Description

Technical Field

[0001] This application relates to the field of photovoltaic cell technology, and in particular to an unpacking mechanism and equipment. Background Technology

[0002] Solar cells are the basic unit for generating electricity in solar photovoltaic modules. When sunlight shines on a solar cell, the semiconductor material inside the cell absorbs photon energy, generates electron-hole pairs, and thus forms an electric current, achieving photoelectric conversion.

[0003] To protect solar cells from damage during transportation and handling, they are typically packaged in boxes. Before entering the production line, the cell stacks (i.e., multiple stacked cells) need to be removed from the boxes. Currently, the cells are usually removed manually, which cannot meet the efficiency requirements of current cell processing equipment (such as stringers). Utility Model Content

[0004] The first objective of this application is to provide an unpacking mechanism to solve the technical problem of low efficiency in unpacking and material handling using existing manual unpacking methods.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A packaging unpacking mechanism includes a frame, a first drive assembly, a first platform rotatably mounted on the frame about a first rotation axis, and a limiting structure mounted on the first platform. The first drive assembly is configured to drive the first platform to rotate relative to the frame. The first platform has a first support surface for carrying a package. The first support surface is switchable between a horizontal state and a non-horizontal state at an angle to the horizontal plane during rotation of the first platform. The limiting structure is configured to restrict the position of the package on the first support surface during rotation of the first platform.

[0007] During the transition from a horizontal to a non-horizontal state, the first support surface can rotate the packaging box so that the opening of the packaging box faces downward, thereby allowing the sheet assembly inside the packaging box to slide out from the packaging box under the action of gravity.

[0008] A wafer assembly consists of at least two wafers stacked sequentially, and the wafers are either solar cells, silicon wafers, or wafers used in the fabrication process.

[0009] The unpacking mechanism operates as follows: Initially, the first support surface is horizontal. First, a packaging box with one side open is placed on the first support surface; alternatively, the box can be placed on the first support surface before the seal is opened. Next, the first platform is rotated relative to the frame. During this process, the first platform rotates the packaging box on it synchronously, causing the opening of the box to tilt downwards or vertically downwards. At this point, the sheet assembly inside the packaging box slides out from the opening under gravity, thus achieving unpacking and material retrieval. This unpacking mechanism reduces labor costs and improves unpacking and loading efficiency by tilting or vertically positioning the packaging box and utilizing the weight of the sheet assembly itself.

[0010] In some embodiments, the limiting structure includes a plurality of stops, which together form an area for limiting the packaging box;

[0011] And / or, the limiting structure includes a negative pressure chamber or a suction cup, which is located below the first support surface. At least one through hole is provided on the first support surface, and the negative pressure chamber or suction cup adsorbs and limits the packaging box on the first support surface through the through hole.

[0012] The limiting structure may include any one of a stop block, a negative pressure chamber, and a suction cup, or it may include both a stop block and a negative pressure chamber, or both a stop block and a suction cup. When the limiting structure includes multiple stops, the limiting area formed by the multiple stops restricts the four sides of the packaging box and does not exert pressure on the stacked sheet assembly inside the box. Therefore, this limiting area will not affect the sheet assembly from sliding out of the packaging box. When the limiting structure includes a negative pressure chamber, multiple through holes communicating with the negative pressure chamber are provided on the first support surface. When the packaging box is placed on the first support surface, the negative pressure chamber adsorbs and limits the packaging box on the first support surface through the through holes. When the limiting structure includes a suction cup, the suction end of the suction cup is connected to the through holes on the first support surface, and the suction cup adsorbs and limits the packaging box on the first support surface through the through holes.

[0013] In some embodiments, the unpacking mechanism further includes a forked finger assembly slidably disposed on a first platform and a second driving assembly, the second driving assembly being configured to drive the forked finger assembly to slide relative to the first platform.

[0014] The interdigitated assembly includes a first interdigitated finger and a second interdigitated finger that are positioned opposite each other and spaced apart. The first interdigitated finger and the second interdigitated finger can extend into the interior of the packaging box, and the gap between the first interdigitated finger and the second interdigitated finger is greater than the thickness of the sheet assembly inside the packaging box.

[0015] When a packaging box containing the sheet assembly is supported on the first support surface, the forked finger assembly can slide relative to the first platform in a direction close to the opening of the packaging box, so that both forked fingers are inserted into the packaging box and located on the upper and lower sides of the sheet assembly respectively. At this time, the first and second forked fingers can block the packaging box, so that the packaging box is restricted on the first support surface during the process of the sheet assembly sliding out of the packaging box. In addition, in order to protect the sheet assembly, a protective layer is generally laid on the upper and lower surfaces of the sheet assembly inside the packaging box. The protective layer includes at least one of corrugated paper, sponge pad, pearl cotton, and tracing paper. When a protective layer is present inside the packaging box, the first and second forked fingers can also block the protective layer, so that the protective layer is trapped inside the packaging box during the process of the sheet assembly sliding out of the packaging box, which facilitates the recycling of the protective layer. At the same time, the protective layer does not need to be removed during subsequent processing of the sheet assembly, simplifying the processing steps of the sheet assembly.

[0016] In some embodiments, the interval between the first interdigitate and the second interdigitate is configured to be adjustable;

[0017] And / or, the interdigital assembly further includes an interdigital drive source disposed on the first platform, wherein the power output end of the interdigital drive source is connected to at least one of the first interdigital finger and the second interdigital finger to adjust the spacing between the first interdigital finger and the second interdigital finger.

[0018] And / or, in the first platform and the interdigitated assembly, one of them is provided with a first guide rail, and the other is provided with a first slider, the first slider being slidably disposed on the first guide rail.

[0019] By setting the interval between the first and second forked fingers to be adjustable, the structure can accommodate sheet assemblies of different thicknesses, thus broadening its applicability. The interval between the first and second forked fingers can be adjusted manually or automatically. When the interval is adjusted automatically, the forked finger assembly also includes a forked finger drive source mounted on the first platform, which adjusts the distance between the first and second forked fingers. In embodiments where the forked finger assembly also includes a forked finger drive source, after both forked fingers are inserted into the packaging box and positioned on the upper and lower sides of the sheet assembly respectively, the forked finger drive source can be configured to drive the first and second forked fingers to move away from each other, thereby opening the packaging box and facilitating the sliding of the sheet assembly out of the packaging box. Furthermore, to limit the movement trajectory of the forked finger assembly relative to the first platform, a guide rail slider assembly can be provided between the first platform and the forked finger assembly.

[0020] In some embodiments, the first platform includes a support plate rotatably mounted on a frame about a first rotation axis and a base plate slidably mounted on the support plate, wherein the surface of the base plate away from the support plate is a first support surface.

