Description

Technical Field

[0001] This invention relates to the field of winding copper foil, and more particularly to a copper foil wrapping device and a copper foil wrapping method. Background Technology

[0002] Normally, the windings on the coils are made of copper wire. However, in some special operating environments, it is necessary to wrap a layer of copper foil between the two layers of copper wire. The size of the copper foil is much larger than that of the copper wire. For example, the copper foil is a rectangular strip with a width of ±5cm. Compared to the copper wire, the larger size brings the characteristic of not being easily deformed. Obviously, traditional copper wire winding equipment cannot achieve the winding of copper foil on the frame. In addition, it does not have the winding method of winding copper foil on the original copper wire. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a copper foil wrapping device capable of winding large-sized copper foil onto a frame.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: a copper foil wrapping device, characterized in that it includes the following structure:

[0005] The main spindle mechanism has its output end connected to one end of the fixture, and the fixture is fitted with a frame.

[0006] The copper foil winding section is used to wind copper foil onto the skeleton at the output end of the main spindle mechanism. The copper foil winding section includes a first platform, a central push rod mechanism, a copper foil pressing mechanism, and a second platform. The output shaft of the central push rod mechanism and the fixture on the main spindle mechanism are opposite to each other. The central push rod mechanism has a trajectory for moving towards the fixture, and its output end is used to abut against the other end of the fixture. The first platform is located between the output end of the central push rod mechanism and the output end of the main spindle mechanism. The second platform is formed by end-fitting with the first platform. The first platform has a liftable movement trajectory. The first platform and the second platform have tracks adapted to the size of the copper foil. The output end of the copper foil pressing mechanism is located at the end position of the track on the first platform and abuts against the copper foil on the skeleton.

[0007] The tape application section includes a set of tape application mechanisms distributed on both sides of the first platform. The tape application mechanisms have movable tracks that extend to both ends of the copper foil, for applying tape to both ends of the copper foil on the first platform.

[0008] Furthermore, the copper foil winding section also includes a flattening mechanism for pre-pressing the copper foil on the second platform track. The flattening mechanism is distributed in the side area of ​​the second platform and includes a connecting rod, a pressure head, and a leveling cylinder. The connecting rod is rotatably mounted on the second platform, with its outer end connected to the pressure head. The output end of the leveling cylinder is rotatably connected to the inner end of the connecting rod and has a direction that causes the outer end of the connecting rod to rotate toward the aforementioned second platform track.

[0009] Furthermore, the central push rod mechanism includes a push head and a driven rotating assembly. The push head is connected to the movable end of the driven rotating assembly, and the end of the push head is tapered.

[0010] Furthermore, the copper foil pressing mechanism includes a copper foil pressing cylinder, a second pressing roller, and a sliding assembly. The output end of the copper foil pressing cylinder is connected to the second pressing roller through the sliding assembly, and the copper foil pressing cylinder has a direction to push the second pressing roller to the aforementioned end position.

[0011] Furthermore, the tape applicator is used to apply the adhesive side of the tape to the end of the copper foil on the first platform. The tape applicator includes a first linear moving component, and a tape pressing component, a flipping component, and a cutting component connected to the output end of the first linear moving component. The cutting component is located between the tape pressing component and the flipping component. The tape pressing component has a rolling part that presses the tape onto the copper foil. The flipping component has a rotatable first baffle with a length that extends beyond the cutting component, and is used to press the tape cut by the cutting component onto the rolling part.

[0012] Furthermore, the cutter assembly includes a sliding seat, a pressure plate, a cutter, a first driving component, and a second driving component. The cutter and the sliding seat are slidably connected. The pressure plate is connected to the end of the sliding seat. The output end of the first driving component is connected to the cutter, and the output end of the second driving component is connected to the inner end of the sliding seat.

[0013] Furthermore, the pressure tape assembly includes a first pressure roller, a mounting plate, a connector, a spring, and a positioning plate. The connector passes through the positioning plate and is connected to the mounting plate. The spring is sleeved on the connector and is located between the positioning plate and the mounting plate. The first pressure roller is connected to the mounting plate.

