[0040] Reference Figures 1 to 5 , shows a structural schematic diagram of a battery pack detection device described in an embodiment of the present application, which may specifically include: a ceiling rail module 10, a data detection module and a guide vehicle 20; the ceiling rail module 10 includes a ceiling rail frame and a clamping structure 11, and the clamping structure 11 is movably connected to the ceiling rail frame; the data detection module is arranged in the ceiling rail frame, and at least part of the data detection module is connected to the ceiling rail frame; the guide vehicle 20 is used to tow the battery pack to move; the guide vehicle 20 tows the battery pack to a preset position in the ceiling rail frame, and the clamping structure 11 clamps the battery pack to the detection area of ​​the data detection module, so that the data detection module detects the parameters of the battery pack, wherein the parameters include at least one of size, shape and weight.

[0041] In the embodiment of the present application, the battery pack is towed and moved by the guide vehicle 20 so that the battery pack is in the preset position in the overhead rail frame, and the battery pack is clamped and moved by the clamping mechanism, and the height position and horizontal position of the battery pack can be adjusted, so as to move the battery pack to the detection area of ​​the data detection module, so that the data detection module can automatically detect various data of the battery pack, such as size, shape, and weight, etc., which reduces the dependence on manual labor, avoids manual errors such as misjudgment, improves the accuracy of data measurement, and improves work efficiency. There is no need to manually measure the size of the battery pack with a caliper, nor is there any need to manually judge the shape of the battery pack, nor is there any need to manually operate the overhead crane and other structures to detect the weight of the battery pack, which saves time and effort and improves production efficiency.

[0042] Specifically, in the embodiment of the present application, the guide vehicle 20 is also an AGV (Automated Guided Vehicle), which can automatically travel along a predetermined route to automatically transport the battery pack from the starting point of the online inspection to the end point of the offline inspection. In actual applications, the travel path of the guide vehicle 20 can be flexibly changed according to actual needs to realize the automation of the entire process of battery pack inspection.

[0043] In the embodiment of the present application, for example, the overhead rail frame can be a four-axis overhead rail to achieve a relatively stable and reliable movement effect for the clamping mechanism and the battery pack. The guide rail 13 clamping mechanism is movably connected to the overhead rail frame. Specifically, the clamping mechanism may include a connecting beam 31, a connecting arm, and a clamping claw. The connecting beam 31 may be slidably connected to the overhead rail frame, the connecting arm is connected to the connecting beam 31, and the connecting arm may perform telescopic movement relative to the connecting beam 31. The clamping claw is connected to one end of the connecting arm away from the connecting beam 31, and the clamping claw may be extended to clamp or release the battery pack.

[0044] Specifically, the connecting beam 31 can be connected to the overhead rail frame by sliding in the horizontal direction. The sliding of the connecting beam 31 in the horizontal direction can drive the battery pack clamped by the clamp to move in the horizontal direction to adjust the horizontal position of the battery pack. The connecting arm can be extended and retracted in the vertical direction. The battery pack clamped by the clamp can be moved in the vertical direction by extending and retracting the connecting arm in the vertical direction to adjust the vertical position, i.e., the height position, of the battery pack. The clamp can be extended and retracted in the horizontal direction. When the clamp is located at the periphery of the battery pack and positioned with the battery pack, the clamp can be retracted in the horizontal direction to clamp the battery pack. After the battery pack is clamped and moved to a preset position, the clamp can be opened in the horizontal direction to release the clamping of the battery pack.

[0045] In the embodiment of the present application, for example, the preset position in the overhead rail frame can be a position corresponding to the clamping structure 11, and the preset position can also be a position corresponding to the data detection module, which can be set according to actual needs. The embodiment of the present application does not limit the specific position of the preset position.

