Description

Process for combining pole groups into the outer casing

The present invention relates to a process for combining pole groups into an outer casing, and in particular, the process can make the combined work faster, the production line more streamlined, and take up less space.

The structure of the battery is generally arranged in the outer casing of the plurality of plates, and the plates are connected by a bridge so that the pole groups can be electrically connected. Conventionally, the way in which the bridge is placed on the pole plate is a technique commonly referred to as "fusible", in which a molten metal is injected into a cavity of a mold having a bridge shape, and then the pole is The poles of the plurality of plates included in the group are inserted into the respective cavities, waiting for a fixed time to solidify the molten metal and then fixed to the tabs, and after the mold body and the pole group are separated (released), the battery pole group is completed. The casting work of the bridge. After the pole group is welded to the bridge, it is taken out and placed in the battery casing.

The first figure shows a schematic diagram of a conventional production line that combines a pole group with a casing and its process. As shown in the flow direction of the arrow in the figure, first, the staff puts a plurality of polar plates in the A area into the jig to form a pole group in the A area. After the finishing is completed, the staff operates the machine equipment to the pole group. Press into the iron letter. The C area is the casting area, the mold cavity of the mold is injected into the molten metal in this area; the iron core after the completion of the indentation in the B area is transported to the C area, and the iron and the mold are embedded by the staff. In order to insert the tab into the cavity, the mold and the iron core are conveyed in the C1 area for a while to wait for cooling. After reaching the D area, the molten metal is cooled to form a bridge, and the worker will be in the D area. The bridge is separated from the mold (release), and then the pole group and the iron core are transported to the E area. The staff members push the pole group out of the iron core in the E area; the pole group after the iron core is ejected is Delivered to the F area, the worker loads the pole group into another fixture and transports it to the G area, where the staff presses the pole group from the fixture into the empty battery casing.

According to the conventional combination process of the pole group and the battery casing, the production line is very long, and each work area needs to be equipped with a staff member, resulting in high production cost.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a process for effectively shortening a production line in which a pole group is combined with a battery casing, thereby simplifying equipment and workers and reducing manufacturing costs.

The feature of the present invention is to simplify the conventional steps of combining the pole group into the battery casing, but does not affect the process of combining effects; firstly, the plurality of plates are arranged into a pole group by using a jig, and then a part of the pole group is directly pressed. Into a battery case, the other part exposes the outer casing, and then the exposed ear of the outer casing is subjected to the process of unraveling and flattening, then the flux is adhered and dried, and then the outer casing is fitted with the mold to make the ear Inserting into the cavity of the mold mold into which the molten metal has been injected, waiting for the molten metal to cool and welding to the pole to form a bridge, then detaching the bridge from the mold, and finally pressing the pole group completely into the outer casing, that is, Complete assembly of the pole group and the outer casing.

Based on this, the process provided by the present invention includes:

(a) placing a pole plate having a tab in a jig to form a pole group;

(b) pressing a portion of the pole group after finishing into a casing, and exposing the casing to another portion;

(c) processing the tabs of the pole group placed in the outer casing, and adhering the flux to the tabs and drying them;

(d) inserting the tabs of the pole group that have been placed into the outer casing into the cavity of the mold mold into which the molten metal has been injected, and fitting the outer casing to the mold;

(e) waiting for the molten metal to cool and soldering to the tab to form a bridge, and then detaching the bridge from the mold;

(f) Fully pressing the pole group exposing the outer casing into the outer casing.

Preferably, in the present invention, three quarters of the height of the pole group is pressed into the outer casing, and the other quarter is exposed to the outer casing. During the operation, the outer casing is clamped by the mechanical arm, and the ear is inserted. The mold cavity of the mold.

In the present invention, by directly pressing the pole group into the battery casing and welding the tabs provided in the casing directly to the mold, it is possible to omit the conventional procedure of pressing the pole group into the iron core and then taking it out from the iron core. This simplifies the overall process, reduces staff and equipment expenses, and effectively reduces production costs.

The embodiments of the present invention will be described in more detail below with reference to the drawings and the <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt;

The second figure shows a production line and flow diagram of the invention in which the pole group is combined in the battery casing, which comprises a pole group finishing zone 1, a pole group pressing into the outer casing zone 2, a polar ear processing and welding zone 3, and a demolding zone. 4 and complete the combined area 5. In the first group of the production process of the group cleaning area, the staff uses the jig in this area to stack the plurality of pole plates 61 with the poles 611 into a pole group 6 (as shown in the third figure). The group 6 is transported by the conveyor to the pole group and pressed into the outer casing area 2, in which the worker presses the pole group 6 into a battery casing 7, so that a part of the pole group 6 enters the casing 7, and another portion including the tab 611 is exposed. The outer casing 7; in the embodiment of the invention, three quarters of the height of the pole group 6 is pressed into the outer casing 7, and the other quarter is exposed to the outer casing. After completion, it is conveyed to the tab processing and welding zone 3, in which the device processes, decompresses, and cuts the poles 611 of the pole group 6 placed in the outer casing 7 and applies the flux after the tab 611 is adhered to the flux. Drying; after drying, the housing is clamped by the robot arm, and the tab 611 of the pole group 6 placed in the outer casing 7 is inserted into the cavity 81 of the mold 8 into which the molten metal has been injected (see the fourth drawing). And fitting the outer casing 7 to the mold mold 8, waiting for the molten metal to cool and welding to the tab 611 to form the bridge 62, and then detaching the bridge 62 from the mold 8 in the demolding zone 4; The rear pole group is transported by the robot arm to the completion combination zone 5, and the pole group 6 is completely pressed into the battery casing 7 by the apparatus, and only the bridge 62 is exposed to the outer casing (refer to Fig. 5).

The above is only a preferred embodiment for explaining the present invention, and is not intended to limit the present invention in any way, and any modifications or alterations to the present invention made in the spirit of the same invention. All should still be included in the scope of the intention of the present invention.
