Description

Technical Field

[0001] The present application relates to the technical field of molds, and in particular to a positioning tool. Background Art

[0002] At present, the metal top cover and plastic bracket in some battery top covers are connected by ultrasonic hot melting. However, the existing positioning tooling has a problem of being placed offset when the metal top cover is placed. This will cause the metal top cover and the positioning tooling to scrape against each other to form metal wires, increasing the probability of defects or poor quality in the finished battery top cover. Utility Model Content

[0003] The present application provides a positioning tool, which aims to solve the problem that the top cover sheet in the battery top cover is scratched by the positioning tool due to deviation, resulting in a reduced yield of the finished battery top cover.

[0004] In order to solve the above problems, the present application provides, on the one hand, a positioning tool for placing the product to be hot-melted, characterized in that the positioning tool includes: a fixing component and a guide component; the fixing component has a placement surface for placing the product to be hot-melted, the guide component is arranged on the fixing component, and at least one guide component is provided in the area where each edge of the placement surface is located; when the product to be hot-melted is placed off-center, the guide component is configured to guide the product to be hot-melted to the placement surface.

[0005] In the above scheme, since the placement surface of the fixed component can be used for placing the product to be hot-melted, and the area where each edge of the placement surface is located is provided with at least one guide component, and the guide component can guide the product to be hot-melted when the product to be hot-melted is deviated, and guide the product to be hot-melted to the placement surface, the guide component can be used to reduce the probability of the product to be hot-melted scratching the fixed component due to deviation, thereby improving the finished product yield of the product to be hot-melted.

[0006] In one embodiment, the guide assembly can generate rolling friction with the deviated product to be hot-melt and guide the product to be hot-melt to the placement surface.

[0007] Therefore, the rolling friction between the guide assembly and the product to be hot-melted can be utilized to reduce the probability of the product to be hot-melted being scratched by the guide assembly.

[0008] In one embodiment, the guide assembly includes: a connecting member and a rolling member; the connecting member is provided on the fixed assembly, the rolling member is rotatably provided on the connecting member, and the rolling member can generate rolling friction with the deviated product to be hot-melt and guide the product to be hot-melt to the placement surface.

[0009] Thus, by providing a rolling element on the connecting member that can generate rolling friction with the product to be hot-melted, the rolling element allows the product to change its displacement direction when it is placed off-center, allowing it to be placed on the placement surface under the guidance of the rolling element, thereby reducing the probability of the product to be hot-melted scraping against the fixed component due to off-center placement. Furthermore, by guiding the product with the rolling element, friction between the product to be hot-melted and the rolling element is reduced, thereby reducing the probability of the product being scratched by the rolling element.

[0010] In one embodiment, the fixing assembly includes: a fixing seat and a plurality of non-metallic blocks; the fixing seat has the placement surface, and the plurality of non-metallic blocks are arranged on the fixing seat at intervals and are arranged together around the placement surface to limit the displacement of the product to be hot-melt on the placement surface.

[0011] Therefore, by arranging multiple non-metallic blocks on the fixing seat and surrounding the placement surface, not only can the multiple non-metallic blocks be used to limit the displacement of the product to be hot-melted on the placement surface, but also the collision between the non-metallic blocks and the product to be hot-melted to generate metal chips can be avoided.

[0012] In one embodiment, the guide assembly includes: a connecting member and a rolling member; the connecting member is provided on the fixed seat and is located between two adjacent non-metallic blocks; the rolling member is rotatably provided on the connecting member and protrudes from the side of the non-metallic block away from the fixed seat; when the product to be hot-melt is deviated, the rolling member can generate rolling friction with the product to be hot-melt and guide the product to be hot-melt to the placement surface.

[0013] Therefore, by arranging the rolling member to protrude from the side of the non-metallic block away from the fixed seat, the deviated product to be hot-melted can contact the rolling member and be placed on the placement surface under the guidance of the rolling member, so as to reduce the probability of the product to be hot-melted scratching the non-metallic block due to deviation.

[0014] In one embodiment, the fixing assembly further includes: a limiting bracket; the limiting bracket is movably disposed on a side of the non-metallic block away from the fixing seat, and can contact the product to be hot-melt to limit the displacement of the product to be hot-melt in a direction parallel to the placement surface.

[0015] Therefore, by arranging a removable limiting bracket on the side of the non-metallic block away from the fixed seat, and the limiting bracket can contact the product to be hot-melted placed on the placement surface, and can limit the displacement of the product to be hot-melted in a direction parallel to the placement surface, the limiting bracket can first be moved away to avoid the placement of the product to be hot-melted, and then reset to limit the placed product to be hot-melted, so as to reduce the probability of position displacement of the product to be hot-melted during ultrasonic heat melting.

[0016] In one embodiment, the placement surface has an angle, and the limiting bracket can contact the product to be hot-melted at the angle and limit the displacement of the product to be hot-melted in the extension direction of the two sides of the placement surface forming the angle.

