Description

Technical Field

[0001] This utility model relates to the field of chip assembly equipment technology, specifically to an assembly equipment for an automatic loading and unloading fixture, chip, and carrier tape. Background Technology

[0002] In the semiconductor industry, chip packaging, testing (such as CP testing, FT testing), and subsequent SMT mounting processes often require the transfer, positioning, and fixing of a large number of individual chips (dies) or chip units for automated operations (such as wire bonding, test probe contact, visual inspection, laser marking, or final mounting).

[0003] In the above process, carrier tape is widely used as a standardized, high-density, and continuous carrier medium. Carrier tape is usually a strip-shaped component made of metal material by stamping. It has grooves or cavities that match the size of the chip and are regularly arranged on it to accommodate a single chip. Some carrier tapes can also be temporarily fixed and protected by a cover film.

[0004] A fixture is a precision fixing device designed according to specific process requirements (such as test interface, welding platform, positioning reference). It is used to accurately and stably position and fix the carrier tape and the chip it carries on a specific work station (such as test machine, welding station, AOI station) to ensure the accurate execution of subsequent process steps.

[0005] The typical operating procedure in the current industry is to first place the chip into the carrier tape, then manually or semi-automatically pick up the sorted individual chips one by one and place them into the designated grooves of the carrier tape, and finally load the carrier tape into the fixture.

[0006] However, the seemingly simple process of "chip into carrier tape" and "carrier tape into fixture" faces many challenges and efficiency bottlenecks in actual large-scale production. When placing chips manually or in simple automation, the speed of placing chips into tiny carrier tape grooves is slow, especially for ultra-small chips, which is extremely difficult to operate and prone to fatigue. Furthermore, it is difficult to guarantee accuracy and consistency.

[0007] The existing technology's separate or inefficient integration of "chip into carrier tape" and "carrier tape into fixture" operation modes has significant shortcomings in terms of efficiency, accuracy, consistency and automation. Especially under the industry trend of continuously shrinking chip size, increasing packaging density and increasingly stringent testing accuracy requirements, how to achieve the rapid, accurate and reliable positioning and fixing of the carrier tape carrying the chip in the fixture, and the high-precision and high-speed placement of the chip in the carrier tape, so as to control the cumulative positional error of the chip relative to the fixture reference within the process requirements, is a key technical problem that urgently needs to be solved.

[0008] Therefore, it is necessary to improve and optimize the structure of the assembly equipment for jigs, chips and carrier tapes. Utility Model Content

The jig feeding assembly 3 is used to clamp the jig body 251 placed in the jig loading and unloading assembly 2 and place it on the jig transfer assembly 4.

[0065] The end of the workbench 1 away from the fixture loading and unloading assembly 2 is also connected to a carrier belt conveying assembly 5 for loading the carrier belt. The side of the carrier belt conveying assembly 5 near the fixture transfer assembly 4 is also provided on the workbench 1 with a carrier belt transfer assembly 6 for transferring the carrier belt.

[0066] The jig transfer assembly 4 is also fixedly equipped with a single-sided carrier tape clamping assembly 7, and the worktable 1 is also equipped with a chip placement assembly 8 for clamping chips and loading chips. The other side of the chip placement assembly 8 is also equipped with a finished product transfer assembly 9.

[0067] Specifically, the fixture loading and unloading assembly 2 includes a fixture loading assembly 21 set below the workbench 1 for feeding materials. The fixture loading assembly 21 includes two sets of feeding and discharging conveyor belts 211 set horizontally inside the fixture loading assembly 21, and a material conveying conveyor belt 212 set horizontally inside the fixture loading assembly 21.

[0068] The material conveyor belt 212 is laid in the direction of conveying materials towards the inside of the workbench 1. The material conveyor belt 212 and the infeed / outfeed conveyor belt 211 are set perpendicular to each other on the horizontal plane.

[0069] The fixture loading and unloading assembly 2 also includes a fixture lifting assembly 24 vertically arranged on one side of the fixture loading assembly 21. The side of the fixture lifting assembly 24 is also slidably provided with a lifting frame 23 whose height can be adjusted. A fixture support plate 25 is placed on the lifting frame 23. Several fixture bodies 251 are evenly arranged on the upper surface of the fixture support plate 25.

[0070] The jig lifting assembly 24 has several sets of guide rails 241 vertically arranged on its side. The jig lifting assembly 24 also has a traction transmission belt 242 connected end to end vertically arranged on its side. The traction transmission belt 242 is driven by a servo motor on the jig lifting assembly 24. The lifting frame 23 is connected to the traction transmission belt 242 and moves up and down along the guide rails 241 under the traction of the traction transmission belt 242 to adjust its height.

