[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the following is a further detailed description of the multi-dimensional pressure monitoring device for the dispensing head of the utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0019] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "center", "longitudinal", "lateral", "up", "down", "left", "right", "inside", "outside", "front end", "rear end", "head", "tail", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0021] See also Figure 1 to Figure 2 The multi-dimensional pressure monitoring system of the dispensing head 21 of the embodiment of the utility model includes a multi-dimensional force sensor 1; and a dispensing device 2, wherein the dispensing device 2 includes a dispensing head 21, a connecting component 22 and a connecting plate 23, wherein the connecting component 22 is arranged on one side of the connecting plate 23, and the two ends of the dispensing head 21 are connected to the connecting component 22, and the other side of the connecting plate 23 is fitted and connected to the multi-dimensional force sensor 1.

[0022] In the above embodiment, the dispensing head 21 is fixed on the connecting plate 23 through the connecting assembly 22. The connecting plate 23 is fixed to the driving device after being threadedly connected to the multi-dimensional force sensor 1. The connecting plate 23 and the driving device are locked by threaded connection to ensure the stability and accuracy of the entire system. During the dispensing process, a certain distance is maintained between the dispensing head 21 and the platform. When the glue is applied, the distance between the dispensing head 21 and the platform will change. If the Z-direction displacement is too large, causing the dispensing head 21 to contact the product on the platform, or contact with other mechanisms when moving in the XY direction, then a small displacement will be generated at the connection between the dispensing head 21 and the sensor. The multi-dimensional force sensor 1 can sensitively capture these small displacements and output the size of the displacement to the sensor driver in the form of current. After a series of processing, the size of the force is finally output. The control module can receive and process these data and adjust the pressure or position of the dispensing head 21 according to actual needs.

[0023] In addition, if the measured value of the multi-dimensional force sensor 1 exceeds a preset threshold, an alarm is issued to remind the user to check the pressure or position of the dispensing head 21 to ensure the stability and safety of the production process.

[0024] Please refer to Figure 1 to Figure 2 In another embodiment, the connecting component 22 includes a first connecting member 221 and a second connecting member 222 , wherein the first connecting member 221 is disposed on an end surface of the connecting plate 23 , and the second connecting member 222 is disposed on the other end surface of the connecting plate 23 .

[0025] In the above embodiment, the first connecting member 221 is arranged on the end face of the connecting plate 23. Such a design can ensure that the connection between the dispensing head 21 and the first connecting member 221 is tighter and more stable. At the same time, the second connecting member 222 is arranged on the other end face of the connecting plate 23, which further enhances the stability of the entire system. The connecting component 22 transmits the force signal of the dispensing head 21 to the multi-dimensional force sensor 1. When the dispensing head 21 is subjected to external forces, these forces will be transmitted to the connecting component 22, and then captured by the multi-dimensional force sensor 1 and converted into electrical signals for subsequent processing and display. Through the design of the double connecting member, the position and direction of the dispensing head 21 can be controlled more accurately. At the same time, since the first connecting member 221 and the second connecting member 222 are respectively located on the end faces of the connecting plate 23, this makes the installation and maintenance of the entire system easier. This design also helps to improve the reliability and durability of the system.

[0026] Please refer to Figure 1 to Figure 2 In another embodiment, a through hole 231 is provided at a portion where the connecting plate 23 and the multi-dimensional force sensor 1 are in contact.

[0027] In the above embodiment, firstly, the amount of material used in the connecting plate 23 can be reduced, thereby reducing the overall weight. This helps to improve the mobility and response speed of the system. Secondly, the local stiffness of the connecting plate 23 can be enhanced, so that it is not easy to deform when subjected to external forces, ensuring the accuracy of the measurement results. Finally, the through hole 231 allows heat to dissipate quickly on the surface of the connecting plate 23, which is particularly important for high-power or multi-component systems, and can prevent performance degradation or failure caused by overheating. In some application scenarios, the through hole 231 can be used to balance airflow or air pressure to ensure that the measurement is not affected by external airflow or pressure fluctuations.

[0028] Please refer to Figure 1 to Figure 2 In another embodiment, it further includes a mounting plate 3, the cross section of the mounting plate 3 is a convex shape, and the mounting plate is connected to the multi-dimensional force sensor 1.

[0029] In the above embodiment, the mounting plate 3 provides a stable base for the multi-dimensional force sensor 1, ensuring that the sensor will not move or vibrate during the measurement process. By connecting with the mounting plate, the mounting plate 3 can firmly fix the multi-dimensional force sensor 1 in the desired position, ensuring that the sensor will not shift when subjected to external forces. The convex-shaped design increases the rigidity and stability of the mounting plate 3, making it less likely to bend or deform when subjected to external forces. This helps to improve the measurement accuracy of the multi-dimensional force sensor 1. At the same time, the convex-shaped cross-section can also minimize the space occupied by the mounting plate 3 while ensuring rigidity, making the entire system more compact.

[0030] Please refer to Figure 1 to Figure 2In another embodiment, it further includes a driving device connected to the mounting plate 3 for driving the mounting plate 3.

[0031] In the above embodiment, the driving device can drive the mounting plate 3 to move on a predetermined track by being connected to the mounting plate 3. This allows the dispensing head 21 to adjust the position and movement path as needed.

[0032] Please refer to Figure 1 to Figure 2 In another embodiment, a control module is further included for receiving a signal from the multi-dimensional force sensor 1 and adjusting the pressure of the dispensing head 21 according to the signal.

[0033] In the above embodiment, the control module continuously receives signals from the multi-dimensional force sensor 1, which reflect the force exerted on the dispensing head 21. The control module processes the received signals in real time, extracts important information about the pressure, and performs further analysis according to a preset algorithm. Based on the processed data, the control module can calculate the pressure required by the dispensing head 21 and adjust the output of the drive device accordingly, thereby changing the pressure of the dispensing head 21. The multi-dimensional force sensor serves as an alarm function to prevent the needle from scratching the product during batch production, resulting in batch defects, and to precisely adjust it to ensure that the pressure remains stable during the entire dispensing process.

[0034] Please refer to Figure 1 to Figure 2 In another embodiment, the control module is connected to the driving device and adjusts the output of the driving device according to the received signal of the multi-dimensional force sensor 1.

[0035] In the above embodiment, the control module can transmit the received signals of the multi-dimensional force sensor 1 to the drive device by connecting with the drive device. These signals contain key information about the force applied to the dispensing head 21.

[0036] Please refer to Figure 1 to Figure 2 In another embodiment, it also includes a display connected to the control module for displaying the received signal of the multi-dimensional force sensor 1.

[0037] In the above embodiment, the display can receive and display the signal emitted by the multi-dimensional force sensor 1 in real time, so that the user can intuitively observe the pressure state and changes of the dispensing head 21. At the same time, it also has a visual interface. Through a friendly user interface, the display can display the received signal in the form of graphics, charts or numbers, making it easier for users to understand and analyze data.

[0038] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
