DETAILED DESCRIPTION

[0032] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications. Example

[0033] refer to Figure 1-Figure 3In this embodiment, a negative pressure applicator is proposed for adsorbing and applying stickers such as energy consumption stickers, nameplates, and labels. The negative pressure applicator comprises an applicator plate, a negative pressure housing 2, and a cover plate 3. The applicator plate may be an applicator foam 1, or other elastic materials. The applicator foam 1 is a flat plate, typically rectangular, to facilitate the adsorption and application of stickers. The specific dimensions need to be set according to the specific situation. The applicator foam 1 is made of a soft material, and a plurality of transparent air channels are provided on the applicator surface. These air channels are generally evenly arranged, but other arrangements are not excluded. Because the applicator foam 1 is soft, the sticker can fully contact the applied product. Taking a refrigerator as an example, the application can avoid incomplete adhesion. An isolation layer is provided at the edge and air channel of the applicator foam 1. The specific method can be achieved by hot-melt cutting, which will not be described in detail here. This prevents side leakage of the applicator foam 1. At the same time, the inconvenience of manually handling stickers is avoided, making automatic application possible. The thickness of the application foam 1 at one end can be greater than that at the other end, and the application surface is a plane. In the actual working process, the end of the application foam 1 with a larger thickness is at the top, and when the application surface of the application foam 1 adsorbs the sticker, the sticker is then applied to an electrical appliance such as a refrigerator. Since the upper end of the application foam 1 is thick, the upper end of the sticker first contacts the refrigerator, and then starts to contact downward in sequence, which facilitates the removal of bubbles. The opposite surface of the application surface of the application foam 1 is fixedly connected to the negative pressure shell 2. The shape of the negative pressure shell 2 corresponds to that of the application foam 1, and supports the application foam 1. The negative pressure shell 2 is a plate-like structure with a rectangular depression. The application foam 1 and the negative pressure shell 2 can be adhered and fixed. An airway is provided on the negative pressure shell 2, and the airway on the negative pressure shell 2 is connected to the airway on the application foam 1. A cover plate 3 is fixedly connected to the negative pressure shell 2. The negative pressure shell 2 and the cover plate 3 form a cavity. A connection port is provided on the cover plate 3. The cavity is connected to the connection port. The negative pressure shell 2 and the cover plate 3 can be fixedly connected by screws, so as to facilitate disassembly and assembly. The screws can be provided at the edges of the negative pressure shell 2 and the cover plate 3 to form a complete cavity. The number of the connection ports is designed according to actual needs, and the details are not described here. A sealing gasket can be provided between the negative pressure shell 2 and the cover plate 3 to prevent air leakage in the cavity. An optical fiber sensor 4 is provided on the negative pressure patch. A mounting through hole is provided on the specific cavity, and a clearance hole is provided on the patch foam 1. The optical fiber sensor 4 can be installed in the mounting through hole, so as to facilitate sensing of the sticker on the application surface of the patch foam 1. Of course, other installation methods are not excluded. The mounting hole needs to be separated from the cavity. Specifically, a sealing ring is required inside the negative pressure housing 2. The sealing ring is located outside the mounting hole and separates the mounting hole from the cavity. The optical fiber sensor 4 is installed in the mounting hole on the cover plate 3 and extends through the cavity to the application surface of the application foam 1. This facilitates the installation of the circuit and prevents the circuit from affecting the adsorption. The overall structure is mainly used for the adsorption and application of the sticker.When taking the material, there is a certain negative pressure inside the cavity, and there is a certain adsorption force on the applying surface of the applying foam 1, so the sticker can be adsorbed flatly on the applying surface of the applying foam 1. After the optical fiber sensor 4 is blocked, it will send a signal of successful adsorption; after the material is taken successfully, the sticker is spread on the surface of the refrigerator door by the applying foam 1, thereby completing the application. Example

