Description

Technical Field

[0001] This utility model relates to the field of battery bulging detection, and in particular to a battery bulging detector. Background Technology

[0002] Mobile phones have long been an indispensable part of our lives, and whether a mobile phone battery is bulging is a very important part of the battery manufacturer's factory testing.

[0003] Currently, battery bulging is generally detected by direct observation or by measuring battery capacity, which cannot accurately determine whether a battery is bulging. Utility Model Content

[0004] In view of the above problems, this application provides a battery bulging detector to solve the technical problem that it is impossible to accurately determine whether a battery is bulging by directly observing or measuring the battery capacity.

[0005] To achieve the above objectives, the inventors provide a battery bulge detector, comprising:

[0006] The battery mechanism includes the battery to be tested and a battery holder, with the battery to be tested mounted on the battery holder.

[0007] The transducer mechanism includes a transmitting transducer, a receiving transducer, and a transducer mounting frame. The transmitting transducer and the receiving transducer are respectively mounted on the transducer mounting frame, and the battery to be tested is located between the transmitting transducer and the receiving transducer.

[0008] The moving mechanism includes a first moving component, which includes a first moving motor, a first moving guide rail, and a first moving slider. The output end of the first moving motor is connected to the first moving slider. The first moving guide rail extends along a first direction. The first moving slider is mounted on the first moving guide rail and is slidably connected to the first moving guide rail. The first moving slider is connected to a transducer mounting bracket. The first moving motor is used to drive the transducer mounting bracket to move along the first direction.

[0009] Unlike existing technologies, the technical solution of this application includes a battery holder to fix the battery to be tested, and a transmitting transducer and a receiving transducer are respectively arranged above and below the battery. Simultaneously, a moving mechanism controls the movement of the transducer holder, thereby moving the positions of the transmitting and receiving transducers to detect bulging in various parts of the battery. Therefore, by using ultrasound combined with the moving mechanism, it is possible to accurately detect whether the battery is bulging and to pinpoint the exact location of the bulge.

[0010] In one embodiment of this utility model, the moving mechanism further includes a second moving component, which includes a second moving motor, a second moving guide rail, and a second moving slider. The output end of the second moving motor is connected to the second moving slider. The second moving guide rail extends along a second direction. The second moving slider is mounted on the second moving guide rail and is slidably connected to the second moving guide rail. The second moving slider is connected to the first moving guide rail. The second moving motor is used to drive the transducer fixing frame to move along the second direction, wherein the second direction is perpendicular to the first direction.

[0011] Thus, the transducer holder can be driven to move along the second direction by the second moving component, thereby moving the transmitting transducer and the receiving transducer to the positions of the battery to be tested along the second direction to detect the bulging of various parts of the battery.

[0012] In one embodiment of this utility model, the moving mechanism further includes a third moving component, which includes a third moving motor, a third moving guide rail, and a third moving slider. The output end of the third moving motor is connected to the third moving slider. The third moving guide rail extends along a third direction. The third moving slider is mounted on the third moving guide rail and is slidably connected to the third moving guide rail. The third moving slider is connected to the second moving guide rail. The third moving motor is used to drive the transducer fixing frame to move along a third direction, wherein the third direction is perpendicular to the first direction and the second direction.

[0013] Thus, the transducer holder can be driven to move along a third direction by the third moving component, thereby moving the transmitting transducer and the receiving transducer to the position of the battery to be tested along the third direction, so as to detect the bulging of various parts of the battery.

[0014] In one embodiment of this utility model, two sets of third moving components are provided, with one set of third moving components installed at the front end and the rear end of the second moving guide rail.

[0015] In this way, by setting two sets of third moving components, the second moving component can be moved more stably, while also providing good support.

[0016] As one embodiment of this utility model, the battery bulge detector also includes a microcontroller, which is communicatively connected to the moving mechanism, and the microcontroller is communicatively connected to the transducer mechanism and the moving mechanism.

[0017] In this way, centralized control of the moving mechanism via a microcontroller makes it more convenient and flexible.

