[0002] Currently, most small flat wire vertically wound coils on the market are round, but customers also need square coils. The main shaping principle of square coils is to wind the coil on a square shaft mold. Due to the influence of the arch force of the wire diameter and the tension of the winding during the square shaft winding, the coil shape obtained by this method is not square and cannot meet customer needs. Summary of the Invention

[0003] In view of this, the present invention provides a coil shaping device for solving the technical problem that a square coil cannot be obtained by winding the coil on a square shaft mold.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0005] A coil shaping device, comprising a bracket, a carrier, and a shaping mechanism, wherein the carrier is placed on the bracket, and a supporting position for placing the coil is provided on the carrier. Four through holes are opened on the circumference of the carrier corresponding to the supporting position, and the angle between any two adjacent through holes is 90 degrees.

[0006] The shaping mechanism is located on the side of the bracket away from the carrier. The shaping mechanism includes a carrying plate, a driving assembly and a shaping assembly. The carrying plate is provided with four slide grooves corresponding to the through holes, and the extension direction is arranged parallel to the through holes. The driving end of the driving assembly is connected to the carrying plate, and the driving assembly is used to drive the carrying plate to move closer to or away from the carrier. The shaping assembly includes:

[0007] Four clamping jaws are slidably disposed in each of the slide grooves, so as to be able to extend into each of the through holes when approaching the carrier. Each of the clamping jaws has an initial open position and a closed position for applying pressure to shape the coil along its sliding path. The side wall of each of the clamping jaws is inclined and faces the carrier.

[0008] an elastic module capable of causing each of the clamping jaws to have a tendency to move toward the open position;

[0009] And four pressure modules are fixed to the side of the bracket away from the carrier, and are arranged one by one on the moving path of each clamping jaw, so that when each clamping jaw approaches the carrier, it can abut against the side wall of the clamping jaw to move each clamping jaw from the open position to the closed position.

[0010] In some embodiments of the coil shaping device, the shaping device further includes a guiding mechanism, which is fixedly connected to the side of the bracket facing away from the carrier and is used to guide the movement of the bearing plate.

[0011] In some embodiments of the coil shaping device, the guiding mechanism includes a guiding frame and guide posts. The guiding frame is fixedly connected to the side of the bracket facing away from the carrier. One end of the guide post is connected to the bracket, and the other end is connected to the guiding frame. The bearing plate is sleeved on the guide posts; the driving assembly is fixedly connected to the guiding frame.

[0012] In some embodiments of the coil shaping device, four of the through holes around one bearing position form a group. The carrier is provided with a plurality of bearing positions and a plurality of groups of through holes corresponding to each bearing position are provided;

[0013] The number of the shaping assemblies is multiple, and each shaping assembly is arranged in one-to-one correspondence with each bearing position.

[0014] In some embodiments of the coil shaping device, the shaping device further includes a conveying mechanism, a pushing block and a positioning mechanism. The driving end of the conveying mechanism is connected to the pushing block. The conveying mechanism is used to drive the pushing block to reciprocate so as to be able to push the carrier to move. The positioning mechanism is located on the moving path of the carrier and corresponds to the shaping mechanism in position. The positioning mechanism is used to position the carrier.

[0015] In some embodiments of the coil shaping device, the carrier is provided with a positioning hole. The positioning mechanism includes a positioning driving module and a positioning member. The driving end of the positioning driving module is connected to the positioning member. The positioning driving module is used to drive the positioning member to approach or move away from the carrier so as to be able to insert the positioning member into the positioning hole to position the carrier.

[0016] In some embodiments of the coil shaping device, the bracket includes a support table and a frame body. The support table is fixedly connected to the frame body. A groove is formed on the support table to form a conveying channel capable of conveying and accommodating a plurality of carriers. A through strip hole is formed at the bottom of the groove;

[0017] The conveying mechanism is fixed to the side of the support table facing away from the carrier. A protrusion passing through the strip hole is provided on the side of the pushing block opposite to the support table so as to be able to push the carrier in the conveying channel to move.

