Description

Technical Field

[0001] The invention relates to the technical field of automation equipment, and in particular to a arranging and feeding device for inductor coils. Background Art

[0002] An inductor is an electronic component made of wound wire, usually wound around a magnetic core or non-magnetic core material. Its main characteristics are the ability to store magnetic energy and resist changes in current. It is widely used in power supply and signal transmission, wireless communication, voltage transformation and filtering.

[0003] After production, the inductor coils are in bulk state. In order to facilitate customer use and packaging for shipment, the inductor coils need to be sorted. The existing method is generally to put the inductor coils into a vibration plate first, and the vibration plate will initially disperse and transport the disordered inductor coils through vibration; then, the inductor coils enter the limiting and blocking module, which limits and guides the coils to ensure that the coils are output in a specific posture (such as forward, flat, etc.) to facilitate subsequent arrangement, clamping and feeding operations.

[0004] In the process of sorting and feeding inductor coils, the traditional method relies on a vibrating plate to disperse the coils and combines visual recognition equipment to detect the front and back sides and grab them. This method is prone to entanglement and accumulation when processing large quantities of long coils, seriously affecting the dispersion efficiency. On high-speed production lines, visual recognition equipment has deficiencies in real-time and accuracy, making it difficult to quickly and accurately identify the front and back sides of the inductor coils, resulting in frequent grabbing errors and the production line needs to be frequently shut down for adjustments.

[0005] Based on the above situation, the present invention proposes a arranging and feeding device for inductor coils. Summary of the invention

DETAILED DESCRIPTION

[0032] The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0033] Embodiment 1: A feeding device for arranging inductor coils, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes a material rack 1, a vibrating material tray 2 is slidably connected to the left side of the material rack 1, the vibrating material tray 2 is flush with the height of the material rack 1, the vibrating material tray 2 and the material rack 1 are both provided with evenly distributed grooves, a plurality of coils 101 are placed on the vibrating material tray 2, two first springs 3 symmetrically distributed front and back are connected between the vibrating material tray 2 and the material rack 1, a first piston frame 301 is fixedly connected to the middle of the material rack 1, a material guide frame 4 is movably connected to the first piston frame 301, and a guide frame 4 is movably connected to the guide frame 4. Five evenly distributed material guide rods 5 are threadedly connected to the material rack 4, a rotating rack 6 is sleeved on the first piston rack 301, the rotating rack 6 is fixedly connected to the material guide rack 4, five holes are opened on the rotating rack 6, and the material guide rods 5 pass through the adjacent holes, a second piston rack 7 is fixedly connected to the middle of the front side of the material rack 1, a rack rack 8 is slidably connected in the second piston rack 7, a gear is provided on the rotating rack 6, the gear and the rack rack 8 are meshed with each other, and gas injection ports are provided at the ends of the first piston rack 301 and the second piston rack 7.

[0034] like Figure 5 and Figure 6As shown, it also includes a fixing mechanism for clamping the coil 101 strung on the guide rod 5, the fixing mechanism is arranged on the guide rod 5, the fixing mechanism includes a guide magnetic rod 9, five guide magnetic rods 9 are respectively slidably connected in the guide rod 5, a second spring 12 is connected between the front part of the guide magnetic rod 9 and the adjacent guide rod 5, each second spring 12 is wound around the adjacent guide magnetic rod 9, each guide magnetic rod 9 is provided with symmetrically distributed oblique through holes, and a clamping frame 10 is slidably connected between the oblique through holes in the horizontal direction, the number of the first magnetic blocks 11 is five, each guide rod 5 is respectively fixed with a first magnetic block 11, the first magnetic block 11 and the adjacent guide magnetic rod 9 are magnetically matched, the rear end of the groove in the material rack 1 is fixed with a second magnetic block 13, and the second magnetic block 13 and the guide magnetic rod 9 are magnetically matched.

