Description

Technical Field

[0001] The present application relates to the technical field of plate edge banding processing, and in particular to a tape edge banding device. Background Art

[0002] When processing some panels, edge sealing is performed on the edges to protect the edges. Taking the edge sealing of the laminate in the photovoltaic module as an example, there is a solution of using tape for edge sealing, that is, sticking and wrapping the edge with tape to achieve a protective effect. In the related art, a tape packaging device is used to seal the edge of the board. After one edge of the board is sealed, the tape is cut off with a cutting tool (such as a cutter). Before the tape is cut, part of it is pasted on the edge of the board, and part of it is still coiled on the tape installation assembly. The tape is not easy to tighten. When the tape is cut with a cutting piece, a certain force will be applied to the tape. Because the tape is not tight enough and has poor stability, the tape is easily driven by the cutting piece, and the tape on the tape installation assembly is brought out. This situation brings inconvenience to the cutting of the tape and is also prone to waste of tape. Utility Model Content

[0047] Figure 1 This is a schematic diagram of a tape edge sealing device in one embodiment of the present application; Figure 2 This is a schematic diagram of an adhesive tape edge sealing device sealing the plate 010 in one embodiment of the present application. Figure 1 and Figure 2As shown, the tape edge sealing device provided in 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, so as to achieve protection. The plate body 010 can be a laminate in a photovoltaic module, or it can be other plate bodies 010 that need edge sealing for protection. The tape edge sealing device includes a base 100 and a tape installation assembly 500, a guide wheel group 200, a pressing assembly 300, a cutting assembly 700 and a braking assembly 600 arranged on the base 100. The tape installation assembly 500 is used to install the tape 020, and can be rotated relative to the base 100 to release the tape 020. The guide wheel group 200 is used to abut 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 adhesive tape 020, the pressing assembly 300 is located downstream of the guide wheel assembly 200. The pressing assembly 300 is used to press the adhesive tape 020 wrapped around the edge of the plate body 010 to make it firmly bonded. The cutting assembly 700 is used to cut the adhesive tape 020 downstream of the guide wheel assembly 200. The braking assembly 600 can controllably brake the adhesive tape installation assembly 500 to prevent the adhesive tape installation assembly 500 from releasing the adhesive tape 020.

[0048] The embodiment of the present application provides a cutting assembly 700 so that the user (such as an edge banding operator) can operate the cutting assembly 700 to cut the adhesive tape 020 after the edge banding of one edge of the plate 010 is completed. The brake assembly 600 is provided so that when the user cuts the adhesive tape 020, the brake assembly 600 can be controlled to brake the adhesive tape installation assembly 500 to prevent it from rotating to release the adhesive tape 020, so that the adhesive tape 020 can be tightened, thereby facilitating cutting. At the same time, it can also avoid waste caused by the adhesive tape 020 being released from the adhesive tape installation assembly 500 during cutting.

[0049] In addition, in the embodiment of the present application, the tape edge sealing device further includes a guide assembly 400 disposed on the base 100. The guide assembly 400 is used to guide the plate body 010 to move toward the guide wheel group 200. Along the movement path of the plate body 010, the guide assembly 400 is located upstream of the guide wheel group 200, and the guide assembly 400 includes a first guide roller 420 and a second guide roller 430 arranged in parallel and spaced apart, and a passage for the plate body 010 to pass through is formed between the first guide roller 420 and the second guide roller 430. When edge sealing is performed, the edge of the plate body 010 first passes through the passage between the first guide roller 420 and the second guide roller 430, so the guide assembly 400 can limit the position of the plate body 010 relative to the edge sealing device tape edge sealing device, so that it can subsequently smoothly enter the guide wheel group 200 and the pressing assembly 300; at the same time, it can also ensure the stability of the position of the plate body 010 in the thickness direction when it moves relative to the edge sealing device tape edge sealing device.

[0050] In this embodiment, a handle 110 is also provided on the base 100, so that the user can hold the tape edge sealing device to perform edge sealing operations. 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.

