[0015] In the technical solution, the method of using the double-paddle disk capping device comprises the steps of: (1) The silver dipping horizontal movement arm module drives the silver dipping clamping air pressure carrier to enter above the silver dipping front tray through the left and right horizontal movement screw rods. The first servo motor descends to the silver dipping front tray to clamp the first thick silicone plate with the chip component. The first servo motor drives the silver dipping clamping air pressure carrier to rise to the highest point, moves horizontally to the right to above the temperature-sensing silver dipping paste disk and then descends. The temperature-sensing silver dipping paste disk moves back and forth through the slider and works by setting the silver dipping mode; (2) After the silver dipping work is completed, the silver dipping clamping air pressure carrier is raised to the highest position by the first servo motor, and the silver dipping horizontal movement arm module drives the silver dipping clamping air pressure carrier to move horizontally to the right above the vacuum degassing tray. The first servo motor descends to discharge the first thick silicone plate with the chip component onto the vacuum degassing tray; (3) The silver-dipping transverse arm module drives the silver-dipping clamping air pressure carrier to return to the top of the silver-dipping front tray (4) via the transverse screw rod, and repeats the operation of clamping the next second thick silicone plate with a sheet element; (4) When the silver dipping horizontal movement arm module starts to move, the smoothing horizontal movement arm module starts to drive the smoothing clamping air pressure carrier to enter the vacuum degassing tray. The second servo motor descends to the vacuum degassing tray to clamp the first thick silicone plate with the chip element, then rises to the highest position, moves horizontally to the right to the temperature-sensing smoothing slurry disk and then descends. The smoothing clamping air pressure carrier moves back and forth through the slider and works by setting the smoothing mode; (5) After the smoothing work is completed, the smoothing clamping air pressure carrier is raised to the highest position by the second servo motor, and the smoothing horizontal movement arm module drives the smoothing clamping air pressure carrier to move horizontally to the right above the discharge tray, and the second servo motor descends to discharge the first thick silicone plate with the chip component onto the discharge tray; (6). The leveling and traverse arm module drives the leveling and clamping air pressure carrier to return to the top of the vacuum degassing tray via the traverse screw rod, and repeats the operation of clamping the next plate of the second thick silicone plate with the sheet element.
[0016] Furthermore, steps (1) to (3) and steps (4) to (6) are all performed simultaneously and seamlessly through time setting, so that the silver dipping and smoothing processes can be performed at the same time.
[0017] In this technical solution, the main function of the silver dipping transverse shifting arm module is to link the silver dipping clamping air pressure carrier to clamp the first thick silicone plate from the silver dipping front tray. The silver dipping transverse shifting arm module works along the X-axis, and enters the temperature-sensing adjustment silver paste tray to dip the paste through the left and right transverse shifting screws. After completing the work, it moves transversely to the vacuum degassing tray.
[0018] The first gripper device and the second gripper device both use cylinder grippers with limit switches to reduce the probability of deformation of the first thick silicone plate and the second thick silicone plate; the first suction cup and the second suction cup ensure that the first thick silicone plate and the second thick silicone plate are respectively clamped by the first gripper device and the second gripper device. The overall plane is attached to the bottom of the first suction cup and the second suction cup, so that the silver-dipped chip capacitors are ensured to be stably silver-dipped on a horizontal plane; the entire silver-dipped clamping air pressure carrier is lifted up and down by the first servo motor to perform Z-axis work.
[0019] The temperature-sensitive adjustable silver paste dip tray has a constant temperature adjustment function, which is driven by a hot and cold water machine to adjust the temperature. This function can keep the slurry stable when it is spread on the temperature-sensitive adjustable silver paste dip tray. The bottom of the temperature-sensitive adjustable silver paste dip tray works along the first Y-axis track through the front and rear slide rails; it is normally and effectively adhered to the chip capacitor end according to the silver dipping method, and the slurry thickness can also be adjusted according to the user's parameters for the product's silver dipping process, in order to allow the chip capacitor end to be dipped around and on the top of the end.
[0020] The main function of the vacuum debubble tray is to remove the bubbles on the silver-stained end of the chip capacitor through vacuum. Multiple vacuum debubble removal and time settings can be set according to the process.

[0022] There are limit cylinder clamps on the front and back sides of the smoothing and clamping air pressure platform. The function of the limit cylinder clamps is to reduce the deformation probability of the thick silicone plate. A stainless steel second suction cup is installed under the platform. The function of the second suction cup is to ensure that the overall plane of the thick silicone plate fits under the suction cup after the cylinder clamps are clamped, so that the silver-coated chip capacitors can be smoothed on a horizontal plane. The entire smoothing and clamping air pressure platform is lifted up and down by the second servo motor to perform Z-axis work. The temperature-sensing adjustment and leveling slurry plate also has a constant temperature adjustment function. The temperature is adjusted by the hot and cold water machine. The bottom of the slurry plate works on the Y axis through the front and rear slide rails. The temperature-sensing adjustment and leveling slurry plate is used to level the slurry at the top of the chip capacitor after the first silver dip, so that the overall thickness of the chip capacitor remains consistent after silver dip. The purpose is to ensure that the slurry adsorbed inside and outside the chip capacitor end after silver dip can be dried quickly after drying, so as to protect the chip capacitor. The discharge tray discharges the smoothed thick silicone sheet onto this tray in preparation for the next job.
[0023] The double-slurry disk sealing device of the present invention has double silver disks, double slurry dipping platforms, and double slurry spreading scraper mechanisms. The double slurry dipping platforms have the function of end smoothing linked by three axes of X, Y, and Z, and can realize the end leveling function by means of forward and backward movement, polygonal movement, spiral movement, etc.; it has the function of CCD detection of scratch defects on the silver layer on the slurry surface after the scraper spreads the slurry, so as to ensure the quality of each scraper spreading the slurry; it has the function of automatic slurry addition and slurry position detection and control to prevent the slurry box from lacking slurry and adding too much slurry; the slurry dipping process has the function of CCD slurry dipping high-definition video visualization, so that the entire slurry spreading action process can be visualized and supports the video playback function; the end slurry dipping can set 6 different slurry dipping process parameters, and the slurry dipping position, slurry spreading stop position, and slurry spreading thickness of each stage can be set; the slurry disk has a constant temperature adjustment function and is equipped with a hot and cold water machine; it has vacuum degassing after sealing Function, you can choose to set multiple-stage immersion and multiple vacuum defoaming functions, and the vacuuming time can be set according to the requirements. After the above functions are set in response to the end sealing requirements, the silver-dipping horizontal moving arm module rises to the highest position after the board storage rack sucks the board, moves horizontally to the top of the temperature-sensing adjusted silver-dipping paste disk, and descends to a certain height for flat dipping. After completion, the silver-dipping horizontal moving arm module discharges the board to the temporary storage tray for vacuum suction, and then returns to the storage rack to take the board for the next board operation. At the same time, the leveling horizontal moving arm module sucks the sealed end board that has completed vacuum suction on the temporary storage tray, rises to the highest position, and then moves horizontally to the top of the temperature-sensing adjusted leveling paste disk, and descends to a certain height for air immersion. After completion, the leveling horizontal moving arm module discharges the board to the discharge storage rack, and then the leveling horizontal moving arm module returns to the temporary storage tray to suck the board for the next board operation.
