[0030] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the description.

[0031] In all the examples shown and discussed herein, any specific values should be construed as merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values.

[0032] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0033] According to an embodiment of the present application, an insulation detection device is provided. As Figures 1 to 5 shown, the insulation detection device of the present application includes a first fixing member 7, a detection main body 3, and an insulation detection generator 1. The first fixing member 7 is adapted to fix the workpiece to be detected 501. The detection main body 3 includes at least one conductive plate, and the detection main body 3 can move towards the first fixing member 7 so that the conductive plate is in electrical contact with the workpiece to be detected 501. The insulation detection generator 1 is electrically connected to the detection main body 3, and the insulation detection generator 1 is adapted to perform an insulation withstand voltage test on the workpiece to be detected 501.

[0034] In an example, the workpiece to be detected 501 is fixed to the first fixing member 7, and the detection main body 3 can move towards the first fixing member 7 so that the conductive plate is in electrical contact with the workpiece to be detected 501. The insulation detection generator 1 is electrically connected to the detection main body 3 and can perform an insulation withstand voltage test on the workpiece to be detected 501. By electrically contacting the conductive plate with the workpiece to be detected 501, the detection coverage can be improved, thereby improving the reliability of the insulation withstand voltage test. Moreover, the insulation detection device of the present application can automatically detect the insulation withstand voltage performance of the workpiece to be detected 501, thereby improving the detection efficiency and saving labor costs.

[0035] In this example, the insulation detection generator 1 is electrically connected to the conductive plate. After the conductive plate is in electrical contact with the workpiece to be detected 501, the insulation detection generator 1 is adapted to apply a voltage to the conductive plate, and the conductive plate and the workpiece to be detected 501 can form a loop with the positive and negative electrodes of the insulation detection generator 1, so as to perform an insulation withstand voltage test on the workpiece to be detected 501. Among them, the voltage applied by the insulation detection generator 1 can be set by those skilled in the art according to actual detection requirements and is not limited herein.

[0036] In this example, the detection main body 3 can move away from the first fixing member 7 to create space, so as to facilitate fixing the workpiece to be detected 501 to the first fixing member 7, and the position of the workpiece to be detected 501 corresponds to that of the detection main body 3. Then, the detection main body 3 can move towards the first fixing member 7, that is, towards the workpiece to be detected 501, so that the conductive plate can abut against the surface of the workpiece to be detected 501 to form an electrical contact.

[0037] In this example, the workpiece to be detected 501 can be a battery tray. By performing an insulation withstand voltage test on the battery tray, the insulation performance of the battery tray can be ensured, thereby improving the safety performance of the battery. Of course, the workpiece to be detected 501 can also be other types of workpieces, and the insulation withstand voltage test can be performed on them by the insulation detection device of the present application. Those skilled in the art can set according to the actual situation and are not limited herein.

[0038] In an example, as Figure 3 and Figure 4As shown, the at least one conductive plate includes a first conductive plate 305 and a plurality of second conductive plates 306. The plurality of second conductive plates 306 are arranged along the circumferential direction of the first conductive plate 305. The first conductive plate 305 is adapted to be in electrical contact with the bottom wall of the workpiece 501 to be detected, and the second conductive plate 306 is adapted to be in contact with the side wall of the workpiece 501 to be detected. By providing the first conductive plate 305 and the plurality of second conductive plates 306, the coverage area can be increased, which is beneficial to improving the reliability of detection.

[0039] As Figures 3 to 4 shown, in this example, the plurality of second conductive plates 306 are arranged along the circumferential direction of the first conductive plate 305. The first conductive plate 305 can be in electrical contact with the bottom wall of the workpiece 501 to be detected, and the second conductive plate 306 can be in contact with the side wall of the workpiece 501 to be detected. Thus, the comprehensiveness of detection can be improved.

[0040] For example, the first conductive plate 305 can be rectangular, and the second conductive plate 306 can also be rectangular. There are four second conductive plates 306, and the four second conductive plates 306 are respectively arranged at the four sides of the first conductive plate 305. The first conductive plate 305 is perpendicularly arranged with the second conductive plate 306. Of course, the first conductive plate 305 can also be pentagonal, and there are five second conductive plates 306. Those skilled in the art can set the structures and dimensions of the first conductive plate 305 and the second conductive plate 306 according to the specific structure of the battery tray, and no specific limitation is made here.

[0041] In an example, as Figure 3 shown, the plurality of second conductive plates 306 are movably connected to the first conductive plate 305. By movably connecting the second conductive plate 306 to the first conductive plate 305, the workpiece 501 to be detected with different sizes can be adapted.

[0042] In this example, the workpiece 501 to be detected has an inner cavity surrounded by a bottom wall and a side wall. The detection main body 3 can move into the inner cavity. The first conductive plate 305 is in electrical contact with the bottom wall of the inner cavity. Then, the plurality of second conductive plates 306 can move towards their corresponding side walls and abut against the side walls to form electrical contact. For different workpieces 501 to be detected, the sizes of their inner cavities are different. Thus, by movably arranging the second conductive plate 306, the workpiece 501 to be detected with different sizes can be adapted.

