Description

Technical Field

[0001] The invention belongs to the technical field of electronic manufacturing equipment and relates to an LCM automatic retrieval matching and full code burning firmware system. Background Art

[0002] In the mass production of LCD modules, firmware programming is a critical step in ensuring proper functionality. The core challenge lies in efficiently and reliably programming firmware for LCD modules of varying models and physical interface characteristics. Production lines often handle modules of varying sizes, each with varying electrical contact points in shape, position, and layout. This requires highly flexible and compatible programming tools to ensure absolutely stable connections, preventing data transmission interruptions or firmware corruption caused by poor connections, which can directly impact production efficiency and product yield.

[0003] The common practice in the industry is to design dedicated programming tools for each type or category of LCD modules. Operators must manually select and replace the appropriate tooling fixture based on the module model being programmed. After the module is placed, it is typically contacted using a simple array of spring probes, and the programming process is executed from a single data source. If an error occurs during the programming process, the module is typically marked as defective and removed from the production line for manual investigation or simply scrapped. This entire process has a low degree of automation and lacks effective fault tolerance and recovery mechanisms.

[0004] To address the above issues, the traditional single-data source burning model lacks robustness. Any momentary disconnection or power fluctuation may cause incomplete firmware writing, resulting in permanent damage to the module, increasing production costs and material waste. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides an LCM automatic retrieval and matching and full code burning firmware system.

[0006] An LCM automatic search and matching and full code burning firmware system, comprising: The physical identification module places the LCM module on the tooling table, aligns the metal contact piece group with the tooling probe array, activates the gravity sensor switch to detect the placement of the LCM module, and outputs the contact piece position signal; Adaptive matching module: Based on the contact piece position signal, the memory alloy probe moves toward the center of the metal contact piece. When the shape matches, the probe adaptively bends and snaps into the edge of the metal contact piece, generating a circuit path and outputting a physical matching success signal. The locking module is pressed and locked. Based on the physical matching success signal, it drives the cylinder piston to press down and lock the LCM module. When the cylinder pressure reaches the preset threshold, it outputs the burning start command. Synchronous burning module, based on the burning start instruction, the main storage block writes the firmware data to the LCM module through the probe circuit, the backup storage block copies the main storage block data stream in real time, and outputs the burning process status stream; The process detection module, based on the programming process status flow, sends a pulse signal from the main storage block to the current sensor. If the pulse amplitude decays beyond a preset threshold, it triggers a mechanical switch to switch the programming source to the backup storage block and outputs a programming completion signal or a programming abnormality signal. The abnormal recovery module, based on the abnormal burning signal, lights up the red warning light and interrupts the pneumatic locking; the operator presses the physical reset button to trigger the backup storage block to directly overwrite the LCM storage area; and outputs the recovery completion signal; Reset the exit module. Based on the burning completion signal or the rescue completion signal, the cylinder reset spring is activated to eject the LCM module to the discharge slide. The tooling probe automatically restores to its initial straight state and outputs the tooling reset ready signal.

[0007] A further solution of the present invention is to output a contact piece position signal, comprising the following steps: Place the LCM module in the preset loading area of ​​the tooling table and adjust the position so that the center point of the metal contact piece group coincides with the center line of the tooling probe array; The gravity sensor switch senses that the weight of the LCM module exceeds the preset weight threshold and activates the memory alloy probe recognition function; The memory alloy probe measures the relative position deviation with the metal contact piece group, generates and outputs the contact piece position signal including the space coordinate parameters.

[0008] A further solution of the present invention outputs a physical matching success signal, comprising the following steps: Based on the contact piece position signal including spatial coordinate parameters, the control unit outputs a driving instruction to move the memory alloy probe to the center point of the metal contact piece; After the probe contacts the metal contact piece, only when the geometric shapes are completely matched, the probe is pressed and adaptively bent to form a complementary groove structure that is stuck into the edge of the metal contact piece; When the probe is fully inserted, the electrical impedance drops below the preset impedance threshold, and a physical matching success signal is generated and output.

