DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0019] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the patch machine rapid air floating suction head device comprises a mounting plate 1, a limiting plate 2 is fixedly installed at the lower side of the upper end of the mounting plate 1, a suction pipe 3 is slidably connected to the upper end of the limiting plate 2, a suction disc 4 is fixedly installed at the lower end of the suction pipe 3, a suction nozzle 5 is fixedly installed at the inner upper end of the suction disc 4, a sleeve 6 is slidably connected to the lower end of the suction nozzle 5, a rubber pad 7 is fixedly installed at the lower end of the sleeve 6, a filter screen 8 is fixedly installed in the rubber pad 7, a clamping groove 9 is formed in the outer side of the sleeve 6, a sliding block 10 is slidably connected to the inner left and right sides of the suction nozzle 5, a spring 11 is arranged between the sliding block 10 and the suction nozzle 5, and a locking block 12 is rotatably connected to the lower end of the sliding block 10.

[0020] The embodiment: when the air floating suction head sucks the electronic components, the suction disc 4 is attached to the electronic components, and then the air pump on the mounting plate 1 is started. The air pump is communicated with the suction pipe 3 through the pipeline. The air pump sucks out the gas in the suction pipe 3. The suction nozzle 5 is communicated between the suction nozzle 5 and the suction pipe 3. The suction nozzle 5 sucks the air in the suction disc 4, so that the negative pressure is formed between the suction disc 4 and the electronic components. The position of the suction nozzle 5 is slightly lower than that of the suction disc 4. When the suction disc 4 sucks the electronic components to a certain extent, the suction nozzle 5 will contact the electronic components and further suck the electronic components. Through the double suction of the suction disc 4 and the suction nozzle 5, the stability of sucking the electronic components is improved, which is convenient for precise installation of the electronic components. The rubber pad 7 is attached to the lower end of the suction nozzle 5, so that the suction nozzle 5 is in flexible contact with the electronic components, avoiding damage to the electronic components caused by rigid contact between the suction nozzle 5 and the electronic components. At the same time, the filter screen 8 filters the air sucked by the suction nozzle 5, avoiding the suction of dust and impurities into the suction nozzle 5 and the suction pipe 3, causing the suction nozzle 5 and the suction pipe 3 to be blocked, affecting the subsequent use of the air floating suction head device. The filter screen 8 needs to be cleaned and replaced after a long time of use. The sleeve 6 is taken off from the outside of the suction nozzle 5, and the filter screen 8 is cleaned and replaced. Then the cleaned and replaced sleeve 6 is sleeved on the outside of the suction nozzle 5, so that the rubber pad 7 is tightly attached to the lower end of the suction nozzle 5. Then pull the sliding block 10 to press the spring 11, pull the locking block 12 on the sliding block 10 to the parallel position of the clamping groove 9, then rotate the locking block 12 to make the locking block 12 clamped into the clamping groove 9, and then release the sliding block 10. The spring 11 is reset to pull the sliding block 10 upward, so as to drive the locking block 12 to slide upward. The locking block 12 is clamped into the clamping groove 9, so as to pull the sleeve 6 upward, so that the rubber pad 7 is tightly attached to the lower end of the suction nozzle 5, facilitating the replacement and cleaning of the filter screen 8, and improving the stability of the sleeve 6 after installation and the tightness between the rubber pad 7 and the suction nozzle 5.

[0021] Referring to Figure 1 , Figure 2 and Figure 3 , in a preferred embodiment, the fixed ring 13 is fixedly installed in the middle of the suction disc 4. The buffer rod 14 is fixedly installed at the lower end of the fixed ring 13. The buffer rod 14 is made of rubber material. The fixed block 15 is fixedly installed at the upper end of the front side of the mounting plate 1. The hydraulic rod 16 is fixedly installed at the lower end of the fixed block 15. The stabilizing plate 17 is fixedly installed at the lower end of the hydraulic rod 16.

[0022] The length of the buffer rod 14 is longer than the suction nozzle 5, and the bottom end plane of the buffer rod 14 is lower than the bottom end plane of the suction disc 4, that is, the bottom horizontal plane of the buffer rod 14 is higher than the bottom horizontal plane of the suction disc 4. When the suction disc 4 sucks the electronic component, the hydraulic rod 16 on the fixed block 15 is started, the hydraulic rod 16 drives the stabilizing plate 17 to slide downward, thereby driving the suction pipe 3 to slide downward, so that the suction disc 4 contacts the electronic component. The suction disc 4 sucks the electronic component, then the buffer rod 14 contacts the electronic component, finally the suction nozzle 5 sucks the electronic component. The buffer rod 14 provides a buffer between the suction nozzle 5 and the electronic component, avoids that the suction nozzle 5 rigidly sucks the electronic component and causes damage to the electronic component, improves the safety of the electronic component during sucking, and after the sucking is completed, the hydraulic rod 16 drives the stabilizing plate 17 to rise, thereby driving the suction pipe 3 to rise, so that the suction disc 4 and the sucked electronic component rise, which is convenient for the electronic component to rise and fall, and is convenient for the electronic component to be installed.

[0023] The above is only a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. According to the technical solution and the inventive concept of the present application, equivalent replacement or change should be covered in the protection scope of the present application.
