Description
Technical Field
[0001] This utility model relates to the field of electronic testing and measurement technology, and in particular to an integrated testing device for the conductivity and deformation of metal components in mobile phones. Background Technology
[0002] Mobile phones are an indispensable mobile communication device in modern life. They are not only used for communication but also integrate multiple functions, becoming an important tool for people's daily lives, work, and entertainment. With the development of technology, modern mobile phones have many functions, such as taking pictures, accessing the internet, making payments, and navigation, hence they are also called "smartphones."
[0003] In the mobile phone manufacturing process, the charging port is an important connecting component, and its conductivity directly affects the phone's charging, data transmission, and other functions.
[0004] Traditional tail plug continuity testing relies mainly on manual operation, which is inefficient and prone to missed detections. In addition, the metal contacts and connecting circuits inside the tail plug may have poor continuity due to poor soldering or the introduction of impurities during the manufacturing process.
[0005] Current mobile phone charging port testing mainly involves inserting the testing head of a testing instrument into the charging port and observing whether the testing light on the instrument illuminates. However, the charging port is easily deformed due to external forces such as mechanical impact during the production process. Currently, simply detecting whether it is conductive has low accuracy, and the charging port is not protected during the testing process. It is easily deformed by insertion and extraction forces, affecting its subsequent normal function. Utility Model Content
[0006] The main purpose of this utility model is to provide an integrated testing device for the conductivity and deformation of metal components in mobile phones, aiming to solve the technical problems in the prior art.
[0007] This utility model proposes an integrated testing device for the continuity and deformation of metal components in mobile phones. It includes a workbench, a controller, an integrated continuity and deformation testing device for testing the continuity and deformation of the phone's charging port, and a test drive device located on top of the workbench for detection. The integrated continuity and deformation testing device includes a continuity testing component, a buffer to prevent hard plugging, and a deformation testing component. The continuity testing component includes a continuity testing head and a USB male connector for connecting to the phone's charging port. The deformation testing component is located inside the continuity testing head, and the continuity testing head's lead wire is electrically connected to the USB male connector.
[0008] Preferably, the anti-hard insertion buffer includes a buffer fixing seat, a test seat, a buffer spring, and a buffer guide rod. The buffer fixing seat is located on one side of the test seat. The buffer fixing seat has symmetrical buffer grooves on its outer wall near the test seat. The test seat has a buffer through hole corresponding to the position of the buffer groove. The buffer guide rod is T-shaped. One end of the buffer guide rod extends through the two buffer through holes to its outer side. One end of the buffer spring is connected to the inner circumferential wall of the buffer groove, and the other end of the buffer spring is connected to the outer circumferential wall of the buffer guide rod inside the buffer through hole.
[0009] Preferably, the end of the continuity test head away from the USB male connector extends through the test socket to its outside.
[0010] Preferably, the deformation test piece includes strain gauges, and symmetrically arranged embedding grooves are provided on the inner walls of both sides of the continuity test head. The strain gauges are embedded in the embedding grooves, and each strain gauge is connected to a signal conditioning circuit board through a lead wire. The signal conditioning circuit board is electrically connected to the controller through a wire.
[0011] Preferably, the test drive device includes a guide rod, an electric telescopic rod, a sliding block, a mobile phone placement plate, and a test fixing plate for fixing the integrated continuity and deformation test device, all located on the top of the workbench. The guide rod is symmetrically installed on the top of the workbench, and the sliding block is symmetrically slidably installed on the two guide rods. The mobile phone placement plate is connected to the top of one of the sliding blocks, and the test fixing plate is connected to the top of the other sliding block on one side of the mobile phone placement plate. The electric telescopic rod is located between the two guide rods at one end of the workbench and is connected to the outer wall of the test fixing plate at the end away from the mobile phone placement plate.
[0012] Preferably, when the bottom of the buffer fixing base is fixed to the top of the test fixing plate by bolts, the conduction test head and the mobile phone tail plug hole are on the same straight line.
[0013] Preferably, the USB male connector is connected to an external power supply device, and the external power supply device is electrically connected to the controller.
[0014] Preferably, the controller is equipped with a deformation alarm buzzer connected by a wire.
[0015] The beneficial effects of this utility model are as follows:
[0016] This invention integrates continuity testing and deformation detection into one unit, reducing the number and complexity of testing equipment and lowering equipment procurement and maintenance costs. By monitoring the deformation of the tail plug in real time through strain gauges, combined with continuity testing, the quality of the tail plug can be comprehensively evaluated. The strain gauges are embedded in the embedding grooves on the inner wall of the continuity testing head, which can accurately measure the minute deformation of the tail plug, and the detection accuracy is far higher than that of traditional methods.
[0017] The combined design of the buffer mounting base, buffer spring, and buffer guide rod can effectively absorb the impact force during the insertion and removal process, reduce the deformation of the tail plug caused by hard insertion and removal, and further reduce the mechanical damage to the tail plug during the insertion and removal process.
