Description

Technical Field

[0001] This invention belongs to the field of secondary feeding of silicon material in photovoltaic silicon material preparation, and in particular relates to a re-feeding cylinder charging mechanism. Background Technology

[0002] The main method for preparing photovoltaic silicon materials is to load virgin silicon blocks into a quartz crucible, and then use a heating furnace to melt and recrystallize the silicon material into a solid state according to a certain process formula and technology to obtain silicon materials for photovoltaic power generation.

[0003] During the melting process, the virgin silicon material changes from solid to liquid, its volume decreases, and the gaps between the material blocks are eliminated. The crucible is filled with silicon material and melted. The liquid level of the silicon is much lower than the edge of the crucible opening. At this point, silicon material needs to be added to the crucible again to increase the amount of material in the crucible, increase production capacity, and improve production efficiency.

[0004] The secondary feeding process requires refilling the feeding cylinder, but the current method of refilling the cylinder is to manually use shovels and ladders to climb and load materials, which is inefficient and labor-intensive. Summary of the Invention

[0005] In view of this, the present invention aims to propose a refilling cylinder loading mechanism to solve the problems of high manual labor intensity, long loading time, and low production efficiency when loading the refilling cylinder during the secondary feeding of photovoltaic silicon material preparation.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] A refilling cylinder loading mechanism includes a locking mechanism, a frame, a docking telescopic cylinder mechanism, a refilling cylinder fixing frame assembly, a hopper mechanism, a dust removal system, an electrical control module, and a straightening mechanism;

[0008] A hopper mechanism is located above the frame, and a dust removal system is located above the hopper mechanism. The hopper mechanism is connected to a telescopic cylinder mechanism below it. A re-feeding cylinder fixing frame assembly is located below the telescopic cylinder mechanism and is fixedly connected to the machine frame. A locking mechanism is located at the bottom of the frame, an electrical control module is located on one side of the frame, and a straightening mechanism is installed on the locking mechanism.

[0009] The locking mechanism includes a frame, two first locking structures, two second locking structures, and two lifting mechanisms. The centering mechanism is located on one side of the frame, and a support frame is provided on the frame. One end of each of the two lifting structures is rotatably connected to the support frame. The other end of each of the two lifting structures is connected to a first locking structure, and the two second locking structures are mounted on the support frame. The second locking structures are mounted on the side away from the lifting structures.

[0010] Furthermore, the alignment mechanism includes two positioning frames and four first cylinders. The two positioning frames are installed on both sides of the frame, and the fixed ends of the two first cylinders are installed on one positioning frame. The output ends of the first cylinders are located inside the frame. The first positioning frames are connected to the machine frame, and the positioning adjustment range is designed according to the size of the trolley. When the feeding trolley enters the two positioning frames, the four first cylinders act simultaneously, controlling the movement of the output ends of the first cylinders to align the material trolley to the receiving position. The alignment mechanism can position the material trolley, improving the accuracy of material receiving. The alignment mechanism also aligns and clamps the trolley, preventing it from swaying left and right, which would affect the swaying of the refilling cylinder.

[0011] Furthermore, the first locking structure includes a first connecting plate, a second connecting plate, two second cylinders, a cylinder bracket, a third connecting plate, a T-shaped connecting plate, and a fourth connecting plate. The two second cylinders are mounted on the cylinder bracket. The first connecting plate is fixedly disposed at the end of each second cylinder and is disposed on the lifting structure. The output shaft of each second cylinder has a third connecting plate, on which a T-shaped connecting plate is fixedly connected. The fourth connecting plate is fixed to the first connecting plate. The T-shaped connecting plate has a through hole for the push rod of the trolley to pass through. The first locking assembly is fixed to the side of the support frame near the positioning mechanism. When it is necessary to lock the push rod of the trolley, the second cylinder drives the T-shaped connecting plate downwards, and the push rod is disposed in the through hole of the T-shaped connecting plate. When locking is not required, the second cylinder drives the T-shaped connecting plate upwards, and the push rod is unrestricted.

[0012] Furthermore, the second locking structure includes a third cylinder, a locking rod, and a rotating shaft. The fixed end of the third cylinder is fixedly mounted on the support frame, the rotating shaft is fixedly mounted on the support frame, the middle part of the locking rod is rotatably mounted on the support frame, and one end of the locking rod is fixedly connected to the output shaft of the third cylinder. The two second locking structures are arranged on both sides of the support frame.

[0013] Furthermore, an L-shaped gripper is provided below the end of the locking rod away from the rotating shaft. The third cylinder drives the locking rod to move up and down, and the third cylinder drives the locking rod to rotate. When the output shaft of the third cylinder moves upward, the L-shaped gripper moves downward and grips the bottom of the trolley. When the output shaft of the third cylinder moves downward, the L-shaped gripper moves upward and releases.

