Description

Technical Field

[0001] The invention relates to the technical field of frequency conversion chip processing, and in particular to an etching machine for processing a crystal frequency chip. Background Art

[0002] Quartz has good piezoelectric properties and can be used as a resonator. Quartz crystal frequency chips are cut and etched. The surface of the formed frequency piece is etched in the relevant solution to remove the surface generated during multiple processing. Sub-damage layer, thus facilitating subsequent processing or use.

[0003] When a small-sized frequency converter (thickness of about 0.5 mm, length of about 1 cm, and width of about 0.5 cm) is corroded using an existing etching machine, a large number of frequency converters are generally placed in a carrying basket (a mesh structure installed on a displacement mechanism) of the etching machine, and the frequency converters are stacked at the bottom of the carrying basket. During operation, the carrying basket is immersed in the etching liquid through the displacement mechanism, and the carrying basket is controlled to move back and forth up and down (i.e., shake) or move back and forth up and down + swing, so that the stacked frequency converters are dispersed for corrosion. After each period of corrosion, the carrying basket is transferred to a cleaning tank for cleaning. After cleaning, the carrying basket is transferred to the etching tank again, and this is repeated many times.

[0004] The above operations have the following problems: 1. Use up and down reciprocating motion or up and down reciprocating motion + swinging motion. Rapid mechanical shaking or swinging can easily lead to the accumulation of inverter chips, which are "preferentially dispersed on the surface and residually adhered inside". It is also easy to cause corrosion dead corners, making it impossible for the inverter chips in some areas to be well corroded. Second, fast mechanical jitter or swing can easily cause small-sized inverter chips to break or be damaged; Therefore, the present application provides an etching machine for processing crystal frequency slices to meet the needs.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment: Refer to Figures 1-3 A corrosion machine for processing crystal frequency pieces as shown, including a machine body 1 with a corrosion tank 2 and a cleaning tank 3, a transverse displacement mechanism 5 is arranged on the machine body 1, a longitudinal displacement mechanism 4 is installed on the transverse displacement mechanism 5, and it further includes a bearing unit 6, a liquid flow dispersing unit 7 and an adjusting unit; Carrying unit 6: Installed on the longitudinal displacement mechanism 4, used to carry frequency chips. When the stacked frequency chips are dispersed by a strong liquid flow, the dispersed frequency chips only move within the accommodation cavity of the carrying unit 6; Liquid flow dispersion unit 7: There are two groups, respectively arranged in the etching tank 2 and the cleaning tank 3, used to accelerate the fluid in the etching tank 2 or the cleaning tank 3 and then spray it out to impact the frequency chips in the accommodation cavity of the carrying unit 6; Adjusting unit: Used to control the strong fluid sprayed from top to bottom to disperse the stacked frequency chips.

[0022] As a preferred implementation mode in this embodiment, as Figures 1-9 shown, the carrying unit 6 includes a mounting rod 61 installed on the longitudinal displacement mechanism 4 and a cylindrical water leakage net 64 with a carrying funnel 65 detachably installed at the bottom; The cylindrical water leakage net 64 is hollow, and the upper end is sealed by a top plate 63. The upper end of the top plate 63 is connected to the mounting rod 61 through a connecting rod 62. A hollow tube 66 is provided at the center of the lower end of the carrying funnel 65. A guiding member is installed in the inner cavity of the cylindrical water leakage net 64. The guiding member includes an inverted conical block 616 coaxially arranged with the cylindrical water leakage net 64, and a planar ring plate 617 is arranged on the outer edge of the inverted conical block 616; The adjusting unit includes a low-speed motor 68 with a screw rod 69 installed at the output end and a movable tube 613 slidably penetrating through the hollow tube 66; An anti-corrosion elastic layer 615 is fixed in the inner cavity of the hollow tube 66. A slider 614 is fixed on the movable tube 613. The outer end of the slider 614 slides in a chute provided on the inner wall of the hollow tube 66. A blocking net 612 is installed at the upper end of the movable tube 613; The low-speed motor 68 is installed at the lower end of the mounting rod 61. The lower end of the screw rod 69 is threadedly installed in the threaded cavity of the square rod 610. The lower end of the square rod 610 penetrates through the centers of the top plate 63 and the inverted conical block 616 and extends into the inner cavity of the cylindrical water leakage net 64; The liquid flow dispersion unit 7 includes a pump body 71 installed on the outer wall of the machine body 1. The liquid outlet pipe of the pump body 71 is connected to the first vertical pipe 72. The first vertical pipe 72 is located directly below the movable tube 613. The outer diameter of the first vertical pipe 72 is adapted to the inner diameter of the movable tube 613. An anti-corrosion elastic sleeve is provided on the outer wall of the first vertical pipe 72.

