Description

Technical Field

[0001] The present invention relates to the technical field of chip programming and testing, and particularly to a chip programming and testing machine. Background Art

[0002] Chip programming and testing mainly involves programming code into a chip and performing corresponding tests to ensure its normal operation. Chip programming and testing is a crucial step in verifying the correctness of the chip program code. By programming data into the chip and performing electrical tests, it can be ensured that the software in the chip is correct and can execute its functions as expected. This helps reduce the product failure rate caused by software errors, thereby improving the overall product quality.

[0003] Existing chip programming and testing machines usually use a single suction cup to fix the chip and move it to the programming and testing area for operation. However, when it is necessary to adsorb and fix a rectangular memory chip, only using one suction cup to adsorb it in the middle position may cause the two ends of the rectangular memory chip to shake unstably during the subsequent movement, which may affect the accuracy of inserting the chip into the programming and testing area;

[0004] In addition, the rectangular memory chip contains metal components. After long-term contact with oxygen in the air, the metal components will undergo an oxidation reaction, resulting in uneven oxides on the chip surface. At the same time, dust and impurities in the air may also adhere to the surface of the rectangular memory chip. These factors may cause uneven or incomplete contact between the suction cup and the chip surface, thereby affecting the stability and effectiveness of the adsorption force. Summary of the Invention

A chip placement tray 38 is placed on the upper end of the support base 37. A plurality of placement grooves are formed on the upper surface of the chip placement tray 38. A defective product collection box is placed on the right side of the support base 37. Place the chip placement tray 38 with rectangular memory chips on the support base 37, start the third servo motor 29, and the third servo motor 29 drives the third lead screw 7 to rotate, so that the support base 37 drives the chip placement tray 38 to move vertically forward.

The bottom side of the second servo motor 18 is fixedly installed with a fixing member. The left end of the fixing member is in sliding cooperation with the moving groove formed at the corresponding position on the right side of the machine housing 1. A moving seat 5 in threaded cooperation is sleeved on the outer surface of the second lead screw 17. Start the second servo motor 18, and the second servo motor 18 drives the second lead screw 17 to rotate, so that the moving seat 5 drives the mechanism installed on the moving seat 5 to move horizontally above the processing table 3.

[0033] The telescopic ends of two hydraulic cylinders 6 are provided with an adjustable fixing mechanism. The adjustable fixing mechanism includes two fixing boxes 9. Two suction cups 8 are movably arranged inside the fixing boxes 9. After the two suction cups 8 are appropriately close to or away from each other, the rectangular memory chip can be effectively and stably adsorbed and fixed. The adjustable fixing mechanism further includes two threaded rods 34. The two ends of the two threaded rods 34 are respectively rotationally matched with the inner sides of the two fixing boxes 9. The rear ends of the threaded rods 34 are fixedly connected with a first motor 19. The upper side of the first motor 19 is fixedly installed at the rear side of the fixing box 9 through a fixing piece. At the upper end surfaces of the two fixing boxes 9 and near the rear side, sliding plates are respectively fixedly installed. The sliding plates are slidably matched with the sliding grooves formed inside the moving seat 5. The telescopic end of the hydraulic cylinder 6 is fixedly connected to the middle of the upper end surface of the fixing box 9. Two sliding members 20 are sleeved on the outer surfaces of the threaded rods 34. The two sides of the sliding members 20 are slidably matched with the inner sides of the fixing boxes 9. The bottom ends of the two sliding members 20 are respectively fixedly installed with connecting pipes 21. The bottom ends of the connecting pipes 21 are fixedly connected with suction cups 8. According to the length of the rectangular memory chip, the first motor 19 is started. The first motor 19 drives the threaded rod 34 to rotate, so that the threaded rod 34 drives the two sliding members 20 to approach or move away from each other to a proper position. Then the hydraulic cylinder 6 continues to drive the two suction cups 8 to move downward, so that the bottom ends of the two suction cups 8 are tightly attached to the upper end surfaces of the corresponding rectangular memory chips.

[0034] The two connecting pipes 21 are fixedly connected through a first telescopic pipe 22. L-shaped air guide pipes 23 are respectively fixedly connected to the inner sides of the two first telescopic pipes 22. Solenoid valves are respectively arranged inside the L-shaped air guide pipes 23 and near the lower part. The upper ends of the L-shaped air guide pipes 23 are fixedly connected with second telescopic pipes 24. The upper ends of the two second telescopic pipes 24 are fixedly connected with a T-shaped pipe 25. The upper ends of the two second telescopic pipes 24 and the T-shaped pipe 25 are jointly fixedly installed at the front side of the moving seat 5 through a connecting seat. The rear end of the T-shaped pipe 25 is fixedly connected to the air suction end of a vacuum pump 27 through an installation pipe 26. The vacuum pump 27 is fixedly installed on the upper end surface of the moving seat 5. The vacuum pump 27 is started, and at the same time, the solenoid valves inside the two L-shaped air guide pipes 23 are opened, and the solenoid valve inside the hose 2 is closed, so that the vacuum pump 27 conveys suction air to the two second telescopic pipes 24 through the installation pipe 26 and the T-shaped pipe 25. The two second telescopic pipes 24 respectively lead to the two first telescopic pipes 22 through the two L-shaped air guide pipes 23, and then respectively lead to the connecting pipes 21 through the first telescopic pipes 22, so as to pump the air inside the suction cups 8 to a vacuum state, and make the suction cups 8 tightly adsorb on the upper end surfaces of the rectangular memory chips.

