[0002] Coreless motors are a type of motor that utilizes an ironless rotor structure. They offer significant advantages such as high efficiency, high power density, and low moment of inertia, demonstrating irreplaceable application value in precision control, aerospace, and medical equipment. Coreless motor rotors are hollow cup-shaped rotors composed of self-supporting cup-shaped coils. The wires of the cup-shaped coils extend to the motor's main shaft. To strengthen the connection between the cup-shaped coils and the main shaft, the joint between the cup-shaped coils and the main shaft must be potted. Specifically, the mating circular surface between the bottom of the cup-shaped coil and the main shaft must be potted.

[0003] In the prior art, a common practice is to manually wrap the cup-shaped coil using a mold and then potting the bottom of the cup-shaped coil.

[0014] The beneficial effects of the present invention compared with the prior art are: (1) When the clamping assembly of the present invention begins to pass through the first station on the base, the lower end of the push rod contacts the end inclined surface of the arc-shaped convex plate, and the fixed mold base and the movable mold base rotate to a horizontal state. At the same time, the inclined surface of the lower pressure block drives the pull rod to move downward, and the pull rod moves downward synchronously with the rectangular slide and the insertion rod. The insertion rod presses the lever to rotate the lever, and the movable mold base rotates synchronously with the lever. The movable mold base is separated 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, ready for the cup-shaped rotor to be placed.

[0015] (2) The circular pressure block of the clamping assembly of the present invention contacts the pressure rod, and the circular pressure block drives the pressure rod to move to the lower position. The pressure rod moves baffle 2 to the lower position, and the sliding bar at the bottom of baffle 2 slides in the sliding groove of the rotating slide plate, causing the rotating slide plate to rotate, thereby causing baffle 1 to move to the upper position synchronously. Baffle 1 prevents the cup-shaped rotor located in the inner cavity of the silo from falling from the silo opening, while the cup-shaped rotor between baffles 1 and 2 slides from the silo opening along the bottom inclined surface of the silo and automatically falls onto the fixed mold base.

[0016] (3) The second tension spring of the present invention provides a tensile force to close the fixed mold base and the movable mold base, that is, the fixed mold base and the movable mold base automatically clamp the cup-shaped rotor. At the same time, the first tension spring provides an elastic force to keep the fixed mold base and the movable 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, and the potting machine pots the bottom of the cup-shaped rotor, and the sealing block seals the fixed mold base and the movable mold base tightly, preventing the potting glue from flowing out of the gap between the fixed mold base and the movable mold base.

[0017] (4) When the clamping assembly of the present invention carries the potted cup-shaped rotor through the third station on the base, the fan is started to accelerate the solidification of the potting glue.

[0018] (5) When the clamping assembly of the present invention carries the potted and solidified cup-shaped rotor through the fourth station on the base, the rocker plate on the movable mold seat contacts the paddle plate. As the turntable rotates, the paddle plate causes the lever and the movable mold seat to rotate, the tension spring 2 is stretched, and the fixed mold seat and the movable mold seat are separated. Therefore, the cup-shaped rotor automatically falls from between the fixed mold seat and the movable mold seat into the finished product bin. At the same time, when the cup-shaped rotor passes through the inclined pressure plate, the inclined pressure plate drives the cup-shaped rotor to move downward to prevent the cup-shaped rotor from sticking to the fixed mold seat and the movable mold seat.

[0019] (6) The clamping assembly of the present invention passes through the first station on the base, the fixed mold base and the movable mold base rotate to a horizontal state, and when the fixed mold base and the movable mold base are separated, the fixed mold base and the movable mold base pass through the coating head, the coating head is located between the movable mold base and the second tension spring, the additive support plate provides a demolding agent, the demolding agent passes through the through pipe and the coating head, and is finally squeezed out from the agent outlet, thereby being smeared on the inner wall surface of the fixed mold base and the movable mold base, thereby preventing the potting glue from adhering to the inner wall of the fixed mold base and the movable mold base during potting.

DETAILED DESCRIPTION

[0041] Example 1: Please refer to Figures 1 to 18 Structural schematic diagram, the present invention provides the following technical solutions: A hollow cup motor potting device includes a base 1. The base 1 is provided with a motor 2. The rotating shaft of the motor 2 is provided with a driving gear 3. A driven gear 4 is meshed with the driving gear 3. A turntable 5 is provided above the driven gear 4. The driven gear 4 and the turntable 5 rotate together and are arranged on the top of the base 1. The axis of the turntable 5 coincides with the axis of the base 1. Four groups of clamping assemblies 6 are evenly arranged around the circumference of the turntable 5, and the angle formed by two adjacent groups of clamping assemblies 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 groups of clamping assemblies 6 relative to the center of the base 1 is 90 degrees. The motor 2 drives the driving gear 3 to rotate, and the driving gear 3 drives the driven gear 4 to rotate. The driven gear 4 rotates synchronously with the turntable 5, so that the four groups of clamping assemblies 6 on the turntable 5 circulate through the four workstations on the base 1 in sequence.

