Abstract
Description
Technical Field
[0001] This invention relates to the field of BGA chip inspection, and in particular to an automatic continuous X-ray inspection device for BGA chips. Background Technology
[0002] BGA (Ball Grid Array) is a chip packaging technology that uses solder balls as interconnect points on the bottom. Its core advantages are high-density interconnection and good heat dissipation, and it is widely used in the semiconductor field. X-ray inspection equipment is a non-destructive inspection device specifically designed for defects in hidden solder joints on the bottom of BGA chips. By using X-rays to penetrate the chip package, it can clearly reveal key information such as the soldering quality, position, and shape of the solder balls. It is a core piece of equipment in semiconductor packaging and electronic manufacturing to ensure product reliability.
[0003] Traditionally, BGA chip X-ray inspection equipment requires placing the circuit board containing the chips, or a tray carrying multiple BGA chips, centrally within the X-ray inspection unit before inspection. This process is inefficient, and manual placement introduces positional errors, affecting inspection accuracy. Therefore, an automated continuous X-ray inspection device for BGA chips is proposed.

The upper output end of each telescopic component is connected to the lower end of the support plate, and the front and rear sides of the support plate abut against the upper end surfaces of the front and rear push seats.
[0015] The beneficial effects of this invention are: 1. The technical solution of the present invention can transport the chip between the front and rear horizontal centering pushers by a conveyor belt. Then, the telescopic component is controlled to move down, thereby driving the tray to move down, which can push the pusher and slide down. Then, when the turntable rotates, it pulls the front and rear sliding frames and the horizontal centering pushers closer to each other, which can realize the centering and limiting of the chip on the conveyor belt. It can realize the horizontal automatic centering placement, avoid manual labor, improve efficiency and placement accuracy. 2. The technical solution of this invention uses a telescopic component to move the pallet upward, causing the front and rear transverse centering pushers to move away from each other and reset. At the same time, the pallet moves upward and the chip is lifted from the conveyor belt by the tray connected to the upper end of the sliding rod 2 that is slidably sleeved on it. When the front and rear sides of the pull plate contact the abutment, the pull plate will move downward relative to the pallet, thereby driving the rotating plate 2 to pull the two longitudinal centering pushers closer to each other. During the process, the tray will follow the pull plate downward until it contacts the upper surface of the pallet. At this time, the two longitudinal centering pushers also simultaneously achieve longitudinal centering limit of the chip on the tray. Then, the pallet is controlled to move downward, so that the pull plate and the tray move upward and reset. This allows the chip on the tray to be positioned above the two longitudinal centering pushers, avoiding the obstruction of the two longitudinal centering pushers during detection. This allows the chip to be placed centered on the tray, and the whole process is automated without manual intervention, improving efficiency and detection accuracy. 3. The technical solution of the present invention uses collars connected to both sides of the push base and sleeved with the sleeve wheels. The sleeve wheels are connected to the slide frame that slides on the slide base. When the bidirectional telescopic component drives the two support frames to move closer or further apart, the sleeves and sleeve wheels will hold the slide frame still. The sliding of the support frame will cause the slide base to slide relative to different slide frames. This ensures that the adjustment distance of the front and rear conveyor belts can be adjusted to accommodate the detection of chips of different widths. At the same time, it can maintain the connection between the slide base and the push base. When the tray moves down and comes into contact with the push base, it can drive the slide base down and pull the front and rear horizontally centered push bases closer together, so as to place the chip horizontally in the center. This improves the flexibility of adjustment and the versatility of chip detection. Attached Figure Description

[0018] The following will be combined with the appendix Figure 1 To be continued Figure 10 The technical solutions in the embodiments of the present invention have been clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.
[0019] Example 1: like Figures 1-10 As shown, this invention discloses an automatic continuous X-ray inspection device for BGA chips, including a chassis 1. A base 4 is connected to the bottom of the chassis 1, and slide rails 5 are connected to both sides of the base 4. An automatic X-ray inspection component is installed on the inner wall of the chassis 1. Bidirectional telescopic members 7 are installed in the center of both slide rails 5. Support frames 8 are symmetrically connected to the output ends of the bidirectional telescopic members 7 on both the front and rear sides. A conveyor belt 12 is installed on the upper end of the support frame 8. A protective plate 13 is also connected to the support frame 8 on the same side of the front and rear sides, which is located on the side away from the front and rear conveyor belts 12. A sliding frame 16 is slidably fitted on the side away from the front and rear protective plates 13. The sliding frame 16 extends around the protective plate 13 to the side where the front and rear protective plates 13 are close to each other. The extended end of the sliding frame 16 is connected to a sleeve plate 18 that is above the conveyor belt 12 and parallel to the conveyor belt 12. A sleeve 18 is slidably fitted with multiple slide rods 19, and the slide rods 19 are connected to a top plate 20 at the upper end of the sleeve 18. A horizontal centering pusher 21 for centering the BGA chip is connected to the lower end of the sleeve 18. A slide block 24 is slidably connected to the bracket frame 8. A rotating plate 25 is rotatably connected between the slide block 24 and the slide frame 16. A pusher 30 is slidably connected to the base 4. A linkage component is provided on the pusher 30 to slide and associate the pusher 30 with the slide block 24. A support plate 33 is provided inside the base 4. A centering component is provided on the support plate 33 to center the BGA chip left and right. A drive component is provided inside the chassis 1 to drive the pusher 30 or the support plate 33 to slide.
