Description

Technical Field

[0001] This utility model belongs to the field of panel manufacturing, and specifically relates to a soft thermal conductive sheet bonding system. Background Technology

[0002] In the semiconductor manufacturing industry, especially in panel manufacturing, flexible mounting tapes containing IC driver chips and microcircuits generate significant heat during operation. Therefore, a graphene-based thermal pad, commonly known as a heat sink, needs to be attached to the back of the IC chip. The bonding process between the flexible thermal pad and the flexible mounting tape, along with ensuring the correct bonding accuracy, is challenging. Current methods suffer from low bonding efficiency, large bonding accuracy deviations, crude inspection methods, and low yield rates. Traditional mounting processes have the following main drawbacks:

[0003] 1. Low efficiency in loading and unloading trays. Traditional placement processes currently only allow for manual loading of individual trays while the machine is stopped. After the placement process, the trays must be manually unloaded while the machine is stopped, and then moved to another machine for the next process. This repeated stopping and loading / unloading is cumbersome, inefficient, and shortens the equipment's lifespan.

[0004] 2. Low mounting efficiency. Traditional mounting processes can only achieve single-unit mounting, resulting in long mounting cycles, low efficiency, and severely insufficient production capacity. Furthermore, relying on relatively simple mechanical structures makes it difficult to maintain stable operation at high speeds and high precision, especially when handling different sizes, shapes, and materials. This can easily lead to size incompatibility, inaccurate or biased feeding, and numerous human factors, all of which affect mounting efficiency.

[0005] 3. Significant placement deviation. Traditional placement processes use a single sensor or low-resolution camera, resulting in low positioning accuracy and significant influence from factors such as ambient light and material properties, easily leading to placement position errors. This low-precision alignment technology cannot meet the demands of production lines when facing high-precision placement tasks.

[0006] 4. Crude inspection methods. Traditional mounting processes use a single low-resolution camera to only inspect the mounting position, film damage, bubbles, wrinkles, and other visual defects. They cannot detect micron-level problems such as cracks, scratches, contamination, foreign objects, or damage to microcircuits.

[0007] 5. Manually reorienting IC chips is complex. In traditional placement processes, after placement, reorienting the IC chip involves manually removing the tray and rewinding it in reverse. This is inefficient and can easily damage the IC chip surface and microcircuits. Utility Model Content

[0053] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention in any way.

[0054] Example 1

[0055] See attached document Figure 1 As shown, a flexible thermal conductive sheet coating system mainly includes an equipment cabinet 1 and a feeding unit I, a coating unit II, a detection unit III, and a receiving unit IV arranged in sequence according to the coating process inside the equipment cabinet 1. An intermediate buffer module 10 is provided between the coating unit II and the detection unit III.

[0056] like Figure 1 , 2As shown, the feeding unit I includes a main feeding tray 2 and an auxiliary feeding tray 3, both driven to rotate by two motors. The main feeding tray 2 and auxiliary feeding tray 3 are respectively used to mount flexible dressing tape rolls to enable feeding switching without stopping the machine. The flexible dressing tape on the flexible dressing tape roll is equipped with an IC driver chip and microcircuit, and has a protective film. A protective film guide wheel 23 and a flexible dressing tape guide wheel 29 are arranged between the main feeding tray 2 and the auxiliary feeding tray 3. After the flexible dressing tape 5 and the protective film 4 separate, the protective film 4 is fed out through the protective film guide wheel 23, and the flexible dressing tape 5 is fed out through the flexible dressing tape guide wheel 29. The feeding unit I is provided with a soft dressing tape feeding power ratchet 7 and a film guide groove 28 on the side facing the bonding unit II. The soft dressing tape feeding power ratchet 7 is used to send the separated soft dressing tape 5 to the bonding unit II in the next process. The film guide groove 28 is used to send the separated protective film 4 to the receiving unit IV so that it can be recombined with the soft dressing tape 5 after the bonding and testing processes are completed.

