The insulation and voltage resistance test is a technical means for checking and evaluating the insulation performance of a workpiece, and in electrical equipment, the insulation and voltage resistance test needs to be carried out on components in the electrical equipment, so that the normal operation of the components is ensured, and the safety of the electrical equipment is improved.

Taking a battery as an example, the battery generally includes a case and a battery cell, and the battery cell is accommodated in the case. The box body is used for providing accommodating space for the battery monomer, and the battery monomer is used for providing electric energy. The battery may further include a thermal management component (e.g., a water-cooling plate) abutting against the battery cells for adjusting the operating temperature of the battery cells, and the thermal management component may be disposed below the battery cells or sandwiched between the battery cells.

If the thermal management component does not have the insulating property, when the battery cells leak electricity, short circuit may occur between the battery cells under the conduction of the thermal management component, so that potential safety hazards are generated. Therefore, in the assembly process of the battery, the thermal management component needs to be subjected to an insulation withstand voltage test, so that the thermal management component in the battery has insulation performance.

The surface of the thermal management component is typically coated with a glue layer so that the thermal management component can be adhered to the case, and the glue can also serve an insulating effect.

The inventor finds that in the traditional insulation and voltage resistance test process, the heat management component is in contact with insulation and voltage resistance test equipment, the adhesive layer on the surface of the heat management component is bonded with the insulation and voltage resistance test equipment, and the adhesive layer of the heat management component can be damaged when the heat management component is unloaded subsequently. And the glue film damage of the heat management component reduces the viscosity of the glue film on one hand, and then reduces the fixing effect when the heat management component is fixed on the box body, and on the other hand, also reduces the insulating effect of the glue film, and then reduces the insulating effect of the heat management component.

Based on the problems in the prior art, the inventor has conducted extensive studies to design an insulation and voltage resistance test apparatus, which includes two pressing members for electrically connecting with a test mechanism for testing a breakdown voltage of a workpiece, the pressing members including anti-sticking layers configured to cooperatively press the workpiece.

The anti-sticking layer on the pressure applying component separates the pressure applying component from the workpiece, so that the workpiece is prevented from being adhered to the pressure applying component, and the risk of reducing the viscosity of the workpiece caused by the loss of the adhesive layer on the surface of the workpiece in the process of the insulation and voltage resistance test is reduced.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating two pressing members 400 and a workpiece 300 according to some embodiments of the present disclosure, which provides an apparatus 10 for dielectric withstand voltage testing, including two pressing members 400, two pressing members 400 electrically connected to a testing mechanism, the testing mechanism testing a breakdown voltage of the workpiece 300, and a releasing layer included in the pressing members 400, the releasing layer of the two pressing members 400 configured to cooperatively press the workpiece 300.

The testing mechanism is used for testing the breakdown voltage of the workpiece 300, so that the insulation performance of the workpiece 300 can be judged, and the larger the breakdown voltage is, the better the insulation performance of the workpiece 300 is. The testing mechanism can be a withstand voltage tester, and the working principle of the withstand voltage tester is as follows: adding the set voltage to the two ends of the workpiece 300 for a certain time, detecting the leakage current generated by the workpiece 300, and when the value of the leakage current is greater than a preset value, indicating that the insulation of the workpiece 300 fails, wherein the voltage added to the two ends of the workpiece 300 is the breakdown voltage. The structure and operation principle of the pressure tester are common knowledge in the art, and are not described herein.

Taking the workpiece 300 as a water-cooling plate in a battery as an example, a testing mechanism applies voltage to two ends of the water-cooling plate, when the breakdown voltage value reaches a certain value, the thermal management component generates leakage current, and then the insulation performance of the thermal management component can be judged, if the insulation performance of the thermal management component does not meet the requirement of the battery on the insulation performance, the thermal management component needs to be replaced or adjusted. The two ends of the workpiece 300 may be two ends connected to other components when the workpiece 300 is disposed between two other components, for example, a water-cooling plate, which may be sandwiched between two battery cells, and two ends of the water-cooling plate in the thickness direction may be connected between the two battery cells, respectively, and in the process of testing the water-cooling plate, voltage may be applied to the two ends of the water-cooling plate in the thickness direction.

