Description

Technical Field

[0001] This utility model relates to the field of welding robot technology, and in particular to a welding robot anti-spatter device. Background Technology

[0002] Welding robots are industrial robots that perform welding (including cutting and spraying). According to the International Organization for Standardization's definition of a standard welding robot, an industrial robot is a multi-purpose, reprogrammable, automated control manipulator with three or more programmable axes used in industrial automation. To adapt to different applications, the mechanical interface of the robot's last axis is typically a connecting flange, which can be used to attach different tools or end effectors. Welding robots are industrial robots with welding clamps or welding (cutting) guns attached to the flange of their last axis, enabling them to perform welding, cutting, or thermal spraying. Currently, the automation level in the machining industry is increasing, and more and more factories are using welding robots. However, current welding robots lack protective mechanisms, which can lead to the generation of hot, flying debris during welding operations, potentially burning workers and threatening their safety. It can also cause fires, increasing the factory's fire hazard.

[0003] In existing anti-spatter devices for welding robots, when the device needs to be moved to different work areas, a large amount of manual handling is required, which consumes a lot of time and manpower, thus greatly reducing handling efficiency and limiting its practicality. Therefore, we propose an anti-spatter device for welding robots to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a welding robot anti-spatter device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A welding robot anti-spatter device includes: a welding support; two fixed protective plates are fixedly installed on the top of the welding support; two movable protective plates are disposed between the two fixed protective plates; two baffles are fixedly installed on the bottom of the welding support; a second bidirectional screw is rotatably installed between the two baffles; two drive plates are threaded to the outer side of the second bidirectional screw; two rotating rods are hinged to the outer side of each of the two drive plates; one end of each of the four rotating rods is hinged to the same fixed plate; a connecting plate is fixedly installed on the bottom of the fixed plate; four anti-slip support legs are fixedly installed on the bottom of the connecting plate; and two movable wheels are rotatably installed on the bottom of each of the two baffles.

[0007] Preferably, a first bidirectional screw is rotatably installed inside each of the two fixed protective plates. A support frame is fixedly installed on one side of one of the fixed protective plates. A first motor is fixedly installed inside the support frame. The output end of the first motor is fixedly connected to one end of the corresponding first bidirectional screw. Two LT-type sliders are threadedly connected to the outer sides of both first bidirectional screws. A connecting block is fixedly installed on the top of each of the two movable protective plates. One end of each of the four LT-type sliders is fixedly installed on the outer side of the corresponding connecting block. A T-shaped groove is opened on the top of each fixed protective plate. The bottom of each of the four LT-type sliders is slidably connected to the corresponding T-shaped groove.

[0008] Preferably, the outer side of the second bidirectional screw is provided with two external threads with opposite directions of rotation, and a second motor is fixedly installed on the outer side of one of the baffles, and the output end of the second motor is fixedly connected to one end of the second bidirectional screw.

[0009] Preferably, a guide plate is fixedly installed between the two baffles, and the interior of both drive plates is slidably connected to the outside of the guide plate.

[0010] Preferably, a plurality of guide posts are fixedly installed at the bottom of the welding support, and the bottom ends of the plurality of guide posts are fixedly installed at the top of the connecting plate.

[0011] Preferably, each of the two first bidirectional screws has two external threads with opposite directions of rotation on its outer side, and a timing pulley is fixedly installed on the outer side of each of the two first bidirectional screws. The same timing belt is sleeved between the two timing pulleys.

[0012] In this utility model, a welding robot anti-splash device is described. By starting the second motor, the second bidirectional screw is driven to rotate, which in turn drives the drive plate, which is threadedly connected to the second bidirectional screw, to move along the guide plate. This causes the rotating rod to rotate, which in turn causes the fixed plate to move vertically. This allows the connecting plate and the anti-slip support leg to move vertically, further moving the anti-slip support leg away from the ground and making contact with the ground by the moving wheels. This facilitates movement of the device via the moving wheels, eliminating the need for extensive manual handling, thus reducing time and manpower consumption, greatly improving handling efficiency, and broadening its applicability.

[0013] In this utility model, a welding robot anti-spatter device is described. By starting a No. 1 motor, a No. 1 bidirectional screw is driven to rotate, which in turn drives a synchronous pulley to rotate. Through the cooperation between the synchronous pulley and the synchronous belt, the two No. 1 bidirectional screws rotate synchronously, which in turn drives an LT-type slider threadedly connected to the No. 1 bidirectional screw to move along a T-shaped groove. This further drives a connecting block and a movable protective plate to move along the T-shaped groove, thus facilitating the adjustment of the position of the movable protective plate and providing protection when welding workpieces of different widths.

