Description

Technical Field

[0001] This invention relates to the field of hollow cup motor technology, and more specifically, to a hollow cup motor potting device. Background Technology

[0002] A coreless motor is a type of motor that employs a coreless rotor structure. It boasts significant advantages such as high efficiency, high power density, and low moment of inertia, demonstrating irreplaceable application value in fields such as precision control, aerospace, and medical equipment. The coreless motor rotor is a hollow cup-shaped rotor composed of self-supporting cup-shaped coils. The wires of these coils extend to the motor's main shaft. To strengthen the connection between the cup-shaped coils and the main shaft, the joint between them needs to be potted; that is, the mating circular surface between the bottom of the cup-shaped coil and the main shaft needs to be potted.

[0003] In the existing technology, the common practice is to manually wrap the cup-shaped coil with a mold and then fill the bottom of the cup-shaped coil. However, this method is cumbersome when wrapping with a mold and cannot effectively and quickly hold the cup-shaped coil. Summary of the Invention

A pressing block is provided on the upper side of the side block for driving the pull rod to move downward. The two ends of the pressing block are inclined surfaces facing downward.

[0008] As a preferred embodiment of the present invention, the clamping assembly further includes a circular pressure block fixed to the edge of the turntable. A feeding support plate is provided on the side wall of the base and next to the lower pressure block. A hopper is provided above the feeding support plate. The inner cavity of the hopper is used to store the cup-shaped rotor. The bottom of the inner cavity of the hopper is inclined. A hopper opening communicating with the inner cavity of the hopper is provided on the side of the hopper and above the bottom inclined surface. A baffle one for covering the hopper opening is slidably provided at the bottom of the hopper. A baffle two is also slidably provided at the bottom of the hopper and next to the baffle one. A rotating slide plate is provided above the feeding support plate. A torsion spring is sleeved on the rotating shaft of the rotating slide plate. The two ends of the torsion spring are respectively connected to the rotating slide plate and the feeding support plate. Slide grooves are provided at both ends of the rotating slide plate. Slide rods are provided at the bottom of both the baffle one and the baffle two. The slide rods at the bottom of the baffle one and the baffle two are respectively inserted into the slide grooves at both ends of the rotating slide plate. A pressure rod that contacts the circular pressure block is provided on the side of the baffle two.

[0009] As a preferred embodiment of the present invention, the second station on the base includes a filling support plate fixedly disposed on the side wall of the base, and a filling machine for filling and sealing a cup-shaped rotor is disposed above the filling support plate.

[0010] As a preferred embodiment of the present invention, the third station on the base includes a drying support plate fixedly disposed on the side wall of the base, and a fan for drying the sealant on the cup-shaped rotor is also provided above the drying support plate.

[0011] As a preferred embodiment of the present invention, the side of the moving mold base is provided with a rocker plate, and the fourth station on the base includes a finished product bin fixedly disposed on the side wall of the base, and the finished product bin is provided with a lever for driving the rocker plate.

[0012] As a preferred embodiment of the present invention, a demolding frame is provided above the finished product warehouse, and a sloping pressure plate for driving the end of the cup-shaped rotor spindle is provided on the top of the demolding frame.

[0013] As a preferred technical solution of the present invention, the first station on the base also includes an additive support plate fixedly disposed on the side wall of the base, and the additive support plate is located between the feeding support plate and the finished product bin. A release agent machine is provided above the additive support plate, and the outlet valve of the release agent machine is connected to a pipe. An agent head is connected to the pipe, and both the upper and lower ends of the agent head are provided with an agent outlet hole.

[0014] The advantages of this invention compared to the prior art are:

[0015] (1) When the clamping assembly of the present invention begins to pass the first station on the base, the lower end of the push rod contacts the end inclined surface of the arc-shaped convex plate, the fixed mold base and the moving mold base rotate to the horizontal state, and at the same time the inclined surface of the lower pressure block drives the pull rod to move downward. The pull rod carries the rectangular slide and the insert rod to move downward synchronously. The insert rod presses the lever, causing the lever to rotate. The moving mold base rotates synchronously with the lever, and the moving mold base separates from the fixed mold base. At this time, the fixed mold base is located at the lower end of the inclined surface of the hopper, preparing for the insertion of the cup-shaped rotor.