[0009] A further solution of the present invention is to output a burn start instruction, comprising the following steps: The physical matching success signal triggers the cylinder system to drive the cylinder piston downward to fix the LCM module on the probe station; During the downward pressing process of the cylinder piston, the pressure sensor detects that the pressure value reaches the preset pressure threshold and generates and outputs a probe circuit stability signal; Based on the stable signal of the probe circuit, the burn start command is output.

[0010] A further solution of the present invention is to output the burning process status stream, comprising the following steps: The burn start command activates the main storage block and writes firmware data to the LCM module in serial communication through the probe circuit; The backup storage block physically mirrors the primary storage block data stream through a hardware data splitter, achieving zero-delay synchronous replication; Monitor the writing progress of the main storage block and the data matching degree of the backup storage block in real time, integrate and output the burning process status stream including writing progress parameters and backup integrity parameters.

[0011] A further solution of the present invention is to output a burning completion signal or a burning abnormality signal, comprising the following steps: Based on the programming process status flow indicating that programming is in progress, the main storage block generates a fixed amplitude pulse signal every second and sends it to the current sensor; The current sensor detects the pulse amplitude. If the amplitude decay exceeds a preset decay threshold, it triggers a mechanical switch to disconnect the main storage block and close the backup storage block connection. If the writing progress reaches the completion value and there is no amplitude attenuation, the burn completion signal is output; if amplitude attenuation occurs or the program is completed after switching, the burn abnormality signal is output.

[0012] A further solution of the present invention is to output a rescue completion signal, comprising the following steps: The abnormal burning signal drives the red warning light to light up and sends a release command to the cylinder system to interrupt the pneumatic locking; When the physical reset button is pressed, an electrical signal is generated to trigger the backup storage block to directly overwrite the LCM storage area through the probe circuit; After the direct write overwrite is completed, the physical progress indicator bar pops up to the preset identification position and outputs the rescue completion signal.

[0013] A further solution of the present invention is to output a tool reset ready signal, comprising the following steps: The burning completion signal or the rescue completion signal triggers the cylinder reset spring to release the mechanical potential energy, ejecting the LCM module to the discharge slide; After the LCM module is ejected, the memory alloy probe automatically returns to its original straight state based on the phase change characteristics of the material; The displacement sensor detects that the probe position deviation is maintained below the preset deviation threshold and outputs a tooling reset ready signal.

[0014] In summary, the present invention has the following beneficial technical effects: 1. By introducing an adaptively deformable shape-memory alloy probe, automatic recognition and locking of different physical contact point shapes is achieved. This design enables a single fixture to be compatible with multiple LCD module models, eliminating the need for specialized fixtures for different modules, greatly improving the flexibility and versatility of the production line. This not only significantly reduces downtime caused by line changes, but also lowers equipment hardware investment and maintenance costs, and avoids production accidents caused by manually selecting the wrong fixture.

[0015] 2. A multi-layered, stable physical connection mechanism has been established, significantly enhancing the reliability of the programming process. The probe's adaptive deformation creates a mechanical engagement with the contact pad, forming a stable initial connection. The pneumatic system then activates to apply uniform pressure to the module, further securing it securely to the probe station. This combination of deformation locking and pneumatic compression ensures continuous, stable, and low-impedance electrical contact between the probe and the contact pad, fundamentally eliminating programming failures caused by vibration, displacement, or inadequate contact.

[0016] 3. A fault-tolerant architecture with dual-path synchronous programming and real-time switching ensures firmware data integrity and programming continuity. While programming is occurring on the primary storage block, the backup storage block performs physical, real-time data mirroring. Current pulse signals continuously monitor the health of the primary data link. If an anomaly, such as signal attenuation, is detected, the system automatically switches the programming source to the backup storage block within milliseconds, seamlessly continuing the programming process.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The following is combined with Figure 1-Figure 2 The preferred embodiments of the present invention are described in detail.