[0018] In some embodiments of the coil shaping device, the length of the bar-shaped hole is a first interval, the length of the carrier in the driving direction of the conveying mechanism is a second interval, and the size of the pushing block in the driving direction of the conveying mechanism is a third interval. The first interval is greater than the sum of the interval and the two second intervals.

[0019] In some embodiments of the coil shaping device, a clamping groove is formed on one side of the carrier, and two notches communicating with the groove are formed on the side wall of the support platform so that the clamping groove can be exposed. The two notches are respectively located on both sides of the positioning mechanism.

[0020] The shaping device further includes two positioning mechanisms, and each positioning mechanism is correspondingly located at each notch position. The positioning mechanism includes a rotating block and a rolling block. The rotating block is rotatably arranged relative to the bracket through a torsion spring shaft, and the rolling block is rotatably connected to the rotating block. The rolling block is used to extend into the clamping groove.

[0021] In some embodiments of the coil shaping device, when both rolling blocks extend into the clamping groove, the distance between the two rolling blocks is twice the extension length of the carrier in the driving direction of the conveying mechanism.

[0022] Implementing the embodiments of the present invention will at least have the following beneficial effects:

[0023] The above-mentioned coil shaping device has the technical effect of shaping a square coil. Specifically, the coil shaping device of the present invention can drive four clamping jaws to extend into four through holes of the carrier through the action of the driving component. And in the process of the driving component driving the shaping mechanism towards the carrier, due to the inclined side walls of the clamping jaws and the pressure application module on the moving path of the clamping jaws, the four clamping jaws can gradually change from the open position to the closed position when approaching the carrier. In this way, the four clamping jaws can clamp the four sides of the coil to form a square coil, solving the technical problem that the existing method of winding the coil on a square shaft mold for shaping cannot obtain a square coil.

[0040] For the convenience of understanding the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many other different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0041] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there can also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for illustrative purposes.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0043] Here, it needs to be emphasized and explained that various connection methods involved in the present invention can be arbitrary when there is no specific description. For example, a fixed connection can be achieved by bolts and nuts for detachable fixation, welding or integral molding, etc., a sliding connection can be achieved by various-shaped grooves, guide rail structures, and a rotational connection can be achieved by hinges, rotating shafts, etc. Any existing methods capable of achieving the corresponding connection relationship are acceptable.

[0044] At present, most of the coils wound with small flat wires on the market are circular, as shown in Figure A in Figure 1 However, there is also a need for square coils in the client's requirements, as shown in Figure C in Figure 1 The main shaping device principle of the current square coil is to wind the coil wire on a square shaft mold. Due to the arching force of the wire diameter and the winding tension during the square shaft winding, one side correspondingly shows an arc-shaped protrusion, as shown in Figure B in Figure 1 As a result, the shape of the coil obtained by this method is not square and cannot meet the customer's requirements.

[0045] The following will further explain in detail the coil shaping device involved in the present invention in conjunction with Figures 2 - 6

[0046] In an embodiment of a coil 100 shaping device, the shaping device includes a bracket 1, a carrier 2, and a shaping mechanism. The carrier 2 is placed on the bracket 1. The carrier 2 is provided with a supporting position 21 for placing the coil 100. Four through holes 22 are provided on the circumference of the carrier 2 corresponding to the supporting position 21, and pass through the carrier 2. The angle between any two adjacent through holes 22 is 90 degrees. The shaping mechanism is located on the side of the bracket 1 away from the carrier 2. The shaping mechanism includes a supporting plate 3, a driving component 4, and a shaping component 5. The supporting plate 3 is provided with four slide grooves 31 corresponding to each through hole 22, and the extension direction is parallel to each through hole 22. The driving end of the driving component 4 is connected to the supporting plate 3, and the driving component 4 is used to drive the supporting plate 3 to move closer to or away from the carrier 2. The shaping assembly 5 includes four jaws 51 that are slidably mounted in corresponding positions within each slot 31, allowing them to extend into each through-hole 22 as they approach the carrier 2. Each jaw 51 has an initial open position and a closed position for applying pressure to the shaping coil 100 along its sliding path. The sidewalls of each jaw 51 are tilted and face the carrier 2. An elastic module 52 allows each jaw 51 to move toward the open position. Four pressure modules 53 are fixed to the side of the bracket 1 facing away from the carrier 2 and are positioned in corresponding positions along the movement path of each jaw 51. As each jaw 51 approaches the carrier 2, they abut against the sidewalls of the jaw 51, causing each jaw 51 to move from the open position to the closed position.

