Description

Technical Field

[0001] The present application relates to the technical field of batteries, and more specifically, to a sealing edge peeling device and a battery production system. Background Art

[0002] At the connection between the upper cover and the lower box body of the battery box, processes such as hemming are required for sealing. When quality problems occur after sealing, it is necessary to peel and rework the sealed connection.

[0003] The related art peels the sealed connection by manually holding tools, with low efficiency. Therefore, how to improve the peeling efficiency is a research direction in battery technology. Summary of the Utility Model

[0004] The present application provides a sealing edge peeling device and a battery production system, which can improve the peeling efficiency of the sealed connection between the upper cover and the lower box body.

[0005] In a first aspect, an embodiment of the present application provides a sealing edge peeling device, including a traveling mechanism and a peeling member. The traveling mechanism is configured to clamp the sealing edge and travel along the extending direction of the sealing edge; the peeling member is connected to the traveling mechanism and is provided with an insertion portion for inserting into the connection seam of the sealing edge, and the insertion portion is configured to peel the sealing edge under the driving of the traveling of the traveling mechanism.

[0006] By adopting the above technical solution, the sealing edge peeling device is designed to include a traveling mechanism and a peeling member. The traveling mechanism can travel along the extending direction of the sealing edge, thereby driving the peeling member inserted into the connection seam to peel the sealing edge, and continuous linear peeling operation of the sealed connection can be realized. Compared with the method of manually holding tools, the peeling efficiency and the accuracy of the action are higher, and the risk of damaging the sealed connection can also be reduced.

[0007] In some embodiments of the present application, the traveling mechanism includes a first side facing the sealing edge and a second side facing away from the sealing edge. Along the arrangement direction from the traveling mechanism to the peeling member, the insertion portion faces the traveling mechanism and has a gap with the traveling mechanism. Along the direction away from the traveling mechanism, the dimension of the insertion portion gradually increases in a first direction, and the first direction intersects the arrangement direction from the traveling mechanism to the peeling member and intersects the arrangement direction from the first side to the second side.

[0008] With the above technical solution, the peeling member is designed to include an insertion portion for inserting into the connection seam, and the insertion portion is designed as a wedge-shaped structure with a gradually increasing size in the direction away from the traveling mechanism. Thus, during the process of traveling with the traveling mechanism, the insertion portion can gradually increase the angle between the lifted portion of the second sealing portion and the second sealing portion, which not only facilitates the disconnection of the first sealing portion and the second sealing portion, but also reduces the possibility of damaging the first sealing portion and the second sealing portion.

[0009] In some embodiments of the present application, the insertion portion includes a first surface and a second surface arranged oppositely along the first direction. The sealing edge includes a first sealing portion and a second sealing portion that wraps at least part of the first sealing portion. The first surface is used to abut against the second sealing portion, and the second surface is used to abut against the first sealing portion. One end of the first surface facing the traveling mechanism and one end of the second surface facing the traveling mechanism are connected to form a tip. Along the direction away from the traveling mechanism, the distance between the first surface and the second surface in the first direction gradually increases.

[0010] With the above technical solution, one end of the insertion portion facing the traveling mechanism is designed as a tip, so as to facilitate the insertion of the insertion portion into the connection seam. This not only facilitates the insertion portion to lift the second sealing portion that wraps the first sealing portion, but also can reduce the possibility of abrasion with the first sealing portion and the second sealing portion to a certain extent.

[0011] In some embodiments of the present application, the traveling mechanism includes a first side for facing the sealing edge and a second side for facing away from the sealing edge. The first surface has a first edge and a second edge arranged oppositely along the second direction. The second direction is the arrangement direction from the first side to the second side. The first edge, the second edge, and the second side are arranged in sequence along the second direction. From the first edge to the second edge, the distance between the first surface and the second surface in the first direction gradually decreases.

[0012] With the above technical solution, the first surface is designed as a guiding surface that is an inclined surface or a curved surface. Thus, during the movement of the peeling member, the angle between the lifted portion of the second sealing portion by the peeling member and the first sealing portion gradually increases, and it can gradually move away from the first sealing portion along the guidance of the first sealing portion, which is more convenient for the second sealing portion to disengage from the first sealing portion, and reduces the possibility of excessive deformation of the second sealing portion due to excessive lifting angle and force.

[0013] In some embodiments of the present application, the walking mechanism includes a first side facing the sealing edge and a second side facing away from the sealing edge. The peeling member further includes a spreading portion, and the spreading portion is connected to an end of the insertion portion facing away from the walking mechanism. Along a second direction, the minimum dimension of the spreading portion is greater than the maximum dimension of the insertion portion, and the second direction is the arrangement direction from the first side to the second side.

[0014] With the above technical solution, the peeling member is designed to further include a spreading portion. When the insertion portion spreads and separates a second sealing portion, as the peeling member walks, the spreading portion is in guiding cooperation with the lifted second sealing portion, and the second sealing portion is further lifted along the second direction, so that the second sealing portion can be further separated from the first sealing portion.

