[0038] Figure 1 It is a schematic diagram of a tape edge-sealing device in a first perspective in an embodiment of the present application; Figure 2 It is a schematic diagram of a tape edge-sealing device in a second perspective in an embodiment of the present application; Figure 3 It is a schematic diagram when the tape edge-sealing device in an embodiment of the present application seals the edge of the plate body 010. As Figures 1 to 3 shown, the tape edge-sealing device provided by the embodiment of the present application is used to seal the edge of the plate body 010, that is, to wrap the edge of the plate body 010 with the tape 020 to achieve protection. The plate body 010 can be a laminate in a photovoltaic module or other plate bodies 010 that need edge-sealing for protection. The tape edge-sealing device includes a base 100 and a tape mounting member 500, a guide wheel set 200, and a pressing component 300 provided on the base 100. The tape mounting member 500 is used for mounting and releasing the tape 020, and the guide wheel set 200 is used to abut against the tape 020 passing through the guide wheel set 200 and guide the tape 020 to wrap the edge of the plate body 010. Along the movement path of the tape 020, the pressing component 300 is located downstream of the guide wheel set 200. The pressing component 300 includes a first pressing roller 320 and a second pressing roller 330 arranged at intervals. The first pressing roller 320 and the second pressing roller 330 are used to clamp the edge of the plate body 010 to press the tape 020. In this embodiment, by setting the pressing component 300, when the edge of the plate body 010 passes through the pressing component 300, the first pressing roller 320 and the second pressing roller 330 can clamp the edge of the plate body 010, so as to press the tape 020 that has been wrapped around the edge of the plate body 010, making the tape 020 more reliably adhered to the surface of the plate body 010. In addition, in the embodiment of the present application, the tape edge-sealing device further includes a release film recycling member 600 and a guiding component 400 provided on the base 100. The release film recycling member 600 is used for winding and recycling the release film 021 peeled off from the tape 020, and the guiding component 400 is used to guide the plate body 010 to move towards the guide wheel set 200.

[0039] It should be understood that during the edge sealing operation, the tape 020 will move relative to the tape edge sealing device. The movement path of the tape 020 refers to the movement path of the tape 020 relative to the tape edge sealing device with the tape edge sealing device as a reference. Similarly, during the edge sealing operation, the plate body 010 will also move relative to the tape edge sealing device. The movement path of the plate body 010 refers to the movement path of the plate body 010 relative to the tape edge sealing device with the tape edge sealing device as a reference. Of course, in actual use, either the plate body 010 can be fixed and the tape edge sealing device can move, or the tape edge sealing device can be fixed and the plate body 010 can move.

[0040] The base 100 is a component for carrying the tape mounting member 500, the release film recycling member 600, the guiding assembly 400, the guide wheel set 200, and the pressing assembly 300. In this embodiment, the base 100 is in a plate shape and has a certain strength; in other alternative embodiments, the base 100 can be of other shapes as long as it has the shape and strength to support and fix the relevant components of the tape edge sealing device.

[0041] Next, the components on the base 100 will be introduced in the order from upstream to downstream according to the movement path of the tape 020.

[0042] The tape mounting member 500 is rotatably mounted on the base 100. The tape 020 can be wound around the tape mounting member 500. The tape mounting member 500 can rotate actively or passively to realize the release of the tape 020. For example, under the pulling of the tape 020, the tape mounting member 500 will rotate to release the tape 020, or the tape mounting member 500 can be driven by a motor to rotate to realize the release of the tape 020 (or provide assistance to assist the release of the tape 020).

[0043] In this embodiment, a first traction wheel 120 and a second traction wheel 130 are further provided on the base 100. The tape 020 passes through the first traction wheel 120 and the second traction wheel 130 and is abutted against the outer peripheral surfaces of the first traction wheel 120 and the second traction wheel 130. The first traction wheel 120 and the second traction wheel 130 define a part of the movement path of the tape 020.

[0044] In this embodiment, the release film recovery member 600 is rotatably connected to the base 100 and is located near the second traction wheel 130. It should be understood that when the adhesive tape 020 is stored on the adhesive tape mounting member 500 in a wound form, its adhesive surface is covered by the release film 021. The function of the release film 021 is to protect the adhesive surface of the adhesive tape 020, keep the adhesive surface clean, and then ensure that the adhesive tape 020 has good adhesion during edge sealing. Before the adhesive tape 020 reaches the edge of the plate body 010, the release film 021 needs to be removed, and the removed release film 021 can be recovered by the release film recovery member 600 by winding. In this embodiment, the release film 021 is separated from the adhesive tape 020 at the second traction wheel 130, and the release film 021 is wound onto the release film recovery member 600. The release film recovery member 600 can be driven to rotate by a driving assembly to wind up the release film 021, or can be wound manually; or, the release film recovery member 600 can be connected to the first traction wheel 120, the second traction wheel 130 or the tape installation member 500 by transmission, so that it can rotate synchronously with the first traction wheel 120, the second traction wheel 130 or the tape installation member 500 during the edge sealing process, thereby realizing the winding and recovery of the tape 020. In this embodiment, the release film recovery member 600 is driven by the second traction wheel 130 through the transmission belt 610, so that during the edge sealing process, when the second traction wheel 130 is driven by the tape 020 to rotate, the release film recovery member 600 can also rotate synchronously, thereby realizing the winding and recovery of the release film 021.