[0021] When the control base plate slides relative to the support plate, the base plate will cause the packaging box on it to slide synchronously relative to the support plate, thereby adjusting the position of the packaging box relative to the support plate.

[0022] In some embodiments, the unpacking mechanism further includes a third drive component configured to drive the base plate to slide relative to the support plate.

[0023] And / or, between the support plate and the base plate, one of which is provided with a first guide rail and the other is provided with a first slider, the first slider being slidably mounted on the first guide rail.

[0024] The sliding of the base plate relative to the support plate is controlled by a third drive component, which increases the automation level of the unpacking mechanism and reduces the amount of manual labor required. To limit the movement trajectory of the base plate relative to the support plate, a guide rail slider assembly can be installed between the base plate and the support plate.

[0025] In some embodiments, the unpacking mechanism further includes a fourth drive assembly and a second platform rotatably mounted on the frame. The fourth drive assembly is configured to drive the second platform to rotate relative to the frame, and the rotation center line of the second platform relative to the frame is parallel to or coincides with the rotation center line of the first platform relative to the frame.

[0026] The second stage has a second support surface and a support surface that are perpendicular to each other. Both the second support surface and the support surface can switch between a horizontal state and a non-horizontal state that is at an angle to the horizontal plane during the rotation of the second stage. The second support surface is configured to be parallel to the first support surface so that the sheet assembly on the first support surface can slide onto the second support surface. The support surface is configured to support the lower side of the sheet assembly.

[0027] During the unpacking process, the above-mentioned unpacking mechanism first controls the first platform to rotate relative to the frame and drives the packaging box to rotate, so that the first support surface forms an angle α with respect to the horizontal plane and the opening of the packaging box faces downward; before or at the same time as the first platform rotates, the second platform is controlled to rotate relative to the frame, so that the second support surface forms an angle α with respect to the horizontal plane; when both the first and second support surfaces form an angle α with respect to the horizontal plane, the sheet assembly inside the packaging box 100 slides out from the opening to the second support surface under the action of gravity. During this process, when the sheet assembly comes into contact with the supporting surface, the supporting surface can provide support for the sheet assembly and prevent the sheet assembly from sliding off the second support surface.

[0028] In some embodiments, the second platform includes a flap rotatably mounted on the frame, the end of the flap away from the first platform having a support portion perpendicular to the flap, and the surface of the support portion facing the first platform being a supporting surface;

[0029] Alternatively, the second platform includes a flap rotatably mounted on the frame, a support block slidably mounted on the flap, and a fifth drive assembly drivenly connected to the support block. The surface of the support block facing the first platform is the support surface. The fifth drive assembly is configured to drive the support block to slide toward or away from the first platform so that the support block supports the sheet assembly on the side away from the packaging box during the slide-out process.

[0030] In embodiments where the flap has a support portion, the relative positions of the supporting surface and the second support surface remain unchanged. In embodiments where a support block is provided on the flap, the supporting surface slides away from the first platform on the second support surface during the slide-out of the sheet assembly. This provides support for the sheet assembly during its descent, preventing it from deviating from the sliding path, and also controls the descent speed of the sheet assembly, allowing it to smoothly detach from the packaging box.

[0031] In some embodiments, when the second platform includes a flip plate and a support block, a third guide rail is provided on one of the flip plate and the support block, and a third slider is provided on the other, with the third slider slidably disposed on the third guide rail.

[0032] And / or, a cushioning pad is provided on the supporting surface.

[0033] By incorporating a guide rail slider assembly between the flap and the support block, the movement trajectory of the support block relative to the flap can be limited. A buffer pad on the support surface provides cushioning when the sheet assembly comes into contact with the support surface, preventing wear or breakage of the sheet assembly.

[0034] In some embodiments, one, two or more rolling elements are provided on the second platform; each rolling element is located at one end of the flip plate near the first platform, and the contact plates of each rolling element are arranged collinearly on one side.

[0035] The rolling element can be a ball or a roller. The rolling element can prevent friction between the sheet assembly and the second support surface, which helps the sheet assembly fall from the packaging box by gravity and slide onto the second support surface. At the same time, it can prevent wear on the side of the sheet assembly that is close to the second support surface during the downward movement.

[0036] In some embodiments, the second stage further includes a mounting plate rotatably disposed on the frame and a sixth drive assembly disposed on the mounting plate;

[0037] The flap is rotatably mounted on the mounting plate. The rotation center line of the flap relative to the mounting plate and the rotation center line of the mounting plate relative to the frame are parallel and located on both sides of the flap. The sixth drive assembly is connected to the flap drive to drive the flap to rotate relative to the mounting plate.

[0038] The above arrangement is to push the wafer assembly further out relative to the rack to facilitate subsequent processing of the wafer assembly.

[0039] In some embodiments, the unpacking mechanism further includes a pushing component, which includes a pushing element and a pushing element driving source;

[0040] The pusher is slidably disposed on the second platform in a direction perpendicular to the second support surface. The pusher drive source is configured to drive the pusher to slide so as to change the protrusion length of the pusher relative to the second support surface.

[0041] One operating mode of the pushing assembly is as follows: during the sliding of the sheet assembly from the first support surface to the second support surface, the pushing component is controlled to protrude relative to the second support surface, allowing the sheet assembly to move smoothly to the second support surface; after the sheet assembly is completely moved to the second support surface, the pushing component is controlled to retract to the side of the second support surface away from the sheet assembly, so that the sheet assembly is in close contact with the second support surface. Another operating mode of the pushing assembly is as follows: after the sheet assembly is completely moved to the second support surface, the pushing component is controlled to move relative to the second platform to increase or decrease the protrusion length of the pushing component relative to the second support surface. In this case, the sheet assembly, pushed by the pushing component, may move, rotate, or swing relative to the second support surface. During the operation of the unpacking mechanism, the operating mode of the pushing assembly can be selected according to the processing requirements of the sheet assembly.

[0042] The second objective of this application is to provide a packaging unpacking device, which includes two packaging unpacking mechanisms as described above, the two packaging unpacking mechanisms being arranged opposite each other with the vertical plane as the center of symmetry, and the two packaging unpacking mechanisms being able to approach or move away from each other in the horizontal direction.

[0043] When the two second platforms are rotated to the point where both second support surfaces are in an upright position, a gap can be formed between the pushing components of the two unpacking mechanisms for placing sheet groups in a non-horizontal state, and the pushing components of the two unpacking mechanisms are configured to alternately push the sheet groups in the gap so that the sheet groups swing left and right relative to the upright surface.

