Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of feeding and discharging equipment, and particularly relates to feeding and discharging equipment for high-density integrated circuit lead frames. BACKGROUND

[0002] In the production and manufacturing process of high-density integrated circuits, lead frames, as the key carriers for connecting chips and external circuits, have their processing precision and production efficiency directly affecting the quality of the entire integrated circuit. The feeding and discharging link of the lead frame, as an important link in the production process, has its automation degree and adaptability directly related to the continuous and stable operation of the production line. Among them, the turnover feeding mechanism in the feeding and discharging equipment undertakes the important task of turning over the lead frame in a lying posture to a standing posture and accurately conveying it to the subsequent processing station (such as a steel belt conveying mechanism).

[0003] In the prior art, various automatic devices have appeared for the turnover feeding of lead frames, such as the turnover material transfer device for high-density integrated circuit lead frame electroplating production lines with the patent number CN202420585036.X, which discloses a technical solution for turning over and feeding the lead frame by a mechanical hand. The basic working principle is to use a conveying module to convey the lead frame to a specified position, then clamp the lead frame by a clamping jaw and a supporting structure, and then turn over the clamping jaw by a turnover driving mechanism to realize the conversion from a lying posture to a standing posture, and finally feed the lead frame to the steel belt of the steel belt conveying mechanism.

[0004] However, the existing turnover feeding mechanism has obvious limitations in actual application: the installation position of the clamping jaw is usually fixed, and its lateral spacing and relative position cannot be adjusted according to the size of the lead frame. Since the specifications of high-density integrated circuit lead frames are diverse, the length and width of different models of products differ, and when different sizes of lead frames need to be replaced, the fixed-position clamping jaw is difficult to adapt to the grasping needs of new-specification products, and if it is forcibly used, it may cause problems such as clamping position deviation. Therefore, the present application provides a feeding and discharging equipment for high-density integrated circuit lead frames to solve the above technical problems. SUMMARY

[0005] The present application aims to provide a feeding and discharging equipment for high-density integrated circuit lead frames to solve the technical problem that the turnover feeding mechanism in the existing feeding and discharging equipment cannot clamp different sizes of lead frames.

[0006] To achieve the above-mentioned purpose, the technical solution of the present application is as follows:

[0009] The application has the following beneficial effects: after a plurality of piles of lead frames are placed on the specified position of the lifting feeding mechanism, the lifting feeding mechanism is operated to lift the uppermost lead frame, the carrying assembly is operated to carry the lead frame to the initial end of the conveying module, and the conveying module is operated to horizontally convey the lead frame; the carrying assembly carries the lead frame every time, the lifting feeding mechanism lifts the lead frame by a distance every time, and the lead frame is intermittently lifted to facilitate the carrying assembly to take the lead frame from the pile; the material moving process of the lead frame is realized, and the subsequent feeding process of the lead frame is facilitated.

[0010] When the lead frame is conveyed to the terminal end of the conveying module, the lifting electric cylinder is operated first, the second support plate is controlled to move downwards, the bottom of the second support plate is in contact with the lead frame, then the rotating shaft is driven to rotate, the rotating shaft drives the clamping claws to rotate, the clamping claws are matched with the bottom of the second support plate to clamp the lead frame, the second support plate is controlled to reset upwards after clamping, the turnover module controls the lifting electric cylinder to turn over to drive the clamped lead frame to turn over upwards by 90 degrees, the lead frame is in an upright posture and is clamped by the steel belt conveying mechanism, and the lead frame is fed to the steel belt in a reciprocating manner, so that the automatic feeding is realized, and the feeding efficiency of the lead frame is improved.

[0011] In addition, when the position of the material clamping jaw needs to be adjusted, the control movable seat is moved laterally on the second support plate, thereby moving the material clamping jaw laterally, so that the position of the material clamping jaw is adjusted to adapt to lead frames of different sizes, and the adaptability of the turnover feeding mechanism is improved.

[0040] As shown in Figure 1 , the embodiment of the high-density integrated circuit lead frame feeding and discharging equipment comprises a support frame 1, which is provided with a feeding module 100 for feeding the lead frames one by one to the steel belt and a discharging module 200 for taking the lead frames on the steel belt one by one. The feeding module 100 and the discharging module 200 have the same structure and are oppositely arranged in terms of operation mode.

