[0002] Wavelength division multiplexers are used to combine optical signals of different wavelengths into one beam and transmit it along a single optical fiber, and then separate the optical signals of different wavelengths at the receiving end. This technology is called wavelength division multiplexing. It makes full use of the low-loss band of optical fiber and can simultaneously transmit multiple optical signals of different wavelengths in the same optical fiber, thereby greatly increasing the transmission capacity of the optical fiber. The wavelength division multiplexer combines optical signals of different wavelengths at the transmitting end and separates these signals at the receiving end to restore the original signal. Wavelength division multiplexers can be divided into several types, such as branch mirror type, interference model and diffraction grating type, according to different splitting principles. Most of the products on the market are diffraction grating type. Wavelength division multiplexing technology is widely used, including but not limited to telecommunications, cable television, national defense communications and other fields. For optical cables that have been laid, wavelength division multiplexing technology can also be used to achieve multi-channel transmission, which plays a role in reducing costs and expanding capacity.

[0062] Working principle: Press the start button on the control panel 1, the assembly machine starts, the staff conveys the electronic components to the multiple groups of feeding barrels 2 through the feeding system, and conveys the substrate to the blanking plate 13 in the blanking line. The substrate is located in the groove of the blanking plate 13. The displacement sensor on the blanking plate 13 feeds back data to the control system. The control system controls the vacuum pump to work. The vacuum pump extracts the air in the cavity 121 (the cavity 121 is located on the blanking plate 13) through the pipeline. The cavity 121 adsorbs the substrate in the groove through the adsorption hole to realize the automatic positioning of the substrate. After the substrate is adsorbed and positioned by the groove on the blanking plate 13, the blanking line drives the substrate forward to the bottom of the horizontal module 18;

[0063] The feeding system places the electronic components on the two groups of rotating plates 21 of the feeding barrel 2. The two groups of rotating plates 21 support the electronic components. The displacement sensors on the rotating plates 21 feed back data to the control system. The control system controls the first spring 211 to be energized. After the first spring 211 is energized, each turn generates a mutually attractive magnetic field. The magnetic field compresses the first spring 211, causing the first spring 211 to shrink as a whole. The first spring 211 pulls the rotating plate 21 to rotate a certain angle, causing one end of the rotating plate 21 located in the feeding barrel 2 to change from a horizontal state to a vertical state. After that, the electronic components fall from the bottom of the feeding barrel 2.

[0064] The electronic components in the feeding barrels 2 above the two groups of feeding lines fall onto the feeding plate 12, and the electronic components are located in the grooves of the feeding plate 12. The displacement sensor on the feeding plate 12 feeds back data to the control system, and the control system extracts the air in the cavity 121 of the feeding plate 12 outward through the vacuum pump and the pipeline. The cavity 121 adsorbs the electronic components in the grooves of the feeding plate 12 through the adsorption holes, thereby realizing the adsorption and positioning of the electronic components.

[0065] After the electronic components are adsorbed and positioned, the displacement sensor on the feed plate 12 feeds back data to the control system, and the control system controls the feed line to drive the feed plate 12 and the electronic components to move forward, so that the electronic components on the feed plate 12 are located at one end of the feed line. The feed line feeds back the displacement data of the feed plate 12 to the control system, and the control system controls the transverse module 18 to drive the longitudinal module 181 to move above one end of the feed line, so that the visual camera 15 is facing the electronic components. The visual camera 15 identifies the electronic components and feeds back the data to the control system, and the control system then determines whether the electronic components are placed correctly;

[0066] When the control system obtains the data of whether the electronic components are placed correctly, the control system controls the horizontal module 18 to drive the longitudinal module 181 to move, and the longitudinal module 181 drives the rotating motor 182 and the fixed plate to follow the movement, so that the adsorption cover 17 on the fixed plate is facing the electronic components. At this time, the control system controls the electromagnetic valve in the second pipe 222 to open, the coil 24 to pass positive phase AC, and the electromagnet 241 on the reciprocating plate B231 to energize according to the displacement data of the horizontal module 18, so that the electromagnet 241 on the reciprocating plate B231 and the positive magnetic field generated by the coil 24 attract each other. Under the action of the attraction, the reciprocating plate B231 moves upward while stretching the spring. The reciprocating plate B231 absorbs the dust on the surface of the electronic components through the adsorption cover 17 through the second pipe 222, and the dust is filtered on the screen. The air passes through the screen and enters the lower side of the liquid storage cylinder 22;

