Description

Technical Field

[0001] This invention relates to the field of substrate testing technology, specifically an automated SAT device for copper-clad ceramic substrates. Background Technology

[0002] When performing SAT testing on copper-clad ceramic substrates, the ultrasonic probe generates and emits ultrasonic pulses, which reach the workpiece under test through the coupling medium. Due to the difference in acoustic impedance, reflected echoes and transmitted waves are generated at the interface of various materials. The ultrasonic probe receives the reflected echoes and converts them into electrical signals. The computer processes the electrical signals and displays waveforms or images.

[0003] Manual loading and unloading are required, and manual review is needed after scanning the images. Moreover, the probe often results in inaccurate or incomplete detection results due to its single detection direction. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example: Figures 1-5 As shown, the present invention provides an automatic SAT equipment solution for copper-clad ceramic substrates, characterized in that: the automatic SAT equipment for copper-clad ceramic substrates includes a base plate 1, a detection platform 2 is mounted on the base plate 1, a first conveyor 3 is mounted on the detection platform 2, a stopper 4 is placed on the first conveyor 3, two mounting posts 5 are mounted on the base plate 1, the two mounting posts 5 are connected by a first module slide rail 6, a first slider 7 is slidably mounted on the first module slide rail 6, a second module slide rail 8 is mounted on the side of the first slider 7 near the detection platform 2, a second slider 9 is mounted on the second module slide rail 8, a first electric telescopic rod 10 is mounted at the end of the second slider 9, a probe 13 is mounted on the first electric telescopic rod 10, a data analysis and processing terminal 14 is mounted on the base plate 1, and the first module slide rail 6, the second module slide rail 8 and the probe 13 are all electrically connected to the data analysis and processing terminal 14.

[0037] The upper end of the first electric telescopic rod 10 is equipped with a detection seat 11, an electric ball joint 12 is rotatably mounted on the detection seat 11, and a probe head 13 is mounted on the electric ball joint 12.

[0038] When copper-clad ceramic substrates need to be inspected, a qualified standard template is input into the data analysis and processing terminal 14 before inspection. When the cartridge 4 is transported to the inspection position by the first conveyor 3, the data analysis and processing terminal 14 controls the first slider 7 to slide along the first module slide rail 6 and the second slider 9 to slide along the second module slide rail 8. The second slider 9 drives the probe head 13 to move synchronously through the inspection seat 11 and the electric ball joint 12, realizing the movement and inspection of the probe head 13 along the xy axis. The probe head 13 transmits the inspection results back to the data analysis and processing terminal 14. The inspection results are compared with the standard template in the data analysis and processing terminal 14 to complete the inspection. By directly comparing the results in the data analysis and processing terminal 14, the inspection results can be more accurate, reduce the workload of workers, and improve the inspection efficiency. At the same time, the electric ball joint 12 can rotate at a corresponding angle as the probe head 13 moves, realizing multi-angle inspection, which can make the inspection results more accurate and improve the inspection quality.

[0039] The base plate 1 is equipped with a pretreatment component 15 and a dewatering component 16. The operation of the pretreatment component 15 and the dewatering component 16 is driven by the sliding of the first slider 7.

[0040] like Figures 1-9 As shown, the pretreatment assembly 15 includes a pretreatment base 1501, a second conveyor 1502, a threaded block 1503, a first screw 1504, a mounting box 1505, a drive gear 1506, a driven gear 1507, a second screw 1508, a first guide rail 1509, a first slide 1510, a water inlet pipe 1511, and a water inlet valve 1512.

[0041] A pre-processing base 1501 is mounted on the base plate 1. A second conveyor 1502 is mounted on the pre-processing base 1501. Both the second conveyor 1502 and the first conveyor 3 are electrically connected to the data analysis and processing terminal 14. A threaded block 1503 is mounted on the first slider 7. A first screw 1504 is fitted onto the threaded block 1503. A mounting box 1505 is mounted on the pre-processing base 1501. A drive gear 1506 is rotatably mounted inside the mounting box 1505. The drive gear 1506 is connected to one end of the first screw 1504. The device is equipped with a driven gear 1507, which meshes with a drive gear 1506. A second screw 1508 is mounted on the driven gear 1507 and passes through the mounting box 1505. A first guide rail 1509 is mounted on the pretreatment base 1501. The first guide rail 1509 and the second screw 1508 are connected through a first slide block 1510. Several water inlet pipes 1511 are mounted on the first slide block 1510. Several water inlet valves 1512 are mounted below the first slide block 1510. The water inlet pipes 1511 are connected to the water inlet valves 1512.

