Description

Technical Field

[0001] This invention relates to the field of flip-chip film packaging process equipment technology, specifically to an automatic traction tape splicing device and method in flip-chip film packaging process. Background Technology

[0002] Flip-chip thin-film packaging is a crucial process in electronic device manufacturing, and traction belts play an irreplaceable role in material transport during this process. In actual production, traction belts need to be cut and then spliced ​​according to process requirements to meet the length requirements for continuous production.

[0003] Currently, the splicing of traction belts is mostly done manually. However, manual operation has many drawbacks: First, positioning errors are unavoidable in manual operation, resulting in low splicing accuracy of the traction belt and affecting the stability of subsequent flip-chip encapsulation processes. Second, manual contact with the traction belt can easily cause contamination or physical damage, reducing the quality of the traction belt. Third, manual splicing is inefficient, consuming a lot of manpower and time, and is difficult to match the high-speed production requirements of modern production lines.

[0004] Furthermore, a search revealed existing technologies that already disclose related splicing devices, such as the splicing device with patent publication number CN219929123U. This patent, through the cooperation of a material tape channel, a transfer mechanism, and a drive mechanism, enables the material tape to be accurately placed on the material tape channel and to move stably on it. Then, using a positioning mechanism, a trimming mechanism, and splicing components, the material tape located on the material tape channel is positioned and trimmed, and the rear end of the previous material tape and the front end of the subsequent material tape are connected at a predetermined correct spacing without misalignment. The entire process requires no manual intervention, thus achieving automatic splicing of the material tape. However, this patent is only applicable to the connection of ordinary semiconductor material tapes. Its splicing process can only achieve single-sided adhesive splicing, and the joint bonding strength and flatness are insufficient, failing to meet the requirements of high-speed and stable conveying of the traction tape in flip-chip film packaging processes. Therefore, this disclosed technology cannot be adapted to the usage requirements of flip-chip film packaging production lines. Summary of the Invention

The positioning cylinder is used to drive the positioning pin through the hole on the traction belt to achieve positioning of the traction belt. The cutting table, the upper surface adhesive application table, the lower surface adhesive application table, the punching table, and the pressure plate are respectively provided with positioning channels.

