Description

Technical Field

[0001] The invention relates to the technical field of ceramic laser drilling, in particular to a laser drilling machine for ceramic parts. Background Art

[0002] Due to the high hardness and brittleness of ceramic materials, traditional drilling methods often fail to achieve the desired effect. Laser drilling technology can effectively solve this problem. Laser processing technology is a new processing technology that uses the characteristics of the interaction between laser beams and materials to cut, drill and micro-process materials. Ceramic laser drilling machines can produce ceramic holes with very high precision. The holes are smooth and burr-free, and the aperture size can be very small. It will not cause thermal deformation, burns and other problems to the ceramics, avoiding damage to the ceramics caused by traditional drilling methods.

[0003] Existing ceramic laser drilling machines have many technical defects when in use. First, each group of ceramic parts is placed directly on the positioning tooling by hand. On the one hand, there are errors in the positioning accuracy, which leads to the deviation of the drilling position. On the other hand, manual loading is time-consuming and labor-intensive, and the overall work efficiency is low. Second, after laser cutting, the upper and lower surfaces of the ceramic parts are easily contaminated with cooling residues or dust, resulting in contamination of the ceramic parts after drilling. When cooling the fiber laser, the existing water cooling system has poor cooling effect due to the limited contact area. In particular, when the fiber laser is working continuously, the fiber laser and the cutting head are prone to overheating.

[0004] To sum up, considering that the existing facilities cannot meet the work needs, we propose a laser drilling machine for ceramic parts. Summary of the invention

[0025] The present invention provides a laser drilling machine for ceramic parts through improvement, which has the following significant improvements and advantages compared with the prior art:

[0026] Start the servo motor to drive the pinion to rotate, and through a series of transmissions, the drive roller is caused to make circular motion. When the drive roller moves, the rotary slide and the slider interact with each other, causing the push rod to move linearly to the right in the movable push rod groove, pushing the ceramic plate in the discharge channel, so that the ceramic plate slides into the punching fixture seat, and the ceramic plate is accurately positioned. When the ceramic plate punching operation is completed, the push rod continues to push the ceramic plate to move linearly to the right, and the ceramic plate passes through the positioner and enters the interior of the cleaning box through the feed port, achieving the purpose of automatic pushing and conveying, saving time and effort.

[0027] A positioner is designed, and the ceramic plate leaves the discharge channel and slides into the punching fixture until it stops moving after encountering resistance from two sets of stop blocks. The ceramic plate is accurately positioned. When the push rod continues to push the ceramic plate to the right in a straight line, the arc surfaces of the ceramic plate and the stop blocks squeeze each other, causing the two sets of stop blocks to rise, allowing the ceramic plate to pass through the positioner smoothly, reducing manual errors and improving positioning accuracy.

[0028] Several groups of ceramic parts are stacked in sequence and placed in the arrangement storage cavity. When the push rod withdraws from the discharge channel, under the pressure of the pressure plate, the bottom group of ceramic plates in the arrangement storage cavity are automatically replenished into the discharge channel, achieving the effect of automatic feeding, saving time and effort.

[0029] Start the uniform speed motor to drive one group of cleaning rollers to rotate at a uniform speed, and through the upper and lower meshing of the synchronous gears, make the other group of cleaning rollers directly above move in the opposite direction. At the same time, the two groups of cleaning rollers are driven by sprockets and synchronous chains to make the upper and lower rows of cleaning roller structures move synchronously in the same direction. On the one hand, the cleaning rollers use the moving wiping cloth to wipe the upper and lower surfaces of the ceramic plate to solve the cleaning problem. On the other hand, there is friction between the upper and lower groups of cleaning rollers and the upper and lower surfaces of the ceramic plate, causing the ceramic plate to move from left to right, thereby achieving the purpose of cleaning and transporting.

[0030] Start the small booster pump and inject the liquid condensing medium in the condensing medium tank into the lower position of the auxiliary vaporization flow channel through the injection pipe. During the flow of the liquid condensing medium in the auxiliary vaporization flow channel, it absorbs the heat in the fiber laser and continues to vaporize, and takes away the heat generated by the fiber laser to achieve the purpose of automatic cooling. The vaporized medium rises in the auxiliary vaporization flow channel and continuously flows from the guide pipe into the spiral condenser tube. When the spiral condenser tube moves in a spiral long distance, it fully contacts the inner wall of the condenser tube. The vaporized medium is re-liquefied into liquid condensing medium and flows into the condensing medium tank. This cycle plays a role in auxiliary heat dissipation. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] Furthermore, a discharge base 30 is horizontally fixed on the upper end surface of the machine base 1 and is located on the right side of the limiting movable platform 10. A discharge channel 32 for the push rod 16 to extend into is provided inside the discharge base 30. A storage box 31 is fixed to the upper end of the discharge base 30. An arrangement storage cavity 33 for stacking a plurality of groups of ceramic plates 34 is provided inside the storage box 31 (the size of the arrangement storage cavity 33 and the ceramic plates 34 are adapted). The arrangement storage cavity 33 is connected to the discharge channel 32. The push rod 16 pushes the ceramic plates 34 in the discharge channel 32 into the punching fixture seat 76, as shown in FIG. Figure 1 and 6 shown.

