Description

Technical Field

[0001] This utility model belongs to the field of cooling technology, and specifically relates to a cooling mechanism for a wire harness heat shrink tubing baking machine. Background Technology

[0002] A wire harness is an integrated component in an electrical system, consisting of multiple wires, connectors, terminals, and insulation materials combined according to specific functions. It is widely used in automotive, electronic equipment, aerospace, and industrial machinery industries. Its core function is to connect disparate electrical components (such as sensors, controllers, and actuators) into an ordered circuit network via wires, enabling signal transmission or power supply. To slow down the aging and corrosion of wire harnesses due to long-term use, extend their overall lifespan, and reduce the frequency of equipment maintenance and wire harness replacement, heat shrink tubing is typically used to cover the wire harness.

[0003] Currently, the operation of applying heat shrink tubing to wire harnesses mainly relies on heat shrink equipment. However, with the increasingly fast pace of production, the heat shrink equipment needs to be cooled quickly after heat shrinking the wire harness. The small fans used in the existing equipment cannot achieve the effect of rapid cooling, which affects production efficiency. Utility Model Content

[0004] In order to solve the problems existing in the prior art, this utility model aims to provide a cooling mechanism for a wire harness heat shrink tubing baking machine, so as to achieve rapid cooling of the wire harness after heat shrinking and improve production efficiency.

[0005] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0006] A cooling mechanism for a wire harness heat shrink tubing baking machine includes an upper air blowing assembly, a lower air blowing assembly, an air cooler, and a heat dissipation and exhaust assembly. The upper air blowing assembly and the lower air blowing assembly are respectively connected to the cold air output port of the air cooler through corresponding pipes. The upper air blowing assembly and the lower air blowing assembly are arranged vertically and opposite to each other, and the upper air blowing assembly and the lower air blowing assembly blow air to the heat-shrinked wire harness for cooling. The air intake of the heat dissipation and exhaust assembly is directly opposite the upper air blowing assembly, and the heat dissipation and exhaust assembly realizes the rapid extraction of the airflow blown by the upper air blowing assembly to the wire harness.

[0007] Furthermore, both the upper air blowing assembly and the lower air blowing assembly include an air supply block, an air cavity is formed inside the air supply block, the opening of the air cavity is located on the front end face of the air supply block, and a detachable baffle is provided at the opening of the air cavity, the baffle is provided with an air blowing port; and at least one set of air supply holes communicating with the air cavity are provided on the rear end face of the air supply block.

[0008] Furthermore, the air vents on the baffle are arranged in a matrix.

[0009] Furthermore, at least one set of air outlets communicating with the air cavity are respectively opened on the upper and lower end faces of the air supply block to which the upper blowing assembly belongs, and a clearance groove is opened around the outer opening of each air outlet, the clearance groove communicating with the front end face of the air supply block; and a fixing plate is respectively provided on the upper and lower end faces of the air supply block to which the upper blowing assembly belongs, and when the fixing plate is installed, an air outlet is formed between the fixing plate and the air supply block.

[0010] Furthermore, the upper and lower end faces of the air supply block to which the upper blowing assembly belongs are respectively provided with sealing grooves for accommodating sealing gaskets.

[0011] Furthermore, a connecting plate is provided at the lower end of the air supply block to which the downblowing assembly belongs, and the connecting plate has through holes.

[0012] Furthermore, the air cooler is a scroll tube cooler.

[0013] Furthermore, the heat dissipation and ventilation assembly includes an exhaust duct and an exhaust fan, with the exhaust fan located at the air outlet of the exhaust duct.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model achieves all-round air blowing cooling of the heat-shrinked wire harness by setting up an upper air blowing component and a lower air blowing component that are arranged vertically and relatively oppositely. At the same time, by cooperating with the vortex tube cooler, it greatly improves the cooling efficiency, effectively shortens the cooling time of the wire harness, and thus improves the overall production efficiency.

[0016] 2. The air blowing component of this utility model forms an air curtain on its upper and lower end faces during cooling, thereby isolating the heat source of the heat shrink tubing during baking and isolating the heat source emitted by the wire harness after the heat shrink tubing is baked between the air curtains; and in conjunction with the heat dissipation and exhaust component, the airflow blown towards the wire harness is quickly drawn away, accelerating the air flow around the wire harness, so that the heat can be dissipated more quickly, further improving the cooling effect of the wire harness.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] See Figure 1As shown, a cooling mechanism for a wire harness heat shrink tubing baking machine includes an upper air blowing assembly 1, a lower air blowing assembly 2, an air cooler 3, and a heat dissipation and exhaust assembly 4. During installation, the upper air blowing assembly 1 and the lower air blowing assembly 2 are connected to the cold air output port of the air cooler 3 through corresponding pipes. The upper air blowing assembly 1 and the lower air blowing assembly 2 are arranged vertically and opposite to each other, blowing air onto the heat-shrinked wire harness for cooling. The air intake of the heat dissipation and exhaust assembly 4 faces the upper air blowing assembly 1, and the heat dissipation and exhaust assembly 4 quickly removes the airflow blown by the upper air blowing assembly 1 onto the wire harness. In this embodiment, the air cooler 3 is a vortex tube cooler.

