Description

Technical Field

[0001] The invention relates to the technical field of stator varnishing for motor production, and in particular to a stator varnishing device and method for motor production. Background Art

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It uses an energized coil, that is, a stator winding, to generate a rotating magnetic field and act on the rotor to form a magneto-electrodynamic rotating torque. The electric motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field is related to the direction of the current and the direction of the magnetic flux lines. The working principle of the electric motor is that the magnetic field acts on the force of the current to make the motor rotate. In order to increase the service life of the motor, during the production of the motor, a layer of paint is usually added to the stator by immersion using a paint immersion device, which can effectively increase the anti-corrosion and anti-rust effect of the motor stator. After the motor stator is dipped in paint, the excess paint on the motor stator needs to be shaken off by centrifugal force, and then the moisture in the paint after the motor stator is dipped in paint is dried by heating. At this time, the motor stator dips in paint and the subsequent motor assembly and production can be carried out.

[0003] When the existing paint dipping equipment is used to paint the motor stator, due to the complex internal structure of some motor stators, the paint cannot be more fully in contact with the complex surface of the motor stator. In order to increase the effect of the paint dipping, a vacuum method is usually used to increase the effect of the paint dipping. In this process, the gas inside the paint dipping equipment needs to be pumped out to form a vacuum, and then the paint for the paint dipping can be put into the paint dipping equipment to paint the motor stator. This makes the motor stator paint dipping process more complicated, and there is more preliminary preparation work, resulting in a longer time-consuming motor stator paint dipping process, which will affect the paint dipping efficiency of the motor stator to a certain extent, and then will also affect the subsequent motor assembly production efficiency. To this end, we propose a stator paint dipping device and method for motor production.

[0004] Combining the above problems, we will find that it is difficult to avoid the above problems at the same time when using the existing stator varnishing equipment for motor production on the market, and even if it can be solved, it needs to be solved with the cooperation of external tools, which cannot achieve the desired effect. Therefore, we propose a stator varnishing equipment and method for motor production. Summary of the invention

[0015] The method of using the stator varnishing equipment for motor production is as follows; S1. The staff starts the servo motor, the first electric push rod and the second electric push rod through the external control switch and power supply. The tension provided by the contraction of the first electric push rod can cooperate with the clamping relationship between the moving block and the first clamping block, and the extension and contraction of the telescopic frame to drive the protective cover, the connecting frame and the second motor stator to move downward through the unloading chute in the middle position of the limit plate until the protective cover contacts the upper surface of the varnish dipping box. At this time, the varnish dipping process of the motor stator can be carried out; S2. The staff starts the rotating motor through the external control switch and power supply. The power provided by the rotating motor and the protective cover can drive the connecting shaft to rotate, and then the connecting rod can be driven to rotate through the reversing of the gear commutator and the assistance of the auxiliary bearing. At this time, the rotating rod can drive the eccentric block to rotate. When the eccentric block rotates, centrifugal force will be generated due to the unbalanced gravity distribution. At this time, a certain vibration force can be generated. Through the limit of the bearing frame, the vibration force can be transmitted to the connecting frame while stabilizing the rotation of the rotating rod, so that the connecting frame drives the second motor stator to vibrate inside the immersion box. When the connecting frame vibrates, the vibration spring and the fixing ring can not only further amplify the vibration amplitude, but also reduce the vibration force to the protective cover to a certain extent, reduce the impact of vibration on other equipment, and the fixing spring can also further reduce the transmission of vibration force, so that the rotating rod can vibrate smoothly without transmitting too much vibration force to the connecting rod; S3. When the paint dipping is completed, the first electric push rod cooperates with the first clamping block and the moving block to drive the protective cover to move upward until it passes through the feeding chute at the middle position and enters the sliding chute. The first electric push rod stops running. At this time, the power provided by the servo motor cooperates with the bracket to drive the bidirectional screw to rotate, thereby driving the moving plate, the telescopic frame and the protective cover to move to the right, and the moving block will slide to the right inside the sliding chute until the moving block is clamped with the second clamping block on the right side. The servo motor stops rotating, and at this time the moving plate also moves to the rightmost end connected to the bidirectional screw thread. Since the second clamping block on the right side is clamped with the moving block, the second electric push rod on the right side can cooperate with the second clamping block and the feeding chute on the right side to drive the protective cover, the connecting frame and the second motor stator to move downward; S4. As the second electric push rod on