[0016] (2) The circular pressure block of the clamping assembly of the present invention contacts the pressure rod. The circular pressure block drives the pressure rod to move to the lower position. The pressure rod carries the second baffle to the lower position. The sliding rod at the bottom of the second baffle slides in the groove of the rotating slide plate, causing the rotating slide plate to rotate, thereby causing the first baffle to move to the upper position synchronously. The first baffle prevents the cup-shaped rotor located in the inner cavity of the hopper from falling from the hopper opening. The cup-shaped rotor between the first baffle and the second baffle slides down the bottom slope of the hopper from the hopper opening and automatically falls onto the fixed mold base.

[0017] (3) The second tension spring of the present invention provides tension to close the fixed mold base and the moving mold base, that is, the fixed mold base and the moving mold base automatically clamp the cup-shaped rotor. At the same time, the first tension spring provides elasticity to keep the fixed mold base and the moving mold base clamping the cup-shaped rotor in a vertical state, with the bottom of the cup-shaped rotor facing upward. When the clamping assembly passes the second station on the base, the glue outlet of the potting machine faces the bottom of the cup-shaped rotor, the potting machine pots the bottom of the cup-shaped rotor, and the sealing block seals the fixed mold base and the moving mold base tightly, preventing the potting glue from flowing out from the gap between the fixed mold base and the moving mold base.

[0018] (4) When the clamping assembly of the present invention carries the already potted cup-shaped rotor through the third station on the base, the fan is started to accelerate the solidification of the potting compound.

[0019] (5) When the clamping assembly of the present invention carries the already potted and solidified cup-shaped rotor through the fourth station on the base, the rocker plate on the moving mold base contacts the push plate. As the turntable rotates, the push plate causes the lever and the moving mold base to rotate, the tension spring is stretched, and the fixed mold base and the moving mold base separate. Therefore, the cup-shaped rotor automatically falls from between the fixed mold base and the moving mold base into the finished product bin. At the same time, when the cup-shaped rotor passes the inclined pressure plate, the inclined pressure plate drives the cup-shaped rotor to move downward, so as to prevent the cup-shaped rotor from sticking to the fixed mold base and the moving mold base.

[0020] (6) When the clamping assembly of the present invention passes through the first station on the base, the fixed mold base and the moving mold base rotate to a horizontal state and the fixed mold base and the moving mold base separate, the fixed mold base and the moving mold base pass through the coating head, the coating head is located between the moving mold base and the tension spring, the additive support plate provides the release agent, the release agent passes through the through pipe and the coating head, and finally squeezes out from the discharge hole, thereby applying it to the inner wall surface of the fixed mold base and the moving mold base, so as to avoid the potting glue sticking to the inner wall of the fixed mold base and the moving mold base during potting.

[0042] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0043] Example 1: Please refer to Figures 1 to 18 Structural diagram; the present invention provides the following technical solution:

[0044] A hollow cup motor-driven filling device includes a base 1, a motor 2 mounted on the base 1, a drive gear 3 mounted on the rotating shaft of the motor 2, a driven gear 4 meshing beside the drive gear 3, a turntable 5 above the driven gear 4, and the driven gear 4 and the turntable 5 rotating together on the top of the base 1. The axis of the turntable 5 coincides with the axis of the base 1. Four sets of clamping components 6 are evenly arranged around the periphery of the turntable 5, and the angle formed by two adjacent sets of clamping components 6 relative to the center of the turntable 5 is 90 degrees. Four workstations are evenly arranged on the base 1, and the angle formed by two adjacent workstations relative to the center of the base 1 is 90 degrees. The motor 2 drives the drive gear 3 to rotate, the drive gear 3 drives the driven gear 4 to rotate, and the driven gear 4 drives the turntable 5 to rotate synchronously, so that the four sets of clamping components 6 on the turntable 5 sequentially circulate through the four workstations on the base 1.

