[0020] Unless otherwise defined, all professional terms used below have the same meanings as those generally understood by those skilled in the art. The professional terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the scope of protection of the present utility model. Example

[0021] like Figure 1 The illustrated embodiment of a casing machine electrode reverse material removal device 4 comprises a turntable 1, a transfer clamp 2, a polarity detection device 3, and a material removal device 4; a plurality of transfer clamps 5 are arranged on the outer edge of the turntable 1; the transfer clamp 2 is arranged on one side of the turntable 1, and a clamping member 28 of the transfer clamp 2 is arranged above a working position of the turntable 1. Figure 1-Figure 3 As shown, the material return device 4 includes a material return trough 41, a push rod 42 and a push block (not shown in the figure); the push rod 42 is located below the drive assembly 25 of the transfer clamp 2, the push block is located on one side of the bottom end of the push rod 42 and is in contact with or hinged to the push rod 42, and the lower part of the push rod 42 is connected to the frame 6 through a rotating shaft; the material return trough 41 is located below the working position corresponding to the clamping member 28.

[0022] In this embodiment, the transfer clamp 2 includes a clamping member 28, a first clamping jaw 21, a second clamping jaw 22, a clamping jaw reset spring 23, a connecting rod 24, a driving assembly 25 and a shifting assembly 26; the first clamping jaw 21 and the second clamping jaw 22 are arranged on the shifting assembly 26 through a connecting shaft; the first clamping jaw 21 and the second clamping jaw 22 are both connected with a clamping member 28, the middle parts of the first clamping jaw 21 and the second clamping jaw 22 are meshed and connected by a tooth portion 27, and a clamping jaw reset spring 23 is connected between the first clamping jaw 21 and the second clamping jaw 22; the connecting rod 24 is arranged on the other end of the first clamping jaw 21 or the second clamping jaw 22 opposite to the clamping member 28; the driving assembly 25 is connected to the connecting rod 24.

[0023] In this embodiment, the driving assembly 25 includes a bearing 251, a top block 252, a rocking rod 253 and a driving rod 254; the top end of the driving rod 254 is connected to the middle part of the rocking rod 253, and the bottom end is connected to the cam (not shown in the figure); the bearing 251 is connected to the connecting rod 24, the top block 252 is connected to one end of the rocking rod 253 and is arranged opposite to the bearing 251, and the end of the rocking rod 253 connected to the top block 252 is connected to the frame 6 through a rotating shaft. The top rod 42 is arranged below the other end of the rocking rod 253 opposite to the top block 252. In this embodiment, the transfer clamp 2 transfers the aluminum electrolytic capacitor from the main body clamping portion 51 of the mobile clamp to the lead clamping portion 52. When the transfer clamp 5 moves to the working position of the transfer clamp 2, under the movement of the cam, the driving rod 254 pushes the rocker arm 253 upward, so that the top block 252 on the rocker arm 253 pushes the bearing 251 on the connecting rod 24, so that the transfer clamp 2 opens; under the movement of the cam, when the driving rod 254 swings the rocker arm 253 downward, the top block 252 is reset, so that the top block 252 is disengaged from the bearing 251, and under the action of the clamping claw reset spring 23, the transfer clamp 2 clamps the aluminum electrolytic capacitor; and it shifts under the action of the shifting component 26.

[0024] In this embodiment, the shift assembly 26 includes a connecting block 261, a connecting rod 262, a connecting frame 263 and a connecting rod reset spring 264. The connecting rod 262 is arranged on the connecting frame 263, and the connecting rod 262 moves forward and backward on the connecting frame 263. The connecting rod reset spring 264 is connected between the end of the connecting rod 262 and the connecting frame 263; the head end of the connecting rod 262 is connected to the connecting block 261; the first clamping claw 21 and the second clamping claw 22 are arranged on the connecting block 261 through a connecting shaft. In this embodiment, since the transfer clamp 2 needs to clamp the aluminum electrolytic capacitor horizontally, the transfer clamp 2 can only move downward from the top to clamp the aluminum electrolytic capacitor, but cannot clamp it horizontally. In order to enable the transfer clamp 2 to move downward from the top to clamp the aluminum electrolytic capacitor on the transfer clamp 5, the connecting rod 262 is arranged at an angle on the connecting frame 263, so that the connecting rod 262 drives the connecting block 261 to move obliquely, so that the transfer clamp 2 on the connecting block 261 can move from top to bottom to clamp the aluminum electrolytic capacitor on the transfer clamp 5.

