Description

Technical Field

[0001] This utility model relates to the technical field of vacuuming in coating processes, and in particular to a high-efficiency, low-consumption vacuuming system for coating machines. Background Technology

[0002] Current coating machines use vacuum pumping components to evacuate the coating chamber. However, during each workpiece loading and unloading for coating, the vacuum in the coating chamber needs to be released to break the vacuum, the finished workpiece is removed, and a new workpiece is loaded. Then, the vacuum pumping components are used to evacuate the chamber again. In this process, firstly, the vacuum pumping components have difficulty quickly evacuating the coating chamber to the set vacuum level, resulting in low coating efficiency. Secondly, it also prolongs the running time of the vacuum pumping components, increasing energy consumption. Utility Model Content

[0003] The purpose of this utility model is to provide a high-efficiency, low-consumption vacuum system for coating machines, so as to solve one or more technical problems existing in the prior art, or at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows:

[0005] This utility model provides a high-efficiency, low-consumption vacuum system for a coating machine, comprising:

[0006] Coating chamber;

[0007] The vacuum assembly is provided with a vacuum end connected to the coating chamber, and the vacuum assembly is used to evacuate the interior of the coating chamber.

[0008] A pressure storage chamber is connected to the coating chamber, and a control valve is provided between the pressure storage chamber and the coating chamber. The control valve is used to control the on / off connection between the pressure storage chamber and the coating chamber.

[0009] The beneficial effects of the high-efficiency, low-consumption vacuum system for coating machines of this utility model are:

[0010] During operation, the vacuum assembly evacuates the coating chamber to the required vacuum level. Before removing the finished workpiece, i.e., before breaking the vacuum in the coating chamber, the control valve is opened to connect the pressure storage chamber and the coating chamber. This disperses the negative pressure in the coating chamber into the pressure storage chamber, effectively evacuating it. Once the pressures in the coating chamber and the pressure storage chamber are balanced, the control valve is closed, breaking the vacuum in the coating chamber. When the vacuum in the coating chamber is re-established... First, the control valve is opened, and the coating chamber is pre-vacuumed through the pressure storage chamber to balance the pressure inside the coating chamber and the pressure storage chamber. Then, the control valve is closed, and the coating chamber is evacuated through the vacuum pumping assembly. This cycle is repeated. This invention uses the pressure storage chamber to temporarily store the vacuum in the coating chamber instead of directly releasing the pressure. This allows the coating chamber to be quickly evacuated to the set vacuum level before the vacuum pumping assembly is connected to the mains pipe for further evacuation, improving the vacuuming efficiency of the coating chamber and reducing energy consumption.

[0011] As a further improvement to the above technical solution, a connecting pipe is provided between the pressure storage chamber and the coating chamber, and the control valve is installed on the connecting pipe.

[0012] As a further improvement to the above technical solution, multiple control valves are provided, and the multiple control valves are arranged along the connecting pipeline.

[0013] As a further improvement to the above technical solution, the pressure storage chamber is provided with a pre-vacuuming mechanism, which is used to evacuate the interior of the pressure storage chamber.

[0014] As a further improvement to the above technical solution, the vacuum pumping assembly is provided with two pumping ends, which are respectively connected to the pressure storage chamber and the coating chamber. The vacuum pumping assembly is also used to evacuate the interior of the pressure storage chamber.

[0015] As a further improvement to the above technical solution, the pressure storage chamber is equipped with a first pressure sensor for detecting the internal vacuum level.

[0016] As a further improvement to the above technical solution, the pressure storage chamber is equipped with a second pressure sensor for detecting the internal vacuum level.

[0017] As a further improvement to the above technical solution, the coating chamber is provided with an air inlet that communicates with the outside, and the air inlet is provided with an air valve.

[0018] Furthermore, this utility model also proposes an operating method applicable to the vacuum system of the high-efficiency, low-consumption coating machine, the operating method comprising:

[0019] The interior of the coating chamber is evacuated to achieve a preset vacuum level.

