[0002] Crystal ingots are artificially prepared high-purity single-crystal silicon materials. Due to their high purity, excellent electrical properties and stable crystal structure, they are widely used in the production of integrated circuits, solar cells and microelectronic devices. Since crystal ingots are usually large in size and weight and fragile, professional lifting equipment must be used in production lines and warehousing to ensure stable handling to avoid cracks, chipping and even breakage of the crystal ingots due to collisions or vibrations, which would cause huge losses.
[0003] However, existing crystal rod lifting equipment can usually only lift crystal rods of a specific diameter. This is because the lifting tools of these equipment, such as mechanical claws and hooks, can only match preset size specifications. When the diameter of the crystal rod is smaller or larger than the preset size specifications, the existing lifting equipment is difficult to provide sufficient clamping force, and the crystal rod is prone to slipping and damage. In order to ensure that the crystal rod can be lifted stably, it is necessary to replace the lifting equipment of different specifications according to the crystal rods of different diameters, resulting in reduced crystal rod handling efficiency.

[0036] Please refer to Figures 3 to 5 Furthermore, two mounting grooves 416 are symmetrically formed at both ends of the mounting frame 411, and a mounting hole 417 is formed on the side of each mounting groove 416 and passes through the mounting groove 416; the lifting member 40 also includes two protective components 43 with the same structure, and the two protective components 43 are installed on both sides of the mounting frame 411. Each protective component 43 includes a baffle 431 and two protective rods 432 with the same structure. The baffle 431 is fixedly connected to the first ends of the two protective rods 432 to block the crystal rod and prevent the crystal rod from slipping off the clamping component 42; the second end of each protective rod 432 can be slidably installed in a mounting groove 416 to adjust the protruding length of the protective rod 432 according to the length of the crystal rod, so that the baffle 431 can block the crystal rod; at least two fixing holes 433 are evenly opened on each protective rod 432, and each fixing hole 433 is used to be fixedly connected to the mounting hole 417, for example, fixedly connected by bolts to lock the protective rod 432; specifically, when clamping a horizontally placed crystal rod, there is no need to install the protective component 43; when the crystal rod needs to be transformed from a horizontal state to a vertical state, since the crystal rod is easily affected by gravity and slips during the posture conversion process, it is necessary to install the protective component 43, and by adjusting the length of the protective rod 432 extending out of the mounting slot 416, the baffle 431 can be in contact with one end of the crystal rod, thereby providing support force for the crystal rod during the posture conversion process of the crystal rod, thereby blocking the crystal rod and preventing the crystal rod from slipping.
[0037] Furthermore, a soft protective pad 434 , such as polyurethane, is provided on the inner side of the baffle 431 to prevent the baffle 431 from abrading the two ends of the crystal rod.
[0038] Example 1, working process of the crystal ingot lifting and transportation device 10 1. The operator pushes the ingot hoisting and transporting device 10 to the ingot storage area using the handrail 225. The front wheels 223 provide directional travel force, and the universal wheels 224 of the rear wheel frame 222 flexibly adjust the direction. 2. Start the two first drive motors 313 of the height adjustment assembly 31, driving the two first adjustment rods 311 to rotate synchronously. Driven by the screw drive, the adjustment platform 312 rises and falls in the vertical direction, driving the lifting member 40 to reach the crystal ingot clamping height; 3. The third drive motor 413 drives the second adjustment rod 412 to rotate. Driven by the second adjustment rod 412, the clamping frames 421 of each clamping assembly 42 move synchronously along the limiting groove 415, adjusting the spacing between the clamping assemblies 42 to adapt to the length of the crystal ingot. 4. Telescopic member 425 pushes straight clamp 4221 out along first slide chute 4214. Straight clamp 4221 drives two curved clamps 4222 to move synchronously via first synchronizing gear 4223 and second synchronizing gear 4224. Three V-shaped clamps 4225 simultaneously approach and contact the surface of the ingot, creating a uniformly distributed clamping force that adapts to ingots of varying diameters. Simultaneously, first synchronizing rod 423 and second synchronizing rod 424 force the two side clamps 422 to move synchronously, ensuring balanced clamping force. 5. The height adjustment assembly 31 lifts the lifting member 40 to separate the crystal ingot from the rack; 6. After the operator pushes the device to the target position, the height adjustment assembly 31 descends to the placement height, and the telescopic member 425 retracts so that the three V-shaped clamps 4225 are synchronously moved away from the crystal ingot to release the crystal ingot.
[0039] Example 2: The process of converting a horizontally clamped crystal rod into a vertical state 1. After clamping the horizontally placed crystal ingot, insert the second ends of the four protection rods 432 of the two protection assemblies 43 into the four corresponding mounting slots 416; 2. Based on the actual length of the crystal ingot, slide the protective rod 432 along the mounting slot 416 and preliminarily adjust its extension length so that the baffle 431 moves to a position close to the end face of the crystal ingot; 3. Finely adjust the extension length of the protective rod 432 to ensure that the soft pad 434 inside the baffle 431 lightly contacts the end face of the ingot. Then, insert the bolt into the mounting hole 417 and the aligned fixing hole 433 and tighten it to lock the protective rod 432 in place. 4. The two telescopic rods 332 of the angle adjustment assembly 33 are retracted synchronously, pulling the lifting frame assembly 41 to rotate to a vertical position; 5. The second drive motor 323 of the direction adjustment assembly 32 is started, driving the rotating shaft 322 to rotate 90°, and the crystal rod is rotated to a vertical state along with the lifting frame assembly 41.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
