It aims to provide at least one beneficial option or create conditions to solve one or more technical problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A battery pack flipping mechanism includes a flipping power mechanism, a flipping component, and a support roller. The flipping component is supported by the support roller and is mounted in a support-type rotational configuration. The flipping power mechanism provides power to the flipping component and enables the flipping component to rotate on the support roller.

[0007] The flipping assembly consists of two flipping wheels mounted on the supporting rollers and an inlet / outlet channel connected between the two flipping wheels. The inlet / outlet channel consists of a lower conveying roller and an upper conveying roller spaced apart vertically.

The material-shifting plate passes through the roller gap to move the battery pack to achieve centering. The centering power mechanism drives the two connecting plates to move towards and away from each other through the bidirectional lead screw connected to the lead screw nut.

[0011] More preferably, there are at least two material feeding plates, which are evenly installed on the connecting plate.

[0012] More preferably, the power mechanism for centering is an electric motor.

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings, making the technical solution and beneficial effects of this utility model clearer and more explicit. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] Additional aspects and advantages of this invention will become apparent in the description that follows, or may be learned by practice of this invention.

[0028] Reference Figure 1 As shown, a battery pack flipping mechanism includes a flipping power mechanism 1, a flipping component 3, and a support roller 4. The flipping component 3 is supported by the support roller 4, thus forming a support-type rotatable mounting. The flipping power mechanism 1 provides flipping power to the flipping component 3, enabling the flipping component 3 to rotate on the support roller 4. In this embodiment, the flipping power mechanism 1 is preferably a drive motor, which is connected to the flipping component 3 via a chain 2. Obviously, those skilled in the art can use other known or future-featured power mechanisms to replace the motor, as long as they can drive the flipping component 3 to flip.

[0029] Combination Figure 4 , Figure 5As shown, the flipping assembly 3 consists of two flipping wheels 301 mounted on the bearing roller 4 and an inlet / outlet channel connected between the two flipping wheels 301. The inlet / outlet channel consists of a lower conveying roller 302 and an upper conveying roller 303 spaced apart vertically. A centering mechanism 304 is provided on the left and / or right side of the inlet / outlet channel, and a pressing mechanism 305 is provided on the upper and / or lower side of the inlet / outlet channel.

[0030] It should be noted that the lower conveying roller 302 and the upper conveying roller 303 have the same structure. Correspondingly, a roller drive power mechanism can be provided for the lower conveying roller 302 and the upper conveying roller 303 to drive them to rotate. In some embodiments, the roller drive power mechanism can be omitted, and the battery pack 5 can enter and exit the feed channel by pushing the upper battery pack with the lower battery pack. In some embodiments, the structures of the lower conveying roller 302 and the upper conveying roller 303 are different; this is not limited to this embodiment.

[0031] During operation, the drive motor drives the flipping assembly 3 to flip via the chain 2. Both the lower conveying roller 302 and the upper conveying roller 303 are powered and can deliver the battery pack 5 to the lower work station.

[0032] Combination Figure 2 As shown, the centering mechanism 304 includes a lead screw nut 3041, a material-shifting plate 3042, a connecting plate 3043, a bidirectional lead screw 3044, a linear slide rail 3045, and a centering power mechanism 3046. The connecting plate 3043 is connected to the linear slide rail 3045 to form a sliding connection that allows it to move back and forth. The lead screw nut 3041 and the material-shifting plate 3042 are mounted on the connecting plate 3043. The lead screw nut 3041 is used to connect the bidirectional lead screw 3044. The material-shifting plate 3042 passes through the roller gap to move the battery pack 5 to achieve centering. The centering power mechanism 3046 drives the connecting plate 3043 to move back and forth through the bidirectional lead screw 3044 connected to the lead screw nut 3041.

[0033] In this embodiment, there are three material guide plates 3042, evenly installed on the connecting plate 3043, which achieves optimal centering effect. In some embodiments, there are at least two material guide plates 3042 or one material guide plate, not limited to this embodiment. In this embodiment, the centering power mechanism 3046 is preferably a servo motor.

[0034] During operation, the servo motor drives the bidirectional lead screw 3044 to rotate, thereby causing the two side material guide blocks 3042 to center and clamp the battery pack, achieving centering of the battery pack. The linear slide rail 3045 serves as a guide. In some embodiments, the linear slide rail 3045 can be replaced by other existing known or future achievable guiding mechanisms.

[0035] Combination Figure 3 As shown, the pressing mechanism 305 includes a pressing frame 3051, a linear bearing 3052, a guide rod 3053, and a pressing power mechanism 3054. The pressing frame 3051 has several pressing plates that pass through the roller gap and press against the battery pack 5. The linear bearing 3052 is mounted on the pressing frame 3051, and the guide rod 3053 passes through the linear bearing 3052. The pressing power mechanism 3054 drives the pressing frame 3051 to move back and forth along the guide rod 3053. In this embodiment, the pressing mechanism 305 is located below the lower conveying roller 302, and preferably, the pressing power mechanism 3054 is a cylinder. In some embodiments, the pressing power mechanism 3054 is a hydraulic cylinder or a linear motor, etc. In some embodiments, the linear bearing 3052 and the guide rod 3053 can be replaced by other known or future-featured slide rail structures; this is not limited to this embodiment.

[0036] During operation, the cylinder pushes the top pressure frame 3051 upward, which interacts with the upper conveying roller 303 to clamp the battery pack 5, and then the flipping mechanism flips it. The linear bearing 3052 and the guide rod 3053 provide guidance.

[0037] Combined Figure 1 , Figure 4 As shown, there are four supporting rollers 4, arranged symmetrically in pairs to support one of the flipping rollers 301. The supporting rollers 4 are mounted on a base frame 6, which is a square frame with intersecting reinforcing ribs inside. The base frame 6 facilitates the movement or transport of the entire battery pack flipping mechanism.

[0038] The battery pack flipping mechanism provided in this embodiment works as follows: 1) This flipping mechanism is used in conjunction with a conveyor line; the conveyor line feeds the battery pack 5 into the flipping mechanism, and the battery pack 5 stops moving forward after reaching its destination; 2) The centering mechanism 304 clamps the battery pack 5, positioning it in the middle of the conveyor line, while also preventing the battery pack 5 from slipping during flipping; 3) The pressing mechanism 305 presses down on the battery pack 5, clamping it tightly to ensure its stability during flipping; 4) The flipping mechanism drives the battery pack 5 to flip together, stopping after flipping 180 degrees; 5) The pressing mechanism 305 retracts, and the centering mechanism 304 releases; 6) The battery pack 5 flows out of the flipping mechanism.

[0039] Compared with the prior art, the battery pack flipping mechanism provided in this embodiment has the following advantages: 1) Since the battery pack inlet and outlet channels are located between the two flipping wheels 301, when the battery pack 5 enters the inlet and outlet channels, the centering mechanism 304 and the top pressing mechanism 305 can better fix the battery pack 5 during flipping, making it less likely to fall off and the flipping process more stable. 2) Since this utility model uses four heavy-duty support rollers at the bottom as support, and the flipping wheels are flipped by belt and motor transmission, the flipping structure is simpler and installation and flipping are more convenient.
