Description

Technical Field

[0001] The present application relates to the technical field of testing instruments, and in particular to a short circuit testing device. Background Art

[0002] The short-circuit test device is usually used to perform a short-circuit test on the test target. For example, before a power battery is put into use, it is usually necessary to perform a short-circuit test on it to ensure its performance.

[0003] At present, in the process of short-circuit testing of the test target, static electricity on the test target and static electricity in the air around the test target are likely to affect the short-circuit test. Especially for the short-circuit test of power batteries, the commonly used testing methods are pulse type, insulation type or a combination of the two. According to research, after the battery is baked, there is a certain gap between the shell and the surface of the battery. When the surface is damaged, it cannot be accurately tested. If a certain pressure is applied to the surface to eliminate the gap, as the air is discharged, the airflow will also take away the scattered graphite dry powder inside the battery, which will affect the test results; if static electricity is generated during the production process, it will also affect the test results, resulting in a reduction in production yield, among which the pulse type is particularly sensitive to current.

[0004] Therefore, the test accuracy of the current short-circuit test device is not high enough. Utility Model Content

[0011] The above-mentioned short-circuit test device, by making the long edges of the air outlet edges opposite to each other parallel to the plane of the surface of the test target exposed outside the receiving mechanism, allows the ion wind output by the ion blower to pass through the test target to the greatest extent, thereby improving the efficiency of static electricity removal.

[0012] Optionally, the test machine body further includes a sliding mechanism and a probe; the probe is slidably connected to the frame via the sliding mechanism; the probe is configured to move toward the received test target via the sliding mechanism and to be in conductive contact with the test target.

[0023] The above-mentioned short-circuit test device adopts a third cylinder to drive the first clamping plate and / or the second clamping plate, thereby realizing the adjustable distance between the first clamping plate and the second clamping plate. Due to the simple structure and low cost of the cylinder, the space of the short-circuit test device is also saved, and the manufacturing cost and maintenance cost of the short-circuit test device are reduced.

[0024] Optionally, the test target includes a battery.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0037] Please refer to Figure 1 , Figure 1 : is a three-dimensional diagram of the short-circuit test device 100 provided in the embodiment of the present application. The short-circuit test device 100 provided in the embodiment of the present application may include a static eliminator 110 and a test machine body 120; the test machine body 120 may include a frame 121 and a receiving mechanism 122; the receiving mechanism 122 may be arranged on the frame 121 and may be configured to receive a test target; the receiving mechanism 122 may have a static eliminator end; wherein the static eliminator end may be oriented in the same direction as a side of the received test target that is exposed to the outside of the receiving mechanism 122; the static eliminator 110 may be arranged on the frame 121 and may have an output end for outputting a static eliminator; the output end of the static eliminator 110 may be oriented toward the static eliminator end.

[0038] The static eliminator 110 can be an ion fan, an ultrasonic static eliminator, a photoelectric effect static eliminator, etc. The static eliminator can be the ion wind output by the ion fan, the ultrasonic wave output by the ultrasonic static eliminator, or the light output by the photoelectric effect static eliminator.

[0039] The structure of the test machine body 120 may be a structure known to those skilled in the art and capable of implementing a short-circuit test on a test target, or may be a structure described in subsequent embodiments of the present application.

[0040] Regarding the static-eliminating end on the receiving mechanism 122, illustratively, the receiving mechanism 122 has an opening facing upward, and the test target can enter the receiving mechanism 122 from the opening, and then be received by the receiving mechanism 122. Then, the side of the received test target facing upward is the side exposed to the outside of the receiving mechanism 122. If the test target is completely located in the receiving mechanism 122, then the side of the test target exposed to the outside of the test mechanism is usually also located in the receiving mechanism 122. If the test target is only partially located in the receiving mechanism 122, then the side of the test target exposed to the outside of the test mechanism is usually also located outside the receiving mechanism 122. Correspondingly, the static-eliminating end can be the edge of the opening of the receiving mechanism 122.

[0041] In the above implementation process, static electricity on the test target and in the air around the test target is eliminated by the static electricity eliminator 110, which avoids the influence of static electricity on the short circuit test to a certain extent, thereby improving the accuracy of the test.

[0042] Optionally, the short-circuit testing device 100 can also be equipped with a dust removal device and a pressure applying device. The static electricity on the test target and in the air around the test target can be eliminated by using a static eliminator, and a certain degree of pressure can be applied to the target object. At the same time, the device has a dust suction function, thereby avoiding the influence of static electricity, inadequate contact and dust on the short-circuit test to a certain extent, thereby improving the accuracy of the test.

