Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic module production, in particular to a sand belt state detection component for a corner rubbing machine in photovoltaic module production. Background Technique

[0002] The frame of a photovoltaic module is cut to the required length during the production process, but the cut is sharp after cutting. If the frame manufacturer polishes the cut before leaving the factory, it will make the corner joints of the assembled frame prone to occur. To avoid this problem, it is usually chosen to use a corner rubbing machine to polish and rub the four corners of the frame after the frame assembly is completed. The corner rubbing machine polishes through a set of rotating sand belts. The sand belts are sleeved outside the driving wheel and the driven wheel. The driving wheel is driven by a driving motor and is responsible for providing the rotating power for the sand belts.

[0003] During the long-term use of the existing corner rubbing machine, the sand belts are prone to wear and breakage. Since the corner rubbing machine cannot self-check the state of the sand belts, it makes the staff unable to detect the breakage of the sand belts in time, resulting in the four corners of the frame of the photovoltaic module being missed during polishing after the sand belts break. Secondly, after the corner rubbing machine runs for a long time, the fixed shafts inside the driving wheel and the driven wheel will also be worn to a certain extent. This wear will cause the fixed shafts to shake with the mounting table, so that the fixed shafts, the driving wheel and the driven wheel all rotate eccentrically. When the rotation of the driving wheel and the driven wheel is no longer balanced, the fixation of the sand belts will also be affected. The position of the sand belts may shift, resulting in uneven or incomplete polishing. When the staff carry and install the photovoltaic module, its unpolished frame is extremely easy to scratch the skin. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a sand belt state detection component for a corner rubbing machine in photovoltaic module production. The technical solution of the utility model is as follows:

[0005] A sand belt state detection component for a corner rubbing machine used in photovoltaic module production, including two photoelectric sensors II respectively installed directly above two fixed shafts and one photoelectric sensor I installed behind the sand belt. Both of the two fixed shafts are rotationally connected to the installation table through bearings. Through holes are provided on the top surfaces of the two fixed shafts. The light beams of the two photoelectric sensors II are irradiated inside the corresponding through holes, and the light beam of the photoelectric sensor I is irradiated on the sand belt. An upper end of the outer side of one of the fixed shafts is fixedly connected with a driving wheel, and an upper end of the outer side of the other fixed shaft is fixedly connected with a driven wheel. The sand belt is sleeved on the outer sides of the driving wheel and the driven wheel. A lower end of the fixed shaft inside the driving wheel penetrates through the installation table and is connected with a driving component for driving the driving wheel to rotate. A hexagonal column is fixedly connected to the upper surface of the installation table and behind the sand belt. Three hexagonal moving blocks are slidably connected to the outer side of the hexagonal column. The three hexagonal moving blocks are relatively fixed to the hexagonal column through fixing members. Connecting plates are fixedly connected to the front sides of the three hexagonal moving blocks. A front side of the upper surface of the lower connecting plate is rotationally connected with an L-shaped plate for fixing the photoelectric sensor I, and a front side of the upper surface of the two upper connecting plates are rotationally connected with long plates for fixing the photoelectric sensors II.

[0006] Optionally, a bottom plate is fixedly connected to the lower end of the hexagonal column, and the bottom plate is fixedly connected to the upper surface of the installation table through bolts.

[0007] Optionally, grooves are provided on both the left and right sides of the hexagonal column. The fixing member is a locking bolt. Threaded holes are provided through both the left and right sides of the hexagonal moving block. The locking bolt is threadedly penetrated through the threaded hole and abuts against the surface of the groove.

[0008] Optionally, a first threaded column is fixedly connected to the front side of the upper surface of the lower connecting plate.

The L-shaped plate is movably sleeved on the outer side of the first threaded column through the first rotation hole. A first nut is threadedly sleeved on the outer side of the first threaded column and above the horizontal short side of the L-shaped plate.

[0009] Optionally, a first U-shaped notch for installing the photoelectric sensor I is provided on the vertical long side of the L-shaped plate.

[0010] Optionally, second threaded columns are fixedly connected to the front sides of the upper surfaces of the two upper connecting plates.

The long plate is movably sleeved on the outer side of the second threaded column through the second rotation hole. A second nut is threadedly sleeved on the outer side of the second threaded column and above the long plate.

[0011] Optionally, a second U-shaped notch for installing the photoelectric sensor II is provided on the surface of the long plate.

[0012] All of the above optional technical solutions can be arbitrarily combined, and the present utility model does not elaborate on the structures after combination one by one.

