Description

Technical Field

[0001] This utility model relates to the field of laser packaging technology, specifically to an automatic welding device for laser tail tubes. Background Technology

[0002] When welding the housing of a fiber laser to the fiber optic tail, resistance welding or electromagnetic induction welding is typically used. Existing resistance welding methods involve manual clamping and manual solder addition, resulting in uncontrollable process parameters and poor product consistency. Current electromagnetic induction technology uses manual or machine-controlled welding, employing pre-formed solder rings, leading to high material costs and long welding times. Utility Model Content

[0003] The purpose of this invention is to provide an automatic welding device for laser tail tubes that achieves precise automatic welding at a lower cost.

[0004] To achieve the above objectives, this utility model provides an automatic welding device for laser tail tubes, comprising: a track, a first sliding module, a second sliding module, a solder transmission module, and a solder rack; the first sliding module and the second sliding module are respectively disposed on the track, and slide along the track; a welding position is provided between the first sliding module and the second sliding module, the welding position being used to place the external tube shell to be welded; the external tube shell to be welded is disposed between the first sliding module and the second sliding module; the first sliding module includes a first slider, a first spring, and a first welding rod; the first slider includes a first receiving groove; the first welding rod includes a first transmission rod and a first electrode; the first transmission rod passes through the first slider and connects to the first electrode; the first spring is disposed in the first receiving groove, and the first spring surrounds the first transmission rod; the extension direction of the first spring is... The two ends of the first sliding block abut against the sidewall of the first receiving groove. After the first slider slides along the track toward the tube shell, the first spring is compressed, and the first electrode is located at the welding position. The second sliding module includes a second slider, a second spring, and a second welding rod. The second slider includes a second receiving groove, and the second welding rod includes a second transmission rod and a second electrode. The second transmission rod passes through the second slider and is connected to the second electrode. The second spring is set in the second receiving groove and surrounds the second transmission rod. The two ends of the second spring in the extension direction abut against the sidewall of the second receiving groove. After the second slider slides along the track toward the tube shell, the second spring is compressed, and the second electrode is located at the welding position. The sidewall of the welding tube is provided with a solder filling port, and the welding tube is provided with a hollow welding groove. The solder rack is used to place the solder wire, and the solder transmission module is used to transmit the solder wire to the solder filling port. The tail end of the external optical fiber to be welded extends into the welding groove.

[0005] As can be seen from the above scheme, this utility model, by setting a first sliding module and a second sliding module, slides the first and second sliding modules toward each other, causing the first and second electrodes to abut against the two sides of the outer shell to be welded. Then, the first slider continues to move toward the shell, compressing the first spring, and the second slider continues to move toward the shell, compressing the second spring, so that the first and second electrodes press firmly against the shell. This allows the compression degree of the first spring to be controlled by adjusting the distance the first slider moves, and the compression degree of the second spring to be controlled by adjusting the distance the second slider moves, thus meeting the welding pressure requirements. Furthermore, the welding transmission module allows for control of the solder entering the solder filling port. This utility model can achieve automatic control and welding of the laser tail tube, accurately control process parameters, and use low-cost solder wire for welding, resulting in lower costs.

[0006] A further design includes a housing connected to a welded pipe; a protection module is also provided on the side of the track, which includes a fixing mechanism and a drive mechanism. The drive mechanism is connected to the fixing mechanism, which includes a pressure plate. The drive mechanism is used to control the fixing mechanism to move above the housing and then press down, and the pressure plate presses the housing.

[0007] Therefore, it can be seen that by setting up a clamping plate, a cover can be fixed to protect the fragile components inside the box and prevent the box from sliding and getting damaged.

[0008] A further solution is to match the shape of the clamping plate to the shape of the box.

[0009] This demonstrates the protective effect of the reinforced clamping plate on the box.

[0010] A further solution is to use a transfer fixture, with the transfer fixture positioned on the opposite side of the track relative to the protection module.

[0011] Therefore, by setting up a transfer fixture, the external optical fiber to be welded can be easily clamped, so that the end of the optical fiber is kept in a good welding position relative to the welding tube of the shell to be welded.

[0012] A further proposed solution is to place the solder transmission module between the second sliding module and the solder frame, with the solder transmission module connected to the second sliding module and sliding along with the second sliding module.

[0013] A further embodiment is that the first sliding module includes a third slider, the first slider being fixedly disposed above the third slider, and the first slider sliding on the track via the third slider; the second sliding module includes a fourth slider, the fourth slider being fixedly disposed above the second slider, and the second slider sliding on the track via the fourth slider.

[0014] A further embodiment is that the solder transmission module includes a transmission mechanism and a first transmission pipe. The inlet of the first transmission pipe is located at the position of the transmission mechanism, and the outlet of the first transmission pipe is located at the solder filling port. The transmission mechanism is used to control the solder wire to enter from the inlet and extend along the length direction of the first transmission pipe.

[0015] A further embodiment is that the solder transmission module includes a housing and a second transmission pipe. The transmission mechanism and the inlet of the first transmission pipe are located inside the housing, and the second transmission pipe is located on the outer wall of the housing and connects the housing with the external environment. Solder wire enters the housing through the second transmission pipe.

[0016] Therefore, it can be seen that by setting up a first and second conveying pipe that match the outer diameter of the solder wire, the conveying of the solder wire is facilitated.

[0017] A further option is to provide a guide block on the second slider, and the guide block is provided with a hollow guide groove that matches the first conveying pipe, through which the first conveying pipe passes.

[0018] This demonstrates that it facilitates accurate positioning of the solder wire.

[0019] A further embodiment is that the first conveying pipe is provided with an opening for exposing the solder wire; the second slider is provided with a fluxing mechanism that faces the opening and provides flux.

[0020] This demonstrates that a good welding environment can be guaranteed. Attached Figure Description

As the second slider 31 continues to move towards the tube shell 11, the second spring 32 is compressed under the action of the sidewall 2111 of the second receiving groove, thereby applying a certain pressure to the tube shell 11 by the second electrode 232. The fourth slider 34 is fixedly disposed above the second slider 31, and the second slider 31 slides on the track 1 via the fourth slider 34.

[0033] The solder transmission module 4 is located between the second sliding module 3 and the solder frame 5. The solder transmission module 4 is connected to the second sliding module 3 and slides with the second sliding module 3.

Specifically, the solder conveying module 4 drives the solder wire 51 to apply the flux provided by the fluxing mechanism 9.

[0039] In this embodiment, the automatic laser tail tube welding device first fixes the outer tube shell 11 to be welded between the first sliding module 2 and the second sliding module 3. The welding tube 102 faces the transfer fixture 7, which clamps the outer optical fiber to be welded. The end of the optical fiber is inserted into the welding groove 1022. Then, the operator sets the welding control parameters (including power, time, and solder length) in the control module 10 and starts the welding.

The transmission mechanism 42 controls the solder wire 51 to enter from the inlet and extend along the length direction of the first conveying pipe 43. The fluxing mechanism 9 applies flux to the solder wire 51 through the opening 431. The first electrode 232 and the second electrode 332 are energized, causing the flux-coated solder wire 51 to melt. Then, the molten solder is injected from the solder filling port 1021, thereby welding the optical fiber tail end and the welding tube 102 together. After welding is completed, the first sliding module 2 and the second sliding module 3 are reset, and the transfer fixture 7 is clamped down, so that the welded tube shell 11 and optical fiber can be removed.
