Abstract
Description
Technical Field
[0001] This utility model relates to the field of storage battery manufacturing technology, specifically to a storage battery safety valve installation and inspection device. Background Technology
[0002] A lead-acid battery is a type of battery whose electrodes are primarily made of lead and its oxides, and whose electrolyte is a sulfuric acid solution. In the discharged state, the positive electrode is mainly composed of lead dioxide, and the negative electrode is mainly composed of lead; in the charged state, both the positive and negative electrodes are mainly composed of lead sulfate.
[0003] Multiple safety valves are required to be installed on lead-acid batteries. Patent document CN202695590U discloses a fully automatic safety valve installation and testing device for batteries. After the safety valve is installed, the battery passes under the sensor of the safety valve testing device. The sensor automatically detects whether the safety valve is correctly positioned. If the safety valve is installed correctly, the battery continues to the next process. If no safety valve is detected in the corresponding position, a horizontal push rod is activated, pushing the battery to the receiving rail. The level sensor on the receiving rail senses that the number of defective batteries on the rail has reached its limit and activates an alarm. By detecting the safety valves on the battery, the possibility of missing safety valves can be avoided, thus improving the product yield.
[0004] Patent document CN113777662B discloses a battery safety valve installation and inspection device. This device provides a detailed description of the inspection process: the battery is placed on a conveyor belt and transported from left to right to a positioning and clamping mechanism. At this point, the detection block is directly above the positioning and clamping mechanism. A servo motor is activated to drive the rotating arm to rotate 90° counterclockwise, causing the suction cup to rotate directly above the positioning and clamping mechanism. The suction head, using a vacuum pump, sucks up the safety valve from the material trough and rotates it above the battery. A longitudinal stepper motor drives the suction cup to descend, causing the safety valve to fall into the battery safety valve installation position. The vacuum pump of the suction head then stops suction, thus the safety valve is installed correctly. After installation, the servo motor drives the rotating arm back to its initial position. At this point, the detection block rotates to directly above the positioning and clamping mechanism. An infrared sensor at its bottom detects whether the safety valve is in place. Finally, the positioning and clamping mechanism releases the material. This installation and inspection method yields good results, with one servo motor enabling switching between the installation and inspection stations, resulting in high efficiency. The positioning and clamping mechanism uses a positioning cylinder to push the positioning plate forward, blocking the battery from further transport. The clamping cylinder then pushes the clamping plate backward to clamp the battery. The battery is guided and transported between the positioning and clamping plates by the front and rear guide plates. Initially, the infrared sensor can also detect the battery's installation position. This device requires a clamping mechanism for battery positioning, located on both sides of the battery. The positioning and clamping cylinders work in coordination to clamp and position the battery, making the clamping mechanism of this device relatively complex. Utility Model Content
[0005] The main purpose of this utility model is to provide a battery safety valve installation and inspection device that facilitates safety valve testing after battery positioning.
[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0007] A battery safety valve installation and inspection device includes a workbench with a conveyor belt mounted on it. A safety valve inspection assembly is positioned above the conveyor belt, and a battery positioning assembly is mounted on the safety valve inspection assembly. The safety valve inspection assembly includes an upper plate located above the conveyor belt and fixedly connected to the workbench. Multiple circular holes are evenly distributed along the conveyor belt's transport direction on the upper plate. Upper and lower covers corresponding to the circular holes are respectively positioned above and below the upper plate. The diameters of the upper and lower covers are equal, but larger than the diameters of the circular holes. A threaded sleeve is concentrically fixed to the upper end of the lower cover. A wing bolt passes through the upper cover and is threadedly connected to the threaded sleeve. An infrared probe is concentrically fixed to the lower end of the lower cover. Loosening the wing bolt allows adjustment of the positions of the upper and lower covers, threaded sleeve, wing bolt, and infrared probe.
[0008] Specifically, the upper plate and the worktable are fixedly connected by a support plate.
