Description

Technical Field

[0001] This invention relates to the field of mechanical automation assembly technology, specifically to an assembly device and method for an electromechanical brake caliper MGU planetary gear train. Background Technology

[0002] Currently, in the assembly process of planetary gear trains for electromechanical brake calipers, traditional methods mainly rely on manual or semi-automated assembly, which has the following problems:

[0003] 1) Low assembly precision: Manual operation makes it difficult to ensure the precise meshing of the planetary gears and the planetary gear carrier ring gear, which can easily lead to misalignment or jamming.

[0004] 2) Inefficiency: Manual adjustments and repeated trial assembly are time-consuming and difficult to meet the needs of mass production;

[0005] 3) Unstable quality: Lack of real-time force feedback, excessive assembly pressure can easily lead to deformation or damage of parts;

[0006] 4) Insufficient automation: Existing equipment mostly relies on fixed assembly paths and cannot be dynamically adjusted to adapt to minor deviations.

[0007] While some existing automated assembly devices can achieve initial positioning of planetary gears, they lack intelligent feedback mechanisms and cannot solve the force control problem 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

[0008] The purpose of this invention is to provide an automated assembly device and method for an electromechanical brake caliper MGU planetary gear train. By using three-axis precise positioning, dynamic gear meshing, and real-time pressure monitoring, it solves the problem of gear jamming in traditional assembly and improves assembly accuracy, efficiency, and quality.

[0009] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0010] The MGU planetary gear system assembly device for electromechanical brake calipers includes a planetary gear carrier fixing module and a planetary gear assembly module. The planetary gear assembly module has a three-axis assembly mechanism, which includes a motion drive component and a rotation component. The rotation component is connected to a planetary gear gripper. The three-axis assembly mechanism is equipped with a pressure sensor and a photoelectric sensor. The photoelectric sensor is used to detect the tooth backlash alignment between the planetary gears and the planetary gear carrier ring gear in real time and provides feedback to control the movement of the planetary gear gripper to achieve dynamic tooth engagement. The pressure sensor is used to monitor the pressing force in real time. This invention, through the three-axis assembly mechanism and its motion drive and rotation components, achieves precise positioning and assembly of planetary gears in three-dimensional space, significantly improving assembly accuracy and efficiency, and solving the tooth jamming problem of traditional static assembly. The motion drive component ensures that the planetary gears move along a preset path, while the rotation component controls the rotation angle of the planetary gears to ensure perfect engagement with the planetary gear carrier ring gear. 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 gear carrier, photoelectric sensors detect successful alignment, while pressure sensors monitor the meshing pressure in real time, forming an intelligent feedback system to prevent deformation or damage to parts due to excessive pressure; during the pressing-in process of the planetary gears after meshing, the pressing force 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 assembly scenarios of electromechanical brake calipers (MGU) planetary gear systems.

[0011] Specifically, the planetary gear carrier fixing module includes a lifting mechanism that supports the planetary gear carrier, and a planetary gear carrier positioning mechanism above the lifting mechanism for circumferentially limiting the planetary gear carrier. The lifting mechanism raises the planetary gear carrier to the working height, while the planetary gear carrier positioning mechanism prevents it from shifting or shaking through the circumferential limiting function, thereby improving the stability of the planetary gear carrier during the assembly process.

[0012] Specifically, it also includes a slide-table loading mechanism, which is equipped with a planetary gear loading and positioning fixture. The slide-table loading mechanism can drive the planetary gear loading and positioning fixture to move. This invention achieves automatic loading and precise positioning of planetary gears through the slide-table loading mechanism and the planetary gear loading and positioning fixture. The slide-table loading mechanism can quickly transport planetary gears to the assembly station, improving assembly efficiency. The automated loading process reduces human error and ensures the consistency and reliability of the assembly process.

[0013] Specifically, the three-axis assembly mechanism has three mutually perpendicular axes, which can perform translational movements in three-dimensional space along a rectangular coordinate system composed of the X, Y, and Z directions.

[0014] Specifically, the motion drive component is a servo press.

