[0040] In addition, the description involving "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of various embodiments can be combined with each other, but it must be based on the realization of a person of ordinary skill in the art, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the scope of protection claimed by the present application.

[0041] The technical solutions in the embodiments of the present application provide a three-side basket frame robot welding workstation, which solves the technical problems of low production efficiency and unstable product quality caused by manual replacement of workpiece welding molds in the prior art.

[0042] The technical solutions in the embodiments of the present application are as follows to solve the above technical problems:

[0043] As Figure 1As shown, the present application provides a three-edge basket frame robot welding workstation, which comprises a mold 10, a turnover platform 20, a manipulator 30, a welding machine 40 and a controller 50, the turnover platform 20 and the control are located on the side of the manipulator 30, the welding machine 40 is located on the front of the manipulator 30, the turnover platform 20, the manipulator 30 and the welding machine 40 are electrically connected with the controller 50, the mold 10 is placed on the turnover platform 20, and the manipulator 30 can be operated to grab or place the mold 10 from the turnover platform 20. The welding machine 40 comprises an argon arc welding machine, a standard spot welding machine and a medium frequency inverter direct current T welding machine; the turnover platform 20 is provided with at least two, which can simultaneously load a plurality of molds 10 for welding, so that while the manipulator 30 sends one mold 10 into the welding machine 40 for welding, the other turnover platform 20 can prepare the next mold 10. In this way, seamless continuous production can be realized, the waiting time is greatly shortened, and the overall production efficiency is improved.

[0044] The mold 10 on the turnover platform 20 is automatically grabbed or placed by the manipulator 30, then the mold 10 is grabbed by the manipulator 30, and the welding machine 40 automatically welds the welding part in the mold 10, realizing automatic welding of the whole system, improving the production efficiency and reducing the labor cost.

[0045] In order to better understand the above technical solutions, the above technical solutions will be described in detail in combination with the drawings of the specification and the specific embodiments.

[0046] Preferably, as shown in Figure 1 、 Figure 2 The turnover platform 20 comprises a turnover frame 21 and a moving platform 22, the turnover frame 21 is provided with a sliding rail 23, the moving platform 22 is slidably arranged on the sliding rail 23 through a sliding block, the turnover frame 21 is fixedly provided with a first telescopic rod 24, the output end of the first telescopic rod 24 is fixedly connected with the moving platform 22, and the mold 10 is operatively installed on the moving platform 22.

[0047] The moving platform 22 moves on the turnover frame 21 through the first telescopic rod 24, when the moving platform 22 is at a first position, i.e. away from the side of the manipulator 30, it is convenient for the operator to install the welding part in the mold 10, the moving platform 22 moves the mold 10 carrying the welding part to a second position, i.e. close to the side of the manipulator 30, which is convenient for the manipulator 30 to grab the mold 10, improves the material preparation speed and reduces the labor cost.

[0048] Further, the turnover platform 20 is further provided with a limiting column 25 and a laser sensor 26. The limiting column 25 is parallel to the slide rail 23, and the laser sensor 26 is perpendicular to the slide rail 23. Both the limiting column 25 and the laser sensor 26 are installed on the turnover platform 20 through an angle iron, so that the limiting column 25 is located at the same horizontal plane as the moving platform 22, and the laser sensor 26 is located at the same horizontal plane as the slide block on the moving platform 22.

[0049] The moving platform 22 moves on the turnover frame 21. When the moving platform 22 moves to the second position, the laser sensor 26 detects that the moving platform 22 reaches the specified position, and controls the first telescopic rod 24 to stop working, so that the moving platform 22 can move to the specified position. The limiting column 25 limits the moving platform 22, so that the positioning of the moving platform 22 is more accurate, and the grabbing position of the mold 10 is fixed.

[0050] Preferably, as shown in Figure 3 、 Figure 4 , the moving platform 22 is provided with a first V-shaped groove 221 and a second V-shaped groove 222, and the bottom surface of the mold 10 is provided with a first V-shaped block 11 and a second V-shaped block 12. Specifically, the first V-shaped block 11 is operatively installed in the first V-shaped groove 221, and the second V-shaped block 12 is operatively installed in the second V-shaped groove 222. The first V-shaped groove 221 is parallel to the slide rail 23, and the second V-shaped groove 222 is perpendicular to the slide rail 23. The first V-shaped groove 221 and the second V-shaped groove 222 can be provided in multiple numbers. In the embodiment, two first V-shaped grooves 221 and two second V-shaped grooves 222 are provided.

