Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing equipment, in particular to a heat shrink tube heating device and a baking device. Background Art

[0002] During the production of wire harnesses, various technical measures are often used to ensure protection and insulation. One common method is to place sealing sleeves over the terminals. These sleeves effectively protect the wire harness from environmental damage. However, their use is limited, primarily because they are typically only suitable for standard-sized terminals. When the terminals are complex or have unusual shapes, the sealing sleeves' application becomes limited, making them less effective in providing protection.

[0003] Another common practice is to use a hot air gun. This device heats air with an electric heating element and then blows the hot air toward the heat shrink tubing wrapped around the wiring harness, causing it to shrink and tightly wrap around the wiring harness, thereby achieving both protection and insulation. However, in practice, improper operation when using a handheld hot air gun can lead to uneven shrinkage of the tubing, compromising the overall sealing effect. Furthermore, manual operation is inefficient for large-scale cable processing tasks and cannot meet the efficiency demands of modern production. These issues are particularly prominent in large-scale production, necessitating the urgent need for more efficient and stable processes or equipment to improve production efficiency and ensure the reliability of the wiring harness.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] like Figures 1 to 7 The heat shrink tube heating device shown includes: a heating mechanism 1, specifically as Figure 1 As shown in the figure, there are multiple infrared heating tube groups 11 evenly distributed around the heating mechanism 1; wherein, the heating mechanism 1 is provided with an open port, and the heating end of the wire harness is placed into the heating mechanism 1 through the open port, and the multiple infrared heating tube groups 11 heat the heat shrink tube on the wire harness. We should understand that the heating mechanism 1 converts electrical energy into thermal energy, and the far infrared rays emitted by the multiple infrared heating tube groups 11 are irradiated onto the heat shrink tube on the wire harness, causing it to shrink and thus completing the protection of the wire harness; far infrared rays have the characteristics of strong penetrating power and high energy, so far infrared rays have a significant heating effect on objects, especially on heat shrinkable materials. As Figure 1 As shown, the wiring harness to be processed is placed in the heating mechanism 1, and a plurality of infrared heating tube groups 11 heat the heat shrink tubing on the wiring harness so that it shrinks evenly and then wraps the wiring harness. After completion, the wiring harness is taken out. During the heating process, we should also understand that the calculation formula for the shrinkage ratio of the heat shrink tubing is usually: shrinkage ratio = original diameter / diameter after shrinkage. For example, a heat shrink tubing with an original diameter of 10 mm shrinks to 2.5 mm after heating, and its shrinkage ratio is 10:2.5, that is, 4:1. When selecting a heat shrink tubing, it should be ensured that its original diameter is larger than the diameter of the protected object so that a tight wrapping layer can be formed after heating and shrinking. The utility model uses far-infrared technology to heat and shrink the heat shrink tubing, which can accurately adjust the temperature and ensure that the heat shrink tubing remains consistent during the shrinking process, thereby significantly improving the insulation and protection performance. It is also more suitable for application scenarios with strict temperature control requirements. It not only ensures the high quality of the product, but also adapts to the needs of mass production, greatly shortens the construction cycle, and improves overall efficiency.

[0030] In some embodiments of the present invention, the inner wall of the heating mechanism 1 is provided with mirrored stainless steel 12, and the outer wall of the heating mechanism 1 is provided with multi-layer protective sheet metal 13. Figure 1 and Figure 2 As shown, the mirrored stainless steel 12 has a high reflectivity and can effectively reflect the thermal radiation emitted by the infrared heating tube group 11, so that the heat is evenly distributed within the heating mechanism 1. Since stainless steel itself has excellent corrosion resistance, especially in high-temperature environments, this allows the heating mechanism 1 to maintain good physical properties and surface finish during long-term use and is not easily oxidized or corroded. Therefore, setting the mirrored stainless steel 12 on the inner wall of the heating mechanism 1 can significantly improve the performance of the device, ensure the uniformity and efficiency of the heating process, and also enhance the durability and ease of use of the device. The multi-layer protective sheet metal 13 forms an effective thermal barrier by combining multiple thin layers of metal plates. There may be air interlayers or insulating materials between each layer of protective sheet metal 13. This structure can effectively reduce the transfer of heat from the inside to the outside of the heating mechanism 1, ensuring a low outer wall temperature, thereby improving the thermal insulation performance and energy efficiency of the device. In addition, the multi-layer protective sheet metal 13 structure can combine different metal materials, significantly improving the mechanical strength and deformation resistance of the outer wall of the heating mechanism 1 while also enhancing the corrosion resistance of the outer wall.

