DETAILED DESCRIPTION

[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0036] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0037] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the utility model product is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0038] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0039] The terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0041] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0042] During the battery module production and assembly process, to ensure safety and performance, the heating wire must be flatly laid and fixed within the grooves of the current collector. Glue is then applied to the heating wire surface to ensure electrical and thermal conductivity. Currently, this process is done automatically using automatic glue applicators. However, sometimes malfunctions in the automatic glue applicator or the back-end glue supply equipment cannot be quickly repaired, resulting in long maintenance wait times. During this time, the heating wire cannot be glued and fixed, severely impacting production efficiency.

[0043] In view of this, the battery module gluing tool provided in the embodiments of the present invention can solve the above-mentioned problems. The gluing tool can apply glue to various types of battery modules. The difference is that the gluing tool must adapt to the structure and layout of the battery module. Of course, the gluing tool is not limited to applying glue to battery modules and can also be used in other scenarios requiring gluing. It will be described in detail below.

[0044] Please refer to Figures 1 to 4 The battery module gluing tooling includes a positioning plate 1, a limiting assembly 2, and a scraper 3. The positioning plate 1 is connected to the battery module 4 and is used to provide positioning for the gluing operation and improve the accuracy of the gluing. The limiting assembly 2 is used to limit the gluing range of the gluing component to prevent large deviations in the gluing position during gluing. The gluing component here is the execution component of the gluing. After the gluing component is finished, the scraper 3 is used to scrape the glue applied to the battery module 4 flat and evenly, so that the quality of the applied glue meets the requirements.

[0045] It should be noted that in this embodiment, the glue applicator is a device for applying glue to the battery module 4. An electric glue gun or a manual glue gun can be used. In this embodiment, the electric glue gun is used as an example. Whether it is an electric glue gun or a manual glue gun, a single glue can be used for application, or a mixture of multiple glues can be used for application. The type of glue used depends on the specific situation. In addition, in this embodiment, the battery module 4 is glued to the grooves of the current collector where the heating wire 40 is arranged and the heating wire 40. The glue needs to completely cover the heating wire 40.

[0046] Continue to refer Figure 1 and Figure 3 The positioning plate 1 is provided with a guide groove 10 that extends through the positioning plate 1 and aligns with the path of the heating wire 40. The positioning plate 1 is mounted on the battery module 4 so that the guide groove 10 is located above the heating wire 40. The glue gun outlet pipe 5 of the electric glue gun can pass through the guide groove 10 to apply glue to the heating wire 40 and the groove of the current collector.

[0047] In order to facilitate installation of the positioning plate 1 on the battery module 4 and removal from the battery module 4 after gluing, a handle 14 is provided on the positioning plate 1 , and the operator can hold the handle 14 for quick installation and removal.

[0048] There are many ways to connect the positioning plate 1 and the battery module 4, such as threaded connection, latch connection, clamping connection, etc. In this embodiment, a plurality of positioning posts 13 are provided at the bottom of the positioning plate 1, and a plurality of positioning holes 41 are provided on the battery module 4. The positioning holes 41 match the positions of the positioning posts 13 and the sizes of the positioning holes 41 also match the positioning posts 13, so that the positioning posts 13 can be plugged into the positioning holes 41, thereby fixing the positioning plate 1 on the battery module 4. After being fixed, the positioning plate 1 and the battery module 4 will not move relative to each other, thereby ensuring that the guide groove 10 is always consistent with the laying path of the heating wire 40, ensuring the accuracy of the electric glue gun when applying glue.

[0049] Of course, the positioning plate 1 can be set as an integrated type or a split type. The integrated positioning plate 1 is convenient for installation, and the split positioning plate 1 can more easily arrange other gluing auxiliary components. In this embodiment, the positioning plate 1 is a split type.

[0050] Specifically, refer to Figure 5 and Figure 6 The positioning plate 1 includes a base plate 11 and a cover plate 12. The cover plate 12 and the base plate 11 are detachably connected, such as by bolts, latches, screws, etc. A first through-slot 110 is defined on the base plate 11, and a second through-slot 120 is defined on the cover plate 12. The first through-slot 110 corresponds to the second through-slot 120. The first through-slot 110 and the second through-slot 120 have the same slot width. The same slot width prevents the glue gun outlet hose 5 from moving in the slot width direction, ensuring accurate glue application. The first through-slot 110 and the second through-slot 120 cooperate to form the guide slot 10.

[0051] To secure the scraper 3 to the positioning plate 1, a widening groove 111 is formed on the base plate 11. This groove 111 serves to constrain the scraper 3, preventing it from moving in the depth direction of the groove, ensuring a uniform thickness of the glue during scraping. The width of the widening groove 111 is greater than that of the first through-groove 110 and the second through-groove 120. The widening groove 111 is located on the side closest to the cover plate 12. The scraper 3 is used to smooth the glue, so it must pass through the first through-groove 110 and the second through-groove 120 in sequence.

