Description

Technical Field

[0001] This invention relates to the field of crystal coating equipment technology, and more specifically to a crystal silvering fixture. Background Technology

[0002] A quartz crystal oscillator, also known as a quartz crystal resonator, is an electronic device that generates resonant frequencies and is widely used in various electronic products. A quartz crystal oscillator mainly consists of three parts: a base, a crystal, and a housing. The base has two pins arranged side-by-side. One end of the crystal is soldered to the base, electrically connecting the crystal to the two pins. The housing is pressed against the base, sealing the crystal inside.

[0003] A crystal silvering fixture is a positioning tool used to assist in crystal coating (i.e., metal layer deposition). A traditional crystal silvering fixture includes an upper clamping plate, an upper mask, a positioning plate, a lower mask, and a lower clamping plate. The positioning plate has multiple accommodating cavities, each an independent structure. The crystal is placed in one of these accommodating cavities, and the upper and lower clamping plates are then tightened with screws to complete crystal positioning. Subsequently, the crystal silvering fixture is placed in a vapor deposition equipment for vapor deposition. The metal deposition material adheres to the front, back, and sides of the crystal through exposure grooves on the upper and lower masks, thus completing the crystal coating. However, traditional crystal silvering fixtures have low space utilization, a limited number of accommodating cavities, and require complete disassembly of the upper clamping plate and upper mask to insert or remove the crystal from the accommodating cavity, making loading and unloading inconvenient. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a crystal silvering fixture that offers higher space utilization, more accommodating cavities, and easier loading and unloading of materials within the same size.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A crystal silver clamp includes an upper clamping assembly, a lower clamping assembly, and a sealing component; The upper clamping assembly has an upper clamping plate and an upper mask; The lower clamping assembly includes a lower clamping plate, a lower mask, and a positioning plate; The upper mask and the lower mask are both disposed between the upper clamping plate and the lower clamping plate, and the positioning plate is disposed between the upper mask and the lower mask; The positioning plate has a number of positioning strips arranged at intervals. The length direction of the positioning strips is perpendicular to the arrangement direction of the positioning strips. The upper mask, the lower mask and two adjacent positioning strips enclose and form a long groove. The length direction of the long groove is the same as the length direction of the positioning strips. The long groove forms a number of accommodating cavities connected end to end along its length direction. Each accommodating cavity can accommodate a crystal. The upper mask is provided with a first exposure groove corresponding to each of the accommodating cavities, the lower mask is provided with a second exposure groove corresponding to each of the accommodating cavities, and at least one side of each accommodating cavity has a side exposure groove. The upper clamping plate is provided with a first hollow groove, the first exposed groove is connected to the first hollow groove, and the first hollow groove is connected to the outside. The lower clamping plate is provided with a second hollow groove, the second exposed groove is connected to the second hollow groove, and the second hollow groove is connected to the outside. One end of the long groove extends to the end of the positioning strip to form a material port. The material port allows crystals to slide into the long groove one by one to fill the corresponding receiving cavity. The crystals that have completed vapor deposition in the receiving cavity can slide out of the material port along the length of the long groove. The sealing member is detachably provided at the material port and the sealing member isolates the material port from the outside. A plurality of locking elements are provided between the upper clamping component and the lower clamping component, which can keep the upper clamping component and the lower clamping component in a clamped state or release them from a clamped state.

[0006] In one embodiment, a plurality of spreading members and a plurality of limiting members are provided between the upper clamping assembly and the lower clamping assembly. The spreading members can spread the upper clamping assembly to keep the upper clamping assembly and the lower clamping assembly in a separated state. With the cooperation of the limiting members and the spreading members, the upper mask separates from the positioning plate.

[0007] In one embodiment, the spreading member is a compression spring, one end of which abuts against the upper clamping plate, and the other end of which abuts against the positioning plate or the lower clamping plate. The limiting member is a limiting screw, which has a head and a rod. The upper clamping plate is provided with a plurality of third connecting holes, and the lower clamping plate is provided with a plurality of fourth connecting holes. The rod passes through the third connecting hole and is threaded into the fourth connecting hole. The rod moves along its axial direction through the third connecting hole. The head restricts the upper clamping assembly from moving away from the lower clamping assembly.

