Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a heliostat lens feeding 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] A heliostat consists of a heliostat backplate and heliostat lenses. During assembly, the heliostat backplate needs to be glued to the back of the heliostat lenses. To automate the assembly of heliostats, a robotic arm is used to vacuum-pick up the heliostat lenses and place them onto a pre-positioned tray. The lenses then move with the tray, and after applying adhesive, they are assembled with the heliostat backplate, thus achieving high-precision assembly of the heliostat.

[0004] If there is an error in the position of the lens during loading, it cannot be accurately placed into the tray. Therefore, high precision is required for the loading position of heliostat lenses. In existing lens loading mechanisms, after the lens is moved by the conveyor, errors occur during the movement, resulting in the lens not being accurately placed into the tray. Therefore, a loading mechanism that can achieve precise loading of heliostat lenses is needed. Utility Model Content

[0026] 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.

In addition, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] like Figures 1-5As shown, this utility model provides a heliostat lens loading mechanism, including a flipping mechanism 11, a conveyor 12 and a positioning mechanism 13. The flipping mechanism 11 is located at the loading end and transfers the lens placed in the flipping mechanism 11 to the conveyor 12. The positioning mechanism 13 is provided in the conveyor 12 to lift and position the lens transported by the conveyor 12, so that the lens loading robot arm can accurately grab the lens and place it precisely on the tray.

[0029] The flipping mechanism 11 includes a first frame 111, with a flipping frame 113 hinged to the front end of the first frame 111. A flipping cylinder 112 is disposed in the first frame 111, and the piston rod of the flipping cylinder 112 is hinged to the flipping frame 113. The flipping frame 113 is rotated by the extension and retraction of the piston rod of the flipping cylinder 112. During loading, the flipping frame 113 is in its initial position, tilted. After loading, the flipping frame 113 flips to be parallel to the ground, slightly lower than the plane of the conveyor 12. The flipping frame 113 includes an L-shaped flipping section and a hinged section disposed on the rear side of the flipping section. The flipping section includes a flipping arm 1131, a bottom support section 1132 disposed at the bottom of the flipping arm 1131, and a limiting frame 1133 disposed on one side of the flipping arm 1131. A protective layer 14, which is a rubber protective layer, is disposed on the surfaces of the flipping arm 1131, the bottom support section 1132, and the limiting frame 1133 to prevent scratches and impacts to the lens. During loading, the front of the lens faces the flipping arm 1131, the bottom edge of the lens is placed on the bottom support 1132, and one side of the lens is attached to the edge of the limiting frame 1133 to position the loading position of the lens, so that the lens is transferred from the fixed point to the conveyor 12.

[0030] The hinge section includes a hinge shaft 1136, a hinge plate 1135, and an ear plate 1134. The hinge shaft 1136 is fixedly connected to the hinge plate 1135 and the ear plate 1134 by bolts. Bearing seats 1111 are respectively provided on both sides of the upper surface of the first frame 111. The hinge shaft 1136 is connected to the bearing seats 1111. A mounting base 1114 is provided in the first frame 111, and the tilting cylinder 112 is movably connected to the mounting base 1114. A through hole is provided in the first frame 111 above the tilting cylinder 112. The piston rod of the tilting cylinder 112 extends out of the through hole. A fork-shaped head 1121 is provided at the end of the piston rod. The fork-shaped head 1121 is hinged to the hinge plate 1135. The rotation of the tilting frame 113 is controlled by the extension and retraction of the piston rod of the tilting cylinder 112. A shock-absorbing block 1138 is provided on the rear side of the flipping frame 113. A damper 1113 is provided in the first frame 111 at the position corresponding to the shock-absorbing block 1138. A fixing seat 1112 for fixing the damper 1113 is provided on the first frame 111. When the flipping frame 113 flips, the damper 1113 contacts the shock-absorbing block 1138. The damper 1113 causes the flipping frame 113 to slowly descend when it flips to the lateral position, absorbing the vibration of the flipping frame 113 during the flipping process, so that the lens is smoothly transferred to the conveyor 12.

[0031] A loading sensor 1137 is installed at the loading position of the tilting frame 113. The loading sensor 1137 is electrically connected to the controller and is used to detect whether the lens is installed in place. A foot switch is installed in the safety area outside the tilting frame 113. After the operator places the lens on the tilting frame 113, he steps on the foot switch. The loading sensor 1137 detects whether there is a lens at the current position. If a lens is detected at the current position, the controller controls the piston rod of the tilting cylinder 112 to retract, transferring the lens to the conveyor 12.

