Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery glue sticking, in particular to a lithium battery tab glue sticking device. Background Art

[0002] Lithium batteries require multiple cells to be assembled into modules. In order to prevent short circuits and provide safety protection, insulating glue is usually applied to the place where the tabs contact the aluminum-plastic film.

[0003] At present, lithium batteries are usually glued manually after the sorting stage. Each battery needs to be glued on the positive and negative poles and the front and back positions, and a total of four glues are required. The manual speed is slow and laborious. At the same time, in the actual glue-sticking process, the battery cell is usually placed on the glue-sticking workbench manually, and the pole ear glue is manually cut. Moreover, the length of the pole ear glue is roughly judged by the naked eye, and then the prepared glue is manually affixed to the root of the battery cell pole ear, and the position of the glue is also judged by the naked eye to be in the center.

[0004] At present, since the glue application process is all done manually and by the naked eye, the length of each section of glue will be different, and it is impossible to achieve standardization, and the position of glue applied to the battery cell cannot be accurately positioned. At the same time, each battery cell needs to be applied with four layers of glue, and the efficiency of manual application is very slow. The battery cell is in a charged state, and manual application increases the risk of short circuit. Utility Model Content

[0061] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0062] Unless otherwise defined, the technical terms or scientific terms used in the present disclosure shall have the usual meanings understood by persons with ordinary skills in the field to which the present disclosure belongs.

In addition, the terms "first", "second", "third", "fourth", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0063] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0064] The following is a detailed description of a disposable intracranial targeted drug delivery sterile microcatheter according to an embodiment of the utility model in conjunction with the accompanying drawings:

[0065] See also Figures 1 to 9 It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the restrictive conditions for the implementation of the utility model, so they have no substantive technical significance. Any modification of the structure, change in the proportion relationship or adjustment of the size, without affecting the effect and purpose that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model.

[0066] See also Figure 1 The utility model discloses a gluing device for a lithium battery tab, which can be used to improve the problem that the manual gluing method is inefficient and has the risk of short circuit during the gluing process of the existing lithium battery tab glue. Specifically, the gluing device for the lithium battery tab may include a mounting frame 100, a positioning mechanism 200, a gluing mechanism 300 and a triggering mechanism. The battery cell 10 for attaching the tab glue is located on the positioning mechanism 200, and is subjected to gluing by the gluing mechanism 300. At the same time, the triggering mechanism is used to generate a gluing signal, and the gluing mechanism 300 performs gluing after receiving the gluing signal. In practical applications, the lithium battery may be a soft-pack lithium-ion battery.

[0067] Specifically, the mounting frame 100 includes a horizontal mounting substrate 110 and a vertical mounting substrate 120, and the horizontal mounting substrate 110 and the vertical mounting substrate 120 are vertically arranged. It can be understood that the positioning mechanism 200 is located on the horizontal mounting substrate 110, and the gluing mechanism 300 is located on the vertical mounting substrate 120. At the same time, a touch panel 500 is also allowed to be arranged on the vertical mounting substrate 120, and the touch panel 500 is communicatively connected to a controller. Therefore, the working state of the device in actual use can be adjusted by the touch panel 500, and the corresponding parameters can be adjusted.

[0068] See also Figures 1 to 3 In one embodiment, the battery cell 10 is connected to the positioning mechanism 200 in a liftable manner. Therefore, by making the battery cell 10 liftable, the applicability of the device in actual use can be improved to meet the glue requirements of the tabs of the battery cells 10 with different thicknesses.

[0069] Specifically, the positioning mechanism 200 may include a base plate 210, a positioning plate 240, and a lifting assembly for connecting the base plate 210 and the positioning plate 240. The base plate 210 is fixedly connected to the horizontal mounting substrate 110, and the positioning plate 240 is arranged parallel to the top of the base plate 210. At the same time, a fixed plate 250 and a movable plate 260 are fixedly connected to the positioning plate 240, and a gap area for clamping the battery cell 10 is arranged between the fixed plate 250 and the movable plate 260. It should be noted that the fixed plate 250 and the positioning plate 240 are fixedly connected, and the movable plate 260 and the positioning plate 240 are fixedly connected. However, the position of the movable plate 260 on the positioning plate 240 is adjustable, and the size of the gap area can be adjusted by adjusting the position of the movable plate 260. The size of the gap area can be adjusted to accommodate battery cells 10 of different widths. As Figure 6 As shown, one end of the bottom plate 210 is connected to a limiting plate 270, and during the gluing process of the battery cell 10, the end of the battery cell 10 is clamped with the limiting plate 270. By clamping the end of the battery cell 10 with the limiting plate 270, the gluing accuracy of the battery cell 10 during the gluing process is ensured.

