In existing feeding equipment, the heliostat is prone to deviation during transportation. When using a robotic arm to grasp it, it is difficult to accurately grasp the backboard of the heliostat, and there is a lack of a feeding device that can convey the heliostat to a fixed point.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. The following describes the specific implementation of the present utility model in detail in conjunction with specific embodiments.

[0028] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0029] Such as Figures 1 - 6As shown in the figure, a material loading rack for the backboard of a heliostat includes a rack body 4. A conveyor belt 1 is arranged on the rack body 4. Along the movement direction of the conveyor belt 1, a loading auxiliary mechanism 2 is arranged at the entrance of the rack body 4 to position the loading position of the backboard 6 of the heliostat. A positioning mechanism 3 is arranged at the exit of the rack body 4. The positioning mechanism 3 adjusts and fixes the position of the backboard 6 of the heliostat so that the robotic arm can accurately grip the backboard 6 of the heliostat from the exit position of the backboard 6 of the heliostat.

[0030] As Figure 1 , Figure 2 and Figure 4 shown in the figure, conveyor belts 1 are installed on both sides of the rack body 4. The conveyor belt 1 is a chain conveyor belt 1. The conveyor belt 1 is driven by a motor 11, and the motor 11 is electrically connected to a controller. A first fixing plate 41 is arranged at the entrance of the rack body 4. First angle codes 44 are arranged on both sides of the first fixing plate 41. One side of the first angle code 44 is fixedly connected to the first fixing plate 41, and the other side is fixedly connected to the rack body 4 to fixedly install the first fixing plate 41 in the rack body 4. The loading auxiliary mechanism 2 is installed in the first fixing plate 41. The loading auxiliary mechanism 2 includes a lifting cylinder 21 and a positioning disk 22 installed on the piston rod of the lifting cylinder 21. The side wall of the lifting cylinder 21 is installed on the first fixing plate 41, and the piston rod of the lifting cylinder 21 is vertically upward. The positioning disk 22 includes a positioning plate 23 and positioning frames 24 arranged on both sides of the positioning plate 23. Grooves are arranged in the positioning frames 24. An installation plate 61 is arranged at the center position of the backboard 6 of the heliostat. The shape of the groove matches the shape of the installation plate 61 of the backboard 6 of the heliostat. The backboard 6 of the heliostat can be placed on the positioning disk 22, and the installation plate 61 is clamped at the groove. When the piston rod of the lifting cylinder 21 extends, the height of the positioning disk 22 is higher than the height of the conveyor belt 1. When the piston rod of the lifting cylinder 21 contracts, the height of the positioning disk 22 is lower than the height of the conveyor belt 1, and the backboard 6 of the heliostat falls onto the conveyor belt 1.

[0031] As Figure 1As shown in the figure, a first sensor 47 is provided beside the conveyor belt 1 on one side of the frame 4. When the heliostat backplane 6 is located on the positioning disc 22, the first sensor 47 is arranged at the loading auxiliary mechanism 2, below the installation position of the heliostat backplane 6. When the heliostat backplane 6 falls onto the conveyor belt, the first sensor 47 can detect whether the heliostat backplane 6 is installed in place, and the first sensor 47 is electrically connected to the controller. On the outside of the frame 4, a foot switch 5 is provided, and the foot switch 5 is used to start the loading auxiliary mechanism 2. After the staff places the heliostat backplane 6 stably, they leave the equipment and activate the foot switch 5, and the piston rod of the lifting cylinder 21 contracts. When the heliostat backplane 6 is placed in place and falls onto the conveyor belt 1, after the first sensor 47 detects that the heliostat backplane 6 is in place, the controller starts the conveyor belt 1 to transport the heliostat backplane 6 to the end of the frame 4; when the first sensor 47 does not detect the heliostat backplane 6, an alarm is issued to inform the staff. Using this loading auxiliary mechanism 2 ensures that the heliostat backplane 6 starts to be conveyed from a fixed point, guaranteeing the accuracy of the movement of the heliostat backplane 6. The controller starts the motor 11 to drive the conveyor belt 1 to move a certain distance, transporting the heliostat backplane 6 placed on the conveyor belt 1 above the positioning mechanism 3. After the heliostat backplane 6 leaves, the loading auxiliary mechanism 2 returns to its original position.