[0051] It should be understood that during the edge sealing operation, the tape 020 will move relative to the tape edge sealing device, and 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 010 will also move relative to the tape edge sealing device, and the movement path of the plate 010 refers to the movement path of the plate 010 relative to the tape edge sealing device with the tape edge sealing device as the reference. Of course, in actual use, the plate 010 can be fixed and the tape edge sealing device can move, or the tape edge sealing device can be fixed and the plate 010 can move.

[0052] The base 100 is a component used to support the tape installation assembly 500, the guide assembly 400, the guide wheel group 200, the cutting assembly 700, the braking assembly 600 and the pressing assembly 300. In the present embodiment, the base 100 is plate-shaped and has a certain strength. In other optional embodiments, the base 100 may be other shapes as long as it has the shape and strength to support and fix the relevant components of the tape edge sealing device.

[0053] Figure 3 An exploded view of a tape installation assembly 500 in one embodiment of the present application; Figure 4 FIG. 5 is a cross-sectional view of a tape installation assembly 500 in one embodiment of the present application. Figure 3 and Figure 4As shown, the tape installation assembly 500 includes a rotating shaft 510, a rotating disk 520, a chuck 530, an expansion sleeve 540 and a pressing plate 550. The rotating shaft 510 is fixedly installed on the base 100 and passes through the rotating disk 520, the chuck 530, the expansion sleeve 540 and the pressing plate 550. The rotating disk 520, the chuck 530, the expansion sleeve 540 and the pressing plate 550 are coaxially arranged, the chuck 530 and the rotating disk 520 are fixedly connected by screws, and the chuck 530 and the rotating shaft 510 are rotatably connected by a bearing 511, so that the chuck 530 and the rotating disk 520 can rotate relative to the base 100. The tape 020 can be wound around the outer peripheral side of the chuck 530. Specifically, a plurality of expansion parts 531 are arranged on the outer peripheral side of the chuck 530, and the plurality of expansion parts 531 are arranged at intervals around the circumference of the chuck 530. The inner side of the tape roll abuts against the outer side of each expansion part 531, and the tape roll can also be supported on the turntable 520 in the axial direction. The expansion sleeve 540 is connected to the chuck 530 by screws, and the outer peripheral side of the expansion sleeve 540 and the inner side of the expansion part 531 have mutually matching inclined surfaces, so that when the expansion sleeve 540 is pressed against the chuck 530 in the axial direction, the two mutually matching inclined surfaces slide against each other, so that the expansion part 531 has radially outward elastic deformation, thereby abutting against the inner side of the tape roll, so that the tape roll can be reliably fixed on the chuck 530.

[0054] In this embodiment, the tape installation assembly 500 further includes a spacer 512, a pressure plate 550 and a locking nut 560. The spacer 512 and the pressure plate 550 are both sleeved on the rotating shaft 510. The locking nut 560 is threadedly connected to the rotating shaft 510 and abuts against the pressure plate 550, so that the pressure plate 550 can press the spacer 512 in the axial direction. The spacer 512 abuts against the inner ring of the bearing 511 in the axial direction, so that the bearing 511 will not move in the axial direction. In addition, the pressure plate 550 also axially limits the chuck 530 so that it will not move in the axial direction. Optionally, the spacer 512 can be made of an elastic material, such as rubber.

[0055] 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 around the circumference of the guide wheel, and the guide groove 221 has two guide slopes spaced apart in the axial direction of the guide wheel, and the two guide slopes 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 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.

[0056] 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.

[0057] In this embodiment, the guide wheel group 200 includes a first guide wheel 210, a second guide wheel 220 and a third guide wheel 230. The outer peripheral side of the first guide wheel 210 is provided with a limiting groove 211, which is used to limit the axial position of the adhesive tape 020 relative to the first guide wheel 210. The second guide wheel 220 and the third guide wheel 230 are respectively provided with a guide groove 221. In this embodiment, the axes of the guide wheels are parallel. The limiting groove 211 of the first guide wheel 210 can position the adhesive tape 020 to ensure that it has a suitable position in the axial direction 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 respectively have two guide slopes spaced in the width direction of the guide grooves 221, which can guide the two sides of the adhesive tape 020 in the width direction to bend toward the front and back of the plate body 010, so that it has a tendency to wrap the edge of the plate body 010.

