DETAILED DESCRIPTION

[0032] The following description will be made in conjunction with the accompanying drawings. Figs. 1-3 The application is further described in detail.

[0033] The application discloses a silicon core rod rotating clamping device.

[0034] A silicon core rod rotating clamping device includes a placement table 1, a support seat 2 and a lower pressing frame 3. The support seat 2 is provided with a plurality of rotating units 4 and rotating power sources in the vertical direction of the length of the silicon core rod 7. The lower pressing frame 3 is located above the rotating unit 4 and moves in the vertical direction through the adjusting unit 5.

[0035] During the detection of the silicon core rod 7, the workers place a plurality of silicon core rods 7 on the rotating unit 4 of the support seat 2, and the rotating unit 4 is responsible for supporting the silicon core rod 7. Then, the lower pressing frame 3 is controlled to move towards the silicon core rod 7 and contact it through the adjusting unit 5. The rotating power source drives the silicon core rod 7 rotating rod to rotate through the rotating unit 4, so that the workers can check a plurality of silicon core rods 7 at the same time during the rotating process, thereby improving the checking efficiency. At the same time, the silicon core rod 7 is placed on the rotating unit 4, which reduces the risk of damage to the silicon core rod 7 during the inspection process.

[0036] The support seat 2 is composed of a reference support seat 21 and an adjusting support seat 22, both of which are installed on the placement table 1. The adjusting support seat 22 is close to or away from the reference support seat 21 along a specific route through the adjusting power source 6. The adjusting support seat 22 is at least one pair, and each pair is distributed on both sides of the reference support seat 21. According to the length of the silicon core rod 7, the adjusting support seat 22 moves on the placement table 1 through the adjusting power source 6 to change the distance between the reference support seat 21 to adapt to silicon core rods 7 of different lengths.

[0037] The adjusting power source 6 includes a threaded rod 61 and an adjusting motor, and the adjusting support seat 22 and the placement table 1 are in sliding fit. The threaded rod 61 passes through the reference support seat 21 and the adjusting support seat 22, and is in rotating fit with the reference support seat 21 and in threaded connection with the adjusting support seat 22. The threaded rod 61 is provided with two sections of threads with opposite rotation directions, and each section of thread corresponds to a pair of adjusting support seats 22. The adjusting motor drives the threaded rod 61 to rotate, so that each pair of adjusting support seats 22 can be close to or away from the reference support seat 21 synchronously.

[0038] The rotating unit 4 comprises at least a pair of rotating rollers 41 which are rotationally connected with the reference support base 21, and adjacent rotating rollers 41 are connected by a transmission belt 42. When the rotating rollers 41 rotate, the other rotating rollers 41 are driven to rotate synchronously by the transmission belt 42, thereby improving the convenience of driving multiple rotating rollers 41 to rotate. The silicon rod 7 is placed on the pair of rotating rollers 41, and the two rotating rollers 41 cooperatively support the silicon rod 7, thereby enhancing the adaptability to silicon rods 7 of different sizes.

[0039] The rotating power source comprises a rotating motor which is rotationally connected with the rotating rollers 41 on the reference support base 21, and drives the middle part of the silicon rod 7 to rotate through the rotating rollers 41, thereby reducing the torsional force on the silicon rod 7 and reducing the possibility of damage to the silicon rod 7.

[0040] The bottom of the pressing frame 3 is provided with a plurality of rotating rollers 31 which are arranged in a direction perpendicular to the length direction of the silicon rod 7, and the rotating rollers 31 are rotationally connected with the silicon rod 7, thereby pressing the silicon rod 7 while reducing the rotating resistance of the silicon rod 7.

[0041] The adjusting unit 5 comprises a guide cylinder 51 and a mounting rod 52, one end of the guide cylinder 51 is arranged on the adjusting support base 22, one end of the mounting rod 52 is arranged in the guide cylinder 51 and is connected with the guide cylinder 51, and the other end of the mounting rod 52 is arranged on the pressing frame 3. The pressing frame 3 presses the silicon rod 7 on the rotating rollers 41 under the action of its own gravity, thereby improving the convenience of pressing the silicon rod 7 and enhancing the adaptability to different silicon rods 7.

[0042] The implementation principle of the silicon rod rotating clamping device is as follows. First, the rotating unit 4 and the rotating power source on the support base 2 are used to realize the stable support and rotation of the silicon rod 7. The rotating unit 4 comprises at least a pair of rotating rollers 41 which are driven to rotate synchronously by a transmission belt 42, and the rotating unit 4 drives the middle part of the silicon rod 7 to rotate, thereby reducing the torsional force on the silicon rod 7 and reducing the possibility of damage to the silicon rod 7. Second, the adjusting support base 22 can be moved on the placement table 1 by the adjusting power source 6 according to the length of the silicon rod 7, and the distance between the adjusting support base 22 and the reference support base 21 is changed to adapt to silicon rods 7 of different lengths. The adjusting power source 6 comprises a threaded rod 61 and an adjusting motor, the threaded rod 61 is provided with two sections of threads with opposite directions, so that each pair of adjusting support bases 22 can be driven to approach or move away from the reference support base 21 synchronously. In addition, the bottom of the pressing frame 3 is provided with rotating rollers 31 which are rotationally connected with the silicon rod 7, thereby pressing the silicon rod 7 while reducing the rotating resistance of the silicon rod 7. Finally, the adjusting unit 5 comprises a guide cylinder 51 and a mounting rod 52, and the pressing frame 3 presses the silicon rod 7 on the rotating rollers 41 under the action of its own gravity, thereby improving the convenience of pressing the silicon rod 7 and enhancing the adaptability to different silicon rods 7.
