[0034] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention application are described in detail below in conjunction with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0035] In the description of the present invention, it should be clarified that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, but are not necessarily used to describe a specific order or sequence; the terms "vertical", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "horizontal", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention, and do not mean that the referred device or element must have a specific direction or position, and therefore cannot be understood as a limitation on the present invention.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] This embodiment provides a layered flipping mechanism, such as Figure 1-Figure 4 As shown, the layered flipping mechanism includes a fixed frame 1, a layered component 2 and a flipping component 3, the layered component 2 and the flipping component 3 are both arranged on the fixed frame 1, and the flipping component 3 is located downstream of the layered component 2; the material is layered at the layered component 2 and pushed to the flipping component 3, and flipped at the flipping component 3.

[0038] Specifically, the fixed frame 1 includes a plurality of horizontal rods and a plurality of vertical rods, which are connected to each other to form a fixed frame. The fixed frame 1 has a space inside, which is used for the operation of the layering component 2 and the flipping component 3, and is also used to accommodate materials. The layering component 2 is arranged in the fixed frame 1, and its output end can push the material to achieve layering. The flipping component 3 is arranged in the fixed frame 1, which can realize the flipping of the material.

[0039] After adopting the layered flipping mechanism provided in this embodiment, when the incoming material is a double-layer structure, for example, when the incoming material is a double-layer condenser, the layered component 2 can push the condenser of the upper layer to the flipping component 3, and the condenser is now located on the fixed frame 1, and then the flipping component 3 works to flip it and then enter the next process. The condenser located at the lower layer directly enters the next process, or directly enters the next process after passing through the flipping component 3.

[0040] It can be seen that the layered flipping mechanism provided in this embodiment realizes the automatic layering of the upper and lower layers of materials, and can flip the layered materials. Compared with the traditional manual layering flipping, the automatic layering flipping of this embodiment has obviously higher reliability, and can solve the technical problems of high labor intensity and low efficiency in the traditional manual layering flipping of materials.

[0041] In a specific embodiment, Figure 5-Figure 8 As shown, the layered component 2 includes a first movable unit 21, a second movable unit 22 and a push plate 23, the second movable unit 22 is connected to the push plate 23 for driving the push plate 23 to move along the second direction, and the first movable unit 21 is connected to the second movable unit 22 for driving the push plate 23 to move along the first direction through the second movable unit 22.

[0042] In this embodiment, the first moving unit 21 is used to realize the movement of the push plate 23 in the vertical direction, and the second moving unit 22 is used to realize the movement of the push plate 23 in the horizontal direction. The first moving unit 21 and the second moving unit 22 can control the position of the push plate 23 after being combined, so that it can accurately act on the material that needs to be layered. For example, when the incoming material is a double-layer condenser, the first moving unit 21 first drives the second moving unit 22 and the push plate 23 to move in the vertical direction, so that the height of the push plate 23 is just located at the edge of the upper condenser, and then the second moving unit 22 moves, applying a forward force to the push plate 23, so that the push plate 23 pushes the upper condenser to move to the flip assembly 3. After completing the current action, the first moving unit 21 and the second moving unit 22 return to the initial position to prepare for the subsequent layering.

[0043] In a specific embodiment, the first moving unit 21 includes a first telescopic cylinder 211, a lifting fixed plate 212 and a cylinder fixed plate 213, wherein the cylinder fixed plate 213 is fixed to the fixed frame 1, and the first telescopic cylinder 211 is arranged on the cylinder fixed plate 213 and its telescopic end passes through the cylinder fixed plate 213 and is connected to the lifting fixed plate 212. The first telescopic cylinder 211 is arranged vertically, and the lifting fixed plate 212 and the cylinder fixed plate 213 are both plate-shaped structures, which are arranged horizontally, and the lifting fixed plate 212 is located below the cylinder fixed plate 213. In a specific structure, the cylinder fixed plate 213 is fixed to the fixed frame 1, the main body of the first telescopic cylinder 211 is fixed above the cylinder fixed plate 213, and the telescopic end of the first telescopic cylinder 211 passes through the cylinder fixed plate 213 and is connected to the lifting fixed plate 212.

[0044] The main function of the first mobile unit 21 is to realize the vertical movement of the push plate 23. In this embodiment, the second mobile unit 22 is connected to the lifting and fixing plate 212. In this way, when the first telescopic cylinder 211 is extended, its telescopic end can push the lifting and fixing plate 212 to move downward, thereby causing the second mobile unit 22 to move downward, and because the push plate 23 is connected to the second mobile unit 22, the push plate 23 moves downward. Conversely, when the first telescopic cylinder 211 is retracted, it can cause the push plate 23 to move upward through the second mobile unit 22.

