[0099] It should be explained that the preparation instruction is an instruction used to control the coordinated work of various devices and systems in the automated preparation process. Modified polypropylene film refers to a special film obtained by modifying ordinary polypropylene film, which is used to manufacture capacitors for high-frequency applications.
[0100] Exemplarily, a precision balance is selected, and the precision balance is placed on a stable table. The precision balance is started, and a set of 100-gram standard weights is selected. The 100-gram standard weights are gently placed on the weighing pan of the precision balance using a robotic arm. The reading on the precision balance display is observed to ensure that the precision balance display shows 100.0000 grams.

[0101] S3. Determine whether the quality of the modified polypropylene film is within a preset quality range. If the quality of the modified polypropylene film is not within the preset quality range, return to the step of obtaining the modified polypropylene film according to the preparation instruction. If the quality of the modified polypropylene film is within the preset quality range, metallize the modified polypropylene film using a distillation device to obtain a metallized modified film.
[0102] In detail, the modified polypropylene film is metallized by using a distillation device to obtain a metallized modified film, comprising:
[0103] The modified polypropylene film is conveyed to a conveyor belt by using a feeding system to obtain a film to be conveyed;
[0104] The film to be transported is conveyed to the vacuum chamber by a conveyor belt to obtain a vacuum chamber film, and the position of the vacuum chamber film is adjusted by a mechanical arm and a preset position to obtain an adjusted film;

[0109] Importantly, the preset position is a specific position pre-defined in the vacuum chamber. Position adjustment refers to placing the film in a precise position in the vacuum chamber by the robot during the metallization process. The gas mixture ratio refers to the ratio of oxygen and hydrogen introduced into the vacuum environment.

The conveying system refers to a system for conveying a mixed gas of a preset proportion to a vacuum chamber in an absolute vacuum environment. The feeding system described in the embodiment of the present invention is a system for conveying a modified polypropylene film from a storage location to a conveyor belt.
[0111] It should be explained that an absolute vacuum environment refers to an environment in which the air in the container is completely evacuated through a vacuum pump to reach a state close to an absolute vacuum. A mixed vacuum environment refers to an environment in which a mixed gas of a preset proportion is delivered into a vacuum chamber through a conveying system on the basis of absolute vacuum, thereby forming a vacuum environment containing a specific gas composition. A crucible refers to a container used to hold tantalum metal and heat the tantalum metal to a gaseous state under the action of a laser heater. The tantalum metal to be heated refers to the tantalum metal material that has not yet been heated. A laser heater refers to a heating device that uses a laser beam as a heat source to heat the tantalum metal in a crucible, causing it to melt and further evaporate into tantalum vapor.
[0112] Furthermore, obtaining metallic tantalum includes:
[0113] According to a preset mixing ratio, the pre-constructed tantalate, magnesium chips and sodium chloride are mixed to obtain a mixture;
[0114] Using an automatic charging machine to charge the mixture into a crucible to obtain a mixture to be heated;
[0115] Heating the crucible based on the mixture to be heated and the multi-stage temperature control furnace to obtain a heated mixture, wherein the multi-stage temperature control furnace includes: temperature setting, time setting, heating mode and temperature monitoring;
[0116] Turn off the multi-stage temperature control furnace based on the time setting, and use the temperature sensor to detect the multi-stage temperature control furnace after being turned off in real time to obtain temperature data, wherein the temperature sensor presets the time threshold;
[0117] If it is confirmed that the temperature data is greater than a preset temperature threshold, the temperature of the multi-stage temperature control furnace is reduced by using a pre-built fan until the temperature data is less than or equal to the preset temperature threshold, and the heated mixture is taken out by using a pre-built automatic material taking arm to obtain a heated mixture;

The multi-stage temperature control furnace is a heating device used to heat the crucible containing the mixture. The temperature sensor refers to a sensor used to monitor the temperature in the multi-stage temperature control furnace in real time and transmit the temperature data to the control system. The time threshold is a value used to determine the length of time for the multi-stage temperature control furnace to heat.
[0121] It should also be explained that a fan is a device used to quickly reduce the temperature in the multi-stage temperature control furnace until the temperature reaches below a preset temperature threshold after the multi-stage temperature control furnace is turned off. An automatic pickling machine is a device that removes surface impurities of a heated mixture by chemical methods. An automatic feeder is a device that automatically removes a heated mixture from a multi-stage temperature control furnace. A dryer is a device used to remove moisture from the surface of a washed mixture.
[0122] Exemplarily, according to a preset mixing ratio of 1:1:2, 100 grams of tantalate, 100 grams of magnesium chips and 200 grams of sodium chloride are weighed and placed in a pre-constructed mixer for mixing to obtain a mixture. The automatic loader evenly loads the mixture into a crucible to obtain a mixture to be heated. The maximum temperature of the multi-stage temperature control furnace is set to 1200°C, and the heating time is 3 hours. The pre-constructed gradient heating mode is used to first increase the temperature to 600°C at a rate of 5°C per minute, and then continue to increase the temperature to 1200°C after keeping warm for 30 minutes. The temperature in the multi-stage temperature control furnace is monitored in real time by temperature monitoring. When the heating time reaches 3 hours, the multi-stage temperature control furnace is automatically turned off, and the temperature in the furnace after being turned off is detected in real time by a temperature sensor. If the multi-stage temperature control furnace is turned off within 10 minutes after the multi-stage temperature control furnace is turned off, The temperature in the furnace is 700°C, which is higher than the preset temperature threshold of 600°C.
