Description

Technical Field

[0002] The present invention relates to the technical field of building tools, and in particular to an ALC wall panel installation device and an operating method. Background Art

[0004] Foam concrete, also known as foamed cement, lightweight concrete, and ALC wallboard, is an environmentally friendly, energy-saving, and cost-effective new building material. It boasts low density, lightweight construction, and excellent thermal insulation, sound insulation, and earthquake resistance. Foam concrete is created by chemically or physically introducing air or gases such as nitrogen, carbon dioxide, and oxygen into the concrete slurry. After curing and forming, the concrete slurry contains a large number of tiny, closed pores. As a new energy-saving and environmentally friendly building material, foam concrete is now widely used in wall construction.

[0005] At present, in the installation process of indoor ALC wall panels, workers first need to use a cart to transport the wall panels to the location where they need to be installed, and then process the surface and fixings of the wall panels, and then clean the dust and foreign matter on the installation ground. Then, they manually stand up the wall panels for preliminary positioning and add wooden pads at the bottom. Then, they use an L-shaped crowbar to extend into the bottom of the wall panel for more precise angle adjustment, and finally make the center line of the wall panel coplanar with the ink line on the ground. Then, they screw the fixings to the building wall, and then cast the bottom and smooth the walls on both sides with plastering. Only then can the installation of the ALC wall panels be considered completed.

[0006] However, in actual operation, when the crowbar is used to adjust the left and right swing angles between the wall panel and the ink line, the accuracy of the adjustment depends entirely on the worker's naked eye. This method will accumulate errors when encountering long-distance wall installation, causing the entire wall surface to bend and uneven, ultimately affecting the acceptance results. Therefore, in order to ensure the final quality of LAC wall panel installation and improve the rigor of the work, we have specially designed an ALC wall panel installation device and operation method.

[0029] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the following will be a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work shall fall within the scope of protection of the present invention.

[0030] This embodiment discloses Figures 1 to 5 The ALC wall panel installation device shown in the figure includes a controller (not shown), a display 10 (the controller is integrated into the display housing), a reference base 20, a rotating shaft 30 horizontally arranged on the reference base 20, a wall panel support base 40 longitudinally hinged at the upper end of the rotating shaft 30, and a lever armrest 50 inclined upward at the rear end of the wall panel support base 40; wherein, the reference base 20 is a rectangular steel plate, and the lever armrest 50 has a certain length and a downwardly bent portion 51 at its top end for human handholding; and the display 10 is arranged at the upper end of the lever armrest 50 and on the lower side of the bent portion 51, for displaying necessary parameters and information.

[0031] Furthermore, the front end of the wall panel support seat 40 has a docking position 4a for the lower end of the wall panel to dock, and the docking position 4a generally has a wider horizontal surface for the bottom surface of the wall panel to fit; the rear end of the wall panel support seat 40 has a first light-emitting unit 60 that emits a longitudinal surface beam backward; a second light-emitting unit 70 that emits a longitudinal surface beam backward is fixedly provided on the reference base 20 at the rear side of the rotating shaft 30; the upper end of the wall panel support seat 40 is provided with a third light-emitting unit 80 that emits a longitudinal surface beam forward, and the first light-emitting unit 60, the second light-emitting unit 70 and the third light-emitting unit 80 are all laser units carrying collimators. The light module is a light module, and the light colors of the first light emitting unit 60 and the second light emitting unit 70 are two different colors. Generally, the light colors of the first light emitting unit 60 and the third light emitting unit 80 are fluorescent green, and the light beam color of the second light emitting unit 70 is red. The green light of the first light emitting unit 60 and the red light of the second light emitting unit 70 overlap to form yellow light (optical additive mixing principle). The reason for using red and green light colors is mainly to play a striking role and facilitate observation by operators; of course, other light colors can also be used, as long as the purpose of forming a new color light after the two beams of light are mixed can be achieved.

[0032] The controller uses an STM32F407VGT6, which can process encoder data, control laser pulses, and execute a mixed light intensity algorithm. The display uses a 5-inch screen and supports an SPI interface for real-time display of deflection angle, laser power, and ambient light level. The two light-emitting units are driven by an LM3410X (red / green light) laser driver IC, which uses a constant current output of 1.5A and a PWM dimming frequency of 1kHz.