[0035] A cleaning mechanism is provided on the right side of a fixed box 9. The cleaning mechanism includes two first rotating shafts 10. A thick non-woven fabric 11 is sleeved on the outer surfaces of the two first rotating shafts 10. The cleaning mechanism cooperates with the horizontal moving mechanism and the vertical moving mechanism, and can effectively wipe off the dust and oxides on the upper end surface of the rectangular memory chip through the non-woven fabric 11. The cleaning mechanism also includes two fixing rods 28. The two fixing rods 28 are fixedly connected to the upper end of the right fixed box 9 through a connecting seat. The right ends of the two fixing rods 28 are fixedly connected with a pushing seat 30. A connecting shaft 31 is rotatably installed inside the pushing seat 30. The front end of the connecting shaft 31 is fixedly connected with a rotating motor 32. The bottom side of the rotating motor 32 is fixedly installed on the front side of the pushing seat 30 through a fixing member. A rotating frame 33 is fixedly sleeved on the outer surface of the connecting shaft 31. When the wiping of the two rectangular memory chips is completed, the rotating motor 32 is started, and the rotating motor 32 drives the rotating frame 33 to rotate counterclockwise upward by 90 degrees.

[0036] The bottom end of the rotating frame 33 is fixedly connected with a cleaning seat 36. The rear side of the cleaning seat 36 is slidably matched with the outer surfaces of the two first rotating shafts 10. And two second rotating shafts 40 are rotatably installed corresponding to the front side of the cleaning seat 36. A pull ring is rotatably connected to the rear ends of the two first rotating shafts 10. A spline chuck is fixedly installed at the rear end of the second rotating shaft 40. A spline groove for clamping and matching with the spline chuck is correspondingly formed at the front end of the first rotating shaft 10. Synchronous wheels 41 are sleeved on the outer surfaces of the two second rotating shafts 40 respectively. The outer extensions of the two synchronous wheels 41 are synchronously connected through a synchronous belt 42. The front end of one second rotating shaft 40 is fixedly connected with a driving motor 43. The upper side of the driving motor 43 is fixedly installed on the front side of the cleaning seat 36 through a fixing member. For each rectangular memory chip cleaned, the driving motor 43 is started. The driving motor 43 drives the upper second rotating shaft 40 to rotate. The upper second rotating shaft 40 then drives the upper synchronous wheel 41 to rotate. The upper synchronous wheel 41 then drives the lower synchronous wheel 41 to rotate through the synchronous belt 42, so that the two second rotating shafts 40 rotate. The two second rotating shafts 40 also drive the two first rotating shafts 10 to rotate, so that the two first rotating shafts 10 respectively perform the operations of taking in and releasing the cloth, so that the used non-woven fabric 11 sleeved on the outer surface of the lower first rotating shaft 10 moves upward by a certain distance, so that the non-woven fabric 11 for subsequent cleaning of the rectangular memory chip is always in the clean part.

[0037] A dust suction box 44 is fixedly installed on the right side and near the bottom end of the cleaning base 36. A ventilation pipe 45 is fixedly installed at the upper end of the dust suction box 44. The upper end of the ventilation pipe 45 is fixedly connected to a telescopic hose 46. The upper end of the telescopic hose 46 is fixedly connected to a wind guide box 47. The wind guide box 47 is fixedly installed on the left side of the pushing base 30. A support pipe 48 is fixedly connected to the left side of the wind guide box 47. The left end of the support pipe 48 is fixedly connected to the right side of the filter box 39. The filter box 39 is fixedly installed on one side of the right fixed box 9. A filter rack is arranged inside the filter box 39. A filter cloth is fixedly installed on the left side of the filter rack. The left side of the filter box 39 is fixedly connected to a hose 2. The left end of the hose 2 is fixedly connected to one side of the L-shaped air guide pipe 23 on the right side. An electromagnetic valve is arranged inside the hose 2. The non-woven fabric 11 is driven by a lateral movement mechanism to wipe horizontally along the upper end surface of the rectangular memory chip, so as to effectively wipe off the dust and oxides on the upper end surface of the rectangular memory chip. During the wiping process, most of the dust and oxides will adhere to the non-woven fabric 11, and only a small part remains on the upper end surface of the rectangular memory. At this time, the vacuum pump 27 is started. The vacuum pump 27 conveys suction air to the two second telescopic pipes 24 through the installation pipe 26 and the T-shaped pipe 25. At this time, the electromagnetic valves inside the two L-shaped air guide pipes 23 are closed, and the electromagnetic valve inside the hose 2 is opened, so that the suction air is concentrated and led into the hose 2, and then is concentrated and led into the dust suction box 44 through the support pipe 48, the telescopic hose 46 and the ventilation pipe 45. The dust suction box 44 then sucks the remaining dust and oxides on the upper end surface of the rectangular memory chip into the filter box 39, and filters them through the filter cloth on the filter rack arranged inside the filter box 39, which is convenient for subsequent centralized treatment.

