Description

Technical Field

[0001] This invention relates to the field of ferrite core stacking equipment, and in particular to a ferrite core packaging and stacking device. Background Technology

[0002] Ferrite cores are made of dense, homogeneous, ceramic-structured non-metallic magnetic materials. They have low coercivity and are also known as soft magnetic ferrite cores. Inductors or transformers can be made by winding coils around ferrite cores, and these are widely used in instruments, communication equipment, and household appliances. There are many types of ferrite cores. One commonly used core in Hall current sensors is a circular magnetic ring with an opening, around which a coil is wound to form an inductance. The opening in the core is also called an air gap. The presence of the air gap reduces permeability, increases saturation current, increases energy storage capacity, and reduces remanence.

[0003] Because the ferrite core's position and opening orientation are fixed within a Hall current sensor, some Hall current sensor manufacturers require us to fix the ferrite core openings during production and packaging to facilitate automated production and improve efficiency. To meet these requirements, we currently manually clip each ferrite core onto the protrusions on a tray, resulting in low packaging efficiency. With increasing automation in Hall current sensor production, more and more customers are requesting fixed ferrite core opening placement. To better serve our customers, we have developed a ferrite core packaging and stacking device. Summary of the Invention

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Example

[0025] like Figure 1 As shown, this invention discloses a ferrite core packaging and stacking device, including a support frame 100, a support platform 200, a tray 300, a material assembly assembly 400, a counting assembly 500, a feeding assembly 600, and a pushing assembly 700. The tray 300 is placed on the support platform 200, which supports and positions the tray 300. The material assembly assembly 400 is disposed on the top wall of the support frame 100, the counting assembly 500 is disposed on the side wall of the support frame 100, the feeding assembly 600 is disposed on two parallel side walls of the support frame 100, and the pushing assembly 700 is disposed on the bottom wall of the support frame 100. The pushing assembly 700 is used to push the ferrite cores on the feeding assembly 600 toward the tray 300. The material sorting assembly 400 sorts the magnetic cores (ferrite cores, hereinafter referred to as cores). The sorted cores fall onto the feeding assembly 600. During the falling process, the counting assembly 500 counts the falling cores. When the number reaches a specified quantity (the production time specified quantity is 50), the counting assembly 500 limits the feeding process. The feeding assembly 600 then conveys the cores towards the tray 300, and the pushing assembly 700 pushes the cores from the feeding assembly 600 onto the tray 300. The material sorting assembly 400 achieves automatic sorting of the magnetic cores, eliminating the need for manual sorting one by one, improving the sorting efficiency, and reducing the labor intensity of workers.

[0026] like Figure 2-3As shown, the material sorting assembly 400 includes a sorting tray 401 and a sorting cylinder 402. The sorting cylinder 402 is fixedly connected to the lower end face of the sorting tray 401. The sorting cylinder 402 is fixedly connected to the support frame 100, and the lower end of the sorting cylinder 402 passes through the top wall of the support frame 100. Two sets of sorting cylinders 402 are arranged in parallel. A first through-ring rod 403 is coaxially arranged in the inner cavity of the sorting cylinder 402. A connecting strip 404 is fixedly connected between the first through-ring rod 403 and the inner side wall of the sorting cylinder 402. A material discharge port 405 communicating with the sorting cylinder 402 is opened on the bottom wall of the sorting tray 401. The magnetic core in the sorting tray 401 falls into the sorting cylinder 402 through the material discharge port 405. The sorting disc 401 is coaxially rotatably connected to a synchronous shaft 406. An arc-shaped push rod 407 is fixedly connected to the upper end of the synchronous shaft 406, and an adjusting disc 408 is fixedly connected to the lower end of the synchronous shaft 406. The adjusting disc 408 is located between two sorting cylinders 402. An adjusting port 409 is opened on the side wall of the sorting cylinder 402. The adjusting disc 408 is rotatably connected to the two adjusting ports 409. The lower end face of the adjusting disc 408 is flush with the upper end face of the first through-ring rod 403. A drive motor 410 is fixedly connected to the lower end face of the sorting disc 401. A drive gear 411 is fixedly connected to the output shaft of the drive motor 410. A driven gear 412 is fixedly connected to the synchronous shaft 406, and the driven gear 412 meshes with the drive gear 411. The drive motor 410 simultaneously drives the push rod 407 and the adjusting plate 408 to rotate. The rotation of the push rod 407 pushes the magnetic core in the sorting plate 401 into the inner cavity of the sorting cylinder 402 and onto the upper end face of the first ring rod 403. The rotation of the adjusting plate 408 drives the magnetic core onto the upper end face of the first ring rod 403 to rotate. When the opening of the magnetic core is aligned with the connecting strip 404 on the side wall of the first ring rod 403, the magnetic core is fitted onto the first ring rod 403 under the action of gravity. Guided by the first ring rod 403, the magnetic core falls onto the feeding assembly 600. The counting assembly 500 counts the magnetic cores falling onto the feeding assembly 600. When the number reaches 50, the counting assembly 500 blocks the lower end of the sorting cylinder 402 to prevent the magnetic core from falling further.