The two move relative to each other and play a limiting role. A pressing plate 37 acting on the ceramic plate 34 is welded to the lower end of the pressing rod 35.

The first spring columns 40 and the second spring columns 41 are connected by a tension spring 42, and the tension spring 42 is in a stretched state, such as Figure 6 and 7 shown.

[0061] Furthermore, a cleaning box 50 is provided on the upper end surface of the base 1 and on the right side of the punching fixture seat 76. Figure 1-3 shown.

[0062] In this embodiment, the left end surface of the cleaning box 50 is provided with a feed port 51 for the ceramic plate 34 to extend into, the feed port 51 and the size of the ceramic plate 34 match, the feed port 51 and the punching fixture seat 76 are on the same horizontal plane, and the right end surface of the cleaning box 50 is provided with a discharge port 56 for the ceramic plate 34 to discharge, and the discharge port 56 and the size of the ceramic plate 34 match, as shown in FIG. Figure 2 and 10 shown.

[0063] In this embodiment, the cleaning box 50 is internally provided with two rows of cleaning roller structures, each row of cleaning roller structures includes a plurality of groups of cleaning rollers 9 arranged equidistantly, and a movement gap 52 is formed between the upper and lower groups of cleaning rollers 9 to act on the ceramic plate 34. The size of the movement gap 52 is adapted to the thickness of the ceramic plate 34. Fig.11 shown.

[0064] Specifically, the cleaning roller 9 includes a roller body 91, a wiping cloth 92, a short shaft 93, a second bearing seat 94 and a sprocket 95. Fig.12 shown.

[0065] In this embodiment, the outer surface of the roller body 91 is wrapped with a wiping cloth 92, and there is flexible contact between the wiping cloth 92 and the outer surface of the ceramic plate 34, which has a protective effect. Short shafts 93 are symmetrically welded at both ends of the roller body 91. Each group of short shafts 93 is fixed by a second bearing seat 94 and the box wall of the cleaning box 50 to play a connecting role. A sprocket 95 is sleeved on the position of the short shaft 93 on the cleaning roller 9 that extends out of the cleaning box 50.

[0066] Among them, the adjacent sprockets 95 at the same height are connected by a synchronous chain 53, and the short shafts 93 of the upper and lower cleaning rollers 9 are also sleeved with synchronous gears 54 (only one set in each row), and the two sets of synchronous gears 54 are meshed up and down. Figure 10-11 shown.

[0067] Among them, one set of short shafts 93 extends outward and is connected to the uniform speed motor 55 through a coupling for transmission. The uniform speed motor 55 is fixed by a bracket and the outer wall of the cleaning box 50, such as Figure 10-11 shown.

[0068] The cleaning box 50 is provided with a dust-cleaning fan for acting on the cleaning roller 9. The dust-cleaning fan regularly cleans the wiping cloth 92 on the cleaning roller 9. The left end surface of the cleaning box 50 is symmetrically provided with dust discharge ports 78 above and below the feeding window 77. The dust during cleaning is discharged outward from the dust discharge ports 78 and collected in time. Fig.10 shown.

[0069] Furthermore, a cooling water tank 70 (with a built-in refrigerator) is installed on the outer side of the base 1, and an inner chamber for installing the cooling water tank 70 is opened on the outer side of the base 1. The cooling water tank 70 is connected to the first joint 73 on the heat sink 60 through an inlet pipe group 71, and the cooling water tank 70 is connected to the second joint 74 on the heat sink 60 through a return pipe group 72. The inlet pipe group 71 and the return pipe group 72 both include corrugated expansion pipes, and a spiral cooling pipe 75 (spirally arranged) is arranged inside the heat sink 60, and the upper and lower ends of the spiral cooling pipe 75 are respectively connected to the first joint 73 and the second joint 74.

[0070] When the present embodiment is in use, the handle 39 is first pulled to pull the pressing plate 37 upward, and several groups of ceramic plates 34 are stacked in sequence from the feeding window 77 and placed in the arrangement storage chamber 33 (the bottom group of ceramic plates 34 is just in the discharge channel 32). At this time, the servo motor 22 is started to drive the small gear 21 to rotate, and the large gear 20 is caused to rotate slowly through meshing deceleration, causing the driving roller 12 to make a circular motion. When the driving roller 12 moves, the rotary slide groove 19 and the slider 18 interact with each other, causing the push rod 16 to move linearly to the right in the movable push rod groove 15, pushing the ceramic plate 34 in the discharge channel 32, so that the ceramic plate 34 leaves the discharge channel 32 and slides into the punching fixture seat 76 until it stops moving after encountering the resistance of the blocking block 84, and the ceramic plate 34 is accurately positioned.

