[0052] The clamping component 4 is rotatably installed on the bracket group. The clamping component 4 includes a first clamping member 41 and a second clamping member 42. The first clamping member 41 and the second clamping member 42 are arranged at intervals along the first direction, and the first clamping member 41 and the second clamping member 42 are located between the first bracket 2 and the second bracket 21.

[0053] The adjusting component 5 is installed between the bracket group and the clamping component 4 and is used to adjust the distance between the first clamping member 41 and the second clamping member 42. In this way, through the setting of the adjusting component 5, it is more convenient to adjust the distance between the first clamping member 41 and the second clamping member 42 according to the size of the battery pack to adapt to battery packs of different sizes.

In this way, through the setting of the detection component 6, each surface of the battery pack is detected, thereby reducing the probability of damage to the battery pack during transfer on each line.

[0055] With the above structure, when it is necessary to detect the battery pack, first, the transportation component transports the battery pack to be detected to the detection component 6, then the adjusting component 5 adjusts the distance between the first clamping member 41 and the second clamping member 42 according to the size of the battery pack to be detected to adapt to the size of the battery pack to be detected, and then the clamping component 4 clamps the battery pack to be detected on the transportation component, and then drives the clamping component 4 to rotate, which is convenient for the detection component 6 to detect each surface of the battery pack.

[0056] An optional implementation manner of this embodiment is as follows: The transportation component includes a plurality of conveying rollers 3, all of which are rotatably installed on the base 1.

[0059] The second detection component 6 is installed on the bracket group, and the second detection component 6 is used to detect the circumferential surface of the battery pack. It should be noted that the end surface in contact with the conveying roller 3 is the bottom end of the battery pack, the end surface opposite to the bottom end is the top end, and the circumferential surface of the battery pack is the surface excluding the bottom end and the top end of the battery pack. In this way, through the setting of the first detection component 6 and the second detection component 6, the purpose of detecting all surfaces of the battery pack is achieved.

[0060] An alternative implementation of this embodiment is as follows: The first detection component 6 includes two first X-ray probes 61. The two first X-ray probes 61 are arranged at intervals along the third direction and are respectively located above and below the transportation component. The first direction, the second direction, and the third direction are perpendicular to each other in pairs. In this way, when the transportation component transports the battery pack to be detected to the first detection component 6, the first X-ray probe 61 located above the transportation component detects the upper part of the battery pack, and the first X-ray probe 61 located below the transportation component detects the lower part of the battery pack through the gap between two adjacent conveying rollers 3, so as to achieve the purpose of detecting the top and bottom ends of the battery pack. An alternative implementation of this embodiment is as follows: The second detection component 6 includes two second X-ray probes 62, which are respectively installed on the opposite sides of the first bracket 2 and the second bracket 21. In this way, when the battery pack to be detected is transported to the second detection component 6, it is clamped by the rotationally installed clamping component 4, and then the driving clamping component 4 drives it to rotate, so as to realize the detection of the circumferential surface of the battery pack to be detected. Moreover, the X-ray probe has strong penetration ability and high image resolution, which is more convenient for detecting the battery pack.

[0061] An alternative implementation of this embodiment is as follows: The adjustment component 5 includes a first mounting plate 51, a mounting rod 52, a slider 53, a sliding rod 54, a first cylinder 55, a gear 56, and a rack, where:

The first mounting rod 52 and the second mounting rod 52 are arranged at intervals along the first direction. The first clamping member 41 and the second clamping member 42 are respectively installed on the first mounting rod 52 and the second mounting rod 52. Through the setting of the mounting rod 52, it is convenient to connect the clamping component 4 and the adjustment component 5.

[0063] The number of the sliding blocks 53 is four. Two of the sliding blocks 53 are installed on the first mounting rod 52 and located at both ends of the first mounting rod 52. The remaining two sliding blocks 53 are installed on the second mounting rod 52 and located at both ends of the second mounting rod 52. That is, the four sliding blocks 53 are respectively located at the four vertices of the same rectangle.

[0064] The number of the sliding rods 54 is four, and all are installed at the bottom end of the first mounting plate 51. The four sliding blocks 53 are respectively slidably installed on the four sliding rods 54. The four sliding blocks 53 and the four sliding rods 54 are arranged in one-to-one correspondence. And the axes of the four sliding rods 54 are all arranged along the first direction. Through the arrangement of the sliding rods 54, the sliding blocks 53 can move along the first direction.

The axis of the first air cylinder 55 is arranged along the first direction, and the telescopic end of the first air cylinder 55 is connected to any one of the sliding blocks 53. The structure of the air cylinder is simple and compact, with fast response speed, easy to maintain and convenient to install.

[0066] The gear 56 is rotatably installed at the bottom end of the first mounting plate 51 and located at the center of the first mounting plate 51.

[0067] There are two racks, namely the first rack 57 and the second rack 58. One end of the first rack 57 meshes with the gear 56, and the other end is installed on the first mounting rod 52; one end of the second rack 58 meshes with the gear 56, and the other end is installed on the second mounting rod 52.

And both the first rack 57 and the second rack 58 are arranged along the first direction. Through the transmission of the gear 56 and the rack, the bearing capacity is strong and the operation is stable.

[0068] Through the above structure, when it is necessary to adjust the distance between the first clamping member 41 and the second clamping member 42, first, the first air cylinder 55 drives any one of the sliding blocks 53 to slide on the corresponding sliding rod 54, so that the mounting rod 52 connected to the sliding block 53 moves synchronously along the first direction, and then drives the clamping member connected to the mounting rod 52 to move synchronously in the first direction. At the same time, it drives the rack connected to the mounting rod 52 to move in the first direction. When the rack moves, it drives the gear 56 meshing with it to rotate, so that the other rack meshing with the gear 56 moves in the direction of approaching or separating from each other. When the other rack moves, it drives the mounting rod 52 connected to it to move synchronously, and further drives the two sliding blocks 53 connected to the mounting rod 52 to move on the corresponding sliding rods 54. At the same time, it drives the other clamping member connected to the mounting rod 52 to move synchronously, so as to achieve the purpose of changing the distance between the first clamping member 41 and the second clamping member 42.

[0069] An alternative implementation of this embodiment is as follows: It further includes a rotating component, which is installed between the bracket group and the adjusting component 5.

It should be noted that the servo motor 7 is electrically connected to the power supply through a circuit, and a switch for controlling the on / off of the circuit is provided on this circuit. This switch can be a wired switch or a wireless switch. Using the rotating servo motor 7 as the power source can provide stable rotational power and is convenient for control.

[0071] An alternative implementation of this embodiment is as follows: It further includes a driving component 8, which is installed between the bracket group and the rotating component and is used to drive the servo motor 7 to perform a linear reciprocating motion along the third direction. Through the setting of the driving component 8, the servo motor 7 performs a linear reciprocating motion in the third direction, so that the clamping component 4 indirectly installed with the servo motor 7 synchronously performs a linear reciprocating motion in the third direction, and at the same time, the battery pack clamped on the clamping component 4 synchronously moves up and down between the two second X-ray probes 62, thereby making the battery pack scanned more comprehensively and improving the detection quality.