[0018] The automated operation achieved through the electric telescopic rod and guide rod enables the insertion and removal of the tail plug quickly and accurately, significantly improving detection efficiency.
[0019] The controller performs real-time analysis of the received strain signals and can monitor the continuity and deformation status of the tail plug in real time. When the deformation of the tail plug exceeds the set threshold, the controller triggers an alarm buzzer to promptly remind the operator. Traditional detection methods rely on manual observation, which is prone to missed detections and misjudgments. This device significantly reduces detection errors caused by human factors through automation and high-precision detection. Through buffer protection and high-precision detection, it can promptly detect potential problems with the tail plug and avoid early damage caused by deformation or poor continuity.

[0031] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0032] All devices in this application adopt conventional models in the prior art, and the control method is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the field, so this application will not explain it in detail.
[0033] like Figures 1-8As shown, this application provides an integrated testing device for the continuity and deformation of metal components in mobile phones. It includes a workbench 1 supporting the entire testing device, a controller, and an integrated continuity and deformation testing device 2 for testing the continuity and deformation of the mobile phone's charging port. The controller controls the testing process and processes test data. The integrated continuity and deformation testing device 2 includes a continuity testing component 21, an anti-hard-plug buffer 22, and a deformation testing component 23. The continuity testing component 21 includes a continuity testing head 211 and a USB male connector 212 for connecting to the mobile phone's charging port. The continuity testing head 211 has a lead wire electrically connected to the USB male connector 212. The continuity testing head 211 is used to detect the contact status of the mobile phone's charging port to ensure stable connection. The USB male connector 212 is used to transmit data and supply power to the continuity testing head 211 to ensure testing accuracy. The deformation testing component 23 includes strain gauges 231. Embedded grooves 213 are symmetrically formed on the inner walls of both sides of the continuity testing head 211. Strain gauge 231 is embedded inside the embedding groove 213. The embedding groove 213 is used to embed and install the strain gauge 231. The strain gauge 231 is set on the inner walls of both sides of the continuity test head 211 and will not interfere with the contact of the continuity test head 211, ensuring the accuracy of the test data. The strain gauge 231 is a semiconductor chip. Semiconductor chips have high sensitivity and are suitable for measuring large deformations. The strain gauge 231 is embedded and pasted into the embedding groove 213 on the inner wall of the detection head using an adhesive such as epoxy resin. During pasting, the strain gauge 231 is tightly attached to the inner wall surface of the embedding groove 213 without air bubbles or impurities. Each strain gauge 231 is connected to a signal conditioning circuit board through a lead wire. A shielded wire is used to connect the lead wire of the strain gauge 231 to the signal conditioning circuit board to reduce signal interference. The signal conditioning circuit board then transmits the processed signal to the controller. The controller analyzes the deformation degree of the tail plug component based on the signal change to ensure the accuracy and reliability of the test results. A deformation alarm buzzer is connected to the controller through a wire.
[0034] The USB male connector 212 connects to an external power supply to provide power to the continuity test head 211. The continuity test head 211 is then inserted into the phone's charging port. The continuity test head 211 is electrically connected to the USB male connector 212 via a wire to check the contact of the charging port and ensure a stable connection. The continuity test result is transmitted to the controller via the USB male connector 212. The controller analyzes the received data to determine if the charging port is conductive. When the continuity test head 211 is inserted into the charging port, the strain gauge 231 detects the deformation of the charging port. Its resistance value changes with the deformation. The signal conditioning circuit board amplifies and filters the received strain signal to reduce signal interference. The processed signal is transmitted to the controller via a wire. The controller analyzes the degree of deformation of the charging port based on the signal changes. If the deformation exceeds a preset threshold, a deformation alarm buzzer sounds immediately to remind the operator to adjust in time, avoiding connection failure due to excessive deformation. This ensures the overall stability and safety of the testing system, improves testing efficiency, and guarantees the reliability of the phone's charging port during use.
[0035] like Figure 2 , Figure 3 and Figure 4 As shown, the anti-hard insertion / removal buffer 22 includes a buffer fixing base 221, a test base 222, a buffer spring 223, and a buffer guide rod 224. The end of the conductive test head 211 away from the USB male connector 212 extends through the test base 222 to its exterior. The buffer fixing base 221 is located on one side of the test base 222 and is used to fix it to the test fixing plate 35, providing a stable mounting base. symmetrical buffer grooves 225 are formed on the outer wall of the buffer fixing base 221 near the test base 222. A buffer through hole 226 corresponding to the position of the buffer groove 225 is formed inside the test base 222. The buffer guide rod 224 is T-shaped, and one end of the buffer guide rod 224 passes through two buffer through holes. The hole 226 extends to its outer edge. One end of the buffer spring 223 is connected to the inner circumferential wall of the buffer groove 225, and the other end of the buffer spring 223 is connected to the outer circumferential wall of the buffer guide rod 224 inside the buffer through hole 226. The length of the buffer guide rod 224 is less than the length of the buffer spring 223. When the buffer spring 223 is compressed and deformed, the buffer guide rod 224 slides in the buffer through hole 226, limiting the compression of the buffer spring 223 and preventing damage due to excessive compression. The buffer spring 223 provides elastic cushioning and flexible connection, absorbing the impact force during the insertion and removal process. The buffer guide rod ensures the stable extension and contraction of the spring and prevents deviation, thereby realizing the dual functions of cushioning and guiding, enhancing the smoothness during the insertion and removal process, extending the service life, and ensuring the accuracy and safety of each connection.
