It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0035] In order to solve the technical problem that battery cells are generally placed on a tray made of foam plastic, and there is a risk of lifting the tray when a robot grabs the battery cells, which is not conducive to the implementation of subsequent processes, the utility model provides a battery cell grabbing device, which can effectively separate the battery cells from the tray to avoid adverse effects on subsequent processes, and the pressing mechanism does not interfere with the clamping mechanism clamping the battery cells, ensuring that the clamping mechanism can quickly clamp the battery cells, and the utility model has a simple structure and saves costs.

[0036] It should be noted that the battery cell grasping device described in the present invention is used for but not limited to power battery production lines, etc. For the convenience of explanation, in the present invention, only the battery cell grasping device applied to a power battery production line is used as an example for explanation, and the principle of applying the battery cell grasping device to other types of equipment is essentially the same as the principle applied to the power battery production line, which will not be repeated here.

[0037] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 It is a structural schematic diagram of a battery cell grabbing device in an embodiment of the utility model, the battery cell grabbing device includes a mounting seat 1, a moving mechanism 2, a clamping mechanism 3 and a pressing mechanism 4; the moving mechanism 2 is connected to the mounting seat 1 to drive the mounting seat 1 to move; the clamping mechanism 3 is installed on the mounting seat 1 to clamp the material (battery cell); the pressing mechanism 4 includes an elastic member 41 and a pressing plate 42, the pressing plate 42 is connected to the mounting seat 1 via the elastic member 41, and when the mounting seat 1 moves close to the material, the pressing plate 42 can elastically press against a carrier (tray) for loading the material and squeeze the elastic member 41 until the mounting seat 1 drives the clamping mechanism 3 for clamping the material to move away from the carrier until the material is separated from the carrier.

[0038] In the battery cell grabbing device provided by the utility model, the moving mechanism 2 drives the mounting seat 1 to move. When the mounting seat 1 is close to the battery cell, the clamping mechanism 3 can clamp the battery cell. At this time, the pressing plate 42 also elastically presses against the tray for loading the battery cell, and squeezes and contracts the elastic member 41. Then, the mounting seat 1 is driven to gradually move away from the tray by the moving mechanism 2. In the process of the mounting seat 1 driving the clamping mechanism 3 away from the tray, the elastic member 41 gradually releases the elastic potential energy, so that the pressing plate 42 is still in a state of elastically pressing against the tray until the battery cell is completely separated from the tray. In this way, this solution can effectively separate the battery cell from the tray while transporting the battery cell, avoiding adverse effects on subsequent processes, and the pressing mechanism 4 does not interfere with the clamping mechanism 3 clamping the battery cell, ensuring that the clamping mechanism 3 can quickly clamp the battery cell, and the structure is simple and the cost is low.

[0039] In one embodiment, see Figure 3 and Figure 4 The pressing mechanism 4 also includes a connecting plate 43 and a guide rod 44. The connecting plate 43 is connected to the mounting seat 1 and is provided with a guide channel 43a toward the moving direction of the pressing plate 42; one end of the guide rod 44 is movably inserted into the guide channel 43a, and the other end is connected to the pressing plate 42. The elastic member 41 is a compression spring 411, which is sleeved on the guide rod 44 and connected to the connecting plate 43 and the pressing plate 42.

[0040] In this embodiment, when the pressing plate 42 initially presses against the tray, the clamping mechanism 3 has not yet contacted the battery cell. At this time, the mounting seat 1 continues to move closer to the tray until the clamping mechanism 3 contacts the battery cell. When the clamping mechanism 3 contacts the battery cell, the pressing plate 42 squeezes the compression spring 411, that is, the pressing plate 42 elastically presses against the tray. After the clamping mechanism 3 clamps the battery cell, the mounting seat 1 drives the clamping mechanism 3 away from the tray. Since the pressing plate 42 is still elastically pressed against the tray, when the mounting seat 1 drives the clamping mechanism 3 away, the pressing plate 42 can push the tray and the battery cell to separate.

[0041] In one embodiment, a plurality of guide channels 43 a are provided, and the plurality of guide channels 43 a are spaced apart along the radial direction thereof. A plurality of guide rods 44 and compression springs 411 are provided corresponding to the guide channels 43 a.

[0043] In one embodiment, see Figure 5The pressing plate 42 includes a pressing plate 421 and a sliding plate 422 connected at an angle, the pressing plate 421 is used to elastically press against the carrier, one of the sliding plate 422 and the mounting seat 1 is provided with a sliding rail 11, and the other corresponding to the sliding rail 11 is provided with a sliding groove 422a, the sliding rail 11 and the sliding groove 422a are extended along the movable direction of the pressing plate 42; wherein, the guide rod 44 and the compression spring 411 are connected to the sliding plate 422.

[0044] In this embodiment, the slide rail 11 can cooperate with the slide groove 422a to make the pressing plate 42 move along a predetermined track to avoid the pressing plate 42 from being misaligned when pressing against the tray. Specifically, in this solution, the slide rail 11 is arranged on the mounting seat 1, and the slide groove 422a is formed on the sliding plate 422.

