Problems solved by technology

[0004] However, when the grinding device in the above technology is grinding the side surface of the PCB circuit board, since the grinding structure and the side surface of the circuit board are directly exposed to the external environment, the impurities polished on the circuit board will fly around in a large area. It is difficult to be effectively recovered and cleaned by the pumping structure, which is easy to cause pollution to the processing site

Embodiment 1

[0030] see Figure 1-Figure 4 As shown, a high-frequency and high-speed PCB polishing device with automatic cleaning function described in the embodiment of the present invention includes a support plate 1; two sets of baffle plates 2 are symmetrically connected to the support plate 1, and the support plate 1 is close to The top surface of the baffle plate 2 is symmetrically provided with a slide chamber 3, the top of the slide chamber 3 is slidably connected with a slide plate 4 that fits the inner wall, the top of the slide plate 4 is connected with an elastic layer 5, and the slide plate 4 is connected to the slide plate 4. There is a No. 1 spring connected between the bottom ends of the cavity 3, and a support cavity 6 is connected to the side wall of the baffle plate 2 corresponding to the top side of the sliding cavity 3, and the inside of the support cavity 6 is slidably connected to fit the inner wall. The limiting plate 7, the No. 2 spring is connected between the lim...

Embodiment 2

[0040] Such as Figure 5 As shown in Comparative Example 1, another embodiment of the present invention is: an arc-shaped sleeve 36 is embedded in the nozzle hole, and a gap is opened on the side of the arc-shaped sleeve 36 close to the inner end of the groove. The inside of the arc-shaped sleeve 36 is connected with a cylindrical rotating post 37 through a torsion spring, the side wall of the rotating post 37 fits with the inner wall of the arc-shaped sleeve 36, and the side wall of the rotating post 37 is provided with a gap connected to the air outlet hole 38, the end of the air outlet hole 38 away from the groove is arranged obliquely downward; The pressure will also drive the rotating column 37 to rotate by applying frictional resistance to the rotating column 37, so that the gas inside the groove is ejected in a rotating manner from the rotating air outlet hole 38, thereby increasing the cleaning area of ​​the eardrum 34 for impurities. Further promote the recovery of i...

Abstract

The invention belongs to the technical field of polishing devices, and particularly relates to a high-frequency and high-speed PCB polishing device with an automatic cleaning function. A baffle is connected to the supporting plate, sliding cavities are symmetrically formed in the top face, close to the baffle, of the supporting plate, sliding plates are slidably connected to the top ends of the sliding cavities, supporting cavities are connected to the side walls of the baffle, limiting plates are slidably connected into the supporting cavities, and the inner ends of the sliding cavities communicate with the inner ends of the supporting cavities through air pipes. A first motor is arranged at the bottom end of the supporting cavity, a ball screw is connected to the end of the first motor, a second motor is connected to the ball screw through a sliding table and a connecting plate, a grinding head is connected to the top end of the second motor, and an automatic air exhaust assembly is further arranged on the device. According to the circuit board polishing device, the situation that impurities polished off the side wall of a circuit board fly around can be reduced, pollution to the field environment is reduced, meanwhile, the polished circuit board can be conveniently taken out, and the polishing efficiency of the circuit board is improved.

Description

technical field [0001] The invention belongs to the technical field of grinding devices, in particular to a high-frequency and high-speed PCB grinding device with an automatic cleaning function. Background technique [0002] PCB, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical interconnection of electronic components. The traditional deburring of the side surface of the PCB board is usually manual hand-held grinding, which is inefficient and has a low degree of automation. Some structures can be used for grinding the fixed PCB board, but the grinding effect is not ideal, and the debris generated after grinding is relatively difficult to collect. Troublesome, manual secondary cleaning is required. [0003] A Chinese patent with the publication number CN210790327U discloses a device for deburring the side surface of waste PCB boards, including a workbench, a through hole, a first rota...