[0014] The lifting structure includes a lifting cylinder. A rotating plate is fixedly provided at the end of the lifting cylinder. A rotating hole is provided on the rotating plate. The fixed end of the lifting cylinder is hinged to the support frame; the output end of the lifting cylinder is fixedly connected with a first connecting plate. One end of the lifting cylinder is rotatably connected, which can avoid leaving a margin when the lifting cylinder pushes the trolley. The car locking mechanism tightly locks the trolley to prevent it from moving forward and backward. The entire car locking mechanism realizes the accurate docking of the refeeding cylinder and the telescopic cylinder of the feeding mechanism, preventing material scattering and blocking. The lifting structure can slowly lift the inclined refeeding cylinder and ensure that the cylinder forms a 90° angle with the ground.

[0015] Furthermore, the docking telescopic cylinder mechanism includes a power component, a feeding component, a telescopic cylinder component, and a material bucket docking mechanism; the feeding component is fixedly arranged above the telescopic cylinder component, the power component is arranged on one side of the telescopic cylinder component, and the material bucket docking structure is arranged at the bottom of the telescopic cylinder component. The telescopic cylinder component includes a fixed cylinder and a telescopic cylinder. The telescopic cylinder is slidably installed on the fixed cylinder, and the fixed cylinder is fixedly arranged at the bottom of the feeding component. This device drives the telescopic cylinder and the material bucket docking structure through the power component. The material bucket docking structure directly realizes seamless docking with the material bucket to be filled. After the filling is completed, the power component drives the telescopic cylinder and the material bucket docking component back to the original position, improving the stability of the equipment, avoiding waste phenomena such as material leakage, and reducing the production cost.

[0016] Furthermore, the telescopic cylinder is sleeved on the fixed cylinder. The feeding component includes a feeding bucket. A feeding port is provided at the top of the feeding bucket, a discharge port is provided at the bottom of the feeding bucket, and the bottom of the feeding bucket is connected to the fixed cylinder.

[0017] Furthermore, an installation frame is provided on the feeding pipe. The feeding plate is fixed to the support frame of the equipment through the installation frame. A blockage detection device is provided on the feeding component. The blockage detection device uses existing equipment. The blockage detection device is a light curtain, and the model of the light curtain is: STD-Sinso-light curtain-HB-NA306-B-2. Through the light curtain, it can be judged whether the material in the feeding component is blocked. A light curtain through hole corresponding to the light curtain is provided on the fixed cylinder. During the filling process, when the material accumulates and blocks, the detection mechanism alarms and stops filling to prevent the material from spilling.

[0018] Furthermore, the power component includes a docking cylinder, a fifth connecting plate, and a mounting plate. The fixed end of the docking cylinder is fixed on the mounting plate, and the mounting plate is fixed on the equipment or the support frame. Two fifth connecting plates are provided at the output end of the docking cylinder, and the fifth connecting plates are fixedly connected with the telescopic rod. A push rod is provided at the bottom of the fifth connecting plate, and the push rod is fixedly connected with the material bucket docking component.

[0019] Furthermore, the docking cylinder is equipped with a protective component, which is a protective sleeve fixed to the mounting plate. The bottom of the protective sleeve has an opening. This device, by incorporating the protective component, can prevent dust from affecting the docking cylinder, thus extending its service life. The material barrel docking assembly includes a docking plate and a discharge barrel. One end of the discharge barrel is connected to a fixed barrel, and the bottom of the discharge barrel is fixedly connected to the docking plate. The discharge barrel docks with the transport cylinder of the trolley.

[0020] The docking plate is installed on the frame via the re-throwing cylinder fixing frame assembly.

[0021] Furthermore, the dust removal system includes several dustproof plates, which are installed on the upper part and around the hopper mechanism. This device can prevent dust from entering the hopper mechanism by installing dustproof plates.

[0022] The hopper mechanism includes a hopper and a material discharge speed control component, wherein the material discharge speed control component is disposed above the hopper;

[0023] The material dropping speed control mechanism includes a push plate, a material dropping speed control cylinder, and a material dropping connecting rod.

[0024] The hopper is provided with a rotating hole at the top, and a push plate is rotatably mounted on the hopper.

[0025] The bottom of the hopper is aligned with the top of the feed hopper.

