DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0021] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0022] The embodiment of the present application solves the technical problems of low production efficiency and unstable product quality in the prior art of manually replacing workpiece welding molds by providing a three-sided basket frame robot welding workstation.

[0023] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows: like Figure 1 As shown, the present application provides a three-sided basket frame robot welding workstation, including a mold 10, a turnover platform 20, a manipulator 30, a welder 40 and a controller 50, wherein the turnover platform 20 and the controller are located on the side of the manipulator 30, and the welder 40 is located in front of the manipulator 30. The turnover platform 20, the manipulator 30, and the welder 40 are all electrically connected to the controller 50, and 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 welder 40 includes a argon arc welder, a standard spot welder, and a medium frequency inverter DC T welder; at least two turnover platforms 20 are provided, and multiple molds 10 can be loaded with welded parts at the same time, so that while the manipulator 30 sends a mold 10 into the welder 40 for welding, another turnover platform 20 can prepare the next mold 10. In this way, seamless continuous production can be achieved, which greatly shortens the waiting time and improves the overall production efficiency.

[0024] The mold 10 on the turnover platform 20 is automatically grabbed or placed by the manipulator 30, and then the mold 10 is grabbed by the manipulator 30, and the welder 40 automatically welds the parts to be welded in the mold 10, thereby realizing automatic welding of the entire system, improving production efficiency and reducing labor costs.

[0025] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Preferably, Figure 1 , Figure 2As shown, the turnover platform 20 includes a turnover frame 21 and a mobile platform 22. The turnover frame 21 is provided with a slide rail 23. The mobile platform 22 is slidably arranged on the slide rail 23 through a slider. A first telescopic rod 24 is fixedly arranged on the turnover frame 21. The output end of the first telescopic rod 24 is fixedly connected to the mobile platform 22. The mold 10 is operably mounted on the mobile platform 22.

[0027] The mobile platform 22 is controlled to move on the turnover frame 21 by the first telescopic rod 24. When the mobile platform 22 is in the first position, that is, away from the side of the manipulator 30, it is convenient for the operator to install the workpiece to be welded in the mold 10. The mobile platform 22 moves the mold 10 carrying the workpiece to be welded to the second position, that is, close to the side of the manipulator 30, which is convenient for the manipulator 30 to grab the mold 10, thereby improving the material preparation speed and reducing labor costs.

[0028] Furthermore, a limit column 25 and a laser sensor 26 are installed on the turnover platform 20. The limit column 25 is arranged parallel to the slide rail 23, and the laser sensor 26 is arranged perpendicular to the slide rail 23. The limit column 25 and the laser sensor 26 are both installed on the turnover platform 20 through angle irons, so that the limit column 25 and the mobile platform 22 are located on the same horizontal plane, and the laser sensor 26 and the slider on the mobile platform 22 are located on the same horizontal plane.

[0029] The mobile platform 22 moves on the turnover frame 21. When the mobile platform 22 moves to the second position, the laser sensor 26 detects that the mobile platform 22 reaches the specified position, controls the first telescopic rod 24 to stop working, and enables the mobile platform 22 to move to the specified position. The limit column 25 limits the mobile platform 22, so that the positioning of the mobile platform 22 is more accurate, and the grabbing position of the mold 10 is fixed.

[0030] Preferably, Figure 3 , Figure 4 As shown, the first V-shaped groove 221 and the second V-shaped groove 222 are installed on the mobile platform 22, and the first V-shaped block 11 and the second V-shaped block 12 are installed on the bottom surface of the mold 10. Specifically, the first V-shaped block 11 is operably installed in the first V-shaped groove 221, and the second V-shaped block 12 is operably installed in the second V-shaped groove 222. The first V-shaped groove 221 is arranged parallel to the slide rail 23, and the second V-shaped groove 222 is arranged perpendicular to the slide rail 23. The first V-shaped groove 221 and the second V-shaped groove 222 can be arranged in plurality. In this embodiment, two first V-shaped grooves 221 and two second V-shaped grooves 222 are arranged respectively.

