The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The detection device 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0032] Reference Figure 1-Figure 2According to the detection device 100 of the embodiment of the utility model, the detection device 100 is used to detect the shell. For example, the detection device 100 can be used for the battery shell. The detection device 100 includes a frame 10, a positioning component 20 and a detection assembly 30. The positioning component 20 is arranged on the frame 10 and is used to position the shell. The detection assembly 30 is arranged on the frame 10 and is used to detect the inner cavity size and / or the outer size of the shell. By setting the frame 10, the positioning component 20 and the detection component are all arranged on the frame 10. The frame 10 can support the positioning component 20 and the detection component, and at the same time, it can improve the overall structural strength of the detection device 100. By setting the positioning component 20, the positioning component 20 is used to position the shell, which can ensure the stability and reliability of the shell position, and can reduce or avoid the situation where the shell position is unstable during the detection process, resulting in inaccurate detection results.

[0033] The detection component 30 is used to detect the inner cavity size and / or outer size of the shell. For example, the detection component 30 can be used to detect the inner cavity size of the shell; for example, the detection component 30 can be used to detect the outer size of the shell; for another example, the detection component 30 can be used to detect the inner cavity size and outer size of the shell.

[0034] The detection component 30 is movable between a detection position and a non-detection position. When the detection component 30 is in the detection position, the detection component 30 is suitable for cooperating with the shell to detect the inner cavity size and / or outer size of the shell. When the detection component 30 is in the non-detection position, the detection component 30 is suitable for disengaging from the shell. When the shell needs to be inspected, the shell is fixed to the positioning component 20, and the detection component 30 moves to the detection position and cooperates with the shell, so that the inner cavity size and / or outer size of the shell can be detected; after the detection is completed, the detection component 30 moves to the non-detection position. Among them, when the detection component 30 is in the non-detection position, it is convenient to install, disassemble and debug the shell and the positioning component 20.

[0035] In addition, by setting up the detection component 30, the detection component 30 can cooperate with the shell to detect the inner cavity size and / or outer size of the shell. Compared with manual detection, using the detection device 100 to detect the size of the shell can save time and effort and improve detection efficiency.

[0036] The detection device 100 of the embodiment of the present utility model can be used to detect the size of a shell, and the shell includes but is not limited to a battery shell.

[0037] According to the detection device 100 of the embodiment of the utility model, the detection device 100 is provided with a detection component 30, and the detection component 30 can cooperate with the shell to detect the inner cavity size and / or outer size of the shell. Compared with manual detection, using the detection device 100 to perform size detection on the shell can save time and labor and improve detection efficiency.

[0038] Reference Figure 3-Figure 4 According to some embodiments of the present invention, the detection assembly 30 includes an inner detection rod 31, the inner detection rod 31 includes an inner detection rod body 32 and a first rangefinder 33, one end of the inner detection rod body 32 adjacent to the positioning component 20 is a first detection end 321, and the first rangefinder 33 is arranged at the first detection end 321. In the detection position, the first rangefinder 33 is located in the shell and is used to detect the inner cavity size of the shell, and in the non-detection position, the inner detection rod 31 is completely located outside the shell. By setting the inner detection rod 31, when it is necessary to detect the inner cavity size of the shell, the detection assembly 30 moves to the detection position, the shell is fixed to the positioning component 20, the first rangefinder 33 of the inner detection rod 31 is located in the shell, and the first rangefinder 33 can detect the inner cavity size of the shell; when the detection assembly 30 moves to the non-detection position, the inner detection rod 31 is completely located outside the shell, which can avoid interference between the shell and the inner detection rod 31 during installation, disassembly and debugging.

[0039] Optionally, the first rangefinder 33 may use laser ranging, which can detect the inner cavity size of the shell relatively quickly with high detection accuracy and reliability. At the same time, the use of laser ranging can avoid direct contact between the first rangefinder 33 and the shell, which can reduce or avoid the first rangefinder 33 or the shell being damaged due to the first rangefinder 33 touching the shell during the measurement process.

