[0036] refer to Figure 1 、 Figure 2 and Figure 3 In some embodiments, the article picking and placing device includes a lifting component 100 and an anti-drop component 200.

[0037] The lifting assembly 100 is configured to lift an object 300. The lower portion of the lifting assembly 100 lifts the object 300.

[0038] The anti-drop assembly 200 includes a fixing plate 1 , a guide mechanism and a limiting member 4 .

[0039] The fixing plate 1 is fixed to the lifting assembly 100, and a guide groove 101 is provided on the fixing plate 1; the guide mechanism is configured to move under the guiding action of the guide groove 101; the limiter 4 is connected to the guide mechanism, and the limiter 4 has a first position and a second position. When the limiter 4 is in the first position, it is located obliquely above the article 300, and when the limiter 4 is in the second position, it is located below the bottom of the article 300; wherein, the guide groove 101 is configured to guide the movement of the guide mechanism so that it is located in the first position or the second position.

[0040] In the embodiment of the present invention, a fixing plate 1 is provided on the side of the lifting component 100, and a guide groove 101 is provided on the fixing plate 1. The movement of the guide mechanism is guided by the guide groove 101, so that the limit member 4 switches between the first position and the second position. When the limit member 4 is in the second position, it is located below the bottom of the article 300 and abuts against the bottom of the article 300. The limit member 4 can play a bottoming role for the article 300 to prevent the article 300 from falling off. The entire anti-drop assembly 200 has a compact structure, a small interference space, low cost, simple control, and few failure points.

[0041] In some embodiments, the anti-drop assembly 200 includes two fixing plates 1 , a sliding rod 2 , two guide rods 3 and a limiting member 4 .

[0042] The two fixing plates 1 are arranged opposite to each other and are respectively fixed to the lifting assembly 100 . The two fixing plates 1 are respectively provided with a guide groove 101 .

[0043] The two ends of the slide bar 2 pass through the guide grooves 101 on the two fixing plates 1. The first end of the slide bar 2 passes through the guide groove 101 on one of the two fixing plates 1, and the second end of the slide bar 2 passes through the guide groove 101 on the other of the two fixing plates 1.

[0044] The first ends of the two guide rods 3 are rotatably connected to the two ends of the slide rod 2. The first end of one of the two guide rods 3 is rotatably connected to the first end of the slide rod 2, and the first end of the other of the two guide rods 3 is rotatably connected to the second end of the slide rod 2.

[0045] The two ends of the limiter 4 are rotatably connected to the second ends of the two guide rods 3. The first end of the limiter 4 is rotatably connected to the second end of one of the two guide rods 3, and the second end of the limiter 4 is rotatably connected to the second end of the other of the two guide rods 3.

[0046] The limiting member 4 has a first position and a second position. When the limiting member 4 is in the first position, it is located obliquely above the article 300 . When the limiting member 4 is in the second position, it is located below the bottom of the article 300 and abuts against the bottom of the article 300 .

[0047] The guide groove 101 is configured to guide the movement of the slide bar 2 so that the slide bar 2 drives the limiting member 4 to move through the guide bar 3 so that the limiting member 4 is located at the first position or the second position.

[0048] Optionally, the limiting member 4 includes a rod or a plate.

[0049] The two guide rods 3 and the limiting member 4 form a U-shaped bottom structure.

[0050] The two fixing plates 1 of the anti-drop assembly 200 are fixed to the side of the lifting assembly 100 , and the anti-drop assembly 200 can be quickly removed from the lifting assembly 100 as a whole.

[0051] The picking and placing process of the article picking and placing device is as follows: the lifting component 100 lifts the article 300, and the anti-drop component is in the initial state, and the limiter 4 is in the first position. During the process of switching the anti-drop component from the initial state to the bottom-covering state, the slide bar 2 is forced to move along the guide groove 101, and the slide bar 2 drives the two guide rods 3 to move, and the two guide rods 3 drive the limiter 4 to move, so that the limiter 4 moves from the first position to the second position, and is finally located in the second position. The limiter 4 is located below the bottom of the article 300 and abuts against the bottom of the article 300, playing a bottom-covering role for the article 300 to prevent the article 300 from falling off, and the anti-drop component is in the bottom-covering state.

