Abstract
Description
Technical Field
[0001] The utility model relates to the field of electronic skin, in particular to a flexible electronic skin structure which is convenient for rolling and pasting. Background Art
[0002] As the largest organ in the human body, the skin performs a variety of biological functions. For example, the dense epidermal cells protect against damage from external physical, chemical, and biological factors; the pores on the skin effectively release excess heat, playing a cooling role; and the nerve receptors throughout the skin give humans a keen sense of touch and hot and cold sensations. With the continuous emergence of new materials and the development of electronic technology, artificial electronic skin has gradually become a research hotspot. In recent years, artificial skin based on nanomaterials and nanostructures has demonstrated excellent performance such as high sensitivity and high stability. In addition, the combination with a variety of sensor devices makes artificial electronic skin not only have functions similar to human skin, but also have other special functions, such as the detection of sound, light, and electromagnetic wave signals.
[0003] Electronic skin can be attached to the surface of robots to help them detect external stimuli and respond appropriately. It is directly related to the intelligence and multifunctionality of carriers such as robots, medical equipment, human prostheses, and wearable devices. It can be widely used in many fields such as production, life, rehabilitation and medicine.
[0004] Existing electronic skins are generally bonded directly to robotic arms when in use. Since the electronic skin is directly exposed to the outside, once a collision occurs, it is very easy to cause damage to the surface of the electronic skin, affecting the service life of the electronic skin. In addition, due to the good flexibility of the electronic skin, it is relatively difficult to roll up the electronic skin. Utility Model Content
[0005] (1) Technical problems to be solved
[0006] In order to overcome the problem that the existing electronic skin is generally directly bonded to the robot arm when in use, since the electronic skin is directly exposed to the outside, once a collision occurs, it is very easy to cause damage to the surface of the electronic skin, affecting the service life of the electronic skin. In addition, due to the good flexibility of the electronic skin, it is more difficult to roll up the electronic skin.
[0007] (2) Technical solution
[0008] The technical solution of the present utility model is: a flexible electronic skin structure that is easy to roll up and stick, including a base, and also including an elastic sealing ring, a lower electrode sheet, an upper electrode sheet, a sensing layer, an insulating layer, a rubber protective pad, a first contact and a second contact. The lower electrode sheet is fixedly bonded to the upper surface of the base, and a plurality of second contacts are fixedly connected to the surface of the lower electrode sheet at equal intervals. An upper electrode sheet is arranged above the lower electrode sheet, and the bottom surface of the upper electrode sheet is fixedly connected to the first contact at equal intervals. The first contact and the second contact correspond one to one. An elastic sealing ring is fixedly connected between the upper electrode sheet and the lower electrode sheet, and a sensing layer is provided on the side of the upper electrode sheet away from the lower electrode sheet, an insulating layer is provided on the surface of the sensing layer, and a rubber protective pad is provided on the side of the insulating layer away from the sensing layer.
[0009] Preferably, by providing a rubber protective pad, the impact force on the surface of the electronic skin can be buffered during use, preventing foreign objects from directly impacting the electronic skin, thereby providing a certain degree of protection for the electronic skin during use and improving the service life of the electronic skin. By providing a flexible winding strip, when winding up for storage, the flexible winding strip is wound up, and the electronic skin is then wound up using the flexible winding strips on both sides, thereby avoiding the situation where the electronic skin is soft and causes uneven winding, saving time and effort.
[0010] Furthermore, a variety of sensors are arranged inside the sensing layer, and the sensors are all electrically connected to the lower electrode sheet and the upper electrode sheet.
[0011] Furthermore, the insulating layer is made of soft rubber material, which can resist the flow of current to a certain extent, ensuring that the electronic skin will not leak electricity during use.
[0012] Furthermore, a waterproof layer is fixedly provided on the bottom surface of the base. The waterproof layer is made of silicon nitride material or silicon oxide material, which can prevent water vapor in the external environment from entering the electronic skin, thereby ensuring the normal use of the electronic skin.
[0013] Furthermore, the side of the waterproof layer away from the base is fixedly connected with adhesive, and the side of the adhesive away from the waterproof layer is adhered with release paper. When in use, the electronic skin structure can be pasted on the surface of the robot arm by peeling off the release paper and using the adhesive, which is convenient and quick to install.
[0014] Furthermore, a plurality of elastic balls are fixedly connected between the upper electrode sheet and the lower electrode sheet at equal intervals. When no external force is applied, the elastic force of the elastic balls can separate the first contact and the second contact from each other to facilitate sensing of subsequent pressure.
[0015] Furthermore, flexible rolling strips are symmetrically arranged on the surface of the rubber protective pad, and the bottom surface of the flexible rolling strips is fixedly connected with a pressure-sensitive adhesive. The flexible rolling strips are fixedly connected to the rubber protective pad through the pressure-sensitive adhesive. The hardness of the flexible rolling strips is greater than the hardness of the electronic skin. When rolling up for storage, the flexible rolling strips are rolled up, and the flexible rolling strips on both sides are used to roll up the electronic skin, thereby avoiding the situation where the electronic skin is soft and the rolling is not smooth.

