[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0031] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those skilled in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] See also Figure 1The embodiment of the present application provides a material picking mechanism, including a mounting plate 1, a clamping member 2 and a crank slider transmission mechanism 3, the clamping member 2 is used to clamp the material at the material picking position and release the material at the material discharging position, and the clamping member 2 is slidably connected to the mounting plate 1; the crank slider transmission mechanism 3 is used to drive the clamping member 2 to slide relative to the mounting plate 1, so that the clamping member 2 extends toward the edge direction of the mounting plate 1 or retracts the clamping member 2 toward the center direction of the mounting plate 1; the crank slider transmission mechanism 3 includes a rotating shaft 31, a connecting member 32 and a first driving member 33, and the rotating shaft 31 is rotatably arranged with the mounting plate 1; the connecting member 32 is rotatably connected to the rotating shaft 31 and the clamping member 2 respectively, the connecting member 32 is connected to the eccentric part of the rotating shaft 31, and the output end of the first driving member 33 is connected to the rotating shaft 31; the mounting plate 1 is connected to a second driving member 7, and the second driving member 7 is used to drive the mounting plate 1 to rotate, so that the clamping member 2 on the mounting plate 1 can move to the material picking position and the material discharging position.

[0034] In actual applications, the material picking mechanism can be used to grab battery cells (materials) and transfer the battery cells (materials) from one workstation to another. When the battery cells (materials) need to be taken out from the winding needle, the second driving member 7 drives the mounting plate 1 to rotate and move it to the material picking position. At this time, the first driving member 33 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the connecting member 32 to rotate. The connecting member 32 drives the clamping member 2 to slide on the mounting plate 1, so that the clamping member 2 moves toward the direction close to the battery cell (material) and clamps the battery cell (material). After the clamping member 2 clamps the battery cell (material), the first driving member 33 drives the rotating shaft 31 to rotate in the opposite direction. At this time, the connecting member 32 drives the clamping member 2 to move away from the material picking position, so that the clamping member 2 retracts toward the center position of the mounting plate 1.

[0035] Then, the second driving member 7 drives the mounting plate 1 to rotate to the unloading position, and the rotating shaft 31 moves through the mounting plate 1 but is not connected to the mounting plate 1. In order to ensure that the clamping member 2 and the mounting plate 1 remain relatively stationary, the first driving member 33 also drives the rotating shaft 31 to rotate synchronously, that is, the mounting plate 1 and the rotating shaft 31 rotate synchronously at the same time, so that the clamping member 2 does not slide on the mounting plate 1, ensuring that the clamping member 2 can stably clamp the battery cell (material) to the unloading position. After the mounting plate 1 rotates to the unloading position, the second driving member 7 stops rotating, and the first driving member 33 drives the rotating shaft 31 to rotate, so that the connecting member 32 drives the clamping member 2 to move in the direction close to the unloading position, and then the clamping member 2 releases the battery cell (material) and moves the battery cell (material) to the unloading position.

[0036] It should be noted that the clamping member 2 is a device component used to fix, clamp or hold an object. The clamping member 2 can adopt pneumatic control or mechanical control for its clamping action, and this application does not limit this.

[0037] Compared with the prior art, the present application drives the clamping member 2 to move through the crank slider transmission mechanism 3 to realize the telescopic work of the clamping member 2. The crank mechanism has a small range of motion, a small rotation radius, and a stable and smooth movement. The crank rotation movement is a continuous repetition of circular motion, that is, the rotating shaft 32 can rotate continuously in one direction, and can also realize the telescopic work of the clamping member 2. There is no obvious impact and pause during operation, and it can provide continuous and stable power output, improve positioning accuracy and stability, save device space, and improve production efficiency.

[0038] It should be noted that, since the crank rotation movement is a continuous repetition of circular motion, the first driving member 33 drives the rotating shaft 31 to rotate in the first direction, the rotating shaft 31 drives the connecting member 32 to rotate, and the connecting member 32 drives the clamping member 2 to slide on the mounting plate 1, so that the clamping member 2 moves toward the direction close to the battery cell (material) and clamps the battery cell (material). After the clamping member 2 clamps the battery cell (material), the first driving member 33 can also continue to drive the rotating shaft 31 to rotate in the same direction (first direction), and the connecting member 32 can also drive the clamping member 2 to move in the direction away from the material taking position and retract to the center position of the mounting plate 1.