[0015] This invention also provides an automatic splicing method for traction tape in flip-chip thin-film packaging process, comprising the following steps: S1. The operator places the tape roll on the tape guide unit and pulls one end of the tape to the clamping end of the fixed gripper cylinder for clamping and fixing. The end of the tape after clamping protrudes slightly from the clamping end of the fixed gripper cylinder. S2. After the receiving platform corresponding to the head cutting unit moves to the conveying path under the drive of the hopper cylinder, a front traction belt is conveyed by the conveying mechanism, and the conveying stops when the tail end of the traction belt is about to enter the cutting table surface; then the positioning cylinder pushes the positioning pin to insert into the hole on the traction belt to achieve the initial positioning of the front traction belt, ensuring that the tail end of the traction belt is left 0.05mm outside the cutting table. S3. Use the stabilizing cylinder in the tail cutting unit to push the positioning plate to press and position the front traction belt, and then use the cutting cylinder in the tail cutting unit to push the cutting blade to cut the tail end of the front traction belt; the cut waste can fall into the second waste box corresponding to the tail cutting unit under its own weight. S4. After the front traction belt is cut, each module is reset and the material conveying mechanism is started to convey the front traction belt. At the same time, the receiving platform corresponding to the tail cutting unit is moved to the material conveying path by the working of the hopper cylinder, and then a rear traction belt is conveyed by the material conveying mechanism. The conveying stops when the head end of the traction belt slightly exceeds the table surface of the cutting table. Then, the positioning cylinder pushes the positioning pin to insert into the hole on the traction belt to achieve the initial positioning of the rear traction belt and ensure that the head end of the traction belt extends precisely 0.05mm outside the cutting table. S5. Use the stabilizing cylinder in the head cutting unit to push the positioning plate to press and position the rear traction belt, and then use the cutting cylinder in the head cutting unit to push the cutting blade to cut the head end of the rear traction belt; the cut waste can fall into the second waste box corresponding to the head cutting unit under its own weight. S6. After the rear traction belt is cut, each module is reset and the material conveying mechanism is started to transport the rear traction belt, so that the head of the rear traction belt and the tail of the front traction belt are connected at the tape unit on the upper surface; after the connection is completed, the positioning cylinder pushes the positioning pin into the hole on the traction belt to achieve stable connection of the two traction belts. S7. The first retracting cylinder drives the movable gripper cylinder in the upper surface tape application unit to pull the tape located at the clamping end of the fixed gripper cylinder, so that the tape segment is positioned above the joint of the two traction belts; and the second lifting cylinder and the first lifting cylinder simultaneously perform the retraction operation, so that while the lower surface tape application table presses and positions the two traction belts, the tape segment between the fixed gripper cylinder and the movable gripper cylinder can be attached to the upper surface of the joint of the two traction belts. S8. Driven by the combined action of the Y-axis cylinder and Z-axis cylinder in the upper surface tape application unit, the roller smooths and removes air bubbles from the tape on the upper surface of the joint between the two traction belts; then the tape is cut by the cutting unit in the upper surface tape application unit, thus completing the fixation of the upper surface of the joint between the two traction belts. S9. After the upper surface of the joint of the two traction belts is fixed, each module is reset; the material conveying mechanism is started to convey the traction belt, so that the joint of the two traction belts moves to the tape application unit on the lower surface with the assistance of the fiber optic sensor. At the same time, the positioning pin is pushed into the hole on the traction belt by the positioning cylinder at the bottom of the upper surface tape application table and the punching table, so as to achieve precise movement and positioning of the joint of the two traction belts. S10. The second retracting cylinder drives the moving gripper cylinder in the lower surface tape-attaching unit to pull the tape located at the clamping end of the fixed gripper cylinder, so that the tape segment is placed below the joint of the two traction belts; and the third lifting cylinder pushes and the first lifting cylinder retracts, so that the tape segment between the fixed gripper cylinder and the moving gripper cylinder is attached to the lower surface of the joint of the two traction belts. S11. Driven by the cooperation of the Y-axis cylinder and Z-axis cylinder in the lower surface tape application unit, the roller smooths and removes air bubbles from the tape on the lower surface of the joint of the two traction belts; then the tape is cut by the cutting unit in the lower surface tape application unit to complete the fixation of the lower surface of the joint of the two traction belts. S12. After the lower surface of the joint of the two traction belts is fixed, each module is reset; the material conveying mechanism is started to convey the traction belt, so that the joint of the two traction belts moves to the punching table with the assistance of the fiber optic sensor. At the same time, the positioning cylinder at the bottom of the punching table pushes the positioning pin into the hole on the traction belt to achieve precise positioning of the joint of the two traction belts. S13. The pre-fixed cylinder pushes the stamping unit so that the pressure plate at the bottom of the stamping unit can press and fix the two traction belts; then, the punching cylinder drives the punching part to punch holes in the tape surface at the joint, and the cutting part simultaneously cuts the tape on both sides at the joint. Finally, the punched traction belt is conveyed by the conveying mechanism to complete the splicing of the traction belt.

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: In this invention, the cutting module, surface adhesive module, and punching module work together to complete the cutting, double-sided bonding, and waste punching of the traction tape. Furthermore, the positioning module's positioning constraint throughout the process fundamentally avoids positioning errors caused by manual splicing, effectively improving the splicing accuracy of the traction tape and ensuring the stability of subsequent flip-chip film encapsulation processes. Simultaneously, the automated operation method proposed by this device not only ensures that the splicing and cutting processes can be performed without stopping the machine, but also eliminates traction tape contamination and physical damage caused by manual contact, effectively improving the splicing quality and production efficiency of the traction tape, significantly saving labor and time costs, and better matching the high-speed continuous production requirements of modern flip-chip film encapsulation production lines.

[0017] In this invention, by dividing the cutting work between the tail cutting unit and the head cutting unit, a certain length can be cut off from the tail of the first traction belt and the head of the second traction belt respectively, so that the two traction belts will not overlap during subsequent splicing, thus ensuring the accuracy of splicing alignment.

