Specifically, the part to be tested of the insulation and voltage withstanding test device 100 for testing is a lithium battery 200, and the part to be tested of the part to be tested is a battery cell 201 (see fig. 2) included in the lithium battery 200.

Referring to fig. 1, 3 and 4, the insulation and voltage withstanding test apparatus 100 includes a transfer module 10, a mounting member 20, at least two floating plates 30, an elastic member 40 and a probe 50. The mounting member 20 is mounted on the transfer module 10, an elastic member 40 is disposed between each floating plate 30 and the mounting member 20, and a probe 50 is mounted on each floating plate 30. Specifically, the probe 50 is an elastic probe having elasticity. That is, the probe 50 can compress a certain size by itself when contacting with the battery cell 201, so that the probe 50 contacts closely with the battery cell 201, and the electrical connection effect is ensured.

The insulation voltage withstanding test device 100 further comprises a detection mechanism, when the transfer module 10 drives the floating plate 30 to move through the mounting piece 20, and the floating plate 30 can generate relative movement with the mounting piece 20 when receiving the first acting force applied to the battery core 201 through the probe 50 in the process of pressing the battery core 201 by the probe 50, the elastic piece 40 elastically deforms and stores energy, and the detection mechanism can detect the floating plate 30 generating relative movement with the mounting piece 20 and output signals.

Since the mounting member 20 continues to move close to the battery cell 201 under the action of the transfer module 10, other floating plates 30 can not generate relative movement with the mounting member 20 due to normal compression deformation of the probe 50, the floating plate 30 provided with the damaged and jammed probe 50 receives a first acting force and compresses the elastic member 40, the elastic member 40 elastically deforms and stores energy, relative movement is generated between the floating plate 30 and the mounting member 20, and the detection mechanism stops pressing down by detecting the floating plate 30 generating relative movement with the mounting member 20 and outputting a signal, so that the battery cell 201 is prevented from being damaged; and can determine which probe 50 on the floating plate 30 is stuck, facilitating quick determination of the fault location.

The first direction, the second direction and the third direction intersect each other two by two, specifically, the first direction, the second direction and the third direction are perpendicular to each other two by two. The first direction is the Y direction in FIG. 1, the second direction is the X direction in FIG. 1, and the third direction is the Z direction in FIG. 1. More specifically, when the insulation voltage testing apparatus 100 is the piezoelectric core 201 in the vertical direction, the above-described third direction is the vertical direction.

In the above arrangement, when the insulation and voltage withstanding test device 100 detects the lithium battery 200, the triaxial transfer mechanism 11 adjusts the positions of the probe 50 in the first direction, the second direction and the third direction, and the rotating mechanism 12 can drive the probe 50 to rotate so as to adjust the angle of the probe 50 in the plane perpendicular to the third direction, so that the probe 50 is opposite to the conducting area of the battery cell 201, and the positioning effect of the probe 50 and the conducting area is ensured (see fig. 6 and 7).

Further, with continued reference to fig. 1 and 5, the triaxial transfer mechanism 11 includes a first linear module 111, a second linear module 112 and a third linear module 113, the second linear module 112 is mounted on the first linear module 111, the third linear module 113 is mounted on the second linear module 112, and the rotating mechanism 12 is mounted on the third linear module 113.

In some embodiments, with continued reference to fig. 1, the insulation and voltage withstand test apparatus 100 further includes a vision module 60, wherein the vision module 60 is mounted on the transfer module 10, and specifically, the vision module 60 is mounted on the rotating mechanism 12. The vision module 60 is used for shooting the lithium battery 200, and the transfer module 10 can adjust the position of the probe 50 according to the shooting result of the vision module 60, so that the probe 50 is aligned with the lithium battery 200, that is, the conducting area of the probe 50 and the battery cell 201 is aligned, so as to achieve the purpose of accurate positioning. In some embodiments, the vision module 60 is a CCD camera.

