[0002] A power lithium battery is a lithium battery used to power electric vehicles. It is wrapped in an aluminum shell on the outside and has a battery cell and electrolyte inside. When producing the battery aluminum shell, it is usually necessary to set a bottom support sheet on the inner bottom of the battery aluminum shell, and this bottom support sheet needs to be glued together with the inner bottom of the battery aluminum shell. Since the battery aluminum shell is not large in size and has a narrow internal space, the prior art does not have equipment specifically for this process, and even with the existing equipment, it is difficult to place the hot melt adhesive and the bottom support sheet in the battery aluminum shell and hot-melt it. Therefore, for this process, manual cutting of the ear glue, manual loading and manual hot-melting are generally used. However, this method has high labor intensity for workers and low production efficiency, which is not conducive to production. Summary of the invention

[0004] In order to achieve the above-mentioned purpose, the present invention provides a battery aluminum shell bottom support sheet hot melt machine, including a bottom support sheet feeding device, a translation mechanism, a hot melt device and a tab glue cutting device, the tab glue cutting device and the bottom support sheet feeding device are arranged above the translation mechanism, and the translation mechanism moves the battery aluminum shell to the bottom of the tab glue cutting device, the bottom support sheet feeding device and the hot melt device in sequence.

[0005] Compared with the prior art, the present invention uses a translation mechanism to sequentially transport the battery aluminum shell to the tab glue cutting device, the bottom support sheet feeding device and the hot melt device, and then the tab glue strip is cut by the tab glue cutting device and placed on the inner bottom of the battery aluminum shell, and then the bottom support sheet is placed inside the battery aluminum shell and on the tab glue strip by the bottom support sheet feeding device, and then the tab glue strip is melted by the hot melt device to bond the battery aluminum shell and the bottom support sheet together.

By arranging the first platform and the second platform on the bracket and utilizing the first driving mechanism to drive the first platform to translate, the first platform can be brought close to the second platform. Therefore, when the tab rubber strip passes through the first platform and reaches the second platform, the push cylinder can be utilized to drive the second platform to press the tab rubber strip against the pressing block, and the first platform can return to its original position and then the cutting mechanism can be used to cut a certain length of the tab rubber strip.

Of course, the transfer mechanism can also be set between the output end of the translation mechanism 5 and the hot melt device 8 to transfer the battery aluminum shell 200 from the translation mechanism 5 to the hot melt device 8.

[0022] Please see again Figure 3 , Figure 4 and Figure 5The tab rubber cutting device 6 includes a bracket 61, a pressing block 62, a downward driving mechanism 63, a first platform 64, a second platform 65, a first driving mechanism 66, a cutting mechanism 67, a reel 68 and a push cylinder 630. The reel 68 is pivotally connected to the bracket 61, and the tab rubber strip 300 is wound on the reel 68. The first platform 64 is horizontally slidably arranged on the bracket 61; the second platform 65 is horizontally slidably arranged on the bracket 61 through a slide, and the first platform 64 and the second platform 65 are respectively located on the left and right sides of the bracket 61. The first platform 64 is provided with a material channel 641, and the tab rubber strip 300 passes through the material channel 641 and extends toward the second platform 65 after passing through several rollers; the first driving mechanism 66 is arranged on the bracket 61 and can drive the first platform 64 to translate and approach the second platform 65; a sensor 69 is also provided before the material channel 641 for sensing whether the tab rubber strip 300 enters the material channel 641. The push cylinder 630 is arranged on the slide of the bracket 61 and can push the second platform 65 to move up and down, so as to press the tab rubber strip 300 moved to the second platform 65 on the pressing block 62; the cutting mechanism 67 is arranged on the first platform 64 and can cut off the tab rubber strip 300 extending out of the material channel 641. The pressing block 62 is located above the first platform 64 and the second platform 65 and partially overlaps with the second platform 65, and the pressing block 62 slides up and down relative to the bracket 61. The downward pressing driving mechanism 63 is arranged on the bracket 61 and can drive the pressing block 62 to move downward to drive the tab rubber strip 300 to move downward; the downward pressing driving mechanism 63 is a cylinder. By setting the first platform 64 and the second platform 65 on the bracket 61, and using the first driving mechanism 66 to drive the first platform 64 to translate, the first platform 64 can be close to the second platform 65. Therefore, when the pole ear rubber strip 300 passes through the first platform 64 to reach the second platform 65, the pushing cylinder 630 can be used to drive the second platform 65 to press the pole ear rubber strip 300 against the pressing block 62, and the first platform 64 can return to its original position and then the cutting mechanism 67 can cut a certain length of the pole ear rubber strip 300. In this way, cutting can be performed continuously. The whole process is fully automatic, no manual operation is required, and the cutting efficiency is high.

