Description

Technical Field

[0001] This invention belongs to the field of heat shrink terminal forming technology, and particularly relates to a heat shrink terminal forming equipment for new energy connectors. Background Technology

[0002] Heat shrink terminals are electrical connection components that primarily use heat-shrinkable materials to achieve a tight connection and insulation protection for electrical conductors. Heat shrink terminals come in different product types, mainly including heat shrink ring terminals, heat shrink fork terminals, and waterproof heat shrink terminals. Waterproof heat shrink terminals are heat shrink tubing made of polyolefin through adhesive coating. They are used to protect connections, provide waterproofing and corrosion resistance, and can enhance fixation and vibration damping in rough environments. They also provide excellent insulation protection for electronic connectors. During use, heat shrink terminals require heating to rapidly shrink and form the connector. Molding equipment is needed during the heat shrink terminal forming process.

[0003] Chinese patent (CN115923168A) discloses a heat-shrinkable terminal forming device for connectors, comprising two moving components that move towards or away from each other. Each moving component includes a moving base and a clamping column rotatably mounted on the axis of the moving base; a guide column fixedly mounted on the moving base; a moving frame slidably sleeved on the guide column and driven by an external force to reciprocate along the guide column; a bracket mounted at the bottom of the moving frame, on which a pressure roller is rotatably mounted; and a shape memory alloy spring installed between the moving frame and the bracket. This device, while the heat-shrinkable tubing body shrinks due to heat, applies force to the surface of the heat-shrinkable tubing body through the pressure roller to flatten it. Before the heat-shrinkable tubing body and the bare metal terminal tube are fully bonded, the air in the gap between the heat-shrinkable tubing body and the bare metal terminal tube is completely expelled, preventing bulges or protrusions and improving the forming quality of the product. While current molding equipment can process heat-shrinkable terminals, it still has some shortcomings in use. These mainly manifest in that the equipment often only processes the heat-shrinkable terminals in one pass, and the single-pass molding effect is insufficient. Internal wrinkles and air bubbles cannot be effectively removed. Some equipment has features for air bubble removal, but because the position of the heat-shrinkable terminals cannot be adjusted, the processing effect is not satisfactory, resulting in poor practical application performance. To solve these problems, there is an urgent need for a heat-shrinkable terminal molding equipment for new energy connectors. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of current molding equipment, which, while capable of molding heat-shrinkable terminals, still have some drawbacks in use. These shortcomings mainly manifest in the fact that the equipment often only performs one molding operation on the heat-shrinkable terminals, and the single molding effect is insufficient. Internal wrinkles and air bubbles cannot be effectively treated. Some equipment has air bubble treatment features, but due to the inability to adjust the position of the heat-shrinkable terminals, the treatment effect is not satisfactory, resulting in poor practical application performance. Therefore, this invention proposes a heat-shrinkable terminal molding equipment for new energy connectors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heat shrink terminal forming device for new energy connectors, comprising a main temperature controller and a base cabinet. The base cabinet is fitted with a cabinet door via hinges. Two frames and a wire assembly are fixedly installed on the top of the base cabinet. The wire assembly is used for stable transmission of the new energy connector wire harness. A top shell is fixedly installed on the top of the two frames. The main temperature controller is provided on the top surface of the top shell. A bottom groove is provided on the bottom surface of the top shell. An internal motor is fixedly installed on one inner wall of the top shell. One end of the output shaft of the built-in motor is fixedly mounted with a bidirectional threaded shaft. Two heat-shrinkable terminal support and adjustment mechanisms are movably mounted on the outside of the bidirectional threaded shaft.

An adjustment motor is fixedly mounted on one inner wall of the base cabinet. One end of the output shaft of the adjustment motor is fixedly mounted with a drive stud. A heat-shrinkable terminal forming mechanism is movably mounted on the outside of the drive stud.

In the second forming process, it can move on the surface of the terminals to ensure the tightness between the heat-shrinkable terminals and the connecting wires. It can also provide secondary heating and make the hot airflow quickly distributed, further improving the forming effect and uniformity of the terminals. The overall equipment has good practical application effect.

A heat-shrink terminal mounting assembly is rotatably mounted inside the mounting ring.

[0009] As a further description of the above technical solution: The heat shrink terminal mounting assembly includes a mounting sleeve, which is rotatably mounted inside a mounting ring via an externally mounted swivel. A driven gear is fixedly mounted at one end of the mounting sleeve, and the driving gear and the driven gear are meshed with each other. Multiple built-in elastic anti-slip protrusions are provided on the inner surface of the mounting sleeve.

