As the key raw material in these industries, the processing quality of silicon rods directly affects the performance and reliability of the final product. In the processing of silicon rods, precise positioning and efficient and stable clamping technology are key factors to ensure production efficiency and product quality.

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application (for the convenience of description and understanding, the following is Figure 2 All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0017] See also Figure 1-3 The present application provides a technical solution: a clamping and fixing device for transporting silicon rods, comprising an upper bracket, on which a sliding guide groove is provided, on which a sliding guide seat 2 is slidably provided, and on which a clamping device is provided.

[0018] The sliding guide groove realizes precise adjustment of the clamping device in the horizontal direction. The sliding guide groove is located on the main support plate 4 and has a smooth guiding structure inside, which can ensure that the sliding guide seat 2 moves smoothly thereon.

[0019] Side wing plates are provided on the upper and lower sides of the sliding guide seat 2, which cooperate well with the sliding guide groove, so that the sliding guide seat 2 can be accurately and stably fine-tuned in the horizontal direction; the sliding guide seat 2 carries a clamping device, so that the clamping device can change position with the movement of the sliding guide seat, adapting to the needs of different processing positions or making subtle position adjustments to the silicon rod.

[0020] The clamping device includes a clamping motor 3, an upper connecting block 11, a vertical lead screw guide shaft 13, a lead screw connecting sleeve 14, a first hinge seat 16, a second hinge seat 17 and a bar clamp seat 15. The output end of the clamping motor 3 is provided with a vertical lead screw guide shaft 13, and the vertical lead screw guide shaft 13 is provided with a lead screw connecting sleeve 14. The two ends of the lead screw connecting sleeve 14 are connected with the first hinge seat 16. The upper end of the first hinge seat 16 is hinged with one end of the second hinge seat 17. The second hinge seat 17 is connected to both sides of the upper connecting block 11. The lower end of the first hinge seat 16 is connected with the bar clamp seat 15.

[0021] The clamping device is a component for clamping the silicon rod, and is driven by the clamping motor 3 to achieve reliable clamping and loosening of the silicon rod.

[0022] When the clamping motor 3 is started, it will output a rotational motion, and transmit the power to the vertical lead screw guide shaft 13 through the transmission structure; driving the vertical lead screw guide shaft 13 to rotate. Since the lead screw has a self-locking property, the linear motion along its axis direction can be accurately controlled during the rotation process; the lead screw connecting sleeve 14 moves up and down with the rotation of the vertical lead screw guide shaft 13, thereby driving the first articulated seat 16 to rotate; the first articulated seat 16 and the second articulated seat 17 are hinged to form a structure similar to a connecting rod mechanism, so that the linear motion of the lead screw connecting sleeve 14 can convert the opening and closing clamping action of the first articulated seat 16 and the second articulated seat 17, thereby enabling the rod clamping seat 15 to clamp the silicon rod, thereby improving the clamping efficiency.

[0023] The lower surface of the upper bracket is also provided with a displacement adjustment group for adjusting the clamping device.

[0024] The displacement adjustment group is responsible for adjusting the lateral position of the clamping device to ensure the accuracy of the clamping position.

[0025] Furthermore, the upper bracket is composed of a main support plate 4 and a side support plate 5 , and the side support plates 5 are arranged on both sides of the main support plate 4 .

[0026] The main support plate 4 is the main load-bearing component of the upper bracket, bearing the weight of the sliding guide seat 2, the displacement adjustment group and part of the clamping device, ensuring that the stability and rigidity of the overall structure can be maintained even when uneven force or impact occurs during the processing of clamping silicon rods.

[0027] The side support plate 5 plays a role of auxiliary support and connection, strengthens the overall structural strength of the upper bracket, and also provides a mounting position for installing other functional components such as the displacement drive motor 1 and the second lead screw 12.

[0028] Furthermore, a slide rail 7 is provided on the lower surface of the main support plate 4, and a connecting slide plate 9 is slidably provided on the slide rail 7, and the connecting slide plate 9 is connected to an upper connecting block 11 on the clamping device through a fastener.

[0029] Furthermore, the displacement adjustment group includes a displacement drive motor 1, a first lead screw 8, a second lead screw 12 and a lead screw intermediate connecting sleeve 10. The displacement drive motor 1 is arranged on one side of the left end side support plate 5. The output end of the displacement drive motor 1 is connected to the first lead screw 8. The lower surface of the upper bracket is connected to the lead screw intermediate connecting sleeve 10. The first lead screw 8 and the second lead screw 12 are respectively connected to both sides of the lead screw intermediate connecting sleeve 10. The installation directions of the first lead screw 8 and the second lead screw 12 are opposite.

[0030] When the displacement drive motor 1 is started, its rotation drives the first lead screw 8 to rotate, and due to the principle of the lead screw, the rotational motion is converted into linear motion. It is worth noting that although the first lead screw 8 and the second lead screw 12 are both connected to the lead screw intermediate connecting sleeve 10, the installation directions of the two are opposite; when the displacement drive motor 1 is working, it can simultaneously drive the clamping device to move to the left and right sides in the horizontal direction, realizing the function of bidirectional translation.

[0031] Furthermore, a positioning guide sleeve 6 is provided on the right end of the side support plate 5 , and the positioning guide sleeve 6 is connected to the second lead screw 12 .

[0032] When in use: First, according to the specific size of the silicon rod and the processing position requirements, the operator can accurately position the clamping device horizontally through the displacement adjustment group. Start the displacement drive motor 1, and the motor rotates to drive the first screw 8 to rotate. Due to the screw transmission principle, this rotational motion will be converted into a linear reciprocating motion of the sliding guide seat 2 on the slide rail 7, and the design of the second screw 12 in the opposite direction to the first screw 8 ensures that the clamping device can achieve bidirectional translation.

[0033] After the horizontal position of the clamping device is determined to be consistent with the length of the silicon rod, when the clamping motor 3 is working, the power outputted by the clamping motor 3 is transmitted to the screw connecting sleeve 14 via the vertical screw guide shaft 13, so that the screw connecting sleeve 14 moves up and down. After the transformation of the connecting rod mechanism composed of the first hinge seat 16 and the second hinge seat 17, the bar clamp seat 15 can be accurately closed or opened, thereby firmly clamping or releasing the silicon rod, and ensuring the stability of the clamping.

[0034] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
