[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application. In addition, it should be understood that the specific implementation methods described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, unless otherwise specified, the directional words used, such as "upper" and "lower", generally refer to the upper and lower parts of the device in actual use or working state, specifically the drawing direction in the accompanying drawings; and "inside" and "outside" refer to the outline of the device.

[0023] See Figure 1 , Figure 1 This is a connection diagram of a battery testing device provided in an exemplary embodiment of the present disclosure. This application provides a battery testing device, primarily used to detect whether an insulating film is correctly attached to a battery surface. Compared to visual inspection, this battery testing device is faster and more accurate, helping to improve detection efficiency and reduce the probability of false detection. Specifically, the battery testing device includes:

[0024] Power supply 1;

[0025] a first controller 2 , wherein a power interface of the first controller 2 is electrically connected to the power source 1 , and a detection cable of the first controller 2 is configured to contact a surface of a battery 4 to be detected;

[0026] The conductive detection component 3 has one end electrically connected to the power source 1 and the other end configured to contact the surface of the battery 4 to be detected.

[0027] It should be noted that Figure 1 The positional relationship of the various components shown in the figure, such as the power supply 1, the first controller 2 and the conductive detection component 3, is not the actual structural positional relationship. Figure 1 It mainly indicates the connection relationship between the components, not the actual spatial position relationship. Figure 1 The two batteries 4 shown in the figure are actually two tests of one battery 4, one is the test of the side surface of the battery 4, and the other is the test of the bottom surface of the battery 4. That is, the two batteries 4 shown in the figure are actually the connection relationship of the same battery 4 in two testing processes or two testing stations.

[0028] The technical solution provided by this application can achieve rapid detection of the insulation film attached to the surface of the battery 4, effectively preventing the insulation film from being missed and improving the problem of the visual inspection system taking a long time to detect the insulation film. In detail, by connecting the two ends of the first controller 2 to the power supply 1 and the surface of the battery 4 respectively, and connecting the two ends of the conductive detection component 3 to the power supply 1 and the surface of the battery 4 respectively, and taking advantage of the fact that the battery 4 surface is in an insulating state when the film is correctly attached, and in a conductive state when the film is not correctly attached, it can quickly and accurately determine whether the current insulation film is correctly attached to the surface of the battery 4. Specifically, when the insulating film is correctly affixed to the surface of the battery 4, the ends of the conductive detection component 3 and the first controller 2 that are respectively in contact with the surface of the battery 4 will not be connected through the battery 4, so that the power supply 1, the first controller 2 and the conductive detection component 3 will not form a loop, and the first controller 2 will not receive the missing affixation information; when the insulating film is not correctly affixed to the surface of the battery 4, the ends of the conductive detection component 3 and the first controller 2 that are respectively in contact with the surface of the battery 4 will be connected through the metal on the surface of the battery 4, so that the power supply 1, the first controller 2 and the conductive detection component 3 will form a loop, and the first controller 2 will receive the missing affixation information, completing the rapid detection of the insulating film attachment on the surface of the battery 4. Compared with visual inspection that requires repeated scanning of the same surface multiple times, the technical solution of the present application has faster detection and lower error detection rate.

[0029] It should be noted that, for the insulating film attached to the surface of the battery 4, there are generally only two situations: one is that the insulating film is completely attached to the surface of the battery 4, and the other is that it is not attached to the surface of the battery 4 at all, that is, the film-attaching equipment is missed or the film-attaching alignment fails, and the insulating film is not attached to the surface of the battery 4. Also, for the battery 4, in this embodiment, it is mainly aimed at the square lithium-ion battery 4. The shell of this battery 4 is made of metal aluminum, which has good conductive properties. The insulating film is attached to the aluminum shell for insulation. Of course, in other embodiments, the battery 4 can also be a battery 4 of other shapes or other materials. As long as the surface of the battery 4 needs to be attached with an insulating film, the present detection device can be applied.

[0030] Power supply 1 primarily provides a stable current or voltage signal to ensure reliable system operation. Connected via a cable to the power interface of first controller 2, power supply 1 provides the necessary power for PLC system operation. Furthermore, the current or voltage signal provided by power supply 1 is crucial for determining whether the current circuit is complete and whether the insulating film is properly attached.

