The bayonet 11 is used for accommodating the packing belt 2, so that the packing belt 2 passes through the bayonet 11, and the packing belt 2 can be contacted with the edge part of the photovoltaic module 4, so that the photovoltaic module 4 can be packed more firmly.
It can be understood that, in order to make the packing belt 2 pass through each bayonet 11 and be in full contact with the edge portion of the stacked photovoltaic module 4 after being tensioned, the depth of the bayonet 11 needs to be greater than or equal to the distance from the edge portion of the photovoltaic module 4 corresponding to the bayonet 11 to the corresponding side of the tray 1, so that after the photovoltaic module 4 is stacked on the tray 1, the edge portion of the photovoltaic module 4 extends out of the bottom of the bayonet 11, which can ensure that the packing belt 2 can be in full contact with the edge portion of each layer of photovoltaic module 4 after passing through the bayonet 11 and being tensioned, so that the stacked photovoltaic module 4 is completely fixed through the packing belt 2, and the photovoltaic module 4 is prevented from moving back and forth in the transportation process and being damaged by the photovoltaic module 4.
It should be noted that the bayonets 11 may be disposed on two opposite sides of the tray 1 along the length direction, or may be disposed on two opposite sides of the tray 1 along the width direction, and of course, the bayonets 11 may be disposed on two opposite sides of the tray 1 along the length direction and two opposite sides of the tray 1 along the width direction, so as to fix the peripheral edge portions of the photovoltaic modules 4, respectively, so that the photovoltaic modules 4 are more firmly fixed.
When the bayonets 11 are arranged on two opposite side edges of the tray 1 in the length direction, the bayonets 11 on the two opposite side edges in the length direction are symmetrically arranged about the central line of the tray 1 in the length direction; when the bayonets 11 are provided on the two sides of the tray 1 opposite in the width direction, the bayonets 11 on the two sides opposite in the width direction are provided symmetrically with respect to the center line of the tray 1 in the width direction.
In view of the convenience of packaging, and in order to make the photovoltaic module 4 packaged more firmly, it is preferable that the number of the packaging tapes 2 is the same as the number of pairs of the bayonets 11 on the two opposite sides of the tray 1, and each pair of the bayonets 11 is symmetrical with respect to the center line of the tray 1, that is, one packaging tape 2 passes through two opposite bayonets 11, thereby clamping and fixing the two opposite sides of the tray 1. When tray 1 all was equipped with bayonet 11 along two opposite sides on length direction and two opposite sides on the width direction, packing area 2 is the # -shaped packing mode to fix photovoltaic module 4's the edge portion all around.
From this, can see, the utility model provides a packing plant is used in transportation of photovoltaic module short distance improves the customization wooden case that is used for short distance transportation photovoltaic module 4 among the prior art for tray 1, and set up bayonet socket 11 about 1 central line symmetry of tray through relative both sides on tray 1, utilize packing area 2 to pass from bayonet socket 11, make packing area 2 take up the back and laminate the contact completely with the edge part of range upon range of photovoltaic module 4, thereby fix the photovoltaic module 4 of range upon range of stack completely, avoid photovoltaic module 4 round trip movement in the transportation, cause photovoltaic module 4's damage.
That is to say, the utility model realizes simple packaging of short-distance transportation of the photovoltaic module 4 by matching the tray 1 provided with the bayonet 11 and the packing belt 2, and has simple structure, convenient operation, safety, reliability and low cost; in addition, because the manufacturing of the tray 1 is very simple, the packing belt 2 is also a common material and has wide sources, when the tray 1 is customized by a manufacturer, the delivery cycle is short; and when urgent appearance demand that send, tray 1 can also be directly formed by current conventional tray 1 transformation, consequently, can guarantee the ageing of pay-off progress.
In order to further make the photovoltaic module 4 packed more firmly, on the basis of the above embodiment, the bayonet 11 has a preset depth, so that the edge portion of the photovoltaic module 4 protrudes beyond the groove bottom of the bayonet 11 by a distance of 1mm or more.
