Description

Technical Field

[0001] This invention relates to the field of signal diagnostic testing technology, and in particular to a touch screen signal acquisition and fault diagnosis testing device. Background Technology

[0002] A touchscreen is a sensory display device that can receive input signals from touch points, etc. It enables human-computer interaction by touching the graphics or text on the screen. Common types include capacitive, resistive, and infrared touchscreens.

[0003] The signal acquisition device is used to convert the touch position into an electrical signal. The core components include: a touch controller (processing the raw sensing signal, such as changes in capacitance and resistance), a sensor array (such as the ITO electrode array of a capacitive screen, which senses the touch position), a signal conditioning circuit (amplifying and filtering the raw signal), and an analog-to-digital converter (converting the analog signal into a digital signal), which finally outputs the touch coordinate data.

[0004] Fault diagnosis and testing equipment is used to detect abnormal touch screen functions. Main types and functions include: touch screen testers (testing touch response speed, linearity, resolution, and multi-touch accuracy); oscilloscopes (observing touch signal waveforms to identify signal interference, attenuation, and other problems); multimeters (measuring circuit resistance and voltage to troubleshoot open circuits and short circuits); dedicated diagnostic software (analyzing touch data to identify drift, dead zones, and accidental touches); and stress testing equipment (simulating different touch pressures to test response stability).

[0005] Currently, in production line testing stations, the oscilloscopes for touchscreen signal acquisition and fault diagnosis testing equipment are fixed to the production line brackets, resulting in low replacement efficiency. Fixed installation requires specialized tools for disassembly, making it difficult for non-professionals to operate quickly, thus extending equipment replacement time; the risk of production interruption is high, as oscilloscope failure and subsequent testing shutdowns directly lead to production line stoppages, reducing production efficiency and increasing time costs; maintenance costs increase, frequent downtime can easily cause order delays, requiring additional manpower and time for handling, and may even affect product delivery; the equipment lacks flexibility, as fixed installation restricts the flexible deployment of oscilloscopes, preventing temporary adjustments to their position or equipment according to testing needs, resulting in poor adaptability; there are potential quality risks, as the inability to promptly replace equipment during downtime may lead to the failure to detect problematic products in a timely manner, increasing potential quality risks. Summary of the Invention

[0006] The main objective of this invention is to provide a touch screen signal acquisition and fault diagnosis testing device, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A touch screen signal acquisition and fault diagnosis testing device includes an oscilloscope detector, a display screen, operation buttons, an interface, and test lines. The display screen, operation buttons, and interface are all installed at the front end of the oscilloscope detector. The external end of the interface is connected to a test line, which is connected to the touch screen connector for testing by the oscilloscope. The back of the oscilloscope detector is connected to a position adjustment device, and the other end of the position adjustment device is connected to a vertical mounting bracket, which enables the installation and wiring of the oscilloscope.

The hinge and the fixing seat are connected to both ends of the adjusting arm by a rotating shaft and a retaining ring. The fixing seat and the docking straight plate are welded and fixed. Multiple docking holes are equidistantly distributed on the docking straight plate.

[0009] In a further alternative, the top of the support column is provided with a sealing top cover, and the lower edge of the sealing top cover is provided with a slide rail. The side wall of the slide rail is provided with a track groove, and multiple magnetic columns are provided in the track groove. The side wall of the magnetic column is provided with a hole. The wire inserted at the wiring hole is placed at the edge of the magnetic column, and a cable tie is inserted into the hole to fix it to the magnetic column.

[0010] In a further alternative, the outer end of the magnetic column is provided with a restrictive cable routing ring, and the end face of the restrictive cable routing ring is provided with a through hole.

Detailed Implementation

[0016] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0017] like Figures 1-6 As shown, a professional testing device for touchscreen signal acquisition and fault diagnosis comprises a core functional module consisting of an oscilloscope detector 4, a display screen 5, operation buttons 6, an interface 7, and a test cable 8. The display screen 5, operation buttons 6, and interface 7 are all highly integrated and arranged on the front operation panel of the oscilloscope detector 4. This layout optimizes the human-machine interface, facilitating direct operation control and real-time observation of the test status during testing. A dedicated test cable 8 is securely connected to the external end of the interface 7, enabling reliable connection to the corresponding connector of the touchscreen under test. This allows the oscilloscope detector 4 to perform high-precision real-time acquisition, dynamic monitoring, and detailed waveform analysis of the electrical signals output by the touchscreen.

