DETAILED DESCRIPTION

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments.

[0036] As Figures 1 to 5As shown, the present embodiment proposes a photovoltaic cell panel laminated production equipment, which comprises a rack 1, a feeding assembly 2 arranged on one side of the top of the rack 1, a discharging assembly 3 arranged on the other side of the top of the rack 1, and a laminated machine bin 101 arranged on the top of the rack 1. The top of the rack 1 is provided with a limiting assembly located above the feeding assembly 2, which comprises a pushing component 5 arranged on the top of the rack 1, a clamping component 6 arranged at the output end of the pushing component 5, and an extrusion component 8 arranged at the bottom of the clamping component 6. The pushing component 5 can drive the extrusion component 8 to press and limit the top of the photovoltaic panel while driving the clamping component 6 to clamp the two sides of the photovoltaic panel placed on the feeding assembly 2. The side wall of the rack 1 is also provided with a walking assembly 7 for driving the fixed photovoltaic panel to move horizontally towards the laminated machine bin 101. The top of the laminated machine bin 101 is provided with a processing assembly for preheating and filtering the pressurized gas, which comprises a preheating component 11 arranged on the top of the laminated machine bin 101 and a pressurized filtering component 12 arranged between the preheating component 11 and the laminated machine bin 101.

[0037] When it is necessary to laminate the photovoltaic cell panel, the photovoltaic panel is first placed on the feeding assembly 2, and then the pushing component 5 is driven to work to drive the clamping component 6 to clamp the two sides of the photovoltaic panel. At the same time, the pushing component 5 can also drive the extrusion component 8 to press the upper surface of the photovoltaic panel, so as to fully limit the photovoltaic panel. Then the walking assembly 7 is driven to move the fixed photovoltaic panel to the feeding port of the laminated machine bin 101. The pushing component 5 is controlled to drive the clamping component 6 and the extrusion component 8 to move reversely to release the photovoltaic panel. At this time, the photovoltaic panel is transferred to the laminated machine bin 101 through the feeding assembly 2 for laminating treatment, so as to improve the stability of the photovoltaic panel transmission and prevent the photovoltaic panel from being tilted and conveyed into the laminated machine bin 101 due to shaking displacement caused by equipment vibration during the conveying process, thereby affecting the laminating quality. In addition, when the photovoltaic panel is laminated, the preheating component 11 and the pressurized filtering component 12 can be used to draw the outside air into the laminated machine bin 101 for pressurization operation. At the same time, the outside air drawn can be preheated and filtered to prevent the outside air with low temperature from being directly filled into the laminated machine bin 101 to cause the EVA in the photovoltaic panel assembly to be cured in advance and affect the laminating effect. Finally, when the photovoltaic panel assembly is laminated, it will be output to the processing assembly 3. The discharging assembly 3 is composed of a conveying belt, which can convey the output photovoltaic cell panel assembly to the next process.

[0038] As Figure 5 , Figure 6 and Figure 7As shown, as a preferred embodiment, on the basis of the above mode, further, the advancing component 5 comprises a moving frame 4 slidingly arranged on the top of the frame 1, a cylinder 501 arranged on the top of the moving frame 4, a piston column 502 arranged on the output end of the cylinder 501, and a mounting plate 503 arranged on the bottom of the piston column 502;

[0039] The clamping component 6 comprises sliding plates 601 arranged on both sides of the mounting plate 503 and slidingly connected with the inner wall of the moving frame 4, clamping plates 603 slidingly arranged on both sides of the moving frame 4, and push-pull rods 602 movably arranged between the top of the clamping plates 603 and the bottom of the sliding plates 601, wherein the side wall of the moving frame 4 is provided with limiting plates 604, the back of the clamping plates 603 is provided with guide rods 605, and the guide rods 605 are slidingly connected with the limiting plates 604, so that the clamping plates 603 can be limited and normally slide under the extrusion of the push-pull rods 602;

