Testing equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on October 31, 2023, with application number 202311428734.5 and invention name “Detection Equipment”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of battery detection, and in particular to a detection device. Background Art

[0003] Battery cells are an important component of power batteries. If there are defects on the surface of battery cells, it will seriously affect the performance of the power battery. The appearance inspection of battery cells before unloading is the last checkpoint of battery cell safety inspection and is related to the safety of battery cells. Therefore, the appearance inspection of battery cells is very important.

[0004] At present, in the automated inspection equipment mainly used for battery cell inspection, the sensors, cameras and other devices used for inspection are mostly concentrated, which leads to the fact that the efficiency of the inspection equipment often depends on the inspection cycle of each inspection device, while various material moving components such as loading components and unloading components are prone to idleness, resulting in the inability to fully utilize the cycle of the material moving components; there are also solutions to repeatedly set up multiple identical inspection devices to improve the efficiency of the material moving components, but this type of equipment has a complex structure, a high function duplication rate, a high failure rate and a high cost.

[0005] Summary of the Invention

[0006] In view of the above problems, the present application provides a detection device that can simplify the mechanical structure of the detection device and improve the efficiency of battery cell detection.

[0007] The present application provides a testing device for testing battery cells. The testing device includes:

[0008] The first detection module and the second detection module are respectively used to detect different parts of the battery cell;

[0009] A loading module, used to obtain and transfer battery cells, and the loading module can drive the battery cells through the first detection module;

[0010] a carrier assembly for receiving the battery monomer transferred from the loading module, and the carrier assembly for conveying the battery monomer through the second inspection module;

[0011] The unloading module is used to obtain and transfer battery cells transported by the carrier assembly.

[0012] In the technical solution of this embodiment, the various detection devices in the detection equipment are respectively set as the first detection module and the second detection module, and the loading module is able to pass through the first detection module during the process of transferring the battery cells, and the first detection module is able to detect the battery cells passing through during the process, thereby reducing the time required for battery cell detection on the carrier assembly, optimizing the structural layout, and improving detection efficiency.

[0013] In some embodiments, the detection equipment further includes a first discharge port and a second discharge port, and the unloading module is further used to transfer the battery cells to the first discharge port or the second discharge port.

[0014] In the technical solution of this embodiment, the unloading module can transfer the battery cells to the first discharge port and the second discharge port respectively, so that the detection equipment can output qualified battery cells and unqualified battery cells respectively, thereby increasing the degree of automation of the detection equipment and improving the detection efficiency of the detection equipment.

[0015] In some embodiments, the material unloading module includes a material unloading and transferring component, a material unloading conveying component, and a material unloading and sorting component;

[0016] The unloading and transferring assembly is used to obtain battery cells from the carrier assembly and transfer the battery cells to the unloading and conveying assembly;

[0017] The unloading and conveying assembly is used to allow the battery cells transferred from the unloading and transferring assembly to pass through the unloading and sorting assembly and be conveyed to the second discharge port;

[0018] The unloading and sorting component is used to obtain battery cells from the unloading and conveying component and move the battery cells to the first discharge port.

[0019] The technical solution of this embodiment provides some structures in the unloading module, wherein the unloading transfer component is used to transfer the battery monomers to the unloading conveying component, and the unloading conveying component is used to finally convey the battery monomers to the second discharge port, and the unloading sorting component can obtain qualified battery monomers in the process, so that the battery monomers at the second discharge port are all unqualified products, so that the unloading module has the ability to sort qualified battery monomers and unqualified battery monomers, and at the same time, the unloading conveying component can also play a transfer role for the battery monomers, thereby improving the smoothness of the operation of the unloading module, so as to better design the operation rhythm of the detection equipment.

[0020] In some embodiments, the unloading conveyor assembly includes at least two unloading conveyor belts, which are used to receive battery monomers transferred from the unloading assembly and to convey the battery monomers to the second discharge port.

[0021] The technical solution of this embodiment provides some structures of the unloading conveying assembly, and further improves efficiency by arranging multiple unloading conveying belts to simultaneously convey battery cells.

[0022] In some embodiments, at least two unloading conveyor belts are arranged in sequence along the first direction, and unloading positions are provided on the unloading conveyor belts, and the unloading positions on different unloading conveyor belts are arranged in sequence along the second direction;

[0023] The first direction is perpendicular to the second direction, and the second direction is parallel to the extending direction of the unloading conveyor belt.

[0024] Because when the unloading and transferring assembly transfers battery cells onto the unloading conveyor, the transferred battery cells may pass over other battery cells on the unloading conveyor. If the transferred battery cells fall at this time, collisions between the battery cells will occur, which may lead to safety accidents such as fire and explosion. Accordingly, the technical solution of this embodiment sets unloading positions on the unloading conveyor, and staggers the unloading positions on different unloading conveyor belts. This ensures that when the unloading and transferring assembly transfers battery cells onto the unloading conveyor, other battery cells are unlikely to appear under the transferred battery cells, thereby reducing the occurrence of safety accidents caused by falling battery cells and improving the safety performance of the detection equipment.

[0025] In some embodiments, the unloading and transferring assembly includes a variable-distance unloading jaw, which is used to transfer the battery cells from the carrier assembly to different unloading positions.

[0026] Because different unloading positions are staggered, that is, the distances between each unloading position and the carrier assembly are different, the technical solution of this embodiment can simultaneously obtain battery cells from the carrier assembly through the variable-distance unloading clamp, and simultaneously transfer each battery cell to a different unloading position, so that the battery cells can remain synchronized during the transfer process, so as to facilitate the design of the production rhythm of this step, and also facilitate the coordination of the action of the unloading conveyor belt to improve the safety performance of the detection equipment.

[0027] In some embodiments, the unloading module further includes a buffer assembly, the unloading and sorting assembly can transfer the battery cells to the buffer assembly, and the unloading and sorting assembly can transfer the battery cells from the buffer assembly to the unloading conveying assembly.

[0028] Because the unloading and conveying assembly is used to convey battery cells to the unloading and sorting assembly and to convey unqualified battery cells to the second discharge port, and the unloading and sorting assembly is used to transfer qualified battery cells to the first discharge port, the number of battery cells obtained by the unloading and sorting assembly during each transfer of qualified battery cells may be different, resulting in the number of qualified battery cells output by the detection equipment each time may be different, and affecting the subsequent operation of other equipment. Accordingly, in order to ensure that the unloading and sorting assembly transfers the same number of battery cells to the first discharge port each time, the technical solution of this embodiment provides a cache assembly, and the sorting assembly can transfer the insufficient number of battery cells to the cache assembly for pre-storage, or the sorting assembly can obtain pre-stored qualified battery cells from the cache assembly to make up the number, so that the unloading and sorting assembly ultimately transfers the same number of battery cells to the first discharge port.

[0029] In some embodiments, the cache component includes a cache location for accommodating a battery cell;

[0030] The number of cache locations is one less than the number of unloading conveyor belts, or the number of cache locations is greater than or equal to the number of unloading conveyor belts.

[0031] In the technical solution of this embodiment, a plurality of cache bits are provided on the cache component, so that the cache component can adapt to various situations corresponding to different numbers of qualified battery cells.

[0032] In some embodiments, the blanking and sorting assembly includes a sorting bracket and a sorting clamp;

[0033] The sorting jaws are movably arranged on the sorting bracket, and can transfer battery cells from the unloading conveyor belt to the buffer assembly or the first discharge port. The sorting jaws can transfer battery cells from the buffer assembly to the unloading conveyor belt.

[0034] The technical solution of this embodiment provides some structures of the unloading and sorting components, so that each battery cell can be individually grasped by multiple independent sorting jaws, so as to obtain qualified battery cells in the unloading and conveying components without avoiding unqualified battery cells, thereby achieving the sorting effect; at the same time, the independent sorting jaws can also obtain battery cells from the cache position according to the number of qualified battery cells, so that the number of battery cells transferred to the first discharge port by the unloading and sorting components can be kept consistent.

[0035] In some embodiments, the number of the sorting jaws is the same as the number of the unloading conveyor belts, and the sorting jaws are arranged opposite to the corresponding unloading conveyor belts.

[0036] The technical solution of this embodiment further limits the number of sorting jaws and makes the sorting jaws correspond one-to-one with the unloading conveyor belt, so that each sorting jaw can independently obtain qualified battery cells, thereby achieving the sorting effect.

[0037] In some embodiments, the unloading and sorting assembly further includes a sorting blocking member, which is movably disposed on the sorting bracket and can block the unloading conveying assembly from conveying the battery cells to the second discharge port.

[0038] Because the unloading conveying assembly can eventually convey the battery cells to the second discharge port, and the unloading sorting assembly can obtain qualified battery cells during this process, so that the battery cells at the second discharge port are all unqualified products. Accordingly, the technical solution of this embodiment provides a sorting blocker. When the unloading conveying assembly conveys the battery cells to the second discharge port, the sorting blocker blocks the qualified battery cells so that the sorting claws can obtain the corresponding qualified battery cells, and the unloading conveying assembly can convey the unqualified battery cells to the second discharge port, so as to achieve the effect of sorting qualified battery cells from unqualified battery cells.

