Technical Field

[0001] The present invention relates to a locking jig for a photovoltaic junction box connector. Background Art

[0002] In the production process of a photovoltaic module junction box, processing operations need to be performed on the cable part of the photovoltaic junction box. Connectors need to be installed at the ends of the cables. Therefore, problems such as connector positioning and matching with the cables need to be solved to prevent shaking and unstable positioning during assembly. However, in existing jigs, there are problems of getting stuck when pushed open and the jig not rebounding in place during use. Summary of the Invention

[0003] In order to overcome the problems encountered in the prior art production process, the purpose of the present invention is to provide a locking jig for a photovoltaic junction box connector with precise positioning.

[0004] To achieve the above purpose, the present invention provides a locking jig for a photovoltaic junction box connector, including a jig positioning base. A positioning hole is provided on the upper surface of the jig positioning base. Base connectors are respectively installed on the left and right sides of the positioning hole. A jig main body is installed above the base connectors. The jig main body is provided with a first channel extending in the Z direction, a second channel extending in the X direction, and a third channel extending in the Y direction. The first channel extends downward from the upper surface of the jig main body into the positioning hole of the jig positioning base. The second channel is located on both sides of the first channel. A pair of side clamping pieces are movably installed in the second channel. Each side clamping piece respectively has an inclined driving groove. Positioning pins are respectively inserted into the driving grooves. Clamping piece upper covers are respectively installed on the side clamping pieces. Positioning grooves extending in the front and back directions are provided on the clamping piece upper covers. The third channel is located below the second channel. A U-shaped push block that can move around the first channel is installed in the third channel. The lower ends of the positioning pins are connected to the two arms of the U-shaped push block, and the other ends are movably located in the positioning grooves. When the U-shaped push block moves into the interior of the jig main body in the Y direction, the side clamping pieces move away from each other to expose the entrance of the first channel. When the U-shaped push block moves out of the interior of the jig main body in the Y direction, the side clamping pieces move closer to each other to lock near the entrance of the first channel.

[0005] Preferably, the first channel includes a connector installation hole provided on the jig main body in the Z direction.

[0006] Preferably, the second channel includes a sliding groove provided on the upper surface of the jig main body in the X direction, and the sliding groove is located on both sides of the connector installation hole.

[0007] Preferably, the third channel includes an empty slot disposed inside the fixture body along the Y direction, and the U-shaped push block is movably disposed in the empty slot.

[0011] Preferably, it includes a step-by-step rotating disk, and a plurality of photovoltaic junction box connector locking fixtures are spaced apart from each other on the circumference of the step-by-step rotating disk. When the step-by-step rotating disk rotates, the U-shaped push blocks of each photovoltaic junction box connector locking fixture are thrown outwards under the action of inertia to lock the photovoltaic junction box connector located in the first channel.

[0012] Preferably, it includes a loading station, and the loading station includes a first unlocking wheel and a first robotic arm. The first unlocking wheel rotates tangentially to the step-by-step rotating disk. When the photovoltaic junction box connector locking fixture on the step-by-step rotating disk rotates to the loading station, when the first unlocking wheel moves the U-shaped push block of the photovoltaic junction box connector locking fixture into the interior of the fixture body, the side clamping pieces move away from each other to expose the entrance of the first channel, and the first robotic arm places the photovoltaic junction box connector into the first channel.

[0013] Preferably, it includes an unloading station, and the unloading station includes a second unlocking wheel and a second robotic arm. The second unlocking wheel rotates tangentially to the step-by-step rotating disk. When the photovoltaic junction box connector locking fixture on the step-by-step rotating disk rotates to the unloading station, when the second unlocking wheel moves the U-shaped push block of the photovoltaic junction box connector locking fixture into the interior of the fixture body, the side clamping pieces move away from each other to expose the entrance of the first channel, and the first robotic arm takes out the photovoltaic junction box connector from the first channel.
