[0002] Packaging is the process of assembling an integrated circuit into a final chip product. Simply put, it is to place the bare integrated circuit chip on a substrate that serves as a carrier, lead out the pins, and then fix and package them into a whole. As a device for signal emission and reception, the infrared pair of tubes is applied in many fields. The infrared pair of tubes is installed on a circuit board. The first method is to use a traditional surface-mounted infrared emitting tube, which is soldered flat on the circuit board. The other method is to directly install the two legs of the infrared emitting tube standard part in the circuit board to complete the assembly of the light curtain bar. However, both of the above installation methods have certain limitations. Moreover, for assembly, the emitting tube and the receiving tube are often installed independently by hand in the device, that is, after installing the emitting tube, the receiving tube is installed, which is time-consuming and laborious.

[0025] Refer to Figures 1-6As shown in the figure, a packaging structure of an infrared pair tube with integrated frame bending includes a connecting rod 1. On one side of the connecting rod 1, there is a transmitting end support frame 2, and on the other side of the connecting rod 1, there is a receiving end support frame 3. At the end of the transmitting end support frame 2, there is a transmitting cross bar 4, and on the transmitting cross bar 4, there is a transmitting lead frame 5. At the end of the receiving end support frame 3, there is a receiving cross bar 6, and on the receiving cross bar 6, there is a receiving lead frame 7. On the transmitting lead frame 5, there is an infrared transmitting component 8, and on the receiving lead frame 7, there is an infrared receiving component 9. A part of the transmitting end support frame 2 and the receiving end support frame 3 are both bent at 90 degrees with the connecting rod. The infrared transmitting component 8 and the infrared receiving component 9 are distributed opposite to each other, and the signal emitted by the infrared transmitting component can be received by the infrared receiving component.

[0026] The transmitting end support frame 2, the receiving end support frame 3 and the connecting rod 1 are of an integrally formed structure.

[0027] The infrared receiving component 8 includes an infrared transmitting tube 81 and a transmitting PIN foot 82. The transmitting PIN foot 82 is connected to the transmitting cross bar 4, and the infrared transmitting tube 81 is connected to the transmitting PIN foot 82 through a wire. The infrared receiving component 9 includes an infrared receiving tube 91 and a receiving PIN foot 92. The receiving PIN foot 92 is connected to the receiving cross bar 6, and the infrared receiving tube 91 is connected to the receiving PIN foot 92 through a wire. A lens 10 is sleeved on both the infrared transmitting tube 81 and the infrared receiving tube 91. The lens 10 is arranged to be connected to a colloid seat 11. The signal emitted by the infrared transmitting tube can pass through the lens and then be received by the infrared receiving tube. Colloid seats are respectively installed on the transmitting PIN foot and the receiving PIN foot to ensure the stable assembly of the infrared transmitting tube and the infrared receiving tube.

[0028] A plastic shell 12 in a concave shape is injection-molded between the transmitting end support frame 2 and the receiving end support frame 3. A concave groove 13 is formed in the middle of the plastic shell 12. One side of the plastic shell 12 integrally wraps the infrared transmitting component 8, and the other side of the colloid seat 12 integrally wraps the infrared receiving component 9. The transmitting PIN foot 82 and the receiving PIN foot 92 both extend to the outside of the plastic shell 12. A wire slot opening 14 is provided on the plastic shell 12 corresponding to the position of the lens. The plastic shell can be set to black and is an opaque structure. Using the wire slot opening will not hinder the transmission and reception of signals.

[0031] Reference Figure 6As shown, by supplying power to the infrared emitting tube and the infrared receiving tube, the infrared emitting tube emits a signal. When there is no object blocking between the infrared emitting tube and the infrared receiving tube, the optical signal emitted by the infrared emitting tube is received by the infrared receiving tube and converted into an electrical signal, which is sent to the processing chip A for corresponding processing.

[0032] In the present utility model, as Figures 1-5 , when assembling the infrared emitting component and the infrared receiving component, the emitting support frame and the receiving support frame are not bent first. At this time, the infrared emitting component and the infrared receiving component can be encapsulated simultaneously on the assembling device, and then the emitting support frame and the receiving support frame are bent. At this time, a facing space is formed between the infrared emitting component and the infrared receiving component, and then the plastic outer shell is injection molded. The automatic machine cuts off the corresponding emitting cross bar and receiving cross bar to obtain a single accessory that integrates the infrared emitting tube and the infrared receiving tube at the same time, which can be directly assembled into the product device as a whole without separately installing the infrared emitting tube and the infrared receiving tube in the product device.
