Detailed implementation manners

[0017] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0018] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0019] Such as Figures 1 - 10A welding positioning robot for steel processing as shown includes a workbench 2. A steel part 3 is placed on the upper surface of the workbench 2. A servo drive mechanism is installed inside the workbench 2. The servo drive mechanism realizes precise position control through a servo motor and a servo control system and can be used for translational adjustment. It is an existing and mature mechanism and will not be elaborated here. Above the workbench 2, there is a fixed frame 5. Guide blocks 6 are fixedly installed on both sides of the fixed frame 5. The bottom of the guide blocks 6 cooperates with the servo drive mechanism. The fixed frame 5 is directly above the steel part 3, and the guide blocks 6 are on the sides of the steel part 3. Inside the fixed frame 5, there is a blanking mechanism 7 and a storage frame 17. A plurality of reinforcing plates 4 are stacked and installed inside the storage frame 17. The reinforcing plates 4 are used to be welded on the surface of the steel part 3. The blanking mechanism 7 cooperates with the storage frame 17. The blanking mechanism 7 can vertically install the reinforcing plates 4 on the surface of the steel part 3. A welding robot assembly 1 is installed on the side of the workbench 2. The welding robot assembly 1 is used to weld the reinforcing plates 4 on the surface of the steel part 3. Through the cooperation of the blanking mechanism 7 and the storage frame 17, automatic blanking operation of the reinforcing plates 4 is realized. And after the blanking of the reinforcing plates 4, an automatic flipping action can be completed. The reinforcing plates 4 will be adjusted to a vertical state and accurately placed on the surface of the steel part 3, making positioning preparations for the subsequent welding of the welding robot assembly 1, reducing manual intervention and improving production efficiency.

[0020] At the rear end of the bottom of the fixed frame 5, an L-shaped main body plate 8 is fixedly installed. Fixed side bars 9 are fixedly installed on both sides of the L-shaped main body plate 8. Above the L-shaped main body plate 8 and between the two fixed side bars 9, a flap 10 is movably arranged. The flap 10 is at the front end of the L-shaped main body plate 8. A gear 11 is installed at the front end of the flap 10. The end of the gear 11 is connected to the fixed side bar 9 through a rotating shaft. The fixed frame 5 serves as a structure for carrying and positioning related components. The L-shaped main body plate 8 is fixed at its bottom rear end. The two fixed side bars 9 provide a framework foundation for the installation and movement of components such as the flap 10. The flap 10 is at the front end of the L-shaped main body plate 8 and between the two fixed side bars 9. This installation method enables the flap 10 to rotate around the rotating shaft connected to the fixed side bar 9. When the reinforcing plate 4 falls from the storage frame 17 onto the surface of the flap 10, since the gear 11 is installed at the front end of the flap 10 and is connected to the fixed side bar 9 through a rotating shaft, the rotation of the gear 11 can drive the flap 10 to perform a flipping action around the rotating shaft. During the flipping process of the flap 10, the reinforcing plates 4 originally placed parallel on its surface will gradually change their postures as the flap 10 rotates and will ultimately be adjusted to a vertical state and accurately placed on the surface of the steel part 3, making positioning preparations for the subsequent welding of the welding robot assembly 1.

[0021] The width of the fixed frame 5 is greater than the width of the steel part 3, and the width of the L-shaped main body plate 8 is less than the width of the steel part 3. The L-shaped main body plate 8 is movably arranged inside the steel part 3. The width of the fixed frame 5 being greater than the width of the steel part 3 can position and delimit the range of the steel part 3 as a whole, providing a stable placement space for the steel part 3 on the workbench 2, ensuring that it will not shift randomly due to external interference during the welding process and guaranteeing the accuracy of the welding position. The width of the L-shaped main body plate 8 being less than the width of the steel part 3 and being arranged inside the steel part 3, such a layout can provide an installation foundation for components such as the turning plate 10 without hindering the normal placement of the steel part 3. At the same time, the turning plate 10 can more accurately guide the reinforcing plate 4 to the appropriate welding position on the surface of the steel part 3, reducing the positioning deviation and improving the welding quality.

