[0002] In the production of hollow cup motor coils, the main processes include winding, flattening, coiling, wire trimming, and tinning. After the enameled wire is wound on the winding die to form a hollow coil with multiple wire ends, a flattening device flattens the hollow coil into a flat shape. Following the flattening process, a pressing and shaping process may also occur, ultimately resulting in a sheet-like hollow cup coil including the wire ends. During the flattening and pressing and shaping processes, the shape and position of the wire ends in the sheet-like hollow cup coil may change.

[0003] In existing hollow cup motor coil production equipment, there is no device for straightening the wire ends of the flattened sheet-shaped hollow cup coil.

[0004] The shortcoming of the existing technology is that if the shape and position of the wire ends of the sheet-shaped hollow cup coil change and are not corrected in time, it will be detrimental to the processing of subsequent processes. For example, if the position of the wire ends is not accurate in the subsequent processes of tinning, wire end trimming and resistance testing, it will affect the product accuracy and make it difficult to accurately position each wire end, which increases the difficulty of automating the process.

[0005] Therefore, it is necessary to provide a new device for straightening the end of a sheet-shaped hollow cup coil and for flattening and rounding it for transfer to solve the above-mentioned technical problems. Summary of the Invention

[0038] 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.

[0039] The following is in conjunction with the appendix Figure 1-6 The present invention provides a further description of the end 01 for straightening the coil wire end of the sheet-shaped hollow cup and the flattening and rounding transfer device 100.

[0040] Please refer to this carefully. Figure 1-4 This utility model discloses a straightening actuator 01 for sheet-shaped hollow cup coil ends, including a two-finger opening and closing gripper 1 and two sets of straightening actuators 2 respectively connected to the two-finger opening and closing gripper 1. The straightening actuator 2 includes: a straightening gripper 21, a straightening quick-change gripper 22, and a tooth gap adjustment telescopic drive 23; the lower part of the straightening gripper 21 is provided with a recessed mounting groove 211, and the length and width directions of the mounting groove 211 are respectively in the X direction and the Y direction; the two sets of straightening actuators 2 are arranged opposite each other along the X direction. The two-finger opening and closing gripper 1 is used to drive the two sets of cable straightening actuators 2 to open and close in the X direction; the upper part of the cable straightening quick-change gripper 22 extends into the mounting groove 211, the tooth gap adjustment telescopic drive 23 is installed on one side of the cable straightening gripper 21, the tooth gap adjustment telescopic drive 23 is connected to the cable straightening quick-change gripper 22, and is used to drive the cable straightening quick-change gripper 22 to move in the Y direction, and the lower part of the two cable straightening quick-change grippers 22 in the two sets of cable straightening actuators 2 is respectively fixedly connected with the first cable straightening quick-change comb tooth 3 and the second cable straightening quick-change comb tooth 4.

[0041] The sheet-shaped hollow cup coil 200 includes a coil body 202 that is generally sheet-shaped and a wire end 201 located at the top of the coil body 202. When the wire end 201 is not in the correct position due to processes such as flattening or shaping, the wire end 01 of the sheet-shaped hollow cup coil of this utility model can be used to straighten the wire end 201 before proceeding to the next process.

[0042] The components and functions in this embodiment are described in detail below.

[0043] The two-finger opening and closing gripper 1 drives the two sets of wire straightening actuators 2 to open and close, and the first wire straightening quick-change comb 3 and the second wire straightening quick-change comb 4 open and close synchronously. Both the first wire straightening quick-change comb 3 and the second wire straightening quick-change comb 4 have toothed structures, and they can move closer to each other or further away from each other under the action of the two tooth gap adjustment extension drive 23. Moreover, the gap of the toothed structure is set according to the gap between the root of the wire end 201 on the sheet hollow cup coil 200 to ensure that the first wire straightening quick-change comb 3 and the second wire straightening quick-change comb 4 can cooperate to straighten the wire end 201 directly upwards.

[0044] The following describes in detail the process of straightening the end of the sheet-shaped hollow cup coil of this utility model at the execution end 01.

