Description

Technical Field

[0001] This utility model relates to the field of electronic component manufacturing and testing technology, specifically to a conductive sheet and a testing tool. Background Technology

[0002] In the manufacturing process of electronic devices, conductive sheets are key components for achieving electrical connections, and their performance and quality directly affect the overall operational stability of the equipment. Conductive sheets are typically used to establish reliable conductive paths between different electronic components, ensuring smooth current transmission. Traditionally, the methods for inspecting these conductive sheets are relatively outdated. Inspection methods mostly rely on manual visual inspection, depending on the inspector's experience to judge whether the appearance and dimensions of the conductive sheet are up to standard, or on using calipers to measure various dimensions of the conductive sheet. Inspecting multiple dimensions requires significant time investment in the inspection of individual conductive sheets.

[0003] During the testing process, the conductive sheet corresponding to this application, such as Figure 1 As shown, the conductive sheet includes a pair of mounting pieces 1, a connecting piece 2, and a bent piece 3. The pair of mounting pieces 1 are arranged in parallel and have a pair of mounting holes 11. The connecting piece 2 is located between the pair of mounting pieces 1. The bottom edge 12 of the mounting piece 1 is connected to the first side edge 21 of the connecting piece 2. The connecting piece 2 is perpendicular to the mounting piece 1. The bent piece 3 is connected to the second side edge 22 of the connecting piece 2. The second side edge 22 is away from the mounting piece 1 and perpendicular to the first side edge 21 and the bottom edge 12. For the above-mentioned conductive sheet, due to its own structural characteristics, the traditional method is to measure the dimensions of 30 parts of the conductive sheet with calipers. The inspection is time-consuming and inefficient. Therefore, a new type of inspection tool is needed to quickly inspect the conductive sheet and improve the inspection efficiency. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide a conductive sheet inspection fixture. Through the unique design of the pin and inspection platform structure of the fixture, the conductive sheet can be quickly embedded into the groove of the inspection platform and accurately positioned. It is only necessary to measure the key dimension of the distance from a specific part of the bent sheet to the inspection platform to determine whether the conductive sheet is qualified, which greatly reduces the number of inspection parts. At the same time, the conductive sheet structure is optimized to adapt to the inspection fixture, thereby significantly improving the inspection efficiency.

[0005] Technical solution: The utility model provides a conductive sheet, which includes a pair of mounting sheets, a connecting sheet and a bending sheet. The pair of mounting sheets are arranged in parallel, and a pair of mounting holes are provided thereon. The connecting sheet is arranged between the pair of mounting sheets. The bottom edge of the mounting sheet is connected to the first side edge of the connecting sheet. The connecting sheet is perpendicular to the mounting sheet. The bending sheet is connected to the second side edge of the connecting sheet. The second side edge is away from the mounting sheet and perpendicular to the first side edge and the bottom edge. A pair of mounting sheets arranged in parallel and provided with mounting holes can stably fix the conductive sheet at a specific position of the electronic device through connecting parts such as bolts and rivets, ensuring that the conductive sheet will not be easily displaced during the operation of the device and ensuring the stability of the electrical connection.

[0006] Further, in a conductive sheet inspection tool of the present application, the connecting sheet is in a convex shape, and the bending sheet extends downward along the convex part of the convex shape.

[0007] Further, in a conductive sheet inspection tool of the present application, the bending sheet includes a first bending part and a second bending part. The first bending part is connected to the convex part of the convex shape, and the second bending part is connected to the first bending part to form an overall S shape. The arc radius of the first bending part is greater than the arc radius of the second bending part. The unique S-shaped design enables the bending sheet to have stronger adaptability in the complex spatial layout inside the electronic device.