[0023] During use, the loading funnel 65 (made of an elastic and corrosion-resistant material) is detached from the cylindrical water leakage net 64, and the movable tube 613 is moved upward relative to the loading funnel 65 until the slider 614 abuts against the inner wall of the hollow tube 66 and cannot move further, and then a proper amount of frequency conversion chips (keep a proper amount of frequency conversion chips placed in the conical cavity of the loading funnel 65 so that when the initially thrown frequency conversion chips fall into the conical cavity, there is no accumulation of frequency conversion chips at the bottom of the conical cavity, which is conducive to fully dispersing the frequency conversion chips and enabling each frequency conversion chip to be fully corroded) are stacked in the conical cavity of the loading funnel 65 (not exceeding the conical cavity, and try to keep the upper ends of the stacked frequency conversion chips flat). At this time, the movable tube 613 is located above the stacked frequency conversion chips. After loading, the loading funnel 65 is installed on the cylindrical water leakage net 64. After installation (at this time, the lower end of the square rod 610 abuts against the upper end of the retaining net 612), the longitudinal displacement mechanism 4 is controlled by the PLC controller to work, and the cylindrical water leakage net 64 is completely immersed in the corrosion liquid in the corrosion tank 2. During this downward movement, the lower end of the movable tube 612 will be inserted into the upper end of the first vertical tube 72. Then, the pump body 71 and the low-speed motor 63 are controlled to work. The corrosion liquid is sprayed out from the upper end of the movable tube 613. At the same time, the low-speed motor 63 works to drive the screw 69 to rotate, and finally the square rod 610 drives the movable tube 612 to move slowly downward. The strong fluid sprayed out from the movable tube 613 brings up the frequency conversion chips near its periphery. The upward moving frequency conversion chips will contact the inverted conical block 616 (made of an elastic and corrosion-resistant material) and be guided to move outward and disperse. Eventually, they will fall back into the conical cavity due to gravity. When the upper end of the movable tube 613 is flush with the upper end of the hollow tube 66, the low-speed motor 68 stops moving, while the pump body 71 will continue to work until it stops working after reaching the set working time. Then, the longitudinal displacement mechanism 4 and the lateral displacement mechanism 5 are controlled by the PLC controller to work, and the corroded frequency conversion chips are immersed in the cleaning liquid in the cleaning tank 3 and the pump body 71 and the low-speed motor 68 in the cleaning tank 3 are turned on to work for cleaning. The working mode of each component during cleaning is the same as that during corrosion; During the downward movement of the movable tube 613, the frequency conversion pieces near the movable tube 613 are lifted by the strong fluid, resulting in a gap near the movable tube 613. Due to the setting of the conical cavity, the internally stacked frequency conversion pieces move closer to the movable tube 613 under the action of their own gravity (and the flow of a small part of the liquid flow), and thus are lifted and move upward by the strong fluid ejected from the movable tube 613. The lifted frequency conversion pieces will eventually fall into the conical cavity and continue to move closer to the upper end of the movable tube 613, forming a cycle in this way, so that the frequency conversion pieces are constantly thrown up and fall. By using the impact of the strong liquid flow to throw up and disperse the stacked frequency conversion pieces, and under the action of the impact of the liquid flow and their own gravity, the thrown-up frequency conversion pieces constantly move up and down, the stacked frequency conversion pieces can be fully dispersed and each frequency conversion piece can be fully corroded. Moreover, the impact and dispersion by the liquid flow is gentler than rapid mechanical jitter or oscillation, and it is not easy to cause the frequency conversion pieces to break; The liquid flow impact is used to force the corrosive liquid to circulate rapidly in the arc-shaped water leakage net 64. The by-products generated by corrosion can be discharged through the water leakage holes, maintaining a local high-concentration reaction gradient and avoiding the inhibition of the reaction rate by the by-products; the turbulent impact in a shape can destroy the diffusion boundary layer on the surface of the frequency conversion piece, accelerate the contact reaction between the corrosive liquid and the frequency conversion piece, improve the corrosion effect and shorten the corrosion process time; At the beginning, the frequency conversion pieces form a stack. The movable tube 613 is used to impact the frequency conversion pieces in different height spaces from top to bottom, so that the frequency conversion pieces at different levels are orderly thrown up, and each frequency conversion piece can be thrown to a certain height by the liquid flow and then collide with the inverted conical block 616 and be scattered outward (the collision will separate the frequency conversion pieces that are attached together), extending the time for the frequency conversion pieces to be discarded and fall into the conical cavity, which is beneficial to the dispersed corrosion of the frequency conversion pieces and also beneficial to reducing the number and intensity of collisions between the frequency conversion pieces (reducing the damage rate of the frequency conversion pieces). Compared with directly using the fluid to impact the frequency conversion pieces from the bottom of the stacked frequency conversion pieces, the fluid intensity is greater than that of the fluid ejected by the movable tube 613 moving from top to bottom. Otherwise, the stacked frequency conversion pieces cannot be discarded. The strong fluid impact will cause a large number of frequency conversion pieces to be thrown up and move relatively chaotically, easily increasing the number and intensity of collisions between the frequency conversion pieces, and ultimately leading to an increase in the damage rate of the frequency conversion pieces.

