[0014] An empty material box discharge layer is set below the empty plate reflow layer.

[0015] A transition frame is provided between the lifting and pushing frame and the unpowered conveying line.

[0016] The transition frame also has a double-layer structure, with the two layers being coplanar with the operating surface and conveying surface of the unpowered conveyor line respectively.

[0044] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0045] like Figures 1-6 As shown, the rotary loading part of this embodiment is equipped with a workbench, including a rotary loading structure and a multi-layer material rack used in conjunction with the rotary loading structure.

[0046] The rotary feeding structure includes:

[0047] The unpowered conveyor line 3 is divided into the operating surface and the conveying surface in the vertical direction.

[0048] The lifting pusher 5 is located at one end of the unpowered conveyor line 3, connecting the conveying surface and the operating surface.

[0049] The gravity return rack 4 is located at the other end of the unpowered conveyor line 3, connecting the operating surface and the conveying surface.

[0050] The multi-layer material rack includes several layers of inclined feeding surfaces, with operating spacing reserved between the feeding surfaces. The operating surface of the unpowered conveyor line 3 is connected to the output direction of the feeding surface.

[0051] The unpowered conveyor line 3 includes an upper workbench 301 and an empty board return layer 302 located in the same vertical plane. The upper workbench 301 is an operating surface, and the empty board return layer 302 is a conveying surface.

[0052] An empty material box discharge layer 303 is provided below the empty plate return layer 302 .

[0053] A transition frame 6 is provided between the lifting and pushing frame 5 and the unpowered conveyor line 3 .

[0054] The transition frame 6 also has a double-layer structure, and the two layers are coplanar with the operating surface and the conveying surface of the unpowered conveyor line 3 respectively.

[0055] The lifting and pushing frame 5 comprises:

[0056] The pusher frame 501 is used as the installation reference.

[0057] The lifting cylinder 502 is located at the bottom of the pusher frame 501.

[0058] The lifting platform 503 is driven by the lifting cylinder 502 , and the two extreme positions of the lifting platform 503 are flush with the operating surface and the conveying surface of the unpowered conveyor line 3 respectively.

[0059] A blocking rod 504 is provided on the side of the lifting platform 503 facing the incoming tooling plate 1, and the blocking rod 504 is formed by extending downward.

[0060] A thrust cylinder 7 is provided on the top of the pusher frame 501 , and the thrust cylinder 7 drives a workpiece push rod 8 .

[0061] Self-gravity reflow rack 4 includes:

[0062] The top of the return frame 401 is provided with a rotating shaft 404 on the side away from the unpowered conveyor line 3,

[0063] The flip platform 402 is connected to the rotating shaft 404.

[0064] The spring 403 is tightened and drawn out from the reflux frame 401 to pull the flip platform 402 to be coplanar with the operating surface.

[0065] The two rotation limit positions of the turning platform 402 are: coplanar with the operating surface and the swing end connected to the conveying surface.

[0066] The force point of the tension spring 403 on the flip platform 402 is located at the rotation shaft 404 .

[0067] The specific structure and working process of the utility model are as follows:

[0068] The assembly platform of the present invention adopts a rotary loading method, which is particularly suitable for conveying and loading flat tooling plates 1 .

[0069] like Figure 6 As shown, a multi-layered material rack 2 is disposed along the longitudinal side of the assembly platform. The multi-layered material rack 2 of the present invention adopts a double-layer structure, with a first loading layer 201 at the top and a second loading layer 202 at the bottom. A mounting bracket 203 for mounting lights and electric fans is provided on the top of the multi-layered material rack 2. The first loading layer 201 and the second loading layer 202 are both inclined, with the rotary loading structure of the present invention being supported at the downwardly inclined ends.

[0070] In order to ensure the smooth sliding of the material box, the inclination degree of the first upper material layer 201 and the second upper material layer 202 requires that there is at least a 10 cm height difference between the high point and the low point of the same upper material layer, so that the material box can slide smoothly along the slope under the action of its own weight.