[0039] In some embodiments, the number of the sorting blocking members is the same as the number of the unloading conveyor belts, and the sorting blocking members correspond one-to-one to the corresponding unloading conveyor belts.

[0040] The technical solution of this embodiment makes the sorting blocking member correspond one-to-one with the unloading conveyor belt, so that the sorting blocking member blocks the qualified battery cells conveyed on the unloading conveyor belt, thereby assisting the unloading conveyor belt and the sorting clamp to achieve the sorting effect.

[0041] In some embodiments, the loading module includes a loading and transferring component, a loading and conveying component, and a loading and transferring component. The loading and transferring component is used to obtain battery cells and transfer the battery cells to the loading and conveying component. The loading and conveying component is used to obtain battery cells from the loading and transferring component and pass the battery cells through the first detection module. The loading and transferring component is used to obtain battery cells from the loading and conveying component and transfer the battery cells to the carrier component.

[0042] The technical solution of this embodiment provides some structures of the loading module, which obtains battery cells through the loading and transferring assembly and transfers the battery cells to the loading and conveying assembly. It also drives the battery cells through the first detection module through the loading and conveying assembly, so that the first detection module can detect the passing battery cells. In the process of the loading and conveying assembly conveying the battery cells, the loading and transferring assembly can repeat the action of obtaining the battery cells again to improve the detection efficiency and facilitate better design of the operating rhythm of the detection equipment.

[0043] In some embodiments, the loading module further includes a transfer assembly;

[0044] The loading and transferring assembly includes two loading and transferring clamps, one of which is used to obtain a battery cell and transfer the battery cell to the transfer assembly, and the other of which is used to obtain a battery cell from the transfer assembly and transfer the battery cell to the loading and conveying assembly.

[0045] The technical solution of this embodiment further provides some structures of the loading module, and the loading and transferring assembly includes two loading and transferring clamps, one of which can transfer the battery cell to the transfer assembly, and the other can transfer the battery cell from the transfer assembly to the loading and conveying assembly. The two loading and transferring clamps can act simultaneously to further improve the detection efficiency, reduce the action interval time, and facilitate better design of the operation rhythm of the detection equipment.

[0046] In some embodiments, the loading module further includes a loading and transporting assembly and a column separation assembly, wherein the loading and transporting assembly is used to obtain battery cells from the loading and transporting assembly and transfer the battery cells to the column separation assembly;

[0047] The column assembly is used to accommodate battery cells, and the loading and transporting assembly can obtain battery cells from the column assembly.

[0048] The technical solution of this embodiment further provides some structures of the loading module, which transfers the battery cells on the loading and conveying assembly through the loading and conveying assembly, and receives and temporarily stores the battery cells from the loading and conveying assembly through the column assembly, so as to shorten the action cycle of the loading and conveying assembly, thereby facilitating a good design of the operating rhythm of the testing equipment.

[0049] In some embodiments, the column assembly includes at least two loading positions, and the at least two loading positions are arranged sequentially along the third direction;

[0050] The column separation component further includes at least two column separation belts, which are arranged in sequence along the fourth direction, and the column separation belts correspond to the loading positions one by one;

[0051] The third direction is the extending direction of the column strips, and the fourth direction is perpendicular to the third direction.

[0052] During the process of transferring battery cells from the loading and transporting assembly to the carrier assembly, the transferred battery cells may pass over other battery cells on the sub-assembly assembly. If the transferred battery cells fall at this time, collisions between the battery cells may occur, potentially leading to safety accidents such as fire and explosion. Accordingly, the technical solution of this embodiment sets loading positions on the sub-assembly assembly and staggers the different loading positions. This ensures that during the process of transferring battery cells from the loading and transporting assembly to the carrier assembly, other battery cells are less likely to appear under the transferred battery cells, thereby reducing the occurrence of safety accidents caused by falling battery cells and improving the safety performance of the detection equipment.

[0053] In some embodiments, the loading and transfer assembly includes a loading and transfer jaw with a variable distance, which is used to transfer battery cells in different loading positions to different carrier assemblies.

[0054] Because different loading positions are staggered, that is, the distances between each loading position and the carrier assembly are different, the technical solution of this embodiment can simultaneously obtain battery cells from the array assembly through the loading variable-distance clamp, and simultaneously move each battery cell to different positions of the carrier assembly, so that the battery cells can remain synchronized during the transfer process, so as to facilitate the design of the production rhythm of this step, and also facilitate the coordination of the movement of the array assembly to improve the safety performance of the detection equipment.

[0055] In some embodiments, the detection device further includes a standard verification module, which is used to convey the standard battery to the loading module, and the standard verification module is also used to receive the standard battery conveyed from the unloading module.

[0056] In order to make the detection equipment have higher detection accuracy, it is necessary to calibrate the detection equipment frequently. Accordingly, the technical solution of this embodiment provides a standard calibration module, which can transport standard batteries to the loading module. The standard batteries with qualified parameters can be transported to the loading module. After the standard batteries are transported to the loading module, they can go through the actions of the carrier module and the unloading module in turn and finally return to the standard calibration module. During this process, the first detection module and the second detection module can detect the standard batteries. The staff can determine whether there is any abnormality in the detection equipment based on the monitoring results to achieve the effect of calibration of the detection equipment.

[0057] In some embodiments, the standard calibration module includes at least two calibration conveyor belts, each calibration conveyor belt is used to transport a standard battery.

[0058] The technical solution of this embodiment enables the standard calibration module to include multiple calibration conveyor belts to correspond to the transfer component and the unloading conveyor component, so that the calibration conveyor belt can transport the standard battery to the transfer component, and the unloading conveyor component can also transport the standard battery back to the calibration conveyor belt.

[0059] In some embodiments, the carrier assembly includes at least two carriers, and the carriers are used to carry battery cells and drive the battery cells to pass through the second detection module.

[0060] The technical solution of this embodiment provides some structures of the carrier assembly, so that the carrier assembly includes at least two carriers, so that the carrier assembly can simultaneously transport multiple battery cells and the second detection module can detect multiple battery cells to improve detection efficiency.

[0061] In some embodiments, the first detection module includes a bottom surface detection component, and the bottom surface detection component is used to detect the bottom surface of the battery cell; and / or

[0062] The first detection module includes a first side detection component, which is used to detect two opposite side surfaces of the battery cell.

[0063] The technical solution of this embodiment provides some structures of the first detection module, so that the first detection module can detect the bottom surface and two opposite side surfaces of a passing battery cell.

[0064] In some embodiments, the second detection module includes a top surface detection component, and the top surface detection component is used to detect the top surface of the battery cell; and / or

[0065] The second detection module includes a pole detection component, which is used to detect the pole of the battery cell; and / or

[0066] The second detection module includes an explosion-proof valve detection component, which is used to detect the explosion-proof valve of the battery cell; and / or

[0067] The second detection module includes a second side detection component, which includes at least one detection device. The second side detection component is used to detect two opposite side surfaces of the battery cell.

[0068] The technical solution of this embodiment provides some structures of the second detection module, so that the second detection module can detect the pole, explosion-proof valve, top surface and other two opposite side surfaces of the passing battery cell.

[0069] In some embodiments, the unloading module is further used to obtain the battery cells and transfer the battery cells to the carrier assembly;

[0070] The carrier assembly is also used to receive the battery monomers transferred from the unloading module and transport the battery monomers through the second inspection module;

[0071] The loading module is further used to obtain battery cells from the carrier assembly and drive the battery cells through the first inspection module.

[0072] In the technical solution of this embodiment, the detection equipment can also move in the reverse direction. For example, when the detection equipment detects a large number of unqualified battery cells, the detection equipment can move in the reverse direction, allowing the battery cells to enter the detection equipment from the unloading module to re-inspect the battery cells, thereby further confirming whether the battery cells are qualified.

[0073] In some embodiments, the detection equipment also includes a first feeding module with one end extending to the unloading module. The first feeding module is used to transport battery cells. The loading module can obtain battery cells from the first feeding module, and the unloading module can transfer the battery cells to the first feeding module.

[0074] In the technical solution of this embodiment, a first feeding module is provided, so that the first feeding module conveys the battery monomers outputted at the end of the previous process to the detection equipment for acquisition by the loading module; at the same time, because the first feeding module extends to the first discharge port, the first feeding module can also convey the battery monomers transferred by the unloading module to the next process, so as to realize continuous detection of the battery monomers.

[0075] In some embodiments, the detection equipment further includes a second feeding module disposed at the unloading module, and the unloading module is capable of transferring the battery cells to the second feeding module.

[0076] In the technical solution of this embodiment, a second feeding module is provided, so that the second feeding module can transport the battery cells at the second discharge port to other locations, so that the unloading module can continue to transport unqualified battery cells to the second discharge port without causing congestion, jamming, etc. at the second discharge port.

In the description of the embodiments of this application, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0110] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent the following three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0114] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0115] Battery cells are a crucial component of power batteries. Surface defects can severely impact battery performance. Depressions or cracks on the outer shell of a battery cell can lead to leakage and instability, significantly reducing its stability and potentially posing a fire hazard. Surface defects also include abnormalities in the appearance of the terminal and explosion-proof valve, which can negatively impact the stability and safety of the battery cell.

