Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum frame conveying, and specifically relates to a handling device for adding aluminum frames to the bottom of a stack, and more particularly to a photovoltaic lightweight aluminum frame handling device and a working method thereof. Background Art

[0002] In the production process of photovoltaic modules, the handling and stacking of lightweight aluminum frames is one of the key processes.

[0003] In related technologies, aluminum frame handling equipment usually relies on a high-precision six-axis manipulator combined with a visual positioning system to achieve aluminum frame grasping and positioning. However, such equipment has the following problems:

[0004] First, the six-axis robot needs to be equipped with a high-resolution industrial camera, a laser rangefinder and complex motion control algorithms, which increases the cost of the production line.

[0005] Second, the aluminum frames must meet a positioning accuracy of ±0.15mm when stacked at the bottom of the loading box, further increasing the accuracy requirements for the six-axis robot.

[0006] Third, due to cost control, the lightweight aluminum frame is thinned, resulting in a soft texture. When clamped by traditional double-sided V-blocks, the corners of the aluminum frame are prone to plastic deformation, resulting in an increase in the stacking misalignment rate. Therefore, the center of the aluminum frame cannot be adjusted using alignment tooling. Only a high-precision six-axis robotic arm can be used to directly send the aluminum frame to the bottom of the loading box to complete the stacking.

[0007] Therefore, how to complete the stacking of soft and lightweight aluminum frames while reducing the precision requirements of the robotic arm is a technical problem that needs to be solved urgently.

[0008] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art. Summary of the Invention

[0009] The embodiments of the present disclosure at least provide a photovoltaic lightweight aluminum frame handling device and a working method thereof.

[0010] In a first aspect, an embodiment of the present disclosure provides a photovoltaic lightweight aluminum frame handling device, comprising:

[0011] Double-axis feeding mechanism, which is used to absorb and grab the aluminum frame;

[0012] An auxiliary centering mechanism, which is used to adjust the center position of the aluminum frame placed by the dual-axis feeding mechanism;

[0013] A loading box, the bottom of which is provided with a loading port for stacking aluminum frames;

[0014] Among them, the auxiliary centering mechanism includes:

[0015] Lifting platform;

[0016] A square center plate, with guide plates rotatably provided on both sides thereof, and the guide plates are used to adjust the center position of the inner frame of the aluminum frame that falls into the square center plate;

[0017] A driving cylinder, which is arranged below the lifting platform;

[0018] The control module is configured to control the driving cylinder to drive the lifting platform to rise, thereby delivering the centered aluminum frame into the loading port at the bottom of the loading box to complete the stacking of the aluminum frames.

[0019] In an optional embodiment, the width of the square center plate is adapted to the width of the inner wall of the aluminum frame;

[0020] The guide plates extend outward along the length direction of the square center plate, and the distance between the two guide plates is greater than the inner length of the aluminum frame;

[0021] When the aluminum frame falls into the auxiliary centering mechanism, the inner walls of the aluminum frame respectively abut against the side walls corresponding to the square centering plate and the top surfaces of the two guide plates. Under the action of the gravity of the aluminum frame, the guide plates are pressed to tilt and flip downward until the aluminum frame completely passes over the guide plates, completing the adjustment of the center position of the aluminum frame.

[0022] In an optional embodiment, the length of the square center plate is m;

[0023] The length of the inner wall of the aluminum frame is L;

[0024] The thickness of the guide plate is n;

[0025] Wherein, L=m+2n, that is, when the guide plate tilts downward and flips to abut against the side wall of the guide plate, the inner wall of the aluminum frame is completely in contact with the side wall corresponding to the square center plate and the surface of the guide plate.

[0026] In an optional embodiment, the guide plate is hinged to the end of the square center plate via a first rotating shaft;

[0027] Wherein, a first return torsion spring is provided on the first rotating shaft;

[0028] When the first return torsion spring is in a natural state, the top surface of the guide plate is parallel to the top surface of the square center plate.

