Description

Technical Field

[0001] The utility model relates to the field of winding of copper foils, and particularly to a wire winding device for winding sheet copper foils. Background Art

[0002] In the wire winding device of a winding, the processes of attaching copper foils and winding copper wires or conductors are involved. For example, in the device with the application number CN202211318224.8 and the name of an automatic copper foil attaching and PIN foot winding device, this device uses rolls of tape to wind the skeleton, and the tape roll contains copper foils and copper wires.

[0003] Since the copper wire or conductor is welded to the copper foil, there are tin points on the copper foil, and the shape of the tin points is limited by the use condition of the welding nozzle, resulting in the shape of some tin points being approximately spiky. After the tape roll winds the skeleton, there is a risk that the tin points pierce the tape roll.

[0004] The current treatment method is to attach a new tape that can resist being pierced by the tin points on these tin points. During winding, the problem of the tin points piercing the tape can be solved. However, during the process of attaching the new tape, the tape roll needs to be cut into many segments. Otherwise, due to the overall arching condition of the tape roll, the efficiency of attaching the new tape is affected.

[0005] In addition, after attaching the new tape roll, it needs to be transferred to another tape line, and with the adhesion of the other tape line, the tape roll wound on the skeleton is fixed.

[0006] However, the existing devices for attaching copper foils and winding copper wires or conductors cannot apply this sheared tape and lack the adaptability for using it. Content of the Utility Model

[0007] To solve the above problems, the utility model provides a wire winding device for winding sheet copper foils. The feeding mechanism thereof provides storage and transfer of the sheared tape, so that it can be integrated into the process of winding on the skeleton.

[0008] To achieve the above object, the technical solution adopted by the present utility model is as follows: A wire winding device for winding sheet copper foil has a tape pulling mechanism for taking out a high-temperature resistant tape. It is characterized in that it further includes a feeding mechanism for storing and positioning the copper foil tape and transferring the copper foil tape. The feeding mechanism includes a copper foil tape positioning fixture and a copper foil tape sucking component. The copper foil tape sucking component is arranged on a guide pin mechanism. Through a linear movement component in the guide pin mechanism, the copper foil tape in the copper foil tape positioning fixture is transferred onto the high-temperature resistant tape. The copper foil tape positioning fixture is formed by enclosing a stop post and a baffle plate arranged on a base. The copper foil tape is located in a positioning bin formed by the combination of the stop post and the baffle plate. Among them, there are multiple baffle plates and stop posts. There are gaps reserved between the baffle plates and the stop posts, and between the stop posts and the stop posts.

[0009] Further, it further includes a copper foil tape correction plate connected to the base. The copper foil tape correction plate is provided with a correction groove adapted to the copper foil tape, and evacuation holes are arranged in the correction groove.

[0010] Further, the feeding mechanism further includes an optical fiber sensor and a rotating device. The rotating device is arranged on the guide pin mechanism, and the copper foil tape sucking component is arranged on the rotating end of the rotating device. The optical fiber sensor is arranged on the base, and the detection range of the optical fiber sensor overlaps with a partial path where the copper foil tape is transferred.

[0011] Further, it further includes a wire straightening mechanism for straightening the wire. The wire straightening mechanism includes a linear movement mechanism and a pneumatic finger. A wire straightening clip is arranged on the inner side of the clamping end of the pneumatic finger. The linear movement mechanism drives the pneumatic finger to move along a specified movement track from one end of the wire to the other end to straighten the wire.

[0012] Further, there are at least two clamping ends on the pneumatic finger, and the wire straightening clips are staggered from each other. The side surfaces of the wire straightening clips adjacent to the wire are inverted cones. In the clamped state, the deepest parts of the wire straightening clips on both sides of the wire form a clamping posture for the wire.

[0013] Further, it further includes a positioning plate arranged on the side of the pneumatic finger, and the top of the positioning plate is a V-shaped groove.

[0014] Further, the copper foil tape sucking component is a suction nozzle.

