The carrier tape 70 has grooves 702 along its length, and all holes are located in the grooves. The chips are placed in the holes of the carrier tape, and the cover tape is covered and bonded to the surface of the carrier tape to achieve chip packaging.

[0003] In the actual packaging process, the carrier tape is unwound through a reel. When the reel is unwound, another reel with the carrier tape is operated. At this time, the ends of the two carrier tapes need to be connected, and then the chips are placed and the cover tape is bonded.

[0004] Currently, the connection between the two carrier tapes is performed through manual intervention, in which the ends of the two carrier tapes are bonded together with tapes. This is inefficient and requires workers to always pay attention to the unwinding of the reel. The manual labor intensity is high, that is, the degree of automation is low. Summary of the invention

At the separation part, the tape roll is torn apart, and at this time, the tape roll moves along the upper surface of the tearing plate to the moving gap and bypasses the upper guide wheel, and is finally wound on the winding wheel; At the separation part, since the tape has a certain rigidity, it will not move with the bonding tape. When the tape is torn, the torn tape will gradually move to the upper glue plate with the movement of the tape until it is separated from the tape, thereby realizing the loading of the tape; the upper glue plate absorbs the tape, and then the third rotating cylinder drives the connecting plate to rotate 180 degrees, so that the upper glue plate faces downward, and the sixth cylinder drives the upper glue plate to descend, and the upper glue plate passes through the bonding notch, so that the tape can be bonded to the butt joint of the two carrier tapes, thereby realizing the continuation of the two carrier tapes.

[0023] By adopting the above technical scheme, in practice, the interior of the protrusion adopts the principle of a vacuum generator, that is, high-pressure gas is introduced into the air inlet, and the high-pressure gas is discharged from the air outlet, and negative pressure is formed at the adsorption hole to realize the adsorption action; when the tape on the tape roll is torn off, if the tape is deflected on the tape roll, the tape cannot be just overlapped on the protrusion, that is, the tape is tilted on the protrusion, which will affect the subsequent bonding effect between the two carriers, and in practice, even if the tape is deflected on the tape roll, the deflection angle is small. If it is large, the tape roll cannot be shipped out of the factory. After the tape is torn off, its end will move to the protrusion in an inclined state and will overlap on the correction wheel. The air outlet blows air outward to drive the correction wheel to rotate. The correction wheel will gradually correct the tape so that the tape gradually and completely overlaps on the protrusion.