[0116] In order to improve the safety performance of battery cells, the appearance inspection of battery cells before unloading is an important checkpoint in the battery cell safety inspection and is related to the safety issues of battery cells.

[0117] Currently, in the automated testing equipment primarily used for battery cell appearance inspection, the sensors, cameras, and other devices used for inspection are mostly centralized. This results in the efficiency of the inspection equipment often depending on the inspection cycle of each inspection device. Various material handling components, such as loading and unloading components, are prone to being idle, resulting in the material handling component cycles not being fully utilized. In other words, during a single inspection cycle of this type of equipment, the efficiency of the material handling components does not match that of the inspection equipment, resulting in low efficiency of the material handling components, and even possible idle waiting periods. This makes it difficult to set the inspection time of the inspection equipment, making it difficult to speed up the inspection time of the inspection equipment, and thus low inspection efficiency.

[0118] Currently, there are also solutions that duplicate the same detection device to improve the efficiency of the material moving component. In this type of equipment, the same detection device is usually repeated in multiple groups to match the detection cycle of the detection device with the material moving component's material moving cycle, thereby speeding up the detection equipment's detection cycle and making it easier for staff to set the cycle according to needs. However, this type of equipment is usually complex in structure and has a high rate of functional duplication. The increase in detection devices also leads to increased failure rates and increased costs.

[0119] Based on the above considerations, in order to solve the problem that the current detection equipment cannot take into account simple structure, low functional repetition and high efficiency at the same time, the embodiment of the present application provides a detection device, which divides the detection module into two parts, a first detection module and a second detection module, and sets the first detection module at the loading module, so that the first detection module can detect the battery cell during the process of transferring the battery cell by the loading module, thereby reducing the time required for battery cell detection on the carrier assembly, optimizing the structural layout, and improving the detection efficiency.

[0120] The inspection device 100 disclosed in the embodiments of this application is used to perform appearance inspection on battery cells 200. Battery cells 200 can be cylindrical, flat, rectangular, or in other shapes. That is, the battery cells 200 to be inspected can be prismatic, cylindrical, or other types of battery cells. Battery cells 200 can be secondary or primary batteries; they can also be lithium-sulfur, sodium-ion, or magnesium-ion batteries, but are not limited thereto.

[0121] For the convenience of description, the following embodiments are described by taking a battery cell 200 of an embodiment of the present application as a square-shell battery cell.

[0122] Please refer to Figure 1, which is a schematic diagram of the exploded structure of a battery cell 200 provided in some embodiments of the present application. A battery cell 200 is the smallest unit that makes up a battery. As shown in Figure 1, a battery cell 200 includes an end cap 201, a housing 202, a cell assembly 203, and other functional components.

[0123] The end cap 201 refers to a component that covers the opening of the shell 202 to isolate the internal environment of the battery cell 200 from the external environment. Without limitation, the shape of the end cap 201 can be adapted to the shape of the shell 202 to match the shell 202. Optionally, the end cap 201 can be made of a material with a certain hardness and strength (such as aluminum alloy), so that the end cap 201 is not easily deformed when squeezed or collided, so that the battery cell 200 can have a higher structural strength and improved safety performance.

The cell assembly 203 is mainly formed by winding or stacking positive and negative electrode sheets, and a separator is usually provided between the positive and negative electrode sheets. The parts of the positive and negative electrode sheets with active substances constitute the main body of the cell assembly 203, and the parts of the positive and negative electrode sheets without active substances each constitute a tab.

During the charge and discharge process of the battery, the positive active substance and the negative active substance react with the electrolyte, and the tabs connect the poles 2011 to form a current loop.

[0141] According to some embodiments of the present application, referring to Figures 2 and 3, Figure 2 is a schematic diagram of the detection equipment 100 according to some embodiments of the present application, and Figure 3 is a schematic diagram of the loading module 40, the unloading module 60 and related mechanisms in the detection equipment 100 according to some embodiments of the present application.

[0142] In some embodiments of the present application, the detection equipment 100 also includes a first discharge port and a second discharge port, and the unloading module 60 is also used to transfer the battery cells 200 to the first discharge port or the second discharge port, that is, the unloading module 60 also has a sorting function at this time, for example, the unloading module 60 can transfer qualified battery cells 200 to the first discharge port, and can transfer unqualified battery cells 200 to the second discharge port.

[0146] According to some embodiments of the present application, referring to Figures 3, 4, 5, and 6, Figure 3 is a schematic diagram of the loading module 40, the unloading module 60 and related mechanisms in the detection equipment 100 according to some embodiments of the present application, Figure 4 is a stereoscopic schematic diagram of the unloading and sorting component 63 in the unloading module 60 according to some embodiments of the present application, Figure 5 is a stereoscopic schematic diagram of the unloading conveying component 62 and the unloading and sorting blocking member 633 according to some embodiments of the present application, and Figure 6 is a stereoscopic schematic diagram of the sorting claw 632 in the unloading and sorting component 63 according to some embodiments of the present application.

[0147] In some embodiments of the present application, the unloading module 60 includes an unloading and transferring component 61, an unloading conveying component 62 and an unloading and sorting component 63; wherein, the unloading and transferring component 61 is used to obtain the battery cell 200 from the carrier component 50 and transfer the battery cell 200 to the unloading and conveying component 62; the unloading and conveying component 62 is used to allow the battery cell 200 transferred from the unloading and transferring component 61 to pass through the unloading and sorting component 63 and be conveyed to the second discharge port; the unloading and sorting component 63 is used to obtain the battery cell 200 from the unloading conveying component 62 and transfer the battery cell 200 to the first discharge port.

[0148] The unloading and transferring component 61 refers to a structure or a combination of structures that can obtain and transfer battery cells 200. The unloading and transferring component 61 can include a manipulator, a clamp, a trolley, a conveyor belt or other structures; the battery cells 200 obtained by the unloading and transferring component 61 come from the carrier component 50, that is, the unloading and transferring component 61 can obtain battery cells 200 from the carrier component 50; the unloading and transferring component 61 can also transfer the obtained battery cells 200 to the unloading and conveying component 62.

[0149] The unloading and conveying component 62 refers to a structure or a combination of structures that obtain batteries and convey battery cells 200. The unloading and conveying component 62 may include a conveyor belt, a trolley or other structures; the battery cells 200 obtained by the unloading and conveying component 62 come from the unloading and transferring component 61; in the process of the unloading and conveying component 62 conveying the battery cells 200, the battery cells 200 can pass through the unloading and sorting component 63 and finally be conveyed to the second discharge port.

[0150] The unloading and sorting component 63 refers to a structure or structural combination that can obtain and transfer battery cells 200. The unloading and sorting component 63 may include a manipulator, a clamp, a trolley, a conveyor belt or other structures; the battery cells 200 obtained by the unloading and sorting component 63 come from the unloading and conveying component 62, that is, in the process of the unloading and conveying component 62 conveying the battery cells 200 to the second discharge port, the unloading and sorting component 63 can obtain the battery cells 200 from the unloading and conveying component 62; the unloading and sorting component 63 can also transfer the obtained battery cells 200 to the first discharge port.

[0151] In some embodiments, during the process of the unloading conveying component 62 conveying the battery cells 200 to the second discharge port, the unloading and sorting component 63 can obtain qualified battery cells 200 from the unloading conveying component 62 and transfer the qualified battery cells 200 to the first discharge port, while the battery cells 200 conveyed to the second discharge port by the unloading conveying component 62 are all unqualified products.

[0152] The unloading module 60 achieves the technical effect of sorting battery cells 200 by setting up the unloading conveying component 62 and the unloading sorting component 63; at the same time, by adjusting the conveying distance, conveying speed and other parameters of the unloading conveying component 62, the unloading conveying component 62 can play the role of transfer and temporary storage of battery cells 200.

[0153] The three components of the unloading and transferring component 61, the unloading conveying component 62 and the unloading and sorting component 63 decompose the unloading and sorting process. Specifically, the unloading and transferring component 61 is used to transfer the battery cell 200 from the carrier component 50 to the unloading conveying component 62, the unloading conveying component 62 is used to convey the battery cell 200 to the second discharge port, and the unloading and sorting component 63 is used to transfer the battery cell 200 from the unloading conveying component 62 to the first discharge port. Compared with the unloading process achieved through a complex structure, this setting makes the action of each component relatively simple, and the three components can move synchronously, so that the detection equipment 100 has a faster detection rhythm, improves the detection efficiency, and is also convenient for setting different detection rhythms according to needs.

[0154] This embodiment provides some structures in the unloading module 60, wherein the unloading transfer component 61 is used to transfer the battery cell 200 to the unloading conveying component 62, and the unloading conveying component 62 is used to finally convey the battery cell 200 to the second discharge port, and the unloading sorting component 63 can obtain qualified battery cells 200 in the process, so that the battery cells 200 at the second discharge port are all unqualified products, so that the unloading module 60 has the ability to sort qualified battery cells 200 and unqualified battery cells 200, and at the same time, the unloading conveying component 62 can also play a transfer role for the battery cells 200, thereby improving the smoothness of the operation of the unloading module 60, so as to better design the operation rhythm of the detection equipment 100.

