[0001] The utility model relates to the technical field of coating equipment, in particular to a shielding device and continuous coating equipment. Background Art

[0002] Continuous coating equipment can continuously realize the coating operation of coated parts, with faster production cycle and better effect. The existing continuous coating equipment is composed of multiple coating units, and the racks enter the arranged coating units in sequence to realize coating.

[0003] Since the coating chamber needs to be sealed and evacuated when a single coating unit is coating, a sealing gate valve is usually provided between two adjacent coating chambers. The coating chamber is sealed and opened by opening or closing the gate valve, thereby realizing the transportation of the hanger and the coating operation of the parts to be coated on the hanger.

[0004] However, the existing gate valves are also exposed to the coating environment of the coating chamber during coating. Since the ions precipitated in the coating chamber will escape, a large amount of adhesion will be generated on the outer surface of the gate valve after a long period of coating operation, affecting the sealing performance of the gate valve. The gate valve needs to be cleaned before it can be used again, which not only increases the cost of use, but also requires production to be stopped, greatly affecting the operating efficiency.

[0005] Therefore, there is an urgent need to provide a shielding device, namely a continuous coating device, to solve the problems existing in the prior art to a certain extent. Utility Model Content

[0011] Furthermore, the sealing mechanism also includes a sealing assembly, which includes a pressure ring and a third seal. A first mounting groove is formed in the extension portion, and the pressure ring and the third seal are both arranged in the first mounting groove, and the pressure ring and the third seal are both sleeved on the telescopic member. The pressure ring is used to compress the third seal, and the third seal is used to make a sealed connection between the telescopic member and the extension portion.

[0014] Furthermore, the sealing mechanism also includes a sleeve; a third installation groove is formed at one end of the extension portion located in the coating cavity, the sleeve is embedded in the third installation groove, and the telescopic member passes through the sleeve and enters the coating cavity.

[0015] Wherein, the shielding assembly includes a baffle and a connecting plate, the connecting plate is connected to one end of the telescopic member located in the coating chamber, and the baffle is connected to the connecting plate.

[0037] like Figure 1 Combination Figure 2 As shown, the utility model provides a shielding device for shielding a gate valve in a continuous coating device, comprising a driving mechanism, a sealing mechanism and a shielding assembly; the driving mechanism comprises a positioning assembly and a telescopic member 2, the positioning assembly is connected to the coating cavity of the continuous coating device, one end of the telescopic member 2 is located in the coating cavity, and can reciprocate in the coating cavity along the vertical direction; the shielding assembly is connected to one end of the telescopic member 2 located in the coating cavity, the sealing mechanism is sleeved on the telescopic member 2, and the sealing mechanism is sealed to the telescopic member 2, and the sealing mechanism is sealed to the coating cavity.

[0038] Compared with the prior art, the shielding device provided by the utility model has the following advantages:

[0039] The shielding device provided by the utility model is connected to the coating chamber of the continuous coating equipment through the positioning component of the driving mechanism, so as to realize the stable connection between the driving mechanism and the coating chamber, and provide a positioning basis for the movement of the telescopic member 2. By making one end of the telescopic member 2 located in the coating chamber and being able to reciprocate in the coating chamber in the vertical direction, the shielding component can be connected to the end of the telescopic member 2 located in the coating chamber, so as to realize the reciprocating movement of the shielding component in the coating chamber in the vertical direction.

[0040] Since the shielding component in the present application is arranged relative to the gate valve, when the shielding component rises, it can gradually cover the gate valve. When the shielding component rises to the extreme position, the gate valve can be completely covered. Therefore, when the coating operation is carried out, it can avoid the problem of ions precipitated in the coating chamber adhering to the gate valve and affecting the use of the gate valve to a certain extent.

[0041] When the coating is completed, the telescopic member 2 contracts, thereby driving the shielding component to move downward and leak out of the gate valve. After the gate valve is opened, the rack in the coating chamber can be moved.

[0042] Accordingly, since the telescopic member 2 in the present application needs to pass through the coating cavity, a sealing mechanism is sleeved on the telescopic member 2, and the sealing mechanism is sealedly connected to the telescopic member 2 and the coating cavity at the same time, so that the sealing between the telescopic member 2 and the coating cavity can be achieved, thereby avoiding leakage when the coating cavity is evacuated.

[0043] It can be understood that when the shielding device provided by the present application is used in a continuous coating equipment, when the hanger needs to be moved, the telescopic member 2 contracts, driving the shielding component to move downward and leak out of the gate valve. After that, the gate valve opens, and the hanger in the previous coating cavity enters the adjacent subsequent coating cavity. After it is in place, the gate valve closes, and the telescopic member 2 extends, driving the shielding member to rise and cover the gate valve. After everything is covered, the coating operation begins.

[0044] When the coating operation is completed, the telescopic member 2 retracts, driving the shielding assembly to move downward, the gate valve opens, and the rack moves to the next coating chamber again, and the above actions are repeated to achieve continuous coating operation of the workpiece.

