Universal Component Insertion Machine Triangular Positioning Pin (90-Degree Pin/PCB Positioning Block)

I. Basic Product Information

Compatible Models: Universal vertical component insertion machines, mainstream models: 6380B, 6360E, 6241, etc., axial/radial component insertion equipment, original part number C293381565, commonly known in the industry as 90-degree pin or triangular positioning block.

Core Function: A PCB side positioning pin at the insertion station. It uses a cylindrical pin at the top to insert into the PCB process hole, fixing the circuit board coordinates and ensuring component insertion accuracy. The base has multiple adjustable holes to accommodate PCBs of different widths and positioning hole spacings. It is a core, easily damaged component of the component insertion machine.

Material and Manufacturing Process:
Base: Cold-rolled steel sheet, stamped and formed, blackened for rust prevention; Positioning pin: High-carbon steel, hardened by quenching, wear-resistant and not easily deformed, suitable for long-term high-frequency impact positioning on the production line.

II. Complete Specifications (PIN Diameter)

All in-stock specifications shown in the image correspond to the following PCB positioning hole diameters:

2.2mm, 2.5mm, 3.0mm, 3.2mm, 3.5mm, 3.8mm, 4.0mm, 4.2mm, 4.5mm
The base is a uniform five-hole T-shaped triangular structure, with universal mounting hole positions. Only the diameter of the top positioning cylindrical pin differentiates the models.

III. Structural Features

Multi-hole Adjustable Base: 5 horizontal mounting holes allow for fine-tuning of the mounting position, compatible with various fixture tracks;

Integrated Soldered Positioning Pin: The pin is firmly fixed and will not fall off. The spherical end facilitates smooth PCB insertion and removal;

T-shaped Triangular Design: Avoids interference with component insertion path and does not interfere with the movement of the insertion head. 90° vertical positioning prevents board misalignment;

Universal for Left and Right: Single model is not differentiated by left or right, making replacement and installation simple and reducing inventory variety.

IV. Usage and Replacement Instructions

Selection Basis: Measure the inner diameter of the positioning process holes on the side of the PCB board and select a matching diameter PIN; if the hole is misaligned, select a larger pin size to avoid PCB wobbling and misalignment of the components;

Replacement Standards: Wear and thinning of the pin, chipping of the end, deformation, blackening, and cracking of the base will cause batch component misalignment and require immediate replacement;

Installation Method: Screws are passed through the pre-drilled holes in the base and locked to the equipment track fixture. Slight adjustments to the positioning distance are possible.

V. Applicable Industries
Automatic assembly lines for axial capacitors, resistors, and connectors in home appliance PCBs, power supply boards, industrial control circuit boards, charger circuit boards, etc.