[0026] The hopper can hold silicon material, improving the robot's material handling efficiency and enabling the mixing of different types of silicon material. The material discharge speed control mechanism ensures the protection of the silicon material against the inner wall of the refilling cylinder. Simultaneously, it adjusts the opening and closing size of the material gate and the opening and closing cycle time according to the material discharge volume to regulate the discharge speed and prevent blockage during silicon material descent. The material discharge speed control mechanism within the hopper adjusts the opening and closing size of the material gate and the cycle time based on the amount of silicon material in the hopper, controlling the silicon material to be slowly loaded into the refilling cylinder. This material discharge speed control mechanism prevents the risk of blockage or jamming during loading.

[0027] The refilling cylinder fixing frame assembly includes a refilling cylinder frame, a fourth cylinder, and an L-shaped fixing rod. The refilling cylinder frame is fixed to the machine frame, and the fourth cylinder is mounted on the refilling cylinder frame. The output end of the fourth cylinder is connected to the vertical end of the L-shaped fixing rod. When the cylinder reaches the bottom of the docking telescopic cylinder mechanism, the output rod of the fourth cylinder moves backward, controlling the L-shaped fixing rod to fix the cylinder. After the filling is completed, the output rod of the fourth cylinder moves forward, releasing the cylinder.

[0028] Furthermore, the electrical control module is electrically connected to the lifting mechanism, the first cylinder, the second cylinder, the third cylinder, the fourth cylinder, the lifting cylinder, the material blockage detection device, the docking cylinder, and the material dropping speed control cylinder. The electrical control module adopts existing PLC technology.

[0029] Compared with the prior art, the refillable cylinder loading mechanism of the present invention has the following advantages:

[0030] 1. This device uses a centering mechanism to center and clamp the trolley, preventing it from swaying left and right and affecting the movement of the re-feeding cylinder. A locking mechanism firmly locks the trolley to prevent forward and backward movement. This locking mechanism ensures accurate docking of the re-feeding cylinder with the telescopic cylinder of the loading mechanism, preventing spillage and blockage. The lifting structure can slowly elevate the tilted re-feeding cylinder, ensuring it forms a 90° angle with the ground. This device improves production efficiency, reduces worker fatigue, and shortens loading time.

[0031] 2. This device uses a power unit to drive the telescopic barrel and the material barrel docking structure. The material barrel docking structure directly and seamlessly connects with the material barrel to be filled. After filling is completed, the power unit drives the telescopic barrel and the material barrel docking structure back to their original positions, which improves the stability of the equipment, avoids waste such as leakage, and reduces production costs.

[0032] 3. The material feeding speed control mechanism in the hopper adjusts the opening and closing size of the material gate and the cycle time according to the amount of silicon material in the hopper to control the silicon material to be slowly loaded into the re-feeding cylinder. The material feeding speed control mechanism can prevent the risk of material blockage and jamming during loading. Attached Figure Description

[0054] First, the refill trolley is manually or by AGV pulled into the locking area. The locking mechanism 1 performs the locking action, and the refill trolley is locked after being aligned. When the filling trolley enters the two positioning frames 11, the four first cylinders 12 are activated simultaneously to control the output end of the first cylinder 12 to move and align the material barrel trolley to the receiving position, locking the trolley. When the trolley is placed in the receiving position, the second cylinder 28 is controlled to move downward and the third cylinder 20 is controlled to move upward to lock the trolley, ensuring that the material barrel rises and falls smoothly before and after filling. Then, the lifting cylinder 24 is controlled to push the trolley to the docking position of the discharge port 33. The material barrel is placed vertically on the trolley. After filling is completed, the refill barrel is prevented from tilting. After all the refilling cylinders have docked with the telescopic docking cylinder, the front-end robot performs the material handling and unloading action, pouring the silicon material into the hopper mechanism 6. The material discharge speed control mechanism in the hopper mechanism 6 adjusts the opening and closing size of the material gate and the cycle time according to the amount of silicon material in the hopper 42 to control the silicon material to be slowly loaded into the refilling cylinder. The material discharge speed control mechanism can prevent the risk of material blockage or jamming during loading. When the material cylinder reaches the bottom of the telescopic docking cylinder mechanism 4, the output rod of the fourth cylinder 47 moves backward, controlling the L-shaped fixing rod 48 to fix the material cylinder. After the required amount of silicon material is loaded into the refilling cylinder, the output rod of the fourth cylinder 47 moves forward to release the material cylinder. After the required amount of silicon material is loaded into the refilling cylinder, the refilling cylinder fixing mechanism is released. After the filling is completed, the output end of the lifting cylinder 24 moves downward, slowly lowering the material cylinder to the initial position, until the entire action is completed. After all the cylinders on the refilling trolley are filled and reset, the locking mechanism 1 automatically unlocks, the refilling trolley is pulled out of the locking area, and the material is loaded in a cyclical manner.
