Description

Technical Field

[0001] This utility model relates to the field of hot melt adhesive film hot pressing technology, and in particular to an FFC hot melt adhesive film hot pressing device. Background Technology

[0002] Flexible flat cables (FFCs) are widely used in consumer electronics, automotive electronics, and medical equipment due to their advantages such as thinness, flexibility, and high-density cabling. As electronic products become increasingly lightweight and miniaturized, the connection reliability of FFCs has become a key challenge. Hot melt adhesive film hot pressing technology, with its high efficiency, environmental friendliness, and high bonding strength, has become the mainstream technology for FFC packaging. Therefore, it is necessary to design an FFC hot melt adhesive film hot pressing device.

[0003] To address this, patent CN216683662U discloses a hot-pressing composite device for processing carbon fiber electrothermal film. The device includes a base, a heating device located at the top of the base near its left edge, an inlet on the left side of the heating device, an outlet on the right side of the heating device, a lifting plate above the heating device, three evenly distributed hot-pressing components at the bottom of the lifting plate, and a winding roller on the right side of the outlet. This invention, by incorporating the heating device and hot-pressing components, allows for uniform heating of the hot-melt adhesive film via the heating plate, ensuring consistent melting across different parts of the film and guaranteeing effective adhesion. The three hot-pressing components enable multiple hot-pressing composites of the hot-melt adhesive film, thereby improving the adhesion between the hot-melt adhesive film and carbon fiber and insulating materials, preventing delamination between the carbon fiber and insulating materials, and facilitating the use of the carbon fiber electrothermal film.

[0004] Although the hot melt adhesive film hot pressing composite device for processing carbon fiber electric heating film mentioned above can avoid delamination between carbon fiber and insulating material during use, making it convenient for the use of carbon fiber electric heating film, it is inconvenient to deal with the odor generated during the hot pressing process and it is inconvenient to quickly cool down the product after hot pressing. Therefore, it is necessary to design an FFC hot melt adhesive film hot pressing device. Utility Model Content

[0005] The purpose of this invention is to provide an FFC hot melt adhesive film hot pressing device to solve the shortcomings of existing hot melt adhesive film hot pressing devices, which are inconvenient to deal with the odor generated during the hot pressing process and inconvenient to quickly cool down the product after hot pressing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an FFC hot melt adhesive film hot pressing device, including a base;

[0007] A protective component is fixed to the top of the base, and cooling and deodorizing structures are fixed to both sides of the bottom of the protective component.

[0008] The cooling and deodorizing structure includes an air duct fixed to one side of the bottom of the protective component, a suction fan fixed to one end of the air duct, a filter frame slidably connected to the top of the air duct, a deodorizing agent fixed on the inner wall of the filter frame, and a blower fixed to the bottom of the protective component away from the suction fan. The top of the filter frame extends to the outside of the air duct and is fixedly connected to a top plate.

[0009] A pressing structure is fixed above the base, a heating structure is fixed at the bottom of the pressing structure, and a positioning seat is fixed at the top of the base.

[0010] Furthermore, the protective component includes a protective frame, side grooves, and a door panel. The protective frame is fixed to the top of the base, and side grooves are provided on both sides of the bottom of the protective frame. A door panel is evenly hinged to one side of the protective frame.

[0011] Furthermore, the deodorizing agent is an activated carbon plate, and small holes are evenly distributed inside the deodorizing agent.

[0012] Furthermore, the pressing structure includes a top frame, a hydraulic rod, a guide rod, and a horizontal plate. The top frame is positioned above the base, and a hydraulic rod is fixed to the bottom end of the top frame. A horizontal plate is fixed to the bottom end of the hydraulic rod, and guide rods are slidably connected to the corner positions inside the horizontal plate.

[0013] Furthermore, the top end of the guide rod is fixedly connected to the bottom end of the top frame, and the bottom end of the guide rod is fixedly connected to the top end of the base.

[0014] Furthermore, the heating structure includes a heating box, a heating wire, a pressure plate, a pressure sensor, and a temperature sensor. The heating box is fixed to the bottom of the horizontal plate. The heating wire is fixedly installed inside the heating box. The pressure plate is evenly fixed to the bottom of the heating box. The pressure sensor is fixed to the middle position of the bottom of the pressure plate. Temperature sensors are fixed to both sides of the bottom of the pressure plate.

[0015] Furthermore, both the pressure sensor and the temperature sensor have a microcontroller fixedly installed inside. The output end of the pressure sensor and the input end of the hydraulic rod are electrically connected through the microcontroller, and the output end of the temperature sensor and the input end of the heating wire are electrically connected through the microcontroller.

[0016] The advantages of the FFC hot melt adhesive film hot pressing device provided by this utility model are as follows:

[0017] By incorporating a cooling and deodorizing structure, the device adsorbs volatile organic compounds generated during the hot pressing process, such as esters or aldehydes from the decomposition of the adhesive film, thereby improving the working environment and meeting environmental protection requirements. The suction fan and blower work together to form forced convection heat dissipation, shortening the cooling time and improving production efficiency. The filter frame can be slidably disassembled for easy replacement of the deodorizing agent, reducing maintenance costs. This device enables convenient cooling of products and easy removal of odors, improving the convenience and applicability of the FFC hot melt adhesive film hot pressing device.

[0018] By incorporating a downward pressing structure, the hydraulic rod provides stable downward pressure, ensuring uniform contact between the adhesive film and the FFC interface, avoiding incomplete welding or air bubbles. The sliding fit between the guide rod and the horizontal plate prevents the pressure plate from tilting, ensuring that the pressure is applied vertically. This enables the device to have a function of easy and stable downward pressing, improving the convenience and stability of the FFC hot melt adhesive film hot pressing device during use.

[0019] By incorporating a heating structure with evenly distributed heating wires, combined with a temperature sensor, temperature monitoring and control are easily achieved, adapting to the melting point differences of various adhesive films. The pressure plate uses a high thermal conductivity material, such as aluminum alloy, to quickly transfer heat to the adhesive film, shortening the melting time. The temperature sensor monitors in real time, and in case of overheating, the microcontroller automatically cuts off the power to the heating wires to prevent overheating damage to the FFC. This device enables convenient hot pressing, improving the ease of use and work efficiency of the FFC hot melt adhesive film hot pressing device. Attached Figure Description

[0029] When the external power supply is connected and the suction fan 31 is started, the suction fan 31 can draw the odorous air inside the protective frame 21 into the filter frame 33 through the air duct 32.

The filter frame 33 and the air duct 32 are slidably connected, which can facilitate quick disassembly and maintenance.
