DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but merely represents selected embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the scope of protection of the present application.

[0038] It should be noted that like reference numerals and letters denote like items in the following drawings. Therefore, once an item is defined in one drawing, it does not require further definition and explanation in subsequent drawings.

[0039] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed during use.

[0042] Figure 1 It is a schematic diagram of the tape edge-sealing device in the first embodiment of the present application from the first perspective; Figure 2 It is a schematic diagram of the tape edge-sealing device in the first embodiment of the present application from the second perspective; Figure 3 It is a schematic diagram when the tape edge-sealing device in the first embodiment of the present application seals the plate body 010. As Figures 1 to 3As shown in the figure, 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 require edge sealing for protection. The tape edge-sealing device includes a base 100 and a tape mounting member 500, a guide wheel group 200, a pressing component 300, and a cutting component 700 provided on the base 100. The tape mounting member 500 is used to install and release the tape 020. The guide wheel group 200 is used to abut against the tape 020 passing through the guide 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 component 300 is located downstream of the guide wheel group 200. The pressing component 300 is used to press the tape 020 wrapped around the edge of the plate body 010 to make it firmly adhered. The cutting component 700 includes a driving structure 720 and a cutting member that can move relative to the base 100. Along the movement path of the tape 020, the cutting member is located downstream of the guide wheel group 200. The driving structure 720 is used to drive the cutting member to move to cut the tape 020.

[0043] In the embodiment of the present application, by providing the cutting component 700, the edge-sealing operator can operate the driving structure 720 to make the cutting member cut the tape 020 after the edge sealing of one edge of the plate body 010 is completed. Since the operations of edge sealing and cutting are both completed by the tape edge-sealing device, the operator does not need to take additional tools to cut the tape 020, so it brings convenience to the edge-sealing operation.

[0044] 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 to wind and recycle 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 group 200.

[0045] 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 the 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 the 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.

[0046] The base 100 is a component for carrying the tape mounting member 500, the release liner recycling member 600, the guiding assembly 400, the guide wheel set 200, and the pressing assembly 300. In this embodiment, the base 100 is plate-shaped 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.

[0047] The following introduces each component on the base 100 in the order from upstream to downstream according to the movement path of the tape 020.

[0048] The tape mounting member 500 is rotatably mounted on the base 100, and 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).

[0049] 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 by 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.

[0050] 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 member 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 transmission belt 610 and the second traction wheel 130, 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.

[0051] 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. The outer peripheral side of at least part of the guide wheels has a guide groove 221 extending circumferentially around the guide wheel, 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 the guide slope 222 is used to guide the adhesive tape 020 to wrap around the edge of the plate body 010 when the guide groove 221 rolls relative to the plate body 010.

[0052] 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.

[0053] 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 both 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.

[0054] 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 both 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.

[0055] 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 plurality of guide wheels. The pressing wheel 240 is elastic in the radial direction. 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. Therefore, the pressing wheel 240 is used to make the tape 020 closely fit the end surface of the plate body 010.

[0056] Optionally, the outer peripheral surface of the pressing wheel 240 can be made of an elastic material, such as polyurethane, rubber, etc.

[0057] Figure 4 It is an assembly schematic diagram of the pressing component 300 and the cutting blade plate 711 in an embodiment of the present application. As Figure 4As shown, in this embodiment, the pressing component 300 includes a first pressing roller 320 and a second pressing roller 330 that are spaced apart. 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 adhesive tape 020. By providing 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 adhesive tape 020 that has been wrapped around the edge of the plate body 010, making the adhesive tape 020 more reliably adhered to the surface of the plate body 010.

[0058] Specifically, the pressing component 300 includes a pressing support 310, and a first pressing roller 320, a second pressing roller 330, an elastic member 350, a movable member 340, a guide post 341, and a guide block 360 provided 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, so as to press the adhesive tape 020 on both the front and back sides of the plate body 010, and at the same time, it can also enhance the adaptability of the pressing component 300 to plate bodies 010 of different thicknesses.

