Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic cells, and in particular to a device and method for laying a cell packaging adhesive film. Background Art

[0002] At present, conventional photovoltaic cells on the market are composed of five layers: glass substrate, adhesive film, battery cell, adhesive film and backplane. The manufacturing process is usually to stack these five layers through a laying process during the production process, and then perform a lamination process. The adhesive film fixes the glass substrate, battery cell and backplane together.

[0003] When photovoltaic modules are stacked, a layer of EVA (ethylene-vinyl acetate copolymer) film is first covered on the back of the battery, and then a backplane is covered. Since the busbar on the battery needs to be led out, an opening needs to be cut on the EVA film so that the lead-out wire of the busbar can pass through the opening from the bottom of the EVA film to the top. With the advancement of technology, more and more mechanization is preferred. When automatic laying equipment is used, the equipment first places the glass plate on the workbench, then lays a layer of film on the workbench, lays the battery on the film, and then lays a layer of film on the battery, and then makes a hole in the film on the top of the battery, and the backplane is laid on the EVA film. Usually, two operators lift the two ends of the entire EVA film, drill holes at the corresponding positions, and then pass the lead-out wires through the opening position, and then cover the backplane. Such openings are prone to glue shortages; at the same time, if the above method is used to directly pull the EVA film back and forth on the surface of the battery array to make holes, it will cause abnormalities such as misalignment of the battery spacing, and even break the battery.

[0016] Step 2, controlling the adjustment components corresponding to the remaining suction cups that are not adsorbed to the film to adjust so that the suction cups are in contact with the film, and then controlling the solenoid valves corresponding to the remaining suction cups that are not adsorbed to the film to open, so that the remaining suction cups that are not adsorbed to the film adsorb the film;

[0019] Step 5, after cooling, two electromagnets in the same opening assembly are controlled to be energized and generate magnetic attraction, so that the scissors are brought close to each other and cut the rubber film protruding from the circular adsorption cavity under the action of the magnetic attraction, and then the electromagnets are controlled to be de-energized, and the scissors are reset under the action of the reset spring;

[0021] Technical effects and advantages of the present invention:

[0022] 1. The present invention can perform hole drilling without directly drilling holes in the adhesive film to remove part of the adhesive film through the mutual cooperation between the heating component and the hole opening component, thereby achieving hole drilling without reducing the adhesive film, thereby avoiding the situation of cutting off part of the adhesive film by direct punching as in the prior art, resulting in glue shortage.

[0023] 2.

[0046] The top and side walls of each accommodating cavity 708 are provided with a rotating groove 711 for rotating the scissors 7072. The scissors 7072 are hinged to the slider 7071 through a hinge. The hinge includes a first ear 7075 connected to the slider 7071 and a second ear 7076 connected to the scissors 7072.

[0047] A ferromagnetic layer 709 is provided at the bottom of the fixed shaft 705. Through the ferromagnetic layer 709, after the scissors 7072 slide out, the electromagnet on one of the scissors 7072 is energized, so that the scissors 7072 can overcome the reset torsion spring 7074 and engage with the ferromagnetic layer 709, so that when the cutting mechanism 4 fails, the scissors 7072 can be used to cut the film.

[0048] When in use, the glass plate with the battery sheet on the top is first transported to the laying position by the conveyor belt 203, and then the rotating motor 604 corresponding to the adjustment component 6 far away from the film row is controlled to rotate at a preset angle, that is, Figure 1 The rotary motors 604 in the rightmost row shown in the figure rotate at a preset angle, and the preset angle is to make the second electric telescopic rods 603 parallel to the length direction of the working box 1 and located on the left side of the central axis of the respective corresponding rotary motors 604. Since the second electric telescopic rods 603 in the row far away from the film are parallel to the length direction of the working box 1 and located on the left side of the central axis of the rotary motors 604, the second electric telescopic rods 603 can be extended toward the feeding roller 304 in the left side of the working box 1, and then the second electric telescopic rods 603 are controlled to extend, and at the same time, the first electric telescopic rods 602 corresponding to the remaining adjustment components 6 are controlled to retract upward to make way for the extension of the second electric telescopic rods 603 corresponding to the adjustment components 6 in the row far away from the film, that is, Figure 1 The first electric telescopic rods 602 corresponding to the remaining two rows of adjustment components 6 are retracted upward, so that the height of the suction cups corresponding to the remaining two rows of adjustment components 6 is higher than the height of the second electric telescopic rods 603 corresponding to the adjustment components 6 in the row away from the film, thereby giving way to the second electric telescopic rods 603 corresponding to the adjustment components 6 in the row away from the film to avoid the following Figure 1The remaining two rows of adjustment components 6 shown in the figure block the extension of the second electric telescopic rod 603 corresponding to the adjustment components 6 in the row away from the film; then the solenoid valve 704 in the suction cup 7 corresponding to the adjustment components 6 in the row away from the film is controlled to open, so as to absorb the film on the feeding roller 304, and then the driving motor for driving the feeding roller 304 to rotate is controlled to start, and then the second electric telescopic rod 603 corresponding to the adjustment components 6 in the row away from the film is controlled to retract, and the contraction of the second electric telescopic rod 603 drives the film to move to the side away from the feeding roller 304, and when the film is pulled to the same length as the photovoltaic cell to be laid, the second electric telescopic rod 603 is controlled to stop retracting, and then the control The first electric telescopic rods 602 corresponding to the other suction cups 7 that are not adsorbed to the film are controlled to extend to make the suction cups 7 contact the film, and then the solenoid valves 704 corresponding to the other suction cups 7 that are not adsorbed to the film are controlled to open, so that the other suction cups 7 that are not adsorbed to the film adsorb the film, and then the cutting mechanism 4 is controlled to cut the film, and then all the adjusting components 6 are controlled to align the film with the battery cell and the glass plate on the conveyor belt 203 and lay it on the top of the glass plate or the battery cell. When it is necessary to open a hole in the film on the top of the battery cell, the solenoid valve 704 corresponding to one of the suction cups 7 is controlled to be closed, and the connecting valve is opened so that the suction cup 7 no longer adsorbs the film, and then the adjusting component 6 corresponding to the suction cup 7 is controlled to adjust The suction cup 7 is adjusted to move to the position where the hole needs to be opened, and then the electromagnetic valve 704 corresponding to the suction cup 7 is opened again, and the connecting valve is closed, so that the suction cup 7 adsorbs the film, and at the same time the heating component is controlled to heat, so that the film corresponding to the circular adsorption cavity 702 is stretched and deformed under the action of negative pressure, and bulges upward, and then the first electric telescopic rod 602 corresponding to all the adjustment components 6 is controlled to contract, so that the film is away from the battery cell by a preset distance, that is, a certain gap is maintained between the film and the battery cell, and the gap can be set according to actual production needs, and then the heating component is turned off. After cooling, the two electromagnets in the same hole opening component 707 are controlled to be energized and generate magnetic attraction. Under the magnetic attraction Under the action, the scissors 7072 are brought close to each other. Since the film corresponding to the circular adsorption cavity 702 is stretched and deformed and bulges upward, the scissors 7072 cut the bulging film of the circular adsorption cavity 702, so that the device can cut out eight openings distributed in a circular array, and then control the electromagnet to cut off the power, and under the action of the reset spring 7073, the scissors 7072 are reset, so as to prepare for the subsequent extension of the telescopic column 710, and then the telescopic column 710 is controlled to extend to extend the sealing block 712. Under the action of the thrust, the part of the film at the bottom of the first cavity 701 that has not been cut is pierced, so that the extension line of the bus bar on the battery cell can pass through the center of the opening.

