Description

Technical Field

[0001] The present application relates to the technical field of chip packaging, and in particular to an automatic conveying device for chip packaging. Background Art

[0002] Chip packaging is usually achieved using carrier tape and cover tape. The carrier tape carries the chip through periodic cavities and uses edge positioning holes to adapt to automated equipment. The cover tape covers the carrier tape and seals the cavity by adhesive or heat sealing to prevent the chip from falling and contamination and facilitate stripping and material removal by the placement machine.

[0003] Currently, carrier tape and cover tape are wound separately on trays, with multiple trays loaded into a single cassette. When packaging chips, workers must first remove the empty carrier and cover tape cassettes from their workstations before moving new ones to the next workstation. They must also remove the finished chip cassettes from their workstations before moving the empty ones back to their workstations. This constant back-and-forth movement of cassettes between multiple workstations during the chip packaging process results in low work efficiency and compromises chip packaging efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0041] The following is combined with Figures 1-10 This application is described in further detail.

[0042] The embodiment of the present application discloses an automatic conveying device for chip packaging.

[0043] Example 1:

[0044] Reference Figure 1 An automatic conveying device for chip packaging includes a storage rack 1. Multiple loading and unloading areas 2 are sequentially formed on one side of the storage rack 1 from top to bottom. Multiple working areas 3 are sequentially formed on the other side of the storage rack 1 from top to bottom. Two support plates 4 are fixedly mounted in each loading and unloading area 2 and working area 3 of the storage rack 1, with a gap 7 formed between the two support plates 4.

[0045] The width of the magazine 13 is greater than the width of the gap 7. The magazine 13 is placed on two support plates 4. Four positioning blocks 10 are fixedly mounted on each support plate 4. Each pair of positioning blocks 10 abuts against adjacent side walls at a corner of the magazine 13. The eight positioning blocks 10 on the two support plates 4 position the magazine 13 so that it does not move on the support plates 4.

[0046] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4A moving mechanism 5 is installed in the storage rack 1. The moving mechanism 5 consists of a lifting unit 51, a first translation unit 52, and a second translation unit 53. The lifting unit 51 is fixed in the storage rack 1. The first translation unit 52 is installed at the lifting end of the lifting unit 51. The second translation unit 53 is installed at the horizontally movable end of the first translation unit 52. The horizontally movable end of the second translation unit 53 is fixedly mounted with a support plate 6. The moving mechanism 5 can drive the support plate 6 to move freely in three-dimensional space.

[0047] The width of the support plate 6 is smaller than the width of the gap 7. Three positioning columns 8 are fixedly mounted on the support plate 6. The diameter of the top end of the positioning column 8 is smaller than the diameter of the bottom end. Three positioning holes 9 are opened on the bottom wall of the material box 13. The support plate 6 can drive the positioning columns 8 to move and insert into the positioning holes 9.

[0048] During the chip packaging operation, the peripheral automatic handling system (or staff) first places the empty chip cassette 13, the carrier tape cassette 13 filled with a tray, and the cover tape cassette 13 on the support plate 4 of the loading and unloading area 2. Subsequently, the moving mechanism 5 drives the pallet 6 to move, and the pallet 6 passes through the gap 7 from bottom to top and lifts the cassette 13. The pallet 6 transfers different types of cassettes 13 to the corresponding working area 3 respectively. The pallet 6 moves to just above the gap 7 and then moves downward. After the pallet 6 passes through the gap 7, the cassette 13 is placed on the two support plates 4 in the working area 3. After the chip is packaged, the moving mechanism 5 again moves the cassette 13 in the working area 3 back to the loading and unloading area 2 through the pallet 6. At this time, the peripheral automatic handling system (or staff) can replace the cassette 13 in the loading and unloading area 2. This operation method facilitates the rapid replacement of the cassette 13, effectively improving the chip packaging efficiency.

[0049] Specifically, the lifting portion 51 includes two lifting rails 511, a lifting slider 512, a first driving member 513, a screw 514, and a driving block 515. The two lifting rails 511 are fixedly mounted vertically within the storage rack 1. The two lifting sliders 512 are slidably mounted on the lifting rails 511 in the vertical direction. The lifting sliders 512 and the driving block 515 are both fixedly mounted on the first translation portion 52. The first driving member 513 is fixedly mounted within the storage rack 1. The screw 514 is rotatably mounted within the storage rack 1 and is fixedly connected to the driving end of the first driving member 513. The screw 514 threads through the driving block 515. In the present application, the first driving member 513 can optionally be a servo motor.

