Description

Technical Field

[0001] This utility model relates to the field of ceramic packaging technology, specifically to a fixture for arranging low-temperature glass-ceramic cover plates. Background Technology

[0002] Ceramic packaging is a technology that uses low-melting-point glass as a sealing medium to encapsulate integrated circuit chips (ICs) or crystal oscillators. It is an ideal form of electronic packaging, with high hermeticity, good light shielding, high radiation resistance, low moisture content, and good mechanical, electrical, and chemical properties. Moreover, its packaging process is simple, low-cost, and highly reliable, making it suitable for large, medium, and small batch production. It has been widely used in military products, automobiles, and civilian high-reliability products.

[0003] When sealing low-temperature glass-ceramic covers and ceramic bases, the low-temperature glass-ceramic covers with the printed glass paste surface must be aligned in a regular, uniform manner. This ensures that the sealing of the ceramic covers and ceramic bases can be automated. Otherwise, manual alignment is extremely inefficient and can result in scratches and damage, leading to high operating costs. While automatic identification equipment exists, it is expensive and inefficient. Therefore, this invention proposes a fixture for arranging low-temperature glass-ceramic covers.

A vent hole is formed in the middle of the bottom inner wall of the sinks. A low-temperature glass-ceramic cover plate is provided on the inner wall of the sinks. The low-temperature glass-ceramic cover plate includes a ceramic layer at the bottom and a low-temperature glass slurry layer at the top. A lower clamping plate is fixedly connected to the bottom inner wall of the arranging plate layer. A venting block is fixedly inserted in the middle of the lower surface of the lower clamping plate.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a fixture for arranging low-temperature glass-ceramic cover plates, which has the following advantages:

[0015] This low-temperature glass-ceramic cover plate arrangement fixture, by setting a sink, vent, and air guide block, allows the device to be placed on an aligner. The low-temperature glass-ceramic cover plate is placed on the arrangement layer, and the air pump's suction pipe is inserted into the vent. When the aligner vibrates, the low-temperature glass-ceramic cover plate falls into the sink. When the ceramic layer is facing down, the low-temperature glass-ceramic cover plate is sucked into the sink. When the low-temperature glass paste layer is facing down, because the edge of the low-temperature glass paste layer is arc-shaped, it is easily thrown out of the sink and then re-enters the sink until all the low-temperature glass paste layers are facing up. This achieves automatic arrangement of the low-temperature glass-ceramic cover plates, greatly improving the efficiency of ceramic encapsulation and saving labor costs. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a fixture for arranging low-temperature glass-ceramic cover plates, including an arranging plate layer 1 and multiple sets of recesses 101 formed on the upper surface of the arranging plate layer 1. A vent hole 102 is formed in the middle of the bottom inner wall of the recesses 101. A low-temperature glass-ceramic cover plate 2 is provided on the inner wall of the recesses 101. The low-temperature glass-ceramic cover plate 2 includes a ceramic layer 201 at the bottom and a low-temperature glass slurry layer 202 at the top. A lower clamping plate 3 is fixedly connected to the bottom inner wall of the arranging plate layer 1. A venting block 4 is fixedly inserted in the middle of the lower surface of the lower clamping plate 3. Positioning posts 5 are inserted at the four corners of the upper surface of the arranging plate layer 1. A U-shaped positioning frame 7 is fixedly connected to the outer surface of the arranging plate layer 1. By setting the recesses 101, vent holes 102, and venting blocks 4, the fixture can achieve the desired effect. The device is placed on a sorting machine, model WH-4L-M. The low-temperature glass black ceramic cover plate 2 is placed on the sway layer 1. The air pump's suction pipe is inserted into the air guide hole 402. When the sorting machine vibrates, the low-temperature glass black ceramic cover plate 2 falls into the sink 101. When the ceramic layer 201 is facing down, the low-temperature glass black ceramic cover plate 2 is sucked into the sink 101. When the low-temperature glass paste layer 202 is facing down, because the edge of the low-temperature glass paste layer 202 is arc-shaped, it is easy to be thrown out of the sink 101 and then re-enter the sink 101 until all the low-temperature glass paste layers 202 are facing up. This realizes the automatic swaying arrangement of the low-temperature glass black ceramic cover plate 2, which greatly improves the working efficiency of ceramic encapsulation and saves labor costs.

[0024] In this invention, in order to achieve negative air pressure inside the settling tank 101, an air-guiding cavity 401 is provided inside the air-guiding block 4. Three sets of air-guiding holes 402 are opened on the left side of the outer surface of the air-guiding block 4, so that an air extraction pipe can be inserted into the air-guiding hole 402. The air extraction pipe can extract air from the swing plate layer 1 and the lower clamping plate 3 through the air-guiding cavity 401, thereby achieving negative air pressure inside the settling tank 101.

