Description

Technical Field

[0001] This utility model belongs to the field of hollow cup motor coil production technology, and particularly relates to a coil flattening device for a hollow cup motor coil production line. Background Technology

[0002] In the production process of coreless motors, coil fabrication is a crucial step, encompassing multiple processes such as winding, flattening, wire end removal, and tinning. Among these, the flattening process plays a decisive role in the final performance and quality of the motor. After the enameled wire is wound on the winding die to form a hollow coil with multiple wire ends, it must be flattened into a flat shape before proceeding to subsequent processes such as wire end removal and tinning.

[0003] In the prior art, Chinese patent CN203708033U discloses a coil flattening mechanism in the manufacturing process of motor coils. This mechanism includes a clamping component for gripping a hollow coil, a flattening component for flattening the hollow coil, and a moving component that drives the clamping component to a winding die. The flattening component includes a misalignment mechanism that allows a first flattening plate to move offset relative to a second flattening plate to flatten the hollow coil. The misalignment mechanism includes a first actuating block, a second actuating block, and a driving assembly for driving the second actuating block to rotate so that the first flattening plate moves offset relative to the second flattening plate. The second actuating block is rotatably connected to the driving assembly. The driving assembly includes a gear disposed below the second actuating block, a rack meshing with the gear, and a cylinder for driving the rack to move.

[0004] The flattening process is as follows: the first and second cutting plates clamp the two opposite outer sides of the wound hollow coil, respectively. The cylinder pushes the rack to move, which drives the gear meshing with it to rotate. The second actuating block connected to the gear rotates accordingly. Since the first actuating block is engaged with the second actuating block, the first actuating block also rotates with the gear. The first and second cutting plates are connected to the first actuating block, thereby realizing the offset movement of the first cutting plate relative to the second cutting plate (the first and second cutting plates move back and forth while moving closer to each other), so as to flatten the wound hollow coil located between the first and second cutting plates into a flat shape.

[0005] The existing coil flattening mechanism has the following two shortcomings in practical use:

[0006] First, when using existing drive components to drive the first and second washboards, their movement paths are entirely controlled by the drive components. In practice, due to the relatively long length of the first and second washboards and the lack of effective guiding structures in the vertical direction, as well as the fact that the cylinder and rack, which provide direct power, are located on one side of the gears, the movement accuracy and smoothness of the first and second washboards are low. Ultimately, this results in uneven force distribution or even force misalignment when flattening hollow coils, making it difficult to ensure the stability of the flattening effect and leading to a high scrap rate.

[0007] Secondly, during the flattening process of the hollow coil, there is a lack of effective positioning measures for the coil bundle and the wire ends. Under pressure, the position of the coil bundle and wire ends is very prone to slippage and misalignment. Once slippage occurs, the position of the coil bundle and wires after flattening will deviate from the predetermined position and shape, thus making the product defective.

[0008] Due to the significant defects mentioned above in the existing technology of flattening hollow cup motor coils, it is difficult to ensure the stability of the flattening effect when using the above-mentioned coil flattening mechanism to flatten hollow coils, resulting in a high scrap rate.

[0009] Therefore, it is necessary to provide a new coil flattening device for a hollow cup motor coil production line to solve the above-mentioned technical problems. Summary of the Invention

[0051] 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.

[0052] The following is in conjunction with the appendix Figure 1-11 The coil flattening device for a hollow cup motor coil production line of this utility model will be further described.

