Technical Field

[0001] This utility model belongs to the field of machining technology, and in particular relates to a slag removal assembly for a laser processing platform and a laser processing equipment. Background Technology

[0002] For laser processing platforms, debris often remains on the processing table. For sheet materials (such as plastic sheets, metal foil sheets, leather sheets, circuit boards, etc.), when they are laid flat on the processing table, the debris on the table can make the sheet uneven, and may even cause marks on the back of the sheet, affecting product quality. Debris on the surface of circuit boards can block subsequent processing areas, causing quality problems in laser processing. If there were a mechanical debris removal assembly and method, it would solve the problems of fixing the workpiece before processing and the surface cleanliness after processing.

Detailed Implementation

[0037] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0038] This utility model also provides a slag removal assembly for a laser processing platform, such as... Figures 1-3 As shown, the laser processing platform slag removal assembly includes a processing table 1, a slag removal component 2, and a moving component 3. The processing table 1 has a working surface for placing workpieces. The processing table 1 and the slag removal component 2 move relative to each other under the drive of the moving component 3, so that the slag removal component 2 can remove slag from the working surface or the workpiece. This allows the moving component to create relative movement between the slag removal component and the processing table, enabling the slag removal component to clean the working surface of the processing table or the workpiece placed on the working surface. In this embodiment, the working surface of the processing table 1 is either flat or curved, allowing the working surface of the processing table to be adaptively set according to the shape of the workpiece. In this embodiment, the workpiece can be a sheet material, which can be laid on the processing table for processing. Of course, the slag may remain on the processing table or on the workpiece. Whether cleaning the processing table alone or cleaning the workpiece placed on the processing table, the working mode of the slag removal component is the same.

[0039] The following examples all focus on cleaning the working surface of the processing table.

[0040] In this embodiment, the processing table 1 is a negative pressure adsorption platform or a negative pressure fixture plate. For the negative pressure adsorption platform, it can adsorb the workpiece onto the working surface in the form of negative pressure. However, the slag adhering to the working surface is difficult to remove by the negative pressure adsorption platform, requiring the use of a slag removal component to remove the slag. For the negative pressure fixture plate, the slag removal component can move and brush the slag adhering to the working surface away from the processing table. Both the negative pressure adsorption platform and the negative pressure fixture plate are existing technologies in this field and will not be described in detail here.

[0041] like Figure 1 and Figure 2 As shown, in this embodiment, the moving component can be a single unit. It can be a component that drives the processing table to move while the slag removal component is static (in which case the included brush roller rotates), or it can be a component that drives the slag removal component to move while the processing table remains static, such as... Figure 3 As shown, two moving parts can also be provided. One moving part drives the processing table to move, while the other drives the slag removal part to move. In short, the processing table and the slag removal part can move relative to each other. (The robotic arm that drives the processing table can be a linear drive, a two-dimensional drive, or a three-dimensional drive, while the robotic arm that drives the slag removal part can be a robotic arm, a linear drive, a two-dimensional drive, or a three-dimensional drive.) In this embodiment, the robotic arm can be a six-axis robotic arm. The linear drive can be a linear module or a telescopic cylinder (telescopic pneumatic cylinder, telescopic electric cylinder, or telescopic hydraulic cylinder). The two-dimensional drive can be an XY two-axis slide module, and the three-dimensional drive can be an XYZ three-axis slide module.

[0042] In this embodiment, when the moving component is a linear drive component, it drives the slag removal component across the entire width of the processing table's working surface, thus performing cleaning and slag removal operations on the working surface. When the moving component is a two-dimensional drive component, it drives the slag removal component downwards and also drives it across the entire width of the processing table's working surface, thus performing cleaning and slag removal operations on the working surface. After slag removal is completed, the moving component then drives the slag removal component upwards to its reset position. When the moving component is a three-dimensional drive component, it drives the slag removal component to move in three dimensions within space, thereby performing cleaning operations on the working surface.

[0043] When only one moving part is set, the processing table remains stationary, while the slag removal part can move under the drive of the moving part to clean the working surface of the processing table, or the slag removal part remains stationary, while the processing table moves passively to be cleaned by the slag removal part.

[0044] Of course, the moving part 3 is preferably a linear drive, a two-dimensional drive, or a three-dimensional drive.

[0045] In one embodiment of this utility model, the slag removal component 2 includes a roller 21 and a drive component 22, such as... Figure 4As shown, the driving component 22 is connected to the roller 21 via a transmission connection. The driving component 22 drives the roller 21 to rotate. The roller 21 is a brush roller or a dust-adhesive roller, so that the roller can rotate under the drive of the driving component to remove slag from the processing table. At this time, the slag removal component also includes a mounting base 26. In this embodiment, the mounting base is an n-shaped frame. The roller is placed in the mounting base 26, and its two ends are rotatably connected to the two ends of the mounting base 26, respectively. The driving component can be installed at one end of the mounting base 26, and its driving end is connected to one end of the roller assembly via a transmission connection. The driving component is used to drive the roller to rotate. At this time, if the slag removal component moves under the drive of a moving component, the driving end of the moving component is connected to the mounting base 26, and the moving component is preferably any one of a linear driving component, a two-dimensional driving component, or a three-dimensional driving component.

