Battery module welding method and system

The invention provides a battery module welding method and system. The battery module welding method comprises the following steps that 1, an initial X coordinate and an initial Z coordinate of any welding point of the battery module are detected by a 2D scanner; 2, an adjusted X coordinate and an adjusted Z coordinate of the welding point are acquired according to the initial X coordinate, the initial Z coordinate and a preset deviation value of the welding point; and 3, welding is carried out on the welding point through a PLC welding system according to the adjusted X coordinate, the adjusted Z coordinate and a preset Y coordinate of the welding point. According to the battery module welding method and system, the 2D scanner adopts laser detection and is not limited by the glossiness ofa metal surface, and therefore the welding point is basically detected, the X coordinate and the Z coordinate of the welding point can be detected, height measurement is omitted, the accuracy is improved, the welding percent of pass is high, and the welding speed is greatly improved; and meanwhile, all the welding points of the battery module can be detected only by one step by the 2D scanner, and therefore the overall efficiency of the machine is improved.

Method for determining and optimizing power parameters in manufacturing process of plasma display screen

The invention discloses a method for determining and optimizing power parameters in the manufacturing process of a plasma display screen. A regression relation model of the important power parameters and yield in the manufacturing process of the plasma display screen is established by utilizing the historical data of the manufacturing process and the importance degree influencing the quality of a plasma display screen product is reflected by utilizing a regression coefficient, so that important power parameter items which need to be subjected to management and control reinforcement with emphasis are determined and a power parameter control strategy for promoting the total yield or the single-process yield is found. The method has the active effects that time and resource cost which are consumed in a manner of repeatedly carrying out testing design and verification are saved and direction accuracy on the aspects of power parameter control items and the control range is promoted; and moreover, the aim of continuously and spirally promoting the yield of the plasma display screen can be fulfilled and the rejection rate in the manufacturing process is indirectly reduced. Meanwhile, the method disclosed by the invention cannot be related to the interruption of production of a production line, so that online dynamic determination and regulation management of the power parameters of the manufacturing process are implemented.

Polarized light irradiation device for photo-alignment and polarized-light irradiation method for photo-alignment

The invention provides a polarized light irradiation apparatus and method for photo-alignment, which is capable of detecting the direction of a polarization axis of irradiated polarized light in high precision and performing photo-alignment treatment in high quality in the aspect of direction precision. A workpiece (W) is arranged on an irradiation surface (R). When the workpiece (W) is irradiated by the polarized light by virtue of irradiating the irradiation surface (R) through a polarized element (121), a polarization direction detector (40) is arranged on the irradiation surface (R) and detects the direction of the polarization axis of the polarized light. A polarization analyzer arranged in the polarization direction detector (40) is located in advance by a polarization analyzer calibrator, and a rotary original point is at a specified angle with respect to the reference direction of the apparatus. Based on the polarization direction detected by the polarization direction detector (40), the deviation of the polarization axis can be obtained and by using a polarized element adjusting mechanism (7) to adjust the posture of the polarized element (121), the deviation can be eliminated.
