Description

Technical Field

[0001] This application relates to the field of magnetic device manufacturing technology, specifically to a coating device. Background Technology

[0002] Magnetic devices mainly consist of a coil and a magnetic core. The coil is wound around the outside of the magnetic core, and both the coil surface and the magnetic core surface are usually coated with an insulating layer. Metal terminals are located at both ends of the coil's conductor. Currently, to ensure the coil conductor is completely encased in the metal terminals, a metal terminal bending device is typically used. However, existing metal terminal bending devices only have a pressing mechanism, resulting in a loose fit between the metal terminal and the conductor. This leads to poor electrical connection between the metal terminal and the conductor during subsequent soldering processes, ultimately affecting the reliability of the magnetic device.

[0028] This application provides a coating device for coating wires onto metal terminals, including a side-pushing mechanism and a pressing mechanism. The side-pushing mechanism has a first side-pushing component and a second side-pushing component, which are respectively located on opposite sides of a magnetic device. The pressing mechanism has a pressing component, which is located above the magnetic device. The first side-pushing component and the second side-pushing component are used to apply a pushing force from the side of the magnetic device to coat the wires onto the metal terminals of the magnetic device.

Simultaneously, after the magnetic device is pressed by the side-pushing mechanism, the pressing component applies a pushing force from above the magnetic device to press the metal terminal and the wire together, changing the snap-fit ​​structure from a D-shaped to an O-shaped structure. In other words, through the combined action of the side-pushing mechanism and the pressing mechanism, the metal terminal and the wire can be tightly fitted together.

This application provides a covering device 10 for covering a metal terminal 22 with a wire 24, including a side-pushing mechanism 100 and a pressing mechanism 200. The side-pushing mechanism 100 has a first side-pushing component 110 and a second side-pushing component 120, which are respectively located on opposite sides of the magnetic device 20. The pressing mechanism 200 has a pressing component, which is located above the magnetic device 20. The first side-pushing component 110 and the second side-pushing component 120 are used to apply a pushing force from the side of the magnetic device to cover the wire 24 with the metal terminal 22 of the magnetic device 20. The pressing component is used to apply a pushing force from above the magnetic device after the magnetic device 20 has been pressed by the side-pushing mechanism 100 to press the metal terminal 22 and the wire 24 together. Specifically, the covering device 10 provided in this application is used to bend the metal terminal 22 to cover the beginning and end of the wire 24. The magnetic device 20 has a coil, a winding post, a magnetic plate 21, and a metal terminal 22. Both ends of the winding post are connected to the magnetic plate 21. Metal terminals 22 are provided on both sides of the magnetic plate 21. The metal terminal 22 has a snap-fit ​​structure 23. Before being bent by the covering device 10, the snap-fit ​​structure 23 is U-shaped. After being bent by the covering device 10, the outer side of the snap-fit ​​structure 23... The outer edge is bent towards the inner edge to form an O-shaped structure, and the coil is wound on the winding post; the covering device 10 includes a side pushing mechanism 100, a pressing mechanism 200, a carrier plate 300, and a side pushing plate 400. The side pushing plate 400 is connected to the upper surface of the carrier plate 300. The side of the side pushing plate 400 facing away from the carrier plate 300 is connected to the side pushing mechanism 100, and the side of the side pushing plate 400 is connected to the pressing mechanism 200. The side pushing plate 400 is connected to the carrier plate 300, to the side pushing mechanism 100, and to the side pushing mechanism 200. The pressing mechanisms 200 can be connected by threads, welding, or adhesive bonding; the first side push assembly 110 and the second side push assembly 120 are respectively located on the outer side of the snap-fit ​​structure 23, that is, the first side push assembly 110 and the second side push assembly 120 are respectively located on opposite sides of the magnetic device 20; it should be noted that the outer side of the snap-fit ​​structure 23 refers to the side of the snap-fit ​​structure 23 opposite to the pressure head 114; the pressing components of the pressing mechanism 200 are located above the magnetic device 20, and the first side push assembly 110 and the second side push assembly 120 are respectively located on opposite sides of the magnetic device 20. Component 120 is used to apply a pushing force from the outer side of the magnetic device to change the shape of the snap-fit ​​structure 23 from a U-shaped to a D-shaped structure, thereby making the metal terminal 22 of the magnetic device 20 cover the wire 24. The pressing component is used to apply a pushing force from above the magnetic device after the magnetic device 20 has been pressed by the side-pushing mechanism 100 to press the metal terminal 22 and the wire 24 together, so that the shape of the snap-fit ​​structure 23 changes from a D-shaped to an O-shaped structure, so that the metal terminal 22 and the wire 24 are tightly attached.

