Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic component laminating equipment, and in particular relates to a scratch-proof photovoltaic component laminating machine transmission belt pull rod and a photovoltaic component laminating machine. Background Art

[0002] Photovoltaic module laminators are equipment used to seal photovoltaic modules. With the development of the photovoltaic module market and increasingly fierce market competition, the performance requirements of laminators are becoming increasingly stringent. The effective laminating area of ​​the laminator is increasing, currently reaching a width of ≥3000mm, a length of ≥11500mm, and a number of laminated modules of ≥10. Since photovoltaic modules are transported via a high-temperature conveyor belt, which is connected to the drive chain by tie rods, the width of the conveyor belt is fixedly connected to the length of the tie rods, thereby securing the conveyor belt to the drive chain on both sides through the tie rods. During transportation, the tie rods and the conveyor belt jointly bear the weight of the photovoltaic modules. Therefore, as the transmission load of the high-temperature conveyor belt increases, the strength of the tie rods must also be increased accordingly. Currently, the strength of the conveyor belt tie rods must meet the required pulling force required to transport solar modules of ≥500kg. Since the tie rod is an assembly composed of multiple components, which are fixed together by welding, it is a welded structural component. After manufacturing, some parts of it have been bent. During the actual production process of packaging components on the laminator, the pulling force of the photovoltaic components is added, and its deformation is even greater. Due to the long span of the tie rod, it passes through the transmission shaft, heating plate or cooling plate, etc., and the bent tie rod can easily cause equipment failure or component damage, bringing unpredictable risks. For example, 1. The bent tie rod will scratch the upper surface of the heating (cooling) plate, causing damage to the plate surface. 2. When the tie rod moves around the outer surface of the transmission roller, it will scratch the outer surface of the transmission roller, causing equipment failure or component damage.

[0030] The utility model will be further described in detail through specific embodiments below, the following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the utility model.

[0031] As Figure 4 shown, the photovoltaic module laminator of the technical solution comprises a photovoltaic module laminating and curing unit and / or a cooling unit, the laminating and curing unit and the cooling unit both comprise a workbench for supporting and heating a photovoltaic module, a transmission belt 4 for transmitting the photovoltaic module, and a transmission chain for driving the transmission belt, the heating plate is provided with transmission rollers 4 at both ends, both sides of the transmission rollers are provided with sprockets, the transmission chain is connected to the sprockets on the corresponding sides, so that the heating plate has the transmission chain on both sides, the end of the transmission belt is fixedly arranged on a scratch-proof photovoltaic module laminator transmission belt pull rod (hereinafter referred to as a pull rod), the width direction of the transmission belt is consistent with the length direction of the pull rod, both ends of the pull rod are fixedly connected to the transmission chains on the corresponding sides, and the length direction of the pull rod is perpendicular to the running direction of the transmission belt, so that the transmission belt is wrapped around the workbench and the transmission rollers arranged in front and back, and forms a closed ring-shaped transmission belt. The laminator with the structure of the utility model adopts a scratch-proof photovoltaic module laminator transmission belt pull rod. When it is the laminating and curing unit, the workbench is a heating plate, and when it is the cooling unit, the workbench is a cooling plate.

[0032] As Figures 1-3As shown in the utility model embodiment structure's anti scratch type photovoltaic module laminator transmission belt pull rod 1 includes pull rod body 11 and through the roller frame fixedly arranged on the lower surface of pull rod body multiple rollers 15, each roller 15 is arranged along the length direction of pull rod body 11 interval, its interval is determined by the load it bears, the roller preferably along the length center line o-o of pull rod body is arranged, so that the stability of pull rod can be better maintained. The top of each roller is located in the same plane. The sliding friction between the pull rod and the contacted surface is converted into rolling friction. Preferably, the rollers are universal wheels, preferably steel ball rollers or bull eye rollers. Since such rollers are universal, they have good compliance with the pull rod and will not affect the forward movement of the pull rod due to the directionality of their rotation. Steel ball rollers or bull eye rollers also have high temperature resistance. The photovoltaic module laminator with the structure of the utility model has rollers arranged on the lower surface of the pull rod. When the pull rod moves above the upper surface 31 of the workbench and passes through the transmission roller 4, the lower surface of the pull rod can be supported, preventing the pull rod from bending and deforming and directly scratching the upper surface 31 of the heating plate or cooling plate and the outer surface 41 of the transmission roller. The hard extrusion sliding friction between the pull rod and the heating plate or cooling plate and the transmission roller due to deformation is converted into rolling friction, allowing the pull rod to smoothly pass through the above-mentioned surfaces without scratching, preventing scratches on the upper surface of the workbench and the surface of the transmission roller, and improving the overall life of the equipment.