[0017] Therefore, by setting a limiting bracket to limit the hot-melt product at the angle of the placement surface, not only can the displacement of the hot-melt product in the direction parallel to the placement surface be effectively limited, but the guide component can also be avoided.

[0018] In one embodiment, the placement surface includes: two relatively long sides and two relatively short sides; the two long sides intersect with the two short sides to form four angles; the number of the limiting brackets is two, and the two limiting brackets are respectively located at the two short sides; the limiting brackets can contact the product to be hot-melt at the two angles adjacent to the short sides.

[0019] Therefore, by setting two limiting brackets at the two short sides of the placement surface respectively, and the limiting brackets can contact the product to be hot-melted at two angles adjacent to the short sides and limit the product to be hot-melted, the number of limiting brackets required can be reduced.

[0020] In one embodiment, a softening layer is provided on the placement surface, and the softening layer is located between the placement surface and the product to be hot-melt.

[0021] Therefore, by providing a softening layer on the placement surface, the softening layer can be utilized to contact the product to be hot-melted, thereby reducing the probability of the product to be hot-melted being scratched by friction with the fixing seat during the ultrasonic hot-melting process.

[0022] In one embodiment, the rolling element is a ball or a roller.

[0023] Therefore, the rolling friction between the rolling element and the product to be hot-melt can be achieved by using balls or rollers, so as to reduce the probability of the product to be hot-melt being scratched by the rolling element.

[0024] In one embodiment, the product to be hot-melted includes: a top cover sheet and a lower plastic; the top cover sheet is placed on the placement surface, and is guided by the guide assembly to be transferred to the placement surface when it is offset; a plurality of non-metallic blocks are configured to limit the top cover sheet on the placement surface; the lower plastic is placed on the side of the top cover sheet away from the placement surface, and is protruding from the side of the non-metallic block away from the fixing seat; the limiting bracket can contact the lower plastic to limit the displacement of the lower plastic in a direction parallel to the placement surface.

[0025] Thus, the guide assembly can be used to guide the top cover sheet that is placed off-center, thereby reducing the probability of the top cover sheet scraping against the fixing assembly due to the off-center placement. At the same time, the removable limit bracket can also be used to limit the position of the lower plastic, thereby reducing the probability of the lower plastic shifting during the ultrasonic heat melting process.

For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0044] In some solutions, the metal top cover and plastic bracket of the battery top cover are connected using ultrasonic hot melting. Before hot melting the metal top cover and the plastic bracket, they need to be placed on a positioning fixture for positioning to reduce the probability of the metal top cover and the plastic bracket shifting during hot melting. However, since the metal top cover is placed off-center when placed on the positioning fixture, and the off-center metal top cover easily scrapes against the positioning fixture to form metal wires, the probability of defects or poor quality in the finished battery top cover increases, resulting in a lower yield rate for the finished battery top cover.

[0045] In order to solve the above technical problems, the present application provides a positioning tool, which arranges a guide component on a fixed component for placing the product to be hot-melt, and each side of the placement surface of the fixed component for placing the product to be hot-melt is provided with at least one guide component, and the guide component can be used to guide the deviated product to be hot-melt to the placement surface, so that the positioning tool can use the guide component to correct the deviated product to be hot-melt, so as to reduce the probability of defects or defects in the product to be hot-melt due to scratching between the deviated product and the fixed component, thereby improving the finished product yield of the product to be hot-melt.

[0046] The following is a detailed description of the positioning tool provided by this application in conjunction with the accompanying drawings. Figures 1 to 2 , Figure 1 1 is a schematic structural diagram of a positioning tool 10 and a product to be hot-melted 20 provided in an embodiment of the present application. Figure 2 yes Figure 1 Schematic diagram of the structure of the positioning tool 10.

[0047] The positioning tool 10 provided in the embodiment of the present application can be used to place the product 20 to be hot-melted, and can position the product 20 to be hot-melted to limit the displacement of the product 20 to be hot-melted during the ultrasonic hot-melting process. Figures 1 to 2As shown, the positioning fixture 10 may include a fixing assembly 100 and a guide assembly 200. The fixing assembly 100 may have a placement surface 101 for placing the hot-melt product 20. The guide assembly 200 is disposed on the fixing assembly 100, with at least one guide assembly 200 disposed along each side of the placement surface 101. If the hot-melt product 20 is misaligned, the guide assembly 200 can guide the hot-melt product 20 back onto the placement surface 101.

[0048] The fixing assembly 100 can use the placement surface 101 to carry the product 20 to be hot-melted and support the product 20 to be hot-melted during the hot-melting process. At the same time, the fixing assembly 100 can also limit the position of the product 20 to be hot-melted on the placement surface 101 to restrict the displacement of the product 20 to be hot-melted on the placement surface 101. For example, the fixing assembly 100 can be formed with a limiting space 102 located on the placement surface 101. When the product 20 to be hot-melted is placed on the placement surface 101, the product 20 to be hot-melted can be simultaneously limited within the limiting space 102. The limiting space 102 can be used to limit the position of the product 20 to be hot-melted, thereby reducing the probability of positional displacement of the product 20 to be hot-melted during the hot-melting process.

