Description

Technical Field

[0001] The utility model relates to the field of wrapping an enameled wire with an adhesive tape, in particular to a wrapping device with an adhesive tape. Background Art

[0002] Cross-wire means that the enameled wire 3 is wound around the next bobbin after being fully wound around the previous bobbin.

[0003] The purpose of cross-wire is to meet the needs of some customers, who need one or more enameled wires 3 to be wound on multiple skeletons at the same time, such as Figure 1 As shown, this is a schematic diagram of the cross-line.

[0004] It is not difficult to see from the figure that the enameled wire 3 is in contact with the next frame (as shown in F in the figure). This contact occurs when crossing the wire. This is because the structure of the frame has not made any adaptability improvements. Therefore, when using this frame that has not been specially optimized, some adaptability problems are inevitable. However, this adaptability problem will bring more unreliability to the product. For example, the thickness of the high-temperature tape itself is relatively thin. When the enameled wire 3 is dragged to the next frame, there is a sliding friction relationship between the high-temperature tape on the enameled wire 3 and the next frame, which causes the high-temperature tape to be worn, causing the enameled wire 3 inside the enameled wire 3 to leak out, and the produced winding has safety issues.

[0005] After research, it was found that the solution to this problem is to wrap one or more layers of high-temperature tape around the cross-wire position, so that the enameled wire 3 can be prevented from leaking out.

[0006] However, the winding is usually wound with not only one strand of enameled wire 3 but also multiple strands of enameled wire 3. Therefore, it is necessary to wrap a new high-temperature tape around all the strands of enameled wire 3. In principle, a new high-temperature tape is wrapped around each strand of enameled wire 3 separately. Considering the practicality, cost and difficulty of equipment redesign, winding multiple strands of enameled wire 3 at the same time can also avoid the problem of high-temperature tape scratching. At present, there is no equipment for wrapping new high-temperature tape around multiple enameled wires 3 at the same time. Utility Model Content

The second rotating pair is connected to the The third rotating pair is constructed to be rotationally connected with the connecting rod base and the fixed block.

[0013] Furthermore, it also includes a tape wrapping unit, which includes a main mechanism plate, a mounting seat, a tape support plate, a tape roll, a tape machine main board, a cylinder, a tape cutting assembly, and a tape pressing assembly.

[0043] like Figure 1 As shown, the area on the enameled wire 3 to be crossed is affected by various parameters such as the number of winding turns and the thickness of the enameled wire 3. Therefore, this area can be the front half and the back half of the enameled wire 3, or the middle part of the enameled wire 3. It can be clearly seen that this area does not belong to the beginning and end of the enameled wire 3.

[0044] Figure 2-3 A tape wrapping device is shown, which can achieve a winding effect on multiple enameled wires 3.

[0045] The tape wrapping device comprises a tape wrapping unit 1 and a tape feeding unit 2. The tape wrapping unit 1 comprises: a positioning mechanism 10 (such as Figure 11 As shown in the figure, and a bundle matrix 11 outside the enameled wire 3 and rotating around the enameled wire 3, the bundle matrix 11 is stretched onto the high-temperature tape of the enameled wire 3, the bundle matrix 11 has bendable flexibility and can maintain a shape in any bent state to counteract the above-mentioned high-temperature tape, when the bundle matrix 11 rotates on the positioning mechanism 10, it relies on it to maintain its bent shape to press the high-temperature tape onto the enameled wire 3.

[0046] As a result, the present invention realizes the winding of multiple enameled wires 3 using high-temperature tape. The bundle matrix 11 constituting the present invention also has another feature. Since the peripheral surface 3 of the enameled wire is not absolutely smooth, the arbitrary bending state of the bundle matrix 11 can adapt to the irregularities of the surface of the enameled wire 3, ensuring that the high-temperature tape can be effectively pressed even on a more complex or uneven surface, that is, the bendable flexibility of the bundle matrix 11 can fit the bumps on the enameled wire 3.

[0047] like Figure 4 、 5As shown in Figures 8, 9, 10, 11, 12, and 24, a rotating mechanism 12 is provided on the positioning mechanism 10. The rotating mechanism 12 rotates the telescopic connecting rod mechanism 13 connected to the bundle matrix 11 so that the bundle matrix 11 can rotate around the enameled wire 3.

[0048] The positioning mechanism 10 is a wire passing tube having a cavity with opening directions at both ends thereof, and the cavity has a space volume through which a plurality of enameled wires 3 pass.

[0049] The rotating mechanism 12 includes a rotating shaft 1201, a driven wheel 1202, a belt 1203, and a rotating motor 1204. The rotating shaft 1201 is sleeved on the wire passing tube, and the driven wheel 1202 is sleeved on the rotating shaft 1201. The rotating motor 1204 drives the driven wheel 1202 to rotate through the belt 1203. The rotating shaft 1201 rotates on the wire passing tube driven by the driven wheel 1202, thereby implementing the rotation of the bundle matrix 11 around the enameled wire 3.