[0042] Before testing the copper-clad ceramic substrate, a coupling agent needs to be added to its surface. Before testing, the worker places the workpiece-filled plug 4 on the second conveyor 1502. When the first slider 7 moves along the first module slide rail 6 away from the pre-processing base 1501, the first slider 7 drives the threaded block 1503 to move synchronously. The threaded block 1503 causes the first screw 1504 to rotate through the threaded engagement. The rotation of the first screw 1504 drives the drive gear 1506 to rotate synchronously. The drive gear 1506 drives the driven gear 15 through gear engagement. When the driven gear 1507 rotates, it drives the second screw 1508 to rotate. The second screw 1508 drives the first slide block 1510 to move along the first guide rail 1509 through the threaded engagement. When the first slide block 7 stops moving and the probe head 13 performs detection, the coupling agent flows into the workpiece in the stopper 4 through the water inlet pipe 1511 and the water inlet valve 1512, completing the coupling agent addition operation. This can avoid adding the coupling agent too early, which will affect the detection effect, and avoid adding too much or too little coupling agent manually, thereby improving the detection efficiency and detection effect.

[0043] The pretreatment assembly 15 also includes a mounting block 1513, a gear rail 1514, a gear hob 1515, a rotating shaft 1516, a roller 1517, a flexible puncture needle 1518, and a connecting rod 1519;

[0044] Two mounting blocks 1513 are symmetrically mounted on the pretreatment base 1501. The two mounting blocks 1513 are connected by a gear rail 1514. A gear hob 1515 is mounted on the gear rail 1514. A rotating shaft 1516 is coaxially mounted on the gear hob 1515. Several rollers 1517 are mounted on the rotating shaft 1516. Several flexible needles 1518 are mounted on the rollers 1517. The rotating shaft 1516 is connected to the first slide block 1510 through a connecting rod 1519. The rotating shaft 1516 and the connecting rod 1519 are rotatably connected.

[0045] When the first slide 1510 moves along the first guide rail 1509, the first slide 1510 drives the rotating shaft 1516 to move in the same direction through the connecting rod 1519. Due to the cooperation between the hobbing gear 1515 and the gear rail 1514, when the rotating shaft 1516 moves, the hobbing gear 1515 rotates under the restriction of the gear rail 1514. The rotation of the hobbing gear 1515 causes the rotating shaft 1516 to rotate synchronously. The rotation of the rotating shaft 1516 will drive the flexible puncture needle 1518 to rotate coaxially through the roller 1517. The flexible puncture needle 1518 will insert into the coupling agent on the workpiece and puncture the air bubbles in the coupling agent. Due to the large difference in acoustic impedance between the air bubble and the coupling agent, the ultrasonic waves will be scattered when they encounter the air bubble, resulting in energy loss and reduced signal strength, which seriously affects the accuracy of the detection. By puncturing the air bubble with the flexible puncture needle 1518, the detection accuracy of ultrasonic testing can be guaranteed.

[0046] When the flexible puncture needle 1518 is vertically downward, its end is inside the stopper 4. The distribution of the flexible puncture needle 1518 on the roller 1517 is divided into two parts. The arc length formed by the flexible puncture needle 1518 in each part is the same as the width of the workpiece frame on the stopper 4. The arc length between the two parts of the flexible puncture needle 1518 is the interval between each two workpiece frames.

[0047] Ensure that the flexible puncture needle 1518 can be accurately inserted into the area with the coupling agent, and prevent the flexible puncture needle 1518 from colliding with and scratching the other parts of the stopper 4 or the workpiece.

[0048] like Figures 1-4 As shown, the water removal assembly 16 includes a water removal base 1601, an inclined plate 1602, a drain hole 1603, and a drain outlet;

[0049] A water removal base 1601 is installed on the base plate 1. An inclined plate 1602 is installed on the water removal base 1601. Several drainage holes 1603 are opened on the inclined plate 1602. A drainage outlet 1604 is opened on the side of the water removal base 1601 away from the detection base 2.

[0050] After the test is completed, the data analysis and processing terminal 14 controls the first conveyor 3 to transport the tested plug 4 to the side near the dewatering base 1601. Since the inclined plate 1602 is installed at an angle, the plug 4 will tilt after entering the dewatering base 1601. The coupling water will be poured onto the inclined plate 1602 and discharged from the drain outlet 1604 and drain hole 1603. The plug 4 stays on the inclined plate 1602 to prevent the coupling agent from damaging the tested product, and at the same time facilitates the subsequent processing of the substrate.