[0022] An extension plate is fixedly installed at the rear end of the bottom of the storage frame 17. Two support plates 18 are installed at both ends of the bottom of the extension plate. The support plates 18 are used to support the reinforcing plate 4. A protruding plate 19 is fixedly arranged at the front end of the bottom of the storage frame 17. An output port 20 is reserved between the support plate 18 and the protruding plate 19. A groove 21 is formed at the bottom of the extension plate and between the two support plates 18. Multiple reinforcing plates 4 are stacked and stored in the storage frame 17. The reinforcing plates 4 fall due to their own gravity. The extension plate at the rear end of the bottom of the storage frame 17 and the support plates 18 at both ends work together to provide stable support for the reinforcing plates 4, enabling the reinforcing plates 4 to be neatly stacked and placed.

[0023] A convex platform 12 is fixedly installed at the middle end of the top of the turning plate 10. The two support plates 18 are respectively slidably installed on the sides of the convex platform 12. The convex platform 12 provides a sliding track and support for the support plates 18, enabling the support plates 18 to slide flexibly in a specific direction. The top of the convex platform 12 is at the same horizontal height as the top of the support plate 18. A shielding component 22 is arranged at the rear end of the convex platform 12. The shielding component 22 cooperates with the groove 21. Due to the top of the convex platform 12 being at the same horizontal height as the top of the support plate 18, when the storage frame 17 is directly above the turning plate 10, the bottom of the lowermost reinforcing plate 4 can contact both the support plate 18 and the convex platform 12 simultaneously, which can ensure the stability of the reinforcing plate 4 and prevent the reinforcing plate 4 from tilting or being unstably placed due to inconsistent support heights. When the storage frame 17 moves backward towards the turning plate 10, the shielding component 22 will shield the rear of the lowermost reinforcing plate 4, so that the lowermost reinforcing plate 4 will stay on the surface of the convex platform 12. After the storage frame 17 moves to the rear of the turning plate 10, the remaining reinforcing plates 4 will fall downward due to their own gravity.

[0024] The shielding component 22 includes a recovery groove 23, the recovery groove 23 is opened on the rear surface of the protruding platform 12, a second spring 24 is arranged inside the recovery groove 23, the top end of the second spring 24 is connected with a shielding block 25, the shielding block 25 is movably installed in the recovery groove 23 through the second spring 24, an arc surface is arranged at the rear end of the shielding block 25. In the initial state, the second spring 24 is in a natural extension state. Under the supporting action of the second spring 24, the shielding block 25 partially protrudes from the recovery groove 23, and the arc surface at its rear end is exposed outside, forming a shield for the rear of the lowermost reinforcing plate 4 in the storage frame 17. After that, when the storage frame 17 moves from the rear of the flap 10 to directly above the flap 10, the reinforcing plate 4 will contact the arc surface of the shielding block 25. Due to the design of the arc surface, the reinforcing plate 4 will generate a squeezing force on the shielding block 25, causing the shielding block 25 to overcome the elastic force of the second spring 24, compress the second spring 24 and move into the recovery groove 23, so as to provide an avoidance space for the smooth removal of the reinforcing plate 4. When the storage frame 17 moves to directly above the flap 10, the squeezing force acting on the surface of the shielding block 25 disappears, and the second spring 24 returns to its original state, pushing the shielding block 25 to protrude from the recovery groove 23 again and return to the initial position of shielding the subsequent reinforcing plates 4.

