In the transmission process of the magnetic control coil, the manual visual inspection and manual cleaning of the blocked coil are needed throughout the process, which not only causes the waste of manpower and increases the cost, but also has low efficiency. In the automatic production line, the manual cleaning of the blockage seriously affects the production efficiency, and the internal structure of the coil conveying pipeline is small and cannot be touched by hand, so that the manual operation factor needs to be considered in the production line, which not only causes the design trouble, but also causes the personnel operation trouble, and the personnel need to concentrate on the whole production line at all times, which cannot meet the demand of the current market mass production.

[0036] Please see Figs. 1 to 7 As shown, this utility model provides a coil conveying device that can automatically clear blockages. In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In a specific embodiment of the technical solution of this utility model:

[0038] Includes cylinder 1, bottom guide mold 11, frame 14, unloading chute 2, clearing plate 3, and top guide mold 4;

[0039] Frame 14 is a fixed frame structure;

[0040] The clearing plate 3 is a flat plate, which is vertically and stably installed on the frame 14. An air inlet 31 is opened on the side wall of the clearing plate 3, which is connected to an external air blowing pipe. A solenoid valve can be added to the air blowing pipe as an air valve, and the air valve is connected to the controller. An air blowing port 32 is opened on the rear side wall of the clearing plate 3, and the air inlet 31 is connected to the air blowing port 32. The air inlet 31 and the air blowing port 32 are connected through the internal pipe of the clearing plate 3. The air blowing port 32 is aligned with the opening of the lower mold groove 12 in the descending position, so that the blown air can directly face the lower mold groove 12 and blow the blocked material out of the lower mold groove 12. A recycling box 13 is also set directly below the lower mold groove 12. The recycling box 13 is a box with an open top. By blowing air, the material of the feeding chute 2 is blown into the recycling box 13.

[0041] The feeding chute 2 is a top-opening guide groove, and both the front and rear ends of the feeding chute 2 are open;

[0042] The material feeding chute 2 is inclined and inserted into the block cleaning frame plate 3 with the front higher than the back, and the material feeding chute 2 penetrates the front and rear sides of the block cleaning frame plate 3; the rear opening of the material feeding chute 2 is flush with the rear side wall of the block cleaning frame plate 3.

[0043] The feeding chute 2 is a V-shaped guiding groove. The left and right sides of the feeding chute 2 are symmetrically arranged, and the two sides of the feeding chute 2 are perpendicular to each other, that is, the included angle α is 90°. This facilitates the guidance and conveying of cylindrical coil materials, and also prevents the materials from rolling in the left and right directions, ensuring accurate material conveying. At the same time, the top of the feeding chute 2 is open, and the proximity switch 21 can easily detect the materials through the open conveying groove. If it is not open, the materials in the feeding chute 2 will be blocked, and the proximity switch 21 will not be able to detect the materials normally.

[0044] A proximity switch 21 is installed on the outside of the feeding chute 2. The detection direction of the proximity switch 21 is directly facing the inside of the groove of the feeding chute 2. The proximity switch 21 is installed on the front side wall of the clearing frame plate 3. The proximity switch 21 is directly facing the top opening of the feeding chute 2 from top to bottom, which facilitates the detection of the coil material on the feeding chute 2 with the top opening and checks whether the material is being conveyed normally.

[0045] The cylinder 1 is fixedly mounted vertically on the frame 14, with the telescopic rod of the cylinder 1 facing downwards and set vertically.

[0046] The bottom mold 11 is a block structure. The top of the bottom mold 11 is a sloping surface that is higher in the front and lower in the back. A lower mold groove 12 is opened on the top of the bottom mold 11. The lower mold groove 12 is recessed downward and opened on the top sloping surface of the bottom mold 11. The bottom mold 11 is suspended from the lower end of the telescopic rod of the cylinder 1.

[0047] The upper guide mold 4 is a block structure. The upper guide mold 4 is fixedly mounted on the rear side wall of the clearing plate 3. The bottom of the upper guide mold 4 is a slope with a higher front and a lower back. The upper mold groove 41 is recessed upward on the bottom slope of the upper guide mold 4. The discharge port 42 is a round hole on the rear side wall of the upper guide mold 4.

[0048] A baffle can be vertically installed on the rear side wall of the upper guide mold 4 to block the blown-out entangled material, so that the entangled material falls vertically downward into the recycling box 13, preventing the previously stuck material from bouncing backward and in all directions, and also preventing the entangled material from falling into other material transfer bins behind, but collecting it in a concentrated manner for subsequent processing.

[0049] The bottom guide mold 11 is vertically raised and lowered by the cylinder 1 and positioned directly below the top guide mold 4. The top slope of the bottom guide mold 11 and the bottom slope of the top guide mold 4 can be separated and tightly fitted together. The bottom guide mold 11 and the top guide mold 4 can be 3D printed to ensure that the upper mold groove 41 and the lower mold groove 12 match the shape of the coil. The bottom mold is thicker at the front and thinner at the back, which can guide and transport the coil. The bottom mold 11 and the top guide mold 4 can also constrain the output direction and position of the coil at the rear outlet.

[0050] The upper mold groove 41 and the lower mold groove 12 are assembled into a funnel-shaped closed channel that is thicker at the front and thinner at the back. The channel assembled by the upper mold groove 41 and the lower mold groove 12 is also inclined at the front and lower at the back. The rear opening of the channel formed by the upper mold groove 41 and the lower mold groove 12 is aligned and connected with the discharge port 42.

