Description

Technical Field

[0001] The utility model relates to the technical field of chip packaging equipment, in particular to a sintering fixture based on a double-sided HTCC metal ceramic cavity. Background Art

[0002] The double-sided HTCC metal-ceramic cavity is a high-temperature co-fired ceramic material with excellent high-temperature performance and mechanical strength. It is usually composed of a multi-layer ceramic substrate and a metal conductive layer, which is formed by co-firing at high temperature. This cavity has good dimensional stability, excellent high-temperature insulation performance and excellent corrosion resistance, so it has a wide range of applications in high-temperature environments. During the high-temperature co-firing process, the shape of the double-sided HTCC metal-ceramic cavity needs to remain stable to ensure the dimensional accuracy and geometry of the final product. The sintering fixture can fix the ceramic substrate and the metal conductive layer together according to the design requirements to prevent them from deformation or displacement at high temperatures. The structure of the sintering fixture mainly includes upper and lower clamps, and the closed space of the sintering cavity is formed between the upper and lower clamps. These clamps are usually made of double-sided HTCC metal-ceramic materials to ensure stability and heat resistance in high-temperature environments.

[0003] However, the upper and lower clamps are usually connected by bolts. First, holes are opened in the upper and lower clamps of the clamp at pre-designed positions, and then they are connected together by bolts and nuts. However, pre-machining of bolt holes may limit the flexibility of the clamp, making it only possible to use bolts of specific specifications and models for connection. When the layout of components inside the clamp needs to be adjusted, the bolt holes need to be re-machined, which increases the cost and time of maintenance and adjustment. Utility Model Content

[0026] like Figure 1-4 As shown, the sintering fixture based on the double-sided HTCC metal ceramic cavity proposed by the utility model includes an upper clamping plate 1 and a lower clamping plate 2, and also includes: a connecting mechanism installed on the upper clamping plate 1 and the lower clamping plate 2 to adjust the component layout inside the fixture so that no holes are required; and a tightening mechanism arranged on the connecting mechanism to tightly connect the connected ends of the connecting mechanism.

[0027] Further, the connection mechanism includes a support rod 3, on which a pair of first connecting rods 31 and second connecting rods 32 are rotatably connected, and a first supporting card seat 4, a second supporting card seat 5, a third supporting card seat 6 and a fourth supporting card seat 7 are clamped on each right angle of the upper clamp plate 1, and a rotation groove is provided on the first supporting card seat 4, the second supporting card seat 5, the third supporting card seat 6 and the fourth supporting card seat 7, and the function of the rotation groove is to allow the connection ends of the first connecting rod 31, the second connecting rod 32, the third connecting rod 41, the fourth connecting rod 51, the first U-shaped rod 61 and the second U-shaped rod 71 to rotate. The first supporting card seat 4, the second supporting card seat 5, the third supporting card seat 6 and the fourth supporting card seat 7 are all provided with grooves for tightly clamping the corresponding right-angle ends of the upper clamp plate 1 and the lower clamp plate 2, and the end of the second connecting rod 32 away from the support rod 3 is rotatably connected to the second supporting card seat 5, and the end of the first connecting rod 31 away from the support rod 3 is rotatably connected to the first supporting card seat 4.

[0028] The connection mechanism further includes a pair of fourth connecting rods 51 rotatably connected to the middle of the second support base 5 and the third support base 6, a pair of third connecting rods 41 are rotatably connected to the middle of the first support base 4 and the fourth support base 7, a second U-shaped rod 71 is rotatably connected to the fourth support base 7, a pair of limiting slide grooves 72 are provided at one end of the second U-shaped rod 71 close to the first U-shaped rod 61, a limiting rod 62 is fixedly connected to one end of the first U-shaped rod 61 close to the second U-shaped rod 71 for sliding into the limiting slide groove 72, and when the limiting rod 62 slides into the limiting slide groove 72, the direction of relative movement of the first U-shaped rod 61 and the second U-shaped rod 71 can be kept horizontal. The third support base 6 is rotatably connected to the first U-shaped rod 61 corresponding to the second U-shaped rod 71.

[0029] Furthermore, the tightening mechanism includes a support plate 63 fixedly connected to the first U-shaped rod 61, a spiral rod 64 is rotatably connected to the support plate 63, a handle 65 is fixedly connected to one end of the spiral rod 64 away from the support plate 63, a U-shaped stopper 66 for clamping one end of the first U-shaped rod 61 and the second U-shaped rod 71 is spirally connected to the spiral rod 64, and an inclined stopper groove 68 is provided on the U-shaped stopper groove 66 for clamping the first U-shaped rod 61 and the second U-shaped rod 71 to move in the same direction, and the function of the inclined stopper groove 68 is to make the distance between the connected ends of the first U-shaped rod 61 and the second U-shaped rod 71 smaller as the U-shaped stopper block 66 moves. A clamping groove 67 is provided inside the inclined stopper groove 68, and when the clamping groove 67 clamps the first U-shaped rod 61 and the second U-shaped rod 71, the connection mechanism clamps the upper clamping plate 1 and the lower clamping plate 2 to the tightest state.

[0030] In this embodiment, when a sintering fixture based on a double-sided HTCC metal ceramic cavity is required, it is only necessary to clamp the grooves on the first support base 4, the second support base 5, the third support base 6 and the fourth support base 7 to the right-angled ends of the upper clamping plate 1 and the lower clamping plate 2. Then, the first U-shaped rod 61 and the second U-shaped rod 71 are rotated so that the opposite ends of the first U-shaped rod 61 and the second U-shaped rod 71 are closely attached to the upper clamping plate 1 and the lower clamping plate 2. Then, a pair of limiting clamping rods 62 on the first U-shaped rod 61 are clamped into the limiting sliding groove 72 on one end of the second U-shaped rod 71, and at this time, the inclined retaining groove 68 on the U-shaped retaining block 66 is clamped to the first U-shaped rod 61 and the second U-shaped rod 71. Finally, the handle 65 can be turned to drive the spiral rod 64 to rotate. Since the spiral rod 64 and the U-shaped stop block 66 are spirally connected, the U-shaped stop block 66 moves along the spiral rod 64 toward the first U-shaped rod 61 and the second U-shaped rod 71 until the clamping groove 67 in the inclined stop groove 68 clamps the opposite ends of the first U-shaped rod 61 and the second U-shaped rod 71, so that the connected ends of the first U-shaped rod 61 and the second U-shaped rod 71 can reach the tightest state, which is simple and easy to operate. When the connecting mechanism and the tightening mechanism need to be removed from the upper clamping plate 1 and the lower clamping plate 2, it is only necessary to reverse the above operation, which will not be repeated here.
