[0002] In the production of solar cells, sintering is one of the key steps, used to solidify the silver paste printed on the surface of the silicon wafer to form reliable electrical contacts. Traditional sintering machines are often designed with compressed air (CDA) directly branched from the main air source to ensure stable air pressure inside the chamber during sintering, thereby ensuring precise control of the process temperature.

[0003] However, with the above-mentioned air intake method, when the peripheral cylinders of the sintering machine, other air-consuming points, or other equipment on the production line use CDA, the total air pressure will fluctuate due to the increase in demand, which will affect the air pressure stability of each temperature zone inside the sintering machine, resulting in unstable process temperature control and affecting the quality and production efficiency of the solar cells.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] As mentioned in the background section, sintering equipment needs to maintain a stable pressure at a high threshold during operation to ensure the effectiveness of cooling in each temperature zone. However, in existing sintering equipment, the gas path design often directly branches compressed air (CDA) from the main gas source to ensure stable gas pressure inside the cavity during sintering, thereby ensuring precise control of the process temperature. However, the main gas source alone will fluctuate due to different needs, which will lead to unstable gas pressure in each temperature zone inside the sintering machine, resulting in unstable process temperature control and affecting the quality and production efficiency of the solar cells. Therefore, to address the aforementioned technical problems, the sintering equipment provided in this application includes an auxiliary pressurizing component 200 on the machine base 100. The auxiliary pressurizing component 200 is equipped with a pressure regulating chamber 210, the pressure of which is adjustable. The pressure regulating chamber 210 is connected to the air inlet 101. This allows the pressure regulating chamber 210 to provide an additional air source to the machine base. When the pressure of the total air source is unstable, the pressure in the pressure regulating chamber 210 can compensate for the internal pressure of the machine base 100, thus stabilizing the process temperature. This is beneficial for improving the quality and production efficiency of solar cells. Furthermore, due to the excessively high surface temperature of the machine tool 100, a support assembly 300 is installed on the machine tool 100 to improve its installability. At least a portion of the support assembly 300 is spaced apart from the machine tool 100. The support assembly 300 has a heat dissipation platform 310, and at least a portion of the auxiliary pressurizing assembly 200 is installed on the heat dissipation platform 310. In this way, the heat dissipation platform 310 is used to cool down the auxiliary pressurizing assembly 200, thereby avoiding the situation where the temperature of the auxiliary pressurizing assembly 200 is too high and causes safety hazards.

[0025] Please refer to Figures 1 to 4 This application provides a sintering apparatus, comprising: a machine base 100 having a gas flow path inside, an air inlet 101 on the machine base 100, the air inlet 101 being connected to the gas flow path; an auxiliary pressurizing component 200 disposed on the machine base 100, the auxiliary pressurizing component 200 having a pressure regulating chamber 210, the pressure in the pressure regulating chamber 210 being adjustable, the pressure regulating chamber 210 being connected to the air inlet 101, so that the airflow in the pressure regulating chamber 210 is introduced into the gas flow path through the air inlet 101; and a support component 300 disposed on the machine base 100, at least a portion of the support component 300 being spaced apart from the machine base 100, the support component 300 including a heat dissipation platform 310, a heat dissipation gap being provided between the heat dissipation platform 310 and the machine base 100, at least a portion of the auxiliary pressurizing component 200 being disposed on the end face of the heat dissipation platform 310 away from the machine base 100.

[0026] The sintering equipment provided in this application includes a machine base 100, an auxiliary pressurizing component 200, and a support component 300. The machine base 100 has a gas flow path and an air inlet 101 connected to the gas flow path. The auxiliary pressurizing component 200 is mounted on the machine base 100 and includes a pressure regulating chamber 210. The pressure in the pressure regulating chamber 210 is adjustable and connected to the air inlet 101, allowing the airflow in the pressure regulating chamber 210 to enter the gas flow path through the air inlet 101. The support component 300 is mounted on the machine base 100, with at least a portion spaced apart from the machine base 100. The support component 300 includes a heat dissipation platform 310, with a heat dissipation gap between the heat dissipation platform 310 and the machine base 100. At least a portion of the auxiliary pressurizing component 200 is located on the end face of the heat dissipation platform 310 furthest from the machine base 100. The pressure regulating chamber 210 can effectively reduce process temperature fluctuations caused by external air pressure fluctuations or the operation of other air-using points inside the machine, reduce dependence on high-pressure air sources, maintain temperature consistency in each temperature zone, thereby improving the controllability of the sintering process and product quality. Furthermore, the heat dissipation platform 310 is used to dissipate heat from the auxiliary pressurizing component 200, which is beneficial to the safety of the auxiliary pressurizing component 200.

