Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panel production, and in particular to photovoltaic panel production equipment. Background Art

[0002] Solar photovoltaic glass is a special glass that can generate electricity by using solar radiation through lamination into solar cells and has relevant current extraction devices and cables. It is composed of low-iron glass, solar cells, film, back glass, and special metal wires. The solar cells are sealed between a piece of low-iron glass and a piece of back glass through film. It is a new high-tech glass product for construction. The use of low-iron glass to cover the solar cells can ensure high sunlight transmittance. The tempered low-iron glass also has stronger wind pressure resistance and the ability to withstand large temperature changes between day and night. In the production process of photovoltaic glass, the packaging technology between layers can ensure that the glass is subjected to balanced stress, ensuring that it does not deform and the sealing is well controlled.

[0003] After searching, a Chinese invention patent disclosed a photovoltaic panel production and pressing equipment with publication number CN116825880A, which relates to the technical field of photovoltaic panel production, including a mounting frame, the upper surface of the mounting frame is recessed in the middle, the outer wall of the mounting frame is rotatably connected to a transmission roller through a bearing, the outer wall of the mounting frame is fixedly connected to an electric push rod, the upper end of the electric push rod is fixedly connected to a bracket, the outer wall of the bracket is fixedly connected to a cover plate, the upper side of the outer wall of the cover plate is fixedly connected to a hydraulic press, the lower end of the hydraulic press penetrates the cover plate and extends to the lower side of the cover plate and is fixedly connected to a pressure plate, two sealing plates are fixedly connected to both sides of the outer wall of the cover plate, and two slots are provided on the upper surface of the mounting frame corresponding to the position of the sealing plate. The present invention blows out excess gas to clean the transmission roller when the bottom sealing plate moves up, thereby avoiding the displacement of the plate layer caused by the bumps during the transportation of the photovoltaic panels, and has the characteristics of strong practicality.

[0004] However, the above device has the problem that the roller conveyor serves as a working platform. During pressing, the contact area between the photovoltaic panel and the roller is small, so the photovoltaic panel is prone to breakage and damage under high pressure. At the same time, during pressing, due to mechanical extrusion, the pressure between the pressing plate and the photovoltaic panel is difficult to adjust. Therefore, when the pressure between the pressing plate and the photovoltaic panel is too high, it is easy to cause damage to the photovoltaic panel or the pressing plate. When the photovoltaic panel is unevenly stressed, the layers are prone to offset, resulting in stratification of the photovoltaic panel.

The support member pushes the tensioning wheel outward to tension the second conveyor belt, thereby adjusting the slight offset of the photovoltaic panel. The support member drives the fixing member to move toward the second conveyor belt during the sliding process. The fixing member is used to return the multi-layer offset of the photovoltaic panel, so that it can be continuously and automatically adjusted during the process of pressing the photovoltaic panel, thereby ensuring that the photovoltaic panel will not be offset and layered after pressing is completed.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0037] Example 1

[0038] In the actual production process, photovoltaic panels are usually prone to breakage and damage due to the high pressure. At the same time, during pressing, due to mechanical extrusion, the pressure between the pressing plate and the photovoltaic panel is difficult to adjust. Therefore, when the pressure between the pressing plate and the photovoltaic panel is too high, it is easy to cause damage to the photovoltaic panel or the pressing plate. This embodiment is specially invented to solve the above problems.

The outer surface of the connecting shaft 32 is meshed with a second conveyor belt 33, and the second conveyor belt 33 is meshed with the outer surface of the tensioning shaft 31. The second conveyor belt 33 is made of elastic heat-resistant material, and the output end of the conveying motor 34 is fixedly connected to one of the connecting shafts 32.

[0044] See also Figure 4 , Figure 6 As shown, the reverse punching assembly 7 includes a telescopic sleeve 71 fixedly connected to the base frame 1 and a reciprocating motor 72 fixedly connected to the base frame 1, a telescopic frame 73 is slidably connected inside the telescopic sleeve 71, and a punching plate 74 is fixed to the upper end of the telescopic frame 73.

[0046] See also Figure 3 , Figure 8 As shown, the stamping plate 74 is located in the inner cavity of the second conveyor belt 33 , a limiting plate 78 is fixed on the upper end of the stamping plate 74 , and an electric heating block is fixedly connected to the stamping plate 74 .

[0047] See also Figure 7 As shown, the lower end surface of the extrusion plate 52 is fixedly connected with an exhaust pressure plate 521, the exhaust pressure plate 521 is an arc-shaped structure, and the exhaust pressure plate 521 is made of elastic material.

