Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic equipment decomposition, and in particular to a decomposition incinerator. Background Art

[0002] As is known, a decomposition incinerator is a high-temperature waste recycling system, which is mainly used to process waste, such as organic materials (photovoltaic equipment such as photovoltaic modules), by heating organic matter at high temperature to thermally decompose the organic matter, thereby recycling the decomposed organic matter. The photovoltaic module includes components such as glass plate, EVA film, crystalline silicon cell, EVA film, back plate, aluminum frame and junction box. When recycling the photovoltaic module, the photovoltaic module needs to be disassembled first, and the aluminum frame and junction box are partially removed; generally, an automatic frame removal machine is used to completely remove the aluminum frame, and then the junction box is manually disassembled to obtain a component that is a glass plate, EVA film, crystalline silicon cell, EVA film and back plate, and then put it into a conveying mechanism, so as to be transported into the decomposition incinerator for decomposition, so as to obtain the decomposed glass plate and crystalline silicon cell for recycling.

[0003] For example, the patent with publication number CN117509645A, publication date 2024-02-06, and titled "A Method for Recycling Silicon Materials in Solar Cells" includes the following steps: disassembling photovoltaic modules, removing the wire box and frame to obtain laminates; heating the laminates to 80-90°C, and peeling off the backboard material; heating the laminates without backboard to 80-85°C, and using a hot knife at a temperature of 90-95°C to separate the glass and the packaging film; placing the packaging film containing the cell in a pyrolysis furnace, heating it to 580-650°C under an inert atmosphere, pyrolyzing it for 40-60 minutes, decomposing the packaging film, and obtaining the cell; ultrasonically cleaning the cell to remove impurities attached to the surface and drying it; grinding the dried cell into cell powder; electrostatically sorting the cell powder to obtain silicon materials. This patent proposes a complete set of methods for recycling silicon materials from discarded photovoltaic modules, which is suitable for retired photovoltaic modules with different degrees of damage, and has the characteristics of high disassembly recovery rate, low energy consumption, low recycling cost, and environmental friendliness.

[0004] In the prior art, during the decomposition process, the glass sheet is adsorbed and fixed by a suction cup mechanism, and then separated from the crystalline silicon cell sheet by transportation by a conveying mechanism. When the suction cup mechanism adsorbs the glass sheet, due to the obvious differences when individual photovoltaic modules are scrapped, the separation time of each photovoltaic module is not exactly the same. However, the conveying mechanism in front of it continuously transports the photovoltaic modules at a uniform speed, resulting in a mismatch in the rhythm between the conveying mechanism and the separation mechanism. Summary of the invention

[0005] The object of the present invention is to provide a decomposition incinerator to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a decomposition incinerator, comprising a furnace body, in which a conveying mechanism, a separation mechanism and an incineration mechanism are sequentially arranged, and a placement rack is also arranged between the conveying mechanism and the separation mechanism, and a plurality of placement plates are arranged in the placement rack, and the plurality of placement plates are driven to perform vertical reciprocating motion to temporarily store the photovoltaic components conveyed by the conveying mechanism one by one, and at the same time, the placement plates can be driven to tilt to transport the temporarily stored photovoltaic components to the separation mechanism.

[0007] In the above-mentioned decomposition incinerator, two reciprocating motion units are relatively arranged on the top of the placement rack, and each of the reciprocating motion units preferably includes a motor. The motor is arranged on the top of the placement rack, and the motor is arranged vertically. A screw is fixed to the output shaft of the motor, and the screw is threadedly connected to the placement plate.

[0008] In the above-mentioned decomposition incinerator, the outer surface of the lead screw is threadedly connected with a threaded sleeve, and a plurality of extrusion springs are arranged between the threaded sleeve and the placement plate.

[0009] In the above-mentioned decomposition incinerator, a round hole is opened on the placement plate, the bottom end of the lead screw passes through the round hole and the threaded sleeve in sequence, and the bottom end of the lead screw is rotatably connected to the bottom of the furnace body.

[0010] In the above-mentioned decomposition incinerator, two strip grooves are provided on opposite sides of the placement frame, and the placement plate is slidably connected in the two strip grooves through two sliders, and the sliders are rotationally connected to the placement plate.

[0011] In the above-mentioned decomposition incinerator, an L-shaped plate is fixedly connected to the threaded sleeve, the L-shaped plate is slidably connected to the strip groove, and the L-shaped plate passes through the strip groove and extends to the outside of the strip groove.

