Description

motor waterproof cover

The invention relates to a waterproof cover, in particular to a motor waterproof cover used for a motor shaft.

A motor in the prior art, especially a motor used to drive a wafer rotation carrier, its main structure includes a body and a drive shaft, the body is located at the bottom, one end of the drive shaft is connected to the body, and the other end is upward from the top of the body Extending out, the whole is upright. The turntable of the wafer rotating carrier is fixed on the drive shaft. When cleaning the wafer placed on the turntable, the drive shaft will start to rotate, so that the wafer will rotate synchronously. And spray the cleaning solution on the wafer, so as to achieve the effect that the cleaning solution can be evenly sprayed on the wafer and then dried.

However, in the aforementioned cleaning process, because the cleaning liquid is thrown out due to the centrifugal force of the wafer rotation, the thrown cleaning liquid will splash back when it hits the wall surface, and because the cleaning liquid is an acidic liquid, when When the splashed cleaning fluid is sprayed on the drive shaft, it is easy to flow into the motor body along the drive shaft, which will easily cause damage to the motor body and reduce the service life of the motor body after a long time; therefore, it is necessary to improve the above-mentioned problems and shortcomings. .

In view of the deficiencies in the prior art, the present invention provides a motor waterproof cover, which is fixed to the drive shaft of the motor by a joint, so as to achieve the same rotation with the drive shaft, and the joint and the shielding part can simultaneously achieve the purpose of shielding the drive shaft.

In order to achieve the above-mentioned purpose of the invention, the technical means adopted in the present invention is to design a motor waterproof cover, which includes: A cover body, which is a hollow tube and has a joint portion and a shielding portion, the joint portion is located at one end of the cover body, the shielding portion is located at the other end of the cover body, the joint portion forms an upper opening, a ring groove and a plurality of lock holes, the upper opening is located at the other end of the joint part relative to the shielding part, the annular groove is recessed around the inner wall of the joint part, and each of the lock holes is spaced around the joint part, the The shielding part is formed with a lower opening, the lower opening is located at the other end of the shielding part relative to the joint part, and the lower opening communicates with the upper opening; A waterproof piece is arranged in the ring groove.

Furthermore, in the motor waterproof cover, the joint portion is further formed with an upper ring slope, the upper ring slope is located on the outer wall surface of the joint portion, and the outer diameter of the upper ring slope gradually increases toward the shielding portion.

Furthermore, the motor waterproof cover, wherein the shielding part is further formed with a lower ring slope, the lower ring slope is located on the outer wall of the shielding part, and the outer diameter of the lower ring slope gradually increases toward the lower opening .

Further, in the motor waterproof cover, the waterproof member is an annular rubber ring.

The advantage of the present invention is that, by setting the present invention on the drive shaft of a drive motor, when the wafer cleaning operation is performed, the drive shaft and the present invention are in a state of synchronous rotation, and the cleaning liquid sprayed on the wafer After being thrown out and hitting the wall, the cleaning liquid that splashes back will be blocked by the slope of the upper ring and the slope of the lower ring of the present invention, and will be thrown away by centrifugal force again to prevent the cleaning liquid from flowing into the body of the drive motor along the drive shaft. This prevents the cleaning fluid from damaging the drive motor body and improves the service life of the drive motor.

The technical means adopted by the present invention to achieve the predetermined invention objectives are further described below in conjunction with the drawings and preferred embodiments of the present invention.

Please refer to FIG. 1 and FIG. 3 , the motor waterproof cover of the present invention includes a cover body 10 and a waterproof member 20 .

Please refer to Fig. 2 to Fig. 4, the cover body 10 is a hollow tube body, which has a joint part 11 and a shielding part 12, the joint part 11 is located at one end of the cover body 10, and the shielding part 12 is located at the other end of the cover body 10. At one end, the joint part 11 and the shielding part 12 are integrally formed. The joint part 11 is formed with an upper opening 111, a ring groove 112, a plurality of lock holes 113 and an upper ring slope 114. The upper opening 111 is located at the other side of the joint part 11 relative to the shielding part 12. At one end, the ring groove 112 is recessed around the inner wall surface of the joint part 11, each lock hole 113 is circumferentially and spaced through the joint part 11 and each lock hole 113 is formed with an internal thread, and the upper ring slope 114 is formed on the outer wall surface of the joint part 11, The outer diameter of the upper ring slope 114 gradually increases from an end adjacent to the upper opening 111 toward the shielding portion 12 .

2 to 5, the shielding portion 12 is formed with a lower opening 121 and a lower ring slope 122, the lower opening 121 is located at the other end of the shielding portion 12 relative to the joint portion 11, the lower opening 121 communicates with the upper opening 111, The lower ring slope 122 is formed on the outer wall of the shielding portion 12 , and the outer diameter of the lower ring slope 122 gradually increases from an end adjacent to the joint portion 11 toward the lower opening 121 .

The waterproof member 20 is an annular rubber ring, which is arranged in the ring groove 112 of the joint portion 11, but not limited thereto, and the form of the waterproof member 20 can be changed according to the needs of users.

When the present invention is in use, please refer to Fig. 6 and Fig. 7, for ease of description, only take a drive motor 90 and a support table 91 as an example to cooperate, and the support table 91 is used to support and fix a wafer rotating device (in the figure). Not shown), the drive motor 90 includes a body 92 and a drive shaft 93, one end of the drive shaft 93 is rotatably connected to the body 92, and the other end of the drive shaft 93 is connected to the turntable of the wafer rotation device (not shown in the drawings) , a wafer (not shown in the drawings) is placed on the turntable, the support table 91 runs through a perforation 94, one end of the support table 91 is fixed to the body 92, the drive shaft 93 passes through the perforation 94, and the drive shaft 93 can be opposite to the support table 91 turn.

The present invention is sleeved on the drive shaft 93, and a plurality of locking pieces (not shown in the drawings) are passed through each lock hole 113 to lock the joint part on the drive shaft 93, and the shielding part 12 and the support table 91 are maintained There is a gap, so when the wafer cleaning operation is carried out, the drive shaft 93 and the present invention are in a state of synchronous rotation. When the cleaning liquid sprayed on the wafer is thrown out and hits the wall surface, the cleaning liquid that is splashed back will be absorbed by the present invention. It is blocked and thrown away again by centrifugal force to prevent the cleaning liquid from flowing into the body 92 along the drive shaft 93. Specifically, when the cleaning liquid splashes back toward the perforation 94 of the support table 91, it can be directly blocked by the present invention When the cleaning liquid is splashed back towards the direction of the drive shaft 93 located above the present invention, the cleaning liquid remaining on the drive shaft 93 can be stopped by the waterproof member 20 even if it flows downward along the drive shaft 93, The stopped cleaning liquid can be discharged outward along the upper ring slope 114 and the lower ring slope 122, thereby preventing the cleaning liquid from flowing into the body 92 along the drive shaft 93 and causing damage, and improving the service life of the drive motor 90. .