[0043] Please combine Figure 1 Reference Figure 2 , Figure 2 yes Figure 1 A partial enlarged view of the short circuit test device 100 at A in the perspective view is shown. In some optional embodiments, the static eliminator 110 may include an ion blower; the output end of the static eliminator 110 may include an outlet 111 for outputting ion wind; the ion blower may be configured to output ion wind to the test target.

[0044] The ion blower can be an ion blower wand or other types of ion blowers.

[0045] In the above implementation process, by using an ion blower as the static electricity remover 110, compared with other types of static electricity removers 110, it is suitable for test targets of various materials, shapes and sizes, and can effectively neutralize static electricity regardless of whether the test target is transparent or conductive, and the ion blower has a relatively simple structure and low maintenance cost. Therefore, the applicability of the short-circuit test device 100 is improved, and the manufacturing and maintenance costs of the short-circuit test device 100 are reduced.

[0046] Please continue to refer to Figure 1 and Figure 2 In some optional embodiments, the air outlet 111 of the ion fan may have an air outlet 111 edge formed by surrounding; the air outlet 111 edge may include long edges 1111 opposite to each other; the extension direction of the long edge 1111 may be parallel to the plane of the side of the test target being received that is exposed outside the receiving mechanism 122.

[0047] Exemplarily, the air outlet 111 of the ion fan is rectangular, and the long edges 1111 opposite to each other on the edge of the air outlet 111 may be two long sides of the rectangle.

[0048] During the above implementation process, the long edges 1111 opposite to each other on the edge of the air outlet 111 are parallel to the plane of the surface of the test target exposed outside the receiving mechanism 122, so that the ion wind output by the ion blower can pass through the test target to the greatest extent, thereby improving the efficiency of static electricity removal.

[0049] Please continue to refer to Figure 1 In some optional embodiments, the test machine body 120 may also include a sliding mechanism 123 and a probe 124; the probe 124 may be slidably connected to the frame 121 through the sliding mechanism 123; the probe 124 may be configured to move toward the received test target through the sliding mechanism 123, and may be in conductive contact with the test target.

[0050] Taking a battery as an example, the probe 124 can be used to contact the positive electrode and the negative electrode of the battery respectively to perform a short circuit test on the battery.

[0051] The sliding mechanism 123 may include a pulley, a slider, etc., and a corresponding slide rail may be provided on the frame 121. The sliding of the sliding mechanism 123 on the frame 121 may be manual or automatic. Automatic sliding may be achieved by motor drive, cylinder drive, etc.

[0052] When the test starts, the sliding mechanism 123 can be controlled to move toward the test target so that the probe 124 contacts the test target; when the test is completed, the sliding mechanism 123 can be controlled to move away from the test target so that the probe 124 separates from the test target.

[0053] In the above implementation process, by configuring a sliding mechanism 123 for the probe 124 on the test machine body 120, the probe 124 is movable, which to a certain extent avoids the problems of the probe 124 obstructing the placement of the test target and the probe 124 being damaged by the test target when the test target is placed into the receiving mechanism 122.

[0054] Please continue to refer to Figure 1 In some optional embodiments, the testing machine body 120 may further include a first cylinder 125; the first cylinder 125 may be disposed on the frame 121; the power output end of the first cylinder 125 may be connected to the sliding mechanism 123 to drive the probe 124 to move closer to or away from the received test target.

[0055] In the above implementation process, the first cylinder 125 is used to drive the sliding mechanism 123, so that the probe 124 can automatically approach or move away from the test target. Since the cylinder has a simple structure and low cost, the space of the short-circuit test device 100 is saved, and the manufacturing cost and maintenance cost of the short-circuit test device 100 are reduced.

[0056] Please continue to refer to Figure 1 In some optional implementations, the testing machine body 120 may further include a lifting mechanism 126 ; one end of the lifting mechanism 126 may be connected to the frame 121 , and the other end of the lifting mechanism 126 may be connected to the receiving mechanism 122 .

[0057] The lifting mechanism 126 may be provided with pulleys, sliders, etc., and the frame 121 may be provided with corresponding guide rails, slideways, etc. The sliding of the lifting mechanism 126 on the frame 121 may be manual or automatic. Automatic lifting may be achieved by motor drive, cylinder drive, etc.

[0058] Taking batteries as an example, the positions of the positive and negative electrodes of batteries of different models are usually different. Therefore, the height of the receiving mechanism 122 is adjusted by the lifting mechanism 126 so that the probe 124 can smoothly contact the positive and negative electrodes of the battery.