[0022] Refer to the attached Figure 1-Figure 2 The present invention proposes an LCM automatic retrieval matching and full code burning firmware system, which includes the following modules: The physical identification module places the LCM module on the tooling table, aligns the metal contact piece group with the tooling probe array, activates the gravity sensor switch to detect the placement of the LCM module, and outputs the contact piece position signal; Adaptive matching module: Based on the contact piece position signal, the memory alloy probe moves toward the center of the metal contact piece. When the shape matches, the probe adaptively bends and snaps into the edge of the metal contact piece, generating a circuit path and outputting a physical matching success signal. The locking module is pressed and locked. Based on the physical matching success signal, it drives the cylinder piston to press down and lock the LCM module. When the cylinder pressure reaches the preset threshold, it outputs the burning start command. Synchronous burning module, based on the burning start instruction, the main storage block writes the firmware data to the LCM module through the probe circuit, the backup storage block copies the main storage block data stream in real time, and outputs the burning process status stream; The process detection module, based on the programming process status flow, sends a pulse signal from the main storage block to the current sensor. If the pulse amplitude decays beyond a preset threshold, it triggers a mechanical switch to switch the programming source to the backup storage block and outputs a programming completion signal or a programming abnormality signal. The abnormal recovery module, based on the abnormal burning signal, lights up the red warning light and interrupts the pneumatic locking; the operator presses the physical reset button to trigger the backup storage block to directly overwrite the LCM storage area; and outputs the recovery completion signal; Reset the exit module. Based on the burning completion signal or the rescue completion signal, the cylinder reset spring is activated to eject the LCM module to the discharge slide. The tooling probe automatically restores to its initial straight state and outputs the tooling reset ready signal.

[0023] In one embodiment of the present invention, outputting a contact piece position signal includes the following steps: Place the LCM module to be programmed on the tooling table so that the triangular, square or circle metal contact pieces next to the cable are aligned with the tooling probe array.

[0024] Specifically, take the LCD module to be burned, that is, the LCM module, and prepare to perform the firmware burning operation. Place the LCD module in the preset bearing area on the surface of the workbench. Manually adjust the position and orientation of the LCD module to ensure that the triangular, square, or circular metal contact piece group set next to the cable on the LCD module maintains a vertical alignment with the tips of each probe of the tooling probe array fixed on the workbench, that is, the center point of the metal contact piece group coincides with the center line of the probe array. The alignment operation ensures that the subsequent electrical connection process does not deviate or misalign. The LCD module is an electronic component used for display. The triangular, square, or circular metal contact piece group next to the cable is three geometrically shaped metal contacts attached to the edge of the LCD module cable. Each contact serves as a conductive connection point. The workbench is a dedicated work platform for fixing the LCD module. The tooling probe array is a regularly arranged structure composed of multiple conductive probes used to establish an electrical channel with the metal contact piece.

[0025] After the gravity sensor switch at the bottom of the tooling detects the placement of the LCM, it activates the recognition function of the memory alloy probe matrix.

[0026] Specifically, after the LCD module is placed and its weight is applied to the workbench, a gravity sensor switch mounted on the bottom of the workbench senses a change in load exceeding its weight threshold—this threshold is based on factory-measured average weights of standard LCD modules, such as a 100-sample test. The gravity sensor switch triggers an electrical output signal, which is transmitted to the control unit to initiate the recognition function of the memory alloy probe matrix. The recognition function causes each probe in the memory alloy probe matrix to begin a position search operation. The memory alloy probe matrix is ​​an array of probes made of shape-memory material. Applying an electric current causes temperature changes, resulting in adaptive displacement to match the position of the contact piece.

[0027] The output contact piece position signal contains the contact piece space coordinate parameters.

[0028] Specifically, after the memory alloy probe matrix activates its recognition function, the displacement sensor on each memory alloy probe measures the relative position deviation between it and the corresponding metal contact piece. The 3D coordinate calculation unit processes this deviation data to generate a spatial coordinate parameter signal containing the center point of each metal contact piece. This signal records the X-axis horizontal coordinate value, Y-axis vertical coordinate value, and Z-axis depth coordinate value in digital format. The contact piece position signal, as an output result, provides the precise position information required for subsequent steps, ensuring that the probe can perform the next position movement operation.

