Description

Technical Field

[0001] This utility model belongs to the technical field of hollow cup motor coil manufacturing equipment, and particularly relates to a ring-shaped movable snap-fit ​​station type arc-shaped sheet-shaped rhomboid coil positioning and ejection device. Background Technology

[0002] The coil of a coreless motor is the core component of the motor, and the quality of its manufacturing process directly affects the overall performance of the motor.

[0003] Coreless motor coils involve various manufacturing processes. One key technique is stacking and rolling multiple rhomboid sheet coils into a circle, which effectively increases the number of turns and inductance, optimizes the magnetic circuit structure, and improves the motor's output power and torque density. Simultaneously, this method helps improve the coil's heat dissipation, reducing performance degradation caused by heat and meeting the demands of high-end applications for long-term stable motor operation. Therefore, achieving the stacking and rolling of multiple rhomboid sheet coils in a coreless motor has become a key technological direction for improving motor performance.

[0004] In existing technology, equipment for "stacking and rolling multiple hollow cup motor rhomboid sheet coils" includes: a stacking fixture, a rough rolling device, and a fine rolling device. The stacking fixture includes a flat support plate and positioning posts sequentially fixed to the support plate. The distance between adjacent positioning posts is equal, and the positioning posts ensure the stacking accuracy of the multiple rhomboid sheet coils. In specific implementation, the distance between the positioning posts is set according to the specifications and shape of the rhomboid sheet coils. The rough rolling device includes a material conveyor belt and a rolling cylinder located above the material conveyor belt. The fine rolling device includes a rolling mold. The process for "stacking and rolling multiple hollow cup motor rhomboid sheet coils" includes: sheet coil stacking, rough rolling, and fine rolling. The stacking process for multiple rhomboid sheet coils is as follows: The first rhomboid sheet coil is manually pulled apart from left to right and then placed on the first and third positioning posts. After releasing the hand, the first rhomboid sheet coil retracts from both sides under the elastic force, with its inner sides perfectly aligned with the first and third positioning posts, completing the placement of the first rhomboid sheet coil. The second rhomboid sheet coil is then manually pulled apart from left to right and placed on the second and fourth positioning posts. After releasing the hand, the second rhomboid sheet coil retracts from both sides under the elastic force, with its inner sides perfectly aligned with the second and fourth positioning posts, completing the placement of the second rhomboid sheet coil. This process is repeated until all rhomboid sheet coils are stacked. After stacking, the stacked rhomboid sheet coils are fixed into a single unit using adhesive or heat pressing. The rough rolling process is as follows: using a rough rolling machine, the sheet-like stacked coil, which forms a whole, is wound into an open ring. Specifically, the sheet-like stacked coil is manually guided into the rolling cylinder, and under the rolling pressure of the rolling cylinder, rough rolling is achieved. The fine rolling process is as follows: using a fine rolling machine, the coil is rolled into a closed, complete circle, completing the entire rolling process.

[0005] Existing methods for stacking and rolling rhomboid sheet coils have the following drawbacks: First, manually pulling apart the rhomboid sheet coils and placing them on the positioning posts is time-consuming, labor-intensive, and physically demanding due to the inherent rigidity of the coils. Second, coarse rolling cannot form a complete circle; fine rolling equipment is required to complete the entire rolling process. Furthermore, the manual feeding of the stacked sheet coils into the rolling cylinder during coarse rolling cannot guarantee the accuracy of the coil's feeding direction. If the stacked sheet coils are fed at an angle, the resulting coarse rolled coil will inevitably be spiral-shaped, severely impacting the quality of the finished product. Third, fine rolling equipment is required to complete the rolling process, resulting in a large number of devices and a long process flow.

