Description

Technical Field

[0001] This application relates to the field of circuit fabrication technology, specifically to a chip mounting apparatus and method for integrated circuit fabrication. Background Technology

[0002] Surface mount integrated circuits (SMD ICs) are used to achieve high-density electrical connections and functional integration on the PCB surface. Their operation relies on three steps: solder paste printing, placement positioning, and reflow soldering to complete the electrical and mechanical connections. Surface tension during reflow enables component self-alignment. Solder paste is printed on the pads, controlling its volume and position to lay the foundation for subsequent wetting. The pick-and-place machine uses vision and nozzles to place components on the solder paste, requiring high-precision alignment. As the temperature rises, the solder paste melts, and the surface tension and wetting force of the liquid solder pull the components towards the center of the pads (self-alignment). After cooling, a reliable solder joint is formed. Uneven wetting at both ends may lead to tombstoning.

[0003] Publication No. CN115623771B discloses a pick-and-place machine and its head. The head of the pick-and-place machine includes a frame, at least two linear motors, at least two lifting components, and at least two rotary drivers. The linear motors are connected to the frame, and each lifting component is correspondingly and floatingly connected to the output end of a linear motor. The linear motors drive the lifting components to move. The end of the lifting component away from the linear motor is used to pick up surface mount components. Each rotary driver is linked to a lifting component to drive the lifting component to rotate, thereby aligning the surface mount components with the circuit board. In this pick-and-place machine, the linear motors not only improve the accuracy of surface mount component movement but also eliminate the need for intermediate transmission mechanisms, improving the machine's structural compactness. The floating connection of the lifting components to the output ends of the linear motors provides floating space at the connection point, preventing the lifting components from getting stuck or tilted during lifting, which would reduce the accuracy of picking up and placing surface mount components.

[0004] Among them, the chip mounting feeding is mostly belt feeding. Belt feeding is to correctly load materials such as tape / tray / tube into the feeder and complete the position mapping and verification in the MES / pick-and-place machine program. The key is material verification, feeder type matching, tension and synchronization hole alignment, and functional self-test after the machine is started.

[0005] When feeding materials onto a belt conveyor, the reel needs to be removed, the belt pulled out, and the portion at the end that does not contain surface mount components cut off. The head of the new belt should also be cut off, and the two reels should be joined end to end with adhesive tape. Then, the belt should be wound up, and the new reel should be installed into the feeding system.

[0006] As for material splicing, incorrect splicing can directly lead to the pick-and-place machine accidentally sucking up / jumping, stopping, and rework. The most common root causes are tape feeding problems and poor tape splicing. Cutting size and misalignment of the splicing angle can also lead to poor splicing. Summary of the Invention

[0007] In view of this, the embodiments of this application aim to provide a chip mounting apparatus and method for integrated circuit processing, which can achieve automated and precise material receiving and improve the accuracy of material strip joints.

When the swing frame is in the first position, the slide is pulled by the tension spring to push out the first inclined surface and insert the second inclined surface between the second roller and the swing frame, so that the second roller is pushed outward and squeezes the elastic member. When the swing frame is in the second position, the slide is pulled by the tension spring to retract the first inclined surface and the second inclined surface, so that the elastic element supports the second roller to slide inward to the swing frame.

[0013] In some embodiments, the first mounting shaft and the second mounting shaft are both mounted inside the chuck. The inside of the chuck is provided with at least two positioning posts, and the positioning posts can be inserted into the first material strip or the second material strip. A first card seat and a second card seat are provided on both sides of the positioning posts. The inside of the first card seat and the second card seat is provided with a telescopic boss. There is at least an electromagnetic component between the boss and the card seat, and the electromagnetic component changes the telescopic length of the boss. A cutter is provided on one side of the boss so that when the boss extends to support the first and second material strips, the cutter cuts the first and second material strips.

[0014] In some embodiments, an electromagnetic plate is provided at both the engagement position and the disengagement position. The engagement device includes a locking plate, a plug rod, a ball head, and a magnetic post. The plug rod is inserted into the locking plate and can slide relative to the locking plate.

