when the photovoltaic module 20 is installed in the loading space, the press-connection assembly 11 drives the electric injection assembly 12 to press against the photovoltaic module 20 for electric injection.

Specifically, as illustrated in fig. 1 and 2, in one embodiment, the photovoltaic module electrical injection carrier of the embodiment of the present utility model includes a carrier body 10, a crimping assembly 11, and an electrical injection assembly 12. The carrying body 10 is a main body part of the electric injection carrier, and may be a frame structure or a flat plate member with a hollowed-out area. The bearing body 10 is provided with a bearing space for loading the photovoltaic module 20, and the crimping module 11 can move relative to the bearing body 10 after being connected with the bearing body 10. After the photovoltaic module 20 is loaded into the bearing space on the bearing body 10 by the material transfer module 30, the press-connection module 11 can stably press-connect and fix the photovoltaic module 20 in the bearing space, so that shaking of the photovoltaic module 20 is prevented when the electric injection carrier moves up and down. The press-connection assembly 11 can drive the electric injection assembly 12 connected with the press-connection assembly to stably press on the electric contact on the surface of the photovoltaic assembly 20, and continuously and stably supply power to the photovoltaic assembly 20 through the electric injection assembly 12.

The pressing assembly 11 may be a manually operated assembly or an assembly that applies pressure to the photovoltaic assembly 20 under the triggering of the material transfer assembly 30, and the specific structural form of the pressing assembly is not limited to an assembly that uses a driving device such as a motor or a cylinder as a power source to drive a pressing block or a pressing rod to apply force.

According to the photovoltaic module electric injection carrier, the compression joint assembly connected with the bearing body is utilized, so that the photovoltaic module can be driven to be fixedly held in the bearing space in a compression joint mode, the phenomenon of poor contact between the electric injection assembly and the contact of the photovoltaic module can be reduced, reliability in electric injection can be improved, and normal electric injection is ensured.

Specifically, as shown in fig. 1 and fig. 2, in one embodiment, the carrying body 10 includes a carrying frame 101 and a supporting frame 102, where the carrying frame 101 is a frame structure with a bearing function made by connecting metal profiles, the supporting frame 102 may also be a frame structure made by connecting metal profiles, the supporting frame 102 and the carrying frame 101 are arranged vertically opposite to each other, the supporting frame 102 is located above the carrying frame 101, a space between the two is larger than the thickness of the photovoltaic module 20, that is, a carrying space, and when the photovoltaic module 20 is located in the carrying space, the bottom of the photovoltaic module 20 is supported by the carrying frame 101, and the top of the photovoltaic module 20 is the supporting frame 102.

It is easy to understand that the external transmission device can make the photovoltaic module 20 move along the horizontal direction in the horizontal posture, insert into the bearing space from the side surface of the bearing body 10, and meanwhile, the material transfer module 30 below the electric injection carrier is in a lifting state by penetrating through the hollow channel, and the photovoltaic module 20 can be conveyed onto the material transfer module 30. Then, as shown in fig. 4, when the material transfer module 30 falls down, the material transfer module 30 is separated from the photovoltaic module 20, the photovoltaic module 20 falls on the carrier 101 to be supported by the carrier 101, and the press-connection module 11 connected to the support frame 102 applies pressure to the photovoltaic module 20 from the top of the photovoltaic module 20 to press and fix the photovoltaic module 20.

When the material transfer assembly 30 passes through the hollowed-out channel to lift the photovoltaic assembly 20, the bearing effect of the bearing frame 101 on the photovoltaic assembly 20 fails, at this time, the material transfer assembly 30 can drive the photovoltaic assembly 20 to move along the horizontal direction, the photovoltaic assembly 20 is output from the bearing space, and the discharging of the photovoltaic assembly 20 is completed.

When the electric injection assembly 12 moves downwards under the driving of the compression assembly 11, the compression fixing function can be achieved on the photovoltaic assembly 20 located below the support frame 102. Conversely, when the electric injection assembly 12 moves upwards under the driving of the compression assembly 11, the photovoltaic assembly 20 located below the supporting frame 102 can be released.

