DETAILED DESCRIPTION

[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0042] like Figures 1 to 4As shown, a feeding mechanism of an automatic sleeve labeling machine for cylindrical lithium batteries comprises a sleeve labeling platform 1 and a material box 2 arranged on the sleeve labeling platform 1 for loading battery sleeve labels. The width of the interior of the material box 2 corresponds to the length of the battery to avoid lateral deflection during the process of filling the battery into the material box 2, which causes the battery in the material box 2 to be blocked and affects the efficiency of loading the battery onto the sleeve labeling machine.

[0043] A support frame 6 is fixed on the labeling platform 1 .

[0044] The cylindrical lithium battery automatic sleeve labeling machine feeding mechanism also includes:

[0045] A conveying unit 7 is provided on the support frame 6 and is used for continuously loading batteries into the material box 2 .

[0046] The auxiliary bucket 9 is arranged between the material box 2 and the discharge end of the conveying part 7 , and the length of the top opening of the auxiliary bucket 9 is greater than half of the length of the top opening of the material box 2 .

[0047] The reciprocating driving part 8 is used to drive the auxiliary bucket 9 to reciprocate linearly. The length of the top opening of the auxiliary bucket 9 is designed to be greater than half of the length of the top opening of the material box 2, so that when the auxiliary bucket 9 moves reciprocatingly linearly on the top of the material box 2, the batteries can still fall from the discharge end of the conveying part 7 into the inside thereof, thereby achieving uniform spreading of the batteries in the material box 2, avoiding the accumulation of batteries on one side of the material box 2, which would affect the battery loading of the subsequent sleeve labeling machine.

[0048] The conveying unit 7 comprises:

[0049] The conveying frame 71 is fixed on the support frame 6, and the internal width of the conveying frame 71 corresponds to the length of the battery, which is beneficial for the battery to maintain its axial direction perpendicular to its conveying direction during the conveying process, so that it can maintain this state and be accurately filled into the material box 2, thereby realizing automatic and uniform filling of the batteries into the material box 2, thereby replacing manual filling of batteries into the material box 2, improving the efficiency and continuity of battery filling, and avoiding affecting the efficiency of the labeling machine for the battery.

[0050] A limiting slide 75 is fixed on the conveying frame 71 for maintaining the battery unloading posture, and the inner width of the limiting slide 75 corresponds to the diameter of the battery.

[0051] By designing the internal width of the limiting slide 75 to a size corresponding to the diameter of the battery, the battery can maintain a horizontally lying posture when falling, so that it can maintain a horizontally lying posture and fall into the auxiliary bucket 9, and accumulate from the auxiliary bucket 9 to maintain the original posture and fall into the material box 2, so that the battery can slide smoothly downward in the material box 2, avoiding the problem of battery blockage in the material box 2.

[0052] In this embodiment, the conveying unit 7 further includes:

[0053] The conveying rollers 73 disposed in the conveying frame 71 rotate relatively.

[0054] A conveyor belt 74 for conveying batteries is mounted on the two conveyor rollers 73 .

[0055] The servo motor 72 is used to drive one of the conveyor rollers 73 to rotate, and directly conveys the assembled batteries from the assembly line to the material box 2 through the conveyor belt 74, forming a coherent assembly line production and improving the overall efficiency of battery production.

[0056] In this embodiment, the lower opening of the limiting slide 75 is located above the middle of the material box 2, and the length of the limiting slide 75 corresponds to the length of the battery, and the distance between the arc-shaped end face of the conveying belt 74 and the end face in the conveying frame 71 is consistent with the width of the limiting slide 75, so that the battery can accurately fall into the limiting slide 75, and constrain the freedom of the battery inside it, so that the battery can only maintain a horizontally straight state and fall downward in the limiting slide 75, and cooperate with the auxiliary bucket 9 to make the battery maintain the above state and fall into the material box 2, avoiding the battery from deflecting in other directions and being difficult to fall into the material box 2, or deflecting in other directions when falling in the material box 2, causing the battery to get stuck in the material box 2.

[0057] In this embodiment, the auxiliary bucket 9 is an isosceles triangle, and the width inside the auxiliary bucket 9 is consistent with the width inside the limiting slide 75. Such a design can ensure that the batteries can always fall inside the auxiliary bucket 9 when it moves horizontally and linearly, and can smoothly slide along the inclined surface inside it into the material box 2, thereby improving the accuracy and filling efficiency of the batteries into the material box 2.

[0058] In this embodiment, the reciprocating drive unit 8 includes:

[0059] The reciprocating screws 83 disposed on the material box 2 rotate relative to each other, and the thread directions of the two reciprocating screws 83 are consistent.

[0060] A nut seat 85 is threadedly mounted on the reciprocating screw 83 and is used to support the linear movement of the auxiliary bucket 9.

[0061] A driving motor 81 is used to drive one of the reciprocating screws 83 to rotate.

[0062] Two transmission gears 82 are used for transmitting power between the driving motor 81 and one of the reciprocating screws 83 .

[0063] A transmission wheel 86 fixed on the reciprocating screw 83.

[0064] By starting the drive motor 81, the transmission belt 84 for synchronous linkage of the two transmission wheels 86 can drive one of the reciprocating screws 83 to rotate through the two transmission gears 82, and then drive the other reciprocating screw 83 to rotate synchronously in the same direction through the transmission wheel 86 and the transmission belt 84 at the other end of the reciprocating screw 83, and drive the two nut seats 85 to move synchronously in the same direction, so that the auxiliary bucket 9 carrying it can make reciprocating linear motion at the top of the material box 2 along the length direction of the material box 2, thereby achieving uniform spreading of the batteries in the material box 2.

[0065] In this embodiment, the cylindrical lithium battery automatic labeling machine feeding mechanism also includes:

[0066] A discharge port 3 is arranged at a bottom corner of one side of the material box 2 .

[0067] A side baffle 4 is fixed on the material box 2 and is used to cover the outer edge of the discharge port 3.

[0068] A telescopic rod 5 fixed on the material box 2 is used to push the batteries onto the labeling machine.

[0069] An inverted V-shaped box bottom 10 is provided in the material box 2 for separating the batteries.

[0070] By setting the inverted V-shaped box bottom 10, the batteries in the material box 2 can be divided into two sides thereof, so that the two discharge ports 3 can discharge the materials at the same time, and the batteries can be pushed out to the outside of the discharge port 3 along its axial direction by controlling the telescopic action of the telescopic rod 5, so that the batteries can be loaded onto the sleeve labeling machine in an orderly manner, and the side baffle 4 can be used to prevent the batteries from rolling and affecting the loading of the batteries onto the sleeve labeling machine, thereby improving the accuracy and stability of battery loading.

[0071] The above description is only the preferred embodiment of the utility model, and the parts not described in the utility model can be implemented by adopting or drawing on existing technologies. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. The changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the utility model should also fall within the protection scope of the utility model.
