Description

Technical Field

[0001] The utility model relates to a thermal print head protective film stacking type sputtering film forming auxiliary tooling, belonging to the technical field of thermal print head production. Background Art

[0002] The thermal print head is one of the core components of a thermal printer, which is responsible for generating text, images, barcodes and other contents on thermal paper. The ceramic substrate is an important component of the print head. The printing paper is squeezed between the printing roller and the ceramic substrate. The rotation of the printing roller drives the printing paper to move along the ceramic substrate. The extrusion part of the ceramic substrate will wear out under the action of friction for a long time. In order to improve the wear resistance of the substrate, it is usually necessary to sputter a wear-resistant layer in the contact area between the print head and the printing roller. Sputtering film formation in the specified area of ​​the substrate is difficult, the process is complex, the efficiency is low, and the utilization rate of the raw materials for film formation is low. Utility Model Content

[0003] In order to solve the defects of the prior art, the purpose of the utility model is to provide a thermal print head protective film stacking sputtering film forming auxiliary tooling, which simplifies the difficulty of sputtering film forming in a specified area of ​​a substrate, forms more film products at one time, and improves film forming efficiency.

[0004] The technical solution of the utility model is: a thermal print head protective film stacking sputtering film forming auxiliary tooling, including a film forming jig, a top of the film forming jig is obliquely provided with a receiving groove, the receiving groove includes a front end receiving groove and a baffle receiving groove located at both ends of the film forming jig, and a plurality of intermediate receiving grooves are adjacent to the front end receiving groove and the baffle receiving groove.

[0005] The width of the baffle accommodating groove and the middle accommodating groove is equal to the width of the film forming area on the substrate.

[0006] The front end receiving groove and the middle receiving groove are used to place the substrate, and the thickness of the substrate is the same as the groove depth of the front end receiving groove and the middle receiving groove. The baffle plate receiving groove is used to place the shielding plate, and the thickness of the shielding plate is the same as the groove depth of the baffle plate receiving groove.

[0007] The shielding sheet has the same size as the base sheet.

[0008] The beneficial effects of the utility model are as follows: multiple ceramic substrates are stacked and placed on a film forming fixture so that only the film forming area of ​​the substrate is exposed, thereby improving the utilization rate of the film forming raw materials; simplifying the film forming process, completing the sputtering film forming of multiple ceramic substrates at one time, and improving work efficiency.

[0012] The following is combined with Figure 1-2 The utility model is further described as follows:

[0013] A thermal print head protective film stacking sputtering film-forming auxiliary tooling includes a film-forming jig 1, and a receiving groove is obliquely arranged on the top of the film-forming jig 1. The receiving groove includes a front receiving groove 2 and a baffle receiving groove 3 located at both ends of the film-forming jig 1, and a plurality of intermediate receiving grooves 4 are adjacent to the front receiving groove 2 and the baffle receiving groove 3. The groove width W1 of the baffle receiving groove 3 and the intermediate receiving groove 4 is equal to the width W2 of the film-forming area on the substrate 5. The substrate 5 is a ceramic substrate, and its width is certain. After a plurality of substrates 5 are stacked and placed by the film-forming jig, the film-forming area is exposed, and the non-film-forming area is shielded by the adjacent substrates 5, that is, the exposed areas are all film-forming areas, and the sputtering film-forming is more accurate, and the sputtering film-forming in the non-film-forming area is avoided, saving raw materials.

[0014] The front end receiving groove 2 and the middle receiving groove 4 are used to place the substrate 5, and the thickness of the substrate 5 is the same as the groove depth of the front end receiving groove 2 and the middle receiving groove 4, so that the surface of the substrate 5 is coplanar with the bottom surface of the adjacent receiving groove, thereby making the contact surface between the front and rear stacked substrates 5 better fitted and the overall more neat, and the baffle plate receiving groove 3 is used to place the shielding plate 6, and the thickness of the shielding plate 6 is the same as the groove depth of the baffle plate receiving groove 3, and the size of the shielding plate 6 is the same as that of the substrate 5. The shielding plate 6 shields the adjacent substrates 5, so that the size of the film forming area exposed by the substrate 5 is the same as that of other substrates, ensuring the consistency of the size of the film forming area.

[0015] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