[0045] The clamping assembly 6 includes a rotating base 601 fixedly mounted above the turntable 5. A rotating rod 602 is rotatably mounted on the upper part of the rotating base 601. A triangular support 603 is provided on the side of the rotating base 601. A tension spring 604 connects the triangular support 603 and the rotating rod 602. A stop bar 605 is provided on the rotating rod 602, which contacts the triangular support 603. A clamping groove is provided at the end of the rotating rod 602 away from the center of the turntable 5. A fixed mold base 606 is provided at the end of the clamping groove of the rotating rod 602. A lever 607 is rotatably mounted in the clamping groove of the rotating rod 602. A movable mold base 608 that cooperates with the fixed mold base 606 is provided at the end of the lever 607. The fixed mold base 606 and the lever 608... A tension spring 609 is connected between 07. A rectangular slide 610 is slidably provided on the turntable 5 outside the rotating rod 602. The top of the rectangular slide 610 is provided with a plug rod 611 for driving the lever 607 to rotate. The lower end of the rectangular slide 610 is provided with a pull rod 612. A swing rod 613 is provided at one end of the rotating rod 602 near the center of the turntable 5. A top rod 614 is slidably provided on the turntable 5 for driving the swing rod 613 to rotate. A retaining ring 615 for contacting the turntable 5 is provided in the middle of the swing rod 613. A spring 616 is sleeved on the outside of the top rod 614. The two ends of the spring 616 are connected to the lower end of the top rod 614 and the turntable 5, respectively.

[0046] In the initial state, when the clamping components 6 are not in any of the four positions, spring 616 provides elastic force, causing the ejector rod 614 to be in the lower position. At this time, the retaining ring 615 is in contact with the upper surface of the turntable 5, and the top of the ejector rod 614 is not in contact with the rocker arm 613. That is, under the tension provided by the tension spring 604, the stop rod 605 is in contact with the upper surface of the triangular support 603, and both the rocker arm 613 and the stop rod 605 are in a horizontal state. At this time, the axes of the fixed mold base 606 and the moving mold base 608 are both in a vertical state, and the clamping groove of the rotating rod 602 is also in a horizontal state. That is, the clamping groove of the rotating rod 602 does not coincide with the insertion rod 611, while the insertion rod 611 is in contact with the cylindrical surface of the rotating rod 602, causing the insertion rod 611 to be in the upper position. At the same time, tension spring 609 provides tension, keeping the fixed mold base 606 and the moving mold base 608 in a closed state, and sealing block 618 ensures a tight seal between the fixed mold base 606 and the moving mold base 608.

[0047] The first station on the base 1 includes an arc-shaped protrusion 8 fixedly installed above the base 1. The two ends of the arc-shaped protrusion 8 are inclined surfaces. The arc-shaped protrusion 8 is used to drive the top rod 614 to move upward. A side block 9 is provided on the base 1 and next to the arc-shaped protrusion 8. A lower pressing block 10 is provided on the upper side of the side block 9 to drive the pull rod 612 to move downward. The two ends of the lower pressing block 10 are inclined surfaces facing downward.

[0048] Specifically, when the clamping assembly 6 begins to pass the first station on the base 1, the lower end of the push rod 614 first contacts the inclined surface of the end of the arc-shaped protrusion 8, driving the push rod 614 to move upward. The spring 616 is compressed, and the upper end of the push rod 614 pushes the swing rod 613 to rotate, causing the swing rod 613 to rotate from a horizontal state to a vertical state. During this process, the tension spring 604 is stretched, and the swing rod 613, along with the stop rod 605, rotates to a vertical state. At the same time, the clamping groove on the rotating rod 602 rotates to a vertical state, causing the insert rod 611 to coincide with the clamping groove on the rotating rod 602, that is, the insert rod 611 contacts the lever 607. The fixed mold base 606 and the moving mold base 608 also rotate to a horizontal state with the rotating rod 602, and the fixed mold base 606 is located below the moving mold base 608.

