Therefore, the development of an industrial robot device that can automatically complete welding operations is of great significance to improving welding efficiency and quality.

[0003] However, there are still some defects in the automatic welding devices of some industrial robots on the market. For example, in the Chinese patent with the publication number of "CN 220006519 U", an automatic welding device based on an industrial robot control system is disclosed, which includes a base, a welding robot arm and a processing table, wherein the welding robot arm is fixedly arranged on one side of the upper surface of the base, and a support column is fixedly connected to the upper surface of the base near the welding robot arm; the processing table is rotatably arranged on the top of the support column; a support plate is arranged above the processing table, a support rod is arranged between the support plate and the base and is fixedly connected by the support rod, and a shielding mechanism that slides left and right is arranged between the support plate and the processing table, and the shielding mechanism includes a transparent shielding plate that moves up and down, and the transparent shielding plate is an arc structure, and the bottom surface of the transparent shielding plate is connected in abutment with the top surface of the processing table. When the device is used, the shielding of the transparent shielding plate can prevent sparks generated during welding from splashing onto the observer. Although the shielding structure can be rotated, since the welding robot is fixed, there will be a blind spot when the device shields the sparks generated during welding, and the use range of the device is limited.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in 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 in 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-Figure 11 As shown, the utility model provides the following technical solutions:

[0033] An automatic welding device of an industrial robot is used to weld workpieces, such as Figure 1-Figure 8 As shown, the device includes a welding member 3 for welding a workpiece, and also includes a fixing member 4, and a clamping space for clamping the workpiece is formed at the bottom of the fixing member 4;

[0034] In addition, in the present invention, when the device is welding a workpiece, in order to shield sparks generated during welding, the device further includes a shielding member 2 that moves up and down relative to the fixing member 4 , and the fixing member 4 is located above the shielding member 2 .

[0035] In order to adjust the shielding position of the shielding member 2, in the present invention, the device also includes a driving member 5, which is located below the shielding member 2, and the driving member 5 includes a rotating plate 51 that rotates along a preset axis. The shielding member 2 is open to one side of the welding member 3 to form a shielding space for shielding the workpiece, and the shielding member 2 and the welding member 3 are fixed to the top of the rotating plate 51 along the length direction of the rotating plate 51.

[0036] Through the above technical scheme, when personnel need to weld the workpiece, the workpiece to be welded is placed in the clamping space on the fixing member 4 for fixing. After the workpiece is fixed, the fixing member 4 is moved downward relative to the shielding member 2 until the fixing member 4 drives the workpiece to move into the shielding space inside the shielding member 2. The driving member 5 works to make the rotating plate 51 rotate along the preset axis, so that the rotating plate 51 drives the shielding member 2 and the welding member 3 to rotate synchronously, thereby adjusting the angle of the welding member 3 close to the workpiece. After the angle of the welding member 3 and the shielding member 2 is adjusted, the welding member 3 is worked to make the welding member 3 weld the workpiece. When the welding member 3 welds the workpiece, the shielding member 2 is used to shield the sparks generated during the welding work of the welding member 3.

[0037] In addition, in the present invention, when the device is working, in order to make the device more stable, the welding device further includes a support member 1 , and the driving member 5 is installed on the support member 1 .

[0038] In this embodiment, the driving member 5 and the fixing member 4 are supported by the supporting member 1, so that the device is more stable when working.

[0039] In addition, in the present invention, regarding the above-mentioned support member 1, as Figure 1-Figure 5 and Figure 8 As shown, the support member 1 includes a support plate 12 , the bottom of the support plate 12 is fixedly connected to a support leg 11 , and the top of the support plate 12 is sunken to form a top groove 13 .

[0040] In this embodiment, the support plate 12 is placed at the position required by the personnel, and the support plate 12 is supported by the support legs 11 so that the support plate 12 is placed stably, and the driving member 5 is supported by the support plate 12. When the personnel need to weld the workpiece, the workpiece to be welded is placed in the clamping space on the fixing member 4 for fixing. After the workpiece is fixed, the fixing member 4 is moved downward relative to the shielding member 2 until the fixing member 4 drives the workpiece to move into the shielding space inside the shielding member 2. The driving member 5 works, and then the rotating plate 51 is rotated along the preset axis, so that the rotating plate 51 drives the shielding member 2 and the welding member 3 to rotate synchronously, and then the angle of the welding member 3 close to the workpiece is adjusted. When the angle of the welding member 3 and the shielding member 2 is adjusted, the welding member 3 is worked, and then the welding member 3 is welded to the workpiece. When the welding member 3 welds the workpiece, the shielding member 2 is used to shield the sparks generated during the welding work of the welding member 3.

[0041] Regarding how the driving member 5 drives the shielding member 2 to rotate, Figure 1-Figure 5 As shown, the driving member 5 includes a motor 52, which is fixedly connected to the bottom of the support plate 12, and the output end of the motor 52 is connected to an output shaft 53, which rotates through the support plate 12, and the top of the support plate 12 is fixedly connected to the bottom of the rotating plate 51.

[0042] In this embodiment, the workpiece to be welded is placed in the clamping space on the fixing member 4 for fixing. After the workpiece is fixed, the fixing member 4 is moved downward relative to the shielding member 2 until the fixing member 4 drives the workpiece to move into the shielding space inside the shielding member 2. The motor 52 is operated, and the motor 52 drives the output shaft 53 to rotate along the preset axis, so that the output shaft 53 drives the rotating plate 51, the shielding member 2 and the welding member 3 to rotate synchronously, and then adjusts the angle of the welding member 3 close to the workpiece. When the angle of the welding member 3 and the shielding member 2 is adjusted, the welding member 3 is operated, and then the welding member 3 is welded to the workpiece. When the welding member 3 welds the workpiece, the shielding member 2 is used to shield the sparks generated during the welding work of the welding member 3.

