Description

Technical Field

[0001] This invention relates to a robot, and more specifically, to an intelligent control system for a laser welding robot. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. It boasts advantages such as high efficiency, precision, and ease of use. However, in long-distance welding processes, the spatter generated by laser welding severely affects the surface quality of the weld. This typically manifests as numerous metal particles adhering to the surface of the material or workpiece after laser welding. The cause of this phenomenon is usually that the surface of the processed material or workpiece was not properly cleaned, leaving oil stains or debris. These metal particles and debris from the previous welding operation then affect the quality of subsequent welds, creating a vicious cycle. Therefore, an intelligent control system for laser welding robots that can promptly clean the weld area before welding is needed.

[0003] For the reasons mentioned above, how to clean the weld area in a timely manner before welding is the problem that this application addresses. Summary of the Invention

[0004] To address the shortcomings of existing technologies, an intelligent control system for laser welding robots is provided, which can clean the welding area in a timely manner before welding.

[0005] To achieve the above objectives, the following technical solution is provided: an intelligent control system for a laser welding robot, comprising a housing, a remote control motor and a welding head installed inside the housing, the remote control motor connected to a drive assembly, the drive assembly connected to a cleaning assembly, the cleaning assembly including a reservoir for storing cleaning fluid, the reservoir having a first through hole facing the bottom of the housing for discharging the cleaning fluid, the bottom of the housing also having a scraper disposed behind the first through hole and a ventilation hole disposed behind the scraper fixedly connected, and an exhaust assembly connected to the side of the housing away from the reservoir, the exhaust assembly including multiple fans and a collection chamber disposed below the fans and detachably connected to the housing.

[0006] In summary, the above technical solution has the following beneficial effects: For oil stains, common cleaning solutions are used to dissolve them. Therefore, a liquid storage tank is set up to store the cleaning solution. When in use, the cleaning solution can drip onto the surface of the workpiece through the first through hole to dissolve the oil stains on the workpiece surface. Since the density of oil stains is usually less than that of the cleaning solution, they will concentrate at the top of the cleaning solution after being dissolved. Then, when the drive component moves the housing, the scraper scrapes the cleaning solution after dissolving the oil stains out of the welding work area. Since the scraper scrapes from the bottom of the cleaning solution, it can effectively remove the oil stains from the welding work area, leaving only a small amount of residual cleaning solution. At this time, since the fan continues to rotate, a structure similar to a vacuum cleaner is formed through the ventilation holes. This can accelerate the air circulation speed at the bottom of the housing and quickly evaporate the small amount of residual cleaning solution, thereby achieving the effect of cleaning the oil stains on the surface of the workpiece.

[0007] For debris, an exhaust assembly is used for ventilation. Since the scraper is located between the first through hole and the ventilation hole, the airflow is blocked by the scraper when the exhaust assembly is used, which will prevent the cleaning liquid flowing out of the first through hole from spreading. Secondly, because the debris is light, it can be carried by the flowing air and enter the housing from the ventilation hole. It will hit the fan or the inner wall of the housing on the side where the fan is located along the airflow direction and then be transferred into the collection chamber, thereby achieving the effect of cleaning debris from the surface of the workpiece.

[0008] This invention uses a trolley to control the position of the welding head, and while moving, it uses cleaning fluid to remove oil stains. The scraper can scrape off the cleaning fluid as the housing moves, and the exhaust component can simultaneously evaporate the residual cleaning fluid and suck up debris, thereby achieving the purpose of cleaning the welding area in time before welding.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] Reference Figure 1-4 As shown, an intelligent control system for a laser welding robot includes a housing 1, a remote control motor 2 and a welding head 3 installed inside the housing 1, the remote control motor 2 connected to a drive assembly 4, the drive assembly 4 connected to a cleaning assembly 5, the cleaning assembly 5 including a storage tank 51 for storing cleaning fluid, the storage tank 51 having a first through hole 52 facing the bottom of the housing 1 for discharging the cleaning fluid, the bottom of the housing 1 also having a scraper 53 disposed behind the first through hole 52 and a ventilation hole 61 disposed behind the scraper 53 fixedly connected, the side of the housing 1 away from the storage tank 51 is also connected to an exhaust assembly 6, the exhaust assembly 6 including multiple fans 62 and a collection tank 63 disposed below the fans 62 and detachably connected to the housing 1;

[0025] For oil stains, common cleaning solutions are used to dissolve them. Therefore, a storage tank 51 is provided to store the cleaning solution. When in use, the cleaning solution can drip onto the surface of the workpiece through the first through hole 52 to dissolve the oil stains on the workpiece surface. Since the density of oil stains is usually less than that of the cleaning solution, they will concentrate on the top of the cleaning solution after being dissolved. Then, when the drive component 4 moves the housing 1, the scraper 53 scrapes the cleaning solution after dissolving the oil stains out of the welding work area. Since the scraper 53 scrapes from the bottom of the cleaning solution, it can effectively remove the oil stains from the welding work area, leaving only a small amount of residual cleaning solution. At this time, since the fan 62 continues to rotate, it forms a structure similar to a vacuum cleaner through the ventilation hole 61. This can accelerate the air circulation speed at the bottom of the housing 1 and quickly evaporate the small amount of residual cleaning solution, thereby achieving the effect of cleaning the oil stains on the surface of the workpiece.

