[0033] The utility model is further described in detail below in conjunction with specific embodiments.

[0034] Example:

[0035] like Figures 1 to 3 As shown, a fast-paced half-cell battery sorting machine 1 includes a sorting and conveying unit 11 for conveying battery cells 2 along the X direction, a material box positioning bracket 12 arranged on the Y side of the sorting and conveying unit 11, a plurality of sorting suction and placement units 13a straddling the sorting and conveying unit 11 and the material box positioning bracket 12, and a material box replacement unit 14 located below the material box positioning bracket 12.

[0036] The sorting and conveying unit 11 is used to send the battery cells 2 that have completed the performance test along the X direction to the bottom of the sorting suction and release unit 13a. The material box positioning bracket 12 of this embodiment is provided with 18×7 positions 121, and each position 121 positions a material box 3, so the device divides the performance range of the battery cell 2 into 18 large sections and 126 small sections, and different material boxes 3 are used to place battery cells 2 in different performance ranges. The number of positions 121 here is determined according to the number of segments of the performance range and is not a limitation of this patent. The sorting suction and release unit 13a is used to transport the performance test results to the corresponding material box 3. Because the rhythm of the battery cell 2 passing through the sorting and conveying unit 11 is relatively fast, and the rhythm of the sorting suction and release unit 13a going back and forth between the material box 3 and the sorting and conveying unit 11 is relatively slow, in this embodiment, multiple sorting suction and release units 13a are required to synchronously complete the sorting operation. As the work continues, each material box 3 is likely to be filled. When the material box 3 is fully loaded, the material box replacement unit 14 will replace the full material box with an empty material box from below, so that the sorting work can continue without the participation of personnel.

[0037] like Figure 3 and Figure 4As shown, each sorting suction and placement unit 13a includes a first Y-direction translation module 131a, a second Y-direction translation module 131b, a first suction and placement mechanism 132a, and a second suction and placement mechanism 132b. The first Y-direction translation module 131a and the second Y-direction translation module 131b are arranged back to back. The first Y-direction translation module 131a drives the first suction and placement mechanism 132a to move along the Y direction, and the second Y-direction translation module 131b drives the second suction and placement mechanism 132b to move along the Y direction. The first suction and placement mechanism 132a includes a first lifting cylinder 1321a, a first L-shaped frame 1322a and a first adsorption head 1323a. The first L-shaped frame 1322a includes a first vertical plate 13221a and a first bottom plate 13222a that are vertically fixed. The first lifting cylinder 1321a drives the first suction and placement mechanism 132a to move along the Y direction. The first vertical plate 13221a is driven to rise and fall, and the two first adsorption heads 1323a are arranged side by side at the lower part of the first bottom plate 13222a; the second suction and release mechanism 132b includes a second lifting cylinder 1321b, a second L-shaped frame 1322b and a second adsorption head 1323b, the second L-shaped frame 1322b includes a vertically fixed second vertical plate 13221b and a second bottom plate 13222b, the second lifting cylinder 1321b drives the second vertical plate 13221b to rise and fall, and the two second adsorption heads 1323b are arranged side by side at the lower part of the second bottom plate 13222b; the first bottom plate 13222a and the second bottom plate 13222b are staggered up and down so that the first adsorption head 1323a and the second adsorption head 1323b move in the same Y-direction strip area without colliding with each other.

[0038] The first suction and release mechanism 132a and the second suction and release mechanism 132b are equivalent components, which are responsible for the discharge work of the same row of bins 121. They both use the Y-direction translation module to complete the Y-direction movement, and use the lifting cylinder to complete the lifting of the adsorption head, and then the adsorption head controls the adsorption and release of the battery cell 2. The material picking position and material discharge position of the first suction and release mechanism 132a and the second suction and release mechanism 132b overlap, but the movement of the two needs to be staggered. In other words, when the first suction and release mechanism 132a goes to the top of the sorting and conveying unit 11 to pick up materials, the second suction and release mechanism 132b puts materials on the material box positioning bracket 12; when the second suction and release mechanism 132b goes to the top of the sorting and conveying unit 11 to pick up materials, the first suction and release mechanism 132a puts materials on the material box positioning bracket 12. When the translation is performed, the heights of the two and the battery cell 2 are staggered, which makes reasonable use of the upper space of the equipment and will not cause collision problems. The first suction and placement mechanism 132a and the second suction and placement mechanism 132b, one takes the sheets from the sorting and conveying unit 11, and the other puts the sheets, and the two actions are performed alternately, doubling the sorting efficiency while keeping the number of sorting suction and placement units 13a unchanged.

[0039] like Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, a plurality of bins 121 for placing the material boxes 3 are arranged in an array on the material box positioning bracket 12, and the material box replacement unit 14 replaces the material box 3 from the bottom of the bin; the material box replacement unit 14 includes a material box conveying line 141, a movable support 142, an XY movable assembly 143 and a lifting mechanism 144, the XY movable assembly 143 drives the movable support 142 to move in the XY plane, the material box conveying line 141 is arranged on the upper part of the movable support 142 and conveys the material box 3 along the X direction, and the lifting mechanism 144 is fixedly arranged on the lower part of the movable support 142 and is located below the middle part of the material box conveying line 141.

[0040] like Figures 1 to 3 As shown, a collecting bin 15 is provided at the outlet end of the sorting and conveying unit 11 .

[0041] If the performance of the delivered battery cell 2 does not meet the sorting interval requirements or due to some unexpected circumstances, all sorting suction and release units 13a will not take away the battery cell 2, then the battery cell 2 will continue to flow along the sorting and conveying unit 11 to the end and fall into the collecting bin 15 for collection, which is convenient for processing.

[0042] like Figure 2 As shown, the sorting and conveying unit 11 includes two conveying lines 111 arranged side by side.

[0043] The sorting and conveying unit 11 is divided into two conveying lines 111 so as to independently control the conveying positions of the two battery cells 2, so that the two battery cells 2 can be adjusted to be aligned before being sucked by the first suction and placement mechanism 132a or the second suction and placement mechanism 132b.

[0044] like Figure 1 and Figure 2 As shown, a feed conveying unit 16 and a feed suction and release unit 13b are provided on the entrance side of the sorting and conveying unit 11. The feed conveying unit 16 conveys along the X direction. The feed suction and release unit 13b has the same structure as the sorting and conveying unit 13a. The feed suction and release unit 13b straddles the discharge section of the feed conveying unit 16 and the feed section of the sorting and conveying unit 11.

[0045] The sorting and conveying unit 11 and the material box positioning bracket 12 are arranged on both sides of the half-cell battery sorting machine 1 in the Y direction, but the battery cell 2 needs to enter from the middle of the wide side of the half-cell battery sorting machine 1. Although the feeding and conveying unit 16 has the same conveying direction as the sorting and conveying unit 11, the position is staggered, and the feeding suction and placement unit 13b is required to perform a transfer. The feeding suction and placement unit 13b also has a very fast transfer speed.

[0046] like Figure 2 As shown, the feed conveying unit 16 includes a pair of feed conveying lines 161 arranged side by side in the Y direction, and a steering unit 17 for horizontally rotating the battery cell 2 by 180° is provided above the middle section of one of the feed conveying lines 161.

[0047] A half-cell battery is obtained by cutting a large cell with rounded corners in half, so when sorting and feeding, the two rounded corners are located on different sides. In order to make the direction of the rounded corners uniform after sorting, after positioning the cell 2, a steering unit 17 is required to specifically rotate a row of cells 2 horizontally by 180°.

[0048] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
