The left and right movement of the pusher block 16 can drive the second rotating rod 23 to rotate around the second rotating seat 22 through the first rotating seat 20 and the first rotating rod 21.

[0023] The track frame 3 is provided with two sets of first opening slots 4, and the pusher block 16 is provided with two sets of second opening slots 29, and the first opening slots 4, the second opening slots 29, and the first rotating rod 21 are adapted to each other (by Figure 4 and Figure 6 and Fig. 9 The first opening slot 4 and the second opening slot 29 facilitate the rotation of the first rotating rod 21 to avoid interference.

[0024] The unloading mechanism 31 includes two groups of extension frames 9, and the two groups of extension frames 9 are fixedly connected to the track frame 3. One end of the two groups of extension frames 9 is fixedly connected to the end baffle 11. A platform with an inclined surface 18 is provided between the two groups of extension frames 9. A step is provided on the platform with an inclined surface 18. The side of the platform with an inclined surface 18 close to the track frame 3 is an inclined surface. The lower end of the platform with an inclined surface 18 is fixedly connected to a fixed connecting rod 25. The lower end of the fixed connecting rod 25 is fixedly connected to a fixed plate 27. The upper end of the fixed plate 27 is fixedly connected to a second spring 26. The second spring The upper end of 26 is fixedly connected with the L-shaped slide plate 12, and the fixed connecting rod 25 is connected with the L-shaped slide plate 12 through and through, the track frame 3 is provided with a track groove 28, and the L-shaped slide plate 12 is connected with the track groove 28 by sliding buckle, and one side of the L-shaped slide plate 12 is fixedly connected with the first spring 13, and the first spring 13 is fixedly connected with the inner wall of the track frame 3; the push block 16 moves rightward, which will push the L-shaped slide plate 12 to compress the first spring 13, and the L-shaped slide plate 12 drives the fixed connecting rod 25 to move rightward, and the inclined platform 18 moves downward under the action of its upper inclined surface ( Figure 5The right side of the middle inclined surface platform 18 is provided with an inclined surface. As the L-shaped slide plate 12 moves to the right, the inclined surface of the inclined surface platform 18 contacts the lower surface of the track frame 3, causing the inclined surface platform 18 to move downward. The second spring 26 is stretched, and the inclined surface platform 18 is separated from between the two groups of extension frames 9. The inclined surface platform 18 continues to move to the right and separates from the two groups of extension frames 9. The combination of the first workpiece 7 and the second workpiece 8 on the inclined surface platform 18 will fall down ( Figure 5 The right side of the middle inclined surface platform 18 is provided with an inclined surface. When the inclined surface of the inclined surface platform 18 contacts the lower surface of the track frame 3, the inclined surface platform 18 moves downward. As the L-shaped slide plate 12 moves rightward, the inclined surface platform 18 continues to move rightward. The inclined surface platform 18 will completely leave from under the extension frame 9. At this time, the combination of the first workpiece 7 and the second workpiece 8 will fall down.).

[0025] Two groups of limiting strips 24 are fixedly connected to the upper end of the inner wall of the track frame 3, a blanking limiting groove 19 is set on one side of the pushing block 16, and the spacing between the two groups of limiting strips 24 is equal to the width of the blanking limiting groove 19, and two groups of second supporting legs 5 are fixedly connected to the upper end of the base plate 1, and a blanking frame 6 is fixedly connected between the two groups of second supporting legs 5, and the blanking frame 6 is adapted to the blanking limiting groove 19, and multiple groups of first workpieces 7 are arranged in the blanking frame 6, and the sum of the height of the blanking limiting groove 19 and the depth of the two groups of limiting strips 24 is exactly equal to the height of a group of first workpieces 7 (to ensure that each time the pushing block 16 passes under the blanking frame 6, only one group of first workpieces 7 can be pushed), when the blanking limiting groove 19 passes directly under the blanking frame 6, a group of first workpieces 7 will fall between the two groups of limiting strips 24, and the width of the blanking limiting groove 19 is equal to that of the first workpiece 7.