[0032] When the heliostat backplane 6 moves on the conveyor belt 1, after the conveyor belt 1 stops, the heliostat backplane 6 may shift due to inertia, resulting in a deviation of the position of the heliostat backplane 6 from the preset position. When using the robotic arm to grasp the heliostat backplane 6, it is impossible to accurately grasp the heliostat backplane 6. Such as Figure 3 and Figure 5As shown in the figure, in order to improve the accuracy of grasping the back plate 6 of the heliostat, a positioning mechanism 3 is designed at the end of the frame 4 to adjust and fix the position of the back plate 6 of the heliostat. A second fixing plate 42 and a third fixing plate 43 are arranged at the outlet of the frame 4. Second angle codes 45 and third angle codes 46 are respectively arranged on both sides of the second fixing plate 42 and the third fixing plate 43. One side of the second angle code 45 is fixedly connected to the second fixing plate 42, and the other side is fixedly connected to the frame 4. One side of the third angle code 46 is fixedly connected to the third fixing plate 43, and the other side is fixedly connected to the frame 4, so as to fixedly install the second fixing plate 42 and the third fixing plate 43 in the frame 4. The positioning mechanism 3 is arranged between the second fixing plate 42 and the third fixing plate 43, and includes a cylinder fixing plate 31 and four side posture cylinders 32 installed on the cylinder fixing plate 31. On both sides of the cylinder fixing plate 31, it is fixedly connected to the side walls of the second fixing plate 42 and the third fixing plate 43 through fourth angle codes 33. A fixing frame 34 is installed on the cylinder fixing plate 31, a connecting plate 35 is installed on the fixing frame 34, and the side posture cylinders 32 are installed on the connecting plate 35. The side posture cylinders 32 form a 45-degree angle with the second fixing plate 42 or the third fixing plate 43 in the horizontal direction. A rotating frame 325 is arranged on the rotating shaft 324 of the side posture cylinder 32. The rotating frame 325 rotates around the rotating shaft 324 of the side posture cylinder 32. A convex block 326 is arranged at the front end of the rotating frame 325. The convex block 326 abuts against the corner position of the mounting plate 61 of the back plate 6 of the heliostat. Two side posture cylinders 32 on the same side clamp one mounting plate 61, and the four side posture cylinders 32 jointly adjust and fix the position of the back plate 6 of the heliostat.

[0033] The side posture cylinder 32 can be a hinge type side posture cylinder or a rack type side posture cylinder. Both the hinge type side posture cylinder and the rack type side posture cylinder are existing technologies. In this embodiment, the rack type side posture cylinder is used to elaborate on this technical solution. As Figure 6 shown, the side posture cylinder 32 includes a cylinder body of the cylinder and a housing 321 arranged above the cylinder body. The housing 321 protects the structure of the side posture cylinder 32. A rack 322 is arranged at the upper part of the piston rod. A rotating shaft 324 rotatably connected to the housing 321 is arranged on one side of the rack 322. A gear 323 is arranged on the rotating shaft 324. The gear 323 is meshed with the rack 322. The rotating frame 325 is fixedly connected to both ends of the rotating shaft 324. A convex block 326 is arranged at the front end of the rotating frame 325. The rotation of the gear 323 is driven by the cylinder piston rod, so that the rotating frame 325 rotates around the rotating shaft 324, and the convex block 326 abuts against the corner position of the mounting plate 61 of the back plate 6 of the heliostat.

[0034] As Figure 1As shown in the figure, on one side of the frame body 4, at the path position of the heliostat backplane 6, between the positioning mechanism 3 and the feeding auxiliary mechanism 2, a second sensor 48 is provided. The second sensor 48 detects the passing condition of the heliostat backplane 6 to check whether the heliostat backplane 6 is transported to the positioning mechanism 3 by the conveyor belt. A third sensor 49 is provided at the end of the frame body 4. When the heliostat backplane 6 is clamped by the positioning mechanism 3, the third sensor 49 is arranged below the heliostat backplane 6 to detect whether the heliostat backplane 6 is in place. The second sensor 48 and the third sensor 49 are electrically connected to the controller. According to the detection results of the second sensor 48 and the third sensor 49, the robotic arm determines whether to grasp the heliostat backplane 6. When the second sensor 48 detects that the heliostat backplane 6 has passed and the third sensor 49 detects that the heliostat backplane 6 is in place, it means that the heliostat backplane 6 is accurately transported without error during the transportation by the conveyor belt 1, and the robotic arm can grasp the heliostat backplane 6 and transport it to the next working process. When either the second sensor 48 or the third sensor 49 does not detect the heliostat backplane 6, it may indicate that the heliostat backplane 6 has shifted during transportation or the staff has directly carried the heliostat backplane 6 to the positioning mechanism 3 without using the conveyor belt 1. The controller sends a signal to inform the staff, and the robotic arm does not grasp the heliostat backplane 6. The combined detection of the second sensor 48 and the third sensor 49 is used to prevent the robotic arm from forcibly grasping the heliostat backplane 6 in the wrong position, which may further damage the heliostat backplane 6 or the robotic arm, and can also prevent personal injury to the staff when the robotic arm grasps the heliostat backplane 6, avoiding the occurrence of production risks.

[0035] During use, the staff places the heliostat backplane 6 in the positioning disk 22, away from the feeding rack and starts the foot switch 5. The piston rod of the lifting cylinder 21 descends, and the heliostat backplane 6 falls onto the conveyor belt 1. After the first sensor 47 detects the heliostat backplane 6, it sends a signal to the controller, and the controller starts the conveyor belt 1. The conveyor belt 1 runs for a certain distance to transport the heliostat backplane 6 to the end of the feeding rack. During the transportation process, it passes through the detection of the second sensor 48. After the heliostat is in place, the positioning mechanism 3 is started to adjust the position of the heliostat backplane 6 and clamp the heliostat backplane 6 to fix its position. The third sensor 49 detects whether the heliostat backplane 6 is in place. If it passes the detection of the second sensor 48 and the third sensor 49 and sends a signal that the heliostat backplane 6 can be grasped to the controller, the robotic arm grasps the heliostat backplane 6 and transports the heliostat backplane 6 to the next process.

[0036] The above are only the preferred embodiments of the present utility model, and do not impose other forms of limitation on the present utility model. Any person skilled in the relevant art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the protection scope of the technical solution of the present utility model.
