[0050] Reference Figure 1 and Figure 2 , in some embodiments, the article picking and placing device includes a lifting component 100 and an anti-drop component 200.

[0051] The lifting component 100 is configured to lift an article 300. The lower part of the lifting component 100 lifts the article 300.

[0052] The anti-drop component 200 includes a frame body 1, a linkage mechanism 2 and a limiting member 3. The frame body 1 is provided on the side of the lifting component 100. The linkage mechanism 2 is connected to the frame body 1. The limiting member 3 is connected to the linkage mechanism 2. The limiting member 3 has a first position and a second position. The limiting member 3 is configured to be located obliquely above the article 300 in the first position and below the bottom of the article 300 in the second position. The linkage mechanism 2 is configured to be deformed by force so that the limiting member 3 is located in the first position or the second position, and the limiting member 3 moves along an arc trajectory during the switching process between the first position and the second position to avoid touching the article 300.

[0053] Among them, the linkage mechanism 2 is formed by connecting multiple rods.

[0054] When the limiting member 3 is in the second position, it is located below the bottom of the article 300 and abuts against the bottom of the article 300.

[0055] Optionally, the limiting member 3 includes a rod member or a plate member.

[0056] The anti-drop component 200 provided by the embodiment of the present invention enables the limiting member 3 to be in the first position or the second position through the deformation of the linkage mechanism 2. When the limiting member 3 is in the first position, it is located obliquely above the article 300 and will not interfere with the lifting component 100 when lifting the article 300. After the lifting component 100 lifts the article 300, the limiting member 3 is in the second position, that is, below the bottom of the article 300, and will play a role in supporting the bottom of the article 300 to prevent the article 300 from falling.

[0057] As Figure 2 As shown, in some embodiments, the lowest point of the arc trajectory is lower than the second position and is located outside the article 300, close to the outer edge corner of the article 300. The limiting member 3 first passes through the lowest point of the arc trajectory and then reaches the second position, that is, below the bottom of the article 300. The limiting member 3 can avoid the outer edge corner of the article 300 and prevent contact with the article 300.

[0058] In some embodiments, the linkage mechanism 2 is configured as:

[0059] When the limiting member 3 is in the first position, it is in the first retracted state;

[0060] When the limiting member 3 is in the second position, it is in the second retracted state; and

[0061] During the process of the limiting member 3 switching from the first position to the second position, it first switches from the first retracted state to the deployed state, and then switches from the deployed state to the second retracted state;

[0062] Among them, the linkage mechanism 2 is closer to the lifting component 100 and closer to the lower part of the lifting component 100 in the second retracted state than in the first retracted state.

[0063] When the limiting member 3 is in the first position, the linkage mechanism 2 is in the first retracted state. When the limiting member 3 is in the second position, the linkage mechanism 2 is in the second retracted state. During the process of the limiting member 3 switching from the first position to the second position, the linkage mechanism 2 first switches from the first retracted state to the deployed state, and then switches from the deployed state to the second retracted state. The position switching of the limiting member 3 is realized through the deformation of the linkage mechanism 2. The linkage mechanism 2 has a small space occupation, low cost, simple control, and few failure points.

[0064] In some embodiments, the link mechanism 2 is further configured to:

[0065] During the conversion from the first retracted state to the deployed state, move away from the lifting component 100 and expand towards the lower part of the lifting component 100;

[0066] During the conversion from the deployed state to the second retracted state, move closer to the lifting component 100 and retract towards the lower part of the lifting component 100.

[0067] The link mechanism 2 is close to the hoisting component 100 in the first retracted state and close to the upper part of the hoisting component 100, so as to avoid occupying too much space. During the conversion of the link mechanism 2 from the first retracted state to the deployed state, the link mechanism 2 moves away from the lifting component 100 and expands towards the lower part of the lifting component 100. During the conversion of the link mechanism 2 from the deployed state to the second retracted state, the link mechanism 2 moves closer to the lifting component 100 and retracts towards the lower part of the lifting component 100, so as to avoid occupying too much space.

