[0029] To address the issues of low cleaning efficiency and safety hazards associated with wiping silicon rods in existing technologies, this application provides an auxiliary flipping device.

[0030] like Figures 1 to 7As shown, the auxiliary flipping device is used to flip the silicon rod 10. The auxiliary flipping device includes a conveying device 20, a first adjusting device 30, a second adjusting device 40, and a flipping mechanism 50. The conveying device 20 is used to convey the silicon rod 10. The first adjusting device 30 includes a first adjusting part 31 that can move along a first direction. The second adjusting device 40 is disposed on the first adjusting part 31 and includes a second adjusting part 41 that can move along a second direction. The flipping mechanism 50 is disposed on the second adjusting part 41 and includes at least two opposing clamping parts 51, forming a silicon rod clamping space 52 between the at least two clamping parts 51. The size of the silicon rod clamping space 52 is adjustable. At least a portion of each clamping part 51 is rotatably disposed to drive the silicon rod 10 to flip. The first direction and the second direction are arranged at an angle.

[0031] Applying the technical solution of this embodiment, when the silicon rod 10 needs to be wiped and cleaned, the silicon rod 10 is first placed on the conveying device 20 for transportation. Then, the position of the flipping mechanism 50 relative to the silicon rod 10 is adjusted by the first adjusting device 30 and the second adjusting device 40 to ensure that the silicon rod 10 can be inserted into the silicon rod clamping space 52 so that the clamping part 51 can clamp the silicon rod 10. Afterwards, the operator wipes and cleans the surface of the silicon rod 10. During the wiping process, the clamping part 51 can replace manual flipping of the silicon rod 10 to ensure that the outer peripheral surface of the silicon rod 10 can be wiped clean. This solves the problem of low wiping and cleaning efficiency and safety hazards of silicon rods in the prior art, reducing both safety risks and the labor intensity of the operators.

[0032] Optionally, the conveying device 20 is a conveyor line.

[0033] Optionally, the first direction and the second direction are set perpendicular to each other. The first direction is the X-axis direction, and the second direction is the Z-axis direction.

[0034] like Figure 1 As shown, the auxiliary flipping device also includes a centering device 60 located above the conveying device 20. The centering device 60 includes at least two telescopic portions 61 arranged opposite each other. A centering space is formed between the at least two telescopic portions 61, and the surface of each telescopic portion 61 facing the centering space is the centering surface, which is parallel to the conveying direction of the conveying device 20. This arrangement of the centering device 60 ensures that the silicon rod 10 is in the correct position before flipping, avoiding incomplete cleaning due to positional deviations. Simultaneously, this arrangement simplifies the structure of the centering device 60, making it easier to manufacture and implement, thus reducing the manufacturing cost and difficulty of the centering device 60.

[0035] In this embodiment, there are two telescopic parts 61, which are arranged opposite each other to form a centering space. The centering device 60 also includes a fourth driving device, which is drivenly connected to both telescopic parts 61 to drive them to move toward or away from each other, thereby adjusting the size of the centering space and centering silicon rods 10 of different sizes. In this way, the use of the centering device 60 can ensure that the silicon rod 10 is accurately centered before flipping, reducing subsequent operational errors.

[0036] like Figure 2 and Figure 3 As shown, the flipping mechanism 50 also includes a first drive device 53 and a ball screw mechanism 54. The first drive device 53 is driven by the ball screw mechanism 54 to rotate the screw of the ball screw mechanism 54. The nut of the ball screw mechanism 54 is connected to at least one clamping part 51. Thus, the ball screw mechanism 54 enables the two clamping parts 51 to move towards or away from each other, adjusting the size of the silicon rod clamping space 52, thereby making the movement of the two clamping parts 51 smoother and avoiding vibration and noise. At the same time, the above configuration simplifies the structure of the flipping mechanism 50, making it easier to manufacture and implement, and reducing the manufacturing cost and difficulty of the flipping mechanism 50.

[0037] Specifically, the first driving device 53 is a motor, which drives the screw of the ball screw mechanism 54 to convert the rotational motion of the screw into the translational motion of the nut, thereby realizing the movement of the two clamping parts 51 toward or away from each other.

