In the lithium battery assembling process, one step is to cover a shell-shaped workpiece on a plurality of stacked battery cores to assemble a battery pack.

Fig. 1 is a schematic three-dimensional structure of a workpiece. As shown in fig. 1, the workpiece 1 extends in a direction and has a U-shaped cross section. The workpiece 1 comprises a bottom wall 1a and two side walls 1 b. The outer side of each side wall 1b is also provided with a portion to be clamped 1 c.

Fig. 2 to 4 are a front view, a left side view and a top view of the transfer line for transferring the workpiece, respectively. As shown in fig. 2 to 4, the transmission line 10 includes a first support 11. The first support 11 is provided with a plurality of rollers 12 at intervals along the conveying direction in a rotatable manner. The first support 11 is provided with connecting plates 13 at intervals in a direction perpendicular to the conveying direction of the work 1. The connecting plate 13 is fixedly provided with a guide plate 14. The adjacent rollers 12 are connected by a conveyor belt 15. At least one of the rollers 12 is a motorized roller. The motorized rollers are powered so that the other rollers 12 are driven in rotation in synchronism by the conveyor belt 15.

The workpiece 1 is placed on a number of rollers 12. The roller 12 rotates to drive the workpiece 1 to move. The guide plate 14 is used to guide the movement of the workpiece 1. In order to increase the contact area of the workpiece 1 with the transfer line 10 and to increase the driving force, the bottom wall 1a of the workpiece 1 is in contact with the rollers 12.

After the workpiece 1 is conveyed to the preset station by the conveying line 10, the posture of the workpiece 1 on the conveying line 10 is inconvenient for the manipulator to grab, and in addition, the position of the workpiece 1 is not accurate, so that the manipulator cannot grab the workpiece 1 directly from the conveying line 10 and cover the workpiece 1 on a plurality of stacked battery cores.

The turnover device provided by the application can be used for taking down the workpiece 1 from the transmission line 10, fixing the workpiece 1 and turning over the workpiece 1 by a preset angle. After that, the robot can grip the portions to be gripped 1c on both side walls, transfer the workpiece 1 to the assembly station, and thereby cover the workpiece 1 on the stacked plurality of cells.

Of course, the turning device of the present application is not limited to be applied to the above-described scenario. In addition, the workpiece 11 may have a hemispherical shell shape or other shapes.

Fig. 5 is a schematic structural diagram of a flip device and a transmission line according to an embodiment of the present application. Fig. 6 and 7 are top and left side views, respectively, of the flipping unit of fig. 5. As shown in fig. 5 to 7, the turnover device includes: a handling assembly 20, a grasping assembly 40, and a flipping assembly 30.

After the grasping assembly 40 grasps the workpiece 1 from the carrying assembly 20, the turning assembly 30 rotates the grasping assembly 40 by a predetermined angle. In the present embodiment, the predetermined angle is 180 ° so that the cavity of the workpiece 1 opens toward the transfer line 10. Therefore, the workpiece 1 is automatically taken off from the transmission line 10, the workpiece 1 is fixed, and the workpiece 1 is turned over by a preset angle, so that the cost is reduced, and the efficiency is improved.

As shown in fig. 5, the flipping assembly 30 may include a movable base 32, a flipping base 34, and a first driver 35. The flip seat 34 is pivotally connected to the movable seat 32. The first driver 35 is used for driving the overturning seat 34 to rotate. The gripping assembly 40 is disposed on the flipping base 34.

After the grasping assembly 40 grasps the workpiece 1, the first actuator 35 is operated to rotate the rotatable base 34 relative to the movable base 32, thereby rotating the grasping assembly 40. In this embodiment, two movable seats 32 are provided. Both ends of the roll-over stand 34 are respectively rotatably connected to the movable stand 32, so that both ends of the roll-over stand 34 are stressed in a balanced manner, and a stable state can be maintained during rotation. The inverting base 34 can carry the workpiece 1 after the gripping assembly 40 grips the workpiece 1, in addition to driving the gripping assembly 40 to rotate, so that the gripping assembly 40 can hold the workpiece 1 more stably.

Specifically, as shown in fig. 5, the flipping base 34 may include a flipping body 341 and a rotating shaft 342. The turnover body 341 is long. The rotation shaft 342 is disposed at an end of the turnover body 341 and rotatably connected to the movable base 32. In this embodiment, two movable seats 32 are provided, and correspondingly, two rotating shafts 342 are provided, which are respectively provided at two ends of the turning main body 341. The movable seat 32 may be a bearing seat. The shaft 342 may be rotatably coupled to the movable mount via a bearing (not visible). Among them, the turnover body 341 may be a frame structure to reduce weight, thereby reducing a load of the first driver 35. The gripping assembly 40 is disposed on the overturning body 341. The first driver 35 may be a motor. The motor is disposed on the movable seat 32, and an output shaft thereof is fixedly connected to the rotating shaft 342. The turnover main body 341 is directly driven to rotate by the motor, and the structure is simple.

