Problems solved by technology

[0005] However, the placement machine prepares a vacuum through an air compressor and a vacuum pump. The vacuum generation method consumes a lot of air, and the load of the vacuum pump is also large, so it has the disadvantage of large power consumption; When it is destroyed, the degree of vacuum damage to the entire pipeline is relatively large, and the speed of destruction is relatively slow

Embodiment 1

[0042] This embodiment provides a pneumatic system device suitable for a single suction nozzle, such as figure 1As shown, it includes a suction nozzle air seat 100, a vacuum device and a gas press-in device. Wherein, the vacuum pumping device and the gas pressing device are not marked in the accompanying drawings. 1 suction nozzle 200 , 1 intake channel 300 and 1 vacuum channel 400 .

[0043] A first through hole 110 is provided between the left and right sides of the suction nozzle seat 100 . Both ends of the first through hole 110 are sealed. The two ends of the first through hole 110 are sealed with sealing plugs, in this embodiment, rubber plugs are used.

[0044] An installation channel 120 , an air intake channel 130 and a vacuum channel 140 are also provided in the nozzle air seat 100 . The installation channel 120 , the air intake channel 130 and the vacuum channel 140 are all open channels at both ends; and the first through hole 110 , the installation channel 120...

Embodiment 2

[0052] This embodiment provides a pneumatic system device with multiple first through holes, such as figure 2 and image 3 As shown, it includes a suction nozzle air seat 100, a vacuum device and a gas press-in device. Wherein, the vacuum pumping device and the gas pressing device are not marked in the figure.

[0053] A plurality of first through holes 110 located on the same horizontal plane and parallel to each other are disposed in the nozzle air seat 100 . Both ends of the plurality of first through holes 110 are sealed. In this embodiment, both ends of the first through hole 110 are sealed with rubber stoppers.

[0054] Each of the first through holes 110 communicates with a plurality of installation channels 120 , a plurality of intake channels 130 and a plurality of vacuum channels 140 . The installation channel 120 , the intake channel 130 and the vacuum channel 140 are perpendicular to the first through hole 110 . One installation passage 110 corresponds to one...

Embodiment 3

[0061] This embodiment provides a pneumatic system device with a plurality of first through holes, its main structure is similar to that of Embodiment 2, including a suction nozzle air seat 100, a vacuuming device and a gas pressing device. The connection mode of the nozzle air seat 100, including the suction nozzle air seat 100, the vacuum device and the gas pressure injection device is the same as that of the second embodiment. However, in this embodiment, the purpose of preventing the backflow of the gas is achieved by setting the gas guide switching rod. Specific as Figure 7 and 8 shown.

[0062] A plurality of first through holes 110 and second through holes 150 located on the same horizontal plane and parallel to each other are disposed in the nozzle air seat 100 . Both ends of the plurality of first through holes 110 are sealed. The numbers of the first through holes 110 and the second through holes 150 are the same. The first through hole 110 and the second throu...

Abstract

The invention provides a pneumatic system device which comprises a nozzle air seat, an evacuation device and a gas pressing device. A first through hole, a mounting channel, an inlet channel and a vacuum channel are arranged in the nozzle air seat. A nozzle is arranged on the mounting channel between the first through hole and the bottom of the nozzle air seat. The inlet channel and the vacuum channel are located between the first through hole and the top of the nozzle air seat. The mounting channel, the inlet channel and the vacuum channel are communicated through the first through hole. An opening, which is in the first through hole, of the mounting channel is conical. An opening, which is in the first through hole, of the corresponding inlet channel is inverted conical. According to the invention, when gas is pressed, vacuum destruction is carried out only on one end, which sucks an electronic component, of the nozzle; the vacuum destruction speed of the nozzle is fast; and the pneumatic system device is applicable to a number of mounting channels (a number of nozzles) which are prevented from mutual interference due to a Venturi effect when gas is pressed.

Description

technical field [0001] The invention relates to the technical field of electronic placement, in particular to a pneumatic system device for a placement head. Background technique [0002] The placement machine is an important equipment in the SMT (Surface Mount Technology, surface mount technology) assembly line, and it is also the most costly and demanding equipment in the SMT production line. With the development of the electronics industry, the mounting requirements for PCB (Printed Circuit Board, printed circuit board) in the SMT process are getting higher and higher, and the requirements for placement machines are also getting higher and higher, not only high speed and high efficiency; but also High placement accuracy is required. The efficiency of the placement machine determines the working efficiency of the entire production line, and the placement head is the most critical component on the placement machine, so the placement head directly affects the speed and accu...
