Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic glass production, relates to coaxiality alignment of coating equipment in a photovoltaic glass production line, and particularly relates to a reducer base for assisting in coaxiality alignment. Background Art

[0002] The transmittance of photovoltaic ultra-white panel glass has become an important factor in photoelectric conversion. The coating equipment is a device that evenly coats one or two layers of dielectric solution, namely coating liquid, on the surface of ultra-white rolled glass to effectively improve the transmittance of light waves. The yield rate of coated glass directly affects the cost of photovoltaic glass. The vibration of the coating equipment will cause defects such as stripes, curtain prints, and head prints on the surface of the coated glass, which directly affects the yield rate of the coated glass. After observation and analysis, the vibration of the coating roller is relatively frequent and quite representative. The belt conveyor active roller and the liquid metering roller have very similar installation structures and driving methods to the coating roller, but they are not replaced as frequently as the coating roller. The coating roller is supported by bearings at both ends, the reducer is driven by a coupling, and the roller is wrapped with a layer of PU glue with relevant requirements. The glue surface carries the coating liquid and is evenly coated on the glass surface as it rotates. The coating roller of the PU rubber cylindrical surface needs to be replaced frequently due to wear, gelation, accidental scratches, etc. During the disassembly and installation of the reducer, the reducer mounting base will move downward due to the impact force generated by placing the reducer. The coaxiality between the reducer and the coating roller deteriorates beyond the correction range of the coupling, resulting in vibration and affecting the product yield.

[0003] In order to address the root cause of the vibration, measures need to be taken to avoid the impact force generated by placing the reducer as much as possible, while reducing the labor intensity of disassembling and installing the reducer; even if errors occur, they can be easily and quickly detected and adjusted to restore the coaxiality requirements between the coating roller and the reducer.

[0008] The vertical plate is provided with a long hole arranged in the vertical direction, and a flat plate with a threaded hole is protruded outwardly from the upper end of the vertical plate, and the lower end of the threaded hole is suspended.

The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the utility model without substantially changing the technical content.

[0025] The utility model provides a reducer base for assisting in aligning the coaxiality, such as Figures 1 to 6 shown.

[0026] A reducer base for assisting in aligning the coaxiality, the reducer base 8 is equipped with a coating roller reducer 6 and includes a bottom plate 4, a vertical plate 1 fixed on the bottom plate 4 in the vertical direction, and a diagonal plate 3 supported and fixed therebetween; the bottom plate 4 is provided with a fixed long hole 41 arranged along the axial direction to facilitate the forward and backward movement of the reducer; the vertical plate 1 is provided with a processed long hole 42 arranged along the vertical direction to facilitate up and down adjustment; and the upper end of the vertical plate 1 is also provided with a flat plate 2 with a threaded hole protruding outwardly, and the lower end of the threaded hole 43 is suspended in the air, which can realize up and down adjustment and is convenient for precise adjustment.

[0027] The bottom plate 4 is extended along the output shaft direction of the reducer, and at least one group of fixed long holes 41 is provided along the axial direction, and each group of fixed long holes is fixedly provided on both sides of the bottom plate; in this embodiment, two groups of fixed long holes are provided along the axial direction; when replacing the coating roller, the reducer is pulled outward without being removed, and the reducer is pushed forward when installing the coupling, so as to avoid the downward impact force when installing the reducer.

[0028] The vertical plate 1 and the bottom plate 4 are 90° apart and are connected by bolts and then welded, while the inclined plate is welded and fixed on the outside of the vertical plate and the bottom plate to prevent the reducer bottom plate from bending downward and deforming, which would affect the coaxiality accuracy.

[0029] When vibration occurs, remove the reducer, place the height gauge base and the reducer base on the same plane, and measure the height of the cylindrical surface on the reducer output shaft. This height and the output shaft diameter are used as the basis for calculating the centerline height of the reducer output shaft.

[0030] Based on the fact that the centerline height of the reducer output shaft is coaxial with the centerline height of the coating roller, plus half of the diameter of the coating roller mounting coupling shaft head, the theoretical height from the bottom plate of the reducer base to the cylindrical surface on the coating roller mounting coupling shaft head is adjusted based on this theoretical height.

