Technical Field

[0001] The invention relates to the field of copper foil winding, in particular to a copper foil wrapping device and a copper foil wrapping method. Background Art

[0002] Generally, the turns on the winding are all copper wires. In some special usage environments, it is necessary to wind a layer of copper foil between two layers of copper wires. 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 with the copper wire, the larger size brings the characteristic of not being easy to deform. Obviously, the traditional copper wire winding equipment cannot realize the winding of copper foil on the skeleton. In addition, it does not have a winding method for winding copper foil on the original copper wire. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a copper foil wrapping device capable of winding large-sized copper foil on a skeleton.

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

[0005] The spindle mechanism has an output end connected to one end of a fixture, and a frame is mounted on the fixture;

The tape applying mechanisms have moving tracks that move to both ends of the copper foil and are used to provide tape to both ends of the copper foil on the first platform.

[0008] Furthermore, the copper foil roll part 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. The flattening mechanism includes a connecting rod, a pressure head, and a leveling cylinder. The connecting rod is rotatably arranged on the second platform, the outer end of the connecting rod is connected to the pressure head, and the output end of the leveling cylinder is rotatably connected to the inner end of the connecting rod, and has a direction to rotate the outer end of the connecting rod toward the above-mentioned second platform track.

[0009] Furthermore, the central ejector mechanism includes an ejector head and a driven rotating assembly. The ejector head is connected to the movable end of the driven rotating assembly, and the end of the ejector head is conical.

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

[0011] Furthermore, the tape applying mechanism is used to apply the sticky surface of the tape to the end of the copper foil on the first platform. The tape applying mechanism includes a first linear moving component, and a tape pressing component, a flipping component, and a cutter component connected to the output end of the first linear moving component. The cutter component is located between the tape pressing component and the flipping component. The tape pressing component has a rolling portion for pressing the tape onto the copper foil. The flipping component has a rotatable first baffle. The first baffle has a length that jumps over the cutter component and is used to press the tape cut by the cutter component onto the rolling portion.

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

[0013] Furthermore, the pressing tape assembly includes a first pressing wheel, a mounting plate, a connecting piece, a spring, and a positioning plate. The connecting piece passes through the positioning plate and is connected to the mounting plate. The spring is sleeved on the connecting piece and is located between the positioning plate and the mounting plate. The first pressing wheel is connected to the mounting plate.

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

[0016] Furthermore, it also includes a material storage mechanism, which is adjacent to the first platform and includes a bottom plate, and a plurality of second baffles and baffle columns, which are arranged on the surface of the bottom plate and constitute a space for wrapping the copper foil.

[0017] Beneficial effects of the present invention:

[0018] 1. Firstly, the present invention realizes the winding of copper foil, mainly by means of a copper foil pressing mechanism and a main shaft mechanism, which applies pressure to the copper foil on the skeleton from the end position of the track, thereby bending the copper foil and forming a winding result on the skeleton.

[0019] 2. Secondly, the present invention uses a center push rod mechanism to stabilize the position of the jig. The jig is suspended in the air, and the center push rod mechanism is against the jig, which can resist the pressure applied by the copper foil pressing mechanism. For a high-precision spare part such as a jig, the use of the center push rod mechanism can effectively prevent the jig from being deformed.

[0020] 3. Furthermore, due to the relatively high hardness of the copper foil, the power source for bending the copper foil includes the power of the spindle to rotate the fixture and the power of the copper foil pressing mechanism. The spindle mechanism acts on the inner surface of the copper foil, and the copper foil pressing mechanism acts on the outer surface of the copper foil. This combination of inside and outside greatly reduces the difficulty of bending the copper foil. Moreover, there is no gap between the copper foils, and similarly, there is no gap between the copper foils and the frame. In addition, this implementation method makes the surface of the copper foil smoother.

[0021] 4. The mechanism, setting position, and moving track selected in the present invention are all special choices made to be able to wind copper foil on the frame with the first layer of wire wound around it, so as to meet the requirements of winding copper foil on the wire.

[0040] Description of Figure Numbers: DETAILED DESCRIPTION

[0041] A copper foil device, such as Figure 1-2 As shown, it is characterized in that it includes the following structures arranged on the frame plate 100:

[0042] The transport mechanism 1 has a placement box 1-A at the output end thereof for placing a jig 1-B with a skeleton 1-C.