[0049] When the cutting assembly 4 fails, Fig.11As shown in the figure, by controlling the extension of the telescopic column 710, the extension of the telescopic column 710 will push the fixed shaft 705 and the scissors 7072 to move downward as a whole, but since the fixed shaft 705 and the scissors 7072 are hinged by the reset torsion spring 7074, the scissors 7072 are in a horizontal position at this time, and the bottom of the scissors 7072 is blocked by the suction cup 7. Under the blocking effect of the suction cup 7, the scissors 7072 overcome the reset torsion spring 7074 of the hinge assembly and then rotate upward, that is, rotate toward the top of the rotation groove 711. As the telescopic column 710 extends, the scissors 7072 rotates from a horizontal position to a vertical position, and then continues to extend. Under the action of the length, the scissors 7072 are extended. Since the scissors 7072 are extended from the first cavity 701, the scissors 7072 are restored to a horizontal position under the action of the reset torsion spring 7074. Then, by controlling the electromagnet on one of the scissors 7072 to be energized, under the action of the electromagnet and the ferromagnetic layer 709, the scissors 7072 overcome the reset torsion spring 7074 of the hinge assembly and rotate toward the ferromagnetic layer 709 and engage with it, thereby turning the scissors 7072 from a horizontal state to a vertical state. Then, by controlling the adjustment assembly 6, the scissors 7072 replace the cutting mechanism 4 to cut the film.

[0050] The present invention also provides a method for laying a battery packaging film, comprising the following steps:

[0051] Step 1: Control the feeding mechanism 3 to transport the glass plate with the battery sheet on the top to the laying position, then control the adjustment component 6 far away from the film row to adjust, so that the suction cup 7 approaches and contacts the feeding mechanism 3, and at the same time control the remaining adjustment components 6 to adjust to make way for the suction cup 7 far away from the film row to move toward the feeding mechanism 3, and then control the solenoid valve 704 in the suction cup 7 far away from the film row to open, so that the suction cup 7 far away from the film row absorbs the film on the feeding mechanism 3, and then control the feeding mechanism 3 to transport the film, and at the same time control the adjustment component 6 far away from the film row to drive the suction cup 7 to move to the side away from the feeding mechanism 3 until the film is the same length as the laid photovoltaic cell;

[0052] Step 2: Control the adjustment components 6 corresponding to the other suction cups 7 that are not attached to the film to adjust so that the suction cups 7 are in contact with the film, and then control the solenoid valves 704 corresponding to the other suction cups 7 that are not attached to the film to open, so that the other suction cups 7 that are not attached to the film are attached to the film;

[0053] Step 3: Control the cutting mechanism 4 to cut the adhesive film, and then control all the adjusting components 6 to adjust so that the adhesive film is aligned with the battery sheet and the glass plate on the feeding mechanism 3 and laid on the top of the glass plate or the battery sheet;

[0054] Step 4: When it is necessary to make a hole in the adhesive film on the top of the battery cell, the electromagnetic valve 704 corresponding to one of the suction cups 7 is controlled to be closed, and the connecting valve is opened so that the suction cup 7 no longer adsorbs the adhesive film, and then the adjusting component 6 corresponding to the suction cup 7 is controlled to adjust so that the suction cup 7 moves to the location where the hole needs to be made, and then the electromagnetic valve 704 corresponding to the suction cup 7 is opened again, and the connecting valve is closed so that the suction cup 7 adsorbs the adhesive film, and at the same time, the heating component is controlled to heat, so that the adhesive film corresponding to the circular adsorption cavity 702 is stretched and deformed under the action of negative pressure, and bulges upward, and then all the adjusting components 6 are controlled to adjust so that the adhesive film is away from the battery cell by a preset distance, and then the heating component is closed;
