Description

Technical Field

[0001] The utility model relates to the technical field of chip detection, in particular to a positioning device for detecting a phase change switch chip. Background Art

[0002] A phase change switch chip, as a new type of non-volatile memory, uses the significantly different resistance values of a phase change material in the crystalline state and the amorphous state to store information. This characteristic gives the phase change switch chip unique advantages in the field of information storage, but also poses new challenges to testing technologies and methods. Therefore, detecting the phase change switch chip is a key step to ensure its stable and reliable performance.

[0003] An auxiliary detection and positioning device for chip packaging disclosed in the prior art with the publication number CN217822711U includes a support frame. Both sides of the support frame are provided with bolt assemblies and are movably connected thereto. The bolt assemblies are movably connected to one side of a fixed block. The other side of the fixed block is movably connected to the outer side of a placement turntable. An encapsulation groove is formed in the middle of the placement turntable. A chip packaging body is arranged in the encapsulation groove. A pressing member is arranged above the chip packaging body. Both ends of the pressing member are movably connected to the upper surface of the fixed block.

[0004] Although this detection and positioning device can rotate and flip the chip, during the actual image detection process of the phase change switch chip, it is found that all operations of this detection and positioning device need to be manually performed by workers (such as the initial placement and pressing work, rotation work, and subsequent flipping), which is not only cumbersome but also very time-consuming, undoubtedly reducing the detection efficiency of the phase change switch chip. Therefore, improvements are proposed. Summary of the Utility Model

[0005] The utility model is proposed to solve the shortcomings existing in the prior art, and provides a positioning device for detecting a phase change switch chip.

[0006] To achieve the above object, the utility model adopts the following technical solution: A positioning device for detecting a phase change switch chip includes a base. One side of the top of the base is fixedly installed with a column. The top of the column is fixedly connected with a housing. The housing is equipped with a flipping assembly. The movable end of the flipping assembly is fixedly installed with an electric four-jaw chuck.

[0007] Four movable ends of the electric four-jaw chuck are all fixedly connected with locking members. Long positioning seats are assembled on two relatively locking members, and short positioning seats are assembled on the other two locking members. A phase change switch chip body is jointly abutted between the two long positioning seats and the two short positioning seats.

[0008] A telescopic cylinder penetrating to the top is fixedly installed at the inner bottom of the base. The top of the telescopic cylinder is fixedly connected with a vacuum chuck. A support plate is fixedly sleeved on the outer surface of the vacuum chuck, and the phase change switch chip body is placed on the top of the support plate;

[0009] A vacuum pumping assembly is jointly installed between the vacuum chuck and the base.

[0010] Furthermore, the flipping assembly includes a motor, and the motor is fixedly installed at the inner bottom of the housing. The driving end of the motor is fixedly connected with a driving gear. One side of the outer surface of the driving gear is meshed with a driven gear. One side of the outer surface of the driven gear is fixedly connected with a mounting shaft, and the mounting shaft penetrates through the housing and is fixedly connected with the outer shell of the electric four-jaw chuck, which can drive the electric four-jaw chuck to perform flipping operations.

[0011] Furthermore, the mounting shaft is rotatably connected with the housing, and the housing has a supporting effect on the mounting shaft, which is beneficial to the installation of the mounting shaft.

[0012] Furthermore, each of the four locking members includes a sliding sleeve, and the sliding sleeve is fixedly installed on the top of the adjacent movable ends of the electric four-jaw chuck. The sliding sleeve is slidably sleeved on the outer surfaces of the adjacent long positioning seats and the adjacent short positioning seats. A locking bolt penetrating to the inside is provided at the top of the sliding sleeve, and the locking bolt abuts against the adjacent long positioning seats and the adjacent short positioning seats. Anti-slip threads are provided on the end face of the locking bolt to increase the friction at the abutting place and avoid slipping during use.

[0013] Furthermore, the locking bolt is threadedly connected with the sliding sleeve, and the sliding sleeve can assist the locking bolt to move.

[0014] Furthermore, the vacuum pumping assembly includes a vacuum pump, and the vacuum pump is fixedly installed on one inner wall of the base. The input end of the vacuum pump is fixedly penetrated with a three-way solenoid valve. The other interface of the three-way solenoid valve is fixedly penetrated with a hose, and the hose penetrates through the base and is fixedly penetrated with the vacuum chuck. The setting of the hose can avoid affecting the movement of the vacuum chuck.

[0015] Furthermore, the remaining interface of the three-way solenoid valve is in an open state. After the three-way solenoid valve switches the connected pipelines, when the hose is connected to the open interface, it is convenient for gas to enter the vacuum chuck to release the adsorption state.

