Description

Technical Field

[0001] This invention relates to the field of chip processing technology, and more specifically to an integrated circuit chip manufacturing apparatus for navigation terminals. Background Technology

[0002] In the field of modern electronics, the performance and reliability of navigation terminals are highly dependent on the quality and manufacturing process of integrated circuit chips. Chip dicing, as a crucial step in integrated circuit chip manufacturing, directly impacts chip yield and production costs through its processing precision and efficiency. Currently, mainstream chip dicing equipment primarily uses mechanical or laser cutting methods to separate chip units on a wafer, forming individual chips. However, existing chip cutting equipment has the following shortcomings in practical use: Most of the equipment is designed to be compatible with chip cutting operations of a single size. When it is necessary to process chips of different sizes and specifications, it is often necessary to replace the special cutting equipment or adjust the complex mechanical structure. This not only increases the cost of equipment purchase and maintenance, but also significantly reduces production efficiency. Existing cutting equipment generally lacks an effective limiting mechanism for the width direction of the chip. During the cutting process, it is impossible to accurately position and fix chips of different widths, which can easily cause the chips to shift during the cutting process, thus affecting the cutting accuracy and even causing chip damage. This seriously restricts the yield and production efficiency of chip manufacturing. Summary of the Invention

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] The present invention will be further described below with reference to embodiments.

[0020] Example: Refer to Figures 1 to 5 An integrated circuit chip manufacturing apparatus for a navigation terminal, comprising: The support frame 1 includes a horizontally arranged processing table 11. Multiple support legs 12 are fixedly connected to the lower end of the processing table 11. An equipment slot 13 is opened at the upper end of the processing table 11. A conveying structure 14 is arranged in the equipment slot 13. The conveying structure 14 can adopt common conveying methods such as belt drive and chain drive to smoothly convey the chip to be cut from left to right.

[0021] The right end of the support frame 1 is fixedly connected to the feeding plate 5, and the feeding plate 5 is set with the left side higher than the right side. This design is to use gravity to allow the cut chip to slide smoothly along the feeding plate 5, which is convenient for collection, reduces manual operation costs, and improves production efficiency.

[0022] The limiting component 2 includes a mounting plate 21 fixedly connected to the lower end of the processing table 11. A mounting box 22 is fixedly connected to the lower end of the mounting plate 21. A driving bevel gear 23 is rotatably connected to the inner bottom wall of the mounting box 22. Two driven bevel gears 24, meshing with the driving bevel gear 23, are symmetrically rotatably connected to the inner walls of both sides of the mounting box 22. A limiting motor 25 driving the driving bevel gear 23 is fixedly installed at the lower end of the mounting box 22. A limiting threaded rod 26 passing through the side wall of the mounting box 22 is coaxially fixedly connected to the opposite ends of the two driven bevel gears 24. A threaded sleeve plate 27 is threaded onto the rod body of the limiting threaded rod 26. Multiple sliding rods 28 passing through the vertical plate 15 are fixedly connected to the opposite ends of the two threaded sleeve plates 27. A limiting plate 29 is fixedly connected to the other ends of the multiple sliding rods 28. When the limiting motor 25 is fixedly installed at the lower end of the mounting box 22... When the position motor 25 starts, it drives the active bevel gear 23 to rotate. The rotation of the active bevel gear 23 drives the two driven bevel gears 24 meshing with it to rotate synchronously. The opposite ends of the two driven bevel gears 24 are coaxially fixedly connected to a limiting threaded rod 26 that passes through the side wall of the mounting box 22. Due to the rotation of the driven bevel gears 24, the limiting threaded rod 26 will also rotate. The rod body of the limiting threaded rod 26 is threadedly sleeved with a threaded sleeve plate 27. When the limiting threaded rod 26 rotates, the threaded sleeve plate 27 will move axially on the limiting threaded rod 26. The opposite ends of the two threaded sleeve plates 27 are fixedly connected to multiple sliding rods 28 that pass through the vertical plate 15. These sliding rods 28 slide in the holes on the vertical plate 15, playing a guiding role and ensuring that the threaded sleeve plates 27 move smoothly, so that the distance between the two limiting plates 29 can be adjusted as needed.

[0023] Multiple rotating grooves 291 are provided at opposite ends of the two limiting plates 29, and an auxiliary wheel 292 is rotatably connected in each rotating groove 291. During chip transfer, the auxiliary wheel 292 contacts the chip, which can reduce the friction between the chip and the limiting plate 29 and prevent the chip surface from being scratched. On the other hand, the auxiliary wheel 292 can better adapt to the movement of the chip, further improve the limiting effect, ensure that the chip does not shift during transfer, and ensure the accuracy of subsequent cutting.

[0024] Specifically, the cutting assembly 3 has two vertical plates 15 symmetrically fixedly connected to the upper end of the processing table 11 about the equipment slot 13. The cutting assembly 3 includes a horizontal plate 31 fixedly connected to the upper end of the two vertical plates 15. An electric push rod 32 is fixedly installed at the lower end of the horizontal plate 31. A mounting base 33 is fixedly connected to the telescopic end of the electric push rod 32. A cutting blade 34 is fixedly installed at the lower end of the mounting base 33. When the electric push rod 32 is started, it can drive the mounting base 33 to move up and down. As the mounting base 33 descends, the cutting blade 34 will gradually approach the chip to realize the chip cutting operation. During the cutting process, the electric push rod 32 can precisely control the distance and speed of the cutting blade 34's descent to ensure the cutting accuracy and quality.

