Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, and more specifically, to a lead-carbon battery airtightness monitoring device. Background Technology

[0002] Lead-carbon batteries are an advanced type of lead-acid battery. They incorporate activated carbon material into the negative electrode of traditional lead-acid batteries, which greatly improves the battery's cycle life, charge acceptance, and performance under partial state of charge. During the production process, lead-carbon batteries require airtightness monitoring devices for airtightness monitoring.

[0003] Existing airtightness monitoring devices typically use a roller conveyor to transport batteries to a monitoring platform, where they are then clamped by a clamping mechanism before monitoring. However, during clamping, the clamping mechanism cannot accurately position the batteries, leading to easy battery displacement and poor installation. Furthermore, loading and unloading can only proceed after battery monitoring is complete, further compromising usability. Therefore, we propose an airtightness monitoring device for lead-carbon batteries. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example

[0021] Reference Figures 1-4 This utility model provides a technical solution: a lead-carbon battery airtightness monitoring device, including a base 1, several support legs 15 installed on the bottom edge of the base 1, and a control cabinet 22 installed on the bottom edge of the base 1. The control cabinet 22 contains a controller, which can be a Siemens S7-1200 or other compatible controller. like Figure 1 and Figure 2 As shown, a support frame 9 is installed on one side of the top of the base 1. The support frame 9 is connected to a sealing plug 16 through an adjustment mechanism. The adjustment mechanism includes a mounting base 5 located below the support frame 9. The top of the mounting base 5 is connected to the top of the support frame 9 through a first electric push rod 7. The first electric push rod 7 is connected to a controller through a wire. The bottom of the mounting base 5 is connected to the sealing plug 16 through a floating joint. The sealing plug 16 is connected to a gas source through a pipe. In actual use, the mounting base 5 can be moved up and down by the first electric push rod 7, thereby controlling the height of the sealing plug 16. The sealing plug 16 can block the liquid injection hole or vent hole on the battery. Then, the gas in the gas source is transported into the battery through the pipe, and the gas pressure inside the battery is monitored. This allows for monitoring of the airtightness of the battery.

[0022] It should be noted that, as Figure 1 and Figure 2As shown, connecting blocks 8 extend from both sides of the mounting base 5. A second limiting rod 6 is vertically installed on the top of each connecting block 8. The top of the second limiting rod 6 slides through the top of the support frame 9. The mounting base 5 can be limited by the second limiting rod 6, so that the mounting base 5 remains stable.

[0023] like Figure 3 As shown, a rotating shaft 19 is rotatably connected to the top of the base 1, and a drive motor 17 is connected to the bottom of the rotating shaft 19. The drive motor 17 is fixed to the bottom of the base 1. A rotating platform 3 is installed on the top of the rotating shaft 19, and several worktables 12 are installed on the top edge of the rotating platform 3. The drive motor 17 is connected to the controller through wires. When in use, the operator places the battery on the worktable 12, and the drive motor 17 drives the rotating shaft 19 to rotate. The rotating shaft 19 drives the rotating platform 3 to rotate, thereby moving the worktable 12 containing the battery to below the sealing plug 16 for monitoring.

[0024] It should be noted that an infrared sensor 26 is installed at the bottom of the support frame 9. The infrared sensor 26 is connected to the controller in the control cabinet 22 via a wire. The infrared sensor 26 is model VL53L1X. The position of the workbench 12 can be monitored by the infrared sensor 26. When the workbench 12 moves to the preset position under the support frame 9, the infrared sensor 26 will transmit the monitored signal to the controller. After receiving the signal, the controller will control the drive motor 17 to stop working and fix the workbench 12 under the support frame 9, so as to facilitate the monitoring of the battery on the workbench 12.

[0025] like Figure 1 and Figure 2 As shown, the top of the rotary table 3 is equipped with an isolation plate 4. Each worktable 12 is located between two adjacent isolation plates 4. When the battery is placed on the worktable 12, one side of the battery can be pressed against the side of the isolation plate 4 to initially position the battery, so that the battery will not shift its position during monitoring.

