Description

Technical Field

[0001] The invention relates to the field of assembly tooling, in particular to an assembly tooling for filter PIN pins, and belongs to the technical field of application of assembly tooling for PIN pins. Background Art

[0002] The power filter is a filter circuit composed of capacitors, inductors and resistors. The filter can effectively filter out the frequency point of a specific frequency in the power line or the frequency outside the frequency point to obtain a power signal of a specific frequency, or eliminate a power signal after a specific frequency. The installation of the PIN pin during the filter assembly process is an important factor affecting the assembly quality of the filter. The existing filter PIN pin assembly tooling mostly adopts horizontal installation during assembly. The filter to be assembled is clamped and positioned by a positioning mechanism, and after automatic feeding through a conveyor belt, the PIN pin is pushed horizontally into the assembly position by a pushing mechanism to complete the assembly. As a result, the PIN pin is easily subjected to uneven horizontal thrust during the assembly process, which causes the PIN pin to easily generate torque or dislocation with the connection part of the filter after assembly, thereby causing the filter to be unstable during use.

At the same time, the workpiece to be assembled is horizontally assembled when the PIN pin is not there, avoiding the situation in which the existing assembly tooling generates torque or misalignment with the workpiece due to uneven force on the PIN pin during horizontal assembly, thereby greatly improving the assembly quality and assembly efficiency of the PIN pin.

[0020] 2.

The structure of the plurality of feed slots 211 is adapted to the structure of the workpiece to be assembled, so that when the conveyor belt 206 transports the workpiece to be assembled into the feed slot 211, the limit plate 212 provides a limit for the workpiece to be assembled to prevent the workpiece to be assembled from being moved out of the feed slot 211. By providing the feed tray 210, the workpiece to be assembled is pushed into the feed slot 211 and pushed out by the push rod 208, so that the workpiece to be assembled can change the moving height through the transmission of the feed tray 210, so as to meet the transmission requirements of different types of transmission platforms, and the workpiece is transmitted by the rotation of the feed tray 210, so that the transmission speed of the workpiece can be more accurately adjusted according to the driving speed of the second motor 205 to meet the movement requirements of the moving mechanism 3 for the workpiece to be assembled, thereby improving the assembly efficiency.
