Description

Technical Field

[0001] The invention relates to the field of battery manufacturing equipment, and in particular to high-precision molding equipment for ultra-thin batteries. Background Art

[0002] After the soft-pack battery is filled with liquid and packaged, a skirt will be formed on the side of the soft-pack battery. The skirt needs to be flattened, cut, folded, and other processes. Therefore, before each process, the battery placed on the conveying mechanism needs to be positioned to determine the location of its skirt so that the subsequent processing steps can be accurately performed. For general soft-pack batteries, the position of their skirts can be detected by CCD cameras. However, with the continuous improvement of manufacturing technology, the thickness of soft-pack batteries is getting thinner and thinner. For some ultra-thin soft-pack batteries, the thickness of the battery body is slightly larger than the thickness of the skirt, resulting in an unclear dividing line between the two. It is difficult for CCD cameras to accurately position the skirt. Therefore, it is necessary to produce an ultra-thin battery high-precision molding device to solve the above-mentioned problems.

[0043] The skirt clamping assembly 29 includes a connecting base plate 291, a connecting vertical plate 292, a first Y-axis slide 293, an elastic connecting member 294, a mounting bracket 295, a clamping cylinder 296, an upper clamping jaw 297 and a lower clamping jaw 298. The connecting vertical plate 292 is fixed to the front side of the connecting base plate 291, the first Y-axis slide 293 is fixed above the connecting base plate 291, the bottom of the elastic connecting member 294 is slidably connected to the first Y-axis slide 293, the front end of the elastic connecting member 294 is an elastic telescopic end and is elastically connected to the connecting vertical plate 292, and the mounting bracket 295 is fixed to the upper side of the elastic connecting member 294. The clamping cylinder 296 is fixed above the mounting bracket 295, and power output ends are provided on the upper and lower sides of the front end of the clamping cylinder 296.

[0050] In the previous process, the vertical pull rod 139 is lifted upward, and the carrier top plate 134 and the upper clamping plate 133 also rise accordingly. At this time, the reset spring 138 is compressed, the workpiece is placed on the lower clamping plate 132, and the vertical pull rod 139 is released. Under the action of the reset spring 138, the carrier top plate 134 moves downward on the guide rod through the guide sleeve 136, thereby driving the upper clamping plate 133 to press the workpiece downward, and the annular magnetic drive track 11 drives the track mover 12 to run around the annular magnetic drive track 11 through the magnetic force, thereby moving the clamping carrier 13 to each processing station. The advantage of this design is that it drives the track power through magnetic force to achieve high-speed and stable transportation of the workpiece, and the transportation position is highly accurate, which can improve production efficiency, improve processing accuracy, improve yield rate and reduce production costs.

[0051] The two ends of the lower clamping plate 132 protrude from the inner side and the outer side of the carrier bottom plate 131 respectively, the cross-section of the lower clamping plate 132 is an inverted trapezoid, and the inner end lower side and the outer end lower side of the lower clamping plate 132 are both provided with a first inclined surface 1321, and the two ends of the upper clamping plate 133 protrude from the inner side and the outer side of the carrier top plate 134 respectively, the cross-section of the upper clamping plate 133 is a trapezoid, and the inner end upper side and the outer end upper side of the upper clamping plate 133 are both provided with a second inclined surface 1331.

[0052] The parts of the upper clamping plate 133 and the lower clamping plate 132 protruding from the carrier top plate 134 and the carrier bottom plate 131 form a wedge shape, so that the thickness of the upper clamping plate 133 and the lower clamping plate 132 at the outermost edges is reduced to provide space for processing operations, such as positioning, folding, cutting and other processes of the battery skirt.

[0055] In some processing stations, the clamping carrier 13 needs to be opened. When the clamping carrier 13 runs to the station that needs to be opened, the lifting head 1393 corresponds to the T-slot 1431. At this time, the lifting drive assembly 142 drives the lifting claw 143 to rise, and the lifting claw 143 lifts the lifting head 1393 upward through the T-slot 1431, thereby driving the upper clamping plate 133 to rise, completing the opening of the clamping carrier 13.

[0056] The folding mechanism 5 includes a Y-axis driving device 51, a connecting bracket 52, a Z-axis driving device 53, an installation box 54 and a folding device 55.

[0057] The battery in the previous process is transported to the front side of the folding device 55. The skirt droops slightly under the action of weight. The Y-axis drive device 51 first drives the installation box 54 to move forward so that the skirt corresponds to the upper folding knife 552 and the lower folding knife 553. Then, the Z-axis drive device 53 drives the installation box 54 to rise, so that the lower folding knife 553 and the folding knife 559 lift the skirt upward to a horizontal state. Then, the first lifting drive device 551 drives the upper folding knife 552 to descend. The upper folding knife 552 corresponds to the battery itself. The side of the battery body, then, the second lifting drive device 554 makes the driving arm 556 rise, and drives the folding knife 559 to swing around the center of the arc hole 541 through the arc track 557 and the folding plate 558, so that the skirt is folded upward by the front end of the folding knife 559. When it is folded to nearly vertical, the upper cutting knife retreats upward. Under the joint driving action of the Y-axis drive device 51 and the second lifting drive device 554, the folding knife 559 folds the skirt to the upper surface of the battery body, thereby completing the two folding processes of the skirt. The advantage of this design is that it can complete the two folding of the skirt at the same time, and fold the skirt to the side and top surface of the battery body in turn, making the folding efficiency higher, and also reducing the manufacturing cost of the equipment.