[0027] like Figure 4 As shown, the counting assembly 500 includes a baffle ring 501, a baffle cylinder 502, and a counting sensor 503. The cylinder body of the baffle cylinder 502 is fixedly connected to the outer wall of the support frame 100, and the piston rod of the baffle cylinder 502 passes through the side wall of the support frame 100. The baffle ring 501 is fixedly connected to the piston rod of the baffle cylinder 502 and is coaxially arranged with the sorting cylinder 402. The counting sensor 503 is fixedly connected to the inner wall of the baffle ring 501. The magnetic core passes through the baffle ring 501 and falls onto the feeding assembly 600. The counting sensor 503 counts the falling magnetic cores. When the number of falling magnetic cores reaches 50, the piston rod of the baffle cylinder 502 expands, pushing the baffle ring 501 to misalign with the sorting cylinder 402 to prevent the magnetic core from falling further.

[0028] like Figure 5 As shown, the feeding assembly 600 includes a rotary shaft 601 and a servo motor 602. The rotary shaft 601 is rotatably connected between two parallel side walls of the support frame 100. The servo motor 602 is fixedly connected to the outer side wall of the support frame 100. The main shaft of the servo motor 602 is fixedly connected to the rotary shaft 601. A second through-ring rod 603 is fixedly connected to the side wall of the rotary shaft 601. Four sets of second through-ring rods 603 are equally spaced along the circumference of the rotary shaft 601. A positioning strip 604 is fixedly connected to the outer side wall of the second through-ring rod 603. The second through-ring rods 603 are respectively located at both ends of the rotary shaft. When the second through-ring rod 603 is coaxial with the first through-ring rod 403, the positioning strip 604 is located below the connecting strip 404. An arc-shaped retaining ring 605 is fixedly connected to one end of the second through-ring rod 603 near the rotary shaft 601. The retaining ring 605 is coaxial with the second through-ring rod 603. When the second ring rod 603 rotates below the first ring rod 403, the piston rod of the stop cylinder 502 resets, and the magnetic core on the first ring rod 403 falls onto the second ring rod 603. The positioning strip 604 aligns with the opening of the magnetic core, and the retaining ring 605 at the end of the second ring rod 603 near the rotating shaft 601 blocks the magnetic core. When the counting sensor 503 counts to 50, the magnetic core stops falling, and the servo motor 602 drives the rotating shaft 601 to rotate 90 degrees, rotating the second ring rod 603 with the magnetic core towards the tray 300.

