DETAILED DESCRIPTION

[0019] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Lithium battery testing device, such as Figure 1 As shown, a support plate 2 is vertically provided at the rear end portion of the upper end surface of the base 1, a horizontally arranged battery conveying device 3 is fixedly provided at the front end portion of the upper end surface of the base 1, a cylindrical battery turning device 4 is provided on the support plate 2, a battery detection device 5 is fixedly provided on the upper end surface of the support plate 2, a control device 10 is fixedly provided on the rear end surface of the support plate 2, an alarm device 7 is provided at the corner of the upper end portion of the front end surface of the support plate 2, and an arc-shaped battery support plate 9 for battery support is provided in the middle portion of the support plate 2;

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, the battery pushing device 6 is located behind the support plate 2, and the push plate on the battery pushing device 6 can pass through the through hole on the support plate 2 through the linear drive motor to push the battery;

[0023] like Figure 2 and Figure 3As shown, the left flip plate 41 for the battery and the right flip plate 42 for the battery on the cylindrical battery flip device 4 are placed vertically and parallel, the lower end surfaces of the left flip plate 41 for the battery and the right flip plate 42 for the battery are connected to the flip plate transmission device 43 through a hinge device, and the motor shaft of the rotating motor 44 for the transmission device fixed on the support plate 2 is fixedly connected to the middle part of the connecting rod 431, so that the flip plate transmission device 43 can make an arc motion on the support plate 2. Since the left flip plate 41 for the battery and the right flip plate 42 for the battery are respectively raised and lowered on the vertical column 8 through the slider, the two vertical columns 8 can move horizontally on the support plate 2, so When the transmission device 43 for the rotating plate makes an arc motion on the support plate 2, the left flip plate 41 for the battery and the right flip plate 42 for the battery move in opposite directions in the vertical direction; the transmission device 43 for the flip plate includes a connecting rod 431, and the two ends of the connecting rod 431 are respectively connected with a connecting ring 432 by a left thread and a right thread. The connecting ring 432 connects the left flip plate 41 for the battery and the right flip plate 42 for the battery through a hinge device. The two end surfaces of the connecting rod 431 are respectively fixedly connected to the rotating motor A433 and the counterweight block 434, and the rotating motor A433 and the counterweight block 434 are respectively slidably connected to the support plate 2 through sliders.

[0024] When in use, the battery to be tested is first manually placed on the battery support plate 9, and then the transmission device 43 for the flip plate is started through the control device 10 to rotate the connecting rod 431. Since the two connecting rings 432 are respectively connected to the connecting rod 431 through the left thread and the right thread, when the connecting rod 431 rotates in one direction, the two connecting rings 432 move in different directions on the connecting rod 431. When the distance between the two connecting rings 432 is shortened, the left flip plate 41 and the right flip plate 42 for the battery connected to the two connecting rings 432 through the hinge device will gather together with the vertical column 8 toward the middle of the connecting rod 431, and then clamp the battery placed on the battery support plate 9;

[0025] After clamping the battery, start the rotating motor 44 for the transmission device to rotate the connecting rod 431. Since the two ends of the connecting rod 431 are slidably connected to the support plate 2 through the rotating motor A433 and the counterweight 434, when the connecting rod 431 rotates, the rotating motor A433 and the counterweight 434 also rotate together with the connecting rod 431.

[0026] At this time, since the connecting ring 432 is connected to the left flip plate 41 for the battery and the right flip plate 42 for the battery through a hinge device, the angle between the connecting ring 432 and the left flip plate 41 for the battery and the right flip plate 42 for the battery can be changed, which will not affect the rotation of the connecting rod 431. During the rotation process, the connecting rod 431 will take the two connecting rings 432 to rise and fall respectively, and will take the left flip plate 41 for the battery and the right flip plate 42 for the battery to rise and fall respectively. Then, the battery clamped by the left flip plate 41 for the battery and the right flip plate 42 for the battery will be flipped due to the friction between the rising (or falling) of the left flip plate 41 for the battery and the falling (or rising) of the right flip plate 42 for the battery. During the battery flipping process, the battery detection device 5 located above the support plate 2 can detect the battery in the flipping process. If the battery detected by the battery detection device 5 is qualified, the control device 10 will start the battery pushing device 6 to push the qualified battery to the battery conveying device 3 for conveying to the next step;

[0027] If the battery detected by the battery detection device 5 is unqualified, the control device 10 will alarm through the alarm device 7, and the unqualified device can be taken out manually.

[0028] The above description is only an explanation of the preferred embodiments of the present application and the technical principles and other schemes used. At the same time, the scope of the invention involved in the present application is not limited to the technical scheme formed by a specific combination of the above technical features, but also should cover other technical schemes formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical scheme.