[0039] See also Figure 1 and Figure 2 The material taking mechanism also includes a monitoring component 8, which is connected to the mounting plate 1 and is used to monitor the position of the clamping member 2.

[0040] In actual applications, in order to realize automatic material picking and unloading, the present application sets up a monitoring component 8 and a control component. The monitoring component 8 is used to monitor the position of the clamping member 2 and transmit the signal to the control component. The control component is used to control the start or stop of the first drive member 33 and the second drive member 7 to ensure that the device can operate automatically and normally without manual operation, thereby realizing mechanical automated production.

[0041] Specifically, see Figure 4 The monitoring component 8 includes a first monitoring component 81 and a second monitoring component 82. The first monitoring component 81 and the second monitoring component 82 are arranged in sequence along the sliding direction of the clamping component 2. The clamping component 2 is provided with a sensing component 12. The first monitoring component 81 and the second monitoring component 82 are respectively used to sense the sensing component 12.

[0042] In actual application, the first monitoring member 81 and the second monitoring member 82 are arranged in sequence along the sliding direction of the clamping member 2, so that when the clamping member 2 slides, the distance between the clamping member 2 and the first monitoring member 81 and the second monitoring member 82 is different. For example, the first monitoring member 81 is set at a position farther from the center of the mounting plate 1 than the second monitoring member 82. When the mounting plate 1 is in the material taking position, the first driving member 33 drives the rotating shaft 31 to rotate, and the rotating shaft 31 drives the connecting member 32 to rotate, and the connecting member 32 drives the clamping member 2 to move in the direction close to the battery cell (material), that is, to move in the direction away from the center position of the mounting plate 1. Therefore, the clamping member 2 moves in the direction close to the first monitoring member 81. When the first monitoring member 81 senses the sensing member 12 on the clamping member 2, that is, the clamping member 2 has extended to the specified position. At this specified position, the clamping member 2 can accurately clamp the battery cell (material). At this time, the first driving member 33 needs to stop rotating to avoid the mismatch between the position of the clamping member 2 and the battery cell (material), which affects the clamping work; After the holding member 2 clamps the battery cell (material), the first driving member 33 drives the rotating shaft 31 to rotate in the opposite direction. At this time, the connecting member 32 drives the holding member 2 to move in the direction close to the center position of the mounting plate 1, so the holding member 2 moves in the direction close to the second monitoring member 82. When the second monitoring member 82 senses the sensing member 12 on the holding member 2, that is, the holding member 2 has retracted to the specified position. At this time, the second driving member 7 drives the mounting plate 1 to rotate, and the first driving member 33 drives the rotating shaft 31 to rotate, so that the holding member 2 and the mounting plate 1 remain in a relatively static state and rotate to the unloading position. Then the second driving member 7 stops, and the first driving member 33 drives the rotating shaft 31 to rotate, so that the holding member 2 moves in the direction close to the unloading position. Therefore, the holding member 2 moves in the direction close to the first monitoring member 81. When the first monitoring member 81 senses the sensing member 12 on the holding member 2, that is, the holding member 2 has extended to the specified position. At this specified position, the holding member 2 releases the battery cell (material) so that the battery cell (material) can accurately enter the next workstation.

[0043] By providing the first monitoring component 81 and the second monitoring component 82 , the clamping component 2 can be accurately controlled to move to a specified position, thereby realizing mechanical automation process control and improving the degree of intelligent production.

[0044] See again Figure 2 The material taking mechanism includes a first fixing member 5, which is connected to the center of the mounting plate 1 and is spaced apart from the mounting plate 1. The end of the first fixing member 5 away from the mounting plate 1 is connected to a monitoring component 8.

[0045] In actual applications, the monitoring component 8 needs to monitor the position of the clamping member 2 in real time, so the monitoring component 8 needs to be installed on the mounting plate 1 and move with the mounting plate 1, so a first fixing member 5 is provided, and the first fixing frame is used to install the monitoring component 8. The first fixing member 5 is spaced apart from the mounting plate 1 to avoid the clamping member 2, and the first fixing member 5 is located at the center of the mounting plate 1 to avoid unbalanced force on the mounting plate 1. The monitoring component 8 is connected to the side of the first fixing member 5 away from the mounting plate 1 to realize the monitoring function of the clamping member 2.