[0155] In some embodiments of the present application, the unloading conveying assembly 62 includes at least two unloading conveying belts 621 . The unloading conveying belts 621 receive the battery cells 200 transferred from the unloading assembly and are used to convey the battery cells 200 to the second discharge port.

[0156] The unloading conveyor belt 621 refers to a conveyor belt structure capable of carrying and conveying the battery cells 200 . The unloading conveyor belt 621 may include a polyvinyl chloride (PVC) conveyor belt, a belt conveyor belt, a chain plate conveyor belt, or other conveyor belts.

[0157] Because during the production process of battery cells 200, battery cells 200 usually flow between different production equipment in the form of multiple groups, the number of unloading conveyor belts 621 is at least two, so that the detection equipment 100 can output multiple battery cells 200 at a time to meet production needs, and it is also convenient to improve the conveying efficiency of the unloading conveying component 62.

[0158] Parameters such as the conveying distance and conveying speed of the unloading conveyor belt 621 are affected by the transfer frequency of the unloading and transferring component 61, so that when the unloading and transferring component 61 transfers the battery cell 200 to the unloading conveyor belt 621, the transferred battery cell 200 will not collide with other battery cells 200, thereby reducing the collision damage that may occur during the detection of the battery cell 200, and can also reduce the occurrence of safety accidents such as fire and explosion caused by collisions between battery cells 200; parameters such as the conveying distance and conveying speed of the unloading conveyor belt 621 are also affected by the transfer frequency of the unloading and sorting component 63, so that the unloading and sorting component 63 can obtain the battery cell 200 from the unloading conveyor belt 621 every time, thereby reducing the occurrence of idleness of the unloading and sorting component 63, so as to improve the detection efficiency and equipment utilization.

[0159] In some embodiments, the number of unloading conveyor belts 621 can be consistent with the number of battery cells 200 that the unloading and transferring assembly 61 can transfer at a single time; in other embodiments, the number of unloading conveyor belts 621 can also be more than the number of battery cells 200 that the unloading and transferring assembly 61 can transfer at a single time.

[0160] In some embodiments, the maximum number of battery cells 200 that can be transferred by the unloading and sorting assembly 63 at a time may be consistent with the number of unloading conveyor belts 621 .

[0161] This embodiment provides some structures of the unloading conveyor assembly 62 , and further improves efficiency by disposing multiple unloading conveyor belts 621 to simultaneously convey battery cells 200 .

[0162] In some embodiments of the present application, at least two unloading conveyor belts 621 are arranged in sequence along the first direction, and a unloading position 622 is provided on the unloading conveyor belt 621. The unloading positions 622 on different unloading conveyor belts 621 are arranged in sequence along the second direction; the first direction is perpendicular to the second direction, and the second direction is parallel to the extension direction of the unloading conveyor belt 621.

[0163] The unloading position 622 refers to the position on the unloading conveyor belt 621 for placing the battery cell 200. In the process of the unloading transfer component 61 transferring the battery cell 200 to the unloading conveyor belt 621, the unloading transfer component 61 can transfer the battery cell 200 to the unloading position 622 of the unloading conveyor belt 621; the unloading position 622 does not move with the movement of the unloading conveyor belt 621, that is, when the battery cell 200 is transferred to the unloading position 622 of the unloading conveyor belt 621, the movement of the unloading conveyor belt 621 will cause the battery cell 200 to leave the corresponding unloading position 622 and make the unloading position 622 vacant, so that another battery cell 200 can be transferred to the unloading position 622.

[0164] In some embodiments, the unloading position 622 may simply refer to a position set in space; in other embodiments, a component that can limit the position of the battery cell 200 may be set above the unloading conveyor belt 621 to form the unloading position 622. At this time, the battery cell 200 should be able to move with the movement of the unloading conveyor belt 621 and leave the unloading position 622.

[0165] 3 , the first direction is the direction of the X axis in the figure, and the second direction is the direction of the Y axis in the figure.

[0166] The unloading conveyor belts 621 are arranged sequentially along the first direction, which means that at least two unloading conveyor belts 621 are arranged side by side along the first direction; the second direction is parallel to the extension direction of the unloading conveyor belts 621, which means that the unloading conveyor belts 621 can drive the battery cells 200 to move along the second direction.

[0167] Because there are at least two unloading conveyor belts 621, and each unloading conveyor belt 621 is provided with a unloading position 622, that is, the unloading positions 622 are arranged sequentially in the first direction, and at the same time, the unloading positions 622 are also arranged sequentially along the second direction, that is, at least two unloading positions 622 are arranged obliquely and staggered, and each unloading position 622 does not overlap in the first direction and the second direction.

[0168] In some embodiments, referring to Figure 3, the unloading conveying assembly 62 includes four unloading conveyor belts 621. Along the direction from near to far from the carrier assembly 50, the four unloading conveyor belts 621 are successively referred to as the first conveyor belt, the second conveyor belt, the third conveyor belt and the fourth conveyor belt. Correspondingly, the unloading positions 622 on the four unloading conveyor belts 621 are respectively referred to as the first unloading position, the second unloading position, the third unloading position and the fourth unloading position. The four unloading conveyor belts 621 all convey battery cells 200 along the direction from left to right; at this time, the first unloading position 622 is to the right of the second unloading position 622, the second unloading position 622 is to the right of the third unloading position 622, and the third unloading position 622 is to the right of the fourth unloading position 622. As the four unloading conveyor belts 621 move, there are always no battery cells 200 between the four unloading positions 622 and the carrier assembly 50.

[0169] Since the collision of battery cells 200 may cause damage to the battery cells 200, and the collision between battery cells 200 may also cause safety accidents such as fire and explosion, the unloading and transferring component 61 should reduce the occurrence of crossing battery cells 200 during the process of transferring battery cells 200, so as to reduce the occurrence of battery cells 200 falling and causing collision of battery cells 200 during the process of crossing battery cells 200.

[0170] During the process of the unloading and transferring assembly 61 transferring the battery cells 200, the situation of crossing the battery cells 200 means that the transferred battery cells 200 will pass over other battery cells 200 on the unloading conveyor belt 621 from above; in this process, if the transferred battery cells 200 fall, collisions between the battery cells 200 may occur.

[0171] Accordingly, this embodiment sets a unloading position 622 on the unloading conveyor belt 621, and the unloading positions 622 on different unloading conveyor belts 621 are staggered, so that when the unloading and transferring component 61 transfers the battery cell 200 to the unloading conveyor belt 621, it is not easy for other battery cells 200 to appear under the transferred battery cell 200, thereby reducing the occurrence of safety accidents caused by the falling of the battery cell 200 and improving the safety performance of the detection equipment 100.

[0172] In some embodiments of the present application, the unloading and transferring assembly 61 includes a variable-distance unloading jaw 611 , which is used to transfer the battery cells 200 from the carrier assembly 50 to different unloading positions 622 .

[0173] The variable-distance unloading clamp 611 refers to a structure or a combination of structures that can shift different battery cells 200 to different distances. During the process of the unloading and transferring component 61 transferring a battery cell 200 at a single time, the distance between each unloading position 622 and the carrier component 50 is different. Accordingly, the variable-distance unloading clamp 611 can shift different battery cells 200 to different distances.

[0174] In some embodiments, the variable-length unloading jaws 611 may include multiple jaws with different strokes, each jaw being used to obtain a battery cell 200. During a single transfer process of the unloading and transferring component 61, multiple jaws act simultaneously but with different strokes, so that multiple jaws can simultaneously obtain the battery cell 200 and can simultaneously transfer the battery cell 200 to different unloading positions 622; in other embodiments, the variable-length unloading jaws 611 may also include multiple jaws with the same stroke. In this case, the time for each jaw to open and put down the battery cell 200 is different, that is, multiple jaws simultaneously obtain the battery cell 200 and act synchronously with the same stroke, but multiple jaws open in sequence and transfer the battery cell 200 to the corresponding unloading position 622; in some other embodiments, the variable-length unloading jaws 611 may also transfer the battery cell 200 to different unloading positions 622 through other structures.

[0175] In some embodiments, the number of jaws in the variable-length unloading jaw 611 is the same as the number of the unloading conveyor belt 621, so that during a single transfer process of the variable-length unloading jaw 611, each jaw can transfer a battery cell 200 to the corresponding unloading conveyor belt 621.

[0176] Because different unloading positions 622 are arranged in an staggered manner, that is, the distance between each unloading position 622 and the carrier assembly 50 is different, this embodiment obtains the battery cells 200 from the carrier assembly 50 at the same time through the unloading variable-distance clamp 611, and simultaneously transfers each battery cell 200 to a different unloading position 622, so that the battery cells 200 can be kept synchronized during the transfer process, so as to facilitate the design of the production rhythm of this step, and also facilitate the coordination of the action of the unloading conveyor belt 621 to improve the safety performance of the detection equipment 100.

