Background
The tight assembly by adopting a glass fiber separator (AGM) is one of the key technical requirements for manufacturing the valve-regulated lead-acid storage battery. Generally, the assembly pressure of the battery pole group is too low, so that the premature expansion and falling of the positive active substance can be caused, and the cycle life of the battery is poor; and if the assembly pressure is too high, acid is difficult to add, and acid at the central part of the polar plate is difficult to soak, so that dendrite short circuit is easy to generate, and the micro short circuit failure of the battery is caused. In the actual production process of the battery, the pressure fluctuation of the assembly of the pole group is large due to the influence of the deviation of the thickness of the partition plate and the thickness of the pole plate, and the consistency of the performance and the service life of the valve-regulated lead-acid storage battery is seriously influenced.

Detailed Description
The invention is further described with reference to specific examples.
The invention provides a lead-acid storage battery manufacturing device which comprises a pole plate curing device (not shown in the figure), a pole plate wrapping device (not shown in the figure), a pole group groove entering device (not shown in the figure) and a tabletting device for flattening wrapped pole plates output by the pole plate wrapping device.
As shown in fig. 1 and 2, the tabletting device of the present invention comprises an upper pressing wheel 4 and a lower pressing wheel 8, and the size, material and rotation speed of the upper pressing wheel 4 and the lower pressing wheel 8 are preferably the same, so as to ensure accurate pre-pressing when a single plate group passes through the pressing wheel gap, and improve the consistency of the assembly pressure of the AGM battery. Go up pinch roller 4 and down the clearance between the pinch roller 8 and can suitably adjust according to the thickness of the plate, thereby can carry out the pre-compaction to the monolithic utmost point crowd of difference, go up the epaxial bearing frame 5 that is connected with at pinch roller 4 both ends, bearing frame 5 and clearance accommodate the lead screw 6 are connected, clearance accommodate the lead screw 6 and pass pinch roller fixed bolster 7, in order to fix pinch roller 4, and can rotate from top to bottom, in order to adjust pinch roller 4's high position, specific interval control range can calculate according to the baffle compression ratio of different battery designs. The lower pinch roller 8 is fixed on the equipment. In addition, for achieving better prepressing effect, the upper pinch roller 4 and the lower pinch roller 8 are preferably rubber pinch rollers, the wrapping pole plate has a thickness A, a gap formed between the upper pinch roller 4 and the lower pinch roller 8 has a thickness B, and the difference between the thickness B and the thickness A is preferably less than 0.5 mm.
The manufacturing method of the lead-acid storage battery comprises the steps of pole plate solidification, pole plate wrapping and pole group entering, and after the pole plate wrapping step, the method also comprises the step of tabletting the wrapped pole plates. The pole plate wrapping device wraps an AGM separator 2 on the upper surface and the lower surface of a pole plate 1 to form a wrapping pole plate 3 with three surfaces wrapped and one open surface, and the wrapping pole plate 3 comprises a bottom end wrapped by a diaphragm and a top end not wrapped by the diaphragm. The tabletting process is as follows, the tablet-coated polar plate 3 passes through the horizontal conveying belt, the bottom end coated by the diaphragm firstly enters the gap between the upper pressing wheel 4 and the lower pressing wheel 8, and the top end not coated by the diaphragm enters the gap, as shown in the X direction in the figure. While passing through the gap, the AGM separator 2 is pre-compressed, so that the thickness uniformity of each of the wrapped polar plates 3 is improved, and then the thickness uniformity of a battery pole group consisting of a plurality of wrapped polar plates 3 and the uniformity of the pole group assembly pressure are also improved.
The assembly pressure of the pole group is not only influenced by the thickness variation of the partition plate, but also influenced by the thickness of the pole plate. According to the technical scheme, the polar plate and the partition plate are wrapped into the single-piece polar group, and then the single-piece polar group is pre-pressed, so that the consistency of the assembly pressure of the polar group can be obviously improved.
The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the spirit of the invention as set forth in the claims.
