Description

Technical Field

[0001] This utility model relates to the field of semiconductor packaging tape technology, and more specifically, to a traction and winding device for semiconductor packaging tape. Background Technology

[0002] Semiconductor tapes are mainly used in the processing of semiconductor wafers such as silicon and glass. During the wafer grinding and cutting process, the wafer is fixed by high adhesion. After processing, the adhesion will weaken after being irradiated by ultraviolet (UV) light, making it easier to peel off the tape and pick up the chip. The tape needs to be pulled and wound up during processing.

[0003] To address the shortcomings of existing technologies, in current semiconductor packaging tape traction devices, the ends of the semiconductor packaging tape are not easily secured before traction, leading to frequent winding failures during initial traction. Furthermore, the side shields on winding drums are typically integrated with the drum, making them difficult to remove and subsequently hindering tape roll extraction. On the other hand, winding drums without side shields are prone to tape misalignment during traction and winding, resulting in winding errors. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a traction and winding device for semiconductor packaging tape.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a traction and winding device for semiconductor packaging tape, comprising an L-shaped base, a fixing ring fixedly connected to the side wall of the L-shaped base, a winding drum rotatably connected to the inner wall of the fixing ring, and the winding drum rotatably connected to the L-shaped base, symmetrically distributed through slots on the upper and lower sides of the winding drum along the axial direction, centrally symmetrically distributed clamping plates slidably connected to both sides of the winding drum, an arc-shaped piston rod fixedly connected to one side of the clamping plate extending into the winding drum, an arc-shaped piston cylinder slidably connected to the outer wall of the arc-shaped piston rod, and the arc-shaped piston cylinder having a hollow structure, the end of the arc-shaped piston cylinder away from the arc-shaped piston rod (13) being connected to the winding drum. The winding drum has a fixed connection to the side wall of the through groove, and a mounting plate is fixedly connected to the inner wall of the winding drum. A symmetrically distributed support plate is fixedly connected to one side of the mounting plate. A double-ended screw is rotatably connected to the inner wall of the support plate. Both ends of the double-ended screw are threaded with threaded sleeves, and the threaded sleeves are slidably connected to the mounting plate. A push plate is fixedly connected to the ends of the two threaded sleeves that are far apart from each other. An air bladder is fixedly connected to the end of the push plate that is far away from the threaded sleeve. The two air bladders are centrally symmetrically distributed and fixedly connected to the inner wall of the winding drum. A conveying pipe is fixedly connected to the end of the air bladder that is far away from the push plate, and the conveying pipe is connected to the inside of the arc-shaped piston cylinder. A baffle is installed at the end of the winding drum that is far away from the fixed ring.

[0006] As a preferred technical solution of this utility model, the side of the baffle near the winding drum is fixedly connected with symmetrically distributed positioning blocks, and the positioning blocks are adapted to the through groove. A limiting groove is opened in the positioning block, and a limiting rod is fixedly connected to the bottom of the clamping plate, and the limiting rod is adapted to the limiting groove.

[0007] As a preferred embodiment of this utility model, a driven bevel gear is fixedly sleeved on the outer wall of the bidirectional screw, and a driving bevel gear meshes with one side of the driven bevel gear. A second motor is fixedly connected to the mounting plate, and the output shaft of the second motor is fixedly connected to the driving bevel gear.

[0008] As a preferred embodiment of this utility model, a sliding groove is provided on the side of the fixed ring near the baffle, a guide rod is fixedly connected to the inner wall of the sliding groove, a movable block is slidably connected to the outer wall of the guide rod, and the movable block is slidably connected to the inner wall of the sliding groove. A stop bar is fixedly connected to the side of the movable block near the baffle.

[0009] As a preferred embodiment of this utility model, a spring is fixedly connected to the top of the movable block, and the other end of the spring is fixedly connected to the top of the slide groove. The spring is sleeved with the guide rod.

[0010] As a preferred embodiment of this utility model, a first motor is fixedly connected to the L-shaped base, and the output shaft of the first motor is fixedly connected to the winding drum.

