Description

Technical Field

[0001] The utility model relates to the technical field of wire processing, and particularly relates to a wire core tin dipping structure. Background Art

[0002] In an intelligent plug assembly device, it can cut a wire coil into a set length, strip both ends of the wire, and finally dip the wire ends into tin liquid and then assemble the terminals.

[0003] After the wire is stripped, it is immediately twisted and dipped with a soldering flux, and then the tin dipping process is carried out. The existing tin dipping process is to hold a clamping tool manually and then immerse the stripped end of the wire into a heated tin furnace for a period of time. In this process, it completely relies on manual immersion, with a large labor intensity, and the dipping depth is controlled manually, making it difficult to form the uniformity of the tin dipping height, which affects the processing quality of the wire.

[0007] The jig plate pushing component includes an inclined pushing cylinder and an inclined pushing plate fixed to the piston rod end of the inclined pushing cylinder; the inclined pushing plate is arranged facing the wire clamping jig plate.

[0008] Furthermore, the jig plate pushing component further includes a positive pressure positioning module; the positive pressure positioning module includes a downward pressing jig positioning cylinder and a jig positioning pressing plate fixed to the piston rod end of the downward pressing jig positioning cylinder.

[0009] Furthermore, a tin dipping lifting cylinder is connected to the tin dipping fixing plate.

[0010] Furthermore, the tin furnace component includes a tin furnace body, a tin furnace lifting cylinder, a tin furnace fixing frame, a tin furnace connecting plate, and a tin furnace lifting slide table slidably connected to the tin furnace fixing frame; both ends of the tin furnace lifting cylinder are respectively connected to the tin furnace lifting slide table and the tin furnace fixing frame; the tin furnace body is fixed to the tin furnace lifting slide table through the tin furnace connecting plate; a probe is fixed on the tin furnace fixing frame.

[0011] After adopting the above structure, the beneficial effects of the present utility model are as follows: For a wire core tin dipping structure of the present utility model, after the wire core is clamped and fixed by the wire clamping fixture plate, one end of the wire core to be tinned is arranged on the side far from the inclined push plate; the inclined push cylinder drives the inclined push plate to move forward, pushing the wire clamping fixture plate to rotate on the tin dipping fixing plate against the resistance of the tin dipping fixing spring, and the end of the wire core far from the inclined push plate flips, so that the copper wire section of the wire core can be quantitatively immersed in the tin liquid in the tin furnace assembly; the dipping depth of the copper wire is controlled by the flipping angle of the wire clamping fixture plate pushed by the inclined push cylinder. The tin dipping depth of each wire core is unified, improving the processing quality of the wire, and moreover, replacing manual operation with the push of the inclined push cylinder reduces the labor intensity.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described below with reference to the accompanying drawings.

[0019] As Figures 1 to 4 shown, a wire core tin dipping structure of the present utility model includes a fixture plate pressing assembly F2, a tin furnace assembly F3, and a tin dipping wire clamping fixture F1 for clamping and fixing a wire; the tin dipping wire clamping fixture F1 includes a tin dipping fixing plate F102 and a wire clamping fixture plate F104 rotatably connected to the front end face of the tin dipping fixing plate F102; a tin dipping fixing spring F103 is connected between the tin dipping fixing plate F102 and the wire clamping fixture plate F104;

[0020] The jig plate pushing component F2 includes an inclined pushing cylinder F203 and an inclined pushing plate F204 fixed to the piston rod end of the inclined pushing cylinder F203; the inclined pushing plate F204 is arranged facing the wire clamping jig plate F104;

[0021] The tin dipping fixing spring F103 pulls the wire clamping jig plate F104 to reset the wire clamping jig plate F104; the connection position of the tin dipping fixing spring F103 and the wire clamping jig plate F104 is misaligned with the hinged position of the wire clamping jig plate F104 and the tin dipping fixing plate F102;

[0022] The wire clamping jig plate F104 is provided with a plurality of spring strips for clamping wires, which can clamp multiple core wires at the same time. There is no essential difference from the prior art, so it will not be elaborated here; the wire clamping jig plate F104 is suspended above the tin furnace assembly F3;

[0023] After the wire core is clamped and fixed by the wire clamping jig plate F104, the end of the wire core to be dipped in tin is arranged on the side away from the inclined pushing plate F204; the inclined inclined pushing cylinder F203 drives the inclined pushing plate F204 to move forward, pushing the wire clamping jig plate F104 to rotate on the tin dipping fixing plate F102 against the resistance of the tin dipping fixing spring F103, and the end of the wire core away from the inclined pushing plate F204 flips, so that the copper wire section of the wire core can be quantitatively immersed in the tin liquid in the tin furnace assembly F3; the dipping depth of the copper wire is controlled by the flipping angle of the inclined pushing cylinder F203 pushing the wire clamping jig plate F104. The dipping depth of each wire core is unified, improving the processing quality of the wire, and replacing manual operation by the inclined pushing cylinder F203, reducing the labor intensity.

[0024] As a preferred embodiment of the present invention, the jig plate pushing component F2 further includes a positive pressure positioning module; the positive pressure positioning module includes a downward pressing jig positioning cylinder F201 and a jig positioning pressing plate F202 fixed to the piston rod end of the downward pressing jig positioning cylinder F201;

[0025] The downward pressing jig positioning cylinder F201 and the inclined pushing cylinder F203 are both fixed on an external frame; after the wire clamping jig plate F104 is pushed outwards by the inclined pushing plate F204, the wire clamping jig plate F104 will be placed directly below the jig positioning pressing plate F202, and then the downward pressing jig positioning cylinder F201 is used to push the jig positioning pressing plate F202 to move downwards, so that the wire clamping jig plate F104 can continue to rotate. With the cooperation of the downward pressing jig positioning cylinder F201 and the inclined pushing cylinder F203, the flipping angle of the wire clamping jig plate F104 can reach ninety degrees, which is easy to control the dipping depth of the copper wire in the tin liquid.

[0026] As a preferred embodiment of the present utility model, a soldering lifting cylinder F101 is connected to the soldering fixing plate F102; the soldering lifting cylinder F101 is connected to an external frame, and the soldering fixing plate F102 can be driven by the soldering lifting cylinder F101 to move up and down, so as to adjust the depth between the wire clamping jig plate F104 and the liquid level of the tin bath, and the dipping depth of the copper wire can be adjusted in real time.

[0028] The tin bath fixing frame F304 is fixed to an external frame; the probe F4 has no essential difference from the prior art; the probe F4 extends into the inner cavity of the tin bath body F301. During the soldering process of the wire, the liquid level of the tin bath body F301 will slowly drop. After the probe F4 detects that the tin liquid drops to the set position, the tin bath lifting cylinder F302 is activated to drive the tin bath body F301 to rise a certain distance, so that the horizontal height of the top surface of the tin liquid rises.

[0029] The above is only a preferred embodiment of the present utility model. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the patent application of the present utility model are included in the scope of the patent application of the present utility model.
