Abstract

The invention discloses a depth control milling compensation depth detection mechanism and a circuit board depth control milling device. The depth control milling compensation depth detection mechanism comprises a linear driving part, a length gauge, a length gauge mounting part, a presser foot mechanism and a spring, the linear driving part can drive the length gauge mounting part to do linear reciprocating motion, the length gauge mounting part comprises an abutting part; the length gauge is installed on the length gauge mounting part, the presser foot mechanism is in sliding fit with the length gauge mounting part and is arranged opposite to the abutting part, the presser foot mechanism is provided with a channel; and the spring is arranged between the abutting part and the presser footmechanism, one end of the spring is abutted with the abutting part, the other end of the spring is connected or abutted with the presser foot mechanism, the probe end of the length gauge sequentiallypenetrates through the abutting part, the spring and the channel, the probe end face of the length gauge retracts into the channel by a preset distance, and the telescoping direction of the spring, the axis direction of the channel and the linear reciprocating motion direction of the length meter mounting part are parallel. According to the depth control milling compensation depth detection mechanism and the circuit board depth control milling device, presser foot force can be adjusted through the spring so as to be suitable for soft boards and hard boards, and the detection precision of depth control milling compensation depth is improved.

Description

technical field [0001] The invention relates to the field of circuit board processing equipment, in particular to a controlled depth milling compensation depth detection mechanism and a circuit board controlled deep milling device. Background technique [0002] At present, 5G (fifth-generation mobile communication technology) is leading the trend of the Internet of Everything. In the next three to five years, 5G communication will surpass today's two major application markets of smart terminals and automotive electronics, and become the first engine driving the growth of the circuit board industry. However, 5G also puts forward stricter manufacturing process requirements for the production of circuit boards. The typical production process of circuit boards is: blanking→inner layer making→pressing→drilling→copper plating→outer layer making→solder resist printing→text printing→surface treatment→shape processing. Since some products need to install some components into the cir...

Problems solved by technology

When measuring the compensation depth of controlled depth milling, if the pressure of the presser foot is too large, the circuit board will be deformed; if the pressure of the presser foot is too small, the possible warping deformation of the circuit board itself cannot be corrected, and the control of deep milling of the circuit board cannot be guaranteed.
