Description

Technical Field

[0001] This invention relates to the field of vacuum activation technology for coated parts, and in particular to a method and apparatus for detecting leaks during vacuum activation of coated parts. Background Technology

[0002] Wrapped components have wide applications in many fields, especially in automotive interior design where they play a crucial role. For example, wrapping processes are often used on car dashboards, door panels, and seats to enhance the overall aesthetics and comfort of the interior.

[0003] Existing vacuum activation machines are designed to bond adhesive-coated decorative materials to each other by pressing them point-by-point with pressure rollers and forming wheels as the profile moves in the conveying direction. However, existing vacuum activation machines have excessively long coating times for the activation mold, leading to a decrease or even failure of the adhesive's bonding performance. They also easily result in situations where the coated areas are not properly pressed or are not properly sealed, causing issues such as delamination or blistering. This not only fails to guarantee product quality and reduces production efficiency but also increases production costs. Furthermore, it is difficult to effectively identify whether the vacuum adsorption process has been completed on the finished coated parts.

[0004] Therefore, there is an urgent need to provide a vacuum activation device for coating parts to create a vacuum environment for vacuum activation treatment of coating parts, and to provide a leak-proof detection method for vacuum activation of coating parts to detect and identify whether the coating parts have completed the vacuum activation process. Summary of the Invention

[0005] The purpose of this invention is to provide a method and apparatus for detecting leaks during vacuum activation of coated parts, which solves the problem that the vacuum activation process of coated parts in the prior art is poor and that the coated parts cannot be effectively identified as having completed the vacuum adsorption process.

[0006] To achieve the above objectives, the present invention provides a vacuum activation device for a coating, comprising a vacuum adsorption membrane and a coating, wherein the vacuum adsorption membrane cooperates with the coating.

[0007] It also includes a vacuum-activated leak detection component;

[0008] The vacuum activation leak-proof detection assembly includes a support platform, an adsorption detection chamber, a mold connecting plate, a pneumatic control component, and a vacuum pump component. The adsorption detection chamber is fixedly installed on the top of the support platform. The mold connecting plate is connected to the support platform through the pneumatic control component and is located directly above the adsorption detection chamber, and is fixedly connected to the vacuum adsorption membrane. The pneumatic control component is fixedly connected to the mold connecting plate and drives the mold connecting plate to move up and down. The vacuum pump component is connected to the adsorption detection chamber and installed on the support platform.

[0009] The vacuum pump component includes a mounting plate, a vacuum pump, and a vacuum pipe. The mounting plate is fixedly connected to the support platform and is located between two support plates at the bottom of the support platform. The vacuum pump is fixedly connected to the mounting plate and is located at the top of the mounting plate. One end of the vacuum pipe is fixedly connected to the suction end of the vacuum pump, and the other end of the vacuum pipe is connected to the inner cavity of the adsorption detection chamber.

[0010] The vacuum pump component also includes a vacuum level detector, which is fixedly connected to the adsorption detection chamber and located on the inner wall of the adsorption detection chamber.

[0011] The mold connecting plate also includes a sealing strip, which is fixedly installed at the bottom of the mold connecting plate and cooperates with the top of the adsorption detection box.

[0012] The pneumatic control component includes a mounting frame, a pneumatic telescopic rod, and a limiting rod. The mounting frame is fixedly connected to the support platform by bolts and is positioned in the middle of the adsorption detection box. The pneumatic telescopic rod is fixedly installed on the mounting frame, and its output end is fixedly connected to the mold connecting plate. The limiting rod is fixedly connected to the mold connecting plate and is located on both sides of the pneumatic telescopic rod.

[0013] The mounting bracket has a mounting hole and a limiting hole. The mounting hole is located at the top center of the mounting bracket and extends through the mounting bracket. The limiting hole extends through both ends of the top of the mounting bracket and cooperates with the limiting rod.

[0014] The vacuum activation leak-proof detection assembly further includes a fixing component, which is disposed on the left and right sides of the adsorption detection chamber and extends partially into the inner cavity of the adsorption detection chamber.

