Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum controllers, and more particularly to a vacuum controller. Background Technology
[0002] A vacuum controller is a device that monitors, regulates, and stabilizes the pressure within a vacuum system in real time through sensors, actuators, and a control system. It can drive valves or pumps to adjust the pumping / intake volume through logic such as PID control algorithms, achieving precise vacuum control. It is used because it can meet the high-precision vacuum requirements of semiconductor manufacturing, scientific research experiments, and other scenarios, adapt to the dynamic adjustment needs of multi-stage vacuum processes, and improve system safety through overload protection and abnormal alarms. At the same time, it can achieve energy saving and efficiency improvement through automated operation and power regulation. It is a key component in modern vacuum technology to ensure stable system operation and improve process accuracy and production efficiency.
[0003] Existing vacuum controllers operate based on closed-loop feedback control theory. First, a pressure sensor converts the pressure within the vacuum system into an electrical signal. The core processor receives the signal and compares it with a preset target value. It then uses algorithms such as PID to calculate the deviation and drives actuators such as the intake valve, exhaust valve, and vacuum pump to adjust the gas flow or pumping efficiency, thereby adjusting the vacuum level. After adjustment, the sensor collects data again, forming a cycle of detection-control-adjustment-re-detection. It also supports human-machine interaction and communication integration to ensure high-precision and stable vacuum control, meeting the needs of different scenarios.
[0004] In practical applications of vacuum controllers, the operating efficiency of the equipment is often limited by the difficulty of connecting the gas supply pipe and the ventilation pipe. Existing designs mostly use traditional methods such as threaded connections and flange connections. Operators need to precisely align the interfaces, tighten multiple sets of bolts, or apply sealant. Not only are the operation steps cumbersome, but tools are also required. Especially in confined spaces or high vacuum environments, the connection accuracy requirements are even higher. Even a slight deviation can lead to air leakage or seal failure. In addition, frequent disassembly and assembly can easily cause interface wear and increase maintenance costs. The complex connection process often takes several minutes to tens of minutes, which seriously affects the efficiency of production line changeover or the continuity of experiments. This contradiction between the complexity of the front-end connection and the high precision of the back-end control has become a significant pain point restricting the efficient application of vacuum controllers.

[0032] 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.
[0033] Reference Figures 1-3 The present invention provides an embodiment of a vacuum controller, comprising a controller 1, a display screen 2 electrically connected to the top of the controller 1 for displaying data inside the controller 1, a communication interface 3 electrically connected to one side of the controller 1 for connecting a communication line, a connection component provided on one side of the controller 1 for connecting other lines, a vent pipe 8 fixedly connected to one side of the controller 1 for supplying air, a fixing component provided on the outer wall of the vent pipe 8 for fixing a gas delivery pipe 14, a gas delivery pipe 14 slidably connected inside the vent pipe 8 for transporting air, and a fixing groove 15 provided on the outer wall of the gas delivery pipe 14 for accommodating ball bearings 13;
[0034] The fixing assembly includes a sliding sleeve 9, a spring 11, and multiple balls 13. The inner wall of the sliding sleeve 9 is slidably connected to the outer wall of the vent pipe 8 to control the unlocking and fixing of the balls 13. The spring 11 is disposed inside the sliding sleeve 9 to provide elastic force to the sliding sleeve 9. One end of the spring 11 is fixedly connected to the inside of the sliding sleeve 9, and the other end of the spring 11 is fixedly connected to the outer wall of the vent pipe 8. The outer wall of each ball 13 is slidably connected to the inside of the vent pipe 8 to control the unlocking and fixing of the air supply pipe 14. A retaining ring 10 is fixedly connected to the outer wall of the vent pipe 8 to limit the sliding sleeve. The movement range of 9, the ventilation pipe 8 has multiple sliding grooves 12 inside to accommodate the ball bearings 13, the connection components include load interface 4, vacuum pump connector 5, output power socket 6 and input power socket 7, one end of load interface 4 is electrically connected to one side of controller 1 for connecting the load line, one end of vacuum pump connector 5 is fixedly connected to one side of controller 1 for connecting the vacuum pump, one side of output power socket 6 is electrically connected to one side of controller 1 for connecting the output wire, one side of input power socket 7 is electrically connected to one side of controller 1 for connecting the input wire;
[0035] Specifically, when connecting the air supply tube 14 and the ventilation tube 8, first firmly grasp the sliding sleeve 9 with your palm and push it inward with a little force. As the sliding sleeve 9 moves, the ball bearing 13, which was originally embedded in the slot and played a fixing role, is unlocked. Then, grasp the air supply tube 14 with your other hand, align its front end with the entrance of the ventilation tube 8, and smoothly insert it into the ventilation tube 8. When the air supply tube 14 is in place, release your hand that is tightly gripping the sliding sleeve 9. Under the action of the spring 11, the sliding sleeve 9 quickly pops outward. Its internal structure pushes the ball bearing 13 in turn, so that the ball bearing 13 slides into the fixing groove 15 inside the inner wall of the air supply tube 14, so that the air supply tube 14 is firmly locked. The whole connection process is completed in one go, which is both efficient and reliable.