[0031] First controller 2 is the device's detection and alarm unit, responsible for processing detection signals and generating alarms based on them. First controller 2 is connected to power supply 1 via its power interface to ensure the PLC's operational state. The input of first controller 2 is connected to conductive detection component 3 via a detection cable, receiving detection signals from conductive detection component 3. Based on this input signal, the controller determines whether battery 4 has a missing insulation film and takes appropriate action based on the result.

[0032] As for the conductive detection component 3, it is used to contact the surface of the battery 4 and transmit the detection signal. One end of it is connected to the power supply 1, and the other end is connected to the input end of the controller through a detection cable, forming a current loop. When the probe of the conductive detection component 3 contacts the surface of the battery 4 and detects the part of the battery 4 not covered by the insulating film, the conductive detection component 3 will transmit the electrical signal to the controller, and the controller will determine whether the battery 4 is missing based on the signal change. The conductive detection component 3 can flexibly adjust the specific position of its probe contact to adapt to batteries 4 of different sizes and shapes to ensure that the surface detection of the battery 4 can be fully covered.

[0033] The conductive detection component 3 directly contacts the surface of the battery 4 to form a stable detection circuit. When the detection probe contacts the surface of the battery 4 that is not covered with the insulating film, the circuit is connected, the PLC receives the signal, and can accurately determine whether there is a missing sticker phenomenon. Compared with the visual detection system, the conductive detection component 3 will not be disturbed by external light, environmental conditions, etc., and the detection results are more stable and accurate. The traditional visual detection system needs to scan the surface of the battery 4 multiple times, and the detection process is relatively time-consuming. The battery detection device of the present application uses direct contact of the probe to quickly feedback the detection signal in real time, which greatly shortens the detection time. The PLC system processes signals within milliseconds, and combined with the rapid rejection function of the automated production line, it can detect and process unqualified products in a very short time, significantly improving production efficiency. The conductive detection component 3 forms a physical detection method through direct contact with the surface of the battery 4, avoiding the common problems of missed detection and wrong detection in visual detection.

[0034] In some embodiments, the conductive detection component 3 includes a first driving mechanism 31 and a first conductive probe 32. The driving end of the first driving mechanism 31 is connected to the first conductive probe 32, and is used to drive one end of the first conductive probe 32 to contact the side of the battery 4, and the other end of the first conductive probe 32 is electrically connected to the power supply 1.

[0035] The first driving mechanism 31 is responsible for controlling the movement of the conductive probe to ensure that the conductive probe is in reliable contact with the side of the battery 4. The driving mechanism includes an electric or pneumatic driving source, and its driving output end is connected to the clamping arm 312. The clamping arm 312 is connected to the conductive probe and can realize the movement of the conductive probe through the action of the driving mechanism. When the detection device is working, the driving source is activated, and the clamping arm 312 drives the conductive probe to move toward the side of the battery 4, ensuring that one end of the probe is in direct contact with the side of the battery 4, and the other end is connected to the power supply 1 through the detection cable to form an electrical circuit. Through this design, the conductive probe can flexibly and stably contact multiple sides of the battery 4.

[0036] The first conductive probe 32 is designed from a highly sensitive conductive material, ensuring accurate detection of any missing adhesive on the battery 4 surface when in contact with the side of the battery 4. One end of the probe contacts the side of the battery 4 via a gripper arm 312, while the other end is connected to the controller and power supply 1 via a detection cable. When the probe contacts aluminum foil uncovered by the insulating film, current flows through the probe, forming a loop. This signal is transmitted to the controller, and the PLC determines whether any missing adhesive is present based on the changes in the loop.

[0037] Through the action of the drive mechanism, the probe can maintain stable contact pressure during the detection process to ensure the accuracy and consistency of the detection and avoid misjudgment due to poor contact. In actual operation, when the drive mechanism is activated, the first conductive probe 32 contacts different sides of the battery 4 in sequence, and the PLC system monitors the signal changes of the probe in real time. If the probe detects that the surface of the battery 4 is not covered by an insulating film or a blue film, the controller will immediately issue a command to mark the battery 4 as defective and initiate subsequent operations to remove the defective battery 4 from the production line.

[0038] It should be noted that the above embodiment uses a driving mechanism to realize automatic detection of the conductive probe, but the technical solution of the present application is not limited to automated detection. When automation is not possible, the staff can also use insulating gloves or other insulating handles to manually send the probe to the surface of the battery 4 to complete the detection of the battery 4.