[0025] By adopting the above technical solution, when the upper glue plate is facing upward, the linkage rod and the linkage rack are in a disengaged state. Under the action of the compression spring, the highest point of all correction wheels is flush with the surface of the protrusion, and the tape can be corrected at this time; the third rotating cylinder drives the connecting plate and the upper glue plate to rotate 180 degrees. During the rotation process, due to the gravity of the compression spring and the linkage plate, the linkage plate as a whole will move a certain distance in the lifting groove, that is, the highest point of the correction wheel will be higher than the surface of the protrusion; and at this time, the linkage rod also rotates synchronously on the cam surface. When the linkage rod is disengaged from the lowest point of the cam, the linkage rod slips, and the linkage rod is inserted into the penetration groove of the linkage rack, and under the cooperation of the first wedge surface and the second wedge surface, the linkage rack is driven to slide, and the linkage rack drives all the linkage gears to rotate, that is, the rotation of all correction wheels is realized. At this time, the side of the correction wheel is parallel to the side of the protrusion. At this time, all correction wheels can limit the tape. Because the third rotating cylinder rotates at a faster speed, the tape is prevented from being deflected due to inertia, thereby affecting the bonding effect.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Use the first cutter to cut off the tail end of the previous carrier tape, and the second cutter to cut off the beginning end of the next carrier tape to ensure the flatness of the joint of the two carrier tapes. When the two carrier tapes are butt-jointed, the joint is located at the bonding notch, and then the upper glue plate descends to bond the tape to the joint of the two carrier tapes to achieve the connection of the two carrier tapes; 2. When the latter carrier tape is conveyed, the two clamping plates will first clamp the carrier tape and move it to the second avoidance opening, so that the end of the carrier tape overlaps the avoidance area of ​​the first conveyor rail, and then the clamping plates are reset, the supporting plate rises, supports the carrier tape and contacts the pressure wheel, so the front end of the carrier tape has no traction, and the rotation of the pressure wheel drives the carrier tape to move forward a certain distance, and the detection of the positioning hole on the carrier tape by the detection switch can ensure that the carrier tape stops conveying after moving to the specified position, and then the plug pin is plugged into the positioning hole of the carrier tape, and then the plug pin drives the carrier tape to move a certain distance, so that the two carrier tapes can be docked, and the previous carrier tape is cut off at the tail end, and it is driven to move by the index wheel, because the index pin on the index wheel is plugged into the positioning hole in turn, and the moving distance of the previous carrier tape can be fixed by controlling the rotation angle of the index wheel, and the moving distance of the two carrier tapes can be controlled, so that the two carrier tapes can be smoothly docked; 3. The tape is wound on the unwinding wheel. After unwinding, the tape roll passes through the auxiliary wheel and then moves to the lower guide wheel. The tape roll passes through the moving gap and enters the moving groove of the tearing plate. Then it passes through the separation part. Under the action of the separation part, the tape and the roll tape are separated. The tape gradually moves to the protruding part of the upper rubber plate. The roll tape bypasses the upper guide wheel and is finally rolled up by the reel wheel. In this way, the tape is loaded; 4. If the tape in the tape roll is skewed to a certain extent, the tape will also be tilted when it is loaded onto the protruding part. The tape will overlap on the correction wheel. When air is ventilated to the air inlet, air will be ventilated outward at the air outlet, driving the correction wheel to rotate. The rotation of the correction wheel can gradually straighten the tape. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following combination Figure 2-Figure 17 This application is described in further detail.

[0030] The embodiment of the present application discloses a carrier tape splicing mechanism for chip packaging.

[0031] Example 1 Reference Figure 2The chip packaging carrier tape splicing mechanism includes a base 1, one end of the base 1 is the input end of the carrier tape, and the other end is the output end of the carrier tape. The base 1 is equipped with a first conveyor rail 2 and a second conveyor rail 3. The carrier tape passes through the first conveyor rail 2 and the second conveyor rail 3 from the input end to the output end in sequence. A first avoidance opening 31 is formed between the first conveyor rail 2 and the second conveyor rail 3. The base 1 is also rotatably provided with a first cutter 11 and a second cutter 12. The first cutter 11 is used to cut off the carrier tape at the input end, and what is cut here is the tail end of the previous carrier tape. The second cutter 12 is used to cut off the carrier tape located in the first avoidance opening 31, and what is cut here is the beginning end of the next carrier tape. The base 1 is located on the side of the first conveying rail 2 away from the second conveying rail 3 and is provided with a supporting plate 4 for lifting and lowering. A second avoidance opening 41 is formed between the supporting plate 4 and the first conveying rail 2. The base 1 is located on the upper side of the supporting plate 4 and is rotatably provided with a pressure wheel 5. The base 1 is also provided with a clamping plate 6 at the conveying end for sliding. The clamping plate 6 is used to clamp the starting end of the carrier and move it to the first conveying rail 2. The first conveying rail 2 is provided with a sliding groove 21. The base 1 is provided with a plug pin 7 for sliding. The plug pin 7 passes through the sliding groove 21 and is plugged into the positioning hole of the carrier and can drive the carrier to slide. The second conveying rail 3 is provided with a bonding notch 32. The butt joint of the two carriers is located at the bonding notch 32. The base 1 is located on the upper side of the bonding notch 32 and is provided with an upper glue plate 8 for lifting and lowering. The base 1 is also provided with a tape feeding assembly 9 for feeding the tape onto the upper glue plate 8, and the upper glue plate 8 absorbs and fixes the tape.