[0047] In this embodiment, the driving component 4 can drive the four clamping jaws 51 to extend into the four through holes 22 of the carrier 2, and in the process of the driving component 4 driving the shaping mechanism toward the carrier 2, due to the inclined setting of the side walls of the clamping jaws 51, the pressure module 53 on the moving path of the clamping jaws 51 can make the four clamping jaws 51 gradually change from the open position to the closed position in the process of approaching the carrier 2. In this way, the four clamping jaws 51 can clamp the four sides of the coil 100 to form a square coil 100, which solves the technical problem that the existing coil 100 cannot be wound on a square shaft mold to be shaped into a square coil 100.

[0048] It is understood that the pressure module 53 exerts pressure by cooperating with the drive assembly 4, thereby pressing against the sidewalls of the clamping jaw 51 and causing the clamping jaw 51 to slide inward. Specifically, the pressure module 53 can be a block-shaped structural member fixed to the bracket 1. To facilitate the contact, a bearing, roller, or other relatively rotatable structural member can be mounted on the block-shaped structural member. By forming a rolling pressure on the sidewalls of the clamping jaw 51, damage to the clamping jaw 51 itself can be reduced.

[0049] In addition, the drive assembly 4 can be a variety of modules, such as a pneumatic cylinder, an oil cylinder, a linear motor, a screw module, etc., so as to achieve reciprocating linear drive. The elastic module 52 can play the role of resetting the clamping jaws 51. The elastic module 52 can be a spring. The specific connection method can be various. For example, a central axis is set in the center of the four clamping jaws 51, and then four springs are set. One end of each spring is fixedly connected to the central axis, and the other end is fixedly connected to each clamping jaw 51 in a one-to-one correspondence. Alternatively, there can be only two springs, and the two ends of each spring are respectively fixed to the two opposing clamping jaws 51.

[0050] Preferably, when the four clamping jaws 51 are located at the initial open position, the distances between the clamping jaws 51 and the axis of the coil 100 are equal.

[0051] In an embodiment of the coil 100 shaping device, the shaping device further includes a guide mechanism 6 , which is fixedly connected to a side of the bracket 1 facing away from the carrier 2 and is used to guide the movement of the carrier plate 3 .

[0052] In this embodiment, the guide mechanism 6 is provided to guide the movement of the carrier plate 3, thereby improving the positioning accuracy. Specifically, the guide mechanism 6 can be guided in various ways, such as through guide grooves, guide rails and other structural forms.

[0053] In one embodiment of the coil shaping device 100, the guide mechanism 6 includes a guide frame 61 and a guide post 62. The guide frame 61 is fixedly connected to the side of the bracket 1 facing away from the carrier 2. The guide post 62 is connected to the bracket 1 at one end and to the guide frame 61 at the other end. The support plate 3 is mounted on the guide post 62. The drive assembly 4 is fixedly connected to the guide frame 61.

[0054] In this embodiment, the guide mechanism 6 is specifically a guide post 62. There can be two guide posts 62, each of which is provided at both ends of the carrier plate 3 to improve positioning accuracy. Furthermore, the drive assembly 4 can also be mounted on the guide frame 61, which helps to improve the matching accuracy.

[0055] Preferably, the supporting plate 3 can be configured to have a stepped shape, and the hole sleeved on the guide post 62 is opened on the stepped shape, so as to avoid separating the position of the hole and the sliding groove 31 and avoiding mutual interference.

[0056] In one embodiment of the coil shaping device 100, four through-holes 22 around a support position 21 form a group. The carrier 2 is provided with multiple support positions 21 and multiple groups of through-holes 22 corresponding to each support position 21. There are multiple shaping components 5, each corresponding to each support position 21.

