Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic junction box production, in particular to a high-efficiency corona treatment device for photovoltaic junction boxes. Background Art

[0002] At present, in the production process of photovoltaic junction boxes, it is usually necessary to perform corona pretreatment on the junction boxes. The reason is that in actual production, the inside of the junction box usually involves a variety of materials, such as metal terminals, wires, and various insulating plastic parts.

[0003] Corona treatment is mainly used in the following aspects:

[0004] a. Improve adhesion: Corona treatment of the interior of certain insulating materials or the parts in contact with metal can increase their surface energy and roughness, allowing the potting glue or adhesive to adhere better to its surface, thereby enhancing the stability of the connection between the components inside the junction box and preventing electrical insulation failure caused by loose potting.

[0005] b. Prevent corona discharge: For electrical equipment operating under high voltage conditions, if the insulation surface is defective or the surface smoothness is too high, it may cause the local electric field strength to increase and corona discharge to occur, which will not only accelerate material aging, but also generate heat and even cause fire. Improving the surface state of the insulating material through corona treatment helps to reduce the corona starting voltage and reduce the possibility of corona discharge.

[0006] c. Improve weather resistance: Photovoltaic junction boxes need to work in outdoor environments for a long time. The surface after corona treatment is more conducive to moisture and corrosion resistance, extending the service life.

[0007] However, the traditional corona treatment method is to place the junction boxes one by one in the slot of the rotating chain for treatment. This method has problems such as low work efficiency, high labor intensity, and limited production capacity. Utility Model Content

[0008] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, a high-efficiency corona treatment device for a photovoltaic junction box is provided.

[0009] The utility model solves the technical problem by adopting a technical solution: a photovoltaic junction box high-efficiency corona treatment device, comprising a frame, wherein the frame is provided with a grooved track, a transmission device and a corona device.

[0010] The grooved track includes an array of tracks, each track includes stoppers on both sides and a through slot for placing a photovoltaic junction box between the stoppers on both sides, the stoppers are fixedly suspended above the transmission device through a connecting plate, a long strip screw hole is provided on the connecting plate, and a bolt passing through the long strip screw hole fixes the stopper to the lower end of the connecting plate, and the long strip screw hole on the connecting plate makes it easier to adjust the distance between the stoppers, and the width of the through slot can be flexibly adjusted according to the specifications of the photovoltaic junction box, ensuring that the junction box can be stably placed in the track through slot;

[0011] The photovoltaic junction box is placed above the transmission device and moves in the through groove of the groove track as the transmission device moves.

[0012] The corona device includes a corona gun located just above the through slot of the slotted track and a fixing member fixing the corona gun on the frame. Each through slot of a set of tracks is equipped with a corona gun, and the corona gun is set on the track running path. When the junction box passes the position of the corona gun, the corona treatment process is automatically completed.

[0013] The parallel operation of the array tracks and the transmission device cooperate with the transmission to achieve continuous and rapid junction box transportation, effectively shortening the processing interval time of a single junction box and greatly improving the production capacity of the corona treatment stage.

[0014] Furthermore, the transmission device adopts a belt with a power transmission device, and the belt adopts a whole-piece structure located below the groove track. One belt can drive multiple groups of photovoltaic junction boxes between the grooves at the same time, which improves efficiency without increasing the transmission cost.

[0015] Furthermore, the two ends of the connecting plate are fixed on the two side edges of the frame, and a pad is provided between the connecting plate and the frame. The pad ensures that there is a certain gap between the lower end surface of the limiter after being fixed and the upper end surface of the transmission device. During the transmission of the photovoltaic junction box, the limiter and the transmission device will not contact each other.

[0016] Furthermore, the connection plates are provided at intervals of 2-4 to ensure the connection stability between the limiter and the connection plate.

[0017] The beneficial effects of the utility model are as follows: through the parallel operation of the array tracks, the transmission device cooperates with the transmission to realize continuous and rapid junction box transportation, effectively shortening the processing interval time of a single junction box, and greatly improving the production capacity of the corona treatment stage; through the long strip screw holes on the connecting plate, the distance adjustment between the limiters is simpler, and the width of the through groove can be flexibly adjusted according to the specifications of the photovoltaic junction box, ensuring that the junction box can be stably placed in the track through groove.
