Description

Technical Field

[0001] This invention relates to the field of photovoltaic module technology, specifically to an automatic photovoltaic module foot wrapping machine and method. Background Technology

[0002] A photovoltaic (PV) panel is a device that directly converts light energy into electrical energy using the photovoltaic effect. It is usually composed of multiple solar cells connected in series or parallel. During the production and transportation of PV panels, corner protectors are usually installed at the corners to prevent them from being hit and worn. These corner protectors are typically made of paper, such as kraft paper or yarn tube paper. Paper corner protectors are relatively lightweight, easy to handle and operate, and have low cost. The raw materials are relatively inexpensive, and the manufacturing process is relatively simple, making them economical. At the same time, paper is a recyclable material, which meets environmental protection requirements.

[0003] Chinese patent CN219193146U discloses a corner-wrapping device suitable for solar photovoltaic modules, including a base plate. A control panel is installed on the right side of the top of the base plate, a movable seat is installed in the middle of the top of the base plate, a worm gear is installed on the top of the movable seat, and a drive mechanism is installed on the left side of the top of the base plate. The left side of the worm gear is connected to the drive mechanism. By continuously rotating a first motor, the corner-wrapping structure can be controlled to move up and down, allowing it to be precisely positioned at the height of the photovoltaic module's corner. By controlling a second motor to drive the worm gear to rotate, the worm gear meshes with the worm gear, driving the support frame to rotate. This allows adjustment of the corner-wrapping structure's angle, enabling it to accurately fit onto the outside of the photovoltaic module. This achieves precise positioning of the corner-wrapping module and facilitates protection of the photovoltaic module's corners.

[0004] However, the technical solution of this patent has the following problems:

[0005] 1. This patent uses the continuous rotation of a first motor to control the up-and-down movement of the corner protector structure, enabling the corner protector structure to be precisely moved to the height of the photovoltaic module's corner. By controlling a second motor to drive the worm gear to rotate, the worm gear meshes with the worm wheel, driving the support frame to rotate, thereby adjusting the angle of the corner protector structure. This allows the corner protector structure to be accurately fitted onto the outside of the photovoltaic module, achieving precise positioning of the corner protector module. However, it can only fit one corner protector at a time and cannot install corner protectors on all four corners of the photovoltaic module simultaneously, resulting in low corner protector efficiency.

[0006] 2. This patent cannot automatically bend L-shaped paper into paper corner protectors; it can only use pre-made corner protectors for installation, and it cannot achieve automatic feeding of corner protectors, resulting in relatively low production efficiency.

[0007] Based on this, the present invention designs an automatic protective foot machine and method for photovoltaic modules to solve the above problems. Summary of the Invention

A protrusion is provided on the right side of the paper limiting plate to limit the L-shaped paper and prevent it from shifting.

[0013] Furthermore, the secondary folding mechanism includes: a rotating plate and a second stepper motor. The second stepper motor is fixedly mounted on the side wall of the flipping bracket.

The lifting mechanism can be configured as a servo lifting mechanism.

[0015] Furthermore, the corner protector pressing device includes a conveying mechanism and a pressing mechanism, wherein the conveying mechanism is installed on the left side of the side bracket and the pressing mechanism is installed on the right side of the conveying mechanism.

[0016] Furthermore, the conveying mechanism includes: a first slide cylinder, a second slide cylinder, and a suction cup. The first slide cylinder is fixedly installed on the rear side of the side support via a bracket. The second slide cylinder is fixedly installed on the output end of the first slide cylinder. The suction cup is fixedly installed on the output end of the second slide cylinder.

[0017] Furthermore, the pressing mechanism includes: an extension bracket, a pressure plate, a first dual-axis cylinder, and an insertion plate. The extension bracket is fixedly mounted on the bracket of the first slide cylinder. The pressure plate is fixedly mounted on the lower side of the extension bracket.

The insertion plate is fixedly mounted on the output end of the first dual-axis cylinder.

