Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of automatic transportation of DCB ceramic substrates, and specifically relates to an automatic feeding device for DCB ceramic substrates. Background Art
[0002] In the field of modern electronic manufacturing, DCB (Direct Copper Bonded) ceramic substrates are widely used in many key industries such as power modules, automotive electronics, and aerospace due to their excellent electrical insulation performance, good thermal conductivity, and high mechanical strength. With the rapid development of related industries, higher requirements are put forward for the production efficiency and quality of DCB ceramic substrates. As a key link in the production process, the performance of the automatic feeding device directly affects the overall production efficiency.
[0003] Currently, there are various types of automatic feeding devices for DCB ceramic substrates on the market. A relatively common one is a device that uses a simple robotic arm for grasping and feeding. The robotic arm moves to the storage position to grasp the substrate through a preset program and then transfers it to the processing station. Another common automatic feeding device is a device that uses the principle of vacuum adsorption for material taking. It adsorbs the substrate by generating suction with a suction cup and then carries it.
[0004] However, when facing DCB ceramic substrates of different specifications, the flexibility of such devices is severely insufficient. Since the clamping structure of the robotic arm is often of a fixed size or has only limited adjustment methods, it is difficult to accurately adapt to substrates of various sizes. For substrates with large size deviations or special shapes, it is extremely easy to have unstable grasping and feeding failures. Moreover, in actual applications, when facing DCB ceramic substrates with uneven surfaces or small pores, the adsorption effect is greatly reduced, easily causing the substrate to fall during the handling process. In addition, such devices lack an effective adaptive adjustment mechanism when dealing with large-size substrates. Once the substrate tilts or warps due to factors such as gravity, it cannot automatically adjust the adsorption position or clamping force, making the feeding process extremely unstable and seriously affecting the continuity of production and product quality. Summary of the Invention

Specific embodiments
[0016] The technical solution of this patent will be further described in detail below in combination with specific embodiments.
[0017] As Figures 1-9 shown, the present invention provides a technical solution for an automatic feeding device for DCB ceramic substrates: It includes a workbench 1. On one side of the top of the workbench 1, there is a fixed support frame 2 fixedly connected. On the top of the fixed support frame 2, there is a driving mechanism 4. And a movable support frame 405 is slidably connected in the driving mechanism 4. At the bottom of the movable support frame 405, there is a second cylinder 406 fixedly connected. At the output end of the second cylinder 406, there is a movable frame 5 fixedly installed. A clamping mechanism 3 is arranged in the movable frame 5. The clamping mechanism 3 includes a first clamping rod 301 and a second clamping rod 303. In the movable frame 5, there is a third cylinder 502 fixedly connected. At the output end of the third cylinder 502, there is a connecting rod 17 fixedly connected. At the bottom of the connecting rod 17, there is a first clamping rod 301 rotatably connected. In the first clamping rod 301, there is a first electric telescopic rod 305 fixedly connected. At the output end of the first electric telescopic rod 305, there is a first extension rod 302 arranged. The first extension rod 302 is slidably connected with the first clamping rod 301. The first clamping rod 301 is located at the middle position above the second clamping rod 303. In the second clamping rod 303, there is a second electric telescopic rod 306 arranged. At the output end of the second electric telescopic rod 306, there is a second extension rod 304 fixedly connected. The second extension rod 304 is slidably connected with the second clamping rod 303. In the connecting rod 17, there is a first air storage tank 18 installed. In the movable frame 5, there is a second air storage tank 19 arranged. A second connecting pipe 20 is connected between the first air storage tank 18 and the second air storage tank 19. On both sides of the second air storage tank 19, there are movable rods 27 movably connected. One end of the movable rod 27 is fixedly connected with the inner side of the second clamping rod 303. On the top of the workbench 1, there is a material storage box 7 installed. In