Description

Technical Field

[0001] This invention relates to the field of semiconductor testing equipment technology, specifically a vibration-type needle pre-assembly device. Background Technology

[0002] Spring probes are important components of semiconductor test sockets, serving as a bridge to provide electrical connections between the chip under test (DUT) and the test equipment. A spring probe consists of a probe tip, a probe tail, a spring, and a probe tube. These four basic components are assembled and pressed together to form the spring probe.

[0003] Currently, automated equipment has not yet penetrated into the niche field of spring probe assembly and pressing, and all work is still done manually. With the maturity of 4G technology and the development of 5G technology, the application of high-frequency, high-speed, small-pitch chips is becoming more and more widespread, and the diameter of the corresponding spring probes is also getting smaller and smaller. The invention patent application No. 202310975673.8, "A Parameter Optimization Method for Pre-assembled Gate Structure of ATE Spring Probes", points out that the diameter of the needle tube is only 0.3mm. This size exceeds the range of normal physiological hand tremors, thus bringing great difficulties to manual alignment and installation, and seriously reducing assembly efficiency. In a single test socket, there are dozens, hundreds, or even thousands of ATE spring probes, making the assembly workload enormous.

[0004] Patent application number 202310663824.6, entitled "A Semi-Automatic Pre-Assembly Device for ATE Spring Probes," discloses a pre-assembly device comprising a feeding turntable and an assembly mechanism. The feeding turntable is equipped with needle tube feeding holes, needle tail feeding holes, spring feeding holes, and needle tip feeding holes. Each of these holes has an upper gate and a lower gate. The assembly mechanism is a cylindrical structure with a main gate at its bottom. This invention enables automatic alignment of the needle tip, spring, and needle tail, and their insertion into the needle tube for pre-assembly, significantly reducing alignment time and improving pre-assembly efficiency. However, because the feeding holes are distributed on the turntable, the assembly efficiency is directly related to the turntable size. Improving assembly efficiency can only be achieved by increasing the turntable diameter, leading to significant modification difficulties and poor compatibility of the device.

[0005] To improve assembly efficiency, the turntable structure needs to be modified. The arrayed needles, needle tails, needle tubes, and springs could be individually housed in four sets of molds. Alignment of each set of needles, needle tails, needle tubes, and springs could be achieved through mold alignment, allowing for the assembly of multiple sets of spring probes at once. However, no relevant existing technical documentation has been found for this concept. Summary of the Invention

[0006] In response to the need for automated assembly of spring probes, and taking into account the structural characteristics of the needle tube, this invention designs a needle tube pre-assembly device, which can realize the automated pre-assembly of needle tubes in batches, providing a technical means for the entire spring probe assembly and pressing, and laying a technical foundation for the rapid assembly of spring probes throughout the entire process.

One end of a connecting spring is fixedly connected to the bottom surface of the bridge-shaped frame. The other end of the connecting spring is fixedly connected to the upper surface of the fixed frame. The connecting spring is in a stretched state.

[0017] The aforementioned vibration-type needle pre-assembly device includes a vibration unit comprising a fixed base, a guide crossbar, a movable seat, a fixed bracket, a rotating disk, a drive motor, a connecting frame, and a movable frame.

[0031] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Method 1

[0033] The following are specific embodiments of the vibration-type needle pre-assembly device of the present invention.

[0034] The vibration-type needle pre-assembly device in this specific embodiment, such as Figure 1 As shown, it includes a pre-assembled substrate 1, a frame fixing unit 2, a vibration unit 3, and an adsorption unit 4;

[0035] The pre-assembled substrate 1 is disposed on the frame fixing unit 2 and is used for pre-assembling the needle tube 9;

[0036] The frame fixing unit 2 is used to clamp and fix the pre-assembled substrate 1 and release it. During the release operation, the needle tubes 9 on the surface of the pre-assembled substrate 1 can be automatically adsorbed and recycled.

[0037] The vibration unit 3 is fixedly connected to the frame fixing unit 2 and is used to drive the frame fixing unit 2 to vibrate;

[0038] The adsorption unit 4 is mounted on the vibration unit 3. When the vibration unit 3 drives the frame fixing unit 2 to vibrate, it automatically draws in and fixes the pre-assembled needle tube 9 in the pre-assembled substrate 1.

[0039] Method 2

[0040] The following are specific embodiments of the vibration-type needle pre-assembly device of the present invention.

