Description

Technical Field

[0001] This invention relates to the field of microelectronic components technology, specifically to a lead frame detection and feeding device. Background Technology

[0002] Leadframes are a crucial component of electronic parts, and their quality directly impacts the performance of electronic products. In existing technologies, the leadframe inspection process is typically simple and quick. A suction nozzle is usually used to pick up the leadframe and then directly deliver it to the inspection area. However, this inspection method has several drawbacks.

[0003] During the testing process, it is difficult to maintain a consistent position and angle for each lead frame. Because the lead frames may tilt or shift during pickup and transport, their positional relationship with the testing equipment changes. This not only affects the accuracy of the test but may also lead to some lead frames being falsely judged as unqualified, resulting in wasted resources. Furthermore, if the lead frame is corrected after being picked up, the lead frame may detach from the nozzle, causing a deviation when the nozzle picks it up again, altering the lead frame's position and causing a secondary shift. Therefore, the existing lead frame testing and feeding device urgently needs improvement to enhance testing accuracy and production efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a lead frame inspection and feeding device, which solves the problem that the existing lead frames shift during the picking and transportation process, making it impossible to ensure uniformity when inspected on the inspection table.

[0014] Preferably, the testing mechanism further includes a testing frame, on which the testing camera and the inkjet printer are mounted, and on which a testing table is provided.

[0015] The beneficial effects of this invention are as follows: By using the lead frame detection and feeding device provided by this invention, compared with the prior art, the feeding device adopts an assembly line operation, enabling a highly efficient production process. After picking up the lead frame, the device calibrates its circumferential and axial positions on a transfer platform. While carrying the lead frame, the suction nozzle corrects the angle of the lead frame on the transfer platform. During the calibration process, the vacuum adsorption pipe remains connected to the end rod and the suction nozzle, ensuring stable suction force and preventing the lead frame from falling off during transportation and calibration. This calibration method ensures that each lead frame maintains a consistent position during detection, achieving the following effects:

[0016] 1. Improve production efficiency and realize assembly line operation: The device adopts an assembly line design with a platform, electric linear slide rail and conveying device. The storage mechanism, transfer platform and inspection mechanism are set up in sequence along the slide rail, so that the material picking, correction and inspection links of the lead frame are seamlessly connected, which greatly shortens the process interval, realizes efficient continuous production and meets the needs of large-scale production.

[0017] 2. Ensure consistent lead frame position and improve detection accuracy: The turntable, through turntable rotation, rear baffle limiting, and contact sensor feedback, can accurately correct the circumferential and axial positions of the lead frame, ensuring that each lead frame has a uniform posture on the detection table; the adsorption mechanism of the conveying device adopts a flexible connection structure of spherical cover and ball head, combined with damping ring positioning, which can flexibly adjust the angle during the correction process while maintaining stable adsorption and avoiding lead frame displacement; the above design solves the detection misjudgment problem caused by position deviation in traditional devices and improves the reliability of the detection results.

[0018] 3. Stable adsorption to prevent falling during transportation: During the calibration process, the vacuum adsorption pipe, end rod, and nozzle remain connected to ensure stable adsorption force; the transfer table further fixes the lead frame by using the negative pressure adsorption of the vacuum suction port and the opening of the transfer table; the dual adsorption protection effectively avoids the risk of the lead frame falling during handling and calibration, reducing material loss and equipment downtime adjustment time.

[0019] 4. Optimize the storage and retrieval structure to reduce operational errors: The side baffles of the storage mechanism work together with the flipping mechanism. Through the design of the mirror panel and the brush strip, it can not only ensure that the stacked lead frames are neat, but also avoid multiple pieces sticking together when retrieving materials, thus ensuring the accuracy of single retrieval. The motor-driven spindle of the flipping mechanism can flexibly realize the clamping and release of the lead frames, adapting to the storage needs of lead frames of different specifications.

[0020] 5. Integrated detection and marking functions simplify the production process: The inspection agency integrates inspection cameras and inkjet printers. After defect identification is completed on the inspection station, non-conforming locations can be marked directly without the need for additional transfer to marking equipment, which shortens the quality inspection cycle and improves the integration of processes.

[0021] In summary, through structural optimization and process innovation, this invention significantly improves production efficiency, ensures testing accuracy, and reduces material loss. It is suitable for efficient quality inspection and material loading scenarios of lead frames in the field of microelectronic components, and has strong practicality and promotional value.