[0031] In this application, the covering device 10 is composed of a pressing mechanism 200 and a side-pushing mechanism 100, with the first side-pushing assembly 110 and the second side-pushing assembly 120 both disposed below the pressing assembly. This allows the shape of the snap-fit ​​structure 23 of the metal terminal 22 to change from a U-shaped to a D-shaped structure after the first side-pushing assembly 110 and the second side-pushing assembly 120 apply a pushing force from the outer side of the magnetic device, thus covering the wire 24 with the metal terminal 22 of the magnetic device 20. Simultaneously, after the magnetic device 20 is pressed by the side-pushing mechanism 100, the pressing assembly applies a pushing force from above the magnetic device to press the metal terminal 22 and the wire 24 together, changing the shape of the snap-fit ​​structure 23 from a D-shaped to an O-shaped structure. This is achieved through the side-pushing mechanism 100 and the pressing assembly... The combined effect of the structure 200 allows the metal terminal 22 and the wire 24 to fit tightly together, preventing poor electrical connection between the metal terminal 22 and the wire 24 in subsequent soldering processes. This improves the reliability and efficiency of the metal terminal 22 covering the wire 24, while reducing costs. Furthermore, the covering device 10 of this application is composed of a pressing mechanism 200 and a side-pushing mechanism 100, with the first side-pushing component 110 and the second side-pushing component 120 both located below the pressing component. This makes the covering device 10 suitable for covering the beginning and end of thick wire coils with the metal terminal 22, especially for covering wires 24 with a diameter of 0.03 mm or more, ensuring that the thick wire 24 is tightly covered by the metal terminal 22, thus improving product reliability.

[0032] In one embodiment, both the first side-push assembly 110 and the second side-push assembly 120 include a moving assembly and a side-pressing assembly connected to the moving assembly. The side-pressing assembly is located on the side of the magnetic device 20 and can drive the moving assembly to move so that the side-pressing assembly can press the metal terminal 22 so that the metal terminal 22 covers the wire 24. Specifically, both the first side-pushing assembly 110 and the second side-pushing assembly 120 include a moving assembly and a side-pressing assembly connected to the moving assembly. The moving assembly includes a moving plate 111 and a sliding plate 112. The sliding plate 112 is fixedly connected to the inner side of the moving plate 111. The sliding plate 112 and the moving plate 111 are located on the top and bottom sides of the magnetic device 20, that is, the sliding plate 112 and the moving plate 111 are located on the two magnetic plates 21 sides of the magnetic device 20. The top of the moving plate 111 is stepped. The side-pressing assembly is connected to the top of the moving plate 111. The side-pressing assembly is located on the side of the magnetic device 20. When the covering device 10 is working, the moving assembly is driven to move so that the side-pressing assembly can apply side pressure to the outer side of the metal terminal 22 so that the metal terminal 22 covers the wire 24.

[0033] In this application, the first side-push assembly 110 and the second side-push assembly 120 are composed of a moving assembly and a side-pressing assembly connected to the moving assembly. This allows the moving assembly to move precisely toward the side of the snap-fit ​​structure 23, changing the shape of the snap-fit ​​structure 23 from a U-shaped to a D-shaped structure. This ensures that the metal terminal 22 and the wire 24 are tightly fitted together, preventing poor electrical connection between the metal terminal 22 and the wire 24 in subsequent soldering processes. This improves the reliability and efficiency of the metal terminal 22 covering the wire 24, while reducing costs.

