Abstract
Description
Technical Field
[0001] This utility model relates to the field of crystal rod processing equipment, and in particular to a silicon rod feeding device. Background Technology
[0002] In the design of silicon ingot feeding structures, existing processing equipment mostly adopts a conveyor belt feeding method. A transfer device transfers the silicon ingot onto the conveyor belt, which then transports the ingot to be processed to the designated position. To detect the size of the silicon ingot during feeding, through-beam sensors are usually installed at the feeding end of the conveyor belt. The size of the silicon ingot is calculated based on the change in the sensing time of the through-beam sensors before and after the ingot passes through, as well as the conveyor belt speed. However, this method can only calculate the size when the silicon ingot passes through in one direction. In some operating conditions, when the silicon ingot needs to move bidirectionally on the feeding structure to adjust its feeding position, the aforementioned through-beam sensors will sense multiple times, making it impossible to accurately calculate the size of the silicon ingot, which affects subsequent processing. Utility Model Content

[0020] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0021] Please refer to Figures 1 to 3A silicon rod feeding device includes a feeding rack 1 and a feeding mechanism. The feeding rack 1 is provided with a slide for placing silicon rods. The feeding mechanism includes a feeding component and a pull rope sensor 7. The feeding component moves along the length of the slide and drives the silicon rod to move. The fixed end of the pull rope sensor 7 is connected to the feeding rack 1, and the movable end of the pull rope sensor 7 is connected to the feeding component.
[0022] As can be seen from the above description, the beneficial effects of this utility model are: the silicon rod is transferred to the designated feeding position by moving the feeding component along the slide, and the length of the silicon rod is calculated by the pull rope sensor 7 during the movement of the silicon rod.
[0023] Specifically, firstly, the distance between the fixed end of the pull rope sensor 7 and the end of the silicon rod when it moves to the designated feeding position (one end of the pull rope sensor 7) is determined, which is the first distance 10. Typically, the designated feeding position is a fixed position, so the first distance 10 is a fixed distance. Then, the distance between the fixed end of the pull rope sensor 7 and the initial position of the feeding assembly is determined, which is the second distance 11. Similarly, the second distance 11 is a fixed distance. After the silicon rod moves from the feeding assembly to the designated feeding position, due to the displacement of the feeding assembly, the movable end of the pull rope sensor 7 moves to obtain the moving distance of the pull rope sensor 7, i.e., the third distance 12. Therefore, the final length of the silicon rod is the sum of the first distance 10 - the second distance 11 - the third distance 12.
[0024] Furthermore, the feeding mechanism also includes a blocking mechanism 13, which is located at the feeding end of the slide and can be raised and lowered.
[0025] As described above, the blocking mechanism 13 is used to limit the other end of the silicon rod. During feeding, the silicon rod enters from the feeding end of the slide, and is then pulled by the feeding component until the entire silicon rod enters the slide. Then, the blocking mechanism 13 is raised and protrudes from the slide, and the feeding component pushes the silicon rod toward the blocking mechanism 13, thus achieving feeding limit at both ends of the silicon rod and placing it in the designated feeding position.
[0026] Furthermore, the feeding mechanism also includes a first sensor 4, which is electrically connected to the blocking mechanism 13. The first sensor 4 is used to detect the presence of silicon rods at the feeding end of the slide.
[0027] As can be seen from the above description, the setting of detecting the presence status of the silicon rod at the feeding end of the slide by the first sensor 4 can quickly identify the silicon rod after the feeding component pulls the entire silicon rod onto the slide and raise the blocking mechanism 13 to block and limit the silicon rod at one end.
[0028] Furthermore, the feeding end of the slide is open and equipped with a guide wheel.
[0029] As described above, when feeding through the slide, the silicon rod can be pushed in through its feeding end and, with the help of the guide wheel, ensure that the silicon rod moves smoothly within the slide, reducing wear.
[0030] Furthermore, it also includes a silicon rod transfer device for transferring silicon rods onto the slide of the loading rack 1.
[0031] As described above, the silicon rod is fed onto the slide by the silicon rod transfer device.
[0032] Furthermore, the silicon rod transfer device is an AGV (Automated Guided Vehicle).
[0033] As described above, silicon rods are transferred using AGV trolleys. The AGV trolleys can adjust their movement according to the working conditions and can push the silicon rods as they are fed onto the slide to assist the feeding components in pulling the silicon rods.
[0034] Furthermore, the feeding mechanism also includes a second sensor 5, which is located at the feeding end of the slide. The second sensor 5 cooperates with the silicon rod transfer device to determine the transfer of the silicon rod transfer device into place.
[0035] As described above, the cooperation between the second sensor 5 and the silicon rod transfer device ensures that the silicon rod transfer device transfers the silicon rod at the correct feeding position on the slide.
[0036] Furthermore, the feeding mechanism also includes a third sensor 6, which is located on the slide rail and is used to detect the presence status of the silicon rod on the slide rail. The third sensor 6 is electrically connected to the silicon rod transfer device.
[0037] As described above, by detecting the presence of silicon rods on the slide rail by the third sensor 6, when there are no silicon rods on the slide rail, it can identify and provide feedback to the silicon rod transfer device to transfer the silicon rods, thereby realizing automated silicon rod transfer and feeding.
