The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0018] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0019] refer to Figure 1 and Figure 2 This application provides a silicon rod adhesive fixing device, including a base plate 10 and a mounting frame 20 connected to the top of the base plate 10. The mounting frame 20 includes a horizontal frame 21 and vertical frames 22 symmetrically and vertically connected to both ends of the horizontal frame 21. The base plate 10 is connected by the two vertical frames 22. A crystal boat 11, a resin plate, a silicon rod 12 and a guide strip are placed sequentially on the top of the base plate 10. At the same time, the horizontal frame 21 is located directly above the silicon rod 12, that is, directly above the crystal boat 11, the resin plate, the silicon rod 12 and the guide strip. At least one cylinder assembly 30 is mounted on the crossbeam 21, and the cylinder assembly 30 includes two cylinders 31 arranged side by side along the same height direction. The telescopic shafts of the cylinders 31 are located at the bottom, and the telescopic shafts of the two cylinders 31 are simultaneously and vertically connected to the same pressure rod 32. The bottom of the pressure rod 32 is provided with a buffer pad 33 so that the pressure rod 32 can be driven to press down the guide strip by the synchronous extension of the two cylinders 31, thereby completing the gluing operation of the silicon rod 12. The number of cylinder assemblies 30 depends on the extension range of the base plate 10, the installation space of the crossbeam 21, and the length of the silicon rod 12. It can simultaneously complete the gluing work of multiple silicon rods 12, and can also complete the gluing work of silicon rods 12 of different lengths, with a wide range of applications. For example, each cylinder assembly 30 can press down a shorter silicon rod 12, or two cylinder assemblies 30 can simultaneously press down a longer silicon rod 12, etc.

[0020] In one embodiment, two cylinder assemblies 30 are mounted on the crossbeam 21.

[0021] Therefore, the silicon rod adhesive fixing device provided in this application automatically presses down the pressure rod 32 driven by the cylinder 31 to complete the adhesive fixing of the guide strip, silicon rod 12, resin plate and crystal boat 11. It has high working efficiency, high standardization and good stability. In addition, by setting a buffer pad 33 at the bottom of the pressure rod 32, the guide strip can be fully fixed during the pressing process and the pressure can be distributed to prevent the guide strip from warping and deforming. This ensures the adhesive quality of silicon rod 12 and the subsequent cutting quality.

[0022] In one embodiment, a pressure gauge 221 and a pressure display 222 are installed on one of the two vertical supports 22. The pressure gauge 221 is connected to the cylinder 31 and is used to set the initial pressure value of the cylinder 31 through a proportional valve after the air source is turned on. In addition, a pressure sensor 321 is installed on the pressure rod 32 and is connected to the pressure display 222 to display the pressure data of the pressure rod 32 in real time. A lifting controller 223 is installed on the other vertical support 22 to control the cylinder. The lifting and lowering of cylinder 31 can be achieved by adjusting the air pressure to ensure that the downward pressure of cylinder 32 remains stable within the set range. Specifically, after cylinder 31 is connected to the air source, the initial air pressure value of cylinder 31 is set through the proportional valve, and the pressure data is monitored in real time by the pressure sensor 321 during the pressing process. The control system automatically fine-tunes the opening of the proportional valve based on the feedback, thereby ensuring that the downward pressure can be stably maintained within the set range and achieving precise control of the downward pressure to adapt to the adhesive fixing requirements of silicon rods 12 and guide strips of different sizes. The proportional valve is located inside cylinder 31, or in other words, cylinder 31 has a built-in proportional valve.

[0023] In one embodiment, the top of the base plate 10 is symmetrically provided with guide rails 13 on the left and right sides along a predetermined direction. At the same time, the bottom ends of the two vertical frames 22 are respectively equipped with sliders 224 that slide in cooperation with the guide rails 13. This allows the mounting frame 20 to move directionally on the base plate 10. Before pressing down, the mounting frame 20 can be moved away from the position of the crystal boat 11 to facilitate the placement of the resin board, silicon rod 12 and guide strip on the crystal boat 11 in sequence. Then the mounting frame 20 is moved into place and the pressing down is started for adhesive fixation. This facilitates the quick and accurate placement of various items and helps to improve work efficiency.

[0024] In one embodiment, the guide rail 13 is a U-shaped guide rail, and correspondingly, the slider 224 is a U-shaped slider. Meanwhile, triangular angle irons 225 are symmetrically connected to both sides of the bottom of the vertical frame 22, and the bottom of the triangular angle irons 225 is connected to the top of the slider 224, thereby improving the connection strength and structural stability between the vertical frame 22 and the slider 224.

[0025] In one embodiment, the extension direction of the crossbeam 21 is perpendicular to the extension direction of the guide rail 13. The crossbeam 21 is composed of two square aluminum profiles 211 arranged side by side at the same height. The cylinder 31 is installed between the two square aluminum profiles 211 in a manner that allows it to move in a horizontal direction and is fixed by fastening screws. This allows the cylinder 31 to move in a horizontal direction and be fixed by fastening screws after it has moved into place. This allows the cylinder assembly 30 and the pressure rod 32 to be flexibly changed to press down silicon rods 12 of different lengths or positions.

[0026] In one embodiment, infrared sensor probes 212 are symmetrically mounted on the two square aluminum profiles 211, with the detection ends of the infrared sensor probes 212 located at the bottom, so as to detect the position of the crystal boat 11 through the two infrared sensor probes 212. That is, after the crystal boat 11, resin plate, silicon rod 12 and guide strip are placed in place, the mounting bracket 20 is manually moved. The movement stops when the infrared rays emitted by the infrared sensor probes 212 on the two vertical brackets 22 hit the two side walls of the crystal boat 11 respectively. At this time, the pressure rod 32 is directly facing the silicon rod 12, and thus the infrared sensor probes 212 can play a positioning role, ensuring the accuracy of the pressing position, and thus ensuring the quality of adhesive fixation.

[0027] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
