[0018] The present invention will be further described below with reference to specific embodiments.
[0019] Refer to the instruction manual appendix Figures 1 to 6A yarn feeder's yarn guide bar clamp screw assembly device includes an equipment cabinet 1. The equipment cabinet 1 is characterized by having a rotating assembly for switching workstations, a locking assembly for positioning the yarn guide bar clamp, a fixing plate 4 installed at each of the two workstations, a guide platform 5 installed on the fixing plate 4, a positioning assembly for positioning the screw and the yarn guide bar clamp at the position corresponding to the guide platform 5, a feeding mechanism at each of the multiple workstations, and a lifting mechanism at the position corresponding to the remaining workstation, with a screw-making machine 9 mounted on the lifting mechanism.
[0020] It should be noted that, through the multi-station cycle function of the rotating component, the clamping component holding the workpiece is sequentially transferred to the feeding station, the positioning station, and the screw-tightening station. Under the coordination of the control system, each component works in an orderly and collaborative manner, realizing the full automation of the yarn guide bar clamp screw assembly process, including key steps such as workpiece transfer, precise positioning, and screw tightening. This completely eliminates the bottlenecks and errors of manual operation, greatly improves assembly efficiency and consistency, and significantly reduces labor costs and labor intensity.
[0021] Refer to the instruction manual appendix Figure 1 and Figure 2 The rotating assembly includes a servo motor 21 fixed on the equipment cabinet 1, a reducer 22 installed at the output end of the servo motor 21, a flange joint 23 installed at the output end of the reducer 22, and a turntable 24 fixed on the flange joint 23. The servo motor 21 is used to drive the turntable 24 to rotate.
[0022] It should be noted that the servo motor 21, as the core power source, drives the flange joint 23 and the turntable 24 to perform precise rotation indexing by matching the output speed and torque through the reducer 22. This design enables automatic cyclic switching of multiple assembly stations (such as feeding, positioning, and screwing stations).
[0023] Refer to the instruction manual appendix Figure 2 and Figure 3 The locking assembly includes multiple fixed seats 31 fixed on the turntable 24, a locking seat 32 mounted on the fixed seats 31, a long shaft 33 fixed on the locking seat 32, and a short shaft 34 assembled on the locking seat 32 by a spring. The multiple fixed seats 31 are distributed circumferentially around the center of the turntable 24. The long shaft 33 is used to position the yarn guide bar clamp, and the short shaft 34 is used to position the nut.
[0024] It should be noted that the card holder 32, as the core carrier, has a long shaft 33 fixed on it, which is specifically used to precisely define the position of the yarn guide bar clamp to ensure its stability. The short shaft 34, which is assembled by a spring, uses its elastic force to adaptively position the nut, ensuring the accuracy and consistency of subsequent assembly steps.
[0025] Refer to the instruction manual appendix Figure 1 and Figure 4 The positioning assembly includes two mounting bases 61 fixed on the equipment cabinet 1, a mounting bracket 62 fixed on the mounting base 61, a support plate 65 fixed on the top of the mounting bracket 62, a positioning groove 66 opened on the support plate 65, a mounting plate 63 fixed on one of the mounting brackets 62, and a first cylinder 64 fixed on the mounting plate 63. The two positioning grooves 66 are used to position the nut and the yarn guide clamp, respectively, and the first cylinder 64 is used to lift the nut.
[0026] It should be noted that the precisely cut positioning groove 66 on the support plate 65 provides a positioning reference for the screw and the yarn guide clamp. After the external vibrating feeder feeds the nut into the corresponding positioning groove 66 through the guide table 5, the first cylinder 64 is activated, and its output end lifts the nut in the positioning groove 66, which facilitates the subsequent clamping and conveying of the nut.
[0027] Refer to the instruction manual appendix Figure 1 and Figure 5 The feeding mechanism includes a transverse component mounted on the equipment cabinet 1 and a longitudinal component mounted on the transverse component. The transverse component is used to drive the longitudinal component to move laterally, and the longitudinal component clamps the parts and drives the parts to rise and fall.
[0028] It should be noted that the feeding mechanism consists of a transverse component and a longitudinal component working together. The transverse component is responsible for driving the entire longitudinal component to move a wide range of positions in the horizontal plane, transporting the workpiece from the feeding area to the assembly station, while the longitudinal component is responsible for performing lifting and lowering actions in the vertical direction.
[0029] Refer to the instruction manual appendix Figure 1 and Figure 5 The transverse component includes a bracket 71 fixed on the equipment cabinet 1, a first guide rail 72 fixed on the bracket 71, a second cylinder 73 fixed on the first guide rail 72, and a second guide rail 74 fixed on the output end of the second cylinder 73. The second guide rail 74 is slidably connected to the first guide rail 72, and the second cylinder 73 is used to drive the second guide rail 74 to move.
