Description

Technical Field

[0001] This utility model relates to the field of dispensing valve striker technology, specifically to a diamond striker for a piezoelectric dispensing valve used in 3C product packaging. Background Technology

[0002] Currently, most dispensing pins on the market are made of tungsten carbide or stainless steel, which can meet the dispensing needs of ordinary adhesives. However, some special adhesives are highly corrosive to tungsten carbide or stainless steel, causing them to wear down easily during use. This necessitates replacing the pin after a short period of use, significantly reducing dispensing efficiency and quality. Therefore, we propose a diamond pin for a piezoelectric dispensing valve encapsulated in 3C products. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a diamond striker for a piezoelectric dispensing valve used in 3C product packaging.

[0004] The technical solution adopted by this utility model to solve its technical problem is a diamond striker for a piezoelectric dispensing valve for 3C product packaging, including a needle seat. A threaded post is integrally constructed on the outer end surface of the needle seat, and a diamond needle body is screwed onto the outer periphery of the threaded post. A threaded hole is opened at the end of the diamond needle body away from the needle seat, and a stud for support is screwed into the threaded hole. A diamond needle tip is integrally constructed at the end of the stud located outside the threaded hole.

[0005] The stud has a straight hole, and a steel ball that fits into the inner wall of the stud is slidably installed in the straight hole. There are two sets of steel balls, and a spring for pushing the steel ball to move is assembled between the two sets of steel balls.

[0006] By adopting the above technical solution, in the process of using the piezoelectric dispensing valve ejector pin for 3C product packaging, the pin seat, diamond pin body and diamond pin head are connected to each other by threaded post, stud and threaded hole, in a three-section design. When a section is damaged, it can be replaced separately without replacing the entire ejector pin. At the same time, the diamond material ejector pin has good corrosion resistance, which effectively improves the service life of the ejector pin.

[0007] When the diamond needle tip is screwed into the threaded hole on the diamond needle body via a stud, the spring in the straight hole on the inner circumference of the stud can push the steel ball, so that one end of the steel ball can extend out of the straight hole and fit into the groove preset on the inner side of the threaded hole. This improves the stability of the screwed connection between the stud and the threaded hole, and also improves the stability of the connection between the diamond needle tip and the diamond needle body, so that the diamond needle tip and the diamond needle body can be used stably.

[0008] Specifically, the outer end surface of the diamond needle body is integrally constructed with a ring that fits the diamond needle tip.

[0009] By adopting the above technical solution, the outer ring of the diamond needle body can fit into the groove on the diamond needle head, which facilitates the tightness of the connection between the diamond needle head and the diamond needle body, thereby reducing the situation of glue seeping into the two.

[0010] Specifically, the inner side of the screw hole has an integrally constructed hemisphere that fits with the stud.

[0011] By adopting the above technical solution, the hemisphere in the screw hole and the stud can fit together, which facilitates the improvement of the stability of the screw connection between the stud and the screw hole.

[0012] Specifically, the end of the threaded post away from the needle seat is integrally constructed with a straight rod that is inserted and connected to the diamond needle body.

[0013] By adopting the above technical solution, the straight rod on the outside of the threaded column can be interlocked with the diamond needle body, thereby improving the stability of the connection between the diamond needle body and the needle seat, and enabling the diamond needle body to operate more stably.

[0014] Specifically, the outer peripheral surface of the diamond needle is provided with grooves, and there are multiple sets of grooves.

[0015] By adopting the above technical solution, the multiple sets of grooves on the outer periphery of the diamond needle make it easier to disassemble and assemble the diamond needle body, needle seat and diamond needle tip, and facilitate replacement when wear is severe.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of threaded post, diamond needle body, threaded hole, threaded post and diamond needle tip, in the process of using the impact pin of the piezoelectric dispensing valve for 3C product packaging, the needle seat, diamond needle body and diamond needle tip are connected to each other by threaded post, threaded post and threaded hole, in a three-section design. When a section is damaged, it can be replaced individually without replacing the entire impact pin. At the same time, the impact pin made of diamond material has good corrosion resistance, effectively improving the service life of the impact pin, and can be used for the packaging and filling of PCB boards, chips and semiconductors. It also has the characteristics of high wear resistance, corrosion resistance and stable glue application.

