Description

Technical Field

[0001] The utility model belongs to the technical field of battery detection, and specifically relates to a safety detection device for battery production. Background Art

[0002] A battery is a device that converts chemical energy into electrical energy. It usually consists of a positive electrode, a negative electrode, an electrolyte, and a casing; ions are transported between the positive and negative electrodes through the electrolyte to generate an electric current; different types of batteries have different characteristics. For example, dry batteries are easy to carry but have relatively less power; lithium batteries have a high energy density and are widely used in fields such as electronic products and electric vehicles; at the end of battery production, various data of the battery need to be detected and collected, and it can only be put into use after passing the detection. Therefore, a safety detection device is generally used to perform safety detection on the produced batteries.

[0003] A battery safety detection device usually consists of the following structures: a detection probe, a data acquisition module, a control unit, and a display interface; the detection probe is used to contact the battery and collect relevant data; the data acquisition module processes and converts the data obtained by the probe; the control unit is the core part, responsible for analyzing the data and making a judgment; the display interface intuitively displays the detection result; its principle is to measure parameters such as the voltage, current, and temperature of the battery through the detection probe. The control unit compares these parameters with preset safety standards, and if they exceed the range, an alarm is issued.

[0004] Although the existing battery safety detection devices can detect the voltage, current, and temperature of the battery, they are insufficient in simulating extreme weather conditions. As a result, when detecting the parameter data of the battery in high-temperature or low-temperature weather, the estimation is not accurate enough, which may lead to certain safety hazards when the battery is put into use; moreover, the existing battery safety detection devices are insufficient in detecting the pressure on the battery casing, resulting in inaccurate parameters and affecting the use of the battery. Therefore, a safety detection device for battery production is proposed to address the above problems. Summary of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology and address the problems of the existing equipment, the utility model proposes a safety detection device for battery production.

[0006] The technical solution adopted by the present utility model to solve its technical problems is a safety detection device for battery production, including a detection box. One side of the detection box is provided with a control panel, which is signal-connected to a motor. The output end of the motor is connected to a threaded rod, and the outside of the threaded rod is rotatably connected to a threaded tube. The inside of the threaded tube is provided with a threaded groove, and the diameter of the threaded groove is the same as that of the threaded rod. The outside of the threaded tube is fixedly connected to a detection table, the bottom of the detection table is provided with a support plate, the bottom of the support plate is provided with a base, and the bottom of the base is connected to the inner wall of the detection box. The top of the detection box is provided with a sealing door. The top of the detection box is provided with a temperature regulator, and the output end of the temperature regulator is connected to a temperature regulating wire. By using a temperature regulator of model WZPK-236S to simulate the temperature inside the device and at the same time to test the performance of the battery under different temperatures, it can avoid the deficiency in simulating extreme weather, which may lead to inaccurate estimation of the parameter detection data of the battery in high-temperature or low-temperature weather, and thus cause certain potential safety hazards when the battery is put into use.

[0007] Preferably, a detection frame is arranged inside the temperature regulating wire. Fifty to one hundred groups of ventilation openings are arranged on the surface of the detection frame. Through holes are arranged on both sides of the detection frame. A top rod is slidably connected inside the through holes. A through hole is arranged at the bottom of the top rod, and a threaded hole is arranged inside the through hole at the bottom of the top rod. The top rod is rotatably connected to the threaded rod. By adding a clamping structure design on both sides of the device, the battery can be clamped by the motors on both sides to the central clamping plate, so that the outer shell of the battery can be squeezed and detected while the battery data is detected, thus avoiding inaccurate parameters and affecting the use of the battery.

[0008] Preferably, the two sides of the detection frame are symmetrically designed. The detection table is placed inside the detection frame. An exhaust fan is arranged on one side of the detection box, and the exhaust fan is communicated with the detection frame. The other end of the top rod is fixedly connected to a clamping plate, and the clamping plate is placed inside the detection frame. With this structural design, the ventilation effect of the device is increased by adding an exhaust fan on one side of the device, thereby improving the detection efficiency. And by adding a clamping plate at the other end of the top rod, the contact area between the clamping structure and the battery is increased, and the bearing effect of the pressure is increased in this way, making the pressure detection data more accurate. And by arranging the clamping plate inside the detection frame, the contact distance between the clamping plate and the temperature regulating wire can be increased, thus avoiding the high temperature of the temperature regulating wire during heating from affecting the strength of the clamping plate itself and causing the pressure detection data to be affected.

[0009] The advantages of the present utility model are as follows:

[0010] This utility model simulates the temperature inside the device by using a thermostat, and at the same time tests the battery's performance at different temperatures, thus avoiding deficiencies in simulating extreme weather, which may lead to inaccurate estimation of parameter detection data when the battery is in high-temperature or low-temperature weather, and thus cause certain potential safety hazards when the battery is put into use; by adding a clamping structure design on both sides of the device, the battery can be clamped by the motors on both sides to the central clamping plate, so that while detecting the battery data, the outer shell of the battery can be squeezed and detected, thus avoiding inaccurate parameters and affecting the use of the battery.