[0026] An arc-shaped notch groove 17 is arranged on each group of extension frames 9, and the arc-shaped notch groove 17 is located on the movement trajectory of the welding gun 10. A cleaning brush 32 is arranged on one side of each group of arc-shaped notch grooves 17; when the welding gun 10 passes through the cleaning brush 32, the cleaning brush 32 can clean the muzzle of the welding gun 10; a second workpiece 8 is placed on the upper end of the inclined platform 18.

[0027] The device is used for welding low-density high-strength steel test blocks. The device is placed on the workbench ( Figure 8 )superior.

[0028] In the specific operation, the robot first places the second workpiece 8 on the inclined platform 18, and adds multiple groups of first workpieces 7 into the blanking frame 6. Figure 1The state shown is the initial state and the basic view. At this time, the blanking limit groove 19 moves just below the blanking frame 6. A group of first workpieces 7 in the blanking frame 6 passes through the blanking limit groove 19 and falls between the two groups of limit strips 24. The cylinder 15 controls the telescopic rod 14 to extend, driving the push block 16 to move left. The push block 16 pushes the first workpiece 7 that falls between the two groups of limit strips 24 to move left and combine with the second workpiece 8. The first workpiece 7 and the second workpiece 8 are interference fit. The push block 16 provides pressure to combine the first workpiece 7 and the second workpiece 8. When the push block 16 moves left, it will also drive the second rotating rod 23 around the second rotating seat through the first rotating rod 21. 22 rotates clockwise, and after the first workpiece 7 and the second workpiece 8 are assembled, the cylinder 15 moves in the opposite direction, and the pusher block 16 moves to the right. During this process, the pusher block 16 drives the second turn bar 23 to rotate counterclockwise through the first turn bar 21, and the welding gun 10 can weld the gaps on the front and back sides of the first workpiece 7 and the second workpiece 8 (the upper and lower sides of the first workpiece 7 and the second workpiece 8 have a matching relationship with other parts, and welding is not performed to prevent the weld from affecting the matching). After the welding is completed, the welding gun 10 stops immediately, and when the welding gun 10 passes through the cleaning brush 32, the cleaning brush 32 can clean the muzzle of the welding gun 10 to clean up the welding slag at the muzzle of the welding gun 10, and then moves to Figure 1 In the state shown, a group of first workpieces 7 passes through the blanking limit groove 19 and falls between the two groups of limit strips 24. At the same time, the pusher block 16 contacts the L-shaped slide plate 12. The pusher block 16 continues to move right, which will push the L-shaped slide plate 12 to compress the first spring 13. The L-shaped slide plate 12 drives the fixed connecting rod 25 to move right. The inclined platform 18 moves downward under the action of its upper inclined surface. The second spring 26 is stretched, and the inclined platform 18 is separated from between the two groups of extension frames 9. The inclined platform 18 continues to move right and separates from the two groups of extension frames 9. The combination of the two groups of first workpieces 7 and the second workpiece 8 on the inclined platform 18 will fall down ( Figure 5 The right side of the middle inclined surface platform 18 is provided with an inclined surface. When the inclined surface of the inclined surface platform 18 contacts the lower surface of the track frame 3, the inclined surface platform 18 moves downward. As the L-shaped slide plate 12 moves rightward, the inclined surface platform 18 continues to move rightward. The inclined surface platform 18 completely leaves from under the extension frame 9. At this time, the first workpiece 7 and the second workpiece 8 combination will leak out. (If the first workpiece 7 and the second workpiece 8 combination does not leak out from directly under the two sets of extension frames 9, it means that the welding deformation does not meet the welding quality requirements, and the welded product is defective, thereby achieving the purpose of welding deformation inspection). Then the cylinder 15 starts forward to control the extension of the telescopic rod 14 and return to Figure 1 In the initial state shown, the inclined platform 18 returns to between the two groups of extension frames 9 again, and the robot places a new second workpiece 8 on the inclined platform 18 .

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