[0015] The beneficial effects of the present utility model:

[0016] The main purpose of the present utility model is to establish the relationship that the sheet copper foil tape can be used on the wire winding device. The copper foil tape positioning fixture in the present utility model provides the storage and positioning of the sheet copper foil tape. In particular, the setting method of reserving gaps between the baffle plate and the stop post that form the positioning bin meets the condition of avoiding the wire. Combined with the use of the copper foil tape sucking component, the transfer of the sheet copper foil tape onto the high-temperature resistant tape is thus realized.

[0033] As Figure 1As shown Figure 1 shows a partial structure of the winding device for winding sheet copper foil of the present utility model. In this winding device, there are included Figures 2 - 4 as shown in the tape pulling mechanism 1, the feeding mechanism 2 for providing the copper foil tape 7 to the tape pulling mechanism 1, the main shaft mechanism 3 for driving the rotation and movement of the skeleton, the wire arranging mechanism 4 for straightening the scattered wires 8, and the guide pin mechanism 6 for winding the wire 8 around the skeleton.

[0034] The tape pulling mechanism 1 is used to pull out the first tape 100 to the vicinity of the skeleton 5 (as Figure 5 shown). During winding, the tape pulling mechanism 1 moves below the main shaft mechanism 3 and cooperates with the main shaft mechanism 3 to wind the first tape 100 around the skeleton 5.

[0035] As Figures 6 - 8 shown, the tape pulling mechanism 1 includes a main board 1a, and a tape loop 1b, a shearing mechanism 1p, a traction mechanism, and a copper foil tape supporting mechanism provided on the side surface of the main board 1a. A plurality of guiding rubber wheels 1c are also provided on the side surface of the main board 1a. The guiding rubber wheels 1c play a role of guiding and transporting, guiding the first tape 100 to the above-mentioned mechanisms, and connecting the transmission of the first tape 100 between two mechanisms;

[0036] From Figure 6 it can be seen that the tape loop 1b, the shearing mechanism 1p, the copper foil tape supporting mechanism, and the traction mechanism are arranged in sequence from right to left. Before winding, two conditions need to be met. First, the first tape 100 is pulled to ensure that the first tape 100 has enough length to contact the skeleton 5, and when the skeleton 5 rotates, the first tape 100 is continuously pulled out. Second, the copper foil tape 7 needs to be attached to the first tape 100.

[0037] The copper foil tape supporting mechanism includes a copper foil tape supporting table 1d and a copper foil tape supporting cylinder 1e. Under the longitudinal contraction of the copper foil tape supporting cylinder 1e, the position of the copper foil tape supporting table 1d is below the traction mechanism, and its purpose is to let the copper foil tape supporting table 1d withdraw from the moving path of the first tape 100 and avoid the movement of the traction mechanism in the moving path of the first tape 100 next;

[0038] The first tape 100, which is a coiled material, is sleeved on the tape loop 1b and is pulled to the guiding rubber wheel 1c adjacent to the shearing mechanism 1p (see Figure 9As shown, the head of the first tape 100 is suspended outside the guiding rubber wheel 1c under the support of the guiding rubber wheel 1c. The traction mechanism moves along the moving path of the first tape 100 towards the guiding rubber wheel 1c. After clamping the head of the first tape 100, it returns to its original position. The reset of the traction mechanism will pull the first tape 100 to move on the preset path, and this pulling action also enables the first tape 100 to have sufficient wrapping length.

[0039] After the traction of the first tape 100 is completed, the position of the copper foil tape support table 1d returns. This return positions to support the first tape 100 and provides a supporting force to the first tape 100. The feeding mechanism 2 then transfers the copper foil tape 7 onto the first tape 100. By using the copper foil tape support table 1d, the copper foil tape 7 is pressed onto the first tape 100.