[0010] As a further description of the above technical solution: The heat-shrinkable terminal forming mechanism includes a slider, which is threadedly mounted on the outside of a drive stud through a threaded hole inside it. The slider is slidably connected to a travel groove on the top surface of the base cabinet.

[0011] As a further description of the above technical solution: A support block is fixedly installed at the top of the slider, and an installation frame is fixedly installed at the top of the support block via a connecting rod. An electric heating tube is installed inside the installation frame, and multiple air outlets are provided on the outer surface of the installation frame. Pressing components are provided on both the upper and lower inner surfaces of the installation frame, and walking exhaust components are provided on both outer walls of the installation frame.

[0012] As a further description of the above technical solution: The pressing assembly includes an electrically controlled push rod, which is fixedly installed on the inner walls of the top and bottom surfaces of the mounting frame. An arc-shaped plate is fixedly installed at one end of the electrically controlled push rod, and a pressing sheet is movably installed on the outer side of the arc-shaped plate through a pressing spring.

[0013] As a further description of the above technical solution: The walking exhaust assembly includes an adjusting motor, which is fixedly mounted on the outer surface of the mounting frame. A telescopic seat is fixedly mounted on one end of the output shaft of the adjusting motor. Two wheel frames are fixedly mounted on one outer wall of the telescopic seat, and a mounting shaft is rotatably mounted between the two wheel frames.

[0014] As a further description of the above technical solution: A traveling wheel is fixedly installed at the middle position of the mounting shaft, and a number of exhaust protrusions are provided on the outer surface of the traveling wheel. Turbidator blades are fixedly installed on both sides of the mounting shaft.

[0015] As a further description of the above technical solution: The wire assembly includes a lifting platform, which is fixedly installed on the top surface of the base cabinet. A mounting cover is fixedly installed on the top surface of the lifting platform. An inlet and an outlet are respectively provided on both sides of the mounting cover. A side plate is horizontally fixedly installed on one outer wall of the mounting cover. A conduction motor is fixedly installed on the other outer wall of the mounting cover. A conduction roller is fixedly installed at one end of the output shaft of the conduction motor.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, a heat-shrinkable terminal support adjustment mechanism and a heat-shrinkable terminal forming mechanism are provided. During operation, the distance between the two heat-shrinkable terminal support adjustment mechanisms is adjusted according to the specifications of the heat-shrinkable terminal by driving the bidirectional threaded shaft to rotate, so that it matches the specifications of the heat-shrinkable terminal to be formed. The heat-shrinkable terminal is then inserted between the two mounting sleeves. At this time, the connector wire harness to be connected is respectively guided into the heat-shrinkable terminal. At this time, the overall temperature controller is turned on to control the overall temperature below the top shell. The heat-shrinkable terminal will shrink after being heated, fixing the connector wire harness only in the terminal, completing the initial forming of the heat-shrinkable terminal. During this process, the drive motor can be controlled to turn on and drive the drive gear to rotate. The drive gear can drive the mounting sleeve with the driven gear to rotate, realizing the rotation of the heat-shrinkable terminal, so that its surface can be evenly heated and shrinked. At this time, the motor controls the drive stud to rotate, and the drive stud can drive the heat-shrinkable terminal forming mechanism on it to move. The telescopic seat controls the displacement of the traveling wheel, so that it contacts the surface of the heat-shrinkable terminal. The telescopic seat is rotated by a motor, positioning the traveling wheels in a horizontal position. As the heat-shrink terminal forming mechanism moves, the traveling wheels roll on the terminal surface. Simultaneously, the heating element inside the mounting frame activates, allowing hot air to escape through multiple outlets. The rolling wheels drive the turbulence vanes, which rapidly distribute the hot air around the heat-shrink terminals, ensuring even heating and secondary forming. This design allows the equipment to adjust the mounting structure's position according to the required specifications of the heat-shrink terminals, significantly expanding its applicability. Furthermore, the equipment enables multiple forming processes for the terminals. In the first forming process, the terminal rotates, improving heating uniformity and forming effect. In the second forming process, the traveling wheels move on the terminal surface, ensuring a tight fit between the heat-shrink terminal and the connecting wire. Secondary heating and rapid hot air distribution further enhance the forming effect and uniformity. Overall, the equipment demonstrates excellent practical application performance.

[0017] 2. In this invention, two pressing components are also provided on the heat-shrink terminal forming mechanism. When the terminal is formed for the second time, the electric control push rod is driven to move the pressing sheet, so that it fits tightly against the outer surface of the terminal. As the heat-shrink terminal forming mechanism moves, the pressing sheet can slide on the terminal surface, effectively squeezing out the air bubbles inside the terminal. At the same time, since several venting protrusions are provided on the outer surface of the traveling wheel, the venting protrusions can also play a good venting role when the traveling wheel rolls on the surface of the heat-shrink terminal. The combination of the two further improves the venting effect of the heat-shrink terminal and improves the application effect of the equipment.