[0046] See again Figure 2 The material taking mechanism further comprises a support member 6, which is connected to one end of the first fixing member 5 away from the mounting plate 1, and one end of the support member 6 is connected to a monitoring component 8.

[0047] In actual applications, the end of the first fixing member 5 away from the mounting plate 1 is connected to a support member 6, and the support member 6 is used to connect the monitoring component 8. On the one hand, the support member 6 plays a supporting role, and on the other hand, the support member 6 can play a balancing role. When there are multiple clamping members 2, there are also multiple groups of monitoring components 8. The multiple groups of monitoring components 8 can be symmetrically arranged about the center of the support member 6 to ensure that the forces in all directions on the mounting plate 1 are balanced.

[0048] The material picking mechanism may further include a balancing member 9. The support member 6 extends to the outside of the mounting plate 1. The balancing member 9 is connected to one end of the support member 6 away from the monitoring component 8. That is, the balancing member 9 is connected to the outside of the mounting plate 1. The balancing member 9 can be used to balance the force on the support member 6, so that the support member 6 is more stable when rotating with the mounting plate 1.

[0049] See also Figure 3 A connecting sleeve 34 is provided on the rotating shaft 31 . The connecting sleeve 34 includes a connecting portion 341 provided on the outer periphery of the rotating shaft 31 . The connecting member 32 is rotatably connected to the connecting portion 341 .

[0050] In actual application, the connecting sleeve 34 can be sleeved on the rotating shaft 31, and the connecting sleeve 34 is provided with at least one connecting portion 341 along its circumference. The connecting member 32 is rotatably connected to the connecting portion 341. Since the connecting portion 341 is located at the eccentric position of the rotating shaft 31, when the rotating shaft 31 rotates, the connecting portion 341 rotates with the rotating shaft 31 and makes a circular motion around the outer side of the rotating shaft 31, and the connecting member 32 moves with the connecting portion 341. At this time, the connecting member 32 drives the clamping member 2 to slide on the mounting plate 1, thereby realizing the conversion of rotation into linear movement.

[0051] See again Figure 2 The material taking mechanism further includes a second fixing member 10, a rotating member 11 and a fixed base 4, the rotating member 11 is rotatably connected to the fixed base 4, and the second fixing member 10 is respectively connected to the rotating member 11 and the mounting plate 1.

[0052] In actual application, the fixed base 4 is used to install the second driving member 7, and a rotating member 11 is rotatably connected to the fixed base 4, and a second fixing member 10 is connected to the rotating member 11. The second fixing member 10 is connected to the mounting plate 1. The second driving member 7 is installed on the fixed base 4, and its driving end is connected to the rotating member 11. The second driving member 7 drives the rotating member 11 to rotate, and the rotating member 11 drives the second fixing member 10 to rotate, and the second fixing member 10 drives the mounting plate 1 to rotate, so that it can switch between the material taking position and the material discharging position.

[0053] See again Figure 2 One end of the rotating shaft 31 passes through the fixed base 4 , and the other end passes through the second fixing member 10 and extends out of the mounting plate 1 .

[0054] In actual applications, in order to save the volume of the entire device, the fixed base 4 can also be used to install the rotating shaft 31. Specifically, one end of the rotating shaft 31 passes through the fixed base 4 and is connected to the driving end of the first driving member 33, and the other end passes through the second fixing member 10 and extends from the mounting plate 1 to facilitate rotational connection with the connecting member 32. In this way, the first driving member 33 and the second driving member 7 can be installed adjacent to each other, effectively saving installation space.

[0055] See also Figure 5 , the number of clamping members 2 is multiple, and the multiple clamping members 2 are symmetrically arranged about the mounting plate 1. In practical applications, in order to improve the production and processing efficiency of battery cells (materials), the clamping members 2 can be set to multiple, and the multiple clamping members 2 work at the same time. The multiple clamping members 2 are symmetrically arranged about the mounting plate 1, which is beneficial to the force balance of the mounting plate 1 and avoids damage to the mounting plate 1 due to excessive force on one side of the mounting plate 1. At the same time, the number of monitoring components 8 should correspond to the number of clamping members 2. Each clamping member 2 corresponds to a group of monitoring components 8. Each group of monitoring components 8 is used to monitor the position of the corresponding clamping member 2 and transmit the position information to the control component. The control component controls the first drive member 33 and the second drive member 7 to start, so as to realize the function of taking and unloading the battery cells (materials).