[0057] An electrostatic brush 22 is provided on one side of the guide film groove 28 to remove static electricity from the protective film 4. A tensioning wheel assembly and multiple protective film feeding guide wheels 21 are also provided between the protective film lead-out wheel 23 and the guide film groove 28. The tensioning wheel assembly, acting as a buffer mechanism, includes multiple guide wheels arranged in an alternating vertical arrangement. The separated protective film 4 is wound in a serpentine pattern within the tensioning wheel assembly, guided by the protective film feeding guide wheels 21 and destaticated by the electrostatic brush 22, before exiting through the guide film groove 28, entering above the laminating unit II, passing above the laminating unit II and the detection unit III, and entering the receiving unit IV. One guide wheel in the tensioning wheel assembly is mounted on the protective film vertical shift block 27, which can move up and down along a vertical track. The protective film vertical shift block 27 is also connected to a plumb bob II 36, the traction line of which is connected to a pulley on one side of the vertical track. In the buffer mechanism, three position sensors are set on the path of the vertical movement of the protective film vertical block 27: position sensor a24, position sensor b25, and position sensor c26. Position sensor a24 and position sensor c26 are used to limit the vertical movement of the protective film vertical block 27 to the two extreme positions, and position sensor b25 is the origin sensor to ensure that the protective film vertical block 27 can return to the starting origin after vertical movement.

[0058] Between the soft dressing tape lead-out wheel 29 and the soft dressing tape feeding power ratchet 7, a soft dressing tape feeding guide wheel 30 and a soft dressing tape feeding moving wheel 35 are also provided. The position of the soft dressing tape feeding guide wheel 30 is fixed. The soft dressing tape feeding moving wheel 35 is mounted on a soft dressing tape vertical moving block. The soft dressing tape vertical moving block is slidably set on a vertical track, and a plumb bob I 31 is connected to the soft dressing tape vertical moving block. The traction line of the plumb bob I 31 is wound around a pulley above the vertical track, thus forming a buffer mechanism. Three position sensors are set on the path of the soft dressing tape vertical moving block moving up and down, namely position sensor d32, position sensor e33 and position sensor f34. Position sensor d32 and position sensor f34 are used to limit the upper and lower extreme positions of the movement of the soft dressing tape feeding moving wheel 35, respectively. Position sensor e33 is an origin sensor to ensure that the soft dressing tape feeding moving wheel 35 can return to the starting origin after moving up and down. The separated soft dressing tape 5 passes by the soft dressing tape feeding guide wheel 30 and the soft dressing tape feeding moving wheel 35 in sequence, and is then fed to the adjacent applicator unit II by the soft dressing tape feeding power ratchet 7.

[0059] like Figure 1 , 3 As shown, the receiving unit IV includes a receiving module and a restoration module. The receiving module is used to collect the applied soft adhesive tape 5 and the protective film 4 separated from the feeding unit I, and combine the two together so that the protective film 4 is attached to the back of the IC chip on the soft adhesive tape 5. The restoration module is used to restore the orientation of the IC chip on the collected soft adhesive tape 5 to be the same as the IC orientation of the initial tray.

[0060] Specifically, such as Figure 3As shown, the receiving module includes a main receiving tray 18 and a secondary receiving tray 14, each driven to rotate by two motors; a protective film receiving wheel 37 disposed on one side of the main receiving tray 18; and a soft dressing tape receiving wheel assembly disposed on one side of the two receiving trays. The separated protective film bypasses the protective film receiving wheel 37 and is collected on the main receiving tray 18. The soft dressing tape receiving wheel assembly includes a soft dressing tape receiving power ratchet 85, a soft dressing tape receiving moving wheel 52, a first soft dressing tape receiving guide wheel 57, and a second soft dressing tape receiving guide wheel 58. The soft dressing tape receiving moving wheel 52 is mounted on a soft dressing tape vertical moving block, which is slidably disposed on a vertical track. A plumb bob V 54 is connected to the soft dressing tape vertical moving block, and the traction line of the plumb bob V 54 is wound around a pulley above the vertical track to form a buffer mechanism. Three position sensors are installed along the vertical movement path of the soft dressing strip vertical block: position sensor n51, position sensor p53, and position sensor q55. Position sensors n51 and q55 are used to limit the two extreme positions of the soft dressing strip receiving wheel 52. Position sensor p53 is an origin sensor to ensure that the soft dressing strip receiving wheel 52 returns to the starting origin after each movement. The soft dressing strip 5, after being covered and detected by the heat-conducting sheet, is collected by the main receiving tray 18 via the soft dressing strip receiving power ratchet 85, the soft dressing strip receiving wheel 52, the first soft dressing strip receiving guide wheel 57, and the second soft dressing strip receiving guide wheel 58.

