Description

Technical Field

[0001] The present invention relates to the technical field of integrated circuit packaging equipment, and particularly relates to a wafer feeding mechanism for integrated circuit packaging production. Background Art

[0002] In the rapidly developing integrated circuit industry today, integrated circuit packaging, as a key link in the entire production process, its production efficiency and product quality directly affect the performance and reliability of electronic products. The integrated circuit packaging production process involves delicate operations on a large number of tiny wafers, and the precise feeding of wafers is the basis for ensuring packaging quality and efficiency.

[0003] Traditional wafer feeding mechanisms for integrated circuit packaging production have exposed many problems in practical applications. In terms of wafer transportation, the traditional mechanism is particularly insufficient in terms of universality in dealing with wafers of different size specifications. Once wafers of different sizes need to be processed, it often takes a lot of time and manpower to replace the entire feeding device or perform complex re-adjustments, which undoubtedly increases production costs and also limits the flexibility and efficiency of production. In addition, when stacking and transporting wafers, the traditional feeding mechanism cannot effectively separate the wafers. It often occurs that multiple wafers enter the processing area simultaneously, that is, wafers are transported overlapping, which not only interferes with the normal processing flow but may also cause equipment failures, further reducing production efficiency and product quality.

[0004] Precisely based on the above series of problems existing in the traditional wafer feeding mechanism for integrated circuit packaging production, the present invention is committed to developing a brand-new wafer feeding mechanism to enhance the adaptability of the equipment to different wafer sizes, improve product quality, and provide a more reliable and efficient solution for integrated circuit packaging production. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve the technical problems is: a sheet feeding mechanism for integrated circuit packaging production, comprising: a conveyor, the outer wall of the conveyor is fixedly connected to a mounting frame, the outer wall of the mounting frame is fixedly connected to a driving motor, a pulley group is arranged outside the mounting frame, a toggle device is arranged at the center of the mounting frame, the toggle device is used to control the distance of the sheets on the conveyor, the outer wall of the conveyor is fixedly connected to a separation device, the separation device is used to separate the sheets on the conveyor; the toggle device comprises a limit frame, the inner wall of the limit frame is slidably connected to a slider, the outer wall of the slider is fixedly connected to a distance sensor, the outer wall of the slider is rotatably connected to a drag rod, the inner wall of the slider is fixedly connected to a telescopic rod, and the end of the drag rod away from the slider is rotatably connected to a distance adjusting rod; the separation device comprises a frame, the outer wall of the frame is rotatably connected to a fixed frame, the outer wall of the fixed frame is fixedly connected to a baffle, the end of the fixed frame away from the baffle is fixedly connected to a limited block, and a linkage component is arranged outside the frame.

[0006] The present invention is further configured such that the outer wall of the limit frame is fixedly connected to the outer wall of the mounting frame, the bottom end of the telescopic rod is fixedly connected with a stopper, and the outer wall of the stopper is slidably connected to the outer wall of the conveyor. The slider reciprocates on the limit frame, and drives the stopper to move through the connection of the telescopic rod, so that the sheet also moves. With the rotation of the rotating rod, when the slider reaches the farthest distance of movement, it moves back. At this time, the distance sensor senses the change in the moving distance, and drives the telescopic rod to retract upward, so that the stopper no longer blocks the sheet, and the sheet can continue to move, and the telescopic rod drives the stopper to continue to move downward, so as to block the next sheet. The model of the drive-away sensor is an infrared photoelectric sensor of EE-SX670.

[0007] The present invention is further configured such that the outer wall of the pitch-adjusting rod is rotatably connected to a pull rod, the bottom end of the pull rod is provided with a rotating rod, the outer wall of the rotating rod is fixedly connected to a rotating handle, and the inner wall of the rotating rod is threadedly connected to a threaded rod. The driving motor drives the rotating rod to rotate on the mounting frame, and the rotating rod drives the fixedly connected rotating handle to rotate, and through the connection of the pull rod and the restriction of the threaded rod, the pitch-adjusting rod is driven to rotate, thereby driving the end connected to the drag rod to make a circular motion, thereby dragging the slider to reciprocate on the limit frame.

