[0033] During the production of single crystal silicon, it is usually necessary to align and bond one end of the silicon rods together to fix the crystal orientation, reduce material loss, improve processing efficiency, and increase the utilization rate of the silicon rods.

[0034] In the prior art, silicon rods are typically bonded together manually. During the bonding process, the surface of the silicon rod must first be cleaned to ensure it is dust-free. Then, glue is evenly applied to the end of the silicon rod. Another silicon rod is placed on top of the glued rod, and the position of the upper silicon rod is adjusted so that the two silicon rods are coaxial.

[0035] However, in the above operation process, the positions of the two silicon rods are adjusted by manual visual judgment, which cannot ensure the coaxiality of the two silicon rods, resulting in poor quality of silicon rod bonding.

[0036] In order to solve the above problems, the present application provides a rod bonding device, which places the first rod on the frame through the setting of the positioning component and the adjustment component, so that the first rod is located between the two tightening parts and the adjustment rope, and pulls the adjustment rope according to the instruction of the positioning component to drive the first rod to move to abut against the two tightening parts, thereby realizing the positioning of the first rod and obtaining the positional relationship between the first rod and the tightening parts and the adjustment rope; applies glue on the top of the first rod, adjusts the height of the tightening parts and the adjustment rope, and places the second rod on the first rod, and then pulls the adjustment rope to adjust the position of the second rod, so that the second rod moves to abut against the two tightening parts, so that the central axes of the two rods coincide, and the three-point positioning of the rods is realized through the cooperation of the two tightening parts and the adjustment rope, thereby improving the accuracy of the rod docking and thus improving the quality of the rod bonding.

[0037] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0038] This application provides a bar bonding device, referring to Figures 1 to 4 , the bar bonding device includes: a frame 100;

[0039] A positioning assembly 200 is provided on the frame 100 to locate the position of the bar;

[0040] Adjustment assembly 300, the adjustment assembly 300 includes an adjustment rope 310, two support rods 320 and two tightening members 330, the support rods 320 are set on the frame 100, the two tightening members 330 are respectively set on the two support rods 320, and are used for rod abutment, the two ends of the adjustment rope 310 are respectively connected to the two support rods 320, the adjustment rope 310 is used to be tightly attached to the side wall of the rod, and the adjustment rope 310 is contracted to move the rod toward the tightening members 330.

[0041] The two support rods 320 are fixed vertically to the edge of the frame 100, and the distance between the two support rods 320 and the middle of the frame 100 where the bar is placed is the same. This ensures that the distance between the pressing members 330 on the two support rods 320 and the bar is the same, which facilitates the abutment and positioning of the bar.

[0042] In the embodiment of the present application, the rod material is a silicon rod. In other embodiments, it can also be applied to the coaxial docking of other circular materials, which will not be elaborated here.

[0043] In this embodiment, the first silicon rod is placed on the frame 100 so that the first silicon rod is located between the two tightening members 330 and the adjusting rope 310. According to the instructions of the positioning component 200, the adjusting rope 310 is pulled to drive the first silicon rod to move to abut against the two tightening members 330 to achieve the positioning of the first silicon rod; glue is applied on the top of the first silicon rod, the height of the tightening members 330 and the adjusting rope 310 are adjusted, and the second silicon rod is placed on the first silicon rod. The adjusting rope 310 is then pulled to adjust the position of the second silicon rod so that the second silicon rod moves to abut against the two tightening members 330, so that the central axes of the two silicon rods coincide, and the three-point positioning of the silicon rods is achieved through the cooperation of the two tightening members 330 and the adjusting rope 310, thereby improving the accuracy of the silicon rod docking and thus improving the quality of the silicon rod bonding.

[0044] In some embodiments, reference Figure 1 and Figure 2 The tightening member 330 includes a push rod 331 and a mounting block 332. The mounting block 332 is passed through the support rod 320. The mounting block 332 rotates along the length direction of the support rod 320. The push rod 331 is threadedly inserted into the mounting block 332 to move the push rod 331 toward the center axis of the rod.

