[0028] Please refer to Figures 1-5 , the present utility model provides a technical solution:
[0029] A position-calibratable chip burning positioning device, including a positioning device body 1 and a connecting block 2. The connecting block 2 is installed at the upper end of the positioning device body 1. One side of the connecting block 2 is fixedly connected with an electric telescopic rod 3. The bottom end of the electric telescopic rod 3 is fixedly connected with a ventilation component 4. The top end of the ventilation component 4 is fixedly connected with a suction pump 5. The bottom end of the ventilation component 4 is fixedly connected with a calibration device 6. The bottom end of the ventilation component 4 is fixedly connected with a suction cylinder 7. The bottom end of the suction cylinder 7 is fixedly connected with a suction cup 8. The ventilation component 4 includes a gas guide shell 41. A first ventilation channel 42 is opened inside the gas guide shell 41. A second ventilation channel 43 is opened inside the gas guide shell 41. A solenoid valve 44 is fixedly connected inside the first ventilation channel 42 opened in the gas guide shell 41. A connecting channel 45 is opened inside the lower end of the gas guide shell 41. The calibration device 6 includes an inner hole shell 61. A double solid rod 64 is slidably connected inside the inner hole shell 61. The top end of the double solid rod 64 is fixedly connected with a spring 62. An activity groove 63 is opened inside the inner hole shell 61. A sealing ring 65 is fixedly connected to the outside of the double solid rod 64. The bottom end of the double solid rod 64 is fixedly connected with a rubber ball 66. A ventilation hole 67 is opened inside the inner hole shell 61.
[0030] As a further implementation of this solution, an ear seat is fixedly connected to the rear end of the gas guide shell 41. The gas guide shell 41 is fixed to the bottom end of the electric telescopic rod 3 through the ear seat, which is convenient for driving the gas guide shell 41 to move after starting the electric telescopic rod 3, so that the suction cup 8 contacts the chip.
[0031] As a further implementation of this solution, the first ventilation channel 42 runs through the inside of the gas guide shell 41. The number of the first ventilation channels 42 is two. The first ventilation channels 42 are opened inside the left end and the right end of the gas guide shell 41. The number of the first ventilation channels 42 corresponds to the number of the solenoid valves 44 one by one. The opening shape of the first ventilation channel 42 is two sections of cylinders, which is convenient for the air communication between the suction cylinder 7 and the inside of the inner hole shell 61, and at the same time convenient for the inner hole shell 61 to communicate with the outside air.
[0032] As a further implementation of this solution, the upper end of the inner hole shell 61 is fixedly connected to the inside of the lower end of the first ventilation channel 42. The number of the inner hole shells 61 corresponds to the number of the first ventilation channels 42 one by one. The shape of the inner hole shell 61 is a hollow cylinder. After starting the suction pump 5, the double solid rod 64 is received into the inside of the inner hole shell 61 to prevent it from affecting the contact between the suction cup 8 and the chip.
[0033] As a further implementation of this solution, the ventilation hole 67 is communicated with the inside of the suction cylinder 7 through the connecting channel 45. The ventilation hole 67 is opened inside the suction cylinder 7. The number of the ventilation holes 67 inside the suction cylinder 7 corresponds to the number of the ventilation holes 67 inside the inner hole shell 61 one by one. The inside of the suction cylinder 7 is hollow. The lower end of the suction cylinder 7 is a through structure. The inside of the inner hole shell 61 is communicated with the ventilation hole 67. Under the suction effect of the suction pump 5, the air inside the activity groove 63 and the air inside the suction cylinder 7 are discharged, realizing the function of adsorbing and fixing the chip.
[0034] As a further implementation of this solution, the opening shape of the second ventilation channel 43 is two sections of cylinders. The upper end of the suction cylinder 7 is fixed inside the second ventilation channel 43 opened in the air guide shell 41. The second ventilation channel 43 runs through the inside of the air guide shell 41. The suction pump 5 is connected to the inside of the suction cylinder 7 through the second ventilation channel 43. It is possible to control the connection of the movable groove 63 with the external gas, facilitating the downward movement of the double solid rod 64 and the rubber ball 66 through the spring 62.
[0035] As a further implementation of this solution, the shape of the double solid rod 64 is two sections of cylinders. The outer side of the sealing ring 65 fits with the inner side of the movable groove 63 opened in the inner hole shell 61. The opening shape of the movable groove 63 is two sections of cylinders. The upper end of the spring 62 is fixedly connected to the upper end of the movable groove 63 opened in the inner hole shell 61, realizing the function of calibration, preventing the occurrence of movement and offset between the chip and the chip slot, and ensuring the qualified rate of the processed chips.
[0036] Working process: When the device is in use, it is externally powered on. When adsorbing and fixing the chip, the installation displacement on one side of the connecting block 2 is controlled through the positioning device body 1 and the connecting block 2, and the lifting of the ventilation assembly 4 is controlled through the electric telescopic rod 3. When the suction cup 8 contacts the chip, the suction pump 5 is started. The suction pump 5 continuously sucks through the second ventilation channel 43 opened in the air guide shell 41 into the inside of the suction cylinder 7. At this time, a negative pressure is formed inside the suction cylinder 7 and the suction cup 8, enabling the suction cup 8 to adsorb and fix the chip. At the same time, a negative pressure is generated inside the movable groove 63 opened in the inner hole shell 61, and the gas inside the movable groove 63 enters the inside of the suction cylinder 7 through the ventilation hole 67 and the connecting channel 45. Under the action of the negative pressure, the double solid rod 64 moves upward. The double solid rod 64 is slidably connected to the inner side of the inner hole shell 61. The double solid rod 64 is sealed with the inner hole shell 61 through the sealing ring 65. The double solid rod 64 squeezes the spring 62. After the adsorption and fixation are completed, the fixed chip is moved through the positioning device body 1 and the connecting block 2. When the chip moves to the upper end of the programming seat, the solenoid valve 44 is opened. At this time, the negative pressure in the movable groove 63 and the first ventilation channel 42 is weakened, while there is still negative pressure inside the suction cylinder 7 and the suction cup 8, and the chip still closely adheres to the suction cup 8. Under the action of the elastic force of the spring 62, the double solid rod 64 is pushed to move, and the double solid rod 64 drives the rubber ball 66 to move. At this time, when the rubber ball 66 contacts the chip, the rubber ball 66 plays a role in protecting the chip, with a certain buffering performance. The suction pump 5 is stopped. Under the thrust of the rubber ball 66, the chip stably contacts the programming seat, realizing the function of calibration, preventing the occurrence of movement and offset between the chip and the chip slot, and ensuring the qualified rate of the processed chips.
