Description

Technical Field

[0001] This invention relates to the field of solar panel film application equipment technology, specifically a solar panel film application equipment. Background Technology

[0002] During production, transportation, and installation, solar panels are susceptible to scratches, contamination, or corrosion. To protect them, a protective film is typically applied to their surface. Traditional manual film application methods are inefficient, labor-intensive, and produce inconsistent application quality (such as bubbles, wrinkles, and misalignment), making them unsuitable for large-scale automated production.

[0003] While existing automated film application equipment has improved efficiency to some extent, it still has many limitations: for example, it cannot flexibly adapt to solar panels of different sizes and specifications; burrs may be generated at the edges after the film material is cut, which affects the quality of direct application; it is difficult to effectively avoid the generation of air bubbles during the application process; and the equipment lacks flexibility and is difficult to change.

[0004] Therefore, there is an urgent need for a solar panel film application device and method that is highly automated, has good adhesion quality, and can flexibly adapt to different product specifications. Summary of the Invention

A hand limiting slide is provided on the side wall of the hand assembly frame. The movable suction cup group is slidably embedded in the hand limiting slide. The hand drive motor is driven by the movable suction cup group and is used to drive the movable suction cup group to slide along the hand limiting slide and adjust the distance between the movable suction cup group and the fixed suction cup group. The hand cylinder is fixed to one side of the hand assembly frame, and its output end is fixedly connected to the fixed suction cup group and is used to drive the fixed suction cup group to rise and fall. The lower end surfaces of the fixed suction cup group and the movable suction cup group are on the same plane and can both generate negative pressure for flat adsorption and unfolding of the film material.

[0012] Preferably, the robotic arm material handling unit and the film application and installation frame are arranged side by side, and the solar panel conveying unit is located below the robotic arm material handling unit.

[0015] Preferably, the solar panel film application device further includes a film tail bonding processing mechanism disposed at the tail of the film application mounting frame. When the film application unit presses the film from the head of the film onto the plate to near the tail of the film, and the tail of the film is about to detach from the film application hand, at least a portion of the film tail bonding processing mechanism is located between the tail of the film and the film application mounting frame, so that the film tail bonding processing mechanism can receive the tail of the film.

[0016] A method for applying a film to a solar panel includes the following steps:

[0017] S1, Solar Panel Loading: The solar panels are mounted on the solar panel conveying unit, which pushes them onto the film-applying mounting frame.

[0018] S2, Film feeding: Start the unwinding unit to pull the film out to directly above the film application and installation frame, so that the film is above the solar panel fabric.

[0019] S3, Film Material Adsorption: The robotic arm material handling unit controls the coating palm to be parallel to the top of the film material, and then activates the fixed suction cup group and the movable suction cup group on the coating palm to adsorb and fix the film material on both sides.

[0020] S4, Film material cutting: Start the unwinding and cutting assembly to cut the film material.

[0022] S6, Membrane trimming: The robotic arm picking unit delivers the membrane material to the membrane trimming unit and delivers the four corners of the membrane material to the trimming limit baffle. After the trimming limit baffle presses the membrane material, the trimming cutting tool is activated to cut and trim the membrane material.

[0023] S7, Film Application: The robotic arm picking unit delivers the film to the film application mounting frame. The film application hand is tilted so that the film on one side of the fixed suction cup group on the film application hand first contacts one side of the upper surface of the solar panel. The fixed suction cup group releases pressure to release the film. The robotic arm picking unit is activated to push the film application hand to move horizontally on the upper surface of the solar panel. At the same time, the hand drive motor drives the movable suction cup group to move synchronously toward the fixed suction cup group. As the robotic arm picking unit moves horizontally, the film application unit moves synchronously to press the film onto the solar panel. After the film application is completed, the movable suction cup group releases pressure to release the film, and the robotic arm picking unit resets.

[0024] S8, Solar Panel Unloading: The solar panel conveying unit will complete the unloading of the film-coated solar panels;

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] Fully Automated Production: Integrating feeding, cutting, peeling, trimming, attaching, and unloading into one unit, it greatly improves production efficiency and consistency while reducing labor costs and intensity. High Attachment Quality: The unique "trimming before attaching" process avoids damage that may occur during trimming on the solar panel; the biomimetic "tilted attachment, synchronous rolling" attachment method effectively eliminates air bubbles and wrinkles. High Flexibility and Agility. Rational Layout and Efficient Operation: The layout with the robotic arm at the center and functional units arranged around it optimizes material flow paths and shortens cycle time.