[0012] In the above-mentioned decomposition incinerator, two connecting plates are arranged opposite to each other on one side of the placement rack, a through slot is opened inside each connecting plate, a movable plate is slidably connected inside the through slot, a limiting spring is arranged on one side of the movable plate, and one end of the limiting spring is arranged on the inner wall of the through slot.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5As shown, a decomposition incinerator provided by an embodiment of the present invention comprises a furnace body 1, in which a conveying mechanism, a separation mechanism and an incineration mechanism are sequentially arranged, a placement rack 2 is also arranged between the conveying mechanism and the separation mechanism, a plurality of placement plates 3 are arranged in the placement rack 2, and the plurality of placement plates 3 are driven to perform vertical reciprocating motion to temporarily store photovoltaic components conveyed by the conveying mechanism one by one, and at the same time, the placement plates 3 can be driven to tilt to convey the temporarily stored photovoltaic components to the separation mechanism.

[0027] Specifically, the overall shape of the furnace body 1 is a long strip, which is arranged horizontally and longitudinally. One end of the furnace body 1 is a feeding end, and the feeding end is mainly used to put in photovoltaic modules for transportation into the furnace body 1 for decomposition, and the other end of the furnace body 1 is a discharging end, and the discharging end is mainly used to output the separated photovoltaic modules out of the furnace body 1 for centralized recycling and reuse, and a first heating device (not shown in the figure) is arranged inside the furnace body 1 to facilitate preheating of the photovoltaic modules;

[0028] Specifically, during the decomposition process, before incineration, the aluminum frame and junction box of the photovoltaic module have been disassembled; generally, an automatic frame disassembly machine is used to completely disassemble the aluminum frame, and then the junction box is manually disassembled to obtain a component that is a glass plate, EVA film, crystalline silicon cell, EVA film and back plate (ordered from the upper surface to the lower surface). The photovoltaic module that enters the decomposition incinerator for incineration in each embodiment of the present invention is a photovoltaic module with a five-layer structure. The photovoltaic module enters the furnace body 1 for heating and decomposition. Under high temperature conditions, the EVA film and the back plate as a whole are first molten (from solid to liquid), and then gasified (liquid to gas) and discharged. That is, the two layers of EVA film and the back plate in the five layers of the photovoltaic module are all incinerated, so that the glass plate and the crystalline silicon cell are finally obtained. Two layers of components, which are then recycled and reused. In addition, an exhaust duct assembly is arranged on the top of the furnace body 1, which includes a plurality of exhaust pipes connected in parallel to the inside of the furnace body 1, and is mainly used to discharge the gas decomposed by heating in the furnace body 1, so that the gas can be reused by the external arrangement.

[0029] In this embodiment, a conveying mechanism, a separation mechanism and an incineration mechanism are sequentially arranged inside the furnace body 1, wherein the conveying mechanism comprises a first conveyor belt and a first driving unit such as a first motor, and the first motor is started to drive the first conveyor belt to convey the photovoltaic components placed on the first conveyor belt and convey them to the placement rack 2 for temporary storage;

[0030] The separation mechanism preferably includes a second conveyor belt, a suction cup, a negative pressure device and a second driving unit such as a second motor. The second motor is started to drive the second conveyor belt for conveying, and the second conveyor belt is used to receive the photovoltaic components conveyed from the placement rack 2, and then the suction cup is started to adsorb and fix the photovoltaic components conveyed on the second conveyor belt, that is, to adsorb and fix the glass plates in the photovoltaic components; since a first heating device (not shown) is arranged inside the furnace body, through continuous preheating of the first heating device, two layers of EVA film and the back plate in the five layers of the photovoltaic component are gradually changed from solid to liquid during the conveying process of the conveying mechanism, so that the glass plate is fixed by the suction cup, and the other four layers except the glass plate move with the continuous conveying of the second conveyor belt, so that the glass plate and the crystalline silicon cell sheet move relative to each other, that is, the glass plate and the crystalline silicon cell sheet are separated, that is, the separation operation is completed;

[0031] The incineration mechanism includes a second heating device (not shown) and a third conveyor belt. The two layers of EVA film and the back panel in liquid state are heated at high temperature by the second heating device, that is, the heating temperature of the second heating device is higher than the heating temperature of the first heating device. In this way, the two layers of liquid EVA film and the back panel are vaporized at high temperature, so that only the glass plate and the crystalline silicon battery cell are left. The glass plate and the crystalline silicon battery cell are conveyed out of the furnace body 1 by the third conveyor belt for recycling and reuse.