[0006] Because the existing rhomboid sheet coil rolling schemes have significant shortcomings in each process, it is necessary to develop a completely new rhomboid sheet coil rolling scheme. In the development of the new rhomboid sheet coil rolling scheme, a device is needed that can position multiple arc-shaped rhomboid sheet coils at predetermined positions without affecting the inward rolling of the multiple arc-shaped rhomboid sheet coils into a single rolled coil (it is worth noting that this paragraph is only used to illustrate the research and development background of this utility model and should not be construed as prior art).

[0024] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0025] The following is in conjunction with the appendix Figure 1-9 The following is a further description of the annular movable snap-fit ​​station-type arc-shaped sheet-like rhomboid coil positioning and ejector device 1 of this utility model.

[0026] Please refer to this carefully. Figure 1-5 This utility model discloses a ring-shaped movable snap-fit ​​arc-shaped rhomboid coil positioning and top-feeding device 1, including a central cylinder 11 and a fixed support plate 12 and a movable lifting plate 13 respectively arranged around the central cylinder 11; the fixed support plate 12 includes a fixed plate body 121 and n fixed snap pins 122 fixed to the upper part of the fixed plate body 121, where n is a natural number ≥ 3; the movable lifting plate 13 includes a movable plate body 131 and n movable snap pins 132 fixed to the upper part of the movable plate body 131; the movable plate body 131 is located below the fixed plate body 121; the n fixed snap pins 122 are evenly arranged around the central cylinder 11, and the n movable snap pins 132 are evenly arranged around the central cylinder 11, and the movable snap pins 132 are located on the side of the fixed snap pins 122 closer to the central cylinder 11, and each fixed snap pin 122 has a corresponding movable snap pin 132 on one side; the movable lifting plate 13 includes a rising state and a falling state; when the movable lifting plate 13 is in the rising state (see reference... Figure 1 or Figure 2 or Figure 4 The movable locking post 132 penetrates the fixed plate body 121, and each movable locking post 132 and a fixed locking post 122 located on one side together form a coil locking slot 14; when the movable lifting plate 13 is in the lowered state (see... Figure 5 The top of the movable locking post 132 is lower than the upper surface of the fixed plate body 121, and a coil winding channel 19 is formed between the fixed locking post 122 and the central cylinder 11.

[0027] It should be noted that the annular movable snap-fit ​​station-type arc-shaped sheet-like rhombic coil positioning and ejector device 1 of this utility model is used in a brand-new rhombic sheet-like coil rolling scheme, which is different from the traditional rhombic sheet-like coil rolling scheme. The traditional rhombic sheet-like coil rolling scheme is: stacking planar rhombic coils sequentially along a straight line and then rolling them into a circle.

[0028] This new rolling solution includes: Step 1: Pre-bend the planar rhomboid sheet coil into an arc-shaped rhomboid sheet coil 100.

[0029] Step 2: Arrange the arc-shaped rhomboid coils 100 in a circular array along the same cylinder (in this embodiment, the central cylinder 11).

[0030] Step 3: Roll up all the arc-shaped rhomboid coils 100 and fold them around the central cylinder 11 to form a whole coil.

[0031] Step 4: The coiled wire wrapped around the central cylinder 11 is lifted upwards a certain distance to provide conditions for removing the coiled wire from the central cylinder 11.

[0032] The annular movable snap-fit ​​station-type arc-shaped sheet rhombus coil positioning and feeding device 1 of this embodiment is mainly used to realize the above steps S2 and S4, positioning each arc-shaped sheet rhombus coil 100 so that the arc-shaped sheet rhombus coils 100 are arranged in an annular array along the same center. Moreover, this utility model can ensure that when all the arc-shaped sheet rhombus coils 100 are wound and overlapped on the central cylinder 11, it does not affect the inward winding of the coil.

[0033] In this embodiment, the functions of each component are described as follows.

[0034] All the arc-shaped, sheet-like rhomboid coils 100 are finally wound and stacked on the central cylinder 11, the outer diameter of the central cylinder 11 being equal to the inner diameter of the wound coils.

[0035] The fixed support plate 12 is a fixed structure with multiple fixed pins 122. The number of fixed pins 122 can be set as needed. For example, if 13 arc-shaped rhomboid coils 100 are needed to form a coil, then n=13.