[0050] The first driving member 513 drives the screw 514 to rotate, the screw 514 drives the driving block 515 to move up and down, the driving block 515 drives the first translation part 52 to move up and down, and the first translation part 52 drives the lifting slider 512 to slide in the lifting track 511, so that the support plate 6 can move up and down stably.

[0051] The first translation unit 52 consists of a lifting plate 521, a second drive member 524, a drive belt 525, a clamping block 526, two first translation rails 522, and a first translation slider 523. The lifting plate 521 is fixedly mounted on the lifting slider 512 and the drive block 515, serving as a base support. The two first translation rails 522 are fixedly mounted on the sidewall of the lifting plate 521, away from the lifting slider 512. The first translation rails 522 are mounted horizontally and spaced apart vertically. The two first translation sliders 523 are slidably mounted on the two first translation rails 522 in the horizontal direction.

[0052] The transmission belt 525 is rotatably mounted on the lifting plate 521 and is located between the two first translation rails 522. The second driving member 524 is fixedly mounted on the lifting plate 521. The driving end of the second driving member 524 is connected to the transmission belt 525. In the present application, the second driving member 524 can be optionally a servo motor. The clamping block 526 clamps and fixes the transmission belt 525. The second translation portion 53 is fixedly connected to the first translation slider 523 and the clamping block 526. During operation, the second driving member 524 drives the transmission belt 525 to rotate, causing the clamping block 526 to translate, thereby moving the second translation portion 53 and causing the first translation slider 523 to slide stably on the first translation rail 522, thereby achieving smooth translation of the support plate 6.

[0053] The second translation unit 53 comprises a translation plate 531, a third driving member 534, two second translation rails 532, and a second translation slider 533. The translation plate 531 is fixedly connected to the clamping block 526 and the two first translation sliders 523, forming a unified support structure. The second translation rails 532 are horizontally fixedly mounted on the sidewall of the translation plate 531, away from the clamping block 526. The two second translation rails 532 are spaced apart horizontally.

[0054] Two second translation slides 533 are mounted horizontally and slideably on the two second translation rails 532, and the pallet 6 is fixed to the two second translation slides 533. A third driving member 534 is fixedly mounted on the translation plate 531. The driving end of the third driving member 534 is drivingly connected to the pallet 6. In this application, the third driving member 534 can be a pneumatic cylinder. During operation, the third driving member 534 is activated to drive the pallet 6 to translate. The pallet 6 simultaneously pulls the second translation slides 533 to slide on the second translation rails 532, thereby ensuring that the pallet 6 completes the translation movement smoothly and accurately.

[0055] The implementation principle of an automatic conveying device for chip packaging in an embodiment of the present application is as follows: During the chip packaging operation, the peripheral automatic handling system (or staff) first places the empty chip cassette 13, the carrier tape cassette 13 filled with chips, and the cover tape cassette 13 on the support plate 4 of the loading and unloading area 2. Subsequently, the moving mechanism 5 drives the pallet 6 to move, and the pallet 6 transfers different types of cassettes 13 to the support plate 4 of the corresponding working area 3. After the chip is packaged, the moving mechanism 5 again moves the cassette 13 in the working area 3 back to the loading and unloading area 2 through the pallet 6. At this time, the peripheral automatic handling system (or staff) can replace the cassette 13 in the loading and unloading area 2. This operation method facilitates the rapid replacement of the cassette 13, effectively improving the chip packaging efficiency.

[0056] Example 2:

[0057] Reference Figure 5 、 Figure 6 、 Figure 7 and Figure 8 This embodiment differs from Example 1 in that a locking block 11 is horizontally slidably mounted within each positioning post 8. A first elastic member 15 is mounted within the positioning post 8. The first elastic member 15 abuts against the locking block 11 and pushes one side of the locking block 11 out of the positioning post 8. The top end of the locking block 11, located outside the positioning post 8, is chamfered 14. A locking groove 12 is formed on the inner wall of the positioning hole 9 of the magazine 13. In this application, the first elastic member 15 can be a spring.

[0058] Three first racks 16 are slidably mounted within the support plate 6. The three first racks 16 are fixedly connected to the bottoms of the three locking blocks 11 via connecting rods 27. Three transmission gears 17 are rotatably mounted within the support plate 6. The three transmission gears 17 respectively mesh with the three first racks 16. Three second racks 18 are slidably mounted within the support plate 6. The second racks 18 are parallel to the first racks 16 and mesh with the three transmission gears 17 respectively.

