Description

Technical Field

[0001] This utility model relates to the field of wrapping adhesive tape, and more particularly to a device for folding adhesive tape. Background Technology

[0002] A conventional winding mainly consists of two parts: a bobbin and copper wires. There are at least two copper wires, which are wound onto the bobbin in a double-row parallel winding manner.

[0003] After the copper wire is fully wound around the skeleton, wrap multiple layers of the first adhesive tape around the copper wire in the direction of the rotating arrow, as shown. Figure 1 As shown in the figure, the multi-ended line is a schematic diagram of a single copper wire after being wrapped with tape, and the end of the copper wire is pulled out (the "wrapped" refers to the number of layers of copper wire stacked by continuous winding being equal to or higher than the height of the protrusion T). After the end of the wire is pulled out, it is connected to other devices.

[0004] Figure 1 The horizontal arrow in the middle indicates the direction of the copper wire pulling, which points towards the side edge of the tape. Therefore, the outermost layer of copper wire (which contains multiple layers of copper wire) that is closest to the pulling direction will be pulled directly out of the frame. This results in fewer turns in the winding, which in turn affects the electrical performance of the entire product.

[0005] The current solution is to fold and glue the two copper wires together near the ends using a second layer of tape (e.g., Figure 2-3 As shown), then wrap it around the skeleton; after the copper wire is fully wrapped, use the first tape to wrap around the second tape and the two copper wires. In this way, when the wire end is pulled, the entire loop of copper wire corresponding to the wire end will not be pulled out. However, at present, there is a lack of equipment that can fold and bond the tape on these copper wires. Utility Model Content

[0006] To solve the above problems, this utility model provides a device for folding tape, which can provide a positioning effect for folding and bonding multiple copper wires.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A device for folding tape, characterized in that it consists of a tape feeding mechanism and a folding mechanism, wherein a pair of folded parts included in the folding mechanism form a space inside that is adapted to the outer periphery of a copper wire after being spliced ​​together, and a wire passage for the copper wire to enter is formed by the spacing between them.

[0009] Guided by the tape feeding mechanism, the tape is positioned on the path of the copper wire moving towards the wire opening, so that the tape contacts the copper wire in the tangential direction. The tape is pushed into the space by the copper wire and is folded by the constraint of the inner wall of the space.

[0010] Furthermore, it also includes a base plate that provides a fixed position for the folding mechanism, the groove being an arc-shaped groove, the axis of which is perpendicular to the base plate.

[0011] Furthermore, the tape feeding mechanism is composed of a tape ring, multiple guide rollers, and a tape clamping mechanism. The rotating shaft on the side of the tape ring is connected to the base plate. The base plate is provided with a number of roller shafts corresponding to the guide rollers, so that the guide rollers rotate relative to the base plate after being fitted onto the roller shafts. The tape clamping mechanism includes a second pneumatic finger, a tape clamp, and a first linear movement component. The first linear movement component is disposed on the base plate, and the second pneumatic finger is fixed on the output end of the first linear movement component with one side of the clamp adjacent to the base plate.

[0012] Furthermore, the surfaces of the tape clamps facing each other are provided with mutually cooperating grooves and protrusions. When clamped, the tape is pushed into the grooves by the protrusions.

[0013] Furthermore, the tape feeding mechanism also includes a counter-tension cylinder and a counter-tension mounting block. The counter-tension cylinder is mounted on a base plate, which has an opening structure. The opening structure has a length for the counter-tension mounting block to move. The counter-tension mounting block is mounted in the opening structure and is connected to the piston rod of the counter-tension cylinder.

[0014] Furthermore, it also includes a cutting mechanism, which comprises a cutter, a pressing block, a first slide rod, a second slide rod, a guide seat, a cutting cylinder, a pressing tape cylinder, and a fixing block. The cutter is positioned between the rubber wheel shaft and the folded part. The guide seat is mounted on the base plate. The first slide rod and the second slide rod pass through the guide seat and are slidably connected to it. The cutting cylinder and the pressing tape cylinder are mounted on the base plate and are connected to the cutter and the pressing block respectively through the first slide rod and the second slide rod. The L-shape of the fixing block is formed by connecting the first connecting part and the second connecting part. The upper surface of the first connecting block is provided with a guide opening adapted to the width of the tape. The guide opening corresponds vertically to the pressing block. The first connecting part is fixed to the base plate through the second connecting part. In addition, the guide opening also corresponds horizontally to the tape clamp.

