Description

Technical Field

[0001] The invention relates to the technical field of AMB production fixture equipment, in particular to an AMB-based production loading fixture. Background Art

[0002] AMB is a technology used to manufacture high-performance ceramic substrates. AMB substrates are widely used in power electronic equipment, automotive electronics, aerospace, and industrial control. The ceramic material and the metal layer are tightly bonded through active metal brazing technology. This substrate has high thermal conductivity, high mechanical strength, excellent electrical insulation performance and low thermal expansion coefficient. It is widely used in the packaging of power semiconductor modules. In the metal brazing process, the loading fixture is a key tool for combining metal foil with ceramic substrate under high temperature conditions. Its main function is to clamp and fix the AMB substrate to facilitate its loading into the heating furnace for the brazing process.

[0003] A Chinese patent with publication number CN220753401U discloses an AMB loading fixture, the structure of which includes a fixture body, a groove is provided on the upper surface of the fixture body, a first multi-stage loading transfer processing groove is provided in the middle of one side of the upper end of the fixture body located at the groove, a second multi-stage loading transfer processing groove is provided in the middle of the other side of the upper end of the fixture body located at the groove, a first guide seat is positioned at one side of the fixture body, a second guide seat is positioned at the front end of the fixture body, and a first bolt is positioned between the first guide seat and the fixture body. The AMB loading fixture described in the utility model has a curved groove, on which copper, base and top copper are placed. Since it can be loaded by directly grabbing and keeping aligned by hand during loading, the left and right grooves are for facilitating the transfer of all loaded products to the fixture that can be loaded individually in multiple stages while the upper copper sheet is loaded.

In addition, this fixing method may also affect the uniformity of heat distribution of the substrate in the heating furnace, because the shape and depth of the groove may not be flexible enough to fully adapt to the thermal expansion characteristics of different substrates, thereby affecting the quality and consistency of the brazing process.

The sliding block 33 is provided with two groups, which are symmetrically distributed on both sides of the inner part of the outer frame 1. The sliding block 33 is a convex shape. One end of each group of sliding blocks 33 is fixedly connected to two groups of telescopic rods 1 32. The bottom ends of the four groups of telescopic rods 1 32 are fixedly connected to the bottom plate 31. The top ends of each two groups of telescopic rods 1 32 are fixedly connected to a group of top blocks 34. The two groups of top blocks 34 are symmetrically distributed on both sides of the inner part of the outer frame 1. The side ends of each group of top blocks 34 are fixedly connected to a connecting frame 35. One end of the connecting frame 35 is fixedly connected to a placing table 36.

The adjusting member 2 10 passes through the top block 34 in the support member 2 4 and is threadedly connected to it. Among them, when the adjusting member 1 2 and the adjusting member 2 10 are rotated, the adjusting member 1 2 and the adjusting member 2 10 respectively drive the top block 34 in the support member 1 3 and the top block 34 in the support member 3 5 to move along the direction of the adjusting member 1 2 and the adjusting member 2 10, so that the position of the support member 1 3 and the support member 2 4 changes, and the spacing between the support member 1 3, the support member 2 4 and the support member 3 5 is adjusted.

[0020] Reference Figures 4 to 5The side end of the outer frame 1 is penetrated by a sliding groove 23, and the sliding groove 23 is provided with four groups, which are symmetrically provided on both sides of the outer frame 1. The adjusting member 1 2 and the adjusting member 2 10 respectively penetrate the two corresponding sliding grooves 23 and are slidably connected with the sliding grooves 23.

Through the threaded rod 1 21 and the threaded rod 22 with opposite threads, when the adjusting member 2 and the adjusting member 2 10 are rotated, the two groups of support members 1 3 and support members 2 4 located on both sides of the support member 3 5 are driven to move in the opposite or opposite directions, and the distance between the support members 1 3, support members 2 4 and support members 3 5 is enlarged or reduced, so that the placement table 36 on the support members 1 3, support members 2 4 and support members 3 5 can stably support the AMB substrates 6 of different sizes.