[0048] Working principle: When working, the photovoltaic panel with the pressure plate is placed on one side of the outer surface of the second conveyor belt 33. At this time, the conveying motor 34 is started to rotate the output end of the conveying motor 34, so the connecting shaft 32 at the output end of the conveying motor 34 rotates, so the second conveyor belt 33 rotates through the tensioning shaft 31 on the outer surface of the connecting shaft 32, so that the photovoltaic panel with the pressure plate moves to the top of the reverse stamping assembly 7, and the electric heating block on the upper end surface of the stamping plate 74 is started at this time to prevent the glue from solidifying and facilitate the pressing plate, and further start the reciprocating motor 72 to rotate the output end of the reciprocating motor 72, thereby driving the second worm connected to the output end of the reciprocating motor 72. The rod 75 rotates, thereby rotating the second worm gear 77 meshing with the second worm 75, so that the third connecting rod 76 makes a circular motion around the second worm gear 77. At this time, since the third connecting rod 76 is rotationally connected to the stamping plate 74, the stamping plate 74 rises, thereby causing the telescopic frame 73 to slide upward, and at the same time starting the driving assembly 2, so that the output end of the driving motor 21 rotates, thereby driving the driving wheel 22 connected to the output end of the driving motor 21 to rotate, thereby causing the first conveyor belt 23 to rotate, and further causing the driven wheel 24 to rotate, so that the first worm 25 on both sides rotate, and further causing the first worm gears 26 on both sides to rotate, so that the thread The rod 27 rotates, thereby reducing the height of the threaded sleeve 28, thereby causing the buffer frame 41 to move downward, so that the extrusion assembly 5 generates downward pressure on the pressure plate. At this time, the arc-shaped exhaust pressure plate 521 is used to gradually increase the contact area between the pressure plate and the photovoltaic panel, thereby facilitating the extrusion and discharge of air between the photovoltaic panel and the pressure plate. At the same time, when the interaction force between the extrusion assembly 5 and the pressure plate is large, the first connecting rod 51 rotates, thereby pushing the sliders 44 closer to each other, and the first elastic member 43 contracts to absorb part of the interaction force generated between the extrusion plate 52 and the pressure plate. The first elastic member 43 is adjusted according to the force. The same degree of contraction makes the interaction force between the extrusion plate 52 and the pressing plate maintained in a stable range, thereby avoiding excessive interaction force between the extrusion plate 52 and the pressing plate causing damage to the photovoltaic panel. Similarly, when the pressing plate is completed, the output end of the drive motor 21 reverses to drive the driving wheel 22, the first conveyor belt 23, the driven wheel 24 and the first worm 25 to rotate in the opposite direction, thereby causing the first worm gear 26 to rotate in the opposite direction, and further causing the threaded rod 27 to reverse, driving the threaded sleeve 28, the buffer assembly 4 and the extrusion assembly 5 to rise in height. At this time, the conveying motor 34 is started to drive the second conveyor belt 33 to rotate, thereby discharging the pressed photovoltaic panel out of the device.

[0049] Example 2

[0050] In actual use, it is found that after the extrusion plate 52 contacts the photovoltaic panel, the photovoltaic panel may be subjected to uneven force, which may easily cause slight offsets between different layers of the photovoltaic panel, resulting in stratification of the photovoltaic panel. Therefore, in order to further ensure the stability of pressing, when slight offsets occur between different layers of the photovoltaic panel, the photovoltaic panel can be quickly and automatically adjusted back to the original position.

[0051] See also Figure 3 , Figure 8 The return assembly 6 shown includes a support member 61 sliding on the base frame 1, the support member 61 is rotatably connected to a second connecting rod 62, the end of the second connecting rod 62 away from the support member 61 is rotatably connected to a fixing member 63, and both ends of the fixing member 63 are slidably connected to the side walls of the base frame 1.

[0052] See also Figure 3 , Figure 8 As shown, the conveying assembly 3 includes two tensioning shafts 31 which are rotatably connected to the base frame 1 respectively, and a sliding rod 311 is slidably connected inside each tensioning shaft 31, and both ends of each sliding rod 311 are commonly fixedly connected with a tensioning wheel 312, and the outer surface of each tensioning wheel 312 is in contact with the outer surface of the fixing member 63. A second elastic member 313 is sleeved on the outer wall of each sliding rod 311, and both ends of the second elastic member 313 are respectively connected to the tensioning wheel 312 and the tensioning shaft 31.

[0053] On the basis of the above embodiment, during use, when the force is uneven, the extrusion plate 52 will tilt, thereby causing the two rotating shafts 53 to tilt. During the process of continuing to press down, the rotating shaft 53 on the side with greater force preferentially contacts the support member 61, pushing the support member 61 to slide to the side with less force. After the support member 61 is subjected to force, it pushes the tensioning wheel 312, and the second elastic member 313 contracts. The tensioning wheel 312 slides inside the tensioning shaft 31 through the sliding rod 311, thereby tensioning the second conveyor belt 33. As the support member 61 moves, the second connecting rod 62 rotates, driving the fixing member 63 to slide downward on the base frame 1 to straighten the photovoltaic panel. When the photovoltaic panel is subjected to uniform force, the extrusion plate 52 no longer tilts, and the rotating shaft 53 pushes the support member 61 to return to its original position. At this time, the second elastic member 313 relaxes and pushes the tensioning wheel 312 to return to its original position, thereby preventing the photovoltaic panel from being slightly offset during pressing.
