Description

Technical Field

[0001] The present invention relates to the technical field of IC chip tape conveying, and particularly to an IC chip tape conveying device. Background Art

[0002] With the rapid development of the information age, the IC chip industry will gradually occupy the vast majority of the market. However, in order to better improve production capacity to meet market demand, which is the future breakthrough point for IC chips. As an accessory for the main functions of the chip, the lead frame must ensure its stable and mature production process so as to meet the large market demand for chips. One of the processes in chip packaging (wire bonding) is to electrically connect the chip and the pins of the lead frame through gold / copper wires. In order to stabilize the wire bonding process and avoid the defect of pin offset in the packaging process, non-conductive tapes are added to the lead frame design to fix the pins.

[0003] Most of the existing IC chip tapes are made of plastic composite materials and have micro-static electricity. If the original tape carrier with a large contact area and the carrier of the conveying device made of metal material are used to convey the tape, it will be very easy to generate static electricity on the tape and adsorb it on the carrier, resulting in the tape being not smooth during the conveying process, and then it may lead to the situation of missing tape or narrow tape in the later stage of IC chips, that is, reducing the use efficiency of the tape conveying device.

[0004] Therefore, we propose a new type of IC chip tape conveying device to solve the problems mentioned above. Summary of the Invention

[0034] According to Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 and Figure 8As shown, a dust removal mechanism 2 is provided on the conveying mechanism 1.

Two electric push rods 202 are installed on the top of the top plate 201, which facilitates the movement operation of the dust collection hood 204 under the cooperation of the electric push rods 202 and the hollow blocks 203.

[0035] According to Figure 2 、 Figure 4 and Figure 8 As shown, the telescopic ends of the two electric push rods 202 both movably penetrate through the top of the top plate 201.

The first concave block 205 is fixed to the front surface of the second U-shaped block 102, which facilitates the protection of the small fan 207 inside it under the cooperation of the first concave block 205 and the second concave block 208.

[0036] According to Figure 2 、 Figure 4 and Figures 6-8 As shown, first cylindrical holes 206 are provided on the inner walls of both the first concave block 205 and the second U-shaped block 102, and the interiors of the two first cylindrical holes 206 are connected. Two small fans 207 are installed on the inner wall of the first concave block 205. A second concave block 208 is provided on the front surface of the first concave block 205, which facilitates the collection and storage operation of the dust left after gas filtration under the action of the second concave block 208.

[0037] According to Figure 2 、 Figure 4 、 Figure 6 and Figure 7 As shown, a hollow plate 209 is provided on the front surface of the second concave block 208. Fixing screws 212 movably penetrate through the four corners of the front surface of the hollow plate 209. One ends of the four fixing screws 212 are all threadedly connected to the front surface of the first concave block 205. Two second cylindrical holes 211 are provided on the inner wall of the second concave block 208, which facilitates the diversion of the dust-laden gas diverted by the small fan 207 into the interior of the second concave block 208 under the action of the second cylindrical holes 211.

[0038] According to Figure 2 、 Figure 4 、 Figure 6 and Figure 7As shown, the output ends of two small fans 207 are respectively movably sleeved inside two second cylindrical holes 211. The input ends of the two small fans 207 are respectively connected to the output ends of two dust collection hoods 204 through hoses. A dust-proof net 210 is installed inside the hollow plate 209, which facilitates filtering the dust in the dust-laden gas diverted by the small fan 207 under the action of the dust-proof net 210 and leaving it inside the second concave block 208.

[0039] According to Figure 1 、 Figure 2 、 Figure 4 and Figure 8 As shown, a high-voltage generator 3 is installed on the rear surface of the second U-shaped block 102. Two symmetrically arranged L-shaped frames 4 are fixed to the top of the inner wall of the first U-shaped block 101. An electrostatic eliminator rod 5 is installed between the two L-shaped frames 4, which facilitates removing the static electricity on the sticker tape under the cooperation of the high-voltage generator 3 and the electrostatic eliminator rod 5.

