[0004] To solve the above technical problem, this application is implemented as follows:

One end of the elastic member is connected to the thimble body, and the other end of the elastic member is connected to the sleeve. At least a part of the thimble body is exposed outside the sleeve. The part of the thimble body exposed outside the sleeve is used to contact the battery, and the thimble body is used to be electrically connected to the detection instrument.

[0010] Optionally, the battery detection device further includes an appearance detection mechanism, a gripper, and a controller. The battery detection device has a third direction.

The multiple feeding stations are arranged corresponding to the transportation path of the battery, and the number of the appearance detection mechanisms is the same as the number of the feeding stations. The positions of the multiple feeding stations and the positions of the multiple appearance detection mechanisms correspond one by one.

[0013] Optionally, the number of the appearance detection mechanisms is single.

Since the detection mechanism includes multiple thimbles, the thimbles are located on one side of the feeding station, and the thimbles correspond to the feeding stations one by one. Therefore, when parameter detection of the battery is required, the thimbles can move towards the side close to the feeding station, so that the thimbles can extend into the feeding station to contact the batteries therein, thereby realizing the detection of the batteries. In addition, the number of thimbles is multiple. Therefore, the multiple thimbles can simultaneously perform parameter detection on the batteries in the multiple feeding stations. Thus, the battery detection device can realize parameter detection of multiple batteries at one time, improving the detection efficiency of the batteries.

Detailed implementation manner

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0029] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present application. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout the specification do not necessarily refer to the same embodiment. In addition, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0030] As Figures 1 to 8 As shown, the battery detection device 100 includes a frame 10, a detection mechanism 20, and a transport mechanism 30. The detection mechanism 20 and the transport mechanism 30 are both installed on the frame 10. The transport mechanism 30 is used to transport the battery 200. A plurality of loading stations 31 are provided on the transport mechanism 30, and the loading stations 31 are used to carry the battery 200; the detection mechanism 20 includes a plurality of thimbles 211, and the plurality of thimbles 211 correspond to the plurality of loading stations 31 one by one, and the thimbles 211 are used to detect the battery 200.

[0031] Among them, in the embodiment of the present application, each thimble 211 is movable relative to the loading station 31, and the plurality of thimbles 211 are respectively located on one side of the plurality of loading stations 31.

[0032] In the embodiment of the present application, since a plurality of loading stations 31 are provided on the transport mechanism 30, the transport mechanism 30 can carry a plurality of batteries 200 through the plurality of loading stations 31, fix the plurality of batteries 200, and transport the plurality of batteries 200, so that the detection mechanism 20 can detect the plurality of batteries 200.

[0033] Since the detection mechanism 20 includes a plurality of thimble 211, the thimble 211 is located on one side of the feeding station 31, and the thimble 211 corresponds to the feeding station 31 one by one. Therefore, when it is necessary to detect the parameters of the battery 200, the thimble 211 can move towards the side close to the feeding station 31, so that the thimble 211 can extend into the feeding station 31 to contact the battery 200 therein, thereby realizing the detection of the battery 200. In addition, the number of thimbles 20 is multiple. Therefore, a plurality of thimbles 211 can simultaneously detect the parameters of the batteries 200 in a plurality of feeding stations 31, so that the battery detection device 100 can detect the parameters of a plurality of batteries 200 at one time, improving the detection efficiency of the batteries 200.

[0034] That is, in the embodiment of the present application, by providing a plurality of thimbles 211 and providing a plurality of feeding stations 31 on the conveying mechanism 30, the plurality of feeding stations 31 correspond to the plurality of thimbles 211 one by one. Thus, once the plurality of feeding stations 31 simultaneously transport a plurality of batteries 200, the plurality of thimbles 211 can simultaneously detect the plurality of batteries 200, effectively improving the detection efficiency of the batteries 200.

[0035] The battery detection device 100 proposed in the present application can be applied in the process of grading detection of batteries to detect parameters such as the internal resistance, test voltage, current, charge and discharge time of the batteries. In the battery grading detection device in the related art, there is also a detection library position for detecting the battery, but the detection library position only corresponds to one battery placement position, and the detection efficiency of the battery is relatively low.

