Abstract

The invention discloses an anti-scratching scraper for a circuit board. The anti-scratching scraper comprises a rack (2), a scraper (4) and a circuit board (6), wherein the scraper (4) is fixed on the rack (2) and can be lifted up and lowered through a power device; the circuit board (6) is arranged right below the scraper (4); the anti-scratching scraper is characterized by further comprising an extending end (8) and a control device (10); the control device (10) comprises a first connecting plate (12) and a second connecting plate (14) which are horizontally fixed on a side surface of the circuit board (6). According to the anti-scratching scraper, when the scraper (4) moves downwards to a set value, the sum of the generated pressure and the attraction force acting on a fixing block (18) generated by a magnet (20) is greater than the deformation resistance of a spring (16), then the fixing block (18) can be adsorbed on the magnet (20), moreover, a contact switch is in contact with the magnet (20) so as to control the power device to stop operation, therefore, the scraper (4) can be in direct and sufficient contact with the circuit board (6), a printing effect can be ensured, the circuit board (6) can be prevented from being crushed under compression, and problems of the prior art can be solved.

Description

technical field

[0001] The invention relates to an anti-scratch scraper. Background technique

[0002] In the process of circuit board printing in the prior art, the working process of the scraper is relatively important. There are some problems with the current printing machine scraper: when the circuit board printing machine is working, the scraper descends directly in one stage. The device is directly lowered to the working area, but the current lowering method has the following problems. Because the circuit board that the scraper works on has high requirements for working accuracy, the current method of directly lowering the scraper has low precision and is easy to cause damage to the circuit board. Damage, not easy to produce needs. Contents of the invention

[0003] The purpose of the present invention is to provide a scraper system which can prevent the circuit board from being scratched and ensure the printing effect.

[0004] In order to solve the above problems...