[0024] It should be noted that: First, the angle between the inclined plane and the vertical plane of the conical cavity in the loading funnel 54 is controlled within 35° - 55°. If the angle is too small, it is easy to cause the variable-frequency chips moving towards the vicinity of the movable tube 613 to move too fast, resulting in a smaller dispersion range of the variable-frequency chips or failing to ensure that each variable-frequency chip can be discarded to an appropriate height and collide with the inverted conical block 616. If the angle is too large, it is easy to cause the variable-frequency chips moving towards the vicinity of the movable tube 613 to move too slowly, resulting in an extension of the corrosion treatment time. Second, after the corrosion is completed, the pump body 71 stops working, and the low-speed motor 68 will control the screw 69 to rotate in the reverse direction, so that the square rod 610 returns to its original position. At this time, the loading funnel 65 is immersed in the cleaning tank 3. When the loading funnel 65 starts to move downward initially, the lower end of its hollow tube 66 will be inserted into the lower end of the movable tube 613. Due to the frictional resistance generated between the outer wall of the elastic sleeve and the movable tube 13, the movable tube 613 will remain stationary, while the loading funnel 65 will move downward along the movable tube 613 (during this process, the upper end of the movable tube 613 will return to its original position, that is, move above the stacked variable-frequency chips). When the slider 614 abuts against the inner wall of the hollow tube 66, the loading funnel 65 drives the movable tube 613 to move downward together. Third, the blocking net 612 is provided to prevent the moving variable-frequency chips from entering the movable tube 613, and the blocking net 612 can also be replaced with a one-way liquid inlet valve 611, and the one-way liquid inlet valve 611 is installed on the movable tube 613. Fourth, small liquid leakage holes can be provided on the outer wall of the loading funnel 65 (which is made of an elastic material resistant to corrosion) to facilitate the flow of liquid.

[0025] As a preferred implementation manner in this embodiment, it further includes a fluid aggregating unit, which uses the liquid flow to impact the variable-frequency chips stacked in the conical cavity of the loading funnel 65 to accelerate the movement of the variable-frequency chips towards the axis of the loading funnel 65.

[0026] Relying solely on the gravity of the stacked variable-frequency chips themselves (and a small part of the liquid flow) will make the moving speed of the variable-frequency chips very slow (referring to the movement towards the movable tube 613). Therefore, a fluid aggregating unit is provided to accelerate the approaching speed of the stacked variable-frequency chips towards the movable tube 613, which is beneficial to improving the corrosion efficiency of the variable-frequency chips and shortening the corrosion process treatment time.

[0027] As a preferred implementation manner in this embodiment, as Figure 8 and Figure 3 shown, the fluid aggregating unit includes a second vertical tube 73 installed on the liquid outlet pipe. The lower end of the second vertical tube 73 is connected to a fixed ring pipe 77. An activity ring pipe 76 is rotatably arranged on the fixed ring pipe 77. The activity ring pipe 76 is connected to a liquid spraying ring pipe 79 through two relatively arranged connecting pipes 78. A plurality of liquid spraying pipes 710 are arranged on the inner side wall of the liquid spraying ring pipe 79 in a circumferential and obliquely downward manner. An annular net 67 is provided at the upper end of the loading funnel 65. First mounting rings 8 and second mounting rings 9 are respectively provided at the upper end of the annular net 67 and the lower end of the cylindrical water leakage net 64. A plurality of notches are provided on both the first mounting rings 8 and the second mounting rings 9. Fixed screws 10 are rotatably arranged in the notches on the first mounting rings 8, and wing nuts 11 are threadedly connected to the fixed screws 10. Mounting grooves adapted to the wing nuts 11 are provided at positions on the second mounting rings 9 corresponding to the notches.

