Abstract
Description
Technical Field
[0001] This utility model belongs to the field of semiconductor integrated circuit manufacturing technology, and relates to a tape track for tape inspection. Background Technology
[0002] During tape and cord inspection, excessive bending or excessive width of the carrier tape can lead to damage. This damage is usually caused by excessive mechanical stress on the carrier tape as it runs on the track, or a mismatch between the track width and the carrier tape size. Damaged carrier tape cannot be used directly and must be reworked in its entirety. This not only wastes raw materials and reduces product yield but also affects the utilization rate of the tape and cord inspection machine, resulting in decreased production efficiency. Furthermore, if an improper track width is discovered during operation, the carrier tape is likely already damaged. Even if the carrier tape is not damaged, the operator must remove the current carrier tape, wait for the track to be adjusted, and then reinsert the carrier tape to continue inspection. This process is not only time-consuming but also wastes manpower, further reducing production efficiency.
[0003] To address these issues, operators typically adjust the carrier tape track width to be slightly wider than the carrier tape itself. However, while this reduces the risk of carrier tape damage, it introduces new problems. When the track width is wider than the carrier tape, the vertical movement of the carrier tape within the track increases significantly, leading to instability in the chip's position. This instability directly affects the accuracy of the tape-and-reel inspection equipment, resulting in inaccurate chip inspection results, potentially causing missed or false detections, ultimately impacting product quality.
[0004] Therefore, how to provide a tape tray for tape inspection to solve the problems of rework and inaccurate inspection results caused by tape inspection equipment operation, and improve the utilization rate of the machine, has become an important problem that needs to be solved by those skilled in the art.

[0067] This utility model provides a tape feeding track for tape feeding inspection. Please refer to [link / reference]. Figures 1 to 3 , Figure 1 The image shown is a top-side view of the structure of the tape feeding track for tape feeding inspection according to this utility model. Figure 2 This diagram illustrates the connection relationship between the tape width adjustment component, the conveying component, and the torque detector in the tape track used for tape inspection according to this invention. Figure 3 The diagram shows a front view of the tape feeding track for tape feeding inspection according to this utility model. The tape feeding track includes a track assembly 1, a width adjustment assembly 2, a conveying assembly 3, and a torque detector 5. Figure 1 and Figure 3 For torque detectors not labeled, please refer to [link / reference]. Figure 2 The track assembly 1 includes a first track 101 and a second track 102 that are disposed opposite to each other.
[0068] Specifically, the width adjustment component 2 is located below the track component 1 and includes a first motor 201 and a screw 202 connected sequentially along the X direction. The X direction points from the first track 101 to the second track 102. A slider 203 is sleeved on the screw 202, and the slider 203 is fixedly connected to the second track 102 by a fixing member 4.
[0069] Specifically, the conveying component 3 is located on one side of the track component 1 and includes a second motor 301 and a rotating rod 302 connected sequentially along the X direction. A gear 303 is sleeved on one end of the rotating rod 302 away from the second motor 301, and part of the tooth surface of the gear 303 extends between the first track 101 and the second track 102.
[0070] Specifically, the torque detector 5 includes an input terminal 6 and an output terminal 7. The input terminal 6 is connected to the second motor 301 to detect the torque of the gear 303, and the output terminal 7 is electrically connected to the first motor 201 to control the movement of the slider 203.
[0071] When the tape track is in operation, the tape 8 passes between the first track 101 and the second track 102. The positioning hole on the tape 8 meshes with the gear 303, and the rotation of the gear 303 drives the tape 8 forward. When the width of the tape 8 is greater than the width of the track assembly 1 (the width of the track assembly 1 refers to the distance between the first track 101 and the second track 102), the friction between the track assembly 1 and the tape 8 will prevent the tape 8 from moving. At this time, the torque detector 5 detects that the torque of the gear 303 has increased, and then the torque detector 5 sends a width adjustment command to the width adjustment assembly 2. The first motor 201 of the width adjustment assembly 2 adjusts the slider 203 to move in the X direction by rotating the screw 202, thereby driving the second track 102 to move in the X direction, thus widening the track assembly 1. In this way, the tape 8 is no longer squeezed by the track assembly 1, and the torque of the gear 303 returns to the standard value, preventing damage to the tape 8, thereby avoiding rework of the inspection equipment and improving the accuracy of tape inspection.
