Description

Technical Field

[0001] The utility model relates to the field of lithium battery detection, in particular to an automatic detection mechanism for the thickness of an insulating layer of a lithium battery. Background Art

[0002] In the insulation layer inspection of lithium batteries, the lithium batteries are generally placed in a predetermined fixture, and then the thickness of the insulation layer is inspected by a detection device. This inspection method includes loading, testing and unloading, so the inspection cycle time is relatively long. In mass production inspection, although the inspection time can be evenly divided by other inspection processes, it also affects the overall inspection efficiency. Therefore, how to design a mechanism that can inspect lithium batteries during transportation is the key to the design, thereby shortening the inspection time of the insulation layer thickness. Utility Model Content

[0003] The main purpose of the utility model is to provide an automatic detection mechanism for the thickness of the insulating layer of a lithium battery, aiming to solve the above technical problems.

[0004] To achieve the above purpose, the utility model proposes an automatic detection mechanism for the thickness of the insulating layer of a lithium battery, comprising:

[0005] A gantry, the gantry comprising two spaced-apart supporting legs and a crossbeam disposed between the upper ends of the two supporting legs;

[0006] A lateral detection device, the lateral detection device comprising a lateral moving device arranged on the crossbeam, a first bracket arranged on the lateral moving device, and a first detector arranged on the first bracket, wherein the first bracket is arranged to extend in an extending direction;

[0007] A top detection device, the top detection device comprising a vertical moving device arranged at the middle of the beam, a second bracket arranged at the vertical moving device, and a second detector arranged at the second bracket;

[0008] When the lithium battery moves to the position of the gantry, the lateral moving device can drive the first detector to abut against the side wall of the lithium battery; at the same time, the vertical moving device can drive the second detector to abut against the top wall of the lithium battery.

[0009] In the actual design, an automatic transport device is provided under the gantry. Therefore, when the lithium battery on the transport device jig passes through the gantry, the top detection device and the lateral detection device respectively detect the insulation layer of the top wall and the insulation layer of the side wall of the lithium battery, thereby avoiding the loading and unloading steps, and the structure is simple, which effectively improves the detection efficiency. Among them, the first detector and the second detector can be set in multiples according to the needs of detection, thereby realizing detection at different positions.

[0022] like Figures 1 to 3 As shown, an automatic detection mechanism for the thickness of the insulating layer of a lithium battery comprises:

[0023] A gantry 1, wherein the gantry 1 comprises two spaced-apart supporting legs 11 and a crossbeam 12 disposed between the upper ends of the two supporting legs 11;

[0027] In the actual design, an automatic transport device is provided under the gantry 1.

[0029] In the embodiment of the utility model, the lateral moving device 2 comprises a lateral guide rail provided on the bottom wall of the beam 12, a lateral slider slidably mounted on the lateral guide rail, and a lateral screw pair driving the lateral slider to move;

[0030] The first bracket 21 is arranged on the transverse slider, thereby realizing a precise stroke of the first detector 22 .

[0031] Specifically, the lateral detection devices are provided in two groups and are arranged opposite to each other.

[0032] In the embodiment of the utility model, the first bracket 21 is provided with at least one group of first positioning holes distributed along its height, and the first positioning holes 41 are used to install the first detector 22. The provision of the first positioning holes 41 facilitates the installation of the first detector 22, and at the same time, the relative position can also be adjusted according to the different sizes or structures of the lithium battery.

[0033] Specifically, the vertical moving device 3 includes a vertical guide rail arranged on the side wall of the beam 12, a vertical slider slidably installed on the vertical guide rail, and a vertical screw pair for driving the vertical slider to move. The second bracket 31 is arranged on the vertical slider, thereby realizing the movement of the second monitor.

[0034] In the embodiment of the utility model, a transverse bracket is provided at the lower end of the second bracket 31 , and the transverse bracket 5 is provided with a plurality of second positioning holes 42 arranged at intervals, and the second positioning holes 42 are used to install the second detector 32 .

[0035] Specifically, the second positioning holes 42 are arranged along the length direction of the transverse bracket, and three second detectors 32 are arranged at intervals.