[0018] On the back of the oscilloscope detector 4, a position adjustment device 3 is connected, the other end of which is connected to a vertical mounting bracket 1. The vertical mounting bracket 1 allows for flexible installation and orderly cable routing of the entire test equipment, fundamentally ensuring excellent structural stability and wide environmental adaptability in diverse testing environments. The vertical mounting bracket 1 also features a specially designed add-on mounting accessory. With this accessory, users can achieve auxiliary reinforcement of the oscilloscope or obtain a second alternative installation method, thus flexibly addressing different on-site installation conditions, space constraints, or special testing requirements.

[0019] Specifically, the vertical mounting bracket 1 consists of a support column 11, a bottom mounting plate 12, and multiple cable routing holes 13. The bottom mounting plate 12 is located at the bottom end of the support column 11, and its primary function is to provide a stable and secure base for the entire mounting bracket. Multiple dedicated cable routing holes 13 are evenly distributed on the side wall of the support column 11. These holes are designed to facilitate the routing, arrangement, and centralized management of various cables, thereby maintaining a clean and safe work environment. The top end of the bottom mounting plate 12 is also machined with standard round holes, which can be used for direct mounting of equipment or for docking with other components.

[0020] To achieve height adjustment and a secure connection, the upper center of the bottom mounting plate 12 is equipped with a threaded tube with external threads. This threaded tube can be precisely inserted into the corresponding opening at the lower end of the support column 11. By rotating the bottom mounting plate 12, the threaded connection between the two can be achieved, and a certain range of height fine-tuning can be performed. The cable routing hole 13 is designed as an elliptical hole. This shape can accommodate cables of different diameters and sizes, enhancing versatility. In addition, each cable routing hole 13 has a wear-resistant rubber ring fitted around its edge. This rubber ring effectively prevents the cable from being worn by the sharp edge of the hole during passage, while also enhancing the sealing of the hole and providing a certain degree of dust prevention.

[0021] The add-on mounting components mainly include add-on clamps 2, add-on discs 9, and add-on holes 10. Add-on clamps 2 can be flexibly fitted onto the support column 11 at any suitable height and locked in place through adjustment. Add-on discs 9 are fixed to the side wall of add-on clamps 2. Multiple add-on holes 10 are provided on the end face of the add-on disc 9. The diameter of these add-on holes 10 is consistent with the diameter of the standard circular holes on the end face of the bottom mounting disc 12, thus ensuring compatibility and interchangeability between various mounting accessories and facilitating modular expansion by users.

[0022] The position adjustment device 3 is a key component for adjusting the detection angle. It consists of a fastening clamp 31, an adjusting arm 32, a hinge 33, a fixing base 35, a docking straight plate 36, and multiple docking holes 37. The fastening clamp 31 is fitted onto the support column 11. The side wall of the fastening clamp 31 is flexibly connected to one end of the adjusting arm 32 via a hinge 33. The other end of the adjusting arm 32 is connected to a docking straight plate 36 via the fixing base 35. Multiple docking holes 37 are evenly spaced on the end face of the docking straight plate 36. These holes are used to dock with the corresponding interface on the back of the oscilloscope detector 4 and securely fix it, thereby mounting the detector on the adjustment device.

[0023] Both the fastening clamp 31 and the aforementioned additional clamp 2 are locked with bolts, thus being adjustablely fixed to the support column 11. To enhance the stability of the clamping and prevent slippage, anti-slip rubber rings are attached to the inner walls of both clamps. The hinge 33 and the fixing base 35 are connected to both ends of the adjusting arm 32 through the cooperation of a rotating shaft and a retaining ring. This structure allows the adjusting arm to rotate freely at multiple angles and lock in the required position. The fixing base 35 is fixed to the mating straight plate 36 by welding, ensuring the structural strength and reliability of the connection. The equidistant distribution of multiple mating holes 37 provides a variety of possible installation point options for the oscilloscope detector 4, enabling it to adapt to different detection positions, observation angles, and operating distance requirements.