the right cooperates with the right feeding trough and the second clamping block, the downward pressure generated when the protective cover, the connecting frame and the second motor stator move downward can drive the second motor stator to enter the inside of the feeding seat. At this time, the positioning frame will enter the inside of the guide frame, and the guide frame will be inserted into the gap between the positioning frame and the moving frame, and the sliding column will also enter the inside of the guide groove. As the connecting frame continues to move downward, the sliding column will drive the positioning block to retract into the inside of the positioning frame under the guidance of the guide groove, thereby releasing the limit of the moving frame. At this time, the tension of the limit spring will pull the moving frame downward to the bottom of the positioning block, and then the moving frame will cooperate with the guide rod to pull the clamping frame back to the inside of the connecting frame, loosening the limit on the second motor stator, so that it can fall into the inside of the feeding seat to complete the feeding work; S5. After the second motor stator unloads, the second electric push rod pushes the moving block upward again to enter the sliding slot, and the servo motor rotates again. The bidirectional special thread on the bidirectional screw can drive the moving plate to move left to the loading position. At this time, the moving plate is located at the leftmost end of the bidirectional screw thread connection, and the moving block is connected with the second clamping block on the left side. The protective cover and the connecting frame can be driven to move downward by the left second electric push rod in conjunction with the left unloading slot; When the second electric push rod on the left cooperates with the moving block and the second clamping block to drive the protective cover and the connecting frame to move downward, the downward pressure generated can allow the connecting frame to pass through the first motor stator and enter the interior of the loading seat. At this time, the bottom surface of the moving seat will contact the upper surface of the upper frame. When the connecting frame continues to move downward to the upper frame, it will limit the position of the moving seat, allowing the moving seat to slide on the positioning frame, and the limit spring will be stretched. At the same time, the inclined surface of the positioning block will first contact the upper surface of the moving frame, and be forced to retract into the positioning frame under pressure to shrink the reset spring, and the moving cooperation guide rod of the moving seat will push the clamping frame outward to the connecting frame until the outer surface of the clamping frame contacts the inner wall of the first motor stator. At this time, the moving seat will move upward to the top of the positioning block, and then the thrust provided by the reset spring will push the positioning block to slide out from the inside of the positioning frame. At this time, the upper surface of the positioning block contacts the bottom surface of the moving frame to limit the position of the moving seat, so that the clamping frame is always in contact with the inner wall of the first motor stator, completing the clamping and material taking work of the first motor stator; S7. After the material is taken, the second electric push rod on the left cooperates with the moving block and the second clamping block on the left to drive the protective cover to move upward until the moving block re-enters the sliding groove. The servo motor's own characteristics can be used to control its number of rotations, and then the servo motor cooperates with the bidirectional screw to accurately control the position of the moving plate, so that the moving plate drives the protective cover to move to the top of the immersion box for the next motor stator immersion process.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a vibrating force for the second motor stator that enters the paint dipping box for paint dipping by setting a paint dipping vibration unit, so that the second motor stator can vibrate quickly when being painted in the paint dipping box, and then the bubbles inside the second motor stator can be discharged outward by using the vibration force, so that the paint for paint dipping can be more quickly attached to the complex surface of the second motor stator, without the need to use a vacuum pumping device, thereby effectively reducing the preliminary preparation work of the motor stator paint dipping process, reducing the motor stator paint dipping cost, and shortening the time required for the motor stator paint dipping process to a certain extent, increasing the motor stator paint dipping efficiency, and ensuring the rapid progress of subsequent motor assembly work; 2. The present invention, by providing a paint-dipping auxiliary unit, can more conveniently and quickly move the motor stator that needs to be painted from the discharge position to the inside of the paint-dipping box for paint-dipping processing. After the paint-dipping processing is completed, the motor stator can be taken out from the inside of the paint-dipping box and moved to the unloading position, so that only one set of moving mechanisms is needed for the paint-dipping of the motor stator, which increases the convenience of movement of the motor stator during paint-dipping and further improves the processing efficiency of the motor stator by the stator paint-dipping equipment for motor production; 3. The present invention can complete the automatic clamping and unloading of the motor stator by setting a clamping mechanism in conjunction with a paint dipping auxiliary unit, making the loading and unloading of the motor stator during paint dipping more convenient and quick, without the need to use additional equipment to fix the motor stator, making the motor production stator paint dipping equipment more efficient and convenient.