[0058] 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 adhesive tape 020, while the bottom width of the guide groove 221 on the second guide wheel 220 and the third guide wheel 230 should be smaller than the width of the adhesive tape 020, so that the guide slope can be pressed against both sides of the adhesive tape 020, so that the two sides of the adhesive tape 020 are bent toward the front and back of the plate body 010, thereby having a tendency to wrap the edge of the plate body 010. Optionally, the bottom width of the guide groove 221 can be equivalent to the thickness of the plate body 010.

[0059] Furthermore, the guide wheel group 200 further includes a clamping wheel 240, which is located downstream of the plurality of guide wheels along the movement path of the adhesive tape 020. The clamping wheel 240 is elastic in the radial direction, and the outer peripheral surface of the clamping wheel 240 is used to press the adhesive tape 020 against the end surface of the edge of the plate body 010. In this embodiment, the axis of the clamping wheel 240 is parallel to the axis of each guide wheel, and the function of the clamping wheel 240 is to provide an elastic resisting force, so that the middle area of ​​the adhesive tape 020 in the width direction can be pressed against the end surface of the edge of the plate body 010, thereby achieving a firm bond. It should be understood that the end face of the edge of the plate body 010 refers to the face connected between the front and back sides of the plate body 010, and the normal vector of the end face is perpendicular to the axis of the guide wheel and the pressure wheel 240; relying solely on the action of the guide wheel, there may be a gap between the middle area of ​​the tape 020 and the end face of the edge of the plate body 010 (i.e., they are not tightly bonded), so the pressure wheel 240 is used to enable the tape 020 to fit tightly to the end face of the plate body 010.

[0060] Optionally, the outer peripheral surface of the pressure wheel 240 may be made of elastic material, such as polyurethane, rubber, etc.

[0061] In this embodiment, the pressing assembly 300 is located downstream of the guide wheel group 200, and the pressing assembly 300 includes a pressing support 310 and a first pressing roller 320 and a second pressing roller 330 arranged at intervals on the pressing support 310. 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 tightly, so that the adhesive tape 020 wrapped around the edge of the plate body 010 can be firmly attached to the plate body 010. Further, an elastic member can also be provided in the pressing assembly 300 to apply elastic force to the first pressing roller 320 and / or the second pressing roller 330, so that the first pressing roller 320 and the second pressing roller 330 have a tendency to approach each other, so that the edge of the plate body 010 can be elastically clamped, so that the adhesive tape 020 on both sides of the plate body 010 can be pressed tightly, and at the same time, the adaptability of the pressing assembly 300 to plates 010 of different thicknesses can be enhanced. For example, the first pressing roller 320 is disposed on a sliding member, the sliding member can move relative to the pressing support 310, the two ends of the elastic member are respectively in contact with the sliding member and the pressing support 310, and the elastic force of the elastic member makes the first pressing roller 320 have a tendency to approach the second pressing roller 330. The elastic member can be a spring.

Figure 5 and Figure 6As shown, the brake assembly 600 includes a brake support 610, a first pusher 620 and a first brake 630. The first pusher 620 is movably disposed on the brake support 610. The first brake 630 is in transmission connection with the first pusher 620. The first pusher 620 is used to drive the first brake 630 to abut against the tape installation assembly 500 to achieve braking. In this embodiment, the brake support 610 includes a first mounting seat 611 and a first mounting plate 612, wherein the first mounting seat 611 is mounted on the base 100 by screws, and the first mounting plate 612 is mounted on the first mounting seat 611 by screws. The first pusher 620 is specifically in the shape of a rod, which is passed through the first mounting plate 612 and can move relative to the first mounting plate 612 in the axial direction.

[0063] The brake assembly 600 also includes a second brake member 640, which is in transmission connection with the first pusher 620. The first pusher 620 is used to drive the first brake member 630 and the second brake member 640 to clamp the tape installation assembly 500 together to achieve braking. Specifically in this embodiment, the first brake member 630 and the second brake member 640 are used to clamp the edge of the rotating disk 520 of the tape installation assembly 500, thereby achieving braking. In this embodiment, the first brake member 630 and the second brake member 640 are respectively provided with a first clamping pad 633 and a second clamping pad 643, and the first clamping pad 633 and the second clamping pad 643 can be made of elastic materials, such as rubber. The first clamping pad 633 and the second clamping pad 643 are used to abut against the rotating disk 520 when the first brake member 630 and the second brake member 640 clamp the rotating disk 520, thereby improving the braking force. In other optional embodiments, the brake assembly 600 can only include the first brake member 630, and the first brake member 630 is used to press against the tape installation assembly 500 to achieve braking.