[0014] Furthermore, the flipping assembly also includes a swing arm, a flipping cylinder, and a bearing housing. The flipping cylinder has a pushing direction for moving towards the swing arm. The output end of the flipping cylinder is connected to the bearing housing, which is provided with a bearing. One end of the swing arm is connected to the output end of the first linear movement assembly, and the other end is connected to the first baffle.

[0015] Furthermore, it also includes a wire unwinding mechanism and a wire storage mechanism. The wire unwinding mechanism is used to unwind the copper wire wound on the fixture. The wire unwinding mechanism includes a rotary cylinder disposed on the output end of the second linear movement component, and a pneumatic finger and wire cutting assembly disposed on the output end of the rotary cylinder. The wire storage mechanism is located above the main spindle mechanism. The wire storage mechanism includes a wire guide wheel and a telescopic cylinder. The output end of the telescopic cylinder is connected to the wire guide wheel, so that the wire guide wheel can move longitudinally.

[0016] Furthermore, it also includes a storage mechanism adjacent to the first platform. The storage mechanism includes a base plate and multiple second baffles and baffles. The second baffles and baffles are disposed on the surface of the base plate and form a space for wrapping the copper foil.

[0017] The beneficial effects of this invention are:

[0018] 1. First, the present invention realizes the winding of copper foil, mainly by means of a copper foil pressing mechanism and a spindle mechanism, which apply pressure to the copper foil on the skeleton from the end position of the track, thereby causing the copper foil to bend and form a winding result on the skeleton.

[0019] 2. Secondly, the central push rod mechanism of this invention can stabilize the position of the fixture. The fixture is suspended in the air, and the central push rod mechanism abuts against the fixture, which can resist the pressure applied by the copper foil pressing mechanism. For fixtures, which are high-precision parts, the use of the central push rod mechanism can effectively prevent the fixture from deforming.

[0020] 3. Furthermore, due to the high hardness of copper foil, the power source for bending copper foil includes the power of the spindle rotating the fixture and the power of the copper foil pressing mechanism applying pressure. The spindle mechanism acts on the inner surface of the copper foil, while the copper foil pressing mechanism acts on the outer surface of the copper foil. This combination of inner and outer mechanisms greatly reduces the difficulty of bending copper foil. Moreover, there are no gaps between copper foils, and similarly, there are no gaps between the copper foil and the frame. In addition, this implementation method makes the surface of the copper foil smoother.

[0021] 4. The mechanism, setting position, and movement trajectory selected in this invention are all special choices made to enable the winding of copper foil on the skeleton with the first layer of wire, so as to meet the requirements of winding copper foil on the wire.

[0040] A copper foil wrapping device, such as Figure 1-2 As shown, the feature is that it includes the following structure disposed on the frame plate 100:

[0041] The transport mechanism 1 has a placement box 1-A on its output end for placing a fixture 1-B with a frame 1-C.

[0042] The main spindle mechanism 2 has its output end connected to one end of the fixture 1-B, and the fixture 1-B is fitted with a skeleton 1-C.

[0043] like Figure 5As shown, the copper foil winding section 3 is used to wind the copper foil 1-D onto the skeleton 1-C on the output end of the main spindle mechanism 2. The copper foil winding section 3 includes a first platform 31, a central push rod mechanism 32, a copper foil pressing mechanism 33, and a second platform 34. The output shaft of the central push rod mechanism 32 is opposite to the fixture 1-B on the main spindle mechanism 2. The central push rod mechanism 32 has a trajectory for moving towards the fixture 1-B, and its output end is used to abut against the other end of the fixture 1-B. The first platform 31 is located between the output end of the central push rod mechanism 32 and the output end of the main spindle mechanism 2. The second platform 34 is formed by end-fitting with the first platform 31. The first platform 31 has a movable trajectory that can be raised and lowered. The first platform 31 and the second platform 34 have tracks adapted to the size of the copper foil 1-D. The output end of the copper foil pressing mechanism 33 is located at the end position of the track and abuts against the copper foil 1-D on the skeleton 1-C.

