Description

A PIN pin testing device Technical Field

[0001] This utility model relates to the field of PIN pin detection technology, and specifically to a PIN pin detection device. Background Technology

[0002] PIN inspection is a critical quality control step in the fields of electronics manufacturing, connector production, and repair. It mainly involves a series of inspections and tests on the metal contact pins (PINs) of connectors (such as pin headers, female headers, IC sockets, terminals, etc.) to ensure that they meet design specifications, function properly, and are free of defects.

[0003] Existing technologies, such as the utility model patent with publication number CN222739710U, describe a PIN needle testing device, including a fixed platform with an inverted L-shaped plate fixed on it. A testing component is disposed below the top horizontal plate of the inverted L-shaped plate, and a movable placement component is disposed on the fixed platform. The movable placement component includes a sliding step block disposed on the fixed platform, with multiple fixed sleeves equidistantly fixed on the top surface of the sliding step block, and mounting grooves symmetrically opened on the top of the fixed sleeves. This utility model, through the arrangement of the testing component and the movable placement component, allows the PIN needle to be placed entirely on the fixed sleeves when the sliding step block is located on one side of the fixed platform. When the sliding step block moves to the center of the top surface of the fixed platform, it facilitates the testing component's testing operation. PIN needles of acceptable length are marked upon contact with the sponge block. After testing, the sliding step block moves to the other side of the fixed platform, making it easier to select out unacceptable PIN needles.

[0004] This technical solution marks needles that are longer than the acceptable length, which reduces the accuracy of the detection.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it can be directly set on the other mechanism or there may be an intervening mechanism at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0024] As shown in Figures 1 to 5, the present invention provides a PIN needle testing device, comprising: a base 1, a needle body 4, a rotating mechanism 2 for positioning and moving the needle body 4, and a testing mechanism 3 for testing the needle body 4; by fixing the needle body 4 in the rotating mechanism 2, the needle body 4 can be continuously tested through the operation of the rotating mechanism 2, and the performance and appearance of the needle body 4 can be tested through the testing mechanism 3, thereby improving the accuracy of the test.

[0025] The rotating mechanism 2 includes a motor 21, which is fixedly mounted on the bottom of the base 1. The output shaft of the motor 21 rotates and passes through the base 1, and is fixedly connected to the rotating disk 22, enabling the output shaft of the motor 21 to drive the rotating disk 22 to rotate. A fixing component is circumferentially mounted on the rotating disk 22. Through the rotation of the rotating disk 22, the fixing component is sequentially moved to the position corresponding to the detection mechanism 3, allowing the device to continuously detect the needle body 4. The fixing component includes a positioning seat 23, which is fixedly mounted on the rotating disk 22. The clamping rod 24 and guide rod 25 slide on the inner wall of the seat 23 and pass through it. The clamping rod 24 and guide rod 25 are fixedly connected to the clamping plate 26. The guide rod 25 limits the clamping plate 26 to prevent it from rotating and making it difficult to clamp the needle 4. A spring 27 is sleeved on the clamping rod 24. One end of the spring 27 is fixedly connected to the clamping plate 26, and the other end of the spring 27 is fixedly connected to the inner wall of the positioning seat 23. The spring force of the spring 27 pushes the clamping plate 26 so that the clamping plate 26 can clamp and fix the needle 4.

[0026] It should be added that the top of the clamping plate 26 is provided with a slope, and the slopes on the two clamping plates 26 are close to each other. When the needle body 4 is inserted, the lower end of the needle body 4 contacts the slope, causing the lower end of the needle body 4 to push the two clamping plates 26 to the sides. The clamping plate 26 compresses the spring 27. After the clamping plate 26 clamps the needle body 4, the elastic force provided by the compressed spring 27 enables the clamping plate 26 to clamp the needle body 4 stably, improving the convenience of positioning and fixing the needle body 4.