[0015] In some embodiments of the present application, the spreading portion includes a third surface and a fourth surface arranged oppositely along the first direction, and a fifth surface and a sixth surface arranged oppositely along the second direction. The third surface is connected to the first surface, the fourth surface is connected to the second surface, the fifth surface, the sixth surface and the second side are arranged in sequence along the second direction. The sixth surface intersects with the third surface to form a third edge, and the sixth surface intersects with the fourth surface to form a fourth edge. The cross-section of the spreading portion in a plane parallel to the first direction and the second direction includes a first side edge, a second side edge and a third side edge connected at an angle in sequence. The first side edge is located on the third surface, the second side edge is located on the sixth surface, and the third side edge is located on the fourth surface. From the end of the spreading portion facing the walking mechanism to the end facing away from the walking mechanism, the included angle between the first side edge and the second side edge gradually decreases, and the included angle between the second side edge and the third side edge gradually increases.

[0016] With the above technical solution, the sixth surface can form a gradually changing curved surface structure, and the distance between the third edge and the second side along the second direction gradually decreases in the direction away from the walking mechanism. Furthermore, during the walking process of the spreading portion along with the walking mechanism, the second sealing portion in contact with the third edge and lifted gradually moves away from the first sealing portion along the second direction, gradually increasing the angle between the lifted second sealing portion and the first sealing portion. Moreover, the possibility of damage to the second sealing portion can be reduced. The distance between the fourth edge and the second side along the second direction remains unchanged, which can reduce the possibility of contact between the fourth edge and the lifted second sealing portion, thereby reducing the resistance during the walking process of the spreading portion.

[0017] In some embodiments of the present application, the third edge is an arc transition structure.

[0018] With the above technical solution, designing the third edge as an arc transition structure can enable the third edge to better guide the second sealing portion to deform along a preset direction, reducing the possibility of scratching the second sealing portion after the third edge contacts the second sealing portion; designing the fourth edge as an arc transition structure can enable the fourth edge to play a guiding role once it contacts the side of the second sealing portion close to the first sealing portion that is being lifted, and can also reduce the possibility of scratching the second sealing portion after the fourth edge contacts the second sealing portion.

[0019] In some embodiments of the present application, from the end of the spreading portion facing the traveling mechanism to the end away from the traveling mechanism, the angle between the second side and the third side gradually changes from 90° to 120°.

[0020] With the above technical solution, along the direction away from the traveling mechanism, the angle between the second side and the third side is designed to gradually change from 90° to 120°, so that the gradual change trend of the third edge along the direction away from the traveling mechanism is relatively gentle, thereby realizing a gradual increase in the angle between the lifted second sealing portion and the first sealing portion.

[0021] In some embodiments of the present application, the traveling mechanism includes a mounting member, a first traveling component, and a second traveling component. The mounting member has a first side for facing the sealing edge. The first traveling component and the second traveling component are respectively connected to the first side and are arranged opposite to each other along a first direction. The first direction intersects the arrangement direction from the traveling mechanism to the peeling member. The first traveling component and the second traveling component are used to clamp the sealing edge and travel along the extending direction of the sealing edge.

[0022] With the above technical solution, the traveling mechanism is designed to include a mounting member, a first traveling component, and a second traveling component. The assembly of the first traveling component and the second traveling component is facilitated through the mounting member, and the peeling operation of the peeling member is realized by clamping the sealing edge with the first traveling component and the second traveling component and traveling along the extending direction of the sealing edge.

[0023] In some embodiments of the present application, the first traveling component and the second traveling component are configured to have an adjustable spacing along the first direction.

[0024] With the above technical solution, the first traveling component and the second traveling component are designed to have an adjustable spacing along the first direction, which not only facilitates clamping of the sealing edge by the two, but also enables the traveling mechanism to adapt to sealing edges of different thicknesses, improving its universality.

[0025] In some embodiments of the present application, the traveling mechanism further includes a distance adjustment component. The distance adjustment component is connected to the mounting member, and the first traveling component is connected to the distance adjustment component. The distance adjustment component is configured to drive the first traveling component to approach or move away from the second traveling component along the first direction.

[0026] With the above technical solution, by using the distance adjustment component to drive the first traveling component to approach or move away from the second traveling component along the first direction, only the movement of the first traveling component is required to adjust the distance between the first traveling component and the second traveling component along the first direction, simplifying the structure and the adjustment operation steps.

[0027] In some embodiments of the present application, the seal edge stripping device further includes a connecting member. One end of the opposite ends of the connecting member is connected to the traveling mechanism, and the other end is connected to the stripping member.

[0028] With the above technical solution, the seal edge stripping device is designed to further include a connecting member, which can facilitate the connection between the stripping member and the traveling mechanism and also meet the requirement of arranging the stripping member opposite to the traveling mechanism along the first direction.

