Abstract
Description
Technical Field
[0001] This utility model belongs to the field of testing tooling technology, and specifically relates to a device for detecting the dent depth of a square aluminum-cased battery. Background Technology
[0002] In the production of new energy power battery packs, the depth of the casing indentation is a key indicator affecting the subsequent module stacking and welding. During the cell manufacturing process, only the overall thickness is measured, which may overlook regional indentations. Traditional inspection methods for the PACK section have the following problems: manual visual inspection is inefficient and easily affected by subjective judgment; contact measurement is prone to secondary damage, while non-contact laser inspection is expensive. Utility Model Content
[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a square aluminum-cased battery dent depth detection device to solve the problems mentioned in the background art.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A square aluminum-cased battery indentation depth detection device includes a base and a support plate. The support plate is mounted on the base via a lifting support seat. A support seat for supporting the battery cell is installed below the support plate. An insertion rod is inserted into the support plate. A display slider is installed at the top of the insertion rod. The display slider protrudes from the top of the support plate. The display slider remains stationary or floats as the insertion rod is inserted into the groove of the battery cell.
[0006] Place the battery cell on the support base and insert the probes into the recesses of the battery cells to be tested one by one. If the recess depth is qualified, the display slider will stay still. If the recess depth is too shallow, the display slider will float up. By observing or testing the state of the display slider, you can quickly determine whether each recess on the battery cell is qualified. The structure is simple and the effect is intuitive.
[0007] Preferably, the diameter of the display slider is larger than the inner diameter of the socket on the support plate.
[0008] When not in use, the insertion rod hangs down naturally, indicating that the slider is positioned on the support plate.
[0009] Preferably, the outer wall of the display slider is coated with a fluorescent coating.
[0010] The fluorescent coating makes it easy to observe the status of the slider.
[0011] Preferably, a laser level is mounted on the support plate, with the laser level's emitting end facing the display slider.
[0012] The laser level emits a horizontal beam of light, making it easy to display the status of the slider.
[0013] Preferably, the lifting support base includes multiple sets of sliding rods, and the sliding rods are fixed to the support plate by a fixing ring.
[0014] The height of the support plate is adjusted along the slide bar, and the height of the bottom of the insertion rod follows the rise and fall of the support plate. Coarse adjustment is made to accommodate battery cells of different heights, thicknesses, and recess depths. When the height of the support plate is appropriate, tighten the fixing ring to fix the support plate.
[0015] Preferably, at least two sets of slide rods are fitted with springs, and the springs abut against the retaining rings.
[0016] When adjusting the height of the support plate, the spring acts as a buffer to prevent the support plate from falling directly and causing damage.
[0017] Preferably, the support includes a first cylinder and a gripper, the gripper being mounted on the output shaft of the first cylinder, the first cylinder extending or retracting toward the support plate.
[0018] The grippers are used to support the battery cells. The first cylinder drives the grippers to rise and fall, which can not only finely adjust to battery cells with different heights, thicknesses and recess depths, but also fit the recesses onto the outside of the plug, reducing manual operation.
[0019] Preferably, a second cylinder is also installed on the support plate. The output end of the second cylinder passes through the support plate and faces downwards, and a positioning pin is installed thereon. The height difference between the bottom end of the positioning pin and the bottom end of the insertion rod in the vertical direction is equal to the specified depth of the cell recess.
[0020] The second cylinder adjusts the height of the bottom end of the positioning pin, adjusting the height difference between the bottom end of the positioning pin and the bottom end of the insertion rod in the vertical direction to adapt to the requirements of different cell recess depths.
[0021] Preferably, the base is provided with a testing station and an installation station, the support plate is located on the testing station, the base is equipped with a slide rail that runs through the testing station and the installation station, a slide table is slidably installed on the slide rail, and a support seat is installed on the slide table.
[0022] The dual-station design facilitates the installation and testing of battery cells, improving work efficiency.
[0023] This utility model proposes a square aluminum-cased battery dent depth detection device. The dual-station design facilitates the installation of the detection box and improves work efficiency. The device is adaptable to different specifications of battery cells through a lifting support base and a liftable support base. By combining a laser level and visual inspection, the detection cost is reduced and the detection accuracy is improved.
[0024] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

A slide table 3 is slidably installed on the slide rail 2. A support seat 4 for supporting the battery cell is mounted on the slide table 3. An insertion rod 8 is inserted into the support plate 6. A display slider 9 is installed at the top of the insertion rod 8. The diameter of the display slider 9 is larger than the inner diameter of the insertion hole on the support plate 6. The display slider 9 protrudes from the top of the support plate 6. The display slider 9 remains stationary or floats as the insertion rod 8 is inserted into the groove of the battery cell.
[0034] A second cylinder 72 is also installed on the support plate 6. The output end of the second cylinder 72 passes through the support plate 6 and faces downwards, and a positioning pin 7 is installed thereon. The height difference between the bottom end of the positioning pin 7 and the bottom end of the insertion rod 8 in the vertical direction is equal to the specified depth of the cell recess.
[0035] The support 4 includes a first cylinder 41 and a gripper 42. The gripper 42 is mounted on the output shaft of the first cylinder 41, and the first cylinder 41 extends or retracts toward the support plate 6.
[0036] Preferably, a laser level 10 is mounted on the support plate 6, with the emitting end of the laser level 10 facing the display slider 9.
[0037] Preferably, the outer wall of the display slider 9 is coated with a fluorescent coating.
[0038] The lifting support base 5 includes multiple sets of slide rods 51, as shown in the figure. Four sets of slide rods 41 are respectively installed at the four corners of the support plate 6, and the slide rods 51 and the support plate 6 are fixed relative to each other by fixing rings 53. Preferably, the fixing rings 53 and the slide rods 51 are connected by threads.
[0039] Preferably, at least two sets of slide rods 51 are fitted with springs 52, the two sets of slide rods 51 are located diagonally opposite each other on the support plate 6, and the springs 52 abut against the fixing rings 53.
[0040] Spring 52 is a compression spring and always has an upward thrust.
[0041] Preferably, a stop block 21 is installed on the side of the slide rail away from the mounting components. When the slide table 3 abuts against the stop block 21, the battery cell is located at the detection position. The stop block 21 has the function of positioning the slide table 3.
[0042] Preferably, a handle 31 is installed on the side of the slide table 3 away from the detection component to facilitate switching the slide table 3 between the detection station and the installation station.
[0043] Working principle: Visually estimate the height of the battery cell and roughly adjust the height of the support plate 6; according to the depth requirements of the battery cell groove, adjust the vertical height difference between the bottom end of the positioning pin 7 and the bottom end of the insertion rod 8, i.e., the insertion rod 8 remains stationary while the second cylinder 71 adjusts the height of the positioning pin 7; drag the slide table 3 to the installation position, then place the battery cell to be tested on the gripper 42, push the handle 31 to push the slide table 3 below the support plate 6 until the slide table 3 abuts against the stop block 21, and the first cylinder 41 pushes the battery cell upward so that the insertion rod 8 is inserted into the groove until the battery cell contacts the bottom end of the positioning pin 7; turn on the laser level 10 and observe whether the display slider 9 floats up. If it floats up, the groove depth is unqualified; otherwise, it is qualified.
