Description

Technical Field

[0001] The utility model relates to the technical field of single crystal silicon rods, in particular to a single crystal silicon rod transfer vehicle. Background Art

[0002] Single crystal silicon rods are used to manufacture semiconductor devices and solar cells. Single crystal silicon rods are formed by shaping or pulling in a furnace through zone melting or direct pulling processes. They are single crystal silicon rods in which silicon atoms are rearranged according to the lattice arrangement direction of the seed crystal. The announcement number is: CN 214451186 U, which discloses a single crystal silicon rod transfer device, including a transfer box. The four corner ends of the bottom surface of the transfer box are provided with buffer devices. The buffer device includes a connecting tube, a load-bearing column, a mounting block and a second compression spring. A partition is provided at the inner center of the transfer box. Multiple groups of upper and lower symmetrical clamping devices are provided between the partition and the inner wall of the transfer box. The clamping device includes a fixed tube, a fixed rod, a first compression spring, a stop block, a movable column, a clamping block and a rubber block. The utility model describes a single crystal silicon rod transfer device, which belongs to the field of single crystal silicon rods. Through the coordinated use of the provided transfer box, partitions and clamping devices, multiple single crystal silicon rods can be transported at one time, and the single crystal silicon rods can be clamped and fixed up and down during transportation. The provided buffer device is used to play a buffering and shock-absorbing role to avoid collisions between the single crystal silicon rods during transportation, which may affect the quality of the single crystal silicon rods.

[0003] The above solution has the following shortcomings when used: when placing the single crystal rod in the clamping device, it is necessary to squeeze the clamping block against the single crystal silicon rod to generate a rebound force while causing it to contract, and then use the rebound force to fix the single crystal rod. That is, the single crystal rod will also be affected by the elastic force of the spring when squeezing the clamping block, making it difficult to squeeze into the clamping block, making the operation cumbersome when loading the single crystal rod, and the upper and lower clamping is difficult to adjust according to the length of the single crystal rod. Utility Model Content

[0004] In response to the deficiencies of the prior art, the utility model provides a single crystal silicon rod transfer vehicle, which has the advantages of easy loading and length adjustment, avoiding the problems of cumbersome loading and clamping and difficulty in adjusting the length of the device according to the length of the single crystal rod.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figure 1-4 A single crystal silicon rod transfer vehicle includes a main frame 1, with multiple transverse partitions 101 fixedly connected to both side walls of the main frame 1, vertical partitions 102 fixedly connected to both sides of the inner wall of the main frame 1, and fixing components 2 installed on the vertical partitions 102 and the side walls of the main frame 1. The fixing components 2 are used to fix the single crystal silicon rods. The inner cavity of the main frame 1 is installed with an adjustment component 3, which is used to adjust the length of the main frame 1. The vehicle also includes:

[0022] The fixing assembly 2 includes a sleeve 201, which is fixed to the vertical partition 102 and the side wall of the main frame 1. A sliding column 202 is slidably connected to the inner wall of the sleeve 201. A fixing plate 203 is fixedly connected to the end of the sliding column 202 located outside the sleeve 201. A spring 204 is fixedly connected between the sleeve 201 and the sliding column 202. A rotating column 205 is rotatably connected to the top of the vertical partition 102 and the main frame 1. The rotating column 205 extends to the inner cavity of the vertical partition 102 and the main frame 1. A connecting rope 206 is fixedly connected between the rotating column 205 and the sliding column 202.

[0023] The side wall of the rotating column 205 is threadedly connected with a fixing bolt 207, which is used to fix the rotating column 205. The side wall of the fixing plate 203 is set to an arc shape;

[0024] It should be noted that: the length of the main frame 1 is adjusted by using the adjustment component 3 to adapt to the length of the single crystal silicon rod that needs to be transported, and the rotating column 205 is rotated. The rotating column 205 rotates to wrap the connecting rope 206 around its side wall. At this time, the connecting rope 206 pulls the sliding column 202 and the fixed plate 203 to slide toward the inner cavity of the sleeve 201, and the fixed plates 203 move away from each other, and the spring 204 is compressed. The fixing bolt 207 is rotated to fix the rotating column 205. At this time, the single crystal silicon rod is placed on the top of the transverse partition 101, and the single crystal rod is located between the fixed plates 203. After all the single crystal rods are placed, the fixing bolt 207 and the rotating column 205 are rotated in the opposite direction to relax the connecting rope 206. At this time, under the action of the spring 204, the sliding column 202 drives the fixed plate 203 to slide to the middle, thereby fixing the single crystal rod between the fixed plates 203, which is simple and convenient.