[0045] In this embodiment, the first telescopic cylinder 211 is composed of two or more piston cylinders, and the inner hole of the piston rod of the previous piston cylinder is the cylinder barrel of the next piston cylinder. When the air pressure acts, the outermost large-diameter cylinder begins to extend outward with the lowest oil pressure. When it reaches the end of the stroke, the next smaller-diameter cylinder begins to extend outward, and so on, until the last-stage cylinder with the smallest diameter is fully extended. This step-by-step extension method enables the telescopic cylinder to obtain a longer working stroke in a limited space. On the contrary, when it needs to be retracted, the air pressure acts on the piston rod to gradually retract it, and finally all levels of cylinders return to the initial position to maintain a small structural size.

[0046] In addition, in a specific embodiment, the first moving unit 21 further includes a first guide rod 214, and two first guide rods 214 are provided. The two first guide rods 214 pass through the cylinder fixing plate 213 from both sides of the first telescopic cylinder 211 and are fixed to the lifting fixing plate 212. In other words, the first guide rod 214 is similar to the first telescopic cylinder 211, and its main part is located above the cylinder fixing plate 213, and the remaining part passes through the cylinder fixing plate 213 and is fixed to the lifting fixing plate 212. Among them, the first telescopic cylinder 211 is used to provide driving force for the lifting fixing plate 212, and the two first guide rods 214 are used to ensure the stability of the lifting fixing plate 212 when it moves up and down, so as to avoid the lifting fixing plate 212 from tilting due to the asynchronous movement of the two sides, which affects the stratification of materials.

[0047] In a specific embodiment, the second moving unit 22 includes a second telescopic cylinder 221, which is fixed on the lifting fixed plate 212 and its telescopic end is connected to the push plate 23. The second telescopic cylinder 221 is horizontally arranged, and its telescopic end acts on the push plate 23. When it is extended, its telescopic end can push the push plate 23 to move in a first direction, and when it is retracted, its telescopic end can make the push plate 23 move in a second direction, wherein the first direction and the second direction are two opposite directions.

[0048] In a specific embodiment, the second moving unit 22 further includes a second guide rod 222, two second guide rods 222 are provided, and the two second guide rods 222 are respectively located on both sides of the second telescopic cylinder 221, and the ends thereof are fixed on the push plate 23. Similar to the first guide rod 214, the second guide rod 222 can ensure the smooth movement of the push plate 23 in the horizontal direction, and avoid the influence of the asynchronous positions of the two sides thereof on the stratification of the material, for example, one side of the material has been pushed to the flip assembly 3, while the other side has not yet reached the flip assembly 3.

[0049] In a specific embodiment, Figure 9-11 As shown, the flipping assembly 3 includes a lifting unit 31, a clamping unit 32 and a rotating unit 33, the lifting unit 31 is connected to the clamping unit 32 and the rotating unit 33 respectively, and the clamping unit 32 is also connected to the rotating unit 33; after the rotating unit 33 clamps the material under the action of the clamping unit 32, the lifting unit 31 can drive the rotating unit 33 to move up and down, and the rotating unit 33 can drive the material to flip.

[0050] In this embodiment, the lifting unit 31 is mainly used to drive the clamping unit 32 and the rotating unit 33 to move up and down; the rotating unit 33 is used to drive the material to flip; the clamping unit 32 acts on the rotating unit 33, and under the action of the clamping unit 32, the rotating unit 33 can clamp or loosen the material. For example, when the double-layer condenser completes the stratification, the upper condenser is pushed to the flip assembly 3, and is just located at the rotating unit 33. At this time, the clamping unit 32 works, so that the rotating unit 33 can clamp the upper condenser, and then the lifting unit 31 moves upward to provide enough space for the flipping of the condenser. At the same time, the rotating unit 33 acts to flip the condenser. After the flipping is completed, the clamping unit 32 causes the rotating unit 33 to loosen the condenser, and the condenser flows into the next process. After that, the lifting unit 31, the clamping unit 32 and the rotating unit 33 return to the initial state.

[0051] In a specific embodiment, the lifting unit 31 includes a third telescopic cylinder 311, a lifting frame 312, a guide rail 313 and a slider 314. The guide rail 313 is arranged on the fixed frame 1 along the vertical direction. The telescopic end of the third telescopic cylinder 311 is connected to the lifting frame 312, and the two sides of the lifting frame 312 cooperate with the guide rail 313 through the slider 314.

