Description

Technical Field

[0001] This utility model belongs to the field of fin welding production technology, and specifically relates to a cleaning station for a welding robot. Background Technology

[0002] A welding robot cleaning station is an auxiliary device installed in an automated welding system. It is used to automatically clean the welding torch nozzle and contact tip of spatter, residual welding wire, and fumes during or after welding. It also has the functions of automatically cutting welding wire and spraying anti-spatter agent. By keeping the welding torch clean and the arc ignition consistent, it effectively improves welding quality, extends the life of vulnerable parts, reduces downtime maintenance time, and ensures the continuous, stable, and efficient operation of the welding robot.

[0003] Existing welding robots use a cleaning station. After welding, the robot automatically moves to the cleaning station, first using a rotating reamer to clean the slag on the inner wall of the welding torch nozzle, then cutting off excess welding wire, then spraying oil, and finally exiting to complete one automatic cleaning cycle, preparing for the next welding. However, after multiple cleanings, slag adheres to both the inside and outside of the reamer. The slag adhering to the reamer dulls it, making it unable to effectively scrape the slag from the inner wall of the welding torch nozzle. This leads to incomplete cleaning, and the residual slag inside the welding torch nozzle gradually accumulates, ultimately affecting the welding quality. If an external brush is used to clean the reamer, slag will splatter everywhere during the cleaning process, scattering onto the cleaning station body or the workshop floor, causing environmental pollution. Slag accumulation may affect the robot's movement safety and increase the workload of manual cleaning. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a cleaning station for welding robots. Simply pressing the internal threaded cylinder causes the soft brush plate to contact the rotating reamer, achieving rapid cleaning of welding slag inside and outside the reamer. The slag can fall into the collection box for collection, preventing it from scattering in the workshop and keeping the workshop clean.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a cleaning station for a welding robot, including a cleaning box, an installation frame plate slidably arranged inside the cleaning box via a sliding column, a reamer rotatably arranged inside the installation frame plate via a rotating column, a guide cavity frame arranged on the front inner wall of the cleaning box, a soft brush plate slidably arranged inside the guide cavity frame, a connecting column slidably arranged inside the cleaning box, an internal threaded pusher cylinder threadedly connected to the threaded groove on the front side of the connecting column, a spring-loaded reset unit arranged between the internal threaded pusher cylinder and the cleaning box, an adjustable positioning mechanism for positioning the welding torch, an oil spraying mechanism for spraying oil onto the welding torch, and a wire cutting mechanism for cutting welding wire from the welding torch are also provided at the upper end of the cleaning box, the spring-loaded reset unit includes a spring arranged between the internal threaded pusher cylinder and the cleaning box, the spring being sleeved on the outer arc surface of the corresponding connecting column, a collection box slidably arranged inside the cleaning box, and a handle arranged on the front side of the collection box.

[0006] As a further improvement of this utility model, the adjustable positioning mechanism includes a left frame plate disposed on the cleaning gun box. An adjusting positioning plate and a movable positioning plate are slidably mounted inside the left frame plate via a sliding cylinder. A screw is internally threaded into a threaded hole on the rear side of the left frame plate. The screw is rotatably connected to the rear side of the adjusting positioning plate. A knob is provided at the rear end of the screw. An electric push rod is disposed on the front side of the left frame plate. The telescopic end of the electric push rod on the rear side of the left frame plate is connected to the front side of the movable positioning plate. The oil spraying mechanism includes a mechanism disposed on the upper end of the cleaning gun box. The rectangular frame plate has an oil spray pipe inside and an oil outlet hole on the rear side of the rectangular frame plate with an oil drain pipe. The wire cutting mechanism includes a right frame plate at the top of the cleaning gun box. A fixed blade is located on the rear side of the inside of the right frame plate, and a movable blade is located on the front side of the inside of the right frame plate via a slide cylinder. The movable blade and the fixed blade are staggered. A material discharge port corresponding to the positions of the movable blade and the fixed blade is opened at the top of the cleaning gun box. An electric push rod II is located on the front side of the right frame plate, and the telescopic end of the electric push rod II is connected to the front side of the movable blade.

[0007] As a further improvement of this utility model, a support mounting bracket is provided on the lower side of the cleaning box. The cleaning box and the support mounting bracket are fixed together by welding. The support mounting bracket has multiple mounting holes inside, which are located at the four inner corners of the support mounting bracket.

