[0002] During the production of photovoltaic modules, the cells are connected into a battery string through a marking and welding machine. After the battery string is stacked with the front panel and the back panel, it goes through lamination, framing and other processes. After the framing process, the junction box is installed, glued and welded to achieve the sealing of the junction box. AB glue is generally used for glue pouring, and glue A and glue B need to be poured in a certain proportion. At present, AB glue is transported by pipeline and poured through a nozzle connected to the pipeline. If the glue contains foreign matter and blocks the pipeline during the pouring of AB glue, it is necessary to manually clean the pipeline. Manual cleaning is difficult and time-consuming, which seriously affects the operation of the equipment and causes waste of production capacity. If the foreign matter is small and does not completely block the pipeline, the proportion of glue A and glue B will be incorrect, resulting in the phenomenon that the glue cannot be cured. When the glue cannot be cured, defective components will be produced. Defective components need to be repaired, and rework will cause waste of resources and manpower and reduce production efficiency.

[0030] The embodiment of the present application provides a filtering device 10 to solve at least one of the following problems in the conventional technology of photovoltaic module production process when installing the junction box and pouring glue, when the AB glue is transported by pipeline: when the glue contains foreign matter, it is easy to block the discharge pipeline; it is difficult and time-consuming to manually clean the blocked pipeline, which affects the operation of the equipment and causes waste of production capacity; when the foreign matter blocked in the pipeline causes the incorrect pouring ratio of A glue and B glue, resulting in the inability to solidify the glue, the defective components need to be repaired, resulting in waste of resources and manpower and reduced production efficiency. The filtering device 10 will be described below in conjunction with the accompanying drawings.

[0031] The filter device 10 provided in the embodiment of the present application is exemplary, see Figure 1 As shown, Figure 1 The structure diagram of the filtering device 10 provided in the embodiment of the present application is shown in FIG. The filtering device 10 of the present application can be used for AB glue filtering, glue discharging, and glue filling, and can be specifically used in the junction box installation and glue filling process of photovoltaic module production.

[0032] In order to more clearly illustrate the structure of the filter device 10, the filter device 10 will be described below in conjunction with the accompanying drawings. Figure 1As shown, a filter device 10 includes a filter component 100 and a mounting component 200. The filter component 100 has a filter cavity and at least one filter hole 101 connected to the filter cavity. The maximum size of the filter hole 101 is not more than 4 mm. The mounting component 200 is connected to the filter component 100. The mounting component 200 has a discharge channel 201 that communicates with the filter cavity. The mounting component 200 can be arranged in the accommodating cavity of the rubber container and connected to the inner wall of the rubber container or the discharge pipe on the rubber container to achieve the discharge channel 201 communicating with the discharge pipe. It should be noted that the maximum size of the above-mentioned filter hole 101 can refer to parameters such as length and inner diameter. For example, when the filter hole 101 is a regular shape such as a circle, an ellipse, a triangle, or a square, the maximum size of the filter hole 101 is the length, the inner diameter, etc. When the filter hole 101 is an irregular shape, the maximum size of the filter hole 101 is the distance between the two farthest points in the shape.

[0033] The above-mentioned filter device 10 filters the foreign matter contained in the glue in the glue container by setting the filter component 100 and the filter hole 101 on the filter component 100, so as to achieve the purpose of not clogging the discharge pipe. The maximum size of the filter hole 101 is not more than 4mm, so it can filter most of the granular foreign matter. The filtered foreign matter is mainly concentrated on the outer wall of the filter component 100 and the glue container. Since the inner diameter of the discharge pipe is small and it is not convenient to disassemble, and the size of the glue container is large, it is only necessary to clean the outer wall of the filter component 100 and the glue container during cleaning, and there is no need to clean the discharge pipe, so the cleaning is faster and more convenient. When the filter device 10 is used to accommodate the filtration of A glue or B glue, since the discharge pipe is basically not blocked, the glue output ratio of A glue and B glue is correct, avoiding the phenomenon that the glue cannot be cured due to the incorrect glue output ratio of A glue and B glue, ensuring the curing of the glue, reducing or avoiding the defective rate of photovoltaic modules, reducing or avoiding the return rate, and saving resources and labor costs.