[0070] Furthermore, the lifting assembly includes a plurality of guide rods 220 arranged in parallel, and a lifting screw 230. The lifting screw 230 is arranged in parallel with the guide rod 220. One end of the guide rod 220 is fixedly connected to the positioning plate 240, and the other end is fixedly connected to the base plate 210. The guide rod 220 is a telescopic rod so that the positioning plate 240 can move along the axial direction of the guide rod 220. One end of the lifting screw 230 is pivotally connected to the positioning plate 240, and the other end is penetrated through the base plate 210 and the horizontal mounting base plate 110, and the lifting screw 230 is threadedly connected to the base plate 210 and the horizontal mounting base plate 110. By rotating the lifting screw 230 to adjust the relative distance between the positioning plate 240 and the base plate 210, the height adjustment of the positioning plate 240 is achieved.

[0071] See also Figures 1 to 8 In one embodiment, the glue sticking mechanism 300 includes a connection block 310 that allows movement in two directions, namely, along the normal direction of the horizontal mounting substrate 110 and the normal direction of the vertical mounting substrate 120. A fixing member is provided on the connection block 310. The fixing member can be used to absorb the glue strip. In another embodiment, the fixing member is a suction cup 311. When the glue strip is absorbed by the suction cup 311, the position of the connection block 310 is adjusted so that the glue strip is attached to the tab of the battery cell 10.

[0072] In one embodiment, the gluing mechanism 300 also includes a first connecting frame 312 and a second connecting frame 314. The first connecting frame 312 is fixedly connected to the vertically mounted substrate 120, and a mobile frame 313 is slidably connected to the first connecting frame 312, and the moving direction of the mobile frame 313 is the normal direction of the vertically mounted substrate 120. The driving method between the mobile frame 313 and the first connecting frame 312 can be driven by a cylinder. In order to improve the stability of the moving process of the mobile frame 313 on the first connecting frame 312, a limiting structure can be set between the mobile frame 313 and the first connecting frame 312. For example, the limiting structure can be a slide rail structure. However, it is not limited to this, and the limiting structure can be determined according to actual needs.

[0073] The second connecting frame 314 is connected to the moving frame 313, and a second cylinder is fixedly connected to the second connecting frame 314. The connecting block 310 is fixedly connected to the piston rod of the second cylinder, and the moving direction of the piston rod of the second cylinder is the normal direction of the horizontal mounting substrate 110. Therefore, the second cylinder located on the second connecting frame 314 can realize the movement of the connecting block 310 along the normal direction of the horizontal mounting substrate 110.

[0074] It should be noted that, in one embodiment, in order to improve the actual practical effect of the device, the position between the mobile frame 313 and the second connecting frame 314 can be adjusted, and the adjustment method is along the normal direction of the horizontal mounting substrate 110. By setting the position between the mobile frame 313 and the second connecting frame 314 to be adjustable, the movement stroke of the connecting block 310 during use can be effectively adjusted. Therefore, it can meet the gluing requirements of battery cells 10 of different thicknesses.

[0075] See also Figures 1 to 8 In one embodiment, a glue feeding assembly is further included, and the glue feeding assembly includes a glue pressing mechanism and a cutter 322. The glue pressing mechanism is used to transfer the glue strip to be attached to the upper part of the battery cell and the lower part of the fixing member away from the cutter 322, and the cutter 322 is used to cut the glue strip when the glue pressing mechanism transfers the glue strip to a predetermined length.

[0076] Specifically, the glue pressing mechanism includes a first sliding block 320 and a second sliding block 330. The first sliding block 320 is slidably connected to the vertically mounted substrate 120, and a clamping hand 321 is provided on the first sliding block 320, and the clamping hand 321 can be used to clamp the rubber strip. At the same time, a cutter 322 is provided in front of the clamping hand 321, so that the rubber strip can be cut by the cutter 322. The second sliding block 330 is slidably connected to the vertically mounted substrate 120, and a lifting frame 331 is movably connected to the second sliding block 330, and a pressure rod 332 is fixedly connected to the lifting frame 331. Among them, one end of the rubber strip used for attachment is connected to the clamping hand 321, and the other end is clamped between the suction cup 311 and the pressure rod 332.