[0015] The assembly method for the MGU planetary gear train of the electromechanical brake caliper includes the following steps:

[0016] The planetary gear carrier fixing module secures the planetary gear carrier;

[0017] The planetary gear gripper picks up the planetary gears and places them above the planetary gear carrier fixing module, causing the planetary gears to rotate and descend simultaneously. The assembly path and angle of the planetary gears are automatically adjusted according to a preset program.

[0018] The planetary gear meshes with the gear ring of the planetary gear carrier. The planetary gear gripper moves up and down, and the photoelectric sensor detects the meshing status of the planetary gear and the gear ring: when the photoelectric sensor does not detect a signal, the planetary gear gripper drives the planetary gear to rise, rotate and fall to re-align the gears; when the photoelectric sensor detects a signal, the planetary gear gripper drives the planetary gear to continue to fall, and the motion drive component presses the planetary gear into the planetary gear carrier.

[0019] The pressure sensor monitors the pressure in real time, and the system alarms when the detected value is lower or higher than the set value.

[0020] The planetary gear gripper picks up the second planetary gear and inserts it into the planetary gear carrier. This action is repeated until all three planetary gears are in the planetary gear carrier.

[0021] Specifically, if the pressure exceeds the preset pressing value before the preset pressing depth is reached, it is determined that the pressing is not smooth. The planetary gear gripper drives the planetary gear to rise and adjust. If the pressure reaches the preset pressing depth and the preset pressing value is reached, it is determined that the pressing is smooth. The planetary gear gripper stops descending and releases the planetary gear to avoid excessive pressing force.

[0022] The beneficial effects of this invention are as follows: This invention achieves automatic gear engagement between the planetary gears and the planetary gear carrier ring by using a planetary gear gripper to slowly rotate and descend the planetary gears. This dynamic assembly method effectively solves the common gear jamming problem in traditional static assembly, significantly improving assembly success rate and efficiency. Through monitoring by photoelectric and pressure sensors, real-time data feedback allows the system to dynamically adjust gear engagement and pressing parameters, preventing damage to parts or improper assembly. This ensures that the planetary gears are smoothly pressed into the bottom of the planetary gear carrier, avoiding damage to parts or assembly failure due to excessive assembly force, thus improving assembly quality and equipment lifespan. In this invention, the planetary gear gripper sequentially completes the gripping, gear engagement, and pressing of multiple planetary gears according to a preset program. The continuous automated assembly of three planetary gears significantly improves production efficiency and ensures the consistency and reliability of the assembly process.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] Example 1

[0035] like Figure 1 and Figure 2As shown, the electromechanical brake caliper MGU planetary gear system 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 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 a 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 a two-axis module of a 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, through the three-axis assembly mechanism 5 and its motion drive component 51 and rotary component 52, achieves precise positioning and assembly of planetary gears in three-dimensional space, significantly improving assembly accuracy and efficiency, and solving the problem of gear jamming in traditional static assembly. The motion drive component 51 ensures the planetary gears move along a preset path, while the rotary component 52 controls the rotation angle of the planetary gears, ensuring perfect meshing with the gear ring of the planetary gear carrier. The introduction of the pressure sensor 54 enables real-time monitoring of pressure changes during the assembly process: when the planetary gears align with the gear ring of the planetary gear carrier, the photoelectric sensor 56 monitors the meshing status in real time and automatically adjusts the assembly path. If the meshing is not good, the mechanism floats up to prevent damage to the product; after proper meshing, the mechanism automatically descends, forming an intelligent feedback system to avoid deformation or damage to parts due to excessive pressure. During the pressing of the planetary gears after meshing, the pressing force is monitored in real time to avoid overload damage. This invention reduces manual intervention and assembly errors through mechanical automation, making it suitable for high-precision assembly scenarios of electromechanical brake calipers (MGU) planetary gear systems.

[0036] like Figure 3 As shown, the planetary gear carrier fixing module includes a lifting mechanism 1 that supports the planetary gear carrier. Above the lifting mechanism 1 is a planetary gear carrier positioning mechanism 2 for circumferentially limiting the planetary gear carrier. The lifting mechanism 1 raises the planetary gear carrier to the working height, while the planetary gear carrier positioning mechanism 2 prevents it from shifting or shaking through the circumferential limiting function, thereby improving the stability of the planetary gear carrier during the assembly process.

