Description

Technical Field

[0001] This utility model relates to the field of semiconductor chip tape and reel processing, and in particular to a tape winding device. Background Technology

[0002] In the semiconductor chip taping or processing, the tape winding device is a crucial piece of equipment for continuous tape winding. Its main function is to wind the processed tape onto a reel for subsequent use. In common technologies, the tape winding device typically needs to secure the tape to the reel's winding shaft to ensure smooth winding. However, common technologies have some shortcomings in tape securing:

[0003] Fixing operations rely on manual labor: When fixing the material strip to the roll shaft, the commonly used material strip winding device often requires manual application of tape or other manual operations. This is not only inefficient, but also prone to inaccurate fixing due to human factors.

[0004] Insufficient fixing strength: In common technologies, the material strip is usually connected to the roll shaft only by single-sided tape or simple insertion. This fixing method sometimes causes the material strip to loosen during the winding process due to insufficient adhesion, which affects production efficiency and product quality.

[0005] Therefore, the working efficiency and winding effect of existing material strip winding devices cannot meet expectations. Summary of the Invention

[0006] To address the problems of excessive tape winding and insufficient fixing strength in existing technologies, the purpose of this utility model is to provide a highly efficient, robust, and automated tape winding device.

[0007] To achieve the above-mentioned utility model objectives, one embodiment of this utility model provides a tape winding device, comprising:

[0008] A material reel, with a winding shaft at its center, is used to wind the material strip.

[0009] The first labeling assembly includes a first labeling disc, which is used to pick up the first tape and rotate against the roll shaft, thereby attaching the first tape to one side of the tape and the roll shaft simultaneously by rotation and pressure.

[0010] The second labeling assembly includes a second labeling disc, which is used to pick up the second tape and rotate against the roll shaft, thereby attaching the second tape to the other side of the tape and the roll shaft simultaneously by rotation and pressure.

[0011] As a further improvement of this utility model, the first labeling disc and the second labeling disc are both rotated clockwise or counterclockwise to attach the first tape and the second tape to opposite sides of the material strip and the roll shaft respectively, with the first tape and the second tape adhering to opposite sides of the material strip at the same position.

[0012] As a further improvement of this utility model, the roll shaft is provided with a plurality of holes for inserting the strip;

[0013] The strip winding device further includes an insertion mechanism for inserting the strip into the opening.

[0014] As a further improvement of this utility model, after the material strip is inserted into the hole, the first labeling component and the second labeling component work alternately so that the first tape and the second tape are sequentially attached to the material strip and the roll.

[0015] As a further improvement of this utility model, the inserting mechanism includes an inserting nozzle and a forward driving part. The inserting nozzle extends in the inserting direction, and the forward driving part drives the material strip to be ejected from the inserting nozzle and move along the inserting direction.

[0016] The strip winding device further includes a first moving mechanism, which moves the insert nozzle into the strip reel and aligns it with the opening.

[0017] As a further improvement of this utility model, the tape winding device further includes:

[0018] The second moving mechanism drives the first labeling disc to move closer to or away from the roll shaft along a first direction;

[0019] A third moving mechanism drives the second labeling disc to move closer to or away from the roll shaft along the first direction;

[0020] A fourth moving mechanism drives the material reel to move along a second direction, wherein the first direction is perpendicular to the second direction;

[0021] Along the second direction, the material reel is disposed between the first labeling component and the second labeling component.

[0022] As a further improvement of this utility model, both the first labeling component and the second labeling component include a label dispensing mechanism. The label dispensing mechanism includes a tape roll, a conveying section, and a receiving roll. The tape roll outputs the first tape or the second tape. Waste of the first tape or the second tape is recycled by the receiving roll via the conveying section. The first labeling disc or the second labeling disc obtains the tape at the conveying section.

[0023] As a further improvement of this utility model, both the first labeling component and the second labeling component include a label picking mechanism. The label picking mechanism includes a moving part, which drives the first labeling disk or the second labeling disk to reciprocate in the direction of approaching or moving away from the conveying part.

[0024] As a further improvement of this utility model, both the first labeling component and the second labeling component include a rotation drive unit. Both the first labeling disc and the second labeling disc are configured as vacuum rotating wheels. The rotation drive unit drives the vacuum rotating wheels to rotate. A plurality of vacuum suction holes are provided on the circumferential surface of the vacuum rotating wheels. The vacuum suction holes adsorb the side of the first tape or the second tape that is not covered with adhesive.