[0061] The soft dressing tape 5 and the protective film 4 are combined on the main receiving tray 18, and the soft dressing tape product is transferred to the secondary receiving tray 14. The secondary receiving tray 14 and the restoration module work together to restore the soft dressing tape product so that the IC chip orientation on the soft dressing tape 5 is the same as the IC orientation on the initial tray.

[0062] The auxiliary receiving tray 14 is provided with multiple protective film guide rollers 50 on one side, which are used to deliver the soft dressing product to the restoration module.

[0063] Continue to refer to Figure 3As shown, the reduction module includes a reduction material tray 19 and protective film buffer assemblies and soft dressing tape buffer assemblies disposed on both sides of the reduction material tray 19. The reduction material tray 19 is driven to rotate by a motor. The protective film buffer assembly includes multiple protective film buffer guide wheels 39, which are arranged alternately vertically, so that the protective film 4 passes around the multiple protective film buffer guide wheels 39 in a serpentine pattern and enters the reduction material tray 19. Among them, the protective film buffer guide wheel 39 located in the middle is also disposed on the protective film guide wheel slider 43 that can move up and down, and three position sensors are disposed on one side of the movement path of the protective film guide wheel slider 43, namely position sensor g38, position sensor h40 and position sensor i41. Position sensor g38 and position sensor i41 are used to limit the two extreme positions of the vertical movement of the protective film guide wheel slider 43, and position sensor h40 is an origin sensor to ensure that the protective film guide wheel slider 43 returns to the starting origin after moving. The protective film guide wheel slider 43 is also connected to a plumb bob Ⅲ 42, and the traction line of the plumb bob Ⅲ 42 is wound around the corresponding pulley.

[0064] The soft dressing buffer assembly includes multiple soft dressing buffer guide wheels 49, one of which is a soft dressing buffer moving wheel 47 capable of moving up and down along a track. The soft dressing buffer moving wheel 47 is also connected to a plumb bob IV 48, the traction line of which is wound around a corresponding pulley. Similarly, three position sensors are installed on one side of the moving track of the soft dressing buffer moving wheel 47: position sensor j44, position sensor k45, and position sensor m46. Position sensor j44 and position sensor m46 respectively define the two extreme positions of the up and down movement of the soft dressing buffer moving wheel 47, while position sensor k45 is an origin sensor to ensure that the soft dressing buffer moving wheel 47 returns to its initial origin after movement.

[0065] The soft dressing tape on the secondary receiving tray 14 separates the soft dressing tape 5 and the protective film 4 again. The separated soft dressing tape 5 and the separated protective film 4 are collected by the return material tray 19 through the soft dressing tape buffer component and the protective film buffer component, respectively, to restore the orientation of the IC chip on the soft dressing tape 5.

[0066] The structure of the bonding unit II can be referred to Figure 1As shown, the system includes a track module 6, multiple vacuum suction modules 8, multiple support modules 9, and multiple rolling modules 11. The track module 6 is suspended in the air and includes two parallel, spaced-apart straight tracks. The front end of the track module 6 connects to a power ratchet 7 for feeding the soft dressing tape, and the rear end of the track module 6 is equipped with a conveyor wheel. The power ratchet 7 and the conveyor wheel work together to transport the separated soft dressing tape 5 along the track module 6. The support modules 9 are spaced along the length of the track module 6 on a platform below it, and are located directly below the track module 6. The support modules 9 are used to lift the soft dressing tape 5 above it through the spacing of the two straight tracks, so that the vacuum suction modules 8 can attach the adsorbed heat-conducting sheet to the soft dressing tape 5, and the rolling modules 11 can roll the attached heat-conducting sheet. The multiple vacuum suction modules 8 and the multiple rolling modules 11 are all spaced along the track module 6 and located on the same side outside the track module 6.