[0040] The extruding component 8 comprises connecting plates 801 arranged on both sides of the mounting plate 503, fixed cylinders 802 arranged on the bottom of the connecting plates 801, pressing columns 803 slidingly arranged in the fixed cylinders 802, pressing pads 804 arranged on the bottom of the pressing columns 803, and first springs 805 arranged between the top of the pressing columns 803 and the inner top wall of the fixed cylinders 802;

[0041] The walking assembly 7 comprises a fixed plate 102 arranged on the side wall of the frame 1, a first motor 701 arranged on the side wall of the fixed plate 102, a lead screw 702 arranged on the output shaft of the first motor 701, and a moving seat 703 arranged on the inner wall of the moving frame 4 and screw-connected with the lead screw 702;

[0042] When the photovoltaic panel assembly needs to be transported, the air cylinder 501 is started to work, the mounting plate 503 is driven to move downward by the piston column 502, the mounting plate 503 drives the sliding plate 601 to move downward and press the push-pull rod 602, so that the push-pull rod 602 pushes the clamping plate 603 to move towards the middle of the rack 1, so that the photovoltaic panel on both sides can be clamped by the two clamping plates 603 symmetrically arranged on both sides of the rack 1, and sponge pads can be arranged on the inner side of the clamping plate 603 to protect the side wall of the photovoltaic panel and prevent the clamping plate 603 from scratching the photovoltaic panel. At the same time, the downward moving mounting plate 503 also drives the fixed cylinder 802 and the pressing column 803 to move downward, so that the pressing pad 804 at the bottom of the pressing column 803 abuts against the upper surface of the photovoltaic panel. At this time, when the pressing pad 804 is blocked by the photovoltaic panel, it will drive the pressing column 803 to slide towards the inside of the fixed cylinder 802, and the first spring 805 will press the pressing column 803 to make the pressing pad 804 always abut against the surface of the photovoltaic panel, so as to press and position the photovoltaic panel, and the photovoltaic panel will not be pressed to death. Then the first motor 701 is started to work to drive the lead screw 702 to rotate, and the lead screw 702 drives the moving frame 4 to move towards the laminating machine bin 101 through the moving seat 703, so that the photovoltaic panel can be kept in a flat state and will not be displaced. When the photovoltaic panel is moved to the inlet of the laminating machine bin 101, the air cylinder 501 drives the piston column 502 to move upward, so as to drive the clamping plate 603 and the pressing pad 804 to move away from the photovoltaic panel. At this time, the photovoltaic panel is released and will be transported to the inside of the laminating machine bin 101 under the action of the feeding assembly 2 to realize laminating treatment.

[0043] The feeding assembly 2 comprises a plurality of rollers 201 rotatably arranged on one side of the top of the rack 1, rubber cylinders 202 sleeved outside the rollers 201, and a second motor 203 arranged on the side wall of the rack 1. The output shaft of the second motor 203 is connected with one roller 201 close to the laminating machine bin 101. The photovoltaic panel abuts against the rubber cylinder 202 on the roller 201 after being fixed. When the moving frame 4 is moved by the first motor 701 and the lead screw 702, the photovoltaic panel will slide on the surface of the rubber cylinder 202, and the rolling rubber cylinder 202 can also press the bottom of the photovoltaic panel, so that the photovoltaic panel assembly composed of glass, EVA, connected single cells, EVA and back plate can be more closely attached together. The rubber cylinder 202 has a buffering protection effect and can prevent the photovoltaic panel from being damaged under pressure. When the photovoltaic panel is released at the inlet of the laminating machine bin 101, the second motor 203 is started to work to drive one roller 201 close to the laminating machine bin 101 to rotate. At this time, the photovoltaic panel will contact the rotating roller 201 and be transported to the inside of the laminating machine bin 101 under the action of the rotating friction of the rubber cylinder 202.

