Description

Technical Field

[0001] This invention relates to the field of packaging machine technology, specifically to an insulating packaging machine for manufacturing miniature transformers. Background Technology

[0002] As a core component of electronic devices, miniature transformers are widely used in various electronic products, such as mobile phones, computers, and smart home devices. The quality of their insulation encapsulation plays a decisive role in the electrical performance, stability, and service life of the transformer. As electronic devices continue to develop towards miniaturization and high performance, the requirements for the insulation encapsulation of miniature transformers are also increasing. However, the current insulation encapsulation technology and equipment for manufacturing miniature transformers have many bottlenecks, making it difficult to meet the development needs of the industry.

[0003] Currently, the integrity and stability of the bonding of the encapsulation material is a major challenge in the insulation encapsulation process of micro transformers. Existing encapsulation methods often fail to ensure that the encapsulation material is tightly and evenly bonded to the micro transformer. Taking the common thin-film encapsulation as an example, when the traditional method covers the micro transformer with two sets of films, the bonding is often not tight. This allows external moisture, dust and other impurities to easily penetrate into the transformer, affecting its insulation performance and electrical parameters, thereby reducing the reliability and service life of the transformer.

[0016] (III) Beneficial Effects

[0017] This invention provides an insulation encapsulation machine for manufacturing miniature transformers. It has the following beneficial effects:

[0018] (I) The insulating encapsulation machine for manufacturing a miniature transformer, by setting up a wrapping component, can quickly heat-melt the polyethylene film in the wrapping component, firmly bonding the two sets of films together. This efficient heat-melting method not only improves the encapsulation speed, but also ensures the sealing and firmness of the encapsulation, enhances the protection of the miniature transformer, and prevents external factors from damaging the transformer. During the sliding process, the cutter can not only cut the heat-melted polyethylene film, but the heating wire set on the cutter can also heat-melt the film at the same time as cutting it, thereby blocking the falling miniature transformer and improving the success rate of encapsulation and the yield rate of products.

[0019] (II) The insulation encapsulation machine for manufacturing a miniature transformer, by setting up a cleaning component, through structures such as an air bladder, a sliding plate, an air supply pipe, and an air blowing pipe, can promptly blow out gas when the pressure plate descends to remove debris from the discharge shell. This automatic debris removal function maintains a clean working environment, avoids contamination of the miniature transformer and encapsulation material by debris, improves the quality and reliability of the encapsulated products, and reduces product failures and defect rates caused by debris. When the pressure plate rises, the air bladder automatically resets under the action of the top spring and draws in outside air to prepare for the next air blowing cleaning operation. This automatic reset design enables the cleaning component to work continuously and stably without manual intervention, improving the automation level and operating efficiency of the equipment.

[0020] (III) The insulation packaging machine for manufacturing a micro transformer, by setting a limiting component, constrains the entry direction and range of the polyethylene film by the limiting frame, and in conjunction with the rubber ring on the active roller and the tension spring on the driven roller, can ensure that the two sets of polyethylene films are transported stably and intermittently. This transport method ensures the consistency of the position and tension of the film in the subsequent packaging process, improves the accuracy and quality of packaging, and reduces packaging defects caused by unstable film transport, such as wrinkles and offsets.

[0021] (iv) The insulating encapsulation machine for manufacturing micro transformers, by setting up a feeding component, utilizes a transmission structure such as a stepper motor-driven active roller, active wheel, driven wheel and connecting belt pulley to realize the intermittent feeding of micro transformers. This orderly feeding method matches the conveying rhythm of polyethylene film, so that each micro transformer can reach the designated position for encapsulation at the appropriate time, avoiding transformer accumulation or untimely supply, and improving encapsulation efficiency and production continuity.

The top of the connecting shaft 81 is fixedly connected to the outer wall of the pressure plate 73.

[0036] The limiting component 6 includes a feeding bin 61, with a limiting frame 62 fixedly connected to the top of the feeding bin 61. The outer wall of the feeding bin 61 is fixedly connected to the inner wall of the top of the frame 4. A driven roller 66 is rotatably connected to the top of the frame 4 via a fixed seat 68, and the bottom of the fixed seat 68 is fixedly connected to the top of the frame 4.

A rubber ring 65 is fixedly connected to the outer wall of the driving roller 64. The rubber ring 65 has a large friction force, and when the polyethylene film passes between the driving roller 64 and the driven roller 66, the rubber ring 65 can better... The polyethylene film is gripped, and rubber rings 65 are arranged in a linear array along the central axis of the drive roller 64. A stepper motor 63 is fixedly connected to the top of the frame 4 via a fixed frame.

[0037] The material discharge assembly 5 includes a material discharge shell 51. The outer wall of the material discharge shell 51 is rotatably connected to a connecting belt pulley 55 via a connecting frame 54, and the outer wall of the connecting frame 54 is fixedly connected to the outer wall of the material discharge shell 51. A rotating wheel 53 is fixedly connected to the outer wall of the connecting belt pulley 55. The rotating wheel 53 is located inside the material discharge shell 51.

