Description

Technical Field

[0001] The utility model relates to the technical field of needle adjusting machines, and more specifically, to a vacuum adsorption component of a needle adjusting machine. Background Art

[0002] The needle adjustment machine adjusts the position of the needle in the PAD according to the MASK. It can be used to adjust the position in the XY direction and the Z direction, as well as the flatness of the needle adjustment table. When adjusting the probe card, some existing needle adjustment machines use vacuum adsorption to fix the probe card. After vacuum adsorption, since the probes on the probe card are distributed at different angles, they need to be switched back and forth during adjustment. It is easy to touch the probes inside the probe card when picking up the adjustment, which may cause the probes that have just been adjusted to be knocked crooked again. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a vacuum adsorption component for a needle adjusting machine, which has the advantage of being rotatable for multi-angle adjustment.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vacuum adsorption assembly of a needle adjusting machine, comprising a workbench, a rotating groove is provided inside the workbench, a rotating ring is rotatably connected inside the rotating groove, an adsorption platform is fixedly installed on the inner side of the rotating ring, an adsorption hole is provided inside the adsorption platform, a connecting shaft is fixedly installed on the bottom of the adsorption platform, a driven gear is fixedly installed on the bottom of the connecting shaft, an exhaust pipe is fixedly installed on the bottom of the adsorption platform, a storage box is sleeved on the outer side of the exhaust pipe, a vacuum pump is fixedly installed on the end of the exhaust pipe away from the adsorption platform, and the vacuum pump is fixedly connected to the workbench.

[0005] As a preferred technical solution of the present invention, a fixing rod is fixedly installed on the bottom of the workbench, a fixing plate is fixedly installed on the bottom of the fixing rod, a motor is fixedly installed on the bottom of the fixing plate, a driving gear is fixedly installed on the output end of the motor, and the outer side of the driving gear is engaged with the driven gear.

[0006] As an optimal technical solution of the present invention, a slide groove is provided inside the workbench, a slider is slidably connected inside the slide groove, a sealing cover is fixedly installed above the slider, an air pump is fixedly installed on the inner side of the sealing cover, a connecting pipe is fixedly installed on the outer side of the air pump, and an air nozzle is fixedly installed on the bottom of the connecting pipe.

[0007] As a preferred technical solution of the present invention, there are four of the air pumps, connecting pipes and air nozzles, and the four air nozzles are all located inside the sealing cover and above the adsorption holes.

[0008] As an optimal technical solution of the present invention, the rotating groove and the rotating ring are both annular, and the rotating ring is located inside the workbench. The interior of the adsorption platform is hollow, and the adsorption platform is at the center of the workbench.

[0009] As a preferred technical solution of the present invention, there are multiple adsorption holes, and the multiple adsorption holes are all located inside the workbench, and the diameters of the multiple adsorption holes are relatively small.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. The utility model fixes a driving gear at the output end of the motor, and the driving gear is meshed with the driven gear. When the probe card needs to be adjusted at multiple angles, the motor is started to drive the driving gear to rotate, so that the driving gear and the driven gear are meshed. At this time, since a connecting shaft is fixed above the driven gear, the connecting shaft is fixedly connected to the adsorption platform, and the adsorption platform is driven by the connecting shaft to rotate through the rotation of the rotating ring and the rotating groove, thereby slightly rotating the adsorption platform, so as to achieve multi-angle adjustment of the probe card, and there is no need to re-fix the probe card and place it again. When moving, the probe will be hit and the need for re-correction will occur.

[0012] 2. The utility model is connected with a slider by sliding inside the slide groove, and a sealing cover is fixedly installed above the slider. At the same time, the sealing cover is located above the adsorption hole. When the adsorption platform has not been used for a long time, a lot of dust may fall into it, which will block the adsorption hole and affect the adsorption effect of the adsorption hole. At this time, the sealing cover is installed above the adsorption hole through the sliding action of the slider and the slide groove, which plays a certain protective role for the adsorption hole. When the probe card needs to be adjusted, the sealing cover needs to be removed by the sliding action of the slider and the slide groove. At this time, the air pump is started to inject air into the air nozzle through the connecting pipe and then discharge it downward through the air nozzle, thereby cleaning the surface above the adsorption platform and achieving the effect that no dust will remain above the adsorption platform before detection.

DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 5 As shown, the utility model provides a vacuum adsorption component of a needle adjusting machine, including a workbench 1, a rotating groove 2 is opened inside the workbench 1, a swivel 3 is rotatably connected inside the rotating groove 2, an adsorption platform 4 is fixedly installed on the inner side of the swivel 3, an adsorption hole 5 is opened inside the adsorption platform 4, a connecting shaft 6 is fixedly installed on the bottom of the adsorption platform 4, a driven gear 7 is fixedly installed on the bottom of the connecting shaft 6, an exhaust pipe 8 is fixedly installed on the bottom of the adsorption platform 4, a storage box 9 is sleeved on the outer side of the exhaust pipe 8, a vacuum pump 10 is fixedly installed on the end of the exhaust pipe 8 away from the adsorption platform 4, and the vacuum pump 10 is fixedly connected to the workbench 1.

[0021] The interior of the storage box 9 is hollow and in the shape of a rectangular parallelepiped, with a reset reel installed inside, with the exhaust pipe 8 wound inside. When the adsorption platform 4 rotates through the rotating ring 3 and the rotating groove 2, the exhaust pipe 8 will be stretched, thereby preventing the exhaust pipe 8 from being insufficient in length. At the same time, when the adsorption platform 4 is reset, the exhaust pipe 8 will be reset inside the storage box 9, making it easy to store and preventing the exhaust pipe 8 from being too long and causing accumulation.

