Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment technology, specifically to a top-surface adsorption type high-speed take-up and take-up mechanism. Background Technology

[0002] In laser cutting of silicon steel plates, in order to ensure cutting accuracy and processing stability, a support mechanism is usually set under the silicon steel plate to be cut. Its core function is to limit the height of the silicon steel plate and prevent it from shifting due to vibration or thermal deformation during the cutting process.

[0003] Traditional support mechanisms often employ tiltable support platforms. Their working principle is as follows: during cutting, the support platform remains horizontal to support the silicon steel sheet; after cutting, the support platform tilts downwards, allowing the cut waste to slide down the tilted surface, thus releasing the processing area for the next cut. However, this structure has significant drawbacks: the tilting action of the support platform requires an additional drive device, which is time-consuming (typically accounting for 15%-20% of the total processing cycle), severely restricting the production efficiency of laser cutting equipment; furthermore, waste jamming is prone to occur during the tilting waste removal process, further affecting processing continuity. Utility Model Content

[0004] The purpose of this invention is to address the problem of low waste discharge efficiency in traditional tiltable support platforms by providing a top-adsorption type high-speed loading and unloading mechanism. By changing the support method, it enables rapid waste discharge and improves the production efficiency of laser cutting of silicon steel plates.

[0005] The technical solution provided by this utility model is a top-adsorption type high-speed take-up and take-down mechanism, including a vertical support, a slide rail structure fixed on the top of the vertical support, and an adsorption structure connected to the slide rail structure.

[0006] The slide rail structure includes a sliding guide rail fixedly connected to the top of the vertical support, a single-axis module disposed in the middle of the sliding guide rail, and a movable support slidably connected to the sliding guide rail and the single-axis module.

[0007] The adsorption structure includes a base plate connected to a movable support, multiple cylinders disposed below the base plate, and an adsorption plate connected to the output end of the cylinders.

[0008] The adsorption plate is provided with multiple electromagnets that penetrate the adsorption plate.

[0009] As a preferred embodiment of this utility model, the sliding guide rail is symmetrically arranged on the top of the vertical bracket via a support plate, and the length of the sliding guide rail on the vertical bracket is less than 1 / 2 of its total length.

[0010] As a preferred technical solution of this utility model, the two ends of the movable bracket protrude from the side of the support plate and are located below the support plate and fixedly connected to the base plate, forming a movable part with a "U"-shaped structure.

[0011] As a preferred embodiment of this utility model, the single-axis module is a lead screw guide rail with a servo motor at one end, and the movement direction of the single-axis module is the same as the direction of the sliding guide rail.

[0012] As a preferred embodiment of this utility model, the number of cylinders is at least three, and the cylinders are evenly arranged at the lower edge of the base plate.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] 1. Significantly improved waste discharge efficiency: The adsorption plate adopts a top adsorption and bottom suspension design. After cutting, it is only necessary to disconnect the electromagnet power supply and retract the cylinder. The waste can be discharged directly from the suspended part under the adsorption plate without waiting for the support platform to tilt. The single waste discharge time is shortened by more than 80%.

[0015] 2. High support stability: The adsorption plate is evenly supported by multiple cylinders (at least three), and with the electromagnetic adsorption force of the electromagnet, it can achieve stress-free and uniform support for the silicon steel plate, effectively avoiding deformation or displacement of the plate due to uneven support during the cutting process.

[0016] 3. Compact structure and strong adaptability: The sliding guide rail is symmetrically set on the top of the vertical bracket and the installation length is less than 1 / 2 of the total length. Combined with the structural design of the "U"-shaped moving bracket, it not only ensures the sliding stroke of the moving bracket, but also reduces the overall space occupied by the mechanism, making it suitable for cutting silicon steel plates of different sizes and specifications.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1:

[0023] As per the instruction manual Figure 1 As shown, the vertical support 1 is a rectangular frame welded from Q235 steel plate. The top of the support plate 9 is fixed with bolts. Two pairs of parallel and symmetrically arranged sliding guide rails 2 are provided above the support plate 9. The sliding guide rail 2 is a linear ball bearing guide rail that extends along the length of the support plate 9. Its installation length on the support plate 9 is 40% of the total length of the guide rail, and the remaining part extends to the outside of the support plate 9 to increase the sliding stroke.

[0024] In this utility model, the single-axis module 3 is a ball screw linear module, whose screw axis is consistent with the extension direction of the sliding guide rail 2. One end of the screw is connected to the output shaft of the servo motor through a coupling. The servo motor and the single-axis module 3 are both fixed between the two sliding guide rails 2 on the support plate 9. The movable bracket 4 is a rectangular frame spliced ​​from aluminum alloy profiles. Its top two sides are slidably connected to the sliding guide rail 2 through sliders, and the middle part is fixedly connected to the slider of the single-axis module 3, so that the entire movable bracket 4 can be moved along the sliding guide rail 2 by the drive of the single-axis module 3. The left and right ends of the movable bracket 4 extend outwards, exceed the side of the support plate 9 and bend downwards by 90°, and are fixed to the upper surface of the base plate 5 by welding to form a "U"-shaped movable part.

[0025] In this utility model, the base plate 5 is made of Q345 steel plate. The base plate 5 has a triangular structure. Three cylinders 6 are evenly distributed on the edge of the lower surface of the triangular section (the number can be adjusted according to the weight and cutting shape of the thin steel plate 10, but at least three). The cylinder body of the cylinder 6 is fixed to the base plate 5 by bolts. The piston rod end is connected to the adsorption plate 7 through a connecting plate. The adsorption plate 7 is made of stainless steel plate with a thickness of 10mm. It is completely suspended below and has 20 electromagnets 8 embedded inside (arranged in a 5×4 matrix). The top surface of the electromagnet 8 protrudes from the upper surface of the adsorption plate 7, and the bottom surface is flush with the lower surface of the adsorption plate 7. It is connected to an external power source through wires.

[0026] Working principle

[0027] 1. Adsorption and support stage: When the thin steel plate 10 is transported to the upper part of the processing area, the servo motor drives the single-axis module 3 to move, which in turn moves the moving bracket 4 along the sliding guide rail 2 to directly above the thin steel plate 10. Then, the piston rod of the cylinder 6 extends and pushes the adsorption plate 7 downward to contact the upper surface of the thin steel plate 10. Finally, the electromagnet 8 is energized to generate electromagnetic attraction, which stably adsorbs the thin steel plate 10 onto the adsorption plate 7, completing the support and positioning before cutting.

[0028] 2. Cutting and processing stage: The laser cutting head cuts the thin steel plate 10. At this time, the adsorption plate 7 bears the cutting reaction force through electromagnetic attraction and the supporting force of the cylinder 6, ensuring the positional accuracy of the thin steel plate 10.

[0029] 3. Waste removal and reset stage: After cutting, the electromagnet 8 is de-energized and loses its attraction, the piston rod of the cylinder 6 retracts, and drives the adsorption plate 7 to move upward; since the adsorption plate 7 is completely suspended, the cut waste material falls directly from the suspended position into the waste collection device below under the action of gravity; finally, the servo motor drives the single-axis module 3 in the reverse direction, driving the moving bracket 4 to reset to the initial position, ready for the next adsorption support.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
