During the welding process, it is necessary to observe the situation of the welding point. Currently, a coaxial camera is basically used to observe the welding process in real time. Since the laser energy is relatively large during the welding process, the flame will affect the imaging effect of the camera. Therefore, a blue light lamp is required to irradiate the welding point. During the welding process, there are lenses on the optical path that can filter out the light in the laser working band and allow the light in the blue light band to pass through, thereby realizing the video image of the welding process. Due to the high power of the blue light lamp, the narrow space causes slow heat dissipation, and there is also the influence of the reflected heat during the welding process. The temperature of the actual working environment of the blue light lamp exceeds the temperature range specified for its effective operation, resulting in the situation that the blue light lamp is easily burned out.

[0032] Combined with Figures 1 to 5 As shown, the present utility model provides a blue light body for laser welding, including:

[0033] A lamp holder 1, the lamp holder 1 having a lamp installation part 11;

[0034] Bottom cover 2, the bottom cover 2 is covered on the lamp holder 1 and encloses a cooling cavity 3 with the lamp holder 1, and the cooling cavity 3 is located on the back of the lamp installation part 11; there is coolant in the cooling cavity 3;

[0035] Blue light lamp body 4, the blue light lamp body 4 is located in the lamp installation part 11.

[0036] Compared with the prior art, for the problem that the blue light lamp body 4 is prone to burnout because the temperature of the actual working environment exceeds the temperature range specified for its own effective operation, a cooling cavity 3 filled with coolant is provided on the back of the blue light lamp body 4. The coolant is used to absorb the heat of the blue light lamp body 4 and its vicinity, accelerate the heat dissipation speed of the blue light lamp body 4, achieve the effect of cooling the blue light lamp body 4, thereby avoiding the situation of burnout of the blue light lamp body 4 and effectively extending the service life of the blue light lamp body.

[0037] Furthermore, to avoid water leakage, an elastic sealing ring is provided between the bottom cover 2 and the lamp holder 1.

[0038] Furthermore, the cooling cavity 3 has a liquid inlet 31 and a liquid outlet 32; the liquid inlet 31 and the liquid outlet 32 are connected by a pipeline to a cooling circulation device located outside the lamp holder 1; in this way, the coolant can circulate in the cooling cavity 3. After the coolant exchanges heat in the cooling cavity 3, it flows through the pipeline to the cooling circulation device to be cooled, and then flows back into the cooling cavity 3 to exchange heat again. This cycle repeats, keeping the coolant that re-enters the cooling cavity 3 at a certain low temperature, effectively improving the heat exchange efficiency and saving the amount of coolant used.

[0039] It should be noted that the coolant is cooling water, and the cooling circulation device is a cooling water circulation device, which belongs to the existing conventional technology and its composition will not be elaborated here.

[0040] Furthermore, the cooling cavity 3 is composed of a channel, the liquid inlet 31 and the liquid outlet 32 are respectively communicated with the channel, and the channel extends along the position of the blue light lamp body 4. After the coolant enters the channel through the liquid inlet 31, it flows along the channel, takes away the heat of the blue light lamp body 4, and finally is discharged to the cooling circulation device through the liquid outlet 32. Preferably, a groove 12 is provided on the side of the lamp holder 1 facing the bottom cover 2, and the groove 12 constitutes the channel.

[0041] Furthermore, in combination with Figure 2 、 Figure 4 and Figure 5As shown, the blue light lamp body 4 has a plurality of lamp beads 41. The plurality of lamp beads 41 are arranged in a circle around the same axis 5, and the focus point of each lamp bead 41 is located on the axis 5. The inclination angles of the plurality of lamp beads 41 with respect to the axis 5 are different. Due to the different inclinations of the lamp beads 41, the heights of the corresponding focus points of the lamp beads 41 are different, which is suitable for illuminating the workpiece to be welded at different welding heights within a certain range.

[0042] Further, a positioning groove 21 is provided on the back surface of the bottom cover 2. The positioning groove is used for mating connection with an external laser welding head to play a positioning role, so that the axis 5 common to the plurality of lamp beads 41 is concentric with the output end of the laser welding head.

[0043] Further, the blue light lamp body 4 further has a PCB board. The plurality of lamp beads 41 are arranged on the PCB board; the PCB board is detachably connected to the lamp installation part 11 and can be flexibly replaced. The PCB board and the lamp installation part 11 can be detachably connected by means of screw fixation, adhesive connection, or clamping connection.

[0044] Further, the blue light lamp for laser welding further includes a light-transmitting plate 6. The light-transmitting plate 6 covers the lamp installation part 11 to protect the blue light lamp body 4 located at the lamp installation part 11 and effectively prevent the blue light lamp body 4 from being damaged due to external impact or other external factors.

[0045] Further, in combination with Figure 2 As shown, to provide sufficient space for heat dissipation of the blue light lamp body 4, there is a spacing between the surface of the light-transmitting plate 6 facing the blue light lamp body 4 and the blue light lamp body 4.

[0046] Further, the light-transmitting plate 6 is a light-transmitting glass, and it is not easy to be worn by the sparks splashed during welding.