First, the two pressing members 400 have a fixing function, that is, the workpiece 300 is clamped between the two pressing members 400, and the workpiece 300 is fixed to the withstand voltage testing apparatus 10 by the pressing of the pressing members 400; secondly, the pressing members 400 can also perform an electrical connection function, the testing mechanism is electrically connected to the two pressing members 400, and the pressing members 400 can be made of an electrically conductive structure, so that the testing mechanism can apply a voltage to both ends of the workpiece 300 when the pressing members 400 are in contact with the workpiece 300; moreover, the two pressing components 400 can also test the insulation performance of the workpiece 300 under the condition of pressure, so that the state of the workpiece 300 in the actual use process is simulated, the defect that a common pressure tester can only test the insulation performance of the workpiece 300 under the condition of no stress is overcome, and the test accuracy is improved.

The two pressing members 400 press the workpiece 300 in a horizontal direction, and also press the workpiece 300 in a vertical direction. When closed, one pressure applying member 400 may be stationary and the other pressure applying member 400 may be movable. It is also possible that both pressing members 400 are moved toward each other.

The pressing member 400 may be made of a metal material, or a conductive coating 900 may be provided on the surface of the pressing member 400 so that the pressing member 400 has a conductive function.

The anti-sticking layer may be provided on a surface of the pressing member 400 contacting the workpiece 300 to separate the pressing member 400 from the workpiece 300, and the influence of the pressing member 400 on the adhesive force of the workpiece 300 having the adhesive layer on the surface thereof can be reduced by providing the anti-sticking layer. Use work piece 300 as the water-cooling board for example, the surface of water-cooling board can set up the glue film, and the water-cooling board of being convenient for is connected in battery monomer, consequently when carrying out withstand voltage test, needs to test water-cooling board and glue film jointly in order to judge holistic water-cooling board and the holistic insulating part performance of glue film. After the two pressure applying components 400 contact the glue layer of the water-cooling plate, if the pressure applying components 400 do not have anti-sticking performance, the glue layer of the water-cooling plate is adhered to the pressure applying components 400, and after the water-cooling plate is taken down from the pressure applying components 400, part of the glue layer may be separated from the water-cooling plate and adhered to the pressure applying components 400, so that the glue layer of the water-cooling plate is reduced in viscosity, and the subsequent fixing effect of the water-cooling plate is affected. And the thickness of the glue layer is reduced, so that the insulating properties of the water cooling plate and the glue layer are reduced. Therefore, by providing the anti-sticking layer on the pressing member 400, the loss of the adhesive layer on the surface of the workpiece 300 during the dielectric breakdown test can be reduced, and the workpiece 300 can be protected.

The anti-adhesion layer may be provided to be sufficiently applied to each surface of the pressing member 400, or may be applied only to the surface of the pressing member 400 contacting the workpiece 300, and when applied to the surface of the pressing member 400 contacting the workpiece 300, the anti-adhesion layer may be fully applied to the surface, or may be applied only to a portion of the surface.

According to some embodiments of the present application, the anti-sticking layer is a conductive material, and the anti-sticking layer is used for electrically connecting with the testing mechanism.

Since the workpiece 300 and the pressing member 400 are separated by the anti-sticking layer, if the anti-sticking layer is made of an insulating material, the voltage of the pressing member 400 cannot be transmitted to both ends of the workpiece 300, and thus the testing mechanism cannot perform the dielectric breakdown test on the workpiece 300.

