[0002] A duplexer is an electronic component or assembly used in communication systems. Its main function is to allow signals in both directions to use the same frequency band simultaneously without interfering with each other. Duplexers are usually used in full-duplex communication systems so that the transmitter and receiver can share a common antenna or transmission path.

[0003] The core component of the duplexer is the internal circuit board. Figure 5 As shown, the existing duplexer circuit board panel 1 is composed of a plurality of circuit board units 1-1, and a connecting portion 1-2 is provided between adjacent circuit board units 1-1, and the plurality of circuit board units are connected as a whole through the connecting portion 1-2. During assembly, the duplexer circuit board panel 1 needs to be punched by a punching device, and the connecting portion between two adjacent circuit board units 1-1 needs to be punched off, so that the duplexer circuit board panel 1 is decomposed into a plurality of independent circuit board units 1-1, and then the circuit board units are debugged and assembled to obtain a duplexer.

[0004] When a traditional stamping device is punching a duplexer circuit board panel, the operator first places the duplexer circuit board panel 1 on the lower die on the stamping device, and punches the connecting part on the duplexer circuit board panel 1 to break it by moving the upper die downward. After the stamping is completed, the upper die moves upward to reset, and then the operator needs to remove the multiple disassembled circuit board units from the lower die, and then punch the next duplexer circuit board panel in the same way.

[0005] In the existing punching method, after the punching is completed, the operator needs to manually remove the multiple circuit board units from the lower die, which takes a certain amount of time, resulting in a long unloading time and affecting the processing efficiency.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0023] like Figures 1 to 5 As shown, a duplexer panel splitting punching device includes a bracket 2, a lower punching die 3, and an upper punching die 4. The lower punching die 3 is provided with rotating shafts 3-4 at both ends. The rotating shafts 3-4 at both ends of the lower punching die 3 are rotatably connected to the bracket 2. The rotating shaft 3-4 at one end of the lower punching die 3 is connected to the motor 5. The upper punching die 4 is located directly above the lower punching die 3. The bracket 2 is provided with a lifting mechanism for driving the upper punching die to move up and down. A material frame 9 is provided below the lower punching die 3.

[0024] When punching the duplexer circuit board panel 1, the utility model first places the duplexer circuit board panel 1 on the lower punching die, and the lower punching die 3 is in a horizontal state at this time. Then the lifting mechanism drives the upper punching die to descend and punch the duplexer circuit board panel 1. After the punching is completed, the upper punching die moves upward and resets. Then the motor 5 first drives the lower punching die to rotate 180 degrees, so that the circuit board unit 1-1 placed on the lower punching die falls into the material frame 9 below, thereby completing the unloading of the circuit board unit 1-1. Then the motor 5 continues to drive the lower punching die to flip 180 degrees to restore the lower punching die to its initial state; punch the next duplexer circuit board panel 1 in the same way. The utility model realizes the rapid unloading of the circuit board unit 1-1 by flipping the lower punching die, shortens the unloading time, and improves the processing efficiency.

[0025] The lifting mechanism includes a lifting drive device 6 arranged on the bracket 2, the lifting drive device 6 is connected to the upper punching die, the upper punching die is provided with a guide column 7, the bracket 2 is provided with a guide hole corresponding to the guide column 7, and the guide column 7 passes through the guide hole.

[0026] In this embodiment, the lifting drive device 6 is a hydraulic cylinder, wherein the cylinder body of the hydraulic cylinder is fixedly arranged on the bracket 2, and the piston rod of the hydraulic cylinder is connected to the upper punching die.

[0027] The lower punching die 3 is provided with a lower punching portion 3-2, and the upper punching die 4 is provided with an upper punching portion 4-2 corresponding to the lower punching portion 3-2. A cutting edge is provided at the lower end of the upper punching portion 4-2, and the connecting portion 1-2 on the duplexer circuit board panel 1 is cut off by the cutting edge, thereby realizing the separation between the circuit board units 1-1.

[0028] The lower punching die 3 is provided with a plurality of first avoidance grooves 3-1 corresponding to the circuit board units 1-1 on the duplexer circuit board panel 1, and the upper punching die 4 is provided with a plurality of second avoidance grooves 4-1 corresponding to the circuit board units 1-1 on the duplexer circuit board panel 1.

[0029] Since there are some electronic components on the circuit board, these electronic components protrude a certain height from the surface of the circuit board; by arranging the first avoidance groove 3-1 and the second avoidance groove on the upper punching die and the lower punching die, the protruding electronic components on the circuit board can be avoided to prevent the electronic components from being crushed.

[0030] The lower punching die is provided with a positioning boss 3-3, and the upper punching die is provided with a positioning boss 3-3 avoidance groove corresponding to the positioning boss 3-3. When the duplexer circuit board panel 1 is placed on the lower punching die, the duplexer circuit board panel 1 abuts against the positioning boss 3-3, thereby realizing the positioning of the duplexer circuit board panel 1.

[0031] Furthermore, positioning holes 3-5 are provided at both ends of the lower punching die, and a tightening oil cylinder 8 corresponding to the positioning holes 3-5 is provided on the bracket 2; when the lower punching die is in a punching state, the piston rod on the tightening oil cylinder 8 extends into the positioning hole 3-5 on the lower punching die; the angle state of the lower punching die is locked by the tightening oil cylinder 8, thereby improving the stability of the lower punching die during punching. When the lower punching die needs to be rotated and the circuit board unit 1-1 is unloaded, the piston rod on the tightening oil cylinder 8 withdraws from the positioning hole 3-5, so that the lower punching die can be flipped under the drive of the motor 5.

[0032] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
