[0002] Waveform testing machines are commonly used testing equipment in the production of electronic components. In order to achieve automated testing, they are usually equipped with a vibration feeding device to automatically and orderly transport the components to be tested to the testing station.

[0003] Vibratory feeding devices generally include a vibratory feeder and a guide rail. The vibratory feeder orients the components, while the guide rail is responsible for discharging the oriented components from the discharge port of the vibratory feeder.

[0004] However, waveform testing machines often need to test a variety of components of different sizes and specifications. In existing vibratory feeding devices, the discharge track is usually fixed to the discharge port of the vibratory feeder using permanent or semi-permanent connection methods such as welding or bolting.

[0005] When it is necessary to replace components of different specifications, this fixed connection method makes it difficult to quickly disassemble and replace the track, requiring a lot of time for adjustment. It is also difficult to quickly adapt to new raw materials, resulting in poor equipment versatility and low production efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example 1

[0022] Please refer to Figures 1 to 4 This utility model provides a vibration feeding device for a waveform testing machine, which aims to solve the structural defects of existing vibration feeding equipment, such as cumbersome and time-consuming track replacement when adapting to raw materials of different sizes, and the lack of effective cleaning function for raw materials before conveying. Figure 1 and Figure 2 As shown, the main body of the vibration feeding device of the waveform testing machine includes a vibratory plate 1, which serves as the core for the output of raw materials, and a track 10 that is detachably connected to the output end of the vibratory plate 1. The vibratory plate 1 is used to automatically sort and directionally convey the scattered raw materials, while the track 10 serves as a connecting component to smoothly guide the sorted raw materials to the subsequent waveform testing machine for testing.

[0023] To enable rapid and stable replacement of the track 10 according to different raw material specifications, a discharge port 9 is extended from the outer wall of the vibratory feeder 1. One end of the track 10 is fitted to the end of the discharge port 9. A positioning hole 12 and a magnetic hole 13 are provided on the end face of the discharge port 9. A magnet is fixedly embedded inside the magnetic hole 13. Correspondingly, a positioning pin 14 and an iron block 11 are fixedly connected to the connecting end face of the track 10. The specifications of the positioning pin 14 are adapted to the positioning hole 12, and the positioning pin 14 is tightly inserted into the positioning hole 12. This mechanical cooperation restricts the displacement of the track 10 in the direction perpendicular to the axis, ensuring that the track 10 is flush with the inner bottom surface of the discharge port 9, preventing... When the raw material is stuck, the position of the iron block 11 corresponds one-to-one with the position of the magnetic hole 13. When the positioning pin 14 is inserted into the positioning hole 12, the iron block 11 is strongly attracted by the magnet in the magnetic hole 13 and tightly attracted together. The magnetic attraction provides axial tension to prevent the track 10 from falling off during use. This connection structure of "precise positioning of positioning pin 14 + quick locking of iron block 11 by magnet attraction" allows the operator to remove the old track 10 by simply applying outward force to overcome the magnetic attraction when replacing the track 10. Then, the positioning pin 14 of the new track 10 is aligned and inserted for automatic attraction and fixation. No threaded fasteners or other auxiliary tools are required, which greatly improves the versatility and changeover efficiency of the equipment.

[0024] To achieve synchronous cleaning and conveying of raw materials before they enter the vibratory feeder 1, the vibration feeding device of this waveform testing machine also includes a guide chute 8. The outlet end of the guide chute 8 is adjacent to the inlet of the vibratory feeder 1. Please refer to the following for details. Figure 1 , Figure 3 and Figure 4A vibrator 18 is fixedly connected to the bottom of the feed trough 8. When the vibrator 18 is working, it drives the feed trough 8 to vibrate, causing the raw material to move forward along the feed trough 8. The feed trough 8 is provided with a drain hole 16 for draining the wastewater after rinsing. The device also includes a cleaning and circulation system, which includes a water tank 2, a water pump 15, a suction pipe 4, an outlet pipe 7, a nozzle 17, and a filter screen 3. The water pump 15 is fixedly installed on the top of the water tank 2. The water pump 15 draws cleaning water from the water tank 2 through the suction pipe 4. One end of the suction pipe 4 is connected to the water pump 15, and the other end extends into the water tank 2. The output end of the water pump 15 is fixedly connected to the nozzle 17 through the outlet pipe 7. The nozzle 17 is located above the feed trough 8 and is used to spray water to rinse the raw materials in the feed trough 8. The rinsed wastewater flows into the water tank 2 directly below through the drain hole 16 on the feed trough 8. A filter screen 3 is fixedly connected inside the water tank 2. The filter screen 3 divides the water tank 2 into a wastewater area and a clean water area. The drain hole 16 is located above the wastewater area. After being filtered by the filter screen 3, the wastewater enters the clean water area. The water intake end of the suction pipe 4 extends into the clean water area, realizing the recycling of clean water. The device also includes a storage hopper 6 and a support frame 5. The discharge port of the storage hopper 6 is located above the starting end of the feed trough 8 and is used to supply raw materials. Both the storage hopper 6 and the feed trough 8 are fixed on the support frame 5.

