Description

Technical Field

[0001] The invention relates to a coating device, belongs to the field of wearable sensors, and in particular to an automatic slurry-feeding coating device for making fabric sensors. Background Art

[0002] Wearable sensors are flexible sensors that can be attached to human skin or clothing to collect various health, sports and environmental data. Therefore, fabric sensors are born. Fabric sensors are ultra-thin textile materials that can convert pressure into measurable electrical signals. Such sensors embed flexible or micro sensors into fabrics to sense temperature, pressure, displacement, current and other physical or chemical stimuli. Existing fabric sensors mainly include base fabrics and surface sensing layers. The surface sensing layers are mostly stress sensors, and their main components are various conductive plasmas. Generally, the plasma is coated by screen printing to form a surface sensing layer.

[0003] A Chinese patent with application number 202210667037.4 and application date June 13, 2022 discloses a wearable fabric strain sensor and its preparation method and application. The wearable fabric strain sensor is a layered structure, which includes a modified fabric and a carbon-based ink conductive film covering the surface of one side of the modified fabric; the modified fabric includes a fabric base and a transfer paper that is hot-melt-cured on the side of the fabric base facing the carbon-based ink conductive film, and a conductive electrode is connected to the carbon-based ink conductive film. The preparation method includes the following steps: (a) hot-melt-curing the transfer paper to the surface of the fabric base to form a modified layer to obtain a modified fabric; (b) printing the carbon-based ink on the modified fabric by screen printing, and performing several printings; (c) rolling the obtained fabric-based conductive film and then connecting the conductive electrode. Although this design realizes the production of a surface sensing layer by screen printing, it still has the following defects: In this design, during screen printing, the slurry accumulates more in some areas of the screen and less in other areas due to the action of gravity. When the scraper moves horizontally to push the slurry, some areas of the base material will have more slurry and some areas will have less slurry, so the printing effect is uneven.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In an automatic slurry feeding coating device for making a fabric sensor of the present invention, the device comprises a sizing box and a screen, the sizing box comprises a sizing chamber and a control box, a control area and a communication area are arranged in the control box, a movable plate is arranged in the control area, a cover plate is connected to the top of the movable plate, the communication area is connected to the sizing chamber through a communication hole, one end of the sizing chamber is a sizing port, the end of the sizing box is connected to the bottom of the screen, the screen forms an acute angle with the horizontal plane, the screen is connected to the scraper, when applied, firstly, a sufficient amount of plasma is stored in the sizing chamber, and then the movable plate is moved toward the communication area, the space in the communication area becomes smaller, so the pressure in the communication area is reduced. The force becomes larger, and then the connecting area transmits pressure to the upper pulp chamber through the connecting hole, so the plasma level in one end of the upper pulp chamber near the upper pulp port rises, and then the plasma overflows from the upper pulp port, and then the overflowing plasma is pushed upward along the screen by the scraper, and then the plasma falls on the base material on the rear side of the screen; when the movable plate moves away from the connecting area again, the space in the connecting area becomes larger, so the pressure in the connecting area becomes smaller, and then the connecting area transmits pressure to the upper pulp chamber through the connecting hole, so the plasma level in one end of the upper pulp chamber near the connecting area rises, and the excess plasma level at the upper pulp port drops back to the upper pulp chamber; the advantages of the present invention also include: First point: the screen forms an acute angle with the horizontal plane, that is, the bottom of the screen is lower than the top of the screen. When the scraper moves along the screen, it gradually moves upward. At this time, the plasma is tightly accumulated at the bottom of the scraper under the action of gravity. Therefore, the plasma at the bottom of the scraper is sufficient, and the plasma falling on the base material is sufficient, which can form a uniform printing effect. Second point: because the printing effect of the present invention is uniform, the formed surface sensing layer is tight and uniform, and the acquisition quality of the electrical signal of the surface sensing layer is stable, that is, the sensing effect of the surface sensing layer is stable; Third point: by moving the movable plate toward the connecting area, the pressure in the connecting cavity can be increased so that the sizing port can automatically overflow with plasma, thus realizing the automatic sizing function; Fourth point: by moving the movable plate away from the connecting area, the pressure in the connecting cavity can be reduced to recover the excess plasma at the sizing port, that is, to achieve the effect of recovering the excess slurry; at this time, the cover plate seals the sizing port and also protects the plasma to prevent the plasma from failing; Therefore, the printing effect of the present invention is uniform and has an automatic sizing function.

[0017] 2. In the automatic slurry feeding coating device for making fabric sensors of the present invention, a placement end is provided at one end of the slurry box, and the placement end includes a placement plate and an inclined plate, and a screen is sandwiched between the placement plate and the inclined plate. When used, the bottom of the screen is placed between the placement plate and the inclined plate, so that the bottom of the screen can be fixed, the position of the screen is stable, and thus the printing process is stable. Therefore, the printing process of the present invention is stable.

[0018] 3. In the automatic slurry feeding coating device for making fabric sensors of the present invention, a cover plate column is arranged on the top of the cover plate, and a moving spring is arranged on one side of the moving plate. When in use, the scraper moves to the right, driving the cover plate column to move to the right, and then the cover plate moves to the right, so the cover plate is away from the sizing port, and the plasma can overflow from the sizing port. At this time, the moving spring is stretched; when the scraper is away from the cover plate column, the moving spring releases the elastic force to move the moving plate to the left, so that the cover plate can move to the left to connect with the sizing port, thereby sealing the sizing port and avoiding the failure of the plasma. Therefore, the present invention has a better protective effect on plasma.

[0019] 4. In the automatic slurry feeding coating device for making fabric sensors of the present invention, the slurry box includes a front guide track and a rear guide track, and the two sides of the cover plate are respectively inserted into the front guide track and the rear guide track.

Therefore, the matching of the components in the present invention is good. BRIEF DESCRIPTION OF THE DRAWINGS
