The grabbing assembly has a simple structure and is driven separately. The reliability of the claw hook 6 extending into the hanging hole of the turnover box is high, and the grabbing is stable.

Compared with the prior art, it does not need to be taken out by a robotic arm claw, the structure is simple, and the time consumption is short, thereby improving production efficiency.

[0127] In this embodiment, there are protective plates on both sides of the transition channel 87, so that the photovoltaic module junction box will not fall off after entering the transition channel 87, and the photovoltaic module junction box can be transported by vibrating the transition channel 87.

[0128] In the optional technical solution of the present embodiment, along the conveying direction of the cache conveyor line 88, a first telescopic gear rod 90 and a second telescopic gear rod 91 are sequentially arranged on the cache conveyor line 88, and the first telescopic gear rod 90 and the second telescopic gear rod 91 are both used to block the photovoltaic module junction box on the cache conveyor line 88; a cache area is formed between the first telescopic gear rod 90 and the second telescopic gear rod 91, and the cache area is used to cache the photovoltaic module junction box.

[0129] In this embodiment, the first telescopic gear rod 90 and the second telescopic gear rod 91 are located between the two ends of the cache conveyor line 88, and the first telescopic gear rod 90 is located above the cache conveyor line 88, and the second telescopic gear rod 91 is located on the side of the cache conveyor line 88. A photovoltaic component junction box is cached in the cache area. When the photovoltaic component junction box at the end of the cache conveyor line 88 is taken away, the second telescopic gear rod 91 retracts to release the photovoltaic component junction box in the cache area, and then extends again. The first telescopic gear rod 90 retracts to allow the next photovoltaic component junction box to enter the cache area and then extends to block the subsequent photovoltaic component junction box from entering the cache area. In this way, there is always only one photovoltaic component junction box at the end of the cache conveyor line 88, thereby avoiding the accumulation of photovoltaic component junction boxes at the end of the cache conveyor line 88.

[0130] The optional technical solution of this embodiment also includes a discharge detection sensor 92. The discharge detection sensor 92 is arranged at one end of the buffer conveyor line 88 away from the transition material channel 87 and facing the starting end of the buffer conveyor line 88. The photovoltaic component junction box flowing out of the buffer area gets closer and closer to the discharge detection sensor 92 during the conveying process until the discharge detection sensor 92 senses the photovoltaic component junction box. The buffer area caches the next photovoltaic component junction box to avoid the next photovoltaic component junction box and the previous one being sent out of the buffer area and resulting in accumulation at the end of the buffer conveyor line 88. When the photovoltaic component junction box sensed by the discharge detection sensor 92 is taken away, the buffer area releases the next photovoltaic component junction box. The setting of the discharge detection sensor 92 effectively ensures that there can only be one photovoltaic component junction box at the end of the buffer conveyor line 88.

[0131] The optional technical solution of this embodiment further includes a second in-place detection sensor 93, which is arranged on the buffer conveyor line 88 and between the first telescopic lever 90 and the second telescopic lever 91. The direction of the second in-place detection sensor 93 is perpendicular to the conveying direction of the buffer conveyor line 88. When the second in-place detection sensor 93 detects that the next photovoltaic module junction box enters the buffer area, the first telescopic lever extends to block the next photovoltaic module junction box from continuing to enter, effectively ensuring that there can only be one photovoltaic module junction box in the buffer area.

[0132] The optional technical solution of this embodiment also includes a feed detection sensor 94 , which is arranged at one end of the buffer conveyor line 88 close to the transition channel 87 .

[0133] In this embodiment, the feed detection sensor 94 is located at the starting end of the cache conveyor line 88, and the direction of the feed detection sensor 94 is perpendicular to the conveying direction of the cache conveyor line 88. When there is a photovoltaic component junction box at the starting end of the cache conveyor line 88, the feed detection sensor 94 has a signal. When there is no photovoltaic component junction box at the starting end of the cache conveyor line 88, the feed detection sensor 94 has no signal. At this time, the vibration plate 86 is prompted to continue working and feeding until the vibration plate 86 stops working when the feed detection sensor 94 has a signal. The setting of the feed detection sensor 94 effectively ensures the continuous transportation of the photovoltaic component junction box.

[0134] The optional technical solution of this embodiment further includes relatively arranged guide limit plates 95, which are arranged on both sides of the buffer conveyor line 88 along the conveying direction of the buffer conveyor line 88. The photovoltaic module junction box is conveyed between the relatively arranged guide limit plates 95 to prevent the photovoltaic module junction box from falling on both sides of the buffer conveyor line 88.

[0135] In the optional technical solution of this embodiment, a projection 96 is provided at one end of the guide limit plate 95 away from the transition channel 87, and the projection 96 is located on the opposite side of the guide limit plate 95. The photovoltaic module junction box flowing out of the buffer area is transported to the projection 96 and blocked, so as to prevent the photovoltaic module junction box from falling at the end of the buffer conveying line 88. At the same time, a gap is left between the relative projections 96 for the discharge detection sensor 92 to sense, and the relative projections 96 can also prevent the photovoltaic module junction box from hitting the discharge detection sensor 92.

[0136] The optional technical solution of this embodiment further includes an installation box 97, in which the vibration plate 86, the transition channel 87 and the buffer conveyor line 88 are all arranged, and one end of the buffer conveyor line 88 away from the transition channel 87 extends out of the installation box 97. The installation box 97 effectively protects the vibration plate 86, the transition channel 87 and the buffer conveyor line 88 to prevent external influences on their operation.

[0137] The optional technical solution of this embodiment further includes a material detection sensor 98, which is arranged above the vibration plate 86. The material detection sensor 98 is located in the installation box 97, and detects whether there is a photovoltaic module junction box at the bottom of the vibration plate 86 through the material detection sensor 98. If not, the material is fed to the vibration plate 86.

[0138] A photovoltaic module production system provided in this embodiment includes the above-mentioned automatic loading and installation device for junction boxes. Therefore, the technical advantages and effects achieved by the photovoltaic module production system include the technical advantages and effects achieved by the above-mentioned automatic loading and installation device for junction boxes, which will not be repeated here.