[0177] In some embodiments, the unloading and transferring assembly 61 includes a unloading and transferring bracket, and the unloading and variable-distance clamp 611 also includes a variable-distance base movably provided on the unloading and transferring bracket. For example, the variable-distance base can be raised and lowered to remove the battery cell 200 from the carrier assembly 50, or to place the battery cell 200 into the unloading position 622; the variable-distance base can be driven by a cylinder, a hydraulic cylinder or other devices.

[0178] A plurality of clamping jaws are provided on the variable pitch base, and each clamping jaw is controlled by a different feeding device to achieve different strokes for different clamping jaws. The feeding device can be a cylinder, a hydraulic cylinder or other devices.

[0179] In some embodiments of the present application, the unloading module 60 further includes a cache component 64 , the unloading and sorting component 63 can transfer the battery cells 200 to the cache component 64 , and the unloading and sorting component 63 can transfer the battery cells 200 from the cache component 64 to the unloading conveying component 62 .

[0180] The cache component 64 refers to a structure or a combination of structures used to temporarily store battery cells 200; the cache component 64 may include a storage table, a placement bin or other structures; the battery cells 200 stored in the cache component 64 come from the unloading and sorting component 63; the cache component 64 may be located on one side of the unloading conveyor belt 621, or may be located at other locations. In order to reduce the time for a single transfer of the unloading and sorting component 63, the distance between the cache component 64 and the unloading conveyor belt 621 and the first discharge port should be relatively small.

[0181] Since the unloading and conveying component 62 is used to convey the battery cells 200 to the unloading and sorting component 63, and to convey the unqualified battery cells 200 to the second discharge port, and the unloading and sorting component 63 is used to transfer the qualified battery cells 200 to the first discharge port, the unloading and sorting component 63 may obtain different numbers of battery cells 200 each time it transfers qualified battery cells 200, which may result in the number of qualified battery cells 200 output by the detection equipment 100 each time being different, and affect the subsequent operation of other equipment.

[0182] Accordingly, in order to ensure that the number of battery cells 200 transferred to the first discharge port by the unloading and sorting component 63 is the same each time, this embodiment provides a cache component 64. The sorting component can first transfer the insufficient number of battery cells 200 to the cache component 64 for pre-storage, or the sorting component can obtain pre-stored qualified battery cells 200 from the cache component 64 to make up the quantity, so that the number of battery cells 200 finally transferred to the first discharge port by the unloading and sorting component 63 is the same.

[0183] In some embodiments, the buffer assembly 64 includes a plurality of buffer locations for accommodating the battery cells 200 .

[0184] A cache location refers to a position on the cache assembly 64 that is used to accommodate a battery cell 200. The cache location can be a fixed position in space, or a physical structure can be provided on the cache assembly to define the specific location of the cache location. In some embodiments, the cache assembly 64 includes a storage platform with a plurality of ribs protruding from the storage platform. The plurality of ribs form a cache location, so that the battery cell 200 can be placed in the cache location surrounded by the plurality of ribs.

[0185] Because the maximum number of battery cells 200 that the unloading and sorting assembly 63 can obtain at a single time is the same as the number of unloading conveyor belts 621, the number of battery cells 200 outputted from the first discharge port each time is the same as the number of unloading conveyor belts 621. In some embodiments, the number of buffer locations can be one less than the number of unloading conveyor belts 621, so that the number of battery cells 200 transferred to the first discharge port by the unloading and sorting assembly 63 each time remains consistent. Specifically, the unloading and sorting assembly 63 can either transfer battery cells 200 from the unloading conveyor assembly 62 to the buffer location 64, or transfer battery cells 200 from the buffer location 64 to the unloading conveyor assembly 62, so that the number of battery cells 200 on the unloading conveyor assembly 62 is the same as the number of battery cells 200 to be outputted from the first discharge port. At this point, the unloading and sorting assembly 63 can then transfer the battery cells 200 from the unloading conveyor assembly 62 to the first discharge port. In other embodiments, the number of buffer locations can also be greater than or equal to the number of unloading conveyor belts 621.

[0186] In some embodiments, there are four unloading conveyor belts 621, and the number of battery cells 200 outputted from the first discharge port each time is also four. At this time, there are three cache positions on the cache component 64; when there are four qualified battery cells 200 on the unloading conveyor component 62, the unloading sorting component 63 can directly transfer the four battery cells 200 to the first discharge port; when there are three qualified battery cells 200 on the unloading conveyor component 62 and there are no battery cells 200 on the cache component 64, the unloading sorting component 63 can transfer the three battery cells 200 to the cache component 64; when there are three qualified battery cells 200 on the unloading conveyor component 62 When there are two qualified battery cells 200 on the unloading conveying component 62 and there are battery cells 200 on the cache component 64, the unloading and sorting component 63 can transfer a battery cell 200 on the cache component 64 to the unloading conveying component 62. At this time, there are four qualified battery cells 200 on the unloading conveying component 62, and the unloading and sorting component 63 can transfer the four battery cells 200 to the first discharge port; when there are two qualified battery cells 200 on the unloading conveying component 62 and there are no battery cells 200 on the cache component 64, the unloading and sorting component 63 can transfer the two qualified battery cells 200 to the cache component 64; When there are two qualified battery cells 200 and one battery cell 200 on the cache component 64, the unloading and sorting component 63 can transfer the two battery cells 200 to the cache component 64; when there are two qualified battery cells 200 on the unloading conveying component 62 and two or three battery cells 200 on the cache component 64, the unloading and sorting component 63 can transfer the two battery cells 200 on the cache component 64 to the unloading conveying component 62. At this time, there are four qualified battery cells 200 on the unloading conveying component 62, and the unloading and sorting component 63 can transfer the four battery cells 200 to the first discharge port; when unloading When there is a qualified battery cell 200 on the conveying component 62 and there is at least one vacant cache position on the cache component 64, the unloading and sorting component 63 can transfer the battery cell 200 to the cache component 64; when there is a qualified battery cell 200 on the unloading conveying component 62 and there are three battery cells 200 on the cache component 64, the unloading and sorting component 63 can transfer the three battery cells 200 on the cache component 64 to the unloading conveying component 62. At this time, there are four qualified battery cells 200 on the unloading conveying component 62, and the unloading and sorting component 63 can transfer the four battery cells 200 to the first discharge port.

[0187] It is understandable that since the number of battery cells 200 that need to be output at a time from the first discharge port is limited, the situations that the unloading and sorting component 63 needs to handle are also limited. Therefore, the control module of the control detection equipment 100 can control the unloading and sorting component 63 to perform corresponding various actions according to different situations.

[0188] In this embodiment, a plurality of cache bits are provided on the cache component 64 so that the cache component 64 can adapt to various situations corresponding to different numbers of qualified battery cells 200 .

[0189] In some embodiments of the present application, the unloading and sorting component 63 includes a sorting bracket 631 and a sorting clamp 632; the sorting bracket 631 is arranged on the frame 10; the sorting clamp 632 is movably arranged on the sorting bracket 631, and the sorting clamp 632 can transfer the battery cell 200 from the unloading conveyor belt 621 to the cache component 64 or the first discharge port, and the sorting clamp 632 can transfer the battery cell 200 from the cache component 64 to the unloading conveyor belt 621.

[0190] The sorting bracket 631 refers to a structure or a combination of structures used to provide a fixed foundation for the sorting jaws 632; the sorting bracket 631 can be a frame structure, or a plate-shaped, block-shaped or other shaped structure; the sorting bracket 631 is arranged on the frame 10 and is used to provide a fixed foundation for the sorting jaws 632.

[0191] The sorting jaw 632 refers to a structure or a combination of structures that can obtain and put down the battery cell 200; the sorting jaw 632 can include a manipulator, or it can include a clamp or other structure that can obtain the battery cell 200; the sorting jaw 632 can transfer the battery cell 200 from the unloading conveyor belt 621 to the cache assembly 64, and the sorting jaw 632 can also transfer the battery cell 200 from the cache assembly 64 to the unloading conveyor belt 621. The sorting jaw 632 can also transfer the battery cell 200 from the unloading conveyor belt 621 to the first discharge port. Accordingly, the sorting jaw 632 can move along the sorting bracket 631 to drive the battery cell 200 to move between the unloading conveyor belt 621, the cache assembly 64 and the first discharge port, and the sorting jaw 632 can also be raised and lowered to place the battery cell 200 or drive the battery cell 200 to rise for easy transfer.

[0192] The number of the sorting jaws 632 and the unloading conveyor belt 621 can be the same or different.

[0193] Each sorting jaw 632 can only obtain one battery cell 200 at a time and drive it to move. Multiple sorting jaws 632 can move synchronously or independently to flexibly transfer the battery cell 200 to the unloading conveyor belt 621, the cache component 64 or the first discharge port.

[0194] In some embodiments, the unloading and sorting component 63 also includes a sorting base 634, which can move along the sorting bracket 631, and the movement of the sorting base 634 can be achieved by a rodless cylinder, a screw slider structure or other structures; the sorting jaws 632 are arranged on the sorting base 634, and each sorting jaw 632 corresponds to a sorting base 634, and the sorting jaws 632 can be raised and lowered relative to the sorting base 634, and the lifting and lowering of the sorting jaws 632 can be achieved by a cylinder, a hydraulic cylinder or other structures.

