[0002] Capacitors are commonly used electronic components in circuits and are widely used in circuits. Before capacitors are applied to circuits, they need to go through processes such as cutting, folding, aging and testing.

The first bending mechanism, the second bending mechanism and the third bending mechanism are used to bend the soldering of the electronic components to the two outer sides in turn, that is, one solder foot is bent to the left and the other solder foot is bent to the right; bend backward, and then bend the free end of the soldering in the opposite direction to form a U shape, and then collect the capacitor into the collection device through the transfer manipulator; and the collected capacitor will be directly applied to the circuit.

[0003] During the continuous clamping process, the capacitor will be deformed due to the clamping force; and the capacitor will also be deformed during the aging process; this will lead to defective capacitors, so it is necessary to check whether the capacitor's shape is deformed before collection.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0030] In one embodiment of the capacitor bulge detection and sorting device of the present invention, please refer to Figures 1 to 4 ; The capacitor bulge detection and sorting device is arranged between the capacitor folding leg forming machine 1 and the capacitor collecting device 2, and is used to detect and sort the bulged capacitor.

[0031] The capacitor bulge detection and sorting device includes a clamping mechanism 100, a machine base 200, a turntable 300, a detection mold 400, a detection probe 500 and a material picking robot 600.

[0032] The turntable 300 is rotatably arranged on the base 300. Specifically, the turntable 300 is arranged on the rotating disk of the divider, and the divider is arranged on the base 300. The divider can be driven by a separate motor, or can be driven by the driving motor of the capacitor folding device to realize linkage with the capacitor folding device. The detection mold 400 is arranged on the turntable 300, and the detection mold 400 is provided with a positioning hole 401. The positioning hole 401 can locate and detect whether there is a bulge in the shape of the capacitor. If there is a bulge in the capacitor, the capacitor cannot be completely dropped into the positioning hole 401, and then the detection probe 500 is used to detect the capacitor position in the positioning hole 401. The material picking manipulator 600 is arranged on the base 200, and is used to clamp the capacitor in the positioning hole 401. The clamping mechanism 100 is arranged on one side of the turntable 300, and is used to clamp the capacitor and place it in the positioning hole 401. The clamping mechanism 100 may be a transfer clamping mechanism of the capacitor leg folding and forming machine, or may be a flip clamping mechanism disposed between the capacitor leg folding and forming machine and the turntable 300 .

[0033] In the present embodiment, the clamping mechanism 100 can clamp the capacitor that has completed the folding and aging process and place it in the positioning hole 401 of the detection mold 400, and detect the height position of the capacitor by the detection probe 500, so as to determine whether the appearance of the capacitor is deformed. If the capacitor is not deformed, when the capacitor is placed in the positioning hole 401, the capacitor can fall to the fixed position of the positioning hole 401. If the appearance of the capacitor is deformed, the capacitor will be stuck in the positioning hole 401 and cannot reach the fixed position, and the height position of the capacitor can be detected by the detection probe 500, so that it can be determined that the capacitor is deformed. When the capacitor is rotated to the specified position by the rotating disk 300, it can be sorted out and placed in the specified position by the material taking manipulator 600, so that the capacitor with bulging deformation is sorted out, avoiding the capacitor with deformed appearance to be collected and applied to the circuit.

[0034] Further, refer to Figures 1 to 4 The capacitor bulging detection and sorting device also includes a sorting robot 700 for removing capacitors with bad positioning holes. In this embodiment, the deformed bulging capacitors can be removed by the sorting robot 700, and the material removal robot 600 can remove qualified capacitors and place them in the collection device.

[0035] Further, an embodiment of the detection probe 500 is specifically described in Figure 3 and Figure 4, the detection probe 500 is located at the bottom side of the turntable 300 and is fixedly connected to the base 200. The positioning hole 401 is a through hole, and the turntable 300 drives the positioning hole 401 to pass through the top side of the detection probe 500. Thus, the height position of the bottom of the capacitor can be detected by the detection probe 500. Specifically, the detection probe 500 can be located on one side of the clamping mechanism 100, so when the clamping mechanism 100 clamps the capacitor to the positioning hole 401, the position of the capacitor can be detected.

