In order to make the technical problems, technical solutions and advantageous effects solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the present invention, the directions of the relevant parts and structures, such as "front", "rear", "left", "right", "upper", "lower", and the like, are all directions with reference to the normal placement of the automobile.

As shown in fig. 1 to 3, in an embodiment, the strapping apparatus 100 includes: a table 10, a platen assembly 20, a first drive assembly 30, and a second drive assembly 40. A storage area 101 for placing the battery cell 200 is arranged on the workbench 10, and an accommodating space 201 for installing a bundling ring is arranged on the pressing plate assembly 20; the first driving assembly 30 is mounted on the workbench 10, the first driving assembly 30 is connected with the platen assembly 20, and is used for driving the platen assembly 20 to clamp the battery cells 200 placed in the storage region 101; the second driving assembly 40 is mounted on the workbench 10, and the second driving assembly 40 is connected to the pressing plate assembly 20 and is configured to drive the pressing plate assembly 20 to move, so that the accommodating space 201 can drive the bundling ring to be close to the storage area 101, so as to trap the bundling ring 300 on the battery cell 200 clamped by the pressing plate assembly 20. The bundling ring 300 is bundled on the battery cell 200 clamped by the pressing plate assembly 20, which means that the bundling ring 300 is actually sleeved on the battery cell 200 clamped by the pressing plate assembly 20.

In practical production, the bundling ring 300 mainly uses a steel ring, and since the steel ring is directly sleeved on the outer side of the battery cell 200, the steel ring can be made of a steel belt in advance, so that the production efficiency can be improved. In addition, in the prior art, firstly, the steel band is wound outside the battery cell 200, and then the two ends of the steel band are fixed together to form the steel ring, under the condition, in order to avoid damaging the battery cell 200, the two ends of the steel band are usually connected in a riveting mode, and when the subsequent battery pack is applied to an automobile, the subsequent battery pack is in a vibration state for a long time, so that the riveting part of the steel ring is easily broken. After the scheme is adopted, the steel ring can be manufactured in advance, so that the two ends of the steel belt can be fixed together to form the steel ring by adopting a connection mode with higher reliability such as welding and the like.

It can be understood that, in the actual use process, the plurality of battery cells 200 are usually fixed together by using the bundling ring 300, at this time, the two pressing plates squeeze the plurality of battery cells 200 placed in the storage area 101 together, and in this embodiment, the bundling ring 300 is sleeved on the battery cells, or one bundling ring 300 is sleeved on the outer sides of the plurality of battery cells, that is, the plurality of battery cells are located in the hollow portion of one bundling ring at the same time. For example, after the four battery cells 200 are pressed together, a bundling ring 300 may be used to bundle and fix the four battery cells 200 together.

As shown in fig. 1 to 3, the pressing plate assembly 20 includes a first pressing plate 1 and a second pressing plate 2, the first pressing plate 1 and the second pressing plate 2 being respectively disposed at left and right sides of the storage area 101; the right surface 11 of the first pressing plate 1 is provided with a first groove 12, the left surface 21 of the second pressing plate 2 is provided with a second groove 22, and the first groove 12 and the second groove 22 are spaced and opposite to each other to form an accommodating space 201, wherein the right surface 11 of the first pressing plate 1 is a surface of the first pressing plate 1 opposite to the second pressing plate 2, the left surface 21 of the second pressing plate 2 is a surface of the second pressing plate 2 opposite to the first pressing plate 1, and the accommodating space 201 is formed between the first pressing plate 1 and the second pressing plate 2.

The work of two electric jar can be controlled through controllers such as PLC, and the during operation can control two electric jar synchronous motion in order to drive the bracing piece up-and-down motion. The first connection unit 9a includes a first slider mounted on the guide rail, and the first presser plate 1 is mounted on the first slider. The first sliding block is matched with the guide rail and can slide left and right along the guide rail, so that the first pressing plate 1 can slide left and right. The second connection unit 9b includes a second slider so that the second slider is mounted on the guide rail and the second presser plate 2 is mounted on the second slider. The second sliding block is matched with the guide rail and can slide left and right along the guide rail, so that the second pressing plate 2 can slide left and right. In order to realize that the second connecting unit can be arranged at different positions of the supporting unit, the second connecting unit is further provided with a bolt, the second sliding block is provided with a thread through hole, the bolt can be in thread fit with the thread through hole and is abutted against the guide rail, and the second sliding block can be locked on the guide rail. During the use, the user can adjust the position of second slider on the guide rail according to actual need, and then realizes the adjustment to the biggest interval between two clamp plates for equipment 100 can extrude and tie up different quantity of electric core 200.

Of course, in other embodiments, the power unit 7 may be provided with only one electric cylinder. The supporting unit 8 may be only a supporting rod, and the supporting rod itself can be used as a guiding rod, and the first slider and the second slider are sleeved on the supporting rod and can slide along the supporting rod.
