Description

Technical Field

[0001] This utility model relates to the field of copper strip tin plating pilot technology, specifically a drying and heating unit of a copper strip tin plating pilot device. Background Technology

[0002] In the pilot-scale tin plating process of copper strip, the drying of flux on the surface of the copper strip and the preheating of the copper strip are key steps affecting the quality of tin plating.

[0003] In the existing technology, the drying and heating unit of the copper strip tin plating pilot plant has the following problems: traditional heating devices lack effective heat preservation structures, and heat is easily lost through air convection and radiation during the heating process, resulting in low thermal efficiency and increased energy consumption; traditional drying and preheating devices mostly adopt a linear layout, and the overall space occupied by the equipment is large, especially in pilot-scale scenarios where laboratory space is limited, making it difficult to meet the requirements of compact layout. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a drying and heating unit for a copper strip tin plating pilot device, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model discloses a drying and heating unit for a copper strip tin plating pilot plant. The technical solution adopted includes a mounting plate and a chamber shell. The chamber shell is provided on the mounting plate, and the chamber shell and the mounting plate enclose a chamber with a transparent bottom. The cabin is equipped with a heating unit for the copper strip. There are two sets of the heating unit, and the two sets of the heating unit have the same structure and are arranged in an inverted "V" shape on the mounting plate. The mounting plate is also equipped with a steering component that changes the conveying direction of the copper strip. After the copper strip is dried and preheated by the first group of heating units, it is turned by the steering component and enters the second group of heating units. While ensuring the drying and preheating effect, the horizontal space occupied by the equipment is greatly reduced, which is more suitable for the compact layout requirements of pilot-scale scenarios.

[0006] As a preferred technical solution of this utility model, the heating unit includes a heating tube and a heating element. The heating tube is mounted on the mounting plate, and the copper strip passes through the inside of the heating tube. The heating element is provided on the outer wall of the heating tube, and the heating element is covered with an insulation layer. By covering the heating element with a ceramic fiber cotton insulation layer, heat loss through radiation and convection can be effectively reduced. At the same time, the structural design of the spiral quartz heating tube increases the heating area, improves heat transfer efficiency, and reduces energy consumption.

[0007] As a preferred technical solution of this utility model, the heating tube is mounted on the mounting plate by a fixing member. The fixing member is a U-shaped pipe clamp, and there are two sets of the fixing members. The two sets of fixing members are used to fix the two ends of the heating tube respectively.

[0008] As a preferred embodiment of this utility model, the heating element is an electric heating wire; the insulation layer is made of ceramic fiber cotton.

[0009] As a preferred embodiment of the present invention, the steering assembly includes a steering roller, which is rotatably connected to the mounting plate, and the contact surface between the steering roller and the copper strip is provided with a ceramic coating.

[0010] As a preferred technical solution of this utility model, the mounting plate is also provided with a thermal resistor. The detection end of the thermal resistor is located inside the heating tube of the heating unit. The thermal resistor is used to monitor the temperature inside the heating tube in real time. Combined with the external PLC control center, the temperature can be accurately controlled within ±2℃ to ensure that the flux is completely dried and the copper strip reaches the optimal preheating temperature, thereby improving the quality of the tin plating layer.

[0011] As a preferred embodiment of the present invention, the hull includes a cabin body and a hatch, the cabin body is mounted on the mounting plate, and the hatch body is hinged with a double-opening type.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by wrapping the heating element with a ceramic fiber cotton insulation layer, this utility model can effectively reduce heat loss through radiation and convection. At the same time, the structural design of the spiral quartz heating tube increases the heating area, improves heat transfer efficiency, and reduces energy consumption.

[0013] The two heating units are arranged in an inverted "V" shape, and with the top turning roller, the horizontal space occupied by the equipment is greatly reduced while ensuring the drying and preheating effect. At the same time, the segmented heating is more thorough and more suitable for the compact layout requirements of pilot-scale scenarios.

[0014] The cabinet-style opening and closing mechanism not only achieves heat preservation but also facilitates the maintenance of internal components by staff; the absence of heating components at the steering rollers helps protect their thermal stability. Attached Figure Description

There are two sets of heating units. The two sets of heating units have the same structure and are arranged in an inverted "V" shape on the mounting plate 1. The cabin includes a body 2 and a door 3. The body 2 is mounted on the mounting plate 1, and the body 2 is hinged with a double-opening door 3, which facilitates the opening of the door 3 by the staff to install the copper strip 4.

[0019] The mounting plate 1 is also provided with a steering assembly to change the conveying direction of the copper strip 4. After the copper strip 4 is dried and preheated by the first group of heating units, it is turned by the steering assembly and enters the second group of heating units. The inverted "V" shaped top has an opening that can dissipate heat accumulated at the steering assembly in a timely manner, preventing thermal deformation due to high temperature, reducing equipment failure, and extending service life.

[0020] like Figure 3 and Figure 4 As shown, the heating unit includes a heating tube 10 and a heating element 9. The heating tube 10 is mounted on the mounting plate 1. The copper strip 4 passes through the interior of the heating tube 10. The heating element 9 is provided on the outer wall of the heating tube 10. The heating element 9 is covered with a heat insulation layer 6. The heating element 9 is an electric heating wire. The heat insulation layer 6 is ceramic fiber cotton.

[0021] The heating tube 10 is mounted on the mounting plate 1 by means of fasteners 5. The fasteners 5 are U-shaped pipe clamps and there are two sets of them. The two sets of fasteners 5 are used to fix the two ends of the heating tube 10 respectively.

[0024] The working principle of this utility model: The copper strip 4, after being treated with flux, enters from the bottom of the compartment and first passes through the heating tube 10 of the heating unit; the heating element 9 on the outer wall of the heating tube 10 is energized and heats up, and the heat is transferred to the copper strip 4 through the heating tube 10 to dry the flux on the surface of the copper strip 4; the ceramic fiber cotton insulation layer 6 outside the heating element 9 reduces heat loss to the outside and improves heat utilization efficiency. The copper strip 4, after drying and preheating, is conveyed upwards and changes direction via the top turning roller 8 (the ceramic coating on the surface of the turning roller 8 is heat-resistant, increasing the service life of the turning roller 8 and reducing damage to the flux on the surface of the copper strip 4); the copper strip 4 after turning is inserted into the heating tube 10 of the preheating unit, and is further heated under the action of the heating tube 10 to reach the preheating temperature required for tin plating. The detection end of the thermal resistor 7 monitors the temperature inside the heating tube 10 of the heating unit in real time and transmits the temperature signal to the external PLC control center. The PLC control center adjusts the heating power of the heating element 9 according to the difference between the preset temperature and the actual monitored temperature to achieve precise temperature control (±2℃) and ensure stable drying and preheating effects.