[0040] According to Figure 1 、 Figure 4 and Figure 8 As shown, the electrostatic eliminator rod 5 is electrically connected to the high-voltage generator 3. Two mounting blocks 6 are fixed to the front and rear surfaces of the second U-shaped block 102, which facilitates stably fixing the conveying device to the equipment or workbench in use under the action of the mounting blocks 6.

[0041] The effect achieved by the entire mechanism is as follows: When it is necessary to convey the IC chip tape, first directly loosen all the hand-tightening bolt rods 110. Then, according to the width of the tape, directly horizontally move all the limit blocks 107 through the cooperation of the limit slots 106 to adjust the distance between every two limit blocks 107 in each group. When each limit block 107 moves in sequence, each moving limit block 107 will directly drive the connected hand-tightening bolt rod 110 to move horizontally under the cooperation of the corresponding sliding hole 108. When the distance between every two limit blocks 107 in each group is adjusted, directly tighten all the hand-tightening bolt rods 110. When all the hand-tightening bolt rods 110 cannot be tightened anymore, each hand-tightening bolt rod 110 will, under the cooperation of the corresponding rectangular plate 105, fix the corresponding limit block 107. Then loosen the fixing bolts 115 on each rotating rod 113, and then adjust the distance between the two rings 114 on each rotating rod 113 according to the width of the tape. When all the rings 114 move to the designated positions, directly tighten the fixing bolts 115 on each ring 114. When each fixing bolt 115 is tightened, each ring 114 will be directly fixed on the corresponding rotating rod 113 under the cooperation of the corresponding fixing bolt 115. After that, connect the motor 109, two electric push rods 202, two small air blowers 207, and the high-voltage generator 3 to the external power distribution box. When everything is ready, the staff can directly pass one end of the tape to be conveyed through between the opposite sides of every two rings 114 in sequence, between the opposite sides of each group of limit blocks 107, and between the outer surfaces of two of the driving rollers 103. Then directly start the motor 109. At this time, the started motor 109 will drive the connected driving roller 103 to rotate, and the rotating driving roller 103 will directly drive the tape to move under the cooperation of the corresponding driving roller 103. At this time, when the tape is moving, due to the small contact area with the rotating rod 113 and the ring 114, that is, the resistance is small, the generation of static electricity is reduced, so that the tape can be smoothly conveyed, that is, to avoid problems such as narrow tape and missed pasting during the later operation of pasting the IC chip on the tape. At the same time, under the cooperation of the ring 114 and the limit block 107, the tape running deviation is restricted, so that the tape can be accurately conveyed. When the tape is being conveyed, in order to prevent dust from falling on the tape during the movement and affecting the later operation of pasting the IC chip on the tape, directly start the two electric push rods 202 synchronously at this time. Each started electric push rod 202 will directly drive the corresponding dust collection cover 204 to move under the cooperation of the connected hollow block 203. When the bottoms of the two dust collection covers 204 almost completely touch the top of the moving tape, directly stop the two electric push rods 202. Then start the two small air blowers 207 synchronously. Each started small air blower 207 will directly make the input end of the corresponding dust collection cover 204 obtain suction under the cooperation of the corresponding hose,At this time, each dust collection hood 204 that obtains suction will suck away the dust on the top of the tape passing through the dust collection hood 204. Then, the sucked dust will be directly diverted into the interior of the second concave block 208. After that, the gas diverted into the interior of the second concave block 208 will directly pass through the mesh holes of the dust-proof net 210, while the dust will be left inside the second concave block 208. When it is necessary to remove a small amount of static electricity that may be generated during the movement of the tape, the high-voltage generator 3 is directly started at this time. The started high-voltage generator 3 will use air ionization to generate a large number of positive and negative charges, and with the cooperation of the static eliminator bar 5, directly neutralize the charges carried on the surface of the tape, thereby achieving the operation of removing static electricity from the tape.

[0042] Among them, the motor 109, the electric push rod 202, the small fan 207, the high-voltage generator 3, and the static eliminator bar 5 are all prior arts and will not be explained in detail here.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