[0046] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0047] like Figures 1 to 12 The solar panel film application device shown includes an unwinding unit 1, a robotic arm material handling unit 2, a solar panel conveying unit 3, a film trimming unit 4, a film application and installation frame 5, and a peeling device 7.

[0048] The robotic arm material handling unit 2 is centrally located, serving as the core of the system's motion. The film trimming unit 4, the film application and mounting frame 5, and the hand storage unit 6 are arranged around the robotic arm material handling unit 2 to ensure efficient access to each workstation. The solar panel conveying unit 3 is positioned corresponding to the film application and mounting frame 5, used to transport the solar panels to be applied to the frame 5 and precisely position them.

[0049] A film-applying unit 8 is slidably mounted on the upper surface of the film-applying mounting frame 5 for pressing the film material during application. A peeling device 7 is fixedly mounted on the film-applying mounting frame 5 for peeling off the adhesive backing of the film material. An unwinding unit 1 is located on the side of the film-applying mounting frame 5 for unwinding the film material in its wound state and cutting it into an unfolded film material equivalent to the length of the solar panel.

[0050] The unwinding unit 1 includes a winding roller assembly 11, an unwinding and cutting assembly 12, and a film stretching assembly 13. The winding roller assembly 11 is used to install and store the film material in its wound state, and can limit the bending of the corners when the film material is unwound, ensuring that the film material is flat. The film stretching assembly 13 is used to assist in pulling the film material from the winding roller assembly 11 to a predetermined position. The unwinding and cutting assembly 12 is used to cut the film material when it reaches the required length.

[0051] The solar panel conveying unit 3 includes a conveying bracket, a conveying roller assembly, and a panel positioning mechanism. The conveying roller assembly is used to convey the solar panels. The panel positioning mechanism includes two opposing positioning cylinders and a positioning push plate, used to clamp and position the solar panels arriving at the film-coating station.

[0052] The film trimming unit 4 includes a trimming mounting frame 41, a trimming moving track 42, a trimming cutting blade 43, a trimming limiting baffle 44, a trimming limiting pressure plate 45, a trimming pressure plate motor 46, and a trimming waste conveyor belt 47. The trimming cutting blade 43 can move along the track. After the trimming limiting pressure plate 45 presses the film material, it precisely trims the edges of the film material. Waste is automatically collected by the waste conveyor belt.

[0053] The coating unit 8 includes a coating roller 81, a coating crossbeam 82, a coating slide rail 83, a coating motor 84, and a coating cylinder 85. The coating motor 84 drives the coating crossbeam 82 to move along the slide rail, and the coating cylinder 85 drives the coating roller 81 to rise and fall, so as to press the film material onto the surface of the solar panel.

[0054] The solar panel film application device also includes a film-applying hand 9, which comprises a robotic arm docking part 91, a hand assembly frame 92, a fixed suction cup assembly 93, a movable suction cup assembly 94, a hand drive motor 95, and a hand cylinder 96. The robotic arm docking part 91 is used to connect with a robotic arm. The movable suction cup assembly 94 is slidably mounted on the hand assembly frame 92 and is driven by the hand drive motor 95 to adjust the distance between it and the fixed suction cup assembly 93, thereby accommodating film materials of different widths. The hand cylinder 96 is used to drive the suction cup assembly to move up and down. Both the fixed suction cup assembly 93 and the movable suction cup assembly 94 can generate negative pressure to smoothly adsorb the film material.

[0055] The solar panel film application device also includes a hand storage unit 6, which is also arranged around the perimeter of the robotic arm material handling unit 2. The hand storage unit 6 stores several film-coated hands 9 of different sizes. The control end of the robotic arm material handling unit 2 is detachably equipped with the film-coated hands 9 and can reciprocate between the unwinding unit 1, the film trimming unit 4, the film application mounting frame 5, and the hand storage unit 6 to perform operations such as material handling, transfer, application, and hand replacement.

[0056] The palm storage unit 6, the robotic arm material handling unit 2, and the film application and installation frame 5 are arranged side by side, with the solar panel conveying unit 3 located below them. The layout is compact and the space utilization rate is high.

[0057] The palm storage unit 6 includes a palm assembly base 61 and a palm assembly frame 62. The assembly frame is provided with an inclined palm main support frame 621, and the support surface faces the robotic arm, which facilitates the robotic arm to perform pick-up and put-down operations.

[0058] The solar panel film application device also includes a film tail bonding processing mechanism 10, which is located at the tail of the film application mounting frame 5. When the film application unit 8 presses the film from the head of the film onto the solar panel B to near the tail of the film, and the tail of the film is about to detach from the film application hand 9, at least part of the film tail bonding processing mechanism 10 is located between the tail of the film and the solar panel B on the film application mounting frame 5, so that the film tail bonding processing mechanism 10 can receive the tail of the film.