[0071] At this time, the fiber laser 6 is started to generate a laser beam, which is highly focused through the internal optical system to form a very small light spot. The focusing laser head 7 concentrates the energy, and the ceramic plate 34 below absorbs the laser energy, causing the local temperature to rise rapidly. The high temperature causes the material to undergo a phase change from solid to liquid or even gas, forming holes. Through the displacement coordination of the X-axis motion seat 3 and the Y-axis motion seat 5, the focusing laser head 7 is moved to different positions of the ceramic plate 34 for laser drilling. At the same time, the cooling water in the cooling water tank 70 is pumped into the water inlet pipe group 71, flows in the pipe and enters the spiral cooling pipe 75 on the inner side of the heat sink 60. When the cooling water flows in the spiral cooling pipe 75, it takes away the heat generated by the fiber laser 6 due to work. Then the cooling water returns to the cooling water tank 70 through the reflux pipe group 72 for refrigeration, and the cycle continues.

[0072] When the punching operation of the ceramic plate 34 is completed, the push rod 16 continues to push the ceramic plate 34 to move linearly to the right, and the ceramic plate 34 and the arc surface 86 of the stop block 84 are squeezed against each other, causing the two groups of stop blocks 84 to rise, and the ceramic plate 34 passes through the positioner 8 and enters the interior of the cleaning box 50 through the feed port 51. At this time, the push rod 16 makes a return movement to the left driven by the drive roller 12, and the push rod 16 leaves the discharge channel 32. Under the pressure of the pressure plate 37, a group of ceramic plates 34 arranged at the bottom layer in the storage cavity 33 are automatically replenished and enter the discharge channel 32.

[0073] The ceramic plate 34 entering the cleaning box 50 extends into the moving gap 52. At this time, the uniform speed motor 55 is started to drive one group of cleaning rollers 9 to rotate at a uniform speed, and through the upper and lower meshing of the synchronous gear 54, the other group of cleaning rollers 9 directly above are made to move in the opposite direction. At the same time, the two groups of cleaning rollers 9 are driven by the sprocket 95 and the synchronous chain 53 to make the upper and lower rows of cleaning roller structures move synchronously in the same direction. The cleaning rollers 9 wipe the upper and lower surfaces of the ceramic plate 34 with the moving wiping cloth 92. At the same time, there is a friction force between the upper and lower groups of cleaning rollers 9 and the upper and lower surfaces of the ceramic plate 34, causing the ceramic plate 34 to move from left to right, thereby achieving the purpose of cleaning and transporting until it is discharged from the discharge port 56. Embodiment 2

[0074] On the basis of the first embodiment, when cooling the fiber laser 6, the existing water cooling system has poor cooling effect. In particular, when the fiber laser 6 works continuously, the fiber laser 6 and the cutting head are prone to overheating. In order to solve the above problem, an auxiliary vaporization flow channel 61 is opened in the heat sink 60. Figure 13-15 shown.

[0075] Specifically, the outer side of the auxiliary vaporization flow channel 61 is the inner shell of the fiber laser 6, forming a seal, and the bottom of the auxiliary vaporization flow channel 61 is provided with a liquid inlet 62, and the liquid inlet 62 is connected to a liquid injection pipe 63, and the liquid injection pipe 63 is L-shaped, and the liquid injection pipe 63 is connected to the condensation medium tank 65, such as Fig.14 and 15 shown.

[0076] Among them, a solenoid valve 64 is installed at the bottom of the condensing medium tank 65, which plays the role of unidirectional control of medium flow. A small booster pump 66 is arranged inside the condensing medium tank 65. The upper end of the condensing medium tank 65 is connected to a spiral condensing pipe 67, which is located on the periphery of the water inlet pipe group 71. Cooling water flows in the water inlet pipe group 71, which will cool down the surrounding area. Fig.13 and 14 shown.

[0077] The upper end of the spiral condenser tube 67 is connected to a guide tube 68, and the top of the auxiliary vaporization flow channel 61 is provided with an exhaust hole 69, and the guide tube 68 is inserted into the exhaust hole 69 at an angle downward. Fig.14 and 15 shown.

[0078] Furthermore, the condensing medium is stored in the condensing medium tank 65, and a connecting sleeve 79 is provided on the outer side of the condensing medium tank 65. The connecting sleeve 79 is sleeved on the outside of the water inlet pipe group 71 to play a role of connection and fixing. Fig.13 and 14 shown.

[0079] When the present embodiment is in use, when the fiber laser 6 is working, the small booster pump 66 in the condensing medium tank 65 is started, and the liquid condensing medium in the condensing medium tank 65 is injected into the lower position inside the auxiliary vaporization flow channel 61 through the injection pipe 63 (under the condition that the solenoid valve 64 is opened). During the flow of the liquid condensing medium in the auxiliary vaporization flow channel 61, the liquid condensing medium absorbs the heat in the fiber laser 6 and continuously vaporizes, and takes away the heat generated by the fiber laser 6 to achieve the purpose of cooling. The vaporized medium rises in the auxiliary vaporization flow channel 61 and continuously flows from the guide pipe 68 into the spiral condensing tube 67. When the spiral condensing tube 67 moves in a spiral long distance, it fully contacts the inner wall of the condensing tube (the condensing tube is located at the outer periphery of the water inlet pipe group 71, and can absorb the surrounding heat to maintain a low temperature state). The vaporized medium is re-liquefied into a liquid condensing medium and flows into the condensing medium tank 65, and the cycle is repeated.