[0032] In the above description, the photovoltaic components in liquid state (molten state) are conveyed to the separation mechanism by the first conveyor belt and the second conveyor belt for separation, so that the glass plate and the crystalline silicon cell sheet are separated, and finally the two layers of EVA film and the back plate are incinerated by high temperature heating by the second heating device in the incineration mechanism, that is, the two layers of EVA film and the back plate are changed from liquid state (molten state) to vaporized state, and finally discharged from the exhaust pipe assembly. The above are all prior arts and will not be repeated.

[0033] In this embodiment, due to the obvious differences when individuals are scrapped, the separation time of each photovoltaic component is not exactly the same, but the conveying mechanism in front of it continuously conveys the photovoltaic components at a uniform speed, which leads to the mismatch between the conveying mechanism and the separation mechanism. Therefore, when the rhythm between the conveying mechanism and the separation mechanism is mismatched, it is necessary to temporarily store the photovoltaic components piled up on the first conveyor belt in the conveying mechanism, and then temporarily store the piled photovoltaic components by setting a placement rack 2. In this way, the innovation in this embodiment is that a placement rack 2 is also provided between the conveying mechanism and the separation mechanism, and a plurality of placement plates 3 are provided in the placement rack 2. The plurality of placement plates 3 are driven to reciprocate vertically to temporarily store the photovoltaic components transported by the conveying mechanism one by one, and at the same time, the placement plates 3 can be driven to tilt to transport the temporarily stored photovoltaic components to the separation mechanism.

[0034] Specifically, Figure 2 As shown, the placement rack 2 is arranged vertically, and a accommodating cavity is formed on its inner side. The purpose of its arrangement is to enable multiple placement plates 3 to slide vertically in the accommodating cavity. During the sliding stroke, the placement plates 3 can be aligned with the end of the first conveyor belt of the conveying mechanism, so that the photovoltaic components transported on the first conveyor belt can directly slide onto the aligned placement plates 3. The power here depends on the push of the first conveyor belt. The first conveyor belt can push the photovoltaic components completely away from itself, and multiple placement plates 3 can move vertically so as to be able to move to the position aligned with the end of the first conveyor belt respectively, so that multiple placement plates 3 can dock and temporarily store the photovoltaic components transported in the conveying mechanism one by one. It is noted that the sliding direction of the plurality of placement plates 3 is vertical reciprocating sliding, and the spacing between each adjacent placement plate 3 is the same, and the purpose of setting the spacing is not only to facilitate the photovoltaic components transported in the conveying mechanism to fall onto the placement plates 3 for temporary storage, but also to provide an inclined spacing for the temporarily stored photovoltaic components, so as to tilt the temporarily stored photovoltaic components, and rely on gravity to make the photovoltaic components slide and be transported to the second conveyor belt of the separation mechanism. At this time, the end of the placement plate 3 is slightly higher than the second conveyor belt, so that the end of the photovoltaic component can overlap the second conveyor belt due to sliding, and then rely on the movement of the second conveyor belt to drag the photovoltaic component and then move directly to the second conveyor belt. It should be noted that when the placement plate 3 receives the photovoltaic components on the conveying mechanism, the horizontal height of the placement plate 3 is always slightly lower than the horizontal height of the first conveyor belt. The purpose of its setting is to allow the placement plate 3 to receive the photovoltaic components transported on the conveying mechanism. Similarly, when the photovoltaic components on the placement plate 3 are tilted onto the second conveyor belt of the separation mechanism, the horizontal height of the placement plate 3 is always slightly higher than the horizontal height of the second conveyor belt of the separation mechanism. The purpose of this setting is to allow the photovoltaic components temporarily stored on the placement plate 3 to rely on gravity to slide one end onto the second conveyor belt of the separation mechanism.