[0071] Two sets of material input and output conveyor belts 231 are horizontally arranged in the lifting frame 23, and the transmission direction of the material input and output conveyor belts 231 is consistent with the transmission direction of the material conveying conveyor belt 212.

[0072] Above the jig loading assembly 21, on the upper surface of the workbench 1, there is also a finished jig unloading assembly 22. The structure of the finished jig unloading assembly 22 is completely the same as that of the jig loading assembly 21. The finished jig unloading assembly 22 is used to lift the jig lifting plate 25 after the jig body 251 has been released, and to transfer the assembled finished product. In this embodiment, the jig loading and unloading assembly 2 can load the unprocessed jig body 251, and can also unload the processed and assembled jig body 251 with chips and carrier tape.

[0073] Specifically, the jig transfer assembly 4 includes a jig transfer disk 41 that is horizontally arranged above the worktable 1 and can rotate horizontally around its own central axis. The jig transfer disk 41 is driven to rotate by a servo motor arranged at the bottom of the jig transfer assembly 4. The jig transfer disk 41 rotates counterclockwise on the worktable 1 and rotates 90° in each cycle.

[0074] The jig transfer tray 41 has four stations on its outer edge. These stations are: a first station 411 on the first cycle for receiving the jig gripper a33 to place the jig body 251; a second station 412 on the second cycle for receiving the carrier tape to be placed on the jig body 251; a third station 413 on the third cycle for placing the chip on the jig body 251 with the carrier tape; and a fourth station 414 on the fourth cycle for conveying and transferring the finished product. In this embodiment, the jig transfer assembly 4 has four stations. However, in actual operation, different stations can be set according to the structure to be assembled, which further facilitates the chip processing and assembly operation.

[0075] Specifically, the jig feeding assembly 3 includes a jig gripping arm 31 fixed on the workbench 1, a telescopic rod a32 is vertically connected to the free end of the jig gripping arm 31, and a jig gripper a33 for gripping and releasing the jig body 251 is connected to the telescopic end of the lower end of the telescopic rod a32.

[0076] When the jig gripper a33 clamps the jig body 251, the jig gripping arm 31 swings 90° to rotate the jig body 251 horizontally by 90° and place it, so that the jig body 251 is adapted to the position of the first station 411. In this embodiment, the jig feeding component 3 can quickly clamp and feed the jig body 251 without the need for manual operation by the operator, which can further improve the processing efficiency.

[0077] Specifically, the carrier belt conveying assembly 5 includes a carrier belt feeding rack 51 set by a bracket, a carrier belt conveying wheel 52 for conveying the carrier belt is also provided at the end of the carrier belt feeding rack 51 away from the fixture transfer assembly 4, and a carrier belt cutting assembly 53 is also provided at the end of the carrier belt feeding rack 51 close to the fixture transfer assembly 4.

[0078] The carrier tape cutting assembly 53 includes a carrier tape cutting blade 531 vertically arranged above the carrier tape for cutting the carrier tape. A carrier tape cutting cylinder 532 is also arranged above the carrier tape cutting blade 531. The output end of the carrier tape cutting cylinder 532 is connected to the carrier tape cutting assembly 53 and adjusts the height of the carrier tape cutting blade 531. In this embodiment, the carrier tape conveying technology in the area of ​​the carrier tape conveying wheel 52 at the rear end of the carrier tape conveying assembly 5 adopts existing technology, so it will not be described in detail in this technical solution.

[0079] Specifically, the carrier tape transfer assembly 6 includes a carrier tape transfer arm 61 fixed on the workbench 1, a telescopic rod b62 vertically connected to the free end of the carrier tape transfer arm 61, and a carrier tape gripper a63 for gripping and releasing the cut carrier tape connected to the telescopic end of the lower end of the telescopic rod b62.

[0080] When the carrier tape gripper a63 clamps the carrier tape, the carrier tape transfer arm 61 swings 90° to rotate the carrier tape horizontally by 90° and place it, thereby making the carrier tape and the fixture body 251 fit together. In this embodiment, the carrier tape transfer component 6 can quickly transfer and install the carrier tape, effectively improving processing efficiency and accuracy.

[0081] Specifically, the single-sided carrier tape clamping assembly 7 is directly fixed above the jig transfer assembly 4. A first X-axis module 71 is horizontally arranged on the single-sided carrier tape clamping assembly 7. A first Z-axis module 72 is vertically arranged and slidably arranged on the first X-axis module 71. A first Y-axis module 73 is horizontally arranged and slidably arranged on the first Z-axis module 72. A mounting base 74 is horizontally arranged and slidably arranged on the first Y-axis module 73.