[0049] In some embodiments, the fixing assembly 100 can be connected to the processing table via a removable or non-removable method such as a snap connection, welding, or bolt connection. Furthermore, the fixing assembly 100 can be positioned on the processing table in a fixed or movable manner to facilitate adjustment of the position of the hot-melt product 20 on the processing table. For example, the fixing assembly 100 and the processing table can be slidably connected via a sliding structure such as a slide rail or a slide groove, allowing the fixing assembly 100 to move on the processing table.

[0050] The placement surface 101 can be the side of the fixing assembly 100 facing away from the processing table, and the shape of the placement surface 101 can match the shape of the product 20 to be hot-melted, such as a rectangle or a circle. Similarly, the size of the placement surface 101 can also match the size of the product 20 to be hot-melted, or be larger than the size of the product 20 to be hot-melted, so as to reserve space to accommodate the placement of the product 20. Considering that the surface of the product 20 to be hot-melted that contacts the placement surface 101 may also have some raised structures, the placement surface 101 can also have a clearance position for accommodating the product 20 to be hot-melted, such as a clearance groove or a clearance hole, to avoid the raised structures on the product 20 to be hot-melted, thereby improving the fit between the product 20 to be hot-melted and the placement surface 101.

[0051] In this embodiment, the reference direction X is a direction perpendicular to the placement surface 101, and the product 20 to be hot-melted can be placed on the placement surface 101 along the reference direction X. It should be understood that the reference direction X is merely an exemplary illustration of the placement direction of the product 20 to be hot-melted, and the actual placement direction of the product 20 to be hot-melted is not limited to the reference direction X. For example, during the actual placement process, the product 20 to be hot-melted can also be placed in a direction inclined at a certain angle to the reference direction X, as long as the product 20 to be hot-melted can be placed on the placement surface 101.

[0052] The orthographic projection of the guide assembly 200 on the fixing assembly 100 can be located outside the placement surface 101, so that the hot-melt product 20 does not contact the guide assembly 200 when placed properly, thereby reducing the probability of the hot-melt product 20 being scratched by the guide assembly 200 during normal placement. At the same time, the edge of the orthographic projection of the guide assembly 200 on the fixing assembly 100 can be close to or in contact with the edge of the placement surface 101, thereby reducing the probability of the hot-melt product 20 being placed off-center after being guided by the guide assembly 200. Here, the hot-melt product 20 being off-center can refer to the fact that part of its orthographic projection on the fixing assembly 100 is located outside the placement surface 101 when the hot-melt product 20 is placed, while the hot-melt product 20 being placed properly can refer to the fact that the entire orthographic projection of the hot-melt product 20 on the fixing assembly 100 is located within the placement surface 101 when the hot-melt product 20 is placed.

[0053] In the above scheme, since the placement surface 101 of the fixing component 100 can be used to place the product to be hot-melted 20, and each edge of the placement surface 101 is located in an area with at least one guide component 200, and the guide component 200 can guide the deviated product to be hot-melted 20 and guide the product to be hot-melted 20 to the placement surface 101, the guide component 200 can be used to reduce the probability of the product to be hot-melted 20 scratching the fixing component 100 due to deviation, thereby improving the finished product yield of the product to be hot-melted 20.

[0054] It can be understood that the orthographic projections referred to in the embodiments of the present application are all formed by irradiating light along the reference direction X. For the sake of convenience, this will not be described in detail below.

[0055] See also Figures 3 and 4 , Figure 3 yes Figure 1 Schematic diagram of the partial cross-sectional structure of the positioning tool 10 and the product to be hot-melted 20 along V-V, Figure 4 yes Figure 2 Schematic diagram of the connection structure between the middle fixing seat 110 and the non-metallic block 120.

[0056] In order to carry and position the product 20 to be hot-melted, the fixing assembly 100 may include: a fixing seat 110 and a plurality of non-metallic blocks 120. Figures 3 and 4As shown, the fixing seat 110 has a placement surface 101 , and a plurality of non-metallic blocks 120 are arranged at intervals on the fixing seat 110 and are arranged together around the placement surface 101 to limit the displacement of the product 20 to be hot-melted on the placement surface 101 .

[0057] The fixing seat 110 can be detachably or non-detachably arranged on the processing table, and the placement surface 101 can be a side of the fixing seat 110 facing away from the processing table. In order to reduce the probability of the non-metallic block 120 occupying the placement surface 101 during installation, the portion of the surface of the fixing seat 110 arranged around the placement surface 101 can be recessed to form an annular groove 111 arranged around the placement surface 101, and multiple non-metallic blocks 120 can be arranged at intervals in the annular groove 111 and together surround the placement surface 101. Of course, in some embodiments, the design of the annular groove 111 can also be omitted, and multiple non-metallic blocks 120 can also be arranged at intervals on the portion of the surface of the fixing seat 110 surrounding the placement surface 101, and it is only necessary that multiple non-metallic blocks 120 can be arranged together around the placement surface 101.

