Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, and particularly to a welding system and its working method. Background Art

[0002] Grinding is a common processing method, mainly by rubbing a rough object such as sandpaper against a workpiece to change the physical properties of the workpiece surface. On the one hand, after the workpiece is ground, the smooth coating surface can be ground to a certain roughness, which can enhance the adhesion of the coating; on the other hand, after the workpiece is ground, burrs, rust, oil stains, etc. on the workpiece surface can be removed, so as to obtain a flat surface for subsequent processing of the workpiece.

[0003] Currently, during the welding process, in order to improve the welding effect, a grinding device is usually used to grind the area of the workpiece to be welded, so as to remove rust, dust, etc. on the workpiece surface, making the connection closer during welding. When the workpiece is ground, a grinding device is used for grinding operations. During the grinding process, a cylinder is usually used to drive the grinding mechanism to approach the workpiece for grinding. After the grinding is completed, the cylinder is used to drive the grinding mechanism away from the workpiece. However, during the process of using the cylinder to drive the grinding mechanism to move, due to the large weight of the grinding mechanism, when the cylinder drives the grinding mechanism to move to abut against the workpiece for grinding, the grinding mechanism will exert a large force on the telescopic end of the cylinder, and there is no way to exert a reverse force on the telescopic end of the cylinder to offset it, resulting in the cylinder being easily damaged due to excessive force.

[0004] In addition, in the prior art, especially during the welding process of steel plates, welding and grinding are carried out separately. And most of them are carried out by manual operation. In this way, not only is the efficiency low, but also personnel safety accidents are likely to occur due to misoperation. Summary of the Invention

[0005] One advantage of the present invention is to provide a welding system and its working method. With the welding system, not only can the workpiece be automatically ground, but also the ground workpiece can be automatically welded.

[0006] Another advantage of the present invention is to provide a welding system and its working method. When grinding the workpiece, the welding system can offset part of the force exerted by the grinding component on the belt moving component, thereby achieving the effect of relieving force, avoiding damage to the belt moving component due to excessive force, and increasing the service life of the grinding component.

[0007] One advantage of the present invention is to provide a welding system. During the process of grinding the workpiece with the welding system, the position of the grinding component can be adjusted, thereby adjusting the grinding area of the grinding component on the workpiece.

[0008] One advantage of the present invention is to provide a welding system. During the process of grinding a workpiece with the welding system, the workpiece to be ground can be fixed by the weight of the grinding assembly itself, thereby preventing the workpiece from shaking during the grinding process.

The basic principles defined in the following description of the present invention can be applied to other implementation manners, variant schemes, improvement schemes, equivalent schemes, and other technical schemes without departing from the spirit and scope of the present invention.

[0033] Those skilled in the art should understand that in the disclosure of the present invention, the orientation or positional relationships indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on the present invention.

[0034] It can be understood that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "a" should not be construed as a limitation on the number.

[0035] Referring to Figures 1 to 7 , a welding system according to a preferred embodiment of the present invention will be elaborated in detail below. The welding system includes a grinding device 100 and a welding device 200. The grinding device 100 is used to grind a workpiece 900 such as a steel plate. The welding system includes a device main body 10, at least one grinding assembly 20, a belt conveying assembly 30, and a supporting member 40.

[0036] The device main body 10 includes a support beam 11 and a carrier 12, wherein the support beam 11 is supported at a predetermined height above the carrier 12. When grinding the workpiece 900, the workpiece 900 is placed on the carrier 12, and a moving space 1001 is formed between the support beam 11 and the carrier 12. The grinding assembly 20 is movably mounted on the support beam 11 within the moving space 1001. The supporting member 40 is mounted on the grinding assembly 20.

[0037] Specifically, the grinding assembly 20 is movably mounted on the belt moving assembly 30, and the belt moving assembly 30 is configured to drive the grinding assembly 20 to move in a direction approaching or departing from the carrier 12 from the support beam 11.

[0038] The grinding assembly 20 includes a grinding driving member 21 and a grinding member 22. The grinding member 22 is rotatably mounted on the grinding driving member 21 so that the grinding driving member 21 can drive the grinding member 22 to rotate, thereby grinding the workpiece 900.

[0039] The grinding member 22 has a grinding state and a non-grinding state. When the grinding member 22 is in the non-grinding state, the grinding member 22 is away from the carrier 12 and does not abut against the workpiece 900 placed on the carrier 12, so the workpiece 900 is not ground. When the grinding member 22 is in the grinding state, the grinding member 22 moves from the support beam 11 towards the carrier 12, the grinding member 22 approaches the carrier 12 and contacts the workpiece 900 placed on the carrier 12 to grind the workpiece 900 placed on the carrier 12.