[0053] Please refer to this carefully. Figure 1-6This utility model provides a coil flattening device for a hollow cup motor coil production line, used to flatten a wound hollow coil 100 to obtain a flat, regular wire block 200. The wound hollow coil 100 includes a first sidewall 101 and a second sidewall 102 arranged opposite to each other. The coil flattening device for the hollow cup motor coil production line includes an anti-misalignment coil flattening execution module 01 and an anti-jamming coil flattening power module 02. The anti-misalignment coil flattening execution module 01 includes a first wire twisting assembly 11 and a second wire twisting assembly 12 arranged opposite to each other. The first wire twisting assembly 11 includes a first twisting plate 111 and a first inner pressure plate 112. The second wire twisting assembly 12 includes a second twisting plate 121 and a second inner pressure plate 122. The first twisting plate 111 and the second twisting plate 121 are arranged opposite to each other. The first inner pressure plate 112 is installed on the first twisting plate 111 and moves synchronously with the first twisting plate 111. The first inner pressure plate 112 can also independently realize extension and retraction and opening and closing movements. The inner pressure plate 122 is mounted on the second rubbing plate 121 and moves synchronously with the second rubbing plate 121. The second inner pressure plate 122 can also independently achieve telescopic and opening / closing movements. The first inner pressure plate 112 and the first rubbing plate 111 are used to clamp the inner and outer sides of the first sidewall 101, respectively. The second inner pressure plate 122 and the second rubbing plate 121 are used to clamp the inner and outer sides of the second sidewall 102, respectively. The anti-jamming coil flattening power module 02 includes an active linkage rubbing disc 21 and a rotary drive 22. The upper sides of the active linkage rubbing disc 21 are rotatably connected to the first rubbing plate 111 and the second rubbing plate 121 respectively. The rotation drive 22 is connected to the active linkage rubbing disc 21 and the two are coaxial. It is used to drive the active linkage rubbing disc 21 to rotate so as to drive the first rubbing plate 111 and the second rubbing plate 121 to achieve misalignment. The hollow coil winding 100 also includes multiple wire ends distributed in a straight line. The anti-misalignment coil flattening execution module 01 also includes a wire clamping head assembly 13 for simultaneously clamping and fixing all wire ends.

[0054] This invention is used to implement a flattening process. The preceding process for flattening is coil winding. After completing the coil winding process, a hollow coil 100 is placed on a hexagonal winding mold (not shown in the figure). The hollow coil 100 is hexagonal in shape, matching the open shape of the hexagonal winding mold. This invention requires removing the hollow coil 100 from the hexagonal winding mold and flattening it. When removing the hollow coil 100, the hexagonal winding mold can retract, facilitating the flexible removal of the hollow coil 100. During operation, under the action of the transfer mechanism, the entire invention approaches the hexagonal winding mold. The extended ends of the first and second rubbing plates 111 and 121 respectively hold the outer sides of the two opposite sides (first sidewall 101 and second sidewall 102) of the hollow coil 100. Under the action of the transfer mechanism, the entire invention moves away from the hexagonal winding mold to remove the hollow coil 100.

[0055] After the hollow coil 100 is removed, the first inner pressure plate 112 and the second inner pressure plate 122 extend into the hollow coil 100. The first inner pressure plate 112 cooperates with the protruding end of the first tumbling plate 111 to clamp the inner and outer sides of the first sidewall 101, thereby fixing the position of the wire bundle in the first sidewall 101. The second inner pressure plate 122 cooperates with the protruding end of the second tumbling plate 121 to clamp the inner and outer sides of the second sidewall 102, thereby fixing the position of the wire bundle in the second sidewall 102. Based on this, the opening and closing wire end clamping assembly 13 is used to clamp and fix all wire ends throughout the flattening process.

[0056] Then, the rotary drive 22 rotates, driving the active linkage rubbing disc 21 to rotate. Since the upper two sides of the active linkage rubbing disc 21 are respectively rotatably connected to the first rubbing plate 111 and the second rubbing plate 121, the first rubbing plate 111 and the second rubbing plate 121 are finally moved in a staggered manner (moving closer to each other while moving alternately) until the first inner pressure plate 112 and the second inner pressure plate 122 are about to touch, thus stopping the staggered movement and realizing the main flattening process of winding the hollow coil 100 (the entire flattening process consists of the main flattening process and the supplementary flattening process). Then, the first inner pressure plate 112 and the second inner pressure plate 122 are pulled out from the winding hollow coil 100 and spread outward, providing space for the continued staggered movement of the first rubbing plate 111 and the second rubbing plate 121. The continued staggered movement of the first rubbing plate 111 and the second rubbing plate 121 realizes the supplementary flattening process of winding the hollow coil 100, resulting in a flat, regular wire block 200.