[0025] The length adjustment component 4 specifically includes a fixed plate 41 fixedly connected to the upper end of the mounting base 33. The right end of the fixed plate 41 is rotatably connected to an length adjustment threaded rod 42. The left end of the fixed plate 41 is fixedly installed with a length adjustment motor 43 for driving the length adjustment threaded rod 42 to rotate. The rod body of the length adjustment threaded rod 42 is threadedly sleeved with a threaded sleeve block 44. The mounting base 33 is also fixedly connected with a guide rod that passes through the threaded sleeve block 44. The function of the guide rod is to limit the movement trajectory of the threaded sleeve block 44, so that it can only move horizontally along the direction of the guide rod, ensuring the stability and accuracy of the movement.

[0026] Both upright plates 15 have irregular grooves on their right ends, and irregular blocks are slidably connected to both irregular grooves. Connecting rods 47 are fixedly connected to the right ends of both irregular blocks. Support plates 48, which are fixedly connected to the right ends of the two connecting rods 47, are fixedly connected to the right ends of the two connecting rods 47. The open design allows the support plates 48 to rise and fall with the cutting action, preventing motion interference. The adjusting threaded rods 42 are more stable when rotating.

[0027] Two telescopic components 45 are symmetrically arranged on the threaded sleeve block 44. The lower ends of the two telescopic components 45 are fixedly connected to a positioning plate 46. The telescopic component 45 includes a fixed rod 451 that is fixedly inserted through the threaded sleeve block 44. The lower end of the fixed rod 451 has a sliding cavity 452. The sliding cavity 452 is slidably connected to a telescopic rod 453. A return spring 454 is fixedly connected between the telescopic rod 453 and the sliding cavity 452. When the return spring 454 is not compressed, the lower end face of the positioning plate 46 is lower than the lower end face of the cutting blade 34. When the equipment drives the cutting blade 34 to descend for cutting, the processing table first contacts the positioning plate 46. The positioning plate 46 first intercepts the right end of the chip. Due to the action of the return spring 454, the positioning plate 46 can adaptively adjust according to the height of the chip to ensure stable interception of the chip. Then the cutting blade 34 cuts. After the cutting is completed, the electric push rod 32 drives the cutting blade 34 to rise, ready for the next cutting operation.

[0028] The cutting component 3 and the length adjustment component 4 are arranged from left to right, so that the chip can pass through the limiting and cutting processes in sequence during the transmission process. By adjusting the length adjustment threaded rod 42, the distance between the positioning plate 46 and the cutting blade 34 can be changed, thereby realizing the adjustment of the chip length and meeting the cutting requirements of chips of different sizes.

[0029] The specific working principle of this invention is as follows: Preparation: Based on the width of the chip to be cut, start the limit motor 25. The limit motor 25 drives the active bevel gear 23 to rotate, which in turn drives the driven bevel gear 24 to rotate synchronously, causing the limit threaded rod 26 to rotate. The threaded sleeve 27 moves on the limit threaded rod 26, and through the sliding rod 28, it drives the two limit plates 29 to move relative to each other or away from each other. Adjust the distance between the two limit plates 29 to match the width of the chip.

[0030] Chip transfer: The chip to be cut is placed on the transfer structure 14. The transfer structure 14 is started and drives the chip to be transferred smoothly from left to right. During the transfer, the two sides of the chip contact the auxiliary wheels 292 on the limiting plate 29. The auxiliary wheels 292 rotate to reduce friction and limit the chip, preventing the chip from shifting during the transfer.

[0031] Adjusting the cutting length: Based on the required chip cutting length, start the length adjustment motor 43, which drives the length adjustment threaded rod 42 to rotate. The threaded sleeve block 44 moves horizontally on the length adjustment threaded rod 42. The guide rod ensures its movement stability. The threaded sleeve block 44 drives the positioning plate 46 to move through the telescopic part 45. Adjust the distance between the positioning plate 46 and the cutting blade 34 to determine the cutting length.

[0032] Chip cutting: The electric push rod 32 is activated, driving the mounting base 33 and the cutting blade 34 to descend. The lower end face of the positioning plate 46 is lower than the lower end face of the cutting blade 34. The positioning plate 46 first contacts and intercepts the right end of the chip. As the cutting blade 34 continues to descend, the reset spring 454 is compressed, and the height of the positioning plate 46 remains unchanged. The cutting blade 34 cuts the chip. After the cutting is completed, the electric push rod 32 drives the cutting blade 34 to rise and reset. At the same time, the reset spring 454 resets, and then drives the positioning plate 46 to return to its original position, facilitating the next cutting.

[0033] Chip unloading: The cut chips continue to be conveyed to the right by the conveyor structure 14 and arrive at the unloading plate 5. Utilizing the tilted structure of the unloading plate 5, which is higher on the left and lower on the right, the chips slide down under the action of gravity, making them easy to collect and not affecting the subsequent cutting work.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