[0029] In some embodiments of the present application, the traveling mechanism includes a first side facing the seal edge and a second side facing away from the seal edge. The connecting member includes a first connecting portion and a second connecting portion. The first connecting portion extends along the direction from the first side to the second side. One end of the first connecting portion is connected to the traveling mechanism, and the other end is connected to one end of the second connecting portion. The second connecting portion extends along the arrangement direction from the traveling mechanism to the stripping member, and the other end of the second connecting portion is connected to the stripping member.

[0030] With the above technical solution, the connecting member is designed as the intersecting first connecting portion and second connecting portion, which facilitates the installation of the stripping member at a position closer to the joint, so that the stripping member can better align with the joint.

[0031] In a second aspect, an embodiment of the present application provides a battery production system, including the seal edge stripping device according to any one of the above technical solutions. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components.

[0052] In the embodiments of the present application, the same reference numerals denote the same components, and for the sake of brevity, in different embodiments, the detailed description of the same components is omitted. It should be understood that the thicknesses, lengths, widths, etc. of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width, etc. of the integrated device are only illustrative and should not constitute any limitation to the present application.

[0053] The term "a plurality of" as used in the present application refers to two or more (including two).

[0054] Next, the embodiments of the present application will be described in detail.

[0055] Currently, battery devices are more and more widely used. Power batteries are not only applied to energy storage power systems such as hydraulic power plants, thermal power plants, wind power plants, and solar power plants, but also widely used in electric transportation tools such as electric bicycles, electric motorcycles, and electric vehicles, as well as in multiple fields such as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand is also continuously increasing.

[0056] In the production process of battery devices, it is necessary to seal and connect the edges of the upper cover and the lower box body of the battery box through processes such as hemming. After sealing, it is necessary to detect the sealed part. When the detection is unqualified, it is necessary to rework and remove the sealed connection at the edges of the upper cover and the lower box body.

[0057] The related art usually uses a flat-tip screwdriver held by hand in combination with a pair of needle-nose pliers for peeling and rework. This method not only has low removal efficiency, but also the manual operation is uncontrollable and easily damages the sealed edge structure.

[0058] Therefore, how to improve the efficiency of peeling and rework of the sealed edges of the upper cover and the lower box body of the battery box and reduce the possibility of damaging the sealed edge structure is an important issue in battery production and processing.

[0059] In view of this, the present application provides a technical solution, which provides a sealed edge peeling device. This device clamps the sealed edge through a traveling mechanism and travels on the sealed edge to drive the peeling member to perform peeling operations to solve the above technical problems.

[0060] Next, the sealed edge peeling device 100 provided by the embodiments of the present application will be introduced. Figures 1-7

[0061] Figures 1-4 ​​As shown in the figure, an embodiment of the present application provides a sealing edge peeling device 100, including a traveling mechanism 10 and a peeling member 20. The traveling mechanism 10 is used to clamp the sealing edge 200 and travel along the extending direction of the sealing edge 200. The peeling member 20 is connected to the traveling mechanism 10 and is provided with an insertion portion 21 for inserting into the connection seam 230 of the sealing edge 200. The insertion portion 21 is configured to peel the sealing edge 200 under the driving of the traveling of the traveling mechanism 10.

[0062] When peeling the sealing edge 200, the traveling mechanism 10 is mainly used to clamp and install on the sealing edge 200, and can travel along the extending direction or the length direction of the sealing edge 200 on the sealing edge 200. The traveling mode can be traveling by its own driving force or by an external driving force.

[0063] The peeling member 20 can be made of a rigid material such as metal. The peeling member 20 can be directly connected or indirectly connected to the traveling mechanism 10. The distance and position between the peeling member 20 and the traveling mechanism 10 can be determined according to the structural form of different sealing edges 200.

[0064] For example Figure 4 the sealing edge 200 therein includes a first sealing portion 210 and a second sealing portion 210. The first sealing portion 210 is one of the upper edge of the lower box body of the battery box and the lower edge of the upper cover of the battery box, and the second sealing portion 220 is the other of the upper edge of the lower box body of the battery box and the lower edge of the upper cover of the battery box.

[0065] The sealing edge 200 includes a first sealing portion 210 and a second sealing portion 220. In some embodiments, the first sealing portion 210 is a strip-shaped plate member, the thickness direction of which is arranged along the first direction X in the figure, and the length direction is arranged along the third direction Z in the figure (the arrangement direction from the peeling member 20 to the traveling mechanism 10). The second sealing portion 220 is a structure that wraps both sides of the first sealing portion 210 along the first direction X and has an approximately U-shaped cross-section.

[0066] When rework of peeling is required, the traveling mechanism 10 is installed on both sides of the second sealing portion 220 along the first direction X, and the traveling mechanism 10 is made to clamp the second sealing portion 220. At the same time, the peeling member 20 is aligned with one end of the connection seam 230 on the upper side of the first sealing portion 210 and the second sealing portion 220. As the traveling mechanism 10 drives the peeling member 20 to travel, the peeling member 20 gradually lifts the second sealing portion 220, thereby completing the release of the connection between the first sealing portion 210 and the second sealing portion 220.