[0032] The input end of the carrier tape splicing mechanism is provided with a plurality of reels for winding the carrier tape. When the current carrier tape is about to be unwound, the first cutter 11 cuts off the tail end of the carrier tape to make the end of the carrier tape flat, and then the carrier tape continues to be conveyed forward until the bonding notch 32; at the same time, the clamping plate 6 clamps the beginning end of the next carrier tape and makes the carrier tape overlap on the first conveying rail 2, and then the clamping plate 6 is reset, the supporting plate 4 rises, supports the carrier tape, and makes the pressing wheel 5 press against the surface of the carrier tape. In practice, a driven wheel that rotates in cooperation with the pressing wheel 5 is also installed at the bottom of the supporting plate 4. The pressing wheel 5 and the driven wheel clamp the carrier tape, and then the pressing wheel 5 rotates to drive the next carrier tape to be conveyed forward. The carrier tape moves a certain distance until the beginning of the next carrier tape moves to the first avoidance opening 31. During the movement of the carrier tape, the detection switch will be used to detect the carrier tape positioning hole (relative to the position of the first or second carrier tape hole of the second cutter 12) to control the moving distance of the carrier tape. When the carrier tape moves to the first avoidance opening 31, the pressure wheel 5 stops working, and the second cutter 12 cuts off the beginning of the next carrier tape, making the end flat and convenient for subsequent docking with the previous carrier tape; then the plug pin 7 is plugged into the positioning hole and drives the carrier tape to move a certain distance, docking with the previous carrier tape, and then the upper glue plate 8 is lowered, so that the tape is bonded to the docking point of the two carrier tapes, and the two carrier tapes are connected. This method does not require manual intervention for bonding, which helps to improve the efficiency and automation of carrier tape connection.

[0034] After the two clamping plates 6 clamp the beginning of the carrier tape, the screw slide 13 drives the first mounting seat 10 to slide, thereby driving the carrier tape to move; at this time, the supporting plate 4 is in a descending state to avoid the sliding of the clamping plates 6. After the clamping plates 6 are reset, the supporting plate 4 rises to support the carrier tape. When the carrier tape needs to be cut, the sliding plate 103 drives the second mounting plate 1031 to slide, that is, drives the first cutter 11 to slide, and then the first rotating cylinder 1032 operates to achieve the cutting operation of the carrier tape.

The piston rod end of the third cylinder 2031 is fixedly connected to a pressure plate 2032. Because the beginning of the carrier tape may be bent, when the clamping plate 6 drives the carrier tape to overlap in the avoidance area 24, the supporting plate 4 rises to support the carrier tape, and then the pressing plate 2032 descends to flatten the carrier tape to facilitate subsequent transportation in the conveying trough 221.

[0038] When the pressing plate 2032 finishes the flattening operation on the carrier, the fifth cylinder 3031 drives the fifth mounting plate 3032 to descend, so that the plug pin 7 descends and plugs into the positioning hole of the carrier. Afterwards, the fourth cylinder 301 drives the L-shaped plate 303 to slide, so that the plug pin 7 drives the carrier to slide, thereby achieving the docking of the two carriers. Since the L-shaped plate 303 is fixed at a certain distance, the moving distance of the carrier is also fixed.

When the adhesive tape is loaded onto the upper glue plate 8, the third rotating cylinder 407 drives the connecting plate 50 to rotate 180 degrees, so that the upper glue plate 8 is downward, and then the sixth cylinder 405 drives the lifting plate 406 to descend, and the upper glue plate 8 passes through the bonding notch 32, so that the adhesive tape is bonded to the two carrier tapes, thereby realizing the connection of the two carrier tapes.

[0042] Reference Figure 2 and Fig.11The base 1 is located at the lower side of the second conveyor rail 3 and is installed with a seventh cylinder 17. The seventh cylinder 17 is arranged vertically upward. The piston rod end of the seventh cylinder 17 is fixedly connected with a positioning block 171. A plurality of positioning pins 172 are installed on the positioning block 171 in the vertical direction. In the present application, four positioning pins 172 are arranged. The four positioning pins 172 are plugged into the positioning holes at the joint of the two carriers. Each carrier corresponds to two positioning pins 172. After the two carriers are docked, and the accuracy of the position of the carrier holes is sensed by the detection switch, the seventh cylinder 17 drives the positioning block 171 to rise, and all the positioning pins 172 are plugged into the positioning holes on the two carriers to position and fix the two carriers to prevent the carriers from shifting during the bonding process, resulting in a decrease in the bonding effect.