[0008] As a further improvement of this utility model, a motor is installed inside the mounting frame plate, and the output shaft of the motor is connected to the lower end of the rotating column through a coupling. A mounting plate is installed inside the cleaning gun box, and an electric push rod three is installed at the upper end of the mounting plate. The telescopic end of the electric push rod three is connected to the lower side of the mounting frame plate.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, by rotating the knob to drive the screw to rotate, the adjusting positioning plate can be moved precisely under the guidance of the slide cylinder, thereby changing the distance between the adjusting positioning plate and the moving positioning plate, realizing the clamping and positioning of welding guns of different diameters, and improving the versatility and changeover efficiency of the cleaning station.

[0011] Secondly, an external oil pump precisely sprays anti-splatter oil into the welding torch nozzle to form an isolation film, effectively preventing welding slag from adhering. Unattached residual oil automatically flows into the rectangular frame plate and is discharged through the oil drain pipe, avoiding oil spillage and keeping the torch cleaning station clean.

[0012] Third, the lower end of the reamer is equipped with a convex disc-shaped structure that cooperates with the triangular protrusion on the mounting frame plate to form a guide slope, so that the welding slag generated during cleaning can smoothly slide into the collection box under the action of gravity, realizing the automatic centralized collection of welding slag waste.

[0013] Fourth, simply press the internal threaded cylinder to make the soft brush plate contact the rotating reamer, achieving rapid cleaning of the welding slag inside and outside the reamer. The slag can then fall into the collection box for collection, preventing it from scattering in the workshop and keeping the workshop clean. By pressing the internal threaded cylinder, the soft brush plate on the connecting column is brought into contact with the reamer. At this time, the spring is in a compressed state. Then, by controlling the opening of the motor and the electric push rod to move up and down, the reamer rotates and moves up and down, working with the soft brush plate to clean the welding slag attached to the inside and outside of the reamer and let it fall into the collection box.

[0017] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0018] like Figure 1 , 2As shown in Figures 3 and 4, a welding robot cleaning station includes a cleaning box 101. A mounting frame 215 is slidably mounted inside the cleaning box 101 via a sliding column. A reamer 211 is rotatably mounted inside the mounting frame 215 via a rotating column. A guide cavity frame 302 is provided on the front inner wall of the cleaning box 101. A soft brush plate 303 is slidably mounted inside the guide cavity frame 302. A connecting column 305 is slidably mounted inside the cleaning box 101. An internally threaded pusher 301 is threadedly connected to a threaded groove on the front side of the connecting column 305. A springback reset unit is provided between the internally threaded pusher 301 and the cleaning box 101. The springback reset unit includes... The system includes a spring 304 disposed between the internal threaded push cylinder 301 and the cleaning gun box 101. The spring 304 is sleeved on the outer arc surface of the corresponding connecting column 305. The upper end of the cleaning gun box 101 is also provided with an adjustable positioning mechanism for positioning the welding gun, an oil spraying mechanism for spraying oil onto the welding gun, and a wire cutting mechanism for cutting the welding wire. The mounting frame plate 215 is equipped with a motor 218. The output shaft of the motor 218 is connected to the lower end of the rotating column through a coupling. The cleaning gun box 101 is equipped with a mounting plate 217. The upper end of the mounting plate 217 is equipped with an electric push rod 216. The telescopic end of the electric push rod 216 is connected to the lower side of the mounting frame plate 215.

[0019] like Figure 1 , 2 As shown in Figures 3 and 4, the adjustable positioning mechanism includes a left frame plate 210 mounted on the cleaning gun box 101. Inside the left frame plate 210, an adjusting positioning plate 203 and a movable positioning plate 204 are slidably mounted via a slide cylinder. A screw 214 is internally threaded into an internally threaded hole on the rear side of the left frame plate 210. The screw 214 is rotatably connected to the rear side of the adjusting positioning plate 203. A knob 209 is mounted at the rear end of the screw 214. An electric push rod 205 is mounted on the front side of the left frame plate 210. The telescopic end of the electric push rod 205 on the rear side of the left frame plate 210 is connected to the front side of the movable positioning plate 204.

[0020] When the welding robot's welding torch needs cleaning, the welding torch is moved between the adjusting positioning plate 203 and the moving positioning plate 204. Then, by controlling the operation of the electric push rod 205, the telescopic end, constrained by the slide tube, drives the moving positioning plate 204 backward, cooperating with the adjusting positioning plate 203 to clamp and fix the welding torch, ensuring that the nozzle of the welding torch is coaxial with the reamer 211. Next, by controlling the operation of the motor 218, the output shaft drives the reamer 211 on the rotating column to rotate. Immediately afterwards, by controlling the operation of the electric push rod 216, the telescopic end drives the reamer 211 inside the mounting frame plate 215 to move upward, passing through the torch cleaning box 1. The welding torch nozzle is inserted into the round hole 01, and the welding slag on the inner wall of the nozzle is scraped off by the rotating reamer 211. Then, the electric push rod 205 is controlled to move the positioning plate 204 away from the adjusting positioning plate 203 to release the clamping of the welding torch, thereby cleaning the welding slag inside the nozzle, restoring the original inner diameter of the nozzle, and ensuring the smooth flow of the shielding gas. The screw 214 is rotated by rotating the knob 209, which can drive the adjusting positioning plate 203 to move under the restriction of the slide. The size of the clamped and fixed welding torch can be changed by coordinating the movement position of the positioning plate 204, and the reamer 211 and the welding torch nozzle can be ensured to be coaxial.