[0067] When the displacement sensor on the reciprocating plate B231 detects that the reciprocating plate B231 moves to the uppermost side, the control system closes the solenoid valve in the second pipe 222, cuts off the power to the coil 24, and passes reverse alternating current, and opens the solenoid valve in the third pipe. The reverse magnetic field generated by the coil 24 and the electromagnet 241 on the reciprocating plate B231 repel each other. Under the action of the repulsive force, the reciprocating plate B231 moves downward and compresses the spring. The reciprocating plate B231 discharges the air on the lower side of the liquid storage cylinder 22 to the outside air through the third pipe. The control system continuously passes positive and reverse alternating currents to the coil 24, so that the reciprocating plate B231 continuously moves up and down, so that the adsorption hood 17 continuously adsorbs and filters the dust.

[0068] After the electronic components on the feeding line are adsorbed and dusted, the control system turns off the power of the electromagnet 241 on the reciprocating plate B231 and opens the solenoid valve in the third pipe, and then turns off the power of the coil 24 and passes the positive phase alternating current, turns on the electromagnet 241 on the reciprocating plate A23 and opens the solenoid valve in the first pipe 221. The positive magnetic field generated by the coil 24 and the electromagnet 241 on the reciprocating plate A23 repel each other. Under the action of the repulsive force, the reciprocating plate A23 moves upward and compresses the spring. The reciprocating plate A23 transports the glue from the upper side of the liquid storage cylinder 22 through the first pipe 221 to the glue dispensing cylinder 16. The electric cylinder B25 drives the glue dispensing cylinder 16 to slide on the support plate 19. While sliding, the glue dispensing cylinder 16 sprays the glue on the position of the substrate where the electronic components need to be mounted.

[0069] After the glue is sprayed on the substrate, the control system drives the longitudinal module 181 and the rotary motor 182 to move through the transverse module 18, and the rotary motor 182 drives the placement head 14 to move to just above the electronic components through the fixed plate. Then, the longitudinal module 181 drives the rotary motor 182 to move downward, and the rotary motor 182 drives the placement head 14 to move downward to clamp the electronic components.

[0070] When the electronic components are placed correctly, the rotating motor 182 does not rotate. When the electronic components are not placed correctly, the rotating motor 182 drives the electronic components to rotate a certain angle through the mounting head 14 according to the data of the visual camera 15, so that the electronic components are in the correct placement state. After that, the longitudinal module 181 drives the correctly placed electronic components to move upward, and the transverse module 18 further drives the longitudinal module 181, the fixed plate, the mounting head 14 and the electronic components to one end of the unloading line. The longitudinal module 181 drives the mounting head 14 and the electronic components to move downward through the fixed plate and the rotating motor 182, and mounts the electronic components on the substrate position with glue through the mounting head 14, so that the electronic components are bonded to the substrate through the glue, and the assembly of the wavelength division multiplexer is completed. The mounting head 14 is a prior art and can clamp and mount electronic components.

[0071] When electronic components are mounted on the substrate, the mounting head 14 feeds back the pressure data to the control system, and the mounting head 14 releases the electronic components. The control system controls the longitudinal module 181 to drive the fixing plate and the mounting head 14 to move upward. After that, the blanking line drives the blanking plate 13 and the assembled wavelength division multiplexer to be transported forward to the bottom of the ultraviolet light source 26. The ultraviolet light source 26 irradiates the glue with ultraviolet light to solidify the glue. After the ultraviolet light source 26 irradiates for a set time, the blanking line continues to drive the assembled wavelength division multiplexer to move forward until the assembled wavelength division multiplexer moves to the end of the blanking line. At this time, the control system cooperates with the vacuum pump and the pipeline to make the cavity 121 in the blanking plate 13 (the blanking plate 13 near the end of the blanking line) in a normal pressure state, and the adsorption hole cannot adsorb the wavelength division multiplexer. The staff removes the assembled wavelength division multiplexer.

[0072] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