The connecting rod is connected to the upper roller or the lower roller. The passive magnet is installed on the outside of the connecting rod, and the active magnet is installed on the inside of the chuck, so that when the active magnet and the passive magnet cooperate to push the connecting rod to swing toward the first material strip and the second material strip, the adhesive part adheres to the surface of the first material strip or the second material strip.

[0016] In some embodiments, the cutter is retractable, a bridge is provided on the inner side of the cutter, the cutter is snapped into the inner side of the bridge, and a second magnetic control is provided on the side of the bridge away from the cutter.

The control clamp completes the connection between the first and second material strips at the clamping position to form a continuous material strip supply; when it is necessary to replace the material tray or perform maintenance, it switches to the disengagement position to release the connection; The vision system guides the nozzle to pick up components from the continuous tape and place them precisely on the PCB; when a feed station is completed or an abnormality occurs, it is switched to other feed units as needed to ensure the continuity and cycle time of the placement.

[0018] By setting up a clamp at each feeding position that can cycle between the fitting and disengaging positions, the first and second tapes can be automatically connected end to end, thereby ensuring a continuous and seamless tape supply, significantly reducing reel change downtime and manual intervention, and improving the continuity, capacity and yield of the mounting production line.

[0027] When feeding materials onto a belt conveyor, the reel needs to be removed, the belt pulled out, and the portion at the end that does not contain surface mount components cut off. The head of the new belt should also be cut off, and the two reels should be joined end to end with adhesive tape. Then, the belt should be wound up, and the new reel should be installed into the feeding system.

[0028] As for material splicing, incorrect splicing can directly lead to the pick-and-place machine accidentally sucking up / jumping, stopping, and rework. The most common root causes are tape feeding problems and poor tape splicing. Cutting size and misalignment of the splicing angle can also lead to poor splicing.

[0029] See Figure 1-18 As shown in the illustration, this application provides a chip mounting apparatus for integrated circuit processing, including a machine base 100, a mounting section 200, a vision system 300, and a feeding unit 400. The machine base 100 has a conveying guide rail arranged along a first direction for carrying and moving a PCB or a carrier platform. The mounting section 200 includes at least one nozzle capable of gripping components. The nozzle consists of a vacuum generator and an end-feed head. Guided by the vision system 300, the nozzle completes component pickup, angle and offset correction, and precise placement. The vision system 300 identifies component type, tape direction, tray position, and mounting coordinates on the PCB, and provides real-time correction data to the motion controller to correct the nozzle's gripping angle and placement offset.

[0030] The patch assembly includes at least two feeding units 400 arranged along the machine base 100. Each feeding unit 400 has multiple feeding positions for parallel or alternating feeding. Each feeding position is equipped with a first mounting shaft 10 and a second mounting shaft 20 for clamping different types or sizes of trays. Both the first mounting shaft 10 and the second mounting shaft 20 are mounted inside the chuck 21 to enable quick installation and removal of the trays. The first mounting shaft 10 is used to install the first tray, and the second mounting shaft 20 is used to install the second tray. After the first tray is fed, the second strip in the second tray aligns with the first strip in the first tray. Then, the first and second trays are removed, and the second tray is installed at the first mounting shaft 10 for cyclic feeding.

[0031] In some embodiments, each feeding position is provided with a clamp 30, which can cyclically move between a clamping position and a disengaging position: in the clamping position, the clamp 30 connects the first material strip head in the first material tray with the second material strip tail in the second material tray to form a continuous material strip supply; in the disengaging position, the clamp 30 disengages to replace the material tray or perform maintenance. An electromagnetic plate 61 is provided at the clamping position and the disengaging position, and the electromagnetic plate 61 cooperates with the clamp 30.

[0032] The clamping device 30 includes a clamping plate 62, a insertion rod 63, a ball head 64, and a magnetic post 65. The insertion rod 63 can slide relative to the clamping plate 62. The ball head 64 is located on the side of the insertion rod 63 facing the material strip to achieve flexible docking, and the structure of the ball head 64 can be pressed into the opening of the material strip. The magnetic post 65 is embedded on the back side of the insertion rod 63 and cooperates with the electromagnetic plate 61 in the mating and disengaging positions to achieve position locking or release. A conveyor belt 66 is provided inside the chuck 21 and is driven by a drive unit 67. The insertion rod 63 inserts into the conveyor belt 66 to smoothly transport the joint into the mounting path after docking is completed.

