[0021] Please see Figure 1-5 This embodiment provides a steel ball feeding device for installing steel balls 300 in the vertical groove 200 of the magnetic core 100. The steel ball feeding device includes: The feeding mechanism 1 includes a material collection chamber 11, a material trough 12, a material picking head 13, and a feeding cylinder 14. The material collection chamber 11 is used to place the steel balls 300 and is connected to the material trough 12. The material picking head 13 is installed at the output end of the feeding cylinder 14 and passes through the material trough 12. The feeding cylinder 14 is used to drive the material picking head 13 to lift from the bottom of the material trough 12 and lift one of the steel balls 300. Mounting platform 2, which is used to place the magnetic core 100 to be installed, and a funnel 21 is provided on the mounting platform 2. The funnel 21 has a channel 22 that connects from top to bottom to the vertical groove 200 of the magnetic core 100. The material conveying mechanism 3 includes a guide rail 31, a guide rail motor 32, a fixing plate 33, a material picking cylinder 34, and a material picking arm 35. The guide rail 31 is disposed between the feeding mechanism 1 and the mounting platform 2. The fixing plate 33 is mounted on the guide rail 31. The guide rail motor 32 is used to drive the guide rail 31 to move the fixing plate 33 between the feeding mechanism 1 and the mounting platform 2. The material picking cylinder 34 is mounted on the fixing plate 33. The material picking arm 35 is mounted on the output end of the material picking cylinder 34. The material picking cylinder 34 is used to drive the material picking arm 35 to move in the vertical direction.

[0022] With the above structure, during use, the operator only needs to place the corresponding number of steel balls 300 in the collection chamber 11 and install the magnetic core 100 under the funnel 21 on the mounting platform 2. The steel balls 300 can slide from the collection chamber 11 into the material trough 12. In the default state, the top of the picking head 13 is lower than the lowest position of the material trough 12. After the feeding cylinder 14 is started, the picking head 13 is raised, so that one steel ball 300 in the material trough 12 that is exactly above the picking head 13 is lifted.

[0023] Then, the material conveying mechanism 3 begins to pick up materials. The guide rail motor 32 drives the guide rail 31 to run, so that the fixed plate 33 on one side of the guide rail 31 drives the picking cylinder 34 to move directly above the picking head 13. Then the picking cylinder 34 drives the picking arm 35 to move downward, so that the picking arm 35 approaches the top of the picking head 13, until the steel ball 300 at the top of the picking head 13 is picked up by the bottom of the picking arm 35.

[0024] After the material is picked up, the picking cylinder 34 drives the picking arm 35 to reset. Then, the guide rail motor 32 drives the guide rail 31 to run, so that the fixing plate 33 on one side of the guide rail 31 drives the picking cylinder 34 to move directly above the funnel 21 of the mounting platform 2. After it is in place, the picking arm 35 releases the steel ball 300 at its end, so that the steel ball 300 falls into the channel 22 of the funnel 21. The steel ball 300 enters the channel 22 from the inlet at the top of the channel 22 and slides to the outlet at the bottom of the channel 22. Then, under the guidance, it slides directly into the vertical groove 200 of the magnetic core 100. Thus, the device of this application can complete the installation of the steel ball 300.

[0025] The output end of the aforementioned material handling cylinder 34 can be configured as a motor shaft assembly for transmission, which drives the corresponding downstream component to reciprocate through the stroke motion.

[0026] Based on the above structure, the steel ball 300 can be quickly picked up by the picking head 13 passing through the material trough 12, and then quickly picked up and installed with the help of the picking arm 35, resulting in high installation efficiency. Specifically, when picking up the steel ball 300, the picking head 13 only needs to move up and down under the drive of the picking cylinder 14 to lift the steel ball 300 at the corresponding position in the material trough 12. Then, it can be quickly picked up by the picking arm 35 and placed into the funnel 21. The steel ball 300 is guided and installed by its own weight through the channel 22 of the funnel 21. No manual intervention is required, the picking speed is fast, the picking error rate is low, and it helps to improve the yield rate.

[0027] Furthermore, the steel ball feeding device also includes a detection cylinder 36 and a detection probe 37. The detection cylinder 36 is mounted on the fixed plate 33, and the detection probe 37 is mounted on the output end of the detection cylinder 36. The detection cylinder 36 is used to drive the end of the detection probe 37 through the funnel 21 into the vertical groove 12 of the magnetic core to detect whether the steel ball 300 is installed in place. Specifically, the detection probe 37 can be configured as a vertically extending rod-shaped structure with a diameter smaller than the inner diameter of the vertical groove 200. After the steel ball 300 is installed in the above steps, the guide rail motor 32 drives the guide rail 31 to run, causing the fixed plate 33 on one side of the guide rail 31 to move the detection cylinder 36 to directly above the funnel 21 of the mounting platform 2. Then, the detection cylinder 36 drives the detection probe 37 to press down, causing the detection probe 37 to pass through the channel 22 and extend to the corresponding position in the vertical groove 200 where the steel ball 300 is pre-installed. If the steel ball 300 is installed in place, its presence can be detected.

[0028] In another embodiment, a laser detector 38 is installed on the top of the feed trough 12. The output end of the laser detector 38 is positioned facing the top of the raised feeding head 13. The laser detector 38 is used to detect whether the top of the feeding head 13 has picked up the steel ball 300. In special circumstances, such as when the feeding head 13 runs out of steel balls, the laser emitted by the laser detector 38 cannot reach the steel ball 300, and the top of the feeding head 13 passes through it. Therefore, the machine can be stopped to remind the operator to replenish the material.

[0029] See this application for details. Figure 4In the cross-sectional view, the top surface of the material trough 12 is configured as a concave arc-shaped surface, so that the steel balls 300 in the material trough 12 can roll down to the lowest point of the arc-shaped surface. Similarly, the picking head 13 is configured to pass through the lowest point of the arc-shaped surface, so that when multiple steel balls 300 are placed in the material trough 12, at least one steel ball 300 can always roll down to the top position of the picking head 13 before it is raised. Therefore, when steel balls 300 enter the material trough 12, the steel balls 300 can move along the concave arc-shaped surface, and there will always be one steel ball 300 that can roll down to the top of the picking head 13 at the lowest point.

[0030] See further details in this application. Figure 4 The cross-sectional view shows that the bottom of the collection bin 11 is configured as an inclined surface sloping downwards from the collection bin 11 towards the trough 12, so that the steel ball 300 in the collection bin 11 can roll down the inclined surface into the trough 12. In other words, this application makes full use of the geometric features of the steel ball 300, using gravity to guide the direction of the steel ball 300.

[0031] Furthermore, an air intake 351 is connected to one side of the picking arm 35. The air intake 351 is connected to the bottom of the picking arm 35, and the picking arm 35 uses air drawn from the air intake 351 to create a negative pressure at the bottom of the picking arm 35 to pick up the steel ball 300. The input end of the air intake 351 is connected to an external negative pressure device, which is used to suck up the steel ball 300 at the end of the picking arm 35.

[0032] In one embodiment, the magnetic core 100 is actually provided with a plurality of vertical slots 200 spaced at equal angles. Each vertical slot 200 needs to be equipped with a steel ball 300. Therefore, the aforementioned detection probe 37, laser detector 38, air intake 351 and other devices can be arranged in multiple ways at equal angles around the center point, so that the same picking arm 35 can simultaneously perform interactive operations on multiple steel balls 300.

[0033] The above-disclosed content is only a preferred and feasible embodiment of the present utility model, and is not intended to limit the scope of the patent application of the present utility model. Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.

[0034] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0035] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