[0026] For debris, the exhaust assembly 6 is used for ventilation. Since the scraper 53 is located between the first through hole 52 and the ventilation hole 61, the airflow is blocked by the scraper 53 when the exhaust assembly 6 is used for ventilation, so that the cleaning liquid flowing out of the first through hole 52 will not be scattered. Secondly, because the debris is light, it can be carried by the flowing air and enter the interior of the housing 1 through the ventilation hole. It impacts the fan 62 or the inner wall of the housing 1 on the side where the fan 62 is located along the airflow direction and is then transferred into the collection chamber 63, thereby achieving the effect of cleaning the debris on the surface of the workpiece.

[0027] The present invention uses a trolley to control the position movement of the welding head 3, and uses cleaning fluid to clean oil stains while moving. The scraper 53 can scrape off the cleaning fluid as the housing 1 moves, and the exhaust component 6 can simultaneously evaporate the residual cleaning fluid and suck up debris, thereby achieving the purpose of cleaning the welding area in time before welding.

[0028] Furthermore, the drive assembly 4 includes a first drive shaft 41 connected to the remote control motor 2. The two ends of the first drive shaft 41 extend out to the outside of the housing 1 and are symmetrically and fixedly connected to the first tires 42 that are rotatably connected to the housing 1. The drive assembly 4 also includes a second drive shaft 43 passing through the housing 1. The two ends of the second drive shaft 43 extend out to the outside of the housing 1 and are symmetrically and fixedly connected to the second tires 44 that are rotatably connected to the housing 1.

[0029] The first drive shaft 41 is also fixedly connected to two first drive wheels 411 located on both sides inside the housing 1. The second drive shaft 43 is also fixedly connected to two second drive wheels 431 located on both sides inside the housing 1. The first drive wheels 411 are meshed with a drive belt 45 that meshes with the corresponding second drive wheel 431. The drive belt 45 is connected to a tensioner 46 fixedly connected to the housing 1. The second drive shaft 43 is also fixedly connected to a stabilizer 432 fixedly connected to the housing 1 and used to stabilize the second drive shaft 43.

[0030] The tensioner 46 includes a third drive wheel 461 that meshes with the drive belt 45. The third drive wheel 461 is rotatably connected to a sliding member 462 that is slidably connected to the side wall of the housing 1. The sliding member 462 is fixedly connected to a first spring 463 that is fixedly connected to the bottom of the housing 1. The housing 1 is also fixedly connected to a guide rail 464 for guiding the sliding member 462 to move up and down.

[0031] The first drive shaft 41 is also rotatably connected to two first support members 412 that are fixedly connected to both sides of the housing 1 respectively; the second drive shaft 43 is also rotatably connected to two second support members 433 that are slidably connected to both sides of the housing 1 respectively.

[0032] Both the first support member 412 and the second support member 433 are provided with protective shells 47 on their outer sides;

[0033] When the remote control motor 2 is started, it can drive the first drive shaft 41 and the first tire 42 to rotate in sequence, thereby enabling the robot to move forward. In addition to moving forward passively, the second tire 44 can also be driven to rotate in sequence through the transmission belt 45 and the second drive shaft 43 when the first drive shaft 41 rotates, thereby enhancing the robot's mobility.

[0034] Since the robot needs to move a long distance on the workpiece surface, the workpiece surface may have uneven surfaces that cause the robot to vibrate. In order to prevent the second tire 44 from making slight deviations, a stabilizer 432 is provided. In addition, in order to prevent the transmission belt 45 from becoming taut and breaking when the second drive shaft 43 moves slightly due to vibration, a tensioner 46 is provided for cushioning.

[0035] The third drive wheel 461 in the tensioner 46 is always engaged with the drive belt 45. When the robot is moving in a straight line normally, the third drive wheel 461 slightly presses down the drive belt 45, making the drive belt 45 form a triangular shape. When the robot vibrates, the drive belt 45 on one side is stretched by the second drive wheel 431, and the third drive wheel 461 on that side moves to a certain extent, which changes the distance between the upper and lower parts of the drive belt 45, thereby increasing or decreasing the length of the drive belt 45 in the direction of movement, while the other side does the opposite. When the robot moves to a stable surface, the third drive wheel 461 is reset by the action of the first moving part and the first spring 463.