[0030] It should be noted that the second cylinder 73, as the driving source, directly pushes the second guide rail 74 to slide along the direction defined by the first guide rail 72 when it extends or retracts.
[0031] Refer to the instruction manual appendix Figure 1 and Figure 5 The longitudinal movement assembly includes a third cylinder 75 fixed on the second guide rail 74, a slide 76 fixed on the output end of the third cylinder 75, and a pneumatic gripper 77 mounted on the slide 76. The slide 76 is slidably connected to the second guide rail 74, and the third cylinder 75 is used to drive the slide 76 to move.
[0032] It should be noted that the third cylinder 75 serves as the power source, and the extension and retraction of its piston rod drives the slide 76 to perform precise lifting and lowering movements along the vertical direction defined by the second guide rail 74. The pneumatic gripper 77 fixed on the slide 76 performs clamping or releasing actions on the workpiece according to the command.
[0033] Refer to the instruction manual appendix Figure 1 and Figure 6 The lifting mechanism includes a drive assembly mounted on the equipment cabinet 1 and an adjustment assembly mounted on the drive assembly. The drive assembly is used to drive the screw machine 9 to lift and lower, and the adjustment assembly is used to adjust the initial height of the screw machine 9.
[0034] It should be noted that the drive assembly provides the main vertical driving force to drive the screwdriver 9 to complete the screw-in action, while the main function of the pitch adjustment assembly is to finely adjust the initial installation height of the screwdriver 9 when the equipment is initially set up or when the product model is changed.
[0035] Refer to the instruction manual appendix Figure 1 and Figure 6 The drive assembly includes a fixed frame 81 fixed on the equipment cabinet 1, a fourth cylinder 82 mounted on the fixed frame 81, and a first movable seat 83 fixed to the output end of the fourth cylinder 82. The first movable seat 83 is slidably connected to the fixed frame 81, and the fourth cylinder 82 is used to drive the first movable seat 83 to move.
[0036] It should be noted that the fourth cylinder 82, as the core actuator, directly drives the first moving seat 83 to perform precise vertical lifting and lowering movements along the guide structure on the fixed frame 81 through the extension and retraction of its piston rod. This ensures that the screwdriver head can press vertically and tighten the screw with the set force and speed, making it the core power transmission unit for completing the screw assembly action.
[0037] Refer to the instruction manual appendix Figure 1 and Figure 6 The adjustable distance assembly includes a second movable seat 84 slidably connected to a fixed frame 81, a connecting rod 85 rotatably connected to the second movable seat 84, and a drive motor 86 mounted on a first movable seat 83. The connecting rod 85 is threadedly connected to the first movable seat 83, and the output end of the drive motor 86 is connected to the screw machine 9.
[0038] It should be noted that, since the connecting rod 85 and the first movable seat 83 are connected by a thread, the rotational motion of the connecting rod 85 is converted into its own axial displacement relative to the first movable seat 83. Since the second movable seat 84 is slidably connected to the fixed frame 81 and rotatably connected to the connecting rod 85, the axial movement of the connecting rod 85 will force the second movable seat 84 to undergo vertical displacement relative to the fixed frame 81, thus finely adjusting the initial installation height reference position of the screw machine 9 as a whole, thereby accurately matching the assembly height requirements of different workpieces.
[0039] Working principle: Servo motor 21 drives turntable 24 to rotate precisely through reducer 22 and flange joint 23, which sequentially moves the clamps 32, which are fixed on multiple fixed seats 31 on turntable 24, to different work stations. The long shaft 33 on clamp 32 is used to position the yarn guide bar clamp, and the short shaft 34 is used to position the nut. The parts are conveyed by an external vibrating feeder. At the feeding station, the first guide rail 72 and the second cylinder 73 on bracket 71 drive the second guide rail 74 to move laterally. The third cylinder 75 on the second guide rail 74 drives the slide 76 to rise and fall. The pneumatic gripper 77 on the slide 76 grips the screw. Or the yarn guide bar clamp is moved to the corresponding card holder 32. At the screw-driving station, the fourth cylinder 82 on the fixed frame 81 drives the first moving seat 83 to rise and fall vertically. The drive motor 86 on the first moving seat 83 drives the screw machine 9 to tighten the screw. After assembly, the feeding mechanism clamps and moves the screw to the unloading frame. The whole device is controlled by the PLC to control the main circuit. The intermediate relay, AC contactor, circuit breaker, router and sensor in the circuit output or input different signals to the PLC so that when the part or pneumatic gripper 77 of each station is in place, the next action can be performed.
[0040] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Therefore, this utility model will not explain the control method and circuit connection in detail. In this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