[0040] Please refer to Figures 4 to 6 , the supporting member 40 includes a mounting body 41, a buffer member 42 and a movable member 43. The mounting body 41 is mounted on the grinding assembly 20. The buffer member 42 is mounted between the mounting body 41 and the movable member 43 in such a way that the movable member 43 is kept moving in a direction tending to move from the vertical direction towards the workpiece 900. That is to say, the movable member 43 is movably mounted on the mounting body 41. In the non-grinding state, the distance between the movable member 43 and the carrier 12 is less than the distance between the grinding member 22 and the carrier 12. Therefore, when the belt moving assembly 30 drives the grinding member 22 to grind, the movable member 43 first contacts the workpiece 900, and then the grinding member 22 contacts the workpiece 900.

[0041] In other words, when the grinding member 22 is in the grinding state, the grinding member 22 moves along the support beam 11 towards the carrier 12, the grinding member 22 approaches the carrier 12, and the movable member 43 contacts the workpiece 900. The workpiece 900 exerts pressure on the movable member 43, and the movable member 43 moves upward under the action of the pressure, and the buffer member 42 is compressed, so as to play a buffering role when the movable member 43 collides with the workpiece 900.

[0042] In other words, if the supporting member 40 is not provided, during the grinding process of the belt moving assembly 30, the grinding member 22 will directly collide with the workpiece 900, and the force exerted by the grinding assembly 20 on the belt moving assembly 30 cannot be offset. Moreover, the weight of the grinding assembly 20 is usually relatively large. Therefore, when the belt moving assembly 30 drives the grinding driving member 21 to move, the grinding assembly 20 will exert a relatively large force on the belt moving assembly 30, resulting in a reduced service life of the belt moving assembly 30. After the supporting member 40 is provided, it can play a buffering role. More importantly, when the grinding assembly 20 is working, the supporting member 40 can press the overall weight of the grinding assembly 20 on the workpiece 900 to press the workpiece 900 tightly against the device main body 10, thereby effectively preventing the workpiece 900 from shaking and ensuring the accuracy of the ground part on the workpiece 900. That is to say, the present application does not need to additionally provide a device for pressing the workpiece 900.

[0043] Preferably, the grinding driving member 21 is implemented to include a motor, and the grinding member 22 is implemented to include a thousand-wheel, so as to drive the thousand-wheel to rotate synchronously through the motor to grind the workpiece 900.

[0044] More preferably, the grinding assembly 20 further includes a cover body 23, the cover body 23 is sleeved outside the grinding driving member 21, and the supporting member 40 is installed on the cover body 23.

[0045] In one embodiment, the belt moving assembly 30 is implemented to include a cylinder, and the grinding assembly 20 is movably installed on the moving end of the cylinder, and the grinding assembly 20 is driven to move synchronously by the telescopic movement of the cylinder.

[0046] Please refer to Figures 2 to 3 . In another embodiment, the belt moving assembly 30 includes a first driving member 31, a first belt moving member 32 and a first guide rail 33. The first belt moving member 32 is installed on the first guide rail 33, the first driving member 31 drives the first belt moving member 32 to move, and the grinding assembly 20 is movably installed on the first belt moving member 32.

[0047] Preferably, the first driving member 31 is implemented to include a motor, the first belt moving member 32 is implemented to include a lead screw and a slider, the lead screw and the slider are connected by a thread, the slider is slidably mounted on the first guide rail 33, and the first driving member 31 drives the lead screw to rotate, so as to drive the slider to slide along the first guide rail 33 by the rotation of the lead screw, thereby driving the movement of the grinding assembly 20.

[0048] In one embodiment, the mounting body 41 has a mounting cavity 4101, the movable member 43 is inserted into the mounting body 41 through the mounting cavity 4101, and the buffer member 42 is disposed between the top of the movable member 43 and the top wall of the mounting cavity 4101, so that when the movable member 43 is subjected to pressure, the movable member 43 moves downward and compresses the buffer member 42.

[0049] In another embodiment, the buffer member 42 is sleeved on the mounting body 41, the movable member 43 has a jack, and the movable member 43 is inserted into one end of the mounting body 41 away from the buffer member 42 through the jack. In this way, when the movable member 43 contacts the workpiece 900, the movable member 43 is pushed to move downward along the mounting body 41 and the buffer member 42 is squeezed.

