Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to an improved mechanism for riveting battery caps. Background Technology

[0002] The battery cap is an important component of a battery; it provides a sealed function and acts as a safety valve, such as... Figure 1 As shown, the battery cap 100 is typically composed of a top cover 101, an insulating ring 102, a sealing ring 103, and a rigid terminal 104. The top cover 101 serves to provide a positive conductive terminal, and the sealing ring 103 is disposed inside the top cover 101 and located between the rigid terminal 104 and the bottom plate of the top cover 101. The traditional riveting mechanism includes a roller seat 1', a roller shaft tube 2', a roller shaft 3', and two riveting rollers 4'. The upper end of the roller shaft tube 2' is fixed on the roller seat 1', and the middle part of the roller shaft 3' is vertically fixed to the lower part of the roller shaft tube 2'. The two riveting rollers 4' are rotatably sleeved on both sides of the roller shaft 3' via bearings. During assembly, the top cover 101 needs to be pressed by the riveting mechanism to assemble the insulating ring 102, sealing ring 103, hard pole 104, etc. together. The riveting rollers 4' apply pressure to the sealing ring 103 through the top cover 101's snap edge, the insulating ring 102, and the hard pole 104. Since the insulating ring 102 is made of ceramic material, it is easy to break if the pressure is too high, which affects the yield. Utility Model Content

[0003] The purpose of this utility model is to provide an improved riveting mechanism for battery caps with adjustable riveting roller height and high yield.

[0004] To achieve the above objectives, the technical solution of this utility model is:

[0005] This utility model discloses an improved mechanism for riveting battery caps, comprising a base, an upper seat, a guide rod, a pressure rod, a central shaft tube, a synchronous wheel, a synchronous bearing, a roller seat, a roller shaft tube, and a riveting roller;

[0006] The base is fixedly installed on the lifting mechanism. The upper end of the guide rod is fixed on the upper seat, and the lower end of the guide rod is movably inserted through the base. The upper part of the pressure rod is screwed to the upper seat, and the middle part of the pressure rod is movably inserted through the central shaft tube. The lower part of the pressure rod passes through the roller shaft tube and then passes through the riveting roller. The lower end of the pressure rod can abut against the battery cap. The upper part of the central shaft tube is fixedly inserted through the base. The synchronous wheel is rotatably sleeved on the central shaft tube through the synchronous bearing. The top surface of the roller seat is fixed to the bottom surface of the synchronous wheel, and the bottom surface of the roller seat is fixedly connected to the riveting roller through the roller shaft tube.

[0007] The pressure rod consists of an adjusting rod, an adjusting rod, and a positioning rod, which are sequentially and fixedly connected together. The adjusting rod is screwed onto the upper seat, the adjusting rod is movably inserted into the central shaft tube, and the positioning rod passes through the roller shaft tube and then into the riveting roller, with the lower end of the positioning rod able to abut against the battery cap.

[0008] The riveting roller includes two roller bushings, two fixing screws, two rollers, and riveting bearings; the two roller bushings are respectively vertically fixed to both sides of the roller shaft tube by fixing screws, and the two rollers are respectively rotatably sleeved on the roller bushings by riveting bearings; the inner side of the roller has notches for forming.

[0009] There is a handle at the top of the lever for rotating the lever.

[0010] By adopting the above solution, this utility model has the following advantages:

[0011] 1. Because this utility model adds a pressure rod at the center of the mechanism, it directly compresses the sealing ring through the hard pole, which solves the problem of insufficient force transmission of soft structural parts, avoids damage to the insulation ring, and has a high yield.

[0012] 2. The upper part of the pressure rod of this utility model is screwed to the upper seat, and the height of the pressure rod can be adjusted up and down, thereby adjusting the height of the riveting roller, which solves the problem that the edge of the riveting top cover becomes thinner as the compression ratio of the sealing ring increases (the riveting pressure increases).