[0018] 2. The technical solution of this application, through the design of a straight hole, a steel ball, and a spring, allows the spring in the straight hole on the inner circumference of the stud to push the steel ball when the diamond needle tip is connected to the screw hole on the diamond needle body via a stud. This allows one end of the steel ball to extend out of the straight hole and engage with the groove pre-set on the inner side of the screw hole, thereby improving the stability of the connection between the stud and the screw hole, and also improving the stability of the connection between the diamond needle tip and the diamond needle body. This ensures that the diamond needle tip and the diamond needle body can be used stably. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a diamond striker for a piezoelectric dispensing valve for 3C product packaging, including a needle seat 1, a threaded post 2 integrally formed on the outer end surface of the needle seat 1, and a diamond needle body 3 screwed onto the outer periphery of the threaded post 2, a threaded hole 4 is opened at the end of the diamond needle body 3 away from the needle seat 1, and a stud 5 for support is screwed into the threaded hole 4, and a diamond needle tip 6 is integrally formed at the end of the stud 5 located outside the threaded hole 4; a straight hole 8 is opened in the stud 5, and a steel ball 9 that fits into the inner wall of the threaded hole 4 is slidably installed in the straight hole 8, and there are two sets of steel balls 9, and a spring 10 for pushing the steel ball 9 to move is assembled between the two sets of steel balls 9.

[0026] When used in the process of using the piezoelectric dispensing valve ejector pin for 3C product packaging, the pin seat 1, diamond pin body 3 and diamond pin head 6 are connected to each other by threaded post 2, stud 5 and threaded hole 4, forming a three-section design. If a section is damaged, it can be replaced separately without replacing the entire ejector pin. At the same time, the diamond material ejector pin has good corrosion resistance, which effectively improves the service life of the ejector pin.

[0027] When the diamond needle 6 is screwed into the screw hole 4 on the diamond needle body 3 via the stud 5, the spring 10 in the straight hole 8 on the inner circumference of the stud 5 can push the steel ball 9, so that one end of the steel ball 9 can extend out of the straight hole 8 and fit into the groove preset on the inner side of the screw hole 4. This improves the stability of the screw connection between the stud 5 and the screw hole 4, and also improves the stability of the connection between the diamond needle 6 and the diamond needle body 3, so that the diamond needle 6 and the diamond needle body 3 can be used stably.

[0028] like Figure 2 and Figure 3 As shown, the outer end surface of the diamond needle body 3 is integrally constructed with a ring body 7 that fits with the diamond needle tip 6.

[0029] When in use, the outer ring 7 of the diamond needle body 3 can fit into the groove on the diamond needle tip 6, which facilitates the tightness of the connection between the diamond needle tip 6 and the diamond needle body 3, thereby reducing the situation of glue seeping into the two.

[0030] like Figure 2 and Figure 3 As shown, the inner side of the screw hole 4 has an integrally constructed hemispherical body 11 that fits with the stud 5.

[0031] When in use, the hemisphere 11 in the screw hole 4 and the stud 5 can fit together, which helps to improve the stability of the screw connection between the stud 5 and the screw hole 4.

[0032] like Figure 2 As shown, the end of the threaded column 2 away from the needle seat 1 has an integrally constructed straight rod 12 that is inserted and connected to the diamond needle body 3.

[0033] When in use, the straight rod 12 on the outside of the threaded column 2 can be inserted into the diamond needle body 3, thereby improving the stability of the connection between the diamond needle body 3 and the needle seat 1, so that the diamond needle body 3 can operate more stably.

[0034] like Figure 1 As shown, the outer peripheral surface of the diamond needle body 3 is provided with grooves 13, and there are multiple sets of grooves 13.

[0035] During use, the multiple sets of grooves 13 on the outer periphery of the diamond needle body 3 make it easier to disassemble and assemble the diamond needle body 3, the needle seat 1, and the diamond needle head 6, and facilitate replacement when wear is severe.

[0036] The working principle and usage process of this utility model are as follows: In use, first install the corresponding structural components in the appropriate positions. During the use of the piezoelectric dispensing valve ejector pin for 3C product packaging, the pin seat 1, diamond pin body 3, and diamond pin head 6 are connected to each other via threaded post 2, stud 5, and threaded hole 4, forming a three-section design. If any section is damaged, it can be replaced individually without replacing the entire ejector pin. Simultaneously, the diamond material of the ejector pin has excellent corrosion resistance, effectively improving its service life. When the head 6 is screwed into the screw hole 4 on the diamond needle body 3 via the stud 5, the spring 10 in the straight hole 8 on the inner circumference of the stud 5 can push the steel ball 9, so that one end of the steel ball 9 can extend out of the straight hole 8 and fit into the groove preset on the inner side of the screw hole 4. This improves the stability of the screw connection between the stud 5 and the screw hole 4, and also improves the stability of the connection between the diamond needle head 6 and the diamond needle body 3. This allows the diamond needle head 6 and the diamond needle body 3 to be used stably, and makes the dispensing valve striker more stable during dispensing.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
