Description

Technical Field

[0001] This invention relates to the field of tin plating equipment technology, and in particular to a tin plating equipment and method for the surface of magnesium-copper alloy stranded conductors. Background Technology

[0002] Tin plating and its alloys are coatings with good solderability and a certain degree of corrosion resistance, and are widely used in electronic components and printed circuit boards. In addition to physical methods such as hot dipping and spraying, electroplating, immersion plating, and chemical plating are widely used in industry due to their simplicity and ease of implementation.

[0003] Currently, patent document CN109811182B discloses a method for preparing a high-strength, high-conductivity copper alloy stranded conductor for aerospace applications. The alloy material is prepared from elemental copper, elemental chromium, a 30% copper-zirconium alloy, and a 30% copper-cadmium alloy as raw materials, through key steps including vacuum induction melting, continuous casting, homogenization treatment, solution treatment, cold drawing, aging treatment, cold drawing again, and single-wire annealing. The alloy material composition (wt%) is: Cr 0.3–0.5%; Cd 0.2–0.4%; Zr 0.01–0.04%; Cu balance. The resulting alloy material has a stranded conductor with a diameter of 19 / 0.127, a strand length of 0.59 ± 0.02 mm, a maximum weight ≤ 2.1 g / m, a breaking force ≥ 102 N, and a maximum DC resistance ≤ 88 Ω / km at 20℃.

[0004] In practical applications, it has been found that when tinning the surface of magnesium-copper alloy stranded conductors, the conductors need to be transported and pass through the tinning process. However, if dust adheres to the conductors during transport and is not cleaned, the tinning quality will be affected. Therefore, we propose a tinning device and method for magnesium-copper alloy stranded conductors to solve the above problems. Summary of the Invention

[0010] A rotary motor is fixedly installed on the top of the housing. A drive shaft is fixedly installed on the output shaft of the rotary motor. A blower fan blade is fixedly installed on the bottom end of the drive shaft. A fixed plate is provided inside the housing. A connecting mechanism is provided between the fixed plate and the housing.

The connecting seat is fixedly installed on the top inner wall of the housing, the adjusting groove is opened on the bottom of the connecting seat, the adjusting seat is slidably installed in the adjusting groove, and the bottom of the adjusting seat is fixedly installed on the fixed plate.

[0012] Preferably, a drive hole is provided on one inner wall of the adjustment groove, and the same drive seat is slidably installed in the two drive holes, and the drive seat is fixedly connected to the adjustment seat.

[0013] Preferably, a reinforcing plate is fixedly installed between the two connecting seats, a drive screw is rotatably installed on the top of the reinforcing plate, the top end of the drive screw is rotatably installed on the top inner wall of the housing, and the drive seat is threaded onto the drive screw.

[0014] Preferably, a drive motor is fixedly installed on the top of the housing, and the output shaft of the drive motor is fixedly connected to the corresponding drive screw.

[0015] Preferably, a horizontal plate is fixedly installed on one side of the partition, and a striking mechanism for striking magnesium-copper alloy stranded conductors is connected to the horizontal plate.

[0016] Preferably, the striking mechanism includes a rectangular hole, a rectangular rod, a U-shaped plate, a rubber roller, a pressure plate, and a return spring. The rectangular hole is formed on the horizontal plate, and the rectangular rod is slidably installed inside the rectangular hole. The bottom ends of the two rectangular rods are fixedly installed with a U-shaped plate, and the inner walls on both sides of the U-shaped plate are fixedly installed with rubber rollers. The top ends of the two rectangular rods are fixedly installed with the same pressure plate, and the bottom of the pressure plate is fixedly installed with multiple return springs. The bottom ends of the return springs are fixedly installed on the horizontal plate.

[0017] Preferably, a vertical plate is fixedly installed on the top inner wall of the housing, and a drive shaft is rotatably installed on the vertical plate. An eccentric wheel is fixedly installed at one end of the drive shaft, and the eccentric wheel is in contact with the pressure plate. A worm is fixedly installed at the other end of the drive shaft, and a worm is fixedly installed on the drive shaft, and the worm meshes with a worm wheel.

[0018] Preferably, the filtration assembly includes a coarse filter, an activated carbon layer, and a fine filter, with the activated carbon layer disposed on top of the fine filter and the coarse filter disposed on top of the activated carbon layer.

[0019] A tin plating method for a magnesium-copper alloy stranded conductor surface tin plating equipment includes the following steps:

[0020] S1: The magnesium-copper alloy stranded conductor passes through the housing through guide hole one and guide hole two. Multiple guide rollers guide the magnesium-copper alloy stranded conductor. By starting the drive motor, the drive motor drives the drive screw to rotate through the output shaft. The drive screw drives the drive seat and the adjusting seat to move downward. The adjusting seat drives the fixed plate to move downward. The fixed plate drives the pressure roller to move downward through the drive rod. The pressure roller squeezes the magnesium-copper alloy stranded conductor downward, so that the magnesium-copper alloy stranded conductor can be inserted into the tin plating box, thereby achieving the purpose of tin plating the magnesium-copper alloy stranded conductor.