[0044] The tape application section includes a set of tape application mechanisms (41, 42), which are distributed on both sides of the first platform 31. The tape application mechanisms (41, 42) have a moving trajectory that moves to both ends of the copper foil 1-D, and are used to apply tape to both ends of the copper foil 1-D on the first platform 31.

[0045] First, the present invention realizes the winding of copper foil 1-D, mainly by using the copper foil pressing mechanism 33 and the main shaft mechanism 2 to apply pressure to the copper foil 1-D on the skeleton 1-C from the end position of the track, thereby enabling the copper foil 1-D to be bent and form a winding result on the skeleton 1-C.

[0046] Secondly, the central push rod mechanism 32 of this invention can stabilize the position of the fixture 1-B. The fixture 1-B is suspended, and the central push rod mechanism 32 abuts against the fixture 1-B, which can resist the pressure applied by the copper foil pressing mechanism 33. For fixture 1-B, which is a high-precision component, the use of the central push rod mechanism 32 can effectively prevent the fixture 1-B from deforming.

[0047] Furthermore, since the copper foil 1-D has relatively high hardness, the power source for bending the copper foil 1-D includes the power of the spindle mechanism 2 to rotate the fixture 1-B, and the power of the copper foil pressing mechanism 33 to apply pressure. The spindle mechanism 2 acts on the inner surface of the copper foil 1-D, and the copper foil pressing mechanism 33 acts on the outer surface of the copper foil 1-D. This combination of inner and outer forces greatly reduces the difficulty of bending the copper foil 1-D. In addition, this implementation method makes the surface of the copper foil 1-D smoother.

[0048] The mechanism, its location, and its trajectory selected in this invention are all specially chosen to enable the winding of copper foil 1-D on the skeleton 1-C with the first layer of wire, thus meeting the requirement of winding copper foil 1-D on the first layer of wire.

[0049] like Figure 6 As shown, the copper foil winding section 3 further includes a flattening mechanism 35 for pre-pressing the copper foil 1-D on the track of the second platform 34. The flattening mechanism 35 is distributed in the side area of ​​the second platform 34. The flattening mechanism 35 includes a connecting rod 3501, a pressing head 3502, and a leveling cylinder 3503. The connecting rod 3501 is rotatably mounted on the second platform 34. The outer end of the connecting rod 3501 is connected to the pressing head 3502. The output end of the leveling cylinder 3503 is rotatably connected to the inner end of the connecting rod 3501 and has a direction to rotate the outer end of the connecting rod 3501 towards the track of the second platform 34. Because the length of the copper foil 1-D is too long, the initial winding will cause the part of the copper foil 1-D corresponding to the second platform 34 to deviate. At this time, the pressing head 3502 can position the copper foil 1-D. In addition, the copper foil 1-D has In cases of partial warping, gaps exist between layers of copper foil 1-D during winding on the bobbin 1-C. The pressure head 3502 applies pressure to the copper foil 1-D, which flattens the copper foil 1-D and reduces these gaps, improving the stability of the winding structure. Furthermore, after the copper foil 1-D is wound, it needs to be rewound. The outermost layer of copper foil 1-D on the winding is the part of the original copper foil 1-D corresponding to the second platform 34. After flattening, this part of the copper foil 1-D is flat. At this time, there will be no unevenness between the turns of copper wire in each layer of copper wire, and there will be no interference with the magnet during subsequent assembly. (The number of copper wires in the winding can be multiple groups or a single group. In this embodiment, there are two groups of copper wires.)

[0050] like Figure 7 As shown, the central push rod mechanism 32 further includes a push head 3201 and a driven rotating assembly. The push head 3201 is connected to the movable end of the driven rotating assembly, and the end of the push head 3201 is tapered. The push head 3201 provides additional support to prevent the fixture 1-B from sagging or tilting due to gravity or inertia during rotation. Another advantage is that it can effectively reduce the vibration generated when the fixture 1-B rotates, thereby improving the overall stability and reliability of the copper foil 1-D.