[0026] like Figure 1 and Figure 2 As shown, an annular support seat 14 is also installed on the top of the base 1. The top of the annular support seat 14 is connected to the edge of the rotary table 3 through a bearing. The annular support seat 14 can support the edge of the rotary table 3, so that the rotary table 3 remains stable.

[0027] like Figure 1 and Figure 4As shown, the top two sides of the workbench 12 are symmetrically provided with through slots 13, the bottom of the through slots 13 penetrates the rotary table 3, and each through slot 13 is provided with a strip-shaped moving block 10. Both ends of the strip-shaped moving block 10 extend to the outside of the through slot 13, and each pair of strip-shaped moving blocks 10 has a clamping plate 11 installed on the adjacent top surfaces. The battery placed on the workbench 12 can be clamped and fixed by the two clamping plates 11, thus preventing the battery from moving during the monitoring process.

[0028] like Figure 3 and Figure 4 As shown, several second electric push rods 21 are installed at the bottom of the rotary table 3. Each second electric push rod 21 is connected to a conductive mechanism via a wire. The conductive mechanism includes a conductive slip ring 18 coaxially fixed on the side of the rotating shaft 19. The fixed ring of the conductive slip ring 18 is fixed on the top of the base 1 and is connected to the controller in the control cabinet 22 via a wire. The moving ring of the conductive slip ring 18 is connected to the side of the rotating shaft 19 and is connected to the second electric push rod 21 via a wire. When the second electric push rod 21 rotates with the rotary table 3, the controller can supply power to the second electric push rod 21 normally through the conductive slip ring 18.

[0029] like Figure 3 and Figure 4 As shown, a fixed base 20 is installed at the bottom of the second electric push rod 21. Grooves 24 are provided on both sides of the fixed base 20. A connecting rod 23 is rotatably connected in each groove 24. An opening slot 25 is provided at the bottom of each strip-shaped moving block 10. The other end of the connecting rod 23 extends into the corresponding opening slot 25 and is rotatably connected to the opening slot 25. The extension and retraction of the second electric push rod 21 can drive the connecting rod 23 to rotate. This can control the relative movement of two adjacent strip-shaped moving blocks 10, thereby controlling the relative movement of two adjacent clamping plates 11 to clamp and fix the battery.

[0030] like Figure 1 and Figure 4 As shown, each through slot 13 is equipped with a first limiting rod 2, which slides through the corresponding strip-shaped moving block 10. The first limiting rod 2 can guide and limit the strip-shaped moving block 10, so that the strip-shaped moving block 10 can remain stable.

[0031] Specifically, when using this utility model, the operator places the battery on the corresponding workbench 12, so that one side of the battery abuts against the side of the isolation plate 4. Then, the operator controls the second electric push rod 21 to extend through the controller. The second electric push rod 21 drives the fixed seat 20 to move down. During the downward movement, the fixed seat 20 drives the connecting rod 23 to rotate. The connecting rod 23 drives the strip moving block 10 to move horizontally along the through groove 13. The strip moving block 10 drives the clamping plate 11 to move, clamping and fixing the battery. At the same time, the battery is positioned to prevent the battery position from shifting. Then, the controller controls the drive motor 17 to work, which drives the rotating shaft 19 to rotate. The rotating shaft 19 drives the rotating table 3 to rotate, moving the workbench 12 containing the battery below the sealing plug 16. At this time, the workbench 12 without the battery is rotated to the front of the worker, who can place the battery on the empty workbench 12. While placing the battery, the controller controls the first electric push rod 7 to extend, pushing the mounting base 5 down. The mounting base 5 drives the sealing plug 16 down, so that the sealing plug 16 blocks the liquid injection hole on the battery. Then, the gas in the external air source is transported into the battery through the pipe and the air passage in the sealing plug 16 to monitor the airtightness of the battery. This allows for loading and unloading during the monitoring process, improving the usage effect.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