[0029] For example, in the experiment, after placing a liquid crystal display module with a triangular contact piece on the workbench, the weight threshold is set to 50 grams. The gravity sensor switch correctly detects and triggers when the weight reaches 50 grams, and the memory alloy probe matrix recognition function is activated to output the contact piece position signal, such as the triangle vertex coordinates. Equal to 10.0mm, Equal to 15.0mm, Equal to 0.5mm.

[0030] In one embodiment of the present invention, outputting a physical matching success signal includes the following steps: The memory alloy probe moves toward the center of the triangular, square or circular metal contact piece according to the contact piece position signal.

[0031] Specifically, after receiving the contact piece position signal, which contains the three-dimensional spatial coordinate parameters of the center point of the triangular, square, or circular metal contact piece, such as the X-axis horizontal value, the Y-axis vertical value, and the Z-axis depth value, the control unit converts the coordinate parameters into drive instructions and outputs them to the memory alloy probe matrix. By applying a specific current to the probe body, the shape memory effect induces temperature changes, causing the probe tip to actively move to the coordinate specified position and finally align with the center point of the contact piece, ensuring that the position deviation is less than the deviation threshold, which is set based on the average error of the positioning test of 100 samples in the factory. The center point of the triangular, square, or circular metal contact piece is the pre-defined geometric center point position on the metal contact piece.

[0032] After the probe contacts the metal sheet, only when the shapes are completely matched will the probe bend adaptively due to pressure and snap into the edge of the contact sheet.

[0033] Specifically, after the probe tip contacts the surface of the metal sheet, the applied external pressure stimulates the reconstruction of the lattice structure of the memory alloy material. Only when the specific geometric shape of the metal contact sheet, such as triangle, square or circle, is completely consistent with the shape set by the probe, the probe tip adaptively bends and deforms due to pressure to produce a complementary groove structure. For example, a triangular contact sheet causes the probe to bend into a triangular groove, and finally it is stuck into the edge of the contact sheet to achieve a mechanical locking form; if the shape does not match, the probe remains in its original shape and cannot be stuck.

[0034] After the probes are fully aligned, a circuit path is generated and a physical matching success signal is output.

[0035] Specifically, when the probe is fully engaged with the edge of the contact piece, a seamless electrical connection is formed between the probe's conductive layer and the metal contact piece, establishing a circuit path. The electrical impedance drops below the ohmic threshold, which is determined by averaging ten impedance test calibration values ​​from standard industrial equipment. This triggers the state detection circuit to generate a physical match success signal as a high or low level indication. A circuit path is a continuous electrical path established between two conductors, and the physical match success signal is a digital signal indicating electrical connectivity.

[0036] In one embodiment of the present invention, outputting a burn start instruction includes the following steps: The physical matching success signal drives the cylinder piston on the side of the tooling to press down, locking the LCD display module to the probe station.

[0037] Specifically, the physical matching success signal of step S2 is used as the input signal, and the high and low level electrical connectivity status indication triggers the cylinder system installed on the side of the workbench. The cylinder system is powered by a compressed air source, driving the cylinder piston to move downward and apply mechanical pressure to the surface of the liquid crystal display module to fix it on the surface of the probe station, ensuring that there is no displacement or loosening between the probe array and the metal contact piece of the liquid crystal display module in subsequent operations.

[0038] The cylinder piston is the moving part of the pneumatic actuator, which is used to convert air pressure into linear mechanical displacement. The probe station is a platform structure on which the probe array is installed on the tooling table.

[0039] When the cylinder pressure reaches the pressure threshold, the pressure sensor generates a probe circuit stable signal.

