Description

Technical Field

[0001] The present application relates to the technical field of cap assembly, and in particular to an automatic assembly machine for power lithium battery caps. Background Art

[0002] The lithium battery cap is an important component of the lithium battery. As a safety valve, it keeps the lithium battery in a relatively closed state, thereby preventing the alkaline solution inside from spreading and penetrating outward. At the same time, it can also be used as the lead-out terminal of the positive and negative electrodes of the lithium battery for charging and discharging operations.

[0003] Among them, when assembling the cap of the lithium battery, it is mostly transferred to the end of the lithium battery by a robot suction cup and pressure welding is performed. However, when assembling the lithium battery, the robot suction cup requires a complete adsorption-movement-placement-movement action, and the entire action stroke is large, which leads to its low assembly efficiency for the lithium battery cap. In addition, due to the large action stroke of the robot suction cup, the action space required for assembling the lithium battery cap is large, which leads to high energy consumption in the large-scale mass production process, which invisibly increases the production and preparation cost of the lithium battery.

[0004] Therefore, there is an urgent need for an assembly device for lithium battery caps to solve the defects of the above-mentioned existing cap assembly machines during actual use. Summary of the invention

[0005] The present application proposes an automatic assembly machine for power lithium battery caps, which can perform continuous assembly operations on caps. The entire equipment occupies a small space and has a short motion stroke, so that its assembly efficiency for the caps is high but energy consumption is low, and the production and preparation cost of lithium batteries is low. It is used to solve the problem that when using a robot suction cup to assemble lithium batteries, a complete adsorption-movement-placement-movement action is required, and the entire motion stroke is large, which leads to its low assembly efficiency for lithium battery caps. In addition, because the motion stroke of the robot suction cup is large, the motion space required for assembling lithium battery caps is large, resulting in high energy consumption in large-scale mass production.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: an automatic assembly machine for power lithium battery caps, comprising an outer shell body, wherein three groups of material distribution components arranged in a circular array are provided in the middle of the outer surface of the outer shell body, and a driving motor is fixedly installed on the top of the outer surface of the outer shell body, and the output shaft of the driving motor is fixedly connected to a group of caps. At the same time, the three groups of material distribution components are connected by transmission belts, and the caps are stacked on the top of the inner cavity of the outer shell body, and the material distribution component includes a transmission connecting rod fixedly installed on the outer surface of the outer shell body through an ear seat, a material distribution table is fixedly sleeved in the middle of the outer surface of the transmission connecting rod, and an extrusion table is fixedly sleeved at the bottom of the outer surface of the transmission connecting rod, a second support plate with a fan-shaped structure is fixedly sleeved in the middle of one side of the outer surface of the extrusion table, and a spiral protrusion with the same rotation direction as the extrusion table is provided on the other side of the outer surface of the extrusion table.

[0007] Furthermore, a through slot is provided inside the outer shell body at a position corresponding to the material distribution assembly, so that the material distribution assembly and the structure thereon can extend into the inner cavity of the outer shell body.

[0008] Furthermore, the material distribution table includes a positioning plate fixedly mounted on the middle part of the outer surface of the outer shell body, and a first support plate with a fan-shaped structure is fixedly installed on the top of the positioning plate, and a pre-placement plate with a fan-shaped structure is fixedly installed on the bottom of the positioning plate. At the same time, the positions of the first support plate and the pre-placement plate are staggered.

[0009] Furthermore, the outer diameter of the positioning plate is smaller than the outer diameter of the first supporting plate or the pre-placement plate, and the edge of the positioning plate is located outside the inner wall of the outer shell.

[0010] Furthermore, the thickness of the positioning plate is equal to the thickness of the edge of the cap, thereby ensuring that during the rotation of the material distribution table and the structure thereon, one and only one cap can fall to the top of the pre-placement plate and be located between the first support plate and the pre-placement plate.

[0011] Furthermore, the end of the first support plate along its rotation direction is set to a beveled structure, and after the lowest cap falls, as the dividing table continues to rotate, the beveled structure of the first support plate can be stuck into the top of the lowest cap to provide support for the remaining caps in the inner cavity of the outer shell.

[0012] Furthermore, the inner diameter of the outer shell is the same as the outer diameter of the caps, so that when the material dividing assembly is actuated, the caps stacked in the outer shell can be separated one by one from the bottom thereof without being easily shaken.

