Description

Technical Field

[0001] This utility model relates to the field of network transformer manufacturing technology, and in particular to a network transformer flipping and peeling device. Background Technology

[0002] In the production process of network transformers, after the pins and enameled wire winding process is completed, the stripping of the enameled wire is a crucial step to ensure the subsequent welding quality and electrical connection reliability. Although the insulating varnish layer on the surface of the enameled wire can effectively prevent current leakage and short circuits, the insulating varnish at the connection point must be precisely removed when welding to the pins to ensure that a good conductive path is formed at the weld. The most common method used in the industry for stripping wires involves using the heat of molten solder to burn off the outer layer of the wire at the connection point during the subsequent soldering process. While this method seems to combine the stripping and soldering processes and simplify the production flow, it has many insurmountable drawbacks in practical applications. First, the effectiveness of the stripping process is greatly affected by the temperature of the molten solder and the contact time. If the temperature of the molten solder is too high or the contact time is too long, the conductor material of the enameled wire will not only oxidize and become brittle due to overheating, affecting its mechanical strength and conductivity, but also the residue produced by the burning of the insulating varnish may adhere to the conductor surface, forming a conductivity barrier. Conversely, if the temperature is insufficient or the contact time is too short, the insulating varnish cannot be completely removed, and the residual varnish layer will cause problems such as poor soldering and false soldering at the solder joint, seriously affecting the stability of the electrical connection and increasing the signal transmission loss and failure risk of the network transformer. Secondly, the fluidity and wettability of molten solder are difficult to control precisely. During the hot stripping process, the molten solder may spread unexpectedly along the surface of the enameled wire, causing the areas where the insulation layer should be retained to be eroded, damaging the insulation performance of the enameled wire, causing short circuits between adjacent turns, and significantly reducing the product yield. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a network transformer flipping and peeling device.

[0004] A network transformer flipping and peeling device designed for this purpose includes a machine base, a receiving module, and a laser module; The receiving module is used to fix the network transformer and is rotatably arranged relative to the machine base. The machine base is provided with a drive module for driving the receiving module to rotate relative to the machine base. The laser module is positioned above the receiving module and is used to perform laser stripping of the enameled wires of the network transformer.

[0005] Preferably, the receiving module includes a receiving seat and an adjusting clamp; The receiving seat is rotatably configured relative to the machine base; The receiving seat is provided with a receiving cavity with an upper opening and a right opening. The adjusting clamp is located at the right opening of the receiving cavity. The adjusting clamp is movable left and right relative to the receiving seat; the receiving seat is provided with a fixed seat, and the fixed seat is provided with a linear drive element connected to the adjusting clamp.

[0006] Preferably, the receiving seat has openings on both the front and rear sides; A material feeding channel is provided on the machine platform on the front side of the receiving seat, and a material pushing module is provided on the machine platform on the rear side of the receiving seat. When the pusher module moves forward, it can extend into the receiving cavity, thereby pushing the network transformer in the receiving cavity into the unloading channel.

[0007] Preferably, the machine base is provided with a mounting base, and the receiving base is connected to a rotating shaft that is rotatably connected to the mounting base.

[0008] Preferably, the machine tool is equipped with a lifting module, and the laser module is connected to the lifting module and can move up and down relative to the machine tool under the drive of the lifting module.

[0009] Compared with the prior art, this utility model brings many significant benefits through innovative structural design: First, the precision and quality of stripping are significantly improved. Using a laser module for stripping enameled wires allows for highly concentrated and controllable laser energy, precisely targeting the area to be stripped. This achieves efficient and thorough removal of the insulating enamel layer, effectively avoiding the problems of incomplete stripping (residual enamel layer) or over-treatment (conductor oxidation and embrittlement) caused by improper temperature or time control in traditional molten solder stripping methods. This significantly improves the consistency and reliability of enameled wire stripping, providing a solid guarantee for subsequent welding quality. Secondly, it effectively protects the network transformer and other areas of the enameled wire. The housing module can fix the network transformer and rotate relative to the machine under the drive module. Combined with the precise action of the laser module, it can flexibly adjust the stripping position and angle, ensuring that the laser only acts on the target stripping area, avoiding damage to the insulation layer of the non-stripped parts of the enameled wire and other components of the network transformer. This fundamentally solves the problems of insulation performance damage and short circuits between adjacent turns caused by unintended diffusion of molten solder in traditional soldering methods, and significantly improves the product qualification rate.

[0019] See Figures 1-3 A network transformer reversing and stripping device includes a machine base 10, a receiving module 20, and a laser module 30; the receiving module 20 is used to fix the network transformer 110 and is rotatably arranged relative to the machine base 10, and the machine base 10 is provided with a drive module 60 for driving the receiving module 20 to rotate relative to the machine base 10; the laser module 30 is arranged above the receiving module 20 and is used to perform laser stripping on the enameled wires of the network transformer 110.