[0018] 3. In this invention, by providing a matching wire assembly, after the terminal is installed, when the connector wire harness is fed in, the connector wire harness is passed through the inlet, the conduction motor is turned on, the conduction motor can drive the conduction roller to rotate, the conduction roller can transmit the wire harness in, and finally the wire harness can be sent out through the outlet. The wire harness, which is straightened by the conduction roller, can be directly passed into the installed heat shrink terminal, which is convenient for subsequent operations. Through this design, the automatic wire guiding function of the connector wire harness can be completed automatically, improving the working efficiency and effect of the equipment.

A plurality of built-in elastic anti-slip protrusions 634 are provided on the inner surface of the mounting sleeve 633.

[0034] The heat-shrink terminal forming mechanism 8 includes a slider 83, which is threaded onto the outside of the drive stud 12 through a threaded hole inside it. The slider 83 is slidably connected to a travel groove on the top surface of the base cabinet 4. A support block 82 is fixedly installed on the top of the slider 83. A mounting frame 81 is fixedly installed on the top of the support block 82 through a connecting rod. An electric heating tube is installed inside the mounting frame 81. Multiple air outlets 84 are provided on the outer surface of the mounting frame 81. Pressing components 85 are provided on both the upper and lower inner surfaces of the mounting frame 81. Traveling exhaust components 86 are provided on both outer walls of the mounting frame 81.

[0035] The walking exhaust assembly 86 includes an adjusting motor 861, which is fixedly mounted on the outer surface of the mounting frame 81. A telescopic seat 862 is fixedly mounted on one end of the output shaft of the adjusting motor 861. Two wheel frames 863 are fixedly mounted on one outer wall of the telescopic seat 862. An installation shaft 864 is rotatably mounted between the two wheel frames 863. A walking wheel 866 is fixedly mounted at the middle position of the installation shaft 864. Several exhaust protrusions 867 are provided on the outer surface of the walking wheel 866. Baffles 865 are fixedly mounted on both sides of the installation shaft 864.

[0036] The specific implementation method is as follows: During operation, firstly, according to the specifications of the heat-shrinkable terminal, the distance between the two heat-shrinkable terminal support adjustment mechanisms 6 is adjusted by driving the bidirectional threaded shaft 11 to rotate, so that it matches the specifications of the heat-shrinkable terminal to be formed. The heat-shrinkable terminal is then inserted between the two mounting sleeves 633. At this time, the connector wire harness to be connected is respectively guided into the heat-shrinkable terminal. At this time, the overall temperature controller 1 is turned on to control the overall temperature below the top shell 2. The heat-shrinkable terminal will shrink after being heated, fixing the connector wire harness only in the terminal, completing the initial forming of the heat-shrinkable terminal. During this process, the drive motor 65 can be turned on to drive the drive gear 64 to rotate. The drive gear 64 can drive the mounting sleeve 633 with the driven gear 631 to rotate, realizing the heat-shrinkable terminal... The surface is rotated to ensure even heating. At this time, the motor 13 controls the drive stud 12 to rotate, which in turn drives the heat shrink terminal forming mechanism 8 on it to move. The telescopic seat 862 controls the displacement of the traveling wheel 866 so that it contacts the surface of the heat shrink terminal. The motor 861 controls the telescopic seat 862 to rotate, so that the traveling wheel 866 is in a horizontal position. At this time, as the heat shrink terminal forming mechanism 8 moves, the traveling wheel 866 can roll on the surface of the terminal. At this time, the electric heating tube inside the mounting frame 81 is turned on, and hot air can be ejected through multiple air outlets 84. The rolling traveling wheel 866 can drive the baffle 865 to rotate. The baffle 865 can make the hot air flow quickly and distribute it around the heat shrink terminal, so that the heat shrink terminal is evenly heated for secondary forming.

[0037] Through this design, the equipment can adjust the position of the installation structure according to the specifications of the heat-shrinkable terminals to be formed, greatly improving the applicability of the equipment. At the same time, the equipment can perform multiple forming processes for the terminals. In the first forming process, it can drive the terminals to rotate, improving the heating uniformity of the terminals and enhancing the forming effect. In the second forming process, it can move on the surface of the terminals, ensuring the tightness between the heat-shrinkable terminals and the connecting wires. It can also provide secondary heating and rapidly distribute the hot airflow, further improving the forming effect and uniformity of the terminals. Overall, the equipment has good practical application performance.