[0028] When the loading funnel 65 is immersed in place, the loading funnel 65 is located in the annular cavity of the liquid spraying ring pipe 79. When the pump body 71 works, a part of the fluid enters the inner cavity of the liquid spraying ring pipe 79 through the second vertical pipe 73 and is finally sprayed out from the liquid spraying pipe 710. Since the liquid outlet end of the liquid spraying pipe 710 is arranged obliquely downward, when the fluid sprays outwards, a reaction force will be generated. The reaction force causes the liquid distribution ring pipe 79 to rotate relative to the loading funnel 65. The sprayed fluid passes through the annular net 67 to impact the frequency conversion chips stacked in the conical cavity, thereby accelerating the movement of the frequency conversion chips towards the axis of the loading funnel 65 and preventing the frequency conversion chips from staying on the inclined surface of the conical cavity all the time and being unable to be corroded by the components; When disassembling the loading funnel 65, the wing nut 11 can be rotated to move upwards relative to the fixed screw 10. Finally, the fixed screw 10 can be rotated out of the notch to disassemble the loading funnel 65 from the cylindrical water leakage net 64. Reverse operation can install the loading funnel 65 onto the cylindrical water leakage net 64.

[0029] As a preferred implementation manner in this embodiment, a promoting unit is further included to prevent the kinetic energy of the fluid sprayed out by the liquid spraying pipe 710 from being blocked and consumed by the annular net 67, and further promote the movement of the frequency conversion chips towards the axis of the loading funnel 65.

[0030] Due to the existence of the annular net 67, the kinetic energy in the fluid sprayed out from the liquid spraying pipe 710 is lost, resulting in a weakened impact force on the frequency conversion chips. Therefore, the promoting unit is provided to prevent the annular net 67 from causing energy loss to the sprayed fluid.

[0031] As a preferred implementation manner in this embodiment, as Figure 9 and Figure 3 shown, the promoting unit includes a plurality of U-shaped blocks 12 having the same number as the liquid spraying pipes 710 and a floating plate 15 with a positioning rod 16 at the lower end; The plurality of U-shaped blocks 12 are arranged in a circle on the outer wall of the annular net 67. A rectangular limiting cavity 14 adapted to the liquid spraying pipe 710 is provided in the inner cavity of the U-shaped block 12. Liquid inlet holes 13 adapted to the liquid spraying pipe 710 are provided at positions on the annular net 67 corresponding to the U-shaped blocks 12; The lower end of the positioning rod 16 slides through the plate body 17 fixedly arranged on the top plate 63, and the lower end of the positioning rod 16 passes through the positioning holes arranged on the first mounting ring 8 and the second mounting ring 9; The upper and lower ends of the annular net 67 are rotatably connected to the first mounting ring 8 and the carrying funnel 65 respectively.

[0032] When the supporting funnel 65 is immersed in the corrosive liquid or the cleaning liquid, and the liquid spraying pipe 710 moves to the rectangular limiting cavity 14 of the U-shaped block 12, the floating plate 15 is immersed in the liquid and remains stationary due to the buoyancy. As the supporting funnel 65 continues to move downward, the positioning rod 16 is moved out of the positioning holes of the first mounting ring 8 and the second mounting ring 9. After moving out, the liquid spraying pipe 710 continues to move upward relative to the annular net 67 (the liquid spraying pipe 710 moves in the rectangular limiting cavity 14), and finally the liquid outlet of the liquid spraying pipe 710 is aligned with the liquid inlet hole 13 on the annular net 67, and at this time, the movable pipe 613 passes through the first vertical pipe 72 The elastic sleeve arranged on the outer wall squeezes and contacts each other, so that the movable tube 613 is fastened to the first vertical tube 72. When the fluid is ejected from the liquid spraying tube 710, the annular net 67 will be driven to rotate together, and the ejected fluid can enter the conical cavity of the supporting funnel 65 through the liquid inlet hole 13 to impact the stacked frequency converter plates. After the processing is completed, as the supporting funnel 65 moves upward, the positioning rod 16 will first be inserted into the positioning holes provided on the first mounting ring 8 and the second mounting ring 9, and the subsequent liquid spraying tube 710 will be moved out of the rectangular limit cavity 14. In this overshoot, since there is no obstruction of the annular net 67, the loss of fluid kinetic energy can be effectively avoided.

[0033] It should be noted that when the frequency conversion chips are placed in the carrying funnel 65 , the stacking height of the frequency conversion chips is located below the annular net 67 .

[0034] As a preferred implementation in this embodiment, a flow regulating unit is also included to control the intensity of the fluid sprayed from the liquid spraying pipe 710 and the movable pipe 613.

