Description

Technical Field

[0001] This utility model relates to the field of heliostat manufacturing technology, and in particular to a heliostat secondary curing mechanism. Background Technology

[0002] Heliostats are the core concentrating components of tower solar thermal power generation systems. Their function is to track the sun's position in real time through a high-precision array of reflective mirrors, reflecting and focusing solar radiation energy onto a receiver at the top of the solar collector tower.

[0003] Heliostats consist of a heliostat backplate and heliostat lenses. To achieve automated assembly of heliostats, the current heliostat production line assembles them fully automatically. The assembly process is as follows: First, a loading robotic arm picks up the lens and places it face down in a tray that is circulated on a conveyor belt. The lens is then transported to an adhesive applicator robotic arm where adhesive is applied to the adhesive points on the back of the lens. Next, the lens is transported to a backplate loading robotic arm, which picks up the heliostat backplate, aligns the adhesive part of the backplate with the adhesive points, and places it on the lens. Once the adhesive has fully cured, the heliostat assembly is complete. Finally, the assembled heliostat is removed from the tray by a robotic arm and stored.

[0004] Because a single heliostat lens has a large area, the processing line for heliostats requires a significant amount of factory space. If the lens is completely cured directly on the production line, the length of the entire line needs to be significantly increased, resulting in low space utilization, especially in factories with limited space, where the layout of the heliostat production line cannot be accommodated. If the lens is removed and laid flat to cure, it requires a large additional space for storing the lens, and an additional step is needed after curing, requiring manual collection of the lens, which is time-consuming and labor-intensive. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides: 1. A heliostat secondary curing mechanism, characterized in that it comprises:

[0006] The double-layer frame includes a first conveying mechanism and a second conveying mechanism. The first conveying mechanism moves towards the lifting frame, while the second conveying mechanism moves away from the lifting frame. The end of the second conveying mechanism is provided with a guide mechanism and a limiting block.

[0007] The lifting frame includes an outer frame, a vertical material transfer mechanism vertically disposed in the outer frame, and a horizontal material transfer mechanism horizontally disposed in the vertical material transfer mechanism. The vertical material transfer mechanism is used to drive the horizontal material transfer mechanism to move vertically to a first height level with the first conveying mechanism and a second height level with the second conveying mechanism.

[0008] Specifically, the vertical material transfer mechanism is installed on the side of the outer frame away from the double-layer frame, and the vertical material transfer mechanism includes a pneumatic slide rail and positioning slide rails arranged on both sides of the pneumatic slide rail.

[0012] Specifically, a support column is provided on the bottom front side of the outer frame, and rubber shock-absorbing blocks are provided on the support column.

[0013] Specifically, the guiding mechanism includes a guide wall and a corner cylinder. The guide wall includes an inclined guiding section and a straight limiting section.

[0016] 1. This utility model establishes a secondary curing mechanism for heliostats. By using a double-layer frame and lifting frame design, it makes full use of the three-dimensional space and extends the cooling time of the heliostat within a limited floor area.

A guide mechanism and a limiting block are set at the end of the second conveying mechanism to correct and adjust the heliostat, so that the material transfer robot arm can grab the heliostat from the fixed point and remove it from the fixed point. No manual intervention is required during the secondary curing process. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-5As shown, this utility model provides a heliostat secondary curing mechanism, including a double-layer frame 91 and a lifting frame 92. The double-layer frame 91 is equipped with a first conveyor mechanism 911 and a second conveyor mechanism 912. The first conveyor mechanism 911 and the second conveyor mechanism 912 are belt conveyors, and the two conveyors move in opposite directions, driven by a first drive device and a second drive device respectively. It can be understood that the first conveyor mechanism 911 moves towards the lifting frame 92, transporting the heliostat into the lifting frame 92, while the second conveyor mechanism 912 moves away from the lifting frame 92, transporting the heliostat to the unloading section. Preferably, the first conveyor mechanism 911 is located on the upper layer, and the second conveyor mechanism 912 is located on the lower layer.

