Abstract
Description
Technical Field
[0001] This utility model relates to the field of silicon core transfer technology, and in particular to an automated silicon core storage mechanism. Background Technology
[0002] In the field of solar photovoltaic technology, the manufacture of polycrystalline silicon using the modified Siemens process increasingly employs round silicon core technology. Currently, the traditional method requires two people to work together. Two people stand at opposite ends of the operating area, simultaneously lifting the silicon cores and transferring them into a basket. After placing one layer (16 cores), a divider is taken from each end and inserted into the basket, and then the silicon cores are placed in sequence. This manual method of loading silicon cores into baskets and placing dividers has many drawbacks.
[0003] Slow operating pace: When manually picking up and placing the card strips, each one needs to be picked up, aligned, and placed one by one, resulting in intermittent pauses in the action. Compared to the continuous and high-speed operation of automated equipment, manual operation is difficult to keep up with the mechanical rhythm of silicon core placement. After each layer of silicon cores is placed, it is necessary to wait for manual completion of the card strip laying, which limits the overall production line turnover speed, reduces production efficiency, and slows down capacity output.
[0004] High labor costs: Dedicated workers need to be stationed continuously, increasing the investment in manpower. Moreover, workers are prone to fatigue due to repetitive and simple actions over long periods of time. To maintain efficiency, it may be necessary to increase shift work, further increasing labor costs. Additional resource consumption will also occur due to personnel management, training, and other aspects.
[0005] Poor positioning accuracy of the clamping strip: Manual operation relies on experience and feel, making it difficult to ensure that the clamping strip is accurately embedded in the gap between the silicon cores and that the force is evenly distributed every time. Misalignment of the clamping strip will cause the silicon cores to be not firmly fixed. During subsequent handling and processing, the silicon cores are prone to collision and displacement, affecting the neatness of the frame assembly, and may even cause scratches and damage to the surface of the silicon cores, reducing product quality.

[0068] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0069] like Figure 1 , Figure 2 and Figure 7 As shown, this utility model embodiment provides an automated silicon chip storage mechanism, including: a lateral moving mechanism 1, a lifting mechanism 2, a mounting assembly 3, a clamping drive 4, a fixing plate 5, and a clamping plate 6. The lateral moving mechanism 1 is installed at both ends of the silicon chip gripper 9, with the movable ends of the two lateral moving mechanisms 1 facing away from each other. The lifting mechanism 2 is installed at the movable end of the lateral moving mechanism 1, and its movable end is vertically downward after installation. The mounting assembly 3 is installed on the movable end of the lifting mechanism 2. The clamping drive 4 is installed at the end of the mounting assembly 3 away from the silicon chip gripper 9, and its movable end is horizontal after installation. The fixing plate 5 is installed at the end of the mounting assembly 3 away from the silicon chip gripper 9 or on the movable end of the clamping drive 4. The clamping plate 6 is installed on the movable end of the clamping drive 4, and a clamping area for clamping the silicon chip support strip 8 is formed between the fixing plate 5 and the clamping plate 6.
[0070] In use, the silicon core gripper 9 is moved to move above the flower basket 7. Then, the lifting mechanism 2 is moved to the designated position on the flower basket 7 by the lateral moving mechanism 1. The lifting mechanism 2 then descends to the designated position, and finally, the clamping drive 4 drives the fixing plate 5 and clamping plate 6 to clamp the silicon core support bar 8. After clamping, the lifting mechanism 2 rises, so that the silicon core support bar 8 is completely detached from the flower basket 7. Immediately afterwards, the lateral moving mechanism 1 adjusts its position so that the silicon core support bar 8 is located in the middle of the flower basket 7. Then, the lifting mechanism 2 is controlled to smoothly lower the silicon core support bar 8, accurately placing the silicon core support bar 8 into the flower basket 7.
[0071] After the silicon core support strip 8 is placed, the silicon core gripper 9 picks up the silicon core and places it on top of the silicon core support strip 8. Then the above action is repeated to complete the transfer and placement of the silicon core to the silicon core support strip 8. The operation is repeated continuously to complete the transfer and placement of the silicon core.
[0072] Using this automatic gripping device to grip and place the silicon core support strip 8 can significantly improve the silicon core transfer efficiency.
[0073] Mechanized operation offers high repeatability and precision, avoiding the impact of human factors on the position of the silicon core support strip 8 (positional deviation may lead to insecure fixing of the silicon core, causing it to easily collide and shift during subsequent handling and processing, affecting the neatness of the frame assembly, and may even cause scratches and damage to the silicon core surface, reducing product quality).
[0074] In one embodiment, such as Figure 1 , Figure 2 and Figure 7 As shown, the lateral movement mechanism 1 includes a lateral drive component 11 and a mounting component 12. The lateral drive component 11 is mounted on the top of the silicon core gripper 9. The mounting component 12 is mounted on the movable end of the lateral drive component 11, and the lifting mechanism 2 is mounted on the mounting component 12.
[0075] In order to facilitate the adjustment of the position of the lifting mechanism 2 during use, a lateral drive component 11 is provided on the silicon core gripper 9. The lateral drive component 11 can be a cylinder, hydraulic cylinder, electric telescopic rod, linear motor or other drive mechanism that can realize linear motion.
[0076] Mounting component 12 is provided to facilitate the installation of lifting mechanism 2.
[0077] It should be noted that the lifting mechanism 2 can be a cylinder, hydraulic cylinder, electric telescopic rod, linear motor or other drive mechanism that can achieve linear motion.