[0067] Through the above peeling step, not only can the peeling operation of the continuous linear sealing joint be realized, which can effectively improve the glass efficiency, but also compared with the method of manually holding tools, the moving directions of the peeling member 20 and the traveling mechanism 10 are set along the extending direction of the sealing edge 200, and the accuracy of the peeling action is higher. Therefore, the damage to the structure of the sealing edge 200 can be reduced.

[0068] In some examples, optionally, the traveling mechanism 10 includes a first side 111 facing the sealing edge 200 and a second side 112 facing away from the sealing edge 200. Along the arrangement direction of the traveling mechanism 10 to the peeling member 20, the insertion portion 21 is arranged facing the traveling mechanism 10 and has a gap with the traveling mechanism 10. Along the direction away from the traveling mechanism 10, the dimension of the insertion portion 21 in the first direction X gradually increases. The first direction X intersects the arrangement direction of the traveling mechanism 10 to the peeling member 20 and intersects the arrangement direction of the first side 111 to the second side 112.

[0069] The traveling mechanism 10 includes a first side 111 facing the sealing edge 200. It should be noted that the first side 111 of this embodiment refers to the side facing one side in the width direction of the sealing edge 200 (the second direction Y in the figure), rather than the side facing one side in the width direction of the sealing edge 200.

[0070] Similarly, the second side 112 refers to the side facing away from one side in the width direction of the sealing edge 200 (the second direction Y in the figure).

[0071] Under the premise of such a sealing edge 200, it is necessary to make the peeling member 20 face the traveling mechanism 10 and form a certain gap with the traveling mechanism 10 along the third direction Z. The existence of this gap is designed to prevent the peeling member 20 from being affected by the clamping force of the traveling mechanism 10 when lifting the second sealing portion 220.

[0072] The peeling member 20 can be connected to the traveling mechanism 10 through its own configured connection structure to form the above gap, or it can also form the gap through the following connecting member 30.

[0073] Along the direction away from the traveling mechanism 10, the dimension of the insertion portion 21 in the first direction X gradually increases, and it is necessary to keep the second surface 212 on the lower side of the insertion portion 21 always parallel to the upper side surface of the first sealing portion 210, so that the second surface 212 of the insertion portion 21 can always be in contact with the upper side surface of the first sealing portion 210.

[0074] In this structure, the shape of the insertion part 21 is similar to a wedge or a right-angled triangle in cross-section. During the process of the walking mechanism 10 walking, the insertion part 21 can gradually increase the angle between the part of the second sealing part 220 that is lifted and the second sealing part 220, which not only facilitates the disconnection of the first sealing part 210 and the second sealing part 220, but also reduces the possibility of damaging the first sealing part 210 and the second sealing part 220.

[0075] Combined with the attached Figure 4 and 5 As shown, in some examples, optionally, the insertion part 21 includes a first surface 211 and a second surface 212 arranged oppositely along the first direction X. The sealing edge 200 includes a first sealing part 210 and a second sealing part that wraps at least part of the first sealing part 210. The first surface 211 is used to abut against the second sealing part 220, and the second surface 212 is used to abut against the first sealing part 210. One end of the first surface 211 facing the walking mechanism 10 and one end of the second surface 212 facing the walking mechanism 10 are connected to form a tip 213. Along the direction away from the walking mechanism 10, the distance between the first surface 211 and the second surface 212 along the first direction X gradually increases.

[0076] The first surface 211 is the upper surface of the insertion part 21 in the figure, and the second surface 212 is the lower surface of the insertion part 21 in the figure. In some embodiments, the first direction X can be understood as the thickness direction of the insertion part 21. When the insertion part 21 is inserted into the connection seam 230, the first surface 211 abuts against the lower surface of the second sealing part 220, and the second surface 212 abuts against the upper surface of the first sealing part 210. As the insertion part 21 walks along the third direction Z in the figure, and also because the thickness of the insertion part 21 gradually increases, the upper side edge of the second sealing part 220 and the first sealing part 210 change from being originally parallel to forming a certain angle.

[0077] One end of the first surface 211 facing the walking mechanism 10 and one end of the second surface 212 facing the walking mechanism 10 are connected to form a tip 213. The tip 213 can be in the shape of a flat nozzle or approximately beak-shaped, as long as its size can be inserted into the connection seam 230.

[0078] Designing one end of the insertion part 21 facing the walking mechanism 10 as the tip 213, so that the insertion part 21 can be inserted into the connection seam 230 conveniently, not only facilitates the insertion part 21 to lift the second sealing part 220 that wraps the first sealing part 210, but also can reduce the possibility of abrasion with the first sealing part 210 and the second sealing part 220 to a certain extent.

