[0004] In the prior art, when measuring glue weight, operators need to stop the photovoltaic module production line, place a cup under the glue dispenser's outlet, and press the dispenser's quantitative glue button three times. When the glue in the cup meets the process requirements, the photovoltaic module production line is restarted to continue production. This entire operation is quite cumbersome and affects the normal production rhythm of the production line. Utility Model Content

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The auxiliary tooling for detecting the glue output of the glue filling machine provided by the exemplary embodiment of the present utility model can be conveniently installed on the junction box of the photovoltaic module through the positioning structure, so that the glue connection groove of the auxiliary tooling is located above the junction box, so that the glue filling process of the glue filling machine can be the same as the normal glue filling process of the photovoltaic module, without the need to stop the machine. After the glue filling is completed, the auxiliary tooling can be removed to carry out weighing detection of the potting glue.

[0035] Figure 1 This is a schematic diagram of the three-dimensional exploded structure of the glue dispensing machine glue output detection auxiliary tooling according to the embodiment of the present utility model; Figure 3 This is a schematic diagram of the axonometric structure of the auxiliary tooling for detecting the glue output of the glue filling machine according to the present invention. Figure 1 and Figure 3 The figure shows the top and bottom structures of the panel 10 from top and bottom views, respectively. The auxiliary tooling of the exemplary embodiment of the present invention has at least one glue groove 11 formed on the top surface of the panel 10. The number of glue grooves 11 depends on the number of actual junction boxes of the photovoltaic module. For example, if the number of junction boxes of the photovoltaic module is three, the number of glue grooves 11 along the length of the panel 10 is also three to receive the potting glue from the glue outlet of the glue potting machine.

[0036] For example, the bottom surface of the panel 10 has at least one positioning structure, which can be opposite to the top surface glue groove 11. The number of positioning structures can be three, that is, the positioning structures correspond one to one with the junction boxes, or two, and the two positioning structures are installed corresponding to two of the three junction boxes respectively, which can also stably fix the panel 10 to the photovoltaic module.

[0037] In actual application, the plate body 10 is installed on the junction box of the photovoltaic module on the normal production line through the positioning structure. When the photovoltaic module is conveyed to the bottom of the glue filling machine, since the glue connection groove 11 of the plate body 10 is located above the corresponding junction box, the glue filling machine discharges glue normally according to actual production. After the glue is discharged from the glue outlet of the glue filling machine, the potting glue is injected into the corresponding glue connection groove 11 of the plate body 10. Then the operator controls the conveying direction of the conveyor line and transfers the photovoltaic module installed with auxiliary tooling to the quality defective station (Non-Go, NG). Then, the operator removes the plate body 10 from the junction box of the photovoltaic module and weighs the potting glue in the glue connection groove 11. As a result, the glue filling machine on the normal production line does not stop and does not affect the normal production rhythm of the photovoltaic module. At the same time, the measured glue weight is the real glue amount in the actual production environment, which is more accurate than the simulated glue amount in the prior art.

[0038] Figure 2 yes Figure 1 A partial enlarged view of part A. Figure 1 and Figure 2 As shown, a guide portion 111 is further formed on the side wall of the glue connecting groove 11 . Along the direction from the bottom surface to the top surface, the guide portion 111 gradually extends away from the glue connecting groove 11 .

[0039] A flow guide 111 is formed on one or both sidewalls of the glue groove 11. This flow guide 111 facilitates pouring out the potting adhesive in the glue groove 11 for weighing. For example, the flow guide 111 can be a portion of the sidewall that protrudes outward from the main body of the sidewall, forming a pointed beak or other shape that provides a diversion function. In the height direction of the board 10, specifically, the flow guide 111 gradually moves away from the glue groove 11 from the bottom to the top of the board 10, and the height of the flow guide 111 is consistent with the height of the glue groove 11.

[0040] Exemplarily, each guide portion 111 is located on the same side of the plate body 10 to facilitate pouring out the potting glue in each glue groove 11 at the same time.

[0041] Figure 5 2 is a schematic diagram of the isometric structure of the glue splicing box 20 according to the embodiment of the present utility model; Figure 6 This is a side view of the glue box according to the embodiment of the present invention. Figure 2 、 Figure 5 and Figure 6 As shown, the auxiliary tooling of the exemplary embodiment of the present invention further includes at least one glue splicing box 20, which is detachably arranged in the glue splicing groove 11. For example, the number of the glue splicing boxes 20 is the same as the number of the glue splicing grooves 11.

[0042] In actual applications, the auxiliary tooling is normally installed on the junction box of the photovoltaic module. After the glue is injected by the glue filling machine, the potting glue is contained in the corresponding glue box 20. After the photovoltaic module is transferred to the NG station, the auxiliary tooling is removed, and each glue box 20 is taken out from the glue filling groove 11, and the potting glue in each glue box 20 is weighed separately. It should be noted that in the actual process of potting glue of the junction box, since the volume of the middle junction box is smaller than that of the junction boxes on both sides, the glue output of the glue filling machine corresponding to the middle junction box is smaller than the glue output corresponding to the junction boxes on both sides. The existing technology is to stop the machine and manually press the quantitative glue output button of the glue filling machine three times, and weigh the total weight of the three glue outputs. This only simulates the potting of three junction boxes, not the actual potting glue injected into a single junction box. Based on this, by weighing the potting glue of each glue box 20 separately, the real glue weight of a single junction box can be measured.

