Description

Technical Field

[0001] The present invention relates to the technical field of flexible sensors, and more specifically, to a manufacturing device and a manufacturing method for a flexible sensor. Background Art

[0002] With the rapid development of science and technology, flexible sensors, as an important part of the new generation of sensor technology, are increasingly widely used in many key fields, including medical, aerospace, consumer electronics, environmental monitoring, etc. Flexible sensors can flexibly adapt to various complex application scenarios due to their good flexibility, ductility, bendability and even foldability, and are widely used in pressure sensors, strain sensors, touch sensors, biosensors and other fields. At the same time, flexible sensor silver paste plays an important role in the rapidly developing field of electronics and intelligent technology, opening up broad application prospects for creating more types of flexible and wearable sensors.

[0003] However, in the manufacturing process of flexible sensors, a core technical link is to evenly coat silver paste on a flexible substrate to form a conductive layer to achieve current conduction and signal detection functions. It has excellent conductivity and flexibility, and can form a uniform conductive layer on a flexible substrate to achieve high-sensitivity sensing functions.

[0004] The existing manufacturing process relies too much on manual technical intervention and has many shortcomings. The traditional manual coating method is not only time-consuming and labor-intensive, but also difficult to ensure the uniformity and consistency of the coating. With the rapid growth in demand for flexible sensors, this inefficient manufacturing method can no longer meet the needs of large-scale production. In addition, the existing coating devices can only adopt fixed modes and parameters, which are difficult to adapt to the diverse needs of different flexible sensor designs. This limits the application and development of flexible sensors in more fields. In view of the above limitations, it is particularly important to develop an efficient, automated, and intelligent flexible sensor manufacturing equipment; in view of this, we propose a manufacturing equipment and a method for a flexible sensor.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention arranges a belt conveyor and a dust-free spray chamber on a manufacturing machine, utilizes the belt conveyor to transfer the flexible substrate of the flexible sensor to the position of the dust-free spray chamber, sprays silver paste onto the photosensitive film of the nylon screen frame through the silver paste spraying mechanism inside the dust-free spray chamber, and then evenly scrapes the silver paste through the silver paste scraping mechanism. The silver paste scraping mechanism in the present invention drives the stroke adjustment component through the driving component so that the movable interlaced component drives the diffusion scraper to perform the adjustment function, so that the scraping path and range can be adjusted according to specific needs to meet the manufacturing needs of flexible sensors of different specifications and shapes. Secondly, the silver paste spraying mechanism adjusts the spraying silver paste dosage and spraying force, and accurately controls the spraying force, dosage and scraping stroke of the silver paste, which can ensure that the key parameters of each sensor in the manufacturing process remain consistent, thereby improving the applicability and production efficiency of the equipment.

[0018] 2. In the present invention, when the servo motor drives the threaded rod to rotate on the first sleeve, the threaded rod drives the rotating shell to rotate, the rotating shell drives the deflection block to rotate, the deflection block drives the L-shaped rod to shake, and the L-shaped rod drives the movable interlacing component to move, so that the movable interlacing component drives the diffusion scraper to perform reciprocating scraping and smearing movements. Compared with manual scraping and coating, it saves labor and improves the production efficiency of scraping and coating silver paste, which is conducive to large-scale continuous manufacturing of flexible sensors.

[0019] 3. In the present invention, by manually rotating the adjusting rod, the wire groove on the adjusting rod rotates to move the position of the movable sleeve, and the movable sleeve drives the connecting block and the deflection block to shift the position of the deflection block inside the rotating shell, so that the L-shaped rod drives the connecting rod and the rotating ball to change the swing amplitude in the swing groove. When the swing amplitude of the connecting rod changes, the distance that the interlaced rod moves in the second sleeve changes, thereby adjusting the scraping stroke distance of the diffusion scraper. By precisely controlling the scraping stroke, the uniform distribution of the silver paste on the flexible substrate can be ensured, further improving the performance stability and consistency of the sensor.

[0020] 4. In the present invention, a bottom hole is provided at the bottom end of the outer box of the injection box, and a top plate and a bottom plate are provided at the top and bottom ends of the bottom hole respectively. A rotating inner gear ring is rotatably provided between the top plate and the bottom plate, four second gears are rotatably provided, four limit blocks are fixedly provided, and a movable gear block is movably sleeved on the limit block, the rotating inner gear ring is meshingly connected with the second gear, and the second gear is meshingly connected with the movable gear block. Therefore, when the driving rod position moves, it drives the rotating inner gear ring to rotate, and the rotating inner gear ring meshes to drive the four second gears to rotate synchronously, and the second gear meshes to drive the four movable gear blocks to achieve the effect of synchronous movement and opening, so that the radius of the injection nozzle can be controlled, the amount of silver paste used can be accurately controlled, and unnecessary waste and pollution can be avoided. This meets the requirements of modern manufacturing industry for environmental protection and energy saving. Since the price of silver paste raw materials is relatively high, production costs can be further saved, which is beneficial to the production development of enterprises.

[0021] 5. In the present invention, crawlers are mounted on two rotating shafts symmetrically arranged at the top of the plate body. The rotating shafts and crawlers are driven to rotate by a driving motor, and the crawlers drive the steel teeth arranged on the outer wall to move. Since the steel teeth and the driving rod are located on the same horizontal line, when the steel teeth move, the driving rod is pushed to move. The movement of the driving rod realizes the synchronous and precise control of multiple injection boxes, which has lower energy consumption and higher energy utilization rate than existing or traditional equipment.