[0018] Furthermore, the material blocking device includes: a second dual-axis cylinder, a stop bar, and a second proximity sensor. The second dual-axis cylinder is fixedly installed on the lower side of the frame, and multiple stop bars are fixedly installed on the output end of the second dual-axis cylinder via brackets. The second proximity sensor is fixedly installed on the upper side of the frame for detecting whether the photovoltaic panel is close.

[0019] To better achieve the objectives of this invention, this invention also provides a method for an automatic protective sleeve machine for photovoltaic modules, comprising the following steps:

[0020] Step 1: Place the L-shaped paper sheet on the L-shaped moving plate of the paper sheet feeding device. The output end of the second slide cylinder moves downward, driving the suction cup to move downward. The suction cup moves downward and picks up the L-shaped paper sheet. The output end of the second slide cylinder moves upward, driving the suction cup to move upward. The output end of the first slide cylinder moves to the right, driving the second slide cylinder and the suction cup to move to the right. The second slide cylinder and the suction cup move to the right, driving the L-shaped paper sheet on the suction cup to the irregular support of the first folding mechanism. The output end of the second slide cylinder moves downward, driving the suction cup to move downward. The suction cup moves downward and places the L-shaped paper sheet on the irregular support. The lifting mechanism gradually lifts the stacked L-shaped paper sheets on the L-shaped moving plate, so that the L-shaped paper sheets can be continuously conveyed to the irregular support.

[0021] Step 2: The photovoltaic panel is conveyed to the blocking device position by the belt conveyor. The second proximity sensor of the blocking device detects the photovoltaic panel and transmits an electrical signal to the external controller. The external controller controls the output end of the second dual-axis cylinder to move upward, which drives the blocking rod to move upward, blocking the photovoltaic panel.

[0022] Step 3: The L-shaped paper is fed by the paper feeding device to the irregular support of the first folding mechanism of the corner protection folding device. The multiple lifting mechanism raises it a certain distance, lifting the L-shaped paper on the irregular support to the lower surface of the photovoltaic panel. The paper limiting plate is used to limit the L-shaped paper and prevent it from deviating. The output shaft of the first stepper motor rotates, which drives the flipping support on the left side of the irregular support to rotate. The rotation of the flipping support on the left side of the irregular support drives the first bevel gear to rotate. The rotation of the first bevel gear drives the second bevel gear to rotate. The rotation of the second bevel gear drives the flipping support on the rear side of the irregular support to rotate, folding the two ends of the L-shaped paper so that it is close to the side wall of the photovoltaic panel.

[0023] Step 4: The output shaft of the second stepper motor of the secondary folding mechanism on the left side of the primary folding mechanism rotates, causing the rotating plate to rotate, and the left end of the L-shaped paper to be folded once is folded a second time. The output shaft of the second stepper motor of the secondary folding mechanism on the rear side of the primary folding mechanism rotates, causing the rotating plate to rotate, and the rear end of the L-shaped paper to be folded once is folded a second time. The two ends of the L-shaped paper overlap vertically, and the rear end of the folded L-shaped paper is located on the upper side of the left end of the folded L-shaped paper.

[0024] Step 5: The multiple lifting mechanism raises the photovoltaic panel a certain distance again, lifting it up. The photovoltaic panel moves upward, and the pressing plate of the pressing mechanism presses the L-shaped paper piece, which has been folded twice, into the side groove of the photovoltaic panel. The output end of the first dual-axis cylinder moves, driving the insertion plate to move towards the L-shaped paper piece. The rear end of the folded L-shaped paper piece is located on the upper side of the left end of the folded L-shaped paper piece. The insertion plate moves towards the rear end of the folded L-shaped paper piece and presses it into the side groove of the photovoltaic panel. The corner protector installation is complete.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] This invention utilizes a corner-protecting folding device to fold both ends of an L-shaped paper sheet into place against the sidewall of a photovoltaic panel. The second stepper motor output shaft of the secondary folding mechanism on the left side of the primary folding mechanism rotates a rotating plate, causing a secondary fold on the left end of the L-shaped paper sheet. The second stepper motor output shaft of the secondary folding mechanism on the rear side of the primary folding mechanism rotates the rotating plate, causing a secondary fold on the rear end of the L-shaped paper sheet. The two ends of the L-shaped paper sheet overlap vertically, and the rear end of the folded L-shaped paper sheet is positioned above the left end of the folded L-shaped paper sheet. This facilitates a secondary folding of the L-shaped paper sheet, further adhering it to the photovoltaic panel. It also allows for automatic multiple folding of the L-shaped paper sheet, ensuring it adheres tightly to the photovoltaic panel.

