[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] The present invention provides Figure 1-4 ,

[0031] A quick-change heat sealing tool comprises a cover lifting and positioning mechanism, a battery shell cover 6, an upper heat sealing plate 7 and a lower heat sealing plate 8. The cover lifting and positioning mechanism comprises a mounting plate 1, a first limiting plate 101, a limiting pin 102, a battery cover limiting seat 4 and a second limiting plate 5. A first limiting plate 101 is provided at the bottom of the mounting plate 1, limiting pins 102 are provided at both ends of one side of the first limiting plate 101, and limiting pins 102 are provided on the front and back of the first limiting plate 101; the mounting plate 1 and the first limiting plate 101 are locked and fixed by four limiting pins 102.

[0032] The function of the first limiting plate 101 is to provide a reference positioning for the limiting assembly of the battery shell cover 6 to ensure the relative position consistency between the lifting mechanism and the battery shell cover 6.

[0033] The limit pins 102 are used to fine-tune the horizontal and vertical position of the first limit plate 101 to ensure accurate alignment with other equipment components. After debugging is completed, they are locked to avoid repeated adjustments during subsequent model changes.

[0034] When installing the first limit plate 101, it needs to be debugged and installed: when the first limit plate 101 is adjusted, the position is adjusted through the four limit pins 102. After the initial debugging is successful, the limit pins 102 are locked; and when the model is changed again later, the entire lid lifting and positioning mechanism can be directly installed on the equipment through the installation plate 1 without the need for further debugging.

[0035] Mounting holes 103 are formed around the top of the mounting plate 1, and the mounting holes 103 are secured to the external device via a clamping rod. A battery cover retaining seat 4 is provided below the bottom of the first retaining plate 101. Support rods 2 are mounted around the bottom of the first retaining plate 101, and the battery cover retaining seat 4 is fixedly mounted to the bottom of the support rods 2. A second retaining plate 5 is provided around the bottom of the battery cover retaining seat 4, and the battery cover retaining seat 4 and the second retaining plate 5 are secured to each other via screws 501. The provision of the second retaining plate 5 and screws 501 facilitates regular replacement or maintenance of the second retaining plate 5 at the bottom of the battery cover retaining seat 4, thereby extending its service life.

[0036] The present invention provides a battery cover limit seat 4, a second limit plate 5 and a screw 501 and other components for use in conjunction, thereby facilitating the precise positioning of the battery shell cover 6 during hot melting, thereby improving the quality of the heat sealing production of the battery shell cover 6; and also facilitating improving the effect of hot melting of the battery shell cover 6.

[0037] The second limiting plate 5 is used to adjust the position of the battery shell cover 6 after it is lifted. After the initial debugging is successful, the cover lifting mechanism and the second limiting plate 5 are locked to ensure that the battery shell cover 6 is in the same position each time the battery shell cover is subsequently heat-sealed.

[0038] In general, the heat sealing tooling designed by the present invention can realize the precise positioning of the battery shell cover 6. After the first debugging is successful, it can realize rapid change of shape in the future without adjusting the position again. In addition, it also improves the efficiency and quality of the heat sealing of the battery shell cover 6 and reduces the production of defective products.

[0039] When the model needs to be changed, the mounting hole 103 provided on the mounting plate 1 is opened and the clamping rod inside is pulled out so that the entire cover lifting and positioning mechanism can be changed.

[0040] An upper heat-sealing plate 7 for heat-melting the battery shell cover 6 is provided below the bottom of the battery cover stopper 4. The upper heat-sealing plate 7 facilitates heat-melting the connection between the battery shell cover 6 and the battery shell, which is hooked by the cover-lifting hook 303. A lower heat-sealing plate 8 is provided at the bottom of the upper heat-sealing plate 7 for heat-sealing the battery shell after it has been precisely positioned on the assembly line. The upper heat-sealing plate 7 and the lower heat-sealing plate 8 are used in conjunction to facilitate heat-sealing the battery shell and the battery shell cover 6. A first heating element 701 for heat-melting the battery shell cover 6 is mounted at the top center of the upper heat-sealing plate 7. A second heating element 801 for heat-sealing the battery shell and the battery cover is mounted at the bottom center of the lower heat-sealing plate 8.

[0041] The battery cover stopper 4 is internally provided with a cover-lifting mechanism for lifting the battery shell cover 6. The cover-lifting mechanism includes a tilted top track 3, a cover-lifting cylinder 301, a mounting bracket 302, and a cover-lifting hook 303. The mounting bracket 302 is mounted on one end of the tilted top track 3. The cover-lifting cylinder 301 is fixed to one side of the mounting bracket 302. The output end of the cover-lifting cylinder 301 is fixedly connected to the cover-lifting hook 303 provided on the tilted top track 3. The cover-lifting hook 303 is slidably connected to a slide groove provided on the tilted top track 3. The bottom of the mounting bracket 302 is fixed to the top end of the battery cover stopper 4 by screws 501.

[0042] The present invention facilitates the hooking up of the battery shell cover 6 by arranging the inclined top track 3, the cover lifting cylinder 301, the mounting frame 302 and the cover lifting hook 303 so as to be heat-soldered by the upper heat sealing plate 7, thereby improving the uniformity of heat-soldered.

[0043] By opening the cylinder, the cover-lifting hook 303 moves obliquely upward along the inclined top track 3, and the cover-lifting hook 303 hooks the corresponding position of the battery shell cover 6 to lift the battery shell cover 6 so that the battery shell cover 6 is hooked and hung to pass through the first heating element on the upper heat sealing plate for heat melting.

[0044] A battery shell cover 6 for heat-melting the upper heat-sealing plate 7 is provided inside the battery cover limiting seat 4 , and the battery shell cover 6 is located on the top of the upper heat-sealing plate 7 .

[0045] The upper heat-sealing plate 7 is provided with a through-hole second bayonet hole 702, and the lower heat-sealing plate 8 is provided with a through-hole third bayonet hole 802. The second bayonet hole 702 and the third bayonet hole 802 correspond to each other and are secured together by a sealing bayonet. The upper heat-sealing plate 7 and the lower heat-sealing plate 8 are installed on the production line to improve the efficiency of the thermal connection between the battery shell and the battery shell cover 6.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
