Description

Technical Field

[0001] This invention relates to the field of curved surface inspection equipment technology, specifically to a curved surface inspection device for copper base plates. Background Technology

[0002] As a crucial component in semiconductor products, the copper heat sink is responsible for transferring heat generated by the internal chip during operation. This heat is then dissipated through heat dissipation channels to the outer surface of the copper heat sink and finally to the heatsink via thermal grease. However, the planar structure of the copper heat sink can generate stress during soldering and installation, causing the ends to bend upwards and the base plate to become concave. This leads to poor contact between the copper heat sink and the thermal grease, severely reducing thermal conductivity and significantly impacting the lifespan of the equipment. Therefore, a pre-bending process is necessary. All four edges of the copper heat sink need to be pre-bent to counteract the stress generated during soldering and installation, ensuring that the copper heat sink remains flat after installation.

[0003] For the heat dissipation copper base plate that meets the above technical requirements, the curved surface of the heat dissipation copper base plate needs to be inspected during the production and processing process to ensure that the curved surface structure of the heat dissipation copper base plate meets the design requirements. The existing surface inspection equipment for heat dissipation copper base plates generally involves placing the heat dissipation copper base plate on the inspection station for inspection, then flipping the heat dissipation copper base plate for inspection. After the inspection is completed, the heat dissipation copper base plate is removed and a new heat dissipation copper base plate is installed for inspection. The inspection efficiency is low, and the manual loading makes it impossible to guarantee the accuracy of the inspection.

[0004] For example, the aforementioned problem exists in patent (CN220613925U); it describes "a heat-dissipating copper base surface inspection device, including an inspection platform and a moving component. The inspection platform has support columns 1 on both the left and right sides at its lower end, and support columns 2 penetrate through the lower ends of the support columns 1. The moving component is located inside the support columns 2, and includes a motor 1, a threaded rod 1, a slider 1, and wheels. The lower end of the motor 1 has a threaded rod 1." Compared with existing heat-dissipating copper base surface inspection devices, this heat-dissipating copper base surface inspection device uses wheels extending from support columns 2, making it easier for operators to push the device and saving time and effort when moving it. The wheels retract into support columns 2, allowing the device to move more smoothly and efficiently. The device is designed to fit snugly against the ground, ensuring stability. Motor 3 rotates clamping rods 1 and 2, flipping the copper heat sink to the other side. Inspectors then inspect the other side of the copper heat sink, facilitating this flipping inspection. However, the copper heat sink surface inspection device in the aforementioned patent requires placing the copper heat sink on the inspection station, flipping it over, removing it, and then installing a new one. This process is inefficient, and manual loading compromises the accuracy of the inspection.

[0005] To address the issues of existing surface inspection devices for heat dissipation copper base plates, which typically involve placing the copper base plate on the inspection station for inspection, then flipping it over for inspection, removing the old base plate, and then installing a new one for inspection, we propose a curved surface inspection device for copper base plates.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a curved surface inspection device for copper base plates, comprising an inspection frame, a loading frame, a unloading frame, and a multi-axis robot, wherein the loading frame and the unloading frame are respectively disposed on both sides of the inspection frame, and the multi-axis robot is disposed between the loading frame and the unloading frame; the inspection frame includes a height detector and a rotatably disposed tooling plate, wherein the height detector is disposed above one side of the tooling plate, and the top of the tooling plate is provided with a plurality of rotatably connected support plates, and the top of the support plates is provided with a horizontally disposed placement frame; the inspection frame further includes a first rotation drive mechanism for the tooling plate and a second rotation drive mechanism for the support plates.

[0008] Furthermore, the top of the placement rack is provided with a placement groove, and the top of the placement groove and the end of the placement groove away from the center of the tooling tray are both open. Guide clamping components are symmetrically provided on both sides of the inner wall of the placement groove.

[0009] Furthermore, the guiding and clamping assembly includes two guiding wheels and several clamping wheels. The two guiding wheels are rotatably disposed at both ends of the placement groove, and the clamping wheels are rotatably disposed between the two guiding wheels.

