Description

Technical Field

[0001] This utility model relates to the field of diodes, and in particular to a diode damage detection device. Background Technology

[0002] In the semiconductor device manufacturing industry, diodes, as fundamental electronic components, require rigorous quality inspection to ensure the reliability of electronic products. During the manufacturing process, diodes are susceptible to damage or even breakage of their leads due to static electricity, mechanical stress, or process defects. Traditional testing methods often rely on manual contact testing, which suffers from low efficiency and missed detections. While some automated testing equipment can improve efficiency, they generally suffer from complex structures, high maintenance costs, and poor compatibility with different diode specifications, making it difficult to meet the demands of modern electronic manufacturing for high-precision and highly flexible testing. Utility Model Content

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] This utility model provides a diode damage detection device, including an insulating track and a support frame. The support frame includes a bottom section disposed on one side of the insulating track, a vertical section disposed on the top surface of the bottom section, a horizontal section disposed on the side of the vertical section facing the insulating track, a downward feeding cylinder disposed at the lower part of the horizontal section, a mounting bracket disposed at the bottom of the output shaft of the cylinder in the same direction as the insulating track, probe brackets disposed at both ends of the mounting bracket, and multiple probes disposed on the probe brackets.

[0005] Furthermore, the insulating track has a through slot running vertically through it, and an optical fiber sensor is installed inside the slot. The optical fiber sensor is located at the wire of the diode.

[0006] Furthermore, a throttle valve is provided at the air inlet and outlet of the cylinder to control the air inlet and outlet speed of the cylinder.

[0007] Furthermore, a right-angled triangular reinforcing rib is provided at the corner where the vertical segment and the horizontal segment connect.

[0008] Furthermore, the surface of the mounting bracket is provided with laser-etched scale markings along its length, and the tips of the scale markings are engraved with marking lines.

[0009] Furthermore, the probe holder has multiple circular through holes arranged at intervals along the vertical direction, and a nut is provided in the middle of the probe to lock and fix the probe to the probe holder.

[0010] The beneficial effects of this utility model are as follows:

[0011] The piston speed in a cylinder depends on the flow rate of compressed air entering or exiting the cylinder. Installing a throttle valve at the intake port limits the airflow into the cylinder, thus reducing the cylinder's extension speed. Similarly, installing a throttle valve at the exhaust port limits the airflow out of the cylinder, thus reducing the cylinder's retraction speed. By adjusting the throttle valve opening, the cylinder's speed can be easily and steplessly adjusted to suit different operating requirements.

[0012] When the piston approaches the end of its stroke, the piston rod blocks the main exhaust passage on the cylinder barrel, forcing the remaining air to be discharged only through the exhaust port equipped with a throttle valve.

[0013] Because the throttle valve limits the exhaust speed, the remaining air in the cylinder chamber is compressed, which generates reverse pressure on the piston, causing its movement speed to slow down significantly at the end of the stroke, thereby greatly reducing or eliminating the impact.

[0014] Properly adjusting the throttle valve can make the cylinder start and stop more smoothly and without impact, avoiding load swaying or inaccurate positioning caused by sudden speed changes.

[0015] By limiting unnecessary rapid movements, the instantaneous consumption of compressed air can be reduced. Avoiding high-speed impacts and precise speed control can sometimes reduce the total air consumption over the entire cycle. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings.

[0020] This invention provides a diode damage detection device, comprising an insulating track 1 and a support frame 2. The support frame 2 includes a bottom section 201 disposed on one side of the insulating track 1, a vertical section 202 disposed on the top surface of the bottom section 201, and a horizontal section 203 disposed on the side of the vertical section 202 facing the insulating track 1. A downward-feeding cylinder 3 is disposed at the lower part of the horizontal section 203. A mounting bracket 4, co-oriented with the insulating track 1, is disposed at the bottom of the output shaft of the cylinder 3. Probe supports 5 are disposed at both ends of the mounting bracket 4, and multiple probes 6 are disposed on the probe supports 5. The support frame 2 forms a stable three-dimensional support structure through the combination of the bottom section 201, the vertical section 202, and the horizontal section 203. The bottom section 201 is fixed to one side of the insulating track 1 to provide basic support, the vertical section 202 adjusts the vertical height and orientation of the probe supports 5, and the horizontal section 203 ensures the horizontal alignment accuracy of the probes 6, enabling the probes 6 to be vertically aligned with the diode pins on the insulating track 1.

[0021] The insulating track 1 has a through slot 101 extending vertically. An optical fiber sensor 102 is installed within the slot 101, located at the diode's conductor. The optical fiber sensor 102 is close to the diode conductor surface and detects whether the conductor is broken or damaged by changes in the optical signal transmitted through the optical fiber. The lateral position of the slot 101 on the insulating track 1 is adjusted to match the detection point orientation of diode conductors of different specifications, ensuring that the sensor 102 always covers the critical detection area of ​​the conductor.

[0022] A throttle valve 301 is installed at the air inlet and outlet of the cylinder 3 to control the air intake and exhaust speed of the cylinder 3. The throttle valve 301 regulates the movement speed of the cylinder 3 by limiting the intake and exhaust flow of compressed air: the intake throttle controls the descent speed of the probe 6 to avoid rapid impact damage to the diode; the exhaust throttle controls the ascent speed of the probe 6 to prevent the probe 6 from affecting the detection stability due to inertial sway when it is disengaged, thereby accurately adjusting the vertical movement orientation and contact force of the probe 6.

[0023] A right-angled triangular reinforcing rib 204 is provided at the corner where the vertical section 202 and the horizontal section 203 connect. The right-angled triangular reinforcing rib 204, through its geometric stability, distributes the weight of the cylinder 3 borne by the horizontal section 203 and the reaction force of the probe 6 during detection, preventing the horizontal section 203 from deforming under force and causing the probe 6 to shift horizontally, ensuring that the probe 6 is always vertically aligned with the center of the diode pin on the insulating track 1.

[0024] The mounting bracket 4 has laser-etched scale markers 401 along its length. Each scale marker 401 has a marking line 402 engraved at its tip. The laser-etched scale markers 401 provide a high-precision length direction reference, while the marking line 402 serves as a zero-point marker, helping operators quickly locate the probe holders 5 on the mounting bracket 4. The scale allows for fine-tuning of the distance between the two probe holders 5, accommodating the pin spacing of diodes of different lengths and adjusting the horizontal distribution of the probes 6.

[0025] The probe holder 5 has multiple circular through holes 501 arranged vertically at intervals. A nut 502 is provided in the middle of the probe 6, which locks the probe 6 onto the probe holder 5. The multiple circular through holes 501 allow the probe 6 to be installed at different vertical heights. By selecting different positions of the through holes 501, the contact height between the tip of the probe 6 and the diode pin can be adjusted. After the nut 502 is tightened, the vertical orientation of the probe 6 is fixed, ensuring that the probe 6 stably contacts the pin during testing. At the same time, it is convenient to quickly replace or adjust the probe 6 to adapt to diode pins of different heights.

[0026] Through the above specific embodiments, those skilled in the art can easily implement this utility model. However, it should be understood that this utility model is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