[0043] A seventh mounting plate 18 is mounted on the base 1, and a second motor 181 is mounted on the seventh mounting plate 18. An index wheel 182 is coaxially fixed on the output shaft of the second motor 181. The index wheel 182 is located below the second conveying rail 3.

The index wheel 182 also has a plurality of index holes 1822 along its circumference, and the number of the index holes 1822 is the same as the number of the index pins 1821. When the index wheel 182 rotates, the carrier tape can be driven to move by the one-to-one cooperation between the index pin 1821 and the positioning hole. In practice, the movement distance of the carrier tape can be determined by detecting the movement amount of the index hole 1822 through the detection switch, and the carrier tape can be moved to the corresponding position to facilitate docking with the next carrier tape.

[0044] The implementation principle of the chip packaging carrier tape splicing mechanism of the embodiment of the present application is as follows: when the previous carrier tape is about to be unwound, the first cutter 11 cuts off the tail end of the previous carrier tape, and then the previous carrier tape continues to move forward until the tail end moves to the bonding notch 32 and stops; the clamping plate 6 clamps the beginning of the next carrier tape and drives its end to overlap the avoidance area 24 of the first conveyor rail 2, the clamping plate 6 is reset, the supporting plate 4 rises to support the carrier tape, and the pressing wheel 5 is pressed on the surface of the carrier tape, and then the pressing plate 2032 descends to press the next carrier tape The starting end is flattened, and then the pressing wheel 5 rotates, driving the carrier tape forward by friction until it is transported to the first avoidance port 31, and the second cutter 12 cuts off the starting end of the next carrier tape, making the end flat and convenient for docking with the end of the previous carrier tape; then the plug pin 7 is plugged into the positioning hole of the next carrier tape, and drives the next carrier tape to move and dock with the previous carrier tape, and then the third rotary cylinder 407 rotates, so that the upper glue plate 8 rotates downward, and then the upper glue plate 8 descends, and the tape is bonded to the docking point of the two carrier tapes to achieve the connection of the two carrier tapes. In this way, no manual intervention is required for bonding, which helps to improve the connection efficiency and automation level.

[0045] Example 2 Reference Fig.12 , Fig.13 and Fig.14 The difference between this embodiment and the first embodiment is that the upper glue plate 8 is formed with horizontal parts 82 on both sides of the protruding part 81, and the upper glue plate 8 is provided with two rows of correction wheels 821 in parallel at the two horizontal parts 82. The correction wheels 821 are arranged in an inclined manner, and the highest point of the correction wheel 821 is flush with the protruding part 81, and the highest point of the correction wheel 821 is located on the side of the protruding part 81. In practice, the adhesive tape on the roll may be skewed, but the degree of skewness is small. If the degree of skewness is large, the adhesive tape roll cannot be shipped. When the adhesive tape is skewed, the adhesive tape will overlap on the correction wheel 821. The correction wheel 821 rotates to correct the adhesive tape so that the adhesive tape is completely located on the protruding part 81.

[0046] The upper glue plate 8 is provided with an air inlet 83 at the end of the protruding portion 81, and an air outlet 84 is provided at the protruding portion 81 corresponding to the correction wheel 821, and the air outlet 84 faces the lower side of the correction wheel 821, and the air discharged from the air outlet 84 can drive the correction wheel 821 to rotate. The protruding portion 81 of the upper glue plate 8 adopts the principle of a vacuum generator, and high-pressure gas is introduced into the air inlet 83 and discharged from the air outlet 84, and then a vacuum negative pressure is generated at the adsorption hole 811. Since the principle of the vacuum generator is a conventional method, it will not be described in detail.