[0025] As a further improvement of this utility model, a flexible part is provided on the vacuum rotating wheel. The first labeling disc and the second labeling disc abut against the roll shaft by the deformation of the flexible part, so that the first tape and the second tape adhere tightly to the roll shaft and the material strip.

[0026] Compared with commonly used technologies, this utility model has the following advantages: The first and second labeling discs of the tape winding device respectively pick up the first and second adhesive tapes and attach them sequentially to both sides of the tape and the winding shaft by means of rotation and pressure. This greatly improves the automation level and production efficiency of the fixing process and forms a double-sided fixing structure, which significantly enhances the connection between the tape and the winding shaft and effectively prevents the tape from loosening during the winding process. This provides an efficient, strong and automated winding solution for the large-scale production of semiconductor chip tape or processing. Attached Figure Description

Detailed Implementation

[0040] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0041] It should be understood that terms such as “above,” “over,” “below,” and “under” used herein to indicate spatial relative position are for illustrative purposes to describe the relationship of one unit or feature relative to another unit or feature as shown in the accompanying drawings. The terms “spatial relative position” may be intended to include different orientations of the equipment in use or operation other than those shown in the figures.

[0042] This embodiment provides a material strip winding device that improves the efficiency and stability of material strip fixing through automated design.

[0043] The tape winding device 100 in this embodiment, such as Figure 1 As shown, it includes a material reel 10, a first labeling component 20, and a second labeling component 30.

[0044] The material reel 10 winds the material strip 12, and the first labeling component 20 and the second labeling component 30 are used to attach the tape to both sides of the material strip 12 to ensure that the material strip 12 is firmly fixed.

[0045] like Figures 1 to 3 As shown, the material reel 10 is a disc-shaped component, and a winding shaft 11 is provided at the center of the material reel 10. The winding shaft 11 is a cylindrical structure that can support the material strip 12 and drive it to rotate.

[0046] The first labeling assembly 20 includes a first labeling disc 233, and the second labeling assembly 30 includes a second labeling disc 333. These two labeling discs are circular components respectively disposed on both sides of the material roll 10. The first labeling disc 233 and the second labeling disc 333 are driven by a drive structure and can rotate flexibly. At the same time, they can approach or abut against the material roll 11 during the application process to apply the tape to the target position.

[0047] The first labeling disc 233 is used to pick up the first tape 21 and rotate against the roll shaft 11, so that the first tape 21 is simultaneously attached to one side of the material strip 12 and the roll shaft 11 by rotation and pressure; the second labeling disc 333 is used to pick up the second tape 31 and rotate against the roll shaft 11, so that the second tape 31 is simultaneously attached to the other side of the material strip 12 and the roll shaft 11 by rotation and pressure.

[0048] The first label tray 233 and the second label tray 333 adhere to the adhesive tape on their surfaces, firmly adhering to the non-adhesive side of the tape to ensure that the tape will not fall off or shift before application.

[0049] The working process of the first labeling tray 233 and the second labeling tray 333 can both be divided into three steps: picking up the tape, bringing it close to the roll shaft 11, and rotating to attach it.

[0050] Taking the first labeling reel 233 as an example, firstly, the first labeling reel 233 obtains the first adhesive tape 21 from the tape supply mechanism and adheres to the non-adhesive side of the first adhesive tape 21. Next, driven by a robotic arm or moving mechanism, the first labeling reel 233 approaches the roll spool 11 until the edge of the first labeling reel 233 abuts against the surface of the roll spool 11. Finally, the first labeling reel 233 and / or the roll spool 11 begin to rotate, and through this rotational motion, the adhesive side of the first adhesive tape 21 is attached to the tape 12 and the roll spool 11. In other words, either the first labeling reel 233 or the roll spool 11 can rotate independently, driving the other to rotate, or both can rotate synchronously and actively.

[0051] In this process, the first labeling reel 233 is responsible for attaching the tape to one side of the material strip 12 and the roll spool 11, while the second labeling reel 333 is responsible for attaching it to the other side of the material strip 12 and the roll spool 11. Through the coordinated work of the first labeling reel 233 and the second labeling reel 333, the material strip 12 is fixed to the roll spool 11 on both sides, forming a stable connection.