[0008] In one embodiment, a plurality of first connectors are provided between the upper clamping plate and the upper mask, and the first connectors install the upper mask on the upper clamping plate. A plurality of second connectors are provided between the lower mask, the positioning plate and the lower clamping plate, and the second connectors install the lower mask and the positioning plate on the lower clamping plate.

[0009] In one embodiment, the upper clamping plate is provided with a plurality of connecting ribs, which are arranged at intervals along the length direction of the positioning strip. The connecting ribs extend along the length direction perpendicular to the positioning strip. Adjacent connecting ribs are spaced apart to form a through groove, which is connected to the outside. Each connecting rib has a plurality of notches corresponding to the long grooves on the side facing the mask. The notches are connected to the adjacent through grooves. All the through grooves and notches constitute the first hollow groove.

[0010] In one embodiment, the upper clamping plate has two longitudinal beams and several transverse beams. The longitudinal beams extend along the length direction perpendicular to the positioning strip. Several transverse beams are spaced apart between the two longitudinal beams. The two ends of the transverse beams are respectively connected to the corresponding longitudinal beams. Adjacent transverse beams and two longitudinal beams enclose a clamping area. The clamping area is provided with the first hollow groove. Adjacent transverse beams are connected by the connecting ribs.

[0011] In one embodiment, the side exposure groove is a trapezoidal groove, and the inner walls of both ends of the trapezoidal groove along the length of the positioning strip are formed with guide slopes. The two guide slopes are arranged in a figure-eight shape, and the distance h4 between the two guide slopes gradually decreases in the direction away from the center of the long groove.

[0012] In one embodiment, the sealing component has a sealing groove that extends along the length direction perpendicular to the positioning strip and is open towards the material outlet. The upper clamping assembly and the lower clamping assembly are disposed in the sealing groove on the side near the material outlet. The edge of the material outlet abuts against the inner wall of the sealing groove. The upper clamping plate abuts against the inner top wall of the sealing groove, and the lower clamping plate abuts against the inner bottom wall of the sealing groove.

[0013] In one embodiment, the sealing member has a main body and an upper pressure plate and a lower pressure plate spaced apart on one side of the main body. The main body, the upper pressure plate, and the lower pressure plate surround to form the sealing groove. The upper pressure plate abuts against the upper clamping plate, and the lower pressure plate abuts against the lower clamping plate.

[0014] In one embodiment, the main body is further provided with an extension, which is located on the side of the upper pressure plate away from the lower pressure plate. A gap is maintained between the extension and the upper pressure plate. Several bolts are provided on the extension. The upper pressure plate is a thin plate structure. One end of the bolt can extend into the gap to press the upper pressure plate and produce a slight deformation in the direction closer to the lower pressure plate.

[0015] Compared with existing technologies, this invention has significant advantages and beneficial effects. Specifically, by setting several spaced positioning strips on the positioning plate, the upper mask, lower mask, and two adjacent positioning strips enclose and form a long groove. The long groove forms multiple accommodating cavities connected end to end, each of which can accommodate one crystal. One end of the long groove forms a material inlet, and a detachable sealing element is provided at the material inlet to isolate it from the outside, thereby preventing the metal vapor deposition material from adhering to the edge of the material inlet and to adhering to the inner wall of the long groove. During loading, the material inlet is tilted upwards, and the crystals to be vapor-deposited are directly slid one by one from the material inlet. The crystals are inserted into the long groove to fill the corresponding receiving cavities, so that the crystals in two adjacent receiving cavities are aligned end to end. Then, the locking device is tightened to keep the upper clamping assembly and the lower clamping assembly clamping the crystals. Finally, the material outlet is sealed with a sealing device. When unloading, the sealing device is removed, the locking device is loosened to release the upper clamping assembly and the lower clamping assembly from the clamping state, and the material outlet is tilted downwards. The crystals that have completed vapor deposition slide out one by one from the material outlet along the length of the long groove. Thus, the space utilization rate of this fixture is higher and the number of receiving cavities is greater for the same size. The crystals slide in and out of the receiving cavities, making loading and unloading more convenient.

[0016] To more clearly illustrate the structural features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: Attached Figure Description

They are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0021] like Figure 1-16 As shown, the present invention discloses a crystal silvering clamp 10, including an upper clamping component 20, a lower clamping component 30, and a sealing component 40.