[0052] In the embodiment of the present invention, two fixed plates 1 are provided on the side of the lifting assembly 100, and guide grooves 101 are provided on the two fixed plates 1. The movement of the slide bar 2 is guided by the two guide grooves 101, so that the limit member 4 switches between the first position and the second position. When the limit member 4 is in the second position, it is located below the bottom of the article 300 and abuts against the bottom of the article 300. The limit member 4 can play a bottoming role for the article 300 to prevent the article 300 from falling off. The entire anti-drop assembly 200 has a compact structure, small interference space, low cost, simple control, and few failure points.

[0053] In some embodiments, the guide groove 101 includes a first groove section 111 and a second groove section 112 . The first groove section 111 extends in a vertical direction. The second groove section 112 connects to the first groove section 111 and extends obliquely downward away from the lifting assembly 100 .

[0054] The first groove section 111 is arranged above the second groove section 112. The movement of the slide bar 2 is guided by the first groove section 111 and the second groove section 112, so that the limit member 4 switches between the first position and the second position. The structure is compact and the interference space is small, so that the limit member 4 can play a bottoming role for the article 300 and prevent the article 300 from falling off.

[0055] In some embodiments, in the initial state of the anti-drop assembly 200, the slide bar 2 is located at the end of the first slot section 111 away from the second slot section 112, and the limit member 4 is located at the first position; when the slide bar 2 is forced to move toward the connection between the first slot section 111 and the second slot section 112, the limit member 4 moves from the first position to the second position; when the slide bar 2 continues to be forced to move from the connection between the first slot section 111 and the second slot section 112 to the end of the second slot section 112 (away from the first slot section 111), and reaches the end of the second slot section 112, the limit member 4 is located at the second position.

[0056] Optionally, the first slot section 111 is a straight slot, and the second slot section 112 is a straight slot.

[0057] In some embodiments, the stopper 4 is configured as:

[0058] When the sliding bar 2 is located at the connection between the first slot section 111 and the second slot section 112 , it is located below the outer side of the object 300 .

[0059] When the sliding bar 2 is located at the end of the second slot section 112 , it is located below the bottom of the object 300 and abuts against the bottom of the object 300 .

[0060] In the initial state of the anti-drop assembly 200, the limiting member 4 is located obliquely above the object 300. When the anti-drop assembly 200 switches from the initial state to the bottom-covering state, the slide bar 2 first moves vertically along the first slot section 111, driving the limiting member 4 to move vertically so that the limiting member 4 is located below the outer side of the object 300. Then, the slide bar 2 moves obliquely downward away from the object 300 along the second slot section 112. The slide bar 2 drives the limiting member 4 to move toward the object 300 through the guide rod 3, and moves to the bottom of the object 300, abutting the bottom of the object 300, thereby covering the object 300 and preventing the object 300 from separating from the lifting assembly 100. At this time, the anti-drop assembly 200 is in the bottom-covering state. The entire movement trajectory of the limiting member 4 has little interference with the space, and the bottom-covering position is closer to the center of the object 300, which has a better bottom-covering effect, low overall cost, and is stable and reliable.

[0061] In some embodiments, the anti-drop assembly further includes a rotating plate 5 , which is rotatably connected to the two fixed plates 1 , and the two guide rods 3 pass through the rotating plate 5 respectively.

[0062] The guide rod 3 will not be too far away from the fixed plate 1 under the restriction of the rotating plate 5, and the structure is compact. The rotating plate 5 will not limit the movement of the slide rod 2 along the guide groove 101, nor will it limit the rotation of the guide rod 3 relative to the fixed plate 1, but will facilitate the rotation of the guide rod 3 relative to the fixed plate 1.

[0063] In some embodiments, the anti-drop assembly 200 further includes two linear bearings 6 provided on the rotating plate 5 , and the two guide rods 3 are respectively provided on the rotating plate 5 through the two linear bearings 6 . The two fixed plates 1 are located between the two linear bearings 6 .

[0064] One of the two guide rods 3 is passed through the rotating plate 5 via one of the two linear bearings 6, and the other of the two guide rods 3 is passed through the rotating plate 5 via the other of the two linear bearings 6. The movement of the two guide rods 3 is guided by the two linear bearings 6.

[0065] Optionally, two linear bearings 6 are fixed vertically on the rotating plate 5 at intervals.