[0058] The plurality of non-metallic blocks 120 can be arranged at intervals within the annular groove 111 and can be disposed together around the placement surface 101. The plurality of non-metallic blocks 120 can also define the aforementioned limiting space 102 on the placement surface 101 to limit the displacement of the hot-melt product 20 on the placement surface 101. In other words, the height of the non-metallic blocks 120 can be greater than the depth of the annular groove 111, so that the plurality of non-metallic blocks 120 can protrude from the annular groove 111, thereby defining the limiting space 102 on the placement surface 101 to limit the position of the hot-melt product 20.

[0059] The edge of the orthographic projection of the non-metallic block 120 on the fixing seat 110 can be close to the edge of the placement surface 101, so that the non-metallic block 120 can limit the displacement of the product 20 to be hot-melted on the placement surface 101. During ultrasonic hot melting, the product 20 to be hot-melted will vibrate and displace in a direction parallel to the placement surface 101. The non-metallic block 120 can be used to limit the displacement of the product 20 to be hot-melted, thereby reducing the probability of structural components in the product 20 to be hot-melted being misaligned after hot melting. This does not mean that the non-metallic block 120 completely blocks or blocks the displacement of the product 20 to be hot-melted.

[0060] To position the hot-melt product 20, the non-metallic block 120 may have a Shore hardness greater than or equal to 80. This ensures that the non-metallic block 120 has sufficient strength and toughness to withstand the impact of the hot-melt product 20 during ultrasonic hot-melting, while also preventing collisions with the hot-melt product 20 and generating metal chips. For example, the non-metallic block 120 may be made of plastic or rubber with a Shore hardness between 80 and 90, such as sintered steel or nitrile rubber. Of course, in addition to plastic and rubber, the non-metallic block 120 may also be made of other non-metallic wear-resistant materials with a Shore hardness between 80 and 90, which are not specifically listed in this embodiment.

[0061] In the above solution, by providing a plurality of non-metallic blocks 120 on the fixing base 110 and surrounding the placement surface 101, the plurality of non-metallic blocks 120 can not only limit the displacement of the hot-melt product 20 on the placement surface 101, but also prevent the non-metallic blocks 120 from colliding with the hot-melt product 20 and generating metal chips. Furthermore, providing a plurality of non-metallic blocks 120 surrounding the placement surface 101 to limit the position of the hot-melt product 20 not only increases the layout flexibility of the non-metallic blocks 120, but also allows for targeted replacement of non-metallic blocks 120 that are subject to significant wear, thereby reducing subsequent maintenance costs.

[0062] In some embodiments, the plurality of non-metallic blocks 120 may be connected to form a single body, rather than being separated into multiple pieces. Specifically, the plurality of non-metallic blocks 120 may be connected to form an annular structure that matches the annular groove 111 , and the annular structure may define a limiting space 102 on the placement surface 101 to limit the displacement of the hot-melt product 20 on the placement surface 101 .

[0063] In some embodiments, as Figure 3 As shown, a softening layer 130 may also be provided on the placement surface 101 , and the softening layer 130 may be located between the placement surface 101 and the product 20 to be hot-melted.

[0064] The softening layer 130 can be attached to the placement surface 101, and the shape and size of the softening layer 130 can match the placement surface 101. The softening layer 130 can be made of Teflon, and can be used to separate the hot-melt product 20 from the placement surface 101 and provide a softening effect. Furthermore, the number of softening layers 130 can be two or fewer, specifically one, to reduce the thickness of the softening layer 130 and thereby minimize its impact on ultrasonic heat fusion of the hot-melt product 20. In some embodiments, the softening layer 130 can be made of other high-temperature adhesives besides Teflon.

[0065] In the above scheme, by setting a softening layer 130 on the placement surface 101, the softening layer 130 can be used to separate the fixing seat 110 and the product to be hot-melted 20, so as to reduce the probability of the product to be hot-melted 20 being scratched by friction with the fixing seat 110 during the ultrasonic hot melting process, that is, during vibration.

[0066] See also Figures 5 to 7 , Figure 5 yes Figure 2 Schematic diagram of the connection structure of the middle fixing seat 110, the non-metallic block 120 and the guide assembly 200, Figure 6 yes Figure 5 A schematic diagram of a partial cross-sectional structure of the middle fixing seat 310, the non-metallic block 120 and the guide assembly 200 along V-V. Figure 7 1 is a schematic diagram of a partial connection structure of the fixing base 110, the non-metallic block 120 and the connecting member 210 in some embodiments.