[0042] The clamping assembly 6 includes a swivel seat 601 fixedly arranged above the turntable 5, a swivel rod 602 rotatably provided on the upper part of the swivel seat 601, a triangular support 603 provided on the side of the swivel seat 601, a tension spring 604 connected between the triangular support 603 and the swivel rod 602, a stopper rod 605 in contact with the triangular support 603 provided on the swivel rod 602, a clamping groove provided on the end of the clamping groove of the swivel rod 602 away from the center of the turntable 5, a fixed die seat 606 provided at the end of the clamping groove of the swivel rod 602, a lever 607 rotatably provided in the clamping groove of the swivel rod 602, a movable die seat 608 cooperating with the fixed die seat 606, and the fixed die seat 606 and the lever 607 are connected. 07 is connected with a tension spring 2 609, a rectangular slide 610 is slidably provided on the turntable 5 and located outside the rotating rod 602, the top of the rectangular slide 610 is provided with an insertion rod 611 for driving the lever 607 to rotate, and the lower end of the rectangular slide 610 is provided with a pull rod 612, and the end of the rotating rod 602 close to the center of the turntable 5 is provided with a rocker rod 613, and a top rod 614 for driving the rocker rod 613 to rotate is slidably provided on the turntable 5, and a retaining ring 615 for contacting the turntable 5 is provided in the middle of the rocker rod 613, and a spring 1 616 is provided on the outside of the top rod 614, and the two ends of the spring 1 616 are respectively connected with the lower end of the top rod 614 and the turntable 5.

[0043] In the initial state, i.e., when none of the clamping assemblies 6 are in the four working positions, spring 1 616 provides an elastic force, keeping the push rod 614 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 push rod 614 is not in contact with the rocker arm 613. That is, under the tension provided by tension spring 1 604, the retaining rod 605 is in contact with the upper surface of the triangular support 603, and the rocker arm 613 and retaining rod 605 are both in a horizontal position. At this time, the axes of the fixed mold base 606 and the movable mold base 608 are both in a vertical position, and the clamping groove of the rotating rod 602 is also in a horizontal position. That is, the clamping groove of the rotating rod 602 does not overlap with the insertion rod 611, and the insertion rod 611 is in contact with the cylindrical surface of the rotating rod 602, so that the insertion rod 611 is in the upper position. At the same time, the second tension spring 609 provides tension to keep the fixed mold base 606 and the movable mold base 608 in a closed state, and the sealing block 618 ensures a tight seal between the fixed mold base 606 and the movable mold base 608.

[0044] The first workstation on the base 1 includes an arc-shaped protruding plate 8 fixed on the top of the base 1, and the two ends of the arc-shaped protruding plate 8 are inclined surfaces. The arc-shaped protruding plate 8 is used to drive the top rod 614 to move upward. A side block 9 is provided on the base 1 and located on the side of the arc-shaped protruding plate 8. A lower pressing block 10 for driving the pull rod 612 to move downward is provided on the upper side of the side block 9, and the two ends of the lower pressing block 10 are inclined surfaces facing downward.

[0045] Specifically, when the clamping assembly 6 begins to pass through 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 protruding plate 8, driving the push rod 614 upward. Spring 1 616 compresses, and the upper end of the push rod 614 rotates against the rocker 613, causing the rocker 613 to rotate from a horizontal position to a vertical position. During this process, the tension spring 1 604 stretches, causing the rocker 613 to rotate to a vertical position with the stopper 605. Simultaneously, the clamping groove on the rotating rod 602 rotates to a vertical position, causing the insertion rod 611 to overlap with the clamping groove on the rotating rod 602, that is, the insertion rod 611 contacts the lever 607. The fixed mold base 606 and the movable mold base 608 also rotate to a horizontal position along with the rotating rod 602, with the fixed mold base 606 located below the movable mold base 608.

[0046] As the clamping assembly 6 then passes through the first workstation 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, and 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, and the pull rod 612 moves downward synchronously with the rectangular slide 610 and the insertion rod 611. The insertion rod 611 presses the lever 607 to rotate the lever 607, and the tension spring 609 is stretched. The movable mold base 608 rotates synchronously with the lever 607, and the movable mold base 608 is separated from the fixed mold base 606 to make room for the cup-shaped rotor 7.