[0051] In actual work process, the manipulator 30 grabs the mold 10 and places the mold 10 on the moving platform 22. The first V-shaped block 11 and the second V-shaped block 12 on the mold 10 are just matched into the corresponding first V-shaped groove 221 and second V-shaped groove 222. Because the first V-shaped groove 221 and the second V-shaped groove 222 are arranged in different directions, the length direction and the width direction of the mold 10 are limited, so that the mold 10 can be accurately placed on the moving platform 22.

[0052] Further, as shown in Figure 5As shown, the design of the second V-shaped groove 222 is further optimized to improve the adjustment of the grabbing position of the mold 10. The width of the second V-shaped groove 222 is greater than the width of the second V-shaped block 12. An adjusting chamber 2221 is arranged in the second V-shaped groove 222, and the adjusting chamber 2221 is in communication with the second V-shaped groove 222. An adjusting block 2222 is arranged in the adjusting chamber 2221. A lead screw 2223 is arranged in the second V-shaped groove 222. The lead screw 2223 is rotatably arranged in the second V-shaped groove 222. The adjusting block 2222 is threadedly connected with the lead screw 2223. An adjusting handle 2224 is fixedly arranged at one end of the lead screw 2223 extending out of the second V-shaped groove 222. A third V-shaped block 2225 is integrally arranged on the adjusting block 2222. A third V-shaped groove 121 is arranged on the bottom surface of the second V-shaped block 12. The third V-shaped groove 121 is operably connected with the third V-shaped block 2225. The third V-shaped groove 121 and the third V-shaped block 2225 are perpendicular to the slide rail 23.

[0053] In actual work process, the whole welding workstation works for a long time, which is easy to cause the inaccurate positioning of the manipulator 30 and the turnover platform 20, so that the manipulator 30 cannot smoothly grab and place the mold 10. When the manipulator 30 grabs the mold 10, the manipulator 30 may not reach the grabbing position and the moving platform 22 may not reach the position to be grabbed. First, the first V-shaped block 11 and the first V-shaped groove 221, the second V-shaped block 12 and the second V-shaped groove 222, and the third V-shaped groove 121 and the third V-shaped block 2225 are connected with each other. By adjusting the lead screw 2223, the adjusting block 2222 drives the third V-shaped block 2225 to move along the track direction, so that the second V-shaped block 12 moves along the slide rail 23 direction in the second V-shaped groove 222, and the first V-shaped block 11 moves in the first V-shaped groove 221. Thus, the front and rear positions of the mold 10 are finely adjusted, the positioning of the manipulator 30 and the mold 10 is more accurate, and the work efficiency is improved.

[0054] Further, as shown in the drawings, Figure 5 As shown, the inner side of the second V-shaped groove 222 is provided with a clamping plate 2226. The clamping plate 2226 is a bent plate. One side of the clamping plate 2226 is parallel to the inner side of the second V-shaped groove 222. The other side of the clamping plate 2226 is parallel to the vertical surface of the second V-shaped block 12. An adjusting seat 2227 is fixedly arranged on the upper end surface of the second V-shaped groove 222. A first slide rod 2228 is fixedly arranged on the vertical surface of the clamping plate 2226. A first spring 2229 is arranged on the first slide rod 2228. The first spring 2229 is arranged between the clamping plate 2226 and the adjusting seat 2227. A second slide rod 2230 is fixedly arranged on the bent surface of the clamping plate 2226. A blind hole 2231 is arranged on the inner side of the second V-shaped groove 222. The second slide rod 2230 is slidably arranged in the blind hole 2231. A second spring 2232 is arranged between the second slide rod 2230 and the bottom surface of the blind hole 2231.

[0055] In actual work, first, the second V-shaped block 12 is inserted between the two clamps 2226, the clamps 2226 compress the first spring 2229 and the second spring 2232, so that the second V-shaped block 12 can be closely attached to the clamps 2226, and the design of the folding angle of the clamps 2226 can also provide support for the second V-shaped block 12.

[0056] Further, as shown in Figure 5 , the bending surface and the vertical surface of the clamps 2226 are respectively provided with the first pressure sensor 27 and the second pressure sensor 28. The second telescopic rod 29 is fixedly arranged on the adjusting seat 2227, and the second telescopic rod 29 passes through the adjusting seat 2227 and is fixedly connected with the clamps 2226. The first pressure sensor 27, the second pressure sensor 28 and the second telescopic rod 29 are electrically connected with the controller 50.

[0057] In actual work, the first pressure sensor 27 and the second pressure sensor 28 can detect the pressure change between the clamps 2226 and the second V-shaped block 12 in real time. When the pressure detected by the first pressure sensor 27 and the second pressure sensor 28 exceeds the threshold value, the controller 50 controls the position of the second telescopic rod 29, so that the second V-shaped block 12 is pressed by the clamps 2226 on both sides, and the mold 10 is kept stable.

