Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of conductive pad surface coating in the assembly of complete machines. Specifically, it relates to a conductive adhesive coating tool between structural components and connectors, which is used for applying conductive adhesive between the conductive rubber pad between the housing and the connector and the conductive rubber pad. Background Technology
[0002] During the assembly of electronic product connectors (with conductive rubber pads), to ensure good conductivity between the connector and the housing, conductive adhesive is often applied between the housing and the conductive rubber pad before screws are used to fasten the connector, conductive rubber pad, and housing together. Currently, the conductive adhesive is applied manually. Manually applied adhesive has poor thickness consistency, the application boundary is difficult to fully meet the drawing requirements, the application efficiency is low, and improper application may create conductive excess material that falls into the housing and affects the product's electrical performance. This method also requires a high level of skill from the operator.
[0003] With increasing demands for product quality and production efficiency, finding a reliable and efficient application method is crucial. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a conductive adhesive coating fixture between structural components and connectors. This fixture assists in applying conductive adhesive, ensuring that operators can efficiently and accurately apply the conductive adhesive to the mounting surfaces of the housing and connectors, effectively improving the application efficiency and consistency of the conductive adhesive.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A conductive adhesive coating fixture for bonding structural components and connectors includes a stencil and a frame, wherein...
[0007] The frame is a hollow cuboid structure with openings at the top and bottom, and the inner side of the frame matches the outer side of the structural component.
[0008] The mesh plate is fixed to the upper open end face of the mesh frame and includes an array of openings. The openings are used for positioning the conductive adhesive. The mesh plate does not have openings at the corresponding positions of the hole areas of the structural components.
[0009] Furthermore, the mesh plate is fixed to the upper open end face of the mesh frame by mesh plate mounting fasteners.
[0010] Furthermore, the surface roughness of the upper surface of the mesh frame is no greater than 0.2 μm, which is used to bond with the plane of the mesh plate.
[0011] Furthermore, the openings of the mesh plate are rectangular, and the distance between the arrayed rectangles is 0.2-0.5mm.
[0012] Furthermore, a coating scraper is used to apply conductive adhesive to the surface of the stencil, and the conductive adhesive is applied to the mounting surface of the housing connector through the openings in the stencil.
[0013] Furthermore, the shape of the mesh plate and the position of the mesh plate openings are consistent with the shape and structure of the housing connector mounting surface.
[0014] Furthermore, the fastener for mounting the mesh plate is an M1.5 screw.
[0015] Furthermore, the mesh frame is wrapped around the housing connector mounting base on the housing, conductive adhesive is squeezed onto the surface of the mesh, and excess conductive adhesive is scraped off using a coating scraper.
[0016] Furthermore, the mesh plate is made of stainless steel, the thickness of which matches the thickness of the adhesive coating, and the surface roughness is no greater than 0.2μm.
[0017] Furthermore, after the coating is completed, the coating fixture is removed.
[0018] The beneficial effects of this utility model are as follows:
[0019] Improved coating accuracy: The perforated design of the stencil ensures that the conductive adhesive is precisely applied to the designated positions on the mounting surface of the housing connector, avoiding over-application or omission and meeting the requirements of the drawings.
[0020] Ensure consistency: The thickness of the stencil matches the thickness of the adhesive coating, and the surface roughness is ≤0.2μm, so that the adhesive layer thickness is uniform and the differences caused by manual operation are reduced.
[0021] Highly efficient and convenient: The scraper, in conjunction with the screen, can quickly apply the coating in just 2-3 passes, significantly improving production efficiency and reducing reliance on operator skills.
[0022] Anti-pollution design: The mesh plate covers the connector mounting holes on the housing to prevent conductive adhesive from seeping in and forming excess material, thus ensuring the electrical performance of the product.
[0023] Simple and lightweight structure: The combination of stainless steel mesh and synthetic stone mesh frame results in a small size, light weight, low cost, strong adaptability, and easy installation and maintenance. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0030] like Figures 1-2 As shown, this utility model provides a conductive adhesive coating fixture between a structural component and a connector. Figure 1 A schematic diagram of the layout is given, in which structural component A is coated with conductive adhesive by the coating tool B of this utility model. Its core is to design a square platform composed of two parts: a mesh plate 2 and a mesh frame 1, and to connect the two parts with the help of standard parts.