[0018] As one embodiment of this utility model, the battery bulge detector also includes a host computer, which is connected to the microcontroller via RS485 communication.

[0019] In this way, the microcontroller uploads the bulging data of various parts of the battery detected by the transducer mechanism to the host computer, and the host computer then analyzes whether the battery is bulging based on the bulging data.

[0020] As one embodiment of this utility model, the transducer mounting bracket includes a first plate, an intermediate plate and a second plate connected in sequence. The cross-section of the transducer mounting bracket is U-shaped. A transmitting transducer is installed on the first plate and a receiving transducer is installed on the second plate.

[0021] Thus, the U-shaped cross-section of the transducer mounting bracket allows for better installation of the transmitting and receiving transducers, and positions the transmitting and receiving transducers above or below the battery under test, resulting in a simple structure.

[0022] As one embodiment of this utility model, the transducer mechanism also includes a transmitting nut. A first hole is provided on the first plate, and the transmitting nut is fixedly installed at the first hole. The transmitting transducer is threadedly connected to the transmitting nut.

[0023] Thus, the transmitting transducer can be easily mounted on the first plate using the transmitting nut, and the position of the transmitting transducer relative to the battery to be tested in the first direction can be finely adjusted.

[0024] As one embodiment of this utility model, the transducer mechanism also includes a receiving nut, a second hole is provided on the second plate, the receiving nut is fixedly installed at the second hole, and the receiving transducer is threadedly connected to the receiving nut.

[0025] Thus, the receiving nut facilitates the mounting of the receiving transducer on the second plate, and the position of the receiving transducer relative to the battery to be tested in the first direction can be finely adjusted.

[0026] In one embodiment of this utility model, the distance between the transmitting transducer and the receiving transducer along the first direction is 80mm.

[0027] Therefore, it is preferable to set the distance between the transmitting transducer and the receiving transducer along the first direction to be 80mm.

[0048] According to some embodiments of this application, please refer to Figure 1This embodiment relates to a battery bulge detector 100, including a battery mechanism 1, a transducer mechanism 2, and a moving mechanism 3. The battery mechanism 1 includes a battery to be tested 11 and a battery mounting bracket 12, with the battery to be tested 11 mounted on the battery mounting bracket 12. The transducer mechanism 2 includes a transmitting transducer 21, a receiving transducer 22, and a transducer mounting bracket 23, with the transmitting transducer 21 and the receiving transducer 22 correspondingly mounted on the transducer mounting bracket 23, and the battery to be tested 11 located between the transmitting transducer 21 and the receiving transducer 22. The moving mechanism 3 includes... The first moving component 31 includes a first moving motor 311, a first moving guide rail 312, and a first moving slider 313. The output end of the first moving motor 311 is connected to the first moving slider 313. The first moving guide rail 312 extends along the first direction X. The first moving slider 313 is mounted on the first moving guide rail 312 and is slidably connected to the first moving guide rail 312. The first moving slider 313 is connected to the transducer mounting bracket 23. The first moving motor 311 is used to drive the transducer mounting bracket 23 to move along the first direction X.

[0049] The battery holder 12 includes a support frame and a clamping member installed in the middle of the support frame. The clamping member is used to clamp and fix the battery 11 to be tested.

[0050] The battery under test 11 is located between the transmitting transducer 21 and the receiving transducer 22. Optionally, the transmitting transducer 21 is positioned above the battery under test 11, and the receiving transducer 22 is positioned below the battery under test 11.

[0051] The first movable slider 313 is connected to the transducer mounting bracket 23. Specifically, the transducer mounting bracket 23 is detachably mounted on the first movable slider 313 by bolts, which facilitates installation and subsequent disassembly.

[0052] The technical solution of this application includes a battery holder 12 to fix the battery 11 to be tested, and a transmitting transducer 21 and a receiving transducer 22 are respectively arranged above and below the battery 11. Simultaneously, the transducer holder 23 can be moved by a moving mechanism 3, thereby moving the positions of the transmitting transducer 21 and the receiving transducer 22 to detect bulging in various parts of the battery. Therefore, by using ultrasound and the moving mechanism 3, it is possible to accurately detect whether the battery is bulging and to pinpoint the exact location of the bulge.

