Technical Field

[0001] The utility model relates to the technical field of PI heating film production, in particular to a baking device for a PI heating film. Background Art

[0002] PI heating film is made of polyimide film as the outer insulator and metal foil and wire as the inner conductive heating element, which are heat-sealed at high temperature and high pressure. Polyimide film electric heating film has excellent insulation strength, excellent electrical strength, excellent thermal conductivity efficiency and excellent resistance stability, which makes it widely applicable to the heating field and can obtain a fairly high temperature control accuracy. In the production process of PI heating film, the positive and negative electrode sheets of the heating film need to be welded with connecting wires, and after welding, the welding points need to be encapsulated with adhesive. The adhesive encapsulation process dries relatively slowly and requires manual intervention.

[0003] However, the existing PI heating film baking device (a PI heating film baking device with application number 202223097542.4) has no fixing mechanism during the baking process because the PI heating film is relatively thin, so that the PI heating film moves or floats due to the heated airflow, affecting the baking processing efficiency of the baking device on the PI heating film.

The screw rod on the adjusting mechanism is installed between the two positioning mechanisms, so that the adjusting mechanism adjusts the positioning and fixing positions of the two positioning conveyor belts installed on the screw rod, and the positioning mechanism drives the positioning conveyor belt to position, press and fix the PI heating film placed on the conveyor belt;

[0007] Two heating components are vertically arranged in parallel and correspondingly disposed at the upper and lower ends of the baking oven, so that the heating components output convective drying airflow into the baking oven to bake the PI heating film placed on the conveyor belt up and down.

[0008] Furthermore, the positioning mechanism includes a telescopic drive member, a mounting plate and two guide rods, the two guide rods are fixedly installed on the wall of the baking box in parallel and at intervals, and the tops of the two guide rods are fixedly connected to a support plate, the support plate is mounted on the telescopic drive member, and the top of the mounting plate is fixedly connected to the output end of the telescopic drive member, and both ends of the mounting plate are movably mounted on the guide rods, so that the telescopic drive member drives the mounting plate to move up and down along the vertical direction of the guide rods.

[0009] Furthermore, the screw rod is rotatably installed between the two mounting plates, and a rotating driving member on the adjustment mechanism is horizontally fixedly installed on the side of the mounting plate, and the screw rod is fixedly connected to the output end of the rotating driving member so that the rotating driving member drives the screw rod to rotate.

[0010] Furthermore, two correspondingly arranged rollers are screwed on the screw rod, and a positioning conveyor belt is installed on the outer side of each roller, so that the rotating drive member drives the two rollers screwed on the screw rod to move relative to each other, thereby adjusting the positioning width of the positioning conveyor belts installed on the two rollers.

[0011] Furthermore, the positioning conveyor belt is rotatably installed on the outer sides of the two rollers, and the conveyor belt drives the positioning conveyor belt to rotate synchronously after being positioned and fixed.

[0012] Furthermore, the heating assembly includes a plurality of fans and heating tubes, wherein the plurality of fans are horizontally arranged in parallel and installed at intervals at the upper and lower ends of the baking oven, and a heating tube is installed at the bottom of the fan so that the fan can blow the airflow heated by the heating tube into the baking oven.

[0013] Furthermore, the heating tube is coiled in the inner cavity of the baking box, and the heating tube is electrically connected to the chassis.

[0014] In summary, the beneficial effects of this application are:

[0015] 1. By arranging a fixing component on the baking oven, the adjusting mechanism on the fixing component is started, so that the rotating driving member on the adjusting mechanism drives the screw to rotate, so that the two rollers screwed on the screw move relatively along the length direction of the screw, thereby adjusting the positioning width of the positioning conveyor belt installed on the roller, so that the fixing component can bake and position PI heating films of different sizes;

[0016] Second, by arranging a positioning mechanism on the fixed component, the mounting plate on the positioning mechanism moves along the vertical direction of the guide rod under the drive of the telescopic driving member, so that the positioning conveyor belt moves down to position and fix the PI heating film placed on the conveyor belt, so that when the conveyor belt rotates, the PI heating film abutted by the positioning conveyor belt is driven to move synchronously, preventing the PI heating film from floating due to the convection airflow in the baking box during the baking process, thereby improving the baking processing efficiency of the baking device for the PI heating film;