[0049] As the clamping assembly 6 passes through the first station on the base 1, the lower end of the push rod 614 transitions from the inclined surface of the arc-shaped protrusion 8 to its upper surface. At the same time, the pull rod 612 contacts the inclined surface of the lower pressure block 10. The inclined surface of the lower pressure block 10 drives the pull rod 612 to move downward. The pull rod 612 moves downward synchronously with the rectangular slide 610 and the insert rod 611. The insert rod 611 presses the lever 607, causing the lever 607 to rotate. The tension spring 609 is stretched, and the moving mold base 608 rotates synchronously with the lever 607. The moving mold base 608 separates from the fixed mold base 606, making room for the cup-shaped rotor 7 to be inserted.

[0050] The clamping assembly 6 also includes a circular pressure block 619 fixed to the edge of the turntable 5. A feeding support plate 11 is provided on the side wall of the base 1, next to the lower pressure block 10. A hopper 12 is provided above the feeding support plate 11. The inner cavity of the hopper 12 is used to store the cup-shaped rotor 7. The bottom of the inner cavity of the hopper 12 is sloped. A hopper opening 1201 communicating with the inner cavity of the hopper 12 is provided on the side of the hopper 12, above the bottom slope. A baffle 13 for covering the hopper opening 1201 is slidably provided at the bottom of the hopper 12. A second baffle 14 is slidably provided on the side of the first baffle 13. A rotating slide plate 15 is provided above the feeding support plate 11. A torsion spring 16 is sleeved on the rotating shaft of the rotating slide plate 15. The two ends of the torsion spring 16 are respectively connected to the rotating slide plate 15 and the feeding support plate 11. The two ends of the rotating slide plate 15 are provided with sliding grooves. The bottom of the first baffle 13 and the second baffle 14 are both provided with sliding rods. The sliding rods at the bottom of the first baffle 13 and the second baffle 14 are respectively inserted into the sliding grooves at both ends of the rotating slide plate 15. The side of the second baffle 14 is provided with a pressure rod 17 that contacts the round pressure block 619. In its original state, the torsion spring 16 provides torsional force, causing the end of the rotating slide plate 15 near the base 1 to be tilted upward, that is, the first baffle 13 is in the lower position and the second baffle 14 is in the upper position. The second baffle 14 prevents all cup-shaped rotors 7 from falling from the opening 1201. The distance between the first baffle 13 and the second baffle 14 is set to be 1.1 to 1.2 times the diameter of the cup-shaped rotor 7.

[0051] Specifically, after the moving mold base 608 and the fixed mold base 606 separate, the fixed mold base 606 is located at the lower end of the inclined surface of the hopper 12. The circular pressure block 619 of the clamping assembly 6 begins to contact the pressure rod 17. The circular pressure block 619 drives the pressure rod 17 to move to the lower position. The pressure rod 17 moves the baffle 2 14 to the lower position. The sliding rod at the bottom of the baffle 2 14 slides in the groove of the rotating slide plate 15, causing the rotating slide plate 15 to rotate. This causes the baffle 1 13 to move synchronously to the upper position. The baffle 1 13 prevents the cup-shaped rotor 7 located in the inner cavity of the hopper 12 from falling from the hopper opening 1201. The cup-shaped rotor 7 between the baffle 1 13 and the baffle 2 14 slides down the bottom inclined surface of the hopper 12 from the hopper opening 1201 and falls onto the fixed mold base 606.

[0052] When the clamping assembly 6 leaves the first station, the circular pressure block 619 first separates from the pressure rod 17, and the torsion spring 16 provides torsional force, causing the rotating slide plate 15 to rotate in the opposite direction, and the second baffle 14 moves back to the upper position. Then, the pull rod 612 separates from the lower pressure block 10, and the second tension spring 609 provides tension, causing the lever 607 to rotate in the opposite direction, and the fixed mold base 606 and the moving mold base 608 close, that is, the fixed mold base 606 and the moving mold base 608 clamp the cup-shaped rotor 7. Finally, the lower end of the ejector rod 614 separates from the arc-shaped protrusion 8, the first spring 616 provides elastic force, causing the ejector rod 614 to move back to the lower position, and the first tension spring 604 provides elastic force, causing the rotating rod 602 to rotate in the opposite direction. The fixed mold base 606 and the moving mold base 608 clamp the cup-shaped rotor 7 in a vertical state, and the bottom of the cup-shaped rotor 7 faces upward, so as to perform potting.

