TECHNICAL FIELD

[0001] The utility model relates to coating machine technical field especially relates to a conveying belt coating device. BACKGROUND

[0002] In the photovoltaic industry, silver paste coating is a crucial process. As one of the key materials for photovoltaic cells, the coating thickness of silver paste is usually precisely controlled within a few microns to maximize the photoelectric conversion efficiency of photovoltaic cells. However, silver paste itself has poor fluidity, which increases the difficulty of coating and puts strict requirements on the precision and performance of the coating device.

[0003] Traditional ordinary coating machines often fail to achieve the expected coating effect when faced with such high-precision, high-difficulty silver paste coating tasks. During the coating process, traditional coating machines have difficulty in precisely controlling the coating amount and uniformity of silver paste, which often leads to inconsistent coating thickness, unstable coating quality, and a series of other problems. Due to the poor fluidity of silver paste, traditional coating machines cannot effectively promote the uniform dispersion of silver paste and precisely coat it onto the target carrier board. This not only affects the photoelectric conversion efficiency of photovoltaic products but also may lead to a decline in the overall performance of the products.

[0004] In view of the above problems, we urgently need to design a conveying belt coating device. INVENTION CONTENTS

[0007] Optionally, the power assembly includes a double-shaft motor, a shaft, a belt pulley assembly, a conveying belt body, and a conveying wheel. The double-shaft motor is installed on the right side of the support frame. Both ends of the double-shaft motor are provided with shafts.

The front and rear ends of the upper conveying wheel are connected with the two shafts through the belt pulley assembly.

[0024] When the belt coating device is needed to be used, first of all, make sure that the belt coating device has been correctly installed and firmly in the desired position. Then, check whether the main cavity 2 inside has been filled with the appropriate amount of silver paste to ensure the smooth progress of the coating process. At the same time, check whether the nozzle 3 is clean and working properly, which is the key to ensuring that it can accurately control the amount and time of silver paste.
