[0058] The power source 1 is formed with a first conductive electrode and a second conductive electrode of different polarities, the conductive member 3 is electrically connected to the first conductive electrode, and the conductive member 3 is used to be electrically connected to at least part of the pins; the electrical connection member 2 is electrically connected to the second conductive electrode, and the number of the electrical connection members 2 is multiple, and corresponds to a plurality of busbars 231 to be detected one by one, and the electrical connection member 2 is used to be electrically connected to the corresponding busbar 231; it should be noted that: in actual detection, only the welding conditions of some of the busbars 231 and the nickel sheet 232 need to be detected in this process, while the busbars 231 and the nickel sheet 232 of other groups can be detected in other processes, so it is summarized here that the conductive member 3 is used to be electrically connected to at least part of the pins, and the electrical connection member 2 is used to be electrically connected to at least part of the busbar 231. Of course, it is not limited to this, and the conductive member 3 can also be electrically connected to all the pins, and all the electrical connection members 2 are electrically connected to all the corresponding busbars 231, which can be selected according to actual needs;

[0059] An indicator light 4 is provided on the circuit where the conductive member 3 is connected to the first conductive electrode and / or on the circuit where the electrical connection member 2 is connected to the second conductive electrode. That is to say, the indicator light 4 can be provided only on the circuit where the electrical connection member 2 is connected to the second conductive electrode, or the indicator light 4 can be provided only on the circuit where the conductive member 3 is connected to the first conductive electrode, or the indicator light 4 can be provided on both the circuit where the conductive member 3 is connected to the first conductive electrode and the circuit where the electrical connection member 2 is connected to the second conductive electrode. Preferably, in this embodiment, the indicator light 4 is provided only on the circuit where the electrical connection member 2 is connected to the second conductive electrode. Of course, it is not limited thereto, and the above three forms can be freely selected according to actual needs.

[0060] According to the structure described above, when the detection unit provided by the present application is used to detect the conduction status of the nickel sheet 232 and the bus bar 231 after welding, multiple parallel detection paths can be formed, each of which passes through the corresponding power supply 1, the indicator light, that is, Figure 1 The structure of the lamp 4, bus 231, nickel sheet 232, circuit board 233, pins of wiring harness terminal 234 and conductive member 3, when each detection path is electrically connected, if the corresponding indicator light is Figure 1 If the light 4 in the figure is on, it means that this detection path is connected, then it can be judged that there is no problem after the nickel sheet 232 and the bus 231 on this detection path are welded. Figure 1 If the light 4 in the detection path is not on, it means that this detection path is in a disconnected state, so it can be determined that there is a problem after the nickel sheet 232 and the bus bar 231 on this detection path are welded.

[0061] It can be seen that the present application provides a device for assisting in detecting whether there are problems at the welding point between the nickel sheet 232 and the bus bar 231 on the pole ear bracket 23. Instead of using multiple probes to test the multiple pins of the wiring harness terminal 234 one by one as in the past, the multiple pins of the wiring harness terminal 234 are integrated and connected in parallel through the conductive component 3. Especially in a small space, it is easier to operate than the existing structure, greatly reduces the operating difficulty, greatly improves the detection efficiency, reduces the labor intensity of workers, and is less likely to have misjudgment problems.

[0063] According to the structure described above, the conductive component 3 is generally made of metal, which is relatively hard, so as to avoid damaging the pins of the wiring harness terminal 234 when it contacts the pins. Furthermore, a flexible conductive protective layer 5 is provided on the side of the conductive component 3 close to the pins to protect the pins and avoid damage to the pins. Moreover, the flexible conductive protective layer 5 ensures that the conductive component 3 can fully contact multiple pins during testing, thereby ensuring the stability of the equipment.

[0064] Further, preferably, the flexible conductive shielding layer 5 is fixed to a side of the conductive component 3 close to the pins. It should be noted that the flexible conductive shielding layer 5 may also be provided on the pins of the wiring harness terminal 234 and the like.

[0065] Further, preferably, the flexible conductive protection layer 5 can be fixed on the conductive component 3 by melting, gluing or bolts, etc., but of course, it is not limited thereto.

[0066] Further, preferably, the material of the flexible conductive protective layer 5 can be conductive cotton. Of course, it is not limited thereto, and the material of the flexible conductive protective layer 5 can also be selected according to actual needs.