[0050] In the tape wrapping unit 1, there is a telescopic link mechanism 13 for implementing the extension of the bundle matrix 11. The telescopic link mechanism 13 is used to meet two purposes at the same time. The primary purpose is to ensure that the axis 11a of the bundle matrix 11 and the axis 3a of the enameled wire 3 are maintained in a relatively perpendicular relationship during the extension and contraction process (such as Figure 13-14 As shown), in this way, when the bundle matrix 11 reaches the enameled wire 3, the stress on the bundle matrix 11 on the enameled wire 3 is balanced, that is, during the extension of the bundle matrix 11, it can prevent part of the bundle body 11b from contacting the enameled wire 3 in advance (as shown). Figure 15 As shown), this can prevent the portion of the harness body 11b from maintaining a relatively large phase change amplitude after the extension is completed, thereby optimizing the service life of the bundle matrix 11. In addition, when the enameled wire 3 is wrapped with the tape, it is in a straightened state. When the conductive material in the enameled wire 3 is copper wire, the behavior of the portion of the harness body 11b contacting the enameled wire 3 in advance will cause the enameled wire 3 to be significantly bent and deformed, and the enameled wire 3 will be in a straightened state, and there is a risk of the copper wire inside breaking.

[0051] Another purpose is to ensure that the bundle matrix 11 and the enameled wire 3 are kept in an appropriate space to facilitate the bonding between the high-temperature adhesive tape and the enameled wire 3 .

[0052] like Figure 4-5 As shown in Figures 16, 17, and 18, the telescopic link mechanism 13 includes a first rotation pair 1301, a second rotation pair 1302, a third rotation pair 1303, a push plate 1304, a push shaft 1305, a fixed block 1306, a bearing 1307, a bearing seat 1308, a tension spring 1309, and a connecting rod base 1310.

[0053] The push shaft 1305 is an annular structure that surrounds the entire rotating shaft 1201 and is located outside the rotating shaft 1201. The push shaft 1305 has a linear motion that moves in the direction of the wire hole 10a. The bearing 1307 is sleeved on the push shaft 1305. When the push shaft 1305 moves along the axial direction of the rotating shaft 1201, the entire bearing 1307 also moves along the axial direction of the rotating shaft 1201. The bearing seat 1308 is sleeved on the bearing 1307. The first rotating pair 1301 is constructed to be connected to the bearing seat 1308 and the fixed block 1306 for rotation. The second rotating pair 1302 is connected to the third rotating pair 1303. The movable pair 1303 is configured to be rotationally connected to the connecting rod base 1310 and the fixed block 1306. The connecting rod base 1310 is fixed to a portion of the rotating shaft 1201 near the wire hole 10a. The first ends of the first rotating pair 1301 and the second rotating pair 1302 share a common rotating shaft on the fixed block 1306. The second sections of the second rotating pair 1302 and the third rotating pair 1303 are respectively rotationally connected to the two end portions of the connecting rod base 1310. The first ends of the second rotating pair 1302 and the third rotating pair 1303 are respectively connected to two rotating shafts spaced apart on the fixed block 1306.

[0054] In the extended state, the position of the bearing 1307 is closer to the wire hole 10a relative to its initial position. At this time, the first rotating pair 1301 is maintained in a downward tilted state. This is because the limit position of the first rotating pair 1301 after being pushed is subject to the constraint of the rotation radius of the second rotating pair 1302, so that the bundle matrix 11 on the entire fixed block 1306 is pressed against the high-temperature tape on the enameled wire 3, and the introduction of the third rotating pair 1303 maintains the fixed block 1306 in a parallel state. The third rotating pair 1303 limits the fixed block 1306 from rotating, ensuring that the axis 11a of the bundle matrix 11 is relatively perpendicular to the axis 3a on the enameled wire 3. This relatively vertical relationship also continues throughout the retraction process. During the contraction process, the lifting path of the entire fixed block 1306 is arc-shaped, and the larger retraction space allows the enameled wire 3 to have a larger space around it to fit with the high-temperature tape.

[0055] The tension spring 1309 has a reset effect. The hooks on both ends of the tension spring 1309 are respectively connected to the rotating shaft 1201 and the side wall of the third rotating pair 1303. In the extended state, the tension spring 1309 is in a stretched state.

[0056] like Figure 19-20The source of power for the push plate 1304 to move is achieved through the cylinder 1311. A connecting plate 1312 is provided on the piston rod of the cylinder 1311. The connecting plate 1312 is connected to the push plate 1304. The push plate 1304 and the push shaft 1305 are fixedly connected, thereby maintaining the push shaft 1305 from contacting the rotating shaft 1201.