[0036] The buffer mounting base 221 is located on one side of the test base 222, providing stable support for the entire buffer assembly. Symmetrical buffer grooves 225 are formed on its outer wall near the test base 222 for installing buffer springs 223. A buffer through hole 226 is formed inside the test base 222, corresponding to the position of the buffer groove 225, to accommodate the buffer guide rod 224. The end of the conduction test head 211 away from the USB male connector 212 extends through the test base 222 to its outside, ensuring accurate insertion of the test head into the phone's charging port. One end of the buffer spring 223 is connected to the inner circumferential wall of the buffer groove 225, and the other end is connected to the outer circumferential wall of the buffer guide rod 224 inside the buffer through hole 226. When the conduction test head 211 is inserted or removed... When the phone's charging port is inserted, the buffer spring provides elastic cushioning, absorbing the insertion and extraction force and reducing the impact on the charging port. The buffer guide rod 224 is T-shaped, with one end extending through the two buffer through holes 226 to the outside, cooperating with the buffer spring 223 to ensure the stable extension and contraction of the spring and prevent displacement during insertion and extraction. The buffer spring 223 can effectively absorb the impact force during insertion and extraction, reducing the deformation and damage to the charging port caused by hard insertion and extraction. The buffer guide rod 224 ensures the stable extension and contraction of the spring, further improving the cushioning effect and protecting the charging port from mechanical damage. The anti-hard insertion and extraction buffer component, through technological integration, achieves buffer protection for the phone's charging port, reduces mechanical damage during insertion and extraction, and improves testing accuracy and the service life of the charging port.
[0037] like Figure 1 , Figure 7 and Figure 8As shown, the top of the workbench 1 houses a test drive device 3 for detection. The test drive device 3 includes guide rods 31, an electric telescopic rod 32, sliding blocks 33, a mobile phone placement plate 34, and a test fixing plate 35 for fixing the integrated continuity and deformation test device 2. The guide rods 31 are symmetrically installed on the top of the workbench 1, and the sliding blocks 33 are symmetrically slidably installed on the two guide rods 31. The guide rods 31 provide a stable sliding path, and the sliding blocks 33 slide along the guide rods 31, ensuring precise movement of the test device. The mobile phone placement plate 34 is connected to the top of one of the sliding blocks 33, and the test fixing plate 35 is connected to the top of the other sliding block 33 on one side of the mobile phone placement plate 34. The electric telescopic rod 32 is located between the two guide rods 31 at one end of the workbench 1. The electric telescopic rod 32 is connected to the outer wall of the end of the test fixing plate 35 away from the mobile phone placement plate 34. The electric telescopic rod 32 provides power, and the test fixing plate 35 fixes the integrated continuity and deformation testing device 2 to ensure the stability of the testing process. The bottom of the buffer fixing seat 221 is fixed to the test fixing plate 3 by bolts. When the phone is at the top, the continuity test head 211 is aligned with the phone's tail plug hole. The phone placement plate 34 is used to fix the phone under test. The movement of the sliding block 22 drives the phone placement plate 34 to achieve precise positioning of the phone. The position of the phone placement plate 34 can be limited by screws to prevent displacement. When the phone under test is placed on the phone placement plate 34, the controller issues a command, and the electric telescopic rod 32 extends and retracts, pushing the test fixing plate 35 to move along the guide rod 31. The continuity test head 211 is inserted into the phone's tail plug hole to perform continuity and deformation tests. After the test is completed, the electric telescopic rod 32 extends and retracts in the opposite direction to pull the continuity test head 211 out of the tail plug hole. The cooperation between guide rod 31 and sliding block 33 ensures the linear movement of the testing device, improving testing accuracy. Electric telescopic rod 32 provides stable power, ensuring smooth movement of the testing device. The controller controls the extension and retraction of the electric telescopic rod, achieving automated operation, reducing manual intervention, and improving testing efficiency. Automated operation reduces testing time and improves production efficiency. Precise positioning reduces repetitive testing due to positional deviations, further improving efficiency. The testing drive device, through technological integration, achieves precise driving and positioning of the integrated continuity and deformation testing device 2, improving testing accuracy and efficiency. This design not only reduces production costs but also enhances the user experience, representing a significant innovation in mobile phone tail plug testing technology.