[0031] During the actual working process, the robot 30 grabs the mold 10 and places the mold 10 on the mobile platform 22. The first V-block 11 and the second V-block 12 on the mold 10 just fit into the corresponding first V-groove 221 and the second V-groove 222. Since the first V-groove 221 and the second V-groove 222 are set in different directions, the length and width directions of the mold 10 are limited, so that the mold 10 can be accurately placed on the mobile platform 22.

[0032] Further, such as Figure 5 As shown, the design of the second V-shaped groove 222 is further optimized to improve the ability to adjust the gripping 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 adjustment chamber 2221 is provided in the second V-shaped groove 222, and the adjustment chamber 2221 is connected to the second V-shaped groove 222. An adjustment block 2222 is provided in the adjustment chamber 2221, and a lead screw 2223 is further provided in the second V-shaped groove 222. The lead screw 2223 is rotatably provided on the second V-shaped groove 222, and the adjustment block 2222 is threadedly engaged with the lead screw 2223. An adjustment handle 2224 is fixedly provided 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 provided on the adjustment block 2222, a third V-shaped groove 121 is provided on the bottom surface of the second V-shaped block 12, the third V-shaped groove 121 and the third V-shaped block 2225 are operably matched, and the third V-shaped groove 121 and the third V-shaped block 2225 are both provided perpendicular to the slide rail 23.

[0033] In the actual working process, the entire welding workstation works for a long time, which can easily lead to inaccurate positioning of the manipulator 30 and the turnover platform 20, making it difficult for the manipulator 30 to grab and place the mold 10. When the manipulator 30 grabs the mold 10, it may not reach the grabbing position and the mobile platform 22 may not reach the position to be grabbed. First, the first V-block 11 and the first V-groove 221 and the second V-block 12 and the second V-groove 222 cooperate with each other, and the third V-groove 121 and the third V-block 2225 cooperate with each other. By adjusting the lead screw 2223, the adjustment block 2222 drives the third V-block 2225 to move along the track direction, and then the second V-block 12 moves in the second V-groove 222 along the direction of the slide rail 23, and the first V-block 11 moves in the first V-groove 221, thereby realizing fine-tuning of the front and rear positions of the mold 10, making the positioning of the manipulator 30 and the mold 10 more accurate and improving work efficiency.

[0034] Furthermore, Figure 5As shown, a clamping plate 2226 is provided on the inner side surface of the second V-shaped groove 222. The clamping plate 2226 is an angled plate. One side of the clamping plate 2226 is parallel to the inner side surface of the second V-shaped groove 222, and the other side of the clamping plate 2226 is parallel to the vertical surface of the second V-shaped block 12. An adjustment seat 2227 is fixedly provided on the upper end surface of the second V-shaped groove 222. A first slide bar 2228 is fixedly provided on the vertical surface of the clamping plate 2226. A first spring 2229 is provided on the first slide bar 2228. The first spring 2229 is provided between the clamping plate 2226 and the adjustment seat 2227. A second slide bar 2230 is fixedly provided on the bending surface of the clamping plate 2226. A blind hole 2231 is provided on the inner side surface of the second V-shaped groove 222. The second slide bar 2230 is slidably provided in the blind hole 2231. A second spring 2232 is provided between the second slide bar 2230 and the bottom surface of the blind hole 2231.

[0035] In actual work, first insert the second V-block 12 between the two clamps 2226. The clamp 2226 compresses the first spring 2229 and the second spring 2232 so that the second V-block 12 and the clamp 2226 can fit tightly. The angle design of the clamp 2226 can also provide support for the second V-block 12.

[0036] Further, if Figure 5 As shown, the bending surface and the vertical surface of the clamping plate 2226 are respectively provided with a first pressure sensor 27 and a second pressure sensor 28. A second telescopic rod 29 is fixedly provided on the adjustment seat 2227, and the second telescopic rod 29 passes through the adjustment seat 2227 and is fixedly connected to the clamping plate 2226. The first pressure sensor 27, the second pressure sensor 28 and the second telescopic rod 29 are all electrically connected to the controller 50.

