Description

Technical Field

[0001] This utility model relates to the field of capacitor production equipment, specifically to a rework inspection machine for capacitors. Background Technology

[0002] In existing technology, after capacitors are manufactured, in order to avoid messy stacking, each capacitor is loaded into a carrier tape, and then the surface of the carrier tape is sealed with a packaging film to prevent the capacitors from falling out. Finally, they are wound into a spool for storage. When needed, the spool is taken out and unwound. However, in actual use, it has been found that due to various reasons such as inadequate initial testing or excessive storage time, some capacitors after unwinding from the spool may have defects such as appearance flaws or electrical parameters that do not meet requirements, thus affecting their use. Therefore, it is necessary to conduct retesting. Summary of the Invention

[0003] To address the aforementioned deficiencies in existing technologies, the technical problem this invention aims to solve is how to detect the capacitance within the carrier tape in a tray. The specific technical solution is as follows: A rework inspection machine includes a frame, a worktable, a reel unwinding and retrieving mechanism, a feeding track, a capacitor moving mechanism, an appearance inspection mechanism, a disc charging device, a disc feeding and discharging mechanism, an electrical performance testing mechanism, and a loading tray winding mechanism. The worktable is mounted above the frame. The reel unwinding and retrieving mechanism is mounted on the right side above the worktable. This mechanism unwinds the carrier tape and removes the capacitors from the carrier tape, sending them to the feeding track. The feeding track is mounted on the front side above the worktable. The capacitor moving mechanism drives the capacitors in the feeding track to move from right to left. The appearance inspection mechanism is used to inspect the capacitors for appearance defects. The disc charging device is mounted on the rear side above the worktable. This device charges the capacitors. The disc feeding and discharging mechanism drives the capacitors in the feeding track into the disc charging device and drives the capacitors in the disc charging device to move out of the disc charging device and back onto the feeding track. The electrical performance testing mechanism performs CAP and LC tests on the capacitors in the feeding track. The loading tray winding mechanism is mounted on the left side above the worktable. This mechanism drives the inspected capacitors to be loaded into the carrier tape and then winds the carrier tape.

[0004] As a preferred embodiment of this utility model, the material tray unwinding and rewinding mechanism includes a carrier tape unwinding shaft, a packaging film rewinding shaft, a carrier tape limiting track, a capacitor taking component, and an active carrier tape feeding roller assembly. The carrier tape tray is installed in the carrier tape unwinding shaft, and the active carrier tape feeding roller assembly is located in front. The active carrier tape feeding roller assembly is driven by a motor to rotate the roller, thereby conveying the carrier tape forward through the carrier tape limiting track. The capacitor taking component is close to the carrier tape limiting track. The capacitor taking component uses a suction nozzle to pick up the capacitor in the carrier tape and transfer the capacitor to the feeding track. The rewinding tray is installed in the packaging film rewinding shaft, and the motor drives the packaging film rewinding shaft to rotate, so that the rewinding tray rewinds the packaging film on the surface of the carrier tape.

[0005] As a preferred embodiment of the present invention, the capacitor moving mechanism includes a left-right moving component, a front-back moving component, and a capacitor-grabbing claw. The left-right moving component drives the front-back moving component to move left and right, and the front-back moving component drives the capacitor-grabbing claw to move back and forth. The capacitor-grabbing claw is provided with multiple clamping slots for gripping capacitors.

[0006] As a preferred embodiment of this utility model, the disc feeding and discharging mechanism includes a feeding robot and a discharging robot. The feeding robot drives the capacitor in the feeding track into the disc charging device, and the discharging robot drives the charged capacitor to move out of the disc charging device and back into the feeding track.

[0007] As a preferred embodiment of the present invention, the electrical performance testing mechanism includes a first set of probes, a CAP tester, a second set of probes, and an LC tester. The first set of probes and the second set of probes are respectively used to contact the capacitor in the feed track. The first set of probes is electrically connected to the CAP tester, and the second set of probes is electrically connected to the LC tester.

[0008] As a preferred embodiment of this utility model, the appearance inspection mechanism includes a camera and a display screen. The camera takes pictures of the capacitor, and the display screen magnifies and displays the image of the defective capacitor.

[0009] Beneficial effects: The unwinding and rewinding mechanism unwinds the carrier tape and removes the capacitors from it, sending them to the feeding track. The capacitor moving mechanism drives the capacitors in the feeding track to move stepwise from right to left, so that the capacitors sequentially reach the appearance inspection mechanism, the disc feeding and unloading mechanism, the electrical performance testing mechanism, and the loading tray winding mechanism. The appearance inspection mechanism is used to check whether the capacitors have defects. The disc feeding and unloading mechanism drives the capacitors from the feeding track to the disc charging device, which charges the capacitors. The electrical performance testing mechanism performs CAP and LC tests on the capacitors in the feeding track. The loading tray winding mechanism drives the tested capacitors to be loaded into the carrier tape and then winds up the carrier tape, further avoiding defective capacitors in the carrier tape and ensuring normal production.
