Description

Technical Field

[0001] This utility model relates to the field of ceramic substrate clamping technology, specifically a ceramic substrate cutting and positioning device. Background Technology

[0002] Ceramic substrates, also known as ceramic base plates, are sheet-like materials that form a supporting base and shell for film circuit components and externally attached components, using electronic ceramics as a substrate. A search revealed a Chinese patent with authorization announcement number CN220006413U, which discloses a tooling fixture for cutting dielectric ceramic substrates, belonging to the field of ceramic substrate fixtures. This invention solves the problems of thermal stress and thermal cracking caused by heat generated during laser cutting, as well as the high cutting loss of ceramic workpieces, affecting cutting accuracy and resulting in poor processing quality. Rotating the bolt body causes the lower pressure plate to move downwards, driving the T-shaped inner block to move down from the inside of the T-shaped slide groove. The lower pressure plate clamps the dielectric ceramic substrate. A water pump draws cooling water, which is then diverted through a branch pipe. The cooling water flows through side pipes and hoses, and is discharged into the interior of the hollow plate through an internal threaded pipe. During laser cutting, the cooling water is sprayed from a nozzle to cool the cut area of ​​the dielectric ceramic substrate, preventing cracks from forming.

[0003] Currently, existing cutting equipment requires positioning the ceramic substrate during cutting to confine it to a specified cutting position. However, since the positioning device lacks an adjustable function, some ceramic substrates that are too wide or too narrow may not be able to be effectively positioned. Utility Model Content

[0004] To address the problem that existing positioning devices cannot adapt to ceramic substrates of different widths, this invention provides a ceramic substrate cutting and positioning device.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows: A ceramic substrate cutting and positioning device includes a cutting table and a bottom movable cutting tool. A hollow strip groove is provided at the center line of the cutting table for the cutting tool to reciprocate. A transverse width adjustment mechanism is provided on both sides of the hollow strip groove. A longitudinal clamping mechanism is provided on the adjacent side of the two transverse width adjustment mechanisms. The clamping position of the longitudinal clamping mechanism is parallel to the hollow strip groove.

[0006] Furthermore, the lateral width adjustment mechanism includes a fixed plate and a push plate. The fixed plate is installed on the top side of the cutting table, and an electric push rod is installed on the outer wall of the fixed plate. The output end of the electric push rod is connected to one side of the push plate.

[0007] The beneficial effects of adopting the above-mentioned further solution are that the fixing plate provides a stable installation base for the electric push rod, ensuring stable transmission of the push rod output force. The electric push rod drives the push plate to move laterally, realizing the operation of lateral positioning of the substrate, reducing human intervention error and improving positioning efficiency.

[0008] Furthermore, limiting crossbars are inserted through both sides of the fixing plate, and one end of each limiting crossbar is connected to both sides of the push plate.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the limiting crossbar is connected to the push plate, which can limit the movement direction of the push plate, ensure that the push plate slides smoothly only in the lateral direction, avoid uneven push force of the electric push rod causing the push plate to tilt, and prevent the substrate from having cutting deviation due to lateral positioning offset.

[0010] Furthermore, the longitudinal pressing mechanism includes a "U"-shaped frame, with bolts inserted at the four corners of the push plate. The push plate is connected to the "U"-shaped frame by bolts. A rotating rod is threaded onto the top surface of the "U"-shaped frame. The bottom end of the rotating rod extends into the interior of the "U"-shaped frame and is connected to a pressure plate. A gasket is connected to the bottom surface of the pressure plate.

[0011] The advantages of adopting the above-mentioned further solution are that the "U"-shaped frame is connected to the push plate by bolts, which facilitates disassembly and replacement. When the "U"-shaped frame or internal components are damaged, the bolts can be unscrewed for quick repair, reducing maintenance costs. The rotating rod on the top surface of the "U"-shaped frame drives the pressure plate to rise and fall longitudinally through threaded transmission. The operator can precisely control the pressing depth of the pressure plate by turning the rotating rod, realizing fine adjustment of the longitudinal clamping force of the substrate, adapting to ceramic substrates with different flatness, ensuring that the substrate fits the cutting table after clamping, and avoiding substrate shaking during cutting. The gasket on the bottom surface of the pressure plate can buffer the pressure of the pressure plate on the substrate, preventing the pressure plate from directly contacting the substrate and causing scratches on the substrate surface, thus ensuring the integrity of the substrate's appearance.