[0045] The flattening or pressing shaping device clamps the coil body 202 with the wire end 201 facing upwards. The straightening execution end 01 of the sheet-shaped hollow cup coil of this utility model is transferred to the top of the wire end 201. The two-finger opening and closing gripper 1 drives the first wire-straightening quick-change comb tooth 3 and the second wire-straightening quick-change comb tooth 4 to open in the X direction, aligning the wire end 201 and moving it downwards, while ensuring that each wire end 201 is located in the gap between the teeth of the first wire-straightening quick-change comb tooth 3 and the second wire-straightening quick-change comb tooth 4.

[0046] Under the action of the two tooth gap adjustment telescopic drive 23, the first thread-straightening quick-change comb tooth 3 and the second thread-straightening quick-change comb tooth 4 approach each other, and the tooth gap becomes smaller, eventually making the tooth gap slightly larger than or equal to the maximum lateral dimension of the thread end 201; then the two-finger opening and closing gripper 1 and the two sets of thread-straightening actuators 2 move upward as a whole, and the thread end 201 is straightened under the action of the first thread-straightening quick-change comb tooth 3 and the second thread-straightening quick-change comb tooth 4.

[0047] Compared with the prior art, the end 01 of the sheet-shaped hollow cup coil straightening device of this utility model can straighten multiple deformed wire ends 201 at the same time, which can improve product accuracy. After the wire ends 201 are straightened, it is easier to accurately position the wire ends 201, reducing the difficulty of automating subsequent processes.

[0048] According to a specific embodiment of the present invention, the sheet-shaped hollow cup coil wire straightening execution end 01 also includes a wire straightening lifting drive 5 fixed to the upper part of the two-finger opening and closing gripper 1. The height direction of the mounting groove 211 is set to the Z direction, and the wire straightening lifting drive 5 is used to drive the two-finger opening and closing gripper 1 and the wire straightening execution part 2 to move up and down as a whole along the Z direction.

[0049] In this embodiment, the cable lifting drive 5 is located on the upper part of the two-finger opening and closing gripper 1, which facilitates lifting.

[0050] According to a specific embodiment of this utility model, the first winding quick-change comb tooth 3 is provided with a plurality of spaced first racks 31 on the side near the second winding quick-change comb tooth 4, and the second winding quick-change comb tooth 4 is provided with a plurality of spaced second racks 41 on the side near the first winding quick-change comb tooth 3. The first racks 31 and the second racks 41 are staggered. The two tooth gap adjustment telescopic drives 23 in the two sets of winding execution parts 2 are located on the same side of the two-finger opening and closing gripper 1.

[0051] When the two-finger opening and closing gripper 1 closes, the first rack 31 and the second rack 41 are staggered and interlocked. One first rack 31 and its connected second rack 41 together form a thread straightening space, which encloses a thread end 201. Two backlash adjustment telescopic drives 23 located on the same side extend one and retract the other, which can shorten the gap between the first rack 31 and its adjacent second rack 41 until the gap required for straightening the thread end 201 is obtained, and then stop. The two backlash adjustment telescopic drives 23 are located on the same side, which can reduce the footprint and make the structure more compact.

[0052] According to a specific embodiment of the present invention, the cable straightening execution part 2 further includes a sliding guide 6. The sliding guide 6 includes a guide sleeve 61 and a guide post 62 that slides through the guide sleeve 61. The guide sleeve 61 is embedded in the cable straightening quick-change claw 22, and the guide post 62 passes through the cable straightening claw 21. At least one end of the guide post 62 is detachably and fixedly connected to the side wall of the cable straightening claw 21.

[0053] In this embodiment, the sliding guide 6 is provided to improve the smoothness of the cable-strapping quick-change claw 22 moving in the Y direction. One end of the guide post 62 can be tightened in the side wall of the cable-strapping claw 21, or fixed by a pin, to ensure that the guide post 62 will not slide axially during use. When it needs to be removed, the guide post 62 can be knocked out in the opposite direction to ensure that the cable-strapping quick-change claw 22 can be quickly installed and changed.