[0020] The chassis 1 has conveying ports 2 and equipment ports 3 on both sides. The base 4 extends through the equipment ports 3 to the two outer sides of the chassis 1. The slide rails 5 are connected to the two extended ends of the base 4. The conveyor belt 12 extends through the conveying ports 2 to the two outer sides of the chassis 1. Each support frame 8 has a guide block 9 connected to its lower end. The guide block 9 is slidably connected in the slide rail 5. The lower end of each slide rail 5 is connected to a horizontal support base 6 at the bottom of the chassis 1, so that both ends of the conveyor belt 12 can extend to the two outer sides of the chassis 1. This facilitates placing chips from the outside to one end of the conveyor belt 12 using existing equipment such as robotic arms. The chips then enter the chassis 1 through the conveying port 2 on this side for testing. After testing, the chips are transferred out through the conveying port 2 on the other side and transferred to the next process by the same existing equipment such as robotic arms.
[0021] A servo motor 10 is installed at the upper end of the support frame 8, and a pulley 11 is installed at the output end of the servo motor 10. The conveyor belt 12 is fitted on the outside of the two pulleys 11 on the same side at the front and rear. A concave frame 14 is provided on the support frame 8 to accommodate the transverse centering push seat 21, so as to realize synchronous electric control of the front and rear conveyor belts 12 and maintain the synchronous operation of the front and rear conveyor belts 12.
[0022] Each of the front and rear side guard plates 13 is connected to a slide rod frame 15 on the side away from each other. Each of the front and rear side slide frames 16 is slidably sleeved on the outside of the slide rod frame 15 on the side away from each other. A spring 17 is connected between the slide frame 16 and the guard plate 13 and is sleeved on the outside of the slide rod frame 15. The lower end of the top plate 20 is rotatably fitted with a ball bearing 22 that is rollingly connected to the surface of the conveyor belt 12. This allows the front and rear slide frames 16 to slide away from each other until they are in contact with the side away from each other of the front and rear slide rod frames 15 when no external force is applied. At this time, the transverse centering push seat 21 on the front and rear sides is located at the edge of the conveyor belt 12 on the side of each other, reducing the occupation of the conveyor belt 12. At the same time, the interactive sleeved arrangement of the slide frame 16 and the slide rod frame 15 can also ensure excellent stability when sliding.
[0023] A second slide rod 23 is connected to the support frame 8. A slide seat 24 is slidably fitted on the outside of the second slide rod 23. A second spring 26 is connected between the lower end of the slide seat 24 and the support frame 8 and is fitted on the outside of the second slide rod 23. A third slide rod 29 is connected to the base 4. A push seat 30 is slidably fitted on the outside of the third slide rod 29, so that the slide seat 24 can slide stably on the outside of the second slide rod 23, and the push seat 30 will also slide stably on the outside of the third slide rod 29. Without the action of external force, the slide seat 24 and the push seat 30 are pushed upward by the elastic force of the second spring 26.

[0028] Example 3: like Figures 1-10 As shown, this invention discloses an automatic continuous inspection device for BGA chip X-ray. Compared with Embodiment 2, this embodiment discloses the structure of the linkage component.
[0029] An automatic continuous X-ray inspection device for BGA chips includes a chassis 1, a base 4 connected to the bottom of the chassis 1, and slide rails 5 connected to both sides of the base 4. An automatic X-ray inspection component is installed on the inner wall of the chassis 1. Bidirectional telescopic components 7 are installed in the center of both slide rails 5. Support frames 8 are symmetrically connected to the output ends of the bidirectional telescopic components 7 on both the front and rear sides. A conveyor belt 12 is installed on the upper end of the support frame 8. A protective plate 13 is also connected to the support frame 8 on the same side of the front and rear sides, which is located on the side away from the front and rear conveyor belts 12. A sliding frame 16 is slidably fitted on the side away from the front and rear protective plates 13. The sliding frame 16 extends around the protective plate 13 to the side where the front and rear protective plates 13 are close to each other. The extended end of the sliding frame 16 is connected to a sleeve plate 18 that is above the conveyor belt 12 and parallel to the conveyor belt 12. A sleeve 18 is slidably fitted with multiple slide rods 19, and the slide rods 19 are connected to a top plate 20 at the upper end of the sleeve 18.

[0031] When the bidirectional telescopic component 7 drives the two side support frames 8 to move closer or further apart, the sleeve of the collar 31 and the sleeve wheel 28 will hold the slide 27 still, while the sliding of the support frame 8 will cause the slide 24 to slide relative to the stationary slide 27. This ensures that the front and rear conveyor belts 12 can be adjusted to accommodate the detection of chips of different widths, while also maintaining the connection between the slide 24 and the pusher 30.
