Abstract
Description
Technical Field
[0001] This utility model relates to the field of semiconductor manufacturing, and in particular to a tape and reel machine with a buffer component. Background Technology
[0002] Tape and reel machines are a crucial component in the wafer packaging process, used for heat-sealing and packaging wafers after sorting.
[0003] Most tape and reel machines on the market currently use a single ratchet as the traction device to drive the carrier tape and package the wafers. The traction device generates a large traction force on the carrier tape when it drives the carrier tape to peel off the reel, giving the carrier tape itself a large tension.
[0004] However, in the process of implementing the technical solutions in the embodiments of this application, the applicant discovered that the above-mentioned technology has at least the following technical problems:
[0005] When the end of the carrier tape breaks on the reel, the tension causes a large displacement of the portion of the carrier tape in the front taping track, which in turn causes a deviation in the position of the carrier tape and the wafer during the taping process. Utility Model Content
[0006] The purpose of this invention is to provide a tape and reel machine with a buffer component to solve the problem in the prior art where the tension of the traction device on the carrier tape causes additional displacement of the carrier tape when the roll breaks.
[0007] The technical solution of this utility model is: a tape feeding machine with a buffer component, comprising a base, wherein a carrier tape feeding mechanism, a tape feeding component, and a buffer component are disposed on the base.
[0008] The carrier tape feeding mechanism is used to output the carrier tape;
[0009] The tape feeding assembly includes a tape feeding ratchet and a tape feeding track. The tape feeding ratchet connects to the first section of the carrier tape and feeds the carrier tape into the tape feeding track.
[0010] The buffer assembly is disposed between the carrier tape feeding mechanism and the tape feeding assembly, and includes a buffer ratchet. The buffer ratchet is connected to the middle of the carrier tape and pulls the carrier tape out of the reel.
[0011] The carrier tape placed between the cache component and the tape-tapping component is in a relaxed state.
[0012] Preferably, the cache component includes a cache base plate fixed to the base, a cache driver is disposed on the cache base plate, and the cache ratchet is connected to the execution end of the cache driver;
[0013] The buffer base plate is fixed with a buffer track, and the buffer track has a drive groove on the rim of the buffer ratchet. The two sides of the carrier belt are mounted on the buffer track, and the middle part is suspended and driven by the rim of the buffer ratchet.
[0014] Preferably, one side of the buffer track is configured as an adjustable stop, which can move along the width direction of the buffer track to accommodate carrier tapes of different sizes.
[0015] Preferably, a clamping mechanism is provided corresponding to the buffer track. The clamping mechanism includes a carrier belt pressure roller, which is disposed on a pressure roller mounting seat. The pressure roller mounting seat cooperates with a pressure roller lifting rod in the vertical direction. An elastic element is sleeved on the pressure roller lifting rod, and the elastic element applies a spring force toward the buffer track to the pressure roller mounting seat.
[0016] Preferably, a steering wheel is provided at the front end of the buffer track, and the steering wheel is tangent to the plane on which the buffer track is located.
[0017] Preferably, a detection component is provided on the base, the detection component having a first detection end and a second detection end arranged along the length direction of the carrier tape.
[0018] Preferably, the detection assembly includes a detection mounting frame fixed to the base, and a first detector and a second detector are sequentially arranged on the detection mounting frame along the height direction.
[0019] Compared with the prior art, the advantages of this utility model are:
[0020] (1) In this application, the buffer ratchet in the buffer assembly shares the traction force of the taping ratchet, so that the taping ratchet only needs to maintain the driving force for carrier tape transport, while the main traction force required for peeling the carrier tape is borne by the buffer ratchet, thereby significantly reducing the tension of the carrier tape in the taping assembly section. The slack section of the carrier tape between the buffer assembly and the taping assembly can buffer the tension impact at the moment of tape breakage, avoid the severe displacement of the front end of the carrier tape due to sudden tension change, and ensure that the relative position of the carrier tape and the wafer remains stable.
[0021] (2) The adjustable edge design of the buffer track, combined with the elastic holding function of the clamping mechanism, can adapt to different widths of carrier belts. The carrier belt pressure rollers that make rolling contact provide uniform pressure while avoiding damage to the surface of the carrier belt. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to specific embodiments:
[0029] like Figure 1 As shown, a tape and reel machine with a buffer component includes a base 1, on which a carrier tape feeding mechanism, a tape and reel assembly 2 and a buffer component 3 are disposed.
[0030] The carrier tape feeding mechanism includes a spool on which a carrier tape is wound. The carrier tape has pre-drilled traction holes along its length, with multiple adjacent traction holes having the same spacing. The tape feeding assembly 2 includes a tape feeding ratchet 21 and a tape feeding track 22. The rim of the tape feeding ratchet 21 has teeth that can engage with the traction holes on the carrier tape, and thus drives the carrier tape into the tape feeding track 22 for tape feeding operations through its own rotation.
