The coating system comprises a coating device, a thickness measuring device and a control device. The coating device is used for coating slurry on a pole piece. The thickness measuring device is used for detecting the thickness of the pole piece coated with the slurry. The coating device and the thickness measuring device are electrically connected with the control device respectively. The control device is configured to control the coating device to adjust the flow of the slurry based on the thickness of the pole piece. The coating system of the embodiment of the application can be configured to control the coating device to adjust the flow of the slurry based on the thickness of the pole piece, adjust the flow of the discharge port of the coating device, make the pole piece coated with the slurry fluctuate within a predetermined range, and reduce the probability of too thin or too thick tab glue.

This invention belongs to the technical field of vacuum coating equipment, and discloses a sample stage and high-vacuum coating equipment for high-vacuum coating. The sample stage for high-vacuum coating includes a vacuum chamber, a substrate stage, a tilting motion mechanism, a rotating motion mechanism, and a lifting motion mechanism. By setting the tilting motion mechanism, the rotating motion mechanism, and the lifting motion mechanism, the substrate stage can simultaneously have multi-degree-of-freedom motion of rotation, lifting, and tilting. Each of the three mechanisms can drive the substrate stage individually, or at least two can work together to drive the substrate stage. The sample stage used in high-vacuum coating equipment can flexibly adjust the position of the substrate stage according to different coating sources, improving the versatility of the sample stage for high-vacuum coating equipment. It can also improve the uniformity of coating on workpieces, precisely control deposition parameters, and achieve uniform coating on complex-structured irregular workpieces.

This utility model discloses an unobstructed, full-surface coating fixture, comprising: a fixture body having at least one through-cavity for completely accommodating a product; and a back-stretching high-temperature film disposed on one side of the fixture body, with an adhesive layer for bonding and fixing the product on the side near the cavity; wherein the side of the product facing away from the back-stretching high-temperature film is the coating surface. The product can be fixed in the cavity of the fixture body using the back-stretching high-temperature film and the adhesive layer, a simple and convenient fixing method; and because the cavity can completely accommodate the product, the coating surface of the product is completely open and unobstructed, thus achieving full-surface coating.