[0012] Furthermore, the pad includes a sheet body, the bottom surface of which is provided with equidistantly distributed anti-slip ridges, the anti-slip ridges being in a perpendicular positional relationship with the hollowed-out strip groove.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the equidistantly distributed anti-slip ridges on the bottom surface of the pad increase the friction between the pad and the ceramic substrate. Especially during the cutting process, when the substrate is affected by the vibration of the cutting tool, the anti-slip ridges can effectively prevent the substrate from sliding longitudinally and improve clamping stability. The anti-slip ridges are perpendicular to the hollowed-out grooves, and their texture direction is consistent with the cutting direction, so they will not interfere with the cutting path. At the same time, the vertical distribution design ensures that the friction force is evenly applied to the substrate surface, avoiding excessive local stress that could lead to substrate damage.

[0014] Furthermore, limiting longitudinal rods are inserted through both sides of the top surface of the "U"-shaped frame, and the bottom ends of the two limiting longitudinal rods are connected to both sides of the top surface of the pressure plate.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the limiting longitudinal rod is connected to the pressure plate, which can limit the lifting direction of the pressure plate, ensure that the pressure plate only moves vertically in the longitudinal direction, avoid the pressure plate being offset when the rotating rod rotates, and prevent the pressure plate from tilting and causing uneven local pressure on the substrate, resulting in chipping.

[0016] Furthermore, the cutting tool includes a saw blade cutter and a linear motor. The linear motor is mounted on the bottom surface of the cutting table. The moving end of the linear motor is connected to one side of the saw blade cutter. The saw blade end face of the saw blade cutter passes through the hollowed-out strip groove and extends to the top of the cutting table.

[0017] The beneficial effects of adopting the above-mentioned further solution are that the linear motor drives the saw blade cutting machine to move back and forth along the hollowed-out slot, realizing the automation of the cutting action, replacing manual pushing of the cutting, ensuring uniform cutting speed and straight path, avoiding cutting skew caused by hand tremors during manual operation, and improving cutting accuracy. The saw blade of the saw blade cutting machine extends through the hollowed-out slot to the top of the cutting table, which can cut the ceramic substrate in one go without multiple reciprocating cuts, shortening the processing time.

[0018] Furthermore, support legs are welded to the four corners of the bottom surface of the cutting table.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the support leg provides stable support for the device, keeps the cutting table in a horizontal state, and avoids the cutting table tilting due to uneven ground, which would cause substrate cutting deviation.