[0064] Furthermore, the brake assembly 600 further includes a first guide member 650, a first slider 660, a first connecting rod 670 and a second connecting rod 680. The first guide member 650 is fixedly connected to the brake support 610. The first brake member 630 and the second brake member 640 are both slidably connected to the first guide member 650. The first brake member 630 and the second brake member 640 can be moved in a first direction (such as Figure 5 The first slider 660 is slidably connected to the first guide member 650 and can move relative to the first guide member 650 in a second direction (e.g. Figure 5 The first direction and the second direction are set at an angle, and the first pusher 620 is fixedly connected to the first slider 660. The two ends of the first connecting rod 670 are respectively rotatably connected to the first brake member 630 and the first slider 660, and the two ends of the second connecting rod 680 are respectively rotatably connected to the second brake member 640 and the first slider 660. In this embodiment, the first direction and the second direction are perpendicular.

[0065] Specifically, the brake assembly 600 includes two first guide members 650 spaced apart, a first slider 660 is disposed between the two first guide members 650; a first guide pin 632 and a second guide pin 642 are connected between the two first guide members 650; a first strip hole 631 extending along the first direction is disposed on the first brake member 630, and a second strip hole 641 extending along the first direction is disposed on the second brake member 640; the first brake member 630 is plugged with the first guide pin 632 through the first strip hole 631, and the second brake member 640 is plugged with the second guide pin 642 through the second strip hole 641. In this embodiment, the two first guide members 650 are in the third direction (i.e. Figure 5 The first guide pin 632, the second guide pin 642, the first strip hole 631 and the second strip hole 641 are provided to enable the first brake member 630 and the second brake member 640 to slide relative to the first guide member 650 in the first direction. The two first guide members 650 are provided to make the sliding motion of the first brake member 630, the second brake member 640 and the first slider 660 more reliable. In other optional embodiments, the sliding connection may be achieved by using a sliding groove and a slider instead of using a strip hole and a guide pin to achieve the sliding connection.

[0066] In this embodiment, the number of the first connecting rods 670 is at least two, and at least two first connecting rods 670 are arranged at intervals in the second direction, and the first connecting rods 670 are parallel to each other. In this way, when the first connecting rod 670 drives the first brake member 630 to move along the first direction, the first brake member 630 is not easy to rotate and can reliably perform translational movement. Similarly, in this embodiment, the number of the second connecting rods 680 is at least two, and at least two second connecting rods 680 are arranged at intervals in the second direction. In this embodiment, the number of the first connecting rod 670 and the number of the second connecting rod 680 are both two.

[0067] In this embodiment, the first slider 660 is provided with a first guide boss 661 on two opposite sides in the third direction, and the two first guide members 650 are provided with a first slide groove 651, which extends along the second direction. The two first guide bosses 661 are respectively slidably matched with the two first slide grooves 651, so that the first slider 660 can slide relative to the first guide member 650 in the second direction. Specifically, in this embodiment, the first guide boss 661 is a strip boss extending along the second direction, so that the first slider 660 will not rotate and can maintain translation.

[0068] When the tape installation assembly 500 needs to be braked, it is only necessary to brake along the second direction (specifically Figure 5The first push member 620 is pushed in the direction (in the middle c direction), and the first slider 660 moves in the second direction. The first connecting rod 670 and the second connecting rod 680 pull the first brake member 630 and the second brake member 640 to move. Due to the limiting effect of the first strip hole 631 and the second strip hole 641, the first brake member 630 and the second brake member 640 can only approach each other in the first direction to achieve clamping braking. If the brake needs to be released, only the first push member 620 needs to be reversed (specifically, Figure 5 Just move in the direction (d).

[0069] In this embodiment, the two ends of the first push member 620 are respectively located on opposite sides of the first mounting plate 612, one end of which is connected to the first slider 660, and the other end is provided with a ball head 622, which is used to cooperate with the transmission structure provided on the cutting assembly 700.