[0039] Furthermore, the first driving mechanism 31 includes a first driving source 311 and a clamping arm 312 . The clamping arm 312 is connected to an output end of the first driving source 311 , and the first conductive probe 32 is connected to the clamping arm 312 .

[0040] The first driving source 311 can be an electric driving source, a pneumatic driving source, or a hydraulic driving source, and is selected according to the specific needs of the production line. The driving source drives the movement of the clamping arms 312 through its output terminal, which can provide sufficient driving force to enable the conductive probe to move to the side of the battery 4 and make stable contact with it. When the detection process begins, the first driving source 311 is activated, and the clamping arms 312 begin to move from the initial position, advancing toward the side of the battery 4. Under the push of the clamping arms 312, the conductive probe gradually approaches and makes contact with the side of the battery 4. The clamping arms 312 are the transmission components that connect the driving source and the conductive probes. Each clamping arm 312 is responsible for driving a conductive probe, and through a flexible mechanical design, it ensures that the probe can smoothly reach the surface of the battery 4 and apply appropriate contact pressure. The clamping arms 312 are connected to the output terminal of the driving source, so that the driving source can accurately control the movement path and contact force of the clamping arms 312, ensuring that the contact between the conductive probe and the surface of the battery 4 is stable and effective. The gripper arm 312 is constructed from a lightweight, high-strength metal or composite material that can withstand the force of the drive source while ensuring highly precise guidance and feedback. During testing, the gripper arm 312 adapts to the size and shape of the battery 4, ensuring the conductive probe can contact the sides of different battery types, enabling flexible testing.

[0041] Driven by the first driving source 311, the clamping arm 312 accurately moves the first conductive probe 32 to the side of the battery 4 for testing. The probe contacts the surface of the battery 4. If there is a conductive area on the surface of the battery 4 that is not covered by the insulating film, the conductive probe and the first controller 2 will form a path through the battery 4. The first controller 2 detects the current change, identifies it in real time, and responds. In addition, the first driving mechanism 31 uses a clamping arm 312, which can not only be used to drive the first conductive probe 32 to contact the surface of the battery 4, but also serve as a tool for clamping the battery 4. Specifically, when the first conductive probe 32 contacts the surface of the battery 4 and forms a loop, it means that the insulating film is not attached to the surface of the battery 4. The battery 4 will be judged as a defective product. The clamping arm 312 can then act as a clamping claw, clamping the defective battery 4 to the defective product output port, preventing the defective battery 4 from entering the market, and can also effectively replace a separate device for transporting the battery 4, saving costs.

[0042] In some embodiments, there are multiple clamping arms 312, one clamping arm 312 corresponding to one side of the battery 4, and each clamping arm 312 is connected to a first conductive probe 32. The number of clamping arms 312 can be selected based on the number of sides of the battery 4. For example, the battery 4 in this embodiment is a square battery 4 with four sides, a top surface, and a bottom surface. The clamping arms 312 and the first conductive probe 32 are mainly used to detect the four sides of the battery 4. In this case, there are four clamping arms 312, each corresponding to one side. When the clamping arms 312 are activated, the insulating film can be detected on all four sides simultaneously. It should be noted that the circuits formed by the first conductive probes 32 corresponding to each side are independent circuits to prevent interference between multiple conductive probes.

[0043] In some embodiments, the conductive detection assembly 3 includes a second drive mechanism 33 and a second conductive probe 34. The drive end of the second drive mechanism 33 is connected to the second conductive probe 34, and is used to drive one end of the second conductive probe 34 to contact the bottom surface of the battery 4. The other end of the second conductive probe 34 is electrically connected to the power supply 1. By utilizing the second drive mechanism 33 and the second conductive probe 34 to cooperate, the second conductive probe 34 is moved toward the bottom surface of the battery 4, so that the second conductive probe 34 can contact the bottom surface of the battery 4. If the insulating film is not properly attached to the bottom surface of the battery 4, the second conductive probe 34 will be connected to the first controller 2 to form a circuit. The first controller 2 detects the current change and issues an alarm. It should be noted that the circuits in which the second conductive probe 34 and the first conductive probe 32 are respectively independent circuits and do not affect each other. To achieve the goal of multiple first conductive probes 32 and second conductive probes 34 being independent circuits, the power supply 1 is provided with multiple power supply interfaces so that each conductive probe can be connected to an independent power supply interface.