[0027] The detection mechanism 3 includes: a cylinder 31, which is fixedly mounted on the top of a support frame 34. The piston rod of the cylinder 31 slides through the top of the support frame 34 and is fixedly connected to a detection frame 32. A vertical limiting rod is fixedly connected to the detection frame 32 to limit its movement and prevent it from swaying. A detector 33 is fixedly mounted on the detection frame 32. The piston rod of the cylinder 31 pushes the detection frame 32 down, causing the detector 33 to detect... The probe contacts the needle body 4 to test the performance of the needle body 4 and ensure its normal function. A connecting rod 35 is fixedly connected to the testing frame 32. The connecting rod 35 is fixedly connected to the lifting block 36. The lifting block 36 is slidably mounted on the limiting frame 37, so that the lifting block 36 can only move in the vertical direction. The testing frame 32 drives the lifting block 36 to move up and down on the limiting frame 37 through the connecting rod 35. A mounting frame 38 is fixedly mounted on the lifting block 36, and a testing component is mounted on the mounting frame 38.

[0028] It should be noted that the test piece can be aligned with the fixed piece. During the operation of the rotating mechanism 2, the rotating disk 22 drives the fixed piece to rotate, and the fixed piece can be aligned with the test piece and the detector 33. The rotating disk 22 is driven by the output shaft of the motor 21 to rotate 120°, so that the needle body 4 passes through the feeding, performance testing, appearance testing and unloading in sequence. Each time the rotating disk 22 rotates, there are two fixed pieces that are aligned with the test piece and the detector 33 respectively.

[0029] The testing component includes: a mounting cylinder 39 fixed and passing through the mounting bracket 38, the mounting cylinder 39 being aligned with the needle body 4, a sponge block 391 fixedly mounted in the mounting cylinder 39, the sponge block 391 having a through hole 392, and the sponge block 391 being semi-cylindrical in shape, the two sponge blocks 391 contacting each other, the inner wall of the through hole 392 being divided into two equal parts by the two sponge blocks 391, and pressure sensors 393 being embedded and mounted on the two sponge blocks 391 respectively, the sensing contact surface of the pressure sensor 393 having the same shape as the inner wall of the through hole 392 and being located in the same curved surface, the two pressure sensors 393 being at different heights.

[0030] Furthermore, the diameter of the through hole 392 is smaller than the diameter of the needle body 4. After the needle body 4 is inserted into the through hole 392, the needle body 4 squeezes the sponge block 391, causing the sponge block 391 to deform. The elastic force generated by the deformation of the sponge block 391 pushes the pressure sensor 393 to contact the needle body 4. The length of the needle body 4 is judged by the pressure sensor 393 at different positions.

[0031] It should be noted that the sponge block 391 is divided into three layers, with adjacent layers separated by a separator. The middle layer is thinner, and the middle layer of sponge block 391 is at the same height as the detection head of the detector 33. The detection parts of the two pressure sensors 393 are respectively embedded in the inner walls of the through holes 392 installed on the upper and middle layers of sponge blocks 391. When the lifting block 36 descends, the lifting block 36 drives the mounting frame 38 to descend, and the mounting frame 38 drives the mounting cylinder 39 to descend, so that the needle 4 is inserted into the through hole 392. The needle 4 squeezes the sponge block 391, causing it to deform. The pressure sensor 393 comes into contact with the needle 4 and is pushed by the needle 4. The longer needle 4 comes into contact with two pressure sensors 393 at the same time, while the qualified pressure sensor 393 comes into contact with one. The shorter needle 4 does not come into contact with the pressure sensor 393, which makes it easier to pick out the unqualified needle 4 and determine the reason for the unqualification. No paint is used for marking to prevent paint from dripping onto the fixed platform, which facilitates the processing of unqualified needle 4.

[0032] Working principle:

[0033] The fixing component facilitates the positioning and loading / unloading of the needle body 4. The detector 33 is used to test the performance of the needle body 4, and the length of the needle body 4 is detected by two pressure sensors 393. The number of responses from the pressure sensors 393 can determine whether the length of the needle body 4 is too long, qualified, or too short. The shorter needle body 4 and the longer needle body 4 can be separated. The rotating mechanism 2 continuously feeds individual needle bodies 4 without the need to mark the needle bodies 4, avoiding the use of pigments to mark the needle bodies 4 and the inconvenience of recycling the needle bodies 4. This device improves the accuracy of detection.