[0015] The fixing component includes a clamping cylinder and a pressing rubber plate. There are two clamping cylinders, which are fixedly installed on the left and right sides of the outside of the adsorption detection box. The output end of the clamping cylinder extends into the adsorption detection box. The pressing rubber plate is fixedly connected to the output end of the clamping cylinder and is located inside the adsorption detection box.

[0016] This invention also provides a method for detecting leaks during vacuum activation of coated parts, applied to the aforementioned vacuum activation device for coated parts, comprising the following steps:

[0017] A dimple is added to the vacuum-adsorbed membrane to ensure that the dimple is clearly visible;

[0018] The coating is fixedly placed inside the adsorption detection chamber, and the coating material is placed on the coating.

[0019] The pneumatic control component drives the mold connecting plate to move downward, causing the vacuum adsorption membrane to extend into the adsorption detection chamber and seal the adsorption detection chamber.

[0020] The vacuum pump component is activated to extract the air from the adsorption detection chamber, creating a vacuum environment, and the coating material is vacuum adsorbed onto the coating component.

[0021] After vacuum adsorption is completed, the vacuum pump component is turned off, and the vacuum pressure inside the adsorption detection chamber is released, and the coating is removed.

[0022] Use a bump detection instrument, visual inspection, or touch to check whether bumps have formed on the covered part, thereby determining whether the covering process is complete.

[0023] This invention discloses a vacuum activation leak-proof detection method and apparatus for coated parts. The coated part is fixedly placed inside an adsorption detection chamber. Coating material is then placed on the coated part. The start-up control component is activated to drive the mold connecting plate downwards. The mold connecting plate drives the vacuum adsorption membrane downwards until it is in contact with the coated part. The mold connecting plate seals the upper end of the adsorption detection chamber. Then, the vacuum pump component is activated to create a vacuum environment inside the adsorption detection chamber, allowing the coating material to be vacuum adsorbed onto the coated part. After vacuum adsorption is complete, the vacuum pump component is turned off, and the vacuum pressure inside the adsorption detection chamber is released. The mold connecting plate is then opened to drive the coated part. Whether protrusions have formed on the coated part is determined by checking with a protrusion detection instrument, visual inspection, or touch, thereby determining whether the coating process is complete. The vacuum activation device for the coated part realizes the vacuum adsorption process and facilitates the determination of whether the adsorption process was completed. Attached Figure Description

[0032] First embodiment of this application:

[0033] Please see Figures 1 to 2 ,in Figure 1 This is a schematic diagram of the structure of the vacuum activation device for the coating component according to the first embodiment of the present invention. Figure 2 This is a connection diagram of the vacuum activation device for the coating component according to the first embodiment of the present invention.

[0034] This invention provides a vacuum activation device for a coating, comprising a vacuum adsorption membrane 101, a coating 102, and a vacuum activation leak-proof detection component. The vacuum activation leak-proof detection component includes a support platform 103, an adsorption detection chamber 104, a mold connecting plate 105, a pneumatic control component, and a vacuum pump 113 component. The vacuum pump 113 component includes a mounting plate 112, a vacuum pump 113, a vacuum pipe 114, and a vacuum degree detector 115. The mold connecting plate 105 also includes a sealing strip 106. The pneumatic control component includes a mounting frame 107, a pneumatic telescopic rod 108, and a limiting rod 109. The mounting frame 107 has a mounting hole 110 and a limiting hole 111.