[0057] Compared with the prior art, the present invention has the following beneficial effects:

[0058] In terms of driving power, the existing linear drive power structure (cylinder-driven rack 26 structure) has been abandoned, and a structure in which the rotary drive 22 first drives the active linkage rubbing disc 21 to rotate is adopted, which changes the force transmission mechanism. Since the rotary drive 22 and the active linkage rubbing disc 21 are coaxial, in practical applications, the active linkage rubbing disc 21 can be subjected to the coaxial driving force provided by the rotary drive 22, ensuring the smooth rotation of the active linkage rubbing disc 21. This avoids the first rubbing disc 111 and the second rubbing disc 121 being subjected to tilting forces from the power source, which is conducive to ensuring the accuracy of the operation of the first rubbing disc 111 and the second rubbing disc 121. Finally, under the joint action of the first rubbing disc 111 and the second rubbing disc 121, the hollow coil 100 is subjected to a uniform rubbing force that moves in a predetermined direction, effectively avoiding the phenomenon of wire harness misalignment during the flattening process of the hollow coil 100, greatly improving the stability of the flattening and forming effect, and resulting in a high yield.

[0059] Regarding the flattening actuators, a first inner pressure plate 112 and a second inner pressure plate 122 have been added. This ensures that the first sidewall 101 and the second sidewall 102 remain fixed throughout the main flattening process. Since the main flattening process completes most of the deformation actions, effectively preventing slippage or misalignment of the wire harness during the flattening process of the hollow coil 100 under stress, the stability of the flattening effect is improved, ensuring that the resulting regular wire block 200 matches the predetermined shape and significantly increasing the yield of the regular wire block 200. Furthermore, the added opening and closing wire end clamp assembly 13 effectively prevents slippage or misalignment of the wire end during the flattening process of the hollow coil 100 under stress, further enhancing the stability of the flattening effect.

[0060] According to a specific embodiment of the present invention, the first swivel plate 111 includes: a first front and rear swivel plate 1111 and a first outer pressure plate 1112 fixedly installed at one end of the first front and rear swivel plate 1111; the second swivel plate 121 includes: a second front and rear swivel plate 1211 and a second outer pressure plate 1212 fixedly installed at one end of the second front and rear swivel plate 1211; the first inner pressure plate 112 and the first outer pressure plate 1112 are respectively used to press and clamp the inner and outer sides of the first sidewall 101; the second inner pressure plate 122 and the second outer pressure plate 1212 are respectively used to press and clamp the inner and outer sides of the second sidewall 102; the upper two sides of the active linkage swivel disc 21 are rotatably connected to the first front and rear swivel plate 1111 and the second front and rear swivel plate 1211 respectively; the first swivel assembly 11 also includes a mechanism for individually extending, retracting, opening, and closing the first inner pressure plate 112. The first inner pressure plate cross linear drive 113 is used for movement. The second thread twisting assembly 12 also includes a second inner pressure plate cross linear drive 123 for realizing the individual extension and retraction and opening and closing movement of the second inner pressure plate 122. The first inner pressure plate 112 is installed on the first front and rear thread twisting plates 1111 via the first inner pressure plate cross linear drive 113, and the second inner pressure plate 122 is installed on the second front and rear thread twisting plates 1211 via the second inner pressure plate cross linear drive 123. The anti-jamming coil flattening power module 02 also includes a rack 26 and a driven linkage twisting disc 23. The driving linkage twisting disc 21 is fixedly connected to the driving gear 24, and the driven linkage twisting disc 23 is fixedly connected to the driven gear 25. The rack 26 meshes with the driving gear 24 and the driven gear 25 respectively. The rotary drive 22 is located below the driving gear 24 and connected to the driving gear 24.

