Depending on the situation, there will also be a demand for electronic components, reinforcement plates, etc. It is mainly used to test bare cores. The probe card adjustment needle is difficult to adjust because the internal needle tip is very long and thin. When testing bare cores, it is easy to be bumped and cause the needle to become crooked. Therefore, an adjustment machine is needed to adjust the probe card needle. However, existing needle adjustment machines are difficult to adjust probe cards of different sizes, and the needle is prone to shaking during adjustment, which can easily lead to adjustment failure.

[0019] The following will be combined with the 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 needle adjustment machine device for adjusting the needle of a probe card, including a workbench 1, a slide groove 2 is opened inside the workbench 1, a slider 3 is movably connected inside the slide groove 2, a clamping rod 4 is fixedly installed above the slider 3, a stabilizing plate 5 is fixedly installed on the side of the clamping rod 4 close to the center point of the workbench 1, a silicone pad 6 is fixedly installed above the stabilizing plate 5, a fixing plate 7 is fixedly installed above the workbench 1, a motor 8 is fixedly installed on the right side of the fixing plate 7, a screw 9 is fixedly installed on the output end of the motor 8, the screw 9 is meshed with the clamping rod 4, a limiting sleeve 10 is sleeved on the outer side of the screw 9, and the limiting sleeve 10 is fixedly connected to the clamping rod 4.

[0021] The clamping rod 4 is displaced above the workbench 1 by the sliding action of the slider 3 and the slide groove 2. When facing probe cards of different sizes, the distance between the clamping rod 4 and the center point of the workbench 1 can be adjusted to facilitate the clamping of probe cards of different sizes. At the same time, the probe card is placed above the stabilizing plate 5 to ensure a certain stability of the probe card when correcting the needle adjustment.

[0022] A bottom plate 11 is fixedly mounted on the rear of the workbench 1 , a support rod 12 is fixedly mounted above the bottom plate 11 , a connecting plate 13 is fixedly mounted above the support rod 12 , and a mounting groove 14 is provided inside the connecting plate 13 .

[0023] The main function of the connecting plate 13 is to provide certain support and connection effects for the microscope 17. At the same time, there are two mounting grooves 14, both of which are located above the workbench 1. The main function is to facilitate the installation of the microscope 17 through the sliding connection with the slider 15.

[0024] Among them, the interior of the mounting groove 14 is slidably connected to a slider 2 15, a connecting block 16 is fixedly installed in front of the slider 2 15, a microscope 17 is fixedly installed above the connecting block 16, an observation hole 18 is fixedly installed in front of the microscope 17, and an observation tube 19 is fixedly installed at the bottom of the microscope 17.

[0025] The observation tube 19 is located just above the center point of the workbench 1. Its main function is to observe the probe card above the workbench 1 through the observation hole 18 by adjusting the magnification. Since the needle inside the probe card is relatively thin, it is easy to observe and correct.

[0026] Among them, a fixed block 20 is fixedly installed at the rear of the microscope 17, a telescopic rod 21 is movably connected to the inside of the connecting plate 13, a spring 22 is sleeved on the outside of the telescopic rod 21, a limit block 23 is fixedly installed above the spring 22, and a pin 24 is inserted into the inside of the limit block 23, and the pin 24 passes through the inside of the fixed block 20.

[0027] The main function of the latch 24 is to pass through the interior of the limit block 23 and the fixing block 20, thereby limiting and fixing the microscope 17 to prevent the microscope 17 from sliding downward due to gravity. At the same time, the telescopic rod 21 always provides elastic force upward, which can keep the height of the limit block 23 adjustable, thereby achieving the effect of adjusting the height of the microscope 17, and facilitating the observation hole 18 to provide a comfortable height for people of different heights to observe.

[0028] Among them, the screw 9 is located above the workbench 1, and the threads on the surface of the screw 9 are distributed in relative directions to the left and right sides from the center point of the workbench 1. There are two clamping rods 4, and the two clamping rods 4 are respectively located on the left and right sides of the middle of the screw 9.

[0029] After the motor 8 is started to drive the lead screw 9 to rotate, the lead screw 9 will engage with the clamping rod 4, so that the clamping rod 4 is displaced through the sliding action of the slider 3 and the slide groove 2, thereby achieving the effect of clamping probe cards of different widths and lengths.

[0030] Among them, there are four slide grooves 2 and four sliders 3, and the four slide grooves 2 and four sliders 3 are all located on the left and right sides of the center point of the workbench 1. There are two stabilizing plates 5 and two silicone pads 6. The two silicone pads 6 are perpendicular to the two stabilizing plates 5 respectively, and the material of the two silicone pads 6 is relatively soft.

[0031] The main function of the four slide grooves 2 and the four sliders 3 is to ensure a certain stability when the two clamping rods 4 are engaged with the screw 9. At the same time, since the material of the two silicone pads 6 is relatively soft, it is convenient to protect the probe card when clamping to prevent the surface of the probe card from being damaged.

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

[0033] First, install the microscope 17 in front of the connecting plate 13 by sliding the slider 15 and the mounting slot 14. After adjusting the height, insert the pin 24 into the inner part of the limit block 23 and the fixed block 20 respectively, so that the limit block 23 and the fixed block 20 are fixed at the same time, thereby fixing the microscope 17. Then, adjust the magnification of the internal lens through the observation tube 19 to achieve the effect of convenient observation.

[0034] Secondly, since a slider 1 3 is slidably connected inside the slide groove 2, a clamping rod 4 is fixedly installed above the slider 1 3, and a lead screw 9 is engaged with the rear of the clamping rod 4, and the threads opened on the lead screw 9 are distributed in opposite directions, when it is necessary to clamp probe cards of different widths and lengths, the motor 8 is started to drive the lead screw 9 to rotate, so that the lead screw 9 is engaged with the clamping rod 4, thereby adjusting the distance between the clamping rod 4 and the center point of the workbench 1. After the clamping rod 4 is adjusted to a suitable distance, the probe card is placed above the stabilizing plate 5, and the motor 8 is restarted to make the lead screw 9 continue to engage with the clamping rod 4, so that the probe card contacts the silicone pad 6, thereby achieving the effect of clamping the probe card and keeping it stable.

[0035] Finally, since the probe card is in contact with the silicone pad 6 when clamping, and the material of the silicone pad 6 is relatively soft, it has a protective effect on the probe card to a certain extent, preventing scratches on the surface during the clamping process.