[0035] When transporting photovoltaic modules, batches of photovoltaic modules are firstly fed in one by one at a uniform speed through the feeding end, and then transported by the first conveyor belt in the conveying mechanism, and preheated by the first heating device, so that the photovoltaic modules (EVA films and back sheets) being transported are changed from solid to molten or liquid, and then enter the separation mechanism. Through the operation of the separation mechanism, the glass plates and crystalline silicon cells in the photovoltaic modules are separated, and then the EVA films and back sheets in the photovoltaic modules are changed from liquid to gas through incineration by the incineration mechanism, and finally discharged from the exhaust pipe assembly, and then the processed glass plates and crystalline silicon cells are output from the discharging end for reuse;

[0036] In the present embodiment, regarding the problem of rhythm adaptation between the conveying mechanism and the separation mechanism, it should be noted that the placement plate 3 continuously receives the photovoltaic components conveyed by the first conveyor belt on the conveying mechanism, temporarily stores the photovoltaic components on the placement plate 3, and then the placement plate 3 is tilted to send the temporarily stored photovoltaic components to the second conveyor belt of the separation mechanism for transportation, and enter the separation mechanism for separation operation; wherein, the first conveyor belt of the conveying mechanism has a uniform rhythm. For example, in the process of the first conveyor belt conveying photovoltaic components, the time required is 1 second to output one photovoltaic component. Then, the time for the placement plate 3 to receive and transport the photovoltaic components to the separation mechanism must be controlled within 1 second, such as 0.5 seconds. Only in this way can the placement plate 3 have enough time to perform preparation actions, that is, to receive the photovoltaic components conveyed by the first conveyor belt on the conveying mechanism. This is a prior art and will not be elaborated.

[0037] When the rhythm between the conveying mechanism and the separation mechanism is not matched, the photovoltaic components continuously conveyed by the conveying mechanism during the separation process are temporarily stored by setting a placement rack 2. Specifically, during the temporary storage, the photovoltaic components on the conveying mechanism are taken over and temporarily stored by driving multiple placement plates 3 to perform vertical reciprocating motion. Then, the temporarily stored photovoltaic components are tilted by tilting the placement plates 3, so that they fall onto the second conveyor belt on the separation mechanism for separation operation.

[0038] The beneficial effects of this embodiment are as follows: through the placement rack 2, the photovoltaic components transported by the first conveyor belt on the conveying mechanism can be temporarily stored on the placement plate 3 inside the placement rack 2, and then the placement plate 3 is passively tilted to allow the temporarily stored photovoltaic components to fall back into the second conveyor belt on the separation mechanism for transportation, thereby avoiding the obvious differences when individual photovoltaic components are scrapped, resulting in different separation times for each photovoltaic component, causing the conveying mechanism to continuously transport photovoltaic components at a uniform speed, thereby causing the rhythm mismatch between the conveying mechanism and the separation mechanism.

[0039] In another embodiment provided by the present invention, please refer to Figure 2-Figure 5Two reciprocating motion units are relatively arranged on the top of the placement rack 2, and each of the reciprocating motion units preferably includes a third motor 4, which is arranged on the top of the placement rack 2, and the third motor 4 is arranged vertically, and a lead screw 5 is fixedly connected to the output shaft of the third motor 4, and the lead screw 5 is threadedly connected to the placement plate 3, and the specific connection method is described as follows:

[0040] The outer surface of the lead screw 5 is threadedly connected with a plurality of threaded sleeves 7, and the plurality of threaded sleeves 7 are correspondingly located below the plurality of placement plates 3, a plurality of extrusion springs 8 are arranged between the threaded sleeves 7 and the placement plates 3, a circular hole 6 is opened on the placement plates 3, the lead screw 5 sequentially passes through the plurality of circular holes 6 and the threaded sleeves 7, and the bottom end of the lead screw 5 is rotatably connected to the bottom of the furnace body 1;

[0041] Two strip grooves are formed on opposite sides of the placement rack 2, and the placement plate 3 is slidably connected to the two strip grooves through two sliders, and the sliders are rotatably connected to the placement plate 3; an L-shaped plate 12 is fixedly connected to the threaded sleeve 7, and the L-shaped plate 12 is also slidably connected to the strip groove, and the L-shaped plate 12 passes through the strip groove and extends to the outside of the strip groove;

[0042] Two connecting plates 9 are relatively arranged on the side of the placement frame 2 away from the first conveyor belt, each connecting plate 9 is provided with a through slot 10, a moving plate 13 is slidably connected to the inside of the through slot 10, a limiting spring 14 is arranged on one side of the moving plate 13, one end of the limiting spring 14 is arranged on the inner side wall of the through slot 10, the top of the moving plate 13 is fixedly connected to the limiting plate 11, the limiting plate 11 is slidably connected to the top of the connecting plate 9, and the limiting plate 11 is located on the upward movement stroke of the placement plate 3, the bottom of the moving plate 13 passes through the through slot 10, and the part of the moving plate 13 extending to the bottom of the through slot 10 is fixedly connected with a trapezoidal block 15;