[0072] However, it is difficult to adjust the width of the track assembly 1 to a suitable width in a single adjustment. To prevent the tape 8 from being obstructed by the track assembly 1, the width adjustment component 2 often moves the second track 102 a large distance, resulting in an excessively wide track assembly 1. An excessively wide track causes the tape 8 to move more vertically within the track, leading to inaccurate inspection results from the tape inspection equipment when inspecting chips. Therefore, after the first width adjustment, the torque detector 5 sends a narrowing command to the width adjustment component 2. The first motor 201 of the width adjustment component 2 adjusts the slider 203 to move in the opposite direction of the X direction by rotating the screw 202, thereby driving the second track 102 to move in the opposite direction of the X direction, thus narrowing the track assembly 1. However, even a single narrowing adjustment is difficult to adjust the width of the track assembly 1 to a suitable width, often resulting in the second track 102 being moved a large distance, causing the width of the track assembly 1 to be too small, thus again obstructing the forward movement of the tape 8. Therefore, the entire width adjustment component 2 needs to cyclically perform width and narrowing operations until the width of the track component 1 is adjusted to a suitable width. It should be noted that in one cycle, the width adjustment distance is always greater than the narrowing distance. Furthermore, with each additional width or narrowing operation, the movement distance of the second track 102 decreases relative to the previous one. In this way, the width adjustment of the track component 1 can be completed, achieving automatic adjustment of the tape track width, thereby reducing the probability of damage to the tape 8, avoiding rework caused by the tape machine, reducing material and manpower waste, and improving machine utilization and the accuracy of detection results. Further, to ensure that the tape 8 is not damaged, a torque protection value is set in the torque detector 5. When the torque of the gear 303 does not reach this value, the width adjustment component 2 automatically adjusts the width of the track component 1; when the torque of the gear 303 reaches this value, the machine stops and prompts personnel to confirm the condition of the track component 1 and the tape 8.
[0073] To more clearly demonstrate the automatic adjustment process of the width of the track assembly 1, the torque variation of the gear was recorded in this embodiment. The recording results can be found in [link to documentation]. Figure 4 , Figure 4This diagram illustrates the torque variation of gear 303 during automatic adjustment of the tape track for tape inspection according to this invention, in one example. The vertical axis represents the torque value of gear 303, and the horizontal axis represents the automatic adjustment status of the track assembly 1. First, the standard torque parameter value of gear 303 is set to 0.4. When the track assembly 1 encounters an anomaly (i.e., the tape 8 is obstructed), the torque of gear 303 gradually increases to 0.8. At this time, the track assembly 1 automatically widens, performing a first widening adjustment of 0.2 mm. Subsequently, the torque value of gear 303 quickly returns to the standard value of 0.4. Next, the widening assembly 2 automatically narrows, performing a first narrowing adjustment of 0.15 mm. At this time, the torque value of gear 303 increases again to 0.6. The widening assembly 2 then automatically widens again, performing a second widening adjustment, this time with a smaller distance of 0.1 mm than the first adjustment. Subsequently, the torque value of the gear 303 quickly returns to the standard value of 0.4. The width adjustment component 2 automatically narrows again, performing a second narrowing adjustment, this time with a smaller distance of 0.08mm than the first narrowing. At this time, the torque value of the gear 303 increases again to 0.5. The width adjustment component 2 automatically widens again, performing a third widening adjustment, this time with a smaller distance of 0.05mm than the second widening. Subsequently, the width of the width adjustment component 2 is adjusted to a suitable width, and the torque value of the gear 303 quickly returns to the standard value of 0.4. Thus, after three widening adjustments and two narrowing adjustments, the automatic adjustment of the width of the width adjustment component 2 is completed. In other embodiments, the number of widening and narrowing adjustments can also be more, such as five widening and four narrowing adjustments, six widening and five narrowing adjustments, or eight widening and seven narrowing adjustments. The more widening and narrowing adjustments, the higher the adjustment accuracy.
[0074] As an example, a first coupling 204 is provided between the screw 202 and the first motor 201, and a second coupling 304 is provided between the rotating rod 302 and the second motor 301.