[0021] The above scheme is adopted: through the design of the reverse threads in the adjusting member 1 2 and the adjusting member 2 10, the top blocks 34 in the two groups of support members 1 3 and the top blocks 34 in the two groups of support members 2 4 can be driven to move in the opposite or opposite directions along the directions of the adjusting member 1 2 and the adjusting member 2 10 respectively during rotation, so that the spacing between the support member 1 3, the support member 2 4 and the support member 3 5 can be flexibly adjusted, thereby being able to adapt to AMB substrates 6 of different sizes and shapes.

[0022] Reference Figures 7 to 9The clamping device 7 includes a clamping member 71 which is arranged on the inner side of the connecting frame 35 and is slidably connected to the connecting frame 35. A group of clamping members 71 are arranged on both sides of each group of adjusting support members 1 3, support members 2 4 and support members 3 5. One end of each group of clamping members 71 passes through the connecting frame 35 and is slidably connected to a mounting plate 72. The mounting plate 72 is U-shaped, and the bottom plate 31 passes through the mounting plate 72 and is slidably connected to the mounting plate 72. A straightening plate 73 for changing the state of the clamping member 71 is slidably inserted at the side end of the mounting plate 72. There are multiple groups of straightening plates 73, which are symmetrically distributed on both sides of the mounting plate 72. The straightening plates 73 are T-shaped, and the upper and lower surfaces of the contact ends with the clamping members 71 are inclined. A spring 74 is fixedly connected to the straightening plate 73, and one end of the spring 74 is connected to the mounting plate 72 is fixedly connected, two groups of springs 1 74 are provided, which are symmetrically distributed at the upper and lower ends of the straightening plate 73, and the clamping device 7 also includes a spring 2 75 fixedly connected to the top block 34, one end of the spring 2 75 is fixedly arranged with the clamping member 71, and two groups of springs 2 75 are symmetrically distributed between each group of top blocks 34 and each group of clamping members 71, and a group of telescopic rods 2 76 is respectively provided between the mounting plates 72 in each group of support members 1 3, support members 2 4 and support members 3 5, and the two ends of each group of telescopic rods 2 76 are respectively fixedly connected to a group of mounting plates 72, and a group of pull ropes 77 are clamped on the two symmetrical groups of telescopic rods 2 76, and a group of blocks are respectively fixedly connected at both ends of the pull ropes 77, and the blocks are respectively located on the outside of the two groups of telescopic rods 2 76 to prevent the pull ropes 77 from falling off, activating the straight plate and the pull ropes 7 in the plate 8. 7 is abutted, the pull rope 77 is an elastic rope, and the elastic limit of the pull rope 77 is greater than the elastic limit of the spring 2 75, so that the force generated by the spring 2 75 restoring its original length will not cause the pull rope 77 to deform, the clamping member 71 includes a slide plate 711 that penetrates the connecting frame 35 and is slidably connected to the connecting frame 35, the slide plate 711 is U-shaped, and a plug column 712 is penetrated and connected to the side end of the slide plate 711, and the plug column 712 is rotatably connected to the slide plate 711, one end of the plug column 712 is fixedly connected to a clamping plate 713, the clamping plate 713 is arranged on the inner side of the slide plate 711, and the other end of the plug column 712 is slidably connected to the inner side of the mounting plate 72, the plug column 712 is provided with two groups, symmetrically distributed on both sides of the clamping plate 713, one end of the clamping plate 713 is fixedly connected to a stop block 714, and the stop block 714 is circular, The top of the slide plate 711 is fixedly connected to a limit block 715, which is arranged on the side end of the clamping plate 713. The limit block 715 is triangular in shape, and the center of gravity of the circular abutment block 714 is biased toward one side of the limit block 715, so that the clamping plate 713 is initially inclined and abuts against the limit block 715. When the pull rope 77 is pressed down by the activation plate 8, the pull rope 77 gradually changes from a straight shape to a V shape. In this process, the pull rope 77 pulls the telescopic rod 2 76 on both sides, so that the adjustment support member 1 3, support member 2 4 and support member 3 5 on both sides move toward the AMB substrate 6. During the movement, the spring 2 75 is stretched by force until the clamping member 71 moves below the AMB substrate 6, and then during the downward movement, the connecting frame 35 slides downward in the mounting plate 72. During the sliding process,The connecting frame 35 abuts against the inclined surface on the straightening plate 73, so that the straightening plate 73 moves to the outside of the mounting plate 72 and the spring 1 74 is stretched. When the connecting frame 35 passes through the straightening plate 73, the straightening plate 73 is inserted into the mounting plate 72 again under the action of the spring 1 74. As the connecting frame 35 moves downward, the straightening plate 73 pushes the clamping plate 713 to rotate, changing from an inclined state to a vertical state. In this process, the abutment block 714 abuts against the side end of the AMB substrate 6. Under the elastic force of the spring 2 75 and the abutment force of the abutment block 714 and the AMB substrate 6, the pull rope 77 is deformed to fix the AMB substrate 6.