[0010] Furthermore, the guide wheel includes a first support plate and a first support shaft. The first support shaft is vertically rotatably disposed at the bottom center of the first support plate. The first support plate is fixedly connected to the inner wall of the placement groove. The first support wheel is sleeved on the outer wall of the first support shaft. An annular guide groove is provided at the center of the outer wall of the first support wheel.

[0011] Furthermore, the cross-section of the annular guide groove has a semi-circular groove structure on both sides.

[0012] Furthermore, the clamping wheel includes a second support plate and a second support shaft. The second support shaft rotates vertically to the center of the bottom of the second support plate. The second support plate is fixedly connected to the inner wall of the placement groove. The second support wheel is sleeved on the outer wall of the second support shaft. The outer wall of the second support wheel is provided with a flexible clamping pad. The outer wall of the flexible clamping pad is vertically provided with a plurality of clamping strips. The outer wall of the flexible clamping pad is provided with an arc-shaped groove between two adjacent clamping strips.

[0013] Furthermore, the second rotary drive mechanism includes a rack and several gears, the gears meshing with the rack, a support frame vertically mounted at the bottom of the support plate, the gears fixedly sleeved on the bottom of the outer wall of the support frame, and the rack positioned below the height detector.

[0014] Furthermore, the second rotary drive mechanism also includes a first linear drive component and a second linear drive component arranged horizontally, the first linear drive component and the second linear drive component being perpendicular to each other, and the first linear drive component and the second linear drive component being connected to a rack and pinion drive.

[0015] Furthermore, a first guide rail is horizontally provided on one side of the outer wall of the rack, and a second guide rail is provided on the other side of the outer wall of the rack. A first slider that slides and matches the first guide rail is horizontally provided at the output end of the first linear drive component, and a second slider that slides and matches the second guide rail is horizontally provided at the output end of the second linear drive component.

[0016] Furthermore, the first guide rail and the second guide rail are perpendicular to each other, the first guide rail is perpendicular to the first linear drive component, and the second guide rail is perpendicular to the second linear drive component.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. This invention, through the setting of a detection frame, a height detector, a tooling tray, a support tray, a placement rack, and a second rotary drive mechanism, allows the height detector to directly detect the height of the heat-dissipating copper base plate on the tooling tray. The placement rack provides a placement position for the heat-dissipating copper base plate. The support tray and placement rack on the tooling tray rotate circumferentially with the tooling tray, causing the heat-dissipating copper base plate on the placement rack to adjust its circumferential movement. This enables the switching of circumferential displacement of the heat-dissipating copper base plate at different positions, allowing for non-stop switching of the heat-dissipating copper base plate below the height detector. This effectively improves the efficiency of arc surface detection of the heat-dissipating copper base plate. Furthermore, this invention eliminates the need for manual loading, effectively ensuring the accuracy of arc surface detection. The arc surface detection of the heat-dissipating copper base plate in this invention involves detecting the surface height of the heat-dissipating copper base plate. Height parameters at different locations on the surface of the heat dissipation copper base plate are collected and compared with standard data. The second rotary drive mechanism can rotate the support plate, and the placement frame rotates with the support plate, enabling the switching of the rotation position of the heat dissipation copper base plate during height detection. This allows for arc surface detection of the heat dissipation copper base plate from multiple different angles, effectively ensuring the arc surface detection of the four sides of the heat dissipation copper base plate and improving the efficiency and accuracy of arc surface detection. Two guide wheels in the guide clamping assembly provide rolling guidance and support for the heat dissipation copper base plate at both ends of the placement slot, while multiple clamping wheels clamp and support the heat dissipation copper base plate between the two guide wheels, ensuring rapid loading and unloading of the heat dissipation copper base plate, while also ensuring the stability of the heat dissipation copper base plate during station switching and rotation adjustment.

