Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor packaging inspection, and in particular to a semiconductor packaging quality visual inspection device. Background Art

[0002] Semiconductor packaging refers to the process of encapsulating semiconductor chips in microelectronic devices with a protective shell. The main purpose of packaging is to protect semiconductor chips from mechanical, chemical or environmental damage and provide electrical connections for the chips.

[0003] Visual inspection of packaging quality is crucial in the semiconductor manufacturing process. It can effectively ensure product quality, reduce defective rates, and improve production efficiency. During visual inspection, the light source can ensure that the surface of the inspected object is evenly illuminated, thereby improving the brightness and clarity of the image. Selecting the appropriate light source color based on the inspected object and the required information can enhance or weaken the visibility of specific features.

[0004] Optical filters are a simple and direct method that can be placed in front of a light source to selectively filter out unnecessary light and allow only light of a specific wavelength to pass, thereby changing the color of the light source. In the prior art, since the optical filter in front of the light source is single, during the detection process, workers need to frequently replace the optical filter to adapt to different detection needs. However, each time the filter is replaced, the detection process needs to be stopped, which reduces the detection efficiency.

[0005] And because the light source is located close to the detection target, the operating space is narrow. The user needs to lift the light source away from the target before replacing it. After each filter replacement, the brightness and position of the light source need to be readjusted, which will cause the stability of the light source to decrease, affecting the image quality and further affecting the accuracy of the detection results.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-Figure 6 The present invention provides a technical solution: a semiconductor packaging quality visual inspection device, comprising a body 1, a conveying mechanism 2 installed on the body 1 and an industrial camera 3, a lamp tube 5 is rotatably installed on the side end of the industrial camera 3 through an equipment frame 4, a turntable 6 is rotatably connected in the lamp tube 5, a side tube 7 is coaxially fixed on the turntable 6, a plurality of rotating plates 11 distributed in an annular shape are movably arranged on the outer side of the turntable 6, and a lamp cover 25 is rotatably connected to the rotating plate 11.

[0033] The conveying mechanism 2 adopts the existing conveyor belt conveying method, is installed on the machine body 1, and is used to convey the semiconductor packaged products to be inspected, and convey the semiconductor packaged products to the inspection area of ​​the industrial camera 3. The industrial camera 3 is an existing technology, and is used to capture the image of the product to be inspected for visual inspection. The lamp tube 5 is rotatably installed on the equipment frame 4 to ensure that the position of the lamp tube 5 can be flexibly adjusted.

[0034] The filters installed on the multiple lampshades 25 are of different colors. Through the design of the rotary disk 6 and the rotary plate 11, a multi-color LED light source can be conveniently integrated. Thus, the switching of light sources of multiple colors can be realized, thereby enhancing the visibility of specific features and improving the accuracy of detection. In addition, through the combination of the automatic conveying mechanism 2 and the multi-color LED light source, the automation of the detection process can be realized, manual intervention can be reduced, and the detection efficiency and accuracy can be improved.

[0035] A sliding frame 16 and a telescopic rod 17 for controlling the movement of the sliding frame 16 are provided on the lamp tube 5. A retaining groove 15 for the sliding frame 16 to be embedded is formed in the rotary plate 11. A transmission member corresponding to the rotary plate 11 is provided on the outer side of the rotary disk 6. When the sliding frame 16 slides toward the side tube 7, the rotary plate 11 first rotates away from the side tube 7 under the action of the transmission member, and the lampshade 25 rotates and unfolds relative to the rotary plate 11 under the action of gravity. When the lampshade 25 is aligned with the lamp holder of the lamp tube 5, the sliding frame 16 presses the inner wall of the retaining groove 15 to sleeve the lamp tube 5 on the outer side of the lamp holder.

[0036] The telescopic rod 17 is a conventional hydraulic or pneumatic telescopic method, which controls the movement of the sliding frame 16 so that it can be flexibly moved close to or away from the side tube 7, thereby realizing the unfolding and folding of the lampshade 25. When the side tube 7 rotates to switch the position of the lampshade 25, the rotating plate 11 and the lampshade 25 are in a folded state, which reduces the space occupied by the device and makes the device more compact, thereby facilitating the free switching of the lampshade 25 with different filter colors in a small space.

[0037] When the lampshade 25 is opened and aimed at the lamp head of the lamp tube 5, the sliding frame 16 is embedded in the groove 15. As the sliding frame 16 continues to move, it will push the inner wall of the groove 15 so that the opened lampshade 25 is fixed on the outside of the light source to avoid light leakage, thereby ensuring the background of the detection image is clear, enhancing the visibility of specific features, and improving the accuracy of detection.

