Description

Technical Field

[0001] The present invention relates to the technical field, and in particular to a mechanical automated grasping device. Background Art

[0002] In the industrial production process, mechanical automatic grasping devices are needed to automatically shift objects. Mechanical automatic grasping devices are the earliest industrial robots and also the earliest modern robots. They can replace people's heavy labor to realize the mechanization and automation of production. They can operate in harmful environments to protect personal safety. Therefore, they are widely used in machinery manufacturing, metallurgy, electronics, light industry and atomic energy.

[0003] Due to high temperatures in summer, fresh food markets, chemical transport, and factory workshops require large quantities of ice for physical cooling and food preservation. Currently, in ice factories, ice produced on the production line is first transported to the factory's cold storage room for storage, awaiting subsequent shipment based on orders. Uncut ice is bulky and has a smooth surface, so a gripping device is often required during its transportation.

[0004] During storage, ice cubes are large and have smooth surfaces, making them prone to misalignment. If a gripping device were used to directly grasp multiple misaligned ice cubes, the misaligned arrangement could easily lead to unstable gripping, which could cause ice cubes to fall during movement. Therefore, manual alignment of the multiple ice cubes before grasping is required, resulting in low efficiency. Therefore, this application proposes a mechanically automated gripping device to address the aforementioned issues. Summary of the Invention

[0005] The present invention provides a mechanical automated grasping device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A mechanical automated grabbing device includes a grabbing shell with an opening at the bottom. The interior of the grabbing shell is movably connected with a vertical clamping plate and a horizontal clamping plate. The vertical clamping plate and the horizontal clamping plate can be moved to regularly arrange and clamp ice cubes placed in the grabbing shell, thereby facilitating subsequent grabbing.

[0008] A plurality of connecting blocks are fixedly connected to the outer surface of the grab shell, each of the connecting blocks is movably connected to a sliding column, the bottom end of the sliding column is movably connected to a base, the top end of the sliding column is movably connected to a top frame, and the bottom of the base is fixedly connected to a pulley.

[0009] A further improvement of the technical solution of the present invention is that the two sliding posts are threadedly connected to the connecting block, and matching threads are provided at the connection between the outer surface of the sliding post and the connecting block.

[0010] A further improvement of the technical solution of the present invention is that a transverse sliding groove is provided on the top of the grab shell, and the transverse clamping plate slides transversely along the transverse sliding groove through a transverse sliding block.

[0011] A plurality of vertical sliding grooves are provided on the top of the grabbing shell, and the vertical clamping plate slides vertically along the vertical sliding grooves through a plurality of vertical sliding blocks.

[0012] A further improvement of the technical solution of the present invention is that when the vertical clamping plate slides along the vertical sliding groove to a minimum distance from the horizontal clamping plate, the distance is greater than the width of the horizontal clamping plate.

[0013] A further improvement of the technical solution of the present invention is that the bottom of the grab shell is movably connected to two baffles, which can be completely separated by moving back to back to completely expose the bottom of the grab shell, and the two baffles move towards each other to close the bottom of the grab shell.

[0014] A further improvement of the technical solution of the present invention is that: each baffle is movably connected with a connecting rod, one end of the connecting rod is movably connected to the driving slider, the driving slider is threaded with an outer column, the inner wall of the outer column is movably connected with a limiting sliding column, the top end of the limiting sliding column is movably connected to the top frame, and the bottom end of the limiting sliding column is movably connected to the base through the bottom plate.

[0015] A further improvement of the technical solution of the present invention is that one end of the outer column is fixedly connected to a limiting ring.

[0016] A further improvement of the technical solution of the present invention is that: one end of the sliding column threadedly connected to the connecting block extending to the outside of the top frame is fixedly connected to the driving wheel, and the one end of the limiting sliding column extending to the outside of the top frame is fixedly connected to the driven wheel, and the driven wheel and the driving wheel are engaged and connected by a drive chain.

[0017] A further improvement of the technical solution of the present invention is that the number of gear teeth of the driven wheel is smaller than the number of gear teeth of the driving wheel.

[0018] Due to the adoption of the above technical solution, the present invention has the following technical advancements compared to the prior art:

[0019] The ice cubes are then lifted up to a suitable position by the action of a base and a pulley, and the ice cubes are then moved down, and the vertical and horizontal clamping plates are moved in opposite directions. Finally, the ice cubes are lifted up to a certain height, and the ice cubes are grabbed to a suitable position, thereby avoiding the situation that the ice cubes are not arranged properly and the clamping is unstable. It also avoids the need for manual arrangement of the ice cubes to be grabbed before the grabbing operation is performed, which leads to low efficiency.

