[0001] The present application relates to the technical field of photovoltaic module production, and in particular to a photovoltaic module edge sealing mechanism and edge sealing equipment. Background Art

[0002] Photovoltaic modules can generally be divided into single-glass photovoltaic modules and double-glass photovoltaic modules according to the number of glass plates in their composition structure.

[0007] A glue-applying component, used to apply the tape to the edge of the photovoltaic module;

[0008] The tape feeding assembly includes a feed roller and a take-up roller, wherein the feed roller is used to install the tape and the take-up roller is used to take up the release paper of the tape;

[0009] The guide assembly includes a separation guide wheel and a first guide wheel; in the guide assembly, the separation guide wheel is arranged close to the tape feeding assembly, and the first guide wheel is arranged close to the gluing assembly; the separation guide wheel is used to wind the tape released by the discharge roller and guide the tape separated from the release paper to the first guide wheel, and the first guide wheel is used to guide the tape separated from the release paper to the gluing assembly.

[0010] In some embodiments, the tape supply assembly further comprises:

[0011] The covering and pressing member is detachably arranged at the end of the unwinding roller and / or the winding roller, and is used for covering and pressing the end surface of the tape roll and / or the release paper roll.

[0012] In some embodiments, the cover press comprises:

[0013] A mounting plate, used for mounting the cover pressing member on the end of the unwinding roller and / or the winding roller;

[0014] A mounting shaft, fixedly arranged on one side of the mounting plate;

[0015] a pressing plate slidably disposed on the mounting shaft along the central axis of the mounting shaft;

[0016] An elastic member is sleeved on the mounting shaft, one end of the elastic member is connected to the pressing plate, and the other end is connected to the mounting plate.

[0017] In some embodiments, the cover pressing member further comprises:

[0018] The adjusting block is threadably matched with the mounting shaft and is located on a side of the pressing plate away from the mounting plate.

[0019] In some embodiments, the pressure plate has a protrusion and an edge extension, the protrusion forms a receiving groove, the elastic member and the mounting plate are located in the receiving groove, and the edge extension is distributed along the circumference of the receiving groove at the opening of the receiving groove.

[0020] In some embodiments, the guide assembly further comprises:

[0021] The second guide wheel is arranged between the separation guide wheel and the winding roller, and is used for guiding the adhesive tape separated from the release paper to the winding roller.

[0022] In some embodiments, the separation guide wheel and the first guide wheel both include a limiting roller, wherein the limiting roller has a winding portion and a limiting portion located at one end of the winding portion, wherein the limiting portion is used to prevent the adhesive tape from moving in a direction along the central axis of the limiting roller;

[0023] When the guide assembly further includes a second guide wheel, the second guide wheel also includes the limiting roller.

[0024] In some embodiments, the guide assembly further comprises:

[0025] An adjusting gasket is provided at one end of the winding portion away from the limiting portion, and is used to extend the dimension of the winding portion along the central axis direction of the limiting roller.

[0026] In some embodiments, the guide assembly further comprises:

[0027] A plurality of leveling wheels are distributed between the first guide wheel and the separation guide wheel.

[0028] The present application also provides a photovoltaic module edge sealing device, the photovoltaic module edge sealing device comprising:

[0029] Any edge banding mechanism as described above.

[0030] The beneficial effects of the embodiments of the present application are as follows: the photovoltaic module edge sealing mechanism provided by the present application includes a gluing assembly, a tape feeding assembly, and a guide assembly. Specifically, by providing a take-up roller in the tape feeding assembly and a separation guide wheel in the guide assembly, when a tape with release paper is provided on the discharge roller, the tape is discharged from the discharge roller and passes around the separation guide wheel, where the release paper and the tape are separated at the separation guide wheel. The tape separated from the release paper is stretched to the first guide wheel, and the end of the release paper is wound around the take-up roller. As the take-up roller rotates, the release paper is collected.

[0031] When the ends of the unwinding roller and / or the winding roller are detachably provided with a covering and pressing piece, the adhesive tape roll and the release paper roll can be prevented from spreading out.

[0032] When the separation guide wheel and the first guide wheel both include a limiting roller, since the limiting roller has a winding part and a limiting part, when the tape is wound on the winding part of the limiting roller, the limiting part is located at the upper edge of the tape. Since the lower edge of the tape is limited by the mounting surface of the limiting roller, this can prevent the tape from moving up and down during the edge sealing process, thereby ensuring the edge sealing effect.

