Detailed implementation manner

[0019] Next, in combination with the attached Figure 1 - attached Figure 5 A specific embodiment of the present invention will be elaborated in detail.

[0020] Referring to the attached Figures 1 - 5 , a production and cutting device for aluminum single plates, including a cutting machine body 1, on which an electrically controlled laser cutter 11 is slidably connected, and the laser cutter 11 moves to position and cut the aluminum single plate.

[0021] As described in the background art, due to the low hardness of aluminum single plates, especially pure aluminum or low-strength alloy materials, during the handling process, if the aluminum single plate is not reinforced, it is prone to bending under concentrated stress, resulting in a reduction in cutting accuracy. Based on this, the present device is designed as follows: Two symmetrically distributed dual-axis motors 12 are installed on the cutting machine body 1, a first screw 13 is provided on the dual-axis motor 12, and a leveling assembly is connected to the first screw 13 through a sliding member 14, aiming to use the leveling assembly to reinforce and correct the aluminum single plate.

[0022] The leveling assembly includes a guiding frame 15 slidably connected to the sliding member 14, a moving frame 16 is fixedly connected to the guiding frame 15, two receiving plates 18 are slidably connected to the moving frame 16, the aluminum single plate is received by the two receiving plates 18, a positioning frame 161 is fixedly connected to the moving frame 16, an electric push rod 110 is installed on the positioning frame 161, a pressing frame 111 is provided on the output shaft of the electric push rod 110, and an extrusion roller 112 is rotatably connected to the pressing frame 111. That is, through the cooperation of the extrusion roller 112 and the two receiving plates 18, the leveling effect of the aluminum single plate is achieved.

[0023] The aluminum single plate is placed on the receiving plate 18. The electric push rod 110 acts, and the pressing frame 111 is controlled to move downward. The linkage extrusion roller 112 moves downward synchronously and contacts the aluminum single plate on the receiving plate 18, that is: the aluminum single plate is pressed between the extrusion roller 112 and the receiving plate 18. The double-shaft motor 12 is started, and the first screw rod 13 is controlled to rotate. The two sliding members 14 move forward, driving the guiding frame 15, the moving frame 16, the receiving plate 18, the positioning frame 161, the pressing frame 111 and the extrusion roller 112 to move forward, that is, the extrusion roller 112 and the receiving plate 18 move towards the center of the aluminum single plate. Subsequently, through the double-shaft motor 12, the first screw rod 13 is controlled to rotate in the reverse direction, and the two sliding members 14 move backward, driving the guiding frame 15, the moving frame 16, the receiving plate 18, the positioning frame 161, the pressing frame 111 and the extrusion roller 112 to move backward, meaning that the extrusion roller 112 and the receiving plate 18 gradually move to the edge of the aluminum single plate. Under the extrusion action of the extrusion roller 112 and the receiving plate 18, the aluminum single plate is fixed and straightened, and the bent part is leveled.

[0024] Subsequently, the laser cutter 11 acts, moves to the target area, and cuts the leveled aluminum single plate.

[0025] In the above leveling action, the receiving plate 18 is slidably connected to the moving frame 16. The purpose is to adjust the distance between the two receiving plates 18 through the sliding of the receiving plate 18 to adapt to aluminum single plates of different sizes. However, during the actual cutting process, the two receiving plates 18 should remain fixed relative to the moving frame 16 to avoid the accidental sliding of the receiving plate 18 affecting the cutting accuracy of the aluminum single plate. Therefore, one end of the receiving plate 18 is connected to the moving frame 16 by a bolt 19. When the bolt 19 is tightened, the receiving plate 18 can freely slide on the moving frame 16 to adjust the distance according to the size of the aluminum single plate. When the bolt 19 is loosened, the receiving plate 18 is fixed on the moving frame 16, thereby avoiding the subsequent sliding of the receiving plate 18.

[0026] Since the extrusion roller 112 is rotatably connected to the pressing frame 111, to ensure that the extrusion roller 112 cooperates with the receiving plate 18 during the backward movement of the pressing frame 111 to realize the clamping and leveling of the aluminum single plate, the extrusion roller 112 cannot rotate when moving backward. Specifically: ratchets 113 are fixedly connected to both ends of the extrusion roller 112. A support rod 116 is fixedly connected to the pressing frame 111. A ratchet pawl 114 is rotatably connected to the support rod 116. The ratchet 113 and the ratchet pawl 114 cooperate. A first torsion spring 115 is arranged between the ratchet pawl 114 and the support rod 116. The extrusion roller 112, the ratchet 113 and the ratchet pawl 114 form a one-way gear structure, that is: when the extrusion roller 112 moves forward, the ratchet 113 meshes with the ratchet pawl 114, and the extrusion roller 112 rotates freely; when the extrusion roller 112 moves backward, the ratchet pawl 114 restricts the ratchet 113, thereby restricting the free rotation of the extrusion roller 112. Thus, during the backward movement of the pressing frame 111, the extrusion roller 112 remains in a non-rotating state to cooperate with the receiving plate 18 to level the aluminum single plate.