[0027] The multiple lifting mechanism raises the photovoltaic panel a certain distance, lifting it up. As the panel moves upward, the pressing plate of the pressing mechanism presses the L-shaped paper, which has been folded twice, into the side groove of the photovoltaic panel. The output end of the first dual-axis cylinder moves, causing the insertion plate to move towards the L-shaped paper. The rear end of the folded L-shaped paper is located above the left end of the folded L-shaped paper. The insertion plate moves towards the rear end of the folded L-shaped paper, pressing it into the side groove of the photovoltaic panel, which helps to further fix the L-shaped paper to the photovoltaic panel. At the same time, side supports are provided at all four corners of the photovoltaic panel. A corner protection folding device for folding the photovoltaic panel corners is installed on the right side of the side supports, which helps to simultaneously wrap the four corners of the photovoltaic panel, resulting in high corner wrapping efficiency.

[0028] The downward movement of the output end of the second slide cylinder drives the suction cup downward, which in turn picks up the L-shaped paper. The upward movement of the output end of the second slide cylinder drives the suction cup upward, while the rightward movement of the output end of the first slide cylinder drives the second slide cylinder and the suction cup to move to the right. The rightward movement of the second slide cylinder and the suction cup moves the L-shaped paper on the suction cup to the irregular support of the first folding mechanism. The downward movement of the output end of the second slide cylinder drives the suction cup downward, which places the L-shaped paper on the irregular support, facilitating the continuous feeding of the L-shaped paper.

A paper limiting plate 10 is fixedly installed on the right side of the irregularly shaped bracket 61. The right side of the paper limiting plate 10 is provided with a protrusion to limit the L-shaped paper 9 and prevent it from shifting.

[0052] L-shaped paper sheet 9 is fed by paper sheet feeding device 7 to the irregular bracket 61 of the first folding mechanism of corner protection folding device 6. The multiple lifting mechanism raises it a certain distance, lifting the L-shaped paper sheet 9 on the irregular bracket 61 to the lower surface of photovoltaic panel 4. Paper sheet limiting plate 10 is used to limit the L-shaped paper sheet 9 and prevent it from deviating. The output shaft of the first stepper motor 63 rotates, driving the flipping bracket 62 on the left side of the irregular bracket 61 to rotate. The rotation of the flipping bracket 62 on the left side of the irregular bracket 61 drives the first bevel gear 64 to rotate. The rotation of the first bevel gear 64 drives the second bevel gear 65 to rotate. The rotation of the second bevel gear 65 drives the flipping bracket 62 on the rear side of the irregular bracket 61 to rotate, folding both ends of the L-shaped paper sheet 9 so that it is close to the side wall of photovoltaic panel 4, which is conducive to the first folding of L-shaped paper sheet 9.

[0055] Example 2

[0056] like Figures 1-12 As shown, in a preferred embodiment of the present invention, the paper feeding device 7 includes: a lifting mechanism 71, an L-shaped moving plate 72, vertical baffles 73, and a first proximity sensor 74. The lifting mechanism 71 is installed on the left side of the side support 5. The L-shaped moving plate 72 is fixedly installed on the output end of the lifting mechanism 71. Multiple vertical baffles 73 are fixedly installed on the left side of the side support 5. The L-shaped moving plate 72 is arranged between the vertical baffles 73.

