Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an automatic stacking device for large-volume space frame bolts includes a processing table 4 and a vibrating feeder 1 for feeding bolts. The top of the processing table 4 and the top of the conveying channel 2 are fixedly connected to the conveying channel 2.

[0027] Two sets of movable seats 11 and movable seats 22 are fixedly installed on both sides of the mounting slot 5. A mounting seat 9 is provided on one side of each set of movable seats 11 and movable seats 22. A mounting cylinder 13 is fixedly installed inside one set of mounting seats 9, and an abutment 10 is fixedly installed inside the other set of mounting seats 9. The mounting seats 9 are fixedly installed on the processing table 4. A sensor 28 is provided on the outside of each set of movable seats 11 and movable seats 22.

[0028] A movable plate 8 is fixedly installed at the bottom of the processing table 4. A drive device 16 is provided on one side of the movable plate 8. The drive device 16 is electrically connected to the sensor 28. The drive device 16 includes a collection block 14 and an adjustable block 15 that pass through the inside of the mounting groove 5. The drive device 16 is used to drive the collection block 14 and the adjustable block 15 to feed materials into the movable seat 11 and the movable seat 2 12.

[0029] In this embodiment, the vibratory feeder 1 feeds the bolts into the conveying channel 2. The conveyor 3 drives the bolts to be transported until the end of the conveying channel 2. Due to the restriction of the limiting member 7, the bolts fall into the adjustable block 15. The drive device 16 drives the collecting block 14 to move. The next set of bolts falls into the collecting block 14. The drive device 16 then drives the collecting block 14 and the adjustable block 15 to feed the bolts into the moving seat 11 and the moving seat 2 12.

[0030] The distance between the two sets of bolts is measured by sensor 28. If the distance is the same, the two sets of bolts are adjusted again by drive device 16 so that they fall back into movable seat 11 and movable seat 12 after adjustment, so as to achieve the purpose of stacking the bolts in opposite directions before welding.

[0031] As one implementation method, such as Figure 1 , Figure 3 and Figure 4 As shown, the drive device 16 also includes a guide rail 22 and a transverse cylinder 20 fixedly installed on one side of the movable plate 8. A slide block 19 is slidably installed on the guide rail 22. The output end of the transverse cylinder 20 is fixedly connected to the slide block 19. A vertical cylinder 21 is fixedly installed on one side of the slide block 19. A fixed plate 18 is fixedly installed on the output end of the vertical cylinder 21. An adjustable locking block 15 is located on the fixed plate 18.

[0032] A rotating component 17 is fixedly installed on the top of the fixed plate 18. The rotating component 17, the transverse cylinder 20 and one of the sensor groups 28 are electrically connected. The output end of the rotating component 17 is fixedly connected to the collection block 14.

[0033] Two sets of guide rods 23 are fixedly installed at the bottom of the fixed plate 18, and the guide rods 23 are slidably installed inside the slide block 19.

[0034] In this embodiment, bolts are placed on the adjustable locking block 15 and the collecting locking block 14. The vertical cylinder 21 drives the fixed plate 18 to move upward. The adjustable locking block 15 and the collecting locking block 14 on the fixed plate 18 move upward. Then, the horizontal cylinder 20 drives the slide block 19 to move to one side until the positions of the adjustable locking block 15 and the collecting locking block 14 correspond to the moving seat 11 and the moving seat 22. Then, the vertical cylinder 21 drives the fixed plate 18 to descend. The two sets of bolts fall into the slots 29 in the moving seat 11 and the moving seat 22 respectively. Then, the output end of the mounting cylinder 13 extends and moves the two sets of bolts respectively until they abut against the limiting member 7.

[0035] The distance between the two sets of bolts is measured by sensor 28. If the distances are the same, the vertical cylinder 21 drives the fixed plate 18 to move upward. The adjustable block 15 and the collecting block 14 on the fixed plate 18 move upward. At the same time, the rotating part 17 drives the adjustable block 15 to rotate 180 degrees. Finally, the vertical cylinder 21 moves downward, and the two sets of bolts fall back into the moving seat 11 and the moving seat 22, completing the opposite stacking.

[0036] As one implementation method, such as Figure 1 , Figure 2 As shown, the top of the movable base 11 and the movable base 22 are provided with slots 29 for bolt engagement, and the slots 29 have a V-shaped opening.

[0037] The collecting card block 14 and the adjustable card block 15 are arranged in parallel to each other. The top of the collecting card block 14 and the adjustable card block 15 are provided with V-shaped grooves, and the collecting card block 14 and the adjustable card block 15 correspond to the first movable seat 11 and the second movable seat 12, respectively.

[0038] In this embodiment, the adjustable locking block 15 on the fixed plate 18 and the V-shaped groove on the collecting locking block 14 are used to collect the bolts. After collection, the driving device 16 feeds the bolts on the adjustable locking block 15 and the collecting locking block 14 to the moving seat 11 and the moving seat 2 12 for stacking.

[0039] As one implementation method, such as Figure 3 As shown, the limiting component 7 includes a limiting plate 25 fixedly installed on the processing table 4, and a limiting head 26 fixedly installed on the top of the limiting plate 25.

[0040] In this embodiment, the vibrating feeder 1 feeds bolts into the conveying channel 2, and the conveyor 3 drives the bolts to be transported until the end of the conveying channel 2. The bolts then contact the limiting head 26, causing the bolts to fall into the adjustable locking block 15. The drive device 16 moves the bolts, and the next set of bolts falls into the collecting block 14.

[0041] As one implementation method, such as Figure 3As shown, the processing table 4 has multiple sets of elongated holes 6 inside. The limiting plate 25, the second movable seat 12, the first movable seat 11, the mounting seat 9 and the elongated holes 6 are connected by fastening bolts.

[0042] In this embodiment, the elongated hole 6 is used to connect with the fastening bolt, thereby adjusting the position of the limiting plate 25, the second movable seat 12, the first movable seat 11, and the mounting seat 9 to accommodate bolts of other sizes.

[0043] Working principle: When in use, a large number of bolts are placed in the vibrating feeder 1. The vibrating feeder 1 vibrates and feeds the bolts into the conveying channel 2. The conveyor 3 drives the bolts to be transported until the end of the conveying channel 2. Due to the restriction of the limiting part 7, the bolts first fall into the adjustable block 15. The horizontal cylinder 20 drives the slide 19 to move, and the next group of bolts falls into the collecting block 14.

[0044] At this point, the vertical cylinder 21 drives the fixed plate 18 to move upward, and the adjustable locking block 15 and the collecting locking block 14 on the fixed plate 18 move upward. Then, the horizontal cylinder 20 drives the slide block 19 to move to one side until the positions of the adjustable locking block 15 and the collecting locking block 14 correspond to the positions of the moving seat 11 and the moving seat 22. At this time, the vertical cylinder 21 drives the fixed plate 18 to descend, and the two sets of bolts fall into the slots 29 in the moving seat 11 and the moving seat 22, respectively. Then, the output end of the mounting cylinder 13 extends to move the two sets of bolts. Until the contact joint 10 is reached, the distance between the two sets of bolts is measured by the sensor 28. If the distance is the same, the vertical cylinder 21 drives the fixed plate 18 to move upward. The adjustable block 15 and the collecting block 14 on the fixed plate 18 move upward. At the same time, the rotating part 17 drives the adjustable block 15 to rotate 180 degrees. Finally, the vertical cylinder 21 moves downward, and the two sets of bolts fall into the moving seat 11 and the moving seat 2 12 again. Finally, the robot accurately grabs the bolts with opposite directions and places them into the end of the steel pipe workpiece before welding.