[0043] The spindle mechanism 2, whose output end is connected to one end of the fixture 1-B, and the fixture 1-B is covered with a frame 1-C;

[0044] like Figure 5As shown, the copper foil roll part 3 is used to wind the copper foil 1-D on the skeleton 1-C on the output end of the spindle mechanism 2, and the copper foil roll part 3 includes a first platform 31, a center push rod mechanism 32, a copper foil pressing mechanism 33, and a second platform 34. The output shaft of the center push rod mechanism 32 and the fixture 1-B on the spindle mechanism 2 are opposite to each other, and the center push rod mechanism 32 has a track moving toward the fixture 1-B, and its output end is used to abut the other end of the fixture 1-B. The first platform 31 is located between the output end of the center push rod mechanism 32 and the output end of the spindle mechanism 2, and the second platform 34 and the first platform 31 are formed by end-to-end bonding, and the first platform 31 has a movable track that can be raised and lowered, and the first platform 31 and the second platform 34 have tracks that are adapted to the size of the copper foil 1-D, and 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;

[0045] The tape applying part comprises a group of tape applying mechanisms (41, 42), the tape applying mechanisms (41, 42) are distributed on two side areas of the first platform 31, and the tape applying mechanisms (41, 42) have moving tracks that move to the two ends of the copper foil 1-D, and are used to provide tape to the two ends of the copper foil 1-D on the first platform 31.

[0046] First, the present invention realizes the winding of the copper foil 1-D, mainly by using the copper foil pressing mechanism 33 and the main shaft mechanism 2, applying pressure to the copper foil 1-D on the skeleton 1-C from the end position of the track, thereby allowing the copper foil 1-D to bend and form a winding result on the skeleton 1-C.

[0047] Secondly, the present invention uses the center push rod mechanism 32 to stabilize the position of the jig 1-B. The jig 1-B is suspended in the air. The center push rod mechanism 32 is against the jig 1-B and can resist the pressure applied by the copper foil pressing mechanism 33. For a relatively high-precision component such as the jig 1-B, the use of the center push rod mechanism 32 can effectively prevent the jig 1-B from being deformed.

[0048] Furthermore, since the hardness of the copper foil 1-D is relatively high, the source of power for bending the copper foil 1-D includes the power of the spindle mechanism 32 to rotate the jig 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 outside of the copper foil 1-D. This combination of inside and outside 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.

[0049] The mechanism, setting position, and activity trajectory selected by the present invention are all special choices made to be able to wind copper foil 1-D on the skeleton 1-C wound with the first layer of wires, meeting the requirements of winding copper foil 1-D on the first layer of wires.

[0050] like Figure 6 As shown, further, the copper foil roll portion 3 also includes a flattening mechanism 35 for pre-pressing the copper foil 1-D on the track of the second platform 34, and the flattening mechanism 35 is distributed in the lateral 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 arranged on the second platform 34, and 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 for rotating the outer end of the connecting rod 3501 toward 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 portion 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, there is a There is a partial warping situation. When winding on the skeleton 1-C, there are gaps between the layers of copper foil 1-D. The pressure head 3502 applies pressure to the copper foil 1-D, and the leveling effect on the copper foil 1-D can reduce the gaps and improve the stability of the winding structure. In addition, after the copper foil 1-D is wound, the copper foil 1-D needs to be wound again. The outermost layer of the copper foil 1-D on the winding is the part of the original copper foil 1-D corresponding to the second platform 34. After leveling, the copper foil 1-D of this part is flat. At this time, there will be no unevenness between each circle of copper wire in each layer of copper wire, and there will be no interference with the magnet during subsequent assembly (the choice of 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).

[0051] like Figure 7 As shown, further, the central ejector mechanism 32 includes a ejector head 3201 and a driven rotating assembly. The ejector head 3201 is connected to the movable end of the driven rotating assembly, and the end of the ejector head 3201 is conical; the ejector head 3201 provides additional support to prevent the fixture 1-B from sagging or deflecting due to gravity or inertia during rotation; another advantage is that it can effectively reduce the vibration generated by the fixture 1-B during rotation, thereby improving the overall stability and reliability of the copper foil 1-D.

[0052] like Figure 8As shown, further, the copper foil pressing mechanism 33 includes a copper foil pressing cylinder 3301, a second pressing wheel 3302 and a sliding assembly 3303. The output end of the copper foil pressing cylinder 3301 is connected to the second pressing wheel 3302 through the sliding assembly 3303, and the copper foil pressing cylinder 3301 has a direction to push the second pressing wheel 3302 to the above-mentioned end position; since the copper foil 1-D is not easy to deform, and the spindle mechanism 2 makes the copper foil 1-D form a preliminary arc contour, there is a situation where the copper foil 1-D and the skeleton 1-C are not fitted. At this time, the second pressing wheel 3302 applies pressure to the outside of the copper foil 1-D, so that the copper foil 1-D fits with each other, and can also make the copper foil 1-D fit with the skeleton 1-C.