[0044] Furthermore, the second drive mechanism 33 includes a second drive source 331 and a push plate 332. The push plate 332 is connected to the output terminal of the second drive source 331. One end of the second conductive probe 34 is fixed to the side of the push plate 332 facing away from the second drive source 331. Activating the second drive source 331 drives the push plate 332 toward the bottom surface of the battery 4, causing the second conductive probe 34 to contact the bottom surface of the battery 4, thereby detecting whether the bottom surface of the battery 4 is insulated. The second drive source 331 can be any of pneumatic, electric, or hydraulic drive sources, without limitation. In this embodiment, the second drive source 331 is specifically a drive cylinder.

[0045] It should be noted that the inspection of the side and bottom surfaces of the battery 4 can be performed simultaneously or in separate steps. If performed simultaneously, a bracket suitable for both bottom and side inspections is required. Specifically, the bracket is used to hold the battery 4, but the bottom surface of the battery 4 needs to be exposed for contact by the second conductive probe 34. Furthermore, the second conductive probe 34 and the driving cylinder need to be located below the bottom surface of the battery 4. Furthermore, a structure that exposes the side surface of the battery 4 is also required to allow the first conductive probe 32 to contact the side surface of the battery 4. This makes the bracket design more complex. Therefore, in this embodiment, the side and bottom surfaces of the battery 4 are inspected separately, first inspecting the side surface and then the bottom surface. Specifically, the first driving mechanism 31 drives the first conductive probe 32 toward the side surface of the battery 4 until the first conductive probe 32 contacts the side surface of the battery 4. If the first controller 2 issues an alarm, indicating that the insulating film is not attached to the side surface of the battery 4, the first driving mechanism 31 will be driven again to clamp the unqualified battery 4 and transport it to the unqualified product outlet, eliminating the need for further bottom inspection. If the first controller 2 does not sound an alarm, it indicates that the insulating film is correctly attached to the side of the battery 4. At this time, the first drive mechanism 31 will drive to clamp the battery 4 again until it is flipped flat, or directly clamp and flip the battery 4 so that the bottom surface of the battery 4 is parallel to the push plate 332. The second drive mechanism 33 is activated, and the second conductive probe 34 moves toward the bottom surface of the battery 4 until it contacts it. If the first controller 2 sounds an alarm, it indicates that the insulating film is not attached to the bottom surface of the battery 4. At this time, the first drive mechanism 31 will drive to clamp the unqualified battery 4 and transport it to the unqualified product output port. If the first controller 2 does not sound an alarm, it indicates that the insulating film is correctly attached to the bottom surface of the battery 4. At this time, the first drive mechanism 31 will transport the qualified battery 4 to the next process.

[0046] It should be noted that the control of the first drive mechanism 31 and the second drive mechanism 33 is mainly achieved through the second controller. The second controller is connected to the first controller 2. The first controller 2 transmits the signal to the second controller, and the second controller controls the first drive mechanism 31 and the second drive mechanism 33 according to the signal.

[0047] In any of the above embodiments, the circuits for the first conductive probe 32 and the second conductive probe 34 are independent of each other, and there are multiple first conductive probes 32, each of which has its own independent circuit. This ensures that multiple sides of the battery 4 can be independently tested, preventing interference between the multiple conductive probes and problems such as short circuits. Furthermore, the first conductive probe 32 and the second conductive probe 34 have the same structure.

[0048] And in any of the above embodiments, see Figure 2The first conductive probe 32 and the second conductive probe 34 are both spring probes. Specifically, the conductive probe includes a barrel 322, a spring (not shown), and a needle 321. When the needle 321 is compressed, it retracts into the barrel 322. The end of the needle 321 facing away from the barrel 322 is circular, with a diameter ranging from 7mm to 13mm. In this embodiment, the needle 321 has a diameter of 9mm. The circular configuration of the spring and needle 321 effectively prevents the probe from damaging the surface of the battery 4.

[0049] This application also provides a battery preparation system, including the battery coating device, battery testing device, and battery sorting device described in any of the aforementioned embodiments. The battery coating device is used to coat the battery with an insulating film. After coating, the battery is transported to the corresponding station of the battery testing device. The battery testing device performs a rapid test on the insulating film of the battery. After the test is completed, the battery sorting device sorts the battery according to the test results. This battery preparation system has all the beneficial effects of the aforementioned battery testing device, and this disclosure will not elaborate on them here.