[0040] Optionally, the first detection end 321 may be provided with a plurality of first range finders 33. For example, referring to Figure 3 , two first rangefinders 33 can be set at the first detection end 321, and the two first rangefinders 33 are symmetrically arranged on opposite sides of the first detection end 321. When the detection component 30 is located at the detection position, the distance between the two first rangefinders 33 is L1, one of the first rangefinders 33 can detect the distance L2 from the inner wall of the shell to the first rangefinder 33, and the other first rangefinder 33 can detect the distance L3 from the inner wall of the shell to the first rangefinder 33. When the shell is at this position, the size L4 of the inner cavity of the shell in the set direction (for example, the set direction may include the left and right direction) is L1+L2+L3, so that the inner cavity size of the shell can be detected by the inner detection rod 31.

[0041] It should be noted that the “plurality” in the present invention refers to two or more than two.

By setting the outer detection rod 34, when it is necessary to detect the outer dimensions of the shell, the detection assembly 30 moves to the detection position, the shell is fixed to the positioning component 20, the second rangefinder 36 of the outer detection rod 34 is located outside the shell and opposite to the outer circumference of the shell, and the second rangefinder 36 can detect the outer dimensions of the shell; when the detection assembly 30 moves to the non-detection position, the outer detection rod 34 is staggered from the outer circumference of the shell, which can avoid interference between the shell and the outer detection rod 34 during installation, disassembly and debugging.

[0043] Optionally, the second rangefinder 36 can use laser ranging. Laser ranging can detect the inner cavity size of the shell relatively quickly, and the detection accuracy and reliability are high. At the same time, the use of laser ranging can avoid direct contact between the second rangefinder 36 and the shell, which can reduce or avoid the second rangefinder 36 or the shell being damaged due to the second rangefinder 36 touching the shell during the measurement process.

[0044] Optionally, the number of the external detection rods 34 may be multiple, and the second detection end 351 of each external detection rod is provided with a second rangefinder 36. Figure 5-Figure 6 There are two outer detection rods 34, which are respectively located on opposite sides of the shell. The second detection end 351 of each outer detection rod 34 is respectively provided with a second rangefinder 36. When the detection assembly 30 is located at the detection position, the distance between the two second rangefinders 36 is L5, one of the second rangefinders 36 can detect the distance L6 from the outer wall of the shell to the second rangefinder 36, and the other second rangefinder 36 can detect the distance L7 from the outer wall of the shell to the second detector. When the shell is at this position, the size L8 of the outer wall of the shell in the set direction (for example, the set direction can be the left and right direction) is L5-L6-L7, so that the outer dimensions of the shell can be detected by using the outer detection rods 34.

[0045] Reference Figure 3-Figure 6According to some embodiments of the present invention, the detection assembly 30 includes an inner detection rod 31, the inner detection rod 31 includes an inner detection rod body 32 and a first rangefinder 33, one end of the inner detection rod body 32 adjacent to the positioning component 20 is a first detection end 321, the first rangefinder 33 is arranged at the first detection end 321, in the detection position the first rangefinder 33 is located in the shell and is used to detect the inner cavity size of the shell, in the non-detection position the inner detection rod 31 is completely located outside the shell. By setting the inner detection rod 31 and the outer detection rod 34, when the detection component 30 is in the detection position, the first rangefinder 33 of the inner detection rod 31 is located inside the shell, and the second rangefinder 36 of the outer detection rod 34 is located outside the shell and opposite to the outer circumferential surface of the shell, the inner detection rod 31 and the outer detection rod 34 can detect the inner cavity size and the outer size of the shell; when the detection component 30 is in the non-detection position, the inner detection rod 31 is completely outside the shell, and the outer detection rod 34 is staggered from the outer circumferential surface of the shell, which can avoid interference between the shell and the inner detection rod 31 and the outer detection rod 34 during installation, disassembly and debugging.

[0046] Furthermore, the detection component 30 also includes an ultrasonic flaw detection component 40, which includes an ultrasonic probe 41 and an ultrasonic receiver 42 that are arranged relative to and at intervals. The ultrasonic probe 41 is arranged on the inner detection rod body 32, and the ultrasonic receiver 42 is arranged on the outer detection rod body 35.