[0022] The upper clamping assembly 20 has an upper clamping plate 21 and an upper mask 22; the lower clamping assembly 30 has a lower clamping plate 31, a lower mask 32, and a positioning plate 33; the upper mask 22 and the lower mask 32 are both disposed between the upper clamping plate 21 and the lower clamping plate 31, and the positioning plate 33 is disposed between the upper mask 22 and the lower mask 32. The length L of the upper clamping plate 21 and the lower clamping plate along the length direction of the positioning strip 331 is 260 mm - 270 mm, and the width D of the upper clamping plate 21 and the lower clamping plate is 100 mm - 110 mm.

[0023] The positioning plate 33 has a plurality of positioning strips 331 arranged at intervals. The length direction (e.g., the Y-axis direction) of the positioning strips 331 is perpendicular to the arrangement direction (e.g., the X-axis direction) of the positioning strips 331. The upper mask 22, the lower mask 32 and two adjacent positioning strips 331 enclose each other to form an elongated groove 34. The length direction of the elongated groove 34 is the same as the length direction of the positioning strips 331. The elongated groove 34 has a plurality of accommodating cavities 341 connected end to end along its length direction. Each accommodating cavity 341 can accommodate a crystal 50.

[0024] The upper mask 22 is provided with a first exposure groove 221 corresponding to the accommodating cavity 341, and the lower mask 32 is provided with a second exposure groove (not shown) corresponding to the accommodating cavity 341. At least one side of the accommodating cavity 341 has a side exposure groove 3411. The first exposure groove 221 and the second exposure groove are both connected to the accommodating cavity 341 and the side exposure groove 3411. The first exposure groove 221 and the second exposure groove are both prior art. For example, the accommodating cavity 341 has the side exposure groove 3411 on both sides along the arrangement direction of the positioning strip 331.

[0025] The upper clamping plate 21 is provided with a first hollow groove 211, the first exposed groove 221 is connected to the first hollow groove 211, and the first hollow groove 211 is connected to the outside. The lower clamping plate 31 is provided with a second hollow groove (not shown), the second exposed groove is connected to the second hollow groove, and the second hollow groove is connected to the outside. The second hollow groove has the same structure as the first hollow groove 211.

[0026] One end of the elongated groove 34 extends to the end of the positioning strip 331, forming a feed port 342. The feed port 342 allows crystals 50 to slide into the elongated groove 34 one by one to fill the corresponding receiving cavity 341. Crystals 50 that have completed vapor deposition in the receiving cavity 341 can slide out of the feed port 342 along the length of the elongated groove 34. Crystals 50 in two adjacent receiving cavities 341 are positioned end-to-end. The sealing member 40 is detachably installed at the feed port 342, sealing the feed port 342. Isolation from the outside world: For example, the feed port 342 is a funnel-shaped feed port 342, and the width of the funnel-shaped feed port 342 gradually increases from the inside to the outside along the length direction of the positioning strip 331. By setting the sealing member 40 to isolate the feed port 342 from the outside world, during the vapor deposition of the crystal 50, the metal vapor deposition material is prevented from adhering to the edge of the feed port 342 and from entering the long groove 34 and adhering to the inner wall of the long groove 34, preventing the crystal 50 from being unable to smoothly enter and exit the long groove 34, and also achieving a cleaning-free effect on the feed port 342.

[0027] A plurality of locking members 23 are provided between the upper clamping component 20 and the lower clamping component 30, and the plurality of locking members 23 can keep the upper clamping component 20 and the lower clamping component 30 in a clamped state or release them from a clamped state.

[0028] The locking component 23 is a locking screw. The upper clamping plate 21 has several first connecting holes 212, and the lower clamping plate 31 has several second connecting holes 311. The locking screw passes through the first connecting holes 212 and the second connecting holes 311 in sequence to connect the upper clamping plate 21 and the lower clamping plate 31, thereby keeping the first clamping assembly and the second clamping assembly in a clamped state. In use, rotating the locking screw in the forward direction will clamp the first clamping assembly and the second clamping assembly, and rotating the locking screw in the reverse direction will release the clamp.

