Description
Technical Field
[0001] The utility model belongs to the technical field of automated production equipment, and in particular relates to a cell turning and unloading mechanism for a battery cell assembly line. Background Art
[0002] With the rapid development of the lithium battery industry, the application of lithium batteries is becoming more and more extensive. In order to meet market demand, lithium battery production equipment is also constantly improving. In order to improve efficiency, the loading, transporting, unloading and other processes on the assembly line are required to be completed as automatically as possible, and the automation integration of production equipment is getting higher and higher. The production process of some batteries requires that the battery cell be flipped before unloading. If the flipping and unloading processes in the unloading process are completed by two sets of mechanisms respectively, it will not only take up more equipment space, but also each action is driven by a different drive mechanism. This requires a high degree of coordination between the actions of each mechanism, and the production debugging is difficult. In addition, the corresponding actions are driven by multiple power sources. Since the connection between the actions takes time, it takes a long time to complete the entire action. In addition, when the assembly line speed is adjusted, each power source must be set separately, which increases the equipment debugging time. To this end, it is necessary to design a set of unloading mechanisms that can integrate the two processes of flipping and unloading to improve efficiency and reduce the occupation of equipment space.

The fourth driving cam 4-1 is used to realize the unloading translation, and the fourth driving cam 4-1 is arranged on the cam driving shaft 5. When the cam driving shaft 5 rotates, it drives the fourth driving cam 4-1 to rotate. The fourth driving cam 4-1 is in contact with the fourth driving rocker 4-2. In this embodiment, a fourth cam contact protrusion 4-2a is arranged on the fourth driving rocker 4-2. During the rotation of the fourth driving cam 4-1, its contour is always in contact with the fourth cam contact protrusion 4-2a, so that the fourth driving rocker 4-2 can be swung up and down according to the contour curve of the fourth driving cam 4-1.
[0051] One end of the fourth driving swing rod 4-2 is sleeved on the first rotating shaft 6, and the other end is hinged to the second vertical connecting rod 4-3. When the fourth driving cam 4-1 rotates, the fourth driving swing rod 4-2 can be driven to swing around the first rotating shaft 6, thereby driving the second vertical connecting rod 4-3 to move up and down along its own axis. The upper end of the second vertical connecting rod 4-3 is connected to the transverse connecting rod 4-4, and the transverse connecting rod 4-4 is set on the third mounting plate 4-5 through a rotating shaft.

The fourth return spring 4-8 provides a force for the fourth driving swing arm 4-2, so that the end connected to the fourth driving swing arm 4-2 and the second vertical connecting rod 4-3 is downward, thereby moving the unloading clamp 4-7 to the material taking side.
[0053] Further optionally, the unloading clamping jaws 4-7 of this embodiment can move up and down in addition to translation. Figure 1 , Figure 8 and Fig. 9As shown, the battery cell unloading and transferring assembly 4 of this embodiment also includes a fifth driving cam 4-9, a fifth driving swing rod 4-10, a fifth vertical lifting connecting rod 4-11, a third power direction conversion swing rod 4-12, and a sixth vertical lifting connecting rod 4-13. The fifth driving cam 4-9 is used to realize unloading and lifting. The fifth driving cam 4-9 is arranged on the cam driving shaft 5. When the cam driving shaft 5 rotates, it drives the fifth driving cam 4-9 to rotate. The fifth driving cam 4-9 is in contact with the fifth driving swing rod 4-10. In this embodiment, a fifth cam contact protrusion 4-10a is arranged on the fifth driving swing rod 4-10. During the rotation process of the fifth driving cam 4-9, its contour is always in contact with the fifth cam contact protrusion 4-10a, so that the fifth driving swing rod 4-10 can be swung up and down according to the contour curve of the fifth driving cam 4-9.
[0054] One end of the fifth driving swing rod 4-10 is sleeved on the second rotating shaft 7, and the other end is hinged to the fifth vertical lifting link 4-11. When the fifth driving cam 4-9 rotates, it can drive the fifth driving swing rod 4-10 to swing around the second rotating shaft 7, thereby driving the fifth vertical lifting link 4-11 to move up and down along its own axis.

The third power direction conversion swing rod 4-12 is set on the second swing rod bracket 4-14 through the rotating shaft, and the second swing rod bracket 4-14 is fixed to the equipment frame. When the fifth vertical lifting link 4-11 moves up and down, it drives the third power direction conversion swing rod 4-12 to rotate around the rotating shaft. The other end of the third power direction conversion swing rod 4-12 is hinged to the sixth vertical lifting link 4-13. When the third power direction conversion swing rod 4-12 rotates around the rotating shaft, it drives the sixth vertical lifting link 4-13 to move up and down along its own axis. The upper end of the sixth vertical lifting link 4-13 is hinged to the third mounting plate 4-5, thereby driving the third mounting plate 4-5 to move up and down. The third mounting plate 4-5 of this embodiment is movably arranged on the material transfer assembly mounting frame 4-15, and the material transfer assembly mounting frame 4-15 is fixed on the equipment frame.
[0055] Optionally, the cell unloading and transferring assembly 4 of this embodiment further includes a fifth return spring 4-16, one end of which is fixed, for example, to the equipment frame, and the other end is connected to the fifth driving swing rod 4-10.