In the detection position, the ultrasonic probe 41 is located inside the shell, and the ultrasonic receiver 42 is opposite to the outer peripheral surface of the shell. The ultrasonic probe 41 can emit ultrasonic waves inside the shell, and the ultrasonic waves can be received by the ultrasonic receiver 42 opposite to the outer peripheral surface of the shell after passing through the shell. When there are defects such as cracks or holes inside the shell, the signal received by the ultrasonic receiver 42 will change. By setting up the ultrasonic flaw detection component 40, it is possible to quickly and accurately detect whether there are defects such as cracks or holes inside the shell, and the location of defects such as cracks or holes can be quickly determined, so that subsequent maintenance and other related operations on the shell can be facilitated.

[0047] Reference Figure 1-Figure 3 According to some embodiments of the present invention, the positioning component 20 includes a positioning mechanism, a first driving mechanism and a second driving mechanism. The positioning mechanism includes a positioning disk 22 and a plurality of claws 23. The plurality of claws 23 are arranged at intervals along the circumference of the positioning disk 22. For example, referring to Figure 2-Figure 3The positioning mechanism includes a positioning disk 22 and three claws 23, the three claws 23 are arranged at intervals along the circumference of the positioning disk 22, and the plurality of claws 23 are movably disposed on the positioning disk 22 and used to clamp the housing, for example, the claws 23 can move along the radial direction of the positioning disk 22. The first driving mechanism is disposed on the positioning disk 22 and connected to the plurality of claws 23 to drive the claws 23 to move, the second driving mechanism is disposed on the frame 10 and connected to the positioning disk 22, and the second driving mechanism is used to drive the positioning disk 22 to move, for example, the second driving mechanism is used to drive the positioning disk 22 to move or rotate around the central axis of the positioning disk 22.

[0048] When the shell needs to be positioned, the shell can be placed on the positioning disk 22, and the first driving mechanism can drive the multiple claws 23 to move along the radial direction of the positioning disk 22 toward the shell and clamp the shell. The multiple claws 23 clamping the shell can ensure the stability of the shell position, and thus ensure the accuracy of the detection of the detection component 30; after the shell is detected, the first driving mechanism can drive the multiple claws 23 to move along the radial direction of the positioning disk 22 toward the direction away from the shell, so that the shell is disengaged from the multiple claws 23. At this time, the shell can be taken out from the positioning disk 22.

[0049] In addition, the second driving mechanism can drive the positioning plate 22 to move or rotate around the central axis of the positioning plate 22, so that the detection component 30 can perform multi-position and multi-angle detection on the housing, thereby improving the accuracy of the detection.

[0050] Optionally, the second driving mechanism can drive the positioning plate 22 to move. For example, the second driving mechanism can drive the positioning plate 22 to move in the front-to-back direction, and the detection component 30 includes an inner detection rod 31, and the inner detection rod 31 includes an inner detection rod body 32 and two first rangefinders 33, and the two first rangefinders 33 are symmetrically arranged in the left-right direction, and the shell is a square shell. When the detection component 30 is in the detection position, the two first detectors are located in the shell and can measure the size of the shell cavity in the left-right direction. The second driving mechanism can drive the positioning plate 22 to move in the front-to-back direction, thereby being able to drive the shell located on the positioning plate 22 to move in the front-to-back direction, so that the two first detectors can detect the size of multiple parts of the shell cavity in the left-to-right direction, which can improve the accuracy of the detection.

[0051] For another example, the second driving mechanism can drive the positioning plate 22 to move in the front-to-back direction, the detection component 30 includes an outer detection rod 34, the outer detection rod 34 includes an outer detection rod body 35 and a second rangefinder 36, the number of the outer detection rods 34 is two and the two outer detection rods 34 are respectively located on the left and right sides of the positioning component 20, and the second detection end 351 of each outer detection rod 34 is respectively provided with a second rangefinder 36, and the shell is a square shell. When the detection component 30 is located at the detection position, the two second detectors are located outside the shell and opposite to the outer peripheral surface of the shell, and can measure the size of the outer wall of the shell in the left-right direction. The second driving mechanism can drive the positioning plate 22 to move in the front-to-back direction, thereby being able to drive the shell located on the positioning plate 22 to move in the front-to-back direction, so that the two second detectors can detect the size of multiple parts of the outer wall of the shell in the left-right direction, which can improve the accuracy of the detection.

