Description

Technical Field

[0001] This disclosure relates to the field of battery pack weighing and testing technology, specifically to a battery pack weight and visual inspection device. Background Technology

[0002] After manufacturing, battery packs need to be weighed and visually inspected to promptly detect any abnormalities. In related technologies, an AGV (Automated Guided Vehicle) arrives at the weighing and inspection equipment, and then an operator starts a transfer machine. The transfer machine picks up the battery pack from the vehicle and moves it to the inspection position. After inspection, the battery pack is transported to the next processing equipment. This method places a heavy workload on the transfer machine and requires worker intervention. Summary of the Invention

[0003] To overcome the problems of existing battery pack weighing and visual inspection equipment requiring manual intervention and the heavy workload of transfer machines.

[0004] To achieve the above objectives, this disclosure provides a battery pack weight and visual inspection device, comprising:

[0005] The protective fence has oppositely positioned entrances and exits.

[0006] An AGV positioning mechanism is installed between the entrance and the exit. The AGV positioning mechanism includes two positioning brackets, two photoelectric through-beam sensors and two pin cylinders respectively mounted on the two positioning brackets. The two positioning brackets are arranged opposite to each other, and the area between them is used for the passage of the AGV. The AGV is provided with a limiting hole for plugging into the output end of the pin cylinder. The two through-beam sensors are used to detect whether there is a battery pack on the AGV.

[0007] A top surface inspection mechanism, installed inside the protective fence, is used to inspect the top surface of the battery pack;

[0008] A bottom and side inspection mechanism, installed within the protective fence, is used to inspect the bottom and sides of the battery pack; and

[0009] A gripping and weighing mechanism, installed inside the protective fence, is used to grip and transfer the battery pack.

[0010] Optionally, the top surface detection mechanism includes an X-axis motion component, a Y-axis motion component, a Z-axis motion component, a 2D planar CCD camera, and a 3D camera. The X-axis motion component is mounted on the ground, the Y-axis motion component is connected to the X-axis motion component, the Z-axis motion component is mounted on the Y-axis motion component, and both the 2D planar CCD camera and the 3D camera are mounted on the Z-axis motion component. The X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0011] Optionally, the bottom and side detection mechanism includes a fixed base, a 2D planar CCD camera, an X-axis motion component, and a Y-axis motion component. The fixed base is installed on the ground, the X-axis motion component is installed on the fixed base, the Y-axis motion component is connected to the X-axis motion component, and the 2D planar CCD camera is installed on the Y-axis motion component. The 2D planar CCD camera, the X-axis motion component, and the Y-axis motion component are in five groups. The five fixed bases enclose a detection cavity with a bottom and side surface, and the battery pack extends into the detection cavity.

[0012] Optionally, the gripping and weighing mechanism includes a transfer assembly and a weight detection assembly. The weight detection assembly includes a mounting plate, a weighing sensor, a distance sensor, four gripper cylinders, and four locking cylinders.

[0014] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0015] The frame provides overall structural support and features relatively positioned entrances and exits for easy access for the AGV (Automated Guided Vehicle). The AGV positioning mechanism uses two positioning brackets and photoelectric sensors and pin-type cylinders mounted on them to precisely place and position the AGV, ensuring accurate detection of the battery pack. The top surface detection mechanism detects and analyzes the top surface of the battery pack, while the bottom and side surface detection mechanisms inspect the bottom and sides, ensuring comprehensive, blind-spot-free inspection.

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0025] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "front," "rear," "left," and "right" are used for ease of description based on the drawing orientations of the corresponding figures, while "inner" and "outer" are defined based on the contours of the corresponding components themselves. Terms such as "first" and "second" used in this disclosure are used to distinguish one element from another and do not have sequential or importance implications. Furthermore, when the following description refers to the figures, unless otherwise indicated, the same numbers in different figures represent the same or similar elements.

[0026] Please see Figures 1 to 3 This disclosure provides a battery pack weight and visual inspection device, including a protective fence 1, an AGV (Automated Guided Vehicle) positioning mechanism 300, a top surface inspection mechanism 100, a bottom and side surface inspection mechanism 200, and a gripping and weighing mechanism 400. The protective fence 1 has an exit 12 and an entrance 11 arranged opposite to each other. The AGV positioning mechanism 300 is installed between the entrance 11 and the exit 12. The AGV positioning mechanism 300 includes two positioning brackets 301, two photoelectric through-beam sensors 302 and two pin cylinders 303 respectively mounted on the two positioning brackets 301. The two positioning brackets 301 are arranged opposite to each other, and the area between them is for the passage of the AGV. The AGV has a limiting hole for connecting to the output end of the pin cylinder 303. The two through-beam sensors are used to detect whether there is a battery pack (not shown in the figure) on the AGV. The top surface inspection mechanism 100 is installed inside the protective fence 1 and is used to detect the top surface of the battery pack. A bottom and side inspection mechanism 200 is installed inside the protective fence 1 to inspect the bottom and sides of the battery pack. A gripping and weighing mechanism 400 is installed inside the protective fence 1 to grip and transfer the battery pack.

