Description

Technical Field

[0001] This invention relates to the field of resonator manufacturing equipment, and more particularly to a quartz crystal resonator wafer arrangement and cleaning device. Background Technology

[0002] A quartz crystal resonator is an electronic device that achieves stable frequency output based on piezoelectric characteristics. It typically consists of a quartz chip, a support base, a sealed shell, and conductive adhesive. It plays a role in frequency control and selection in various oscillation and filtering circuits and is widely used in communication devices, audio-visual products, timing instruments, information terminals, and everyday electronic products.

[0003] The core of a quartz crystal resonator is the quartz crystal wafer. Its production process mainly involves cutting the quartz into appropriate sizes and then plating silver onto both sides of the crystal as electrodes. The uniformity of the plating directly affects the resonator's performance. Therefore, before plating the quartz crystal wafer, it is necessary to thoroughly clean it to remove impurities such as grease and particles from its surface. An existing patent (CN210586174U) describes a resonator wafer cleaning device that mentions achieving thorough cleaning of the quartz crystal wafer through a multi-stage cleaning method. However, it does not consider the limitations of ultrasonic cleaning in handling adhering substances on the quartz crystal wafer. Furthermore, in existing ultrasonic cleaning technology, the cleaning fluid and impurities are difficult to separate effectively, easily causing secondary contamination. The cleaning process is not smoothly connected, leading to cross-contamination between tanks, low cleaning efficiency, and the inability to simultaneously perform thorough, dead-angle-free cleaning of both the wafer and the supporting device, requiring additional cleaning steps.

This achieves integrated cleaning and drying operations, effectively avoiding the need to transfer the wafers to the drying equipment for further drying after drying, which can easily lead to wafer contamination during the transfer process and affect the wafer processing effect and efficiency.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0021] A quartz crystal resonator wafer arrangement and cleaning device, according to Figures 1-8 As shown, it includes a shock absorber base 1 and a movement control unit; the movement control unit is connected to the shock absorber base 1.

[0022] The mobile control unit includes an electric push rod 2, an annular electric guide rail 3, an electric slider 4, and an electric clamp 5; two electric push rods 2 are installed on the left and right sides of the shock absorber 1, distributed front and back; the telescopic parts of all the electric push rods 2 are fixedly connected to the annular electric guide rail 3; several electric sliders 4 are slidably connected on the annular electric guide rail 3; each electric slider 4 is fixedly connected to an electric clamp 5; each electric clamp 5 corresponds to a cleaning basket 6.

[0023] It also includes a slider 7, a limiting rope 8, a spring 9, and a magnetic piece 10; the cleaning basket 6 has several limiting grooves 601; four rectangular sliders 7 are slidably connected to the cleaning basket 6; several limiting ropes 8 are connected between each slider 7 and non-adjacent sliders 7; all the limiting ropes 8 form a grid, and each intersection of the grid corresponds to a limiting groove 601; a silicone anti-slip pad is provided on the side of the cleaning basket 6 away from the limiting ropes 8; a spring 9 is fixedly connected to each slider 7; all springs 9 are fixedly connected to the cleaning basket 6; a magnetic piece 10 is fixedly connected to the side of each slider 7 away from the spring 9; several iron pieces are provided on the cleaning basket 6; each iron piece corresponds to a magnetic piece 10.

[0024] Each limiting groove 601 has a barrier net on the side away from the limiting rope 8, which is used to limit the wafer and facilitate the cleaning of the wafer.

[0025] The height of the first partition 12 on the right side gradually increases from front to back.

[0026] The height of the first partition 12 on the left gradually decreases from front to back.

[0027] It also includes a second partition 17, an air pump 18, a first conduit 19, and a second conduit 20; the multi-stage cleaning tank 11 is fixedly connected to the front of the second partition 17; the second partition 17 divides the space formed by the front of the multi-stage cleaning tank 11 and the shock absorber 1 into two sealed air chambers 1107; the right air chamber 1107 is equipped with an air pump 18; the exhaust port of the air pump 18 is connected to the left air chamber 1107; the suction port of the air pump 18 is connected to the right air chamber 1107; two sets of first conduits 19 are installed in the dust removal tank 1106, each set containing There are several vertically distributed first conduits 19; the right air chamber 1107 is connected to all the first conduits 19; the drying tank 1104 is equipped with two sets of second conduits 20, each set containing several vertically distributed second conduits 20; the left air chamber 1107 is connected to all the second conduits 20; each first conduit 19 and each second conduit 20 is provided with several air holes, each air hole is provided with a filter screen, and each air hole corresponds to a limiting groove 601; each second conduit 20 is provided with a heater.