[0052] Optionally, the second drive mechanism can drive the positioning plate 22 to rotate around the central axis of the positioning plate 22, and can detect the shell at multiple angles. For example, the detection assembly 30 includes an outer detection rod 35, an inner detection rod 32, and an ultrasonic flaw detection assembly 40, and the ultrasonic flaw detection assembly 40 includes an ultrasonic probe 41 and an ultrasonic receiver 42 that are relatively and spaced apart.

In the detection position, the ultrasonic probe 41 is located inside the shell, and the ultrasonic receiver 42 is opposite to the outer peripheral surface of the shell. The ultrasonic probe 41 can emit ultrasonic waves inside the shell, and the ultrasonic waves can be received by the ultrasonic receiver 42 opposite to the outer peripheral surface of the shell after passing through the shell, so that the inside of the shell can be detected. The second drive mechanism can drive the positioning plate 22 to rotate around the central axis of the positioning plate 22, and can make the shell rotate around the central axis of the positioning plate 22, so that the inside of the shell can be detected at multiple angles.

The second driving mechanism is disposed on the frame 10 and is connected to the positioning disk 22. The second driving mechanism is used to drive the positioning disk 22 to move. The second driving mechanism is used to drive the positioning disk 22 to move or rotate around the central axis of the positioning disk 22.

[0055] The positioning component 20 is an electric chuck 21, which can quickly clamp and position the shell, and the positioning is relatively accurate, which can ensure the stability and reliability of the shell position. At the same time, the electric chuck 21 has high versatility and can position shells of different shapes and sizes. In addition, the second driving mechanism can drive the positioning plate 22 to move or rotate around the central axis of the positioning plate 22, so that the detection component 30 can perform multi-position and multi-angle detection on the shell, thereby improving the accuracy of the detection.

The motor shaft 511 of the driving motor 51 rotates, driving the transmission gear 52 connected to the motor shaft 511 to move, thereby driving the transmission rack 53 meshed with the transmission gear 52 to move, thereby driving the detection assembly 30 to move. In addition, the transmission rack 53 extends in the up-down direction. When the transmission gear 52 drives the transmission rack 53 to move, the transmission rack 53 can move in the up-down direction, thereby driving the detection assembly 30 to move in the up-down direction.

[0060] Optionally, the number of the driving motors 51 can be multiple, and the multiple motors drive the detection component 30 to move simultaneously. Figure 3-Figure 4 There are two drive motors 51, two transmission gears 52 and they are respectively connected to the motor shafts 511 of the drive motors 51, the left and right sides of the transmission rack 53 are respectively engaged with the two transmission gears 52, and the two drive motors 51 drive the detection component 30 to move simultaneously.

[0061] Reference Figure 1-Figure 6 According to some embodiments of the utility model, the detection assembly 30 includes a connecting plate 14, an inner detection rod 31 and an outer detection rod 34, the inner detection rod 31 and the outer detection rod 34 are both connected to the connecting plate 14, the inner detection rod 31 includes an inner detection rod body 32 and a first rangefinder 33, the inner detection rod body 32 extends in the up-down direction, the upper end of the inner detection rod 31 is connected to the connecting plate 14, the lower end of the inner detection rod body 32 is a first detection end 321, the first rangefinder 33 is arranged at the first detection end 321, the outer detection rod 34 includes an outer detection rod body 35 and a second rangefinder 36, the outer detection rod body 35 extends in the up-down direction, the upper end of the outer detection rod 34 is connected to the connecting plate 14, the lower end of the outer detection rod body 35 is a second detection end 351, the second rangefinder 36 is arranged at the second detection end 351, the inner detection rod body 32 and the outer detection rod body 35 are both movably arranged in the up-down direction on the fixed plate 13.

