Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ceramic capacitor degassing production, and particularly relates to a heat conduction adjustable degassing box suitable for MLCC green body products and a heat conduction adjusting method thereof. BACKGROUND

[0002] Multi-layer Ceramic Capacitors (MLCC) are widely used in the fields of smart phones, digital cameras, automobiles, computers, 5G communication, etc. as a representative of passive components in the electronic component industry. In the industrial production of MLCC, there are many processes, including batching, casting, silk printing, layering, laminating, cutting, degassing, sintering, chamfering, end sealing, end burning, electroplating, testing, etc. The degassing process is crucial in the production of MLCC. Since the adhesive and plasticizer in the raw materials of MLCC production contain a certain proportion of high molecular organic matter, these organic matters will decompose and volatilize during the sintering process, resulting in product cracking and deformation and causing quality accidents. The purpose of degassing is to fully discharge the organic matter in the raw materials to ensure the sintering quality of the products. The effect of degassing is greatly affected by the degassing process and the uniformity of the temperature in the degassing box.

[0003] In the existing degassing method, the heat conduction method is to heat the air by the air blower of the degassing box, and then the heated gas is sent to the degassing box through the air supply pipe, and then the heated gas is sent to the degassing box through the heat conduction mesh plate on one side of the degassing box, and then the heated gas is sent to the degassing box through the air supply pipe. The MLCC green body products placed in the degassing box are heated and degassed, and the air containing glue is discharged from the mesh on the other side of the degassing box and the air exhaust pipe. The existing technology mainly has the following disadvantages:

[0004] (1) The heat conduction method of the current degassing box can cause a temperature difference of up to 7-10℃ at different positions in the degassing box, thereby causing local uneven heating of the products during the degassing process, and further affecting the sintering performance of the products;

[0005] (2) The positions and coverage of the heat conduction mesh plates on both sides of the degassing box are fixed, and the target area in the degassing box cannot be accurately heat conducted;

[0006] (3) The air inlet and outlet amounts during the heat conduction in the degassing box cannot be differentiated and adjusted according to the actual production needs.

[0007] Therefore, it is necessary to provide a heat conduction adjustable degassing box to improve the uniformity of the temperature in the degassing box, thereby solving the above problems. SUMMARY

[0019] Correspondingly, the application further provides a heat conduction adjustment method using the heat conduction adjustable degassing box. The box is provided with temperature detectors at different positions. The heat conduction adjustment method comprises the following steps:

[0051] The heat conduction adjustment method for the heat conduction adjustable degassing box 100 of the present application will be described below with reference to Figures 1-7 , which specifically comprises the following steps:

[0052] S01, sequentially loading the carrier plates 160 into the box body 110, and placing the products to be heated on the carrier plates 160;

[0053] S02, according to the area where the product is placed, rotate the roller 131 to drive the baffle 132 to move up and down, so that the baffle 132 covers the area of the mesh of the heat-conducting mesh unit 120 corresponding to the target area outside the product placement, then close the box door 111 of the box body 110 and set the temperature parameter;

[0054] S03, the gas conveying mechanism 140 conveys gas into the box body 110 through the gas inlet channel 110a and the heat-conducting mesh unit 120 connected thereto, the heating element heats the gas, and the hot gas flows in each layer of heating space to heat the product on the carrier plate 160, part of the hot gas is discharged to the gas outlet channel 110b through another heat-conducting mesh unit 120;

[0055] S04, after the glue removal is completed, record the actual temperature detected by each temperature detector;

[0056] S05, according to the actual temperature of each temperature detector, determine the area that needs to be adjusted in temperature, then repeat steps S02-S05 until the actual temperature error detected by each temperature detector reaches the set range.

[0057] When the actual temperature error detected by each temperature detector reaches the set range, the temperature adjustment step is completed, and the heat-conducting adjustable glue removal box 100 can be used for formal glue removal processing.