[0053] According to some embodiments of this application, optionally, such as Figure 1As shown, the moving mechanism 3 also includes a second moving component 32, which includes a second moving motor 321, a second moving guide rail 322, and a second moving slider 323. The output end of the second moving motor 321 is connected to the second moving slider 323. The second moving guide rail 322 extends along the second direction Y. The second moving slider 323 is mounted on the second moving guide rail 322 and is slidably connected to the second moving guide rail 322. The second moving slider 323 is connected to the first moving guide rail 312. The second moving motor 321 is used to drive the transducer mounting bracket 23 to move along the second direction Y, wherein the second direction Y is perpendicular to the first direction X.

[0054] The second movable slider 323 is connected to the first movable guide rail 312. Specifically, the first movable guide rail 312 can be detachably mounted on the second movable slider 323 via a first fixing member and bolts. Under the action of the second movable component 32, the position of the transducer mechanism 2 relative to the battery to be tested 11 along the first direction X and the second direction Y can be adjusted, thereby detecting the bulging condition of the battery to be tested 11 at different positions.

[0055] Thus, the transducer holder 23 can be driven to move along the second direction Y by the second moving component 32, thereby moving the transmitting transducer 21 and the receiving transducer 22 to the positions of the battery to be tested 11 along the second direction Y, so as to detect the bulging of various parts of the battery.

[0056] According to some embodiments of this application, optionally, the moving mechanism 3 further includes a third moving component 33, which includes a third moving motor 331, a third moving guide rail 332, and a third moving slider 333. The output end of the third moving motor 331 is connected to the third moving slider 333. The third moving guide rail 332 extends along a third direction Z. The third moving slider 333 is mounted on the third moving guide rail 332 and is slidably connected to the third moving guide rail 332. The third moving slider 333 is connected to the second moving guide rail 322. The third moving motor 331 is used to drive the transducer fixing frame 23 to move along a third direction Z, wherein the third direction Z is perpendicular to the first direction X and the second direction Y.

[0057] The third movable slider 333 is connected to the second movable guide rail 322. Specifically, the second movable guide rail 322 can be detachably mounted on the third movable slider 333 via a second fixing member and bolts. Under the action of the third movable component 33, the position of the transducer mechanism 2 relative to the battery under test 11 along the first direction X, the second direction Y, and the third direction Z can be adjusted to further detect the bulging condition of the battery under test 11 at different positions.

[0058] Thus, the transducer holder 23 can be driven to move along the third direction Z by the third moving component 33, thereby moving the transmitting transducer 21 and the receiving transducer 22 to the position of the battery to be tested 11 along the third direction Z, so as to detect the bulging of various parts of the battery.

[0059] According to some embodiments of this application, optionally, such as Figure 1 As shown, there are two sets of the third moving component 33, with one set of the third moving component 33 installed at the front end and the rear end of the second moving guide rail 322.

[0060] The front and rear ends of the second moving guide rail 322 are Figure 1 The direction along the second direction Y is called the front end, and its opposite direction is called the back end.

[0061] Thus, by setting two sets of third moving components 33, the second moving component 32 can be moved more stably, while also providing good support.

[0062] According to some embodiments of this application, optionally, such as Figure 3 As shown, the battery bulge detector 100 also includes a microcontroller, which is communicatively connected to the moving mechanism 3, and is also communicatively connected to the transducer mechanism 2 and the moving mechanism 3.

[0063] A 24V DC power supply powers the microcontroller, which includes a data acquisition and control host and a control console. The data acquisition and control host is connected to the control console. The data acquisition and control host controls the transducer mechanism 2, and the control console controls the moving mechanism 3. This centralized control of the moving mechanism 3 via the microcontroller provides greater convenience and flexibility.

[0064] According to some embodiments of this application, optionally, such as Figure 4 and Figure 5 As shown, the battery bulge detector 100 also includes a host computer, which is connected to the microcontroller via RS485 communication.

