Description

Technical Field

[0001] This utility model relates to the field of dispensing valve technology, specifically to a dispensing valve structure with spacing adjustment function. Background Technology

[0002] In precision manufacturing fields such as electronics manufacturing, semiconductor packaging, and medical devices, dispensing technology, as a key microfabrication process, is widely used in chip packaging, component bonding, sealing and protection, underfilling, thermal conductive material coating, and optical component assembly. The core of dispensing technology lies in precisely distributing specific amounts of adhesives, sealants, or other functional fluids to target locations to meet the performance requirements of products in areas such as electrical connection, mechanical fixation, environmental protection, and thermal management. High-precision dispensing valves ensure that the size, shape, and position of the adhesive dots meet micron-level or even nanometer-level precision requirements, thereby improving product reliability and yield.

[0003] Traditional dispensing valves typically employ a fixed needle structure, with a fixed distance between the needle and the workpiece. This makes it difficult to adapt to the dispensing needs of workpieces with different heights and shapes. When there are height differences on the workpiece surface, a fixed needle can lead to uneven dispensing, or even problems such as leaks or excessively large glue dots. For workpieces with complex shapes such as curved surfaces or steps, a fixed needle cannot guarantee that the glue dot is always located at the target position.

[0004] According to the authorization announcement number CN 216655190 U, a dispensing valve structure is disclosed, including a valve body, at least two injection cylinders, a first one-way valve, a second one-way valve, and a mixing tube. The injection cylinders are detachably connected to the valve body. The valve body has an inlet channel and an outlet channel that match the number of injection cylinders. One end of the inlet channel is connected to the adhesive via the first one-way valve and can be opened or closed, while the other end is connected to the injection cylinder. One end of the outlet channel is connected to the injection cylinder via the second one-way valve and can be opened or closed, while the other end is connected to the mixing tube.

[0005] The existing dispensing valve structure does not have an adjustment function during use and cannot dynamically adjust the spacing according to process requirements, which leads to a reduction in production efficiency. Therefore, there is a need for a dispensing valve structure with spacing adjustment function. Utility Model Content

The dispensing valve is moved by the set adjustment component, eliminating the need for manual adjustment of the dispensing valve, thereby solving the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dispensing valve structure with spacing adjustment function includes a body, an adjustable support frame is installed on the upper part of the body, and a rotation adjustment structure is installed in the middle of the adjustable support frame;

[0009] The rotation adjustment structure includes a connecting plate, an adjustment component is mounted on the outside of the connecting plate, a fixing block is mounted on the side of the adjustment component, two sets of pads are symmetrically mounted on the front side of the connecting plate and the side of the fixing block, cylinder fixing plates are mounted on the sides of the two sets of pads and the sides of the fixing block, several sets of slide cylinders are mounted on the side of each set of cylinder fixing plates, a glue spray valve fixing plate is mounted on the output end of each set of slide cylinders, and a glue spray valve is mounted on the side of each set of glue spray valve fixing plates.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides: a dispensing valve structure with spacing adjustment function, such as... Figures 1-5As shown, the machine includes a body 1, an adjustable support frame 2 is installed on the upper part of the body 1, and a rotating adjustment structure 3 is installed in the middle of the adjustable support frame 2. The adjustable support frame 2 can adjust the height and angle, so that the position and posture of the rotating adjustment structure 3 can be changed according to different work requirements.

[0026] The rotation adjustment structure 3 includes a connecting plate 4, an adjustment component 5 mounted on the outside of the connecting plate 4, a fixing block 6 mounted on the side of the adjustment component 5, two sets of pads 7 symmetrically mounted on the front side of the connecting plate 4, located on the side of the fixing block 6, cylinder fixing plates 8 mounted on the sides of the two sets of pads 7 and the sides of the fixing block 6, several sets of sliding cylinders 9 mounted on the side of each set of cylinder fixing plates 8, a glue spray valve fixing plate 10 mounted on the output end of each set of sliding cylinders 9, and a glue spray valve 11 mounted on the side of each set of glue spray valve fixing plates 10. The layout of the connecting plate 4, with the adjustment component 5 mounted on the outside, the fixing block 6 on the side, and the symmetrically mounted pads 7, allows the overall structure to support each other in space, enhancing structural stability and ensuring the reliability of the equipment during operation. The presence of the adjustment component 5 allows the structure to be flexibly adjusted according to actual working needs, adapting to different working scenarios and process requirements, improving the versatility and applicability of the equipment. The cylinder fixing plate 8, sliding cylinder 9, glue spray valve fixing plate 10, and glue spray valve 11 are also included. All components are installed independently. This modular design facilitates installation and disassembly, and allows for quick location and replacement of the corresponding components when equipment malfunctions or parts need to be replaced, reducing maintenance costs and time.