[0044] After removing the sheet assembly from the packaging box, this unpacking equipment uses two cooperating unpacking mechanisms to swing the assembly, causing misalignment between adjacent sheets and dispersing them. After swinging, the relatively dispersed arrangement of the sheets results in minimal friction, preventing excessive pressure on the sheets during subsequent centering and straightening, thus avoiding breakage or fragmentation and improving the sheet sorting effect. Furthermore, while one unpacking mechanism is handling the sheet sorting step, the other can handle the loading step, further enhancing the efficiency of unpacking and sheet handling.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through an intermediate medium; they can refer to a mechanical connection or an electrical connection.

[0068] Example 1

[0069] The manufacturing process of solar cells mainly includes the following steps: (1) silicon wafer preparation: silicon ore is prepared into silicon wafers through refining, cutting and other technologies; (2) surface texturing: a tiny pyramid structure is formed on the surface of the silicon wafer; (3) diffusion junction formation: a PN junction is formed on the silicon wafer; (4) peripheral etching: the N-type silicon at the edge of the silicon wafer is removed to isolate the positive and negative electrodes of the battery; (5) electrode fabrication: electrodes are fabricated on the front and back sides of the solar cell; (6) anti-reflection film preparation: an anti-reflection film is deposited on the front side of the solar cell to form the final solar cell. Among them, the silicon wafers or solar cells in steps (2) to (5) are preparation stage wafers. The wafer group 200 described in this application consists of at least two wafers stacked sequentially, and the wafers are solar cells, silicon wafers or preparation stage wafers; that is, the wafer group 200 is formed by stacking multiple thin sheets sequentially along the thickness direction of each thin sheet. The tablet assembly 200 is usually placed inside the packaging box 100 for transfer. Before the tablet assembly 200 enters the production line, it needs to be taken out of the packaging box 100.

[0070] This application provides an unpacking mechanism for removing the sheet assembly 200 from the packaging box 100, see reference. Figure 1 , Figure 3 , Figure 12 as well as Figure 13The unpacking mechanism includes a frame 1, a first drive assembly 5, a first platform 2 rotatably mounted on the frame 1 about a first rotation axis, and a limiting structure mounted on the first platform 2. The first drive assembly 5 is configured to drive the first platform 2 to rotate relative to the frame 1. The first platform 2 has a first support surface for supporting the packaging box 100. The first support surface can switch between a horizontal state and a non-horizontal state at an angle to the horizontal plane during the rotation of the first platform 2. The limiting structure is configured to limit the position of the packaging box 100 on the first support surface during the rotation of the first platform 2.

[0071] During the transition from a horizontal to a non-horizontal state, the first support surface can rotate the packaging box 100 so that the opening of the packaging box 100 faces downward, thereby causing the sheet assembly 200 inside the packaging box 100 to slide out from the packaging box 100 under the action of gravity.

[0072] The working process of the above-mentioned unpacking mechanism is as follows: Figure 1 and Figure 12 As shown, in the initial state, the first support surface is horizontal; first, place the packaging box 100 with one side open on the first support surface, or the packaging box 100 can be unsealed after it has been placed on the first support surface; then, as... Figure 3 and Figure 13 As shown, the first platform 2 is controlled to rotate relative to the frame 1. During this process, the first platform 2 drives the packaging box 100 on it to rotate synchronously and makes the opening of the packaging box 100 tilt downward or vertically downward, so that the sheet group 200 inside the packaging box 100 slides out from the opening of the packaging box 100 under the action of gravity, thereby realizing unpacking and material handling.

[0073] It should be noted that when the first support surface is not horizontal, it can be in an inclined state relative to the horizontal plane or in an upright state perpendicular to the horizontal plane. When the first support surface is not horizontal, the angle α between the first support surface and the horizontal plane can be between 45° and 90°, adjusted according to the processing requirements of the sheet assembly 200. It can be understood that the larger the angle α between the first support surface and the horizontal plane, the easier it is for the sheet assembly 200 to slide out of the packaging box 100, and the faster the sheet assembly 200 slides out.

[0074] As described above, the unpacking mechanism provided in this application achieves unpacking and material retrieval by tilting or standing the packaging box 100 upright and utilizing the weight of the sheet assembly 200 itself, thereby reducing the labor cost of unpacking and material retrieval and improving the efficiency of unpacking and material loading.

[0075] There are many different types of packaging boxes; some are like... Figure 1The side-opening box type shown is characterized by the opening of the packaging box 100 being located on the side; some are top and bottom cover types, characterized by the top and bottom covers being snap-fitted together, and the side of the bottom cover of this type of packaging box 100 can also form an opening after the top and bottom covers are opened. Regardless of the type of packaging box 100, its opening method can be divided into flip-top type, detachable type, etc.; for the side-opening box type packaging box 100, the flip-top type is characterized by a sealing cap used to close the opening being rotatably connected to the main body of the packaging box (e.g., Figure 1 As shown), the detachable type is characterized by the lid being removable from the main body of the packaging box; for the top and bottom lid type packaging box 100, the flip-top type is characterized by the top and bottom lids being rotatably connected to each other, while the detachable type is characterized by the top and bottom lids being detachable; all of the above types of packaging boxes can be unpacked and the materials removed using the unpacking mechanism provided in this application. After the packaging box 100 is opened, an opening is formed on the side of the packaging box 100 perpendicular to the stacking direction of the sheet assembly 200, so that the sheet assembly 200 inside the box can be poured out relatively neatly from this opening.

[0076] As an optional embodiment, the limiting structure includes a plurality of stops 21, which together form an area for limiting the packaging box 100;

[0077] And / or, the limiting structure includes a negative pressure chamber or a suction cup, which is located below the first support surface. At least one through hole is provided on the first support surface, and the negative pressure chamber or suction cup adsorbs and limits the packaging box 100 on the first support surface through the through hole.

[0078] The limiting structure may include any one of the following: a stop 21, a negative pressure chamber, and a suction cup; it may also include both a stop 21 and a negative pressure chamber, or both a stop 21 and a suction cup. When the limiting structure includes multiple stops 21, such as... Figure 8 and Figure 9 As shown, the limiting area enclosed by multiple stops 21 is used to restrict the four sides of the packaging box 100, and will not exert pressure on the stacked sheet assembly 200 inside the box. Therefore, this limiting area will not affect the sheet assembly 200 from sliding out of the packaging box 100. When the limiting structure includes a negative pressure chamber, refer to... Figure 8 In one embodiment, the first platform 2 includes a base plate 23, which is configured with an internal hollow structure to form a negative pressure cavity inside. A first support surface is provided on the base plate 23, and multiple through holes communicating with the negative pressure cavity are formed on the first support surface. Thus, when the packaging box 100 is placed on the first support surface, the negative pressure cavity adsorbs and confines the packaging box 100 on the first support surface through the through holes. When the confining structure includes a suction cup, the suction end of the suction cup is connected to the through holes on the first support surface, thus the suction cup adsorbs and confines the packaging box 100 on the first support surface through the through holes.

