Description

Technical Field

[0001] This utility model belongs to the technical field of binding devices, specifically an Alpha coil tape binding and shaping device. Background Technology

[0002] Alpha coils refer to a unique winding method that is widely used in the field of wireless charging. The wires using the alpha winding method are usually quite thick and will be very loose if not fixed. Self-adhesive wire is usually used as the base material. The characteristic of self-adhesive wire is that its outer sheath becomes sticky after being heated. So after the coil is wound, it is heated again to make the stacked wires stick together and prevent them from becoming loose.

[0003] However, this has limitations. It requires the use of self-adhesive wire as the base material, but according to the customer's requirements, the alpha coil needs to be wound with non-self-adhesive wire. The solution to prevent the wires from loosening is to use tape to bind them, but manual binding is very inefficient. Utility Model Content

[0008] The binding assembly has a first notch for the coil to enter, and a switching assembly is installed on one side of the binding assembly. The switching assembly is used to switch the binding assembly to either a rotating or binding state.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please refer to Figure 1-6 ;

[0029] The tape binding described in this utility model belongs to the later stage of coil winding process, aiming to improve the efficiency of the later stage production. Although there are similar winding technology solutions in the prior art as disclosed in the technical documents "CN115410777B, a bare wire tape winding device 15" and "CN116946819A an automatic tape winding device", the device described in this utility model, when combined with the winding device in actual application, provides very little space. The tape cannot be directly fed into the winding device. Instead, the winding device needs to obtain a certain length of tape before winding. Therefore, the technical solutions in the above-mentioned documents cannot be applied here.

[0030] The specific solution of this utility model includes a fixed base 1, on which a driving component 2 and a binding component 3 are installed; the driving component 2 is used to drive the binding component 3 to rotate as a whole to obtain tape, and the internal components of the binding component 3 to perform binding operations; a switching component 4 is installed on one side of the binding component 3; the binding assembly in this embodiment has two states: obtaining tape and binding tape, and both are powered by the same driving component 2.

[0031] First, the binding component 3 needs to acquire the tape. At this time, the binding component 3 is switched to the first state by the switching component 4, so that the binding component 3 is connected to the driving component 2. The driving component 2 drives the binding component 3 to rotate, so that the first notch 32 moves closer to the clamping component 5 and clamps a section of the tape. Then, the driving component 2 drives the binding component 3 to rotate and reset, while pulling the tape a certain length. Finally, the cutting component 6 cuts the tape. After the binding component 3 is reset, the tape covers the top of the first notch 32, completing the first stage of the tape acquisition process. It should be noted that the adhesive side of the tape body is facing upward.

[0032] Once the coil passes through the first notch 32 and enters the binding assembly 3, the switching assembly 4 switches the binding assembly 3 to the second state, fixing the housing 31 of the binding assembly 3 to its current position to prevent displacement when binding tape. Meanwhile, the device inside the binding assembly 3 can be driven by the driving assembly 2 to wrap the tape around the coil.

[0033] Existing winding assemblies typically include tape output functionality, resulting in a large overall size that makes them unsuitable for use in confined spaces. This invention, however, employs an independent feeding method, making the winding device thinner and applicable to narrow spaces. It can be integrated with a winding machine, directly binding the wire with tape after winding to form an alpha coil from a non-self-adhesive wire. Furthermore, the coil does not need to be transferred, preventing it from becoming loose and significantly improving production efficiency.

[0034] In one embodiment of the binding assembly 3 of this utility model, a housing 31 is specifically provided. The housing 31 has a first notch 32 for the coil to enter. An operating gear ring 331, several driven gears 332, and a driving gear 333 are rotatably connected within the housing 31 and mesh sequentially. It should be noted that the operating gear ring 331 has a certain thickness and a groove matching the tape is provided along its circumference. The operating gear ring 331 can be understood as consisting of three parts: the groove body is located in the middle, and two toothed plates are located on both sides of the groove body. Additionally, the housing 31 has an arc-shaped limiting groove adapted to it. Several driven gears 332 are rotatably connected to the housing 31 via shafts. Specifically, there are four driven gears, which mesh on both sides of the operating gear ring 331, serving a supporting and transmission function. The driving gear 333 is connected to the drive assembly 2. The operating gear ring 331 has a second notch 334 corresponding to the first notch 32.

