Description

Technical Field

[0001] This utility model relates to a heat shrink machine, and more particularly to a heat shrink machine for wire harness heat shrink tubing used in the field of wire harness processing. Background Technology

[0002] A wire harness heat shrink tubing heat shrinker is a device specifically designed for heating and shrinking heat shrink tubing on wire harnesses (such as cables, wires, connectors, etc.). It is widely used in automotive wire harnesses, home appliance cables, electronic equipment, and power engineering. It precisely heats the tubing to shrink, providing insulation, waterproofing, dustproofing, and abrasion resistance protection.

[0003] Chinese patent CN207105614U discloses a belt-type heat shrinking device, including an overall frame, a conveying mechanism, an upper hot air mechanism, and a lower hot air mechanism. Both the upper and lower hot air mechanisms include a heating component, an air supply box, and an air supply component disposed between the two side walls of the overall frame. This belt-type heat shrinking device has a reasonable structural design, facilitating the heat shrinking of heat shrink tubing and other components in automotive wiring harness production lines. By incorporating this device into automotive wiring harness production lines to perform heat shrinking of heat shrink tubing and other components, it improves the multi-dimensional heating effect and increases the working efficiency of automotive wiring harness production lines.

[0004] Chinese patent CN215039479U discloses a heat-drying device for wire harness heat shrink tubing, including a transmission mechanism, a heat-drying mechanism, a heat dissipation mechanism, and a collection mechanism. The transmission mechanism includes a first support frame, with electrically driven rollers evenly arranged on the top of the first support frame. This utility model heat-drying device can simultaneously heat and dissipate heat from heat shrink tubing on different types of wire harnesses and collect the wire harnesses separately, thus improving work efficiency.

[0005] Traditional wire harness heat shrink machines mostly use a heat shrink structure with a fixed air outlet width. The width of the hot air output channel is fixed and cannot be dynamically adjusted according to the width of the heat shrink area of ​​different wire harness specifications. This results in the hot air often covering the extra space indiscriminately, which not only causes a lot of heat waste and high energy consumption, but also easily leads to quality problems such as uneven heating of the heat shrink tube due to hot air diffusion. Utility Model Content

[0006] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that traditional wire harness heat shrink machines mostly adopt a heat shrink structure with a fixed air outlet width. The width of the hot air output channel is fixed and cannot be dynamically adjusted according to the width of the heat shrink tube of different specifications of wire harnesses. As a result, the hot air often covers the extra space indiscriminately, which not only causes a lot of heat waste and high energy consumption, but also easily leads to quality problems such as uneven heating of the heat shrink tube due to hot air diffusion.

[0007] To address the aforementioned problems, this utility model provides a wire harness heat shrink tubing heat shrinking machine, including a heat shrinking machine assembly. An adjustable air outlet assembly is fixedly connected to the middle of the inner end of the heat shrinking machine assembly, and a vision inspection assembly is fixedly connected to the front end of the heat shrinking machine assembly. An air outlet optimization assembly is connected to the lower end of the adjustable air outlet assembly. The heat shrinking machine assembly includes an electric conveyor belt, and an equipment frame is mounted on the upper end of the electric conveyor belt. An inclined guide platform is fixedly connected to the discharge end of the equipment frame. The adjustable air outlet assembly includes an air outlet cross frame, and a circular gear is fixedly connected to the middle of the upper end of the air outlet cross frame. A transverse rack is symmetrically meshed with the front and rear ends and left and right sides of the circular gear. A connecting vertical rod is fixedly connected to the lower end of the transverse rack, and a bottom movable retaining strip is fixedly connected to the lower end of the connecting vertical rod. An electric push rod is fixedly connected to the upper end of the air outlet cross frame.

[0008] In the above-mentioned wire harness heat shrink tubing heat shrink machine, the heat shrink machine component realizes automatic wire harness delivery, the vision detection component accurately captures the width data of the area covered by the heat shrink tubing, and only retains the air outlet channel that is suitable for the current wire harness, thereby reducing the air volume output while ensuring that the wind speed remains unchanged, thereby reducing the fan energy consumption.