[0062] By setting the connecting plate 14, the upper end of the inner detection rod 31 and the upper end of the outer detection rod 34 are both connected to the connecting plate 14. When the shell needs to be inspected, the driving component 50 drives the detection component 30 to move downward to the detection position. During this process, the connecting plate 14 can make the inner detection rod 31 and the outer detection rod 34 move synchronously, so that the detection component 30 can simultaneously detect the inner cavity size and the outer size of the shell, which can greatly improve the detection efficiency.

[0063] After the detection is completed, the driving component 50 drives the detection component 30 to move upward to the non-detection position. During this process, the connecting plate 14 can make the inner detection rod 31 and the outer detection rod 34 move synchronously, so that the inner detection rod 31 and the outer detection rod 34 can be disengaged from the shell at the same time, which can simplify the operation process and facilitate operation.

[0064] Among them, in the detection position, the first rangefinder 33 is located in the shell and is used to detect the inner cavity size of the shell, and the second rangefinder 36 is opposite to the outer circumference of the shell and is used to detect the outer size of the shell. The inner cavity size and the outer size of the shell can be detected simultaneously and quickly, thereby improving the detection efficiency and the convenience of detection; in the non-detection position, the inner detection rod 31 is completely outside the shell, and the outer detection rod 34 is staggered from the outer circumference of the shell. The inner detection rod 31 and the outer detection rod 34 can be disengaged from the shell at the same time, which can simplify the operation process and facilitate operation.

[0065] Reference Figure 1-Figure 6 According to some embodiments of the present utility model, the driving assembly 50 includes a driving motor 51, a transmission rack 53 and a transmission gear 52. The transmission gear 52 is connected to the motor shaft 511 of the driving motor 51. The transmission rack 53 extends in the up-down direction and meshes with the transmission gear 52. The transmission rack 53 is arranged on the inner detection rod body 32 and is located above the first rangefinder 33. The motor shaft 511 of the driving motor 51 rotates, driving the transmission gear 52 connected to the motor shaft 511 to move. The transmission gear 52 drives the transmission rack 53 meshed with the transmission gear 52 to move. The transmission rack 53 is arranged on the inner detection rod 31. The inner detection rod 31 moves with the transmission rack 53 and drives the connecting plate 14 to move. The connecting plate 14 drives the outer detection rod 34 connected thereto to move.

[0066] When it is necessary to inspect the shell, the shell is fixed to the positioning component 20, and the motor shaft 511 of the driving motor 51 rotates, driving the transmission gear 52 connected to the motor shaft 511 to move, and the transmission gear 52 drives the inner detection rod 31 to move downward, so that the first rangefinder 33 of the inner detection rod 31 moves to the inside of the shell. At the same time, the inner detection rod 31 drives the outer detection rod 34 which is also connected to the connecting plate 14 to move synchronously through the connecting plate 14, so that the second rangefinder 36 of the outer detection rod 34 moves to the outside of the shell and is opposite to the outer peripheral surface of the shell, so that the inner detection rod 31 and the outer detection rod 34 can simultaneously detect the inner cavity size and the outer size of the shell, which can greatly improve the detection efficiency.

[0067] After the shell detection is completed, the motor shaft 511 of the driving motor 51 rotates, driving the transmission gear 52 connected to the motor shaft 511 to move, and the transmission gear 52 drives the inner detection rod 31 to move upward, so that the first rangefinder 33 of the inner detection rod 31 moves to the outside of the shell. At the same time, the inner detection rod 31 drives the outer detection rod 34 connected to the connecting plate 14 to move synchronously through the connecting plate 14, so that the outer detection side rod is staggered from the outer peripheral surface of the shell, so that the inner detection rod 31 and the outer detection rod 34 can be disengaged from the shell at the same time, which can simplify the operation process and facilitate operation. At this time, the shell can be disassembled from the mounting seat.

[0068] In addition, by arranging the transmission rack 53 on the inner detection rod body 32, after the motor shaft 511 of the driving motor 51 stops rotating, the transmission gear 52 stops rotating, and the transmission rack 53 meshing with the transmission gear 52 also stops moving, thereby being able to position the inner detection rod 31 and avoiding the inner detection rod 31 and the outer detection rod 34 from moving downward under the action of their own gravity.