[0052] The first labeling reel 233 and the second labeling reel 333 apply the tape using a combination of rotation and pressure. During rotation, they maintain slight contact with the roll spool 11, while the pressure ensures the tape adheres tightly to the surfaces of the strip 12 and the roll spool 11. The rotational motion ensures even distribution of the tape, preventing wrinkles or gaps; while the pressure increases the adhesion between the tape and the strip 12, resulting in a more secure fixation and enhanced stability of the strip 12.

[0053] Furthermore, the edges of the first labeling reel 233 and the second labeling reel 333 are made of a flexible material that deforms slightly under pressure, further conforming to the surfaces of the tape 12 and the roll 11. This flexible design compensates for minor surface unevenness, ensuring complete and consistent tape application.

[0054] Through the double-sided application design of the first labeling component 20 and the second labeling component 30, the tape 12 is firmly fixed to the roll spool 11 by the first adhesive tape 21 and the second adhesive tape 31. This double-sided fixing method greatly enhances the connection strength between the tape 12 and the roll spool 11. Even under high-speed rotation or long-term winding, the tape 12 will not easily come loose, ensuring the smooth progress of the winding process.

[0055] The application process of the first tape 21 and the second tape 31 is automatically completed by the first labeling component 20 and the second labeling component 30, eliminating the need for manual tape application and significantly improving operational efficiency. It is particularly suitable for production scenarios that require rapid winding.

[0056] In this embodiment, the first labeling disc 233 and the second labeling disc 333 are rotated clockwise or counterclockwise to attach the first tape 21 and the second tape 31 to opposite sides of the material strip 12 and the roll spool 11, respectively. The first tape 21 and the second tape 31 are attached to opposite sides of the material strip 12 at the same position.

[0057] After picking up the first tape 21 and the second tape 31, the first labeling reel 233 and the second labeling reel 333 will select an appropriate rotation direction according to a preset program. For example, when attaching to one side of the material tape 12, the first labeling reel 233 may rotate clockwise, so that the adhesive side of the tape gradually adheres to the material tape 12 and the roll spool 11; while when attaching to the other side, the second labeling reel 333 may rotate counterclockwise (e.g., ...). Figures 10 to 11As shown), or when applying the tape from the middle, first rotate clockwise, then counterclockwise (as shown). Figures 7 to 9 (As shown), to adapt to different angles and positions. This flexible rotating design ensures uniform and firm tape application.

[0058] Specifically, the first tape 21 and the second tape 31 are adhered to opposite sides of the same position on the material strip 12, forming a "sandwich" type fixing structure, such as... Figure 12 As shown. This design tightly wraps the tape 12 from both sides with adhesive tape, significantly improving the connection strength between the tape 12 and the roll 11. Even if the tape 12 is subjected to large tension during the winding process, it can avoid loosening or displacement, ensuring the stability and reliability of the winding process.

[0059] like Figure 3 As shown, the roll spool 11 has several holes 111 for inserting the strip 12. The holes 111 are used for initial fixing of the strip 12. These holes 111 are distributed on the circumferential surface of the roll spool 11, and their size and shape match the ends of the strip 12. The function of the holes 111 is to receive the ends of the strip 12 before winding begins, so that it is firmly locked on the roll spool 11, preventing the strip 12 from slipping or falling off before the adhesive tape is applied.

[0060] like Figure 1 and 4 As shown, the strip winding device 100 also includes a material insertion mechanism 40, which is used to insert the end of the strip 12 into the hole 111.

[0061] The design of the insertion mechanism 40 fully considers the flexibility and bendability of the strip 12, ensuring that the strip 12 is not damaged during the insertion process, while quickly completing the insertion action and improving production efficiency.

[0062] After the material tape 12 is inserted into the hole 111, the first labeling component 20 and the second labeling component 30 work alternately to attach the first adhesive tape 21 and the second adhesive tape 31 to the material tape 12 and the roll 11 in sequence.

[0063] like Figures 7 to 9 As shown, the first labeling component 20 first applies the first adhesive tape 21, and then... Figures 10 to 11 As shown, the second labeling component 30 attaches the second adhesive tape 31.