[0031] The carrier tapes, layered and wound on the reel, have adhesion between them. Therefore, in the prior art, the traction force exerted by the taping ratchet 21 on the carrier tape needs to reach a relatively large value to output the carrier tape, thus generating corresponding tension in the carrier tape. This tension is balanced by the tension of the reel on the carrier tape while the carrier tape still has a portion wrapped around it. However, when the carrier tape is nearing the end of its use, i.e., when the reel is broken, this tension can cause the carrier tape to suddenly shift, thereby affecting the relative positional relationship between the first section of the carrier tape and the wafer being taped, and consequently affecting the taping effect.
[0032] To solve this problem, such as Figure 2 and Figure 3As shown, this application provides a buffer assembly 3 between the carrier tape feeding mechanism and the tape feeding assembly 2. The buffer assembly 3 includes a buffer ratchet 31, which has the same or similar tooth structure as the tape feeding ratchet 21 and is connected to the middle of the carrier tape. This ratchet 31 replaces the tape feeding ratchet 21 in applying a traction force to the carrier tape that can peel it off the spool, thereby reducing the traction force of the tape feeding ratchet 21 on the carrier tape, and thus making the part of the carrier tape located between the buffer assembly 3 and the tape feeding assembly 2 in a relaxed state.
[0033] Specifically, the cache component 3 includes a cache base plate 32 fixed to the base 1. A cache driver 33 is fixed on one side of the cache base plate 32 via a driver mounting seat 38. The actuator end of the driver is connected to a cache ratchet 31 provided on the other side of the cache base plate 32 via a transmission mechanism 37 that passes through the cache base plate 32, and drives the cache ratchet 31 to rotate.
[0034] A buffer track 34 is vertically fixed on the buffer base plate 32. A drive groove 341 is formed on the rim of the buffer ratchet 31 corresponding to the buffer base plate 32. This arrangement allows both ends of the carrier belt to be mounted on the buffer track 34, with the middle of the belt suspended in the air, thus being driven by the rim of the buffer ratchet 31 that passes through the drive groove 341. Furthermore, to accommodate carrier belts of different sizes, one side of the buffer track 34 is configured as an adjustable flange 342. The adjustable flange 342 can be adjusted along the width direction of the buffer track 34, thereby changing the width of the buffer track 34.
[0035] To ensure the carrier belt adheres to the buffer track 34, a clamping mechanism 35 is provided corresponding to the buffer track 34. The clamping mechanism 35 includes a carrier belt pressure roller 351, the axis of which is parallel to the axis of the buffer ratchet 31. One side of the carrier belt pressure roller 351 is rotatably connected to a pressure roller mounting base 352. The pressure roller mounting base 352 is slidably engaged with a pressure roller lifting rod 353 arranged vertically. A limit block 354 is provided at the top of the pressure roller lifting rod 353, and an elastic element is sleeved on the pressure roller lifting rod 353. Both ends of the elastic element abut against the limit block 354 and the pressure roller mounting base 352, respectively, thereby applying a spring force towards the buffer track 34 to the pressure roller mounting base 352. This allows the carrier belt pressure roller 351 to roll and contact the carrier belt while simultaneously clamping the carrier belt onto the buffer track 34.
[0036] In addition, a steering wheel 36 is installed at the front end of the buffer track 34. The axis of the steering wheel is parallel to the axis of the buffer ratchet 31, and the steering wheel 36 is tangent to the plane of the buffer track 34, so that it is used to turn the carrier belt after it is output from the carrier belt feeding mechanism.
[0037] The base 1 is also equipped with a detection component 4, which, in conjunction with Figure 4As shown, the detection component 4 includes a detection mounting frame 41 fixed to the base 1. A first detector 42 and a second detector 43 are sequentially arranged on the detection mounting frame 41 along the height direction. The U-shaped area of the carrier tape that is relaxed between the buffer component 3 and the tape assembly 2 is placed in the detection interval of the first detector 42 and the second detector 43.
[0038] During work:
[0039] The carrier belt is manually pulled out from the carrier belt feeding mechanism and placed onto the buffer track 34 via the steering wheel 36. The clamping mechanism 35 clamps the carrier belt onto the buffer track 34, while the teeth on the rim of the buffer ratchet 31 can insert into the traction hole of the carrier belt, thereby pulling the carrier belt towards the direction of the tape feeding mechanism 2.
[0040] The portion of the carrier tape between the buffer assembly 3 and the tape assembly 2 is relaxed and droops into a U-shape under the action of gravity. The bottom end of the U-shaped structure is in the detection range of the first detector 42, and the top end of the U-shaped structure is in the detection range of the second detector 43.
[0041] When the carrier tape is not broken, the signals emitted by the first detector 42 and the second detector 43 are both blocked by the carrier tape, and the equipment operates normally at this time.
[0042] At the moment the carrier tape breaks, the carrier tape experiences a significant displacement on the buffer component 3, but this displacement is buffered by the slack section in the middle of the carrier tape. Subsequently, the end of the carrier tape leaves the detection range of the first detector 42.
[0043] When the end of the carrier tape leaves the detection range of the first detector 42, the signal emitted by the first detector 42 is received by the corresponding receiver, and the tape assembly 2 stops pulling the carrier tape.
[0044] If the abnormal stop signal causes the tape assembly 2 to continue operating, when the end of the carrier tape leaves the detection range of the second detector 43, the signal emitted by the second detector 43 will be received by the corresponding receiver, and the device will start to alarm.
