The application discloses an automatic wire threading cutting machine and belongs to the field of wire cutting equipment. The automatic wire threading cutting machine comprises a rack, a wire source device, a lifting device, a wire threading device, an upper wire guide, a sleeve and a sensor, the wire source device, the lifting device and the wire threading device are installed on the rack, the upper wire guide is installed on the lifting device, the sleeve is sleeved on the upper wire guide in a lifting manner, the sensor is arranged at a position matched with the sleeve, and the lifting device is used for driving the upper wire guide and the sleeve to lift. When the lifting device makes the distance between the end of the upper wire guide and the workpiece reach a preset distance, the sleeve is connected with the workpiece, and the sensor is triggered. The application detects the position of the upper wire guide and the workpiece in the case that the upper wire guide is not connected with the workpiece by cooperation of the sensor and the sleeve, reduces the probability that the bottom of the eye mold installed on the upper wire guide deviates, and solves the problem that the existing technology is prone to deviation of the eye mold, thereby reducing the precision of automatic wire threading wire cutting.

This invention provides a low-temperature line-source evaporation deposition apparatus. The apparatus includes a crucible, a heat spreader, a heating wire, a heating electrode, a thermocouple, a water-cooling pipe, and a heat-insulating shielding layer. The heat spreader has a crucible groove milled into its inner side and a heating wire groove milled into its outer side, with a hole at the bottom. The crucible is placed in the crucible groove, the heating wire is embedded in the groove, and the thermocouple is inserted into the hole below the crucible. The water-cooling pipe is located outside the heat spreader, and the heat-insulating shielding layer is located outside the water-cooling pipe. A baffle is placed around the heat-insulating shielding layer to form a heat-insulating cavity. Using this low-temperature line-source evaporation deposition apparatus, heat is conducted between the heating wire, heat spreader, and crucible through contact, enabling rapid and uniform heating of the crucible and effectively reducing the loss of the evaporation material. The linear temperature field uniformity can be controlled within 0.1℃, thus ensuring uniform evaporation rate. The resulting film material has good thickness uniformity and density, significantly improving the efficiency of photovoltaic cells.

The embodiment of the application provides a kind of evaporation device, including at least two line source assemblies;Each line source assembly includes short line source and probe respectively arranged at both ends of short line source along the length direction of short line source;Short line source includes outlet, for providing evaporation material to the substrate to be evaporated, and probe is used to monitor the evaporation rate of evaporation material;At least two line source assemblies are staggered in the first direction perpendicular to the conveying direction of the substrate to be evaporated, so that the substrate is completely and uniformly evaporated in the first direction. Meanwhile, uniform evaporation of large-width substrate and accurate monitoring of material evaporation rate of line source are realized, the cost of evaporation source is reduced, and the material utilization is improved.