[0045] It should be noted here that the driving mechanism in the present application can adopt an air cylinder or an oil cylinder. Preferably, an air cylinder is used, the cylinder body of the cylinder is connected to the coating cavity, one end of the telescopic rod protruding from the cylinder body extends into the coating cavity, and the telescopic rod can slide relative to the coating cavity to realize the reciprocating motion of the shielding component in the vertical direction.

[0046] Alternatively, if Figure 1 Combination Figure 2 As shown, the positioning assembly in the present application includes a positioning cylinder 1, a connecting member 4 and a mounting member 3; the positioning cylinder 1 is connected to the connecting member 4, the connecting member 4 is connected to the mounting member 3, and the mounting member 3 is connected to the outer wall of the coating chamber.

[0047] Since the driving mechanism in the present application adopts a cylinder, the positioning cylinder 1 in the present application is the cylinder body of the cylinder, the telescopic rod is located in the cylinder body, the connecting member 4 is the cylinder flange, and the mounting member 3 is the mounting flange. Since the positioning cylinder 1 is connected to the connecting member 4, the connecting member 4 is connected to the mounting member 3, that is, the cylinder flange is connected to the mounting flange, and the mounting flange is connected to the coating cavity, so that a stable connection between the positioning cylinder 1 and the coating cavity can be achieved, thereby providing a stable positioning basis for the reciprocating motion of the telescopic rod in the vertical direction.

[0048] Preferably, if Figure 1 Combination Figure 2 As shown, the mounting component 3 in the present application forms a receiving groove at the position corresponding to the coating cavity, and a first sealing member 6 is provided in the receiving groove. The first sealing member 6 is located between the mounting component 3 and the coating cavity, so that the mounting component 3 is sealed and connected to the coating cavity.

[0049] The first seal 6 in the present application is a sealing ring. A receiving groove formed on the mounting component 3 corresponding to the coating cavity position can provide an installation basis for the first seal 6. The first seal 6 is arranged between the mounting component 3 and the coating cavity, and a sealed connection between the mounting component 3 and the coating cavity can be achieved.

[0050] It can be understood that since a cylinder is used in the present application, and the telescopic rod of the cylinder needs to be extended into the coating cavity, and the coating cavity needs to ensure the sealing blockage inside the cavity when evacuating the vacuum, therefore, the corresponding positions of the telescopic rod and the positioning cylinder 1 need to be sealed. The present application can achieve a sealed connection between the connecting position of the mounting component 3 and the coating cavity by setting a first sealing member 6 between the mounting component 3 and the coating cavity.

[0051] It should be noted here that in the continuous coating equipment, the coating chamber is mainly formed by the docking of the first cavity and the second cavity. The space corresponding to the first cavity is used for coating operations, and structures such as the hanger and the gate valve are located in the space corresponding to the first cavity, while the space corresponding to the second cavity is used to set up the power mechanism, control mechanism and structures such as the shielding assembly provided in this application.

[0052] Therefore, when the coating operation is carried out, the cylinder in the present application extends, driving the shielding assembly from the second cavity into the first cavity to shield the gate valve. When the coating is completed and the rack needs to be transported, the cylinder contracts, driving the shielding assembly into the second cavity, thereby exposing the gate valve and realizing the transportation of the rack.

[0053] It is understandable that if Figure 1 As shown, the second cavity in the present application is formed by assembling a cavity body 14 and a mounting member 3, and the cavity body 14 is cylindrical, one end of which is connected to the mounting member 3, and the other end is connected to the first cavity, thereby forming the above-mentioned coating cavity. Therefore, the sealing of the second cavity can be achieved by the first sealing member 6.

[0054] Alternatively, if Figure 1 Combination Figure 2 As shown, the sealing mechanism in the present application includes a sealing seat 5 and a second sealing member 7; a positioning groove is formed on the side of the connecting member 4 facing the coating cavity, and the sealing seat 5 includes a base portion and an extension portion, the base portion is embedded in the positioning groove, and the base portion is connected to the mounting member 3; a positioning portion is formed on the outer ring wall surface of the base portion, the second sealing member 7 is mounted on the positioning portion, and the second sealing member 7 is located between the positioning portion and the mounting member 3; the extension portion passes through the mounting member 3 and enters the coating cavity, and the telescopic member 2 passes through the extension portion and enters the coating cavity.

[0055] By forming a positioning groove on the side of the connecting member 4 facing the coating cavity, the base portion of the sealing seat 5 can be accommodated. Since the extension portion of the sealing seat 5 in the present application needs to pass through the mounting member 3 to enter the coating cavity, the present application connects the sealing seat 5 with the mounting member 3, and a positioning portion for setting the second sealing member 7 is formed on the outer ring wall surface of the base portion, so that the second sealing member 7 can be stably set between the base portion and the mounting member 3, thereby ensuring the sealing performance between the sealing seat 5 and the mounting member 3.