[0008] An inspection tool for compliance inspection of the above-mentioned conductive sheet includes a pair of pin posts and an inspection table. The inspection table is in an overall concave shape and has a groove thereon. The conductive sheet is arranged in the groove. The groove is composed of a bottom surface and a pair of side surfaces. The pair of side surfaces are arranged in parallel and perpendicular to the bottom surface. A pair of inspection holes are provided on the side surfaces. When the conductive sheet is inserted into the groove without interference, the inspection holes correspond to the mounting holes, the mounting sheet abuts against the corresponding side surface, and the pin posts can be completely inserted into the mounting holes and the inspection holes. Then, use a caliper to measure the distance from the end of the second bending part of the bending sheet to the inspection table. If the distance meets the tolerance, the conductive sheet is qualified. Different specifications of conductive sheets correspond to different distances. The concave-shaped groove design of the inspection table can enable the conductive sheet to be quickly and accurately inserted therein, and the side surface abuts against the mounting sheet to achieve preliminary fixation. The correspondence between the inspection holes and the mounting holes and the cooperation of the pin posts can quickly judge whether the position accuracy and size of the mounting holes meet the standards. If the cooperation is not smooth, it can be directly determined that the conductive sheet has defects in this regard, completing the preliminary screening. After the above preliminary inspection, the measurement of the distance from the end of the second bending part of the bending sheet to the inspection table is for the detection of the key part dimensions of the conductive sheet. Since different specifications of conductive sheets correspond to different distance standards, by measuring this distance with a caliper and comparing it with the tolerance, it can accurately judge whether the overall structural dimensions of the conductive sheet meet the corresponding specification requirements, comprehensively detecting the quality of the conductive sheet.

[0009] Furthermore, in one inspection tool of this application, the front end of the pin extends axially with a truncated cone, which is used for rapid insertion into inspection holes and mounting holes. The truncated cone structure at the front end of the pin plays a guiding role during insertion into the inspection and mounting holes. Because the truncated cone is conical, its smaller end enters the hole first, automatically aligning with the center of the hole, helping the pin to be inserted accurately. This reduces insertion difficulties caused by hole position deviation or inaccurate pin insertion angle, ensuring that the pin can quickly and accurately engage with the inspection and mounting holes.

[0010] Furthermore, in one inspection fixture of this application, the end of the pin furthest from the truncated cone is provided with a stop portion. The diameter of the stop portion is larger than the diameter of the pin, which is used to limit the pin when it is inserted into the inspection hole, preventing the pin from sliding to one side and falling off. Since the diameter of the stop portion is larger than that of the pin, after the pin is inserted into the inspection hole, the stop portion can abut against the side of the inspection table, restricting the pin from further insertion or sliding to one side. This ensures that the pin remains in the correct position throughout the inspection process. If the pin is not restricted during the inspection, it may slip out of the inspection hole due to vibration, misoperation, or other reasons. The stop portion effectively prevents this from happening, ensuring that the pin remains engaged with the inspection hole and mounting hole until the inspection is completed, avoiding interruption of the inspection process due to the pin falling off and affecting the continuity of the inspection.

[0011] As can be seen from the above technical solution, this utility model has the following beneficial effects:

[0012] 1. The conductive sheet inspection fixture of this utility model achieves stable installation, efficient conductivity, and flexible adaptation through a unique combination structure design of mounting plates, connecting plates, and bending plates. The parallel mounting plates with mounting holes ensure stable installation, the vertical connecting plates optimize the current conduction path, and the bending plates adapt to complex spatial layouts, thus improving the versatility and electrical performance stability of the conductive sheet in different electronic devices.

[0013] 2. The conductive sheet inspection fixture described in this utility model significantly improves inspection efficiency and accuracy through its pin-shaped structure, inspection platform, and targeted inspection process. The U-shaped groove of the inspection platform enables rapid and precise positioning of the conductive sheet. The pin, in conjunction with the inspection hole and mounting hole, completes preliminary screening. Measuring the spacing at specific locations on the bent sheet determines the overall quality, reducing the number of inspection points and time. The cone-shaped design of the pin improves insertion efficiency and ensures stable inspection processes, reducing operational difficulty and adapting to the inspection of various conductive sheet specifications, thus enhancing the reliability and versatility of the fixture.

