DETAILED DESCRIPTION

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] Please refer to Figures 1 to 4 This embodiment provides a new energy vehicle battery rapid detection device, including: a base 1, a conveyor belt 2, a battery orientation adjustment mechanism, a battery detection mechanism and a controller, the conveyor belt 2 is arranged on the top of the base 1 along the extension direction of the base 1, and the battery orientation adjustment mechanism and the battery detection mechanism are sequentially arranged on the base 1 along the conveying direction of the conveyor belt 2. The battery orientation adjustment mechanism is used to adjust the orientation of the battery, which is convenient for the connection between the battery detection mechanism and the battery. The battery detection mechanism is used to automatically connect with the battery, thereby realizing automatic and rapid detection of the battery, reducing the labor intensity of the staff, and effectively improving the efficiency of new energy vehicle battery detection.

[0032] The battery orientation adjustment mechanism includes a second bracket 25, a third camera 26, two sets of second electric telescopic rods 8, a fixed plate 12, two sets of sixth electric telescopic rods 27 and a push plate 10. The two ends of the second bracket 25 are respectively arranged on the top of the base 1 through a linear moving module 11, and the linear moving module 11 drives the second bracket 25 to move in a direction parallel to the conveyor belt 2. The third camera 26 is arranged on the second bracket 25 and faces the conveyor belt 2. The two sets of second electric telescopic rods 8 are arranged in parallel on the second bracket 25 and their output ends face the conveyor belt 2. The fixed plate 12 is installed on the output ends of the two sets of second electric telescopic rods 8. The two sets of second electric telescopic rods 8 are linked to drive the lifting of the fixed plate 12. The two sets of sixth electric telescopic rods 27 are installed at the two ends of the fixed plate 12, and the output end of each set of sixth electric telescopic rods 27 is connected to a push plate 10.

[0033] The third camera 26, the linear motion module 11, the second electric telescopic rod 8 and the sixth electric telescopic rod 27 are respectively connected to the controller for communication. The third camera 26 is used to obtain the position data of the battery, determine whether the battery is placed correctly, and adjust the position of the battery by moving the push plate 10.

[0034] When the battery is placed on the conveyor belt 2 after the previous process (manual placement or automatic placement), the battery orientation may not meet the requirements. At this time, the two groups of sixth electric telescopic rods 27 work independently to realize the independent operation of the two push plates 10, thereby correcting the orientation of the battery, so that the output end of the battery data acquisition controller is easy to connect with the detection connector 4 of the battery detection mechanism.

[0035] In this embodiment, in order to avoid damage to the battery, a buffer pad, such as a rubber buffer pad, is provided on the side of the push plate 10 that contacts the battery.

[0036] The battery detection mechanism includes a visual control component for acquiring battery position data and a detection component arranged on the side wall of the base 1 for connecting to the output end of the battery data acquisition controller.

[0037] The detection assembly includes a fixed frame 15, a moving assembly, a connection block 22, a mounting plate 3 and a detection connector 4. The fixed frame 15 is arranged on one side of the base 1, and the moving assembly is respectively connected to the fixed frame 15 and the connection block 22. The moving assembly is a three-axis moving mechanism, which drives the connection block 22 to move in the three directions of X, Y and Z. The mounting plate 3 is connected to the connection block 22, and the detection connector 4 is installed in the middle of the mounting plate 3. The moving assembly can drive the detection connector 4 to move in the three directions of X, Y and Z to achieve the connection between the detection connector 4 and the output end of the battery data acquisition controller.

[0038] In this embodiment, the mobile assembly includes a third electric telescopic rod 16 vertically arranged on a fixed frame 15, a fourth electric telescopic rod 20 arranged at the output end of the third electric telescopic rod 16, a fifth electric telescopic rod 21 arranged at the output end of the fourth electric telescopic rod 20, and a connecting block 22 arranged at the output end of the fifth electric telescopic rod 21. The telescopic directions of the third electric telescopic rod 16, the fourth electric telescopic rod 20 and the fifth electric telescopic rod 21 are perpendicular to each other, and the telescopic direction of the fourth electric telescopic rod 20 is parallel to the conveying direction of the conveyor belt 2, and the detection joint 4 faces the direction of the conveyor belt 2 and is parallel to the telescopic direction of the fifth electric telescopic rod 21. The third electric telescopic rod 16, the fourth electric telescopic rod 20 and the fifth electric telescopic rod 21 are respectively connected to the controller for communication. By controlling the third electric telescopic rod 16, the fourth electric telescopic rod 20 and the fifth electric telescopic rod 21, the position of the detection joint 4 can be adjusted, so as to facilitate docking with the output end of the battery data acquisition controller.

