Description

Technical Field

[0001] This utility model relates to the field of fertilizer palletizing technology, specifically to a robotic arm structure for grasping and palletizing fertilizer stacks. Background Technology

[0002] A palletizer is an automated industrial device primarily used to neatly stack products (such as boxes, barrels, and bagged materials) according to preset rules (such as row and column arrangement, number of layers, and height). It is widely used in logistics, warehousing, and manufacturing. In the workshop, bagged fertilizer is conveyed to the palletizer via a conveyor belt and then stacked onto pallets.

[0003] After prolonged use, the fasteners connecting the palletizer to the robotic arm become subjected to constant stress, which can lead to breakage or loosening, causing the palletizer to fall and potentially causing a safety accident. Therefore, a robotic arm structure for grasping and stacking fertilizer stacks is needed to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to provide a robotic arm gripping and stacking structure for fertilizer stacks, thereby solving the problems mentioned in the background section. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a robotic arm structure for grasping and stacking fertilizer piles, comprising:

[0006] A column-type palletizer includes a base, a column, a support block, a first robotic arm, and a second robotic arm. The lower end of the column is rotatably connected to the middle of the upper end of the base, the support block is slidably connected to the side of the column, one end of the first robotic arm is fixed to the other side of the support block away from the column, and one end of the second robotic arm is rotatably connected to the lower part of the other end of the first robotic arm away from the support block.

[0007] A fall arrestor assembly includes a support column, a first support rod, a second support rod, a third support rod, a first through hole, a limiting post, a limiting plate, a fourth support rod, and a second through hole. One end of the support column is fixed to the top of the column, one end of the first support rod is fixed to the upper end of the support column, the second support rod is fixed to the lower end of the first support rod, the third support rod is fixed to the lower end of the second support rod, the first through hole is opened at both ends of the third support rod, the fourth support rod is fixed to both sides of the end of the first robotic arm near the second robotic arm, the second through hole is opened on the fourth support rod, the limiting post is inserted into the first through hole and the second through hole, and is fastened at the first through hole by a nut, and the limiting plate is fixed to the lower end of the limiting post.

[0008] Furthermore, the fall arrestor also includes a movable hole and a screw. The movable hole is located in the middle of the first support rod, and the screw is fixed to the upper end of the second support rod and inserted into the movable hole, and is fastened by a nut.

[0009] Furthermore, the fall arrestor also includes a clamp, which is wrapped around the end of the first robotic arm near the second robotic arm, and a fourth support rod is fixed to both ends of the clamp.

[0010] Furthermore, the column is equipped with a bellows-shaped protective cover on its side and is located on both sides of the support block, and the end of the second robotic arm away from the first robotic arm is equipped with a claw gripper.

[0011] Furthermore, it also includes a damage prevention component, which includes an L-shaped support rod and a support plate. One end of the L-shaped support rod is fixed to the lower end of the clamp, one end of the support plate is fixed to the lower end of the L-shaped support rod, and the other end is located at the lower end of the second robotic arm.

[0012] Furthermore, the damage prevention component also includes a mounting hole and a reinforcing plate. The mounting hole is opened at one end of the L-shaped support rod and is fixed to the clamp by screws. The reinforcing plate is fixed to the L-shaped support rod and the support plate.

[0013] Furthermore, the damage prevention component also includes ball bearings that are rotatably connected to the support plate and attached to the lower end of the second robotic arm.

[0014] This utility model has the following beneficial effects:

[0015] This invention, through the inclusion of a fall-prevention component, installs a clamp on the end of the first robotic arm near the second robotic arm without affecting the normal rotation of the second robotic arm. The second support rod under the first support rod moves along the movable hole to the position corresponding to the clamp, and the nut on the screw is tightened. The limiting post passes through the second through hole of the fourth support rod until it passes through the first through hole of the third support rod. The nuts at both ends of the third support rod are tightened, placing the limiting plate at the bottom of the vertical movement of the first robotic arm. When the palletizer is in use, as the support block moves the first robotic arm up and down, it moves the fourth support rod along the limiting post. If the fastener at the connection between the first robotic arm and the support block breaks and falls, it will fall downwards along the limiting post. However, due to the limiting plate, it will not fall to the ground. This design prevents the first robotic arm from falling directly to the ground, reducing the degree of damage to the first robotic arm. Attached Figure Description

[0027] Please see Figure 1-5 As shown, this utility model is a robotic arm gripping and stacking structure for fertilizer stacks, comprising:

[0028] The column palletizer includes a base 10, a column 11, a support block 12, a first robotic arm 13, and a second robotic arm 14. The lower end of the column 11 is rotatably connected to the middle of the upper end of the base 10. The support block 12 is slidably connected to the side of the column 11. One end of the first robotic arm 13 is fixed to the other side of the support block 12 away from the column 11. One end of the second robotic arm 14 is rotatably connected to the lower part of the other end of the first robotic arm 13 away from the support block 12.

