Its assembly process requires high precision and stability. The spring 72 must be accurately fitted onto the mounting post 711 of the button 71, and its elastic performance must be tested. Finally, the button spring assembly is pressed into the main housing 73 to form a reliable snap-fit.

[0003] Traditional assembly methods generally rely on manual operation, which suffers from low efficiency, poor consistency, and easy omissions in inspection, making it difficult to meet the high-volume, high-reliability production requirements of modern automotive parts. Manual operation is not only labor-intensive, but also lacks stable and effective testing and control of key quality indicators such as spring elasticity and the degree of pressing, which can easily lead to quality problems such as component jamming, abnormal noise, or functional failure.

[0017] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0018] This application proposes an automated assembly device for headrest locking guide sleeves, mainly used to automatically complete the assembly of automotive headrest locking guide sleeves. This assembly typically consists of a main housing 73, a button 71, and a spring 72 (e.g., ...). Figure 1 As shown), during assembly, the spring 72 needs to be precisely fitted onto the mounting post 711 of the button 71, and its elasticity needs to be tested. Finally, the spring button assembly is accurately pressed into the main housing 73.

[0019] like Figure 2 and 3 As shown, the automated assembly equipment mainly includes a machine base 1, a fixed plate 11, an indexing plate 12, a material loading fixture 2, a first feeding mechanism 3, a testing mechanism 4, an assembly mechanism 5, and a unloading mechanism 6.

[0020] like Figure 2 and 3As shown, the fixed plate 11 is fixed above the machine base 1, and the indexing plate 12 is rotatably disposed below the fixed plate 11. The indexing plate 12 is driven to rotate by a servo motor. Several material-carrying fixtures 2 are evenly spaced along the circumference of the indexing plate 12. The material-carrying fixtures 2 rotate with the indexing plate 12 and pass through the loading station, the inspection station, and the assembly station in sequence.

[0021] like Figure 2 and 3 As shown, the upper surface of the material carrier 2 is provided with a shape-matching fitting groove 21 that matches the shape of the button to be assembled. A pair of elastic clamping components 22 are provided on opposite sides of the fitting groove 21. In a specific embodiment, the elastic clamping components 22 are triangular elastic sheets formed by bending. When the button is grasped and placed into the fitting groove 21 from top to bottom, the sides of the button will press against the inclined surfaces of the elastic clamping components 22, causing them to elastically open outwards. After the button is in place, the elastic clamping components 22 rely on their own rebound force to clamp the opposite sides of the button, preventing displacement or loosening during subsequent rotation or testing of the indexing plate 12.

[0022] like Figure 2-4 As shown, the first feeding mechanism 3 is set at the feeding station and is used to feed the buttons and springs sequentially into the material carrier 2. It includes a button feeding module 31, a spring feeding module 32, and a first material transfer module 33.

[0023] The button feeding module 31 includes a button vibratory feeder and a first feeding conveyor belt connected to it. A vision positioning system is installed above the button vibratory feeder to accurately position the material and provide coordinate feedback. The first feeding conveyor belt transports multiple disordered buttons to the button vibratory feeder. The button vibratory feeder separates the buttons in the feeder through vibration to prevent them from stacking, so that the vision positioning system can capture, identify, and position them for accurate material grabbing and picking.

[0024] The spring feeding module 32 includes a spring vibratory plate and a second feeding conveyor belt connected to it. Its working principle is the same as that of the button feeding module.

[0025] like Figure 2-4 As shown, the first material transfer module 33 is responsible for performing gripping and placement actions. It includes a material gripper 331, a first lifting drive device 332 that drives the material gripper 331 to move vertically, and a first horizontal moving device 333 that drives the first lifting drive device 332 to move along the X and Y axes in the horizontal plane. In a specific embodiment, the first lifting drive device 332 is preferably a synchronous belt lifting module composed of a servo motor, a synchronous belt, and pulleys, wherein the material gripper is fixed to one side of the synchronous belt via a connecting support plate; the first horizontal moving device 333 is preferably an X-axis moving module and a Y-axis moving module. The material gripper is configured to be compatible with both gripping buttons and springs.

[0026] The specific workflow is as follows: First, the first material transfer module 33 moves above the button vibratory feeder. After visual positioning, the material picker 331 picks up a button and moves it above the material carrier fixture 2 at the loading station. The button is then placed into the receiving slot 21, ensuring that the button's mounting post faces away from the center of the indexing plate. Subsequently, the first material transfer module 33 moves above the spring vibratory feeder, picks up a spring, and moves it again above the material carrier fixture 2. The spring is then horizontally fitted onto the button's mounting post, completing the initial assembly.

[0027] like Figure 2-3 As shown, the testing mechanism 4 is set up corresponding to the testing station and is used to test whether the elasticity of the spring is qualified. The testing mechanism 4 includes a positioning and clamping mechanism 41 fixed on the fixed plate 11 and corresponding to the testing station position, and a spring testing module 42 set on the horizontal side of the indexing plate.

[0028] like Figure 2-3 As shown, the positioning and clamping mechanism 41 includes a mounting plate 411, on which a pressing cylinder 412 is vertically mounted. The output end of the pressing cylinder 412 faces downward and is connected to a pressing plate 413. When the indexing plate 12 stops rotating, the pressing cylinder 412 drives the pressing plate 413 to move downward, pressing the button in the loading fixture 2 to keep it stable during subsequent testing and avoid errors.

