[0002] In the field of wire harness production, the wires and sleeves that make up the wire harness are typically insulated and sealed using a heat-shrink process. The conventional method for fixing the sleeve to the wire harness involves first slipping the sleeve onto the harness and then heating it with a hot air gun, causing the sleeve to shrink and tightly wrap around the surface of the wire harness. Existing heat-shrink devices for wire harnesses have the following problems: The current hot air gun heating method requires the operator to hold the heating device steadily and maintain a consistent distance and angle between the heating source and the heat-shrink tubing, making operation difficult, resulting in low heating efficiency, and making it impossible to stably control heating and cooling times, thus increasing the product defect rate.

Detailed Implementation

[0024] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Please refer to Figure 1This utility model provides a hot air type wire harness heat shrinking device 100, including a frame 10, a movable module 20, and a control unit 30 for controlling a heating unit 40 and a movable module 20. Both the movable module 20 and the control unit 30 are placed on the frame 10. Specifically, the control unit 30 is prior art and will not be described in detail in this embodiment. The output end of the movable module 20 is provided with a support frame 21, on which the heating unit 40 is mounted. The heating unit 40 is connected to an air source, and the output end of the heating unit 40 is connected to an air guide assembly 50. The movable module 20 is used to drive the air guide assembly 50 to move to correspond with the wire harness sleeve. Specifically, the mobile module 20 includes a telescopic cylinder 22 and a frame 23 for housing the telescopic cylinder 22. The frame 23 is tilted on the frame 10 via multiple support members of different heights. The support members include uprights 12 mounted on the frame 10 and a circular shaft 13 rotatably mounted on the uprights 12. The circular shaft 13 is fixedly connected to the frame 23. The angle of the frame 23 relative to the uprights 12 is adjusted via the circular shaft 13 and then fixed with bolts. The tilt angle of the frame 23 is determined by the height at which the wiring harness is placed. Simultaneously, the tilted arrangement of the frame 23 facilitates the mobile module 20 in driving the air guide assembly 50 closer to the wiring harness.

[0026] More specifically, in this embodiment, during the heat shrinking of the wire harness sleeve, the wire harness is clamped by a clamp, and the clamp is positioned at the lower end of the air guide assembly 50. The type of clamp is not limited in this embodiment.

[0027] Please refer to Figure 4 and Figure 5 The air guiding assembly 50 includes a support shell 51 connected to the heating unit 40, a first air guiding cavity 52 and a second air guiding cavity 53 rotatably connected to the support shell 51, and a drive module 54 for driving the second air guiding cavity 53 to rotate. Both the first air guiding cavity 52 and the second air guiding cavity 53 are connected to the heating unit 40. Each of the first air guiding cavity 52 and the second air guiding cavity 53 has a half-cavity 521. The two half-cavities 521 are closed to form a complete air guiding cavity 522. The complete air guiding cavity 522 has several through holes 5221, which are evenly distributed on the cavity wall of the complete air guiding cavity 522 and are connected to both the first air guiding cavity 52 and the second air guiding cavity 53. The through holes 5221 are also connected to the heating unit 40. For ease of identification, only some of the through holes 5221 are shown in the figure. The drive module 54 is used to drive the second air guide cavity 53 to rotate so that it cooperates with the first air guide cavity 52 to surround the wire harness sleeve, and so that the wire harness sleeve is located at the center of the complete air guide cavity 522.

[0028] By configuring a first air guide cavity 52 and a second air guide cavity 53 connected to the heating unit 40, during the heat shrinking of the wire harness sleeve, the moving module 20 drives the first air guide cavity 52 and the second air guide cavity 53 to move close to the wire harness sleeve. Simultaneously, the driving module 54 drives the second air guide cavity 53 to rotate, thus surrounding the wire harness sleeve. Ultimately, the air guide half-cavities 521 on the first air guide cavity 52 and the second air guide cavity 53 close to form a complete air guide cavity 522. The heating unit 40 is activated to heat the external air supplied by the air source and introduces the heated air into the first air guide cavity 52 and the second air guide cavity 53. The heated air is then introduced into the complete air guide cavity 522 through the through hole 5221, providing 360-degree circumferential heating to the wire harness sleeve. This reduces the difficulty of operation, improves heating efficiency, enables stable control of heating and cooling times, and increases the stability of heat shrinking.

[0029] For further details, please refer to Figure 5 Both the first air guide cavity 52 and the second air guide cavity 53 are provided with air guide plates 523. The air guide plates 523 are inclined, with one end of the air guide plate 523 closer to the heating unit 40 than the other end of the air guide plate 523 further away from the heating unit 40, which is closer to the central axis of the complete air guide cavity 522. The air supplied by the air source is heated by the heating unit 40 and then introduced into the first air guide cavity 52 and the second air guide cavity 53. When the air is introduced into the first air guide cavity 52 and the second air guide cavity 53, the air guide plates 523 guide the air, making it easier for the air to diffuse into the through hole 5221 in a direction away from the central axis between the first air guide cavity 52 and the second air guide cavity 53.

[0030] For further details, please refer to Figure 5 and Figure 6 The first air guide cavity 52 and the second air guide cavity 53 are both provided with a first rotating plate 524. The support shell 51 is provided with a second rotating plate 511 that is interposed with the first rotating plate 524. The first rotating plate 524 and the second rotating plate 511 are both provided with fixing holes 5111. The air guide assembly 50 also includes a fixing member 55, which passes through the fixing holes 5111 of the first rotating plate 524 and the fixing holes 5111 of the second rotating plate 511.

