Description

Technical Field

[0001] The utility model relates to a maintenance tube feeding machine for a tubular high-temperature furnace, belonging to the field of auxiliary equipment for maintenance of tubular high-temperature furnaces. Background Art

[0002] With the rapid development of the photovoltaic industry, the use of silicon wafer components has become more widespread. In the processing of silicon wafer components, a tubular high-temperature furnace is required, and the heating tube inside the tubular high-temperature furnace needs to be replaced regularly during use. Due to factors such as the heavy weight of the heating tube, the high installation position of the heating tube, and the small space inside the tubular high-temperature furnace, conventional equipment cannot enter, which brings great difficulties to tube replacement. At present, when replacing the heating tube, it is usually necessary for multiple people to cooperate in manually lifting the tube, which has a high labor intensity for the workers, and because it needs to be lifted to a high place, there are certain safety hazards.

[0003] To this end, a Chinese utility model patent with authorization announcement number CN220578829U discloses a diffusion furnace tube replacement and transportation device. Although it can replace manual transportation of the heating tube, it can only lift and laterally transport the heating tube, and cannot adjust the angle and horizontal position of the heating tube. Therefore, the transportation operation of the heating tube is inconvenient, which affects the tube replacement efficiency. Utility Model Content

Through the lifting mechanism 3 and the lifting drive mechanism 2, the lifting of the heating pipe can be realized, so as to realize the adjustment of the height position of the heating pipe; the lateral displacement mechanism 4 is used to drive the rotary mechanism 5 and the heating pipe carrying mechanism 6 to move laterally, and the lateral movement of the heating pipe can be realized, so as to realize the adjustment of the horizontal position of the heating pipe; the rotary mechanism 5 is used to realize the rotation of the heating pipe carrying mechanism 6, so as to realize the adjustment of the angle of the heating pipe; the heating pipe carrying mechanism 6 is used to carry the heating pipe.

[0032] The pipe feeding machine for maintaining a tubular high-temperature furnace according to the present utility model can accurately push the heating pipe to the next process by adjusting the height position, horizontal position and angular position of the heating pipe, and the operation is simple and convenient, thus effectively improving the pipe changing efficiency.

[0033] Embodiment 2:

[0034] As Figures 1 to 8 shown, on the basis of Embodiment 1,

[0035] Further, the lifting mechanism 3 includes a scissor-type connecting rod 7. The upper end of the scissor-type connecting rod 7 is connected to a lifting platform 10, and the lower end of the scissor-type connecting rod 7 is connected to a fixed shaft 8 and a moving shaft 9, with simple structure, stable operation and low manufacturing cost;

[0036] Further, the lifting drive mechanism 2 includes two linear guide rails 17 fixedly connected to the base 1, a first motor base 13, a bearing block 14, and two hinge seats 11. A moving plate 15 is slidably connected between the two linear guide rails 17. A lifting motor 12 is installed on the first motor base 13.

A moving nut is connected to the lead screw 16, and the moving nut is fixedly connected to the moving plate 15. The fixed shaft 8 is rotatably connected to the two hinge seats 11. The moving shaft 9 is fixedly connected to the moving plate 15. By the action of the lifting motor 12, the lead screw 16 is driven to rotate, thereby driving the moving nut to move, and further driving the moving shaft 9 to move through the moving plate 15, so as to realize the action of the scissor link 7, and finally realize the lifting action of the lifting platform 10;

[0037] Further, the lateral displacement mechanism 4 includes two lateral displacement components and a second motor base 18. A displacement motor 32 is installed on the second motor base 18. The lateral displacement component includes a mounting seat 19. Two secondary sliding tables 23 are connected above the mounting seat 19 through two groups of second linear guiding structures. Chain wheels 28 are rotatably connected between the two ends of the two secondary sliding tables 23. A transmission chain 29 is connected between the two chain wheels 28. Two primary sliding tables 30 are connected above the two secondary sliding tables 23 through two groups of first linear guiding structures. The upper edge of the transmission chain 29 is fixedly connected to the primary sliding table 30 through a first connecting plate 31. The lower edge of the transmission chain 29 is fixedly connected to the mounting seat 19 through a second connecting plate 35. A rack 27 is connected to one of the secondary sliding tables 23. A driving shaft 25 is rotatably connected below the mounting seat 19. A through hole 34 corresponding to the driving shaft 25 penetrates through the mounting seat 19. The driving shaft 25 is coupled to the displacement motor 32. A gear 33 is installed on the driving shaft 25. The gear 33 passes through the through hole 34 and meshes with the rack 27. By the action of the displacement motor 32, the driving shaft 25 is driven to rotate, thereby driving the gear 33 to rotate.

Since the chain wheel 28 moves with the secondary sliding table 23 and the transmission chain 29 is fixedly connected to the mounting seat 19 through the second connecting plate 35, the transmission chain 29 will roll with the movement of the secondary sliding table 23, and thus drive the primary sliding table 30 to move under the action of the first connecting plate 31, realizing the synchronous expansion and contraction of the primary sliding table 30 and the secondary sliding table 23, which is not only compact in structure but also fast in operation;

[0038] Further, the two driving shafts 25 are connected by a coupling 26, which can ensure the synchronous action of the two lateral displacement components;

[0039] Further, the second linear guiding structure includes a row of lower rollers 20 rotatably arranged on the mounting base 19 and a lower wheel groove 21 arranged on the secondary slide table 23. The lower rollers 20 are correspondingly adapted to the lower wheel groove 21. The directional movement of the secondary slide table 23 relative to the mounting base 19 is realized through the cooperation of the lower rollers 20 and the lower wheel groove 21. The structure is simple and the operation is stable.

[0040] Further, the first linear guiding structure includes a row of upper rollers 24 rotatably arranged on the primary slide table 30 and an upper wheel groove 22 arranged on the secondary slide table 23. The upper rollers 24 are correspondingly adapted to the upper wheel groove 22.

[0041] Further, the slewing mechanism 5 includes a mounting plate 36. A mounting frame 37 is fixedly connected to the mounting plate 36. A support bearing 38 is mounted on the mounting frame 37. A rotating sleeve 40 is mounted on the support bearing 38. Rotating bearings 41 are mounted at both the upper and lower ends inside the rotating sleeve 40. A central shaft 39 is also connected to the mounting frame 37. The central shaft 39 passes through the support bearing 38 and is mounted in the two rotating bearings 41. The rotating sleeve 40 is supported by the support bearing 38, and the positioning of the rotating sleeve 40 is realized through the cooperation of the central shaft 39 and the rotating bearings 41, which is beneficial to improving the load-bearing capacity and operation stability of the rotating sleeve 40.

[0042] Further, the heating tube bearing mechanism 6 includes a bearing frame 42. A row of V-shaped clamping seats 43 are arranged on the bearing frame 42. During use, the heating tube is placed in the V-shaped clamping seats 43. The V-shaped clamping seats 43 can prevent the heating tube from falling due to radial rolling, ensuring the safety of the operation.

[0043] Further, a roller 44 is rotatably arranged in the V-shaped clamping seat 43. The roller 44 can reduce the friction between the heating tube and the V-shaped clamping seat 43, which not only makes it more labor-saving to push the heating tube to the next process, but also effectively prevents the heating tube from being worn.