[0051] like Figure 8As shown, the copper foil pressing mechanism 33 further includes a copper foil pressing cylinder 3301, a second pressing roller 3302, and a sliding assembly 3303. The output end of the copper foil pressing cylinder 3301 is connected to the second pressing roller 3302 through the sliding assembly 3303. The copper foil pressing cylinder 3301 has a direction to push the second pressing roller 3302 to the aforementioned end position. Since the copper foil 1-D is not easily deformed, and the main shaft mechanism 2 forms a preliminary arc-shaped profile for the copper foil 1-D, there is a situation where the copper foil 1-D and the skeleton 1-C are not in contact. At this time, the second pressing roller 3302 applies pressure to the outside of the copper foil 1-D, so that the copper foil 1-D is in contact with the copper foil 1-D. In addition, it can also make the copper foil 1-D and the skeleton 1-C in contact.

[0052] like Figure 9-12 As shown, further, the tape-applying mechanism 41 is used to apply the adhesive side of the tape to the end of the copper foil 1-D on the first platform 31. The first tape-applying mechanism 41 includes a first linear movement component 411. In this embodiment, the first linear movement component 411 is connected to the guide component 413, the tape-pressing component 414, the flipping component 415, and the cutter component 416 via the main board 412. The cutter component 416 is located between the tape-pressing component 414 and the flipping component 415. The guide component 413 is adjacent to one side of the flipping component 415 and has a direction for feeding the tape towards the flipping component 415. The tape assembly 414 has a rolling part that presses the tape onto the copper foil 1-D. The flipping assembly 415 has a first baffle 4103 that is rotatably connected to the main board 412. The first baffle 4103 has a length that exceeds that of the cutter assembly 416 and is used to press the tape cut by the cutter assembly 416 onto the rolling part. The above solution is to allow the tape to be smoothly applied to the rolling part. The cutter assembly 416 is located between the flipping assembly 415 and the tape pressing assembly 414. The first baffle 415-A in the flipping assembly 415 and its rotatable movement allow the cut tape to be pushed onto the rolling part, and the rolling part can then press the tape onto the copper foil 1-D.

[0053] The aforementioned guide assembly 413 is composed of multiple guide rollers 413-A and a reel 413-B.

[0054] like Figure 9-12As shown, in this embodiment, the cutter assembly 416 includes a guide block 416-A, a sliding seat 416-B, a pressure plate 416-C, a cutter 416-D, a first driving component, and a second driving component. The cutter 416-D and the sliding seat 416-B are slidably connected. The pressure plate 416-C is connected to the end of the sliding seat 416-B. The output end of the first driving component is connected to a first guide rod 416-E, which passes through a first guide opening in the guide block 416-A and is connected to the cutter 416-D. The output end of the second driving component is connected to a second guide rod 416-F, which passes through a second guide opening in the guide block 416-A and is connected to the sliding seat 416-D. The inner end of B is connected; the function of the sliding seat 416-B includes the following two points: First, it provides support. The sliding seat 416-B can move on the movement trajectory of the first baffle 415-A. The adhesive surface of the tape faces the outer end face of the first baffle 415-A. At this time, the first baffle 415-A pushes the tape towards the sliding seat 416-B. After reaching the sliding seat 416-B, the adhesive surface connects with the outer end face of the first baffle 415-A, and the tape also sticks to the first baffle 415-A. At this time, the position of the tape can be controlled. By controlling the rotation amplitude of the first baffle 415-A, the tape is finally pushed onto the rolling part, thereby determining the contact relationship between the tape and the rolling part.

[0055] like Figure 12 As shown, the tape pressing assembly 414 further includes a first pressure roller 414-A, a mounting plate 414-E, a connector 414-C, a spring 414-B, and a positioning plate 414-D. The connector 414-C passes through the positioning plate 414-D and is connected to the mounting plate 414-E. The spring 414-B is sleeved on the connector 414-C and is located between the positioning plate 414-D and the mounting plate 414-E. The first pressure roller 414-A is connected to the mounting plate 414-E. In this embodiment, the mounting plate 414-E is connected to the sliding block main plate 412 via a slide rail. When the first pressure roller 414-A presses against the tape, the spring 414-B will deform. After the pressure on the first pressure roller 414-A ends, the spring 414-B returns to its original position.