[0067] like Figure 4 As shown, the vacuum suction module 8 includes a feeding feeder 59, a suction X-axis moving module 60, a film platform 61, a protective baffle 62, a Z-axis moving module 63, a vision camera 64, a camera following module 65, a following camera 66, a rotary motor 67, a suction nozzle 68, a heat-conducting sheet 69, a detection camera 70, a waste box 71, and a module support 72. The module support 72 is fixed on the table surface, and the suction X-axis moving module 60 is fixed at the top of the module support 72, with its X-axis direction parallel to the conveying direction of the soft dressing belt 5. The Z-axis moving module 63 is slidably mounted on the suction X-axis moving module 60. A mounting plate is provided on the slider of the Z-axis moving module 63, and a rotary motor 67 is fixedly mounted on the mounting plate. The output shaft of the rotary motor 67 is connected to the suction nozzle 68, driving the suction nozzle 68 to rotate a certain angle in the plane, adjusting the direction of the heat-conducting sheet 69 sucked by the suction nozzle 68, so as to facilitate its application onto the soft dressing belt 5. A follower camera 66 and a camera follower module 65 mounting the follower camera 66 are also provided on one side of the module support 72. The movement of the follower camera 66 on the camera follower module 65 is synchronized with the movement of the rotary motor 67 on the suction X-axis moving module 60. The film platform 61 is used to transport the heat-conducting sheet 69 to be applied. The heat-conducting sheet 69 is fed to the film platform 61 by the sheet feeder 59. The vision camera 64 is suspended above the film platform 61 to determine whether there is a heat-conducting sheet 69. The sheet feeder 59 and the suction X-axis moving module 60 are separated by a protective baffle 62. A detection camera 70 and a waste box 71 are also provided below the film platform 61. The detection camera 70 takes pictures of the heat-conducting sheet 69 sucked by the suction nozzle 68 and performs PC position compensation.

[0068] like Figure 5As shown, the track module 6 is mounted on the track support 76. Multiple support modules 9 are positioned directly below the track module 6. The material receiving end of the track module 6 is connected to the soft dressing belt feeding power ratchet 7, and the material discharging end is connected to the soft dressing belt discharging power ratchet 56. The soft dressing belt feeding power ratchet 7 and the soft dressing belt discharging power ratchet 56 cooperate to form a power conveying module for transporting the soft dressing belt 5. Furthermore, a material receiving sensor 96 is also provided at the material receiving end of the track module 6 to detect whether the soft dressing belt 5 has entered the track module 6.

[0069] Preferably, the widths of the two linear tracks in the track module 6 are adjustable. One of the linear tracks is movably mounted on a slide rod and connected to a track module motor 73 on one side of the track module 6. The track module motor 73 drives the linear track to move along the slide rod, thereby adjusting the distance between the two linear tracks. Optionally, the track module motor 73 can drive the linear track using a ball screw mechanism. A track distance adjustment digital display 75 is also provided at the discharge end of the track module 6 to make the adjusted track distance visible, allowing operators to easily understand the values ​​of the current and next adjustment.

[0070] like Figure 6 As shown, the support module includes a vacuum platform, a lower limit sensor 77, an upper motor 78, a support moving motor 79, a vacuum platform bracket 80, an upper limit sensor 81, and a support X-axis moving module 82. The support X-axis moving module 82 is mounted on a platform below the track module. A slider on the support X-axis moving module 82 is connected to the support bracket. The support moving motor 79 drives the slider to move the support bracket along the X-axis, i.e., along the conveying direction of the soft dressing belt 5. The support bracket is equipped with an upper motor 78, which drives the vacuum platform bracket 80 to move vertically up and down. A vacuum platform is fixedly mounted on the top surface of the vacuum platform bracket 80. Depending on the location of the support module 9, the vacuum platform is divided into an adhesive vacuum platform 74 and a rolling vacuum platform 97. When the support module 9 is located at the vacuum suction module 8, the vacuum platform is the adhesive vacuum platform 74; when the support module 9 is located at the rolling module 11, the vacuum platform is the rolling vacuum platform 97. The vacuum platform is used to adsorb the soft dressing tape 5, ensuring a flat application surface and facilitating the application of the heat-conducting sheet 69 or its subsequent rolling. Furthermore, the support bracket is also equipped with a lower limit sensor 77 and an upper limit sensor 81 to detect the position of the vacuum platform bracket 80 and control the shutdown of the upper motor 78.

[0071] During the application of the heat-conducting sheet 69, the upper motor 78 lifts the application vacuum platform 74, causing it to raise the area on the soft dressing 5 where the sheet needs to be applied to a certain height, facilitating the application of the heat-conducting sheet 69. When rolling is required after application, the upper motor 78 lifts the rolling vacuum platform 97, causing it to raise the area on the soft dressing 5 where the heat-conducting sheet 69 is applied and where rolling is required to a certain height, facilitating the flattening of the heat-conducting sheet 69.

