[0009] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0011] The present application discloses a battery detection device and a battery detection system. Figure 1 A schematic diagram of the structure of a battery detection device disclosed in an embodiment of the present application.

[0012] like Figure 1 As shown, the battery detection device disclosed in the present application includes a driving mechanism 110 and a magnetic field detection component 120 , wherein: the driving mechanism 110 is connected to the magnetic field detection component 120 , and the driving mechanism 110 drives the magnetic field detection component 120 to move on the surface of the battery 130 .

[0013] It should be noted that when the battery is charging and discharging, a magnetic field is generated, and the magnetic field data at different positions of the battery are different.

[0014] In the present application, the magnetic field detection element 120 can be fixedly connected to the driving mechanism 110. The magnetic field detection element 120 can detect the magnetic field data of the battery 130, and the driving mechanism 110 drives the magnetic field detection element 120 to move on the surface of the battery 130, so as to realize the detection of the battery magnetic field data.

[0015] An embodiment of the present application provides a battery detection device, which includes a driving mechanism 110 and a magnetic field detection component 120. The driving mechanism 110 is connected to the magnetic field detection component 120. The driving mechanism 110 drives the magnetic field detection component 120 to move on the surface of the battery 130, thereby realizing the detection of the battery magnetic field data.

[0016] In the embodiment of the present application, the battery detection device may further include an analysis instrument, which is electrically connected to the magnetic field detection element 120. That is, after the magnetic field detection element 120 is driven by the driving mechanism 110 to move on the surface of the battery 130 to detect the battery magnetic field data, the detected battery magnetic field data is sent to the analysis instrument, and the analysis instrument analyzes the battery magnetic field data.

[0017] It should be noted that the above-mentioned analysis instrument is an instrument capable of analyzing the magnetic field data of the battery. Exemplarily, the analyzing instrument may pre-store preset magnetic field data. When the analyzing instrument receives the battery magnetic field data sent by the magnetic field detection component 120, the analyzing instrument compares the preset magnetic field data with the battery magnetic field data. When the received battery magnetic field data is greater than the preset magnetic field data, the analyzing instrument determines that the battery magnetic field is abnormal, and displays a magnetic field abnormality prompt on the display interface. When the received battery magnetic field data is less than the preset magnetic field data, the battery magnetic field is determined to be normal, and the battery magnetic field is displayed as normal on the display interface. Alternatively, the analyzing instrument includes a first data interface and a second data interface, the first data interface is electrically connected to the magnetic field detection component 120, and the second data interface is electrically connected to a data sending device, and the data sending device is used to send set magnetic field data. When the analyzing instrument receives the battery magnetic field data sent by the magnetic field detection component 120 through the first data interface and receives the set magnetic field data sent by the data sending device through the second data interface, the analyzing instrument compares the set magnetic field data with the battery magnetic field data. When the battery magnetic field data is greater than the set magnetic field data, the analyzing instrument determines that the battery magnetic field is abnormal, and displays a magnetic field abnormality prompt on the display interface. When the battery magnetic field data is less than the set magnetic field data, the battery magnetic field is determined to be normal, and the battery magnetic field is displayed as normal on the display interface.

[0018] In one implementation, the magnetic field detection element 120 may include an inductor. That is, the magnetic field of the battery 130 can be sensed by the inductor, and the sensed magnetic field signal can be converted into a current signal and sent to the analysis instrument for analysis. Specifically, since the battery generates a magnetic field when it is charged and discharged, and the magnetic field data at different positions of the battery are different, when the driving mechanism 110 drives the inductor coil to move at the detection position of the battery 130, the magnetic flux passing through the inductor coil changes, thereby generating an induced current, which can characterize the magnetic field data at the detection position of the battery 130.

[0019] In addition, the magnetic field detection element 120 may also be a device or a combination device such as a magnetic field detection sensor that can achieve the above functions, and this application does not make any specific limitation on this.

[0020] In one implementation, the battery detection device may further include a signal interface 140, and the analysis instrument is electrically connected to the magnetic field detection element 120 via the signal interface 140. That is, the magnetic field detection element 120 sends the detected battery magnetic field data to the analysis instrument via the signal interface 140. Exemplarily, the signal interface 140 and the analysis instrument may be connected via a cable.

[0021] In the embodiments of the present application, Figure 2As shown, the battery detection device may further include a circuit board 150, the magnetic field detection component 120 and the signal interface 140 are arranged on the circuit board 150, and the circuit board 150 is connected to the driving mechanism 110. The circuit board 150 may include a pad corresponding to the magnetic field detection component 120 and a pad corresponding to the signal interface 140. In other words, the circuit board 150 provides a mounting base for the magnetic field detection component 120 and the signal interface 140, the magnetic field detection component 120 is fixed on the circuit board 150 through the corresponding pad, and the signal interface 140 is fixed on the circuit board 150 through the corresponding pad. Since the circuit board 150 is connected to the driving mechanism 110, the driving mechanism 110 drives the circuit board 150 to move the magnetic field detection component 120 arranged on the circuit board 150 on the surface of the battery 130.