[0031] Furthermore, the heating surfaces of the plurality of infrared heating tube groups 11 are provided with mesh protective covers 11a. Figure 1 The mesh protective cover 11a can effectively prevent operators or other objects from directly contacting the infrared heating tube group 11, avoiding burns or equipment damage caused by accidental contact. Moreover, the infrared heating tube group 11 is fragile, especially at high temperatures. The mesh protective cover 11a not only reduces the risk of damage to the infrared heating tube group 11, but also enhances the operational safety of the equipment.

[0032] In another aspect of the embodiment of the present invention, a baking device is provided, comprising the above-mentioned heat shrink tube heating device, and further comprising a wire rack 2, a movable carrier 3 and a plurality of workstations 4, wherein the wire rack 2 is arranged at the heating mechanism 1 and is used to place the wire harness, and the wire rack 2 is arranged on each of the plurality of workstations 4, and the movable carrier 3 is used to drive the heating mechanism 1 to move horizontally relative to the wire rack 2 and vertically on the same plane. Figure 3The wire rack 2 can be composed of a terminal fixing row and a heat shrink tubing fixing wire harness clamp row. The corresponding terminal fixing row and wire harness clamp row can be selected or adjusted for wire harnesses of different sizes. During operation, the wire harness to be processed is placed on the wire rack 2, and the mobile carrier 3 drives the heating mechanism 1 to move toward the wire rack 2. When the wire harness enters the heating mechanism 1, multiple infrared heating tube groups 11 heat the heat shrink tubing on the wire harness, causing it to shrink evenly and then wrap around the wire harness. After completion, the mobile carrier 3 drives the heating mechanism 1 to move away from the wire rack 2, and the wire harness can then be removed from the wire rack 2. The baking equipment can have multiple operating stations 4. During the specific operation process, the operator can first place the wire harness to be heated on a wire rack 2. At this time, the mobile carrier 3 drives the heating mechanism 1 to move toward this station 4 to heat the wire harness to be heated. During the heating process of the heating mechanism 1, the operator can place the wire harness to be heated on the wire rack 2 at another one or more other stations 4 or remove the heated wire harness. After the wire harness on the original station 4 is heated, the wire harness will be removed for the next operation. After the heating mechanism 1 at the original station 4 is heated, it can be moved to the next station 4 or the set position by the mobile carrier 3. The setting of multiple station 4 wire racks 2 improves production efficiency.

[0033] Specifically, the mobile carrier 3 includes a vertical drive assembly 32, the top of which has a first support plate 31 for mounting the heating mechanism 1, and the vertical drive assembly 32 is mounted on a second support plate 33. Figure 4 and Figure 5 As shown, a vertical drive assembly 32 is mounted on the second support plate 33 of the device. The upper end surface of the first support plate 31 at the top of the vertical drive assembly 32 is fixed to the heating mechanism 1. The vertical drive assembly 32 can drive the first support plate 31 to perform relative linear motion in the vertical direction of the horizontal plane, thereby achieving vertical movement of the heating mechanism 1. Through this structure, when the wire harness needs to be heated, the vertical drive assembly 32 can drive the heating mechanism 1 close to the wire rack 2. After heating is completed, the vertical drive assembly 32 drives the heating mechanism 1 away from the wire rack 2, thereby improving the operational flexibility of the device and the safety of the heating process.