[0039] The visual control component includes a first bracket 7, a first camera 17, a second camera 19, a plurality of elastic telescopic rods 23, and a distance measuring sensor 24 whose number is the same as the number of the elastic telescopic rods 23. The first bracket 7 is arranged on the top of the base 1 and close to the position of the detection component, the first camera 17 and the second camera 19 are arranged on the first bracket 7 and face the conveyor belt 2, and the plurality of elastic telescopic rods 23 are arranged on the mounting plate 3 and around the detection joint 4. The telescopic direction of the elastic telescopic rod 23 is parallel to the telescopic direction of the fifth electric telescopic rod 21, that is, the telescopic direction of the elastic telescopic rod 23 is consistent with the extension direction of the detection joint 4, and a distance measuring sensor 24 is respectively arranged on each elastic telescopic rod 23, and the distance measuring sensor 24 faces the direction where the detection joint 4 is located. The first camera 17, the second camera 19 and the distance measuring sensor 24 are respectively connected to the controller for communication.

[0040] The first camera 17 is used to obtain the position data between the elastic telescopic rod 23 and the output end of the battery data acquisition controller. If interference may occur, the elastic telescopic rod 23 and the output end of the battery data acquisition controller can be avoided from colliding by extending and retracting the fifth electric telescopic rod 21;

[0041] The second camera 19 is used to obtain the position data between the detection joint 4 and the output end of the battery data acquisition controller, and adjust the position of the detection joint 4 through the third electric telescopic rod 16, the fourth electric telescopic rod 20 and the fifth electric telescopic rod 21, so that the detection joint 4 is initially aligned with the output end of the battery data acquisition controller.

[0042] When the detection connector 4 is docked with the output end of the battery data acquisition controller, the distance measuring sensor 24 is used to obtain the distance between the output end of the battery data acquisition controller. After comparing with the preset comparison value, the position of the detection connector 4 can be fine-tuned through the third electric telescopic rod 16, the fourth electric telescopic rod 20 and the fifth electric telescopic rod 21 to achieve accurate docking between the detection connector 4 and the output end of the battery data acquisition controller.

[0043] In order to mark whether the tested battery is qualified, in this embodiment, the first bracket 7 is provided with two first electric telescopic rods 6 respectively connected to the controller for communication, and a qualified labeling machine 13 and an unqualified labeling machine 14 are respectively installed at the bottom of the two first electric telescopic rods 6.

[0044] In this embodiment, the controller adopts a PLC controller, such as Siemens s7-300.

[0045] This embodiment also provides a detection method based on the above-mentioned new energy vehicle battery rapid detection device, comprising the following steps:

[0046] S1: placing the battery at the input end of the conveyor belt 2, the placement method may be manual placement or automatic placement by a robot;

[0047] S2: The conveyor belt 2 works to move the battery to the setting below the second bracket 25;

[0048] S3: The third camera 26 obtains the position data of the battery and determines whether the placement of the battery is correct. If it is correct, the process directly proceeds to step S5; if it is incorrect, the process proceeds to step S4;

[0049] S4: the linear moving module 11 works to move the push plate 10 to the front of the battery (close to the position of the first bracket 7), the second electric telescopic rod 8 drives the push plate 10 to descend, and the sixth electric telescopic rod 27 drives the corresponding push plate 10 to work to adjust the position of the battery to the preset position, and then the sixth electric telescopic rod 27, the second electric telescopic rod 8 and the linear moving module 11 work in reverse order to reset; obviously, if the position of the battery after adjustment is not adjusted to the preset position, step S4 can be repeated until the position of the battery is adjusted to the preset position;

[0050] S5: The conveyor belt 2 continues to work, driving the battery to move. During the movement, the first camera 17 obtains the position data between the elastic telescopic rod 23 and the output end of the battery data acquisition controller, and determines whether the moving trajectory of the output end of the battery data acquisition controller collides with the elastic telescopic rod 23. If not, proceed directly to the next step. If yes, the fifth electric telescopic rod 21 works to move the elastic telescopic rod 23 away from the conveyor belt 2 until the moving trajectory of the output end of the battery data acquisition controller does not collide with the elastic telescopic rod 23, and then proceed to the next step;

[0051] S6: The conveyor belt 2 moves the battery to a setting below the first bracket 7;

[0052] S7: The second camera 19 obtains the position data between the detection joint 4 and the output end of the battery data acquisition controller, and determines whether the detection joint 4 and the output end of the battery data acquisition controller are preliminarily aligned. If so, proceed to the next step. If not, adjust the position of the detection joint 4 by the third electric telescopic rod 16 and the fourth electric telescopic rod 20, so that the detection joint 4 and the output end of the battery data acquisition controller are preliminarily aligned, and then proceed to the next step;

[0053] S8: The fifth electric telescopic rod 21 drives the detection joint 4 to move, so that the detection joint 4 is docked with the output end of the battery data acquisition controller. During the movement, the elastic telescopic rod 23 is deformed under the extrusion to avoid interference with the docking between the detection joint 4 and the output end of the battery data acquisition controller. At the same time, the distance measuring sensor 24 obtains the distance between the output end of the battery data acquisition controller, and after comparing it with the preset comparison value, fine-tuning is performed through the third electric telescopic rod 16 and the fourth electric telescopic rod 20 to improve the accuracy of docking;

[0054] S9: Detect the battery. After the detection is completed, the detection connector 4 is separated from the output end of the battery data acquisition controller through the fifth electric telescopic rod 21, and the battery is marked as qualified or unqualified through the first electric telescopic rod 6;

[0055] S10: Repeat steps S1 to S9 to implement repeated detection of the battery.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