[0043] Specifically, the number of the squeezing springs 8 is preferably four, and they are annularly distributed on the threaded sleeve 7, and a certain gap is set between the threaded sleeve 7 and the placement plate 3, which is not only used to arrange the squeezing spring 8 so that the squeezing spring 8 pulls the placement plate 3, that is, when the threaded sleeve 7 slides back and forth on the screw 5, the placement plate 3 is pulled by the squeezing spring 8 to achieve the reciprocating sliding of the placement plate 3 in the vertical direction. At the same time, the gap set between the threaded sleeve 7 and the placement plate 3 also provides space for the placement plate 3 to tilt, so that the photovoltaic components temporarily stored on the placement plate 3 are tilted and poured out, and fall onto the second conveyor belt of the separation mechanism under the action of gravity for transportation, so that the photovoltaic components are transported to the separation mechanism for separation operation;

[0044] It should be noted that the elastic coefficient of the extrusion spring 8 is greater than the elastic coefficient of the limit spring 14. A first inclined surface is provided on the side of the placement plate 3 and close to the second conveyor belt, and a second inclined surface matched with the first inclined surface is provided on the limit plate 11. In this way, when the threaded sleeve 7 slides downward, the placement plate 3 is also driven to slide downward synchronously. The first inclined surface on the placement plate 3 slides and abuts against the second inclined surface of the limit plate 11. At this time, the extrusion spring 8 basically does not deform or the deformation is small, while the limit spring 14 will undergo compression deformation. As the placement plate 3 continues to slide downward, the first inclined surface and the second inclined surface slide and abut and then separate. In this way, the placement plate 3 slides through the limit plate 11, that is, the limit plate 11 will not block the vertical downward movement of the placement plate 3.

[0045] In this embodiment, the positions of the two connecting plates 9 are slightly higher than the height of the second conveyor belt of the separation mechanism, so that when the placement plate 3 moves upward and abuts against the limit plate 11, that is, the placement plate 3 and the connecting plate 9 are in a flush state, the placement plate 3 is tilted behind, so that the photovoltaic components temporarily stored on the placement plate 3 are poured out and fall onto the second conveyor belt for transportation;

[0046] The end of the L-shaped plate 12 is provided with two inclined surfaces, namely the third inclined surface and the fourth inclined surface, and the third inclined surface is located above the fourth inclined surface. The trapezoidal block 15 has two inclined surfaces, namely the fifth inclined surface and the sixth inclined surface, and the fifth inclined surface is located above the sixth inclined surface.

[0047] When the placement plate 3 slides downward, the fourth inclined surface on the L-shaped plate and the fifth inclined surface on the trapezoidal block 15 are first slidably abutted, driving the movable plate 13 to slide in the through groove 10, that is, squeezing the limit spring 14. Subsequently, the first inclined surface on the placement plate 3 is slidably abutted against the second inclined surface on the limit plate 11 until the placement plate 3 passes through the limit plate 11, that is, slides to the bottom of the limit plate 11. At this time, the placement plate 3 is slightly lower than the height of the first conveyor belt, so as to receive the photovoltaic components on the first conveyor belt for temporary storage. By repeating the above operation, the photovoltaic components on the first conveyor belt are temporarily stored one by one to solve the situation when the rhythm of the conveying mechanism and the separation mechanism are not matched.

[0048] In the above description, when the placement plate 3 slides downward to temporarily store the photovoltaic components, the limiting plate 11 makes way during the downward sliding stroke of the placement plate 3, so that the placement plate 3 slides to a height lower than or slightly lower than the first conveyor belt, and the photovoltaic components on the first conveyor belt are temporarily stored one by one;

[0049] At the same time, during the process of the limit plate 11 giving way, the placement plate 3 is allowed to slide through the limit plate 11 through the sliding abutment between the first inclined surface and the second inclined surface, and the sliding abutment between the fourth inclined surface and the fifth inclined surface to temporarily store the photovoltaic components; and in this process, the placement plate 3 always slides downward in a horizontal state to temporarily store the photovoltaic components.

