Description

Technical Field

[0001] The present invention relates to the technical field of mechanical automated assembly, and in particular to an assembly device and method for an electronic mechanical brake caliper MGU planetary gear train. Background Art

[0002] Currently, in the process of assembling the planetary gear train of the electromechanical brake caliper, the traditional method mainly relies on manual or semi-automatic assembly, which has the following problems: 1) Low assembly accuracy: Manual operation makes it difficult to ensure the precise meshing of the planetary gear and the planetary gear carrier ring gear, which can easily lead to misalignment or tooth jamming. 2) Inefficiency: Manual adjustments and repeated trial installations take a long time and are difficult to meet mass production requirements; 3) Unstable quality: Lack of real-time force feedback and excessive assembly pressure can easily lead to deformation or damage of parts; 4) Insufficient automation: Existing equipment mostly relies on fixed-path assembly and cannot dynamically adjust to accommodate slight deviations.

[0003] While some existing automated assembly systems can achieve initial positioning of planetary gears, they lack intelligent feedback mechanisms and are unable to address the force control issues during dynamic meshing. Therefore, a high-precision, intelligent assembly solution is urgently needed to improve the assembly quality and efficiency of planetary gear trains. Summary of the Invention

[0004] The purpose of the present invention is to provide an automated assembly device and method for an electromechanical brake caliper (MGU) planetary gear train. Through three-axis precise positioning, dynamic tooth engagement, and real-time pressure monitoring, the device solves the tooth sticking problem in traditional assembly and improves assembly accuracy, efficiency, and quality.

[0005] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: The electromechanical brake caliper MGU planetary gear train assembly device includes a planetary gear carrier fixing module and a planetary gear assembly module. The planetary gear assembly module is provided with a three-axis assembly mechanism. The three-axis assembly mechanism includes a motion drive component and a rotation component. The rotation component is connected to the planetary gear gripper. The three-axis assembly mechanism is provided with a pressure sensor and a photoelectric sensor. The photoelectric sensor is used to detect the alignment state of the tooth gap between the planetary gear and the planetary gear carrier ring gear in real time, and feedback control the movement of the planetary gear gripper to achieve dynamic tooth engagement. The pressure sensor is used to monitor the press-fitting force in real time. The present invention realizes the precise positioning and assembly of the planetary gear in three-dimensional space through the three-axis assembly mechanism and its motion drive component and rotation component, significantly improving the assembly accuracy and efficiency and solving the tooth jamming problem of traditional static assembly. The motion drive component ensures that the planetary gear moves along a preset path, while the rotation component controls the rotation angle of the planetary gear so that it is perfectly engaged with the ring gear of the planetary gear carrier. The introduction of pressure sensors enables real-time monitoring of pressure changes during assembly. When the planetary gears align with the ring gear of the planetary carrier, a photoelectric sensor detects successful alignment, while a pressure sensor monitors the meshing pressure in real time, forming an intelligent feedback system to prevent deformation or damage to components due to excessive pressure. During the press-fit process after engagement, the pressure is monitored in real time to prevent overload damage. This invention reduces manual intervention and assembly errors through mechanical automation, making it suitable for high-precision planetary gear assembly scenarios in electromechanical brake calipers (MGUs).

[0006] Specifically, the planetary carrier fixing module includes a lifting mechanism that supports the planetary carrier. Above the lifting mechanism is a planetary carrier positioning mechanism for circumferentially limiting the carrier. The lifting mechanism raises the planetary carrier to the working height, while the planetary carrier positioning mechanism prevents it from shifting or shaking through circumferential limits, improving the carrier's stability during assembly.

[0007] Specifically, the system also includes a slide loading mechanism equipped with a planetary gear loading and positioning fixture, which can drive the movement of the planetary gear loading and positioning fixture. The present invention utilizes the slide loading mechanism and the planetary gear loading and positioning fixture to achieve automatic loading and precise positioning of the planetary gears. The slide loading mechanism can quickly transport the planetary gears to the assembly station, improving assembly efficiency. The automated loading process reduces human error and ensures consistency and reliability of the assembly process.

[0008] Specifically, the three-axis assembly mechanism is provided with three mutually perpendicular axes, which can perform translational motion in three-dimensional space along a rectangular coordinate system composed of X, Y, and Z directions.

[0009] Specifically, the motion drive assembly is a servo press.