[0082] The bottom of the mounting base 74 is provided with a swingable single-sided carrier tape suction plate 741. The single-sided carrier tape suction plate 741 is connected to an external air pump through a pipe. The bottom of the single-sided carrier tape suction plate 741 can be attached to the single-sided carrier tape and suck up the single-sided carrier tape through vacuum.

[0083] An angle adjustment motor 742 is also provided above the single-sided carrier tape suction tray 741 on the mounting base 74. A transmission belt a743 for transmission is sleeved on one end of the single-sided carrier tape suction tray 741 and the output shaft of the angle adjustment motor 742. When the angle adjustment motor 742 runs, it drives the transmission belt a743 to drive the single-sided carrier tape suction tray 741 to deflect. In this embodiment, the single-sided carrier tape clamping component 7 can clamp and remove the edge carrier tape in the carrier tape, giving the chip more space and making it easier to place the chip on the fixture body 251.

[0084] Specifically, the chip placement assembly 8 includes a chip placement arm 81 fixed on the worktable 1, a telescopic rod c82 vertically connected to the free end of the chip placement arm 81, and a chip clamping gripper 83 for gripping the chip connected to the telescopic end of the lower end of the telescopic rod c82.

[0085] After the chip clamping gripper 83 picks up the chip from the externally set chip loading equipment, it is transferred to the third station 413 above the chip placement arm 81. After the single-sided carrier tape is picked up by the single-sided carrier tape suction tray 741, the chip is placed in the fixture body 251 with the other single-sided carrier tape.

[0086] After the chip is placed, the single-sided carrier tape suction tray 741 runs in reverse and puts the suctioned single-sided carrier tape back into the fixture body 251. In this embodiment, the chip clamping claw 83 on the chip placement component 8 can simultaneously clamp and place a whole row of chips, effectively improving work efficiency and facilitating the improvement of processing accuracy.

[0087] Specifically, the finished product transfer assembly 9 includes a second X-axis module 91, which can be fixedly mounted on the ceiling via a connecting frame. The bottom end of the second X-axis module 91 is horizontally slidably fitted with a displaceable second Y-axis module 92. The bottom end of the second Y-axis module 92 is horizontally slidably fitted with a vertically mounted second Z-axis module 93. The second Z-axis module 93 is vertically slidably fitted with a height-adjustable finished product placement gripper 94.

[0088] The finished product placement gripper 94 is used to grip and transfer the fixture body 251, which is transferred to the fourth station 414 to form a finished product.

[0089] After the finished product placement gripper 94 grips the finished product fixture body 251, it is transferred by the second Z-axis module 93, the second Y-axis module 92 and the second X-axis module 91 to place the finished product on the fixture support plate 25 on the finished product fixture unloading assembly 22. In this embodiment, the finished product is transferred by the finished product transfer assembly 9, which can transfer the finished product from the equipment without manual intervention and stack it on the fixture support plate 25.

[0090] Specifically, high-resolution vision cameras can be installed above the four workstations of the fixture transfer assembly 4 to correct the positions of the fixture body 251, carrier tape, and chip in real time to compensate for manufacturing tolerances. In this embodiment, the high-resolution vision system can further reduce the error when placing the chip and carrier tape and further improve the accuracy.

[0091] The working principle and usage process of this utility model: In the process of using this technical solution, the fixture body 251 is evenly placed on the fixture lifting plate 25 and transferred to the fixture loading assembly 21. When the infeed and outfeed conveyor belt 211 in the fixture loading assembly 21 runs, it transports the fixture lifting plate 25 to the top of the fixture loading assembly 21. During this process, the lifting frame 23 is driven by the traction transmission belt 242 to adjust its height to the same height as the fixture loading assembly 21.

[0092] When the material conveyor belt 212 is running, it transfers the jig lifting plate 25 to the lifting frame 23. When the material input / output conveyor belt 231 in the lifting frame 23 is running, it transfers the jig lifting plate 25 to the top of the lifting frame 23. Then, the traction transmission belt 242 drives the lifting frame 23 to be lifted, so that the height of the lifting frame 23 is raised to the same height as the finished jig unloading assembly 22.

[0093] At this time, the jig feeding component 3 operates by using jig gripper a33 to grip the jig body 251 on the jig lifting plate 25. After the jig gripper a33 grips the jig body 251, the jig gripping arm 31 and the telescopic rod a32 transfer the jig body 251 to the first station 411 for release. After the jig body 251 is placed on the first station 411, the jig transfer disk 41 rotates one cycle, transferring the first station 411 to the second station 412.