[0038] During use, the chip placement tray 38 with rectangular memory chips placed thereon is placed on the bracket 37. The third servo motor 29 is started, and the third servo motor 29 drives the third lead screw 7 to rotate, causing the bracket 37 to drive the chip placement tray 38 to move to a position below the adjustable fixing mechanism. Before the suction cup 8 adsorbs and fixes the rectangular memory chip, the lateral movement mechanism drives the cleaning mechanism to move above the first rectangular memory chip. Then, the hydraulic cylinder 6 on the right side is started, causing the hydraulic cylinder 6 on the right side to drive the fixing box 9 and the cleaning mechanism provided on the right side of the fixing box 9 to move downward, so that the bottom of the non-woven fabric 11 wound around the lower first rotating shaft 10 in the cleaning mechanism closely adheres to the upper end surface of the rectangular memory chip. Then, the lateral movement mechanism drives the non-woven fabric 11 to wipe horizontally along the upper end surface of the rectangular memory chip, thereby effectively wiping off the dust and oxides on the upper end surface of the rectangular memory chip. During the wiping process, most of the dust and oxides will adhere to the non-woven fabric 11, and only a small part remains on the upper end surface of the rectangular memory. At this time, the vacuum pump 27 is started, and the vacuum pump 27 conveys suction air to the two second telescopic tubes 24 through the installation pipe 26 and the T-shaped pipe 25. At this time, the solenoid valves inside the two L-shaped air ducts 23 are closed, and the solenoid valve inside the hose 2 is opened, so that the suction air is concentrated and led into the hose 2, and then through the support pipe 48, the telescopic hose 46 and the ventilation pipe 45, it is concentrated and led into the dust suction box 44. The dust suction box 44 then sucks the remaining dust and oxides on the upper end surface of the rectangular memory chip into the filter box 39 and filters them down through the filter cloth on the filter rack provided inside the filter box 39, which is convenient for subsequent centralized treatment;

[0039] After cleaning each rectangular memory chip, the drive motor 43 is started. The drive motor 43 drives the upper second rotating shaft 40 to rotate. The upper second rotating shaft 40 then drives the upper synchronous pulley 41 to rotate. The upper synchronous pulley 41 then drives the lower synchronous pulley 41 to rotate through the synchronous belt 42, so that the two second rotating shafts 40 rotate. The two second rotating shafts 40 drive the two first rotating shafts 10 to rotate, causing the two first rotating shafts 10 to respectively perform the operations of winding and unwinding the cloth, so that the used non-woven fabric 11 sleeved on the outer surface of the lower first rotating shaft 10 moves upward by a certain distance, ensuring that the non-woven fabric 11 for subsequent cleaning of the rectangular memory chip is always in a clean part. After wiping two rectangular memory chips, the rotating motor 32 is started, and the rotating motor 32 drives the rotating frame 33 to rotate counterclockwise upward by 90 degrees;

[0040] Afterwards, the two hydraulic cylinders 6 are moved to the corresponding positions above the two rectangular memory chips through the lateral movement mechanism. According to the length of the rectangular memory chips, the first motor 19 is started. The first motor 19 drives the threaded rod 34 to rotate, so that the threaded rod 34 drives the two sliding members 20 to approach or move away from each other to an appropriate position. Then, the hydraulic cylinders 6 continue to drive the two suction cups 8 to move downward, so that the bottoms of the two suction cups 8 are closely attached to the upper end surfaces of the corresponding rectangular memory chips. Then, the vacuum pump 27 is started, and at the same time, the solenoid valves inside the two L-shaped air ducts 23 are opened, and the solenoid valve inside the hose 2 is closed, so that the suction air passes through the two L-shaped air ducts 23 to the two first telescopic tubes 22 respectively, and then passes through the first telescopic tubes 22 to the connecting tubes 21 respectively, thereby pumping the air inside the suction cups 8 to a vacuum state, and making the suction cups 8 tightly adsorb on the upper end surfaces of the rectangular memory chips;

[0041] Afterwards, through the cooperation of the vertical movement mechanism and the lateral movement mechanism, the rectangular memory chip adsorbed and fixed by the suction cup 8 is moved to the corresponding firing and testing station 4. After the firing and testing of the rectangular memory chip is completed, the qualified rectangular memory chip after firing and testing is placed back into the placement groove in the corresponding chip placement tray 38 through the suction cup 8, and the unqualified rectangular memory chip after firing and testing is placed into the defective product collection box installed on the right side of the support 37 through the suction cup 8. Repeat the above operations to perform end face cleaning and moving firing and testing operations on other rectangular memory chips in turn.
