Description

Technical Field

[0001] This utility model relates to a snap-fit ​​assembly device, and more particularly to a snap-fit ​​assembly rotary guide mechanism for applications requiring the installation of multiple snap-fits. Background Technology

[0002] When assembling multiple product components or equipment, there is often a need for the assembly of snap-fit ​​parts. Snap-fit ​​assembly is often done manually. However, manual assembly has several problems: firstly, the snap-fits themselves are small, making manual assembly inconvenient; secondly, if many snap-fits need to be assembled on the same product component or equipment, there is a risk of omissions or misalignments, which can increase the overall assembly difficulty. Furthermore, since there may be different positions and angles required for snap-fit ​​assembly, manual assembly cannot always guarantee the correctness of these positions and angles, further complicating the overall assembly of the product component or equipment.

[0003] Patent application number ZL202421044922.8, published on June 11, 2024, discloses a pressing device for assembling automotive metal clips, relating to the field of automotive parts technology. The device includes a base plate, a slide rail fixedly mounted on the top of the base plate, a ring slidably mounted on the slide rail, a mounting plate fixedly connected to the top of the ring, several sets of contoured grooves on the top of the mounting plate, positioning guide posts fixedly connected within the contoured grooves, a driven gear ring fixedly sleeved on the outer edge of the ring, a drive assembly meshing with the driven gear ring on the bottom of the base plate, a mounting bracket fixedly connected to the top of the base plate, an electric telescopic rod fixedly mounted on the inner wall of the mounting bracket, and a mounting plate fixedly connected to the bottom telescopic end of the electric telescopic rod. This device can continuously press-fit clips without requiring manual removal of the pressed clips, thus reducing workload and improving production efficiency. While this solution improves the efficiency of snap-fit ​​assembly, it still cannot effectively meet the actual needs of different assembly positions and angles. Utility Model Content

[0032] Example 1:

[0033] Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5In the illustrated embodiment, a switch sensor 63 and a leak detection cable fixing bracket 65 are installed on the gripper body 60. The switch sensor 63 is used to detect whether the left and right grippers 61 have gripped the clips 62 to be assembled. A leak detection fiber optic cable is fixed on the leak detection cable fixing bracket 65. The switch sensor 63 can be a fiber optic detection probe. When the device is powered on, the fiber optic probe emits infrared light from its fiber optic head. When the left and right grippers 61 grip the clips 62 to be assembled, the clips 62 will block the infrared light, and the fiber optic cable will send a signal indicating that the clips are in place to the control system. Only when all the left and right grippers 61 have gripped the clips 62 can the machine be controlled to operate. If the number of clips is not accurate, the fiber optic cable will not send a signal indicating that the clips are in place to the control system, and the machine will not operate. Everything else is the same as in Embodiment 1.

[0034] The working principle is simple: The gripper component is in standby mode → The gripper component clamps the buckle, with the left and right grippers exerting force on both sides of the buckle → The buckle is installed, and the buckle is in the center position → When the number of buckles is accurately installed, the induction switch is triggered → Press the two power synchronous start switch buttons (green switch) at the same time, and the equipment will start (if the number of buckles is inaccurate, the equipment will not run) → The upper template fixture rotates 90 degrees to align with the product on the lower fixture product seat → The upper and lower fixtures are guided and pressed down vertically → The cylinder stroke controls the height → The buckle is detected and installed on the product → The upper fixture returns to standby mode.