[0045] In one embodiment, the mounting seat 1 includes a main seat 12, a movable seat 13 and a driving unit 14. The movable seat 13 is mounted on the main seat 12 and can move along the moving direction of the pressing plate 42. The driving unit 14 is mounted on the main seat 12 and is drivingly connected to the movable seat 13, and is used to drive the movable seat 13 to move along the moving direction of the pressing plate 42; the clamping mechanism 3 is mounted on the main seat 12, and the elastic member 41 connects the movable seat 13 and the pressing plate 42.

[0046] In this embodiment, the driving unit 14 drives the movable seat 13 to move along the moving direction of the pressing plate 42, so that when the battery cells are stacked, the pressing plate 42 can be moved to the side of the mounting seat 1 away from the clamping mechanism 3 by adjusting the position of the movable seat 13, so as to avoid interference of the pressing mechanism 4 with the stacked battery cells. Specifically, in this solution, the driving unit 14 is a slide cylinder 141, and the slide 142 of the slide cylinder 141 is movably arranged along the moving direction of the pressing plate 42, and its driving seat 143 is installed on the main body seat 12, and the movable seat 13 is installed on the slide 142. That is, the position adjustment of the movable seat 13 is achieved by the slide cylinder 141, and the drive is stable and reliable. It should be noted that the structure and principle of the slide cylinder 141 are prior art and will not be elaborated here.

[0047] In one embodiment, a portion of the pressing plate 42 extends toward the driving seat 143 , and a relief opening 421 a is disposed corresponding to the driving seat 143 .

[0048] In this embodiment, an avoidance opening 421a is provided on the pressing plate 42 corresponding to the driving seat 143, so that when the movable seat 13 drives the pressing plate 42 to move toward the side of the mounting seat 1 away from the clamping mechanism 3, the driving seat 143 can pass through the avoidance opening 421a, thereby avoiding interference between the pressing plate 42 and the driving seat 143 and making the overall device more compact.

[0049] In one embodiment, there are multiple groups of clamping mechanisms 3, and the multiple groups of clamping mechanisms 3 are arranged at intervals on the same side of the mounting seat 1; there are multiple groups of pressing mechanisms 4, and the multiple pressing mechanisms 4 are arranged at intervals.

[0050] In this embodiment, multiple sets of clamping mechanisms 3 and multiple sets of pressing mechanisms 4 are provided to improve the efficiency and ability of the device to transport the battery cells, while effectively ensuring that the battery cells are separated from the tray. Specifically, in this solution, four sets of clamping mechanisms 3 are provided, and two sets of pressing mechanisms 4 are provided.

[0051] In one embodiment, the moving mechanism 2 is a mechanical arm 21, and the mounting base 1 is mounted on the arm execution end of the mechanical arm 21; Figure 6 The clamping mechanism 3 includes two clamping motors 31 and two clamping plates 32. The two clamping motors 31 are installed at the same side of the mounting base 1 at intervals, and respectively drive the two clamping plates 32 to drive the two clamping plates 32 to move closer to and away from each other.

[0052] In this embodiment, the moving mechanism 2 is set in the form of a mechanical arm 21, which can realize the multi-degree-of-freedom movement of the mounting base 1 through the mechanical arm 21, thereby improving the practicality of the device. At the same time, two clamping motors 31 are used to drive the two clamping plates 32 to move closer to and away from each other, so as to achieve the clamping and loosening of the battery cell, and the structure is simple and reliable. The two clamping plates 32 of the clamping mechanism 3 can rotate synchronously.

[0053] In addition, the utility model also provides a power battery production line, which includes a cell grabbing device as described in any one of the above. It should be noted that the detailed structure of the cell grabbing device of the power battery production line can refer to the above-mentioned embodiment of the cell grabbing device, which will not be repeated here; since the above-mentioned cell grabbing device is used in the power battery production line of the utility model, the embodiment of the power battery production line of the utility model includes all technical solutions of all embodiments of the above-mentioned cell grabbing device, and the technical effects achieved are also exactly the same, which will not be repeated here.

[0054] In order to better understand the present invention, the following Figures 1 to 6 The technical solution of the utility model is described in detail:

[0055] When the robot arm 21 drives the mounting seat 1 to move closer to the battery cell, the pressing plate 42 first contacts the tray, that is, when the pressing plate 42 initially presses against the tray, the clamping mechanism 3 has not yet contacted the battery cell. Then, the robot arm 21 continues to drive the mounting seat 1 closer to the tray until the clamping mechanism 3 contacts the battery cell. When the clamping mechanism 3 contacts the battery cell, the pressing plate 42 squeezes the compression spring 411, that is, the pressing plate 42 elastically presses against the tray at this time. After the clamping mechanism 3 clamps the battery cell, the robot arm 21 drives the mounting seat 1 and the clamping mechanism 3 away from the tray. During this process, the compression spring 411 releases its elastic potential energy, so that the pressing plate 42 still elastically presses against the tray, so that when the robot arm 21 drives the clamping mechanism 3 away, the pressing plate 42 can push the tray and the battery cell to separate.