[0056] Furthermore, such as Figure 13As shown, the flipping assembly 415 further includes a swing arm 415-B, a flipping cylinder 415-C, a bearing seat 415-D, and a connecting shaft 415-E located on the back of the main board 412. A first baffle 415-A is located on the surface of the main board 412. One end of the connecting shaft 415-E passes through the main board 412 and is connected to the first baffle 415-A. The flipping cylinder 415-C has a pushing direction to move towards the swing arm 415-B. The output end of the flipping cylinder 415-C is connected to the bearing seat 415-D, which is provided with a bearing. One end of the swing arm 415-B is rotatably connected to the main board 412, and the other end is connected to the connecting shaft 415-E. The first baffle 415-A is driven by an active mechanism. In addition, using a bearing to push the swing arm 415-B can reduce the wear on the swing arm 415-B.

[0057] like Figure 3 , 5 As shown in Figures 9 and 14, the device further includes a wire unwinding mechanism 5 and a wire storage mechanism 6. The wire unwinding mechanism 5 is used to unwind the copper wire wound on the fixture 1-B. The wire unwinding mechanism 5 includes a rotary cylinder 51 disposed on the output end of the first linear movement assembly 411, a pneumatic finger 52 disposed on the output end of the rotary cylinder 51, and a pneumatic scissors 53. Located above the main shaft mechanism 2, the wire storage mechanism 6 includes a wire guide wheel 61 and a telescopic cylinder 62. The telescopic cylinder 62 is disposed on the frame plate 100, and the output end of the telescopic cylinder 62 is connected to the wire guide wheel 61, so that the wire guide wheel 61 can move longitudinally.

[0058] The unwinding mechanism 5 is used to unwind the copper wire on the fixture 1-B. As described in the background art, the present invention involves winding a copper foil 1-D between two layers of copper wire. Therefore, the skeleton 1-C on the fixture 1-B already has the first layer of copper wire wound on it, while the second layer of copper wire is directly wound on the fixture 1-B. After the copper foil 1-D is wound on the first layer of copper wire, the second layer of copper wire wound on the fixture 1-B is unwound. The wire storage mechanism 6 serves to temporarily store the copper wire. The second layer of copper wire is pulled onto the wire guide wheel 61 by the pneumatic finger 52. The wire guide wheel 61 is lifted by the telescopic cylinder 62 to achieve the purpose of storage.

[0059] Furthermore, it also includes a storage mechanism, which is adjacent to the first platform 31. The storage mechanism includes a base plate 71, as well as multiple second baffles 72 and baffles 73. The second baffles 72 and baffles 73 are disposed on the surface of the base plate 71 and form a space for wrapping the copper foil 1-D. The copper foil 1-D is located in the aforementioned space. Specifically, the storage mechanism is used in conjunction with the adsorption mechanism 8 to remove the copper foil 1-D from the first platform 31.

[0060] like Figure 15-17 As shown, a method for wrapping copper foil:

[0061] S1, the spindle mechanism 2 moves to the periphery of the placement box 1-A, and the spindle mechanism 2 grabs the fixture 1-B in the placement box 1-A and moves to the end position of the track of the first platform 31;

[0062] S2, the copper foil 1-D is fed by the adsorption mechanism, and the copper foil 1-D is taken out from the storage mechanism. The adsorption mechanism moves above the first platform 31 and the second platform 34 and places the copper foil 1-D on the guide rails of the first platform 31 and the second platform 34. Then the adsorption mechanism is reset and leaves from directly above the first platform 31 and the second platform 34.

[0063] S3, the leveling cylinder 3503 drives the pressure head 3502 to move onto the copper foil 1-D via the connecting rod 3501, and the pressure head 3502 presses down the copper foil 1-D on the second platform 34;

[0064] S4, apply tape to copper foil 1-D. The second tape application mechanism 41 moves above copper foil 1-D and approaches one end of copper foil 1-D. The lower half of the rolling surface of the first pressure roller 414-A is covered with tape, with the adhesive side of the tape facing copper foil 1-D. The first pressure roller 414-A moves onto copper foil 1-D and presses the tape onto copper foil 1-D, thus bonding copper foil 1-D with the tape.