The inner wall of the connecting frame 54 is rotatably connected to the outer wall of the connecting belt pulley 55. The outer wall of the venting pipe 52 is fixedly connected to the outer wall of the blowing pipe 88. The inner wall of the connecting belt pulley 55 is in frictional contact with the inner wall of the second belt 614. When the driven wheel 613 drives the connecting belt pulley 55 to rotate via the second belt 614, the rotating wheel 53 rotates synchronously, thereby intermittently releasing the micro transformers inside the material discharge shell 51, realizing the orderly release of the micro transformers, and preparing for subsequent packaging work.

[0038] This insulation encapsulation machine mainly consists of a frame 4, a feeding component 1, a hot-melt component 2, and a cleaning component 8. The frame 4 serves as the basic support structure of the entire equipment. Its bottom outer wall is slidably connected to the material box 3, which facilitates the replacement of the material box 3 and the replenishment of materials. The feeding component 1 is fixedly installed on the top of the frame 4 and includes a limiting component 6 and a feeding component 5, which are responsible for the orderly supply of materials. The hot-melt component 2 can slide on the inner wall of the frame 4. Its core wrapping component 7 is also slidably connected to the inner wall of the frame 4, which is used to complete the hot-melt of polyethylene film and the wrapping operation of micro transformers. The cleaning component 8 is fixed on the outer wall of the frame 4 and is responsible for removing debris generated during the encapsulation process to ensure a clean working environment.

[0039] The top of the feed hopper 61 in the limiting assembly 6 is equipped with a limiting frame 62, which serves to initially constrain the entry direction and range of the two sets of polyethylene films, ensuring that the two sets of polyethylene films can enter stably. At the top of the frame 4, two sets of driven rollers 66 are rotatably connected by a fixed seat 68, and two sets of active rollers 64 are also rotatably installed. The stepper motor 63 is firmly installed at the top of the frame 4 by a fixed frame, and its output end is connected to the outer wall of the active roller 64 by a belt. When the stepper motor 63 starts, its output power is transmitted to the active roller 64 through the belt, driving the active roller 64 to rotate, and the stepper motor 63 rotates intermittently.

[0040] A pulley is provided on the outer wall of a set of drive rollers 64. The pulley is connected to the pulley 69 and the tensioning wheel 611 via the first belt 610. The tensioning wheel 611 plays a crucial role, as it can adjust the tension of the first belt δ10 to ensure that the belt does not slip during transmission, thereby ensuring the stability and reliability of power transmission. Rubber rings 65 arranged in a linear array along the central axis are fixed on the outer wall of the drive rollers 64. These rubber rings 65 have a large friction force. When the polyethylene film passes between the drive rollers 64 and the driven rollers 66, the rubber rings 65 can better grip the polyethylene film, realizing stable intermittent conveying of the two sets of polyethylene films.

[0041] A tension spring 67 is connected to the outer wall of the driven roller 66. The other end of the tension spring 67 is fixed to the top of the frame 4. The tension generated by the tension spring 67 enables the driven roller 66 to fit tightly against the driving roller 64, thereby better clamping the polyethylene film. During the polyethylene film conveying process, the driven roller 66 and the driving roller 64 cooperate with each other to form a stable conveying channel, ensuring that the polyethylene film can be conveyed intermittently in the predetermined direction.

[0042] A set of driving rollers 64 also has a driving wheel 612 fixed on its outer wall. The driving wheel 612 meshes with the driven wheel 613. The inner wall of the driven wheel 613 is connected to the connecting pulley 55 of the feeding assembly 5 through the second belt 614. When the driving roller 64 rotates, the driving wheel 612 drives the driven wheel 613 to rotate. The driven wheel 613 then transmits power to the connecting pulley 55 through the second belt 614, providing power support for the operation of the feeding assembly 5.

[0043] The top of the discharge shell 51 of the discharge assembly 5 is connected to the bottom of the feed hopper 61. The micro transformer enters the discharge shell 51 from the feed hopper 61. The outer wall of the discharge shell 51 is rotatably connected to the connecting pulley 55 through the connecting frame 54. The outer wall of the connecting pulley 55 is fixed with a rotating wheel 53, and the rotating wheel 53 is located inside the discharge shell 51. When the driven wheel 613 drives the connecting pulley 55 to rotate through the second belt 614, the rotating wheel 53 rotates synchronously, thereby intermittently releasing the micro transformer in the discharge shell 51, realizing the orderly release of the micro transformer, and preparing for the subsequent packaging work.

