Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a conveying device and a laser cutting device for laser cutting equipment. Background Technology

[0002] Laser cutting equipment is a machine that uses a high-power laser beam to cut, engrave, or mark materials. Due to its precision, efficiency, and high level of automation, laser cutting is widely used in manufacturing, automotive, aerospace, electronics, electrical appliances, and handicrafts, among other fields. Laser cutting equipment offers advantages such as high precision, high speed, high flexibility, and non-contact processing. It plays a crucial role in industrial automation and enjoys broad market demand and application prospects. Conventional laser cutting equipment uses a conveyor system to move the workpiece, while the laser cutting head cuts the material.

[0003] Chinese patent CN202122836030.4 discloses a flexible adjustable tracked precision laser cutting machine, including a machine base. Slide rails are provided on the upper ends of both sides of the machine base, and an X-axis drive mechanism is connected to the surface of the slide rails. A crossbeam is mounted on the upper end of the X-axis drive mechanism. In this invention, by setting tracked dog teeth on the surface of the machine base, in conjunction with a servo motor, reducer, and conveyor chain, the tracked dog teeth can be driven to rotate, allowing the workpiece to move on the machine base, facilitating the cutting of large workpieces. Simultaneously, the loading platform and ball bearings at the end provide auxiliary workpiece loading, making loading more time-saving and labor-saving. By setting slide rails on both sides of the machine base, in conjunction with the X-axis drive mechanism, the laser cutting head can move arbitrarily along the X-axis. Simultaneously, the crossbeam connected to the upper end of the X-axis drive mechanism, in conjunction with the Y-axis drive mechanism, allows the laser cutting head to move arbitrarily along the Y-axis, thus allowing flexible adjustment of the laser cutting head's position. The conveying structure in this solution lacks a cutting slit structure and needs improvement.

[0004] This invention overcomes the shortcomings of the prior art and provides a conveying device and a laser cutting device for laser cutting equipment. The conveying device has a slit and the slit position is adjustable. Utility Model Content

[0034] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figure 1-4 The diagram shown is a schematic representation of an embodiment of the conveying device for laser cutting equipment provided by this utility model.

[0036] Please refer to Figure 1-4 This embodiment is used to realize the conveying of workpieces in laser cutting equipment. It includes a frame 100, which is provided with multiple conveyor belt units 200. The multiple conveyor belt units 200 are connected end to end in sequence, and there is a gap between adjacent conveyor belt units 200.

[0037] The conveyor belt unit 200 includes a telescopic support 210, a conveyor belt 220, a power assembly 230, a tensioning assembly 240, and a first support roller 250. The telescopic support 210 is mounted on the frame 100, and the first support rollers 250 are respectively mounted at both ends of the telescopic support 210. The telescopic support 210 drives the first support rollers 250 at both ends to move closer or further apart, or the telescopic support 210 drives the first support roller 250 at one end to move closer or further away from the first support roller 250 at the other end.

[0038] The conveyor belt 220 surrounds the first support rollers 250 at both ends of the telescopic bracket 210, and the power unit 230 drives the conveyor belt 220 to move around the first support rollers 250.

[0039] The tensioning component 240 is located on the frame 100. The tensioning component 240 acts on the conveyor belt 220 to keep the conveyor belt 220 taut when conveying the workpiece. The tensioning component 240 is used to correct the deviation of the conveyor belt 220.

[0040] The telescopic support 210 changes the length of the conveying section by changing the distance between the first support rollers 250 at both ends. At the same time, the adjustment of the distance between the first support rollers 250 between adjacent conveyor belts 200 can change the width and position of the slit.

[0041] In one embodiment, the upper side of the telescopic support 210 is the conveying section of the conveyor belt 220, and the lower side of the telescopic support 210 is the buffer section of the conveyor belt 220. The conveyor belt 220 surrounds the conveying section and the buffer section. The tensioning component 240 and the power component 230 are located below the telescopic support 210, and the tensioning component 240 and the power component 230 act on the conveyor belt 220 in the buffer section.

[0042] The conveyor belt 220 in the conveying section is used for conveying workpieces, and the conveyor belt 220 in the buffer section is used for buffering the conveyor belt 220. The conveyor belt 220 is folded and wound in an S-shape in the buffer section.

[0043] In one embodiment, the tensioning assembly 240 includes a movable roller 241, a guide rail 242, a connecting plate 243, and a first motor 244. The first motor 244 is mounted on the frame 100, and its output end is connected to the connecting plate 243. The connecting plate 243 is equipped with the movable roller 241, which winds the conveyor belt 220 located in the buffer zone. The connecting plate 243 is slidably connected to the guide rail 242. The first motor 244 drives the conveyor belt 220 wound by the movable roller 241 to move along the direction of the guide rail 242.

[0044] When the conveyor belt 220 in the conveying section becomes shorter, the conveyor belt 220 in the buffer section becomes longer. The length of the conveyor belt in the buffer zone changes by an equal amount according to the length of the conveyor belt in the conveying section. At this time, the first motor 244 drives the moving roller 241 to move and pull the conveyor belt 220 to make it taut, keeping the conveyor belt 220 in a taut state.

