Description

Technical Field

[0001] This utility model relates to the field of glass substrate processing, specifically a protective device for glass substrate grinding processing. Background Technology

[0002] In the precision machining of glass substrates, grinding is a crucial process to ensure dimensional accuracy and edge quality. Existing grinding machines are typically equipped with coarse grinding wheels, fine grinding wheels, and a third-axis grinding wheel for chamfering or finishing. During edge grinding, coolant is continuously sprayed to cool, lubricate, and flush away grinding debris, generating a large amount of wastewater and grinding debris. If this wastewater is not removed promptly and effectively, it will splash and re-adhere to the ground glass substrate surface, causing watermarks, stains, and even scratches due to residual grinding debris, severely affecting product cleanliness and yield.

[0003] Currently, the common practice in the industry is to install simple baffles or water collection tanks near the grinding wheel. However, this method has obvious drawbacks: its sealing performance is poor, it cannot completely prevent the fine splashing of wastewater, the wastewater discharge efficiency is low, and it is easy for wastewater to accumulate and drip inside the enclosure, causing secondary pollution. Utility Model Content

[0005] To achieve the above objectives, a protective device for glass substrate grinding is provided, including a water-absorbing protective box. The front of the water-absorbing protective box is provided with a negative pressure cover, and an adsorption cover is fixed on the negative pressure cover. At the same time, a grinding wheel is provided inside the adsorption cover. The back of the water-absorbing protective box is respectively equipped with a primary negative pressure mechanism, a secondary negative pressure mechanism and a tertiary negative pressure mechanism.

[0006] Furthermore, the interior of the water-absorbing protective box is provided with a collection trough, which is rectangular in shape. Three sets of branch pipes are equidistantly provided on one side of the collection trough, and a primary negative pressure mechanism, a secondary negative pressure mechanism, and a tertiary negative pressure mechanism are respectively installed on the three sets of branch pipes. The inner diameter of the adsorption cover is larger than the diameter of the grinding wheel.

[0007] Furthermore, the structures of the primary negative pressure mechanism, the secondary negative pressure mechanism, and the tertiary negative pressure mechanism are identical. The tertiary negative pressure mechanism includes a negative pressure pipe inserted into the branch pipe opening, and the end of the negative pressure pipe is provided with a connecting pipe.

[0008] Furthermore, an air volume regulating valve is connected to the connecting pipe via a flange, and a fan suction pipe is provided on one side of the air volume regulating valve. The primary negative pressure mechanism, the secondary negative pressure mechanism, and the tertiary negative pressure mechanism are distributed in parallel.

[0009] Furthermore, an inner frame is fixed to the end of the negative pressure cover, and the inner frame is inserted into the inside of the branch pipe opening. The inner frame is rectangular.

[0010] Furthermore, a sealing gasket is provided between the inner frame and the inner wall of the branch pipe opening, and the inner frame and the branch pipe opening are sealed together by the sealing gasket.

[0011] Furthermore, the negative pressure cover is screwed onto the front of the water absorption protection box, and the negative pressure cover and the water absorption protection box are sealed together by a sealing gasket.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: through the cooperation of the three-stage parallel negative pressure mechanism with the collection tank and adsorption hood, the impurities such as cooling water generated by the grinding wheel are efficiently and comprehensively adsorbed. A sealing gasket is designed between the rectangular collection tank and the rectangular inner frame to improve the sealing performance of the negative pressure transmission.

Detailed Implementation

[0020] Please see Figure 1 - Figure 6 This utility model provides a protective device for glass substrate grinding and processing, including a water-absorbing protective box 100. The front of the water-absorbing protective box 100 is provided with a negative pressure cover 200, and an adsorption cover 22 is fixed on the negative pressure cover 200. At the same time, a grinding wheel 600 is provided inside the adsorption cover 22. The back of the water-absorbing protective box 100 is respectively equipped with a first-level negative pressure mechanism 300, a second-level negative pressure mechanism 400 and a third-level negative pressure mechanism 500.

[0021] In a preferred embodiment, the water absorption and protection box 100 has an internal collection groove 11, which is rectangular. Three sets of branch pipe ports 12 are equidistantly provided on one side of the collection groove 11. A primary negative pressure mechanism 300, a secondary negative pressure mechanism 400, and a tertiary negative pressure mechanism 500 are respectively installed on the three sets of branch pipe ports 12. The inner diameter of the adsorption cover 22 is larger than the diameter of the grinding wheel 600.

[0022] The first-level negative pressure mechanism 300, the second-level negative pressure mechanism 400 and the third-level negative pressure mechanism 500 have the same structure. The third-level negative pressure mechanism 500 includes a negative pressure pipe 51 inserted into the branch pipe port 12, and the end of the negative pressure pipe 51 is provided with a connecting pipe 52.

[0023] A flow rate regulating valve 53 is connected to the connecting pipe 52 via a flange, and a fan suction pipe 54 is provided on one side of the flow rate regulating valve 53. The first-stage negative pressure mechanism 300, the second-stage negative pressure mechanism 400 and the third-stage negative pressure mechanism 500 are distributed in parallel.