[0027] Specifically, the auxiliary pressurization assembly 200 further includes: a housing 220, disposed on the heat dissipation platform 310, with a pressure regulating chamber 210 disposed within the housing 220; and a pressure regulating component 230, disposed within the housing 220, with the pressure regulating component 230 fitting against the inner wall of the housing 220. The pressure regulating chamber 210 is located between the pressure regulating component 230 and the inner wall of the housing 220. The position of the pressure regulating component 230 is movable to compress or release the air within the pressure regulating chamber 210. The pressure regulating component 230 within the housing 220 can move according to actual needs to compress or release the air within the chamber, thereby achieving dynamic and precise pressure regulation. This design can more effectively cope with changes in gas pressure requirements during sintering, ensuring the stability of process parameters and improving product quality and consistency. By precisely regulating the pressure, unnecessary air compression is reduced, lowering the load on the air compressor and thus reducing energy consumption. Simultaneously, this design avoids over-pressurization.

[0028] Preferably, the auxiliary pressurization component 200 is an air booster, and the pressure regulating chamber 210 is disposed inside the air booster. A piston is disposed inside the air booster for regulating the air pressure inside the pressure regulating chamber 210.

[0029] like Figure 2As shown, the support assembly 300 also includes: a heat sink 320, a heat dissipation platform 310 disposed on the heat sink 320, a heat dissipation section 321 disposed on the heat sink 320, and an auxiliary pressurizing assembly 200 in contact with the heat dissipation section 321 to conduct heat to the heat dissipation section 321 for heat dissipation. The close contact between the heat dissipation section 321 and the auxiliary pressurizing assembly 200 promotes rapid heat conduction and exchange, ensuring that the heat from the auxiliary pressurizing assembly 200 is quickly absorbed and dissipated by the heat sink, avoiding abnormal temperatures caused by heat accumulation. Effective heat dissipation reduces component aging and damage caused by overheating inside the equipment, extends the service life of the auxiliary pressurizing assembly 200, and reduces the frequency of replacement and maintenance.

[0030] In one embodiment provided in this application, the heat dissipation part 321 includes a plurality of heat dissipation holes 3210, which are spaced apart; and / or, the porosity of the heat dissipation plate 320 is 30% to 70%. The spaced arrangement of the plurality of heat dissipation holes 3210 can ensure that air forms effective convection inside the heat dissipation part 321, accelerating heat dissipation. The porosity of the heat dissipation plate 320 is set at 30% to 70%, which can balance structural strength and heat dissipation efficiency. A lower porosity (e.g., 30%) ensures the structural integrity and load-bearing capacity of the heat dissipation plate, while a higher porosity (e.g., 70%) greatly enhances airflow and is beneficial for rapid heat dissipation. Appropriate porosity can also reduce airflow resistance and reduce energy consumption.

[0031] In another embodiment provided in this application, such as Figure 2 and Figure 3 As shown, the support assembly 300 also includes a cooling component 330, disposed within the heat dissipation platform 310. A cooling medium circulates within the cooling component 330, and at least a portion of the auxiliary pressurizing assembly 200 is in contact with the cooling component 330. The cooling medium circulating within the cooling component 330 can quickly remove the heat generated by the auxiliary pressurizing assembly 200 during operation, effectively reducing the temperature of the pressurizing assembly. This helps maintain a stable operating environment inside the pressurizing assembly, preventing performance degradation or malfunction due to overheating. The close contact design between the cooling component 330 and the auxiliary pressurizing assembly 200 not only provides cooling but also enhances the structural stability of the entire device. Through reasonable layout and tight integration, the risk of structural deformation caused by thermal expansion and contraction is reduced, ensuring the reliability and stability of the equipment during long-term operation. Effective heat dissipation and temperature control reduce the accelerated aging of the auxiliary pressurizing assembly 200 due to excessive temperature, significantly extending the service life of the equipment.

[0032] Furthermore, the support component 300 includes a heat sink 320; the cooling component 330 includes a cooling circulation channel 331 disposed within the heat sink 320, through which a cooling medium circulates; a medium inlet 332 and a medium outlet 333 respectively disposed on the heat sink 320, with the two ends of the cooling circulation channel 331 connected to the medium inlet 332 and the medium outlet 333 respectively. The cooling circulation channel 331 allows the cooling medium to circulate within the heat sink 320, thereby exchanging heat with the auxiliary pressurizing component 200 during the circulation process and removing heat from the surface of the auxiliary pressurizing component 200; the cooling medium enters through the medium inlet 332, passes through the cooling circulation channel 331, and then flows out from the medium outlet 333, forming a circulation loop, thereby continuously cooling the auxiliary pressurizing component 200 and preventing the temperature of the auxiliary pressurizing component 200 from becoming too high.

[0033] In practice, the cooling circulation channel 331 extends along a curved trajectory. This curved trajectory increases the surface area of ​​contact between the fluid and the equipment, thereby improving heat exchange efficiency. Compared to straight channels, curved channels allow the fluid to exchange heat with the equipment surface over a longer path, increasing heat exchange efficiency, effectively removing more heat, and accelerating the cooling process. The curved design also helps the fluid form a more stable flow state within the channel, reducing turbulence and cavitation, ensuring uniform coolant distribution, and preventing localized overheating.