[0020] Before breaking the vacuum of the coating chamber, the control valve is opened to connect the pressure storage chamber with the coating chamber, thereby pre-breaking the vacuum of the coating chamber.

[0021] Once the vacuum levels of the pressure storage chamber and the coating chamber are balanced, the control valve is closed to break the vacuum level of the coating chamber.

[0022] When the coating chamber is evacuated, the control valve is opened to connect the pressure storage chamber with the coating chamber, and the coating chamber is pre-evacuated.

[0023] Once the vacuum levels of the pressure storage chamber and the coating chamber are balanced, the control valve is closed to evacuate the interior of the coating chamber.

[0024] As a further improvement to the above technical solution, the operating method further includes:

[0025] When the vacuum level of the coating chamber is broken and the control valve is closed, the pressure storage chamber is evacuated.

[0026] Other features and advantages of this invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. Attached Figure Description

[0043] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0044] Current coating machine vacuum systems use a vacuum assembly 200 to evacuate the coating chamber 100. However, during each workpiece loading and unloading for coating, the vacuum in the coating chamber 100 needs to be released to break the vacuum, the finished workpiece is removed, and a new workpiece is loaded. Then, the vacuum assembly 200 is used to evacuate the vacuum again. In this process, firstly, the vacuum assembly 200 has difficulty quickly evacuating the coating chamber 100 to the set vacuum level, resulting in low coating efficiency. Secondly, it also prolongs the running time of the vacuum assembly 200, increasing energy consumption. Therefore, this utility model proposes a high-efficiency, low-energy-consumption vacuum system for coating machines.

[0045] like Figure 1 As shown, the high-efficiency, low-consumption coating machine vacuum system of this embodiment includes a coating chamber 100, a vacuum assembly 200, and a pressure storage chamber 300.

[0046] The coating chamber 100 serves as the place for coating the workpiece. The coating chamber 100 is equipped with a door, which is opened to load and unload the workpiece.

[0047] The vacuum assembly 200 is provided with an air extraction end connected to the coating chamber 100. The vacuum assembly 200 is used to evacuate the interior of the coating chamber 100. The vacuum assembly 200 is a conventional coating vacuum equipment.

[0048] The pressure storage chamber 300 is connected to the coating chamber 100. A control valve 400 is provided between the pressure storage chamber 300 and the coating chamber 100. The control valve 400 is used to control the opening and closing of the pressure storage chamber 300 and the coating chamber 100. The pressure storage chamber 300 is used to store the vacuum pressure inside the coating chamber 100.

[0049] During use, the vacuum assembly 200 evacuates the interior of the coating chamber 100 to the required vacuum level. Before removing the finished workpiece, i.e., before breaking the vacuum in the coating chamber 100, the control valve 400 is opened to connect the pressure storage chamber 300 with the coating chamber 100. At this time, the negative vacuum pressure in the coating chamber 100 is dispersed into the pressure storage chamber 300, thus evacuating its interior. Once the pressures in the coating chamber 100 and the pressure storage chamber 300 are balanced, the control valve 400 is closed, breaking the vacuum in the coating chamber 100 and connecting it to the outside. When the vacuum in the coating chamber 100 is re-established... First, the control valve 400 is opened, and the coating chamber 100 is pre-evacuated through the pressure storage chamber 300 to balance the pressure inside the coating chamber 100 and the pressure storage chamber 300. Then, the control valve 400 is closed, and a certain vacuum is formed inside the coating chamber 100. Then, the vacuum pumping assembly 200 is used to evacuate the inside of the coating chamber 100. This cycle is repeated. This utility model uses the pressure storage chamber 300 to temporarily store the vacuum in the coating chamber 100 instead of directly releasing the pressure. It can quickly evacuate the coating chamber 100 to the set vacuum level before the vacuum pumping assembly 200 is connected to the pipe to perform vacuuming, which improves the vacuuming efficiency of the coating chamber 100 and reduces energy consumption.

