DETAILED DESCRIPTION

[0027] The technical scheme of the present application is further described below, but the scope of protection is not limited to the description.

[0028] As Figures 1 to 5 shown.

[0029] The drum bottom detection device of the welding lug electrolytic capacitor testing machine comprises:

[0030] The air cylinder mounting seat 17 is L-shaped and is used for fixedly mounting to the welding lug electrolytic capacitor testing machine; the vertically-lifting air cylinder 2 is vertically mounted on the air cylinder mounting seat 17, and the air cylinder 2 shell is fixed on the air cylinder mounting seat 17; the speed regulating valve 1 is correspondingly mounted on the air cylinder 2 inlet and outlet, the air cylinder 2 air inlet and air outlet displacement is controlled through the speed regulating valve 1, so as to control the vertical extension and retraction of the air cylinder 2. The air cylinder 2 vertically lifts with the detection top rod mounting seat 7.

[0031] The connecting bolt 15 is connected to the bottom of the air cylinder 2 telescopic rod through the nut A16, the nut B14 is screwed on the bottom of the connecting bolt 15, and the nut B14 has a recess inside to accommodate the compression spring 13.

[0032] The detection top rod mounting seat 7 is screwed and fixed on the nut B14, a through hole is vertically arranged in the middle of the detection top rod mounting seat 7, and the compression spring 13 penetrates downward from the through hole; the detection top rod mounting seat 7 is horizontally transversely provided with an action groove.

[0033] The detection top rod mounting seat 7 on the side corresponding to the action groove is fixedly provided with the detection sheet mounting seat 11 through the screw A8, the detection sheet 12 is rotatably connected to the detection sheet mounting seat 11 through the shaft rod 9 and the nut C10, the end of the detection sheet 12 is rotatably mounted on the detection sheet mounting seat 11, the detection sheet 12 swings in the action groove of the detection top rod mounting seat 7 with the detection sheet mounting seat 11 as the support, and the compression spring 13 corresponds to the middle of the detection sheet 12.

[0034] The detection top rod mounting seat 7 on the other side corresponding to the action groove is fixedly provided with the photoelectric mounting base 5 through the bolt, and the photoelectric sensor 4 is fixedly mounted on the photoelectric mounting base 5 through the screw C3. When the detection sheet 12 swings upward with the detection sheet mounting seat 11, the photoelectric sensor 4 converts the displacement signal into an electric signal and transmits it to the PLC control system.

[0035] The detection top rod 6 is installed below the middle of the detection sheet 12 corresponding to the compression spring 13, and the detection top rod 6 can slide and lift in the vertical through hole in the middle of the detection top rod mounting seat 7; the compression spring 13 is correspondingly pressed on the middle of the detection sheet 12 through the gasket and the positioning protrusion.

[0036] When the bottom of the capacitor 18 has an upward drum bottom 19, the drum bottom 19 pushes the detection top rod 6 to vertically displace, the detection top rod 6 pushes the detection sheet 12 to rotate against the elastic force of the compression spring 13, when the detection sheet 12 rotates and swings upwardly with the upward displacement of the detection sheet mounting seat 11, the photoelectric sensor 4 senses the displacement signal of the detection sheet 12, the photoelectric sensor 4 converts the displacement signal into an electric signal and transmits it to the PLC control system, the PLC control system controls the defective product device to put the defective product into the defective product box. The compression spring 13 provides a downward elastic force to press the detection sheet 12 to rotate downwardly and reset to contact the photoelectric mounting base 5.

[0037] Since the application adopts the vertically sliding detection top rod 6 to drive the detection sheet 12 to rotate and swing, the photoelectric sensor 4 senses the displacement signal of the detection sheet 12 and converts it into an electric signal for transmission, thereby realizing the detection of the drum bottom 19 of the capacitor 18, and solving the problem that the lever arm detection operation needs to occupy too much plane environment.