[0019] Please refer toFigures 1-5 As shown in the figure, a safety detection device for battery production includes a detection box 1. One side of the detection box 1 is provided with a control panel 3, and the control panel 3 is signal-connected to a motor 9. The output end of the motor 9 is connected to a threaded rod 11. The outside of the threaded rod 11 is rotatably connected to a threaded tube 16. The inside of the threaded tube 16 is provided with a threaded groove 18, and the caliber of the threaded groove 18 is the same as that of the threaded rod 11. The outside of the threaded tube 16 is fixedly connected to a detection table 12. The bottom of the detection table 12 is provided with a support plate 8, and the bottom of the support plate 8 is provided with a base 13. The bottom of the base 13 is connected to the inner wall of the detection box 1. The top of the detection box 1 is provided with a sealing door 5. The top of the detection box 1 is provided with a temperature regulator 4, and the output end of the temperature regulator 4 is connected to a temperature regulating wire 7. Inside the temperature regulating wire 7 is provided with a detection frame 6. The surface of the detection frame 6 is provided with fifty to one hundred groups of ventilation openings 15. Both sides of the detection frame 6 are provided with dug holes 14. When using this safety detection device to simulate the usage data of the battery at different temperatures, first, the operator places the battery on the detection table 12, and then starts the temperature regulating box 4. At this time, under the action of the temperature regulating box 4, heat begins to condense on the temperature regulating wire 7, and then the heat is dissipated through the temperature regulating wire 7, and the battery inside the detection frame 6 is heated thereby to perform a heating treatment on the battery. After that, the operator pulls the sealing door 5 to seal the device. After a period of heating, data statistics can be started, thereby completing the detection operation of the working state of the battery at a specific temperature. When the detection is over, the heat will be discharged from the device by the rotation of the exhaust fan 2 on one side. Then, the sealing door 5 can be opened to take out the battery and complete the operation. After that, the clamping structure can be driven by starting the motor 9 to perform a pressure test on the outer shell of the battery.

[0020] A ejector rod 10 is slidably connected inside the dug hole 14. A perforation is formed at the bottom of the ejector rod 10, and a threaded hole is provided inside the perforation at the bottom of the ejector rod 10. The ejector rod 10 is rotatably connected to a threaded rod 11; both sides of the detection frame 6 are designed in a symmetrical structure; the detection table 12 is placed inside the detection frame 6; an exhaust fan 2 is provided on one side of the detection box 1, and the exhaust fan 2 communicates with the detection frame 6; the other end of the ejector rod 10 is fixedly connected to a clamping plate 17, and the clamping plate 17 is placed inside the detection frame 6; when detecting the pressure of the battery shell, at this time, the operator starts the motor 9 by operating the control panel 3. At this time, the motors 9 located on both sides of the detection table 12 will drive the threaded rod 11 to rotate. At the same time, the ejector rod 10 located outside the threaded rod 11 will move horizontally along the thread of the thread groove 18 with the assistance of the threaded tube 16. Then, in this way, the clamping plate 17 at its other end will be retracted, and the outer shell of the battery will be clamped in this way, so as to detect the pressure bearing coefficient of the battery shell. Similarly, the pressure bearing effect of the battery shell in a special environment can be detected by starting the thermostat 4 to heat the detection box 1 when clamping and detecting the pressure, so as to increase the accuracy of the detection data; only by observing various parameters displayed on the control panel 3 can the pressure parameters of the battery and its working conditions in a special environment be evaluated, so as to complete the safety detection operation of battery production.

[0021] Working principle: When using this safety detection device to simulate the usage data of the battery at different temperatures, first, the operator places the battery on the detection table 12, and then starts the temperature control box 4. At this time, under the action of the temperature control box 4, heat begins to condense on the temperature control wire 7, and then the heat is dissipated through the temperature control wire 7, and the battery inside the detection frame 6 is heated accordingly, so as to heat-treat the battery. After that, the operator pulls the sealing door 5 to seal the device. After heating for a period of time, data statistics can be started, so as to complete the detection operation of the working state of the battery at a special temperature; when the detection is over, the heat will be discharged from the device by the rotation of the exhaust fan 2 on one side. After that, the sealing door 5 can be opened to take out the battery and complete the operation; when detecting the pressure of the battery shell, at this time, the operator starts the motor 9 by operating the control panel 3. At this time, the motors 9 located on both sides of the detection table 12 will drive the threaded rod 11 to rotate. At the same time, the ejector rod 10 located outside the threaded rod 11 will move horizontally along the thread of the thread groove 18 with the assistance of the threaded tube 16. Then, in this way, the clamping plate 17 at its other end will be retracted, and the outer shell of the battery will be clamped in this way, so as to detect the pressure bearing coefficient of the battery shell. Similarly, the pressure bearing effect of the battery shell in a special environment can be detected by starting the thermostat 4 to heat the detection box 1 when clamping and detecting the pressure, so as to increase the accuracy of the detection data.