[0047] Reference Fig.12 and Fig.15 The lifting plate 406 is fixedly connected with a fixed shaft 4061 in the horizontal direction, and the fixed shaft 4061 is located in the connecting plate 50. A cam 4062 is fixedly connected to the fixed shaft 4061. The center of the cam 4062 is located on the rotation axis of the connecting plate 50, and the lowest point of the cam 4062 is located on the upper side; a lifting groove 85 is opened in the upper rubber plate 8, and the upper rubber plate 8 is slidably connected with a linkage plate 851 in the lifting groove 85. A plurality of ear plates 852 are rotatably connected to the linkage plate 851. The number of ear plates 852 is the same as the number of correction wheels 821 and corresponds one to one. The correction wheel 821 is rotatably connected to the protruding rod of the ear plate 852. The upper rubber plate 8 is located in the lifting groove 85 and is provided with a compression spring 853. The compression spring 853 is located at the lower side of the linkage plate 851. One end of the compression spring 853 is connected to the linkage plate 851, and the other end is connected to the inner wall of the lifting groove 85.

[0048] Reference Fig.15 and Fig.16, linkage gears 8521 are coaxially fixed on the ear plates 852, and sliding grooves 854 are opened on the opposite inner walls of the upper rubber plate 8. A linkage rack 60 is arranged in the upper rubber plate 8, and the two ends of the linkage rack 60 are located in the two sliding grooves 854 and slide with the sliding grooves 854. A return spring 855 is arranged in one of the sliding grooves 854, and one end of the return spring 855 is connected to the inner wall of the sliding groove 854, and the other end is connected to the end of the linkage rack 60; the linkage rack 60 is located between the two rows of ear plates 852, and the linkage rack 60 is a double-sided tooth, and the linkage rack 60 is meshed with all the linkage gears 8521.

[0049] When the upper glue plate 8 is facing upward, the compression spring 853 supports the linkage plate 851. When the upper glue plate 8 is rotated 180 degrees downward, under the action of the gravity of all structures on the linkage plate 851 and the extension of the compression spring 853 itself, the linkage plate 851 will slide a short distance in the lifting groove 85, that is, at this time, the highest point of the correction wheel 821 will be higher than the surface of the protrusion 81; and when the upper glue plate 8 is rotated 180 degrees downward, due to the rotational inertia, the tape may also be deflected. When the upper glue plate 8 rotates, the linkage rack 60 slides, driving all the linkage gears 8521 to rotate, so that all the correction wheels 821 rotate, and the side surfaces of the correction wheels 821 are parallel to the side surfaces of the protrusion 81. At this time, all the correction wheels 821 are located on the side edges of the protrusion 81, which can limit the tape, thereby preventing the tape from being deflected and ensuring the subsequent bonding effect.

[0050] Reference Fig.15 , Fig.16 and Fig.17 The upper rubber plate 8 is also provided with a linkage rod 86 that can be lifted and slid. The linkage rod 86 penetrates the connecting plate 50 and abuts against the surface of the cam 4062. A first wedge-shaped surface 861 is formed on the upper end of the linkage rod 86. A contact plate 862 is formed on the peripheral side of the linkage rod 86. A tension spring 87 is sleeved on the peripheral side of the linkage rod 86. The tension spring 87 is located on the lower side of the contact plate 862. One end of the tension spring 87 is connected to the contact plate 862, and the other end is connected to the inner wall of the lifting groove 85. A penetration groove 601 is opened in the middle of the linkage rack 60. A second wedge-shaped surface 602 is formed on the inner wall of the linkage rack 60 located at the penetration groove 601.

[0051] When the upper rubber plate 8 rotates 180 degrees, the linkage rod 86 rotates accordingly, and the linkage rod 86 moves on the surface of the cam 4062. When the linkage rod 86 is disengaged from the lowest point of the cam 4062, the linkage rod 86 slips, and the linkage rod 86 passes through the penetration groove 601 of the linkage rack 60. Under the action of the first wedge surface 861 and the second wedge surface 602, the linkage rack 60 can be driven to slide, thereby realizing the rotation of all correction wheels 821.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
