Description

Technical Field

[0001] This application relates to the field of welding technology, and particularly to an automatic welding device. Background Art

[0002] When processing automotive parts, some parts have complex or special shapes and structures, and cannot be directly formed by die casting. After separately forming multiple workpieces, they need to be connected by welding to form parts with the required shape or structure.

[0003] In the traditional technology, two workpieces are installed and fixed to a fixture, and the relative positions of the two workpieces are maintained by the fixture. Then, a mold is held by hand and used in cooperation with a welding torch to weld the workpieces. However, there are problems that the accuracy and efficiency of manual welding are relatively low. Utility Model Content

[0004] The purpose of this application is to provide an automatic welding device to increase welding accuracy and welding efficiency.

[0005] In the first aspect, an automatic welding device provided by this application adopts the following technical solutions:

[0006] An automatic welding device includes:

[0007] A welding table for welding workpieces;

[0008] A receiving table corresponding to the welding table in position and used for temporarily storing workpieces;

[0009] A manipulator corresponding to the receiving table in position and used for clamping and moving the workpiece to the position of the welding table so that the welding table welds the workpiece;

[0010] A first conveyor belt for transporting workpieces to the receiving table;

[0011] A second conveyor belt for transporting the welded workpieces away;

[0012] A moving mechanism for moving the workpiece on the receiving table to the second conveyor belt.

[0013] By adopting the above technical solutions, first, by setting a manipulator to grab the workpiece and drive it to move to the welding table, the welding table welds the workpiece, thereby reducing the process of manual welding, increasing the welding efficiency and the welding accuracy. Second, by setting a receiving table, the workpiece is transported to the receiving table each time, ensuring that the transportation position of the workpiece is the same each time, and reducing the situation that the transportation position of the workpiece changes due to improper control of the conveyor belt, resulting in the failure of the manipulator to grab the workpiece.

[0014] Optionally, the moving mechanism includes a sliding plate and a driving component. The sliding plate is slidably connected to the receiving table and is located between the first conveyor belt and the second conveyor belt. The driving component is used to drive the sliding plate to slide reciprocally between the first conveyor belt and the second conveyor belt.

[0015] By adopting the above technical solution, the workpiece is driven to move through the sliding of the sliding plate, so as to realize the transportation of the workpiece. The structure is simple and the operation is stable.

[0016] Optionally, the driving component includes a first telescopic rod and an elastic member. One end of the first telescopic rod is arranged at the bottom end of the first conveyor belt, and the other end of the first telescopic rod can abut against the sliding plate and push the sliding plate to move;

[0017] One end of the elastic member is fixedly connected to the sliding plate, and the other end of the elastic member is connected to the receiving table.

[0018] By adopting the above technical solution, the sliding plate is driven to move through the telescopic movement of the first telescopic rod, and the sliding plate is reset through the telescopic movement of the elastic member, so as to realize the reciprocating movement of the sliding plate. The elastic member is used to provide a certain buffering and reset function during the movement of the sliding plate.

[0019] Optionally, a first guide rail and a second guide rail are arranged on the receiving table. The first guide rail and the second guide rail are symmetrically arranged. The two sides of the sliding plate are respectively slidably connected to the first guide rail and the second guide rail. The first guide rail is rotatably connected to the receiving table, and the second guide rail is lapped on the receiving table. A second telescopic rod is arranged on the receiving table. One end of the second telescopic rod is hinged to the receiving table, and the other end of the second telescopic rod is hinged to the second guide rail. The telescopic movement of the second telescopic rod is used to drive the second guide rail to move, so as to realize the rotation of the sliding plate;

[0020] The size of the sliding plate is smaller than the size of the workpiece. When the sliding plate rotates, the manipulator can grasp the back surface of the workpiece.

[0021] The fixture is composed of a frame body, a pressing plate and a locking buckle. The pressing plate is rotatably connected to the frame body, and the locking buckle is fixed on the frame body and is used to fix the pressing plate. Since the fixture presses two automotive parts through the pressing plate and then locks the pressing plate through the locking buckle, when using the clamping jaw to directly clamp the workpiece, it will directly clamp on the top pressing plate. During the movement of the workpiece driven by the manipulator, because it is directly clamped on the pressing plate, the force on the workpiece will be transmitted to the connection between the pressing plate and the locking buckle, which is likely to cause the pressing plate and the locking buckle to be separated from each other. By adopting the above technical solution, the second guide rail is driven to rotate by the second telescopic rod, so that the sliding plate rotates, thereby aligning the back surface of the workpiece with the manipulator, enabling the manipulator to directly grasp the frame body of the fixture, reducing the force on the connection between the pressing plate and the locking buckle, reducing the separation of the pressing plate and the locking buckle, and increasing the welding stability.