The anti-sticking layer made of conductive material enables the voltage generated by the testing mechanism to be transmitted to the workpiece 300, and if the contact area between the anti-sticking layer and the workpiece 300 is small, the insulation defect of the workpiece 300 may be missed to be tested, resulting in inaccurate testing result. The anti-sticking layer is stuck to the workpiece 300, the anti-sticking layer is fully contacted with the workpiece 300, and the risk of missing measurement of the workpiece 300 is reduced.

According to some embodiments of the present application, the release layer is a nickel-based alloy dispersion bonded polymeric release material.

The nickel-based alloy dispersion-bonding polymer anti-sticking material has an anti-sticking function to reduce the risk that the adhesive layer of the workpiece 300 adheres to the pressing member 400, and has a conductive function to transmit the voltage of the testing mechanism to the two ends of the workpiece 300 through the anti-sticking layer.

According to some embodiments of the present application, referring to fig. 1, the pressing member 400 further includes a base layer 403, and the release layer is a coating 900 coated on a surface of the base layer 403.

The base layer 403 may be a plate-shaped body, for example, the base layer 403 may be a circular plate body, and the base layer 403 may also be a rectangular, triangular or other polygonal plate body.

The coating 900 may be formed by coating on the surface of the base layer 403, or by spraying on the base layer 403.

By applying a release material to the surface of the base layer 403, a release layer may be formed on the surface of the base layer 403.

Referring to fig. 1 and 2, fig. 2 is a schematic structural diagram of an apparatus 10 for dielectric withstand voltage test according to some embodiments of the present disclosure, in which two pressing members 400 include a first pressing member 402 and a second pressing member 401, and the first pressing member 402 is used for supporting a workpiece 300 along a first direction.

The first direction may be a direction indicated by a Z axis in the drawing, and in the present embodiment, the first direction may be a vertical direction, that is, the first pressing member 402 and the second pressing member 401 are disposed opposite to each other in the vertical direction.

The workpiece 300 may be placed on the first pressing member 402 such that the first pressing member 402 can support the workpiece 300, and when the second pressing member 401 moves toward the first pressing member 402, the first pressing member 402 and the second pressing member 401 can generate pressing forces to the workpiece 300, thereby fixing the workpiece 300 between the first pressing member 402 and the second pressing member 401 on the one hand, and pressing the workpiece 300 by the first pressing member 402 and the second pressing member 401 on the other hand, so that the testing mechanism can test the insulating properties of the workpiece 300 in a pressed state.

Under the action of the first driving mechanism 700, the second pressing member 401 can move towards the first pressing member 402 and also move away from the first pressing member 402, so as to facilitate loading and unloading operations on the first pressing member 402.

The pressure detecting element can measure the pressure applied to the workpiece 300 by the first driving mechanism 700 so as to accurately simulate the stress condition of the workpiece 300 during actual use. In this embodiment, the pressure detecting unit 609 may be a pressure sensor, which is electrically connected to the processor, and the data measured by the pressure sensor is fed back to the user through the processor.

The second connector 602 and the third connector 601 are floatably connected such that when the second pressing member 401 does not contact the workpiece 300, the distance between the second connector 602 and the third connector 601 is the largest, and at this time, a gap exists between the measuring end of the pressure detecting unit 609 and the nearest connector, and the pressure value measured by the pressure detecting unit 609 is zero. When the second pressing member 401 contacts the workpiece 300, the distance between the second link 602 and the third link 601 decreases by the first driving mechanism 700, and the measurement end of the pressure detection unit 609 starts to measure the pressure value. The reduced pressure detection unit 609 starts measurement when the first pressing portion and the second pressing portion have not come into contact, resulting in a risk of measurement inaccuracy.

For example, the pressure detecting unit 609 may be connected to the second connecting member 602, a measuring end of the pressure detecting unit 609 faces the third connecting member 601, when the second pressing member 401 does not contact the workpiece 300, a distance between the second connecting member 602 and the third connecting member 601 is the largest, a gap exists between the measuring end of the pressure detecting unit 609 and the third connecting member 601, and a pressure value measured by the pressure detecting unit 609 is zero. When the second pressing member 401 contacts the workpiece 300, the distance between the second link 602 and the third link 601 decreases by the first driving mechanism 700, and the measurement end of the pressure detection unit 609 starts to measure the pressure value.