[0054] According to a specific embodiment of this utility model, a set of sliding guides 6 are provided above and below the position where the tooth gap adjustment telescopic drive 23 is connected to the wire straightening quick-change gripper 22.

[0055] In this embodiment, the structure is adopted, and a set of sliding guides 6 are provided above and below the power component, which improves the guiding balance and further helps to ensure the smooth sliding of the cable-changing quick-change gripper 22.

[0056] According to a specific embodiment of the present invention, the cable straightening actuator 2 further includes two Y-direction limiting screws 7 respectively disposed on both sides of the cable straightening quick-change claw 22. One end of the Y-direction limiting screw 7 is threadedly connected to the cable straightening claw 21, and the other end extends into the mounting groove 211 to limit the movement of the cable straightening quick-change claw 22 in the Y direction. The Y-direction limiting screw 7 is located below the sliding guide 6.

[0057] It should be noted that, in specific implementation, the movement stroke of the cable-strapping quick-change gripper 22 can be controlled in conjunction with the electrical system. In this embodiment, a Y-direction limiting screw 7 is used to ensure that, in the event of electrical system failure, the cable-strapping quick-change gripper 22 slides within a predetermined stroke using mechanical limiting, thus avoiding overtravel movement and the collision of the first rack 31 and the second rack 41.

[0058] According to a specific embodiment of the present invention, the first quick-change comb tooth 3 and the quick-change clamp 22 are detachably connected by a threaded connector, the second quick-change comb tooth 4 and the quick-change clamp 22 are detachably connected by a threaded connector, and the quick-change clamp 22 and the quick-change clamp 21 are detachably connected.

[0059] It should be noted that the tooth pitch of the first winding quick-change comb 3 and the second winding quick-change comb 4 must match the spacing of the wire ends 201 of the sheet coil to be straightened. When the specifications of the hollow cup motor coil to be produced are different, the distance between the wire ends 201 may also be different, and the first winding quick-change comb 3 and the second winding quick-change comb 4 with matching tooth pitch need to be replaced accordingly.

[0060] In this embodiment, the first quick-change comb tooth 3 and the second quick-change comb tooth 4 are configured as detachable structures, which can meet the above-mentioned replacement needs and expand the scope of application of this utility model.

[0061] According to a specific embodiment of this utility model, the two-finger opening and closing gripper 1 is a two-finger pneumatic gripper, the tooth gap adjustment telescopic drive 23 is a telescopic cylinder, and the wire straightening lifting drive 5 is a telescopic cylinder.

[0062] In this embodiment, all power components are pneumatically driven, which facilitates the driving of all power sources under a single pneumatic system. Of course, the two-finger opening and closing gripper 1, the tooth gap adjustment telescopic drive 23, and the line straightening lifting drive 5 can also be electrically driven and hydraulically driven.

[0063] Please refer to this carefully. Figure 5-6 This utility model also discloses a flattening and rounding transfer device 100, including: a three-axis transfer module 04, a clamping execution end 02, a pre-pressing execution end 03, and a sheet-shaped hollow cup coil wire end straightening execution end 01 as described above. The sheet-shaped hollow cup coil wire end straightening execution end 01, the clamping execution end 02, and the pre-pressing execution end 03 are sequentially mounted side by side on the three-axis transfer module 04. The clamping execution end 02 includes: a triangular opening and closing chuck 8 and a chuck lifting drive 9 for driving the triangular opening and closing chuck 8 to move up and down in the Z direction. The pre-pressing execution end 03 includes: a pre-pressing head 10 and a pre-pressing lifting drive 11 for driving the pre-pressing head 10 to move up and down in the Z direction.

