Problems solved by technology

The finished printed circuit board needs to be cut to a certain size, and burrs are easily generated during the cutting process. If the burrs cannot be removed in a timely and effective manner, it is easy to cause defective products, and it will scratch the skin of the operator and cause work-related injuries.
[0003] In the prior art, the method used to remove the burrs on the printed circuit board is to manually polish one by one, which is extremely inefficient; colleagues must also wear anti-scratch gloves, which brings inconvenience to the operation

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] Such as figure 1 As shown, a plurality of grinding heads for printed circuit boards include a main shaft frame and a main shaft 13. The main shaft frame includes frame plates 1 at left and right ends, and a through hole 2 is provided at the central position of the frame plate. A number of evenly arranged grinding wheels 3 are installed on the main shaft, and the two ends of the main shaft are in clearance fit with the through hole; waist-shaped holes 4 are arranged on both sides of the through hole, and two roller shafts 6 are also included. The roller 7 that rotates with it is installed on it, and the two ends of the roller shaft can move up and down in the said waist hole, and an elastic member 8 is installed between the top of the waist hole and the roller shaft. The elastic member is a spring.

Abstract

The invention discloses a multi-strip polishing machine head of a printed circuit board. The multi-strip polishing machine head comprises a main shaft frame and a main shaft; the main shaft frame includes frame plates at the left and right ends; through holes are formed in the center positions of the frame plates; multiple grinding wheels are uniformly mounted on the main shaft; the two ends of the main shaft are in clearance fit with the through holes; and kidney-shaped holes are formed in two sides of the through holes. The multi-strip polishing machine head further comprises two roller shafts; the roller shafts are provided with rollers rotationally matched with the roller shafts; the two ends of the roller shafts can move up and down in the kidney-shaped holes; and elastic pieces are mounted between the upper sides of the kidney-shaped holes and the roller shafts. The rollers can realize up-down floating relative to the machined printed circuit board, and can adapt to printed circuit boards with different thicknesses and uneven surfaces.

Description

technical field [0001] The invention relates to a multi-strip grinding machine head for printed circuit boards. Background technique [0002] Printed circuit boards are widely used in the electronics industry. The finished printed circuit board needs to be cut to a certain size, and burrs are easily generated during the cutting process. If the burrs cannot be removed in a timely and effective manner, it is easy to cause defective products, and scratch the skin of the operator, causing work injuries. [0003] In the prior art, the method used to remove the burrs on the printed circuit board is to polish them one by one by hand, which is very inefficient; the operator must also wear anti-scratch gloves, which brings inconvenience to the operation. Contents of the invention [0004] In order to solve the technical problems in the prior art described above, the present invention proposes the following technical solutions: [0005] A kind of grinding machine head of a kind of...
