Description

A copper-clad ceramic substrate carrier Technical Field

[0001] This utility model relates to the field of copper-clad ceramic substrate processing technology, specifically a copper-clad ceramic substrate carrier. Background Technology

[0002] Copper-clad ceramic substrates are a high-performance electronic packaging material widely used in high-power, high-temperature, and high-frequency electronic devices. They combine the excellent insulation and high thermal conductivity of ceramics with the high electrical conductivity of copper, making them suitable for power electronics, LEDs, aerospace, automotive electronics, and other fields. Commonly used materials include alumina, aluminum nitride, or silicon nitride, which provide insulation and mechanical support. Due to their superior heat dissipation and electrical performance, copper-clad ceramic substrates are becoming an irreplaceable key material for high-power-density electronic devices. Copper-clad ceramic substrate carriers are auxiliary tools or fixing devices used for manufacturing, processing, or testing copper-clad ceramic substrates. Their core function is to ensure the accurate positioning, protection, and efficient transfer of the substrate during the process.

[0003] In some existing copper-clad ceramic substrate carriers, when clamping the copper-clad ceramic substrate, the copper-clad ceramic substrate is placed on the upper end of the placement frame, and then a motor drives a bidirectional lead screw to rotate. The bidirectional lead screw drives the clamping plate to clamp the left and right ends of the copper-clad ceramic substrate.

[0004] Existing copper-clad ceramic substrate carriers of this type have the following problems: when clamping copper-clad ceramic substrates, they can only be clamped on the left and right sides or the front and back sides, which makes the copper-clad ceramic substrates prone to deviation, affecting the processing quality of the copper-clad ceramic substrates. Single-stage clamping can easily result in large-amplitude damage or insufficient clamping and unreliable clamping. To address these issues, we propose a copper-clad ceramic substrate carrier. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a copper-clad ceramic substrate carrier that can clamp the four sides of the copper-clad ceramic substrate when clamping it. It can clamp copper-clad ceramic substrates of different lengths and widths, avoid the copper-clad ceramic substrate from deviating, improve the processing quality of the copper-clad ceramic substrate, and effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a copper-clad ceramic substrate carrier, comprising a support platform, wherein a placement plate is provided at the upper middle part of the support platform and an mounting plate is provided at the lower end of the support platform, characterized in that: it further comprises a clamping mechanism;

[0007] Clamping mechanism: It includes a sliding groove, a sliding bar, a T-block, a support plate, a guide rod, and a clamping plate.

Guide rods are slidably connected to the sliding holes in the middle of the support plates. Clamping plates are fixedly connected between the inner ends of two longitudinally adjacent guide rods. When clamping the copper-clad ceramic substrate, the four sides of the copper-clad ceramic substrate can be clamped. Copper-clad ceramic substrates of different lengths and widths can be clamped to avoid deviation of the copper-clad ceramic substrate and improve the processing quality of the copper-clad ceramic substrate. The two-stage progressive clamping ensures a wide clamping range while avoiding the problems of aggressive clamping or insufficient progressive clamping.

Racks are respectively provided on the left side of the slip ring. The bottom wall of the support platform is rotatably connected to evenly distributed second gears via a rotating shaft. The upper side of the second gear is meshed with the adjacent racks. A circular groove is opened on the lower inner side of the support platform. A slip ring is rotatably connected inside the circular groove. An internal gear ring is provided on the inner side of the slip ring. The lower sides of the second gears are all meshed with the internal gear rings. The first gear is meshed with the internal gear rings, providing a rotatable connection.

[0010] Furthermore, the drive assembly one also includes a motor one, a worm gear and a worm wheel. The left end of the support platform is provided with a protective cover. The worm wheel is fixedly sleeved on the upper outer side of the rotating column. The motor one is located inside the protective cover. The right end of the output shaft of the motor one is fixedly connected to the worm gear. The worm gear meshes with the worm wheel. The input end of the motor one is electrically connected to the output end of the control switch group to provide clamping drive.

[0011] Furthermore, it also includes a second drive component, which includes a trapezoidal slider, rollers, U-shaped blocks, and support columns. The outer ends of the clamping plates are respectively fixedly connected to support columns, and the outer ends of the support columns are respectively fixedly connected to U-shaped blocks. The inside of the U-shaped blocks is rotatably connected to rollers. The trapezoidal sliders are respectively slidably connected to the inside of the T-shaped blocks, and the outer surfaces of the rollers are respectively slidably connected to the inclined surfaces of adjacent trapezoidal sliders to provide clamping drive.

[0012] Furthermore, the second drive assembly also includes springs. Springs are respectively fitted on the outside of the support column between the inner end of the U-shaped block and the inner wall of the adjacent T-shaped block to facilitate rebound.

[0013] Furthermore, the second drive assembly also includes a second motor and a lead screw. The second motor is respectively disposed at the front end of the T-block.

