Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a main fixture front-to-back movement component. Background Technology

[0002] In the field of automation equipment technology, particularly in the riveting and height detection processes of automotive left and right switch handle bodies and their flexible printed circuit boards (FPCs), existing main fixture moving components mostly employ manual operation or simple linear movement mechanisms, failing to achieve efficient automated transfer, multi-directional rotation adjustment, and precise position feedback. This results in low production efficiency, insufficient operational accuracy, large riveting and detection errors, and difficulty in supporting continuous processing of multiple end faces (front, left, and right). Furthermore, existing components lack integrated servo rotation and buffer protection mechanisms, making them prone to vibration or positional deviations during rotation, affecting the consistency of riveting height and product quality. In addition, existing technologies lack auxiliary devices such as vacuum adsorption and photoelectric sensing, failing to ensure the stability and reliability of components under high-intensity production environments, increasing manual intervention, manufacturing costs, and equipment space requirements.

[0019] Reference Figures 1 to 5 This utility model provides a main fixture front-to-back movement assembly, which includes a first front-to-back movement module 11, a servo rotation assembly 12 disposed at the output end of the first front-to-back movement module 11, and a main fixture 13; the output end of the servo rotation assembly 12 is connected to the main fixture 13 and is used to drive the main fixture 13 to rotate. In this embodiment, the working principle of the main fixture forward and backward moving assembly 1 is as follows: During riveting, the first forward and backward moving module 11 is driven to move the servo rotating assembly 12 and the main fixture 13 to the riveting position, allowing the front hot riveting assembly 2, the left end hot riveting assembly 3, and the right end hot riveting assembly 4 to perform riveting on the front, left, and right ends; when height detection is required, the first forward and backward moving module 11 is further driven to move the servo rotating assembly 12 and the main fixture 13 to the height detection position, allowing the external riveting point height detection assembly to perform height detection. First, the rivet height of the rivet on the front of the main body is detected. Next, the main body fixture 13 can be driven to rotate 90° clockwise by the servo rotation component 12, causing the handle body and FPC on the main body fixture 13 to rotate 90° clockwise. The rivet height of the rivet on the left end face of the handle body and FPC is detected. Then, the main body fixture 13 is driven to rotate 180° counterclockwise to detect the rivet height of the rivet on the right end face of the handle body and FPC. After the detection is completed, the main body fixture 13 can be driven to rotate 90° clockwise to return to the center position, and then exit to the loading and unloading position for manual product handling.

[0020] The main fixture forward and backward moving component 1, through the integrated design of the first forward and backward moving module 11, the servo rotating component 12, and the main fixture 13, realizes automated transmission and orientation adjustment of the handle body and FPC during riveting and height detection processes. Specifically, the first forward and backward moving module 11 drives the servo rotating component 12 and the main fixture 13 to move in the forward and backward direction, sequentially transporting the handle body and FPC to the riveting position and height detection position, supporting multi-directional riveting operations of the front hot riveting component 2, the left end hot riveting component 3, and the right end hot riveting component 4 on the FPC. The output end of the servo rotating component 12 is connected to the main fixture 13, which can precisely drive the main fixture 13 to rotate clockwise or counterclockwise (such as 90° or 180°), thereby adjusting the posture of the handle body and FPC, and realizing the individual detection of the riveting point height on the front, left end, and right end faces. After the detection is completed, it is rotated back to the center and exits to the loading and unloading position, facilitating manual product handling and ensuring the continuity and efficiency of the entire riveting and detection process. Through the coordinated drive of the first forward and backward moving module and the servo rotating component, seamless transfer and rotation of the handle body and FPC are achieved, reducing manual operation and improving the automation level and overall processing speed of the production line. The servo rotating component 12 provides high-precision rotation functions (such as 90° clockwise and 180° counterclockwise) to ensure accurate orientation detection of rivet points on different end faces of the handle body at the height detection position, avoiding detection errors caused by positional deviations. It supports rapid switching between the riveting position and the height detection position, as well as sequential processing of multiple end faces (front, left, and right), achieving multi-purpose functionality and reducing equipment space occupation and manufacturing costs. Through precise movement and rotation mechanisms, comprehensive coverage of riveting and detection is ensured, improving the consistency and reliability of FPC rivet point height, and ultimately enhancing the overall quality and pass rate of automotive left and right switch products.

