Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a numerically controlled laser cutting device capable of partitioned cutting. Background Art

[0002] Sheet metal processing has a wide range of applications, and it appears in almost all walks of life. With the widespread application of laser cutting machines in sheet metal processing, it will become the mainstream in this field. At the same time, with the increase in the types of sheet metal processing products, the requirements for sheet metal formats will increase. Among them, large-format laser cutting is a type of sheet metal processing that is being promoted and applied. Now, two types of processing formats, 6 meters and 8 meters, have been successfully applied.

[0003] The sheet metal processing process mainly includes loading, processing and unloading. In order to improve efficiency, multiple processing tables are set up, that is, multiple processing areas are divided and cut in turn, which is the most common design idea. That is, while the first processing table is processing, the second table is loaded and unloaded to make full use of the processing waiting time.

[0004] However, the current loading and unloading method is to manually load and unload the second table while the first processing table is processing. The manual operation requires the manual operation to remove the cut sheet metal parts on the table before placing new sheet metal parts. In this way, the manual operation needs to stay at the laser cutting machine for a long time. The laser cutting machine is a dangerous equipment. The manual operation will inevitably increase the risk of manual injury if the manual operation is in contact with it for a long time. At the same time, the manual operation at the laser cutting machine for a long time will also easily affect the operation of the equipment. Summary of the invention

[0037] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0040] See also Figure 1 As shown, a CNC laser cutting device capable of partitioned cutting is provided, comprising a machine tool 100, and a driving mechanism 101 and a laser cutting head 102 located above the machine tool 100. The driving mechanism 101 has an X-axis driving unit, a Y-axis driving unit, and a Z-axis driving unit; wherein the X-axis driving unit is arranged at both ends of the top of the machine tool 100, the Y-axis driving unit is arranged above the X-axis driving unit, the Z-axis driving unit is arranged above the Y-axis driving unit, and the laser cutting head 102 is connected to the Z-axis driving unit. In this way, through the drive of the X-axis driving unit, the Y-axis driving unit, and the Z-axis driving unit, the laser cutting head 102 can move in the X, Y, and Z-axis directions, thereby cutting the sheet metal parts.

[0041] like Figure 2As shown, a carrier platform 110 is disposed on the top of the machine tool 100, and a plurality of workpiece carrier plates 120 are rotatably disposed on the top of the carrier platform 110, and the plurality of workpiece carrier plates 120 form a plurality of processing areas on the top of the carrier platform 110, so that a plurality of sheet metal parts can be cut in sequence; and a locking member 130 is also connected to the end of the workpiece carrier plate 120, and the locking member 130 is used to fix the workpiece carrier plate 120 on the surface of the carrier platform 110 when the surface of the workpiece carrier plate 120 and the surface of the carrier platform 110 are in the same plane; the locking member 130 is also connected to a sensing drive component 140, which is used to sense the position of the laser cutting head 102. When the laser cutting head 102 processes the sheet metal on the next workpiece carrier plate 120, the sensing drive component 140 drives the locking component 130 to disengage from the previous workpiece carrier plate 120, so that the sheet metal after cutting can press the workpiece carrier plate 120 to rotate downward under its own gravity, and slide off the surface of the workpiece carrier plate 120 during the rotation of the workpiece carrier plate 120, thereby completing the automatic unloading of the sheet metal.

[0042] That is to say, by sensing the cutting position of the laser cutting head 102, when the laser cutting head 102 cuts the next sheet metal part, the workpiece carrier plate 120 located under the previous sheet metal part can deliver the cut sheet metal part by rotating, thereby avoiding the operation of manual unloading, reducing the time that humans stay at the laser cutting machine, improving the efficiency of loading and unloading, and reducing the chance of manual injury.

[0043] like Figure 2 As shown in the above, a plurality of rotation grooves 111 for accommodating the workpiece carrier plate 120 and a plurality of installation grooves 112 for accommodating the locking member 130 are opened on the top of the carrier platform 110 , and the installation grooves 112 are communicated with the rotation grooves 111 .

