Description

Technical Field

[0001] The invention belongs to the technical field of diode transportation, and in particular relates to a diode filling machine. Background Art

[0002] A diode is a basic semiconductor device with unidirectional conductivity. It is composed of two semiconductor materials. Its basic working principle is to achieve unidirectional conductivity by allowing current to flow in one direction through a PN junction while preventing it from flowing in the other direction. In power adapters, diodes are used to convert the current in the AC power supply into DC current for use in circuits or devices. In switching circuits, diodes can quickly open and close the flow of current and are used in digital circuits and switching circuits. In signal processing circuits, it can be used to shape the signal waveform and remove unnecessary parts. Diodes are an indispensable part of today's electronics industry.

[0003] Most existing circuit boards solder diodes onto printed circuits. A diode filling machine is a machine used to assist in diode installation. It can transport diodes to the installation station, but subsequent installation operations are still performed manually by bending and soldering. In addition, the positive and negative poles need to be manually identified during the diode installation process, which can easily lead to errors and reverse connection of the pins. At the same time, manual bending of the pins can easily lead to pin breakage due to improper operation. Summary of the invention

[0012] Through the above technical solution, the diode can be tested for power supply. When power is on, the extrusion conveyor belt continues to run to send out the diode. When power is off, the first pneumatic telescopic rod drives the rack to move, and the rack and the gear cooperate to drive the flip ring to rotate 180 degrees, so that the diode flips, so that the first brush contacts the second half slip ring, and the second brush contacts the first half slip ring. As the diode flips, the positive and negative poles are in the correct direction, so that current is turned on. The positive and negative poles of the diode can be detected by the rotating sleeve and the positive and negative poles of the diode are in the same direction.

[0014] Through the above technical solution, when the diode enters the rotating sleeve, the double-headed motor drives the extrusion conveyor belt to rotate, so that the pins of the diode are clamped by the elastic metal sheet. At this time, the current passes through the first brush, the second brush and the first half slip ring, the second half slip ring to perform power supply test on the diode.

[0015] Furthermore, the feeding mechanism includes a first bracket fixedly connected to the upper surface of the base plate, a pair of first fixed frames fixedly connected to the upper surface of the base plate, a hopper fixedly connected to the first bracket, a rotating roller rotatably connected in the hopper, a plurality of feeding grooves are provided on the rotating roller, a plurality of first grooves are provided on the first fixed frame, and a first motor is fixedly connected to one side of the first fixed frame.

[0017] Furthermore, a pair of rotating shafts are penetrated and rotatably connected on a pair of the first fixed frames, a disc is fixedly connected between the pair of rotating shafts, an eccentric roller is fixedly connected between the discs, the eccentric roller penetrates a rotatably connected support plate, a second groove is provided on the upper surface of the support plate, one end of the rotating shaft away from the disc is fixedly connected to a first active roller, a first active roller is provided with a first belt outside the first active roller, a first driven roller is provided inside the end of the first belt away from the first active roller, the first driven roller is fixedly connected to the rotating roller, and a button is fixedly connected to the end of the first fixed frame away from the first bracket.

[0018] Through the above technical scheme, the rotating shaft drives the disc and the first active roller to rotate respectively, the disc drives the eccentric roller to rotate, and the eccentric roller drives the support plate to rotate eccentrically. When the rotating sleeve rotates, the rubber roller on the extrusion conveyor belt releases the button to stop the first motor, thereby preventing the feeding mechanism from sending the diode into the rotating mechanism during the rotation of the rotating sleeve. The first motor will only start when the rubber roller squeezes the button.

[0019] Furthermore, the bending mechanism includes a pair of third brackets fixedly connected to the upper surface of the bottom plate, a pair of sliding rods fixedly connected between the pair of third brackets, a double-headed screw rod rotatably connected through the third brackets, a second motor fixedly connected to one side of the third bracket, an output end of the second motor is fixedly connected to the double-headed screw rod, the thread directions of the two ends of the double-headed screw rod are opposite, both ends of the double-headed screw rod are threadedly connected with a bending movable plate, a third fixed frame is fixedly connected to the bending movable plate, a second pneumatic telescopic rod is fixedly connected to the third fixed frame, an extrusion roller is fixedly and rotatably connected to the output end of the second pneumatic telescopic rod, the upper surface of the bending movable plate is arranged in a circular arc, and the bending movable plate is arranged at an incline.

[0020] Through the above technical solution, when the diode falls onto the bending movable plate, the diode will move to the bottom of the third fixed frame due to the inclined setting of the bending movable plate and the obstruction of the third fixed frame. Then the second pneumatic telescopic rod drives the extrusion roller to press down, and the extrusion roller cooperates with the bending movable plate to bend the pin and make the diode fall onto the unloading belt. If you want to change the bending width of the pin, the double-headed screw is driven to rotate by the second motor to make the bending movable plate move closer or apart along the sliding rod.

[0021] Furthermore, the unloading mechanism includes a fourth bracket fixedly connected to the upper surface of the base plate, a third motor is fixedly connected to one side of the fourth bracket, a unloading belt is rotatably connected between the fourth brackets, the third motor drives the unloading belt to rotate, and a plurality of baffles are fixedly connected to the unloading belt.

[0023] The beneficial effects of the present invention are as follows: (1) The present invention uses a feeding mechanism, and the first motor drives the rotating shaft to rotate, so that the disc and the first driven roller rotate. The disc drives the support plate to rotate through the eccentric roller, and the diodes are transported to the rotating mechanism one by one. The first driven roller drives the rotating roller to rotate, so that the diodes in the hopper can be fed one by one to the first fixed frame, avoiding interference caused by too many diodes being fed at one time, so that the diodes can be moved at intervals, thereby facilitating subsequent positive and negative pole detection and pin bending; (2) The present invention cooperates with the rotating mechanism and the flip ring. When the diode enters the rotating sleeve, the double-headed motor drives the extrusion conveyor belt to rotate, so that the pins of the diode are clamped by the elastic metal sheet. At this time, the current is tested by the cooperation between the first brush, the second brush and the first half slip ring and the second half slip ring to supply power to the diode. When power is turned on, the extrusion conveyor belt continues to run. The diode is sent out. When the power is off, the first pneumatic telescopic rod drives the rack to move. The rack and the gear cooperate to drive the flip ring to rotate 180 degrees, so that the diode flips, so that the first brush contacts the second half slip ring, and the second brush contacts the first half slip ring. As the diode flips, the positive and negative poles are in the correct direction, so that the current is turned on. The positive and negative poles of the diode can be detected by the rotating sleeve and the positive and negative poles of the diode are aligned; (3) The present invention uses a bending mechanism to drive the bending movable plate to move by the second motor, thereby changing the bending distance of the diode pin, which is convenient for adapting to different installation requirements. Then, the second pneumatic telescopic rod drives the extrusion roller to press down, cooperates with the bending movable plate, bends the pin, and pushes the diode to the unloading mechanism below. The unloading mechanism transports the bent diode to the operating station. The worker only needs to weld it without distinguishing the positive and negative poles and bending the pins.
