Description

Technical Field

[0001] This utility model belongs to the field of laser processing equipment technology, and in particular relates to an automatic edge-aligning worktable for a three-beam laser equipment. Background Technology

[0002] Laser cutting utilizes the energy released when a laser beam irradiates the surface of a workpiece to melt and evaporate the workpiece, thereby achieving the purpose of cutting and carving.

[0003] The beam laser cutting equipment includes a laser gun assembly and a conveyor platform. Sheet metal is conveyed to the laser gun assembly via the conveyor platform, and the laser gun assembly cuts the sheet metal by moving longitudinally and laterally.

[0004] However, existing beam laser cutting equipment still has the following problems:

[0005] 1. It only has one set of laser cutting components, resulting in low cutting efficiency and making it unsuitable for continuous, uninterrupted cutting of sheet metal.

[0006] 2. The conveyor platform lacks an edge-mounting component, causing the sheet material to lose its straightness after being conveyed by the platform. This necessitates repositioning the sheet material after it enters the area under the laser cutting component, otherwise it will cause cutting errors.

[0007] 3. Longer sheet metal pieces often have their ends warped due to their own weight, making them more likely to collide with the laser cutting head. Utility Model Content

[0008] The purpose of this invention is to provide an automatic edge-aligning worktable for a three-beam laser device, in order to solve the problems existing in the background technology.

[0009] The objective of this utility model is achieved through the following technical solution:

[0010] An automatic edge-aligning worktable for a three-beam laser equipment includes a conveying platform and laser cutting components. The three sets of laser cutting components are arranged along the feeding direction on the conveying platform and are slidably connected to the conveying platform.

[0011] The conveying platform includes a base, mounting plate, rollers, and edge guard assembly;

[0012] The two sets of mounting plates are symmetrically fixed on the upper sides of the base;

[0013] Multiple rollers are arranged parallel to each other and at an angle to the feeding direction. The two sides of each roller are rotatably connected to the base. Multiple discs are evenly arranged on each roller, and the discs on adjacent sets of rollers are arranged alternately.

[0014] The side guard assembly is located inside one side of the mounting plate, and the side guard assembly includes a push plate, a connecting rod assembly, and a telescopic cylinder;

[0015] A guide plate is provided on the inner side of the end of the pusher plate near the discharge end;

[0016] The conveying platform is equipped with a limit rod at one end near the material discharge end.

[0017] Furthermore, the push plate is located above the highest point of the disc, and the length of the push plate is adapted to the length of the conveying platform. Multiple sets of the connecting rod assemblies are evenly arranged along the conveying direction of the push plate. One end of the connecting rod assembly is hinged to the push plate, and the other end of the connecting rod assembly is hinged to the mounting plate. The cylinder seat of the telescopic cylinder is fixed on the mounting plate, and the piston rod of the telescopic cylinder passes through the mounting plate and is hinged to the middle of the connecting rod assembly.

[0018] Furthermore, the guide plate is fixed on the push plate. The guide plate includes a horizontal section and a guide section. The guide section is located on the side near the feed end of the conveying platform. The guide section is arranged at an angle, and the height of the guide section is higher than the height of the horizontal section.

[0019] Furthermore, the bottom of the limiting rod is provided with a telescopic component, and the top of the limiting rod is provided with a sensor on the side facing the incoming material.

[0020] Furthermore, the two sides of the roller are rotatably connected to the base through bearing seats, and a double row of sprockets is provided on one side of the roller, with the double rows of sprockets of two adjacent rollers connected by a chain belt.

[0021] Furthermore, the angle between the roller and the push plate is 80°.

[0022] The beneficial effects of this utility model are:

[0023] 1) After the sheet material enters the conveying platform, the inclined rollers and discs make the sheet material move towards one side of the mounting plate, ensuring that the sheet material is conveyed along one side of the mounting plate.

[0024] 2) Three sets of laser cutting components can simultaneously cut a single sheet on the conveyor platform or cut multiple sheets simultaneously.

[0025] 3) The telescopic cylinder drives the connecting rod assembly, which pushes the plate against the mounting plate on the opposite side, thereby limiting and clamping it, facilitating the subsequent cutting operation of the laser cutting assembly. Attached Figure Description

Detailed Implementation

[0031] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. 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 protection scope of this utility model.

[0032] See Figures 1-4 This utility model provides a technical solution:

[0033] like Figures 1-4 As shown, an automatic side-aligning worktable for a three-beam laser equipment includes a conveying platform 1 and laser cutting components 2. Three sets of the laser cutting components 2 are arranged on the conveying platform 1 along the feeding direction and are slidably connected to the conveying platform 1.