[0064] The first labeling assembly 20 is activated first. The first labeling disc 233 picks up the first adhesive tape 21 and rotates against the roll spool 11, attaching the first adhesive tape 21 to one side of the material strip 12 and the roll spool 11. After completion, the first labeling disc 233 retracts. Subsequently, the second labeling assembly 30 is activated. The second labeling disc 333 picks up the second adhesive tape 31 and rotates against the roll spool 11, attaching the second adhesive tape 31 to the other side of the material strip 12 and the roll spool 11. Finally, the second labeling disc 333 retracts, completing the application. This alternating operation ensures the accuracy of the adhesive tape application.

[0065] The design of the material insertion mechanism 40, the first labeling component 20 and the second labeling component 30 working together improves the operating efficiency of the device, shortens the double-sided tape application time, and meets the needs of high-efficiency production.

[0066] The insertion mechanism 40 in this embodiment includes an insertion nozzle 41 and a forward drive unit 42. The insertion nozzle 41 extends in the insertion direction, and the forward drive unit 42 drives the material strip 12 to be ejected from the insertion nozzle 41 and move along the insertion direction, thus cooperating to complete the insertion task of the material strip 12.

[0067] The insert nozzle 41 adopts a duckbill structure, which is formed by two clamping plates of a certain length. It can be opened or clamped. When opened, one of the clamping plates can guide the end of the material strip 12 to move along the insertion direction. After it moves into place, the other clamping plate clamps the material strip 12.

[0068] The forward drive unit 42 is the power source for the insertion mechanism 40, responsible for driving the material belt 12 to move along the insertion direction and eject it from the insertion nozzle 41. The forward drive unit 42 is usually driven by a motor or cylinder, which can precisely control the moving speed and distance of the material belt 12 to ensure accurate insertion into the hole 111.

[0069] The material strip winding device 100 also includes a first moving mechanism, which moves the insert nozzle 41 into the material roll 10 and aligns it with the hole 111.

[0070] like Figure 1 As shown, a base 43 is provided below the inserting mechanism 40. The base 43 is fixed on the first moving mechanism, and the first moving mechanism drives the base and the inserting mechanism 40 to move in the left and right directions.

[0071] The first moving mechanism adopts a linear guide or slider structure to support the flexible movement of the insert nozzle 41 in three-dimensional space, ensuring precise alignment.

[0072] During operation, the material strip 12 is first moved, and the insertion mechanism 40 clamps the end of the material strip 12. Then, the first moving mechanism moves the insertion nozzle 41 to a position aligned with the hole 111, and then the material strip 12 is inserted into the hole 111. After insertion, the insertion nozzle 41 returns to its original position. The entire process is automatically controlled, requiring no manual intervention, and is highly precise, significantly improving the success rate and efficiency of material strip 12 insertion.

[0073] Furthermore, the tape winding device 100 also includes a second moving mechanism 50, a third moving mechanism, and a fourth moving mechanism 60, some of which are as follows: Figure 1 and 2 As shown.

[0074] The second moving mechanism 50 drives the first labeling disc 233 to move closer to or further away from the roll spool 11 along a first direction T1 (e.g., horizontal direction). When tape needs to be applied, the second moving mechanism 50 pushes the first labeling disc 233 toward the roll spool 11, ensuring accurate contact with the surface of the roll spool 11. After application, the second moving mechanism 50 retracts the first labeling disc 233 back to its original position.

[0075] The third moving mechanism drives the second labeling disc 333 to move closer to or further away from the roll shaft 11 along the first direction T1. Similar to the second moving mechanism 50, the third moving mechanism is driven along the same first direction T1 to complete the application of the second adhesive tape 31. The second moving mechanism 50 and the third moving mechanism operate independently and are spaced a certain distance apart to ensure that the application process does not interfere with each other.

[0076] The fourth moving mechanism 60 drives the material reel 10 to move along the second direction T2 (e.g., the vertical direction), where the first direction T1 is perpendicular to the second direction T2. ​​The movement of the material reel 10 is primarily for position adjustment to align with the inserting mechanism 40 or the first labeling assembly 20 and the second labeling assembly 30. For example, during inserting the material, the material reel 10 may need to move up and down to align with the insert nozzle 41; when applying adhesive tape, its position needs to be precisely adjusted to coordinate with the movements of the first labeling reel 233 and the second labeling reel 333.

