Description

Technical Field

[0001] This utility model relates to the field of polycrystalline silicon production technology, and in particular to a silicon rod bonding machine that facilitates alignment. Background Technology

[0002] The current method for preparing square silicon cores is to first use the Czochralski method to pull silicon rods with a diameter of 200-300mm and a length of 1.5-4m, and then use a cutting machine to cut them into square silicon cores of appropriate sizes (10×10mm, 15×15mm or 18×18mm). The cutting of the crystal rods is carried out on a vertical cutting machine, so the crystal rods need to be suspended on the cutting machine.

[0003] The vertical ingot cutting machine is similar to an ultra-long silicon core cutting machine disclosed in Chinese patent document CN110216802A. It includes a housing, a base inside the housing, a lifting mechanism at the front of the base, a column at the rear of the base, a fixed frame at the top of the column, and an L-shaped bracket bent forward at the bottom of the fixed frame. A clamping device is located at the front end of the L-shaped bracket. A crystal substrate is suspended on the fixed frame. A cutting guide wheel assembly is mounted on the lifting mechanism. Below the cutting guide wheel assembly are a guide wheel and a transition wheel, respectively mounted on the bottom surface of the housing via a guide wheel bracket and a transition wheel bracket. It is evident that the ingot mounting method requires fixing the ingot to the crystal substrate and suspending it on the vertical cutting machine for cutting using diamond wire.

[0004] The crystal rod and the crystal base are bonded together with adhesive. When the crystal base is installed, the upper middle part of the crystal rod needs to be aligned with the lower middle part of the crystal base. Otherwise, when the crystal rod is suspended on the vertical cutting machine, the verticality of the crystal rod needs to be adjusted repeatedly to ensure that the diamond wire is cut along the length of the crystal rod when cutting vertically, thus ensuring the yield of silicon cores cut from a single crystal rod.

[0005] The bonding of silicon rods to crystal substrates is carried out on a rod bonding machine. Existing rod bonding machines do not have a structure for alignment, making it difficult to align the silicon rods and crystal substrates during the bonding process. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5As shown, a silicon rod bonding machine for easy alignment includes a base 1, a turntable 2 rotatably connected to the upper side of the base 1 near the right side, a crystal seat 3 fixedly connected to the upper side of the turntable 2 near the left side, four rectangularly distributed adjustment mechanisms 4 slidably connected to the upper side of the turntable 2, stabilizing mechanisms 5 fixedly connected to the front and rear sides of the turntable 2, two front and rear traction seats 6 fixedly connected to the front and rear sides of the turntable 2 near the left side, and an insertion plate 7 fixedly connected to the left side of the turntable 2.

[0027] The adjustment mechanism 4 includes a slide plate 41, the lower side of which is slidably connected to the upper side of the turntable 2. A first telescopic rod 42 is rotatably connected to the upper side of the slide plate 41 near the outer side of the turntable 2. A second telescopic rod 43 is fixedly connected to the upper side of the slide plate 41 near the middle of the upper side of the turntable 2. A mounting plate 44 is rotatably connected to the upper side of the first telescopic rod 42 and the second telescopic rod 43.

[0028] It should be noted that the traction device connected to the traction seat 6 can drive the turntable 2 to rotate on the base 1. Then, the vertically movable insertion rod device is inserted into the insertion plate 7 to keep the turntable 2 in a vertical state. The first telescopic rod 42 and the second telescopic rod 43 are electric push rods that control the height and posture of the mounting plate 44 by controlling their own length.

[0029] like Figure 3 As shown, laser rangefinders 45 are fixedly connected to the left and right sides of the mounting plate 44.

[0030] It should be noted that the laser rangefinder 45 emits a laser beam perpendicular to the upper surface of the mounting plate 44. Multiple laser beams are used to irradiate the crystal rod to detect the diameter of the crystal rod.

[0031] like Figure 3 As shown, a third telescopic rod 46 is fixedly connected to the upper middle part of the slide plate 41, and the outer side of the third telescopic rod 46 is fixedly connected to the upper side of the turntable 2.

[0032] It should be noted that the third telescopic rod 46 is an electric push rod that can drive the slide plate 41 to move back and forth, so that when the crystal rod is being cut, the mounting plate 44 can be moved away from the crystal rod and will not affect the cutting operation.

[0033] like Figure 3 As shown, the upper side of the mounting plate 44 is provided with several evenly distributed needle rollers.

[0034] It should be noted that the needle roller is used to reduce the friction between the crystal rod and the mounting plate 44. After the mounting plate 44 adjusts the position of the crystal rod, it directly pushes the crystal rod to fix it.