[0022] Among them, a fixing rod 11 is fixedly installed at the bottom of the workbench 1, a fixing plate 12 is fixedly installed at the bottom of the fixing rod 11, a motor 13 is fixedly installed at the bottom of the fixing plate 12, and a driving gear 14 is fixedly installed at the output end of the motor 13, and the outer side of the driving gear 14 is engaged with the driven gear 7.

[0023] The starting motor 13 can drive the driving gear 14 to rotate, so that the driving gear 14 is engaged with the driven gear 7, thereby driving the connecting shaft 6 and the adsorption platform 4 to rotate, thereby achieving the effect of correcting probe cards at different angles.

[0024] Among them, a slide groove 15 is opened inside the workbench 1, and a slider 16 is slidably connected inside the slide groove 15. A sealing cover 17 is fixedly installed above the slider 16. An air pump 18 is fixedly installed on the inner side of the sealing cover 17. A connecting pipe 19 is fixedly installed on the outer side of the air pump 18, and an air nozzle 20 is fixedly installed at the bottom of the connecting pipe 19.

[0025] The sealing cover 17 is circular and hollow inside. At the same time, the sealing cover 17 is located directly above the adsorption hole 5. Its main function is to provide a certain degree of protection for the adsorption hole 5 after being installed through the sliding action of the slider 16 and the slide groove 15, preventing a large amount of dust from entering the interior of the adsorption hole 5 when not in use, thereby causing the adsorption hole 5 to be blocked.

[0026] There are four air pumps 18 , four connecting pipes 19 and four air nozzles 20 . The four air nozzles 20 are all located inside the sealing cover 17 and above the adsorption holes 5 .

[0027] When the probe card needs to be adjusted, the sealing cover 17 needs to be removed through the sliding action of the slider 16 and the slide groove 15. At this time, the air pump 18 is started to inject air into the air nozzle 20 through the connecting tube 19 and then discharge it downward through the air nozzle 20, thereby cleaning the surface above the adsorption platform 4 and ensuring that no dust remains above the adsorption platform 4 before testing.

[0028] The rotating groove 2 and the rotating ring 3 are both annular, and the rotating ring 3 is located inside the workbench 1 . The interior of the adsorption platform 4 is hollow, and the adsorption platform 4 is at the center of the workbench 1 .

[0029] The main function of the swivel 3 is to facilitate the rotation of the adsorption platform 4 by being rotatably connected to the rotating groove 2. At the same time, the swivel 3 has a certain supporting effect on the adsorption platform 4, ensuring the overall stability of the adsorption platform 4.

[0030] There are multiple adsorption holes 5 , all of which are located inside the workbench 1 , and each of the adsorption holes 5 has a relatively small diameter.

[0031] Start the vacuum pump 10 to evacuate the interior of the adsorption platform 4 through the exhaust pipe 8, so that the interior of the adsorption platform 4 is evacuated into a vacuum, and at the same time, a strong suction force is generated inside. At this time, the probe card is placed above the adsorption hole 5 to seal the adsorption hole 5, so that the probe card will be adsorbed above the adsorption hole 5 to achieve a fixed effect.

[0032] The working principle and use process of this utility model:

[0033] First, a slider 16 is slidably connected to the interior of the slide groove 15, and a sealing cover 17 is fixedly installed above the slider 16. At the same time, the sealing cover 17 is located above the adsorption hole 5. When the probe card needs to be adjusted, the sealing cover 17 needs to be removed by the sliding action of the slider 16 and the slide groove 15. At this time, the air pump 18 is started to inject air into the air nozzle 20 through the connecting pipe 19 and then discharge it downward through the air nozzle 20, thereby cleaning the surface above the adsorption platform 4 and ensuring that no dust remains above the adsorption platform 4 before testing.

[0034] Next, after the probe card is placed above the adsorption hole 5, since the outer side of the vacuum pump 10 is fixedly connected to the exhaust pipe 8, and the end of the exhaust pipe 8 away from the vacuum pump 10 is connected to the inside of the adsorption platform 4, the vacuum pump 10 is started to exhaust the inside of the adsorption platform 4 through the exhaust pipe 8, so that the inside of the adsorption platform 4 is evacuated into a vacuum, and a strong suction force is generated inside. At this time, the probe card is placed above the adsorption hole 5 to seal the adsorption hole 5, so that the probe card is adsorbed above the adsorption hole 5, achieving the effect of being fixed;

[0035] Finally, when the probe card needs to be adjusted to different angles, since a driving gear 14 is fixedly installed at the output end of the motor 13, and the driving gear 14 is meshed with the driven gear 7, when the probe card needs to be adjusted at multiple angles, the motor 13 is started to drive the driving gear 14 to rotate, so that the driving gear 14 is meshed with the driven gear 7. At this time, since a connecting shaft 6 is fixed above the driven gear 7, the connecting shaft 6 is fixedly connected to the adsorption platform 4, and the adsorption platform 4 is driven by the connecting shaft 6 to rotate through the rotation of the rotating ring 3 and the rotating groove 2, thereby slightly rotating the adsorption platform 4, so as to achieve multi-angle adjustment of the probe card, and there is no need to fix the probe card again, so as to avoid the probe being knocked crooked and needing to be corrected during movement.
