[0001] The utility model relates to the field of stripping and twisting wires on transformers, in particular to a stripping mechanism for winding leads. Background Art

[0002] A transformer is a device with copper wire wrapped around a frame. In today's society, it is a very mature electrical component.

[0003] To date, transformers have been used in all walks of life. During this application process, the transformer's structure has undergone a series of changes in order to adapt to this environment. Therefore, there are a large number of customized transformers on the market.

[0004] After investigation, it was found that the common method of stripping, such as patent application number CN202222728892.X, which is named a transformer insulation wire stripping machine, is to use a cutter to strip. However, the cutter has a service life. In addition, the tool replacement needs to be performed manually, which does not meet the needs of contemporary society in terms of cost and production efficiency. Utility Model Content

[0005] In order to solve the above problems, the utility model provides a stripping mechanism for winding leads, which replaces the use of cutters by laser stripping. In effect, it can effectively improve production efficiency and save production costs.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a stripping mechanism for winding leads, characterized in that it includes a jig and a laser head, a transformer is arranged in the jig, and the wires on the transformer extend out of the jig to coincide with the light emitted by the laser head; it also includes a supporting mechanism and a wire board, an assembly space is provided in the supporting mechanism, the transformer is located in the assembly space, the wire board and the supporting mechanism are arranged at intervals, and wire holes are provided at the upper edges of the wire board and the supporting mechanism, the wires of the transformer pass through the two wire holes, and are maintained in a horizontal state to coincide with the light projected by the laser.

[0007] Furthermore, a soot blowing mechanism is included, which is located below the jig and blows up the ash and smoke below the jig by releasing compressed airflow.

[0008] Furthermore, the soot blowing mechanism comprises a pair of air outlet pipes extending in the length direction, both ends of the air outlet pipes are air inlet ends, and a plurality of soot blowing holes are arranged on the surface of the air outlet pipes, and the compressed air flows out from the soot blowing holes.

[0009] Furthermore, it also includes a smoking mechanism, which is a smoking hood with a negative pressure unit. The side surface of the smoking hood and the fixture extending along the length direction corresponds to the smoking port of the smoking hood.

[0010] Furthermore, it also includes a forward and reverse auxiliary mechanism, and the pneumatic finger clamping and positioning mechanism on the forward and reverse auxiliary mechanism performs a flipping motion to face the back side of the wire to the laser head.

[0011] Furthermore, it also includes a jig mother seat, which is a supporting mechanism formed on the mother seat bottom plate. A magnet is arranged in the jig mother seat, and is connected to the jig by magnetic adsorption.

[0012] Furthermore, the fixture includes a pair of limit plates, which are inserted between two protruding structures of the transformer to support the transformer through the edges.

[0013] Furthermore, the fixture also includes a group of auxiliary parts, which are distributed at two extreme positions extending along the length direction of the limiting plate. Any limiting plate is slidably connected to the auxiliary parts, and the two limiting plates are detachably connected.

[0014] Beneficial effects of the utility model:

[0015] The utility model adopts a laser head as a method for stripping the wire. The heat of the laser can instantly evaporate the outer coating of the wire. This stripping method does not need to be replaced like a tool. In terms of efficiency, the large-area projection of the laser is faster and has higher production capacity than stripping with a tool.

[0047] The following detailed description of example embodiments is provided with reference to the accompanying drawings. The same reference numerals in different drawings represent the same or similar elements. Moreover, the drawings are not necessarily drawn to scale. The following detailed description does not limit the present invention. The scope of protection of the present invention is defined by the appended claims.

[0048] Figure 1 It is a three-dimensional diagram of a transformer 1. There are two wires (wire 1a and wire 1b) on the transformer 1. As can be seen from the figure, wire 1a and wire 1b are distributed on the same horizontal plane and extend in opposite directions to each other.

[0049] Figure 2 The utility model is a three-dimensional diagram of the utility model, which is a winding machine. The winding machine can be used to strip, twist and solder the wires on the transformer 1 (refer to Figure 3-5 ).

[0050] like Figure 6-8 As shown, the utility model includes a positioning mechanism 8 and a stripping part, a laser head 51 and a forward and reverse auxiliary mechanism 52 constitute a stripping mechanism 5 for removing the outer sheath of the wire, a wire passing hole 3b' is reserved on the side of the positioning mechanism 8, and the transformer 1 installed inside the positioning mechanism 8, the wires 1a and 1b thereof pass through the wire passing hole 3b' on the side of the positioning mechanism 8, and the forward and reverse auxiliary mechanism 52 is provided with a pneumatic finger 53. When the pneumatic finger 53 keeps the positioning mechanism 8 in a clamping state, the flipping movement implemented by the forward and reverse auxiliary mechanism 52 will pull the positioning mechanism 8 to do the same flipping movement.