[0045] In this embodiment, the guide wheel group 200 includes a plurality of guide wheels arranged in sequence along the movement path of the adhesive tape 020, and the guide wheels are rotatably connected to the base 100. At least part of the guide wheels have a guide groove 221 extending around the guide wheel circumference on the outer circumference side, and the guide groove 221 has two guide slopes 222 spaced apart in the axial direction of the guide wheel, and the two guide slopes 222 are arranged at an angle so that the bottom width of the guide groove 221 is smaller than the opening width, and the guide groove 221 is used to cooperate with the edge of the plate body 010, and when the guide wheel rolls relative to the plate body 010, the guide slope 222 is used to guide the adhesive tape 020 to wrap around the edge of the plate body 010.

[0046] When edge sealing is performed, the edge of the plate body 010 will extend into the guide groove 221 and move along the tangent direction of each guide wheel. In this process, the adhesive surface of the tape 020 contacts the edge of the plate body 010 and has a tendency to wrap the edge of the plate body 010, and the non-adhesive surface of the tape 020 abuts against the inner wall of the guide wheel, and the guide wheel rolls on the non-adhesive surface of the tape 020.

[0047] In this embodiment, the guide wheel set 200 includes a first guide wheel 210, a second guide wheel 220, and a third guide wheel 230. A limiting groove 211 is provided on the outer peripheral side of the first guide wheel 210. The limiting groove 211 is used to limit the axial position of the tape 020 relative to the first guide wheel 210. Guide grooves 221 are respectively provided on the second guide wheel 220 and the third guide wheel 230. In this embodiment, the axes of the respective guide wheels are parallel. The limiting groove 211 of the first guide wheel 210 can position the tape 020 to ensure that it has a proper position axially and can be aligned with the edge of the plate body 010. The guide grooves 221 of the second guide wheel 220 and the third guide wheel 230 have guide slopes 222, which can guide the two sides in the width direction of the tape 020 to bend towards the front and back surfaces of the plate body 010, so that it has a tendency to wrap around the edge of the plate body 010.

[0048] In this embodiment, the width of the limiting groove 211 on the first guide wheel 210 can be set to be slightly larger than the width of the tape 020, while the bottom width of the guide grooves 221 on the second guide wheel 220 and the third guide wheel 230 should be smaller than the width of the tape 020, so that the guide slopes 222 can press against both sides of the tape 020, causing the two sides of the tape 020 to bend towards the front and back surfaces of the plate body 010, thus having a tendency to wrap around the edge of the plate body 010. Optionally, the width of the bottom of the guide groove 221 can be equivalent to the thickness of the plate body 010.

[0049] Furthermore, the guide wheel set 200 further includes a pressing wheel 240. Along the movement path of the tape 020, the pressing wheel 240 is located downstream of the multiple guide wheels. The pressing wheel 240 is elastic in the radial direction, and the outer peripheral surface of the pressing wheel 240 is used to press the tape 020 against the end surface of the edge of the plate body 010. In this embodiment, the axis of the pressing wheel 240 is parallel to the axes of the respective guide wheels. The function of the pressing wheel 240 is to provide an elastic abutting force, so that the middle region in the width direction of the tape 020 can be pressed against the end surface of the edge of the plate body 010, thereby achieving a firm adhesion. It should be understood that the end surface of the edge of the plate body 010 refers to the surface connecting the front and back surfaces of the plate body 010, and the normal vector of the end surface is perpendicular to the axes of the guide wheels and the pressing wheel 240; only relying on the action of the guide wheels, there may be a gap (i.e., not tightly adhered) between the middle region of the tape 020 and the end surface of the edge of the plate body 010, so the pressing wheel 240 is used to make the tape 020 closely fit the end surface of the plate body 010.

[0050] Optionally, the outer peripheral surface of the pressing wheel 240 can be made of an elastic material, such as polyurethane, rubber, etc.