[0040] Specifically, as the cylinder piston presses downward, a pressure sensor integrated within the cylinder continuously monitors the pressure applied by the piston. When the pressure reaches a preset threshold—set based on 20 factory burn-in test calibrations, such as multiple tests on ten standard LCD modules to ensure electrical contact stability—the pressure sensor generates a probe circuit stability signal as a high or low level status indicator. A pressure sensor converts physical pressure changes into an electrical signal output. The probe circuit stability signal confirms that the electrical connection is stable and free of fluctuations.

[0041] Output the burn start command.

[0042] Specifically, after receiving the probe circuit stability signal, the control unit directly outputs the signal as a burn start instruction. The burn start instruction is a digital status signal indicating that the pneumatic locking has been completed and the probe circuit is in a stable state, ready to enter the subsequent burn operation. The burn start instruction is a control signal to start the firmware writing process.

[0043] For example, when a high-level physical matching success signal is output, the cylinder piston is driven down to the liquid crystal display module locking position and the pressure reaches the 500 kPa pressure threshold, and then a high-level probe circuit stable signal is output, and finally a burning start instruction is generated.

[0044] In one embodiment of the present invention, outputting a burning process status stream includes the following steps: The main storage block writes firmware data to the liquid crystal display module through the probe circuit.

[0045] Specifically, after receiving the burn-initiate command in step S3, the high and low level status signals trigger the control unit to activate the data output mechanism of the main storage block. The main storage block is an embedded non-volatile storage device, such as a flash memory chip, installed inside the workbench. It stores the firmware program file code set to be burned. The firmware data is the binary program code used to control the operation of the liquid crystal display module. The process of writing to the liquid crystal display module through the probe circuit is performed via digital serial communication. The output port of the main storage block is directly connected to the storage interface of the liquid crystal display module via an electrical channel established by an array of memory alloy probes, namely the probe circuit. Each bit of data is transmitted through the probes and accurately written into the internal memory of the liquid crystal display module, completing the firmware burn operation. The entire write speed is set to 100 megabits per second, calibrated based on the average results of 30 sets of factory burn efficiency tests to ensure reliability.

[0046] The backup storage block replicates the data stream output by the primary storage block in real time to achieve physical-level synchronization.

[0047] Specifically, when the primary storage block transmits data to the LCD module, the backup storage block directly physically mirrors the primary storage block's output stream via a hardware data splitter. The backup storage block is a storage device with the same specifications as the primary storage block, such as a backup flash memory chip. Physical synchronization means data replication is completely electronically implemented, requiring no software intervention and ensuring zero latency. In practice, data lines are connected in parallel to the primary storage block output and the backup storage block input. The synchronization transmission delay is less than a time threshold, which is derived from the average delay set by 20 sets of hardware synchronization tests at the factory. The typical value of the time threshold is set to 0.01s.

[0048] Real-time replication requires that every bit of output data is received and stored immediately by the backup storage block. If a transmission interruption occurs, the backup automatically pauses the subsequent recovery sequence.

[0049] Output the burning process status stream including the main storage block writing progress and backup integrity parameters.

[0050] Specifically, during the programming process, the ratio of the currently written data volume divided by the total data volume is read from the primary storage block every second as a write progress parameter. The write progress parameter ranges from 0 to 100% and is calculated based on a counter for the total amount of data being programmed. A backup integrity parameter uses a checksum comparison mechanism to generate a percentage of the match between the backup storage block data and the primary storage block output stream. A percentage less than 100% indicates an anomaly. These parameters are integrated into a programming process status stream, output once per second in a 16-bit data frame format. The parameter setting frame rate is based on a programming time optimization goal, such as completing the program within ten seconds.

[0051] In one embodiment of the present invention, outputting a burning completion signal or a burning abnormality signal includes the following steps: The main storage block sends a pulse signal to the current sensor every second, and the pulse amplitude is constant under normal conditions.

