Description

Technical Field

[0001] The utility model relates to the technical field of battery testing, in particular to a multi-station battery testing machine. Background Technique

[0002] Before the battery leaves the factory, to ensure that its quality meets the standards, a series of performance tests and fault detections are usually required. The battery testing machine is a professional device that performs this task. This device can accurately measure key parameters such as the capacity and internal resistance of the battery, and deeply analyze its charge and discharge characteristics. In addition, the battery testing machine also has the ability to scientifically evaluate the service life and safety of the battery, so as to ensure that the battery products can meet various performance indicators and safety standards in actual applications.

[0003] Most of the existing battery testing machines can only perform fixed tests on batteries of the same model. When fixing different batteries, it is often necessary to replace the operator manually to replace the fixing device, which affects the testing efficiency. And most of the devices are insufficiently prepared for safety emergency handling. Once a battery catches fire suddenly during the testing process, relying on manual use of fire extinguishers to extinguish the fire not only has a lagging response and low efficiency, unable to quickly control the fire, but also seriously threatens the personal safety of on-site operators and the integrity of the testing equipment.

[0004] Therefore, the utility model provides a multi-station battery testing machine to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a multi-station battery testing machine is proposed. In the battery testing machine, by placing the battery on the sliding plate, the gravity of the battery itself will exert pressure on the fixed block and the first compression spring, causing them to compress, so as to adapt to and fix batteries of different sizes. During the battery testing process, if a fire occurs, the high temperature generated will cause the thermal-sensitive glass to break, thereby releasing the energy stored in the spring, pulling the limit ball upward, so that the dry powder fire extinguishing agent inside the device is sprayed onto the fire source through the fire extinguishing pipe to quickly perform fire extinguishing operations to control the fire.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A multi-station battery testing machine includes a device main body. A base is fixedly arranged at the lower end of the device main body. An installation plate is slidably arranged on the upper end of the base. Two sliding plates are slidably arranged inside the installation plate. A plurality of first compression springs are fixedly arranged inside both of the two sliding plates. Fixed blocks are fixedly arranged on one side of each pair of the plurality of first compression springs.

[0008] A cylinder is fixedly arranged at the upper end inside the device main body. A connecting plate is fixedly arranged at the output end of the cylinder. Two fire extinguishing pipes are arranged inside the device main body. The input ends of the two fire extinguishing pipes are fixedly arranged on both sides inside the connecting plate. Two springs are fixedly arranged inside the connecting plate. Limiting balls are fixedly arranged at the lower ends of the two springs. Thermosensitive glasses are fixedly arranged at the lower ends of the two limiting balls. The lower ends of the two thermosensitive glasses are fixedly arranged at the lower end inside the connecting plate.

[0009] Through the above technical solution, when the battery is placed inside the sliding plate during the test, the pressure of the battery sinking squeezes the first compression spring and the fixed block, so that the device adapts to the differences in the sizes of various batteries, ensuring the firm and stable positioning of the battery during the test, demonstrating flexibility. When an emergency situation of abnormal heating or even fire of the battery unfortunately occurs during the test, the thermosensitive glass inside the connecting plate breaks, causing the energy of the spring to be instantly released, pushing the limiting ball to move upward inside the connecting plate, and then enabling the dry powder to directly hit the fire source through the fire extinguishing pipe, quickly extinguishing the fire, thus building a solid safety defense line for the test environment.

[0010] Further, a plurality of upper elastic probes are fixedly arranged at the lower end of the connecting plate, and a plurality of lower elastic probes are fixedly arranged at the upper end of the base.

[0011] Through the above technical solution, during detection, the upper elastic probes on the connecting plate and the lower elastic probes on the base jointly form battery contact points to realize the test operation on the battery.

[0012] Further, a rack is fixedly arranged at the rear end of the mounting plate. A motor is fixedly arranged at the rear end inside the device main body. A gear is fixedly arranged at the output end of the motor. The outside of the gear is meshed and connected to the rear end of the rack.

[0013] Through the above technical solution, when the motor starts, the meshing of the gear and the rack drives the mounting plate to slide longitudinally, improving the efficiency of battery testing.

[0014] Further, two connecting blocks are fixedly arranged on both sides of the two sliding plates. Rubber blocks are fixedly arranged at the lower ends of the eight connecting blocks. Second compression springs are fixedly arranged at the lower ends of the eight connecting blocks.

[0015] Through the above technical solution, when the sliding plate moves downward, it will drive the connecting blocks on both sides to move downward, simultaneously drive the rubber blocks to move downward, and make the second compression springs contract, providing a buffering and shock-absorbing effect for the sliding plate.

[0016] Further, a plurality of fixing holes are opened at the lower end inside the plurality of sliding plates. The lower ends of the eight second compression springs are fixedly arranged at the lower end inside the mounting plate. The outside of the eight rubber blocks is slidably arranged inside the mounting plate.

[0017] Through the above technical solution, when the second compression spring contracts and drives the rubber block to move, the rubber block will slide inside the mounting plate, thus ensuring the stable positioning of the sliding plate.

