Description

Technical Field

[0001] This utility model relates to the field of automotive interior manufacturing technology, and more specifically, to a multi-directional heating device for automotive interior covering. Background Technology

[0002] In the current automotive interior parts (such as dashboards and door panels) wrapping process, the activation of the adhesive relies on manual hand-held hot air guns or fixed infrared lamps for heating.

[0003] In the production of traditional automotive interior parts covering molds, hot air guns or infrared lamps are usually used to heat and activate the viscosity of the adhesive. Complex curved surfaces are prone to local overheating (leading to carbonization of the adhesive layer) or underheating (insufficient adhesion), causing blistering and delamination. Workers need to manually adjust the heating angle, and the processing time for a single part can be as long as 3-5 minutes, which depends on the operator's experience. High temperature and close-range operation can easily cause burns, and human fatigue can easily lead to accidents.

[0004] The industry urgently needs an automated, multi-directional controllable heating solution to address the aforementioned issues. Utility Model Content

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0023] According to an embodiment of the present invention, a multi-directional heating device for automotive interior covering is provided.

[0024] Please refer to the instruction manual appendix. Figure 1-4 According to an embodiment of the present utility model, a multi-directional heating device for automotive interior covering includes a frame 1, on which a transfer mechanism 2 and a heating mechanism are provided. The heating mechanism includes a blower 3, a hot air generator 4, an air distribution component, and a temperature sensor 8. The air distribution component includes a heat-resistant hose 5, a hot air pipe 6, and a hot air chamber block 7.

[0025] Hot air flow channel construction:

[0026] Blower 3 delivers ambient temperature air to heater 4 through multi-port pipe, heating it to the set temperature (150-180℃);

[0027] Hot air is diverted through heat-resistant hose 5 (temperature resistance > 250℃) to multiple hot air pipes 6, and finally introduced into hot air chamber block 7;

[0028] Hot air chamber block optimized design:

[0029] Hot air chamber block 7 adapts to the complex contours of upper trim panel frame 9 (see...) Figure 1 Its dual exhaust vents are tilted at 15° (upper row) and 45° (lower row) respectively to ensure that the airflow covers the recessed area;

[0030] Coordinated control of transfer mechanism:

[0031] The transfer mechanism 2 drives the heating mechanism to move along the X / Y / Z axes, so that the hot air chamber block 7 maintains a constant distance (20-30mm) from the curved surface of the interior parts, thus avoiding local overheating.

[0032] In one embodiment, please refer to the appendix to the specification. Figure 1-4 As a further embodiment of this utility model, the blower 3 is disposed outside the frame 1, and the blower 3 and the hot air heater 4 are connected by a multi-port pipe.

[0033] In one embodiment, please refer to the appendix to the specification. Figure 1-4 As a further embodiment of this utility model, the hot air chamber block 7 is provided with two rows of air outlets facing different directions.

[0034] In one embodiment, please refer to the appendix to the specification. Figure 1-4 As a further embodiment of this utility model, the upper end of the hot air cavity block 7 is provided with an upper decorative panel frame 9.

[0035] In one embodiment, please refer to the appendix to the specification. Figure 1-4 As a further embodiment of this utility model, one end of the heat-resistant hose 5 is fixedly connected to the hot air blower 4, and the other end of the heat-resistant hose 5 is fixedly connected to the hot air pipe 6.

[0036] In one embodiment, please refer to the appendix to the specification. Figure 1-4 As a further embodiment of this utility model, the temperature sensor 8 is disposed at the air outlet of the hot air chamber block 7, and the temperature sensor 8 is electrically connected to the hot air blower 4.

[0037] A multi-directional heating device for automotive interior trim includes a transfer mechanism and a heating mechanism. The transfer mechanism is responsible for the vertical, tilting, or horizontal movement of the heating element. The working position is in the heating state, while the non-working position must avoid other functional components. The heating mechanism includes a blower, a hot air generator, an air distribution component, and a temperature sensor, connected in series or parallel via flexible hoses of different specifications. The blower provides power and delivers air to the hot air generator. After the air is heated to a specified temperature by the hot air generator, it is sent to the air distribution component. The air distribution component includes, but is not limited to, hot air ducts and hot air chambers. The curvature of the hot air ducts follows the contour of the product's frame at equal intervals, and single or multiple rows of small air ducts are evenly distributed on them. The hot air chambers are suitable for applications with narrow products and complex shapes (where other structures limit the space available for the heating element). Their shape can have multiple angular surfaces, each with evenly distributed air outlets. The temperature sensor and the hot air generator form a temperature control closed loop, ensuring stable heating.

[0038] Positioning stage: The transfer mechanism 2 moves the hot air chamber block 7 directly above the interior trim covering area;

[0039] Heating stage: Blower 3 starts, hot air blower 4 heats up to the set value, and the heat flows through the air distribution component to cover the target curved surface;

[0040] Temperature sensor 8 monitors the air temperature in real time, and triggers power adjustment of heater 4 when the temperature exceeds the tolerance.

[0041] Avoidance phase: After heating is completed, the transfer mechanism 2 will move the heating component away from the working area to avoid interfering with subsequent processes.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
