Description

Technical Field

[0001] This utility model relates to a semi-automatic magnetic strip winding mechanism, belonging to the technical field of mechanical automation. Background Technology

[0002] Automated mechanical production technology is inextricably linked to systems engineering, computer technology, electronics, hydraulic and pneumatic technology, and automatic control technology. With the rapid development of industrial automation technology in my country and the increasing demands on automation technology, coupled with the growing national investment in artificial intelligence in recent years, the prevalence of industrial automation is gradually becoming a reflection of a nation's comprehensive strength.

[0003] Pressing a magnetic strip into a magnetic sleeve is a method for assembling magnetic components, primarily used in the production of electromagnetic devices such as brushless motors, external rotor motors, and transformers. The process involves first bending the magnetic strip into a circular structure to match the internal magnetic circuit path of the magnetic sleeve. The circularly wound magnetic strip is then mechanically pressed into the magnetic sleeve, significantly increasing the magnetic flux and improving component precision and anti-interference capabilities. However, currently, the process of pressing the magnetic strip into the magnetic sleeve still relies on manual winding, resulting in high labor costs. Furthermore, manual winding often leads to a high product defect rate, further increasing production costs. Therefore, a semi-automatic magnetic strip winding mechanism is urgently needed to address the problems mentioned in the background section. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the problems and shortcomings of existing technologies, the present invention aims to provide a semi-automatic magnetic strip winding mechanism. This mechanism uses a pusher cylinder to insert the magnetic strip into a guide cylinder for winding, and a lifting cylinder to push the wound magnetic strip into a magnetic sleeve. Simultaneously, a pressing cylinder and a pressing limit block prevent the magnetic strip and magnetic sleeve from falling off, thus saving labor costs and improving product yield. This solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a base plate and a magnetic strip. A propulsion cylinder is connected above the base plate. The propulsion cylinder is connected to a sliding plate via a transition plate and a transition block. The sliding plate is connected to a magnetic strip propulsion block. One end of the magnetic strip is abutted against the magnetic strip, and the other end of the magnetic strip corresponds to an opening on the side of a guide cylinder. The guide cylinder is connected above the base plate and has a magnetic strip lifting block inside. A magnetic sleeve is placed above the guide cylinder. A lifting cylinder is located below the base plate, and the output shaft of the lifting cylinder passes through the base plate and abuts against the magnetic strip lifting block.

[0007] Preferably, a magnetic guide seat is provided above the base plate, and the magnetic strip is engaged with the upper opening of the magnetic guide seat. The magnetic guide seat is connected to the top of the base plate, and the upper end of the magnetic guide seat has an opening for placing the magnetic strip. This ensures that when the magnetic strip pusher pushes the magnetic strip into the guide cylinder, the magnetic strip can be pushed stably and is less prone to shaking.

[0008] Preferably, a linear slider is slidably connected to the top of the base plate via a guide rail, and the linear slider is then connected to a sliding plate. The guide rail is connected above the base plate, and the linear slider is slidably connected on the guide rail. The sliding plate is connected above the linear slider. Because the linear slider can support and guide the moving parts to achieve high-precision linear motion, while bearing the load, reducing friction, and absorbing vibration, the magnetic strip can always maintain linear motion, thus allowing the magnetic strip to accurately extend into the guide cylinder.

[0009] Preferably, a cylinder mounting plate is connected to the base plate via a support column. A downward-pressing cylinder is mounted above the cylinder mounting plate, and the output shaft of the downward-pressing cylinder passes through the cylinder mounting plate to connect to a downward-pressing limiting block, aligning the downward-pressing limiting block with the magnetic sleeve. The cylinder mounting plate and support column are used for the stable installation of the downward-pressing cylinder, and the output shaft of the downward-pressing cylinder passes through the cylinder mounting plate to connect to the downward-pressing limiting block. When the downward-pressing cylinder is activated, its output shaft moves downward, causing the downward-pressing limiting block to abut against the magnetic sleeve. This secures the magnetic sleeve in a designated position, preventing the wound magnetic strip from pushing the magnetic sleeve off when it rises under the action of the lifting cylinder.

[0010] Preferably, a sensor corresponding to the magnetic strip can also be installed above the base plate. The sensor above the base plate is used to sense the position of the magnetic strip in real time. When it senses that the magnetic strip has been placed, it sends a signal to control the start of the push cylinder. When it senses that the magnetic strip has been fully pushed in, it sends a signal to control the lifting cylinder to lift the magnetic strip upward.