[0079] As an optional embodiment, the first drive assembly 5 includes a first drive source, which can be a piston cylinder (specifically, any one of an electric cylinder, pneumatic cylinder, or hydraulic cylinder) or a motor; the power output end of the first drive source can be directly connected to the first platform 2, or indirectly connected to the first platform 2 through a rotary transmission structure such as a pulley belt, sprocket chain, etc. For example, referring to... Figure 12 and Figure 13 The first driving source is a cylinder, and the two ends of the first driving source are respectively hinged to the frame 1 and the first platform 2. Thus, the two ends of the first driving source drive the first platform 2 to rotate relative to the frame 1 during the extension and retraction process.

[0080] Continue to refer to Figure 8 and Figure 9 In some embodiments, the unpacking mechanism further includes a forked finger assembly 4 slidably disposed on the first platform 2 and a second drive assembly, the second drive assembly being configured to drive the forked finger assembly 4 to slide relative to the first platform 2.

[0081] The interdigitated component 4 includes a first interdigitated finger 41 and a second interdigitated finger 42 that are opposite to each other and spaced apart. The first interdigitated finger 41 and the second interdigitated finger 42 can extend into the interior of the packaging box 100, and the gap between the first interdigitated finger 41 and the second interdigitated finger 42 can be greater than the thickness of the sheet assembly 200 inside the packaging box 100.

[0082] Optionally, the number of interdigital components 4 is one set or two sets. When the number of interdigital components 4 is two sets, the two sets of interdigital components 4 are located on both sides of the opening of the packaging box 100; the two sets of interdigital components 4 can be driven by the same second drive component or by different drive components.

[0083] Reference Figure 8When the packaging box 100 containing the sheet assembly 200 is supported on the first support surface, the forked finger assembly 4 is configured to slide relative to the first platform 2 in a direction close to the opening of the packaging box 100, so that both forked fingers are inserted into the packaging box 100 and located on the upper and lower sides of the sheet assembly 200 respectively. At this time, the first forked finger 41 and the second forked finger 42 can block the packaging box 100, so that the packaging box 100 is restricted on the first support surface during the process of the sheet assembly 200 sliding out of the packaging box 100. In addition, to protect the sheet assembly 200, a protective layer is generally laid on both the upper and lower surfaces of the sheet assembly 200 inside the packaging box 100. The protective layer includes at least one of corrugated paper, sponge pad, pearl cotton, and tracing paper. When the protective layer is inside the packaging box 100, the first forked finger 41 and the second forked finger 42 can also block the protective layer, so that the protective layer is trapped inside the packaging box 100 when the sheet assembly 200 slides out of the packaging box 100, which facilitates the recycling of the protective layer. At the same time, the protective layer does not need to be removed during the subsequent processing of the sheet assembly 200, simplifying the processing steps of the sheet assembly 200.

[0084] When the first support surface carries an unloaded packaging box 100 (i.e., the sheet assembly 200 is removed from the packaging box 100), the fork assembly 4 is also configured to slide relative to the first platform 2 in a direction away from the opening of the packaging box 100, so that the two forks can be removed from the packaging box 100 so that the packaging box 100 can be removed from the first platform 2.

[0085] As an optional embodiment, the second drive assembly includes a second drive source, which can be a piston cylinder (specifically, any one of an electric cylinder, pneumatic cylinder, or hydraulic cylinder) or a motor. The power output end of the second drive source can be directly connected to the forked finger assembly 4, or indirectly connected to the forked finger assembly 4 through linear transmission structures such as a lead screw nut, pulley belt, or sprocket chain. Since pneumatic cylinders have advantages such as low cost, easy installation, small footprint, and rapid response, the second drive source is generally a pneumatic cylinder, with its two ends connected to the first platform 2 and the forked finger assembly 4, respectively. Alternatively, the second drive assembly can also be an electric lead screw slide, which has advantages such as compact structure and accompanying guiding function, and is widely used in linear drive applications.

[0086] In some embodiments, in the first platform 2 and the interdigital assembly 4, one is provided with a first guide rail 71, and the other is provided with a first slider, the first slider being slidably disposed on the first guide rail 71. Figure 8 As shown, a first guide rail 71 is provided on the first platform 2, and a first slider is provided on the interdigital component 4. The guide rail and slider assembly can limit the movement trajectory of the interdigital component 4 relative to the first platform 2.

[0087] In some embodiments, the interval between the first interdigital finger 41 and the second interdigital finger 42 is configured to be adjustable, and the adjustment method can be manual or automatic.

[0088] When the interval between the first forked finger 41 and the second forked finger 42 is adjusted manually, in one embodiment, the forked finger assembly 4 further includes a forked finger mounting seat slidably disposed on the first platform 2. Each forked finger is provided with an adjustment elongated hole, through which fasteners such as screws can pass and be screwed onto the forked finger mounting seat, thereby mounting each forked finger on the forked finger mounting seat. When it is necessary to adjust the interval between the first forked finger 41 and the second forked finger 42, the fastener on at least one forked finger is loosened, and the forked finger is moved along the length direction of the adjustment elongated hole, thereby adjusting the interval between the first forked finger 41 and the second forked finger 42. In another embodiment, the forked finger assembly 4 is an accessory with various specifications, and the interval between the first forked finger 41 and the second forked finger 42 is different in each forked finger assembly 4.

[0089] When the interval between the first forked finger 41 and the second forked finger 42 is automatically adjusted, the forked finger assembly 4 further includes a forked finger drive source disposed on the first platform 2. The power output end of the forked finger drive source is connected to at least one of the first forked finger 41 and the second forked finger 42 to adjust the interval between the first forked finger 41 and the second forked finger 42. For example, the forked finger drive source is a cylinder (which can be a one-way cylinder or a thumb cylinder). The cylinder body of the forked finger drive source is slidably disposed on the first platform 2, and the power output end of the forked finger drive source is connected to at least one forked finger. When the forked finger drive source is working, it drives the first forked finger 41 and the second forked finger 42 to approach or move away from each other.

[0090] By setting the interval between the first fork 41 and the second fork 42 to be adjustable, it can adapt to sheet assembly 200 of different thicknesses, thus broadening its applicability. When the interval between the first fork 41 and the second fork 42 is adjusted manually, the interval is generally adjusted according to the thickness of the sheet assembly 200 before the unpacking mechanism is officially running, or different accessories are replaced. When the interval between the first fork 41 and the second fork 42 is adjusted automatically, the interval can be adjusted before the unpacking mechanism is officially running, or it can be adjusted during operation. In some operating modes of the fork assembly 4, after both forks are inserted into the packaging box 100 and are located on the upper and lower sides of the sheet assembly 200 respectively, the fork drive source is also configured to drive the first fork 41 and the second fork 42 to move away from each other, so as to open the opening of the packaging box 100, making it easier for the sheet assembly 200 to slide out of the packaging box 100.