[0045] The mounting block 332 is inserted into the support rod 320 and can slide along the length of the support rod 320 and rotate around the support rod 320. During use, the upper and lower silicon rods can be positioned by sliding the mounting block 332; the angle of the top rod 331 can be adjusted by rotating the mounting block 332 so that the top rod 331 faces the center of the silicon rod, thereby cooperating with the adjustment rope 310 to adjust the position of the silicon rod.

[0046] The top rod 331 is a screw threaded into the mounting block 332. By rotating the top rod 331, the length of the top rod 331 extending beyond the mounting block 332 can be adjusted to accommodate silicon rods of varying diameters. Extending the top rods 331 on the two support rods 320 to the same length and cooperating with the adjustment rope 310 achieves three-point positioning of the silicon rod. Adjustment is achieved by tightening the adjustment rope 310, which is flexible, increasing the contact area with the silicon rod and minimizing damage.

[0047] Furthermore, a rubber block is provided at the end of the push rod 331 to abut against the silicon rod, thereby preventing the hard push rod 331 from causing the silicon rod surface to dent. Furthermore, the rubber block can be configured as an arc block to further increase the contact area between the rubber block and the silicon rod, thereby improving the protection of the silicon rod.

[0048] In some embodiments, reference Figure 1and Figure 2 The tightening member 330 further includes a fixing screw 333 , which is threadedly disposed on the mounting block 332 and abuts against the support rod 320 .

[0049] The fixing screw 333 is threaded onto the mounting block 332 and passes through the mounting block 332 to abut against the support rod 320. When the mounting block 332 needs to be moved, the fixing screw 333 is rotated to separate the fixing screw 333 from the support rod 320, thereby adjusting the position and angle of the mounting block 332. Once the mounting block 332 is adjusted into position, the fixing screw 333 is rotated to tighten the fixing screw 333 against the support rod 320, thereby securing the mounting block 332. This prevents the push rod 331 from moving during the silicon rod position adjustment process.

[0050] In some embodiments, reference Figure 3 and Figure 4 The positioning assembly 200 includes an adjusting member 210 and at least three infrared emitters 220. The adjusting member 210 is set on the frame 100, and the infrared emitter 220 is set on the adjusting member 210. The adjusting member 210 is used to adjust the position of the infrared emitter 220 so that the infrared emitters 220 are all located on the same circumference. The infrared emitter 220 emits infrared rays in a vertical direction, and the infrared rays are used to coincide with the side wall of the bar.

[0051] For example, four infrared emitters 220 are provided. These four infrared emitters 220 are mounted on the same circumference. When placing the bottom silicon rod, the sidewalls of the silicon rod and the infrared rays overlap, thereby ensuring proper positioning of the bottom silicon rod. During placement of the upper silicon rod, the overlap between the infrared rays and the sidewalls of the silicon rods can be used to determine the position of the silicon rods, improving the coaxiality of the two silicon rods and further enhancing the bonding quality of the silicon rods.

[0052] In some embodiments, a mounting plate 110 is provided on the frame 100 , and a placement slot 111 is provided on the mounting plate 110 for placing bar materials.

[0053] The mounting groove is a circular groove, and the diameter of the mounting groove is larger than the diameter of the silicon rod, so that silicon rods of different diameters can be easily placed, thereby improving the applicability of the device.

[0054] In some embodiments, the adjusting member 210 includes a plurality of adjusting blocks 211, and a plurality of adjusting slots 112 are opened on the mounting plate 110. The extension lines of the adjusting slots 112 intersect at the center of the placement slot 111. The adjusting blocks 211 are slidably set in the adjusting slots 112, and the infrared emitters 220 are correspondingly set on the adjusting blocks 211.

