Description

Technical Field

[0001] This specification relates to the technical field of solar photovoltaics, and particularly to a conveying and deviation-correcting device for photovoltaic glass plates and a photovoltaic glass plate conveying device. Background Art

[0002] Photovoltaic glass plates are important encapsulation materials for solar components. Photovoltaic glass plates have the characteristics of high strength, high light transmittance, and high weather resistance. The tempered photovoltaic glass plates covering the photovoltaic modules can enable the photovoltaic modules to withstand greater wind pressure, sand and dust, hail, and large day-night temperature differences and harsh environments, protecting the solar cells. At the same time, after coating, the photovoltaic glass plates have the characteristic of high light transmittance, which can meet the need for the solar cells to generate more electric energy.

[0003] During the production process of photovoltaic glass plates, the raw materials become a glass plate belt after a series of technological processes. The glass plate belt is then cut and broken into sheet glass plates. During the subsequent production, packaging, and deep processing of the glass plates, they all need to be transported through conveying devices such as conveyor belts to reach each work station.

[0004] Due to the relatively long conveying distance of the glass plates and certain deviations in the outer diameter dimensions of the conveyor belt rollers and rollers, the glass plates will deviate during the conveying process and gradually move towards both sides of the conveyor belt.

[0005] In some current patents, deviation-correcting wheels are provided on both sides of the conveyor belt for deviation correction. For example, Chinese Patent CN217229436U discloses a conveying device for glass processing, including: a frame and a conveying mechanism, and further including a deviation-correcting mechanism. The deviation-correcting mechanism includes a mounting frame and a deviation-correcting part. The deviation-correcting part is adjustably arranged on the mounting frame and is used to abut against one side of the glass plate for deviation correction. Among them, the deviation-correcting part includes a deviation-correcting wheel, a mounting rod, and a fastening nut. During the process of the conveyor belt conveying the glass plate, one side of the glass plate abuts against the deviation-correcting wheel. When the glass plate deviates, the glass plate can be pushed towards the direction of the deviation-correcting wheel for deviation correction. However, during deviation correction, the corners of the glass plate collide severely with the deviation-correcting wheel, easily causing defects such as broken corners or broken pieces of the glass plate, and this will also result in a low service life of the deviation-correcting wheel, requiring frequent replacement of the retaining wheel and a relatively high maintenance cost. Summary of the Utility Model

[0006] One or more embodiments of this specification provide a conveying and deviation-correcting device for photovoltaic glass plates and a photovoltaic glass conveying device to solve the following technical problems: Due to certain deviations in the outer diameter dimensions of the conveyor belt rollers and rollers, the glass plates will deviate during the conveying process. In traditional deviation correction using deviation-correcting wheels, there are problems such as severe collision between the corners of the glass plate and the deviation-correcting wheel, easily causing defects such as broken corners or broken pieces of the glass plate, and a low service life of the deviation-correcting wheel.

In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope that conforms to the principles and features disclosed in the present application.

[0035] The rectifying device involved in the present application is a mechanical device for correcting the side error that occurs during the forward movement of the coil.

[0036] Embodiment 1

[0037] Refer to Figures 1 to 5, the present utility model provides a photovoltaic glass plate conveying and deviation correcting device 100, which includes a roller frame 1, a plurality of rollers 3 and a belt 4. The roller frame 1 is arranged on both sides of the conveyor belt 200 of the glass plate 300, and the length direction of the roller frame 1 extends from both sides of the conveyor belt 200 towards the center direction of the conveyor belt 200; the rollers 3 are sequentially installed in the roller frame 1 along the length direction of the roller frame 1 through roller shafts 2; the belt 4 is sleeved on the rollers 3 in the roller frame 1 and is used to push the glass plate 300 from both sides of the conveyor belt 200 towards the center direction of the conveyor belt 200.