[0036] In the battery detection device 100 provided in the present application, the conveying mechanism 30 is provided with a plurality of feeding stations 31 for placing the batteries 200, and the detection mechanism 20 includes a plurality of thimbles 211 opposite to the feeding stations 31, which can simultaneously detect the parameters of the batteries in the plurality of feeding stations 31, thereby solving the problem of relatively low detection efficiency of the batteries in the related art.

[0037] It should be noted that as Figure 1 、 Figure 2 shown, the number of the feeding stations 31 on the conveying mechanism 30 is multiple, and the multiple feeding stations 31 are used to simultaneously carry a plurality of batteries 200 for simultaneously detecting the plurality of batteries 200.

[0038] Specifically, the number of the feeding stations 31 can be 6. The 6 feeding stations 31 can be spaced apart and distributed in a single row. Correspondingly, the number of the ejector pins 211 can also be 6. The 6 ejector pins 211 are also spaced apart and distributed in a single row to detect the batteries in the 6 feeding stations 31. Alternatively, the 6 feeding stations 31 can be distributed in two rows, with each row having 3 feeding stations 31 spaced apart. Correspondingly, the 6 ejector pins 211 are also distributed in two rows, and each row of ejector pins 211 corresponds to the two rows of feeding stations 31.

[0039] Of course, the number of the feeding stations 31 on the conveying mechanism 30 can also be other numbers, such as 8, 9, 10, 4, 12, etc. The specific number and the specific setting method of the feeding stations 31 are not specifically limited in the embodiments of the present application.

[0040] In addition, in the embodiments of the present application, the number of the detection mechanisms 20 can be two groups. Each group of detection mechanisms 20 includes a plurality of detection mechanisms 20 arranged along the transmission direction of the conveying mechanism 30, and the two groups of detection mechanisms 20 are symmetrically arranged.

[0041] Through such a setting, when the multiple feeding stations 31 on the conveying mechanism 30 are arranged in two rows, each row of feeding stations 31 includes a plurality of feeding stations 31, and one row of feeding stations 31 corresponds to one group of detection mechanisms 20, so that the multiple batteries 200 on the two rows of feeding stations 31 can be detected simultaneously, improving the detection efficiency of the batteries 200.

[0042] In addition, in some embodiments, the detection mechanism 20 can further include a driving component 22 and a detection instrument 23. The driving component 22 is fixed to the frame 10, and the output end of the driving component 22 is connected to the ejector pin 211. The driving component 22 is used to drive the ejector pin 211 to move into contact with the battery 200. Among them, the ejector pin 211 can be electrically connected to the detection instrument 23, and the detection instrument 23 is used to detect the battery 200 contacted by the ejector pin 211.

[0043] Since the output end of the driving component 23 is connected to the ejector pin 211, the ejector pin 211 can be driven by the driving component 22 to move, so that the ejector pin 211 can extend into the feeding station 31 and contact the battery 200 carried in the feeding station 31. Thus, a detection circuit can be formed among the ejector pin 211, the battery 200, and the detection instrument 23, and the parameters of the battery 200 can be read by the detection instrument 23.

[0044] After the detection is completed, the driving component 22 can be used to drive the ejector pin 22 to move, so that the ejector pin 211 is separated from the battery 200. That is, by providing the driving component 23, and connecting the output end of the driving component 23 to the ejector pin 211, when the battery 200 needs to be detected, the driving component 23 can be operated to automatically detect the battery 200.

[0045] It should be noted that the driving component 22 may be a driving cylinder or a linear motor, or may be other structures that can move linearly. The specific structure of the driving component 22 is not specifically limited in the embodiment of the present application.

[0046] In addition, in some embodiments, the detection mechanism 20 may include a mounting block 212 connected to the ejector pin 211 , the mounting block 212 is connected to the output end of the driving assembly 22 , and the ejector pin 211 is fixed to the mounting block 212 .

