Specific embodiments

[0027] The following combines the accompanying drawings and embodiments to further describe in detail the specific embodiments of the present utility model. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0028] Such as Figures 1 to 5As shown in the figure, a pick-and-place nozzle for a pick-and-place machine includes a nozzle body 1, an air suction cylinder 4, a spiral dust-proof filter element 2, and a pipe connection head 3. Among them, the nozzle body 1, as the part that directly contacts and picks up electronic components, is preferably made of high-strength and wear-resistant materials such as stainless steel to ensure good shape and accuracy during high-speed and frequent operations. The lower end of the air suction cylinder 4 is connected to the upper end of the nozzle body 1; the purpose of the air suction cylinder 4 is to transfer the negative pressure generated inside the nozzle body 1 to the outside to form an adsorption force on the electronic components. The spiral dust-proof filter element 2 is embedded in the inner cavity of the air suction cylinder 4; the lower end of the spiral dust-proof filter element 2 is communicated with the air suction cylinder 4. The spiral dust-proof filter element 2 has a large filtration area and excellent dust interception ability, and can effectively block impurities such as dust and particles in the air from entering the nozzle interior, thereby maintaining the stability and durability of the suction force. Its spiral structure design increases the turbulence of the air flow and improves the filtration efficiency. Preferably, the spiral dust-proof filter element 2 is made of fiber material. The fiber material can be synthetic fiber, such as polypropylene fiber, etc. The lower end of the pipe connection head 3 is connected to the upper end of the air suction cylinder 4 and presses the upper end of the spiral dust-proof filter element 2; the upper end of the spiral dust-proof filter element 2 is communicated with the pipe connection head 3. The pipe connection head 3 is located at the upper end of the air suction cylinder 4. Its design not only facilitates the connection with an external air source, but also presses the upper end of the spiral dust-proof filter element 2 through its structure to ensure the stability of the filter element installation and prevent air leakage. At the same time, this connection head also plays a certain sealing role to prevent external impurities from entering from the interface. Specifically, the upper end of the pipe connection head 3 has a connection pipe portion 32; the connection pipe portion 32 can be a threaded connection pipe portion 32. A sealing ring 5 is sleeved on the connection pipe portion 32 to prevent external impurities from entering from the interface.

[0029] By combining the nozzle body 1, the air suction cylinder 4, the spiral dust-proof filter element 2, and the pipe connection head 3, a spiral dust-proof filter element 2 is embedded in the inner cavity of the air suction cylinder 4 of this pick-and-place nozzle for a pick-and-place machine. The spiral path of the spiral dust-proof filter element 2 extends the air flow channel, effectively increasing the contact area between dust, particles and other impurities and the filter element material, and then greatly increasing the filtration area and improving the filtration efficiency. This design breaks the limitation of the air flow passing straight through the existing filter element, effectively reducing the problem of suction force decline caused by inhaling impurities, and improving the stability and accuracy of pick-and-place.

[0030] Preferably, the spiral dust-proof filter element 2 includes a lower straight pipe section 21, a spiral filter pipe section 22, a filter net 23, and an upper straight pipe section 24 that are connected in sequence from bottom to top and communicate with each other; the lower end of the lower straight pipe section 21 is detachably connected to the lower end of the air suction cylinder body 4 and communicates with the air suction cylinder body 4; the upper end of the upper straight pipe section 24 is detachably connected to the pipe body connector 3 and communicates with the pipe body connector 3. By adopting the connection method from bottom to top, the lower straight pipe section 21, the spiral filter pipe section 22, the filter net 23, and the upper straight pipe section 24 are connected together in sequence. Designing the spiral dust-proof filter element 2 in this way facilitates the installation of the structure, stably installs and is detachably connected to the lower end of the air suction cylinder body 4 and the pipe body connector 3, which is convenient for disassembly, maintenance, and replacement. At the same time, the spiral filter pipe section 22 extends the air flow channel, effectively increasing the contact area between dust, particles, and other impurities and the filter element material, thereby greatly increasing the filtration area, improving the filtration efficiency, and the filter net 23 further enhances the filtration efficiency of the spiral dust-proof filter element 2.

[0031] Specifically, the spiral filter pipe section 22 includes a filter pipe body 221 and a spiral plate 222; the spiral plate 222 is fitted and installed in the filter pipe body 221 in a matching manner; the spiral plate 222 and the inner wall of the filter pipe body 221 form a spiral flow channel 223. By providing the filter pipe body 221 and the spiral plate 222 to form the spiral filter pipe section 22, the spiral plate 222 and the inner wall of the filter pipe body 221 form a spiral flow channel 223. Such a spiral flow channel 223 can effectively increase the contact area between dust, particles, and other impurities and the filter element material, thereby greatly increasing the filtration area, improving the filtration efficiency, and the filter net 23 further enhances the filtration efficiency of the spiral dust-proof filter element 2.

[0032] Among them, the lower end of the air suction cylinder body 4 has a lower installation groove 41 that communicates with the suction nozzle body 1 and is fitted and connected to the lower straight pipe section 21 in a matching manner; the lower end of the pipe body connector 3 has an upper installation groove 31 that communicates with the upper end of the upper straight pipe section 24 and is fitted and installed with the upper end of the upper straight pipe section 24 in a matching manner. By providing the lower installation groove 41 and the upper installation groove 31, the lower straight pipe section 21 and the upper straight pipe section 24 are respectively fitted and installed in the lower installation groove 41 and the upper installation groove 31. The structure is simple, the disassembly and assembly are convenient, and the spiral dust-proof filter element 2 is stably installed in the air suction cylinder body 4.

[0033] To further enhance the stability of the spiral dust-proof filter element 2 in the air suction cylinder body 4 and prevent the structure from shaking or shifting to affect the adsorption of electronic components. A positioning bracket that is fitted and installed with the inner cavity of the air suction cylinder body 4 is provided on the outer side of the spiral dust-proof filter element 2. The design of the positioning bracket further enhances the connection stability between the spiral dust-proof filter element 2 and the air suction cylinder body 4.

[0034] In order to facilitate the disassembly and assembly of the nozzle of the mounter, so as to facilitate later replacement and maintenance, the upper end of the nozzle body 1 is threadedly connected to the lower end of the suction cylinder body 4; the lower end of the pipe connector 3 is threadedly connected to the upper end of the suction cylinder body 4. Through the threaded connection method, the connection of the nozzle body 1, the suction cylinder body 4 and the pipe connector 3 is realized, with a simple structure, convenient disassembly and assembly, and convenient later replacement and maintenance.

[0035] In summary, the embodiment of the present utility model provides a nozzle for a mounter. Among them, the nozzle for the mounter combines the nozzle body 1, the suction cylinder body 4, the spiral dust-proof filter element 2 and the pipe connector 3. A spiral dust-proof filter element 2 is installed in the inner cavity of the suction cylinder body 4. The spiral path of the spiral dust-proof filter element 2 extends the air flow channel, effectively increasing the contact area between dust, particles and other impurities and the filter element material, and then greatly increasing the filtration area and improving the filtration efficiency. This design breaks the limitation of the air flow passing straight through the existing filter element, effectively reducing the problem of suction reduction caused by inhaling impurities and improving the stability and accuracy of the mounting.

[0036] The above are only the preferred embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present application, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present application.