[0056] The embodiment of the present application also provides a material taking method, using the above-mentioned material taking mechanism, the material taking method comprises the following steps:

[0057] S1. When the mounting plate 1 is at the material taking position, the rotating shaft 31 is rotated, the rotating shaft 31 drives the connecting member 32 to rotate, the connecting member 32 drives the clamping member 2 to approach the material taking position, and the clamping member 2 clamps the material at the material taking position;

[0058] When the mounting plate 1 is at the material picking position, the first driving member 33 drives the rotating shaft 31 to rotate along the first direction (set to the positive direction), the rotating shaft 31 drives the connecting member 32 to move, and the connecting member 32 drives the clamping member 2 to slide on the mounting plate 1 to move toward the material picking position. After the clamping member 2 is extended to the specified position, the first monitoring member 81 senses the sensing member 12 on the clamping member 2 and transmits the sensing information to the control component, and the clamping member 2 moves and clamps the material.

[0059] S2, reversely rotate the shaft 31, the shaft 31 drives the connecting member 32 to rotate, and the connecting member 32 drives the clamping member 2 away from the material taking position;

[0060] That is, after the first monitoring component 81 senses the sensing component 12 on the clamping component 2, the control component controls the first driving component 33 to drive the rotating shaft 31 to rotate along the second direction (set to reverse), the rotating shaft 31 drives the connecting component 32 to rotate in the reverse direction, and the connecting component 32 drives the clamping component 2 to retract toward the center position of the mounting plate 1, and waits for the second monitoring component 82 to sense the sensing component 12 on the clamping component 2 and transmit the sensing information to the control component.

[0061] It should be noted that, in step S2, the rotating shaft 31 may continue to rotate in the forward direction, and the rotating shaft 31 may also drive the connecting member 32 to rotate, so that the connecting member 32 drives the clamping member 2 away from the material taking position.

[0062] S3, synchronously rotate the mounting plate 1 and the rotating shaft 31 in a preset direction until the mounting plate 1 rotates to the unloading position;

[0063] That is, after the second monitoring component 82 senses the sensing component 12 on the clamping component 2, the control component controls the first driving component 33 and the second driving component 7 to rotate synchronously in the same direction, so that the rotating shaft 31 and the mounting plate 1 rotate synchronously, and then the clamping component 2 and the mounting plate 1 are in a relatively static state and rotate to the unloading position.

[0064] S4, rotating the rotating shaft 31, the rotating shaft 31 drives the connecting member 32 to rotate, the connecting member 32 drives the clamping member 2 to approach the material discharge position, and the clamping member 2 releases the material at the material discharge position;

[0065] When the mounting plate 1 rotates to the unloading position, the first driving member 33 rotates along the forward driving shaft 31, the shaft 31 drives the connecting member 32 to rotate, and the connecting member 32 drives the clamping member 2 to move in the direction close to the unloading position. When the clamping member 2 extends to the specified position, the first monitoring component 8 senses the sensing member 12 on the clamping member 2 again and transmits the position information to the control component. At this time, the clamping member 2 releases the battery cell (material) and places the battery cell (material) at the unloading position.

[0066] S5, the rotating shaft 31 is rotated in the opposite direction again, the rotating shaft 31 drives the connecting member 32 to rotate, and the connecting member 32 drives the clamping member 2 away from the unloading position;

[0067] When the control component receives the monitoring information from the first monitoring component 81, the control component controls the first driving component 33 to rotate along the reverse driving shaft 31, and the connecting component 32 drives the clamping component 2 to move toward a position close to the center of the mounting plate 1 until the second monitoring component 82 senses the sensing component 12 on the clamping component 2 and transmits the position information to the control component.

[0068] S6, then synchronously rotate the mounting plate 1 and the rotating shaft 31, wait for the mounting plate 1 to rotate to the material taking position, and repeat S1 to S5.

[0069] When the control component receives the monitoring information of the second monitoring component 82, the control component controls the first driving component 33 and the second driving component 7 to rotate synchronously in the same direction, so that the mounting plate 1 rotates to the material picking position. At this time, the rotating shaft 31 and the mounting plate 1 rotate synchronously in the same direction, and the clamping component 2 and the mounting plate 1 remain relatively stationary and rotate to the material picking position, waiting to pick up material again.