[0050] Furthermore, the grinding device 100 further includes a position adjustment assembly 50, the position adjustment assembly 50 is mounted on the belt moving assembly 30, and the position adjustment assembly 50 is configured to drive the belt moving assembly 30 to move along the horizontal extension direction of the support beam 11.

[0051] In one embodiment, the position adjustment assembly 50 is implemented to include a cylinder, the belt moving assembly 30 is mounted on the moving end of the cylinder, and the telescopic movement of the cylinder is used to push the belt moving assembly 30 to move in the horizontal direction of the support beam 11, and the grinding assembly 20 is mounted on the belt moving assembly 30, thereby driving the grinding assembly 20 to move synchronously, and further adjusting the grinding position of the grinding assembly 20.

[0052] In another embodiment, the position adjustment assembly 50 includes a second driving member 51, a second belt moving member 52 and a second guide rail 53, the second belt moving member 52 is mounted on the second guide rail 53, the second driving member 51 drives the second belt moving member 52 to move, the belt moving assembly 30 is movably mounted on the second belt moving member 52, and the second guide rail 53 extends in the horizontal direction.

[0053] Preferably, the second driving member 51 is implemented to include a motor, the second belt moving member 52 is implemented to include a gear, a rack and a slider, the gear and the rack are meshed with each other, the slider is slidably mounted on the second guide rail 53, the first driving member is mounted on the slider, the gear is connected to the second driving member 51, and the second driving member 51 drives the gear to rotate clockwise or counterclockwise.

[0054] In this way, the second driving member 51 drives the gear to rotate clockwise or counterclockwise. Since the gear and the rack are meshed with each other, when the second driving member 51 drives the gear to rotate, the gear will move horizontally along the rack, thereby driving the slider to move along the rack as a whole. And the belt moving assembly 30 is mounted on the slider, so as to drive the belt moving assembly 30 to move synchronously in the horizontal direction, and further adjust the position of the belt moving assembly 30, and finally change the area of the workpiece 900 polished by the belt moving assembly 30.

[0055] Further, the grinding device 100 further includes a controller 60. The belt moving assembly 30 and the grinding driving member 21 are controllably connected to the controller 60. The controller 60 controls the start and stop of the grinding driving member 21 and the belt moving assembly 30, so as to control the automatic grinding of the grinding member 22 and the movement of the belt moving assembly 30.

[0056] Further, the grinding device 100 further includes at least one displacement sensor 70. The displacement sensor 70 is arranged to be able to detect the position of the grinding member 22. The displacement sensor 70 is communicatively connected to the controller 60. When the displacement sensor 70 detects that the grinding member 22 moves a preset length, a signal is transmitted to the controller 60. After receiving the signal, the controller 60 controls the belt moving assembly 30 to stop moving further, so as to avoid the continuous movement of the grinding assembly 20 from affecting the grinding effect.

[0057] Preferably, the displacement sensor 70 is mounted on the carrier table 12.

[0058] Further, the grinding device 100 further includes a conveying device 80. The conveying device 80 is arranged to be movably mounted on the carrier table 12. The conveying direction of the conveying device 80 is parallel to the extending direction of the first guide rail 33. In this way, when grinding, the workpiece 900 is placed on the conveying device 80, and the conveying device 80 is used to convey the workpiece 900, so that during the grinding of the workpiece 900, the conveying device 80 drives the workpiece 900 to move synchronously, and there is no need to manually transfer the workpiece 900, which is more time-saving and labor-saving.

[0059] In one embodiment, the conveying device 80 is implemented to include conveying rollers, and the conveying device 80 is disposed on the bearing table 12. The workpiece 900 is placed on the conveying rollers for conveyance. The welding device 200 is erected on both sides of the conveying device 80 so that after the workpiece 900 is polished, the workpiece 900 can be conveyed to the welding device 200 by the conveying device 80 for welding.

[0060] According to another aspect of the present invention, the present invention provides a working method of a welding system, which includes the following steps:

[0063] The position adjustment assembly 50 pushes the belt moving assembly 30 to move in the horizontal direction, adjusts the position of the belt moving assembly 30, and thus changes the area where the belt moving assembly 30 grinds the workpiece 900. The working method of the welding system further includes the following steps:

[0064] The workpiece 900 can be conveyed to the welding device 200 by the conveying device 80 for welding.

[0065] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention.
