Description

Technical Field

[0001] This invention relates to the field of automated assembly technology, specifically to an automated assembly device and method for seat belt buckles. Background Technology

[0002] The seat belt buckle is an important device in a car seat belt. Its main function is to lock the buckle when the passenger inserts the latch into the buckle by a certain displacement, at which point the passenger can wear the seat belt normally.

[0003] For example, Chinese patent CN218245982U discloses a small car seat belt buckle assembly, including a lock body, slider, buckle plate, spring, pin, button and other accessories. Due to the large number of accessories in the seat belt buckle, the assembly process is complicated. Currently, the assembly of seat belt buckles is carried out by semi-automatic assembly or manual assembly, which has the problems of high production cost, low efficiency and poor product consistency.

[0004] In view of this, there is an urgent need to design an automated assembly equipment for seat belt buckles to overcome the problems of assembly efficiency and product consistency of existing seat belt buckles. Summary of the Invention

[0005] To address the above problems, this invention provides an automated assembly device and method for seat belt buckles.

[0006] In a first aspect of the invention, an automated assembly device for seat belt buckles is provided, comprising a tooling circulation mechanism and an assembly fixture connected to the tooling circulation mechanism. The assembly fixture is driven by the tooling circulation mechanism to sequentially pass through a lock body feeding mechanism, a slider assembly mechanism, a buckle assembly mechanism, a spring assembly mechanism, a pin assembly mechanism, a tensioning and shaping mechanism, a button assembly mechanism, a buckle locking detection mechanism, and a product unloading mechanism. The assembly fixture is provided with a tooling positioning structure. The lock body feeding mechanism installs the lock body onto the assembly fixture, and the slider assembly mechanism installs the slider... The fastener assembly mechanism installs the fasteners onto the assembly fixture, the spring assembly mechanism installs the springs onto the assembly fixture, the pin assembly mechanism installs the pins onto the assembly fixture, the tensioning and shaping mechanism tensions and shapes the parts on the assembly fixture, the button assembly mechanism installs the buttons onto the assembly fixture, the buckle locking detection mechanism performs insertion locking detection and press-pull-out detection on the assembled seat belt buckles on the assembly fixture, and the product unloading mechanism screens and unloads the detected seat belt buckles.

[0007] In a second aspect of the present invention, an automated assembly method for seat belt buckles is provided, comprising assembling seat belt buckles on assembly fixtures using the aforementioned automated seat belt buckle assembly equipment, comprising the following steps: The lock body is fed into the assembly table. The lock body feeding horizontal movement force source, the lock body feeding vertical movement force source and the lock body clamping power source are combined to control the lock body clamping claws to grab the lock body on the lock body feeding table and put it onto the assembly fixture. After the lock body feeding is completed, the lock body position detection component performs installation position detection on the lock body on the assembly fixture. The slider feeding process involves a combination of actions between the slider vibratory feeder and the slider pushing power source to deliver the slider to the slider feeding position. The slider feeding lateral movement power source, the slider vertical rotation power source, the slider feeding vertical movement power source, the slider horizontal rotation plate, and the slider clamping power source work together to control the slider clamping claws to install the slider on the slider feeding position onto the lock body at a specified angle. The slider position detection component detects the slider on the assembly fixture to ensure it is installed in place. The buckle feeding process involves a combination of a buckle vibratory feeder and a buckle feeding rotary power source to deliver the buckle to the buckle feeding position. A combination of a buckle shaping horizontal movement power source and a buckle shaping vertical movement power source controls the buckle shaping insert to press against the slider on the assembly fixture. A combination of a buckle feeding horizontal movement power source, a buckle feeding vertical movement power source, and a buckle clamping power source controls the buckle clamping claws to transfer the buckle from the buckle feeding position to a designated position on the lock body. A buckle feeding air blowing power source controls the buckle blowing pipe to blow air onto the buckle, allowing the buckle to be installed onto the lock body. A buckle position detection component detects the buckle's proper installation position on the assembly fixture. The spring feeding process involves a combination of a spring vibratory feeder and a spring feeding flipping power source to deliver the spring to the spring feeding position. A combination of a spring positioning vertical movement power source and a first spring positioning horizontal movement power source controls the spring positioning hook plate to pull the slider to the spring assembly position. A second spring positioning horizontal movement power source controls the spring positioning insert plate to push the slider to the spring assembly angle. A combination of a spring feeding horizontal movement power source, a spring feeding rotation power source, a spring feeding extension power source, and a spring clamping power source controls the spring clamping claws to transfer the spring from the spring feeding position to the assembly fixture, abutting one end of the spring against the fastener. A combination of a spring pressing vertical movement power source and a spring pressing assembly power source abuts the other end of the spring against the slider. The spring position detection component detects the spring's proper installation position on the assembly fixture. The pin feeding mechanism combines the action of the pin vibratory feeder and the pin pushing power source to send the pin to the pin feeding position. The pin positioning power source then activates to control the pin positioning plate to press against the slider on the assembly fixture. The pin feeding horizontal movement power source, the pin feeding vertical movement power source, the pin insertion power source, and the pin clamping power source then combine to control the pin clamping claws to remove the pin from the pin feeding position and insert it into the lock body and the slider. The upper tension shaping and upper tension pressing power source action controls the upper tension pressing plate to press the slider on the assembly fixture to the upper tension preparation position, and the upper tension pushing power source action controls the upper tension pushing plate to push the slider on the assembly fixture to the upper tension assembly position. The button feeding process involves a combination of the button vibratory feeder and the button pushing force source to deliver the button to the button feeding position. The button feeding horizontal moving force source, the button feeding vertical moving force source, the button feeding rotational power source, and the button clamping power source work together to control the button clamping claws to transfer the button to the lock body of the assembly fixture. The button pushing power source operates to control the button pushing component to push the buckle, thereby assembling the button onto the lock body and forming a linkage with the slider. The button position detection component detects the button on the assembly fixture to ensure it is installed in place. The latch locking test involves activating the latch locking power source to insert the latch locking insert into the lock body on the assembly fixture. The latch locking power source then activates again to test whether the latch locking insert can be pulled out of the lock body. The latch unlocking power source activates to press the button on the assembly fixture with the latch unlocking plate to unlock the lock body. The latch locking power source then activates again to pull the latch locking insert out of the lock body. The product unloading mechanism sorts the latches on the assembly fixture based on the detection results fed back by the lock body position detection component, slider position detection component, latch plate position detection component, spring position detection component, button position detection component, and the latch locking detection result.

