Referring to fig. 1, the present invention provides a battery cell clamping fixture 100. In addition, the invention also provides a battery cell processing device. The battery cell processing device includes a plurality of battery cell clamping jigs 100 and a circulating conveying mechanism.

Each of the cell clamping jigs 100 is capable of positioning and clamping a cell 20 to be processed, and the two ends of the cell 20 have tabs 21. The conveying route of the circulating conveying mechanism is annular, a feeding station, an operating station and a discharging station are arranged along the conveying route of the circulating conveying mechanism, and the plurality of battery cell clamping fixtures 100 can sequentially pass through the feeding station, the operating station and the discharging station under the driving of the circulating conveying mechanism.

The feeding station is provided with a feeding mechanism (not shown), and the cell clamping jig 100 together with the clamped cell 20 can be placed into the circulating conveying mechanism; the operation station is correspondingly provided with a welding mechanism, a cutting mechanism and the like, so that the tab 21 of the battery cell 20 can be cut, welded and the like; at the blanking station, the finished battery cell 20 may be taken away from the battery cell clamping jig 100 by using a manipulator or a manual blanking method. Finally, the cell clamping jig 100 may return to the loading station again and cycle accordingly.

Referring to fig. 5 and fig. 6, in the present embodiment, the circulating conveying mechanism includes a circulating line 210 and a plurality of jig bottom plates 220 slidably disposed on the circulating line 210, and the plurality of cell clamping jigs 100 can be respectively disposed on the plurality of jig bottom plates 220.

Specifically, the jig base plate 220 may be connected to the circulation line 210 through a sliding block and a guide rail, the circulation line 210 generally includes a plurality of conveying lines 211 and a power element 212, and the power element 212 can drive the jig base plate 220 to move along the conveying path of the circulation conveying mechanism. Through the transition of tool bottom plate 220, can conveniently carry out getting of tight tool 100 of electric core clamp and put. For example, the conveying line 210 in the present embodiment includes two conveying lines 211 arranged above and below each other and four power elements 212. Two power elements 212 are arranged on the left side and the right side to drive the jig base plate 220 to transfer between the upper conveying line 211 and the lower conveying line 211; the upper and lower power elements 212 are used for driving the jig base plate 220 to horizontally move on the corresponding conveying lines 211.

In addition, after many cycles, the cell clamping jig 100 may be damaged. Therefore, in the present embodiment, the battery cell processing apparatus is further provided with a replacement station, and the battery cell clamping jig 100 moved to the replacement station can be removed from the jig base plate 220. The replacement station is typically located downstream of the blanking station and may be co-located with the blanking station. After the damaged battery cell clamping jig 100 is removed, the empty jig base plate 220 may be supplemented with a new battery cell clamping jig 100 when entering the loading station. Therefore, the whole-line shutdown processing can be avoided when the individual cell clamping jig 100 is abnormal, so that the capacity is not affected.

In this embodiment, the head end and the tail end of each jig base plate 220 are respectively provided with a hooking part 221 and a fastening part 222, and the plurality of jig base plates 220 are hooked with the fastening part 222 through the hooking parts 221 to realize head-to-tail connection. Thus, the jig base plates 220 can be driven by each other, so that the circulating line 210 can drive the jig base plates 220 to move simultaneously by only arranging a small number of power elements 212, thereby facilitating the simplification of the structure.

Further, in this embodiment, the hooking element 221 includes two cam bearings 2211 spaced apart along the width direction of the jig base plate 220, the fastening element 222 includes two L-shaped baffles 2221 spaced apart along the width direction of the jig base plate 220, the two L-shaped baffles 2221 are enclosed to form a slot 2223 having an opening 2222, and a distance between the two cam bearings 2211 is smaller than a width of the slot 2223 and larger than a width of the opening 2222.

The width direction refers to a direction perpendicular to the moving direction of the jig base plate 220, i.e., the vertical direction shown in fig. 6. When the hook 221 and the fastener 222 are in the unhooking state, the two adjacent jig base plates 220 move relatively in a direction perpendicular to the bearing surface of the jig base plate 220 (a direction perpendicular to the plane of the drawing shown in fig. 6), so that the cam bearing 2211 enters the slot 2223 and cannot be disengaged from the fastener 2222, thereby achieving hooking. When the hooking element 221 and the locking element 222 are in a hooked state, the two adjacent jig base plates 220 move relatively in a direction perpendicular to the bearing surface of the jig base plate 220, so that the cam bearing 2211 can be moved out of the slot 2223, thereby achieving unhooking. It can be seen that the above structure facilitates the hook 221 and the latch 222 to be unhooked or hooked.