[0072] The structure of the rolling module 11 is as follows: Figure 11 As shown, the system includes a rolling cylinder 98, a rolling X-axis moving module 99, rollers 100, a rolling Y-axis moving module 101, a vertically adjustable micrometer mechanism 102, and a rolling module support 103. The rolling module support is fixed to one side of the track module. A vertically adjustable micrometer mechanism 102 is installed at the top of the rolling module support. The rolling X-axis moving module 99 is mounted on the movable end of the vertically adjustable micrometer mechanism 102. The rolling Y-axis moving module 101 is slidably connected to the rolling X-axis moving module 99. A mounting plate is slidably connected to the rolling Y-axis moving module 101. The rolling cylinder 98 is fixed on the mounting plate. A roller support is connected to the telescopic end of the rolling cylinder 98. A freely rolling roller 100 is provided on the roller support. When it is necessary to roll the soft pad 5 covering the heat-conducting sheet 69, the position of the roller 100 is adjusted by the vertically adjustable micrometer mechanism 102 and the rolling X-axis moving module 99, and then the rolling Y-axis moving module 101 drives the roller 100 to roll.

[0073] like Figure 7 As shown, the detection unit III includes a first camera module 13, a second camera module 15, a third camera module 20, an upper human inspection camera 16, a lower human inspection camera 87, and a detection track 84. The detection track 84 has the same structure as the track module, with a detection loading power ratchet 83 and a soft-coverage tape receiving power ratchet 85 respectively installed at its front and rear ends to transport the soft-coverage tape 5 to the receiving unit IV. The first camera module 13, the third camera module 20, and the lower human inspection camera 87 are located below the detection track 84, while the second camera module 15 and the upper human inspection camera 16 are located above the detection track 84. Specifically, the first camera module 13 is used to inspect IC surface chip defects on the soft-coverage tape, the second camera module 15 is used to inspect PI surface thermal conductive sheet defects on the soft-coverage tape, and the third camera module 20 is used to inspect SR surface soft-coverage tape defects. The upper human inspection camera 16 and the lower human inspection camera 87 perform human inspection re-judgment for specific problems.

[0074] Specifically, the structure of the first camera module 13 is as follows: Figure 8 As shown, it includes a coaxial light source 88 and an IC detection camera 89 connected to each other. The structure of the second camera module 15 is as follows. Figure 9As shown, the device includes a PI detection camera 90, a bar light source 91, and a camera module bracket 92. The camera module bracket 92 is fixed on the table surface, and the PI detection camera 90 and the bar light source 91 are mounted on the camera module bracket 92, with the PI detection camera 90 positioned above the bar light source 91.

[0075] The defective products that passed inspection require further processing. Therefore, the inspection track 84 of the inspection unit III is further equipped with a blade removal module 17, which is used to remove and cut off the substandard heat-conducting sheets 69. The structure of the blade removal module 17 is as follows: Figure 12 As shown, the assembly includes a punching cylinder 104, a punching die head 105, a lower die 106, a receiving box 107, a moving module motor 108, an upper lifting module 109, and a blade removal module support 110. A fixed platform is vertically supported at the center of the blade removal module support 110. The lower die 106 is mounted above the fixed platform. The upper surface of the lower die 106 has a channel groove for the passage of the flexible tape 5, and a punching opening is provided at the channel groove so that the removed heat-conducting sheet 69 and the corresponding flexible tape 5 fall into the receiving box 107 below through the punching opening. The receiving box 107 is connected to the moving module. The moving module motor 108 controls the horizontal linear movement of the receiving box 107 to remove waste material. The direction of movement is perpendicular to the conveying direction of the flexible tape 5. The bottom of the receiving box 107 is also connected to the upper lifting module 108, which lifts the receiving box 107 to catch the removed waste material. The punching cylinder 104 is installed at the top of the blade separation module bracket 110. The piston rod of the punching cylinder 104 is connected to the punching die head 105. The punching die head 105 is located directly above the punching opening. The punching cylinder 104 drives the punching die head 105 to move downward to cut off the unqualified heat-conducting sheet 69.