[0029] In an optional embodiment, the auxiliary centering mechanism further includes a holding motor;

[0030] The abutting motor is embedded in the top surface of the lifting platform, and the abutting block of the abutting motor is exposed from the top surface of the lifting platform and is located below the guide plate;

[0031] After the aluminum frame completely passes over the guide plate, the control module is further configured to drive the abutment motor to drive the abutment block to rise, thereby driving the aluminum frame to rise until it abuts against the bottom surface of the guide plate.

[0032] In an optional embodiment, the loading box includes:

[0033] frame;

[0034] a bottom plate, which is arranged at the bottom of the frame, and the loading port is opened on the bottom plate;

[0035] A support plate is rotatably provided on the top surface of the bottom plate, and the support plate is arranged toward the frame;

[0036] After the aluminum frame rises to abut against the bottom surface of the guide plate, the control module is also configured to control the driving cylinder to drive the lifting platform to rise, pushing the support plate to flip outward until the aluminum frame passes over the support plate, and then completing the stacking of the aluminum frame through the cooperation of the driving cylinder and the abutting motor.

[0037] In an optional embodiment, the stacking of the aluminum frames is completed by cooperating with the driving cylinder and the holding motor, that is:

[0038] The control module drives the supporting block of the supporting motor to descend, thereby releasing the support for the aluminum frame;

[0039] The stacked aluminum frames drive the guide plates to tilt and flip downward until they abut against the side walls of the guide plates;

[0040] The control module controls the driving cylinder to descend, so that the support plate is reset, and the bottom of the stacked aluminum frame is supported to complete the stacking of the aluminum frame;

[0041] The control module controls the reset of the auxiliary centering mechanism.

[0042] In an optional embodiment, the support plate is rotatably connected to the top surface of the base plate via a second rotating shaft;

[0043] Furthermore, a second return torsion spring is provided on the second rotating shaft;

[0044] When the second return torsion spring is in a natural state, the top surface of the support plate is parallel to the top surface of the bottom plate.

[0045] In an optional embodiment, the dual-axis feeding mechanism includes:

[0046] Horizontal moving part;

[0047] a vertical moving portion, which is arranged on the horizontal moving portion;

[0048] The vacuum adsorption claw is arranged at the end of the vertical moving part and is used for adsorbing and grabbing the aluminum frame.

[0049] In a second aspect, the embodiments of the present disclosure further provide a working method applied to the above-mentioned photovoltaic lightweight aluminum frame handling equipment, the working method comprising:

[0050] The dual-axis loading mechanism absorbs and grabs the aluminum frame;

[0051] The grabbed aluminum frame is sent into the auxiliary centering mechanism to adjust the center position;

[0052] The auxiliary centering mechanism sends the aluminum frame after adjusting the center position into the loading box, completing the transportation of the aluminum frame.

[0053] The beneficial effect of the present invention is that the photovoltaic lightweight aluminum frame handling equipment and its working method adopt a dual-axis loading mechanism to replace the traditional six-axis manipulator. When the external conveyor belt transports the aluminum frame to the bottom of the dual-axis loading mechanism, one of the side edges of the aluminum frame is unilaterally positioned, thereby reducing the cost of the dual-axis loading mechanism. At the same time, in conjunction with the auxiliary centering mechanism, the other side edge of the aluminum frame is adjusted, thereby adjusting the center position of the inner frame of the aluminum frame. This reduces the accuracy requirements of the dual-axis loading mechanism while meeting the docking accuracy, and also avoids deformation of the aluminum frame when the center position is adjusted.

[0071] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0072] In this document, when it is mentioned that a first component is located on a second component, this may mean that the first component may be directly formed on the second component, or that a third component may be interposed between the first component and the second component. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe technical content.

[0073] As used herein, when an element or layer is referred to as being "located on," "engaged to," "connected to," "attached to," or "coupled to" another element or layer, it may be directly located on, engaged, connected, attached to, or coupled to the other element or layer, or there may be intervening elements or layers. Conversely, when an element is referred to as being "directly on," "directly engaged to," "directly connected to," "directly attached to," or "directly coupled to" another element or layer, there may be no intervening elements or layers. Other words used to describe the relationship between elements should be interpreted in a similar manner (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.). As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0074] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." when following a list of elements modify the entire list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0075] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limiting. As used herein, the singular articles "a", "an" and "the" may also be intended to include plural forms, unless otherwise clearly indicated herein.

