Description

Technical Field

[0001] This solution relates to the field of micro probe assembly and processing technology, and in particular to a probe assembly pressure needle device. Background Technology

[0002] With the continuous development of semiconductor chip packaging structures and technologies, the size and spacing of some chip pins and contacts are becoming increasingly smaller. This places increasingly higher demands on the structure and precision of chip packaging test connector probes, with some wafer-level packaged chip test probes having diameters as small as 0.05mm. In some applications, to reduce the path length of connector channels and thus lower channel resistance and signal loss, shorter connector spring probes need to be designed for matching; this poses a significant challenge to the manufacturing and assembly processes of spring probes.

[0003] The current design of spring probes generally has at least four components: the probe barrel, the micro-precision spring, and two piston pins at the top and bottom.

[0004] Spring probe assembly process: 1. With the help of auxiliary fixtures, the four parts are assembled together and placed in the semi-finished product transition plate; 2. The pre-assembled semi-finished product is clamped into the machine for stamping or riveting into the finished product. During the operation of placing it into the machine, because the pre-assembled semi-finished parts are very small and have not been stamped or riveted to constrain and fix them, they are easy to separate and fall apart, and the stamping and riveting process of the finished product is prone to producing defective products.

[0005] Existing assembly equipment solutions require manual correction and positioning of the needles. However, human hands are prone to trembling, which not only fails to prevent the separation and scattering of semi-finished products, resulting in defective products, but also consumes time and effort and is inefficient.

[0006] Therefore, there is a need for a needle pressing device that can increase the yield and improve production efficiency through automation. Summary of the Invention

[0007] To address the aforementioned issues, this solution provides a probe assembly pin device that can increase the yield rate and improve probe assembly efficiency through automation.

[0015] Furthermore, the moving end of the second micrometer is connected to and drives the second slider to slide on the first slider;

[0016] The second limiting rod at the other end of the second slider is slidably connected to the second limiting plate on the fixed plate, and the tension of the second limiting rod is adjusted to lock the second slider.

[0017] Furthermore, a connecting block for the flipping module is fixed at the top of the second slider, the connecting block is rotatably connected to the connecting frame, and an electric cylinder is fixed at the other end of the connecting frame.

[0018] Furthermore, the power end of the electric cylinder is connected to the pressure regulating module via the first connecting plate, the pressure regulating module is connected to the fixing frame, and the fixing frame limits the pressure needle in the middle.

[0019] Furthermore, the pressure adjustment module includes a third micrometer and a third limiting plate fixed on both sides of the second connecting plate, and the second connecting plate includes a first slide rail and a second slide rail.

[0020] Furthermore, the first slide rail is slidably connected to the third slider, the second slide rail is slidably connected to the fourth slider, and a spring assembly is fixed between the third slider and the fourth slider.

[0021] Furthermore, the third slider has a side limiting block connected to the moving end of the third micrometer, and the other side third limiting rod slides within the third limiting plate.

[0023] Furthermore, the pressure needle has an adsorption function, the top of the needle shell is connected to an air passage, and an elastic element and a needle are slidably connected in the internal cavity of the needle shell. One end of the needle contacts the elastic element, and the other end is limited in the needle outlet of the shell.

[0041] The present solution will be further described below with reference to the accompanying drawings and embodiments:

[0042] Example 1:

[0043] A probe assembly press needle device, such as Figure 1-10 As shown, the bracket 1 fixes the adjustment assembly 100 and connects the pressure needle assembly 200.

[0044] The adjustment component 100 includes a displacement module 110 and a flipping module 120, which can drive the pressure needle assembly 200 to move along the X-axis, Y-axis and axial direction.

[0045] The displacement module 110 has a fixing plate 111 fixed to the top of the bracket 1. A first micrometer 112 and a second micrometer 113 are fixed to one adjacent side of the fixing plate 111, which are used to adjust the position of the X-axis and Y-axis, respectively. The opposite side of the first micrometer 112 is connected to a first limiting rod 114, and the opposite side of the second micrometer 113 is fixed to a second limiting plate 115.

[0046] The moving end of the first micrometer 112 is connected to and drives the first slider 116 to slide on the fixed plate 111. The first limiting plate 117 and the first limiting rod 114 at the other end of the first slider 116 are slidably connected. The adjusted first slider 116 is locked by adjusting the tightness of the first limiting rod 114.

[0047] The moving end of the second micrometer 113 is connected to and drives the second slider 118 to slide on the first slider 116. The second limiting rod 119 and the second limiting plate 115 at the other end of the second slider 118 are slidably connected. The adjusted second slider 118 is locked by adjusting the tightness of the second limiting rod 119.

[0048] In this embodiment, the first micrometer 112 is defined to drive the first slider 116 to move along the X-axis. Then, under the relative position, the second micrometer 113 drives the second slider 118 to move along the Y-axis.