Detailed Implementation

[0021] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] This embodiment takes the conductive sheet used in the production of a certain type of electronic device as an example to explain in detail the application process of the conductive sheet and inspection tool of this utility model.

[0024] like Figure 1 , 2 As shown in Figure 3, firstly, a batch of conductive sheets conforming to the design of this utility model are prepared. A pair of mounting pieces 1 of the conductive sheet are arranged in parallel, and each mounting piece 1 has a pair of mounting holes 11. The positional accuracy and dimensional tolerance of these mounting holes 11 are strictly processed according to the design standards. A connecting piece 2 is convex in shape and located between the pair of mounting pieces 1. The bottom edge 12 of the mounting piece 1 is firmly connected to the first side edge 21 of the connecting piece 2, and the connecting piece 2 is perpendicular to the mounting piece 1. A bent piece 3 is connected to the second side edge 22 of the connecting piece 2 and extends downward along the convex part of the convex shape. It includes a first bent part 31 and a second bent part 32, and is generally S-shaped. The radius of the arc of the first bent part 31 is larger than the radius of the arc of the second bent part 32.

[0025] Next, as Figure 4 , 5, as shown in FIGS. 6, the inspection tool of the present utility model is used to inspect this batch of conductive sheets. The inspection table 5 of the inspection tool is integrally concave-shaped. The groove 51 is composed of a bottom surface 511 and a pair of side surfaces 512 that are parallel and perpendicular to the bottom surface 511. A pair of inspection holes 5121 are provided on the side surface 512. The front end of the pin column 4 is provided with a frustum 41, and the rear end is provided with a stop portion 42. The diameter of the stop portion 42 is larger than that of the pin column 4.

[0026] During inspection, a conductive sheet to be inspected is smoothly embedded into the groove 51 of the inspection table 5. Due to the design of the groove 51 being adapted to the conductive sheet, the conductive sheet can be smoothly embedded without interference. At this time, it is observed that the mounting piece 1 is closely abutted against the corresponding side surface 512, and the mounting hole 11 is precisely aligned with the inspection hole 5121. Pick up the pin column 4, align the end with the frustum 41 with the mounting hole 11 and the inspection hole 5121. The frustum 41 plays a guiding role, and the pin column 4 can be easily and quickly inserted into the two holes. The stop portion 42 abuts against the side surface of the inspection table 5, effectively preventing the pin column 4 from further penetrating or sliding to one side.

[0027] Then, use a caliper to measure the distance 6 from the end of the second bending portion 32 of the bending piece 3 to the inspection table 5. If the distance 6 is within the tolerance range, it is determined that the conductive sheet is qualified. According to the same process, other conductive sheets in this batch of conductive sheets are inspected one by one. It should be noted that Figure 5 There are two specifications of conductive sheets. The difference lies in the different distances 6. Therefore, this similar type of conductive sheet can all be inspected using the inspection tool of the present utility model, and it has a certain degree of generality.

[0028] During the entire inspection process, due to the reasonable structural design of the conductive sheet of the present utility model, when installed in an electronic device, it can be firmly fixed at the specified position of the device by using bolts through the mounting holes 11 on the mounting piece 1, ensuring stable electrical connection. And the design of the inspection tool makes the inspection process efficient and accurate. Compared with the traditional inspection method, the time for inspecting each conductive sheet is greatly shortened, greatly improving the inspection efficiency. At the same time, it reduces the errors caused by manual inspection of multiple dimensions, improves the product quality, and ensures the stable operation of the electronic device.

[0029] The above embodiments are exemplary. The purpose is to illustrate the technical concept and characteristics of the present utility model so that those familiar with this field can understand the content of the present utility model and implement it accordingly. The protection scope of the present utility model cannot be limited by this. All equivalent changes or modifications made according to the spirit and essence of the present utility model should be covered within the protection scope of the present utility model.