[0045] In one embodiment, the first and last ends of the moving roller 241 are respectively provided with guide rail 242, connecting plate 243 and first motor 244. The guide rail 242 is symmetrically arranged on both sides of the conveyor belt 220. The first and last ends of the moving roller 241 are slidably connected to the guide rail 242 through the connecting plate 243. The two first motors 244 control the movement of the first and last ends of the moving roller 241 respectively.

[0046] By controlling the movement of both ends of the moving roller 241 by the first motor 244, the moving roller 241 can be oscillated, thereby correcting the deviation of the conveyor belt 220.

[0047] In one embodiment, the power assembly 230 includes a support 231, a second motor 232, a drive roller 233, and a buffer roller 234. The support 231 is disposed on the frame 100, the second motor 232 and the buffer roller 234 are disposed on the support 231, and the second motor 232 is connected to the drive roller 233 for transmission, thereby driving the drive roller 233 to rotate.

[0048] The active roller 233 and the buffer roller 234 are arranged in parallel. The height of the active roller 233 is higher than that of the buffer roller 234. The buffer roller 234 and the moving roller 241 are arranged in parallel. The buffer roller 234 and the moving roller 241 are at the same height. The active roller 233 is located between the buffer roller 234 and the moving roller 241.

[0049] The conveyor belt 220 extends from below the buffer roller 234 in the conveying section to below the moving roller 241. Below the moving roller 241, the conveyor belt 220 extends above the moving roller 241, and continues to below the drive roller 233, then above the drive roller 233, and continues into the conveying section. The conveyor belt 220 is wound in an S-shape between the moving roller 241 and the buffer roller 234.

[0050] The second motor 232 drives the drive roller 233 to rotate, which in turn drives the wound conveyor belt 220 to move between the buffer 234, the moving roller 241, and the first support roller 250. The first motor 244 drives the moving roller 241 to move along the guide rail 242, thereby moving closer to or away from the buffer roller 234, thus changing the length of the conveyor belt between the moving roller 241 and the buffer roller 234 to adapt to the length changes of the conveyor belt 220 in the conveying section, so that the conveyor belt 220 always remains taut.

[0051] In one embodiment, the telescopic support 210 has first support rollers 250 on its upper and lower sides, respectively, with the upper and lower first support rollers 250 arranged in parallel. The first support rollers 250 on the upper and lower sides are respectively provided to accommodate the telescopic support 210 with a certain thickness, ensuring that the conveyor belt 220 moves smoothly.

[0052] In one embodiment, a support roller assembly 260 is provided in the buffer zone. The support roller assembly 260 includes two second support rollers 261, which are arranged parallel to each other between the telescopic bracket 210 and the power assembly 230. The two second support rollers 261 are located at different heights and are separated by a predetermined width. The upper second support roller 261 is fixedly connected to the lower center of the telescopic bracket 210 and moves with the telescopic bracket 210. The lower second support roller 261 is fixedly connected to the frame 100. As shown in the figure, the conveyor belt 220 is wound around the second support rollers 261 in an S-shape. The support roller assembly 260 further increases the buffer length of the conveyor belt 220 in the buffer zone.

[0053] In one embodiment, the conveyor belt unit 200 includes a first conveyor belt unit 270 and a second conveyor belt unit 280. The first conveyor belt unit 270 includes one support roller group 260. The second conveyor belt unit 280 includes two support roller groups 260, which are respectively located at both ends below the telescopic bracket 210. One end of the telescopic bracket 210 of the first conveyor belt unit 270 is fixed to the frame 100, and the other end is telescopically movable. Both ends of the telescopic bracket 210 of the second conveyor belt unit 280 are telescopically movable.

[0054] In one embodiment, there are three conveyor belt units 200, namely two first conveyor belt units 270 and one second conveyor belt unit 280, with the second conveyor belt unit 280 located between the two first conveyor belt units 270.

[0055] like Figure 5-6 The diagram shown is a schematic representation of an embodiment of a laser cutting device.

[0056] Please refer to Figure 5-6 This embodiment includes the above-described conveying device embodiment for laser cutting equipment, and also includes a laser cutting component 300, which is disposed on the frame 100 and located in the interval between adjacent conveyor belt units 200.

[0057] In summary, the conveying device provided by this utility model consists of multiple conveyor belt units. The conveyor belt units adjust the conveying length supported by the telescopic bracket, thereby adjusting the conveying interval length and conveying position of the conveyor belt. The power component drives the conveyor belt to rotate around the telescopic bracket and the first support roller. The tensioning component is used to tension the conveyor belt when adjusting the conveying interval. Multiple conveyor belt units can move independently, which facilitates the adjustment of the width between adjacent conveyor belts, facilitates the falling of waste materials after cutting, and makes the adjustment of the slit position more flexible.

[0058] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
