Description

Technical Field

[0001] The utility model relates to the technical field of nozzles for chip placement machines, in particular to a highly wear-resistant manganese-based phosphating nozzle. Background Art

[0002] With the rapid development of electronic manufacturing technology, chip mounters occupy a vital position in the field of electronic production. As one of the key components of chip mounters, the performance of the chip mounter nozzle directly affects the quality and efficiency of the chip placement.

[0003] In the current electronics manufacturing industry, the requirements for the placement accuracy and speed of placement machines are getting higher and higher. However, traditional placement machine nozzles have exposed many problems in actual applications.

[0004] First of all, the wear resistance of ordinary placement machine nozzles is generally insufficient. During frequent placement operations, the nozzles need to constantly contact, absorb and place electronic components, which makes the nozzle surface susceptible to wear. As the use time increases, the degree of wear of the nozzle continues to increase, which not only affects the appearance of the nozzle, but more importantly, it will reduce the suction accuracy and stability of the nozzle. When the wear of the nozzle reaches a certain level, the nozzle needs to be replaced, which not only increases production costs, but also affects production progress.

[0005] Secondly, when the existing placement machine nozzle is damaged, it is often necessary to replace the nozzle as a whole. For example, when the nozzle head is damaged or the spring fails, due to the unreasonable structural design of the nozzle, the damaged parts cannot be replaced separately. The entire nozzle can only be discarded and replaced with a new one. This practice not only wastes resources, but also increases the company's production costs.

[0006] Furthermore, the filter screen provided inside the nozzle is often difficult to be disassembled and assembled conveniently, which makes the replacement or cleaning of the filter screen rather cumbersome. In severe cases, it may even cause the nozzle to be unable to be used normally, resulting in inconvenience in maintenance.

[0007] Therefore, how to provide a highly wear-resistant manganese phosphating suction nozzle is a problem that those skilled in the art urgently need to solve. Utility Model Content

[0008] One purpose of the present invention is to provide a highly wear-resistant manganese phosphating suction nozzle. The present invention can improve the wear resistance of the suction nozzle and extend its service life. The nozzle head, spring and other wearing parts can be easily replaced. When damaged, the entire suction nozzle does not need to be scrapped, which saves costs. It can also facilitate the disassembly and cleaning of the metal filter ring.

[0009] According to an embodiment of the present invention, a highly wear-resistant manganese phosphating nozzle comprises a nozzle body, a telescopic tube, a nozzle head and a metal filter ring;

[0010] A telescopic tube is telescopically installed on the upper part of the nozzle body, a mounting cap is integrally formed at the bottom of the nozzle head, and the mounting cap is detachably mounted on the top of the telescopic tube. A quick connector is integrally formed at the bottom of the nozzle body, and the nozzle head, mounting cap, telescopic tube and quick connector are interconnected. A spring is sleeved on the outside of the telescopic tube, and the spring is arranged between the mounting cap and the nozzle body;

[0011] A threaded joint is integrally formed at the bottom of the mounting cap, a threaded interface is provided inside the top end of the telescopic tube, a support tube is fixedly installed at the bottom of the threaded joint, a magnetic ring is fixedly installed at the bottom of the support tube, an annular groove is provided at the bottom inner side of the threaded interface, and the metal filter ring is placed in the annular groove.

[0012] Furthermore, the nozzle head is processed by manganese phosphating, and a phosphate protective film is formed on the surface of the nozzle head after the manganese phosphating, which greatly improves the wear resistance of the nozzle head and extends its service life.

[0013] Furthermore, the inner and outer diameters of the support tube, magnetic ring, annular groove and metal filter ring are consistent with each other. The metal filter ring can be adsorbed by the magnetic ring, so that when the mounting cap is disassembled, the magnetic ring can drive the adsorbed metal filter ring and the metal filter ring located in the annular groove to be taken out for disassembly, which is convenient for the replacement of the metal filter ring or the cleaning and maintenance of the inner filter screen.

