[0002] In the production process of photovoltaic modules, four-wire testing is an essential link. The four-wire testing is carried out by using a photovoltaic adapter testing device, which can effectively measure parameters such as the voltage, current and power of the photovoltaic module to ensure that the performance of the module meets the design requirements. In order to achieve efficient and accurate four-wire testing, corresponding tooling is required to complete the testing and realize the reflux of the photovoltaic adapter testing device located at the end to the testing front end for repeated use.

[0018] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0019] A hanging type return tooling for a photovoltaic adapter testing device, in combination with Figures 1 to 2 as shown, includes a rail beam 1 and a rotary track 2. Among them, the rail beam 1 is erected on a support surface; the rotary track 2 is combined with the layout of the on-site return line, and the rotary track 2 is erected through the rail beam 1.

[0020] Inside the rotary track 2, an active sprocket, a driven sprocket and a chain are rotatably arranged. Specifically, there is one active sprocket, which is connected to a motor. The motor is arranged outside the rotary track 2, and the rotating shaft of the motor is connected to the active sprocket through a transmission component. The transmission component is a prior art and will not be defined and described herein; there are several driven sprockets; the chain is sleeved on the active sprocket and the driven sprockets and meshes with the active sprocket and the driven sprockets. When the rotating shaft of the motor rotates, it drives the active sprocket to rotate. The rotation of the active sprocket drives the driven sprockets to rotate synchronously. The synchronous rotation of the active sprocket and the driven sprockets drives the chain to rotate synchronously inside the rotary track 2.

[0021] A number of hooks 4 are arranged at intervals on the chain. The hooks 4 are hinged to the chain and are located below the rotary track 2. The hooks 4 are used to hook the photovoltaic adapter testing device. Specifically, a notch is provided at the bottom of the rotary track 2 along the circumferential direction; a number of hinge members 3 are arranged at intervals on the chain. The top of each hinge member 3 is hinged to the chain, and the bottom end of each hinge member 3 passes through the notch and is correspondingly hinged to each hook 4 one by one.

[0022] As Figure 3 shown, the tooling further includes hanging members 5. There are at least two hanging members 5, and they are arranged at both ends of the photovoltaic adapter testing device. The hanging members 5 are used to hang the photovoltaic adapter testing device on at least two hooks 4, so as to hang the photovoltaic adapter testing device on the chain in the rotary track 2, and then move with the rotation of the chain to achieve cyclic operation.

[0023] Specifically, the hanging member 5 includes an upper plate body 51 and a lower plate body 52. Among them, the upper plate body 51 is semi-circular; the lower plate body 52 is rectangular. The top end of the lower plate body 52 is connected to the bottom end of the ring opening of the upper plate body 51, and the lower plate body 52 and the upper plate body 51 are integrally formed. Fixing holes 54 are provided on the lower plate body 52. There are at least two fixing holes 54, and they are arranged side by side. The fixing holes 54 are used to fix the hanging member 5 on the photovoltaic adapter testing device; the ring opening of the upper plate body 51 and the lower plate body 52 form a hook opening 53, and the hook opening 53 is used for the hook 4 to hook.

[0024] When the utility model is in use, the artificial picking and placing of the photovoltaic adapter testing device is realized through the hanging member 5 and the hook 4; during the transmission process, the hook 4 reciprocates in the hook opening 53, which can effectively prevent the photovoltaic adapter testing device from falling; and cyclic operation is carried out through the rotary track 2, the motor, the active sprocket, the driven sprockets and the chain.
