Description

Technical Field

[0001] The invention relates to the technical field of frame film peeling, and in particular to a double-sided flexible lead frame film peeling device. Background Art

[0002] Flexible lead frame, also known as IC card packaging frame or carrier tape, is a key dedicated base material for smart card chip packaging, generally composed of metal leads and insulating coating. Metal leads have good conductivity and flexibility, while insulating coating plays an insulating and protective role, ensuring electrical isolation between leads and between leads and the external environment. Flexible lead frames can generally be divided into two categories: double-sided flexible lead frames and single-sided flexible lead frames. Unlike single-sided flexible lead frames, double-sided flexible lead frames have metal leads and corresponding circuit patterns on both sides, and can connect chips or other electronic components on both sides at the same time, increasing the flexibility and integration of connections.

[0003] During the production, transportation and storage of double-sided flexible lead frames, protective films are usually applied to both the upper and lower surfaces to protect the surface from contamination, scratches or oxidation. Before subsequent chip bonding, packaging and other processes, these protective films need to be removed by a film removal device to ensure the cleanliness of the lead frame surface and good electrical connection performance, and to avoid affecting the bonding quality or causing a decrease in electrical performance due to the presence of the protective film.

[0004] For example, a lead frame double-sided film peeling system with Chinese patent publication number CN114121736B includes several automatic loading devices, automatic material moving devices, material conveying devices and automatic film peeling devices. Several automatic loading devices are arranged side by side inside the automatic material moving device, and the feeding end of the material conveying device is arranged at the other end of the automatic material moving device. The discharging end of the material conveying device extends to the automatic film peeling device, and the discharging port of the automatic film peeling device faces the existing etching production line. The automatic film peeling device includes a conveying unit and a film peeling unit. The conveying unit faces the discharging end of the material conveying device, and the film peeling unit is arranged directly above the conveying unit.

[0005] This solution can automatically peel off the film on the upper and lower surfaces of the lead frame at the same time through the damping effect, reducing the labor intensity of workers. However, it is not convenient to peel off the film on the flexible lead frame. The flexible lead frame will bend when subjected to force, resulting in friction that cannot stably peel off the film, and the success rate is low. In addition, excessive friction can easily cause the flexible lead frame to be excessively bent and damaged, resulting in poor film peeling quality. Summary of the invention

[0044] like Figures 1 to 12 As shown:

[0045] A double-sided flexible lead frame film peeling device, including a base 1 and a frame 10, the bottom of the frame 10 is fixedly connected to the top of the base 1, and also includes an operating table 11, a fixed flip assembly 2, a film blowing and peeling assembly 3 and a driving assembly 4, the bottom of the operating table 11 is fixedly connected to the top of the base 1, the top of the operating table 11 is provided with a through empty slot 110, the empty slot 110 is communicated with the inside of the base 1, the fixed flip assembly 2 includes a fixed plate 20 and a pair of clamping mechanisms 21, the fixed plate 20 is rotatably installed on the top of the operating table 11, the top of the fixed plate 20 is provided with a through placement slot 200, the inner wall of the placement slot 200 is a stepped structure, and the bottom wall of the placement slot 200 is connected to the bottom of the frame body 14 The two clamping mechanisms 21 are symmetrically installed at both ends of the fixed plate 20, and the clamping mechanisms 21 are used to fix the frame body 14. The film blowing and peeling assembly 3 includes a pair of swing arms 30, a pair of support frames 31, a high-pressure nozzle 32 and a scraper 33. The swing arm 30 is rotatably installed on the operating table 11, and the support frame 31 is slidably installed on the swing arm 30. The two ends of the high-pressure nozzle 32 are respectively slidably connected to the two support frames 31, and the two ends of the scraper 33 are respectively fixedly connected to the two support frames 31. The two sides of the bottom of the scraper 33 are respectively in contact with the frame body 14 and the protective film 15. The driving assembly 4 is installed on the operating table 11, and the driving assembly 4 is used to drive the fixed plate 20 and the swing arm 30 to rotate.

[0046] When removing the film, first move the frame body 14 to the top of the fixed plate 20 through the conveying component 5 and place it in the placement groove 200, so that the edge of the frame body 14 abuts against the bottom wall of the placement groove 200. At this time, there are gaps between the protective films 15 on both sides of the frame body 14 and the inner wall of the placement groove 200. Subsequently, clamp and fix both ends of the frame body 14 through the clamping mechanism 21, and operate the driving component 4 to drive the fixed plate 20 to rotate from the horizontal state to the vertical state in the empty groove 110. At the same time, the swing arms 30 on both sides of the operating table 11 are driven by the driving component 4 to rotate from the horizontal state to the vertical state and are respectively located on both sides of the fixed plate 20.