[0044] As Figure 5 , Figure 6 , Figure 11And Figure 12 As shown in the preferred embodiment, on the basis of the above-mentioned mode, further, the moving frame 4 is provided with a pressing assembly 9, the pressing assembly 9 comprises a slide rod 901 slidingly arranged on the top of the moving frame 4 and extending downward through the slide plate 601, a pressing plate 902 arranged on the bottom of the slide rod 901, and a reciprocating component 10 arranged on the moving frame 4 and capable of driving the slide rod 901 to slide up and down when the moving frame 4 moves along the length direction of the rack 1;

[0045] The reciprocating component 10 comprises a gear 1001 rotatably arranged on the side wall of the moving frame 4, a tooth groove 1002 arranged on the top of the fixed plate 102, a rotating rod 1004 rotatably arranged on the top of the moving frame 4, a synchronous belt 1003 drivingly arranged between the rotating rod 1004 and the end of the gear 1001, a cam 1005 arranged on the end of the rotating rod 1004 away from the synchronous belt 1003, a roller 1006 rotatably arranged on the top of the slide rod 901, and a second spring 1007 sleeved on the rod wall of the slide rod 901;

[0046] When the moving frame 4 is driven to move by the first motor 701 and the lead screw 702, the gear 1001 on the side wall of the moving frame 4 will rotate with the tooth groove 1002, the gear 1001 will drive the rotating rod 1004 and the cam 1005 to rotate through the synchronous belt 1003, when the cam 1005 rotates to the small head part and contacts the roller 1006, it will extrude the roller 1006 and the slide rod 901 to slide downward and make the second spring 1007 compressed, and when the cam 1005 rotates to the large head part and contacts the roller 1006, the pressure on the second spring 1007 is released, which drives the slide rod 901 to move upward and reset, so that the cam 1005 can drive the slide rod 901 to reciprocate up and down when rotating, thereby driving the pressing plate 902 at the bottom of the slide rod 901 to pop up and down, continuously extruding the edge part of the photovoltaic panel assembly, improving the pressing tightness of the photovoltaic panel assembly composed of glass, EVA, connected monomer cells, EVA and back plate, preventing the edge of the photovoltaic panel assembly from being warped, and facilitating subsequent better lamination of the photovoltaic panel. In addition, in order to prevent the parts in the reciprocating component 10 from being exposed to the outside and being touched by foreign matters to affect normal operation, a protective shell can be arranged on the side wall and the top of the moving frame 4 to protect the gear 1001, the synchronous belt 1003, the cam 1005, the roller 1006 and the second spring 1007, so as to avoid the parts from being contacted by foreign matters to affect the normal operation of the equipment.

[0047] As Figure 2 , Figure 8 , Figure 9 and Figure 10As shown, as a preferred embodiment, on the basis of the above-mentioned mode, further, the preheating component 11 comprises a preheating box 1101 arranged at the top of the laminating machine cabin 101, an air suction pump 1102 arranged at the top of the preheating box 1101, a plurality of electric heating plates 1103 distributed in the inner wall of the preheating box 1101 in a staggered manner, a plurality of rotating shafts 1104 arranged in the reserved gap between the electric heating plates 1103 and the inner wall of the preheating box 1101, and a plurality of fan blades 1105 arranged on the outer wall of the rotating shafts 1104;

[0048] The pressurized filtering component 12 comprises an air charging pump 1201 arranged at the side wall of the preheating box 1101, an air pipe 1202 arranged between the air charging pump 1201 and the laminating machine cabin 101, a filter cartridge 1203 arranged outside the air pipe 1202, and an air filter core 1204 and an activated carbon adsorption layer 1205 arranged inside the filter cartridge 1203;

[0049] When the photovoltaic panel is transported into the laminating machine cabin 101 for laminating treatment, the air suction pump 1102 can be started to suck external air into the preheating box 1101, and the air charging pump 1201 can be started to work to charge air into the laminating machine cabin 101 for pressurization, so as to facilitate the laminating machine cabin 101 to better laminate the photovoltaic panel. Meanwhile, the power supply control electric heating plate 1103 inside the preheating box 1101 is started to work to heat the air sucked into the preheating box 1101. The heating wire inside the electric heating plate 1103 is in a serpentine shape, which can uniformly heat the air in the preheating box 1101. The staggered electric heating plates 1103 can block the gas flowing in the preheating box 1101, so as to increase the residence time of the gas in the preheating box 1101. Moreover, the fan blades 1105 can also block the gas, and the gas sucked by the air charging pump 1201 will impact the fan blades 1105 to make the fan blades 1105 rotate and agitate the gas, so as to improve the uniformity of the heated air. When the hot air is sucked into the air pipe 1202, it will pass through the filter cartridge 1203. The air filter core 1204 can filter and block the dust and impurities in the gas, and the activated carbon adsorption layer 1205 can adsorb and treat the harmful impurities in the gas, so as to improve the quality of the gas. Therefore, by heating and filtering the external air and then charging it into the laminating machine cabin 101 for pressurization, it can not only prevent the laminating machine cabin 101 from being charged with external air with a stable low temperature, which will cause the EVA to be cured in advance and affect the laminating quality of the photovoltaic panel, but also prevent the dust and impurities in the gas from contacting the photovoltaic panel assembly and affecting the laminating quality.