the material storage box 7, there are multiple groups of substrate bodies 15 stacked. In the connecting rod 17, there is a second connecting rod 22 slidably connected. At the top of the first clamping rod 301, there is a first connecting rod 21 rotatably connected. The first connecting rod 21 is rotatably connected with the second connecting rod 22. A tension spring 23 is fixedly connected between the connecting rod 17 and the first clamping rod 301; Specifically, when in use, first, the second cylinder 406 is used to push the movable frame 5 to descend into the storage box 7 towards the basic body 15. When the movable frame 5 descends to the specified position, through the mutual cooperation between the third air rod and the driving mechanism 4, the first clamping rod 301 and the second clamping rod 303 clamp the substrate body. If the size of the clamped substrate body 15 is relatively large, during the clamping process, due to factors such as its own gravity, one side of the substrate body 15 will turn downward, resulting in the part clamped by the first clamping rod 301 and the second clamping rod 303 being lifted upward. Since the first clamping rod 301 is rotatably connected to the connecting rod 17, the first clamping rod 301 will rotate upward around the rotation connection point with the connecting rod 17 as the substrate body 15 is lifted. During the upward rotation of the first clamping rod 301, the first connecting rod 21 rotatably connected to the top of the first clamping rod 301 also moves upward. The first connecting rod 21 cooperates with the second connecting rod 22 slidably connected inside the connecting rod 17. The upward movement of the first connecting rod 21 pushes the second connecting rod 22 to slide upward inside the connecting rod 17. The upward sliding of the second connecting rod 22 squeezes the first air storage barrel 18, causing the air pressure inside the first air storage barrel 18 to increase. The increased air pressure is squeezed into the second air storage barrel 19 through the second connecting pipe 20. Under the action of the air pressure, the movable rods 27 on both sides of the second air storage barrel 19 move outward. One end of the movable rod 27 is fixedly connected to the inner side of the second clamping rod 303, thereby pushing the second clamping rod 303 to open outward and increasing the distance between the second clamping rods 303. At the same time, the operator drives the first electric telescopic rod 305 inside the first clamping rod 301 and the second electric telescopic rod 306 inside the second clamping rod 303 to work according to the actual situation. The output end of the first electric telescopic rod 305 pushes the first extension rod 302 to slide outward along the inner slideway of the first clamping rod 301, and the output end of the second electric telescopic rod 306 pushes the second extension rod 304 to slide outward along the inner slideway of the second clamping rod 303, adjusting the extended lengths of the first extension rod 302 and the second extension rod 304 to better fit the edge of the large-size substrate body 15 and further stably clamp it. After completing the clamping of the substrate body 15 and the adjustment for the large-size substrate body 15, the driving mechanism 4 is started again, driving the movable support frame 405, the second cylinder 406, the movable frame 5, and the clamped substrate body 15 as a whole to move to the specified loading and unloading position. After reaching the specified position, through the conveying mechanism, corresponding loading and unloading operations are performed on the substrate body 15. When loading, the substrate body 15 is placed on the workbench 1 of the processing equipment;During blanking, the processed substrate body 15 is removed from the processing equipment and transported to a designated storage location. After the loading and unloading operation is completed, each component starts to reset. The driving mechanism 4 rotates in the reverse direction, driving the movable support frame 405, the second cylinder 406, the movable frame 5, etc. back to the initial position. The output end of the third cylinder 502 retracts, driving the connecting rod 17 to move upward, and the first clamping rod 301 also moves upward accordingly. The output ends of the first electric telescopic rod 305 and the second electric telescopic rod 306 retract, causing the first extension rod 302 and the second extension rod 304 to return to the first clamping rod 301 and the second clamping rod 303 respectively. At the same time, since the first clamping rod 301 moves upward, the positions of the first connecting rod 21 and the second connecting rod 22 return to the initial state, and the air pressures in the first air