[0056] like Fig.10a and Fig.10b As shown, Fig.10a It is the position state of the unloading clamping jaws 4-7 when clamping the battery cell. Fig.10bIt is the state when the unloading clamp 4-7 is in the unloading position. When different parts of the profile of the fourth driving cam 4-1 contact the fourth cam contact convex part 4-2a, the fourth driving swing arm 4-2 can be driven to rotate around the axis of the first rotating shaft 6, so that the end of the fourth driving swing arm 4-2 hinged with the second vertical connecting rod 4-3 moves up and down. When the end of the fourth driving swing arm 4-2 hinged with the second vertical connecting rod 4-3 moves up and down, the clamp frame 4-6 is further driven to move horizontally through the second vertical connecting rod 4-3 and the transverse connecting rod 4-4. The fourth driving cam 4-1 drives the connecting rod linkage structure composed of the swing rod and the connecting rod to drive the unloading clamp 4-7 to move in the horizontal direction and deliver the battery cell to the unloading position.
[0057] like Fig.11a and Fig.11b As shown, Fig.11a The unloading clamps 4-7 are in the working position. Fig.11b The unloading jaws are in a state of safe height. This embodiment can realize up and down movement when unloading the battery cell. When different parts of the contour of the fifth driving cam 4-9 contact the fifth cam contact protrusion 4-10a arranged on the fifth driving rocker 4-10, the fifth driving rocker 4-10 can be driven to rotate around the axis of the second rotating shaft 7, so that the end of the fifth driving rocker 4-10 hinged with the fifth vertical lifting link 4-11 moves up and down. When the end of the fifth driving rocker 4-10 hinged with the fifth vertical lifting link 4-11 moves up and down, the vertical mounting plate 4-5 is further driven to move up and down through the fifth vertical lifting link 4-11, the third power direction conversion rocker 4-12 and the sixth vertical lifting link 4-13. The fifth driving cam 4-9 drives the connecting rod linkage structure composed of a rocker arm and a connecting rod, so that the driving force is turned and transmitted to the mounting plate 4-5, so as to achieve the purpose of lifting and lowering the mounting plate 4-5, so that the clamping jaw frame 4-6 (unloading clamping jaw 4-7) on the mounting plate 4-5 can be switched between the working position and the safety height.
[0058] The entire action process of the battery cell flipping and unloading mechanism of this embodiment is described below in conjunction with the accompanying drawings:
[0059] In the initial state, the cell positioning head 2-1 of the cell positioning assembly 2 is in a descending state, and the material taking clamp 3-10 is flipped to be on a different side from the cell positioning head 2-1, that is, on the material unloading side;
[0060] When the battery cell is transferred from the previous station to the station where the flipping and unloading mechanism is located, the battery cell positioning assembly 2 is actuated to lift the battery cell positioning head 2-1 upward to perform height positioning on the battery cell that has been moved into position;
[0061] After positioning is completed, the cell flip assembly 3 is activated, and the flip frame 3-9 is flipped, so that the material picking claw 3-10 is flipped to the same side as the cell positioning head 2-1, that is, the material picking side, and the material picking claw 3-10 is lowered to the material picking height to clamp the cell;
[0062] The turning frame 3-9 turns over, so that the material taking clamp 3-10 turns over to the unloading side again, and the unloading clamp 4-7 moves horizontally and descends to the material taking height, and the battery cell is clamped from the material taking clamp 3-10; the material taking clamp 3-10 is reset to a safe height;
[0063] The unloading clamp 4-7 is lifted to a safe height and moved horizontally to deliver the battery cell to the next station, and then lowered to the unloading height to put down the battery cell to complete unloading. After unloading is completed, the unloading clamp 4-7 is reset to a safe height.
[0064] The utility model sets the driving cams of different components on the same cam driving shaft, and the actions of multiple components are driven by one power source. The reduction of the power source can reduce the failure rate of the mechanism. Moreover, the actions of multiple components are executed in sequence when different driving cams on the same cam driving shaft rotate to corresponding positions, which can make the actions of each component compact and coherent, improve time utilization, and thus improve equipment efficiency. The use of the alternation of cam curves to complete the action alternation can also avoid the misorder of actions caused by the inconsistency of the power source, and the execution of the action is more accurate. In addition, the utility model uses one mechanism to complete the two actions of flipping and unloading at one station, reducing the space occupied by the equipment.
[0065] The utility model adopts a multi-cam connecting rod mechanism to transmit driving force and unify the power source. The processing accuracy of the cam is guaranteed by processing means, so as to ensure the correct connection between various actions. The original connection of various actions controlled by electronic control logic is converted into a purely mechanical relationship control action, which improves the reliability of the action and the durability of the mechanism. In addition, no matter how the speed is adjusted within the speed adjustment range of the equipment, the timing relationship between related actions will not be affected, which improves the stability of the mechanism.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