[0044] like Figure 3 As shown, in some embodiments, a rotating shaft 121 is fixedly provided on both sides of one end of the workpiece carrier plate 120, and the rotating shaft 121 penetrates both sides of the rotating groove 111 in a rotating manner. In addition, a torsion spring 122 may be sleeved on the outer ring of the rotating shaft 121, and one end of the torsion spring 122 is fixedly connected to the side wall of the workpiece carrier plate 120, and the other end is fixedly connected to the side wall of the rotating groove 111. In this way, when the workpiece carrier plate 120 rotates downward, the workpiece carrier plate 120 will drive the torsion spring 122 to twist and deform, so that when the sheet metal part is separated from the surface of the workpiece carrier plate 120, the torsion spring 122 drives the workpiece carrier plate 120 to reset through elasticity.

[0045] The locking member 130 cooperates with the workpiece carrier plate 120. Figure 4As shown, in some embodiments, the locking member 130 includes a box body 131 fixedly arranged in the mounting groove 112, the end of the box body 131 facing the workpiece supporting plate 120 is an open structure, a straight plate 132 is slidably arranged in the box body 131, a return spring 133 is arranged between one end of the straight plate 132 and the inner end of the box body 131 to elastically connect the two, an inclined surface 134 is provided at the bottom of the end of the straight plate 132 facing the workpiece supporting plate 120, and a clamping plate 123 is fixedly connected to the end of the workpiece supporting plate 120 facing the straight plate 132.

[0046] In addition, Figure 4 In the embodiment, a transmission part is provided between the inductive driving part 140 and the locking part 130 , and the transmission part is a fixing rod 135 fixedly connected to the straight plate 132 .

[0047] like Figure 5 As shown, in some embodiments, the fixing rod 135 is fixedly arranged below the straight plate 132, and an empty groove is opened at the bottom of the box body 131 for the fixing rod 135 to slide. The bottom end of the fixing rod 135 is fixedly connected to an inclined plate 136, and the bottom end of the inclined plate 136 is inclined toward one side of the workpiece supporting plate 120; the inductive driving member 140 includes a fixing column 141 fixedly arranged at the bottom of the supporting platform 110, and a waste loading plate 142 located below the supporting platform 110, the fixing column 141 slides through the waste loading plate 142, and a compression spring 143 is arranged between the bottom end of the fixing column 141 and the bottom of the waste loading plate 142 to elastically connect the two, and a driven rod 144 is fixedly connected to the side wall of the waste loading plate 142, and one end of the driven rod 144 extends toward another mounting groove 112, and is located above the inclined plate 136 after the extension, so as to push the inclined plate 136 through the driven rod 144 when the waste presses the waste loading plate 142 to move downward. In addition, a material guide plate 145 is fixedly disposed at the bottom of the workpiece carrier plate 120 . The material guide plate 145 is arranged at an angle to guide the waste materials dropped from the top of the workpiece carrier plate 120 to the waste loading plate 142 .

[0048] Working principle:

[0049] Put multiple sheet metal parts on top of the corresponding workpiece carrier plate 120, and then control the laser cutting head 102 to cut the subsequent sheet metal parts in sequence starting from the first sheet metal part. When the cutting of the first sheet metal part is completed, the laser cutting head 102 is cutting the second sheet metal part. The waste cut from the second sheet metal part falls on the surface of the guide plate 145 through the workpiece carrier plate 120, and then slides onto the waste loading plate 142 due to the inclination of the guide plate 145. As the waste on the surface of the waste loading plate 142 gradually increases, the compression spring 143 begins to be compressed, thereby forcing the waste loading plate 142 to move downward. The downward movement of the waste loading plate 142 drives the driven rod 144, and the driven rod 144 The straight plate 132 is displaced by the fixing rod 135 by pressing the inclined plate 136 with one end thereof, so that the straight plate 132 is separated from the bottom of the clamping plate 123. At this time, the straight plate 132 no longer supports the clamping plate 123, so that under the pressure of the sheet metal, the first workpiece supporting plate 120 starts to drive the cut sheet metal to rotate, and during the rotation process, the sheet metal on the top of the first workpiece supporting plate 120 starts to slide down, thereby separating from the first workpiece supporting plate 120.