[0091] Continue to refer to Figure 8The first platform 2 includes a support plate 22 rotatably mounted on the frame 1 around a first rotation axis and a base plate 23 slidably mounted on the support plate 22. The surface of the base plate 23 away from the support plate 22 is a first support surface; a limit structure is provided on the base plate 23. When the base plate 23 is controlled to slide relative to the support plate 22, the base plate 23 will drive the sheet assembly 200 on the base plate 23 to slide synchronously relative to the support plate 22, thereby adjusting the position of the packaging box 100 relative to the support plate 22. Furthermore, the unpacking mechanism also includes a third drive assembly, which is configured to drive the base plate 23 to slide relative to the support plate 22; the structure of the third drive assembly is similar to that of the second drive assembly and will not be described in detail here.

[0092] Based on the above structure, the forked finger assembly 4 is slidably disposed on the support plate 22 of the first platform 2. The forked finger assembly 4 and the base plate 23 can slide synchronously or relative to the support plate 22. For example, during the insertion or removal of the first forked finger 41 and the second forked finger 42 into the packaging box 100, the base plate 23 is kept stationary relative to the support plate 22, and the forked finger assembly 4 is slid relative to the support plate 22 in a direction close to or away from the base plate 23. After the first forked finger 41 and the second forked finger 42 are inserted into the packaging box 100, the forked finger assembly 4 and the base plate 23 are slid synchronously relative to the support plate 22 to change the position of the packaging box 100 relative to the support plate 22.

[0093] In some embodiments, between the support plate 22 and the base plate 23, one is provided with a first guide rail 71, and the other is provided with a first slider, the first slider being slidably disposed on the first guide rail 71. Figure 8 As shown, a first guide rail 71 is provided on the support plate 22, and a first slider is provided on the base plate 23. The guide rail and slider assembly can limit the movement trajectory of the base plate 23 relative to the support plate 22. In this embodiment, the support plate 22 and the interdigital assembly 4 share a guide rail; of course, in other embodiments, they can be connected to different guide rails respectively.

[0094] Continue to refer to Figure 1 , Figure 12 as well as Figure 13 The unpacking mechanism also includes a fourth drive assembly 8 and a second platform 3 rotatably mounted on the frame 1. The fourth drive assembly 8 is configured to drive the second platform 3 to rotate relative to the frame 1. The rotation center line of the second platform 3 relative to the frame 1 is parallel to or coincides with the rotation center line of the first platform 2 relative to the frame 1.

[0095] The second platform 3 has a second support surface and a support surface that are perpendicular to each other. Both the second support surface and the support surface can switch between a horizontal state and a non-horizontal state that is at an angle to the horizontal plane during the rotation of the second platform 3. The second support surface is configured to be parallel to the first support surface so that the sheet assembly 200 on the first support surface can slide onto the second support surface. The support surface is configured to support the lower side of the sheet assembly 200.

[0096] During the material handling process, the aforementioned unpacking mechanism first refers to: Figure 3 and Figure 13 The first platform 2 is controlled to rotate relative to the frame 1 and drive the packaging box 100 to rotate, so that the first support surface forms an angle α with respect to the horizontal plane and the opening of the packaging box 100 faces downward.

[0097] Before or while the first platform 2 is rotating, the second platform 3 is controlled to rotate around the second horizontal center line, so that the second support surface forms an angle α with respect to the horizontal plane.

[0098] When both the first and second support surfaces are at an angle α relative to the horizontal plane (i.e., when they are parallel to each other), the sheet assembly 200 inside the packaging box 100 slides out from the opening to the second support surface under the action of gravity. During this process, when the sheet assembly 200 comes into contact with the supporting surface, the supporting surface can provide support for the sheet assembly 200 and prevent the sheet assembly 200 from sliding off the second support surface.

[0099] In some embodiments, a cushioning pad is provided on the support surface, which can provide cushioning when the sheet assembly 200 comes into contact with the support surface, thereby preventing the sheet assembly 200 from wearing or breaking.

[0100] In some embodiments, refer to Figure 2 and Figure 3 The second platform 3 includes a second flap 32 rotatably mounted on the frame, a support block 34 slidably mounted on the flap 32, and a fifth drive assembly pulsatorically connected to the support block 34. The surface of the support block 34 facing the first platform 2 is the supporting surface. The fifth drive assembly is configured to drive the support block 34 to slide toward or away from the first platform 2, so that the support block 34 supports the side of the sheet assembly 200 away from the packaging box 100 during the sliding process of the sheet assembly 200. In the above structure, the structure of the fifth drive assembly is similar to that of the second drive assembly, and will not be described again here.

[0101] During the material handling process, the support block 34 rests on the lower side of the sheet assembly 200. It provides support for the sheet assembly 200 as it slides down, preventing it from deviating from the sliding path. It also controls the sliding speed of the sheet assembly 200, allowing it to slide smoothly out of the packaging box 100. In some embodiments, while rotating the restrained packaging box 100, the support block 34 is controlled to retract along the sliding path of the sheet assembly 200. Supported by the support block 34, the sheet assembly 200 gradually slides out of the packaging box 100 under the influence of gravity. In other embodiments, when the restricted packaging box 100 is rotated, the control block 34 remains stationary relative to the packaging box 100 and blocks the opening of the packaging box 100. At this time, the sheet assembly 200 will not slide out of the packaging box 100 due to the block 34. After the restricted packaging box 100 is rotated until its opening is tilted downwards or vertically downwards relative to the horizontal plane, the rotation of the restricted packaging box 100 is stopped and the control block 34 is moved backwards along the sliding path of the sheet assembly 200. At this time, the sheet assembly 200 gradually slides out of the packaging box 100 under the influence of gravity under the support of the block 34.

[0102] Based on the above structure, a third guide rail 73 is provided on one of the flaps 32 and the support block 34, and a third slider 74 is provided on the other. The third slider 74 is slidably mounted on the third guide rail 73. Figure 4 As shown, a third guide rail 73 is provided on the flip plate 32, and a third slider 74 is provided on the support block 34. The guide rail and slider assembly can limit the sliding trajectory of the support block 34 relative to the flip plate 32.