[0068] In some embodiments, the limiting member 3 is configured to:

[0069] When the link mechanism 2 is in the deployed state, be located at the position on the arc track that is farthest from the lifting component 100;

[0070] During the conversion of the link mechanism 2 from the deployed state to the second retracted state, first pass through the lowest point of the arc track and then reach the second position.

[0071] When the link mechanism 2 is in the deployed state, the limiting member 3 is located at the position on the arc track that is farthest from the lifting component 100. During the conversion of the link mechanism 2 from the deployed state to the second retracted state, the limiting member 3 first passes through the lowest point of the arc track and then reaches the second position, that is, below the bottom of the article 300. The limiting member 3 can avoid the outer edge corners of the article 300 and prevent contact with the article 300.

[0072] The specific shape of the arc track can be determined by modifying the lengths of the links and the positions of the hinge points in the link mechanism 2, so that the limiting member 3 just bypasses the outer edge corners of the article 300 and moves below the bottom of the article 300, and the link mechanism 2 has a certain upward lifting action to make the limiting member 3 abut against the bottom of the article 300. The movement of the limiting member 3 is driven by the deformation of the link mechanism 2. As a whole, the interference range is small, and when the limiting member 3 is in the two states of the first position and the second position, the volume of the link mechanism 2 is very small, occupying very little space, the control is simple, the overall cost is low, and it is stable and reliable.

[0073] In some embodiments, the link mechanism 2 is rotatably connected to the frame body 1. During the deformation process of the link mechanism 2, it will never disengage from the frame body 1 and deforms by rotating relative to the frame body 1, which is beneficial to driving the limiting member 3 to switch between the first position and the second position.

[0074] In some embodiments, the frame body 1 is provided with a hinge point 112 that is rotatably connected to the link mechanism 2. Along the arc trajectory, the distances between the points on the arc trajectory and the hinge point 112 are variable.

[0075] The deformation of the link mechanism 2 drives the limiting member 3 to move in an arc trajectory, enabling the limiting member 3 to switch between the first position and the second position. When the limiting member 3 is in the first position and the second position, the volume of the link mechanism 2 is very small and occupies very little space.

[0076] In some embodiments, the anti-falling assembly 200 further includes a power member 4. The power member 4 is disposed on the frame body 1, and the power end of the power member 4 is configured to perform a vertical linear motion and is drivingly connected to the link mechanism 2 to cause the link mechanism 2 to deform.

[0077] In some related technologies, a swing rod is driven to rotate by a rotary cylinder so that the swing rod is located at the bottom of an article to prevent the article from falling. Since the rotary cylinder is relatively difficult to control, has a small cylinder diameter and a large force arm, there will be a problem of a fast descending speed during the descending process of the swing rod, and a problem of a slow ascending speed during the ascending process of the swing rod, and it is impossible to control the speed of the swing rod well.

[0078] Based on this, in the embodiments of the present invention, the power end of the power member 4 performs a vertical linear motion and is drivingly connected to the link mechanism 2 to cause the link mechanism 2 to deform. Compared with the rotary cylinder, the structure is easy to improve and the control is simple.

[0079] Optionally, the power member 4 includes an oil cylinder, a cylinder or a linear motor.

[0080] In some embodiments, the power member 4 uses a cylinder. The cylinder has more options, the force output is more stable and reliable than that of the rotary cylinder, the price cost is also more reasonable, and in terms of control, only the solenoid valve in the air circuit needs to be controlled, which is overall simple and has few failure points.

[0081] In some embodiments, the frame body 1 includes two opposite guide plates 11. The link mechanism 2 includes two first rods 21. The two first rods 21 are disposed between the two guide plates 11, and each first rod 21 is correspondingly rotatably connected to a guide plate 11.

[0082] One of the two first rods 21 of the two first rods 21 is rotatably connected to one of the two guide plates 11, and the other first rod 21 of the two first rods 21 is rotatably connected to one of the two guide plates 11.