[0011] Preferably, the guide cylinder and magnetic stripe push block can be replaced according to different magnetic stripes. Replacement is simple: remove the existing guide cylinder from the base plate, remove the existing magnetic stripe push block from the sliding plate, and then install the new guide cylinder and magnetic stripe push block in the designated positions.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a simple structure and easy operation, enabling semi-automatic winding of a magnetic strip. Specifically, the magnetic strip pusher, driven by a pusher cylinder, first propels the magnetic strip forward through the opening of the guide cylinder. The magnetic strip winds along the inner wall of the guide cylinder until it is fully inside, completing the winding process. Then, a pressing cylinder descends, pushing a pressing limit block to fix the magnetic sleeve above the guide cylinder. Finally, a lifting cylinder pushes the wound magnetic strip upward along the inner wall of the guide cylinder, pushing the magnetic strip lifting block until the strip is fully inserted into the magnetic sleeve. The inclusion of a magnetic guide seat and a linear slider ensures stable pushing of the magnetic strip pusher, allowing the strip to accurately enter the guide cylinder. The pressing limit block prevents the magnetic strip from rising and pushing the magnetic sleeve out of the guide cylinder, thus preventing the strip and sleeve from detaching. Using this invention can greatly save the physical strength of R&D personnel, improve assembly efficiency, and at the same time improve product yield and reduce production costs.

Detailed Implementation

[0019] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0020] It should also be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0021] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] This embodiment provides a semi-automatic magnetic strip winding mechanism, such as... Figures 1 to 2 As shown: It includes a base plate 2 and a magnetic strip 1. A propulsion cylinder 5 is connected to the top of the base plate 2. The propulsion cylinder 5 is connected to a sliding plate 7 through an adapter plate and an adapter block. The sliding plate 7 is connected to a magnetic strip propulsion block 8. One end of the magnetic strip propulsion block 8 corresponds to and abuts against the magnetic strip 1. The other end of the magnetic strip 1 corresponds to the opening on the side of the guide cylinder 13. The guide cylinder 13 is connected to the top of the base plate 2 and has a magnetic strip lifting block inside. A magnetic sleeve 15 is placed on the top of the guide cylinder 13. A lifting cylinder 4 is provided below the base plate 2. The output shaft of the lifting cylinder 4 passes through the base plate 2 and abuts against the magnetic strip lifting block.

[0023] This embodiment also includes a magnetic guide seat 14 above the base plate 2, with the magnetic strip 1 engaged at the opening of the magnetic guide seat 14. A linear slider is slidably connected above the base plate 2 via a guide rail 6, and the linear slider is then connected to a sliding plate 7. Placing the magnetic strip 1 at the opening of the magnetic guide seat 14 ensures that the magnetic strip 1 is stably pushed by the magnetic strip pusher block 8 when it pushes the magnetic strip 1 into the guide cylinder 13, preventing it from wobbling. The linear slider is slidably connected on the guide rail 6, and the sliding plate 7 is connected above the linear slider. This ensures that the magnetic strip 1 always moves in a straight line, allowing it to accurately extend into the guide cylinder 13.

[0024] This embodiment also includes a cylinder mounting plate 10 connected to the top of the base plate 2 via a support column 9. A pressing cylinder 3 is mounted above the cylinder mounting plate 10, and the output shaft of the pressing cylinder 3 passes through the cylinder mounting plate 10 and connects to a pressing limit block 11, aligning the pressing limit block 11 with the magnetic sleeve 15. The cylinder mounting plate 10 and the support column 9 are used for the stable installation of the pressing cylinder 3, and the output shaft of the pressing cylinder 3 passes through the cylinder mounting plate 10 and connects to the pressing limit block 11. When the pressing cylinder is activated, its output shaft moves downward, causing the pressing limit block 11 to abut against the magnetic sleeve 15. This is to fix the magnetic sleeve 15 in a designated position and prevent the magnetic sleeve 15 from falling out when the wound magnetic strip 1 rises under the action of the lifting cylinder 4.

[0025] This embodiment also includes a sensor (not shown in the attached diagram) corresponding to the magnetic strip 1, which can be installed above the base plate 2. The guide cylinder 13 and the magnetic strip pusher block 8 can be replaced according to different sizes of magnetic strips 1. The sensor above the base plate 2 is used to sense the position of the magnetic strip in real time. When it senses that the magnetic strip 1 has been placed, it sends a signal to control the start of the push cylinder. When it senses that the magnetic strip has been fully pushed in, it sends a signal to control the lifting cylinder to lift the magnetic strip upward. When replacing the guide cylinder 13 and the magnetic strip pusher block 8, it is only necessary to remove the existing guide cylinder 13 from the base plate 2, remove the existing magnetic strip pusher block 8 from the sliding plate 7, and then install the new guide cylinder 13 and magnetic strip pusher block 8 to be replaced in the designated position.