[0035] The connecting rod 342 is placed in the housing 31 and slidably connected thereto. That is, a limiting groove is provided in the housing 31, and the connecting rod 342 is placed in the limiting groove so that it can only move telescopically. The telescopic movement direction of the connecting rod 342 is the same as the orientation of the first notch 32. A first cylinder 341 is installed on the outside of the housing 31. A connecting piece 344 is provided at the output end of the first cylinder 341. The connecting piece 344 extends into the housing 31 and connects with the connecting rod 342. Of course, a movable groove communicating with the limiting groove is provided on one side of the housing 31 for the connecting piece 344 to move.

[0036] The connecting rod 342 is L-shaped, and its end can abut against the first fixing block 343. The first fixing block 343 is located in the housing 31 near the first notch 32. The connecting rod 342 cooperates with the first fixing block 343 to form a clamping position 345.

[0037] In the initial state, one end of the connecting rod 342 is away from the first fixing block 343, allowing the tape to be placed between the two. Then, the first cylinder 341 drives the connecting rod 342 to move closer to the first fixing block 343 and abut against it to clamp the tape. Preferably, a concave-convex structure is provided between the first fixing block 343 and the end of the connecting rod 342 to better clamp and fix the tape. Afterward, the driving component 2 drives the binding component 3 to rotate as a whole, thereby pulling the tape so that it covers the surface of the first notch 32.

[0038] In addition, in the initial state, the switching component 4 locks the housing 31 to the output shaft 21 of the drive component 2. When the drive component 2 rotates, the housing 31 and the gear assembly inside it will also rotate synchronously. At this time, the housing 31 and the gear assembly are relatively stationary. When it is necessary to bind tape, the switching component 4 disconnects the housing 31 from the output shaft 21 of the drive component 2 and connects the housing 31 to the external fastener. In this state, the housing 31 is locked and cannot move, while the output shaft 21 of the drive component 2 can rotate relative to the housing 31 and drive the gear assembly to rotate.

[0039] Further explanation of the switching component 4 includes a fixed housing 41, which can be connected to the fixed base 1 or other external fasteners, as long as it remains stationary; the output shaft 21 of the drive component 2 passes sequentially through the drive gear 333, the first locking block 42 and the second locking block 43, the second locking block 43 is fixedly connected to the fixed housing 41 and rotatably connected to the output shaft 21 of the drive component 2, and the first locking block 42 is fixedly connected to the output shaft 21 of the drive component 2;

[0040] A second cylinder 44 is installed on the outer wall of the housing 31. The output end of the second cylinder 44 passes through the housing 31 and is fixed with a locking block 45. The locking block 45 can be engaged with the first locking block 42 and the second locking block 43 respectively. The engaging and fixing method can be a slot and a block. The locking block 45 is located on the outside of the first locking block 42 and the second locking block 43 respectively.

[0041] When tape needs to be obtained, the second cylinder 44 is in a retracted state, causing the engaging block 45 to engage with the first locking block 42. Since the second locking block 43 is fixedly connected to the output shaft 21, at this time it is equivalent to the housing 31 being rotatably connected to the output shaft 21. While the drive assembly 2 drives the output shaft 21 to rotate, the housing 31 and each gear rotate synchronously. When a binding operation is required, the second cylinder 44 extends to push the engaging block 45 to disengage from the first locking block 42 and to be fixed to the second locking block 43. It should be noted that after the engaging block 45 is fixed to the second locking block 43, it will not interfere with the first locking block 42. At this time, the housing 31 is no longer locked to the output shaft 21, but locked to the fixed housing 41. When the output shaft 21 rotates, since the housing 31 is fixed and the drive gear 333 is not fixed, the output shaft 21 can drive the drive gear 333 to rotate relative to the housing 31, thereby driving each gear to complete the binding operation.