[0034] In one embodiment, the side-pressing assembly includes a base 113 and a pusher head 114. The base 113 is connected to a moving assembly, and the pusher head 114 is connected to the base 113 and protrudes towards the side of the base 113 near the magnetic device 20. The moving assembly is driven to move, thereby moving the base 113. The movement of the base 113 causes the pusher head 114 to move, so that the metal terminal 22 covers the wire 24. Specifically, the side-pressing assembly includes a base 113 and a pusher head 114. The cross-sectional shape of the base 113 is stepped. The stepped base 113 is connected to the top of the stepped moving plate 111, that is, the base 113 is connected to the moving assembly. The base 113 is provided with at least two spaced slots near the top of the pressing assembly. The two pushers 114 are engaged in the respective slots to connect with the base 113. The two pushers 114 are connected to the base 113 and protrude towards the side of the base 113 near the outer side of the snap-fit ​​structure 23.

[0035] In this application, the side-pressing assembly is composed of a base 113 and a pusher 114, so that the movement of the driving moving assembly can drive the base 113 to move, and the movement of the base 113 drives the pusher 114 to move precisely toward the side close to the outer side of the snap-fit ​​structure 23, so that the shape of the snap-fit ​​structure 23 changes from a U-shaped to a D-shaped structure, further ensuring that the metal terminal 22 and the wire 24 are tightly attached, avoiding poor electrical connection between the metal terminal 22 and the wire 24 in subsequent soldering processes, further improving the reliability and efficiency of the metal terminal 22 covering the wire 24, while reducing costs.

[0036] In one embodiment, the side-pushing mechanism 100 further includes a support component 130, which supports the first side-pushing component 110 and the second side-pushing component 120 and carries the magnetic device 20. Specifically, the support component 130 is connected to the side-pushing plate 400 and supports the first side-pushing component 110 and the second side-pushing component 120. The magnetic device 20 is carried on the support component 130 to ensure that the first side-pushing component 110, the second side-pushing component 120, and the magnetic device 20 are not at risk of shaking during the operation of the covering device 10, thereby further ensuring that the metal terminal 22 and the wire 24 are tightly attached.

[0037] In one embodiment, the support assembly 130 includes a support member 131, a placement seat assembly, and a control assembly. The placement seat assembly is connected to the top of the support member 131, and a pressing assembly is disposed above the placement seat assembly. The placement seat assembly is used to fix the magnetic device 20. The first side push assembly 110 and the second side push assembly 120 are both connected to the support member 131. The control assembly passes through the support member 131 and is connected to the first side push assembly 110 and the second side push assembly 120 on both sides of the support member 131. The control assembly is used to drive the first side push assembly 110 and the second side push assembly 120 to move. Specifically, the support assembly 130 includes a support member 131, a placement seat assembly, a control assembly, and a base plate. The base plate is connected to the upper surface of the side push plate 400. The top of the support member 131 is connected to the upper surface of the base plate. Movable plates 111 of the first side push assembly 110 and the second side push assembly 120 are respectively provided on both sides of the support member 131. The support member 131 has a fixing hole penetrating the support member 131. The control assembly is connected to the support member 131 by engaging in the fixing hole, and the opposite ends of the control assembly are respectively connected to the first side push assembly 110. The moving plate 111 of the first component and the moving plate 111 of the second side push assembly 120 are connected; the placement seat assembly is connected to the top of the support member 131, and the upper part of the placement seat assembly is opposite to the pressing assembly. The placement seat assembly is used to fix the magnetic device 20. The control assembly is used to drive the moving assembly to move the base 113, and the movement of the base 113 drives the push head 114 to move towards the side closer to the outer side of the snap-fit ​​structure 23, so that the shape of the snap-fit ​​structure 23 changes from a U-shaped to a D-shaped structure, so that the metal terminal 22 covers the wire 24. By forming the support assembly 130 with the support member 131, the placement seat assembly and the control assembly, the moving assembly can be driven to move the base 113 by the control assembly, and the movement of the base 113 drives the push head 114 to move towards the side closer to the outer side of the snap-fit ​​structure 23, further ensuring that the metal terminal 22 covers the wire 24.

