[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] In order to illustrate the technical solution described in this application, a specific embodiment is provided below for illustration.

[0033] See also Figures 1 to 9 As shown, an embodiment of the present application provides a fixture for assembling a lower plastic, including: an upper mold 12, a lower mold 11 and a driving mechanism 14, the lower mold 11 is used to place a top cover sheet 15 and a lower plastic 16, and the driving mechanism 14 is used to drive the upper mold 12 to move toward the lower mold 11 to assemble the lower plastic 16 to connect the top cover sheet 15.

[0034] Specifically, the top cover sheet 15 is provided with a first liquid injection hole 151, the lower plastic 16 is provided with a second liquid injection hole 162 corresponding to the first liquid injection hole 151, a boss 161 is protruding downward around the hole wall of the second liquid injection hole 162, and a through hole 163 connected to the second liquid injection hole 162 is provided on the side of the boss 161, the lower mold 11 is provided with a groove 112 cooperating with the boss 161, and limit blocks 111 are also provided at both ends of the lower mold 11.

[0035] The upper mold 12 includes a control mechanism, telescopic blocks 122 disposed at both ends of the upper mold 12 , and an elastic member 121 disposed toward the lower mold 11 . The control mechanism connects the elastic member 121 and the telescopic blocks 122 .

[0036] Among them, the elastic member 121 is used to extend into the first liquid injection hole 151 when the top cover piece 15 is not installed upside down, and is used to shrink and trigger the control mechanism to control the telescopic block 122 to extend out of the upper mold 12 when the top cover piece 15 is installed upside down. When the telescopic block 122 extends out of the upper mold 12, the telescopic block 122 is supported and limited by the limit block 111.

[0037] In some embodiments, the fixture for assembling the lower plastic further includes a guide post 13 , and the upper mold 12 is sleeved on the guide post 13 and can slide up and down along the guide post 13 .

[0038] In some embodiments, the driving mechanism 14 is a motor or a cylinder.

[0039] In some embodiments, the boss 161 is U-shaped.

[0040] In some embodiments, the elastic member 121 is a probe.

[0041] The working principle of the clamp for assembling the lower plastic provided in the above embodiment is:

[0042] (1) When placing the lower plastic 16 on the lower mold 11, the cooperation between the boss 161 and the groove 112 can be used to achieve a foolproof design to prevent the lower plastic 16 from being installed upside down.

[0043] (2) When the top cover sheet 15 is placed on the lower plastic 16, the elastic member 121, the control mechanism, the telescopic block 122 and the limit block 111 can be used to achieve a foolproof design to prevent the top cover sheet 15 from being installed upside down.

[0044] For example, when the top cover sheet 15 is not reversed, the driving mechanism 14 drives the upper mold 12 to move toward the lower mold 11 to assemble the lower plastic 16 to connect the top cover sheet 15 , and the elastic member 121 extends into the first injection hole 151 , and assembly can be successfully achieved.

[0045] For example, when the top cover piece 15 is placed upside down and the driving mechanism 14 drives the upper mold 12 to move toward the lower mold 11, the elastic member 121 cannot extend into the first injection hole 151, and the elastic member 121 touches the surface of the top cover piece 15 and contracts, thereby triggering the control mechanism to control the telescopic block 122 to extend out of the upper mold 12. When the telescopic block 122 extends out of the upper mold 12, the telescopic block 122 will be supported and limited by the limit block 111, preventing the upper mold 12 from continuing to descend, thereby interrupting the assembly and preventing the top cover piece 15 from being installed upside down.

[0046] It should be noted that the elastic member 121 provided in the embodiment of the present application may be a probe. When the probe touches the surface of the top cover sheet 15 and contracts, a control signal (such as a switch signal) may be issued to trigger the control mechanism to control the telescopic block 122 to extend.

[0047] It should be understood that the embodiment of the present application does not specifically limit the specific structure of the control mechanism and how the control mechanism controls the telescopic block 122, and technicians can set them according to actual needs.

[0048] As an example, the control mechanism is hidden inside the upper mold 12 .

[0049] It should also be noted that the boss 161 provided in the embodiment of the present application is U-shaped and can be arranged opposite the second injection hole 162, so that the boss 161 can not only cooperate with the groove 112 to achieve a fool-proof design, but also can be used to reduce the injection pressure during injection, so that the electrolyte flows into the battery cell from the side through hole 163.

[0050] In summary, the clamp for assembling the lower plastic provided in the embodiment of the present application can replace the manual assembly of the lower plastic 16, and utilizes the cooperation of the boss 161 and the groove 112, as well as the cooperation of the elastic member 121, the control mechanism, the telescopic block 122 and the limit block 111 to achieve a fool-proof design, which can prevent the lower plastic 16 and the top cover piece 15 from being installed upside down, thereby improving product quality.

[0051] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