[0036] Reference Figure 4 and Figure 5The controller 1 has multiple connecting posts 16 fixedly connected to its bottom for connecting support posts 18. Each connecting post 16 has multiple connecting holes 17 on its outer wall for accommodating fixing pins 20. Each connecting post 16 has a support post 18 slidably connected inside for supporting the controller 1. Each support post 18 has a support plate 19 fixedly connected to its bottom for supporting the entire device. Each support post 18 has a fixing pin 20 slidably connected inside for fixing the height of the support post 18. Each fixing pin 20 has a blocking pin 21 slidably connected inside for preventing the fixing pin 20 from sliding out of the support plate. Each of the support columns 18 and the outer wall of each blocking pin 21 is fixedly connected to a limiting plate 22 to limit the movement range of the blocking pin 21. The outer wall of each limiting plate 22 is slidably connected to the inside of the fixing pin 20. Each fixing pin 20 is provided with a second spring 23 to provide elastic force for the blocking pin 21. One end of each second spring 23 is fixedly connected to the inside of the fixing pin 20, and the other end of each second spring 23 is fixedly connected to one side of the blocking pin 21. The connecting columns 16 are arranged in a symmetrical array at the bottom of the controller 1, and the connecting holes 17 are arranged in a parallel array inside the connecting columns 16.
[0037] Specifically, when the height of the support column 18 needs to be adjusted, the user first gently presses the blocking pin 21 with their finger. As pressure is applied, the blocking pin 21 slowly retracts into the fixing pin 20, and the original locking structure is instantly released. Then, the user presses the palm against the fixing pin 20 and pulls it out smoothly. As the fixing pin 20 disengages from the connecting hole 17, the support column 18 is completely freed from its restraint. At this time, the user holds the support column 18 with both hands and raises or lowers it to the target height according to actual usage needs. Finally, the user aligns the fixing pin 20 with the corresponding connecting hole 17 and inserts it. As the fixing pin 20 and the connecting hole 17 fit tightly together, the blocking pin 21 pops out and locks the fixing pin 20 under the action of the internal spring 23, thus completing the height adjustment of the support column 18. The entire process is smooth and the positioning is stable and reliable.
[0038] Working principle: When using the vacuum controller, first hold the sliding sleeve 9 and push it inward to unlock the ball bearing 13. Then hold the air supply pipe 14 and insert its front end into the air pipe 8. After that, release the sliding sleeve 9 so that it pops out under the action of the spring 11 and pushes the ball bearing 13 into the fixing groove 15 to fix the air supply pipe 14. Then start the controller 1 using the display screen 2. When it is necessary to adjust the height of the support column 18, first press the blocking pin 21 to retract it into the fixing pin 20 to unlock the fixing pin 20. Then hold the fixing pin 20 and pull it out to unlock the support column 18. After that, hold the support column 18 and adjust its height to the required height. Then reinsert the fixing pin 20 into the corresponding connection hole 17 to complete the height adjustment of the support column 18.
[0039] Finally, it should be noted that the above description 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 foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