[0029] When the upper clamping assembly 20 and the lower clamping assembly 30 are in a clamped state, the thickness h1 of the crystal 50 along the Z-axis is slightly larger than the distance h2 between the upper mask 22 and the lower mask 32. For example, the thickness h1 of the crystal 50 is 0.3 mm, and the thickness h1 of the crystal 50 is 0.02 mm - 0.05 mm larger than the distance h2. Preferably, the thickness h1 of the crystal 50 is 0.04 mm larger than the distance h2. By setting the thickness h1 of the crystal 50 along the Z-axis to be slightly larger than the distance h2 between the upper mask 22 and the lower mask 32, when the upper clamping assembly 20 and the lower clamping assembly 30 are in a clamped state, the upper mask 22 and the lower mask 32 clamp the two sides of the crystal 50, which can prevent the crystal 50 from sliding along the long groove 34 during the evaporation process, keep the crystal 50 stable, and improve the evaporation quality of the crystal 50.

[0030] A plurality of spreading members 24 and a plurality of limiting members 25 are provided between the upper clamping assembly 20 and the lower clamping assembly 30. The spreading members 24 can spread the upper clamping assembly 20 to keep the upper clamping assembly 20 and the lower clamping assembly 30 in a separated state. With the cooperation of the limiting members 25 and the spreading members 24, the upper mask 22 is separated from the positioning plate 33. The upper masks 22 maintain a distance h3 between each other. The distance h3 is greater than the thickness h1 of the crystal 50 and less than twice the thickness of the crystal 50. By setting the limiting member 25 and the spreading member 24, the upper mask 22 is separated from the positioning plate 33, so that the upper mask 22 and the lower mask 50 are separated by a distance h3. The distance h3 is greater than the thickness h1 of the crystal 50 and less than twice the thickness of the crystal 50. This ensures that only one crystal 50 is allowed to enter the chute from the feed port 342 at a time, thereby preventing two stacked crystals 50 from sliding into the long groove 34 from the feed port 342 at the same time. When the upper clamping assembly 20 and the lower clamping assembly 30 are clamped, it prevents the two stacked crystals 50 from damaging the upper mask 22 and the lower mask 32. For example, the distance h3 is 0.2 mm greater than the thickness h1 of the crystal 50.

[0031] The spreading member 24 is a pressure spring. One end of the pressure spring abuts against the upper clamping plate 21, and the other end of the pressure spring abuts against the positioning plate 33 or the lower clamping plate 31. For example, the other end of the pressure spring abuts against the positioning plate 33. The limiting member 25 is a limiting screw. The limiting screw has a head 251 and a rod 252. The upper clamping plate 21 is provided with a plurality of third connecting holes 213, and the lower clamping plate 31 is provided with a plurality of fourth connecting holes 312. The rod 252 passes through the third connecting hole and is threaded into the fourth connecting hole. The rod 252 moves along its axial direction through the third connecting hole 213. The limiting screw is stationary relative to the lower clamping plate 31. The head 251 is located on the side of the upper clamping plate 21 away from the lower clamping plate 31. The head 251 restricts the upper clamping assembly 20 from moving away from the lower clamping assembly 30. When the pressure spring spreads the upper clamping assembly 20, the head 251 abuts against the upper clamping plate 21. By employing a pressure spring, after the upper clamping assembly 20 and the lower clamping assembly 30 are released from clamping, the spring force of the pressure spring can be used to open the upper clamping assembly 20, thereby separating the upper mask 22 from the positioning plate 33. This expands the height of the feed port 342 along the Z-axis, allowing the crystal 50 to be deposited to be loaded into the long groove 34, or allowing the crystal 50 to slide out of the long groove 34 after depositing. The feeding and discharging are convenient, quick, smooth, and efficient. The limiting component 25 uses a limiting screw, which can be rotated in the forward or reverse direction to adjust the distance between the head 251 and the upper clamping plate 21, thereby adjusting the degree to which the pressure spring opens the upper clamping assembly 20 away from the lower clamping assembly 30, so that the crystal 50 can better enter and exit the long groove 34.

[0032] The upper clamping plate 21 is provided with a mounting groove 214, and the pressure spring is disposed in the mounting groove 214. One end of the pressure spring abuts against the inner wall of the mounting groove 214 away from the lower clamping plate 31.

