Description

Technical Field

[0001] This utility model relates to the field of battery measurement technology, specifically a device for accurately measuring the thickness of a button battery. Background Technology

[0002] A button battery is a small, flat, round battery that resembles a button or coin. It typically consists of a positive electrode, an internal electrode, and a negative electrode. Button batteries are characterized by their small size, stable voltage, and high energy density. They are widely used in various small and portable electronic devices, and their core function is to provide stable and long-lasting power to microelectronic devices.

[0003] An investigation revealed a utility model patent (publication number: CN219434007U) disclosing a battery thickness measuring device. The device comprises a conveyor line and a thickness measuring assembly. The conveyor line includes a servo motor, a drive pulley, a driven pulley, a transmission belt, a first tension pulley, and a second tension pulley. The output end of the servo motor is connected to the input shaft of a reducer. The reducer is mounted on a first support plate, and a first synchronous pulley is mounted on the output shaft of the reducer. The first synchronous pulley is connected to a second synchronous pulley via a synchronous belt. The second synchronous pulley is mounted at one end of a drive shaft, on which a drive pulley is mounted, and on which a driven pulley is mounted. This utility model reads the readings from a grating ruler located on one side of the reading head. The average of the readings from the two reading heads is used to obtain the thickness of the battery under test. This achieves automated detection of the battery thickness, improving the accuracy and efficiency of battery thickness measurement and reducing the operator's workload.

[0004] In the above technical solution, the battery is transported to the measurement station by the cooperation of the conveyor line and the thickness measuring component, and the thickness data is obtained non-contactly by using advanced optical measurement technology (grating ruler). The device as a whole involves multiple structures such as the conveyor line, including servo motor, drive wheel, driven wheel, transmission belt and thickness measuring component, which are inconvenient to carry and move. At the same time, the battery is prone to positional displacement when it is delivered under the pressure block during the measurement process, which affects the accuracy of the measurement work.

[0005] Therefore, this invention provides a device for accurately measuring the thickness of button batteries to solve the above problems. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This invention provides a device for accurately measuring the thickness of button batteries, such as... Figure 1 , Figure 3 and Figure 4As shown, the device includes a base structure 1, which includes a measuring platform 101 and a fixing ring 102. Fixing structures 2 are installed on both sides of the measuring platform 101. Each fixing structure 2 includes a motor 201 and an electric push rod 202. One end of the electric push rod 202 is connected to a clamp 205. A connecting structure 3 is connected inside the fixing ring 102. The connecting structure 3 includes a connecting rod 301, a fastening spring 302, and a limiting post 303. A connecting plate 304 is installed on the top of the connecting rod 301. A thickness measuring component 4 is installed on the top of the connecting plate 304. The thickness measuring component 4 includes an equipment box 401 and a measuring instrument 403.

[0028] The measuring platform 101 in the base structure 1 has symmetrical fixed rings 102 on both sides of the top. The fixed rings 102 are all circular. The measuring platform 101 has bases fixedly installed on both sides of the top.

[0029] In the fixed structure 2, the motor 201 is fixedly installed outside the base. The output end of the motor 201 is connected to one end of the electric push rod 202. The other end of the electric push rod 202 is installed on the outer wall of the connector 203. Clamps 205 are movably installed on both sides of the outer wall of the connector 203. The two clamps 205 are connected by a threaded rod 204.

[0030] When using the device, the operator places the button battery to be tested on the measuring platform 101. The motor 201 starts, driving the electric push rod 202 to extend or adjust its angle, moving the end clamp 205 above or to the side of the battery. The electric push rod 202 pushes the clamp 205 downward or inward, pressing the battery firmly onto the measuring platform 101 to prevent it from moving during measurement, thus improving the efficiency of the measurement work. The thickness measuring component 4 is mounted on the fixing ring 102 through the connecting structure 3. The connecting rod 301 and the fastening spring 302 provide suspension and a certain amount of cushioning. Pressing down the connecting plate 304 compresses the fastening spring 302, thereby lowering the entire thickness measuring component 4. When the thickness measuring component 4 lowers, the measuring instrument 403... The probe at the bottom contacts the battery surface. The sensing mechanism inside the measuring instrument 403 detects the displacement of the probe. The measuring instrument 403 converts the detected displacement signal into thickness data and displays it on its external digital display screen. The operator reads the value on the display screen, which is the thickness of the battery. After the measurement is completed, the operator releases the downward pressure. The rebound force of the fastening spring 302 pushes the thickness measuring component 4 back to its initial height, away from the battery surface, so that the battery can be removed.

[0031] Furthermore, in order to improve the working efficiency of the device, such as Figure 2 and Figure 5As shown, the bottom of the connecting rod 301 in the connecting structure 3 is fixedly connected to the inside of the fixing ring 102. The connecting rod 301 extends to the top of the connecting plate 304 and is fixed by the limiting post 303. A fastening spring 302 is movably sleeved on the outside of the connecting rod 301.

[0032] The equipment box 401 in the thickness measurement assembly 4 is fixed to the top center of the connecting plate 304 by the mounting plate 406. The measuring instrument 403 is connected to the outside of the equipment box 401. The sensor 402 is installed on the top of the measuring instrument 403. The measuring instrument 403 is equipped with a digital display screen and buttons.

[0033] The thickness measuring assembly 4 also includes a telescopic rod 404 and a probe positioning block 405. One end of the telescopic rod 404 is electrically connected to the inside of the measuring instrument 403, and the other end of the telescopic rod 404 is connected to the probe positioning block 405.

[0034] When in use, the measuring instrument 403 is the core measuring unit. When its probe positioning block 405 contacts the battery, the internal sensor 402 detects the displacement change. The internal circuit of the measuring instrument 403 converts the analog signal detected by the sensor 402 into a digital signal, calculates and processes it to obtain the thickness value, and finally displays it on its external digital display screen. The telescopic rod 404 is driven by the internal power supply of the measuring instrument 403 to extend and retract. The probe positioning block 405 is fixed at the end of the telescopic rod 404. The measuring instrument 403 controls the telescopic rod 404 to extend downward, pushing the probe positioning block 405 and the probe on it to contact the battery. After the measurement is completed, the telescopic rod 404 retracts, driving the probe away from the battery surface, completing the measurement work. By setting independent components, the whole device is easy to install, disassemble and carry quickly, improving the efficiency of the device.

[0035] 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.