[0076] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Thus, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations, aspects, or designs. Instead, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0077] Research has found that in related technologies, when stacking soft aluminum frames, in order to avoid affecting the corners of the aluminum frames (for example, deformation), double-sided V-block clamping is generally not used. Instead, a high-precision six-axis robotic arm is selected to directly send the aluminum frames to the bottom of the loading frame for stacking, resulting in excessively high stacking costs for the aluminum frames.

[0078] Based on the above research, the embodiment of the present disclosure provides a photovoltaic lightweight aluminum frame handling equipment and its working method, which uses a dual-axis loading mechanism to replace the traditional six-axis manipulator, and cooperates with an auxiliary centering mechanism to adjust the other side of the aluminum frame, thereby meeting the docking accuracy while reducing the accuracy requirements of the dual-axis loading mechanism.

[0079] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0080] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0081] See also Figure 1 and Figure 2 At least one embodiment provides a photovoltaic lightweight aluminum frame handling device, including: a dual-axis loading mechanism 100, which is used to absorb and grasp the aluminum frame 400; an auxiliary centering mechanism 200, which is used to adjust the center position of the aluminum frame 400 placed by the dual-axis loading mechanism 100; a loading box 300, the bottom of which is provided with a loading port 321 for stacking the aluminum frames 400; wherein the auxiliary centering mechanism 200 includes: a lifting platform 210; a square centering plate 220, both sides of which are rotatably provided with guide plates 240, and the guide plates 240 are used to adjust the center position of the inner frame of the aluminum frame 400 that falls into the square centering plate 220; a driving cylinder 230, which is arranged below the lifting platform 210; a control module, which is configured to control the driving cylinder 230 to drive the lifting platform 210 to rise, thereby sending the centered aluminum frame 400 into the loading port 321 at the bottom of the loading box 300, completing the stacking of the aluminum frames 400.

[0082] A dual-axis loading mechanism 100 is used instead of the traditional six-axis robot. When the external conveyor belt transports the aluminum frame 400 to the bottom of the dual-axis loading mechanism 100, one of the side edges of the aluminum frame 400 is unilaterally positioned to reduce the cost of the dual-axis loading mechanism 100. At the same time, in conjunction with the auxiliary centering mechanism 200, the other side edge of the aluminum frame 400 is adjusted, thereby adjusting the center position of the inner frame of the aluminum frame 400. This reduces the accuracy requirements of the dual-axis loading mechanism 100 while meeting the docking accuracy, and also avoids deformation of the aluminum frame 400 when the center position is adjusted.

[0083] See also Figure 2 and Figure 3 , the width of the square center plate 220 (such as Figure 2 The guide plate 240 extends outward along the length direction of the square center plate 220, and the distance between the two guide plates 240 (as shown in a) is adapted to the width of the inner wall of the aluminum frame 400; Figure 2 (as shown in b)) is greater than the inner length of the aluminum frame 400; when the aluminum frame 400 falls into the auxiliary centering mechanism 200, the inner wall of the aluminum frame 400 respectively abuts against the side walls corresponding to the square centering plate 220 and the top surfaces of the two guide plates 240, and under the action of the gravity of the aluminum frame 400, the guide plates 240 are pressed to tilt downward (as shown in Figure 5 as shown), until the aluminum frame 400 completely passes over the guide plate 240, completing the adjustment of the center position of the aluminum frame 400.

[0084] The guide plate 240 is flipped by triggering the weight of the aluminum frame 400 itself, thereby achieving unpowered automatic centering adjustment, thereby avoiding deformation of the aluminum frame 400 caused by excessive stress.

[0085] See also Figure 3Specifically, the length of the square centering plate 220 is m; the length of the inner wall of the aluminum frame 400 is L; and the thickness of the guide plate 240 is n. Here, L = m + 2n. That is, when the guide plate 240 tilts downward and abuts against the sidewalls of the guide plate 240, the inner wall of the aluminum frame 400 completely conforms to the corresponding sidewalls of the square centering plate 220 and the surface of the guide plate 240. By precisely defining the dimensions of L, m, and n, the centering accuracy is improved, ensuring the accuracy of the aluminum frame 400 stacking, reducing the precision requirements of the loading mechanism, and thus lowering production line costs.