[0011] As a preferred technical solution of this utility model, a control panel is provided on one side of the winding drum and fixedly connected to the L-shaped base. The control panel is electrically connected to the first motor and the control panel is electrically connected to the second motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, during installation, the baffle is pushed so that the positioning block on the baffle enters the through groove. When the baffle abuts against the winding drum, the limiting rod aligns with the limiting groove. At this time, the second motor is started through the control panel. The output shaft of the second motor rotates, driving the active bevel gear to rotate, which in turn drives the driven bevel gear to rotate, causing the bidirectional screw to rotate. The rotation of the bidirectional screw drives the two threaded sleeves to move toward the side that is far apart from each other. The threaded sleeves drive the push plate to move, which in turn squeezes the airbag. The gas in the airbag enters the arc-shaped piston cylinder through the delivery pipe, which in turn pushes the arc-shaped piston rod to move. The arc-shaped piston rod drives the clamping plate to move. When the clamping plate moves, it drives the limiting rod to move, so that the limiting rod enters the limiting groove to limit the positioning block. This facilitates the installation and disassembly of the baffle and facilitates the baffle to limit the semiconductor packaging tape during winding, preventing the semiconductor packaging tape roll from moving.

[0014] 2. In this invention, during the traction process, the stop bar contacts the semiconductor packaging tape, allowing the stop bar to smooth the wound semiconductor packaging tape and prevent wrinkles from forming during winding.

[0015] 3. In this utility model, during traction, the end of the semiconductor encapsulation tape is placed into the through slot, and the second motor is started through the control panel to continue running. At this time, the second motor causes the push plate to continue to squeeze the airbag, causing the clamping plate to move further until the clamping plate fixes the end of the semiconductor encapsulation tape. Then, the first motor can be started through the control panel, causing the output shaft of the first motor to rotate and drive the winding drum to rotate, thereby winding the semiconductor encapsulation tape, making the tape firmly fixed and the winding convenient and efficient.

[0026] like Figures 1 to 8 As shown, this utility model provides a traction and winding device for semiconductor packaging tape, including an L-shaped base 1. A fixing ring 4 is fixedly connected to the side wall of the L-shaped base 1. A winding drum 5 is rotatably connected to the inner wall of the fixing ring 4. The upper and lower sides of the winding drum 5 are symmetrically distributed through slots 11 along the axial direction. The sides of the winding drum 5 are slidably connected to centrally symmetrically distributed clamping plates 12. An arc-shaped piston rod 13 is fixedly connected to one side of the clamping plate 12 that extends into the through slot of the winding drum 5. An arc-shaped piston cylinder 14 is slidably connected to the outer wall of the arc-shaped piston rod 13. The arc-shaped piston cylinder 14 has a hollow structure. The end of the arc-shaped piston cylinder 14 away from the arc-shaped piston rod 13 is fixedly connected to the side wall of the through slot of the winding drum 5. A mounting plate 20 is fixedly connected to the inner wall of the winding drum 5. A symmetrically distributed support plate is fixedly connected to one side of the mounting plate 20. A bidirectional screw 19 is rotatably connected to the inner wall of the support plate. The outer walls of both ends of the bidirectional screw 19 are... Both threaded sleeves 18 are threadedly connected and slidably connected to the mounting plate 20. That is, the threaded sleeves 18 slide in the groove of the mounting plate 20 via a moving plate. Push plates 17 are fixedly connected to the ends of the two threaded sleeves 18 that are far apart from each other. Airbags 16 are fixedly connected to the end of the push plates 17 that is far away from the threaded sleeves 18. The two airbags 16 are centrally symmetrically distributed and fixedly connected to the inner wall of the take-up drum 5. A delivery pipe 15 is fixedly connected to the end of the airbag 16 that is far away from the push plate 17. The delivery pipe 15 passes through the inner wall of the take-up drum 5 and communicates with the inside of the arc-shaped piston cylinder 14. A baffle 6 is installed at the end of the take-up drum 5 that is far away from the fixing ring 4. The threaded sleeves 18 are moved by the bidirectional screw 19, which compresses the airbags 16. The gas enters the arc-shaped piston cylinder 14 through the gas delivery pipe 15 and pushes the arc-shaped piston rod 13, so that the clamping plate 12 fixes the semiconductor packaging tape.

