[0002] Photovoltaic frames are auxiliary materials used in photovoltaic modules, located in the mid-to-downstream of the photovoltaic industry chain. The performance of photovoltaic frames directly affects the installation and lifespan of photovoltaic modules. Aluminum frames have long been the mainstream photovoltaic frames due to their lightweight, ease of processing, aesthetics, and good weather resistance. However, in recent years, rising aluminum prices have limited room for price reductions, and aluminum frames account for a significant portion of module manufacturing costs, approaching 10%. Driven by the photovoltaic industry's demand for cost reduction, new frame types are entering a phase of rapid industrialization. Among them, composite material frames have outstanding advantages in cost, performance, and environmental protection, and are expected to usher in a period of rapid industrialization.

[0003] Pultrusion molding is a process for producing high-performance polymer-based composite materials in the form of continuous long products with a constant cross-section. In the pultrusion molding process, the pre-forming and curing of the mold are as follows: the reinforcing material from the yarn frame and glue tank is pre-formed and initially shaped, then enters the mold for curing, and finally the cured reinforcing glass yarn is cut into fixed-length products by a cutting tool.

[0004] During the production process, the pultrusion molding process requires the simultaneous pulling of dozens or even hundreds of glass yarns. The glass yarns are all pulled internally, so the remaining amount of glass yarn in the bobbin cannot be seen from the surface. It is impossible for workers to detect in time that the glass yarn on the bobbin has been used up, which may lead to insufficient glass yarn in the composite material and affect the performance of the composite material.

[0026] As Figs. 1 to 3 As shown in the application, a glass yarn pay-off rack for pultrusion production line is disclosed, including rack body 1, rack body 1 includes a plurality of layers of stacked placement table 11, each placement table 11 is provided with a plurality of placement areas for placing glass yarn drum, each placement area includes bottom plate 21, weighing device 22 and weighing plate 23, weighing device 22 is located between bottom plate 21 and weighing plate 23, and weighing plate 23 is used for carrying glass yarn drum.

[0027] The application measures the weight of each glass yarn drum individually by arranging weighing device 22 in the placement area, ensures that the staff can be reminded to replace the glass yarn drum in time when the glass yarn drum is about to be consumed, and guarantees the smooth production.

[0028] In the present application, the glass yarn barrel is extracted by the inner pulling yarn method, the yarn head is drawn out from the inside of the glass yarn barrel, and the inside of the glass yarn barrel is gradually extracted during the extraction process, and the outside does not change, so it is difficult for the staff to judge the remaining amount of the glass yarn barrel by direct observation. Because the specific gravity of glass yarn is 2.2-2.66g / cm³, which is twice that of yarn, the weight of the glass yarn barrel will change more obviously during the extraction of the glass yarn, so the extraction process can be monitored by the weighing device 22, and the condition of the glass yarn barrel is fed back to the staff; and when the weight of the spool measured by the weighing device 22 does not change, the spool has not been extracted glass yarn, at this time the glass yarn may be broken or the weighing device 22 is malfunctioning, which can remind the staff to handle the abnormality as soon as possible to maintain the normal production of pultrusion; and the weight difference between the full glass yarn spool and the exhausted glass yarn spool is relatively large, which can better set the alarm threshold of the weighing device 22 to ensure that the staff has enough reaction time.

[0029] The receiving table 11 is provided with an accommodating space for placing the bottom plate 21, the weighing device 22 and the weighing plate 23, and the top surface of the receiving table 11 is not lower than the top surface of the weighing plate 23 when the glass yarn barrel is not placed, so that the difficulty of placing the glass yarn barrel on the weighing plate 23 by the staff is reduced, and the glass yarn barrel can be directly pushed onto the weighing plate 23.

[0030] In the present application, two rows of storage areas are provided on the receiving table 11, so that the glass yarn barrels can be placed from the front and rear sides of the yarn placing frame, saving the occupied area and maximizing the utilization rate of the factory space.

[0031] All the weighing devices 22 are connected with the controller, and the weighing device will transmit the weight of the corresponding glass yarn barrel to the controller in real time, and the controller will compare the detected weight of the glass yarn barrel with the preset value, and when the detected weight of the glass yarn barrel is lower than the preset value, the controller will remind the staff to replace the glass yarn barrel.

[0032] The alarm structure is also provided in the storage area, which is used to alarm when the weighing device 22 detects that the weight of the glass yarn barrel in the storage area is lower than the preset value. The frame body 1 is also connected with a display 5.

[0033] During the pultrusion production, about 100 glass yarn barrels are pulled at the same time, and the remaining amount of each glass yarn barrel can be displayed on the display 5 in real time, and when the remaining amount of the glass yarn barrel is less than the preset value, the staff can be reminded to replace the glass yarn barrel.

[0034] In the present embodiment, the alarm structure includes a lighting assembly 31 provided on the frame body 1.

[0035] Through the lighting assembly 31, the staff can find the storage area of the glass yarn cylinder to be replaced more quickly after receiving the glass yarn cylinder replacement reminder of the controller, thereby improving the efficiency of finding the storage area of the glass yarn cylinder to be replaced.

[0036] The lighting assembly can be a three-color lamp, which displays different colors to represent the remaining amount state of the corresponding glass yarn cylinder.

[0037] Further, in another embodiment, the alarm structure includes a sound-emitting assembly arranged in the storage area.

[0038] The sound-emitting assembly can be a buzzer or a sound box. Through the sound-emitting assembly, the staff is better reminded that the glass yarn cylinder in the storage area needs to be replaced through sound, thereby ensuring better reminding effect.

[0039] A leveling assembly is arranged below the bottom plate 21, and the leveling assembly is used to adjust the bottom plate 21 to be horizontal.

[0040] The leveling assembly is used to adjust the bottom plate to be horizontal, so that the weighing device 22 is in a horizontal state during work, and the data obtained by the weighing device 22 is more accurate.

[0041] A yarn guide plate 4 is arranged above each layer of the storage table 11, and the yarn guide plate 4 is located above the storage area. The yarn guide plate 4 is provided with a plurality of yarn guide holes 41, and the yarn guide holes are used to pass through the glass yarn.

[0042] Since a plurality of storage areas are arranged on each storage table 11, in order to avoid that the plurality of glass yarn cylinders are entangled and knotted during the extraction process, the glass yarns drawn out of different glass yarn cylinders are staggered with each other, so that they do not interfere with each other during the extraction process, and a better working state is ensured.

[0043] If the storage table 11 can be provided with a plurality of yarn guide plates 4 on the storage table, the distance between the glass yarn cylinder and the yarn guide plate 4 is not too long, so that the glass yarn drawn out of other glass yarn cylinders is not entangled and knotted, and the normal extraction of the glass yarn is better ensured.

[0044] Further, in order to reduce the friction between the glass yarn and the yarn guide plate 4, a yarn guide paper can be arranged on the yarn guide hole 41, so that the extraction effect is better.

[0045] Further, in another embodiment, the two sides of the bottom surface of the weighing plate 23 are provided with side plates 231.

[0046] Since the weighing plate 23 will be lifted with the production process, it is easy to cause the space where the weighing device 22 is located to be communicated with the outside, so that the glass yarn or other substances enter, which may affect the normal use of the weighing device 22; and the side plate 231 is arranged, which can also ensure that the space where the weighing device 22 is located is not directly communicated with the outside during the lifting process, so that the glass yarn or other substances are not easy to enter the space, and the stable use of the weighing device 22 is better ensured.