[0051] The laser head 51 is installed above the positioning mechanism 8. The range of the laser emitted by the laser head 51 is controllable and is directed to the melting area of ​​the wires 1a and 1b outside the positioning mechanism 8. For the wires 1a and 1b extending outside the positioning mechanism 8, after being irradiated by the laser, the non-metallic outer layer and the insulating inner layer serving as the outer coating are thermally decomposed and melted and evaporated on the surface of the core 1d.

[0052] like Fig. 9 As shown, it is a state diagram of the positioning mechanism 8 after being flipped. The coverage range of the laser head 51 to the wires 1a and B is only half of the periphery. After each irradiation of the laser head 51, the forward and reverse auxiliary mechanism 52 is required to flip the positioning mechanism 8.

[0053] In some embodiments, the forward and reverse auxiliary mechanism 52 is a motor-driven transmission wheel group 52a, and the pneumatic finger 53 is coaxially connected to any transmission wheel 52b in the transmission wheel group 52a. When the transmission wheel group 52a rotates, the pneumatic finger 53 also rotates with the transmission wheel group 52a, so that the positioning mechanism 8 can realize the flipping function.

[0054] In particular, the forward and reverse auxiliary mechanisms 52 have a pair, which are distributed at two extreme positions extending along the length direction of the positioning mechanism 8. In addition, among the transmission wheel groups 52a in the two forward and reverse auxiliary mechanisms 52, at least one transmission wheel 52b is coaxially connected to each other through a transmission shaft 52c. There is only one motor. When the motor drives any one of the transmission wheel groups 52a to rotate, the source power on the motor is transmitted to the other transmission wheel group 52a through the transmission shaft 52c, so as to perform synchronous rotation of the pneumatic fingers 53 in the two forward and reverse auxiliary mechanisms 52.

[0055] When the outer cover is thermally decomposed, not only smoke is generated, but also some ash is dropped. In order to solve the above problems, a smoking mechanism 53, an ash blowing mechanism 54 and a lifting mechanism 55 are provided. The lifting column on the lifting mechanism 55 can be embedded in the bottom surface of the positioning mechanism 8. Figure 11-13 As shown), the entire positioning mechanism 8 is pushed out from the conveyor belt 10 and maintained in a state where both ends are suspended. The forward and reverse auxiliary mechanism 52 is assembled in a linear moving mechanism. The two cooperate to maintain the positioning mechanism 8 in a suspended state. The soot blowing mechanism 54 can enter under the positioning mechanism 8 through another existing linear moving mechanism, and the ashes and smoke under the positioning mechanism 8 are blown up together by releasing compressed airflow. The side surface of the positioning mechanism 8 extending along the length direction corresponds to the smoking port of the smoking mechanism 53. The negative pressure formed by the smoking mechanism 53 draws away the smoke and ashes together and sends them out.

[0056] See also Fig.14 As shown, the soot blowing mechanism 54 includes a pair of air outlet pipes 54a extending along the length direction, both ends of the air outlet pipes 54a are connected to the air inlet unit, and a plurality of soot blowing holes 54b are provided on the surface of the air outlet pipes 54a. The compressed air flows out from the soot blowing holes 54b and flows from the bottom of the positioning mechanism 8 to the top of the positioning mechanism 8.

[0057] The smoking mechanism 53 is a smoking hood with a negative pressure unit, and its specific principle is the existing technology, so its structure will not be further described.

[0058] ( Figure 15-17 ) The positioning mechanism 8 is dedicated to positioning the transformer 1. The positioning mechanism 8 includes a jig 2, a jig base 3 and a wire board 3c, wherein the jig base 3 is composed of a base bottom plate 3a and a support mechanism 3b formed on the surface of the base bottom plate 3a. The support structure 3b is a surrounding structure, forming an assembly space surrounding the jig 2. The jig 2 is placed in the support structure 3b, and the freedom of the jig 2 is restricted by the support structure 3b. The wires on the jig 2 pass through the upper edge of the support structure 3b and fall onto the upper edge of the wire board 3c. The space between the support structure 3b and the wire board 3c is the range of irradiation of the laser head 51.

[0059] In order to prevent the wires from swinging, the wire holes 3b' on the upper edges of the support structure 3b and the wire plate 3c are opposite to each other.