[0050] Then, when the sheet metal part is separated from the workpiece carrier plate 120, the gravity on the workpiece carrier plate 120 becomes lower, and the torsion spring 122 drives the workpiece carrier plate 120 to reset by its own elasticity. During the reverse rotation and reset process of the workpiece carrier plate 120, the clamping plate 123 pushes the straight plate 132 toward the inner end of the box body 131 through the inclined surface 134, so that the clamping plate 123 is on the top of the straight plate 132. Finally, a new sheet metal part can be placed on the top of the workpiece carrier plate 120.

[0051] In addition, the induction drive member 140 performs a blanking operation on the first cut sheet metal part when the second sheet metal part is being cut, which will result in the last sheet metal part being unable to be automatically blanked. Figure 6 As shown:

[0052] In other embodiments, the fixing rod 135 is fixedly arranged above the straight plate 132, and an empty groove for the fixing rod 135 to slide is opened on the top of the box body 131, and the top of the fixing rod 135 is fixedly connected to the guide plate 150, and one side of the guide plate 150 is an arc-shaped structure; the inductive driving component 140 includes a longitudinally arranged sleeve 151, and a sliding rod 152 is longitudinally slidably arranged in the sleeve 151, and a connecting spring 153 is arranged between the top of the sliding rod 152 and the inner end of the sleeve 151 to elastically connect the two, and a wedge block 154 is fixedly arranged on the side of the sliding rod 152 opposite to the guide plate 150, and the sleeve 151 is fixedly connected to the driving mechanism 101 through the connecting arm 155. When the driving mechanism 101 is at the second workpiece supporting plate 120, the sleeve 151 is at the first workpiece supporting plate 120.

[0053] Working principle:

[0054] When the cutting of the first sheet metal is completed, the driving mechanism 101 drives the driving mechanism 101 to move to the second sheet metal. When the driving mechanism 101 moves to the second sheet metal, the sliding rod 152 contacts the arc surface of the guide plate 150, and pushes the fixing rod 135 through the arc surface of the guide plate 150, so that the fixing rod 135 drives the straight plate 132 to move away from the clamping plate 123. At this time, the straight plate 132 no longer supports the clamping plate 123, so that under the pressure of the sheet metal, the first workpiece supporting plate 120 begins to drive the cut sheet metal to rotate. During the rotation process, the sheet metal on the top of the first workpiece supporting plate 120 begins to slide down, thereby separating from the first workpiece supporting plate 120.

[0055] When performing a new round of cutting, the driving mechanism 101 needs to move to the first workpiece carrier plate 120. To this end, when the driving mechanism 101 drives the slide rod 152 to move to the first workpiece carrier plate 120, the wedge block 154 will contact the side wall of the guide plate 150, so that under the guidance of the wedge block 154, the wedge block 154 drives the slide rod 152 to move upward, so that the slide rod 152 passes over the guide plate 150, avoiding pushing the fixed rod 135 during this process.

[0056] Furthermore, one end of the guide plate 145 is bent toward the waste loading plate 142 to form a pushing end 146. The pushing end 146 is a flexible structure (such as metal, rubber, etc.), so that when the workpiece supporting plate 120 rotates, the pushing end 146 moves on the top of the waste loading plate 142 to push the waste on the top of the waste loading plate 142 off.

[0057] The specific working principle is that when the workpiece supporting plate 120 is pressed by the sheet metal to rotate downward, the sheet metal will slide toward the arrow above the workpiece supporting plate 120; and when the guide plate 145 follows the workpiece supporting plate 120 to rotate, one end of the pushing end 146 is against the top of the waste loading plate 142, and when the workpiece supporting plate 120 rotates, the pushing end 146 squeezes the waste loading plate 142, so that the pushing end 146 is deformed, and at one end of the top of the waste loading plate 142, the waste on the top of the waste loading plate 142 is pushed (the pushing direction refers to the arrow on the top of the waste loading plate 142), so that the waste on the top of the waste loading plate 142 falls off.

[0058] It can be seen that the material guide plate 145 can not only guide the waste to the waste loading plate 142, but also push the waste on the top of the waste loading plate 142 to one side of the machine tool 100 during the rotation of the workpiece supporting plate 120, thereby preventing the waste generated during the cutting process from falling directly under the machine tool 100, thereby improving the cleaning efficiency of the waste.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.

The scope of protection of the present invention is defined by the attached claims and their equivalents.
