Description

Technical Field

[0001] The utility model relates to the technical field of filter processing and manufacturing, in particular to a hard-lead ultra-small sealed filter manufacturing integrated device. Background Art

[0002] With the development of society, the electronic component industry as a whole shows a trend towards miniaturization. Among them, the ultra-small sealed filter, as a universal micro-frequency selection device, can effectively filter out the frequency point of a specific frequency in the power line or the frequency outside the frequency point, and obtain a power signal of a specific frequency, or eliminate the power signal after a specific frequency. The processing quality of the filter determines the quality of the transmission signal. In order to meet the requirements of the later use environment and enhance the quality reliability of components, the requirements for processing accuracy in batch production are getting higher and higher, and the process control is becoming more and more difficult. Due to the small size of the components involved in the hard-lead ultra-small sealed filter, unlike the traditional straight-lead filter, this type of finished product is required to be directly inserted into the circuit board, which determines that the leads at both ends of the workpiece are vertically bent. Therefore, the process control of this type of workpiece is difficult. During the assembly and welding process, the leads are very likely to be offset, the coaxiality accuracy is not enough, the assembly direction state is inconsistent, and the hard lead is difficult to form. During the lead forming process, the stress causes cracks in the glass beads at the bottom of the workpiece, and the quality inspection fails. In addition, the efficiency of manual inspection of verticality after the lead is bent is low.

[0003] In the prior art, there are some single-function fixtures for welding straight-lead ultra-small sealed filters, which cannot solve the bottleneck problem of integrating the lead bending, assembly welding and potting positioning functions into one. Utility Model Content

[0004] The purpose of the utility model is to provide an integrated device for manufacturing a hard-lead ultra-small sealed filter, which is used to solve the problem that no device in the prior art can meet the requirements of integrating the lead bending, assembly welding and potting positioning functions of the hard-lead ultra-small sealed filter.

DETAILED DESCRIPTION

[0038] The present invention is further described in detail below in conjunction with the embodiments, but the implementation manner of the present invention is not limited thereto.

[0039] Embodiment 1:

[0040] Combined with Figure 1-Figure 10 As shown, a hard lead ultra-small sealed filter manufacturing integrated device comprises:

[0041] An assembly welding tool, the assembly welding tool comprises a cover plate 2, a first positioning plate 3, a second positioning plate 4 and a bottom plate 5, the assembly welding tool also comprises a connecting rod which sequentially penetrates and fixes the bottom plate 5, the second positioning plate 4, the first positioning plate 3 and the cover plate 2, the cover plate 2 is provided with a first groove 21 for fixing the position of the bent lead, the first positioning plate 3 is provided with a second groove 31 for fixing the upper end of the workpiece 7 and for the lower end of the workpiece 7 to pass through, the second positioning plate 4 is provided with a third groove 41 for fixing the lower end of the workpiece 7 and for the lead wire of the lower end of the workpiece 7 to pass through, and the bottom plate 5 is provided with a countersunk hole 51 for fixing the lead wire of the workpiece 7;

[0042] The lead bending tool is used to bend the lead of the workpiece 7.

[0043] Working principle:

[0044] The lead wire at one end of the workpiece 7 is bent by a lead bending tool to form an L-shaped lead wire 66, and the first positioning plate 3, the second positioning plate 4 and the bottom plate 5 are fixed in sequence by connecting rods, and the lead wire at the other end of the workpiece 7 passes through the first positioning plate 3, the second positioning plate 4 and the bottom plate 5 in sequence, and then the cover plate 2 is fixed to the connecting rod, so that the bent end lead wire of the workpiece 7 is located in the first groove 21. The upper end of the workpiece 7 matches the second groove 31 of the first positioning plate 3, the lower end of the workpiece 7 matches the third groove 41 of the second positioning plate 4, and the lower end of the lead wire passes through the countersunk hole 51 of the bottom plate 5. After the workpiece 7 is assembled and welded into a semi-finished product, the lead wire at the other end of the workpiece 7 is bent by a lead bending tool.

[0045] The cover plate 2, the first positioning plate 3, the second positioning plate 4, the bottom plate 5 and the lead bending tool are all provided with multiple different models, and different combinations can meet the lead bending, assembly welding and potting positioning of the same type of filters with different specifications.

[0046] When the present invention is applied, since the leads at both ends of the ultra-small sealed filter are bent, the lead direction and the position of the parts need to be fixed during the assembly process, and the length of the workpiece lead from the parts assembly is certain, and the L-shaped lead 66 is kept perpendicular to one side of the shell of the workpiece. In order to ensure the coaxiality requirements of the lead and the shell, both sides of the lead need to be positioned and clamped, thereby reducing the dimensional deviation of the workpiece, improving the accuracy of the workpiece, and effectively preventing and reducing the deformation of the weldment; the workpiece is placed in the best welding position, the process defects are significantly reduced, and the processing efficiency is improved. It can be seen from the workpiece that the leads at both ends of the workpiece are positioned in parallel with the bottom plate 5 and the cover plate 2, and the middle positioning plate (the first positioning plate 3 and the second positioning plate 4) positions the shell direction. The lower end of the workpiece L-shaped lead 66 is placed on the countersunk hole 51 of the bottom plate 5, and is fixed and welded on the positioning plate of the tooling. After all the workpieces complete the above process, the cover plate 2 is covered, and the upper end (short side) of the workpiece L-shaped lead 66 is placed in the first groove 21 of the cover plate 2 to complete the direction positioning and position tightening, and finally solidify to complete welding and potting. The semi-finished workpiece is then placed on the lead bending tool, and the workpiece is positioned through the circular through hole 61 and the stepped groove to complete the bending of the lead at the other end.