The lifting mechanism 71 can be configured as a servo lifting mechanism.

[0057] The L-shaped paper sheet 9 is placed on the L-shaped moving plate 72 of the paper sheet feeding device 7. The first proximity sensor 74 on the side wall of the vertical baffle 73 detects whether the highest point of the stacked L-shaped paper sheet 9 on the upper side of the L-shaped moving plate 72 is in the preset position. The vertical baffle 73 is used to restrict the L-shaped paper sheet 9 so that it will not fall off the L-shaped moving plate 72. The lifting mechanism 71 gradually lifts the stacked L-shaped paper sheet 9 on the L-shaped moving plate 72, which is conducive to the paper sheet feeding device 7 to perform normal material picking.

[0058] The corner protector pressing device 8 includes a conveying mechanism and a pressing mechanism. The conveying mechanism is installed on the left side of the side bracket 5, and the pressing mechanism is installed on the right side of the conveying mechanism.

[0059] The conveying mechanism transports the L-shaped paper sheet 9 to the irregular bracket 61 of the primary folding mechanism of the corner protection folding device 6. The L-shaped paper sheet 9 is folded by the corner protection folding device 6, and then pressed into the photovoltaic panel 4 by the pressing mechanism to prevent it from falling off.

[0060] The conveying mechanism includes: a first slide cylinder 81, a second slide cylinder 82, and a suction cup 83. The first slide cylinder 81 is fixedly installed on the rear side of the side bracket 5 by a bracket. The second slide cylinder 82 is fixedly installed on the output end of the first slide cylinder 81. The suction cup 83 is fixedly installed on the output end of the second slide cylinder 82.

[0061] The output end of the second slide cylinder 82 moves downward, causing the suction cup 83 to move downward. The suction cup 83 moves downward and picks up the L-shaped paper piece 9. The output end of the second slide cylinder 82 moves upward, causing the suction cup 83 to move upward. The output end of the first slide cylinder 81 moves to the right, causing the second slide cylinder 82 and the suction cup 83 to move to the right. The second slide cylinder 82 and the suction cup 83 move to the right, causing the L-shaped paper piece 9 on the suction cup 83 to move onto the irregular support 61 of the first folding mechanism. The output end of the second slide cylinder 82 moves downward, causing the suction cup 83 to move downward. The suction cup 83 moves downward and places the L-shaped paper piece 9 on the irregular support 61, which is beneficial for the continuous conveying of the L-shaped paper piece 9.

[0062] The pressing mechanism includes: an extension bracket 84, a pressure plate 85, a first dual-axis cylinder 86, and an insertion plate 87. The extension bracket 84 is fixedly mounted on the bracket of the first slide cylinder 81. The pressure plate 85 is fixedly mounted on the lower side of the extension bracket 84.

[0063] The multiple lifting mechanism rises again a distance, lifting the photovoltaic panel 4. The photovoltaic panel 4 moves upward, and the pressing plate 85 of the pressing mechanism presses the L-shaped paper piece 9, which has been folded twice, into the side groove of the photovoltaic panel 4. The output end of the first dual-axis cylinder 86 moves, driving the insertion plate 87 to move towards the L-shaped paper piece 9. The rear end of the folded L-shaped paper piece 9 is located on the upper side of the left end of the folded L-shaped paper piece 9. The insertion plate 87 moves towards the rear end of the folded L-shaped paper piece 9 and presses it into the side groove of the photovoltaic panel 4, which helps to further fix the L-shaped paper piece 9 on the photovoltaic panel 4.

[0064] The material blocking device 2 includes: a second dual-axis cylinder 21, a stop bar 22, and a second proximity sensor 23. The second dual-axis cylinder 21 is fixedly installed on the lower side of the frame 1. Multiple stop bars 22 are fixedly installed on the output end of the second dual-axis cylinder 21 through brackets. The second proximity sensor 23 is fixedly installed on the upper side of the frame 1 to detect whether the photovoltaic panel 4 is close.