[0043] Wherein, regarding the moving stroke of the second conductive plate 306, those skilled in the art can determine it according to the actual situation, and no specific limitation is made here.

[0044] In an example, as Figure 3As shown, the insulation detection device further includes a first drive component 301, which is mounted on the first conductive plate 305, and an output end of the first drive component 301 is connected to the second conductive plate 306. The first drive component 301 can automatically drive the second conductive plate 306 to move.

[0045] like Figure 3 As shown, in this example, the first driving assembly 301 includes a first cylinder, which is fixedly mounted on the first conductive plate 305, and the output shaft of the first cylinder is fixedly connected to the second conductive plate 306. A plurality of first cylinders may be provided, and each second conductive plate 306 may be correspondingly connected to one or more first cylinders, thereby improving the stability of the second conductive plate 306 in moving and abutting against the side wall.

[0046] like Figure 3 As shown, in this example, a probe mounting block 302 is also connected to the output shaft of the first cylinder. The probe mounting block 302 is used to fix and install the probe, and the probe is electrically connected to the conductive plate and the insulation detection generator 1 respectively.

[0047] Of course, the first driving assembly 301 can also drive the second conductive plate 306 to move through other driving mechanisms, for example, the second conductive plate 306 can be driven to move by a motor in conjunction with a gear rack structure, or by a motor in conjunction with a lead screw 405 nut structure. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0048] In an example, Figure 1 , Figure 2 and Figure 5 As shown, the second driving assembly 404 is further included, and the second driving assembly 404 is connected to the first conductive plate 305 by transmission, and the second driving assembly 404 can drive the first conductive plate 305 to move along the first direction. The first conductive plate 305 is driven to move by the second driving assembly 404, that is, the detection body 3 is driven to move along the first direction, so that the detection body 3 is moved toward or away from the first fixing member 7, so that the detection body 3 can enter the inner cavity of the to-be-detected member 501, or move out of the inner cavity.

[0049] like Figure 1 As shown, in this example, the first direction may be a vertical direction, or in other words, a direction in which the detection body 3 is directed toward or away from the first fixing member 7. The second driving assembly 404 includes a second cylinder, and the first conductive plate 305 is driven to move along the first direction by the second cylinder.

[0050] like Figure 4As shown, in this example, the second drive assembly 404 further includes a connection plate 307, and the connection plate 307 can be fixedly connected to the first conductive plate 305 by fasteners such as screws or bolts. The connection plate 307 is provided with a mounting groove 309, and the output shaft of the second cylinder can be inserted into the mounting groove 309 and locked to the connection plate 307 by a locking block 308. The locking block 308 can also be a fastener such as a stud or a screw, or a structure such as a bayonet, as long as it can fix the output shaft to the connection plate 307, and is not specifically limited here.

[0051] Of course, the second driving assembly 404 can also drive the first conductive plate 305 to move through other driving mechanisms, for example, the first conductive plate 305 can be driven to move by a motor in conjunction with a gear rack structure, or by a motor in conjunction with a lead screw 405 nut structure. Those skilled in the art can determine according to actual conditions, and no specific limitation is made here.

[0052] In this example, the insulation detection generator 1 can perform a pre-test on the part to be detected 501 before performing an insulation withstand voltage test on the part to be detected 501. For example, the part to be detected 501 is a battery tray, and the tray is usually coated with an epoxy coating for insulation. If a tray that is not coated with an epoxy coating is tested, the tray has a strong conductivity, which can easily cause the tray to burn or break down and be damaged. Therefore, it is necessary to pre-test the tray first to ensure that the tray is coated with an epoxy coating. For example, the tray can be pre-tested by the first conductive plate 305, and the second drive assembly 404 drives the first conductive plate 305 to abut against the bottom wall of the tray. The insulation detection generator 1 is electrically connected to the first conductive plate 305. The insulation detection generator 1 can detect whether the tray is conductive by applying a small voltage, thereby being able to detect whether the tray is coated with an epoxy coating and avoiding a large voltage from breaking through the tray.

[0053] In an example, Figure 1 , Figure 2 and Figure 5 As shown, the insulation detection device further includes a third driving component 5, which is transmission-connected to the second driving component 404, and can drive the second driving component 404 to move along the second direction, thereby driving the first conductive plate 305 to move along the second direction. The third driving component 5 drives the first conductive plate 305 to move along the second direction, thereby driving the detection body 3 to move along the second direction, so that the detection body 3 can detect different positions of the component to be detected.

[0054] For example, the workpiece 501 to be detected has two inner cavities. The third driving component 5 can drive the detection main body 3 to move from one inner cavity to another inner cavity to improve the comprehensiveness of detection. Alternatively, the dimension of the workpiece 501 in the second direction is relatively large, and the stroke of the first driving component 301 is relatively small. Therefore, the third driving component 5 can move the detection main body 3 in the second direction, so as to detect multiple positions of the workpiece 501.

