[0076] 4. Adaptability and reliability: The structural design of the locking device has been carefully optimized to give it good adaptability and stability. Regardless of the working environment, the device can maintain an efficient working state to ensure the safety and stability of the assembly rack and wall panels.

[0077] Therefore, as a key component of the invention, the locking device not only simplifies the operating steps of the wall panel assembly process, but also significantly improves the position stability and safety of the wall panels during the assembly process.

[0078] In addition, in order to ensure the accuracy of the positioning of the auxiliary device, a monitoring unit is provided, which includes: a pressure sensor installed at the position where the spiral cam 102 contacts the limiting roller 302 to detect the load between the spiral cam 102 and the limiting roller 302;

[0079] A rotation speed sensor 1, mounted on the shaft of the synchronous motor 104, for real-time monitoring of the rotation speed of the spiral cam 102;

[0080] A second speed sensor, mounted on the rotating shaft of the spiral cam 102, for ensuring matching of the speed of the synchronous motor 104;

[0081] An angle sensor, mounted on the shaft of the spiral cam 102, to monitor the rotation angle of the spiral cam 102;

[0082] A temperature sensor is mounted on the surface of the spiral cam 102 to monitor the temperature of the spiral cam 102 and its related components;

[0083] An alarm, wherein the alarm is arranged on the bracket 1;

[0084] The controller 5 is electrically connected to the pressure sensor, the speed sensor 1, the speed sensor 2, the angle sensor and the alarm respectively. The controller 5 controls the alarm to work based on the pressure sensor, the speed sensor 1, the speed sensor 2 and the angle sensor, including:

[0085] Step 1: The controller calculates the working state index of the spiral cam 102 based on the pressure sensor, the speed sensor 1, the speed sensor 2, the angle sensor and formula (1):

[0086]

[0087] Wherein, X is the working state index of the spiral cam 102, F1 is the detection value of the pressure sensor, F2 is the designed maximum load capacity of the spiral cam 102, T1 is the detection value of the temperature sensor, T2 is the maximum working temperature of the spiral cam 102, Δ T is the sensitivity factor of the temperature change of the material of the spiral cam 102, θ1 is the detection value of the angle sensor, θ2 is the maximum rotation angle allowed by the spiral cam 102, α is the influence index of the material strength of the spiral cam 102, K is the influence index of the sensor accuracy, and μ is the friction coefficient between the spiral cam 102 and the limiting roller 302;

[0088] Step 2: The controller 5 compares the working state index of the spiral cam 102 with a preset working state index. If the working state index of the spiral cam 102 is less than the preset working state index, the alarm sounds an alarm.

[0089] Specifically, the goal of the formula is to monitor the working state of the spiral cam 102 in real time through data collected by multiple sensors, and trigger an alarm when the working state does not meet the requirements. It combines multiple factors such as pressure, speed, angle, temperature, friction coefficient, etc. to dynamically evaluate the performance of the spiral cam. The following is a part-by-part explanation of each part of the formula and how they combine with the data discussed previously.

[0090] 1. Temperature related items:

[0091]

[0092] T1: Current temperature (value detected by temperature sensor), reflecting the actual working temperature of the spiral cam and its related components.

[0093] T2: The maximum operating temperature of the spiral cam (the set design value), which is the upper limit of the temperature at which the spiral cam can operate normally.

[0094] Δ T : Temperature change sensitivity factor (may be adjusted based on factors such as material properties), representing the material's response to temperature changes.

[0095] Among them, this item expresses the impact of temperature differences on the working state of the spiral cam. Temperature changes will cause the material to expand or contract, thus affecting accuracy and durability. When the actual temperature approaches or exceeds the maximum operating temperature, the working state index X will drop significantly, indicating that the performance of the spiral cam is impaired.

[0096] 2. Friction coefficient and sensor accuracy:

[0097]

[0098] μ1: Friction coefficient (calculated from the contact force between the pressure sensor and the limit roller). The magnitude of the friction force directly affects the accuracy and life of the spiral cam.

[0099] K: Sensor accuracy impact index, used to reflect the impact of sensor error or system measurement accuracy on the working state.

[0100] α: Material strength influence index, used to adjust the influence of material strength on the life and accuracy of the spiral cam.

[0101] Among them, friction will affect the movement accuracy of the spiral cam. High friction will cause more wear and temperature rise, which will reduce the accuracy and life of the spiral cam. At the same time, the impact of sensor accuracy on data acquisition is also taken into account. If the sensor accuracy is low, it may lead to error accumulation, thus affecting the judgment of the working status.

[0102] 3. Load and angle related items:

[0103]

[0104] F1: The actual load (pressure applied to the spiral cam) detected by the pressure sensor directly affects the working state of the spiral cam. If the load is too large, it may cause the spiral cam to deform or wear prematurely.

[0105] F2: The maximum load capacity of the spiral cam design, which is the maximum load that the spiral cam can withstand without failure.