[0077] The first direction T1 is perpendicular to the second direction T2. ​​This ensures the independent movement of each component in three-dimensional space. For example, the second moving mechanism 50 is driven above the third moving mechanism, the fourth moving mechanism 60 is located to the left, the first labeling disc 233 and the second labeling disc 333 move left and right in the horizontal direction, while the material reel 10 moves up and down or makes fine adjustments in the vertical direction, which avoids interference and improves operational flexibility.

[0078] Along the second direction T2, the material reel 10 is positioned between the first labeling component 20 and the second labeling component 30, forming a symmetrical layout. For example... Figure 1As shown, this layout allows the two labeling discs to label the material reel 10 from the top and bottom respectively, optimizing the spatial layout and improving operational efficiency.

[0079] like Figure 5 As shown, both the first labeling component 20 and the second labeling component 30 include a label dispensing mechanism 32, which includes a tape roll 321, a conveyor 322, and a take-up roll 323.

[0080] The tape roll 321 is wound with either the first tape 21 or the second tape 31, serving as the source of tape supply. It is usually mounted on a rotatable shaft, and the tape gradually unwinds as the first labeling disc 233 or the second labeling disc 333 picks up a label.

[0081] The conveyor section 322 is the transition area for the tape from the tape roll 321 to the first labeling reel 233 or the second labeling reel 333. It is usually composed of rollers or guide rails to ensure that the tape is transported smoothly and without wrinkles to the labeling position of the first labeling reel 233 or the second labeling reel 333.

[0082] The take-up roll 323 is used to recycle waste materials, such as the release paper on the back of the tape. After the tape is removed from the first label tray 233 or the second label tray 333, the waste material is rolled up by the take-up roll 323 via the conveyor section 322 to keep the work area clean. The waste material of the first tape 21 or the second tape 31 is recycled by the take-up roll 323 via the conveyor section 322.

[0083] The first labeling tray 233 or the second labeling tray 333 picks up the tape at the conveyor section 322. The adsorption device of the first labeling tray 233 or the second labeling tray 333 is precisely aligned with the position of the tape on the conveyor section 322, and the tape is fixed by vacuum adsorption.

[0084] The structure of the bidding mechanism 32 ensures a continuous and stable supply of tape, meeting the needs of automated production.

[0085] like Figure 5 and 6 As shown, both the first labeling component 20 and the second labeling component 30 include a label picking mechanism 33. The label picking mechanism 33 includes a moving part 331, which drives the first labeling disk 233 or the second labeling disk 333 to reciprocate in the direction of approaching or moving away from the conveying part 322.

[0086] The moving part 331 typically consists of a linear guide, a slider, and a drive motor, capable of driving the first labeling disc 233 or the second labeling disc 333 to reciprocate in a direction approaching or moving away from the conveyor part 322. When a label needs to be picked up, the moving part 331 moves the first labeling disc 233 or the second labeling disc 333 to the tape position of the conveyor part 322; after the label is picked up, the first labeling disc 233 or the second labeling disc 333 returns to the position where the tape is to be applied.

[0087] exist Figure 6 In this design, the label-taking mechanism 33 of the first labeling assembly 20 includes a belt drive 332, one end of which is a first labeling disc 233. Similarly, the label-taking mechanism 33 of the second labeling assembly 30 includes a belt drive 332, one end of which is a second labeling disc 333. The pulley of the belt drive 332 is driven to rotate by a rotation drive 334, and the moving part 331 drives the entire belt drive 332 to move linearly. This allows either the first labeling disc 233 or the second labeling disc 333 to quickly switch between the tape supply point and the labeling point, shortening the operation cycle time and improving production efficiency.

[0088] like Figure 6 As shown, both the first labeling component 20 and the second labeling component 30 include a rotation drive unit 334. Both the first labeling disk 233 and the second labeling disk 333 are configured as vacuum rotating wheels. The rotation drive unit 334 drives the vacuum rotating wheels to rotate. Multiple vacuum suction holes 3331 are provided on the circumferential surface of the vacuum rotating wheels. The vacuum suction holes 3331 adsorb the side of the first adhesive tape 21 or the second adhesive tape 31 that is not glued.