[0010] The assembly method of the electromechanical brake caliper MGU planetary gear train includes the following steps: The planetary wheel carrier fixing module fixes the planetary wheel carrier; The planetary wheel gripper grabs the planetary wheel to the top of the planetary wheel frame fixing module, drives the planetary wheel to rotate and descend, and automatically adjusts the assembly path and angle of the planetary wheel according to the preset program; The planetary gear meshes with the ring gear of the planetary gear carrier, and the planetary gear gripper floats up and down. The photoelectric sensor detects the meshing status of the planetary gear and the ring gear. When the photoelectric sensor detects no signal, the planetary gear gripper drives the planetary gear to rise, rotate, and descend to re-align the gears. When the photoelectric sensor detects a signal, the planetary gear gripper drives the planetary gear to continue to descend, and the motion drive assembly presses the planetary gear into the planetary gear carrier. The pressure sensor monitors the pressure in real time. When the detected value is lower or higher than the set value, the system alarms; The planetary gear gripper grabs the second planetary gear and installs it into the planetary gear carrier, and repeats this action until all three planetary gears are installed in the planetary gear carrier.

[0011] Specifically, if the preset pressing depth is not reached and the pressure exceeds the preset pressing value, it is determined that the pressing is not smooth, and the planetary wheel gripper drives the planetary wheel to rise for debugging. If the pressure reaches the preset pressing value after the preset pressing depth is reached, it is determined that the pressing is smooth, and the planetary wheel gripper stops descending and releases the planetary wheel to avoid excessive pressing force.

[0012] The beneficial effects of the present invention are as follows: the present invention realizes the automatic meshing of the planetary wheels and the ring gear of the planetary wheel carrier by driving the planetary wheels to slowly rotate and descend through the planetary wheel gripper. This dynamic assembly method can effectively solve the common tooth jamming problem in traditional static assembly, and significantly improve the assembly success rate and efficiency. Through the monitoring of photoelectric sensors and pressure sensors, real-time data feedback enables the system to dynamically adjust the gear alignment and press-fitting parameters to prevent parts from being damaged or improperly assembled, ensuring that the planetary wheels are smoothly pressed into the bottom of the planetary wheel carrier, avoiding damage to parts or assembly failure due to excessive assembly force, and improving assembly quality and equipment service life. In the present invention, the planetary wheel gripper completes the grabbing, gear alignment and press-fitting of multiple planetary wheels in sequence according to a preset program. The continuous automated assembly of three planetary wheels significantly improves production efficiency and ensures the consistency and reliability of the assembly process.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The following first describes the concepts involved in this application with reference to the accompanying drawings. It should be noted that the following description of each concept is intended only to make the content of this application easier to understand and does not limit the scope of protection of this application. At the same time, the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The following detailed description of this application will be made with reference to the accompanying drawings and in conjunction with the embodiments.

[0024] Example 1 like Figure 1 and Figure 2As shown, the planetary gear train assembly device of the electronic mechanical brake caliper MGU includes a planetary gear carrier fixing module and a planetary gear assembly module. The planetary gear assembly module is provided with a three-axis assembly mechanism 5. The three-axis assembly mechanism 5 includes a motion drive component 51 and a rotation component 52. The rotation component 52 is connected to the planetary gear gripper 55. The three-axis assembly mechanism 5 is provided with a pressure sensor 54 and a photoelectric sensor 56. Figure 4 This is a schematic diagram of the two-axis module of the three-axis assembly mechanism. Figure 5 This is a cross-sectional view of the two-axis module of the three-axis assembly mechanism. This invention utilizes the three-axis assembly mechanism 5, its motion drive assembly 51, and its rotation assembly 52 to achieve precise positioning and assembly of planetary gears in three dimensions, significantly improving assembly accuracy and efficiency and resolving the tooth-binding problem associated with traditional static assembly. The motion drive assembly 51 ensures the planetary gears move along a preset path, while the rotation assembly 52 controls the planetary gears' rotation angles to ensure perfect meshing with the planetary gear carrier's ring gear. The introduction of a pressure sensor 54 enables real-time monitoring of pressure changes during the assembly process. As the planetary gears align with the planetary gear carrier's ring gear, the system, in conjunction with a photoelectric sensor 56, monitors the meshing status and automatically adjusts the assembly path. If meshing is not achieved, the mechanism rises to prevent damage to the product. Once meshing is achieved, the mechanism automatically descends, forming an intelligent feedback system to prevent deformation or damage to components caused by excessive pressure. During the press-fit process of the planetary gears after meshing, the system monitors the pressing force in real time to prevent overload damage. This invention reduces manual intervention and assembly errors through mechanical automation, making it suitable for high-precision planetary gear assembly scenarios in electromechanical brake calipers (MGUs).

