Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid battery detection, and in particular relates to a measuring instrument for detecting the flatness of a lead-acid battery plate. Background Art

[0002] The structure of a lead-acid battery includes a battery tank and a pole group arranged in the battery tank. The pole group includes positive plates and negative plates arranged at intervals. The positive plates and negative plates are separated by a partition. The pole group is tightly assembled in the battery tank under a certain pressure. The flatness of the plate directly affects the pressure of assembly. In order to ensure the quality of the battery, the flatness of the plate must be strictly controlled.

[0003] The existing plate flatness measurement method is to take a certain number of plates (usually 50 plates in a stack), use a ruler to measure the height of several different points, and then use data statistics to calculate the height range to determine the plate flatness. This method of measuring and reading multiple times is time-consuming and laborious, and multiple measurements are prone to superposition of measurement errors, resulting in large deviations in the final measurement results.

[0004] The utility model with the authorization announcement number CN217585710U discloses a device for detecting the flatness of a battery plate, comprising: a workbench; a detection area, which is arranged on the workbench, and the detection area is used to horizontally stack a group of plates to be detected; a sorting mechanism, which is arranged on the workbench, and is used to sort a group of plates horizontally stacked in the detection area so that multiple plates are stacked neatly; a detection mechanism, which is arranged above the detection area, and is used to perform flatness detection on a group of plates to be detected. The detection mechanism includes a plurality of infrared ranging sensors arranged on the horizontal mounting plate, which correspond to different positions on the top surface of the plate. However, the infrared ranging sensor is used for detection in the prior art. On the one hand, the entire device is large in size and inconvenient to move. On the other hand, the surface of the plate is not a smooth surface, and the roughness of the surface of the plate is relatively large. When the infrared ranging sensor detects different positions, there may be large errors. Utility Model Content

DETAILED DESCRIPTION

[0027] like Figures 1 to 5 As shown, a measuring instrument for detecting the flatness of lead-acid battery plates includes a base 2. The top surface of the base 2 has a horizontal detection area for placing the plates 1 to be detected. During detection, several plates 1 are horizontally stacked in the detection area.

[0028] A column 3 is provided at one corner of the base 2, and the column 3 is vertically arranged on the base 2. A vertically distributed first scale 4 is provided on the column 3. In order to facilitate reading of the plate thickness value, the bottom 0 scale line of the first scale 4 on the column 3 is flush with the top surface of the detection area.

[0029] The column 3 is provided with a first cursor 5, which has a vertical connection hole for the column 3 to pass through, and the first cursor 5 and the column 3 are slidably matched up and down, and the first cursor 5 is provided with a first pressing plate 6 for pressing on the surface of the plate 1. The first cursor 5 is also provided with a vertical locking stud 14 for fixing the first cursor 5 to the column 3. When in use, when it is necessary to move the first cursor 5, the vertical locking stud 14 is loosened, and when the first cursor 5 is moved to the corresponding position, the vertical locking stud 14 is locked again, so that the first cursor 5 is fixed relative to the column 3.

[0030] The first cursor 5 is provided with a first horizontal pointer 12, and the height of the tip of the first horizontal pointer 12 is consistent with the height of the bottom surface of the first pressing plate 6. When the first pressing plate 6 is lightly pressed on the surface of the electrode 1, the height of the tip of the first horizontal pointer 12 represents the height of the bottom surface of the first pressing plate 6, that is, the thickness value of the electrode 1.

[0031] The first cursor 5 also has a horizontal connection hole for the transverse telescopic beam 7 to pass through, and the transverse telescopic beam 7 is horizontally slidably matched with the first cursor 5. The number of transverse telescopic beams 7 can be one, or two or more. In the embodiment shown in the figure, there are two transverse telescopic beams 7, and the two transverse telescopic beams 7 are arranged in parallel one above the other, which can ensure that the transverse telescopic beam 7 remains in a horizontal state. The first cursor 5 is also provided with a transverse locking stud 15 for fixing the transverse telescopic beam 7 to the first cursor 5. After adjusting the horizontal position of the transverse telescopic beam 7, the transverse locking stud 15 can be tightened to lock it.

[0032] A ruler 8 is provided at the far end of the transverse telescopic beam 7, and a second scale 9 is provided on the ruler 8 in a vertical distribution. The 0 scale line of the second scale 9 is consistent with the bottom height of the first pressing plate 6, and the second scale 9 has scales above and below the 0 scale line, with positive scales above, indicating that it is higher than the first pressing plate 6, and negative scales below, indicating that it is lower than the first pressing plate 6.

[0033] A second cursor 10 is provided at the scale 8, and the second cursor 10 and the scale 8 are slidably matched up and down, and a second pressing plate 11 for pressing on the surface of the electrode plate 1 is provided on the second cursor 10. A second horizontal pointer 13 is provided on the second cursor 10, and the height of the tip of the second horizontal pointer 13 is consistent with the height of the bottom surface of the second pressing plate 11. Therefore, when the second pressing plate 11 is lightly pressed on the surface of the electrode plate 1, the height of the tip of the second horizontal pointer 13 represents the height of the bottom surface of the second pressing plate 11, and the difference between the thickness of the electrode plate 1 at the second pressing plate 11 and the thickness of the electrode plate 1 at the first pressing plate 6 can be determined by reading the value of the second scale 9 indicated by the second horizontal pointer 13.

[0034] When the measuring instrument for detecting the flatness of the lead-acid battery plate of the utility model is used, a certain number of plates 1 (generally 50 plates in a stack) are first placed in the detection area of ​​the base 2, and the first cursor 5 on the column 3 is adjusted so that the first pressing plate 6 on the first cursor 5 is naturally lightly pressed on the first measuring point on the top surface of the plate 1, and then the vertical locking stud 14 is locked; the position of the transverse telescopic beam 7 is adjusted so that the second cursor 10 at the scale 8 at the far end of the transverse telescopic beam 7 is located at the second measuring point, so that the second pressing plate 11 is naturally lightly pressed on the surface of the plate 1, and the value read from the first scale 4 at this time is the total height of all the plates 1 at the first measuring point, and the value read from the second scale 9 is the height difference between the second measuring point and the first measuring point.