[0057] In this embodiment, by providing multiple sets of through holes 22 and multiple shaping components 5, multiple square coils 100 can be shaped within one driving cycle of the driving component 4, thereby improving work efficiency. Specifically, referring to Figure 4 , the carrier 2 thereon has three carrying positions 21 and can shape three coils 100 at a time.

[0058] In an embodiment of a coil 100 shaping device, the shaping device further includes a conveying mechanism 71, a pushing block 72, and a positioning mechanism 8. The driving end of the conveying mechanism 71 is connected to the pushing block 72. The conveying mechanism 71 is used to drive the pushing block 72 to reciprocate so as to be able to push the carrier 2 to move. The positioning mechanism 8 is located on the moving path of the carrier 2 and corresponds to the shaping mechanism in position. The positioning mechanism 8 is used to position the carrier 2.

[0059] In this embodiment, it can be understood first that the positions corresponding to the positioning mechanism 8 and the shaping mechanism are shaping positions. By providing the conveying mechanism 71, the pushing block 72, and the positioning mechanism 8, a conveying line can be formed, so that the carrier 2 can be automatically conveyed to the shaping position, then positioned by the positioning mechanism 8, and then shaped by the shaping mechanism, which is beneficial to improving the automation level.

[0060] Specifically, the conveying mechanism 71 can be various linear driving modules 81 such as a cylinder, an oil cylinder, a linear motor, a lead screw module, etc.

[0061] In an embodiment of a coil 100 shaping device, the carrier 2 is provided with positioning holes 24. The positioning mechanism 8 includes a positioning driving module 81 and a positioning member 82. The driving end of the positioning driving module 81 is connected to the positioning member 82. The positioning driving module 81 is used to drive the positioning member 82 to approach or move away from the carrier 2 so as to be able to insert the positioning member 82 into the positioning hole 24 to position the carrier 2.

[0062] In this embodiment, the positioning is achieved by inserting the positioning member 82 into the positioning hole 24. Specifically, the number of positioning holes 24 can be two, and correspondingly, the number of positioning members 82 is also two. When both positioning members 82 are inserted into the positioning hole 24, the positioning is completed. Further specifically, the positioning hole 24 can be a round hole, and the positioning member 82 can be a round shaft.

[0063] In addition, in combination with the previous embodiments, it can be understood that the positioning mechanism 8 includes linear driving modules 81 such as a cylinder, an oil cylinder, and a linear motor. The positioning member 82 is arranged on a plate and is driven by the linear driving module 81 to be able to approach or move away from the carrier 2. The positioning member 82 and the driving component 4 are respectively located on opposite sides of the carrier 2.

[0064] In an embodiment of a coil 100 shaping device, the bracket 1 includes a support table 11 and a frame body 12. The support table 11 is fixedly connected to the frame body 12. A groove 111 is formed on the support table 11 to form a conveying channel capable of conveying and accommodating a plurality of carriers 2. A through strip-shaped hole 112 is formed at the bottom of the groove 111. The conveying mechanism 71 is fixed to the side of the support table 11 facing away from the carrier 2. A protrusion 721 passing through the strip-shaped hole 112 is provided on one side of the push block 72 relative to the support table 11, so as to be able to push the carrier 2 in the conveying channel to move.

[0065] In this embodiment, specifically, the bracket 1 as a whole can be a frame structure, including a support table 11 and a frame body 12. By providing a groove 111 on the support table 11, it is convenient to place the carrier 2, and the side wall of the groove 111 can also play a limiting role. In addition, by providing a through strip-shaped hole 112 at the bottom of the groove 111, it is convenient to hook the carrier 2 from the side facing away from the carrier 2 to drive the carrier 2 to move. It can be understood that the push block 72 moves reciprocally. During the reset process after pushing the previous carrier 2 away, instead of re-placing the carrier 2, the next carrier 2 can be placed after the push block 72 is reset. In this way, the reset movement of the push block 72 will not be interfered.

[0066] Combined with the previous embodiments, it should be noted here that in the previous embodiments, it is based on the support table 11 on different sides of the bracket 1.

