[0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996. Its safety, specific capacity, self-discharge rate and performance-price ratio are better than lithium ion batteries. Due to its own high technical requirements, only companies in a few countries are currently producing this type of lithium metal battery. Lithium batteries need to generally use battery caps in the production process, and the battery caps need to be coated with glue in their inner grooves before buckling the lithium battery so that they can be bonded and fixed inside the lithium battery.

[0003] The current lithium battery cap coating machine has the following problems:

[0004] 1. The glue injection efficiency of the current lithium battery cap glue coating machine is generally low, and it is not possible to continuously and accurately inject glue into the inside of the lithium battery cap.

[0005] 2. The current lithium battery cap glue coating machine cannot continuously inject glue into lithium battery caps with smaller diameters. Summary of the invention

DETAILED DESCRIPTION

[0025] 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 described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example

[0027] See also Figure 1-4The present invention provides the following technical solutions: a lithium battery cap gluing machine, comprising a feeding vibration plate 1, a feeding buffer groove 2 extending from the outlet end of the feeding vibration plate 1, a gluing station groove 3 fixed in parallel on one side of the horizontal plane of the feeding buffer groove 2, the tail end of the feeding buffer groove 2 and the head end of the gluing station groove 3 are connected, a pneumatic push rod 4 is fixedly installed on the other side of the horizontal plane of the tail end of the feeding buffer groove 2, the forward extension direction of the pneumatic push rod 4 points to the head end of the gluing station groove 3, and an intermittent pushing mechanism 5 is provided at the bottom end of the middle part of the gluing station groove 3, The shift fork at the top of the intermittent pushing mechanism 5 is engaged with the strip hole on the bottom surface of the gluing station slot 3, and a longitudinal moving pair 6 is fixedly installed on the other side of the middle of the gluing station slot 3, and a transverse moving pair 7 is movably engaged with the top of the longitudinal moving pair 6, and three glue injection heads 8 are vertically fixed on one side of the top of the transverse moving pair 7 through a bracket, and the bottom ends of the three glue injection heads 8 are directly opposite to the top surface of the gluing station slot 3, and a finished material conveyor belt 9 is vertically placed at the tail end of the gluing station slot 3, and the tail end of the gluing station slot 3 is connected to the head end of the finished material conveyor belt 9.

[0028] In this embodiment, the feeding vibration plate 1 transfers the lithium battery caps to the feeding buffer slot 2 by vibration, and keeps the open end of the lithium battery caps facing upward to prepare for glue injection, and then the six lithium battery caps arranged in a row are pushed by the pneumatic push rod 4 from the tail end of the feeding buffer slot 2 to the head end of the glue coating station slot 3. The six lithium battery caps at the head end of the glue coating station slot 3 are moved to the middle of the glue coating station slot 3 and remain stationary under the fork at the top of the intermittent pushing mechanism 5. At this time, the longitudinal moving pair 6 and the transverse moving pair 7 move simultaneously according to the set program. The three glue injection heads 8 are driven by the bracket to position in the horizontal direction, and then the positioning point is used as the starting point to perform circular motion along the inner side of the lithium battery cap. At the same time, the glue in the three glue injection heads 8 begins to spray out glue under the control of the spraying instruction. At this time, the sprayed glue will accumulate on the inner side of the lithium battery cap to form a glue circle, realizing the gluing process. After the gluing process is completed, the intermittent pushing mechanism 5 is activated again to push away the current six lithium battery caps, and then push in six new lithium battery caps to carry out the next glue injection process.

[0029] Specifically, a positioning cylinder 10 is provided on one side of the middle of the gluing station slot 3 , and a telescopic shaft of the positioning cylinder 10 is vertically connected to a serrated positioning plate 11 , and the serrations on the serrated positioning plate 11 engage and fix the edge of the lithium battery cap embedded in the gluing station slot 3 .

[0030] In this embodiment, the positioning cylinder 10 fixes the lithium battery cap in the gluing station slot 3 through the serrations on the serration positioning plate 11, performs reference positioning on it, and keeps it fixed during the glue injection process, so that the three glue injection heads 8 can accurately inject glue to the lithium battery cap in the current position.