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification. Example 1

[0033] like Figures 1-12 As shown, this invention provides an automatic splicing device for traction tape in a flip-chip thin-film packaging process, including a frame 1 and a feeding mechanism. The frame 1 includes a table surface and multiple support plates mounted on the table surface. The feeding mechanism includes a front pulling unit and a rear pushing unit, which are respectively located on both sides of the frame 1 and are used to transport the traction tape. Between the rear pushing unit and the front pulling unit, a cutting module 2, a surface adhesive module 3, and a punching module 4 are sequentially arranged on the frame 1, wherein: The cutting module 2 includes a cutting table 21 for placing a traction belt, a tail cutting unit 22 for cutting the tail of a traction belt, and a head cutting unit 23 for cutting the head of a traction belt. Both sides of the cutting table 21 are provided with waste hopper modules 5 corresponding to the tail cutting unit 22 and the head cutting unit 23. The surface adhesive application module 3 includes an upper surface adhesive application platform 31, a lower surface adhesive application platform 32, an upper surface adhesive tape application unit 33, and a lower surface adhesive tape application unit 34. The lower surface adhesive application platform 32 is located above the upper surface adhesive application platform 31 and can move up and down relative to the upper surface adhesive application platform 31 via a first lifting cylinder 6. Both the upper surface adhesive tape application unit 33 and the lower surface adhesive tape application unit 34 include a tape guide unit 35 for guiding the tape, a fixed gripper cylinder 36 for clamping the tape, and a mechanism for pulling the tape. The system includes a movable gripper cylinder 37, a cutting unit 38 for cutting the tape, and a pressure roller unit 39 for smoothing the tape and eliminating air bubbles. The cutting unit 38 includes a cutting cylinder and a cutting blade connected to the output end of the cutting cylinder. The cutting blade may have serrations to facilitate cutting the tape. The fixed gripper cylinder 36 and the movable gripper cylinder 37 each include a cylinder body and a clamping block connected to the cylinder body. The fixed gripper cylinder 36 and the movable gripper cylinder 37 clamp the tape through the clamping block. The punching module 4 includes a punching table 41, a pressure plate 42, a pre-fixing cylinder 43, and a punching unit 44. The pre-fixing cylinder 43 is used to drive the punching unit 44 and the pressure plate 42 to move so that the pressure plate 42 pre-fixes the traction belt. The punching unit 44 is used to punch and trim the tape on the traction belt. The bottom of the cutting table 21, the upper surface adhesive application table 31, and the punching table 41 are all equipped with positioning modules 7. The positioning modules 7 are used to pass through the holes on the traction belt to achieve positioning of the traction belt.

[0034] In summary, the tail cutting unit 22, head cutting unit 23, upper surface tape application unit 33, lower surface tape application unit 34, and punching module 4 are sequentially arranged between the rear pushing unit and the front pulling unit, working together to complete the cutting, double-sided bonding and splicing, and waste material punching of the traction tape. Furthermore, the positioning module 7, through its positioning constraint, fundamentally avoids positioning errors caused by manual splicing, effectively improving the splicing accuracy of the traction tape and ensuring the stability of subsequent flip-chip film encapsulation processes. Simultaneously, this device is equipped with a main controller for automation, eliminating traction tape contamination and physical damage caused by manual contact, effectively improving the splicing quality and production efficiency of the traction tape, significantly saving labor and time costs, and better matching the high-speed continuous production requirements of modern flip-chip film encapsulation production lines.

[0035] As a further step, in combination Figure 1 , Figure 7 and Figure 8 As shown, the tail cutting unit 22 and the head cutting unit 23 have the same structure, both including: a cutting cylinder 24, a guide plate 25, a cutting blade 26, a stabilizing cylinder 27, and a positioning plate 28; the cutting cylinder 24 is fixedly installed on the support plate frame of the platform 1; the guide plate 25 is fixedly connected to the output end of the cutting cylinder 24; the cutting blade 26 is fixedly installed on the bottom of the guide plate 25 and is used to cut the traction belt; the stabilizing cylinder 27 is fixedly installed on the surface of the guide plate 25; the positioning plate 28 is fixedly connected to the output end of the stabilizing cylinder 27 and is used to position the traction belt; a positioning channel 10 is opened through the surface of the positioning plate 28, through which the positioning pin 72 of the positioning module 7 passes. The positioning channel 10 on the surface of the positioning plate 28 is correspondingly set to the positioning channel 10 (not shown) on the cutting table 21. This ensures that after the positioning pin 72 completes the initial positioning, when the positioning plate 28 is pressed down, the positioning pin 72 can be inserted into the positioning channel 10 of the positioning plate 28. This avoids the traction belt from being misaligned or shifted because the positioning pin 72 needs to retract when the positioning plate 28 is pressed and fixed, thereby effectively ensuring the subsequent cutting accuracy of the traction belt.