[0049] Specifically, when the position of the X-axis needs to be adjusted, the first micrometer 112 drives the first slider 116 to move along the X-axis on the fixed plate 111. After moving to the accurate position, the first limit rod 114 is rotated to lock the position of the first limit plate 117 and the fixed plate 111.

[0050] When the position of the Y-axis needs to be adjusted, the second micrometer 113 drives the second slider 118 to move along the Y-axis on the first slider 116. After moving to the accurate position, the second limit rod 119 is rotated to lock the position of the second limit plate 115 and the first slider 116.

[0051] The top of the second slider 118 is fixed with a flip module 120. The flip module 120 is used to observe the condition of the mounting platform when changing the probe model. One end of the connecting bracket 121 is rotatably connected to the connecting block 122, and the other end is fixed with the pressure needle assembly 200. The connecting block 122 is fixed on the second slider 118.

[0052] The pressure needle assembly 200 is used to straighten and limit the probe and press down, and includes an electric cylinder 210, a pressure adjustment module 220 and a pressure needle head 230.

[0053] The electric cylinder 210 controls the up-and-down movement of the pressure needle 230 and is fixed on the connecting frame 121. The power end is connected to the pressure regulating module 220 through the first connecting plate 201.

[0054] The pressure adjustment module 220 is used to control the downward pressure to prevent excessive pressure from damaging the probe. It includes a second connecting plate 221 connected to a first connecting plate 201. A third micrometer 222 and a third limiting plate 223 are respectively fixed to both sides of the second connecting plate 221. The second connecting plate 221 includes a first slide rail 2231 and a second slide rail 2232. The first slide rail 2231 is slidably connected to a third slider 224, and the second slide rail 2232 is slidably connected to a fourth slider 225. A spring assembly 226 is fixed between the third slider 224 and the fourth slider 225.

[0055] The third slider 224 has a side limiting block 2241 connected to the moving end of the third micrometer 222, and a third limiting rod 2242 on the other side sliding within the third limiting plate 223. Adjusting the third micrometer 222 changes the position of the third slider 224, further stretching or compressing the spring in the spring assembly 226, thereby adjusting the downward pressure of the pressure needle 230. Adjusting the tension of the third limiting rod 2242 locks the adjusted third slider 224 in place.

[0056] The fourth slider 225 is connected to a fixing frame 227 at its bottom. The fixing frame 227 limits the pressure needle head 230 in the middle. In the structural design of this solution, the assembly of different types of probes can be completed by adjusting the model of the pressure needle head 230, which can adapt to different fixed probe models and is more flexible.

[0057] The pressure needle 230 has an adsorption function. The top of the needle shell 231 is connected to the air passage. The elastic element 232 and the needle 233 are limited and slidably connected in the internal cavity of the needle shell 231. One end of the needle contacts the elastic element 232, and the other end is limited in the needle outlet 2301 of the shell.

[0058] In this embodiment, the elastic element 232 is a spring, and the elastic element 232 and the spring assembly 226 provide double buffering force for the needle tip 233 to avoid excessive force on the probe during positioning and pressing, which would cause damage.

[0059] The needle 233 is hollow inside. When the air passage at the top of the needle shell 231 is vacuumed, the tip of the needle 233 adsorbs the top of the probe. There is no need for manual continuous straightening and positioning, which avoids the loss caused by shaking and improves production efficiency.

[0060] Further explanation based on its usage mechanism:

[0061] S1, Positioning

[0062] Place the probe and adjust the position of the pressure needle 230.

[0063] When the position of the X-axis needs to be adjusted, the first micrometer 112 drives the first slider 116 to move along the X-axis on the fixed plate 111. After moving to the accurate position, the first limit rod 114 is rotated to lock the position of the first limit plate 117 and the fixed plate 111.

[0064] When the position of the Y-axis needs to be adjusted, the second micrometer 113 drives the second slider 118 to move along the Y-axis on the first slider 116. After moving to the accurate position, the second limit rod 119 is rotated to lock the position of the second limit plate 115 and the first slider 116.

[0065] After the position is adjusted, the electric cylinder 210 controls the pressure needle 230 to descend for the first time. After the first stroke of the electric cylinder 210 is completed, the needle tip 233 of the pressure needle 230 adsorbs the top of the probe, and the probe is straightened and limited.

[0066] S2, Pressing needle

[0067] The electric cylinder 210 controls the needle head 230 to descend for the second time. After the electric cylinder 210 completes its second stroke, the needle head 233 of the needle head 230 presses the probe downward, completing the needle pressing and dotting work with the cooperation of other units.

[0068] In summary, the needle pressing assembly and adjustment assembly provided in this application do not require continuous manual alignment and limit positioning, thus avoiding losses caused by shaking. Automation increases the yield and improves production efficiency.

[0069] The spring assembly and pressure needle provided in this application both include springs to provide double buffering force for the needle, avoiding excessive force on the probe during positioning and pressure needle operation, which could cause damage.
