Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, specifically to a cutting fluid collection and filtration mechanism for a silicon component processing machine tool. Background Technology

[0002] Silicon component processing machine tools are specialized mechanical equipment used to process silicon materials (such as monocrystalline silicon, polycrystalline silicon, and silicon nitride ceramics). They are mainly used to perform processes such as grinding, polishing, and cutting of silicon rods to ensure that the dimensional accuracy, surface roughness, and shape tolerances of silicon components meet the requirements of the semiconductor or photovoltaic industries. They are mainly used in the photovoltaic industry (such as silicon rod squaring, grinding, polishing, and slicing) and the semiconductor industry (such as precision machining of silicon nitride ceramics).

[0003] When silicon components are milled and ground on a silicon component processing machine tool, cutting fluid is sprayed onto the surface of the silicon component and the tool position during the cutting process to reduce the heat generated between the tool and the silicon component and to flush away the chips and impurities generated during the process. This achieves the effects of cooling, cleaning and chip removal. In order to improve the reuse rate of cutting fluid, the cutting fluid discharged into the cutting fluid tank is filtered through a filter screen to remove impurities. The filtered cutting fluid is then transported to the machine tool for recycling. This prevents chips and silicon powder from clogging the spray system and prevents cutting fluid containing silicon powder from damaging the surface of the silicon component.

[0004] Although traditional cutting fluid tanks use filters with small pore sizes to effectively filter silicon powder, when chips are discharged onto the filter with the cutting fluid, the volume of the chips is larger than the pore size of the filter. This can accelerate the clogging of the filter, making it difficult to separate chips and silicon powder for filtration. Frequent cleaning of the filter is required, making it inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to address the deficiencies and shortcomings of existing technologies by providing a cutting fluid collection and filtration mechanism for silicon component processing machine tools.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cutting fluid collection and filtration mechanism for a silicon component processing machine tool, comprising a base located below a drain outlet, a drain trough disposed at the upper end of the base, a filter device disposed on the drain trough for filtering impurities in the cutting fluid, a collection opening disposed on the base for collecting the cutting fluid filtered by the filter device, and a discharge outlet disposed on the collection opening and connected to the machine tool. The collection opening is connected to the drain trough. The filter device includes an upper filter screen disposed on the drain trough for filtering chips in the cutting fluid, and a lower filter element disposed on the drain trough below the upper filter screen for filtering silicon powder in the chip fluid after the chips are filtered by the upper filter screen.

[0007] A further improvement is that the lower filter element includes a lower filter screen disposed on the drain tank below the upper filter screen, and a filter cotton layer disposed on the upper end face of the lower filter screen for filtering silicon powder in the cutting fluid. The lower filter screen is used to support the filter cotton layer and, after the filter cotton layer filters the silicon powder in the cutting fluid, the cutting fluid is allowed to enter the collection opening.

[0008] A further improvement is that the inner wall of the drainage tank is an inclined inner wall, the area of ​​the upper filter screen is larger than the area of ​​the lower filter screen, and the upper and lower filter screens are fitted with the inner wall of the drainage tank with clearance.

[0009] A further improvement is that a connecting mechanism is provided between the upper filter screen and the lower filter screen and the drain tank for removing or installing the upper filter screen and the lower filter screen from the drain tank.

[0010] A further improvement is that the connecting mechanism includes connecting frame plates respectively disposed on the upper filter screen and the lower filter screen, and the outer wall of the connecting frame plate is an inclined outer wall.

[0011] A further improvement is that the upper and lower filter screens are provided with a lifting handle on their upper end surfaces, and the filter cotton layer is provided with a clearance perforation for the lifting handle to pass through.

[0012] A further improvement is that the lifting handle is positioned at the midpoint between the upper and lower filter screens.

[0013] A further improvement is that the lifting handles are symmetrically arranged at the left and right ends of the upper and lower filter screens.

[0014] A further improvement is that the upper end face of the base is provided with an inclined conical groove, which is connected to the collection opening, and the outer wall of the draining tank is provided with an inclined outer wall for clearance matching with the inclined conical groove.