[0015] Furthermore, a second linear moving component can be provided, which is mounted on the base plate, and the folding mechanism is mounted on the second linear moving component.

[0016] The beneficial effects of this utility model are:

[0017] This utility model provides two parts to achieve different effects: a tape feeding mechanism and a folding mechanism. The tape feeding mechanism provides a guiding function, positioning the tape on the path through which the copper wire enters the folded section. This guidance also ensures that the contact between the tape and the copper wire is tangential to the copper wire. Therefore, combined with the space in the folding mechanism that fits the circumference of the copper wire, the copper wire pushes the tape into the aforementioned space. The tape is pressed tightly against the copper wire by the inner wall of the aforementioned space, and the beginning and end portions of the tape corresponding to the wire passage are also bonded together by the splicing between the folded sections. Thus, the purpose of wrapping multiple copper wires together by folding the tape is achieved. Attached Figure Description

[0030] Figure 1 This invention illustrates a device for folding tape X. In this embodiment, the device is used to fold tape X on multiple copper wires Y (e.g., Figure 1-3As shown in the figure, with the help of tape X, when the end of the first copper wire Y is pulled out, the remaining part of the copper wire Y belonging to the end is constrained by the adjacent second copper wire K, and thus fixed to the skeleton.

[0031] like Figure 4 As shown, this utility model includes a base plate 3 that provides a fixed position, and a tape feeding mechanism and a folding mechanism disposed on the same surface of the base plate 3.

[0032] The folding mechanism includes a pair of folding parts 1 and a first pneumatic finger 2. The grippers on the first pneumatic finger 2 are connected to the folding parts 1, controlling the folding parts 1 to move closer or further apart. The first pneumatic finger 2 is fixed to the base plate 3 with one side 21 of its gripper adjacent to the base plate 3 (e.g., ...). Figure 7 As shown), the surfaces of the folded portions 1 that face each other can be provided with an arc-shaped groove 1b (such as) where the axis 1a is perpendicular to the base plate 3. Figure 6 As shown), after the two folded parts 1 are spliced ​​together, the arc groove 1b forms a space that fits the outer periphery of the copper wire Y. In other words, in the space mentioned above, the axis 1a of the copper wire Y coincides with the axis of the arc groove 1b.

[0033] The tape feeding mechanism provides a guiding function, firstly ensuring that the tape X falls onto the path of the copper wire Y as it moves into the folding mechanism (e.g., Figure 8 As shown, direction U is the direction of movement of copper wire Y), and it passes through the copper wire Y to move into the folding mechanism. Secondly, it ensures that the tape X is in contact with the copper wire Y, which is tangential to the outer circumference of the copper wire Y.

[0034] Therefore, it is not difficult to conclude that the two sides X1 of the adjacent adhesive surface Z on the tape X are relatively perpendicular to the base plate 3.

[0035] The tape feeding mechanism is composed of a tape ring 100, multiple guide rollers 101, and a tape clamping mechanism. The rotating shaft on the side of the tape ring 100 is connected to the base plate 3. When the tape X is dragged, the tape ring 100 rotates.

[0036] like Figure 9 As shown, the base plate 3 is provided with a number of rubber wheel shafts 102 corresponding to the guide rubber wheels 101. The rotation axis of the rubber wheel shaft 102 is configured to be perpendicular to the side of the base plate 3, so that after the guide rubber wheel 101 is sleeved on the rubber wheel shaft 102, it rotates relative to the base plate 3.

[0037] The tape clamping mechanism includes a second pneumatic finger 200, a tape clamp 202, and a first linear movement component 201. The first linear movement component 201 is mounted on the base plate 3. The second pneumatic finger 200 is fixed to the output end of the first linear movement component 201 with one side of the clamp adjacent to the base plate 3. This ensures that after the tape clamp 202 is installed on the clamp, it moves the tape X by clamping a pair of opposing surfaces of the tape X.