[0013] The present invention application has the following technical effects:

[0014] The present application provides an automatic assembly machine for power lithium battery caps. For the arrangement of the outer shell and the structure thereon, the rotating action of the dividing table on the dividing assembly can be used to individually separate the caps stacked in the outer shell from the bottom, and then the individually separated caps can be pressed onto the ends of the lithium batteries using the extrusion table and the structure thereon. In addition, a continuous assembly action of the caps is formed during the continuous rotation of the dividing assembly. The entire device occupies a small space and has a short action stroke, which improves the assembly efficiency of the lithium battery caps but reduces energy consumption.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] like Figure 1 , Figure 3As shown, an automatic assembly machine for power lithium battery caps comprises an outer shell 1 fixedly mounted on the lithium battery cap assembly machine by bolts, and the outer shell 1 is located directly above the lithium battery conveying device, and three groups of material distribution components 2 arranged in a circular array are provided in the middle of the outer surface of the outer shell 1, and a driving motor 4 is fixedly mounted on the top of the outer surface of the outer shell 1, and the output shaft of the driving motor 4 is fixedly connected to a group of caps 3, and at the same time, the three groups of material distribution components 2 are connected by a transmission belt 5, and then when the driving motor 4 is started, the three groups of material distribution components 2 can be synchronously driven to rotate under the transmission action of the transmission belt 5, and a plurality of groups of caps 3 are stacked on the top of the inner cavity of the outer shell 1, and the caps 3 are split, squeezed and assembled to the ends of the lithium batteries one by one during the rotation of the material distribution component 2;

[0025] like Figure 2 , Figure 4 As shown, the material distribution component 2 includes a transmission connecting rod 6 fixedly mounted on the outer surface of the outer shell body 1 through an ear seat, and a material distribution platform 7 is fixedly sleeved in the middle of the outer surface of the transmission connecting rod 6, so that the caps 3 stacked at the bottom can be disassembled and transported downward during each rotation of the material distribution platform 7, and an extrusion platform 10 is fixedly sleeved at the bottom of the outer surface of the transmission connecting rod 6, and a second support plate 11 with a fan-shaped structure is fixedly sleeved in the middle of one side of the outer surface of the extrusion platform 10, and a spiral protrusion 12 which can be used to extrude the caps 3 downward and has the same rotation direction as the extrusion platform 10 is provided on the other side of the outer surface of the extrusion platform 10;

[0026] When the cap 3 transported from the distributing table 7 is caught by the second supporting plate 11, as the extrusion table 10 and the structure thereon rotate, the second supporting plate 11 no longer supports the transported cap 3 and it falls on the end of the lithium battery, and as the spiral protrusion 12 rotates, the cap 3 that falls on the end of the lithium battery can be squeezed downward, and then pressed onto the end of the lithium battery.

[0027] like Figure 2 As shown, in the present technical solution, a through groove is provided inside the outer shell 1 and at a position corresponding to the material dividing component 2, so that the material dividing component 2 and the structure thereon can extend into the inner cavity of the outer shell 1, and during its rotation, a corresponding supporting action is formed for the stacked caps 3 on the outer shell 1.

[0028] like Figure 4 , Figure 5As shown, in the present technical solution, the material distribution table 7 includes a positioning plate fixedly sleeved on the middle part of the outer surface of the outer shell body 1, and a first support plate 8 with a fan-shaped structure and extending into the inner cavity of the outer shell body 1 is fixedly installed on the top of the positioning plate, and a pre-release plate 9 with a fan-shaped structure and extending into the inner cavity of the outer shell body 1 is fixedly installed on the bottom of the positioning plate. At the same time, the positions of the first support plate 8 and the pre-release plate 9 are staggered with each other, and then during the rotation process, the cap 3 located at the bottom can fall from the top of the first support plate 8 to the top of the pre-release plate 9 under the action of gravity.

[0029] like Figure 5 As shown, in the present technical solution, the outer diameter of the positioning plate is smaller than the outer diameter of the first support plate 8 or the pre-placement plate 9, and its edge is located on the outside of the inner wall of the outer shell 1, so that when the distribution table 7 and the structure thereon rotate, there will be no mutual reflection between the cap 3.

[0030] like Figure 5 As shown, in the present technical solution, the thickness of the positioning plate is equal to the thickness of the edge of the cap 3, thereby ensuring that during the rotation of the distribution table 7 and the structure thereon, one and only one cap 3 can fall to the top of the pre-placement plate 9 and be located between the first support plate 8 and the pre-placement plate 9.

[0031] like Figure 4 As shown, in the present technical solution, the end of the first support plate 8 along its rotation direction is set as a bevel-shaped structure, and after the lowest cap 3 falls, as the dividing table 7 continues to rotate, the bevel-shaped structure of the first support plate 8 can be stuck into the top of the lowest cap 3 to support the remaining caps 3 in the inner cavity of the outer shell body 1, so that the caps 3 stacked in the inner cavity of the outer shell body 1 form an intermittent splitting operation.

[0032] like Figure 2 As shown, in the present technical solution, the inner diameter of the outer shell 1 is the same as the outer diameter of the cap 3, so when the dividing component 2 is actuated, the caps 3 stacked in the outer shell 1 can be separated one by one from the bottom without shaking, and the stability and reliability are high.
