Description
Technical Field
[0001] The utility model relates to the technical field of lithium battery production, in particular to a docking and switching mechanism for a lithium battery production line. Background Art
[0002] In lithium battery production lines, the docking switching mechanism is a key device to ensure smooth connection between various processes. Especially in large-scale, high-efficiency production environments, the performance of the docking switching mechanism directly affects the overall operating efficiency and cost of the production line.
[0003] In the prior art, the docking switching mechanism usually adopts a turntable structure driven by a motor to rotate. By setting a number of workstations on the turntable and driving the turntable to rotate by the motor, the workstation switching can be completed. However, due to the large size of the turntable structure, it is usually suitable for the part of the production line where multiple processes are compactly connected and the switching frequency is moderate. For the high switching frequency and two compact processes, the turntable structure occupies a large space, has high manufacturing and maintenance costs, and is difficult to meet the needs of rapid switching, which needs to be solved urgently. Utility Model Content

[0008] Two groups of second driving devices are respectively arranged on the two synchronous mounting plates, and the second driving devices are used to drive the corresponding workstations to slide along the second direction, and the first direction is perpendicular to the second direction.
[0009] By adopting the above technical scheme, since the first direction and the second direction are perpendicular, under the action of the first driving device and the second driving device, each workstation seat is displaced along the L-shaped route, so that the sliding routes of the two workstation seats can be surrounded to form a rectangular closed-loop route. Each time the two workstation seats complete the displacement of the rectangular closed-loop route, the docking and switching of the workstations can be completed, so as to facilitate the transfer of equipment in the subsequent process. At the same time, each workstation seat realizes the function of dual-axis displacement under the action of the first driving device and the second driving device, and can be accurately moved according to the pick-up and placement positions of the equipment in the previous and subsequent processes, without the need for the equipment in this process to adjust the pick-up and placement positions, thereby improving the efficiency of the battery cell docking and switching. Compared with the turntable structure, the two workstation seats only need to perform reciprocating operations along the L-shaped route to complete the battery cell docking and switching operations, and the structure is simple and easy to operate.
[0010] In a preferred example, the present application can be further configured as follows: the first driving device includes two opposite synchronous wheels, a synchronous belt is wound between the two synchronous wheels along the first direction, both of the synchronous wheels are engaged with the synchronous belt, a synchronous motor is fixedly installed on the docking platform, the output shaft of the synchronous motor is fixedly connected to any synchronous wheel, and the two synchronous mounting plates are respectively fixedly connected to the opposite sides of the synchronous belt.
[0011] By adopting the above technical solution, the synchronous motor is started to drive any synchronous wheel to rotate. Under the meshing transmission action of the synchronous wheel and the synchronous belt, the synchronous belt rotates in a cycle, and at the same time, the two synchronous mounting plates located on the opposite sides of the synchronous belt can slide in opposite directions respectively along the first direction, thereby realizing the two workstations sliding in opposite directions respectively along the first direction.
[0012] In a preferred example, the present application may be further configured as follows: guide rails are installed along the first direction at positions of the docking platform corresponding to the two synchronous mounting plates, and the synchronous mounting plates are slidably connected to the guide rails.
[0013] By adopting the above technical solution, a guide rail is arranged on the docking platform along the first direction, which can provide a guiding function for the synchronous mounting plate and improve the sliding stability of the synchronous mounting plate.
[0014] In a preferred example, the present application can be further configured as follows: the second driving device includes a synchronous moving plate and a synchronous cylinder, the synchronous cylinder is fixedly mounted on the synchronous mounting plate along the second direction, the workstation seat is fixedly connected to the synchronous moving plate, and the synchronous moving plate is fixedly connected to the piston rod of the synchronous cylinder.
[0015] By adopting the above technical solution, the synchronous cylinder is started to drive the piston rod to drive the synchronous movable plate to perform telescopic movement, so that the two workstations can slide in opposite directions respectively.
[0016] In summary, the present application includes at least one of the following beneficial technical effects:
[0017] 1. Since the first direction and the second direction are perpendicular to each other, under the action of the first driving device and the second driving device, each workstation seat is displaced along the L-shaped route, so that the sliding routes of the two workstation seats can be surrounded to form a rectangular closed-loop route. Each time the two workstation seats complete the displacement of the rectangular closed-loop route, the docking and switching of the workstations can be completed, so as to facilitate the transfer of the equipment of the subsequent process. At the same time, each workstation seat realizes the function of biaxial displacement under the action of the first driving device and the second driving device, and can be accurately moved according to the pick-up and placement positions of the equipment of the previous and subsequent processes, without the need for the equipment of the process to adjust the pick-up and placement positions, thereby improving the efficiency of the docking and switching of the battery cells. Compared with the turntable structure, the two workstation seats only need to perform reciprocating operations along the L-shaped route to complete the docking and switching of the battery cells, and the structure is simple and easy to operate.
[0018] 2. Start the synchronous motor to drive any synchronous wheel to rotate. Under the meshing transmission of the synchronous wheel and the synchronous belt, the synchronous belt rotates in a circle, and at the same time, the two synchronous mounting plates located on the opposite sides of the synchronous belt can slide in the opposite direction respectively along the first direction, thereby realizing the opposite sliding of the two workstations in the first direction respectively.

[0026] A lithium battery production line docking and switching mechanism of the present application is described below with reference to the accompanying drawings.