[0050] The working principle of the present application is: when the photovoltaic panel needs to be laminated, first place the photovoltaic panel on the feeding assembly 2, then start the air cylinder 501 to work to drive the mounting plate 503 to move downward, the mounting plate 503 will drive the sliding plate 601 to move downward and extrude the push-pull rod 602, so that the push-pull rod 602 pushes the clamping plate 603 to move towards the middle of the rack 1, then the two sides of the photovoltaic panel can be clamped, at the same time, the downward moving mounting plate 503 will also drive the fixed cylinder 802 and the pressing column 803 to move downward, so that the pressing pad 804 at the bottom of the pressing column 803 abuts against the upper surface of the photovoltaic panel, so that the photovoltaic panel can be extruded and positioned, then start the first motor 701 to work to drive the lead screw 702 to rotate, the lead screw 702 will drive the moving frame 4 to move towards the laminator warehouse 101 through the moving seat 703, so that the photovoltaic panel can be kept in a flat state and will not be displaced, when the photovoltaic panel is moved to the feeding port of the laminator warehouse 101, control the air cylinder 501 to drive the piston column 502 to move upward, so that the clamping plate 603 and the pressing pad 804 can be away from the photovoltaic panel, at this time the photovoltaic panel is loosened, under the action of the feeding assembly 2 it will be transported into the laminator warehouse 101 to realize laminating treatment. And when the moving frame 4 moves, through the gear 1001 cooperating with the tooth groove 1002, the gear 1001 can be rotated and drive the cam 1005 to rotate through the synchronous belt 1003 and the rotating rod 1004, then drive the sliding rod 901 and the pressing plate 902 to move up and down, constantly extruding the edge of the photovoltaic panel assembly, improving the pressing tightness of the photovoltaic panel assembly composed of glass, EVA, connected monomer battery, EVA and back plate, preventing the edge of the photovoltaic panel assembly from being warped, facilitating better laminating treatment of the photovoltaic panel.When the photovoltaic panel is conveyed into the lamination machine chamber 101 for lamination, the air pump 1102 is started to draw outside air into the preheating box 1101, and the air charging pump 1201 is started to work to charge air into the lamination machine chamber 101 for pressure boosting, so as to facilitate the lamination machine chamber 101 to better laminate the photovoltaic panel. Meanwhile, the power control electric heating plate 1103 in the preheating box 1101 is started to work to heat the air drawn into the preheating box 1101. The staggered electric heating plates 1103 can block the air flowing in the preheating box 1101, so as to increase the residence time of the air in the preheating box 1101. The fan blades 1105 can also hinder the air. The air is drawn by the air charging pump 1201 to impact the fan blades 1105, so as to rotate the fan blades 1105 and stir the air, thereby further improving the air heating uniformity. When the hot air passes through the filter cylinder 1203, the air filter core 1204 can filter and block the dust and impurities in the air, and the activated carbon adsorption layer 1205 can adsorb and treat the harmful impurities in the air, so as to improve the air quality. Therefore, the outside air is heated and filtered and then charged into the lamination machine chamber 101 for pressure boosting, which can not only prevent the outside air from being charged into the lamination machine chamber 101 due to the too low stable air pressure, so as to affect the EVA curing and the photovoltaic panel lamination quality, but also prevent the dust and impurities in the air from contacting the photovoltaic panel assembly to affect the lamination quality.