[0035] like Figure 4 , Figure 5As shown, the stabilizing mechanism 5 includes a fourth telescopic rod 51. The outer sides of the fourth telescopic rod 51 are fixedly connected to the front and rear sides of the turntable 2, and there are two fourth telescopic rods 51 distributed in the front and rear. Rotators 52 are fixedly connected to the right side of each of the two fourth telescopic rods 51. Connecting rods 53 are fixedly connected to the output ends of the two rotating rods 52. A support plate 54 is fixedly connected to the left side of the connecting rod 53 located on the rear side near the front side. A retaining sleeve 55 is fixedly connected to the right side of the support plate 54 near the front side.

[0036] It should be noted that the fourth telescopic rod 51 is an electric push rod that can drive the rotary unit 52 to move left and right. The rotary unit 52 can drive the connecting rod 53 to rotate. During operation, the two connecting rods 53 rotate close to each other, so that the rear end of the front connecting rod 53 is inserted into the sleeve 55. This allows the two fourth telescopic rods 51 to jointly drive the support plate 54, so that the support plate 54 abuts against the right side of the crystal rod. This stabilizes the crystal rod during the rotation of the turntable 2, avoiding the problem that the adhesive between the crystal seat 3 and the crystal rod may not be completely dry and cause the crystal rod to fall off if only the mounting plate 44 is used to support the crystal rod. During cutting, the rotary unit 52 drives the connecting rods 53 to move away from each other, so that the connecting rods 53 and the support plate 54 do not affect the cutting operation.

[0037] like Figure 4 , Figure 5 As shown, two sliding platforms 56 are slidably connected to the upper side of the turntable 2 near the right side. Several horizontally distributed fifth telescopic rods 57 are fixedly connected to the lower side of each of the two sliding platforms 56. The outer side of the fifth telescopic rods 57 is fixedly connected to the inner side of the turntable 2.

[0038] It should be noted that the fifth telescopic rod 57 is an electric push rod that can drive the slide table 56 to move back and forth. When the slide tables 56 are close to each other, they can be inserted into the front and rear sliding grooves on the bottom wall of the support plate 54, thereby making the movement of the support plate 54 more stable.

[0039] like Figure 5 As shown, a rubber pad is fixedly connected to the left side of the support plate 54.

[0040] It should be noted that the rubber pad is used to reduce the wear of the crystal ingot on the support plate 54. At the same time, the rubber pad is fixed to the support plate 54 with glue, and can be quickly removed and replaced after it wears out.

[0041] The working principle of this utility model is as follows: First, the first telescopic rod 42 and the second telescopic rod 43 are electric push rods. By controlling their own length, they control the height and posture of the mounting plate 44. The laser rangefinder 45 emits a laser beam perpendicular to the upper surface of the mounting plate 44. Multiple laser beams are used to irradiate the crystal rod to detect its diameter. The crystal rod is directly placed between the two mounting plates 44. The diameter of the crystal rod is detected by the laser rangefinder 45. Then, the height of the crystal rod is adjusted by the first telescopic rod 42 and the second telescopic rod 43 to achieve automatic alignment, facilitating the installation of the crystal rod. Finally, the traction device connected to the traction seat 6 can drive the turntable 2 to rotate on the base 1. Then, the vertically movable insertion rod device is inserted into the insertion plate 7 to keep the turntable 2 vertical. The fourth telescopic rod 51 is an electric push rod that can drive the rotator 52 to move left and right. The rotator 52 can drive the connecting rod 53 to rotate. During operation, the two connecting rods 53 rotate close to each other. The rear end of the front connecting rod 53 is inserted into the sleeve 55, allowing the two fourth telescopic rods 51 to jointly drive the support plate 54. The support plate 54 then presses against the right side of the crystal rod, stabilizing the crystal rod during the rotation of the turntable 2. This avoids the problem of the crystal rod falling off if the adhesive between the crystal seat 3 and the crystal rod is not completely dried due to the only support plate 44 supporting the crystal rod. During cutting, the rotator 52 drives the connecting rods 53 to move away from each other, preventing the connecting rods 53 and the support plate 54 from affecting the cutting operation. The fifth telescopic rod 57 is an electric push rod that can drive the slide 56 to move back and forth. When the slides 56 are close together, they can be inserted into the front and rear sliding grooves on the bottom wall of the support plate 54, making the movement of the support plate 54 more stable. The support plate 54 supports the crystal rod, allowing the turntable 2 to be placed horizontally for easy crystal rod fixation. After the crystal rod is fixed, the turntable 2 is rotated to make it vertical, avoiding the difficulty of installation and unstable operation caused by directly fixing it in a vertical position.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