[0075] As an example, the fixing member 4 includes a fixing part 401 and a connecting part 402 located at both ends of the fixing part 401 and extending in a vertical direction. The fixing part 401 is fixedly connected to the slider 203, and the connecting part 402 is fixedly connected to the second slide rail 13.
[0076] As an example, the connecting part 402 is connected to the second slide rail 13 by a fixing screw 9. The connecting part 402 is provided with a screw hole groove (not shown), and the fixing screw 9 passes through the second slide rail 13 and is threadedly connected to the screw hole groove.
[0077] As an example, the tape track further includes a U-shaped fixing block 10 and a laser sensor 11. The U-shaped fixing block 10 is sleeved on the outside of the first track 101 and includes a vertical portion 1001 and a horizontal portion 1002 located at both ends of the vertical portion 1001 and extending along the X direction. The laser sensor 11 includes a laser emitting portion 1101 and a laser receiving portion 1102 disposed opposite to each other. The laser emitting portion 1101 is located on the horizontal portion 1002 above the first track 101, and the laser receiving portion 1102 is located on the horizontal portion 1002 below the first track 101. The laser sensor 11 can determine whether the tape 8 is moving normally by measuring the time interval between the laser signals received by the laser receiving portion 1102. This is because when the tape 8 is moving normally, the laser emitted by the laser emitting portion 1101 can be transmitted to the laser receiving portion 1102 through the positioning holes on the tape 8, and the laser receiving portion 1102 receives the laser signals at a fixed time interval. However, when the tape 8 stops moving, the laser emitted by the laser emitting unit 1101 will continue to pass through the positioning hole, or will not be able to be transmitted to the laser receiving unit 1102 through the tape 8. That is, the fixed time interval at which the laser receiving unit 1102 receives the laser signal will change. Adding the laser sensor 11 can assist the torque detector 5 in detecting the movement of the tape 8 and avoid accidents.
[0078] As an example, the number of laser sensors 11 is one or more, the number of U-shaped fixing blocks 10 is consistent with the number of laser sensors 11, the length of the first slide rail 12 is relatively long, and multiple laser sensors 11 can detect the movement of the tape 8 at various positions on the first slide rail 12, thereby increasing the detection accuracy.
[0079] As an example, the first motor 201 is provided with a first connection interface 205, which is electrically connected to the output terminal 7.
[0080] As an example, the second motor 301 is provided with a second connection interface 305, which is electrically connected to the input terminal 6.
[0081] As an example, the tape track also includes a slide rail assembly located below the track assembly 1. The slide rail assembly includes a first slide rail 12 and a second slide rail 13 arranged opposite to each other. Both the first slide rail 12 and the second slide rail 13 extend along the X direction. A first slider 14 is sleeved on the first slide rail 12, and a second slider 15 is sleeved on the second slide rail 13. The first slider 14 and the second slider 15 are respectively fixed to both ends of the second track 102. The second slide rail 13 is longer. The slide rail assembly can assist the width adjustment assembly 2 in moving the position of the second track 102.
[0082] As an example, the tape track also includes a feed roller and a take-up roller (not shown) located at both ends of the track assembly 1. The tape 8 starts from the feed roller, passes through the track assembly 1, and is finally collected by the take-up roller.
[0083] In summary, the tape feeding track for tape feeding inspection of this utility model includes a track assembly, a width adjustment assembly, a conveying assembly, and a torque detector. The track assembly includes a first track and a second track arranged opposite to each other. The width adjustment assembly is located below the track assembly and includes a first motor and a screw connected sequentially along the X-direction, from the first track to the second track. A slider is fitted onto the screw, and the slider is fixedly connected to the second track by a fixing member. The conveying assembly is located on one side of the track assembly and includes a second motor and a rotating rod connected sequentially along the X-direction. A gear is fitted onto the end of the rotating rod away from the second motor, and part of the gear's tooth surface extends between the first and second tracks. The torque detector includes an input end and an output end. The input end is connected to the second motor to detect the gear torque, and the output end is electrically connected to the first motor to control the movement of the slider. The tape feeding track for tape feeding inspection of this utility model can avoid rework in tape feeding inspection equipment, improve the accuracy of tape feeding inspection, and increase the utilization rate of the machine. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.