[0020] Compared with the prior art, the beneficial effects of this utility model are: This ceramic substrate cutting and positioning device, through the combined use of a perforated slot, a lateral width adjustment mechanism, and a longitudinal clamping mechanism, allows it to adapt to ceramic substrates of varying widths. The cutting table provides a stable platform for placing and cutting the substrate, while the movable cutting blade at the bottom meets the reciprocating cutting requirements. The perforated slot at the center line provides a reciprocating channel for the cutting blade, preventing collisions with the cutting table and ensuring precise cutting along the substrate's center line, guaranteeing dimensional accuracy. The symmetrical lateral width adjustment mechanisms on both sides can flexibly adjust their spacing according to the width of the ceramic substrate, adapting to the positioning needs of substrates of different specifications. The longitudinal clamping mechanism adjacent to the lateral width adjustment mechanism has its clamping jaws parallel to the perforated slot, stably clamping the substrate longitudinally to prevent it from shifting along the cutting direction during cutting. This balances lateral adaptability and longitudinal stability, preventing cutting skew and edge chipping caused by substrate displacement, thus improving the yield rate. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1-5This utility model provides a technical solution: a ceramic substrate cutting and positioning device, including a cutting table 1 and a bottom movable cutting tool 3. The cutting table 1 provides a stable placement and cutting platform for the ceramic substrate, and the bottom movable cutting tool 3 meets the reciprocating cutting requirements of the substrate. A hollow strip groove 2 is opened at the center line of the cutting table 1 to allow the cutting tool 3 to reciprocate. The hollow strip groove 2 at the center line provides a reciprocating channel for the cutting tool 3, avoiding collision between the tool and the cutting table 1, while ensuring that the cutting path is accurately carried out along the center line of the substrate, ensuring the cutting dimension accuracy. The two sides of the hollow strip groove 2 are symmetrical. Each position is equipped with a lateral width adjustment mechanism 4, and a longitudinal clamping mechanism 5 is provided on each adjacent side of the two lateral width adjustment mechanisms 4. The clamping position of the longitudinal clamping mechanism 5 is parallel to the hollow strip groove 2. The symmetrical lateral width adjustment mechanisms 4 on both sides can flexibly adjust the spacing according to the width of the ceramic substrate to adapt to the positioning requirements of substrates of different specifications. The longitudinal clamping mechanism 5 on the adjacent side of the lateral width adjustment mechanism has its clamping mouth parallel to the hollow strip groove 2, which can stably clamp the substrate in the longitudinal direction to prevent the substrate from shifting along the cutting direction during cutting. It takes into account both lateral adaptability and longitudinal stability, avoids cutting skew and chipping caused by substrate displacement, and improves the yield.

[0025] 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.

[0026] As an embodiment of this utility model, the lateral width adjustment mechanism 4 further includes a fixed plate 401 and a push plate 402. The fixed plate 401 is installed on the top side of the cutting table 1. An electric push rod 404 is installed on the outer wall of the fixed plate 401. The output end of the electric push rod 404 is connected to one side of the push plate 402. The fixed plate 401 provides a stable mounting base for the electric push rod 404, ensuring stable transmission of the push rod output force. The electric push rod 404 drives the push plate 402 to move laterally, realizing the operation of lateral positioning of the substrate, reducing manual intervention error, and improving positioning efficiency. Limiting crossbars 403 are inserted through both sides of the fixed plate 401. One end of the two limiting crossbars 403 is connected to both sides of the push plate 402. The limiting crossbars 403 are connected to the push plate 402, which can limit the movement direction of the push plate, ensuring that the push plate only slides smoothly in the lateral direction, avoiding uneven pushing force of the electric push rod causing the push plate to tilt, and preventing the substrate from having a cutting deviation due to lateral positioning offset.

[0027] As an embodiment of this utility model, the longitudinal pressing mechanism 5 further includes a "U"-shaped frame 501, with bolts inserted at the four corners of the push plate 402. The push plate 402 is connected to the "U"-shaped frame 501 by bolts. A rotating rod 502 is threadedly connected to the top surface of the "U"-shaped frame 501. The bottom end of the rotating rod 502 extends into the interior of the "U"-shaped frame 501 and is connected to a pressure plate 504. A gasket 505 is connected to the bottom surface of the pressure plate 504. The "U"-shaped frame 501 is connected to the push plate 402 by bolts, which facilitates disassembly and replacement. When the "U"-shaped frame or internal components are damaged, the bolts can be unscrewed for quick repair, reducing maintenance costs. The rotating rod 502 on the top surface of the "U"-shaped frame drives the pressure plate 504 to move vertically up and down via a threaded drive. The operator can precisely control the pressing depth of the pressure plate by turning the rotating rod, thereby fine-tuning the longitudinal clamping force of the substrate to adapt to ceramic substrates with different flatness. This ensures that the substrate fits snugly against the cutting table 1 after clamping, preventing the substrate from shaking during cutting. The pad 505 on the bottom surface of the pressure plate can buffer the pressure of the pressure plate on the substrate, preventing the pressure plate from directly contacting the substrate and causing scratches on the substrate surface, thus ensuring the integrity of the substrate's appearance. The pad 505 includes a body 5051, and the bottom surface of the body 5051 is provided with equidistantly distributed anti-slip ridges 5052. The anti-slip ridges 5052 and the hollowed-out strip grooves 2 are in a perpendicular positional relationship. The equidistantly distributed anti-slip ridges 5052 on the bottom surface of the body 5051 can increase the friction between the pad and the ceramic substrate. Especially when the substrate is affected by the vibration of the cutting tool during the cutting process, the anti-slip ridges can effectively prevent the substrate from sliding longitudinally and improve the clamping stability. The anti-slip raised texture 5052 is perpendicular to the hollowed-out strip groove 2, and its texture direction is consistent with the cutting direction, so it will not interfere with the cutting path. At the same time, the vertical distribution design makes the friction force evenly applied to the substrate surface, avoiding excessive local pressure that could cause substrate damage. Limiting longitudinal rods 503 are inserted on both sides of the top surface of the "U"-shaped frame 501. The bottom ends of the two limiting longitudinal rods 503 are connected to the top sides of the pressure plate 504. The connection between the limiting longitudinal rods 503 and the pressure plate 504 can limit the lifting direction of the pressure plate, ensuring that the pressure plate only moves vertically in the longitudinal direction, avoiding the pressure plate shifting when the rotating rod rotates, and preventing the pressure plate from tilting and causing uneven local pressure on the substrate, resulting in chipping.

