[0004] However, when implementing the above technical solutions, the following problems exist: when using the above device, it is necessary to regularly stop the device from drilling according to the impurity content in the used clear water, and then clean the impurities on the surface of the filter cartridge. The quality requirements for the used clear water are relatively high. And when performing large-batch glass drilling, if it is necessary to stop the laser drilling machine to clean the impurities, it will interrupt the glass drilling process and prolong the overall glass drilling process, which is not conducive to using the device for large-batch glass drilling.

[0005] Therefore, the present invention proposes a laser drilling device for glass drilling. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention proposes a laser drilling device for glass drilling, which solves the problem that the impurities on the surface of the internal filter cartridge of the existing glass laser drilling machine cooling device need to be cleaned during shutdown, and will prolong the glass drilling time when performing large-batch cleaning.

[0007] To achieve the above object, according to an embodiment of the first aspect of the present invention, a laser drilling device for glass drilling is proposed, including a water storage tank, and a cleaning mechanism is arranged inside the water storage tank. The cleaning mechanism includes:

[0008] A filter screen, the filter screen is detachably arranged inside the water storage tank, a cleaning ring is slidably connected to the surface of the filter screen, and the cleaning ring is attached to the filter screen; the cleaning ring is inclined; two shielding nets are slidably connected inside the cleaning ring through a moving component;

[0009] Two driving rings are fixedly connected to the surface of the cleaning ring. A driving column is rotatably connected inside a single driving ring. A stacking block is slidably connected inside the cleaning ring. A driving belt is fixedly connected between the stacking block and the driving column;

[0010] A cleaning box is fixedly connected inside the water storage tank. A driving shaft is fixedly connected to the surface of the cleaning box. A sealing block is slidably connected to the surface of the cleaning box; the sealing block is adapted to the stacking block.

[0011] Optionally, the moving assembly includes a resistance block slidably arranged on the surface of the cleaning ring. A moving belt is fixedly connected between the resistance block and the shielding net.

[0012] Optionally, a moving spring is fixedly connected between the shielding net and the cleaning ring. The moving spring is sleeved on the surface of the moving belt.

[0013] Optionally, a storage cavity is formed inside the cleaning ring. The shielding net is slidably arranged inside the storage cavity.

[0014] Optionally, an equipment box is fixedly connected inside the water storage tank. A water pump is fixedly connected inside the equipment box. A water inlet pipe is fixedly connected to the surface of the equipment box. The center of the water inlet pipe and the center of the filter net are located on the same vertical line. A propeller is rotatably connected inside the water inlet pipe.

[0015] Optionally, a moving rod is rotatably connected inside the water storage tank. A transmission assembly is arranged between the driving ring far from the cleaning box and the moving rod. A transmission assembly is arranged between the driving shaft and the driving column.

[0016] Optionally, the transmission assembly includes a moving shaft fixedly arranged inside the driving ring. A spiral groove is formed on the surface of the moving rod. The moving shaft is adapted to the spiral groove.

[0017] Optionally, the length of the spiral groove on the surface of the moving rod is less than the height of the filter net; and the spiral groove on the surface of the moving rod is an annular groove.

[0034] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0035] As Figures 1-7 shown, a laser drilling device for glass drilling includes a water storage tank 1. A cleaning mechanism is arranged inside the water storage tank 1. The cleaning mechanism includes:

[0036] A filter screen 21, which is detachably arranged inside the water storage tank 1. A cleaning ring 22 is slidably connected to the surface of the filter screen 21. The cross-section of the cleaning ring 22 is an isosceles trapezoid, and the longest side is attached to the filter screen 21; the cleaning ring 22 is inclined;

[0037] Two shielding nets 23, both of which are slidably connected to the inside of the cleaning ring 22, and the two shielding nets 23 are symmetrically arranged. The shielding nets 23 are parallel to the non-parallel sides of the cleaning ring 22; a storage cavity is formed on the surface of the cleaning ring 22; the shielding nets 23 are slidably arranged inside the storage cavity;

[0038] It should be noted that the shielding net 23 is relatively dense, and the amount of water passing through the shielding net 23 in a short time is small;