To prevent the roll-over stand 34, the gripping assembly 40, or the workpiece 1 already fixed to the roll-over stand 34 from colliding with other parts near the roll-over stand 34 while the roll-over stand 34 is rotating, the roll-over assembly 30 further includes: a mounting bracket 31 and a second actuator 33. The movable seat 32 is movably connected to the mounting frame 31 and can reciprocate in a first direction and a direction opposite to the first direction. Specifically, the movable seat 32 may be movably connected to the mounting frame 31 by a sliding block assembly (not shown). The second actuator 33 is used for driving the movable base 32 to move so as to drive the gripping assembly 40 to approach or move away from the carrying assembly 20. The second driver 33 may be a pneumatic cylinder. The cylinder body of the cylinder is fixedly arranged on the mounting frame 31, and the piston rod is fixedly connected with the movable seat 32.

After the conveying assembly 20 conveys the workpiece 1 away from the conveying line 10, the second driver 33 operates to drive the inverting base 34 to approach the conveying assembly 20, so that the gripping assembly 40 grips the workpiece 1 from the conveying assembly 20. Then, the second driver 33 is operated to drive the inverting seat 34 away from the carrier assembly 20 and move to a predetermined position. At the predetermined position, the turning base 34 is clear, and the process of turning the gripping assembly 40 by the turning base 34 is not interfered at the predetermined position.

As shown in fig. 5, in order to allow at least a portion of the gripping assembly 40 to enter or exit the cavity of the workpiece 1, thereby facilitating the gripping assembly 40 to grip the workpiece 1 or release the workpiece 1, the gripping assembly 40 is further movably disposed on the flipping base 34 and can reciprocate in the second direction and in the opposite direction of the second direction. The gripping assembly 40 may be movably coupled to the flipping base 34 by a sliding track slider assembly (not shown). Meanwhile, the flipping assembly 30 further includes a third driver 36. Third actuator 36 is used to move gripper assembly 40. The third actuator 36 may be a pneumatic cylinder.

In this embodiment, two gripping assemblies 40 are provided at intervals in the second direction. Correspondingly, two third drivers 36 are provided. Before the inverting base 34 approaches the carrier assembly 20, the two third actuators 36 are actuated to move the two gripper assemblies 40 away from each other to avoid the workpiece 1. After the inverting base 34 approaches the carrying assembly 20, the two third drivers 36 are operated to drive the two gripping assemblies 40 together, so that at least part of the gripping assemblies 40 can enter the cavity of the workpiece 1, thereby gripping the workpiece 1.

Further, the second direction is perpendicular to the first direction, so that the grasping assembly 40 can approach or move away from the workpiece 1 on the shortest path.

As shown in fig. 5 and 6, the turnover device further includes an inner support assembly 60. The inner support assembly 60 can be at least partially received in a cavity of the workpiece 1. The at least part of the inner support member 60 received in the cavity of the workpiece 1 is capable of expanding to support the inner wall of the workpiece 1. In this embodiment, the cavity capacity of the workpiece 1 is relatively small, and only a part of the inner support assembly 60 is accommodated in the cavity of the workpiece 1. Which components are received in the cavities of the workpiece 1, as will be described in more detail below. In other embodiments, if the cavity capacity of the workpiece 1 is relatively large, the inner support member 60 may be completely accommodated in the cavity of the workpiece 1.

After the conveying assembly 20 conveys the workpiece 1 away from the conveying line 10, the overturning assembly 30 brings the clamping assembly 40 and the inner supporting assembly 60 close to the conveying assembly 20, so that the clamping assembly 40 grabs the workpiece 1 and at least part of the inner supporting assembly 60 enters the cavity of the workpiece 1. After the grasping assembly 40 grasps the workpiece 1, the turning assembly 30 brings the grasping assembly 40 and the inner support assembly 60 away from the carrying assembly 20 and rotates the grasping assembly 40 by a predetermined angle. The inner support member 60 is enlarged in size at least partially to support the inner wall of the workpiece 1. The propping step may also be completed before the rotating step.

Through setting up internal stay subassembly 60, on the one hand, can be so that work piece 1 is more stable on upset subassembly 30, and on the other hand, work piece 1 is propped open the back, and in the follow-up operation, after the manipulator snatched work piece 1 from upset subassembly 30, can cancel the step of breaking off work piece 1 off with the fingers and thumb, directly cover work piece 1 and locate a plurality of electric cores of piling up on to the work efficiency of manipulator has been improved.

