Description

Technical Field

[0001] The invention relates to the technical field of lead plating devices, in particular to a lead plating device and a lead plating method for a wiring harness terminal. Background Art

[0002] Now with the development of society, people are paying more and more attention to safety issues in life. For example, car safety. Most cars are now controlled by on-board computers. The on-board computer is equivalent to the brain of the vehicle. Information transmission needs to be executed through various wiring harnesses. The wiring harness is equivalent to the nerves of the human body. It is a terrible thing if the wiring harness fails. The quality of the connection between the wiring harness and the terminal block directly reflects the quality of the wiring harness. The current connection method between the wiring harness and the terminal block is generally to use the deformation of the terminal block itself to clamp the wire to achieve the purpose of connecting the two. However, such a connection is not very good in terms of connection compliance. When encountering a sudden large current, an arc will appear. The arc can easily cause the vehicle to spontaneously combust due to its high temperature characteristics. In order to solve this problem, lead plating will be performed on the wiring harness terminal block;

[0003] In the prior art, when the terminal is electroplated, the residue attached to its surface will affect the electroplating effect.

10. A lead plating method for a wiring harness terminal, characterized in that: The following steps are involved: S1: First, the water inlet hose (8) is connected to the external water supply pipeline through the connecting flange (9). After the connection, the wiring harness terminal to be electroplated is placed in the release agent for soaking. After soaking, the residue on the surface is removed. After removal, it is placed in the storage net barrel (33). After storage, the two electric telescopic rods (31) are started to make the storage net barrel (33) move downward into the water storage barrel (71). Then, the external water is injected into the annular tube (72) through the water inlet hose (8). The water entering the annular tube (72) is sprayed into the storage net barrel (33) through the two nozzles (74) on the end surfaces of the two L-shaped nozzles (73) to rinse the terminals inside. S2: during the flushing process, the second motor (61) is started to rotate the second gear (62) and drive the gear ring (63) to rotate, the gear ring (63) rotates and drives the rotating shaft (51) to rotate, the rotating shaft (51) rotates and drives the three connecting rods (52) to move, the three connecting rods (52) move and drive the three first gears (55) to move, during the movement of the three first gears (55), the three connecting rods (52) can be rotated under the action of the gear ring (56), the three connecting rods (52) rotate and drive all the bristles (54) to rotate to wipe the terminal and remove the mold release agent remaining on the surface; S3: After the release agent is removed, the heater (41) is started, and the hot air generated enters the interior of the air guide pipe (43) through the air outlet pipe (42). The hot air entering the interior of the air guide pipe (43) is sprayed toward all the cleaned terminals through all the spray pipes (45) to dry them; S4: After drying, the electroplating liquid is injected into the storage tank (12). After injection, the two electric telescopic rods (31) are controlled to retract so that the storage net barrel (33) returns to its original position. Then, the first motor (22) is started to rotate the threaded rod (24). The threaded rod (24) rotates to drive the moving frame (23) to move. The moving frame (23) moves to drive the storage net barrel (33). When the storage net barrel (33) moves to a position corresponding to the storage tank (12), the two electric telescopic rods (31) are controlled to work again so that the storage net barrel (33) moves downward into the storage tank (12). S5: After the storage net barrel (33) enters the storage tank (12), the lead block (13) is powered by the storage battery (17). After the power is supplied, the lead wire terminals inside the storage net barrel (33) can be plated with lead in combination with the electroplating solution inside the storage tank (12); S6: After lead plating, the two electric telescopic rods (31) are controlled to contract so that the storage net barrel (33) moves upward to the outside of the storage tank (12), and then all the connecting rods (52) are controlled to rotate to move all the wiring harness terminals. During the moving process, the heater (41) is restarted to spray hot air through the evenly distributed air jets (45) to the electroplated wiring harness terminals, so as to dry them. After drying, they can be convenient for subsequent use.
