DETAILED DESCRIPTION

[0024] The following is a more detailed description of the implementation of the utility model in conjunction with the drawings and the figure marks, so that those skilled in the art can implement it after reading this specification. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0025] The utility model provides Figure 1-5 The polysilicon powder translation device shown includes a support frame 10, a translation support plate 20, a linear drive unit 30 for driving the translation support plate 20 to slide linearly on the support frame 10, and an anti-pollution unit for preventing powder contamination.

[0026] Please refer to Figure 3 The support frame 10 includes a pair of parallel cross beams 11 and a plurality of support beams 14 disposed between the two cross beams 11. The length of the cross beam 11 is much greater than the support beam 14, so that the support frame forms a long strip structure to meet the conveying length requirements of the powder. A guide rail 12 is disposed on the top of the cross beam 11. The two guide rails 12 are disposed in parallel and are slidably connected to the translation support plate 20.

[0027] Please refer to Figure 1 , Figure 4 The translation support plate 20 includes a plurality of support plates 22, a plurality of connecting strips 23 connected between two adjacent support plates 22, and a cover plate 24 covering the top of the connecting strips. The connecting strips 23 play a positioning role. Specifically, the support plate 22 is provided with a groove that matches the connecting strips 23. The connecting strips 23 are inserted into the grooves, and the top surface of the connecting strips 23 is flush with the support plate 22, reducing the gap between the support plate 22 and the cover plate 24. Furthermore, the cover plate 24 extends above two adjacent support plates 22 to cover the gap between the two adjacent support plates 22, prevent the powder from falling, and avoid contaminating the linear drive unit 30 under the translation support plate 20.

[0028] The support plate 22 is provided with a material frame positioning hole for fixing the tray 50, and two pairs of sliders 21 corresponding to the two guide rails 12 are provided at the bottom of each of the support plates 22 to enhance the stability of the support, so that each support plate 22 can stably support a tray 50 and a material frame 60 arranged on the tray. In this embodiment, the material frame positioning holes include four first material frame positioning holes 25 respectively arranged at the four corners of the support plate 22 and four second material frame positioning holes 26 arranged at the center of the support plate 22, and the first and second material frame positioning holes are respectively suitable for two different trays 50.

[0029] The linear drive unit 30 is disposed between the two beams 11 and below the translation support plate 20, which can reduce the volume and protect the linear drive unit 30 inside to prevent it from being contaminated by scattered powder and affecting its service life. Figure 3 The linear drive unit 30 includes a drive motor 31, a screw rod 32 rotatably connected to the support frame 10, and a nut 33 threadedly connected to the screw rod 32. The drive motor 31 is bolted to a support beam 14, and both support beams 14 are provided with a bearing seat 34. The screw rod 32 is rotatably connected to the bearing seat 34. The output shaft of the drive motor 31 is connected to one end of the screw rod 32, and the nut 33 is connected to the translation support plate 20. The drive motor 31 drives the screw rod 32 to rotate, and then drives the translation support plate 20 to slide along the guide rail 12 through the nut 33 to achieve reciprocating conveying of powder.

[0030] The anti-pollution unit is used to prevent powder from contaminating the moving components, enhance stability and extend service life. The anti-pollution unit includes two protective plates 41 respectively arranged on both sides of the bottom of the translation support plate 20. Figure 2 The two protective plates 41 are respectively located on the side of the two beams 11 away from each other. The protective plates 41 extend toward the beam 11 and cover the gap between the translation support plate 20 and the beam 11. The width of the guide rail 12 is smaller than that of the beam 11. The protective plates 41 can prevent powder from entering from the side and contaminating the guide rail 12 and the linear drive unit 30. The cover plate 24 is bolted to the protective plates 41. Please refer to Figure 1 , Figure 5 , both ends of the support frame are provided with sealing plates 13, and the anti-pollution unit also includes a telescopic protective cover 42 connected between the translation support plate 20 and the sealing plate 13. The telescopic protective cover 42 is an inverted U-shaped structure as a whole, and the two legs arranged on both sides thereof are slidably connected with the guide rails, covering the two guide rails 12, preventing powder from entering the parts of the guide rails 12 not covered by the two ends of the translation support plate 20 to contaminate the guide rails 12 and the linear drive unit 30. The telescopic protective cover 42 can adopt a bellows-type telescopic cover, which is telescopic when the translation support plate 20 moves. Please refer to Figure 3The anti-pollution unit also includes a telescopic protective sleeve 43 connected between the nut 33 and the two bearing seats 34 to further protect the screw rod.

[0031] The above are one or more embodiments of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