[0009] Specifically, the upper end of the conveyor belt is flush with the upper end of the worktable.
[0010] Specifically, the battery positioning assembly includes a first cylinder fixed on the upper plate. The first cylinder is vertically arranged, and a baffle is fixed on the telescopic end of the first cylinder. The baffle is located below the upper plate and can intercept and block the battery being transported by the conveyor belt. After the baffle intercepts and blocks the battery, multiple infrared probes are used to check the multiple safety valves of the battery respectively.
[0011] Specifically, the baffle includes a vertical part and a horizontal part, and the horizontal part of the baffle is fixedly connected to the telescopic end of the first cylinder.
[0012] Specifically, a groove is provided on the vertical part of the baffle. The length direction of the groove is perpendicular to the conveying direction of the conveyor belt. Two clamping plates are slidably arranged in the groove, and the clamping plates pass through the groove. Two second cylinders are fixed on the baffle. The two clamping plates are located between the two second cylinders. The telescopic end of the second cylinder is fixedly connected to the clamping plate on one side.
[0013] Specifically, the ends of the two clamps facing the direction of battery feeding are far apart from each other.
[0014] Specifically, the infrared probe, controller, power supply, and buzzer are electrically connected.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. The adjustable top cover, bottom cover, screw sleeve, and wing bolt design allow for easy adjustment of the infrared probe's position, making it adaptable to the safety valve detection requirements of batteries of different specifications. This solves the problem of a single device being incompatible with multiple battery models, improving the equipment's versatility and application range, and enabling quick switching of detection tasks without hardware replacement.
[0017] 2. This solution uses a simple combination of baffle, first cylinder, clamping plate, and second cylinder, eliminating the need for complex positioning and clamping cylinder coordination. This not only reduces the number of parts but also lowers manufacturing costs and maintenance difficulty, making the equipment more compact and easier to install.
[0018] 3. Integrating a conveyor belt, cylinder, and infrared sensor enables automatic battery transport, positioning, detection, and alarm functions. After the baffle intercepts the battery, the clamping plate automatically holds it for detection and then automatically releases it, all without manual intervention. The butterfly bolt design simplifies sensor adjustment, and the guide end design of the clamping plate facilitates battery insertion, improving operational efficiency and human-machine interface.
[0019] 4. Infrared sensors directly detect whether the safety valve is missing or improperly installed. An alarm is immediately triggered in case of an abnormality, alerting staff to handle defective products. This avoids battery safety hazards caused by missing or misaligned safety valves, ensuring that only qualified products proceed to the next process, thus improving product quality reliability and the factory pass rate.
[0020] 5. The detection components are seamlessly integrated with the conveyor belt, allowing the battery to be quickly positioned and detected during movement, reducing downtime. Furthermore, the positioning and detection processes are completed within a single workstation, improving production continuity, reducing equipment footprint, and making it suitable for large-scale production line environments.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Example 1: Refer to Figures 1-5 As shown, the battery safety valve installation and inspection device includes a workbench 1, a conveyor belt 2 installed on the workbench 1, the upper end of the conveyor belt 2 being flush with the upper end of the workbench 1, and a safety valve inspection component being installed above the conveyor belt 2.
[0029] The safety valve inspection assembly includes an upper plate 3, which is located above the conveyor belt 2 and is fixedly connected to the workbench 1 via a support plate 4. Multiple circular holes 5 are evenly distributed along the conveying direction of the conveyor belt 2 on the upper plate 3. An upper cover 6 and a lower cover 7, corresponding to the circular holes 5, are respectively provided above and below the upper plate 3. The diameters of the upper cover 6 and lower cover 7 are equal, but larger than the diameter of the circular holes 5. A threaded sleeve 9 is concentrically fixed to the upper end of the lower cover 7. A wing bolt 8 passes through the upper cover 6 and is threadedly connected to the threaded sleeve 9. An infrared probe 10 is concentrically fixed to the lower end of the lower cover 7. Loosening the wing bolt 8 allows adjustment of the positions of the upper cover 6, lower cover 7, threaded sleeve 9, wing bolt 8, and infrared probe 10.