[0079] Combined with the attached again Figure 4 and 5As shown, in some examples, optionally, the walking mechanism 10 includes a first side 111 facing the sealing edge 200 and a second side 112 facing away from the sealing edge 200. The first surface 211 has a first edge 2111 and a second edge 2112 arranged oppositely along the second direction Y. The second direction Y is the arrangement direction from the first side 111 to the second side 112. The first edge 2111, the second edge 2112, and the second side 112 are arranged in sequence along the second direction Y. From the first edge 2111 to the second edge 2112, the distance between the first surface 211 and the second surface 212 along the first direction X gradually decreases.

[0080] Explanations have been given above regarding the first side 111 and the second side 112, and thus will not be elaborated in this embodiment.

[0081] The insertion portion 21 includes a first surface 211 and a second surface 212 arranged oppositely along the first direction X, and also includes a seventh surface and an eighth surface 214 arranged oppositely along the second direction Y. Among them, the first surface 211 and the seventh surface (not shown in the figure) intersect to form the above-mentioned first edge 2111, and the second surface 212 and the eighth surface 214 intersect to form the above-mentioned second edge 2112.

[0082] From the first edge 2111 to the second edge 2112, in this embodiment, the distance between the first surface 211 and the second surface 212 along the first direction X gradually decreases, so that the thickness of the insertion portion 21 closer to the inside of the connection seam 230 becomes smaller, and thus the first surface 211 of this embodiment forms a guiding surface for guiding the deformation direction of the second sealing portion 220.

[0083] Specifically, during the movement of the peeling member 20, the first surface 211 is in guiding cooperation with the second sealing portion 220. The angle between the portion of the second sealing portion 220 lifted by the peeling member 20 and the first sealing portion 210 gradually increases, and it can gradually move away from the first sealing portion 210 along the guidance of the first sealing portion 210, which is more convenient for the second sealing portion 220 to disengage from the first sealing portion 210, and also reduces the possibility of excessive deformation of the second sealing portion 220 due to too large a lifting angle and force.

[0084] In some embodiments, the first surface 211 is a curved surface recessed towards the second surface 212, and the curved surface can provide a better guiding effect and can guide the second sealing portion 220 to gradually move away from the first sealing portion 210.

[0085] Combined with the attached Figure 5As shown, in some examples, optionally, the traveling mechanism 10 includes a first side 111 facing the sealing edge 200 and a second side 112 facing away from the sealing edge 200. The peeling member 20 further includes a spreading portion 22. The spreading portion 22 is connected to one end of the insertion portion 21 away from the traveling mechanism 10. Along the second direction Y, the minimum dimension of the spreading portion 22 is greater than the maximum dimension of the insertion portion 21. The second direction Y is the arrangement direction from the first side 111 to the second side 112.

[0086] In some embodiments, the second direction Y is the width direction of the peeling member 20. The fact that the minimum dimension of the spreading portion 22 along the second direction Y is greater than the maximum dimension of the insertion portion 21 means that the width of the spreading portion 22 is greater than the width of the insertion portion 21, so that during the traveling of the peeling member 20, the spreading portion 22 can give a driving force to the second sealing portion 220 along the second direction Y, making it more convenient to peel the second sealing portion 220.

[0087] In some embodiments, the spreading portion 22 has a side facing away from the second side 112 and a side close to the second side 112. It may be that only the side close to the second side 112 along the second direction Y plays a spreading role, and the rest of the spreading portion 22 may not play a spreading role.

[0088] When the insertion portion 21 spreads the second sealing portion 220 by the spreading portion 22, as the peeling member 20 travels, the side of the spreading portion 22 close to the second side 112 is in guiding cooperation with the lifted second sealing portion 220, and the second sealing portion 220 is further lifted along the second direction Y, so that the second sealing portion 220 can be further separated from the first sealing portion 210.

[0089] Again referring to the attached Figure 5 As shown, in some examples, optionally, the spreading portion 22 includes a third surface 221 and a fourth surface 222 arranged oppositely along the first direction X, and a fifth surface 223 and a sixth surface 224 arranged oppositely along the second direction Y. The third surface 221 is connected to the first surface 211, the fourth surface 222 is connected to the second surface 212. The fifth surface 223, the sixth surface 224 and the second side 112 are arranged in sequence along the second direction Y. The sixth surface 224 intersects with the third surface 221 to form a third edge 225. The cross-section of the spreading portion 22 parallel to the first direction X and the second direction Y includes a first side edge, a second side edge and a third side edge connected at an angle in sequence. The first side edge is located on the third surface 221, the second side edge is located on the sixth surface 224, and the third side edge is located on the fourth surface 222. From the end of the spreading portion 22 facing the traveling mechanism 10 to the end facing away from the traveling mechanism 10, the included angle between the first side edge and the second side edge gradually decreases, and the included angle between the second side edge and the third side edge gradually increases.

[0090] In some embodiments, the third surface 221 and the fourth surface 222 are two surfaces of the spreading portion 22 in the thickness direction, and the fifth surface 223 and the sixth surface 224 are two surfaces of the spreading portion 22 in the width direction.