[0035] In this embodiment, the vacuum adsorption membrane 101 cooperates with the covering component 102; the adsorption detection box 104 is fixedly installed on the top of the support platform 103; the mold connecting plate 105 is connected to the support platform 103 through the pneumatic control component, and is located directly above the adsorption detection box 104, and is fixedly connected to the vacuum adsorption membrane 101; the pneumatic control component is fixedly connected to the mold connecting plate 105, and drives the mold connecting plate 105 to move up and down; the vacuum pump 113 component is connected to the adsorption detection box 104 and installed on the support platform 103. The vacuum adsorption membrane 101 is a customized model based on the shape and size of the covering 102, providing a precise surface to ensure the covering material adheres tightly and maintains a stable shape during vacuum adsorption. The vacuum adsorption membrane 101 has a small indentation for detecting the presence of adsorption protrusions on the covering 102 after vacuum adsorption, thus identifying whether the vacuum activation process is complete. The vacuum adsorption membrane 101 is fixedly installed at the bottom center of the mold connecting plate 105. The top of the mold connecting plate 105 is connected via a pneumatic control component. This pneumatic control component accurately aligns the vacuum adsorption membrane 101 with the center of the adsorption detection chamber 104. The pneumatic control component drives the mold connecting plate 105 to move the vacuum adsorption membrane 101 vertically upwards or downwards, aligning it with the covering 102 fixed within the adsorption detection chamber 104, and driving the mold connecting plate 105 to perform adsorption detection. The detection chamber 104 is closed or opened. The adsorption detection chamber 104 uses the vacuum pump 113 to perform vacuum activation of the coating 102. Therefore, the coating 102 is fixedly placed inside the adsorption detection chamber 104, and then the coating material is placed on the coating 102. The start control component is activated to drive the mold connecting plate 105 to move downward. The mold connecting plate 105 drives the vacuum adsorption membrane 101 to move downward until it is in contact with the coating 102. The connecting plate 105 seals the upper end of the adsorption detection chamber 104, and then the vacuum pump 113 is started to create a vacuum environment inside the adsorption detection chamber 104, so that the coating material is vacuum adsorbed onto the coating part 102. After the vacuum adsorption is completed, the vacuum pump 113 is turned off and the vacuum pressure inside the adsorption detection chamber 104 is released. The mold connecting plate 105 is opened to drive the coating part 102, and whether bumps are formed on the coating part 102 is checked by a bump detection instrument, visual inspection, or touch.

[0036] The mounting plate 112 is fixedly connected to the support platform 103 and is located between two support plates at the bottom of the support platform 103; the vacuum pump 113 is fixedly connected to the mounting plate 112 and is located on top of the mounting plate 112; one end of the vacuum pipe 114 is fixedly connected to the suction end of the vacuum pump 113, and the other end of the vacuum pipe 114 is connected to the inner cavity of the adsorption detection chamber 104; the vacuum degree detector 115 is fixedly connected to the adsorption detection chamber 104 and is located on the inner side wall of the adsorption detection chamber 104. The mounting plate 112 provides a mounting pass condition for the vacuum pump 113 and increases the support stability of the support platform 103. When the vacuum pump 113 is started, the air in the adsorption detection chamber 104 is extracted through the vacuum pipe 114, creating a vacuum state in the inner cavity of the adsorption detection chamber 104. During the vacuum adsorption process, the vacuum adsorption membrane 101 helps the coating material to adhere tightly to the surface of the coating 102 under the action of vacuum force. The vacuum degree detector 115 is fixedly installed on the upper end of the left inner wall of the adsorption detection chamber 104 to monitor the vacuum degree in the adsorption detection chamber 104 in real time and transmit the data to the control system immediately, so that the operator can keep track of the vacuum status at any time. The vacuum adsorption membrane 101 is designed with concave dots to detect the adhesion of the coating material. The completion of the coating work can be determined by observing whether convex dots are formed at the concave dots.

[0037] Secondly, the sealing strip 106 is fixedly installed at the bottom of the mold connecting plate 105 and cooperates with the top of the adsorption detection chamber 104. The sealing strip 106 is made of rubber, and the bottom of the sealing strip 106 has a groove that matches the width of the top of the adsorption detection chamber 104. The sealing strip 106 increases the sealing performance of the mold connecting plate 105 to the adsorption detection chamber 104.