[0047] The mounting block 212 may be provided with a through hole 213, and the ejector pin 211 is passed through the through hole 213, so that the ejector pin 211 is fixed to the mounting block 212. In addition, the end of the ejector pin 211 facing the conveying mechanism 30 is used to contact the battery 200, and the end of the ejector pin 211 facing away from the conveying mechanism 30 is electrically connected to the detection instrument 23.

[0048] When installing the ejector 211, the mounting block 212 can be connected to the output end of the driving assembly 22, and the ejector 211 is fixed to the mounting block 212, so that once the mounting block 212 is connected to the output end of the driving assembly 22, the connection between the ejector 211 and the driving assembly 22 can be realized, and the driving assembly 22 can drive the ejector 211 to move through the mounting block 212, so that the ejector 211 can move toward the direction close to the material discharge station 31, or move the ejector 211 away from the material discharge station 31, so that the ejector 211 can contact or separate from the battery 200. That is, by providing the mounting block 212, the ejector 211 can be conveniently connected to the driving assembly 22, so that the driving assembly 22 can drive the ejector 211 to move, so as to realize the detection of the battery 200.

[0049] In addition, one end of the ejector pin 211 facing away from the conveying mechanism 30 can be electrically connected to the detection instrument 23, and the other end of the ejector pin 211 facing the conveying mechanism 30 is used to contact the battery 200, so that when the driving assembly 200 drives the mounting block 212 to move so that the ejector pin 211 contacts the battery 200, the end of the ejector pin 211 facing the conveying mechanism 30 contacts the battery 200, so that the ejector pin 211, the detection instrument 23 and the battery 200 form a detection circuit, and the detection instrument 23 can detect the parameters of the battery through the ejector pin 211.

[0050] In addition, in some embodiments, Figure 7As shown, the ejector pin 211 may include: an ejector pin body 214, a sleeve 215, and an elastic member 216. The sleeve 215 is sleeved on the ejector pin body 214. One end of the elastic member 216 is connected to the ejector pin body 214, and the other end of the elastic member 216 is connected to the sleeve 215. At least a part of the ejector pin body 214 is exposed outside the sleeve 215, and the part of the ejector pin body 214 exposed outside the sleeve 215 is used to contact the battery 200 on the conveying mechanism 30. The ejector pin body 214 is electrically connected to the detection instrument 23.

[0051] Among them, the sleeve 215 is a hollow structure, and the ejector pin body 214 and the elastic member 216 can be arranged inside the sleeve 215. When installing the ejector pin 211, the sleeve 215 can be passed through the through hole 213 on the mounting block 212 to realize the connection between the ejector pin 211 and the mounting block 212, that is, the ejector pin 211 is connected to the mounting block 212 through the sleeve 215. Inside the sleeve 215, one end of the elastic member 216 is connected to the ejector pin body 214, and the other end of the elastic member 216 is connected to the bottom of the sleeve 215. That is, the elastic member 216 is connected between the ejector pin body 214 and the sleeve 215, and an elastic connection between the ejector pin body 214 and the sleeve 215 can be realized. Setting the elastic member 216 can play a flexible protection role for the battery 200 and prevent the ejector pin body 214 from bruising the surface of the battery 200.

[0052] The ejector pin body 214 is electrically connected to the detection instrument 23. Since at least a part of the ejector pin body 214 is exposed outside the sleeve 215, and the part of the ejector pin body 214 exposed outside the sleeve 215 faces the conveying mechanism 30, therefore, the exposed part of the ejector pin body 214 can be used to contact the battery 200, so that the ejector pin body 214, the battery 200, and the detection instrument 23 form a detection circuit, and the detection instrument 23 can detect the battery 200 through the ejector pin body 214.

[0053] In the embodiment of the present application, an elastic member 216 is provided at the bottom of the ejector pin body 214 and the sleeve 215, which can make the ejector pin 211 elastic. Specifically, when the ejector pin body 214 contacts the battery 200, the ejector pin body 214 can compress the elastic member 216, causing the elastic member 216 to generate an elastic force. The elastic member 216 can provide a force opposite to the elastic force to the ejector pin body 214, so that the ejector pin body 214 can be in good contact with the battery 200, avoiding the problem of distorted detection results.