DETAILED DESCRIPTION
[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0032] Example 1:
[0033] See also Figure 1-6The utility model provides an embodiment: it includes a substrate 1, an elastic sealing ring 2, a lower electrode sheet 3, an upper electrode sheet 4, a sensing layer 9, an insulating layer 10, a rubber protective pad 12, a first contact 13 and a second contact 14, the lower electrode sheet 3 is fixedly bonded to the upper surface of the substrate 1, a plurality of second contacts 14 are fixedly connected to the surface of the lower electrode sheet 3 at equal intervals, an upper electrode sheet 4 is provided above the lower electrode sheet 3, a first contact 13 is fixedly connected to the bottom surface of the upper electrode sheet 4 at equal intervals, and the first contact 13 and the second contact 14 correspond to each other one by one, an elastic sealing ring 2 is fixedly connected between the upper electrode sheet 4 and the lower electrode sheet 3, a sensing layer 9 is provided on the side of the upper electrode sheet 4 away from the lower electrode sheet 3, an insulating layer 10 is provided on the surface of the sensing layer 9, and a rubber protective pad 12 is provided on the side of the insulating layer 10 away from the sensing layer 9. When in use, the rubber protective pad 12 can buffer the impact force on the surface of the electronic skin to prevent foreign objects from directly hitting the electronic skin, thereby playing a certain protective role for the electronic skin during use. To improve the service life of the electronic skin, a variety of sensors are arranged inside the sensing layer 9, and the sensors are electrically connected to the lower electrode sheet 3 and the upper electrode sheet 4. The insulating layer 10 is made of soft rubber material, which can resist the flow of current to a certain extent, ensuring that the electronic skin will not leak during use. A waterproof layer 6 is fixedly arranged on the bottom surface of the base 1. The waterproof layer 6 is made of silicon nitride material or silicon oxide material, which can prevent water vapor from the external environment from entering the electronic skin, ensuring the normal use of the electronic skin. The side of the waterproof layer 6 away from the base 1 is fixedly connected with adhesive 5, and the side of the adhesive 5 away from the waterproof layer 6 is adhered with release paper 7. When in use, the electronic skin structure can be posted on the surface of the robot arm by peeling off the release paper 7 and using the adhesive 5. The installation is convenient and quick. A plurality of elastic balls 8 are fixedly connected at equal distances between the upper electrode sheet 4 and the lower electrode sheet 3. When not subjected to external force, the first contact 13 and the second contact 14 can be separated from each other by the elastic force of the elastic ball 8 to facilitate sensing of subsequent pressure.
[0034] It should be noted that the sensing module in the sensing layer 9 is a well-known and mature technology.
[0035] When using this electronic skin, first cut a certain length of electronic skin according to the actual usage, then tear off the release paper 7 on the bottom of the electronic skin, and stick the entire electronic skin on the surface of the robot arm through the adhesive 5, and then electrically connect the electronic skin to the robot hub, and it can be used. During use, when the robot arm is subjected to pressure, the pressure first acts on the rubber protective pad 12, and then acts on the upper electrode sheet 4 through the rubber protective pad 12. At this time, the upper electrode sheet 4 is pressed and moves downward. The upper electrode sheet 4 moves downward and then enables the first contact 13 and the second contact 14 to contact each other. At this time, the circuit between the upper electrode sheet 4 and the lower electrode sheet 3 is connected, and then the induction area 9 is connected. The sensing module is powered on, and the sensing module is used to sense the outside world, and the sensed information is sent to the robot's central system, thereby controlling the robot arm to move. When the electronic skin is not under pressure, the first contact 13 and the second contact 14 are separated from each other by the elastic force of the elastic ball 8. At this time, the circuit between the upper electrode sheet 4 and the lower electrode sheet 3 is disconnected, and the sensing module in the sensing area 9 is not powered, so as to facilitate sensing of subsequent pressure. By setting the insulating layer 10, the flow of current can be resisted to a certain extent, ensuring that the electronic skin will not leak during use. By setting the waterproof layer 6, water vapor in the external environment can be prevented from entering the electronic skin, ensuring the normal use of the electronic skin.
[0036] Example 2:
[0037] See also Figure 1-6 In this embodiment, flexible rolling strips 11 are symmetrically provided on the surface of the rubber protective pad 12, and a pressure-sensitive adhesive 15 is fixedly connected to the bottom surface of the flexible rolling strip 11. The flexible rolling strip 11 is fixedly connected to the rubber protective pad 12 through the pressure-sensitive adhesive 15. The hardness of the flexible rolling strip 11 is greater than the hardness of the electronic skin. When rolling up for storage, the flexible rolling strip 11 is rolled up, and the flexible rolling strips 11 on both sides are used to roll up the electronic skin, thereby avoiding the situation where the electronic skin is soft and the rolling is not smooth.
[0038] When the electronic skin is not in use, one side of the electronic skin is wrapped around the surface of the rotating shaft and fixed, and then the electronic skin is held by the flexible winding strips 11 on both sides. Since the hardness of the flexible winding strips 11 is greater than that of the electronic skin, when winding, the flexible winding strips 11 are controlled to be wound, so as to drive the electronic skin to be wound, thereby avoiding the situation where the electronic skin is not wound smoothly due to its softness. In subsequent use, the electronic skin is fixed on the surface of the robot arm, and then the flexible winding strips 11 and the pressure-sensitive adhesive 15 at the bottom are removed from the surface of the rubber protective pad 12, so that there is no debris on the surface of the electronic skin, and the sensing work of the electronic skin is utilized.
[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the purpose of the present invention.