[0070] In this embodiment, the brake assembly 600 further includes a first elastic reset member 621, which is used to provide a reset force to the first push member 620, so that the brake assembly 600 can automatically release the brake. In this embodiment, the first elastic reset member 621 is a compression spring sleeved on the first push member 620.

[0071] Figure 7 This is a schematic diagram of the assembly of a cutting assembly 700 in one embodiment of the present application; Figure 8 FIG. 7 is an exploded view of a cutting assembly 700 in one embodiment of the present application. Figure 7 and Figure 8 As shown, the cutting assembly 700 includes a cutting support 710, a second pusher 720 and a cutting piece 730, wherein the second pusher 720 is movably disposed on the cutting support 710, and the cutting piece 730 is transmission-connected with the second pusher 720, and the second pusher 720 is used to drive the cutting piece 730 to move so as to cut the adhesive tape 020. Specifically in this embodiment, the cutting support 710 includes a second mounting seat 711 and a second mounting plate 712, wherein the second mounting seat 711 is mounted on the base 100 by screws, and the second mounting plate 712 is mounted on the second mounting seat 711 by screws. The second pusher 720 is specifically in the shape of a rod, which is passed through the second mounting plate 712 and can move relative to the second mounting plate 712 along its own axial direction.

[0072] In this embodiment, the cutting member 730 is a cutting knife, and the cutting member 730 can perform translational motion along with the second pushing member 720 , thereby achieving cutting of the adhesive tape 020 .

[0073] In this embodiment, the cutting assembly 700 further includes a second guide member 740 and a second slider 750. There are two second guide members 740, which are fixedly mounted on the same surface of the second mounting plate 712 by screws and spaced apart from each other. The second slider 750 is located between the two second guide members 740 and slides with the two second guide members 740. Specifically, two second slide grooves 741 are respectively provided on the second guide member 740, and the extension direction of the second slide grooves 741 is consistent with the axial direction of the second pusher 720. Second guide bosses 751 are respectively provided on opposite sides of the second slider 750, and the two second guide bosses 751 slide with the two second slide grooves 741 respectively. The two ends of the second pusher 720 are respectively located on opposite sides of the second mounting plate 712, and one end thereof is connected to the second slider 750. The cutting member 730 is fixedly arranged on the second slider 750. It can be seen that by pushing the second pusher 720, the translational movement of the cutting piece 730 can be achieved, and the two second guide members 740 increase the stability of the cutting piece 730 during the cutting movement. In this embodiment, the second guide boss 751 is a strip boss and extends along the axial direction of the second pusher 720, so that the second slider 750 is not easy to rotate, thereby ensuring its translational movement.

[0074] In this embodiment, the cutting assembly 700 further includes a second elastic reset member 721, which is used to provide a reset force to the second pusher 720, so that the cutting member 730 can automatically reset after the tape 020 is cut. In this embodiment, the second elastic reset member 721 is a compression spring sleeved on the second pusher 720.

[0075] Furthermore, the second pusher 720 is connected to the first pusher 620 through a transmission structure. When the second pusher 720 drives the cutting member 730 to perform cutting movement, the transmission structure synchronously drives the first pusher 620 to move so that the brake assembly 600 brakes the tape installation assembly 500. By setting the transmission structure, when the user uses the cutting assembly 700 to cut the tape 020, the brake assembly 600 can synchronously brake the tape installation assembly 500 under the action of the transmission structure, and the user does not need to operate the brake assembly 600 additionally, thereby improving convenience.

[0076] In an optional embodiment, the transmission structure includes a transmission block 760, which is disposed at one end of the second pusher 720 away from the cutting member 730. The transmission block 760 is provided with a guide slope 761 and a contact surface 762 connected to the guide slope 761. The guide slope 761 is inclined to the pushing direction of the second pusher 720 and to the pushing direction of the first pusher 620, and the contact surface 762 is parallel to the pushing direction of the second pusher 720. When the second pusher 720 drives the cutting member 730 to perform cutting movement, the guide slope 761 is used to contact the first pusher 620 and slide relative to the first pusher 620, so that the first brake member 630 (and the second brake member 640) are close to the tape installation assembly 500. When the contact surface 762 contacts the first pusher 620, the brake assembly 600 brakes the tape installation assembly 500. In this embodiment, the ball head 622 on the first pusher 620 is brought into contact with the guide inclined surface 761 or the contact surface 762 to reduce the friction resistance through point contact.

