Description

A welding tool for casting and welding round terminals of lead-acid batteries

technical field

The utility model relates to the field of lead-acid batteries, in particular to a welding tool for casting and welding round terminals of lead-acid batteries.

Background technique

Lead-acid battery is the most common type of secondary battery. It is popular due to its stable voltage and low price. Lead-acid battery consists of tubular positive plate, negative plate, electrolyte, separator, battery tank, battery cover, pole Column, liquid injection cover and other components. At present, my country's lead-acid battery production forms are divided into three types: 1) lead-acid battery manufacturing; 2) plate production; 3) battery assembly; most manufacturers focus on battery assembly, and the specific process includes clapboard--electrode group welding --Case loading--Upper cover sealing--Terminal welding--Into tank--Acid injection--Formation--Cleaning--Storage---Packing and delivery, terminal welding is the last step of battery case processing , is also one of the most critical steps, the welding performance of the terminal will directly determine whether it can be discharged with a large current and the service life of the battery. The terminal welding of the battery refers to the process of forming the positive and negative output terminals at the designated position of the battery with welding torch, terminal mold (ferrochrome and formed end pieces for small sealed batteries) and prefabricated lead-based alloy electrodes. At present, manual welding is still the main method of terminal welding, although in recent years, casting welding machines have also been used for automatic casting welding, such as Chinese utility model patent CN201220509934.4, which provides a terminal feeding device for battery terminal welding. It can help to realize the fully automatic welding process and improve the welding efficiency, but it is prone to quality problems such as low cast welding pass rate or false welding.

The quality of manual welding is greatly affected by the experience and skills of personnel. The capacity of the separator is burned, the surface of the bus bar is uneven, and there are defects such as slag, burrs, false welding, and inconsistent welding. In order to reduce the influence of artificial factors, it is particularly important to design fixtures with excellent performance. Although some tools and fixtures have appeared at present, the design is too complicated, so that the use process is still inconvenient to operate. Although the Chinese utility model patent CN200420103627.1 proposes a simple and easy-to-operate electrode terminal welding tool, the nickel foam battery is quite different from the lead-acid battery.

Utility model content

The utility model provides a welding tool for casting and welding round terminals of lead-acid batteries with excellent performance and can improve the consistency of lead-acid batteries.

In order to solve the problems existing in the prior art, the technical scheme adopted by the utility model is as follows:

A welding tool for casting and welding round terminals of a lead-acid battery, comprising a comb slider, a bead, a bead fixing plate, a handle, a connecting rod, a slideway plate, a pillar, a battery tank and a base plate, the battery tank is located above the base plate, and the The comb slide block is connected with the handle through the connecting rod, the slideway plate is installed on the handle bar of the handle, and the slideway plate is installed above the bottom plate through a pillar.

Further, there are two symmetrical handles.

Further, the comb sliders are divided into two groups with left and right symmetry.

Further, there are two symmetrical bezels, and the bead fixing block is located in the middle of the two beading bars.

Further, there are two symmetrical slideways.

First put the battery after casting and welding into the battery slot, then snap the lugs at the two column heads into the corresponding slots of the slider of the comb plate, install the bead and clamp it tightly, and place the silver-plated round terminals on the slider of the comb plate respectively At the position of the stigma, use acetylene lead strips to weld firmly. After welding, open the handles on both sides upwards. The handles are connected to the sliders of the comb boards with connecting rods, move the sliders of the comb boards to the outside, and remove the batteries directly by hand. That's it.

Compared with the prior art, the utility model has the following advantages: 1. Simple and convenient use, high processing efficiency, saving labor costs, and improving economic benefits; 2. Good consistency of processed products and low probability of false welding; 3. Welded terminals The firmness is more guaranteed, the battery is more durable, the discharge performance is good and the service life of the battery is greatly extended.

detailed description

Now in conjunction with accompanying drawing and embodiment the utility model is described further.

A welding tool for casting and welding round terminals of a lead-acid battery, comprising a comb slider 1, a bead 2, a bead fixing plate 3, a handle 4, a connecting rod 5, a slideway plate 6, a pillar 7, a battery tank 8 and a bottom plate 9, The battery slot 8 is located above the base plate 9, the comb slider 1 is connected to the handle 4 through the connecting rod 5, the slideway plate 6 is installed on the handle bar of the handle 4, and the slideway plate 6 is installed above the bottom plate 9 through the pillar 7.

There are two left-right symmetrical handles 4, and two left-right symmetrical comb sliders 1.

The said bead 2 is two left and right symmetrical, and the said bead fixing block 3 is located in the middle of the two bead 2 .

Described slide way plate 6 is left and right two.

The utility model is especially suitable for welding the silver-plated round terminals of 2*3 type lead-acid batteries, and the specific usage method is as follows:

First put the cast-welded battery into the battery slot 8, then snap the lugs at the two column heads into the corresponding slots of the slider 1 of the comb plate, install the bead 2 and fasten it, and place the silver-plated round terminals on the comb plate respectively. The position of the column head of the slider 1 can be welded firmly with an acetylene lead strip. After welding, open the handle 4 on both sides upward, and the handle 4 uses the connecting rod 5 to connect the slider of the comb. Move outside, just move the battery out by hand.
