In this embodiment, the detection element 7 is arranged on the electric conveying cylinder.

The working process of the automatic online weighing system for solar cells is as follows:

Before printing, the solar battery sheet 200 is conveyed along the forward and backward direction on the transmission belt 100. When the solar battery sheet 200 is conveyed to the working range of the weighing machine before printing, the detection element 7 detects that the solar battery sheet 200 is on the transmission belt 100. At the specific position on the top, the detection element 7 sends a signal to the controller, and the controller controls the transmission of the transmission belt 100 and stops the solar battery sheet 200 at the required position, even if the solar battery sheet 200 stops above the top sheet cylinder; then control The device controls the action of the top film cylinder, so that the push rod of the top film cylinder moves upwards, which makes the solar battery sheet 200 be jacked up, and is higher than the transmission belt 100, between the lower surface of the solar battery sheet 200 and the upper surface of the transmission belt 100 There will be a gap between them; at this time, the controller controls the movement of the electric cylinder to make the slider slide left and right relative to the second cylinder body. When the slider slides, it drives the lifting cylinder and the bracket 4 to slide in the left and right direction relative to the frame 1 synchronously. Until the carriage 4 is transported to the gap between the lower surface of the solar cell sheet 200 and the upper surface of the transmission belt 100 so that the support plate 42 of the carriage 4 is positioned; the controller controls the top sheet cylinder to move again, so that the top sheet cylinder The push rod moves downward, and the solar cell 200 falls on the support plate 42 of the bracket 4; then the controller controls the lifting cylinder to move up the pull rod, and the pull rod drives the bracket 4 and the solar cell 200 to rise to a certain height synchronously; The controller controls the transfer electric cylinder to move again, so that the slider slides in the opposite direction relative to the second cylinder and gradually approaches the weighing module 2, until the bracket 4 and the solar cell 200 are transferred to the weighing module together 2, at this time, the support plates 42 are respectively located on both sides of the weighing module 2; then the controller controls the lifting cylinder to move again to lower the pull rod and drive the bracket 4 to drop together, which will make the solar cells 200 and the bracket The frame 4 is separated, so that the solar cells 200 fall on the weighing module 2; then the weighing module 2 obtains the weight of the solar cells 200 before printing, that is, the dry weight, and sends the dry weight value to the controller ;

Operate the transfer mechanism in reverse according to the above steps, move the solar cell 200 from the weighing module 2 back to the transmission belt 100 before printing, and then transfer the solar cell 200 to the printing station by the transmission belt 100, after the printing is completed , the solar cells 200 are sent out by the printed transmission belt 100 through the printing station;

When the solar cells 200 are delivered to the working range of the weighing machine after printing, the weighing machine will work, and its working process is the same as that of the weighing machine before printing, so it will not be repeated here. The weight module 2 obtains the weight of the solar cell 200 after printing, that is, the wet weight, and sends the wet weight value to the controller;

Finally, the weight of the printed paste (silver paste or aluminum paste) is calculated by the controller and displayed on the display on the printing machine in real time, the weight = wet weight - dry weight, and the printing can be further evaluated by the weight of the printed paste quality and stability.

The above-mentioned embodiments are only to illustrate the technical conception and characteristics of the present utility model. Equivalent changes or modifications made by the spirit of the present utility model shall be covered within the protection scope of the present utility model.