[0195] This embodiment provides some structures of the unloading and sorting component 63, so that each battery cell 200 can be individually grasped by multiple independent sorting jaws 632, so as to obtain qualified battery cells 200 in the unloading and conveying component 62 and avoid unqualified battery cells 200, thereby achieving the sorting effect; at the same time, the independent sorting jaws 632 can also obtain battery cells 200 from the cache position according to the number of qualified battery cells 200, so that the number of battery cells 200 transferred to the first discharge port by the unloading and sorting component 63 can be kept consistent.

[0196] In some embodiments, the number of sorting jaws 632 is the same as the number of unloading conveyor belts 621, and the sorting jaws 632 are opposite to the corresponding unloading conveyor belts 621. At this time, when the number of qualified battery cells 200 on the unloading conveyor assembly 62 meets the number of battery cells 200 that the testing equipment 100 should output, multiple sorting jaws 632 can transfer the battery cells 200 from the unloading conveyor assembly 62 to the first discharge port in one action.

[0197] This embodiment further limits the number of sorting jaws 632 and makes the sorting jaws 632 face the unloading conveyor belt 621 one by one, so that each sorting jaw 632 can independently obtain qualified battery cells 200, thereby achieving the sorting effect.

[0198] In some embodiments of the present application, the unloading and sorting component 63 further includes a sorting blocker 633 , which is movably disposed on the sorting bracket 631 , and can block the unloading conveying component 62 from conveying the battery cell 200 to the second discharge port.

[0199] The sorting blocking member 633 refers to a structure or a combination of structures that can prevent the battery cell 200 from moving with the unloading conveyor belt 621; the sorting blocking member 633 can be a block, a bar or other structure; the battery cell 200 blocked by the sorting blocking member 633 no longer moves with the unloading conveyor belt 621 but remains stationary relative to the frame 10, so that the sorting clamp 632 can obtain the battery cell 200 more accurately.

[0200] The sorting block 633 can be used to block only qualified battery cells 200, preventing them from passing through the unloading and sorting assembly 63 and being conveyed to the second discharge port. Alternatively, the sorting block 633 can be used to block all battery cells 200 and, after the sorting jaws 632 have captured a qualified battery cell 200, stop blocking the remaining battery cells 200. Optionally, the time required for the sorting block 633 to block a battery cell 200 and for the sorting jaws 632 to capture a battery cell 200 can be relatively short to reduce collisions between battery cells 200 and the unloading conveyor belt 621.

[0201] The sorting blocking member 633 is movably provided on the sorting bracket 631. Since the sorting blocking member 633 can both block the battery cells 200 and allow the battery cells 200 to pass through, the sorting blocking member 633 is movable relative to the sorting bracket 631 so that the sorting blocking member 633 has at least a first position and a second position. When the sorting blocking member 633 is in the first position, the battery cells 200 are blocked. When the sorting blocking member 633 is in the second position, the sorting blocking member 633 cannot block the battery cells 200.

[0202] The movement of the sorting blocking member 633 relative to the sorting bracket 631 can be a lifting movement or a horizontal telescopic movement; the sorting blocking member 633 can be driven by a cylinder, a hydraulic cylinder or other structures.

[0203] Because the unloading conveying assembly 62 can ultimately convey the battery cells 200 to the second discharge port, and the unloading sorting assembly 63 can obtain qualified battery cells 200 during this process, so that the battery cells 200 at the second discharge port are all unqualified products. Accordingly, this embodiment provides a sorting blocker 633. When the unloading conveying assembly 62 conveys the battery cells 200 to the second discharge port, the sorting blocker 633 blocks qualified battery cells 200, so that the sorting jaws 632 can obtain the corresponding qualified battery cells 200, and the unloading conveying assembly 62 can convey unqualified battery cells 200 to the second discharge port, so as to achieve the effect of sorting qualified battery cells 200 from unqualified battery cells 200.

[0204] In some embodiments, the number of the sorting blocking members 633 is the same as the number of the unloading conveyor belts 621 , and the sorting blocking members 633 correspond to the unloading conveyor belts 621 one by one.

[0205] The one-to-one correspondence between the sorting blocking members 633 and the unloading conveyor belts 621 means that each sorting blocking member 633 can respectively block the battery cells 200 on each corresponding unloading conveyor belt 621 .

[0206] At this time, the sorting blocking member 633 is only used to block qualified battery cells 200, while unqualified batteries can directly move to the second discharge port along the unloading conveyor belt 621 and are no longer blocked.

[0207] In this embodiment, the sorting blockers 633 correspond one-to-one with the unloading conveyor belt 621 , so that the sorting blockers 633 block the qualified battery cells 200 conveyed on the unloading conveyor belt 621 , thereby assisting the unloading conveyor belt 621 and the sorting clamps 632 to achieve the sorting effect.

[0209] In some embodiments of the present application, the loading module 40 includes a loading and transferring component 41, a loading conveying component 42 and a loading transfer component 46. The loading and transferring component 41 is used to obtain the battery cell 200 and transfer the battery cell 200 to the loading and conveying component 42. The loading and conveying component 42 is used to obtain the battery cell 200 from the loading and transferring component 41 and allow the battery cell 200 to pass through the first detection module 20. The loading transfer component 46 is used to obtain the battery cell 200 from the loading and conveying component 42 and transfer the battery cell 200 to the carrier component 50.

[0210] The loading and transferring component 41 refers to a structure or a combination of structures that can obtain and transfer battery cells 200. The loading and transferring component 41 can include a manipulator, a clamp, a trolley, a conveyor belt or other structures; the battery cells 200 obtained by the loading and transferring component 41 can come from the previous process of the assembly line, or can be provided by staff or external equipment; the loading and transferring component 41 can also transfer the obtained battery cells 200 to the loading and conveying component 42. The number of battery cells 200 transferred by the loading and transferring component 41 at a time can be one, two or more.

[0211] The loading and conveying component 42 refers to a structure or a combination of structures that can obtain batteries and convey battery cells 200. The loading and conveying component 42 may include a conveyor belt, a trolley or other structures; the battery cells 200 obtained by the loading and conveying component 42 come from the loading and transferring component 41; in the process of the loading and conveying component 42 conveying the battery cells 200, the battery cells 200 can pass through the first detection module 20 and be detected by the first detection module 20. In the process of the first detection module 20 detecting the battery cells 200, the loading and conveying component 42 does not need to be shut down, that is, the first detection module 20 can complete the detection during the movement of the battery cells 200.

[0212] The loading and transfer component 46 refers to a structure or a combination of structures that can obtain and transfer battery cells 200. The loading and transfer component 46 can include a manipulator, a clamp, a trolley, a conveyor belt or other structures; the battery cells 200 obtained by the loading and transfer component 46 come from the loading and conveying component 42, that is, after the loading and conveying component 42 drives the battery cells 200 through the first detection module 20, the loading and transfer component 46 can obtain the battery cells 200 from the loading and conveying component 42; the loading and transfer component 46 can also transfer the obtained battery cells 200 to the carrier component 50. The number of battery cells 200 transferred by the loading and transfer component 46 at a time can be one, two or more.

[0213] The loading and transferring component 41, the loading and conveying component 42 and the loading and transferring component 46 can be arranged in sequence along a straight line, or can be arranged in an L-shape or other shape as needed; in some embodiments, the loading and transferring component 41 and the loading and conveying component 42 are arranged along a straight line, the loading and transferring component 46 is arranged on one side of the loading and conveying component 42, and the loading and transferring component 46 is arranged between the loading and conveying component 42 and the carrier component 50.

[0214] The loading module 40 is provided with a loading conveying assembly 42 so that the battery cells 200 can undergo partial testing first during the process, thereby reducing the situation where a large number of testing devices 100 perform centralized testing on the battery cells 200, resulting in a long cycle, and also reducing the repeated setting of the same testing device.

[0215] The loading and transferring component 41, the loading and conveying component 42 and the loading and transferring component 46 decompose the loading process, and also insert some appearance inspection items in the loading process. Specifically, the loading and transferring component 41 is used to transfer the battery cell 200 to the loading and conveying component 42, the loading and conveying component 42 is used to convey the battery cell 200 and accept the inspection of the first inspection module 20, and the loading and transferring component 46 is used to transfer the battery cell 200 to the carrier component 50. Compared with the loading achieved through a complex structure, this setting makes the action of each component relatively simple, and the three components can move synchronously, so that the inspection equipment 100 has a faster beat, improves the inspection efficiency, and is also convenient for setting different inspection beats according to needs.

[0216] This embodiment provides some structures of the loading module 40, which obtains the battery cell 200 through the loading and transferring component 41 and transfers the battery cell 200 to the loading and conveying component 42. It also drives the battery cell 200 through the first detection module 20 through the loading and conveying component 42, so that the first detection module 20 can detect the passing battery cell 200. In the process of the loading and conveying component 42 conveying the battery cell 200, the loading and transferring component 41 can repeat the action of obtaining the battery cell 200 again to improve the detection efficiency and facilitate better design of the operation rhythm of the detection equipment 100.

