DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0022] Please refer to Figure 1-4 ;
[0023] A rivet missing detector includes a reinforcement frame 1 and an audible and visual alarm 2 and a power supply 3 arranged on the side wall of the reinforcement frame 1. A partition 4 is provided in the reinforcement frame 1. A plurality of reset switches 5 electrically connected to the audible and visual alarm 2 and the power supply 3 are provided between the partition 4 and the reinforcement frame 1. When all the reset switches 5 are pressed, a sound is emitted. If a reset switch 5 is not pressed, no sound is emitted. Several reset switches 5 extend upward and pass through the partition 4. Several reset switches 5 are provided with tray plates 6. The tray plates 6 are used to place the motherboard tray. The tray plates 6 are provided with several through holes 63 corresponding to the reset switches 5. The through holes 63 are used for installing and positioning the motherboard tray. Specifically, the rivets on the motherboard tray are aligned with the through holes 63. Hole 1 63 is placed so that each rivet forms a linear correspondence with the reset switch 5 below it. A number of buffer springs 7 are provided at the lower end of the tray plate 6 to absorb the impact force generated when the tray plate 6 descends, and prevent the mainboard tray on the tray plate 6 from being damaged due to sudden pressure changes. A positioning column 61 is provided in each of the buffer springs 7 and is integrated with the tray plate 6. A positioning hole 41 corresponding to the positioning column 61 is provided on the partition 4. When the tray plate 6 is subjected to a decrease in pressure during detection, the positioning column 61 will slide downward in the positioning hole 41, ensuring the stability and balance of the tray plate 6 when it descends. After the detection is completed, the buffer spring 7 is restored and automatically lifts the tray plate 6, making it convenient for the operator to take out the mainboard tray.
[0024] Specifically, place the motherboard tray on the tray plate 6, start the punch press to apply pressure on it, so that the tray plate 6 drives the motherboard tray down until the rivets on the motherboard tray contact the reset switch 5 and trigger the switch. When all the reset switches 5 are pressed correctly, the system sound and light alarm 2 will make a sound to indicate that the inspection is passed. If any rivet is misplaced or missing, resulting in the switch not being fully triggered, the sound and light alarm 2 will not sound, indicating that the motherboard tray is unqualified. After the inspection is completed, the punch press is lifted, the buffer spring 7 is reset, and the tray plate 6 is automatically lifted, making it convenient for the operator to remove the motherboard tray, and the above steps are repeated to inspect the motherboard tray to be inspected.
[0025] In this embodiment, the positioning column 61 extends downward through the positioning hole 41 and is provided with an external thread at the lower end, and a nut 62 is connected to the external thread. The nut 62 can contact the lower end surface of the partition 4. The nut 62 is used to limit the rising height of the tray plate 6 to prevent the tray plate 6 from rising too high and the positioning column 61 from being separated from the positioning hole 41, thereby requiring the tray plate 6 to be re-positioned and installed.
[0026] In this embodiment, four buffer springs 7 are provided, and the four buffer springs 7 are arranged diagonally, so as to effectively disperse the pressure and ensure that the forces in all directions of the tray plate 6 can be evenly handled when it descends, thereby improving the stability during the detection process and ensuring the stability of the tray plate 6 when it rises.
[0027] In order to facilitate the installation and replacement of the buffer spring 7 and solve the problem of its possible deformation under long-term pressure, after removing the tray plate 6, unscrew the nut 62 on the positioning column 61 to separate the partition 4 from the tray plate 6, and replace the buffer spring 7 to extend the service life of the detection instrument.
[0028] In this embodiment, four supporting sleeves 42 are provided at the lower end of the partition 4, and a groove 12 corresponding to the supporting sleeve 42 is provided at the bottom of the reinforcement frame 1. A threaded hole 14 is provided in communication with the supporting sleeve 42 and the groove 12. The threaded hole 14 is threadedly connected to a screw 13. The partition 4 is locked by using the screw 13 to prevent the partition 4 from being lifted up by the tray plate 6. At the same time, the head of the screw 13 after tightening is located inside the groove 12 and is not exposed on the bottom surface of the reinforcement frame 1, thereby ensuring the flatness of the bottom surface of the equipment.
[0029] To facilitate removal of the tray plate 6 for maintenance and replacement of the reset switch 5 and cleaning of the interior of the reinforcement frame 1, two through-holes 11 are provided on each side of the reinforcement frame 1. The tray plate 6 can be manually removed through the through-holes 11. Because the partition 4 and tray plate 6 are attached together by nuts 62 at the lower ends of the positioning posts 61, it is necessary to first remove the screws 13 at the bottom of the reinforcement frame 1 that secure the partition 4 before removing the tray plate 6. This allows the tray plate 6 and the partition 4 to be removed directly.
[0030] In this embodiment, the power supply 3 is electrically connected to the sound and light alarm 2, the power supply 3 is electrically connected to the reset switch 5, and the sound and light alarm 2 is electrically connected to the reset switch 5. Specifically, the power supply 3 uses 24V DC power to provide power to the sound and light alarm 2, which is used to emit a light alarm through the sound and light alarm 2, making it convenient for staff to clearly know whether the mainboard tray has passed the inspection.