[0060] The positioning mechanism 8 is made of metal material, and a magnet (not shown in the figure) is provided inside the support structure 3b. After the fixture 2 is installed in the support structure 3b, the positioning mechanism 8 is adsorbed in the assembly space due to the presence of the magnet, so the fixture will not fall off when it is flipped.

[0061] In some embodiments, the magnets are embedded in the inner wall of the support structure 3b.

[0062] Under the action of the fixture 2, the transformer 1 is maintained in a state where the wire corresponds to the wire hole 3b', and the wire is in a horizontal state.

[0063] The fixture comprises the following structure:

[0064] (like Figure 18-23 ) A limit plate, an auxiliary part 2c, a jig base 2d, and a jig top plate 2e. In particular, the limit plate and the auxiliary part 2c are arranged in pairs, and the limit plate and the auxiliary part 2c are enclosed in sequence. The limit plate is divided into a first limit plate 2a and a second limit plate 2b. The first limit plate 2a and the second limit plate 2b are connected by screws in a manner of maintaining a spacing, and the first limit plate 2a and the auxiliary part 2c are slidably connected. A connecting part 2f is provided on the jig base 2d, and the connecting part 2f extends toward the jig top plate 2e and is fixedly connected to the jig top plate 2e. The transformer 11 is constrained in the spacing between the first limit plate 2a and the second limit plate 2b.

[0065] When taking out or assembling the transformer 11 , it is only necessary to disassemble the second limiting plate 2 b and remove the screws. The disassembly method of the fixture 2 is relatively simple and less complicated.

[0066] In fact, the transformer 11 is positioned in the jig 2 by the limiting plate. Direction X is the axial direction of the transformer 11, and the raised structure 1c extends outward along the axial direction. Therefore, when the transformer 11 is in the jig 2, the raised structure 1c and the edge of the limiting plate are relative to each other. In addition, the width of the limiting plate is smaller than the spacing between the raised structures 1c. During assembly, the limiting plate is inserted between the raised structures 1c. After the two limiting plates are fixedly connected, the upper edge of the limiting plate supports the stroke of the raised structure 1c.

[0067] In some embodiments, a slide groove 2c′ is provided on the inner side of the auxiliary part 2c, and sliders 2a′ are respectively provided on both ends of the first limiting plate 2a. The slider 2a′ is slidably connected to the slide groove 2c′. A single sliding connection method can quickly establish a connection relationship with the auxiliary part 2c. The screw fixing method of the second limiting plate 2b can ensure that the distance between the second limiting plate 2b and the first limiting plate 2a is compact for the transformer 11.

[0068] In addition, compared with other connection methods, the sliding connection method eliminates the need for other auxiliary structures.

[0069] A limiting structure 2g is also provided on the fixture base 2d, which is located between the first limiting plate 2a and the second limiting plate 2b. The limiting structure 2g is a limiting block, which is inserted between the first limiting plate 2a and the second limiting plate 2b to prevent the transformer 1 from being crushed and exploded due to the distance between them being too close.

[0070] In the embodiment, there are a plurality of connecting portions 2 f , which are arranged in an array, and the transformers 11 are separated by the connecting portions 2 f .

[0071] The positioning mechanism 8 is transferred to another process via the conveyor belt 10. A pair of conveyor belts 10 are provided, and the lifting mechanism 55 is located between the two conveyor belts 10. After the stripping is completed, the lifting mechanism 55 is reset to retract the positioning mechanism 8 onto the conveyor belt 10, and the conveyor belt 10 transfers it to the next stranding process.

[0072] (like Figure 24-25 ) In the twisted wire part, it also involves cutting and twisting the wire core 1d. After stripping the wire sheath, the excess wire core 1d is cut short and the wire core 1d is rotationally twisted. The twisting is to prevent the wire ends from becoming loose, messy, and bent.

