Description

TECHNICAL FIELD

[0001] The utility model relates to a battery production technical field, specifically relates to a lead -acid battery busbar connecting bridge detection frock. BACKGROUND

[0002] At present, valve regulated sealed storage battery is applied increasingly at home and abroad, and the voltage value of storage battery is gradually expanded to 2V, 6V, 8V, 12V and the like in consideration of the application environment and range of storage battery, and the expansion of voltage value is realized by the series connection of 2V single body in storage battery through bridge welding and wall welding and the like. The existing lead-acid battery generally comprises a battery tank and a plurality of pole groups arranged in the battery tank, and the single-pole group is composed of positive and negative plates, a separator and a busbar for welding the plates, and the adjacent pole groups are connected by a connecting bridge to enable all the pole groups to be connected in series.

[0003] The patent document with the authorized announcement number CN203013836U discloses a single body connecting bridge of tubular gel storage battery, two polar columns are added at both ends of the busbar, the polar columns are welded with the busbar when the busbar is welded, the two polar columns are clamped by welding pliers after the single body is enclosed, and the connecting bridge is formed after welding. The height of the connecting bridge is greater than that of the busbar, and the connecting position is higher than the center separator of the battery tank to realize the connection of adjacent single bodies.

[0004] In the prior art, the busbar and the connecting bridge of a plurality of pole groups installed in the same battery tank are welded at the same time. In order to facilitate the demolding of the busbar, the connecting bridge is arranged on the side surface of the busbar, and the connecting bridge is straightened by the corresponding mold when the pole group is inserted into the tank, but the following problems exist.

[0005] (1) When the mold is not installed in place or the pushing force is not enough, the connecting bridge cannot be straightened, and the connecting bridge is stuck on the center separator, causing the connecting bridge to be damaged.

[0006] (2) When the mold pushing force is too large, the connecting bridge is straightened, and cracks occur at the bent part of the connecting bridge. During the use of the storage battery, the cracks are corroded by sulfuric acid electrolyte, causing the connecting bridge to break.

[0007] (3) When the height of the connecting bridge is too high, the battery cover cooperated with the battery tank is difficult to be buckled in place, and the connecting part is easy to be separated during the sealing of the battery tank cover, so that rework is needed, affecting the work efficiency.

[0008] Therefore, it is necessary to detect whether the connecting bridge is installed in place before assembling the storage battery, so that the mold pushing and the size of the connecting bridge can be adjusted in time, and the qualified rate of the storage battery product is improved.

[0009] The patent document with the publication number CN205843519U discloses a lead storage battery busbar connecting bridge detection tool, which comprises a detection plate, the detection plate is a rectangular plate with at least one plane and has two mutually parallel edges. A back plate is vertically arranged on one plane, the outer side surface of the back plate is flush with one side edge of the detection plate, and the back plate is parallel to the other side edge. The detection plate and the back plate are integrally formed and have an inverted L shape. A plurality of notches matched with the connecting bridge are arranged on the edge away from the back plate, and all the notches are on the same straight line. The size and shape of all the notches are matched with the correctly installed connecting bridge, and the height of the connecting bridge is uniform and the same. When the tool is applied to the detection of the connecting bridge of the busbar of the storage battery, the inner side surface of the back plate abuts against the outer side surface of the battery groove, the plane of the detection plate abuts against the groove opening of the battery groove, and the connecting bridge is distributed in the notches. When the inner side surface of the back plate and the outer side surface of the battery groove and the plane of the detection plate and the groove opening of the battery groove are in complete contact, and the connecting bridge is matched with the notches, it is determined that the product is qualified.

[0010] The detection tool can only detect the connecting bridge on one side, and mainly relies on the naked eye observation of the detection personnel to determine whether the connecting ball is qualified during the detection of the connecting bridge, and errors are prone to occur during the detection process.

[0029] Example 1: Refer to Figures 1-3As shown, a kind of lead storage battery busbar connecting bridge detection tool, including frame 1, the inside of the frame 1 is provided with the accommodation slot 2.

[0030] The left and right sides in frame 1 are both provided with a plurality of grooves 3, and the groove 3 corresponds to the connecting bridge 10 on the battery, and the lower end of the frame 1 is fixed with the limiting plate 7.

[0031] The frame 1 on one side of the groove 3 is fixed with the inverted U-shaped support 4, one vertical part of the support 4 is fixed on the frame 1, the flat part of the support 4 is located above the groove 3, the other vertical part of the support 4 is located in the frame 1 and corresponds to the internal space of the groove 3, and the lower end of the flat part of the support 4 is fixed with the upper distance measuring instrument 5, which corresponds to the groove 3, and the vertical part of the support 4 in the frame 1 is fixed with the lower distance measuring instrument 6 on the side facing the groove 3, which corresponds to the groove 3, and the upper distance measuring instrument 5, the controller, the power supply and the first buzzer are electrically connected. The lower distance measuring instrument 6, the controller, the power supply and the second buzzer are electrically connected
