Description

Technical Field

[0001] The utility model belongs to the field of electrode sheet preparation, in particular to a device for coating a protective layer on an electroencephalogram cap electrode sheet. Background Art

[0002] Electrodes are an essential component of an EEG cap, serving as a medium for signal collection and transmission. They are typically pressed from silver powder, then soldered with silver wire. Finally, a protective layer, such as epoxy resin, is applied to the surface to secure the wires and protect the electrode surface.

[0003] The current method of applying epoxy resin is to fix the electrode sheet to a cylinder with an inner diameter that meets the requirements, and then manually apply liquid epoxy resin to the surface of the electrode sheet little by little to give it a natural curve. However, this method is time-consuming and labor-intensive, and its efficiency is very low. During the application process, it is easy for epoxy resin to be applied to the outside of the electrode sheet, which requires subsequent reprocessing, resulting in a low yield rate and high costs. Utility Model Content

[0006] The depth h of the groove is 1-5 mm, wherein the difference between the depth of the groove and the thickness d of the electrode sheet is 1-2 mm. A plurality of line gaps are provided on the main structure at locations corresponding to the grooves, and the line gaps are connected to the grooves.

[0007] Preferably, the groove is circular or rectangular.

[0008] Preferably, the line gap is used to lead out the wires on the electrode sheet, and the width of the line gap is less than 0.1 mm.

[0012] Beneficial effects

[0013] When the utility model is in use, the electrode sheet is first inserted into the groove, the wire is led out through the line gap, and then the protective layer raw material is added into the groove and left to stand. After the protective layer raw material is solidified on the top of the electrode sheet, the electrode sheet with the protective layer is peeled out of the groove by extrusion. Compared with the method of artificially coating the protective layer raw material in the prior art, the feeding method is simpler, more efficient, and has a higher yield rate.

[0021] Example 1

[0022] See also Figure 1 As shown, the present invention provides a device for coating a protective layer on an EEG cap electrode sheet, comprising a main structure 1, the main structure 1 being made of an elastic material, such as silicone, and provided with a plurality of grooves 2. The sizes of the different grooves 2 are the same or different, and the sizes of the grooves 2 are set according to the structure of the electrode sheet 4 to be coated, such as a circular, rectangular, or other shape. The size of the groove 2 is adapted to the electrode sheet 4, and the electrode sheet 4 can be fixed in the groove 2. The size of the groove 2 can be slightly smaller than the electrode sheet 4. For example, when the electrode sheet 4 is circular, the size of the groove 2 is 0.3 to 0.6 mm smaller than the size of the electrode sheet 4, and is used to clip the electrode sheet 4 into the groove 2.

[0023] The depth h of the groove 2 is 1 to 3 mm, wherein the difference between the depth of the groove 2 and the thickness d of the electrode sheet 4 is 1 to 2 mm, for example, 1 mm. After the electrode sheet 4 is placed in the groove 2, there is a 1 to 2 mm empty space on the top of the electrode sheet 4, which is used to pour the protective layer raw material and solidify it.

[0024] Several line gaps 3 are also provided on the main structure 1 at locations corresponding to the grooves 2. The line gaps 3 are connected to the grooves 2. The depth of the line gaps 3 depends on the thickness of the electrode sheet 4. The line gaps 3 are used to lead out the wires on the electrode sheet 4. In order to prevent the protective layer material from entering the line gaps 3, the width of the line gaps 3 is less than 0.1 mm so that the wires can be inserted. After the wires are inserted, the main structure 1 can close the line gaps 3 under the action of elastic deformation.

[0025] The length of the line gap 3 is less than 5 mm. If it is too long or too short, the wire may break easily.

[0026] When the present invention is in use, the electrode sheet 4 is first inserted into the groove 2, the wire is led out through the line gap 3, and then the protective layer raw material is added into the groove 2 and left to stand. After the protective layer raw material is solidified on the top of the electrode sheet 4, the electrode sheet 4 with the protective layer is peeled off from the groove 2 by extrusion. Compared with the method of artificially coating the protective layer raw material in the prior art, the feeding method is simpler, more efficient, and has a higher yield rate.

[0027] The above examples illustrate the specific implementation methods of the present invention. However, the scope of protection of the present invention is not limited to the above-mentioned exemplary implementation methods. Any modifications, equivalent substitutions, improvements, etc. made by those skilled in the art within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
