DETAILED DESCRIPTION

[0020] The following will be described in detail in combination with the accompanying drawings. Figures 1-3 The application is further described in detail.

[0021] The embodiment of the application discloses a deep cavity welding cleaver wire feeding welding device.

[0022] Referring to Figure 1 and Figure 2 , the deep cavity welding cleaver wire feeding welding device comprises a mounting frame 1 arranged on a bonder, a mounting column 2 connected to the mounting frame 1, a mounting hole 19 with a size matched with the cleaver 3 arranged on the mounting column 2, and the cleaver 3 inserted into the mounting hole 19. An operator can detach the cleaver 3 from the mounting column 2 in a plug-in and plug-out mode, so that the cleaver 3 is detachably connected. A plurality of wire feeding holes 4 are arranged on the cleaver 3, and a plurality of wire feeding mechanisms for feeding the wire 6 to the wire feeding holes 4 of the cleaver 3 are arranged on the mounting frame 1. The number of the wire feeding mechanisms is consistent with the number of the wire feeding holes 4. In the embodiment of the application, three wire feeding holes 4 and three wire feeding mechanisms are taken as an example for description.

[0023] Referring to Figure 1 and Figure 2 , the end of the mounting column 2 away from the mounting frame 1 is provided with a top groove 20 communicated with the mounting hole 19, and a jacking bolt matched with the size of the top groove 20 is threadedly connected in the top groove 20. The end of the jacking bolt away from the mounting frame 1 is in contact with the cleaver 3. The jacking bolt limits the position of the cleaver 3 in the mounting hole 19, reduces the possibility of position deviation of the cleaver 3 caused by movement during welding, and improves the stability of the position of the cleaver 3.

[0024] Referring to Figure 2 and Figure 3The cleaver 3 comprises a blade body 8, the end of the blade body 8 away from the wire feeding mechanism is fixedly connected with a blade tip 9, a plurality of wire feeding holes 4 are formed on the blade tip 9, the outer edge of the blade tip 9 is provided with a plurality of avoiding inclined surfaces 18, the avoiding inclined surfaces 18 reduce the occupied space of the blade tip 9 while ensuring the rigidity of the blade tip 9, reduce the possibility of interference between the blade tip 9 and the welding surface or other external components, and facilitate the cleaver 3 to cope with the situation in a narrow space such as deep cavity welding. The blade body 8 is provided with a guide hole 10 communicating with the three wire feeding holes 4, the end face of the blade tip 9 away from the blade body 8 is provided with a first through groove 11 and a second through groove 12, respectively, in the embodiment of the application, the three wire feeding holes 4 communicate with the first through groove 11. Corresponding three guide grooves 17 are formed on the blade tip 9, the three guide grooves 17 are located between the wire feeding holes 4 and the through holes, and the three guide grooves 17 correspond to the three wire feeding holes 4, respectively. The guide groove 17 plays a guiding role for the metal wire 6, facilitating the subsequent smooth insertion of the metal wire 6 into the corresponding wire feeding hole 4, and at the same time, through the separation and positioning of the metal wire 6 by the guide groove 17, the possibility of mutual interference between the metal wires 6 is reduced.

[0025] Referring to Figure 1 and Figure 2 , the three wire feeding mechanisms respectively comprise a supporting column 5 arranged on the mounting frame 1, the outer edge of the supporting column 5 is rotationally connected with a wire feeding reel 7, the metal wire 6 is wound around the outer edge of the wire feeding reel 7, the mounting frame 1 is provided with a supporting unit for supporting the gathered metal wires 6, the three wire feeding reels 7 are arranged in a triangular shape, reducing the occupied space of the three wire feeding reels 7, and improving the space utilization rate. The outer edge of the wire feeding reel 7 is fixedly connected with two blocking rings, the metal wire is located on the inner edge of the two blocking rings, and the two blocking rings limit the position of the metal wire, reducing the possibility of the metal wire deviating from the wire feeding reel 7.

[0026] Referring to Figure 1 and Figure 2 , the supporting unit comprises a supporting rod 13 arranged on the mounting frame 1, in the embodiment of the application, the supporting rod 13 is arranged in a curved manner towards the cleaver 3, the supporting rod 13 is provided with a guide pipe 14, the three metal wires 6 pass through the guide pipe 14, the guide pipe 14 comprises a first guide pipe 15 arranged on the supporting rod 13 and coaxially arranged with the guide hole 10, one end of the first guide pipe 15 away from the cleaver 3 is fixedly connected with a second guide pipe 16 arranged in an inclined manner towards the wire feeding reel 7, the second guide pipe 16 arranged in an inclined manner plays a guiding role for the direction of the metal wire 6, facilitating the smooth insertion of the metal wire 6 into the first guide pipe 15. Therefore, the metal wire 6 sequentially passes through the second guide pipe 16, the first guide pipe 15, the guide hole 10, the guide groove 17, the wire feeding hole 4 from the outer edge of the wire feeding reel 7 and is welded at the end of the blade tip 9 away from the blade body 8, the guide pipe 14 plays a gathering and guiding role for the three metal wires 6, facilitating the smooth passing of the metal wire 6 through the guide hole 10.

[0027] In addition, the wavelength of terahertz frequency is extremely short, so the packaging requirements of the corresponding chip are small pitch and arc end, so as to reduce the parasitic parameters of the wire 6 arc. At the same time, due to the high transmission rate of the silicon photon transmission module, the optical mode transmission optical signal needs to be bonded with equal length and equal height arc, and the consistency between the arcs is required to be high. The traditional cleaver 3 can only pass through one wire, and in the welding process, multiple wires 6 and wires 6 rely on the bonding machine to adjust the arc length and arc height, and the welding consistency is difficult to meet the requirements of terahertz and silicon photon bonding consistency.

[0028] The implementation principle of the embodiment of the present application is that when three wires 6 need to be welded at the same time, the three wires 6 are sequentially threaded through the second conduit 16, the first conduit 15, the guide hole 10, the guide groove 17, the wire feeding hole 4 from the outer edge of the wire feeding reel 7, and finally reach the end of the blade tip 9 away from the blade body 8, so that the cleaver 3 can bond multiple equal length and equal height arcs at one time, meet the requirements of terahertz and silicon photon bonding consistency, save the step of adjusting the arc length multiple times to ensure the welding consistency in the related art, and improve the welding quality and welding efficiency.

[0029] The specific embodiment is only an explanation of the present application, and is not a limitation of the present application. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the present specification, but as long as it is within the scope of the claims of the present application, it is protected by the patent law.
