Description

Technical Field

[0001] The utility model belongs to the technical field of positioning tooling, in particular to a positioning tooling for printing ceramic component electrodes. Background Art

[0002] Piezoelectric ceramics are information functional materials that can convert mechanical energy and electrical energy into each other. Ceramics are generally divided into positive and negative poles. When in use, a conductive layer needs to be coated on the surface of the two poles. The most common one is a silver electrode layer. In practical applications, screen printing is usually used to print silver electrodes on piezoelectric ceramic sheets. In order to make the electrode pattern on the screen and the ceramic sheet be at the same center, the ceramic sheet needs to be limited during printing. Generally, a corresponding pit-type printing bottom mold is designed according to the actual size of the ceramic sheet. However, due to the size limitations of this bottom mold, a bottom mold of one size can generally only be used for one or several products, and piezoelectric ceramic products are rich in variety and the sizes are not uniform. Therefore, many sizes of bottom molds are required for adaptation, which is costly. Therefore, it is necessary to develop a printing positioning tool with a simple structure, easy disassembly, and strong versatility to save costs. Utility Model Content

[0003] The purpose of the utility model is to provide a positioning tool for printing ceramic component electrodes. The positioning tool can meet the use requirements by simply combining standardized positioning blocks of different thicknesses according to the thickness of the product, thereby saving the cost and time of making the printing base mold.

[0004] In order to solve the above technical problems, the present invention provides a positioning tool for printing ceramic component electrodes, comprising:

[0005] The positioning block is a rectangular block structure with threaded holes symmetrically opened at both ends;

[0006] The positioning clamping base plate is evenly provided with two threaded holes, and the threaded holes are distributed in a rectangular array; at the same time, the two positioning blocks are detachably fixed to the positioning clamping base plate at right angles, and the positioning clamping base plate is detachably fixed to the screen printing table.

[0007] Preferably, the threaded hole 1 is a structure with an upper countersunk hole and a lower through hole.

[0008] Preferably, the second threaded hole is a threaded through hole structure.

[0009] Preferably, the positioning block is detachably fixed to the positioning clamping base plate through screws, the first threaded hole and the second threaded hole.

[0010] Preferably, it further comprises fixed threaded through holes, and the four corners of the positioning and clamping base plate are symmetrically provided with the fixed threaded through holes, so that the positioning and clamping base plate can be detachably fixed to the screen printing table through screws and the fixed threaded through holes.

[0011] Preferably, the thickness of the positioning block can be set to several different thicknesses, including but not limited to 5 mm, 3 mm, 2 mm and 1 mm.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model has a simple structure and is easy to disassemble, suitable for positioning printed electrodes on piezoelectric ceramic discs, rings, and rectangular sheets of varying sizes. This fixture uses two standardized positioning blocks assembled at right angles to position the ceramic sheet to be printed. Unlike recessed printing molds, which can only accommodate one or a few products, this positioning fixture can simply combine standardized positioning blocks of varying thicknesses based on the product's thickness to meet specific needs. This reduces the cost and time required to produce the printing mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0018] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides a positioning tool for printing ceramic component electrodes, comprising:

[0019] The positioning block 1 is a rectangular block structure, and threaded holes 11 are symmetrically opened at both ends;

[0020] The positioning clamping base plate 2 is evenly provided with threaded holes 21, and the threaded holes 21 are distributed in a rectangular array; at the same time, the two positioning blocks 1 are detachably fixed to the positioning clamping base plate 2 at right angles, and the positioning clamping base plate 2 is detachably fixed to the screen printing table.

[0021] The threaded hole 11 is a structure with an upper countersunk hole and a lower through hole.

[0022] The second threaded hole 21 is a threaded through hole structure.

[0023] The positioning block 1 is detachably fixed to the positioning clamping base plate 2 by means of screws, threaded hole 11 and threaded hole 21 .

[0024] It also includes fixed threaded through holes 22. The four corners of the positioning and clamping base plate 2 are symmetrically provided with fixed threaded through holes 22 so that the positioning and clamping base plate 2 can be detachably fixed to the screen printing table through screws and the fixed threaded through holes 22.

[0025] The present invention designs a new type of tooling suitable for limiting the position of piezoelectric ceramic discs, rings, and rectangular pieces of various sizes during flat screen printing. Specifically, a positioning clamping base plate 2 and several positioning blocks 1 of different thicknesses, such as 5mm, 3mm, 2mm, and 1mm, are manufactured. A combination of positioning blocks 1 of appropriate thickness is selected based on the actual thickness of the product. The positioning blocks 1 are then screwed to the positioning clamping base plate 2 at right angles. The positioning clamping base plate 2 is then secured to the screen printing table. After the ceramic piece 3 to be printed is placed in the limiting position of the positioning block 1, the position is fine-tuned so that the corresponding patterns on the ceramic piece and the screen plate are centered, and the screen printing operation is then performed.

[0026] The tooling designed in this utility model is not limited by the size of piezoelectric ceramic discs, rings, and rectangular pieces, and has strong versatility. It improves the original printing base mold into a positioning base plate and positioning block 1 that can be standardized. The various parts of the tooling are connected by screws, which makes it easy to load and unload, simple to operate, and highly practical. This tooling solves the problem of each product corresponding to a printing base mold, the high cost of making base molds when there are many types of products, and the difficulty in managing too many types of base molds. It reduces the cost and time of making base molds and shortens the production cycle of new products. In addition, the relative position of the positioning block 1 can be adjusted to change the direction of picking up the ceramic piece, making it more convenient for the operator to operate.

[0027] The above description is only a description of the preferred embodiment of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