[0033] For example, the third connecting hole 213 communicates with the mounting groove 214, and the pressure spring is sleeved on the outside of the rod portion 252. By setting the pressure spring to be sleeved on the rod portion 252, the assembly structure of the pressure spring and the limiting screw is compact and occupies little space.

[0034] A plurality of first connectors 26 are provided between the upper clamping plate 21 and the upper mask 22, and the first connectors 26 mount the upper mask 22 onto the upper clamping plate 21. A plurality of second connectors 35 are provided between the lower mask 32, the positioning plate 33, and the lower clamping plate 31, and the second connectors 35 mount the lower mask 32 and the positioning plate 33 onto the lower clamping plate 31. By providing the first connectors 26 and the second connectors 35, the upper mask 22 and the upper clamping plate 21 are kept stably connected, as are the positioning plate 33, the lower mask 32, and the lower clamping plate 31.

[0035] The first connector 26 is a first pin, which passes through the upper mask 22 and the upper clamping plate 21. The side of the upper mask 22 away from the upper clamping plate 21 abuts against the first limiting block 261 on the first pin to prevent the upper mask 22 from detaching from the upper clamping plate 21. The second connector 35 is a second pin, which passes through the positioning plate 33, the lower mask 32, and the lower clamping plate 31. The side of the positioning plate 33 away from the lower clamping plate 31 abuts against the second limiting block 351 on the second pin to prevent the positioning plate 33 from detaching from the lower mask 32 from the lower clamping plate 31. It is understood that both the first pin and the second pin can be replaced by screws.

[0036] The upper clamping plate 21 is provided with a plurality of first pin holes 215, and the upper mask 22 is provided with first clearance holes 222 corresponding to the first pin holes 215. The first pin passes through the first clearance hole 222 and is connected to the first pin hole 215. The first pin is tightly fitted to the first pin hole 215 or threadedly connected.

[0037] The lower clamping plate 31 is provided with a plurality of second pin holes, and the positioning plate 33 and the lower mask 32 are each provided with a second clearance hole 332 corresponding to the second pin holes. The second pin passes through the second clearance hole 332 and is connected to the second pin hole. The second pin is tightly fitted to the second pin hole or threadedly connected.

[0038] A plurality of first clearance grooves 216 are provided between the upper mask 22 and the upper clamping plate 21. The first clearance grooves 216 allow the second limiting block 351 to extend into them. The positioning plate 33 is provided with a second clearance groove 333, which allows the first limiting block 261 to extend into it. Specifically, the second clearance groove 333 extends onto the lower clamping plate 31. By providing the first clearance grooves 216 and the second clearance grooves 333, with the first clearance groove 216 allowing the second limiting block 351 to extend into it and the second clearance groove 333 allowing the first limiting block 261 to extend into it, the upper clamping assembly 20 and the lower clamping assembly 30 are tightly clamped together in the clamping state, that is, the positioning plate 33 is tightly fitted with the upper mask 22.

[0039] The upper clamping plate 21 is provided with a plurality of connecting ribs 217, which are arranged at intervals along the length direction of the positioning strip 331. The connecting ribs 217 extend along the length direction perpendicular to the positioning strip 331. Adjacent connecting ribs 217 maintain a distance to form a through groove 2111, which penetrates the opposite sides of the upper clamping plate 21 and communicates with the outside. Each connecting rib 217 has a plurality of notches 2112 on the side facing the upper mask 22, which correspond one-to-one with the long groove 34. The notches 2112 communicate with the adjacent through grooves 2111. All the through grooves 2111 and notches 2112 constitute the first hollow groove 211. The part of the connecting rib 217 other than the notches 2112 abuts against the upper mask 22. By setting several through slots 2111 and several notches 2112, the through slots 2111 are connected to the outside, and the notches 2112 are connected to the adjacent through slots 2111. The notches 2112 correspond one-to-one with the long slots 34. All the through slots 2111 and notches 2112 constitute the first hollowed-out slot 211. During the vapor deposition process, the metal vapor deposition material flows freely in the through slots 2111 and notches 2112, making it easy for the metal vapor deposition material to enter the first exposed slot 221 and the side exposed slot 3411 through the notches 2112 to vapor deposit on the outer surface of the crystal 50. The vapor deposition is sufficient and the effect is good.

