Description

Technical Field

[0001] The utility model relates to a temperature reduction and cooling technology for an electroplating production line, in particular to an automatic temperature reduction device for an electroplating line. Background Art

[0002] In the process of chip production, there are often application scenarios where chip products need to be electroplated. The general electroplating process includes pretreatment, tinning and drying. The temperature of the drying section can generally reach 120°C. The temperature of the unloading area at the end of the drying section is also relatively high. The radiation energy to the external space causes the ambient temperature to rise, which is not conducive to employee operations. In addition, employees can easily touch the production line during transportation, causing burns or product drops. For this reason, we propose an automatic cooling device for the electroplating line to cool the unloading area at the end of the drying section, improve the working environment, and ensure product quality. Utility Model Content

One end of the high-temperature air inlet pipe is connected to the middle drying section of the drying hood. An atomizing nozzle for spraying and cooling the high-temperature air is arranged in the cooling retention cavity.

[0007] A further technical improvement of the utility model is that the air inlet of the high-temperature air inlet pipe is arranged as a flared structure and an air intake fan is installed in the flared structure to accelerate the air flow.

[0008] The further technical improvement of the utility model is that: the bottom of the atomizing nozzle is connected with a water supply branch pipe, the water supply branch pipe runs through the cooling retention cavity and is connected with the round cooling pipe, and a pressure pump is installed on the water supply branch pipe.

[0011] A further technical improvement of the utility model is that the low-temperature air outlet pipe is arranged in a U shape, and the top end of the return pipe is communicated with the lowest position of the low-temperature air outlet pipe.

DETAILED DESCRIPTION

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-3As shown, an automatic cooling device for an electroplating line comprises a base 1, a conveying line 3 is installed on the base 1 through a motor drive, and a drying cover 2 is fixed above the conveying line 3;

[0022] Specifically, the drying cover 2 includes a drying section in the middle and cooling sections 21 symmetrically arranged at both ends thereof. A meandering cooling pipe 4 is buried in the shells of the two cooling sections 21. The meandering cooling pipe 4 is provided with a water inlet and a water outlet, which are respectively connected to the external constant pressure pipeline to form a cooling circuit.

[0023] A gas cooling component is arranged inside the cooling section 21 above the meandering cooling pipe 4. The gas cooling component includes a cooling retention chamber 7. The cross section of the cooling retention chamber 7 is elliptical. A high-temperature air inlet pipe 5 is provided through the cooling retention chamber 7 on the side close to the drying section. The air inlet of the high-temperature air inlet pipe 5 is arranged in a flared structure and is provided with an air suction fan 6. A low-temperature air outlet pipe 11 is provided through the cooling retention chamber 7 on the side away from the high-temperature air inlet pipe 5.

[0024] It should be noted that the communication positions of the high-temperature air inlet pipe 5 and the low-temperature air outlet pipe 11 with the cooling retention chamber 7 are respectively located at the two sides of the bottom of the cooling retention chamber 7. In this case, since the high-temperature air has an upward trend after entering the cooling retention chamber 7, it cannot be discharged from the low-temperature air outlet pipe 11 in the first time, thereby ensuring that the high-temperature gas stays in the cooling retention chamber 7 for a long time to be fully cooled;

[0025] More specifically, a water supply branch pipe 8 is vertically installed through the bottom position of the cooling retention chamber 7, the top end of the water supply branch pipe 8 is located in the cooling retention chamber 7 and an atomizing nozzle 10 is installed at its end, the bottom end of the water supply branch pipe 8 is connected to the meander cooling pipe 4, and a pressure pump 9 is installed on the water supply branch pipe 8 to pressurize the cooling water and send it out from the atomizing nozzle 10;

[0026] The low-temperature air outlet pipe 11 is arranged in a U shape, and a return pipe 12 is arranged at the lowest position thereof, the bottom of the return pipe 12 is connected to the meander cooling pipe, and a return valve 13 is installed on the return pipe 12;

[0027] A gas confluence trough 14 is installed directly above the drying hood 2, and an exhaust square hole is provided at the top middle position of the gas confluence trough 14. The inner bottom of the trough body is provided with an inclined surface inclined downward from the middle to both sides to facilitate air condensate water to flow through the low-temperature outlet pipe 11 to the return pipe 12 and finally to the meandering cooling pipe 4.

[0028] When the utility model is in use, during the drying process, the atmosphere in the drying cover 2 is heated to a high temperature, and the cooling water circuit of the meander cooling pipe continuously cools the cooling section 21 of the drying cover 2; at the same time, the high-temperature air generated enters the cooling retention chamber 7 through the high-temperature air inlet pipe 5 under the action of the suction fan 6, and at the same time, the pressure pump 9 is in a working state, sucking and pressurizing the water flow in the meander cooling pipe 4, and then spraying it out through the atomizing nozzle, so as to cool the high-temperature air, and the air after the cooling treatment enters the gas reflux groove 14 through the low-temperature air outlet pipe 11 and is then discharged;

[0029] The cooled air condenses into water droplets upon contacting the inner wall of the low-temperature air outlet pipe 11 and the inner wall of the gas reflux groove 14 and flows back to the reflux pipe 12 . When the reflux valve 13 is opened, the refluxed water droplets re-enter the meander cooling pipe 4 .

[0030] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