[0043] A support frame 14 is horizontally fixedly connected inside the top groove 13 , and the free end of the output shaft 53 rotates and penetrates the support frame 14 .

[0044] How does the shielding member 2 shield the workpiece during welding? Figure 1-Figure 4 , Figure 9-11As shown, the shielding member 2 includes a base plate 21 , a first shield 22 is fixedly connected to the top of the base plate 21 , and the base plate 21 is fixedly connected to the top of the rotating plate 51 .

[0045] In this embodiment, after the workpiece is fixed on the fixing member 4, the fixing member 4 is moved downward relative to the substrate 21 until the fixing member 4 drives the workpiece to move into the shielding space inside the first blocking cover 22, and the motor 52 is operated to drive the output shaft 53 to rotate along the preset axis, so that the output shaft 53 drives the rotating plate 51, the substrate 21, the first blocking cover 22 and the welding member 3 to rotate synchronously, thereby adjusting the angle of the welding member 3 close to the workpiece. After the angle between the welding member 3 and the substrate 21 and the first blocking cover 22 is adjusted, the welding member 3 is operated to weld the workpiece. When the welding member 3 welds the workpiece, the sparks generated during the welding operation of the welding member 3 are shielded by the substrate 21 and the first blocking cover 22.

[0046] Furthermore, in the present invention, in order to increase the range of spark shielding of the device, as Figure 9-11 As shown, the top of the first baffle 22 is recessed to form a mounting groove 26, and the second baffle 24 is slidably connected inside the mounting groove 26. A positioning screw 23 is screwed on one side of the first baffle 22, and one end of the positioning screw 23 extends to the inside of the mounting groove 26 to abut against the second baffle 24.

[0047] In the present embodiment, after the workpiece is fixed on the fixing member 4, the second blocking cover 24 is pulled to move the second blocking cover 24 inside the mounting groove 26, thereby adjusting the length of the second blocking cover 24 extending outside the first blocking cover 22. After the position of the second blocking cover 24 is adjusted, the positioning screw 23 is rotated to move one end of the positioning screw 23 into the mounting groove 26 until the positioning screw 23 abuts against the second blocking cover 24, thereby completing the fixing of the second blocking cover 24. After the position of the second blocking cover 24 is fixed, the fixing member 4 is moved downward relative to the base plate 21 until the fixing member 4 drives the workpiece to move to the shielding space inside the first blocking cover 22. In the meantime, the motor 52 works, and then the motor 52 drives the output shaft 53 to rotate along the preset axis, so that the output shaft 53 drives the rotating plate 51, the substrate 21, the first baffle 22, the second baffle 24 and the welding part 3 to rotate synchronously, and then adjusts the angle of the welding part 3 close to the workpiece. After the angle of the welding part 3 and the substrate 21, the first baffle 22 and the second baffle 24 are adjusted, the welding part 3 works, and then the welding part 3 welds the workpiece. When the welding part 3 welds the workpiece, the sparks generated during the welding work of the welding part 3 are shielded by the substrate 21, the first baffle 22 and the second baffle 24.

[0048] When a person needs to pull the second baffle 24, in order to facilitate the second baffle 24 to be pulled, Figure 9-11 As shown, a pull ring 25 is fixedly connected to the top of the second blocking cover 24 , and a pull hole is opened on the pull ring 25 .

[0049] In this embodiment, the second baffle 24 is facilitated to be pulled by pulling the crotch and the pull ring 25 .

[0050] In addition, in the present invention, regarding how the welding piece 3 welds the workpiece, such as Figure 9-11 As shown, the welding part 3 includes a welding robot 32 , the bottom of the welding robot 32 is fixedly connected to a side plate 31 , and the bottom of the side plate 31 is fixedly connected to the top of the rotating plate 51 .

[0051] In the present embodiment, the welding robot 32 is supported by the side plate 31 , and the welding robot 32 welds the workpiece.

[0052] Regarding how the fixing member 4 supports the workpiece, Figure 1-Figure 3 , Figure 6-Figure 7 As shown, the fixing member 4 includes a top frame 42, which is fixedly connected to the top of the support plate 12, and an electric push rod 41 is fixedly connected to the top of the top frame 42, a movable plate 46 is installed at the telescopic end of the electric push rod 41, and two bottom plates 45 are symmetrically fixedly connected to the bottom of the movable plate 46, and the two bottom plates 45 are both screwed and connected, and the opposite ends of the two screw rods 43 are fixedly connected to a clamping plate 47, and the two screw rods 43 are fixedly connected to a handle 44.

[0053] In this embodiment, the support plate 12 supports the top frame 42, and the top frame 42 supports the electric push rod 41. The workpiece to be processed is placed between the two clamping plates 47. The handle 44 drives the screw rod 43 to rotate, and then the screw rod 43 moves relative to the bottom plate 45. The clamping plate 47 is moved by the screw rod 43, and the clamping plate 47 is supported by the workpiece to fix the workpiece. The moving plate 46 is moved by the electric push rod 41, and the workpiece is moved to the inside of the first baffle 22 and the second baffle 24 by the moving plate 46, so that the welding robot 32 can easily weld the workpiece.