[0038] Furthermore, it also includes a tilting cylinder 9 and a fixed frame 8, the fixed frame 8 being rotatably connected to the feeding frame 1, the fixed end of the tilting cylinder 9 being located on the fixed frame 8, and the movable end of the tilting cylinder 9 being located on the feeding frame 1.
[0039] As can be seen from the above description, by setting up the flipping cylinder 9 and the fixing frame 8, the feeding rack 1 can be flipped relative to the fixing frame 8 to adjust the position of the silicon rod, which is convenient for subsequent processes to grasp.
[0040] Furthermore, the third sensor 6 includes an oblique beam sensor 61 and a sensing element 62, which are respectively disposed at both ends of the slide and located on different sides of the slide.
[0041] As can be seen from the above description, by setting the oblique-emitting sensor 61 and the sensing plate 62 on the slide, the sensing range of the two can cover the entire slide, and the presence status of the silicon rod on the slide can be accurately identified.
[0042] Example 1:
[0043] like Figures 1 to 3 As shown, a silicon rod feeding device includes a feeding rack 1, a feeding mechanism, a blocking mechanism 13, and a silicon rod transfer device. The feeding rack 1 is provided with a slide for placing silicon rods. The feeding end of the slide is open, and a plurality of guide wheels are spaced apart along its length.
[0044] The blocking mechanism 13 is located at the feeding end of the slide, and the blocking mechanism 13 can be raised and lowered.
[0045] The feeding mechanism includes a feeding component, a first sensor 4, a second sensor 5, a third sensor 6, and a rope sensor 7.
[0046] The feeding component moves along the length of the slide and drives the silicon rod to move. In this embodiment, the feeding component is a suction cup 2 and its linear movement mechanism 3. The suction cup 2 is located at the feeding end away from the slide. The linear movement mechanism 3 includes a slide rail and a drive component. The slide rail and drive component are located on the lower side of the slide. The suction cup 2 is opposite to the end of the silicon rod on the slide. Its lower end moves in cooperation with the slide rail and is driven by the drive component to move along the length of the slide.
[0047] The fixed end of the pull rope sensor 7 is connected to the feeding rack 1, and the movable end of the pull rope sensor 7 is connected to the suction cup 2.
[0048] The first sensor 4 serves as a detection sensor and is electrically connected to the blocking mechanism 13. The first sensor 4 is used to detect the presence status of the silicon rod at the feeding end of the slide. In this embodiment, the first sensor 4 is located at the feeding end of the slide.
[0049] The second sensor 5, acting as a contact sensor, is located at the loading end of the slide. The second sensor 5 cooperates with the silicon rod transfer device to determine the proper placement of the silicon rod. In this embodiment, the silicon rod transfer device is an AGV (Automated Guided Vehicle). After reaching the loading end of the slide, it contacts the second sensor 5 to sense its position. Then, the AGV's built-in moving and pushing mechanism pushes the silicon rod into the slide. Simultaneously, the suction cup 2 of the loading assembly approaches the end of the silicon rod to adsorb it and pull it into the slide.
[0050] The third sensor 6 is mounted on the slide rail and is used to detect the presence of silicon rods on the slide rail. In this embodiment, the third sensor 6 includes an oblique beam sensor 61 and a sensing plate 62. The oblique beam sensor 61 and the sensing plate 62 are respectively located at both ends of the slide rail and on different sides of the slide rail, covering the length of the slide rail to detect the presence of silicon rods. The third sensor 6 is electrically connected to the silicon rod transfer device. When it detects that there are no silicon rods on the loading rack 1, it sends a transfer signal to the silicon rod transfer device, so that the silicon rod transfer device transfers silicon rods to the slide rail for replenishment.
[0051] After the third sensor 6 detects that there are no silicon rods on the slide of the feeding rack 1, the silicon rod transfer device receives the signal and moves to the slide to contact the second sensor 5. Then, with the cooperation of the feeding assembly, it transfers the silicon rod onto the slide. When the silicon rod is completely inside the slide, the first sensor 4 detects that there are no silicon rods at the feeding end of the slide. The blocking mechanism 13 receives the signal and raises the blocking structure formed at the feeding end of the slide. Then, the feeding assembly pushes the silicon rod toward the blocking mechanism 13, so that the silicon rod is transferred to the designated feeding position.
[0052] Example 2
[0053] The difference between this embodiment and Embodiment 1 is that:
[0054] like Figure 1 As shown, it also includes a tilting cylinder 9 and a fixing frame 8. The fixing frame 8 is rotatably connected to the loading rack 1. The fixed end of the tilting cylinder 9 is located on the fixing frame 8, and the movable end of the tilting cylinder 9 is located on the loading rack 1. According to the processing angle of the processing mechanism, the loading angle of the silicon rod placed in the loading rack 1 and its slide can be adjusted by the tilting cylinder 9 to meet the gripping requirements of the processing mechanism.
[0055] In summary, the silicon rod feeding device provided by this utility model transfers the silicon rod to the designated feeding position by moving the feeding component along the slide, and at the same time uses the pull rope sensor to measure the length of the silicon rod during the movement of the silicon rod.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