[0013] With the above solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. The present utility model opens a through hole on the top surface of the fixed shaft and installs a second photoelectric sensor directly above the through hole. The second photoelectric sensor can detect the operating state of the fixed shaft in real time. By installing a first photoelectric sensor behind the abrasive belt to detect the operating state of the abrasive belt in real time, it can effectively solve the problems that may occur during the long-term use of the existing corner rubbing machine, such as the abrasive belt breaking and the abrasive belt shifting due to the wear of the fixed shaft, making the grinding effect more uniform and thorough, and avoiding the situation where the skin of the staff is scratched when handling and installing photovoltaic modules.

Specific embodiments

[0025] The following will further describe in detail the specific embodiments of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0026] Please refer to Figure 1-7 , the present utility model provides a detecting assembly for the state of the abrasive belt of a corner rubbing machine for photovoltaic module production, including two groups of second photoelectric sensors 10 respectively installed directly above two groups of fixed shafts 1 and one group of first photoelectric sensors 8 installed behind the abrasive belt 14. The two groups of fixed shafts 1 are both rotatably connected to the mounting table 3 through bearings. Through holes 11 are provided on the top surfaces of the two groups of fixed shafts 1. The light beams of the two groups of second photoelectric sensors 10 are both irradiated inside the corresponding through holes 11. The light beam of the first photoelectric sensor 8 is irradiated on the abrasive belt 14. An upper end outside one group of fixed shafts 1 is fixedly connected with a driving wheel 12, and an upper end outside the other group of fixed shafts 1 is fixedly connected with a driven wheel 13. The abrasive belt 14 is sleeved outside the driving wheel 12 and the driven wheel 13. The lower end of the fixed shaft 1 inside the driving wheel 12 penetrates through the mounting table 3 and is connected with a driving assembly 2 for driving the driving wheel 12 to rotate. A hexagonal column 4 is fixedly connected to the upper surface of the mounting table 3 and behind the abrasive belt 14. Three hexagonal moving blocks 5 are slidably connected to the outside of the hexagonal column 4. The three hexagonal moving blocks 5 are all relatively fixed to the hexagonal column 4 through fixing members. Connecting plates 6 are fixedly connected to the front sides of the three hexagonal moving blocks 5. An L-shaped plate 7 for fixing the first photoelectric sensor 8 is rotatably connected to the front side of the upper surface of the lower group of connecting plates 6. Long plates 9 for fixing the second photoelectric sensors 10 are rotatably connected to the front sides of the upper surfaces of the two upper groups of connecting plates 6.

[0027] The utility model detects the state of the abrasive belt 14 in real time through a group of photoelectric sensors I 8 and two groups of photoelectric sensors II 10, so as to solve the problems that the abrasive belt 14 may break and the abrasive belt 14 may shift due to the wear of the fixed shaft 1 during the long-term use of the existing chamfering machine. Specifically, a through hole 11 is opened on the top surface of the fixed shaft 1, and a photoelectric sensor II 10 is installed directly above the through hole 11, and the light beam of the photoelectric sensor II 10 irradiates inside the through hole 11. Under normal conditions, the light beam of the photoelectric sensor II 10 is in an unobstructed state. When the fixed shaft 1 is worn, it will cause the fixed shaft 1 to rotate eccentrically, thereby blocking the light beam of the photoelectric sensor II 10. The photoelectric sensor II 10 transmits a signal to the machine platform, and the machine platform gives an automatic alarm. A photoelectric sensor I 8 is installed behind the abrasive belt 14, and it is ensured that the light beam of the photoelectric sensor I 8 irradiates on the abrasive belt 14. Under normal conditions, the light beam of the photoelectric sensor I 8 is in an obstructed state. When the abrasive belt 14 is worn and broken, the light beam of the photoelectric sensor I 8 is no longer blocked. At this time, the photoelectric sensor I 8 will transmit a signal to the machine platform, and the machine platform gives an automatic alarm. Through the automatic alarm of the machine platform, the staff can timely know that the abrasive belt 14 is broken or the fixed shaft 1 is worn, and thus take measures in time, effectively reducing the occurrence of the situation where the frame is not polished.

[0028] It should be noted that the photoelectric sensor I 8 and the photoelectric sensor II 10 can transmit signals to the machine platform, and the machine platform gives an automatic alarm. The circuit structures and technical details involved in this process are all conventional means in the prior art, and will not be elaborated in this article.

