Description

Technical Field

[0001] This utility model relates to the field of testing auxiliary fixture technology, specifically a testing auxiliary fixture for conductive metal sheets. Background Technology

[0002] Positive and negative conductive metal sheets are core functional components used in electronic devices, batteries, and other fields to conduct current and connect positive and negative terminals. However, due to their three-dimensional structure, the positive and negative conductive metal sheets are prone to problems such as being unable to be placed directly or being misaligned during the testing process, which affects the accuracy of the test data and the efficiency of the operation. Therefore, it is necessary to design a special auxiliary fixture that is adapted to their three-dimensional characteristics to solve the problem of accurate positioning of non-planar conductive metal sheets during the testing process. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary fixture for testing conductive metal sheets to solve the technical problems in the background art.

[0004] To achieve the aforementioned objectives, this utility model provides the following technical solution:

[0005] A testing auxiliary fixture for conductive metal sheets includes a base with a first through hole and a second through hole arranged side-by-side at an interval. Both the first and second through holes penetrate the upper and lower ends of the base. The base also has a first support plate and a second support plate arranged at an interval. Both the first and second support plates are vertically fixed to the base and span the first and second through holes. The first support plate has a recessed first positioning groove and a second positioning groove, with the first positioning groove above the first through hole and the second positioning groove above the second through hole, and the structures of the first and second positioning grooves are symmetrical. The second support plate has recessed third and fourth positioning grooves, with the third positioning groove behind the first positioning groove and the fourth positioning groove behind the second positioning groove, and the structures of the third and fourth positioning grooves are symmetrical. A support platform is formed between the first and third positioning grooves to support a conductive metal sheet, and another support platform is formed between the second and fourth positioning grooves to support another conductive metal sheet.

[0006] The third positioning groove is provided with a first placement groove, in which a first magnet is installed. The fourth positioning groove is provided with a second placement groove, in which a second magnet is installed. The first magnet and the second magnet have the same structure, both being cylindrical.

[0007] The base has a rectangular structure, and the first through hole and the second through hole have the same structure and are both rectangular.

[0008] The width of the first through hole is greater than the distance between the outer end faces of the first support plate and the second support plate.

[0009] A third magnet is attached above the first magnet, and a fourth magnet is attached above the second magnet. The conductive metal sheet is located below the third and fourth magnets.

[0010] The base, the first support plate, and the second support plate are all made of transparent plastic.

[0011] Compared with the prior art, the conductive metal sheet testing auxiliary fixture of this application has a simple structure and can position and place three-dimensional conductive metal sheets. It uses two magnets to position and clamp the conductive metal sheet, ensuring stable contact during testing and reducing data deviation. The fixture of this application can effectively achieve rapid positioning and placement of conductive metal sheets, thereby improving the product testing efficiency. Attached Figure Description

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Specific Implementation Example 1: Please refer to Figures 1 to 4In this embodiment of the utility model, a conductive metal sheet testing auxiliary fixture includes a base 1. The base 1 has a first through hole 101 and a second through hole 102. The first through hole 101 and the second through hole 102 are arranged side by side with a left-right interval. The first through hole 101 and the second through hole 102 both penetrate the upper and lower ends of the base 1. The base 1 also has a first support plate 2 and a second support plate 3. The first support plate 2 and the second support plate 3 are arranged with a front-to-back interval. The first support plate 2 and the second support plate 3 are both vertically fixed on the base 1. The first support plate 2 and the second support plate 3 both span the first through hole 101 and the second through hole 102. The width W1 of the first through hole 101 is greater than the distance W2 between the outer end faces of the first support plate 2 and the second support plate 3. The base 1, the first support plate 2 and the second support plate 3 are all made of transparent plastic, such as acrylic material. The light transmittance of the material can reach more than 92%, the light is soft and the vision is clear, and the placement state of the conductive metal sheet in the seat and the subtle changes in the testing process can be directly observed, avoiding misjudgment caused by obstruction.

[0018] The first support plate 2 is provided with a recessed first positioning groove 201 and a second positioning groove 202. The first positioning groove 201 is above the first through hole 101, and the second positioning groove 202 is above the second through hole 102. The structures of the first positioning groove 201 and the second positioning groove 202 are symmetrical from left to right. The second support plate 3 is provided with a recessed third positioning groove 301 and a fourth positioning groove 302. The third positioning groove 301 is behind the first positioning groove 201, and the fourth positioning groove 302 is behind the second positioning groove 202. The structures of the third positioning groove 301 and the fourth positioning groove 302 are symmetrical from left to right. A support platform is formed between the first positioning groove 201 and the third positioning groove 301 to support the conductive metal sheet, and another support platform is formed between the second positioning groove 202 and the fourth positioning groove 302 to support another conductive metal sheet. The shapes of the first positioning groove 201, the second positioning groove 202, the third positioning groove 301, and the fourth positioning groove 302 are all matched with the curvature of the product. The two support platform structures formed by the four positioning grooves are just suitable for the positive conductive metal sheet 8 and the negative conductive metal sheet 9. If the two are placed in reverse, they cannot be placed on the corresponding support platform. The position of the conductive metal sheet is fixed by the limiting effect of the grooves to avoid poor contact caused by displacement or tilting during testing.

[0019] The third positioning groove 301 is provided with a first placement groove 301-1, and a first magnet 4 is installed in the first placement groove 301-1. The fourth positioning groove 302 is provided with a second placement groove 302-1, and a second magnet 5 is installed in the second placement groove 302-1. The first magnet 4 and the second magnet 5 have the same structure, both being cylindrical. In order to further improve the stability of product placement, a third magnet 6 is also attracted above the first magnet 4, and a fourth magnet 7 is attracted above the second magnet 5. During actual testing, the conductive metal sheet is positioned between the first magnet 4 and the third magnet 6. In actual use, the magnetic positioning has a "foolproof" operation characteristic. It can be automatically attracted and positioned simply by being roughly close to it, which greatly simplifies the operation steps and reduces the difficulty of operation.

[0020] Compared with the prior art, the conductive metal sheet testing auxiliary fixture of this application has a simple structure and can position and place three-dimensional conductive metal sheets. It uses two magnets to position and clamp the conductive metal sheet, ensuring stable contact during testing and reducing data deviation. The fixture of this application can effectively achieve rapid positioning and placement of conductive metal sheets, thereby improving the product testing efficiency.