[0025] In this invention, in order to further enhance the stability of the connection between the swing plate layer 1 and the lower clamping plate 3, a gasket 6 is provided between the swing plate layer 1 and the lower clamping plate 3. The gasket 6 is made of silicone. By providing the gasket 6, the stability of the connection between the swing plate layer 1 and the lower clamping plate 3 is further enhanced.

[0026] In this invention, in order to make it easier for the low-temperature glass black ceramic cover plate 2, which faces downwards from the low-temperature glass slurry surface layer 202, to be thrown out of the sink 101, the depth of the sink 101 is 0.2 mm, the thickness of the ceramic layer 201 and the low-temperature glass slurry surface layer 202 are both 0.15 mm, and the number of sink 101 is 1225 sets. This makes the depth of the sink 101 slightly higher than the height of the low-temperature glass slurry surface layer 202, and the depth of the sink 101 lower than the total height of the low-temperature glass black ceramic cover plate 2, thereby making it easier for the low-temperature glass black ceramic cover plate 2, which faces downwards from the low-temperature glass slurry surface layer 202, to be thrown out of the sink 101.

[0027] In this invention, in order to reduce the probability that the corners of the ceramic layer 201 will be stuck in the sink 101, clearance holes 103 are provided at the four corners of the inner wall of the sink 101. The inner diameter of the clearance holes 103 is 0.5 mm. By setting the clearance holes 103, the probability that the corners of the ceramic layer 201 will be stuck in the sink 101 is further reduced.

[0028] In this invention, in order to further reduce the processing cost of the device, the materials of the swing plate layer 1, the lower clamping plate 3 and the air guide block 4 are all bakelite. By setting the materials of the device, the processing cost of the device is reduced and the structural stability of the device is ensured.

[0029] In use, insert the air extraction pipe from the air pump into the air guide hole 402, place the tooling such as the swaying layer 1 on the alignment machine, and secure the edge of the lower clamping plate 3 into the alignment box on the alignment machine. Place a large number of low-temperature glass black ceramic cover plates 2 above the swaying layer 1, start the alignment machine and air pump, and the air between the swaying layer 1 and the lower clamping plate 3 is extracted. The alignment machine drives the swaying layer 1 to swing up, down, left, and right and vibrate. The low-temperature glass black ceramic cover plates 2 may fall into the settling tank 101. When the ceramic layer 201 is facing down, because the edge of the ceramic layer 201 is at a right angle, the edge of the ceramic layer 201 fits tightly against the settling tank 101, so the low-temperature glass black ceramic cover plates 2... When the low-temperature glass slurry surface layer 202 is facing downwards, it is easily thrown out of the settling tank 101 because the edge of the low-temperature glass slurry surface layer 202 is arc-shaped and the edge of the low-temperature glass slurry surface layer 202 is loosely attached to the settling tank 101. Moreover, the middle of the low-temperature glass slurry surface layer 202 has a depression, which is not conducive to air pressure suction. It can then re-enter the settling tank 101. After about thirty seconds of vibration and swinging, all the low-temperature glass black ceramic cover plates 2 that have entered the swing plate layer 1 are in the state where the low-temperature glass slurry surface layer 202 is facing upwards. Then, the remaining low-temperature glass black ceramic cover plates 2 that have not entered the settling tank 101 are taken out, thus realizing the swinging operation of the low-temperature glass black ceramic cover plates 2.

[0030] In summary, this low-temperature glass-ceramic cover plate arrangement fixture, by setting a sink 101, a vent 102, and a vent block 4, allows the device to be placed on an aligner. The low-temperature glass-ceramic cover plate 2 is placed on the arrangement layer 1. The vent 402 is inserted into the suction pipe of an air pump. When the aligner vibrates, the low-temperature glass-ceramic cover plate 2 falls into the sink 101. When the ceramic layer 201 faces downward, the low-temperature glass-ceramic cover plate 2 is sucked into the sink 101. When the low-temperature glass paste layer 202 faces downward, because the edge of the low-temperature glass paste layer 202 is arc-shaped, it is easily thrown out of the sink 101 and then re-enters the sink 101 until all the low-temperature glass paste layers 202 face upward. This achieves automatic arrangement of the low-temperature glass-ceramic cover plate 2, greatly improving the efficiency of ceramic encapsulation and saving labor costs.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