[0055] Adjustment slot 112 is located on the diameter of placement slot 111. Adjustment blocks 211 are provided in a one-to-one correspondence with infrared emitters 220, and adjustment slot 112 and adjustment blocks 211 are provided in a one-to-one correspondence. Adjustment slot 112 is located at the bottom of the mounting slot, and mounting block 332 and infrared emitter 220 are embedded within adjustment slot 112, preventing mounting block 332 from interfering with the placement of the silicon rods.

[0056] In some embodiments, a fixing bolt 212 is provided on the adjustment block 211 . The fixing bolt 212 is threadedly passed through the adjustment block 211 and abuts against the bottom wall of the adjustment slot 112 .

[0057] The fixing bolt 212 is threadedly mounted on the adjustment block 211 and is completely embedded in the adjustment block 211. The adjustment slot 112 is a dovetail slot, and the adjustment block 211 is a dovetail block adapted to the adjustment slot 112. The fixing bolt 212 passes through the adjustment block 211 and abuts against the bottom wall of the adjustment slot 112, thereby securing the adjustment block 211.

[0058] Furthermore, a plurality of scales 113 are embedded in the mounting plate 110. The scales 113 are arranged in a one-to-one correspondence with the adjustment slots 112, and the scales of the scales 113 record the distance between the adjustment block 211 in the adjustment slot 112 and the circular placement slot 111, so that the plurality of adjustment blocks 211 can be adjusted to the same circumference.

[0059] In some embodiments, an upper platform 120 is provided on the frame 100 , and a connecting hole for the rod to pass through is opened on the upper platform 120 .

[0060] The provision of the upper platform 120 is beneficial for protecting the silicon rods, reducing the possibility of the silicon rods falling over, and improving the protection effect of the silicon rods.

[0061] In some embodiments, a connecting block 311 is slidably provided on each of the support rods 320 , and both ends of the adjusting rope 310 are respectively slidably passed through the two connecting blocks 311 to adjust the length of the adjusting rope 310 .

[0062] The connecting block 311 is slidably mounted on the supporting rod 320 , and both ends of the adjusting rope 310 are respectively passed through the two connecting blocks 311 . By pulling the adjusting rope 310 at both ends of the connecting block 311 , the position of the silicon rod in the adjusting rope 310 can be adjusted.

[0063] In some embodiments, a limit block 312 is provided at the end of the adjustment rope 310 , and the limit block 312 is used to abut against the connecting block 311 to limit the adjustment rope 310 from moving out of the connecting block 311 .

[0064] The stopper 312 is fixed to the end of the adjustment rope 310, preventing the adjustment rope 310 from moving out of the connecting block 311. During use, simply tighten one end of the adjustment rope 310, bring the stopper 312 at the end of the adjustment rope 310 into contact with the connecting block 311, and then continue to tighten the adjustment rope 310, which will similarly move the silicon rod and adjust its position. Furthermore, the friction between the connecting block 311 and the support rod 320 is greater than or equal to the weight of the connecting block 311 and the adjustment rope 310, preventing the connecting block 311 from sliding freely.

[0065] The present application provides a rod bonding device, which places a first silicon rod on a frame 100 so that the first silicon rod is located between two top tightening members 330 and an adjusting rope 310, and pulls the adjusting rope 310 according to the instruction of the positioning component 200 to drive the first silicon rod to move and abut against the two top tightening members 330, thereby realizing the positioning of the first silicon rod and obtaining the positional relationship between the first silicon rod and the top tightening members 330 and the adjusting rope 310; applies glue on the top of the first silicon rod, adjusts the height of the top tightening members 330 and the adjusting rope 310, and places the second silicon rod on the first silicon rod, and then pulls the adjusting rope 310 to adjust the position of the second silicon rod so that the second silicon rod moves to abut against the two top tightening members 330, thereby making the central axes of the two silicon rods coincide, and realizes three-point positioning of the silicon rods through the cooperation of the two top tightening members 330 and the adjusting rope 310, thereby improving the accuracy of silicon rod docking and thus improving the quality of silicon rod bonding.