[0014] Furthermore, the outer diameter of the threaded joint corresponds to the inner diameter of the threaded interface, and the outer thread of the threaded joint and the inner thread of the threaded interface engage with each other, thereby ensuring the tightness and stability of the connection between the mounting cap and the telescopic tube.

[0015] Furthermore, a chuck is integrally formed on the outer wall of the nozzle body, and the diameter of the chuck is larger than the nozzle body, which facilitates mechanical clamping operations and increases compatibility with automated machines.

[0016] Furthermore, a filter is fixedly installed inside the metal filter ring, and the mesh number of the filter is 200-500 mesh, which can effectively filter fine dust particles and prevent dust from entering the interior of the suction nozzle and causing blockage.

[0017] Furthermore, a sealing ring is fixedly provided on the top of the telescopic tube to improve the sealing performance, and the outer diameter and inner diameter of the sealing ring are respectively consistent with the outer diameter of the telescopic tube and the inner diameter of the threaded interface, thereby enhancing the sealing performance of the connection between the mounting cap and the telescopic tube.

[0018] The beneficial effects of the utility model are:

[0019] The nozzle head of the utility model is subjected to manganese phosphating treatment to form a phosphate protective film on the surface, which has excellent wear resistance and can maintain good condition during frequent patch operations, greatly improving the service life of the nozzle and reducing the cost of frequent replacement due to nozzle wear. The mounting cap can be engaged with the threaded interface at the top of the telescopic tube through a threaded joint, making installation and removal convenient and quick. When the nozzle head or spring is damaged, it can be quickly replaced without having to discard the entire nozzle, thus saving costs.

[0020] The sealing ring fixed on the top of the telescopic tube effectively prevents air leakage at the connection between the telescopic tube and the mounting cap, ensuring stable suction force and ensuring that electronic components can be stably sucked, thereby improving the accuracy and efficiency of patching.

[0021] Secondly, the support tube and magnetic ring at the bottom of the mounting cap cooperate with the metal filter ring in the annular groove at the bottom inner side of the threaded interface, so that when the mounting cap is removed, the magnetic ring can drive the metal filter ring to be taken out together, greatly improving the disassembly and assembly efficiency of the metal filter ring and facilitating the replacement or cleaning of the filter.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0029] refer to Figure 1-2 A highly wear-resistant manganese phosphating nozzle comprises a nozzle body 1, a telescopic tube 2, a nozzle head 4 and a metal filter ring 12;

[0030] A telescopic tube 2 is telescopically installed on the upper part of the nozzle body 1, and a mounting cap 3 is integrally formed at the bottom of the nozzle head 4. The mounting cap 3 is detachably mounted on the top of the telescopic tube 2. A spring 10 is sleeved on the outside of the telescopic tube 2, and the spring 10 is arranged between the mounting cap 3 and the nozzle body 1. A quick connector 8 is integrally formed at the bottom of the nozzle body 1, and the nozzle head 4, the mounting cap 3, the telescopic tube 2 and the quick connector 8 are interconnected;

[0031] Among them, the bottom of the mounting cap 3 is integrally formed with a threaded connector 5, and the top of the telescopic tube 2 is provided with a threaded interface 11. The outer diameter of the threaded connector 5 corresponds to the inner diameter of the threaded interface 11, and the outer thread of the threaded connector 5 and the inner thread of the threaded interface 11 are meshed with each other. This threaded connection method makes installation and removal quick and easy, and facilitates the replacement of the nozzle head 4.

[0032] Secondly, the nozzle head 4 is processed by manganese phosphating. After the manganese phosphating treatment, a phosphate protective film is formed on the surface of the nozzle head 4, which makes the nozzle head have excellent wear resistance and can maintain good working condition during long-term use;

[0033] In addition, a chuck 9 is integrally formed on the outer wall of the nozzle body 1, and the diameter of the chuck 9 is larger than the nozzle body 1. The design of the chuck 9 allows the robot arm to realize the clamping operation of the nozzle, facilitating the automatic disassembly and assembly of the nozzle;

[0034] It should be noted that a sealing ring 13 is fixedly installed on the top of the telescopic tube 2 to improve the sealing performance. The outer diameter and inner diameter of the sealing ring 13 are respectively consistent with the outer diameter of the telescopic tube 2 and the inner diameter of the threaded interface 11. The sealing ring 13 effectively prevents air leakage at the connection between the telescopic tube 2 and the mounting cap 3, which affects the suction force.

