A cutting device for high-power diode chips

Abstract

This utility model discloses a cutting device for high-power diode chips, relating to the field of cutting devices. It includes a guide cylinder, with a pair of limiting plates fixedly connected to its surface. A pair of connecting plates are slidably connected to the upper surface of the guide cylinder, and a common driving plate is fixedly connected to the surfaces of the connecting plates. The connecting plates drive a feeding cylinder, pushing the diode substrate inside the feeding cylinder to be cut by a rotating cutting disc. When the feeding cylinder continues to move and comes into contact with the surface of the inclined plate, it rotates at an angle on the surface of the connecting shaft. Through the connection of the positioning plate, a torsion spring is tensioned, and the feeding cylinder tilts to discharge the cut diode substrate. When the output end of the multi-stage electric telescopic rod extends, the tension of the torsion spring is released, causing the feeding cylinder to return to a horizontal position. Multiple stacked diode substrates fall back into the feeding cylinder. The advantage of this design is that the cutting operation can be repeated, achieving an automatic material discharge effect.

Description

Technical Field

[0001] This utility model relates to the field of cutting devices, and in particular to a cutting device for high-power diode chips. Background Technology

[0002] A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). A diode has two electrodes: a positive terminal, also called the anode, and a negative terminal, also called the cathode. When a forward voltage is applied between the two terminals, the diode conducts; when a reverse voltage is applied, the diode is cut off. The conduction and cutoff of a diode are equivalent to the on and off states of a switch. A diode chip is an electronic component that integrates multiple diodes onto a single semiconductor chip, primarily used for functions such as rectification, voltage regulation, switching, and amplification.

[0003] In diode chip processing, a cutting device is required. Traditional cutting equipment cannot achieve automatic unloading after cutting, and cannot automatically discharge the cut material, thus affecting the cutting efficiency. To address the above problems, a high-power diode chip cutting device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a cutting device for high-power diode chips to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for high-power diode chips, comprising a guide cylinder, a pair of limiting plates fixedly connected to the surface of the guide cylinder, a pair of connecting plates slidably connected to the upper surface of the guide cylinder, a common driving plate fixedly connected to the surface of the pair of connecting plates, a pair of lifting plates fixedly connected to the upper surface of the guide cylinder, a common cross plate fixedly connected to the opposite surfaces of the pair of lifting plates, a plurality of diode plates placed between the pair of limiting plates and the cross plate, and a cutting and feeding mechanism provided on one side of the connecting plate.

[0006] Preferably, the cutting and feeding mechanism includes a connecting shaft fixedly connected to the surface of the connecting plate, a feeding cylinder rotatably connected to the surface of the connecting shaft, a positioning plate fixedly connected to the surface of the feeding cylinder, and one end of the connecting shaft rotatably connected to the surface of the positioning plate.

[0007] Preferably, an annular block is fixedly connected to the surface of the connecting shaft, and a torsion spring is sleeved on the surface of the connecting shaft. One end of the torsion spring is fixedly connected to the surface of the annular block, and the other end of the torsion spring is fixedly connected to the surface of the positioning plate.

[0008] Preferably, the surface of the feeding cylinder is provided with clearance holes, and the distance between the lower surface of the cross plate and the upper surface of the connecting plate is equal to the thickness of the diode plate.

[0009] Preferably, a motor is fixedly connected to the surface of the guide cylinder, and a cutting disc is fixedly connected to the output end of the motor, with the cutting disc corresponding to the position of the clearance hole.

[0010] Preferably, a fixing plate is fixedly connected to the surface of the guide cylinder, an inclined plate is fixedly connected to the surface of the fixing plate, a controller is fixedly installed on the surface of the guide cylinder, a multi-stage electric telescopic rod is fixedly connected to the surface of the guide cylinder, the output end of the multi-stage electric telescopic rod is fixedly connected to the surface of the driving plate, and a stabilizing plate is fixedly connected to the upper surface of the guide cylinder.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] In this invention, the connecting plate drives the feeding cylinder to push the diode material inside the feeding cylinder to be cut by the rotating cutting disc. When the feeding cylinder continues to move and comes into contact with the surface of the inclined plate, it causes the feeding cylinder to rotate at an angle on the surface of the connecting shaft. Through the connection of the positioning plate, the torsion spring is tensioned, and the feeding cylinder tilts to discharge the cut diode material. When the output end of the multi-stage electric telescopic rod extends, the tension of the torsion spring is released, causing the feeding cylinder to reset and remain horizontal. Multiple stacked diode materials fall back into the feeding cylinder. The advantage of this is that the cutting operation can be repeated to achieve an automatic material discharge effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Reference Figures 1-4 The high-power diode chip cutting device shown includes a guide cylinder 1, a pair of limiting plates 2 fixedly connected to the surface of the guide cylinder 1, a pair of connecting plates 5 slidably connected to the upper surface of the guide cylinder 1, a common driving plate 11 fixedly connected to the surface of the pair of connecting plates 5, a pair of lifting plates 10 fixedly connected to the upper surface of the guide cylinder 1, a common cross plate 9 fixedly connected to the opposite surface of the pair of lifting plates 10, a plurality of diode plates 6 placed between the pair of limiting plates 2 and the cross plate 9, and a cutting and feeding mechanism provided on one side of the connecting plate 5.