[0069] The detection device includes a first support member 6, a pressing drive device 7, a second support member 8, a third support member 9, an electrical connection member 2, a lateral drive device 11, a transfer member 12 and a conductive member 3;

[0070] The pressing driving device 7 is arranged on the first supporting member 6, and the second supporting member 8 is connected to the driving end of the pressing driving device 7; the third supporting member 9 is connected to the second supporting member 8, and the electrical connection member 2 is arranged on the third supporting member 9, and the pressing driving device 7 can drive the electrical connection member 2 to move along the first preset direction a, so that the electrical connection member 2 can contact with the bus 231 or the nickel sheet 232;

[0071] The transverse driving device 11 is arranged on the second supporting member 8, and the transfer member 12 is connected to the driving end of the transverse driving device 11; the conductive member 3 is arranged on the transfer member 12, and the transverse driving device 11 can drive the conductive member 3 to move along the second preset direction b, so that the conductive member 3 can contact the pin of the wiring harness terminal 234; one of the conductive member 3 and the electrical connection member 2 is used to connect the positive pole of the power supply 1, and the other is used to connect the negative pole of the power supply 1, and at least one of the two connected circuits is provided with a detection light 4.

[0072] According to the structure described above, the use process of the detection device provided in the present application is as follows: first, the tray 24 with the pole ear bracket 23 is placed or transported to the bottom of the conductive component 3 and the electrical connection component 2, and then the downward driving device 7 is used to drive the electrical connection component 2 to descend along a first preset direction, such as a vertical direction, until the electrical connection component 2 contacts the bus 231, and then the transverse driving device 11 is used to drive the conductive component 3 to move transversely in a second preset direction b, such as a horizontal direction, until the conductive component 3 contacts the pin of the wiring harness terminal 234, thereby forming a detection circuit, and then the power supply 1 can be turned on for detection. If the indicator light is not on, it means that this line is not connected, then it means that there is a problem with the welding of the nickel sheet 232 corresponding to this line and the bus 231. If the indicator light is on, it means that this line is not connected, then it means that there is no problem with the welding of the nickel sheet 232 corresponding to this line and the bus 231.

[0073] It can be seen that the present application provides a device for assisting in detecting whether there are problems at the welding point between the nickel sheet 232 and the bus bar 231 on the pole ear bracket 23. Instead of using multiple probes to test the multiple pins of the wiring harness terminal 234 one by one as in the past, the multiple pins of the wiring harness terminal 234 are integrated and connected in parallel through the conductive component 3. This is easier to operate than the existing structure, especially in a small space. It greatly reduces the operating difficulty, greatly improves the detection efficiency, reduces the labor intensity of workers, and is less likely to cause misjudgment. It has high detection accuracy and a longer service life, does not need to be replaced frequently, and helps to reduce production costs.

[0076] In this embodiment, preferably, Figure 4 , Figure 6 and Figure 7 As shown, the detection device also includes a lifting drive device 14 and a bearing member 15; wherein, along the first preset direction a, the bearing member 15 is arranged below the conductive member 3 and the electrical connection member 2, and the bearing member 15 is used to place a tray 24 loaded with the pole ear bracket 23; the driving end of the lifting drive device 14 is connected to the bearing member 15, and the lifting drive device 14 is used to drive the bearing member 15 together with the tray 24 to move along the first preset direction a.

[0077] According to the structure described above, when the logistics line 25 passes through the detection device, the lifting drive device 14 can drive the bearing member 15 to drive the pallet 24 thereon to rise and fall synchronously. In particular, when the lifting drive device 14 drives the bearing member 15 to rise, the bearing member 15 can be separated from the logistics line 25, that is, the pallet 24 can be stopped at this station. When the detection of the pole ear bracket 23 is completed, the lifting drive device 14 is used to drive the bearing member 15 to descend and fall back to the logistics line 25, and continue to be transported forward to move to the next work. Further, preferably, the logistics line 25 includes two conveying rails 251 arranged in sequence along the second preset direction b, and it should be noted that the conveying direction of the pallet 24 along the logistics line 25 is the same as the third preset direction c.

[0078] Further, preferably, the lifting drive device 14 is a cylinder, but is not limited thereto, and may also be a combination of a motor and a transmission structure such as a gear and a rack.

[0079] It should be noted that: this device is not limited to being used in conjunction with the logistics line 25, that is to say, this device can also be used without the logistics line 25. In this case, there is no need to separate the tray 24 from the logistics line 25 and keep it on this work, and thus there is no need to equip the jacking drive device 14 and the load-bearing component 15. The ear bracket 23 to be inspected can be directly placed manually on this work station, that is, on the workbench below the conductive component 3 and the electrical connection component 2.