[0031] Specifically, the air guide cavity 521 is a semi-circular hole, and the complete air guide cavity 522 is a circular hole. The width of the first air guide cavity 52 and the second air guide cavity 53 are adapted to the length of the sleeve on the wire harness, and the aperture of the complete air guide cavity 522 is adapted to the diameter of the wire harness sleeve.

[0032] For further details, please refer to Figure 5 and Figure 6 The fixing member 55 includes a fixing rod 551 and a limiting ring 552. The fixing rod 551 passes through the fixing hole 5111 of the first rotating plate 524 and the fixing hole 5111 of the second rotating plate 511. The limiting ring 552 limits the fixing rod 551.

[0033] When it is necessary to replace the first air guide cavity 52 and the second air guide cavity 53 with different specifications, the connection between the first air guide cavity 52, the second air guide cavity 53 and the support shell 51 can be released by pulling the fastener 55 out of the fastening hole 5111. When installing the first air guide cavity 52 and the second air guide cavity 53, the first rotating plate 524 on the first air guide cavity 52 and the second air guide cavity 53 are respectively overlapped with the second rotating plate 511 on the support shell 51, so that the fastening holes 5111 on the first rotating plate 524 and the second rotating plate 511 coincide. Then, the fastening rod 551 is passed through the fastening holes 5111 on the first rotating plate 524 and the second rotating plate 511 at the same time to fix the first air guide cavity 52 and the second air guide cavity 53.

[0034] It is understandable that the different specifications of the first air guide cavity 52 and the second air guide cavity 53 refer to the different apertures of the air guide half cavity 521 of the first air guide cavity 52 and the second air guide cavity 53, as well as the different widths of the first air guide cavity 52 and the second air guide cavity 53. The dimensions of the connection between the first air guide cavity 52, the second air guide cavity 53 and the support shell 51 remain unchanged.

[0035] For further details, please refer to Figure 6 The drive module 54 includes a drive cylinder 541 and a hook 542 disposed at the output end of the drive cylinder 541. The second air guide cavity 53 is provided with a locking part 531 corresponding to the hook 542. The hook 542 hooks the locking part 531. The drive cylinder 541 is used to drive the hook 542 to rotate the second air guide cavity 53 relative to the first air guide cavity 52 until it cooperates with the first air guide cavity 52 to surround the wire harness, and so that the wire harness is located at the center of the complete air guide cavity 522. It can be understood that, in order to facilitate the rotation of the second air guide cavity 53, the hook 542 and the locking part 531 are not completely fitted. When the first air guide cavity 52 and the second air guide cavity 53 surround the wire harness, the wire harness sleeve is located at the center of the complete air guide cavity 522, that is, the wire harness sleeve and the complete air guide cavity 522 are concentrically arranged.

[0036] After the moving module 20 drives the first air guide cavity 52 and the second air guide cavity 53 to move close to the wire harness, the driving cylinder 541 drives the hook 542 to pull the second air guide cavity 53 to move backward, thereby causing the second air guide cavity 53 to rotate away from the first air guide cavity 52, thereby releasing the enclosure of the wire harness sleeve.

[0037] Please refer to Figure 5The heating unit 40 includes a heating element and a housing 42 disposed outside the heating element. The heating element is used to heat the air supplied by the air source. Specifically, the heating element is a resistance heating core, and the air source is an air pump. Neither the air source nor the heating element is shown in the figure. Furthermore, the heating unit 40 also includes a cooling fan 43 disposed on the housing 42, and the cooling fan 43 is connected to the inside of the housing 42. The cooling fan 43 is provided to dissipate heat from the inside of the housing 42, preventing the heating element from being damaged due to excessive temperature of the housing 42.

[0038] For further details, please refer to Figure 6 The heating unit 40 also includes a temperature probe 44, which extends between the first air guide cavity 52 and the second air guide cavity 53. The temperature probe 44 is used to detect the temperature at the output end of the heating unit 40. Specifically, in this embodiment, the temperature probe 44 is mounted on the support frame 21.

[0039] Please refer to Figure 3 The hot air type wire harness heat shrinking device 100 also includes a cold air component 60 disposed at the air guide assembly 50. The cold air component 60 includes at least one cold air duct 61, which is oriented towards the wire harness and is connected to an air source. It is understood that the air source connected to the cold air duct 61 can be an air pump or an air pump connected to a refrigeration unit. The air output from the corresponding cold air duct 61 can be room temperature air or low temperature air.

[0040] After the heating unit 40 heats the sleeves on the wire harness, it introduces room temperature or low temperature air into the wire harness through the cold air duct 61 to cool the wire harness sleeves.

[0041] Optional, please refer to Figure 2 In some other embodiments, the hot air type wire harness heat shrinking device 100 further includes a calibration component 70. The calibration component 70 includes a mounting plate 71 and a temperature sensor 72 connected to the mounting plate 71. The mounting plate 71 is disposed on the support frame 21. The temperature sensor 72 and the complete air guide cavity 522 are concentrically arranged. The temperature sensor 72 is used to detect the temperature of the hot air inside the complete air guide cavity 522. It is understood that the calibration component 70 only operates when the wire harness is not being heat-shrunk. When the wire harness is being heat-shrunk, in order to avoid the temperature sensor 72 affecting the heat shrinking of the wire harness, the calibration component 70 is removed from the support frame 21.