[0008] The present invention is further configured such that the end of the rotating handle away from the rotating rod is rotatably connected to the pull rod, the top end of the threaded rod is rotatably connected to the inner wall of the pitch-adjusting rod, the outer wall of the rotating rod is rotatably connected to the inner wall of the mounting frame, and the outer wall of the rotating rod is fixedly connected to the output end of the driving motor. Through the connection between the threaded rod and the rotating rod, the threaded rod drives the pitch-adjusting rod to move, thereby adjusting the distance between the pitch-adjusting rod and the rotating rod, changing the circumferential radius of the circular motion of the dragging rod, and changing the moving distance of the slider on the mounting frame, thereby adjusting the limiting distance of the sheet.

[0009] The present invention is further configured such that the inner wall of the mounting frame is fixedly connected to a driving rod, the outer wall of the driving rod is slidably connected to a limiting plate, the inner wall of the limiting plate is rotatably connected to a guide wheel, and the outer wall of the limiting plate is slidably connected to the outer wall of the conveyor.

[0010] The present invention is further configured such that the outer wall of the frame is fixedly connected to the outer wall of the conveyor, the inner wall of the limit block is slidably connected to a slide plate, the bottom end of the slide plate is fixedly connected to a rubber sleeve, the inner wall of the limit block is fixedly connected to a push spring, and the bottom end of the push spring is fixedly connected to the outer wall of the slide plate. Through the connection of the pulley group, the connecting rod rotates and drives the half-toothed gear to rotate, and when it is meshed with the rotating gear, it drives the linkage rod to rotate, so that the linkage rod drives the fixed frame to rotate on the frame, so that the blocking piece is lifted and no longer blocks the material piece, so that it can enter the toggle device.

[0011] The present invention is further configured such that the linkage assembly includes a linkage rod, the outer wall of the linkage rod is fixedly connected to a rotating gear, the outer wall of the rotating gear is fixedly connected to a torsion spring, a connecting rod is arranged outside the linkage rod, and the outer wall of the connecting rod is fixedly connected to a half-toothed gear. When the blocking piece moves upward, the limit block moves downward, and through the push of the push spring, the slide plate moves downward to block the material piece.

[0012] The present invention is further configured such that the outer wall of the linkage rod is rotatably connected to the inner wall of the frame, and penetrates the frame and is fixedly connected to the outer wall of the fixed frame, the outer wall of the connecting rod is rotatably connected to the inner wall of the frame, and the connecting rod is transmission-connected to the rotating rod through a pulley set. When the half-toothed gear is not meshed with the rotating gear, under the action of the torsion spring, the linkage rod rotates and resets, so that the slide plate moves upward without blocking, and the blocking piece moves downward to block, thereby separating the stacked sheets.

[0013] The present invention is further configured such that the rotating gear is meshed with the half-tooth gear, and one end of the torsion spring away from the rotating gear is fixedly connected to the outer wall of the frame.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The present invention ensures the continuity of the material supply by arranging a conveyor to stably transport the material from the storage position to the processing position. When the material reaches the shifting device, the block works in conjunction with a series of mechanical transmission components to achieve the movement and positioning of the material. The driving motor drives the rotating rod to rotate, and the rotating rod drives the rotating handle, the pull rod, the distance adjustment rod and other components to move, thereby controlling the connecting end of the drag rod to make a circular motion, further driving the slider to move back and forth on the limit frame, and finally achieving the precise shifting of the material by the block. This design enables the material to move accurately according to the preset path and distance, improves the efficiency and accuracy of material transportation, reduces manual intervention, and reduces the probability of error.