[0050] In this embodiment, a connecting pipe 500 is provided between the pressure storage chamber 300 and the coating chamber 100, and a control valve 400 is installed on the connecting pipe 500. After the control valve 400 is opened, the pressure storage chamber 300 and the coating chamber 100 are connected together through the connecting pipe 500.

[0051] To improve the sealing between the pressure storage chamber 300 and the coating chamber 100, multiple control valves 400 can be provided. Multiple control valves 400 are provided along the connecting pipe 500. In this embodiment, two control valves 400 are provided.

[0052] In some other embodiments, the pressure storage chamber 300 is provided with a pre-vacuuming mechanism, which is used to evacuate the interior of the pressure storage chamber 300. The pre-vacuuming mechanism operates when the pressure storage chamber 300 stores the vacuum in the coating chamber 100 and the control valve 400 is closed. Considering that this time period is for loading and unloading workpieces, the pre-vacuuming mechanism can be used to evacuate the interior of the pressure storage chamber 300. This time period can be used to further evacuate the interior of the pressure storage chamber 300. When the pressure storage chamber 300 is connected to the coating chamber 100, the balanced vacuum degree between the pressure storage chamber 300 and the coating chamber 100 can be improved, thereby further accelerating the efficiency of evacuating the coating chamber 100.

[0053] The pre-vacuuming mechanism can use a low-power vacuum pump.

[0054] In some other embodiments, the vacuum assembly 200 is provided with two suction ends, which are respectively connected to the pressure storage chamber 300 and the coating chamber 100. The vacuum assembly 200 is also used to evacuate the interior of the pressure storage chamber 300. It can be understood that when the coating chamber 100 is being loaded or unloaded, the vacuum assembly 200 can evacuate the pressure storage chamber 300, and this loading or unloading time period is also utilized.

[0055] In this embodiment, the pressure storage chamber 300 is provided with a first pressure sensor for detecting the internal vacuum level, and the pressure storage chamber 300 is provided with a second pressure sensor for detecting the internal vacuum level, so as to realize automatic control.

[0056] In this embodiment, the coating chamber 100 is provided with an air inlet that communicates with the outside. The air inlet is provided with an air valve, and the vacuum of the coating chamber 100 is broken by controlling the opening of the air valve.

[0057] Furthermore, this utility model also proposes an operating method applicable to the vacuum system of a high-efficiency, low-consumption coating machine. The operating method includes the following steps:

[0058] Step S100: Evacuate the interior of the coating chamber 100 to achieve a preset vacuum level, such as... Figure 2 As shown;

[0059] Step S200: Before breaking the vacuum in the coating chamber 100, open the control valve 400 to connect the pressure storage chamber 300 with the coating chamber 100, thus pre-breaking the vacuum in the coating chamber 100. Figure 3 As shown;

[0060] Step S300: After the vacuum levels of the pressure storage chamber 300 and the coating chamber 100 are balanced, the control valve 400 is closed to break the vacuum level of the coating chamber 100.

[0061] Step S400: When evacuating the coating chamber 100, open the control valve 400 to connect the pressure storage chamber 300 with the coating chamber 100, and pre-evacuate the coating chamber 100, as shown below. Figure 4 As shown;

[0062] Step S500: After the vacuum levels in the pressure storage chamber 300 and the coating chamber 100 are balanced, close the control valve 400 to evacuate the interior of the coating chamber 100. Figure 2 As shown.

[0063] In some other embodiments, the method of operation further includes:

[0064] Step S310: When the vacuum level of the coating chamber 100 is broken and the control valve 400 is closed, the pressure storage chamber 300 is evacuated. At this time, the pressure storage chamber 300 is evacuated by the vacuum pumping assembly 200 or the pre-vacuum pumping mechanism.