[0022] Optionally, there are two second telescopic rods, and the two second telescopic rods are located on the side of the sliding plate away from the welding table and are distributed at both ends of the sliding plate.

[0023] By adopting the above technical solution, the arrangement of the two second telescopic rods can provide more stable and reliable rotational power, and increase the rotational stability of the sliding plate.

[0024] Optionally, the first telescopic rod adopts an electric telescopic rod or a hydraulic telescopic rod.

[0025] By adopting the above technical solution, using an electric telescopic rod or a hydraulic telescopic rod facilitates the electric control of the first telescopic rod and increases the automation degree of the welding device.

[0026] Optionally, the second telescopic rod adopts an electric telescopic rod or a hydraulic telescopic rod.

[0027] By adopting the above technical solution, using an electric telescopic rod or a hydraulic telescopic rod facilitates the electric control of the second telescopic rod and increases the automation degree of the welding device.

[0028] Optionally, the elastic member adopts a spring.

[0029] By adopting the above technical solution, the spring has a large telescopic range, which facilitates controlling the sliding range of the sliding plate. Moreover, the spring has stable elasticity, which is convenient for purchase and replacement.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. First, by providing a manipulator to grasp the workpiece and drive the workpiece to move to the welding table, the welding table welds the workpiece, thereby reducing the manual welding process, increasing the welding efficiency and the welding precision. Second, by providing a receiving table, the workpiece is transported to the receiving table each time, ensuring that the transportation position of the workpiece is the same each time, and reducing the situation where the transportation position of the workpiece changes due to improper control of the conveyor belt, resulting in the failure of the manipulator to grasp the workpiece;

[0032] 2. The second telescopic rod drives the second guide rail to rotate, causing the sliding plate to rotate, so as to align the back surface of the workpiece with the manipulator, enabling the manipulator to directly grasp the workpiece onto the frame of the fixture, reducing the force on the connection between the pressure plate and the buckle, reducing the separation between the pressure plate and the buckle, and increasing the welding stability;

[0033] 3. Using an electric telescopic rod or a hydraulic telescopic rod facilitates the electric control of the first telescopic rod and the second telescopic rod, and increases the automation degree of the welding device. Description of the Drawings

[0046] The following further describes the present application in detail in conjunction with the appended Figure 1 - appended Figure 3 , and makes a further detailed description of the present application.

[0047] The automatic welding device provided by the embodiment of the present application, as Figure 1 shown, includes a welding table 1, a receiving table 2, a manipulator 3, a first conveyor belt 4, a second conveyor belt 5, and a moving mechanism 6. The welding table 1 is used for welding the workpiece 9; the receiving table 2 corresponds to the position of the welding table 1 and is used for temporarily storing the workpiece 9 conveyed from the first conveyor belt 4; the manipulator 3 corresponds to the position of the receiving table 2 and is used for clamping and moving the workpiece 9 from the receiving table 2 to the position of the welding table 1 for welding; the first conveyor belt 4 is used for conveying the workpiece 9 to be welded to the receiving table 2; the second conveyor belt 5 is used for transporting the welded workpiece 9 away from the receiving table 2; the moving mechanism 6 is used for moving the workpiece 9 on the receiving table 2 to the second conveyor belt 5 after welding is completed for transportation away.

[0048] Specifically, the workpiece 9 is composed of a fixture and two stacked automotive parts. The fixture fixes the two stacked automotive parts to each other to form the workpiece 9 to be welded.

[0049] Specifically, the soldering table 1 is composed of a mounting base 11 and two soldering heads 12. The two soldering heads 12 are symmetrically arranged up and down and there is a gap between the two soldering heads 12. After the manipulator 3 grips the workpiece 9, the part of the workpiece 9 that needs to be soldered is inserted into the gap, so that the two soldering heads 12 solder the workpiece 9. After soldering one part, through the rotation, translation and other actions of the manipulator 3, the next part of the workpiece 9 that needs to be soldered is moved to the gap for soldering.

[0050] Specifically, the moving mechanism 6 includes a slide plate 61 and a driving component 62. The slide plate 61 is slidably connected to the receiving table 2 and is located between the first conveyor belt 4 and the second conveyor belt 5. The driving component 62 is used to provide power to drive the slide plate 61 to reciprocally slide between the first conveyor belt 4 and the second conveyor belt 5, thereby realizing the movement of the workpiece 9.