The two brackets 13 are internally connected to a bidirectional screw 2203 for common rotation. The bidirectional screw 2203 is threadedly connected to the moving plate 2201. A servo motor 2204 is arranged on the left side of one of the brackets 13. The servo motor 2204 can control the speed and position accuracy very accurately, and can convert the voltage signal into torque.

After the dip painting process is completed, the motor stator can also be taken out from the inside of the paint dipping box 12 and moved to the feeding position, so that only one set of moving mechanism is needed when the motor stator is dipped in paint, which increases the convenience of movement when the motor stator is dipped in paint, and further improves the processing efficiency of the motor stator by the stator dip painting equipment for motor production; The movable plate 2201 is internally slidably connected with a stabilizing rod 2213, and the two ends of the two stabilizing rods 2213 are respectively fixedly connected to the side surfaces of the two brackets 13 that are close to each other.

The bottom surface of each reinforcement ring 2215 is fixedly connected to the upper surface of the base plate 11. The reinforcement rings 2215 can increase the connection firmness between the first electric push rods 2208 and the second electric push rods 2211 and the base plate 11, making the connection between the first electric push rods 2208 and the second electric push rods 2211 and the base plate 11 tighter and more reliable, thereby improving the use stability of the first electric push rods 2208 and the second electric push rods 2211.

[0025] The specific implementation method of this embodiment is as follows: the staff starts the servo motor 2204, the first electric push rod 2208 and the second electric push rod 2211 through the external control switch and power supply, and utilizes the pulling force provided by the contraction of the first electric push rod 2208 to cooperate with the clamping relationship between the moving block 2209 and the first clamping block 2210, as well as the extension and contraction of the telescopic frame 2202, to drive the protective cover 2101, the connecting frame 2102 and the second motor stator 2103 to move downward through the unloading chute 2207 in the middle position on the limit plate 2205 until the protective cover 2101 contacts the upper surface of the varnish dipping box 12, at which time the varnish dipping process of the motor stator can be carried out, and when the varnish dipping is completed, the first electric push rod 2208 cooperates with the first clamping block 2210 and the moving block 22 09 drives the protective cover 2101 to move upward until it passes through the unloading chute 2207 in the middle position and enters the sliding groove 2206. The first electric push rod 2208 stops running. At this time, the power provided by the servo motor 2204 cooperates with the bracket 13 to drive the bidirectional screw 2203 to rotate, thereby driving the movable plate 2201, the telescopic frame 2202 and the protective cover 2101 to move to the right, and the movable block 2209 will slide to the right inside the sliding groove 2206 until the movable block 2209 is engaged with the second clamping block 2212 on the right side. The servo motor 2204 stops rotating, and at this time the movable plate 2201 also moves to the rightmost end threadedly connected to the bidirectional screw 2203. Since the second clamping block 2212 on the right side is engaged with the movable block 2209, the movable plate 2201 is moved to the right. The second electric push rod 2211 on the right side can cooperate with the second clamping block 2212 and the right feeding trough 2207 to drive the protective cover 2101, the connecting frame 2102 and the second motor stator 2103 to move downward to complete the feeding work. After the second motor stator 2103 has fed, the second electric push rod 2211 pushes the moving block 2209 to move upward into the sliding groove 2206 again, and the servo motor 2204 rotates again, and the bidirectional special thread on the bidirectional screw 2203 can drive the moving plate 2201 to move left to the feeding position. At this time, the moving plate 2201 is located at the leftmost end of the threaded connection of the bidirectional screw 2203, and the moving block 2209 is clamped with the second clamping block 2212 on the left side. The material trough 2207 