[0054] It should be noted that the elastic member 216 can be a spring or a spring sheet, or can also be other components made of elastic materials. The specific structure of the elastic member 216 is not specifically limited in the embodiment of the present application.

[0055] In addition, in some embodiments, such as Figure 6 and Figure 8As shown in the figure, the battery detection device 100 may further include an appearance detection mechanism 42, a gripper 43, and a controller 41. The battery detection device 100 has a third direction Z. The appearance detection mechanism 42 is connected to the frame 10, and the appearance detection mechanism 42 is disposed opposite to the conveying mechanism 30 along the third direction Z. The controller 41 is electrically connected to the gripper 43 and the appearance detection mechanism 42 respectively. The gripper 43 is used to remove the battery 200 from the conveying mechanism 300.

[0056] Since the appearance detection mechanism 42 is also opposite to the conveying mechanism 30 and is electrically connected to the controller 41, once the battery 200 is transported to the appropriate position, the controller 41 can control the operation of the appearance detection mechanism 42, so that the appearance detection mechanism 41 collects the appearance of the battery 200 on the conveying mechanism 30 to detect whether there are defects in the appearance of the battery 200. Since the controller 41 is electrically connected to the gripper 43, the controller 41 can control the movement of the gripper 43. Thus, once it is determined that there are defects in the appearance of the battery 200 on the conveying mechanism 30, the controller 41 can control the movement of the gripper 43 to clamp the battery 200 on the conveying mechanism 30 and remove the defective battery 200 from the conveying mechanism 300, ensuring that the battery 200 transported to the next station by the conveying mechanism 30 has fewer defects or no defects.

[0057] It should be noted that in the embodiment of the present application, the detection mechanism 20 can detect the parameters of the battery 200 through the ejector pin 211. During the parameter detection process, the ejector pin 211 needs to be inserted into the detection terminal of the battery 200. However, electrolyte may overflow when the ejector pin 211 is inserted into the detection terminal. If it cannot be discovered in time, it will pose a hidden danger to the subsequent processes. In the battery detection device 100 proposed in the present application, an appearance detection mechanism 42 is also provided to detect the appearance of the battery 200. After receiving the appearance image collected by the appearance detection mechanism 42, the controller 41 can judge whether there is electrolyte overflow in the battery 200 according to the appearance image, so as to timely detect the battery 200 with defects during the parameter detection process. Then, the controller 41 can control the movement of the gripper 43 accordingly to remove the defective battery 200, preventing the defective battery 200 from entering the next process.

[0058] It should be noted that as Figure 1 shown, the battery detection device 100 can be installed and stand on the ground through the frame 10. The third direction Z can be the vertical direction, perpendicular to the ground; while the first direction X and the second direction Y can be parallel to the ground. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other and can form a space coordinate system. The gripper 43 can move in this space coordinate system to grab the battery 200 and move the battery 200.

[0059] In addition, in the embodiments of the present application, the gripper 43 may be provided on the frame 10. Of course, the gripper 43 may also be provided on the ground and is located on one side of the frame 10. The specific position of the gripper 43 is not limited in the embodiments of the present application.

[0060] In addition, in some embodiments, the gripper 43 may include a hand claw and a connecting rod connected to the hand claw. Both the hand claw and the connecting rod are electrically connected to the controller 41. The connecting rod is movably connected to the frame 10, and the hand claw can grip or release the battery 200; the connecting rod drives the hand claw to move and removes the battery 200 from the conveying mechanism.

[0061] Specifically, the connecting rod may be connected to the frame 10 and can move relative to the frame 10 in the first direction X, the second direction Y, and the third direction Z. The hand claw is connected to the connecting rod, and the hand claw can be driven by the connecting rod to move relative to the frame so that the hand claw can move to a position opposite to the defective battery 200. Since both the hand claw and the connecting rod are electrically connected to the controller 41, the controller 41 can control the movement of the hand claw and the connecting rod to remove the defective battery 200 from the conveying mechanism. Among them, when the controller determines that a certain battery 200 has electrolyte overflow according to the appearance image, this battery 200 is a defective battery. The controller 41 can first control the connecting rod to move so that the hand claw is opposite to the defective battery, then control the hand claw to grip the defective battery, and then control the connecting rod to move. At this time, the hand claw can drive the defective battery away from the conveying mechanism 30. When the hand claw moves to the defective battery collection area, then control the hand claw to release the defective battery and collect the defective battery to prevent the defective battery 200 from entering the next process.