[0051] Figure 4 It is an assembly schematic diagram of the pressing component 300 in an embodiment of the present application; Figure 5This is an exploded view of the pressing component 300 in an embodiment of the present application. As Figure 4 and Figure 5 shown, the pressing component 300 includes a pressing support 310, a first pressing roller 320, a second pressing roller 330, an elastic member 350, a movable member 340, and a guiding mechanism disposed on the pressing support 310. The elastic member 350 is used to apply an elastic force to the first pressing roller 320, so that the first pressing roller 320 has a tendency to approach the second pressing roller 330, thereby being able to clamp the edge of the plate body 010, and thus pressing the adhesive tapes 020 on both the front and back sides of the plate body 010, and at the same time being able to enhance the adaptability of the pressing component 300 to plate bodies 010 of different thicknesses.

[0052] Specifically, the movable member 340 is connected to the pressing support 310 through the guiding mechanism, the first pressing roller 320 is rotatably connected to the movable member 340, and the movable member 340 is movable relative to the pressing support 310; the second pressing roller 330 is rotatably connected to the pressing support, and its axis is fixed relative to the pressing support 310. The movable member 340 can approach or move away from the second pressing roller 330 under the guiding action of the guiding mechanism.

[0053] In this embodiment, the guiding mechanism includes a guiding column 341 and a guiding block 360. The guiding block 360 is disposed on the pressing support 310, and the guiding column 341 is disposed on the movable member 340; a guiding hole 361 is provided on the guiding block 360, and the guiding hole 361 is in plug-in fit with the guiding column 341, and the guiding column 341 can move axially relative to the guiding hole 361. One end of the elastic member 350 is fixed to the pressing support 310, and the other end abuts against the movable member 340. Specifically, in this embodiment, the guiding block 360 is fixedly connected to the pressing support 310 through a fastener (such as a screw), and the guiding column 341 is connected to the movable member 340. Optionally, the guiding column 341 can be threadedly connected to the movable member 340 for assembly and disassembly. By providing the sliding fit between the guiding column 341 and the guiding block 360, the movement direction of the movable member 340 can be defined, ensuring the stability of its movement.

[0054] Further, the pressing component 300 includes two parallel and spaced guiding columns 341, and the elastic member 350 is located between the two guiding columns 341. The pressing component 300 further includes a connecting rod 342. One end of the connecting rod 342 is connected to the movable member 340, and the other end passes through the guiding block 360. The elastic member 350 is a spring sleeved on the connecting rod 342. One end of the elastic member 350 abuts against the movable member 340, and the other end abuts against the guiding block 360. The connecting rod 342 not only guides the movable member 340, but also ensures the installation reliability of the elastic member 350. The connecting rod 342 can be threadedly connected to the movable member 340 to ensure stability and facilitate loading and unloading. Optionally, the connecting rod 342 is a screw. The front end of the screw can pass through the guiding block 360 and be connected to the movable member 340; the rear end of the screw is larger than the hole position of the guiding block 360 to form a limit, so that it can abut against the guiding block 360 to define the limit position where the first pressing roller 320 approaches the second pressing roller 330.

[0055] In this embodiment, the second pressing roller 330 is connected to the pressing member through the fixing block 370. Specifically, the fixing block 370 is fixedly connected to the pressing support 310 by screws, and the second pressing roller 330 is rotatably connected to the fixing block 370.

[0056] Optionally, the pressing support 310 is an L-shaped plate body, which includes two mutually perpendicular connecting plates. One of the connecting plates is fixed to the base 100 by at least two screws, and the fixing block 370 and the guiding block 360 are arranged on the other connecting plate.

[0057] The pressing component 300 in the embodiment of the present application can better squeeze the edge of the plate body 010 to ensure the reliability of the adhesive bonding of the tape 020. Moreover, when there are undulations on the surface of the plate body 010 or when sealing the edges of plate bodies 010 with different thicknesses, the position of the first pressing roller 320 can be adjusted adaptively, thereby improving the adaptability of the pressing component 300. In other optional embodiments, another elastic member can also be provided to apply an elastic force to the second pressing roller 330 so that the second pressing roller 330 has a tendency to approach the first pressing roller 320. For example, the second pressing roller 330 can also adopt the same setting method as the first pressing roller 320, and the two can jointly elastically clamp the edge of the plate body 010. Of course, only one elastic member can also be provided to drive the second pressing roller 330 so that it has a tendency to approach the first pressing roller 320.