[0033] The present invention utilizes two light beams of different colors to merge to form a new color light beam, thereby being able to clearly confirm the adjustment angle of the wall panel. Compared with the traditional method of observation with the naked eye, the installation accuracy of the wall panel can be significantly improved; the specific implementation steps are: placing the reference base 20 on the ground and extending the wall panel support base 40 into the bottom of the wall panel so that it is docked on the docking position 4a, and then adjusting the reference base 20 so that the longitudinal surface light beam emitted by the second light-emitting unit 70 coincides with the ink line on the ground and uses this as the adjustment reference, at this time, operating the lever armrest 50 to rotate the wall panel support base 40 left and right around the rotating shaft 30, driving the light beam of the first light-emitting unit 60 and the light beam of the second light-emitting unit 70 to produce relative displacement, when the light beams of different colors of the first light-emitting unit 60 and the second light-emitting unit 70 coincide, a third color light beam can be formed, at this time the operator can know that the adjustment is in place, at this time the light beam of the third light-emitting unit 80 is also in a coincident state with the median perpendicular of the side of the wall panel, so as to further confirm that the upper and lower ends of the wall panel are both collinear with the ink line on the ground, realizing the adjustment of line and surface coplanarity.

[0034] In this embodiment, the optical axis of the first light-emitting unit 60 is perpendicular to the rotation axis 30 of the wall panel support base 40. This design allows the light beam of the first light-emitting unit 60 to be used to detect the left and right margins between the wall panel support base 40 and the rotation axis 30 caused by strong use, so that the operator can deal with margin errors in advance and further ensure the accuracy of subsequent operations. Among them, the first light-emitting unit 60 also has a sensing window 61 for receiving the new color light beam formed after the light beams of the first light-emitting unit 60 and the second light-emitting unit 70 overlap (and the longitudinal surface light beam is emitted from its collimated light outlet 62). It has a photosensor inside for receiving the yellow light formed after the mixing, and is used to send information to the controller when receiving the yellow light signal, so that the controller can display the status of the red and green light beams overlapping to the operator through the display 10 or the sound and light module, so that the operator can adjust it in place as soon as it finds it; among them, the photosensor uses a high-sensitivity photodiode (such as BPW34) in conjunction with an operational amplifier (such as LM358) to form a comparison circuit, and outputs a high-level signal to the controller when yellow light is detected. During the process, the photosensor also needs to adjust the threshold potentiometer to adapt to different ambient light conditions.

[0035] In this embodiment, the device also includes a hollow encoder 90 (POSICEC35); the movable end of the hollow encoder 90 is coaxially fixedly connected to the rotating shaft 30, and the fixed end of the hollow encoder 90 is relatively fixed to the reference base 20; in the initial state, the 0-degree angle posture state of the hollow encoder 90 corresponds to the overlapping state of the light beams of the first light-emitting unit 60 and the second light-emitting unit 70, which serves as the adjustment reference state; specifically, during the adjustment process, the hollow encoder 90 is used to detect the rotation angle of the rotating shaft 30 in real time and transmit the angle change data to the controller, and the controller displays these change data through the display 10, so that the operator can grasp the adjustment status of the wall panel in real time.

[0036] In this embodiment, the parking position 4a is a recessed step, and the transverse end face a1 of the step is perpendicular to the longitudinal end face a2 (vertical surface). When the left and right deflection angles of the wall panel are adjusted into place, the light beams of the first light-emitting unit 60 and the second light-emitting unit 70 overlap and are coplanar with the light beam of the third light-emitting unit 80, and the side wall of the wall panel is parallel to the vertical surface of the step. At this time, through the combination of the three light-emitting units and the fitting of the vertical surface of the step, the left and right swing accuracy of the wall panel can be determined in multiple dimensions, which can significantly improve the installation quality of the wall panel.

[0037] In this embodiment, the front end of the wall panel support seat 40 is detachably connected to the split part 41, and the docking position 4a is arranged on the front end surface of the split part 41. Specifically, the wall panel support seat 40 is a triangular structure with its inclined surface facing forward. The split part is also triangular and is mounted on the front end of the wall panel support seat 40. The two can be connected by bolts. The design of the split structure can facilitate the replacement of the adapted split part 41 according to the different thicknesses of the wall panel, thereby ensuring the adaptability of the docking position 4a to the lower end of the wall panel and reducing damage to the installation of the wall panel.

[0038] In this embodiment, the lower surface of the wall panel support seat 40 has a cavity 42 that passes through its rear end. The upper end of the rotating shaft 30 and the first light-emitting unit 60 are both located in the cavity 42 to provide protection for the first light-emitting unit 60. The first light-emitting unit 60 is arranged above the rear side of the second light-emitting unit 70 to avoid the first light-emitting unit 60 blocking the light beam of the second light-emitting unit 70 when moving downward, and it is also convenient to arrange the connecting wires of the first light-emitting unit 60 in the wall panel support seat 40 to achieve an internal wiring effect.

