Description

Technical Field

[0001] The invention relates to the technical field of tinning equipment, and in particular to a tinning equipment and a tinning method for the surface of a magnesium-copper alloy stranded conductor. Background Art

[0002] Tin plating and its alloys are coatings with good solderability and certain corrosion resistance, and are widely used in electronic components and printed circuit boards. In addition to physical methods such as hot dipping and spraying, the preparation of tin layers has been widely used in industry due to its simplicity, such as electroplating, immersion plating and chemical plating.

[0003] At present, the patent document with the authorization announcement number CN109811182B discloses a method for preparing a high-strength and high-conductivity copper alloy stranded conductor for aerospace. The alloy material is made of single copper, single chromium, copper-zirconium 30% and copper-cadmium 30% intermediate alloy as raw materials, and is obtained through key steps such as vacuum induction melting, down-drawing continuous casting, homogenization treatment, solution treatment, cold drawing, aging treatment, cold drawing and single wire annealing treatment. Among them, the alloy material ratio is (wt%): Cr0.3-0.5%; Cd0.2-0.4%; Zr0.01-0.04%; Cu balance. The obtained alloy material stranded conductor is 19 / 0.127, with a stranding outer diameter of 0.59±0.02mm, a maximum weight ≤2.1g / m, a tensile force ≥102N, and a maximum DC resistance ≤88Ω / km at 20℃.

The drive motor (38) is started, and the drive motor (38) is driven to rotate the drive screw (37) through the output shaft, and the drive screw (37) is driven to move the drive seat (35) and the adjustment seat (31) downward, and the adjustment seat (31) is driven to move the fixed plate (32) downward, and the fixed plate (32) is driven to move the pressure roller (8) downward through the drive rod (33), and the pressure roller (8) is driven to press the magnesium-copper alloy stranded conductor downward, so that the magnesium-copper alloy stranded conductor can be inserted into the tinning box (7), thereby achieving the purpose of tinning the magnesium-copper alloy stranded conductor; S2: When the magnesium-copper alloy stranded conductor is transported in the box (1), the water pump (11) can extract water from the water tank (9) and spray it out through the spray pipe (13), so as to clean the magnesium-copper alloy stranded conductor. The cleaned water flows back into the water tank (9) through the filter assembly (10), so as to achieve the purpose of recycling water. S3: By starting the rotating motor (14), the rotating motor (14) can drive the driving shaft (15) and the blower blades (16) to rotate through the output shaft, and the blower blades (16) can blow air to the cleaned magnesium-copper alloy stranded conductor, so that the water droplets on the magnesium-copper alloy stranded conductor are blown off and dried, thereby avoiding the situation where the magnesium-copper alloy stranded conductor has water on it and affects the tinning quality; S4: Through the cooperation of the worm (28) and the worm wheel (27), the rotation of the drive shaft (15) can drive the transmission shaft (25) to rotate, and the transmission shaft (25) can drive the eccentric wheel (26) to rotate, and the eccentric wheel (26) can press the pressure plate (21) downward, and the pressure plate (21) can compress the reset spring (23). When the eccentric wheel (26) rotates one circle, the eccentric wheel (26) does not press the pressure plate (21), and the reset spring (23) can push the pressure plate (21) to reset. When the wheel (26) rotates continuously, the pressing plate (21) can be reciprocated up and down. The pressing plate (21) is reciprocated up and down 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 and 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, the water droplets remaining on the magnesium-copper alloy stranded conductor can be processed, thereby improving the tinning quality of the magnesium-copper alloy stranded conductor.