[0076] A burr detection module 86 is provided in front of the blade removal module 17. The burr detection module 86 uses a camera to take pictures of the cut soft dressing 5, and then inspects the burrs, scratches and other defects of the cut.

[0077] Preferred, such as Figure 1 As shown, an intermediate buffer module 10 is also provided between the application unit II and the detection unit III. The intermediate buffer module 10 is a pulley that can be raised and lowered vertically. The position of the pulley is lower than the track module 6 and the detection track 84, so that when the soft dressing tape 5 enters the detection unit III through the intermediate buffer module 10, it forms a V-shape to store a certain length in order to deal with various problems encountered on the subsequent production line, such as alarm shutdown, manual inspection, missed application, and re-application after moving back a few steps.

[0078] Preferably, a leak detection camera module 12 is also provided at the end of the track module 6. The soft dressing tape 5, after the heat-conducting sheet 69 has been applied and rolled, is sent to the leak detection camera module 12. The leak detection camera module 12 scans and photographs the soft dressing tape 5 and compares it with a preset standard image to check for problems such as missing application, application position deviation, uneven adhesion, etc. If a problem is found, a signal is transmitted to the control unit, the machine stops running and alarms, and the display screen shows a description of the problem and a photo. The structure of the leak detection camera module 12 is as follows: Figure 10 As shown, it includes a camera module bracket 92 and a pressure regulating valve 93, a missed detection camera 94, and a ring light source 95 arranged from top to bottom on the camera module bracket 92.

[0079] Example 2

[0080] The working process of the soft thermal conductive sheet coating system of this utility model will be described below with reference to the structure of Embodiment 1, so as to more clearly show the setting method and the idea of ​​solving the technical problem of this utility model.

[0081] The work process includes the following steps:

[0082] 1. The whole machine is powered on and in standby mode, and the feeding unit starts feeding.

[0083] like Figure 2 As shown, the main feeding tray 2 rotates under the drive of a motor. The material roll on the main feeding tray 2 is fed out as a soft dressing belt 5 via a soft dressing belt lead-out wheel 29 and a soft dressing belt feeding guide wheel 30, and then fed out as a protective film 4 via a protective film lead-out wheel 23, thereby separating the soft dressing belt 5 and the protective film 4 on the material roll and feeding them out separately. The feeding process of the soft dressing belt 5 and the protective film 4 is carried out simultaneously, as detailed below:

[0084] (1) During the subsequent feeding process of the soft dressing belt 5, the soft dressing belt vertical displacement block 35 moves to the lower limit trigger position sensor f34, the main feeding plate 2 stops rotating forward, the soft dressing belt feeding power ratchet 7 rotates forward to feed the soft dressing belt 5, the soft dressing belt vertical displacement block 35 moves to the upper limit trigger position sensor d32, the soft dressing belt feeding power ratchet 7 stops rotating forward, the main feeding plate 2 rotates forward to send out the soft dressing belt, and so on to complete the feeding action of the soft dressing belt 5;

[0085] (2) During the subsequent conveying of the protective film 4, the protective film vertical displacement block 27 moves to the lower limit trigger position sensor c26, the main feeding tray 2 stops rotating forward, and the protective film 4 is sent to the main receiving tray 18 via the protective film feeding guide wheel 21 and the guide groove 28. The main receiving tray 18 rotates forward to recycle the protective film 4, and the protective film vertical displacement block 27 moves to the upper limit trigger position sensor a24, and the main receiving tray 18 stops rotating forward. This cycle is repeated to complete the feeding and recycling action of the protective film 4. Similarly, the soft covering belt 5 and the protective film 4 on the auxiliary feeding tray operate in the same way.

[0086] 2. Preparations before applying the heat-conducting pad

[0087] like Figure 5 As shown, the soft dressing tape feeding power ratchet 7 and the soft dressing tape discharging power ratchet 56 rotate synchronously at a set speed. When the incoming material sensor 96 triggers the IC chip on the soft dressing tape 5, the soft dressing tape feeding power ratchet 7 and the soft dressing tape discharging power ratchet 56 simultaneously deliver four empty soft dressing tapes 5 to the bonding vacuum platform 74 to be bonded to the heat-conducting sheet 69. Meanwhile, as... Figure 1 , Figure 6 As shown, the upward motor 78 on the support module 9 rotates forward and pushes upward, triggering the upper limit sensor 81. The upward motor 78 stops and remains in position, while the vacuum platform 74 draws a vacuum, causing the soft dressing strip 5 to be raised and vacuum-applied. The raised shape is to prevent the adjacent IC chip on the soft dressing strip 5 from being squeezed when the suction nozzle 68 moves downward. Vacuum application is to ensure a flat and stable application surface. After the support module 9 completes the upward action, it waits for the heat-conducting sheet 69 to be applied.