[0025] In this embodiment, each transfer clamp 5 on the turntable 1 corresponds to a work position, and each time the turntable 1 moves inching, the transfer clamp 5 moves to the next work position. In this embodiment, the polarity detection device 3 is located at the previous work position of the transfer clamp 2; when the polarity detection device 3 detects that the anode guide pin and the cathode guide pin of the aluminum electrolytic capacitor on the moving clamp are reversed or the anode guide pin or the cathode guide pin is bent, the corresponding aluminum electrolytic capacitor is removed at this work position of the transfer clamp 2.

[0026] like Figure 3 As shown, when the aluminum electrolytic capacitor on the transfer clamp 5 needs to be removed, when the transfer clamp 2 transfers the aluminum electrolytic capacitor from the main body clamping portion 51 of the mobile clamp to the lead clamping portion 52, the push block at the bottom end of the push rod 42 pushes the push rod 42 so that the upper end of the push rod 42 presses against one end of the swing rod 253 so that the top block 252 at the other end of the swing rod 253 presses against the bearing 251 on the connecting rod 24, so that the transfer clamp 2 is in an open state. When the transfer clamp 2 clamps the aluminum electrolytic capacitor on the main body clamping portion 51 of the transfer clamp 5, since the transfer clamp 2 is in an open state, when the transfer clamp 5 is opened, the aluminum electrolytic capacitor on the main body clamping portion 51 of the transfer clamp 5 falls into the material return trough 41, thereby completing the removal of the aluminum electrolytic capacitor with reverse polarity or bent anode guide pins or cathode guide pins.

[0027] In this embodiment, in order to ensure that the position of the push rod 42 is consistent each time it moves, so as to support one end of the swing rod 253; a limit block 43 is set on the frame 6 on one side of the push rod 42; when the push rod 42 moves to the position of the limit block 43, the upper end of the push rod 42 just supports one end of the swing rod 253.

[0028] In this embodiment, the polarity detection device 3 includes an isolation block 31, a detection sheet 32, a V-shaped connector 33, a pressure block 34 and a pressure detector 35; the detection sheet 32 ​​is connected to one end of the V-shaped connector 33, and the pressure block 34 is connected to the other end of the V-shaped connector 33; the middle part of the V-shaped connector 33 is connected to the rotating shaft, and a rotating shaft reset spring (not shown in the figure) is arranged on the rotating shaft; the detection sheet 32 ​​is arranged on one side of the isolation block 31; and the pressure detector 35 is arranged directly below the pressure block 34. In this embodiment, a detection through hole 311 is arranged on the isolation block 31, and the detection sheet 32 ​​is located on one side of the detection through hole 311, and the length of the detection part on the detection sheet 32 ​​is less than the length of the detection through hole 311.

[0029] In this embodiment, before removing the aluminum electrolytic capacitors with the anode guide pin and the cathode guide pin reversed or with the anode guide pin or the cathode guide pin bent, it is necessary to first detect whether the anode guide pin and the cathode guide pin of the aluminum electrolytic capacitor are reversed or whether they are bent. In this embodiment, the detection of whether the anode guide pin and the cathode guide pin of the aluminum electrolytic capacitor are reversed or whether they are bent is completed by two polarity detection devices 3. The two polarity detection devices 3 are symmetrically arranged; the detection sheets 32 of the two polarity detection devices 3 are arranged up and down; the detection sheet 32 ​​for detecting the anode guide pin is at the bottom, and the detection sheet 32 ​​for detecting the cathode guide pin is at the top. During the detection, under the action of the shaft reset spring, the detection sheet 32 ​​moves toward the detection through hole 311. When there is an anode guide needle or a cathode guide needle, the detection sheet 32 ​​will be blocked by the anode guide needle or the cathode guide needle and cannot continue to move. At this time, the pressure block 34 on the V-shaped connector 33 will not apply pressure to the pressure detector 35; when the anode guide needle and the cathode guide needle are reversed or the anode guide needle or the cathode guide needle is bent, at least one detection sheet 32 ​​will be blocked by the anode guide needle or the cathode guide needle and enter the detection through hole 311. At this time, the pressure block 34 on the V-shaped connector 33 will apply pressure to the pressure detector 35, thereby detecting it. When the pressure detector 35 detects pressure, the current aluminum electrolytic capacitor is removed from the working position of the transfer clamp 5. In this embodiment, in order to ensure the normal operation of the polarity detection device 3, the elastic coefficient of the rotating shaft reset spring should not be too large. It is necessary to ensure that the detection piece 32 hitting the anode guide needle or the cathode guide needle will not cause the anode guide needle or the cathode guide needle to deform. At the same time, in the absence of the anode guide needle or the cathode guide needle blocking it, the detection piece 32 can enter the detection through hole 311.

[0030] In the utility model, the aluminum electrolytic capacitor with reversed electrodes can be removed without stopping the rotary table, thereby improving the working efficiency of the casing machine.