[0036] Further, please refer to Figure 3 and Figure 4 , the bottom side of the rotating disk 300 is also provided with a fixed disk 800, and the fixed disk 800 can be fixedly mounted on the fixed seat of the divider. The detection probe 500 can be arranged on the fixed disk 800, and the top of the detection probe 500 is not higher than the top of the fixed disk 300. Therefore, when the capacitor is placed in the positioning hole 401, the qualified capacitor will fall, and the bottom of the capacitor will be supported on the fixed disk 800, so the bottom of the capacitor can be detected by the detection probe 500, so as to judge that there is no problem of bulging deformation in the appearance of the capacitor. If the bottom of the capacitor cannot fall to the top of the fixed disk 800, the detection probe 500 cannot detect the bottom of the capacitor, so that it can be judged that the capacitor is stuck in the positioning hole 401 due to bulging deformation, so that the detected signal can be fed back to the control system, and the control system controls the sorting robot 700 to take out the capacitor. Term, the detection probe 500 can be a photoelectric switch or a distance sensor.

[0037] Furthermore, a protrusion 801 is further provided on the fixed disk 800, and the protrusion 801 is located on the motion track of the detection mold 400, and a guide 802 is provided between the end of the protrusion 801 and the upper surface of the fixed disk 800. In this embodiment, when the capacitor rotates with the turntable 300, the bottom of the capacitor will gradually contact the guide 802, thereby lifting the capacitor upward, making it easier for the material picking robot 600 to pick up the capacitor.

[0038] Another embodiment of the fixed plate 800 is provided with a lifting member; specifically, please refer to Figure 8 A cylinder 803 is provided on the fixed plate 800. One group of cylinders of the two cylinders 803 is used to push out defective products, and the other group of cylinders is used to push qualified products to the side.

[0039] Further, another embodiment of the detection probe 500 is specifically described in Figure 7 The lower end of the detection mold 400 is provided with a mounting hole 402, the mounting hole 402 is vertically arranged with the positioning hole 401 and passes through the positioning hole 402, and the detection probe 500 is arranged in the mounting hole 402.

[0040] Further, another embodiment of the detection probe 500 is specifically described in Figure 6The detection probe 500 can be arranged at the center of the top side of the turntable 300 or on the base 200, and the detection probe 500 faces the detection mold 400. When the detection probe 500 is arranged at the center of the turntable 300, a clearance hole is arranged on the turntable 300, and the fixed part of the divider can extend from the clearance hole, so the detection probe 500 can be arranged at the fixed part of the divider.

[0041] Furthermore, the detection mold 400 is detachably connected to the rotating disk 300; the rotating disk 300 is provided with a through hole, and the detection mold 400 is arranged in the through hole. In this embodiment, different detection molds 400 can be replaced to realize detection and sorting of different capacitances.

[0042] For further information, please refer to Figure 3 , Figure 4 and Figure 6 The upper surface of the detection mold 400 is also provided with a limiting protrusion 403, which is used to limit the two pins of the capacitor. In this embodiment, the pins of the capacitor that are bent and formed can be distributed on both sides of the limiting protrusion 403, so as to avoid the problem of the capacitor rotating.

[0043] Further, refer to Figure 5 A blowing nozzle 900 is also provided above the detection mold 400 for blowing air toward the top side of the capacitor. The blowing nozzle 900 is located on one side of the clamping mechanism 100. When the clamping mechanism 100 places the capacitor in the positioning hole 401, the blowing nozzle 900 can be used to blow air toward the top side of the capacitor, so that the capacitor falls into the positioning hole 401, thereby avoiding the problem of misjudgment of the capacitor due to tilt.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
