Description

Technical Field

[0001] This invention mainly relates to the field of panoramic sunroofs, specifically to a PLC-controlled dual-station simulation testing device for the mechanical assembly of a panoramic sunroof. Background Technology

[0002] With the upgrading of automobile consumption, panoramic sunroofs have become a core feature of mid-to-high-end cars due to their ability to significantly improve interior lighting and the sense of spaciousness, and their market penetration continues to increase. The panoramic sunroof mechanical assembly, as the core component for opening, closing, and positioning the sunroof, integrates multiple sub-components such as guide rails, drive mechanisms, sealing structures, and drainage systems. Its performance and stability directly determine the user experience and safety of the panoramic sunroof.

[0003] During the operation of specific embodiments, the inventors discovered the following defects: The existing equipment's spraying and pressurization systems are mostly controlled independently, lacking a coordinated linkage mechanism. Key parameters such as spraying pressure, rainfall, pressurization pressure, and pressure holding time rely heavily on manual adjustment, resulting in low automation. This not only increases the intensity of manual labor but also makes it easy for operational errors to lead to insufficient parameter control accuracy, such as uneven spraying coverage or excessive pressure fluctuations, which in turn affect the accuracy and consistency of the test results.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Summary of the Invention

[0021] Example

[0022] See attached document Figure 1-5 A PLC-controlled panoramic sunroof mechanical assembly dual-station simulation testing equipment includes a sunroof loading structure 1, a sealing structure 2 rotatably connected to the top of the sunroof loading structure 1, a spraying structure 3 rotatably connected to the inside of the sunroof loading structure 1, and a PLC on one side of the sunroof loading structure 1. The spray structure 3 includes a rotating pipe 301 rotatably connected to the interior of the skylight loading structure 1. Multiple rotating pipes 301 are provided, and a meshing gear 304 is provided on one side of each rotating pipe 301. Multiple rotating pipes 301 are connected via the meshing gear 304. An auxiliary pipe 302 is provided at the bottom of each rotating pipe 301, and a water spray chamber 303 is provided at the bottom of each auxiliary pipe 302. Multiple auxiliary pipes 302 are equally spaced on the rotating pipe 301. At the bottom of the rotating pipe 301, after the panoramic sunroof is sealed, the water pump is started. The water pump sends water through the inlet pipe 109 into the interior of the connecting pipe 108. The water enters the interior of the rotating pipe 301 and is sprayed out through the auxiliary pipe 302 and the spray chamber 303. The water sprays the panoramic sunroof to perform the first test on the sealing performance of the panoramic sunroof. At the same time, the motor is started. The motor drives the rotating pipe 301 to rotate through the meshing gear 304. The rotating pipe 301 drives the spray chamber 303 at the bottom to rotate, spraying different positions of the panoramic sunroof.

[0023] Furthermore, the sunroof loading structure 1 includes a bracket 101, with housings 102 on both sides of the bracket 101. An upper sealing strip 103 is provided on the top of the inner wall of the housing 102. Electric push rods 104 are provided on both sides of the outer wall of the bracket 101. A lifting rod 105 is provided at the output end of each electric push rod 104. A lower sealing strip 106 is provided between the two lifting rods 105, and the lower sealing strip 106 is slidably connected to the inner wall of the housing 102. An installation hole 107 is provided on one side of the bracket 101, and a connecting pipe 108 is provided on the other side of the bracket 101. A water inlet pipe 109 is provided at one end of each connecting pipe 108. Multiple connecting pipes 108 are provided. The spacing is distributed on one side of the housing 102. The connecting pipe 108 and the rotating pipe 301 are connected by a rotating sealing ring. When a sealing test is required for the panoramic sunroof, the panoramic sunroof is transported to the top of the lower sealing strip 106 between the two lifting rods 105. Then, the electric push rod 104 is activated, which drives the lifting rod 105 to move upward. The lifting rod 105 drives the lower sealing strip 106 to move upward, and the lower sealing strip 106 drives the panoramic sunroof to move upward. Then, the top of the panoramic sunroof fits against the bottom of the upper sealing strip 103. The upper sealing strip 103 and the lower sealing strip 106 cooperate to seal the panoramic sunroof, thereby sealing the side of the panoramic sunroof. Subsequent testing checks whether the side of the panoramic sunroof is flat.

