Description

Technical Field

[0001] This invention relates to the field of ceramic packaging shell production technology, specifically a pretreatment process for gold plating on the surface of military ceramic packaging components. Background Technology

[0002] Electronic ceramic housings can achieve high airtightness and high reliability in tiny spaces, thus contributing to the miniaturization of end products. With the development of emerging fields such as smart cars, the Internet of Things, and drones, the application areas of electronic ceramic housings are constantly expanding.

[0003] A Chinese invention application with publication number CN116207059A discloses a partially gold-plated ceramic encapsulation shell and a production device for the encapsulation shell. The device includes a support frame a, a support frame b, a motor, and a turntable that moves in a circular motion driven by the motor. The turntable has several placement slots for placing ceramic encapsulation shells. A power component is provided at the upper end of the support frame b. The power component is equipped with an air blowing mechanism and an adhesive application mechanism. The adhesive application mechanism applies adhesive to the ceramic encapsulation shell through the air blowing action of the air blowing mechanism.

[0004] However, the inventors discovered that the adhesive in the aforementioned comparative documents was blown into the ceramic packaging shell through an air tube. The air blowing method could not evenly spread the adhesive on the components, and the conductive parts on the components could not be prevented from being contaminated with adhesive. Based on this, a pretreatment process for gold plating on the surface of military ceramic packaging components was proposed. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by setting a sealing chamber at the upper end of the component, with a sealing component slidably disposed inside the sealing chamber. The sealing chamber seals the component via a lifting component. An inflation component is located on one side of the sealing chamber to fill the gap between the silicone plate and the component, preventing adhesive from flowing into the conductive area. A worktable is located on one side of the turntable, with an adhesive injection component on the worktable. A balancing component is located on one side of the adhesive injection component, and a pressing component is located on the other side of the balancing component to pressurize the adhesive. When the adhesive injection component injects and extracts adhesive from the component, the balancing component maintains the air pressure balance inside the sealing chamber. During the pressurization process, the pressurizing component simultaneously drives the balancing component to seal the inside of the sealing chamber before pressurizing, resulting in better adhesion of the adhesive to the component.

[0006] To address the aforementioned technical problems, the present invention adopts the following technical solution:

[0010] Step 3, glue injection process: The first cylinder pushes the fixed plate down, so that the glue injection cylinder and the air pressure chamber are inserted under the pressure plate. The second cylinder pushes the piston rod b to inject the glue onto the component.

[0011] Step four, pressurization process: the third cylinder drives the piston rod c to move down synchronously with the pressure plate to pressurize the upper surface of the component.

[0017] As a preferred embodiment, in step four, a spring is provided between the silicone plate and the pressure plate. The third cylinder presses down, causing the piston rod c to move to the bottom of the hollow groove, sealing the inside of the sealing chamber. During the continuous pressing of the piston rod c, the air pressure chamber and the pressure plate synchronously apply pressure to the adhesive.

[0018] As another preferred embodiment, in step five, the piston rod c is located at the upper end of the hollow groove, and the air pressure inside the sealed chamber remains balanced.

[0019] This invention also provides a pretreatment device for gold plating of military ceramic packaged components, which is compatible with a pretreatment process for gold plating of military ceramic packaged components.

[0052] Step four, pressurization process: the third cylinder 111 drives the piston rod c104 and the pressure plate 52 to move down synchronously to pressurize the upper surface of component 3.

[0053] Step 5, glue extraction process: The output shaft of the second cylinder 95 retracts to extract the excess glue from the upper surface of component 3, and the output shaft of the first cylinder 92 retracts to reset the fixing plate 91.

[0054] like Figures 3 to 5 As shown, in step one, a support rod 61 is provided on one side of the sealing chamber 4. When the support rod 61 slides on the rising section 632 of the guide rail a63, the bearing frame 12 and the component 3 do not contact each other.

[0055] like Figures 3 to 5 As shown, in step two, the support rod 61 on one side of the sealing chamber 4 slides on the guide rail a63, and under the action of the baffle 633, the sealing chamber 4 abuts against the component 3.

[0056] like Figures 3 to 4 As shown, in step two, the piston rod a74 is pushed to move in the air chamber 73 by the guide rail b75, and the gas flows from the air pipe 72 to the air bag 71, causing the air bag 71 to expand at the junction of the pressure plate 52 and the component 3.

[0057] like Figures 6 to 9 As shown, in step three, by providing a one-way valve 97 at the lower end of the material cylinder 96, when the second cylinder 95 drives the piston rod b94 to reset, the material cylinder 96 automatically replenishes adhesive into the glue injection cylinder 93.

[0058] like Figures 7 to 10 As shown, in step four, a spring is provided between the silicone plate 51 and the pressure plate 52. The third cylinder 111 presses down to drive the piston rod c104 to move below the hollow groove 103, and the sealing chamber 4 is sealed inside. During the continuous pressing of the piston rod c104, the air pressure chamber 102 and the pressure plate 52 simultaneously apply pressure to the adhesive.

[0060] Example 2

[0061] like Figures 1 to 10As shown, a pretreatment device for gold plating of military ceramic encapsulated components includes a support frame 1 and a turntable 2 rotatably mounted on the support frame 1. The upper surface of the turntable 2 has a support platform 12 for placing components 3 along the circumferential direction. A sealing chamber 4 is provided at the upper end of the component 3. A sealing component 5 is slidably arranged inside the sealing chamber 4. The sealing chamber 4 seals the component 3 through a lifting component 6. An inflation component 7 is provided on one side of the sealing chamber 4. A worktable 8 is provided on one side of the turntable 2. An adhesive injection component 9 is provided on the worktable 8. A balancing component 10 is provided on one side of the adhesive injection component 9. An extrusion component 11 for pressurizing the adhesive is provided on one side of the balancing component 10. When the adhesive injection component 9 injects and extracts adhesive from the component 3, the balancing component 10 maintains the air pressure balance inside the sealing chamber 4.