[0038] like Figure 2 and Figure 3 As shown, each clamping part 51 includes a frame 511, a chuck 512, and a second driving device 513. The frame 511 has a mounting hole, and the nut of the ball screw mechanism 54 is connected to the frame 511. The chuck 512 is rotatably inserted into the mounting hole and is used to clamp the silicon rod 10. The second driving device 513 is driven by the chuck 512 to drive its rotation. This arrangement of the clamping parts 51 achieves both stable clamping of the silicon rod 10 and precise flipping operations, avoiding damage to the silicon rod or processing deviations caused by unstable clamping. Simultaneously, through precise flipping operations, multi-faceted processing of the silicon rod can be efficiently completed, improving production efficiency and product quality.

[0039] Specifically, after the two chucks 512 clamp the silicon rod 10, they simultaneously drive the silicon rod 10 to rotate, and the rotation axis of the silicon rod 10 is aligned with its center line, so as to ensure that the outer peripheral surface of the silicon rod 10 can be wiped, further improving the cleanliness of the silicon rod 10 for subsequent polishing.

[0040] like Figure 2 and Figure 3As shown, the flipping mechanism 50 also includes a first guide rail 55, and the frame 511 is slidably mounted on the first guide rail 55 along its extension direction. The extension direction of the first guide rail 55 is consistent with the extension direction of the screw of the ball screw mechanism 54. And / or, the flipping mechanism 50 also includes a bearing structure 56, which passes through a mounting hole, and a chuck 512 is disposed within the bearing structure 56 and connected to the inner ring of the bearing structure 56. Thus, the above arrangement makes the movement of each clamping part 51 and the rotation of the chuck 512 more stable, thereby avoiding vibration and noise.

[0041] In this embodiment, the flipping mechanism 50 further includes a first guide rail 55 and a bearing structure 56. The frame 511 is slidably disposed on the first guide rail 55 along the extending direction of the first guide rail 55. The bearing structure 56 passes through the mounting hole and the outer ring of the bearing structure 56 is fixedly connected to the mounting hole. The chuck 512 is disposed inside the bearing structure 56 and connected to the inner ring of the bearing structure 56.

[0042] like Figures 4 to 6 As shown, the first adjustment part 31 includes a rack structure, and the first adjustment device 30 further includes a third drive device 32 and a gear structure 33. The third drive device 32 is driven to rotate the gear structure 33. The gear structure 33 meshes with the rack structure to drive the rack structure and the second adjustment device 40 to move along a first direction. Thus, the coordinated use of the gear structure 33 and the rack structure enables the first adjustment device 30 to achieve precise linear motion. Simultaneously, the above configuration simplifies the structure of the first adjustment device 30, making it easier to manufacture and implement, thus reducing the manufacturing cost and difficulty of the first adjustment device 30.

[0043] Specifically, when performing multi-angle inspection and cleaning on silicon rod 10, the combined use of gear structure 33 and rack structure can ensure the accuracy and stability of adjustment, enabling silicon rod 10 to be precisely adjusted at the required angle, thereby improving the efficiency of inspection and cleaning, reducing surface damage to silicon rod caused by improper angle adjustment, and ensuring the surface quality and yield of silicon rod.

[0044] like Figure 7 As shown, the second adjustment part 41 includes a slider, and the second adjustment device 40 includes a second guide rail 42. The slider is slidably mounted on the second guide rail 42 along its extension direction, and the flipping mechanism 50 is mounted on the slider. This arrangement of the slider and the second guide rail 42 enables the second adjustment device 40 to achieve precise vertical adjustment of the flipping mechanism 50. Furthermore, this arrangement not only enables the second adjustment device 40 to achieve precise linear movement but also simplifies its structure, making it easier to manufacture and implement, thus reducing manufacturing costs and difficulty.

[0045] In this embodiment, the vertical adjustment function of the second adjustment device 40 can realize the flipping of silicon rods 10 at different heights, avoiding the tediousness and safety risks of manual handling, and improving the automation and safety of the production line.

[0046] like Figure 4 As shown, the first adjustment device 30 also includes a bracket 34 and a third guide rail 35. The first adjustment part 31 is mounted on the bracket 34, the third guide rail 35 is mounted on the bracket 34, and the second adjustment part 41 is slidably mounted on the third guide rail 35 along its extension direction. The auxiliary flipping device also includes a cleaning material storage box 70, which is mounted on the bracket 34. This arrangement facilitates the storage and replacement of cleaning materials, reduces production line interruptions due to insufficient or untimely replacement of cleaning materials, and improves the continuity and efficiency of the production line. Simultaneously, the above-mentioned design enhances the structural stability of the first adjustment device 30, preventing shaking that could affect the wiping operations of the workers.