[0038] In the present utility model, the deviation correcting device 100 is arranged on both sides of the conveyor belt 200, and the deviated glass plate 300 during transportation can be pushed from both sides of the conveyor belt 200 towards the center direction of the conveyor belt 200. Specifically, when the deviated glass plate 300 passes through the deviation correcting device 100, the front corner of the glass plate 300 will first contact the belt 4. As the glass plate 300 continues to move forward, the corner of the glass plate 300 will push the belt 4, causing the belt 4 and the rollers 3 to rotate together. At the same time, the belt 4 will give the glass plate 300 a thrust towards the center direction of the conveyor belt 200, causing the glass plate 300 to gradually move back to the center direction of the conveyor belt 200. When the glass plate 300 passes through the last roller 3 in the roller frame 1, the deviation correction of the glass plate 300 is completed. Since the belt 4 is used to contact the glass plate 300 in this application, there will be no impact on the corners of the glass plate 300. On the one hand, it can protect the glass plate 300, and on the other hand, it can also extend the service life of the deviation correcting device.

[0039] In some embodiments, the belt 4 can be made of wear-resistant elastic polyurethane material to prevent the impact on the corners of the glass plate from causing the glass plate to break.

[0040] Among them, the number and setting interval of the rollers 3 can be determined according to the length of the roller frame 1 and the diameter of the rollers 3, so as to support the belt 4, ensure that there is sufficient thrust when the belt 4 corrects the deviation, and will not be dented and deformed due to the collision of the glass plate 300.

[0041] Those skilled in the art can set the height of the roller frame 1 according to factors such as the structure of the conveyor belt and the height of the glass plate, so that the belt 4 cooperates with the corners of the glass plate 300. No specific limitation is made here.

[0042] Reference Figure 1 , in some embodiments, it further includes a mounting seat 12. The mounting seat 12 is fixed on both sides of the conveyor belt 200, and the side of the roller frame 1 facing away from the conveyor belt 200 is connected to the mounting seat 12 through a connecting rod assembly. The mounting seat 12 can be detachably fixed on both sides of the conveyor belt 200 through a bolt structure. Thus, the setting position and quantity of the deviation correcting device 100 can be adjusted flexibly, and it is also convenient for subsequent maintenance and update.

[0043] Reference Figure 5, the roller rack 1 can be set as a square tube shape with one side open, and the open side faces the direction of the conveyor belt 200 to expose the belt 4 for contacting the deviated glass plate 300, and the other side is a closed side for connecting the mounting seat 12.

[0044] Reference Figure 1 , in some embodiments, the connecting rod assembly includes a first connecting rod 7 and a second connecting rod 8 arranged in parallel. The first connecting rod 7 and the second connecting rod 8 are respectively pivotally connected to the roller rack 1 so that the angle between the length direction of the roller rack 1 and the advancing direction of the conveyor belt 200 is adjustable. Rotate the first connecting rod 7 and the second connecting rod 8 to adjust the angle between the roller rack 1 and the belt 4 and the advancing direction of the conveyor belt 200, ensuring that the glass plate 300 is pushed by the belt 4 to a suitable intermediate position in the conveyor belt 200, and then continue to be conveyed on the conveyor belt 200. It can be understood that the angle between the roller rack 1 and the advancing direction of the conveyor belt 200 can be set according to the angle of the glass plate 300 deviating from the advancing direction, and the two are complementary angles.

[0045] Reference Figure 1 , in some embodiments, the connecting rod assembly further includes a rotating shaft 9, an adjusting bolt 10 and a lock nut 11. One end of the first connecting rod 7 is pivotally connected to the roller rack 1 through the rotating shaft 9, and the other end of the first connecting rod 7 is fixed to the mounting seat 12. One end of the second connecting rod 8 is pivotally connected to the roller rack 1 through the rotating shaft 9, and the other end of the second connecting rod 8 is connected to the mounting seat 12 through the adjusting bolt 10 and the lock nut 11. Adjust the adjusting bolts 10 and lock nuts 11 on the two-sided deviation correction devices 100 to adjust the distance between the second connecting rod 8 and the mounting seat 12, thereby adjusting the angle between the roller rack 1 and the belt 4 and the advancing direction of the conveyor belt 200.