[0038] Meanwhile, the mounting frame 107 is fixedly connected to the support platform 103 by bolts and is erected in the middle position of the adsorption detection box 104; the pneumatic telescopic rod 108 is fixedly installed on the mounting frame 107, and the output end of the pneumatic telescopic rod 108 is fixedly connected to the mold connecting plate 105; the limiting rod 109 is fixedly connected to the mold connecting plate 105 and is located on both sides of the pneumatic telescopic rod 108; the mounting hole 110 is located in the middle of the top of the mounting frame 107 and penetrates the mounting frame 107; the limiting hole 111 penetrates both ends of the top of the mounting frame 107 and cooperates with the limiting rod 109. The mounting frame 107 has an inverted U-shaped structure, and the bottom support plate of the mounting frame 107 is fixedly installed by bolts. The pneumatic telescopic rod 108 is fixedly installed on the top of the mounting frame 107. The telescopic end of the pneumatic telescopic rod 108 passes through the mounting hole 110 and is fixedly connected to the top middle position of the mold connecting plate 105. The two ends of the top of the mold connecting plate 105 are symmetrically fixedly installed with the limiting rods 109. The two limiting rods 109 are respectively installed through the limiting hole 111. The limiting rods 109 limit the movement of the mold connecting plate 105. The pneumatic telescopic rod 108 drives the mold mounting plate 112 to move up or down, thereby realizing the up and down movement of the vacuum adsorption membrane 101, as well as the sealing and opening of the adsorption detection box 104.

[0039] Using the vacuum activation leak-proof detection method and apparatus for the coating 102 of the present invention, the coating 102 is fixedly placed inside the adsorption detection chamber 104, and then the coating material is placed on the coating 102. The start-up control component is activated to drive the mold connecting plate 105 to move downward. The mold connecting plate 105 drives the vacuum adsorption membrane 101 to move downward until it is in contact with the coating 102. The mold connecting plate 105 seals the upper end of the adsorption detection chamber 104. Then, the vacuum pump 113 component is activated to activate the adsorption detection chamber 104. A vacuum environment is formed inside the 04 chamber, and the coating material is vacuum adsorbed onto the coating part 102. After vacuum adsorption is completed, the vacuum pump 113 component is turned off, and the vacuum pressure inside the adsorption detection box 104 is released. The mold connecting plate 105 is opened to drive the coating part 102. The coating part 102 is checked for the formation of protrusions by a protrusion detection instrument, visual inspection, or touch to determine whether the coating process is completed. The vacuum adsorption process of the coating part 102 is realized by the vacuum activation device of the coating part, and it is convenient to determine whether the coating part 102 has undergone an empty adsorption process.

[0040] Second embodiment of this application:

[0041] Based on Example 1, see [link / reference] Figure 3 , Figure 3 This is a connection diagram of the vacuum activation device for the coating component according to the second embodiment of the present invention. The vacuum activation leak-proof detection assembly in this embodiment further includes a fixing component, which includes a clamping cylinder 216 and a pressing rubber plate 217.

[0042] The fixing components are located on the left and right sides of the adsorption detection chamber 104 and partially extend into the inner cavity of the adsorption detection chamber 104. The fixing components are installed at the middle positions of the left and right ends of the adsorption detection chamber 104, with both ends extending into the inner cavity of the adsorption detection chamber 104. The fixing components clamp and position the covering 102 placed in the adsorption detection chamber 104, ensuring that it will not move during the vacuum activation process.

[0043] Secondly, two clamping cylinders 216 are fixedly installed on the left and right sides of the outer side of the adsorption detection chamber 104, with the output ends of the clamping cylinders 216 extending into the adsorption detection chamber 104. The abutting rubber plate 217 is fixedly connected to the output ends of the clamping cylinders 216 and located within the adsorption detection chamber 104. The two clamping cylinders 216 are synchronously driven by an external control system to bring the two abutting rubber plates 217 closer together within the adsorption detection chamber 104, clamping and fixing the covering 102 placed within the adsorption detection chamber 104 to ensure it does not move during the detection process.

[0044] Please see Figure 4 The present invention also provides a method for detecting leaks during vacuum activation of a coating component, applied to the aforementioned vacuum activation device for the coating component, comprising the following steps:

[0045] S1: Add a recessed point to the vacuum adsorption membrane 101;

[0047] S3: Start the pneumatic control component to drive the mold connecting plate 105 to move downward, causing the vacuum adsorption membrane 101 to extend into the adsorption detection box 104 and seal the adsorption detection box 104.

[0049] S5: After vacuum adsorption is completed, turn off the vacuum pump component and release the vacuum pressure in the adsorption detection box 104, and take out the covering 102.

[0050] S6: Use a bump detection instrument, visual inspection, or touch to check whether bumps have been formed on the covering 102, thereby determining whether the covering process is complete.