[0034] refer to Figure 4-Figure 6In this embodiment, an application assembly is proposed, including a negative pressure applicator and a mounting plate 8. The mounting plate 8 and the negative pressure applicator are connected by a connecting unit. Four connecting units can be provided to make the connection smooth. Of course, other quantity settings are not excluded. The connecting unit can also connect the application surface of the negative pressure applicator at an angle, which will not be elaborated here. The connecting unit may include a movable joint and an elastic connecting member. The elastic connecting member includes a linear bearing seat 9, a return spring 7, and an optical axis. The linear bearing seat 9 is fixedly connected to the mounting plate 8. The optical axis is slidably nested in the interior of the linear bearing seat 9. One end of the optical axis extends out of the linear bearing seat 9 and is connected to the movable joint. A return spring 7 is nested on the optical axis. The return spring 7 has a buffering effect on the negative pressure applicator, thereby realizing buffering application of the sticker. Of course, the elastic connecting member may also have other structures, which will not be elaborated here. The movable joint may include an application joint 5 and a joint connector 6. The joint connector 6 is fixedly connected to one end of the optical axis. The joint connector 6 may be provided with nesting holes and fixed by screws. The application joint 5 is fixedly connected to the cover plate 3 and the rotationally connected joint connector 6. The elastic buffering of each connection unit enables the negative pressure application component to rotate at a small angle. The movable joint formed by the application joint 5 and the joint connector 6 may include a vertically arranged transverse rotating member and a longitudinal rotating member. The transverse rotating member and the longitudinal rotating member have rotating planes perpendicularly connected. The transverse rotating member can rotate the application component horizontally, and the longitudinal rotating member can rotate the application component vertically, so that it can be applied to the transverse and longitudinal curved surfaces of the door of a refrigerator or other electrical appliance box. Of course, the application joint 5 can also be a universal ball structure. The transverse rotating member and the longitudinal rotating member may include a rotating seat 12 and a central axis 13. The rotating seat 12 and the central axis 13 can be rotatably nested and connected. The specific details are prior art and will not be described here. The application component is also connected to a position sensing unit, which is used to sense the degree of pressure of the negative pressure application component. The position sensing unit may include a sensing sheet 10 and a sensor 11. The sensing sheet 10 may be fixedly connected to the other end of the optical axis, and the sensor 11 may be fixedly connected to the mounting plate 8. When applying the sticker to the refrigerator, the negative pressure applicator will be pressed against the door of the refrigerator. The application joint 5 is forced to drive the sensing sheet 10 on the optical axis to retreat, and at the same time, the reset spring 7 is compressed. When the sensing sheet 10 passes through the sensor 11, it proves that the application force is moderate and has reached the specified position, that is, the application action can be performed (the application action is applied from top to bottom, not directly on the surface of the refrigerator. This can avoid bubbles directly generated between the energy-consuming sticker and the refrigerator). After the application is completed, the reset spring 7 is reset, the sensing sheet 10 is separated from the sensor 11, and the negative pressure applicator is reset.When the refrigerator door is a curved surface, when the negative pressure applicator is pressed on the surface of the refrigerator, due to the uneven force, the entire structure will passively rotate in space due to the existence of the applicator joint 5 (when the force is uneven, the force will always be squeezed in the smaller direction). The adaptive rotation of the curved surface of the refrigerator door can solve the energy consumption applicator problem of the curved surface. Example

[0035] refer to Figure 7 In this embodiment, a visual patch module is proposed. The visual patch module includes a visual component 15, which is fixedly connected to the aforementioned patch component. The collection surface of the visual component 15 and the application surface of the application component face the same direction. The details are not described in detail here. The visual component 15 can be fixedly connected to the mounting plate 8 or connected via a frame. The visual component 15 can include a camera and a lighting component. The camera and lighting component are fixed to the mounting plate 8 or the frame. The camera and lighting component face the same direction. The lighting component can illuminate the working surface of the refrigerator, and the camera captures an image of the working surface of the refrigerator. The specific details can be existing technology and are not described in detail here. The mounting plate 8 or the frame can also be fixedly connected to a connecting flange 14, which is used to be fixedly connected to a robotic arm. During the specific operation process, the visual component 15 takes a photo of the refrigerator door to obtain a photo of the refrigerator door, then analyzes the photo of the refrigerator door to determine the application point. The robotic arm then moves the application component to the application point for application. The specific process is not described in detail here.
