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

[0032] like Figures 1 to 3 As shown, the impedance testing machine for a spring ejector pin of this utility model includes a base frame 1, a seat 2 movably disposed on the base frame 1, an X-axis module 3 for driving the seat 2 to move along the X-axis direction of the base frame 1, a first detection component 4 disposed on the seat 2, a pickup component 5 used in conjunction with the first detection component 4, a collection component 6 used in conjunction with the pickup component 5, a material tray 8 for carrying the spring ejector pin 7, and a second detection component 9 used in conjunction with the material tray 8. The second detection component 9 abuts against the outer wall of the material tray 8, and the first detection component 4 protrudes into the spring ejector pin 7 so that the first detection component 4, the spring ejector pin 7, the material tray 8, and the second detection component 9 form an electrical circuit.

[0033] During operation, the X-axis module 3 drives the first detection component 4, the pickup component 5, and the collection component 6 to move together via the base 2 and reach above the material tray 8. First, the first detection component 4 moves downwards and abuts against the connecting spring pin 7. Simultaneously, the second detection component 9 abuts against the outer wall of the material tray 8, forming an electrical circuit with the first detection component 4, the spring pin 7, the material tray 8, and the second detection component 9. This enables impedance detection of the spring pin 7. Impedance is the resistance to alternating current in a circuit; it can be defined as the ratio of voltage to current, and its unit is ohms (Ω). Then, the second detection component... Component 9 accurately detects the impedance value. When the impedance value is greater than 35mΩ, the spring pin 7 is determined to be defective. The second detection component 9 sends a corresponding detection signal to the PLC control system. After analyzing and processing the detection signal, the PLC control system issues a working command to the pickup component 5. Then, the pickup component 5 picks up the defective spring pin 7 from the tray 8. At the same time, the collecting component 6 rotates to be directly below the pickup component 5, facilitating the release of the defective spring pin 7 by the pickup component 5. This ensures that the defective spring pin 7 is accurately stored in the collecting component 6, resulting in high pickup efficiency. This invention improves impedance detection efficiency by forming an electrical circuit between the first detection component 4, the spring pin 7, the tray 8, and the second detection component 9, meeting the needs of large-scale automated impedance detection of spring pins 7.

[0034] The second detection component 9 in this embodiment includes a sliding seat 91, a Y-axis module 92 drivenly connected to the sliding seat 91, a driving cylinder 93 disposed on the sliding seat 91, a second detection probe 94 drivenly connected to the driving cylinder 93, and a test lead 95 electrically connected to the second detection probe 94. The moving direction of the sliding seat 91 is perpendicular to the moving direction of the second detection probe 94, and the second detection probe 94 is driven by the driving cylinder 93 to abut against the outer wall of the material tray 8. Specifically, the Y-axis module 92 drives the drive cylinder 93 to move back and forth via the sliding seat 91. The drive cylinder 93 drives the second detection probe 94 to move left and right. The second detection probe 94 is driven by the drive cylinder 93 to abut against the outer wall of the material tray 8, ensuring that the detection end of the second detection probe 94 is in contact with the outer wall of the material tray 8, so that testing can be performed. The test lead 95 forms a test circuit with the external display screen (not shown). The external display screen is electrically connected to the PLC control system. The operator can clearly see the actual impedance value detected through the external display screen. The actual impedance value marked in red is a defective product, and the actual impedance value marked in green is a good product.

[0035] The first detection component 4 in this embodiment includes a first lifting seat 41, a first driving member 42 drivenly connected to the first lifting seat 41, and a first detection probe 43 disposed on the first lifting seat 41. Multiple first detection probes 43 are provided, spaced apart and arranged in parallel. Specifically, the first driving member 42 drives the first detection probes 43 to move up and down via the first lifting seat 41. The multiple first detection probes 43, spaced apart and arranged in parallel on the first lifting seat 41, enable impedance detection of multiple spring pins 7 in a single operation, improving detection efficiency.

[0036] The first driving component 42 in this embodiment includes a first coupling 421, a first servo motor 422 drivenly connected to the first coupling 421, a first lead screw 423 connected to the first coupling 421, and a first nut 424 sleeved and screwed onto the outside of the first lead screw 423. The first nut 424 is connected to the first lifting seat 41. Specifically, the first servo motor 422 drives the first lead screw 423 to rotate through the first coupling 421. The rotating first lead screw 423 drives the first lifting seat 41 to move up and down along the seat body 2 through the first nut 424. The transmission efficiency is high, so that the first detection probe 43 set on the first lifting seat 41 accurately contacts the spring pin 7, resulting in high detection accuracy.

[0037] The collection component 6 in this embodiment includes a base 61, a material box 62 movably disposed on the base 61, and a rotary motor 63 drivenly connected to the material box 62. The base 61 is disposed on the seat body 2, and the material box 62 is driven by the rotary motor 63 to move closer to or away from the pickup component 5. Specifically, the pickup component 5 picks up the defective spring pin 7 from the material tray 8, and then the material box 62 is rotated by the rotary motor 63 to be directly below the pickup component 5, so that the pickup component 5 can release the defective spring pin 7, allowing the defective spring pin 7 to be accurately stored in the material box 62. Finally, the material box 62 is rotated by the rotary motor 63 to move away from the pickup component 5, so that the pickup component 5 can continue to pick up the next defective spring pin 7, resulting in high work coordination.

[0038] The picking component 5 in this embodiment includes a second lifting seat 51, a second driving member 52 drivenly connected to the second lifting seat 51, a gripper cylinder 53 disposed on the second lifting seat 51, and a gripper arm 54 drivenly connected to the gripper cylinder 53. Multiple gripper cylinders 53 are provided, spaced apart and arranged in parallel. Specifically, the second driving member 52 drives the gripper cylinders 53 to move up and down via the second lifting seat 51. The multiple gripper cylinders 53, spaced apart and arranged in parallel on the second lifting seat 51, facilitate the gripper cylinders 53 driving the gripper arm 54 to open or close, making it easier to pick up multiple defective spring pins 7 from the material tray 8 and release them into the material box 62, thereby increasing the picking speed of defective spring pins 7.

[0039] The second driving component 52 in this embodiment includes a second coupling 521, a second servo motor 522 driven by the second coupling 521, a second lead screw 523 connected to the second coupling 521, and a second nut 524 screwed onto the outside of the second lead screw 523. The second nut 524 is connected to the second lifting seat 51. Specifically, the second servo motor 522 drives the second lead screw 523 to rotate through the second coupling 521. The rotating second lead screw 523 drives the second lifting seat 51 to move up and down along the seat body 2 through the second nut 524. This results in high transmission efficiency, facilitates the gripper cylinder 53 to accurately pick up or release the defective spring pin 7 through the gripper arm 54, and ensures good working stability.

[0040] In this embodiment, multiple spring ejector pins 7 are arranged in a rectangular array. Specifically, the multiple spring ejector pins 7 are arranged in a rectangular array on the material tray 8, effectively meeting the needs of large-scale inspection of the spring ejector pins 7.