Referring to fig. 2 to fig. 4, the cell clamping fixture 100 includes a base 110 and a pressing mechanism 120. The base 110 is provided with a cell cushion block 111 and tab supporting blocks 112, the cell cushion block 111 is used for bearing the cell 20, and the tab supporting blocks 112 are located at two ends of the cell 20 cushion block 111 and are used for bearing tabs 21 at two ends of the cell 20. Both the cell cushion block 111 and the tab support block 112 may be plate-shaped structures, and the tab support block 112 extends outward from the end of the cell cushion block 111.

The pressing mechanism 120 includes a pressing driving member 121, a cell pressing block 122 and a pressing roller 123, the cell pressing block 122 and the pressing roller 123 are both disposed at the driving end of the pressing driving member 121, and the pressing roller 123 can rotate. Under the driving of the pressing driving member 121, the cell pressing block 122 and the pressing roller 123 can be pressed down along a preset direction. Specifically, the preset direction refers to the up-down direction shown in fig. 1. The pressing driving member 121 may be a spring return cylinder, and has a driving shaft 1211, and the driving shaft 1211 is extended and retracted to drive the cell pressing block 122 and the pressing roller 123 to press down.

When the cell pressing block 122 and the pressing roller 123 are pressed down, the cell pressing block 122 can press the cell 20 located in the cell cushion block 111, and the pressing roller 123 can press and hold the tabs 21 at the two ends of the cell 20 in the tab supporting block 112. Under the pressing action of the cell pressing block 122, the main body portion of the battery 20 can be well positioned. In the process of compressing the battery cell 20 by the cell pressing block 122, the pressing roller 123 abuts against the tabs 21 at the two ends of the battery cell 20 and pushes the tabs to the tab support block 112. Since the pressing roller 123 can rotate, the pressing roller 123 rolls along the surface of the tab 21 in the process of pushing the tab 21 downward.

The rotation axis of the pressing roller 123 is substantially parallel to the bearing surface of the tab holder 112. In the process of pressing by the pressing roller 123, the tab 21 can be smoothed by the rolling action without pulling the tab 21, so that the tab 21 is not easily wrinkled. It can be seen that, after the battery cell 20 is compressed, the tabs 21 at the two ends of the battery cell are effectively limited, so that the battery cell clamping jig 100 can better position the battery cell 20 and the tabs 21 at the two ends of the battery cell. Moreover, the consistency of the tab 21 is good after smoothing by the press roller 123, so that the subsequent processing precision of the tab 21 is high.

Specifically, in the present embodiment, there are two pressing mechanisms 120 respectively located at two ends of the base 110. The two pressing mechanisms 120 can press and hold the two ends of the battery cell 20 together, and the pressing effect is good. Moreover, the two pressing mechanisms 120 can respectively press the tabs 21 at the two ends of the battery cell 20. Obviously, in other embodiments, only one hold-down mechanism 120 may be provided. At this time, the cell pressing block 122 needs to be long enough, and two pressing rollers 123 need to be disposed at two ends of the cell pressing block 122, so as to respectively press the tabs 21 at two ends of the cell 20.

In this embodiment, the pressing mechanism 120 further includes an adapter plate 124 and a connecting rod 125, the adapter plate 124 is fixed to the driving end of the pressing driving member 121, the cell pressing block 122 is installed on the adapter plate 124, one end of the connecting rod 125 is fixed to the adapter plate 124, and the pressing roller 123 is installed on one end of the connecting rod 125 far away from the connecting plate 124 through a bearing 126.

Specifically, the adapter plate 124 and the connecting rod 125 perform the functions of adapter and transition, so as to facilitate the connection between the cell pressing block 122 and the driving end of the pressing driving member 121 and the pressing roller 123. Each pressing mechanism 120 is provided with at least two connecting rods 125, and both ends of the pressing roller 123 are respectively mounted to the two connecting rods 125 through bearings 126, thereby achieving rotation.

In this embodiment, the cell pressing block 122 may be elastically pressed against the cell located in the cell cushion block 111. Thus, when the cell pressing block 122 presses the cell 20, the cell 20 can be prevented from being damaged due to an excessive pressure applied by the pressing driving member 120.

Specifically, an elastic mechanism 127 may be disposed between the adapter plate 124 and the cell pressing block 122, so that the cell pressing block 122 can elastically press and hold the cell located in the cell cushion block 111. The resilient mechanism 127 may be a resilient pad, a compression spring, or the like.

In this embodiment, the base 110 is fixedly provided with a limiting member 113, and the pressing driving member 121 can drive the adaptor plate 124 to press down to abut against the limiting member 113. The limiting member 113 may be a screw or the like, and the pressing distance between the cell pressing block 122 and the pressing roller 123 is limited by the limiting member 113. When the adapter plate 124 abuts against the stopper 113, the pressing roller 123 stops pressing down, so that the consistency of pressing down the tabs 21 on both sides can be ensured.

