Description

Technical Field

[0001] This utility model relates to the field of piezoelectric injection valve technology, and in particular to a quick-release piezoelectric injection valve. Background Technology

[0002] In industries such as microelectronics packaging, semiconductor manufacturing, biomedicine, and precision dispensing, extremely high demands are placed on the precise, high-speed, and low-precision distribution of fluids. Piezoelectric jet valves, as fluid control devices based on the piezoelectric effect, have become one of the key technologies for meeting these requirements. The core principle of piezoelectric jet valves is to utilize the characteristic of piezoelectric materials to undergo rapid, micron-level deformation under the influence of an electric field, thereby driving the movement of the valve core assembly and achieving precise control of fluid jetting.

[0003] Currently, to achieve high-precision jetting, the nozzles and internal flow channels of piezoelectric jet valves are typically designed to be at the micrometer level. This intricate structure places extremely stringent requirements on the cleanliness and compatibility of the fluid. In practical applications, tiny particles or localized solidification in the fluid can easily cause blockages in narrow flow channels or nozzles. Once blockage occurs, the cleaning process is extremely cumbersome. Existing technologies usually require skilled operators to disassemble the core components one by one and treat them with specialized solvents and ultrasonic cleaning machines. However, the existing structure is cumbersome to disassemble and reassemble, and assembly errors are prone to occur during assembly. Repeated disassembly and reassembly lead to wear on precision components, affecting the normal operation of the piezoelectric jet valve. Utility Model Content

[0030] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1-3 As shown, this utility model provides a quick-release piezoelectric injection valve that can achieve precise control of fluid injection.

[0033] The quick-release piezoelectric jet valve includes a base 1, a locking assembly 2, a glue spraying assembly 3, and a glue supply assembly 4. The glue supply assembly 4 is connected to the glue spraying assembly 3 and can supply the fluid used for spraying to the glue spraying assembly 3.

[0034] The locking assembly 2 includes a support 21, a first pressing member 22, a second pressing member 23, a first locking member 24, and a second locking member 25. The support 21 is disposed on the base 1. One end of the first pressing member 22 and the second pressing member 23 are both hinged to the support 21, so that the first pressing member 22 and the second pressing member 23 can swing on the support 21. The other end of the first pressing member 22 and the second pressing member 23 are detachably connected to the support 21 through the first locking member 24 and the second locking member 25, respectively. So that when the first locking member 24 and the second locking member 25 are connected to the support 21, the first pressing member 22 and the second pressing member 23 can be locked to the side facing the surface of the support 21. After the first locking member 24 and the second locking member 25 are removed from the support 21, the first pressing member 22 and the second pressing member 23 can swing to the side away from the surface of the support 21 to open the support 21.

[0035] The adhesive spraying assembly 3 can be placed on the support base 21. The first pressing member 22 and the second pressing member 23 can press the opposite sides of the adhesive spraying assembly 3 onto the support base 21 along the extension direction, so that the adhesive spraying assembly 3 is fixedly installed on the support base 21. After the first pressing member and the second pressing member are opened, the adhesive spraying assembly 3 can be directly removed without disassembling it piece by piece. This structure is simple, easy to install and disassemble, and can facilitate the quick cleaning of the adhesive spraying assembly 3. At the same time, since the adhesive spraying assembly 3 is fixed on the support base 21 by the pressing of the first pressing member 22 and the second pressing member 23, it will not cause wear on the precision parts of the adhesive spraying assembly 3, and avoid wear caused by repeated disassembly and assembly, which would affect the normal use of the piezoelectric spray valve.

[0036] Meanwhile, the locking assembly 2 also includes an adjusting member 26. The bearing seat 21 has a waist hole 214. The adjusting member 26 passes through the waist hole 214 and is threaded to the base 1. Thus, by cooperating with the waist hole 214, the position of the bearing seat 21 on the base 1 can be adjusted. That is, after rotating the adjusting member 26 to loosen the bearing seat 21, the bearing seat 21 can move on the base 1. After rotating the adjusting member 26 to press the bearing seat 21, the bearing seat 21 can be fixed on the base 1. This structure can adjust the position of the bearing seat 21 to meet actual usage requirements. Optionally, the first locking member 24 and the second locking member 25 are both butterfly anti-loosening screws. The butterfly anti-loosening screws can not only facilitate the locking and fixing of the first pressing member 22 and the second pressing member 23, but also prevent them from falling off. Alternatively, the first pressing member 22 and the second pressing member 23 have grooves on the side facing the support seat 21. When the first pressing member 22 and the second pressing member 23 press the adhesive spraying assembly 3 onto the support seat 21, part of the adhesive spraying assembly 3 is located in the groove, thereby achieving the pressing and positioning of the adhesive spraying assembly 3.