[0059] The film material tail bonding processing mechanism 100 includes a receiving assembly 101 located at the tail of the film bonding mounting frame 5. During the process of pressing film material A onto solar panel B, film material A is pressed onto solar panel B gradually from its head to its tail. Based on this, at the beginning of the process, the head of film material A is first detached from the coating hand 9, while the tail of film material A is still in the holding state of the coating hand 9; when film material A is pressed onto solar panel B and is close to the tail of film material A and the tail of film material A is about to detach from the coating unit 8, at least a portion of the receiving assembly 101 can be positioned between the tail of film material A and solar panel B, so that the receiving assembly 101 can receive the tail of film material A and prevent the tail of film material A from contacting solar panel B.

[0060] As the film material A is pressed from its initial position onto the solar panel B to its final position near the solar panel B, and as the final position of film material A is about to detach from the coating hand 9, at least a portion of the receiving component 10 is positioned between the final position of film material A and the solar panel B, allowing the receiving component 10 to receive the final position of film material A. This effectively prevents air bubbles from forming between the final position of film material A and the solar panel B due to the final position of film material A falling onto and contacting the solar panel B, thus significantly improving the bonding quality between film material A and the solar panel B and greatly increasing product yield.

[0061] In some embodiments, the film material tail bonding processing mechanism 10 further includes a guide rail, a bracket, and a drive component. The guide rail is disposed on the film bonding mounting frame 5, and the bracket is movably connected to the guide rail. Furthermore, the guide rail 110 is relatively short to limit the movement of the bracket within a short distance at the tail of the film bonding mounting frame 5. The drive component can be connected to the bracket to drive the bracket to move on the guide rail, i.e., it can move along the length of the film bonding mounting frame 5.

[0062] The driving component can be any power element that can drive the bracket to move on the guide rail, such as a motor or air pump.

[0063] The receiving assembly 100 can be mounted on a bracket so that the receiving assembly 10 can be suspended on the film application mounting frame 5. Even if there is a gap between the receiving assembly 10 and the solar panel B mounted on the film application mounting frame 5, when the film A is pressed close to the tail of the film A and the tail of the film A is separated from the film application hand 9, the tail of the film A will not come into contact with the solar panel B.

[0064] Understandably, when the film material A is pressed close to the tail of the film material A, the bracket can be moved along the length of the film mounting frame 5 towards the solar panel B, so that the receiving assembly 101 can be located between the tail of the film material A and the solar panel B. At this time, the tail of the film material A can be detached from the film covering hand 9 and fall onto the receiving assembly 101, so that the receiving assembly 101 can receive the tail of the film material A, effectively preventing the tail of the film material A from contacting the panel.

[0065] While continuing to press the tail of film material A, the support can be moved away from the solar panel B along the length of the film mounting frame 5, so as to cooperate with the pressing direction of film material A to gradually separate the tail of film material A from the receiving plate and gradually press the tail of film material A onto the solar panel B.

[0066] In some embodiments, the receiving assembly 101 may include a connecting rod 1011 and a receiving element. The connecting rod 1011 may be disposed on a bracket, and the receiving element may be connected to the connecting rod 1011.

[0067] In some embodiments, the receiving component may include a plurality of receiving portions 1012, each receiving portion 1012 being spaced apart along the length of the connecting rod 1011, so as to reduce the contact area of ​​the tail of the film material A on the receiving component, effectively reduce the dust that may be picked up by the tail of the film material A when it comes into contact with the receiving component, and improve the overall bonding quality of the film material A and the solar panel B.

[0068] In some embodiments, the film material tail bonding processing mechanism 10 further includes an air blowing assembly 102 disposed on a support, so that when the film material A is pressed close to its tail and its tail is detached from the covering palm 9, the tail of the film material A can be kept in a suspended state by blowing air on the tail of the film material A, so as to avoid the tail of the film material A from contacting the solar panel B.

[0069] Understandably, the working principle of the material receiving assembly 101 and the air blowing assembly 102 working together is roughly as follows:

[0070] First, when the membrane material A is pressed close to the tail of the membrane material A, the tail of the membrane material A can be blown by the air blowing component 102. At this time, the tail of the membrane material A can be separated from the covering palm 9. The airflow blown by the air blowing component 102 can keep the tail of the membrane material A in a suspended state.

[0071] Next, the support can be moved toward the solar panel B so that the receiving assembly 101 can be placed between the tail of the film material A and the solar panel B. At this time, the blowing assembly 102 can be controlled to stop blowing so that the tail of the film material A can overlap the receiving assembly 101.