[0083] In some embodiments, the anti-falling component 200 further includes a guide rod 24. Vertical guide grooves 111 are respectively provided on two guide plates 11. The two ends of the guide rod 24 are respectively slidably disposed in the guide grooves 111 on the two guide plates 11, and the link mechanism 2 is connected to the guide rod 24.

[0084] The first end of the guide rod 24 is slidably disposed in the guide groove 111 on one of the two guide plates 11, and the second end of the guide rod 24 is slidably disposed in the guide groove 111 on the other of the two guide plates 11.

[0085] In some embodiments, the frame 1 further includes a mounting plate 12. The mounting plate 12 connects the two guide plates 11. The anti-falling component 200 further includes a power member 4. The power member 4 is disposed on the mounting plate 12 and is drivingly connected to the guide rod 24.

[0086] The power end of the power member 4 is rotatably connected to the guide rod 24. The power member 4 provides power to drive the guide rod 24 to move vertically along the guide groove 11, so as to drive the link mechanism 2 to deform and make the limiting member 3 move back and forth along an arc trajectory.

[0087] Optionally, the anti-falling component 200 further includes a joint. The power end of the power member 4 is rotatably connected to the guide rod 24 through the joint.

[0088] In some embodiments, the link mechanism 2 further includes two second rods 22. The two second rods 22 are respectively rotatably connected to the guide rod 24, and the two second rods 22 are also respectively rotatably connected to the two first rods 21 correspondingly.

[0089] One of the two second rods 22 is rotatably connected to one of the two first rods 21, and the other of the two second rods 22 is rotatably connected to the other of the two first rods 21.

[0090] In some embodiments, the link mechanism 2 further includes two third rods 23 and a rod holder 25. The first ends of the two third rods 23 are respectively rotatably connected to the two second rods 22, the second ends of the two third rods 23 are respectively rotatably connected to the rod holder 25, the two first rods 21 are respectively rotatably connected to the rod holder 25, and the limiting member 3 is connected to the rod holder 25.

[0091] The first end of one of the two third rods 23 is rotatably connected to one of the two second rods 22, and the first end of the other of the two third rods 23 is rotatably connected to the other of the two second rods 22.

[0092] Optionally, the linkage mechanism 2 further includes a first shaft 26 that connects two second rods 22 and two third rods 23.

[0093] Optionally, the linkage mechanism 2 further includes a second shaft that connects two first rods 21 and two second rods 22.

[0094] Wherein, the connection point of the first rod 22 and the second rod 22 is located between the connection point of the first rod 21 and the guide plate 11 and the connection point of the first rod 21 and the rod holder 25.

[0095] The connection point of the second rod 22 and the third rod 23 is located between the connection point of the second rod 22 and the guide rod 24 and the connection point of the second rod 22 and the first rod 21.

[0096] In some embodiments, the rod holder 25 includes a fourth rod 251, a fifth rod 252, and two sixth rods 253. The two third rods 23 are respectively rotatably connected to the fourth rod 251, the two first rods 21 are respectively rotatably connected to the fifth rod 252, the two sixth rods 253 are respectively connected to the fourth rod 251 and the fifth rod 252, and the two ends of the limiting member 3 are respectively correspondingly connected to the two sixth rods 253.

[0097] The first end of the fourth rod 251 and the first end of the fifth rod 252 are both connected to one of the two sixth rods 253, and the second end of the fourth rod 251 and the second end of the fifth rod 252 are both connected to the other of the two sixth rods 253.

[0098] The first end of the limiting member 3 is connected to one of the two sixth rods 253, and the second end of the limiting member 3 is connected to the other of the two sixth rods 253.

[0099] In some embodiments, the sixth rod 253 includes a first rod segment 2531 and a second rod segment 2532. The fourth rod 251 is connected to the first rod segment 2531, the fifth rod 252 is connected to the connection part of the first rod segment 2531 and the second rod segment 2532, the limiting member 3 is connected to the second rod segment 2532, and the second rod segment 2532 inclines towards the lifting assembly 100 relative to the first rod segment 2531.