[0041] The vibration-type needle pre-assembly device in this specific embodiment, such as Figure 2 and Figure 3 As shown, based on the first specific embodiment, it is further defined that: the pre-assembled substrate 1 includes a pre-assembled plate 6, a groove 7 and a pre-assembled placement hole 8. The groove 7 is provided on the upper surface of the pre-assembled plate 6, and a plurality of pre-assembled placement holes 8 are provided inside the pre-assembled plate 6. The plurality of pre-assembled placement holes 8 are equidistantly arranged inside the pre-assembled plate 6.

[0042] Method 3

[0043] The following are specific embodiments of the vibration-type needle pre-assembly device of the present invention.

[0044] The vibration-type needle pre-assembly device in this specific embodiment, such as Figure 3As shown, based on the second specific embodiment, it is further defined that: the upper end of the pre-assembly placement hole 8 is funnel-shaped, the lower end diameter of the pre-assembly placement hole 8 is in clearance fit with the diameter of the needle tube 9, and the lower end diameter of the pre-assembly placement hole 8 is smaller than the upper end head diameter of the needle tube 9.

[0045] The special structural shape of the pre-assembly placement hole 8 allows the needle tube 9 to be inserted into the pre-assembly placement hole 8 in its normal position. When the needle tube 9 is in the inverted position, due to the large size of the needle tube 9, it cannot enter the pre-assembly placement hole 8, thus causing the needle tube 9 to remain on the surface of the pre-assembly plate 6. In the specific pre-assembly operation, a large number of needle tubes 9 can be placed in the groove 7 at once, and then the vibration of the pre-assembly plate 6 will automatically cause the needle tubes 9 to continuously roll and shake, thereby allowing the needle tubes 9 to be correctly inserted into the pre-assembly placement hole 8, thus realizing the pre-assembly operation.

[0046] Method 4

[0047] The following are specific embodiments of the vibration-type needle pre-assembly device of the present invention.

[0048] The vibration-type needle pre-assembly device in this specific embodiment, such as Figure 4 and Figure 5 As shown, based on the first specific embodiment, the following is further defined: the frame fixing unit 2 includes a fixing frame 10, a placement groove 11, a movable slider 12, a top rod 13, a threaded rod 14, a servo motor 15, a top column 17, a magnet plate 19, and a bridge frame 20; the fixing frame 10 has a placement groove 11 for placing the pre-assembled substrate 1 at its middle position; both sides of the fixing frame 10 have internal cavities; movable sliders 12 are slidably connected to both internal cavities of the fixing frame 10; one end of the top rod 13 is fixedly connected to the side wall of the movable slider 12; the other end of the top rod 13 extends to the placement groove 11; the threaded rod 14 is rotatably connected between the two side walls of the internal cavity of the fixing frame 10; the threaded rod 14 passes through the movable slider 12 and is threadedly engaged with the movable slider 12; a servo motor 15 is fixedly installed on one side of the fixing frame 10; the end of the output shaft of the servo motor 15 is fixedly connected to one end of the threaded rod 14.

[0049] After the pre-assembled substrate 1 is placed in the placement groove 11, the servo motor 15 drives the threaded rod 14 to rotate, thereby driving the movable slider 12 to move, which in turn drives the top rod 13 to move, so that the top rod 13 moves and presses against the side wall of the placement groove 11, thereby fixing the placement groove 11.

[0050] Method 5

[0051] The following are specific embodiments of the vibration-type needle pre-assembly device of the present invention.

[0052] The vibration-type needle pre-assembly device in this specific embodiment, based on specific embodiment four, is further defined as follows: a movable plate 16 is slidably disposed on the upper surface of the fixed frame 10, the movable plate 16 is fixedly connected to the movable slider 12, a top column 17 is fixedly connected to the upper surface of the movable plate 16, a ball bearing 18 is rotatably connected to the top of the top column 17, bridge-shaped frames 20 are fixedly connected to both sides of the magnet plate 19, the bottom surface of the bridge-shaped frames 20 contacts the ball bearing 18, a guide rod 21 is slidably connected to one end of each of the two bridge-shaped frames 20, the bottom end of the guide rod 21 is fixedly connected to the upper surface of the fixed frame 10, one end of a connecting spring 22 is fixedly connected to the bottom surface of the bridge-shaped frame 20, the other end of the connecting spring 22 is fixedly connected to the upper surface of the fixed frame 10, and the connecting spring 22 is in a stretched state.