A protective cover 4 is provided at the left end of the support platform 2. The worm wheel 373 is fixedly sleeved on the upper outer side of the rotating column. The motor 371 is located inside the protective cover 4. The right end of the output shaft of the motor 371 is fixedly connected to the worm gear 372, which meshes with the worm wheel 373.

Each component is rotatably connected to a roller 384. Trapezoidal sliders 383 are slidably connected to the inside of the T-block 33. (The bottom surface of the trapezoidal slider 383 slides and limits the movement of the trapezoidal slider 383 against the bottom wall of the T-block 33 to prevent rotation of the trapezoidal slider 383 during linear motion. The outer surface of the support column 386 is slidably connected to the sliding opening of the side wall of the T-block 33.) The outer surface of the roller 384 is slidably connected to the inclined surface of the adjacent trapezoidal slider 383. The second drive assembly 38 also includes a spring 387. The spring 387 is sleeved on the outside of the support column 386 between the inner end of the U-block 385 and the inner wall of the adjacent T-block 33.

The middle part of lead screws 382 is threadedly connected to the threaded holes inside the adjacent trapezoidal sliders 383. The input ends of motor 2 381 are electrically connected to the output ends of control switch group 5. When processing the copper-clad ceramic substrate, the support platform 2 is first installed in the required position using mounting plate 1. Then, the copper-clad ceramic substrate is placed on the upper end of the placement plate 6. Then, by controlling the control switch group 5, motor 1 371 is operated. The output shaft of motor 1 371 drives worm gear 372 to rotate. The rotation of worm gear 372 drives the meshing worm wheel 373 to rotate. The rotation of worm wheel 373 drives the first gear 374 to rotate via a rotating column. The first gear 374 drives the slip ring 376 to rotate inside the circular groove 375 through the meshing internal gear ring 377. This drives the meshing second gear 378 to rotate. The rotation of second gear 378 drives the slip bar 32 to rotate in the groove 375 through the meshing rack 379. The internal mechanism 1 moves towards the center, which in turn moves the T-block 33 towards the center, thereby moving the clamping plate 36 closer to the copper-clad ceramic substrate. Then, by controlling the switch group 5, motor 381 operates. The output shaft of motor 381 drives the lead screw 382 to rotate, which in turn moves the trapezoidal slider 383 backward, causing its inclined surface to contact the outer surface of the roller 384. When the surface of the roller 384 contacts the highest point of the inclined surface of the trapezoidal slider 383, the clamping plate 36, supported by the sliding support of the guide rod 35, moves towards the center via the U-block 385 and support column 386, thus clamping the copper-clad ceramic substrate. After the copper-clad ceramic substrate processing is completed, motor 381 rotates counterclockwise, and its output shaft, via the lead screw 382, ​​moves the trapezoidal slider 383 forward, causing the clamping plate 36 to reset under the rebound of the U-block 385, support column 386, and spring 387.

[0023] The working principle of the copper-clad ceramic substrate carrier provided by this utility model is as follows: When processing the copper-clad ceramic substrate, the support platform 2 is first installed in the required position using the mounting plate 1. Then, the copper-clad ceramic substrate is placed on the upper end of the placement plate 6. Next, the motor 371 is activated by controlling the control switch group 5. The output shaft of the motor 371 drives the worm gear 372 to rotate. The rotation of the worm gear 372 drives the meshing worm wheel 373 to rotate. The rotation of the worm wheel 373 drives the first gear 374 to rotate via the rotating column. The first gear 374 drives the slip ring 376 to rotate inside the circular rotating groove 375 via the meshing internal gear ring 377. This, in turn, drives the meshing second gear 378 to rotate. The rotation of the second gear 378 drives the slip bar 32 to move towards the center inside the sliding groove 31 via the meshing rack 379. This, in turn, drives the T-block 33 to move towards the center. The clamping plate 36 will be moved closer to the copper-clad ceramic substrate. Then, by controlling the control switch group 5, the second motor 381 will operate. The output shaft of the second motor 381 will drive the lead screw 382 to rotate. The lead screw 382 will drive the trapezoidal slider 383 to move backward, so that the inclined surface of the trapezoidal slider 383 contacts the outer surface of the roller 384. When the surface of the roller 384 contacts the highest point of the inclined surface of the trapezoidal slider 383, the clamping plate 36 will move towards the center under the sliding support of the guide rod 35 through the U-shaped block 385 and the support column 386, thereby clamping the copper-clad ceramic substrate. After the copper-clad ceramic substrate is processed, the second motor 381 will operate counterclockwise. The output shaft of the second motor 381 will drive the trapezoidal slider 383 to move forward through the lead screw 382, ​​and then the clamping plate 36 will be reset under the rebound of the U-shaped block 385, the support column 386 and the spring 387.

[0024] It is worth noting that in the above embodiments, the motor 371 and the motor 381 disclosed can be either YJ61 or 35BYJ46. The control switch group 5 is provided with a switch button that corresponds one-to-one with the motor 371 and the motor 381 and is used to control their switching operation.
