Description

Technical Field

[0001] This utility model relates to the field of pressure detection technology, and in particular to a pressure detection machine with a spring-loaded pin. Background Technology

[0002] Spring ejector pins are widely used components in various fields. Their main function is to protect fingers or support workpieces. Depending on the application and specific use, spring ejector pins can be classified into several types, especially in the precision equipment industry, such as squeegees for printing presses, accessories for SMT equipment, and probes for connectors. During the manufacturing process of spring ejector pins, to prevent bending and breakage due to insufficient material strength during use, which would reduce operational stability, pressure testing is required after production. Since different types of spring ejector pins have different strengths, the pressure they can withstand also varies. Therefore, the pressure of the spring ejector pin strength testing device needs to be adjusted accordingly for different types of spring ejector pins. However, most existing spring ejector pin strength testing devices use manual adjustment, which has low precision and requires repeated adjustments, making the operation time-consuming, labor-intensive, and affecting testing efficiency.

[0029] The present invention will now be described in detail with reference to the accompanying drawings.

[0030] like Figures 1 to 2 As shown, the pressure testing machine for spring ejector pins 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 detection component 4 disposed on the seat 2, a pickup component 5 used in conjunction with the detection component 4, a collection component 6 used in conjunction with the pickup component 5, a material tray 7 for carrying spring ejector pins from the outside, and a Y-axis module 8 for driving the material tray 7 to move along the Y-axis direction of the base frame 1. The moving direction of the seat 2 is perpendicular to the moving direction of the material tray 7. The X-axis module 3, the detection component 4, the pickup component 5, the collection component 6, and the Y-axis module 8 are all electrically connected to a PLC control system.

[0031] During operation, since the X-axis module 3, detection component 4, pickup component 5, collection component 6, and Y-axis module 8 are all electrically connected to the PLC control system (not shown), by inputting relevant operating parameters into the PLC control system, the PLC control system intelligently controls the efficient and coordinated operation between each component. The Y-axis module 8 drives the material tray 7 to move along the Y-axis direction of the base frame 1. The X-axis module 3, through the base 2, jointly drives the detection component 4 and pickup component 5 to move to the predetermined position. First, the detection component 4 moves downward and abuts against the spring pin to apply the rated pressure. The detection component 4 immediately records the pressure received by the spring pin to observe the intensity of the spring pin detection. When the detection component 4 detects that the pressure received by the spring pin exceeds 100± When the pressure reaches 20mN, the spring pin is determined to be defective, and a corresponding detection signal is sent to the PLC control system. The PLC control system analyzes and processes the detection signal and issues a working command to the pickup component 5. The pickup component 5 then picks up the defective spring pin from the tray 7. Simultaneously, the material box 62 rotates via the rotary motor 63 to a position directly below the pickup component 5, facilitating the release of the defective spring pin and ensuring its accurate placement within the box. Finally, the material box 62 rotates away from the pickup component 5 via the rotary motor 63, allowing the pickup component 5 to pick up the next defective spring pin. This method achieves high pickup efficiency for defective spring pins, eliminates the need for manual pressure adjustment, and improves the accuracy of spring pin strength detection. This invention utilizes a PLC control system to intelligently control the efficient and coordinated operation of the X-axis module 3, detection component 4, pickup component 5, collection component 6, and Y-axis module 8. It eliminates the need for manual adjustment of the detection pressure of the detection component 4, effectively saving labor costs and improving detection efficiency.

[0032] The 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 pressure sensors 43 disposed on the first lifting seat 41. Multiple pressure sensors 43 are provided, spaced apart and arranged in parallel. Specifically, the first driving member 42 drives the pressure sensors 43 to move up and down via the first lifting seat 41. The multiple pressure sensors 43, spaced apart and arranged in parallel on the first lifting seat 41, enable pressure detection of multiple spring pins at a time, improving work efficiency. The pressure sensors 43 can sense the magnitude of the applied pressure, facilitating observation of the intensity of the spring pin detection. The pressure sensors 43 are electrically connected to an external display screen, clearly displaying the specific value of the pressure sensed by the pressure sensors 43, facilitating observation of the pressure values ​​borne by the spring pins at different stages.

[0033] 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 the pressure sensor 43 set on the first lifting seat 41 can accurately sense the magnitude of the applied pressure, resulting in high detection accuracy.

[0034] 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 defective spring pins from the material tray 7, 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 pins and accurately store them 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, resulting in high work coordination.

[0035] 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 are spaced apart and arranged in parallel on the second lifting seat 51, and in conjunction with the Y-axis module 8 driving the material tray 7 to move back and forth, which helps the gripper cylinders 53 drive the gripper arm 54 to open or close, facilitating the picking up of multiple defective spring pins from the material tray 7 and releasing them into the material box 62, thereby increasing the picking speed of defective spring pins.

[0036] 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 defective spring pins through the gripper arm 54, and ensures good working stability.

[0037] In this embodiment, the base 2 is provided with a slider 21, and the base frame 1 is provided with a guide rail 11 that is slidably connected to the slider 21. The guide rail 11 extends along the length of the base frame 1. Specifically, when the X-axis module 3 drives the detection component 4 and the pickup component 5 to move and reach the predetermined position through the base 2, the base 2 is slidably connected to the guide rail 11 through the slider 21, thereby reducing frictional resistance and making the movement smooth and rapid.

For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model.
