[0037] In addition, if the terms "first", "second" and the like appear, they are only used for differentiation description, and cannot be understood as indicating or implying relative importance.

[0038] It should be noted that the features in the embodiments of the utility model can be combined with each other without conflict.

[0039] Please refer to Figure 1 and Figure 2 , Figure 1 the structure schematic view of the glue solidification prevention device 200 provided for the embodiment; Figure 2 the structure schematic view of the fixing tool 100 provided for the embodiment.

[0040] The embodiment provides a glue solidification prevention device 200, which comprises a glue bucket 210, a hydraulic cylinder 220, a glue pressing disc 230 and a fixing tool 100; the fixing ends of the glue bucket 210 and the hydraulic cylinder 220 are arranged on the fixing tool 100; the movable end of the hydraulic cylinder 220 is connected with the glue pressing disc 230; the glue pressing disc is movably matched with the glue bucket 210 under the driving of the hydraulic cylinder 220.

[0041] The glue is contained in the glue bucket 210, the glue pressing disc 230 is driven by the hydraulic cylinder 220 to extend into the glue bucket 210 and contact the glue in the glue bucket 210, so that the glue is prevented from contacting air and reacting to solidify; at this time, the glue pressing disc 230 is located in the glue bucket 210, that is, the glue pressing disc 230 seals the glue bucket 210.

[0042] However, when the gluing is needed, the pressing plate 230 needs to be separated from the glue bucket 210 to open the glue bucket 210, so as to take the glue from the glue bucket 210 to glue the battery module. In order to avoid the glue bucket 210 moving with the pressing plate 230 under the influence of the viscosity of the glue and the friction between the pressing plate 230 and the glue bucket 210, which results in the failure of opening the glue bucket 210 and affects the gluing, the fixed tool 100 is arranged to fix the glue bucket 210 to avoid the displacement of the glue bucket 210, so that the pressing plate 230 and the glue bucket 210 can be separated to take the glue for gluing.

[0043] It should be noted that in the process of gluing the battery module, a plurality of glues are generally needed, and therefore, the glue solidification prevention device 200 in the embodiment is provided with two glue buckets 210 to accommodate different glues respectively. Each glue bucket 210 corresponds to a pressing plate and a fixed tool 100. The two pressing plates 230 are arranged at the movable end of the same hydraulic cylinder 220, so that the two pressing plates 230 can move synchronously to open or close the glue bucket 210.

[0044] In other embodiments, two hydraulic cylinders 220 can be arranged, and the two pressing plates 230 correspond to the two hydraulic cylinders 220 respectively, so that when a glue is needed, the corresponding glue bucket 210 accommodating the glue is opened.

[0045] According to the above, the fixed tool 100 in the embodiment includes a bottom plate 110, a locking ring 130 and at least one claw assembly 120. The bottom plate 110 is used to place the glue bucket 210. The claw assembly 120 is movably connected to the bottom plate 110, and the claw assembly 120 is used to fix the glue bucket 210. The locking ring 130 cooperates with the claw assembly 120 to lock or unlock the claw assembly 120.

[0046] It can be understood that after the glue bucket 210 is placed on the bottom plate 110, the claw assembly 120 is rotated to approach the glue bucket 210, so that the claw assembly 120 abuts against the peripheral wall of the glue bucket 210 to fix the glue bucket 210. Subsequently, the locking ring 130 is used to lock the claw assembly 120 to limit the movement of the claw assembly 120, so as to fix the glue bucket 210, avoid the glue bucket 210 moving with the pressing plate 230 when the pressing plate 230 moves upward under the drive of the hydraulic cylinder 220, and enable the pressing plate 230 and the glue bucket 210 to be separated to open the glue bucket 210 to take the glue for gluing the battery module.

[0047] Please refer to Figure 1 and Figure 2Specifically, after the clamping jaw assembly 120 and the circumferential wall of the glue bucket 210 abut against each other, the locking ring 130 is matched with the clamping jaw assembly 120, and then is fixed by using the bolt. In this way, the locking of the clamping jaw assembly 120 is completed, and the movement of the glue bucket 210 is avoided. When the glue bucket 210 needs to be taken out, the bolt and the locking ring 130 are sequentially removed, so as to unlock the clamping jaw assembly 120, and then the glue bucket 210 is taken out.

[0048] It should be noted that in the embodiment, the number of the clamping jaw assemblies 120 is four, and the clamping jaw assemblies 120 are arranged circumferentially around the axis of the glue bucket 210, so as to improve the stability of the glue bucket 210. In other embodiments, the number of the clamping jaw assemblies 120 can be adjusted according to specific conditions.

[0049] Further, referring to Figures 1-6 , Figure 3 is a partial enlarged view of A in FIG. 12; Figure 2 is a partial enlarged view of B in FIG. 12; Figure 4 is a structural schematic view of the clamping jaw 122 provided in the embodiment; Figure 2 is a structural schematic view of the base 121 provided in the embodiment. Figure 5 Figure 6 The clamping jaw assembly 120 in the embodiment comprises a base 121, a clamping jaw 122 and a rotating shaft 123. The base 121 is connected to the bottom plate 110. One end of the clamping jaw 122 is movably connected to the base 121 through the rotating shaft 123. The other end of the clamping jaw 122 is provided with an abutting portion 1221 protruding towards the glue bucket 210. The abutting portion 1221 is used for abutting against the circumferential wall of the glue bucket 210.

[0050] Specifically, the base 121 is provided with an avoiding groove 1211 and a connecting hole 1212. One end of the clamping jaw 122 is provided with a through hole 1224. One end of the clamping jaw 122 is inserted into the avoiding groove 1211, so that the axis of the through hole 1224 coincides with the axis of the connecting hole 1212. The rotating shaft 123 passes through the connecting hole 1212 and the through hole 1224, so that the clamping jaw 122 can rotate around the axis of the rotating shaft 123.

