[0018] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0019] like Figure 1 and 2As shown, a silicon rod inspection and conveying device comprises a frame 1, a frame slidably connected to the frame 1, two opposite T-shaped slides 3 slidably connected to the frame, the opposite ends of the two T-shaped slides 3 are respectively rotatably connected to chucks 31, and the rotation center axes of the two chucks 31 are collinear; one of the chucks 31 is connected to a rotation drive assembly 4 for driving it to rotate; the frame is connected to a first drive mechanism 5 for driving it to move back and forth in a first direction; the two T-shaped slides 3 are connected to a second drive mechanism 6 for driving them to move relative to or toward each other in the first direction. The first direction is consistent with the length direction of the silicon rod 100 in the inspection state.

[0020] Specifically, the frame is a square frame, which is slidably connected to the frame 1 through two slide rails arranged in parallel with the first direction, and there is enough space in the middle of the frame for arranging the detection units distributed in an annular manner. Limit blocks 11 are arranged at both ends of the frame 1 for slidingly limiting the frame.

[0021] In the silicon rod inspection and conveying device, the two clamps 31 move toward each other under the drive of the second driving mechanism 6, so as to clamp the silicon rod 100 between the two clamps 31. The clamping surfaces of the two clamps 31 are planes, which are in contact with the two end surfaces of the silicon rod 100 respectively.

[0022] In this embodiment, the second driving mechanism 6 includes two first screw rods 61 arranged in parallel with the first direction, one end of the first screw rod 61 is coaxially connected to the second screw rod 62 through the second connecting shaft 63, the first screw rod 61 and the second screw rod 62 are both rotatably connected to the frame and have opposite thread directions; the first screw rod 61 is threaded with a first nut, the second screw rod 62 is threaded with a second nut, the two first nuts are connected to one of the T-shaped slides 3, and the two second nuts are connected to the other T-shaped slide 3; the other end of the first screw rod 61 is connected to a second right-angle steering gear 64, and the two second right-angle steering gears 64 are connected through a third connecting shaft 65; the third connecting shaft 65 is connected to a second motor 67 through a second reducer 66. Further, the second connecting shaft 63 is rotatably connected to the frame through at least one bearing and a bearing seat.

[0023] When in use, the second motor 67 provides power and transmits the power to the third connecting shaft 65 through the second reducer 66. The third connecting shaft 65 transmits the power to the two first screw rods 61 through the two second right-angle steering gears 64, causing the two first screw rods 61 to rotate relative to the frame, thereby driving the two T-shaped slides 3 to move toward or away from each other, so that the two chucks 31 clamp the silicon rod 100 to be inspected or the two chucks 31 release the clamping of the silicon rod 100.

[0024] In the silicon rod detection and conveying device, the driving end of the rotation drive assembly 4 is coaxially connected to the chuck 31 through the fourth connecting shaft. The fourth connecting shaft is coaxially connected with a first light shielding sheet 71, and a notch is provided on the side of the first light shielding sheet 71; a first photoelectric switch 72 is provided on the T-shaped slide 3, and the edge of the first light shielding sheet 71 is located in the U-shaped groove of the first photoelectric switch 72. By providing the first photoelectric switch 72 and the first light shielding sheet 71, the silicon rod 100 can be accurately rotated and positioned, so as to accurately rotate the side of the silicon rod with the best surface quality detected to the top.

[0025] In this embodiment, the rotary drive assembly 4 includes a servo motor 41 and a rotary reducer 42 . The output end of the servo motor 41 is connected to the fourth connecting shaft through the rotary reducer 42 .

[0026] In the silicon rod detection and conveying device, the first driving mechanism 5 includes a first connecting shaft 51 arranged along a vertical first direction and rotatably connected to the frame, and the first connecting shaft 51 is connected to a first motor 53 through a first reducer 52; both ends of the first connecting shaft 51 are transmission-connected to gears 55 through a first right-angle commutator 54, and the gear 55 is meshingly connected to a rack 56, and the two racks 56 are connected to the frame 1 along the first direction.

[0027] When in use, the first motor 53 provides power and transmits the power to the first connecting shaft 51 through the first reducer 52. The first connecting shaft 51 transmits the power to the gear 55 through the two first right-angle commutators 54. The two gears 55 are meshed with the two racks 56 to drive the frame to move in the first direction relative to the frame 1, so that the frame moves in the first direction relative to the frame 1, thereby realizing that the frame reaches the loading position, the detection position and the unloading position in sequence, and returns to the loading position from the unloading position.

[0028] Among them, a plurality of second photoelectric switches 8 are arranged on the frame 1 along the first direction, and the frame is connected with a second light shielding sheet for triggering each second photoelectric switch 8. In this embodiment, three groups of second photoelectric switches 8 are arranged, and when the second light shielding sheet triggers the first group of second photoelectric switches 8, it indicates that the frame has moved to the loading position and can clamp the silicon rod 100 to be detected; when the second light shielding sheet triggers the second group of second photoelectric switches 8, it indicates that the frame has moved to the detection position and can detect the silicon rod 100; when the second light shielding sheet triggers the third group of second photoelectric switches 8, it indicates that the frame has moved to the unloading position and can take away the silicon rod 100.

[0029] The utility model is a silicon rod detection and conveying device, and its working process is:

[0030] When the frame is in the initial position (loading position), the silicon rod 100 to be inspected is moved between the two chucks 31; the second driving mechanism 6 is used to drive the two T-shaped slides 3 to move toward each other, so that the two chucks 31 clamp the silicon rod 100; the first driving mechanism 5 is used to drive the frame to move forward, so that the frame moves to the detection position, so that the detection unit can perform all-round detection on the silicon rod 100; after the detection is completed, the first driving mechanism 5 is used to drive the frame to continue to move forward, so that the frame moves to the unloading position; the rotary drive assembly 4 drives the two chucks 31 and the clamped silicon rod 100 to rotate, so that the side of the silicon rod with the best surface quality rotates to the top; after the unloading robot clamps the fixed silicon rod 100, the second driving mechanism 6 is used to drive the two T-shaped slides 3 to move away from each other, so that the two chucks 31 release the clamping of the silicon rod 100, so that the unloading robot can take away the silicon rod 100; the first driving mechanism 5 is used to drive the frame to move backward to the initial position (loading position) to facilitate the next round of silicon rod detection and transportation.

[0031] The silicon rod detection and conveying device realizes the suspended fixation of the silicon rod 100, avoids the obstruction of all sides and edges of the silicon rod 100, facilitates the detection unit to perform all-round detection of the silicon rod 100, and is very convenient for loading and unloading.