[0036] The first support member 412 can prevent the first drive shaft 41 from falling and colliding with the housing 1, and the second support member 433 can prevent the second drive shaft 43 from falling and colliding with the housing 1.

[0037] The protective shell 47 can prevent debris from being blown into the gap between the first drive shaft 41 and the housing 1 and the gap between the second drive shaft 43 and the housing 1 when the exhaust assembly 6 is started, thus avoiding jamming and inability to move.

[0038] Furthermore, the top of the liquid storage tank 51 is provided with an inlet 511, the first through hole 52 is fixedly connected to a first one-way ventilation device 521, the liquid storage tank 51 is provided with a concave receiving space 512, the receiving space 512 is provided with a first airbag 513 communicating with the liquid storage tank 51, the first airbag 513 is provided with a second one-way ventilation device 514 at the connection between the first airbag 513 and the liquid storage tank 51, the first airbag 513 is provided with a second through hole 515 on the side away from the liquid storage tank 51, and a contact member 541 is abutted against, the contact member 541 is fixedly connected to a moving rod 54 on the side away from the first airbag 513, the moving rod 54 is slidably connected to a third support member 542 fixedly connected to the shell 1, the contact member 541 is also fixedly connected to a second spring 543 connected to the third support member 542, and a plurality of arc-shaped members 544 for abutting the moving rod 54 are also fixedly connected to the first drive shaft 41;

[0039] When the arc-shaped component 544 abuts against the moving rod 54, the contact point of the arc-shaped component 544 against the moving rod 54 gradually moves away from the rotation center of the first transmission shaft 41.

[0040] The first one-way ventilation device 521 includes a first elastic gasket 522 for sealing the first through hole 52, and a first connector 523 fixedly connected to the housing 1 at both ends of the first elastic gasket 522. The second one-way ventilation device 514 includes a second elastic gasket 516 for sealing the connection between the first airbag 513 and the liquid storage tank 51, and a second connector 517 fixedly connected to the inner wall of the liquid storage tank 51 at both ends of the second elastic gasket 516.

[0041] When cleaning fluid needs to be squeezed out, the infusion port 511 needs to be sealed first, and the storage tank 51 forms a closed space. The arc-shaped part 544 abuts against the moving rod 54. Since the contact point of the arc-shaped part 544 against the moving rod 54 gradually moves away from the rotation center of the first drive shaft 41, the moving rod 54, under the action of the second spring 543 and the arc-shaped part 544, will continuously drive the abutting part 541 to repeatedly squeeze the first air bag 513 when the first drive shaft 41 rotates. When the abutting part 541 abuts against the first air bag 513, it will block the second through hole 515, thereby increasing the air pressure. The gas can push the first elastic pad 522 up, and the first elastic pad 522 will deform in the middle. Except for the two ends fixed by the first connecting part 523, the edges of the first elastic pad 522 are far away from the shell 1. Thus, air can enter the storage tank 51, increasing the pressure inside the storage tank 51. At this time, the second one-way ventilation device 514 can squeeze out the cleaning fluid in the same way.

[0042] When the abutment 541 is retracted by the second spring 543, the second through hole 515 is no longer blocked, and air re-enters the first airbag 513. Since the second elastic gasket 516 is in contact with the inner wall of the liquid storage tank 51, it cannot deform, so air or cleaning fluid cannot flow out.

[0043] When welding is not required, the infusion port 511 can be opened to prevent waste of cleaning fluid. The reservoir 51 will no longer form a closed space. At this time, the gas introduced into the reservoir 51 from the first airbag 513 will be discharged through the infusion port 511 without increasing the pressure inside the reservoir 51.

[0044] Furthermore, the scraper 53 is triangular in shape with its tip facing the first through hole 52, and the scraper 53 is also fixedly connected to a second airbag 55 which is fixedly connected to the housing 1.

[0045] When the second airbag 55 is fully inflated, the lowest point of the scraper 53 is at the same level as the first tire 42 and the second tire 44.

[0046] The shape of the scraper blade 53 allows the cleaning fluid to flow easily from the area to be welded to both sides, reducing cleaning fluid residue at the area to be welded. When the robot is not in use, the second airbag 55 can be deflated to prevent the scraper blade 53 from contacting the ground or workpiece, reducing wear on the scraper blade 53. In addition, after the second airbag 55 is inflated, if the scraper blade 53 comes into contact with a protrusion, the second airbag 55 can deform, thereby providing cushioning and protecting the scraper blade 53.

[0047] Furthermore, the top of the housing 1 is provided with multiple connection holes 7 for cables to be inserted, and the connection holes 7 are detachably connected to seals 8.

[0048] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