[0051] The water removal assembly 16 also includes a third screw 1605, a second guide rail 1606, a second slide 1607, a distance sensor 1608, a second electric telescopic rod 1609, a jet nozzle 1610, a diverter pipe 1611, a heated air supply pipe 1612, an airbag chamber 1613, an airbag 1614, an intake pipe 1615, an exhaust pipe 1616, a pressure plate 1617, a push rod 1618, and a connecting frame 1619.

[0052] A third screw 1605 is rotatably mounted on the dewatering base 1601. The third screw 1605 is coaxially connected to the first screw 1504. A second guide rail 1606 is mounted on the dewatering base 1601. The third screw 1605 and the second guide rail 1606 are connected through a second slide block 1607. Several second electric telescopic rods 1609 are mounted below the second slide block 1607. Air nozzles 1610 are mounted at the ends of the second electric telescopic rods 1609. A diversion pipe 1611 is mounted above the second slide block 1607. The several air nozzles 1610 are connected through... The diversion pipe 1611 is connected to the base plate 1. An airbag chamber 1613 is installed on the base plate 1. An airbag 1614 is installed inside the airbag chamber 1613. A pressure plate 1617 is installed on one side of the airbag 1614. A push rod 1618 is installed on the pressure plate 1617. The push rod 1618 is connected to the threaded block 1503 through a connecting bracket 1619. An air intake pipe 1615 and an exhaust pipe 1616 are installed on the airbag 1614. Both the air intake pipe 1615 and the exhaust pipe 1616 are one-way pipes. The exhaust pipe 1616 is connected to the diversion pipe 1611 through a heated air supply pipe 1612.

[0053] When the first screw 1504 is driven to rotate by the first slider 7, the first screw 1504 will drive the third screw 1605 to rotate synchronously. The third screw 1605 drives the second slide 1607 to move along the second guide rail 1606 through the threaded engagement. The movement of the second slide 1607 drives the diversion pipe 1611 and the jet nozzle 1610 to move synchronously. At the same time, when the first slider 7 moves, it drives the pressure plate 1617 to compress the air bag 1614 through the connecting frame 1619 and the push rod 1618. The gas in the air bag 1614 is blown out from the exhaust pipe 1616, heated by the heating air supply pipe 1612, and finally sprayed out from the jet nozzle 1610 through the diversion pipe 1611. The gas blows off and dries the water droplets remaining on the stopper 4, improving the water removal effect.

[0054] The dewatering assembly 16 also includes a mounting plate 1620, a third electric telescopic rod 1621, a push plate 1622, and a product outlet 1623;

[0055] Two product outlets 1623 are symmetrically opened on the water-removing base 1601. An installation plate 1620 is installed on the base plate 1. A third electric telescopic rod 1621 is installed on the installation plate 1621. A push plate 1622 is installed at the end of the third electric telescopic rod 1621. The size of the push plate 1622 is smaller than the size of the product outlets 1623.

[0056] A distance sensor 1608 is installed on the second slide block 1607. The distance sensor 1608 is electrically connected to the second electric telescopic rod 1609 and the third electric telescopic rod 1621.

[0057] Distance sensor 1608 is used to detect the displacement length of the second slide 1607 and control the extension and retraction of the second electric telescopic rod 1609 according to the displacement length to ensure that the air nozzle 1610 and the plug 4 maintain a suitable blowing distance and improve the water removal effect. When the distance sensor 1608 detects that the water removal is completed, it will send an electrical signal to control the extension of the third electric telescopic rod 1621. The third electric telescopic rod 1621 pushes the dewatered plug 4 out of the product outlet through the push plate 1622 to make room for the next plug 4, which can improve the automation of the equipment and improve the detection efficiency.

[0058] Working principle of the invention:

[0059] When copper-clad ceramic substrates need to be inspected, a qualified standard template is input into the data analysis and processing terminal 14 before inspection. When the cartridge 4 is transported to the inspection position by the first conveyor 3, the data analysis and processing terminal 14 controls the first slider 7 to slide along the first module slide rail 6 and the second slider 9 to slide along the second module slide rail 8. The second slider 9 drives the probe head 13 to move synchronously through the inspection seat 11 and the electric ball joint 12, realizing the movement and inspection of the probe head 13 along the xy axis. The probe head 13 transmits the inspection results back to the data analysis and processing terminal 14. The inspection results are compared with the standard template in the data analysis and processing terminal 14 to complete the inspection. By directly comparing the results in the data analysis and processing terminal 14, the inspection results can be more accurate, reduce the workload of workers, and improve the inspection efficiency. At the same time, the electric ball joint 12 can rotate at a corresponding angle as the probe head 13 moves, realizing multi-angle inspection, which can make the inspection results more accurate and improve the inspection quality.

