Description

Technical Field

[0001] The utility model relates to the technical field of a laser processing carrier, in particular to a laser cutting carrier. Background Art

[0002] With the development of science and technology, traditional computer digital controlled precision machining can hardly meet the requirements of industrial products. In this case, laser processing technology has been rapidly developed and widely used. Especially when processing brittle materials such as glass, sapphire, and ceramics, laser drilling has the advantages of no wear and can process micro holes.

[0003] When using laser drilling, a blowing assembly is required to blow air into the drilled hole on the workpiece to be processed to blow out the dust in the drilled hole to prevent the dust from blocking the laser beam and affecting the quality of laser drilling. However, the blowing angle of the current blowing assembly is fixed and cannot be adjusted, resulting in incomplete blowing out of the dust, which affects the drilling quality of the workpiece to be processed.

[0004] The patent with application number 202221795751.3 discloses a technical solution of a laser cutting platform to solve the above-mentioned problems. However, in actual use, it is found that when the glass panel is laser cut, its laser cutting is not all straight cutting extending along the blowing pipe, but various, and the straight line cutting is not necessarily located directly above the blowing pipe, but a certain part is a straight line cutting, and a certain position is a circular cutting into a hole. Moreover, one of the cutting positions may be located directly above the blowing pipe, another cutting position may be located on the left side of the blowing pipe, and another cutting position may be located on the right side of the blowing pipe. When the cutting position is not in the blowing direction of the blowing pipe, the role of the blowing pipe is very limited.

[0005] In addition, when a glass panel is laser cut and the cut glass panel is transferred away and before the next glass panel is placed on the support bar, dust in the air may fall on the top surface of the support bar, causing the next glass panel to be cut to be sticky with dust when it contacts the support bar, which will affect the next process of the glass panel and require additional dust removal.

[0026] A negative pressure connecting tube 11 connected to each adsorption hole 4 is provided inside the support bar 2 along the length direction of the support bar 2. One end of the negative pressure connecting tube 11 is closed, and the other end extends out of the support bar 2 through the connecting tube A9.

[0027] The dust blowing pipe 5 comprises a plurality of unit pipes 8 which are coaxially and sealedly connected in sequence. The unit pipe 8 is provided with at least one dust blowing hole A7. Two adjacent unit pipes 8 are coaxially and sealedly fixedly connected so as to be rotatably adjustable.

[0028] The outer wall of one end of the unit tube 8 extends outwardly to be provided with a coaxially arranged connecting outer tube 19, and the inner wall of the other end extends outwardly to be provided with a coaxially arranged connecting inner tube 20. The inner wall of the connecting outer tube 19 and the outer wall of the connecting inner tube 20 match each other and are respectively provided with corresponding annular grooves for connecting sealing rings 21. The connecting outer tube 19 and the connecting inner tube 20 at the connecting ends of two adjacent unit tubes 8 are clamped and axially fixed.

[0029] The unit pipe 8 is provided with a plurality of dust blowing holes A7 at equal intervals along the axial direction.

[0030] The limiting side plates 13 are provided in plurality and are evenly spaced along the length direction of the support bar 2 . The limiting side plates 13 at the end where the limiting end plates 12 are located are connected to the limiting end plates 12 as a whole to form an “L”-shaped limiting plate 14 .

[0031] One end of the dust blowing pipe 5 is connected with a connecting pipe B10, and the connecting pipe B10 is located on the same side of the bottom box 1. The dust blowing holes B are respectively connected with connecting pipes C15, and the connecting pipes C15 are located on the side of the limiting end plate 12 facing away from the dust blowing holes B.

[0032] The connecting pipe B10 and the connecting pipe C15 are located on the same side of the bottom box 1 .

[0033] The dust suction port 3 is provided with an introduction ramp 16 at the side edges corresponding to the adjacent two side support bars 2, and the introduction ramp 16 extends into the bottom box 1 in a downwardly inclined direction away from the side edges.

[0035] When the present application is used, a template capable of displaying the position and shape of the panel that requires laser cutting is placed on the top surface of the support bar 2 through a limiting end plate 12, a limiting side plate 13 and an "L"-shaped limiting plate 14, and then the unit tubes 8 of each dust blowing tube 5 are adjusted and rotated according to the position of the laser cutting, so that the axes of the dust blowing holes A7 of the unit tubes 8 point to the laser cutting positions at the corresponding axial positions. The connecting pipe B10 of the dust-blowing hole A7 and the connecting pipe C15 of the dust-blowing hole B are respectively connected to the compressed air supply device, and the connecting pipe A9 of the adsorption hole 4 and the negative pressure connecting port 17 are respectively connected to the vacuum device; then, before the processed glass panel is limited and placed on the support bar 2, the dust-blowing hole B blows air to the top surface of the support bar 2 or the glass panel passing through the support bar 2 to ensure that there is no dust and impurities on the top surface of the support bar 2 or the surface of the glass panel; when the glass panel with cutting processing is limited by the limiting end plate 12, the limiting side plate 13 and the "L"-shaped limiting plate 14, the adsorption hole 4 negatively absorbs and fixes the processed glass panel on the top surface of the support bar 2, the dust suction port 3 sucks the air above the dust suction port 3 into the bottom box 1, and the dust-blowing hole B stops blowing.

The dust blowing pipe 5 swings back and forth while blowing air, which can increase the blowing range in the blowing direction, so that the blown air has a wider dust blowing range.

[0038] In order to achieve accurate processing and facilitate data management, laser cutting can also be controlled by a matching laser cutting automated remote control system, and a display screen is also provided on one side of the laser cutting platform. The display screen displays the model and size information of the platform used to match the glass panel being processed by the platform, and can also display whether there is a glass panel on the platform or whether the position of the glass panel is in place. In addition, the weight data and size data of the glass panel on the platform and the processing diagram to be laser cut are also displayed. When laser cutting is performed, the real-time position corresponding to the laser cutting device is also displayed in the processing diagram. The data displayed on the screen are transmitted to the production management control room through 4G or 5G communication technology, and the corresponding data are stored for future reference. The production management control room can directly set parameters for laser cutting or control it in other ways according to production needs. The set parameters and control signals are transmitted to the laser cutting device through 4G or 5G respectively, and displayed on the display screen of its corresponding platform. Thus, remote fine control and management of laser cutting glass panels are realized.