[0047] The clamping assembly 6 also includes a round pressing block 619 fixed to the edge of the turntable 5. A loading support plate 11 is provided on the side wall of the base 1 and is located next to the lower pressing block 10. A hopper 12 is provided above the loading 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 an inclined surface. A hopper opening 1201 communicating with the inner cavity of the hopper 12 is provided on the side of the hopper 12 and is located above the bottom inclined surface. A baffle 13 for covering the hopper opening 1201 is provided on the bottom of the hopper 12. A baffle 2 14 is also slidably provided on the side of baffle 13, and a rotating slide plate 15 is provided above the loading support plate 11. A torsion spring 16 is sleeved on the rotating shaft of the rotating slide plate 15, and the two ends of the torsion spring 16 are respectively connected to the rotating slide plate 15 and the loading support plate 11. A slide groove is provided at both ends of the rotating slide plate 15, and a slide rod is provided at the bottom of baffle 13 and baffle 2 14. The slide rods at the bottom of baffle 13 and baffle 2 14 are respectively inserted into the slide grooves at both ends of the rotating slide plate 15, and a pressure rod 17 in contact with the round pressure block 619 is provided on the side of baffle 2 14. In the original state, the torsion spring 16 provides a torsional force, so that the end of the rotating slide plate 15 close to the base 1 is in an upward tilted state, that is, baffle 13 is in the lower position, and baffle 2 14 is in the upper position. Baffle 2 14 prevents all cup-shaped rotors 7 from falling from the warehouse opening 1201, and the distance between baffle 1 13 and baffle 2 14 is set to be in the range of 1.1 times to 1.2 times the diameter of the cup-shaped rotor 7.

[0048] Specifically, when the movable mold base 608 and the fixed mold base 606 are separated, the fixed mold base 606 is located at the lower end of the inclined surface of the silo 12, and 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, and the pressure rod 17 moves to the lower position with the baffle 2 14. The sliding rod at the bottom of the baffle 2 14 slides in the sliding groove of the rotating slide 15, causing the rotating slide 15 to rotate, thereby causing the baffle 13 to move to the upper position synchronously. The baffle 13 prevents the cup-shaped rotor 7 located in the inner cavity of the silo 12 from falling from the silo opening 1201, and the cup-shaped rotor 7 between the baffle 13 and the baffle 2 14 slides from the silo opening 1201 along the bottom inclined surface of the silo 12 and falls onto the fixed mold base 606.

[0049] 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 a torsional force, causing the rotating slide 15 to rotate in the opposite direction, and the second baffle 14 to move back to the upper position. Subsequently, the pull rod 612 separates from the lower pressure block 10, and the tension spring 2 609 provides a pulling force, causing the lever 607 to rotate in the opposite direction, and the fixed mold base 606 and the movable mold base 608 close, that is, the fixed mold base 606 and the movable mold base 608 clamp the cup-shaped rotor 7. Finally, the lower end of the push rod 614 separates from the arc-shaped convex plate 8, and the spring 1 616 provides an elastic force to move the push rod 614 back to the lower position, while the tension spring 1 604 provides an elastic force to cause the rotating rod 602 to rotate in the opposite direction. The fixed mold base 606 and the movable mold base 608 clamp the cup-shaped rotor 7 in a vertical state, with the bottom of the cup-shaped rotor 7 facing upward for potting.

[0050] In order to prevent the cup-shaped rotor 7 from falling from between the fixed mold base 606 and the movable mold base 608, anti-sliding blocks 617 are provided at the bottom of the fixed mold base 606 and the movable mold base 608 to prevent the cup-shaped rotor 7 from sliding down. The anti-sliding blocks 617 are provided with arc inclined surfaces.

[0051] The second workstation on the base 1 includes a potting support plate 18 fixed to the side wall of the base 1 , and a potting machine 19 for potting the cup-shaped rotor 7 is provided above the potting support plate 18 .

[0052] Specifically, when the clamping assembly 6 passes the second station on the base 1, the glue outlet of the potting machine 19 faces the upper portion of the movable mold base 608 and the fixed mold base 606. That is, the glue outlet of the potting machine 19 faces the bottom of the cup-shaped rotor 7, and the potting machine 19 pots the bottom of the cup-shaped rotor 7. Sealing blocks 618 are provided on both sides of the fixed mold base 606 to seal against the movable mold base 608. This ensures a tight seal between the fixed mold base 606 and the movable mold base 608, preventing the potting glue from flowing out of the gap between the fixed mold base 606 and the movable mold base 608.