[0060] Before testing the copper-clad ceramic substrate, a coupling agent needs to be added to its surface. Before testing, the worker places the workpiece-filled plug 4 on the second conveyor 1502. When the first slider 7 moves along the first module slide rail 6 away from the pre-processing base 1501, the first slider 7 drives the threaded block 1503 to move synchronously. The threaded block 1503 causes the first screw 1504 to rotate through the threaded engagement. The rotation of the first screw 1504 drives the drive gear 1506 to rotate synchronously. The drive gear 1506 drives the driven gear 15 through gear engagement. When the driven gear 1507 rotates, it drives the second screw 1508 to rotate. The second screw 1508 drives the first slide block 1510 to move along the first guide rail 1509 through the threaded engagement. When the first slide block 7 stops moving and the probe head 13 performs detection, the coupling agent flows into the workpiece in the stopper 4 through the water inlet pipe 1511 and the water inlet valve 1512, completing the coupling agent addition operation. This can avoid adding the coupling agent too early, which will affect the detection effect, and avoid adding too much or too little coupling agent manually, thereby improving the detection efficiency and detection effect.

[0061] When the first slide 1510 moves along the first guide rail 1509, the first slide 1510 drives the rotating shaft 1516 to move in the same direction through the connecting rod 1519. Due to the cooperation between the hobbing gear 1515 and the gear rail 1514, when the rotating shaft 1516 moves, the hobbing gear 1515 rotates under the restriction of the gear rail 1514. The rotation of the hobbing gear 1515 causes the rotating shaft 1516 to rotate synchronously. The rotation of the rotating shaft 1516 will drive the flexible puncture needle 1518 to rotate coaxially through the roller 1517. The flexible puncture needle 1518 will insert into the coupling agent on the workpiece and puncture the air bubbles in the coupling agent. Due to the large difference in acoustic impedance between the air bubble and the coupling agent, the ultrasonic waves will be scattered when they encounter the air bubble, resulting in energy loss and reduced signal strength, which seriously affects the accuracy of the detection. By puncturing the air bubble with the flexible puncture needle 1518, the detection accuracy of ultrasonic testing can be guaranteed.

[0062] After the test is completed, the data analysis and processing terminal 14 controls the first conveyor 3 to transport the tested plug 4 to the side near the dewatering base 1601. Since the inclined plate 1602 is installed at an angle, the plug 4 will tilt after entering the dewatering base 1601. The coupling water will be poured onto the inclined plate 1602 and discharged from the drain outlet 1604 and drain hole 1603. The plug 4 stays on the inclined plate 1602 to prevent the coupling agent from damaging the tested product, and at the same time facilitates the subsequent processing of the substrate.

[0063] When the first screw 1504 is driven to rotate by the first slider 7, the first screw 1504 will drive the third screw 1605 to rotate synchronously. The third screw 1605 drives the second slide 1607 to move along the second guide rail 1606 through the threaded engagement. The movement of the second slide 1607 drives the diversion pipe 1611 and the jet nozzle 1610 to move synchronously. At the same time, when the first slider 7 moves, it drives the pressure plate 1617 to compress the air bag 1614 through the connecting frame 1619 and the push rod 1618. The gas in the air bag 1614 is blown out from the exhaust pipe 1616, heated by the heating air supply pipe 1612, and finally sprayed out from the jet nozzle 1610 through the diversion pipe 1611. The gas blows off and dries the water droplets remaining on the stopper 4, improving the water removal effect.

[0064] Distance sensor 1608 is used to detect the displacement length of the second slide 1607 and control the extension and retraction of the second electric telescopic rod 1609 according to the displacement length to ensure that the air nozzle 1610 and the plug 4 maintain a suitable blowing distance and improve the water removal effect. When the distance sensor 1608 detects that the water removal is completed, it will send an electrical signal to control the extension of the third electric telescopic rod 1621. The third electric telescopic rod 1621 pushes the dewatered plug 4 out of the product outlet through the push plate 1622 to make room for the next plug 4, which can improve the automation of the equipment and improve the detection efficiency.

[0065] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