In this embodiment, the pressing mechanism 120 can be switched between a first state and a second state, and when in the first state, projections of the cell pressing block 122 and the pressing roll 123 along a preset direction are respectively located in the ranges of the cell cushion block 111 and the tab support block 112; when the battery cell is in the second state, projections of the battery cell pressing block 122 and the pressing roller 123 along the preset direction are respectively located outside the ranges of the battery cell cushion block 111 and the tab supporting block 112.

As shown in fig. 2, the hold-down mechanism 120 is in a first state. At this time, the cell pressing block 122 and the pressing roller 123 are respectively located above the cell cushion block 111 and the tab holding block 112. Therefore, when the pressing driving member 121 drives the cell pressing block 122 and the pressing roller 123 to press down, the cell 20 and the tab 21 can be pressed tightly.

When the adapter plate 124 shown in fig. 2 rotates 90 degrees counterclockwise or clockwise, the cell pressing block 122 and the pressing roller 123 are removed from above the cell cushion block 111 and the tab holding block 112, and the pressing mechanism 120 is switched to the second state. At this time, the pressing mechanism 120 will not shield the tops of the cell cushion block 111 and the tab support block 112, so as to conveniently take and place the cell 20.

Further, in the present embodiment, the pressing driving member 121 includes a driving shaft 1211, and the driving shaft 1211 extends along a predetermined direction and can rotate around an axis parallel to the predetermined direction to drive the pressing mechanism 120 to switch between the first state and the second state. Therefore, when the state of the pressing mechanism 120 needs to be switched, it is only necessary to rotate the drive shaft 1211, and thus the operation can be facilitated.

Referring to fig. 7, the battery cell processing apparatus further includes a clip opening mechanism 300, and the clip opening mechanism 300 is disposed at the feeding station and the discharging station. When the electrical core clamping jig 100 enters the feeding station and the discharging station, the opening and clamping mechanism 300 can switch the pressing mechanism 120 to the second state, so that the electrical core 20 is conveniently subjected to feeding and discharging operations.

More specifically, the clip opening mechanism 300 includes a supporting plate 310, a rotating shaft 320, a lifting driving member 330, and a rotating driving member (not shown). The rotating shaft 320 extends along a predetermined direction and is rotatably mounted on the supporting plate 310, and the rotating shaft 320 can be lifted along the predetermined direction. The elevating driving member 330 is installed on the supporting plate 310 and can drive the shaft 320 to be lifted until the top end of the shaft 320 abuts against the driving shaft 1211. The top end of the shaft 320 may be configured as a sleeve to provide a snug fit with the drive shaft 1211. The rotary driving member can drive the rotating shaft 320 to rotate and drive the driving shaft 1211 to rotate, so as to switch the pressing mechanism 120 between the first state and the second state.

The lift driving unit 330 may employ an air cylinder. Correspondingly, two rotating shafts 320 are provided, and the two pressing mechanisms 120 are respectively subjected to the unclamping operation. The clip opening mechanism 300 further includes a connecting plate 350, and the two rotating shafts 320 are rotatably mounted to the connecting plate 350 through the bearing 340. The driving end of the lifting driving member 330 abuts against the connecting plate 350, so that the two rotating shafts 320 can be driven to lift up at the same time.

Therefore, after the cell clamping jig 100 is in place, the opening mechanism 300 is operated to automatically switch the pressing mechanism 120 to the second state for picking and placing the cell 20. After the picking and placing are completed, the opening and clamping mechanism 300 reversely acts to switch the pressing mechanism 120 to the first state to prepare for pressing the battery cell 20, so that the efficiency can be improved.

In the cell clamping jig 100 and the cell processing apparatus, the cell 20 to be processed may be placed in the cell cushion block 111 first. Then, the pressing driving part 121 drives the cell pressing block 122 and the pressing roller 123 to press down along the preset direction until the cell pressing block 122 presses the cell 20 against the cell cushion block 111 to realize positioning. At the same time, the pressing roller 123 abuts against the tabs 21 at both ends of the battery cell 20 and pushes the tabs 21 toward the tab receiving block 112. Since the pressing roller 123 is rotatable, the pressing roller 123 rolls along the surface of the tab 21 while pushing the tab 21 downward, so that the tab 21 is smoothed out and the tab 21 is not pulled. So, after electric core 20 was compressed tightly, its both ends utmost point ear 21 will also be spacing effectively, and utmost point ear 21's uniformity is better. Therefore, the battery cell clamping jig 100 and the battery cell processing device can improve the processing accuracy.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that various changes and modifications can be made by those skilled in the art without departing from the spirit of the invention, and these changes and modifications are all within the scope of the invention.
