Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic components, in particular to an automatic foot wrapping machine for photovoltaic components and a method thereof. Background Art

[0002] A photovoltaic panel is a device that uses the photovoltaic effect to convert light energy directly into electrical energy. It is usually composed of multiple solar cells connected in series or in parallel. During the production and transportation of photovoltaic panels, in order to protect the corners from collision and wear, corner guards are usually installed at the corners. The corner guards are usually paper corner guards, usually kraft paper, tube paper, etc. Paper corner guards are relatively light in weight, easy to carry and operate, low in cost, relatively cheap in raw materials, and relatively simple in production process, making their cost more economical. At the same time, paper is a recyclable material and meets environmental protection requirements.

[0003] Chinese patent CN219193146U proposes a corner wrapping device suitable for solar photovoltaic modules, including a base plate, a control panel installed on the right side of the top of the base plate, a movable seat installed in the middle of the top of the base plate, a worm gear installed on the top of the movable seat, a driving mechanism installed on the left side of the top of the base plate, and the left side of the worm gear is connected to the driving mechanism. Through the continuous rotation of the first motor, the corner wrapping structure can be controlled to move up and down, so that the corner wrapping structure can be accurately moved to the height of the corner of the photovoltaic module. By controlling the second motor to drive the worm to rotate, the worm and the worm gear are meshed and driven, and the support frame is driven to rotate, the angle of the corner wrapping structure can be adjusted, so that the corner wrapping structure can be accurately fitted on the outside of the photovoltaic module, and the corner wrapping module can be accurately positioned, which is convenient for protecting the corners of the photovoltaic module.

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

[0005] 1. This patent controls the up and down movement of the corner structure by the continuous rotation of the first motor, so that the corner structure can be accurately moved to the height of the corner of the photovoltaic module. The second motor is controlled to drive the worm to rotate, so that the worm and the worm wheel are engaged and driven to rotate, and the support frame is driven to rotate to adjust the angle of the corner structure, so that the corner structure can be accurately mounted on the outside of the photovoltaic module, and the accurate positioning of the corner module can be achieved. Therefore, it can only install one corner guard at a time, and cannot install corner guards on the four corners of the photovoltaic module at the same time, and the corner wrapping efficiency is low.

[0006] 2. This patent cannot automatically bend an L-shaped paper piece to form a paper corner protector, and can only use the finished corner protector for installation, and cannot realize the automatic loading operation of the corner protector, so the production efficiency is relatively low.

[0019] In order to better achieve the purpose of the present invention, the present invention also provides a method for automatically wrapping a photovoltaic module foot protection machine, comprising the following steps:

[0020] Step 1: Place the L-shaped paper piece on the L-shaped moving plate of the paper feeding device, the output end of the second slide cylinder moves downward to drive the suction cup to move downward, the suction cup moves downward to suck up the L-shaped paper piece, the output end of the second slide cylinder moves upward to drive the suction cup to move upward, the output end of the first slide cylinder moves to the right to drive 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 to drive the L-shaped paper piece on the suction cup to move to the special-shaped bracket of the primary folding mechanism, the output end of the second slide cylinder moves downward to drive the suction cup to move downward, the suction cup moves downward to place the L-shaped paper piece on the special-shaped bracket, and the lifting mechanism gradually lifts the stacked L-shaped paper pieces on the L-shaped moving plate so that the L-shaped paper pieces can be continuously transported to the special-shaped bracket;

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

[0022] Step 3: The L-shaped paper piece is conveyed to the special-shaped bracket of the primary folding mechanism of the corner folding device through the paper feeding device, and the multiple lifting mechanisms are raised for a certain distance to lift the L-shaped paper piece on the special-shaped bracket to the lower surface of the photovoltaic panel. The paper limit plate is used to limit the L-shaped paper piece to prevent it from deflecting.

[0027] The multiple lifting mechanism rises a distance again to lift the photovoltaic panel, and the photovoltaic panel moves upward. The pressing plate of the pressing mechanism presses the L-shaped paper piece that has been folded twice into the side groove of the photovoltaic panel. The output end of the first double-axis cylinder moves to drive the insertion plate to move toward the direction of 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 toward the rear end of the folded L-shaped paper piece and presses it into the side groove of the photovoltaic panel, which is conducive to further fixing the L-shaped paper piece on the photovoltaic panel. At the same time, side brackets are provided at the four corners of the photovoltaic panel, and a corner folding device for folding and forming the corner guards of the photovoltaic panel is installed on the right side of the side bracket, which is conducive to synchronous wrapping of the four corners of the photovoltaic panel, and the corner wrapping efficiency is high.

[0028] The output end of the second slide cylinder moves downward, driving the suction cup downward, and the suction cup moves downward to suck up the L-shaped paper piece. The output end of the second slide cylinder moves upward, driving the suction cup 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 piece on the suction cup to the special-shaped bracket of the primary folding mechanism.