[0051] Refer to Figure 2 and Figure 3 , the receiving table 2 is provided with a first guide rail 21 and a second guide rail 22. The first guide rail 21 and the second guide rail 22 are symmetrically arranged. The two sides of the slide plate 61 are respectively slidably connected to the first guide rail 21 and the second guide rail 22. Specifically, grooves 23 are formed on the mutually approaching surfaces of the first guide rail 21 and the second guide rail 22. The two sides of the slide plate 61 are respectively inserted into the corresponding grooves 23 to realize the sliding connection of the slide plate 61. The size of the slide plate 61 is smaller than that of the workpiece 9. The end of the groove 23 close to the first conveyor belt 4 is the loading end, and the end of the groove 23 close to the second conveyor belt 5 is the unloading end;

[0052] In the initial stage, the slide plate 61 is located at the loading end. The first conveyor belt 4 operates to transport the workpiece 9 onto the slide plate 61. At this time, the manipulator 3 grabs the workpiece 9 for soldering. The soldered workpiece 9 is placed on the slide plate 61 again. At this time, the end of the workpiece 9 far from the first conveyor belt 4 is suspended. The driving component 62 drives the slide plate 61 to move, so that the slide plate 61 moves in the direction close to the unloading end, so that the workpiece 9 contacts the second conveyor belt 5 and slowly moves onto the second conveyor belt 5. At this time, the second conveyor belt 5 operates to drive the workpiece 9 to move, so that the workpiece 9 is separated from the slide plate 61, and then the driving component 62 drives the slide plate 61 to reset, and the next loading can be carried out.

[0053] The driving component 62 includes a first telescopic rod 621 and an elastic member 622. A mounting plate 8 is fixedly connected to the frame on the first conveyor belt 4. One end of the first telescopic rod 621 is fixedly connected to the mounting plate 8, and the other end can abut against the slide plate 61 and push the slide plate 61 to move. Specifically, a push plate 611 is fixedly connected to the end of the slide plate 61 close to the first conveyor belt 4. The end of the first telescopic rod 621 far from the mounting plate 8 abuts against the push plate 611. Through the expansion and contraction of the first telescopic rod 621, the push plate 611 is driven to move, thereby realizing the sliding of the slide plate 61.

[0054] One of the above elastic members 622 is provided in each chute 23. One end of the elastic member 622 is fixedly connected to the sliding plate 61, and the other end is fixedly connected to the blanking end of the first guide rail 21 or the second guide rail 22. That is, the elastic member 622 is connected to the receiving table 2 and is used to provide a certain buffering and reset function during the movement of the sliding plate 61.

[0055] The first telescopic rod 621 can be an electric telescopic rod or a hydraulic telescopic rod, and the sliding plate 61 is pushed to slide on the receiving table 2 through telescopic movement. The elastic member 622 can be an elastic element such as a spring, which is used to provide a certain buffering effect when the sliding plate 61 is subjected to a thrust or a pull force, preventing excessive impact force from being generated between the sliding plate 61 and the receiving table 2. And when the first telescopic rod 621 resets, the elastic member 622 can drive the sliding plate 61 to automatically reset.

[0056] Furthermore, a second telescopic rod 7 is also provided on the receiving table 2. One end of the second telescopic rod 7 is hinged to the receiving table 2, and the other end is hinged to the second guide rail 22. By the telescopic movement of the second telescopic rod 7, the second guide rail 22 can be driven to move, so as to realize the rotation of the sliding plate 61.

[0057] The fixture consists of a frame body, a pressing plate and a locking buckle. The pressing plate is rotatably connected to the frame body, and the locking buckle is fixed on the frame body and is used to fix the pressing plate. Since the fixture presses two automotive parts through the pressing plate and then locks the pressing plate through the locking buckle, when using the clamping jaw to directly clamp the workpiece 9, it will directly clamp on the pressing plate on the top surface. During the process of the manipulator 3 driving the workpiece 9 to move, because it is directly clamped on the pressing plate, the force on the workpiece 9 will be transmitted to the connection between the pressing plate and the locking buckle, which is likely to cause the pressing plate and the locking buckle to disengage from each other;

[0058] By driving the second guide rail 22 to rotate through the second telescopic rod 7, the sliding plate 61 is rotated, so that the back surface of the workpiece 9 is aligned with the manipulator 3, enabling the manipulator 3 to directly grasp the frame body of the fixture, reducing the force on the connection between the pressing plate and the locking buckle, reducing the separation of the pressing plate and the locking buckle, and increasing the welding stability.

[0059] Specifically, two second telescopic rods 7 can be provided, and they are located on the side of the sliding plate 61 away from the welding table 1 and are distributed at both ends of the sliding plate 61. This can provide more stable and reliable rotational power. At the same time, the second telescopic rod 7 can also be an electric telescopic rod or a hydraulic telescopic rod and other elements with telescopic functions.

[0060] The implementation principle of this embodiment is as follows: Through the automated welding device, the automatic feeding, temporary storage, clamping, welding and removal of the workpiece 9 are realized, greatly improving the production efficiency and welding quality. At the same time, through the design of the moving mechanism 6, the workpiece 9 can automatically move onto the second conveyor belt 5 after welding, further improving the automation degree of the device.

[0061] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same parts are denoted by the same reference numerals. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