[0018] 2. This invention, by setting a second rotary drive mechanism including a rack, a first linear drive assembly, a second linear drive assembly, and several gears, allows the rack in the second rotary drive mechanism to drive the gears to rotate. The first and second linear drive assemblies can respectively drive the rack to perform horizontal linear motion adjustment in two vertical directions, enabling the rack to approach and move away from the gear located below the height detector. Simultaneously, the linear motion adjustment of the rack can drive the gear located below the height detector to perform rotational motion adjustment, thereby driving the heat dissipation copper base plate to perform rotational motion adjustment. When the rack approaches the gear and... After the gears mesh, the linear motion adjustment of the second linear drive component can be achieved by the rack driving the gear to rotate, thereby driving the heat dissipation copper base plate to rotate. When the rack moves away from the gear, the rack disengages from the gear. At this time, the rack will not hinder the circumferential motion of the gear, allowing the gear under the heat dissipation copper base plate after the test to move normally from the test station and allowing the gear under the next heat dissipation copper base plate to enter the test station normally. This ensures that the support plate and the placement rack can move normally in a circular motion, and ensures the normal operation of the heat dissipation copper base plate circular motion switching station.

[0020] 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. Example 1

[0021] Please see Figures 1-6 This invention provides a technical solution: a curved surface inspection device for copper base plates, comprising an inspection frame 1, a loading frame 2, a unloading frame 3, and a multi-axis robot 4. The loading frame 2 and the unloading frame 3 are respectively located on both sides of the inspection frame 1, and the multi-axis robot 4 is located between the loading frame 2 and the unloading frame 3. The inspection frame 1 includes a height detector 101 and a rotatably mounted tooling plate 102. The height detector 101 is located above one side of the tooling plate 102, and the top of the tooling plate 102 is provided with a plurality of rotatably connected support plates 103. A horizontally mounted placement frame 5 is provided on the top of the support plate 103. The inspection frame 1 also includes a first rotary drive mechanism for the tooling plate 102 and a second rotary drive mechanism 6 for the support plate 103. A placement groove 501 is provided on the top of the placement groove 501. The top of the placement groove 501 and one end of the placement groove 501 away from the center of the tooling plate 102 are both open. Guide clamping assemblies are symmetrically arranged on both sides of the inner wall of the placement groove 501. The guide clamping assembly includes two guide wheels 503 and several clamping wheels 502. The two guide wheels 503 are respectively... The clamping wheel 502 is rotatably disposed between two guide wheels 503 and rotatably disposed at both ends of the placement groove 501. Each guide wheel 503 includes a first support plate 504 and a first support shaft 505. The first support shaft 505 is vertically rotatably disposed at the bottom center of the first support plate 504. The first support plate 504 is fixedly connected to the inner wall of the placement groove 501. A first support wheel 506 is sleeved on the outer wall of the first support shaft 505. An annular guide groove 507 is provided at the center of the outer wall of the first support wheel 506. The clamping wheel 502 includes a first... The second support plate 508 and the second support shaft 509 are vertically rotated to the center of the bottom of the second support plate 508. The second support plate 508 is fixedly connected to the inner wall of the placement groove 501. The outer wall of the second support shaft 509 is fitted with a second support wheel 510. The outer wall of the second support wheel 510 is provided with a flexible clamping pad 511. The outer wall of the flexible clamping pad 511 is vertically provided with a plurality of clamping strips 512. The outer wall of the flexible clamping pad 511 is provided with an arc-shaped groove 513 between two adjacent clamping strips 512.

[0022] In one embodiment, the cross-section of the annular guide groove 507 has a semi-circular groove structure on both sides. Through the above-mentioned structural limitation, the annular guide groove 507 contacts the heat dissipation copper base plate with a semi-circular groove structure, ensuring that the semi-circular groove structure of the annular guide groove 507 can better adapt to the arc surface structure of the heat dissipation copper base plate, so that the heat dissipation copper base plate can be better inserted into the inside of the guide clamping assembly of the placement groove 501, and the heat dissipation copper base plate can be better pulled out from the inside of the guide clamping assembly of the placement groove 501.