[0062] In addition, in some embodiments, as Figure 2 shown, the appearance detection mechanism 42 is fixed to the frame 10, and there is a target distance L between the appearance detection mechanism 42 and the conveying mechanism 30, where L satisfies: 30 cm ≤ L ≤ 200 cm.

[0063] The appearance detection mechanism 42 is fixed to the frame 10, and there is a target distance L between the appearance detection mechanism 42 and the conveying mechanism 30. L satisfies: 30 cm ≤ L ≤ 200 cm, that is, there is a gap of 30 cm to 200 cm between the appearance detection mechanism 42 and the conveying mechanism 30. When L satisfies 30 cm ≤ L ≤ 200 cm, it is convenient for the appearance detection mechanism 42 to collect the appearance image of the battery 200, and it can avoid the problem that the distance between the appearance detection mechanism 42 and the battery 200 is too close, and only a partial image of the battery 200 can be collected, resulting in inaccurate defect detection results for the battery 200; it can also avoid the problem that the appearance detection mechanism 42 is too far from the battery 200, and the collected appearance image is not clear enough to accurately determine whether the battery 200 is defective.

[0064] It should be noted that the target distance between the appearance detection mechanism 42 and the conveying mechanism 30 can be any value within the range of 30 cm to 200 cm or any range composed of any two values. For example, it can be 30 cm, 49 cm, 60 cm, 98 cm, 180 cm, 200 cm, 100 cm - 10 cm, etc. The specific value of the target distance is not specifically limited in the embodiments of the present application.

[0065] In addition, in some embodiments, the number of appearance detection mechanisms 42 can be multiple. The multiple feeding stations 31 are arranged corresponding to the transportation path of the battery 200, and the number of appearance detection mechanisms 42 is the same as the number of feeding stations 31. The positions of the multiple feeding stations 31 and the positions of the multiple appearance detection mechanisms 42 correspond one by one.

[0066] Since the positions of the multiple feeding stations 31 and the positions of the multiple appearance detection mechanisms 42 correspond one by one, when the multiple feeding stations 31 carry multiple batteries 200, the multiple batteries 200 can correspond to the multiple appearance detection mechanisms 42 one by one. Thus, each battery 200 can be photographed by the corresponding appearance detection mechanism 42, and the multiple batteries 200 can be photographed by the multiple appearance detection mechanisms 42 simultaneously, which is convenient for obtaining the images of the multiple batteries 200 at the same time.

[0067] Moreover, the multiple batteries 200 and the multiple appearance detection mechanisms 42 corresponding one by one can also ensure that each appearance detection mechanism 42 only photographs the image of the battery 200 corresponding to it, thereby ensuring that the image of the battery 200 photographed by the appearance detection mechanism 42 is relatively clear, which is convenient for the subsequent controller 41 to determine whether the battery 200 is defective. That is, in the embodiments of the present application, when the conveying mechanism 30 moves to the target position, the positions of the feeding stations 31 and the positions of the appearance detection mechanisms 42 correspond one by one. That is, for the multiple batteries 200 on the feeding stations 31, each battery 200 corresponds to an appearance detection mechanism 42. The appearance images of the multiple batteries 200 can be collected respectively by the multiple appearance detection mechanisms 42 to determine whether the battery 200 is defective, so as to determine whether the battery 200 is defective more accurately.

[0068] In addition, in some embodiments, the number of appearance detection mechanisms 42 is single. When the conveying mechanism 30 moves to the target position, the multiple feeding stations 31 are arranged circumferentially around the appearance detection mechanism 42. The appearance detection mechanism 42 can rotate and is used to collect the appearance of the battery 200.

