Description

Technical Field

[0001] The utility model belongs to the field of circuit board processing lines, in particular to a clamping frame for circuit board processing lines. Background Art

[0002] Printed circuit boards are providers of electrical connections for electronic components. The use of printed circuit boards can greatly reduce wiring and assembly errors, improve the level of automation and production labor rate. Insulating boards are used as substrates and cut into certain sizes. At least one conductive pattern is attached to them, and holes are arranged on them. They are used to replace the chassis for installing electronic components in the past and realize the interconnection between electronic components. During the processing of printed circuit boards, they need to go through processes such as electroplating. When electroplating circuit boards, electroplating gantry lines are mostly used for automatic lifting and plating. Workers only need to load and remove circuit boards at the clamping location. However, when the prior art is used, the clamps of the clamping frame are mostly assembled by locking upper and lower screws. When the clamps are damaged and need to be replaced or adjusted for clamping, the upper and lower screws need to be unlocked, which is relatively cumbersome. At the same time, the spacing between the clamps is mostly adjusted by estimation or measurement with a ruler before assembly, which is relatively inconvenient. Utility Model Content