[0040] The upper clamping plate 21 has two longitudinal beams 218 and several transverse beams 219. The longitudinal beams 218 extend along a length direction perpendicular to the positioning strip 331. The transverse beams 219 are spaced apart between the two longitudinal beams 218. The two ends of each transverse beam 219 are connected to the corresponding longitudinal beam 218. Adjacent transverse beams 219 and two longitudinal beams 218 enclose a clamping area 27. There are four clamping areas 27. Each clamping area 27 has the first hollow groove 211. Adjacent transverse beams 219 are connected by connecting ribs 217. The spacing h5 between adjacent transverse beams 219 is 50 mm-60 mm. By setting two longitudinal beams 218 and several transverse beams 219, with the two ends of each transverse beam 219 connected to the corresponding longitudinal beam 218, the upper clamping plate 21 has high strength and is not easily deformed.

[0041] The locking element 23, the spreading element 24, and the limiting element 25 are all located on the crossbeam 219, and the locking element 23 is also located on the longitudinal beam 218 away from the feed inlet 342. By arranging the locking element 23, the spreading element 24, and the limiting element 25 on the crossbeam 219, the connection points of the upper clamping plate 21 and the lower clamping plate 31 are evenly distributed, the space is used rationally, the structure is compact, and the upper clamping assembly 20 and the lower clamping assembly 30 are more tightly clamped when they are engaged.

[0042] The first pin includes several fine pins 26' and several coarse pins 26''. The fine pins 26' are tightly connected to a portion of the connecting ribs 217. Fine pins 26' are provided on the longitudinal beam 218 near the feed opening 342. The coarse pins 26'' are provided on the crossbeam 219. The coarse pins 26'' are threadedly connected to the upper clamping plate 21. The second clearance groove 333 corresponding to the coarse pins 26'' penetrates the lower clamping plate 31 on the side away from the upper clamping plate 21.

[0043] The structure of the lower clamping plate 31 is roughly the same as that of the upper clamping plate 21. The lower clamping plate 31 has the longitudinal beam 218, the transverse beam 219 and the clamping area 27. The longitudinal beam 218 on the lower clamping plate 31 corresponds one-to-one with the longitudinal beam 218 on the upper clamping plate 21. The transverse beam 219 on the lower clamping plate 31 corresponds one-to-one with the transverse beam 219 on the upper clamping plate 21. The clamping area 27 on the lower clamping plate 31 corresponds one-to-one with the clamping area 27 on the upper clamping plate 21.

[0044] One end of the upper clamping plate 21 and the lower clamping plate 31 can be inserted into the rotating base 60 on the vapor deposition equipment. The rotating base 60 is provided with a slot 61. One end of the upper clamping plate 21 and the lower clamping plate 31 is provided with an insertion part 28, which can be inserted into the slot 61. The insertion part 28 is provided with positioning notches 281 on both sides along the length direction of the positioning strip 331. The positioning notches 281 allow positioning protrusions (not shown) in the slot 61 to be inserted. By providing the insertion part 28 and the positioning notches 281 on the insertion part 28, it is convenient for the fixture to be inserted into the rotating base 60 on the vapor deposition equipment, making installation convenient.

[0045] The insertion part 28 is also provided with multiple arc-shaped grooves 29, and the rotating base 60 is also provided with ball screws 62 corresponding to the arc-shaped grooves 29 one by one. The ball screws 62 extend into the slots 61, and the movable steel balls on the ball screws 62 engage with the arc-shaped grooves 29 to prevent the insertion part 28 from disengaging from the slots 61. Specifically, the arc-shaped grooves 29 on the upper clamping plate 21 are recessed on the side of the upper clamping plate 21 away from the lower clamping plate 31, and the arc-shaped grooves 29 on the lower clamping plate 31 are recessed on the side of the lower clamping plate 31 away from the upper clamping plate 21. The multiple arc-shaped grooves 29 are distributed at intervals along the length direction of the positioning strip 331. By setting the arc-shaped grooves 29 and the ball screws 62, the engagement of the movable steel balls on the ball screws 62 with the arc-shaped grooves 29 can prevent the insertion part 28 from disengaging from the slots 61, making it convenient to insert and remove the clamp from the slots 61, convenient to install onto the rotating base 60, and convenient to disassemble from the rotating base 60.

