Description

Technical Field

[0001] The utility model belongs to the technical field of lithium-ion battery manufacturing, and particularly relates to an electrical inspection tooling for a circular small polymer terminal type battery. Background Art

[0002] At present, circular small polymer terminal type batteries are increasingly used in various portable mobile device fields, such as electronic pens, Bluetooth headsets, electronic cigarettes, etc. As the volume of electronic products becomes smaller and smaller, it is required that the battery volume becomes smaller and smaller. The smaller positive and negative electrode lead-out terminals on the PCM require suppliers to have accurate and efficient electrical inspection methods for circular small polymer terminal type batteries. Since the circular small polymer terminal type battery itself is not a standard cylindrical structure, the top and the battery body are sometimes not at 90°, and the area of the head terminal is too small. It is difficult to load and unload the battery with the commonly used electrical inspection tooling, difficult to scan the code, and the contact position between the probe and the terminal is not easy to observe, which affects the debugging effect.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0018] In the description of the present invention, it should be noted that, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixed connection", "fixed connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. The specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0019] As Figure 1As shown in the figure, an electrical inspection tooling for a circular small polymer terminal type battery includes a base 10, a linear guide rail 20, a battery support plate 30, a probe mounting plate 40 and test probes 60. The test probes are installed on the side of the probe mounting plate and correspond to the battery support plate. The bottom of the battery support plate is slidably matched with the linear guide rail and can move back and forth along the linear guide rail 20 after being subjected to a thrust force, driving the battery 80 to move. The linear guide rail is fixed on the base, and the probe mounting plate is fixed on the base and located at one end of the linear guide rail.

[0020] Specifically, in order to be able to limit the battery, a positioning groove 90 for positioning the battery is provided on the battery support plate. The battery support plate 30 is designed with a profiling structure. After the battery 80 is placed in the battery support plate 30, it will not roll over. After contacting the test probe 60, the positioning posts on both sides of the battery are also clamped by the battery support plate 30 and cannot move backward. Further, in order to facilitate the removal of the battery in the positioning groove, a taking groove 100 is provided on one side of the positioning groove. The taking groove extends inward from the side of the battery support plate, and the worker can take out the battery from the bottom of the positioning groove through the taking groove. Further, in order to make the front end of the circular small polymer terminal type battery contact the probe protection plate, a groove 110 is provided at the front end of the battery support plate. The front end of the battery support plate first contacts the probe protection plate, causing the probe protection plate to squeeze the spring pressure pin, exposing the test probe. The test probe passes through the groove 110 to contact the positive and negative electrodes of the battery to test the battery.

[0021] Further, two spring pressure pins are installed on the probe mounting plate. The two spring pressure pins are located on both sides of the test probe. The outer ends of the two spring pressure pins are fixed with a probe protection plate, and through holes corresponding to the test probes are provided on the probe protection plate. When not being squeezed, it will completely block and protect the test probe 60. After the probe protection plate 70 is squeezed by the battery support plate 30, it will move towards the probe mounting plate 40, exposing the test probe 60 to test the battery 80.

[0022] During use, after the battery 80 is placed in the battery support plate 30, the employee can push the battery support plate 30 by hand to drive the battery 80 to contact the test probe 60. And since the spring pressure pin 50 will absorb part of the thrust force, the battery 80 is not easily damaged by the test probe 60.

[0023] It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