[0072] Finally, as the coating unit 8 continues to press the tail of the film material A, the support can be moved away from the solar panel B to match the pressing direction of the film material A so that the tail of the film material A gradually separates from the coating hand 9, allowing the coating unit 8 to gradually press the tail of the film material A.

[0073] A method for applying a film to a solar panel using the above-described device includes the following steps:

[0074] Solar panel loading: Solar panel conveying unit 3 conveys the solar panels to film mounting frame 5 and positions them.

[0075] Adhesive-backed film pulling: Unwinding unit 1 pulls out and cuts the film material, suspending it directly above the film application mounting frame 5.

[0076] Film adsorption: The robotic arm material handling unit 2 controls the film-coating hand 9 to move above the film material and adsorbs the film material through the suction cup assembly.

[0077] Film backing adhesive removal: The peeling device 7 separates and peels off the backing adhesive of the film, exposing the adhesive layer.

[0078] Membrane trimming: The robotic arm transfers the membrane material to the membrane trimming unit 4, where the trimming unit presses and trims the four corners of the membrane material to remove burrs.

[0079] Film application: The robotic arm moves the trimmed film material above the solar panel. First, it tilts its hand so that one side of the film material contacts the solar panel, releasing pressure from the suction cups on that side. Then, the robotic arm moves horizontally, while the movable suction cup group 94 moves towards the fixed suction cup group 93. Simultaneously, the film coating unit 8 starts, pressing and attaching the film material to the surface of the solar panel. After application, all suction cups release pressure, and the robotic arm returns to its original position.

[0080] Solar panel unloading: Solar panel conveying unit 3 outputs the solar panels after the film has been applied.

[0081] Replacement of coated palm 9: When it is necessary to change the size of the battery panel, the robotic arm can put the current palm back into the palm storage unit 6 and grab a palm of another size.

[0082] The work process is as follows:

[0083] Material Feeding: The solar panel is conveyed to the film-applying mounting frame 5 by the solar panel conveying unit 3, and the positioning cylinder of the panel positioning mechanism pushes the positioning push plate to clamp and position it. Film Preparation: At the same time, the unwinding unit 1 starts working. The film material is pulled from the winding roller group 11 by the film pulling assembly 13 to a predetermined length equivalent to the length of the solar panel. Then, the unwinding and cutting assembly 12 operates to cut the film material. At this time, a section of the unfolded film material is suspended above the film-applying mounting frame 5. Film Removal and Adhesive Peeling: The robotic arm material-removing unit 2 moves the film-applying hand 9 to above the film material. The fixed suction cup group 93 and the movable suction cup group 94 on the film-applying hand 9 generate negative pressure to flatten and adsorb the film material. Subsequently, the peeling device 7 operates to peel off the protective adhesive at the bottom of the film material. Trimming: The robotic arm material-removing unit 2 transfers the adsorbed film material to the film material trimming unit 4. Trimming and limiting pressure plate 45, driven by a motor, presses the edge of the film material. Trimming and cutting blade 43 moves along trimming travel track 42 to precisely trim the edge of the film material. Waste material generated is collected and transported away by waste conveyor belt. Attachment: The robotic arm moves the trimmed film material onto the positioned solar panel. The robotic arm controls the coating hand 9 to tilt at an angle, so that the film material on one side of the fixed suction cup group 93 contacts the edge of the solar panel first. The fixed suction cup group 93 is depressurized, releasing the film material on that side. Subsequently, the robotic arm begins to move horizontally, pushing the film material to cover the surface of the solar panel. At the same time, the hand drive motor 95 drives the movable suction cup group 94 to slide towards the fixed suction cup group 93, keeping the film material taut and aligned. The coating unit 8 is activated, the coating motor 84 drives the coating crossbeam 82 to move, and the coating cylinder 85 presses down the coating roller 81, closely following the movement trajectory of the robotic arm to press the film material firmly onto the surface of the solar panel. This synchronous movement ensures perfect attachment of the film material without bubbles or wrinkles. Material loading and hand change: After the film is applied, the movable suction cup assembly 94 is depressurized, and the robotic arm carrying the film-coated hand 9 returns to its original position. The solar panel conveying unit 3 outputs the film-coated solar panel. If the next solar panel has a different specification, the robotic arm can go to the hand storage unit 6, put the current hand back, and grab a film-coated hand 9 of another size.

[0084] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the invention and should not be construed as limiting the scope of protection of the invention in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of the invention without inventive effort, and these embodiments will all fall within the scope of protection of the claims of the present invention.