[0039] In this embodiment, the rear end of the reference base 20 has a rearward extension 21, and the extension 21 is provided with a rotation angle dial with the rotating shaft 30 as the center (generally a steel-printed scale is used to increase durability) to serve as an auxiliary display, so that the operator can more clearly observe the left and right swing angles of the wall panel; and the extension 21 can also provide the operator with a component to press down the reference base 20. In actual use, the operator steps on the extension 21 and uses his own weight to prevent the reference base 20 from moving easily. When it is necessary to move the reference base 20 forward so that the wall panel support seat 40 fits better with the wall panel, the operator can simultaneously operate the lever armrest 50 and use his foot to push the extension 21 interface forward to achieve the purpose.

[0040] In this embodiment, a handle 100 is provided at the upper end of the wall panel support base. The handle 100 is arranged longitudinally and its upper and lower ends are respectively connected to the wall panel support base and the lever armrest 50. The third light-emitting unit 80 is provided on the handle 100, and the display 10 is provided at the upper end of the lever armrest 50 so that the operator can view various parameters such as the adjusted angle; a channel 110 is provided in each of the handle 100 and the lever armrest 50 (the handle 100 and the lever armrest 50 are generally welded as one piece using a high-strength steel pipe); the bottom surface of the recessed cavity 42 has an installation cavity 421 that is connected to the channel 110, and the upper end of the first light-emitting unit 60 is provided in the installation cavity 421 so that the connecting wires of the controller and the first light-emitting unit 60, the second light-emitting unit 70 and the third light-emitting unit 80 can be installed in the channel 110 inside the handle 100 and the lever armrest 50, thereby reducing the external exposure of the connecting wires; and the recessed cavity 42 can also provide a mounting position for the power supply battery 190 of the controller and the three light-emitting units.

[0041] Specifically, the device is powered by a lithium battery (24V10Ah), and the control board integrates a DC-DC step-down module (such as LM2596) to reduce the voltage to 12V and 5V to supply different modules to ensure stability.

[0042] In this embodiment, a rotating shaft base 140 is provided on the upper surface of one end of the reference base 20, and a rotating groove 141 is provided on the upper end of the rotating shaft base 140 for the horizontal rotation of the rotating shaft 30, so that the rotating shaft base 140 forms a barrel-shaped structure with an upper opening and the inner diameter of the rotating groove 141 is adapted to the diameter of the rotating shaft 30; and two overlapping movable plates 150 are provided below the rotating shaft 30 in the rotating groove 141, and the two movable plates 150 are circular and adapted to the diameter of the rotating groove 141; further, a circumferential gap is formed between the two movable plates 150. There are multiple balls 160 evenly distributed, and the balls 160 are positioned by the coaxial annular groove 170 on the movable plate 150 and can roll freely therein; further, a bolt 180 is provided at the bottom of the reference base 20, which passes through the bottom surface of the rotating groove 141 and the movable plate 150 in sequence. The upper end of the bolt 180 is coaxially threaded with the rotating shaft 30, so as to limit the rotating shaft 30, the movable plate 150 and the balls 160 in the rotating groove 141, ensuring that the rotating shaft 30 can rotate smoothly horizontally while also facilitating the replacement of the rotating shaft 30 at different heights.

[0043] In addition, the present invention also provides an operating method of the ALC wall panel installation device, which includes the following steps: Step S0: Equipment preparation (power-on initialization) S01. Operator action: Press the device power button; S02. System Response: S021. The controller (STM32F407VGT6) starts and performs a self-test (checking the laser unit, encoder, and sensor connection status). S022. The display shows the startup screen (version number, battery level); S023. The photosensor starts detecting the ambient illumination; S024. The controller calculates the required light intensity threshold according to the ambient illumination; S025. The optical driver module (LM3410X) starts the red (12W) and green (7.5W) laser units at the default power and enters pulse mode (100Hz).

[0044] Step S1: Place the wall panels S11. Place the reference base at the predetermined location on the ground (close to the installation ink line); S12. Lift the lever armrest and push the wall panel support into the bottom of the ALC wall panel; S13. Place the lower end of the wall panel on the steps of the parking position; S14. The first light-emitting unit (forward green light) is automatically turned on, and the light beam is projected onto the ground 0.5-1 meter in front of the wall panel (to assist in aligning the ink line).

