[0023] Embodiment one

[0024] Please refer to Figures 1-4 As shown in the figure, the utility model provides a technical scheme: an adsorption force adjustable electronic vacuum chuck, including left support 2 and right support 3 installed respectively at the left and right ends of the top of base 1, the left side of left support 2 is fixedly installed with shell 5, the left end of the top of shell 5 is provided with display screen 6, the right end of the top of shell 5 is provided with three adjusting buttons 7 and one on-off button 8, the lower end of the inner chamber of shell 5 is provided with lithium battery 18, the top of the inner chamber of shell 5 is fixedly installed with control mainboard 19 corresponding with display screen 6, the upper end of the left side of shell 5 is provided with working indicator light 13 and charging socket 14. The top of the inner chamber of shell 5 is fixedly connected with supporting seat 16, the bottom of the inner side of supporting seat 16 is provided with multiple second pressure sensors 21 distributed at equal angles, the top of second pressure sensor 21 is provided with connecting disc 15, the upper end of connecting disc 15 is located at the inner side of supporting seat 16, the bottom of connecting disc 15 is fixedly installed with chuck main body 10, the top of the inner chamber of chuck main body 10 is fixedly installed with first pressure sensor 12, the middle end of the top of base 1 is provided with through slot 20, the corresponding position of the top of base 1 is provided with supporting disc 9, the middle end of the top of supporting disc 9 is fixedly installed with alarm lamp 11, the bottom of supporting disc 9 is fixedly installed with vacuum pump 17, the air inlet end of vacuum pump 17 is communicated with the middle end of the top of chuck main body 10 through pipeline.

[0025] This technical solution utilizes three adjustment buttons 7 to control the operating parameters of the vacuum pump 17 at high, medium, and low levels. This allows for adjustment of the suction force of the vacuum suction cup according to work requirements. After the operator moves the vacuum suction cup to the surface of the object to be suctioned, pressing the on / off button 8 powers the vacuum suction cup. Then, by selecting the appropriate suction force and pressing the corresponding adjustment button 7, the vacuum pump 17, with the assistance of the control motherboard 19 and the first pressure sensor 12, activates the corresponding suction force. The suction cup body 10 then adheres to the object's surface after generating negative pressure. The suction cup then moves the suctioned object, thus enabling object handling. During position transfer, the suction cup body 10 can compress the second pressure sensor 21 in the support seat 16 via the connecting plate 15, and the compressive force can be displayed on the display screen 6. If the weight of the object being adsorbed exceeds the adsorption limit of the suction cup body 10, the second pressure sensor 21 transmits the signal to the control motherboard 19 for processing. The control motherboard 19 can then turn on the alarm light 11 to warn the staff. At this time, the staff can press the adjustment button 7 to increase the working parameters of the vacuum pump 17 and strengthen the adsorption force of the suction cup body 10. If the highest level vacuum pump 17 still cannot eliminate the alarm light 11 warning, the staff needs to abandon the adsorption of the object to ensure safety when moving the object and to prevent the object from falling during handling.

[0026] It should be noted that the components of the display screen 6, adjustment button 7, on / off button 8, alarm light 11, first pressure sensor 12, working indicator light 13, charging port 14, vacuum pump 17, lithium battery 18, control motherboard 19, and second pressure sensor 21 can all be purchased directly from the market. At the same time, the circuit connection between the various components adopts the mature conventional methods in the existing technology. In addition, a venting solenoid valve is provided on one side of the suction cup body 10, so it will not be described in detail here.