can drive the protective cover 2101 and the connecting frame 2102 to move downward to complete the material picking work, and then the second electric push rod 2211 on the left side pushes the moving block 2209 upward through the left material discharge trough 2207 and back into the sliding groove 2206. After the material picking is completed, the servo motor 2204 can control its number of rotations by using its own characteristics, so that the servo motor 2204 cooperates with the bidirectional screw 2203 to accurately control the position of the moving plate 2201, so that the moving plate 2201 drives the protective cover 2101 to move to the top of the varnish dipping box 12 for the next motor stator varnishing process, so that the stator varnishing equipment for motor production can more conveniently and quickly move the motor stator that needs to be varnished from the discharge position to the inside of the varnish dipping box 12 for varnishing.After the varnishing process is completed, the motor stator can be taken out from the varnishing box 12 and moved to the unloading position, so that only one set of moving mechanisms is needed for varnishing the motor stator, which increases the convenience of movement during varnishing of the motor stator and further improves the processing efficiency of the motor stator by the stator varnishing equipment for motor production.

The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0027] As a further limitation of the clamping mechanism 3 of the present invention, a clamping mechanism 3 is provided on the left side of the paint dipping vibration unit 21, and the clamping mechanism 3 is used in conjunction with the paint dipping auxiliary mechanism 2, and the clamping mechanism 3 can clamp or release the first motor stator 14; The clamping mechanism 3 includes three material loading seats 301 and three material unloading seats 303. The bottom surface of each material loading seat 301 and the bottom surface of each material unloading seat 303 are fixedly connected to the upper surface of the bottom plate 11. Each first motor stator 14 is located inside the material loading seat 301. The upper surface of each material loading seat 301 is fixedly connected to an upper top frame 302. The upper surface of each material unloading seat 303 is fixedly connected to a guide frame 304. Two guide grooves 313 are provided on the opposite sides of each guide frame 304. Each connecting frame 2102 The interior of each connecting frame 2102 is slidably connected with four clamping frames 305, the outer surface of each clamping frame 305 is in contact with the inner wall of the second motor stator 2103, each connecting frame 2102 is provided with a moving frame 306, the outer surface of each moving frame 306 is movably hinged with four guide rods 307, the other end of each guide rod 307 is movably hinged with the clamping frame 305, the inner wall of each connecting frame 2102 is fixedly connected with a positioning frame 308, the inner wall of each moving frame 306 is in contact with the outer surface of the positioning frame 308 The interior of each positioning frame 308 is slidably connected to two positioning blocks 309, the bottom surface of each positioning block 309 is an inclined surface, the upper surface of each positioning block 309 is in contact with the bottom surface of the moving frame 306, and the side of each group of positioning blocks 309 close to each other is fixedly connected to two return springs 310, and the number of each group of positioning blocks 309 is two, and the other end of each return spring 310 is fixedly connected to the inner wall of the positioning frame 308, and the front and back sides of each positioning block 309 are fixedly connected to The sliding column 311 and the bottom surface of each movable frame 306 are fixedly connected with four limit springs 312, and the bottom end of each limit spring 312 is fixedly connected to the inner bottom wall of the connecting frame 2102. By setting the clamping mechanism 3 and cooperating with the paint dipping auxiliary unit 22, the automatic clamping and unloading of the motor stator can be completed, making the loading and unloading of the motor stator more convenient and quick during paint dipping, without the need to use additional equipment to fix the motor stator, making the motor production stator paint dipping equipment more efficient and convenient for the motor stator.

