[0027] Please refer to Figure 6 and Figure 7 As shown, the interior of the mounting member 411 is rotatably connected to a rotating ring gear 412, and a bottom frame 415 is welded to the bottom of the rotating ring gear 412. A first drive motor 413 is provided on the top of the mounting member 411, and the output end of the first drive motor 413 is fixedly connected to a drive gear 414, which meshes with the rotating ring gear 412.

[0028] Those skilled in the art will appreciate that, by driving the third screw rod 402 to rotate through the output end of the third stepping motor 404, the third movable plate 405 is reciprocated horizontally left and right, thereby driving the mounting member 411 to reciprocate horizontally left and right; by driving the fourth screw rod 406 to rotate through the output end of the fourth stepping motor 408, the lifting member 409 is reciprocated up and down along the fourth guide rod 407, thereby driving the mounting member 411 to reciprocate up and down; by extending or contracting the output end of the fifth electric push rod 410, the mounting member 411 is driven to reciprocate back and forth. Since different chips are tested, different circuit board samples 103 are selected, and the chip mounting positions 104 on different circuit board samples 103 are also different, in summary, the mounting member 411 can move in three directions, horizontally, vertically and vertically, thereby placing the rotating gear ring 412 directly above the chip mounting position 104 on different circuit board samples 103, that is, directly above the chip; secondly, by driving the driving gear through the output end of the first drive motor 413, the driving gear The rotation of wheel 414 causes the rotating ring gear 412 to rotate, driving the bottom frame 415 to rotate. This allows the bottom frame 415 to rotate sequentially to the four sides (front, back, left, and right) of the chip, and the bottom frame 415 can remain parallel to the four sets of side surfaces of the chip. Next, it is known that pins are provided on the bottom of all four sides of the chip, or only on the bottom of two opposing sides. The spacing between the pins is extremely small, usually measured in millimeters. Therefore, in the present invention, a fifth screw rod 416 provided in the bottom frame 415 is provided with millimeter-level high-precision threads. The output end of the fifth stepper motor 418 drives the fifth screw rod 416 to rotate, allowing the mounting frame 419 to reciprocate along the side of the chip, thereby driving the multimeter black pen 420 to reciprocate along the side of the chip. The output end of the second drive motor 421 can change the angle of the multimeter black pen 420. The output end of the fourth stepper motor 408 drives the multimeter black pen 420 downward, thereby allowing the multimeter black pen 420 to contact each set of pins at the bottom of the side of the chip.

[0029] Example 5 Please refer to Figure 8 and Figure 9 As shown, the temperature adjustment mechanism 5 includes a table body 501, which is fixedly installed on the top right side of the body 1. The front and rear sides of the table body 501 are provided with a platform 502. The tops of the two groups of platforms 502 are respectively installed with a first cylinder 503 and a second cylinder 504. The inner walls of the first cylinder 503 and the second cylinder 504 are respectively provided with a heating plate and a condensing plate, and the bottoms of the first cylinder 503 and the second cylinder 504 are both provided with a card slot 505.

[0030] Please refer to Figure 10As shown, the temperature regulating mechanism 5 also includes two groups of fourth fixed blocks 506 fixedly connected to the top of the body 1, and a sixth screw rod 507 is rotatably connected between the two groups of fourth fixed blocks 506.

The two ends of the sixth guide rod 508 are respectively fixedly connected to the inner walls of the two groups of fourth fixed blocks 506, and the outer end of the sixth screw rod 507 is fixedly connected to the output end of the sixth stepping motor 509. The sixth stepping motor 509 is arranged on the outer side wall of one group of fourth fixed blocks 506, and a sixth electric push rod 511 is provided on the top of the fourth movable plate 510, and the output end of the sixth electric push rod 511 is fixedly connected to the third cylinder 512.

[0031] Please refer to Figure 11 As shown, the outer side of the third cylinder 512 is rotatably connected to a threaded rod 513, and the outer side of the third cylinder 512 is fixedly connected to a fixed rod 514. Two groups of movable plates 516 are slidably connected to the fixed rod 514. The threads opened at both ends of the threaded rod 513 have opposite rotation directions, and the two groups of movable plates 516 are respectively threadedly connected to the two ends of the outer surface of the threaded rod 513. A servo motor 515 is provided on the outer wall of the third cylinder 512, and the outer end of the threaded rod 513 is fixedly connected to the output end of the servo motor 515. A card block is welded on the side where the two groups of movable plates 516 are close to each other, and the card block is adapted to the card slot 505.

[0032] It will be understood by those skilled in the art that when performing a temperature test on a chip, the chip needs to be placed in a different temperature environment. The present invention is adapted to set up a first cylinder 503 and a second cylinder 504, and a heating plate and a condensation plate are respectively provided on the inner walls thereof. The first cylinder 503 and the second cylinder 504 can be fixedly installed inside the third cylinder 512 when in use. The material of the third cylinder 512 has heat insulation properties. The output end of the sixth stepping motor 509 drives the sixth lead screw 507 to rotate, so that the fourth movable plate 510 reciprocates back and forth, thereby driving the third cylinder 512 to move to the third cylinder 512 in sequence. Directly above the first cylinder 503 and the second cylinder 504, under the action of the extension of the output end of the sixth electric push rod 511, the third cylinder 512 moves downward, and the first cylinder 503 or the second cylinder 504 can be located inside the third cylinder 512, and then the output end of the servo motor 515 drives the threaded rod 513 to rotate, so that the two groups of movable plates 516 approach each other, driving the two groups of card blocks to be stuck in the card slots 505 opened at the bottom of the first cylinder 503 or the second cylinder 504, thereby fixing the first cylinder 503 or the second cylinder 504 on the third cylinder 512, so that the chip can be heated and cooled respectively.

