A coating device and coating method for inner electrode of sensor u-shaped zirconia matrix

Abstract

The invention relates to the technical field of internal electrode coating, in particular to a sensor U-shaped zirconia matrix internal electrode coating device, which includes a support platform, a fixed rotating jig arranged at one end of the support platform through a lifting device, and the fixed rotating jig Connected with the output shaft of the motor, the other end of the support table is provided with a sliding seat, and a linear slider is provided on the sliding seat, and the linear slider is fixed on the needle cylinder, and the needle cylinder is horizontally provided with a needle through the pipeline. The needle head is arranged correspondingly to the rotating jig; the syringe is connected to the trace gas controller through a hose, and the sliding seat is electrically connected to the controller to control the linear slider to slide left and right; at the same time, the invention discloses the use of the above device to carry out Method of coating. The invention has the advantages of controllable coating speed, precise positioning, material saving and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of internal electrode coating, in particular to a sensor U-shaped zirconia matrix internal electrode coating device and coating method. Background technique [0002] The U-shaped zirconia matrix of the sensor has a trumpet-like structure, so it has always been a technical problem to coat the inner electrodes. The existing coating mainly includes the following types: 1. Manual hand coating method, that is, the coating liquid is coated individually with a brush and other equipment. The defect is that the production efficiency is low, and the coating uniformity is poor. The volatile substances in the liquid will have adverse effects on the body of the operator; 2. The spray method, that is, the spray gun is used to spray the coating liquid into the inner electrode. Although this method solves the uniformity problem to a certain extent, there are Serious deficiency and defect of coating solution waste; 3, the m...

The existing coating mainly includes the following types: 1. Manual hand coating method, that is, the coating liquid is coated individually with a brush and other equipment. The defect is that the production efficiency is low, and the coating uniformity is poor. The volatile substances in the liquid will have adverse effects on the body of the operator; 2. The spray method, that is, the spray gun is used to spray the coating liquid into the inner electrode. Although this method solves the uniformity problem to a certain extent, there are Serious shortage and defect of coating liquid waste; 3. Pour in and pour out method, that is, pour the coating liquid into the rear inner electrode and then pour it out. This method also has the defects and deficiencies of wasting coating liquid and low production efficiency