[0033] The combination of the interlocking device 30 with the conveyor belt 66 and the drive unit 67 enables continuous conveying after automatic connection, reduces sudden tension changes at the connection point, and ensures stable material supply.

[0034] In some embodiments, the feeding position includes a chuck 21, a reel, a swing frame 24, and a tension spring 25 working together to adapt the material strip to the winding. The chuck 21 is hinged to the machine base 100 and can swing relative to the machine base 100. A first reel 22 is embedded inside the chuck 21 for winding and unwinding the first material strip. The swing frame 24 is hinged to the chuck 21 and a second reel 23 is embedded inside the swing frame 24 for winding and unwinding the second material strip.

[0035] A tension spring 25 is provided between the swing frame 24 and the chuck 21. The tension spring 25 is stretched to provide pretension when the swing frame 24 switches between the first position and the second position. The chuck 21 has a first discharge port 26 facing the inside of the machine base 100 and a second discharge port 27 facing the swing frame 24. A drive unit is provided inside the machine base 100. The drive unit is located at the lower part of the chuck 21 and is used to pull the material belt portion that passes through the first discharge port 26 and the second discharge port 27, thereby realizing the simultaneous traction of material belts with different paths and recycling the film covering the surface of the material belt.

[0036] In some embodiments, the inner sides of the first reel 22 and the second reel 23 are provided with grooves 33, and the material strip is partially embedded in the grooves 33 to prevent slippage. The inner side of the swing frame 24 is provided with a slide 31 and connected to the swing frame 24 by a pin. The slide 31 can swing relative to the swing frame 24. The second reel 23 can slide and rotate relative to the swing frame 24. An elastic element 32 is provided between the second reel 23 and the swing frame 24 to provide support and cushioning. The elastic element 32 is a spring that supports the second reel 23 to retract into the swing frame 24.

[0037] The slide 31 is provided with a first inclined surface 34 and a second inclined surface 35. The first inclined surface 34 is housed inside the swing frame 24, and the second inclined surface 35 is located between the second reel 23 and the swing frame 24. Part of the slide 31 extends to the outside of the swing frame 24 and is connected to the tension spring 25. When the swing frame 24 is in the first position, the tension spring 25 pulls the slide 31 to push out the first inclined surface 34 and insert the second inclined surface 35 between the second reel 23 and the swing frame 24, thereby pushing the second reel 23 outward and squeezing the spring to change the position of the reel. After the position of the second reel 23 is changed, the second reel 23 and the second reel 24 are misaligned, so that after the swing frame 24 is lifted, the film recycling position will not interfere with the disassembly and assembly of the material tray, so as to facilitate operation and replacement. When the swing frame 24 is in the second position, the slide 31 retracts to restore the support of the elastic element 32, and the second roller 23 slides inward to the swing frame 24.

[0038] The combination of chuck 21, reel, swing frame 24, slide 31 and elastic element 32 can achieve adaptive installation of material trays of different diameters, maintain stable belt tension when material trays are replaced or connected, reduce material feeding vibration and improve traction reliability.

[0039] In some embodiments, the inner side of the chuck 21 is further provided with at least two positioning posts 41 for inserting the material strip and positioning the direction of the material strip. A first card seat 42 and a second card seat 43 are respectively provided on both sides of the positioning posts 41. The inner side of each card seat is provided with a retractable boss 44. An electromagnetic component 45 is arranged between the boss 44 and the card seat to change the retractable length of the boss 44.

[0040] A cutter 51 is provided on one side of the boss 44. When the boss 44 extends to support the material strip, the cutter 51 can cut the material strip to achieve segmentation or remove excess parts. The cutter 51 is a telescopic structure. A bridge 52 is provided on the inner side of the cutter 51. A second magnetic control 53 is provided on the side of the bridge 52 away from the cutter 51. The second magnetic control 53 includes a second active magnet 54 and a second passive magnet 55. The active magnet is fixed inside the chuck 21, and the passive magnet is fixed outside the bridge 52. The bridge 52 is driven by magnetic control to drive the cutter 51 to move.

[0041] The combination of positioning post 41, card holder, boss 44, cutter 51, bridge 52 and magnetic control can achieve precise positioning of the beginning and end of the material strip, provide stable support during connection or cutting and reduce cutting vibration and burrs, thereby ensuring connection quality and stable material feeding.