[0035] like Fig.10 and Fig.11 As shown, it also includes a blocking mechanism for blocking the second magnetic block 13 to prevent the bracket 10 from releasing the fixed coil 101 too early. The blocking mechanism is arranged on the material rack 1, and the blocking mechanism includes a blocking frame 21. The blocking frame 21 is vertically slidably connected to the rear side of the material rack 1, and the inner side of the blocking frame 21 is provided with evenly distributed inclined surfaces.

[0036] Initially, the material guide frame 4 is in a state of extending from the first piston frame 301. The bulk coils 101 can be poured onto the vibrating tray 2 first, and the vibrating tray 2 will drive the coils 101 to vibrate together, so that the coils 101 falling into the grooves of the vibrating tray 2 can be arranged in an orderly manner in a long row, similar to material sorting, which provides convenience for subsequent processing. Secondly, the air inside is extracted through the air injection port of the first piston frame 301, similar to the working principle of an air pump. Under the action of the airflow, the material guide frame 4 and the material guide rod 5 move backwards accordingly, and the backward moving material guide rod 5 will string together the coils 101 arranged in the grooves to prepare for subsequent material transfer.

[0037] When the guide magnetic rod 9 in the guide rod 5 contacts the inner rear wall of the vibrating material tray 2, the inner rear wall of the vibrating material tray 2 will press against the guide magnetic rod 9 to make it move forward until it contacts the first magnetic block 11, the second spring 12 is compressed, and under the action of the magnetic force, the first magnetic block 11 will attract the guide magnetic rod 9. At the same time, the guide magnetic rod 9 will drive the clamping frame 10 to move outward to clamp the coil 101 sleeved on the guide rod 5, so that the coil 101 strung on the guide rod 5 is fixed, and then gas can be introduced inward through the gas injection port of the second piston frame 7 to move the rack frame 8 to the left. Since the rack frame 8 is meshed with the gear on the rotating frame 6, the rotating frame 6 is driven to rotate clockwise, thereby driving the guide frame 4, the guide rod 5 and the strung coil 101 to flip 180° to the right, and the guide rod 5 will drive the coil 101 to flip into the groove of the material rack 1.

[0038] When the guide magnetic rod 9 in the guide rod 5 is aligned with the second magnetic block 13, under the magnetic force of the second magnetic block 13, the second magnetic block 13 will suck the guide magnetic rod 9 outward, causing it to move backward to separate from the first magnetic block 11, and the guide magnetic rod 9 will contact the inclined surface of the baffle 21 and push it upward, and cause the bracket 10 to move inward to release the coil 101, and the second spring 12 will restore its original length, and then gas will be introduced into the gas injection port of the first piston frame 301, and the guide frame 4 will drive the guide rod 5 to move forward, so that the coil 101 strung on the guide rod 5 will retreat into the groove of the material rack 1, and the baffle 21 will slide downward and reset under its own gravity, and continue to block the front side of the second magnetic block 13.

[0039] Finally, the gas in the second piston frame 7 is extracted to move the rack frame 8 to the right, and the guide frame 4 and the guide rod 5 are driven to flip to the left to the initial position through the rotating frame 6 to prepare for the next material processing process. In summary, the coils 101 arranged in the grooves of the vibrating material tray 2 are first strung together by the guide frame 4 and the guide rod 5 to improve the material sorting speed. Secondly, the coils 101 are fixed by the clamping frame 10 to ensure that the coils 101 will not fall off or shift during the subsequent processing, providing a stable basis for the flipping and placement of the coils 101. Then, the rack frame 8 and the rotating frame 6 cooperate with each other to neatly place the strung coils 101 in the grooves of the material rack 1, ensuring that the coils 101 can be neatly placed in the predetermined order and position. The whole process combines a variety of technical means such as mechanical clamping, pneumatic control, and transmission flipping to achieve automatic processing and positioning of materials.

