Description

Technical Field

[0001] This utility model belongs to the field of glass product processing technology, specifically relating to a glass powder encapsulation and rapid cooling and shaping device. Background Technology

[0002] In the production of electronic components and optical devices, glass powder encapsulation is widely used due to its advantages such as excellent sealing, high temperature resistance, and strong insulation. After glass powder encapsulation is completed, it needs to undergo a cooling and shaping process to solidify the molten glass powder and maintain a stable shape. The cooling rate, uniformity, and stress control in this process directly affect the dimensional accuracy, mechanical properties, and service life of the encapsulated parts.

[0003] Traditional cooling and shaping devices use a single cooling process, where high-temperature encapsulated parts directly contact a low-temperature environment, which can easily generate huge internal stress and lead to a high cracking rate. Although some devices use zoned cooling, the airflow in the two zones interferes with each other, making it impossible to form a stable temperature gradient and resulting in poor cooling uniformity. The special fixtures of traditional cooling and shaping devices can only be adapted to a single specification of encapsulated parts. When changing products, the fixtures need to be customized again, which cannot meet the needs of multi-variety, small-batch production. Therefore, a rapid cooling and shaping device for glass powder encapsulation has emerged. Utility Model Content

[0025] Example

[0026] Reference Figures 1-4 This embodiment of the present invention provides a glass powder encapsulation rapid cooling and shaping device, comprising:

[0027] The transmission mechanism 100 includes a support leg 101, a worktable 102 fixedly installed on the top of the support leg 101, a motor 103 adapted to be installed on the side wall of the worktable 102, a roller 104 sleeved on the output end of the motor 103 and rotating in the T-slot of the worktable 102, a conveyor belt 105 sleeved on the outer circumferential surface of the roller 104, and a clamping assembly 106 movably installed on the surface of the conveyor belt 105.

[0028] Cooling mechanism 200 includes a cooling cover 201 fixedly installed on the surface of workbench 102, a partition plate 202 fixedly installed on the surface of workbench 102 with its top connected to the center of the inner wall of the cooling cover 201, a slow-cooling zone chiller 203 disposed on the side of the support leg 101, a slow-cooling zone cooling pipe 204 movably installed on the inner wall of the cooling cover 201, a slow-cooling zone fan 205 movably installed in the circular mounting hole at the top of the cooling cover 201, and a slow-cooling... The system includes a slow-cooling zone mounting bracket 206, a slow-cooling zone air guide hood 207 fixedly installed at the bottom of the slow-cooling zone mounting bracket 206, a fast-cooling zone chiller 208 located on the side of the support leg 101, a fast-cooling zone cooling pipe 209 movably installed on the inner wall of the cooling cover 201, a fast-cooling zone fan 210 movably installed in the circular mounting hole at the top of the cooling cover 201, a fast-cooling zone mounting bracket 211 fixedly installed on the top wall of the inner cavity of the cooling cover 201, and a fast-cooling zone air guide hood 212 fixedly installed at the bottom of the slow-cooling zone mounting bracket 206.

[0029] In the cooling mechanism 200, the cooling cover 201 is made of stainless steel, and the partition plate 202 is also made of stainless steel. Both are fixedly installed on the surface of the workbench 102, with their tops welded to the center of the inner wall of the cooling cover 201, dividing the interior of the cooling cover into two zones. The slow-cooling zone chiller 203 is located on the side of the support leg 101, with a cooling capacity of 5kW. The slow-cooling zone cooling pipe 204 is made of copper and is movably installed on the inner wall of the cooling cover 201 via pipe clamps, connected to the slow-cooling zone chiller 203 via a pipe. The slow-cooling zone fan 205 has a power of 1.5kW and is movably installed in the circular mounting hole at the top of the cooling cover 201. The slow-cooling zone mounting bracket 206 is a welded angle steel structure, fixedly installed on the inner wall of the cooling cover 201, with the slow-cooling zone air guide shroud 207 fixedly installed at its bottom. The rapid-cooling zone chiller 208 has a cooling capacity of 10kW and is located on the other side of the support leg 101. The cooling pipe 209 in the rapid cooling zone has the same specifications as the cooling pipe 204 in the slow cooling zone. It is movably installed on the inner wall of the other side of the cooling cover 201 and connected to the chiller 208 in the rapid cooling zone. The fan 210 in the rapid cooling zone has a power of 2.2kW and is movably installed in another circular mounting hole on the top of the cooling cover 201. The mounting bracket 211 in the rapid cooling zone has the same structure as the mounting bracket 206 in the slow cooling zone and is fixed to the top wall of the inner cavity of the cooling cover 201. The air guide shroud 212 in the rapid cooling zone is fixedly installed at the bottom of the mounting bracket 206 in the slow cooling zone.