[0086] See also Figure 2 and Figure 3 The guide plate 240 is hinged to the end of the square center plate 220 via a first rotating shaft 241; wherein, a first return torsion spring (not shown) is provided on the first rotating shaft 241; when the first return torsion spring is in a natural state, the top surface of the guide plate 240 is parallel to the top surface of the square center plate 220 (as shown in FIG. Figure 4 shown).

[0087] The guide plate 240 is reset by the first reset torsion spring. After the aluminum frame 400 completely passes over the guide plate 240 , the first reset torsion spring drives the guide plate 240 to return to a natural state, thereby completing the reset of the guide plate 240 .

[0088] Among them, the auxiliary centering mechanism 200 also includes a supporting motor 250; the supporting motor 250 is embedded in the top surface of the lifting platform 210, and the supporting block 251 of the supporting motor 250 is exposed from the top surface of the lifting platform 210 and is located below the guide plate 240; after the aluminum frame 400 completely passes over the guide plate 240, the control module is further configured to drive the supporting motor 250 to drive the supporting block 251 to rise, thereby driving the aluminum frame 400 to rise until it is in contact with the bottom surface of the guide plate 240, as shown in FIG. Figure 6 shown.

[0089] It should be noted that, in a preferred embodiment, the supporting block 251 supporting the motor 250 is in the shape of an elongated strip, and a flexible layer is provided on the top surface of the supporting block 251 to prevent the aluminum frame 400 from being deformed.

[0090] Specifically, the aluminum frame 400 along Figure 4 The direction shown by F in the middle falls on the square center plate 220 until the inner wall of the aluminum frame 400 respectively abuts against the side wall corresponding to the square center plate 220 and the top surface of the two guide plates 240. Figure 5As shown, the aluminum frame 400 continues to fall, and after passing over the guide plate 240, the guide plate 240 rebounds under the action of the first return torsion spring, and the control module drives the abutting motor 250 to drive the abutting block 251 to rise, driving the aluminum frame 400 to rise until it abuts against the bottom surface of the guide plate 240, as shown in FIG. Figure 6 shown.

[0091] See also Figure 2 The loading box 300 includes: a frame body 310; a bottom plate 320, which is arranged at the bottom of the frame body 310, and the loading port 321 is opened on the bottom plate 320; a support plate 330 is rotatably provided on the top surface of the bottom plate 320, and the support plate 330 is arranged toward the inside of the frame body 310.

[0092] It should be noted that a flexible layer is provided on the support plate 330 to avoid scratching the aluminum frame 400 .

[0093] After the aluminum frame 400 rises to abut against the bottom surface of the guide plate 240, Figure 7 As shown, the control module is further configured to control the driving cylinder 230 to drive the lifting platform 210 to rise, and push the support plate 330 to flip outward, as shown in FIG. Figure 8 As shown, after the aluminum frame 400 passes over the support plate 330 , the stacking of the aluminum frame 400 is completed by the cooperation between the driving cylinder 230 and the holding motor 250 .

[0094] Specifically, after the aluminum frame 400 passes over the support plate 330, the support plate 330 falls back and is stuck between the square center plate 220 and the aluminum frame 400. Figure 9 As shown, it supports the subsequent stacking of aluminum frames 400.

[0095] The stacking of the aluminum frame 400 is completed by driving the cylinder 230 and the supporting motor 250, that is, the control module drives the supporting block 251 of the supporting motor 250 to descend, releasing the support for the aluminum frame 400. Figure 10 The stacked aluminum frame 400 drives the guide plate 240 to tilt downward and flip to abut against the side wall of the guide plate 240, as shown Figure 11 The control module controls the drive cylinder 230 to descend, so that the support plate 330 is reset, and the bottom support of the stacked aluminum frame 400 is completed to complete the stacking of the aluminum frame 400, as shown Figure 12 As shown; the control module controls the auxiliary centering mechanism 200 to reset.

