Description

Technical Field

[0001] The utility model belongs to the field of electronic component devices, and further relates to the field of ceramic substrate devices, and specifically, to a compatible double-sided silver-coated substrate drying device. Background Art

[0002] After the ceramic substrate is produced, it is generally necessary to coat silver paste on the front and back of the substrate, and then form electrodes after drying and firing.

[0003] The existing technology for drying silver-coated ceramic substrates is mainly single-sided drying. That is, the substrate that has been silver-coated on one side is manually placed in a fixture (the silver-coated side faces up), and then the fixture is sent into an oven for drying. This method is only applicable to single-sided silver-coated substrates and cannot be used to dry substrates that have been silver-coated on both sides.

[0004] The utility model aims to invent a double-sided silver-coated substrate drying device, which doubles the drying efficiency by drying the front and back silver-coated surfaces of the ceramic substrate at the same time. In addition, the drying device is compatible with ceramic substrates of various sizes and specifications.

[0005] In view of this, the present utility model is proposed. Summary of the invention

[0006] The technical problem to be solved by the utility model is to solve the problem that the prior art can only dry a single-sided silver-coated substrate, the drying efficiency is low, and the double-sided silver-coated substrate cannot be dried.

[0007] The inventive concept of the utility model is to adopt a drawer-type suspended design method, that is, to improve the design of a traditional drawer so as to make it suitable for the current size requirements and drying requirements of ceramic substrates.

[0008] To this end, the utility model provides a compatible double-sided silver-coated substrate drying device, such as Figure 1-9 shown.

[0009] It includes a drawer-type ceramic substrate drying platform 1, which can achieve double-sided drying; a cabinet 2 used with the platform, according to the needs, a number of drying positions (more than 2) are designed, such as Figure 1 shown.

[0010] The drawer-type ceramic substrate drying platform 1 comprises: a platform baffle 101, a platform bottom plate 102, a suspended substrate support 103, a handle 104, and a handle support rod 105. Figure 2 As shown, the explosion diagram is as follows Figure 3 shown.

[0011] The platform baffle 101 is used together with the platform bottom plate 102 to form a square drawer shape. Figure 4-5 shown.

[0012] The suspended wafer support platform 103 adopts a hollow design and is a hollow structure that gradually decreases from top to bottom. The shape and size of the hollow structure are determined by the shape and size of the ceramic substrate. The gradually decreasing peripheral wall slope 10301 of the hollow structure is used to place and fix the ceramic substrate. A ceramic substrate access opening 10302 is opened along the side wall of the hollow structure for taking and placing the ceramic substrate. The upper and lower bottom sizes of the hollow structure are determined according to the maximum and minimum sizes of the ceramic substrate. Figure 6 shown.

[0013] The handle 104 is used together with the handle support rod 105 to facilitate pulling out the drawer-type ceramic substrate drying platform. Figure 7-8 shown.

[0014] The assembly diagram of the cabinet 2 used by the supporting platform is as follows Fig. 9 shown.

[0015] Compared with the existing single-sided drying process, the utility model:

[0016] A drawer-type ceramic substrate drying carrier is used to achieve double-sided drying of double-sided silver-coated substrates.

[0017] There are several drawer-type ceramic substrate drying platforms, and the cabinet used with the platforms can be designed with several drying positions, which greatly improves the drying efficiency. Due to the hollowness and transparency, the drying quality is consistent, the production repeatability is good, and the reliability is high.

[0018] The utility model adopts a prism hollowing design, which directly solves the problem of drying the double-sided silver-coated substrate and is compatible with ceramic substrates of products of different specifications.

[0019] The utility model is not only suitable for the silver coating and drying process of ceramic substrates, but also suitable for the drying process of various regular-shaped products, and is widely used in the technical field of drying process of large quantities of silver-coated substrates.

DETAILED DESCRIPTION

[0030] like Figure 1-9 As shown, the compatible double-sided silver-coated substrate drying device is specifically implemented as follows:

[0031] The cabinet 2 used in the supporting platform is made of metal materials with good heat dissipation, such as copper, aluminum, aluminum alloy, stainless steel, etc., and is designed with 8 drying positions, such as Figure 1 shown.

[0032] The ceramic substrate is square.

[0033] The hollow structure is a hollow inverted trapezoidal structure, including an inverted trapezoidal inclined surface 10301 for placing and fixing a ceramic substrate. A ceramic substrate access opening 10302 for accessing and placing a ceramic substrate. The upper and lower base sizes of the hollow inverted trapezoidal structure are determined according to the maximum and minimum sizes of the ceramic substrate. Figure 6 shown.

[0034] Description of the action relationship of the drawer-type ceramic substrate drying platform 1:

[0035] The platform baffle 101 and the platform bottom plate 102 are spliced ​​and combined using welding technology to form the basic style of a drawer. Among them, the height of the platform baffle 103 is slightly higher than the height of the drying position of the cabinet 2, so that the platform will not completely enter the cabinet, which is convenient for taking and placing. The suspended wafer platform 103 is welded on the platform baffle 101, and the welding height is centered. The suspended wafer platform 103 needs to be made using a professional mold. The prism hollowing design makes it have a larger slope and can be adapted to ceramic substrates of different specifications and sizes. After the handle 104 and the handle support rod 105 are welded together, they are welded to the platform baffle 101, which can facilitate the platform to be taken out of the cabinet.

[0036] Working principle:

[0037] Utilize the thermal radiation of the temperature field and the thermal effect of the material. When the double-sided silver-coated substrate is placed in the cabinet and sent into the oven, after a long period of thermal radiation, the cabinet can also be regarded as a small oven. At this time, the silver paste on the surface of the substrate will be dried quickly. The suspended wafer carrier adopts a prism-shaped hollow design, which not only prevents the silver paste coated on both sides of the substrate from being rubbed off during the drying process, but also can be adapted to ceramic substrates of different sizes. The cabinet material has good thermal conductivity and fast heat dissipation. It can heat up quickly in the oven and cool down quickly after being taken out.

[0038] The utility model provides a compatible double-sided silver-coated substrate drying device, and the use method thereof is as follows:

[0039] First, place the double-sided silver-coated substrate on a wafer stage, which can accommodate ceramic substrates of different sizes.

[0040] Secondly, the drawer is placed in the cabinet, and the cabinet with the silver-coated substrate is sent into the oven for drying.

[0041] Finally, when the drying time is up, take out the cabinet from the oven and take out the dried silver-coated substrate.

[0042] Finally, it should be noted that the above embodiments are only examples for clear explanation. The present utility model includes but is not limited to the above embodiments. It is not necessary and impossible to list all implementation methods here. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. All implementation methods that meet the requirements of the present utility model belong to the protection scope of the present utility model.