[0039] A moving component, which is arranged on the side of the shielding net 23 away from the filter screen 21;

[0040] Two driving rings 24, both of which are fixedly connected to the cleaning ring 22 and are arranged symmetrically in a staggered manner. A driving column 25 is rotatably connected to the inside of the lower driving ring 24. An accumulation block 26 is slidably connected to the inside of the cleaning ring 22. A driving belt 27 is fixedly connected between the accumulation block 26 and the driving column 25;

[0041] Cleaning box, the cleaning box is fixedly arranged inside the water storage tank 1, a driving shaft 28 is fixedly connected to the surface of the cleaning box, and a transmission component is arranged between the driving shaft 28 and the driving column 25; a sealing block 29 is slidably connected to the surface of the cleaning box; a clamping groove is formed on the surface of the sealing block 29, and the clamping groove is adapted to the accumulation block 26;

[0042] In the actual application process of this laser drilling equipment for glass drilling, by arranging an inclined cleaning ring 22 and a cleaning box inside the water storage tank 1, the lower part of the cleaning ring 22 can contact the driving shaft 28 on the surface of the cleaning box. The contact between the driving shaft 28 and the driving column 25 can promote the movement of the driving belt 27, thereby driving the movement of the accumulation block 26. The impurities inside the storage cavity can slide into the cleaning box autonomously under the action of gravity. Then, when the cleaning ring 22 moves to a certain position, the impurities concentrated at a certain position inside due to gravity will move again under the action of gravity and enter the cleaning box. And under the action of a small amount of water, the impurities will be directly discharged along the cleaning box, which can ensure that when the laser drilling equipment is used, the impurity content in its cooling water is relatively low, avoiding affecting the cooling effect. And the impurities blocked by the filter net 21 will be intermittently discharged after being cleaned, without the need for separate operation, which is more convenient;

[0043] In some specific implementation schemes, the moving component includes a resistance block 31 slidably arranged on the surface of the cleaning ring 22. A moving belt 32 is fixedly connected between the resistance block 31 and the shielding net 23. A moving spring 33 is fixedly connected between the shielding net 23 and the cleaning ring 22. The moving spring 33 is sleeved on the surface of the moving belt 32. When the moving spring 33 is in a natural state, the end of the shielding net 23 away from the moving belt 32 contacts the cleaning ring 22; by the resistance block 31 slidably arranged on the surface of the cleaning ring 22, during the movement of the resistance block 31, due to the condition that the resistance block 31 has no power, etc., the resistance block 31 will lag behind the cleaning ring 22, and then the distance between the resistance block 31 and the cleaning ring 22 will increase. At this time, through the moving belt 32, the shielding net 23 moves, and one end disengages from the cleaning ring 22, and this position of the cleaning ring 22 is in an open state, and the lifted impurities enter the storage cavity;

[0044] In some specific implementation schemes, an equipment box is fixedly connected inside the water storage tank 1. A water pump (not shown in the figure) is fixedly connected inside the equipment box. An inlet pipe is fixedly connected to the surface of the equipment box. The center of the inlet pipe and the center of the filter net 21 are located on the same vertical line. A propeller 41 is rotatably connected inside the inlet pipe; for the propeller located at the inlet pipe position, when the water pump pumps water out of the water storage tank 1, it will rotate under the action of water, and then part of the force of the water flow can be converted into power;

[0045] In a further embodiment, a moving rod 42 is rotatably connected inside the water storage tank 1. A transmission assembly is provided between the driving ring 24 away from the cleaning box and the moving rod 42, and a transmission assembly is provided between the driving shaft 28 and the driving column 25. The transmission assembly includes a moving shaft 43 fixedly arranged inside the driving ring 24. A spiral groove 44 is formed on the surface of the moving rod 42. The spiral groove 44 is an annular groove, and the moving shaft 43 is adapted to the spiral groove 44;

