Description

TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaic panel production, in particular to a junction box welding positioning detection device. BACKGROUND

[0002] The junction box is a connecting device between the solar cell array composed of solar cell components and the solar charging control device. Its main function is to connect and protect the solar photovoltaic module, connect the power generated by the solar cell with the external line, and conduct the current generated by the photovoltaic module.

[0003] In the production of photovoltaic panels, the junction box is usually automatically welded on the photovoltaic panel by a welding machine, but the subsequent detection work mostly adopts manual checking method, which consumes a lot of manpower and has low efficiency. SUMMARY

[0004] The purpose of the present application is to provide a junction box welding positioning detection device for reducing labor consumption and improving the detection efficiency of the junction box welding quality.

[0005] The junction box welding positioning detection device provided by the present application adopts the following technical solution:

[0006] A junction box welding positioning detection device, comprising a conveying frame, a feeding conveyor belt is arranged on the conveying frame, one end of the feeding conveyor belt is provided with a detection mechanism, the detection mechanism comprises a screening assembly connected with the feeding conveyor belt, and a detection camera for detecting the junction box is arranged above the screening assembly.

[0007] By adopting the above technical solution, after the junction box is welded on the photovoltaic panel, the photovoltaic panel and the junction box are conveyed to the screening assembly by the feeding conveyor belt, and the detection camera takes a picture of the junction box on the photovoltaic panel for detection. The welding quality is identified through the picture. If the welding quality is qualified, the photovoltaic panel is conveyed to the next step; if the welding quality is unqualified, the photovoltaic panel is screened to another place by the screening assembly for re-welding work of the junction box and the photovoltaic panel, thereby reducing the labor intensity and improving the detection efficiency.

[0008] Optionally, the screening assembly comprises a conveying frame close to the end of the feeding conveyor belt, an outfeed conveyor belt is arranged on the conveying frame, support rollers parallel to the outfeed conveyor belt are arranged on both sides of the outfeed conveyor belt, and a lifting member is arranged below the support rollers.

[0009] By adopting the above technical scheme, when the photovoltaic panel is close to the screening assembly, the lifting piece lifts the height of the supporting roller, so that the supporting roller is higher than the discharging conveying belt and is flush with the feeding conveying belt, thereby receiving the photovoltaic panel; when the detection camera detects that the welding quality is unqualified, under the action of the lifting piece, one supporting roller is lifted and the other supporting roller is lowered, so that the photovoltaic panel is inclined and moves away from the discharging conveying belt, thereby facilitating the repair welding work; when the detection camera detects that the welding quality is qualified, both supporting rollers are lowered, so that the photovoltaic panel is overlapped on the discharging conveying belt, and the photovoltaic panel can be conveyed to the next step, thereby quickly completing the detection and screening work and improving the work efficiency.

[0010] Optionally, the discharging conveying belt is horizontally and vertically opposite to the feeding conveying belt, a baffle is arranged on the side of the discharging conveying belt away from the feeding conveying belt, the baffle is rotationally connected with the conveying frame, a connecting rod is hingedly connected to the end of the supporting roller close to the baffle, and the connecting rod is hingedly connected with the upper end of the baffle.

[0011] By adopting the above technical scheme, when the photovoltaic panel is above the supporting roller, the baffle abuts against the side wall of the photovoltaic panel, for limiting the position of the photovoltaic panel; when it is necessary to screen the unqualified photovoltaic panel, one supporting roller is lifted and the other supporting roller is lowered, the lowered supporting roller drives the baffle to rotate through the connecting rod, so that the photovoltaic panel can pass below the baffle and slide on the inclined surface formed by the two supporting rollers, thereby completing the screening work.

[0012] Optionally, the feeding conveying belt is provided with a centering mechanism on both sides, the centering mechanism comprises positioning shafts arranged on both sides of the feeding conveying belt, and moving blocks are rotationally connected to the positioning shafts; the conveying frame is further provided with a driving assembly for driving the two moving blocks to move towards each other.

[0013] By adopting the above technical scheme, when the feeding conveying belt conveys the photovoltaic panel, the driving assembly drives the two positioning shafts to move towards each other, so as to position the photovoltaic panel on the center line, thereby quickly adjusting the position of the photovoltaic panel, facilitating the welding work of the photovoltaic panel and the junction box, improving the welding quality, and enabling the welded junction box to accurately reach below the detection camera to complete the detection work.

[0014] Optionally, the driving assembly comprises driving blocks arranged on the moving blocks, the driving blocks are slidingly connected with the conveying frame, the driving assembly further comprises a bidirectional screw rod for simultaneously screwing two opposite driving blocks, the bidirectional screw rod is rotationally connected with the conveying frame, a worm wheel is arranged on the bidirectional screw rod, and a worm is engaged with the worm wheel in parallel to the feeding conveying belt, and the worm is rotationally connected with the conveying frame.

[0015] By adopting the above technical solution, the worm gear is rotated, which drives the bidirectional lead screw to rotate through the worm wheel. The drive blocks on the bidirectional lead screw move towards each other, thereby driving the two moving blocks to move, which in turn brings the two positioning shafts closer to each other, thereby quickly adjusting the orientation of the photovoltaic panel.

[0016] Optionally, a drive sleeve is threaded onto the worm gear with ball bearings, and a support block that moves vertically is slidably connected to the drive sleeve. A guide rail is provided on the conveyor frame, and the support block is slidably connected to the guide rail. The guide rail gradually descends along the conveying direction of the feed conveyor belt, and a return spring is provided between the drive sleeve and the conveyor frame.

[0017] By adopting the above technical solution, during the process of the photovoltaic panel being conveyed by the feeding conveyor belt, the photovoltaic panel abuts against the fixed push support block and moves. At the same time, the support block moves along the guide rail and slides downward under the guidance of the guide rail until the support block is located below the photovoltaic panel. During the process of the support block being pushed by the photovoltaic panel, the support block drives the worm gear to rotate, thereby adjusting the position of the photovoltaic panel by the two positioning shafts. After the photovoltaic panel passes over and disengages from the support block, the return spring pushes the drive sleeve to return to its original position, thereby making the two positioning shafts move away from each other, preparing for the next adjustment of the photovoltaic panel.

[0018] Optionally, the driving block and the moving block are slidably connected, and a buffer spring connecting the two is provided between the driving block and the moving block.

[0019] By adopting the above technical solution, the driving block and the moving block are slidably connected to each other, which reduces the impact on the photovoltaic panel when the positioning shaft adjusts the position of the photovoltaic panel, thereby providing protection for the photovoltaic panel.

[0020] Optionally, guide plates are provided on both sides of the positioning shaft, the guide plates are disposed on the drive block, and the end of the guide plate away from the positioning shaft is away from the feeding conveyor belt.

[0021] By adopting the above technical solution, the photovoltaic panel first contacts the guide plate before approaching the positioning shaft, and under the guidance of the guide plate, it abuts against the side of the positioning shaft near the feeding conveyor belt, thereby reducing the possibility that the guide plate will be obstructed by the positioning shaft and cannot be conveyed.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The inspection camera can quickly inspect the welding quality of junction boxes and photovoltaic panels, thereby reducing manual labor intensity and improving inspection efficiency;

[0024] 2. The centering mechanism can automatically adjust the orientation of the photovoltaic panel during its movement, ensuring accurate welding and inspection positions and improving welding quality. Attached Figure Description