[0062] It is worth mentioning that a motor is installed at the lower end of the turntable 2, and the motor drives the turntable 2 to rotate through the action of the belt and pulley.

[0063] like Figures 3 to 4 As shown, the sealing assembly 5 includes a silicone plate 51 slidably disposed within the sealing chamber 4 and a pressure plate 52 disposed on the silicone plate 51.

[0064] In this embodiment, the silicone plate 51 is made of silicone, which has a small amount of elasticity, making it easy to apply pressure to the silicone plate 51 later.

[0065] like Figures 3 to 5 As shown, the lifting assembly 6 includes a support rod 61 disposed on one side of the sealed chamber 4, a fixed column 62 disposed on the support rod 61, a guide rail a63 disposed above the turntable 2, and a sliding groove 64 disposed within the guide rail a63.

[0066] It is worth mentioning that during the rotation of the sealing chamber 4, it is raised and lowered under the action of the guide rail a63. During the parallel section 632, the baffle 633 can hold the sealing chamber 4 in place to prevent air leakage due to pressure imbalance during the later pressurization process.

[0067] like Figure 4 As shown, the inflation assembly 7 includes an airbag 71 disposed at the junction of the silicone plate 51 and the component 3, an air pipe 72 communicating with the airbag 71 and disposed on the sealed chamber 3, an air chamber 73 disposed at the other end of the air pipe 72, a piston rod a74 slidably disposed in the air chamber 73, and a guide rail b75 disposed in the middle of the turntable 2 and controlling the position of the piston rod a74.

[0068] In this embodiment, the inflation component 7 can fill the gap between the silicone plate 51 and the component 3, preventing the adhesive from flowing into the conductive area and avoiding the problem of adhesive being difficult to remove from the conductive area of ​​the component 3.

[0069] like Figure 5 As shown, a groove 751 is provided in the middle of the guide rail b75, and the height of the groove 751 is greater than the lifting range of the sealing chamber 4.

[0070] It is worth mentioning that the inflation component 7 is installed on the sealed chamber 3. When the lifting component 6 drives the sealed chamber 3 to rise and fall, the piston rod a74 on the inflation component 7 slides continuously in the groove 751 of the guide rail b75.

[0071] like Figures 6 to 10 As shown, the glue injection assembly 9 includes a fixed plate 91 slidably disposed on the worktable 8, a first cylinder 92 fixedly disposed on the worktable 8, a glue injection cylinder 93 disposed on the lower end face of the fixed plate 91, a piston rod b94 slidably disposed inside the glue injection cylinder 93, a second cylinder 95 disposed above the fixed plate 91 and connected to the piston rod b94, a material cylinder 96 disposed on one side of the glue injection cylinder 93, and a one-way valve 97 disposed between the material cylinder 96 and the glue injection cylinder 93.

[0072] In this embodiment, the first cylinder 92 pushes the components on the fixed plate 91 to move down synchronously, and the second cylinder 95 pushes the piston rod b94 to inject and extract glue. During the glue extraction process, the glue injection cylinder 93 automatically replenishes glue into the glue injection cylinder 93.

[0073] like Figures 6 to 10 As shown, the balancing assembly 10 includes a limiting plate 101 disposed on one side of the dispensing cylinder 93, a pressure chamber 102 disposed at the lower end of the limiting plate 101, a hollow groove 103 disposed at the upper end of the pressure chamber 102, a piston rod c104 slidably disposed in the pressure chamber 102, and a movable sleeve 105 fixedly disposed below the limiting plate 101; the movable sleeve 105 is provided with a limiting groove 106 inside, and the piston rod c104 is slidably disposed in the limiting groove 106.

[0074] It is worth mentioning that during the glue injection and extraction process, the piston rod c104 is located at the upper end of the hollow groove 103 to maintain the air pressure balance inside the sealed chamber 4.

[0075] like Figures 6 to 10 As shown, the extrusion assembly 11 includes a third cylinder 111 disposed below the fixed plate 91 and a connecting rod 112 disposed between the third cylinder 111 and the piston rod c104.

[0076] In this embodiment, a spring is also provided between the silicone plate 51 and the pressure plate 52. During the process of the third cylinder 111 pressing down, the piston rod c104 is first driven to move down, so that the inside of the sealing chamber 4 is sealed. When the third cylinder 111 continues to press down, the air pressure chamber 102 and the pressure plate 52 simultaneously apply pressure to the inside of the sealing chamber 4, driving the adhesive to better bond with the component 3.

[0077] The work process is as follows:

[0078] The component 3 is placed manually in the support frame 12. When the turntable 2 rotates, the guide rail a63 drives the sealing chamber 4 to fit against the frame of the component 3. The guide rail b75 drives the piston rod a74 to move towards the inside of the air chamber 73, causing the air pipe 72 to expand.

[0079] When component 3 is rotated to the bottom of workbench 8, the first cylinder 92 pushes the fixing plate 91 down, so that the glue injection cylinder 93 and the air pressure chamber 102 are inserted under the pressure plate 52. The second cylinder 95 pushes the piston rod b94 to inject glue onto component 3. The third cylinder 111 drives the piston rod c104 and the pressure plate 52 to move down synchronously to pressurize the upper surface of component 3. After the output shaft of the third cylinder 111 retracts, the output shaft of the second cylinder 95 retracts to remove excess glue from the upper surface of component 3. The output shaft of the first cylinder 92 retracts, driving the fixing plate 91 to reset.