[0031] When the scale is higher than the cylindrical surface on the shaft head of the coating roller coupling, adjust the reducer base downward to a suitable position through the fixing bolts 11 on the vertical plate 1; when the scale is lower than the cylindrical surface on the shaft head of the coating roller coupling, adjust the reducer base upward to a suitable position through the bolts on the vertical plate.

[0032] Adjust the scale height of the height gauge 5 to the above theoretical height, tighten the fixing bolts 11 on the vertical plate to an appropriate degree, place the base of the height gauge on the bottom plate of the reducer base 8, and measure the height of the cylindrical surface on the mounting shaft head of the coating roller coupling. If the base is high, adjust it downward, otherwise adjust it upward.

[0033] After adjustment, fully tighten the fixing bolts 11 on the vertical plate, and re-measure the height from the reducer base to the mounting shaft head of the coating roller coupling until it is completely suitable.

[0034] The following is a method for aligning the coaxiality between the coating roller of a coating machine and the output shaft of a speed reducer in conjunction with a specific embodiment.

[0035] like Figure 5 As shown, the coating roller shaft head 9 is installed on the coating roller bearing seat 15 through the coating roller bearing 16, the coating roller bearing seat 15 is connected to the frame vertical plate 14, the frame plate 13 is connected to the frame vertical plate 14, and the fixed base plate 12 is connected to the frame plate 13 through bolts. The reducer base 8 is fixed to the fixed base plate 12 with the provided fixing bolts 11 to ensure that the B surface of the reducer base vertical plate 1 and the A surface of the bottom plate 4 are perpendicular to each other; Figure 4 As shown, place the coating roller reducer 6 and the height gauge 5 on the bottom plate 4 of the reducer base, and measure the cylindrical line height h1 on the coating roller reducer shaft head 7. The value minus half of the diameter D1 of the coating roller reducer shaft head 7 is the center height of the reducer shaft head, that is, H1=h1-D1*1 / 2.

[0036] Adjust the movable measuring head 17 of the height gauge to the following value H1+D2*1 / 2=h2, such as Figure 5 , 6 As shown, this value is exactly equal to the center height H1 of the reducer shaft head, and D2 is the diameter of the coating roller shaft head; the reducer is retreated a certain space to put in the height gauge, and the mobile measuring head 17 is placed on the highest point of the cylindrical surface of the coating roller shaft head 9 for measurement. If H1≠H2, the reducer base 8 needs to be adjusted.

[0037] If the lower end face of the movable measuring head 17 is higher than the cylindrical surface on the shaft head of the coating roller, it means that the reducer base is high and needs to be adjusted downward: remove the reducer from the reducer base 8, loosen the fixing bolts 11 slightly, rotate (loosen) the two adjustment bolts 10 counterclockwise, the amplitude is basically equal to the height difference between the lower end face of the measuring head and the cylindrical surface on the shaft head of the coating roller, then tighten the fixing bolts 11, measure again, so that the bottom of the movable measuring head 17 is almost touching the cylindrical surface on the shaft head of the coating roller.

[0038] If the lower end face of the movable measuring head 17 is lower than the cylindrical surface on the shaft head of the coating roller, it means that the base of the reducer is low and needs to be adjusted upward: remove the reducer from the base 8, loosen the fixing bolts 11 slightly, and rotate the two adjusting bolts 10 clockwise with an amplitude basically equal to the height difference between the lower end face of the measuring head and the cylindrical surface on the shaft head of the coating roller, then tighten the fixing bolts 11, and measure again, so that the bottom of the movable measuring head 17 is almost touching the cylindrical surface on the shaft head of the coating roller.

[0039] When the height is adjusted properly, the inner hole of the coupling will be aligned with the shaft head of the coating roller more smoothly. Use a tool to gently tap the appropriate position of the coupling and push the reducer at the same time. The coupling will be smoothly in place. Tighten the top screw, fix the reducer fastening bolts, and test run. It is normal if there is no noise and no vibration.