[0046] Optionally, in the embodiment of the present application, the data detection module includes an appearance detection component 30, the overhead rail frame includes a support 12 and a guide rail 13 connected to the support 12; the appearance detection component 30 is movably connected to the guide rail 13, the clamping structure 11 clamps the battery pack and moves it to the detection area of ​​the appearance detection component 30, and the appearance detection component 30 detects at least one of the shape and size of the battery pack. In this way, the appearance detection component 30 is movably connected to the guide rail 13, so that the appearance detection component 30 can be moved relative to the guide rail 13. Specifically, the appearance detection component 30 can be slidably connected to the guide rail 13 to adjust the relative position between the appearance detection component 30 and the battery pack, so that the appearance detection component 30 and the battery pack have a better alignment effect, thereby improving the accuracy of the detection.

[0047] In the embodiment of the present application, optionally, the shape detection component 30 includes a connecting beam 31, a first shooting module 32 and a second shooting module 33, the connecting beam 31 is slidably connected to the guide rail 13, and the first shooting module 32 and the second shooting module 33 are respectively connected to the connecting beam 31; the clamping structure 11 clamps the battery pack and moves it to the shooting area of ​​the first shooting module 32 and the second shooting module 33, the first shooting module 32 shoots and detects the size of the battery pack, and the second shooting module 33 shoots and detects the contour of the battery pack. In this way, the relative position between the first shooting module 32 and the second shooting module 33 and the battery pack can be adjusted by sliding the connecting beam 31 relative to the guide rail 13. Then, the size of the battery pack is photographed and detected by the first shooting module 32 to obtain the size data of the battery pack, and the shape of the battery pack is photographed and detected by the second shooting module 33 to obtain the shape contour data of the battery pack, so as to determine whether the battery pack is deformed and whether it meets the shape requirements.

[0048] For example, in the embodiment of the present application, the first shooting module 32 can be a 2D camera, which can be used to shoot and detect the size of the battery pack to obtain the size data of the battery pack. Specifically, the battery pack is provided with a hoisting hole, and the 2D camera can be used to shoot and detect the size of the hoisting hole of the battery pack to determine whether the hoisting size of the battery pack meets the quality inspection requirements. The second shooting module 33 can be a 3D camera, which can be used to shoot and detect the shape and contour of the battery pack to determine whether the shape of the battery pack is deformed and whether it meets the factory shape and contour requirements.

[0049] Specifically, in the embodiment of the present application, the connecting beam 31 may be a three-axis structure, including a first cross beam, a second cross beam and a first longitudinal beam, wherein the first cross beam and the second cross beam are arranged at intervals, the first longitudinal beam is arranged between the first cross beam and the second cross beam, and the first longitudinal beam is slidably connected to the first cross beam and the second cross beam, respectively, and the first shooting module 32 and the second shooting module 33 are connected to the first longitudinal beam, respectively. The first cross beam and the second cross beam may be connected to the guide rail 13 of the overhead rail frame, respectively, and the first longitudinal beam may be moved in the horizontal direction relative to the first cross beam and the second cross beam, so as to adjust the position of the first shooting module 32 and the second shooting module 33 in the horizontal direction with respect to the battery pack, thereby improving the accuracy of the appearance detection of the battery pack.

Thus, the sliding of the connecting member in the vertical direction may drive the first camera module 32 and the second camera module 33 to slide in the vertical direction, so as to adjust the position of the first camera module 32 and the second camera module 33 in the vertical direction with respect to the battery pack, thereby improving the accuracy of the shape detection of the battery pack.

[0051] Optionally, in the embodiment of the present application, the data detection module further includes a weight detection component 40, which is disposed in the overhead rail frame; the clamping structure 11 clamps the battery pack and moves it to the weight detection component 40, so that the weight detection component 40 performs weight detection on the battery pack. In this way, the battery pack is clamped and transported to the weight detection component 40 by the clamping mechanism, and then the clamping of the battery pack by the sticking mechanism is released, so that the battery pack is located on the weight detection component 40, and the weight of the battery pack is detected by the weight detection component 40 to obtain the weight data of the battery pack.