[0023] By adopting the above scheme: through the combination of the clamping member 71, the straightening plate 73 and the spring 74, the clamping force can be adjusted according to the AMB substrate 6 of different sizes to ensure that the clamping is stable and not too tight, thereby avoiding damage to the substrate. The operator only needs to press down the activation plate 8 to adjust the clamping force, which simplifies the operation process.

[0024] Reference Figure 10 to Figure 11 The limiting member 9 includes an outer cylinder 91 fixedly connected to the outer frame 1. The outer cylinder 91 is provided with four groups, which are symmetrically distributed at both ends of the outer frame 1. The top of the outer cylinder 91 passes through the activation plate 8 and is slidably connected to the activation plate 8. A group of rotating rods 92 are rotatably connected in each group of outer cylinders 91. The side ends of the rotating rods 92 are penetrated and connected with plug rods 93. The plug rods 93 are T-shaped. There are multiple groups of plug rods 93, which are evenly distributed on the side ends of the rotating rods 92, and the plug rods 93 are slidably connected to the rotating rods 92. The end faces of the plug rods 93 are fixedly connected with a block 94, which passes through the outer cylinder 91. The block 94 is one-eighth spherical, and its side ends have three faces, one of which is an arc face and two faces are straight faces. A spring three 95 is sleeved on the outside of the plug rods 93. One end of spring three 95 is fixedly connected to block 94, and the other end of spring three 95 is fixedly connected to rotating rod 92. During the downward movement of activation plate 8, activation plate 8 abuts against the arc surface of block 94, so that block 94 moves into outer tube 91 and contracts spring three 95, so that activation plate 8 passes through block 94. After passing through, activation plate 8 directly abuts against the bottom end of block 94, so that activation plate 8 is restricted in the current position. When metal brazing is completed, rotating rod 92 is rotated to make the arc surface on block 94 abut against outer tube 91 and retract into outer tube 91. At this time, activation plate 8 is no longer restricted by block 94, and under the action of spring two 75, V-shaped pull rope 77 is restored to a straight line.

[0025] The above scheme is adopted: by fixing the outer cylinder 91 on the outer frame 1 and the rotating rod 92 rotatably connected to the outer cylinder 91, as well as the design of the insertion rod 93 and the clamping block 94, the position of the activation plate 8 can be accurately limited to ensure that the activation plate 8 will not move accidentally during the clamping process, thereby ensuring the stability of the AMB substrate 6 during the clamping process, helping to maintain consistent operating conditions throughout the production process, thereby improving process consistency and product quality.