[0009] As a further improvement of this application, a finished product storage platform is fixedly connected to the end of the inclined guide platform away from the electric conveyor belt, and multiple material blocking protrusions are fixedly connected to the upper side of the end of the finished product storage platform away from the inclined guide platform.

[0010] As a further improvement of this application, the output end of the electric actuator is connected to the transverse rack located at the rear, and the air outlet frame is connected to a fan via a duct.

[0011] As a further improvement of this application, the front and rear ends of the air outlet frame are symmetrically fixedly connected with transverse guide rails, and the transverse guide rails and the connecting vertical rods are slidably connected.

[0012] As another improvement of this application, the visual inspection component includes a linkage bar, and a width visual detector is fixedly connected to the lower middle part of the linkage bar.

[0013] As a further improvement to this application, the air outlet optimization component includes a perforated air outlet base plate fixedly connected to the lower end of the air outlet cross frame, the perforated air outlet base plate being located above the bottom movable clip.

[0014] As a further improvement to this application, an extended air guide vertical plate is fixedly connected to the lower end of the bottom movable clip, and the two extended air guide vertical plates are respectively fixedly connected to the two bottom movable clips at their close ends.

[0015] In summary, this solution enables automatic wire harness delivery using the heat shrink machine components, eliminating the need for manual handling and significantly reducing labor costs. The vision inspection component accurately captures the width data of the area covered by the heat shrink tubing, providing a reliable basis for the adjustable air outlet component. Combined with the meshing transmission of gears and racks and the guidance of the guide rail, the bottom movable clips flexibly adjust the spacing, retaining only the air outlet channel adapted to the current wire harness, avoiding indiscriminate coverage of excess space by hot air, reducing ineffective output and heat diffusion loss. By reducing the cross-sectional area of ​​the air outlet channel, the output air volume requirement of the fan is reduced, achieving targeted energy savings. Furthermore, the air outlet optimization component further enhances the heat shrinking effect. The multi-hole air outlet base plate evenly discharges hot air, and the extended air guide vertical plate moves synchronously with the bottom movable clips, effectively concentrating the hot air and preventing diffusion, ensuring that the hot air accurately acts on the heat shrink tubing area, adapting to the production of multiple specifications of wire harnesses.

[0025] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0026] First implementation method:

[0027] Figures 1-5 This invention discloses a heat shrinking machine for wire harness heat shrink tubing, including a heat shrinking machine assembly 1. An adjustable air outlet assembly 2 is fixedly connected to the middle of the inner end of the heat shrinking machine assembly 1. A vision inspection assembly 3 is fixedly connected to the front end of the heat shrinking machine assembly 1. An air outlet optimization assembly 4 is connected to the lower end of the adjustable air outlet assembly 2. The heat shrinking machine assembly 1 includes an electrically conductive conveyor belt 101 (optional model C-112M). An equipment frame 100 with a built-in PLC controller is mounted on the upper end of the electrically conductive conveyor belt 101. The discharge end of the equipment frame 100 is fixedly connected to... The inclined guide table 103 and the adjustable air outlet assembly 2 include an air outlet horizontal frame 200. A ring gear 201 is fixedly connected to the upper middle part of the air outlet horizontal frame 200. The front and rear ends and left and right sides of the ring gear 201 are symmetrically meshed with a transverse rack 202. A connecting vertical rod 207 is fixedly connected to the lower end of the transverse rack 202. A bottom movable retaining strip 204 is fixedly connected to the lower end of the connecting vertical rod 207. An electric push rod 203 is fixedly connected to the upper end of the air outlet horizontal frame 200. The optional model is the MINASA6 series.