[0053] To prevent the cup-shaped rotor 7 from falling between the fixed mold base 606 and the moving mold base 608, anti-slip blocks 617 are provided at the bottom of both the fixed mold base 606 and the moving mold base 608 to prevent the cup-shaped rotor 7 from sliding down. The anti-slip blocks 617 are provided with arc-shaped inclined surfaces.

[0054] The second station on the base 1 includes a filling support plate 18 fixedly installed on the side wall of the base 1, and a filling machine 19 for filling and sealing the cup-shaped rotor 7 is provided above the filling support plate 18.

[0055] Specifically, when the clamping assembly 6 passes the second station on the base 1, the dispensing hole of the potting machine 19 is directly above the moving mold base 608 and the fixed mold base 606, that is, the dispensing hole of the potting machine 19 is facing the bottom of the cup-shaped rotor 7, and the potting machine 19 pots the bottom of the cup-shaped rotor 7. Both sides of the fixed mold base 606 are provided with sealing blocks 618 that seal with the moving mold base 608, ensuring a tight seal between the fixed mold base 606 and the moving mold base 608, preventing the potting compound from flowing out from the gap between the fixed mold base 606 and the moving mold base 608.

[0056] The third station on the base 1 includes a drying support plate 20 fixedly installed on the side wall of the base 1, and a fan 21 for drying the sealant on the cup-shaped rotor 7 is also provided above the drying support plate 20.

[0057] Specifically, when the clamping assembly 6 carries the already potted cup-shaped rotor 7 past the third station on the base 1, the blower 21 is started to accelerate the solidification of the potting compound.

[0058] The moving mold base 608 has a rocker plate 620 on its side. The fourth station on the base 1 includes a finished product compartment 22 fixedly installed on the side wall of the base 1. The finished product compartment 22 is provided with a lever plate 23 for driving the rocker plate 620.

[0059] Specifically, when the clamping assembly 6, carrying the already potted and solidified cup-shaped rotor 7, passes through the fourth station on the base 1, the moving mold base 608 is still in a vertical state, and the rocker arm 620 on the moving mold base 608 is in contact with the lever 23. As the turntable 5 rotates, the lever 23 causes the lever 607 and the moving mold base 608 to rotate, the tension spring 609 is stretched, and the fixed mold base 606 and the moving mold base 608 separate. Therefore, the cup-shaped rotor 7 falls from between the fixed mold base 606 and the moving mold base 608 into the finished product bin 22. The arc-shaped slope on the anti-slip block 617 prevents the anti-slip block 617 from getting stuck on the cup-shaped rotor 7. As the clamping assembly 6 passes through the fourth station on the base 1, the lever 23 separates from the rocker arm 620, and under the action of the tension spring 609, the clamping assembly 6 returns to its original state.

[0060] To prevent the cup-shaped rotor 7 from sticking to the fixed mold base 606 and the moving mold base 608 when they are opened, thus preventing it from falling into the finished product bin 22, a demolding frame 24 is provided above the finished product bin 22. The top of the demolding frame 24 is provided with an inclined pressure plate 25 for driving the end of the main shaft of the cup-shaped rotor 7. When the cup-shaped rotor 7 passes the inclined pressure plate 25, the inclined pressure plate 25 drives the cup-shaped rotor 7 to move downward, thereby causing the cup-shaped rotor 7 to fall into the finished product bin 22.

[0061] The working principle of this embodiment is as follows: the motor 2 drives the drive gear 3 to rotate, the drive gear 3 drives the driven gear 4 to rotate, and the driven gear 4 drives the turntable 5 to rotate synchronously, so that the four sets of clamping components 6 on the turntable 5 pass through the four workstations on the base 1 in sequence. When the clamping components 6 pass through the four workstations on the base 1, the motor 2 stops rotating intermittently.