[0071] As another embodiment of the present invention, the inclined surfaces of the first loading layer 201 and the second loading layer 202 can also be smooth strips or rollers to further reduce friction. For example, for a material box with a non-planar bottom, a roller structure can be preferably used to reduce the probability of the material box being stuck.

[0072] In order to facilitate manual taking of materials from the material box, sufficient operating space is reserved between the material taking ends of the first material loading layer 201 and the second material loading layer 202 .

[0073] like Figure 1-Figure 2 As shown, the purpose of setting up a rotary loading structure is to facilitate the retrieval and processing of materials from the multi-layer material rack 2. The rotary loading structure includes a double-layer unpowered conveyor line 3, which is connected to the discharge side of the multi-layer material rack 2. A self-gravity return frame 4 and a lifting and pushing frame 5 are respectively provided at both ends of the unpowered conveyor line 3. The self-gravity return frame 4 is used to transport the tooling board 1 on the upper workbench 301 of the unpowered conveyor line 3 downward to the empty board return layer 302 on the lower layer of the unpowered conveyor plate; the lifting and pushing frame 5 is used to lift the tooling board 1 on the empty board return layer 302 to the preparation station of the upper workbench 301. An empty material box discharge layer 303 is also provided to the west of the double-layer unpowered conveyor line 3, and a dedicated material handler recycles the empty material boxes.

[0074] The assembly operation is performed on the upper workbench 301 , and the lower empty board reflow layer 302 serves as a reflow layer for the tooling board 1 .

[0075] like Figure 3 As shown, the self-gravity reflow rack 4 includes a reflow rack body 401, and the top of the reflow rack body 401 is rotatably connected to a flip platform 402. One side of the flip platform 402 is connected to the reflow rack body 401 by a tensioned spring 403, so that the initial state of the flip platform 402 is horizontal and coplanar with the upper workbench 301 of the unpowered conveyor line 3.

[0076] When the tooling board 1 is pushed onto the flipping platform 402, the flipping platform 402 is affected by gravity and rotates around the rotating shaft 404. At this time, the tensioning spring 403 is stretched, and the flipping platform 402 tilts toward the empty board return layer 302. The tooling board 1 slides along the inclined surface onto the empty board return layer 302; the pressure on the flipping platform 402 is removed, and it is reset under the action of the tensioning spring 403.

[0077] There is also a transition frame 6 between the lifting and pushing frame 5 and the unpowered conveyor line 3.

[0078] like Figure 4 and Figure 5 As shown, the lifting and pushing rack 5 includes a pushing rack body 501, and a lifting cylinder 502 is provided at the bottom of the pushing rack body 501. The lifting cylinder 502 lifts the lifting platform 503. The two extreme positions of the lifting platform 503 are respectively coplanar with the empty board return layer 302 and coplanar with the upper workbench 301. When the lifting platform is rising, in order to prevent subsequent empty boards from continuing to rush forward, a blocking rod 504 is provided on the side of the lifting platform 503 facing the incoming empty boards. The blocking rod 504 extends downward from the side of the lifting platform 503. When the lifting platform 503 is in a low position, the empty boards can be transported normally; when the lifting platform 503 rises to a high position, the blocking rod 504 intercepts the feeding direction of the empty boards.

[0079] A thrust cylinder 7 is also provided on the top of the pusher frame 501, and is equipped with a workpiece push rod 8. When the tooling plate 1 is loaded with materials and lifted to the highest position by the lifting cylinder 502, the thrust cylinder 7 is activated, and the workpiece push rod 8 pushes the fully loaded tooling plate 1 to the upper layer of the transition frame 6, where it is ready for use by employees.

[0080] At this point, the entire rotary loading structure forms a loop circulation in the vertical direction. The rotary loading structure of the utility model can be used in conjunction with multiple working conditions. The advantage is that the tooling plates 1 in each link can be effectively distributed without the need for a conveyor belt power source, and there will be no overlap.

[0081] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