[0089] The rotation drive unit 334 is a servo motor or a stepper motor, which can drive the vacuum rotating wheel to rotate clockwise or counterclockwise at a precise angle via the belt drive unit 332. By precisely controlling the rotation speed and direction, the rotation drive unit 334 ensures that the vacuum rotating wheel rotates synchronously with the roll shaft 11 during the application process, thereby achieving uniform application of the tape.

[0090] The circumference of the vacuum rotating wheel is covered with multiple vacuum suction holes 3331. These vacuum suction holes 3331, through the negative pressure generated by a vacuum pump or vacuum generator, can firmly adsorb the non-adhesive side of the tape. Before application, the vacuum rotating wheel first rotates to the tape supply position to generate negative pressure to suck up the tape; then, it rotates to the vicinity of the roll spool 11, and through rotation and pressure, it adheres the adhesive side of the tape to the tape 12 and the roll spool 11, and then stops generating negative pressure.

[0091] Furthermore, a flexible part is provided on the vacuum rotating wheel. The contact between the first labeling disc 233 and the second labeling disc 333 and the roll shaft 11 is achieved by the deformation of the flexible part, so that the first tape 21 and the second tape 31 are tightly attached to the roll shaft 11 and the material strip 12.

[0092] The flexible part is usually made of elastic materials such as rubber and silicone, and covers the circumferential surface of the vacuum rotating wheel. Its main function is to deform and fit the surfaces of the roll 11 and the tape 12 during the application process. This deformation can compensate for the slight unevenness of the surface of the roll 11 or the tape 12, ensure that the tape and the contact surface are fully bonded, and avoid poor local adhesion.

[0093] The elastic properties of the flexible section allow for more even pressure application during the application process, which helps to enhance the adhesion between the tape, the material strip 12, and the roll 11. This design significantly improves the adhesion of the tape and reduces the risk of the material strip 12 coming loose during the winding process.

[0094] In addition, the flexible part buffers the impact force when pressed, preventing the material strip 12 from being damaged by impact or stress when the first labeling disc 233 and the second labeling disc 333 come into contact with the roll shaft 11. It is especially suitable for flexible or fragile material strip 12 materials.

[0095] like Figures 7 to 12 As shown, the process of applying the first tape 21 and the second tape 31 is illustrated.

[0096] exist Figure 7 In the middle, the first labeling disc 233 adsorbs the middle position of the first adhesive tape 21 and abuts against the roll shaft 11.

[0097] from Figures 7 to 8 During the process, the first labeling disc 233 rotates counterclockwise to attach the upper part of the first tape 21 to the roll 11.

[0098] from Figures 8 to 9 During the process, the first labeling disc 233 rotates clockwise to attach the lower half of the first adhesive tape 21 to the upper surface of the material tape 12.

[0099] exist Figure 9 In the middle, after applying the first label plate 233 and the first tape 21, we prepared to leave.

[0100] exist Figure 10 In the middle, the edge of the second labeling disc 333 adsorbs the second tape 31 and abuts against the roll shaft 11.

[0101] from Figures 10 to 11 During the process, the second labeling disc 333 rotates counterclockwise, sequentially attaching the second adhesive tape 31 to the lower surfaces of the roll 11 and the material strip 12. Figure 11 The second plate, 333, is ready to be withdrawn.

[0102] from Figures 7 to 11 During the process of change, the roll shaft 11 always rotates in coordination with the first labeling disc 233 and the second labeling disc 333.

[0103] exist Figure 12 In the process, the first tape 21 and the second tape 31 are attached to opposite sides of the same position on the material tape 12, forming a "sandwich" type fixing structure, which greatly improves the connection strength compared to single-sided attachment.

[0104] Compared with the prior art, this embodiment has the following beneficial effects:

[0105] The first labeling disc 233 and the second labeling disc 333 of the tape winding device 100 respectively pick up the first tape 21 and the second tape 31, and attach the tapes to both sides of the tape 12 and the winding shaft 11 by means of rotation and pressure. This greatly improves the automation level and production efficiency of the fixing process, and forms a double-sided fixing structure, which significantly enhances the connection between the tape 12 and the winding shaft 11, effectively preventing the tape 12 from loosening during the winding process. This provides an efficient, strong and automated winding solution for the large-scale production of semiconductor chip tape or processing.