[0030] Specifically, the air guide plate inside the slow cooling zone air guide hood 207 is inclined at a 45° angle to the horizontal plane, and air vents are evenly opened on the plate.

[0031] Furthermore, the air guide plate inside the slow cooling zone air guide shroud 207 is made of aluminum alloy plate and is inclined at a 45° angle to the horizontal plane. This guides the airflow blown by the slow cooling zone fan 205 to the encapsulation components on the surface of the conveyor belt 105. Ventilation holes are evenly distributed on the air guide plate, allowing some airflow to disperse and flow out through the holes, forming a gentler airflow suitable for the cooling needs of the slow cooling zone and preventing internal stress from the encapsulation components caused by rapid cooling.

[0032] Preferably, the air guide plate inside the quick-cooling zone air guide shroud 212 is inclined at a 60° angle to the horizontal plane, and the plate has evenly spaced ventilation holes.

[0033] It should be noted that the air guide plate inside the rapid cooling zone air guide shroud 212 is also made of aluminum alloy plate and is inclined at a 60° angle to the horizontal plane. Compared with the air guide plate in the slow cooling zone, the angle is larger, which can more concentratedly guide the airflow blown out by the rapid cooling zone fan 210 to the encapsulation component and enhance the cooling intensity.

[0034] When in use, turn on the slow cooling zone chiller 203 and the rapid cooling zone chiller 208, preset the water temperature of the slow cooling zone cooling pipe 204 to 40-50℃, and the water temperature of the rapid cooling zone cooling pipe 209 to 5-15℃; adjust the speed of the slow cooling zone fan 205 to 800-1200r / min, and the speed of the rapid cooling zone fan 210 to 2500-3000r / min, start the motor 103, and the packaged part enters the slow cooling zone of the cooling cover 201 first with the conveyor belt. The warm water in the slow cooling zone cooling pipe 204 dissipates heat slowly through the pipe wall. At the same time, the airflow generated by the slow cooling zone fan 205 is guided by the 45° inclined air guide plate, and combined with the vent holes to form a dispersed and gentle airflow, so that the temperature of the packaged part drops from 300-400℃ to 150-200℃ within 3-5 minutes, initially reducing the temperature to avoid excessive stress during subsequent rapid cooling. During this process, the rectangular notch at the lower end of the partition plate 202 provides passage space for the conveyor belt, and the airflow channel hole at the upper end balances the air pressure in the two zones to prevent airflow turbulence. The packaged component passes through the notch of the partition plate 202 and enters the rapid cooling zone. The low-temperature cold water in the cooling pipe 209 of the rapid cooling zone quickly absorbs heat. The high-speed airflow generated by the fan 210 in the rapid cooling zone is guided by the air guide plate at a 60° angle. Since the air guide shroud has no vent holes, the airflow is concentrated and blown onto the surface of the packaged component, quickly carrying away heat and reducing the temperature from 150-200℃ to 40-60℃ within 1-2 minutes, thus achieving rapid curing and shaping of the glass powder.

[0035] In summary, a stepped cooling process from a slow cooling zone to a rapid cooling zone is adopted. First, the packaged parts are cooled smoothly from 300-400℃ to 150-200℃ using warm water at 40-50℃ and gentle airflow in the slow cooling zone, avoiding excessive internal stress caused by direct rapid cooling. Then, the packaged parts are cooled rapidly to 40-60℃ using low-temperature cold water at 5-15℃ and concentrated airflow in the rapid cooling zone, achieving solidification and shaping. This ensures cooling efficiency and reduces the risk of cracking and deformation of the packaged parts. The vent design of the air guide hood 207 in the slow cooling zone and the ventless design in the rapid cooling zone create a differentiated airflow distribution, which is adapted to the needs of gentle cooling and rapid shaping, respectively, so that packaged parts of different sizes and shapes can dissipate heat evenly. The spacing of the jaws 206f of the clamping component 106 can be adjusted by the lead screw 106c. Combined with the buffering effect of the preload spring 206g, it can stably clamp regular shaped products and also accommodate irregularly shaped packaged parts with slight protrusions.
