The cap arranging mechanism 2 is arranged at a front end of the sheet base strip 11. The cap arranging mechanism 2 is used for arranging and debugging pull-tab caps 200. The light detection mechanism 3 is arranged at a middle part of the sheet base strip 11. The light detection mechanism 3 is used for detecting defects of the pull-tab caps. The cap kicking mechanism 4 is arranged at a rear end of the sheet base strip 11. The cap kicking mechanism 4 is used for removing unqualified pull-tab caps according to a detection mechanism of the light detection mechanism 3.

[0050] The pull-tab cap finished product detection equipment 100 further comprises a control mechanism which is in communication connection with the conveying mechanism 1, the cap arranging mechanism 2, the light detection mechanism 3 and the cap kicking mechanism 4. The whole process is controlled by the control mechanism. In particular, when the light detection mechanism 3 detects unqualified products, the control mechanism controls the cap kicking mechanism 4 to remove the unqualified products.

[0051] The conveying mechanism 1 of the technical scheme can convey the pull-tab caps from the front end to the rear end.

Since the cap arranging mechanism 2 is arranged to remove the debugging pull-tab caps 200 when the punch machine is started, the debugging pull-tab caps 200 are prevented from being conveyed to the rear end and mixed with the qualified finished products, the detection efficiency is improved, the product quality is ensured, and the equipment space is saved.

The tension of the sheet base strip 11 can be adjusted according to actual conditions by the tension wheel 123. The output end of the conveying motor 121 is connected with the conveying wheel 122 through a belt 125. The conveying wheel 122 and the tension wheel 123 are in transmission connection through the belt 125. The tension wheel 123 and the sheet base strip 11 are also in transmission connection through the belt 125. Preferably, a transmission wheel 124 can be arranged between the conveying wheel 122 and the tension wheel 123. The transmission wheel 124 is arranged between the tension wheel 123 and the sheet base strip. The transmission wheel 124 plays a role of intermediate transmission.

The rotary cylinder 21 is used to drive the stopper 23 to rotate, so that the stopper 23 arranges the debug pull-tab cover 200 on the base strip 11 into the cover arranging chute 22.

[0055] Thus, the stopper 23 is driven to rotate towards the base strip direction under the action of the rotary cylinder 21, and the stopper 23 forms an included angle to arrange the debug pull-tab cover 200 on the base strip 11 into the cover arranging chute 22.