[0034] The conveying platform 1 includes a base 11, a mounting plate 12, rollers 13, and a side guard assembly 14;

[0035] The two sets of mounting plates 12 are symmetrically fixed on the upper sides of the base 11;

[0036] Multiple rollers 13 are arranged parallel to each other and at an angle to the feeding direction. The two sides of each roller 13 are rotatably connected to the base 11. Multiple discs 131 are evenly provided on each roller 13, and the discs 131 on adjacent sets of rollers 13 are arranged alternately.

[0037] With the above technical solution, after the plate enters the conveying platform 1, the inclined rollers 13 and discs 131 make the plate move towards the mounting plate 12 on one side, completing the initial positioning of the plate and ensuring that the plate is conveyed along one side of the mounting plate 12 to the bottom of the laser cutting assembly 2.

[0038] When the sheet metal comes into contact with the limiting rod 15 on one side of the discharge end, the roller 13 stops rotating. At this time, the edge guard assembly 14 is activated, and the telescopic cylinder 143 drives the connecting rod assembly 142 to push the push plate 141 to press the sheet metal against the mounting plate 12 on the opposite side, thereby limiting and clamping it, which facilitates the subsequent cutting operation of the laser cutting assembly 2. At the same time, three sets of laser cutting assemblies 2 are set on the conveying platform 1, which can cut a sheet metal on the conveying platform 1 at the same time or cut multiple sheets metal at the same time, which greatly improves the processing efficiency.

[0039] like Figures 1-2 As shown, the specific working principle of the side guard assembly 14 is as follows: The side guard assembly 14 is located inside one side of the mounting plate 12. The side guard assembly 14 includes a push plate 141, a connecting rod assembly 142, and a telescopic cylinder 143. The push plate 141 is located above the highest point of the disc 131. The length of the push plate 141 is adapted to the length of the conveying platform 1. Multiple sets of connecting rod assemblies 142 are evenly arranged along the conveying direction of the push plate 141. One end of the connecting rod assembly 142 is hinged to the push plate 141, and the other end of the connecting rod assembly 142 is hinged to the mounting plate 12. The cylinder seat of the telescopic cylinder 143 is fixed on the mounting plate 12, and the piston rod of the telescopic cylinder 143 passes through the mounting plate 12 and is hinged to the middle of the connecting rod assembly 142.

[0040] By activating the piston rod of the telescopic cylinder 143, the connecting rod assembly 142 is driven to move, which in turn is converted into the horizontal movement of the push plate 141. Through the combined action of the telescopic cylinder 143 and the connecting rod assembly 142, the push plate 141 can push the plate to abut against the mounting plate 12 on the opposite side to complete the limiting and clamping.

[0041] Continue as Figures 1-2 As shown, the two sides of the roller 13 are rotatably connected to the base 11 through bearing seats 132. One side of the roller 13 is provided with a double row of sprockets 133, and the double row of sprockets 133 of two adjacent rollers 13 are connected by a chain belt.

[0042] The inclined rollers 13 allow the sheet metal to move closer to the mounting plate 12 on one side, ensuring the proper movement path of the sheet metal. Preferably, the angle between the rollers 13 and the push plate 141 is 80°. Multiple discs 131 are also mounted on the rollers 13, reducing the contact area with the sheet metal and effectively protecting its surface. The gaps between adjacent discs 131 facilitate the discharge of waste material after laser cutting.

[0043] like Figure 3As shown, the working principle of the push plate 141 is as follows: a guide plate 144 is provided on the inner side of the end of the push plate 141 near the discharge end; the guide plate 144 is fixed on the push plate 141, and the guide plate 144 includes a horizontal section 145 and a guide section 146. The guide section 146 is located on the side near the feed end of the conveying platform 1. The guide section 146 is arranged at an angle, and the height of the guide section 146 is higher than the height of the horizontal section 145.

[0044] The raised part at the front end of the sheet material will first pass through the guide section 146 and then be pressed down to the horizontal section 145 to ensure that the sheet material at the output end will not be raised, avoid interference between the sheet material and the laser cutting equipment, and ensure processing safety.

[0045] like Figure 4 As shown, the limiting rod 15 is located at the discharge end of the conveying platform 1. The bottom of the limiting rod 15 is provided with a telescopic component. The limiting rod 15 is located between the gaps of adjacent discs 131. The top of the limiting rod 15 is provided with a sensor on the side facing the incoming material.

[0046] The limit rod 15 extends to the highest point of the disc 131. When the plate comes into contact with the limit rod 15, the sensor receives a signal, causing the roller 13 to stop rotating. Then the edge-stopping assembly 14 and the laser cutting equipment work. After the plate is cut, the limit rod 15 moves down through the telescopic assembly to ensure that the plate passes smoothly.

[0047] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
