It can be understood that the first connecting member 110 can be a first bolt, which is threadedly connected to the inner wall of the first threaded hole 120 and penetrates the first guide hole 211. By tightening the first bolt, the nut of the first bolt can be pressed against the first mounting portion 210, thereby enabling the first mounting portion 210 to be fixed to the support base 100. When the first mounting portion 210 and the second mounting portion 220 need to be rotated or moved, the first bolt only needs to be loosened, and the nut of the first bolt is separated from the abutment with the first mounting portion 210. At this time, the first mounting portion 210 and the second mounting portion 220 can be rotated or moved, and the relative position between the first mounting portion 210 and the second mounting portion 220 and the support base 100 is changed, thereby changing the relative position between the ink dot assembly 300 and the support base 100, so that the ink dot assembly 300 can change its position according to the specific structure of the probe machine, which is conducive to improving the applicability of the ink dot marking device.

It can be understood that the inner wall of the second slide groove has a limiting effect on the third mounting portion 230, so that the third mounting portion 230 can accurately move along the up-down direction.

[0050] refer to Figure 2The transmission assembly 600 includes a first transmission rod 610, a second transmission rod 620, a third transmission rod 630, a first tooth plate 640, a second tooth plate 650, a first gear 660, a second gear 670, a third gear 680, a fourth gear 690, a first rotating shaft 661 and a second rotating shaft 681. A second guide hole 223 parallel to the up-down direction is opened on the second mounting portion 220. One end of the first transmission rod 610 is connected to the output end of the lifting drive assembly 500, and the other end of the first transmission rod 610 is connected to the upper end of the ink dot part 310. The second transmission rod 620 is penetrated in the second guide hole 223. The upper end of the second transmission rod 620 is connected to the first transmission rod 610, and the lower end of the second transmission rod 620 is connected to the first tooth plate 640. The upper end of the third transmission rod 630 can be slidably connected to the third mounting portion 230 along the up-down direction. The lower end of the third transmission rod 630 is connected to the second tooth plate 650, and the lower end of the second tooth plate 650 is connected to the sleeve 400. The first rotating shaft 661 and the second rotating shaft 681 are both parallel to the front-to-back direction. The first rotating shaft 661 and the second rotating shaft 681 can be rotatably connected to the third mounting portion 230. The two ends of the first rotating shaft 661 are respectively connected to the first gear 660 and the second gear 670, and the two ends of the second rotating shaft 681 are respectively connected to the third gear 680 and the fourth gear 690. The first gear 660 is meshed with the first tooth plate 640, the second gear 670 is meshed with the third gear 680, and the fourth gear 690 is meshed with the second tooth plate 650. The lifting drive assembly 500 is used to drive the first transmission rod 610 to rise or fall, so as to rise the ink dot part 310 and lower the sleeve 400, or to lower the ink dot part 310 and rise the sleeve 400.

[0051] It can be understood that the lifting drive assembly 500 drives the first transmission rod 610 to rise, the first transmission rod 610 drives the ink dot element 310 and the second transmission rod 620 to rise, and the first tooth plate 640 on the lower end of the second transmission rod 620 rises together with the second transmission rod 620. Since the first tooth plate 640 is meshed with the first gear 660, the first gear 660, the first rotating shaft 661 and the second gear 670 can rotate. Since the second gear 670 is meshed with the third gear 680, the third gear 680, the second rotating shaft 681 and the fourth gear 690 can rotate, and the third gear 680 and the second gear 670 rotate in opposite directions. Since the fourth gear 690 is meshed with the second tooth plate 650, the third transmission rod 630 and the sleeve can be lowered, so that the lower end of the ink dot element 310 can extend into the sleeve 400 and abut against the adsorption medium.

[0052] The lifting drive assembly 500 drives the first transmission rod 610 to descend, and the first transmission rod 610 drives the ink dotting member 310 and the second transmission rod 620 to descend, and the first tooth plate 640 on the lower end of the second transmission rod 620 descends along with the second transmission rod 620. Since the first tooth plate 640 is meshed with the first gear 660, the first gear 660, the first rotating shaft 661 and the second gear 670 can rotate. Since the second gear 670 is meshed with the third gear 680, the third gear 680, the second rotating shaft 681 and the fourth gear 690 can rotate, and the third gear 680 rotates in the opposite direction to the second gear 670. Since the fourth gear 690 is meshed with the second tooth plate 650, the third transmission rod 630 and the sleeve can rise, so that the lower end of the ink dotting member 310 can extend out of the sleeve 400 and abut against the chip to achieve ink dotting. It is not difficult to understand that in the sampling device of the present invention, during the process of the ink dotting member 310 marking ink, the adsorption medium will not absorb the ink on the ink dotting head. When the ink dotting member 310 is in the process of rising and resetting, the adsorption medium can absorb the ink remaining on the lower end of the ink dotting member 310, thereby avoiding the ink remaining on the lower end of the ink dotting member 310 from splashing onto other chips, thereby avoiding misjudgment of the detection results of other chips.

[0053] refer to Figure 2 , the lifting drive assembly 500 includes an electromagnet linear drive member and an elastic member, the output shaft of the electromagnet linear drive member is connected to the first transmission rod 610, one end of the elastic member is connected to the first transmission rod 610, and the other end of the elastic member is connected to the cylinder body of the electromagnet linear drive member, and the elastic member is used to push the first transmission rod 610 upward. When the electromagnet linear drive member is powered on, the output shaft of the electromagnet linear drive member drives the first transmission rod 610 to descend. When the electromagnet linear drive member is powered off, the elastic member drives the first transmission rod 610 and the output shaft of the electromagnet linear drive member to rise. It can be understood that when the electromagnet linear drive member is powered on, the output shaft of the electromagnet linear drive member is magnetically attracted to descend, thereby causing the first transmission rod 610 to descend. When the electromagnet linear drive member is powered off, the output shaft of the electromagnet linear drive member loses the magnetic force it receives, and at this time, under the elastic force of the elastic member, the first transmission rod 610 rises. The elastic member can be a spring, and the spring is sleeved on the output shaft of the electromagnet linear drive member.

[0054] As an embodiment of the present invention, the adsorption medium is a sponge, which can absorb the ink remaining on the lower end of the ink-dispensing member 310. The adsorption medium can also be a cloth.