[0020] 2. The present invention provides a mechanical automated grabbing device. When the grabbing shell is at the lowest point and ice cubes are being grabbed, the two baffles are completely separated and the bottom of the grabbing shell is completely exposed. When the ice cubes are grabbed inside the grabbing shell and the grabbing shell needs to be lifted, the two baffles move toward each other to close the bottom of the grabbing shell, thereby supporting the ice cubes inside the grabbing shell and reducing the possibility of the ice cubes falling.

DETAILED DESCRIPTION

[0028] The present invention is described in further detail below in conjunction with the embodiments:

[0029] Example:

[0030] like Figure 1-6 As shown, the present invention provides a mechanical automated grasping device, including a grasping shell 1, the bottom of which is open, and the interior of the grasping shell 1 is movably connected with a vertical splint 4 and a horizontal splint 7. By moving the vertical splint 4 and the horizontal splint 7, the ice cubes placed in the grasping shell 1 can be regularly arranged and clamped, which is convenient for subsequent grasping.

[0031] A plurality of connecting blocks 8 are fixedly connected to the outer surface of the grab shell 1, and each connecting block 8 is movably connected to a sliding column 11, the bottom end of the sliding column 11 is movably connected to the base 9, the top end of the sliding column 11 is movably connected to the top frame 12, and the bottom of the base 9 is fixedly connected to a pulley 10.

[0032] The grabbing shell 1 is used to cover multiple uneven ice cubes to be grabbed inside, and then the vertical clamping plate 4 is slowly moved vertically, and then the horizontal clamping plate 7 is slowly moved horizontally, until all the ice cubes are pushed and regularized in two directions, and are arranged neatly, and the multiple ice cubes covered by the grabbing shell 1 are clamped tightly by the movement of the vertical clamping plate 4 and the horizontal clamping plate 7. Then, the grabbing shell 1 and the ice cubes are driven to rise to a certain height together by the sliding column 11 through the connecting block 8. Then, the ice cubes are moved to a suitable position through the action of the base 9 and the pulley 10, and the grabbing shell 1 is put down, and the vertical clamping plate 4 and the horizontal clamping plate 7 are moved in the opposite direction. Finally, the grabbing shell 1 is lifted to a certain height, and the ice cubes can be grabbed to a suitable position, thereby avoiding the situation that the ice cubes are not neatly arranged and the clamping is unstable, and also avoiding the need to manually arrange the multiple ice cubes to be clamped and then perform the grabbing operation, which leads to low efficiency.

[0033] Furthermore, the two sliding posts 11 are threadedly connected to the connecting block 8, and matching threads are provided at the connection between the outer surface of the sliding post 11 and the connecting block 8. A driving device 24 is fixedly connected to the top frame 12. The driving device 24 is a prior art, and the output shaft of the driving device 24 is fixedly connected to the sliding post 11. The sliding post 11 can be driven to rotate by the driving device 24. When the sliding post 11 rotates, the grab shell 1 can be driven to move up and down along the sliding post 11 through the connecting block 8 threadedly connected to it.

[0034] Furthermore, a transverse sliding groove 2 is provided on the top of the grabbing shell 1 , and the transverse clamping plate 7 slides transversely along the transverse sliding groove 2 through the transverse sliding block 5 .

[0035] A plurality of vertical slide grooves 3 are provided on the top of the grab shell 1 , and the vertical clamping plate 4 slides vertically along the vertical slide grooves 3 via a plurality of vertical sliders 6 .

[0036] The horizontal slider 5 and the vertical slider 6 are both T-shaped, so that when the vertical splint 4 and the horizontal splint 7 move along the vertical slide 3 and the horizontal slide 2, the vertical splint 4 and the horizontal splint 7 will not fall off, and a driving structure is also installed on the grab shell 1. The driving structure is an existing technology and is used to drive the horizontal slider 5 and the vertical slider 6 to move.

[0037] Furthermore, when the vertical splint 4 slides along the vertical slide groove 3 to the minimum distance from the horizontal splint 7, the distance is greater than the width of the horizontal splint 7, thereby avoiding the vertical splint 4 affecting the movement of the horizontal splint 7 when it moves to a certain position.

[0038] Furthermore, the bottom of the grabbing shell 1 is movably connected to two baffles 19, which can be completely separated by moving back to back, completely exposing the bottom of the grabbing shell 1. The two baffles 19 move toward each other to close the bottom of the grabbing shell 1. When the grabbing shell 1 is at the lowest point and ice cubes are grabbed, the two baffles 19 are completely separated and the bottom of the grabbing shell 1 is completely exposed. When the grabbing shell 1 completes grabbing of the ice cubes and needs to be lifted, the two baffles 19 move toward each other to close the bottom of the grabbing shell 1, thereby supporting the ice cubes inside the grabbing shell 1 and reducing the possibility of the ice cubes falling.