[0038] The pressing assembly 85 includes an electrically controlled push rod 854, which is fixedly installed on the inner walls of the top and bottom surfaces of the mounting frame 81. An arc-shaped plate 853 is fixedly installed at one end of the electrically controlled push rod 854, and a pressing sheet 851 is movably installed on the outer side of the arc-shaped plate 853 through a pressing spring 852.

[0039] The specific implementation method is as follows: When the terminal is subjected to secondary forming, the electric control push rod 854 is driven to work and drive the pressing sheet 851 to move, so that it is tightly attached to the outer surface of the terminal. As the heat shrink terminal forming mechanism 8 moves, the pressing sheet 851 can slide on the terminal surface, effectively pressing out the air bubbles inside the terminal. At the same time, since several venting protrusions 867 are provided on the outer surface of the traveling wheel 866, the venting protrusions 867 can also play a good venting role when the traveling wheel 866 rolls on the surface of the heat shrink terminal. The combination of the two further improves the venting effect of the heat shrink formed terminal and improves the application effect of the equipment.

[0040] The wire assembly 7 includes a lifting platform 77, which is fixedly installed on the top surface of the base cabinet 4. A mounting cover 74 is fixedly installed on the top surface of the lifting platform 77. An inlet 71 and an outlet 76 are respectively provided on both sides of the mounting cover 74. A side plate 75 is horizontally fixedly installed on one outer wall of the mounting cover 74. A conduction motor 72 is fixedly installed on the other outer wall of the mounting cover 74. A conduction roller 73 is fixedly installed at one end of the output shaft of the conduction motor 72.

[0041] The specific implementation method is as follows: After the terminal is installed, when the connector wire harness is fed in, the connector wire harness is inserted through the inlet 71, the conduction motor 72 is turned on, the conduction motor 72 can drive the conduction roller 73 to rotate, the conduction roller 73 can transmit the wire harness, and finally the wire harness can be sent out through the outlet 76. The wire harness that has been straightened by the conduction roller 73 can be directly inserted into the installed heat shrink terminal, which is convenient for subsequent operations.

[0042] This design enables automatic wiring of connector harnesses, improving the efficiency and effectiveness of the equipment.

[0043] Working principle: During operation, the distance between the two heat shrink terminal support adjustment mechanisms 6 is adjusted by driving the bidirectional threaded shaft 11 to rotate according to the specifications of the heat shrink terminal, so that it matches the specifications of the heat shrink terminal to be formed, and the heat shrink terminal is inserted between the two mounting sleeves 633. After the terminal is installed, when the connector wire harness is fed in, the connector wire harness is inserted through the inlet 71. The conduction motor 72 is turned on, which drives the conduction roller 73 to rotate. The conduction roller 73 can transmit the wire harness in, and finally the wire harness can be sent out through the outlet 76. The wire harness, which is straightened by the conduction roller 73, can be directly inserted into the installed heat shrink terminal. At this time, the overall temperature controller 1 is turned on to control the overall temperature below the top shell 2. The heat shrink terminal will shrink after being heated, fixing the connector wire harness only in the terminal, completing the initial forming of the heat shrink terminal. During this process, the drive motor 65 can be turned on to drive the drive gear 64 to rotate. The drive gear 64 can drive the mounting sleeve 633 with the driven gear 631 to rotate, realizing the rotation of the heat shrink terminal. The heat shrink terminal forming mechanism 8 is moved by the drive stud 12, which is controlled by the motor 13 to rotate. The drive stud 12 can move the heat shrink terminal forming mechanism 8 on it. The telescopic seat 862 controls the displacement of the traveling wheel 866 so that it contacts the surface of the heat shrink terminal. The motor 861 controls the rotation of the telescopic seat 862 so that the traveling wheel 866 is in a horizontal position. At this time, as the heat shrink terminal forming mechanism 8 moves, the traveling wheel 866 can roll on the surface of the terminal. At this time, the electric heating tube inside the mounting frame 81 is turned on, and hot air can be sprayed out through multiple air outlets 84. The rolling traveling wheel 866 can drive the baffle 865 to rotate. The baffle 865 can make the hot air flow quickly and distribute it around the heat shrink terminal so that the heat shrink terminal is evenly heated for secondary forming. During the secondary forming of the terminal, the electric control push rod 854 is driven to move the pressing sheet 851, making it tightly fit against the outer surface of the terminal. As the heat shrink terminal forming mechanism 8 moves, the pressing sheet 851 can slide on the terminal surface, effectively squeezing out air bubbles inside the terminal. At the same time, since several venting protrusions 867 are provided on the outer surface of the traveling wheel 866, the venting protrusions 867 can also play a good venting role when the traveling wheel 866 rolls on the surface of the heat shrink terminal. The combination of the two further improves the venting effect of the heat shrink formed terminal.
