The belt surfaces of the first conveyor belt 2 and the second conveyor belt 3 are used for horizontally conveying the packaging boxes for photovoltaic cells, and further includes:

[0032] A paste-fixing component, including two side-pressing mechanisms 4 respectively arranged above the first conveyor belt 2 and the second conveyor belt 3, which are used for laterally pushing and fixing the foam material for protecting the battery cells inside the packaging box for packaging the battery cells;

[0033] A limiting mechanism 5, which is arranged on the support frame 1 and the number is two, and is used for limiting the packaging boxes conveyed on the first conveyor belt 2 and the second conveyor belt 3. With such a design, by the side-pressing mechanisms 4 and the limiting mechanisms 5 that are respectively corresponding one by one on the support frame 1, the distance between the two symmetrically distributed limiting crossbars 51 can be adaptively adjusted to meet the limited conveying of packaging boxes of different specifications, prevent the position of the packaging box from shifting during the conveying process, and during the conveying, the side-pressing mechanism 4 can be used to open the open mouth of the packaging box for packaging photovoltaic cells that is being conveyed and paste and fix the foam material around the inner surface of the packaging box to prevent the photovoltaic cells from being damaged by extrusion.

[0034] It should be noted that the style and structure of the packaging box and the foam material paste-fixed inside the packaging box in this embodiment are as Figure 7 shown.

[0035] It should be noted that one side of the foam material is provided with an adhesive surface, and the foam materials can be manually arranged in sequence before entering the side-pressing mechanism 4, so that the foam material with the adhesive surface faces the inner surface of the packaging box.

[0036] In an embodiment, the side-pressing mechanism 4 includes a top block 41, a mounting block 42 and a side-pressing unit 43 which are assembled from top to bottom and arranged on the upper part of the support frame 1.

Contact end blocks 4311 are arranged on the outer sides of the two side plates 431, and several guide rods 4313 arranged at equal intervals are arranged on the side plates 431 between the two contact end blocks 4311; the outside of the guide rod 4313 is arranged in cooperation with the guiding through hole opened on the side part of the mounting block 42. With such a design, by installing the linearly movable side plates 431 in the cavity left by turning and processing at the lower end of the mounting block 42, and the contact end blocks 4311 integrally formed at the outer ends of the outer sides of the side plates 431 and the guide rods 4313 integrally formed in the middle area thereof, the relative distance between the two side plates 431 can be adjusted under the limiting and guiding of the guide rod 4313, and the lateral pushing and pressing operation of the foam material for protecting the photovoltaic cells in the packaging box is realized.

[0037] Preferably, a protective backing plate 4312 with threaded connection is provided at the outer end of the contact end block 4311. With such a design, by rotating the connection column 4321 that is fitted in the internal thread groove machined at the outer end of the contact end block 4311, the distance between the connection column 4321 and the outer end face of the contact end block 4311 can be adjusted in a rotational manner, which can meet the side pressing and inserting of foam materials with different thicknesses into the inner groove of the packaging box, and the use effect is good.

[0039] It should be noted that the cam 432 is designed in an elliptical structure, and the outer surface of the cam 432 is always in close contact with the inner surfaces of the two symmetrical side plates 431.

An internally threaded fixing groove 461 with rotational connection is provided on the outer part of the upper end of the first lead screw 46 and on the end face of the top block 41. With such a design, through the telescopic oil cylinder 44 bolted to the top block 41, and the mounting block 42 is bolted to the movable end of the telescopic oil cylinder 44, and the second guide rod 45 vertically welded to the end face of the mounting block 42 is in guiding and sliding connection with the through opening machined on one side of the top block 41, and the internally threaded fixing groove 461 and the first lead screw 46 assembled in the groove machined on the other side of the top block 41 opposite to the second guide rod 45, and the lower end of the first lead screw 46 extends to the end of the mounting block 42 and is rotatably connected through a bearing, the horizontal position of the side pressing unit 43 can be moved downward or upward under the action of the telescopic oil cylinder 44 to reach different depths inside the packaging box for the side pressing and inserting operation of the foam material. Since the first lead screw 46 is rotatably connected inside the internally threaded fixing groove 461, and the mounting block 42 moves vertically under the drive of the telescopic oil cylinder 44, the rotational movement of the first lead screw 46 can be realized, providing a horizontal driving force.

With such a design, through the second belt pulleys 541 respectively sleeved on the ends of the two second lead screws 53 and the second belt 542 fixedly wound around the second belt pulleys 541, under the action of the motor 543, the generated power drives the rotation of the second lead screw 53 directly connected to the motor 543 on the one hand, and drives the rotation of the other second lead screw 53 through the transmission of the second belt 542 on the other hand, realizing the synchronous movement of the two adjacent U-shaped blocks 52 installed on the support frame 1, and further realizing the movement of the two symmetrical limiting cross bars 51 installed on the support frame 1 in the first conveyor belt 2 area moving towards or away from each other.

[0045] It should be noted that two sections with opposite thread directions are provided on the second lead screw 53, which can synchronously drive the two U-shaped blocks 52 in threaded cooperation with the second lead screw 53 to perform synchronous linear movement.

[0046] It should be noted that the working principle of the limiting mechanism 5 designed on the second conveyor belt 3 is the same as that applied to the first conveyor belt 2.