[0059] Specifically, the first pressing roller 320 is rotatably connected to the movable member 340, and the movable member 340 can move relative to the pressing support 310; the second pressing roller 330 is rotatably connected to the pressing support 310, and its axis is fixed relative to the pressing support 310.

[0060] Optionally, one of the guide block 360 and the guide post 341 is provided on the pressing support 310, and the other is provided on the movable member 340; a guide hole 361 is provided on the guide block 360, and the guide hole 361 is slidably matched with the guide post 341. 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 guide block 360 is fixedly connected to the pressing support 310 through a fastener (such as a screw), and the guide post 341 is connected to the movable member 340. Optionally, the guide post 341 can be threadedly connected to the movable member 340 for easy assembly and disassembly. By providing the sliding fit between the guide post 341 and the guide block 360, the movement direction of the movable member 340 can be limited to ensure the stability of its movement.

[0061] Further, the pressing assembly 300 includes two parallel and spaced guiding columns 341, and the elastic member 350 is located between the two guiding columns 341. The pressing assembly 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, so as 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 of the first pressing roller 320 approaching the second pressing roller 330.

[0062] In this embodiment, the second pressing roller 330 is connected between the pressing supports 310 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.

[0063] Optionally, the pressing support 310 includes two mutually perpendicular connecting plates, so that the pressing support 310 is in an L shape. One of the connecting plates of the pressing support 310 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.

[0064] The pressing assembly 300 in the embodiment of the present application can better extrude the edge of the plate body 010 to ensure the reliability of the 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, so as to improve the adaptability of the pressing assembly 300. In other alternative embodiments, the second pressing roller 330 can also have a tendency to move towards the first pressing roller 320 under the action of another elastic member 350. 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.

[0065] Figure 5 It is an assembly schematic diagram of the base 100, the cutting assembly 700, and the pressing assembly 300 in the first perspective in the first embodiment of the present application; Figure 6 It is an assembly schematic diagram of the base 100, the cutting assembly 700, and the pressing assembly 300 in the second perspective in the first embodiment of the present application. As Figure 5 and Figure 6As shown, in this embodiment, the cutting piece includes a cutter 710 , and the driving structure 720 is used to drive the cutter 710 to rotate to cut the tape 020 .

[0066] Further, the driving structure 720 includes a rotating shaft 721 and a rotating shaft support 722, the rotating shaft support 722 is fixed relative to the base 100, the rotating shaft 721 is rotatably connected to the rotating shaft support 722, and one end of the rotating shaft 721 is connected to the cutter 710, and the rotating shaft 721 drives the cutter 710 to perform a cutting motion by rotating. The operator can drive the rotating shaft 721 to rotate, thereby driving the cutter 710 to perform a cutting motion. It should be understood that in this embodiment, the cutting motion of the cutter 710 refers to the rotation of its cutting edge forward so that the cutting edge can cut the adhesive tape 020. In this embodiment, the number of the rotating shaft support 722 is two, one of which is fixedly mounted on the base 100, and the other rotating shaft support 722 is fixedly mounted on the pressing support 310 of the pressing assembly 300, and is located on the side of the pressing support 310 away from the first pressing roller 320 and the second pressing roller 330. The stability of the rotating shaft 721 and the cutter 710 can be ensured by the two rotating shaft supports 722. In other optional embodiments, the cutter 710 can also be configured to perform cutting motion by translation. For example, the end of the rotating shaft 721 close to the cutter 710 is connected to the cutter 710 through another gear-rack structure, and the cutter 710 and the rack fixedly connected thereto can translate relative to the base 100, and the gear at the end of the rotating shaft 721 is meshed with the rack on the cutter 710. In this way, the rotating shaft 721 can convert its own rotation into the translation motion of the cutter 710 through the gear-rack structure, thereby achieving cutting.