[0027] like Figure 1 and Figure 2As shown, the docking switching mechanism of the lithium battery production line includes a docking platform 1, on which two synchronous mounting plates 2 are slidably arranged, and a workstation 3 is slidably arranged on the synchronous mounting plate 2, and the workstation 3 is used to place the battery cell 4, and the workstation 3 can be a fixture, a tray or other structure suitable for fixing the battery cell 4 to ensure the stability and safety of the battery cell 4 when moving, and a first driving device 5 is arranged on the top of the docking platform 1, and the first driving device 5 is used to simultaneously drive the two synchronous mounting plates 2 to slide in the opposite direction along the first direction, and each synchronous mounting plate 2 is provided with a second driving device 8, and the second driving device 8 is used to drive the corresponding workstation 3 to slide along the second direction, wherein the first direction and the second direction are perpendicular to each other, so that Under the action, each workstation seat 3 is displaced along the L-shaped route so that the sliding routes of the two workstation seats 3 are surrounded to form a rectangular closed-loop route. Each time the two workstation seats 3 complete the displacement of the rectangular closed-loop route, the docking and switching of the workstations can be completed, so as to facilitate the transfer of equipment in the subsequent process. At the same time, each workstation seat 3 realizes the function of dual-axis displacement under the action of the first drive device 5 and the second drive device 8, and can be accurately moved according to the pick-up and placement positions of the equipment in the previous and subsequent processes, without the need for the equipment in this process to adjust the pick-up and placement positions, thereby improving the efficiency of the battery cell docking and switching. Compared with the turntable structure, the two workstation seats 3 only need to perform reciprocating operations along the L-shaped route to complete the battery cell docking and switching operations, which has a simple structure and is easy to operate.
[0028] It should be noted that if Figure 2 As shown, the two workstations 3 can realize the position exchange between the two workstations 3 under the action of the first drive device 5 and the second drive device 8, that is, after one of the workstations 3 completes the material picking work of the battery cell 4 in the previous process, it can be transferred to the position of the other workstation 3 under the action of the first drive device 5 and the second drive device 8, and the pick-up and placement mechanism 6 of the previous and subsequent processes does not need to adjust the grasping position through program detection or judgment of the actual position of the battery cell 4, and the position to which the two workstations 3 need to move, that is, the actual position for picking and placing materials, is adjusted according to the position of the pick-up and placement mechanism 6 of the previous and subsequent processes, wherein the pick-up and placement mechanism 6 of the previous and subsequent processes can be various types of equipment such as multi-axis manipulators, pneumatic fingers, suction cups, etc. This is common knowledge of the staff in this field and will not be elaborated here.
[0029] Specifically, Figure 1As shown, the first driving device 5 includes two opposite synchronous wheels 51, a synchronous belt 52 is wound between the two synchronous wheels 51 along the first direction, and the two synchronous wheels 51 are meshed with the synchronous belt 52. The docking table 1 is fixedly installed with a synchronous motor 53, and the output shaft of the synchronous motor 53 is fixedly connected to any synchronous wheel 51. The two synchronous mounting plates 2 are respectively fixedly connected to the opposite sides of the synchronous belt 52. Under the meshing transmission action of the synchronous wheels 51 and the synchronous belt 52, the synchronous belt 52 rotates in a circle, and at the same time, the two synchronous mounting plates 2 located on the opposite sides of the synchronous belt 52 can slide in the opposite direction respectively along the first direction, thereby realizing that the two workstations 3 slide in the opposite direction respectively along the first direction.
[0030] Furthermore, guide rails 7 are installed along the first direction at the positions of the docking platform 1 corresponding to the two synchronous mounting plates 2, and the synchronous mounting plates 2 are slidably connected to the guide rails 7. By arranging the guide rails 7 along the first direction on the docking platform 1, a guiding effect can be provided to the synchronous mounting plates 2, and the sliding stability of the synchronous mounting plates 2 can be improved.
[0031] In addition, the second driving device 8 includes a synchronous moving plate 81 and a synchronous cylinder 82. The synchronous cylinder 82 is fixedly installed on the synchronous mounting plate 2 along the second direction. The work station seat 3 is fixedly connected to the synchronous moving plate 81. The synchronous moving plate 81 is fixedly connected to the piston rod of the synchronous cylinder 82. By starting the synchronous cylinder 82 to drive the piston rod to drive the synchronous moving plate 81 to perform telescopic movement, the two work stations 3 can slide in opposite directions respectively along the second direction.
[0032] The implementation principle of the docking switching mechanism of a lithium battery production line in the embodiment of the present application is as follows: after the previous process is completed and the battery cell 4 is placed on one of the workstations 3, under the action of the synchronous cylinder 82, the synchronous moving plate 81 drives the workstation 3 to move along the second direction to avoid interference between the two workstations 3 when they move in the opposite direction in the first direction, and then the synchronous motor 53 is started to drive any synchronous wheel 51 to rotate, and under the meshing transmission action of the synchronous wheel 51 and the synchronous belt 52, the synchronous belt 52 is cyclically rotated, and at the same time, the two synchronous installations located on the opposite sides of the synchronous belt 52 are caused to rotate. The plate 2 can respectively drive the synchronous moving plate 81 to move, thereby driving the work station seat 3 to slide in the opposite direction along the first direction, and then cooperate with the displacement of the synchronous moving plate 81 in the second direction, each work station seat 3 can be displaced along the L-shaped route, so that the sliding routes of the two work station seats 3 form a rectangular closed-loop route. The two work station seats 3 complete the docking and switching of the work stations each time they complete the displacement of the rectangular closed-loop route. Compared with the turntable structure, the two work station seats 3 only need to perform reciprocating operations along the L-shaped route to complete the docking and switching operations of the battery cells. The structure is simple and easy to operate.
[0033] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