[0058] Figure 6 It is an exploded view of the guiding component 400 in an embodiment of the present application. As Figure 6As shown, in the embodiment of the present application, the guiding component 400 is used to guide the plate body 010 to move towards the guiding wheel set 200. Along the movement path of the plate body 010, the guiding component 400 is located upstream of the guiding wheel set 200. The guiding component 400 includes a first guiding roller 420 and a second guiding roller 430 which are arranged in parallel at intervals. A channel for the plate body 010 to pass through is formed between the first guiding roller 420 and the second guiding roller 430. When edge-sealing, the edge of the plate body 010 first passes through the channel between the first guiding roller 420 and the second guiding roller 430. Therefore, the guiding component 400 can define the position of the plate body 010 relative to the tape edge-sealing device, enabling it to smoothly enter the guiding wheel set 200 and the pressing component 300 subsequently; at the same time, it can also ensure the stability of the position of the plate body 010 in the thickness direction when moving relative to the tape edge-sealing device.

[0059] Specifically in this embodiment, the guiding component 400 further includes a guiding support 410. The guiding support 410 is connected to the base 100. The first guiding roller 420 and the second guiding roller 430 are rotatably connected to the guiding support 410. In this embodiment, a strip-shaped hole 411 is provided on the guiding support 410. The first guiding roller 420 and the second guiding roller 430 are installed in the strip-shaped hole 411 and can adjust their positions along the strip-shaped hole 411, so that the distance width between the first guiding roller 420 and the second guiding roller 430 is adjustable. Therefore, the user can adjust the distance between the first guiding roller 420 and the second guiding roller 430 according to the thickness dimension of the plate body 010 to be edge-sealed, so that the guiding component 400 can better play the role of limiting and guiding.

[0060] Please refer to Figure 3 , furthermore, a handle 110 is also provided on the base 100 for the user to hold, so that it is convenient for the user to hold the tape edge-sealing device to perform the edge-sealing operation. Therefore, when the tape edge-sealing device provided in this embodiment is used, the plate body 010 can be fixed and the tape edge-sealing device can be moved to achieve edge-sealing.

[0061] When the tape edge-sealing device provided in the embodiment of the present application is used, the movement direction of the plate body 010 relative to the tape edge-sealing device should be consistent with the extension direction of its edge, as Figure 3As shown by the hollow arrow on the middle plate body 010. The plate body 010 first reaches the guiding assembly 400 and passes between the first guiding roller 420 and the second guiding roller 430. Then it reaches the first guiding wheel 210 of the guiding wheel group 200, is restricted by the limiting groove 211 of the first guiding wheel 210, and contacts and adheres to the adhesive surface of the tape 020 at the first guiding wheel 210. After that, the tape 020 and the edge of the plate body 010 pass through the second guiding wheel 220 and the third guiding wheel 230 together. Both sides of the tape 020 are guided to wrap the front and back sides of the plate body 010. When reaching the pressing wheel 240 subsequently, the pressing wheel 240 presses the tape 020 against the end surface of the edge of the plate body 010 to improve the adhesive effect between the tape 020 and the end surface. The edge of the plate body 010 and the tape 020 enter between the first pressing roller 320 and the second pressing roller 330 of the pressing assembly 300. The first pressing roller 320 and the second pressing roller 330 clamp the edge of the plate body 010 and tightly press both sides of the tape 020 in the width direction against the front and back sides of the plate body 010, so that finally the tape 020 tightly wraps the edge of the plate body 010. During the edge sealing process, the release film 021 on the tape 020 separates from the tape 020 at the second traction wheel 130, thereby exposing the adhesive surface of the tape 020. The release film 021 is wound and recycled on the release film recycling member 600.

[0062] In summary, the embodiment of the present application provides a tape edge sealing device. The tape edge sealing device includes a base 100 and a tape mounting member 500, a guiding wheel group 200, and a pressing assembly 300 provided on the base 100. The tape mounting member 500 is used for mounting and releasing the tape 020. The guiding wheel group 200 is used to abut against the tape 020 passing through the guiding wheel group 200 and guide the tape 020 to wrap the edge of the plate body 010. Along the movement path of the tape 020, the pressing assembly 300 is located downstream of the guiding wheel group 200. The pressing assembly 300 includes a first pressing roller 320 and a second pressing roller 330 arranged at intervals. The first pressing roller 320 and the second pressing roller 330 are used for clamping the edge of the plate body 010 to press the tape 020 tightly. In this embodiment, by providing the pressing assembly 300, when the edge of the plate body 010 passes through the pressing assembly 300, the first pressing roller 320 and the second pressing roller 330 can be used to clamp the edge of the plate body 010, thereby pressing the tape 020 that has already wrapped around the edge of the plate body 010 tightly, so that the tape 020 is more reliably adhered to the surface of the plate body 010. It can be seen that using the tape edge sealing device provided by the embodiment of the present application can improve the edge sealing effect and strengthen the protection of the edge of the plate body 010.
