Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coil processing, in particular to a shedding mechanism suitable for coil processing. Background Art
[0002] Ultra-thin and tiny hollow coils are light in weight, so they need to be placed on a plate during the production process. The existing processing method is often to first adsorb the coil through static electricity or vacuum adsorption, move it to the designated position through a mobile module, and then release the vacuum to make the coil fall. However, due to the static electricity and other characteristics of the coil itself, the hollow coil is often difficult to fall after being brought to the designated placement position by the fixture due to the static adsorption. At this time, an additional drop-assisting device is needed. The existing method usually involves installing an air blowing device to force the coil to fall to the designated position through air blowing. However, the existing air blowing device is sometimes difficult to control in terms of control accuracy, and the existence of electrostatic adsorption makes it difficult for the air blowing device to make the product fall off the fixture.

[0022] like Figure 1-3 As shown, a shedding mechanism suitable for coil processing includes a mounting seat 1, a nozzle cylinder 7 and a jig cylinder 8. The mounting seat 1 is connected to a bearing plate 13, the nozzle cylinder 7 is connected to the bearing plate 13, the jig cylinder 8 is arranged on one side of the nozzle cylinder 7 and is connected to the bearing plate 13, the output shaft of the jig cylinder 8 is connected to the jig 9, the output shaft of the nozzle cylinder 7 is equipped with a nozzle 12, and the jig 9 is provided with an avoidance slot 14, the jig 9 extends horizontally to the bottom of the nozzle cylinder 7, the nozzle 12 passes through the avoidance slot 14 of the jig 9, and there is a gap between the nozzle 12 and the inner wall of the avoidance slot 14. The nozzle 12 is used to adsorb the hollow coil 15, and the jig cylinder 8 drives the jig 9 to move up and down to press the hollow coil 15, so that when the adsorption is separated from the hollow coil 15, the nozzle can smoothly separate from the hollow coil, and the hollow coil is blocked by the jig, so that the nozzle is driven to move upward by the nozzle cylinder.
[0023] The mounting base 1 is provided with a rotating motor 2, the driving shaft of which is connected to the carrying plate 13. The rotating motor 2 is used to drive the carrying plate 13 to rotate, thereby driving the suction nozzle cylinder 7 and the fixture cylinder 8 to rotate synchronously, so that the suction nozzle 12 can rotate in a circle, and hollow coils in different orientations can be adsorbed and then placed at a designated position.
[0024] The output shaft of the jig cylinder 8 is equipped with a connecting block, and the jig 9 is locked and connected to the connecting block by screws, which facilitates the installation and disassembly of the jig, as well as the replacement, and increases compatibility.
[0025] The two sides of the avoidance groove 14 of the jig 9 are provided with lower extending side arms 10 for contacting the hollow coil 15, so that the jig 9 presents an inverted "L" shape structure. The lower extending side arms 10 are used to form a pressing effect on the hollow coil 15. The two lower extending side arms can form a larger contact area with the hollow coil, so that the coil can be subjected to uniform force and deformation caused by uneven force on the product can be prevented.
[0026] A fixing frame 3 is provided on the top of the supporting plate 13, and a fixing block 4 with a stroke groove 5 is installed on the fixing frame 3. The end of the driving shaft of the nozzle cylinder 7 extends out of the outside of the nozzle cylinder 7 and is installed with a limiting plate 6. The limiting plate 6 extends into the stroke groove 5. The upper surface and the lower surface of the stroke groove 5 form an upper moving stroke limit and a lower moving stroke limit for the limiting plate 6, which can make the movement of the nozzle more precise.
[0027] The suction nozzle 12 includes a cylinder 121 and an adsorption rod 122. The cylinder 121 is hollow inside. The upper end of the adsorption rod 122 is connected to the cylinder 121. An air cavity 123 is provided inside the adsorption rod 122. The air cavity 123 extends along the axial direction of the adsorption rod 122. The air cavity 123 extends to the lower end of the adsorption rod 122 and is connected to the outside. The side wall of the cylinder 121 is connected to the air pipe. Two air cavities are provided inside the adsorption rod 122, and a partition is provided between the two air cavities. The lower end of the adsorption rod 122 is provided with a protruding plug-in 124 for inserting a hollow coil. After the external air pipe is connected to the cylinder, air can be fed into or evacuated into the cylinder. When evacuating air, a vacuum is formed inside with adsorption force, which can adsorb the hollow coil. When air is supplied, the hollow coil can be blown off from the lower end of the adsorption rod. By setting two side-by-side air cavities, it is equivalent to adsorbing the hollow coil from both sides, forming a better adsorption force.
[0028] The protruding plug-in 124 and the adsorption rod 122 are an integrally formed structure and are directly processed and formed before leaving the factory.
[0029] refer to Figure 1As shown, the rotating motor 2 first drives the suction nozzle cylinder 7 and the suction nozzle 12 to rotate to the corresponding position, and then draws air from the inside of the suction nozzle 12 to form an adsorption force to adsorb the hollow coil 15. At this time, the hollow coil 15 is adsorbed by the suction nozzle 12, and then rotates again and the suction nozzle cylinder 7 drives the suction nozzle 12 to move downward to move the hollow coil 15 to the wobble plate 11. At this time, if air is blown directly into the suction nozzle, sometimes the hollow coil cannot be separated from the suction nozzle due to the electrostatic attraction of the hollow coil itself. Therefore, the present application sets a jig cylinder, and the jig cylinder drives the jig to move down to the hollow coil, and then presses the hollow coil. At this time, the suction nozzle cylinder drives the suction nozzle to move up and separate from the hollow coil, and then the jig cylinder drives the jig to move up and separate from the hollow coil. When the jig cylinder drives the jig to move down, the speed needs to be controlled. The speed cannot be too fast. If it is too fast, the hollow coil will be damaged or knocked away, and it will be out of the position where it is desired to be placed.
[0030] It should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