[0091] The third surface 221 and the first surface 211 can be angularly connected or connected with an arc transition. The third surface 221 is higher than the first surface 211. The edge of the third surface 221 close to the second side 112 is used to spread the second sealing portion 220, and the second surface 212 can also be used to connect one end of the following connecting member 30 away from the traveling mechanism 10.

[0092] The fourth surface 222 and the second surface 212 can be angularly connected or connected with an arc transition. In some embodiments, the fourth surface 222 can also be flush with the second surface 212 to form a surface structure.

[0093] The sixth surface 224 is angularly connected to the third surface 221 and the two form a third edge 225. The third edge 225 is used to spread the second sealing portion 220. The sixth surface 224 is angularly connected to the fourth surface 222 and the two form a fourth edge 226.

[0094] In order to enable the third edge 225 to gradually increase the angle between the second sealing portion 220 and the first sealing portion 210 after being lifted, the structure of the spreading portion 22 is optimized in this embodiment. From the end of the spreading portion 22 facing the traveling mechanism 10 to the end away from the traveling mechanism 10, the included angle between the first side 111 edge and the second side edge of the cross-section of the spreading portion 22 is gradually reduced, and the included angle between the second side edge and the third side edge is gradually increased.

[0095] Taking Figure 5 the cross-section of the spreading portion 22 near the traveling mechanism 10 as an example, the extension direction of the first side 111 edge of this cross-section is marked as a1, the extension direction of the second side edge is marked as a2, the extension direction of the third side edge is marked as a3, the included angle formed by a1 and a2 is α1, the included angle formed by a2 and a3 is β1, and β1 can be equal to α1. The above-mentioned side edge extension directions are shown by dotted lines.

[0096] For example, α1 and β1 can be 30° to 90°, such as 30°, 40°, 50°, 60° and 90°, etc. In some embodiments, α1 is 90° and β1 is also 90°.

[0097] The cross-sectional shape of the spreading portion 22 gradually changes along the direction away from the traveling mechanism 10, taking Figure 5Taking a cross-section at one end of the expansion part 22 facing away from the traveling mechanism 10 as an example, the extension direction of the first side 111 at this cross-section is marked as a4, the extension direction of the second side is marked as a5, and the extension direction of the third side is marked as a6. The angle formed by a4 and a5 is α2, and the angle formed by a5 and a6 is β2, and β2 is greater than α2. The above-mentioned side extension directions are shown by dotted lines.

[0098] In some embodiments, a2 is an acute angle and β2 is an obtuse angle. It can be seen that from the end of the expansion part 22 facing the traveling mechanism 10 to the end facing away from the traveling mechanism 10, the angle between the first side 111 and the second side gradually decreases, and in some embodiments, the angle between the first side 111 and the second side can change from a right angle to an acute angle.

[0099] Similarly, from the end of the expansion part 22 facing the traveling mechanism 10 to the end facing away from the traveling mechanism 10, the angle between the second side and the third side gradually increases. In some embodiments, the angle between the second side and the third side can change from a right angle to an obtuse angle.

[0100] This kind of structure can make the sixth surface 224 form a gradually changing curved surface structure, and make the distance between the third edge 225 and the second side 112 along the second direction Y gradually decrease in the direction away from the traveling mechanism 10. Furthermore, during the traveling process of the expansion part 22 following the traveling mechanism 10, the second sealing part 220 in contact with and lifted by the third edge 225 gradually moves away from the first sealing part 210 along the second direction Y, and gradually expands the angle between the lifted second sealing part 220 and the first sealing part 210. Moreover, it can also reduce the possibility of damage to the second sealing part 220, and the distance between the fourth edge 226 and the second side 112 along the second direction Y remains unchanged, which can reduce the possibility of contact between the fourth edge 226 and the lifted second sealing part 220, thereby reducing the resistance during the traveling process of the expansion part 22.

[0101] In some examples, optionally, the third edge 225 is an arc transition structure.

[0102] Arc transition means that the cross-section of this edge is approximately arc-shaped or curved. Arc transition is mainly used to smoothly connect two different planes or curved surfaces (such as connecting the third surface 221 and the sixth surface 224).

[0103] In this embodiment, the third edge 225 is designed as an arc transition structure, which can make the third edge 225 better guide the second sealing part 220 to deform along the preset direction and reduce the possibility of scratching the second sealing part 220 after contact between the third edge 225 and the second sealing part 220.

[0104] Similarly, the fourth edge 226 can also be designed as an arc transition structure, so that the fourth edge 226 can play a guiding role once it contacts the side of the opened second sealing part 220 close to the first sealing part 210, and can also reduce the possibility of the fourth edge 226 scratching the second sealing part 220 after contacting the second sealing part 220.

[0105] In some examples, optionally, from one end of the support portion 22 facing the walking mechanism 10 to the other end facing away from the walking mechanism 10 , the angle between the second side and the third side gradually changes from 90° to 120°.