[0036] The cutting blades 26 of the tail cutting unit 22 and the head cutting unit 23 are arranged in a mirror image. The stabilizing cylinders 27 of the tail cutting unit 22 and the head cutting unit 23 are located between the guide plates 25 of the two cutting units to fix the head or tail end of the traction belt and ensure cutting accuracy. Specifically, the stabilizing cylinder 27 of the tail cutting unit 22 is used to fix the tail end of a traction belt, and the stabilizing cylinder 27 of the head cutting unit 23 is used to fix the head end of a traction belt.

[0037] As a further step, in combination Figure 1 , Figure 4 and Figure 5As shown, the upper surface tape application unit 33 is located between the cutting module 2 and the lower surface tape application unit 34. The upper surface tape application unit 33 also includes a second lifting cylinder 331, a first lifting plate 332, and a first retracting cylinder 333. The second lifting cylinder 331 is fixedly installed on the frame 1. The first lifting plate 332 is fixedly installed on the output end of the second lifting cylinder 331 and can move up and down under the drive of the second lifting cylinder 331. The first retracting cylinder 333 is fixedly installed on the top surface of the lower surface tape application table 32 and is used to drive the movable gripper cylinder 37 of the upper surface tape application unit 33 to slide. The movement direction of the movable gripper cylinder 37 is perpendicular to the conveying direction of the conveying traction belt on the upper surface tape application table 31, so as to ensure that the tape can completely cover the splice of the front and rear traction belts.

[0038] It is worth noting that the movable gripper cylinder 37 in the upper surface tape application unit 33 is slidably disposed on the top of the lower surface tape application table 32. The tape guide unit 35, the fixed gripper cylinder 36, and the cutting unit 38 in the upper surface tape application unit 33 are all fixedly mounted on the first lifting plate 332, and the cutting blade of the cutting unit 38 is located between the fixed gripper cylinder 36 and the movable gripper cylinder 37, and can move in the vertical direction. Specifically, before pulling the tape, it is necessary to ensure that the tape surface is higher than the splice of the traction belt; therefore, by driving the movement of the first lifting plate 332 through the second lifting cylinder 331, the tape end held by the fixed gripper cylinder 36 can be higher than the splice of the traction belt; and in order to meet the pulling of the tape, the first lifting cylinder 6 needs to work to drive the lower surface tape application table 32 to move, ensuring that the movable gripper cylinder 37 on the lower surface tape application table 32 can be level with the gripping end of the fixed gripper cylinder 36, so as to facilitate the subsequent pulling of the traction belt. After being pulled, in order to ensure that the tape can cover the splice of the traction belt, the second lifting cylinder 331 and the lower surface adhesive table 32 move in opposite directions, so that the tape can cover the upper surface of the splice of the traction belt.

[0039] As a further step, in combination Figure 1 , Figure 4 , Figure 5 and Figure 10As shown, the lower surface tape application unit 34 is located between the upper surface tape application unit 33 and the punching module 4. The lower surface tape application unit 34 also includes a third lifting cylinder 341, a second lifting plate 342, a second retracting cylinder 343, and an optical fiber sensor 344. The third lifting cylinder 341 is fixedly installed on the frame 1. The second lifting plate 342 is fixedly installed on the output end of the third lifting cylinder 341 and can move up and down under the drive of the third lifting cylinder 341. The second retracting cylinder 343 is fixedly installed on the surface of the second lifting plate 342 and is used to drive the moving gripper cylinder 37 of the lower surface tape application unit 34 to slide. The movement direction of the moving gripper cylinder 37 is perpendicular to the conveying direction of the conveying traction belt on the upper surface tape application table 31. The optical fiber sensor 344 is fixedly installed on the frame 1 and is a through-beam optical fiber sensor 344. Its optical path passes through the monitoring hole 411 on the punching table 41.

