Description

Technical Field

[0001] The utility model relates to the technical field of automated production, in particular to an auxiliary tooling device for lithium battery utility detection. Background Art

[0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time in the past. However, with the development of science and technology, lithium batteries have now become mainstream and are widely used in mobile phones and other electronic products.

[0003] In the processing of lithium batteries, it is necessary to perform on-off detection on the finished lithium batteries, that is, to detect whether the battery can discharge and conduct. The traditional on-off detection of lithium batteries is generally done by manually connecting a multimeter to the positive and negative poles of the battery, and then making a judgment based on the data displayed on the multimeter.

[0004] This method of manually replacing batteries one by one and connecting the positive and negative poles of the batteries not only has low test efficiency, but the probes on the multimeter can easily scratch the electrodes on the batteries, resulting in reduced production quality. This working method of manually replacing batteries one by one for testing obviously cannot meet the needs of large-scale testing. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide an auxiliary tooling device for lithium battery utility detection, which has a simple structure and layout and replaces the traditional method of frequently replacing batteries and connecting battery electrodes manually.

[0008] Two displacement seats are respectively connected to the transverse slide, and the displacement seats are provided with inwardly extending detection probes for detecting polarity of lithium batteries;

[0009] The middle seat is arranged on the top of the base and is located in the center of the two displacement seats. A contour seat for lying lithium batteries is installed on the surface of the middle seat, and the detection probe faces the direction of the contour seat.

[0010] According to the auxiliary tooling device for lithium battery utility detection provided by the utility model, the surface of the profiling seat is concave along its length direction to form an arc-shaped placement groove. The designed arc-shaped placement groove can adapt to lithium batteries of different models and diameters, and has wide applicability.

[0011] Furthermore, a replaceable seat is provided on the surface of the profiling seat, the replaceable seat is detachably connected to the profiling seat, and the back of the replaceable seat fits the arc-shaped placement groove, and the surface of the replaceable seat is recessed along its length direction to form an arc-shaped outer placement groove. The designed replaceable seat can be replaced to adapt to the use of lithium batteries of other models and lengths, so that the profiling seat does not need to be repeatedly replaced when detecting lithium batteries of different lengths.

[0012] Furthermore, a plug hole is provided at the center of the replaceable seat, and a screw hole is provided at the center of the surface of the contoured seat, the screw hole corresponds to the position of the plug hole, and the screw hole and the plug hole are connected by screws. The screw connection method is simple and convenient to install, and only requires drilling, and can be completed without complex tools, saving labor costs.

[0013] Furthermore, the middle positions of the two sides of the profiling seat and the replaceable seat are respectively provided with a first notch and a second notch, and the second notch overlaps with the first notch. The first notch and the second notch are designed to facilitate the staff to quickly take the battery from the middle after the test, thereby improving the replacement efficiency.

[0014] According to the auxiliary tooling device for lithium battery utility detection provided by the utility model, guide rails are provided between the two sides of the middle seat and the side walls of the base, and the displacement seat is movably mounted on the guide rails in a snap-fit ​​manner. The displacement seat and the guide rails are slidably matched to ensure the position accuracy of the displacement seat during the left and right movement, thereby ensuring the position accuracy of the detection probe test.

[0015] Compared with the prior art, the utility model has the following technical effects: the utility model has a simple structure and a reasonable design. By setting a bidirectional slide cylinder, a displacement seat, a detection probe, and a contour seat, it can replace the manual frequent replacement of batteries and the detection operation of connecting the positive and negative poles of the batteries. Manual personnel only need to directly put the batteries on the contour seat, and the bidirectional slide cylinder can realize the automatic connection operation between the detection probe on the displacement seat and the positive and negative poles of the battery, effectively improving the detection efficiency and detection accuracy, and reducing the workload of operators.

The embodiment of the utility model proposes an auxiliary tooling device for lithium battery utility detection, including a base 1, the interior of the base 1 is hollow and the top is open, the interior of the base 1 is provided with a two-way slide cylinder 2, the two-way slide cylinder 2 has two lateral slides 21 that can move synchronously laterally, the two-way slide cylinder is a standard part, and can realize that the left and right lateral slides are synchronously moved together or separated to both sides; two displacement seats 3, respectively connected to the lateral slide 21, and the displacement seats 3 are provided with inwardly extending detection probes 4 for polarity detection of lithium batteries, the detection probes are also standard parts, which are connected to external electrical test instruments such as multimeters through wires; the middle seat 5 is arranged on the top of the base 1 and is located in the center of the two displacement seats 3, the surface of the middle seat 5 is installed with a contour seat 6 for lying lithium batteries, and the detection probe 4 faces the contour seat 6.

[0023] The auxiliary tooling is very simple to use. The staff places the lithium battery to be tested horizontally on the contour seat 6, and the two-way slide cylinder part 2 controls the two displacement seats 3 to move closer to the contour seat 6 until the detection probes 4 on the displacement seats 3 respectively contact the positive and negative electrodes of the lithium battery to be tested, thereby completing the discharge conduction of the positive and negative electrodes of the lithium battery to be tested. After that, the staff observes the external electrical testing instrument to make a benign judgment; after the test is completed, the two-way slide cylinder part 2 controls the two displacement seats 3 to separate in the direction away from the contour seat 6, the staff removes the lithium battery on the contour seat 6, and puts in a new lithium battery to be tested, and repeats the above process.

[0024] In one embodiment, the surface of the contour seat 6 is recessed along its length direction to form an arc-shaped placement groove 61. The arc-shaped placement groove is designed to fit lithium batteries of different models and diameters, and has wide applicability.

[0025] Based on the above scheme, a replaceable seat 7 is also provided on the surface of the profiling seat 6, and the replaceable seat 7 is detachably connected to the profiling seat 6, and the back of the replaceable seat 7 is fitted with the arc-shaped placement groove 61, and the surface of the replaceable seat 7 is recessed along its length direction to form an arc-shaped outer placement groove 71.