[0015] A further improvement is that the outer wall of the drainage tank is symmetrically provided with two handle ends.

[0016] A further improvement is that a conveyor wheel is provided on the lower end face of the base.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the chips are discharged into the drain tank along with the cutting fluid, the cutting fluid first comes into contact with the upper filter screen. The upper filter screen filters the chips in the cutting fluid. However, silicon powder remains in the cutting fluid after passing through the upper filter screen. At this time, the silicon powder in the cutting fluid is filtered through the lower filter element, so that the filtered cutting fluid enters the collection opening. The chips and silicon powder are filtered separately by the upper filter screen and the lower filter element, which can reduce the clogging speed of the filter screen. Compared with traditional filtration devices, there is no need to clean the filter screen frequently, making it more convenient to use.

[0018] Further benefits: The inclined inner wall of the drain tank facilitates the installation and removal of the upper and lower filters within the tank. When cleaning the filter cotton layer is required, first remove the upper filter upwards, then remove the filter cotton layer from the lower filter for cleaning or replacement. Alternatively, the entire lower filter can be removed, thus improving the filtration effect on silica powder. For installation, first place the lower filter in the drain tank. The inclined inner wall allows the lower filter to reach a certain position and stop descending, securing it within the tank. Then, place the filter cotton on top of the lower filter, and finally place the upper filter in the drain tank. Again, the inclined inner wall allows the upper filter to reach a certain position and stop descending. Because the area of ​​the upper filter is larger than that of the lower filter, the upper filter will remain above the lower filter after installation.

[0019] Further benefits: Compared to directly placing the upper and lower filters into the drain tank for assembly and disassembly, the connecting frame increases the contact area with the inner wall of the drain tank. This reduces the likelihood of the upper and lower filters tilting in the drain tank, thus improving their stability.

[0020] Further benefits: The pull handle design makes it easy to remove the upper and lower filters from the drain tank by hand.

[0021] Further benefits: By using the inclined conical groove in conjunction with the inclined outer wall, the drain trough can be removed from the base when changing the cutting fluid, allowing for the cleaning of residual cutting fluid in the collection opening and reducing the residue of old cutting fluid.

[0022] Further benefits: The addition of conveyor wheels facilitates the movement of the base, allowing it to be pushed to a specific location during cleaning or maintenance. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] See Figures 1 to 5 As shown, the technical solution adopted in this specific embodiment is: a cutting fluid collection and filtration mechanism for a silicon component processing machine tool, including a base 1 located below the drain port, a drain trough 2 located at the upper end of the base 1, a filter device located on the drain trough 2 for filtering impurities in the cutting fluid, a collection opening 3 located on the base 1 for collecting the cutting fluid filtered by the filter device, and a drain port 4 located on the collection opening 3 and connected to the machine tool. The collection opening 3 is connected to the drain trough 2. The filter device includes an upper filter screen 5 located on the drain trough 2 for filtering chips in the cutting fluid, and a lower filter element located on the drain trough 2 below the upper filter screen 5 for filtering silicon powder in the chip fluid after the upper filter screen 5 filters the chips.

[0028] The lower filter element includes a lower filter screen 6 disposed on the drain tank 2 below the upper filter screen 5, and a filter cotton layer 7 disposed on the upper end surface of the lower filter screen 6 for filtering silicon powder in the cutting fluid. The lower filter screen 6 supports the filter cotton layer 7, and after the filter cotton layer 7 filters the silicon powder in the cutting fluid, the cutting fluid is allowed to enter the collection opening 3. The filter cotton layer 7 is made of polyester fiber cotton or activated carbon cotton, and the thickness of the filter surface layer is 8mm-20mm.

[0029] The inner wall of the drainage tank 2 is an inclined inner wall, the area of ​​the upper filter screen 5 is larger than the area of ​​the lower filter screen 6, and the upper filter screen 5 and the lower filter screen 6 are fitted with the inner wall of the drainage tank 2 with a clearance.

