Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid batteries, and in particular relates to a device for detecting the quality of a through-wall welding hole of a lead-acid battery. Background Art

[0002] Lead-acid batteries are generally used as batteries for starting cars. The structure of lead-acid batteries mainly includes a battery slot, a battery cover, a pole group and an electrolyte in the battery slot. The battery slot is generally provided with multiple cells, each of which is provided with a pole group. Adjacent pole groups are connected in series. When connected in series, in a production process of lead-acid batteries, holes are punched on the partitions between the cells, and then the series-connected structure passes through the holes. In this way, the connection structure does not need to climb over the upper part of the battery slot, so that the space inside the battery cover does not need to be very large, saving battery space. This connection method is usually called through-wall welding.

[0003] The through-wall welding structure needs to be quality inspected. For example, the utility model with authorization announcement number CN206440691U discloses a lead-acid battery through-wall welding effect detection mold box, which includes a simulated battery shell with an open top, in which at least two vertically parallel simulated battery partitions are detachably fixed, and the simulated battery partitions are provided with through-wall welding holes. Bus positioning blocks that can move up and down are arranged between any two adjacent simulated battery partitions and between the outermost simulated battery partitions and the left and right side walls of the simulated battery shell, and each of the bus positioning blocks is threadedly connected to a vertically arranged adjusting screw, and the lower end of each adjusting screw is pivotally connected to the bottom wall of the simulated battery shell.

[0004] In addition, due to the size and position of the through-wall welding of the pole group, the lead parts may explode and the structural strength may be insufficient during through-wall welding, so it is necessary to detect the size and position of the through-wall welding hole. In the prior art, calipers are generally used for detection, but the internal cavity of the battery is too small to effectively and accurately detect the size, which poses a quality risk.

[0005] At the same time, with the increase of on-board electrical appliances, high current discharge is also getting higher and higher. The current battery manufacturers' wall-penetrating welding sizes range from φ10-φ16mm, and the battery slots are designed in 1×6 and 2×3 styles. If a separate testing tool is designed for each battery model, a lot of tooling will be needed. Utility Model Content

[0008] A crisscrossing slide groove is provided on one side surface of the detection plate, and the cross section of the slide groove is a T-shape with a larger inner side and a smaller outer side;

[0020] The lead-acid battery comprises a battery slot, the inner cavity of which is divided into a plurality of cells by a partition plate, each cell being provided with a pole group, and a through-wall welding hole is provided on the partition plate between adjacent pole groups, and when the positive and negative buses in adjacent pole groups are connected in series, they are connected by means of lead columns passing through the through-wall welding holes without climbing over the top surface of the partition plate.

[0021] like Figures 1 to 3 As shown, a device for detecting the quality of through-wall welding holes of lead-acid batteries includes a detection plate 1. The detection plate 1 is in the shape of a plate with a certain thickness as a whole. The detection plate 1 has a slot for straddling the detection plate 1 on the side wall of the lead-acid battery or on the partition plate when in use. The bottom of the slot (because the slot opens downward, the bottom of the slot is at the upper part of the detection plate 1) has a vertically arranged clamping portion 2. When in use, the clamping portion 2 is clamped with the side wall of the lead-acid battery or the partition plate. The slot has a horn 3 below the clamping portion 2 for easy use.

[0022] The card slot is arranged in the middle of the length direction of the detection board 1, and the card slot divides the detection board 1 into two parts. The same side surface of the two parts is provided with crisscrossing slide grooves 4, and the cross section of the slide groove 4 is a T-shaped one with a large inner side and a small outer side. The cross section of the slide groove 4 refers to the cross section of the surface of the detection board 1 where the slide groove 4 is located, so the inner side of the cross section of the slide groove 4 refers to the side away from the surface of the detection board 1, and the outer side is close to the surface of the detection board 1.

[0023] The device for detecting the quality of the through-wall weld hole of the lead-acid battery in the present application also includes a detection column 5, one end of which has a slider 6 that extends into the slide groove 4 and cooperates with the slide groove 4, and the other end of the detection column 5 is cylindrical and is used to extend into the through-wall weld hole during detection.

[0024] In a preferred embodiment, the slide grooves 4 are arranged vertically and horizontally, and the intervals between adjacent slide grooves 4 are the same. The slide grooves 4 on the two parts of the detection plate 1 are connected to each other and are used to detect the movement of the column 5.

[0025] In a preferred embodiment, the two parts of the detection board 1 are each equipped with a detection column 5. Each chute 4 of the two parts of the detection board 1 has at least one opening 7 extending to the edge of the surface of the detection board 1 for taking the detection column 5 into the chute 4.

[0026] The top of the detection board 1 is provided with an operating portion 8 extending along the length direction, so as to facilitate hand-held placement during use.

[0027] When the device for detecting the quality of through-wall welding holes of lead-acid batteries of the utility model is used, the detection column 5 is first moved to a suitable position, and then the detection plate 1 is straddled on the side wall or partition plate of the lead-acid battery. When straddling, the length direction of the detection plate 1 is perpendicular to the side wall or partition plate of the lead-acid battery to be straddled. Whether the size and position of the through-wall welding hole are qualified can be judged by whether the detection column 5 can smoothly extend through the through-wall welding hole. If it is unqualified, the punching machine needs to be adjusted to obtain a lead-acid battery with a qualified through-wall welding hole.