[0023] The bottom surface of the pressing block 62 is provided with a suction nozzle, which is connected to a negative pressure source. The suction nozzle can suck the cut tab rubber strip 300, that is, prevent the tab rubber strip 300 from falling, and can also make the tab rubber strip 300 move with the pressing block 62, so that the tab rubber strip 300 is placed on the inner bottom of the battery aluminum shell 200 through the pressing block 62 and the downward driving mechanism 63.

[0024] For example Figure 3 As shown, the first driving mechanism 66 includes a first motor, a first gear and a first rack, the first motor is arranged on the bracket 61, the first rack is fixed to the first platform 64, and the first gear is connected to the output end of the first motor and meshes with the first rack. The tab rubber cutting device 6 also includes a second driving mechanism 610, which is arranged on the bracket 61 and can drive the second platform 65 to translate. The second driving mechanism 610 has the same structure as the first driving mechanism 66. The second driving mechanism 610 can be used to adjust the distance of the second platform 65 relative to the first platform 64 when necessary, so that the length of the cut tab rubber strip 300 can be adjusted to adapt to battery aluminum shells 200 of different sizes, thereby improving the applicability of the equipment.

[0025] like Figure 4 and Figure 5 As shown, the tab rubber cutting device 6 also includes a clamping mechanism 620, which is arranged on the first platform 64 to hold the tab rubber strip 300 extending out of the material channel 641. The clamping mechanism 620 includes a rotating arm 621 and a clamping cylinder 622, the rotating arm 621 is an L-shaped structure, the middle part of the rotating arm 621 is pivoted to the first platform 64 and is located at the outlet of the material channel 641, the clamping cylinder 622 is arranged on the first platform 64 and the output end can extend and push one end of the rotating arm 621, so that the other end of the rotating arm 621 rotates and is held in the material channel 641. The clamping mechanism 620 is provided to prevent the tab rubber strip 300 from being extended or shifted during the cutting process, so that the accurate length size can be cut.

[0026] For example Figure 3 As shown, the cutting mechanism 67 includes a cutting cylinder 671, a slider 672 and a cutter 673. The cutting cylinder 671 is arranged on the first platform 64, the slider 672 is slidably arranged on the first platform 64 and connected to the output end of the cutting cylinder 671, and the cutter 673 is fixed to the slider 672 and arranged at the outlet of the material channel 641.

[0027] comprehensive Figures 3 to 5 The working principle of the tab glue cutting device 6 of the present invention is described as follows:

[0028] At the beginning, the tab rubber strip 300 extends from the reel 68, passes through several rollers, and then extends through the material channel 641. At this time, the pressing cylinder 622 is started to push one end of the rotating arm 621, and the rotating arm 621 rotates and the other end swings into the material channel 641, thereby pressing the tab rubber strip 300 into the material channel 641. After that, the first motor is started, and the first platform 64 is driven to approach the second platform 65 through the gear and rack. When the first platform 64 reaches the other side of the second platform 65, the front end of the tab rubber strip 300 is located on the surface of the second platform 65. At this time, the pushing cylinder 630 pushes the second platform 65, so that the second platform 65 rises and presses the tab rubber strip 300 against the pressing block 62. Then, the pressing mechanism 620 is reset to release the tab rubber strip 300. The first driving mechanism 66 drives the first platform 64 away from the second platform 65 and returns to its original position. Afterwards, the clamping mechanism 620 clamps the tab rubber strip 300 again, and the cutting cylinder 671 starts and pushes the slider 672 to move upward, and the slider 672 drives the cutter 673 to move upward and then cuts off the tab rubber strip 300 at the outlet of the material channel. At the same time, the suction nozzle of the pressing block 62 sucks the cut tab rubber strip 300 through negative pressure, and then the second driving mechanism 610 drives the second platform 65 to move away from the pressing block 62, so that a channel is formed between the first platform 64 and the second platform 65 for the pressing block 62 to continue to move downward, and finally, the downward driving mechanism 63 drives the pressing block 62 to move downward to the inside of the battery aluminum shell 200, and by inputting positive pressure to the suction nozzle, the tab rubber strip 300 is placed on the inner bottom of the battery aluminum shell 200.

[0029] comprehensive Figure 1 to Figure 2 The working principle of the battery aluminum shell bottom support sheet hot melt machine 100 of the present invention is described as follows:

[0030] First, the feeding mechanism 1 feeds the battery aluminum shell 200 and conveys it to the side close to the dust removal device 2, and then the first linkage conveying mechanism 4 transfers the battery aluminum shell 200 to the dust removal device 2 for dust removal. After that, the first linkage conveying mechanism 4 sequentially transfers the battery aluminum shell 200 to the preheating positions of the three preheating devices 3 for preheating. In this process, since the first linkage conveying mechanism 4 is a five-link manipulator, the transfer from the feeding mechanism 1 to the dust removal device 2, from the dust removal device 2 to the preheating position of the preheating device 3, and from the preheating position to the next preheating position are carried out simultaneously to improve efficiency. After that, the battery aluminum shell 200 is transferred to the translation mechanism 5, and the translation mechanism 5 sequentially passes the battery aluminum shell 200 through the tab rubber strip 300 cutting device and the bottom support sheet feeding device 7, and the tab rubber strip 300 cutting device and the bottom support sheet feeding device 7 respectively carry out the tab rubber strip 300 and the bottom support sheet on the battery aluminum shell 200. Then, the battery aluminum shell 200 is transferred from the translation mechanism 5 to the hot melt device 8, and the second linkage transport mechanism 10 transfers the battery aluminum shell 200 from one hot melt position of the hot melt device 8 to another hot melt position, from the hot melt device 8 to the cooling device 9, and from the cooling device 9 to the unloading mechanism 110. The hot melt device 8 and the cooling device 9 respectively perform hot melt and cooling on the battery aluminum shell 200, and after the tab rubber strip 300 is melted, the bottom support sheet is adhered to the inner bottom of the battery aluminum shell 200, and solidified under the cooling of the cooling device 9; finally, the unloading mechanism 110 unloads the battery aluminum shell 200.

[0031] Compared with the prior art, the present invention utilizes the first linkage conveying mechanism 4, the translation mechanism 5 and the second linkage conveying mechanism 10 to sequentially convey the battery aluminum shell 200 to the dust removal device 2, the preheating device 3, the ear glue cutting device 6, the bottom support sheet feeding device 7, the hot melt device 8 and the cooling device 9, and the ear glue strip 300 is cut by the ear glue cutting device 6 and placed on the inner bottom of the battery aluminum shell 200, and then, the bottom support sheet is placed inside the battery aluminum shell 200 and on the ear glue strip 300 by the bottom support sheet feeding device 7, and then the ear glue strip 300 is melted by the hot melt device 8 to make the battery aluminum shell 200 and the bottom support sheet bonded together. The whole process is completed by mechanization without manual operation, and therefore has the advantages of high automation and high production efficiency.

[0032] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