[0051] The top inclined surface of the bottom mold 11 and the top inclined surface of the top mold 4 have the same inclination angle, and the angle b with the horizontal plane is 25°. The channel axis formed by the upper mold groove 41 and the lower mold groove 12 also has an angle of 25° with the horizontal plane.

[0052] A connecting pipe 43 is also provided on the rear side of the upper guide mold 4. The connecting pipe 43 is also inclined and is connected to the rear end of the discharge port 42. The axis of the discharge port 42 and the connecting pipe 43 coincide. The inclined angle allows the coil material to slide smoothly backward. The inclined angle is not large to avoid the material from flipping and bouncing due to rapid sliding.

[0053] This device also requires a controller, which can be an STM32 microcontroller. STM32 is a commonly used motor control board, readily available and easy to operate. The controller must ensure that cylinder 1 can operate normally. It also needs to monitor the signal from proximity switch 21. When an abnormal signal occurs, the controller will lower cylinder 1 and activate an audible and visual alarm. The alarm will issue an abnormality notification when proximity switch 21 shows a continuous signal. Even if repeated air blowing to clear the blockage is ineffective, the alarm will still sound, prompting personnel to handle the situation promptly.

[0054] The controller also controls an external air source to blow air into the air inlet 31, which is then blown out through the air outlet 32. This blows the coil stuck in the horn-shaped pipe backward, causing it to fall through the gap between the opening at the rear end of the lower die groove 12 and the baffle, and then into the recycling box 13. This facilitates the collection of coil material that has become blocked due to entanglement, and then it can be centrally processed or scrapped. Furthermore, the guide die 11 lowers downward, which separates the lower die groove 12 from the upper die groove 41, forming two separate halves of the horn-shaped opening. This further increases the opening for the entangled material. The lowered lower die groove 12 is aligned with the air outlet 32, allowing air to be blown in, thus separating the lower die groove 12 from the coil material. Furthermore, when the bottom mold 11 is lowered to its lowest point, the speed of the bottom mold 11 suddenly decreases, generating vibration. This results in non-impact vibration without contact with any object, ensuring that the coil material will not get stuck with the bottom mold 11. This facilitates the separation of stuck coils, and the vibration does not affect the normal operation of the equipment or damage it.

[0055] It should be noted that:

[0056] 1. Electromagnetic coils have an intermittent helical structure, as do springs. Two parallel coils will interlock along the gap to form a longer coil. This requires dispersing the two interlocked coils. These completely de-interlocked coils can be automatically conveyed. There is also a type of coil that intertwines to form a branch-like winding, usually in a Y-shape. This forked coil can block the pipe opening, causing blockage in the conveying line. Previously, manual sorting was performed at the front end of the material to separate these branch-like coils before conveying them. Now, this device does not require personnel to be on duty. Instead, the upper guide mold 4 remains stationary while the lower guide mold 11 is lowered, making the channel split. The structure is more flexible. The lower guide mold 11 can automatically lower and automatically unwind the coils. These are functions that existing devices do not have. Moreover, the lower guide mold 11 and the upper guide mold 4 can be tightly spliced ​​together to form a complete closed channel, which facilitates coil conveying.

[0057] 2. In existing devices, unblocking usually involves blowing air or pushing to push the material away from the side. However, for electromagnetic coils with a certain degree of elasticity that get stuck in the channel between the lower mold groove 12 and the upper mold groove 41, simply pushing may only deform the coil and cannot remove it from the channel. This device not only opens the channel but also lowers the bottom mold 11 and slightly impacts the top of the recycling box 13 below the bottom mold 11. Through the simultaneous action of vibration and blowing air, and by dividing the channel in two and opening it up vertically, it further facilitates the coil's escape. It requires no manual operation and is truly automated, removing the entangled and stuck coil from the channel and automatically unblocking it.

[0058] In use, the material is continuously fed into the feeding chute 2 by the previous process. The material will slide backward along the inclined feeding chute 2. When the material passes through the proximity switch 21, it is detected by the switch and the detection signal is quickly lost, which means that the material passes through smoothly. If the material is continuously detected and there is no disconnection, it means that the material is stuck.

[0059] The controller will control the cylinder 1 to extend, the bottom guide mold 11 to lower, and the top guide mold 4 to remain stationary. The bottom guide mold 11 and the top guide mold 4 will separate, causing the funnel-shaped channel formed by the lower mold groove 12 and the upper mold groove 41 to open, releasing the material from the channel. At the same time, the bottom guide mold 11 will descend and gently impact the top of the recycling box 13, creating vibration. Even if the material is stuck in the groove, it will fall off.

[0060] At the same time, the front end of the lowered upper mold groove 12 is aligned with the air blowing port 32. The gas blown out of the air blowing port 32 blows the material stuck in the upper mold groove 12 backward and falls into the recycling box 13, thus completing the material sorting.

[0061] When cylinder 1 shortens, the bottom guide mold 11 rises and closes with the upper guide mold 4 again. If the proximity switch 21 still detects that there is material stuck, cylinder 1 extends again and controls the bottom guide mold 11 to lower again to clear the blockage. If there is no material in the lower mold groove 12 and the upper mold groove 41, the material in the front feeding chute 2 will fall backward and the proximity switch 21 will receive a signal to control the front material to continue to be conveyed.