[0047] In this embodiment, the conveying device 20 has a first station and a second station located downstream of the first station. The auxiliary flipping device also includes a detection device and a control module. The detection device is used to detect the position of the silicon rod 10 on the conveying device 20. The control module is electrically connected to the detection device, the conveying device 20, the centering device 60, the first adjustment device 30, and the second adjustment device 40. Specifically, when the detection device detects that the silicon rod 10 has been conveyed to the first station, the control module controls the conveying device 20 to stop running and controls the centering device 60 to start. After the centering device 60 completes the centering of the silicon rod 10, the control module controls the conveying device 20 to start. When the detection device detects that the silicon rod 10 has been conveyed to the second station, the control module controls the first adjustment device 30 and / or the second adjustment device 40 to start, thereby adjusting the position of the flipping mechanism 50.

[0048] In this embodiment, the control method described above by the control module reduces the safety risks and processing errors caused by manual operation and improves the intelligence level of the auxiliary flipping device.

[0049] Optionally, the detection device is a detection switch.

[0050] like Figure 1As shown, the auxiliary flipping device also includes a transfer line 80, a switching device 90, an image acquisition device, and an illumination device 100. The transfer line 80 is located on one side of the conveying device 20 to buffer the cleaned silicon rod 10. The switching device 90 is electrically connected to the flipping mechanism 50 to control its operating status. The image acquisition device is used to acquire the surface cleanliness of the silicon rod 10. Thus, the above-mentioned arrangement of the illumination device not only facilitates manual observation of surface dirt and scratches on the silicon rod 10 but also improves the clarity of image acquisition, ensuring accurate detection of the silicon rod's surface cleanliness.

[0051] Specifically, in the silicon rod surface quality control process, the lighting device 100 ensures that the image acquisition device can obtain a clear image of the silicon rod surface under any lighting conditions, and can also promptly detect and handle potential production problems, avoiding a large number of silicon rods being scrapped due to surface quality issues, thereby reducing production costs and improving production efficiency and economic benefits.

[0052] Optionally, the switching device 90 is a foot switch.

[0053] like Figure 1 As shown, the auxiliary tilting device also includes an oiling device 110, which can automatically lubricate the guide rail and rack structure according to a set time.

[0054] In this embodiment, the working principle of the auxiliary flipping device is as follows:

[0055] Silicon rod 10 is transported to centering device 60 via conveyor 20. A detection switch on conveyor 20 detects that silicon rod 10 has reached the first station. Conveyor 20 stops and performs centering. After centering, conveyor 20 transfers silicon rod 10 to the second station. A detection switch on conveyor 20 detects that silicon rod 10 is in position. The second adjusting device 40 descends to the picking position, and the flipping mechanism 50 clamps silicon rod 10. The second adjusting device 40 rises, and manual wiping begins. After wiping one side, the manual steps on a foot switch to rotate the flipping mechanism 50 and continue wiping. After wiping all four sides, the manual operates a button on the button box. The first adjusting device 30 transfers silicon rod 10 to the picking position on transfer line 80. The second adjusting device 40 descends to the picking position and returns to the waiting position, ending the process.

[0056] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0057] An auxiliary flipping device is used to flip silicon rods. The auxiliary flipping device includes a conveying device, a first adjusting device, a second adjusting device, and a flipping mechanism. The conveying device conveys the silicon rod. The first adjusting device includes a first adjusting part movable along a first direction. The second adjusting device is disposed on the first adjusting part and includes a second adjusting part movable along a second direction. The flipping mechanism is disposed on the second adjusting part and includes at least two opposing clamping parts, forming a silicon rod clamping space between the at least two clamping parts. The size of the silicon rod clamping space is adjustable. At least a portion of each clamping part is rotatably disposed to drive the silicon rod to flip; the first direction and the second direction are arranged at an angle. Thus, when the silicon rod needs to be wiped clean, the silicon rod is first placed on the conveying device for transport, and then the position of the flipping mechanism relative to the silicon rod is adjusted by the first and second adjusting devices to ensure that the silicon rod can extend into the silicon rod clamping space so that the clamping parts can clamp the silicon rod. Afterwards, the staff wiped and cleaned the surface of the silicon rod. During the wiping process, the clamping part could replace manual operation to flip the silicon rod to ensure that the outer peripheral surface of the silicon rod could be wiped clean. This solved the problem of low wiping and cleaning efficiency and safety hazards of existing technologies for silicon rods. It not only reduced safety risks but also reduced the labor intensity of the staff.