[0023] Working principle of the invention: Refer to the instruction manual appendix Figures 1-6 This invention comprises a testing frame 1, a loading frame 2, a unloading frame 3, a multi-axis robot 4, a height detector 101, a tooling tray 102, a support tray 103, a placement frame 5, and a second rotary drive mechanism 6. The testing frame 1 provides a testing position for the heat-dissipating copper base plate. The loading frame 2 is used for loading and conveying the heat-dissipating copper base plate. The unloading tray 3 is used for unloading the heat-dissipating copper base plate. The multi-axis robot 4 is used for loading and unloading the heat-dissipating copper base plate on the testing frame 1. The height detector 101 directly detects the height of the heat-dissipating copper base plate on the tooling tray 102, which provides a testing fixture. The support tray 103 supports the placement frame 5 on the tooling tray 102, providing a placement position for the heat-dissipating copper base plate. The first rotary drive mechanism drives the tooling tray 102 to rotate. The support tray 103 and the placement frame 5 on the tooling tray 102 rotate circumferentially with the tooling tray 102, allowing the heat-dissipating copper base plate on the placement frame 5 to rotate. The copper base plate undergoes circumferential motion adjustment, thereby enabling circumferential displacement switching of the heat dissipation copper base plate at different workstations. This allows for non-stop switching of the heat dissipation copper base plate below the height detector 101, effectively improving the efficiency of arc surface detection of the heat dissipation copper base plate. Furthermore, this invention eliminates the need for manual loading, ensuring the accuracy of arc surface detection. The second rotary drive mechanism 6 rotates the support disk 103, adjusting its rotation only for the support disk 103 located below the height detector 101. The placement frame 5 rotates along with the support disk 103, allowing the heat dissipation copper base plate below the height detector 101 to rotate. This enables position switching of the heat dissipation copper base plate during height detection, allowing for arc surface detection from multiple different angles. This effectively ensures the arc surface detection of all four sides of the heat dissipation copper base plate, significantly improving the efficiency and accuracy of arc surface detection. The placement slot 501 at the top of the placement rack 5 provides a placement space for the heat dissipation copper base plate. The opening arrangement of the placement slot 501 ensures rapid loading and unloading of the heat dissipation copper base plate, and at the same time facilitates the height detector 101 to directly collect height data from the surface of the heat dissipation copper base plate from above the placement slot 501. The guide clamping assembly guides and clamps the heat dissipation copper base plate on both sides inside the placement slot 501, which can effectively ensure rapid loading and unloading of the heat dissipation copper base plate, while ensuring the stability of the heat dissipation copper base plate during the height detection process. The two guide wheels 503 in the guide clamping assembly roll and guide the heat dissipation copper base plate at both ends of the inner side of the placement groove 501, and multiple clamping wheels 502 clamp and support the heat dissipation copper base plate between the two guide wheels 503, ensuring the rapid loading and unloading operation of the heat dissipation copper base plate, while ensuring the stability of the heat dissipation copper base plate during the switching of work positions and the adjustment of its rotational movement. The first support plate 504 in the guide wheel 503 provides overhead support for the first support shaft 505, and the first support shaft 505 provides rotational support for the first support wheel 506. The annular guide groove 507 forms a concave structure on the outer wall of the first support wheel 506. When the multi-axis robot 4 places the heat dissipation copper base plate into the placement groove 501, the heat dissipation copper base plate is inserted horizontally between the two guide wheels 503 at one end of the placement groove 501. The heat dissipation copper base plate passes through the concave structure between the two guide wheels 503, and both sides of the heat dissipation copper base plate contact the concave structure of the guide wheel 503. During the process of inserting the heat dissipation copper base plate into the placement groove 501, the heat dissipation copper base plate rolls and is guided by the concave structure of the guide wheel 503. The concave structure of the outer wall of the guide wheel 503 can better adapt to the arc structure of the heat dissipation copper base plate. The second support plate 508 in the clamping wheel 502 provides overhead support for the second support shaft 509, and the second support shaft 509 provides rotational support for the second support wheel 510. The flexible clamping pad 511 provides flexible support on the outer wall of the second support wheel 510. The clamping strips 512 form multiple strip-shaped clamping contact surfaces on the outer wall of the flexible clamping pad 511. The arc-shaped grooves 513 provide arc-shaped isolation support between adjacent clamping strips 512, ensuring that the clamping strips 512 can flexibly buffer deformation while also ensuring that the clamping strips 512 have sufficient flexible support and rebound force. When the heat dissipation copper base plate enters the clamping wheels 502 on both sides... When the heat dissipation copper base plate is between 2 and 3, the two sides of the heat dissipation copper base plate contact and support the clamping strips 512 on the outer wall of the flexible clamping pad 511. The heat dissipation copper base plate is squeezed and deformed by the clamping strips 512, and the clamping strips 512 clamp and support the heat dissipation copper base plate. As the heat dissipation copper base plate continues to be inserted into the inner side of the placement groove 501, the heat dissipation copper base plate drives the clamping wheel 502 to roll and contact guide through the clamping strips 512, so that the clamping wheel 502 can roll and clamp and guide the heat dissipation copper base plate, ensuring the rapid loading and unloading operation of the heat dissipation copper base plate, while ensuring the stability of the heat dissipation copper base plate during the switching of work positions and the adjustment of the self-rotation movement. The arc surface detection of the heat dissipation copper base plate in this invention involves measuring the surface height of the heat dissipation copper base plate. By collecting and comparing the height parameters at different locations on the surface of the heat dissipation copper base plate with reference standard data, multi-point data acquisition and processing can be performed simultaneously on the arc surface structure of the heat dissipation copper base plate. The height data and height difference data at these points can be collected and analyzed. Then, the heat dissipation copper base plate is rotated and adjusted, and multi-point data acquisition and processing is performed again on other locations on the heat dissipation copper base plate. At the same time, multi-point height data and height difference data at these locations are collected and analyzed. After at least two multi-point height data and height difference data collection and analysis, the surface data of the heat dissipation copper base plate obtained from the collection and analysis is compared and analyzed with the reference standard data to determine whether the surface data of the heat dissipation copper base plate meets the requirements for arc surface data. In addition, the arc surface detection work in this invention does not require flipping the heat dissipation copper base plate. The height detector 101 can use an existing multi-point laser rangefinder. The device integrates multiple independent laser rangefinder sensors, which are synchronously arranged according to the layout of the points to be measured. During measurement, all sensors simultaneously emit lasers to the corresponding detection points. Each laser is reflected by the target and received by the corresponding sensor. The time difference pulse method of laser emission and reception is calculated, or the phase difference phase method of emitted light and reflected light is detected, and the distance from each point to the sensor is independently calculated. The processor combines the device reference plane and finally synchronously outputs the height data of all points. It can also automatically calculate derived parameters such as flatness, warpage, and height difference. The first rotary drive mechanism, height detector 101, loading rack 2, unloading rack 3, and multi-axis robot 4 all adopt existing mature structures. Their transmission principle, lubrication structure, and control method can all adopt existing mature conventional structural components and conventional control technology. The above content is common knowledge in the field and is not an improvement of the present invention. Therefore, it has not been explained in detail. Example 2