[0055] As Figure 5 shown, in this example, the third driving component 5 includes a lead screw 405. The lead screw 405 is screwed to the second driving component 404. The rotation of the lead screw 405 can drive the second driving component 404 to move in the second direction. One end of the lead screw 405 is connected to a driving motor 407, and the driving motor 407 drives the lead screw 405 to rotate.

[0056] The third driving component 5 further includes a first fixing seat 402. A guide rail 406 is arranged on the first fixing seat 402 in the second direction. The second driving component 404 includes a second air cylinder and a second fixing seat 403. The second air cylinder is fixedly installed on the second fixing seat 403. The second fixing seat 403 is slidably arranged on the guide rail 406. The lead screw 405 passes through the second fixing seat 403 and is screwed to the second fixing seat 403. The driving motor 407 is installed on the first fixing seat 402, and the rotating shaft of the driving motor 407 is connected to the lead screw 405. By driving the lead screw 405 to rotate, the second fixing seat 403 is driven to move along the guide rail 406.

[0057] Of course, the third driving component 5 can also drive the detection main body 3 to move through other types of driving mechanisms. For example, the detection main body 3 can also be driven to move by a motor cooperating with a gear-rack structure, or driven by an air cylinder. Those skilled in the art can determine according to the actual situation, and no specific limitation is made here.

[0058] As Figure 1 、 Figure 2 and Figure 5 shown, in this example, the insulation detection device further includes a second fixing member 2. The second fixing member 2 is located on the side opposite to the first fixing member 7. The second fixing member 2 and the first fixing member 7 are fixedly connected by a plurality of connecting columns 6. The first fixing seat 402 of the third driving component 5 is fixedly installed on the side of the second fixing member 2 facing the first fixing member 7.

[0059] In one example, as Figure 4 shown, the conductive plate includes conductive cotton 303 and a mounting plate 304. The conductive cotton 303 is arranged on one side of the mounting plate 304. The conductive cotton 303 is adapted to be in electrical contact with the workpiece 501 to be detected. The conductive cotton 303 can be in close fit with the workpiece 501 to be detected.

[0060] As shown Figure 4 in

[0060] , one side of the mounting plate 304 facing the component to be detected 501 is covered with conductive cotton 303. By contacting the component to be detected 501 through the conductive cotton 303, it is also possible to avoid scratching the component to be detected 501. Moreover, when a certain part of the component to be detected 501 leaks electricity, the conductive cotton 303 will be burned black or burned through, so that the leakage position of the component to be detected 501 can be clearly known. Among them, the conductive cotton 303 can be fixed on the mounting plate 304 by bonding means.

[0061] In this example, the structures of the first conductive plate 305 and the second conductive plate 306 are the same, and the second driving assembly 404 can be installed on the mounting plate 304 of the first conductive plate 305.

[0062] In one example, as shown Figure 1 and Figure 3 in Figure 1 , the insulation detection device further includes a plurality of limiting members 4. The plurality of limiting members 4 are connected to the first fixing member 7, and the plurality of limiting members 4 can be arranged along the circumferential direction of the component to be detected 501 to fix the component to be detected 501.

[0063] As shown Figure 1 and Figure 3 in Figure 1 , after the component to be detected 501 is placed on the first fixing member 7, the plurality of limiting members 4 are connected to the first fixing member 7, and the plurality of limiting members 4 are arranged along the circumferential direction of the component to be detected 501. By abutting the plurality of limiting members 4 against the outer side wall of the component to be detected 501, the component to be detected 501 can be fixed to avoid the component to be detected 501 from shifting during the insulation withstand voltage detection. For example, the plurality of limiting members 4 can be respectively arranged on three sides of the component to be detected 501.

[0064] In one example, as shown Figure 3 in Figure 3 , the first fixing member 7 is arranged in a matrix with a plurality of fixing grooves 701, and the limiting member 4 is detachably connected to the fixing groove 701.

[0065] The limiting member 4 is detachably installed in the fixing groove 701. When fixing the component to be detected 501, the position of the limiting member 4 can be installed according to the specific size of the component to be detected 501, so as to be able to adapt to components to be detected 501 of different sizes. Among them, the limiting member 4 can be a limiting block, and the limiting block can be detachably connected to the fixing groove 701 by means of clamping or the like.

[0066] As shown Figure 3 in Figure 3 , in one example, the insulation detection device further includes an induction device 502, and the induction device 502 can sense the position of the component to be detected 501. For example, when fixing the component to be detected 501, if the component to be detected 501 is tilted or not installed in the preset position, the induction device 502 lights up a red light. When the component to be detected 501 is fixed in place, the induction device 502 lights up a green light, so that the next operation can be carried out.

[0067] In this example, the sensing device 502 can also sense the position of the detection main body 3. For example, the sensing device 502 can sense whether the first conductive plate 305 of the detection main body 3 is in electrical contact with the bottom wall of the workpiece 501 to be detected.

[0068] In the above embodiments, the differences between the various embodiments are mainly described. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a more optimal embodiment. For the sake of brevity of the description, they will not be elaborated here.

[0069] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and not for limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention.