[0042] In some embodiments, to achieve reliable bonding of the beginning and end of the strip, an upper roller 71 and a lower roller 72 are provided on the inner side of the chuck 21 for mounting an adhesive component. The adhesive component is used to bond the beginning and end joints of the first and second strips. A first magnetic control 73 is disposed on one side of the upper roller 71 and the lower roller 72. The first magnetic control 73 includes a first active magnet 74, a first passive magnet 75, and a connecting rod 76. The connecting rod 76 is connected to the chuck 21 and can swing relative to the chuck 21. The connecting rod 76 is connected to the upper roller 71 or the lower roller 72. The first passive magnet 75 is installed on the outer side of the connecting rod 76, and the first active magnet 74 is installed on the inner side of the chuck 21. When the first active magnet 74 and the first passive magnet 75 cooperate to push the connecting rod 76 to swing toward the strip, the adhesive component adheres to the surface of the strip to complete the bonding.

[0043] The combination of upper roller 71, lower roller 72, adhesive component and magnetic control can realize automatic pressing of adhesive component, provide controllable pressure during the bonding process and reduce poor bonding, thereby improving the connection strength and reducing the risk of falling off.

[0044] The embodiments of this application are not limited to adhesives, as long as they can achieve the bonding between the strips. For example, in the embodiments of this application, the adhesive is a tape.

[0045] Electromagnetic plates 61 are provided at both the engagement and disengagement positions of the clamp 30 to cooperate with magnetic posts 65 for position control. The insert rod 63 of the clamp 30 inserts into the clamp plate 62 and can slide relative to the clamp plate 62. The ball head 64 is located on the side of the insert rod 63 facing the material strip and is integrally formed with the insert rod 63 to achieve flexible contact. The conveyor belt 66 inside the chuck 21 is driven by the drive unit 67 to smoothly transport the joint to the mounting path.

[0046] The combination of inserter 30, magnetic column 65, electromagnetic plate 61, conveyor belt 66 and drive unit 67 can realize automated head and tail connection, seamlessly send the connection point into the mounting track after connection and reduce tension changes and misalignment at the connection point.

[0047] In some embodiments, to ensure the surface flatness and bonding quality of the joint, the connecting rod 76 is oscillating under the control of the magnetic control during the pressing of the adhesive component to achieve controllable pressing force. The cooperation between the adhesive component and the upper roller 71 and the lower roller 72 can achieve uniform pressing under different material thicknesses and materials. The magnetic control cooperation between the cutter 51 and the bridge 52 realizes the flexible drive of the cutting action, avoiding mechanical impact damage to the material and chuck 21.

[0048] The combined effects of the various components of the entire feeding unit 400 include: automatic connection and disconnection of the tape head and tail, ensuring the bonding strength and surface flatness at the connection point, maintaining stable tape tension to ensure mounting cycle time, reducing manual intervention and improving production line continuity and yield.

[0049] This application also provides an integrated circuit chip mounting method, the steps of which are as follows: Insert the first and second material trays into each feeding position, install the shaft, and adjust the initial tension of the reel, tension spring 25, and elastic element 32.

[0050] Insert the head and tail of the strip into the positioning post 41 and align it with the guide hole. Confirm that the card holder and the boss 44 are in place to ensure stable positioning.

[0051] Drive the fitting 30 to the fitting position, and press the ball head 64 of the insertion rod 63 into the opening to achieve head-to-tail docking and lock the position.

[0052] The upper / lower rollers 72 press and bond the joint of the adhesive parts, and if necessary, the cutter 51 extends to remove excess material strip and reshape it.

[0053] The drive conveyor belt 66 starts slowly and sends the joint into the mounting path; the swing frame 24, the slide 31 and the spring work together to adjust the position of the roller to maintain stable tension.

[0054] Visual recognition of component and PCB coordinates, nozzle gripping and correcting angles and offsets, precise placement and secondary confirmation.

[0055] If jamming, connection failure, or abnormal tension is detected, the machine will revert to a pre-set strategy for retry or stop and alarm. After manual handling, the machine will be reset and resumed operation according to the procedure.