[0065] The second proximity sensor 23 is used to detect whether the photovoltaic panel 4 is close to the blocking device 2. When the photovoltaic panel 4 is close, the output end of the second dual-axis cylinder 21 of the blocking device 2 moves upward, driving the blocking rod 22 to move upward, blocking the photovoltaic panel 4, which is beneficial for the subsequent installation of the corner protector.

[0066] Example 3

[0067] like Figures 1-12 As shown in the figure, as a preferred embodiment of the present invention, a method for an automatic photovoltaic module foot wrapping machine, the working process of this embodiment is as follows:

[0068] Step 1: Place the L-shaped paper sheet 9 on the L-shaped moving plate 72 of the paper sheet feeding device 7. The output end of the second slide cylinder 82 moves downward, driving the suction cup 83 to move downward. The suction cup 83 moves downward to pick up the L-shaped paper sheet 9. The output end of the second slide cylinder 82 moves upward, driving the suction cup 83 to move upward. The output end of the first slide cylinder 81 moves to the right, driving the second slide cylinder 82 and the suction cup 83 to move to the right. The second slide cylinder 82 and the suction cup 83 move to the right, driving the L-shaped paper sheet 9 on the suction cup 83 to move to the irregular support 61 of the first folding mechanism. The output end of the second slide cylinder 82 moves downward, driving the suction cup 83 to move downward. The suction cup 83 moves downward, placing the L-shaped paper sheet 9 on the irregular support 61. The lifting mechanism 71 gradually lifts the stacked L-shaped paper sheets 9 on the L-shaped moving plate 72, so that the L-shaped paper sheet 9 can be continuously conveyed to the irregular support 61.

[0069] Step 2: The photovoltaic panel 4 is conveyed to the position of the blocking device 2 by the belt conveyor 3. The second proximity sensor 23 of the blocking device 2 detects the photovoltaic panel 4 and transmits the electrical signal to the external controller. The external controller controls the output end of the second dual-axis cylinder 21 to move upward, which drives the blocking rod 22 to move upward, thus blocking the photovoltaic panel 4.

[0070] Step 3: The L-shaped paper sheet 9 is fed by the paper sheet feeding device 7 to the irregular bracket 61 of the first folding mechanism of the corner protection folding device 6. The multiple lifting mechanism lifts it a certain distance, lifting the L-shaped paper sheet 9 on the irregular bracket 61 to the lower surface of the photovoltaic panel 4. The paper sheet limiting plate 10 is used to limit the L-shaped paper sheet 9 and prevent it from deviating.

[0071] Step 4: The output shaft of the second stepper motor 67 of the secondary folding mechanism on the left side of the primary folding mechanism rotates, causing the rotating plate 66 to rotate, and the left end of the L-shaped paper 9 to be folded once is folded a second time. The output shaft of the second stepper motor 67 of the secondary folding mechanism on the rear side of the primary folding mechanism rotates, causing the rotating plate 66 to rotate, and the rear end of the L-shaped paper 9 to be folded once is folded a second time. The two ends of the L-shaped paper 9 overlap vertically, and the rear end of the folded L-shaped paper 9 is located on the upper side of the left end of the folded L-shaped paper 9.

[0072] Step 5: The multiple lifting mechanism raises the photovoltaic panel 4 a certain distance again, lifting it up. The photovoltaic panel 4 moves upward, and the pressing plate 85 of the pressing mechanism presses the L-shaped paper piece 9, which has been folded twice, into the side groove of the photovoltaic panel 4. The output end of the first dual-axis cylinder 86 moves, driving the insertion plate 87 to move towards the L-shaped paper piece 9. The rear end of the folded L-shaped paper piece 9 is located on the upper side of the left end of the folded L-shaped paper piece 9. The insertion plate 87 moves towards the rear end of the folded L-shaped paper piece 9 and presses it into the side groove of the photovoltaic panel 4. The corner protector installation is completed.