At this time, once the photovoltaic module 20 is loaded in the bearing space, the press-connection assembly 11 stably and reliably presses the photovoltaic module 20 in the bearing space under the elastic force of the elastic member 115, so as to realize the self-locking and retaining function of the photovoltaic module 20, and prevent the loosening of the photovoltaic module 20 caused by unexpected reverse rotation of the rotating shaft 113.

Elastic pieces such as springs or rubber can be further added between the wheel axle connecting plate 132 and the conductive wheel bracket 131, and the conductive wheel 133 is forced to be pressed on the surface of the electric rail through the elastic force of the elastic pieces, so that the conductive wheel 133 and the electric rail are in close contact, poor contact can be avoided, meanwhile, discharge arcing phenomenon between the conductive wheel 133 and the electric rail can be avoided, and the photovoltaic module 20 is prevented from being damaged by electric arcs.

Optionally, referring to fig. 11, the electrical injection assembly 12 includes a conductive ram 121, a guide sleeve 122, a guide rod 123, and a buffer mechanism 124;

the conductive pressure head 121 is fixed at the end of the guide rod 123, and the conductive pressure head 121 is electrically connected with the power supply assembly 13;

the guide rod 123 is inserted into the guide sleeve 122, and the buffer mechanism 124 is disposed between the guide sleeve 122 and the guide rod 123.

Specifically, the embodiment of the present utility model also provides a structure of the electric injection assembly 12, as schematically shown in fig. 11, where the electric injection assembly 12 includes a conductive ram 121, a guide sleeve 122, a guide rod 123, and a buffer mechanism 124. The conductive pressure head 121 has a columnar connection portion and a contact portion located at an end of the columnar connection portion, the contact portion being made of a conductive material. The guide rod 123 is a straight rod-shaped part, and a blind hole is formed in the end of the guide rod 123 and can be used for installing and fixing the conductive pressure head 121. For example, the conductive ram 121 may be threaded into the blind bore to connect with the guide rod 123. The contact portion of the conductive ram 121 may be electrically connected to the power supply assembly 13 by wires so that current may be transferred to the contact portion of the conductive ram 121. The guide sleeve 122 may be a sleeve-shaped part having a hollow channel, the guide rod 123 is disposed through the guide sleeve 122, the conductive ram 121 is exposed from one end of the guide sleeve 122, the guide rod 123 may slide in the guide sleeve 122 along an axial direction of the guide sleeve 122, and the buffer mechanism 124 is disposed between the guide sleeve 122 and the guide rod 123.

Fig. 12 also shows a structure of a buffering mechanism 124, where the buffering mechanism 124 may include a transition guide rod 1241 and two springs with different sizes, the transition guide rod 1241 is penetrated in the guide sleeve 122, the guide rod 123 is penetrated in the transition guide rod 1241, the large spring 1242 is sleeved between the transition guide rod 1241 and the guide sleeve 122, and the small spring 1243 is sleeved between the guide rod 123 and the transition guide rod 1241. Two springs form a two-stage buffer mechanism, so that the buffer performance is more excellent. It will be readily appreciated that in some embodiments, the damping mechanism 124 may also include a spring or rubber cushion or the like disposed between the guide sleeve 122 and the guide rod 123.

Referring to fig. 11, when the guide sleeve 122 of the electric injection assembly 12 is fixed on the fixing base 111 and the guide rod 123 is fixed with the connecting pressing plate 118, the conductive pressing head 121 can be gradually close to the photovoltaic assembly 20 below until contacting with the photovoltaic assembly 20 as the connecting pressing plate 118 drives the guide rod 123 to move downwards. After contact, since the buffer mechanism 124 also has buffer space, the conductive ram 121 may continue to press down until the buffer space of the buffer mechanism 124 is consumed. By arranging the buffer mechanism between the guide sleeve 122 and the guide rod 123, the contact and press connection process of the conductive pressure head 121 and the photovoltaic module 20 can be slower and smoother, and damage to the photovoltaic module 20 caused by violent impact can be avoided.
