"upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships are changed accordingly.

First, a punching apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 to 3, a punching apparatus according to an embodiment of the present invention includes a connecting portion 1, a cutter 2, and a marking portion 3. The connecting part 1 is used for being fixed at the lower end of the cylinder; the upper end of the cutter 2 is fixed on the connecting part 1, and the blade part at the lower end of the cutter 2 protrudes from the lower surface of the connecting part 1; the seal of a government organization in old china portion 3 is connected at the lower surface of connecting portion 1 for seal the seal of distinguishing positive negative pole on the backplate.

That is to say, be connected with the cylinder through connecting portion 1, the bottom is installed the cutter 2 that can punch a hole, and cutter 2 carries out up-and-down motion in order to punch a hole to the solar energy backplate under the drive of cylinder. The seal mark part 3 capable of obviously distinguishing the positive electrode and the negative electrode is further arranged on the lower surface of the connecting part 1, and the seal mark part 3 can impact the surface of the solar backboard when the cutter 2 falls down, so that the seal mark is printed on the backboard, and a worker can distinguish the positive electrode and the negative electrode according to the seal mark. The punching device avoids the step of manually pasting the bar codes, and marks are easy to distinguish, so that the labor cost is saved, the automation degree is improved, and the product error rate is reduced.

Further, as shown in fig. 3, the print portion 3 includes at least one of the positive print portion 4 and the negative print portion 5, the positive print portion 4 includes a cross-shaped print, and the negative print portion 5 includes a line-shaped print.

The mark part 3 respectively adopts a cross-shaped mark and a straight-shaped mark to represent the anode and the cathode, and the workers can easily recognize the marks. It should be noted that only one positive electrode marking portion 4 may be provided, or only one negative electrode marking portion 5 may be provided, and the marking-bearing identification may be performed, and the other electrode, which is not marked and is known as the default by the operator, may be also easily operated. Of course, the positive electrode stamp portion 4 and the negative electrode stamp portion 5 are provided at the same time, so that they can be recognized more directly and clearly, and the error rate can be further reduced.

Further, as shown in fig. 1 to 3, since the solar cell module generally includes two bus bar lead-out wires, two holes are required to be opened on the back plate to lead out the two bus bar lead-out wires, respectively, and therefore, the cutter 2 includes a first cutter 6 and a second cutter 7, the first cutter 6 is arranged in parallel with the second cutter 7, and accordingly, the print portion 3 includes a positive print portion 4 and a negative print portion 5, and the positive print portion 4 and the negative print portion 5 are arranged outside the first cutter 6 and the second cutter 7, respectively.

If only one cutter 2 is provided, the punching needs to be performed twice, and the amplitude of one punching is smaller than that of the other punching to prevent two identical marks from being printed. In order to reduce the number of times of punching a hole and avoid the misprint condition to appear, this scheme sets up two cutters 2 to set up anodal seal of a government organization in old china and a government organization in old china in two cutters 2 outsides respectively, can save time and can reduce the error rate again.

Further, as shown in fig. 3, the positive electrode print portion 4 further includes a U-shaped frame 8 surrounding the cross-shaped print, and the negative electrode print portion 5 further includes a U-shaped frame 8 surrounding the in-line print.

Cross seal of a government organization in a government is small in a government organization in a government and the public.

Further, as shown in fig. 1 to 3, the connecting portion 1 includes a cylinder connecting shaft 9, a connecting plate 10, and a mounting portion 11. The cylinder connecting shaft 9 comprises a first connecting block at the upper end, a second connecting block at the lower end and a connecting column connected between the first connecting block and the second connecting block, wherein the first connecting block is detachably fixed at the lower end of the cylinder; the connecting plate 10 is detachably fixed on the lower surface of the second connecting block; the mounting portion 11 is detachably fixed to the lower surface of the connecting plate 10, wherein the cutter 2 and the marking portion 3 are respectively provided to the mounting portion 11.

Connecting portion 1 comprises cylinder connecting axle 9, connecting plate 10, installation department 11 triplex, and these triplexes all are detachably connected together, if connecting portion 1 adopts overall structure, appear damaging in the use, need be with the whole replacement of connecting portion 1, cost of maintenance is great. And adopt connecting portion 1 that the triplex is constituteed, because the position that connecting portion 1 damaged mainly takes place in installation department 11, consequently only need change installation department 11 can, practiced thrift cost of maintenance effectively.

Further, as shown in fig. 1 to 3, the mounting portion 11 is formed in a plate shape, the mounting portion 11 is formed with a first mounting hole 12 penetrating the mounting portion 11 in the up-down direction, the mounting portion 11 is mounted on the lower surface of the connecting plate 10 by passing a bolt 13 through the first mounting hole 12, a second mounting hole 14 is provided in the lateral direction of the mounting portion 11, a mounting groove 15 is provided on the lower surface of the mounting portion 11, the upper end of the tool 2 is positioned in the mounting groove 15 and the tool 2 is fixed in the mounting groove 15 by passing the bolt 13 through the second mounting hole 14.

That is to say, cutter 2 installs at installation department 11 lower surface through detachable mode, because cutter 2 damages the probability great, needs to restore or the number of times of changing more, therefore detachable connected mode is favorable to the maintenance.

Further, as shown in fig. 3, the first mounting hole 12 is formed as a counter-sunk hole.

The first mounting hole 12 adopts a counter bore to wrap the bolt 13 in the mounting hole, so that the appearance is smooth and attractive, and the hidden trouble caused by the protrusion of the bolt 13 can be avoided.