[0027] As described above, the two sliding members 14 move towards the center of the aluminum single plate (i.e., move forward), driving the linkage guide frame 15, the moving frame 16, the receiving plate 18, the positioning frame 161, the pressing frame 111 and the pressing roller 112 to move forward. The aluminum single plate is pressed between the pressing roller 112 and the receiving plate 18. The pressing roller 112 moves forward and rotates. The pawl 114 cooperates with the ratchet wheel 113, and the ratchet wheel 113 rotates synchronously, and the first torsion spring 115 deforms.

[0028] Through the double-shaft motor 12, the two sliding members 14 move towards the edge of the aluminum single plate (i.e., move backward), driving the linkage guide frame 15, the moving frame 16, the receiving plate 18, the positioning frame 161, the pressing frame 111 and the pressing roller 112 to move backward. Due to the pawl 114 restricting the ratchet wheel 113, the pressing roller 112 moves backward without rotating. The pressing roller 112 and the receiving plate 18 gradually move to the edge of the aluminum single plate, thereby straightening and flattening the aluminum single plate. Subsequently, the laser cutter 11 is started for cutting.

[0029] The cut aluminum single plates are usually stored and transported in a flat state. To reduce the frictional scratches of the aluminum single plates during handling and stacking and lower the warehousing and transportation costs, the device winds and stores the cut aluminum single plates through a winding assembly.

[0030] The winding assembly includes a bracket 27 fixedly connected to the rear side of the moving frame 16. A servo motor 2 is provided on the bracket 27. A slide rail 17 is provided on the rear side of the moving frame 16. Two symmetrically distributed support frames 26 are slidably connected to the slide rail 17. A winding member 25 is rotatably connected between the two symmetrically distributed support frames 26. A winding groove is formed on the winding member 25 for the aluminum single plate to extend into the winding groove. The winding effect is achieved through the rotation of the winding member 25. The output shaft of the servo motor 2 is connected to the winding member 25, and the servo motor 2 is the power source for the rotation of the winding member 25.

[0031] To facilitate the aluminum single plate on the receiving plate 18 to be directed into the winding groove on the winding member 25, a guiding plate 23 is rotatably connected to the receiving plate 18. A second torsion spring 24 is provided between the guiding plate 23 and the receiving plate 18. The end of the guiding plate 23 is connected to the winding groove on the winding member 25. The purpose is that the aluminum single plate on the receiving plate 18 is guided by the guiding plate 23 and moves into the winding groove on the winding member 25.

[0032] The edges of the cut aluminum veneer are still pressed by the receiving plate 18 and the squeezing roller 112. In order to facilitate the aluminum veneer to be guided by the receiving plate 18 and the guide plate 23 and move to the winding groove on the winding member 25, the following linkage design is made: a conduction rod 22 is fixedly connected to the ratchet 113, and a belt 21 is cooperated between the conduction rod 22 and the output shaft of the servo motor 2. Based on the existence of the belt 21, the power of the servo motor 2 is transmitted to the conduction rod 22, driving the ratchet 113 and the squeezing roller 112 to rotate, and the rotation of the squeezing roller 112 provides a thrust to the aluminum veneer pressed thereunder.

[0033] After the laser cutter 11 cuts, the servo motor 2 starts to operate, and through the transmission of the belt 21, the ratchet 113 and the squeezing roller 112 rotate. The rotation of the squeezing roller 112 pushes the aluminum veneer upward, and the aluminum veneer moves to the winding groove on the winding member 25 under the guidance of the guide plate 23. As the servo motor 2 operates, the winding member 25 rotates, and the aluminum veneer is wound on the winding member 25.

[0034] The thickness of the aluminum sheet rolled up on the winding member 25 increases, and is squeezed with the guide plate 23. As the winding member 25 rotates continuously, the guide plate 23 rotates downward under pressure, and the second torsion spring 24 deforms. After the winding is completed, the winding member 25 is removed, the second torsion spring 24 is reset, and the guide plate 23 is reset accordingly, so as to facilitate the next round of use.

[0035] In order to facilitate the stacking and storage of the wound aluminum veneer, the present device moves the winding piece 25 out of the cutting machine body 1 through a transfer assembly, and a fixing frame 3 is fixedly connected to the two side walls of the cutting machine body 1, and a second screw 31 is rotatably connected to the fixing frame 3, and a first gear 32 is fixedly connected to the second screw 31. A second gear 33 is fixedly connected to the output shaft of the servo motor 2, and the first gear 32 is meshed with the second gear 33. A clamping frame 34 is threadedly connected to the second screw 31, and the clamping frame 34 and the winding piece 25 can be clamped together. The removal of the winding piece 25 can be achieved by moving the clamping frame 34.

[0036] The aluminum veneer is rolled up on the winding member 25, and the dual-axis motor 12 is started to drive the moving frame 16. The winding member 25 and the support frame 26 move toward the direction close to the transfer assembly until the positioning frame 34 clamps and receives the winding member 25. The dual-axis motor 12 is turned off, and the servo motor 2 is started. The second gear 33 rotates and engages with the first gear 32. The first gear 32 rotates, and the second screw 31 rotates under control. The positioning frame 34 moves to the left on the second screw 31. Based on the clamping of the positioning frame 34 to receive the winding member 25, the winding member 25 is linked to move to the left, and the support frame 26 moves to the left on the slide rail 17 until the support frame 26 is separated from the slide rail 17, that is, the winding member 25 is separated from the cutting machine body 1, so that the aluminum veneer on the winding member 25 can be removed and stored.

[0037] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
