Description

Technical Field

[0001] This utility model relates to the field of ceramic substrate positioning, and in particular to a dielectric ceramic substrate positioning device. Background Technology

[0002] Dielectric ceramic substrates are thin sheet or plate-shaped materials made from ceramic materials and play a crucial role in microwave frequency circuits. Primarily acting as a dielectric material, they not only support and insulate circuits but also enable specific functions such as resonance and filtering.

[0003] In the processing of ceramic substrates, the cutting stage is crucial. First, the ceramic substrate needs to be cut to the appropriate size, part of which requires the use of diamond wire cutters. Specifically, the ceramic substrate is clamped using a column (usually a stone pillar). Once stable, it is then bonded and fixed to a base, firmly securing the substrate. Next, the diamond wire cutter is used to cut downwards from top to bottom. When cutting to the bottom of the ceramic material, the wire must fit tightly against the base to ensure a complete cut. Therefore, both ends of the wire are bent (to ensure the wire remains in close contact with the base). However, during bending and contact with the base, the diamond grain layer attached to the wire is prone to cracking and detachment, directly preventing subsequent cutting operations from proceeding properly. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes a positioning device for dielectric ceramic substrates.

The power unit drives the first block to move on the top of the base until both ends of the ceramic sheet are respectively located inside the groove, and the clamping part fixes the ceramic sheet. At this time, there is a gap between the bottom of the ceramic sheet and the upper surface of the base. When the cutting line moves to the gap position, the ceramic sheet is completely cut off.

[0006] Preferably, the power unit is an electric push rod, and the output end of the electric push rod is mounted on the first block.

Detailed Implementation

[0015] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0016] According to one embodiment of the present invention, in conjunction with Figures 1-3 As shown.

[0017] A dielectric ceramic substrate positioning device comprises a base 1 with at least four fixing holes for securely connecting the base 1 to a cutting device. Electric push rods 2 are symmetrically mounted on the top of the base 1 via mounting brackets and bolts. A first block 3 is bolted to the output end of the electric push rod 2. The first block 3 has a groove 4 for placing the ceramic substrate, with the bottom of the groove 4 higher than the upper surface of the base 1. Furthermore, a clamping part is installed inside the first block 3 for clamping and fixing the ceramic substrate.

[0018] In actual operation, the electric push rod 2 drives the first piece 3 to move on top of the base 1 until both ends of the ceramic sheet fall into the grooves 4. Then, the ceramic sheet is fixed by the clamping part, at which point a gap is formed between the bottom of the ceramic sheet and the top of the base 1. When the cutting line moves to the position of this gap, the ceramic sheet will be completely cut off.

[0019] Specifically, the clamping part includes a slot 7 formed inside the first block 3, with both sides of the slot 7 penetrating the first block 3. A screw 9 is mounted at the center of the slot 7 via a second block 8. The screw 9 movably passes through the second block 8, can rotate around its own axis, and is designed as a forward and reverse screw. Extension rods 11 are welded to both ends of the screw 9, extending to the outside of the first block 3 to facilitate rotation of the screw 9. A clamping plate 5 is mounted on the outside of the screw 9 via a connecting part. The clamping plate 5 is slidably installed inside a slot 4, and two clamping plates 5 are provided in each slot 4. Rotating the extension rods 11 drives the screw 9 to rotate, the connecting part moves along the screw 9, and in turn drives the clamping plate 5 to move within the slot 4 until the ceramic sheet is clamped and fixed.

[0020] Furthermore, the connecting part includes a sleeve 12 that is threaded onto the outside of the screw 9. The inner side of the sleeve 12 away from the first block 3 has a movable sealing contact with the extension rod 11, and the outer side of the sleeve 12 also has a movable sealing contact with the inner side of the groove 7. This movable sealing effect is achieved by covering the inner and outer sides of the sleeve 12 with a rubber layer, which serves as a sealing layer. In addition, an L-shaped connecting rod 6 is welded to the outer side of the sleeve 12, and the other end of the connecting rod 6 is welded and fixed to the clamping plate 5. When the sleeve 12 moves, the clamping plate 5 is driven to move via the connecting rod 6.

[0021] In this embodiment, to prevent the screw 9 from moving along its own axis, a limiting ring 10 is welded and fixed to the outside of the screw 9. Two limiting rings 10 are provided, located on both sides of the second block 8, to ensure the stable operation of the screw 9.

[0022] Working principle: When in use, first start the electric push rod 2. The electric push rod 2 drives the first block 3 to move on the base 1 until both ends of the ceramic sheet can be placed in the grooves 4 of the first block 3 on both sides. At this time, there is a gap between the bottom of the ceramic sheet and the top of the base 1, so that part of the lower end of the ceramic sheet is suspended in the air. Then rotate the extension rod 11 to make the screw 9 rotate, thus driving the sleeve 12 to move on the screw 9. The sleeves 12 on both sides move in opposite directions. When the sleeves 12 move, the clamping plate 5 moves synchronously through the connecting rod 6 until the clamping plate 5 clamps and fixes the ceramic sheet. After fixing, the cutting work can be carried out using the cutting line.

[0023] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