[0040] After the above actions, the shearing mechanism 1p cuts the first tape 100, and the traction mechanism releases the clamping of the head of the first tape 100. The head of the first tape 100 falls to the lower pressing wheel 1f. A first air cylinder 1g for pushing the pressing wheel 1f to move longitudinally is provided on the side of the main board 1a. The first air cylinder 1g pushes the pressing wheel 1f, and through the pressing wheel 1f, the first tape 100 is lifted, and the head of the first tape 100 is lifted to a position in contact with the skeleton 5. The main shaft mechanism 3 rotates, driving the skeleton 5 to rotate, and the first tape 100 is wound around the skeleton 5.

[0041] The traction mechanism is composed of a first pneumatic finger 1h, a driving motor 1i, a belt 1m, a synchronous pulley 1n, a slider 1o, a slide rail 1j, and a clamping block 1k. The clamping block 1k is controlled by the first pneumatic finger 1h to achieve the closing or separation between the clamping blocks 1k.

[0042] Since the components of this traction mechanism are prior art, the connection relationships of the other components will not be elaborated further.

[0043] The feeding mechanism 2 in the present utility model has two functions: storing and positioning the copper foil tape 7 and transferring the copper foil tape 7. The feeding mechanism 2 includes a copper foil tape positioning fixture 21 and a copper foil tape suction assembly 22. The copper foil tape suction assembly 22 is arranged on the guide pin mechanism 6 (as Figure 3 shown). This makes the scheme for transferring the copper foil tape 7 not complex in most cases. It simply borrows the first linear movement component 61 in the guide pin mechanism 6 (as Figure 1 shown) to transfer the copper foil tape 7 from the copper foil tape positioning fixture 21 to the first tape 100 through movement in different dimensions.

[0044] From Figure 11It can be known that the copper foil tape positioning fixture 21 for storing the copper foil tape is formed by enclosing a baffle 21a and a retaining post 21b on a base 21c. The copper foil tape 7 is arranged in the positioning bin formed by the baffle 21a and the retaining post 21b. As one side of the positioning bin, the retaining posts 21b not only have gaps reserved between them, but also have a certain space reserved between them and the baffle 21a. The arrangement of the retaining posts 21b is to reduce the contact area with the copper foil tape 7, so that the copper foil tape 7 can enter the positioning bin more smoothly. The space reserved with the baffle 21a is to avoid the wire 8 on the copper foil tape 7.

[0045] The copper foil tapes 7 are stacked in piles in the positioning bin.

[0046] Since only one wire 8 is welded on a single copper foil tape 7, and in the placement method of the copper foil tapes 7 in the positioning bin, only the side with the solder joint is facing the copper foil tape suction assembly 22, it is inevitable that the wire 8 will face in the opposite direction (as Figure 10 shown). For the main shaft mechanism 3, more strokes and actions need to be performed to complete the winding of a single skeleton 5.

[0047] To solve the above problems, the feeding mechanism 2 further includes an optical fiber sensor (not shown in the figure) and a rotating device 21d. Among them, the rotating device 21d is arranged on the guide pin mechanism 6 (as Figure 3 shown), and the copper foil tape suction assembly 22 is arranged on the rotating end of the rotating device 21d. In this embodiment, there is one optical fiber sensor, and the fixed seat 21e of the optical fiber sensor is arranged at the end of the copper foil tape correction plate 21f, and the optical fiber sensor is arranged on the fixed seat 21e (as Figure 11 shown). The optical fiber sensor is used to detect the wire 8 facing a single direction. By detecting whether the wire 8 passes, it controls whether the rotating device 21d rotates. The principle of its use is illustrated as follows: When the optical fiber sensor does not detect the wire 8, the upper computer controls the rotating device 21d to rotate 180°. After the copper foil tape 7 that rotates drivenly rotates, the position of the wire 8 coincides within the detection range of the optical fiber sensor. Thus, the upper computer judges that the position of the wire 8 has been accurately adjusted according to the feedback signal of the optical fiber sensor.

