Description

Technical Field

[0001] The present invention relates to the field of pipeline packaging of paper-based flexible capacitive sensors, and specifically to a pipeline packaging device for paper-based flexible capacitive sensors. Background Art

[0002] With the continuous development of fields such as wearable electronics, biomedicine, and behavior monitoring, the demand for flexible electronic products is increasing. Among them, paper-based flexible capacitive sensors, as an environmentally friendly new type of electronic product, have attracted extensive attention due to their low cost and simple process. Paper-based flexible capacitive sensors are beginning to be more and more widely used in various occasions. The structure of a paper-based flexible capacitive sensor is to place a capacitive layer with a relatively large dielectric constant between a pair of paper-based electrodes. However, although the paper-based flexible capacitive sensor is relatively simple to manufacture, there are still certain difficulties in its overall packaging. Due to the presence of fine depressions and protrusions on the surface of the paper-based material, a smooth thin film cannot be used for the packaging process. At the same time, the extended wires limit the shape of the packaging layer. Therefore, it is particularly important to find a packaging process that can adapt to paper-based flexible capacitive sensors.

[0003] The traditional packaging process flow of flexible capacitive sensors is mainly to send the entire flexible capacitive sensor through a conveyor belt into the upper and lower packaging films, then use a heating machine to perform high-temperature packaging on the sides, and finally cut it to a predetermined shape by a cutting machine. Although the traditional packaging process flow can complete the packaging of flexible sensors in large quantities, it is large in size, and the flexible capacitive sensors with unencapsulated sides are prone to falling out during the packaging process. Therefore, it is necessary to design a pipeline packaging device that is small in size, high in efficiency, can prevent the capacitive sensor from falling out, and can adapt to paper-based flexible capacitive sensors.

[0004] Based on the above problems, the present invention provides a paper-based flexible capacitive sensor pipeline packaging device, which includes a central material transport turntable, a droplet robot for adding bottom and top packaging liquids, a pair of independently operating sandwich dryers, a pair of different transfer manipulators, a pair of conveyor belts for feeding and discharging, and a side packaging machine. The present invention fixes the central material transport turntable in the middle of the device to realize the material transport function in the packaging process. At the same time, the bottom packaging liquid droplet robot and the top packaging droplet robot are respectively used to add the bottom and top packaging liquids. In addition, a pair of independently operating sandwich dryers are provided to dry the bottom and top packaging liquids respectively. In addition, the clamp transfer manipulator transfers the paper-based flexible capacitive sensor to be packaged conveyed by the feeding conveyor belt, and at the same time, the transfer adsorption manipulator is used to adsorb and transfer the paper-based flexible capacitive sensor that has completed the bottom and top packaging, and place it on the discharging conveyor belt. Finally, the side packaging machine packages the side of the paper-based flexible capacitive sensor. The cooperation of the above parts makes the present invention have the advantages of small volume, high efficiency, preventing the paper-based flexible capacitive sensor from coming out, and being able to adapt to the surface of the paper-based material for packaging, solving the problems of large floor area in the current flexible capacitive sensor packaging process, inability to adapt to the surface of the paper-based material, and the flexible capacitive sensor with unencapsulated sides being prone to coming out during the packaging process. Summary of the Invention