[0033] In order to clearly describe the working principle of the present invention, we use Figure 1 The perspective is explained as follows: S1. Select a suitable circuit board sample 103 based on the type of chip to be tested, and fix the circuit board sample 103 using the clamping device 102. The robot arm 101 absorbs the chip to be tested produced on the external conveyor and places it on the chip mounting position 104. S2. The first screw rod 202 is driven to rotate by the output end of the first stepper motor 204, so as to drive the pressing plate 209 to reciprocate horizontally and left and right. The extension or contraction of the output end of the first electric push rod 206 drives the pressing plate 209 to reciprocate forward and backward. The extension or contraction of the output end of the second electric push rod 208 drives the pressing plate 209 to reciprocate up and down. Therefore, the pressing plate 209 can move in three directions, horizontally, vertically and vertically, and accurately move to the top of the chip and press it tightly. Since the circuit board sample 103 is connected to the external computer through two wires 105, the computer is in the power-on state and the burning software is opened, and the chip is activated for the first burning. The chip that fails to execute the burning indicates that it itself has a fault. S3. Perform high and low temperature tests on the chips that can be burned. As we all know, some specific chips cannot be burned repeatedly. Therefore, it is necessary to power off the circuit board sample 103. Secondly, the second screw rod 302 is driven to rotate by the output end of the second stepper motor 304, thereby driving the multimeter red pen 310 to move back and forth horizontally; the multimeter red pen 310 is driven to move back and forth by the extension or contraction of the output end of the third electric push rod 306; and the multimeter red pen 310 is driven to move up and down by the extension or contraction of the output end of the fourth electric push rod 308. Therefore, the multimeter red pen 310 can move in three directions, horizontally, vertically, and accurately move to the grounding position of different circuit boards. S4, the robot arm 101 sucks the chip away and places it on the top of the table 501, and drives the sixth screw rod 507 to rotate through the output end of the sixth stepper motor 509, so that the fourth movable plate 510 moves back and forth, and drives the third cylinder 512 to move to the top of the first cylinder 503 and the second cylinder 504 in sequence. Under the action of the extension of the output end of the sixth electric push rod 511, the third cylinder 512 moves downward, and the first cylinder 503 or the second cylinder 504 can be located inside the third cylinder 512 in sequence. The output end of the servo motor 515 drives the threaded rod 513 to rotate, so that the two sets of movable plates 516 approach each other, driving the two sets of card blocks to be clamped into the card slots 505 provided at the bottom of the first cylinder 503 or the second cylinder 504, thereby fixing the first cylinder 503 or the second cylinder 504 on the third cylinder 512, and then the first cylinder 503 or the second cylinder 504 is used to cover the chip on the top of the table 501 in turn, and respectively perform high temperature, then cool, and then heat to room temperature, thereby achieving high and low temperature shock on the chip; S5. The output end of the third stepper motor 404, the output end of the fourth stepper motor 408, and the output end of the fifth electric push rod 410 are used in conjunction with each other to place the rotating ring gear 412 directly above the chip mounting position 104. Then, the robot arm 101 transfers the chip that has been subjected to high and low temperature shock to the chip mounting position 104 and continues to fix it by the pressing plate 209. S6, the fifth stepper motor 418 output end drives the fifth screw rod 416 to rotate, so that the mounting frame 419 can reciprocate on the side of the chip, and the multimeter black pen 420 is driven to reciprocate on the side of the chip. The multimeter black pen 420 can change its angle under the action of the second drive motor 421 output end, and under the action of the fourth stepper motor 408 output end, the multimeter black pen 420 is driven to move downward, so that the multimeter black pen 420 can contact each group of pins at the bottom of the side of the chip, and under the action of the first drive motor 413 output end, the multimeter black pen 420 can be driven to move downward. The bottom frame 415 can be rotated to the four sides of the chip in sequence, and the bottom frame 415 can be kept parallel to the four groups of side surfaces of the chip in sequence, so that the multimeter black pen 420 can contact each group of pins at the bottom of each side of the chip and automatically read the external multimeter reading. If the multimeter reading corresponding to a group of pins at the bottom of a side is different from the multimeter readings corresponding to other groups of pins on the same side, it means that the chip has been damaged by the high and low temperature impact. Otherwise, it is not damaged. The chip has good high and low temperature resistance and excellent resistance. The fully automated operation is convenient and fast, meeting the needs of the staff. S7. It is worth noting that for chips that can be repeatedly burned, the circuit board sample 103 does not need to be powered off and is still connected to the computer and can still be burned. After the high and low temperature shock, whether the chip is damaged under the high and low temperature shock can be determined by whether it can be burned, thereby improving the applicability of the device.