[0032] Example 4: like Figures 1-10 As shown, this invention discloses an automatic continuous inspection device for BGA chip X-ray. Compared with Embodiment 3, this embodiment discloses the structure of the centering component.
[0033] An automatic continuous X-ray inspection device for BGA chips includes a chassis 1, a base 4 connected to the bottom of the chassis 1, and slide rails 5 connected to both sides of the base 4. An automatic X-ray inspection component is installed on the inner wall of the chassis 1. Bidirectional telescopic components 7 are installed in the center of both slide rails 5. Support frames 8 are symmetrically connected to the output ends of the bidirectional telescopic components 7 on both the front and rear sides. A conveyor belt 12 is installed on the upper end of the support frame 8. A protective plate 13 is also connected to the support frame 8 on the same side of the front and rear sides, which is located on the side away from the front and rear conveyor belts 12. A sliding frame 16 is slidably fitted on the side away from the front and rear protective plates 13. The sliding frame 16 extends around the protective plate 13 to the side where the front and rear protective plates 13 are close to each other. The extended end of the sliding frame 16 is connected to a sleeve plate 18 that is above the conveyor belt 12 and parallel to the conveyor belt 12. A sleeve 18 is slidably fitted with multiple slide rods 19, and the slide rods 19 are connected to a top plate 20 at the upper end of the sleeve 18. A horizontal centering pusher 21 for centering the BGA chip is connected to the lower end of the sleeve 18. A slide block 24 is slidably connected to the bracket frame 8. A rotating plate 25 is rotatably connected between the slide block 24 and the slide frame 16. A pusher 30 is slidably connected to the base 4. A linkage component is provided on the pusher 30 to slide and associate the pusher 30 with the slide block 24. A support plate 33 is provided inside the base 4. A centering component is provided on the support plate 33 to center the BGA chip left and right. A drive component is provided inside the chassis 1 to drive the pusher 30 or the support plate 33 to slide.
[0034] The centering component includes a slide opening 34, a longitudinal centering pusher 35, a guide ramp 36, a slide rod bracket 37, a slide rod 39, a tray 40, and a pull plate 41. The slide opening 34 extends through the left and right sides of the tray 33. The longitudinal centering pusher 35 is slidably fitted inside the slide opening 34 and extends to the upper and lower sides of the tray 33. The guide ramp 36 is connected to the extension end of the longitudinal centering pusher 35 on the upper side of the tray 33. The slide rod 39 slides centrally through the tray 33, and the tray 40 and pull plate 41 are respectively connected to the extension ends on the upper and lower sides of the tray 33. The upper end of the tray 40 is used to support the BGA. The chip and the slide bracket 37 are connected to the lower end of the support plate 33. The longitudinal centering push seats 35 on both sides are slidably sleeved on the outside of the slide bracket 37 at the lower end of the support plate 33. The longitudinal centering push seats 35 on both sides are connected to each other on one side by a spring 38 sleeved on the outside of the slide bracket 37. The pull plate 41 is rotatably connected to the longitudinal centering push seats 35 on both sides by a rotating plate 2 42. The front and rear ends of the pull plate 41 abut against the inner wall of the support frame 8 on the front and rear sides. The lower end of the support frame 8 is connected to a stop 43. The front and rear sides of the pull plate 41 extend to the bottom of the stop 43 and abut against the lower end surface of the stop 43.
[0035] The drive mechanism moves the tray 33 downwards, which in turn pushes the pusher 30 and slide 24 downwards. This causes the turntable 25 to rotate, pulling the front and rear sliding frames 16 and the horizontal centering pusher 21 closer together. This allows for centering and limiting the chips on the conveyor belt 12, achieving automated horizontal centering placement, avoiding manual labor, improving efficiency and placement accuracy. Then, the tray 33 is moved upwards, causing the front and rear horizontal centering pushers 21 to move away from each other and reset. Simultaneously, the tray 33 moves upwards, and the chip is lifted from the conveyor belt 12 by the tray 40 connected to the upper end of the sliding rod 39, which is slidably fitted on it. This continues until the front and rear sides of the pull plate 41 abut against the abutment 43, at which point the pull plate 41 will move downwards relative to the tray 33. The movement causes the rotating plate 42 to pull the two longitudinal centering pushers 35 closer together. During this process, the tray 40 will move down with the pull plate 41 until it touches the upper surface of the tray 33. At this time, the two longitudinal centering pushers 35 also simultaneously achieve longitudinal centering limit on the chip on the tray 40. Then, the tray 33 is controlled to move down, so that the pull plate 41 and the tray 40 move up and reset. This allows the chip on the tray 40 to be positioned above the two longitudinal centering pushers 35, avoiding obstruction by the two longitudinal centering pushers 35 during testing. This allows the chip to be placed centered on the tray 40. The entire process is automated, and the chips on the conveyor belt 12 can be continuously transported without manual intervention, improving efficiency and testing accuracy.
