The device is convenient for adjusting the ends of the wire harness to position and tin during tinning, and the tinning operation is more precise, thereby improving the accuracy and qualified rate of the tinning mechanism body during tinning of the wire harness.

[0003] According to a multifunctional tinning machine disclosed in the authorized patent application No. 201822019460.5, the existing tinning structure directly passes the processed wire harness through the transmission pipe into the inside of the tinning channel during the tinning process of the wire harness processing and production, and stops the wire harness at the tin spray port for tinning. It is inconvenient to position and press the wire harness during the tinning operation. When the end of the wire harness is exposed to the outside world and is touched during tinning, it is easy to cause the wire harness to be unstable. The unstable wire harness during tinning is easy to cause displacement during tinning, and the position of the tinning changes, resulting in unqualified tinning, thereby affecting the accuracy of the tinning structure during the tinning process of the wire harness processing and production.

After heating, tin is sprayed from the tin spraying port 109 to the tinning position on the surface of the wiring harness. The tin spraying is collected by the collecting box 106, and thus the wiring harness is tinned once through the tinning mechanism body 100. The tinning mechanism body 100 is also provided with:

[0024] A convenient adjustment and positioning mechanism is provided, and the convenient adjustment and positioning mechanism includes a driving assembly arranged at both ends of the base 101, a downward adjustment and positioning assembly is provided at the end of the driving assembly, and a control assembly is provided at both ends of the downward adjustment and positioning assembly.

[0025] In order to facilitate the movement and adjustment operation of the movable adjustment frame 1033 through the driving component, in this embodiment, preferably, the driving component includes an adjustment slot 1032 opened at both ends inside the base 101, and a screw rod 1034 rotates inside the adjustment slot 1032. The top of the screw rod 1034 is located on the upper surface of the base 101 and a forward and reverse motor 1031 is installed.

[0028] A heat insulation protection mechanism is provided, and the heat insulation protection mechanism includes a heat insulation protection component arranged on the outer surface of the tin adding cylinder 104. A fixed installation component is provided at the end of the heat insulation protection component. When the tinning mechanism main body 100 is in use, heat is generated on the outer surface of the tinning cylinder 104. The heat insulation protection mechanism provides heat insulation protection for the outer surface of the tinning cylinder 104, which is less likely to cause danger and improves the heat insulation protection effect of the tinning mechanism main body 100 on the outer surface of the tinning cylinder 104 during the wire harness tinning operation.

[0029] In order to facilitate the thermal insulation protection of the outer surface of the tin adding cylinder 104 through the thermal insulation protection component, and to prevent the outer surface of the tin adding cylinder 104 from being heated and exposed to the outside world and causing danger, in this embodiment, preferably, the thermal insulation protection component includes an outer protective tube 1041 arranged on the outer surface of the tin adding cylinder 104, and a thermal insulation cavity 1044 is formed at the connection between the outer protective tube 1041 and the outer surface of the tin adding cylinder 104. When the tin adding cylinder 104 is heated, the thermal insulation cavity 1044 can insulate the outer protective tube 1041, and the thermal insulation cavity 1044 and the outer protective tube 1041 can be used to thermally protect it.

[0030] In order to facilitate the outer casing 1041 to be closed on the outer surface of the tin adding cylinder 104 and fixedly installed after being fixedly installed by fixing the installation component, in this embodiment, preferably, the fixed installation component includes a lower card groove 1045 opened at the bottom end of the tin adding cylinder 104 and located on the upper surface of the base 101. After the outer casing 1041 is closed on the outer surface of the tin adding cylinder 104, the bottom end of the outer casing 1041 is engaged with the inside of the lower card groove 1045. The top of the outer casing 1041 is integrally formed with a transmission pipe 102, and a fixing bolt 1043 is rotated at the edge of the mounting ring 1042. An internal threaded hole 1046 is opened at the top edge of the tin adding cylinder 104. The end of the fixing bolt 1043 is consistent with the internal structure of the internal threaded hole 1046. The fixing bolt 1043 is rotated again to embed into the inside of the internal threaded hole 1046 to fix the mounting ring 1042, thereby fixing the top end of the outer casing 1041 to the top end of the tin adding cylinder 104, which is convenient for fixing and protecting the outer casing 1041.

[0031] The working principle and use process of the present invention are as follows: before using the adjustable wire harness tinning structure, the tinning mechanism body 100 is first placed in a certain position and fixedly installed through the base 101. After the tinning mechanism body 100 is installed and during the tinning process, the tin adding cylinder 104 is heated by the electric heating tube 107, and the feed port 105 feeds the material into the interior of the tin adding cavity 108 and heats and melts it into tin water. The processed wire harness is again passed through the transmission pipe 102 to the interior of the tinning channel 103, and again enters the wire harness terminal from the other end of the tinning channel 103 until the end of the wire harness and the terminal are closed in the tinning position on the lower surface of the tin spraying port 109. After heating, tin is sprayed from the tin spraying port 109 to the tinning position on the surface of the wire harness. The sprayed tin is collected by the collection box 106, and thus a tinning operation of the wire harness is completed once through the tinning mechanism body 100.

[0032] Then, before the tinning mechanism main body 100 is used, the outer casing 1041 is closed on the outer surface of the tinning cylinder 104 until the bottom end is engaged with the inside of the lower card slot 1045, the mounting ring 1042 is closed at the top edge of the tinning cylinder 104, and the rotating fixing bolt 1043 is inserted into the inside of the internal threaded hole 1046 to fix the outer casing 1041, thereby fixing the outer casing 1041 to the surface of the tinning cylinder 104 to form a heat insulation cavity 1044, and when the tinning mechanism main body 100 is used for a long time and the outer surface of the tinning cylinder 104 is heated, it is convenient to insulate and protect it from heat by the heat insulation cavity 1044 and the outer casing 1041, and it is not easy to expose the outer surface of the tinning cylinder 104 directly to the outside world and cause danger of overheating, thereby improving the heat insulation protection effect of the tinning mechanism main body 100 on the outer surface of the tinning cylinder 104 during the wiring harness tinning operation;

[0033] When the tinning mechanism body 100 is tinning the wiring harness, the wiring harness and the terminal enter the interior of the tinning channel 103 for tinning, and the forward and reverse motors 1031 are operated to drive the screw rod 1034 to rotate. The screw rod 1034 rotates to move the movable adjustment frame 1033 on the outer surface of the screw rod 1034. When the movable adjustment frame 1033 moves, the limit block 1036 slides within the internal limit groove 1035, thereby moving the movable adjustment frame 1033 to drive the lower pressure plate 1037 to move downward and adjust to the surface of the wiring harness to be tightly pressed and fixed, so that the wiring harness is positioned and fixed before tinning, and the terminal at the end of the wiring harness is again entered into the interior of the tinning channel 103 from the other end of the tinning channel 103 for re-positioning and fixing. Therefore, it is convenient to position and press the wiring harness for tinning, and it is not easy to touch the wiring harness and deflect during tinning. The tinning is more accurate after positioning, which improves the accuracy and qualified rate of the tinning mechanism body 100 during tinning of the wiring harness.
