The entire device has a compact structure, diverse functions and excellent use effect.

[0019] The present invention further improves the design of the material receiving frame and the material pressing frame. After the photovoltaic panels are received in sequence, when the material pressing frame and the material receiving frame are close to each other to clamp the photovoltaic panels up and down, the inclined extrusion block in the material pressing frame or the material receiving frame above it will enter the socket to squeeze the inclined movable block, so that it is pushed toward the inside of the material receiving frame and overcomes the force of the spring. Then, the two sides of the photovoltaic panel on the roller are clamped and centered by the action of the two clamping strips, which effectively prevents the photovoltaic panel from sliding and colliding due to insufficient upper and lower clamping force during the subsequent 90° flipping process, greatly reducing the probability of accidental damage during the transportation of the photovoltaic panel.

A second slide rail 404 is provided on the top wall of the transmission case 401, and a rack 405 is slidably connected to the second slide rail 404. Then, a first cylinder 406 is provided on one side of the transmission case 401. Of course, the first cylinder 406 can also be replaced by other driving components with telescopic functions, and the end of the piston rod of the first cylinder 406 is connected to the rack 405.

[0034] Reference Attachment Figure 5 and attached Figure 6 The material receiving unit 3 includes a frame 301 fixedly connected to a rotating shaft 407. A strip-shaped opening 302 is formed on both sides of the upper end of the frame. A rectangular block 300 is slidably disposed in each strip-shaped opening 302. A second screw rod 303 is rotatably connected between the built-in bearings of the two rectangular blocks 300, and the external threads at both ends of the second screw rod 303 are arranged in opposite directions.

A moving block 305 is threadedly connected to each end of the second screw rod 303, and a vertical downward-pointing lever 306 is connected to the lower surface of each moving block 305.

[0035] A plurality of receiving frames 307 are evenly spaced above and below the opening of the frame 301, and a row of rollers 308 are rotatably mounted in the receiving frames 307. A pressing frame 309 is also evenly spaced above the uppermost receiving frame 307, and a row of pressing rollers 310 are rotatably mounted in the pressing frame 309. Vertical chutes are provided on both sides of the opening of the frame 301, and sliders 311 matching the vertical chutes are provided on both the receiving frame 307 and the pressing frame 309. The slider 311 on one of the receiving frames 307 is fixedly welded to the vertical chute, and the sliders 311 on the other receiving frames 307 and the pressing frame 309 are all slidably mounted along the vertical chute.

[0036] The second cylinder 312 is fixedly installed at the upper end of the frame 301, which can be replaced by other driving members with telescopic function, and the lower end of the piston rod of the second cylinder 312 is connected with the pressing frame 309. Then, the forked telescopic frames 313 are arranged on both sides of all the receiving frames 307 and the pressing frame 309, and each intersection node of the forked telescopic frame 313 is connected with the side end of the corresponding receiving frame 307 or the pressing frame 309. When the second cylinder 312 is elongated or shortened, the pressing frame 309 can be moved up and down along the vertical sliding groove, and then all the receiving frames 307 and the pressing frame 309 can be synchronously moved towards or away from the receiving frame 307 fixed on the vertical sliding groove under the action of the forked telescopic frame 313.

[0037] Finally, a notch is formed at one end of each receiving frame 307 close to the frame 301, and the mirror-symmetrical forked pushing frame 314 is rotatably connected in the notch, and the forked pushing frame 314 is arranged above the corresponding supporting roller 308, and then the pushing wheel 315 is connected at the end of the forked pushing frame 314 extending into the receiving frame 307, and the round hole 316 for passing the pushing rod 306 is formed at the end of the forked pushing frame 314 extending out of the receiving frame 307.

[0038] In the use process of the photovoltaic panel transfer device disclosed in Embodiment 1, the operating personnel pushes it to the position of the tail end of the conveying belt on the photovoltaic production line and connects it, and then the lowermost receiving frame 307 in the receiving unit 3 is kept at the same horizontal height as the tail end of the conveying belt through the lifting mechanism.

[0039] Whenever the supporting roller in the receiving frame 307 receives a photovoltaic panel, the servo motor in the lifting mechanism can control it to descend by a certain distance so that the receiving frame 307 above receives the next photovoltaic panel, and when all the receiving frames 307 receive a photovoltaic panel, the piston rod of the second cylinder 312 is directly controlled to be elongated, and then all the receiving frames 307 and the pressing frame 309 are synchronously moved towards the receiving frame 307 fixed on the vertical sliding groove under the action of the forked telescopic frame 313, so that the photovoltaic panel is pressed and clamped up and down by the two supporting rollers 308 or the supporting roller and the pressing frame 309.

[0040] Then, the first cylinder 406 is started to move the rack 405 along the second slide rail 404, and the receiving unit 3 is rotated 90° through the meshing between the rack 405 and the gear 408. After the receiving unit 3 is rotated, the worker pushes the photovoltaic panel to be aligned with the insertion position of the transfer tool box or the packaging box, and then aligns the vertical photovoltaic panel with the insertion slot position of the transfer tool box or the packaging box up and down through the lifting mechanism. After the alignment, the second motor 304 is started to rotate the second lead screw 303, and the two shift rods 306 are synchronously moved towards each other through the action between the second lead screw 303 and the moving block 305. Then, the outer ends of the fork type pushing frame 314 in all the receiving frames 307 are close to each other under the action of the shift rod 306, so that the pushing wheels 315 at the inner ends of the fork type pushing frame 314 are also close to each other, so as to push the clamped photovoltaic panel into the insertion slot of the transfer tool box or the packaging box (see Figure 8). Figure 8 The transfer packaging process is completed. Embodiment 2

[0041] Embodiment 2 discloses a photovoltaic panel transfer device which is improved on the basis of embodiment 1, and the same parts as those of embodiment 1 will not be described again.

[0042] Referring to Figure 8, Figure 7 In this embodiment 2, the insertion hole 317 is formed on the upper surface of the two ends of each receiving frame 307, and the through hole 318 passing through the lower end of the insertion hole 317 is formed on the side surface of the two ends of the receiving frame 307. The inclined movable block 319 is arranged in the through hole 318, the clamping strip 320 is connected to the outer end of the inclined movable block 319 extending into the inside of the receiving frame 307, and the spring 321 is connected between the clamping strip 320 and the side surface of the two ends of the receiving frame 307.

[0043] In addition, the inclined extrusion block 322 aligned with the insertion hole 317 is connected to the lower surface of the two ends of the receiving frame 307 and the pressing frame 309, and the inclined surface of the inclined extrusion block 322 cooperates with the inclined surface of the inclined movable block 319, so that the inclined movable block 319 can be pushed into the inside of the receiving frame 307 and overcome the force of the spring 321 during the downward extrusion of the inclined extrusion block 322. Then, the photovoltaic panel on the supporting roller 308 is clamped in the middle through the action of the two clamping strips 320, which effectively prevents the side sliding and impact phenomenon of the photovoltaic panel during the subsequent 90° rotation process due to the ineffective clamping of the photovoltaic panel by the upper and lower supporting rollers 308 or the pressing frame 309.

[0044] The above is only a preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