[0031] Specifically, the longitudinal moving pair 6 and the transverse moving pair 7 are screw drive pairs or synchronous belt drive pairs.

[0032] In this embodiment, the screw drive pair or the synchronous belt drive pair has good positioning accuracy, and its positioning level can reach the millimeter level. Therefore, it can drive the three glue injection heads 8 to move in an arc along the edge of the inner side of the lithium battery cap, thereby spraying the glue evenly and accurately onto the inner side of the lithium battery cap.

[0033] Specifically, a glue pump 12 is fixed to the side of the feeding vibration plate 1 , and three solenoid valves 13 are provided at the top of the glue pump 12 . The glue pump 12 is connected to the three glue injection heads 8 through the three solenoid valves 13 .

[0034] In this embodiment, the glue pump 12 provides power for glue injection, and the three solenoid valves 13 respectively control the rate and time of glue injection by the glue injection head 8, so as to quantitatively inject glue to each lithium battery cap.

[0035] Specifically, an oven 14 is provided on the top of the tail end of the finished material conveyor belt 9 .

[0036] In this embodiment, the oven 14 is used to dry the glue on the lithium battery cap after injection, so that its viscosity meets the requirements of the lithium battery production process.

[0037] Specifically, the distance between the three glue injection heads 8 is twice the diameter of the lithium battery cap.

[0038] In this embodiment, because the diameter of the lithium battery cap is small, the two adjacent glue injection heads 8 cannot perform glue injection operations on the two adjacent lithium battery caps. The present invention adopts a staggered injection method. The first glue nozzle injects glue on the No. 1 and No. 2 lithium battery caps, the second glue nozzle injects glue on the No. 3 and No. 4 lithium battery caps, and the third glue nozzle injects glue on the No. 5 and No. 6 lithium battery caps. In this way, the glue injection operation can be efficiently realized.

[0039] Specifically, the intermittent pushing mechanism 5 adopts a rocker-arm intermittent mechanism.

[0040] In this embodiment, the rocker-type intermittent mechanism uses an electric motor as the motive force, and drives the shift fork to move horizontally and vertically at the same time through two sets of connecting rods, so as to push the lithium battery cap located in the glue coating station slot 3.

[0041] In this embodiment, the intermittent pushing mechanism 5, the longitudinal moving pair 6, the transverse moving pair 7 and the electromagnetic valve 13 are known technologies that have been disclosed and widely used in daily life.

[0042] The working principle and use process of the present invention are as follows: the feeding vibration plate 1 transfers the lithium battery cap to the feeding buffer slot 2 by vibration, and keeps the open end of the lithium battery cap facing upward to prepare for glue injection, and then the six lithium battery caps arranged in a row are pushed by the pneumatic push rod 4 from the tail end of the feeding buffer slot 2 to the head end of the glue coating station slot 3, and the six lithium battery caps located at the head end of the glue coating station slot 3 are moved to the middle part of the glue coating station slot 3 and remain stationary under the fork at the top of the intermittent pushing mechanism 5. At this time, the longitudinal moving pair 6 and the transverse moving pair 7 move simultaneously according to the set program, and drive the three glue injection heads 8 to position in the horizontal direction through the bracket, and then use the positioning point as the initial point to perform a circular motion along the inner side of the lithium battery cap. At the same time, the glue in the three glue injection heads 8 is sprayed Under the control of the instruction, glue starts to be sprayed. At this time, the sprayed glue will accumulate on the inner side of the lithium battery cap to form a glue circle, realizing the gluing process. After the gluing process is completed, the intermittent pushing mechanism 5 acts again to push away the current six lithium battery caps, and then pushes on six new lithium battery caps to carry out the next glue injection process. Because the diameter of the lithium battery cap is small, the two adjacent glue injection heads 8 cannot perform glue injection operations on the two adjacent lithium battery caps. The present invention adopts a staggered injection method. The first glue nozzle injects glue to the No. 1 and No. 2 lithium battery caps, the second glue nozzle injects glue to the No. 3 and No. 4 lithium battery caps, and the third glue nozzle injects glue to the No. 5 and No. 6 lithium battery caps. In this way, the glue injection operation can be efficiently realized.

[0043] Finally, it should be noted that the above are only preferred embodiments of the present invention and are 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 replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
