Description

Technical Field

[0001] This utility model relates to the field of air-electric spindle technology, specifically to an air-electric spindle for a dicing cutter that uses pneumatic control of carbon brush conductive tool setting mode. Background Technology

[0002] Carbon brush conductive dicing machine air-electric spindle is typically used in precision machining or material cutting to improve the precision of cutting wafers, ceramics, quartz, and other materials in the semiconductor industry.

[0003] However, existing carbon brush conductive blade setting mode dicing cutter air-electric spindles suffer from poor conductivity, carbon brush friction heating, graphite dust contamination, and even carbon brush wear and spindle vibration, which can easily affect the lifespan of the existing carbon brush conductive blade setting mode dicing cutter air-electric spindle. In addition, the existing carbon brush conductive blade setting mode dicing cutter air-electric spindle cannot filter the incoming air, which can easily cause contamination or even damage to the spindle and other critical components.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In response to the problems in related technologies, this utility model proposes an air-electric spindle for a dicing cutter using pneumatic control of carbon brush conductive blade setting mode, in order to overcome the aforementioned technical problems existing in the prior art.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A pneumatically controlled carbon brush conductive cutting spindle for a dicing machine includes a shaft mounting cylinder. A cutting assembly is located at one end of the inner wall of the shaft mounting cylinder. The cutting assembly includes a shaft mounted on the inner wall of the shaft mounting cylinder. A limit thrust bearing is corresponding to the flange surface of the shaft. An end cap is mounted on one end of the limit thrust bearing, and one end of the end cap contacts one end of the shaft mounting cylinder. A conical fixed cutter disc seat is located at one end of the shaft. A grinding wheel is mounted on one side of the conical fixed cutter disc seat, and a cutter disc cover is located on one side of the grinding wheel. A pressure nut contacts one side of the cutter disc cover. The inner wall of the pressure nut is threadedly connected to one end of the conical fixed cutter disc seat. A threaded hole is opened at the other end of the shaft, and a copper nut is threadedly connected to the inner wall of the threaded hole. A control assembly is located at the other end of the shaft mounting cylinder. A conductive component is located on the inner wall of the control assembly, and a filter assembly is connected to one end of the control assembly.

[0008] Furthermore, in order to better control the pneumatic spindle of the dicing cutter in blade mode, the control component includes a carbon brush holder installed on the inner wall of one end of the shaft mounting cylinder. The carbon brush holder has multiple connection holes, and a connecting screw is installed on the bottom surface of the connection hole. One end of the connecting screw is threaded to the shaft mounting cylinder, and an air inlet connector is provided on one side of the carbon brush holder.

[0009] Furthermore, the conductive component includes a mounting groove on one side of the carbon brush holder, multiple conductive plates on the bottom surface of the mounting groove, mounting screws on the conductive plates, one end of the mounting screws being threaded to one side of the carbon brush holder, a sealing cap installed on the inner wall of the mounting groove, multiple mounting holes on one end of the carbon brush holder, the mounting holes being located between the conductive plates, a set screw being installed inside the mounting hole, a spring being in contact with one end of the set screw, and a carbon brush being in contact with the inner wall of one end of the spring, and one end of the carbon brush and the carbon brush holder being opposite to a copper nut.

[0010] Furthermore, to better protect the spindle and other critical components from contamination, the filter assembly includes a delivery pump connected to one end of the air inlet connector, with a filter box extending through one end of the delivery pump. The inner wall of the filter box is fitted with a filter screen and an activated carbon plate, and an air inlet is provided on one side of the filter box.

[0011] Furthermore, connector one, connector two, and connector three are respectively provided on one side of the carbon brush holder.

[0012] Furthermore, an air passage hole is provided on one side of the carbon brush holder, which is connected to the inner wall of the mounting hole and is close to the spring and set screw.

[0013] Furthermore, a stator coil is provided on the inner wall of the rotating shaft mounting cylinder, and a rotor is correspondingly provided on the inner wall of the stator coil, with the rotor mounted on one end of the rotating shaft.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) By using the conductive component in the control component, the carbon brush can be brought into contact with the conductor when the height needs to be measured. During the non-measurement period of the cutting operation, the carbon brush is pulled back by the spring to avoid contact, which reduces wear, improves the spindle life, reduces the impact of carbon brush on spindle vibration, and eliminates the impact of carbon brush friction heat and graphite dust pollution. At the same time, the filter component in the control component can effectively purify the compressed air entering the system, further protecting the spindle and other key components from pollution.

[0016] (2) The cutting components installed in the rotating shaft mounting cylinder facilitate better cutting of wafers, ceramics, and quartz in the semiconductor industry. At the same time, the control components installed in the rotating shaft mounting cylinder combine pneumatic control technology with carbon brush conductive technology to realize the cutting mode of the dicing machine air electric spindle, which improves the accuracy and stability of the cutting process and solves the problems of overheating and wear that may exist in traditional electric spindles.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1;

[0029] like Figures 1-7 As shown, according to an embodiment of the present invention, an air-electric spindle for a dicing cutter using a pneumatically controlled carbon brush conductive blade setting mode includes a shaft mounting cylinder 1. A stator coil 10 is provided on the inner wall of the shaft mounting cylinder 1. The stator coil 10 is composed of a coil and a stator coil core.

