Furthermore, stacking or retrieving the cores requires frequent bending over or tiptoeing, making operation inconvenient. Utility Model Content

[0005] This utility model provides a silicon core stacking rack to solve the problems mentioned in the background art, such as the inability to flexibly adjust according to the size of the silicon core, poor applicability, and the inconvenience of frequently bending over or tiptoeing when stacking or retrieving the core.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figure 1-5 As shown, the square silicon core stacking rack includes a base 1, with universal wheels 2 rotatably connected to the four corners of the bottom of the base 1, multiple support frames 3 on the top of the base 1, a lifting mechanism 4 on the outside of the support frames 3, and an auxiliary cooling mechanism 5 on the top of the base 1.

[0027] The lifting mechanism 4 includes multiple hinge frames 40, multiple threaded rods 41, and multiple rotating seats 45. The multiple hinge frames 40 are all arranged between two support frames 3. The bottom of the multiple threaded rods 41 is rotatably connected to the top of the base 1. The threaded rods 41 are threadedly connected to the outer periphery of the threaded rods 41 with threaded sleeves 42. The top of the threaded sleeves 42 is fixedly connected to a fixing block 43. The outer periphery of the threaded rods 41 is fixedly connected to a worm gear 44. The bottom of the multiple rotating seats 45 is fixedly connected to the top of the base 1. The rotating seats 45 are rotatably connected to a worm gear 46 inside. The outside of the worm gear 46 is fixedly connected to a crank handle 47.

[0028] It should be noted that when adjusting the spacing of the support frame 3 according to the height of the silicon core, turning the handle 47 drives the worm gear 46 to rotate within the rotating seat 45. The worm gear 46 meshes with the worm wheel 44, causing the threaded rod 41 to rotate synchronously. The threaded sleeve 42 moves up and down along the threaded rod 41, pushing or pulling the support frame 3 to rise and fall through the fixing block 43. The hinge frame 40 between adjacent support frames 3 extends and retracts with the movement of the support frame 3, ensuring that each layer of support frame 3 rises and falls synchronously and remains horizontal. After adjustment, the silicon core can be placed stably on the support frame 3 to avoid squeezing or shaking caused by unsuitable layer height.

[0029] The auxiliary cooling mechanism 5 includes a mounting plate 50, which is fixedly connected to the top of the base 1 on the outside. A motor base 51 is fixedly connected to the outside of the mounting plate 50, and a motor 52 is fixedly connected to the outside of the motor base 51. A disc 53 is fixedly connected to the output end of the motor 52. An eccentric shaft 54 ​​is fixedly connected to the outer edge of the disc 53. A movable frame 55 is slidably connected to the outer circumference of the eccentric shaft 54. Two connecting blocks 56 are fixedly connected to the outside of the movable frame 55. Two fixed shafts 57 are fixedly connected to the outside of the connecting blocks 56. A mounting block 58 is rotatably connected to the outside of the fixed shafts 57. A rotating shaft 59 is rotatably connected inside the mounting block 58. An air supply nozzle 510 is fixedly connected to the outside of the mounting block 58, and an air supply pipe 511 is fixedly connected to the outside of the air supply nozzle 510.

[0030] It should be noted that when cooling the stacked squaring silicon cores, the air supply pipe 511 is connected to the air cooler, the motor 52 is started to drive the disc 53 to rotate in the motor base 51, the eccentric shaft 54 ​​slides in the moving frame 55, so that the moving frame 55 slides back and forth along the mounting plate 50 and the motor base 51. The moving frame 55 drives the mounting block 58 to swing left and right around the rotating shaft 59 through the connecting block 56 and the fixed shaft 57. The air supply nozzle 510 swings synchronously with the mounting block 58, blowing cold air evenly to the surface of each layer of squaring silicon cores, accelerating air circulation, reducing ambient temperature, and improving production line efficiency.

[0031] like Figure 2 As shown, the outer side of the fixing block 43 is fixedly connected to the outer side of the support frame 3.

[0032] It should be noted that the fixing block 43 fixes the threaded sleeve 42 to the support frame 3, so that the up and down movement of the threaded sleeve 42 can directly drive the support frame 3 to rise and fall, thereby realizing the adjustment of the floor height.

[0033] like Figure 2 As shown, the worm gear 44 and the worm 46 are meshed.

[0034] It should be noted that the meshing transmission between the worm gear 44 and the worm 46 has a self-locking property. After adjustment, it can prevent the threaded rod 41 from rotating on its own, ensuring the height stability of the support frame 3 and preventing the silicon core from slipping off.

[0035] like Figure 4 , Figure 5 As shown, the movable frame 55 is slidably connected to the outside of the mounting plate 50.

[0036] It should be noted that the mounting plate 50 provides guidance and support for the reciprocating motion of the moving frame 55, ensuring its stable movement trajectory and enabling the subsequent swing mechanism to move accurately.

[0037] like Figure 5 As shown, the outer side of the disk 53 is rotatably connected to the inside of the motor base 51.

[0038] It should be noted that the motor base 51 provides rotational support for the disc 53, ensuring the stable rotation of the eccentric shaft 54 ​​and providing power for the movement of the moving frame 55.

[0039] like Figure 5 As shown, the outer side of the movable frame 55 is slidably connected to the inside of the motor base 51.

[0040] It should be noted that the motor base 51 cooperates with the mounting plate 50 to further restrict the movement direction of the moving frame 55, prevent it from shaking or deviating, and ensure smooth transmission.

[0041] like Figure 4 As shown, both ends of the rotating shaft 59 are fixedly connected to the inside of the mounting plate 50.

[0042] It should be noted that the rotating shaft 59 provides a fixed fulcrum for the swing of the mounting block 58, enabling the mounting block 58 to rotate stably around it and realize the angle adjustment of the air supply nozzle 510.

[0043] The working principle of this utility model is as follows: When in use, the stacking rack is pushed to the working area by the casters 2. The handle 47 is turned according to the size of the silicon core. The height of the support frame 3 is adjusted by the lifting mechanism 4. After adjustment, the silicon cores are placed on the support frame 3 in sequence. If cooling and ventilation are required, the air supply pipe 511 is connected to the air cooler. The motor 52 of the auxiliary cooling mechanism 5 is started, so that the air supply nozzle 510 swings to deliver air and cool the silicon core evenly. When transporting, the base 1 can be pushed to move the silicon core by the casters 2. There is no need to frequently move the silicon core, which reduces the risk of damage.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