[0066] In some embodiments, the rotating plate 5 includes a first plate 51 and two second plates 52, the two second plates 52 are fixed to the first plate 51, and the two second plates 52 are respectively hinged to the two fixed plates 1, the two guide rods 3 pass through the first plate 51 respectively, and the two second plates 52 are located between the two guide rods 3 and the penetration point of the first plate 51.

[0067] Optionally, the two second plates 52 are respectively arranged perpendicular to the first plate 51 .

[0068] One of the two second plates 52 is hinged to one of the two fixing plates 1 , and the other of the two second plates 52 is hinged to the other of the two fixing plates 1 .

[0069] One of the two second plates 52 is located between the two fixed plates 1 , and the other second plate 52 is located outside the fixed plate 1 hinged to it, that is, on the side of the fixed plate 1 hinged to it away from the other fixed plate 1 .

[0070] The guide rod 3 can reciprocate in a direction perpendicular to the first plate 51 through the guidance of the linear bearing 6 , and the linear bearing 6 can rotate around the hinge point 13 between the second plate 52 and the fixed plate 1 .

[0071] In some embodiments, the anti-drop assembly further includes a rotating plate 5, which is rotatably connected to the two fixed plates 1, and the two guide rods 3 respectively pass through the rotating plate 5. The rotating plate 5 is configured to rotate relative to the fixed plates 1 during the movement of the sliding bar 2 from the connection between the first slot segment 111 and the second slot segment 112 to the end of the second slot segment 112.

[0072] The first slot section 111 extends vertically, and the slide bar 2 moves along the first slot section 111, driving the guide bar 3 to move vertically. As the slide bar 2 moves from the connection between the first slot section 111 and the second slot section 112 to the end of the second slot section 112, the slide bar 2 moves diagonally, driving the guide bar 3 to rotate relative to the fixed plate 1, and the guide bar 3 drives the rotating plate 5 to rotate relative to the fixed plate 1.

[0073] like Figure 1 ,like Figure 4a and Figure 4b As shown, in some embodiments, the rotating plate 5 is rotatably connected to the two fixed plates 1, and the rotating plate 5 and the two fixed plates 1 each have a hinge point 13, and the hinge points 13 of the rotating plate 5 and the two fixed plates 1 are respectively located on the central axis L of the first slot section 111 on the corresponding fixed plate 1.

[0074] like Figure 4a and Figure 4b As shown, the central axis L of the first slot segment 111 refers to the center line of the projection image of the first slot segment 111 on the vertical plane, and the central axis L extends along the vertical extension direction of the first slot segment 111.

[0075] like Figure 1 and Figure 2 As shown, in some embodiments, the anti-drop assembly 200 further includes two springs 7 , which are respectively sleeved on the two guide rods 3 and located between the rotating plate 5 and the sliding rod 2 .

[0076] The spring 7 is a compression spring. When the external force on the slide bar 2 disappears, the limiter 4 moves from the bottom of the object 300 to the outside and bottom of the object 300 under the elastic restoring force of the spring 7, and moves diagonally above the object 300, and then returns to the first position.

[0077] In some embodiments, the anti-drop assembly 200 also includes a mounting plate 8 and a power member 9, the mounting plate 8 connects the two fixed plates 1, the power member 9 is fixed on the mounting plate 8, the power end of the power member 9 moves vertically and is driven to be connected to the slide rod 2 so that the slide rod 2 moves along the guide groove 101.

[0078] In some related technologies, a rotary cylinder is used to drive the pendulum arm to rotate so that the pendulum arm is located at the bottom of the object to prevent the object from falling. Since the rotary cylinder is relatively difficult to control, the cylinder diameter is small, and the lever arm is large, the pendulum arm will descend quickly during the descent process, and will ascend slowly during the ascent process.

[0079] Based on this, the power end of the power part 9 used in the embodiment of the present invention is in vertical linear motion, and is driven and connected to the slide rod 2 so that the slide rod 2 moves along the guide groove 101, and then drives the limit part 4 to move through the guide rod 3. The driving form of the vertical linear motion of the power end of the power part 9 is simpler than the rotating cylinder in controlling the movement speed of the slide rod 2.

[0080] Optionally, the power member 9 includes an air cylinder, an oil cylinder or a linear motor.

[0081] Pneumatic cylinders offer a wide range of options. Compared to rotary cylinders, pneumatic cylinders offer more stable and reliable force output, and are more cost-effective. Control only requires controlling the solenoid valve in the air circuit, making the overall process simpler and reducing potential problems.