[0067] Furthermore, the driving structure 720 further includes a sliding member 724, which is slidably connected to the base 100, a gear 723 is provided on the rotating shaft 721, a rack 725 is provided on the sliding member 724, the gear 723 is meshed with the rack 725, and the sliding member 724 can move along a first direction relative to the base 100 to drive the cutter 710 to perform a cutting movement. It may be inconvenient for the operator to directly rotate the rotating shaft 721, so the sliding member 724, the gear 723, and the rack 725 are provided, so that the operator can drive the rotating shaft 721 to rotate by pushing the sliding member 724 to translate along the first direction, thereby driving the cutter 710 to perform a cutting movement. The sliding member 724 and the base 100 can be slidably connected in a sliding rail-slider manner, for example, the sliding rail is a dovetail groove provided on the base 100, and the slider is provided on the sliding member 724 and cooperates with the dovetail groove.

[0068] Furthermore, the driving structure 720 further includes a reset elastic member 730, which is used to drive the sliding member 724 to move in a second direction to drive the cutter 710 to perform a reset movement, and the second direction is opposite to the first direction. It should be understood that the reset movement has a movement direction opposite to the cutting movement. By providing the reset elastic member 730, the cutter 710 can be automatically reset after the cutting is completed so as to perform the next cutting.

[0069] Furthermore, a limiting seat 727 is also provided on the base 100, and the limiting seat 727 is used to abut the sliding member 724 after the cutter 710 is reset to prevent the sliding member 724 from moving in the second direction. By providing the limiting seat 727, it is possible to prevent the sliding member 724 from excessively moving in the second direction under the action of the reset elastic member 730. In this embodiment, the reset elastic member 730 is a spring, a spring seat 731 is provided on the base 100, and an abutting portion 726 is convexly provided on the sliding member 724, one end of the spring abuts against the abutting portion 726, and the other end abuts against the spring seat 731. Furthermore, one of the abutting portion 726 and the spring seat 731 can be provided with a guide column, and the other can be provided with a through hole, the guide column and the through hole are plugged together, and the spring is sleeved on the guide column to ensure the stability of the spring itself. In this embodiment, a toggle portion 728 is protruding from the sliding member 724 , and the toggle portion 728 may be a pin shaft, so that an operator can toggle the sliding member 724 to control the cutter 710 to perform cutting.

[0070] Furthermore, the cutting assembly 700 further includes a cutting blade 711 fixed relative to the base 100. The cutter 710 can slide on the cutting blade 711 during the cutting movement, thereby cutting the tape 020 together with the cutting blade 711. Specifically in this embodiment, the cutting blade 711 is disposed on the pressing support 310 (such as Figure 4 When the cutter 710 performs the cutting motion, the cutting edge of the cutter 710 can clamp the adhesive tape 020 with the cutting blade 711 and cut the adhesive tape 020 .

[0071] Figure 7 This is a schematic diagram of the assembly of the base 100 and the cutting assembly 700 in the second embodiment of the present application at a first viewing angle; Figure 8 This is a schematic diagram of the assembly of the base 100 and the cutting assembly 700 in the second embodiment of the present application at a second viewing angle; Figure 9 FIG. 7 is an exploded view of the cutting assembly 700 in the second embodiment of the present application. Figures 7 to 9 As shown, in this embodiment, the cutting piece includes a pair of scissors 740, and the scissors 740 include a first shearing piece 741 and a second shearing piece 742 that are cross-arranged and can rotate relative to each other. The driving structure 720 is transmission-connected to the first shearing piece 741 and the second shearing piece 742, and is used to drive the first shearing piece 741 and the second shearing piece 742 to rotate relative to each other to cut the tape 020.

[0072] Furthermore, a scissor support 743 is provided on the base 100. Both the first shearing member 741 and the second shearing member 742 are rotatably connected to the scissor support 743 and their rotation axes coincide. The driving structure 720 includes a push rod 750 and a push rod support 755. The push rod 750 is rotatably connected to the push rod support 755. Both the first shearing member 741 and the second shearing member 742 are rotatably connected to the push rod 750. The push rod 750 has a first rotation direction and a second rotation direction relative to the push rod support 755. When the push rod 750 rotates along the first rotation direction, it can drive the scissors 740 to close to cut the tape 020. When the push rod 750 rotates along the second rotation direction, it can drive the scissors 740 to open. The first rotation direction is opposite to the second rotation direction.

