Description

Technical Field

[0001] The utility model belongs to the technical field of cutting positioning, and particularly relates to a laser cutting sheet positioning device. Background Art

[0002] Laser cutting uses a focused laser beam to irradiate a sheet material, causing the sheet material to quickly melt and vaporize. At the same time, a high-speed air flow is used to blow away the molten material, thereby realizing the cutting of the workpiece. Laser cutting has high cutting efficiency and high cutting accuracy, so it is mostly used for cutting operations on sheet materials.

[0003] Currently, when cutting a sheet material, it is mostly manually placed on a conveying mechanism, and the sheet material approaches the laser cutting machine through conveying to achieve the cutting operation.

[0004] However, errors or inclinations in the position of the sheet material are likely to occur during the conveying process or due to human factors, resulting in quality problems in the cutting operation.

[0005] Therefore, in view of the deficiencies of the above-mentioned solutions in actual manufacturing and implementation, they are corrected and improved. At the same time, in the spirit of seeking excellence and with the assistance of professional knowledge and experience, and after various ingenious ideas and tests, the present utility model is created. A laser cutting sheet positioning device is provided to solve the above problems. Summary of the Utility Model

[0006] The utility model provides a laser cutting sheet positioning device, which solves the problems in the prior art.

[0007] The technical solution of the utility model is realized as follows: A laser cutting sheet positioning device includes: a plurality of conveying rollers evenly distributed at equal intervals. A first positioning mechanism for lateral movement is arranged between the conveying rollers and adjacent conveying rollers. A bracket is arranged outside the conveying rollers, and a second positioning mechanism for longitudinal movement is arranged on the bracket. A second support frame is arranged at one end of the bracket, and a laser cutting machine is slidably and cooperatively installed on the second support frame.

[0008] As a preferred embodiment of a laser cutting sheet positioning device, roller shafts are arranged at both ends of the conveying roller, and shaft seats fixed on the bracket are sleeved on the roller shafts. A double pulley is arranged at one end of the conveying roller, a synchronous belt is engaged with the double pulley, a driving motor is arranged on the bracket, and the double pulley is in transmission cooperation with the output end of the driving motor through the synchronous belt.

[0009] Adopting the above solution, the driving motor is specifically a reduction motor with a speed adjustment function to achieve better conveying of the sheet material. The reduction motor drives multiple conveying rollers to move in the same direction through transmission.

[0010] As a preferred embodiment of a laser cutting sheet positioning device, the bracket includes a right-angle plate, the right-angle plate includes a transverse plate and a longitudinal plate, a support plate is fixedly connected to the inner wall of the longitudinal plate, the shaft seat is fixed to the support plate, the bottom of the longitudinal plate is fixedly connected to the base plate, the drive motor is fixed to the base plate, the shaft seat is fixed to the support plate by fastening bolts, and the base plate is fixed to the right-angle plate by welding.

[0011] As a preferred embodiment of a laser cutting sheet positioning device, the first positioning mechanism includes a bidirectional cylinder, the output end of the bidirectional cylinder is connected to a special-shaped bent rod, there is a gap between the conveying roller and the adjacent conveying roller, the special-shaped bent rod extends upward along the gap, and a limiting ring is provided at the proximal end of the special-shaped bent rod. A pipe sleeve is slidably fitted on the special-shaped bent rod, and the limiting ring is used to limit the pipe sleeve.

[0012] With the above solution, the pressure gas source enters the bidirectional cylinder from the gas port. Under the action of pressure, the special-shaped curved rods at both ends move in both directions to facilitate the entry of the sheet. After the pressure is released, the special-shaped curved rods at both ends return to their original positions to position the sheet and straighten it.

[0013] The tube sleeve can move axially along the special-shaped curved rod, and the sheet moves along with the conveying roller, and the tube sleeve can reduce the conveying resistance.

[0014] As a preferred embodiment of a laser cutting sheet positioning device, the bidirectional cylinder is fixed on the base plate. The bidirectional cylinder is specifically an air cylinder and is fixedly matched with the base plate by fastening bolts.

[0015] As a preferred embodiment of a laser cutting sheet positioning device, the second positioning mechanism includes a first support frame, a one-way cylinder is provided on the top of the first support frame, and a pressure plate is connected to the output end of the one-way cylinder, and the pressure plate is located below the first support frame.