[0217] In some embodiments of the present application, the loading module 40 also includes a transfer component 43; the loading and transferring component 41 includes two loading and transferring clamps 411, either of which is used to obtain the battery cell 200 and transfer the battery cell 200 to the transfer component 43, and the other of the two is used to obtain the battery cell 200 from the transfer component 43 and transfer the battery cell 200 to the loading and conveying component 42.

[0221] The setting of two loading and transferring clamps 411 can further decompose the process of the loading and transferring component 41 transferring the battery cell 200 to the loading and conveying component 42. In the process of one loading and transferring clamp 411 acquiring and transferring the battery cell 200, the other loading and transferring clamp 411 can move and acquire the battery cell 200 again, thereby further shortening the time for a single acquisition and transfer of the battery cell 200, improving efficiency, and at the same time further speeding up the detection rhythm.

[0222] This embodiment further provides some structures of the loading module 40, and makes the loading and transferring component 41 include two loading and transferring clamps 411, one of which can transfer the battery cell 200 to the transfer component 43, and the other can transfer the battery cell 200 from the transfer component 43 to the loading and conveying component 42.

The loading and handling component 44 can include a manipulator, a clamp, a trolley, a conveyor belt or other structures; the battery cells 200 obtained by the loading and handling component 44 come from the loading and conveying component 42; the loading and handling component 44 can also transfer the obtained battery cells 200 to the column assembly 45; the number of battery cells 200 transferred by the loading and handling component 44 at a single time can be one, two or more.

[0228] This embodiment further provides some structures of the loading module 40, which transfers the battery cells 200 on the loading conveying component 42 through the loading and handling component 44, and receives and temporarily stores the battery cells 200 from the loading and handling component 44 through the column assembly 45, so as to shorten the operation cycle of the loading and conveying component 42, thereby facilitating a better design of the operation rhythm of the detection equipment 100.

[0229] In some embodiments, referring to Figure 9, the loading and conveying assembly 44 includes a conveying bracket 441, a conveying movable plate 442 and a conveying clamp 443. The loading bracket can be set on the frame 10. At this time, the conveying bracket 441 is arranged on the loading bracket and can move along the loading bracket. The conveying movable plate 442 is arranged on the conveying bracket 441 and can be raised and lowered relative to the conveying bracket 441. The conveying clamp 443 is arranged on the conveying movable plate 442. The conveying clamp 443 can clamp and release the battery cell 200. According to the position of the decoupling assembly 45 and the loading and conveying assembly 42, the conveying clamp 443 can also rotate relative to the conveying movable plate 442.

[0230] Among them, the transport bracket 441 can move along the loading bracket through a rodless cylinder, a screw slider or other structures, the transport movable plate 442 can be raised and lowered relative to the transport bracket 441 through a cylinder, a hydraulic cylinder or other structures, and the transport clamp 443 can be rotated relative to the transport movable plate 442 through a motor, a rotary cylinder or other structures.

[0231] In some embodiments of the present application, the column assembly 45 includes at least two loading positions 451, and at least two loading positions 451 are arranged in sequence along the third direction; the column assembly 45 also includes at least two column belts 452, at least two column belts 452 are arranged in sequence along the fourth direction, and the column belts 452 correspond one-to-one to the loading positions 451; the third direction is the extension direction of the column belt 452, and the fourth direction is perpendicular to the third direction.

[0232] The loading position 451 refers to a position on the decoupling assembly 45 for placing the battery cells 200 . When the loading and transporting assembly 44 transfers the battery cells 200 to the decoupling assembly 45 , the loading and transporting assembly 44 can transfer the battery cells 200 to the loading position 451 .

[0233] The column belt 452 refers to a conveyor belt structure capable of carrying and conveying the battery cells 200 . The column belt 452 may include a PVC conveyor belt, a belt conveyor belt, a chain plate conveyor belt, or other conveyor belts.

[0234] The one-to-one correspondence between the column belts 452 and the loading positions 451 means that each column belt 452 is provided with a loading position 451; in some embodiments, the loading position 451 may simply refer to a position set in space; in other embodiments, a component capable of limiting the position of the battery cell 200 may be provided above the column belt 452 to form a loading position 451. In this case, the battery cell 200 should be able to move with the movement of the column belt 452 and leave the loading position 451.

[0235] The third direction refers to the direction in which the column belt 452 extends, and is also the direction in which the column belt 452 transports the battery cells 200. The fourth direction refers to the direction in which the column belt 452 is arranged, and the third direction is perpendicular to the fourth direction; referring to Figure 13, the third direction is the direction of the X-axis in the figure, and the fourth direction is the direction of the Y-axis in the figure.

[0236] It can be understood that, depending on the setting position and orientation of the column assembly 45 and the unloading conveying assembly 62, the third direction can be parallel to the first direction, or intersect with the first direction, that is, the fourth direction can be parallel to the second direction, or intersect with the second direction.

[0237] Because there are at least two column belts 452, and each column belt 452 is provided with a loading position 451, that is, the loading positions 451 are arranged in sequence in the fourth direction, and at the same time, the loading positions 451 are also arranged in sequence along the third direction, that is, at least two loading positions 451 are arranged obliquely and staggered, and each unloading position 622 does not overlap in the third direction and the fourth direction.

[0238] In some embodiments, referring to FIG13, the column assembly 45 includes four column belts 452. Along the direction from near to far of the carrier assembly 50, the four column belts 452 are sequentially referred to as the first column belt, the second column belt, the third column belt and the fourth column belt. Correspondingly, the loading positions 451 on the four unloading column belts 452 are respectively referred to as the first loading position, the second loading position, the third loading position and the fourth loading position. The four column belts 452 all transport the battery cells 200 in the direction from top to bottom; at this time, the fourth loading position is at the first loading position. Below the three loading positions, the third loading position is below the second loading position, and the second loading position is below the first loading position. As the four column belts 452 move, there is no battery cell 200 between the four loading positions 451 and the carrier assembly 50. Optionally, the length of the first column belt can be the same as the length of a battery cell 200. At this time, the first column belt no longer transports the battery cell 200 but only plays a supporting role. On this basis, the first column belt can actually be replaced by a platform, cavity and other structures.

[0239] During the process of transferring the battery cells 200 to the carrier assembly 50 by the loading and transporting assembly 46, the transferred battery cells 200 may pass over other battery cells 200 on the arrangement assembly 45, i.e., a situation of crossing the battery cells 200 may occur. If the transferred battery cells 200 fall at this time, collisions between the battery cells 200 may occur, and safety accidents such as fire and explosion may occur.

[0240] Accordingly, this embodiment sets a loading position 451 on the column assembly 45, and arranges different loading positions 451 in an alternating manner, so that when the loading and transfer assembly 46 transfers the battery cell 200 to the carrier assembly 50, it is unlikely that other battery cells 200 will appear under the transferred battery cell 200, thereby reducing the occurrence of safety accidents caused by the falling of the battery cell 200 and improving the safety performance of the detection equipment 100.

[0241] In some embodiments of the present application, the loading and transfer assembly 46 includes a loading and variable-distance clamping jaw, which is used to transfer the battery cells 200 in different loading positions 451 to different carrier assemblies 50 .

[0242] The variable-distance loading clamp refers to a structure or combination of structures that can shift different battery cells 200 to different distances. During the single transfer of battery cells 200 by the loading and transfer assembly 46, the distance between each loading position 451 and the carrier assembly 50 is different. Accordingly, the variable-distance loading clamp can shift different battery cells 200 to different distances.

[0243] In some embodiments, the loading variable-distance gripper may include multiple grippers with different strokes, each gripper being used to obtain a battery cell 200. During a single transfer process of the loading and transfer assembly 46, multiple grippers operate simultaneously but with different strokes, so that multiple grippers can simultaneously obtain battery cells 200 from different loading positions 451 and can simultaneously transfer the battery cells 200 to the carrier assembly 50; in other embodiments, the loading variable-distance gripper may also include multiple grippers with the same stroke. In this case, the time for each gripper to open and put down the battery cell 200 is different, that is, multiple grippers can move with the same stroke and can obtain battery cells 200 from different loading positions 451 at different times; in some other embodiments, the loading variable-distance gripper may also obtain battery cells 200 from different loading positions 451 through other structures.

[0244] In some embodiments, the number of jaws in the variable-pitch loading jaw is the same as the number of the column belts 452 , so that during a single transfer process of the variable-pitch loading jaw, each jaw can obtain a corresponding battery cell 200 from one column belt 452 .

[0245] Because different loading positions 451 are staggered, that is, the distances between each loading position 451 and the carrier assembly 50 are different, this embodiment can simultaneously obtain battery cells 200 from the array assembly 45 through the loading variable-distance clamp, and simultaneously transfer each battery cell 200 to different positions of the carrier assembly 50, so that the battery cells 200 can remain synchronized during the transfer process, so as to facilitate the design of the production rhythm of this step, and also facilitate the cooperation with the action of the array assembly 45 to improve the safety performance of the detection equipment 100.

[0246] In some embodiments, the loading variable-distance clamp includes a transfer bracket 461, a transfer movable plate 462 and at least two transfer clamps 463. The transfer bracket 461 is arranged on the loading bracket and can move along the loading bracket. The transfer movable plate 462 is arranged on the transfer bracket 461 and can be raised and lowered relative to the transfer bracket 461. At least two transfer clamps 463 are arranged on the transfer movable plate 462. Each time the transfer clamp 463 is used to obtain a battery cell 200, and each transfer clamp 463 has a different stroke.