[0028] The specific implementation of this embodiment is as follows: when it is necessary to fix the first motor stator 14 on the connecting frame 2102, as the second electric push rod 2211 on the left cooperates with the moving block 2209 and the second clamping block 2212 to drive the protective cover 2101 and the connecting frame 2102 to move downward, the downward pressure generated can allow the connecting frame 2102 to pass through the first motor stator 14 and enter the interior of the loading seat 301. At this time, the bottom surface of the moving frame 306 will contact the upper surface of the upper frame 302. When the connecting frame 2102 continues to move downward to the upper frame 302, the position of the moving frame 306 will be limited, allowing the moving frame 306 to slide on the positioning frame 308, and the limit spring 312 will be stretched, and at the same time, the inclined surface of the positioning block 309 will The movable frame 306 first contacts with the upper surface thereof, and is forced to retract into the interior of the positioning frame 308 under pressure to shrink the return spring 310, and the movable frame 306 moves in coordination with the guide rod 307 to push the clamping frame 305 outwards from the connecting frame 2102 until the outer surface of the clamping frame 305 contacts the inner wall of the first motor stator 14. At this time, the movable frame 306 moves upwards to the top of the positioning block 309, and the thrust provided by the return spring 310 pushes the positioning block 309 to slide out of the positioning frame 308. At this time, the upper surface of the positioning block 309 contacts the bottom surface of the movable frame 306 to limit the position of the movable frame 306, so that the clamping frame 305 is always in contact with the inner wall of the first motor stator 14, thereby completing the clamping of the first motor stator 14. Clamping and picking up the material, when the painting work is completed, the second electric push rod 2211 on the right cooperates with the right feeding trough 2207 and the second clamping block 2212 to drive the protective cover 2101, the connecting frame 2102 and the second motor stator 2103 to move downward. The downward pressure generated can drive the second motor stator 2103 to enter the inside of the feeding seat 303. At this time, the positioning frame 308 will enter the inside of the guide frame 304. At the same time, the guide frame 304 will be inserted into the gap between the positioning frame 308 and the moving frame 306, and the sliding column 311 will also enter the inside of the guide groove 313. As the connecting frame 2102 continues to move downward, the sliding column 311 will drive the positioning block 309 to re-engage under the guidance of the guide groove 313. The movable frame 306 is retracted into the interior of the positioning frame 308, thereby releasing the limit on the movable frame 306. At this time, the tension of the limit spring 312 will pull the movable frame 306 downward to the bottom of the positioning block 309, and then the movable frame 306 cooperates with the guide rod 307 to pull the clamping frame 305 back to the interior of the connecting frame 2102, loosening the limit on the second motor stator 2103, so that it can fall into the unloading seat 303 to complete the unloading work, so that the stator dipping equipment for motor production can complete the automatic clamping and unloading of the motor stator, making the loading and unloading of the motor stator more convenient and quick during the paint dipping, without the need to use additional equipment to fix the motor stator, making the stator dipping equipment for motor production more efficient and convenient when painting the motor stator.