[0067] like Figure 5 and Figure 6 As shown, in order to guide the deviated product 20 to be hot-melted, the guide assembly 200 can generate rolling friction with the deviated product 20 to be hot-melted and guide the product 20 to be hot-melted onto the placement surface 101 .

[0068] The guide component 200 can specifically be a bearing, and when the product to be hot-melt 20 is deviated in the reference direction X, the product to be hot-melt 20 can contact the guide component 200 and generate rolling friction with the guide component 200, so that the product to be hot-melt 20 can change its own displacement direction under the action of the rolling friction of the guide component 200, so as to realize the guidance of the hot-melt product 20 by the guide component 200.

[0069] In the above scheme, by setting the rolling friction between the guide component 200 and the product to be hot-melt 20, not only can the guide component 200 be used to guide the product to be hot-melt 20, but also the friction generated by the guide component 200 and the product to be hot-melt 20 can be reduced, thereby reducing the probability of the product to be hot-melt 20 being scratched by the guide component 200.

[0070] In order to generate rolling friction with the deflected hot-melt product 20, the guide assembly 200 may include: a connecting member 210 and a rolling member 220. Figures 5 and 6 As shown, the connecting member 210 can be disposed on the fixing base 110 and positioned between two adjacent non-metallic blocks 120. The rolling member 220 can be rotatably disposed on the connecting member 210 and protrude from the side of the non-metallic block 120 facing away from the fixing base 110. When the hot-melt product 20 is placed off-center, the rolling member 220 can generate rolling friction with the hot-melt product 20 to guide the hot-melt product 20 onto the placement surface 101.

[0071] The connector 210 can be used to connect the fixed seat 110 and the rolling member 220 to mount the rolling member 220 on the fixed seat 110. The connector 210 can also be disposed within the annular groove 111 and between two adjacent non-metallic blocks 120. Furthermore, the connector 210 can protrude from the side of the non-metallic block 120 facing away from the fixed seat 110, that is, from the side of the non-metallic block 120 facing away from the bottom wall of the annular groove 111, so that the rolling member 220 can be disposed on the connector 210 protruding from the side of the non-metallic block 120 facing away from the fixed seat 110. Furthermore, the orthographic projection of the connector 210 on the fixed seat 110 can be located outside the coverage of the mounting surface 101, and the distance between the connector 210 and the mounting surface 101 can be greater than the distance between the non-metallic block 120 and the mounting surface 101, so that the connector 210 does not collide with the product 20 to be hot-melted during the ultrasonic hot-melting process.

[0072] In some embodiments, the connector 210 is not limited to being disposed protruding from the side of the non-metallic block 120 facing away from the fixing seat 110. It is sufficient that the rolling element 220 disposed on the connector 210 protrudes from the side of the non-metallic block 120 facing away from the fixing seat 110. Furthermore, when the connector 210 and the non-metallic block 120 are made of the same material, the distance between the connector 210 and the placement surface 101 can also be equal to the distance between the non-metallic block 120 and the placement surface 101. In other words, the connector 210 can be considered as one of the multiple non-metallic blocks 120, thereby connecting to the rolling element 220 while cooperating with the multiple non-metallic blocks 120 to limit the position of the hot-melt product 20.

[0073] The rolling element 220 is rotatably mounted on the connecting member 210 and can generate rolling friction with the misaligned hot-melt product 20, causing the hot-melt product 20 to change its displacement direction under the action of the rolling element 220, thereby guiding the hot-melt product 20 onto the placement surface 101. The connecting member 210 and the rolling element 220 can be connected by a rotating shaft 230, allowing the rolling element 220 to rotate relative to the connecting member 210. Furthermore, the rotation axis of the rolling element 220 can be parallel to the corresponding side of the placement surface 101, that is, parallel to the extension direction of the corresponding side. This allows the misaligned hot-melt product 20, after being guided by the rolling element 220, to shift toward the side of the placement surface 101 corresponding to the rolling element 220, thereby returning to its correct orientation and continuing to be placed on the placement surface 101.

[0074] Partial areas of the rolling member 220 may be arranged to protrude from the side of the connector 210 facing away from the fixing seat 110, and also from the side of the non-metallic block 120 facing away from the fixing seat 110, so that the height of the rolling member 220 on the placement surface 101 can be higher than the heights of the connector 210 and the non-metallic block 120. With this arrangement, when the hot-melt product 20 is placed in an offset position in the reference direction X, the hot-melt product 20 can directly contact the protruding rolling member 220 and be placed on the placement surface 101 under the guidance of the rolling member 220, thereby reducing the probability of the hot-melt product 20 being scraped against the non-metallic block 120 and the connector 210.