[0033] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] 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. Various changes can be made to the implementation schemes as long as the effects of the present invention can be achieved.

[0035] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process.

[0036] like Figure 1 As shown in the figure, this application embodiment proposes a lead frame detection and feeding device, including a platform 1, an electric linear slide rail 2 is provided on the platform 1, a bracket 3 is provided on the sliding end of the electric linear slide rail 2, and a conveying device 6 is provided on the bracket 3; a storage mechanism 4 for storing lead frames, a transfer platform 5 and a detection mechanism are arranged sequentially along the setting direction of the electric linear slide rail 2.

[0037] During implementation, the electric linear slide rail 2 drives the conveying device 6 to grab the lead frame on the storage mechanism 4, and after adjusting its position on the transfer platform 5, it is transported to the testing mechanism for testing.

[0038] In this embodiment, as Figure 1 As shown, the inspection mechanism includes an inspection frame 7, an inspection camera 9, and an inkjet printer 10. Exemplarily, the inspection camera 9 and the inkjet printer 10 are mounted on the inspection frame 7. Furthermore, an inspection table 8 is provided on the inspection frame 7, with the inspection camera 9 and the inkjet printer 10 located above the inspection table 8.

[0039] In some embodiments, the lead frame is placed on the inspection table 8, the inspection camera 9 detects the defect location on the lead frame, and the defect location is marked by spraying with inkjet printer 10. Then, the qualified products and unqualified products are output to the corresponding qualified product table and unqualified product table for storage by the existing handling robot.

[0040] like Figures 2 to 4 As shown, the storage mechanism 4 in this embodiment includes a storage platform 41, which is used to store the lead frame to be tested. A side baffle 42 is provided on one side of the storage platform 41. One side of the stacked lead frame is attached to the side baffle 42. A flipping mechanism 44 is provided on the other side of the storage platform 41, which is opposite to the side baffle 42. In one embodiment, after the flipping mechanism 44 is flipped, it is attached to the other side of the lead frame and cooperates with the side baffle 42 to clamp the lead frame, so that the lead frame is stored flat on the storage platform 41.

[0041] Furthermore, such as Figure 2 and Figure 4 As shown, a brush strip 43 is provided above the inner wall surface of the side baffle 42. After the lead frame is picked up, the edge of the lead frame contacts the brush strip 43 to ensure that only one lead frame is picked up.

[0042] In this embodiment, as Figure 3 As shown, the tilting mechanism 44 includes two bases 441, a motor 443, a swing arm 444, and a tilting plate 445. The bases 441 are fixed on the platform 1. Specifically, a main shaft 442 is rotatably mounted on the two bases 441. The motor 443 is mounted on one of the bases 441 and is connected to the main shaft 442. The swing arm 444 is fixed on the main shaft 442. Under normal conditions, the swing arm 444 is flush with the storage platform 41 and is horizontally positioned. The tilting plate 445 is fixed on the swing arm 444. When the motor 443 drives the main shaft 442 to rotate 90°, the tilting plate 445 is perpendicular to the storage platform 41 at a 90° angle, and the tilting plate 445 is parallel to the side baffle 42.

[0043] Furthermore, in this embodiment, such as Figure 3 As shown, the flipping mechanism 44 also includes a mirror panel 446, which is fixed to the upper surface of the flipping plate 445 and is flush with the surface of the storage platform 41. The mirror panel 446 provides a flat surface for the flipping plate 445, thereby improving the neatness of the lead frame.

[0044] In some embodiments, the motor 443 drives the spindle 442 to rotate 90°, and the swing arm 444 causes the mirror panel 446 to fit against the edge of the lead frame, cooperating with the side baffle 42 to clamp the lead frame, so that the lead frame is stored flush on the storage platform 41. Then the spindle 442 rotates 90° in the opposite direction, so that the mirror panel 446 returns to a horizontal state.

[0045] In this embodiment, as Figure 5 As shown, the transfer station 5 includes a frame 51, a rear baffle 53, a turntable 52, a vacuum inlet 55, an air pipe 57, a shaft 59, and a drive mechanism 58. Specifically, the frame 51 is fixedly connected to the platform 1, the rear baffle 53 is fixedly installed on one side of the frame 51, and the turntable 52 is rotatably connected to the frame 51 via a rotating ring.

