Description

Technical Field

[0001] This utility model relates to the technical field of silicon rod conveying, and in particular to a lifting, centering, and clamping device for silicon rod conveying. Background Technology

[0002] Monocrystalline silicon is an important component of crystalline materials and is at the forefront of new material development. It is used to manufacture high-power rectifiers, high-power transistors, diodes, and switching devices, and is a promising material for energy development. Monocrystalline silicon rods are grown in rod shape from a furnace using the Czochralski method or the floating zone melting method in industrial production. When transporting silicon rods on a crystal rod grinding machine, they need to be firmly fixed by clamps.

[0003] Currently, the lifting, centering, and clamping device for transporting silicon rods in silicon rod grinding machines is not easy to adjust, cannot adapt to silicon rods of different diameters, has poor applicability, and lacks a centering function, which affects the transport of silicon rods. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a lifting and centering clamping device for silicon rod conveying that is easy to use, can adapt to different specifications of products, and has a good clamping effect.

[0005] The technical solution adopted by this utility model is as follows: This utility model includes a lifting mechanism, the lifting end of which is provided with a lifting platform. The lifting platform is provided with a clamping station, a first driving mechanism, and a second driving mechanism. The clamping station is provided with two pressing rollers and two supporting rollers. The two pressing rollers are located above the two supporting rollers. The first driving mechanism includes two movable rods. The two pressing rollers are respectively provided at one end of the two movable rods. The other ends of the two movable rods are rotatably connected to the lifting platform. The inner side of each of the two movable rods is provided with a limit groove. A movable slider is provided in the limit groove. A tension spring is connected between each of the two movable sliders and the lifting platform. The second driving mechanism can drive the two supporting rollers to clamp / release.

[0006] Furthermore, the second drive mechanism includes a lead screw, a guide rod, and a third drive mechanism built into the lifting platform. The lead screw has a bidirectional thread, and two moving rods are connected to the lead screw. Both moving rods are connected to the guide rod. The lifting platform has a clearance hole, and the upper ends of the two moving rods extend out of the clearance hole. The two support clamping wheels are located at the upper ends of the two moving rods respectively. The third drive mechanism can drive the lead screw transmission.

[0007] Furthermore, the third drive mechanism includes a first rotating block, which is connected to the lead screw.

[0008] Furthermore, the lifting mechanism includes a lifting base and a lifting cylinder, the lower end of the lifting cylinder is located in the lifting base, the lifting platform is located at the upper end of the lifting cylinder, and a fourth driving mechanism is provided on the lifting base, which can drive the lifting cylinder to move.

[0009] Furthermore, the fourth driving mechanism includes a screw and a driving rod. The screw is mounted on the lifting cylinder and connected to a rotating rod. A geared disc is sleeved on the rotating rod. One end of the driving rod is provided with bevel teeth that mesh with the geared disc, and the other end is provided with a second rotating block.

[0010] Furthermore, guide blocks are provided at both ends of the lifting cylinder, and two guide grooves are provided in the lifting base, with the two guide grooves respectively cooperating with the two guide blocks.

[0011] Furthermore, a seat plate is provided at the bottom of the lifting base.

[0012] Furthermore, both sides of the lifting platform have L-shaped brackets, and the two movable rods are rotatably connected to the two L-shaped brackets respectively.

[0013] Furthermore, one end of the tension spring is connected to the lifting platform via a first hinge seat, and the other end of the tension spring is connected to the movable slider via a second hinge seat.