[0024] Furthermore, the sealing structure 2 includes a lower pressure plate 201 and a rotating shaft 204. The lower pressure plate 201 is rotatably connected to one side of the top of the housing 102. A sealing ring 202 is provided at the bottom of the lower pressure plate 201, and a pressure groove 203 is provided at the top of the sealing ring 202. The rotating shaft 204 is rotatably connected to both sides of the outer wall of the housing 102. A hydraulic telescopic rod 205 is provided at the top of the rotating shaft 204, and a support bar 206 is provided at the top of the hydraulic telescopic rod 205. The support bar 206 is rotatably connected to the outer wall of the lower pressure plate 201. When the panoramic sunroof is placed inside the housing 102, the hydraulic telescopic rod 205 is activated. The hydraulic telescopic rod 205 drives the lower pressure plate 201 to move downward. The lower pressure plate 201 causes the sealing ring 202 at the bottom to fit against the inner wall of the housing 102 to seal the top of the housing 102, so that a sealed state is formed between the panoramic sunroof and the lower pressure plate 201. When there is a certain amount of water between the panoramic sunroof and the lower pressure plate 201, the pressure pump pressurizes the water inside the housing 102 through the pressure tank 203, causing the water to squeeze the panoramic sunroof and test the pressure resistance of the panoramic sunroof.

[0025] The PLC is installed on the outer side of the housing 102, specifically in the non-moving area and close to the connecting pipe 108. This installation position relies on the fixed structure of the housing 102, which facilitates wiring and protects the PLC from the spray area to avoid moisture. At the same time, its proximity to the actuators shortens the wiring distance and improves signal transmission stability.

[0026] The pressure sensor is embedded in the inner wall of the pressure groove 203 of the sealed structure and is directly connected to the closed cavity. This installation method allows the sensor to directly monitor the pressure within the closed cavity formed by the housing 102, upper sealing strip 103, lower sealing strip 106, and sealing ring 202, ensuring accurate pressure data feedback and providing a reliable basis for pressurization control.

[0027] The liquid level sensor is installed in the middle of the inner wall of the housing 102, specifically 5-10 cm below the upper sealing strip 103, avoiding the direct spray area. This location allows for real-time monitoring of the spray water level inside the cavity, preventing data fluctuations caused by direct spray from the spray chamber 303, ensuring the accuracy of water level detection, and enabling timely triggering of the water pump's start and stop actions.

[0028] Photoelectric sensors are installed on both sides of the inner wall of housing 102, corresponding to the feeding inlet side above lifting rod 105. The purpose of their installation is to accurately detect whether the panoramic sunroof has been delivered to the preset feeding position at the top of the lower sealing strip 106. Once the sunroof is detected to be in place, a signal is sent in time to trigger the subsequent sealing action, ensuring a smooth connection between the feeding and sealing processes.

[0029] The motor driving the rotating tube 301 is mounted on one side of the bracket 101, on the same side as the meshing gear 304, and is directly connected to one of the rotating tubes 301 via a coupling. This mounting method allows the motor power to be directly transmitted to the meshing gear 304, thereby driving the rotation of multiple rotating tubes 301, reducing power transmission loss, and conforming to the optimization logic of mechanical transmission.

[0030] The water pump used for spray water supply is installed on an external auxiliary frame of the equipment, with one end connected to the inlet pipe 109 and close to the connecting pipe 108. Installing the water pump externally facilitates daily maintenance and avoids interference with the spray area inside the equipment, ensuring a stable and orderly water supply process.

