[0035] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Figures 1 to 11 The tensioner fully automatic assembly equipment includes a turntable 100, a first workpiece placement seat 101 is arranged on the circumference of the turntable 100, a second workpiece placement seat 102 is arranged on one side of the first workpiece placement seat 101, and a fixed disk 200 is fixed at the center of the turntable 100. The shell loading module 1, the plastic gasket loading module 2, the large spring loading module 3, the screw rod loading module 4, the screw rod assembly assembly module 5, the screw rod assembly installation module 6 and the finished product removal module 7 are sequentially arranged on the circumference of the fixed disk 200.

[0036] The shell loading module 1 is used to transport the shell to the first workpiece placement seat 101, and a shell twisting mechanism 8 is provided below the turntable 100. The shell twisting mechanism 8 includes a plug-in rod 80 that can be inserted into the first workpiece placement seat 101, a plug-in rod driving mechanism 81 that drives the plug-in rod 80 to rotate, and a plug-in rod lifting mechanism 82 that drives the plug-in rod 80 and the plug-in rod driving mechanism 81 to rise and fall simultaneously. The shell twisting mechanism 8 is used to twist the shell placed in the first workpiece placement seat 101 to a preset angle to facilitate the subsequent insertion of plastic sheets. Specifically, the shell loading module 1 includes a shell guide seat 10, on which a through hole 10a for the shell to pass through is provided, the feed end of the through hole is connected to the shell vibrating feeding tray, a movable blocking plate 13 is provided below the through hole, a first clamping portion 11 is provided below the shell guide seat 10 for clamping the shell located at the bottom of the through hole 10a, and a second clamping portion 12 is provided above the shell guide seat 10 for clamping the shell located adjacent to the bottom shell. In the above structure, the first clamping portion 11 and the second clamping portion 12 are provided so that the shell W1 to be blanked and the adjacent shell can be effectively separated. Specifically, when the blocking plate 13 moves away from the through-hole position, the first clamping portion 11 is kept loose and the second clamping portion 12 is kept clamped, so that only one shell is dropped at a time without causing the adjacent shells to overlap.

[0037] The plastic gasket loading module 2 is used to feed the plastic gasket W2 into the positioning step inside the shell through a plastic gasket gripper mechanism; specifically, the plastic gasket loading module 2 includes a plastic gasket vibrating disk 20, a plastic gasket placement seat 21 arranged at the tail end of the conveying guide rail of the plastic gasket vibrating disk 20, and a plastic gasket gripper mechanism 22 for grabbing the plastic gasket in the plastic gasket placement seat 21 is provided on the plastic gasket placement seat 21, and the plastic gasket gripper mechanism 22 includes a grabbing rod 23, a positioning step 24 is provided at the tail end of the grabbing rod, and a negative pressure hole 25 is provided at the positioning step. When grabbing the material of the plastic gasket placement seat 21, the grabbing rod 23 first descends so that the plastic gasket is pressed against the positioning step of the grabbing rod. At this time, the negative pressure generated by the negative pressure hole 25 adsorbs the plastic gasket on the grabbing rod 23. When installing the plastic gasket,

[0038] The grab bar 23 is inserted into the housing within the first workpiece placement seat 101. The negative pressure is then turned off, and the plastic gasket automatically falls into the housing, completing installation. A movable stopper mechanism 26 is provided between the tail end of the conveyor rail and the plastic gasket placement seat 21. The stopper mechanism 26 includes a plastic gasket through-hole 300 for the plastic gasket to pass through. The stopper mechanism 26 controls the delivery of the plastic gaskets, ensuring that one piece is delivered at a time.