[0088] 3. Application of heat-conducting pads

[0089] The support module 9 has been mounted and the soft dressing 5 has been vacuum-applied. The vision camera 64 positions the IC chip on the raised soft dressing 5. Figure 4 As shown, the X-axis moving module 60 drives the rotary motor 67 and the suction nozzle 68 to move simultaneously to the film platform 61. The suction nozzle 68 creates a vacuum and sucks up the heat-conducting sheet 69 from the film platform 61. The suction nozzle 68 rises, and the X-axis moving module 60 drives the rotary motor 67 and the suction nozzle 68 with the heat-conducting sheet 69 to the bonding vacuum platform 74. The detection camera 70 takes a picture of the heat-conducting sheet 69 and performs PC position compensation. The suction nozzle 68 descends to break the vacuum, completing the bonding process. Figure 1 , Figure 6 As shown, the vacuum platform 74 on the bearing module 9 breaks the vacuum, the upper motor 78 reverses and descends, triggering the lower limit sensor 77, and the upper motor 78 stops and remains in position. Figure 5 As shown, the soft dressing tape feeding ratchet 7 and the soft dressing tape discharging ratchet 56 simultaneously deliver the soft dressing tape 5, with the heat-conducting sheet 69 attached, to the rolling vacuum platform 97 at a set speed. As described above, in Figure 4 As shown, while the suction nozzle 68 rises, the film platform 61 retracts, and the feeder 59 delivers the next heat-conducting sheet to be suctioned by the nozzle 68. Figure 1 As shown, the four vacuum suction modules 8 perform suction application simultaneously.

[0090] 4. Rolling

[0091] The applied soft dressing 5 is conveyed to the roller vacuum platform 97, as follows: Figure 1 , Figure 6As shown, the upward motor 78 on the support module 9 rotates forward and pushes upward, triggering the upper limit sensor 81. The upward motor 78 stops and remains stationary, while the rolling vacuum platform 97 draws a vacuum. This causes the soft dressing strip 5 with the heat-conducting sheet 4 attached to it to be pushed up and vacuum-assisted. Figure 11 As shown, the protrusions are designed to prevent the roller 100 from pressing against adjacent IC chips on the soft adhesive strip 5 when it moves downwards. Vacuum adhesion ensures a flat and stable application surface. The support module 9 completes the rolling process. Figure 11 As shown, the rolling cylinder 98 descends, the roller 100 contacts the protruding part of the soft padding belt 5, and the rolling Y-axis moving module 101 is pushed forward, with the roller 100 completing the rolling process. Figure 1 , Figure 6 As shown, the rolling vacuum platform 97 on the bearing module 9 breaks the vacuum, the upper motor 78 reverses and descends, triggering the lower limit sensor 77, and the upper motor 78 stops and remains in position. Figure 5 , Figure 7 As shown, the soft dressing tape feeding power ratchet 7 and the soft dressing tape discharging power ratchet 56 simultaneously deliver the soft dressing tape 5 with the heat-conducting sheet 69 attached to it to the missed detection camera module 12 for inspection at a set speed.

[0092] 5. Inspect the application effect

[0093] exist Figure 1 , Figure 10 As shown, the defect detection camera 12 scans and photographs the production process. Through image processing and comparison with preset standard images, it checks for defects such as missing application of the rolled soft adhesive tape 5, deviations in application position, and uneven adhesion. If a problem is found, a signal is transmitted to the control unit, the machine stops running and an alarm sounds, and the display screen shows a description of the problem and a photograph. Figure 5 , Figure 7 As shown, the soft dressing belt feeding power ratchet 7 and the soft dressing belt discharging power ratchet 56 simultaneously deliver the qualified soft dressing belt 5 to the inspection feeding power ratchet 83 and the soft dressing belt receiving power ratchet 85 at a set speed.