[0033] In addition, by setting an adjusting gasket at one end of the winding part away from the limiting part, the length of the winding part can be extended, so that the length of the winding part can be adjusted by adjusting the number of gaskets set, so that the photovoltaic module edge sealing mechanism can be suitable for tapes of different widths, further expanding the scope of application of the photovoltaic module edge sealing mechanism for tapes.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0047] See also Figures 1 to 3 The present application provides a photovoltaic module edge sealing mechanism 100, including a gluing assembly 30, a tape feeding assembly 10 and a guide assembly 20. The gluing assembly 30 is used to apply the tape to the edge of the photovoltaic module. The tape feeding assembly 10 includes a discharge roller 11 and a winding roller 12. The discharge roller 11 is used to install the tape, and the winding roller 12 is used to wind up the release paper of the tape. The guide assembly 20 includes a separation guide wheel 23 and a first guide wheel 21. In the guide assembly 20, the separation guide wheel 23 is arranged near the tape feeding, and the first guide wheel 21 is arranged near the gluing assembly 30. The separation guide wheel 23 is used to wind the tape discharged by the discharge roller 11, and guide the tape separated from the release paper to the first guide wheel 21. The first guide wheel 21 is used to guide the tape separated from the release paper to the gluing assembly 30.

[0048] When using a tape with release paper, the tape is placed on the unloading roller 11, and the unloaded tape passes around the separation guide wheel 23. The release paper and the tape are separated at the separation guide wheel 23. The tape separated from the release paper is stretched to the first guide wheel 21, and the end of the separated release paper is wound around the winding roller 12. As the unloading roller 11 rotates to unload the tape, the winding roller 12 is driven to rotate to wind the separated release paper around the winding roller 12, thereby realizing the use of the tape with release paper.

[0049] The tape feed assembly 10 includes a feed roller 11 for loading the tape, and a take-up roller 12 for taking up the release paper. Both the feed roller 11 and the take-up roller 12 can be cylindrical rollers. The tape is rolled up and secured to the feed roller 11 in the form of a tape roll. The feed roller 11 is driven to rotate, thereby rotating the tape roll and unwinding the tape from the roll. The end of the release paper separated at the separation guide wheel 23 is secured to the take-up roller 12, which is then driven to rotate to wind the release paper into a release paper roll.

[0050] like Figure 1 and Figure 2 As shown, in some embodiments, the tape feeding assembly 10 may further include a cover pressing member 13. The cover pressing member 13 is detachably provided at the end of the unwinding roller 11 and / or the winding roller 12, and is used to cover the end surface of the tape adhesive and / or the release paper roll. Taking the placement state of the photovoltaic module edge sealing mechanism 100 during normal use as an example for explanation, it can be understood that the bottom of the unwinding roller 11 and the winding roller 12 are both provided with a supporting plate for carrying the tape roll and the release paper roll respectively, and the cover pressing member 13 is detachably provided at the end of the unwinding roller 11 and / or the winding roller 12, that is, the cover pressing member 13 is detachably provided at the upper end of the unwinding roller 11 and / or the winding roller 12. The cover pressure member 13 can be a circular plate-like structure. For example, when the tape roll is placed on the unwinding roller 11, the lower end of the tape roll contacts the support. By providing the cover pressure member 13 on the upper end of the unwinding roller 11, the cover pressure member 13 can press the upper end of the tape roll, thereby preventing the tape roll from unraveling. Similarly, the upper end of the take-up roller 12 can also be removably provided with the cover pressure member 13 to prevent the release paper roll from unraveling. In the embodiment of the present application, the upper ends of both the unwinding roller 11 and the take-up roller 12 are provided with the cover pressure member 13 as an example. Furthermore, by detachably coupling the cover pressure member 13 to the upper ends of the unwinding roller 11 and the take-up roller 12, the tape roll and the release paper roll can be easily removed and placed. In the embodiment of the present application, the specific method of detachably coupling the cover pressure member 13 to the upper ends of the unwinding roller 11 and the take-up roller 12 is not limited; for example, it can be a snap-fit, a threaded fit, or a threaded fastener connection.

