Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment technology, and in particular relates to a photovoltaic module corner wrapping machine. Background Technology

[0002] See Figure 1 To prevent the four corners of the aluminum alloy frame of the photovoltaic module 10 from scratching the glass or backsheet surface during stacking, and to prevent damage to the four corners during handling, corner protectors, commonly known as corner protectors, are usually wrapped around the four corners of the aluminum alloy frame of the photovoltaic module 10. These corner protectors are divided into corner protector type 1 (21) and corner protector type 2 (22). See also Figures 2-5 Corner protector 21 is folded from paper card 21A, see below. Figures 6-7 Corner protector 22 is folded from paper card 22A. If the paper card is not double-sided, paper card 1 21A and paper card 22A are actually the same, the only difference being that the outward-facing sides are reversed when folded. When wrapping the corners, first place two paper cards 1 21A and two paper cards 22A at the four corners and place them under the photovoltaic module 10 to be wrapped. Align the right angle of the triangular corner protector base 21A1 with the right angles of the four corners of the aluminum alloy frame of the photovoltaic module 10 with the glass plate facing down. Then fold two paper cards 1 21A and two paper cards 22A. Taking corner protector 21 as an example, first bend vertically, see... Figure 3 First, bend the side 21A2 of the lower corner protector along the fold line 21A6 relative to the bottom surface 21A1 of the corner protector at a 90° angle to the left or right side of the aluminum alloy frame of the photovoltaic module 10. Then, bend the side 21A4 of the upper corner protector along the fold line 21A8 relative to the bottom surface 21A1 of the corner protector at a 90° angle to the front or rear side of the aluminum alloy frame of the photovoltaic module 10, and make one side of the upper corner protector side 21A4 and one side of the lower corner protector side 21A2 join to cover the four sharp corners of the aluminum alloy frame of the photovoltaic module 10, thus obtaining the vertical corner protector 21B; then fold horizontally, see [reference]. Figure 4 First, bend the lower corner protector cover 21A3 at a 90° angle along the fold line 21A7 towards the bottom surface 21A1 of the corner protector and attach it to the top of the aluminum alloy frame of the photovoltaic module 10. Then, bend the upper corner protector cover 21A5 at a 90° angle along the fold line 21A9 towards the bottom surface 21A1 of the corner protector and cover the lower corner protector cover 21A3, resulting in a flat-folded corner protector 21C. Finally, fold the edges together, see [reference needed]. Figure 5The second locking edge surface 21AC of the corner protector is folded downwards and inwards towards the aluminum alloy frame along the fold line 21AD of the second locking edge surface. Simultaneously, the first locking edge surface 21AA of the corner protector is folded downwards and inwards towards the aluminum alloy frame along the fold line 21AB of the first locking edge surface. This ensures that the bottom side of the second locking edge surface 21AC is pressed firmly against the back panel of the photovoltaic module 10. Then, the cross-edge portion of the fold line 21AD of the second locking edge surface is pushed forcefully, causing the fold line 21AD to be recessed and pressed against the inner side of the aluminum alloy frame. The first locking edge surface 21AA and the second locking edge surface 21AC of the corner protector are fixed inside the aluminum alloy frame, completing the locking process and obtaining corner protector 21. A corner protector 21AC1 is provided on the bottom side of the second locking edge surface 21AC for applying force during locking and for inserting a finger to pry out the second locking edge surface 21AC when removing corner protector 21.

12. The photovoltaic module corner wrapping machine according to claim 11, wherein the corner protection top cover assembly (700A6) includes a corner protection top cover bracket (700A61), a corner protection top cover lifting drive (700A62), a corner protection top cover translation drive (700A63), and a corner protection top cover folding palm (700A64); The folding corner cover bracket (700A61) is fixed in front of the platform (700A2) and to the left of the front and rear positioning assembly (700A3). The folding corner cover lifting drive (700A62) is vertically fixed upward on the folding corner cover bracket (700A61). The folding corner cover translation drive (700A63) is horizontally fixed backward on the output end of the folding corner cover lifting drive (700A62). The folding corner cover folding palm (700A64) faces the platform (700A2) and is fixed on the output end of the folding corner cover translation drive (700A63). The lifting drive (700A62) for lifting the corner protector top cover is used to drive the corner protector top cover translation drive (700A63) to lift the corner protector top cover folding palm (700A64) of the paper card one (21A) to the front or rear side of the aluminum alloy frame of the photovoltaic module (10) after the corner protector bottom cover assembly (700A5) folds the corner protector bottom cover (21A3) to the front or rear side of the aluminum alloy frame of the photovoltaic module (10). The corner protector top cover translation drive (700A63) is used to drive the corner protector top cover folding palm (700A64) to extend backward and horizontally fold the corner protector top cover (21A5) of the paper card one (21A) to the top of the aluminum alloy frame of the photovoltaic module (10) and cover part of the corner protector bottom cover (21A3).

13. The photovoltaic module corner wrapping machine according to claim 5, wherein the paper card left corner wrapping and locking mechanism (900A) includes a paper card left corner wrapping and locking robot base (900A1), a paper card left corner wrapping and locking robot (900A2), a paper card left corner wrapping and locking robotic arm (900A3), and a paper card left corner wrapping and locking hand (900A4); The paper card left corner sealing robot base (900A1) is fixed to the left center of the paper card left transverse sliding plate (500A7). The paper card left corner sealing robot (900A2) is fixed to the paper card left corner sealing robot base (900A1). The paper card left corner sealing robotic arm (900A3) is positioned below the movable end of the paper card left corner sealing robot (900A2). The paper card left corner sealing hand (900A4) is fixed below the paper card left corner sealing robotic arm (900A3). The paper card left corner sealing... The locking hand (900A4) is provided with the palm tip (900A41) of the locking hand on the left corner of the paper card; the locking robot (900A2) is used to drive the locking hand (900A4) to lift, rotate and translate, so that the palm tip (900A41) of the locking hand folds the locking edges of the left paper card one (21A) and the paper card two (22A) into the aluminum frame on the left front and left rear sides of the photovoltaic module (10) to obtain corner protector one (21) and corner protector two (22); The right corner locking mechanism (900B) and the left corner locking mechanism (900A) of the paper card have the same structure and are mirror images of each other.