[0025] Based on the above embodiments, the present invention may further include the following preferred technical solutions: As a preferred embodiment, in order to ensure the cleanliness of the circulating water and prevent impurities from clogging the suction pipe 4 or nozzle 17, the filter screen 3 inside the water tank 2 is used to clearly divide the internal volume of the water tank 2 into a sewage area and a clean water area. The drain hole 16 on the feed trough 8 is directly opposite the sewage area, so that the sewage carrying impurities that is flushed down first enters the sewage area. After being filtered by the physical barrier of the filter screen 3, only clean water can pass through the filter screen 3 and enter the clean water area. The water intake end of the suction pipe 4 is arranged deep in the clean water area, thereby ensuring that the water pump 15 always draws out filtered clean water.

[0026] As another preferred embodiment, in order to optimize the overall layout of the equipment and the convenience of maintenance, the water pump 15 is not submerged in water, but is fixedly installed on the top of the water tank 2. This top-mounted installation method avoids long-term immersion corrosion of the pump body, and also facilitates maintenance and replacement. The suction pipe 4 extends vertically downward through the top of the water tank 2 and into the liquid surface.

[0027] As a further preferred embodiment, in order to achieve automatic and continuous supply of raw materials and ensure the stability of the cleaning process, the support frame 5 serves as the supporting foundation for the entire feeding front end. The storage hopper 6 is fixedly installed at a high position on the support frame 5, and the guide chute 8 is installed on the support frame 5 and located below the discharge port of the storage hopper 6, so that the raw materials fall naturally into the guide chute 8 under gravity and are evenly distributed. Then, under the excitation force of the vibrator 18, they pass through the spray area in an orderly manner. As a further refinement of the connection structure, in order to ensure the end face fit between the track 10 and the vibrating plate 1 when docking, the positioning hole 12 and the magnetic hole 13 are both opened on the end face of the discharge port 9. The positioning pin 14 and the iron block 11 are correspondingly set on the connecting end face of the track 10, so that the two flat end faces fit together when docking, avoiding gaps caused by structural interference and ensuring the smoothness of the raw material transition.

[0028] Working principle: When the raw materials need to be cleaned and transported, the raw materials fall from the storage hopper 6 fixed on the support frame 5 into the guide trough 8. The vibrator 18 at the bottom of the guide trough 8 is fixedly connected to the guide trough 8. When the vibrator 18 works, it drives the guide trough 8 to vibrate, so that the raw materials in the guide trough 8 move forward while being vibrated and transported and finally enter the vibrating plate 1. During the movement of raw materials, the water pump 15, which is fixedly installed on the top of the water tank 2, is started. The suction pipe 4 connected to one end of the water pump 15 extends into the water tank 2 to draw clean water. The water flows through the water pump 15 and is transported to the outlet pipe 7. The end of the outlet pipe 7 is fixedly connected to multiple nozzles 17 located above the guide trough 8. The clean water is sprayed out through the nozzles 17 to rinse the raw materials in the guide trough 8. The rinsed wastewater, carrying impurities, flows back to the water tank 2 directly below through the drain hole 16 opened on the guide trough 8. The filter screen 3 fixedly connected inside the water tank 2 filters the incoming wastewater. The filtered water is drawn again by the suction pipe 4 in the clean water area to realize the recycling of clean water. Through the coordinated work of the vibrator 18 and the cleaning system, the synchronous operation of cleaning and conveying is completed.

[0029] When the track 10 needs to be replaced to accommodate raw materials of different sizes, the operator applies an outward pulling force to the track 10. The iron block 11 fixed at one end of the track 10 is released from the magnetic attraction of the magnet fixed inside the magnetic hole 13 at one end of the discharge port 9. At the same time, the positioning pin 14 fixed at one end of the track 10 separates from the positioning hole 12 at one end of the discharge port 9. At this time, the track 10 is separated from the discharge port 9 on the vibrating plate 1. When installing a new track 10, the positioning pin 14 on the new track 10 is aligned with the positioning hole 12 on the discharge port 9 of the vibrating plate 1 and inserted. The insertion and engagement of the positioning pin 14 and the positioning hole 12 provides precise physical positioning. During this process, the iron block 11 on the new track 10 approaches the magnetic hole 13. The magnet inside the magnetic hole 13 generates a magnetic attraction force to attract and fix the iron block 11. Through the precise positioning of the positioning pin 14 and the magnetic attraction and fixation of the iron block 11 and the magnet, the rapid replacement of the track 10 and the stability during vibration operation are achieved.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