[0034] In some embodiments, the filter holes 101 may be one or more of square holes, circular holes, elliptical holes, triangular holes, and other polygonal holes. Preferably, the plurality of filter holes 101 may be of the same shape, which is convenient for processing.

[0035] In some embodiments, the filter hole 101 is a circular hole. The aperture of the filter hole 101 is 1 mm to 4 mm. The aperture of the filter hole 101 should not be too large or too small. When the aperture of the filter hole 101 is too large, it cannot effectively filter foreign matter of larger size, and cannot solve the problem of foreign matter contained in the glue blocking the discharge pipe in the traditional technology; when the aperture of the filter hole 101 is too small, it will cause a slow glue discharge speed, low efficiency of the glue injection equipment, and reduce the production efficiency of the component. Therefore, when the aperture of the filter hole 101 is preferably 1 mm to 4 mm, it can effectively filter most of the impurities in the glue while ensuring that the glue passes smoothly, ensuring that the glue injection equipment will not cause malfunctions due to foreign matter blocking the discharge pipe during operation, and can greatly guarantee the normal operation of the glue injection equipment.

[0036] In some of the embodiments, it should be noted that the sizes of the filter holes 101 may be the same or different.

[0037] In some embodiments, there are multiple filter holes 101. Multiple filter holes 101 are spaced apart on the surface of the filter component 100. Multiple filter holes 101 can increase the filtering speed of the glue and ensure that the glue passes smoothly into the discharge pipe. The number of filter holes 101 can be set according to the overall size of the filter component 100 as needed.

[0038] In some embodiments, the filter component 100 is a columnar structure. The side of the filter component 100 has a filter hole 101. Preferably, the side of the filter component 100 has a plurality of filter holes 101, and the plurality of filter holes 101 are distributed at intervals. The mounting component 200 is connected to one of the end faces of the filter component 100. Preferably, the side of the filter component 100 has a plurality of filter holes 101 evenly distributed.

[0039] In some of the embodiments, at least one end surface of the filter component 100 may also be provided with one or more of the above-mentioned filter holes 101 .

[0040] In some embodiments, the filter component 100 is a cylindrical structure. A plurality of filter holes 101 are spaced apart on the side surface, i.e., the outer peripheral wall, of the filter component 100. Preferably, the plurality of filter holes 101 are distributed in an array. The distribution rule of the filter holes 101 can be a multi-row and multi-column distribution, which is not specifically limited in the present application.

[0041] In some embodiments, when the filter component 100 is cylindrical, the outer diameter of the filter component 100 is 10 mm to 100 mm. The outer diameter of the filter component 100 can be set according to the size of the plastic container used in conjunction.

[0042] In some embodiments, when the filter component 100 is in a columnar structure, the length of the filter component 100 along its axial direction is 10 mm to 500 mm. The outer diameter of the filter component 100 and the length of the filter component 100 are based on the capacity of the filter component 100 to be contained in the filter cavity. The size of the filter component 100 should not be too large. When the size of the filter component 100 is too large, the material cost of the filter component 100 is high. In addition, the size of the filter component 100 should not be too small. When the size of the filter component 100 is too small, the number of filter holes 101 distributed on the filter component 100 is small, which affects the passing speed of the glue and reduces the discharge speed of the glue.

[0043] In some embodiments, the side of the filter component 100 is provided with a filter hole 101, and one of the end faces of the filter component 100 is not provided with a filter hole 101, and the end face is used to connect the mounting component 200. The side of the filter component 100 close to the mounting component 200 forms a blank area 102. Another part of the side of the filter component 100 forms a filter area 103, and the filter area 103 has a plurality of filter holes 101. It is not difficult to understand that in this embodiment, the filter hole 101 may be provided on the other end face of the filter component 100 where the mounting component 200 is not provided, or the filter hole 101 may not be provided, and the specific setting can be based on actual needs.