[0024] The negative pressure cover 200 has an inner frame 21 fixed at its end, and the inner frame 21 is inserted into the inside of the branch pipe port 12. The inner frame 21 is rectangular.

[0025] Working principle: During use, the primary negative pressure mechanism 300, the secondary negative pressure mechanism 400, and the tertiary negative pressure mechanism 500 are activated simultaneously. Each mechanism connects to three sets of branch pipe ports 12 on one side of the collection tank 11 inside the suction protection box 100 via its respective negative pressure pipe 51. Combined with the mounting structure where the rectangular inner frame 21 fixed to the end of the negative pressure cover 200 is inserted into the branch pipe ports 12, a stable negative pressure environment is formed by the adsorption cover 22 fixed on the negative pressure cover 200. Because the inner diameter of the adsorption cover 22 is larger than the diameter of the grinding wheel 600, the dust, debris, and cooling liquid generated by the grinding wheel 600 during operation are efficiently captured by the adsorption cover 22. Subsequently, impurities enter the collection tank 100 through the negative pressure cover 200. 1. Then, through three sets of branch pipes 12, the air flows into the negative pressure pipes 51 of the corresponding primary negative pressure mechanism 300, secondary negative pressure mechanism 400 and tertiary negative pressure mechanism 500 respectively. The air is then transported to the air volume regulating valve 53 through the connecting pipe 52. The operator can control the adsorption air volume of each negative pressure mechanism by adjusting the air volume regulating valve 53 to ensure that the adsorption effect is adapted to the grinding operation requirements. Finally, the impurities are discharged or collected through the fan adsorption pipe 54. The fan adsorption pipe 54 is connected to the external negative pressure fan pump. The primary negative pressure mechanism 300, secondary negative pressure mechanism 400 and tertiary negative pressure mechanism 500 are arranged in parallel to ensure the overall suction stability of the adsorption system and avoid the failure of a single mechanism from affecting the overall protection effect.

[0026] Through the cooperation of the three-stage parallel negative pressure mechanism with the collection tank 11 and the adsorption hood 22, the system can efficiently and comprehensively adsorb impurities such as cooling water generated by the grinding wheel 600. A sealing gasket 23 is designed between the rectangular collection tank 11 and the rectangular inner frame 21 to improve the sealing performance of the negative pressure transmission. The air volume regulating valve 53 can flexibly adjust the adsorption intensity, which can effectively prevent the spread of dust and liquid impurities and pollute the environment, protect the health of operators, and ensure the cleanliness and safety of the grinding operation. The parallel distribution of the negative pressure mechanism also enhances the reliability and adaptability of the system; it can prevent wastewater splashing, improve wastewater discharge efficiency, and avoid secondary pollution.

[0027] When the external switch of the external negative pressure fan is activated, a negative pressure is created inside the water suction protection box 100 and the adsorption hood 22, which can adsorb water vapor and waste debris. The number of primary negative pressure mechanisms 300, secondary negative pressure mechanisms 400, and tertiary negative pressure mechanisms 500 can be selected according to the actual situation, for example:

[0028] When the glass substrate undergoes a rough grinding process, all three negative pressure mechanisms—the first-level negative pressure mechanism 300, the second-level negative pressure mechanism 400, and the third-level negative pressure mechanism 500—are activated to enable the water absorption protection box 100 to enter the maximum suction mode.

[0029] For fine grinding processes, activate the primary negative pressure mechanism 300 and the secondary negative pressure mechanism 400 to enter the medium suction mode.

[0030] If it is a fine grinding or standby process, only the first-level negative pressure mechanism 300 is turned on for use, and the minimum suction mode is entered.

[0031] In a preferred embodiment, a sealing gasket 23 is provided between the inner frame 21 and the inner wall of the branch pipe opening 12, and the inner frame 21 and the branch pipe opening 12 are sealed together by the sealing gasket 23.

[0032] The negative pressure cover 200 is screwed onto the front of the water absorption protection box 100, and the negative pressure cover 200 and the water absorption protection box 100 are sealed together by a sealing gasket 23.

[0033] like Figure 4 - Figure 6 As shown: The inner frame 21 and the branch pipe port 12 are sealed together by a sealing gasket 23. At the same time, the negative pressure cover 200 is screwed to the front of the water absorption protection box 100 and the two are also sealed together by a sealing gasket 23. This can significantly improve the sealing performance of the entire adsorption system, effectively prevent air leakage at the connection between the negative pressure cover 200, the inner frame 21 and the branch pipe port 12 of the water absorption protection box 100, and ensure that the negative pressure environment generated by the first-stage negative pressure mechanism 300, the second-stage negative pressure mechanism 400 and the third-stage negative pressure mechanism 500 is stable and concentrated. This ensures that the adsorption efficiency of the adsorption cover 22 for dust, debris and liquid impurities generated by the grinding wheel 600 is not reduced, while reducing environmental pollution caused by impurities seeping from the connection and reducing the increase in energy consumption caused by air leakage of the negative pressure mechanism. The connection method of screwing together with the sealing gasket 23 also facilitates the subsequent disassembly, replacement and maintenance of the negative pressure cover 200, the inner frame 21 and the sealing gasket 23, further improving the ease of use and durability of the equipment.