[0016] With the above solution, the one-way cylinder is specifically an electric cylinder, and the push rod of the electric cylinder is extended and retracted to move away from or closer to the sheet. When the pressure plate is close to the sheet, it is beneficial to the positioning of the sheet and avoids displacement during the cutting process.

[0017] As a preferred embodiment of a laser cutting sheet positioning device, the first support frame is fixed to the right-angle plate, and the first support frame is fixedly matched with the right-angle plate by welding.

[0018] As a preferred embodiment of the laser cutting sheet positioning device, the pressing plate corresponds to the conveying roller in the upper and lower parts.

When the special-shaped bent rods at both ends approach the bracket, it is conducive to the entry of the sheet. When the special-shaped bent rods at both ends move toward the center, it is conducive to positioning the sheet and aligning it.

[0021] 2. The extension and retraction of the electric cylinder push rod will drive the pressing plate to move synchronously. When the pressing plate is close to the sheet, it is beneficial to the positioning of the sheet and avoids displacement during the cutting process. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0036] As Figures 1-11 shown, a laser cutting sheet positioning device includes: a plurality of conveying rollers 1 evenly distributed at equal intervals, a first positioning mechanism 3 for horizontal movement is arranged between the conveying rollers 1 and adjacent conveying rollers 1, a bracket 2 is arranged outside the conveying rollers 1, a second positioning mechanism 4 for vertical movement is arranged on the bracket 2, a second support frame 5 is arranged at one end of the bracket 2, and a laser cutting machine 6 is slidably and cooperatively installed on the second support frame 5.

[0037] As Figure 4 、 5 、9 shown, roller shafts are arranged at both ends of the conveying roller 1, shaft seats 11 fixed to the bracket 2 are sleeved on the roller shafts, a double pulley 12 is arranged at one end of the conveying roller 1, a synchronous belt 13 is engaged with the double pulley 12, a reduction motor is arranged on the bracket 2, and the double pulley 12 is in transmission cooperation with the output end of the reduction motor through the synchronous belt 13.

[0038] The bracket 2 includes a right-angle plate 21, the right-angle plate 21 includes a horizontal plate and a vertical plate, a support plate 22 is welded and fixedly connected to the inner wall of the vertical plate, the shaft seat 11 is fixed to the support plate 22 through fastening bolts, a bottom plate 23 is welded and fixedly connected to the bottom of the vertical plate, and the reduction motor is fixed to the bottom plate 23 through fastening bolts.

[0039] Further, the reduction motor drives multiple conveying rollers 1 to move in the same direction through transmission.

[0040] As Figures 6-8As shown, the first positioning mechanism 3 includes a double-acting cylinder. The output end of the double-acting cylinder is connected to a special-shaped bent rod 32. There is a gap between the conveying rollers 1 and adjacent conveying rollers 1. The special-shaped bent rod 32 extends upward along the gap. A limit ring 33 is provided at the near end of the special-shaped bent rod 32. A bushing 34 is slidably fitted on the special-shaped bent rod 32, and the limit ring 33 is used to limit the bushing 34.

[0041] The fastening bolt of the double-acting cylinder is fixed to the bottom plate 23.

[0042] Furthermore, the bushing 34 can move axially along the special-shaped bent rod 32. During the movement of the sheet along with the conveying roller 1, the axial movement of the bushing 34 can reduce the conveying resistance.

[0043] As Figures 6-8 shown, the second positioning mechanism 4 includes a first support frame 41. An electric cylinder is provided at the top of the first support frame 41.

[0045] The pressing plate 43 corresponds to the conveying roller 1 up and down, and a rubber plate of the same shape is attached to the bottom surface of the pressing plate 43.

[0046] Furthermore, the telescopic movement of the electric cylinder will drive the pressing plate 43 to move synchronously. When the pressing plate 43 is closely attached to the sheet, it is beneficial to position the sheet and avoid displacement during the cutting process.

[0047] During use, the telescopic movement of the double-acting cylinder will drive the special-shaped bent rod 32 to move synchronously. As the two ends of the special-shaped bent rod 32 move closer to the center, the sheet will be positioned and straightened. Subsequently, after the sheet enters the cutting range of the laser cutting machine 6, the reduction motor stops moving, and the telescopic movement of the electric cylinder makes the pressing plate 43 closely attached to the sheet to achieve the positioning of the sheet and avoid displacement during the cutting process.