[0028] The heliostat includes heliostat lenses and a heliostat backplate. The heliostat backplate is in contact with the conveying mechanism, and the heliostat lenses are bonded to the heliostat backplate with adhesive. The heliostat secondary curing mechanism is set parallel to the heliostat production line. The adhesive is cured once in the heliostat production line and then picked up and moved to the secondary curing mechanism by the transfer robot arm 8. The heliostat makes full use of the three-dimensional space through the double-layer conveyor belt design, extending the cooling time of the heliostat within the limited space. The heliostat passes through the first conveying mechanism 911, the horizontal transfer mechanism 923, and the second conveying mechanism 912 in sequence, so that the adhesive applied between the heliostat backplate and the lenses is completely cured.

[0029] The lifting frame 92 includes an outer frame 921, a vertical material transfer mechanism 922 vertically disposed within the outer frame 921, and a horizontal material transfer mechanism 923 horizontally disposed within the vertical material transfer mechanism 922. The vertical material transfer mechanism 922 is fixedly installed on the side of the outer frame 921 away from the double-layer frame 91. The vertical material transfer mechanism 922 includes a pneumatic slide rail 9221 and positioning slide rails 9223 disposed on both sides of the pneumatic slide rail 9221. The horizontal material transfer mechanism 923 includes a base 9231, which is connected to the pneumatic slide rail 9221 and the positioning slide rails 9223. A material transfer conveyor belt 9232 is disposed on the base 9231.

[0030] Positioning slide rails 9223 are arranged opposite each other on both sides of pneumatic slide rail 9221. Each positioning slide rail 9223 is provided with two positioning sliders 9224, and the side walls of the two positioning sliders 9224 are connected to a fixing plate 9225. The pneumatic slide rail 9221 is positioned facing the double-layer frame 91, and a pneumatic slider 9222 is provided in the pneumatic slide rail 9221. The rear end of the base 9231 is fixedly connected to the pneumatic slider 9222 and the fixing plate 9225. Under the control of the control valve, the pneumatic slide rail 9221 causes the horizontal material transfer mechanism 923 to move up and down. The positioning slide rails 9223 and positioning sliders 9224 provide support for the movement of the horizontal material transfer mechanism 923 and distribute the load. At the same time, the use of double sliders further distributes the load of the horizontal material transfer mechanism 923 on the positioning slide rail 9223, avoids overload, and extends the service life of the equipment.

[0031] The material transfer conveyor belt 9232 is a belt-type conveyor belt. Driven by the third drive device to rotate forward or reverse, it moves the heliostat from the first conveyor mechanism 911 onto the material transfer conveyor belt 9232, or moves the heliostat from the material transfer conveyor belt 9232 onto the second conveyor mechanism 912. The end of the material transfer conveyor belt 9232 near the double-layer frame 91 is staggered with the first conveyor mechanism 911 and the second conveyor mechanism 912. When the pneumatic slide rail 9221 drives the material transfer conveyor belt 9232 to move to the first height and the second height, it is flush with the first conveyor mechanism 911 and the second conveyor mechanism 912, respectively. At the first height, the movement direction and speed of the material transfer conveyor belt 9232 match those of the first conveyor mechanism 911, and at the second height, the movement direction and speed of the material transfer conveyor belt 9232 match those of the second conveyor mechanism 912. The heliostat can move smoothly from the first conveying mechanism 911 to the horizontal transfer mechanism 923, or from the horizontal transfer mechanism 923 to the second conveying mechanism 912. A first proximity sensor 9233 is provided on the rear side of the transfer conveyor belt 9232. The first proximity sensor 9233 is vertically upward and electrically connected to the controller. When the heliostat moves above the first proximity sensor 9233 and the first proximity sensor 9233 detects the heliostat, that is, when the heliostat has completely moved onto the transfer conveyor belt 9232, the controller controls the transfer conveyor belt 9232 to stop, and then controls the pneumatic slide rail 9221 to lower the transfer conveyor belt 9232.

[0032] A support column 924 is provided on the bottom front side of the outer frame 921. A rubber shock absorber 925 is provided on the support column 924. The rubber shock absorber 925 can abut against the bottom of the base 9231 to prevent the heliostat from shifting due to vibration when the horizontal material transfer mechanism 923 moves to the bottom.