[0062] In the initial state, when the clamping components 6 are not in the four positions, spring 616 provides elastic force, causing the ejector rod 614 to be in the lower position. At this time, the retaining ring 615 is in contact with the upper surface of the turntable 5, and the top of the ejector rod 614 is not in contact with the rocker arm 613. That is, under the tension of spring 604, the stop rod 605 is in contact with the upper surface of the triangular support 603, and both the rocker arm 613 and the stop rod 605 are in a horizontal state. At this time, the axes of the fixed mold base 606 and the moving mold base 608 are both in a vertical state, and the clamping groove of the rotating rod 602 is also in a horizontal state. That is, the clamping groove of the rotating rod 602 does not coincide with the insertion rod 611, while the insertion rod 611 is in contact with the cylindrical surface of the rotating rod 602, causing the insertion rod 611 to be in the upper position. At the same time, tension spring 609 provides tension, causing the fixed mold base 606 and the moving mold base 608 to be in a closed state.

[0063] When the clamping assembly 6 begins to pass the first station on the base 1, the lower end of the push rod 614 first contacts the inclined end of the arc-shaped protrusion 8, driving the push rod 614 to move upward. The spring 616 is compressed, and the upper end of the push rod 614 pushes the swing rod 613 to rotate, causing the swing rod 613 to rotate from a horizontal state to a vertical state. During this process, the tension spring 604 is stretched, and the swing rod 613, along with the stop rod 605, rotates to a vertical state. At the same time, the clamping groove on the rotating rod 602 rotates to a vertical state, causing the insert rod 611 to coincide with the clamping groove on the rotating rod 602, that is, the insert rod 611 contacts the lever 607. The fixed mold base 606 and the moving mold base 608 also rotate to a horizontal state with the rotating rod 602, and the fixed mold base 606 is located below the moving mold base 608.

[0064] As the clamping assembly 6 passes through the first station on the base 1, the lower end of the push rod 614 transitions from the inclined surface of the arc-shaped convex plate 8 to its upper surface. At the same time, the pull rod 612 contacts the inclined surface of the lower pressure block 10. The inclined surface of the lower pressure block 10 drives the pull rod 612 to move downward. The pull rod 612 moves downward synchronously with the rectangular slide 610 and the insert rod 611. The insert rod 611 presses the lever 607, causing the lever 607 to rotate. The tension spring 609 is stretched, and the moving mold base 608 rotates synchronously with the lever 607. The moving mold base 608 separates from the fixed mold base 606. At this time, the fixed mold base 606 is located at the lower end of the inclined surface of the hopper 12. The circular pressure block 619 of the clamping assembly 6 begins to contact the pressure rod 17. The circular pressure block 619 drives the pressure rod 17 to move to the lower position. The pressure rod 17 moves the second baffle 14 to the lower position. The sliding rod at the bottom of the second baffle 14 slides in the groove of the rotating slide plate 15, causing the rotating slide plate 15 to rotate. This causes the first baffle 13 to move to the upper position synchronously. The first baffle 13 prevents the cup-shaped rotor 7 located in the inner cavity of the hopper 12 from falling from the hopper opening 1201. The cup-shaped rotor 7 between the first baffle 13 and the second baffle 14 slides down the bottom slope of the hopper 12 from the hopper opening 1201 and falls onto the fixed mold base 606.