[0041] As shown in Figures 2-4As shown, the feeding module 100 comprises a material moving mechanism and a turnover feeding mechanism. The material moving mechanism comprises a support table 5, the support table 5 is provided with a conveying module 8 for horizontally conveying the lead frame, the support table 5 is shaped with a material taking port 7 beside the initial end of the conveying module 8, a lifting feeding mechanism is arranged below the support table 5 for lifting the stacked lead frame to the material taking port 7, and a carrying assembly 9 is arranged beside the conveying module 8 for carrying the lead frame placed in the material taking port 7 to the conveying module 8 piece by piece. After placing the multiple stacks of stacked lead frames at the specified position on the lifting feeding mechanism, the lifting feeding mechanism is operated to lift one stack of stacked lead frames upward to the material taking port 7, at this time, the carrying assembly 9 is operated to carry the uppermost lead frame to the initial end position of the conveying module 8, and then the conveying module 8 is operated to horizontally convey the lead frame, and after conveying to the end, the turnover feeding mechanism is convenient for taking out the lead frame for feeding; in addition, the lifting feeding mechanism lifts the stacked lead frame by a distance of one piece after the conveying module 8 carries one piece, and the lifting is intermittent, so that the carrying assembly 9 takes away the stacked lead frame piece by piece, realizes the material moving treatment of the lead frame, and is convenient for subsequent piece-by-piece feeding of the lead frame.

[0042] In order to enable the carrying assembly 9 to accurately carry the lead frame placed in the material taking port 7, the support table 5 is provided with a guide and limiting assembly 6 placed in the material taking port 7 and used for guiding and limiting the lead frame during lifting. During the lifting and feeding process of the lifting feeding mechanism for the stacked lead frame, the guide and limiting assembly 6 is used for guiding and limiting, so that the stacked lead frame can be accurately placed in the material taking port 7, the deviation and collapse during lifting are avoided, and the efficiency of material moving is improved.

[0043] The support table 5 is also provided with a material supporting assembly 10 placed beside the material taking port 7 and used for supporting the lead frame placed in the material taking port 7. When the stacked lead frame on the lifting feeding mechanism is about to be carried by the carrying assembly 9, the material supporting assembly 10 is operated so that the material supporting part thereof is below the remaining lead frame, after the lifting feeding mechanism is reset, the material supporting part of the material supporting assembly 10 supports the remaining lead frame, and the remaining lead frame can also be intermittently moved upward with a distance of the thickness of one lead frame, and through cooperation with the carrying assembly 9, the remaining lead frame is carried to the initial end position of the conveying module 8, and at the same time, the lifting feeding mechanism is ready to lift the next stack of stacked lead frames to the material taking port 7, realizing uninterrupted carrying and moving of the lead frame.

[0044] The support table 5 is provided with a conveying module 11 for conveying the lead frame, the tail end of the conveying module 11 is connected with the head end of the conveying module 8, and the head end of the conveying module 11 is connected with other feeding equipment (not shown in the figure). When the conveying module 8, the conveying module 11 and other feeding equipment are operated, the lead frame can also be conveyed to the designated position by another feeding mode, so that the material moving mechanism has diversified feeding modes, and the adaptability of the material moving mechanism is improved.

[0045] The turnover feeding mechanism includes a support frame 12 provided on the support table 5, a steel belt conveying mechanism 13 provided on the support frame 12 and used for conveying the lead frame in an upright posture, and a feeding manipulator 14 provided above the conveying module 8 and used for feeding the lead frame placed at the tail end of the conveying module 8 to the steel belt conveying mechanism 13 in a piece-by-piece turnover manner. The lead frames in a pile are carried to the head end of the conveying module 8, and the conveying module 8 is operated to convey the lead frames transversely. After the lead frames are conveyed to the designated position at the tail end, the lead frames are aligned with the feeding manipulator 14, and the feeding manipulator 14 is operated to feed the lead frames at the designated position to the steel belt of the steel belt conveying mechanism 13 in a turnover manner (from a flat posture to an upright posture). The steel belt conveying mechanism 13 horizontally conveys the long steel belt. The above feeding mode and the specific structure of the steel belt conveying mechanism 13 are prior art, and the specific structure is shown in the patent No. CN202310183635.9, a diaphragm separation feeding device of an integrated circuit lead frame brown oxidation electroplating equipment. The prior art diaphragm separation feeding device of the integrated circuit lead frame brown oxidation electroplating equipment discloses the turnover feeding of the lead frame and the horizontal conveying of the steel belt, which will not be described in detail here.