[0044] In some of these embodiments, see Figure 1 As shown, along the axial direction of the filter component 100, the ratio of the length L1 of the blank area 102 to the length L2 of the filter area 103 is 1:(4~9). For example, the ratio of the length L1 of the blank area 102 to the length L2 of the filter area 103 is 1:4, that is, the length L1 of the blank area 102 accounts for 1 / 5 of the total side length (L1+L2) of the filter component 100. When the filter device 10 is installed on the top of the glue container, the mounting component 200 is located at the top and the filter component 100 is located at the bottom. There is no glue at the top of the glue container. Therefore, the blank area 102 of the filter component 100 does not need to be provided with a filter hole 101, reducing the processing cost. When the filter device 10 is installed at the bottom of the glue container, the mounting component 200 is located at the bottom and the filter component 100 is located at the top, when the glue in the glue container is used up, the filtered foreign matter is concentrated at the bottom of the glue container. At this time, the blank area 102 can block the foreign matter and prevent some foreign matter from entering the filter cavity and the discharge pipe.

[0045] An embodiment of the present application also provides a glue injection device.

[0046] A glue injection device includes a glue container, a discharge pipe and the above-mentioned filtering device 10. The glue container and the discharge pipe are not shown in the accompanying drawings. The glue container has a receiving cavity for receiving glue, and the glue container can receive glue A or glue B. The number of glue containers can be multiple. When the glue injection device is used for AB glue injection, one of the glue containers is used to receive glue A, and the other glue container is used to receive glue B, and a filtering device 10 is respectively provided in each glue container. The discharge pipe is located outside the glue container and connected to the glue container. One end of the discharge pipe is connected to the nozzle, and the other end of the discharge pipe is communicated with the receiving cavity. The filtering device 10 is arranged in the receiving cavity and is detachably connected to the inner wall of the glue container or the discharge pipe through the mounting component 200. The discharge channel 201 of the mounting component 200 is communicated with the discharge pipe. When the mounting component 200 is connected to the discharge pipe, one end of the discharge pipe extends into the accommodating cavity of the rubber container and the outer wall of the discharge pipe is sealed and connected to the rubber container.

[0047] In the present application, since the mounting component 200 is detachably connected to the rubber container or the discharge pipe, the filter device 10 can be directly removed during cleaning, and the filter device 10 and the rubber container or the discharge pipe can be easily and quickly removed. During cleaning, the rubber container and the filter device 10 can be directly cleaned without cleaning the discharge pipe. This makes it more convenient and quick for operators to perform maintenance and care, greatly saving labor costs and time costs, and also improving component yield.

[0048] In some of the embodiments, the glue container may be a glue barrel.

[0049] In some embodiments, the mounting member 200 has an external thread. The inner wall of the rubber container or the discharge pipe has an internal thread. The mounting member 200 is connected to the inner wall of the rubber container or the discharge pipe through a thread. The threaded connection between the mounting member 200 and the inner wall of the rubber container can realize the rapid disassembly and installation of the filter device 10 and the rubber container, saving time and effort.

[0050] It is not difficult to understand that in other examples, the mounting component 200 and the rubber container or the discharge pipe may be connected in a snap-on, magnetic, or other manner.

[0051] In summary, after the filter device 10 of the present application is used in the glue injection equipment, it can filter the glue in the glue container. Foreign matter larger than the size of the filter hole 101 will not enter the discharge pipe. The filtered foreign matter is concentrated in the glue container or adheres to the outer wall of the filter component 100. The operator can directly clean the glue container and the filter component 100 without cleaning the discharge pipe, which greatly reduces the difficulty of manual cleaning, reduces the cleaning time, and improves the operation efficiency of the glue injection equipment and the production capacity of the components. When the glue injection equipment is used to accommodate glue A or glue B, the discharge pipe will not be blocked, so the glue discharge ratio of glue A and glue B is correct, which does not affect the curing of glue A and glue B, reduces defective products, reduces or avoids rework, improves the quality of component products, and reduces the production cost of components.

[0052] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