[0027] A symmetrically distributed positioning block 24 is fixedly connected to the side of the baffle 6 near the winding drum 5, and the positioning block 24 is adapted to the through groove 11. A limiting groove 26 is opened in the positioning block 24. A limiting rod 25 (including a fixing part and a positioning part) is fixedly connected to the inner side wall of the clamping plate 12 near the end, and the positioning part of the limiting rod 25 is adapted to the limiting groove 26. The limiting rod 25 and the limiting groove 26 cooperate to facilitate the installation of the baffle 6.

[0028] A driven bevel gear 23 is fixedly sleeved on the outer wall of the bidirectional screw 19. A driving bevel gear 22 meshes with one side of the driven bevel gear 23. A second motor 21 is fixedly connected to the mounting plate 20. The output shaft of the second motor 21 is fixedly connected to the driving bevel gear 22. The cooperation between the driving bevel gear 22 and the driven bevel gear 23 enables the output shaft of the second motor 21 to drive the bidirectional screw 19 to rotate.

[0029] A groove is provided on the side of the fixed ring 4 near the baffle 6. A guide rod 9 is fixedly connected to the inner wall of the groove. A movable block 7 is slidably connected to the outer wall of the guide rod 9, and the movable block 7 is slidably connected to the inner wall of the groove. A stop bar 8 is fixedly connected to the side of the movable block 7 near the baffle 6. The stop bar smooths the rolled semiconductor packaging tape to prevent wrinkles.

[0030] A spring 10 is fixedly connected to the top of the movable block 7, and the other end of the spring 10 is fixedly connected to the top of the slide groove. The spring 10 is sleeved with the guide rod 9. The spring 10 facilitates the contact between the stop rod 8 and the semiconductor packaging tape, and facilitates the reset of the stop rod 8.

[0031] A first motor 2 is fixedly connected to the L-shaped base 1, and the output shaft of the first motor 2 is fixedly connected to the take-up drum 5. The first motor 2 drives the take-up drum 5 to take up the semiconductor packaging tape.

[0032] The winding drum 5 has a control panel 3 fixedly connected to the L-shaped base 1 on one side. The control panel 3 is electrically connected to the first motor 2 and the second motor 21. The operation of the first motor 2 and the second motor 21 is controlled by the control panel 3.

[0033] Working principle and usage process of this utility model:

[0034] In this application, during installation, the baffle 6 is pushed so that the positioning block 24 on the baffle 6 enters the end of the through groove 11. When the baffle 6 abuts against the winding drum 5, the limiting rod 25 aligns with the limiting groove 26. At this time, the second motor 21 is started through the control panel 3. The output shaft of the second motor 21 rotates, driving the driving bevel gear 22 to rotate, which in turn drives the driven bevel gear 23 to rotate, causing the bidirectional screw 19 to rotate. The rotation of the bidirectional screw 19 causes the two threaded sleeves 18 to move toward a side that is far apart from each other. 8 drives the push plate 17 to move, thereby squeezing the airbag 16, so that the gas in the airbag 16 enters the arc-shaped piston cylinder 14 through the delivery pipe 15, thereby pushing the arc-shaped piston rod 13 to move, so that the arc-shaped piston rod 13 drives the clamping plate 12 to move, and when the clamping plate 12 moves, it drives the limiting rod 25 to move, so that the limiting rod 25 enters the limiting groove 26 to limit the positioning block 24, which facilitates the installation and removal of the baffle 6, and facilitates the baffle 6 to limit the semiconductor packaging tape during winding, so as to prevent the semiconductor packaging tape roll from moving;

[0035] During installation, the threaded sleeve 18 moves but does not complete its travel, causing the limiting rod 25 to enter the limiting groove 26.

[0036] In this application, during traction, the end of the semiconductor encapsulation tape is placed into the through slot 11, and the second motor 21 is started through the control panel 3 to continue running. At this time, the second motor 21 causes the push plate 17 to continue to squeeze the airbag 16, causing the clamping plate 12 to move further until the clamping plate 12 clamps and fixes the end of the semiconductor encapsulation tape. Then, the first motor 2 is started through the control panel 3, causing the output shaft of the first motor 2 to rotate and drive the winding drum 5 to rotate, thereby winding the semiconductor encapsulation tape.

[0037] In this application, during the traction process, the stop bar 8 contacts the semiconductor packaging tape, so that the stop bar 8 smooths the wound semiconductor packaging tape and avoids wrinkles when the semiconductor packaging tape is wound.
