Description

Technical Field

[0001] The utility model relates to the technical field of integrated circuit chip test taping machines, in particular to a taping conveying device for integrated circuit chip test taping machines. Background Art

[0002] IC chip test taping machines are primarily used for back-end testing and packaging in the chip production process. They typically include a loading system, a testing system, and a taping system. First, the chips are sequentially transferred from the loading system to the testing system for parameter testing. After testing, the chips are transferred to the taping system, which loads qualified chips into the tape body to facilitate subsequent packaging and transportation. The tape is then transported via a conveyor chain to a hot melt machine, where the upper and lower tapes are heated and fused together for packaging before being reeled.

[0003] Current tape conveyors on the market often use a continuous rewinding method. Without a sound tension control system, the tape can experience inconsistent rewinding tension after hot-melt encapsulation. This inconsistency can cause the tape to curl and tangle during subsequent use, impacting chip encapsulation efficiency and quality. Existing devices on the market often rely on manual adjustment or simple mechanical limiters, and are unable to adaptively adjust tension.

[0004] Therefore, an integrated circuit chip test taping machine taping conveying device is needed to solve the above technical defects. Utility Model Content

[0005] The purpose of the present invention is to provide a tape conveying device for an integrated circuit chip test tape machine, so as to solve the problem of curling or winding caused by uneven tightness of the tape proposed in the above background technology.

[0006] The top end face of said sliding panel also is provided with an interlocking plate, and the interlocking plate is fixedly provided with a backing pin on the interlocking plate, and the interlocking plate is fixedly provided with a backing pin on the interlocking plate.

[0007] Preferably, a shaft sleeve is welded at the center of the rear end of the braiding disk, a rotating shaft is movably connected in the connecting frame, and the shaft sleeve and the rotating shaft are engaged and sleeved.

[0008] Preferably, the outer wall of the rotating shaft is processed with four sets of cams, and the inner wall of the sleeve is processed with four sets of keyways at corresponding positions.

[0009] Preferably, the tensioning guide wheel and the fixed guide wheel have the same size, and the tensioning guide wheel and the fixed guide wheel correspond to each other in the vertical direction.

[0010] Preferably, the rotating blade is a fan-shaped metal sheet, and the blocking block is fixed to the front end of the connecting plate and is 3 cm away from the vertical rotating plate.

[0011] Preferably, a conveying chain is installed at the front end of the fixed plate, a hot melt machine cover is provided above the conveying chain, a conveying guide wheel is provided on the left side of the conveying chain, the conveying guide wheel is movably connected to the fixed plate, the hot melt machine cover is fixedly connected to the fixed plate, and a groove is provided above the conveying guide wheel.

[0012] Preferably, the channel is a cover plate with two sides and a bottom open, an air cooler is installed at the top of the channel, and a filter is installed at the air outlet of the air cooler.

[0013] Preferably, the conveying guide wheel and the conveying chain are at the same horizontal height.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: the tape conveying device of the integrated circuit chip test tape machine not only reduces the curling or winding phenomenon caused by the uneven tightness of the tape through intermittent winding and self-adjusting tension, avoids the problem of material adhesion under high temperature conditions, but also reduces operational errors;

[0015] The belt conveyor is equipped with a rotating plate, a tensioning guide wheel, a guide seat, a guide groove, a block, a rotary piece, a tape disc, a dial, a rotating shaft, a toggle lever, a shaft sleeve, a driving motor and a filter screen. The conveying device transmits the belt to the hot melt machine cover plate through a transmission chain, passes through the hot melt sealing tape, comes to the groove for air cooling, and is downwardly introduced into the fixed guide wheel through the transmission guide wheel, and is transmitted to the guide seat through the tensioning guide wheel, passes through the guide groove and is wound onto the belt disc. At the rear end of the connecting frame, the dial is driven by the driving motor to rotate. The continuous rotation of the dial causes the toggle lever at the edge of the belt disc to be intermittently toggled, thereby winding the belt in an orderly manner. If the belt is too tight during the winding process, the rotating plate will be forced to swing towards the block direction, and the rotary piece will limit the swing range. The driving motor drives the dial to rotate, so that the belt disc winds the belt in an orderly manner. The design of intermittent winding and self-adjusting tensioning is used to ensure the orderliness of winding, reduce the curling or winding phenomenon caused by different tightness of the belt, and effectively improve the overall efficiency of testing and packaging.

[0016] The conveyor chain is equipped with a conveyor guide wheel, a trough, a cooling air blower, and a filter screen to transport the braid to the hot melt machine installed on the hot melt machine cover for hot melt sealing. Afterwards, the braid is quickly conveyed to the trough, and the external cooling air flow is introduced through the cooling air blower on the top and dust is removed and purified to ensure that the air flow blowing to the braid is clean and dust-free. After the cold air blows, the braid is cooled in time to avoid the problem of material sticking under high temperature conditions.

[0017] By providing a braiding reel, a shaft sleeve, and a rotating shaft, after the braiding reel has wound up a section of braid, the driving motor stops rotating, and the braiding reel is nested with the rotating shaft through the shaft sleeve. The engagement of the cross cam and the keyway ensures that the braiding reel will not become loose or misaligned during winding. The braiding reel can be manually pulled out and replaced with a new one, which reduces the possibility of operational errors. BRIEF DESCRIPTION OF THE DRAWINGS