[0059] Reference Figure 9 and Figure 10 Three eccentric wheels 19 are rotatably mounted on the two side walls of the support plate 6 in the horizontal direction. The three eccentric wheels 19 are respectively located above the ends of the three second racks 18. A plurality of teeth 21 are fixedly mounted at equal intervals on the outer wall of the eccentric wheel 19 at the eccentric position. A second elastic member 20 is installed at the rotational connection between the eccentric wheel 19 and the support plate 6. In this application, the second elastic member 20 can be selected as a torsion spring. When the eccentric wheel 19 rotates, the second elastic member 20 can drive the eccentric wheel 19 to rotate and reset.

[0060] A trigger member 22 is mounted on the eccentric wheel 19. The trigger member 22 includes a first rod 221, a second rod 222, and a third elastic member 223. The first rod 221 is fixedly mounted on the side wall of the eccentric wheel 19, the second rod 222 is rotatably mounted on the end of the first rod 221 away from the eccentric wheel 19, and the third elastic member 223 is mounted at the rotatable connection between the second rod 222 and the first rod 221. In the present application, the third elastic member 223 can be a torsion spring. When the second rod 222 rotates, the third elastic member 223 can drive the second rod 222 to rotate and reset.

[0061] A first limiting block 23 is fixedly mounted on the eccentric 19. A first arc-shaped limiting groove 24 is defined within the support plate 6. The first limiting block 23 is slidably mounted within the first limiting groove 24. When the first rod 221 rotates upward, the first rod 221 drives the eccentric 19 to rotate, which in turn drives the first limiting block 23 to slide within the first limiting groove 24. The eccentric 19 then drives the toothed body 21 to rotate and engage with the second rack 18. The second elastic member 20 then drives the eccentric 19 to rotate and reset. When the first rod 221 rotates downward, the first rod 221 drives the first limiting block 23 via the eccentric 19. At this point, the first limiting block 23 is located at the end of the first limiting groove 24. The first limiting groove 24 limits the first limiting block 23, preventing the first rod 221 from rotating downward.

[0062] A second limiting block 25 is fixedly mounted on the second rod 222. A second arc-shaped limiting groove 26 is defined within the first rod 221, and the second limiting block 25 is slidably mounted within the second limiting groove 26. When the second rod 222 rotates downward, the second rod 222 drives the second limiting block 25 to slide within the second limiting groove 26. Subsequently, the third elastic member 223 drives the second rod 222 to rotate and return to its original position. When the second rod 222 rotates upward, the second rod 222 drives the second limiting block 25 to move. At this point, the second limiting block 25 is located at the end of the second limiting groove 26. The second limiting groove 26 limits the second limiting block 25, preventing the second rod 222 from rotating upward.

[0063] The implementation principle of Example 2 of the present application is: when the bracket moves upward through the gap 7, the end of the second rod body 222 will contact the bottom wall of the support plate 4, the first limit block 23 limits the first rod body 221 from rotating downward, and the second rod body 222 rotates downward on the first rod body 221. The first rod body 221 will not drive the eccentric wheel 19 to rotate. At this time, the tooth body 21 is not in contact with the second rack 18.

[0064] Under the action of the chamfer 14, the material box 13 pushes the locking block 11 to slide into the positioning column 8. When the bracket supports the material box 13, the positioning column 8 is inserted into the positioning groove, and then the first elastic member 15 pushes the locking block 11 to slide into the locking groove 12, thereby locking the material box 13 so that the material box 13 will not move.

[0065] When the bracket moves downward and passes the support plate 4, the end of the second rod body 222 contacts the top wall of the support plate 4, and the second limit block 25 limits the second rod body 222 from rotating upward, so that the second rod body 222 drives the first rod body 221 to rotate upward, and the first rod body 221 drives the eccentric wheel 19 to rotate, so that the tooth body 21 engages with the second tooth body 21, and the tooth body 21 drives the second rack 18 to move, and the second rack 18 drives the first rack 16 to move through the transmission gear 17, and the first rack 16 drives the locking block 11 to slide out of the locking groove 12, so that the material box 13 can be separated from the bracket.

[0066] The above are merely optional embodiments of the present disclosure and are not intended to limit the present disclosure. Those skilled in the art will readily appreciate that the present disclosure may be modified and varied in various ways. Any modifications, equivalent substitutions, improvements, and the like made within the spirit and principles of the present disclosure shall be included within the scope of protection of the present disclosure.
