[0037] The main support 1;

[0038] Servo motor 2, bolted to the main support 1;

[0039] Detector 21, bolted to the lower part of the main support 1;

[0040] Support plate 3, rotatingly connected to the middle part of the main support 1, the output shaft of the servo motor 2 is fixedly connected with the support plate 3;

[0041] Feeding plate 4, riveted to the upper part of the main support 1;

[0042] Discharge plate 5, riveted to the lower part of the main support 1;

[0043] Defective product inclined plate 6, riveted to the lower part of the main support 1;

[0044] Clamping assembly, provided on the support plate 3, for clamping the sheet capacitor;

[0045] Extrusion assembly, provided on the main support 1, for assisting in clamping the sheet capacitor;

[0046] Auxiliary detection assembly, provided on the extrusion assembly, for assisting in detecting the sheet capacitor.

[0047] The clamping assembly comprises: a plurality of placement frames 71 welded on the support plate 3; each placement frame 71 is welded with a guide frame 72; each placement frame 71 is slidingly connected with two end face clamping frames 73; each end face clamping frame 73 and the placement frame 71 are connected with a reset spring 74 through a hook; the inner side of each placement frame 71 is slidingly connected with two side edge clamping frames 75; each side edge clamping frame 75 is welded with a clamping rod 751; one of the end face clamping frames 73 on each placement frame 71 is slidingly connected with an extrusion frame 76; the extrusion frame 76 and the end face clamping frame 73 are connected with an extrusion spring 77 through a hook.

[0048] The extrusion assembly comprises: two support frames 81 welded on the middle part of the main support 1; the two support frames 81 are slidingly connected with an arc-shaped frame 82; the two support frames 81 are threadedly connected with an adjusting screw 83, and the arc-shaped frame 82 is rotatingly connected with the adjusting screw 83.

[0049] The auxiliary detection assembly comprises: a conductive copper frame 91 welded on each end face clamping frame 73 connected with the extruding frame 76; a contact frame 92 slidingly connected on each arc-shaped frame 82, and a groove is formed on each arc-shaped frame 82, and the two contact frames 92 are connected with the positive and negative electrodes of the detector 21 through an electric circuit; two spiral springs 93 are connected between the contact frame 92 and the arc-shaped frame 82 through hooks; and two electromagnets 94 are connected on each arc-shaped frame 82 through bolts, the electromagnets 94 are located on the inner side of the spiral springs 93, and the electromagnets 94 are connected with the detector 21 through an electric circuit.

