During the diaphragm recovery process, the pole piece with the diaphragm is placed on the mounting frame 1, and the adsorption component 21 moves downward to be adsorbed onto the diaphragm, and moves upward to separate the diaphragm from the pole piece, so that the entire diaphragm is in a lifted and suspended state, and the diaphragm is wound up by the winding component to complete the diaphragm recovery, realize the fully automatic separation of the diaphragm and the pole piece, and perform automatic recovery of the diaphragm, with higher recovery efficiency, and can be directly arranged on the recovery production line to disassemble the diaphragm during the transmission of the pole piece.

[0036] Further, in this embodiment, the adsorption assembly further includes a bearing plate 22, which is movably mounted on the mounting frame 1 in the up-down direction, and the adsorption member 21 is fixedly mounted on the bearing plate 22.

[0038] Specifically, in this embodiment, the first driving member is a driving cylinder.

[0039] It should be noted that there are many implementations of the adsorption member 21, as long as the diaphragm can be separated from the electrode piece. For example, an adhesive plate can be used to adsorb the diaphragm by adhesive.

[0040] Specifically, in this embodiment, the adsorption member 21 includes a membrane suction cup, so as to facilitate long-term and multiple adsorption of the membrane.

[0041] In addition, in this embodiment, a plurality of adsorbents 21 may be provided to facilitate adsorption of the diaphragm according to different situations.

In this embodiment, when the diaphragm is actually separated, it may be in the middle position of the assembly line, and there is no contact with the diaphragm in the pole piece. Therefore, the diaphragm may be lifted in the middle position, and both ends are drooped to the pole piece, which is difficult to be directly rolled up by the winding assembly. Therefore, it is necessary to cut the diaphragm before rolling up, so that only the adsorbed part of the diaphragm is torn apart. When rolling up, this part can be used as the starting point for rolling up, which is convenient for continuous rolling backwards and the operation of the winding device.

[0043] It should be noted that there are many ways to set the cutting member 31, for example, the diaphragm is cut directly by a cutting blade.

[0046] There are multiple implementations of the second driving member. In this embodiment, the second driving member is also a driving cylinder.

[0047] On the other hand, the winding assembly has a variety of implementations, such as directly using a winding roller to wind up, lifting the diaphragm, placing it on the winding roller, and winding up the diaphragm by rotating the winding roller.

[0048] In the upper diaphragm recovery device 100 provided by the utility model, the winding assembly includes a winding frame 41 and a plurality of winding rods 42; in this embodiment, the number of the winding rods is 2. The winding frame 41 is rotatably mounted on the mounting frame 1 around a horizontal axis; the two winding rods 42 are both arranged to extend in the horizontal direction, and the two winding rods 42 are installed on the winding frame 41 at intervals, and the two winding rods 42 are used to wind up the upper diaphragm together. In this embodiment, the diaphragm is wound by the two winding rods 42 arranged at intervals, and the two winding rods 42 are wound around each other by the rotation of the winding frame 41, so that the diaphragm between the two winding rods 42 can be easily self-wound, and there is no need to manually continue to fix the diaphragm on the winding assembly, and the winding efficiency is high.

[0049] It should be noted that the winding assembly further includes a third driving member for driving the winding frame 41 to rotate.

[0050] Specifically, in this embodiment, the third driving member is a driving motor.

[0051] On the other hand, in the upper diaphragm recovery device 100 provided by the present invention, please refer to Figure 3 , the winding assembly is movably mounted on the mounting frame 1 in the horizontal direction.

In this embodiment, the horizontal displacement control of the winding assembly is performed by means of the slide groove and the slide rail, which can ensure that the winding assembly is displaced to the correct position and the stability during the displacement process can be ensured.

[0053] It should be noted that, in this embodiment, the upper diaphragm recovery device 100 further includes a fourth driving member, and the fourth driving member drives the winding assembly to move in a horizontal direction.

[0054] There are multiple implementations of the fourth driving member. In this embodiment, the fourth driving member is a driving hydraulic cylinder.

In this embodiment, in order to facilitate the winding of the winding assembly, after the adsorption member attaches and lifts the upper diaphragm on the pole piece upward, the diaphragm is clamped by the clamping member 61, at which time the adsorption member can be released, and then the winding assembly starts to wind, and the diaphragm is released after the initial winding is completed, so as to ensure the reliability of the winding of the diaphragm.

[0057] It should be noted that the clamping member 61 has multiple implementations. In this embodiment, the clamping member 61 is a clamping claw.

[0058] Based on the above-mentioned upper diaphragm recovery device 100 , the present invention provides a specific embodiment.

[0059] In this embodiment, the adsorption member moves downward to absorb the upper diaphragm, and then moves upward to pull the upper diaphragm upward to separate from the pole piece;

[0061] Then, the adsorption member drives the upper diaphragm to continue to move upward, and the cutting member in the cutting assembly moves at the same time to cut off the lifted upper diaphragm. At this time, only one end of the upper diaphragm still adhered to the electrode is adsorbed on the adsorption member, and the other end of the upper diaphragm is cut off and falls off;

[0062] After the upper diaphragm is lifted up to the specified position, the winding assembly moves toward the adsorption assembly, and at the same time, the winding frame starts to rotate, and the upper diaphragm is wound around by multiple winding rods to start winding;

[0063] After the upper diaphragm is rolled up, the winding assembly moves away from the adsorption assembly to remove the diaphragm on the winding rod.