[0039] Furthermore, each baffle 19 is movably connected to a connecting rod 18, one end of the connecting rod 18 is movably connected to a driving slider 17, the driving slider 17 is threaded through the outer column 13, the inner wall of the outer column 13 is threaded through the limiting slide 15, the top of the limiting slide 15 is movably connected to the top frame 12, and the bottom end of the limiting slide 15 is movably connected to the base 9 through the bottom plate 16. When the outer column 13 rotates, the driving slider 17 threadedly connected thereto will move up and down along the outer column 13, driving the connecting rod 18 to expand or retract, thereby driving the two baffles 19 to open or merge and close.

[0040] The two baffles 19 are both provided with slots 20 at their joints, so that the baffles 19 can move up and down together with the grab housing 1 without being blocked by the driving slider 17 .

[0041] Furthermore, one end of the outer column 13 is fixedly connected to the limit ring 14. When the driving slider 17 moves up to the highest point of the outer column 13, the connecting rod 18 is completely retracted, and the two baffles 19 close the bottom of the grab shell 1. The range of movement of the connecting rod 18 is limited by the blocking of the limit ring 14. At the same time, when the driving slider 17 moves up to abut against the limit ring 14, if the grab shell 1 continues to rise, the outer column 13 is driven to move up along the limit slide 15 through the action of the limit ring 14. The limit slide 15 is cross-shaped, which can ensure the vertical sliding of the outer column 13 and drive the outer column 13 to rotate together, driving the driving slider 17 to move up or down along the outer column 13 without being affected.

[0042] Furthermore, one end of the sliding post 11 threadedly connected to the connecting block 8 extending to the outside of the top frame 12 is fixedly connected to the driving wheel 22, and one end of the limiting sliding post 15 extending to the outside of the top frame 12 is fixedly connected to the driven wheel 21, and the driven wheel 21 and the driving wheel 22 are meshed and connected through a drive chain 23.

[0043] When the slide post 11 is driven to rotate by the driving device 24, the driving wheel 22 rotates together, and cooperates with the action of the driving chain 23 to drive the driven wheel 21 and the limiting slide post 15 to rotate together. At this time, if the driving slider 17 is in the lowest position, the outer column 13 is driven to rotate through the limiting slide post 15, and the driving slider 17 is driven to move upward. At this time, if the driving slider 17 is in the highest position and the grab shell 1 continues to rise, the outer column 13 is driven to move upward along the limiting slide post 15 through the action of the driving slider 17 and the limiting ring 14. If the grab shell 1 falls, the driving slider 17 is driven to move downward along the outer column 13.

[0044] Furthermore, the number of gear teeth of the driven wheel 21 is smaller than the number of gear teeth of the driving wheel 22, and the gear ratio is inversely proportional to the rotational speed. When the driving device 24 drives the slide column 11 and the driving wheel 22 to rotate, the rotational speed of the driven wheel 21 and the limiting slide column 15 and the outer column 13 is faster than the rotational speed of the slide column 11, so that the speed of the driving slider 17 moving up or down is faster, thereby ensuring that when the grab shell 1 is completely dropped, the baffle 19 is completely separated and will not block the falling of the grab shell 1. When the grab shell 1 rises, although the driving slider 17 drives the baffle 19 to move up at a faster speed, it is blocked by the grab shell 1, so that during the rising stage, the rotational speed of the outer column 13 and the limiting slide column 15 is faster, which does not affect the opposite movement of the baffle 19.

[0045] The following is a detailed description of the working principle of the mechanical automated grasping device.

[0046] like Figure 1-6As shown, multiple uneven ice cubes to be grabbed are covered inside by the grabbing shell 1, and then the vertical clamping plate 4 is slowly moved vertically, and then the horizontal clamping plate 7 is slowly moved horizontally, until all the ice cubes are pushed and regularized in two directions so as to be arranged neatly, and the multiple ice cubes covered by the grabbing shell 1 are clamped tightly by the movement of the vertical clamping plate 4 and the horizontal clamping plate 7. Then, when the slide column 11 is driven to rotate by the driving device 24, the driving wheel 22 rotates together, and cooperates with the action of the driving chain 23 to drive the driven wheel 21 and the limiting slide column 15 to rotate together, and then the outer column 13 is driven to rotate through the limiting slide column 15, so that the driving slider 17 moves upward, and cooperates with the action of the connecting rod 18 to pull the two baffles 19 to move toward each other, thereby forming a sealing effect on the bottom of the grabbing shell 1.
