Description

Technical Field

[0001] The utility model belongs to the technical field of laser welding, and in particular relates to a laser physical water cooling device. Background Art

[0002] When welding cylindrical products, the welding gun needs to be inserted into the cylinder. Due to the high temperature during welding, the heat is always condensed in the cylinder and cannot be ventilated, so the laser device on the welding gun is always in a high temperature state. Since the laser is an electronic device, the working environment is always in a high temperature state, which will affect or even damage the function of the laser device.

[0003] Therefore, a device that can be fixed together with the laser and can effectively cool the laser is needed. Utility Model Content

[0004] The utility model aims to provide a laser physics water-cooling device, characterized in that it comprises a water-cooling front plate, a water-cooling back plate and a connecting plate, wherein the water-cooling front plate is fixed to the front of the laser device, the water-cooling back plate is fixed to the back of the laser device, and the connecting plate is fixed to one side of the laser device, and the water-cooling front plate and the water-cooling back plate are connected to each other via the connecting plate;

[0005] The sides of the water-cooled front panel and the water-cooled back panel facing the laser device are both concave with flow grooves, and water-cooling pipes are laid in the flow grooves. The water-cooling pipes are provided with water inlets and water outlets, and the water inlets and water outlets are both equipped with quick-connect plugs. The water-cooling pipes are connected to the cooling device that stores coolant through the quick-connect plugs and pipes, forming a loop between the cooling device and the water-cooling pipes.

[0006] Furthermore, a heat-conducting insulating silicone sheet is provided between the laser device and the water-cooled front panel, the water-cooled back panel and the connecting plate.

[0007] Furthermore, a window is provided on the water-cooled front panel at the laser display light, and a water-cooling pipeline located inside the water-cooled front panel is arranged to avoid the window.

[0008] Furthermore, the water-cooled front panel and the water-cooled back panel are integrally extended with a connecting block on the side facing the quick-connect plug. Both connecting blocks are provided with threaded holes, one of which is provided with a countersunk hole. The water-cooled front panel and the water-cooled back panel are also connected and fixed to each other by screws and threaded holes.

[0009] Furthermore, the height of the connecting plate is lower than the height of the laser lens in the laser device.

[0010] Compared with the prior art, the beneficial effects of the present invention are mainly reflected in:

[0011] 1. The utility model achieves the purpose of cooling the laser device through the physical cooling method of water cooling. The cooling water comes out of the cooling device, passes through the water cooling pipeline and returns to the cooling device to form a loop. It has been verified that this device can greatly reduce the working environment temperature of the laser and has obvious effects.

[0012] 2. The water-cooled front panel, water-cooled back panel and connecting plate of the present invention are all made of aluminum, which reduces the weight of the objects fixed on the laser device.

[0013] 3. The utility model perfectly solves the problem that the traditional water-cooling pagoda head is prone to water leakage and does not match the water pipe size by providing a quick-connect plug. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a more detailed description of a laser physical water cooling device of the present invention in conjunction with a schematic diagram, which shows a preferred embodiment of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as being widely known to those skilled in the art and not as a limitation to the present invention.

[0021] like Figure 1 and 2As shown, a laser physics water-cooling device for a laser device 2 includes a cooling device, a water-cooled front panel 3, a water-cooled back panel 4, and a connecting plate 5. The cooling device stores coolant and is equipped with a pump to circulate the coolant. The water-cooled front panel 3 is bolted to the front of the laser device 2, and the water-cooled back panel 4 is fixed to the back of the laser device 2. The two panels are arranged opposite each other and are also connected to each other by a connecting plate 5. The connecting plate 5 is bolted to the front side of the laser device 2, and its two sides are bolted to the same side of the water-cooled front panel 3 and the water-cooled back panel 4 respectively. A fixing block 10 integrally extends from the side of the water-cooled front panel 3 and the water-cooled back panel 4 facing away from the connecting plate 5. The fixing block 10 is provided with threaded holes, each of which is countersunk. The water-cooled front panel 3 and the water-cooled back panel 4 are also connected and fixed to each other by screws.

[0022] It should be noted that the height of the connecting plate 5 needs to be lower than the height of the laser lens 9 in the laser device 2 and cannot block the shift port of the laser lens 9. The utility model sets the connecting plate 5 to be 5 mm lower than the lens replacement port.

[0023] refer to Figure 4 and Figure 5 To cool the laser device 2, we have recessed flow channels on the opposite sides of the cooling front panel and cooling back panel fixed to the front and back of the laser device 2. The flow channels are arranged in a zigzag pattern on the sides of the two panels to maximize coverage and thus achieve the maximum cooling effect. A water-cooling pipe 7 is laid in the flow channel. Water-cooling pipe 7 has a water inlet and outlet at both ends, located on the same side of the cooling front panel and cooling back panel. The inlet and outlet are threaded with stainless steel quick-connect plugs 6. The quick-connect plugs 6 are connected to a pipeline and are connected to the cooling device through the pipeline. The water-cooling pipe 7 is connected to the cooling device filled with coolant through the quick-connect plugs 6, forming a loop. The coolant circulates in the water-cooling pipe 7, circulating and removing heat from the laser device 2, thereby cooling the laser device 2.

[0024] The utility model is provided with a quick-connect plug 6 because the traditional pagoda is prone to water leakage and is not compatible with the size of the water pipe. The quick-connect plug 6 can perfectly solve this problem.

[0025] We also wrapped a layer of thermally conductive insulating silicone sheet around the side of the laser device 2, which can not only conduct the heat of the laser to the water cooling but also provide insulation.

[0026] A window 8 for the laser display light is provided on the outer periphery of the laser device 2 . When setting the flow channel groove, the flow channel groove in the water-cooled front panel 3 is used to avoid the window 8 .

[0027] refer to Figure 3The laser device 2 of the present invention is fixed to the rotary bearing at the end of the robot arm 1 through a connecting piece and bolts, and the welding work of the laser device 2 is realized through the robot arm 1.

[0028] A laser line connector is provided at the bottom of the laser device, and the laser device 2 is connected to a power source via the laser line connector to operate.

[0029] The above description is merely a preferred embodiment of the present invention and does not limit the present invention in any way. Any person skilled in the art who, without departing from the scope of the present invention, makes any equivalent substitution, modification, or other variation to the technical solution and technical content disclosed herein shall be deemed to fall within the scope of the present invention and remain within the scope of protection of the present invention.