[0078] In one embodiment, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, to facilitate the installation of the clamping drive component and to facilitate the movement of the clamping drive component in driving the fixed plate 5 and clamping plate 6, the mounting assembly 3 includes: a mounting plate 31, a connecting plate 32, and a fixing rod 33. The mounting plate 31 is installed at the movable end of the lifting mechanism 2. The connecting plates 32 are installed at both ends of the mounting plate 31, and after installation, the ends of the two connecting plates 32 away from the mounting plate 31 are inclined relative to each other. The fixing rod 33 is installed on the inclined outer wall of the connecting plate 32. After installation, the ends of the two fixing rods 33 away from their connection with the connecting plate 32 are set opposite to each other, and the clamping drive component 4 is installed on the fixing rod 33.
[0079] In one embodiment, in order to facilitate the clamping of the silicon core support bar 8, the clamping drive 4 is a clamping cylinder, and the fixing plate 5 and the clamping plate 6 are respectively mounted on the claw of the clamping cylinder.
[0080] In one embodiment, such as Figure 4As shown, in order to facilitate the clamping of the silicon core support strip 8, clamping openings are provided on the side walls of the fixing plate 5 and the clamping plate 6 that are arranged opposite to each other, and the clamping area is formed between the two clamping openings.
[0081] In one embodiment, such as Figure 1 , Figure 5 and Figure 7 As shown, the automated silicon core storage mechanism further includes a basket 7 for storing silicon cores. The basket 7 includes two positioning rods 71, multiple U-shaped structural members 72, and end plates 73. Silicon core support strips 8 are snapped onto the structural members 72 along the length of the positioning rods 71. End plates 73 are provided at both ends of the positioning rods 71. Both ends of the basket 7 have placement areas for placing the silicon core support strips 8.
[0082] To facilitate the transfer of silicon cores, a basket 7 is provided, with spare silicon core support bars 8 at both ends along its length. When placing the silicon cores, the clamping drive 4 first moves the fixing plate 5 and clamping plate 6 to grasp the silicon core support bars 8 placed at both ends of the basket 7. After grasping, the lifting mechanism 2 rises, completely detaching the silicon core support bars 8 from the basket 7. Next, the lateral movement mechanism 1 adjusts the position so that the silicon core support bars 8 are in the middle of the basket 7. Then, the lifting mechanism 2 is controlled to smoothly lower the silicon core support bars 8, accurately placing them into the basket 7. During the lowering process, the silicon core support bars 8 are engaged with the corresponding structural components 72.
[0083] In one embodiment, such as Figure 1 , Figure 5 mix Figure 6 As shown, the silicon core support bar 8 includes: an isolation rod 81 and a buffer block 82. Buffer blocks 82 are provided at both ends of the isolation rod 81. The buffer block 82 is provided with a snap-fit groove 83 that matches the structural component 72. When the silicon core support bar 8 is clamped, the clamping drive component 4 drives the fixing plate 5 and the clamping plate 6 to clamp the buffer block 82.
[0084] To prevent the silicon core support bar 8 from moving within the basket 7, a snap-fit groove 83 matching the structural component 72 is provided on the buffer block 82.
[0085] In one embodiment, such as Figure 6 As shown, in order to prevent the silicon core from shifting when placed on the silicon core support bar 8, a limiting groove 84 is provided on the top of the isolation rod 81 to match the number of silicon cores gripped by the silicon core gripper 9.
[0086] In one embodiment, such as Figure 2As shown, the silicon core gripper 9 includes a fixing member 91 and an adsorption assembly 92. The fixing member 91 is slidably connected to the truss. The adsorption assembly 92 is installed at the end of the fixing member 91 facing the ground.
[0087] The controller moves the silicon core gripper 9 on the truss to the top of the basket 7. Then, the gripper 9 is lowered by a lifting cylinder, extending into the basket 7. The clamping drive 4 then moves the fixing plate 5 and clamping plate 6 to grip the silicon core support bar 8. The lifting mechanism 2 and the lifting cylinder then rise, completely detaching the silicon core support bar 8 from the basket 7. It then moves to a designated position, where the lifting cylinder moves the gripper 9, causing the silicon core support bar 8 to engage with the corresponding structural component 72. The gripper 9 moves to the silicon core storage platform, then descends and adsorbs the silicon core through the adsorption component 92. After adsorption, it moves to the top of the basket 7 and places it inside the silicon core support bar 8.
[0088] More specifically, the adsorption assembly 92 includes: a mounting rod 921, a suction cup 922, and an adsorption pump 923. One end of the mounting rod 921 is mounted on a fixing member 91. The suction cup 922 is mounted on the other end of the mounting rod 921. The adsorption pump 923 is mounted on the mounting rod 921 and is in communication with the suction cup 922.
[0089] When the suction cup 922 comes into contact with the silicon core, the adsorption pump 923 operates to generate negative pressure, adsorbing the silicon core onto the suction cup 922. Then, the silicon core gripper 9 is moved to the top of the basket 7, and the silicon core gripper 9 is lowered to a certain height, placing the silicon core on the silicon core support strip 8 inside the basket 7.
[0090] Subsequently, the silicon core gripper 9 rises. When its height exceeds that of the basket 7, the lateral movement component moves, causing the two lifting mechanisms 2 to move outward. Then, the clamping drive component 4 drives the fixing plate 5 and clamping plate 6 to clamp the silicon core support strip 8 and place it in the middle of the basket 7. This cycle is repeated to complete the task of transferring and placing the silicon core.
[0091] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
