Abstract

PURPOSE:To enable a complex grid base plate to be manufactured through almost the same process as that of a lead or lead alloy base plate by supplying and attaching horizontal synthetic-resin crosspieces between the formation work and the punching work of the base plate. CONSTITUTION:A base plate consisting of a rectangular frame 1 and a number of vertical crosspieces 2 formed inside the frame 1, is prepared by forming and punching a lead or lead alloy plate by press work. Between the formation work and the punching work, a number of horizontal synthetic-resin crosspieces 3 are supplied parallel to each other before they are attached to the frame 1 and the vertical crosspieces 2. In attaching the horizontal crosspieces 3, concave sections 4 are formed on the frame 1 and the vertical crosspieces 2 crossing the horizontal crosspieces 3 in the formation work, then the supplied horizontal crosspieces 3 are introduced on the concave sections 4 between the formation work and the punching work, followed by attaching the horizontal crosspieces 3 to the frame 1 and the vertical crosspieces 2 by pressure fixation, fusion, adhesion or the like. After that, in the punching work, the horizontal crosspieces 3 are punched to be the same size as the width of the frame 1 or protrude from the frame 1.

Description

[Detailed Description of the Invention] The present invention is a combination of a lead or lead alloy lattice board (hereinafter referred to as that board) with crosspieces formed in a rectangular frame and a synthetic resin board. Composite for storage battery (15-year board (hereinafter abbreviated as composite board), so it is made of a normal board that is especially press-processed) was bonded with a C1 synthetic resin crosspiece in the process. We provide a composite substrate that can be manufactured at a low cost using a process that is almost the same as manufacturing a culm.

Recent inscription (Yoj (1 alloy 1y2 gnat 1: Yu within my limit), 141 or lead alloy manufacturing cost, Z, , Δ・1koj: l
:, lFj LX I・:Niyō": A composite board bonded to A at 911 u℃ has been proposed. It is made of resin (1) which improves the strength of the substrate and improves the retention of the active material paste i~, and it is possible to obtain an electrode for a storage battery with an eaves ω and lζ16 performance.

However, in this composite board, a board with a margin formed in a rectangular frame and a synthetic resin board are each made in separate pieces, and these are combined to produce a ZC composite board. Therefore, the manufacturing cost is high, and the manufacturing cost is high, so it is necessary to create a lightweight and high-performance storage battery battery (~/J1'B?, regardless of whether it is used for special purposes). It has not been used for a long time.

In view of this, in order to reduce production costs, as a result of various tests, the present invention has developed an A3
We have developed a composite board that can be manufactured at low cost by supplying synthetic resin crosspieces and gluing them together to create a composite board. In a composite board in which 4 synthetic 4&I resin boards are combined and bonded to a board with a crosspiece formed inside,
A recess is formed in the frame and the vertical crosspiece that intersect with each other, and a recess is formed in the frame and the vertical crosspiece, and a part or all of C1 is parallel to each other. It is characterized in that a horizontal beam made of synthetic resin that is equal to Ill or that protrudes from the substrate is inserted and bonded.

That is, the composite board of the present invention has a rectangular frame <1> and a plurality of hits in the frame (1), as shown in FIGS.
((2) is formed by forming and punching from a lead or lead alloy plate by normal press working, and this forming process I
Multiple synthetic resin horizontal bars (3) between I and 4■Nukikacho
are supplied in parallel, horizontal F1<3) is connected to frame (1) and 4i
l (4-! It is glued to (2).Horizontal crosspiece (33)
For adhesion, a recess (4) is formed in the frame (1) intersecting the horizontal a (3) and the vertical +1 (2) during the molding process, and between the molding process and the 1] punching T, Ill, The supplied horizontal +i (3) is introduced into the four parts (/I), and the horizontal I1 (3) is adhered to the frame (1) and the vertical beam (2) by pressure bonding, fusion, adhesion, etc. In the punching process, horizontal 1 = ship (3) and frame (1) I
It is equal to ll or subtracts 1 so that it is 11 more than the frame (1).

There are no particular restrictions on the cross-sectional shapes of the rectangular frame (1), vertical (2) and horizontal +1 (3). As shown in Figures (A) and (S), the cross-sectional shape is formed into a convex shape, and four sections are formed at the L part that intersects with the horizontal +I (3). In addition to facilitating the introduction of <3), the frame (1)
) and vertical ti (2), it is desirable to improve the adhesive strength of the horizontal bar (3) without increasing the strength of the horizontal bar (3). It is preferable to form a rectangular or hexagonal shape and form appropriate protrusions on its outer periphery to enhance retention of the active material base.Furthermore, one or both of the vertical bars (2) and horizontal bars (3) may be folded in a staggered manner. By bending, it is possible to further improve the retention of the live material v1 paste. For example, as shown in Figure 3 (a), the horizontal bar (3) attached to the vertical bar (2) can be bent in a staggered manner and bonded. Alternatively, each of the vertical bars (2) and horizontal bars (3) may be bent into a 5" island shape and bonded as shown in FIG. 3(B).

In addition, we have described a composite board in which 1; [11] are formed in 16 rows within a rectangular frame, and all of the horizontal bars are made of synthetic resin. If so, the frame and vertical bars may be shaped like 04 or 04, or shaped like an urinary shape -b, as long as they can be formed by press or punched. For example, as shown in Figure 4, box (1) tj7! Vertical +1 from the corner (
2) is formed into a release shape, and horizontal F1 <
By adhering 3), current collection efficiency can be increased. In addition, as shown in Fig. 5, some of the horizontal bars (5) and vertical bars (2) are integrated within the frame (1). You can glue the crosspiece (3).

Also, even if both ends of the synthetic 1f, I resin crosspiece (3) protrude from the frame (1) as shown in the figure, since the horizontal crosspiece (3) is an insulator, what kind of support does it have? - There is no. Also, Fig. 1, 4
As shown in the figure and Fig. 5, the position of the hole (6) should be determined by press forming or punching T, or if possible, in which position. good.

According to the present invention, the plate consists of the following 114 components, and in the normal process of press-working a lead or lead alloy plate to form and punch the board, forming and punching the board. By providing a supply part and an adhesion part of the synthetic resin horizontal crosspiece between the board and the board, it is possible to manufacture the board in a process that is almost the same as that of the lead or 1(2) alloy board, and it can be manufactured at a low cost. Wear. In addition, the composite group of the present invention (k is reinforced and lightened by a synthetic resin crosspiece as in the conventional case and retains the active material base 1-1) 1
It is also highly effective and can be used as a high-performance electrode for storage batteries.