[0052] refer to Figure 7 and Figure 8The scraper 3 includes a scraper 30, a vertical rod 31, a limiting slider 32, and a fixing bracket 33. The scraper 30 is connected to the bottom end of the vertical rod 31 and is used to scrape off excess glue. The limiting slider 32 is set on the outer wall of the vertical rod 31 and slides in the widened groove 111. The sliding of the limiting slider 32 drives the vertical rod 31 and the scraper 30 to move. The top end of the vertical rod 31 extends to the cover plate 12. The fixing bracket 33 is set at the top end of the vertical rod 31. The operator can easily pull the fixing bracket 33 to slide on the surface of the cover plate 12, thereby driving the vertical rod 31, the limiting slider 32 and the scraper 30 to move together to scrape off excess glue.

[0053] Furthermore, the scraper 30 comprises a plug-in cylinder and a plate body. The plug-in cylinder is plugged into the vertical rod 31, and the plate body is connected to the plug-in cylinder. The side of the plate body that scrapes the glue is a straight edge. Of course, in order to make the scraper 30 wider than the width of the first through-slot 110, the first through-slot 110 on the bottom plate 11 is chamfered, and the upper side of the scraper 30 is also tilted accordingly.

[0054] Furthermore, the limiting slider 32 is a sliding bearing with external threads, that is, the circumferential outer wall of the sliding bearing is provided with external threads, and the external threads can form a rotational sliding movement with the groove wall of the widened groove 111.

[0055] When using an electric glue gun to apply glue, although the glue gun outlet pipe 5 can be limited by the guide groove 10, it is not easy to control the depth of the glue application in the depth direction, which can easily lead to differences in the amount of glue at the heating wire 40 in different parts. In order to solve this problem, a limiting component 2 is provided. The limiting component 2 not only limits the distance between the glue gun outlet pipe 5 and the collecting plate, but also limits the range of the glue application.

[0056] refer to Figure 9 The limiting assembly 2 includes a sliding member 20 and a locking member 21. The locking member 21 is arranged on the sliding member 20. The sliding member 20 is slidably connected to the positioning plate 1. The locking member 21 is fixed on the glue gun outlet pipe 5.

[0057] Specifically, the sliding member 20 is a U-shaped structural member, the bottom of which is provided with a through-hole 201 through which the glue gun discharge hose 5 passes. The locking member 21 is a bolt, with screw holes provided on both sides of the U-shaped structural member. The bolt is inserted into the screw holes and threadedly connected to the U-shaped structural member. The end face of the bolt faces the glue gun discharge hose 5. Before applying glue using the electric glue gun, the glue gun discharge hose 5 is passed through the through-hole 201, and the U-shaped structural member is adjusted to a suitable position on the glue gun discharge hose 5. The bolt is then tightened so that the end face of the bolt is pressed against the glue gun discharge hose 5, thereby positioning the limit assembly 2 on the glue gun discharge hose 5. When applying glue using the electric glue gun, because the U-shaped structural member slides against the cover plate 12, the distance between the glue gun discharge hose 5 and the heating wire 40 remains constant, thereby avoiding inconsistent glue application amount and application range caused by changes in the depth direction of the glue gun discharge hose 5 in the guide groove 10.

[0058] The U-shaped structure of the sliding member 20 described above is merely an example. The sliding member 20 may also be in a block shape, with the side of the block-shaped sliding member 20 that contacts the cover plate 12 being flat, thereby enabling the sliding member 20 to slide stably on the surface of the cover plate 12. The block-shaped sliding member 20 also has a through hole 201 through which the glue gun discharge hose 5 passes, and a screw hole for connecting the locking member 21. The axial direction of the screw hole is perpendicular to the axial direction of the through hole 201. The locking member 21 is a bolt, and the end surface of the bolt is pressed against the glue gun discharge hose 5 to position and fix the limit assembly 2.

[0059] Of course, the limiting component 2 can also be set to other forms. Its function is to ensure that the distance between the glue gun outlet pipe 5 and the collecting plate is always constant when it moves along the guide groove 10, thereby ensuring that the glue amount and glue coating range at various locations of the heating wire 40 are consistent.

[0060] To sum up, when using the glue coating tooling provided in this embodiment, first install the positioning plate 1 on the battery module 4 so that the guide groove 10 is located above the heating wire 40, and then install the limit assembly 2 at a suitable position on the glue gun glue outlet pipe 5. The glue gun glue outlet pipe 5 is inserted into the guide groove 10 and moves along the guide groove 10 at a constant speed to apply the mixed glue to the collector plate groove and the heating wire 40. After the coating is completed, the handheld fixing frame 33 is pulled to scrape the glue flat so that the coated glue meets the production quality requirements.

[0061] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
