AI Technical Summary
During the production of photovoltaic modules, when a junction box falls onto the conveyor belt, the interface side may face downwards, causing subsequent installation work to be disrupted, increasing labor costs and limiting output.
Design a junction box falling correction device, including a slide rail and a baffle. The slide rail is set above the conveyor belt, and the junction box moves along its curved surface to keep the interface face upward. The baffle slows down the movement and prevents it from flipping over.
Ensure that the junction box interface face is always upward to reduce labor costs, improve production efficiency, and increase daily output.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of photovoltaic junction box production equipment, and in particular to a junction box drop correction device. Background Technology
[0002] The junction boxes used in photovoltaic modules have interfaces on one side. During production, the diodes are moved onto the conveyor belt by a robotic arm. Because there is a certain height between the junction box and the conveyor belt, after the junction box falls onto the conveyor belt, some of the interface surfaces of the junction box come into contact with the conveyor belt. In order for the subsequent junction box installation work to proceed normally, additional personnel need to be arranged to guard one side of the conveyor belt and flip the junction boxes with the interface surfaces facing down after they fall. This not only increases the factory's labor costs, but also limits the daily output of the overall production line. Utility Model Content
[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a junction box drop correction device that prevents junction boxes from flipping over (i.e., the interface side facing down) when they fall onto the conveyor belt, ensuring the normal progress of subsequent junction box installation operations, reducing labor costs while increasing the daily output of the production line.
[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0005] A junction box falling correction device includes a device body disposed on a transmission belt. The device body includes a slide rail plate disposed directly above the transmission belt, and the curved surface of the slide rail plate faces the opposite direction of the movement of the transmission belt.
[0006] In a preferred embodiment, the present invention can be further configured such that: a first fixing plate is provided on both sides of the conveyor belt, and the slide rail plate is fixedly disposed between the two first fixing plates.
[0007] In a preferred embodiment, the present invention can be further configured such that a connecting plate is provided between the two first fixing plates, and a baffle is hinged to the bottom of the connecting plate, the baffle facing the curved surface of the slide rail plate.
[0008] In a preferred embodiment, the present invention can be further configured such that the distance between the slide rail plate and the baffle is 8 cm to 10 cm.
[0009] In a preferred embodiment, the present invention can be further configured such that the slope of the curved surface in the slide rail plate is 14-16 degrees.
[0010] In a preferred embodiment, the present invention can be further configured such that the height of the slide rail plate is 40 mm to 50 mm.
[0011] In summary, this utility model has at least one of the following beneficial technical effects:
[0012] 1. By installing a slide rail on the conveyor belt, the junction box falling from the shelf moves along the curved surface of the slide rail onto the conveyor belt, avoiding the junction box from flipping over (i.e., the interface side facing down) when it falls onto the conveyor belt. This ensures that the subsequent junction box installation work can proceed normally, reducing labor costs while increasing the daily output of the production line.
[0013] 2. By setting a baffle, which is movably connected to the connecting plate, the baffle has the function of slowing down the movement of the junction box. Attached Figure Description
[0014] Figure 1 This is a schematic diagram of the overall structure of this embodiment.
[0015] In the figure, 1 is the device body; 11 is the slide rail plate; 2 is the first fixing plate; 3 is the connecting plate; and 31 is the baffle. Detailed Implementation
[0016] The present invention will be further described in detail below with reference to the accompanying drawings.
[0017] Example:
[0018] Reference Figure 1 This utility model discloses a junction box falling correction device, including a device body 1 mounted on a conveyor belt. A rack holding several junction boxes is placed on one side of the conveyor belt. The junction boxes on the rack all face the same direction.
[0019] The device body 1 includes a slide rail plate 11, which is positioned directly above the conveyor belt.
[0020] A first fixing plate 2 is provided on both sides of the conveyor belt, and a slide rail 11 is fixedly installed between the two first fixing plates 2. The curved surface of the slide rail 11 faces the opposite direction of the conveyor belt movement.
[0021] The slope of the curved surface in the slide rail plate 11 is 14-16 degrees. In this embodiment, the slope of the curved surface in the slide rail plate 11 is 15 degrees.
[0022] The height of the slide rail plate 11 is 40 mm to 50 mm. In this embodiment, the height of the slide rail plate 11 is 45 mm.
[0023] As the robotic arm removes the junction box from the frame, the junction box contacts the curved surface of the slide rail plate 11 and moves downward along the curved surface.
[0024] The junction box lands smoothly on the conveyor belt, ensuring that the front of the junction box, i.e., the side with the interfaces inside, faces upwards.
[0025] The conveyor belt delivers the junction box to the appropriate position.
[0026] A connecting plate 3 is also provided between the two first fixed plates 2. A baffle 31 is hinged to the bottom of the connecting plate 3, and the baffle 31 faces the curved surface of the slide rail plate 11. When the junction box that punches out of the slide rail plate 11 touches the baffle 31, the baffle 31 slows down the movement of the junction box. The distance between the slide rail plate 11 and the baffle 31 is 8 cm to 10 cm. In this embodiment, the distance between the slide rail plate 11 and the baffle 31 is 9 cm.
[0027] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