[0025] like Figure 3 As shown, the planetary carrier fixing module includes a lifting mechanism 1 that supports the planetary carrier. Above the lifting mechanism 1 is a planetary carrier positioning mechanism 2 for circumferentially limiting the planetary carrier. The lifting mechanism 1 raises the planetary carrier to the working height, while the planetary carrier positioning mechanism 2 prevents it from shifting or shaking through circumferential limiting, thereby improving the stability of the planetary carrier during assembly.

[0026] The electromechanical brake caliper (MGU) planetary gear train assembly device also includes a slide loading mechanism 4, mounted with a planetary gear loading and positioning tool 3. This mechanism drives the planetary gear loading and positioning tool 3. The present invention utilizes the slide loading mechanism 4 and the planetary gear loading and positioning tool 3 to achieve automatic loading and precise positioning of the planetary gears. The slide loading mechanism 4 rapidly transports the planetary gears to the assembly station, improving assembly efficiency. The automated loading process reduces operator error and ensures consistency and reliability during the assembly process.

[0027] The three-axis assembly mechanism 5 is provided with three mutually perpendicular axes 53, which can perform translational motion in three-dimensional space along a rectangular coordinate system composed of X, Y, and Z directions.

[0028] A lifting and floating spring assembly 57 is connected above the planetary gear gripper 55 to achieve up and down floating during the process of meshing the planetary gear and the planetary gear carrier ring gear. The lifting and floating spring assembly 57 uses an elastic floating design to enable the planetary gear gripper 55 to float slightly up and down during the process of meshing the planetary gear and the planetary gear carrier ring gear. When the photoelectric sensor does not detect the meshing signal, the compression / rebound action of the spring assists the planetary gear gripper to quickly adjust its position, shortening the debugging time. In addition, the lifting and floating spring assembly 57 can solve the problem of rigid alignment being easily stuck in high-precision assembly through flexible adjustment and dynamic buffering: when there is a slight misalignment between the teeth, the flexible deformation of the spring can automatically compensate for the position deviation, avoid tooth jamming or part damage caused by rigid contact, and significantly improve the success rate of tooth alignment. During the press-fitting process, the lifting and floating spring assembly 57 can absorb the instantaneous impact force caused by assembly path deviation or part size error, disperse the pressure through elastic deformation, prevent the system from false alarming or part overload damage caused by a sudden increase in the detection value of the pressure sensor 54, and ensure that the pressing force is stable and controllable.

[0029] The motion driving component 51 is a servo press.

[0030] The assembly method of the electromechanical brake caliper MGU planetary gear train includes the following steps: S1. Planetary wheel carrier fixing module fixes the planetary wheel carrier: jacking mechanism 1 lifts and positions the planetary wheel carrier, and the planetary wheel carrier positioning mechanism 2 limits the planetary wheel carrier; S2. The planetary wheel gripper 55 grabs the planetary wheel from the planetary wheel loading and positioning tool 3 to the planetary wheel frame fixing module above, driving the planetary wheel to rotate while descending, automatically adjusting the planetary wheel assembly path and angle according to the preset program; S3. The planetary gear meshes with the ring gear of the planetary gear carrier. The planetary gear gripper 55 floats up and down, and the photoelectric sensor 56 detects the meshing status of the planetary gear and the ring gear. When the photoelectric sensor 56 detects no signal, the planetary gear gripper 55 drives the planetary gear to rise, rotate, and descend to re-align the gears. When the photoelectric sensor 56 detects a signal, the planetary gear gripper 55 drives the planetary gear to continue to descend, and the motion drive assembly 51 presses the planetary gear into the planetary gear carrier. S4. The pressure sensor 54 monitors the pressure in real time. When the detected value is lower or higher than the set value, the system alarms; S5. The planetary gear gripper 55 grabs the second planetary gear and installs it into the planetary gear carrier. Repeat this action until all three planetary gears are installed in the planetary gear carrier.

[0031] The application realizes automatic meshing of the planetary gear and the gear ring of the planetary gear carrier by the way of the planetary gear gripper 55 driving the planetary gear to rotate and descend slowly, and this dynamic assembly method can effectively solve the common tooth jamming problem in traditional static assembly, significantly improve the assembly success rate and efficiency. Through the monitoring of the photoelectric sensor 56 and the pressure sensor 54, real-time data feedback enables the system to dynamically adjust the meshing and pressing parameters, prevents part damage or assembly out of position, ensures that the planetary gear is smoothly pressed into the bottom of the planetary gear carrier, avoids part damage or assembly failure caused by excessive assembly force, and improves the assembly quality and equipment service life. In the application, the planetary gear gripper 55 completes the grasping, meshing and pressing of multiple planetary gears according to the preset program, and the continuous automatic assembly of the three planetary gears significantly improves the production efficiency and ensures the consistency and reliability of the assembly process.