[0031] The frame 1 is used to fix the mesh plate 2 and can completely cover the mounting surface of the housing connector. It determines the application position of the conductive adhesive on the mounting surface of the housing connector. The frame 1 is a hollow cuboid structure with openings at the top and bottom.
[0032] The mesh plate 2 is designed with as many openings as possible, based on the size of the connector to be coated and the size of the mesh frame 1. The mesh plate 2 is not designed with openings at the contact positions between the mesh plate 2 and the mesh frame 1 and the corresponding positions of the structural component hole areas. Instead, openings are made on the mesh plate 2 according to the mounting surface of the shell connector and the mesh plate 2, to the maximum extent possible (the square frame on the mesh plate 2 and the openings on the mesh plate 2 can be changed according to the actual situation, and the shape is mostly rectangular). Figure 2 Taking the XC158 series connector as an example, the structural component holes for mounting the XC158 series connector are circular. Therefore, the central circular area of this device is the non-perforated position of the mesh plate 2. The perforated shape is rectangular, arranged in an array, with a distance of 0.2mm between rectangles. The size and distance between rectangles can be set arbitrarily, but to ensure the coating area of conductive adhesive, the spacing should not exceed 0.5mm. The center does not necessarily have to be circular; the shape is determined by the structural component holes, and the outer frame is determined by the outer frame of the structural component holes. The perforations can be of any shape; the purpose is to ensure the coating area of conductive adhesive. Other shapes are difficult to control in terms of dosage and coating quality. This ensures that the maximum area of the area to be coated on the housing connector mounting surface is exposed, but no holes should be made at the housing connector mounting hole positions. Use the coating scraper 4 to apply conductive adhesive to the surface of the mesh plate 2, with the conductive adhesive applied through the perforations of the mesh plate 2 onto the housing connector mounting surface. Corresponding screw mounting holes should be made on the mesh plate 2 and the mesh frame 1 to accurately ensure the positioning of the conductive adhesive application.
[0033] The purpose of this invention is to complete the application of conductive adhesive efficiently, conveniently and quickly, while ensuring the consistency of the thickness and shape of the conductive adhesive application.
[0034] like Figure 3As shown, during use, the mesh plate 2 is fixed to the mesh frame 1 using the mesh plate mounting fastener 3. After installation, the mesh frame 1 wraps around the housing connector mounting base on the housing, meaning the inner side of the mesh frame 2 directly contacts the outer side of the structural component, completing the positioning. The holes are arranged in a rectangular array. During use, conductive adhesive is applied to the structural component through the square holes. After application, the connector is installed, with the conductive adhesive between the connector and the structural component. The conductive adhesive is squeezed onto the surface of the mesh plate 2, and the coating scraper 4 is used to scrape back and forth 2-3 times. The conductive adhesive is then applied to the housing connector mounting surface through the mesh plate 2, and excess conductive adhesive is scraped off. After application, the coating tool can be removed.
[0035] Processing method: First, take synthetic stone and process it into a cuboid as the mesh frame 1. The length and width of the cuboid are about 10mm longer than the mounting surface of the shell connector, and the thickness is about 2mm. Take the center of the platform as the center point and deduct the cuboid that matches the shape and size of the mounting surface of the shell connector. Make φ1.5 threaded holes at the four corners of the upper surface of the cuboid for installing the mesh plate mounting fasteners 3, so as to install the mesh plate 2.
[0036] During processing, the surface roughness of the cuboid is below 0.2μm.
[0037] Use a piece of stainless steel about 10mm longer than the mounting surface of the housing connector as the material for mesh plate 2. The dimensions are the same as the mounting surface of the cuboid. Drill holes at the same positions as the cuboid, with a hole diameter of φ1.5.
[0038] Fix the mesh plate 2 to the cuboid mesh frame 1 together using M1.5 screws.
[0039] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