[0034] In the embodiments provided in this application, such as Figure 4 As shown, the support assembly 300 further includes: support legs 340 connected to the heat sink 320. The support legs 340 are mounted on the machine base 100 to support the heat sink 320. There are at least two support legs 340, which are spaced apart along the length of the heat sink 320. The support legs 340 and the heat sink 320 are integrally formed. The integrally formed support legs 340 and the heat sink 320 form a seamless connection. Compared with welding or bolted connections, this design reduces stress concentration at the connection points, improves the strength and stability of the overall structure, and ensures the safety and reliability of the auxiliary pressurization assembly 200 during operation.

[0035] At least a portion of the support foot 340 is resiliently configured. The resilient support foot 340 effectively absorbs vibrations and shocks during the sintering process, reducing component wear and noise levels caused by vibration during equipment operation, and improving equipment stability and service life. The resilient material typically possesses good thermal stability and low thermal conductivity, which helps isolate the heat generated by the sintering equipment, reducing its impact on the support structure, maintaining the temperature stability of the support components, and preventing structural deformation caused by thermal expansion and contraction. The resiliently designed support foot can automatically adjust its deformation according to the weight and pressure distribution of the equipment, ensuring the balance of the equipment under different operating conditions, reducing equipment tilting problems caused by uneven ground or load changes, and improving the controllability of the process.

[0036] Preferably, the support foot 340 is made of silicone or composite material (such as carbon fiber or glass fiber). The elastic support foot can be designed as a hollow structure, filled with air or other gases to improve its elastic deformation capacity and adjustment range, while reducing weight.

[0037] The sintering equipment also includes a control valve 400, located at the air inlet 101. The control valve 400 is connected to both the air inlet 101 and the pressure regulating chamber 210. Located at the air inlet 101, the control valve 400 directly controls the airflow entering the pressure regulating chamber. Through precise adjustment, the air pressure within the chamber can be kept stable within the required range. The control valve 400 can quickly respond to changes in air pressure and adjust the airflow in a timely manner. When abnormal pressure is detected, it can automatically shut off or adjust the airflow to prevent overpressure or underpressure, thus increasing the safety of the sintering equipment.

[0038] In the sintering equipment of this application, a heat sink is installed on the machine base 100, and a pressurized air tank, i.e., an air booster, is installed above the heat sink. The working principle of the pressurized air tank is as follows:

[0039] a. Its working principle is mainly based on the principle of air pressure amplification, which increases the pressure by increasing the volume of air;

[0040] b. Pressure amplification principle: The air booster drives the high-pressure gas at the small-area piston end through the low-pressure gas at the large-area piston end. The boost ratio, which is the ratio of piston areas, determines the output pressure.

[0041] c. Working process: When the piston at the drive end moves backward, it draws in the pressurized gas, and the one-way valve at the high-pressure end closes; when the drive piston moves forward, the small piston at the high-pressure end also moves forward, the high-pressure outlet opens, the inlet one-way valve closes, and the high-pressure gas is output from the outlet.

[0042] d. Advantages: Air boosters have advantages such as small size and easy portability, no sparks and can be used in explosive environments, no power supply and low energy consumption, simple operation and convenient maintenance, fewer seals and no oil lubrication.

[0043] Furthermore, the power CDA is connected to the air tank; then the air tank is used to connect to the air circuits of each zone.

[0044] Adding an air booster to the sintering process can prevent instability in process temperature caused by air pressure fluctuations in the surrounding environment, machine cylinders, and other air-consuming points, thus effectively improving the stability of process temperature.

[0045] In practical applications, a pressure sensor is installed inside the machine tool 100 to detect the air pressure in the internal air circuit in real time. The control valve 400 is connected to the pressure sensor signal, and the pressure sensor transmits data to the control system in real time. When the detected air pressure is lower than the target value, the control system commands the control valve 400 to increase its opening, increasing the air intake to quickly raise the air pressure. Conversely, if the air pressure is higher than the target value, the control system will instruct the control valve 400 to decrease its opening, limiting the air intake and lowering the air pressure. In this way, when the pressure sensor detects that the air pressure deviates from the predetermined range, the control valve 400 can automatically adjust the air intake, quickly correct the air pressure deviation, and maintain the pressure in a stable state.

[0046] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0047] The sintering equipment provided in this application includes a machine base 100, an auxiliary pressurizing component 200, and a support component 300. The machine base 100 is provided with an air inlet 101. The auxiliary pressurizing component 200 is disposed on the machine base 100 and is provided with a pressure regulating chamber 210. The pressure in the pressure regulating chamber 210 is adjustable and is connected to the air inlet 101. The support component 300 is disposed on the machine base 100, and at least a portion of the support component 300 is spaced apart from the machine base 100. The support component 300 includes a heat dissipation platform 310, and at least a portion of the auxiliary pressurizing component 200 is disposed on the heat dissipation platform 310. The pressure regulating chamber 210 can effectively reduce process temperature fluctuations caused by external air pressure fluctuations or the operation of other air-using points inside the machine, reduce dependence on high-pressure air sources, maintain temperature consistency in each temperature zone, thereby improving the controllability of the sintering process and product quality. Furthermore, the heat dissipation platform 310 is used to dissipate heat from the auxiliary pressurizing component 200, which is beneficial to the safety of the auxiliary pressurizing component 200.