[0040] It is worth noting that the movable gripper cylinder 37 in the lower surface tape-applying unit 34 is slidably mounted on the second lifting plate 342. The tape guide unit 35, the fixed gripper cylinder 36, and the cutting unit 38 in the lower surface tape-applying unit 34 are all fixedly mounted on the second lifting plate 342, and the cutting blade of the cutting unit 38 is located between the fixed gripper cylinder 36 and the movable gripper cylinder 37, and can move vertically. Specifically, before pulling the tape, it is necessary to ensure that the tape surface is lower than the splice of the traction belt. Therefore, by driving the second lifting plate 342 through the third lifting cylinder 341, the tape end held by the fixed gripper cylinder 36 can be lower than the splice of the traction belt. During this period, since the movable gripper cylinder 37 and the fixed gripper cylinder 36 are both mounted on the second lifting plate 342, the movable gripper cylinder 37 can descend synchronously with the gripping end of the fixed gripper cylinder 36 and remain level, so as to facilitate the subsequent pulling of the traction belt. After being pulled, in order to ensure that the tape can cover the splice of the traction belt, the reverse movement of the third lifting cylinder 341 can make the tape cover the lower surface of the splice of the traction belt. Combined with the retraction of the first lifting cylinder 6, it can be ensured that the tape is attached to the lower surface of the splice of the traction belt.

[0041] It should be noted that the traction belt targeted in this invention has a film roll-like structure with multiple equidistant holes on both sides of its surface. In this invention, the fiber optic sensor 344 is electrically connected to the main controller. Through the through-beam type fiber optic sensor 344, the sensor can count the holes on the traction belt, preventing the traction belt from being over-transmitted or not yet delivered, ensuring that the traction belt docking point can be accurately moved to each section for operation.

[0042] As a further step, in combination Figure 2 , Figure 4 and Figure 6As shown, the pressure roller unit 39 of the upper surface tape application unit 33 and the lower surface tape application unit 34 have the same structure. Both include a Y-axis cylinder 391 fixedly mounted on the frame 1, a Z-axis cylinder 392 connected to the output end of the Y-axis cylinder 391, and a roller 393 rotatably mounted on the output end of the Z-axis cylinder 392. The roller 393, driven by the cooperation of the Y-axis cylinder 391 and the Z-axis cylinder 392, is used to smooth the tape and eliminate air bubbles. Specifically, the Z-axis cylinder 392 drives the roller 393 to contact the tape surface, and the Y-axis cylinder 391 drives the roller 393 to move on the tape surface, thereby achieving the smoothing and air bubble removal of the tape.

[0043] As a further step, in combination Figure 3 , Figure 6 , Figure 9 and Figure 11 As shown, the stamping unit 44 includes a punching part 441 for punching holes in the adhesive tape on the surface of the traction belt holes, a trimming part 442 for trimming excess adhesive tape on both sides of the traction belt, and a punching cylinder 443 for generating punching force; the punching table 41 is provided with a hole material channel 45 corresponding to the punching part 441 and an edge material channel 46 corresponding to the trimming part 442; a first waste box 9 is slidably disposed on the frame 1 below the hole material channel 45 and the edge material channel 46.

[0044] Specifically, after the punching part 441 punches holes in the tape at the splice of the traction belt, the punching waste can fall into the first waste box 9 through the hole material channel 45 for collection; after the trimming part 442 trims the excess tape on both sides of the splice of the traction belt, the trimming waste can fall into the first waste box 9 through the edge material channel 46 for collection; after the waste in the first waste box 9 is full, it can be cleaned by manually replacing the first waste box 9.

[0045] As a further step, in combination Figure 1 As shown, the waste hopper module 5 corresponding to the tail cutting unit 22 and the waste hopper module 5 corresponding to the head cutting unit 23 have the same structure. They both include a hopper cylinder 51 fixedly installed on the frame 1 and a receiving platform 52 fixedly connected to the output end of the hopper cylinder 51. The receiving platform 52 is slidably set on the table surface on the frame 1. The receiving platform 52 has a concave area, and a second waste box 53 is provided in the concave area.

[0046] When the traction belt is conveyed to the cutting table 21, the receiving platform 52 can stably support the traction belt, which can effectively prevent the traction belt from sagging and deforming due to its own weight, thereby ensuring the cutting accuracy of the tail cutting unit 22 and the head cutting unit 23, laying the foundation for subsequent high-precision splicing.