[0044] The bottom of the hydraulic cylinder 71 in the package assembly 7 is fixed to the outer wall of the frame 4 by the bracket 72. The telescopic end of the hydraulic cylinder 71 is connected to the pressure plate 73. When the telescopic end of the hydraulic cylinder 71 performs telescopic movement, it will drive the pressure plate 73 to move up or down. The two sides of the pressure plate 73 are connected to the sliding block 78 by the connecting column 74. The sliding block 78 can slide on the inner wall of the frame 4.

[0045] The inner walls on both sides of the frame 4 are slidably connected to sliders 75. The outer wall of sliders 75 is fixedly installed with heating wires 711 and cutters 710. The outer wall of sliders 75 is connected to wedges 79 by rollers 77. When the extension end of hydraulic cylinder 71 slides down, pressure plate 73 will also fall down. Pressure plate 73 drives slider 78 to slide down the inner wall of frame 4 through connecting column 74. During the sliding process of slider 78, rollers 77 will roll on wedges 79. Due to the special shape design of wedges 79, rollers 77 will generate a lateral thrust when rolling on them, pushing sliders 75 to slide on the inner wall of frame 4.

[0046] The sliding of the two sets of sliders 75 causes the heating wires 711 on the corresponding sliders 75 to gradually approach the polyethylene film, and the two sets of polyethylene films are pressed together by the two sets of sliders 75. When the heating wires 711 are energized, they generate high temperature and heat-melt the polyethylene film, thereby heat-melting and bonding the two sets of polyethylene films. The cutter 710 will cut the heat-melted polyethylene film as the sliders 75 continue to slide, thereby completing the wrapping action of the micro transformer.

[0047] Spring plates 76 are fixedly connected to the outer walls on both sides of the slider 75. The spring plates 76 play an important role in buffering and resetting during the sliding process of the slider 75. When the slider 75 slides under the push of the roller 77, the spring plate 76 will undergo elastic deformation to absorb part of the impact force and prevent the slider 75 from colliding violently with the inner wall of the frame 4, thereby ensuring the stability of the slider 75's movement. When the extension end of the hydraulic cylinder 71 retracts and the pressure plate 73 rises, the elastic restoring force of the spring plate 76 will help the slider 75 return to its initial position, preparing for the next wrapping operation.

[0048] The mounting bracket 82 of the cleaning component 8 is fixed to the outer wall of the frame 4. The top of the fixing plates 89 on both sides of the mounting bracket 82 is connected to an airbag 85. The top of the airbag 85 is connected to a sliding plate 83. The bottom of the sliding plate 83 is connected to a top spring 84. The inner wall of the fixing plate 89 is connected to an air supply pipe 86. The air supply pipe 86 is connected to an air blowing pipe 88 through a hose 87. The inner wall of the fixing plate 89 is also provided with a one-way valve 810.

[0049] The connecting shaft 81 at the top of the slide plate 83 is connected to the outer wall of the pressure plate 73. When the pressure plate 73 descends, the slide plate 83 is driven to descend through the connecting shaft 81. The descent of the slide plate 83 will squeeze the air bag 85, increasing the gas pressure inside the air bag 85. Due to the presence of the one-way valve 810, the gas can only be blown out from the air blowing pipe 88 to the air guide pipe 52 through the air supply pipe 86 and the hose 87. The blown gas has a certain pressure and flow rate, which can remove the debris in the discharge shell 51, so that the debris on the micro transformer is blown out from the side of the discharge shell 51, ensuring the cleanliness of the working environment and avoiding the impact of debris on subsequent packaging operations.

[0050] When the pressure plate 73 rises, the slide plate 83 returns to its original position under the elastic restoring force of the top spring 84. At this time, the pressure inside the airbag 85 decreases, and outside air enters the airbag 85 through the one-way valve 810 under the action of atmospheric pressure, preparing for the next air blowing and cleaning operation.

[0051] Throughout the entire insulation encapsulation process, the various components work closely together to form an organic whole. The feeding component 1 starts first, with the stepper motor 63 driving the active roller 64 to rotate intermittently, conveying the polyethylene film intermittently from the infeed hopper 61 to the discharge shell 51. The micro-transformer is then orderly discharged through the discharge component 5. After the micro-transformer reaches the designated position, the heat-melting component 2 begins operation. The hydraulic cylinder 71 pushes the pressure plate 73 downwards, causing the slider 75 of the wrapping component 7 to slide, allowing the heating wire 711 to heat-melt the material. The cutter 710 then cuts and wraps the material. The cutter 710 is also equipped with a set of heating wires 711. The heating wires 711 heat the cutter 710, thereby cutting the polyethylene film and simultaneously melting the polyethylene film on the cutter 710, thus preventing the falling miniature transformer. As the pressure plate 73 descends, the slide plate 83 of the cleaning component 8 also descends, squeezing the airbag 85 and blowing gas through the air pipe 88 to remove debris. After one sealing operation is completed, the hydraulic cylinder 71 retracts, the pressure plate 73 rises, and all components reset, ready for the next sealing operation.