[0061] More specifically, the upper sides of the driven linkage rubbing disc 23 slide and abut against the inner walls of the first front and rear rubbing plates 1111 and the second front and rear rubbing plates 1211, respectively.

[0062] like Figure 5In this embodiment, the first inner pressure plate cross linear drive 113 and the second inner pressure plate cross linear drive 123 can extend and retract along the X-axis (the length direction of the first washboard 111) and the Y-axis (the width direction of the first washboard 111), respectively. The first inner pressure plate cross linear drive 113 and the second inner pressure plate cross linear drive 123 can be existing cross linear drive modules that can be directly purchased, or they can be composed of two linear drive modules combined. Since the first inner pressure plate 112 is mounted on the first washboard 111, when the first inner pressure plate cross linear drive 113 is stationary, the first inner pressure plate 112 moves synchronously with the first washboard 111; similarly, since the second inner pressure plate 122 is mounted on the second washboard 121, when the second inner pressure plate cross linear drive 123 is stationary, the second inner pressure plate 122 moves synchronously with the second washboard 121.

[0063] More specifically, the first front and rear winding plates 1111 are horizontal plates. The first outer pressure plate 1112 is a long, thin rod, and the two are detachably connected. In specific implementations, the first outer pressure plate 1112 of different regular sizes can be replaced according to the specifications and dimensions of the hollow coil 100 being wound. The horizontal plate shape of the first front and rear winding plates 1111 facilitates providing sufficient and stable installation space for the active linkage winding disc 21 and the first inner pressure plate cross-shaped linear drive 113. The structure and function of the second winding plate 121 are described above for the first winding plate 111, and will not be repeated here.

[0064] In use, the rotary drive 22 rotates, causing the drive gear 24 and the drive linkage spinning plate 21 to rotate as a whole. Since the rack 26 meshes with the drive gear 24 and the driven gear 25 respectively, the driven gear 25 and the driven linkage spinning plate 23 rotate as a whole. Ultimately, the first front and rear spinning plates 1111 and the second front and rear spinning plates 1211 are moved in a staggered manner.

[0065] Please refer to this carefully. Figure 9-10 According to a specific embodiment of the present invention, the first wire twisting assembly 11 and the second wire twisting assembly 12 are symmetrical to each other; the first front and rear wire twisting plate 1111 is provided with a recessed first inner pressure plate receiving groove 11111 on the side near the second front and rear wire twisting plate 1211, and the second front and rear wire twisting plate 1211 is provided with a recessed second inner pressure plate receiving groove 12111 on the side near the first front and rear wire twisting plate 1111. The anti-misalignment coil flattening execution module 01 includes a fully retracted state. When the anti-misalignment coil flattening execution module 01 is in the fully retracted state, the first inner pressure plate 112 is received in the first inner pressure plate receiving groove 11111, and the second inner pressure plate 122 is received in the second inner pressure plate receiving groove 12111. The gap between the first outer pressure plate 1112 and the second outer pressure plate 1212 is less than or equal to the thickness of the regular wire block 200.

[0066] In this embodiment, before the supplementary flattening process of the wound hollow coil 100, the first inner pressure plate cross linear drive 113 drives the first inner pressure plate 112 to retract into the first inner pressure plate receiving groove 11111, and at the same time, the second inner pressure plate cross linear drive 123 drives the second inner pressure plate 122 to retract into the second inner pressure plate receiving groove 12111. This reduces the size of the device and facilitates the continued closing of the first outer pressure plate 1112 and the second outer pressure plate 1212 to complete the supplementary flattening process. In the fully retracted state, the gap between the first outer pressure plate 1112 and the second outer pressure plate 1212 ensures that the wound hollow coil 100 is completely flattened. In this embodiment, since the first wire twisting assembly 11 and the second wire twisting assembly 12 are symmetrical structures, the specific structure of the second wire twisting assembly 12 is the same as that of the first wire twisting assembly 11.