storage tank 18 and the second air storage tank 19 gradually balance. The movable rod 27 and the second clamping rod 303 also return to the initial position. Through the elastic potential energy of the tension spring 23, the pulling force on the first clamping rod 301 is always maintained, enabling the first clamping rod 301 to stably return to the initial position and always be in pressing contact with the substrate body 15. At this time, the equipment is reset and ready for the next clamping and loading / unloading operation of the substrate body 15. Through the mutual cooperation between the first clamping rod 301 and the second clamping rod 303, and between the first extension rod 302 and the second extension rod 304, the basic body 15 of different specifications can be fixed, greatly improving the reliability and stability of clamping. During the loading and unloading process, the substrate body 15 can be effectively prevented from shaking, shifting, or even falling, ensuring the accuracy and safety of the loading and unloading operation. Whether it is a small or large substrate body 15, the coordinated work of multiple clamping rods can provide sufficient clamping force to meet the loading and unloading requirements of substrate bodies 15 of various specifications. When facing a substrate body 15 with a larger size, the adaptive adjustment function of the equipment plays an important role. Through the coordinated work of components such as the first connecting rod 21, the second connecting rod 22, the first air storage tank 18, the second air storage tank 19, and the movable rod 27, the distance between the second clamping rods 303 can be automatically adjusted according to the warping condition of the substrate body 15. This adaptive adjustment function enables the equipment to quickly adapt to the clamping requirements of large-size substrate bodies 15 under different working conditions without manual intervention, not only improving work efficiency but also avoiding the problem of unstable clamping caused by inaccurate manual judgment, increasing the contact area between the clamping rods and the large-size substrate body 15, and further enhancing the clamping stability of the large-size substrate body 15, ensuring that the substrate body 15 always remains stable during the loading and unloading process and providing a reliable basis for subsequent processing operations; A fixing block 8 is fixedly installed on the back of the storage box 7. A first motor 9 is arranged at the top of the fixing block 8. The output end of the first motor 9 is fixedly connected with a first lead screw 16. A movable frame 10 is threadedly connected to the outside of the first lead screw 16. A suction block 11 is fixedly connected to the inside of the movable frame 10. A first connecting pipe 12 is arranged on the outside of the movable frame 10. And an air delivery pipe used in cooperation with the first connecting pipe 12 is installed in the movable frame 10. The air delivery pipe is connected and communicated with the suction block 11. A plurality of suction cups used in cooperation with the first connecting pipe 12 and the air delivery pipe are fixedly installed on the inside of the suction block 11. Slots used in cooperation with the suction block 11 are formed in both sides of the storage box 7. A discharging platform 14 is fixedly installed on the top of the workbench 1. A material conveying mechanism 6 is arranged on one side of the discharging platform 14. The material conveying mechanism 6 is fixed to the top of the workbench 1. A plurality of supporting legs 13 are fixedly connected to the bottom of the workbench 1. The bottom of the discharging platform 14 is of a hollow structure; Specifically, the output end of the first motor 9 drives the first lead screw 16 to rotate. Since the first lead screw 16 is threadedly connected with the movable frame 10, when the first lead screw 16 rotates, the movable frame 10 will move along the axial direction of the first lead screw 16. The suction block 11 inside the movable frame 10 moves accordingly and enters the inside of the storage box 7 through the slots on both sides of the storage box 7. During the movement, the operator can precisely adjust the position of the suction block 11 by controlling the rotation direction and speed of the first motor 9 so that it aligns with the substrate body 15 to be sucked. When the suction block 11 moves to the designated position, gas is extracted into the air delivery pipe through the first connecting pipe 12 to connect the air delivery pipe with the suction block 11. A plurality of suction cups inside the suction block 11 generate suction force under the action of the gas and adsorb the substrate body 15 on the suction cups. At this time, the suction