[0021] Furthermore, the servo rotation assembly 12 includes a fixed base plate 119, two side-by-side fixed seats 120 and 128 on the fixed base plate 119, a servo motor 121 on the fixed seat 120, a coupling 122 at the output end of the servo motor 121, an active rotating shaft connected to the coupling 122, a rotating block 125 mounted on the end of the active rotating shaft, a fixed block 126 fixed to the rotating block 125, a buffer 127 arranged on both sides of the rotating block 125, a driven rotating shaft on the fixed seat 128, a rotating block 131 at one end of the driven rotating shaft, a fixed block 132 fixed to the rotating block 131 and opposite to the fixed block 126, a buffer 134 at both ends of the rotating block 131, a photoelectric switch 135 on the fixed seat 128, and a photoelectric switch sensor 136 at the other end of the driven rotating shaft and adapted to the photoelectric switch 135. Furthermore, the active rotating shaft is provided with a bearing seat 124 and a locking nut 123. The active rotating shaft is mounted on the fixed seat 120 via the bearing seat 124, and the locking nut 123 is located at the rear end of the bearing seat 124. The driven rotating shaft is provided with a bearing seat 129 and a locking nut 130. The driven rotating shaft is mounted on the fixed seat 128 via the bearing seat 129, and the locking nut 130 is located at the rear end of the bearing seat 129. The fixing block 126 and the fixing block 132 are both provided with slots for engaging with the main fixture 13. In this embodiment, the working principle of the servo rotation component 12 is as follows: the servo motor 121 drives the active rotating shaft to rotate, thereby causing the rotating block 125 and its fixed block 126 to move, which in turn causes the main fixture 13 mounted on the fixed block 126 and the fixed block 132 to rotate. Specifically, the servo motor 121 drives the active rotating shaft connected by the shaft coupling 122 to rotate, thereby causing the rotating block 125 and the fixed block 126 to move. At the same time, through the linkage of the driven rotating shaft, the rotating block 131 and the fixed block 132, the synchronous rotation of the main fixture 13 is achieved. Bearing housing 124, anti-loosening nut 123, bearing housing 130, and anti-loosening nut 129 ensure stable installation and anti-loosening fixation of the driving and driven shafts; the slots on fixing block 126 and fixing block 132 are used for snap-fit ​​connection with the main fixture 13; buffer 127 and buffer 134 are arranged on both sides of the rotating blocks (rotating block 125 and rotating block 131) to provide buffer protection during rotation; photoelectric switch 135 and photoelectric switch sensor 136 are used to monitor the position of the driven shaft to ensure accurate feedback and control of the rotation angle. This assembly is used to drive the main fixture 13 to rotate clockwise or counterclockwise (e.g., 90° or 180°), ensuring accurate orientation adjustment of the main fixture 13 and avoiding positional deviations from affecting riveting and inspection quality.

[0022] Furthermore, the first forward and backward moving module 11 is also equipped with a photoelectric sensor 111, and the corresponding fixed base plate 119 is equipped with a photoelectric sensing sheet 112 adapted to the photoelectric sensor 111. The first forward and backward moving module 11 includes a first Y-axis linear module; the first forward and backward moving module 11 adopts a first Y-axis linear module to realize linear drive along the Y-axis direction, driving the servo rotating component 12 and the main fixture 13 to smoothly transfer between the riveting position, the height detection position, and the loading and unloading position, supporting the continuous operation of the entire automated process. The cooperation of the photoelectric sensor 111 and the photoelectric sensing sheet 112 realizes real-time sensing and feedback of the position of the first forward and backward moving module 11, avoids motion errors, and ensures accurate switching of the component between the riveting position and the height detection position.

[0023] Furthermore, the main fixture 13 includes a connecting plate 13a, a placement platform 13b mounted on the connecting plate 13a, and spherical buckles 13c arranged on the connecting plate 13a and on both sides of the placement platform 13b. The placement platform 13b has mounting slots for placing the handle body and its FPC. The connecting plate 13a serves as a base support, with the placement platform 13b mounted and the spherical buckles 13c arranged on both sides. The mounting slots in the placement platform 13b precisely match the shape of the handle body and its FPC, ensuring accurate positioning during riveting and testing. The side of the fixed base 120 is also equipped with a negative pressure gauge 66, a vacuum generator 77, and a solenoid valve 88.