[0042] In embodiments of this utility model, since the tape needs to be cut before the binding operation, and the binding component 3 only fixes one end of the tape, the free end of the tape will swing during the resetting process of the binding component 3. This causes the tape to be unable to accurately cover the surface of the first notch 32 or the second notch 334, resulting in the inability to complete the binding operation. Therefore, this utility model proposes the following solution:

[0043] The housing 31 has a first hole 35 for the clamping assembly 5 to pass through on the side near the first notch 32, and a clearance position 36 for the clamping assembly 5 to extend into is formed in the housing 31. The clamping position 345 is located on the side opposite to the first hole 35.

[0044] Before clamping the tape, the drive assembly 2 drives the binding assembly 3 to rotate. Assuming a 90° rotation is required, the first notch 32 and the end of the clamping assembly 5 both face upwards, while the first hole 35 is located on one side. The drive assembly 2 drives the binding assembly 3 to rotate 90°, as shown in the diagram. Figure 5 and Figure 6 The end of the clamping assembly 5 enters the interior of the housing 31 through the first hole 35 and collides with the operating gear in the clearance position 36. After fully extending into the housing 31, the end of the clamping assembly 5 corresponds to the clamping position 345. With the cooperation of the first fixing block 343 and the connecting rod 342, the tape is clamped and fixed. Then, the binding assembly 3 is reset by the drive assembly 2. During this process, not only will the tape be pulled, but the clamping assembly 5 will also be pushed out of the housing 31. At this time, the tape will pass through the first hole 35. The first hole 35 plays a limiting role for the tape, so that it will not swing or deviate, ensuring that the tape is located at the first notch 32 and above the second notch 334.

[0045] One embodiment of the present invention relates to the clamping assembly 5, specifically including a fixing plate 51, a pneumatic gripper 52 mounted on the fixing plate 51, a clamping arm 53 mounted on the moving end of the pneumatic gripper 52, and a conveying channel 54 formed between the two clamping arms 53 for the tape to pass through.

[0046] Preferably, a storage tray 71 is provided below the clamping assembly 5, and a roller 72 is connected to the fixed base 1. The tape passes through the roller 72 and extends into the conveying channel 54, and is then clamped and fixed by the ends of the two clamping arms 53. Of course, manual feeding is required before the first use. A small part of the tape will protrude from the ends of the clamping arms 53 for being picked up by the clamping position 345 in the binding assembly 3.

[0047] In addition, the tape in this embodiment is very soft and cannot stand up without external force, making it difficult for the clamping component to grasp. Therefore, a squeezing structure 55 is provided at the ends of the two clamping arms 53. After the binding component 3 is reset and the tape is pulled out, the pneumatic gripper 52 drives the clamping arms 53 to reset. At this time, the squeezing structure 55 at the ends of the clamping arms 53 fits and squeezes the tape, causing it to deform and shrink inward. This can be understood as a piece of white paper that cannot stand up without external force, but can stand up after being bent into an arc shape to form a semi-cylindrical shape. Finally, the tape is cut by the cutting component 6.

[0048] One embodiment of the present invention relates to the cutting component 6, see reference to Figure 2 and Figure 6 Specifically, it includes a third cylinder 61 installed on the other side of the fixed plate 51. The output end of the third cylinder 61 is provided with a connecting block 62. The connecting block 62 is provided with a second hole 63. A lever component 64 is provided in the second hole 63. The lever component 64 is fixedly connected to the rotating shaft 65. The rotating shaft 65 is rotatably connected to the second fixed block 66. The second fixed block 66 is fixedly connected to the fixed plate 51. A cutting component 67 is fixedly provided at the end of the rotating shaft 65. The extension and retraction of the third cylinder 61, in conjunction with the connecting block 62, causes the lever component 64 to move, which in turn causes the rotating shaft 65 to rotate, thereby realizing the swinging action of the cutting component to complete the cutting operation.

[0049] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