[0045] Step S2: Benchmark calibration (aligning with the ground ink line) S21. Observe the second light emitting unit (red light) beam on the reference base and slightly move the reference base so that the red light beam coincides with the ink line on the ground; S22. Step on the reference base extension to fix the position; S23. The wall panel support base 40 is rotated horizontally until the first color longitudinal planar beam emitted by the first light emitting unit 40 at the rear end of the wall panel support base completely overlaps with the second color longitudinal planar beam emitted by the second light emitting unit 70 at the rear side of the reference base 20, and a superimposed beam of a third color is formed; Step S3: Horizontal rotation adjustment (coarse adjustment) S31 fine-tune the wall panel position by lever armrest 50 so that the wall panel side walls fit parallel to the vertical surface of the docking position 4a; S32. The shaft drives the hollow encoder to rotate, transmitting the angle data (resolution 0.002°) to the controller in real time. S33. The controller controls the first light emitting unit (green light) and the second light emitting unit (red light) to continuously emit light beams; S34. The photosensor (BPW34) detects the mixed light intensity in real time. The controller compares the mixed light intensity (I_yellow) with the minimum threshold (I_min) and implements the following logic: If I_yellow is less than I_min, the display shows the angle deviation (e.g. -3.5 degrees) and continues monitoring; If I_Huang is greater than I_min, the following actions are triggered immediately: S341. Freeze the current angle value of the hollow encoder (recorded as 0 degree reference); S342. Sending a prompt sound through an external buzzer (e.g., lasting 0.5-1 second); S343. The display shows a green icon and the angle value (accurate to 1 decimal place); S344. The light unit switches to constant light mode (exits pulse mode to save power); Furthermore, step S3 also includes fine-tuning the fit (fine adjustment). S35. The operator gently pushes the lever armrest forward and backward to align the wall panel sidewall with the vertical plane of the docking position. S36. Hollow encoder detects fine-tuning angle changes (within ±1 degree); S37. The display updates the offset angle in real time (e.g., +0.3 degrees). S38. When the wall panels are properly fitted (encoder angle change ≤ 0.1 degrees for 2 seconds): a short beep is emitted through the buzzer, and the "Fitting Completed" icon is displayed on the display.

[0046] The overall logic is: The controller reads the encoder angle in real time, calculates the rotational position, and displays it on the display. When the light sensor is triggered, the controller confirms that the adjustment is in place and can be prompted by a buzzer or screen. The pulse modulation of the two light-emitting units is controlled by PWM, and the power is automatically adjusted according to the ambient light (the ambient light intensity is detected by ADC).

[0047] Furthermore, to ensure that the yellow light formed by the combined red and green light beams is more prominent and that the yellow light beam formed by the red and green light beams can still be clearly seen by the naked eye indoors during the day, we can use a specific algorithm to constrain the mixed light beam. Specifically, the constraint algorithm includes four dimensions: light intensity, power, beam width, and chromaticity, as follows: 1. Mixed light intensity constraint 1 (ensuring sufficient brightness from the intensity correlation of the three light beams): ; In the above formula, Indicates the intensity of mixed yellow light (unit: cd / ); and Indicates the intensity of red and green laser (unit: mW / ); Indicates optical efficiency (0.7~0.9, affected by atmospheric scattering); Indicates the ambient light intensity, generally calculated using a illuminance meter; Indicates the minimum visible light intensity (relative to the ambient illumination Related), specific, =A+Y (Unit: lux), this is an empirical formula, A is generally 800-1000 (in practice, we usually take the latter end point), and Y is generally 0.2-0.8 (in practice, we usually take the number around the middle end point, such as 0.5); Specific light intensity parameter change values ​​can be directly selected from the table below:

[0048] 2. Mixed light intensity constraint 2 (ensuring sufficient brightness based on the correlation between the intensity of the mixed light beam and the power of the red and green light beams): ; In the above formula, and are the power of red and green light respectively (in watts); and are the incident angles of the light beam (in degrees); Indicates the spot area of ​​yellow light (unit ) = , where w represents the beam width, L represents the light band length, and β represents the ground projection angle; K=0.35 is the visual contrast coefficient (empirical value); =200cd / Indicates the minimum brightness threshold; The specific power parameter change values ​​can be directly selected from the table below:

[0049] In the above table, and are the wavelengths of red and green light respectively. Specifically, =635nm, =532nm; and D represents the diameter of the beam emission aperture (unit: mm); it should be noted that in the two-color system, To suppress the rainbow effect; 3. Beam width matching (to ensure overlap accuracy): ; In the above formula, and Indicates the beam width of red and green lasers (unit: mm); and Indicates the vertical distance from the laser to the ground (unit: m); 4. Chromaticity stability conditions (to ensure accurate color): That is, the intensity of red light needs to be slightly higher than that of green light, because the human eye is most sensitive to green light (555nm), but red light (630nm) requires a higher intensity to balance color vision. The power of the light beam can also be allocated according to the chromaticity stability condition. In practice, pulse modulation can be added to enhance the contrast and verify whether the yellow light spot is clear at a distance of 0.5-1 meter from the front side of the wall panel.

[0050] The system workflow of this device is as follows ( Figure 4 ): Power-on self-test - read ambient light - start laser (light-emitting unit) according to constraint conditions - continuously monitor mixed light intensity (yellow light). If the yellow light meets the standard, lock the encoder's 0 angle point - fine-tune the wall panel until it fits - the display outputs adjustment OK and specific angle. If the yellow light does not meet the standard, increase the power / pulse frequency.

[0051] The control logic sequence of the system of this device is as follows Figure 5 shown.
