Description

Technical Field

[0001] This invention relates to the field of battery manufacturing, and in particular to a battery terminal perpendicularity inspection tool. Background Technology

[0002] In the battery manufacturing process, the welding process—joining the positive and negative terminals and plates together—is particularly important. The perpendicularity of the positive and negative terminals after welding is a crucial indicator of weld quality and directly affects subsequent battery manufacturing processes. Current technical standards require a perpendicularity deviation of ±2mm for the terminals to be considered acceptable. In the current production process…

[0003] Often, the degree of misalignment of the positive and negative terminals needs to be observed visually. If the terminals are misaligned, they are manually adjusted to the center using an awl or other tubular object. The inspection process after adjustment is still done manually by workers. The inspector places a cover on the battery compartment, exposing the terminals through the cover. At this point, the inspector uses calipers to manually inspect the terminals. This inspection process has the following problems: 1. It is difficult to find a reference point with calipers, resulting in a large inspection error; 2. The inspector relies entirely on visual observation, making it difficult to distinguish millimeter-level errors. Even if the error exceeds the tolerance range of ±2mm, it is difficult to make a judgment of non-compliance. Summary of the Invention

[0004] The main objective of this invention is to provide a battery terminal perpendicularity gauge, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a battery terminal perpendicularity gauge, comprising a reference ring and an offset scale, wherein an offset ring is provided inside the reference ring, and rotating shafts are provided on both sides of the outer arc surface of the offset ring, and the offset ring is rotatably connected to the reference ring through the rotating shafts. The offset scale includes a fixed part and an offset part, wherein the fixed part is provided on the top surface of the reference ring, and the offset part is provided on the top surface of the offset ring.

[0006] Furthermore, the offset scale fixing part includes a reference bracket fixed on the top surface of the reference ring. The reference bracket has a certain height and a reference line is taut at its top. The reference line is located directly above the rotating shaft and parallel to the rotating shaft.

[0007] Furthermore, the offset scale offset part includes an offset bracket fixed on the top surface of the offset ring. The height of the offset bracket is slightly lower than that of the reference bracket. An offset line is taut at the top of the offset bracket. The offset line is located directly above the rotating shaft and parallel to the rotating shaft.

[0008] Furthermore, at least one end of the offset line is provided with an offset scale plate, the offset scale plate is fixed on the offset bracket, and the scale bars on the offset scale plate are evenly distributed on both sides of the offset line and parallel to the offset line.

[0009] Furthermore, both sides of the rotating shaft are provided with limiting protrusions.

[0010] Preferably, the reference line is made of steel.

[0011] Preferably, the offset line is made of steel.

[0012] Preferably, the reference ring is a circular ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This invention comes with a reference ring. When using it, simply place the reference ring on the surface of the battery top cover to complete the setting of the reference point, which is quick and convenient.

[0015] Second, in this invention, there are offset lines and offset scale plates. The offset lines can amplify the degree of tilt of the pole, while the offset scale plates can accurately display the offset amount, thus avoiding the problem of insufficient accuracy of visual observation.

[0016] Third, the present invention has a simple structure, is easy to carry, and can achieve flexible and rapid detection. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figure 1As shown, a battery terminal perpendicularity gauge includes a circular reference ring 1 and an offset scale. An offset ring 2 is located inside the reference ring 1, and rotating shafts 3 are located on both sides of the outer arc surface of the offset ring 2. Each rotating shaft 3 has a limiting protrusion 9. The offset ring 2 is rotatably connected to the reference ring 1 via the rotating shafts 3. The offset scale includes a fixed part and an offset part. The fixed part is located on the top surface of the reference ring 1, and the offset part is located on the top surface of the offset ring 2. The fixed part includes a reference bracket 4 fixed to the top surface of the reference ring 1. The reference bracket 4 has a certain height and a steel reference line 5 is taut at its top. The reference line 5 is located directly above and parallel to the rotating shaft 3. The offset part includes an offset bracket 6 fixed to the top surface of the offset ring 2. The offset bracket 6 is slightly lower than the reference bracket 4, and a steel offset line 7 is taut at its top. The offset line 7 is located directly above and parallel to the rotating shaft 3. The offset line 7 has an offset scale plate 8 at at least one end. The offset scale plate 8 is fixed on the offset bracket 6, and the scale bars on the offset scale plate 8 are evenly distributed on both sides of the offset line 7 and are parallel to the offset line 7.

[0021] It should be noted that the working principle of the battery terminal verticality gauge of the present invention is as follows: Holding the reference ring 1, the offset ring 2 is slowly placed on the terminal. During placement, the reference ring 1 needs to be slowly rotated to find the offset direction of the terminal. Once the offset direction is found, the offset ring 2 can be placed to the bottom of the terminal, wherein the offset bracket 6 is slightly higher than the normal height of the terminal. At this time, the reference ring 1 is placed on the top cover of the battery to provide a measurement reference point. If the terminal is tilted, the offset ring 2 will also tilt accordingly. At this time, the initially overlapping reference line 5 and offset line 7 will be misaligned when viewed from above, indicating that the terminal is tilted. At the same time, the offset scale plate 8 can also display the degree of misalignment, that is, the amount of tilt of the terminal, which is convenient for the staff to make fine adjustments to the terminal.

[0022] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