[0103] As an optional embodiment, there may be multiple support blocks 34, and the supporting surfaces of the multiple support blocks 34 are coplanar. Of course, there may also be only one support block 34. The number of support blocks 34 can be adjusted according to the supporting requirements (e.g., the side length of the sheet assembly 200), and is not limited here.

[0104] In some embodiments, one, two, or more rolling elements are provided on the second platform 3; each rolling element is located on the flip plate 32 near one end of the first platform 2, and the sides of each rolling element that contact the sheet assembly 200 are collinear. The rolling elements can be balls or rollers. The arrangement of the rolling elements can prevent friction between the sheet assembly 200 and the second support surface, which helps the sheet assembly 200 fall from the packaging box 100 by gravity and slide onto the second support surface, while preventing wear on the side of the sheet assembly 200 near the second support surface. When the rolling element is a roller, it is preferable to use a rubber-coated roller, which can act as a buffer during contact with the sheet assembly 200, effectively preventing the sheet assembly 200 from bumping or wearing.

[0105] In some embodiments, refer to Figure 11 , Figure 12as well as Figure 14 The second platform 3 also includes a mounting plate 31 rotatably mounted on the frame 1 and a sixth drive assembly 35 mounted on the mounting plate 31; a flip plate 32 is rotatably mounted on the mounting plate 31, the rotation center line of the flip plate 32 relative to the mounting plate 31 is parallel to the rotation center line of the mounting plate 31 relative to the frame 1, and they are located on opposite sides of the flip plate 32. The sixth drive assembly 35 is drively connected to the flip plate 32 to drive the flip plate 32 to rotate relative to the mounting plate 31. The structure of the sixth drive assembly 35 is similar to that of the first drive assembly 5, and will not be described again here. Figure 14 As shown, the mounting plate 31 and the flip plate 32 are designed to push the sheet assembly 200 further out relative to the first frame 1, so as to facilitate subsequent processing of the sheet assembly 200.

[0106] In some embodiments, an arc-shaped guide assembly is provided between the mounting plate 31 and the flip plate 32, which can limit the rotational trajectory of the flip plate 32 relative to the mounting plate 31. Exemplarily, the arc-shaped guide assembly includes a guide plate 33 disposed on the flip plate 32 and a guide slider (obscured in the figure) disposed on the mounting plate 31. The guide plate 33 has an arc-shaped hole with the rotation axis of the flip plate 32 relative to the mounting plate 31 as its center, and the guide slider is slidably disposed within the arc-shaped hole. Since the guide slider can only slide within the arc-shaped hole, the rotational trajectory of the flip plate 32 relative to the mounting plate 31 can be limited.

[0107] In some embodiments, the unpacking mechanism further includes a first limiting structure and a second limiting structure, wherein: the first limiting structure is used to limit the first platform 2 to two extreme positions relative to the frame 1 before and after rotation; the second limiting structure is used to limit the second platform 3 to two extreme positions relative to the frame 1 before and after rotation. Both limiting structures can use mechanical and / or electrical limiting methods to limit the platform. Taking the first limiting structure as an example, when the first limiting structure uses mechanical limiting, it includes two limiting members disposed on the frame 1, located at opposite ends of the rotation trajectory of the first platform 2 relative to the frame 1; when the first platform 2 rotates to abut against one of the limiting members, the first platform 2 is forced to stop rotating due to the obstruction of the limiting member. When the first limiting structure uses electrical limiting, it includes two proximity switches disposed on the frame 1, with the detection ends of the two proximity switches located at opposite ends of the rotation trajectory of the first platform 2 relative to the frame 1; when the first platform 2 rotates to the point where one of the proximity switches is triggered, the first platform 2 stops rotating.

[0108] In some embodiments, continue to refer to Figure 10 and Figure 11The unpacking mechanism also includes a pushing assembly 6, which includes a pushing component 61 and a pushing component drive source. The pushing component 61 is slidably disposed on the second platform 3 (specifically, the flip plate 32) in a direction perpendicular to the second support surface. The pushing component drive source is configured to drive the pushing component 61 to slide, thereby changing the protrusion length of the pushing component 61 relative to the second support surface.

[0109] Optionally, the pusher drive source is a piston cylinder (specifically, it can be any one of an electric cylinder, pneumatic cylinder, or hydraulic cylinder) or a motor; the power output end of the pusher drive source can be directly connected to the pusher 61, or it can be indirectly connected to the pusher 61 through a linear transmission structure. For example, the pusher drive source is a pneumatic cylinder, the cylinder body of which is fixedly mounted on the second platform 3 (specifically, the flip plate 32), and the piston rod end of the pusher drive source is connected to the pusher 61.

[0110] In some embodiments, in the flap 32 and the pusher 61, one is provided with a second guide rail 72, and the other is provided with a second slider, the second slider being slidably disposed on the second guide rail 72. Figure 11 As shown, a second guide rail 72 is provided on the flip plate 32, and a second slider is provided on the flip plate 32.

[0111] In some embodiments, at least one pusher roller 62 is provided at one end of the pusher 61 that is in contact with the sheet assembly 200, and the mounting axis of each pusher roller 62 is perpendicular to the stacking direction of the sheet assembly 200; when there are two or more pusher rollers 62, the outer tangent surface of each pusher roller 62 on the side near the sheet assembly 200 is coplanar.

[0112] When there is one pusher roller 62, it is a long, cylindrical structure. When there are multiple pusher rollers 62 with the same outer diameter, they are coaxially mounted on the pusher member 61. When there are multiple pusher rollers 62 with different outer diameters, it is sufficient to ensure that the outer tangential surfaces of each pusher roller 62 are coplanar. When there are multiple pusher rollers 62, the outer diameter of each pusher roller 62 can be adjusted according to the required support force. For example, the diameter of the pusher roller 62 in the middle is larger than that of the pusher rollers at both ends, which can improve the support force on the sheet assembly 200. By setting a roller at the end of the pusher member 61 that contacts the sheet assembly 200, the pusher member 61 and the sheet assembly 200 make rolling contact, which can reduce the friction between the pusher member 61 and the sheet assembly 200 and prevent the pusher member 61 from wearing or scratching the sheet assembly 200. To further avoid damage to the two end surfaces of the sheet assembly 200, the pusher roller 62 is preferably a rubber-coated roller.

[0113] The pusher assembly 6 has multiple operating modes, such as:

[0114] One way the pusher assembly 6 works is as follows: during the process of the sheet assembly 200 sliding from the first support surface to the second support surface, the pusher 61 is controlled to protrude relative to the second support surface, so that the sheet assembly 200 can be smoothly moved to the second support surface; after the sheet assembly 200 has been completely moved to the second support surface, the pusher 61 is controlled to retract to the side of the second support surface away from the sheet assembly 200, so that the sheet assembly 200 is in close contact with the second support surface.