[0053] The third workstation on the base 1 includes an air-drying support plate 20 fixed to 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 air-drying support plate 20 .

[0054] Specifically, when the clamping assembly 6 carries the potted cup-shaped rotor 7 through the third workstation on the base 1 , the fan 21 is started to accelerate the solidification of the potting glue.

[0055] A rocker plate 620 is provided on the side of the movable mold base 608 . The fourth workstation on the base 1 includes a finished product bin 22 fixed to the side wall of the base 1 . The finished product bin 22 is provided with a dial plate 23 for driving the rocker plate 620 .

[0056] Specifically, when the clamping assembly 6 carries the potted and solidified cup-shaped rotor 7 through the fourth station on the base 1, the movable mold base 608 is still in a vertical position, and the rocker plate 620 on the movable mold base 608 contacts the paddle plate 23. As the turntable 5 rotates, the paddle plate 23 causes the lever 607 and the movable mold base 608 to rotate, and the tension spring 609 is stretched, separating the fixed mold base 606 and the movable mold base 608. As a result, the cup-shaped rotor 7 falls from between the fixed mold base 606 and the movable mold base 608 into the finished product bin 22. The arc-shaped inclined surface 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 the fourth station on the base 1, the paddle plate 23 separates from the rocker plate 620, and under the action of the tension spring 609, the clamping assembly 6 returns to its original state.

[0057] In order to prevent the cup-shaped rotor 7 from sticking to the fixed mold base 606 and the movable mold base 608 when the fixed mold base 606 and the movable mold base 608 are opened and 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 main shaft end of the cup-shaped rotor 7. When the cup-shaped rotor 7 passes through 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.

[0058] The working principle of this embodiment is as follows: the motor 2 drives the driving gear 3 to rotate, the driving gear 3 drives the driven gear 4 to rotate, and the driven gear 4 rotates synchronously with the turntable 5, so that the four groups of clamping assemblies 6 on the turntable 5 circulate through the four stations on the base 1 in sequence, and when the clamping assemblies 6 pass through the four stations on the base 1, the motor 2 stops rotating intermittently.

[0059] In the initial state, i.e., when none of the clamping assemblies 6 are in the four working positions, spring 1 616 provides elastic force, keeping push rod 614 in the lower position. At this point, retaining ring 615 contacts the upper surface of turntable 5, and the top of push rod 614 does not contact rocker 613. Specifically, under the tension provided by tension spring 1 604, retaining rod 605 contacts the upper surface of triangular support 603, and rocker 613 and retaining rod 605 are both horizontal. At this point, the axes of fixed mold base 606 and movable mold base 608 are both vertical, and the clamping groove of rotating rod 602 is also horizontal. Specifically, the clamping groove of rotating rod 602 does not overlap with insertion rod 611, and insertion rod 611 contacts the cylindrical surface of rotating rod 602, keeping insertion rod 611 in the upper position. Simultaneously, tension spring 2 609 provides tension, keeping fixed mold base 606 and movable mold base 608 in a closed position.

[0060] When the clamping assembly 6 begins to pass through 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 protruding plate 8, driving the push rod 614 upward. Spring 1 616 compresses, and the upper end of the push rod 614 rotates against the rocker 613, causing it to rotate from a horizontal position to a vertical position. During this process, the tension spring 1 604 stretches, causing the rocker 613 to rotate to a vertical position with the stopper 605. Simultaneously, the clamping groove on the rotating rod 602 rotates to a vertical position, causing the insertion rod 611 to overlap with the clamping groove on the rotating rod 602, that is, the insertion rod 611 contacts the lever 607. The fixed mold base 606 and the movable mold base 608 also rotate to a horizontal position along with the rotating rod 602, with the fixed mold base 606 located below the movable mold base 608.

[0061] As the clamping assembly 6 then passes through the first workstation 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, and 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, and the pull rod 612 moves downward synchronously with the rectangular slide 610 and the insertion rod 611. The insertion rod 611 presses the lever 607 to rotate the lever 607, and the tension spring 609 is stretched. The movable mold base 608 rotates synchronously with the lever 607, and the movable mold base 608 is separated 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, and the circular pressure block 619 drives the pressure rod 17 to move to the lower position. The pressure rod 17 moves to the lower position with the baffle 2 14, and the sliding rod at the bottom of the baffle 2 14 slides in the sliding groove of the rotating slide 15, causing the rotating slide 15 to rotate, thereby causing the baffle 13 to move to the upper position synchronously. The baffle 13 prevents the cup-shaped rotor 7 located in the inner cavity of the silo 12 from falling from the silo opening 1201, and the cup-shaped rotor 7 between the baffle 13 and the baffle 2 14 slides from the silo opening 1201 along the bottom inclined surface of the silo 12 and falls onto the fixed mold base 606.