[0026] The working principle of the present invention is: when in use, first rotate the adjusting member 2 and the adjusting member 2 10 respectively, and under the action of the threaded rod 1 21 and the threaded rod 2 22 with opposite threads, the top blocks 34 on the two groups of support members 1 3 and the two groups of support members 2 4 move in opposite directions, and the spacing between the support members 1 3, the support members 2 4 and the support members 3 5 is enlarged, so that the placement table 36 on the support members 1 3, the support members 2 4 and the support members 3 5 can stably support the AMB substrate 6, and then press down the activation plate 8 to drive the placement table 36 to move downward, and the telescopic rod 1 32 is contracted. At the same time, the bottom end of the activation plate 8 synchronously presses down the pull rope 77, so that the pull rope 77 changes from a straight shape to a V shape. In this process, the pull rope 77 pulls the two sides. The telescopic rod 2 76, under the action of the telescopic rod 2 76, the adjustment support members 1 3, support members 2 4 and support members 3 5 on both sides move toward the AMB substrate 6. During the movement, the spring 2 75 is stretched by force until the clamping member 71 moves to the bottom of the AMB substrate 6. Then, during the downward movement, the connecting frame 35 slides downward in the mounting plate 72. During the sliding process, the connecting frame 35 abuts against the inclined surface on the straightening plate 73, so that the straightening plate 73 moves toward the outside of the mounting plate 72 and the spring 1 74 is stretched. After the connecting frame 35 passes through the straightening plate 73, under the action of the spring 1 74, the straightening plate 73 is inserted into the mounting plate 72 again, and as the connecting frame 35 moves downward, the straightening plate 73 pushes the clamping member 71. The plate 713 rotates from an inclined state to a vertical state. During this process, the abutment block 714 abuts against the side end of the AMB substrate 6. Under the elastic force of the spring 2 75 and the abutment force of the abutment block 714 and the AMB substrate 6, the pull rope 77 is deformed to fix the AMB substrate 6. In the downward movement process, the activation plate 8 abuts against the arc surface of the block 94, so that the block 94 moves into the outer tube 91, and the spring 3 95 contracts, so that the activation plate 8 passes through the block 94. After passing through, the activation plate 8 abuts against the bottom end of the block 94 directly, so that the activation plate 8 is restricted in the current position. At this time, the AMB substrate 6 is completely fixed in the fixture. When the metal brazing is completed, the rotating rod 92 is rotated to make the block 94 The arc surface on the outer cylinder 91 abuts against the outer cylinder 91 and retracts into the outer cylinder 91. At this time, the activation plate 8 is no longer restricted by the block 94, and under the action of the second spring 75, the V-shaped pull rope 77 is restored to a straight line. During the recovery process, the clamping member 71 moves to both sides to release the clamping of the AMB substrate 6. In the recovery process, the pull rope 77 pushes the activation plate 8 to move up and drives the connecting frame 35 to move up until the second spring 75 is restored to its original length. When the second spring 75 is restored to its original length, the AMB substrate 6 is driven to the top of the outer frame 1. At this time, the clamping plate 713 is no longer in contact with the straightening plate 73, and rotates under the action of gravity, so that the symmetrical clamping plate 713 is in an inverted eight-shaped shape, which is convenient for taking out the AMB substrate 6.Through the reverse threaded structure in adjusting member 1 2 and adjusting member 2 10, the operator can rotate these adjusting members to accurately adjust the spacing between support member 1 3, support member 2 4 and support member 3 5 to adapt to AMB substrates 6 of different sizes and shapes, thereby improving the flexibility and efficiency of production. In addition, this flexible spacing adjustment also helps to achieve more uniform heat distribution on substrates of different sizes, optimize heat conduction in the heating furnace, ensure the quality and consistency of the brazing process, and adapt to the thermal expansion characteristics of different substrates, thereby avoiding deformation of the substrate or thermal stress concentration caused by improper fixing methods. Through the combination of the clamping member 71, the straightening plate 73 and the spring 1 74 in the clamping device 7, the clamping force can be adjusted according to the AMB substrates 6 of different sizes to ensure stable clamping and avoid damage to the substrate. The sliding design of the clamping member 71 combined with the inclined surface of the straightening plate 73 and the elasticity of the spring 1 74 allows the operator to simply By pressing down the activation plate 8, the clamping force can be adjusted, which greatly simplifies the operation process, reduces the physical labor of the operator, and improves the production efficiency. This clamping design also ensures that the force of each substrate is evenly distributed during the clamping process, thereby improving the overall quality of the product. The limiting member 9 provides a precise position limit for the activation plate 8 to prevent it from accidentally moving during the clamping process, improves the safety and stability of the operation, ensures that the AMB substrate 6 can be kept in the optimal position during the brazing process, and avoids the potential risks caused by operating errors. In addition, this position limit helps to maintain consistent operating conditions throughout the production process, thereby improving the consistency of the process and the quality of the product. After the metal brazing is completed, the limit of the block 94 is released by rotating the rotating rod 92, so that the activation plate 8 and the clamping device 7 can quickly return to the initial state, which is convenient for smoothly removing the AMB substrate 6 and improving the efficiency of the entire process. ;