[0046] In addition, the working principle of the discharging module 200 is that the steel belt conveying mechanism 13 in the discharging module 200 is used for conveying the steel belt carrying a plurality of lead frames. After the lead frames are conveyed to align with the feeding manipulator 14, the feeding manipulator 14 is operated to take the lead frames on the steel belt one by one and place them at the tail end of the conveying module 8. The conveying module 8 is operated to convey the lead frames to align with the carrying assembly 9. The carrying assembly 9 is operated to carry the lead frames one by one to the material taking port 7. The discharging process of the discharging module 200 is opposite to the above-mentioned feeding process, which will not be described in detail here.

When the material receiving spring clip 3 is placed in each placing station, the transverse moving plate 22 is controlled to move transversely on the first support plate 21, that is, all the spring clip limiting frames 23 move transversely together, drive one group of spring clip limiting frames 23 to align with the lifting assembly 4, then operate the lifting assembly 4 to lift the lead frame frame in the corresponding material receiving spring clip 3 to a specified height, so as to lift the stacked lead frame frames to the material taking opening 7 for the carrying assembly 9 to carry. After the carrying is completed, the transverse moving plate 22 is controlled to move transversely by a specified distance again, so that the next material receiving spring clip 3 aligns with the lifting assembly 4, and the transverse moving plate 22 is controlled to move transversely so that different material receiving spring clips 3 align with the lifting assembly 4 in turn.

When the cartridge limiting frame 23 lifts the material cartridge 3 placed at the placing station to a specified height and aligns with the material supporting rod 411, first control the first movable seat 42 to move laterally on the base 41 towards the transverse plate 22, so that the two material supporting rods 411 are respectively inserted into different insertion grooves 34 from the frame opening 33, at this time, the two material supporting rods 411 are placed at the bottom of the stacked lead frame, then control the lifting seat 45 to move upwards, so that the stacked lead frame is lifted to a specified height by the two material supporting rods 411, so that the uppermost lead frame is placed at a specified carrying position, which is convenient for subsequent carrying treatment, the two material supporting rods 411 lift the stacked lead frame by one piece of distance each time, and the stacked lead frame is taken away piece by piece through intermittent lifting.

[0053] In addition, the lifting seat 45 is provided with an adjusting component which is used to control the left movable rod 49 and the right movable rod 410 to move towards or away from each other. The length direction of the lead frame placed in the placing chamber is parallel to the moving direction of the left movable rod 49 and the right movable rod 410; according to the length size of the lead frame, the distance between the left movable rod 49 and the right movable rod 410 can be controlled, so as to adjust the position of the two material supporting rods 411 and align with different insertion grooves 34, when the lead frame to be lifted is long, control the left movable rod 49 and the right movable rod 410 to move away from each other by a specified distance, otherwise, control them to move close to each other by a specified distance.

[0054] In order to control the first movable seat 42 to move laterally on the base 41 towards or away from the direction of the horizontal moving plate 22, a first screw rod 43 is arranged on the base 41 in parallel with the moving direction of the first movable seat 42, the first screw rod 43 is threadedly connected with the first movable seat 42, the base 41 is further provided with a first servo motor 44, the output shaft of the first servo motor 44 is connected with one end of the first screw rod 43 through a coupling. The first servo motor 44 is operated to drive the first screw rod 43 to rotate, and the first movable seat 42 can be controlled to move laterally under the thread cooperation between the first screw rod 43 and the first movable seat 42.

[0055] In order to control the lifting seat 45 to move up and down on the first movable seat 42, a second screw rod 46 is arranged on the first movable seat 42 in parallel with the moving direction of the lifting seat 45, the second screw rod 46 is threadedly connected with the lifting seat 45, the top of the first movable seat 42 is provided with a second servo motor 47, the output shaft of the second servo motor 47 is drivingly connected with the top end of the second screw rod 46 through a transmission member 48.

The transmission member 48 is a transmission structure composed of transmission gears and transmission toothed belts, which is not described here.

