Description

Technical Field

[0001] This utility model relates to the field of cylindrical battery technology, specifically to a cylindrical battery testing device and its testing apparatus. Background Technology

[0002] For the battery manufacturing process, battery quality inspection is of paramount importance. In the automated production process of batteries, it is inevitable that a small number of batteries will have defects in appearance, such as dents, scratches, bulges, electrolyte contamination, dirt, etc. There are even cases of missing parts being assembled, which not only affects the appearance but also has a significant impact on the safety of battery production and use. Before battery assembly, the appearance of the battery must be inspected to ensure the battery appearance qualification rate.

[0003] Currently, in cylindrical battery testing equipment, if the battery is placed on a conveyor belt and continuously transported by the conveyor belt, while the camera for appearance inspection films and inspects the battery, the inspection accuracy is not high because the conveyor belt cannot stop at the accurate position. On the other hand, if a robotic arm is used to remove the batteries from the conveyor belt one by one and place them on the positioning seat to facilitate appearance inspection, and then put the batteries back on the conveyor belt, it is more troublesome.

[0023] Please see Figure 1 and Figure 2 This invention provides a testing device for a cylindrical battery testing equipment, comprising: The battery handling assembly 10 includes a handling drive module 11, a loading handling module 12, a unloading handling module 13, and multiple intermediate handling modules 14. The handling drive module 11 is drivenly connected to the loading handling module 12, the unloading handling module 13, and the multiple intermediate handling modules 14. The loading handling module 12, the multiple intermediate handling modules 14, and the unloading handling module 13 are arranged sequentially along the driving direction of the handling drive module 11. Multiple battery carrier modules 20 are arranged sequentially along the driving direction of the transport drive module 11. In some optional embodiments, to classify cylindrical batteries that are found to be visually defective, so as to facilitate the separate transportation of defective and qualified cylindrical batteries, the battery carrier module 20 includes an NG carrier module 22 and multiple detection carrier modules 21. The multiple detection carrier modules 21 and NG carrier modules 22 are arranged sequentially along the driving direction of the transport drive module 11. Multiple appearance detection components 30 are correspondingly arranged at the multiple detection carrier modules 21. When a cylindrical battery can be placed on the NG carrier module 22, the corresponding defective cylindrical battery on the NG carrier module 22 can be removed manually or by a robotic arm.

[0024] The transport drive module 11 can drive the loading transport module 12, the unloading transport module 13 and the multiple intermediate transport modules 14 to move together to the first position and the second position. When the loading transport module 12, the unloading transport module 13 and the multiple intermediate transport modules 14 are in the first position, the loading transport module 12 and the multiple intermediate transport modules 14 are located at the multiple battery carrying modules 20. When the loading transport module 12, the unloading transport module 13 and the multiple intermediate transport modules 14 are in the first position, the multiple intermediate transport modules 14 and the unloading transport module 13 are located at the multiple battery carrying modules 20.

[0025] Multiple appearance inspection components 30 are arranged at different battery carrier modules 20. The specific structure of the appearance inspection components 30 can be designed according to actual inspection needs. For example, in some optional embodiments, the multiple appearance inspection components 30 are at least two of the following: cylindrical surface inspection component 31, end face 2D inspection component 32, and end face 3D inspection component 33. In this embodiment, the number of appearance inspection components 30 is three, namely cylindrical surface inspection component 31, end face 2D inspection component 32, and end face 3D inspection component 33.

[0026] The cylindrical surface inspection component 31 is used to detect whether there are appearance defects on the cylindrical surface of the cylindrical battery, while the end face 2D inspection component 32 and the end face 3D inspection component 33 are used to detect whether there are appearance defects on the end face of the cylindrical battery. The structures of the cylindrical surface inspection component 31, the end face 2D inspection component 32, and the end face 3D inspection component 33 may be the same or different. Their structures and detection principles are well known to those skilled in the art and will not be described in detail here.