[0053] When the pre-assembled substrate 1 is fixed, the movement of the sliding block 12 drives the top rod 13 to move, thereby pressing against the side wall of the pre-assembled substrate 1 to fix it. Simultaneously, as the sliding block 12 moves closer to the pre-assembled substrate 1, it also drives the top post 17 to move, causing the ball bearing 18 to move along the bridge frame 20. Since the bridge frame 20 is bridge-shaped, the closer the top post 17 gets to the pre-assembled substrate 1, the more it lifts the bridge frame 20, causing the magnet plate 19 to move upwards and away from the pre-assembled substrate 1. When the pre-assembly is complete and the pre-assembled substrate 1 needs to be removed, the servo motor 15 drives the sliding block 12 to move away from the pre-assembled substrate 1. When the substrate 1 is in motion, the top post 17 on the left moves to the left and the top post 17 on the right moves to the right, causing the ball bearing 18 to move along the bridge frame 20. This causes the magnet plate 19 to descend first, reaching a position above the pre-assembled substrate 1. Since the magnet plate 19 is close to the surface of the pre-assembled substrate 1, it will attract any remaining needle tubes 9 that have not entered the pre-assembly placement hole 8. Then, due to the continuous movement of the top post 17, the bridge frame 20 moves upward, which in turn moves the magnet plate 19 upward, causing the magnet plate 19 to move upward and separate from the pre-assembled substrate 1. This enables the automatic recycling and separation of excess needle tubes 9 on the surface of the pre-assembled substrate 1 without the need for manual recycling, making the processing faster and more convenient.

[0054] Method Six

[0055] The following are specific embodiments of the vibration-type needle pre-assembly device of the present invention.

[0056] The vibration-type needle pre-assembly device in this specific embodiment, such as Figure 6 and Figure 7As shown, based on the first specific embodiment, the vibration unit 3 is further defined as follows: the vibration unit 3 includes a fixed base frame 23, a guide crossbar 24, a movable seat 25, a fixed bracket 26, a rotating disk 27, a drive motor 28, a connecting frame 29, and a movable frame 30; the guide crossbar 24 is fixedly arranged between the two sides of the fixed base frame 23, the movable seat 25 is slidably connected to the guide crossbar 24, the movable seat 25 is fixedly arranged at the bottom surface of the frame fixing unit 2, the fixed bracket 26 is fixedly arranged at the upper surface of the fixed base frame 23, the drive motor 28 is fixedly installed on the side wall of the fixed bracket 26, the rotating disk 27 is fixedly connected to the end of the output shaft of the drive motor 28, one end of the connecting frame 29 is rotatably connected to the side wall of the rotating disk 27, the movable frame 30 is rotatably connected to the other end of the connecting frame 29, and the other end of the movable frame 30 is fixedly connected to the bottom surface of the movable seat 25.

[0057] The drive motor 28 drives the rotating disk 27 to rotate, and then drives the moving frame 30 to reciprocate through the connecting frame 29. This enables the moving seat 25 to drive the pre-assembled substrate 1 to reciprocate through the frame fixing unit 2, which has a vibration effect. This allows the needle tube 9 on the surface of the pre-assembled substrate 1 to fully enter the pre-assembled placement hole 8, thus completing the needle tube 9 placement work.

[0058] Method Seven

[0059] The following are specific embodiments of the vibration-type needle pre-assembly device of the present invention.

[0060] The vibration-type needle pre-assembly device in this specific embodiment, such as Figure 8 and Figure 9 As shown, based on the first specific embodiment, the following is further defined: the adsorption unit 4 includes a fixed cylinder 31, a piston 32, a push rod 33, and a fixed shell 36; two fixed cylinders 31 are provided, and the two fixed cylinders 31 are respectively fixed on both sides of the movable seat 25. The pistons 32 are slidably connected in the inner cavity of the two fixed cylinders 31. One end of the push rod 33 is fixedly connected to the side wall of the piston 32. The other end of the push rod 33 passes through the inner cavity side wall of the fixed cylinder 31 and extends to the outside of the wall. One end of the push rod 33 is fixedly connected to the side wall of the fixed base frame 23. An air intake pipe 34 and an exhaust pipe 35 are connected in the inner cavity of the fixed cylinder 31. An input check valve is installed on the air intake pipe 34, and an output check valve is installed on the exhaust pipe 35.

[0061] When the rotating disk 27 rotates, it drives the movable seat 25 to move back and forth, and at the same time it can drive the fixed cylinder 31 to move.

[0062] Method Eight

[0063] The following are specific embodiments of the vibration-type needle pre-assembly device of the present invention.