[0036] The movable lifting plate 13 is a height-adjustable structure with multiple movable locking pins 132. The number of movable locking pins 132 is the same as that of the fixed locking pins 122, and their positions correspond one-to-one. The movable lifting plate 13 can be switched between an upward and downward state by the movable plate lifting power 15. The movable plate lifting power 15 is used to drive the movable lifting plate 13 to move up and down. The movable plate lifting power 15 can be a lifting cylinder, or a power structure composed of a combination of a cam and a spring 151, or a combination of a wedge and a spring 151.

[0037] When the movable lifting plate 13 is in the rising state, that is, the movable locking post 132 passes through the corresponding hole on the fixed plate body 121, the movable locking post 132 rises to the side of the fixed locking post 122. The fixed plate body 121 has n coil slots 14 distributed in a preset shape. The shapes of the fixed locking post 122 and the movable locking post 132 are set according to the curvature of the arc-shaped rhomboid coil 100 to ensure that the coil slots 14 formed by the combination of the two can just lock the arc-shaped rhomboid coil 100.

[0038] The working process of this utility model is as follows: Using manual labor or a robotic arm, n arc-shaped rhomboid coils 100 are inserted one-to-one into n coil slots 14, thus positioning the n arc-shaped rhomboid coils 100 in predetermined positions. After positioning, the movable lifting plate 13 is lowered by the lifting force 15. In this state, due to the descent of the movable locking pin 132, there is no obstruction between the fixed locking pin 122 and the central cylinder 11, forming a smooth coil winding channel 19. In this state, the n arc-shaped rhomboid coils 100 can be wound and overlapped towards the central cylinder 11 under the action of external force, ultimately overlapping on the central cylinder 11 to form a complete coil. That is, the structure of this embodiment does not affect the inward winding of the coil.

[0039] It should be noted that how to use external force to roll n arc-shaped rhomboid coils 100 toward the central cylinder 11 to form a rolled coil is not the focus of the technical solution of this utility model, so it is not specifically described, and does not affect the full disclosure of this utility model.

[0040] Compared with existing technologies, the annular movable snap-fit ​​station-type arc-shaped sheet-like rhombic coil positioning and ejecting device 1 of this utility model can position multiple arc-shaped sheet-like rhombic coils 100 in predetermined positions without affecting the inward winding of multiple arc-shaped sheet-like rhombic coils 100 into a single integral coil. The annular movable snap-fit ​​station-type arc-shaped sheet-like rhombic coil positioning and ejecting device 1 of this utility model provides concrete structural support for the implementation of a novel coiling solution.

[0041] According to a specific embodiment of this utility model, the coil winding channel 19 is generally cylindrical and the bottom surface of the coil winding channel 19 is flat; the movable disc body 131 is generally circular and the movable lifting disc 13 also includes a material ejection ring 133 fixed to the upper inner side of the movable disc body 131 and surrounding the central cylinder 11. The material ejection ring 133 is generally cylindrical and slidably connected to the central cylinder 11; when the movable lifting disc 13 is in the descending state, the top surface of the material ejection ring 133 is lower than the upper surface of the fixed disc body 121; when the movable lifting disc 13 is in the ascending state, the top surface of the material ejection ring 133 is higher than the upper surface of the fixed disc body 121.