[0052] Specifically, after receiving the output of the programming process status stream, which includes the main storage block write progress parameters and backup integrity parameters, a timer count mechanism is activated to output a control signal to the main storage block every second when the write progress is less than 100%, driving the main storage block to generate a fixed-amplitude pulse signal that is sent to the current sensor. The pulse signal is a periodic electrical square wave, such as a five-volt amplitude, calibrated based on the average amplitude of twenty sets of factory-tested, non-interference programming tests under normal conditions. After receiving the pulse signal, the current sensor measures its amplitude, maintaining a constant amplitude deviation of no more than 0.1 volt under lossless connection conditions. A current sensor is a hardware device, such as a Hall effect sensor element, that senses changes in electrical signal strength.

[0053] If the pulse amplitude decays by more than 10%, such as due to power failure or poor contact, the current sensor triggers a mechanical switch to switch the programming source to the backup storage block.

[0054] Specifically, for each received pulse signal, the current sensor detects the actual amplitude and compares it to a reference amplitude of five volts. If the detected amplitude is less than 4.5 volts, indicating an attenuation greater than a 10 percent threshold (calibrated based on fifteen factory-tested simulated power-off cycles), the current sensor generates an electronically controlled output that actuates a mechanical switching switch. The mechanical switching switch is a mechanical multi-way relay that physically switches circuit paths. Upon activation, its moving contacts disconnect the main storage block from the probe circuit and simultaneously close the backup storage block from the probe circuit, achieving a hot-swap operation. The switching delay is less than 0.05 seconds, a threshold determined by the average of ten factory-tested switching responses, ensuring seamless continuity of the programming process.

[0055] Outputs the burning completion signal successfully or the burning abnormal signal failed.

[0056] Specifically, during the programming process, if all pulse amplitudes do not decay by more than 10 percent, the programming progress in the programming process status stream reaches 100 percent, triggering the control unit to output a programming completion signal. For example, a high level of one volt indicates success. If amplitude decay triggers a switchover or the backup is complete and the programming progress reaches 100 percent, a mechanical switch interrupts the indication or status stream control, outputting a programming failure signal. For example, a low level of zero volts indicates failure. Both the programming completion signal and the programming failure signal are digital electrical signals that are directly used for system decision-making.

[0057] In one embodiment of the present invention, outputting a rescue completion signal includes the following steps: The abnormal burning signal lights up the red warning light on the workbench and interrupts the pneumatic locking.

[0058] Specifically, upon receiving the abnormal programming signal from step S5, such as a zero-volt low-level electrical status indication, the control unit immediately sends a command signal to the workbench integrated circuit. This command signal activates the red warning light element above the workbench to illuminate and provide a continuous warning. The red warning light is a 630-nanometer light-emitting diode array, optimized for visibility based on fifteen sets of factory ergonomic tests. A release command is then sent to the cylinder system, shutting off the compressed air supply and driving the cylinder piston to urgently reset the locking state, releasing the LCD module. Interrupting the pneumatic locking requires a piston retraction delay of less than 0.5 seconds, a time threshold determined by the average of ten factory emergency response experiments.

[0059] Pressing the physical reset button triggers the direct writing of the backup storage block data to overwrite the storage area of ​​the LCD module.

[0060] Specifically, after observing the red warning light illuminate, manually press the physical reset button on the workbench surface. Based on 20 factory press test calibrations, this button, a mechanical trigger switch, requires a downward stroke of at least 0.5 mm to ensure effective triggering. This press generates an electrical signal that triggers the control unit to activate the backup storage block's direct write overwrite mechanism. The backup storage block, through a probe circuit, writes its complete data image directly to the internal memory of the LCD module, overwriting the original storage area contents. This direct write overwrite process utilizes physical hardware channels to avoid processor transfer, achieving a write rate of 100 megabits per second, consistent with the primary storage block's programming rate. The overwrite operation takes ten seconds to complete, based on the storage area's capacity of 100 megabits divided by the write rate.

[0061] When the overwriting is completed, a physical progress indicator pops up to indicate that the rescue is successful and a rescue completion signal is output.