[0043] Continue as Figure 5 and Figure 6 As shown, the glue splicing box 20 includes a box body 21 and at least one holding portion 22 provided on the box body 21. The holding portion 22 is located at the top of the side wall of the box body 21 and extends toward the outside of the box body 21. The box body 21 matches the glue splicing groove 11, and the holding portion 22 is located on the top surface of the plate body 10.

[0044] The box body 21 can have an interference fit with the glue splicing groove 11, that is, the box body 21 is snap-fitted into the glue splicing groove 11, thereby stably fixing the glue splicing box 20 to the plate body 10. The box body 21 can also have a transition fit with the glue splicing box 20, and the handle 22 extending from the outer periphery of the box body 21 can easily remove the box body 21 from the glue splicing groove 11. When the box body 21 is installed in the glue splicing groove 11, the handle 22 does not embed into the glue splicing groove 11, but is exposed above the top surface of the plate body 10, or is attached to the top surface of the plate body 10 (the circumference of the glue splicing groove 11 on the top surface).

[0045] For example, the number of grips 22 on the box body 21 can be one, two, or four. When there are two grips 22, the two grips 22 are located on two opposite side walls of the box body 21, so that the glue box 20 can be smoothly removed from the glue splicing tank 11 without spilling. When there are four grips 22, the four grips 22 are located on the four side walls of the box body 21.

[0046] Figure 3 This is a schematic diagram of the axonometric structure of the auxiliary tooling for detecting the glue output of the glue filling machine according to the utility model; Figure 4 yes Figure 3 Considering the convenience of the board 10 being detachably mounted on the junction box of the photovoltaic module, as shown in FIG. Figure 3 and Figure 4As shown, the positioning structure includes four positioning plates 12 provided on the bottom surface of the plate body 10 . The four positioning plates 12 surround a positioning groove, and the positioning groove is adapted to the junction box on the photovoltaic module.

[0047] For example, four positioning plates 12 are vertically arranged on the bottom surface of the panel body 10. The four positioning plates 12 enclose a shape that matches the outer contour of the junction box. Adjacent two positioning plates 12 may be spaced apart or connected to each other. The heights of the four positioning plates 12 may be consistent or inconsistent. For example, when one side of the junction box has electrical connection wires, the height of the positioning plate 12 corresponding to that side may be lower than the height of the remaining three positioning plates 12 to avoid the aforementioned electrical connection wires. The heights of the remaining three positioning plates 12 may be the same as the height of the junction box to ensure that the panel body 10 is positioned as accurately and stably as possible and installed on the photovoltaic module.

[0048] For example, the positioning grooves defined by the four positioning plates 12 can have either an interference fit or a transition fit with the junction box. When the positioning grooves defined by the four positioning plates 12 have an interference fit with the junction box, the plate 10 is highly stable on the photovoltaic module. When the positioning grooves have a transition fit with the junction box, the plate 10 is easily installed or removed from the junction box of the photovoltaic module.

[0049] In an optional embodiment, the positioning structure includes a positioning groove formed on the bottom surface of the plate body 10, which is adapted to the junction box. The positioning groove formed on the bottom surface of the plate body 10 is consistent with the shape, size and actual application of the positioning groove formed by the four positioning plates 12 above, and will not be repeated here.

[0050] For example, Figure 3 As shown, the number of positioning grooves can be consistent with the number of junction boxes of the photovoltaic module, for example, three; the number of positioning grooves can also be two, for example, the two positioning grooves correspond to the junction boxes on both sides of the photovoltaic module respectively, and no positioning groove is set on the bottom surface of the board 10 at the position corresponding to the junction box located in the middle of the photovoltaic module. The board 10 can also be accurately fixed on the photovoltaic module, so that the glue groove 11 on the top surface of the board 10 can be positioned below the glue outlet of the glue filling machine.

[0051] An exemplary embodiment of the present utility model also provides a photovoltaic module production system, including a conveyor line and the auxiliary tooling in the above embodiment, wherein the auxiliary tooling is fixed to the junction box of the photovoltaic module through a positioning structure; the conveyor line is used to convey the photovoltaic module after the auxiliary tooling is glued to the weighing station.

[0052] Exemplarily, the photovoltaic module production system further includes a control device, which is communicatively connected to the conveyor line.

[0053] In practice, at the pre-cleaning station of the photovoltaic module production system, operators install auxiliary tooling onto photovoltaic modules in normal production. After the auxiliary tooling is filled with glue by the glue dispenser, the operator manually controls the conveyor line to transfer the photovoltaic module to the NG station or weighing station by pressing the NG button on the production system. At these stations, operators weigh the potting glue in the glue box 20. If the glue quantity meets the process weight requirement, the photovoltaic module production system can continue production; otherwise, the glue dispenser output needs to be adjusted.

[0054] The technical advantages of the above photovoltaic module production system over the existing technology are consistent with the technical advantages of the glue filling machine glue output detection auxiliary tooling of the above embodiment, and will not be repeated here.

[0055] Those skilled in the art will appreciate that the above embodiments are merely intended to clearly illustrate the present invention and are not intended to limit the scope of the present invention. Other variations or modifications may be made based on the above disclosure, and such variations or modifications are still within the scope of the present invention.