[0082] In some embodiments, the anti-drop assembly 200 also includes a joint 10, a belt 11 and a pulley 12. The joint 10 is arranged at the power end of the power part 9, and the pulley 12 is fixed to the joint 10. The first end of the belt 11 is connected to the mounting plate 8, and the second end of the belt 11 passes around the pulley 12 and is connected to the slide rod 2.

[0083] The power end of the power member 9 is connected to the joint 10, and the joint 10 is provided with a pulley 12. One end of the belt 11 is fixedly connected to the mounting plate 8, and the other end of the belt 11 passes around the pulley 12 to connect the slide rod 2. Since the belt 11 can be deformed and moved under force, during the movement of the slide rod 2 along the second groove section 112, the vertical movement of the power end of the power member 9 will be ensured by the degree of freedom generated by the belt 11, and there will be no restriction on the rotation of the guide rod 3 and the rotating plate 5 relative to the fixed plate 1.

[0084] In some embodiments, there are two pulleys 12, which are respectively arranged at both ends of the joint 10, and there are two belts 11. The first ends of the two belts 11 are respectively connected to the mounting plate 8, and the second ends of the two belts 11 are respectively passed around the two pulleys 12 and connected to the slide rod 2.

[0085] The first end of one of the two belts 11 is connected to the mounting plate 8, and the second end passes around one of the two pulleys 12 to be connected to the slide bar 2. The first end of the other belt 11 is connected to the mounting plate 8, and the second end passes around the other of the two pulleys 12 to be connected to the slide bar 2.

[0086] Two pulleys 12 are respectively provided at the two ends of the joint 10, and two belts 11 are respectively passed around a pulley 12. The two belts 11 are respectively provided on both sides of the power part 9 and are located between the two fixed plates 1, which can make the movement of the limit part 4 smooth and avoid interference with the movement of the power end of the power part 9.

[0087] Two pulleys 12 are provided on the joint 10, and the first ends of the two belts 11 are respectively connected to the mounting plate 8, and the second ends of the two belts 11 are respectively passed around the two pulleys 12 and connected to the slide rod 2. When the power end of the power part 9 is extended, it will drive the pulley 12 to move downward. Driven by the pulley 12, the belt 11 pulls the slide rod 2 downward along the guide groove 101. The moving distance of the pulley 12 is half of the moving distance of the slide rod 2, which can produce an amplifying effect on the driving stroke of the power end of the power part 9.

[0088] The working process of a specific embodiment of the article picking and placing device is described below:

[0089] The lower portion of the lifting assembly 100 lifts the object 300 .

[0090] When the anti-drop assembly 200 is in an initial state, the slide bar 2 is located at an end of the first slot section 111 of the guide slot 101 away from the second slot section 112 , and the limiting member 4 is located obliquely above the object 300 .

[0091] During the switching process of the anti-drop assembly 200 from the initial state to the bottom-covering state: the power end of the power member 9 drives the joint 10 to move downward, the joint 10 drives the pulley 12 to move downward, and the belt 11 pulls the slide bar 2 to move vertically along the first slot section 111 under the action of the pulley 12. During the downward movement of the slide bar 2, the guide bar 3 is driven to move downward under the action of the linear bearing 6, and the limit member 4 moves downward at the same time. In this process, the spring 7 is compressed between the slide bar 2 and the rotating plate 5. When the slide bar 2 moves downward and slides to the first slot section 111 and the second slot section 11 2, the limiting member 4 is located below the outer side of the article 300, the sliding bar 2 continues to move along the second slot section 112, the guide bar 3 begins to swing relative to the fixed plate 1, and the rotating plate 5 rotates relative to the fixed plate 1 at the hinge point 13, so that the limiting member 4 moves toward the bottom of the article 300. After the sliding bar 2 moves to the end of the second slot section 112 away from the first slot section 111, the limiting member 4 moves to just below the bottom of the article 300 and moves upward until it abuts against the bottom of the article 300. At this time, the anti-drop assembly 200 is in a bottom-covering state.

[0092] When the power end of the power part 9 moves upward, the elastic restoring force of the spring 7 will push the guide rod 3 and the slide rod 2 to reset. The entire process is opposite to the above process, completing the switching of the anti-drop assembly 200 from the bottom-covering state to the initial state.