[0067] Please refer to Figure 9 The diagram, from top to bottom, shows the first inner pressure plate 112 in three states: open / retracted, open / extended, and pressing against the coil sidewall. Please refer to... Figure 10 The diagram shows, from top to bottom, the second inner pressure plate 122 in the state of being housed in the second inner pressure plate receiving groove 12111 and in the open and extended state.

[0068] According to a specific embodiment of this utility model, the first inner pressure plate cross linear drive 113 includes: a wide-direction slide rail module 1131, a wide-direction connecting plate 1132, a wide-direction telescopic power 1133, a long-direction slide rail module 1134, a long-direction connecting plate 1135, and a long-direction telescopic power 1136; the wide-direction slide rail module 1131 includes: a wide-direction guide rail and a wide-direction guide groove body that cooperates with the wide-direction guide rail. The wide-direction guide rail and the wide-direction telescopic power 1133 are respectively fixed to the upper part of the first front and rear thread-rolling plates 1111 along the width direction of the first thread-rolling plate 111, and the wide-direction guide rail and the wide-direction telescopic power 1133 are arranged side by side. One side of the wide-direction connecting plate 1132 is fixedly fastened to the wide-direction guide groove body, and the other side of the wide-direction connecting plate 1132 is arranged opposite to the wide-direction telescopic power 1133. The wide-direction telescopic power 1133 is connected to the wide-direction connecting plate 1132 and is used to drive the wide-direction connecting plate 1132 to slide along the wide-direction guide rail; the long-direction connecting plate 1135 is fixed to the wide-direction guide rail module 1131, the wide-direction connecting plate 1132, the long-direction connecting plate 1134, the long-direction slide rail module 1135, the long-direction connecting plate 1136, the long-direction connecting plate 1135, the long-direction connecting plate 1136, the long-direction connecting plate 1134, the long-direction slide rail module 1135, the long-direction slide rail module 1134, the long The wide connecting plate 1132 is located away from the wide telescopic power 1133.

The anti-jamming coil flattening power module 02 also includes a wheel system mounting block 29 and an elastic clamping unit 30. A first support block 281 is fixed to one side of the upper part of the wheel system mounting block 29, and a second support block 271 is fixed to the other side of the upper part of the wheel system mounting block 29. The wheel system mounting block 29 includes a rack mounting groove 291, which is formed inside the wheel system mounting block 29 and the groove opening of the rack mounting groove 291 penetrates one side wall of the wheel system mounting block 29. The rack 26 is slidably mounted in the rack mounting groove 291. The elastic clamping unit 30 includes a rolling clamping wheel 301 that passes through the groove opening of the rack mounting groove 291 and abuts against the toothless surface, and a clamping wheel for pressing the rack 26. The rolling clamping wheel 301 applies pressure to the compression spring 302; there are two rolling clamping wheels 301, and the two rolling clamping wheels 301 are respectively positioned opposite the driving gear 24 and the driven gear 25; the elastic clamping unit 30 also includes a roller connecting plate 303 and a connecting adjusting bolt 304; one end of the connecting adjusting bolt 304 is fixedly connected to the gear system mounting block 29, and the other end of the connecting adjusting bolt 304 passes through the roller connecting plate 303 and is slidably connected to the roller connecting plate 303; the compression spring 302 is sleeved on the connecting adjusting bolt 304, and both ends of the compression spring 302 abut against the gear system mounting block 29 and the roller connecting plate 303 respectively, and the rolling clamping wheel 301 is rotatably connected to the roller connecting plate 303.