[0027] The number of battery carrier modules 20 and intermediate transport modules 14 is designed based on the actual number of appearance inspection components 30. In this embodiment, there are three appearance inspection components 30, three intermediate transport modules 14, and four battery carrier modules 20, of which three are inspection carrier modules 21 and the other is an NG carrier module 22.

[0028] The working principle of the detection device of a cylindrical battery detection equipment according to an embodiment of the present invention is described below. In the initial state, none of the battery carrying modules 20 carry cylindrical batteries, and none of the loading and unloading modules 12, unloading and unloading modules 13, and multiple intermediate transport modules 14 carry cylindrical batteries. First, the transport drive module 11 moves the loading transport module 12, the unloading transport module 13 and multiple intermediate transport modules 14 together to the second position. At this time, the loading transport module 12 is not at the detection bearing module 21. At this time, the first batch of cylindrical batteries that need to be detected can be placed on the loading transport module 12. Next, the transport drive module 11 moves the loading transport module 12, the unloading transport module 13 and multiple intermediate transport modules 14 together to the first position. At this time, the loading transport module 12 reaches the first detection and support module 21. The loading transport module 12 places the first batch of cylindrical batteries on the first detection and support module 21. At this time, the appearance inspection module arranged at the first detection and support module 21 inspects the cylindrical batteries. Next, the transport drive module 11 moves the loading transport module 12, the unloading transport module 13 and multiple intermediate transport modules 14 together to the second position. At this time, the second batch of cylindrical batteries is placed on the loading transport module 12, while the first intermediate transport module 14 removes the first batch of cylindrical batteries from the first detection and bearing module 21. Next, the transport drive module 11 moves the loading transport module 12, the unloading transport module 13, and multiple intermediate transport modules 14 together to the first position. At this time, the loading transport module 12 reaches the first detection and support module 21 again. The loading transport module 12 places the second batch of cylindrical batteries on the first detection and support module 21, while the first intermediate transport module 14 transports the first batch of cylindrical batteries to the second detection and support module 21. At this time, the appearance inspection modules arranged at the first and second detection and support modules 21 inspect the cylindrical batteries. Next, the transport drive module 11 moves the loading transport module 12, the unloading transport module 13 and multiple intermediate transport modules 14 together to the second position. At this time, the third batch of cylindrical batteries is placed on the loading transport module 12, while the first intermediate transport module 14 removes the second batch of cylindrical batteries from the first detection and support module 21, and the second intermediate transport module 14 removes the first batch of cylindrical batteries from the second detection and support module 21. Next, the transport drive module 11 moves the loading transport module 12, the unloading transport module 13, and multiple intermediate transport modules 14 together to the first position. At this time, the loading transport module 12 reaches the first detection and support module 21 again. The loading transport module 12 places the third batch of cylindrical batteries on the first detection and support module 21, while the first intermediate transport module 14 transports the second batch of cylindrical batteries to the second detection and support module 21. The second intermediate transport module 14 then transports the first batch of cylindrical batteries to the third detection and support module 21. At this time, the appearance inspection modules correspondingly arranged at the first detection and support module 21, the second detection and support module 21, and the third detection and support module 21 inspect the cylindrical batteries. Next, the transport drive module 11 moves the loading transport module 12, the unloading transport module 13, and multiple intermediate transport modules 14 together to the second position. At this time, the fourth batch of cylindrical batteries is placed on the loading transport module 12, while the first intermediate transport module 14 removes the third batch of cylindrical batteries from the first detection and support module 21, the second intermediate transport module 14 removes the second batch of cylindrical batteries from the second detection and support module 21, and the third intermediate transport module 14 removes the first batch of cylindrical batteries from the third detection and support module 21. Next, the transport drive module 11 moves the loading transport module 12, the unloading transport module 13, and multiple intermediate transport modules 14 together to the first position. At this time, the loading transport module 12 reaches the first detection carrier module 21 again. The loading transport module 12 places the fourth batch of cylindrical batteries on the first detection carrier module 21, while the first intermediate transport module 14 transports the third batch of cylindrical batteries to the second detection carrier module 21. The second intermediate transport module 14 transports the second batch of cylindrical batteries to the third detection carrier module 21. The third intermediate transport module 14 transports the first batch of cylindrical batteries to the NG carrier module 22. At this time, the appearance inspection modules correspondingly arranged at the first detection carrier module 21, the second detection carrier module 21, and the third detection carrier module 21 inspect the cylindrical batteries. Once the first batch of cylindrical batteries is transported to the NG carrier module 22 by the third intermediate transport module 14, the cylindrical batteries that do not meet the appearance requirements can be removed from the NG carrier module 22. Then, the unloading transport module 13 moves the qualified cylindrical batteries away from the NG carrier module 22. Next, the transport drive module 11 moves the loading transport module 12, the unloading transport module 13 and multiple intermediate transport modules 14 together to the first position. At this time, the unloading transport module 13 leaves the NG carrier module 22, and then the cylindrical batteries on the unloading transport module 13 can be removed. Meanwhile, the second batch of cylindrical batteries is transported to the NG carrier module 22 by the third intermediate transport module 14.

