Description

Technical Field

[0001] This utility model relates to the field of silver paste sintering furnace technology, specifically a photovoltaic conductive silver paste sintering furnace. Background Technology

[0002] Conductive pastes, as a type of functional printing material, are widely used in electronic information products due to their excellent physical properties. As electronic products develop towards being lighter, thinner, more functional, and more environmentally friendly, higher performance requirements are being placed on them. Low-temperature halogen-free conductive silver paste, in particular, is widely used in membrane switches, capacitor electrodes, and touchscreens due to its excellent conductivity, thermal conductivity, and practicality. In the photovoltaic industry, conductive silver paste requires high-temperature sintering before it can be evaluated during testing.

[0003] A photovoltaic conductive silver paste sintering furnace, as described in application number 202320920503.5, includes a sintering furnace body, hooks, a distribution box, a multi-level temperature gauge, a sliding rail, a motor, a rotating disk, a filter mechanism, a cabinet door, a sealing plug, a baffle, silicon carbide rods, and resistance wires. The sintering furnace body is equipped with hooks, and the distribution box is mounted on it. The distribution box is equipped with a multi-level temperature gauge. The sintering furnace body has a sliding rail, and the distribution box is connected to a motor. A rotating disk is mounted on the motor. A filter mechanism is located inside the sintering furnace body. A cabinet door is connected to the sintering furnace body, and a sealing plug is installed on the cabinet door. A baffle is also located inside the sintering furnace body. This invention neutralizes the heat conduction efficiency by spaced silicon carbide rods and resistance wires inside the sintering furnace body, preventing the temperature from rising too quickly or too slowly. This ensures uniform temperature within the sintering furnace body and improves the overall sintering efficiency. However, it does not allow for longitudinal rotation adjustment of the slurry, thus affecting the uniformity of slurry heating and making loading and unloading difficult. Utility Model Content

[0004] The purpose of this invention is to provide a photovoltaic conductive silver paste sintering furnace to solve the problems in the prior art where the slurry cannot be adjusted by longitudinal rotation, thus affecting the uniformity of slurry heating and making loading and unloading difficult.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic conductive silver paste sintering furnace, comprising a sintering furnace body and a material storage mechanism. The sintering furnace body has a heating chamber provided inside by a support plate. The inner wall of the heating chamber has an outer heating layer. An inner support plate is provided inside one end of the heating chamber via a rotating shaft. A positioning column is provided in the middle of one side of the inner support plate.

[0006] Furthermore, the positioning post is a quadrangular prism, and the positioning groove is a rectangular groove.

[0011] Furthermore, the positioning column has an inner heating cavity in the middle, and an inner heating rod is provided inside the inner heating cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The heating chamber of this utility model has an inner support plate that is axially rotatable at one end via a rotating shaft. The storage mechanism is inserted at one end outside the positioning column on one side of the inner support plate. This allows the storage mechanism to be driven to rotate longitudinally within the heating chamber by a motor and gear set.

[0015] 3. This utility model has an outer heating layer on the inner wall of the heating chamber and an inner heating cavity in the middle of the positioning column, and an inner heating rod in the inner heating cavity, which enables simultaneous heating of the inside and outside of the material storage mechanism. The heating rate is faster and it is beneficial to improve the sintering efficiency. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the present invention, a photovoltaic conductive silver paste sintering furnace includes a sintering furnace body 1 and a material storage mechanism. The sintering furnace body 1 is provided with a heating chamber 3 through a support plate 2. The inner wall of the heating chamber 3 is provided with an outer heating layer 4, which is an electric heating wire. The positioning column 5 is provided with an inner heating cavity in the middle, and an inner heating rod 6 is provided in the inner heating cavity, so that the material storage mechanism can be heated simultaneously inside and outside, the heating rate is faster, and it is beneficial to improve the sintering efficiency.

[0024] like Figure 1 and Figure 3 As shown, in order to ensure sufficient heating for the longitudinal rotation adjustment of the slurry, an inner support plate 7 is axially rotatable inside one end of the heating chamber 3 via a rotating shaft. A positioning column 5 is located in the middle of one side of the inner support plate 7. An electric motor is connected to the outer side of the inner support plate 7 via a gear set. The gear set includes a driven gear ring 8 located outside the inner support plate 7. One end of the electric motor is connected to a driving gear 9 that meshes with the driven gear ring 8 via a connecting shaft 10. The electric motor is fixedly located outside the sintering furnace body 1. One end of the storage mechanism is inserted outside the positioning column 5 on one side of the inner support plate 7. This allows the storage mechanism to be driven to rotate longitudinally within the heating chamber 3 via the electric motor and gear set, thereby ensuring sufficient heating for the longitudinal rotation adjustment of the slurry within the storage mechanism. At the same time, the slurry is always spread evenly at the bottom of the storage bin 15, which helps to improve the uniformity of slurry heating.

[0025] like Figure 2 and Figure 3 As shown, in order to facilitate the loading and unloading of materials into the furnace, the material storage mechanism includes an inner support seat 11. One end of the inner support seat 11 has a positioning groove 12 that is inserted and matched with the positioning column 5, which facilitates the disassembly and assembly of the material storage mechanism. At the same time, an outer support cylinder 14 is threaded on the outer side of the limiting seat 17 at one end of the inner support seat 11. The outer side of the limiting seat 17 has an external thread 20. The inner wall of one end of the outer support cylinder 14 has an internal thread 19 that is threaded to the external thread 20. A material storage bin 15 is provided between the inner support seat 11 and the outer support cylinder 14, which facilitates the disassembly and assembly of the outer support cylinder 14 and the inner support seat 11, thereby facilitating the loading and unloading of materials into the material storage bin 15.

[0026] like Figure 2 and Figure 3 As shown, in order to improve the stability of the connection and fixation between the inner support base 11 and the positioning post 5, the positioning post 5 is also set as a quadrangular prism, and the positioning groove 12 is a rectangular groove. The positioning post 5 is a metal post, and a magnet block 13 is provided on the inner wall of one end of the positioning groove 12. A sealing ring 18 is provided on one end of the outer support cylinder 14, and a handle 16 is provided in the middle of one end of the outer support cylinder 14. This makes it easier to improve the stability of the connection and fixation between the inner support base 11 and the positioning post 5, and also makes disassembly and assembly convenient and quick.

[0027] The working principle and usage process of this utility model are as follows: When in use, the slurry is placed in the storage mechanism, and then one end of the storage mechanism is inserted into the outside of the positioning column 5 on one side of the inner support plate 7. Since the inner support plate 7 is axially rotated inside the heating chamber 3 through a rotating shaft, and the outer side of the inner support plate 7 is connected to the motor through a gear set, the storage mechanism can be driven to rotate longitudinally in the heating chamber 3 by the motor and gear set. This allows the slurry in the storage mechanism to be fully heated by longitudinal rotation adjustment, and at the same time, the slurry can be spread evenly at the bottom of the storage bin 15, which facilitates the improvement of the uniformity of slurry heating.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