[0075] The rolling member 220 may also be arranged to protrude from the side of the connecting member 210 close to the placement surface 101, and the edge of the orthographic projection of the rolling member 220 on the fixing seat 110 may also be close to or in contact with the edge of the placement surface 101. The rolling member 220 may also be arranged closer to the placement surface 101 than the non-metallic block 120. In this arrangement, when the deviated hot-melt product 20 is corrected by the guidance of the rolling member 220, the hot-melt product 20 can be spaced apart from the side of the non-metallic block 120 facing the placement surface 101, thereby reducing the probability of the hot-melt product 20 scraping against the non-metallic block 120 during placement.

[0076] In the above scheme, the connecting member 210 is arranged between two adjacent non-metallic blocks 120, and a rolling member 220 is arranged on the connecting member 210, and the rolling member 220 is also arranged to protrude from the side of the non-metallic block 120 away from the fixing seat 110, so that the deviated product 20 to be hot-melted can contact the rolling member 220 and be corrected and placed on the placement surface 101 under the guidance of the rolling member 220, so as to reduce the probability of the product 20 to be hot-melted scratching the non-metallic block 120 due to deviation.

[0077] In some embodiments, the rolling element 220 may be a ball or a roller. When the rolling element 220 is a roller, the connecting member 210 and the rolling element 220 may be connected via a rotating shaft 230 so as to limit the rotational freedom of the rolling element 220 by using the rotating shaft 230.

[0078] In the above scheme, by setting the rolling member 220 as a ball or a roller, compared with the rolling member 220 being a roller with a larger area, the contact area between the rolling member 220 and the product to be hot-melted 20 can be reduced, so as to further reduce the probability of the product to be hot-melted 20 being scratched by the rolling member 220.

[0079] In some embodiments, the number of non-metallic blocks 120 may be ten, the number of guide assemblies 200 may be six, and the placement surface 101 may be rectangular in shape, having two oppositely disposed long sides L1 and two oppositely disposed short sides L2. The area where one long side L1 is located may be provided with three spaced-apart non-metallic blocks 120 and two guide assemblies 200, while the area where one short side L2 is located may be provided with two spaced-apart non-metallic blocks 120 and one guide assembly 200, and the guide assembly 200 may be located between two adjacent non-metallic blocks 120.

[0080] It can be understood that the number of non-metallic blocks 120 and guide assemblies 200 can also be adaptively adjusted according to the shape and size of the placement surface 101. Only multiple non-metallic blocks 120 are needed to define the limiting space 102 on the placement surface 101, and each area on each edge of the placement surface 101 is provided with at least one guide assembly 200, rather than being limited to the ten and six in the above-mentioned schemes.

[0081] In some embodiments, when the material of the connector 210 is the same as that of the non-metallic block 120, the fixing assembly 100 may include only the fixing seat 110, and the non-metallic block 120 may be omitted. In this case, multiple guide assemblies 200 may be provided in the area where each side of the placement surface 101 is located. The multiple guide assemblies 200 on each side of the placement surface 101 may also be arranged together around the placement surface 101 like the multiple non-metallic blocks 120, and define the aforementioned limiting space 102 on the placement surface 101, so that the connectors 210 of the multiple guide assemblies 200 can be used to limit the position of the hot-melt product 20 to be treated. In other words, the connectors 210 of the multiple guide assemblies 200 can replace the multiple non-metallic blocks 120 to limit the position of the hot-melt product 20 to be treated, and the arrangement of the connectors 210 on the fixing seat 110 can be the same or similar to the arrangement of the non-metallic blocks 120 on the fixing seat 110 in the aforementioned embodiment.

[0082] In some embodiments, when the material of the connector 210 is the same as that of the non-metallic block 120, the guide assembly 200 may include only the rolling element 220, and the design of the connector 210 may be omitted. In this case, the non-metallic block 120 may replace the connector 210 to serve as the mounting mechanism for the rolling element 220. The rolling element 220 may be rotatably mounted on the non-metallic block 120, and the arrangement of the rolling element 220 on the non-metallic block 120 may be the same as or similar to the arrangement of the rolling element 220 on the connector 210. Of course, considering cost issues, only some of the multiple non-metallic blocks 120 may be equipped with the rolling element 220, and it is not necessary to have the rolling element 220 on all non-metallic blocks 120. It is only necessary to have at least one rolling element 220 on each edge of the placement surface 101.

[0083] In some embodiments, in addition to guiding the hot melt product 20 by rolling friction, the guide assembly 200 can also guide the hot melt product 20 by sliding friction. For example, the guide assembly 200 may only include: a connector 210. Figure 7 As shown, the portion of the connector 210 protruding from the non-metallic block 120 may have an inclined surface 211 tilted relative to the reference direction X. This inclined surface 211 can generate sliding friction with the deflected hot-melt product 20 and guide the hot-melt product 20 onto the placement surface 101. Furthermore, the portion of the connector 210 forming the inclined surface 211 may also protrude from the side of the non-metallic block 120 closer to the placement surface 101. This allows the hot-melt product 20 to be spaced from the side of the non-metallic block 120 closer to the placement surface 101 after being guided and separated from the inclined surface 211, thereby reducing the likelihood of scratches between the hot-melt product 20 and the non-metallic block 120. Furthermore, to address the potential for scratches on the hot-melt product 20 caused by high sliding friction, a flexible layer 212 may be provided on the inclined surface 211 of the connector 210 to minimize the likelihood of scratches on the hot-melt product 20.