[0053] like Figure 9-12 As shown, further, the adhesive tape mechanism 41 is used to stick the sticky surface of the tape on the end of the copper foil 1-D on the first platform 31, and the first adhesive tape mechanism 41 includes a first linear moving component 411. In this embodiment, the first linear moving component 411 is connected to the guide component 413, the adhesive tape pressing component 414, the flip component 415, and the cutter component 416 through the main board 412. The cutter component 416 is located between the adhesive tape pressing component 414 and the flip component 415. The guide component 413 is adjacent to the side area of ​​the flip component 415. The guide component 413 has a direction of sending the tape to the flip component 415, and the adhesive tape pressing component 414 is connected to the flip component 415. The tape assembly 414 has a rolling portion for pressing the tape onto the copper foil 1-D, and the flip assembly 415 has a first baffle 4103 rotatably connected to the main board 412. The first baffle 4103 has a length that jumps over the cutter assembly 416, and is used to press the tape cut off by the cutter assembly 416 onto the rolling portion; the above scheme is to enable the tape to be smoothly attached to the rolling portion, the cutter assembly 416 is located between the flip assembly 415 and the tape pressing assembly 414, the first baffle 415-A in the flip assembly 415, and the rotatable action, so that the cut tape can be pushed onto the rolling portion, and the rolling portion can press the tape onto the copper foil 1-D.

[0054] The guide assembly 413 is composed of a plurality of guide rollers 413 -A and a reel 413 -B.

[0055] 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.

First, it provides support. The sliding seat 416-B can move on the active track of the first baffle 415-A. The sticky surface of the tape is facing the outer end surface of the first baffle 415-A. At this time, the first baffle 415-A pushes the tape to move onto the sliding seat 416-B, and after arriving at the sliding seat 416-B, the sticky surface is connected to the outer end surface of the first baffle 415-A, and the tape is also adhered 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, and finally pushing the tape to the rolling part, thereby determining the contact relationship between the tape and the rolling part.

[0056] like Fig.12 As shown, further, the tape pressing assembly 414 includes a first pressure wheel 414-A, a mounting plate 414-E, a connecting piece 414-C, a spring 414-B, and a positioning plate 414-D. The connecting piece 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 connecting piece 414-C and is located between the positioning plate 414-D and the mounting plate 414-E. The first pressure wheel 414-A is connected to the mounting plate 414-E; in this embodiment, the mounting plate 414-E is connected to the matching main board 412 of the slider through a slide rail. When the first pressure wheel 414-A is pressed against the tape, the spring 414-B will be deformed. After the pressure on the first pressure wheel 414-A ends, the spring 414-B is reset.

[0057] Furthermore, if Fig.13As shown, the flip assembly 415 also includes a swing arm 415-B, a flip cylinder 415-C, a bearing seat 415-D, and a connecting shaft 415-E located on the back of the main board 412. The 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 flip cylinder 415-C has a pushing direction to move toward the swing arm 415-B. The output end of the flip cylinder 415-C is connected to the bearing seat 415-D. A bearing is provided on the bearing seat 415-D. 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 actively driven. In addition, using a bearing to push the swing arm 415-B can reduce wear on the swing arm 415-B.

[0058] like Figure 3 , 5 , 9, and 14, further, it also 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, and the wire unwinding mechanism 5 includes a rotary cylinder 51 arranged on the output end of the first linear moving component 411, and a pneumatic finger 52 and a pneumatic scissors 53 arranged on the output end of the rotary cylinder 51; located above the spindle mechanism 2, the wire storage mechanism 6 includes a wire passing wheel 61 and a telescopic cylinder 62, the telescopic cylinder 62 is arranged on the frame plate 100, and the output end of the telescopic cylinder 62 is connected to the wire passing wheel 61, so that the wire passing wheel 61 can move longitudinally;

[0059] The unwinding mechanism 5 is used to unwind the copper wire on the jig 1-B. As described in the background technology, the present invention winds a layer of copper foil 1-D between two layers of copper wire. Therefore, the skeleton 1-C on the jig 1-B has been wound with the first layer of copper wire, and the second layer of copper wire is directly wound on the jig 1-B. After the winding of the copper foil 1-D on the first layer of copper wire is completed, the second layer of copper wire wound on the jig 1-B is unwound; the wire storage mechanism 6 plays an effect of temporarily storing the copper wire. The second layer of copper wire is pulled onto the wire wheel 61 by the pneumatic finger 52, and the wire wheel 61 is lifted by the telescopic cylinder 62 to achieve the purpose of storage.