The pressure detecting unit 609 can also be connected to the third connecting member 601, the measuring end of the pressure detecting unit 609 faces the second connecting member 602, when the second pressing member 401 does not contact the workpiece 300, the distance between the second connecting member 602 and the third connecting member 601 is the largest, a gap exists between the measuring end of the pressure detecting unit 609 and the third connecting member 601, and the pressure value measured by the pressure detecting unit 609 is zero. When the second pressing member 401 contacts the workpiece 300, the distance between the second link 602 and the third link 601 decreases by the first driving mechanism 700, and the measurement end of the pressure detection unit 609 starts to measure the pressure value.

If the second connecting member 602 and the third connecting member 601 are fixedly connected, when the second pressing member 401 does not contact the workpiece 300, the pressure detecting unit 609 may detect a pressure value under the pressing action of the second connecting member 602 and the third connecting member 601, which may result in a larger pressure value being detected when the subsequent second pressing member 401 contacts the workpiece 300.

In this embodiment, an abutting member may be further disposed between the third connecting member 601 and the second connecting member 602, and the abutting member includes a convex surface, and the convex surface faces the measuring end of the pressure detecting unit 609. For example, when the pressure detecting unit 609 is connected to the second connector 602, an abutment may be provided at the third connector 601, the convex surface of the abutment facing the measuring end of the pressure detecting unit 609. In case, for example, the pressure detecting unit 609 is connected to the third connecting part 601, an abutment may be provided to the second connecting part 602, the convex surface of the abutment facing the measuring end of the pressure detecting unit 609. The convex surface of the abutment reduces the contact area of the abutment and the pressure detection unit 609, improving the sensitivity of the pressure detection unit 609 measurement. The abutment may be a ball stud, the ball of which faces the measuring end of the pressure detection unit 609.

If the maximum distance L between the pressure detecting element and the second connecting member 602 is set ₁ Less than 0.03mm due to L ₁ If the value is too small, it is difficult to adjust the distance between the second connector 602 and the third connector 601 ₁ Greater than 0.07mm, the stroke of the first driving mechanism 700 driving the second pressing member 401 is increased, which both reduces the measurement efficiency and increases the energy consumption.

When L is ₁ L is more than or equal to 0.03mm ₁ And when the distance is less than or equal to 0.07mm, the risk that the pressure detection unit 609 starts measuring when the first pressing part and the second pressing part are not contacted yet can be reduced, so that the measurement is inaccurate, and the stroke of the first driving mechanism 700 for driving the second pressing component 401 is not excessively increased.

Provided that the maximum distance L between the pressure detecting element and the third connecting member 601 ₂ Less than 0.03mm due to L ₂ Too small a value makes it difficult to adjust the spacing between the second connector 602 and the third connector 601, provided that L is ₂ Greater than 0.07mm, the stroke of the first driving mechanism 700 driving the second pressing member 401 is increased, i.e.The measuring efficiency is reduced, and the energy consumption is increased.

When L is ₂ L is more than or equal to 0.03mm ₂ When the thickness is less than or equal to 0.07mm, the risk that the pressure detection unit 609 starts measurement when the first pressing part and the second pressing part are not in contact yet can be reduced, so that measurement is inaccurate, and the stroke of the first driving mechanism 700 for driving the second pressing part 401 is not excessively increased.

According to further embodiments of the present application, L ₂ =0.05mm。

When L is ₂ Equal to 0.05mm, compared with L ₂ When =0.03, the distance between the second link 602 and the third link 601 is made easier to adjust, and the stroke of the first driving mechanism 700 for driving the second pressing member 401 is not excessively increased.