[0106] θ1: The current angle measured by the angle sensor, indicating the actual rotation angle of the spiral cam.

[0107] θ2: The maximum rotation angle allowed by the spiral cam. Exceeding this angle may cause excessive load or jamming of the device.

[0108] Among them, this item is used to calculate the combined effect of load and rotation angle. The relationship between load and angle is considered through sine and cosine functions. If the load is too high or the rotation angle exceeds the allowable range, the working condition index X of the spiral cam will drop significantly.

[0109] In summary, by combining multiple factors such as temperature, load, friction, angle, etc., a working state index X is dynamically calculated to evaluate the current working state of the spiral cam.

[0110] The influence of various factors is compound, which means that the deterioration of one factor (such as excessive temperature, excessive load, etc.) will lead to a significant decrease in the working state index. Therefore, the controller will calculate the current working state index X and compare it with the preset normal working state index. If X is less than the preset value, it means that the working state of the spiral cam no longer meets the requirements (there may be problems such as excessive load, excessive temperature, angle deviation, etc.), and the alarm will be activated to remind the operator to take measures.

[0111] Various sensors (pressure sensor, temperature sensor, angle sensor, speed sensor) collect real-time data and feed it back to the controller. The controller calculates the working status index based on formula 1 and determines whether an alarm is needed based on the set threshold.

[0112] In this way, the system can monitor the working status of the spiral cam in real time and provide necessary alarm signals to avoid accuracy degradation or damage due to improper operation or equipment failure.

[0113] The formula uses a variety of sensor data and a complex mathematical model (including factors such as temperature, load, friction, angle, etc.) to dynamically evaluate the working status of the spiral cam. The core idea is to evaluate the performance of the spiral cam based on real-time data monitoring and preset thresholds to ensure that it operates in the best condition and avoid damage or loss of accuracy caused by overload, high temperature, excessive angle, etc.

[0114] Working principle: When the auxiliary device is in use, the wall panel 4 to be assembled is placed inside the assembly rack 3, and the wall panel 4 to be assembled is clamped by the assembly rack 3 by adjusting the limit plate 305 and the sliding plate 101. According to the actual size and width of the wall panel 4 to be assembled, the sliding plate 101 and the limit plate 305 are adjusted at the same time to adapt to different types of wall panels 4 to be assembled. Then the assembly rack 3 and the limit plate 305 are fixed, and the sliding plate 101 and the bracket 1 are fixed at the same time to keep the position stable, so that the assembly rack 3 and the bracket 1 have a wide adaptability and improve the working effect. After fixing, the bracket 1 and the upper end of the wall panel 4 to be assembled are pushed to move by the universal wheel 103 , so that the wall panel 4 to be assembled is close to the installation position, and subsequent operations are carried out. The spiral cam 102 is driven to rotate by the synchronous motor 104, and the limiting roller 302 and the transmission arm 301 are driven to move. The transmission arm 301 and the assembly frame 3 are limited by the auxiliary T-shaped sleeve 2. The auxiliary T-shaped sleeve 2 is limited by the positioning tube 202 and is stepped up at a uniform speed. While approaching the assembly position, the position of the wall panel 4 to be assembled is kept stable, and the structural position is stable. Stable feeding work can be achieved through the synchronous motor 104, and the transmission work is carried out through the limiting roller 302. In the step-by-step moving and conveying work, the spiral cam 102 is rotated, and the limiting roller 302 is used to drive the limiting roller 302. The roller 302 is limited by gravity and the guide track to keep a stable position. The outermost spiral cam 102 transports the transmission arm 301 and the limiting roller 302 to the highest position, while the innermost spiral cam 102 transports the transmission arm 301 and the limiting roller 302 to the lowest position, which is convenient for loading. While loading and assisting through the assembly frame 3, preliminary detection work is carried out through the balance detection plate 304 at the rear end of the assembly frame 3. The pillow block weighing sensors at the upper and lower ends can detect the position of the wall panel 4 to be assembled, thereby detecting the balance between the wall panel 4 to be assembled and the assembly frame 3, and then detecting the balance between the pressure measuring plate 303 and the auxiliary wheel 3032. The force sensor monitors the pressure on both sides of the auxiliary wheel 3032, so as to judge the position between the assembly frame 3 and the wall panel 4 to be assembled, and then monitors the distance between the two sides of the assembly frame 3 and the installation position through the laser ranging probe 306, so as to monitor the assembly frame 3, improve the detection effect, and improve the detection accuracy, so that the judgment effect of the controller 5 is better, and the electric cylinder 3031 is extended and retracted. When different electric cylinders 3031 are extended, the position of the auxiliary wheel 3032 at different positions is adjusted, so as to adjust the position between the bottom end of the wall panel 4 to be assembled and the assembly frame 3, perform anti-falling operation, improve position stability, and facilitate the external wall assembly work.