[0018] Further, four guide posts are slidably arranged inside the connecting plate. The lower ends of the four guide posts are fixedly arranged at the upper end of the base, and the upper ends of the four guide posts are fixedly arranged inside the upper part of the device main body;

[0019] Through the above technical solution, when the connecting plate slides, it will slide outside the guide posts inside it, and the guide posts provide stability for the movement of the connecting plate.

[0020] Further, a display screen is fixedly arranged at the front end of the device main body, and a protection door is hingedly arranged at the front end of the device main body;

[0021] Through the above technical solution, the display screen displays the data of the battery test in real time. The protection door is closed when not in use, protecting the internal structure from external interference and facilitating later maintenance.

[0022] The utility model has the following beneficial effects:

[0023] 1. For a multi-station battery tester proposed by the utility model, when an accidental fire occurs during the battery test, the temperature inside the device main body surges, which in turn causes the thermal-sensitive glass inside the connecting plate to break. The spring releases the stored energy due to the breakage of the thermal-sensitive glass, enabling the limit ball to move inside the connecting plate. As a result, the dry powder fire extinguishing agent stored in the device main body is quickly and accurately sprayed towards the fire source through the fire extinguishing pipe, achieving rapid fire extinguishing, effectively controlling the spread of the fire, building a solid safety defense line for the test environment, reducing the fire risk in battery testing, and protecting the safety of operators and equipment.

[0024] 2. For a multi-station battery tester proposed by the utility model, during the battery installation stage, by firmly embedding the battery into the fixing block inside the sliding plate, its own weight will be converted into the pressing force on the fixing block. Subsequently, the pressure is sequentially transmitted to the first compression spring inside the sliding plate, causing the first compression spring to generate an appropriate amount of deformation. This not only demonstrates the flexible adaptability to different types of batteries but also realizes the stable and reliable fixation of the battery during the test process, enhancing the flexibility and stability of the test operation and improving the efficiency of battery testing.

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0035] Refer to Figure 1-7 One embodiment provided by the present utility model:

[0036] A multi-station battery testing machine, comprising a device main body 1, a base 4 is fixedly arranged at the lower end of the device main body 1, a mounting plate 5 is slidably arranged at the upper end of the base 4, two sliding plates 13 are slidably arranged inside the mounting plate 5, a plurality of first compression springs 12 are fixedly arranged inside both of the two sliding plates 13, fixing blocks 19 are fixedly arranged on one side where a plurality of the first compression springs 12 face each other in pairs, a plurality of upper elastic probes 21 are fixedly arranged at the lower end of a connecting plate 9, a plurality of lower elastic probes 20 are fixedly arranged at the upper end of the base 4, a display screen 2 is fixedly arranged at the front end of the device main body 1, a protective door 3 is hingedly arranged at the front end of the device main body 1, a cylinder 8 is fixedly arranged inside the device main body 1 near the upper end, a connecting plate 9 is fixedly arranged at the output end of the cylinder 8, two fire extinguishing pipes 7 are arranged inside the device main body 1, the input ends of both of the two fire extinguishing pipes 7 are fixedly arranged on both sides inside the connecting plate 9, two springs 22 are fixedly arranged inside the connecting plate 9, limit balls 23 are fixedly arranged at the lower ends of both of the two springs 22, heat-sensitive glasses 24 are fixedly arranged at the lower ends of both of the two limit balls 23, and the lower ends of both of the two heat-sensitive glasses 24 are fixedly arranged at the lower part inside the connecting plate 9;

[0037] When fixing the battery, it is placed in the fixing block 19 inside the sliding plate 13 so that the battery's own weight squeezes the fixing block 19, and then the fixing block 19 squeezes the first compression spring 12 connected inside the sliding plate 13, so that the battery appropriately squeezes the fixing block 19 and the first compression spring 12, thereby flexibly adapting to and firmly locking batteries of different sizes, thereby improving the flexibility and stability of the test, and then starting the cylinder 8 to drive the connecting plate 9 to move. The connecting plate 9 is connected to the base 4 and the device body 1 through four guide columns 6 to achieve up and down sliding, ensuring that the connecting plate 9 moves up and down stably under the drive of the cylinder 8, thereby improving the test accuracy, and the upper elastic probe 21 at the lower end of the connecting plate 9 will detect the battery fixed on the sliding plate 13, and the guide column 6 plays a guiding and supporting role to ensure that the connecting plate 9 will not deflect or shake when sliding up and down. When an abnormality is encountered during the test process, causing a fire crisis, the thermal glass 24 inside the connecting plate 9 will sense High temperature and rupture, the thermosensitive glass 24 contains special thermosensitive materials, which will change significantly with the change of temperature. When the temperature rises, the material inside it expands, and then the glass outside it breaks, and then the connection between the thermosensitive glass 24 and the limiting ball 23 is released, so that the opened spring 22 is started, so that it rebounds and drives the limiting ball 23 connected to it to move upward along the inside of the connecting plate 9, so that the dry powder fire extinguishing agent inside the device body 1 is quickly and accurately delivered to the core of the fire source through the fire extinguishing pipe 7, and efficient fire extinguishing operations are performed, effectively curbing the spread of fire, ensuring the safety of the test environment, and reducing possible fire accidents during battery testing. The display screen 2 is used to display battery test data and results, provide intuitive information display, and facilitate operators to view and analyze test results. The protective door 3 is used to protect the safety of the battery and operators during the test, prevent accidental touch and misoperation, improve safety, and reduce the occurrence of accidents.