[0028] First, the cleaning basket 6 is placed horizontally, with its silicone anti-slip pad in contact with the workbench surface to ensure stability. Then, the operator moves each slider 7, causing the magnetic piece 10 on the slider 7 to adhere to the iron plate of the cleaning basket 6. The spring 9 is stretched and deformed, causing the intersection of the limiting ropes 8 to move away from the position of the limiting groove 601. At this time, the external robotic arm can place the wafers into the limiting grooves 601 one by one. The wafers are placed on the net of the limiting grooves 601. Then, the operator moves each slider 7, causing the magnetic piece 10 to separate from the iron plate. The spring 9 returns to its original position, simultaneously driving the slider 7 to reset, so that the intersection of the limiting ropes 8 is back in the position of the limiting grooves 601. At this time, the wafers are located between the grid formed by the limiting ropes 8 and the net. When it is necessary to remove the wafers later, simply control the movement of the slider 7 to remove the limiting of the wafers. Combined with the automated loading and unloading of the production line, this achieves rapid loading and unloading of wafers, effectively improving the efficiency of wafer cleaning.

[0029] Then, the cleaning basket 6 is erected and moved to the position of the material table 1105. The cleaning basket 6 is clamped and fixed by the electric clamp 5. The electric slider 4 drives the electric clamp 5 and the cleaning basket 6 on it to move on the annular electric guide rail 3. When the cleaning basket 6 reaches the position of the side baffle of the bottom material table 1105, all the electric push rods 2 are controlled to extend, so that the cleaning basket 6 moves upward. After the cleaning basket 6 is higher than the multi-stage cleaning tank 11, the electric slider 4 continues to move, so that the cleaning basket 6 reaches the top of the dust removal tank 1106. Then, all the electric push rods 2 are controlled to retract, so that the cleaning basket 6 enters the dust removal tank 1106. The air pump 18 is started. The air pump 18 draws air from the dust removal tank 1106 through the first conduit 19 to pre-treat the wafers in the cleaning basket 6, reduce the amount of dust and impurities brought into the cleaning liquid tank 1101, and increase the frequency of subsequent cleaning of the cleaning liquid tank 1101.

[0030] Next, the electric push rod 2 is extended again, causing the cleaning basket 6 to move above the first cleaning fluid tank 1101. The cleaning basket 6 is then lowered into the cleaning fluid tank 1101, and the ultrasonic transducer on the first partition 12 is activated to perform ultrasonic cleaning on the wafers in the cleaning basket 6 in conjunction with the cleaning fluid. Since the cleaning basket 6 is placed vertically, the wafers are also in a vertical position. The mesh and the cross-shaped limiting ropes 8 on the cleaning basket 6 can limit the wafers, and the large gaps in the mesh and the cross-shaped limiting ropes 8 allow the cleaning fluid to pass through. Entering the limiting groove 601, the cleaning fluid fully contacts the wafer, thereby achieving simultaneous cleaning of the wafer on both sides. Compared with the existing technology of clamping and fixing the wafer for cleaning, this effectively reduces cleaning dead zones. Moreover, compared with the existing technology of scattering a large number of wafers in the cleaning carrier for simultaneous cleaning, it effectively avoids the problem of wafers scratching each other, resulting in wafer scratches and a high defect rate. Several first partitions 12 are set on the right side of the multi-stage cleaning tank 11, dividing the right side of the multi-stage cleaning tank 11 into multiple... The cleaning basket 6 is then removed from the front cleaning fluid tank 1101 and moved backwards. A pump 14 is installed next to the cleaning fluid tank 1101. The inlet of the pump 14 is connected to the front of the cleaning fluid tank 1101, and the outlet of the pump 14 is connected to the rear of the cleaning fluid tank 1101. This allows the cleaning fluid to circulate within the cleaning fluid tank 1101. Viewed from above, the cleaning fluid flows clockwise. The height of the first partition 12 gradually increases from front to back. Therefore, when cleaning the basket... During the cleaning of the wafers in cleaning basket 6, if the dust and impurities washed off from the wafers in cleaning basket 6 are intercepted in the cleaning liquid tank 1101 during the flow process, the cleaning liquid can pass over the first partition 12 and continue to flow forward. Since cleaning basket 6 moves counterclockwise, the cleaning liquid tank 1101 at the front has the most impurities washed off, and the impurities in the cleaning liquid decrease as it moves further back. As cleaning basket 6 moves, the wafers in cleaning basket 6 can be ultrasonically cleaned step by step, gradually improving the cleanliness of the wafers and effectively improving the quality of wafer cleaning.