[0046] In addition, such as Figure 6 and Figure 7 As shown, the turntable 52 in this embodiment has a hollow interior forming a cavity, and its surface has several openings, forming a vacuum adsorption platform. The aforementioned vacuum suction port 55 is located inside the frame 51, and the vacuum suction port 55 is connected to a vacuum pump. The air pipe 57 is fixed to the vacuum suction port 55. One end of the shaft 59 is fixedly connected to the turntable 52, and the other end is rotatably connected to the air pipe 57. The drive mechanism 58 is connected to the shaft 59 and is used to drive the shaft 59 and the turntable 52 to rotate.

[0047] The drive mechanism 58 includes a servo motor and a pulley. The pulley is located at the output end of the servo motor and on the shaft 59. The servo motor drives the shaft 59 to rotate through the pulley.

[0048] In some embodiments, the transport device 6 lowers the lead frame onto the turntable 52. The vacuum pump operates to generate negative pressure, which acts through the vacuum suction port 55 into the hollow cavity inside the turntable 52 and onto the opening, adsorbing and fixing the lead frame. The turntable 52 is driven by the drive mechanism 58 to rotate, causing the lead frame to be rotated and adjusted to fit against the rear baffle 53. After the lead frame is aligned, it is transported by the transport device 6 to the testing table 8.

[0049] Furthermore, such as Figure 6 As shown, in this embodiment, panels 54 are provided on both sides of the front end of the rear baffle 53, and contact sensors 56 are provided between the two panels 54 and the rear baffle 53.

[0050] When the turntable 52 rotates and calibrates the lead frame, the contact sensor 56 transmits a signal to the control device after both sides of one side of the lead frame contact the panel 54. When the contact sensor 56 is triggered after both sides of the lead frame touch the two panels 54, it indicates the calibrated position of the lead frame, ensuring that each lead frame is in the same position after being delivered to the detection table 8, thus guaranteeing the accuracy of the image captured by the detection camera 9.

[0051] In this embodiment, as Figure 8 and Figure 9 As shown, the conveying device 6 includes a conveying platform 61, an electric telescopic rod 62, a fixing block 64, and a suction mechanism. The conveying platform 61 is fixed to the bracket 3, the electric telescopic rod 62 is fixed to the conveying platform 61, and its output end passes through the conveying platform 61. The fixing block 64 is fixed to the output end of the electric telescopic rod 62, and the suction mechanism is mounted on the fixing block 64.

[0052] For example, the electric telescopic rod 62 drives the fixed block 64 to move up and down, and the adsorption mechanism realizes the adsorption and placement of the lead frame.

[0053] In this embodiment, as Figure 9 As shown, the adsorption mechanism includes a vacuum adsorption pipe 63 and an end rod 67. The vacuum adsorption pipe 63 passes through the transport table 61 and the fixing block 64 in sequence, and a spherical cover 66 is provided at the bottom of the vacuum adsorption pipe 63. One end of the end rod 67 is provided with a suction nozzle 65, and the other end is provided with a ball head 610, which is embedded in the spherical cover 66.

[0054] Furthermore, such as Figure 10 As shown, the spherical cover 66 here has an annular groove 68 circumferentially opened in the inner cavity, and a damping ring 69 is embedded in the annular groove 68; the outer wall of the ball head 610 is provided with an annular protrusion 611 circumferentially, the annular protrusion 611 is embedded in the annular groove 68 and abuts against the damping ring 69.

[0055] In some embodiments, after the suction nozzle 65 adsorbs the lead frame on the storage platform 41 and transports it to the turntable 52, during the rotation adjustment process of the turntable 52, the vacuum adsorption pipe 63 is in a fixed state, and the end rod 67 carries the suction nozzle 65 to rotate. At this time, the ball head 610 swings circumferentially or axially within the spherical cover 66. At this time, the annular protrusion 611 moves within the annular groove 68 and is positioned at any point on the movement trajectory by the damping ring 69, so that the suction nozzle 65, while carrying the lead frame, corrects the angle of the lead frame on the turntable 52. During the correction process, the vacuum adsorption pipe 63, the end rod 67, and the suction nozzle 65 remain in communication to ensure the adsorption force of the suction nozzle 65.

[0056] The working principle is as follows:

[0057] The device uses platform 1 as the basic carrier, and drives support 3 and handling device 6 to move along the direction of electric linear slide rail 2 through electric linear slide rail 2, and sequentially completes the whole process of picking up material from storage mechanism 4, correction of transfer platform 5, and detection by detection mechanism; each link combines mechanical structure and vacuum adsorption technology to ensure that the lead frame is stable and reliable during transportation and handling.