[0038] like Figure 8 As shown above, this utility model guides the tape X onto the path where the copper wire Y enters the folded portion 1, maintaining a tangential relationship between the tape X and the copper wire Y. When the copper wire Y is pushed into the tape X along direction U, the tape X is squeezed into the space between the folded portions 1. Under the contraction of the first pneumatic finger 2, the folded portions 1 move towards each other, and the arc-shaped groove 1b on the folded portion 1 presses the tape X onto the copper wire Y, thus fixing the tape X in a folded position with the copper wire Y. Therefore, this utility model achieves the purpose of fixing multiple copper wires Y with the tape X.

[0039] In this embodiment, the first linear motion component 201 pushes the second pneumatic finger 200 to make a linear reciprocating movement. Of course, depending on the requirements, the implementation of the first linear motion component 201 can be set to be multi-directional. As the first linear motion component 201 is prior art, its structure will not be further described.

[0040] like Figure 10 As shown, in order to enhance the clamping effect of the tape clip 202 on the tape X, the surfaces of the tape clips 202 that face each other are provided with mutually cooperating clamping grooves 202a and protrusions 202b. When clamping, the tape X is pushed into the clamping groove 202a by the protrusions 202b. This clamping method increases the contact area between the tape X and the tape clip 202, making the tape X less likely to loosen or fall off.

[0041] The tape feeding mechanism also includes a counter-tension cylinder 103 and a counter-tension mounting block 104. The counter-tension cylinder 103 is mounted on a base plate 3, and an opening structure 31 is provided on the base plate 3. The opening structure 31 has a length for the counter-tension mounting block 104 to move. The counter-tension mounting block 104 is disposed in the opening structure 31 and is connected to the piston rod of the counter-tension cylinder 103. In some embodiments, a rubber wheel shaft 102 is disposed on the counter-tension mounting block 104. By adjusting the position of the counter-tension mounting block 104 in the opening structure 31, the tape X can be kept in a stable tension state, ensuring the quality and efficiency of tape X transportation.

[0042] like Figure 5 As shown, after the tape X is dragged and jumps over the fold 1, the tape X is cut by the cutting mechanism 4.

[0043] like Figure 11-12 As shown, a cutter 41 is located between the last guide roller 101 along the X direction of the tape and the folded portion 1. The cutter mechanism 4 includes a cutter 41, a pressing block 42, a first slide rod 43, a second slide rod 44, a guide seat 45, a cutter cylinder 46, a tape pressing cylinder 47, and a fixing block 48. The guide seat 45 is mounted on the base plate 3. The first slide rod 43 and the second slide rod 44 pass through the guide seat 45 and are slidably connected to it. The cutter cylinder 46 is mounted on the base plate 3. The cutter cylinder 46 and the tape pressing cylinder 47 are connected to the cutter 41 and the pressing block 42 respectively through the first slide rod 43 and the second slide rod 44. The L-shape of the fixing block 48 is formed by the first connecting portion 48a and... The second connecting part 48b is connected to the first connecting part 48a, which maintains a vertically corresponding position with the pressure block 42 and is fixed to the base plate 3 by the second connecting part 48b. In addition, the first connecting part 48a also corresponds to the tape clamp 202 from left to right. The upper surface of the first connecting part 48a is provided with a guide opening 48a-a adapted to the width of the tape X. Under the action of the guide roller 101, the tape X passes through the guide opening 48a-a and jumps over the folding part 1. When it is necessary to cut the tape X, the tape pressing cylinder 47 drives the pressure block 42 to move towards the guide opening 48a-a, and finally presses the tape X against the guide opening 48a-a, so that the tape X is in a taut state.

[0044] The above "jumping over" means that after tape X is dragged by tape clamp 202, its starting end continues to be dragged even after intersecting with the copper wire Y path, as shown above. Figure 8 As shown.

[0045] like Figure 4 As shown, a second linear moving component 105 can also be provided. The second linear moving component 105 is provided on the base plate 3. The folding mechanism is provided on the second linear moving component 105. The second linear moving component 105 is used to adjust the distance between the folded part 1 and the copper wire Y, and the adjustment range is determined according to the number of copper wires Y.

[0046] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