[0094] 6. AOI Detection

[0095] The applied flexible tape 5 is transferred to the AOI inspection area of ​​inspection unit III via intermediate buffer module 10, inspection feeding power ratchet 83, and flexible tape receiving power ratchet 85. First camera module 13 inspects for IC surface chip defects, second camera module 15 inspects for PI surface thermal conductive sheet defects, and third camera module 20 inspects for SR surface flexible tape defects. Human inspection upper camera 16 and human inspection lower camera 87 perform human inspection re-judgment for special issues.

[0096] 7. Handling of problematic products

[0097] All defective products detected by the camera module are conveyed to the cutting position of the cutter module 17 by the detection feeding power ratchet 83 and the soft dressing tape receiving power ratchet 85. The display screen shows the problem description and photos, and the cutter module 17 cuts off the defective heat-conducting sheet 4. The cutter module 17 can be manually controlled by buttons to perform the cut. The size of the cut rectangle is the same as that of the heat-conducting sheet, and the center of the soft dressing tape 5 has a rectangular cut. After the cut, the power locking hole of the soft dressing tape 5 remains intact to ensure normal feeding by the detection feeding power ratchet 83 and the soft dressing tape receiving power ratchet 85. At the same time, the operator can perform a re-inspection. After the cut, the soft dressing tape 5 is inspected by the burr detection module 86 for burrs, scratches, etc.

[0098] Understandably, when there are no defective products, the soft dressing 5 simply passes through the knife separation module 17 and the burr detection module 86.

[0099] 8. Receiving qualified products

[0100] The loading ratchet 83 and the receiving ratchet 85, used for detecting material feeding, transport the cut-off soft dressing 5 to the receiving unit IV. The receiving unit IV... Figure 3 As shown, the soft dressing tape receiving power ratchet 85 delivers the applied and inspected soft dressing tape 5, while simultaneously retrieving the protective film 4 via the protective film receiving wheel 37. The receiving power for the protective film 4 is provided by the main receiving tray 18. The soft dressing tape 5 moves to the lower limit trigger position sensor n51 via the soft dressing tape receiving moving wheel 52, stopping the soft dressing tape discharge power ratchet 56 and causing the main receiving tray 18 motor to rotate forward and retract the soft dressing tape 5. The soft dressing tape receiving moving wheel 52 moves to the upper limit trigger position sensor q55, stopping the main receiving tray 18 motor and simultaneously causing the soft dressing tape receiving power ratchet 85 motor to rotate forward and retract the soft dressing tape 5. This cycle completes the soft dressing tape 5 receiving action. The soft dressing tape 5 passes through a buffer mechanism composed of the soft dressing tape receiving moving wheel 52, a plumb bob V54, and position sensors n51, p53, and q55. The buffer mechanism utilizes the principle that the weight of the plumb bob V54 matches that of the soft dressing tape receiving moving wheel 52. All buffer mechanisms or components in the device employ this principle to maintain the flexible tape 5 under tension and stability throughout the device. As described above, the main take-up tray 18 simultaneously retracts the protective film 4 and the flexible tape 5, with the protective film 4 attached to the back of the IC chip on the flexible tape 5.

[0101] 9. Soft compress bandage for recovery

[0102] exist Figure 3As shown, since the IC chip on the applied soft dressing tape is opposite to the IC orientation of the initial tray, it needs to be restored to its original orientation via the return tray 19. The protective film 4 and the soft dressing tape 5 on the secondary receiving tray 14 are retrieved through their respective buffer components. The soft dressing tape 5 is fed out by the reverse motor of the secondary receiving tray 14, and enters the return tray via the soft dressing tape buffer component. During this process, the soft dressing tape buffer moving wheel 47 moves to the lower limit trigger position sensor m46, the secondary receiving tray 14 motor stops reversing, and the return tray 19 motor starts reversing to retrieve the soft dressing tape 5; the soft dressing tape buffer moving wheel 47 moves to the upper limit trigger position sensor j44, and the return tray 19 motor stops reversing, thus completing the process of restoring the IC chip orientation of the soft dressing tape 5. In the same way, the protective film 4 is restored and retrieved to the return tray via the protective film guide wheel 50 and the protective film guide wheel slider 43 in the protective film buffer component.