[0051] It should be noted that the rotating shaft 123 in the embodiment is a bolt, and the connecting hole 1212 is a threaded hole to threadedly cooperate with the bolt. That is, the bolt is fixedly connected to the base 121, and the through hole 1224 movably cooperates with the bolt, so that the clamping jaw 122 can rotate around the axis of the bolt. In other embodiments, other structures can be used to connect the base 121 and the rotating shaft 123, and movably connect the rotating shaft 123 and the clamping jaw 122.

[0052] It should be noted that the rotating shaft 123 in the embodiment is a bolt, and the connecting hole 1212 is a threaded hole to threadedly cooperate with the bolt. That is, the bolt is fixedly connected to the base 121, and the through hole 1224 movably cooperates with the bolt, so that the clamping jaw 122 can rotate around the axis of the bolt. In other embodiments, other structures can be used to connect the base 121 and the rotating shaft 123, and movably connect the rotating shaft 123 and the clamping jaw 122.

[0053] ​The other end of the clamping jaw 122 is provided with an abutting portion 1221 protruding towards the glue bucket 210, so that the abutting portion 1221 can abut against the peripheral wall of the glue bucket 210 in the process of the clamping jaw 122 approaching the glue bucket 210. In combination with Figure 2 , the base 121 is spaced apart from the periphery of the glue bucket 210, and the width of the base 121 is greater than the width of the clamping jaw 122. Thus, the embodiment fixes the glue bucket 210 by providing the abutting portion 1221 to ensure that the clamping jaw 122 can abut against the glue bucket 210.

[0054] In other embodiments, the width of the clamping jaw 122 can also be greater than the width of the base 121, so that by providing the abutting portion 1221, other parts of the clamping jaw 122 are prevented from abutting or rubbing against the peripheral wall of the glue bucket 210 in the process of the clamping jaw 122 moving, affecting the movement of the clamping jaw 122, and avoiding affecting the service life of the glue bucket 210.

[0055] According to the above structure, please refer to Figures 1-6 , the peripheral wall of the glue bucket 210 is provided with an annular protrusion 211, and the abutting portion 1221 is provided with a clamping groove 1222 for clamping cooperation with the annular protrusion 211 on the peripheral wall of the glue bucket 210. Understandably, in the process of the glue pressing disc 230 moving along the vertical direction driven by the hydraulic cylinder 220, the glue bucket 210 cannot move upwards due to the clamping cooperation of the annular protrusion 211 and the clamping groove 1222, thereby achieving the limiting of the glue bucket 210, so that the glue pressing disc can be separated from the glue bucket 210.

[0056] In addition, the other end of the clamping jaw 122 is also provided with a matching groove 1223, the recess direction of the matching groove 1223 is the same as the protruding direction of the abutting portion 1221, when the lock ring 130 is used to lock the clamping jaw 122, the lock ring 130 is placed in the matching groove 1223, so that the lock ring 130 and the matching groove 1223 are clamped, avoiding the lock ring 130 from sliding down under the influence of gravity, so that the lock ring 130 can lock the clamping jaw 122, further fixing the glue bucket 210, avoiding the glue bucket 210 from moving with the glue pressing disc 230, thereby taking out the glue to coat the battery module.

[0057] It should be noted that the glue bucket 210 in the embodiment has two annular protrusions 211 spaced apart, and each annular protrusion 211 corresponds to a clamping groove 1222 for clamping cooperation. In other embodiments, the number of annular protrusions 211 and clamping grooves 1222 can be adjusted according to actual conditions.

[0058] Further, please refer to Figures 1-7 , Figure 7A structure schematic view of the bottom plate 110 is provided for the embodiment. The bottom plate 110 in the embodiment is provided with a containing groove 111 for containing the glue bucket 210, and the claw assembly 120 is arranged at the groove edge of the containing groove 111. Moreover, the fixing tool 100 further comprises an annular limiting piece 140, which is connected to the bottom plate 110 and connected with the claw assembly 120; the annular limiting piece 140 is sleeved on the glue bucket 210.

[0059] Specifically, the containing groove 111 and the annular limiting piece 140 are utilized to limit the movement of the glue bucket 210 in the horizontal direction, so as to avoid the displacement of the glue bucket 210 under the interference of external force, thereby enabling the pressing disc 230 to enter the glue bucket 210 when the glue bucket 210 needs to be closed, so as to isolate the glue and air and avoid the solidification of the glue.

[0060] It should be noted that the base 121 in the embodiment is arranged on the annular limiting piece 140, and the axis of the annular limiting piece 140 coincides with the axis of the glue bucket 210. Since two glue buckets 210 are arranged in the embodiment to contain different glues, two containing grooves 111 are arranged on the bottom plate 110, and the number of the annular limiting pieces 140 is also two.

[0061] In summary, the glue solidification prevention device 200 comprises the pressing disc 230 which can be driven to move by the hydraulic cylinder 220, so that the pressing disc 230 can close the glue bucket 210, thereby avoiding the contact between the glue and air in the glue bucket 210 to solidify. When the battery module needs to be glued, the claw assembly 120 and the locking ring 130 in the fixing tool 100 can fix the glue bucket 210, so that the glue bucket 210 will not move together with the pressing disc 230, thereby opening the glue bucket 210 to take out the glue in the glue bucket 210 to glue the battery module.

[0062] The above merely describes the specific embodiments of the utility model, but the protection scope of the utility model is not limited to this. Any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