[0038] In one embodiment, the control assembly includes a side push handle 132, a drive shaft, a first driven shaft 133, and a second driven shaft. The drive shaft is connected to the support member 131 by engaging with a fixing hole. The first driven shaft 133 and the second driven shaft are respectively connected to the drive shaft located on opposite sides of the support member 131. The first driven shaft 133 is connected to the moving plate 111 of the first side push assembly 110, and the second driven shaft is connected to the moving plate 111 of the second side push assembly 120. The side push handle 132 is connected to the first driven shaft 133 and the drive shaft on the side where the first driven shaft 133 is located. The control assembly, consisting of a side push handle 132, a drive shaft, a first driven shaft 133, and a second driven shaft, allows pressing down the side push handle 132 to rotate the drive shaft. The rotation of the drive shaft then rotates the first driven shaft 133 and the second driven shaft connected to it. This rotation of the first driven shaft 133 and the second driven shaft then moves the sliding plate 112 of the first side push assembly 110 and the second push assembly, thereby driving the push head 114 on the base 113 to move towards the side closer to the outer side of the latching structure 23. This design is convenient, labor-saving, and reduces the difficulty of operation.

[0039] In one embodiment, the placement assembly includes a fixing seat 134 and a fixing plate 135. The fixing seat 134 is connected to the top of the support member 131. Side pressing components are provided on both the left and right sides of the fixing seat 134. The fixing plate 135 is connected to both the upper and lower sides of the fixing seat 134. The fixing seat 134 is used to fix the magnetic device 20, and the fixing plate 135 is used to fix the wire 24. Specifically, the placement assembly includes a fixed base 134 and a fixed plate 135. The fixed base 134 is connected to the top of the support member 131. The left and right sides of the fixed base 134 are each provided with a pusher head 114 of a first side-push assembly 110 and a pusher head 114 of a second side-push assembly 120. The upper and lower sides of the fixed base 134 are each connected to the fixed plate 135. The moving plates 111 of the first side-push assembly 110 and the second side-push assembly 120 are correspondingly arranged with the upper and lower sides of the fixed base 134. The fixed base 134 is used to fix the magnetic device 20, and the fixed plate 135 is used to fix the coil wire 24. By using the fixed base 134 and the fixed plate 135 to form the placement assembly, and using the fixed base 134 to fix the magnetic device 20 and the fixed plate 135 to fix the coil wire 24, the risk of movement of the magnetic device 20 and the wire 24 is reduced, thereby further ensuring a tight fit between the metal terminal 22 and the wire 24.

[0040] In one embodiment, a fixing groove 136 is provided on the fixing plate 135 with the slot facing the pressing component. The fixing groove 136 is used to fix the wire 24 of the coil during the operation of the covering device 10, so as to avoid the risk of the wire 24 moving during the operation of the covering device 10, thereby further ensuring that the metal terminal 22 and the wire 24 are tightly attached.

[0041] In one embodiment, the support assembly 130 further includes a slide rail assembly connected to the outside of the support member 131. The first side-push assembly 110 and the second side-push assembly 120 are both slidably connected to the slide rail assembly. The slide rail assembly controls the movement direction of the first side-push assembly 110 and the second side-push assembly 120. Specifically, the slide rail assembly is fixedly connected to the support member 131 and slidably connected to the sliding plate 112. The slide rail assembly controls the push head 114 of the first side-push assembly 110 and the push head 114 of the second side-push assembly 120 to move towards the side closer to the outer surface of the snap-fit ​​structure 23, so that the shape of the snap-fit ​​structure 23 changes from a U-shaped to a D-shaped structure, even when the metal terminal 22 covers the wire 24. The slide rail assembly can precisely control the push head 114 of the first side push assembly 110 and the push head 114 of the second side push assembly 120 to move toward the side closer to the outer side of the snap-fit ​​structure 23, so that the shape of the snap-fit ​​structure 23 changes from a U-shaped shape to a D-shaped shape, thereby further ensuring that the metal terminal 22 and the wire 24 fit tightly together.

[0042] In one embodiment, the slide rail assembly includes two slide rail plates 137 and two limiting blocks 138. The two slide rail plates 137 are respectively connected to the two sides of the moving plate 111 of the support member 131, which is provided with the first side push component 110 and the moving plate 111 of the second side push component 120. The two ends of the two slide rail plates 137 are respectively connected to the two limiting blocks 138. The two limiting blocks 138 are arranged opposite to the two outer sides of the buckle structure 23. The slide rail plate 137 is provided with a sliding groove 261 on the side close to the carrier plate 300 and the side away from the carrier plate 300. The sliding plate 112 is provided with a slider that matches the sliding groove 261. The slide rail assembly can facilitate the movement of the first side push component 110 and the second side push component 120, which is convenient, labor-saving, and reduces the difficulty of operation.