[0030] Further, see Figure 1 As shown, in this embodiment, the upper air blowing assembly 1 is positioned above the lower air blowing assembly 2. Therefore, during cooling, the wire harness, after the heat shrink tubing has been baked, is first cooled by the upper air blowing assembly 1 and then by the lower air blowing assembly 2, ensuring comprehensive cooling of the wire harness. In this embodiment, see... Figure 2-6 As shown, both the upper air blowing assembly 1 and the lower air blowing assembly 2 include an air supply block 11. An air cavity 111 is formed inside the air supply block 11. The opening of the air cavity 111 is located on the front end face of the air supply block 11. A detachable baffle 12 is provided at the opening of the air cavity 111. An air blowing port 121 is provided on the baffle 12. The air blowing ports 121 are arranged in a matrix on the baffle 12. Two sets of air supply holes 112 communicating with the air cavity 111 are provided on the rear end face of the air supply block 11. Of course, the number of sets of air supply holes 112 is only one embodiment and is not intended to limit the scope of this application. In actual settings, the number of sets can be set according to actual needs.

[0031] Further, see Figure 3As shown, in this embodiment, two sets of air outlets 113 communicating with the air cavity 111 are respectively opened on the upper and lower end faces of the air supply block 11 to which the upper air blowing assembly 1 belongs. However, it is not limited to two sets, and other sets can be set according to actual needs. A clearance groove 114 is opened around the outer opening of each air outlet 113, and the clearance groove 114 communicates with the front end face of the air supply block 11. A fixing plate 13 is respectively set on the upper and lower end faces of the air supply block 11 to which the upper air blowing assembly 1 belongs. When the fixing plate 13 is installed, an air outlet 115 is formed between the fixing plate 13 and the air supply block 11. During cooling, the cold air outlet of the air cooler 3 is connected to the upper air cavity 111 through a pipe. The air supply hole 112 in the air supply block 11 of the blower assembly 1 is connected. After being cooled by the air cooler 3, the air enters the air supply hole 112 through the pipe and is then sent into the air cavity 111 in the upper blower assembly 1. It is then blown out through the air outlet 121, thereby cooling the wire harness after the heat shrink tubing has been baked. At the same time, part of the air enters the air outlet 113 and passes through the clearance groove 114, and is finally blown out through the air outlet 115. This achieves the cooling of the wire harness after the heat shrink tubing has been baked, while also creating an air curtain effect at the upper and lower ends of the air supply block 11 of the upper blower assembly 1. This isolates the heat source of the heat shrink tubing from the air curtain and isolates the heat source emitted by the wire harness after the heat shrink tubing has been baked between the air curtains.

[0032] For further details, please refer to [link / reference]. Figure 3 As shown, the upper and lower end faces of the air supply block 11 of the upper air blowing assembly 1 are respectively provided with sealing grooves 116 for accommodating the sealing gasket 14. The sealing gasket 14 is tightly attached to the contact surface between the fixing plate 13 and the air supply block 11, which effectively enhances the sealing performance at the connection between the two, prevents cold air from leaking from the connection gap between the fixing plate 13 and the air supply block 11, and ensures that the cold air can be blown out through the air outlet 115 according to the predetermined path, so as to stably cool the wire harness after the heat shrink tubing is baked, while forming a reliable air curtain effect.

[0033] Further, see Figure 1 As shown, the heat dissipation and ventilation assembly 4 includes an exhaust pipe 41 and an exhaust fan 42. During installation, the air intake of the exhaust pipe 41 faces the upper air blowing assembly 1, while the exhaust fan 42 is located at the air outlet of the exhaust pipe 41. During cooling, under the action of the exhaust fan 42, the airflow blown by the upper air blowing assembly 1 towards the wire harness is quickly drawn away, thereby improving the cooling effect on the wire harness.

[0034] Further, see Figure 4-5As shown, a connecting plate 15 is provided at the lower end of the air supply block 11 to which the downblowing assembly 2 belongs. The connecting plate 15 has a through hole 151, which corresponds one-to-one with the air supply hole 112 in the air supply block 11 to which the downblowing assembly 2 belongs. After installation, the through hole 151 is connected to its corresponding air supply hole 112. During cooling, the cold air outlet of the air cooler 3 is connected to the through hole 151 through a pipe. After being cooled by the air cooler 3, the air enters the corresponding air supply hole 112 through the through hole 151 and is then sent into the air cavity 111 in the downblowing assembly 2. It is then blown out through the air outlet 121 to further cool the wire harness.

[0035] The working principle of this utility model is as follows:

[0036] See Figure 7 As shown in the figure (label A represents the mounting frame; label B represents the wire harness drive mechanism); during cooling, when the wire harness, after completing the heat shrink tubing baking process under the transmission of the wire harness drive mechanism, enters the upper air blowing assembly 1 area of ​​this cooling mechanism, the air blown from the air blowing port 121 and air outlet 115 of the upper air blowing assembly 1 blows towards the wire harness after the heat shrink tubing baking to cool it down, while the airflow blowing towards the wire harness is quickly drawn away by the heat dissipation exhaust assembly 4 to achieve rapid cooling of the wire harness; after the wire harness passes through the upper air blowing assembly 1 area, it enters the lower air blowing assembly 2 to achieve continuous cooling of the wire harness to ensure that the wire harness temperature drops below the minimum required temperature.

[0037] It should be noted that before use, the air inlet of the air cooler 3 must be connected to an external air supply device so that air can be supplied to the air cooler 3 through the external air supply device.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