[0008] Compared with the prior art, the technical solution provided by this invention has the following advantages: This technical solution's automated assembly equipment for seatbelt buckles utilizes a tooling circulation mechanism to achieve continuous operation, significantly reducing manual intervention, increasing assembly speed, and thus substantially reducing production time and improving overall production efficiency. The automated equipment can precisely assemble according to preset programs and parameters, avoiding errors and inconsistencies that may occur during manual assembly. It is also equipped with a buckle locking detection mechanism for quality control, thereby improving product quality and consistency. Furthermore, the modular design allows for easy adjustment of the parameters and processes of each assembly mechanism to adapt to the production needs of different models or specifications of seatbelt buckles, enhancing production flexibility and adaptability.

[0045] Example 2

[0046] Combined with appendix Figure 1 To be continued Figure 13 The present invention provides an automated assembly method for seat belt buckles, which uses the aforementioned automated seat belt buckle assembly equipment to assemble seat belt buckles on assembly fixtures, comprising the following steps: Lock body a is loaded. The horizontal movement force source 23, the vertical movement force source 25, and the clamping power source 27 of the lock body loading are combined to control the lock body clamping claw 28 to grab the lock body on the lock body loading table 21 and put it onto the assembly fixture 11. After the lock body loading is completed, the lock body position detection component 29 performs installation position detection on the lock body on the assembly fixture 11. When slider b is fed, the combined action of slider vibratory plate 31 and slider pushing power source 33 sends slider b to slider loading position 316.

The buckle c shaping horizontal movement power source 415 and the buckle c shaping vertical movement power source 417 work together to control the buckle c shaping insert 419 to press against the slider b on the assembly fixture 11. The buckle c feeding horizontal movement power source 46, the buckle c feeding vertical movement power source 48 and the buckle c clamping power source 410 work together to control the buckle c clamping claw 411 to transfer the buckle c from the buckle c feeding position 420 to the designated position of the lock body a. The buckle c feeding air blowing power source 412 controls the buckle c blowing pipe 413 to blow air onto the buckle c, so that the buckle c is installed on the lock body a. The buckle c position detection component 421 detects the buckle c on the assembly fixture 11 to ensure that it is installed in place. Spring d is fed, and the combined action of spring vibratory plate 51 and spring feeding flipping power source 53 sends spring d to spring feeding position 527. Spring positioning vertical movement power source 56 and spring positioning first horizontal movement power source 58 combine to control spring positioning hook plate 510 to pull slider to spring assembly position.