[0064] In this embodiment, the three-axis transfer module 04 can be an existing XYZ axis transfer module that can be directly purchased, or it can be composed of three unidirectional moving modules. Ultimately, under the action of the three-axis transfer module 04, it can move the clamping actuator 02, the pre-compression actuator 03, and the sheet-shaped hollow cup coil wire straightening actuator 01 loaded on it to the required position. The sheet-shaped hollow cup coil wire straightening actuator 01, the clamping actuator 02, and the pre-compression actuator 03 can extend and retract independently along the Z-axis, with only one module extending at a time.

[0065] The working process of the flattening and rounding transfer device 100 of this utility model is described in detail below:

[0066] First, the sheet-shaped hollow cup coil 200 is located at the flattening station, where the coil body 202 is clamped by the flattening device. The end 01 of the sheet-shaped hollow cup coil wire straightening device extends out and straightens the wire end 201 located at the top of the coil body 202 (refer to the above content for details). Under the action of the wire straightening lifting drive 5, the end 01 of the sheet-shaped hollow cup coil wire straightening device is retracted upward to above the three-axis transfer module 04.

[0067] Then, the chuck lifting drive 9 extends downward, driving the clamping execution end 02 to move downward to the flattening station and clamp the coil body 202. The flattening device opens, and the clamping execution end 02, under the action of the three-axis transfer module 04, moves to the rounding station, completing the transfer of the sheet-shaped hollow cup coil 200 from the flattening station to the rounding station. Under the action of the chuck lifting drive 9, it retracts upward to above the three-axis transfer module 04.

[0068] The pre-pressure lifting drive 11 extends downwards, and the pre-pressure execution end 03 extends into the rounding station. The rounding station includes a rounding bar. The middle section of the sheet-shaped hollow cup coil 200 is tangent to the outer side of the rounding bar. One end of the sheet-shaped hollow cup coil 200 is fixed, and the other end is a free end. Under the action of the triaxial transfer module 04, the clamping execution end 02 moves and squeezes the free end of the sheet-shaped hollow cup coil 200, and deforms the free end along the shape of the winding rounding bar. Using the pre-pressure execution end 03, the sheet-shaped hollow cup coil 200 can be pre-deformed before the formal rounding, ensuring the smoothness and quality of the subsequent rounding deformation. It is especially suitable for sheet-shaped hollow cup coils 200 that are thick and difficult to deform in one press.

[0069] According to a specific embodiment of the present invention, the pre-compression head 10 includes: a mounting block 101, an upper rotating shaft 102, and a detachable pre-compression rod 103; the mounting block 101 is fixedly mounted on the lower part of the pre-compression lifting drive 11, the upper part of the upper rotating shaft 102 extends into the mounting block 101, and the upper rotating shaft 102 is rotatably connected to the mounting block 101 via a bearing 104, and the upper part of the detachable pre-compression rod 103 is inserted into the upper rotating shaft 102, and the two are detachably connected.

[0070] In this embodiment, the upper rotating shaft 102 is rotatably connected to the mounting block 101 via the bearing 104, ensuring smooth rotation of the upper rotating shaft 102. The detachable preload rod 103 is detachably connected to the upper rotating shaft 102. The lower part of the detachable preload rod 103 is cylindrical. In specific implementations, detachable preload rods 103 of different diameters can be installed as needed to meet usage requirements.

[0071] In this embodiment, the detachable pre-compression rod 103 is rotatable. When pre-compressing the sheet-like hollow cup coil 200, the operating mechanism of the detachable pre-compression rod 103 is to squeeze the sheet-like hollow cup coil 200 while rotating itself. This avoids wear on the surface of the sheet-like hollow cup coil 200, further ensuring product quality.

[0072] The flattening and rounding transfer device 100 of this utility model integrates the functions of straightening, clamping and pre-pressing. Compared with conventional coil production devices, it adds the functions of straightening the head 201 after flattening and pre-pressing deformation before rounding, which greatly improves the forming accuracy of the product. The flattening and rounding transfer device 100 also realizes the transfer of the sheet-shaped hollow cup coil 200 from the flattening station to the rounding station by clamping the execution end 02. The three execution ends share a set of three-axis transfer module 04, which has a compact and reasonable structure and is also conducive to reducing costs.

[0073] 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.