[0029] The method of using the stator varnishing equipment for motor production is as follows; S1. The staff starts the servo motor 2204, the first electric push rod 2208 and the second electric push rod 2211 through the external control switch and power supply. The tension provided by the contraction of the first electric push rod 2208 can cooperate with the clamping relationship between the moving block 2209 and the first clamping block 2210, and the extension and contraction of the telescopic frame 2202 to drive the protective cover 2101, the connecting frame 2102 and the second motor stator 2103 to move downward through the unloading trough 2207 in the middle position of the limit plate 2205 until the protective cover 2101 contacts the upper surface of the varnish dipping box 12. At this time, the varnish dipping process of the motor stator can be carried out; S2. The staff starts the rotating motor 2112 through the external control switch and power supply. The power provided by the rotating motor 2112 and the protective cover 2101 can drive the connecting shaft 2114 to rotate, and then the reversing of the gear commutator 2113 and the assistance of the auxiliary bearing 2115 can drive the connecting rod 2106 to rotate. At this time, the rotating rod 2109 can drive the eccentric block 2110 to rotate. When the eccentric block 2110 rotates, centrifugal force will be generated due to the unbalanced gravity distribution. At this time, a certain vibration force can be generated. Through the limit of the bearing frame 2111, the rotating rod 2109 can be stabilized. When the connecting frame 2102 rotates, the vibration force can be transmitted to the connecting frame 2102, so that the connecting frame 2102 drives the second motor stator 2103 to vibrate inside the varnish dipping box 12. When the connecting frame 2102 vibrates, the vibration spring 2105 cooperates with the fixing ring 2104 to not only further amplify the vibration amplitude, but also reduce the vibration force to be transmitted to the protective cover 2101 to a certain extent, thereby reducing the impact of the vibration on other equipment. Moreover, the fixing spring 2108 can also further reduce the transmission of the vibration force, so that the rotating rod 2109 can vibrate smoothly without transmitting too much vibration force to the connecting rod 2106. S3. When the paint dipping is completed, the first electric push rod 2208 cooperates with the first clamping block 2210 and the moving block 2209 to drive the protective cover 2101 to move upward until it passes through the unloading chute 2207 in the middle position and enters the sliding groove 2206. The first electric push rod 2208 stops running. At this time, the power provided by the servo motor 2204 cooperates with the bracket 13 to drive the bidirectional screw 2203 to rotate, thereby driving the moving plate 2201, the telescopic frame 2202 and the protective cover 2101 to move to the right, and the moving block 2209 will move in the sliding groove 2206. The inside of the slot 2206 slides to the right until the moving block 2209 is engaged with the second clamping block 2212 on the right side, and the servo motor 2204 stops rotating. At this time, the moving plate 2201 also moves to the rightmost end threadedly connected with the bidirectional screw 2203. Since the second clamping block 2212 on the right side is engaged with the moving block 2209, the second electric push rod 2211 on the right side can cooperate with the second clamping block 2212 and the right side feeding chute 2207 to drive the protective cover 2101, the connecting frame 2102 and the second motor stator 2103 to move downward. S4, as the second electric push rod 2211 on the right cooperates with the right feeding trough 2207 and the second clamping block 2212, the downward pressure generated when the protective cover 2101, the connecting frame 2102 and the second motor stator 2103 move downward can drive the second motor stator 2103 to enter the inside of the feeding seat 303, at this time, the positioning frame 308 will enter the inside of the guide frame 304, and the guide frame 304 will be inserted into the gap between the positioning frame 308 and the moving frame 306, and the sliding column 311 will also enter the inside of the guide groove 313, and then As the connecting frame 2102 continues to move downward, the sliding column 311 will, under the guidance of the guide groove 313, drive the positioning block 309 to retract into the positioning frame 308, thereby releasing the limit on the moving frame 306. At this time, the tension of the limit spring 312 will pull the moving frame 306 downward to the bottom of the positioning block 309, and then the moving frame 306 cooperates with the guide rod 307 to pull the clamping frame 305 back into the connecting frame 2102, releasing the limit on the second motor stator 2103, so that it can fall into the unloading seat 303 to complete the unloading work; S5. After the second motor stator 2103 unloads, the second electric push rod 2211 pushes the moving block 2209 upwards to enter the sliding slot 2206 again, and the servo motor 2204 rotates again. The