[0042] In this embodiment, the ejector ring 133 is used to achieve ejection of the top material. In use, after all the arc-shaped, sheet-like rhomboid coils 100 are wound and stacked around the central cylinder 11 to form a single coil, the coil is positioned directly above the ejector ring 133. The movable plate lifting power 15 drives the movable lifting plate 13 upwards, and the ejector ring 133 slides upwards along the central cylinder 11, pushing the coil to a certain height, causing the upper part of the coil to detach from the central cylinder 11. This facilitates automatic unloading of the coil in the next process; for example, a robotic arm can be used to grip the detached upper part of the coil to remove it. Furthermore, since the movable plate body 131, the movable clamping post 132, and the ejector ring 133 are a single fixed structure, when the movable plate lifting power 15 drives the movable lifting plate 13 to rise, the ejector ring 133 rises synchronously to achieve ejection, eliminating the need for additional lifting power. That is, the power that makes the movable locking post 132 rise and form the coil slot 14 with the fixed locking post 122 and the power that makes the ejection ring 133 rise synchronously to achieve ejection are the same power. Furthermore, the process of positioning the arc-shaped sheet-like rhomboid coil 100 in the coil slot 14 and the process of ejecting the rolled coil to achieve ejection are sequential processes that will not cause interference. This embodiment has a simple and ingenious structure, shares the same power, and has low cost.

[0043] According to a specific embodiment of this utility model, the annular movable snap-fit ​​station-type arc-shaped sheet-like rhombic coil positioning and top-feeding device 1 further includes a movable plate lifting power 15 for driving the movable lifting plate 13 to switch between a rising state and a falling state; the movable plate lifting power 15 includes: a spring 151, a guide plate 152, and a lateral telescopic power unit 153; the lateral telescopic power unit 153 includes a wedge block 1531 and a lateral telescopic drive 1532; the spring 151 is disposed between the fixed plate body 121 and the movable plate body 131; the guide plate... 152 is fixed to the lower part of the fixed disk body 121. The lower outer side of the guide disk 152 is the driven driving surface 1521, which is a cone shape with a smaller bottom and a larger top. The wedge block 1531 has an active driving surface 15311 on its upper part that abuts against the driven driving surface 1521. The active driving surface 15311 is an inclined surface that matches the driven driving surface 1521. The lateral telescopic drive 1532 is installed laterally on one side of the guide disk 152 and is connected to the wedge block 1531 for driving the wedge block 1531 to extend and retract.

[0044] This embodiment provides a specific structure for the movable lifting plate power unit 15. The guide plate 152 and the wedge block 1531 form a wedge-shaped force transmission structure, converting the horizontal extension power of the lateral telescopic power unit 153 into the vertical upward power of the guide plate 152. Driven by the guide plate 152, the movable lifting plate 13 is in an upward state. As the guide plate 152 rises, it compresses the spring 151, causing the spring 151 to accumulate elastic force. When the lateral telescopic power unit 153 retracts, under the action of the elastic force of the spring 151, the guide plate 152 lowers the movable lifting plate 13, causing the movable lifting plate 13 to be in a downward state.

[0045] In this embodiment, the lateral telescopic power unit 153 is located on the side of the guide plate 152, driving the guide plate 152 to rise from the side, and the guide plate 152 can be lowered using the spring 151. With the structure of this embodiment, the power driving the guide plate 152 to rise and fall does not occupy the center position below the guide plate 152, leaving space for installing other power components in the center position below the guide plate 152.

[0046] According to a specific embodiment of the present invention, a rolling element 154 is embedded on the driven driving surface 1521 and is tactilely connected to the wedge block 1531. The active driving surface 15311 abuts against the driven driving surface 1521 through the rolling element 154. The number of lateral telescopic power units 153 is m sets, where m is 2 or 3. The m sets of lateral telescopic power units 153 are evenly distributed on the outside of the guide plate 152.

[0047] In this embodiment, the rolling element 154 is provided to improve the smoothness of propulsion. The use of multiple evenly distributed lateral telescopic power units 153 can ensure the stability and uniformity of force distribution, which is conducive to further ensuring the reliability and smoothness of the operation.

[0048] In practical implementation, the bullseye bearing can be embedded in the wedge block 1531, with its protruding rolling ball serving as the rolling element 154. Bullseye bearings can be purchased directly, making them readily available and inexpensive.