[0021] With the above structure, by setting a pair of limiting plates 2 and cross plates 9 to cooperate, the multiple diode plates 6 are stacked stably. By setting a pair of lifting plates 10 to fix the cross plates 9, and by setting a cutting and discharging mechanism, a fast cutting and discharging operation is achieved.

[0022] Preferably, the cutting and feeding mechanism includes a connecting shaft 16 fixedly connected to the surface of the connecting plate 5, a feeding cylinder 15 rotatably connected to the surface of the connecting shaft 16, a positioning plate 19 fixedly connected to the surface of the feeding cylinder 15, and one end of the connecting shaft 16 rotatably connected to the surface of the positioning plate 19.

[0023] By setting up a feeding cylinder 15, a diode plate 6 is placed inside, and by setting up a positioning plate 19, the support of the connecting shaft 16 is kept stable.

[0024] Preferably, an annular block 17 is fixedly connected to the surface of the connecting shaft 16, and a torsion spring 18 is sleeved on the surface of the connecting shaft 16. One end of the torsion spring 18 is fixedly connected to the surface of the annular block 17, and the other end of the torsion spring 18 is fixedly connected to the surface of the positioning plate 19.

[0025] By setting the annular block 17, support is maintained on one end of the torsion spring 18. By setting the torsion spring 18, it is convenient to drive the feeding cylinder 15 to rotate and reset.

[0026] Preferably, the surface of the feeding cylinder 15 is provided with a clearance hole 20, and the distance between the lower surface of the cross plate 9 and the upper surface of the connecting plate 5 is equal to the thickness of the diode plate 6.

[0027] By setting the clearance hole 20, the cutting operation of the cutting disc 8 is spatially cleared. By setting the distance between the lower surface of the cross plate 9 and the upper surface of the connecting plate 5 to be equal to the thickness of the diode plate 6, it is ensured that multiple stacked diode plates 6 fall into the feeding cylinder 15 in sequence.

[0028] Preferably, a motor 3 is fixedly connected to the surface of the guide cylinder 1, and a cutting disc 8 is fixedly connected to the output end of the motor 3. The cutting disc 8 corresponds to the position of the clearance hole 20.

[0029] By setting motor 3, the cutting disc 8 is driven to rotate.

[0030] Preferably, a fixing plate 13 is fixedly connected to the surface of the guide cylinder 1, an inclined plate 14 is fixedly connected to the surface of the fixing plate 13, a controller 4 is fixedly installed on the surface of the guide cylinder 1, a multi-stage electric telescopic rod 12 is fixedly connected to the surface of the guide cylinder 1, the output end of the multi-stage electric telescopic rod 12 is fixedly connected to the surface of the drive plate 11, and a stabilizing plate 7 is fixedly connected to the upper surface of the guide cylinder 1.

[0031] By setting a fixed plate 13, a fixed support inclined plate 14 is provided. When the surface of the inclined plate 14 contacts the surface of the feeding cylinder 15, the feeding cylinder 15 is driven to rotate under force. At this time, the cut diode board 6 is discharged from the feeding cylinder 15. By setting a multi-stage electric telescopic rod 12, the plate 11 and the connecting plate 5 are driven to move.

[0032] The working principle of this utility model is as follows: A high-power diode chip cutting device sends an electrical signal through a controller 4 to control the output end of a multi-stage electric telescopic rod 12 to move, driving the moving plate 11 and connecting plate 5 to move. The controller 4 also sends an electrical signal to control the output end of a motor 3 to rotate. The motor 3 drives the cutting disc 8 to rotate, and the connecting plate 5 drives the feeding cylinder 15 to push the diode plate 6 inside the feeding cylinder 15 to be cut by the rotating cutting disc 8. The stabilizing plate 7 keeps the diode plate 6 stable during cutting, and the clearance hole 20 provides space clearance for the rotating cutting disc 8. When the feeding cylinder 15 continues to move and comes into contact with the surface of the inclined plate 14, it causes the feeding cylinder 15 to rotate at an angle on the surface of the connecting shaft 16. At this time, the torsion spring 18 is tensioned through the connection of the positioning plate 19, and the feeding cylinder 15 tilts to discharge the cut diode plate 6. When the output end of the multi-stage electric telescopic rod 12 extends, the tension of the torsion spring 18 is released at the same time, causing the feeding cylinder 15 to return to a horizontal position. Multiple stacked diode plates 6 fall back into the feeding cylinder 15 for repeated cutting operations.