[0029] The column 11 is equipped with a bellows protective cover on its side and is located on both sides of the support block 12. The second robotic arm 14 is equipped with a claw gripper at the end away from the first robotic arm 13.

[0030] The base 10 and the column 11 provide support. The base 10 is equipped with a motor that can control the rotation of the column 11. The support block 12 serves as a connector and can move up and down along the column 11. The motor and belt drive the support block 12 to move up and down. The first robotic arm 13 and the second robotic arm 14 facilitate the movement of the fertilizer bag.

[0031] The fall arrestor assembly includes a support column 20, a first support rod 21, a second support rod 24, a third support rod 25, a first through hole 250, a limiting post 26, a limiting plate 260, a fourth support rod 28, and a second through hole 280. One end of the support column 20 is fixed to the top of the column 11. One end of the first support rod 21 is fixed to the upper end of the support column 20. The second support rod 24 is fixed to the lower end of the first support rod 21. The third support rod 25 is fixed to the lower end of the second support rod 24. The first through hole 250 is opened at both ends of the third support rod 25. The fourth support rod 28 is fixed on both sides of the end of the first robotic arm 13 near the second robotic arm 14. The second through hole 280 is opened on the fourth support rod 28. The limiting post 26 is inserted into the first through hole 250 and the second through hole 280, and is fastened at the first through hole 250 by a nut. The limiting plate 260 is fixed to the lower end of the limiting post 26.

[0032] The fall arrestor also includes a movable hole 22 and a screw 23. The movable hole 22 is opened in the middle of the first support rod 21, and the screw 23 is fixed to the upper end of the second support rod 24 and inserted into the movable hole 22 and fastened by a nut.

[0033] The fall arrestor also includes a clamp 27, which is wrapped around one end of the first robotic arm 13 near the second robotic arm 14, and a fourth support rod 28 is fixed to both ends of the clamp 27.

[0034] Support column 20 provides support, first support rod 21 provides support, movable hole 22 facilitates adjustment of the position of second support rod 24, screw 23 is used to fasten second support rod 24, second support rod 24 and third support rod 25 provide support, first through hole 250 is used to connect limiting column 26, limiting column 26 provides limiting, limiting plate 260 provides support, clamp 27 provides connection, fourth support rod 28 provides connection, second through hole 280 facilitates connection of limiting column 26.

[0035] Working principle:

[0036] Install clamp 27 on the end of the first robotic arm 13 near the second robotic arm 14 without affecting the normal rotation of the second robotic arm 14. Move the second support rod 24 under the first support rod 21 along the movable hole 22 to the position corresponding to clamp 27. Tighten the nut on screw 23. The limiting post 26 passes through the second through hole 280 of the fourth support rod 28 until it passes through the first through hole 250 of the third support rod 25. Tighten the nuts at both ends of the third support rod 25 so that the limiting plate 260 is located at the bottom of the vertical movement of the first robotic arm 13. When the palletizer is in use, when the support block 12 drives the first robotic arm 13 to move up and down, it drives the fourth support rod 28 to move along the limiting post 26. If the fastener at the connection between the first robotic arm 13 and the support block 12 breaks and falls, it will fall down along the limiting post 26. It will not fall to the ground due to the limiting plate 260.

[0037] This step can prevent the first robotic arm 13 from falling directly to the ground and reduce the degree of damage to the first robotic arm 13.

[0038] Please see Figure 6 As shown, this embodiment, based on the above embodiment, further includes:

[0039] The damage prevention component includes an L-shaped support rod 30 and a support plate 33. One end of the L-shaped support rod 30 is fixed to the lower end of the clamp 27, and one end of the support plate 33 is fixed to the lower end of the L-shaped support rod 30, while the other end is located at the lower end of the second robotic arm 14.

[0040] The damage prevention component also includes a mounting hole 31 and a reinforcing plate 32. The mounting hole 31 is opened at one end of the L-shaped support rod 30 and is fixed to the clamp 27 by screws. The reinforcing plate 32 is fixed to the L-shaped support rod 30 and the support plate 33.

[0041] The damage prevention component also includes a ball bearing 34, which is rotatably connected to the support plate 33 and fits against the lower end of the second robotic arm 14.

[0042] The L-shaped support rod 30 and support plate 33 provide support, the mounting hole 31 facilitates fixing the L-shaped support rod 30, the reinforcing plate 32 provides reinforcement, and the ball bearing 34 provides support and can reduce the frictional resistance when the second robotic arm 14 rotates.

[0043] Working principle:

[0044] After installing the anti-fall components, fit the mounting hole 31 of the L-shaped support rod 30 onto the bolt at the lower end of the clamp 27 and tighten the nut so that the ball bearings 34 on the support plate 33 fit against the lower end of the second robotic arm 14. When the palletizer is in use, the second robotic arm 14 rotates, causing the ball bearings 34 to roll.

[0045] This step can provide support at the connection between the first robotic arm 13 and the second robotic arm 14, reducing the damage to the bearing at the connection between the first robotic arm 13 and the second robotic arm 14 under the influence of gravity during long-term use of the palletizer.