[0052] The lifting frame 312 includes a horizontal rod and vertical rods arranged on both sides of the horizontal rod. There is a certain gap between the vertical rods on both sides, and the clamping unit 32 and the rotating unit 33 are arranged in the gap. The third telescopic cylinder 311 is arranged vertically, and its telescopic end acts on the horizontal rod of the lifting frame 312, and is used to drive the entire lifting frame 312 to move up and down through the horizontal rod. In order to make the movement of the lifting frame 312 more stable, two guide rails 313 are arranged on the fixed frame 1, and each of the guide rails 313 is connected to the track on the vertical rod of the lifting frame 312 through a corresponding slider 314. In this way, when the third telescopic cylinder 311 is extended, under the action of the slider 314 and the track, the entire lifting frame 312 will move downward along the guide rail 313. Conversely, when the third telescopic cylinder 311 is retracted, under the action of the slider 314 and the track, the entire lifting frame 312 will move upward along the guide rail 313.

[0053] In a specific embodiment, the rotating unit 33 includes a first rotating plate 331, a second rotating plate 332, a clamping block 333, a rotating cylinder 334 and a sliding rod 335. One end of the first rotating plate 331 is slidably disposed on the lifting frame 312, and the other end of the first rotating plate 331 is connected to one end of the sliding rod 335 through a first linear bearing 336. One end of the second rotating plate 332 is slidably disposed on the lifting frame 312, and the other end of the second rotating plate 332 is connected to the other end of the sliding rod 335 through a second linear bearing 337. The inner sides of the first rotating plate 331 and the second rotating plate 332 are both provided with the clamping block 333, and the output end of the rotating cylinder 334 acts on the first rotating plate 331. That is, below the horizontal rod of the lifting frame 312, there are the first rotating plate 331 and the second rotating plate 332, and there is a gap between the first rotating plate 331 and the second rotating plate 332 for placing the material to be flipped. Furthermore, under the action of the clamping unit 32, the first rotating plate 331 and the second rotating plate 332 can move toward each other to clamp the material or move away from each other to loosen the material. In this embodiment, in order to realize the rotation of the first rotating plate 331 and the second rotating plate 332, a rotating cylinder 334 is provided, and the output end of the rotating cylinder 334 acts on the first rotating plate 331. In order to ensure that the second rotating plate 332 can also rotate synchronously, a sliding rod 335 is added, one end of the sliding rod 335 is connected to the first rotating plate 331 through a first linear bearing 336, and the other end of the sliding rod 335 is connected to the second rotating plate 332 through a second linear bearing 337.

[0054] In a specific embodiment, the clamping unit 32 includes a sliding cylinder 321 and a horizontal moving module 322, one end of the sliding cylinder 321 is fixed on one side inside the lifting frame 312, and the other end of the sliding cylinder 321 is connected to the second rotating plate 332, one end of the horizontal moving module 322 is fixed on the other side inside the lifting frame 312, and the other end of the horizontal moving module 322 is connected to the rotating cylinder 334 for pushing the first rotating plate 331 to move horizontally through the rotating cylinder 334.

[0055] Specifically, the horizontal moving module 322 includes a driving member, a guide rail, a slider, and a track. The track is connected to the other side of the lifting frame 312, and the guide rail is connected to the track through the slider, and the guide rail acts on the rotating cylinder 334. In this way, in the specific use process, the horizontal moving module 322 can drive the rotating cylinder 334 to move in the horizontal direction, thereby pushing the first rotating plate 331 to move horizontally, and the slide cylinder 321 can drive the second rotating plate 332 to move horizontally, so as to achieve the clamping and loosening of the rotating unit 33.

[0056] In a specific embodiment, the layered flipping mechanism further includes a control component, which is connected to the layered component 2 and the flipping component 3 respectively, and is used to control the working states of the layered component 2 and the flipping component 3. The control component includes a PLC control system.

[0057] When it is sensed that the material on the conveyor line has reached the position of the layered component 2, the PLC control system controls the first telescopic cylinder 211 to operate, and the push plate 23 descends to the edge of the upper condenser. Then the second telescopic cylinder 221 operates, and the push plate 23 pushes the upper condenser to the front along the transportation direction of the conveyor line. After that, the PLC control system controls the first telescopic cylinder 211 and the second telescopic cylinder 221 to return to their positions.

[0058] Afterwards, the PLC control system controls the third telescopic cylinder 311 to descend. At this time, the two clamping blocks 333 are just parallel to the two sides of the lower condenser. Then the slide cylinder 321 and the horizontal moving module 322 are activated, so that the first rotating plate 331 and the second rotating plate 332 hold the condenser tightly, the third telescopic cylinder 311 rises, and the rotating cylinder 334 rotates the condenser 180°. Then the third telescopic cylinder 311 descends, the slide cylinder 321 and the horizontal moving module 322 are activated to release the condenser, and the third telescopic cylinder 311 rises and returns to its original position, and the condenser flows away along the conveyor line.

[0059] In actual use, the various parts cooperate with each other and repeat over and over again to realize the function of automatic layer flipping of the double-layer condenser.

[0060] In summary, it is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous technical features can be freely combined and superimposed.

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form.
