Description

Technical Field

[0001] This utility model relates to the field of diode processing technology, and more specifically, to an adjustable lead-cutting device for processing light-emitting diodes. Background Technology

[0002] A diode is an electronic component with two electrodes that allows current to flow in only one direction. Many applications utilize its rectification function, while varactor diodes are used as electronically adjustable capacitors. The directional current characteristic of most diodes is commonly referred to as "rectification." The most common function of a diode is to allow current to flow in only one direction (called forward bias) and block it in the reverse direction (called reverse bias). Therefore, a diode can be thought of as an electronic check valve. Diodes have leads for easy connection to circuits. In actual production, the length of the leads usually needs to be cut off to meet the normal operating requirements of the diode.

[0003] Currently, when cutting the leads of diodes, manual cutting is usually used. This cannot guarantee the consistency of lead length, makes it inconvenient to adjust and control the cutting length, and the manual operation is time-consuming and labor-intensive, increasing the labor intensity of workers and causing great inconvenience to the lead cutting work. Therefore, this utility model proposes an adjustable lead cutting device for processing light-emitting diodes. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable cutting device for processing light-emitting diodes, which can solve the problems mentioned in the background art.

[0005] The embodiments of this utility model are implemented as follows:

[0006] An adjustable LED cutting device includes a fixed frame. A placement plate is fixedly connected to the top front of the fixed frame, and a fixed plate is fixedly connected to the top rear of the fixed frame. A drive motor is fixedly connected to the bottom center of the fixed plate. A turntable is fixedly connected to the output shaft end of the drive motor. A connecting rod is rotatably connected to the bottom edge of the turntable. Slide grooves are formed through the bottom of the left and right sides of the fixed frame. Slide rods are slidably connected inside the slide grooves. Connecting blocks are fixedly connected between opposite sides of the two slide rods. A connecting block is fixedly connected to the rear center of the connecting block. The slide bar is connected to a connecting seat. A fixing rod is fixedly connected to the top of the slide bar. A mounting bracket is fixedly connected to the top of the fixing rod. A pointer is fixedly connected to the middle of the bottom left and right sides of the mounting bracket. A scale is fixedly connected to the top left and right sides of the fixing bracket. Placement slots are formed on the top of the placement plate and the bottom inner side of the mounting bracket. A knife slot is formed through the middle of the bottom inner side of the mounting bracket. An electric telescopic rod is fixedly connected to the middle top of the mounting bracket. A connecting plate is fixedly connected to the end of the output shaft of the electric telescopic rod. A cutter is fixedly connected to the middle bottom of the connecting plate.

[0007] As a further preferred embodiment of this technical solution, the input ends of the drive motor and the electric telescopic rod are electrically connected to the output end of an external power supply, and the output shaft end of the electric telescopic rod passes through the inner top of the mounting frame.

[0008] As a further preferred embodiment of this technical solution, the end of the connecting rod is rotatably connected to the interior of the connecting seat, and the two sliding rods are fixedly connected to baffles at their far ends.

[0009] As a further preferred embodiment of this technical solution, the pointer and the cutter are located on the same plane.

[0010] As a further preferred embodiment of this technical solution, the connecting plate is characterized in that a limiting rod is slidably connected through the bottom four corners of the connecting plate, a U-shaped frame is fixedly connected to the bottom end of the limiting rod, and a first fixing seat is symmetrically fixedly connected to the front and rear parts of the top of the U-shaped frame. A sleeve is rotatably connected inside the first fixing seat, and a spring is fixedly connected to the bottom inner side of the sleeve. A second fixing seat is fixedly connected to the bottom four corners of the connecting plate, and a connecting rod is rotatably connected inside the second fixing seat.

[0011] As a further preferred embodiment of this technical solution, the top of the limiting rod is fixedly connected to a circular plate, and the top end of the spring is fixedly connected to the bottom end of the connecting rod.

[0012] As a further preferred embodiment of this technical solution, the connecting rod is slidably connected to the inside of the sleeve, and the outer side wall of the connecting rod is in contact with the inner side wall of the sleeve.

[0013] The beneficial effects of this utility model are:

[0014] By configuring the drive motor, turntable, connecting rod, and connecting block, starting the drive motor drives the turntable to rotate. The rotation of the turntable causes the connecting rod to deflect, which in turn moves the connecting seat, which in turn moves the connecting block, causing the slide rod to move, which in turn moves the fixed rod, which in turn moves the mounting bracket, which in turn moves the cutter. By using the pointer and scale, the cutting length can be easily adjusted and controlled, avoiding manual cutting, saving time and effort, reducing the labor intensity of workers, and bringing great convenience to the cutting work.

[0015] By configuring the connecting rod, sleeve, spring, and U-shaped frame, when the electric telescopic rod drives the connecting plate to descend, the U-shaped frame first contacts the pin, and then the connecting plate continues to drive the cutter to descend, causing the connecting plate to slide outside the limit rod. This allows the connecting rod to rotate around the second fixed seat, and then slide inside the sleeve, compressing the spring. The spring's reaction force presses the pin of the LED firmly, thus preventing the pin from lifting up at the cut during cutting and preventing any impact on the cutting quality.

The top of the fixing rod 11 is fixedly connected to a mounting bracket 12. The middle of the bottom left and right sides of the mounting bracket 12 is fixedly connected to a pointer 13. The top left and right sides of the fixing bracket 1 are fixedly connected to a scale 14. The top of the placement plate 2 and the bottom inner side of the mounting bracket 12 are provided with a placement groove 15. The middle of the bottom inner side of the mounting bracket 12 is provided with a through-cutting groove 16. The middle of the top of the mounting bracket 12 is fixedly connected to an electric telescopic rod 17. The end of the output shaft of the electric telescopic rod 17 is fixedly connected to a connecting plate 18. The middle of the bottom of the connecting plate 18 is fixedly connected to a cutter 19.

[0029] like Figure 2 As shown, the input ends of the drive motor 4 and the electric telescopic rod 17 are electrically connected to the output end of the external power supply, and the output shaft end of the electric telescopic rod 17 passes through the top inner side of the mounting bracket 12.

[0030] like Figure 2 As shown, the end of the connecting rod 6 is rotatably connected to the interior of the connecting seat 10, and the two sliding rods 8 are fixedly connected to baffles at their far ends.

[0035] This utility model provides an adjustable cutting device for processing light-emitting diodes. The specific working principle is as follows: During normal use, the leads of the light-emitting diode are placed in the placement slot 15. The drive motor 4 is started, which drives the turntable 5 to rotate. The rotation of the turntable 5 causes the connecting rod 6 to deflect, which drives the connecting seat 10 to move, which in turn drives the connecting block 9 to move, which causes the sliding rod 8 to move, which drives the fixing rod 11 to move, which causes the mounting bracket 12 to move, which in turn drives the cutting blade 19 to move. The cutting length is controlled by the cooperation of the pointer 13 and the scale 14.

[0036] Then, the electric telescopic rod 17 is activated, causing the connecting plate 18 to descend. This causes the U-shaped frame 21 to first contact the pin. Then, the connecting plate 18 continues to drive the cutter 19 to descend, causing the connecting plate 18 to slide outside the limit rod 20. This causes the connecting rod 26 to rotate around the second fixed seat 25, and then slide inside the sleeve 23, compressing the spring 24. Through the reaction force of the spring 24, the pin of the light-emitting diode is pressed. When the cutter 19 contacts the pin, it cuts the pin.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