block 11 and the substrate body 15 can be further moved upward by the first motor 9 to achieve the effect of raising the substrate body, so as to wait for cooperation with the subsequent clamping mechanism 3, enabling the clamping mechanism 3 to clamp and take out the substrate body 15 flexibly and stably; The driving mechanism 4 includes a first cylinder 401, a movable block 402, a second lead screw 403, and a second motor 404. The first cylinder 401 is fixed to both sides of the top of the fixed support frame 2 in a symmetric structure. The output end of the first cylinder 401 is fixedly connected to the movable block 402. The second motor 404 is fixed to the top of the movable block 402. The second lead screw 403 is located between the movable blocks 402, and the second lead screw 403 is fixedly connected to the output end of the second motor 404. A chute for the use of the movable block 402 is provided at the top of the fixed support frame 2. The second lead screw 403 penetrates through the movable support frame 405. The movable frame 5 includes an outer frame 501, a third cylinder 502, a slide rod 503, and a fixed frame 504. The slide rod 503 and the fixed frame 504 are both fixed to the inner side of the outer frame 501. The slide rod 503 movably penetrates through the second clamping rod 303. The second air storage barrel 19 is fixedly connected to the fixed frame 504. A convex block is fixedly connected to the end of the second connecting rod 22. An activity groove for the use of the convex block is provided on the outer side of the connecting rod 17. Rubber pads are provided on the inner surfaces of the first clamping rod 301 and the second clamping rod 303, and the inner surfaces of the first extension rod 302 and the second extension rod 304 are flush with the inner surfaces of the first clamping rod 301 and the second clamping rod 303 respectively. A spring 24 is fixedly connected between the first air storage barrel 18 and the second connecting rod 22. A first piston block 25 is movably connected inside the first air storage barrel 18. Second piston blocks 26 are movably connected inside the second air storage barrel 19 in a symmetric structure; Specifically, by starting the first cylinder 401, the output end thereof extends to push the movable block 402 to slide in the top chute of the fixed support frame 2. Since the first cylinders 401 are symmetrically arranged, the smooth movement of the movable block 402 can be ensured, thereby driving the second motor 404, the second lead screw 403 fixed on the top of the movable block 402, and the movable support frame 405 connected to the second lead screw 403 to move to a general position, initially adjusting the position of the clamping mechanism 3. Then, the second motor 404 is started, and its output end drives the second lead screw 403 to rotate. Since the second lead screw 403 passes through the movable support frame 405 and is threadedly connected, the movable support frame 405 can accurately move along the axial direction of the lead screw under the rotation of the second lead screw 403 until it moves directly above the target substrate body 15. Subsequently, the second motor 404 stops rotating, and the first cylinder 401 maintains the current state to keep the position stable, completing the positioning operation of the driving mechanism 4 for the clamping mechanism 3. The slide bar 503 provides stable guidance for the second clamping bar 303, ensuring the smooth up and down movement of the second clamping bar 303 during the clamping process and accurately expanding outward during the adaptive adjustment, enhancing the stability and reliability of the clamping mechanism 3. The second air storage barrel 19 is fixedly connected to the fixed frame 504, ensuring the structural stability during the air pressure adjustment, making the equipment operation more stable, and ensuring reliable execution during the adaptive adjustment of the distance between the second clamping bars 303. The rubber pads on the inner surfaces of the first clamping bar 301 and the second clamping bar 303 increase the friction force with the substrate body 15, effectively preventing the substrate body 15 from slipping during clamping, improving the clamping effect, and adapting to substrate bodies 15 with different surface materials. The spring 24 between the first air storage barrel 18 and the second connecting rod 22 plays a buffering role during the adaptive adjustment process, reducing the instantaneous impact force of the second connecting rod 22 on the first air storage barrel 18, protecting the equipment components, extending the service life of the equipment, and at the same time ensuring a smoother adaptive adjustment process and avoiding inaccurate adjustment caused by impact.