[0077] Furthermore, a guide rail 340 is fixedly connected to the vertical mounting substrate 120, and the first sliding block 320 and the second sliding block 330 are respectively slidably connected to the guide rail 340. The first sliding block 320 and the vertical mounting substrate 120 are driven by the first cylinder, and the first cylinder drives the first sliding block 320 to reciprocate along the guide rail 340. The second sliding block 330 and the vertical mounting substrate 120 are driven by a transverse screw 351. The transverse screw 351 is threadedly connected to the second sliding block 330, and the transverse screw 351 is rotatably connected to the vertical mounting substrate 120. Specifically, a side plate 350 is fixedly connected to the vertical mounting substrate 120, and one end of the transverse screw 351 is rotatably connected to the side plate 350. At the same time, a power source is also connected to the transverse screw 351, and the transverse screw 351 can be driven to rotate by the power source. For example, in some embodiments, the power source is a servo motor, and the main shaft of the servo motor is transmission-connected to the transverse screw 351 .

[0078] Specifically, in the actual glue feeding process of the glue feeding assembly, the first sliding block 320 carries the gripper 321 to feed glue to the left. Then the pressure rod 332 rises with the lifting frame 331 to the position of the suction cup 311 of the glue sticking mechanism 300, and presses the left side of the glue strip against the suction cup 311. Then, the gripper 321 is released, and the first sliding block 320 is moved to the right, and the glue strip of the required length is pulled out. Furthermore, the gripper 321 is closed, and the glue strip is cut by the cutter 322. Finally, the pressure rod 332 descends, and the glue sticking mechanism rises to bring out the glue strip, and the connecting block 310 is extended to the ready glue sticking position.

[0079] It should be noted that the battery cell 10 can be manually turned over or reversed to repeat the gluing operation until all the glue strips on the four sides of the base of the battery cell 10 are glued.

[0080] See also Figures 1 to 9 , in one embodiment, in order to achieve the stability of the device during the glue supply process. The device is also allowed to include a glue preparation mechanism 400. The glue preparation mechanism 400 includes a glue preparation disk 410, a guide roller 420, a movable roller 440 and a driving mechanism. The glue preparation disk 410 is rotatably connected to the vertical mounting substrate 120, and the rubber strip is wound on the glue preparation disk 410. There are two guide rollers 420, and the guide rollers 420 are rotatably connected to the vertical mounting substrate 120. The driving mechanism is a third cylinder, which is arranged between the two guide rollers 420 and is fixedly installed on the vertical mounting substrate 120 along the normal direction of the horizontal mounting substrate 110. The movable roller 440 is installed at the movable end of the driving mechanism. It should be noted that the first side of the rubber strip is wound on the two guide rollers 420, and the movable roller 440 is in contact with the second side of the rubber strip.

[0081] A slider 430 is slidably arranged on the vertical mounting base plate 120, and a movable roller 440 is rotatably connected to the slider 430. Meanwhile, the slider 430 is fixedly connected to the cylinder rod of the third cylinder so that the slider 430 is driven to slide by the third cylinder.

[0082] Therefore, before each rubber strip is pulled, the third cylinder will push the slider 430 to lengthen the surrounding rubber strip, making it easier for the first sliding block 320 to pull the rubber strip.

[0083] See also Figure 1 and Figure 4 In one embodiment, the trigger mechanism is electrically connected to a controller, and the controller can be used to adjust the working state of each component. At the same time, the trigger mechanism can be determined according to actual needs. For example, the trigger mechanism can be a photoelectric sensor, which is electrically connected to the controller, used to sense the battery cell 10 in place signal and send the in place signal to the controller, and under the control of the controller, the battery cell 10 is fully automatically glued.

[0084] Alternatively, in one embodiment, the trigger mechanism may be a foot-operated device 600 , which is electrically connected to the controller, and under the control of the foot-operated device 600 and the controller, semi-automatic gluing of the battery cell 10 is achieved.

[0085] In summary, the utility model discloses a gluing device for lithium battery tabs, which can effectively solve the problem of independent gluing of charged battery cells 10 to improve the actual gluing efficiency. At the same time, the accuracy of gluing and the qualified rate of gluing are also improved. Compared with manual gluing, the speed is significantly improved. At the same time, it can adapt to the gluing of different models of battery cells 10 and has good adaptability. Therefore, it can effectively improve the problem of low efficiency and short circuit risk in the process of gluing the tabs of existing lithium batteries.

[0086] Therefore, the utility model effectively overcomes some practical problems in the prior art and has high utilization value and use significance.

[0087] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be performed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0088] The above specific implementations do not constitute a limitation on the protection scope of the present utility model. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