[0031] Considering that cleaning solution residue remains on the wafer or cleaning basket 6 after wafer cleaning, subsequent rinsing with clean water is necessary. Therefore, several clean water tanks 1103 are set on the left side of the multi-stage cleaning tank 11 to clean the residual cleaning solution on the wafer and cleaning basket 6. The cleaning basket 6 is then moved further and transferred to the partition tank 1102. After the cleaning basket 6 enters the partition tank 1102, it moves within the partition tank 1102, during which most of the cleaning solution is drained. Then, the cleaning basket 6 is transferred to the last clean water tank 1103. At this point, the ultrasonic transducer on the first partition 12 is activated again, and the cleaning basket 6 and wafer are ultrasonically cleaned again, achieving further cleaning of the cleaning basket 6 and wafer, further reducing impurities and cleaning solution residue on the cleaning basket 6 and wafer. Then, the cleaning basket 6 is controlled to continue moving forward, so that the cleaning basket 6 enters each clean water tank 1103 in sequence. In actual use, the number of first partitions 12 can be adjusted according to the viscosity of the cleaning solution and the specifications of the wafers to achieve optimal cleaning efficiency. A pump 14 is also installed next to the clean water tank 1103. The inlet of the pump 14 is connected to the rear of the clean water tank 1103, and the outlet of the pump 14 is connected to the front of the clean water tank 1103, thus realizing the circulation of clean water. Looking from top to bottom, the clean water flows clockwise, while the height of the first partitions 12 gradually decreases from front to back, allowing the clean water to pass over the first partitions 12 and continue to flow backward. Since the cleaning basket 6 moves counterclockwise, the clean water tank 1103 at the back has the most impurities washed off, and the clean water has fewer impurities as it moves forward. As the cleaning basket 6 moves, the wafers in the cleaning basket 6 can be ultrasonically cleaned step by step, gradually reducing the impurities and cleaning solution residue on the wafers and the cleaning basket 6, effectively further improving the quality of wafer cleaning.Finally, the washing basket 6 is transferred to the drying tank 1104. When the air pump 18 is working, the air chamber 1107 on the right is under negative pressure. Therefore, the air chamber 1107 on the right draws in air from the dust removal tank 1106 through the first conduit 19. After the air is filtered, the air pump 18 extracts the gas. The air pump 18 is a rotary vane pump. The rotor rotates eccentrically in the pump chamber, forming a periodically changing volume space. When the vanes rotate continuously in the pump chamber, they draw in gas. The gas moves towards the exhaust port in the pump chamber, and the volume on the exhaust port side gradually decreases, compressing the gas that has been drawn in. The gas can be compressed in the air pump 18, thus pumping the extracted gas into the air chamber 1107 on the left. Then, the heater in the second conduit 20 is activated, and the pressurized air in the air chamber 1107 on the left is pumped in. When the air is sprayed through the second conduit 20, it is heated before being sprayed out from the air holes on the second conduit 20. This allows for hot air drying of the cleaning basket 6 and the wafers in the drying tank 1104, effectively removing moisture from the cleaning basket 6 and the wafers. Then, the cleaning basket 6 is transferred to the material table 1105, where an external robotic arm can remove the cleaned cleaning basket 6 and the wafers inside. The cleaning basket 6 is then re-fixed onto the corresponding electric clamp 5. This achieves integrated operation of dust removal cleaning liquid cleaning and clean water cleaning and drying, facilitating coordination with the production line and enabling efficient and orderly wafer cleaning. It eliminates the need to remove the wafers and send them into the drying equipment for drying, effectively reducing processing steps and minimizing wafer contamination during transfer.