[0022] In the embodiment of the present application, the magnetic field detection element 120 is disposed on the circuit board 150 near the battery 130 to facilitate the detection of the magnetic field data of the battery 130. Figure 1 As shown, when the circuit board 150 is perpendicular to the battery 130 and the tip of the circuit board 150 is close to the battery 130 , the magnetic field detector 120 can be set at the tip of the circuit board 150 and the signal interface 140 can be set in the middle of the circuit board 150 .

[0023] In one implementation, the magnetic field detection component 120 is spaced apart from the battery 130 by a preset distance to ensure that battery magnetic field data of appropriate strength can be detected. Exemplarily, the preset distance between the magnetic field detection component 120 and the battery 130 may be 0.5 mm. It should be noted that the preset distance between the magnetic field detection component 120 and the battery 130 may also be set according to actual needs.

[0024] In one implementation, the driving mechanism 110 may include a robot. By programming and controlling the robot, the robot drives the magnetic field detection element 120 to move on the surface of the battery 130 to detect the battery magnetic field data.

[0025] Exemplarily, the robot may include a signal receiving device, a processor, a driving member and a mechanical arm, wherein the signal receiving device is electrically connected to the processor, the processor is electrically connected to the driving member, the driving member is connected to the mechanical arm, and the magnetic field detection member 120 is connected to the mechanical arm. The signal receiving device is used to receive a control instruction sent by an external device for detecting the battery magnetic field data, and send the control instruction to the processor. The processor determines the target operation corresponding to the control instruction and the control signal corresponding to the target operation, and sends the control signal to the driving member. The driving member responds to the received control signal and drives the mechanical arm to move at a preset speed on the surface of the battery 130, thereby driving the magnetic field detection member 120 to move at a preset speed on the surface of the battery 130 to detect the battery magnetic field data. For example, the target operation may be to drive the mechanical arm to move at a preset speed within a predetermined area, and the predetermined area is an area corresponding to the battery surface, and the driving member may be a motor. It should be noted that the signal receiving device of the robot is wirelessly connected to the external device.

[0026] In addition, the driving mechanism 110 may also be a computer numerical control machine, factory automation equipment, or other device that can control the moving speed and record the coordinate position, and this application does not make any specific limitation on this.

[0027] The embodiment of the present application also discloses a battery detection system, which includes a conveying device and the battery detection device described above, wherein: the conveying device is used to convey the battery to a preset position, wherein the preset position is spaced a preset distance from the magnetic field detection element of the battery detection device. It should be noted that the conveying device can be pre-set with a battery placement area, and the preset distance here is the same as the preset distance described above, and illustratively, the preset distance can be 0.5 mm.

[0028] When it is necessary to detect the magnetic field data of the battery, the battery is first placed in the battery placement area of ​​the conveying device, the battery is conveyed to a preset position by the conveying device, and the battery is charged and discharged. Then, the driving mechanism 110 of the battery detection device drives the magnetic field detection element 120 to move on the surface of the battery 130 to realize the detection of the battery magnetic field data.

[0029] Exemplarily, the conveying device may be a linear conveying mechanism or a rotating conveying mechanism, which is not specifically limited in this application. In addition, the battery placement area of ​​the conveying device may also be provided with a power supply, and when the battery is placed in the battery placement area of ​​the conveying device, the battery is charged by the power supply to generate a magnetic field. Alternatively, the battery may also be charged by an external power supply, which is not specifically limited in this application.

[0030] An embodiment of the present application provides a battery detection system, which includes a conveying device and a battery detection device. When it is necessary to detect the magnetic field data of the battery, the battery is first conveyed by the conveying device to a preset position at a preset distance from the magnetic field detection element 120 of the battery detection device, and then the magnetic field detection element 120 is driven by the driving mechanism 110 of the battery detection device to move on the surface of the battery 130 to realize the detection of the battery magnetic field data.

[0031] In one implementation, the battery detection system may further include an electronic device and a controller, wherein the electronic device is electrically connected to the controller, and the controller is electrically connected to the conveying device and the driving mechanism 110, respectively. The electronic device sends a battery magnetic field data detection instruction to the controller, and the controller responds to the received battery magnetic field data detection instruction by sending a first control instruction to the conveying device. The conveying device responds to the received first control instruction to convey the battery to a preset position and sends a feedback signal to the controller. The controller responds to the received feedback signal to send a second control instruction to the driving mechanism 110. The driving mechanism 110 responds to the received second control instruction to drive the magnetic field detection element 120 to move on the surface of the battery 130 to detect the battery magnetic field data.

[0032] It should be noted that, when the driving mechanism 110 is a robot, the second control instruction sent by the controller to the driving mechanism 110 is the control instruction for detecting the battery magnetic field data sent by the external device and received by the signal receiving device of the robot mentioned above. When the signal receiving device of the robot receives the second control instruction, the second control instruction is sent to the processor of the robot. The processor of the robot determines the target operation corresponding to the second control instruction and the control signal corresponding to the target operation, and sends the control signal to the driving part of the robot. The driving part of the robot responds to the received control signal to drive the robot's mechanical arm to move at a preset speed on the surface of the battery 130, thereby driving the magnetic field detection part 120 to move at a preset speed on the surface of the battery 130 to realize the detection of the battery magnetic field data.