[0029] like Figure 2-3 As shown, the spring detection module 42 includes a base plate 421, a first lateral movement drive device 423 for driving the base plate 421 to move laterally, a detection channel 422 formed on the base plate 421, and a detection rod 424 movably disposed within the detection channel 422. The detection rod 424 is driven by a second lateral movement drive device 425. The detection channel 422 is aligned with the axis of the mounting post. In a specific embodiment, the first lateral movement drive device 423 and the second lateral movement drive device 425 can be selected from servo cylinders or electric cylinders with precise stroke.

[0030] The specific workflow is as follows: When the button on the pressure plate 413 is pressed, the first transverse drive device 423 drives the entire spring detection module forward, so that the opening of the detection channel 422 completely surrounds the mounting post containing the spring. Subsequently, the second transverse drive device 425 drives the detection rod 424 forward with a preset force and stroke, compressing the spring. The compression amount of the spring is detected by a displacement sensor installed on the upper end of the second transverse drive device 425, and the data is compared with a preset standard value to determine whether the spring elasticity is qualified. After the test is completed, the detection rod retracts, and the entire module retracts.

[0031] like Figure 2As shown, the assembly mechanism 5 is set up corresponding to the assembly station and is used to press-fit qualified button spring assemblies to the main housing. It includes a main housing feeding module 51, a second material transfer module 52, a main housing temporary storage module 53, and an assembly robot 54.

[0032] The main housing feeding module 51 includes a main housing vibratory feeder and a third feeding conveyor belt connected to it. Its working principle is the same as that of the button feeding module.

[0033] The second transfer module 52 has a structure basically the same as the first transfer module 33. It is equipped with a second gripper for holding the main housing and for grasping the main housing from the vibratory feeder. The second transfer module also includes a flipping drive (not shown), with the second gripper connected to the output end of the flipping drive to flip the horizontally held main housing to a vertical position. In a specific embodiment, the flipping drive can be a combination of an electric push rod and a four-bar linkage, or a cylinder and a rack and pinion mechanism.

[0034] like Figure 2 and Figure 5 As shown, the main housing temporary storage module 53 includes a rotary drive 531 and a support frame 532 disposed at the output end of the rotary drive 531. A temporary storage fixture 533 is provided at each end of the support frame 532. The temporary storage fixture 533 has a temporary storage slot for accommodating the main housing, which is contoured to the main housing. A snap-fit ​​step 534 is provided at the top of the temporary storage slot, and the head of the main housing is reliably supported by the snap-fit ​​step 534. Elastic clamping components are disposed on both sides of the temporary storage slot to elastically abut against the sides of the main housing. The rotary drive 531 drives the support frame 532 to rotate 180°, allowing the two sets of temporary storage fixtures to switch between the receiving station and the assembly station. The second picking gripper horizontally pushes the grasped main housing into the temporary storage fixture 533. Subsequently, the support frame 532 rotates 180°, rotating the temporary storage fixture 533 containing the main housing to the assembly station on one side of the assembly robot 54.

[0035] like Figure 2 and Figure 6As shown, the assembly robot 54 includes a first vacuum suction member 541 for adsorbing the button, a second lifting drive device 542 for driving its vertical movement, and a second horizontal moving device 543 for driving its lateral movement. The assembly robot 54 is used to extract the inspected and qualified button spring assembly from the loading fixture 2. The first vacuum suction member 541 descends, suctions the button in the receiving groove 21, then rises and transfers it above the temporary storage fixture 533. Finally, through the cooperation of the second horizontal moving device 543 and the second lifting drive device 542, the mounting post of the button is precisely and horizontally pressed into the corresponding assembly hole of the main housing. The button and the main housing snap together, completing the final assembly. Preferably, in this embodiment, the first vacuum suction member 541 includes a fitting block that conforms to the upper surface of the button and a vacuum nozzle disposed in the fitting block to ensure the stability of the button during the suction and transfer process. In a specific embodiment, the second lifting drive device 542 and the second horizontal moving device 543 can be servo drive modules.

[0036] like Figure 2 and Figure 6 As shown, the assembly mechanism 5 also includes a pressing and stabilizing mechanism 55, which is located above the assembly station of the temporary storage module. It includes a pressure plate 551 and a pressing cylinder 552 that drives the pressure plate 551 to move vertically up and down. When the assembly robot 54 performs the pressing operation, the pressing cylinder 552 extends downward and the pressure plate 551 presses down on the top of the main housing to prevent it from tilting or shifting when subjected to assembly force, thus maintaining stability during the pressing process and achieving precision pressing.

[0037] The unloading mechanism 6 is located on one side of the receiving station of the main housing temporary storage module 53. It includes unloading grippers, a third lifting drive device that drives the unloading grippers to rise and fall, and a third horizontal moving device (not specifically shown) that drives the third lifting drive device to move horizontally. After the component is assembled on the assembly station side, the rotary drive 531 drives the support frame 532 to rotate 180° again; the unloading grippers move to the side of the assembled component, clamp the component, and transfer it to the qualified product bin; the second transfer module 52 continues to load the main housing into the temporary storage fixture 533.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
