DETAILED DESCRIPTION

[0023] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] The present application discloses a laser welding tool, referring to Figure 1 、 Figure 2 and Figure 3, including a cabinet 1, in which a mounting frame 2 is rotatably provided, and the rotating shaft of the mounting frame 2 is horizontal. Two first mounting plates 3 for respectively placing the parts to be welded are provided on the mounting frame 2 in a horizontal linear sliding manner, and a clamping member 4 for fixing the parts is provided on the first mounting plate 3. A first driving member 21 for driving the mounting frame 2 to rotate is provided on the cabinet 1, and a second driving member 31 for driving the two first mounting plates 3 to move is provided on the mounting frame 2. A bracket 5 is movably provided above the mounting frame 2 in the cabinet 1, and a second mounting plate 6 is vertically slidably provided on the bracket 5, and a laser welder 7 is provided on the second mounting plate 6. A third driving member 61 for driving the second mounting plate 6 to move is provided on the bracket 5, and the bracket 5 is connected to the cabinet 1 through a three-dimensional linear module 8.

[0025] In an embodiment of the present application, the staff can place the two parts to be welded on the two first mounting plates 3 respectively, and then fix them by the clamping piece 4. Then, the two first mounting plates 3 are moved to make the welding parts of the two parts contact. Then, the three-dimensional linear module 8 can be used to drive the bracket 5 to move in three-dimensional space, so that the laser welder 7 can be moved above the welding part. Finally, the second mounting plate 6 is moved down, and the laser welder 7 can weld the welding parts of the two parts. After the welding of one side of the welding part is completed, the laser welder 7 is moved up, the mounting frame 2 is rotated and the part is turned over, and the other side of the welding part of the part can be welded. A laser welding tool of the present application does not require the staff to manually turn over and weld the workpiece, and has the effect of improving the welding efficiency of the workpiece.

[0026] In an embodiment of the present application, the first driving member 21 includes a first driving motor and a driving wheel. The driving wheel is rotatably arranged on the side wall of the cabinet 1 and is connected to one end of the mounting frame 2 through a transmission belt. The first driving motor is arranged on the side wall of the cabinet 1, and the output shaft of the first driving motor is connected to the driving wheel. Starting the first driving motor can drive the driving wheel to rotate and drive the mounting frame 2 to rotate through the transmission belt.

[0027] The second drive member 31 includes a second drive motor and a bidirectional screw. The bidirectional screw is rotatably mounted on the mounting frame 2, and the two first mounting plates 3 are respectively threadedly connected to the two threaded segments of the bidirectional screw. The second drive motor is mounted at one end of the mounting frame 2 and is in driving connection with the bidirectional screw. Activating the second drive motor causes the two first mounting plates 3 to move toward each other.

[0028] The third driving member 61 includes a first driving cylinder, which is disposed on the bracket 5 . The piston rod of the first driving cylinder is vertically downward and is bolted to the second mounting plate 6 .

[0029] Reference Figure 4The clamping member 4 includes a clamping plate 41, and a mounting frame 42 for accommodating parts is bolted to the first mounting plate 3. The clamping plate 41 is linearly slidably arranged in the mounting frame 42, and a fourth driving member 43 is provided on the mounting frame 42 for driving the clamping plate 41 to move and abut against the parts.

[0030] In the embodiment of the present application, the fourth driving member 43 comprises an electric push rod, which is disposed on a side of the mounting frame 42 away from the first mounting plate 3. The movable end of the electric push rod extends into the inner side of the mounting frame 42 and connects to the clamping plate 41. After the part is placed in the mounting frame 42, the electric push rod is activated to drive the clamping plate 41 to move and abut the part, thereby securing the part.

[0031] Furthermore, a V-shaped notch 411 is formed on a side of the clamping plate 41 that contacts the parts.

[0032] In the embodiment of the present application, when the clamping plate 41 abuts against the part, the part can be positioned in the middle of the clamping plate 41 through the V-shaped notch 411, thereby improving the convenience of installing the part.

[0033] Furthermore, the mounting frame 42 is rotatably mounted on the first mounting plate 3, with the mounting frame 42's axis of rotation horizontally and perpendicular to the direction of movement of the first mounting plate 3. An adjustment member 9 is provided on the first mounting plate 3 for adjusting the rotation angle of the mounting frame 42. The adjustment member 9 includes an adjustment bolt 91. A threaded hole sized to accommodate the adjustment bolt 91 is provided on the first mounting plate 3. The mounting frame 42 is provided with a strip-shaped hole 421 perpendicular to its rotational direction. The adjustment bolt 91 passes through the strip-shaped hole 421 and is then threaded into the threaded hole. An elastic member 92 is sleeved around the outer side of the adjustment bolt 91, which is used to drive the mounting frame 42 to rotate and force the movable end of the mounting frame 42 to abut against the nut of the adjustment bolt 91.