[0067] Combined with the previous embodiments and the attached Figure 1 As shown, the driving directions of the driving component 4 and the positioning mechanism 8 are both in the vertical direction, that is, the Z direction, while the extending direction of the groove 111 is the X direction, and the extending direction of the sliding groove 31 is the Y direction.

[0068] In an embodiment of a coil 100 shaping device, the extending length of the strip-shaped hole 112 is a first interval, the length of the carrier 2 in the driving direction of the conveying mechanism 71 is a second interval, and the dimension of the push block 72 in the driving direction of the conveying mechanism 71 is a third interval. The first interval is greater than the sum of the interval and two second intervals.

[0069] In this embodiment, combined with Figure 2 and Figure 3 As shown, the extending lengths of the strip-shaped hole 112 and the push block 72, that is, the lengths along the X direction, and the length of the carrier 2 in the driving direction of the conveying mechanism 71 is also the length in the X direction. By setting the strip-shaped hole 112 to be larger than the sum of the sizes of two push blocks 72 and the length of the carrier 2, it can be ensured that there is enough space to place the carrier 2.

[0070] Specifically, the push block 72 can be a cylindrical structural member matching the end of the strip-shaped hole 112. Preferably, openings matching the shape of the push block 72 can be formed at both ends of the carrier 2.

[0071] In an embodiment of a coil 100 shaping device, a clamping groove 23 is formed on one side of the carrier 2, and two notches 113 communicating with the groove 111 are formed on the side wall of the support table 11 so that the clamping groove 23 can be exposed, and the two notches 113 are respectively located on both sides of the positioning mechanism 8. The shaping device further includes two clamping mechanisms 9, and each clamping mechanism 9 is correspondingly located at the position of each notch 113. The clamping mechanism 9 includes a rotating block 91 and a rolling block 92. The rotating block 91 is rotatably arranged relative to the bracket 1 through a torsion spring shaft, and the rolling block 92 is rotatably connected to the rotating block 91. The rolling block 92 is used to extend into the clamping groove 23.

[0072] In this embodiment, it can be understood that the rotating block 91 can rotate relative to the bracket 1 and is through a torsion spring shaft, so that a cooperation with the conveying mechanism 71 can be formed. The previous carrier 2 pushed by the conveying mechanism 71 through the push block 72 will be stuck by the rolling block 92, avoiding affecting the coil 100 being shaped. Then, the next carrier 2 pushed by the conveying mechanism 71 will push the previous carrier 2 towards the shaping position. At this time, the carrier 2 will break free from the clamping of the rolling block 92 and store energy in the torsion spring shaft. Then, when the next carrier 2 reaches the position, it will be stuck by the rolling block 92. Since the carriers 2 move one by one, when the rolling block 92 automatically rebounds and extends into the clamping groove 23, it also plays a certain positioning role, and higher positioning accuracy can be achieved in cooperation with the positioning mechanism 8.

[0073] Specifically, the rolling block 92 can be a roller or a bearing, and the rotating block 91 can be L-shaped, with one end rotatable relative to the bracket 1 through a torsion spring shaft and the other end mounting the rolling block 92. In addition, it should be noted that the rotating block 91 can be rotatably connected to the bracket 1 through a torsion spring shaft, or other structural components, or externally mounted on another frame, as long as the rotating block 91 can rotate relative to the bracket 1 through the torsion spring shaft.

[0074] In addition, it can be understood that the torsion spring shaft can be an existing component, that is, a shaft-like structural member with elastic resilience, or a combination of a torsion spring and a shaft, and their principles are the same.

[0075] In an embodiment of a coil 100 shaping device, when both rolling blocks 92 extend into the clamping groove 23, the distance between the two rolling blocks 92 is twice the extension length of the carrier 2 in the driving direction of the conveying mechanism 71.

[0076] In this embodiment, it can be understood that the distance between the two rolling blocks 92 is the length of two carriers 2 in the X direction. When both rolling blocks 92 are stuck in the clamping groove 23, there is still one carrier 2 in the middle, and the middle carrier 2 corresponds to the shaping position. Such an arrangement makes the overall device more compact, can improve the positioning accuracy, and is beneficial to improving the automation level.

[0077] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0078] The above embodiments only express several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
