Description

Technical Field

[0002] In the battery manufacturing process, the battery casing, equipped with grids, needs to be rotated 180° and fastened onto a cover with sealant applied to its edges to assemble the battery. Chinese Patent CN210074052U discloses a battery flipping and cover-fastening device. This device uses a lifting mechanism to transport the battery box into a rectangular frame, and a clamping cylinder to push clamping blocks to clamp the battery box. After the lifting mechanism resets, a flipping motor rotates the entire rectangular frame one full turn, causing the battery box opening to face downwards, thus achieving the flipping of the battery box. However, this device has the following drawbacks: the suspended structure used for flipping the battery box may cause displacement within the rectangular frame during rotation, resulting in a misalignment between the flipped battery box and the cover below, affecting the closing effect.

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Specific Implementation Example 1:

In use, multiple battery boxes are transported to positions corresponding to the clamping assembly 6 via the power conveyor belt 2. The lifting drive assembly 4, through the rotation drive assembly 5, drives the clamping assembly 6 downward, clamping the battery boxes. The lifting drive assembly 4 then moves the clamped battery boxes upward a certain distance, while the limiting assembly 7 provides omnidirectional limiting for the battery boxes. The rotation drive assembly 5, through the clamping assembly 6, rotates the battery boxes 180°, and the cover conveyor 3 transports the cover directly below the clamped battery boxes. After the battery boxes have finished flipping, the lifting drive assembly 4 moves the battery boxes downward, causing the cover to be placed on the cover. Finally, the clamping assembly 6 releases its grip on the battery boxes and moves upward to the reset state, thus realizing the battery flipping and cover closing operation. This not only effectively improves the efficiency and effect of battery flipping and cover closing but also avoids problems such as battery displacement during the flipping process, ensuring the production quality of the batteries.

The opposite sides of the clamped batteries are respectively in contact with the opposite inner sides of the two adjacent positioning strips 603, thus ensuring the clamping effect of the batteries. Specific Implementation Example 3:

[0040] Based on specific embodiment one, as follows Figure 6 , Figure 8-10 and Figure 12 As shown, the limiting component 7 includes a pair of limiting strips 701 respectively disposed on opposite sides of the positioning clamp 601; the two limiting strips 701 are disposed on opposite sides of the movable frame 501, and the limiting strips 701 are parallel to the drive shaft 502; each of the opposite inner surfaces of the two limiting strips 701 is provided with a guide slope 7011; the guide slope 7011 is disposed at an edge of the limiting strip 701 near the drive shaft 502; each of the opposite inner surfaces of the two limiting strips 701 is provided with a pair of sliding grooves 7012 arranged side by side; the length direction of the sliding grooves 7012 is perpendicular to the length direction of the limiting strips 701; a driven block 7013 is slidably connected in the sliding grooves 7012; a directional post 702 parallel to the positioning strip 603 is vertically fixed on one surface of the driven block 7013; a first mounting block 703 is slidably sleeved on the directional post 702; the first mounting block 703 is fixed on the positioning clamp 601; the first mounting block 703...

When the battery box is clamped and driven to a suspended state, the transmission screw 707 is driven to move closer to the positioning clamp 601 by rotating the spiral sleeve 706, causing the guide inclined surface 7011 to abut against the edge of the battery box. As the limiting plate 701 continues to move closer to the battery box, the limiting plate 701 moves away from the positioning clamp 601, thereby limiting the battery box. Specific Implementation Example 4:

[0042] Based on the third specific embodiment, as follows Figure 4-5As shown, a pair of stop rods 8 parallel to the side support beam 1 are horizontally arranged on both sides of the rotary drive assembly 5. The two pairs of stop rods 8 are respectively arranged between the two support frames 401, and the two stop rods 8 on the same straight line are respectively fixed to the side arms of the two support frames 401 at opposite ends. A first clearance gap is formed between the two stop rods 8 on the same straight line for the transmission screw 707 to pass through. A second clearance gap is formed between the stop rods 8 and the power conveyor belt 2 for the bearing plate 302 to pass through. After the cover closing operation is completed, the battery is on the bearing plate 302. As the bearing plate 302 is reset, the battery moves closer to the stop rods 8, and under the blocking action of the stop rods 8, the battery moves from the bearing plate 302 to the power conveyor belt 2, thereby realizing the battery repositioning.

[0043] Among them, such as Figure 4-6 , Figure 8-9 and Figure 11-12As shown, a drive assembly 9 is connected to the limiting assembly 7; the drive assembly 9 includes a transmission rack 901 vertically fixed on any stop rod 8 between the two support frames 401 and a drive sleeve 902 rotatably inserted into the edge of the movable frame 501; the drive sleeve 902 is arranged parallel between the two transmission screws 707; a transmission gear 903 that can mesh with the transmission rack 901 is fixedly sleeved on the outer periphery of one end of the drive sleeve 902; the inner cross-section of the drive sleeve 902 is a regular polygonal structure; a matching movable column 904 is slidably inserted into one end of the drive sleeve 902; a first transmission shaft 9041 is coaxially fixed to one end of the movable column 904; one end of the first transmission shaft 9041 is rotatably connected to the positioning clamp 601 away from the drive.

At this time, the limiting plate 701 does not limit the battery box, and the position of the limiting plate 701 does not affect the battery entering between the two positioning clamps 601. When the battery is clamped and moves upward, the transmission gear 903 rolls on the transmission rack 901, causing the spiral sleeve 706 to rotate, thereby limiting the battery box with the limiting plate 701. When the battery moves upward to the flip position, the transmission rack 901 and the transmission gear 903 are in a disengaged state, and the position of the transmission gear 903 does not affect the flipping of the battery box.