[0029] like Figure 6 As shown, the feeding assembly 700 includes a support plate 701, a slider 702, a feeding cylinder 703, a double-headed cylinder 704, and claws 705. The support plate 701 is fixedly connected to the bottom wall of the support frame 100 and is located between two parallel side walls of the support frame 100. A sliding groove 706 is provided on the upper surface of the support plate 701. The slider 702 is slidably connected in the sliding groove 706. The feeding cylinder 703 is fixedly connected to the end of the sliding groove 706 away from the support platform 200. The piston rod of the feeding cylinder 703 is fixedly connected to the slider 702. The cylinder body of the double-headed cylinder 704 is fixedly connected to the slider 702. Two sets of claws 705 are provided and are respectively fixedly connected to the moving rods at both ends of the double-headed cylinder 704. The claws 705 are arc-shaped. When the rotating shaft 601 with the magnetic core rotates to face the tray 300, the two moving rods of the double-headed cylinder 704 move away from each other, pushing the pawl 705 to lock onto the second through-ring rod 603. The piston rod of the pushing cylinder 703 extends, and the pawl 705 pushes the magnetic core on the second through-ring rod 603 toward the tray 300.

[0030] The retaining ring 605 and the push claw 705 are both arc-shaped to prevent interference between the push claw 705 and the retaining ring 605 when the push claw 705 pushes the magnetic core off the second ring rod 603.

[0031] like Figure 7-8 As shown, the tray 300 includes a base 301, a baffle 302, and a corrugated plate 303. The baffle 302 is fixedly connected to the upper surface of the base 301. The baffle 302 is U-shaped, with its opening facing the support frame 100. The corrugated plate 303 is fixedly connected between two parallel sections of the baffle 302. The corrugated plate 303 has eight equally spaced grooves 304 for placing magnetic cores. Magnetic core positioning strips 305 are fixedly connected to the grooves 304. When a magnetic core is pushed onto the tray 300, it moves along the magnetic core positioning strips 305. After the magnetic core is in place, it is neatly secured on the magnetic core positioning strips 305, making it convenient for customers to retrieve. To prevent the tray 300 from moving along with the magnetic core as it moves along the magnetic core positioning strip 305, a U-shaped positioning protrusion 306 is fixedly connected to the lower end face of the chassis 301. The opening of the positioning protrusion 306 faces the support frame 100. The upper end face of the support platform 200 has a positioning groove 201 that matches the positioning protrusion 306. The positioning protrusion 306 is engaged in the positioning groove 201. There are four sets of positioning grooves 201 at equal intervals. The pushing component 700 pushes the magnetic core into two sets of grooves 304 in one pushing action. After the operator adjusts the position of the tray 300, the pushing component 700 pushes the magnetic core into the grooves 304 again until the grooves 304 in the tray 300 are full of magnetic cores. Then, the next tray 300 is used to place the magnetic cores. Figure 8 The positioning groove 201 and the magnetic core positioning strip 305 are numbered respectively. The positioning groove 201 is numbered with the same number for the two parallel U-shaped grooves, for example: number ①. The magnetic core positioning strip 305 is numbered sequentially as (1), (2)...(8). During operation, the positioning protrusion 306 is first placed in the groove ① 304. The pushing component 700 pushes the magnetic core on the feeding component 600 into the magnetic core positioning strips (1) and (5) at the same time. After the magnetic core is pushed in, the tray is moved and the positioning protrusion 306 is placed in the groove ② 304. The pushing component 700 pushes the magnetic core on the feeding component 600 into the magnetic core positioning strips (2) and (6) at the same time. After the magnetic core is pushed in, the tray is moved. Place the positioning protrusion 306 in the groove 304. The pushing component 700 pushes the magnetic core on the feeding component 600 into the magnetic core positioning strips 305 of (3) and (7) at the same time. After the magnetic core is pushed in, move the tray and place the positioning protrusion 306 in the groove 304 of (4). The pushing component 700 pushes the magnetic core on the feeding component 600 into the magnetic core positioning strips 305 of (4) and (8) at the same time. After the magnetic core is pushed in, remove the tray.

[0032] In this application, the operation of each electronic component is connected by a PLC controller. The connection process has been disclosed in the above application and will not be repeated here.