[0030] The infrared sensor 10, controller, power supply, and buzzer are electrically connected.
[0031] After the battery moves on conveyor belt 2 to below the upper plate 3 and the multiple safety valves on the battery correspond to the multiple infrared sensors 10, conveyor belt 2 is turned off. The multiple infrared sensors 10 are then used to check the multiple safety valves of the battery. If a safety valve is missing, and the infrared sensor 10 cannot detect the safety valve below it, the infrared sensor 10 sends a signal to the controller, which then activates a buzzer to alert the operator that a defective product has been found. If the safety valve is not installed correctly, and the distance between the upper end of the safety valve and the infrared sensor 10 is outside the set range, the infrared sensor 10 sends a signal to the controller, which then activates a buzzer to alert the operator that a defective product has been found.
[0032] When inspecting the safety valves on batteries of different specifications, loosening the wing bolt 8 adjusts the positions of the upper cover 6, lower cover 7, screw sleeve 9, wing bolt 8, and infrared probe 10, allowing multiple infrared probes 10 to be used to inspect the safety valves on batteries of different specifications. After adjusting the position of the infrared probe 10, rotating the wing bolt 8 causes the upper cover 6 and lower cover 7 to press against the upper plate 3 between them, thus positioning the infrared probe 10.
[0033] Example 2: Based on Example 1, referring to... Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the valve inspection assembly is equipped with a battery positioning component.
[0034] The battery positioning assembly includes a first cylinder 11 fixed on the upper plate 3. The first cylinder 11 is vertically arranged, and a baffle 12 is fixed on the telescopic end of the first cylinder 11. The baffle 12 is located below the upper plate 3. The baffle 12 can intercept and block the battery being transported by the conveyor belt 2. After the baffle 12 intercepts and blocks the battery, multiple infrared probes 10 are used to check the multiple safety valves of the battery respectively.
[0035] The baffle 12 includes a vertical portion and a horizontal portion. The horizontal portion of the baffle 12 is fixedly connected to the telescopic end of the first cylinder 11. A groove 15 is provided on the vertical portion of the baffle 12. The length direction of the groove 15 is perpendicular to the conveying direction of the conveyor belt 2. Two clamping plates 13 are slidably disposed in the groove 15, and the clamping plates 13 pass through the groove 15. Two second cylinders 14 are fixed on the baffle 12, and the two clamping plates 13 are located between the two second cylinders 14. The telescopic end of the second cylinder 14 is fixedly connected to the clamping plate 13 on one side of it. The ends of the two clamping plates 13 facing the direction of battery feeding are far apart from each other.
[0036] In this embodiment, in order to facilitate the positioning of the battery, a baffle 12 that can move up and down is provided to intercept, block and release the battery.
[0037] During the transport of the battery on conveyor belt 2, baffle 12 is at its lower stop point. After blocking the battery, baffle 12 positions the battery in the transport direction of conveyor belt 2. At this time, the battery is located between two clamping plates 13. Two second cylinders 14 are activated, and the two clamping plates 13 clamp the battery. At this time, multiple infrared sensors 10 correspond to multiple safety valves on the battery. Then, the infrared sensors 10 can check the safety valves.
[0038] After the safety valve on the battery is inspected and found to be installed correctly, the second cylinder 14 causes the clamping plate 13 to return to its original position, and the first cylinder 11 drives the baffle 12 upward. After the baffle 12 moves to the upper dead point, it loses its blocking effect on the battery, and the battery is released and transferred to the next processing station.
[0039] Since the ends of the two clamping plates 13 facing the direction of battery feeding are far apart, when the baffle 12 blocks the battery, it is easy for the battery to move between the two clamping plates 13, which facilitates the subsequent clamping and positioning of the battery by the two clamping plates 13.
[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
