Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic silicon rod cutting technology, and in particular to a photovoltaic silicon rod cutting wire bow adjustment mechanism. Background Technology
[0002] With the development of photovoltaic technology, solar energy, as a green, environmentally friendly, and renewable energy source, has been widely promoted. Monocrystalline silicon wafers used in solar cells are generally cut from silicon rods. The silicon rod cutting process requires a diamond wire cutting machine. When cutting silicon rods, a round silicon rod is typically squared to obtain a square rod, which is then cut in half to obtain a 1 / 2 square rod. The 1 / 2 square rod is then sliced to obtain silicon wafers for fabricating large-size solar cells. Traditional cutting, squaring, and edge-removing equipment uses fixed, non-adjustable guide wheels, commonly resulting in edge chipping after changing silicon rod specifications. Furthermore, current diamond multi-wire cutting machines require manual segmented cutting to control the bow height. Due to individual differences in materials of the same specifications and consumables such as diamond cutting wire, the adjusted cutting parameters can sometimes lead to unstable cutting speeds and deviations. Therefore, a fixed set of cutting parameters is not suitable for all cutting environments. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a photovoltaic silicon rod cutting wire bow adjustment mechanism. This mechanism can adjust the wire bow value of the cutting wire by simultaneously adjusting the spacing and length of the guide wheels, which greatly reduces the edge chipping problem when cutting, partially opening, and removing the edge skin.
[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: a photovoltaic silicon rod cutting wire bow adjustment mechanism, including a mounting base, connecting rod I, connecting rod II, guide wheel seats, linear rails, positive and negative threaded rods, and a spline shaft. Connecting rod I and connecting rod II are arranged parallel to each other on the mounting base. Both ends of connecting rod I and connecting rod II are connected by linear rails, and the two linear rails are perpendicular to connecting rod I and connecting rod II. Two guide wheel seats of the same specification are provided on each of the two linear rails perpendicularly connecting connecting rod I and connecting rod II. Each guide wheel seat is provided with a guide wheel. The spline shaft and the positive and negative threaded rods are arranged on the mounting base and are parallel to each other between connecting rod I and connecting rod II. The spline shaft is parallel and close to connecting rod I, and the positive and negative threaded rods are parallel and located between the spline shaft and connecting rod II.
[0005] Furthermore, the two ends of the spline shaft are located below the two guide wheel seats near the connecting rod I.
[0006] Furthermore, the splined shaft is provided with two gears, and the bottom of the two guide wheel seats near the connecting rod I is provided with racks that are adapted to the two gears on the splined shaft, and the gears on the splined shaft mesh with the racks at the bottom of the two guide wheel seats on the connecting rod I.
[0007] Furthermore, sliders are provided on connecting rod I and connecting rod II, and the sliders are connected to the linear guide.
[0008] Furthermore, a motor is provided at one end of the positive and negative threaded screw, and a synchronous pulley is provided at one end of the spline shaft, with the synchronous pulley and the motor located at the same end.
[0009] Furthermore, the synchronous pulley is connected to the motor via a synchronous belt.
[0010] Furthermore, the guide wheels on the guide wheel seat are all connected with diamond wire.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets up four guide wheel seats to cooperate with the guide wheels. The output motor provides two forces through the rotation of the positive and negative thread screws. One force realizes the adjustment of the wire bow and controls the forward and backward movement of the guide wheel seats on the wire rail. The other force controls the left and right movement of the wire rail on the connecting rod I and connecting rod II, thereby realizing the adjustment of the wire bow value of the cutting wire and greatly reducing the edge chipping problem when cutting, half-opening, and removing the edge skin.

[0015] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.
[0016] See attached document Figure 1 This embodiment includes a mounting base 1 for fixing on the equipment, connecting rods I2 and II3 arranged vertically parallel on the mounting base 1, and a splined shaft 7 and a threaded rod 6 fixed to the mounting base 1 and arranged parallel to each other between connecting rods I2 and II3. The splined shaft 7 is close to connecting rod I2, and the threaded rod 6 is located between the splined shaft 7 and connecting rod II3. (See attached figure.) Figure 2 Since mounting bracket 1 is installed on the wire cutting equipment, therefore... Figure 2 To identify mounting base 1, two sliders 11 are provided on both connecting rod I2 and connecting rod II3. The two ends of connecting rod I2 and connecting rod II3 are connected by linear guides 5 of the same specification, and the two linear guides 5 are respectively set on the sliders 11 on connecting rod I2 and connecting rod II3, so that the linear guides 5 can move left and right on connecting rod I2 and connecting rod II3 through the sliders 11. Four guide wheel seats 4 of the same specification are provided at the upper and lower ends of the two linear guides 5, and guide wheels 8 for connecting diamond wire 14 are provided on the top of the four guide wheel seats 4. At the same time, racks are provided at the bottom of the two guide wheel seats 4 near connecting rod I2, and the flower The key shaft 7 is located below the two guide wheel seats 4 near the connecting rod I2, and two gears 9 are provided on the spline shaft 7. The two gears 9 mesh with the racks at the bottom of the two guide wheel seats 4 near the connecting rod I2. One end of the positive and negative threaded rod 6 is provided with a motor 11 as a power output, and one end of the spline shaft 7 is provided with a synchronous pulley 12. The synchronous pulley 12 on the spline shaft 7 and the motor 11 on the positive and negative threaded rod 6 are located at the same end. Then, the synchronous pulley 12 and the motor 11 are connected by a synchronous belt 13, which connects the spline shaft 7 and the positive and negative threaded rod 6. The motor 11 on the positive and negative threaded rod 6 serves as a power source to output power.
[0017] Working principle: After mounting base 1 is installed on the cutting machine, linear guide rail 5 is connected to connecting rod I2 and connecting rod II3. The four guide wheel seats 4 located on the two linear guide rails 5 can be adjusted by moving back and forth on the linear guide rails 5, and can also move left and right between connecting rod I2 and connecting rod II3 by relying on slider 11. When the equipment needs to change product specifications, the motor 11 drives the positive and negative threaded rods 6 to rotate. The positive and negative threaded rods 6 and the synchronous pulley 12 divide the power into two groups through the synchronous belt. The first group of force rotates the positive and negative threaded rods 6, driving the two guide wheel seats 4 near the connecting rod II3 to achieve left and right centering adjustment; the second group of force drives the spline shaft 7 to rotate, which in turn drives the two guide wheel seats 4 near the connecting rod I2 to adjust back and forth through the meshing of gear 9 with the rack, ultimately adjusting the bow value of the cutting line.
