Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, and more specifically, to a laser cutting machine with an exchange platform. Background Technology

[0002] Laser cutting technology, as an advanced processing method, has been widely used in the processing of metal and non-metal materials due to its high precision, high efficiency, good flexibility, and excellent cutting quality. Traditional laser cutting equipment is usually equipped with a single working platform. Its workflow is as follows: while the equipment is cutting the current sheet material, the operator needs to prepare the loading and unloading of the next sheet material to be processed outside the equipment. After the current cutting operation is completed, the equipment stops running, and the operator then removes the cut sheet material along with the working platform, pushes the prepared new sheet material along with the working platform into the equipment, and finally restarts the equipment for the next round of cutting.

[0003] However, this single-work platform mode has obvious efficiency bottlenecks. The loading and unloading process and the cutting process cannot be carried out synchronously. The equipment must stop cutting to wait for the platform to be exchanged and the workpiece to be re-clamped and positioned, resulting in a lot of idle waiting time for the equipment. This non-processing time is particularly significant when processing large batches of small workpieces, which seriously restricts the improvement of overall production efficiency and the expansion of production capacity.

[0004] Based on this, this utility model discloses a laser cutting machine with an exchange platform. Summary of the Invention

[0038] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0039] Therefore, this utility model provides an exchange platform laser cutting machine, see [link / reference]. Figures 1 to 8As shown, it includes a frame A1, with a frame B2 at one end of the frame A1. Limiting blocks 3 are fixedly connected to both sides of the upper end of the frame B2. Guide rails A4 are fixedly connected to the upper parts of both sides of the inner cavity of the frame A1, and guide rails B5 are fixedly connected to the lower parts of both sides of the inner cavity of the frame B2. A support frame A6 is provided between opposite sides of each guide rail A4, and a support frame B601 is provided between opposite sides of each guide rail B5. Grooved wheels 7 are hinged to the four corners of the surfaces of each support frame A6 and support frame B601. The four grooves on the support frame A6 are slidably connected to the guide rails A4, and the four grooved wheels 7 on the support frame B601 are slidably connected to the guide rails B5. The frame A1 is connected to two sides of the other end, with drive motors A8 fixedly connected to each side. Each drive motor A8 has a reducer 9 fixedly connected to its output shaft, and each reducer 9 has a sprocket A10 fixedly connected to its output shaft. Sprockets B11 are movably connected to both sides of one end of the inner cavity of the frame A1 via a rotating pair. The same chain 12 is fitted on the surface of each sprocket A10 and sprocket B11. The support frame A6 is fixedly connected to the upper part of each chain 12, and the support frame B601 is fixedly connected to the lower part of each chain 12. A cutting assembly 13 is provided at the other end of the upper part of the frame A1, and a collecting assembly 14 is provided in the inner cavity of the frame A1.

[0040] During operation, the drive motor A8 starts, and the power is reduced and amplified by the reducer 9 before being transmitted to the sprocket A10, which drives the chain 12 to move. Since the two support frames A6 and B601 are fixed on the upper and lower sides of the chain 12 respectively, the cyclical movement of the chain 12 will drive the support frame A6, located on the guide rail A4 of frame A1, to move to the guide rail B5 of frame B2, and at the same time move the support frame B601, located on the guide rail B5 of frame B2, to the guide rail A4 of frame A1, completing the workstation exchange. The grooved wheel 7 ensures smooth movement, and the limit block 3 ensures accurate stopping position. When the support frame A6 is cutting in the processing area of ​​frame A1, the operator can safely unload and load the support frame B601 in the loading and unloading area of ​​frame B2. After the cutting is completed, the controller 15 triggers the exchange program, and the support frames A6 and B601 quickly exchange positions, so that the equipment can immediately cut new materials and realize continuous production.

[0041] Further, see Figures 1 to 12 As shown, the cutting assembly 13 includes a fixing frame 131, which is disposed on the upper part of the frame A1. A reduction motor A132 is fixedly connected to both sides of the fixing frame 131. The output shaft of each reduction motor A132 passes through the fixing frame 131. A gear A133 is fixedly connected to the output shaft of each reduction motor A132. A rack A134 is fixedly connected to both sides of the inner cavity of the frame A1 near the gear A133. Each gear A133 meshes with the rack A134.

[0042] Slider A135 is fixedly connected to both ends of the lower part of the fixed frame 131. Tracks A136 are fixedly connected to both sides of the inner cavity of the frame A1 at positions corresponding to slider A135. Each track A136 is slidably connected to slider A135. Track B137 is fixedly connected to the upper part of the other end of the fixed frame 131. Slider B138 is slidably connected to the upper part of track B137. Support plate 139 is fixedly connected to the upper part of slider B138.

[0043] A geared motor B1310 is fixedly connected to the upper part of the support plate 139. The output shaft of the geared motor B1310 passes through the support plate 139. A gear B1311 is fixedly connected to the output shaft of the geared motor B1310. A rack B1312 is fixedly connected to the other end of the support plate 139 near the gear B1311. The gear B1311 and the rack B1312 mesh with each other.

[0044] Tracks C1313 are fixedly connected to both sides of the other end of the support plate 139. Slider C1314 is slidably connected to the other end of each track C1313. Positioning plate 1315 is fixedly connected to the other end of each slider C1314. Laser cutting head 1316 is fixedly connected to the lower part of the other end of the positioning plate 1315. Gear motor C1317 is fixedly connected to the other end of the upper part of the support plate 139. Lead screw 1318 is fixedly connected to the output shaft of gear motor C1317. The lower part of lead screw 1318 is rotatably connected to support plate 139 through a rotating joint. Nut 1319 is threadedly connected to the surface of lead screw 1318. Nut 1319 is rotatably connected to positioning plate 1315.

[0045] During operation, the cutting assembly 13 drives the laser cutting head 1316 to perform three-dimensional motion. The geared motor A132 drives the gear A133 to rotate, meshing with the fixed rack A134, which in turn moves the entire fixed frame 131 along the X-axis. The track A136 and the slider A135 provide guidance and limit positioning. The geared motor B1310 drives the gear B1311 to rotate, meshing with the fixed rack B1312, which in turn moves the support plate 139 and its components along the Y-axis. The geared motor C1317 drives the lead screw 1318 to rotate, which is converted into linear motion through the nut 1319, causing the positioning plate 1315 and the laser cutting head 1316 to rise and fall along the Z-axis to adapt to different thicknesses of plates or focusing requirements.

[0046] Among them, see Figures 1 to 4 As shown, the collection assembly 14 includes multiple collection boxes 141, each collection box 141 is provided with an inner cavity of the frame A1, and rollers 142 are hinged to the four corners of the lower part of the collection box 141. Each roller 142 is slidably connected to the inner cavity of the frame A1, and a pull rod 143 is fixedly connected to one side of the collection box 141.

[0047] During operation, the collection component 14 is used to collect cutting waste. The chips and small waste generated during cutting fall into the collection box 141 in the inner cavity of the lower frame A1 through the gaps on the support frame. Periodically or when needed, the operator can easily pull out the collection box 141 via the pull rod 143 and rollers 142, empty the waste, and then push it back to its original position. Maintenance is simple. The collection box 141 continuously receives waste, keeps the inside of the equipment clean, and prevents waste accumulation from affecting the normal operation of the equipment.

[0048] In summary, this utility model solves the problem of equipment idle time through a dual-station exchange platform design, ensures smooth and accurate exchange through chain synchronous drive and grooved wheel guide rail, guarantees processing quality through a three-axis linkage cutting system, and solves the problem of waste disposal through a simple collection component, thereby effectively solving existing technical problems.
