Description

Technical Field

[0001] The utility model relates to the field of battery cell module processing equipment. Background Art

[0002] At present, during the battery cell processing, battery cells are usually arranged in two rows to form a double-row module, as Figure 1 , 2 shown. Glue needs to be applied between adjacent battery cells to ensure stable bonding between adjacent battery cells. After the staff finishes arranging the battery cells after glue application, in order to accelerate the curing of the glue and the stability after curing, the double-row module usually needs to be heated. The heating effect of the traditional heating mechanism on the double-row module is not good, and there is also a certain probability that the battery cells will shift in position after heating, resulting in a high scrap rate. In addition, considering that there are two common specifications, long and short, for the double-row module, the traditional heating mechanism is not yet applicable to the heating of the two different specifications of double-row modules.

[0006] As Figure 4 , 5As shown, the pitch-changing mechanism 24 includes a pitch-changing cylinder 240, a head slide plate 241, an intermediate slide plate 242, a tail-end slide plate 243, and a pair of C-shaped linkage pitch-changing blocks 244 arranged in pairs.

[0007] Two of a pair of linkage pitch-changing blocks 244 are respectively fixedly connected to the head slide plate 241, the intermediate slide plate 242, or the tail-end slide plate 243 on both sides thereof. The two linkage pitch-changing blocks 244 are arranged vertically opposite to each other, and the end of one linkage pitch-changing block extends into the middle recess of the other linkage pitch-changing block.

[0008] A set of downward pressure pole blocks 23 are installed on each intermediate slide plate 242 and the tail-end slide plate 243, and multiple sets of downward pressure pole blocks 23 evenly distributed along the top cross beam 22 are installed on the head slide plate 241.

[0009] Four downward pressure pole blocks 23 are a set. The downward pressure pole blocks 23 are connected to the head slide plate 241, the intermediate slide plate 242, or the tail-end slide plate 243 through L-shaped cantilevers 231 and guide rods 232. The top end of the L-shaped cantilever 231 is fixedly connected to the head slide plate 241, the intermediate slide plate 242, or the tail-end slide plate 243. The guide rod 232 is fixedly connected to the top end of the downward pressure pole block 23 and penetrates through the L-shaped cantilever 231. A limit block 233 located above the L-shaped cantilever 231 is fixedly connected to the top end of the guide rod 232.

[0027] To clearly illustrate the technical features of this patent, the following will elaborate on this patent in detail through specific embodiments and in conjunction with its accompanying drawings.

[0028] The overall structure of this case is as Figure 3 shown, including a workbench 1 and a pole column pressing-down assembly 2. There is a heating station on the workbench 1 for accommodating and heating a double-row module; the pole column pressing-down assembly 2 is movably installed on the workbench 1. The pole column pressing-down assembly 2 includes an installation frame 21, a traveling mechanism, a top cross beam 22, a lifting mechanism, several groups of pressing-down pole column blocks 23, and a pitch-changing mechanism 24. The installation frame 21 is movably installed on the workbench 1 through the traveling mechanism. The top cross beam 22 is movably installed on the installation frame 21 through the lifting mechanism. Each group of pressing-down pole column blocks 23 is connected to the top cross beam 22 and is driven by the pitch-changing mechanism to translate the pressing-down pole column blocks 23 along the top cross beam 22, thereby adjusting the distance between several groups of pressing-down pole column blocks 23.

[0029] As Figure 4 、 5As shown, the pitch-changing mechanism 24 includes a pitch-changing cylinder 240, a head slide plate 241, an intermediate slide plate 242, a tail-end slide plate 243, and a pair of C-shaped linkage pitch-changing blocks 244 arranged in pairs. The head slide plate 241, the intermediate slide plate 242, and the tail-end slide plate 243 are arranged in sequence on the top crossbeam 22. Among them, the head slide plate 241 and the intermediate slide plate 242 are slidably connected to the top crossbeam 22, and the tail-end slide plate 243 is fixedly connected to the top crossbeam 22. The cylinder block of the pitch-changing cylinder 240 is fixedly connected to the top crossbeam 22, and the cylinder rod of the pitch-changing cylinder 240 is fixedly connected to the head slide plate 241. There are several intermediate slide plates 242, and adjacent intermediate slide plates 242 are connected by a pair of linkage pitch-changing blocks 244. The intermediate slide plate 242 at the first position is connected to the head slide plate 241 by a pair of linkage pitch-changing blocks 244, and the intermediate slide plate 242 at the last position is connected to the tail-end slide plate 243 by a pair of linkage pitch-changing blocks 244.

[0030] Two of a pair of linkage pitch-changing blocks 244 are respectively fixedly connected to the head slide plate 241, the intermediate slide plate 242, or the tail-end slide plate 243 on both sides thereof. The two linkage pitch-changing blocks 244 are arranged vertically opposite to each other, and the end of one linkage pitch-changing block extends into the middle recess of the other linkage pitch-changing block.

[0031] A set of downward pressing pole blocks 23 are installed on each intermediate slide plate 242 and the tail-end slide plate 243, and multiple sets of downward pressing pole blocks 23 evenly distributed along the top crossbeam 22 are installed on the head slide plate 241.

[0032] A locking mechanism for locking the position is also installed on the head slide plate 241.