[0026] As shown Figures 1 to 3 in the figure, it relates to a positioning device for detecting a phase change switch chip, including a base 1. A column 4 is fixedly installed on one side of the top of the base 1. The top of the column 4 is fixedly connected to a housing 7. The housing 7 is equipped with a flipping assembly. The movable end of the flipping assembly is fixedly installed with an electric four-jaw chuck 6. The flipping assembly includes a motor 19, and the motor 19 is fixedly installed on the inner bottom of the housing 7. The driving end of the motor 19 is fixedly connected to a driving gear 18. One side of the outer surface of the driving gear 18 is meshed with a driven gear 16. One side of the outer surface of the driven gear 16 is fixedly connected to a mounting shaft 17. The mounting shaft 17 penetrates through the housing 7 and is fixedly connected to the outer shell of the electric four-jaw chuck 6. The mounting shaft 17 is rotatably connected to the housing 7. The motor 19 drives the driving gear 18 to rotate. The driving gear 18 drives the mounting shaft 17 to rotate through the driven gear 16. The mounting shaft 17 drives the electric four-jaw chuck 6 to rotate.

[0027] Locking members are fixedly connected to the four movable ends of the electric four-jaw chuck 6. Long positioning seats 9 are assembled with two opposite locking members, and short positioning seats 11 are assembled with the other two locking members. A phase change switch chip body 10 is jointly abutted between the two long positioning seats 9 and the two short positioning seats 11. Each of the four locking members includes a sliding sleeve 8. The sliding sleeve 8 is fixedly installed on the top of the adjacent movable end of the electric four-jaw chuck 6. The sliding sleeve 8 is slidably sleeved on the outer surfaces of the adjacent long positioning seat 9 and the adjacent short positioning seat 11. A locking bolt 12 penetrating to the inside is provided at the top of the sliding sleeve 8. The locking bolt 12 abuts against the adjacent long positioning seat 9 and the adjacent short positioning seat 11. The locking bolt 12 is threadedly connected to the sliding sleeve 8. The locking bolt 12 and the sliding sleeve 8 cooperate to adjust the positions of the long positioning seat 9 or the short positioning seat 11 to meet the actual positioning requirements.

[0028] A telescopic cylinder 3 penetrating to the top is fixedly installed on the inner bottom of the base 1. The top of the telescopic cylinder 3 is fixedly connected to a vacuum chuck 13. A support plate 5 is fixedly sleeved on the outer surface of the vacuum chuck 13. The phase change switch chip body 10 is placed on the top of the support plate 5. The support plate 5 has a supporting effect on the phase change switch chip body 10, which is beneficial for initial placement.

[0029] A vacuum suction cup 13 and a base 1 are jointly installed with a vacuum pumping assembly. The vacuum pumping assembly includes a vacuum pump 15, and the vacuum pump 15 is fixedly installed on an inner wall side of the base 1. The input end of the vacuum pump 15 is fixedly penetrated with a three-way solenoid valve 14. Another interface of the three-way solenoid valve 14 is fixedly penetrated with a hose 2, and the hose 2 penetrates through the base 1 and is fixedly penetrated with the vacuum suction cup 13. The remaining one interface of the three-way solenoid valve 14 is in an open state. When the three-way solenoid valve 14 controls the connection between the vacuum pump 15 and the hose 2, the vacuum pump 15 can perform vacuum pumping on the vacuum suction cup 13 through the hose 2. When the three-way solenoid valve 14 controls the connection between the open state interface and the hose 2, air can enter the vacuum suction cup 13 through the hose 2.

[0030] Working principle: When initially detecting the phase change switch chip body 10 of the same model, the positions of the long positioning seat 9 and the short positioning seat 11 need to be adjusted. Loosen the locking bolt 12, then adjust, and after completion, tighten the locking bolt 12. During the detection process, the staff or an external feeding device places the phase change switch chip body 10 on the pallet 5, and then the electric four-jaw chuck 6 operates to drive the four locking members to approach each other, thereby pushing the long positioning seat 9 and the short positioning seat 11 close to the top of the four sides of the phase change switch chip body 10 until the positioning operation is completed. Then the vacuum pump 15 operates, and the vacuum pump 15 performs vacuum pumping on the vacuum suction cup 13 through the three-way solenoid valve 14 and the hose 2 until the adsorption and fixation of the phase change switch chip body 10 are completed. Then the electric four-jaw chuck 6 resets, and then the detection starts. After the front detection is completed, the electric four-jaw chuck 6 cooperates with each component to position and fix the phase change switch chip body 10 again. Then the vacuum pump 15 stops operating. Then the three-way solenoid valve 14 controls the hose 2 to communicate with the external air to release the adsorption. The telescopic cylinder 3 drives the vacuum suction cup 13 and the pallet 5 to descend until the set position is reached. Then the motor 19 drives the driving gear 18 to rotate, and the driving gear 18 drives the mounting shaft 17 to rotate 180 degrees through the driven gear 16. The mounting shaft 17 drives the electric four-jaw chuck 6 to rotate 180 degrees, and then drives the phase change switch chip body 10 to rotate 180 degrees through each component. Then the telescopic cylinder 3 drives the vacuum suction cup 13 and the pallet 5 to reset until they fit with the phase change switch chip body 10. Then repeat the above detection steps until the back detection of the phase change switch chip body 10 is completed.