[0029] By repeating the above actions, each batch of cylindrical batteries can be sequentially transported to each detection and carrying module 21 for testing. Each time, the transport drive module 11 moves together with the loading transport module 12, the unloading transport module 13, and multiple intermediate transport modules 14, enabling the cylindrical batteries to move to the adjacent battery carrying module 20. This achieves an efficient and rhythmic transport process, and the cylindrical batteries can be tested in a stable posture on the battery carrying module 20 instead of during transport, thus making the testing more accurate.

[0030] Of course, it is also possible to skip designing the NG carrier module 22 and directly cut the material, and discard the cylindrical batteries with appearance problems in other processes.

[0031] Please see Figure 3The specific structures of the loading and unloading transport module 12, the unloading transport module 13, and the multiple intermediate transport modules 14 can be designed according to actual needs. For example, in some optional embodiments, the loading and unloading transport module 12, the unloading transport module 13, and the multiple intermediate transport modules 14 all include a lifting module 15 and a transport seat 16. The lifting module 15 is driven to connect with the transport seat 16 and is used to drive the transport seat 16 to rise and fall. The transport drive module 11 is driven to connect with the lifting module 15. The transport seat 16 is provided with multiple first battery positioning parts 161 for positioning and cooperating with cylindrical batteries. After the lifting module 15 lifts the transport seat 16, it can lift the cylindrical batteries on the battery carrying module 20, realizing the removal of the cylindrical batteries. After the lifting module 15 drives the transport seat 16 to fall, the cylindrical batteries on the transport seat 16 can be placed on the battery carrying module 20. The removal and placement of cylindrical batteries are realized by the rising and falling of the transport seat 16.

[0032] The specific structure of the first battery positioning part 161 can be designed according to actual needs. For example, the first battery positioning part 161 is a positioning groove provided on the top of the transport seat 16.

[0033] The specific structure of the lifting module 15 can be designed according to actual needs. For example, the lifting module 15 can adopt a structure that can achieve translation, such as a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0034] In some optional embodiments, the battery handling assembly 10 includes a handling connector 17. The loading handling module 12, a plurality of intermediate handling modules 14 and the unloading handling module 13 are arranged sequentially on the handling connector 17 along the driving direction of the handling drive module 11. The handling drive module 11 is drivenly connected to the handling connector 17, thereby facilitating the synchronous movement of the loading handling module 12, the unloading handling module 13 and the plurality of intermediate handling modules 14 by the battery handling assembly 10. In this embodiment, the lifting module 15 is disposed on the handling connector 17.