[0033] As Figure 3 , Figure 7 In the utility model, the pull rod body 11 adopts a combined structure, preferably the following structure, including a main pull rod 18, a pull rod shaft 13, a shaft pressing plate assembly 14 and a pull rod seat 19. The pull rod shaft is a long rod used to pass through the cloth sleeve arranged at the end of the transmission belt, supporting and connecting the width direction of the end of the transmission belt. Fixing the transmission belt with the pull rod shaft passing through the cloth sleeve arranged at the end of the transmission belt is prior art and will not be described here. The main pull rod is a long rod, and the main pull rod and the pull rod shaft are arranged in parallel. The pull rod shaft is located at the side of the main pull rod. Usually, one main pull rod is equipped with two pull rod shafts, and the two pull rod shafts are located on both sides of the main pull rod. The shaft pressing plate assembly includes a support plate 142, which is U-shaped, preferably flat-bottomed U-shaped. The support plate can be integral, equal to or similar to the length of the pull rod shaft, or segmented. When the support plate is a segmented structure, multiple support plates are arranged along the length direction of the main pull rod. The support plate is fixedly arranged below the main pull rod and used to support the main pull rod. The width of the upper opening of the support plate is greater than the width of the main pull rod, so that there is space to accommodate the pull rod shaft on both sides or one side of the length of the main pull rod, referred to as the pull rod shaft accommodating space 110. The pull rod shaft is located in the pull rod shaft accommodating space. Figure 11As shown, the side wall of the bracket is provided with a connecting hole 111 for screw or quick release pin, and the side wall of the main pull rod is provided with a connecting hole 112 corresponding to the position and size of the connecting hole 1. The height of the connecting hole 1 and the connecting hole 2 is higher than the height of the pull rod shaft, so that when the screw or quick release pin passes through the connecting hole 1 and the connecting hole 2, the pull rod shaft is closed in the pull rod shaft containing space, preventing the pull rod shaft from escaping from the upper opening of the bracket. When one pull rod shaft is provided, the pull rod shaft containing space is provided on one side of the main pull rod. When two pull rod shafts are provided, the pull rod shaft containing space is provided on both sides of the main pull rod. In order to increase the overall strength of the pull rod body and the reliability of closing the pull rod shaft, the pressing plate assembly further comprises a pressing plate 141. The pressing plate is also an open U-shaped, the width of the opening part is greater than the width of the bottom, and the side wall is an outwardly opening inclined wall. An opening hole is provided on the inclined wall to allow the screw or quick release pin to be accommodated. The opening width is smaller than the opening width of the bracket and greater than the width of the main pull rod. The pressing plate is arranged on the upper surface of the main pull rod opposite to the bracket and is fixed and fastened with the main pull rod by a pressing plate fastener 143, covering or partially covering the corresponding part of the pull rod shaft. When the pressing plate is provided, the pressing plate is fixedly connected with the main pull rod by the pressing plate fastener, so that the pull rod shaft is closed by the pressing plate to prevent the pull rod shaft from escaping from the opening of the bracket. Therefore, the screw or quick release pin can not be arranged in the connecting hole 1 and the connecting hole 2 of the bracket. When the pull rod body is subjected to a large force, the pressing plate and the screw or quick release pin arranged in the connecting hole 1 and the connecting hole 2 can be arranged at the same time. The pressing plate is fixed on the front surface, which is convenient to operate when the installation and maintenance space is large. When the operation space is small, the quick release pin is used. The ball can be fixedly arranged on the back surface of the main pull rod through the threaded connection end, or can be fixedly arranged on the bottom lower surface of the bracket and fixedly connected with the back surface of the main pull rod. The pull rod seat 19 is arranged at both ends of the pull rod, and the baffle 113 is arranged on the pull rod connecting seat at both ends or both sides of the pull rod. The distance between the baffles is slightly greater than or equal to the length of the pull rod shaft, so that the pull rod shaft can be prevented from moving in the length direction during the process of pulling the transmission belt by the pull rod. The pressing plate and the screw or quick release pin constitute the anti-extraction part of the pull rod shaft.

[0034] When the laminating and curing unit and the cooling unit are included at the same time, the laminating and curing unit is located in front of the cooling unit, and the two units are arranged in front and back sequence. The worktables of the two units are arranged at the same height, and the transmission belt can share the surrounding heating worktable and cooling worktable.
