Description

Technical Field

[0001] This utility model relates to the field of ceramic substrate processing technology, specifically to a positioning and calibration device for an easily fixed alumina ceramic substrate. Background Technology

[0002] Alumina ceramic substrates are substrates made of alumina ceramic materials, possessing excellent electrical insulation properties, high thermal conductivity, superior solderability, and high adhesion strength. They are typically manufactured using a high-temperature sintering process, which involves directly bonding copper foil to the surface of the alumina ceramic substrate at high temperatures to form single-sided or double-sided ultrathin composite substrates.

[0003] A positioning and calibration device for alumina ceramic substrates, as disclosed in Chinese Patent Publication No. CN217521970U, includes a ceramic substrate body. A housing is located below the ceramic substrate body, and four support columns are fixed to the lower surface of the housing. An adjustment mechanism is located inside the housing, and a positioning mechanism is mounted on the adjustment mechanism. The adjustment mechanism includes a first screw rod rotatably connected to the left side wall of the housing cavity via a bearing seat, penetrating and extending to the right side of the housing. Two threaded blocks are threadedly connected to the outer surface of the first screw rod, and a fixing rod is fixed to the upper surface of the threaded blocks, penetrating and extending to the top of the housing. This alumina ceramic substrate positioning and calibration device, by incorporating an adjustment mechanism, allows for the adjustment of the distance between the two fixing plates by rotating a handwheel, thereby enabling the placement of different alumina ceramic substrates. Compared to traditional alumina ceramic substrate positioning and calibration devices, it has a wider range of applications and can operate on ceramic substrates of different sizes.

[0004] In the process of realizing this application, the inventors discovered that the technology has at least the following problems: Although the above technical solution can place different alumina ceramic substrates, its calibration method is to perform positioning calibration by squeezing the alumina ceramics from both sides, which makes it impossible to calibrate the center of the alumina ceramic substrate to the processing center. Moreover, its positioning method is to squeeze the sides of the alumina ceramic substrate, which will affect the overall processing of the alumina ceramic substrate. Therefore, further improvements can be made. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides the following technical solution: an easily fixed alumina ceramic substrate positioning and calibration device, comprising a base, four sliding grooves arrayed in the top of the base, a limiting groove extending through the bottom wall of the sliding grooves, a positioning and calibration component for centering and calibrating the ceramic substrate disposed within the sliding grooves and the limiting grooves, an installation groove disposed in the center of the base, a reduction motor fixedly installed in the installation groove, and a slot disposed on the top side of the base between two adjacent sliding grooves, an auxiliary positioning component disposed within the slot.

[0006] As an optimization, the positioning calibration component is slidably connected to a slider inside the limiting groove. A screw is screwed into the inside of the slider. A support plate is fixedly installed on the top side of the slider, and the support plate is slidably connected in the slide groove. A clamping plate is fixedly installed on the top of the support plate. A transmission component that drives the screw to rotate is provided in the mounting groove. The transmission component drives the screw to rotate inside the slider, which in turn causes the slider to slide along the inner wall of the limiting groove. Therefore, the support plate drives the clamping plate to slide closer to the outside of the ceramic substrate.

[0007] As an optimization, the transmission component includes a driving bevel gear fixedly installed at one end of the output shaft of the geared motor, and a driven bevel gear fixedly installed at one end of the screw that enters the mounting groove. The driven bevel gear and the driving bevel gear are meshed and connected. When the geared motor is started, the driving bevel gear will be driven to rotate, which in turn will drive the screw to rotate through the driven bevel gear that is meshed with the driving bevel gear.

[0008] As an optimization, four sets of driven bevel gears are arranged around the array of driving bevel gears, and all of them are meshed and connected to the top side of the driving bevel gears. Through the four sets of driven bevel gears meshing with the driving bevel gears, the four sets of screws can rotate synchronously, so that the surrounding clamping plates can slide synchronously relative to each other, thereby ensuring that the center intersection point of the four sets of clamping plates remains stable.

[0009] As an optimization, the auxiliary positioning component includes a sleeve inserted into a slot, and a suction cup is fixedly installed on the top of the sleeve. By placing the ceramic substrate on the top side of the suction cup and pressing it, the suction cup can be adsorbed onto the bottom side of the ceramic substrate.