[0050] When the placing plate 3 slides upward, the temporarily stored photovoltaic components are tilted and poured out to fall into the second conveyor belt of the separation mechanism for transportation, thereby performing a separation operation, wherein, when the placing plate 3 slides upward to abut against the bottom of the limiting plate 11, the continuous operation of the third motor 4 drives the placing plate 3 to continue to slide upward, and since the limiting plate 11 is in the upward sliding stroke of the placing plate 3, the placing plate 3 is forced to tilt during the upward sliding, thereby pouring out the temporarily stored photovoltaic components, and then, the third inclined surface on the L-shaped plate 12 gradually abuts against and abuts against the sixth inclined surface until the sixth inclined surface is slid and abutted, that is, the moving plate 13 and the limiting plate 11 are pushed as a whole to slide away from the placing plate 3, so that the placing plate 3 passes through the limiting plate 11, and under the rebound of the extrusion spring 8, the placing plate 3 is restored to a horizontal state and slides upward, and then the photovoltaic components on the next placing plate 3 are tilted out, thereby entering the separation mechanism for a separation operation;

[0051] When the load plate 3 is lowered, the load plate 3 is lowered to the support frame 11, and the load plate 3 is lowered to the support frame 11, so that the load plate 3 is lowered to the support frame 11, and the load plate 3 is lowered to the support frame 11.

[0052] In this embodiment, the placement plate 3 has two states:

[0053] When the placement plate 3 is in the first state, the placement plate 3 is in a horizontal state, and the placement plate 3 is slightly lower than the height of the first conveyor belt. At this time, the placement plate 3 is used to temporarily store the photovoltaic components on the first conveyor belt;

[0054] When the placement plate 3 is in the second state, the placement plate 3 is in an inclined state, and the placement plate 3 is slightly higher than the height of the second conveyor belt. At this time, the placement plate 3 is used to tilt the temporarily stored photovoltaic components and pour them onto the second conveyor belt for transportation;

[0055] Specifically, when switching from the first state to the second state, the third motor 4 is started so that the output shaft of the third motor 4 drives the lead screw 5 to rotate, so that the threaded sleeve 7 on the lead screw 5 and the placement plate 3 (horizontal state) slide upward synchronously, and the placement plate 3 abuts against the limit plate 11, so that the placement plate 3 cannot slide upward and is forced to tilt (rotate) while sliding upward, so as to dump the temporarily stored photovoltaic components;

[0056] The switching action from the first state to the second state is assisted by the limit plate 11. Specifically, when the rhythm between the conveying mechanism and the separation mechanism is not matched, the photovoltaic components on the conveying mechanism need to be temporarily stored first. By starting the third motor 4, the lead screw 5 on the output shaft of the third motor 4 is rotated to drive the threaded sleeve 7 and the placement plate 3 to slide downward synchronously, so that the fourth inclined surface on the L-shaped plate and the fifth inclined surface on the trapezoidal block 15 are first slidably abutted, driving the moving plate 13 to slide in the through groove 10, that is, squeezing the limit spring 14. At the same time, the first inclined surface on the placement plate 3 is slidably abutted against the second inclined surface on the limit plate 11 until the placement plate 3 passes through the limit plate 11, that is, slides to the bottom of the limit plate 11. At this time, the placement plate 3 is slightly lower than the height of the first conveyor belt, thereby receiving the photovoltaic components on the first conveyor belt for temporary storage.

[0057] When the temporarily stored photovoltaic components are tilted and poured out, the third motor 4 is started again to make the placement plate 3 slide upward to abut against the bottom of the limit plate 11. The third motor 4 is continuously operated to drive the placement plate 3 to continue to slide upward, so as to force the placement plate 3 to tilt while sliding upward, thereby pouring out the temporarily stored photovoltaic components.

[0058] Then the third inclined surface on the L-shaped plate 12 gradually comes into contact with and abuts the sixth inclined surface until it slides and abuts the sixth inclined surface, that is, it pushes the movable plate 13 and the limiting plate 11 to slide away from the placement plate 3 as a whole, so that the placement plate 3 passes through the limiting plate 11, and under the rebound of the extrusion spring 8, the placement plate 3 is restored to a horizontal state and slides upward, thus preparing for the horizontal downward sliding process of the above-mentioned placement plate 3, thereby entering the next temporary storage operation.

[0059] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