[0020] In operation, this invention first fixes the network transformer 110 onto the receiving module 20, initially positioning one row of pins of the network transformer opposite the laser module 30. After the laser module 30 is activated, it emits a laser to precisely strip the enameled wire at that row of pins. Once the enameled wire at that row of pins has been stripped, the drive module 60 on the machine base 10 drives the receiving module 20 to rotate relative to the machine base 10, thereby causing the network transformer 110 to rotate synchronously at a certain angle. This rotation causes the other row of pins on the network transformer that has not yet been stripped to rotate to a position opposite the laser module 30. The laser module 30 then restarts to strip the enameled wire at that row of pins. This cycle continues, adjusting the rotation of the receiving module 20 so that each row of pins of the network transformer is sequentially aligned with the laser module 30, thus completing the stripping operation for all rows of pins and ultimately achieving complete stripping of the enameled wire from the network transformer.

[0021] See Figure 2Regarding the feeding of the network transformer 110, an existing network transformer feeding mechanism can be used. Alternatively, a combination of an automatic gripping module 80 and a conveyor line 70 can be used, with the automatic gripping module 80 and conveyor line 70 employing existing technology. The conveyor line 70 is used to transport the network transformers 110 one by one. The automatic gripping module 80 uses pneumatic or magnetic suction to grip the network transformers 110 located within the conveyor line 70 and, in conjunction with multi-axis mechanical movement, transfers the network transformers 110 into the receiving module 20.

[0022] See Figure 2 The receiving module 20 includes a receiving base 210 and an adjusting clamp 220. The receiving base 210 is rotatably disposed relative to the machine base 10. The receiving base 210 is provided with a receiving cavity 200 with an upper opening and a right-side opening. The adjusting clamp 220 is disposed at the right-side opening of the receiving cavity 200. The adjusting clamp 220 is movable left and right relative to the receiving base 210. The receiving base 210 is provided with a fixing base 230, and the fixing base 230 is provided with a linear drive element 240 connected to the adjusting clamp 220. In use, the network transformer is placed into the receiving cavity 200 of the receiving base 210. The linear drive element 240 drives the adjusting clamp 220 to move to the left, engaging with the left side wall of the receiving cavity 200 to clamp the network transformer. Conversely, driving the adjusting clamp 220 to move to the right releases the network transformer. Its function is to adjust the left and right movement of the clamping plate to flexibly adapt to network transformers of different sizes, achieve stable clamping, and ensure that the network transformer is in a stable position during the flipping and peeling process, thus providing a reliable guarantee for the precise laser peeling.

[0023] See Figure 2 The receiving seat 210 has openings on both its front and rear sides. A feeding channel 40 is provided on the machine base 10 on the front side of the receiving seat 210, and a pushing module 50 is provided on the machine base 10 on the rear side of the receiving seat 210. When the pushing module 50 moves forward, it extends into the receiving cavity 200, thereby pushing the network transformer 110 inside the receiving cavity 200 into the feeding channel 40. Utilizing the openings on both sides of the receiving seat 210, after the network transformer completes the peeling process within the receiving cavity 200, the pushing module 50 moves forward and extends into the receiving cavity 200, pushing the network transformer 110 inside the cavity forward along the openings, ultimately entering the feeding channel 40 located on the machine base 10 on the front side of the receiving seat 210. Its function is to achieve automatic feeding of the network transformer. Through the cooperation of the pushing module and the feeding channel, it replaces manual handling, improving the automation and efficiency of production, while ensuring smooth product conveying after peeling, making the entire peeling process more continuous.

[0024] In this utility model, the pushing module 50 includes a pushing cylinder and a pushing rod connected to the pushing cylinder. The pushing rod is arranged to move back and forth relative to the machine base 10 and can extend from back to front into the receiving cavity 200 to push the network transformer 110 to move forward.

[0025] In this invention, the machine base 10 is provided with a mounting base 120, and the receiving seat 210 is connected to a rotating shaft 250 that is rotatably connected to the mounting base 120. The drive module 60 uses a motor, which rotates with the rotating shaft 250 through gear transmission or synchronous pulley and synchronous belt transmission. The rotating shaft 250 drives the receiving seat 210 to rotate relative to the mounting base 120.

[0026] See Figure 1 The machine platform 10 is equipped with a lifting module 300. The laser module 30 is connected to the lifting module 300 and can move up and down relative to the machine platform 10 under the drive of the lifting module 300.

[0027] The function of the lifting module 300 is to drive the laser module 30 to move up and down relative to the machine platform 10, flexibly adjust the distance between the laser module 30 and the network transformer 110 in the housing module 20, thereby adapting to network transformers of different heights and ensuring that the laser can be accurately focused on the area of ​​the enameled wire to be peeled, thus improving the adaptability of the peeling effect. The existing components that can be used in the lifting module 300 include: ball screw slide, synchronous belt linear module, electric push rod, etc. These components can stably realize linear lifting motion with high precision and meet the position adjustment requirements. Existing components that can be used in laser module 30 include fiber lasers and CO2 lasers. Among them, fiber lasers have concentrated energy and wavelengths suitable for processing metals and insulating materials, while CO2 lasers have a significant effect on peeling organic insulating varnish layers. Both can meet the process requirements for stripping enameled wires.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