[0031] The pressurizing pump is also mounted on an external auxiliary frame of the equipment and connected to the inlet of the pressurizing tank 203 via a dedicated pipeline. This installation design, away from the enclosed cavity, avoids pump vibration affecting detection accuracy during pressurization. Simultaneously, it allows for the smooth injection of compressed air into the cavity through the pressurizing tank 203, ensuring uniformity in the pressurization process.

[0032] The core of the entire equipment is the PLC, forming a complete control link of "sensor → PLC (signal input) → PLC → actuator (control output)". All components are connected through internal wiring channels. The power supply is uniformly provided by 220V / 380V industrial power. The PLC needs to be converted to 24V DC power by a switching power supply to ensure that the power supply of each component is stable and matches its operating voltage requirements.

[0033] The PLC and pressure sensor are connected via shielded signal cables. The pressure sensor outputs a 4-20mA analog signal, which is connected to the PLC's analog input port (AI). The pressure sensor collects pressure data from the enclosed cavity in real time and transmits it to the PLC. The PLC uses its built-in PID algorithm to adjust the pressure of the booster pump, ensuring that the pressurization pressure remains stable within the set range.

[0034] The PLC and the level sensor are connected via signal lines. Depending on the type of level sensor, it can be connected to either the PLC's digital input port (DI) or analog input port (AI). If it is a digital level sensor, it will send a "high level" signal to the PLC when the water level reaches the target, triggering the water pump to stop working. If it is an analog level sensor, it will transmit water level data to the PLC in real time, allowing the PLC to accurately control the spraying process.

[0035] The PLC and photoelectric sensor are connected via signal lines, and the signal output terminal of the photoelectric sensor is connected to the digital input port (DI) of the PLC. When the photoelectric sensor detects that the sunroof is in position, it immediately sends a "trigger signal" to the PLC. After receiving the signal, the PLC starts the electric push rod 104 to perform the lifting action to complete the side sealing of the sunroof.

[0036] The PLC is connected to the motor driving the rotary tube 301 via a link of "motor → frequency converter → PLC". The motor is connected to the frequency converter, and the control terminals of the frequency converter are connected to the digital output port (DO) and analog output port (AO) of the PLC. The PLC controls the start and stop of the motor through the digital output port (DO) and outputs a 0-10V signal through the analog output port (AO) to adjust the frequency converter, thereby achieving speed control of 5-10 r / min to meet the full coverage requirements of the rotating spray system.

[0037] The PLC and the sprinkler pump are connected via a link of "pump → relay → PLC". The control terminal of the relay is connected to the digital output port (DO) of the PLC. When the PLC receives a "low water level" signal from the level sensor, it controls the relay to activate and start the water pump to supply water; when it receives a "high water level" signal, it controls the relay to deactivate and shut down the water pump to stop the water supply, thus realizing automatic control of the sprinkler water volume.

[0038] The PLC and the booster pump are connected via a link: "booster pump → contactor + frequency converter → PLC". The control terminals of the contactor and frequency converter are connected to the PLC's digital output (DO) port and analog input (AI) port, respectively. The PLC controls the start and stop of the booster pump through the digital output (DO) port and receives feedback data from the pressure sensor through the analog input (AI) port, adjusting the frequency converter output to stabilize the pressure within the set range of 0.6-0.8 MPa.

[0039] The PLC and the electric push rod 104 are connected via an electric push rod 104 driver. The control terminal of the driver is connected to the digital output port (DO) of the PLC. The PLC controls the driver to operate based on the signal from the photoelectric sensor, driving the electric push rod 104 to extend or retract, thereby adjusting the stroke of the lifting rod 105 to realize the raising and lowering of the sunroof and the side sealing.

[0040] The PLC and the hydraulic telescopic rod 205 are connected via a hydraulic driver, and the control terminal of the hydraulic driver is connected to the digital output port (DO) of the PLC. The PLC controls the hydraulic driver to drive the hydraulic telescopic rod 205 to extend and retract, thereby realizing the flipping and sealing action of the lower pressure plate 201 and ensuring the sealing effect of the top of the closed cavity.