[0084] See also Figures 8 and 9 , Figure 8 yes Figure 1 A schematic structural diagram of the positioning tool 10 from another perspective, Figure 9 yes Figure 8 A local enlarged schematic diagram of point A in the middle.

[0085] In addition to limiting the hot melt product 20 by the non-metallic block 120, the fixing assembly 100 may also include a limiting bracket 140. Figures 8 and 9 As shown, the limiting bracket 140 is movably arranged on the side of the non-metallic block 120 away from the fixing seat 110 and can contact the product to be hot-melted 20 to limit the displacement of the product to be hot-melted 20 in a direction parallel to the placement surface 101.

[0086] When the non-metallic block 120 is disposed in the annular groove 111, the limiting bracket 140 can be disposed on a side of the non-metallic block 120 that faces away from the bottom wall of the annular groove 111, and can be moved away from the non-metallic block 120 by an external structure, such as a robot arm or a cylinder with a suction nozzle, etc. The moving direction of the limiting bracket 140 can also be parallel to the reference direction X. At the same time, when the limiting bracket 140 is located on the non-metallic block 120, the limiting bracket 140 can contact the portion of the product to be hot-melted 20 that protrudes from the side of the non-metallic block 120 that faces away from the bottom wall of the annular groove 111, and limit the portion of the product to be hot-melted 20 that protrudes from the non-metallic block 120, so as to reduce the probability of misalignment of structural components in the product to be hot-melted 20 during the hot-melting process.

[0087] In the above scheme, by arranging a removable limiting bracket 140 on the side of the non-metallic block 120 away from the fixing seat 110, the limiting bracket 140 can be moved away from the product to be hot-melt 20, and after the product to be hot-melt 20 is placed on the placement surface 101, the limiting bracket 140 is reset to limit the partial area of ​​the product to be hot-melt 20 protruding from the non-metallic block 120, so as to reduce the probability of dislocation of structural parts in the product to be hot-melt 20 during the hot-melting process.

[0088] In some embodiments, the placement surface 101 may have an angle 1011, and the limiting bracket 140 may contact the product to be hot-melted 20 at the angle 1011, and limit the displacement of the product to be hot-melted 20 in the extension direction of the two sides of the placement surface 101 forming the angle 1011.

[0089] The limiting bracket 140 may include a first limiting portion 141 and a second limiting portion 142. The first limiting portion 141 may contact the product 20 to be hot-melted in the direction of the side of the placement surface 101 that forms the angle 1011, such as the direction of the long side L1, and limit the displacement of the product 20 to be hot-melted in the direction of that side. Similarly, the second limiting portion 142 may contact the product 20 to be hot-melted in the direction of the other side of the placement surface 101 that forms the angle 1011, such as the direction of the short side L2, and limit the displacement of the product 20 to be hot-melted in the direction of that other side.

[0090] In the above scheme, a limiting bracket 140 is provided to contact the product to be hot-melted 20 at the angle 1011 of the placement surface 101, and the displacement of the product to be hot-melted 20 is limited in the extension direction of the two sides of the placement surface 101 forming the angle 1011, so that the limiting bracket 140 can simultaneously limit the displacement of the product to be hot-melted 20 in two directions at the angle 1011, which is conducive to improving the layout flexibility of the limiting bracket 140, so that the limiting bracket 140 can avoid the guide assembly 200.

[0091] In some embodiments, when the placement surface 101 is rectangular, the placement surface 101 may have two opposing long sides L1 and two opposing short sides L2, and the two long sides L1 may intersect with the two short sides L2 to form four angles 1011. Furthermore, there may be two position-limiting brackets 140, each located at one of the two short sides L2. A single position-limiting bracket 140 may contact the product 20 to be hot-melted at two angles 1011 adjacent to the short sides L2.

[0092] The limiting bracket 140 can be provided corresponding to the short side L2, and the opposite ends of the limiting bracket 140 can respectively contact the hot-melt product 20 at two included angles 1011 adjacent to the short side L2, thereby limiting the position of the hot-melt product 20. Furthermore, a notch 143 can be provided between the opposite ends of the limiting bracket 140 to allow the guide assembly 200 located at the short side L2 to avoid the hot-melt product 20.

[0093] In the above scheme, compared with setting four limiting brackets 140 to limit the hot-melt product 20 at the four corners 1011 respectively, by setting a single limiting bracket 140, it is possible to contact the hot-melt product 20 at the two corners 1011 adjacent to the short side L2, so that only two limiting brackets 140 are needed at the four corners 1011 to complete the limiting of the hot-melt product 20, which helps to reduce the number of limiting brackets 140.