[0065] S5, the flipping cylinder 415-C drives the first baffle 415-A to flip, so that the first baffle 415-A separates from the first pressure roller 414-A, and the first tape applicator 41 moves on the copper foil 1-D in the direction of the above end until the tape is pressed by the first pressure roller 414-A onto both the skeleton 1-C and the copper foil 1-D, and then the cutter assembly 416 cuts the tape from the guide assembly 413;

[0066] S6, the first platform 31 located between the output end of the central push rod mechanism 32 and the output end of the main spindle mechanism 2 descends, and the second platform 34 formed by the end fitting is offset from the first platform 31. The second pressure roller 3302 moves onto the frame 1-C. Under the action of the main spindle mechanism 2 and the copper foil pressing cylinder 3301 in the copper foil pressing mechanism 33, the frame 1-C and the second pressure roller 3302 both move towards the second platform 34 until the end of the fixture 1-B and the top head 3201 of the central push rod mechanism 32 are opposite to each other. The driven rotating component pushes the top head 3201 to move towards the end of the fixture 1-B, so that the top head 3201 abuts against the end of the fixture 1-B. In addition, during the movement, the main spindle mechanism 2 drives the fixture 1-B to rotate, so the frame 1-C will also rotate.

[0067] S7, the second tape-applying mechanism 42 moves above the second platform 34 and presses the tape onto the copper foil 1-D corresponding to the second platform 34. The pressure head 3502 leaves the copper foil, and the second tape-applying mechanism 42 makes a lifting motion, lifting the copper foil 1-D from the track of the second platform 34 through the tape. Then, the main shaft mechanism 2 continues to rotate, winding all the remaining copper foil 1-D onto the skeleton 1-C. During winding, the second tape-applying mechanism 42 also moves towards the skeleton 1-C and breaks the tape near the skeleton 1-C.

[0068] S8, the pneumatic finger 52 clamps the second layer of wire on the fixture 1-B, and the main shaft mechanism 2 drives the fixture 1-B to rotate in the opposite direction of the second layer of wire winding, so that the second layer of wire is disengaged from the fixture 1-B.

[0069] S9, during the unwinding process, the second layer of wire dragged by the pneumatic finger 52 is attached to part of the rolling surface of the wire guide wheel 61. The telescopic cylinder 62 pulls the wire guide wheel 61 to lift it. At this time, the second layer of wire can be completely straightened, thereby achieving the wire storage effect.

[0070] S10, the main spindle mechanism 2 adjusts its position so that the copper foil 1-D on the skeleton 1-C corresponds to the second layer of wires, and rotates the fixture 1-B so that the second layer of wires is wound around the skeleton 1-C.

[0071] Figure 18 The diagram illustrates the application of the adhesive tape. In the first attached diagram on the left, line segment G represents the adhesive tape. As shown in the diagram, the sliding seat 416-B is extended, and the first baffle 415-A presses the tape onto the pressure plate 416-C, with the tape adhered to the first baffle 415-A. Next, the cutter 416-D cuts off the tape. Then, the sliding seat 416-B and the cutter 416-D return to their original positions. Finally, the first baffle 415-A pushes the tape to adhere to the first pressure roller 414-A.

[0072] The sliding seat 416-B previously pushed the tape to allow for the length of tape to be applied. Before applying the tape, the tape was pressed onto the copper foil 1-D by the first pressure roller 414-A. Then, the first baffle 415-A was driven to rotate and separate from the tape. The final figure shows the usage state of the tape moving on the copper foil 1-D.

[0073] It should be noted that the spindle mechanism 2, as an existing technology, has the function of moving forward, backward, left, and right; therefore, its specific structure will not be described in detail.

[0074] Similarly, the transport mechanism 1, the second linear moving component, and the first linear moving component 411 mentioned in the specification are also existing technologies, so the specific structure of their moving functions will not be described in detail.