[0115] Another way of working the pusher assembly 6 is as follows: after the sheet assembly 200 is completely moved to the second support surface, the pusher 61 is controlled to move relative to the second platform 3 to increase or decrease the protrusion length of the pusher 61 relative to the second support surface. At this time, the sheet assembly 200 moves, rotates or swings relative to the second support surface under the push of the pusher 61.

[0116] During the unpacking process, the working mode of the pusher assembly 6 can be selected according to the processing requirements of the sheet assembly 200.

[0117] In some embodiments, continue to refer to Figure 10 and Figure 11 The unpacking mechanism also includes a support assembly 9, which includes a support member 91 and a support member drive source. The support member 91 is slidably disposed on the second platform 3 in a direction perpendicular to the second support surface. The support member drive source is configured to drive the support member 91 to slide, thereby changing the protrusion length of the support member 91 relative to the second support surface. The support assembly 9 and the pusher assembly 6 can jointly support the sheet assembly 200. Further, at least one support roller 92 is provided at the end of the support member 91 that contacts the sheet assembly 200. The structure and operation of the support assembly 9 are the same as or similar to those of the pusher assembly 6, and will not be described in detail here.

[0118] Based on the above structure, the pusher 61 and the support 91 are arranged sequentially on the flip plate 32 in a direction away from the first platform 2. The pusher 61 is located at one end of the flip plate 32 near the first platform 2, and the pusher roller 62 on the pusher 61 acts as the rolling element described above. The support 91 is located in the middle of the flip plate 32, and the flip plate 32 has a notch for the support 91 to pass through.

[0119] When the protrusion length of the pusher 61 relative to the second support surface is the same as that of the support 91 relative to the second support surface, the sheet assembly 200 is parallel to the second support surface (in this embodiment, the surface of the flap 32 close to the sheet assembly 200 can be understood as the second support surface); at this time, controlling the pusher 61 and the support 91 to slide synchronously relative to the flap 32 can push the sheet assembly 200 closer to or further away from the second support surface. When the protrusion length of the pusher 61 relative to the second support surface is different from that of the support 91 relative to the second support surface, the sheet assembly 200 is tilted relative to the second support surface; thus, by controlling the difference between the protrusion lengths of the pusher 61 and the support 91 relative to the second support surface, the angle between the sheet assembly 200 and the second support surface can be adjusted.

[0120] This application also provides an unpacking method applied to the unpacking mechanism provided in the above embodiments, the unpacking method comprising the following steps:

[0121] S1. The seal of the packaging box 100 is opened manually or by using an opening mechanism, so that an opening is formed on the side of the packaging box 100 that is perpendicular to the stacking direction of the sheet assembly 200.

[0122] S2, Loading: Refer to... Figure 1 With the first support surface in a horizontal state, the packaging box 100 containing the sheet assembly 200 is placed on the first support surface manually or by using a packaging box transfer mechanism. The packaging box 100 containing the sheet assembly 200 is limited by a limiting structure. The opening of the limited packaging box 100 is oriented horizontally and towards the two interlocking fingers.

[0123] S3, Material Retrieval:

[0124] S31, Barrier Protective Layer: Refer to [reference needed] Figure 1 The base plate 23 is kept stationary relative to the support plate 22, and the forked finger assembly 4 is controlled to slide relative to the support plate 22 in a direction close to the base plate 23, so that both forked fingers are inserted into the packaging box 100 and located on the upper and lower sides of the sheet assembly 200 respectively. At this time, the first forked finger 41 and the second forked finger 42 can block the packaging box 100 and the protective layer inside the box, so that the packaging box 100 is restricted on the first support surface during the process of the sheet assembly 200 sliding out of the packaging box 100, and the protective layer is trapped inside the packaging box 100.

[0125] S32, supporting material: refer to Figure 1 and Figure 2When both the first support surface and the second support surface are in a horizontal state, the fork finger assembly 4 and the base plate 23 are controlled to slide synchronously relative to the support plate 22 in the direction close to the second platform 3, and the support block 34 is controlled to slide relative to the flip plate 32 in the direction close to the first platform 2, so that the support block 34 moves to the opening of the packaging box 100.

[0126] S33, the sheet assembly slides out: refer to... Figure 3 and Figure 13 The system controls the first platform 2 to rotate relative to the frame 1 and drive the packaging box 100 to rotate, so that the first support surface forms an angle α with respect to the horizontal plane and the opening of the packaging box 100 faces downward. Before or while the first platform 2 rotates, the system controls the second platform 3 to rotate around the second horizontal center line, so that the second support surface forms an angle α with respect to the horizontal plane. When both the first and second support surfaces form an angle α with respect to the horizontal plane, the sheet assembly 200 inside the packaging box 100 slides out from the opening to the second support surface under the action of gravity. During the sliding process of the sheet assembly 200 relative to the second support surface, the system controls the support block 34 to move backward along the sliding path of the sheet assembly 200, and the sheet assembly 200 gradually slides out of the packaging box 100 under the influence of gravity under the support of the support block 34.

[0127] S4, Protective Layer Confirmation: Refer to... Figure 4 The protective layer is visually inspected or determined using a visual inspection system to determine whether it slides out with the sheet assembly 200. If the protective layer slides out with the sheet assembly 200, the protective layer is removed from the sheet assembly 200.

[0128] S5, Packaging box reset: Refer to... Figure 5 The first platform 2 is controlled to rotate relative to the frame 1 and drive the packaging box 100 to rotate, so that the first support surface is in a horizontal state and the opening of the packaging box 100 faces the horizontal direction. Then, the packaging box 100 is removed from the first platform 2 manually or by using the packaging box transfer mechanism.

[0129] S6, reservation: see reference Figure 6 and Figure 14 The control flap 32 rotates relative to the mounting plate 31, making the angle between the second support surface and the horizontal plane larger. At this time, the sheet assembly 200 can be in an upright state or in an inclined state.

[0130] S7: Image processing: Reference Figure 6 The sheet group 200, which is in a non-horizontal state (it can be in a vertical state or an inclined state), is regulated so that the individual sheets in the sheet group 200 overlap in the stacking direction.

[0131] S8, Circulation: Refer to Figure 7The control flap 32 is rotated relative to the mounting plate 31 until they are parallel. Then, the control flap 32 and the mounting plate 31 are rotated simultaneously relative to the frame 1 so that the second support surface and the sheet assembly 200 on it are in a horizontal state, so as to facilitate the transfer of the sheet assembly 200 to the next process.