[0106] That is, the included angle between the second side and the third side changes from the aforementioned β1 to β2, β1 is 90°, and β2 is 120°.

[0107] This structural design allows the third edge 225 to have a slower gradual change in the direction away from the running mechanism 10 , thereby gradually increasing the angle between the second sealing portion 220 and the first sealing portion 210 after being opened.

[0108] Combined with attachment Figure 1 and attached Figure 7 As shown, in some examples, optionally, the walking mechanism 10 includes a mounting member 11, a first walking component 12 and a second walking component 13, the mounting member 11 has a first side 111 for facing the sealing edge 200, the first walking component 12 and the second walking component 13 are respectively connected to the first side 111 and the two are arranged opposite to each other along a first direction X, the first direction X intersects with the arrangement direction of the walking mechanism 10 to the peeling member 20, the first walking component 12 and the second walking component 13 are used to clamp the sealing edge 200 and walk along the extension direction of the sealing edge 200.

[0109] The mounting member 11 is provided with the aforementioned first side 111 and second side 112. The mounting member 11 may include a mounting plate structure, but may also include any mounting structure such as a mounting frame or a mounting block, as long as it can meet the requirements for the installation of the first and second traveling assemblies 12 and 13. This embodiment does not impose any further restrictions on this.

[0110] The first and second travel assemblies 12, 13 may have the same or different structures. For example, the first travel assembly 12 may include a motor (not shown) and a first travel wheel 121, and the second travel assembly 13 may also include a motor and a second travel wheel 131 (not shown). Alternatively, the first travel assembly 12 may include the first travel wheel 121 with its own battery, and the second travel assembly 13 may include the second travel wheel 131 with its own battery.

[0111] Taking the first walking assembly 12 as an example, the number of the first walking wheels 121 of the first walking assembly 12 can be one or more. When the number of the first walking wheels 121 is more than one, a plurality of first walking wheels 121 can also be connected by a transmission belt, so that the synchronous rotation of a plurality of first walking wheels 121 can be realized by driving the rotation of one first walking wheel 121. The same applies to the second walking assembly 13 in this embodiment, and thus will not be elaborated herein.

[0112] In addition, the first walking wheel 121 and the second walking wheel 131 can also be drivingly connected by structures such as a synchronous belt (not shown in the figure), and the rotation of the first walking wheel 121 and the second walking wheel 131 can be driven by using one drive.

[0113] In this embodiment, the walking mechanism 10 is designed to include a mounting member 11, a first walking assembly 12 and a second walking assembly 13. The mounting member 11 facilitates the assembly of the first walking assembly 12 and the second walking assembly 13, and the first walking assembly 12 and the second walking assembly 13 clamp the sealing edge 200 and walk along the extending direction of the sealing edge 200 to realize the peeling operation of the peeling member 20.

[0114] In some examples, optionally, the first walking assembly 12 and the second walking assembly 13 are configured to have an adjustable spacing along the first direction X.

[0115] Designing the first walking assembly 12 and the second walking assembly 13 to have an adjustable spacing along the first direction X not only facilitates clamping the sealing edge 200 by the two, but also enables the walking mechanism 10 to adapt to sealing edges 200 of different thicknesses, thereby improving its universality.

[0116] The adjustable spacing of the first walking assembly 12 and the second walking assembly 13 along the first direction X means that at least one of the first walking assembly 12 and the second walking assembly 13 can move its position along the first direction X and can maintain the stability after moving the position.

[0117] There are various implementation manners for the adjustable spacing of the first walking assembly 12 and the second walking assembly 13 along the first direction X. Taking that the first walking assembly 12 can move its position along the first direction X as an example, the first walking assembly 12 can be integrally mounted on an adapter (not shown in the figure), and the adapter is connected to the mounting member 11 in a manner that the position can be adjusted along the first direction X.

[0118] For example, the mounting member 11 is provided with a plurality of connection holes at intervals along the first direction X (such an embodiment is not shown in the figure). The adapter can select to dock with one of the connection holes through a connecting member 30 such as a bolt, so as to realize the adjustment of the position of the adapter and the first traveling assembly 12. It is also possible that the rotating shaft of the first traveling wheel 121 is directly installed in one of the connection holes to realize the adjustment of the position of the first traveling wheel 121.

[0119] In addition to the form of the adapter, the first traveling assembly 12 can also be installed through the following distance adjustment assembly 14. The distance adjustment assembly 14 drives the first traveling assembly 12 to move along the first direction X, so as to realize the adjustment of the position of the first traveling assembly 12 along the first direction X.

[0120] Similarly, the adjustment of the position of the second traveling assembly 13 along the first direction X is the same as or similar to that of the first traveling assembly 12 above, and this embodiment will not describe it in detail.