[0058] Next, combined with the above Figures 1-7 , the heat-conducting adjustable glue removal box 100 for the multi-layer ceramic capacitor (MLCC) is taken as an example, and the heat-conducting adjustment method and steps of using the heat-conducting adjustable glue removal box 100 are described.

[0059] S11, install each layer of carrier plate 160 in the box body 110. In an embodiment, four layers of carrier plates 160 are installed in the box body 110, and the four layers of carrier plates 160 divide the inside of the box body 110 into five layers of heating space, wherein the bottommost heating space is a gas heating space for heating gas by a heating element, and the heating spaces above the four layers of carrier plates 160 are product heating spaces.

[0060] S12, the MLCC green product transmitted from the cutting process is placed on a nickel mesh through a piece removal, and then the nickel mesh is placed on an alumina support, and then the support is laid on the carrier plate 160 in the box body 110, according to the number of products, the support with the green product is placed on the five layers of carrier plates 160.

[0061] Specifically, when the support is laid on the loading plate 160, according to the need of taking out the loading plate 160 from the box 110, the support will be kept a certain distance from the edge of the loading plate 160.

[0062] S13, adjust the heat-conducting mesh unit 120 and / or the movable baffle 130, and set the temperature parameters and the fan parameters required for heating.

[0063] Specifically, as shown in Figure 1 , Figure 4 When the heat-conducting mesh unit 120 has two heat-conducting mesh plates 121, 122, the two heat-conducting mesh plates 121, 122 are moved along the front-rear direction (Y direction) of the box 110, and the overlapping area of the two heat-conducting mesh plates 121, 122 is adjusted to achieve the purpose of mesh misalignment adjustment. If the heat-conducting mesh unit 120 has only one heat-conducting mesh plate, this adjustment step is omitted.

[0064] Next, as shown in Figures 5-7 According to the area where the products are placed, the roller 131 is manually rotated to move the baffle 132 up and down, so that the baffle 132 covers the target area outside the area where the green products are placed. The adjustment step of the baffle 132 is repeated to sequentially complete the adjustment of all movable baffles 130 in the four-layer product heating space.

[0065] Then, the box door 111 is closed, and the rotary handle knob is twisted to keep the inside of the box sealed. Then, the temperature parameters and the fan parameters required for heating are set through the display panel 112 on the front of the box 110.

[0066] S14, the air blower 142 is started to run by controlling the air blower switch, and the air blower 142 runs to send the gas into the air inlet duct of the air inlet pipe unit through the air inlet pipe 143, and then into the inside of the box 110 through the air inlet duct and the heat-conducting mesh unit 120; at the same time, the heating element heats the gas in the box 110, and part of the hot gas moves horizontally along the product heating space between the loading plates 160 to heat the green products on the loading plates 160.

[0067] More specifically, during the heating process, part of the hot gas is discharged through the heat-conducting mesh unit 120 on the other side of the exhaust box 110 to the air outlet duct of the air outlet pipe unit, and then discharged to the exhaust pipe 115 through the air outlet duct, and finally discharged to the outside of the box 110 through the exhaust pipe 115; at the same time, part of the hot gas enters the circulation pipe 150 through the bottom of the box 110, and is then sent to the air inlet duct again by the circulation pipe 150, and finally reenters the box 110 for recycling.

[0068] S15, the plurality of temperature detectors respectively monitor the temperature of different regions in the box 110 during the heating process, and the real-time temperature detected by the plurality of temperature detectors monitors the temperature of each region in the box 110. More specifically, the twelve temperature detectors in the box 110 respectively monitor the temperature of the four corner positions of the upper, middle and lower three layers in the box 110, and the temperature detected by the temperature detectors is displayed on the display panel 112, so that the temperature of each region in the box 110 can be monitored in real time.

[0069] S16, after the glue removal in the box is completed, the product is cooled to room temperature, then the movable baffle 130 is disassembled, and whether the side of the baffle 132 covering the heat-conducting mesh plate has dust or impurities is checked and cleaned in time.
