[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example

[0021] like Figure 1-Figure 3 As shown, the utility model provides a vacuum suction cup.

[0022] It includes a suction cup body 1 and a bracket, wherein the bracket is arranged at the upper end of the suction cup body 1, and the bracket includes a first bracket 2 and a second bracket 3, wherein the first bracket 2 and the second bracket 3 are arranged at intervals, and the first bracket 2 and the second bracket 3 are symmetrically arranged along the horizontal axis of the suction cup body 1, and the first bracket 2 and the second bracket 3 are both provided with positioning holes 4, wherein the positioning holes 4 are at least arranged in two groups, and the two groups of positioning holes 4 are respectively arranged at both ends of the bracket, and the first bracket 2 and the second bracket 3 are both provided with positioning grooves 5, and the suction cup body 1 is positioned and fixed on the workbench through the positioning holes 4 and the positioning grooves 5;

[0023] The positioning hole 4 is a threaded hole, which is fixedly connected to the workbench through a threaded connector to achieve stable fixation of the suction cup body 1 on the workbench.

[0024] Reinforcing ribs are provided on the first bracket 2 and the second bracket 3 to enhance the overall structural strength and stability of the first bracket 2 and the second bracket 3 .

[0025] It also includes a vacuum generator, which is connected to the suction cup body 1 and is used to generate negative pressure to enable the suction cup body 1 to adsorb the object, wherein the vacuum generator is connected to the inside of the suction cup body 1 through a pipeline, and a control valve is provided on the pipeline to control the generation and disconnection of negative pressure.

[0026] The first bracket 2 and the second bracket 3 are both fixedly welded to the suction cup body 1 .

[0027] It also includes a sensor system, which includes a plurality of pressure sensors 6 for real-time monitoring of the adsorption pressure of the suction cup body 1 and adjusting the negative pressure output of the vacuum generator through a feedback mechanism to ensure stable and efficient adsorption performance.

[0028] A plurality of pressure sensors 6 are arranged at key positions of the suction cup body 1, such as the center or edge of the adsorption surface. The plurality of pressure sensors 6 are arranged so as to directly sense the pressure changes generated during the adsorption process.

[0029] The pressure sensor 6 continuously measures the pressure of the adsorption surface and converts the pressure data into electrical signals.

[0030] These electrical signals are then collected by a data acquisition system, which can be a microcontroller, PLC (programmable logic controller), or other type of controller.

[0031] The controller processes and analyzes the collected pressure data and calculates key parameters such as the current average pressure, maximum pressure, and minimum pressure.

[0032] By comparing these parameters with the preset safety range or target value, the controller can determine whether the current adsorption state is stable and efficient.

[0033] If the controller detects that the adsorption pressure is lower than the preset minimum value, it means that the adsorption force is insufficient. At this time, the controller will send a signal to the vacuum generator, requiring it to increase the negative pressure output to enhance the adsorption force.

[0034] On the contrary, if the adsorption pressure is higher than the preset maximum value, it means that the adsorption force is too strong, which may cause damage to the object or damage to the suction cup body 1. At this time, the controller will send a signal to reduce the negative pressure output of the vacuum generator.

[0035] Automatic adjustment and optimization:

[0036] Through continuous real-time monitoring and adjustment, the sensor system ensures that the suction cup maintains optimal adsorption under various working conditions.

[0037] This automatic adjustment function not only improves the stability and reliability of the suction operation, but also extends the service life of the suction cup and vacuum generator.

[0038] Fault warning and safety protection:

[0039] In addition to the real-time adjustment function, the sensor system can also set an early warning mechanism. When an abnormal situation is detected (such as a sudden drop or rise in pressure), the system will sound an alarm and take corresponding protective measures, such as automatically shutting down the vacuum generator or activating the emergency release mechanism to prevent possible safety accidents.

[0040] In summary, by integrating a sensor system of multiple pressure sensors 6, the vacuum suction cup can realize real-time monitoring and automatic adjustment of the adsorption pressure. This intelligent design not only improves the performance and safety of the equipment, but also provides users with a more convenient and efficient operation experience.

[0041] The use process of the utility model includes the following steps:

[0042] Installation and positioning:

[0043] Place the vacuum suction cup on the workbench, and ensure that the suction cup body 1 is stably fixed and accurately positioned on the workbench through the positioning holes 4 and positioning grooves 5 on the bracket. Use threaded connectors to fix it to the workbench to further enhance the stability of the suction cup.

[0044] Prepare for adsorption:

[0045] Connect the pipeline between the vacuum generator and the suction cup body 1, and ensure that the control valve on the pipeline is in the closed state, turn on the vacuum generator, and prepare to generate negative pressure.

[0046] Adsorption operation:

[0047] Place the object to be adsorbed on the suction cup body 1, open the control valve on the pipeline, and the vacuum generator starts to generate negative pressure, which is transmitted to the suction cup body 1 through the pipeline, thereby achieving the suction cup adsorption of the object.

[0048] Adsorption monitoring and adjustment:

[0049] The multiple pressure sensors 6 in the sensor system monitor the adsorption pressure of the suction cup body 1 in real time. If the sensor detects that the adsorption pressure is abnormal, the negative pressure output of the vacuum generator is automatically adjusted through a feedback mechanism to ensure stable and efficient adsorption performance.

[0050] Release the object:

[0051] When the adsorbed object needs to be released, the vacuum generator is turned off or the control valve on the pipeline is opened to eliminate the negative pressure inside the suction cup body 1. The object falls off naturally due to the loss of negative pressure adsorption force, thus completing the entire adsorption and release operation process.

[0052] Through the above working steps, the vacuum suction cup can achieve stable and precise adsorption operation, and ensure the efficiency and safety of the adsorption process through real-time monitoring and feedback adjustment of the sensor system. This design not only improves production efficiency, but also reduces risks during operation.

[0053] The present application mainly includes a suction cup body 1, a bracket, a vacuum generator and a related sensor system, wherein the bracket is designed to stably support the suction cup body 1, and realize precise positioning on the workbench through the positioning hole 4 and the positioning groove 5. The vacuum generator is connected to the inside of the suction cup body 1 through a pipeline to generate negative pressure, thereby realizing the adsorption of the object by the suction cup body 1. The sensor system monitors the adsorption pressure of the suction cup body 1 in real time, and adjusts the negative pressure output of the vacuum generator through a feedback mechanism to ensure stable and efficient adsorption performance.

[0054] The present application significantly improves the stability of the suction cup by optimizing the design of the bracket structure, including the interval setting of the first bracket 2 and the second bracket 3 and the symmetrical design along the horizontal axis of the suction cup body 1. The positioning holes 4 and positioning grooves 5 on the bracket are combined with the workbench to ensure the precise positioning of the suction cup on the workbench, thereby improving the accuracy of the adsorption operation.

[0055] The introduction of the sensor system of the present application, especially the use of multiple pressure sensors 6, makes the adsorption process more intelligent. The sensor can monitor the adsorption pressure of the suction cup body 1 in real time, and automatically adjust the negative pressure output of the vacuum generator through a feedback mechanism. This intelligent adsorption control not only ensures the stability and efficiency of the adsorption, but also effectively avoids operational errors or equipment damage caused by excessive or insufficient adsorption force.

[0056] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