[0048] In addition, the copper foil is very thin. In some embodiments, the thickness of the copper foil is 35um (1 ounce), and it is easily deformed by external forces. As described above, the copper foil tape 7 is in a disk shape after being produced. After shearing, it is difficult to avoid the deformation phenomenon of arching in some areas. Therefore, a copper foil tape correction plate 21f is also needed to correct it. The copper foil tape correction plate 21f is provided with a correction groove 21f' (as Figure 12As shown, a vacuum hole 21f-1 is provided in the calibration groove 21f'. After the copper foil tape 7 is placed in the calibration groove 21f', these arched areas are attached to the bottom surface of the calibration groove 21f' by means of vacuum pumping, reshaping the shape of the copper foil tape 7.

[0049] The above-mentioned copper foil tape calibration plate 21f further has a support plate 21f-2 extending to the base 21c, and the support plate 21f-2 is connected to the base 21c.

[0050] The copper foil tape suction assembly 22 is a suction nozzle of the prior art. In this embodiment, there are two suction nozzles.

[0051] The present utility model further includes a wire straightening mechanism 4. The wire straightening mechanism 4 is used to straighten the wire 8 to ensure that the subsequent needle guiding mechanism 6 can smoothly clamp the wire 8. The wire straightening mechanism 4 includes a second linear movement mechanism 41 and a second pneumatic finger 42. Inside the clamping end of the second pneumatic finger 42, there is a wire straightening clip 43 capable of clamping the wire 8. The above-mentioned second linear movement mechanism 41 can make the second pneumatic finger 42 move along a specified movement trajectory from one end to the other end of the above-mentioned wire 8 to straighten the above-mentioned wire 8.

[0052] The second linear movement mechanism 41 is of the prior art. Therefore, its structure will not be described in detail.

[0053] From Figures 14 - 15 it can be seen that the second pneumatic finger 42 has two clamping ends. The wire straightening clips 43 on the two clamping ends are staggered from each other, and the side surface of the wire straightening clip 43 adjacent to the wire is inverted conical. In the clamping state, the deepest part 43' of the side surfaces of the two wire straightening clips 43 clamps the wire. In other words, this structure presses different areas of the wire 8 from different directions, and the formed constraint effect can improve the tortuosity of the wire 8 when dragging the second pneumatic finger 42 to achieve the purpose of wire straightening. It is not difficult to see that this means of clamping the wire 8 is guided by the side surface of the wire straightening clip 43 and will form a clamping result after the guiding ends. Therefore, this wire straightening structure will not cause any damage to the wire 8.

[0054] As Figure 13 shown, multiple wire straightening clips 43 can be provided on the clamping end of the second pneumatic finger 42. In the embodiment, on one of the clamping ends of the second pneumatic finger 42, there are two wire straightening clips 43, and there is a spaced space between these two wire straightening clips 43.

[0055] On the side surface of the second pneumatic finger 42, there is also a positioning plate 44. The top surface of the positioning plate 44 is a V-shaped groove 44'. In the clamping state, the bottom of the V-shaped groove 44' corresponds to the deepest part 43' of the inner side surface of the wire straightening clip 43 (as Figures 14 - 16Before clamping the wire 8, the second pneumatic finger 42 is open, and the opening and closing range of the second pneumatic finger 42 is larger than the opening and closing range of the V shape. Under the action of the second linear moving mechanism 41, the wire 8 is first contacted through the V-shaped groove 44' to guide the wire 8 to ensure that the position of the wire 8 is located at the bottom of the V-shaped groove 44', and then the wire drawing clamp 43 performs the wire drawing action;

[0056] The purpose is to guide the position of the wire 8 in the movable path of the wire clamp 43. As mentioned above, the opening and closing range of the second pneumatic finger 42 is larger than the opening and closing range of the V shape. When the wire 8 is not in the movable path of the wire clamp 43, there is a situation where the wire clamp 43 cannot clamp the wire 8.

[0057] The above implementation modes are merely descriptions of the preferred implementation modes of the present invention, and are not intended to 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 and technical personnel in the field shall fall within the protection scope determined by the claims of the present invention.