[0046] The side exposure groove 3411 is a trapezoidal groove. Guide slopes 3412 are formed on the inner walls of both ends of the trapezoidal groove along the length of the positioning strip 331. The two guide slopes 3412 are arranged in a V-shape, and the distance h4 between the two guide slopes 3412 gradually decreases towards the center away from the long groove 34. The included angle β between the guide slope 3412 and the short side 3413 of the trapezoidal groove is 100-150 degrees. By setting the side exposure groove 3411 as a trapezoidal groove, guide slopes 3412 are formed on the inner walls of both ends of the trapezoidal groove along the length of the positioning strip 331. The two guide slopes 3412 are arranged in a figure-eight shape, and the distance h4 between the guide slopes 3412 gradually decreases in the direction away from the center of the receiving cavity 341. The guide slopes 3412 can guide the edges and corners of the crystal 50, preventing the edges and corners of the crystal 50 from getting stuck in the side exposure groove 3411 and being unable to move, so that the crystal 50 slides smoothly along the long groove 34, thereby making the crystal 50 feed and discharge smoothly.

[0047] The positioning plate 33 includes two separate positioning pieces 334, which are stacked along the Z-axis. Since the positioning strip 331 is formed by etching away excess material on the positioning plate 33 during actual processing, if the positioning plate 33 is thick, the etching depth will be large, which will lead to a large deviation in the width of the positioning strip 331. Therefore, the positioning plate 33 is divided into two positioning pieces 334. Each positioning piece 334 is thinner, so the positioning strip 331 etched on the positioning piece 334 has higher precision. Finally, the two positioning pieces 334 are stacked to obtain the required positioning strip 331. The thickness of each positioning piece 334 is 0.13 mm, and the interval between two adjacent positioning strips 331 is 1.02 mm, that is, the width k1 of the long groove 34 is 1.02 mm, and the width k2 of the crystal 50 along the length direction perpendicular to the positioning strip 331 is 1.0 mm.

[0048] The sealing component 40 has a sealing groove 401, which extends along the length direction perpendicular to the positioning strip 331. The sealing groove 401 is open towards the material outlet 342. The upper clamping component 20 and the lower clamping component 30 are located in the sealing groove 401 on the side near the material outlet 342. The edge of the material outlet 342 abuts against the inner wall of the sealing groove 401. The upper clamping plate 21 abuts against the inner top wall of the sealing groove 401, and the lower clamping plate 31 abuts against the inner bottom wall of the sealing groove 401. Specifically, the side of the upper clamping component 20 and the lower clamping component 30 near the material outlet 342 abuts against the inner wall of the sealing groove 401. That is, the side walls of the upper clamping plate 21, the upper mask 22, the lower clamping plate 31, the lower mask 32, and the positioning plate 33 near the material outlet 342 all abut against the inner wall of the sealing groove 401.

[0049] The sealing component 40 has a main body 41, and an upper pressure plate 42 and a lower pressure plate 43 spaced apart on one side of the main body 41. The main body 41, the upper pressure plate 42, and the lower pressure plate 43 enclose the sealing groove 401. The upper pressure plate 42 abuts against the upper clamping plate 21, and the lower pressure plate 43 abuts against the lower clamping plate 31. For example, the sealing groove 401 is open at both ends along the length direction perpendicular to the positioning strip 331.

[0050] The main body 41 is also provided with an extension 44, which is located on the side of the upper pressure plate 42 away from the lower pressure plate 43. A gap 402 is maintained between the extension 44 and the upper pressure plate 42. Several bolts 45 are provided on the extension 44, which are distributed along the length direction perpendicular to the positioning strip 331. The upper pressure plate 42 is a thin plate structure with a thickness of about 1 mm. One end of the bolt 45 can extend into the gap 402 to press the upper pressure plate 42 towards the lower pressure plate 43, causing a slight deformation. This allows the upper pressure plate 42 to press the upper clamping plate 21, and the lower pressure plate 43 to press the lower clamping plate 31. By using the bolts 45 to press the upper pressure plate 42 to press the upper clamping plate 21, the bolts 45 are prevented from acting directly on the upper clamping plate 21, thus preventing repeated tightening of the bolts 45 from causing wear and pitting on the surface of the upper clamping plate 21. Furthermore, the contact area between the upper pressure plate 42 and the upper clamping plate 21 is large, resulting in a better pressing effect.

