Description

Technical Field

[0001] This utility model relates to the field of laser machine technology, and more specifically, to a positioning device for ceramic substrates on a laser machine. Background Technology

[0002] Laser machines mainly include laser cutting machines and laser engraving machines. The laser beam is focused by optical elements such as lenses or mirrors to form a very fine beam of light. This beam of light has extremely high energy density. When this high-energy light spot shines on the material being processed, its energy is absorbed by the material and converted into heat energy, causing the material to melt, vaporize, or burn, thereby achieving cutting or engraving.

[0003] Ceramic substrates are typically produced using alumina or aluminum nitride. They possess excellent mechanical and thermal properties. Subsequent processing includes cutting and drilling. Laser cutting offers advantages such as high processing precision, minimal heat-affected zone, and material savings. Ceramic substrates are often processed using laser machines.

[0004] Patent document CN221312887U discloses a high-quality laser processing machine, including a processing table. A movable frame is fixedly installed on the left side of the upper outer surface of the processing table, and a controller is fixedly installed on the upper part of the rear outer surface of the movable frame. A laser head is fixedly installed on one side of the movable frame. A groove is formed on the right side of the upper outer surface of the processing table, and a dial substrate is disposed on the upper part of the groove. A positioning component and a clamping component are fixedly installed on the upper outer surface of the processing table, and the dial substrate is located between the positioning component and the clamping component. The positioning component includes a first fixing plate, a first clamping plate, a first carrying plate, and an ear plate. This high-quality laser processing machine, through its positioning component, facilitates the positioning of the dial substrate. The clamping component facilitates the fixing of the dial substrate in conjunction with the positioning component and allows for control of the force applied to the dial substrate, thereby improving the processing quality. The above-mentioned technical solution has a fixture assembly set above a groove on the upper surface of the processing table. When clamping a large and thin ceramic substrate, the ceramic substrate is prone to deformation or breakage because there is no support at the bottom. In addition, the positioning assembly can only position the ceramic substrate in one direction.

[0005] Therefore, it is necessary to propose a positioning device for ceramic substrates on laser machines to solve the problems existing in the prior art. Utility Model Content

[0030] like Figure 1-6 As shown, a positioning device for a ceramic substrate on a laser machine includes a tray 1 set on a laser machine worktable 100, positioning plates 2 fixedly set on the edges of two adjacent sides on the top surface of the tray 1, and a fixing unit set on the top surface of the tray 1, the fixing unit including multiple support beams 3 fixedly set on the top surface of the tray 1.

[0031] Furthermore, the positioning plate 2 includes a first positioning plate 21 and a second positioning plate 22 that are fixedly connected to each other at one end.

[0032] Furthermore, the support beam 3 includes multiple horizontal beams 31 and multiple vertical beams 32 arranged in a cross pattern.

[0033] Furthermore, the fixing unit also includes a clamping plate 4, which is slidably mounted on the support beam 3;

[0034] A vertical plate 5 is fixedly installed on the top surface of the workbench 100 at the end away from the first positioning plate 21. A power cylinder 6 is fixedly installed on the side of the vertical plate 5 away from the positioning plate 21. The piston rod 7 of the power cylinder 6 passes through the vertical plate 5 and extends to the top of the support beam 3 and is hinged to the clamping plate 4.

[0035] Furthermore, a buffer layer 8 is fixedly provided on the side of the clamping plate 4 near the first positioning plate 21.

[0036] Furthermore, a pressure sensor 9 is installed between the clamping plate 4 and the buffer layer 8.

[0037] Furthermore, a negative pressure cavity 10 is formed inside the tray 1, and a negative pressure hole 11 is formed between every two adjacent crossbeams and every two adjacent longitudinal beams on the top surface of the tray 1. The negative pressure hole 11 is connected to the negative pressure cavity 10.

[0038] Furthermore, an air outlet 12 is opened on the bottom surface of the negative pressure chamber 10, and the air outlet 12 is connected to the vacuum pump through an air pipe.

[0039] Furthermore, the power cylinder 6 can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0040] Furthermore, bracket 1 is made of aluminum alloy.

[0041] The working principle of the above technical solution:

[0042] The tray 1 is set on the upper surface of the laser machine worktable 100 and is detachably connected to the worktable 100. The tray 1 is located below the laser cutting mechanism 200.