[0035] The specific structure of the transport drive module 11 can be selected according to actual needs. For example, the transport drive module 11 can adopt a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc. In this embodiment, the transport drive module 11 adopts a cylinder translation drive module, and its output end is connected to the transport connector 17. Of course, in other embodiments, the transport drive module 11 may also include a number of translation drive modules corresponding to the loading transport module 12, the unloading transport module 13, and multiple intermediate transport modules 14. Each translation drive module is driven and connected to the loading transport module 12, the unloading transport module 13, and the multiple intermediate transport modules 14, and then drives the loading transport module 12, the unloading transport module 13, and the multiple intermediate transport modules 14 to move synchronously.

[0036] Please see Figure 4 and Figure 5 In some optional embodiments, the battery carrying module 20 includes two carrying plates 23, which are located on both sides of the loading and unloading conveying module 12, the unloading conveying module 13, or the intermediate conveying module 14. That is, when the conveying drive module 11 moves the loading and unloading conveying module 12, the unloading conveying module 13, and the multiple intermediate conveying modules 14 together to the first position, the carrying plates 23 of each battery carrying module 20 are respectively located on both sides of the unloading conveying module 13 and the intermediate conveying module 14. When the conveying drive module 11 moves the loading and unloading conveying module 12, the unloading conveying module 13, and the multiple intermediate conveying modules 14 together to the second position, the carrying plates 23 of each battery carrying module 20 are respectively located on both sides of the loading and unloading conveying module 12 and the intermediate conveying module 14. Multiple second battery positioning parts 231 for positioning and cooperating with cylindrical batteries are provided on one side of the two carrying plates 23 facing each other. The second battery positioning parts 231 are arranged sequentially along the driving direction of the conveying drive module 11. The number of second battery positioning parts 231 matches the number of first battery positioning parts 161. In this embodiment, the transport seat 16 is located between two support plates 23. When the transport seat 16 is lowered, the two ends of the cylindrical battery can be placed on the corresponding second battery positioning parts 231 on the two support plates 23 respectively. When the transport seat 16 is raised, the middle part of the cylindrical battery can be lifted, thereby moving the cylindrical battery away from the second battery positioning parts 231.

[0037] In some alternative embodiments, multiple support rollers 232 are rotatably mounted on two support plates 23 facing each other, and the second battery positioning part 231 is a battery positioning space formed between two adjacent support rollers 232. The support rollers 232 can better support the cylindrical battery, and the rotatable design of the support rollers 232 results in rolling friction between the support rollers 232 and the cylindrical battery, thus reducing friction and protecting the appearance of the cylindrical battery. Furthermore, the outer peripheral surfaces of the two adjacent support rollers 232 are curved, which helps to use the weight of the cylindrical battery to position the cylindrical battery in the exact center of the two adjacent support rollers 232.

[0038] In some optional embodiments, one of the multiple appearance inspection components 30 is a cylindrical surface inspection component 31. Since the cylindrical surface of the cylindrical battery is 360° around the cylindrical battery, the cylindrical battery needs to be rotated during inspection. Therefore, the inspection support module 21 corresponding to the cylindrical surface inspection component 31 needs to add a structure to drive the cylindrical battery to rotate. For this purpose, a battery clamping module 24 is provided on the support plate 23. The battery clamping module 24 includes a movable seat 241 and a telescopic drive module 242. The movable seat 241 is movably disposed on the support plate 23. Multiple clamping members 243 are rotatably disposed on the movable seat 241. The clamping members 243 are located on the side of the second battery positioning part 231. The telescopic drive module 242 is drivenly connected to the movable seat 241 and is used to drive the movable seat 241 toward or away from the second battery positioning part 231. One of the battery clamping modules 24 of the support plate 23 also includes a rotation drive module 244, which is drivenly connected to the clamping members 243. The telescopic drive module 242 drives the movable seat 241 to move toward the second battery positioning part 231, thereby causing the clamping member 243 to press against the end of the cylindrical battery. The clamping members 243 on the two support seats cooperate to press the two ends of the cylindrical battery, thereby clamping the cylindrical battery. The rotation drive module 244 drives the clamping member 243 on one of the movable seats 241 to rotate, thereby driving the cylindrical battery to rotate through friction, so that different positions of the cylindrical surface of the cylindrical battery can be detected by the cylindrical surface detection component 31.