[0037] like Figure 2 and Figure 3As shown, the glue spraying assembly 3 includes a valve body 31, a limiting and fixing member 32, a sealing connector 33, a valve nozzle 34, and a connecting joint 35. One end of the valve body 31 is sealed and inserted into the sealing connector 33, and the other end of the valve body 31 is inserted into the limiting and fixing member 32. The valve nozzle 34 is connected to the free end of the valve body 31 and threadedly connected to the inner wall of the limiting and fixing member 32. One end of the connecting joint 35 is connected to the sealing connector 33, and the other end of the connecting joint 35 is connected to the glue supply assembly 4. Thus, the fluid provided by the glue supply assembly 4 can be sprayed out after passing through the connecting joint 35, the sealing connector 33, the valve body 31, and the valve nozzle 34 in sequence. The first crimping member 22 and the second crimping member 23 are respectively used to crimp the limiting fixing member 32 and the sealing connection member 33 onto the bearing seat 21, so that the valve nozzle 34, valve body 31 and connecting joint 35 can be exposed from the first crimping member 22 and the second crimping member 23, so as to avoid the crimping affecting the use of the valve nozzle 34, valve body 31 and connecting joint 35. The valve nozzle 34 is threaded to the inner wall of the limiting fixing member 32, and one end of the valve body 31 is inserted into the limiting fixing member 32. Therefore, the valve nozzle 34 and the valve body 31 can be directly aligned and communicated, and the valve nozzle 34 can be removed from the limiting fixing member 32 for easy cleaning. Optionally, a sealing ring is provided on the end of the valve body 31 near the sealing connection member 33, and the valve body 31 is inserted into the sealing connection member 33 through the sealing ring.

[0038] Furthermore, the support seat 21 has a first limiting groove 211, a second limiting groove 212, and a third limiting groove 213 that are connected to each other in sequence. The limiting fixing member 32 is embedded in the first limiting groove 211, the valve body 31 is embedded in the second limiting groove 212, and the sealing connector 33 is embedded in the third limiting groove 213. Through the setting of the first limiting groove 211, the second limiting groove 212, and the third limiting groove 213, the limiting fixing member 32, the valve body 31, and the sealing connector 33 can be positioned sequentially on the support seat 21. The assembly accuracy is high, which facilitates the first pressing member 22 and the second pressing member 23 to press and fix the limiting fixing member 32 and the sealing connector 33 respectively.

[0039] like Figure 1 and Figure 2As shown, the glue supply assembly 4 includes a mounting bracket 41, a glue storage tank 42, a mounting sleeve 43, and a material storage tank 44. The mounting bracket 41 is mounted on the base 1 and spaced apart from the support seat 21. The glue storage tank 42 is mounted on the mounting bracket 41 and connected to the glue spraying assembly 3 via a pipeline. The material storage tank 44 is embedded in the mounting sleeve 43 and connected to the glue storage tank 42 via a pipeline. Thus, the material storage tank 44 can stably supply fluid to the glue storage tank 42, and the glue storage tank 42 can accurately supply fluid to the glue spraying assembly 3. The glue supply assembly 4 also includes a locking element 45. The mounting bracket 41 is rotatably mounted on the base 1, and the locking element 45 can pass through the mounting bracket 41 and be threaded to the base 1. Rotating the mounting bracket 41 allows adjustment of the position and angle of the glue storage tank 42, facilitating the miniaturized design of the quick-release piezoelectric spray valve.

[0040] The mounting bracket 41 is connected to at least two U-shaped clamps 411. The glue storage tank 42 is respectively engaged with the opposite sides of each of the at least two U-shaped clamps 411 along its extension direction. This allows for quick installation and removal of the glue storage tank 42 from the mounting bracket 41. Furthermore, the type of U-shaped clamp 411 can be changed to accommodate glue storage tanks 42 of different sizes. Optionally, the two free ends of the U-shaped clamp 411 are folded outwards into a V-shape to facilitate the quick insertion of the glue storage tank 42 into the U-shaped clamp 411.

[0041] Furthermore, the glue supply assembly 4 also includes a first L-shaped bend joint 461 and a second L-shaped bend joint 462. One end of the first L-shaped bend joint 461 is connected to the outlet of the glue storage tank 42, and the other end of the first L-shaped bend joint 461 is connected to the glue spraying assembly 3 through a pipeline. One end of the second L-shaped bend joint 462 is connected to the inlet of the glue storage tank 42, and the other end of the second L-shaped bend joint 462 is connected to the storage tank 44 through a pipeline. By setting the first L-shaped bend joint 461 and the second L-shaped bend joint 462, the length occupied along the extension direction of the glue storage tank 42 can be reduced, thereby facilitating the miniaturization design of the quick-release piezoelectric spray valve.

[0042] Furthermore, the adhesive supply assembly 4 also includes a first liquid level sensor 471 and a second liquid level sensor 472. The first liquid level sensor 471 is threadedly connected to the mounting bracket 41 and is used to monitor the liquid level height of the adhesive storage tank 42. The second liquid level sensor 472 is threadedly connected to the mounting sleeve 43 and is used to monitor the liquid level height of the storage tank 44. The use of the first liquid level sensor 471 and the second liquid level sensor can prevent the fluid from running out and also help to determine whether there is pipeline blockage or abnormal pressure. Both the first liquid level sensor 471 and the second liquid level sensor 472 can have their sensing distance adjusted by rotating their external threads to meet actual usage requirements. Optionally, the liquid level sensor includes a sensor probe and an amplifier. The amplifier is located at the rear end of the sensor probe. By placing the amplifier at the rear, the overall size of the liquid level sensor can be reduced.

[0043] Furthermore, the glue supply assembly 4 also includes a first quick-release self-locking connector 48 and a second quick-release self-locking connector 49. The first quick-release self-locking connector 48 is connected to the glue storage tank 42 via a pipeline, and the second quick-release self-locking connector 49 is connected to the material storage tank 44 via a pipeline. The first quick-release self-locking connector 48 is detachably connected to the second quick-release self-locking connector 49. The first quick-release self-locking connector 48 can be quickly separated from the second quick-release self-locking connector 49, and the channel is automatically locked when separated to ensure that the fluid does not leak, which facilitates the maintenance and use of the quick-release piezoelectric injection valve. The first quick-release self-locking connector 48 and the second quick-release self-locking connector 49 are connected and installed on the base 1.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