[0056] Correspondingly, by allowing the telescopic member 2 to pass through the extension portion, the movement of the telescopic member 2 in the coating chamber can be achieved and the sealing performance during the movement can be ensured.

[0057] Alternatively, if Figure 1 Combination Figure 2 As shown, the sealing mechanism also includes a sealing assembly, which includes a pressure ring 9 and a third sealing member 8. A first mounting groove is formed in the extension portion, and the pressure ring 9 and the third sealing member 8 are both arranged in the first mounting groove. The pressure ring 9 and the third sealing member 8 are both sleeved on the telescopic member 2. The pressure ring 9 is used to compress the third sealing member 8, and the third sealing member 8 is used to make the telescopic member 2 and the extension portion sealed.

[0058] Based on the above structure, the present application provides an implementation method for achieving a sealed connection between the telescopic member 2 and the sealing seat 5 while achieving the sliding of the telescopic member 2 relative to the sealing seat 5. Specifically, a first mounting groove is formed in the extension portion, and a sealing assembly is arranged in the first mounting groove. The sealing assembly in the present application includes a pressure ring 9 and a third sealing member 8. The third sealing member 8 and the pressure ring 9 are both sleeved on the telescopic member 2, so that the pressure ring 9 can prevent the third sealing member 8 from moving in the axial direction, and the sliding and sealing between the telescopic member 2 and the extension portion can be achieved by the third sealing ring.

[0059] Preferably, if Figure 1 Combination Figure 2 As shown, there are multiple sealing assemblies in the present application, and the multiple sealing assemblies are arranged in sequence along the axial direction of the telescopic member 2. By arranging multiple sealing assemblies, the sealing performance between the telescopic member 2 and the sealing seat 5 can be further improved.

[0060] like Figure 2 As shown, the number of sealing assemblies in the present application is three, and each of them includes a third sealing member 8 and a pressure ring 9. By sequentially arranging the three sealing assemblies, the sealing degree between the telescopic member 2 and the sealing seat 5 can be improved to a certain extent.

[0061] Alternatively, if Figure 1 Combination Figure 2As shown, the sealing mechanism in the present application also includes a pressure cover 10, a second mounting groove is formed on the base part, the second mounting groove is connected to the first mounting groove, the pressure cover 10 is arranged in the second mounting groove, and the pressure cover 10 is connected to the sealing seat 5, and the pressure cover 10 is used to press the sealing component arranged in the first mounting groove.

[0062] By forming a second mounting groove on the base part and communicating with the first mounting groove, and arranging a pressure cover 10 in the second mounting groove, the sealing component in the first mounting groove can be limited, ensuring that the sealing component can be stably located in the first mounting groove, thereby ensuring the sealing effect.

[0063] Alternatively, if Figure 1 As shown, the sealing mechanism in the present application further includes a sleeve 11; a third mounting groove is formed at one end of the extension portion located in the coating cavity, the sleeve 11 is embedded in the third mounting groove, and the telescopic member 2 passes through the sleeve 11 into the coating cavity.

[0064] The second mounting groove provided in the extension portion can provide a mounting base for the shaft sleeve 11 , and the further provided shaft sleeve 11 can further improve the sealing performance, thereby ensuring the sealing effect in the coating cavity.

[0065] Alternatively, if Figure 1 As shown, the shielding assembly in the present application includes a baffle 13 and a connecting plate 12 . The connecting plate 12 is connected to one end of the telescopic member 2 located in the coating cavity, and the baffle 13 is connected to the connecting plate 12 .

[0066] The connecting plate 12 can provide a larger connection area for the baffle 13, thereby ensuring the connection stability of the baffle 13 to a certain extent, thereby achieving stable operation of the entire device.

[0067] Preferably, if Figure 1 As shown, the mounting member 3 in the present application is also connected to a guide rod 15 on the side facing the coating chamber, the guide rod 15 extends in the vertical direction, and the guide rod 15 passes through the baffle 13, so that the baffle 13 can be guided by the guide rod 15 to avoid the baffle 13 from shaking during movement, which may cause damage to the telescopic member 2.

[0068] In addition, the utility model also provides a continuous coating device, including a plurality of coating chambers connected in sequence, a gate valve located between two adjacent coating chambers, and the above-mentioned shielding device, wherein an inlet and an outlet are respectively formed at both ends of the coating chamber, and the inlet and outlet of the coating chamber are both provided with the above-mentioned shielding device.

[0069] The continuous coating equipment using the shielding device provided by the present application can shield the gate valve by arranging shielding devices at the inlet and outlet of the coating chamber, thereby reducing the impact on the gate valve during coating to a certain extent, increasing the service life of the gate valve, reducing the number of cleaning times of the gate valve, reducing the cost of use, and improving operating efficiency.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