[0062] Specifically, after the direct-write overwrite is complete, the control unit receives a confirmation signal from the backup storage block that the overwrite is complete, and activates a mechanical device, a physical progress indicator bar, mounted on the side of the workbench. The bar is a metal ruler with a spring-loaded return mechanism, and its 10-centimeter pop-up length serves as a visual indicator of successful recovery. This position is calibrated based on 25 factory-tested manual identification tests. Simultaneously, the control unit outputs a recovery completion signal, such as a 5-volt high-level digital signal, indicating the end of the abnormal recovery operation. This recovery completion signal serves as an electrical status instruction that triggers subsequent processes.

[0063] In one embodiment of the present invention, outputting a tool reset ready signal includes the following steps: The burning completion signal or the rescue completion signal activates the cylinder reset spring to eject the LCD module to the discharge chute.

[0064] Specifically, upon receiving a high-level burn-complete signal or a high-level rescue-complete signal, the control unit sends a reset command to the cylinder system, triggering the release of mechanical potential energy from the pre-compressed reset spring within the cylinder. This spring is an alloy steel spiral with a yield strength of 1,000 megapascals, calibrated based on fifteen factory elasticity tests. The spring force drives the cylinder piston upward at a speed of 0.5 meters per second, propelling the LCD module off the probe station surface and onto an inclined discharge chute. The discharge chute is a metal guide rail with a 35-degree inclination, which uses gravity to guide the LCD module toward the collection area. The 20-centimeter ejection distance has been verified as lossless by ten collision tests.

[0065] The tooling probe automatically returns to its original straight state due to the release of pressure.

[0066] Specifically, after the LCD module bounces off the probe station, the shape memory alloy probe array loses its external pressure load and naturally cools to room temperature due to the material's phase transition properties. The probes automatically return to their initial straight state in less than 0.3 seconds, a time threshold determined by the average data from 20 shape recovery experiments conducted at the factory. The initial straight state is defined as a linear alignment deviation of the probe tips of less than 0.05 mm, as verified by laser alignment. This recovery process is independent of external energy and is achieved solely through the reorganization of the alloy lattice.

[0067] Output the tooling reset ready signal and wait for the next LCD display module to be placed.

[0068] Specifically, after the probe array returns to its initial straight position, the displacement sensor detects that the displacement deviation remains within 0.05 mm for 0.5 seconds, triggering the control unit to generate a three-volt high-level tooling reset ready signal. This signal drives the tooling table system into a standby state, and the gravity sensor reset sensitivity increases to the detection threshold. The output signal is transmitted to the system's main control interface via an isolated optocoupler, clearly indicating that the device is ready to accept the next LCD module.

[0069] For example, following the five-volt high-level rescue completion signal output from step S6, the process proceeds to step S7. The cylinder's return spring releases energy, causing the piston to move upward by 20 centimeters within 0.2 seconds, ejecting the LCD module. The shape memory alloy probe recovers its straightness within 0.28 seconds, with a displacement deviation of 0.03 millimeters. Finally, a three-volt tool reset ready signal is output. This data, derived from 30 factory reset test operations, verifies the validity of the threshold settings of 0.5 meters per second for the spring release speed and 0.3 seconds for the probe recovery time.

[0070] It should be noted that the formulas described above, through the principle of dimensional consistency and mathematical standardization (e.g., normalization, dimensionless parameter conversion, or unified unit system), can translate physical quantities of different attributes into unitless standard values ​​or homogeneous, superimposable parameters. This eliminates the interference of different dimensions on operational logic, ensuring that the formulas retain the distribution characteristics of the original data while maintaining mathematical rationality and adaptability to objective laws. These are merely exemplary embodiments of the present invention and are not intended to limit the scope of the invention.

[0071] The modules can be implemented in whole or in part through software, hardware, or a combination thereof, supporting hardware embedded in or independent of a processor in a computer device, and also supporting software stored in a memory in a computer device, so that the processor can call and execute operations corresponding to the modules.

[0072] It should be noted that the human body information (including but not limited to human device information and personal information, etc.) and data (including but not limited to data used for analysis, stored data and displayed data, etc.) involved in the present invention are all information and data authorized by the human body or fully authorized by all parties.