[0037] The electromechanical brake caliper MGU planetary gear assembly device also includes a slide loading mechanism 4, on which a planetary gear loading and positioning fixture 3 is mounted. The slide loading mechanism 4 can drive the planetary gear loading and positioning fixture 3 to move. This invention achieves automatic loading and precise positioning of planetary gears through the slide loading mechanism 4 and the planetary gear loading and positioning fixture 3. The slide loading mechanism 4 can quickly transport planetary gears to the assembly station, improving assembly efficiency. The automated loading process reduces human error and ensures the consistency and reliability of the assembly process.

[0038] The three-axis assembly mechanism 5 has three mutually perpendicular axes 53, which can perform translational movements in three-dimensional space along a rectangular coordinate system composed of the X, Y, and Z directions.

[0039] The planetary gear gripper 55 is connected to a lifting and floating spring assembly 57 to enable vertical floating during the meshing process between the planetary gear and the planetary gear carrier ring gear. The lifting and floating spring assembly 57, through its elastic floating design, allows the planetary gear gripper 55 to float slightly up and down during the meshing process. When the photoelectric sensor does not detect a meshing signal, the compression / rebound action of the spring assists the planetary gear gripper in quickly adjusting its position, shortening the debugging time. Furthermore, the lifting and floating spring assembly 57, through flexible adjustment and dynamic buffering, can solve the problem of jamming during rigid alignment in high-precision assembly: when there is a slight misalignment between the teeth, the flexible deformation of the spring can automatically compensate for the positional deviation, avoiding tooth jamming or part damage caused by rigid contact, significantly improving the success rate of tooth alignment. During press-fitting, the lifting and floating spring assembly 57 can absorb the instantaneous impact force caused by assembly path deviations or part size errors, dispersing the pressure through elastic deformation, preventing false alarms or part overload damage caused by a sudden increase in the detection value of the pressure sensor 54, ensuring stable and controllable pressing force.

[0040] The motion drive component 51 is a servo press.

[0041] The assembly method for the MGU planetary gear train of the electromechanical brake caliper includes the following steps:

[0042] S1. Planetary gear carrier fixing module fixes the planetary gear carrier: Lifting mechanism 1 lifts and positions the planetary gear carrier, and planetary gear carrier positioning mechanism 2 limits the planetary gear carrier;

[0043] S2. The planetary gear gripper 55 picks up the planetary gear from the planetary gear loading and positioning fixture 3 and places it above the planetary gear carrier fixing module, driving the planetary gear to rotate and descend simultaneously, and automatically adjusting the assembly path and angle of the planetary gear according to the preset program;

[0044] S3. The planetary gear meshes with the gear ring of the planetary gear carrier. The planetary gear gripper 55 moves up and down, and the photoelectric sensor 56 detects the meshing status of the planetary gear and the gear ring: when the photoelectric sensor 56 does not detect a signal, the planetary gear gripper 55 drives the planetary gear to rise, rotate and fall 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 fall, and the motion drive assembly 51 presses the planetary gear into the planetary gear carrier.

[0045] S4. Pressure sensor 54 monitors pressure in real time. When the detected value is lower or higher than the set value, the system alarms.

[0046] S5. Planetary gear gripper 55 picks up the second planetary gear and inserts it into the planetary gear carrier. Repeat this action until all three planetary gears are inserted into the planetary gear carrier.

[0047] This invention achieves automatic gear engagement between the planetary gears and the planetary gear carrier ring by slowly rotating and lowering the planetary gears via a planetary gear gripper 55. This dynamic assembly method effectively solves the common gear jamming problem in traditional static assembly, significantly improving assembly success rate and efficiency. Through monitoring by photoelectric sensors 56 and pressure sensors 54, real-time data feedback allows the system to dynamically adjust gear engagement and pressing parameters, preventing damage to parts or improper assembly. This ensures the planetary gears are smoothly pressed into the bottom of the planetary gear carrier, avoiding damage or assembly failure due to excessive assembly force, thus improving assembly quality and equipment lifespan. In this invention, the planetary gear gripper 55 sequentially completes the gripping, gear engagement, and pressing of multiple planetary gears according to a preset program. The continuous automated assembly of three planetary gears significantly improves production efficiency and ensures the consistency and reliability of the assembly process.