[0094] Please combine Figure 2 and Figure 9 See Figure 10 , Figure 10 yes Figure 1 Schematic diagram of the exploded structure of the hot-melt product 20.

[0095] like Figure 10 As shown, the product 20 to be hot-melted provided in the embodiment of the present application can be a battery top cover, and the product 20 to be hot-melted can include: a top cover sheet 21 and a lower plastic 22. Among them, the top cover sheet 21 can be placed on the placement surface 101, and can be guided by the guide component 200 to be transferred to the placement surface 101 when it is offset. A plurality of non-metallic blocks 120 can restrict the top cover sheet 21 on the placement surface 101. The lower plastic 22 can be placed on the side of the top cover sheet 21 away from the placement surface 101, and protrude from the side of the non-metallic block 120 away from the fixing seat 110. The limiting bracket 140 can contact the lower plastic 22 to limit the displacement of the lower plastic 22 in a direction parallel to the placement surface 101.

[0096] like Figure 2 As shown, before placing the top cover sheet 21, the limiting bracket 140 can be removed first, and after removing the limiting bracket 140, the top cover sheet 21 can be placed on the placement surface 101 by a manipulator. When the top cover sheet 21 is placed off-center, the top cover sheet 21 can contact the rolling element 220 of the guide assembly 200 and generate rolling friction with the rolling element 220, so as to be placed on the placement surface 101 under the guidance of the rolling element 220, thereby reducing the probability of the top cover sheet 21 being scratched by the non-metallic block 120 due to the off-center placement. At the same time, after the top cover sheet 21 is placed on the placement surface 101, multiple non-metallic blocks 120 can limit the top cover sheet 21, thereby reducing the probability of the top cover sheet 21 being misaligned with the lower plastic 22 due to vibration during the ultrasonic hot melting process.

[0097] After the top cover 21 is placed, the lower plastic 22 can also be placed on the side of the top cover 21 away from the placement surface 101 by a robot. Figure 2 and Figure 9 As shown, after the lower plastic 22 is placed on the top cover sheet 21, the stacking of the two will cause at least a portion of the lower plastic 22 to protrude from the side of the non-metallic block 120 away from the fixing seat 110. Therefore, it is necessary to move the limiting bracket 140 back to the non-metallic block 120 and use the limiting bracket 140 to contact the lower plastic 22 at the angle 1011 to limit the lower plastic 22, thereby reducing the probability of the lower plastic 22 being misaligned with the top cover sheet 21 due to vibration during the ultrasonic hot melting process.

[0098] Furthermore, after the lower plastic 22 is placed, the ultrasonic furnace head can be pressed against the side of the lower plastic 22 facing away from the top cover sheet 21, and can drive the lower plastic 22 and the top cover sheet 21 to rub, so that the side of the lower plastic 22 in contact with the top cover sheet 21 is melted, thereby being welded together with the top cover sheet 21.

[0099] Finally, in some specific application scenarios, in order to address the problem that the top cover sheet of the existing battery top cover scrapes against the positioning tool due to deviation, resulting in a reduced yield of the finished battery top cover, the positioning tool 10 provided in this application may include: a fixing component 100 and a guide component 200; the fixing component 100 has a placement surface 101 for placing the product 20 to be hot-melted, and the guide component 200 is provided on the fixing component 100, and at least one guide component 200 is provided in the area where each edge of the placement surface 101 is located; when the product 20 to be hot-melted is deviated, the guide component 200 can generate rolling friction with the deviated product 20 to be hot-melted, and guide the product 20 to be hot-melted to the placement surface 101.

[0100] The fixing assembly 100 includes a fixing base 110 and a plurality of non-metallic blocks 120. The fixing base 110 has a placement surface 101. The plurality of non-metallic blocks 120 are arranged on the fixing base 110 at intervals and are arranged around the placement surface 101 to limit the displacement of the product 20 to be hot-melted on the placement surface 101. The guide assembly 200 includes a connecting member 210 and a rolling member 220. The connecting member 210 is arranged on the fixing base 110 and is located between two adjacent non-metallic blocks 120. The rolling member 220 is rotatably arranged on the connecting member 210 and protrudes from the side of the non-metallic block 120 facing away from the fixing base 110. When the product 20 to be hot-melted is deviated, the rolling member 220 can generate rolling friction with the product 20 to guide the product 20 to the placement surface 101.

[0101] The positioning tool 10 provided in the embodiment of the present application has a placement surface 101 of the fixing component 100 for placing the product to be hot-melted 20, and each side of the placement surface 101 is provided with at least one guide component 200. The guide component 200 can guide the product to be hot-melted 20 when the product to be hot-melted 20 is deviated, and guide the product to be hot-melted 20 to the placement surface. Therefore, the guide component 200 can be used to reduce the probability of the product to be hot-melted 20 scratching the fixing component 100 due to deviation, thereby improving the finished product yield of the product to be hot-melted 20.