[0030] A connecting mechanism is provided between the upper filter screen 5, the lower filter screen 6, and the drain tank 2 for removing or installing the upper filter screen 5 and the lower filter screen 6 from the drain tank 2.

[0031] The connecting mechanism includes a connecting frame plate 8 respectively disposed on the upper filter screen 5 and the lower filter screen 6, and the outer wall of the connecting frame plate 8 is an inclined outer wall 16.

[0032] The upper filter screen 5 and the lower filter screen 6 are provided with a lifting handle 10 on their upper end surfaces, and the filter cotton layer 7 is provided with a clearance perforation 11 for the lifting handle 10 to pass through.

[0033] The lifting handle 10 is located at the middle position between the upper filter screen 5 and the lower filter screen 6.

[0034] The lifting handles 10 are symmetrically arranged at the left and right ends of the upper filter screen 5 and the lower filter screen 6.

[0035] The upper end face of the base 1 is provided with an inclined conical groove 15, which is connected to the collection opening 3. The outer wall of the drainage tank 2 is provided with an inclined outer wall 16 for clearance matching with the inclined conical groove 15.

[0036] The outer wall of the drainage tank 2 is symmetrically provided with two handle ends 12.

[0037] The lower end face of the base 1 is provided with a conveyor wheel 14.

[0038] The working principle of this utility model is as follows: When the chips are discharged into the drain tank 2 along with the cutting fluid, the cutting fluid first comes into contact with the upper filter screen 5. The upper filter screen 5 filters the chips in the cutting fluid. However, silicon powder remains in the cutting fluid after passing through the upper filter screen 5. At this time, the silicon powder in the cutting fluid is filtered through the filter cotton layer 7, so that the filtered cutting fluid enters the collection opening 3. The chips and silicon powder are filtered separately by the upper filter screen 5 and the lower filter element, which can reduce the clogging speed of the filter screen. Compared with traditional filtration devices, there is no need to clean the filter screen frequently, making it more convenient to use.

[0039] The inclined inner wall of the drain trough 2 facilitates the installation and removal of the upper filter screen 5 and the lower filter screen 6 within the drain trough 2. When cleaning the filter cotton layer 7 is required, first remove the upper filter screen 5 upwards, then remove the filter cotton layer 7 from the lower filter screen 6 for cleaning or replacement. Alternatively, the lower filter screen 6 can be removed entirely, thereby improving the filtration effect on silicon powder. When installation is required, first place the lower filter screen 6 into the drain trough 2. The inclined inner wall allows the lower filter screen 6 to reach a certain position and stop descending, thus securing it within the drain trough 2. Then, lay the filter cotton on the upper surface of the lower filter screen 6, and then place the upper filter screen 5 into the drain trough 2. The inclined inner wall allows the upper filter screen 5 to reach a certain position and stop descending. Since the area of ​​the upper filter screen 5 is larger than that of the lower filter screen 6, the upper filter screen 5 will remain above the lower filter screen 6 after installation.

[0040] Compared to directly placing the upper filter screen 5 and the lower filter screen 6 into the drain tank 2 for assembly and disassembly, the connection frame plate 8 increases the contact area with the inner wall of the drain tank 2. This reduces the occurrence of tilting of the upper filter screen 5 and the lower filter screen 6 in the drain tank 2, thereby improving the stability of the upper filter screen 5 and the lower filter screen 6 in the drain tank 2.

[0041] The lifting handle 10 is designed to facilitate the removal of the upper filter screen 5 and the lower filter screen 6 from the drain tank 2 by hand.

[0042] By using the inclined conical groove 15 and the inclined outer wall 16, the drain trough 2 can be removed from the base 1 when changing the cutting fluid, and the residual cutting fluid in the collection opening 3 can be cleaned to reduce the residue of old cutting fluid.

[0043] The conveyor wheels 14 are designed to facilitate the movement of the base 1, allowing it to be pushed to a specific position for cleaning or maintenance.
