Technical Field

[0001] The utility model relates to the technical field of patches, and in particular to a multifunctional precision attaching air pressure device. Background Art

[0002] The pneumatic placement device, used for high-speed, high-precision, fully automated placement of components, is the most critical and complex piece of equipment in the entire SMT production process. It is a key component of the SMT production line, evolving towards multifunctionality, flexible connectivity, and modularity. Its structure is relatively complex, with the PCB placed on an XV movable table, the feeder mounted on a single-axis moving guide rail, and the placement head mounted on a cam turret. This minimizes the distance between picking up components from the feeder and placing them on the PCB, enabling truly high-speed placement.

[0003] A Chinese patent discloses a sticker adsorption device with publication number CN203126101U.

The sticker adsorption device includes an air pressure device and a suction cup; the air pressure device forms an air bag chamber; the suction cup includes at least one hole, and the at least one hole is connected to the air bag chamber, so that a negative pressure suction force is generated through the volume change of the air bag chamber, and the suction cup adsorbs the sticker by the negative pressure suction force to separate the sticker from the release paper." The device achieves negative pressure adsorption of the sticker through the contraction of the air bag chamber. Since the adsorption device can only perform adsorption and cannot remove dust from the surface of the object while adsorbing, the scope of application of the overall attachment air pressure device is reduced.

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 、 Figure 2 、 Figure 3 as well as Figure 4 This embodiment proposes a multifunctional precision attaching air pressure device, including a suction head 1, the top of the suction head 1 is connected to a negative pressure sensor 2 for monitoring air pressure, the top of the negative pressure sensor 2 is connected to a main pipe 3 for air transmission, and the main pipe 3 is connected to a secondary pipe 4 for air transmission. A dust cover 5 for dust removal is fixedly installed on the outside of the suction head 1, and multiple dust removal pipes 51 are fixedly installed on the inner side wall of the dust cover 5. A dust removal component 6 for dust removal and filtration is provided between the secondary pipe 4 and the dust removal pipe 51. The suction head 1 adsorbs the display screen through the action of the main pipe 3. In the process of the main pipe 3 adsorbing part of the airflow of the suction head 1, The negative pressure sensor 2 can monitor the adsorption pressure to prevent the suction head 1 from causing damage to the display screen. While the main pipe 3 is adsorbing, the air can be simultaneously acted on through the surrounding auxiliary pipes 4, so that the four dust removal pipes 51 inside the dust removal cover 5 can adsorb dust on the surface of the display screen and transport it to the dust removal component 6 through the dust removal pipes 51. The dust contained in the air is filtered and then flows into the main pipe 3. When the main pipe 3 stops acting on the airflow, the dust removal component 6 also closes and seals the auxiliary pipes 4, thereby achieving the functionality of dust removal on the display screen and improving the applicability of the device.

[0025] See also Figure 3 、 Figure 4 as well as Figure 5This embodiment proposes a multifunctional precision attaching air pressure device. The dust removal component 6 includes a partition cover 61 connected between the auxiliary pipeline 4 and the dust removal pipe 51. The interior of the partition cover 61 is rotatably connected to the drive shaft 62. The dust removal component 6 includes three sealing plates 63 fixedly installed on the outside of the drive shaft 62. A filter plate 64 is also fixedly installed on the outside of the drive shaft 62. A drive motor 7 is fixedly installed on the outside of the partition cover 61. The output end of the drive motor 7 is fixedly connected to one end of the drive shaft 62. The top of the partition cover 61 is provided with an exhaust port for ventilation. 8. A dust cover 52 is fixedly installed on the outside of the bottom end of the dust removal pipe 51. The dust cover 52 is conical. When there is gas flowing in the main pipe 3, the driving motor 7 can drive the driving shaft 62 to rotate inside the partition cover 61, so that the driving shaft 62 can drive the sealing plate 63 and the filter plate 64 to rotate inside the partition cover 61. When the dust on the surface of the display screen is extracted through the dust removal pipe 51, the filter plate 64 is in a vertical state at this time, and the two sealing plates 63 are in a horizontal state. The partition cover 61 can be cleaned by the action of the two sealing plates 63. The top of the dust removal pipe 51 is closed and sealed. At this time, the airflow inside the dust removal pipe 51 can be filtered through the filter plate 64 and then enter the main pipe 3, thereby achieving the effect of dust removal on the surface of the adsorbed items. When the negative pressure of the suction head 1 reaches the standard, the drive motor 7 can also be used to drive the rotation of the drive shaft 62, so that the drive shaft 62 drives the sealing plate 63 and the filter plate 64 to rotate. The two sealing plates 63 are rotated to a vertical state, and the connecting part between the partition cover 61 and the auxiliary pipe 4 is closed. The dust accumulation position of the filter plate 64 is upward, and the dust will not be blown toward the display screen position when there is airflow inside the dust removal pipe 51, thereby improving the cleaning effect of the overall negative pressure adsorption device on the items to be adsorbed. While the dust removal pipe 51 adsorbs dust, the dust hood 52 at its bottom end can effectively increase the adsorption range of the dust removal pipe 51, thereby effectively improving the cleaning effect of the items to be adsorbed. A patch seat 9 is fixedly installed on the outside of the top of the main pipe 3. The patch seat 9 is used to drive the overall adsorption device to move. The top opening of the dust removal pipe 51 is smaller than the bottom opening.

[0026] In this embodiment, when in use, the main pipe 3 acts on the suction head 1 part, and the negative pressure sensor 2 senses the pressure of the suction head 1 when automatically pasting the patch, thereby effectively preventing the suction head 1 from crushing the display screen patch, ensuring the product qualification rate. When there is airflow passing through the main pipe 3, the partition cover 61 is driven by the driving motor 7 to drive the driving shaft 62, so that the driving shaft 62 can drive the sealing plate 63 and the filter plate 64 to rotate their positions. The sealing plate 63 rotates to a horizontal state to seal the top of the partition cover 61 and the external connection part, and the filter plate 64 rotates to a vertical state. The main pipe 3 is connected The connected secondary pipe 4 allows the suction head 1 to adsorb the dust on the display screen through the dust removal pipe 51 when negative pressure is applied. When the dust flows to the position of the partition cover 61, it can be filtered through the filter plate 64 at this position and then transported to the inside of the main pipe 3, thereby enabling the dust removal function of the suction head 1 to improve the applicability of the overall attached air pressure device. When the negative pressure inside the main pipe 3 is closed, the filter plate 64 and the sealing plate 63 inside the partition cover 61 rotate, so that the sealing plate 63 closes the part of the secondary pipe 4 that is connected to the main pipe 3, thereby allowing the negative pressure device to maintain the suction operation of the suction head 1 on the display screen.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