[0069] Since the number of appearance detection mechanisms 42 is single, multiple feeding stations 31 can be arranged circumferentially around the appearance detection mechanism 42, so that a single appearance detection mechanism 42 can be used to collect the appearances of multiple batteries 200 on the conveying mechanism 30 to determine whether the batteries 200 are defective. That is, a single appearance detection mechanism 42 can be used to collect the appearances of multiple batteries 200, which can reduce the number of appearance detection mechanisms 42 and thus reduce costs.

[0070] In addition, in some embodiments, as Figure 3 shown, the battery detection device 100 has a first direction X, which is the transportation path of the battery 200. The conveying mechanism 30 may further include a conveyor belt 50 and multiple carrier plates 51. The conveyor belt 50 is connected to the frame 10, and the carrier plates 51 are connected to the conveyor belt 50. One carrier plate 51 has one feeding station 31, and the carrier plate 51 drives the battery 200 to move along the first direction X through the conveying mechanism 30.

[0071] Since the conveyor belt 50 is connected to the frame 10 and the carrier plates 51 are connected to the conveyor belt 50, when the conveyor belt 50 moves, the carrier plates 51 thereon can also move accordingly. And one carrier plate 51 has one feeding station 31. Thus, after the carrier plate 51 moves, it can drive the battery 200 on the feeding station 31 to move relative to the frame 10 along the first direction X.

[0072] That is, when the carrier plate 51 moves, the positions of the feeding station 31 and the ejector pins 211 will also change. When the battery 200 moves to the target position, the feeding station 31 can be opposite to the ejector pins 211, enabling the battery 200 to be directly opposite to the ejector pins 211. At this time, the movement of the ejector pins 211 can be controlled to perform parameter detection on the battery 200. Meanwhile, the appearance detection mechanism 42 can collect the appearance image of the battery 200 to determine whether there is electrolyte leakage in the battery 200 during the process of parameter detection of the battery 200. That is, by providing the conveyor belt 50 and multiple carrier plates 51, it is convenient for the conveyor belt 50 to transport multiple batteries 200 at the same time, and further convenient for detecting multiple batteries 200.

[0073] It should be noted that in the embodiments of the present application, the conveyor belt 50 can be in the form of belt drive or chain drive to drive the carrier plate 51 to move. When the conveyor belt 50 is in the form of belt drive, it can have two belt pulleys and a transmission belt. The two belt pulleys can be arranged at intervals along the first direction X, and the transmission belt is wound around the two belt pulleys; when the conveyor belt 50 is in the form of chain drive, it can have two sprockets and a chain. The two sprockets can be arranged at intervals along the first direction X, and the chain is wound around the two sprockets. In order to make the transmission of the conveyor belt 50 more stable, when the conveyor belt 50 is in the form of belt drive, it can have a plurality of belt drives distributed at intervals along the second direction Y; when the conveyor belt 50 is in the form of chain drive, it can have a plurality of chain drives distributed at intervals along the second direction Y.

[0074] In addition, the setting of the conveyor belt 50 enables the battery detection device 100 to be applied to the logistics line to realize the pipeline detection of the battery 200. The battery 200 can be continuously placed on the carrier plate 51, and the movement of the carrier plate 51 can continuously transport the battery 200 to the target position. The detection mechanism 20 detects multiple groups of batteries 200, and the appearance detector 42 detects multiple groups of batteries 200. This process can be controlled by the controller 41, making the detection process of the battery 200 more automated and further improving the detection efficiency.

[0075] In addition, in some embodiments, such as Figure 2 、 Figure 3 As shown, a blocking member 60 can be connected to the frame 10. The blocking member 60 is disposed opposite to the conveyor belt 50. When the conveying mechanism 30 moves to the target position along the first direction X, the blocking member 60 moves in a direction perpendicular to the transportation path, and the blocking member 60 is used to abut against the carrier plate 51.