[0047] As a further step, in combination Figure 1As shown, an antistatic module 8 consisting of ion nozzles is fixedly installed on the stand 1. The antistatic module 8 is used to eliminate static electricity generated during the operation of the device, thereby improving the splicing accuracy of the traction belt.

[0048] As a further step, in combination Figure 1 , Figure 3 , Figure 9 , Figure 11 and Figure 12 As shown, the positioning module 7 includes a positioning cylinder 71 and a positioning pin 72. The positioning cylinder 71 drives the positioning pin 72 to pass through the holes on the traction belt to achieve positioning of the traction belt. Positioning channels 10 are respectively provided on the cutting table 21, the upper surface adhesive application table 31, the lower surface adhesive application table 32, the punching table 41, and the pressure plate 42. It is worth noting that the structural design of the positioning channel 10 in this invention can effectively prevent the positioning pin 72 from being forced to retract when the components are pressed and fixed, thus avoiding misalignment or displacement of the traction belt, thereby effectively ensuring the accuracy of the traction belt during cutting, splicing, or punching.

[0049] It is worth noting that in this invention, the lower surface adhesive application platform 32 is U-shaped. The gripping end of the moving claw cylinder 37 in the upper surface adhesive tape application unit 33 moves within the U-shaped groove of the lower surface adhesive application platform 32. Furthermore, the positioning channels 10 on the lower surface adhesive application platform 32 are opened from the two inner walls of the U-shaped groove and are equidistantly spaced from the surface of the lower surface adhesive application platform 32. Combined with... Figure 9 As shown, a mounting base can be provided on the output end of the positioning cylinder 71, and the positioning pin 72 is fixedly mounted on the mounting base. In this invention, when the positioning module 7 is used at the traction belt splicing and punching module 4 station, the positioning module 7 can be arranged on both sides of the splice seam of the two traction belt sections (i.e., the positioning pin 72 is located on both sides of the splice seam of the two traction belt sections), so that the splice is initially positioned and constrained by the positioning pin 72, thus stabilizing the position, effectively improving the splicing and punching accuracy, and ensuring the production quality of the traction belt splicing. Example 2

[0050] This invention also provides a method for automatic splicing of traction tapes in a flip-chip thin-film encapsulation process, comprising the following steps: S1. The operator places the tape roll on the tape guide unit 35 and pulls one end of the tape to the clamping end of the fixed gripper cylinder 36 for clamping and fixing. The end of the tape after clamping protrudes slightly from the clamping end of the fixed gripper cylinder 36. Specifically, tape rolls are placed on the tape guide unit 35 in the upper surface tape application unit 33 and the lower surface tape application unit 34, respectively.

[0051] S2. After the receiving platform 52 corresponding to the head cutting unit 23 moves to the conveying path under the drive of the hopper cylinder 51, a front traction belt is conveyed by the conveying mechanism, and the conveying stops when the tail end of the traction belt is about to enter the table surface of the cutting table 21. Then, the positioning cylinder 71 pushes the positioning pin 72 to enter the hole on the traction belt to achieve the initial positioning of the front traction belt, ensuring that the tail end of the traction belt is left 0.05mm outside the cutting table 21.

[0052] S3. The stabilizing cylinder 27 in the tail cutting unit 22 pushes the positioning plate 28 to press and position the front traction belt, ensuring the stability of the front traction belt's pressing and positioning and guaranteeing cutting accuracy. Then, the cutting cylinder 24 in the tail cutting unit 22 pushes the cutting blade 26 to cut the tail end of the front traction belt, removing an additional 0.05mm from the tail end. The waste material from the tail cutting can fall into the second waste box 53 corresponding to the tail cutting unit 22 under its own weight. It should be noted that when the cutting cylinder 24 pushes the cutting blade 26 down, the stabilizing cylinder 27 can simultaneously retract to ensure that the cutting blade 26 cuts the stable front traction belt.

[0053] S4. After the front traction belt is cut, each module is reset and the material conveying mechanism is started to convey the front traction belt. At the same time, the receiving platform 52 corresponding to the tail cutting unit 22 is moved to the material conveying path by the operation of the hopper cylinder 51, and then a rear traction belt is conveyed by the material conveying mechanism. The conveying stops when the head end of the traction belt slightly exceeds the table surface of the cutting table 21. Then, the positioning cylinder 71 pushes the positioning pin 72 to enter the hole on the traction belt to achieve the initial positioning of the rear traction belt and ensure that the head end of the traction belt extends precisely 0.05mm outside the cutting table 21.