[0021] S2: When the magnesium-copper alloy stranded conductor is conveyed in the box, the water pump can draw water from the water tank and spray it out through the spray pipe to clean the magnesium-copper alloy stranded conductor. The cleaned water flows back to the water tank through the filter assembly, which can achieve the purpose of water recycling.

[0022] S3: By starting the rotary motor, the rotary motor can drive the drive shaft and the blower fan blades to rotate through the output shaft. The blower fan blades can blow air onto the cleaned magnesium-copper alloy stranded conductor, so that the water droplets on the magnesium-copper alloy stranded conductor are blown off and dried, thus avoiding the situation where water on the magnesium-copper alloy stranded conductor affects the tin plating quality.

[0023] S4: Through the cooperation of the worm gear and worm wheel, the rotation of the drive shaft can drive the transmission shaft to rotate, which in turn drives the eccentric wheel to rotate. The eccentric wheel can press the pressure plate downwards, and the pressure plate can compress the return spring. After the eccentric wheel rotates one revolution, it stops pressing the pressure plate, and the return spring pushes the pressure plate to return to its original position. As the eccentric wheel rotates continuously, the pressure plate can move up and down reciprocally. The pressure plate moves up and down reciprocally through the rectangular rod, U-shaped plate, and rubber roller. The rubber roller can tap the magnesium-copper alloy stranded conductor, which can shake off the water droplets on the magnesium-copper alloy stranded conductor, thereby cleaning and removing dust from the magnesium-copper alloy stranded conductor. At the same time, it can treat the water droplets remaining on the magnesium-copper alloy stranded conductor, thereby improving the tin plating quality of the magnesium-copper alloy stranded conductor.

[0024] The beneficial effects of this invention are:

[0025] 1. The magnesium-copper alloy stranded conductor is passed through the box. Multiple guide rollers guide the magnesium-copper alloy stranded conductor. The pressure roller moves downward and squeezes the magnesium-copper alloy stranded conductor downward, so that the magnesium-copper alloy stranded conductor can be inserted into the tin plating box, thereby achieving the purpose of tin plating the magnesium-copper alloy stranded conductor.

[0026] 2. When the magnesium-copper alloy stranded conductor is conveyed in the box, the water pump can draw water from the water tank and spray it out through the spray pipe to clean the magnesium-copper alloy stranded conductor. The cleaned water flows back to the water tank through the filter assembly, which can achieve the purpose of water recycling.

[0027] 3. Through the cooperation of the rotating motor, drive shaft and blower blades, the blower blades blow air downwards to blow the cleaned magnesium-copper alloy stranded conductor, so that the water droplets on the magnesium-copper alloy stranded conductor are blown off and dried, thus avoiding the situation where water on the magnesium-copper alloy stranded conductor affects the tin plating quality.

[0028] 4. Through the cooperation of the drive shaft and eccentric wheel, when the eccentric wheel rotates continuously, the pressure plate, rectangular rod, U-shaped plate and rubber roller can move up and down reciprocally. The rubber roller can knock the magnesium-copper alloy stranded conductor, which can shake off the water droplets on the magnesium-copper alloy stranded conductor, thereby cleaning and removing dust from the magnesium-copper alloy stranded conductor. At the same time, it can treat the water droplets remaining on the magnesium-copper alloy stranded conductor, thereby improving the tin plating quality of the magnesium-copper alloy stranded conductor.

S4: Through the cooperation of the worm (28) and worm wheel (27), the rotation of the drive shaft (15) can drive the transmission shaft (25) to rotate, the transmission shaft (25) can drive the eccentric wheel (26) to rotate, the eccentric wheel (26) can press the pressure plate (21) downward, the pressure plate (21) can compress the return spring (23), when the eccentric wheel (26) rotates one revolution, at this time the eccentric wheel (26) does not press the pressure plate (21), the return spring (23) can push the pressure plate (21) to return to its original position, when the eccentric wheel (26) rotates one revolution, ... can drive the transmission shaft (25) to rotate, the transmission shaft (25) can drive the eccentric wheel (26) to rotate, the transmission shaft (25) can drive the eccentric wheel (26) to rotate, the transmission shaft (25) can drive the eccentric wheel (26) to rotate, the transmission shaft (26) can drive the eccentric wheel (26) to rotate, the transmission shaft (27) can drive the eccentric wheel (26) to rotate, the transmission shaft (26) can drive the eccentric wheel (26) to rotate, the transmission shaft (27) can drive the eccentric wheel (26) to rotate, the transmission shaft (26) can drive the eccentric wheel (26) to rotate, the transmission shaft (27) can drive the eccentric wheel (26) to rotate, the transmission shaft (26) can drive the When the wheel (26) rotates continuously, the pressure plate (21) can move up and down repeatedly. The pressure plate (21) moves up and down repeatedly through the rectangular rod (20), the U-shaped plate (22) and the rubber roller (17). The rubber roller (17) can knock the magnesium-copper alloy stranded conductor, which can shake off the water droplets on the magnesium-copper alloy stranded conductor, thereby cleaning and removing dust from the magnesium-copper alloy stranded conductor. At the same time, it can treat the water droplets remaining on the magnesium-copper alloy stranded conductor, thereby improving the tin plating quality of the magnesium-copper alloy stranded conductor.