[0051] To prevent the cover pressing member 13 from compressing the tape roll and preventing it from unraveling while also preventing the tape from being unwound, in some embodiments, the cover pressing member 13 can be configured to elastically contact the tape roll. For example, the cover pressing member 13 can include a mounting plate 131, a mounting shaft 132, a pressure plate 133, and an elastic member 134. The mounting plate 131 is used to mount the cover pressing member 13 on the end of the unwinding roller 11 and / or the take-up roller 12. For example, the mounting plate 131 can be fixedly mounted to the end of the unwinding roller 11 and / or the take-up roller 12 using threaded fasteners. Taking the unwinding roller 11 as an example, the mounting shaft 132 is fixedly disposed on the side of the mounting plate 131 away from the unwinding roller 11, and the pressure plate 133 is slidably disposed on the mounting shaft 132 along the central axis of the mounting shaft 132. The elastic member 134 is sleeved on the mounting shaft 132, with one end of the elastic member 134 connected to the pressure plate 133 and the other end connected to the mounting plate 131. Thereby, after the adhesive tape roll is placed on the unwinding roller 11, after the cover pressing member 13 is set, the pressing plate 133 in the cover pressing member 13 can elastically contact with the end face of the adhesive tape roll. Wherein, the elastic member 134 can be a rubber sleeve or a spring, but is not limited thereto.

[0052] Please also refer to Figure 4 In some embodiments, the cover pressure member 13 may further include an adjustment block 135. After the pressure plate 133 is slidably disposed on the mounting shaft 132, the upper end of the mounting shaft 132 passes through the pressure plate 133. The adjustment block 135 is located on the side of the pressure plate 133 away from the mounting plate 131 and is threadedly engaged with the mounting shaft 132. The highest position of the pressure plate 133 on the mounting shaft 132 can be adjusted by rotating the adjustment block 135. On the one hand, the degree of pressure of the pressure plate 133 on the tape roll can be adjusted, and on the other hand, the winding roller 12 can be adapted to tapes of different widths. In addition, by removing the adjustment block 135 from the mounting shaft 132, the pressure plate 133 can be removed from the mounting shaft 132, so that the tape roll can be taken in and out by disassembling the pressure plate 133.

[0053] like Figure 4 As shown, in some embodiments, the pressure plate 133 may have a raised portion 133a and an edge extension 133b. The raised portion 133a forms a receiving groove 133c, in which the elastic member 134 and the mounting plate 131 are located. The edge extensions 133b are distributed along the circumference of the receiving groove 133c at the opening of the receiving groove 133c. In this way, when the pressure plate 133 is brought into contact with the end surface of the tape roll, the edge extension 133b of the pressure plate 133 is brought into contact with the end surface of the tape roll, thereby preventing the mounting plate 131 from interfering with the contact between the pressure plate 133 and the end surface of the tape roll. The cross-sectional shape of the receiving groove 133c corresponds to the shape of the mounting plate 131, for example, both are circular, but are not limited to this.

[0054] The guide assembly 20 is used to guide the tape discharged from the tape feeding assembly 10 to the gluing assembly 30. When the tape discharged from the discharge roller 11 in the tape feeding assembly 10 contains release paper, the guide assembly 20 is also used to guide the release paper separated from the tape to the take-up roller 12 for rewinding. The separation guide wheel 23 and the first guide wheel 21 in the guide assembly 20 can both be cylindrical rollers.

