Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment for laser cleaning machines, and in particular to a cooling component for a laser cleaning machine. Background Art

[0002] Laser cleaning is a new type of efficient and environmentally friendly cleaning technology that can use the directionality of lasers and high-energy pulsed laser beams to remove pollutants from the surface of materials. After a long period of high-intensity cleaning, the laser cleaning machine gun has heat source components that generate a lot of heat, such as circuit boards.

DETAILED DESCRIPTION

[0031] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1 A cooling assembly for a laser cleaning machine includes: a laser 1, a laser gun body 6 electrically connected to the laser 1 through an electric wire 5, and a mainframe housing 3. The laser 1 is fixedly installed inside the mainframe housing 3, an air conditioner 2 is fixedly installed on the side wall of the mainframe housing 3, and an air inlet 31 is opened through the side wall of the mainframe housing 3 for sending cold air generated by the air conditioner 2 into the mainframe housing 3.

[0033] The power is turned on and the air conditioner 2 is started. The air outlet on the air conditioner 2 inputs cold air into the inside of the main housing 3 through the air inlet 31. It should be noted that the air conditioner 2 is an existing mechanical device for cooling and cooling. It is an existing mature cooling device and will not be described in detail here. The cold air filling the inside of the main housing 3 will cool down the laser 1 during operation.

[0034] See also Figure 1 , Figure 2 as well as Figure 4 A first cooling assembly 4 is provided between the main body shell 3 and the laser gun body 6, for conducting cold air out of the main body shell 3 and cooling the wires 5 between the laser gun body 6 and the main body shell 3, wherein the outer tube 42 and the connecting tube 44 are both hoses, and the outer tube 42 and the connecting tube 44 are both made of plastic material.

[0035] Specifically, the first cooling assembly 4 includes a sleeve 41 that passes through the side wall of the main housing 3, and the port of the sleeve 41 located outside the main housing 3 is connected to an outer tube 42, and the end of the outer tube 42 away from the sleeve 41 is connected to a hollow seat 43, and the hollow seat 43 and the sleeve 41 are both connected to the outer tube 42. The wire 5 passes through the sleeve 41, the outer tube 42 and the hollow seat 43 in sequence, and there is a gap between the outer tube 42 and the wire 5. The first cooling assembly 4 also includes a connecting pipe 44, one end of which is fixedly connected to the hollow seat 43, and the other end of the connecting pipe 44 is connected to the second cooling assembly 7.

[0036] As the amount of cold air inside the main housing 3 continues to increase and the pressure increases, part of the cold air will be discharged into the outer tube 42 through the sleeve 41, and then discharged into the connecting tube 44 through the hollow seat 43 at the end of the outer tube 42. During this process, the cold air inside the main housing 3 and the cold air flowing through the inner side of the outer tube 42 can cool down the entire wire 5, thereby preventing the temperature of the wire 5 from rising due to the long-term working state, causing the wire 5 to age and be damaged, thereby reducing its service life or even causing a fire.

[0037] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 as well as Figure 7 A second cooling assembly 7 is provided outside the laser gun body 6 for receiving cold air delivered from the inside of the first cooling assembly 4 and performing air cooling on the laser gun body 6 .

[0038] Specifically, the second cooling assembly 7 includes an annular winding tube 71 sleeved on the outside of the laser gun body 6, the head end 72 of the annular winding tube 71 is a closed end, and the tail end 73 of the annular winding tube 71 is fixedly connected to the end of the connecting tube 44 away from the hollow seat 43. Air outlet holes 74 are evenly distributed on the inner outer wall of the annular winding tube 71, and the air outlet holes 74 are fixedly connected to the annular winding tube 71. A plurality of limiting components 75 are arranged on the inner outer wall of the annular winding tube 71, and a handle 62 is fixedly connected to the outer wall of the laser gun body 6 for holding the laser gun body 6. A plurality of limiting holes 61 are opened on the outer wall of the laser gun body 6, and the number of the limiting holes 61 and the limiting components 75 are consistent and correspond one to one.

[0039] Furthermore, the limiting component 75 includes an insertion rod 751 fixedly connected to the inner outer wall of the annular winding tube 71, a sleeve 752 is slidably sleeved on the outer side of the insertion rod 751, and a ball seat 753 matching the limiting hole 61 is fixedly connected to the end of the sleeve 752 away from the insertion rod 751. A baffle 755 is fixedly connected to the end of the insertion rod 751 located inside the sleeve 752, a return spring 754 is connected between the baffle 755 and the ball seat 753, and a baffle 756 is fixedly connected to the inner wall of the port of the sleeve 752 away from the ball seat 753.

[0040] Under the action of the connecting tube 44, the cold air flowing through the inner side of the outer tube 42 can be transported to the inside of the annular tube 71 through the tail end 73. As the air pressure inside the annular tube 71 gradually increases, the cooling gas inside the annular tube 71 will be discharged through the air outlet 74 to cool the outer wall of the laser gun body 6, thereby effectively cooling the laser gun body 6 in operation. Under the action of the limiting component 75, it is convenient to install and remove the annular tube 71 on the outer wall of the laser gun body 6.

[0041] Working principle and use process: When in use, turn on the power, the staff holds the laser gun body 6 through the handle 62 to clean the surface of the workpiece to be cleaned. When the laser gun body 6 needs to be used for a long time for cleaning, avoid high temperature damage to the wire 5, the laser 1 and the second cooling component 7 due to long-term high-intensity cleaning work. Start the air conditioner 2, and the air outlet on the air conditioner 2 inputs cold air into the main body shell 3 through the air inlet 31. The cold air filled in the inside of the main body shell 3 will cool the laser 1 during the working process. The cooling is carried out, and as the cold air inside the main housing 3 continues to increase and the pressure becomes larger, part of the cold air will be discharged into the outer tube 42 through the sleeve 41, and then discharged into the connecting tube 44 through the hollow seat 43 at the end of the outer tube 42. In this process, the cold air inside the main housing 3 and the cold air flowing through the inner side of the outer tube 42 can cool down the entire wire 5, avoiding the wire 5 being in a working state for a long time, causing the temperature of the wire 5 to rise, thereby causing aging and damage of the wire 5, reducing its service life, and even causing a fire, posing certain safety hazards.

[0042] In addition, under the action of the connecting tube 44, the cold air flowing through the inner side of the outer tube 42 can be transported to the inside of the annular tube 71 through the tail end 73. As the air pressure inside the annular tube 71 gradually increases, the cooling gas inside the annular tube 71 will be discharged through the air outlet 74 to cool the outer wall of the laser gun body 6, thereby effectively cooling the laser gun body 6 in operation.

[0043] Under the action of the limiting component 75, it is convenient to install and remove the annular winding tube 71 on the outer wall of the laser gun body 6. Specifically, the annular winding tube 71 is pushed on the outside of the laser gun body 6 with force, and a large extrusion force is generated between the ball seat 753 and the limiting hole 61, so that the ball seat 753 and the limiting hole 61 are misaligned, and the ball seat 753 drives the sleeve 752 to slide along the outer wall of the insertion rod 751, and the reset spring 754 is compressed, so that the annular winding tube 71 can be removed from the outside of the laser gun body 6. Similarly, the annular winding tube 71 can also be pushed along the outer wall of the laser gun body 6, so that the ball seat 753 slides against the outer wall of the laser gun body 6 until the ball seat 753 moves to the limiting hole 61. Under the action of the reset spring 754, the ball seat 753 is inserted into the limiting hole 61, and the installation of the annular winding tube 71 on the outside of the laser gun body 6 is completed.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
