The specific detection method does not belong to the protection key points of the utility model, and therefore is not described here.

[0023] The wire body assembly 3 comprises transmission lines 31 and a supporting roller assembly 35 arranged between the transmission lines 31. The transmission line 31 adopts a conventional synchronous belt transmission, that is, comprises a synchronous belt wheel and a synchronous belt arranged on the synchronous belt wheel, and one side of the synchronous belt wheel is provided with a driving motor. The area of the photovoltaic module is generally large, and in order to better transmit, the combination of the supporting roller assembly and the transmission line 31 can make the transmission more stable.

The adjusting assembly is an adjusting sliding rail, and the setting direction of the adjusting sliding rail is consistent with the transmission direction. When limiting is needed, the cylinder 33 drives the limiting wheel 34 to rise and limit one side of the photovoltaic module entering the transmission line, and when the photovoltaic module needs to be transmitted out of the device, the cylinder 33 drives the limiting wheel 34 to move downward to give way.

[0025] In order to avoid the deviation of the photovoltaic module when entering the rack, the left and right sides of the conveying line are provided with a guide assembly 32. The left and right sides of the conveying line here refer to the left and right sides of the outermost end of the entire conveying line in the overall device, that is, the two sides of the outer edge of the photovoltaic module.

[0029] After the components are detected and spot tacked by the device, the components are conveyed out of the rack from the other side of the rack. At this time, when passing through the other side of the rack, the spot tacked components can be detected by a visual scanning assembly arranged above the conveying-out side of the rack. The structure of the visual scanning assembly after spot tacking is the same as that of the visual scanning assembly before spot tacking, and both of them comprise an image acquisition mechanism and a light supplementing assembly arranged below the image acquisition mechanism.