[0024] Please see Figures 1-3 and Figures 7-10 The present invention provides a technical solution: a curved surface detection device for a copper base plate, wherein the second rotary drive mechanism 6 includes a rack 601 and a plurality of gears 602, the gears 602 meshing with the rack 601, a support frame 104 vertically provided at the bottom of the support disk 103, the gears 602 being fixedly sleeved on the bottom of the outer wall of the support frame 104, and the rack 601 being located below the height detector 101; the second rotary drive mechanism 6 further includes a horizontally arranged first linear drive assembly 603 and a second linear drive assembly 604, the first linear drive assembly... The moving component 603 and the second linear drive component 604 are perpendicular to each other. The first linear drive component 603 and the second linear drive component 604 are connected to the rack 601 in a transmission manner. A first guide rail 605 is horizontally provided on one side of the outer wall of the rack 601, and a second guide rail 606 is provided on the other side of the outer wall of the rack 601. A first slider 607 that slides and matches the first guide rail 605 is horizontally provided at the output end of the first linear drive component 603, and a second slider 608 that slides and matches the second guide rail 606 is horizontally provided at the output end of the second linear drive component 604.

[0025] In one embodiment, the first guide rail 605 and the second guide rail 606 are perpendicular to each other, the first guide rail 605 is perpendicular to the first linear drive component 603, and the second guide rail 606 is perpendicular to the second linear drive component 604. The first guide rail 605 and the second guide rail 606 are designed to be perpendicular to each other so that the first guide rail 605 and the second guide rail 606 respectively guide and support the linear motion of the first linear drive component 603 and the second linear drive component 604, ensuring the stability of the movement adjustment of the rack 601 by the first linear drive component 603 and the second linear drive component 604.