[0058] Preferably, as shown in Figure 4 , Figure 6 , the mold 10 includes a bottom support 13, a back support 14, a side support 15 and a grabbing part 16. The back support 14 and the grabbing part 16 are installed on the bottom support 13, and the side support 15 is installed on the bottom support 13 through a support rod 151. The bottom support 13 and the side support 15 are provided with mounting grooves 19, and the side support 15 is provided with a positioning piece 17 and a quick clamp 18. The positioning piece 17 is provided with a positioning hole 171, and the end of the steel bar welding piece is inserted into the positioning hole 171, and then the positioning piece 17 is fixed by the quick clamp 18 to realize the fixation of the welding piece. The quick clamp 18 is installed on the side support 15, and the quick clamp 18 can operatively press the positioning piece 17 tightly on the side support 15.

[0059] By designing the mold 10 structure including the bottom support 13, the back support 14, the side support 15 and the grabbing part 16, and arranging the positioning piece 17 and the quick clamp 18 on the side support 15, the three-edge basket frame robot welding workstation of the present application realizes high-precision positioning and quick fixation of the mold 10. The mounting grooves 19 on the bottom support 13 and the side support 15 ensure the accurate assembly of the components of the mold 10, and the installation of the back support 14 and the grabbing part 16 enhances the overall stability of the mold 10 and facilitates the operation of the manipulator 30. The quick clamp 18 can quickly and reliably fix the welding piece by pressing the positioning piece 17, thereby improving the welding precision.

[0060] As shown in Figure 7As shown, a welding system applied to the welding workstation in any one of the above technical solutions, the system comprises:

[0061] The turnover platform 20 control unit is used to control the movement of the turnover platform 20, including controlling the extension state of the first telescopic rod 24 and the second telescopic rod 29, sending instructions through the controller 50, and the first telescopic rod 24 and the second telescopic rod 29 are telescoped as needed to ensure accurate movement and positioning of the moving platform 22 on the slide rail 23;

[0062] The manipulator 30 control unit is used to control the manipulator 30 to grab or place the mold 10 and send the mold 10 to the welding machine 40 for welding, and the manipulator 30 accurately grabs the mold 10 from the turnover platform 20 according to the instructions of the controller 50, sends it to the welding machine 40 for welding, and places the mold 10 back on the turnover platform 20 after completion;

[0063] The control unit is used to control the turnover platform 20 control unit, the manipulator 30 control unit and the welding machine 40, the controller 50 receives signals from various sensors, and coordinates the operation of each unit according to the preset control logic;

[0064] The pressure values of the first pressure sensor 27 and the second pressure sensor 28 are collected in real time, and the time stamp is recorded, and for each time point, the pressure difference value of the first pressure sensor 27 and the second pressure sensor 28 is calculated;

[0065] The pressure difference threshold of the first pressure sensor 27 and the second pressure sensor 28 is set, for example, if the pressure difference of the first pressure sensor 27 and the second pressure sensor 28 is greater than 20%, it represents that the current state of the mold 10 is unstable, and there is a possibility of tipping over, which is used to judge whether the mold 10 is in a stable state;

[0066] The second telescopic rod 29 is set to be in a passive telescopic state, when the pressure difference of the first pressure sensor 27 and the second pressure sensor 28 is less than the pressure difference threshold, the second telescopic rod 29 moves with the clamping plate 2226; when the pressure difference of the first pressure sensor 27 and the second pressure sensor 28 is greater than the pressure difference threshold, the second telescopic rod 29 provides pressure to the second V-shaped block 12 to ensure the stability of the mold 10;

[0067] The pressure value data of the first pressure sensor 27 and the second pressure sensor 28 is trained through the LSTM model, and the trained model is used to predict future time points to obtain the change trend of the pressure difference;

[0068] Using the trained LSTM model to make predictions for future time points, based on the prediction results, the trend of pressure difference is determined, if the prediction result shows that the pressure difference will exceed the pressure difference threshold, the system adjusts the position of the second telescopic rod 29 to ensure the stability of the mold 10.

[0069] The three-sided basket frame robot welding workstation of the present application not only realizes high-precision positioning and stable fixation of the mold 10, but also significantly improves the production efficiency and welding quality. Real-time acquisition and analysis of pressure sensor data combined with the prediction function of the LSTM model can detect and prevent unstable states of the mold 10 in advance, ensuring the efficiency and reliability of the welding process. This intelligent control strategy effectively prevents product quality problems caused by mold 10 shaking or deviation, improving the overall performance and user experience of the system.