[0038] A rod 30 penetrating the turntable 6 and the side tube 7 is fixedly provided at the side end of the lamp tube 5. An electric control component for controlling the rotation of the side tube 7 is provided on the rod 30. A limiting structure for limiting the free rotation of the turn plate 11 is provided on the side of the rod 30. A compression structure for limiting the expansion of the lampshade 25 relative to the turn plate 11 is provided on the side of the side tube 7.

[0039] The design of the support rod 30 makes the structure of the rotating disk 6 and the side tube 7 more stable, ensuring that there will be no loosening or deviation during the rotation process, thereby improving the reliability and stability of the equipment. The support rod 30 is provided with an electric control component for controlling the rotation of the side tube 7, realizing automatic control and reducing manual intervention. The coordinated setting of the limit structure and the compression structure can limit the idle lampshade 25 from freely unfolding relative to the rotating plate 11. This design ensures the stability of the lampshade 25 when idle, and avoids the lampshade 25 unfolding due to accidental collision or vibration, which affects the detection.

[0040] Specifically, Figure 3-Figure 5 As shown, the sliding frame 16 is a bent structure, and the transmission part includes a tooth plate 22 slidably connected to the inside of the side tube 7, and a component that drives the tooth plate 22 to slide. The outer end of the rotary disk 6 is fixed with a bracket 8 corresponding to the rotary plate 11, and the bracket 8 is rotatably connected with a gear 9 that engages with the tooth plate 22.

[0041] When the sliding frame 16 moves under the action of the telescopic rod 17 , the corresponding tooth plate 22 will slide along the side tube 7 under the action of the transmission member, and the gear 9 will rotate under the meshing action of the tooth plate 22 .

[0042] A bar block 10 coaxially fixed with the gear 9 is rotatably connected to the bracket 8, a notch 12 for cooperating with the gear 9 and a groove 13 for cooperating with the sliding of the bar block 10 are formed in the rotary plate 11, and a magnetic sheet 14 with repelling magnetic poles is installed on the inner wall of the groove 13 at one end opposite to the bar block 10.

[0043] When the gear 9 rotates, the strip block 10 coaxially fixed with the gear 9 will drive the rotary plate 11 to rotate by acting on the inner wall of the groove 13. Before the inner wall of the abutment groove 15 in the rotary plate 11 is not pressed by the sliding frame 16, the sliding frame 16 will remain in an extended state under the action of the repelling magnetic sheet 14 until the lampshade 25 is rotated and unfolded to align with the lamp holder of the lamp tube 5. At this time, the sliding frame 16 will be embedded in the abutment groove 15. As the sliding frame 16 continues to lean against the side tube 7, the sliding frame 16 will act on the inner wall of the abutment groove 15, so that the rotary plate 11 overcomes the repulsive force of the magnetic sheet 14 and drives the unfolded lampshade 25 to be sleeved on the outside of the lamp holder.

[0044] The component that drives the tooth plate 22 to slide includes a slide arm 19 slidably connected to the turntable 6, and a docking structure. A protrusion 21 is fixed to the side end of the slide arm 19, and a slide groove 23 is formed inside the tooth plate 22 to cooperate with the sliding of the protrusion 21. The slide groove 23 consists of a transverse groove and an oblique groove.

[0045] When the protrusion 21 slides along the oblique groove of the slide groove 23, the protrusion 21 presses the inner wall of the oblique groove to drive the tooth plate 22 to slide along the side tube 7, and the rotary plate 11 is in a rotating state. When the protrusion 21 slides to the horizontal groove of the tooth plate 22, the sliding frame 16 will act on the inner wall of the groove 15 to push the rotary plate 11 to move. During this process, the tooth plate 22 will remain stationary relative to the side tube 7, and the rotary plate 11 will remain in the same horizontal state with the side tube 7, which is conducive to the docking of the unfolded lampshade 25 with the lamp head of the lamp tube 5.

[0046] The docking structure includes a round block 18 fixedly mounted on the bottom of the sliding frame 16 , and an open groove 20 is formed in the sliding arm 19 for the round block 18 to slide and embed.

[0047] When the sliding arm 19 rotates with the rotary disk 6, the round block 18 at the bottom of the sliding frame 16 is circumferentially embedded in the open groove 20 thereof, and at this time, by controlling the movement of the sliding frame 16, the sliding arm 19 can be driven to move synchronously by the pressure of the round block 18 on the inner wall of the open groove 20. Through the cooperation of the round block 18 and the open groove 20, the sliding frame 16 can correspondingly control the rotary plate 11 switched to a position, thereby conveniently switching the color of the light source.