[0073] Figure 10 It is a schematic diagram of the scissors 740 of the cutting assembly 700 in the second embodiment of the present application being opened; Figure 11 It is a schematic diagram of the scissors 740 of the cutting assembly 700 in the second embodiment of the present application being closed. Combining Figures 7 to 11 As shown, in this embodiment, the push rod 750 has opposite first end 751 and second end 752. The first end 751 of the push rod 750 is connected to the first shearing member 741 through a first connecting member 753. The connection position of the first connecting member 753 and the first shearing member 741 is the first hinge point M. The first hinge point M and the cutting edge of the first shearing member 741 are on the same side of the rotation axis of the first shearing member 741 (that is, the first hinge point M is between the cutting edge of the first shearing member 741 and the rotation axis of the first shearing member 741). In Figure 10 both the first hinge point M and the cutting edge of the first shearing member 741 are on the left side of the rotation axis of the first shearing member 741. Furthermore, the part between the first end 751 of the push rod 750 and the rotation axis of the push rod 750 is connected to the second shearing member 742 through a second connecting member 754. The connection position of the second connecting member 754 and the second shearing member 742 is the second hinge point. The second hinge point N and the cutting edge of the second shearing member 742 are on both sides of the rotation axis of the second shearing member 742 respectively (that is, the rotation axis of the second shearing member 742 is between the second hinge point N and the cutting edge of the second shearing member 742). In Figure 10 both the second hinge point N and the cutting edge of the second shearing member 742 are on the left and right sides of the rotation axis of the second shearing member 742 respectively.

[0074] See Figure 10 and Figure 11When the push rod 750 rotates along the first rotation direction (W1 direction in the figure), the first connecting member 753 drives the first shearing member 741 to rotate clockwise, and the second connecting member 754 drives the second shearing member 742 to rotate counterclockwise, so that the edges of the first shearing member 741 and the second shearing member 742 are close to each other, that is, the scissors 740 are closed, and the tape 020 can be cut in this process. When the push rod 750 rotates along the second rotation direction (W2 direction in the figure), the first connecting member 753 drives the first shearing member 741 to rotate counterclockwise, and the second connecting member 754 drives the second shearing member 742 to rotate clockwise, so that the edges of the first shearing member 741 and the second shearing member 742 are away from each other, that is, the scissors 740 are opened.

[0075] In this embodiment, the driving structure 720 further includes a reset elastic member 730, which is used to drive the push rod 750 to rotate along the second rotation direction to drive the scissors 740 to open. By providing the reset elastic member 730, the scissors 740 can automatically open and prepare for the next cutting after the shearing is completed, thereby improving the cutting efficiency. In this embodiment, the reset elastic member 730 is a tension spring, one end of which is connected to the hole of the push rod 750, and the other end is connected to the spring seat 731 on the base 100.

[0076] In this embodiment, the second end 752 of the push rod 750 is provided with a toggle member 760, and the operator can toggle the push rod 750 to rotate through the toggle member 760, so as to cut the tape 020. The toggle member 760 can be a pin. In order to reduce the movement stroke of the toggle member 760 and thus reduce the operating range of the operator, optionally, the distance from the second end 752 to the rotation axis of the push rod 750 is smaller than the distance from the second end 752 to the rotation axis of the push rod 750.

[0077] Figure 12 This is a schematic diagram of the second embodiment of the present application when the tape edge sealing device is edge sealing the plate 010. Figure 3 and Figure 12As shown in the figure, the tape edge-sealing device provided by the embodiment of the present application is further provided with a guiding component 400, and 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, and 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, so that it can 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.

[0078] Furthermore, a handle 110 is further 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 by this embodiment is used, the plate body 010 can be fixed, and the tape edge-sealing device can be moved to achieve edge-sealing.

[0079] When the tape edge-sealing device provided by 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 set 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, and 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 face of the edge of the plate body 010 to improve the adhesive effect between the tape 020 and the end face. 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 is separated 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. After the edge sealing is completed, the driving structure 720 can be manually operated to control the cutting member (such as the cutter 710 or the scissors 740) to cut the tape 020. The whole edge sealing process is efficient and reliable.

For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
