Description

Technical Field

[0001] The invention relates to the technical field of chip burning test, and in particular to a chip burning test machine. Background Art

[0002] Chip burning test mainly burns the program code into the chip and performs corresponding tests to ensure its normal operation. Chip burning test is a key step to verify the correctness of the chip program code. By burning data and electrical testing on the chip, it can be ensured that the software in the chip is correct and can perform its functions as expected. This helps to reduce the product failure rate caused by software errors, thereby improving the overall product quality.

[0003] Existing chip burning test machines usually use a single suction cup to fix the chip and move it to the burning test area for operation. However, when a rectangular memory chip needs to be fixed by suction, only one suction cup is used to fix it in the middle. This may cause the two ends of the rectangular memory chip to shake and become unstable during the movement, thus affecting the accuracy of inserting the chip into the burning test area. 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 the formation of 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 effect of the adsorption force. Summary of the invention

[0022] The telescopic ends of the two hydraulic cylinders 6 are provided with an adjustable fixing mechanism, which includes two fixing boxes 9. Two suction cups 8 are movably provided on the inner side of the fixing box 9.

Start the vacuum pump 27, open the solenoid valves inside the two L-shaped air ducts 23 at the same time, and close the solenoid valve inside the hose 2, so that the vacuum pump 27 delivers suction wind to the two second telescopic tubes 24 through the mounting tube 26 and the T-shaped tube 25. The two second telescopic tubes 24 then pass through the two L-shaped air ducts 23 to the two first telescopic tubes 22, and then pass through the first telescopic tubes 22 to the connecting tubes 21, thereby evacuating the air inside the suction cup 8 to a vacuum state, allowing the suction cup 8 to be tightly adsorbed on the upper end surface of the rectangular memory chip.

[0024] A cleaning mechanism is provided at the right side of a fixed box 9, and the cleaning mechanism includes two first rotating shafts 10, and the outer surfaces of the two first rotating shafts 10 are jointly covered with thickened non-woven fabrics 11. The cleaning mechanism cooperates with the lateral moving mechanism and the vertical moving mechanism, and can effectively wipe 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 fixed rods 28, and the two fixed rods 28 are fixedly connected to the upper end of the right fixed box 9 through a connecting seat, and the right ends of the two fixed rods 28 are fixedly connected to a pushing seat 30, and a connecting shaft 31 is rotatably installed on the inner side of the pushing seat 30, and a rotating motor 32 is fixedly connected to the front end of the connecting shaft 31. The bottom side of the rotating motor 32 is fixedly installed on the front side of the pushing seat 30 through a fixing part, and a rotating frame 33 is fixedly covered on the outer surface of the connecting shaft 31. When the two rectangular memory chips are wiped, the rotating motor 32 is started, and the rotating motor 32 drives the rotating frame 33 to rotate 90 degrees counterclockwise upward.

[0025] A cleaning seat 36 is fixedly connected to the bottom end of the rotating frame 33, and the rear side of the cleaning seat 36 is slidably matched with the outer surfaces of the two first rotating shafts 10, and the front side of the cleaning seat 36 is correspondingly rotatably installed with two second rotating shafts 40, and the rear ends of the two first rotating shafts 10 are rotatably connected with a pull ring, and the rear end of the second rotating shaft 40 is fixedly installed with a spline block, and the front end of the first rotating shaft 10 is correspondingly provided with a spline slot that is engaged with the spline block, and the outer surfaces of the two second rotating shafts 40 are respectively covered with synchronous wheels 41, and the outer extensions of the two synchronous wheels 41 are synchronously connected through a synchronous belt 42, and the front end of a second rotating shaft 40 is fixedly connected to a driving motor 43, and the upper side of the driving motor 43 is fixedly installed on the front side of the cleaning seat 36 through a fixing part. Each time a rectangular memory chip is cleaned, the drive motor 43 is started, and the drive motor 43 drives the second rotating shaft 40 on the upper side to rotate, and the second rotating shaft 40 on the upper side drives the synchronous wheel 41 on the upper side to rotate, and the synchronous wheel 41 on the upper side drives the synchronous wheel 41 below to rotate through the synchronous belt 42, so that the two second rotating shafts 40 rotate, and the two second rotating shafts 40 drive the two first rotating shafts 10 to rotate, so that the two first rotating shafts 10 perform cloth retracting and releasing operations respectively, so that the used non-woven fabric 11 set on the outer surface of the first rotating shaft 10 below moves upward to a certain distance, so that the non-woven fabric 11 for subsequent cleaning of the rectangular memory chip is always in the clean part.

