Description

Spacing assembly welding frock of wave filter PCBA guide pin Technical Field The utility model belongs to the technical field of filter assembly welding, and particularly relates to a filter PCBA guide pin limiting assembly welding application. Background In the assembly welding process of the filter, a fixture is needed to limit and fix the guide pin, and then the PCBA plate is horizontally inserted into the welding end of the guide pin, so that the guide pin is vertical to the PCBA plate after welding is finished. The technology personnel use traditional PCB bare board processing to make out assembly welding frock and use, but because of the pin pilot hole exists the error, lead to the fact pin and PCBA board welding to accomplish the back appearance tilting phenomenon, need operating personnel to do the reworking to the pin of slope, once qualification rate is lower, consumes a large amount of man-hours. In summary, there is a need to study an assembly welding tool which is easy to weld and position and has high efficiency. Disclosure of utility model The utility model aims to provide a limit assembly welding tool for a PCBA (printed Circuit Board Assembly) guide pin of a filter, which solves the problems that the traditional assembly welding of the PCBA guide pin of the filter is difficult to position and has low efficiency. The technical scheme for solving the assembly welding problem is as follows: a filter PCBA guide pin limiting assembly welding tool comprises a columnar tool main body, wherein the upper surface of the tool main body is a tool welding surface; The fixture welding surface is provided with a groove body in a milling mode, 2 first pin inserting through holes are symmetrically formed in the left end of the groove body in the length direction in an up-down mode, 3 second pin inserting through holes are uniformly formed in the right end of the groove body in the length direction from top to bottom, and the first pin inserting through holes and the second pin inserting through holes are circular through holes and are the same in size; One end of the 5 guide pins to be assembled is provided with a limiting round table, and the 5 guide pins are ensured to vertically penetrate into the first guide pin inserting through hole and the second guide pin inserting through hole respectively and then are limited on the upper surfaces of the first guide pin inserting through hole and the second guide pin inserting through hole, so that the ends of the guide pins to be welded are ensured to be vertically arranged on the welding surface of the tool; The appearance of the PCBA to be assembled is slightly smaller than a tool welding surface, 4 first welding spots are arranged on the upper side and the lower side of a first component welded on the PCBA, two second components welded on the right side of the first component are arranged on the upper side and the lower side of the first component, 4 second welding spots are arranged on the two ends of the first component, the second component, the first welding spots and the second welding spots are suspended in a groove body, the PCBA can be stably placed on the tool welding surface horizontally, the ends of 5 pins to be welded vertically extend out of 5 pin inserting through holes to be welded on the PCBA, and the positions of the 5 pin inserting through holes to be welded correspond to the positions of 2 first pin inserting through holes and 3 second pin inserting through holes one by one. The utility model also comprises the following other technical schemes: The appearance specification of the tool main body is 28 multiplied by 20 multiplied by 21mm, the size of the welding surface of the tool is 28mm multiplied by 20mm, and the size of the groove body is 17.4mm multiplied by 16.5mm multiplied by 4mm.