[0121] In some examples, optionally, the traveling mechanism 10 further includes a distance adjustment assembly 14. The distance adjustment assembly 14 is connected to the mounting member 11, and the first traveling assembly 12 is connected to the distance adjustment assembly 14. The distance adjustment assembly 14 is used to drive the first traveling assembly 12 to approach or move away from the second traveling assembly 13 along the first direction X.

[0122] The distance adjustment assembly 14 can be any structure capable of performing linear reciprocating motion. For example, the distance adjustment assembly 14 in the figure includes a distance adjustment bolt 141. The distance adjustment bolt 141 is threadedly connected to the mounting member 11, and a part of the distance adjustment bolt 141 is located outside the mounting member 11 and is used to connect the wheel carrier 122 of the first traveling wheel 121. The first traveling wheel 121 can rotate on the wheel carrier 122. By screwing the distance adjustment bolt 141, the wheel carrier 122 and the first traveling wheel 121 can be driven to move along the first direction X.

[0123] Of course, in addition to the distance adjustment bolt 141, the distance adjustment assembly 14 can also include a linear reciprocating motion structure, such as a pneumatic rod, an electric rod or a hydraulic rod, etc., and this embodiment will not list them one by one.

[0124] In this embodiment, the distance adjustment assembly 14 is used to drive the first traveling assembly 12 to approach or move away from the second traveling assembly 13 along the first direction X. Only by moving the first traveling assembly 12 can the adjustment of the distance between the first traveling assembly 12 and the second traveling assembly 13 along the first direction X be realized, which simplifies the structure and the adjustment operation steps.

[0125] Combined with the attached Figure 1 and the attached Figure 6 As shown, in some examples, optionally, the sealing edge peeling device 100 further includes a connecting member 30. One end of the opposite ends of the connecting member 30 is connected to the traveling mechanism 10, and the other end is connected to the peeling member 20.

[0126] The purpose of configuring the connecting member 30 is not only to facilitate the connection between the peeling member 20 and the traveling mechanism 10, but also to meet the requirement of setting the peeling member 20 opposite to the traveling mechanism 10 along the first direction X, so that when the peeling member 20 lifts the second sealing portion 220, the traveling mechanism 10 will not generate a clamping force on this part of the second sealing portion 220.

[0127] The connecting member 30 can be a rod-shaped member, a plate-shaped member, a block-shaped member, etc. The connection method between the connecting member 30 and the peeling member 20 is not limited, as long as the relative stability after the connection of the two is satisfied. For example, the connecting member 30 and the peeling member 20 can be mechanically connected by snap connection, plug connection, welding, bolt connection, etc. The connection method between the connecting member 30 and the traveling mechanism 10 can also be the same.

[0128] In some examples, optionally, the traveling mechanism 10 includes a first side 111 facing the sealing edge 200 and a second side 112 facing away from the sealing edge 200. The connecting member 30 includes a first connecting portion 31 and a second connecting portion 32. The first connecting portion 31 extends along the direction from the first side 111 to the second side 112. One end of the first connecting portion 31 is connected to the traveling mechanism 10, and the other end is connected to one end of the second connecting portion 32. The second connecting portion 32 extends along the arrangement direction from the traveling mechanism 10 to the peeling member 20, and the other end of the second connecting portion 32 is connected to the peeling member 20.

[0129] In this embodiment, the connecting member 30 is designed to include a first connecting portion 31 and a second connecting portion 32. The length of the first connecting portion 31 extends along the second direction Y in the figure, and the length of the second connecting portion 32 extends along the third direction Z in the figure.

[0130] One end of the first connecting portion 31 is fixedly connected to the connecting member 30 of the traveling mechanism 10, and the other end is connected to the second connecting portion 32. One end of the second connecting portion 32 is fixedly connected to the first connecting portion 31, and the other end is fixedly connected to the peeling member 20. The connection method can be any of the above fixed mechanical connection methods.

[0131] In some embodiments, the first connecting portion 31 and the second connecting portion 32 can be integrally connected by welding, heat fusion connection, etc., or can also be integrally formed during processing.

[0132] The first direction X, the second direction Y, and the third direction Z intersect pairwise. In some embodiments, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other pairwise. At this time, the first connecting portion 31 and the second connecting portion 32 are perpendicular to each other.

[0133] The connecting member 30 is designed as an intersecting first connecting portion 31 and second connecting portion 32, facilitating the installation of the peeling member 20 at a position closer to the connection seam 230, so that the peeling member 20 can better align with the connection seam 230.

[0134] To increase the distance between the traveling mechanism 10 and the peeling member 20 in the third direction Z, the mounting member 11 can also be designed to include an extension portion 113. The extension portion 113 can be a plate-like member as shown in the figure. One end of the first connecting portion 31 is connected to one end of the extension portion 113, and the other end of the extension portion 113 is connected to the mounting member 11. The connection method is a mechanical connection method such as welding or snap connection.

[0135] Of course, in some embodiments, the extension portion 113 can also be regarded as a part of the connecting member 30.

[0136] The above description is only an overview of the technical solution of the present application.