[0033] Guide mechanisms 913 are provided on both sides of the end of the second conveying mechanism 912 to correct and adjust the orientation of the heliostat, enabling the material handling robot arm 8 to grasp the heliostat from a fixed point and move it into the unloading mechanism. The guide mechanism 913 includes a guide wall 9131 and a corner cylinder 9132. The guide wall 9131 is fixedly installed in the second conveying mechanism 912 by multiple right-angle connectors. The guide wall 9131 includes an inclined guide section and a straight limiting section. The guide section of the guide wall 9131 bends inward from both sides. The corner cylinder 9132 is located on the inner side of the guide wall 9131. The guide wall 9131 and the corner cylinder 9132 guide and correct the orientation of the heliostat. The piston rod of the angle cylinder 9132 is provided with a rotating rod 9133 at its end. The rotating rod 9133 is located at the bend of the guide wall 9131. In the initial state of the angle cylinder 9132, the rotating rod 9133 is in a horizontal state, and the heliostat can pass normally. When the piston rod of the angle cylinder 9132 extends, the rotating rod 9133 rotates 90° and is vertically upward. The rotating rod 9133 abuts against the front side of the heliostat back plate and levels the heliostat. The second proximity sensor 915 is disposed between the two guide walls 9131, located in the inclined guide section of the guide wall 9131. The second proximity sensor 915 is vertically upward and electrically connected to the controller. When the heliostat moves above the second proximity sensor 915 and the second proximity sensor 915 detects the heliostat, the controller controls the piston rod of the angle cylinder 9132 to extend and abut against the front side of the heliostat back plate. After the adjustment is completed, the piston rod of the angle cylinder 9132 retracts, and the rotating rod 9133 rotates to a horizontal position to release the heliostat.

[0034] A limit block 914 is provided at the end of the second conveying mechanism 912. When the heliostat moves to the end of the second conveying mechanism 912, the limit block 914 stops the heliostat. A flexible protective layer is provided on the side wall of the limit block 914 that contacts the heliostat. The flexible protective layer can be made of rubber or the like to prevent the heliostat back plate from colliding with the limit block 914 and being damaged. A third proximity sensor 916 is also provided at the limit block 914. The third proximity sensor 916 is set vertically upward and electrically connected to the controller. When the heliostat moves above the third proximity sensor 916, and the third proximity sensor 916 detects the heliostat, it means that the heliostat has been conveyed and stopped at the end of the second conveying mechanism 912. The controller then controls the material handling robot arm 8 to grab the heliostat from the fixed point and move it into the unloading mechanism.

[0035] In use, the first conveying mechanism 911 and the second conveying mechanism 912 move continuously. The material transfer robotic arm 8 picks up the heliostat, whose adhesive has been preliminarily cured, and places it at the input end of the first conveying mechanism 911. Driven by the first conveying mechanism 911, the heliostat moves to the lifting frame 92. The third drive device rotates forward, causing the material transfer conveyor belt 9232 to rotate synchronously with the first conveying mechanism 911, moving the heliostat into the horizontal material transfer mechanism 923 and stopping at the first proximity sensor 9233. Then, the pneumatic slide rail 9221 is controlled. The horizontal transfer mechanism 923 is lowered, and the third drive device reverses to make the transfer conveyor belt 9232 and the second conveying mechanism 912 rotate synchronously, transferring the heliostat to the second conveying mechanism 912. Then, the horizontal transfer mechanism 923 rises back to its original position, and the heliostat moves to the guide mechanism 913 under the drive of the second conveying mechanism 912. After being corrected and adjusted by the guide wall 9131 and the corner cylinder 9132, the heliostat stops under the obstruction of the limit block 914. The transfer robot arm 8 picks up the heliostat from the fixed point and moves it to the unloading mechanism. The heliostat passes through the first conveying mechanism 911, the horizontal transfer mechanism 923 and the second conveying mechanism 912 in sequence, so that the adhesive applied between the heliostat back plate and the lens is completely cured.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