[0096] It should be noted that, in order to limit the falling path of the support plate 330, in a preferred embodiment, the support plate 330 is rotatably connected to the top surface of the base plate 320 via a second rotating shaft 331; and, a second return torsion spring 332 is provided on the second rotating shaft 331; when the second return torsion spring 332 is in a natural state, the top surface of the support plate 330 is parallel to the top surface of the base plate 320, thereby continuing to support the stacked aluminum frame 400.

[0097] See also Figure 1 The dual-axis loading mechanism 100 includes a horizontal moving portion 110; a vertical moving portion 120 mounted on the horizontal moving portion 110; and a vacuum suction claw 130 disposed at the end of the vertical moving portion 120 for suction-gripping the aluminum frame 400. By replacing the traditional six-axis robot with the dual-axis loading mechanism 100, the aluminum frame 400 is positioned on one side of the mechanism as the external conveyor belt delivers it to the bottom of the dual-axis loading mechanism 100, reducing the cost of the dual-axis loading mechanism 100.

[0098] See also Figure 13 The present disclosure also provides a working method for the above-mentioned photovoltaic lightweight aluminum frame handling equipment, the working method comprising:

[0099] S110: The dual-axis loading mechanism 100 performs suction and grabbing on the aluminum frame 400;

[0100] S120: The grasped aluminum frame 400 is sent to the auxiliary centering mechanism 200 to adjust the center position;

[0101] S130 : The auxiliary centering mechanism 200 sends the aluminum frame 400 after adjusting the center position into the loading box 300 , completing the transportation of the aluminum frame 400 .

[0102] The beneficial effect of the present invention is that the present invention provides a photovoltaic lightweight aluminum frame handling device and a working method thereof, wherein the photovoltaic lightweight aluminum frame handling device includes: a dual-axis loading mechanism 100, which is used to absorb and grab the aluminum frame 400; an auxiliary centering mechanism 200, which is used to adjust the center position of the aluminum frame 400 placed by the dual-axis loading mechanism 100; a loading box 300, the bottom of which is provided with a loading port 321 for stacking the aluminum frames 400; wherein the auxiliary centering mechanism 200 includes: a lifting platform 210; a square centering plate 220, with guide plates 240 rotatably provided on both sides thereof, and the guide plates 240 are used to adjust the center position of the inner frame of the aluminum frame 400 that falls into the square centering plate 220; a driving cylinder 230, which is arranged below the lifting platform 210; a control module, configured to control the driving cylinder 230 to drive the lifting platform 210 to rise, thereby delivering the centered aluminum frame 400 into the loading port 321 at the bottom of the loading box 300, thereby completing the stacking of the aluminum frames 400. A dual-axis loading mechanism 100 is used instead of the traditional six-axis robot. When the external conveyor belt transports the aluminum frame 400 to the bottom of the dual-axis loading mechanism 100, one of the side edges of the aluminum frame 400 is unilaterally positioned to reduce the cost of the dual-axis loading mechanism 100. At the same time, in conjunction with the auxiliary centering mechanism 200, the other side edge of the aluminum frame 400 is adjusted, thereby adjusting the center position of the inner frame of the aluminum frame 400. This reduces the accuracy requirements of the dual-axis loading mechanism 100 while meeting the docking accuracy, and also avoids deformation of the aluminum frame 400 when the center position is adjusted.

[0103] In the description of the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0104] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, terms such as "first", "second" and other numerical terms do not imply an order or sequence when used herein unless expressly indicated above. Therefore, without departing from the teachings of the example embodiments, the first element, component, region, layer or section discussed above may be referred to as a second element, component, region, layer or section.

[0105] Spatially relative terms, such as "inside," "outside," "below," "beneath," "down," "above," "on," etc., may be used herein to describe the relationship of one element or feature to another element or feature as illustrated in the figures. In addition to the orientations depicted in the figures, spatially relative terms may be intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as being "below" or "below" other elements or features will be oriented to be "above" the other elements or features.
