Description

Technical Field

[0001] The invention relates to the technical field of battery preparation, and in particular to an intermediate switching device. Background Art

[0002] One end of the cylindrical battery is the positive electrode, and the other end is the negative electrode. To prevent short circuit, an insulating gasket needs to be attached to one end of the battery steel shell. The size of the insulating gasket needs to be close to the size of the battery steel shell opening so that the insulating gasket can fit inside the battery steel shell and ensure the insulation effect. Therefore, the cutting accuracy of the insulating gasket directly affects the quality of the battery.

[0003] The inventor of the present application has found in the long-term research and development that the current cutting of insulating gaskets is generally carried out in the following manner: Figure 1 The material roll is cut in a regular matrix form to facilitate the grabbing mechanism of the insulating gasket to grab. However, due to the limited width of the material roll, the distance D2 between adjacent insulating gaskets along the width direction of the material roll is smaller than the distance D1 along the length direction of the material roll. If D2 is too small, it cannot meet the cutting requirements of the insulating gasket, affecting the cutting effect. If the width of the material roll is increased, the utilization rate of the material roll will be reduced. Summary of the invention

The first transmission rod 460 rotates around the axial direction of the connecting rod 450 under the drive of the first driving member 410, driving the connecting rod 450 to rotate around its axial direction, thereby driving the second transmission rod 470 fixedly connected thereto to rotate around the axial direction of the connecting rod 450. The rotation of the second transmission rod 470 drives the end away from the connecting rod 450 and connected to the movable plate 420 to rotate, thereby causing the movable plate 420 to move toward the direction close to the substrate 100, and under the guidance of the first guide groove 431, drives the first adsorption member 200 to switch between the two workstations.

The first slide rail 511 extends along the first direction and can guide the movement of the first adsorption component 200 along the first direction, so that the movement of the first adsorption component 200 along the first direction is more stable.

[0045] See also Fig.10 In this embodiment, the intermediate shifting device 20 further includes a third mounting plate 540, which is connected to the first mounting plate 440. A second slide rail 110 is further provided on the base plate 100, and a second slider 120 is slidably provided on the second slide rail 110. The second slider 120 is connected to the third mounting plate 540. The second slide rail 110 extends along the second direction and can guide the movement of the first adsorption component 200 along the second direction, so that the movement of the first adsorption component 200 along the second direction is more stable.

[0046] In this embodiment, a first limiting member 130 is further provided on the substrate 100, and a limiting protrusion 541 is provided on the third mounting plate 540. The first limiting member 130 is used to cooperate with the limiting protrusion 541 or the limiting groove to limit the movement of the first adsorption member 200 along the second direction.

[0047] In this embodiment, the first limiting member 130 may be a limiting screw, which is disposed through the limiting member mounting plate 140 .

[0048] In this embodiment, the number of the first limiting members 130 is two, which are respectively disposed on the substrate 100 through the limiting member mounting plates 140, and can respectively limit the forward and reverse movements of the first adsorption member 200 along the second direction.

[0049] In other embodiments, a limiting groove may be further provided on the third mounting plate 540 , and the movement of the first adsorption component 200 along the second direction may be limited by the cooperation between the limiting groove and the first limiting component 130 .

[0050] See also Fig.11 In the present embodiment, a second driving member 600 and a third slide rail 150 are further provided on the substrate 100. The third slide rail 150 and the second slide rail 110 are located on opposite sides of the substrate 100. A third slider 160 is slidably provided on the third slide rail 150. The third slider 160 is respectively connected to the second driving member 600 and the second adsorption member 300 through the connecting plate 190. The second driving member 600 is used to drive the third slider 160 to drive the second adsorption member 300 to move along the second direction. The third slide rail 150 extends along the second direction, and can guide the movement of the second adsorption member 300 along the second direction, so that the movement of the second adsorption member 300 along the second direction is more stable.

[0051] In this embodiment, a second limit member 170 is further provided on the substrate 100. The second limit member 170 is provided on the substrate 100 through a limit member mounting plate 180. The second limit member 170 is used to abut against the third slider 160 to limit the movement of the second adsorption member 300 along the second direction.

[0052] In this embodiment, the second limiting member 170 may be a limiting screw, which is disposed through the limiting member mounting plate 180 .

[0053] See also Figure 3 In this embodiment, the second driving member 600 can drive the second adsorption member 300 to move from the third station marked by number 2 to the fourth station marked by number 4, so as to remove the scrapped insulating gasket 101.

[0054] Specifically, when it is necessary to obtain the insulating gasket 101, the first driving member 410 drives the first transmission rod 460 and the second transmission rod 470 to rotate, so as to drive the movable plate 420 to move along the first guide groove 431 of the limiting plate 430, thereby driving the first adsorption member 200 to move a first preset distance along the first direction first, and then move a second preset distance along the second direction, so that the first adsorption member 200 reaches the second station from the first station. At this time, the first adsorption member 200 and the second adsorption member 300 are staggered, which can be Figure 4 The insulating gasket 101 arranged in a staggered manner is adsorbed and fixed as shown; then the first drive 410 drives in the reverse direction, so that the first adsorption member 200 returns from the second station to the first station. At this time, the first adsorption member 200 and the second adsorption member 300 are arranged in parallel, so that when the first adsorption member 200 and the second adsorption member 300 place the insulating gasket 101 on the subsequent conveying device, the insulating gasket 101 is as shown. Figure 1 The side-by-side arrangement shown.

[0055] When the previous workstation detects that the insulating gasket 101 to be placed on the second adsorption component 300 is a defective product, the transfer mechanism such as the robot that transfers it from the previous workstation to the second adsorption component 300 is still operated in a pre-designed manner. The first adsorption component 200 moves from the first workstation to the second workstation, and the second driving component 600 drives the second adsorption component 300 to move from the third workstation to the fourth workstation, so that the insulating gasket 101 can fall from between the first adsorption component 200 and the second adsorption component 300 into the collection box below (not shown in the figure), thereby realizing the removal of waste.