[0028] In one embodiment of this utility model, the cutting tool 3 further includes a saw blade cutter 301 and a linear motor 302. The linear motor 302 is mounted on the bottom surface of the cutting table 1. The moving end of the linear motor 302 is connected to one side of the saw blade cutter 301. The end face of the saw blade of the saw blade cutter 301 passes through the hollowed-out strip groove 2 and extends to the top of the cutting table 1. The linear motor 302 drives the saw blade cutter 301 to move back and forth along the hollowed-out strip groove 2, thereby automating the cutting action, replacing manual pushing of the cutter, ensuring uniform cutting speed and a straight path, avoiding cutting skew caused by hand tremors during manual operation, and improving cutting accuracy. The saw blade of the saw blade cutter extends through the hollowed-out strip groove to the top of the cutting table, which can cut the ceramic substrate in one go without multiple reciprocating cuts, shortening the processing time.

[0029] As an embodiment of this utility model, further, support legs 6 are welded to the four corners of the bottom surface of the cutting table 1. The support legs 6 provide stable support for the device, keep the cutting table 1 in a horizontal state, and avoid the cutting table 1 tilting due to uneven ground, thereby causing substrate cutting deviation.

[0030] Specifically, the working principle of this ceramic substrate cutting and positioning device is as follows: During use, the ceramic substrate to be cut is first placed on the top surface of the cutting table 1, aligning the center line of the substrate with the hollowed-out strip groove 2. The lateral width adjustment mechanism 4 on both sides of the hollowed-out strip groove is activated: the electric push rod 404 on the outer wall of the fixed plate 401 drives the push plate 402 to move laterally towards the substrate. The limiting crossbars 403 on both sides of the fixed plate restrict the push plate to slide smoothly only laterally until the push plates on both sides are in contact with the sides of the substrate, completing the lateral positioning of the substrate and adapting to substrates of different widths. Then, the longitudinal clamping mechanism 5 is operated: the rotating rod 502 on the top surface of the "U"-shaped frame 501 is turned, and the pressure plate 504 is driven to descend longitudinally through the threaded transmission. The limiting longitudinal rods 503 on both sides of the "U"-shaped frame ensure that the pressure plate moves vertically until the pad 505 on the bottom surface of the pressure plate is in contact with the top surface of the substrate. The anti-slip ridges 5052 on the bottom surface of the pad increase the friction and prevent the substrate from sliding longitudinally, thus achieving a stable longitudinal clamping of the substrate. At the same time, the pad buffers the pressure to prevent the substrate from being scratched. Finally, the cutting tool 3 is started: the linear motor 302 on the bottom surface of the cutting table 1 drives the saw blade cutting machine 301 to move back and forth along the hollowed-out strip groove 2. The saw blade extends through the hollowed-out strip groove to the top of the cutting table, automatically cutting the clamped substrate. The linear motor ensures that the cutting speed is uniform and the path is straight. The saw blade can cut the substrate in one go, shortening the processing time.