[0080] In this embodiment, the elastic clamping wheel structure is formed by the combination of compression spring 302 and rolling clamping wheel 301, ensuring that rack 26 always slides close to gear, thus ensuring the meshing accuracy between gear and rack 26. Furthermore, the two rolling clamping wheels 301 are respectively positioned opposite the driving gear 24 and driven gear 25, which further improves the clamping effect. Using roller connecting plate 303 as the mounting body, the rolling clamping wheel 301, compression spring 302, and connecting adjusting bolt 304 are integrated into a modular structure, facilitating overall processing and installation. The connecting adjusting bolt 304 is used to fix the elastic clamping unit 30 to one side of the gear train mounting block 29. Changing the distance between the bolt head of the connecting adjusting bolt 304 and the gear train mounting block 29 also adjusts the clamping force of the rolling clamping wheel 301.

[0081] More specifically, the rolling clamping wheel 301 is a bearing; the roller connecting plate 303 is rectangular in shape, and each end of the roller connecting plate 303 has a recessed wheel groove 3031. A rolling clamping wheel 301 is installed in each wheel groove 3031. The roller connecting plate 303 has a recessed spring receiving groove 3032 on the side near the wheel system mounting block 29. There are four spring receiving grooves 3032, which are respectively located at the four corners of the roller connecting plate 303. Each spring receiving groove 3032 has a compression spring 302.

[0082] In this embodiment, with this structure, each rolling clamping wheel 301 is located between two compression springs 302, ensuring the uniformity of the clamping force of the rolling clamping wheel 301. Furthermore, the rolling clamping wheel 301 is accommodated by the wheel groove 3031, which improves the structural compactness. The spring receiving groove 3032 improves the stability of the spring position.

[0083] According to a specific embodiment of the present invention, a recessed block mounting groove 292 is provided on both sides of the strip mounting groove 291. The block mounting groove 292 is connected to the strip mounting groove 291. The anti-jamming coil flattening power module 02 also includes two sets of sliding stroke adjustment block units 31 respectively provided on both sides of the strip mounting groove 291. The sliding stroke adjustment block unit 31 includes a limiting block 311 and an adjusting stud 312. The lower part of the limiting block 311 is fixed in the block mounting groove 292 by a threaded connector. One end of the adjusting stud 312 is threadedly connected to the upper part of the limiting block 311. The other end of the adjusting stud 312 extends into the strip mounting groove 291. The adjusting stud 312 is set directly opposite the rack 26.

[0084] In this embodiment, the sliding stroke adjustment block unit 31 is integrated on the gear system mounting block 29 through the block mounting slot 292, which can limit the rack 26 and prevent it from coming out of the rack mounting slot 291; the extension stroke of the rack 26 can also be flexibly adjusted by adjusting the extension length of the adjusting stud 312.

[0085] In the hollow coil 100, among the multiple wire ends, the two wire ends located on both sides are designated as half-strand wire ends 103 to be twisted, and the wire end between the two half-strand wire ends 103 is designated as a full-strand wire end 104. The full-strand wire end 104 is a complete electrode wire end. The diameter of the two half-strand wire ends 103 to be twisted is generally half the diameter of the full-strand wire end 104. In subsequent processes, the two half-strand wire ends 103 to be twisted need to be twisted into a single full-strand wire end 104. The first clamping head plate 132 and the second clamping head plate 133 need to clamp two different diameter wire ends simultaneously. To ensure stable clamping, in this embodiment, a first adjustment window 1323 and a second adjustment window 1333 are provided. This ensures that the full-strand wire end 104 is clamped only at its upper and lower ends by the first upper clamping bar 1321 and the first lower clamping bar 1322, while the entire lower section of the half-strand wire end 103 to be twisted is clamped. In this way, the full-strand wire end 104 is easily flattened first, so that the thickness of the flattened full-strand wire end 104 is similar to the diameter of the half-strand wire end 103 to be twisted. Then, the first clamping head plate 132 and the second clamping head plate 133 simultaneously clamp wire ends of similar thickness, ensuring that the half-strand wire end 103 to be twisted is also firmly clamped. Ensuring that each wire end is firmly clamped during the flattening process helps to further improve the accuracy of coil flattening.