[0046] For the convenience of description, the part of the adjusting bolt 10 on the side of the mounting seat 12 close to the conveyor belt 200 can be called the connecting part, and the part of the adjusting bolt 10 on the side of the mounting seat 12 far from the conveyor belt 200 can be called the locking part. If the angle of the glass plate 300 deviating from the advancing direction decreases, it is necessary to increase the angle between the roller rack 1 and the advancing direction of the conveyor belt 200, shorten the connecting part of the adjusting bolt 10, drive the end of the roller rack 1 close to the side of the conveyor belt 200 to rotate away from the conveyor belt 200, and at the same time, the end close to the center of the conveyor belt 200 rotates towards the center of the conveyor belt 200.

[0047] In some embodiments, a displacement sensor may be provided to detect the position of the glass plate 300 to determine the deviation of the glass plate 300. Since it is difficult to measure the offset of the center position, the edge position of the glass plate can be taken as a reference and compared with the given value. If the glass plate is offset, a deviation correction device is used to correct the offset until it is within the requirements of the given value. Those skilled in the art can calculate based on the offset detected by the sensor to determine the angle between the roller frame 1 and the advancing direction of the conveyor belt 200.

[0048] In some embodiments, the end of the adjusting bolt 10 may also be connected to a motor, and both the motor and the displacement sensor are connected to a computer, and the angle between each deviation correction device 100 and the advancing direction of the conveyor belt 200 is automatically controlled through an automatic control algorithm.

[0049] Those skilled in the art can select a suitable sensor according to specific application scenarios, accuracy requirements, response speed, deviation correction requirements, etc. For example, an optoelectronic sensor can be selected for scenarios with high accuracy requirements.

[0050] Reference Figure 2 , in some embodiments, it further includes a bearing 5. The bearing 5 is sleeved on the roller shaft 2, and the roller 3 is installed on the roller shaft 2 through the bearing 5. The bearing 5 can support the rotation of the roller 3, reduce the friction coefficient during its movement, and ensure its rotational accuracy.

[0051] Reference Figure 2 , in some embodiments, it further includes a bearing retainer 6. The bearing retainer 6 is sleeved on the roller shaft 2 and presses against both sides of the bearing 5. The bearing retainer 6 can prevent the bearing 5 from moving up and down during rotation, thereby ensuring the smooth rotation of the roller 3.

[0052] Reference Figure 2 , in some embodiments, the two end faces of the roller 3 are provided with flanges for preventing the belt 4 from falling off. The flanges can prevent the belt 4 from deviating and falling off. Among them, the flanges can extend outward from the end face, showing a circular ring shape connected to the end face of the roller 3, so as to prevent the belt 4 from moving along the axial direction of the roller 3 during rotation and falling off the roller 3. In order to reduce the manufacturing cost, simplify the manufacturing process, and improve the connection stability, the roller 3 and the flanges can be manufactured by an integral molding method.

[0053] Reference Figure 2, in some embodiments, the roller rack 1 is provided with a plurality of mounting holes 111 penetrating through the top surface and the bottom surface for mounting the roller shaft 2. It can be understood that the mounting holes 111 correspond in position and are equal in number on the top surface and the bottom surface of the roller rack 1, so that the roller shaft 2 can pass through the mounting holes 111 on the top surface and the bottom surface of the roller rack 1 and penetrate through the roller rack 1. The number and the interval of the mounting holes 111 can be determined according to the length of the roller rack 1 and the diameter of the roller 3, so that the roller 3 can provide sufficient support for the belt 4.

[0054] Reference Figure 2 , in some embodiments, the roller shaft 2 includes a flange portion, a shaft portion and a fastening portion. The shaft portion is a smooth cylinder for cooperating with the bearing 5. The flange portion and the fastening portion are respectively located at both ends of the shaft portion. The flange portion is a flange with a diameter larger than the mounting hole 111. The fastening portion is provided with threads for cooperating with a nut to fix the roller shaft 2 on the roller rack 1.

[0055] Reference Figure 1 , in some embodiments, the mounting holes 111 at the ends of the roller rack 1 are provided with a plurality of hole positions arranged along the length direction of the roller rack 1. By adjusting the matching position of the roller shaft 2 and the hole positions of the mounting holes 111, the mounting position of the roller 3 at the end of the roller rack 1 is adjusted according to the roller shaft 2, so that the tension of the belt 4 can be adjusted.