[0076] Since the blocking member 60 is connected to the frame 10 and the blocking member 60 is disposed opposite to the conveyor belt 50, when the conveyor belt 50 moves, the conveyor belt 50 and the carrier plate 51 thereon will move relative to the blocking member 60. Thus, when the carrier plate 51 moves to the target position, that is, when the carrier plate 51 moves to the feeding station 31 opposite to the ejector pin 211, the blocking member 60 moves in a direction perpendicular to the transportation path and abuts against the carrier plate 51 to stop the carrier plate 51, so that the ejector pin 211 can perform parameter detection on the stopped battery 200. That is, the blocking member 60 provided in the embodiments of the present application can limit the position of the carrier plate 51, so that the carrier plate 51 can accurately move to the target position, so that the ejector pin 211 can perform parameter detection on the battery 200, and it can prevent the problem that the positions of the battery 200 and the ejector pin 211 are misaligned after the carrier plate 51 stops and parameter detection cannot be performed.

[0077] In addition, in some embodiments, such as Figure 2 、 Figure 3As shown, a driving structure 70 is also connected to the frame 10. The output end of the driving structure 70 is connected to the blocking member 60, and the driving structure 70 drives the blocking member 60 to move along the second direction Y.

[0078] A driving structure 70 is also connected to the frame 10. The output end of the driving structure 70 is connected to the blocking member 60, so that the driving structure 70 can drive the blocking member 60 to move along the second direction Y. Since the second direction Y is perpendicular to the first direction X, when the blocking member 60 moves along the second direction Y, the blocking member 60 can move to the moving path of the carrier plate 51 or withdraw from the moving path of the carrier plate 51.

[0079] When the conveyor belt 50 moves relative to the frame 10, the driving structure 70 can first drive the blocking member 60 to move so that the blocking member 60 is located on the moving path of the carrier plate 51, that is, the blocking plate 60 is located on the transportation path of the battery 200. The conveyor belt 50 continues to move, which can drive the carrier plate 51 to move relative to the blocking member 60.

[0080] After the carrier plate 51 continues to move, the carrier plate 51 abuts against the blocking member 60. At this time, the carrier plate 51 can be blocked and stopped by the blocking member 60 so that the ejector pin 211 can detect the battery 200 on the carrier plate 51. After the ejector pin 211 finishes detecting the battery 200, the driving structure 70 can drive the blocking member 60 to move so that the driving member 60 withdraws from the moving path of the carrier plate 51. At this time, the carrier plate 51 can continue to move to transport the battery 200 out of the battery detection device 100.

[0081] It should be noted that the driving structure 70 and the blocking member 60 can be two components. The driving structure 70 can be a linear motor, and the output end of the linear motor can be connected to the blocking member 60; or the driving structure 70 and the blocking member 60 can also be one component, such as a blocking cylinder. The specific structures of the driving structure 70 and the blocking member 60 are not specifically limited in the embodiments of the present application.

[0082] In the embodiment of the present application, since there are multiple feeding stations 31 provided on the conveying mechanism 30, the conveying mechanism 30 can carry multiple batteries 200 through the multiple feeding stations 31, fix the multiple batteries 200, and transport the multiple batteries 200, so that the detection mechanism 20 can detect the multiple batteries 200. Since the detection mechanism 20 includes multiple thimble 211, the thimble 211 is located on one side of the feeding station 31, and the thimble 211 corresponds to the feeding station 31 one by one. Therefore, when it is necessary to detect the parameters of the battery 200, the thimble 211 can move towards the side close to the feeding station 31, so that the thimble 211 can extend into the feeding station 31 to contact the battery 200 therein, thereby realizing the detection of the battery 200. In addition, the number of the thimble 20 is multiple. Therefore, the multiple thimble 211 can simultaneously detect the parameters of the batteries 200 in the multiple feeding stations 31. Thus, the battery detection device 100 can realize the parameter detection of the multiple batteries 200 at one time, improving the detection efficiency of the batteries 200.

[0083] That is to say, in the embodiment of the present application, by providing multiple thimble 211 and setting multiple feeding stations 31 on the conveying mechanism 30, the multiple feeding stations 31 correspond to the multiple thimble 211 one by one. Thus, once the multiple feeding stations 31 transport the multiple batteries 200 simultaneously, the multiple thimble 211 can simultaneously detect the multiple batteries 200, effectively improving the detection efficiency of the batteries 200.