[0035] In actual operation, when the movable tube 613 performs fluid impact on the stacked frequency conversion chips from top to bottom, the scale of the collapse in the stacked frequency conversion chips (that is, the number of frequency conversion chips moving toward the movable tube 613 per unit time increases) will gradually increase from small to large, and then gradually decrease from large to small. In order to ensure that the fluid has sufficient impact energy (and will not cause damage to the frequency conversion chips due to excessive impact), each frequency conversion chip can be thrown to a suitable height. Therefore, a flow adjustment unit is provided, which can automatically adjust the fluid intensity sprayed by the spray pipe 710 and the movable tube 613 as needed.

[0036] As a preferred implementation in this embodiment, Figure 8 , Figure 3 and Figure 4As shown, the flow regulating unit includes two flow regulating valves 74 respectively installed on the first vertical pipe 72 and the second vertical pipe 73 and two unequal-sided U-shaped rods 711 fixedly installed on the outer wall of the movable pipe 613; A first driving tooth set 712 and a second driving tooth set 713 are respectively disposed on the short side and the long side of the unequal-sided U-shaped rod 711. The first driving tooth set 712 and the second driving tooth set 713 both include a plurality of driving teeth arranged in a straight line. The first driving tooth set 712 is located above the second driving tooth set 713. An adjusting gear 75 is fixed on the adjusting rods of the two flow regulating valves 74 .

[0037] After the carrying funnel 65 is immersed in place, the regulating gear 75 on the flow regulating valve 74 is located directly below the U-shaped cavity of the unequal U-shaped rod 711. When the processing work begins, as the movable tube 613 slowly moves downward, the two second driving gear sets 713 located on the long sides will mesh with the corresponding regulating gears 75 and drive the regulating rod to rotate. When the scale of the collapse in the frequency converter piece gradually increases from small to large (i.e., at the beginning, it will slowly collapse in a small scale and finally develop into a rapid and large-scale collapse), the opening and closing degree of the flow regulating valve 74 on the first vertical pipe 72 gradually increases, and the flow rate of the ejected fluid gradually increases, so that there is enough energy to throw the gathered frequency converter pieces to a certain height. Correspondingly, the opening and closing degree of the flow regulating valve 74 on the second vertical pipe 73 gradually decreases, and the velocity of the ejected fluid gradually decreases, so as to avoid further increasing the scale of the collapse in the frequency converter piece; When the scale of the collapse in the frequency converter changes from large to small, the second drive tooth group 713 located on the long side is separated from the adjusting gear 75, and the first drive tooth group 712 located on the short side is engaged with the corresponding adjusting gear 75. As the unequal-sided U-shaped rod 711 continues to move downward, the opening and closing degree of the flow regulating valve 74 on the first vertical pipe 72 gradually decreases. Correspondingly, the opening and closing degree of the flow regulating valve 74 on the second vertical pipe 73 gradually increases (the purpose is to accelerate the movement of the frequency converter toward the movable tube 613). Finally, the two flow regulating valves 74 form a stable state (that is, keep the initial opening and closing degree unchanged), which is conducive to the dispersion and full corrosion of the frequency converter.

[0038] It should be noted that: first, the two regulating gears 75 are arranged at the same height; second, the two flow regulating valves 74 have the same specifications, and the change in the opening and closing degree of the flow regulating valves 74 per unit time is the same.

[0039] As a preferred implementation in this embodiment, Figure 4 As shown, there is a height difference between the lower end of the first driving tooth set 712 and the upper end of the second driving tooth set 713 .

[0040] The height difference is set so that when the flow rate of the fluid sprayed from the first vertical pipe 72 reaches the maximum, it continues to work in this state for a period of time, thereby avoiding serious accumulation of frequency converters near the movable pipe 613.

[0041] As a preferred implementation in this embodiment, Figure 6 As shown, the inverted tapered block 616 is fixedly mounted on the square rod 610 .

[0042] The purpose is to allow the inverted cone block 616 to move with the square rod 610, and to ensure that the discarded frequency conversion sheet can collide with the inverted cone block 616 and disperse outward, so as to avoid the inverted cone block 616 and the frequency conversion sheet being too far away from each other, resulting in the discarded frequency conversion sheet being unable to collide with the inverted cone block 616, and the frequency conversion sheet being unable to disperse outward, and ultimately causing the frequency conversion sheet to accumulate in the axial space of the columnar water flow network 64, making it impossible for the frequency conversion sheet to be fully corroded, and the number of collisions between the frequency conversion sheets increases, thereby increasing the damage rate of the frequency conversion sheets.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