[0047] Make the high-pressure nozzle 32 work to blow out high-pressure gas, causing the protective film 15 to vibrate, and a separation is generated between the top of the protective film 15 and the frame body 14. At this time, the bottom of the scraper 33 is aligned with the gap between the protective film 15 and the frame body 14. Subsequently, move the support frame 31 downward along the swing arm 30, thereby driving the high-pressure nozzle 32 and the scraper 33 to move downward, and scrape off the protective film 15 through the scraper 33. It can remove the film from the flexible lead frame, prevent the frame body 14 from deforming, and will not cause wear to the frame body 14. The film removal success rate is stable and the quality is high.

[0048] As Figures 1 to 12 shown:

[0049] The blow-off film removal assembly 3 further includes a pair of U-shaped sliders 330, two groups of first tension springs 34 and a pair of first hydraulic rods 35. The two U-shaped sliders 330 are respectively fixedly connected to both ends of the high-pressure nozzle 32. An arc-shaped groove 310 is provided at one end of the support frame 31, and the U-shaped slider 330 passes through the arc-shaped groove 310 and is slidably connected thereto. The two groups of first tension springs 34 are respectively located at both ends of the high-pressure nozzle 32. One end of the first tension spring 34 is fixedly connected to the top of the support frame 31, and the other end of the first tension spring 34 is fixedly connected to the top of the high-pressure nozzle 32. The top of the first hydraulic rod 35 is fixedly connected to the top wall of the swing arm 30, and the bottom of the telescopic end of the first hydraulic rod 35 abuts against the side of the high-pressure nozzle 32 away from the frame body 14.

[0050] The blow-off film removal assembly 3 further includes a pair of extension rods 36 and a plurality of second tension springs 37. One end of the top of the extension rod 36 passes through the side wall of the swing arm 30 and is slidably connected thereto. One end of the support frame 31 passes through the side wall of the extension rod 36 and is slidably connected thereto. One end of the second tension spring 37 is fixedly connected to the top wall of the swing arm 30, and the other end of the second tension spring 37 is fixedly connected to the top of the support frame 31.

[0051] The number of the blow-off film removal assemblies 3 is a pair and they are symmetrically distributed on both sides of the operating table 11. The number of each group of first tension springs 34 is a pair and they are respectively located on both sides of the high-pressure nozzle 32.

[0052] The film blowing and peeling assembly 3 further includes a rotating shaft 38 and a first gear 39. The rotating shaft 38 is fixedly connected to the bottom of the swing arm 30. A plurality of long slots 111 are provided at the top of the operating table 11. The rotating shaft 38 is rotatably connected to the inner wall of the long slot 111. The first gear 39 is coaxially connected to the periphery of the rotating shaft 38.

[0053] In the first stage of blowing air to peel the film when the high-pressure nozzle 32 operates, the high-pressure nozzle 32 is in a horizontal state. The air outlet of the high-pressure nozzle 32 is aligned with the gap between the protective film 15 and the placement groove 200. And the two high-pressure nozzles 32 are symmetrically arranged on both sides of the fixing plate 20 to enable synchronous operation. At this time, the high-speed air flow blown out by the two high-pressure nozzles 32 flows in from the gap between the protective film 15 and the frame body 14. Thus, while squeezing the frame body 14 to keep it flat, the protective film 15 is separated from the frame body 14, and with the vibration of the protective film 15, the separation gradually expands.

[0054] In the second stage, the telescopic end of the first hydraulic rod 35 shortens upward, and the first tension spring 34 rebounds. Since the first springs are respectively located on both sides of the high-pressure nozzle 32, the high-pressure nozzle 32 and the U-shaped slider 330 can rotate upward along the arc-shaped groove 310 without getting stuck. And during the rotation, the air outlet of the high-pressure nozzle 32 is always aligned with the gap between the protective film 15 and the placement groove 200. At this time, the air outlet of the high-pressure nozzle 32 is inclined downward, and the protective film 15 and the frame body 14 are further separated under the blowing of the high-speed air flow.

[0055] In the third stage, the telescopic end of the first hydraulic rod 35 elongates downward to push the high-pressure nozzle 32 to rotate downward, and its air outlet is inclined upward. At the same time, as the first hydraulic rod 35 continues to elongate and squeezes the high-pressure nozzle 32 downward, the support frame 31 slides downward along the swing arm 30, and the scraper 33 moves downward and scrapes the protective film 15 off the frame body 14. At this time, the upward air flow can provide an upward thrust to the protective film 15 to keep it under a certain tension and prevent the protective film 15 from bending and causing the film peeling to fail.