bidirectional special thread on the bidirectional screw 2203 can drive the moving plate 2201 to move leftward to the loading position. At this time, the moving plate 2201 is located at the leftmost end of the threaded connection of the bidirectional screw 2203, and the moving block 2209 is engaged with the left second clamping block 2212. The left second electric push rod 2211 cooperates with the left unloading slot 2207 to drive the protective cover 2101 and the connecting frame 2102 to move downward. S6. As the second electric push rod 2211 on the left cooperates with the moving block 2209 and the second clamping block 2212 to drive the protective cover 2101 and the connecting frame 2102 to move downward, the downward pressure generated can allow the connecting frame 2102 to pass through the first motor stator 14 and enter the interior of the loading seat 301. At this time, the bottom surface of the moving frame 306 will contact the upper surface of the upper frame 302. When the connecting frame 2102 continues to move downward until the upper frame 302 limits the position of the moving frame 306, the moving frame 306 slides on the positioning frame 308, and the limit spring 312 is stretched. At the same time, the inclined surface of the positioning block 309 will first contact the upper surface of the moving frame 306 and shrink under pressure. The movable frame 306 moves into the interior of the positioning frame 308 to shrink the return spring 310, and the movement of the movable frame 306 cooperates with the guide rod 307 to push the clamping frame 305 outward from the connecting frame 2102 until the outer surface of the clamping frame 305 contacts the inner wall of the first motor stator 14. At this time, the movable frame 306 moves upward to the top of the positioning block 309, and then the thrust provided by the return spring 310 pushes the positioning block 309 to slide out from the interior of the positioning frame 308. At this time, the upper surface of the positioning block 309 contacts the bottom surface of the movable frame 306 to limit the position of the movable frame 306, so that the clamping frame 305 is always in contact with the inner wall of the first motor stator 14, completing the clamping and material taking work of the first motor stator 14; S7. After the material is taken, the second electric push rod 2211 on the left cooperates with the moving block 2209 and the second clamping block 2212 on the left to drive the protective cover 2101 to move upward until the moving block 2209 re-enters the sliding groove 2206, and the servo motor 2204 can control its number of rotations by utilizing its own characteristics, so that the servo motor 2204 cooperates with the bidirectional screw 2203 to accurately control the position of the moving plate 2201, and the moving plate 2201 drives the protective cover 2101 to move to the top of the varnish dipping box 12 for the next motor stator varnish dipping process.

Then, through the reversing of the gear commutator (2113) and the assistance of the auxiliary bearing (2115), the connecting rod (2106) can be driven to rotate. At this time, the rotating rod (2109) can drive the eccentric block (2110) to rotate. When the eccentric block (2110) rotates, centrifugal force is generated due to the unbalanced gravity distribution. At this time, a certain vibration force can be generated. Through the limit of the bearing frame (2111), the rotating rod (2109) can be stabilized. 109) while rotating, the vibration force can be transmitted to the connecting frame (2102), so that the connecting frame (2102) drives the second motor stator (2103) to vibrate inside the varnish dipping box (12). When the connecting frame (2102) vibrates, the vibration spring (2105) cooperates with the fixing ring (2104) to not only further amplify the vibration amplitude, but also to a certain extent reduce the vibration force transmitted to the protective cover (2101), thereby reducing the impact of the vibration on other equipment. In addition, the fixing spring (2108) can also further reduce the transmission of the vibration force, so that the rotating rod (2109) can vibrate smoothly without transmitting too much vibration force to the connecting rod (2106); S3. When the paint dipping is completed, the first electric push rod (2208) cooperates with the first clamping block (2210) and the moving block (2209) to drive the protective cover (2101) to move upward until it passes through the unloading trough (2207) in the middle position and enters the interior of the sliding groove (2206). The first electric push rod (2208) stops running. At this time, the power provided by the servo motor (2204) cooperates with the bracket (13) to drive the bidirectional screw (2203) to rotate, thereby driving the moving plate (2201), the telescopic frame (2202) and the protective cover (2101) to move to the right, and the moving block (2209) will move on the sliding groove (2206). The inside of the slot (2206) slides to the right until the moving block (2209) is engaged with the second engaging block (2212) on the right side, and the servo motor (2204) stops rotating. At this time, the moving plate (2201) also moves to the rightmost end threadedly connected with the bidirectional screw (2203). Since the second engaging block (2212) on the right side is engaged with the moving block (2209), the second electric push rod (2211) on the right side can cooperate with the second engaging block (2212) and the right side feeding chute (2207) to drive the protective cover (2101), the connecting frame (2102) and the second motor stator (2103) to move downward. S4. As the second electric push rod (2211) on the right cooperates with the right material discharge trough (2207) and the second clamping block (2212), the downward pressure generated when the protective cover (2101), the connecting frame (2102) and the second motor stator (2103) move downward can drive the second motor stator (2103) to enter the inside of the material discharge seat (303). At this time, the positioning frame (308) will enter the inside of the guide frame (304). At the same time, the guide frame (304) will be inserted into the gap between the positioning frame (308) and the moving frame (306), and the sliding column (311) will also enter the inside of the guide groove (313). As the connecting frame (2102) continues to move downward, the sliding column (311) will, under the guidance of the guide groove (313), drive the positioning block (309) to retract into the positioning frame (308), thereby releasing the limit on the movable frame (306). At this time, the tension of the limit spring (312) will pull the movable frame (306) downward to the bottom of the positioning block (309), and then the movable frame (306) will cooperate with the guide rod (307) to pull the clamping frame (305) back into the connecting frame (2102), releasing the limit on the second motor stator (2103), so that it can fall into the unloading seat (303) to complete the unloading work; S5. After the second motor stator (2103) unloads, the second electric push rod (2211) pushes the moving block (2209) upwards again and enters the sliding groove (2206). The servo motor (2204) rotates again, and the bidirectional special thread on the bidirectional screw (2203) can drive the moving plate (2201) to move leftward to the loading position. At this time, the moving plate (2201) is located at the leftmost end of the threaded connection of the bidirectional screw (2203), and the moving block (2209) is engaged with the left second clamping block (2212). The left second electric push rod (2211) cooperates with the left unloading groove (2207) to drive the protective cover (2101) and the connecting frame (2102) to move downward. S6. As the second electric push rod (2211) on the left cooperates with the moving block (2209) and the second clamping block (2212) to drive the protective cover (2101) and the connecting frame (2102) to move downward, the downward pressure generated can allow the connecting frame (2102) to pass through the first motor stator (14) and enter the interior of the loading seat (301). At this time, the bottom surface of the moving frame (306) will contact the upper surface of the upper frame (302). When the connecting frame (2102) continues to move downward to the position where the upper frame (302) limits the position of the moving frame (306), the moving frame (306) slides on the positioning frame (308), and the limit spring (312) is stretched. At the same time, the inclined surface of the positioning block (309) will first contact the upper surface of the moving frame (306) and be retracted under pressure. The interior of the positioning frame (308) contracts the return spring (310), and the movement of the movable frame (306) cooperates with the guide rod (307) to push the clamping frame (305) outward from the connecting frame (2102) until the outer surface of the clamping frame (305) contacts the inner wall of the first motor stator (14). At this time, the movable frame (306) moves upward to the top of the positioning block (309), and then the thrust provided by the return spring (310) pushes the positioning block (309) to slide out from the interior of the positioning frame (308). At this time, the upper surface of the positioning block (309) contacts the bottom surface of the movable frame (306) to limit the position of the movable frame (306), so that the clamping frame (305) is always in contact with the inner wall of the first motor stator (14), thereby completing the clamping and material removal work of the first motor stator (14); S7. After the material is taken, the second electric push rod (2211) on the left cooperates with the moving block (2209) and the second clamping block (2212) on the left to drive the protective cover (2101) to move upward until the moving block (2209) re-enters the interior of the sliding groove (2206). The number of rotations of the servo motor (2204) can be controlled by utilizing its own characteristics, and then the servo motor (2204) cooperates with the bidirectional screw (2203) to accurately control the position of the moving plate (2201), so that the moving plate (2201) drives the protective cover (2101) to move to the top of the varnish dipping box (12) for the next motor stator varnish dipping process.