[0034] In this embodiment, the elastic member 92 is a spring, with its ends respectively contacting the first mounting plate 3 and the mounting frame 42. The selected spring force ensures that the movable end of the mounting plate always contacts the nut of the adjustment bolt 91. Turning the adjustment bolt 91, in conjunction with the elastic member 92, rotates the mounting frame 42, adjusting the angle between the mounting frame 42 and the first mounting plate 3. This, in turn, adjusts the angle between the welded portions of the two parts, accommodating welding workpieces of various shapes and structures. This effectively enhances the versatility of the present tooling.

[0035] In order to further improve the installation stability of the parts in the installation frame 42, a plurality of installation holes are spaced apart on one side of the installation frame 42 close to the V-shaped notch 411. A vacuum suction cup 10 is provided in the installation hole for adsorbing and fixing the parts, and one end of the vacuum suction cup 10 is connected to a vacuum pump (not shown in the figure).

[0036] In the embodiment of the present application, the vacuum cup 10 is connected to the vacuum pump via a soft air tube. After the clamping plate 41 moves and abuts the part, the vacuum cup 10 contacts one side of the part, and the vacuum pump is activated to enable the vacuum cup 10 to absorb and fix the part, thereby improving the fixing effect on the part.

[0037] After the welding work is completed, the weld position of the workpiece will be raised. In order to avoid the weld protruding too much and affecting other processes such as subsequent spraying, a grinding device for grinding the weld is provided on the bracket 5. Figure 5 The grinding device includes a grinder 20, a third mounting plate 30 is vertically slidably provided on the bracket 5, the grinder 20 is arranged on the third mounting plate 30, the bracket 5 is provided with a fifth driving member 301 for driving the third mounting plate 30 to move, and the third mounting plate 30 is also provided with a cleaning device for cleaning grinding debris at the weld.

[0038] In this embodiment, the fifth drive member 301 comprises a second drive cylinder mounted on the bracket 5. The piston rod of the second drive cylinder faces vertically downward and is bolted to the third mounting plate 30. After the workpieces are welded, the laser welder 7 moves upward and the grinder 20 moves downward to grind the weld. Debris generated during grinding can be removed by a cleaning device.

[0039] Specifically, the cleaning device includes a nozzle 40 for ejecting air and blowing away grinding debris. The nozzle 40 is disposed on the third mounting plate 30 , and one end of the nozzle 40 is externally connected to a blower (not shown in the figure) for air supply.

[0040] In the embodiment of the present application, the nozzle 40 is connected to the blower through another soft air pipe. During the process of grinding the weld, the air discharged from the nozzle 40 can blow away the grinding debris near the weld.

[0041] In order to facilitate the discharge of debris generated by grinding, a discharge port 11 is opened on one side of the cabinet body 1. The inner bottom wall of the cabinet body 1 is inclined, and the lowest point of the inner bottom wall is connected to the discharge port 11.

[0042] In the embodiment of the present application, the grinding debris is blown away by the nozzle 40 and can fall on the inner bottom wall of the cabinet 1, and is discharged from the discharge port 11 along the inclined inner bottom wall, so that the staff can clean it up.

[0043] After welding, parts of the welded portion of a workpiece may experience weld leaks. To address this issue, a weld leak detection device 50 is installed within the cabinet 1. This device includes a camera 501 and a display screen 502. A fourth mounting plate 503 is mounted horizontally and linearly above the mounting frame 2 within the cabinet 1, and the camera 501 is mounted on this plate. A sixth drive element is installed on the cabinet 1 to move the fourth mounting plate 503. The display screen 502 is mounted on the outer wall of the cabinet 1.

[0044] In this embodiment, the sixth drive element comprises a third drive cylinder, which is horizontally mounted on the side wall of the cabinet 1. The piston rod of the third drive cylinder is bolted to the fourth mounting plate 503. After the workpiece is welded, the fourth mounting plate 503 is moved, allowing the camera 501 to be positioned above the workpiece. The camera 501 can then photograph the weld seam and display the weld status on the display screen 502. If a weld leak occurs, the laser welder 7 can be used to promptly perform a repair.

[0045] A cabinet door 12 is provided on one side of the cabinet body 1 . In order to facilitate the staff to observe the actual welding situation in the cabinet body 1 and to prevent the strong welding light from damaging the staff's eyes, a filter 60 is provided on the cabinet door 12 .

[0046] The implementation principle of a laser welding tool in an embodiment of the present application is as follows: the staff can place the two parts to be welded on the two first mounting plates 3 respectively, and then fix them with the clamping parts 4. Then, the two first mounting plates 3 are moved to make the welding parts of the two parts contact. Then, the three-dimensional linear module 8 can be used to drive the bracket 5 to move in three-dimensional space so that the laser welder 7 can be moved above the welding part. Finally, the second mounting plate 6 is moved down, and the laser welder 7 can weld the welding parts of the two parts. After the welding of one side of the welding part is completed, the laser welder 7 is moved up, the mounting frame 2 is rotated and the part is turned over, and the other side of the welding part of the part can be welded. There is no need for the staff to manually turn the workpiece over and weld, which has the effect of improving the welding efficiency of the workpiece.
