Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic equipment manufacturing, in particular to a battery string soldering and mesh pressing tooling. Background Art
[0002] The welding of the battery string of the photovoltaic module is one of the most important production processes in the whole photovoltaic module welding process. In the production process of the battery module, there is a process of stacking and welding the battery chips and the welding tapes to form a battery string. Among them, when stacking the battery chips and the welding tapes, a pressing tooling is required to press and position the welding tapes. At present, multiple sets of toolings are required when the battery chip screen and the rectangular battery change, resulting in an increase in the cost of the mesh pressing tooling.

[0005] The mesh pressing main body includes a first cross bar connected to two end covers, and a notch is opened on the outer first cross bar;
[0006] The adjusting part includes a second cross bar, both ends of the second cross bar are connected to connecting blocks, the second cross bar is connected to a clamping block through a connecting rod, and the clamping block is connected to the first cross bar through the notch.
[0007] As a preferred technical solution of the utility model, the length of the first cross bar is equal to the length of the second cross bar.
[0008] As a preferred technical solution of the utility model, adjacent first cross bars are connected by reinforcing ribs.
[0009] As a preferred technical solution of the utility model, the notch is connected to the clamping block by screws.
[0010] As a preferred technical solution of the utility model, the length of the connecting rod is 15 - 20 mm.
[0011] As a preferred technical solution of the utility model, the shape of the notch is "U" shaped.
[0012] As a preferred technical solution of the utility model, through holes are opened on both the first cross bar and the second cross bar, and pressing needles are installed in the through holes.
[0013] Since the utility model adopts such a structure, the length of the connecting rod of the second cross bar can be adjusted according to production needs, and it can be applicable to various grid line spacings. Normal production can be achieved regardless of the change in the size of the battery cell. Description of the Drawings
[0014] Figure 1 It is a schematic structural diagram of a battery cell series welding and mesh pressing tooling of the utility model.
[0015] In the figure: 1 is the first cross bar, 2 is the end cover, 3 is the reinforcing rib, 4 is the second cross bar, 5 is the connecting rod, 6 is the notch, 7 is the connecting block, 8 is the clamping block, and 9 is the through hole. Detailed Implementation Modes
[0016] The following further elaborates on the utility model in detail in conjunction with the drawings and specific embodiments.
[0017] As Figure 1 shown, a battery cell series welding and mesh pressing tooling of the utility model includes an adjusting part that cooperates with the mesh pressing main body;
[0018] The mesh pressing main body includes a first cross bar 1 connected to two end covers 2, and a notch 6 is formed on the outer first cross bar 1;
[0019] The adjusting part includes a second cross bar 4. Both ends of the second cross bar 4 are connected to a connecting block 7. The second cross bar 4 is connected to a clamping block 8 through a connecting rod 5, and the clamping block 8 is connected to the first cross bar 1 through the notch 6. The mesh pressing main body and the adjusting part can be adjusted according to production needs. That is, a large-size battery cell mesh plate and a rectangular battery cell can be connected through the clamping block 8 and the notch 6, so that the adjusting part is connected to the mesh pressing main body. The utility model can be applicable to various grid line spacings, is convenient and efficient to use, and has good practicability.
[0020] Further, the length of the first cross bar 1 is equal to the length of the second cross bar 4. The first cross bar 1 and the second cross bar 4 with equal lengths can achieve efficient production.
[0021] Further, adjacent first cross bars 1 are connected by a reinforcing rib 3. The reinforcing rib 3 can enhance the stability of the mesh pressing main body.
[0022] Further, the notch 6 is connected to the clamping block 8 by screws. The screws can make the connection between the notch 6 and the clamping block 8 more firm, that is, the first cross bar 1 and the second cross bar 4 can be kept stable.
[0023] Further, the length of the connecting rod 5 is 15 - 20 mm, and preferably the length of the connecting rod 5 is 17 mm. The connecting rod 5 with an appropriate length can be selected according to production needs, that is, the second cross bar 4 with a matching length can be selected.
[0024] Furthermore, in the present utility model, the shape of the notch 6 is "U"-shaped. The "U"-shaped notch 6 has better stability, thereby avoiding deviation when the second crossbar 4 and the first crossbar 1 are combined.
[0025] Furthermore, in the present utility model, through holes 9 are provided on both the first crossbar 1 and the second crossbar 4, and press pins are installed in the through holes 9. By fixing the welding tape with the press pins, the deviation of the welding tape can be avoided.