[0049] According to a specific embodiment of this utility model, the annular movable snap-fit ​​station-type arc-shaped sheet-like rhomboid coil positioning and top material device 1 further includes a support frame 16. The support frame 16 includes a support base 161 and multiple support vertical frames 162 fixed to the upper outer side of the support base 161. The top of each support vertical frame 162 is fixedly connected to the lower part of the fixed plate body 121. The upper part of the support base 161 is provided with a recessed central column insertion groove 1611. The lower section of the central cylinder 11 passes through the guide plate 152 and is slidably connected to the guide plate 152. The bottom of the central cylinder 11 is inserted into the central column insertion groove 1611. The output end of the lateral telescopic drive 1532 is positioned directly between two adjacent support vertical frames 162.

[0050] In this embodiment, the support frame 162 provides a stable fixed support for the fixed disk body 121. The bottom of the central cylinder 11 is inserted into the groove, which facilitates the vertical positioning of the central cylinder 11. The lateral telescopic drive 1532 is staggered from the support frame 162 to avoid interference.

[0051] According to a specific embodiment of this utility model, the outer side of the bottom of the central cylinder 11 is provided with a recessed clamping ring groove 111, the support base 161 is generally in the shape of an annular disc, the support base 161 is provided with a locking component mounting hole 1612 that connects the outer side and the inner side of the support base 161, and the locking component mounting hole 1612 also connects to the clamping ring groove 111; the annular movable snap-fit ​​station type arc-shaped plate-shaped rhomboid coil positioning and top material device 1 also includes a locking screw 17, one end of the locking screw 17 is fixed in the locking component mounting hole 1612, and the other end of the locking screw 17 abuts against the bottom of the clamping ring groove 111.

[0052] In this embodiment, the locking screw 17 is inserted through the locking component mounting hole 1612 to lock and fix the support base 161 and the central cylinder 11, ensuring that the lower part of the central cylinder 11 is fixed in the central cylinder insertion groove 1611.

[0053] According to a specific embodiment of this utility model, a protruding limiting ring 1522 is also provided on the outer side of the guide plate 152, and the lower part of the limiting ring 1522 is a descending limiting plane 15221; the annular movable snap-fit ​​station-type arc-shaped sheet-like rhomboid coil positioning and top material device 1 also includes an adjusting screw 18, the lower part of the adjusting screw 18 is threadedly connected to the supporting base 161, and the upper part of the adjusting screw 18 is set directly opposite the descending limiting plane 15221.

[0054] In this embodiment, adjusting the position between the top of the adjusting screw 18 and the lowering limit plane 15221 can control the lowering stroke of the guide plate 152 under the action of spring force, thereby achieving precise control of the lowering stroke.

[0055] According to a specific embodiment of this utility model, the top surface of the movable locking post 132 is a plane, and the top surface of the ejector ring 133 and the top surface of the movable locking post 132 are located in the same horizontal plane.

[0056] In this embodiment, the top surfaces of the movable locking post 132 and the ejector ring 133 are located in the same horizontal plane, which means that the movable locking post 132 and the ejector ring 133 have the same height.

[0057] Compared to a structure where the movable locking post 132 and the ejector ring 133 are at unequal heights, in this design, the movable locking post 132 and the ejector ring 133 descend synchronously below the upper surface of the fixed disc body 121 to form a flat coil winding channel 19. The top surfaces of the movable locking post 132 and the ejector ring 133 rise synchronously to form the coil slot 14 or to eject material, without any wasted travel. This structure ensures minimal lifting travel while meeting functional requirements, thus reducing the overall size of the device.

[0058] Please refer to this carefully. Figure 6-7 as well as Figure 9 According to a specific embodiment of this utility model, each coil slot 14 is used to clamp and fix an arc-shaped sheet rhombus coil 100. The arc-shaped sheet rhombus coil 100 is generally arc-shaped, with the radius of the arc of the outer wall of the arc-shaped sheet rhombus coil 100 being R1 and the radius of the arc of the inner wall of the arc-shaped sheet rhombus coil 100 being R2. The side of the fixed locking post 122 near the central cylinder 11 is an arc surface that matches the curvature of the outer wall of the arc-shaped sheet rhombus coil 100, and the side of the movable locking post 132 away from the central cylinder 11 is an arc surface that matches the curvature of the inner wall of the arc-shaped sheet rhombus coil 100.