[0057] Among them, the area of ​​the push shaft 1305 corresponding to the bearing 1307 is the annular groove 1305-a, the inner ring of the bearing 1307 is embedded in the annular groove 1305-a, and the bearing seat 1308 is sleeved on the outer ring of the bearing 1307, and the bearing seat 1308 is in contact with the outer ring of the bearing 1307 so that the bearing seat 1308 can use the balls in the bearing 1307 to rotate.

[0058] like Figure 21-23 As shown, the tape feeding unit 2 includes a main mechanism plate 21, and a mounting seat 22 is provided on the top of the main mechanism plate 21. The mounting seat 22 is used to support the tape support plate 23, and the tape roll 24 is maintained in a suspended state through the tape support plate 23. The tape machine main board 25 is slidingly connected to the first side of the main mechanism plate 21, and a group of cylinders 26 on the above-mentioned first side control the reciprocating movement of the tape machine main board 25 on the main mechanism plate 21. The tape cutting assembly and the tape pressing assembly are arranged on the tape machine main board 25. The tape cutting assembly and the tape pressing assembly have a working path that intersects with the tape transportation path. The part of the tape pressing assembly tape close to the tape roll 24 is first tightened, and then the high-temperature tape is cut by the tape cutting assembly.

[0059] The transportation path of the high-temperature tape is guided by multiple rubber wheels 26. The rubber wheel 26 close to the enameled wire 3 is a fixed plate arranged on the main mechanism plate 21, and the remaining rubber wheels 26 are distributed on the components of the main mechanism plate 21. The fixed plate is an L-shape formed by connecting the first positioning part 27a and the first limiting part 27b. The first limiting part 27b is opposite to the pressing tape assembly, and the first positioning part 27a is connected to the main mechanism plate 21. The pressing tape assembly includes a pressing tape cylinder 28, a pressing tape slide rod 29, and a pressing tape sheet 30. The pressing tape cylinder 28 is connected to the pressing tape sheet 30 through the pressing tape slide rod 29, and the pressing tape sheet 30 presses the high-temperature tape on the first limiting part 27b.

[0060] The tape cutting assembly includes a cutter cylinder 31, a cutter slide 32, and a cutter 33. The cutter cylinder 31 drives the cutter 33 through the cutter slide 32 to cut the tape.

[0061] like Figure 6-7As shown, it also includes a clamping tape unit 4, which includes an upper clamping plate 41, a lower clamping plate 42, a finger cylinder 43, a linear moving component 44, and a connecting rod. The connecting rod is vertical and is provided with a pair, which are respectively connected to the side surfaces of the two clamping jaws of the finger cylinder 43, and the finger cylinder 43 is assembled to the output end of the linear moving component 44 based on the fact that when the clamping jaws move toward or away from each other, the connecting rod can only move longitudinally. The upper clamping plate 41 and the lower clamping plate 42 are arranged in an upper and lower relative manner. The first connecting rod 45 is connected to the upper clamping plate 41, and the second connecting rod 46 passes through the upper clamping plate 41 and is connected to the lower clamping plate 42. When the clamping jaws move toward each other, the upper clamping plate 41 and the lower clamping plate 42 are pulled together to clamp the tape.

[0062] In this embodiment, the tape wrapping mechanism is a double-station structure, and the tape clamping unit 4 is located between the two tape wrapping units 1. This tape clamping structure is in the form of upper and lower clamping, which can take into account the clamping of high-temperature tapes at two stations at the same time.

[0063] The bundle matrix 11 is bristles.

[0064] The operating principle of this utility model is as follows:

[0065] S1, in the initial state, the bristles are in the raised state;

[0066] S2, a plurality of enameled wires 3 are fed into the tape wrapping unit 1 through a motor wire feeding mechanism;

[0067] S3, the upper clamping plate 41 and the lower clamping plate 42 clamp the high-temperature tape from the transportation path of the high-temperature tape, drag the high-temperature tape toward the enameled wire 3, and place the adhesive side on the enameled wire 3;

[0068] S4, under the push of the push plate 1304, the entire fixed block 1306 moves toward the enameled wire 3, and under the air pressure inside the cylinder 1311, the bristles are pressed against the high-temperature tape on the enameled wire 3 in a deformed state;

[0069] S5, under the action of the rotating shaft 1201, the connecting rod base 1310 is driven to rotate. Through the auxiliary rotation effect provided by the bearing 1307, multiple rotating pairs are maintained in an extended state and rotate, thereby allowing the bristles to rotate around the enameled wire 3.

[0070] S6, after winding is completed, the tape is cut by the cutter 33.

[0071] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
