Description

Technical Field

[0001] The invention relates to the technical field of ceramic substrates, in particular to a clamping tool for breaking ceramic sheets. Background Art

[0002] Ceramic substrate refers to a special process board in which copper foil is directly bonded to the surface (single or double sides) of alumina (Al2O3) or aluminum nitride (AlN) ceramic substrate at high temperature. The ultra-thin composite substrate has excellent electrical insulation performance, high thermal conductivity, excellent soft solderability and high adhesion strength. It can be etched with various patterns like PCB boards and has a large current carrying capacity. Therefore, ceramic substrate has become the basic material for high-power power electronic circuit structure technology and interconnection technology.

[0003] Ceramic substrates need to be broken into pieces during the processing, but the existing ceramic breaking solutions require a base plate to be customized according to the specific thickness of the ceramic. A groove consistent with the thickness of the ceramic is opened on the base plate to fix the ceramic for breaking. This results in a small scope of application, and different tooling fixtures need to be matched for ceramics of different specifications and models. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention aims to provide a clamping tool for breaking ceramic pieces.

[0005] In order to achieve the above object, the technical solution of the present invention is as follows:

[0006] The clamping tool for breaking ceramic pieces includes a fixed table, on which a lift platform is arranged that can be raised and lowered, a plurality of openings are opened on one side of the lift platform, and a clamping plate 1 is vertically slidably inserted in the plurality of openings, a clamping plate 2 fixed on the fixed table is slidably arranged on one side of the clamping plate 1, and the clamping plate 2 is slidably connected to the plurality of openings.

[0007] Preferably, the lifting platform is arranged on the output end of the hand-cranked sliding platform, and a fixed bracket fixed on the fixed platform is arranged on one side of the hand-cranked sliding platform.

[0008] Preferably, a slot for inserting the ceramic sheet is provided on a side of the lifting platform away from the hand-cranked sliding platform.

[0009] Preferably, one end of the notch is located on a side of the first clamping plate away from the second clamping plate, and the other end of the notch is located in the same plane as the side of the second clamping plate close to the first clamping plate.

[0010] Preferably, the first clamping plate is located between the hand-cranked sliding platform and the second clamping plate, an electromagnet is arranged on the side of the first clamping plate close to the hand-cranked sliding platform, and a magnetic block is arranged at a position corresponding to the electromagnet on the side of the hand-cranked sliding platform close to the first clamping plate.

[0011] Preferably, the first clamping plate and the second clamping plate are slidably connected via bolts, and a spring wound around the bolts is provided between the first clamping plate and the second clamping plate.

[0012] Preferably, the height of the first clamp and the second clamp is not less than 8 cm, and the height of the first clamp and the second clamp and the lifting platform when vertically sliding is not less than 6 cm.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention uses the electromagnet to push the clamping plate 1 close to the clamping plate 2 by the repulsive force between the electromagnet and the magnetic block until the ceramic sheet is clamped between the clamping plate 1 and the clamping plate 2. The adjustable distance between the clamping plate 1 and the clamping plate 2 makes the device suitable for ceramic sheets of different thicknesses, thereby increasing the application range of the device;

[0015] 2. The present invention supports the bottom of the ceramic sheet by means of the notch on the lifting platform, thereby increasing the stability of the bottom of the ceramic sheet when the first clamping plate and the second clamping plate clamp the ceramic sheet, thereby improving the overall stability of the ceramic sheet;

[0016] 3. The present invention ensures that the clamping plate 1 and the clamping plate 2 can still perform the clamping work when the lifting platform is raised and lowered by the sliding plug connection between the clamping plate 1 and the clamping plate 2 and the lifting platform. The height of the ceramic sheet relative to the clamping plate 1 and the clamping plate 2 is changed by the lifting of the lifting platform, and then the part of the ceramic sheet exposed between the clamping plate 1 and the clamping plate 2 is clamped by pointed pliers to break the ceramic sheet.

[0024] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, those of ordinary skill in the art can propose various structural ways and implementation ways that can be mutually replaced. Therefore, the following specific implementation modes and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as all of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0025] As Figure 1 shown, as the clamping tooling for ceramic wafer breaking of the present invention, it includes a fixed table 1, a hand-cranked sliding table 2 and a first clamping plate 7. As Figure 2 shown, the fixed table 1 is set as a U-shaped plate, and six through holes are equidistantly arranged on one side of the fixed table 1 far away from the opening end. As Figure 3 shown, a fixed bracket 3 is arranged on one side of the hand-cranked sliding table 2, and the fixed bracket 3 is fixed on the top of the fixed table 1 through a positioning pin. A lifting table 4 is arranged at the output end of the hand-cranked sliding table 2. The lifting table 4 is set as an L-shaped plate. The vertical part of the lifting table 4 is connected to the hand-cranked sliding table 2. The horizontal part of the lifting table 4 is located on the top of the fixed table 1, and four openings are arranged on the side of the horizontal part of the lifting table 4 far away from the hand-cranked sliding table 2. The four openings on the lifting table 4 correspond to four of the six through holes in the middle of the fixed table 1. The U-shaped fixed table 1 makes the hand-cranked sliding table 2 located in the middle of the fixed table 1, and the center of gravity being in the middle is beneficial to improving the stability of the device.

