Description

Technical Field

[0001] The invention belongs to the technical field of cable tinning, and in particular relates to a coaxial cable tinning method and a tinning mechanism. Background Art

[0002] Cables are a type of raw material that is widely used in the electronics industry. For example, coaxial cables require a riveted terminal at one end and a tinned terminal at the other end. Therefore, when welding, the tin at the end of the cable is melted to achieve welding.

[0003] When the current coaxial cable is soldered on the circuit board, it is necessary to solder the conductor of the core and the braided shielding layer on the circuit board; therefore, it is necessary to strip the braided layer and conductor of the cable; and both the conductor and the braided layer must be tinned. At present, after the braided layer and conductor of the cable are stripped by a cutting and stripping machine, they are dipped in flux and tinned together, so that the liquid tin is stained on the braided layer and the conductor. Since the liquid tin is fluid and the specific gravity of tin is large, after the braided layer is tinned, the tinned end will sag, causing the tin to flow to the front end, causing the tin at the front end of the braided layer to accumulate into a lump, and the braided layer is in a mesh shape, so the amount of adsorption is too large; therefore, when the braided layer is soldered on the circuit board, due to excessive tin, the braided layer will have a large area of ​​tin after soldering, which will cause the tin of the soldered braided shielding layer to be connected to other electronic components, causing a circuit short circuit. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0044] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the coaxial cable tinning method includes the following steps:

[0045] S10, the cable is fixed in length, and a cut is made at the end of the cable for stripping the insulation. Specifically, the cable is cut to the required length, and a cut is made at the end of the cable, the depth of the cut just reaches the outer circle of the braided shielding layer to avoid cutting the braided shielding layer.

[0046] S20, stripping the insulation skin of the outer layer of the cable from the incision to expose the braided shielding layer. Specifically, this step is to use a stripping mechanism to strip the insulation skin of the outer layer of the cable from the incision of the cable to expose the braided shielding layer.

[0047] S30, the braided shielding layer is stained with solder flux, and one end of the braided shielding layer of the cable extends into the solder flux. In this step, after the outer insulation layer of the cable end is stripped, the exposed braided shielding layer is completely immersed in the solder flux, so that the braided shielding layer is stained with solder flux.

[0048] S40, tinning the braided shielding layer, the end of the cable stained with solder flux is extended into the tin box, and the liquid tin adheres to the braided shielding layer. In this step, after the braided shielding layer is stained with solder flux, the braided shielding layer is immersed in molten tin, so that the molten tin is adsorbed on the braided shielding layer, and according to the principle of fluid mechanics, the molten tin will flow along the end of the braided shielding layer and accumulate at the end, while the tin in other parts will be evenly distributed.

[0049] S50, cutting and stripping the insulating layers of the braided shielding layer and the core wire, at the end of the cable, cutting the braided shielding layer stained with tin, and cutting to the conductor of the core wire, stripping the cut braided shielding layer and the insulating layer of the core wire along the cut to expose the conductor of the core wire; in this step, the braided shielding layer and the insulating layer of the core wire are cut by the cutting and stripping mechanism according to the requirement of the conductor length, and both are stripped to expose the conductor. After the braided shielding layer is stripped, the tin on the remaining braided shielding layer is evenly distributed and meets the requirements of soldering.

[0050] S60, the conductor is dipped in soldering flux, and the exposed conductor of the cable after stripping is inserted into the soldering flux so that the soldering flux is adsorbed on the surface of the conductor.

[0051] S70, conductor tinning, the conductor that occupies tin is extended into the liquid tin, the tin adheres to the surface of the conductor, and the coaxial cable is completely tinned.

[0052] In this embodiment, the outer insulating layer of the cable end is first stripped to expose the braided shielding layer, and the braided shielding layer is dipped with flux and then tinned. According to fluid mechanics, the tin at the end of the braided layer will accumulate more and form clumps, while the tin at the braided shielding layer away from the end is distributed more evenly. Then the front end of the braided shielding layer and the insulation skin of the wire core are stripped to expose the conductor of the wire core, and then the conductor is dipped with flux and tinned. Since the front end of the braided shielding layer is cut off after the braided shielding layer is dipped with tin, the tin on the braided shielding layer is uniform and avoids excessive accumulation. Therefore, when the braided shielding layer is soldered on the circuit board, it can effectively prevent excessive solder from connecting to other electronic components.

[0053] Furthermore, S45 is provided between S30 and S40 to dry the solder flux attached to the braided shielding layer. In this embodiment, a drying step is added after the solder flux is applied and before the solder tinning step; because the shielding layer is braided and has many gaps in the middle, more solder flux will be attached. In order to speed up the drying of the solder flux, a drying step is added to speed up the drying efficiency of the solder flux, thereby improving the solder tinning efficiency.

[0054] Further, in S50, when the braided shielding layer and the insulation layer of the wire core are stripped, the stripping mechanism drives the braided shielding layer and the insulation layer of the wire core to twist, so that the wire core is twisted. In this embodiment,

In this embodiment, the outer insulating layer of the cable end is stripped by the first cutting and stripping mechanism 300, so that the internal braided shielding layer is exposed, and the tinned end of the cable is clamped by the wire clamping mechanism 200. The circulating conveying mechanism 100 conveys the cable through the first fluxing mechanism 400 to complete the fluxing of the braided shielding layer, the first tinning mechanism 500 to complete the tinning of the braided shielding layer, the second cutting and stripping mechanism 600 to complete the cutting and stripping of the front end of the braided shielding layer and the insulation of the wire core after tinning, the second fluxing mechanism 700 to complete the fluxing of the conductor part of the wire core, and the second tinning mechanism 800 to complete the tinning of the conductor. After the braided shielding layer is tinned, the second cutting and stripping mechanism 600 cuts off the front end of the braided shielding layer and the insulation layer of the wire core and strips it. Therefore, the tin on the braided shielding layer is evenly distributed and excessive accumulation is avoided. Therefore, when the braided shielding layer is soldered on the circuit board, it can effectively prevent excessive solder from connecting to other electronic components. In this embodiment:

In this embodiment, the cable cut and stripped by the first cutting and stripping mechanism 300 is clamped by the clamping mechanism 200; the driving mechanism drives the turntable 102 to rotate, thereby driving the cable to stepwisely operate, so as to sequentially complete the tinning of the braided shielding layer and the tinning of the conductor.