[0059] In this embodiment, the two opposing surfaces of the fixed locking post 122 and the movable locking post 132 are arc surfaces that match the inner and outer surfaces of the arc-shaped rhomboid coil 100. This structure is beneficial for clamping and fixing the arc-shaped rhomboid coil 100.

[0060] It should be noted that in this embodiment, "matching" means that the radius of the arc surface is basically the same as that of the matched object, that is, the radius of the arc surface needs to be slightly larger or slightly smaller than that of the matched object. For example, the arc radius of the side of the fixed pin 122 near the central cylinder 11 is R1+0.5~R1+1mm; or the arc radius of the side of the movable pin 132 away from the central cylinder 11 is R2-0.5~R2-1mm. In specific implementation, it is necessary to select according to the actual thickness of the arc-shaped rhomboid coil 100 to ensure that the arc-shaped rhomboid coil 100 can be flexibly inserted and firmly locked in the coil slot 14.

[0061] Please refer to this carefully. Figure 6-8According to a specific embodiment of this utility model, the lower part of the arc-shaped sheet rhomboid coil 100 includes a proximal segment 101, a middle segment 102, and a distal segment 103 connected in sequence; the arc-shaped sheet rhomboid coil 100 includes a snap-fit ​​state; when the arc-shaped sheet rhomboid coil 100 is in the snap-fit ​​state: two adjacent arc-shaped sheet rhomboid coils 100 are spaced apart, and the inner sidewall of the arc-shaped sheet rhomboid coil 100 faces the central cylinder 11, and the end of the proximal segment 101 away from the middle segment 102 abuts against the outer side of the central cylinder 11, and the end of the distal segment 103 away from the middle segment 102 is spaced apart from the outer side of the central cylinder 11, and the middle segment 102 is snapped into the coil slot 14.

[0062] In this embodiment, the proximal segment 101 refers to the portion of the arc-shaped rhomboid coil 100 near the central cylinder 11, the middle segment 102 refers to the middle section of the arc-shaped rhomboid coil 100, and the distal segment 103 refers to the portion of the arc-shaped rhomboid coil 100 away from the central cylinder 11. This embodiment specifically discloses the shape of the arc-shaped rhomboid coil 100 itself, and its position when it is in a snap-fit ​​state.

[0063] In this invention, the coil slots 14 are arranged in a circular array around the central cylinder 11 to position the arc-shaped, sheet-like rhomboid coil 100 according to a preset position. Each coil slot 14 in this invention serves as a clamping station for an arc-shaped, sheet-like rhomboid coil 100. The clamping station is a movable structure, providing conditions for the ejection of the wound coil in this invention.

[0064] It should be noted that this utility model is used to realize that multiple arc-shaped sheet-like rhomboid coils 100 are fixedly distributed outside the central cylinder 11 at a preset position, that is, each arc-shaped sheet-like rhomboid coil 100 is fixed at a preset position, which facilitates the next process (coil winding process). The coil winding process is specifically as follows: the component is inserted into both sides inside each arc-shaped sheet-like rhomboid coil 100, and all arc-shaped sheet-like rhomboid coils 100 are pulled apart and wound onto the central cylinder 11 to form an integral rolled coil.

[0065] It should be noted that how to pull open the arc-shaped rhomboid coil 100 and wrap it around the central cylinder 11 to form an integral rolled coil is not a technical problem that this utility model needs to solve. This utility model does not specifically disclose its implementation structure, which does not affect the full disclosure of this utility model.

[0066] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components; and they can also refer to a "transmission connection," that is, a power connection through various suitable methods such as belt drive, gear drive, or sprocket drive. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