[0056] During the downward movement of the support frame 31, the second tension spring 37 is stretched. The support frame 31 first slides down along the extension rod 36, and then the extension rod 36 slides down along the swing arm 30 driven by the support frame 31, thereby extending the downward movement distance of the support frame 31 and enabling complete peeling of the protective film 15. The bottom of the scraper 33 is a conical structure, and the side away from the frame body 14 is an arc-shaped structure, which can further push the protective film 15 and the frame body 14 away from each other during the movement. The bottom of the scraper 33 can also apply a lubricant to prevent adhesion to the protective film 15.

[0057] As Figures 1 to 12 shown:

[0058] The clamping mechanism 21 includes a pressure roller 210, a bracket 211, a rotating seat 212 and a pair of torsion springs 213. The bottom of the pressure roller 210 is in contact with the top edge of the frame body 14. One end of the bracket 211 is rotatably connected to the outer periphery of the pressure roller 210, and the other end of the bracket 211 is rotatably connected to the inner wall of the rotating seat 212. The torsion spring 213 is sleeved on the outer periphery of the bracket 211, one end of the torsion spring 213 is fixedly connected to the bracket 211, and the other end of the torsion spring 213 is fixedly connected to the rotating seat 212. The rotating seat 212 is slidably installed on the fixed plate 20.

[0059] The clamping mechanism 21 also includes a track 214, a roller 215 and a second hydraulic rod 216. The bottom of the track 214 is fixedly connected to the top of the fixed plate 20, the roller 215 is slidably connected to the outer periphery of the bottom of the track 214, the roller 215 is rotatably connected to the inner wall of the rotating seat 212, one end of the second hydraulic rod 216 is fixedly connected to one end of the track 214, and the telescopic end of the second hydraulic rod 216 is fixedly connected to the rotating seat 212.

[0060] After the frame body 14 is moved into the placement groove 200, the two clamping structures work simultaneously, the telescopic end of the second hydraulic rod 216 extends, pushing the rotating seat 212 to move along the track 214, and the roller 215 rolls on the top of the track 214 to keep the rotating seat 212 stable in translation. At the same time, the rotating seat 212 pushes the bracket 211 to move, and the outer periphery of the pressure roller 210 and the outer bracket 211 rotates and rolls from the top of the fixed plate 20 to the top of the frame body 14 and contacts with its edge. During this process, the torsion spring 213 is always in a torsion state, and its rebound force pushes the bracket 211 to maintain a downward rotation trend, so that the pressure roller 210 applies a certain pressure to the frame body 14, thereby cooperating with the fixed plate 20 to clamp and fix the frame body 14.

[0061] like Figures 1 to 12 As shown:

[0062] The fixed flip assembly 2 also includes a pair of round rods 22, one end of the round rods 22 is fixedly connected to the other end of the track 214, and the other end of the round rods 22 passes through the side wall of the operating table 11 and is rotatably connected thereto. The driving assembly 4 includes a motor 40, a slide plate 41, a pair of first racks 42, a second gear 43 and a second rack 44. The bottom of the motor 40 is fixedly connected to the top of the base 1, the output shaft of the motor 40 passes through the side wall of the operating table 11 and is coaxially connected to the round rods 22, the slide plate 41 passes through the side wall of the operating table 11 and is slidably connected thereto, the two first racks 42 are symmetrically arranged on both sides of the bottom of the slide plate 41 and are fixedly connected thereto, the first rack 42 and the first gear 39 are meshed with each other, the second gear 43 is coaxially connected to the periphery of the round rod 22, the second rack 44 is fixedly connected to one side of the top of the slide plate 41, and the second rack 44 and the second gear 43 are meshed with each other.

[0063] When the swing arm 30 is in a horizontal state, one end of it is located in the long slot 111 to prevent hindering the movement of the frame body 14. Power on the motor 40 to make it work. The output shaft of the motor drives the round rod 22 to rotate. The round rod 22 drives the fixed plate 20 to rotate 90 degrees on the top of the operating table 11. At the same time, the round rod 22 drives the first gear 39 to rotate. Through the meshing transmission between the first gear 39 and the first rack 42, the slide plate 41 slides vertically in the operating table 11 and drives the two first racks 42 to move. Through the meshing transmission between the second rack 44 and the first gear 39, the swing arm 30 is driven to rotate 90 degrees. And because the two second racks 44 are symmetrically arranged, the swing arms 30 on both sides of the fixed plate 20 rotate in opposite directions, so as to rotate from the horizontal state to the vertical state on both sides of the fixed plate 20 respectively.

[0064] As Figures 1 to 12 shown:

[0065] It also includes a collection box 12, a pair of fixed platforms 13 and a conveying component 5.