[0041] Device initialization and parameter setting Start the PLC control system, and the operator inputs the detection parameters through the touch screen: spray pressure (0.3-0.5MPa), rainfall (5-8L / min), spray duration (3-5min), pressurization pressure (0.6-0.8MPa), and pressure holding time (2-3min). The equipment automatically stores the parameters and calibrates the sensors (pressure sensor, liquid level sensor, and photoelectric sensor). The dual workstations (workstation A and workstation B) are in standby mode. The lifting rod 105 of the skylight loading structure 1 has fallen back to the lowest position. The lower pressure plate 201 of the sealing structure 2 is in the open state. The rotating pipe 301 of the spray structure 3 has been reset to the initial position.

[0042] Alternating feeding at dual workstations The conveyor belt transports the panoramic sunroof to be tested to the bracket 101 above workstation A and workstation B respectively. After the PLC confirms that the sunroof is in place through the photoelectric sensor, it controls the electric push rod 104 to start. The electric push rod 104 drives the lifting rod 105 to move upward, which in turn causes the lower sealing strip 106 and the sunroof to rise synchronously until the top of the sunroof is tightly sealed with the upper sealing strip 103 on the inner wall of the housing 102, thus completing the side sealing of the sunroof (adapting to different sizes of sunroofs: the stroke of the electric push rod 104 can be adjusted by PLC to achieve compatibility with sunroofs with a width of 500-1200mm).

[0043] Top seal and cavity closure The PLC controls the rotating shaft 204 to extend the hydraulic telescopic rod 205, pushing the support bar 206 to cause the lower pressure plate 201 to flip downward until the sealing ring 202 at the bottom of the lower pressure plate 201 is completely in contact with the top edge of the housing 102; The sealing ring 202, together with the upper sealing strip 103 and the lower sealing strip 106, forms a closed cavity to ensure that there is no water or air leakage during the testing process.

[0044] Rotary spray single test The PLC starts the external water pump, and water enters the rotating pipe 301 through the inlet pipe 109 and the connecting pipe 108 (the rotating sealing ring ensures a seal when rotating). It is then sprayed evenly from the spray chamber 303 through the equally spaced auxiliary pipes 302 to fully cover the surface of the sunroof. At the same time, the PLC controls the start of the drive motor, which drives multiple rotating tubes 301 to rotate synchronously (5-10 r / min) through meshing gear 304, ensuring that there are no dead angles in the spraying; The liquid level sensor monitors the water level in the cavity in real time. Once the water level reaches the preset height (80% of the skylight surface area), the sensor sends the feedback to the PLC, and the water pump automatically stops supplying water, ending the spraying phase.

[0045] Secondary pressure testing The PLC starts the external pressure pump and injects compressed air into the closed cavity through the pressure groove 203 at the top of the sealing ring 202, gradually increasing the pressure inside the cavity to the set value; The pressure sensor provides real-time pressure data, and the PLC adjusts the output of the booster pump through a PID algorithm to ensure that the pressure fluctuation range is ≤ ±0.02MPa and maintains the pressure holding time. During the pressure holding period, the PLC monitors for any pressure drop (the basis for determining leakage) and records the pressure change curve simultaneously.

[0046] Pressure relief, material discharge, and feedback of test results After the pressure holding is completed, the PLC controls the pressure relief valve of the pressure tank 203 to open, slowly releasing the pressure in the chamber to normal pressure. Then, the PLC controls the hydraulic telescopic rod 205 to retract and the lower pressure plate 201 to open. The electric push rod 104 drives the lifting rod 105 to fall back, and the lower sealing strip 106 drives the skylight that has completed the inspection to descend to the conveyor belt. The conveyor belt transports the skylight to the unloading area (qualified products are marked with a green label, and unqualified products are alerted by the PLC linkage alarm device and the location of the leak is marked). When station A completes the inspection, station B simultaneously enters the spraying stage. The two stations alternate in a cycle to improve inspection efficiency (the inspection cycle of a single station is 8-10 minutes, and the capacity of the two stations is increased by more than 80%).

[0047] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
