Description

Technical Field

[0001] The invention relates to an electric cell transfer mechanism, in particular to a power electric cell return support transfer mechanism. Background Art

[0002] Double-sided hot pressing of the battery cell can further shape the battery cell and reduce the risk of deformation of the battery cell during the subsequent transfer process. Usually the power winding machine is a cold pressing structure, and the battery cell is directly transferred to the flattening bottom on the belt line for flattening, but this type of structure cannot meet the requirements of double-sided hot pressing of the battery cell. Since the structure of the battery cell is relatively loose before flattening and shaping, the direct use of traditional plywood to scrape the material can easily cause the battery cell to deform, affect the spacing between the tabs or fold the diaphragm, and increase the defective rate of the battery cell. If the claw transfer is directly used, the battery cell is likely to be displaced when the discharge cell is removed, resulting in the battery cell failing to contact the tab well during the short-circuit test, affecting the accuracy of the short-circuit test.

[0026] Working principle: Wait for the working status to be Figure 2As shown; when the battery cell to be corrected is transferred to a suitable position, the battery cell correcting support mechanism 2 moves horizontally from the initial position to the grasping position under the action of the ball screw mechanism 12, and under the action of the clamping claw lifting mechanism 25, the left correcting support mechanism and the right correcting support mechanism slowly descend to the belt line plane. At this time, the first movable block 225 and the second movable block 235 are turned from the open state to the closed state, and the first correcting plate 222 and the second correcting plate 232 move inward, so as to correct the battery cell to be corrected, as shown in FIG. Figure 3 As shown; then the first jaw support plate 221 and the second jaw support plate 231 move inwards under the action of the first jaw support plate driving mechanism 223 and the second jaw support plate driving mechanism 233 respectively, and the jaws of the first jaw support plate 221 and the second jaw support plate 231 extend from the jaw extension openings at the bottom of the first return plate 222 and the second return plate 232 respectively, and extend into the bottom of the battery cell, thereby lifting the battery cell, as shown in FIG. Figure 4 As shown; after the battery cell is lifted up, the first clamping claw support plate 221 and the second clamping claw support plate 231 hold the battery cell and slowly rise up, and the battery cell return support mechanism 2 is driven by the ball screw mechanism 12 and moves horizontally to the flattening structure; the pick plate 26 first reaches the flattening structure, and continues to pick up the original battery cell at the flattening structure onto the flat belt, until the first clamping claw support plate 221, the second clamping claw support plate 231 and the battery cell thereon are in the middle of the flattening structure, at this time, the left return support mechanism and the right return support mechanism slowly descend to the plane where the hot pressing plate is located, and then The first clamping jaw support plate 221 and the second clamping jaw support plate 231 withdraw from the bottom of the battery cell, and after releasing the battery cell, the first movable block 225 and the second movable block 235 are turned from the closed state to the open state, and the left return support mechanism and the right return support mechanism move outward; the left return support mechanism, the right return support mechanism and the pick plate 26 rise upward, and the battery cell return support mechanism 2 returns to its original position under the action of the ball screw mechanism 12; finally, the pick plate 26 slowly descends under the action of the pick plate lifting mechanism 28, enters the waiting state, and waits for the next cycle. Among them, the first return width adjustment structure 224, the second return width adjustment structure 234, and the pick plate driving mechanism 27 can adjust the initial position according to the size of the battery cell to meet the needs of various models.

[0027] Among them, the material removal drive component 1 is not limited to the structural design of the linear guide mechanism 11 and the ball screw mechanism 12, but can also be replaced by other structures, such as: cylinder and linear bearing, cylinder and linear guide, stepper motor driven synchronous belt and linear guide and other linear motion actuators, other rotating mechanisms, etc.