[0065] When the clamping assembly 6 leaves the first station, the circular pressure block 619 first separates from the pressure rod 17, and the torsion spring 16 provides torsional force, causing the rotating slide plate 15 to rotate in the opposite direction, and the second baffle 14 moves back to the upper position. Then the pull rod 612 separates from the lower pressure block 10, and the second tension spring 609 provides tension, causing the lever 607 to rotate in the opposite direction, and the fixed mold base 606 and the moving mold base 608 close, that is, the fixed mold base 606 and the moving mold base 608 automatically clamp the cup-shaped rotor 7. Finally, the lower end of the ejector rod 614 separates from the arc-shaped protrusion 8, the first spring 616 provides elastic force, causing the ejector rod 614 to move back to the lower position, and the first tension spring 604 provides elastic force, causing the rotating rod 602 to rotate in the opposite direction. The fixed mold base 606 and the moving mold base 608 clamp the cup-shaped rotor 7 in a vertical state, and the bottom of the cup-shaped rotor 7 faces upward, so as to perform potting. To prevent the cup-shaped rotor 7 from falling between the fixed mold base 606 and the moving mold base 608, anti-slip blocks 617 are provided at the bottom of both the fixed mold base 606 and the moving mold base 608 to prevent the cup-shaped rotor 7 from sliding down. The anti-slip blocks 617 are provided with arc-shaped inclined surfaces.

[0066] When the clamping assembly 6 passes the second station on the base 1, the dispensing hole of the potting machine 19 is directly above the moving mold base 608 and the fixed mold base 606, that is, the dispensing hole of the potting machine 19 is facing the bottom of the cup-shaped rotor 7, and the potting machine 19 pots the bottom of the cup-shaped rotor 7. Both sides of the fixed mold base 606 are provided with sealing blocks 618 that seal with the moving mold base 608, so that the fixed mold base 606 and the moving mold base 608 are tightly sealed, preventing the potting glue from flowing out from the gap between the fixed mold base 606 and the moving mold base 608.

[0067] When the clamping assembly 6 carries the already potted cup-shaped rotor 7 past the third station on the base 1, the blower 21 is started to accelerate the solidification of the potting compound.

[0068] When the clamping assembly 6 carries the already potted and solidified cup-shaped rotor 7 past the fourth station on the base 1, the moving mold base 608 is still in a vertical position, and the rectangular slide 610 on the moving mold base 608 is in contact with the lever 23. As the turntable 5 rotates, the lever 23 causes the lever 607 and the moving mold base 608 to rotate, the tension spring 609 is stretched, and the fixed mold base 606 and the moving mold base 608 separate. Therefore, the cup-shaped rotor 7 falls from between the fixed mold base 606 and the moving mold base 608 into the finished product bin 22. The arc-shaped slope on the anti-slip block 617 prevents the anti-slip block 617 from getting stuck on the cup-shaped rotor 7. At the same time, when the cup-shaped rotor 7 passes the inclined pressure plate 25, the inclined pressure plate 25 drives the cup-shaped rotor 7 to move downward, preventing the cup-shaped rotor 7 from sticking to the fixed mold base 606 and the moving mold base 608, so that the cup-shaped rotor 7 falls smoothly into the finished product bin 22.

[0069] By repeating the above process, the bottom of the cup-shaped rotor 7 can be continuously potted.

[0070] Example 2: Please refer to Figures 19 to 20The structural diagram shows that, based on specific embodiment one, this embodiment differs in the following ways:

[0071] The first station on the base 1 also includes an additive support plate 26 fixedly installed on the side wall of the base 1, and the additive support plate 26 is located between the feeding support plate 11 and the finished product hopper 22. A release agent machine 27 is provided above the additive support plate 26. The outlet valve of the release agent machine 27 is connected to a pipe 28. An agent head 29 is connected to the pipe 28. Both the upper and lower ends of the agent head 29 are provided with an agent outlet hole 2901.

[0072] When the clamping assembly 6 passes the first station on the base 1, the fixed mold base 606 and the moving mold base 608 rotate to a horizontal state and separate. The fixed mold base 606 and the moving mold base 608 pass through the coating head 29, which is located between the moving mold base 608 and the tension spring 609. The additive support plate 26 provides the release agent. The release agent passes through the tube 28 and the coating head 29 and is finally squeezed out from the outlet hole 2901, thereby applying it to the inner wall surface of the fixed mold base 606 and the moving mold base 608. This prevents the potting compound from sticking to the inner wall of the fixed mold base 606 and the moving mold base 608 during potting.