[0094] During this process, the carrier belt in the carrier belt conveyor assembly 5 is also transported synchronously. When the carrier belt conveyor wheel 52 rotates, it causes the carrier belt to move. When the carrier belt is transported to the side of the carrier belt loading rack 51 near the fixture transfer assembly 4, the carrier belt cutting cylinder 532 inside the carrier belt cutting assembly 53 operates and pushes its telescopic end to operate, so that the bottom end of the telescopic end pushes the carrier belt cutting knife 531 to sink, thereby causing the bottom end of the carrier belt cutting knife 531 to cut the carrier belt.

[0095] After being cut, the carrier tape is gripped and transferred by the carrier tape transfer assembly 6. After the carrier tape gripper a63 grips the carrier tape, it is transferred to the second station 412 by the carrier tape transfer arm 61 and the telescopic rod b62. The carrier tape is then placed on the fixture body 251 and released. After that, the fixture transfer plate 41 continues to rotate for one cycle, transferring the second station 412 to the third station 413.

[0096] When the jig body 251 with the carrier tape is at the third station 413, half of the carrier tape on the jig body 251 is first removed by the single-sided carrier tape clamping assembly 7. The mounting base 74 is adjusted in position by the first X-axis module 71, the first Z-axis module 72 and the first Y-axis module 73 so that the single-sided carrier tape suction plate 741 corresponds to the position of the single-sided carrier tape on the jig body 251.

[0097] Then, the angle adjustment motor 742 drives the transmission belt a743 to rotate the single-sided carrier tape suction plate 741, so that the bottom surface of the single-sided carrier tape suction plate 741 contacts the single-sided carrier tape.

[0098] Then, the single-sided carrier tape suction tray 741 vacuum-suctions the single-sided carrier tape through an external vacuum device. After vacuum suction, the single-sided carrier tape suction tray 741 moves away from the fixture body 251 by the angle adjustment motor 742. Then, the position is adjusted by the first X-axis module 71, the first Z-axis module 72 and the first Y-axis module 73, so that the single-sided carrier tape suction tray 741 moves away from the third station 413 station area, leaving a certain working space for the chip placement component 8.

[0099] On one side of the workbench 1, there is also a chip loading device. When the chip is transported to the side of the chip placement component 8 by the chip loading device, the chip placement component 8 operates and uses the chip clamping jaws 83 to clamp the chip on the chip loading device. Then, the chip is transferred to the third station 413 by the chip placement arm 81 and the telescopic rod c82. The chip is placed on the fixture body 251, which has been stripped of the single-sided carrier tape, by the chip clamping jaws 83. After placing the chip, the chip placement component 8 immediately moves away from the third station 413 and returns to the position of clamping the chip to clamp the chip on the chip loading device.

[0100] During this process, the single-sided carrier tape suction tray 741 with a single-sided carrier tape will adjust its position through the first X-axis module 71, the first Z-axis module 72 and the first Y-axis module 73, and place the stripped single-sided carrier tape on the fixture body 251 where the chip has been placed. The chip is fixed in the fixture body 251 by the two side carrier tapes, and at this time, the assembled finished product is formed.

[0101] Then the jig transfer plate 41 continues to rotate for one cycle, transferring the third station 413 to the fourth station 414. During this process, the finished product transfer component 9 operates, and the finished product placement gripper 94 can transfer the finished product to the fourth station 414 through the second X-axis module 91, the second Y-axis module 92 and the second Z-axis module 93. The finished product is gripped and transferred by the finished product placement gripper 94, and the finished product is transferred to the top of the finished product jig unloading component 22.

[0102] A set of jig lifting plates 25 are also placed on the lifting frame 23 to lift the finished jig body 251. After the number of finished jig bodies 251 on the jig lifting plates 25 reaches the standard, the finished products are transported out by the infeed and outfeed conveyor belt 211 in the finished jig unloading assembly 22.

[0103] In this technical solution, after the fixture body 251 on the fixture lifting plate 25 held above the lifting frame 23 is released, the material input / output conveyor belt 231 in the lifting frame 23 will run to horizontally transfer the fixture lifting plate 25 above it to the top of the finished fixture unloading assembly 22. The material conveying conveyor belt 212 set in the finished fixture unloading assembly 22 will run to transfer the fixture lifting plate 25 to the top of the finished fixture unloading assembly 22.

[0104] The above description is only a preferred embodiment of the present utility model and is not intended to further limit the present utility model. All equivalent changes made based on the description and drawings of the present utility model are within the protection scope of the present utility model.