[0032] Example 2: Based on Example 1, according to Figure 1 , Figure 2 and Figures 7-9 As shown, it also includes a transfer box 13, a filter basket 21, and a filter plate 22; two transfer boxes 13 are fixedly connected to the left and right sides of the inner side of the multi-stage cleaning tank 11; the front and rear of the cleaning liquid tank 1101 are each connected to a transfer box 13; the front and rear of the clear water tank 1103 are each connected to a transfer box 13; the inlet and outlet of each pump 14 are each connected to a transfer box 13 on the same side; the position where the outlet of each pump 14 is connected to the transfer box 13 is higher than the position where the inlet of the pump 14 is connected to another transfer box 13; a filter basket 21 is detachably connected to each transfer box 13 connected to the outlet of each pump 14; a filter plate 22 is provided in each filter basket 21.

[0033] The filter plate 22 is inclined inside the filter basket 21, and the side away from the pump 14 is lower than the side close to the pump 14.

[0034] It also includes a first replenishing pipe 15 and a second replenishing pipe 16; the rear of the shock absorber 1 is connected to the first replenishing pipe 15; the transfer box 13 connected to the rear of the cleaning fluid tank 1101 is connected to the first replenishing pipe 15; the front of the shock absorber 1 is connected to the second replenishing pipe 16; the transfer box 13 connected to the front of the clean water tank 1103 is connected to the second replenishing pipe 16.

[0035] Based on the above embodiments, considering the need to circulate the cleaning solution and water, so that impurities on the wafer and cleaning basket 6 can be more easily removed from the wafer and cleaning basket 6 under ultrasonic cleaning combined with the assistance of flowing cleaning solution and water, but impurities are also prone to circulate along with the cleaning solution and water during circulation, a transfer box 13 is set up. When the pump 14 is started, the cleaning solution in the foremost cleaning solution tank 1101 enters the corresponding transfer box 13. The pump 14 then extracts the cleaning solution from the transfer box 13 and pumps it to the rear transfer box 13. The cleaning solution is filtered. In basket 21, impurities in the cleaning solution are intercepted on filter plate 22, thus preventing impurities from re-entering the cleaning solution tank 1101 during the cleaning solution circulation process and contaminating the wafers and cleaning basket 6. Furthermore, setting filter plate 22 in an inclined shape not only increases the filtration area but also effectively prevents impurities from clogging the mesh on filter plate 22 during circulation, thus avoiding obstruction of the circulation process. This would reduce the liquid level of the cleaning solution in the multi-stage cleaning tank 11, ultimately leading to insufficient contact between the wafers and the cleaning solution at the top of the cleaning basket 6, affecting the cleaning efficiency and quality of the wafers.

[0036] The same principle applies to the clear water tank 1103, which purifies the clear water and ensures the clean water cleaning process is circulated. During the circulation of the cleaning solution, some cleaning solution is carried into the interval tank 1102, resulting in the loss of cleaning solution. Therefore, the first replenishment pipe 15 can be set to replenish the cleaning solution to the multi-stage cleaning tank 11 in real time. The first replenishment pipe 15 is set at the transfer box 13. The cleaning solution can also impact the impurities on the filter plate 22, causing the impurities to accumulate at the bottom of the inclined filter plate 22, further preventing the filter plate 22 from being blocked by impurities and affecting the stable operation of the circulation process. Similarly, the second replenishment pipe 16 is set to replenish the clear water. Since the cleaning solution needs to be rinsed again with clear water after cleaning the wafer, the cleaning solution impurities in the clear water will accumulate during the circulation process. The clear water needs to be replaced regularly to completely remove impurities and cleaning solution from the wafer and the cleaning basket 6, ensuring the cleaning effect of the wafer.
