Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0015] The positioning template provided by the present invention is as figure 1 As shown: the positioning plate 1 is hinged on the workbench (not shown in the figure) of the silver printing machine. There are several positioning holes 4 distributed on the surface of the positioning plate, and each positioning hole 4 passes through the air passage 5 arranged inside the positioning plate 1 It communicates with the vacuum pump (not shown in the figure) of the silver printing machine; a material plate 6 is fixed on the workbench, and a number of storage holes 8 corresponding to the positions of the positioning holes 4 are distributed on the surface of the material plate, and each material storage hole 8 There is spring 7 in it.

[0016] like figure 1 Shown, the operating steps of the inventive method are as follows:

[0017] 1) Stack two layers of pi...

Abstract

The invention discloses a silver printing positioning template of piezoelectric ceramic pieces and a silver printing method of the piezoelectric ceramic pieces and aims for providing a positioning template capable of improving printing efficiency and utilizing the positioning template to print a metallic silver coating on the surface of the piezoelectric ceramic piece. The silver printing positioning template comprises a positioning plate provided with positioning holes and hinged to a workbench, and the positioning holes (4) are communicated with a vacuum pump through an air passage (5); a material plate (6) is arranged on the workbench, and material storing holes (8) are formed in the surface of the material plate and provided with springs (7). The piezoelectric ceramic pieces (2) are arranged in the material storing holes (8) in an overlapped manner to enable the positioning holes (4) to be in butt joint with the material storing holes (8); the piezoelectric ceramic pieces (2) are absorbed in the positioning holes (4); a silk screen (3) covers the surface of a positioning plate (1), and the surfaces of the piezoelectric ceramic pieces (2) are coated with silver paste; the positioning plate (1) is taken down to be fed into a drying oven to have the silver paste dried.

Description

technical field [0001] The invention relates to a printing positioning template, in particular to a positioning template for printing metallic silver coating on the surface of piezoelectric ceramic sheet, which belongs to technological equipment; Method for making metallic silver coatings. Background technique [0002] Piezoelectric ceramic sheets are materials for making electronic components such as buzzers and thermistors. The products are thin and small and easy to break. At present, the metal silver coating is usually printed on the surface by manual single-chip printing: it is to fix the positioning plate with vacuum adsorption positioning holes on the workbench of the silver printing machine, and place the piezoelectric ceramic sheet in the positioning holes. In the process, turn on the vacuum pump to absorb and fix the piezoelectric ceramic sheet, then brush the silver paste on the surface of the piezoelectric ceramic sheet through the screen, take out the piezoelec...