[0043] In one embodiment, the pressing mechanism 200 further includes a fixing component disposed on the side of the side push mechanism 100. The pressing component is slidably connected to the fixing component so that the pressing component can move up and down along the fixing component. Specifically, the fixing component is connected to the side of the side push plate 400, and the pressing component is slidably connected to the fixing component so that the pressing component can move up and down along the fixing component, thereby changing the shape of the snap-fit ​​structure 23 from a D-shaped to an O-shaped structure, so that the metal terminal 22 and the wire 24 are tightly fitted together.

[0044] In one embodiment, the pressing mechanism 200 further includes a limiting component connected to the side of the fixing component near the side-pushing mechanism 100. The limiting component is used to control the movement distance of the pressing component. Specifically, the limiting component includes a limiting plate 210 and a limiting screw 220. The limiting plate 210 is connected to the side of the fixing component near the side-pushing mechanism 100, and the limiting screw 220 passes through the limiting plate 210 along the movement direction of the pressing component. By providing the limiting screw 220 and the limiting plate 210 on the fixing component below the pressing component, the movement distance of the pressing component can be controlled by adjusting the height of the limiting screw 220, thereby further ensuring that the metal terminal 22 and the wire 24 are tightly fitted.

[0045] In one embodiment, the pressing component includes a pressing head seat 230 and a pressing head 240. The pressing head seat 230 is connected to the side of the fixing component near the side push mechanism 100. The pressing head 240 is connected to the lower side of the pressing head seat 230 and the side away from the fixing component. The pressing head seat 230 is located above the limiting component. The pressing head seat 230 is driven to move up and down along the fixing component to drive the pressing head to move up and down.

[0046] In one embodiment, the pressing mechanism 200 further includes a pressing handle 250, and the fixing assembly includes a fixing bracket 260 and a spring 270. The pressing handle 250 is connected to the top of the fixing bracket 260. A groove 261 extending from the top of the fixing bracket 260 toward the top of the fixing bracket 260 is formed on the fixing bracket 260. The side of the fixing bracket 260 near the carrier plate 300 is connected to the limiting plate 210. The pressing head seat 230 is slidably connected to the side of the limiting plate 210 away from the carrier plate 300 with the groove 261. 30 is located on the front side near the fixed bracket 260 and near the magnetic device 20. The pressure head seat 230 is connected to the pressing handle 250 on the top of the fixed bracket 260. The pressing handle 250 is used to drive the pressure head seat 230 to move the pressure head downward toward the magnetic device 20. Springs 270 are provided on both sides of the fixed bracket 260. One end of the spring 270 is connected to the fixed bracket 260, and the other end of the spring 270 is connected to the pressure head seat 230. The spring 270 is used to make it easy for the pressure head seat 230 to return to its original position after being pressed down, while reducing energy consumption.

[0047] The operation process of the coating device 10 is as follows: The magnetic device 20, to which the metal terminals 22 need to be pressed, is placed on the fixed base 134, and the coil wire 24 is fixed in the fixing groove 136 of the fixed plate 135; then, the side push handle 132 is pressed down to drive the drive shaft to rotate. The rotation of the drive shaft will drive the first driven shaft 133 and the second driven shaft connected to the drive shaft to rotate. The rotation of the first driven shaft 133 and the second driven shaft will drive the sliding plate 112 of the first side push assembly 110 and the second push assembly to move. The movement of the sliding plate 112 drives the base 1... The pusher 114 on 13 moves toward the side closer to the outer side of the snap-fit ​​structure 23, causing the shape of the snap-fit ​​structure 23 to change from a U-shaped to a D-shaped structure; then, the push handle 250 is driven downward to move the pressure head seat 230 downward along the slide groove 261, and the movement of the pressure head seat 230 will drive the pressure head to move downward toward the magnetic device 20, so that the shape of the snap-fit ​​structure 23 changes from a D-shaped to an O-shaped structure, so that the metal terminal 22 and the wire 24 are tightly attached, completing the pressing of the metal terminal 22 of the magnetic device 20.