[0100] In some embodiments, along the arc trajectory, the connection point of the limiting member 3 and the second rod segment 2532 is always closer to the lifting assembly 100 relative to the connection part of the first rod segment 2531 and the second rod segment 2532.

[0101] In some embodiments, the frame 1 is fixed on the lifting assembly 100 so that the entire anti-drop assembly 200 is fixed on the lifting assembly 100.

[0102] Such as Figure 3As shown, the power component 4 uses a cylinder. In Figure a, the limiting component 3 is in the first position, and the linkage mechanism 2 is in the first retracted state. In Figure b, the cylinder extends, and the linkage mechanism 2 is in the deployed state. The limiting component 3 is at the position farthest from the lifting component 100 in the arc trajectory. In Figure c, the cylinder continues to extend, and the linkage mechanism 2 converts from the deployed state to the second retracted state. The limiting component 3 approaches the lowest point of the arc trajectory. In Figure d, the cylinder continues to extend, the limiting component 3 is in the second position, that is, below the bottom of the article 300, and the linkage mechanism 2 is in the second retracted state.

[0103] Figure 3 In it, the telescopic movement of the cylinder will drive the guide rod 24 to move up and down in the guide groove 111, and at the same time drive the linkage mechanism 2 to deform. During the deformation process of the linkage mechanism 2, the limiting component 3 bypasses the edge corner of the article 300 and moves below the bottom of the article 300 to hold the bottom of the article 300 and prevent the article 300 from falling off the lifting component 100.

[0104] As Figure 4a 、 Figure 4b 、 Figure 4c 、 Figure 4d 、 Figure 4e 、 Figure 4f 、 Figure 4g and Figure 4h shown, it is a schematic diagram of several states in the entire deformation process of the linkage mechanism 2 and the entire movement process of the limiting component 3 along the arc trajectory. During the entire movement process, the interference interval of the limiting component 3 is small, and the second position (bottom-holding position) is closer to the central position of the article 300, and the bottom-holding effect is better. At the same time, the entire anti-drop component 200 occupies a small space when in the retracted state.

[0105] The rotational connection in the embodiments of the present invention includes hinge connection.

[0106] In some embodiments, the article 300 has edge corners and can be a square article or a cylindrical article, etc.

[0107] Optionally, the article 300 is an electric core.

[0108] The new energy industry is a future development direction that is relatively emphasized internationally at present. Lithium batteries are a relatively mature and promising direction among them. For lithium batteries, production safety is a key point with the most stringent industry requirements. Because lithium batteries, as energy carriers with relatively high energy density and relatively active chemical properties, will cause heating and spontaneous combustion once a short circuit occurs, and it is very easy to cause serious production accidents. During the grasping and handling process of the electric cores of lithium batteries on the production line, in many cases, there is no insulation treatment. Once the electric core falls, it will be short-circuited with the electric cores below, which is very dangerous. Therefore, various forms of avoiding the falling of the electric core are particularly necessary.

[0109] Based on this, in another aspect of the present invention, a battery production system is provided, which includes a battery cell supply device and the above-mentioned article picking and placing device; the battery cell supply device is configured to provide battery cells; the lifting component 100 in the article picking and placing device is configured to lift battery cells; the limiting member 3 in the anti-falling component 200 is configured to be located obliquely above the battery cell at the first position and below the bottom of the battery cell at the second position.

[0110] In an embodiment of the above battery production system, the article 300 lifted by the lifting component 100 is a battery cell; the anti-falling component 200 is used to prevent the battery cell from falling off the lifting component 100.

[0111] Based on the above embodiments of the present invention, in the case of no explicit negation, the technical features of one embodiment can be beneficially combined with one or more other embodiments.

[0112] Although some specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified or some technical features can be equivalently replaced without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