In some embodiments, with continued reference to fig. 3, the insulation and voltage withstand test apparatus 100 includes at least two floating plate sets 70 arranged sequentially in a first direction, each floating plate set 70 including at least two floating plates 30 arranged sequentially in a second direction. In this way, since the probes 50 are mounted on each floating plate 30, the insulation and voltage withstand test apparatus 100 includes more probes 50 so as to detect more cells 201.

In some embodiments, the detecting mechanism includes a matching member 91 and a detecting member 92, where each floating plate 30 is provided with the matching member 91, and the detecting member 92 is provided on the mounting member 20. The detecting member 92 is capable of detecting the mating member 91 provided on the floating plate 30 to detect the floating plate 30 that generates a relative movement with the mounting member 20 and output a signal. Thus, when the floating plate 30 and the mounting member 20 move relatively, the detecting member 92 can detect whether the floating plate 30 moves relative to the mounting member 20 by detecting the mating member 91 connected to the floating plate 30, so as to achieve the purpose of detecting whether the probe 50 mounted on the floating plate 30 is jammed.

Further, the mating member 91 is an inductive piece, and the detecting member 92 includes a transmitting portion 921 and a receiving portion 922 that are disposed at intervals.

That is, when the probe 50 is locked, the floating plate 30 with the probe 50 mounted thereon moves relative to the mounting member 20, and at this time, a relative movement occurs between the fitting member 91 and the detecting member 92, and when the fitting member 91 moves between the transmitting portion 921 and the receiving portion 922, that is, when the fitting member 91 moves to block the light emitted from the transmitting portion 921 from being transmitted to the receiving portion 922, the device stops pressing down and the detecting member 92 sends a signal, so that the controller can determine which probe 50 is locked.

It should be understood that in other embodiments, the detection mechanism may be provided in other ways, as long as the purpose of detecting the floating plate 30 that moves relative to the mounting member 20 to detect which probe 50 is stuck is achieved, which is not limited herein.

In this way, the floating plate 30 and the detecting member 92 are easily installed.

Optionally, with continued reference to fig. 7, the mounting plate 21 is provided with a through hole 211, and one end of the mating member 91 is connected to the floating plate 30, and the other end is disposed through the through hole 211. When the floating plate 30 and the mounting member 20 move relatively, the detecting member 92 can detect the penetrating end of the fitting member 91 penetrating the penetrating hole 211 to output a signal. That is, when the floating plate 30 moves relative to the mounting plate 21, the engaging member 91 can move in the through hole 211, and when the exit end of the engaging member 91 moves between the emitting portion 921 and the receiving portion 922, the detecting member 92 outputs a signal when the light emitted from the emitting portion 921 is blocked from being transmitted to the receiving portion 922, and the controller determines that the probe 50 mounted on the floating plate 30 is stuck.

The transfer module 10 drives the probe 50 to move downwards, if the probe 50 is normal in the process of pressing the lithium battery 200 by the probe 50, the probe 50 can be compressed by a certain size (for example, 3 mm), and after the pressure is relieved, the probe 50 rebounds to an initial state. If the probe 50 is damaged and stuck, the probe 50 cannot be compressed, and then the corresponding floating plate 30 is stopped in place and cannot be moved after the probe 50 contacts the battery cell 201 in the process that the third linear module 113 of the transfer module 10 drives the probe 50 to press the lithium battery 200. The engaging piece 91 is mounted on the floating plate 30, and the engaging piece 91 mounted on the floating plate 30 is not moved downward. The mounting member 20 continues to move downward and the cell 201 applies a first force to the floating plate 30 through the probe 50, under which the elastic member 40 compresses. The detecting member 92 on the mounting member 20 moves down, the fitting member 91 shields the light emitted from the emitting portion 921, the insulation and voltage withstand test device 100 stops pressing down and starts alarming, damage to the battery cell 201 is avoided, and it can be judged which probe 50 on the floating plate 30 is stuck, which is advantageous for quick determination of the fault position.