[0040] Embodiment 2: Based on embodiment 1, Figure 8 and Fig. 9 As shown, it also includes a locking mechanism for keeping the vibration material tray 2 stable when the guide rod 5 takes the coil 101 in series. The locking mechanism is arranged on the material rack 1, and the locking mechanism includes a locking frame 18. The locking frame 18 is slidably connected to the front right part of the material rack 1. Two fourth springs 19 are connected between the locking frame 18 and the material rack 1. The two fourth springs 19 are both wound on the locking frame 18. The front side of the top wall of the vibration material tray 2 is slidably connected with left-right symmetrically distributed pressure rods 20. The bottoms of the two pressure rods 20 are in contact with the locking frame 18. The pressure rods 20 are squeezed and matched with the locking frame 18. A bayonet is opened on the locking frame 18, and the locking frame 18 is engaged with the material rack 1.

[0041] When the guide rod 5 is stringing the coil 101, if the vibrating material tray 2 is still vibrating up and down, the coil 101 in the groove will also shake, making it inconvenient for the guide rod 5 to string it together. The specific operation is as follows: when the guide rod 5 moves backward to string the coil 101 together, the guide rod 5 will press the pressure rod 20 downward, and the pressure rod 20 will slide downward slightly and squeeze the positioning frame 18, so that the positioning frame 18 moves forward and is stuck on the material rack 1, and the fourth spring 19 is deformed, and the positioning frame 18 that is stuck on the material rack 1 will firmly support the vibrating material tray 2, so that the vibrating material tray 2 remains in a stable state, thereby facilitating the guide rod 5 to string the coil 101 together.

[0042] When the guide rod 5 drives the coil 101 to flip to the right, the guide rod 5 is no longer pressed on the pressure rod 20, and under the elastic force of the fourth spring 19, the positioning frame 18 will slide forward and release the lock on the vibration material tray 2, and the pressure rod 20 will also slide upward and reset. In summary, through the cooperation of the guide rod 5, the pressure rod 20, the positioning frame 18, etc., it is ensured that the vibration source can be effectively stabilized when the coil 101 is strung together, the efficiency and accuracy of material sorting are improved, thereby optimizing the entire material processing process.

[0043] like Figure 7 As shown, it also includes a shaking mechanism for shaking off the brought-out coil 101, the shaking mechanism is arranged on the guide frame 4, the shaking mechanism includes a guide plate 14, the guide plate 14 is slidably connected to the guide frame 4, and a third spring 15 symmetrically distributed on the left and right is connected between the guide plate 14 and the guide frame 4, and the two third springs 15 are both wound around the guide frame 4, and the guide plate 14 is provided with evenly distributed circular holes, and the guide plate 14 is sleeved on the five guide rods 5 through the circular holes, the left and right parts of the front side of the guide frame 4 are fixedly connected with an electromagnet 16, and the left and right parts of the rear side of the guide plate 14 are fixedly connected with a third magnetic block 17, and the electromagnet 16 and the adjacent third magnetic block 17 are magnetically matched.

[0044] When the guide rod 5 drives the coil 101 to flip to the right, if there are a small number of scattered coils 101 hanging on the guide rod 5, in order to avoid bringing these scattered coils 101 to the material rack 1 and affecting the material sorting, the specific operation is as follows: when the guide rod 5 drives the coil 101 to flip to the right, the electromagnet 16 can be controlled to continuously power on and off. When the electromagnet 16 is energized, under the action of electromagnetic force, the electromagnet 16 will suck the third magnetic block 17 backwards, so that the third magnetic block 17 drives the guide plate 14 and the guide rod 5 to move backwards, and the third spring 15 will be deformed. Since the guide rod 5 is threadedly connected to the guide rack 4, the guide rod 5 will rotate and move backwards, which helps to shake off the scattered coils 101 hanging on the guide rod 5.

[0045] Similarly, when the electromagnet 16 is powered off, under the elastic force of the third spring 15, the guide rod 5 rotates and moves forward. As the electromagnet 16 is continuously powered on and off, the guide rod 5 will continue to move back and forth and rotate. This shaking will effectively shake off the bulk coils 101 hanging on the guide rod 5. In summary, by cleverly utilizing the cooperation of components such as the electromagnet 16, the third magnetic block 17, and the guide plate 14, and controlling the power on and off operations of the electromagnet 16, the bulk coils 101 hanging on the guide rod 5 can be effectively shaken off, thereby ensuring smooth material sorting.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