[0247] Among them, the transfer bracket 461 can move along the loading bracket through a rodless cylinder, a screw slider or other structures, the transfer movable plate 462 can be raised and lowered relative to the transfer bracket 461 through a cylinder, a hydraulic cylinder or other structures, and the transfer clamp 463 can be moved relative to the transfer bracket 461 through a cylinder, a hydraulic cylinder or other structures, and each transfer clamp 463 can have a different stroke.

[0248] According to some embodiments of the present application, referring to FIG. 2 and FIG. 5 , FIG. 2 is a schematic diagram of the detection device 100 in some embodiments of the present application, and FIG. 5 is a stereoscopic schematic diagram of the standard calibration module 70 in some embodiments of the present application.

[0249] In some embodiments of the present application, the detection device 100 further includes a standard verification module 70 , which is used to convey the standard battery 71 to the loading module 40 , and the standard verification module 70 is also used to receive the standard battery 71 conveyed from the unloading module 60 .

[0250] The standard battery 71 refers to a battery cell 200 that has been tested and confirmed to be qualified. The standard battery 71 is used to verify the detection capability of the detection device 100 to confirm whether there is any deviation in the detection device 100 that causes inaccurate detection results.

[0251] The standard verification module 70 refers to a structure or a combination of structures that can provide standard batteries 71 to the upper feeding module 40. The standard verification module 70 can be a conveyor belt, a trolley, a clamp, a manipulator or other structures; the standard verification module 70 stores standard batteries 71. The standard verification module 70 can convey standard batteries 71 to the upper feeding module 40, and can also receive standard batteries 71 transferred from the unloading module 60 after being inspected by the inspection equipment 100.

[0252] The number of standard batteries 71 stored in the standard verification module 70 should be the same as the number of battery cells 200 provided to the loading module 40 by the previous process or the staff, so as to reduce the negative impact that the difference in quantity may have on the verification.

[0253] The standard verification module 70 can be activated once each time the battery cell 200 is tested, and the standard verification module 70 can also be activated at a certain time according to demand; in some embodiments, the standard verification module 70 can be automatically activated once every day after the detection device 100 is turned on to achieve daily calibration of the detection device 100; in other embodiments, the standard verification module 70 can also be manually activated and activated once by the staff when a large number of unqualified battery cells 200 appear.

[0254] In order to make the detection equipment 100 have higher detection accuracy, it is necessary to frequently calibrate the detection equipment 100. Accordingly, this embodiment provides a standard calibration module 70. The standard calibration module 70 can convey the standard battery 71 to the loading module 40. The standard battery 71 has qualified parameters. After being conveyed to the loading module 40, the standard battery 71 can pass through the actions of the carrier module 51 and the unloading module 60 in turn and finally return to the standard calibration module 70. During this process, the first detection module 20 and the second detection module 30 can detect the standard battery 71. The staff can determine whether there is any abnormality in the detection equipment 100 based on the monitoring results to achieve the effect of calibration of the detection equipment 100.

[0255] In some embodiments of the present application, the standard calibration module 70 includes at least two calibration conveyor belts 72 , and each calibration conveyor belt 72 is used to transport a standard battery 71 .

[0256] The verification conveyor belt 72 may include a PVC conveyor belt, a belt conveyor belt, a chain plate conveyor belt or other conveyor belts. When the standard verification module 70 is not in operation, the verification conveyor belt 72 does not work and only serves to support and store the standard battery 71.

[0257] In some embodiments, the transfer component 43 includes at least two transfer conveyor belts, and the number of transfer conveyor belts and the number of verification conveyor belts 72 are the same as the number of unloading conveyor belts 621, and the two ends of the verification conveyor belt 72 are respectively connected to the transfer conveyor belt and the unloading conveyor belt 621; when the standard verification module 70 is in operation, the verification conveyor belt 72 can convey the standard battery 71 to the transfer conveyor belt, and then the loading and transferring clamp 411 in the loading module 40 can obtain the standard battery 71 from the transfer conveyor belt and transfer the standard battery 71 to the loading and handling component 44; when the detection equipment 100 completes the detection of the standard battery 71, the unloading variable-distance clamp 611 in the unloading module 60 transfers the standard battery 71 to the unloading conveying component 62, and the unloading conveying component 62 conveys the standard battery 71 to the transfer conveyor belt, and the calibration process of the detection equipment 100 is completed.

[0258] In this embodiment, the standard calibration module 70 includes multiple calibration conveyor belts 72 to correspond to the transfer component 43 and the unloading conveyor component 62, so that the calibration conveyor belt 72 can transport the standard battery 71 to the transfer component 43, and also facilitate the unloading conveyor component 62 to send the standard battery 71 back to the calibration conveyor belt 72.

[0259] According to some embodiments of the present application, refer to FIG2 , which is a schematic diagram of a detection device 100 in some embodiments of the present application.

[0260] In some embodiments of the present application, the carrier assembly 50 includes at least two carriers 51 , each of which is used to carry a battery cell 200 and drive the battery cell 200 to pass through the second detection module 30 .

[0261] The carrier 51 refers to a structure or structural component used to carry the battery cell 200 and drive the battery cell 200 to move. The carrier 51 can be a clamp, a trolley, a clamp or other structure provided on the conveyor belt; the battery cell 200 obtained by the carrier 51 comes from the loading module 40, specifically from the loading transfer component 46 of the loading module 40.

[0262] Each carrier 51 can be used to carry only one battery cell 200, or two or more battery cells 200. Depending on the number of battery cells 200 carried by a single carrier 51 and the number of battery cells 200 that the loading module 40 transfers to the carrier assembly 50 at a single time, there can be one or more carriers 51. In some embodiments, the number of carriers 51 is the same as the number of battery cells 200 that the loading module 40 transfers at a single time, and each carrier 51 is used to carry one battery cell 200. Multiple carriers 51 can move synchronously and drive the battery cells 200, and each carrier 51 can also move independently.

[0263] The carrier 51 can drive the battery cell 200 through the second detection module 30 and enable the battery cell 200 to be detected by the second detection module 30; according to the specific type of each component in the second detection module 30, the carrier 51 can stop moving when reaching a certain component to facilitate detection, and the carrier 51 may also pass through each component without stopping.

[0264] In this embodiment, some structures of the carrier assembly 50 are provided, so that the carrier assembly 50 includes at least two carriers 51, so that the carrier assembly 50 can simultaneously transport multiple battery cells 200, and also facilitate the second detection module 30 to detect multiple battery cells 200, thereby improving detection efficiency.

[0265] In some embodiments, a sensor can be set on the carrier 51 to confirm whether there is a battery cell 200 in the carrier 51, thereby reducing the situation where the loading module 40 places the battery cell 200 into the carrier 51 with the battery cell 200, thereby reducing the collision between the battery cells 200 and improving the safety performance of the detection equipment 100; in other embodiments, the sensor can also be used to detect whether the position of the battery cell 200 is correct, such as whether there is skewness, misalignment, etc., to reduce the occurrence of false detection when the battery cell 200 passes through the second detection module 30, and reduce the negative impact on the detection results.

[0266] In some embodiments, the carrier assembly 50 may further include a track 55, and the carrier 51 may be disposed on the track 55 and move along the track 55.

The pole detection assembly 32 may include a machine vision device such as a camera, or other detection devices. In some embodiments, the pole detection assembly 32 may include multiple image collectors with different orientations to obtain image information of the pole 2011 from multiple different directions to better confirm the appearance of the pole 2011. In other embodiments, the pole detection assembly 32 may be located above the track 55 of the carrier assembly 50 to facilitate the collection of information about the pole 2011 of the battery cell 200.

[0278] This embodiment provides some structures of the second detection module 30 so that the second detection module 30 can detect the pole 2011 , the explosion-proof valve 2012 , the top surface and two other opposite side surfaces of the passing battery cell 200 .

[0279] According to some embodiments of the present application, refer to FIG2 , which is a schematic diagram of a detection device 100 in some embodiments of the present application.

[0280] In some embodiments of the present application, the unloading module 60 is also used to obtain the battery cell 200 and transfer the battery cell 200 to the carrier assembly 50; the carrier assembly 50 is also used to receive the battery cell 200 transferred from the unloading module 60 and transport the battery cell 200 through the second inspection module 30; the loading module 40 is also used to obtain the battery cell 200 from the carrier assembly 50 and drive the battery cell 200 through the first inspection module 20.

[0281] When a large number of unqualified battery cells 200 appear continuously among the battery cells 200 detected by the detection device 100, the detection device 100 also has the ability to reverse action. At this time, the unloading module 60 can transfer the battery cells 200 to the carrier assembly 50, and the carrier assembly 50 can transport the battery cells 200 to the loading module 40.

[0292] In some embodiments, after the second feeding module 90 transports the battery cells 200 to other locations, the staff can collect these battery cells 200 and place these battery cells 200 again at the loading module 40 at a certain time for further inspection.