[0021] like Figure 1 , 3 As shown, the oil injection mechanism includes a rectangular frame plate 202 disposed on the upper end of the cleaning gun box 101, an oil injection pipe 212 disposed inside the rectangular frame plate 202, and an oil drain pipe 213 disposed in the oil outlet hole opened on the rear side of the rectangular frame plate 202.

[0022] First, the oil spray pipe 212 is connected to an external oil supply pump box. Then, the welding robot moves the welding torch to the upper end of the oil spray pipe 212 and controls the external oil supply pump to spray anti-splatter oil into the inside of the welding torch nozzle. An isolation film is formed on the inner wall of the nozzle, making it difficult for spatter generated during welding to adhere and keeping the nozzle unobstructed. The anti-splatter oil that does not adhere to the nozzle falls into the inside of the rectangular frame plate 202 and can be discharged from the inside of the rectangular frame plate 202 through the oil drain pipe 213.

[0023] like Figure 1 , 3 As shown, the wire cutting mechanism includes a right frame plate 201 located at the upper end of the cleaning gun box 101. A fixed blade 206 is located on the rear side of the inside of the right frame plate 201, and a movable blade 207 is located on the front side of the inside of the right frame plate 201 via a sliding cylinder. The movable blade 207 and the fixed blade 206 are staggered. A material discharge port corresponding to the positions of the movable blade 207 and the fixed blade 206 is opened at the upper end of the cleaning gun box 101. An electric push rod 208 is located on the front side of the right frame plate 201, and the telescopic end of the electric push rod 208 is connected to the front side of the movable blade 207.

[0024] The welding robot moves the welding wire in the welding torch between the moving blade 207 and the fixed blade 206. Then, by controlling the operation of the electric push rod 208, the telescopic end drives the moving blade 207 to move backward under the constraint of the slide tube, which works with the fixed blade 206 to cut the welding wire. This ensures that the welding wire extension length (usually 8-15mm) is consistent and appropriate at the beginning of each welding operation, thereby ensuring the success rate of arc ignition and the stability of welding quality. Because the moving blade 207 and the fixed blade 206 are staggered, they can avoid damage caused by hard contact after cutting the welding wire.

[0025] like Figure 1 , 3 As shown in Figure 4, a collection box 103 is slidably disposed inside the cleaning box 101. The frictional resistance between the collection box 103 and the cleaning box 101 prevents the welding torch from sliding out of the collection box 103 during cleaning. A handle is provided on the front side of the collection box 103.

[0026] When the reamer 211 rotates to clean the inside of the welding torch nozzle, the welding slag can smoothly slide into the collection box 103 because the lower end of the reamer 211 is convex and the upper end of the mounting frame plate 215 is triangular protrusion. The cut welding wire can also fall into the collection box 103 through the material drop port.

[0027] When the reamer 211 needs cleaning, pressing the internal threaded cylinder 301 causes the soft brush plate 303 on the connecting column 305 to contact the reamer 211. At this time, the spring 304 is in a compressed state. Then, by controlling the motor 218 and the electric push rod to move up and down, the reamer 211 rotates and moves up and down, working with the soft brush plate 303 to clean the welding slag attached to the inside and outside of the reamer 211 and drop it into the collection box 103. After cleaning, the personnel release the internal threaded cylinder 301 and the spring 304 quickly rebounds to its original position, causing the soft brush plate 303 to move away from the reamer 211, quickly ending the cleaning of the reamer 211. The collection box 103 can be slid out from the gun cleaning box 101 by the handle to process the welding slag collected inside. When the spring 304 is fatigued, the internal threaded cylinder 301 can be unscrewed from the rotating column by rotating counterclockwise, and the spring 304 can be removed from the outer arc surface of the connecting column 305 for replacement.

[0028] According to another embodiment of the present invention, such as Figure 1 As shown, a support mounting bracket 102 is provided on the lower side of the cleaning gun box 101. The support mounting bracket 102 has multiple mounting holes inside. The cleaning gun station can be installed next to the welding robot through the support mounting bracket 102 and its internal mounting holes, making the cleaning of the welding gun more stable.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