[0025] An activity groove 35 is opened on the inner wall of the fixed frame 5. A swing rod 28 is installed through a rotating shaft on the inner wall of the fixed frame 5 and above the activity groove 35. A baffle 30 is movably installed in the front of the fixed frame 5. A vertical groove 32 is opened at the front end of the fixed frame 5. A tension spring is arranged inside the vertical groove 32. A convex strip is arranged on the surface of the baffle 30, and the convex strip is slidably installed in the vertical groove 32, and the bottom of the tension spring is connected to the convex strip. A through groove 31 is opened at the top of the baffle 30, and a smooth rod 33 is movably installed inside the through groove 31. The front end of the swing rod 28 is connected to the smooth rod 33 through a rotating shaft. A convex column 29 is fixedly installed at the rear end of the swing rod 28, and the convex column 29 is movably arranged inside the activity groove 35. Extrusion blocks 36 are fixedly installed on both sides of the storage frame 17, and the upper surface of the extrusion blocks 36 is inclined. The surface of the extrusion blocks 36 is slidably installed in the activity groove 35. When the storage frame 17 moves backward towards the flap 10 inside the fixed frame 5, the extrusion blocks 36 on both sides of the storage frame 17 move together with the storage frame 17. Since the surface of the extrusion blocks 36 is slidably installed in the activity groove 35, during the sliding process of the extrusion blocks 36 in the activity groove 35, the extrusion blocks 36 will push the convex column 29 to move upward in the activity groove 35. The convex column 29 is fixedly installed at the rear end of the swing rod 28, and the movement of the convex column 29 drives the swing rod 28 to swing around the rotating shaft on the inner wall of the fixed frame 5. According to the lever principle, the other end of the swing rod 28 will move downward. Under the action of the smooth rod 33 and the through groove 31, the baffle 30 will be pushed to slide downward along the vertical groove 32. When the reinforcing plate 4 is flipped and adjusted to the vertical state, the baffle 30 can shield the surface of the reinforcing plate 4 and ensure the stability of the reinforcing plate 4 in the vertical state.

[0026] The surface of the L-shaped main body plate 8 is slidably installed with an L-shaped sliding plate 13. A rack 14 is provided at the front end of the L-shaped sliding plate 13. The front end of the L-shaped sliding plate 13 is movably installed below the flap 10. The rack 14 meshes with the gear 11. A guide post 15 is fixedly provided at the rear end of the L-shaped sliding plate 13. The guide post 15 movably penetrates the L-shaped main body plate 8. A first spring 16 is provided on the surface of the guide post 15 and between the L-shaped main body plate 8 and the L-shaped sliding plate 13. When the storage frame 17 moves backward in the fixed frame 5 towards the rear of the flap 10, the extension plate of the storage frame 17 will contact the L-shaped sliding plate 13 and exert a backward pushing force on it. Under the action of this thrust, the L-shaped sliding plate 13 slides backward along the surface of the L-shaped main body plate 8. Since the rack 14 is provided at the front end of the L-shaped sliding plate 13 and the rack 14 and the gear 11 always remain in a meshed state, the backward sliding of the L-shaped sliding plate 13 will drive the rack 14 to move backward synchronously. At this time, the linear motion of the rack 14 is converted into the circular motion of the gear 11, thereby driving the gear 11 to rotate around the rotating shaft. And the gear 11 is installed at the front end of the flap 10 and is connected to the fixed side bar 9 through the rotating shaft. Therefore, the rotation of the gear 11 will drive the flap 10 to rotate around the rotating shaft, completing the flipping of the flap 10. The guide post 15 movably penetrates the L-shaped main body plate 8, providing a stable guiding effect for the sliding of the L-shaped sliding plate 13, ensuring that the L-shaped sliding plate 13 can only slide along the direction of the guide post 15, improving the stability and accuracy of the movement. At the same time, the first spring 16 is between the L-shaped main body plate 8 and the L-shaped sliding plate 13. When the L-shaped sliding plate 13 slides backward, the first spring 16 will be compressed. When the L-shaped sliding plate 13 is not under external pressure, the L-shaped sliding plate 13 will reset. Under the action of the gear 11 and the rack 14, the flap 10 will also reset.

[0027] A cylinder 34 is installed at the rear of the fixed frame 5. The output end of the cylinder 34 is connected to the storage frame 17. A chute 26 is opened on the upper surface of the fixed side bar 9. A slide bar 27 is fixedly installed at the bottom of the support plate 18. The slide bar 27 is slidably installed in the chute 26. The cylinder 34 serves as a power source. When the cylinder 34 receives a control signal, its output end makes a telescopic movement, thereby pushing or pulling the storage frame 17 to move within the fixed frame 5, realizing precise control of the position of the storage frame 17, providing power support for the blanking and positioning of the reinforcement plate 4. The slide bar 27 at the bottom of the support plate 18 cooperates with the chute 26 opened on the upper surface of the fixed side bar 9. The slide bar 27 can slide smoothly within the chute 26, ensuring that the support plate 18 moves smoothly in a specific direction, so that the support plate 18 always maintains a good supporting and positioning relationship with the reinforcement plate 4, ensuring the stability of the reinforcement plate 4 during the conveying process.