[0052] In some optional embodiments of the present application, the weight detection assembly 40 includes a bracket 41, a fixing member 42 and a weighing device 43; the weighing device 43 is movably connected to the bracket 41, the fixing member 42 is connected to the bracket 41, and the fixing member 42 is movably connected to the weighing device 43 to fix the weighing device 43. In this way, the bracket 41 provides a relatively stable and reliable support for the weighing device 43. When the battery pack is placed on the weighing device 43, the fixing member 42 can be connected to the weighing device 43, for example, the fixing member 42 can be clamped on the edge of the weighing device 43. The fixing member 42 makes the weighing device 43 stably connected to the bracket 41, so as to avoid the weighing device 43 from easily shaking left and right, etc., which affects the accuracy of the weight detection of the battery pack. For example, in the embodiment of the present application, the weighing device 43 can be a floor scale, an electronic scale, etc., and the weighing device 43 can be a frame structure, which has a good bearing effect on the battery pack while reducing the material consumption. The embodiment of the present application does not limit the specific type and structure of the weighing device 43.

[0053] Optionally, in the embodiment of the present application, the battery pack detection device further includes a third camera module 44, the third camera module 44 is slidably connected to the weight detection assembly 40, the battery pack includes a bottom guard plate, and the third camera module 44 is used to take a photo and record the bottom guard plate. In this way, while the weight of the battery pack is being detected, the bottom guard plate of the battery pack can also be photographed and recorded by the third camera module 44, thereby realizing the recording of the bottom guard plate of the battery pack.

[0054] In the embodiment of the present application, optionally, the battery pack detection device further includes a lifting structure 50 and a tooling vehicle 21, the lifting structure 50 is arranged in the overhead rail frame, and the tooling vehicle 21 is used to carry the battery pack; the guide vehicle 20 pulls the tooling vehicle 21 to move to a preset position in the overhead rail frame, the lifting structure 50 moves the tooling vehicle 21 to a preset height, and the clamping structure 11 clamps the battery pack for movement. In this way, the battery pack is carried more stably and reliably by the tooling vehicle 21, so that the battery pack has better stability, and the battery pack is also prevented from easily causing friction and other effects on its electrical performance. In addition, the tooling vehicle 21 is raised and lowered by the lifting structure 50, thereby achieving the lifting and lowering of the battery pack, without the need for the lifting structure 50 to directly contact the battery pack. For example, a shooting and positioning structure may be provided on the lifting structure 50, so that a more accurate position of the tooling vehicle 21 can be obtained by shooting and positioning structure, thereby improving the displacement accuracy of the battery pack.

[0055] Optionally, in the embodiment of the present application, the battery pack detection device further includes a shooting frame 51, and the shooting frame 51 is connected to the jacking structure 50; a fourth shooting module 52 is provided around the shooting frame 51, and the fourth shooting module 52 is used to shoot and record the side of the battery pack. In this way, while the tooling vehicle 21 carrying the battery pack is lifted by the jacking structure 50, the shape and size of the side of the battery pack can also be shot and recorded by the fourth shooting module 52 on the shooting frame 51. For example, the battery pack is usually a hexahedral structure, and the side of the battery pack refers to the four side structures of the battery pack.

[0056] For example, in an embodiment of the present application, the fourth shooting module 52 can be a camera, the number of the fourth shooting modules 52 can be 4, which are respectively arranged around the shooting frame 51, the number of the fourth shooting modules 52 can be 8, and 2 fourth shooting modules 52 are respectively arranged on each side of the shooting frame 51, and so on. The embodiment of the present application may not limit the specific number and setting method of the fourth shooting module 52.

[0057] In some optional embodiments of the present application, the battery pack detection device further includes a code scanning module, the code scanning module is connected to the jacking structure 50, the battery pack is provided with a label, and the code scanning module is used to scan and record the label. In this way, after the tooling vehicle 21 carrying the battery pack is lifted by the jacking structure 50, the label of the battery pack can be automatically scanned and detected by the code scanning module to obtain the label information of the battery pack. By way of example, the label can be a barcode, a QR code, etc., and the specific type of the label may not be limited in the embodiments of the present application.