[0028] A finished product storage platform 102 is fixedly connected to the end of the inclined guide platform 103 away from the electric conveyor belt 101. Multiple material-blocking protrusions 104 are fixedly connected to the upper side of the end of the finished product storage platform 102 away from the inclined guide platform 103. The output end of the electric push rod 203 is connected to the rear transverse rack 202. A blower 205 is externally connected to the exhaust frame 200 via a pipe. The optional model is an EBMPAPSTD3G310-GG05-01 centrifugal blower. The blower 205 has a built-in heating element. The front and rear ends of 0 are symmetrically fixedly connected with horizontal guide rails 206. The horizontal guide rails 206 and the connecting vertical rods 207 are slidably connected. The vision detection component 3 includes a linkage horizontal bar 300. A width vision detector 301 is fixedly connected to the middle of the lower end of the linkage horizontal bar 300. The optional model is the SC1000 series vision sensor. It receives reflected light through laser triangulation to calculate the width of the heat shrink tube coverage area, which serves as the basis for adjusting the air outlet width. The width vision detector (301) is signal-connected to the electric push rod (203).

[0029] Figures 1-5 During operation, the wire harness to be heat-shrinked is placed on the electrical conveyor belt 101 of the heat shrink machine assembly 1. The electrical conveyor belt 101 transports the wire harness along the inside of the equipment frame 100 to the heat shrinking work area. During this process, the vision inspection assembly 3 first detects the width of the wire harness about to enter the heat shrinking area. The linkage crossbar 300 fixes and supports the width vision detector 301. The width vision detector 301 captures the width data of the wire harness before heat shrinking in real time and feeds the data back to the adjustable air outlet assembly 2, providing a basis for adjusting the air outlet width. The adjustable air outlet assembly 2 starts adjustment based on the vision inspection results. The fan 205 delivers hot air to the air outlet crossbar 200 through a pipe. Simultaneously, the electrical push rod 203 is activated, and its output end pushes the rear transverse rack 202 to move laterally along the transverse guide rail 206. Since the transverse rack 202 meshes with the ring gear 201, the movement of the rear transverse rack 202 drives the ring gear 201. 01 rotates, thereby driving the front and rear transverse racks to move closer or further away in opposite directions. The transverse rack 202 drives the bottom movable clip 204 to move synchronously through the connecting vertical rod 207, realizing the adjustment of the distance between the two bottom movable clips 204, thereby adapting to the width of the heat shrink tubing coverage area. After heat shrinking, the wire harness continues to be transported by the electrical conveyor belt 101 to the inclined guide table 103, and slides into the finished product placement table 102 through the inclined guide table 103. The material blocking protrusion 104 at the end of the finished product placement table 102 prevents the wire harness from slipping, completing the entire heat shrinking operation process. Only the air outlet channel that adapts to the width of the current heat shrink tubing coverage area is retained, so that the hot air is concentrated on the area to be heat-shrinked, rather than indiscriminately covering the extra space, thereby reducing the ineffective output of hot air. At the same time, this dynamic adaptation avoids heat diffusion loss caused by excessive air outlet width, significantly reducing the continuous energy supply load of the fan 205, and achieving targeted energy saving.

[0030] Second implementation method:

[0031] Figures 6-7 A heat shrinking machine for wire harness heat shrink tubing is shown. The air outlet optimization component 4 includes a perforated air outlet base plate 400 fixedly connected to the lower end of the air outlet horizontal frame 200. The perforated air outlet base plate 400 is located above the bottom movable retaining strip 204. An extended air guide vertical plate 401 is fixedly connected to the lower end of the bottom movable retaining strip 204. The two extended air guide vertical plates 401 are respectively fixedly connected to the two bottom movable retaining strips 204 at their close ends. The air outlet optimization component 4, together with the adjustable air outlet component 2, enhances the heat shrinking effect: the perforated air outlet base plate 400 at the lower end of the air outlet horizontal frame 200 evenly discharges hot air, and the extended air guide vertical plate 401 at the lower end of the bottom movable retaining strip 204 further gathers the hot air, avoids hot air diffusion, and ensures that the hot air is accurately applied to the heat shrink tubing area of ​​the wire harness to achieve uniform heat shrinking.

[0032] In light of current practical needs, the above-described embodiments adopted in this application are not limited to this scope of protection. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