[0060] Furthermore, it also includes a storage mechanism, which is adjacent to the first platform 31. The storage mechanism includes a bottom plate 71, and a plurality of second baffles 72 and baffle columns 73. The second baffles 72 and baffle columns 73 are arranged on the surface of the bottom plate 71, and constitute a space for wrapping the copper foil 1-D; the copper foil 1-D is located in the above-mentioned space; specifically, the storage mechanism is used in conjunction with the adsorption mechanism, and the copper foil 1-D is taken out onto the first platform 31 through the adsorption mechanism 8.

[0061] like Figure 15-17 As shown, a copper foil wrapping method:

[0062] 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;

[0063] S2, the adsorption mechanism is used to load the copper foil 1-D, and the copper foil 1-D is taken out from the storage mechanism. The adsorption mechanism moves to the top of the first platform 31 and the second platform 34, and the copper foil 1-D is placed on the guide rails of the first platform 31 and the second platform 34. Then the adsorption mechanism is reset and leaves from the top of the first platform 31 and the second platform 34.

[0064] S3, the leveling cylinder 3503 drives the pressing head 3502 to move onto the copper foil 1-D through the connecting rod 3501, and the pressing head 3502 presses the copper foil 1-D on the second platform 34;

[0065] S4, the copper foil 1-D is taped, the second taping mechanism 41 moves to the top of the copper foil 1-D and approaches one end of the copper foil 1-D, the lower half of the rolling surface of the first pressing wheel 414-A is taped, the sticky side of the tape faces the copper foil 1-D, the first pressing wheel 414-A moves onto the copper foil 1-D, presses the tape onto the copper foil 1-D, and the copper foil 1-D is bonded to the tape;

[0066] S5, the flip cylinder 415-C drives the first baffle 415-A to flip, so that the first baffle 415-A is separated from the first pressing wheel 414-A, and the first tape sticking mechanism 41 moves on the copper foil 1-D toward the above-mentioned one end direction until the tape is pressed by the first pressing wheel 414-A on the frame 1-C and the copper foil 1-D at the same time, and then the cutter assembly 416 disconnects the above-mentioned tape from the guide assembly 413;

[0067] S6, the first platform 31 located between the output end of the center push rod mechanism 32 and the output end of the spindle mechanism 2 descends, and the second platform 34 formed by the end fitting is in an offset state with the first platform 31, and the second pressing wheel 3302 moves toward the skeleton 1-C, and under the action of the spindle mechanism 2 and the copper foil pressing cylinder 3301 in the copper foil pressing mechanism 33, the skeleton 1-C and the second pressing wheel 3302 both move toward the second platform 34 until the end of the fixture 1-B and the top head 3201 of the center push rod mechanism 32 are opposite to each other, and the driven rotating component pushes the top head 3201 toward the end of the fixture 1-B, so that the top head 3201 and the end of the fixture 1-B are against each other. In addition, during the movement of the spindle mechanism 2, it drives the fixture 1-B to rotate, so the skeleton 1-C will also rotate.

[0068] S7, the second tape-applying mechanism 42 moves to the top of the second platform 34, and presses the tape on 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 performs a lifting movement to lift the copper foil 1-D from the track of the second platform 34 through the tape. Then, the spindle mechanism 2 continues to rotate and winds the remaining copper foil 1-D around the skeleton 1-C. During the winding process, the second tape-applying mechanism 42 will also move toward the skeleton 1-C and disconnect the tape at a position close to the skeleton 1-C.

[0069] S8, the pneumatic finger 52 clamps the second layer of wires on the jig 1-B, and the spindle mechanism 2 drives the jig 1-B to rotate in the opposite direction of the winding of the second layer of wires, so that the second layer of wires is detached from the jig 1-B;

At this time, the second layer of wire can be completely straightened, thereby achieving the wire storage effect.

[0071] S10, the spindle mechanism 2 adjusts its own 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.

[0073] The sliding seat 416-C previously pushed the tape in order to reserve a length for the tape to be pasted.