[0055] Please also refer to Figure 5 and Figure 6 In some embodiments, the separation guide wheel 23 and the first guide wheel 21 may both include a limiting roller 25. The limiting roller 25 has a winding portion 251 and a limiting portion 252 located at one end of the winding portion 251. For example, the limiting roller 25 may be a roller structure with a shoulder structure, but is not limited thereto. When in use, the adhesive tape is wound around the circumference of the winding portion 251, and the limiting portion 252 is used to prevent the adhesive tape from moving along the central axis of the limiting roller 25. This ensures the linearity of the adhesive tape during the edge sealing process, thereby improving the edge sealing effect of the photovoltaic module. It should be noted that both the separation guide wheel 23 and the first guide wheel 21 are rotatable. The photovoltaic module edge-sealing mechanism 100 or the photovoltaic module edge-sealing equipment generally includes mounting surfaces for the separation guide wheel 23 and the first guide wheel 21. The separation guide wheel 23 will be used as an example. During use, the limiting portion 252 of the separation guide wheel 23 is located at the upper end, allowing the mounting surfaces of the limiting portion 252 and the first guide wheel 21 to vertically limit the position of the adhesive tape. To adapt the guide assembly 20 to adhesive tapes of varying widths, the guide assembly 20 may further include an adjustment shim 26. During use, the adjustment shim 26 is disposed at the end of the winding portion 251 distal from the limiting portion 252 and serves to extend the dimension of the winding portion 251 along the central axis of the limiting roller 25. It will be appreciated that the radial dimension of the adjustment shim 26 corresponds to the radial dimension of the winding portion 251. This means that by disposing different numbers of adjustment shims 26 at the lower end of the limiting roller 25, the length of the winding portion 251 can be adjusted to accommodate adhesive tapes of varying widths. In the embodiment of the present application, there is no limitation on the specific thickness of the adjusting gasket 26 , and the thickness can be set according to the width specification of the adhesive tape used.

[0056] like Figure 2 and Figure 3As shown, in some embodiments, the guide assembly 20 may further include a second guide wheel 22. The second guide wheel 22 is disposed between the separation guide wheel 23 and the winding roller 12, and is used to guide the release paper to the winding roller 12. It is understood that when in use, the tape stretched out from the unloading roller 11 passes between the separation guide wheel 23 and the second guide wheel 22, wherein the release paper bypasses the second guide wheel 22 and extends to the winding roller 12, and the tape separated from the release paper bypasses the separation guide wheel 23 and extends to the first guide wheel 21. By providing the second guide wheel 22, when the winding roller 12 winds up the release paper, the tension of the winding roller 12 on the release paper can be prevented from affecting the adhesion of the tape released from the unloading roller 11 to the circumferential surface of the separation guide roller, thereby ensuring the stability of the tape feeding. It should be noted that when the guide assembly 20 includes the second guide wheel 22, the second guide wheel 22 may also include a limiting roller 25.

[0057] like Figure 1 and Figure 3 As shown, in some embodiments, the guide assembly 20 may further include a plurality of smoothing wheels 24. The smoothing wheels 24 are distributed between the first guide wheel 21 and the separation guide wheel 23. For example, the smoothing wheels 24 may be cylindrical rollers. When in use, the tape is tightened so that it adheres closely to the circumference of the smoothing wheels 24, preventing the tape from twisting and causing the adhesive surfaces of the tape to adhere to each other.

[0058] It should be noted that the photovoltaic module edge sealing mechanism 100 provided in the above embodiment of the present application is as follows: Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 The arrow in the figure indicates the direction of extension of the tape in the photovoltaic module edge sealing mechanism 100. Along the direction of extension of the tape, the tape scissor assembly 40, the edge sealing assembly 50, and the smoothing assembly 60 are further provided after the gluing assembly 30. After the gluing assembly applies the tape to the edge of the photovoltaic module, the tape scissor assembly 40 cuts the tape, the edge sealing assembly 50 bends the upper and lower edges of the tape toward the upper and lower surfaces of the photovoltaic module, respectively. The smoothing assembly 60 then applies the upper and lower edges of the tape to the upper and lower surfaces of the photovoltaic module, respectively. It is understood that each operating component in the photovoltaic module is connected to a corresponding drive source. Depending on the operating characteristics of each operating component, the drive source can be a drive cylinder or a drive motor, but is not limited thereto. The winding roller 12 and the unwinding roller 11 can use the same drive source, and are connected by a synchronous belt. The speed ratio between the synchronous pulleys of the winding roller 12 and the synchronous pulleys of the unwinding roller 11 is designed based on the different tape roll diameters.

[0059] In other embodiments, the present application further provides a photovoltaic module edge sealing device, comprising the photovoltaic module edge sealing mechanism 100 in any of the above embodiments.

[0060] The photovoltaic module edge sealing equipment provided in this application adopts all the technical solutions of all the embodiments of the above-mentioned photovoltaic module edge sealing mechanism 100, and therefore has at least all the beneficial effects brought about by the technical solutions of the embodiments of the above-mentioned photovoltaic module edge sealing mechanism 100, which will not be repeated here one by one.

[0061] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