[0026] A dust box 44 is fixedly installed on the right side of the cleaning seat 36 and near the bottom end, a ventilation pipe 45 is fixedly installed on the upper end of the dust box 44, a telescopic hose 46 is fixedly connected to the upper end of the ventilation pipe 45, an air guide box 47 is fixedly connected to the upper end of the telescopic hose 46, the air guide box 47 is fixedly installed on the left side of the pushing seat 30, a support tube 48 is fixedly connected to the left side of the air guide box 47, the left end of the support tube 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 frame is arranged inside the filter box 39, a filter cloth is fixedly installed on the left side of the filter frame, a hose 2 is fixedly connected to the left side of the filter box 39, 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, and a solenoid valve is arranged inside the hose 2. The non-woven fabric 11 is driven by the lateral moving mechanism to wipe horizontally along the upper end surface of the rectangular memory chip, thereby effectively erasing 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 will remain on the upper end surface of the rectangular memory. At this time, the vacuum pump 27 is started, and the vacuum pump 27 delivers suction wind to the two second telescopic tubes 24 through the mounting tube 26 and the T-tube 25. At this time, the electromagnetic valves inside the two L-shaped air guide tubes 23 are closed, and the electromagnetic valve inside the hose 2 is opened, so that the suction wind is concentrated into the hose 2, and then concentrated into the dust box 44 through the support tube 48, the telescopic hose 46 and the ventilation tube 45. The dust box 44 then sucks the dust and oxides remaining 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 frame set inside the filter box 39, which is convenient for subsequent centralized processing.

[0027] During use, the chip placement plate 38 with the rectangular memory chip is placed on the bracket 37, and the third servo motor 29 is started. The third servo motor 29 drives the third screw rod 7 to rotate, so that the bracket 37 drives the chip placement plate 38 to move to the bottom of the adjustable fixing mechanism. Before the suction cup 8 adsorbs and fixes the rectangular memory chip, the lateral moving mechanism drives the cleaning mechanism to move to the top of the first rectangular memory chip, and then the hydraulic cylinder 6 on the right side is started, so that the hydraulic cylinder 6 on the right side drives the fixing box 9 and the cleaning mechanism set on the right side of the fixing box 9 to move downward, so that the bottom of the non-woven fabric 11 wound on the first rotating shaft 10 below and set in the cleaning mechanism is close to the upper end surface of the rectangular memory chip, and then the non-woven fabric 11 is driven by the lateral moving mechanism to wipe horizontally along the upper end surface of the rectangular memory chip, so as to effectively wipe 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 will remain on the upper end surface of the rectangular memory. At this time, the vacuum pump 27 is started, and the vacuum pump 27 delivers suction wind to the two second telescopic tubes 24 through the installation tube 26 and the T-tube 25. At this time, the electromagnetic valves inside the two L-shaped air guide tubes 23 are closed, and the electromagnetic valve inside the hose 2 is opened, so that the suction wind is concentrated into the hose 2, and then concentrated into the dust box 44 through the support tube 48, the telescopic hose 46 and the ventilation tube 45. The dust box 44 then absorbs the dust and oxides remaining 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 frame set inside the filter box 39, which is convenient for subsequent centralized processing; Each time a rectangular memory chip is cleaned, the driving motor 43 is started, and the driving motor 43 drives the second rotating shaft 40 on the upper side to rotate, and the second rotating shaft 40 on the upper side drives the synchronous wheel 41 on the upper side to rotate, and the synchronous wheel 41 on the upper side drives the synchronous wheel 41 below to rotate through the synchronous belt 42, so that the two second rotating shafts 40 rotate, and the two second rotating shafts 40 drive the two first rotating shafts 10 to rotate, so that the two first rotating shafts 10 respectively perform cloth retracting and releasing operations, so that the used non-woven fabric 11 set on the outer surface of the lower first rotating shaft 10 moves upward to a certain distance, so that the non-woven fabric 11 for subsequent cleaning of the rectangular memory chip is always in the clean part, and when the two rectangular memory chips are wiped, the rotating motor 32 is started, and the rotating motor 32 drives the rotating frame 33 to rotate 90 degrees counterclockwise upward; Afterwards, the two hydraulic cylinders 6 are moved to the corresponding positions above the two rectangular memory chips through the lateral moving mechanism. 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 move closer to or away from each other to a suitable 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 closely attached to the upper end surfaces of the corresponding rectangular memory chips. Then, the vacuum pump 27 is started, and the solenoid valves inside the two L-shaped air ducts 23 are opened at the same time, and the solenoid valve inside the hose 2 is closed, so that the suction wind passes through the two L-shaped air ducts 23 to the two first telescopic tubes 22, and then passes through the first telescopic tubes 22 to the connecting tube 21, so that the air inside the suction cup 8 is evacuated to a vacuum state, so that the suction cup 8 is tightly adsorbed on the upper end surface of the rectangular memory chip. Afterwards, through the cooperation of the vertical moving mechanism and the horizontal moving mechanism, the rectangular memory chip fixed by the suction cup 8 is moved to the corresponding firing test station 4. After the firing test of the rectangular memory chip is completed, the rectangular memory chip that passes the firing test is placed back into the placement slot in the corresponding chip placement tray 38 through the suction cup 8, and the rectangular memory chip that fails the firing test is placed into the defective collection box installed on the right side of the bracket 37 through the suction cup 8. Repeat the above operation, and perform end face cleaning and mobile firing test operations on other rectangular memory chips in turn.