[0034] Preferably, the vertical drive assembly 32 includes a first drive motor 32a and a first screw rod 32b driven to rotate by the first drive motor 32a, and a first nut 31a adapted to the first screw rod 32b is provided at the bottom of the first support plate 31. Figures 4 to 6As shown, the first drive motor 32a is the core power source of the vertical drive assembly 32, responsible for providing rotational power to enable the first screw rod 32b to rotate under the drive of the motor. The first nut 31a at the bottom of the first support plate 31 is adapted to the first screw rod 32b. When the first screw rod 32b rotates, the first nut 31a moves along the axial direction of the first screw rod 32b, thereby achieving vertical movement of the heating mechanism 1. The first drive motor 32a ensures the accuracy and controllability of the device, achieving precise movement of the heating mechanism 1.

[0035] Furthermore, a plurality of first sliders 31b are provided at the bottom of the first support plate 31, and a first slide rail 33a adapted to the plurality of first sliders 31b is provided on the second support plate 33. Figure 4 and Figure 5 The first slide rail 33a provides a precise linear guide path and can also effectively prevent the first support plate 31 from lateral deviation or shaking during vertical movement, ensuring that the movement of the heating mechanism 1 is not disturbed by the outside world; the setting of several first sliders 31b can evenly distribute the weight of the heating mechanism 1 on multiple contact points, reduce single-point stress concentration, and improve the bearing capacity of the overall structure; in addition, the setting of the first slider 31b and the second slide rail 35a reduces the friction of the equipment during operation, and also reduces the vibration and noise of the equipment during movement, which not only improves the operating stability of the equipment, but also improves the comfort of the working environment.

[0036] On the basis of the above embodiment, the mobile vehicle 3 further includes a transverse driving component 34, the top of the transverse driving component 34 is connected to the second support plate 33, and the transverse driving component 34 is installed on the third support plate 35. Figure 4 and Figure 7 As shown, the relative installation structure of the transverse drive assembly 34, the second drive motor 34a, the second screw rod 34b and the second nut 33b is the same as the above principle, which will not be elaborated here. The setting of the transverse drive assembly 34 allows the second support plate 33 to make relative transverse movement on the horizontal plane, indirectly driving the relative transverse movement of the heating mechanism 1, which is used in conjunction with the corresponding wire rack 2. After the heating of the wire harness on a single wire rack 2 is completed, the longitudinal drive assembly drives the heating mechanism 1 away from the wire rack 2 at this location, and then the transverse drive assembly 34 moves the heating mechanism 1 to another wire rack 2 to be heated. At this time, the longitudinal drive assembly is close to the other wire rack 2 to be heated and works on it. In this process, the wire harness on the original wire rack 2 can be removed and a new batch of wire harnesses to be heated can be installed. This method greatly improves production efficiency and is more suitable for the needs of mass production. It shortens the construction period while also improving overall efficiency.

[0037] Specifically, the transverse drive assembly 34 includes a second drive motor 34a and a second screw rod 34b driven to rotate by the second drive motor 34a, and a second nut 33b adapted to the second screw rod 34b is provided at the bottom of the second support plate 33. Figure 7 As shown, the relative installation structure and beneficial effects of the transverse drive assembly 34, the second drive motor 34a, the second screw rod 34b and the second nut 33b are the same as those described above and will not be elaborated here.

[0038] Preferably, a plurality of second sliders 33c are provided at the bottom of the second support plate 33, and a second slide rail 35a adapted to the plurality of second sliders 33c is provided on the three support plates. Figure 7 The relative installation structure and beneficial effects of the plurality of second sliders 33c on the second support plate 33 and the second slide rails 35a on the three support plates are the same as those described above and will not be elaborated on here.

The above-described embodiments and the specification are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