[0027] Preferably, two sets of guide rails 12 are symmetrically installed on the front side of the connecting plate 4. A slider 13 is slidably installed on the side of each set of guide rails 12. The fixing block 6 is installed on the side of the two sets of sliders 13. The combination of guide rails 12 and sliders 13 can provide precise guidance for the fixing block 6, ensuring that the fixing block 6 moves along a predetermined trajectory during sliding, avoiding deviation or shaking. This ensures the movement accuracy of components such as the dispensing valve installed on the fixing block 6, which is beneficial to improving the accuracy and consistency of operations such as spraying and dispensing glue.

[0028] Furthermore, the adjustment component 5 includes a motor mounting plate 501 installed on the rear side of the connecting plate 4. A stepper motor 502 is mounted on one side of the motor mounting plate 501. The output end of the stepper motor 502 passes through the middle of the motor mounting plate 501 and is connected to a drive wheel 503. The stepper motor 502 has good stability and is not prone to step loss during operation. The stepper motor 502 can accurately control the rotation angle and speed of the drive wheel 503. This provides high-precision power output for the position adjustment control of the dispensing valve 11, ensuring the accuracy and consistency of the process.

[0029] Furthermore, two sets of bearing mounting seats 504 are symmetrically installed on the front side of the connecting plate 4. Each set of bearing mounting seats 504 contains a bearing 505. A lead screw 506 is installed in the middle of the two sets of bearings 505. The lead screw 506 cooperates with the bearings 505 to convert rotary motion into high-precision linear motion. During equipment operation, linear motion ensures that the components mounted on the lead screw 506 move along a precise trajectory.

[0030] It is worth noting that a connecting plate is slidably mounted in the middle of the lead screw 506, and the fixing block 6 is fixedly mounted on the side of the connecting plate. A driven wheel 507 is mounted on one end of the lead screw 506. The drive wheel 503 and the driven wheel 507 are mounted on the same synchronous belt 508. The synchronous belt drive 508 is a meshing drive. The drive wheel 503 and the driven wheel 507 are connected by the synchronous belt 508. There will be no slippage during the transmission process. It can ensure that the speed of the lead screw 506 and the output speed of the stepper motor 502 maintain a stable transmission ratio, so that the movement of the connecting plate and the fixing block 6 is more stable, which is conducive to improving the stability and consistency of the entire adjustment assembly 5.

[0031] Specifically, two sets of sensor pads 14 are symmetrically installed on the top of the connecting plate 4. A sensor 15 is installed on the upper part of each set of sensor pads 14. A valve origin sensing plate 16 is installed on the upper part of the fixed block 6 corresponding to the sensor 15. A vernier scale 17 is installed on the front side of the connecting plate 4 corresponding to the valve origin sensing plate 16. The sensor 15 and the valve origin sensing plate 16 work together to accurately determine the fixed block 6 and the valve origin sensing plate 16 installed on it. The sensor 15 can monitor the position change of the fixed block 6 in real time. When the fixed block 6 passes the sensor 15 during movement, the sensor 15 will send a signal to the control system of the equipment. The vernier scale 17 provides an intuitive position reference for the operator. The operator can quickly and roughly determine the position of the fixed block 6 by observing the scale on the vernier scale 17.

[0032] More specifically, a side plate 18 is installed on the rear side of the connecting plate 4, located on one side of the stepper motor 502. A camera 19 is slidably installed on the side of the side plate 18, and a light source 20 is slidably installed on the side of the side plate 18 below the camera 19. Both the camera 19 and the light source 20 are slidably installed, and their positions and angles can be easily adjusted on the side plate 18 according to actual detection or shooting needs. The camera 19 can identify and locate the position and posture of the workpiece, providing position information for subsequent precise operations. The installation of the light source 20 can provide stable and uniform illumination for the shooting of the camera 19.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