[0026] Method of using this utility model

[0027] The connection of this utility model includes a base plate 2 and a pressing cylinder 3, a lifting cylinder 4, and a pushing cylinder 5 connected thereto. Specifically, the lifting cylinder 4 is connected below the base plate 2, and the output shaft of the lifting cylinder 4 passes through the base plate 2 and extends into the interior of the guide cylinder 13. A magnetic strip lifting block (not shown in the drawings) is provided inside the guide cylinder 13, and the magnetic strip lifting block is connected to the output shaft of the lifting cylinder 4. The guide cylinder 13 is connected above the base plate 2 and has an opening on its side. The pushing cylinder 5 is connected above the base plate 2 via a cylinder support 12, and a sliding plate 7 is connected above the pushing cylinder 5 via an adapter plate and an adapter block. In particular, a guide rail 6 is also provided above the base plate 2, and a linear slider is slidably connected above the guide rail 6 and then connected to the sliding plate 7. A magnetic strip pushing block 8 is connected below the sliding plate 7. A magnetic guide seat 14 is connected above the base plate 2, and the magnetic strip 1 passes through the magnetic guide seat 14. One end of the magnetic stripe pusher block 8 corresponds to one end of the magnetic stripe 1, and the other end of the magnetic stripe 1 corresponds to the opening of the guide cylinder 13. A cylinder mounting plate 10 is connected to the top of the base plate 2 via a support column 9, and a pressing cylinder 3 is mounted above the cylinder mounting plate 10. The output shaft of the pressing cylinder 3 passes through the cylinder mounting plate 10 and connects to the pressing limit block 11. The upper end of the guide cylinder 13 is connected to a magnetic sleeve 15, and the pressing limit block 11 and the magnetic sleeve 15 abut against each other.

[0028] During the initial preparation phase, the R&D personnel need to prepare the magnetic strip 1. Since it is a device that winds a single magnetic strip in a circle, only one magnetic strip needs to be prepared at a time. After confirming that the device is powered on and pneumatically supplied, perform a pneumatic compression test once without inserting the magnetic strip. Then, adjust the strokes of the pressing cylinder 3, lifting cylinder 4, and pushing cylinder 5 to the required values. Because the magnetic strips vary in length, the guide cylinder 13 needs to be selected according to the different magnetic strips 1. The length of the magnetic strip pushing block 8 determines the depth to which the magnetic strip 1 enters. Therefore, the size of the magnetic strip pushing block 8 is not uniform, and the R&D personnel need to select the corresponding magnetic strip pushing block 8 and guide cylinder 13 according to the actual magnetic strip size.

[0029] During operation, the R&D personnel place the magnetic strip 1 in the magnetic guide seat 14 and ensure that the magnetic strip 1 is fully matched with the magnetic strip pusher block 8 and the guide cylinder 13, while the cylinder stroke is adjusted. Pressing the start switch initiates the process. First, the magnetic strip pusher block 8, driven by the pusher cylinder 5, pushes the magnetic strip 1 forward through the opening of the guide cylinder 13. The magnetic strip 1 circles along the inner wall of the guide cylinder 13 until it is fully inside, completing its circuitry. Then, the pressing cylinder 3 descends, pushing the pressing limit block 11 against the magnetic guide sleeve 15, thus fixing the magnetic guide sleeve 15 above the guide cylinder 13. Finally, the lifting cylinder 4 pushes the circled magnetic strip 1 upwards along the inner wall of the guide cylinder 13, pushing the magnetic strip lifting block until the magnetic strip 1 is fully inserted into the magnetic guide sleeve 15. During the process of the magnetic strip lifting block pushing the magnetic strip 1, the downward limiting block 11 can be used to prevent the magnetic strip 1 from rising and pushing the magnetic sleeve 15 out of the guide cylinder 13, which would eventually cause the magnetic strip 1 and the magnetic sleeve 15 to fall off.

[0030] After verification, the draft angle of the inner wall of the magnetic sleeve 15 is 5°, and the magnetic strip 1 will not be damaged at this angle.
