Description

Technical Field

[0001] The invention relates to the technical field of diode sorting, and in particular to a diode welding sorting device. Background Art

[0002] Diode, a device with two electrodes in electronic components, only allows current to flow in one direction, and many uses are for its rectifying function. Varicap diodes are used as electronic adjustable capacitors. The current directionality of most diodes is usually called the "rectifying" function. The most common function of a diode is to allow current to flow in one direction only (called forward bias) and block it in the reverse direction (called reverse bias). Therefore, a diode can be thought of as an electronic version of a current check valve. In the automated production process, especially when welding diodes to circuit boards, automatic feeding of diodes is required, so the diodes need to be placed in the same direction for feeding. The shape of the diodes is irregular, and the existing design requires a complex structure to implement this technology, and the effect is not ideal. Summary of the invention

[0004] The technical solution of the present invention is:

[0007] Furthermore, the pulling device includes a motor, a winding wheel is installed on the output shaft of the motor, a pulling wire is wound around the winding wheel, the pulling wire passes through the side wall of the vertical pipe and is fixedly connected to the inner wall of the corresponding arc-shaped elastic sheet, and the motor is connected to the controller.

[0008] Furthermore, the upper end of the arc-shaped elastic sheet is connected to the inner wall of the vertical tube via a hinge seat, and the inner side of the arc-shaped elastic sheet is connected to the inner wall of the vertical tube via a spring.

[0009] Furthermore, a plurality of evenly distributed air outlets are formed in a ring shape on the upper conical tube, and an electronic valve is installed at the air outlet.

[0014] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] like Figures 1 to 3As shown, the present invention provides a diode welding sorting device, including a vibration plate 2, a plurality of sorting devices are connected in series at the lower side of the vibration plate, the sorting device includes a vertical tube 1, a first guide tube 3 and a second guide tube 4 are fixedly installed inside the upper end and the lower end of the vertical tube, respectively, a flared conical tube 5 is fixedly installed at the lower end of the first guide tube and the upper end of the second guide tube, the large diameter end of the conical tube is fixedly connected to the inner wall of the vertical tube, a plurality of arc-shaped elastic sheets 6 are annularly arranged between the two conical tubes in the vertical tube, and the upper end of the arc-shaped elastic sheet 6 is connected to the inner wall of the vertical tube. Connected by a hinge seat, the lower ends of several arc-shaped elastic sheets are close to each other, and several evenly distributed grooves 7 are opened on the inner side of the arc-shaped elastic sheet. The opening of the groove 7 is inclined upward and the bottom surface is perpendicular to the inner side of the arc-shaped sheet. The inner side of the arc-shaped elastic sheet is connected to the sensor, and the inner side of the arc-shaped elastic sheet is connected to the inner wall of the vertical tube through a spring 8. A pulling device is arranged on the side of the vertical tube corresponding to the position of the arc-shaped elastic sheet, and the moving end of the pulling device is connected to the inner side of the arc-shaped elastic sheet. The arc-shaped elastic sheet can be pulled to rotate around the hinge seat and move toward the inner wall of the vertical tube through the pulling device.

[0017] The sensor is a pressure sensor. A through hole is provided on the side wall of the vertical tube corresponding to the position of the pressure sensor. A push rod 9 is arranged in the through hole. The outer end of the push rod is connected to the pressure sensor. The inner end of the push rod is hingedly connected to the inner side of the arc-shaped elastic sheet through an inclined rod. When the diode touches the arc-shaped sheet, the force is transmitted to the pressure sensor through the inclined rod and the push rod, and the pressure sensor transmits the signal to the controller. The controller controls the pulling device on the opposite side of the pressure sensor to pull the corresponding arc-shaped elastic sheet.

[0018] The pulling device includes a motor 10, a winding wheel 11 is installed on the output shaft of the motor, a pull wire 12 is wound around the winding wheel, and the pull wire 12 passes through the side wall of the vertical pipe and is fixedly connected to the inner wall of the corresponding arc-shaped elastic sheet. The motor is connected to the controller. When the controller controls the motor to work, the winding wheel rotates, and the corresponding arc-shaped elastic sheet can be pulled to rotate through the pull wire.

[0019] The conical tube 5 located on the upper side is provided with several evenly distributed air outlets in a ring shape, and the air outlets are provided with electronic valves 13, which are connected to the controller. One side of the upper part of the vertical tube is connected to the air inlet pipe 14, and the other end of the air inlet pipe is connected to a constant pressure pump. The controller controls several electronic valves to open and close in sequence, and only one electronic valve is in the open state at a time. When the pin of the diode falls downward, the air blown through the electronic valve can tilt the diode, ensuring that the end of the pin has a higher probability of being stuck in one of the card slots.

[0020] Working principle: When in use, first place the diode 15 into the vibration plate. As the vibration plate vibrates, the diodes fall into the first guide tube in sequence. When the diode falls to the upper side of the arc-shaped elastic sheet, the air blown by the electronic valve can tilt the diode to ensure that the end of the pin can be stuck in one of the slots. At this time, the diode touches the sensor, and the controller controls the pressure sensor and the pulling device on the opposite side to pull the corresponding arc-shaped elastic sheet (such as Figure 3 As shown in the figure), due to the effect of the card slot, the diode will flip over and continue to fall, so that the diode pins face upward and continue to fall downward. After passing through several sorting devices, most of the diodes can be distributed with their pins facing upward, and then continue to move to the next automated welding process to sort them for welding work and adjust the diodes with the wrong direction. The above-described embodiments of the present invention do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the claims of the present invention.