[0014] The beneficial effects of this utility model are:

[0015] In contrast to the shortcomings of existing technologies, this invention utilizes a second driving mechanism to drive two support clamping wheels to clamp / release, enabling them to clamp the silicon rod located at the clamping station and provide auxiliary support. This more effectively coordinates with the two pressing rollers to limit and hold the silicon rod. The tension spring, combined with the movable slider sliding along the guide groove, causes the two pressing rollers to move closer to the center of the clamping station, thus achieving centering clamping of the silicon rod. Therefore, this invention, through the tension spring and the movable slider sliding along the guide groove, allows the two pressing rollers to move closer to the center of the clamping station, achieving centering clamping of the silicon rod. This method can accommodate silicon rods of different diameters, is convenient to use, and has strong adaptability. These advantages make this invention easy to use, adaptable to different product specifications, and provide excellent clamping effect. Attached Figure Description

[0028] like Figures 1 to 5 As shown, in this embodiment, the present invention includes a lifting mechanism 1, the lifting end of which is provided with a lifting platform 2. The lifting platform 2 is provided with a clamping station, a first driving mechanism 3, and a second driving mechanism 4.

The other end of the two movable rods 7 is rotatably connected to the lifting platform 2. The inner side of each of the two movable rods 7 is provided with a limiting groove 8. A movable slider 9 is provided in the limiting groove 8. A tension spring 10 is connected between each of the two movable sliders 9 and the lifting platform 2. The second driving mechanism 4 can drive the two supporting rollers 6 to clamp / release.

[0029] Compared with the shortcomings of the prior art, in this utility model, the second driving mechanism 4 can drive the two supporting clamping wheels 6 to clamp / release, so that the two supporting clamping wheels 6 can clamp the silicon rod located at the clamping position to play an auxiliary support role, and more effectively cooperate with the two pressing abutment wheels 5 to limit and clamp the silicon rod; through the elastic force of the tension spring 10 and the movable slider 9 sliding along the guide of the limiting slide groove 8, the two pressing abutment wheels 5 move closer to the center of the clamping position, thereby achieving the centering clamping of the silicon rod. Therefore, this utility model, through the elastic force of the tension spring 10 and the movable slider 9 sliding along the guide of the limiting slide groove 8, makes the two pressing abutment wheels 5 move closer to the center of the clamping position, thereby achieving the centering clamping of the silicon rod. It can adapt to silicon rods of different diameters, is easy to use, and has strong adaptability. This utility model has the advantages of being easy to use, adaptable to different specifications of products, and having a good clamping effect.

The third driving mechanism 13 includes a first rotating block 17, which is connected to the lead screw 11. Specifically, by setting the first rotating block 17 and the lead screw 11 with bidirectional thread in conjunction with the guide rod 12, the two moving rods 15 can be limited to move away from and closer to each other in a straight line, so as to drive the two support clamping wheels 6 to provide auxiliary support for the bottom of silicon rods of different specifications, and more effectively cooperate with the clamping rollers 5 to limit and clamp the silicon rods.

[0032] like Figure 1 As shown, in some embodiments, both sides of the lifting platform 2 have L-shaped brackets 31, and the two movable rods 7 are rotatably connected to the two L-shaped brackets 31 respectively; one end of the tension spring 10 is connected to the lifting platform 2 through the first hinge seat 32, and the other end of the tension spring 10 is connected to the movable slider 9 through the second hinge seat 33.

[0033] The usage process of this utility model is as follows:

[0034] In use, the first rotating block 17 and the lead screw 11 with bidirectional threads, in conjunction with the guide rod 12, can limit the movement of the two auxiliary moving rods 15 in a straight line, moving them away from each other and closer together, so as to drive the two support clamping wheels 6 to provide auxiliary support for the bottom of silicon rods of different specifications; the elastic force of the tension spring 10, in conjunction with the movable slider 9 sliding along the guide groove 8, causes the two pressing rollers 5 to move closer to the center, thereby achieving centering and clamping of the silicon rod; the rotating rod 23, the lead screw 21, the gear plate 25, the bevel gear 26, the drive rod 22, and the second rotating block 27, in conjunction with the guide block 28 sliding along the guide groove 29, can limit the movement of the auxiliary lifting cylinder 19 along the length direction of the lead screw 21 to adjust the working height of the lifting platform 2.