[0059] In the above implementation process, the receiving structure on the test machine body 120 is provided with a lifting mechanism 126, so that the receiving mechanism 122 can be lifted and lowered, so that when the receiving mechanism 122 receives different test targets, the probe 124 can still smoothly contact the test target, and then smoothly perform the short circuit test, thereby improving the application range of the short circuit test device 100.

[0060] Please continue to refer to Figure 1 In some optional embodiments, the testing machine body 120 may further include a second cylinder 127; the second cylinder 127 may be disposed on the frame 121; the power output end of the second cylinder 127 may be connected to the lifting mechanism 126 to drive the lifting of the receiving mechanism 122.

[0061] In the above implementation process, the lifting mechanism 126 is driven by the second cylinder 127, so that the receiving mechanism 122 can be lifted and lowered. Due to the simple structure and low cost of the cylinder, the space of the short-circuit test device 100 is also saved, and the manufacturing cost and maintenance cost of the short-circuit test device 100 are reduced.

[0062] Please continue to refer to Figure 1 In some optional embodiments, the receiving mechanism 122 may include a guide rod 1221, a first clamping plate 1222 and a second clamping plate 1223; the guide rod 1221 may be arranged on the frame 121 along the horizontal direction; the first clamping plate 1222 may be arranged opposite to the second clamping plate 1223, and may be slidably mounted on the guide rod 1221 respectively; a clamping space for clamping a test target may be formed between the first clamping plate 1222 and the second clamping plate 1223.

[0063] The horizontal direction may be the horizontal direction, the vertical direction, or an inclined direction compared to the horizontal direction and the vertical direction. The first clamping plate 1222 and the second clamping plate 1223 may be provided with sleeve holes respectively to be sleeved on the guide rod 1221 .

[0064] Before the test object is placed in the receiving mechanism 122, the first clamping plate 1222 and the second clamping plate 1223 can slide on the guide rod 1221 to expand the distance between them. After the test object is placed in the receiving mechanism 122, the first clamping plate 1222 and the second clamping plate 1223 can slide on the guide rod 1221 to move closer to each other to clamp the test object.

[0065] In the embodiment of the present application, the receiving mechanism 122 may further include a third clamping plate, a fourth clamping plate, etc. The third clamping plate may form a clamping space with the second clamping plate 1223 , and the fourth clamping plate may form a clamping space with the third clamping plate.

[0066] In the above implementation process, the first clamping plate 1222 and the second clamping plate 1223 are slidably mounted on the guide rod 1221, so that the first clamping plate 1222 and the second clamping plate 1223 are movable, which facilitates the placement of the test object into the receiving mechanism 122. In addition, the distance between the first clamping plate 1222 and the second clamping plate 1223 is adjustable, so that the receiving mechanism 122 can receive test objects of different sizes, thereby improving the application range of the short circuit test device 100.

[0067] Please continue to refer to Figure 1 In some optional embodiments, the testing machine body 120 may further include a third cylinder 127; the third cylinder 127 may be disposed on the frame 121; the power output end of the third cylinder 127 may be connected to the first clamping plate 1222 and / or the second clamping plate 1223 to achieve relative proximity and relative distance between the first clamping plate 1222 and the second clamping plate 1223 through driving.

[0068] As an optional embodiment, on the basis that the first clamping plate 1222 is slidably sleeved on the guide rod 1221, a limiting member can be sleeved near the first clamping plate 1222 on the guide rod 1221 to limit the position of the first clamping plate 1222 on the guide rod 1221, thereby fixing the first clamping plate 1222. The power output end of the third cylinder 127 can be connected to the second clamping plate 1223, and the second clamping plate 1223 can be driven by the third cylinder 127 to move closer to or away from the first clamping plate 1222.

[0069] In the above implementation process, the third cylinder 127 is used to drive the first clamping plate 1222 and / or the second clamping plate 1223, so that the distance between the first clamping plate 1222 and the second clamping plate 1223 can be adjusted. Due to the simple structure and low cost of the cylinder, the space of the short-circuit test device 100 is also saved, and the manufacturing cost and maintenance cost of the short-circuit test device 100 are reduced.

By making the long edges 1111 relative to each other in the edge of the air outlet 111 of the ion fan parallel to the plane where the side exposed to the outside of the receiving mechanism 122 in the test target is located, the ion wind output by the ion fan can pass through the test target to the greatest extent, thereby improving the efficiency of removing static electricity.