[0014] This utility model has a reasonable structural design. The interaction between the No. 2 motor, the No. 2 bidirectional screw, the drive plate, the rotating rod, the fixed plate, the connecting plate, the anti-slip support leg, and the moving wheel facilitates the movement of the device via the moving wheel. At this time, a large amount of manual handling is not required, thereby reducing the consumption of time and manpower, and greatly improving the handling efficiency, making it more practical.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A welding robot anti-spatter device includes: a welding support 1, two fixed protective plates 3 fixedly installed on the top of the welding support 1, two movable protective plates 4 disposed between the two fixed protective plates 3, two baffles 2 fixedly installed on the bottom of the welding support 1, a second bidirectional screw 15 rotatably installed between the two baffles 2, two drive plates 16 threadedly connected to the outer side of the second bidirectional screw 15, two rotating rods 17 hinged to the outer side of each of the two drive plates 16, a fixed plate 18 hinged to one end of each of the four rotating rods 17, a connecting plate 19 fixedly installed on the bottom of the fixed plate 18, four anti-slip support legs 20 fixedly installed on the bottom of the connecting plate 19, and two movable wheels 13 rotatably installed on the bottom of each of the two baffles 2.

[0023] In this embodiment, a first bidirectional screw 6 is rotatably installed inside each of the two fixed protective plates 3. A support frame 11 is fixedly installed on one side of one of the fixed protective plates 3. A first motor 5 is fixedly installed on the inner side of the support frame 11. The output end of the first motor 5 is fixedly connected to one end of the corresponding first bidirectional screw 6. Two LT-type sliders 9 are threadedly connected to the outer sides of the two first bidirectional screws 6. A connecting block 10 is fixedly installed on the top of each of the two movable protective plates 4. One end of each of the four LT-type sliders 9 is fixedly installed on the outer side of the corresponding connecting block 10. A T-shaped groove 12 is opened on the top of each of the fixed protective plates 3. The bottom of each of the four LT-type sliders 9 is slidably connected to the corresponding T-shaped groove 12, which facilitates the adjustment of the position of the movable protective plates 4.

[0024] In this embodiment, the outer side of the second bidirectional screw 15 is provided with two external threads with opposite directions of rotation. The outer side of one of the baffles 2 is fixedly installed with a second motor 14. The output end of the second motor 14 is fixedly connected to one end of the second bidirectional screw 15 to facilitate the rotation of the second bidirectional screw 15.

[0025] In this embodiment, a guide plate 22 is fixedly installed between the two baffles 2, and the interiors of the two drive plates 16 are slidably connected to the outside of the guide plate 22. The guide plate 22 provides guidance for the movement of the drive plates 16. Multiple guide posts 21 are fixedly installed at the bottom of the welding support 1, and the bottom ends of the multiple guide posts 21 are fixedly installed at the top of the connecting plate 19. The guide posts 21 make the connecting plate 19 more stable when it moves.

[0026] In this embodiment, two external threads with opposite directions are provided on the outer sides of the two No. 1 bidirectional screws 6, and synchronous pulleys 7 are fixedly installed on the outer sides of the two No. 1 bidirectional screws 6. The same synchronous belt 8 is sleeved between the two synchronous pulleys 7, so that the two No. 1 bidirectional screws 6 can be driven to rotate synchronously through the mutual cooperation between the synchronous pulleys 7 and the synchronous belt 8.

[0027] In this embodiment, during use, starting motor 5 drives the first bidirectional screw 6 to rotate, which in turn drives the synchronous pulley 7 to rotate. The synchronous pulley 7 and synchronous belt 8 then synchronize the rotation of the two bidirectional screws 6, causing the LT-shaped slider 9, threadedly connected to the first bidirectional screw 6, to move along the T-shaped groove 12. This further moves the connecting block 10 and the movable protective plate 4 along the T-shaped groove 12, facilitating the adjustment of the position of the movable protective plate 4 and providing protection during welding of workpieces of different widths. When the device needs to be moved to different working areas, starting motor 14 drives the second bidirectional screw 15 to rotate, which in turn drives the drive plate 16, threadedly connected to the second bidirectional screw 15, to open... The device begins to move along the guide plate 22, causing the rotating rod 17 to rotate, which in turn causes the fixed plate 18 to move vertically. This causes the connecting plate 19 and the anti-slip support leg 20 to move vertically, further moving the anti-slip support leg 20 away from the ground and making contact with the ground via the moving wheel 13. This facilitates movement of the device via the moving wheel 13, eliminating the need for extensive manual handling, thus reducing time and manpower consumption and greatly improving handling efficiency and versatility. When the device moves to the designated work area, the above operation is repeated in reverse, causing the moving wheel 13 to move away from the ground and the anti-slip support leg 20 to re-contact the ground, providing stable support for the device. At the same time, the height of the device can be adjusted to facilitate the operation of different types of welding robots.