[0073] Specifically, the stranded wire portion includes a fixture removal mechanism 9 (such as Figure 26-28), the fixture removal mechanism 9 includes a base positioning platform 91, a first pneumatic finger 92, and a second pneumatic finger 93. The first pneumatic finger 92 transfers the positioning mechanism 8 to the base positioning platform 91 through a linear moving mechanism, and keeps the hole on the base positioning platform 91 relative to the positioning hole on the base bottom plate 3a. The two clamping ends 93a of the second pneumatic finger 93 are connected to a positioning rod 94 with a barb 95. The specific usage is as follows:

[0074] The compressed gas in the second pneumatic finger 93 is released in advance, so that the two clamping ends 93a are close to each other, and the corresponding positioning rods 94 are spliced ​​together. At this time, the circumference of the positioning rod 94 is smaller than the circumference of the two holes. After the first pneumatic finger 92 transfers the mother base plate 3a to the mother base positioning platform 91, the positioning rod 94 passes through the positioning hole of the mother base plate 3a. When compressed gas is added, the two clamping ends 93a move away from each other, so that the barb 95 is stuck on the upper edge of the positioning hole, and the mother base plate 3a is restricted on the mother base positioning platform 91. At this time, the double-station clamping mechanism 6 clamps the two ends of the fixture 2 to separate the fixture 2 from the mother base plate 3a.

[0075] (like Fig.29 ) Before the jig 2 is removed, the female seat positioning platform 91 is controlled by the linear moving mechanism to move the positioning mechanism 8 toward the wire cutting mechanism 11. The wire cutting mechanism 11 selects a cutting position for the stripped part to cut the wire.

[0076] The wire cutting mechanism 11 is a pneumatic scissors. In particular, four pneumatic scissors are provided and arranged in a rectangular manner. When cutting the wires, the wires on both sides of the positioning mechanism 8 can be cut at the same time.

[0077] The double-station clamping mechanism 6 is used to transfer the fixture 2 into the wire stranding mechanism 7 .

[0078] The double-station clamping mechanism 6 is composed of a linear moving mechanism and a third finger cylinder 61, and the linear moving mechanism drives the third finger cylinder 61 to do a reciprocating motion (the third finger cylinder 61 clamps the fixture and moves in the direction of the twisted wire).

[0079] like Fig.31 As shown, the wire twisting mechanism 7 includes a wire twisting installation platform and a wire twisting machine 71. The third finger cylinder 61 clamps the jig and moves toward the wire twisting installation platform. The wire twisting machine 71 approaches the wire twisting installation platform through a linear moving mechanism. The wire twisting machine 71 contains a clamping mouth for biting the end of the wire core 1d. The clamping mouth performs a self-rotating action to tighten the wire core 1d in a spiral manner.

[0080] A first limiting structure is also provided on the stranded wire installation platform. The first limiting structure has the same structure as the supporting structure and is used to support the wire core 1d. It cooperates with the second limiting mechanism in the double-station clamping mechanism 6 to constrain the position of the wire core 1d to a fixed position. After the clamping mouth moves to this position, it can bite the wire core 1d.

[0081] like Fig.30 As shown, the second limiting mechanism includes a lifting cylinder 72 and a pressing piece 73. The pressing piece 73 is located above the first limiting mechanism, and the lower edge of its side surface is a serrated limiting opening 73a. The piston cylinder of the lifting cylinder 72 is connected to the upper surface of the pressing piece 73. When performing the descending action, the wire is adjusted along the contraction of the inner side of the limiting opening 73a to adjust its position on the first limiting mechanism, thereby ensuring the relativity between the wire and the clamping opening.

[0082] The wire twisting machine 71 is a prior art, and its structure is not described in detail.

[0083] After twisting is completed as shown in the figure, it is sent to the soldering station by the double-station clamping mechanism 6. The soldering station includes a solder feeding mechanism 12a, a high-temperature tin furnace 12b, a low-temperature tin furnace 12c, and a solder shifting device (not shown in the figure). The jig 2 is moved from the solder feeding mechanism 12a to a specified position, and the position of the jig 2 is adjusted by the solder shifting device to rotate it so that the wire core 1d corresponds to the inside of the tin furnace. After the wire core 1d is immersed in the low-temperature tin furnace 12c, it is stained with some loose powder, and then enters the high-temperature tin furnace 12b, and finally moves to the cooling mechanism 12d to cool by blowing heat.

[0084] The soldering station is an existing technology, and the specific structure is not repeated here. The soldering station can also adopt a high-precision semi-automatic soldering machine such as 202221590914.4.

[0085] In addition, the limit plate, auxiliary part 2c, jig base 2d, and jig top plate 2e in the jig 2 are used to fully wrap the frame, tape, and wire package in the transformer 1. When soldering, they can prevent the tin liquid from contacting the frame, tape, and wire package, thereby avoiding the formation of tin beads or tin slag on the components of the transformer 1.

[0086] It is further explained that the linear moving mechanisms described above are all single new devices, and their structures are consistent with those in the prior art, so the specific description of their structures will not be repeated.

[0087] 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.