[0032] Conveyor 12 is located behind the flipping mechanism 11 and is used to transport the lens from the flipping mechanism 11 to the positioning mechanism 13. The lens positioning mechanism is located behind the lens loading mechanism, providing a safe operating space for the lens loading robot arm and preventing collisions with personnel. Four conveyor belts 123 are installed in conveyor 12, spaced apart, and driven by motors and reducers. Positioning sensors 121 are installed along the lens transport path in conveyor 12. Positioning sensors 121 are electrically connected to the controller and are used to detect the real-time position of the heliostat lens. When the positioning sensor 121 detects that the lens has completely left the flipping frame 113, the controller controls the flipping frame 113 to return to its original position.

[0033] The positioning mechanism 13 is located at the rear of the conveyor 12 and includes a lifting mechanism and a lifting frame 133 mounted on the lifting mechanism. The lifting mechanism is mounted on a second frame 131 and consists of four lifting cylinders 132 fixedly mounted on the second frame 131. The piston rods of the lifting cylinders 132 are vertically upward, and the lifting frame 133 is mounted on the piston rods of the lifting cylinders 132. The lifting frame 133 includes four support frames 1335, which are staggered with the conveyor belt 123. When the lifting cylinders 132 lift the lifting frame 133, the height of the support frames 1335 is higher than the height of the conveyor belt 123, thus lifting the lens from the conveyor 12. At least on adjacent sides of the lifting frame 133, there are transverse positioning cylinders 1334 for adjusting the transverse position of the lens and longitudinal positioning cylinders 1333 for adjusting the longitudinal position of the lens, so that the robotic arm can grasp the lens from a fixed point. A rubber protective layer is provided on the upper surface of the support frame 1335 to prevent scratches on the lens.

[0034] Specifically, at the front corner of the lifting frame 133, a first positioning part 1331 and a second positioning part 1332 are respectively provided. The front end and left side of the first positioning part 1331 are respectively provided with a protective block 1337. The front end of the second positioning part 1332 is provided with a protective block 1337. A transverse positioning cylinder 1334 fixedly installed on the lifting frame 133 is provided on the right side of the second positioning part 1332. The piston rod of the transverse positioning cylinder 1334 extends to the right. A longitudinal positioning cylinder 1333 fixedly installed on the rear side of the lifting frame 133 is provided. There are two longitudinal positioning cylinders 1333, and their piston rods extend to the rear. Push plates 1336 are provided at the ends of the piston rods of the transverse positioning cylinder 1334 and the longitudinal positioning cylinder 1333. Protective blocks 1337 are provided on the push plates 1336. When the piston rods of the transverse positioning cylinder 1334 and the longitudinal positioning cylinder 1333 retract, they also retract. The protective blocks 1337 push the lens to the left and forward, respectively. The first positioning part 1331 and the second positioning part 1332 limit the front end and left end of the lens. Under the pushing action of the transverse and longitudinal positioning cylinders, the lens is fixed in the lifting frame 133. The protective blocks 1337 are circular rubber protective blocks to prevent the lens from being bumped when adjusting its position.

[0035] In the conveyor 12, a positioning sensor 122 is provided in the front half of the positioning mechanism 13. The positioning sensor 122 is set vertically upward and electrically connected to the controller. When the positioning sensor 122 detects the lens, the controller drives the piston rod of the lifting cylinder 132 to extend and lift the lifting frame 133. The lifting frame 133 lifts the lens from the conveyor 12. Then, the piston rods of the transverse positioning cylinder 1334 and the longitudinal positioning cylinder 1333 retract to adjust the position of the lens and fix the lens in the positioning mechanism 13.

[0036] Specifically, the feeding sensor 1137, the positioning sensor 122, and the positioning sensor 121 are infrared sensors.

[0037] In use, the operator places the lens in the flipping frame 113, steps on the foot switch, and the loading sensor 1137 detects whether a lens is placed at the current position. If a lens is detected, the controller controls the piston rod of the flipping cylinder 112 to retract and transfer the lens to the conveyor 12. The lens is then transported along the conveyor 12 to the positioning mechanism 13. After the positioning sensor 122 detects the lens, the controller controls the lifting cylinder 132 to raise the lifting frame 133 and lift the lens. Subsequently, the piston rods of the horizontal positioning cylinder 1334 and the vertical positioning cylinder 1333 retract to adjust the position of the lens and fix it, thus realizing the fixed-point loading of the heliostat lens.

[0038] 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.