[0062] 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 a torsional force, causing the rotating slide 15 to rotate in the opposite direction, and the second baffle 14 to move back to the upper position. Subsequently, the pull rod 612 separates from the lower pressure block 10, and the tension spring 2 609 provides a pulling force, causing the lever 607 to rotate in the opposite direction, and the fixed mold base 606 and the movable mold base 608 close, that is, the fixed mold base 606 and the movable mold base 608 automatically clamp the cup-shaped rotor 7. Finally, the lower end of the push rod 614 separates from the arc-shaped convex plate 8, and the spring 1 616 provides an elastic force to move the push rod 614 back to the lower position, while the tension spring 1 604 provides an elastic force to cause the rotating rod 602 to rotate in the opposite direction. The fixed mold base 606 and the movable mold base 608 clamp the cup-shaped rotor 7 in a vertical state, with the bottom of the cup-shaped rotor 7 facing upward for potting. In order to prevent the cup-shaped rotor 7 from falling from between the fixed mold base 606 and the movable mold base 608, anti-sliding blocks 617 are provided at the bottom of the fixed mold base 606 and the movable mold base 608 to prevent the cup-shaped rotor 7 from sliding down. The anti-sliding blocks 617 are provided with arc inclined surfaces.

[0063] When the clamping assembly 6 passes the second station on the base 1, the glue outlet of the potting machine 19 faces the top of the movable mold base 608 and the fixed mold base 606. That is, the glue outlet of the potting machine 19 faces the bottom of the cup-shaped rotor 7, and the potting machine 19 pots the bottom of the cup-shaped rotor 7. The fixed mold base 606 is provided with sealing blocks 618 on both sides, which seal with the movable mold base 608. This ensures a tight seal between the fixed mold base 606 and the movable mold base 608 and prevents the potting glue from flowing out of the gap between the fixed mold base 606 and the movable mold base 608.

[0064] When the clamping assembly 6 carries the potted cup-shaped rotor 7 through the third station on the base 1 , the fan 21 is started to accelerate the solidification of the potting glue.

[0065] When the clamping assembly 6 carries the potted and solidified cup-shaped rotor 7 through the fourth station on the base 1, the movable mold base 608 is still in a vertical position, and the rectangular slide 610 on the movable mold base 608 contacts the paddle 23. As the turntable 5 rotates, the paddle 23 causes the lever 607 and the movable mold base 608 to rotate, and the tension spring 2 609 is stretched, separating the fixed mold base 606 and the movable mold base 608. As a result, the cup-shaped rotor 7 falls from between the fixed mold base 606 and the movable mold base 608 into the finished product bin 22. The arc-shaped inclined surface on the anti-sliding plate 617 prevents the anti-sliding plate 617 from getting stuck on the cup-shaped rotor 7. At the same time, when the cup-shaped rotor 7 passes through the inclined plate 25, the inclined plate 25 drives the cup-shaped rotor 7 downward, preventing the cup-shaped rotor 7 from sticking to the fixed mold base 606 and the movable mold base 608, thereby allowing the cup-shaped rotor 7 to fall smoothly into the finished product bin 22.

[0066] The above process is repeated cyclically to continuously pot and seal the bottom of the cup-shaped rotor 7 .

[0067] Example 2: Please refer to Figures 19 to 20Structural diagram, based on the specific embodiment 1, the difference of this embodiment is: The first workstation on the base 1 also includes an additive support plate 26 fixed to the side wall of the base 1, and the additive support plate 26 is located between the loading support plate 11 and the finished product bin 22. A demolding agent machine 27 is provided above the additive support plate 26, and the outlet valve of the demolding agent machine 27 is connected to a through pipe 28, and a coating head 29 is provided on the through pipe 28. The coating head 29 has an agent outlet hole 2901 at both ends.

[0068] When the clamping assembly 6 passes the first workstation on the base 1, the fixed mold base 606 and the movable mold base 608 rotate to a horizontal state, and the fixed mold base 606 and the movable mold base 608 separate, the fixed mold base 606 and the movable mold base 608 pass through the coating head 29, and the coating head 29 is located between the movable mold base 608 and the tension spring 2 609. The additive support plate 26 provides a demolding agent, and the demolding agent passes through the through pipe 28 and the coating head 29, and is finally squeezed out from the agent outlet 2901, thereby being smeared on the inner wall surface of the fixed mold base 606 and the movable mold base 608, so as to avoid the potting glue sticking to the inner wall of the fixed mold base 606 and the movable mold base 608 during potting.