[0030] A cutting assembly 2 is provided at one end of the inner wall of the shaft mounting cylinder 1. The cutting assembly 2 includes a shaft 201 disposed on the inner wall of the shaft mounting cylinder 1. The flange surface of the shaft 201 corresponds to a limit thrust bearing 202. Multiple sealing gaskets are installed on both sides of the limit thrust bearing 202. The sealing gaskets contact the end cover 203 and the shaft mounting cylinder 1 respectively. An end cover 203 is installed at one end of the limit thrust bearing 202. One end of the end cover 203 contacts one end of the shaft mounting cylinder 1. In actual use, the end cover 203 is threadedly connected to one end of the shaft mounting cylinder 1 by a screw. (Not shown in the figure), one end of the rotating shaft 201 is provided with a conical fixed cutter head seat 204. The interior of the conical fixed cutter head seat 204 is threadedly connected to one end of the rotating shaft 201 by a screw. A grinding wheel 205 is installed on one side of the conical fixed cutter head seat 204. A cutter head cover 206 is provided on one side of the grinding wheel 205. A pressure nut 207 is in contact with one side of the cutter head cover 206. The inner wall of the pressure nut 207 is threadedly connected to one end of the conical fixed cutter head seat 204. A threaded hole is opened at the other end of the rotating shaft 201. A copper nut 208 is threadedly connected to the inner wall of the threaded hole.

[0031] The other end of the rotating shaft mounting cylinder 1 is provided with a control component 3. The control component 3 includes a carbon brush holder 301 provided on the inner wall of one end of the rotating shaft mounting cylinder 1. Multiple sealing gaskets are provided on the carbon brush holder 301. Sealing gaskets 2 and 1 are used to prevent external dust, moisture and other impurities from entering the spindle, extending the service life of the equipment and ensuring internal cleanliness. Sealing gasket 3 contacts the inner wall of one side of the rotating shaft mounting cylinder 1. Multiple connection holes are provided on the carbon brush holder 301. Connecting screws 302 are installed on the bottom surface of the connection holes. One end of the connecting screws 302 is threaded to the rotating shaft mounting cylinder 1. An air inlet connector 303 is provided on one side of the carbon brush holder 301. Connector 1 6, connector 2 7 and connector 3 8 are respectively provided on one side of the carbon brush holder 301.

[0032] Example 2;

[0033] like Figures 1-7As shown, according to an embodiment of the present invention, a pneumatically controlled carbon brush conductive cutting machine spindle in a dicing mode includes a conductive component 4 disposed on the inner wall of the control component 3. The conductive component 4 includes a mounting groove on one side of the carbon brush holder 301. Multiple conductive plates 401 are disposed on the bottom surface of the mounting groove, with two plates in total. Each conductive plate 401 has a mounting screw 402, one end of which is threaded to one side of the carbon brush holder 301. A sealing cover 403 is installed on the inner wall of the mounting groove, and a sealing ring is disposed on the sealing cover 403 for sealing. The ring contacts the inner wall of the mounting groove. One end of the carbon brush holder 301 has multiple mounting holes, two in total. The mounting holes are located between the conductive plates 401. The mounting holes are equipped with set screws 404. One side of the carbon brush holder 301 has an air passage hole 9. The air passage hole 9 communicates with the inner wall of the mounting hole. The air passage hole 9 is close to the spring 405 and the set screw 404. One end of the set screw 404 contacts the spring 405. One end of the spring 405 contacts the carbon brush 406. One end of the carbon brush 406 and the carbon brush holder 301 are opposite to the copper nut 208.

[0034] The gap in the mounting hole acts as a cylinder, and the carbon brush 406 acts as a piston. When the tool is set to measure the height, the air pressure pushes the two carbon brushes 406 forward and presses them against the end face of the rotating shaft 201 and the copper nut 208 to create a conductive circuit. After the measurement is completed, the air is cut off, and the spring 405 pulls the carbon brushes 406 back and detaches them.

[0035] One end of the control component 3 is connected to the filter component 5. The filter component 5 includes a delivery pump 501 connected to one end of the air inlet connector 303. One end of the delivery pump 501 passes through the filter box 502. The inner wall of the filter box 502 is equipped with a filter screen plate 503 and an activated carbon plate 504. An air inlet port 505 is provided on one side of the filter box 502.

[0036] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0037] In summary, with the help of the above-mentioned technical solution of this utility model, when it is necessary to perform tool setting measurement, the external air source cooperates with the delivery pump 501 through the air inlet 505. After the external air source is filtered by the filter screen plate 503 and activated carbon plate 504 in the filter box 502, the clean air is delivered to the air inlet connector 303 through the delivery pump 501. The clean air enters the carbon brush holder 301, and then the delivered air pressure pushes the carbon brush 406 forward, so that the carbon brush 406 presses on the rotating shaft 201 and the copper nut 208, so that one end is connected to the conductive plate 401, the set screw 404, the carbon brush 406 and the copper nut 208, the rotating shaft 201, the cutting assembly 2, and through the connection The workpiece is connected to the contact point to form a conductive circuit, completing the tool setting measurement and ensuring the accuracy of the measurement data. After the measurement is completed, the air source is disconnected, and the spring 405 pulls the carbon brush 406 back to its original position, breaking the conductive circuit. At the same time, the carbon brush 406 connected to the conductive plate 401 separates from the copper nut 208 on the rotating shaft 201, avoiding unnecessary wear and contamination. Then, under pneumatic control, the carbon brush 406 connected to the conductive plate 401 only contacts the rotating shaft 201 and copper nut 208 when measurement is required, and remains separated at other times. This not only greatly reduces the wear of the carbon brush 406 and extends the service life of the spindle, but also reduces the vibration impact of the carbon brush 406 on the spindle, improving cutting accuracy and stability.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