[0132] Example 2

[0133] The difference between the unpacking mechanism provided in this embodiment and that in Embodiment 1 is that, in this embodiment, the second platform 3 includes a flap 32 rotatably mounted on the frame. The end of the flap 32 away from the first platform 2 has a support portion perpendicular to the flap 32, and the surface of the support portion facing the first platform 2 is a supporting surface. The structure of the support portion is similar to the support block 34 in Embodiment 1, but unlike the support block 34, the support portion is fixedly mounted on the flap 32. In some embodiments, the support portion is detachably mounted on the flap 32 using fasteners. In other embodiments, the support portion and the flap 32 are integrally formed.

[0134] Example 3

[0135] The difference between the unpacking mechanism provided in this embodiment and that in Embodiment 1 is that this embodiment does not include the second platform 3; in this embodiment, the unpacking mechanism further includes a receiving device, which is configured to receive the sheet assembly 200 that slides out from the packaging box 100. For example, refer to... Figure 15 The receiving device is a disc structure with a notch on one side. The receiving device is positioned along the sliding path of the sheet assembly 200, with the notch facing the packaging box 100. This allows the sheet assembly 200 to enter the receiving device through the notch after sliding out of the packaging box 100. Furthermore, to prevent the receiving device from bumping or abrading the sheet assembly 200, a cushioning structure is provided inside the receiving device; exemplarily, the cushioning structure is a cushioning pad attached to the inner wall of the receiving device.

[0136] The orientation of the notch in the receiving device can be adjusted manually or by a drive assembly. In an embodiment where the orientation of the notch is adjusted by a drive assembly, the unpacking mechanism further includes an eighth drive assembly. The power output end of the eighth drive assembly is connected to the receiving device, and the eighth drive assembly is configured to drive the receiving device to rotate relative to the frame 1. When it is necessary to receive the sheet assembly 200, the eighth drive assembly is controlled to drive the receiving device to rotate relative to the frame 1, so that the notch of the receiving device is aligned with the opening of the packaging box 100. Thus, after the sheet assembly 200 slides out of the opening of the packaging box 100, it slides back into the receiving device through the notch. After the receiving device receives the sheet assembly 200, the eighth drive assembly is controlled to drive the receiving device to rotate relative to the frame 1, so that the notch of the receiving device faces horizontally, and the sheet assembly 200 inside the receiving device is in a horizontal state to facilitate the subsequent circulation of the sheet assembly 200.

[0137] In some embodiments, the receiving device can be placed on the frame 1. After the receiving device receives the sheet assembly 200, the receiving device can be removed from the frame 1 and transferred to the next process.

[0138] Example 4

[0139] This embodiment provides a packaging unpacking device, as shown in the following example. Figure 16 and Figure 17 The unpacking device includes two unpacking mechanisms as described in Embodiment 1 or Embodiment 2. The two unpacking mechanisms are arranged opposite each other with the vertical plane as the center of symmetry, and the two unpacking mechanisms can approach or move away from each other in the horizontal direction.

[0140] When the two second platforms 3 are rotated to the point where both second support surfaces are in an upright state, a first gap I can be formed between the pushing components 6 of the two unpacking mechanisms for placing the sheet group 200 in a non-horizontal state, and the pushing components 6 of the two unpacking mechanisms are configured to alternately push the sheet group 200 in the gap I so that the sheet group 200 swings left and right relative to the upright surface.

[0141] It should be noted that in embodiments where the second platform 3 is provided with a support or support block 34, the support or support block 34 of the two second platforms 3 is staggered to avoid interference between them. Specifically, each second platform 3 is provided with multiple supports 34. With a first gap I formed between the material pushing components 6 of the two unpacking mechanisms, the supports 34 of the two second platforms 3 interlock and jointly support the sheet assembly 200 below. During the swinging process of the sheet assembly 200, the lower end of the sheet assembly 200 rests on the support block 34, and its upper end swings left and right under the push of the two sets of material pushing components 6.

[0142] In some embodiments, the unpacking device further includes a mounting platform and a seventh drive assembly; the frame 1 of one unpacking mechanism is fixedly mounted on the mounting platform, and the frame 1 of the other unpacking mechanism is slidably mounted on the mounting platform; the power output end of the seventh drive assembly is connected to the frame 1 slidably mounted on the mounting platform to drive the two frames 1 to approach or move away from each other in the horizontal direction.

[0143] In an embodiment where the unpacking mechanism includes a support component 9, when a first gap I is formed between the pushing components 6 of the two unpacking mechanisms, a second gap U can be formed between the support components 9 of the two unpacking mechanisms located below the first gap I. During the swinging process of the sheet assembly 200, the position of the second gap U in the horizontal direction remains unchanged, while the first gap I moves laterally in the horizontal direction. Thus, the lower end of the sheet assembly 200 can be limited by the second gap U, causing the upper end of the sheet assembly 200 to swing left and right while its lower end remains stationary.

[0144] The unpacking method applied to the above-mentioned unpacking equipment is roughly the same as the unpacking method provided in Embodiment 1. The main differences are: (1) Before controlling the second platform 3 of one of the unpacking mechanisms to rotate relative to the frame 1, the two unpacking mechanisms are controlled to move away from each other to the maximum distance so that the second platform 3 of one of the unpacking mechanisms will not interfere with the other unpacking mechanism during rotation; (2) In the pre-positioning step: while controlling the flip plate 32 to rotate relative to the mounting plate 31, the two unpacking mechanisms are controlled to move closer to each other to the minimum distance so that the pushing components 6 of the two unpacking mechanisms form a first gap. (2) In the first gap I, the sheet group 200 is pushed by each pusher 61 and each support 91 to make the sheet group 200 in the first gap I stand upright; (3) In the sheet sorting step: the pusher components 6 of the two unpacking mechanisms are controlled to push the sheet group 200 in the first gap I alternately so that the sheet group 200 swings left and right relative to the vertical surface; (4) In the circulation step: while controlling the flip plate 32 to rotate relative to the mounting plate 31, the two unpacking mechanisms are controlled to move away from each other to the maximum distance so that the second platform 3 will not interfere with the other unpacking mechanism during the rotation relative to the frame 1.

[0145] As described above, the unpacking equipment provided in this application, after removing the sheet assembly 200 from the packaging box 100, uses two unpacking mechanisms in cooperation to swing the sheet assembly 200, causing misalignment between adjacent sheets and thus dispersing the sheet assembly 200. After swinging, due to the relatively dispersed arrangement of the sheets, the friction between them is very small, thus preventing excessive pressure on the sheets during subsequent centering and straightening, avoiding sheet breakage or fragmentation, and improving the sheet sorting effect. Furthermore, while one unpacking mechanism is performing the material handling and sorting step, the other unpacking mechanism can perform the material loading step, thereby improving the efficiency of unpacking and material handling.

[0146] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
