are formed in both side walls of the groove, the square holes are horizontally arranged, and square rods are slidably inserted into the square holes. One end of each square rod contacts the inner wall of the corresponding square hole through a second thrust spring, and a roller is rotatably arranged at the other end of each square rod. By controlling the telescopic reciprocating movement of the extending end of the hydraulic cylinder, during the process of the roller rolling from the inclined surface of the first trapezoidal block to the inclined surface of the second trapezoidal block, due to the thrust of the second thrust spring, the support base slowly moves downward, so that there is a gap between the wooden board and the two L-shaped pressing plates. During the process of the roller rolling from the inclined surface of the second trapezoidal block to the inclined surface of the first trapezoidal block, due to the thrust of the first thrust spring, the support base quickly moves upward, causing the wooden board to collide with the two L-shaped pressing plates, and it is easy to shake out the debris on the surface of the wooden board. By controlling the robotic arm to drive the dust suction pipe to move, it is convenient to absorb the shaken-out debris into the dust suction tooling, preventing it from affecting the subsequent processing of the wooden board.

[0010] A further technical improvement of the present invention lies in that: a longitudinally arranged hydraulic cylinder is fixedly installed on the support plate, the extending end of the hydraulic cylinder movably penetrates through the workbench, and a first trapezoidal block is fixedly installed at the extending end of the hydraulic cylinder. A second trapezoidal block is fixedly installed on the top of the first trapezoidal block, and the long bottom of the first trapezoidal block corresponds to the long bottom of the second trapezoidal block in position. The roller corresponds to the inclined surfaces of the first trapezoidal block and the second trapezoidal block in position.

[0011] A further technical improvement of the present invention lies in that: the positioning mechanism includes an L-shaped plate fixedly connected to the workbench. A horizontally arranged air cylinder is fixedly installed in the middle of the L-shaped plate, and the extending end of the air cylinder is rotatably connected to a pressing wheel, and the pressing wheel is slidably connected to the top of the L-shaped plate.

[0012] A further technical improvement of the present invention lies in that: turning rods are rotatably arranged at the bottom of the front and rear sides of the L-shaped plate, and a common fixed connection of one ends of the two turning rods is an L-shaped pressing plate, and the pressing wheel is in rolling connection with the L-shaped pressing plate.

[0013] A further technical improvement of the present invention lies in that: positioning rods are rotatably arranged at the top of the front and rear sides of the L-shaped plate, and a common fixed connection of one ends of the two positioning rods is a positioning strip, and the positioning strip is located below the L-shaped pressing plate. A dial rod is also fixedly inserted at the extending end of the air cylinder, and the positions at both ends of the dial rod respectively correspond to the positions in the middle of the positioning rods.

[0014] A further technical improvement of the present invention lies in that: positioning blocks are fixedly connected to the middle parts of the front and rear sides of the L-shaped plate, and tension springs are fixedly connected between the positioning blocks and the middle parts of the corresponding flipping rods; after the cutting of the wooden board is completed, by controlling the extension end of the cylinder to extend to the longest, the two pressing wheels respectively roll to the ends of the corresponding L-shaped pressing plates close to the wooden board, so that the dial rod drives the positioning rod to rotate, and the wooden board is centered by the two positioning strips. During this process, the two L-shaped pressing plates are used to limit and guide the wooden board, so that the wooden board moves horizontally, and the softened and cooled part of the wooden board in contact with the support base is scraped off by the wooden board itself, preventing the softened part of the wooden board from adhering to the support base after cooling and avoiding affecting the efficiency of laser cutting the wooden board.

[0015] A further technical improvement of the present invention lies in that: a dust suction tool for absorbing debris is fixedly arranged on the top of the shielding cover. The dust suction tool is a prior art, and the input end of the dust suction tool is communicated with a hose, and the input end of the hose movably penetrates into the shielding cover.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] When the present invention is in use, by controlling the telescopic reciprocating movement of the extension end of the hydraulic cylinder, during the process that the roller rolls from the inclined surface of the first trapezoidal block to the inclined surface of the second trapezoidal block, due to the thrust of the second thrust spring, the support base moves downward slowly, so that there is a gap between the wooden board and the two L-shaped pressing plates. During the process that the roller rolls from the inclined surface of the second trapezoidal block to the inclined surface of the first trapezoidal block, due to the thrust of the first thrust spring, the support base moves upward rapidly, so that the wooden board collides with the two L-shaped pressing plates, and the debris on the surface of the wooden board is easily shaken out. By controlling the robotic arm to drive the dust suction pipe to move, it is convenient to absorb the shaken-out debris into the dust suction tool, preventing it from affecting the subsequent processing of the wooden board.

[0018] When the present invention is in use, by controlling the extension end of the cylinder to extend to the longest, the two pressing wheels respectively roll to the ends of the corresponding L-shaped pressing plates close to the wooden board, so that the dial rod drives the positioning rod to rotate, and the wooden board is centered by the two positioning strips. During this process, the two L-shaped pressing plates are used to limit and guide the wooden board, so that the wooden board moves horizontally, and the softened and cooled part of the wooden board in contact with the support base is scraped off by the wooden board itself, preventing the softened part of the wooden board from adhering to the support base after cooling and avoiding affecting the efficiency of laser cutting the wooden board.

During this process, the two L-shaped pressing plates 903 are used to limit and guide the wooden board, so that the wooden board moves horizontally, and the softened and cooled part of the wooden board in contact with the support seat 803 is scraped off by the wooden board itself, preventing the softened part of the wooden board from adhering to the support seat 803 after cooling and avoiding affecting the efficiency of laser cutting the wooden board.

[0036] Please refer to Figure 1 and Figure 2 As shown, a dust suction tooling 5 for absorbing debris is fixedly arranged on the top of the above-mentioned shielding cover 4.

[0041] Working principle: When the present invention is in use, first, open the two opening and closing doors 1, place the wooden board on the support seat 803, and then close the two opening and closing doors 1. At this time, the extending end of the cylinder 906 is at the shortest length, which is convenient for manual placement of the wooden board, and the extending end of the hydraulic cylinder 805 is at the longest length to provide support for the support seat 803; control the extending end of the cylinder 906 to extend to half of its length, so that the pressing wheels provide rolling pressing on the L-shaped pressing plate 903. When the two pressing wheels respectively roll to the middle parts of the corresponding L-shaped pressing plates 903, press the two ends of the wooden board through the two L-shaped pressing plates 903, and cut the wooden board through the laser cutting tooling 10; after the cutting of the wooden board is completed, control the extending end of the cylinder 906 to extend to the longest length, and the two pressing wheels respectively roll to the ends of the corresponding L-shaped pressing plates 903 close to the wooden board, so that the lever 908 drives the positioning rod 901 to rotate, and center the wooden board through the two positioning strips 902.

During the process of the roller 807 rolling from the inclined surface of the first trapezoidal block 802 to the inclined surface of the second trapezoidal block 806, due to the thrust of the second thrust spring 809, the support seat 803 slowly moves downward, so that there is a gap between the wooden board and the two L-shaped pressing plates 903. During the process of the roller 807 rolling from the inclined surface of the second trapezoidal block 806 to the inclined surface of the first trapezoidal block 802, due to the thrust of the first thrust spring, the support seat 803 quickly moves upward, causing the wooden board to collide with the two L-shaped pressing plates 903, and easily shaking out the debris on the surface of the wooden board. Control the robotic arm 12 to drive the dust suction pipe to move, so that it can absorb the shaken-out debris into the dust suction tooling 5, preventing it from affecting the subsequent processing of the wooden board.
