The embodiment provides a polar plate 60 clamp which can reduce the probability of bending deformation of the polar plate 60 when the polar plate 60 enters a high-temperature environment.

As shown in fig. 1 to 7, the plate 60 jig includes a base plate 10. The middle part of one side surface of the bottom plate 10 is provided with a hollow first saddle structure 20, the surface of the first saddle structure 20 is provided with a plurality of adsorption holes 21, and the plurality of adsorption holes 21 are used for adsorbing the polar plate 60 positioned on one side surface of the bottom plate 10, so that the polar plate 60 can be attached to the first saddle structure 20. And, the one side surface of the base plate 10 is further provided with an annular pallet structure 30 surrounding the first pallet structure 20, the annular pallet structure 30 being for supporting an edge portion of the plate 60.

In the polar plate 60 anchor clamps that this embodiment provided, the surface of first saddle structure 20 has the adsorption hole 21 that is used for adsorbing polar plate 60, make can inhale tightly and fixed to the central zone of polar plate 60 through this adsorption hole 21, the bending resistance of polar plate 60 has been improved, the condition of polar plate 60 bending deformation that has prevented to lead to because polar plate 60 is too thin and is located the solid environment of high temperature for a long time, can guarantee when the operation of point gum, the planarization on polar plate 60's surface, simultaneously reduced the point gum and done all the back, when sealed glue high temperature curing, the probability that bending deformation takes place for polar plate 60, promote the off-the-shelf quality and the quality of polar plate 60, the defective rate of polar plate 60 has been reduced.

Alternatively, as shown in fig. 3, the suction holes 21 of the first pallet structure 20 may extend to the other side of the base plate 10 (i.e., the bottom surface of the base plate 10), and the plurality of suction holes 21 may be connected to a suction device, so that the suction device can suck air in the suction holes 21 to reduce the air pressure in the suction holes 21, thereby achieving the purpose of sucking the plate 60 on the surface of the first pallet structure 20.

In this embodiment, as shown in fig. 2, a gap exists between the first pallet structure 20 and the ring-shaped pallet structure 30, and when the plate 60 is located on one side surface of the base plate 10, the seal bead of the plate 60 is located in the gap. That is, a first distance exists between the first pallet structure 20 and the annular pallet structure 30, and when the pole plate 60 is located on the surface of one side of the base plate 10, the sum of a second distance between the sealing rubber channel of the pole plate 60 and the first pallet structure 20 and a third distance between the sealing rubber channel and the annular pallet 30 is smaller than the first distance, so that the first pallet structure 20 and the annular pallet structure 30 do not contact the sealant in the sealing rubber channel of the pole plate 60, and the sealant in the sealing rubber channel has better sealing performance.

Alternatively, the length of the first pallet structure 20 in the first direction is equal to the length of the ring-shaped pallet structure 30 in the first direction, which is parallel to the thickness direction of the base plate 10. That is, the height of the first pallet structure 20 with respect to the base plate 10 is the same as the height of the ring-shaped pallet structure 30 with respect to the base plate 10, so that when the pole plate 60 is located on the surface of one side of the base plate 10, the surface of the pole plate 60 close to the base plate 10 can be simultaneously in contact with the first pallet structure 20 and the ring-shaped pallet structure 30, so as to improve the supporting effect of the first pallet structure 20 and the ring-shaped pallet structure 30 on the pole plate 60.

The length of the positioning fence 40 in the first direction is greater than the length of the ring-shaped pallet structure 30 in the first direction, that is, the height of the positioning fence 40 with respect to the base plate 10 is higher than the height of the ring-shaped pallet 30 with respect to the base plate 10. The positioning baffle 40 is used for positioning and shielding the polarity of the polar plate 60 on the surface of one side of the bottom plate 40, so as to ensure that the adsorption hole 21 in the first saddle structure 20 can effectively adsorb the middle area of the polar plate 60. Moreover, the arrangement of the positioning baffle 40 can quickly position and prevent the pole plate 60, thereby improving the speed and efficiency of preventing the pole plate 60.

Optionally, as shown in fig. 4 to 7, the plate 60 jig further includes a plurality of pressers 50. The plurality of pressing pieces 50 are used for pressing the edge portion of the pole plate 60 on one side surface of the base plate 10, so that the edge portion of the pole plate 60 is fixedly supported by the annular saddle structure 30 and the pressing pieces 50, and the probability of bending deformation of the edge portion of the pole plate 60 under a high-temperature environment is further reduced.

Further, the material of the base plate 10 and the annular pallet structure 30 is a metal material, the material of the pressing member 50 is a magnet, at this time, one end of the pressing member 50 is magnetically connected with the base plate 10, and the other end of the pressing member 50 is used for pressing the edge portion of the pole plate 60, so that the edge of the pole plate 60 is fixed between the pressing member 50 and the base plate 10 (or the annular pallet structure 30) through the magnetic force between the pressing member 50 and the base plate 10 (or the annular pallet structure 30). The pressing member 50 is connected with the base plate 10 by means of magnetic attraction, so that the pressing member 50 can be conveniently installed on the base plate 10 or removed from the base plate 10.

As shown in fig. 4 and 5, the edge of the base plate 10 may have a protrusion structure, which defines a groove on the base plate 10, and the first pallet structure 20 and the ring-shaped pallet structure 30 are located in the groove. At this time, one end of the pressing piece 50 abuts against the inner side of the convex structure, so that the pressing piece 50 can slide in the groove formed by the convex structure and the annular saddle structure 30, so as to adjust the position of the pressing piece 50. Alternatively, the pressing member 50 may be a pressing piece.

Alternatively, one end of the pressing member 50 in this embodiment is rotatably connected to the base plate 10, and the other end of the pressing member 50 is used to press the edge portion of the electrode plate 60. When it is required to place the plate 60 on the surface of one side of the base plate 10, the pressing piece 50 may be rotated to the outside of the base plate 10 to avoid interference with the placement of the plate 60. When it is necessary to fix the electrode plate 60, the pressing member 50 may be rotated to the inner side of the base plate 10 and the other end of the pressing member 50 may be pressed against the edge portion of the electrode plate 60.