[0018] The working principle of the present invention is as follows: First, stack the substrate bodies 15 in the storage box 7, start the first motor 9, and drive the first lead screw 16 to rotate by its output end. Since the first lead screw 16 is threadedly connected to the movable frame 10, the movable frame 10 moves along the axial direction of the first lead screw 16, and the inner suction block 11 enters the box through the slots on both sides of the storage box 7. The operator precisely adjusts the position of the suction block 11 by controlling the rotation direction and speed of the first motor 9 so that it aligns with the substrate body 15. Secondly, after the suction block 11 reaches the designated position, the first connecting pipe 12 extracts gas from the air delivery pipe. The air delivery pipe is connected to the suction block 11, and multiple suction cups inside the suction block 11 generate suction force to adsorb the substrate body 15. Subsequently, the first motor 9 rotates in reverse, driving the suction block 11 and the substrate body 15 to move upward, waiting for the clamping mechanism 3. Once again, the first cylinders 401 on both sides of the top of the fixed support frame 2 are started, and the output ends are extended to push the movable block 402 to slide in the slide groove, driving the second motor 404, the second screw rod 403 and the movable support frame 405 to move to the approximate position. Then, the second motor 404 is started, and its output end drives the second screw rod 403 to rotate, so that the movable support frame 405 moves accurately along the screw rod axial direction to just above the target substrate body 15 to complete the positioning, and the second cylinder 406 pushes the movable frame 5 to descend toward the substrate body 15 in the storage box 7. After reaching the specified position, the third cylinder 502 is started, and its output end pushes the connecting rod 17 downward, driving the first clamping rod 301 downward to approach the substrate body 15, and the substrate body 15 is initially clamped by the mutual cooperation between the first clamping rod 301 and the second clamping rod 303, and the rubber pads on the inner surfaces of the first clamping rod 301 and the second clamping rod 303 increase the friction force to prevent the substrate body 15 from slipping; It is worth mentioning that if the substrate body 15 is large in size, one side will flip downward due to its own gravity and other factors during clamping, and the clamped part will tilt upward, and the first clamping rod 301 will rotate upward around the rotation point with the connecting rod 17, driving the first connecting rod 21 to move upward, and then pushing the second connecting rod 22 to slide upward in the connecting rod 17, and the second connecting rod 22 squeezes the first piston block 25 in the first gas storage barrel 18 to increase the air pressure, and the gas enters the second gas storage barrel 19 through the second connecting pipe 20. The air pressure in the second gas storage barrel 19 pushes the second piston block 26 to move to both sides, driving the movable rod 27 to move outward, pushing the second clamping rod 303 to open outward to increase the spacing, and at the same time, the operator controls the first electric telescopic rod 305 and the second electric telescopic rod 306 to extend the first extension rod 302 and the second extension rod 304 to fit the edge of the large-sized substrate body 15 for stable clamping. In this process, the spring 24 between the first gas storage barrel 18 and the second connecting rod 22 plays a buffering role, protects equipment components, and ensures smooth adjustment. Finally, the driving mechanism 4 drives the movable support frame 405, the second cylinder 406, the movable frame 5 and the clamped substrate body 15 to move to the designated loading and unloading positions, and performs loading and unloading operations through the conveying mechanism. When loading, the substrate body 15 is placed on the workbench 1 of the processing equipment, and when unloading, the processed substrate body 15 is removed from the processing equipment and transported to the designated storage position. After loading and unloading are completed, the driving mechanism 4 operates in the opposite direction to drive each component back to the initial position, and the output end of the third cylinder 502 retracts, driving the connecting rod 17 upward, and the first clamping rod 301 moves upward accordingly, and the output ends of the first electric telescopic rod 305 and the second electric telescopic rod 306 retract, so that the first extension rod 302 and the second extension rod 304 return to their original positions, and the first connecting rod 21 and the second connecting rod 22 return to their initial positions. The air pressure in the first gas storage barrel 18 and the second gas storage barrel 19 is balanced, and the movable rod 27 and the second clamping rod 303 return to their initial positions. The tension spring 23 maintains the tension on the first clamping rod 301, so that the first clamping rod 301 stably returns to the initial position, and the equipment is ready for the next operation.