[0027] Understandably, the frame provides support for the overall structure and features a relatively positioned entrance 11 and exit 12 for easy access for the AGV cart. The AGV cart positioning mechanism 300 precisely positions and positions the AGV cart using two positioning brackets 301, photoelectric through-beam sensors 302 mounted on them, and a pin-type cylinder 303, ensuring accurate detection of the battery pack. The top surface detection mechanism 100 detects and analyzes the top surface of the battery pack, while the bottom and side surface detection mechanism 200 detects the bottom and sides of the battery pack, ensuring comprehensive, blind-spot-free detection. The gripping mechanism mechanically captures and transfers the battery pack, facilitating its transfer between different detection stations. After detection, the gripping mechanism places the battery pack onto the AGV cart, eliminating the need for a transfer machine to move the battery pack to the next process. These devices work together to automate the entire process of battery pack processing from feeding, positioning, detection, and transfer, significantly improving detection efficiency and accuracy, reducing errors caused by manual operation, and enhancing the safety and reliability of the production process.

[0028] In one implementation, please refer toFigure 1 and Figure 4 The top surface inspection mechanism 100 includes an X-axis motion component 103, a Y-axis motion component 104, a Z-axis motion component 105, a 2D planar CCD camera 101, and a 3D camera 102. The X-axis motion component 103 is mounted on the ground, the Y-axis motion component 104 is connected to the X-axis motion component 103, and the Z-axis motion component 105 is mounted on the Y-axis motion component 104. The 2D planar CCD camera 101 and the 3D camera 102 are both mounted on the Z-axis motion component 105, with the X, Y, and Z axes perpendicular to each other. The 2D planar CCD camera 101 and the 3D camera 102 can move in the X, Y, and Z axes to ensure accurate inspection of the top surface of the battery pack. The X-axis motion component 103, the Y-axis motion component 104, and the Z-axis motion component 105 can be a combined robotic arm or a linear module, etc., without specific limitations. The 2D planar CCD camera 101 and the 3D camera 102 are existing technologies and will not be described in detail here.

[0029] In one implementation, please refer to Figure 2 and Figure 4 The bottom and side surface detection mechanism 200 includes a fixed base 201, a 2D planar CCD camera 101, an X-axis motion component 103, and a Y-axis motion component 104. The fixed base 201 is mounted on the ground, the X-axis motion component 103 is mounted on the fixed base 201, the Y-axis motion component 104 is connected to the X-axis motion component 103, and the 2D planar CCD camera 101 is mounted on the Y-axis motion component 104. There are five sets of 2D planar CCD cameras 101, X-axis motion components 103, and Y-axis motion components 104. The five fixed bases 201 enclose a detection cavity with a bottom and side surface, into which the battery pack extends. By setting the 2D planar CCD camera 101 in five directions, good visual detection of the side and bottom surfaces of the battery pack can be ensured simultaneously. By setting the X-axis motion component 103 and the Y-axis motion component 104, the 2D planar CCD camera 101 can move in multiple directions, improving the detection effect.

[0030] In one implementation, please refer to Figures 4 to 7The gripping and weighing mechanism 400 includes a transfer assembly 410 and a weight detection assembly 420. The weight detection assembly 420 includes a mounting plate 421, a weighing sensor 422, a distance sensor 423, four gripper cylinders 424, and four locking cylinders 425. The weighing sensor 422 is mounted on the top surface of the mounting plate 421, which is connected to the transfer assembly 410 via the weighing sensor 422. The distance sensor 423 is mounted on the bottom surface of the mounting plate 421 and is used to sense the distance between the gripper cylinders 424 and the battery pack, facilitating the control of the movement of the transfer assembly 410 so that it can move the gripper cylinders 424 to the battery pack. The four gripper cylinders 424 are respectively mounted at the four corners of the mounting plate 421. The locking cylinders 425 are used to lock the gripper cylinders 424 to prevent the battery pack from falling due to the failure of the gripper cylinders 424. The grabbing and weighing mechanism 400 grabs the battery pack on the AGV trolley at the AGV trolley positioning mechanism 300. Then, it can drive the battery pack to the top surface inspection mechanism 100 and the bottom and side surface inspection mechanism 200 to perform all-round inspection of the battery pack on six sides, checking for scratches, bolts, labels, water and electricity ports, etc.

[0031] In one implementation, please refer to Figure 6 and Figure 7 The mounting plate 421 is equipped with four slide rails 426, each corresponding to one of the four gripper cylinders 424. Each gripper cylinder 424 includes a cylinder body 4241 and a gripper 4242, which is slidably connected to the slide rails 426. Both the slide rails 426 and the grippers 4242 have locking holes. The output end of the gripper cylinder 424 is used to extend into the locking holes of the slide rails 426 and the grippers 4242 to restrict the grippers 4242 from sliding relative to the slide rails 426. When all four gripper cylinders 424 simultaneously clamp the battery pack, the output end of the locking cylinder 425 sequentially extends into the locking holes of the slide rails 426 and the grippers 4242, preventing the grippers 4242 from sliding relative to the slide rails 426.

[0032] In one embodiment, the protective fence 1 is also equipped with a control cabinet, an entrance roller shutter door, an exit roller shutter door, etc.