[0016] 2. The present invention can adjust the distance between the distance-adjusting rod and the rotating rod by setting a toggle device and rotating the threaded rod, thereby changing the radius of the circular motion of the dragging rod, and finally adjusting the moving distance of the slider on the mounting frame, which means that the limiting distance of the sheet can be flexibly adjusted. This function enables the mechanism to adapt to sheets of different sizes and specifications, greatly enhancing the versatility and applicability of the device.

[0017] 3. The present invention provides reliable guarantee for the stable conveying of the sheet by setting the limit plate and the guide wheel. The limit plate can slide flexibly on the driving rod according to the size of the sheet until the guide wheel contacts the sheet, thereby limiting the position of the moving sheet, effectively preventing the sheet from tilting during the conveying process, ensuring that the sheet is always in the correct conveying position, and improving the processing quality of the product.

[0018] 4. The present invention provides a separation device, which can accurately separate the sheets one by one during the stacking and conveying of the sheets. When a sheet is blocked in the shifting device, the next sheet is blocked by the blocking sheet and cannot move. When the sheet in the shifting device is no longer blocked, a series of gears and linkage rods are driven by the pulley group to move, so that the blocking sheet is lifted and lowered, and the slide plate moves up and down accordingly, so as to accurately separate the stacked sheets, ensure that only one sheet enters the shifting device at a time, and avoid overlapping conveying of the sheets.

[0038] Working principle:

[0039] When in use, the sheet is placed on the conveyor 1 for conveying, which is responsible for conveying the sheet from the storage position to the processing position. When the sheet is conveyed to the toggle device 3, the sheet is blocked by the block 34. At this time, the driving motor 6 drives the rotating rod 37 to rotate on the mounting frame 2, and the rotating rod 37 drives the fixedly connected rotating handle 311 to rotate, and through the connection of the pull rod 310 and the restriction of the threaded rod 39, the distance adjustment rod 38 is driven to rotate, thereby driving the end connected to the drag rod 36 to make a circular motion, thereby dragging the slider 32 to reciprocate on the limit frame 31, and driving the block 34 to move through the connection of the telescopic rod 33, so that the sheet will also move. With the rotation of the rotating rod 37, when the slider 32 reaches the farthest distance of movement, it will move back. At this time, the change of the moving distance is sensed by the distance sensor 35, and the telescopic rod 33 is driven to retract upward, so that the block 34 no longer blocks the sheet, and the sheet can continue to move, and the telescopic rod 33 drives the block 34 to continue to move downward, so as to block the next sheet.

[0040] The threaded rod 39 is rotated, and through the connection between the threaded rod 39 and the rotating rod 37, the threaded rod 39 drives the distance-adjusting rod 38 to move, thereby adjusting the distance between the distance-adjusting rod 38 and the rotating rod 37, changing the circumferential radius of the circular motion of the dragging rod 36, and changing the moving distance of the slider 32 on the mounting frame 2, thereby adjusting the limiting distance of the sheet. The limiting plate 7 slides on the driving rod 8 according to the size of the sheet until the guide wheel 9 contacts the sheet, thereby limiting the position of the moving sheet to prevent tilting.

[0041] When one sheet is blocked in the toggle device 3, the next sheet is blocked by the blocking piece 43 and cannot move through the provided separation device 4. When it is not blocked in the toggle device 3, the connecting rod 455 is rotated through the connection of the pulley group 5 and drives the half-tooth gear 454 to rotate. When it meshes with the rotating gear 452, it drives the linkage rod 453 to rotate, so that the linkage rod 453 drives the fixed frame 42 to rotate on the frame 41, so that the blocking piece 43 is lifted and no longer blocks the sheet, so that it can enter the toggle device 3. In this process, the limit block 44 moves downward and, through the push of the push spring 46, the slide plate 47 moves downward to block the sheet. When the half-tooth gear 454 is not meshed with the rotating gear 452, under the action of the torsion spring 451, the linkage rod 453 rotates and resets, so that the slide plate 47 moves upward and no longer blocks it, while the blocking piece 43 moves downward to block it, thereby separating the stacked sheets.