[0035] In this embodiment, the mounting cap 3 can be quickly disassembled and assembled by threading the threaded joint 5 in the threaded interface 11. After the mounting cap 3 is disassembled, the spring 10 can be pulled out from the telescopic tube 2, so that the nozzle head 4 or the spring 10 can be quickly replaced when damaged, without discarding the entire nozzle, saving costs, and the replacement operation is simple and convenient.

[0036] refer to Figure 1, a support cylinder 6 is fixedly installed at the bottom of the threaded joint 5, a magnetic ring 7 is fixedly installed at the bottom of the support cylinder 6, an annular groove 14 is opened at the bottom inner side of the threaded interface 11, and a metal filter ring 12 is placed in the annular groove 14;

[0037] Among them, the inner and outer diameters of the support tube 6, the magnetic ring 7, the annular groove 14 and the metal filter ring 12 are consistent with each other. The metal filter ring 12 can be attracted by the magnetic ring 7. When the mounting cap 3 is disassembled, the support tube 6 and the bottom magnetic ring 7 can be removed. At this time, the magnetic ring 7 can drive the attracted metal filter ring 12 to be located in the annular groove 14 and taken out, which greatly improves the disassembly and assembly of the metal filter ring 12.

[0038] Secondly, a filter screen 15 is fixedly installed inside the metal filter ring 12, and the mesh number of the filter screen 15 is 200-500 mesh. The filter screen 15 can effectively filter fine dust particles;

[0039] In this embodiment, when the mounting cap 3 is disassembled, the metal filter ring 12 can be taken out together with the magnetic ring 7 , and the metal filter ring 12 can be easily disassembled and assembled, making it convenient to replace or clean the filter screen 15 .

[0040] Working principle: In the working process of the SMT machine, the highly wear-resistant manganese phosphating nozzle plays a vital role. After the SMT machine is started, suction is generated by the internal air system, and the suction is transmitted to the inside of the nozzle through the quick connector 8 at the bottom of the nozzle body 1, and finally the component is adsorbed by the nozzle head 4 for SMT operation. The nozzle head 4 has been treated with manganese phosphating, and the phosphate protective film on the surface gives it excellent wear resistance. It can maintain a good condition during frequent SMT operations and ensure long-term stable operation. During the SMT process, the spring 10 on the outside of the telescopic tube 2 acts as a buffer. When the nozzle contacts the electronic components for the suction operation, it can reduce the impact force and protect the electronic components from damage. When it is necessary to suck electronic components of different sizes, the telescopic tube 2 can be telescoped and adjusted inside the nozzle body 1 to adapt to different work requirements. The sealing ring 13 ensures the connection between the telescopic tube 2 and the mounting cap 3 The sealing of the metal filter ring 12 is prevented from leaking and affecting the suction force, ensuring that the electronic components can be stably sucked. During the suction process, the filter screen 15 inside the metal filter ring 12 can effectively filter out fine dust particles and other impurities in the air, preventing impurities from entering the suction nozzle and affecting the quality of electronic components. When the metal filter ring 12 needs to be replaced or the filter screen 15 needs to be cleaned, the mounting cap 3 is removed, and the support tube 6 and the magnetic ring 7 at the bottom of the mounting cap 3 will be removed together with the mounting cap 3. Since the magnetic ring 7 has an adsorption effect on the metal filter ring 12, the magnetic ring 7 will drive the adsorbed metal filter ring 12 to be taken out from the annular groove 14, which greatly improves the disassembly and assembly efficiency of the metal filter ring 12 and facilitates replacement or cleaning. After the mounting cap 3 is removed, a new suction nozzle head 4 or spring 10 can be replaced for use, without the need to discard the entire suction nozzle, reducing costs and protecting the environment.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