[0026] As Figure 4 shown, bolts 10 are slidably arranged at the four corners of the first clamping plate 7. A second clamping plate 8 located on one side of the first clamping plate 7 is also slidably arranged on the four bolts 10, and springs 11 are arranged on the bolts 10 between the first clamping plate 7 and the second clamping plate 8. A ceramic chip 9 is clamped between the first clamping plate 7 and the second clamping plate 8. When the first clamping plate 7 approaches the second clamping plate 8, the spring 11 provides a buffering force to avoid damage to the ceramic chip 9 caused by the movement of the first clamping plate 7. The first clamping plate 7 and the second clamping plate 8 are both vertically arranged, and five openings facing downwards are arranged on both the first clamping plate 7 and the second clamping plate 8. The five openings on the first clamping plate 7 and the second clamping plate 8 are inserted into the four openings on the lifting table 4, and the first clamping plate 7 and the second clamping plate 8 are slidably connected to the lifting table 4. The sliding plug-in connection between the first clamping plate 7 and the second clamping plate 8 and the lifting table 4 ensures that the first clamping plate 7 and the second clamping plate 8 can still perform the clamping work while the lifting table 4 is lifting. By lifting the lifting table 4, the height of the ceramic chip 9 relative to the first clamping plate 7 and the second clamping plate 8 is changed, and then the part of the ceramic chip 9 exposed from the first clamping plate 7 and the second clamping plate 8 is clamped by a pointed pliers for wafer breaking work.

[0027] The height of the clamping plate 1 7 and the clamping plate 2 8 is set to 10 cm, and the height of the vertical sliding of the clamping plate 1 7 and the clamping plate 2 8 and the lifting platform 4 is set to 8 cm, so as to ensure that the clamping plate can stably perform the clamping work. The bottoms of the clamping plate 1 7 and the clamping plate 2 8 are both located in the through hole of the fixed platform 1, the clamping plate 1 7 is located between the clamping plate 2 8 and the hand-cranked sliding platform 2, and the clamping plate 2 8 is fixed on the fixed platform 1. Figure 4 As shown, an electromagnet 6 is provided on the side of the splint 7 close to the hand-cranked sliding table 2, and a magnetic block 5 is provided on the side of the hand-cranked sliding table 2 close to the splint 7 at a position corresponding to the electromagnet 6. The electromagnet 6 works to push the splint 1 7 close to the splint 2 8 by relying on the repulsive force between the electromagnet 6 and the magnetic block 5. The adjustable distance between the splint 1 7 and the splint 2 8 makes the device suitable for ceramic sheets 9 of different thicknesses, thereby increasing the application range of the device.

[0028] like Figure 3 As shown, a slot for inserting the ceramic sheet 9 is provided on the side of the lifting platform 4 away from the hand-cranked sliding platform 2, one end of the slot is located on the side of the clamping plate 7 away from the clamping plate 2 8, and the other end of the slot is located in the same plane as the side of the clamping plate 2 8 close to the clamping plate 1 7. The bottom of the ceramic sheet 9 is supported by the slot on the lifting platform 4, thereby increasing the stability of the bottom clamping of the ceramic sheet 9 when the clamping plates 1 7 and 2 8 clamp the ceramic sheet 9, thereby improving the overall stability of the ceramic sheet 9.

[0029] When in use, the ceramic sheet 9 is placed on the lifting platform 4 between the first clamp 7 and the second clamp 8, and the height of the ceramic sheet 9 relative to the first clamp 7 and the second clamp 8 is adjusted by the hand-cranked sliding platform 2, so as to adjust the exposed height of the ceramic sheet 9, and the electromagnet 6 is used to push the first clamp 7 close to the second clamp 8 so as to clamp the ceramic sheet 9 between the first clamp 7 and the second clamp 8, and finally, the part of the ceramic sheet 9 exposed between the first clamp 7 and the second clamp 8 is clamped by pointed pliers to break the sheet.

[0030] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