[0077] Fig. 9 This is a partial schematic diagram of a tape edge sealing device before cutting in one embodiment of the present application; Fig.10 This is a schematic diagram of the cooperation between the brake assembly 600 and the tape installation assembly 500 before cutting in one embodiment of the present application. Fig. 9 , Fig.10 As shown, before cutting, the second pusher 720 has not yet pushed the cutting member 730 , the guide slope 761 of the transmission block 760 has not yet pushed the first pusher 620 for braking, and the first brake member 630 and the second brake member 640 of the brake assembly 600 have not clamped the turntable 520 .

[0078] Fig.11 This is a partial schematic diagram of a tape edge sealing device during a cutting process in one embodiment of the present application; Fig.12 FIG. 6 is a schematic diagram of the cooperation between the brake assembly 600 and the tape installation assembly 500 during the cutting process in one embodiment of the present application. Fig.11 and Fig.12 As shown, after the edge banding is completed, in the process of pushing the second pusher 720 for cutting, the transmission block 760 and the second pusher 720 move in the same direction, the guide slope 761 abuts against the ball head 622 at the end of the first pusher 620, and relative sliding occurs, so that the first pusher 620 moves under the push of the transmission block 760. The movement of the first pusher 620 drives the first slider 660 to move, and then drives the first brake member 630 and the second brake member 640 to clamp the rotating disk 520, as shown in FIG. Fig.12 As shown. Fig.11 and Fig.12It can be seen that before the cutting piece 730 contacts and cuts the tape 020 , the brake assembly 600 has braked the tape installation assembly 500 . At this time, the tape installation assembly 500 can no longer release the tape 020 , and the tape 020 can be tightened.

[0079] Fig.13 This is a partial schematic diagram of the tape edge sealing device in one embodiment of the present application when cutting is completed. Fig.13 As shown, the second pusher 720 continues to push the cutting member 730 to cut the tape 020. At the same time, the ball head 622 on the first pusher 620 passes over the guide slope 761 and abuts against the abutment surface 762. When the ball head 622 abuts against the abutment surface 762, the first brake member 630 and the second brake member 640 keep clamping the rotating disk 520.

[0080] After that, the user releases the second pusher 720, and the second pusher 720 performs a reset motion under the push of the second elastic reset member 721, and the transmission block 760 also moves synchronously with the second pusher 720. After the ball head 622 loses contact with the abutment surface 762, the first pusher 620 performs a reset motion under the elastic force of the first elastic reset member 621, and the ball head 622 slides along the guide inclined surface 761 of the transmission block 760, and finally the first pusher 620 and the second pusher 720 complete the reset. The reset motion of the first pusher 620 causes the first brake member 630 and the second brake member 640 to release the rotating disk 520, thereby releasing the brake on the tape installation assembly 500.

[0081] In summary, the embodiment of the present application provides a tape edge sealing device, which includes a base 100 and a tape installation assembly 500, a guide wheel group 200, a cutting assembly 700 and a brake assembly 600 arranged on the base 100. The tape installation assembly 500 is used to install the tape 020, and the tape installation assembly 500 can rotate relative to the base 100 to release the tape 020. The guide wheel group 200 is used to abut the tape 020 passing through the guide wheel group 200, and guide the tape 020 to wrap the edge of the plate body 010. The cutting assembly 700 is used to cut off the tape 020 downstream of the guide wheel group 200. The brake assembly 600 can controllably brake the tape installation assembly 500 to prevent the tape installation assembly 500 from releasing the tape 020. In this embodiment, since the brake assembly 600 is provided on the tape edge sealing device, when the tape 020 needs to be cut after the edge sealing is completed, the brake assembly 600 can be controlled to brake the tape installation assembly 500 to prevent it from releasing the tape 020 due to rotation. When the brake assembly 600 is used to brake the tape installation assembly 500, the tape installation assembly 500 cannot release the tape 020, so the tape 020 can be tightened, making it easier to cut, and it is not easy to cause waste of the tape 020.