[0064] The vibration-type needle pre-assembly device in this specific embodiment is further defined based on the seventh specific embodiment: the fixing shell 36 is fixedly installed on the bottom surface of the frame fixing unit 2 and located directly below the pre-assembly substrate 1. A plurality of suction holes 37 are provided on the upper wall of the inner cavity of the fixing shell 36. The suction holes 37 correspond one-to-one with the bottom end of the pre-assembly placement hole 8. One end of the suction pipe 34 extends into the inner cavity of the fixing shell 36 and is fixedly connected to the fixing shell 36.

[0065] When the movable seat 25 reciprocates, it drives the fixed cylinder 31 to move left and right. When the movable seat 25 moves to the left, it drives the right fixed cylinder 31 to move to the left, causing the piston 32 to move to the right in the inner cavity of the right fixed cylinder 31, and drawing air from the inner cavity of the fixed shell 36 through the suction pipe 34. When the movable seat 25 moves to the right, it drives the left fixed cylinder 31 to move to the right, causing the piston 32 to move to the left in the inner cavity of the left fixed cylinder 31, and drawing air from the inner cavity of the fixed shell 36 through the suction pipe 34. That is, when the fixed cylinder 31 moves left and right, the suction hole 37 can draw air from the bottom side of the pre-assembly placement hole 8, so that the needle tube 9 is drawn in and fixed, preventing the needle tube 9 inside the pre-assembly placement hole 8 from loosening during the vibration of the pre-assembly substrate 1.

[0066] Method Nine

[0067] The following are specific embodiments of the vibration-type needle pre-assembly of the present invention.

[0068] The vibration-type needle pre-assembly method according to this specific embodiment includes the following steps:

[0069] Step a: Preparation

[0070] The servo motor 15 controls the moving slider 12 to drive the top rod 13 to move and press against the side wall of the pre-assembled substrate 1 to fix the pre-assembled substrate 1. At the same time, when the moving slider 12 moves towards the pre-assembled substrate 1, it drives the top column 17 to move, thereby causing the ball 18 to move away from the guide rod 21 along the bridge frame 20. Using the arch shape of the bridge frame 20, the bridge frame 20 is lifted up, causing the magnet plate 19 to move upward and away from the pre-assembled substrate 1.

[0071] Step b, Placement of work

[0072] Place the needle 9 on the pre-assembly plate 6 of the pre-assembly substrate 1;

[0073] Step c, vibration pre-installation

[0074] The drive motor 28 drives the rotating disk 27 to rotate, and then drives the moving frame 30 to reciprocate through the connecting frame 29. This enables the moving seat 25 to drive the pre-assembled substrate 1 to reciprocate through the frame fixing unit 2, which has a vibration effect, so that the needle tube 9 on the surface of the pre-assembled substrate 1 can fully enter the pre-assembled placement hole 8, and complete the needle tube 9 placement work.

[0075] Step d: Adsorption and recovery

[0076] Servo motor 15 controls the moving slider 12 to move towards guide rod 21, thereby moving it away from the pre-assembled substrate 1. At the same time, the moving slider 12 drives the top column 17 to move towards guide rod 21, which in turn causes the ball bearing 18 to move along the bridge frame 20 towards guide rod 21. Utilizing the arch shape of the bridge frame 20, the magnet plate 19 first descends to above the pre-assembled substrate 1, adsorbing the needle tubes 9 on the surface of the pre-assembled substrate 1 that have not entered the pre-assembled placement hole 8. The top column 17 continues to move, and the magnet plate 19 rises again, separating from the pre-assembled substrate 1, thereby realizing the automatic recycling of excess needle tubes 9 on the surface of the pre-assembled substrate 1.

[0077] Method 10

[0078] The following are specific embodiments of the vibration-type needle pre-assembly of the present invention.

[0079] The vibration-type needle pre-assembly method under this specific embodiment, based on specific embodiment nine, is further defined as follows: In step c, when the moving seat 25 reciprocates, it drives the fixed cylinder 31 to move left and right. When the moving seat 25 moves to the left, it drives the right fixed cylinder 31 to move to the left, so that the piston 32 moves to the right in the inner cavity of the right fixed cylinder 31 and draws air from the inner cavity of the fixed shell 36 through the suction pipe 34; when the moving seat 25 moves to the right, it drives the left fixed cylinder 31 to move to the right, so that the piston 32 moves to the left in the inner cavity of the left fixed cylinder 31 and draws air from the inner cavity of the fixed shell 36 through the suction pipe 34; that is, when the fixed cylinder 31 moves left and right, the suction hole 37 can draw air from the bottom side of the pre-assembly placement hole 8, so that the needle 9 is drawn in and fixed, and the needle 9 inside the pre-assembly placement hole 8 is prevented from loosening during the vibration of the pre-assembly substrate 1.
