A pusher for circuit board processing relates to the technical field of circuit board processing and comprises a pushing head, the inner wall of the pushing head is provided with a feeding cavity, the inner top wall of the pushing head is fixedly connected with a first spring, the bottom of the first spring is fixedly connected with a top block, the middle of the top block is fixedly connected with a magnetic block, the inner wall of the pushing head is fixedly connected with a first friction ring, a tooth block is movably connected with the inner wall, close to the outer side of the first friction ring, of the pushing head, a second friction ring is fixedly connected with the inner wall of the tooth block, an air groove is formed in the bottom of the pushing head, and a second spring is fixedly connected with the inner top wall of the air groove. According to the pusher for circuit board processing, through cooperative use of an ejector block and an electromagnet, when the pushing head is blocked, the electromagnet is in a power-on state, and the ejector block can extend downwards under the magnetic attraction action of the electromagnet and a magnetic block to extrude out solid raw materials in the pushing head, so that the effect of automatic cleaning is achieved, time is saved, and the production efficiency is effectively improved.