[0028] Working principle: First, place the steel part 3 on the upper surface of the workbench 2, and the welding robot assembly 1 is installed on the side of the workbench 2 in a standby state. A plurality of reinforcing plates 4 are stacked and installed in the storage frame 17. Then, the air cylinder 34 controls its output end to extend, pushing the storage frame 17 to move directly above the flap 10 within the fixed frame 5. During the movement, the reinforcing plate 4 in the storage frame 17 will contact the arc surface of the blocking block 25, and the reinforcing plate 4 generates a squeezing force on the blocking block 25, causing the blocking block 25 to overcome the elastic force of the second spring 24, compress the second spring 24 and move into the recovery groove 23, and the reinforcing plate 4 passes through smoothly. When the storage frame 17 moves directly above the flap 10, the squeezing force acting on the surface of the blocking block 25 disappears, and the second spring 24 returns to its original state, pushing the blocking block 25 to extend out of the recovery groove 23 again to block the subsequent reinforcing plates 4. At this time, the bottom of the lowermost reinforcing plate 4 contacts both the support plate 18 and the protrusion 12 simultaneously, and is stably placed on the flap 10. The air cylinder 34 acts again, and its output end retracts, pulling the storage frame 17 to move backward relative to the flap 10 within the fixed frame 5. At this time, the blocking block 25 blocks the lowermost reinforcing plate 4, and the lowermost reinforcing plate 4 will move out of the storage frame 17 from the output port 20, so that the lowermost reinforcing plate 4 will remain on the surface of the protrusion 12. Then, the extension plate of the storage frame 17 contacts the L-shaped sliding plate 13 and generates a backward pushing force on it. The L-shaped sliding plate 13 slides backward along the surface of the L-shaped main plate 8, and the rack 14 at its front end moves backward synchronously. Since the rack 14 meshes with the gear 11, the linear motion of the rack 14 is converted into the circular motion of the gear 11, driving the gear 11 to rotate around the rotating shaft, thereby driving the flap 10 to rotate around the rotating shaft. During the rotation of the flap 10, the reinforcing plates 4 originally placed parallel on its surface will gradually change their postures as the flap 10 rotates, and finally be adjusted to an upright state. During the movement of the storage frame 17 backward relative to the flap 10, the extrusion blocks 36 on both sides of the storage frame 17 slide in the movable groove 35, pushing the convex column 29 to move upward in the movable groove 35. The convex column 29 drives the swing rod 28 to swing around the rotating shaft on the inner wall of the fixed frame 5. According to the lever principle, the other end of the swing rod 28 will move downward, and through the action of the optical rod 33 and the through groove 31, the baffle 30 is pushed to slide downward along the vertical groove 32. When the reinforcing plate 4 is rotated and adjusted to an upright state, the baffle 30 blocks the surface of the reinforcing plate 4 to ensure the stability of the reinforcing plate 4 in the upright state. Since the reinforcing plate 4 itself has a certain gravity, and when the flap 10 is in the upright state, there is still a certain distance between its bottom and the surface of the steel part 3, the reinforcing plate 4 will naturally fall after being rotated. The bottom of the reinforcing plate 4 will contact the surface of the steel part 3, and the flap 10 and the baffle 30 will clamp and position the top of the reinforcing plate 4. After the reinforcing plate 4 is erected on the surface of the steel part 3, the welding robot assembly 1 is started to perform welding operations on the bottom surface and side surface of the reinforcing plate 4 erected on the surface of the steel part 3 and located on one side of the baffle 30. After welding, the reinforcing plate 4 will be fixed on the surface of the steel part 3.After welding is completed, the air cylinder 34 pushes the stock storage frame 17 to move directly above the flap 10 in the fixed frame 5 again. The L-shaped sliding plate 13 is not under the pressure of the stock storage frame 17 and resets forward under the action of the first spring 16. Through the action of the gear 11 and the rack 14, the flap 10 also resets to the initial position, preparing for the next blanking operation of the reinforcing plate 4. Finally, the servo drive mechanism drives the fixed frame 5 to move backward of the steel part 3, realizing welding multiple reinforcing plates 4 at different positions of the steel part 3. When the blanking of the reinforcing plate 4 is completed, the welding robot assembly 1 moves in the reverse direction to weld the other end of the reinforcing plate 4.