[0048] Specifically, Figure 4As shown, the electric control component includes a motor 32 mounted on the frame rod 30, and a support arm 33 is installed on the inner wall of the side tube 7, and the output end of the motor 32 is fixed to the support arm 33. The use of the motor 32 can realize the automatic rotation of the side tube 7, reduce manual intervention, and improve the detection efficiency and accuracy. By controlling the rotation of the motor 32, accurate light source switching and position adjustment can be achieved. The design of the support arm 33 can ensure that the connection between the output end of the motor 32 and the side tube 7 is stable, so that the motor 32 can quickly drive the side tube 7 to rotate through the support arm 33, and realize the rapid switching of different color filters.

[0049] Specifically, Figure 4 As shown, the limiting structure includes a guide rod 24 fixed to the inner end of the tooth plate 22, and a guide groove 31 is formed on the side wall of the frame rod 30 to cooperate with the sliding of the guide rod 24, and the guide groove 31 is composed of an annular groove and a branch groove.

[0050] When the switched rotary plate 11 rotates to the position along with the side tube 7, the guide rod 24 fixed on the tooth plate 22 slides to the intersection of the annular groove and the branch groove. At this time, due to the existence of the branch groove, the movement of the tooth plate 22 relative to the side tube 7 will not be restricted. The movement of the tooth plate 22 controls the retraction and extension state of the rotary plate 11. When the rotary plate 11 is in the folded state, the guide rod 24 is located in the annular groove. When the side tube 7 rotates, the guide rod 24 will slide along the annular groove. The annular groove restricts the random sliding of the tooth plate 22 relative to the side tube 7, thereby ensuring that the rotary plate 11 maintains a stable folded state.

[0051] Specifically, Figure 2-Figure 4 As shown, the compression structure includes a swing arm 26 which is rotatably connected to the outside of the stopper 27 and coaxially fixed with the lampshade 25. A cross bar 28 is fixedly provided on the inner side of the swing arm 26. A side extension frame 29 for acting on the cross bar 28 is fixedly provided on the side end of the side tube 7. A stopper 27 for limiting the rotation range of the swing arm 26 is fixedly provided on the outer end of the swing plate 11.

[0052] When the rotary plate 11 rotates and rotates away from the side tube 7, the cross bar 28 is also separated from the side extension frame 29. At this time, the state of the lampshade 25 relative to the rotary plate 11 will not be restricted. During the downward rotation of the rotary plate 11, the lampshade 25 will also rotate and unfold relative to the rotary plate 11 under the action of gravity until the rotary arm 26 abuts against the stopper 27, which will limit the continued unfolding of the lampshade 25. At this time, the lampshade 25 and the rotary plate 11 are vertically distributed.

[0053] When the rotary plate 11 rotates toward the side tube 7, the side extension frame 29 fixed on the side tube 7 will contact the side wall of the cross bar 28. The side wall of the side extension frame 29 pushes the cross bar 28, driving the rotary arm 26 fixed to the cross bar 28 to drive the lampshade 25 to rotate and fold.

[0054] Specifically, Figure 2-Figure 4As shown, a shielding plate 1101 is fixedly provided on the rotating plate 11 to seal the inner cavity of the lampshade 25 , and a blowing mechanism 34 for cleaning the surface of the lampshade 25 is installed at the outer end of the lampshade 25 .

[0055] The blowing mechanism 34 provides high-pressure airflow through a compressed air source (air compressor) in the prior art. When the compressed air passes through the nozzle of the air blowing hanger, the airflow speed is accelerated and the pressure is reduced, forming a strong airflow impact force, thereby cleaning the surface of the lampshade 25.

[0056] When the lampshade 25 is rotated and folded relative to the rotating plate 11, the baffle 1101 fixed on the rotating plate 11 will block the inner cavity of the lampshade 25, thereby preventing dust or impurities from entering the inner cavity of the lampshade 25. The blocking of the baffle 1101 can reduce the accumulation of dust and impurities, making the maintenance of the inner cavity of the lampshade 25 more convenient, reducing maintenance time and cost. When the lampshade 25 is rotated toward the blowing mechanism 34 as the rotating disk 6 rotates, the blowing mechanism 34 will blow and clean the outer surface of the lampshade 25. This design can automatically remove dust and impurities on the surface of the lampshade 25, ensure the uniformity and stability of the light source, reduce light scattering and reflection caused by dust and impurities, and improve the accuracy and reliability of detection.

[0057] The design of this folding structure allows the staff to directly cover the outer side of the side tube 7 with the cylindrical cover when the equipment is idle, and the cylindrical cover can cover multiple lampshades 25 at one time, reducing the operation steps and improving the maintenance efficiency. This design makes the equipment tidier when idle and reduces the accumulation of dust and impurities.

[0058] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