[0038] A rack 11 is fixedly provided at the rear end of the mounting plate 5, and a motor 15 is fixedly provided inside the device body 1 near the rear end. A gear 14 is fixedly provided at the output end of the motor 15, and the gear 14 is externally meshed and connected to the rear end of the rack 11. When the mounting plate 5 is made to slide on the base 4, the gear 14 is driven to rotate by the motor 15 inside it, and the gear 14 meshes with the rack 11 at the rear end of the mounting plate 5, thereby driving the mounting plate 5 connected to the gear 14 to slide on the base 4, thereby realizing the movement of the mounting plate 5, making the operation safer, reducing the operator's contact with the lower elastic probe 20 and the upper elastic probe 21, and improving the safety of the operation. By controlling the rotation of the motor 15, the position of the mounting plate 5 can be accurately adjusted to improve the accuracy of the test.

[0039] Two connecting blocks 18 are fixedly arranged on both sides of each of the two sliding plates 13. Rubber blocks 16 are fixedly arranged at the lower ends of the eight connecting blocks 18, and second compression springs 17 are fixedly arranged at the lower ends of the eight connecting blocks 18. A plurality of fixing holes 10 are formed in the inner parts of the plurality of sliding plates 13 near the lower ends. The lower ends of the eight second compression springs 17 are fixedly arranged in the inner part of the mounting plate 5 near the lower end. The outer parts of the eight rubber blocks 16 are slidably arranged in the inner part of the mounting plate 5. Four guide posts 6 are slidably arranged in the connecting plate 9. The lower ends of the four guide posts 6 are fixedly arranged at the upper end of the base 4, and the upper ends of the four guide posts 6 are fixedly arranged at the upper part near the inner part of the device main body 1. Four guide posts 6 are slidably arranged in the connecting plate 9. The lower ends of the four guide posts 6 are fixedly arranged at the upper end of the base 4, and the upper ends of the four guide posts 6 are fixedly arranged at the upper part near the inner part of the device main body 1;

[0040] When the sliding plate 13 inside the mounting plate 5 moves to the test position, the air cylinder 8 drives the connecting plate 9 to move, so that the upper elastic probe 21 at the lower end of the connecting plate 9 tests the battery fixed inside the sliding plate 13. When the upper elastic probe 21 tests the battery, the sliding plate 13 will slide inside the mounting plate 5, so that the upper elastic probe 21 at the upper end of the base 4 tests the battery inside it through the fixing hole 10 formed at the lower end of the sliding plate 13, and then drives the connecting block 18 and the rubber block 16 outside it to slide downward inside the mounting plate 5. When the connecting block 18 slides, it will squeeze the second compression spring 17 connected to it. The second compression spring 17 has a rebounding effect. When the rubber block 16 moves to the limiting hole at the upper end of the base 4, the stability between the connection and the base 4 is improved, the shaking is prevented, the test stability is improved, and the rubber block 16 can play a buffering role, slow down the impact driven by the upper elastic probe 21, and prevent damage to the tested battery.

[0041] Working principle: During the battery fixing process, by placing the battery in the fixing block 19 within the sliding plate 13, the weight of the battery itself is used to exert pressure on the fixing block 19, thereby compressing the first compression spring 12 connected inside the sliding plate 13, causing the battery to moderately squeeze the fixing block 19 and the first compression spring 12, and then enabling the fixing block 19 and the first compression spring 12 to flexibly adapt to and firmly lock batteries of various sizes, improving the flexibility and stability of the test. Then, the air cylinder 8 is started to drive the connecting plate 9 to move, so that the upper elastic probe 21 under the connecting plate 9 detects the battery fixed on the sliding plate 13. The guide post 6 plays a guiding role to ensure that the connecting plate 9 remains stable during the up and down sliding. In order to cope with possible abnormal situations during the test, especially the fire risk, a heat-sensitive glass 24 is installed inside the connecting plate 9. Once an abnormality occurs during the test, the heat-sensitive glass 24 will sense the high temperature and quickly break, thus releasing the connection with the limit ball 23. At this time, the spring 22 will immediately rebound, driving the limit ball 23 to move upward along the inside of the connecting plate 9, and then triggering the dry powder fire extinguishing agent in the device main body 1 to be quickly and accurately sprayed onto the core of the fire source through the fire extinguishing pipe 7, achieving efficient fire extinguishing, effectively curbing the spread of the fire, ensuring the safety of the test environment, and thus reducing the risk of fire accidents during the battery test.

[0042] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