[0010] As an optimization, a fixing plate is fixedly installed on the outer side of the sleeve, a fixing ring is fixedly installed on the inner wall of the slot, and the fixing ring is sleeved on the outer side of the sleeve. A spring is fixedly installed between the fixing plate and the fixing ring. A negative pressure tube is sealed and inserted into the inside of the sleeve. The other end of the negative pressure tube is connected to a negative pressure machine. A trigger switch for controlling the negative pressure machine is provided between the fixing plate and the fixing ring. The fixing plate is elastically supported by the spring, which facilitates the downward movement of the suction cup under pressure.

[0011] As an optimization, the trigger switch includes a pressing head fixedly installed on the bottom side of the fixing plate, and a pressing switch is installed on the top side of the fixing ring corresponding to the pressing head.

[0012] The beneficial effects of this utility model are:

[0013] This easy-to-fix alumina ceramic substrate positioning and calibration device drives four sets of active bevel gears to rotate synchronously by starting a reduction motor. This drives four screws to rotate synchronously inside the slider through driven bevel gears that mesh with the active bevel gears. This ensures that the center intersection of the four sets of clamping plates remains stable. Therefore, when the clamping plates slide relative to each other and are clamped to the outside of the ceramic substrate, the ceramic substrate can be clamped and fixed at the center processing position, thereby enabling the positioning and calibration of the processing position of the alumina ceramic substrate.

[0014] This easy-to-fix alumina ceramic substrate positioning and calibration device allows the ceramic substrate placed on the top side of the suction cup to be adsorbed by the suction cup. At the same time, it also moves the fixing plate downward, which in turn causes the pressing head to press the switch downward, thereby turning on the negative pressure machine. The negative pressure in the negative pressure tube further adsorbs the ceramic substrate, thereby further improving the stability of the alumina ceramic substrate positioning.

[0020] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] 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.

[0022] Please see Figure 1-2 A positioning and calibration device for easily fixed alumina ceramic substrate includes a base 1. Four sliding grooves 2 are arrayed in the top of the base 1. A limiting groove 3 is formed through the bottom wall of the base 1 at the sliding grooves 2. A positioning and calibration component 4 for centering and calibrating the ceramic substrate is set inside the sliding grooves 2 and the limiting groove 3. An installation groove is formed in the center of the base 1. A reduction motor 5 is fixedly installed in the installation groove. A slot 6 is formed on the top side of the base 1 between two adjacent sliding grooves 2. An auxiliary positioning component 7 is set inside the slot 6.

[0023] Please see Figure 3 The positioning calibration component 4 is slidably connected to the slider 8 inside the limiting groove 3. The slider 8 is screwed with a screw 9 inside. The top side of the slider 8 is fixedly installed with a support plate 10, and the support plate 10 is slidably connected in the slide groove 2. The top of the support plate 10 is fixedly installed with a clamping plate 11. A transmission component that drives the screw 9 to rotate is provided in the mounting groove. The transmission component will drive the screw 9 to rotate inside the slider 8, which will cause the slider 8 to slide along the inner wall of the limiting groove 3. Therefore, the support plate 10 will drive the clamping plate 11 to slide relatively close to the outside of the ceramic substrate, thereby positioning the ceramic substrate.

[0024] Please see Figure 3 The transmission components include a drive bevel gear 12 fixedly installed at one end of the output shaft of the geared motor 5, and a driven bevel gear 13 fixedly installed at one end of the screw 9 that passes into the mounting groove. The driven bevel gear 13 and the drive bevel gear 12 are meshed and connected. When the geared motor 5 is started, the drive bevel gear 12 will be driven to rotate, which in turn will drive the screw 9 to rotate through the driven bevel gear 13 that is meshed with the drive bevel gear 12.

[0025] Please see Figure 3 The driven bevel gears 13 are arranged in four sets around the driving bevel gears 12, and are all meshed and connected to the top side of the driving bevel gears 12. Through the four sets of driven bevel gears 13 meshing with the driving bevel gears 12, the four sets of screws 9 can rotate synchronously, so that the clamping plates 11 around the perimeter can slide synchronously relative to each other, thereby ensuring that the center intersection of the four sets of clamping plates 11 remains stable, thus clamping and fixing the ceramic substrate in the center position.