[0056] The adjusting member comprises a first sliding seat 412 arranged laterally in the lifting seat 45, the moving direction of the first sliding seat 412 is parallel with the moving direction of the first movable seat 42, the first sliding seat 412 is provided with a first adjusting block 413, the first adjusting block 413 is formed with left and right slide grooves 414 and 415 which are both arranged obliquely, the left and right slide grooves 414 and 415 are arranged in the shape of an "eight", the left and right movable rods 49 and 410 are both provided with first rollers 416, the first roller 416 on the left movable rod 49 is arranged in the left slide groove 414, and the first roller 416 on the right movable rod 410 is arranged in the right slide groove 415. When the first sliding seat 412 is controlled to move laterally in the lifting seat 45, the first adjusting block 413 moves laterally together, and the first rollers 416 slide in the corresponding slide grooves during the movement, so as to make the left and right movable rods 49 and 410 approach or move away from each other.

[0057] A third lead screw 417, whose length direction is consistent with the sliding direction of the first sliding seat 412, is rotatably provided on the lifting seat 45. The third lead screw 417 is threadedly connected to the first sliding seat 412. The lifting seat 45 is equipped with a third servo motor 418 for driving the rotation of the third lead screw 417. When the third servo motor 418 operates, it drives the third lead screw 417 to rotate, thereby controlling the lateral movement of the first sliding seat 412 through the threaded engagement between the third lead screw 417 and the first sliding seat 412.

[0058] like Figures 8-9 As shown, the guide and limiting assembly 6 includes a left limiting plate 61 and a right limiting plate 62 respectively placed on the left and right sides of the feeding port 7. The left limiting plate 61 and the right limiting plate 62 are used to guide and limit the two width sides of the lead frame placed at the feeding port 7. The left limiting plate 61 and the right limiting plate 62 are each provided with a front limiting plate 63 and a rear limiting plate 64 arranged in a front-to-back manner on their respective sides. The front limiting plate 63 and the rear limiting plate 64 are respectively placed on the front and rear sides of the feeding port 7 and are used to guide and limit the two length sides of the lead frame placed at the feeding port 7. During the process of lifting the piled lead frames in the receiving magazine 3 to the picking port 7, the lifting component 4 guides and limits the two width sides of the lead frames through the left limiting plate 61 and the right limiting plate 62, and guides and limits the two length sides of the lead frames through the front limiting plate 63 and the rear limiting plate 64. This combination ensures that the piled lead frames can be accurately lifted to the picking port 7, improving the accuracy of the subsequent material handling component 9 when picking up materials.

[0059] In addition, to accommodate lead frames of different sizes, the left limiting plate 61 and the right limiting plate 62 can be laterally slidably disposed on the support platform 5 in the direction of approaching or moving away from each other. The rear limiting plate 64 on the left limiting plate 61 and the rear limiting plate 64 on the right limiting plate 62 can both slide in the direction of approaching or moving away from the front limiting plate 63, thereby making the distance between the left limiting plate 61 and the right limiting plate 62 adjustable, and the distance between the front limiting plate 63 and the rear limiting plate 64 placed on the same side adjustable.

[0060] To achieve automatic spacing adjustment, a forward and reverse threaded rod 65 is rotatably mounted on the bottom of the support platform 5, with its length direction aligned with the sliding direction of the left limiting plate 61 (or right limiting plate 62). Different threaded portions on the forward and reverse threaded rod 65 are threadedly connected to the left limiting plate 61 and the right limiting plate 62, respectively. A first driving component 66 is also installed on the bottom of the support platform 5 to drive the forward and reverse threaded rod 65 to rotate. The first driving component 66 is existing technology and can be a transmission structure composed of a motor, transmission gears, and transmission belts, etc., which will not be described in detail here. The first driving component 66 drives the forward and reverse threaded rod 65 to rotate in both directions, thereby adjusting the spacing between the left limiting plate 61 and the right limiting plate 62 under the action of the threaded connection.

[0061] Secondly, the left limiting plate 61 and the right limiting plate 62 are both provided with a fixed frame 67 on the side away from each other, each fixed frame 67 is provided with a first control component 68, and the first control components 68 on both sides are respectively used to drive the corresponding rear limiting plate 64 to move horizontally. The first control component 68 on the left side drives the rear limiting plate 64 on the left side to move horizontally, and the first control component 68 on the right side drives the rear limiting plate 64 on the right side to move horizontally.
