Description

Technical Field

[0001] This utility model relates to the field of semiconductor chip processing technology, specifically a cover tape conveyor with adjustable guide position. Background Technology

[0002] Carrier tape and cover tape are key components in electronic component packaging, primarily used for protecting, positioning, and transporting miniature components such as chips. The carrier tape acts as a support for the chip, securing it in its recessed slot and ensuring it doesn't slip or get damaged during transport and mounting. The cover tape covers the carrier tape's recessed slot, preventing contamination, electrostatic discharge, or physical impact to the chip. After the semiconductor chip is loaded onto the carrier tape, a heat-sealing device is used to heat-seal the cover tape onto it during transport. Existing cover tape transport devices were located far from the sealing blade, frequently resulting in cover tape misalignment during operation, posing a potential quality risk.

[0003] In view of the above-mentioned prior art, it is desirable to provide a cover tape conveyor with adjustable guide position to effectively reduce the frequency of plastic seal placement. Summary of the Invention

[0004] The purpose of this invention is to provide a cover belt conveyor with an adjustable guide position, which is easy to adjust, ensures no deviation of the cover belt during equipment operation, and eliminates potential quality problems.

[0005] A cover tape conveyor with adjustable guide position includes a worktable, a guiding mechanism, and an adjusting mechanism; The discharge end of the workbench is directly opposite the inlet of the external heat sealing device; The guiding mechanism includes a vertical plate, a traction wheel, and a pair of guide wheels; The vertical plate is located on one side of the workbench; The traction wheel is rotatably mounted on the upper front of the vertical plate, and the vertical plate is also equipped with a driving device for driving the traction wheel to rotate. A pair of guide wheels are rotatably arranged on the lower front of the vertical plate, one above the other; The adjustment mechanism is located at the discharge end of the workbench, and the adjustment mechanism includes a cover plate, an adjustment bolt, and a nut; The top inner wall of the cover plate contacts the upper surface of the workbench, and a limiting channel groove is provided in the middle of the top inner wall of the cover plate, the limiting channel groove passing through the left and right ends of the cover plate. The cover plate extends vertically downward on both sides to form extensions; The adjusting bolt is threaded onto the extension on the outside of the cover plate and is horizontally positioned. The end of the adjusting bolt passes through the extension and abuts against the side of the workbench. The nut is fitted onto the adjusting bolt.

[0006] Preferably, the cover plate is provided with at least two limiting grooves on the side away from the adjusting bolt, the limiting grooves penetrate through the top of the cover plate, and the limiting grooves are arranged along the axial direction of the adjusting bolt; Positioning posts are fixed at positions on the worktable directly opposite the limiting slide grooves, and the positioning posts pass vertically through the corresponding limiting slide grooves.

Detailed Implementation

[0012] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0013] A cover tape conveyor with adjustable guide position includes a worktable 1, a guiding mechanism and an adjusting mechanism.

[0014] like Figure 2 As shown, the discharge end of the workbench 1 is directly opposite the inlet of the external heat sealing device.

[0015] like Figure 1As shown, the guiding mechanism includes a vertical plate 2, a traction wheel 3, and a pair of guide wheels 4. The vertical plate 2 is located on one side of the workbench 1. The traction wheel 3 is rotatably mounted on the upper front of the vertical plate 2. The vertical plate 2 is also equipped with a driving device 5 for driving the traction wheel 3 to rotate. The pair of guide wheels 4 are rotatably mounted on the lower front of the vertical plate 2, with one wheel positioned above the other.

[0016] like Figure 2 and Figure 3 As shown, the adjustment mechanism is located at the discharge end of the workbench 1. The adjustment mechanism includes a cover plate 6, an adjusting bolt 7, and a nut 8. The top inner wall of the cover plate 6 contacts the upper surface of the workbench 1. A limiting channel groove 9 is provided in the middle of the top inner wall of the cover plate 6, and the limiting channel groove 9 passes through the left and right ends of the cover plate 6. The two sides of the cover plate 6 extend vertically downward to form extensions 10. The adjusting bolt 7 is threaded onto the extensions 10 on the outer side of the cover plate 6 and is set horizontally. The end of the adjusting bolt 7 passes through the extension 10 and abuts against the side of the workbench 1. The nut 8 is sleeved on the adjusting bolt 7.

[0017] Under the unwinding of the external unwinding device and the traction of the traction wheel 3, the cover tape passes through a pair of guide wheels 4 and enters the limiting channel groove 9 inside the cover plate 6. Finally, it enters the feed inlet of the heat sealing device. When it is necessary to adjust the position of the cover tape during transmission so that it accurately enters the feed inlet of the heat sealing device, the adjusting bolt 7 is rotated. The cover plate 6 moves closer to or further away from the head of the adjusting bolt 7 along the axial direction of the adjusting bolt 7, ultimately aligning the limiting channel groove 9 with the feed inlet of the heat sealing device. Finally, the nut 8 is tightened for better heat sealing of the carrier tape. The adjustment is simple, and the cover tape does not shift during equipment operation, eliminating potential quality problems.

[0018] In this embodiment, as Figure 3 As shown, at least two limiting grooves 11 are provided on the side of the cover plate 6 away from the adjusting bolt 7. The limiting grooves 11 penetrate the top of the cover plate 6 and are arranged along the axial direction of the adjusting bolt 7; Figure 2 As shown, positioning posts 12 are fixed at positions on the workbench 1 directly opposite the limiting slide grooves 11, and the positioning posts 12 vertically pass through the corresponding limiting slide grooves 11. This arrangement effectively ensures the straightness of the movement direction of the cover plate 6 when the adjusting bolts 7 adjust it, preventing it from deflecting. In this embodiment, there are two limiting slide grooves 11.

[0019] Furthermore, such as Figure 3 As shown, the cover plate 6 is provided with an elongated groove 13, which is located between two limiting sliding grooves 11 and extends through the top of the cover plate 6; Figure 2As shown, a fixing bolt 14 is vertically provided on the workbench 1. The fixing bolt 14 passes through the long groove 13 and is threaded onto the workbench 1. With this arrangement, after the cover plate 6 is adjusted to the correct position, the fixing bolt 14 is tightened downwards to effectively fix the cover plate 6, preventing the cover plate 6 from shifting due to vibration, and further ensuring the accuracy of the conveying direction of the cover belt.

[0020] In this embodiment, as Figure 1 As shown, a step portion 15 is provided on the workbench 1 near the cover plate. The side of the step portion 15 facing the cover plate 6 has a guide slope 16, which facilitates the conveying guide cover strip to be conveyed into the limiting channel groove 9 in the cover plate 6.

[0021] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