[0037] In actual work, the first pressure sensor 27 and the second pressure sensor 28 can detect the pressure changes between the clamp plate 2226 and the second V-block 12 in real time. When the pressure detected by the first pressure sensor 27 and the second pressure sensor 28 exceeds the threshold, the controller 50 controls the adjustment of the position of the second telescopic rod 29 so that both sides of the second V-block 12 are subjected to the pressure of the clamp plate 2226, thereby keeping the mold 10 stable.

[0038] Preferably, Figure 4 , Figure 6As shown, the mold 10 includes a bottom support 13, a back support 14, a side support 15 and a grabbing portion 16. The back support 14 and the grabbing portion 16 are mounted on the bottom support 13, and the side support 15 is mounted 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. The end of the steel bar weldment is inserted into the positioning hole 171, and then the positioning piece 17 is fixed by the quick clamp 18 to achieve the fixation of the weldment. The quick clamp 18 is mounted on the side support 15, and the quick clamp 18 can operably press the positioning piece 17 onto the side support 15.

[0039] By designing the structure of the mold 10 including the bottom support 13, the back support 14, the side support 15 and the gripping part 16, and arranging the positioning piece 17 and the quick clamp 18 on the side support 15, the three-sided basket frame robot welding workstation of the present application realizes high-precision positioning and rapid fixation of the mold 10. The mounting grooves 19 on the bottom support 13 and the side support 15 ensure the precise assembly of the various components of the mold 10, and the installation of the back support 14 and the gripping 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 welded parts by pressing the positioning piece 17, thereby improving the welding accuracy.

[0040] like Figure 7 As shown, a welding system is applied to a welding workstation described in any one of the above technical solutions, and the system comprises: The control unit of the turnover platform 20 is used to control the movement of the turnover platform 20, including controlling the telescopic state of the first telescopic rod 24 and the second telescopic rod 29. The first telescopic rod 24 and the second telescopic rod 29 are telescoped as required by sending instructions through the controller 50, so as to ensure the accurate movement and positioning of the mobile platform 22 on the slide rail 23; 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 welder 40 for welding. 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 welder 40 for welding, and puts the mold 10 back to the turnover platform 20 after completion; A control unit is used to control the control unit of the turnover platform 20, the control unit of the manipulator 30 and the welding machine 40. The controller 50 receives signals from various sensors and coordinates the operation of each unit according to a preset control logic; The pressure values ​​of the first pressure sensor 27 and the second pressure sensor 28 are collected in real time, and the timestamp is recorded. For each time point, the pressure difference value of the first pressure sensor 27 and the second pressure sensor 28 is calculated; A pressure difference threshold value between the first pressure sensor 27 and the second pressure sensor 28 is set. If the pressure difference between the first pressure sensor 27 and the second pressure sensor 28 is greater than 20%, it means that the current state of the mold 10 is unstable and there is a possibility of tipping over, which is used to determine whether the mold 10 is in a stable state; The second telescopic rod 29 is set to be in a passive telescopic state. When the pressure difference between the first pressure sensor 27 and the second pressure sensor 28 is less than the pressure difference threshold, the second telescopic rod 29 moves together with the clamping plate 2226; when the pressure difference between the first pressure sensor 27 and the second pressure sensor 28 is greater than the pressure difference threshold, the second telescopic rod 29 is controlled to provide pressure to the second V-shaped block 12 to ensure the stability of the mold 10; The pressure value data of the first pressure sensor 27 and the second pressure sensor 28 are trained by the LSTM model, and the trained model is used to predict future time points to obtain the change trend of the pressure difference; The trained LSTM model is used to predict future time points, and the changing trend of the pressure difference is determined based on the prediction results. If the prediction results show 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.

[0041] 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 production efficiency and welding quality. Real-time collection and analysis of pressure sensor data, combined with the prediction function of the LSTM model, can detect and prevent the unstable state 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 shaking or offset of the mold 10, and improves the overall performance of the system and user experience.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
