Description

Technical Field

[0001] The present invention relates to the technical field of battery production equipment, and particularly relates to an automatic shaping mechanism for assembling battery plates. Background Art

[0002] During the production process of lead-acid batteries, the plates are important components. With the development of battery production technology, in the existing processing, in order to increase the capacity of the battery and make the structure compact, the electrodes can be composed of multiple plates connected in parallel. After the plates are stacked by an automatic wrapping machine to form a plate group, the plate group needs to be shaped when entering the next process so that the plate group can be more easily loaded into the mold.

[0003] Patent No. CN106935898A discloses a plate group shaping device. After the plate group is lifted to the shaping area by a cluster lifting device, the lifted plate group is shaped by a front-back shaping device and a side shaping device. After shaping, it is lowered back to the conveying device through a plate group lifting mechanism for conveying, and subsequent assembly processing is carried out, effectively improving the stability of plate group shaping.

[0004] After shaping, the plates need to be loaded into the mold. This device is placed on the conveying device for conveying after shaping to carry out subsequent assembly. During conveying, the conveying position cannot be effectively controlled, which is not convenient for subsequent mechanical grasping, affecting the assembly efficiency. And in the existing processing flow, shaping and assembly are carried out separately, with low efficiency, thus affecting the production efficiency. Summary of the Invention

[0015] 3. By setting the lower side of the shaping frame as an inclined surface in the present invention, the opening of the lower side of the shaping frame is increased, so that it is convenient for the electrode group to be stably inserted into the shaping frame, reducing the collision during the insertion process; and shaping blocks are arranged at the upper end inside the shaping frame, and the lugs of the electrode group are pinched by the shaping frame, thereby improving the shaping effect of the electrode group.

A conveying chain 2 is provided in the middle of the workbench 1. A blanking seat 3 is provided on the conveying chain 2. There is more than one blanking seat 3. The electrode group is positioned on the conveying chain 2 through being placed on the blanking seat 3 for conveying.

[0023] Clamping mechanisms are provided on both sides of the conveying chain 2. The clamping mechanisms include clamping plates 9 and clamping cylinders 10; the clamping cylinders 10 are symmetrically arranged on the workbench 1 on both sides of the conveying chain 2 respectively. The clamping plates 9 are connected to the output ends of the clamping cylinders 10. When the electrode group is conveyed to a fixed point position, the clamping cylinders 10 drive the clamping plates 9 to extend out to clamp and position the electrode group placed in the middle from both sides.

[0024] A slot is provided in the middle of the conveying chain 2. A top material mechanism is provided below the conveying chain 2. The top material mechanism includes a top material cylinder 7 and a top material plate 8; the top material cylinder 7 is arranged below the conveying chain 2. The top material plate 8 is connected to the output end of the top material cylinder 7; after the clamping plates 9 clamp the electrode group, the top material cylinder 7 drives the top material plate 8 to jack up. The top material plate 8 passes through the conveying chain 2 through the slot and contacts the electrode group, and jacks up the electrode group. The electrode group is guided to move upward by the clamping plates 9 on both sides.

[0025] A top plate 4 is provided on the upper side of the workbench 1. A slide rail 5 is provided on the lower side of the top plate 4. A shaping frame 6 is slidably arranged on the slide rail 5. There are two shaping frames 6. The shaping frames 6 are respectively driven by motors to slide at the end parts of the slide rail 5. By setting two shaping frames 6 to switch back and forth for work, the production efficiency is improved; the shaping frame 6 is driven by a motor to move above the blanking seat 3. The electrode group is jacked out by the top material plate 8 and inserted into the shaping frame 6 along the guiding action of the clamping plates 9. The inner side of the lower end of the shaping frame 6 is a slope, which is convenient for the stable insertion of the electrode group; a shaping block 13 is provided in the middle of the upper side inside the shaping frame 6. The shaping block 13 is of an oblique angle structure. The shaping block 13 pinches the lugs at the upper end of the electrode group, thereby improving the shaping effect of the electrode group.

[0026] Feeding mechanisms are provided on both sides of the upper end of the shaping frame 6. The feeding mechanisms include a feeding cylinder 11 and a feeding plate 12. The feeding cylinder 11 is arranged on the upper side of the shaping frame 6, and the feeding plate 12 is arranged on the upper inner side of the shaping frame 6. The output end of the feeding cylinder 11 passes through the shaping frame 6 and is connected to the feeding plate 12. Assembly seats 14 are provided on the workbench 1 corresponding to both ends of the slide rail 5, and molds are placed on the assembly seats 14. After the electrode group is inserted into the shaping frame 6, the motor drives the shaping frame 6 to move above the assembly seat 14. The feeding cylinder 11 drives the feeding plate 12 to extend downward, and the feeding plate 12 pushes the electrode group out of the shaping frame 6 and inserts the electrode group into the mold placed on the assembly seat 14, thus completing the assembly process of the electrode group, integrating the shaping and assembly of the electrode group together, improving the shaping and assembly efficiency of the electrode group, and thus improving the production efficiency.

[0027]

[0027] In actual production, the electrode groups are inserted into different feeding seats 3 one by one in sequence by a robotic arm, and then conveyed by the conveying chain 2, so that the electrode groups are positioned and conveyed through the feeding seats 3. When the electrode groups are conveyed to the fixed-point position, the clamping cylinders 10 on both sides drive the clamping plates 9 to extend, clamp the middle electrode groups from both sides, and shape the sides of the electrode groups; the lower ejector cylinder 7 drives the ejector plate 8 to extend upward, the ejector plate 8 passes through the slot and contacts the electrode plate, and pushes the electrode plate upward from the lower side. The electrode plate moves upward along the guides of the clamping plates 9 on both sides, and the electrode group is inserted into the upper shaping frame 6 for shaping. The shaping blocks 13 at the upper end inside the shaping frame 6 pinch the ears of the electrode group, causing the electrode ears to bend along the oblique angle direction of the shaping blocks 13. After the electrode group is inserted into the shaping frame 6 for shaping, the shaping frame 6 is driven by the motor to move above the assembly seat 14, and the feeding cylinder 11 drives the feeding plate 12 to push downward. The feeding plate 12 pushes the electrode group out of the shaping frame 6 and inserts the electrode group into the mold placed on the assembly seat 14, thus completing the assembly operation of the electrode group. By integrating the shaping and assembly of the electrode group together, the shaping and assembly efficiency of the electrode group is improved, and thus the production efficiency is improved.