[0029] Specifically, by adjusting the relative position of the hexagonal moving block 5 outside the hexagonal column 4, the height adjustment of the photoelectric sensor I 8 and the photoelectric sensor II 10 is realized to ensure that the photoelectric sensor I 8 and the photoelectric sensor II 10 can correctly align with the abrasive belt 14 or the through hole 11. After the adjustment is completed, a fixing member is used to fix the relative positions of the hexagonal moving block 5 and the hexagonal column 4. Both the hexagonal column 4 and the hexagonal moving block 5 adopt a hexagonal shape, which can prevent the hexagonal moving block 5 and the hexagonal column 4 from rotating relative to each other.

[0030] Specifically, during the installation of the photoelectric sensor I 8, according to the position of the abrasive belt 14, the orientation of the photoelectric sensor I 8 can be indirectly adjusted by rotating the L-shaped plate 7 to make it better align with the abrasive belt 14. During the installation of the photoelectric sensor II 10, according to the position of the fixed shaft 1, the position of the photoelectric sensor II 10 can be indirectly adjusted by rotating the long plate 9.

[0031] Furthermore, the lower end of the hexagonal column 4 is fixedly connected with a bottom plate 41, and the bottom plate 41 is fixedly connected to the upper surface of the installation table 3 through bolts.

[0032] Specifically, the hexagonal column 4 is fixed on the upper surface of the mounting table 3 through the bottom plate 41. As a connecting piece, the bottom plate 41 can firmly fix the hexagonal column 4 on the surface of the mounting table 3.

[0033] Furthermore, grooves 42 are provided on both the left and right sides of the hexagonal column 4. The fixing member is a locking bolt 51. Threaded holes 52 are provided through both the left and right sides of the hexagonal moving block 5. The locking bolt 51 is threaded through the threaded hole 52 and abuts against the surface of the groove 42.

[0034] Specifically, after the relative position of the hexagonal moving block 5 and the hexagonal column 4 is adjusted, the locking bolt 51 is tightened so that the end of the locking bolt 51 abuts against the surface of the groove 42, thereby ensuring that the relative position between the hexagonal moving block 5 and the hexagonal column 4 does not change.

[0035] Furthermore, a first threaded column 61 is fixedly connected to the front side of the upper surface of the lower set of connecting plates 6. A first rotating hole 72 is provided through the surface of the short horizontal side of the L-shaped plate 7. The L-shaped plate 7 is movably sleeved outside the first threaded column 61 through the first rotating hole 72. A first nut 62 is threadedly sleeved on the outside of the first threaded column 61 and above the short horizontal side of the L-shaped plate 7.

[0036] Specifically, when adjusting the orientation of the first photoelectric sensor 8, the first nut 62 needs to be loosened first. At this time, the L-shaped plate 7 can rotate relative to the connecting plate 6. After the adjustment is completed, the first nut 62 is tightened and abuts against the upper surface of the short horizontal side of the L-shaped plate 7. At this time, the relative position of the L-shaped plate 7 and the connecting plate 6 is fixed, thereby ensuring that the position of the first photoelectric sensor 8 is stable during the detection process.

[0037] Furthermore, a first U-shaped notch 71 for installing the first photoelectric sensor 8 is provided on the long vertical side of the L-shaped plate 7.

[0038] Specifically, the first U-shaped notch 71 provides an installation position for the first photoelectric sensor 8.

[0039] Furthermore, second threaded columns 63 are fixedly connected to the front sides of the upper surfaces of the two upper sets of connecting plates 6. A second rotating hole 92 is provided through the surface of the side of the long plate 9 close to the connecting plate 6. The long plate 9 is movably sleeved outside the second threaded columns 63 through the second rotating hole 92. Second nuts 64 are threadedly sleeved on the outside of the second threaded columns 63 and above the long plate 9.

[0040] Specifically, when adjusting the position of the second photoelectric sensor 10, the second nut 64 needs to be loosened first. At this time, the long plate 9 can rotate relative to the connecting plate 6. Then, adjust the orientation of the long plate 9 according to the position of the fixed shaft 1. After the adjustment is completed, tighten the second nut 64 and make it abut against the upper surface of the long plate 9. At this time, the relative position of the long plate 9 and the connecting plate 6 is fixed, so as to ensure that the position of the first photoelectric sensor 8 is in a stable state during the detection process.

[0041] Furthermore, a U-shaped notch two 91 for installing the second photoelectric sensor 10 is provided on the surface of the long plate 9.

[0042] Specifically, the U-shaped notch two 91 provides an installation position for the second photoelectric sensor 10. When installing the second photoelectric sensor 10, after the orientation of the long plate 9 is adjusted, the relative position of the second photoelectric sensor 10 and the long plate 9 can be adjusted according to the position of the through hole 11 at this time, so that it is more accurately aligned with the through hole 11.

[0043] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