[0046] The length of the spiral groove 44 located on the surface of the moving rod 42 is less than the height of the filter screen 21; Synchronous wheels are fixedly connected to the surfaces of the moving rod 42 and the propeller 41, and a synchronous belt is connected between the synchronous wheels in a transmission manner; Through the moving rod 42, the synchronous wheels and the synchronous belt, the rotation of the propeller 41 can be converted into the rotation of the moving rod 42, thereby causing the driving ring 24 to reciprocate. With the power provided by the water pump, the reciprocating movement of the cleaning ring 22 is realized. There are few control components and it is easy to operate; And the water circulation speed can be directly adjusted according to the working state of the laser drilling machine. At the same time, the water flow rate directly affects the reciprocating speed of the cleaning ring 22, ensuring that the impurities left by the water passing through the filter screen 21 will not stay for a long time, avoiding affecting the water flow rate entering the water inlet pipe; And the flow rate is directly related to the cleaning speed, without manual adjustment, which is convenient to use;

[0047] In some specific embodiments, a water inlet is formed on the surface of the water storage tank 1, and the height of the water inlet is higher than the height of the propeller 41; A return pipe is fixedly connected to the surface of the water storage tank 1, and the height of the return pipe is lower than the height of the propeller 41;

[0048] It should be noted that both the water inlet pipe and the return pipe are fixedly connected to the laser emitter of the laser drilling equipment in a position-communication manner, and the water flow inside the water inlet pipe and the return pipe surrounds this area for local cooling;

[0049] Ensure that the water source inside the water storage tank 1 can be higher than the position of the water inlet pipe to ensure smooth water intake; And the height of the return pipe is lower than that of the water inlet pipe, so that the water with increased temperature directly enters the bottom of the water storage tank 1 and conducts heat transfer with the water at a higher position, avoiding directly entering the water inlet pipe again and affecting the cooling effect;

[0050] In some specific embodiments, a sealing cover is rotatably connected to the surface of the water storage tank 1, and a sealing strip is provided between the sealing cover and the water storage tank 1; Through the design of the water storage tank 1 that can be opened, and the water storage tank 1 can be directly opened after long-term non-use or long-term use, which is convenient for cleaning the inside of the water storage tank 1;

[0051] In some specific embodiments, two connecting rings 51 are fixedly connected inside the water storage tank 1. A connecting groove 52 is formed on the surface of the connecting ring 51. The cross-section of the connecting groove 52 is in the shape of "6", and the width of the connecting groove 52 is the same as the width of the filter screen 21. The two connecting rings 51 are symmetrically arranged with respect to the filter screen 21. The extension line of the protruding position of the connecting groove 52 is perpendicular to the sealing cover, and the cleaning box is attached to the connecting ring 51. Through the connecting ring 51 and the connecting groove 52, the sheet-shaped filter screen 21 can be directly placed in. After the filter screen 21 is placed in, it will form a cylindrical shape, which is convenient for subsequent replacement and disassembly of the filter screen 21.

[0052] The working principle of the present invention:

[0053] When the laser drilling equipment is in use, first, an appropriate amount of water is poured into the water storage tank 1 from the water inlet, and then the water pump is started. The water pump causes the water inside the water storage tank 1 to flow through the filter screen 21 and into the water inlet pipe. The water flow causes the propeller 41 inside the water inlet pipe to rotate. Through the synchronous pulley and the synchronous belt, the rotation of the propeller 41 drives the moving rod 42 to rotate, thereby causing the driving ring 24 to drive the cleaning ring 22 to slide back and forth on the surface of the filter screen 21. When the cleaning ring 22 moves, the resistance block 31 pulls the shielding net 23, causing the impurities on the surface of the filter screen 21 to flow into the storage cavity. When the cleaning ring 22 slides to the position where the driving column 25 contacts the driving shaft 28, the movement of the cleaning ring 22 causes the driving column 25 to rotate. Through the driving belt 27, the stacking block 26 is pulled, and at the same time, the stacking block 26 drives the sealing block 29 to move, so that the impurities flow into the cleaning box. When the cleaning ring 22 moves again and the driving column 25 and the driving shaft 28 are separated, the stacking block 26 and the sealing block 29 return to their original positions.

[0054] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