[0026] Please see Figure 4The auxiliary positioning component 7 includes a sleeve 14 inserted into the slot 6. A suction cup 15 is fixedly installed on the top of the sleeve 14. By placing the ceramic substrate on the top side of the suction cup 15 and pressing it, the suction cup 15 can be adsorbed on the bottom side of the ceramic substrate, thereby enabling the ceramic substrate to be positioned and installed from the bottom side, avoiding affecting the processing of the front side of the ceramic substrate.

[0027] Please see Figure 4 A fixing plate 16 is fixedly installed on the outer side of the sleeve 14, and a fixing ring 17 is fixedly installed on the inner wall of the slot 6. The fixing ring 17 is sleeved on the outer side of the sleeve 14. A spring 18 is fixedly installed between the fixing plate 16 and the fixing ring 17. A negative pressure tube 19 is sealed and inserted into the inside of the sleeve 14. The other end of the negative pressure tube 19 is connected to a negative pressure machine. A trigger switch for controlling the negative pressure machine is provided between the fixing plate 16 and the fixing ring 17. The fixing plate 16 is elastically supported by the spring 18, which facilitates the downward movement of the suction cup 15 under pressure. At the same time, the negative pressure in the negative pressure tube 19 will further adsorb the ceramic substrate, improving the stability of the positioning.

[0028] Please see Figure 4 The trigger switch includes a pressing head 20 fixedly installed on the bottom side of the fixed plate 16, and a pressing switch 21 installed on the top side of the fixed ring 17 corresponding to the pressing head 20. Pressing the suction cup 15 will drive the fixed plate 16 to move downward, which will drive the pressing head 20 to press the pressing switch 21 downward, thereby controlling the opening and closing of the negative pressure machine.

[0029] In use, the alumina ceramic substrate to be processed is first placed on the top side of the base 1. Then, by starting the reduction motor 5, the four sets of active bevel gears 12 will rotate synchronously. In turn, the driven bevel gears 13, which are meshed with the active bevel gears 12, will drive the four screws 9 to rotate synchronously inside the slider 8. Therefore, the slider 8 will slide along the inner wall of the limiting groove 3, thus ensuring that the center intersection of the four sets of clamping plates 11 remains stable. So when the clamping plates 11 slide relative to each other and are clamped to the outside of the ceramic substrate, the ceramic substrate can be clamped and fixed at the center processing position.

[0030] Then, pressing down on the ceramic substrate will allow the suction cup 15 to adhere to the bottom side of the ceramic substrate, thus positioning the ceramic substrate. At the same time, pressing the ceramic substrate will also move the fixing plate 16 downward, which will cause the pressing head 20 to press down on the pressing switch 21, thereby controlling the negative pressure machine to turn on. Therefore, the negative pressure in the negative pressure tube 19 will further adhere to the ceramic substrate, improving the stability of the positioning.

[0031] In summary, this easy-to-fix alumina ceramic substrate positioning and calibration device, by starting the reduction motor 5 to drive the four sets of active bevel gears 12 to rotate synchronously, will drive the four screws 9 to rotate synchronously inside the slider 8 through the driven bevel gears 13 that mesh with the active bevel gears 12. This ensures that the center intersection of the four sets of clamping plates 11 remains stable. Therefore, when the clamping plates 11 slide relative to each other and are clamped to the outside of the ceramic substrate, the ceramic substrate can be clamped and fixed at the center processing position, thereby enabling the positioning and calibration of the processing position of the alumina ceramic substrate.

[0032] By pressing the ceramic substrate placed on the top side of the suction cup 15, the suction cup 15 can adsorb the bottom side of the ceramic substrate. At the same time, it will also drive the fixing plate 16 to move downward, which will drive the pressing head 20 to press the pressing switch 21 downward, thereby turning on the negative pressure machine. Therefore, the negative pressure in the negative pressure tube 19 will further adsorb the ceramic substrate, thereby further improving the stability of the positioning of the alumina ceramic substrate.