[0065] In actual testing, the battery bulge detector 100 employs a dual-transducer ultrasonic method, with one transducer transmitting and the other receiving. Both transducers are fixedly mounted on the moving mechanism 3 via a transducer mounting bracket 23. The sampling point of the battery 11 under test is located by changing the positions in the second direction (Y) and the third direction (Z) through a microcontroller's control console. The receiving transducer 22 receives the signal emitted by the transmitting transducer 21. The data is transmitted to the host computer via RS485 through the microcontroller's acquisition control host. The host computer receives and analyzes the signal. If the signal is greater than a threshold, a dark dot is displayed, indicating that the battery is intact and has no bulge; if the signal is less than the threshold, a light-colored dot is displayed, indicating that the battery sampling point is bulging. After sampling one point, the control console automatically changes the positioning positions in the second direction (Y) and the third direction (Z) to judge the signal of the next point. Thus, by changing the program on the control console, different numbers of sampling points can be performed, such as 1 point, 2 points, 3 points, 2*2, 2*3, 3*4, 4*4, and 5*8. Specifically, the battery 11 to be tested can be virtually divided into many detection points according to its shape for data detection. The detected data is then uploaded to the host computer for combination and drawing of graphics, and finally it is determined whether the battery is bulging and the specific location of the bulge.

[0066] For example, when the mobile phone battery is a polymer lithium 3.7V battery with dimensions of 4.8mm*67mm*89mm, the installation distance between the transmitting transducer 21 and the receiving transducer 22 along the first direction X can be set to 80mm, and 40 collection points (5*8) can be set to detect battery bulging.

[0067] In this way, the microcontroller uploads the bulging data of various parts of the battery detected by the transducer mechanism 2 to the host computer, and the host computer then analyzes whether the battery is bulging based on the bulging data.

[0068] According to some embodiments of this application, optionally, such as Figure 1 and Figure 2 As shown, the transducer mounting bracket 23 includes a first plate 231, an intermediate plate 232 and a second plate 233 connected in sequence. The cross-section of the transducer mounting bracket 23 is U-shaped. A transmitting transducer 21 is installed on the first plate 231 and a receiving transducer 22 is installed on the second plate 233.

[0069] The intermediate plate 232 can be detachably mounted on the first movable slider 313 by bolts.

[0070] Thus, the U-shaped cross-section of the transducer mounting bracket 23 allows for better installation of the transmitting transducer 21 and the receiving transducer 22, and positions the transmitting transducer 21 and the receiving transducer 22 above or below the battery 11 to be tested, resulting in a simple structure.

[0071] According to some embodiments of this application, optionally, such as Figure 1 and Figure 2 As shown, the transducer mechanism 2 also includes a transmitting nut 24. A first hole is provided on the first plate 231, and the transmitting nut 24 is fixedly installed at the first hole. The transmitting transducer 21 is threadedly connected to the transmitting nut 24.

[0072] Thus, the transmitting transducer 21 can be easily mounted on the first plate 231 by means of the transmitting nut 24, and the position of the transmitting transducer 21 relative to the battery to be tested 11 in the first direction X can be finely adjusted.

[0073] According to some embodiments of this application, optionally, such as Figure 1 and Figure 2 As shown, the transducer mechanism 2 also includes a receiving nut 25. A second hole is provided on the second plate 233. The receiving nut 25 is fixedly installed at the second hole. The receiving transducer 22 is threadedly connected to the receiving nut 25.

[0074] The second hole is positioned corresponding to the first hole. Thus, the receiving nut 25 facilitates the mounting of the receiving transducer 22 onto the second plate 233, and allows for fine-tuning of the position of the receiving transducer 22 relative to the battery 11 to be tested in the first direction X.

[0075] According to some embodiments of this application, optionally, the distance between the transmitting transducer 21 and the receiving transducer 22 along the first direction X is 80 mm.

[0076] Therefore, it is preferable to set the distance between the transmitting transducer 21 and the receiving transducer 22 along the first direction X to be 80 mm. In some embodiments, the installation distance can be adjusted according to the area of ​​the battery 11 to be tested.