[0025] Reference Figure 1-4 The adjustment assembly 3 includes a connecting plate 303, which is slidably connected and installed between the main frames 1. The main frame 1 is divided into a first bracket 301 and a second bracket 302, and is symmetrical about the center line of the connecting plate 303;

[0026] The inner walls of the first bracket 301 and the second bracket 302 are both rotatably connected to a bidirectional threaded rod 304, and the side walls on both sides of the bidirectional threaded rod 304 are both threadedly connected to a connecting frame 305, and a connecting rod 306 is rotatably connected between the connecting frames 305;

[0027] It should be noted that: when adjusting the length of the main frame 1, the bidirectional threaded rod 304 is rotated. Since the bidirectional threaded rod 304 is threadedly connected to the connecting frame 305 on both sides, when the connecting frames 305 move away from each other, the connecting rod 306 between the connecting frames 305 is unfolded, and the first bracket 301 and the second bracket 302 move away from each other, thereby increasing the length of the main frame 1. When the connecting frames 305 move closer to each other, the connecting rod 306 contracts, and the first bracket 301 and the second bracket 302 move closer to each other, thereby reducing the length of the main frame 1, which is convenient for adapting to the length of the single crystal silicon rod, and the first bracket 301 and the second bracket 302 are connected by the connecting plate 303.

[0028] Reference Figure 1-4 The first bracket 301, the second bracket 302 and the bottom of the connecting plate 303 are all rotatably connected to a rotating wheel 307, and the side wall of the main frame 1 is fixedly connected to a push rod 308;

[0029] The fixing assembly 2 corresponds to the diaphragm 101 one by one, and the fixing assembly 2 is located above the corresponding diaphragm 101, and the fixing plate 203 is set with a flexible material;

[0030] It should be noted that the main frame 1 is moved by the push rod 308 and the rotating wheel 307 at its bottom, which facilitates the transportation of single crystal rods, and since the fixing components 2 and the diaphragm 101 correspond one to one, the single crystal rods placed on the surface of the diaphragm 101 can be fixed one by one.

[0031] Operation method: Use the adjustment component 3 to adjust the length of the main frame 1 by rotating the bidirectional threaded rod 304. Since both sides of the bidirectional threaded rod 304 are threadedly connected to the connecting frames 305, when the connecting frames 305 move away from each other, the connecting rod 306 between the connecting frames 305 is expanded, and the first bracket 301 and the second bracket 302 move away from each other, thereby increasing the length of the main frame 1. When the connecting frames 305 move closer to each other, the connecting rod 306 contracts, and the first bracket 301 and the second bracket 302 move closer to each other, thereby reducing the length of the main frame 1 to facilitate adapting to the length of the single crystal silicon rod. The first bracket 301 and the second bracket 302 are connected by the connecting plate 303;

[0032] The rotating column 205 is rotated, and the rotating column 205 rotates to wrap the connecting rope 206 around its side wall. At this time, the connecting rope 206 pulls the sliding column 202 and the fixed plate 203 to slide toward the inner cavity of the sleeve 201. The fixed plates 203 move away from each other, and the spring 204 is compressed. The fixing bolt 207 is rotated to fix the rotating column 205. At this time, the single crystal silicon rod is placed on the top of the transverse partition 101, and the single crystal rod is located between the fixed plates 203. After all the single crystal rods are placed, the fixing bolt 207 and the rotating column 205 are rotated in the opposite direction to loosen the connecting rope 206. At this time, under the action of the spring 204, the sliding column 202 drives the fixed plates 203 to slide toward the middle, thereby fixing the single crystal rod between the fixed plates 203. It is simple and convenient.

[0033] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