[0043] Two positioning plates 2 are fixedly installed on the edges of two adjacent sides on the top surface of the tray 1. One end of the two positioning plates 2 is fixedly connected to each other. When placing the ceramic substrate, the two sides of the ceramic substrate are pressed against the two positioning plates respectively. The positioning plates 2 play a positioning role for the ceramic substrate. The vertical line on the inner side of the connection between the two positioning plates 2 can be used as the origin of the coordinates during laser processing, which facilitates the positioning of the processing position during laser cutting. The same positioning principle applies to circular ceramic substrates.

[0044] A fixing unit is provided on the top surface of the tray 1. The fixing unit includes multiple support beams 3 fixedly installed on the top surface of the tray 1. The support beams 3 are used to support the ceramic substrate, so that the bottom surface of the ceramic substrate is kept at a certain distance from the top surface of the tray 1, and the laser is kept at a certain distance from the tray during processing. The support beams 3 are narrow beams, which can reduce the cutting during laser cutting, reduce heat transfer, and prevent the tray 1 from deforming. The tray 1 can be made of aluminum alloy material.

[0045] The positioning plate 2 includes a first positioning plate 21 and a second positioning plate 22 that are fixedly connected to each other at one end. The first positioning plate 21 and the second positioning plate 22 can be set vertically.

[0046] The fixing unit also includes a clamping plate 4, which is slidably mounted on the support beam 3; a vertical plate 5 is fixedly mounted on the top surface of the workbench 100 at the end away from the first positioning plate 21, and a power cylinder 6 is fixedly mounted on the side of the vertical plate 5 away from the positioning plate 21. The piston rod 7 of the power cylinder 6 passes through the vertical plate 5 and extends to the top of the support beam 3 and is hinged to the clamping plate 4. The power cylinder 6 is a pneumatic cylinder, hydraulic cylinder, or electric cylinder. The clamping plate 4 is positioned opposite to the first positioning plate 21. After the ceramic substrate is placed on the support beam and positioned... The power cylinder 6 is activated, causing the piston rod 7 to extend and push the clamping plate 4 towards the ceramic substrate, clamping the ceramic substrate between the clamping plate 4 and the first positioning plate 21. The buffer layer 8 on the clamping plate 4 can prevent the clamping plate 4 from damaging the ceramic substrate. A pressure sensor 9 is set between the buffer layer and the clamping plate to control the pressure during clamping and prevent damage to the ceramic substrate. The clamping plate 4 is hinged to the piston rod 7, and the clamping plate 4 can rotate in the horizontal plane, so that the clamping plate can adapt to the clamping of irregular ceramic substrates.

[0047] The support beam 3 includes multiple horizontal beams 31 and multiple vertical beams 32 arranged in a crisscross pattern. A negative pressure chamber 10 is opened inside the support plate 1. A negative pressure hole 11 is opened between every two adjacent horizontal beams and every two adjacent vertical beams on the top surface of the support plate 1. The negative pressure hole 11 is connected to the negative pressure chamber 10. An air outlet 12 is opened on the bottom surface of the negative pressure chamber 10. The air outlet 12 is connected to a vacuum pump through an air pipe. When the ceramic substrate is cut, the vacuum pump is turned on. The vacuum pump reduces the pressure in the negative pressure chamber 10. The negative pressure chamber 10 can suck out the dust generated during cutting in the space formed between the multiple horizontal beams 31 and multiple vertical beams 32 through the negative pressure hole 11, preventing the dust from accumulating on the upper surface of the support beam 3 and affecting the level of the ceramic substrate during subsequent installation. During the dust extraction process, the air flow can also carry away the heat transferred to the support beam 3 during laser cutting, preventing the support beam from deforming due to heat, which would cause deformation of the ceramic substrate and affect the processing accuracy.

[0048] The beneficial effects of the above technical solution are as follows:

[0049] The positioning device for ceramic substrates on a laser machine described in this utility model has multiple mutually spaced support beams on the top surface of the tray. These beams can support the ceramic substrate, reduce the heat absorbed by the tray during laser processing, and prevent the tray from deforming. The two intersecting positioning plates can improve the positioning accuracy of the ceramic substrate.
