[0073] It is easy to understand that, by setting the slide rail 280, this embodiment also enables the stacking fixture to move smoothly and stably, reducing up-and-down shaking and flow noise, while not affecting the fixation of the sheet material.

[0074] In some specific embodiments of this utility model, the slide rail 280 at the bottom of the substrate 300 can be a rail groove, and the battery cell production equipment is provided with a guide rail that matches the rail groove. Therefore, the physical entity forming the rail groove can be reduced, so that the total volume and weight of the guide rail and the physical entity forming the rail groove are smaller. Moreover, it helps to reduce the space occupied and facilitates the arrangement.

[0075] Specifically, the guide rail on the battery cell production equipment is long, if the battery cell production equipment is provided with a rail groove for circulation, the entity forming the rail groove is long, which causes the volume of the sliding rail 280 to increase, the occupied space to increase, and the weight to increase, and meanwhile, the rail groove needs to be arranged open upward, which is easy to accumulate foreign matters and increase wear, and the bottom of the base plate 300 is provided with the rail groove, which can avoid the above problems.

[0076] In some specific embodiments of the utility model, the bottom of the base plate 300 is provided with parts forming the rail groove, so as to reduce the manufacturing cost, facilitate maintenance through replacement, and reduce the use cost.

[0077] In some specific embodiments of the utility model, the base plate 300 is provided with a positioning taper block 290 or a V-shaped positioning groove, and the lamination jig is positioned through the positioning taper block 290 and the V-shaped positioning groove at each station of the battery cell production equipment.

[0079] In some specific embodiments of the utility model, the front side of the base plate 300 is provided with a hooking part, and the lamination jig is also driven to move through the hook pulling mode.

[0081] Specifically, for the supporting module, the supporting module includes a supporting seat 100 and a detachable pad plate arranged at the top of the supporting seat 100, the pad plate is used for placing the sheet materials, and the inside of the supporting seat 100 is through from top to bottom, so that the bottom of the pad plate is suspended.

[0082] For the pressing module, the pressing module includes at least one pair of pressing knives, and the pair of pressing knives is used for pressing two opposite sides of the sheet materials to fix the stacked sheet materials on the pad plate.

[0083] It is easy to understand that, in the embodiments, the detachable pad plate is arranged, so that the pad plate can be replaced according to the production needs to meet the needs of different products.

[0084] Specifically, when it is required to produce flat plate battery, the utility model can adopt higher strength backing plate to resist the pressing force of hot-pressing die, so as to meet the requirement of producing flat plate battery.

[0085] When it is required to produce arc-shaped battery, the utility model sets the support base 100, so that the inside of the support base 100 is through from top to bottom, and the bottom of the backing plate is suspended, and then the deformable backing plate is replaced, so that the hot-pressing die can extrude the backing plate and the sheet material from the top and bottom direction of the backing plate, so that the sheet material and the backing plate can be deformed at the same time to produce arc-shaped battery.

[0086] Compared with the prior art, the lamination jig of the utility model can meet the production requirements of flat plate battery and arc-shaped battery at the same time, and the sheet material does not need to be pre-bent, so that the production process is simplified and the lamination difficulty is not increased.

[0087] Meanwhile, the lamination jig is applied, so that the utility model has the dual capability of producing flat plate battery and arc-shaped battery, the capability of the equipment is expanded, the equipment is easy to be universal, and the equipment cost of producing battery is reduced.

[0094] In some specific embodiments of the utility model, the support base 100 can be provided with two through cavities which are through from top to bottom, and two backing plates are installed correspondingly to meet the requirements of stacking and fixing two stacks of sheet materials.

[0095] In some specific embodiments of the utility model, the battery production equipment can include an upper top piece, and when the lamination is carried out, the upper top piece can support the backing plate to avoid that the stacked sheet material is skewed due to the deformation of the backing plate.

[0096] In some specific embodiments of the utility model, the support base 100 can be adjusted in lifting.

[0097] It is easy to understand that the support base 100 can be adjusted in lifting, so that the sheet material at the highest position is at the same height, and the mechanical hand for taking and placing the sheet material during lamination is not needed to be adjusted, and the repeated adjustment of the battery cell production equipment is reduced.

[0098] In some specific embodiments of the utility model, the base plate 300 can be provided with a pair of screw rod structures driven by a motor, the motor is rotated to drive the screw rod to rotate, and then the screw sleeve on the screw rod is lifted, and the screw sleeve is installed on the support base 100, so that the lifting adjustment of the support base 100 can be realized.

[0099] The embodiment can also be adjusted in other ways, such as gear and rack transmission, cam or eccentric wheel transmission, etc.

[0100] At the same time, the support base 100 can be adjusted in lifting, which can also provide another lamination mode, for example, during lamination, the pressing knife only has the ability of translation, and the lifting function is performed by the support base 100. In order not to affect lamination, the pressing module comprises a lifting assembly and a translation assembly, the lifting assembly is used to drive the pressing knife to lift, and the translation assembly is used to drive the pressing knife to translate, the lifting assembly comprises a side moving piece 320, and the power outside the lamination jig drives the side moving piece 320 to move, so that the pressing knife corresponds to lifting.

[0101] It is easy to understand that the side moving piece 320 is arranged, so that when the lamination jig flows through each process, the external power drives the side moving piece 320 to move, so that the lifting assembly can play a role, the need of driving the pressing knife to lift is met, at the same time, the power does not need to be arranged on the lamination jig, the structure of the lamination jig is simplified, the weight and manufacturing cost of the lamination jig are reduced, and the flow is facilitated.

[0102] In some specific embodiments of the utility model, the side moving piece 320 can be provided with a rolling bearing, so that the battery cell production equipment can abut against the rolling bearing through a cam, and the effect of driving the side moving piece 320 to move is achieved.

[0103] In some specific embodiments of the utility model, the battery cell production equipment can directly push or pull the side moving piece 320 through a pneumatic cylinder, a hydraulic cylinder or the like. In the embodiment, the pneumatic cylinder is used to directly push the side moving piece 320 to move, which is convenient and fast, and the initial state of the pneumatic cylinder does not affect the flow of the lamination jig.

[0104] In some specific embodiments of the utility model, the translation assembly can comprise a side moving piece 320, and the power outside the lamination jig drives the side moving piece 320 to move, so that the pressing knife corresponds to translation.

[0105] It is easy to understand that, by setting the side moving piece 320, when the lamination fixture is circulated in each process, the external power drives the side moving piece 320 to move, so that the translation assembly can be used to meet the need of driving the pressing knife to translate, and the power does not need to be arranged on the lamination fixture, so that the structure of the lamination fixture is simplified, the weight and manufacturing cost of the lamination fixture are reduced, and circulation is facilitated.

[0106] In the structure, the side moving piece 320 of the translation assembly can also be provided with a rolling bearing and driven by similar power, so that the specifications of parts are reduced and the manufacturing cost is reduced.

[0110] It is easy to understand that, by making the lifting assembly comprise the first roller 250 and the first inclined block 240, when the first roller 250 rolls along the first inclined block 240, the first roller 250 or the first inclined block 240 can generate displacement in the up-down direction, so that the translation movement can be converted into lifting movement, which meets the need of lifting the pressing knife, reduces the occupied space in the up-down direction, makes the lamination fixture relatively flat, and facilitates transfer and circulation, such as lifting the lamination fixture to return the lamination fixture.
