[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] like Figures 1-4 The tooling shown includes a base 1 and several counterweights 2, which can be stacked on the base 1.

[0024] The base 1 is vertically provided with several limiting rods 103 at its top, and several limiting holes 201 are provided on the counterweight plate 2. Each set of limiting holes 201 corresponds one-to-one with each set of limiting rods 103. Each set of limiting rods 103 can pass through the limiting holes 201 to position multiple sets of counterweight plates 2.

[0025] During the process of applying adhesive to the surface of the battery cell and pressing it into a plate, it is necessary to ensure the uniformity of the adhesive application and the bonding effect of the plate. It is necessary to add weight to the plate to ensure the pressing effect. In this application, the substrate is placed on the upper side of the steel plate after the adhesive has been applied, and the weight is added one by one by the counterweight 2 to ensure the pressing effect.

[0026] The counterweights 2 are stacked upwards in sequence under the action of the limiting rod 103, and the limiting rod 103 can limit the counterweights 2 and prevent them from shifting and collapsing, thereby damaging the battery cell.

[0027] Preferably, a plurality of sleepers 101 are installed at the bottom of the base 1. The sleepers 101 can apply downward pressure to the upper part of the battery cell while also providing protection, preventing the base 1 from directly colliding with the battery cell and thus damaging it.

[0028] Preferably, each set of sleepers 101 is provided with a rubber pad 102 at its bottom. The rubber pad 102 can further provide protection.

[0029] Preferably, the outer side wall of each set of limiting rods 103 is provided with threads. After positioning the stacked counterweights 2, they are screwed to the limiting rods 103 by nuts 104, which are located above the topmost counterweight 2.

[0030] After the required counterweights 2 are stacked, use nut 104 to tighten the top of the uppermost counterweight 2 for positioning, which serves to secure the counterweights 2 after stacking, integrate the stacked counterweights 2 into one unit, and facilitate subsequent transportation after the pressure plate process is completed.

[0031] Preferably, each set of counterweight plates 2 has two rows of parallel mounting holes 202 at its top, with two sets in each row. Each set of mounting holes 202 can be detachably fitted with a positioning ring 203. Each mounting hole 202 of the topmost counterweight plate 2 is fitted with a positioning ring 203. The inner rings of the two positioning rings 203 on each row of mounting holes 202 can be connected to a lifting rod 3.

[0032] The topmost counterweight 2 is equipped with a positioning ring 203. The lifting rod 3 can pass through the inner hole of each row of positioning rings 203, and the worker can use the lifting rod 3 to move the counterweight 2.

[0033] Preferably, the base of the positioning ring 203 can be threaded to the inner wall of the mounting hole 202. The positioning ring 203 does not need to be installed between adjacent counterweights 2, otherwise it will affect the stacking. The top of the topmost counterweight 2 needs to be equipped with a positioning ring 203 to lift all the counterweights 2 for transfer.

[0034] Preferably, each set of the lifting rod 3 can be detachably installed with two sets of positioning bolts 301, and the two sets of positioning rings 203 that are sleeved with the lifting rod 3 are located between the two sets of positioning bolts 301, which can play a limiting role and ensure that the counterweight plate 2 is located in the middle of the lifting rod 3, which facilitates subsequent transportation.

[0035] In the process of applying glue to the pressing plate, weights can be freely added to the upper part of the pressing plate to reduce the pressing time. This tooling can be operated by 2 people, compared with the old tooling which required 4 people, reducing manpower and saving time and effort.

[0036] Each tooling can bear weight independently and can independently press a single module plate. The plate will not shift due to tooling offset. The positioning tooling can be installed in advance before installing the plate to ensure the straightness and portability of the plate. Then, according to the actual needs, the counterweights 2 are stacked on top of each other. Under the action of the limit rod 103, the stacked counterweights 2 will not shift.