[0026] Working principle of the invention: Refer to the attached diagram in the instruction manual. Figures 1-3 and Figures 7-10The present invention provides a second rotary drive mechanism 6, which includes a rack 601, a first linear drive assembly 603, a second linear drive assembly 604, and several gears 602. The rack 601 in the second rotary drive mechanism 6 drives the gears 602 to rotate. The first linear drive assembly 603 and the second linear drive assembly 604 can respectively drive the rack 601 to perform horizontal linear motion adjustment in two vertical directions, so that the rack 601 can move closer to and further away from the gears 602 located below the height detector 101. At the same time, it ensures that the linear motion adjustment of the rack 601 can drive the gears 602 located below the height detector 101 to perform rotational motion adjustment. Then, the support frame 104 drives the support plate 103 and the placement frame 5 to perform rotational motion adjustment, thereby driving the heat dissipation copper base plate to perform rotational motion adjustment. The linear motion adjustment of the first linear drive assembly 603 can drive the rack 601 to move closer to or away from the gear 602. When the rack 601 moves closer to and meshes with the gear 602, the linear motion adjustment of the second linear drive assembly 604 can drive the rack 601 to perform linear motion. The rack 601 drives the gear 602 to perform rotational motion adjustment, which in turn drives the support plate 103 and the placement frame 5 to perform rotational motion adjustment through the support frame 104, thereby driving the heat dissipation copper base plate to perform rotational motion adjustment. When the rack 601 moves away from the gear 602... During the movement, rack 601 disengages from gear 602. At this time, rack 601 will not hinder the circumferential movement of gear 602, allowing gear 602 under the heat dissipation copper base plate after the test to move normally away from the test station and allowing gear 602 under the next heat dissipation copper base plate to enter the test station normally. This ensures that support plate 103 and placement rack 5 can move normally in a circular motion and ensures the normal operation of the heat dissipation copper base plate circular motion switching station. This is also the main reason why the rotary drive device with direct contact connection is not used in this invention. The sliding engagement of the first guide rail 605 and the first slider 607 can provide sliding guidance and support for the rack 601 during the telescopic movement of the second linear drive assembly 604, which can effectively ensure the movement stability of the rack 601; the sliding engagement of the second guide rail 606 and the second slider 608 can provide sliding guidance and support for the rack 601 during the telescopic movement of the first linear drive assembly 603, which can effectively ensure the movement stability of the rack 601. When the first linear drive assembly 603 extends or retracts, the second guide rail 606 on the outer wall of the rack 601 slides along the second slider 608 at the output end of the second linear drive assembly 604. At this time, the second slider 608 does not move, and the first guide rail 605 and the first slider 607 move synchronously with the rack 601. There is no relative displacement between the first guide rail 605, the first slider 607, and the rack 601. When the second linear drive assembly 604 extends or retracts, the first guide rail 605 on the outer wall of the rack 601 slides along the first slider 607 at the output end of the first linear drive assembly 603. At this time, the first slider 607 does not move, and the second guide rail 606 and the second slider 608 move synchronously with the rack 601. There is no relative displacement between the second guide rail 606, the second slider 608, and the rack 601. Through the above design, the motion guidance and support of the rack 601 can be effectively achieved, effectively ensuring the safety and stability of the rack 601's motion adjustment. The first linear drive assembly 603 and the second linear drive assembly 604 can be either a cylinder or a servo electric cylinder. The first linear drive assembly 603 and the second linear drive assembly 604 are both fixedly arranged under the table of the detection frame 1. Their conventional accessories and control methods can all adopt conventional existing mature designs. The rack 601, gear 602, first linear drive assembly 603, second linear drive assembly 604, first guide rail 605, second guide rail 606, first slider 607, and second slider 608 all adopt existing mature structures. Their transmission principle, lubrication structure, and control method can all adopt existing mature conventional structural components and conventional control technology. The above content is common knowledge in the field and is not an improvement of the present invention. Therefore, it has not been explained in detail.
