Description

Technical Field

[0001] The present application relates to the field of battery processing technology, and in particular to a control system of a diaphragm pump and a boron expansion machine. Background Art

[0002] Energy is the foundation of world economic and social development. With the consumption of traditional fossil energy and the deterioration of the human living environment, the development of clean and renewable energy has attracted great attention.

[0003] With the continuous development of high-efficiency battery technology, many new technologies have been developed successively, such as: P-type passivated emitter and back contact (PERC) solar cell technology, N-type passivated emitter back local diffusion (PERL) solar technology, silicon-based heterojunction (SHJ) solar technology, N-type tunneling oxide passivation contact (TOPCON) solar cell technology, back junction back contact (IBC) solar technology, etc.

[0004] The boron diffusion process is an important process in the TOPCON process. Its purpose is to diffuse N(P) type impurities on a P(N) type substrate to form a PN junction, achieve a suitable doping concentration ρ / square resistance R, and obtain a junction depth, doping concentration ρ, and square resistance R suitable for the PN junction of a solar cell.

[0005] The chemical diaphragm pump is an excellent solution for continuous, oil-free pumping of gases during the boron expansion process, with an excellent ultimate vacuum of up to 1.5mbar. Due to its high pumping speed, this pump is a good choice for high gas load applications or vacuum boxes that require rapid pumping to negative pressure. All wetted parts are made of aluminum, stainless steel and carefully selected plastics. Suitable for a wide range of non-corrosive gas applications, it can automatically adjust its motor speed to maintain the required vacuum. This means that the pump runs very quietly, has ultra-low vibrations and has a good seal. The highly flexible fiber-reinforced double FKM diaphragm is ideal for extending the service life of the pump. The design includes a variable frequency pump and a vacuum controller with an external sensor. The on-demand motor speed control further extends the already long service life of the diaphragm and valve. And oil-free operation means there is no risk of backflow contamination.

[0006] In the process route of N-type TopCon, the diaphragm pump in the boron expansion process, as an important component of the vacuum environment, plays an important role in creating the vacuum environment of the furnace tube.

[0007] In the existing boron expansion machine, the diaphragm pump is placed in an exhaust cabinet with a high temperature, averaging 50-100°C, and there is boron oxide dust, which is corrosive. In this environment, the life of the electronic control part is only 3 months, and sudden damage often occurs, resulting in abnormal rework in batches.

[0008] To address the above-mentioned problems, no effective solution has been proposed yet. Utility Model Content

[0011] According to another aspect of the embodiment of the present application, a boron expansion machine is also provided, including the control system of the above-mentioned diaphragm pump.

[0012] In an embodiment of the present application, the control system of the diaphragm pump of the present application includes: an exhaust gas cabinet, an installation cabinet, a partition, an electrical box, a control panel and a quick connector.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0021] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0024] According to one aspect of the embodiments of the present application, an embodiment of a control system for a diaphragm pump is provided, in which the control electrical box and control panel of the diaphragm pump are removed, an extension line is added, and the control electrical box and control panel are moved to a separate clean cabinet at normal temperature. Figure 1 is a schematic diagram of an optional diaphragm pump control system according to an embodiment of the present application, such as Figure 1 As shown:

[0025] Exhaust cabinet 1, installation cabinet 2, partition 3, electric box 4, control panel 5 and quick connector 6;

[0026] The diaphragm pump is installed in the waste gas cabinet, and a through hole is opened on the waste gas cabinet, and the power line, thin film silicon control line and communication network line of the diaphragm pump are all led out from the through hole;

[0027] The electric box, the control panel and the quick connector are all mounted on the partition, the partition is mounted on the installation cabinet, the control panel and the electric box are connected to the quick connector, and the power line of the diaphragm pump, the thin film silicon control line and the communication network line are led out from the through hole and connected to the quick connector;

[0028] The spacing distance between the installation cabinet and the exhaust cabinet reaches a preset distance, such as more than 5 meters.

[0029] Optionally, a heat-insulating and dust-proof transparent cover can be installed on the installation cabinet (detachable installation). In most cases, the control panel and the electrical box do not need to be operated, and they only need to be able to be seen. The heat-insulating and dust-proof transparent cover can reduce some heat and prevent the influence of dust in the industrial environment, further delaying the service life.

[0030] Optionally, a humidity sensor and a temperature sensor are installed inside the heat-insulating and dust-proof transparent cover. A through hole is opened on the heat-insulating and dust-proof transparent cover, which is connected to the air-conditioning system. When the humidity exceeds the set humidity, the dehumidification mode of the air-conditioning is turned on. When the temperature exceeds the set temperature, the cooling function of the air-conditioning is turned on to keep it within a reasonable humidity range and temperature range.

[0031] Through the above scheme, the control system of the diaphragm pump of the present application includes: an exhaust gas cabinet, an installation cabinet, a partition, an electrical box, a control panel and a quick connector. The electrical box, the control panel and the quick connector are all installed on the partition, the partition is installed on the installation cabinet, the control panel and the electrical box are connected to the quick connector, and a through hole is opened on the exhaust gas cabinet. The power cord, thin film silicon control line and communication network cable of the diaphragm pump are led out from the through hole and connected to the quick connector. The spacing distance between the installation cabinet and the exhaust gas cabinet reaches a preset distance, thereby isolating the influence of high temperature on the electronic control part and avoiding the influence of corrosive environment, which can solve the technical problem of short life of the electronic control part of the diaphragm pump in the related technology.

[0032] refer to Figure 1 , remove the diaphragm pump electrical box, extend each wire group in the electrical box by 2 meters (depending on the actual situation), add a 6PIN quick plug, add a partition in the empty cabinet next to the exhaust cabinet, fix the electrical box and control panel on the partition (the screen and control box can be fixed in the clean cabinet using external processing parts), connect the thin-film silicon control line and communication network cable to the control screen, and restart the diaphragm pump for test use.

[0033] This solution provides targeted improvements to the frequent downtime problem of diaphragm pumps. Without affecting the overall structure of the equipment, process environment, and production capacity loss, the diaphragm pump control box and control panel are removed, extension cords are added, and the control box and control panel are moved to a separate, clean cabinet at normal temperature. This can reduce the frequency of abnormal damage and extend the pump life to 1 year.

[0034] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