[0024] A sealing cap 14 is installed on the top of the supporting column 11 for dust prevention and protection. A slide rail 15 is provided on the inner side of the lower edge of the sealing cap 14, and a track groove 16 is formed on the side wall of the slide rail 15. Multiple magnetic posts 17 are installed inside the track groove 16, and small holes are formed on the side walls of the magnetic posts 17. Cables passing through the cable routing holes 13 can be placed next to the magnetic posts 17, and then cable ties can be used to pass through the small holes in the side walls of the magnetic posts to secure the cables to the posts. In addition, a restrictive cable routing ring 18 is provided at the outer end of the magnetic posts 17, and a through hole 19 is formed on the end face of the restrictive cable routing ring 18. Cables can also pass through this through hole 19 and be secured to the cable routing ring with cable ties, thus achieving secondary cable fixation and organization. The cross-section of the track groove 16 is designed in an "O" shape, with its opening tapering inwards. This structure effectively prevents the magnetic posts 17 from accidentally falling out of the track groove.

[0025] The installation and usage process of the equipment is as follows: First, precisely insert the threaded tube at the upper end of the bottom mounting plate 12 into the corresponding opening at the lower end of the support column 11. Tighten the plate by rotating it using the threaded connection, and adjust the overall height. Next, place the fastening clamp 31 on the support column 11 at a suitable height and tighten the bolts to secure it (the anti-slip rubber ring on its inner wall enhances the clamping force and prevents slippage). Then, connect one end of the adjusting arm 32 to the fastening clamp 31 via the hinge 33, and the other end to the docking plate 36 via the fixing seat 35 (which is welded to the docking plate 36 as a whole). Afterward, align the back of the oscilloscope detector 4 with the docking plate 36 and dock and secure it through the docking hole 37 on the end face of the docking plate 36. Finally, firmly connect one end of the detection line 8 to the interface 7 on the front panel of the oscilloscope detector 4. If auxiliary installation is required, the additional clamp 2 can be fitted onto the support column 11 and fixed with bolts. The additional plate 9 is fixed to the side wall of the clamp. Other auxiliary accessories can be installed using the additional hole 10 on the end face of the additional plate 9 (whose diameter is consistent with the round hole of the bottom mounting plate).

[0026] When fixing the equipment, secure the entire vertical mounting bracket 1 to the test bench or working environment through the standard round holes on the end face of the bottom mounting plate 12. The spatial position and observation angle of the oscilloscope detector 4 can be flexibly adjusted by operating the hinge 33 and the adjusting arm 32 (whose pivot and retaining ring structure allows for multi-angle rotation and positioning). After adjustment, tighten the bolts of the fastening clamp 31 to lock the position. Reliably connect the other end of the test line 8 to the signal connector of the touchscreen under test. Finally, operate the operation button 6 on the front panel of the oscilloscope detector 4 to start the equipment. By observing the real-time signal waveform and data analysis results displayed on the screen 5, the signal acquisition and fault diagnosis tasks of the touchscreen can be completed.

[0027] In production line applications, first assemble the vertical mounting bracket 1 (adjusting the height of the bottom mounting plate 12 and the support column 11 via threaded connection), and fix it to the designated workstation on the production line using the standard round holes of the bottom mounting plate 12. Secure the fastening clamp 31 onto the support column 11; connect the adjusting arm 32 to the fastening clamp 31 via the hinge 33, and connect the other end to the docking plate 36 via the fixing seat 35. The oscilloscope detector 4 is fixed to the docking plate via the docking socket 37. Connect the device interface 7 to the touchscreen connector on the production line using the detection cable 8; all related cables are routed through the elliptical cable routing holes 13 (with wear-resistant rubber rings protecting the hole openings) on the side wall of the support column 11, achieving neat and orderly cable management. The operator presses the operation button 6 to start the equipment and observes the signal waveform on the display screen 5, enabling efficient online signal acquisition and fault diagnosis.

[0028] In system replacement or upgrade scenarios, the add-on clamp 2 can be fitted onto the existing support column 11 or the original system's mounting rod, and the bolts tightened for fixation (its inner anti-slip rubber ring effectively prevents slippage). The add-on plate 9 is fixed to the side wall of the add-on clamp 2 through the add-on holes 10, serving as a new auxiliary installation base. Subsequently, the fastening clamp 31 is fitted onto the add-on plate 9 or other positions on the support column 11 and fixed. The adjusting arm 32 is connected to the fastening clamp 31 through the hinge 33, and the other end is connected to the docking plate 36 through the fixing seat 35. The oscilloscope detector 4 is fixed through the docking plate 36. The test line 8 is connected to the touch screen connector, and the cable is managed through the wiring hole 13. The device is started by pressing the operation button 6, and the waveform is observed through the display screen 5. This device can then replace the original damaged system and continue to complete the testing task.