[0033] Four downward pressing pole blocks 23 are in a group. The downward pressing pole blocks 23 are connected to the head slide plate 241, the intermediate slide plate 242, or the tail-end slide plate 243 through an L-shaped cantilever 231 and a guide rod 232. The top end of the L-shaped cantilever 231 is fixedly connected to the head slide plate 241, the intermediate slide plate 242, or the tail-end slide plate 243. The guide rod 232 is fixedly connected to the top end of the downward pressing pole block 23 and penetrates through the L-shaped cantilever 231. A limiting block 233 located above the L-shaped cantilever 231 is fixedly connected to the top end of the guide rod 232. A compression spring 234 is also sleeved on the guide rod 232 and abuts between the downward pressing pole block 23 and the L-shaped cantilever 231. In this way, when the crossbeam descends and presses the battery cell pole through the downward pressing pole block 23, the compression spring can ensure the downward pressure while avoiding damaging the battery cell.

[0034] Such as Figure 4 、 5As shown, when varying the distance, the tail-end slide plate 243 will be used as the fixed base. When the cylinder rod of the variable-distance cylinder 240 fully retracts, the head-end slide plate 241, the middle slide plate 242, and the tail-end slide plate 243 will be closely arranged in sequence, and multiple groups of downward pressing pole blocks 23 installed below the three will also be arranged at equal intervals. In this way, when facing Figure 1 the shown long double-row module, all the downward pressing pole blocks 23 will be as Figure 9 shown, and after descending, they will press on the pole columns of each battery cell. When facing Figure 2 the shown short double-row module, the cylinder rod of the variable-distance cylinder 240 can be controlled to extend to the limit position. At this time, each pair of linkage variable-distance blocks 244 will also be stretched to the maximum, so that the spaces between multiple middle slide plates 242 and the tail-end slide plate 243 will be equally elongated, thereby realizing variable distance. In this way, when facing the short double-row module with fewer but larger-spacing battery cells, the multiple groups of downward pressing pole blocks 23 arranged at equal intervals below the middle slide plates 242 and the tail-end slide plate 243 will press on the pole columns of each battery cell after descending.

[0035] The described traveling mechanism includes a rodless cylinder 25. A traveling slide rail perpendicular to the top cross beam 22 is fixedly installed on the workbench 1. The bottom end of the installation frame 21 is slidably installed on the traveling slide rail. The cylinder body of the rodless cylinder 25 is fixedly installed on the workbench 1 parallel to the traveling slide rail, and the output end of the rodless cylinder 25 is fixedly connected to the installation frame 21. Thus, the installation frame 21 is driven by the rodless cylinder 25 to reciprocate in a direction perpendicular to the top cross beam 22.

[0036] The described lifting mechanism includes a lifting cylinder 26. A vertically arranged lifting slide rail is fixedly installed on the installation frame 21. The end of the top cross beam 22 is slidably installed on the lifting slide rail. The cylinder body of the lifting cylinder 26 is vertically arranged and fixedly connected to the installation frame 21, and the cylinder rod of the lifting cylinder 26 is fixedly connected to the end of the top cross beam 22. Thus, the top cross beam 22 is driven by the lifting cylinder 26 to perform a lifting motion. Further, to maintain the stability of the cross beam, a pair of installation frames 21 and traveling mechanisms can be arranged on the workbench, and both ends of the top cross beam 22 are respectively slidably connected to the two installation frames 21.

[0037] As Figure 6 、 7 shown, this case also includes a side plate pressing assembly 3 and a bottom plate pressing assembly 4. Electric heating sheets are provided inside the two, and the double-row module in the heating station is clamped and heated by the two.

[0038] As Figure 6As shown, the bottom plate pressing assembly 4 is fixedly installed on the workbench 1. There are two side plate pressing assemblies 3, and the two side plate pressing assemblies 3 are respectively slidably installed on the workbench 1 and are arranged on both sides of the bottom plate pressing assembly 4. The side plate pressing assemblies 3 are driven to reciprocate horizontally on the workbench 1 by a translation mechanism.

[0039] As Figure 8 shown, an inner guide rail perpendicular to the top cross beam 22 is fixedly installed on the workbench 1, and the two side plate pressing assemblies 3 are slidably installed on the inner guide rail. The translation mechanism includes a pressing cylinder 30 fixedly installed on the bottom surface of the workbench 1, and the piston rod of the pressing cylinder is fixedly connected to the side plate pressing assembly 3. During operation, the two side plate pressing assemblies 3 are driven to translate independently by two translation cylinders.

[0040] The side plate pressing assembly 3 and the bottom plate pressing assembly 4 include a heat-conducting silica gel, a heating plate, an electric heating sheet, a heat-insulating plate and a bracket fixedly connected in sequence starting from the position where the heating station is located. The bracket in the bottom plate pressing assembly 4 is fixedly connected to the workbench, and the bracket in the side plate pressing assembly 3 is installed on the inner guide rail and fixedly connected to the piston rod of the translation cylinder.

[0041] As Figure 9 shown, during use, after the two side plate pressing assemblies 3 are brought closer, they clamp and heat the double-row module in the heating station together with the bottom plate pressing assembly 4. And during the heating process, a plurality of groups of downward pressing pole blocks 23 press on the pole columns of each battery cell after descending, thus effectively avoiding the problem of battery cell offset during the heating process. Moreover, the application of the variable pitch mechanism also enables this case to be applicable to heating double-row modules of two different specifications, namely long and short.

[0042] There are many specific implementation ways of the present utility model. The above description is only the preferred implementation manner of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements can still be made, and these improvements should also be regarded as the protection scope of the present utility model.