[0058] The storage mechanism 4 is used to store the lead frame to be tested. Its core is to achieve the neat stacking and separation of the lead frame through the cooperation of the side baffle 42 and the flipping mechanism 44.

[0059] In the stacked state, one side of the lead frame is attached to the side baffle 42, and the other side is positioned by the mirror panel 446 of the flipping mechanism 44; the motor 443 drives the main shaft 442 to rotate, which drives the swing arm 444 and the flipping plate 445 to rotate, and the mirror panel 446 and the side baffle 42 form a clamping force to ensure that the edges of the stacked lead frames are flush.

[0060] During material handling, the flipping mechanism 44 is reset to a horizontal state, and the brush strip 43 on the inner wall of the side baffle contacts the edge of the lead frame. The friction force is used to prevent multiple pieces from sticking together, ensuring that the handling device 6 can only pick up one lead frame at a time.

[0061] The handling device 6, through the cooperation of the electric telescopic rod 62 and the adsorption mechanism, realizes the gripping and transfer of the lead frame:

[0062] The electric telescopic rod 62 drives the fixed block 64 to descend. After the suction nozzle 65 contacts the lead wire frame, the vacuum adsorption pipe 63 is activated. The negative pressure is transmitted to the suction nozzle through the end rod 67, generating an adsorption force to grab the lead wire frame.

[0063] The flexible connection structure between the spherical cover 66 and the ball head 610 allows the suction nozzle 65 to adjust its angle within a certain range. The contact between the annular protrusion 611 and the damping ring 69 ensures that the angle remains stable after adjustment. At the same time, the vacuum adsorption pipe 63 is always connected to the end rod 67 and the suction nozzle 65 to ensure that the adsorption force remains stable during transportation and to prevent it from falling off.

[0064] The electric linear slide rail 2 drives the support 3 to move, transferring the lead frame from the storage mechanism 4 to the transfer platform 5, and then from the transfer platform 5 to the testing mechanism.

[0065] Transit station 5 is a key component for achieving precise alignment of the lead frame's position and angle. This alignment is accomplished through a combination of mechanical limiting and vacuum adsorption.

[0066] After the lead frame is moved to the turntable 52, the vacuum pump delivers negative pressure to the hollow cavity inside the turntable 52 through the vacuum suction port 55 and the air pipe 57, and uses the openings on the surface of the turntable 52 to adsorb and fix the lead frame.

[0067] The drive mechanism 58 drives the drive shaft 59 to rotate the turntable. The lead frame rotates with the turntable 52 until its edge is in contact with the back baffle 53. After the contact sensor 56 in the two side panels 54 detects the contact signal of the lead frame, the turntable stops rotating, completing the axial and circumferential position correction.

[0068] During the calibration process, the suction nozzle 65 of the transport device 6 remains in an adsorption state. The flexible structure of the spherical cover 66 and the ball head 610 adapts to the rotation angle of the turntable, ensuring that the lead frame does not detach from the adsorption during adjustment.

[0069] The inspection agency achieves quality inspection and defect marking through the coordinated operation of the inspection camera 9 and the inkjet printer 10:

[0070] The corrected lead frame is transferred to the inspection station 8, where the inspection camera 9 acquires images of it to identify surface defects or dimensional deviations.

[0071] If a non-conforming item is detected, the inkjet printer 10 will spray a mark on the defective location; qualified products will directly proceed to the next process; inspection and marking are completed on the same platform, reducing transfer links and improving efficiency.

[0072] As the core driving component, the electric linear slide rail 2 controls the movement path of the support 3, enabling the conveying device 6 to precisely switch between the storage mechanism 4, the transfer platform 5, and the detection mechanism. The actions of each link are triggered by the contact sensor 56 and linked with the control system. For example, the calibration completion signal of the transfer platform 5 triggers the electric linear slide rail 2 to drive the conveying device 6 to move towards the detection mechanism, ensuring that there is no delay in the connection of processes.

[0073] In summary, the device achieves efficient and automated processing of lead frames from storage to detection through precise mechanical structure coordination, stable vacuum adsorption, and automated control logic. It solves problems such as position deviation and drop risk in traditional feeding processes, and meets the high precision and high efficiency requirements of microelectronic component production.
