In the present embodiment:

the support bosses 1211 are used for providing a support structure for the support plate 1212, the placing plate 1213 and the connecting pieces 1214;

the suction cavity 12111 is used for providing a space of negative pressure for the support boss 1211;

the first fixing groove 12112 is used to provide a space for placing the support plate 1212 and the placing plate 1213;

the second fixing groove 12113 is used to provide a space for the link 1214;

the support plate 1212 is used to provide a supporting structure for the placement plate 1213;

the first pumping hole 12121 is used to provide a passage for the gas adsorbed by the pumping device 3;

the placing plate 1213 is made of rubber material and is used for providing a supporting structure for the circuit board to be processed, and when the circuit board is processed, the placing plate 1213 is a buffer structure for protecting the drill 22, so that the drill 22 is prevented from being damaged due to too large descending stroke during the processing of the drill 22;

the second pumping hole 12131 is used for providing a flow passage for the gas absorbed by the pumping device 3;

the anti-skid groove 12132 is used for increasing the friction force of the circuit board to be processed;

the connecting piece 1214 is used for providing a structure for connecting the suction platform 121 for the air extracting device 3, a plurality of through holes which are arranged in sequence are arranged on the connecting piece 1214, and the through holes are communicated with the air extracting cavity 12111;

specifically, when a worker places a circuit board to be processed, the air exhaust device 3 is started firstly, at the moment, air flow is sucked from the placing platform 12 and discharged to the outside after entering the air exhaust device 3, the circuit board is automatically adsorbed by the sucked air pressure after being placed, and the air exhaust device 3 is closed after the processing is finished, so that the worker can place the circuit board quickly, the fixing time of the circuit board is saved, and the processing efficiency is improved;

when the circuit board is adsorbed, the external air flow flows in from the second air suction hole 12131 on the placing plate 1213, then enters the first air suction hole 12121, then enters the air suction cavity 12111, and finally enters the air extracting device 3 from the air suction cavity 12111, when the worker places the circuit board to be processed on the placing plate 1213, the air flow entering the second air suction hole 12131 presses the circuit board on the placing plate 1213, and at this time, the circuit board covers the second air suction hole 12131 and is also fixed on the placing plate 1213.

Further, the processing and manufacturing equipment for the precise electronic parts comprises a dehumidifying device 6, the dehumidifying device 6 is fixedly connected to the three-axis machine tool 1 and is electrically connected with the control machine table 5, an air outlet 61, a shielding plate 62 and an air suction opening 63 are arranged on the dehumidifying device 6, the air outlet 63 is located above the shielding plate 62, the air suction opening 63 is located below the shielding plate 62, and the air outlet 61 and the air suction opening 63 are both towards the placing platform 12.