[0050] At the beginning, the staff starts the servo motor 2, the detector 21 and the electromagnet 94. The electromagnet 94 generates magnetic force after being electrified. The electromagnet 94 magnetically attracts the contact frame 92 to move, and the spiral spring 93 is compressed. The contact frame 92 is in contact with one side of the electromagnet 94, so that the side of the contact frame 92 close to the support disc 3 is flush with the side of the arc-shaped frame 82 close to the support disc 3. The output shaft of the servo motor 2 intermittently reverses to drive the support disc 3, the placement frame 71, the guide frame 72, the end face clamping frame 73, the reset spring 74, the side edge clamping frame 75, the clamping rod 751, the extrusion frame 76, the extrusion spring 77 and the conductive copper frame 91 to reverse. Then the staff intermittently places the chip capacitor on the feeding plate 4. The chip capacitor falls into one of the placement frames 71 under the action of its own gravity along the feeding plate 4. Then the output shaft of the servo motor 2 rotates to drive the support disc 3, the placement frame 71, the guide frame 72, the end face clamping frame 73, the reset spring 74, the side edge clamping frame 75, the clamping rod 751, the extrusion frame 76, the extrusion spring 77 and the conductive copper frame 91 to rotate by a certain angle. The staff places the next chip capacitor on the feeding plate 4, and the next chip capacitor falls into the next placement frame 71. In this way, the chip capacitor is placed into the placement frame 71 at a time. The output shaft of the servo motor 2 drives the support disc 3, the placement frame 71, the guide frame 72, the end face clamping frame 73, the reset spring 74, the side edge clamping frame 75, the clamping rod 751, the extrusion frame 76, the extrusion spring 77 and the conductive copper frame 91 to reverse. The arc-shaped frame 82 extrudes the end face clamping frame 73 and the conductive copper frame 91 to move, so that the two end face clamping frames 73 move towards each other. One of the end face clamping frames 73 drives the extrusion frame 76 to move, and the movement of the extrusion frame 76 drives the clamping rod 751 and the side edge clamping frame 75 to move, so that the two side edge clamping frames 75 move towards each other. Then the two sides of the side edge clamping frame 75 are in contact with the two sides of the chip capacitor, respectively. Then the two end face clamping frames 73 move towards each other and are in contact with the two ends of the chip capacitor, respectively. In this way, the side edge clamping frame 75 and the end face clamping frame 73 clamp the chip capacitor together, so that the chip capacitor is clamped continuously and efficiently, which is convenient for subsequent detection of the chip capacitor. Then the output shaft of the servo motor 2 continues to drive the support disc 3, the placement frame 71, the guide frame 72, the end face clamping frame 73, the reset spring 74, the side edge clamping frame 75, the clamping rod 751, the extrusion frame 76, the extrusion spring 77 and the conductive copper frame 91 to reverse. The two end face clamping frames 73 are in contact with the two contact frames 92, respectively. The two conductive copper frames 91 are in contact with the two contact frames 92, respectively. The two ends of the chip capacitor are in communication with the positive and negative electrodes of the detector 21 through the conductive effect of the conductive copper frames 91 and the contact frames 92. The detector 21 detects the capacitance of the chip capacitor. When the detector 21 detects that the capacitance of the chip capacitor is unqualified, the detector 21 controls the electromagnet 94 to be closed for a short time. The electromagnet 94 no longer magnetically attracts the contact frame 92. The spiral spring 93 rebounds and elongates to drive the contact frame 92 to move reversely and reset.The contact frame 92 is no longer in contact with the end face clamping frame 73, and then the spiral spring 93 rebounds and stretches to drive the end face clamping frame 73 to move reversely and reset. The end face clamping frame 73 drives the extrusion frame 76 to move reversely and reset. The side clamping frame 75 and the end face clamping frame 73 no longer clamp the unqualified chip capacitors. The unqualified chip capacitors fall onto the defective product inclined plate 6, and then fall downward along the defective product inclined plate 6. Then the electromagnet 94 re-magnetically attracts the contact frame 92. The contact frame 92 re-presses the end face clamping frame 73. Workers collect the unqualified chip capacitors. When the detector 21 detects that the capacitance of the chip capacitor is qualified, the detector 21 will not control the electromagnet 94 to be closed. Then the output shaft of the servo motor 2 continues to drive the support disc 3, the placement frame 71, the guide frame 72, the end face clamping frame 73, the reset spring 74, the side clamping frame 75, the clamping rod 751, the extrusion frame 76, the extrusion spring 77 and the conductive copper frame 91 to reverse. The end face clamping frame 73 and the side clamping frame 75 keep clamping the chip capacitors. Then the end face clamping frame 73 is separated from the arc-shaped frame 82. The spiral spring 93 rebounds and stretches to drive the end face clamping frame 73 to move reversely and reset. The qualified chip capacitors fall on the discharge plate 5. The qualified chip capacitors fall downward along the discharge plate 5. Then workers collect the qualified chip capacitors. In this way, the qualified and unqualified chip capacitors are efficiently distinguished.

[0055] Embodiment 4: on the basis of embodiment 3, as shown in Figure 2As shown, the wiping assembly is arranged on the main support 1 and used for wiping the placement frame 71, the guide frame 72, the end face clamping frame 73 and the side edge clamping frame 75.