[0054] S5. The stabilizing cylinder 27 in the head cutting unit 23 pushes the positioning plate 28 to press and position the rear traction belt, ensuring the stability of the pressing and positioning of the rear traction belt and guaranteeing the cutting accuracy. Then, the cutting cylinder 24 in the head cutting unit 23 pushes the cutting blade 26 to cut the head end of the rear traction belt, so that an additional 0.05mm is removed from the head of the traction belt. The waste material from the head cutting can fall into the second waste box 53 corresponding to the head cutting unit 23 under its own weight. It should be emphasized that when the cutting cylinder 24 pushes the cutting blade 26 down, the stabilizing cylinder 27 can retract simultaneously to ensure that the cutting blade 26 cuts the stable rear traction belt.

[0055] By cutting an additional 0.05mm from the tail of the front traction belt and the head of the rear traction belt, the two traction belts will not overlap during subsequent splicing, ensuring the accuracy of splicing. Furthermore, the cutting distance for the tail of the front traction belt and the head of the rear traction belt is not limited to 0.05mm, and the parameters can be adjusted appropriately according to the actual working conditions.

[0056] S6. After the rear traction belt is cut, each module is reset, and the feeding mechanism is started to transport the rear traction belt, so that the head of the rear traction belt and the tail of the front traction belt are joined at the adhesive tape unit 33 on the upper surface. After the joining is completed, the positioning cylinder 71 pushes the positioning pin 72 into the hole on the traction belt to achieve stable joining of the two traction belts. It should be noted that the traction belt targeted by this invention has holes on both sides (type of film roll structure); when the front traction belt is transported, the optical fiber sensor 344 can count the holes on the traction belt to prevent the position from being missed or not yet reached; and the optical fiber sensor 344 is connected to the controller, which is used to control each module according to the monitoring data of the optical fiber sensor 344.

[0057] S7. The first retracting cylinder 333 drives the moving gripper cylinder 37 in the upper surface tape applicator unit 33 to pull the tape located at the clamping end of the fixed gripper cylinder 36, so that the tape segment is placed above the joint of the two traction belts; and the second lifting cylinder 331 and the first lifting cylinder 6 simultaneously retract, so that while the lower surface tape applicator 32 presses and positions the two traction belts, the tape segment between the fixed gripper cylinder 36 and the moving gripper cylinder 37 can be attached to the upper surface of the joint of the two traction belts.

[0058] S8. Driven by the combined action of the Y-axis cylinder 391 and Z-axis cylinder 392 in the upper surface tape application unit 33, the roller 393 smooths and removes air bubbles from the tape on the upper surface of the joint between the two traction belt sections. Then, the tape is cut by the cutting unit 38 in the upper surface tape application unit 33, thus fixing the upper surface of the joint between the two traction belt sections. It should be noted that a gap channel is initially reserved between the lower surface tape application table 32 and the upper surface tape application table 31; the clamping end of the fixed gripper cylinder 36 and the clamping end of the movable gripper cylinder 37 are at the same level in the initial state; the cutting blade of the cutting unit 38 is located above the tape end in the initial state; furthermore, the Z-axis cylinder 392 drives the roller 393 to contact the tape surface, and the Y-axis cylinder 391 drives the roller 393 to move on the tape surface, achieving the smoothing and air bubble removal of the tape.

[0059] S9. After the upper surfaces of the two traction belt joints are fixed, each module is reset. The conveying mechanism is started to transport the traction belts, so that the joints of the two traction belts move to the lower surface tape application unit 34 with the assistance of the fiber optic sensor 344. At the same time, the positioning pin 72 is pushed into the hole on the traction belt by the positioning cylinder 71 at the bottom of the upper surface tape application table 31 and the punching table 41, so as to achieve precise movement and positioning of the joints of the two traction belts. This ensures that after the tape is applied, the lower surface tape can be completely aligned and adhered to the upper surface tape, effectively preventing misalignment. It should be noted that when the two traction belts are transported by the conveying mechanism, the fiber optic sensor 344 can count the holes on the traction belts to ensure that the joints can be accurately moved to the lower surface tape application unit 34.

