Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal glass substrate manufacturing, and specifically relates to a cooling water device for grinding wheel processing. Background Art

[0002] In the precision manufacturing process of liquid crystal glass substrates, edge grinding is a key step to ensure product quality and appearance consistency. This process usually uses a grinding wheel equipped with multiple grinding grooves to finely process the glass edge. The design of multiple grinding grooves aims to extend the service life of the grinding wheel. By using it layer by layer, when a certain layer of grinding groove is severely worn due to long-term use, it can be switched to other layers to continue the operation. However, this design faces a series of challenges in practical applications.

[0003] Firstly, the high heat generated during the grinding process is inevitable. Especially during high-speed and efficient edge grinding operations, the friction between the grinding wheel and the glass edge will generate a large amount of heat energy. If not dissipated in time, it will not only accelerate the wear of the grinding wheel, but also may cause thermal stress deformation of the glass substrate, affecting the quality of the finished product. Therefore, setting a water spraying and cooling structure near the grinding wheel has become a common solution. However, whenever the grinding groove is switched, due to the change in the position of the grinding groove, the original water spraying angle often cannot accurately align with the new edge grinding part, resulting in a significant reduction in the cooling effect. To restore the effective cooling effect, operators have to manually adjust the water spraying angle of the water spraying and cooling structure. This process is not only time-consuming and laborious, increasing the manual intervention and downtime of the production line, but also has certain safety hazards due to environmental factors such as high temperature and wetness.

[0004] In addition, the accumulation of glass powder residues in the grinding groove during the edge grinding process is also an urgent problem to be solved. As the grinding operation continues, fine glass powder residues will gradually fill the grinding groove. If not cleaned in time, it will not only affect the cutting efficiency and accuracy of the grinding wheel, but also form scratches or pits during the grinding process, seriously damaging the edge quality of the glass substrate. Traditional methods often rely on regular shutdown cleaning, which not only reduces production efficiency, but also may leave quality hidden dangers due to incomplete cleaning.

[0005] In summary, we propose a cooling water device for grinding wheel processing. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, 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 utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] Please refer to Figure 1-7 , the present utility model provides a technical solution: a cooling water device for grinding wheel processing, mainly composed of a lifting and carrying mechanism 1, a driving motor 2, a grinding wheel 3, a sewage collection tank 4, a cooling mechanism 5, and a cleaning mechanism 6;

[0032] Among them, the lifting and carrying mechanism 1 takes the base 11 as a carrier. A support frame 12 is connected to the upper part of the base 11, and a hydraulic cylinder 13 is installed on one side of the upper part of the base 11 within the support frame 12. The telescopic end of the hydraulic cylinder 13 is rotatably connected to a roller 14. A pulling belt 15 is arranged outside the roller 14. An elevating seat 16 that can be lifted is arranged above the base 11. One end of the pulling belt 15 is connected to the base 11, and the other end is connected to the elevating seat 16. A plurality of guide wheels 17 are installed on both sides of the elevating seat 16. The guide wheels 17 roll inside the support frame 12. When it is necessary to change the height of the elevating seat 16, by controlling the telescopic movement of the hydraulic cylinder 13, taking elevation as an example, the hydraulic cylinder 13 extends, pushing the roller 14 upward. Since one end of the pulling belt 15 is connected to the base 11 and the other end is connected to the elevating seat 16, and the base 11 is fixed and the elevating seat 16 can move, when the roller 14 moves upward, it will push the pulling belt 15 towards the end connected to the base 11, so the other end connected to the elevating seat 16 will rise. That is to say, at this time, the pulling belt 15 will pull the elevating seat 16 upward. When lowering, the same operation can be performed;

[0033] The driving motor 2 and the grinding wheel 3 are both installed on the lifting seat 16. Specifically, the driving motor 2 is installed on the upper part of the lifting seat 16, and the driving end of the driving motor 2 extends to the lower part of the lifting seat 16 and is connected to the grinding wheel 3 through a coupling. Multiple grinding grooves 31 are provided on the surface of the grinding wheel 3. Before edging the glass 7, it needs to be placed on the workbench first, which is well-known in the art. Then, the edge of the glass 7 is moved into the interior of one of the grinding grooves 31, and then the driving motor 2 drives the grinding wheel 3 to rotate at a high speed to achieve the edging process of the glass 7. During the edging process, the water spray nozzle of the cooling mechanism 5 is aligned with the part where the edge of the glass contacts the grinding groove 31, so as to reduce the temperature generated by the friction between the glass 7 and the grinding wheel 3. When this grinding groove 31 is no longer usable, the lifting and bearing mechanism 1 will drive the lifting seat 16 to rise, so that the grinding wheel 3 rises. During the rising process, a distance measuring sensor is also provided on the device. The distance measuring sensor is installed at the bottom end of the lifting seat 16 to measure the distance between the lifting seat 16 and the base 11. For example, now it is necessary to replace the grinding groove 31 on the next layer. The distance between the center horizontal lines of each layer of grinding grooves 31 is 5 cm. Before rising, the distance measuring sensor detects that the distance between the lifting seat 16 and the base 11 is 100 cm. When the distance between the lifting seat 16 and the base 11 rises to 105 cm, it means that it has reached the grinding groove 31 on the next layer. At this time, the controller will control the hydraulic cylinder 13 to stop extending, and then move the edge of the glass 7 into this layer of grinding groove 31;

[0034] The sewage collection pool 4 is installed on the base 11. The sewage collection pool 4 can collect the cooled sewage and the cleaned sewage. A collection hopper 41 is connected to the bottom of the sewage collection pool 4, and the lowest position of the collection hopper 41 is connected to a sewage discharge pipe 42, and the sewage discharge end of the sewage discharge pipe 42 extends outwards;

[0035] The cooling mechanism 5 and the cleaning mechanism 6 are both installed on the upper part of the sewage collection pool 4, and the cooling mechanism 5 is installed obliquely. The cleaning mechanism 6 includes a guide rail 61. A slider 62 is slidably connected inside the guide rail 61. An oblong adjustment hole 63 is reserved on one side of the guide rail 61, and a threaded hole 64 is reserved on one side of the slider 62. A fastening screw 65 is connected inside the adjustment hole 63 and the threaded hole 64. The upper part of the slider 62 is connected with a fastener 66. Through holes one 67 and two 68 are respectively reserved inside the fastener 66. A support rod 69 is connected inside the through hole one 67, and a water delivery pipe 610 is connected inside the through hole two 68. The end of the support rod 69 is installed with a spray head 611. The water delivery pipe 610 is connected to the water inlet end of the spray head 611, and the water delivery pipe 610 is connected to an external water supply device. When it is necessary to clean the glass powder residue inside the grinding groove 31, water is sprayed into the grinding groove 31 through the spray head 611 for flushing. After timely cleaning, it is ensured that the glass powder residue will not affect the edging process of the glass 7;

[0036] The structure of the temperature reduction mechanism 5 includes a fastener 66, a first through hole 67, a second through hole 68, a support rod 69, a water delivery pipe 610, and a nozzle 611. Its principle is the same as the part of the water spraying and flushing of the cleaning mechanism 6, which will not be elaborated here.
