DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is described in detail below in conjunction with the accompanying drawings. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present application.

[0026] The present application provides a carbon fiber prepreg heating device, comprising:

[0027] Adsorption platform 1;

[0028] A mounting frame, the mounting frame is arranged on one side of the adsorption platform 1, and a guide assembly, a heating assembly, a pressure roller assembly, and a winding assembly are arranged on the mounting frame and above the adsorption platform 1;

[0029] After being led out from the guide assembly, the material strip 2 passes through the heating assembly and the pressing roller assembly in sequence. The heating assembly is used to heat the release paper and the carbon fiber prepreg in the material strip 2. The pressing roller assembly is used to lay the carbon fiber prepreg flat on the adsorption platform 1. The winding assembly is used to collect the release paper after being separated from the carbon fiber prepreg.

[0030] A first temperature sensor 3, which is arranged on the mounting frame at a position relatively close to the inlet end of the heating component, with its detection end facing the material strip 2, and is used to detect the feed temperature of the material strip 2 before it enters the heating component;

[0031] A controller, wherein the controller signal is connected to the first temperature sensor 3, and is used to receive the feed temperature measured by the first temperature sensor 3, and control the heating temperature of the heating component according to the feed temperature.

[0032] Specifically, in this embodiment, Figure 1As shown, the embodiment of the present application provides a carbon fiber prepreg heating device, the carbon fiber prepreg heating device comprises an adsorption platform 1, a mounting frame is provided on one side of the adsorption platform 1, a guide component, a heating component, a pressure roller component and a winding component are provided on the mounting frame, the guide component, the heating component, the pressure roller component and the winding component are all located above the adsorption platform 1, and a material belt 2 is guided out from the guide component and passes through the heating component and the pressure roller component in sequence, the material belt 2 comprises carbon fiber prepreg, and release paper and an isolation film provided on both sides of the carbon fiber prepreg, the heating component is used to The material strip 2 led out by the guide assembly is heated so that the release paper is separated from the carbon fiber prepreg, and the isolation film is taken away during the heating process. The device for taking away the separation film belongs to the prior art and will not be repeated here. After being heated by the heating component, the material strip 2 enters the pressing roller assembly and is squeezed by the pressing roller assembly, so that the carbon fiber prepreg is spread flat on the adsorption platform 1 for the subsequent process. The release paper is taken up by the winding assembly. During the whole movement process, the adsorption platform 1 is constantly moving, so it can drive the entire material strip 2 to be continuously heated;

[0033] A first temperature sensor 3 is also provided on the mounting frame at a position relatively close to the inlet end of the heating component. The first temperature sensor 3 has a detection end, and the detection end faces the material belt 2. The first temperature sensor 3 is used to detect the feed temperature of the material belt 2 before it enters the heating component. The controller is also connected to the first temperature sensor 3 signal. After receiving the feed temperature measured by the first temperature sensor 3, the controller will judge the feed temperature. When it is judged that the feed temperature is lower than the temperature threshold, the heating component will be controlled to increase the temperature. When it is judged that the feed temperature is higher than the temperature threshold, the heating component will be controlled to reduce the temperature.

[0034] The reason why the feed temperature is lower than the temperature threshold may be due to a significant drop in ambient temperature. If the heating component is not controlled to increase the temperature, the material strip 2 will not be able to reach the temperature threshold, resulting in poor separation effect; the reason why the feed temperature is higher than the temperature threshold may be due to a significant increase in ambient temperature. If the heating component is not controlled to lower the temperature, the temperature of the material strip 2 will be too high, causing the carbon fiber prepreg to be damaged after separation, or its own performance to change.

[0035] During use, after the material strip comes out of the guide component, it enters the heating component for heating. During the process of entering the heating component, the first temperature sensor detects the temperature of the material strip in real time and sends the detected temperature to the controller. After receiving the feed temperature measured by the first temperature sensor, the controller will control the heating temperature of the heating component to increase or decrease, so that the prepreg and the release paper are more easily separated without being damaged. The carbon fiber prepreg heated by the heating component is squeezed by the pressure roller assembly and remains on the adsorption platform, and the release paper is collected by the winding assembly. The carbon fiber prepreg on the adsorption platform can enter the next process. The present application is provided with a first temperature sensor, which can detect the temperature of the material strip in real time and send the detected temperature to the controller. After receiving the temperature, the controller will control the heating temperature of the heating component to increase or decrease according to the feed temperature. In this way, it is more conducive to the separation of the carbon fiber prepreg and the release paper.

[0036] Furthermore, a second temperature sensor 4 is provided on the mounting frame at a position relatively close to the outlet end of the heating component, and the detection end of the second temperature sensor 4 faces the material belt 2, and is used to detect the outlet temperature of the material after the heating of the heating component is completed;

[0037] The second temperature sensor 4 signal is connected to the controller, which is used to receive the discharge temperature measured by the second temperature sensor 4 and control the heating temperature of the heating component according to the discharge temperature.

The second temperature sensor 4 has a detection end, and the detection end faces the material strip 2. After the material strip 2 comes out from the inside of the heating component, the second temperature sensor 4 will detect in real time the temperature of the material strip 2 that has been heated from the inside of the heating component, that is, the discharge temperature. After receiving the discharge temperature, the controller will judge the discharge temperature. When the controller judges that the discharge temperature is lower than the temperature threshold, the controller will control the heating component to increase the temperature so that the carbon fiber prepreg and the release paper are easier to separate. When the controller judges that the discharge temperature is higher than the temperature threshold, the controller will control the heating group to lower the temperature so as to avoid damage to the carbon fiber prepreg after separation, or changes in its physical and chemical properties.