[0058] Optionally, in an embodiment of the present application, the battery pack detection device further includes a fifth shooting module 15, the fifth shooting module 15 is connected to the overhead rail module 10, the battery pack includes an upper cover, and the fifth shooting module 15 is used to shoot and record the upper cover. In this way, the fifth shooting module can be used to obtain information such as the shape and size of the upper cover of the battery pack and keep a record. Specifically, the fifth shooting module 15 can be set at the top of the overhead rail frame so that the fifth shooting module 15 has a better shooting effect on the upper cover of the battery pack.

[0059] In an embodiment of the present application, optionally, the battery pack detection device further includes a controller 60, and the controller 60 is electrically connected to the overhead rail module 10, the data detection module, and the guide vehicle 20, respectively. In this way, by setting logical operations in the controller 60, the controller 60 controls the movement operation of the overhead rail module 10, the detection operation of the data detection module, and the traction operation of the guide vehicle 20, etc., with higher control accuracy. By way of example, the controller 60 can be a control cabinet, a control panel, etc., and the specific type of the controller 60 may not be limited in the embodiment of the present application. The controller 60 may be connected to the overhead rail module 10, or may be connected to the jacking structure 50, etc., and the specific setting position of the controller may not be limited in the embodiment of the present application.

[0060] For example, in the embodiment of the present application, the complete operation process of the battery pack detection device can be: the guide vehicle 20 first pulls the tooling vehicle 21 carrying the battery pack to move, and then the lifting structure 50 accurately positions and lifts the tooling vehicle 21 through the positioning structure, and then the shooting frame 51 on the lifting structure 50 takes pictures of the four sides of the battery pack through the fourth shooting module 52. Furthermore, the clamping mechanism of the overhead rail module 10 can position the battery pack through a camera, etc. After the clamping mechanism adjusts and corrects the clamping claws according to the positioning data, the clamping claws of the clamping mechanism clamp and grab the battery pack, and shift the battery pack to a position relative to the third shooting module 44, and take pictures of the bottom guard plate of the battery pack for record.

[0061] Next, the overhead rail frame moves the battery pack to the weight detection assembly 40 through the guide rail 13. After the clamping mechanism places the battery pack on the platform of the weighing device 43, the clamping mechanism moves to avoid the battery pack, and then the fifth camera module 15 on the weight detection assembly 40 takes a photo of the upper cover of the battery pack for record. Specifically, after the battery pack is placed on the platform of the weighing device 43, the fixing member 42 is connected to the edge of the frame of the weighing device 43 to fix and guide the weighing device 43, so that the weighing device 43 is relatively stable. Then, the weighing device 43 automatically weighs to obtain the weight data of the battery pack.

[0062] Then, the shape detection component 30 moves the first shooting module 32 and the second shooting module 33 by moving the connecting beam 31, so that the first shooting module 32 performs size shooting detection on the lifting holes of the battery pack, and the second shooting module performs 3D contour scanning on the battery pack, thereby realizing shape shooting detection of the battery pack.

[0063] The weight detection of the battery pack by the weight detection component 40 can be performed simultaneously with the step of detecting the size and shape of the battery pack by the shape detection component 30. After the weight detection step is completed, the third camera module 44 can slide relative to the weight detection component 40 so that the third camera module 44 can take a picture of the bottom guard plate of the battery pack.

[0064] Finally, after the weight detection assembly 40 and the shape detection assembly 30 are completed, the clamping mechanism can clamp and grab the battery pack and move it toward the jacking structure 50, and then place the battery pack on the load table of the tooling vehicle 21 on the jacking structure 50. After the battery pack is placed on the tooling vehicle 21, the controller 60 controls the jacking structure 50 to descend, and controls the guide vehicle 20 to pull the tooling vehicle 21 away with the battery pack, completing the inspection of the battery pack and taking the battery pack offline.
