DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but is not intended to be limiting of the present invention. Any structure or process not specifically noted is conventional prior art in the art.

[0021] Embodiment 1. An automatic detection and sorting device for automobile lock cylinder components includes a mounting frame 1, a defective product box 11 and a good product chute 12 are provided on the side of the mounting frame 1, a sliding part is installed on the mounting frame 1, a finger cylinder 8 and a detection component 9 are installed on the sliding part, and a clamping claw 10 is installed on the finger cylinder 8.

[0022] like Figure 3-6 As shown, the detection component 9 includes a fixed frame 15, a proximity switch frame 19 is installed on the fixed frame 15, a proximity switch 16 and a proximity switch 21 are installed on the proximity switch frame 19, a movable shutter detection top block 13 and a movable baffle detection top block 14 are installed at the center of the fixed frame 15, a counterweight block 25 is installed on the shutter detection block 13, a detection round pin 24 is installed on the counterweight block 25, a small spring 20 and a proximity switch frame 1 22 and a sensing block bracket 17 are installed on the baffle detection block, a proximity switch 3 23 is installed on the proximity switch frame 1 22, and a sensing block 18 is installed on the sensing block bracket 17.

[0023] The detection component 9 is used to detect the lock core component. Figure 7-9 As shown, the lock core assembly includes a lock core 26, on which a torsion spring 29, a baffle 28 and a baffle 27 are provided; the torsion spring 29 is installed in the corresponding torsion spring mounting groove 31 on the lock core 26, and the feet extending at both ends of the baffle 28 are also installed in the baffle mounting groove 30 corresponding to the lock core 26, one side of the supporting foot of the torsion spring 29 is stuck in the lock core groove, and the other side is against the baffle 28. After the baffle 27 is installed, it can ensure that the torsion spring 29 and the baffle 28 will not fall off.

[0024] The detection component 9 is used to detect whether the lock core component is qualified and sort it. When there is a lack of lock core, lack of torsion spring, lack of baffle, lack of baffle and excessive deformation of baffle, it is considered unqualified. When the detection component 9 is under natural conditions, the proximity switch 16 is triggered, the proximity switch 2 21 is just not triggered when detecting qualified parts, and the proximity switch 3 23 is not triggered. The qualified detection conditions are: the proximity switch 1 16 is not triggered, the proximity switch 2 21 is not triggered, and the proximity switch 3 23 is triggered. The detection component 9 can be divided into three parts according to relative activity. The first part has a fixed frame 15, a proximity switch 1 16, a proximity switch frame 19, and a proximity switch 2 21; the second part has a baffle detection top block 14, a sensing bracket 17, a sensing block 18, a small spring 20, a proximity switch frame 1 22, and a proximity switch 3 23; the third part has a movable baffle detection top block 13, a detection round pin 24 and a counterweight 25. Among them, the first part is relatively fixed, and the second and third parts can move up and down. In the second part, the baffle detection top block 14 is installed with an induction bracket 17, and the induction bracket 17 is installed with an induction block 18, a small spring 20 and a proximity switch frame 1 22, and the proximity switch frame 1 22 is installed with a proximity switch 3 23. When detecting the lock core assembly, if it is qualified, the third part is lifted up, and the proximity switch 1 16 and the proximity switch 2 21 are not triggered. In the natural state, the proximity switch 1 16 is triggered, and the proximity switch 2 21 is just not triggered when detecting the qualified parts. When the detection component 9 detects the lock core assembly, the second part and the third part are detected at the same time. In the third part, the movable shutter detection top block 13 is fixed with a counterweight block 25, and the counterweight block 25 is fixed with a detection round pin 24. When detecting the lock core assembly, if it is qualified, the movable shutter detection top block 13, the counterweight block 25, and the detection round pin 24 are lifted up by the shutter, triggering the proximity switch 3 23.

[0025] The sliding part includes a guide rail slider 2, on which a connecting block 3 and a connecting plate 5 are installed. The connecting block 3 is connected to one end of a double-rod double-position cylinder 4, and the other end of the double-rod double-position cylinder 4 is fixed on a mounting frame 1. A lifting cylinder 6 with a limiting screw is installed on the connecting plate 5, and a connecting plate 2 7 is installed on the lifting cylinder 6.

[0026] The gravity of the counterweight 25 is smaller than the torsion spring resilience of the lock core assembly.

[0027] When in use, the lock core 26 after assembling the torsion spring 29, the baffle plate 28 and the baffle plate 27 in sequence is provided with, and is transmitted to the specified position by the lock core clamp, the lifting cylinder 6 drives the detection assembly 9 to move downward to the limit position, the finger cylinder 8 closes and drives the clamping claw 10 to clamp the lock core assembly. At the same time, the detection assembly 9 detects the lock core assembly and draws a conclusion, and then the lifting cylinder 6 is reset, and the lock core assembly is clamped by the clamping claw 10 and rises together. After reaching the specified position, the double-rod double-stroke cylinder 4 acts. If the detection result of the lock core assembly by the detection assembly 9 is qualified, the two directions of the double-rod double-position cylinder 4 move at the same time, and the lock core assembly is sent to the top of the good product chute 12, the finger cylinder 8 is reset, driving the clamping claw 10 to loosen the lock core, and the lock core falls into the good product chute 12 to enter the next process. If the detection result is unqualified, the double-rod double-position cylinder 4 only moves in one direction, and the lock core assembly is sent to the top of the defective product box 11, the clamping claw is loosened, and the lock core assembly falls into the defective product box 11.