[0051] The main body 41, upper pressure plate 42, lower pressure plate 43 and extension 44 are integrally molded from plastic material.

[0052] It should be noted that the sealing element 40 of the present invention can also be a disposable adhesive tape (not shown), which is pasted on the edge of the feed opening 342 to isolate the feed opening 342 from the outside.

[0053] In addition to using the upper mask 22 and the lower mask 32 to press the two sides of the crystal 50 to restrict the crystal 50 from sliding along the long groove 34 during the vapor deposition process, the present invention can also provide several push rods (not shown) on the sealing member 40 that correspond one-to-one with the long groove 34. The push rods are inserted into the long groove 34 from the feed port 342 to press against the nearest crystal 50, while the crystal 50 farthest from the feed port 342 abuts against the inner wall of the long groove 34. This method can also restrict the crystal 50 from sliding along the long groove 34 during the vapor deposition process.

[0054] In addition to a pressure spring, the opening component of the present invention can also use a support block (not shown). The support block is placed between the upper clamping plate 21 and the lower clamping plate 31 to keep the upper clamping component 20 and the lower clamping component 30 in a separated state. At this time, the opposite sides of the support block abut against the upper clamping plate 21 and the lower clamping plate 31 respectively. When the upper clamping component 20 and the lower clamping component 30 need to be clamped together, the support block can be moved out between the upper clamping plate 21 and the lower clamping plate 31.

[0055] It should also be noted that the locking component 23 of the present invention can also be a locking claw (similar to an alligator clip). The locking claw has a first clamping arm, a second clamping arm, and a torsion spring. The first clamping arm and the second clamping arm are rotatably connected by a rotating shaft. The torsion spring is sleeved outside the rotating shaft, and the two ends of the torsion spring abut against the first clamping arm and the second clamping arm, respectively. The torsion spring makes one end of the first clamping arm and the second clamping arm always tend to maintain the clamping state, and the torsion spring makes the other end of the first clamping arm and the second clamping arm always tend to maintain the open state. In use, several locking claws are clamped around the periphery of the upper clamping plate 21 and the lower clamping plate 31. The first clamping arm on the locking claw clamps the upper clamping plate 21, and the second clamping arm clamps the lower clamping plate 31, thus completing the clamping of the upper clamping component 20 and the lower clamping component 30. When it is necessary to release the clamping, the locking claw can be removed.

[0056] The method of using this invention is as follows: First, loosen the locking member 23. With the cooperation of the spreading member 24 and the limiting member 25, the upper clamping assembly 20 and the lower clamping assembly 30 remain separated. Next, tilt the material inlet 342 upward and open it. Align each material inlet 342 with the output end of the external feeding track (the feeding track is connected to the vibrating plate). The feeding track slides the crystals 50 to be vapor-deposited one by one from the material inlet 342 into the long groove 34. The crystals 50 fill the corresponding receiving cavity 341 with their ends touching each other until the long groove 34 is filled. All accommodating cavities 341 are filled; then the locking member 23 is locked, keeping the upper clamping assembly 20 and the lower clamping assembly 30 in a clamped state. At this time, the upper mask 22 and the lower mask 32 press against both sides of the crystal 50; then the sealing member 40 is installed at the material port 342 to isolate the material port 342 from the outside; finally, the plug-in part 28 is inserted into the slot 61 on the rotating seat 60, and the movable steel ball on the ball screw 62 is engaged in the arc groove 29 to complete the installation of the crystal silvering fixture 10 on the vapor deposition equipment. After the crystal 50 is vapor deposited, the crystal silvering fixture 10 is removed from the rotating seat 60, the sealing member 40 is removed, the locking member 23 is released, and under the action of the spreading member 24, the upper clamping assembly 20 and the lower clamping assembly 30 remain separated, the material port 342 is tilted downward and opened, and the vapor-deposited crystal 50 slides out from the material port 342.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made to the above embodiments based on the actual technology of the present invention shall still fall within the scope of the technical solution of the present invention.