[0056] Since belt transmission depends on the friction between the belt 4 and the roller 3, adjusting the tension of the belt 4 can ensure the best friction effect. If the belt 4 is too loose, it will cause the belt 4 to run unstably or the roller 3 to slip. If the belt 4 is too tight, it will cause excessive stretching and shorten the service life of the belt 4.

[0057] It can be understood that the mounting holes 111 can be provided at both ends of the roller rack 1, or only at one end of the roller rack 1.

[0058] In some embodiments, the mounting hole 111 at the end of the roller frame 1 can be any one of an elongated shape, a connecting round hole, and a special-shaped hole. Among them, the mounting hole 111 at the end of the roller frame 1 can be in the shape of an elongated strip, and the length direction of the elongated strip is consistent with the length direction of the roller frame. By adjusting the fitting position of the roller shaft 2 and the mounting hole 111, the mounting position of the roller 3 at the end of the roller frame 1 can be adjusted according to the roller shaft 2, so as to adjust the tension of the belt 4. To facilitate the fitting of the roller shaft 2 and the mounting hole 111, multiple intersecting circular holes can also be connected as a whole to form a connecting round hole. A connecting round hole includes multiple circular holes, and each circular hole can cooperate with the roller shaft 2. The fitting position of the roller shaft 2 and the mounting hole 111 can be adjusted according to the requirement of the belt tension. In some other cases, the middle cross-section of the roller shaft 2 is circular to facilitate cooperation with the bearing 5, and the end can be set to have a square, diamond or other special-shaped cross-section for cooperation with the square, diamond or other special-shaped mounting hole 111. After the non-circular mounting hole 111 is fitted, it is more firm and not easy to deviate and fall off.

[0059] In summary, the utility model can achieve the following beneficial effects:

[0060] (1) The deviation rectifying devices 100 are arranged on both sides of the conveyor belt 200, and the glass plate 300 that deviates during the conveying process can be pushed towards the center direction of the conveyor belt 200.

[0061] (2) Since the belt 4 is used to contact the glass plate 300 in this application, there will be no impact on the corners of the glass plate 300, and the glass plate 300 can be protected. Specifically, when the deviating glass plate 300 passes through the deviation rectifying device 100, the front corner of the glass plate 300 will first contact the belt 4. As the glass plate 300 continues to move forward, the corners of the glass plate 300 will push the belt 4, causing the belt 4 and the roller 3 to rotate together. At the same time, the belt 4 will give the glass plate 300 a thrust towards the center direction of the conveyor belt 200, causing the glass plate 300 to gradually move back to the center of the conveyor belt 200. When the glass plate 300 passes through the last roller 3 in the roller frame 1, the deviation rectification of the glass plate 300 is completed.

[0062] (3) By adjusting the adjusting bolts 10 and lock nuts 11 on the deviation rectifying devices 100 on both sides, the distance between the second connecting rod 8 and the mounting seat 12 is adjusted, so as to adjust the included angle between the roller frame 1 and the belt 4 and the advancing direction of the conveyor belt 200, and ensure that the glass plate 300 is conveyed at a suitable middle position on the conveyor belt 200.

[0063] (4) The roller frame 1 is provided with a plurality of mounting holes 111 penetrating the top surface and the bottom surface for mounting the roller shaft 2. The mounting holes 111 at the end of the roller frame 1 are provided with multiple hole positions. By adjusting the fitting position of the roller shaft 2 and the mounting hole 111, the position of the roller 3 at the end of the roller frame 1 can be adjusted, and further the tension of the belt 4 can be adjusted.

[0068] Among them, it can be understood that the number of photovoltaic glass plate conveying deviation rectifying devices provided can be determined according to the length of the conveyor belt 200, and the setting interval of the photovoltaic glass plate deviation rectifying device can be determined according to the length of the glass plate 300 and the deviation situation of the conveyor belt 200 at this position. If the glass plate 300 runs off to one side of the conveyor belt 200 and does not run off to the other side, the deviation rectifying device 100 can also be provided only on one side of the conveyor belt 200.