[0046] In this embodiment, the roller surface of the brush roller is covered with brush filaments (the brush filaments can be brush bristles, steel wires or flexible plastic filaments), and the dust-adhesive roller has an adhesive layer on its roller surface, which is existing technology and will not be described in detail here.

[0047] Preferred, such as Figure 5 As shown, in this embodiment, when the roller 21 is a brush roller, its interior is hollow, and the roller surface is evenly distributed with blowing holes 211 communicating with its interior. One end of the roller 21 is coaxially provided with an air inlet 212 communicating with its interior, and the air inlet 212 is tubular. The air inlet 212 is used to connect to an air source, and the air source is used to introduce airflow into the roller 21 to perform self-cleaning treatment on the roller 21. This allows the roller to also spray airflow on its surface for self-cleaning. At this time, the mounting base also has a rotary joint that mates with the air inlet, and the air inlet is connected to the air source through the rotary joint via a pipe. In this embodiment, the air source can be an air compressor. In this embodiment, when the brush roller is self-cleaning, the air compressor blows compressed air into the roller, thereby causing the blowing holes on the roller surface to blow away the debris adhering to the bristles.

[0048] In another embodiment of this utility model, the slag removal component 2 includes a brush 23 and a drive component 22, such as... Figure 7As shown, the driving component 22 is pulsatorically connected to the brush 23. The driving component 22 drives the brush 23 to swing or rotate, thus allowing the brush to perform brushing operations on the processing table under the drive of the driving component. In this embodiment, the slag removal component also includes a mounting base 26, but in this embodiment, the mounting base can be a horizontally arranged mounting plate. The upper end of the brush has a vertically arranged rotating shaft, and the rotating shaft passes through the mounting base and is rotatably connected to the mounting base. The driving component is installed on the upper end of the mounting base and is pulsatorically connected to the rotating shaft. The driving component drives the brush to rotate. The lower end of the sweeping brush is covered with bristles, similar to the sweeping brushes on both sides of a garbage sweeper, with bristles evenly distributed at its lower end. In this embodiment, when the slag removal component moves, the moving component driving the movement can be a robotic arm, a linear drive, a two-dimensional drive, or a three-dimensional drive. The driving end of the moving component is connected to the mounting base. In this embodiment, the moving component is preferably a two-dimensional or three-dimensional drive. If the moving component is a robotic arm, it can be placed next to the processing table. When the working surface of the processing table needs cleaning, the robotic arm drives the sweeping brush to move to clean the working surface of the processing table. In this embodiment, the sweeping brush also has bristles (the bristles can be brush bristles or flexible plastic filaments). For the slag removal component, it is in working state when it moves close to the processing table or workpiece under the action of the moving component, and in standby state when it moves away from the processing table or workpiece under the action of the moving component.

[0049] In this embodiment, when the slag removal component includes a brush roller or a sweeping brush, its rotation speed in the working state is at least 1 revolution / second. At this time, the brush bristles of the slag removal component can perform cutting / sandblasting functions on the working surface of the processing table or the surface of the workpiece, so as to remove the slag that is difficult to remove from the surface of the processing table or the workpiece.

[0050] In another embodiment of this utility model, the slag removal component 2 includes a blower / suction head 24 and a blower 25, such as... Figure 8 and Figure 9 As shown, the blow-suction head 24 is connected to the blower 25. The blow-suction head 24 is used to blow or suck up the surface of the processing table 1, so that the slag on the processing table can be blown or sucked away by the blow-suction head. The blow-suction head can be straight and hollow inside, and has a strip-shaped blow-suction hole 241 arranged along its length on one side. The blow-suction head also has a ventilation port 242, which can be connected to the blower through a flexible pipe (it can be connected to the air inlet or outlet of the blower, that is, the blow-suction head can blow air to sweep up the slag or suck air to remove the slag). In this embodiment, if the slag removal component is movable under the drive of the moving component, the driving end of the moving component can be directly connected to the blow-suction head. Moreover, in this embodiment, the moving component can be a robotic arm, a linear drive component, a two-dimensional drive component, or a three-dimensional drive component.

[0051] like Figure 6 As shown, when the slag removal component includes a brush roller, a straight slag collection trough can be added to one side of the mounting base. The opening of the slag collection trough faces the brush roller, and a negative pressure interface can be provided at the bottom of the slag collection trough to connect with the dust collection equipment. At this time, the slag thrown up by the brush roller will be collected in the slag collection trough and eventually sucked away by the dust collection equipment, which is similar to a dust collector.

[0052] In another aspect, this utility model also provides a laser processing device, which includes a slag removal assembly for a laser processing platform as described in Embodiment 1. This assembly has a simple structure and produces foil workpieces with excellent flatness after processing. In this embodiment, the laser processing device can be a frame-based system, and in this embodiment, all moving parts can be mounted on the frame.

[0053] In another aspect, this utility model also provides a processing method for the laser processing equipment as described above, comprising the following steps:

[0054] Place the workpiece on the work surface;

[0055] Laser processing of the workpiece;

[0056] The processing table and the slag removal component move relative to each other under the drive of the moving parts to clean the slag on the workpiece;

[0057] After the workpiece is removed, the machining table and the slag removal component continue to move relative to each other under the drive of the moving parts to clean the slag on the working surface. The machining process is simple and can avoid the slag residue on the workpiece and the working surface during machining, which would affect the machining accuracy.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