[0060] S10. The second pull cylinder 343 drives the movable gripper cylinder 37 in the lower surface tape-applying unit 34 to pull the tape located at the clamping end of the fixed gripper cylinder 36, so that the tape segment is placed below the joint of the two traction belts; and the third lifting cylinder 341 pushes and the first lifting cylinder 6 retracts, so that the tape segment between the fixed gripper cylinder 36 and the movable gripper cylinder 37 can be attached to the lower surface of the joint of the two traction belts.

[0061] S11. Driven by the combined action of the Y-axis cylinder 391 and Z-axis cylinder 392 in the lower surface tape application unit 34, the roller 393 smooths and removes air bubbles from the tape on the lower surface of the joint between the two traction belt sections. Then, the tape is cut by the cutting unit 38 in the lower surface tape application unit 34, thus fixing the lower surface of the joint between the two traction belt sections. It should be noted that a gap channel is reserved between the lower surface tape application table 32 and the upper surface tape application table 31 in the initial state; the clamping end of the fixed gripper cylinder 36 and the clamping end of the movable gripper cylinder 37 are at the same level in the initial state; the cutting blade of the cutting unit 38 is located above the tape end in the initial state; furthermore, the Z-axis cylinder 392 drives the roller 393 to contact the tape surface, and the Y-axis cylinder 391 drives the roller 393 to move on the tape surface, achieving the smoothing and air bubble removal of the tape.

[0062] S12. After the lower surfaces of the joints between the two traction belt sections are fixed, each module is reset. The material conveying mechanism is started to transport the traction belts, so that the joints between the two traction belt sections are moved to the punching table 41 with the assistance of the fiber optic sensor 344. At the same time, the positioning cylinder 71 at the bottom of the punching table 41 pushes the positioning pin 72 into the hole on the traction belt, achieving precise positioning of the joints between the two traction belt sections. This ensures that the joints between the two traction belt sections are located at the hole material channel 45 and the edge material channel 46, which is beneficial for subsequent punching of the tape on the traction belt. It should be noted that when the two traction belt sections are transported by the conveying mechanism, the fiber optic sensor 344 can count the holes on the traction belt to ensure that the joints can be accurately moved to the punching table 41.

[0063] S13. The pre-fixing cylinder 43 pushes the stamping unit 44, so that the pressure plate 42 at the bottom of the stamping unit 44 can press and fix the two sections of traction belt, ensuring the stability of the traction belt during punching. Then, driven by the punching cylinder 443, the punching part 441 punches holes in the tape surface at the joint, and simultaneously the edge cutting part 442 cuts the tape on both sides at the joint. Finally, the punched traction belt is conveyed by the conveying mechanism to complete the splicing of the traction belt. It should be noted that during punching, the tape waste punched at the holes on the surface of the traction belt can fall into the first waste box 9 through the hole material channel 45, and the excess tape waste on both sides of the joint of the traction belt can fall into the first waste box 9 through the edge material channel 46. It should also be noted that during the entire splicing process of the traction belt, the static electricity generated during the operation of the device can be eliminated by the static electricity elimination module 8, thereby improving the splicing accuracy of the traction belt.

[0064] In summary, this invention, through the cooperation of the cutting module 2, the surface adhesive module 3, and the punching module 4, can collaboratively complete the cutting, double-sided bonding and splicing, and waste material punching of the traction tape. Furthermore, the positioning module 7, through its positioning constraint, fundamentally avoids positioning errors caused by manual splicing, effectively improving the splicing accuracy of the traction tape and ensuring the stability of subsequent flip-chip film encapsulation processes. Simultaneously, the automated operation method proposed by this device not only ensures that the splicing and cutting processes can be carried out without stopping the machine, but also eliminates traction tape contamination and physical damage caused by manual contact, effectively improving the splicing quality and production efficiency of the traction tape, significantly saving labor and time costs, and better matching the high-speed continuous production requirements of modern flip-chip film encapsulation production lines.

[0065] Furthermore, by dividing the cutting work between the tail cutting unit 22 and the head cutting unit 23, the present invention can cut off a certain length of the tail of the first traction belt and the head of the second traction belt respectively, so that the two traction belts will not overlap during subsequent splicing, thus ensuring the accuracy of splicing alignment.