[0070] In a specific application, first, the mounting plate 1 is in the material fetching position, the first driving member 33 rotates along the forward driving shaft 31, the shaft 31 drives the connecting member 32 to rotate, and the connecting member 32 drives the clamping member 2 to slide on the mounting plate 1 to move toward the direction close to the material fetching position. After the clamping member 2 is extended to the specified position, the clamping member 2 clamps the battery cell (material) at this specified position, and the first monitoring member 81 senses the sensing member 12 on the clamping member 2 at this specified position, and transmits the sensing information to the control component; when the control component receives the monitoring information of the first monitoring member 81, the control component controls the first driving member 33 to rotate along the reverse driving shaft 31, and the connecting member 32 drives the clamping member 2 to move toward a position close to the center of the mounting plate 1 until the second monitoring member 82 senses the sensing member 12 on the clamping member 2. Component 12 indicates that the clamping component 2 is retracted to the specified position, and the second monitoring component 82 transmits the position information to the control component again; the control component controls the first driving component 33 and the second driving component 7 to rotate synchronously in the same direction, so that the rotating shaft 31 and the mounting plate 1 rotate synchronously, and then the clamping component 2 and the mounting plate 1 are in a relatively static state and rotate to the unloading position; when the mounting plate 1 rotates to the unloading position, the first driving component 33 drives the rotating shaft 31 to rotate in the forward direction, and the rotating shaft 31 drives the connecting component 32 to rotate, and the connecting component 32 drives the clamping component 2 to move in the direction close to the unloading position. When the clamping component 2 is extended to the specified position, the clamping component 2 releases the battery cell (material) at this specified position, and the first monitoring component 8 senses the sensing component 12 on the clamping component 2 again, and transmits the position information to the control component.

[0071] When the control component receives the monitoring information from the first monitoring component 81, the control component controls the first driving component 33 to rotate along the reverse driving shaft 31, and the connecting component 32 drives the clamping component 2 to move to a position close to the center of the mounting plate 1 until the second monitoring component 82 senses the sensing component 12 on the clamping component 2. At this time, the clamping component 2 retracts to the specified position, and the second monitoring component 82 transmits the position information to the control component. When the control component receives the monitoring information from the second monitoring component 82 again, the control component controls the first driving component 33 and the second driving component 7 to rotate synchronously in the same direction, so that the mounting plate 1 rotates to the material removal position. At this time, the shaft 31 rotates synchronously in the same direction with the mounting plate 1, and the clamping component 2 and the mounting plate 1 remain relatively stationary and rotate to the material removal position. At this point, one material removal work is completed, and this step is repeated until all battery cells (materials) are transported from the material removal position to the unloading position.

[0072] Different from the prior art, the embodiment of the present application provides a material picking mechanism and a material picking method, the material picking mechanism includes a mounting plate 1, a clamping member 2 and a crank slider transmission mechanism 3, the clamping member 2 is used to clamp the material at the material picking position and release the material at the material discharging position, the clamping member 2 is slidably connected to the mounting plate 1; the crank slider transmission mechanism 3 is used to drive the clamping member 2 to slide relative to the mounting plate 1, so that the clamping member 2 extends toward the edge direction of the mounting plate 1 or retracts the clamping member 2 toward the center direction of the mounting plate 1; the crank slider transmission mechanism 3 includes a rotating shaft 31, a connecting member 32 and a first driving member 33, the rotating shaft 31 is rotatably arranged with the mounting plate 1; the connecting member 32 is rotatably connected to the rotating shaft 31 and the clamping member 2 respectively, the connecting member 32 is connected to the eccentric part of the rotating shaft 31, and the output end of the first driving member 33 is connected to the rotating shaft 31; the mounting plate 1 is connected to a second driving member 7, the second driving member 7 is used to drive the mounting plate 1 to rotate, so that the clamping member 2 on the mounting plate 1 can move to the material picking position and the material discharging position. Compared with the prior art, the present application drives the clamping member 2 to move through the crank slider transmission mechanism 3 to realize the telescopic work of the clamping member 2. The crank mechanism has a small range of motion, a small rotation radius, and a stable and smooth movement. The crank rotation movement is a continuous repetition of circular motion, that is, the rotating shaft 32 can rotate continuously in one direction, and can also realize the telescopic work of the clamping member 2. There is no obvious impact and pause during operation, and it can provide continuous and stable power output, improve positioning accuracy and stability, save device space, and improve production efficiency.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