[0039] The specific structure of the telescopic drive module 242 can be selected according to the actual needs. For example, the detection translation drive module 40 can be a screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module, etc.

[0040] The specific structure of the battery clamping module 24 can be selected according to actual needs. For example, the battery clamping module 24 includes a battery rotation drive motor, multiple first gears and multiple second gears. The first gears are connected to the clamping member 243, and the second gears mesh with two adjacent first gears. The battery rotation drive motor is driven by one of the first gears or one of the second gears. This example is not limited to this one.

[0041] In some optional embodiments, the detection device of the cylindrical battery detection equipment further includes a detection translation drive module 40, which is drivenly connected to multiple battery carrier modules 20. The appearance detection component 30 includes multiple detection modules 34 for acquiring detection images of the cylindrical battery. The multiple detection modules 34 are arranged sequentially around the battery carrier modules 20 along the driving direction of the detection translation drive module 40. Since the detection module 34 typically uses a camera, to improve the accuracy of image acquisition, it is preferable that the detection module 34 typically acquires an image of a single cylindrical battery at a time. However, to improve handling efficiency, a large number of cylindrical batteries are handled each time. But it would be too costly to arrange a detection module 34 for each cylindrical battery. Therefore, considering both improving detection and handling efficiency, multiple detection modules 34 are designed, but their number does not exceed the number of cylindrical batteries in a single batch. For example, if a batch of cylindrical batteries contains twenty-four, there are four detection modules 34. Each time, the four detection modules 34 acquire images of four cylindrical batteries. Then, the detection translation drive module 40 moves the battery carrying module 20 by a distance equal to the distance between adjacent cylindrical batteries. Then, the four detection modules 34 can acquire images of another four cylindrical batteries. The detection translation drive module 40 only needs to move the battery carrying module 20 five times for the four detection modules 34 to acquire images of twenty-four cylindrical batteries. This reduces the number of detection modules 34 and increases the detection speed. Of course, the number of cylindrical batteries in the same batch and the number of detection modules 34 can be designed according to actual needs, and this example is not the only one.

[0042] The specific structure of the detection translation drive module 40 can be selected according to actual needs. For example, the detection translation drive module 40 can be a lead screw drive module, a rotary motor translation drive module, a belt translation drive module, a cylinder translation drive module, or a linear motor translation drive module. In this embodiment, the support plates 23 of adjacent battery carrier modules 20 are connected by connecting rods 25. The detection translation drive module 40 adopts a linear motor translation drive module and is connected to the support plate 23 of one of the battery carrier modules 20. The two support plates 23 of the same battery carrier module 20 are connected together. In this way, the detection translation drive module 40 only needs to drive one support plate 23 to move, which can drive all battery carrier modules 20 to move together. After each appearance detection component 30 is detected, the detection translation drive module 40 synchronously drives all battery carrier modules 20 to move together, and then other cylindrical batteries are detected. This helps to speed up the detection efficiency and facilitates operation.

[0043] In addition, the structure of the detection module 34 can also be designed according to actual needs. The structure of the detection module 34 and the principle of judging whether there are appearance defects in the cylindrical battery by detecting the image are well known to those skilled in the art, and will not be described in detail here.

[0044] It should be noted that the detection module 34 of the cylindrical surface detection component 31, the detection module 34 of the end face 2D detection component 32, and the detection module 34 of the end face 3D detection component 33 may have the same or different structures. Their structures and detection principles are well known to those skilled in the art and will not be described in detail here.

[0045] The detection device of the cylindrical battery testing equipment described above can be applied to the cylindrical battery testing equipment, which includes: the detection device of the cylindrical battery testing equipment described above.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
