Description

Technical Field

[0001] The utility model relates to the field of chip positioning, in particular to a DDR memory chip production positioning device. Background Art

[0002] During the production and testing process of DDR memory chips, it is usually necessary to position them first, and generally a groove or notch is set on the front as a positioning mark. Since most DDR memory chips are square in design, the vibration plate is first used to arrange and output the chips in an orderly manner with the front side facing up, thereby achieving primary positioning. However, in order to further improve the accuracy of positioning, a visual camera is often required to identify the grooves or notches on the chip. However, this method not only has relatively high equipment costs, but is also easily affected by environmental factors such as light in actual applications, which may affect the accuracy and stability of positioning. Therefore, when designing and implementing DDR memory chip positioning solutions, it is necessary to comprehensively consider multiple factors such as cost, accuracy, and environmental adaptability in order to seek a more economical, efficient and reliable positioning method.

[0003] Therefore, it is necessary to provide a DDR memory chip production positioning device to solve the above technical problems. Utility Model Content

[0005] The utility model provides a DDR memory chip production positioning device, comprising a vibration plate and a mounting frame, wherein the output end of the vibration plate is provided with a discharge trough plate, the end of the discharge trough plate is fixed with a blocking portion for blocking the chip, a stepper motor is fixed at the top center of the mounting frame, a mounting plate is fixed at the end of the output shaft of the stepper motor, a suction component is installed on the mounting plate, the suction component comprises a control motor fixed on the top of the mounting plate, a cylinder is fixed to the output shaft of the control motor, a fixing plate is fixed to the end of the output shaft of the cylinder, a suction cup is fixed to the bottom center of the fixing plate, four corners of the fixing plate are slidably connected with extrusion rods for cooperating with chip positioning grooves, a connecting plate is fixed on the output shaft of the cylinder, pressure sensors are fixed at the connection plate facing the extrusion rod, and a spring is installed between the extrusion rod and the input end of the pressure sensor.

[0016] Compared with the related art, the utility model provides the following beneficial effects:

[0017] Memory chip arrangement and preliminary positioning:

[0018] The chips are placed in the vibration plate, and through the vibration, the chips are arranged in an orderly manner in the discharge chute plate with the front side facing up. The blocking part at the end of the discharge chute plate effectively blocks the chips, ensuring that the chips are arranged in the preset manner, although the initial direction of the chips in the discharge chute plate may be uncertain.

[0019] Memory chip identification and precise positioning:

[0020] When the chip reaches the bottom of the suction assembly, the suction assembly starts working. The four corners of the fixed plate in the suction assembly are slidably connected with extrusion rods, which cooperate with the positioning groove of the chip (set at a corner of the front of the chip). The cylinder drives the fixed plate and the suction cup to move downward. The extrusion rod first contacts the chip and compresses the spring, and then the suction cup firmly sucks the chip. During this process, the pressure sensor detects the pressure changes caused by the contact between the extrusion rod and the chip in real time, and transmits the signal to the controller. The controller determines the position of the positioning groove based on the information detected by the pressure sensor, thereby determining the exact direction of the chip.

[0026] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0027] Please refer to Figures 1 to 4 , a DDR memory chip production positioning device, including a vibration plate 1 and a mounting frame 2. The output end of the vibration plate 1 is equipped with a discharge chute plate 3, and the end of the discharge chute plate 3 is fixed with a blocking portion 4, which is used to effectively block the chip and ensure that the chip can be arranged in a preset manner. In actual operation, the chip is placed in the vibration plate 1. With the help of the vibration of the vibration plate 1, the chip will be arranged in an orderly manner in the discharge chute plate 3 with the front side facing up. Considering that the chip is square in design and a positioning groove is specially provided in one corner of its front side, this detail facilitates subsequent precise positioning. Since the front of the chip is square and the surface is relatively smooth, the direction of the chip in the discharge chute plate 3 is uncertain and requires further positioning.

[0028] The stepper motor 5 is firmly installed at the top center of the mounting frame 2, and the output shaft end of the stepper motor 5 is closely connected to the mounting plate 6. On the mounting plate 6, the utility model carefully designs two suction components 7, which are symmetrically distributed at both ends of the mounting plate 6 to ensure the balance and efficiency of the work. The main responsibility of the two suction components 7 is to accurately transport the DDR memory chip chips to the work station 22 on the rotating table 20 alternately, thereby realizing the smooth progress of the production process.

[0029] Specifically, the design of the suction assembly 7 includes key components such as a control motor 8, a cylinder 9, a fixing plate 10, and a suction cup 11. The control motor 8 is firmly fixed on the top of the mounting plate 6, and the cylinder 9 is closely connected to the output shaft of the control motor 8. The end of the output shaft of the cylinder 9 is connected to the fixing plate 10, and a suction cup 11 is installed at the bottom center of the fixing plate 10 for sucking the chip.

[0030] In order to perfectly match with the positioning groove of the chip, the four corners of the fixing plate 10 are slidably connected with the squeezing rods 12 .

[0031] Pressure sensors 14 (four pressure sensors 14 in total) are fixed to the connecting plate 13 facing the extrusion rods 12, and springs 15 are installed between the extrusion rods 12 and the input ends of the pressure sensors 14. When the cylinder 9 drives the fixing plate 10 and the suction cup 11 to move downward together, three of the extrusion rods 12 will first contact the chip, and then another extrusion rod will also contact the chip, and the spring 15 will be compressed. Then, the suction cup 11 will firmly suck the chip. During this process, the pressure sensor 14 will transmit the signal to the controller 16 in real time. The controller 16 determines the position of the positioning groove according to the information detected by the pressure sensor 14, and the controller 16 controls the rotation of the control motor 8 according to the received signal (the four pressure sensors 14 are represented by A, B, C, and D respectively. When the pressure values ​​of A, B, and C are consistent and the pressure value of D is the smallest, the control motor 8 does not rotate; when the pressure values ​​of B, C, and D are consistent and the pressure value of A is the smallest, the control motor 8 rotates 90 degrees counterclockwise; when the pressure values ​​of C, D, and A are consistent and the pressure value of B is the smallest, the control motor 8 rotates 180 degrees counterclockwise; when the pressure values ​​of A, B, D are consistent and the pressure value of C is the smallest, the control motor 8 rotates 270 degrees counterclockwise) to rotate it to a position matching the work station 22, thereby ensuring the accurate placement of the chip.

[0032] In addition, a controller 16 is installed on the mounting frame 2, which is responsible for electrically connecting the pressure sensor 14 and the control motor 8 to realize the intelligent control of the entire system. The design of the mounting frame 2 is also quite ingenious. It adopts a stable combination of an H-shaped frame 17 and a support leg 18, which not only ensures the stability of the structure, but also takes into account the convenience of use.

[0033] The device also includes a base 19, on which a rotating table 20 is provided, and a rotating motor 21 is fixed inside the base 19. The output shaft of the rotating motor 21 is closely connected to the center of the rotating table 20, so that the rotating table 20 can rotate smoothly. On the top of the rotating table 20, we fixed a plurality of workstations 22 at equal angles for placing and processing chips.

[0034] It is worth mentioning that the blocking part 4 and the discharge chute plate 3 adopt an integrated structural design, which not only enhances the stability of the structure, but also improves the convenience of use. At the same time, a support part 23 is also provided at the end of the discharge chute plate 3, which provides a strong guarantee for the smooth discharge of the chip. In actual operation, one of the suction components 7 will be set directly opposite one of the workstations 22, ensuring that the chip can be accurately and quickly transported to the designated position.

Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
