Description

Technical Field

[0001] The utility model relates to the technical field of battery core detection, in particular to a battery core diameter detection tool. Background Art

[0002] At present, in the production process of cylindrical lithium-ion batteries, the diameter of the battery cell is a very important control characteristic. It has a great impact on the subsequent production processes of the battery cell, such as shelling and liquid injection, and has an important impact on the electrical performance and safety performance of the finished battery cell.

[0003] When testing battery cells, measurements are generally performed using a vernier caliper or a through gauge. Since the battery cell is not strictly cylindrical and has raised portions on the negative and positive tabs, such instruments require data collection from multiple locations, resulting in low measurement efficiency. Furthermore, when measuring with a through gauge, the battery cell needs to be repeatedly compared with different through gauges, resulting in low measurement efficiency. Utility Model Content

[0004] The problem solved by the present invention is to provide a tool for detecting the diameter of a battery cell, which solves the technical problem that when performing battery cell detection, measurement is generally performed using a vernier caliper or a through gauge. Since the battery cell is not strictly cylindrical in shape and has raised parts on the negative ear side and the positive ear side, data needs to be collected from multiple locations when such instruments are used for measurement, resulting in low measurement efficiency. In addition, when measuring with a through gauge, the battery cell needs to be repeatedly compared with different through gauges, resulting in low measurement efficiency.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A battery cell diameter detection tool comprises a base, a support ring, a ring seat, a guide rail and a T-block. The base is provided with a support ring, the top of the support ring is provided with a ring seat, several groups of guide rails are provided at equal angles on the ring seat, each group of guide rails is slidably provided with a T-block, the base is provided with a vertical frame, a lifting arm is slidably provided in the vertical frame, a measuring cover is provided at the bottom end of the lifting arm, several diameter intervals are provided on the measuring cover, and the inner diameter of the measuring cover gradually decreases from bottom to top.

[0007] Preferably, a motor is installed on the lifting arm, and a threaded rod is installed on the output end of the motor located in the vertical frame, and the threaded rod is threadedly connected to the lifting arm.

[0008] Preferably, a gear ring is rotatably mounted on the outer side of the support ring, rotating teeth are mounted on the base, and the rotating teeth are engaged with the gear ring, and the gear ring is connected to the output end of the regulating motor at the bottom of the base.

[0009] Preferably, a plurality of linear grooves are provided on the ring seat at equal angles, and a plurality of arc grooves are provided on the gear ring at equal angles.

[0010] Preferably, a guide rod is installed on the bottom side of the T-block, and the guide rod passes through the linear groove and the arc groove.

[0011] Preferably, the measuring cover is made of transparent plastic material.

[0012] The beneficial effects of the utility model are as follows: through the rotation of the gear ring, the arc groove acts on the guide rod, which in turn drives the guide rod to move along the linear groove, drives the T-shaped block to move on the guide rail, and multiple guide rails move synchronously to clamp different specifications of battery cells at the center position of the support ring, thereby achieving clamping, fixation and center positioning of the battery cells;

[0013] The battery cell is measured by a moving measuring cover, and the top of the battery cell blocks the descending measuring cover. At this time, the diameter range where the top of the battery cell is located is the diameter of the battery cell, realizing rapid detection of the battery cell diameter.

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] Specific examples are given below.

[0020] See also Figure 1 and Figure 2A battery core diameter detection tooling includes a base 1, a support ring 2, a ring seat 3, a guide rail 4 and a T-block 5. The base 1 is equipped with a support ring 2, a ring seat 3 is installed on the top of the support ring 2, and a plurality of guide rails 4 are installed at equal angles on the ring seat 3. Each guide rail 4 is slidably installed with a T-block 5. A gear ring 12 is rotatably installed on the outer side of the support ring 2. A rotating gear 13 is installed on the base 1, and the rotating gear 13 is engaged with the gear ring 12. The gear ring 12 is connected to the output end of the adjustment motor at the bottom of the base 1. The ring seat 3 is opened at equal angles. There are several straight grooves 14, and several arc grooves 15 are opened at equal angles on the gear ring 12. A guide rod 16 is installed on the bottom side of the T-block 5, and the guide rod 16 passes through the straight groove 14 and the arc groove 15. By adjusting the operation of the motor, the rotating gear 13 is driven to rotate, and the meshing gear ring 12 is driven to rotate. When the gear ring 12 rotates, the arc groove 15 of the gear ring 12 acts on the guide rod 16, driving the guide rod 16 to move along the straight groove 14 of the ring seat 3, thereby driving the T-block 5 to move on the guide rail 4, and then clamping and positioning the battery cell;

[0021] A vertical frame 6 is installed on the base 1, and a lifting arm 9 is slidably installed in the vertical frame 6. A measuring cover 10 is installed at the bottom of the lifting arm 9. A motor 8 is installed on the lifting arm 9. The output end of the motor 8 is located in the vertical frame 6 and a threaded rod 7 is installed. The threaded rod 7 is threadedly connected to the lifting arm 9. The motor 8 drives the threaded rod 7 to rotate, and then drives the threaded lifting arm 9 to rise and fall along the vertical frame 6 to adjust the height of the measuring cover 10. Several diameter intervals 11 are provided on the measuring cover 10, and the inner diameter of the measuring cover 10 gradually decreases from bottom to top. The measuring cover 10 is made of transparent plastic, which is convenient for observing the position of the battery cell.

[0022] The battery cell is placed vertically in the support ring 2 of the base 1. At this time, the motor is adjusted to drive the rotating gear 13 to rotate, and the meshing gear ring 12 is driven to rotate. When the gear ring 12 rotates, the arc groove 15 of the gear ring 12 acts on the guide rod 16, driving the guide rod 16 to move along the linear groove 14 of the ring seat 3, thereby driving the T-block 5 to move on the guide rail 4. Multiple guide rails 4 move synchronously to clamp the battery cell in the center position of the support ring 2. The motor 8 drives the threaded rod 7 to rotate, and then drives the threaded lifting arm 9 to rise and fall along the vertical frame 6, and adjust the height of the measuring cover 10 until the top of the battery cell blocks the descending measuring cover 10. At this time, the diameter interval 11 where the top of the battery cell is located is the diameter of the battery cell. The detection is completed, the measuring cover 10 moves up, and the battery cell is removed from the tooling.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