Fig. 8 is a bottom view of an embodiment of the flipping mechanism of the present application, with the handling assembly omitted. As shown in fig. 8, the inner supporting member 60 may include a movable member 61, a supporting member 62, a sixth driver 63, and a connecting rod 64. The movable member 61 is movably connected to the flipping seat 34 and can reciprocate in the second direction and the direction opposite to the second direction. The propping piece 62 is movably connected to the turnover seat 34 and can reciprocate in the fourth direction and the opposite direction of the fourth direction for propping against the inner wall of the workpiece 1. The second direction intersects the fourth direction. The sixth driver 63 is used for driving the movable member 61 to move. The sixth driver 63 may be an air cylinder. The two ends of the connecting rod 64 are respectively rotatably connected with the movable member 61 and the support member 62 to convert the movement of the movable member 61 into the movement of the support member 62.

When the turnover assembly 30 drives the inner support assembly 60 to approach the carrying assembly 20, a portion of the movable member 61, the support member 62 and the connecting rod 64 in the inner support assembly 60 enter the cavity of the workpiece 1, and the sixth driver 63 is located outside the cavity of the workpiece 1.

The sixth driver 63 is actuated to drive the supporting member 62 to move so as to support the inner wall of the workpiece 1. Therefore, the propping action of the inner propping assembly 60 is realized through the connecting rod structure. When the inner supporting component 60 is switched between the supporting state and the non-supporting state, the action is simple. In addition, only a part of the supporting force received by the supporting member 62 is transmitted to the sixth driver 63, so that the service life of the sixth driver 63 can be prolonged.

Further, the number of the abutting pieces 62 is at least one pair. The pair of supporting members 62 are disposed at intervals in the fourth direction or the opposite direction of the fourth direction, and are respectively located at two sides of the movable member 61. The number of the supporting members 62 is ten pairs in the present embodiment. Ten pairs of the abutting pieces 62 are arranged at intervals in the second direction. The connecting rods 64 are equal in number and correspond to the supporting pieces 62 one by one.

When the movable member 61 is operated, the abutting members 62 on both sides thereof are simultaneously operated to expand or contract, thereby simultaneously abutting against the inner wall surfaces of both side walls of the workpiece 1.

In order to prevent the abutting member 62 from scratching the inner wall surface of the workpiece 1 when abutting against the workpiece 1, the abutting member 62 includes a moving body 621 and a roller 622. The moving body 621 is movably connected to the inverting seat 34 and can reciprocate in the fourth direction and the opposite direction of the fourth direction. The roller 622 is rotatably connected to the moving body 621 for abutting against the inner wall of the workpiece 1.

In order to increase the speed of switching the inner supporting member 60 between the supporting state and the non-supporting state, in the present embodiment, the second direction is perpendicular to the fourth direction.

The extreme position of movement of moveable member 61 determines the maximum dimension of extension or minimum dimension of retraction of inner support member 60. To limit the extreme position of movement of the moveable member 61, the inner support member 60 further includes a limiting member 65. The limiting member 65 is disposed on the flipping base 34 and located on a moving path of the movable member 61, and is configured to abut against the movable member 61. In order to adjust the position of the limiting member 65, the limiting member 65 can be detachably connected to the flipping base 34.

The carrier body 21 is movably attached to the second mount 25, and is capable of reciprocating in a third direction and a direction opposite to the third direction, for carrying the workpiece 1. In this embodiment, the third direction is the same as the first direction. The fourth driver 22 is used for driving the conveying main body 21 to move so as to convey the workpiece 1 on the conveying main body 21 away from the conveying line 10. The fourth driver 22 may be a cylinder. The carrying surface of the carrying body 21 is lower than the carrying surface of the transmission line 10.

When the workpiece 1 is conveyed to a predetermined station, the workpiece 1 is positioned right above the carrying surface of the carrying body 21. At this time, the fourth driver 22 drives the conveying body 21 to move in the third direction, so as to separate the workpiece 1 from the conveying line 10, and separate the workpiece 1 from the conveying line 10, thereby facilitating the gripping unit 40 to grip the workpiece 1. After the gripping member 40 grips the workpiece 1, the fourth driver 22 drives the carrying main body 21 to be reset.

Further, the handling assembly 20 comprises at least one pair of gripping members 23 and a fifth drive 24. The fifth driver 24 is used to drive the pair of gripping members 23 to move relatively to grip or release the workpiece 1 on the carrier main body 21. The fifth actuator 24 may be a pneumatic cylinder. The clamping member 23 may be fixedly disposed at the driving end of the fifth driver 24.

After the workpiece 1 is conveyed to the predetermined station: the fifth driver 24 drives the pair of clamp pieces 23 to clamp the workpiece 1. The fourth driver 22 drives the conveyance body 21 to move in the third direction, and separates the workpiece 1 from the conveyance line 10. The order of the two steps may also be reversed. After the gripping assembly 40 grips the workpiece 1, the fifth driver 24 drives the pair of gripping members 23 to release the workpiece 1. The fourth driver 22 drives the carrier body 21 to return.

The workpiece 1 is clamped by the pair of clamping pieces 23, so that the workpiece 1 can be fixed and accurate in position on the carrying main body 21, and the clamping assembly 40 can accurately grab the workpiece 1.

The working process of the turnover device is as follows:
