Description

Technical Field

[0001] The invention relates to the technical field of magnetic core production lines, and in particular to an automatic magnetic core encapsulation system and an encapsulation method. Background Art

[0002] The magnetic core can be used inside small transformers and mutual inductors. Before use, a layer of insulating paper must be wrapped around the outer wall of the magnetic core. This is a necessary process in the production process of small transformers and mutual inductors. This step is referred to as core gluing. The gluing step is to first use tape to stick the first end of the insulating paper to the surface of the magnetic core, then rotate the magnetic core so that the insulating paper wraps the side of the magnetic core, and then use tape to stick the end of the insulating paper. This can prevent scratches or damage to the outer wall of the magnetic core.

[0003] However, due to the complexity of the action of wrapping the magnetic core with insulation paper, the work of wrapping the magnetic core with insulation paper is currently done manually. Workers wrap the insulation paper on the outside of the magnetic core. However, the manual wrapping method is slow, and in the process of packaging the magnetic core, the workers can easily scratch the outer surface of the magnetic core, affecting the quality of the magnetic core.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] Combine the following Figures 1 to 8 , describing an automatic magnetic core encapsulation system and encapsulation method according to an embodiment of the present invention.

[0054] An automatic magnetic core encapsulation system, the encapsulation device 4 comprises a moving mechanism 41, an insulating paper winding mechanism 42, an adhesive tape pasting mechanism 43, a magnetic core clamping mechanism 44 and a magnetic core pressing mechanism 45;

[0055] The magnetic core clamping mechanism 44 includes a rotating assembly 441, a first clamping member 442 and a second clamping member 443. The first clamping member 442 and the second clamping member 443 are close to each other and clamp the magnetic core. The rotating assembly 441 is used to drive the first clamping member 442 and the second clamping member 443 to rotate synchronously.

[0056] The moving mechanism 41 is located at the right end of the magnetic core clamping mechanism 44. The moving mechanism 41 includes a moving guide rail 411 and a moving manipulator assembly 412. One end of the moving guide rail 411 is located above the positioning carrier, and the other end is located above the first clamping member 442 and the second clamping member 443. The moving manipulator 4124 is slidably connected to the moving guide rail 411. The moving manipulator 4124 is used to move the assembled magnetic core to be encapsulated to the magnetic core clamping mechanism 44.

[0057] The insulating paper winding mechanism 42 is located at the front end of the magnetic core clamping mechanism 44, and the insulating paper winding mechanism 42 includes an insulating paper unwinding roller 421, a clamping assembly 422 and a paper cutter 423. The insulating paper unwinding roller 421 is used to place an insulating paper roll, and the end of the insulating paper roll away from the winding roller is wound around the magnetic core. The clamping assembly 422 is used to clamp the end of the insulating paper away from the insulating paper unwinding roller 421. The paper cutter 423 is located at one end of the clamping assembly 422 close to the magnetic core clamping mechanism 44, and the paper cutter 423 is used to cut the insulating paper;

[0058] The tape sticking mechanism 43 is located at the rear end of the magnetic core clamping mechanism 44, and the tape sticking mechanism 43 is used to stick the segmented tape to the insulating paper;

[0059] The magnetic core pressing mechanism 45 is located at the rear end of the magnetic core clamping mechanism 44 . The magnetic core pressing mechanism 45 comprises a pressing roller 451 . The pressing roller 451 is used to press the insulating paper on the assembled magnetic core.

[0060] When the moving mechanism 41 identifies and locates the carrier, the moving manipulator 4124 first moves on the moving guide rail 411 to move the assembled magnetic core to be encapsulated onto the magnetic core clamping mechanism 44. The first clamping member 442 and the second clamping member 443 on the magnetic core clamping mechanism 44 can clamp the assembled magnetic core and then drive the assembled magnetic core to rotate in place.

[0061] At this time, the insulating paper unwinding roller 421 on the insulating paper winding mechanism 42 starts to unwind the insulating paper, so that the end of the insulating paper passes through the clamping assembly 422 and is then located on the assembled magnetic core. The tape sticking mechanism 43 can stick the segmented tape to the insulating paper to ensure that the end of the insulating paper away from the insulating paper unwinding roller 421 is in close contact with the magnetic core.

[0062] Since the magnetic core clamping mechanism 44 drives the assembled magnetic core to rotate all the time, the insulating paper can be wound around the assembled magnetic core. When the insulating paper is wound, the magnetic core clamping mechanism 44 stops rotating, the clamping assembly 422 starts clamping the insulating paper, so that the insulating paper stops moving, and then the paper cutter 423 cuts the insulating paper, so that the insulating paper on the assembled magnetic core is segmented insulating paper.

[0063] At this time, the tape sticking mechanism 43 continues to stick the segmented tape to the end of the segmented insulating paper to ensure that the insulating paper is close to the magnetic core and reduce the separation of the magnetic core and the insulating paper. In the process of winding the insulating paper, the pressing roller 451 in the magnetic core pressing mechanism 45 can press the insulating paper at all times to further ensure that the insulating paper is close to the magnetic core and reduce the bulging of the insulating paper on the surface of the magnetic core.

[0064] Therefore, the above-mentioned multiple mechanisms cooperate with each other to automatically wind the insulating paper on the assembled magnetic core to complete the encapsulation process, thereby solving the problem that the traditional magnetic core encapsulation requires manual work, has low encapsulation efficiency, and low production capacity.

[0065] The mobile manipulator assembly 412 includes a first mobile slider 4121, a mobile lifting member 4122, a second mobile slider 4123 and a mobile manipulator 4124, the first mobile slider 4121 is slidably connected to the mobile guide rail 411, a mobile lifting member 4122 is provided on the top of the first mobile slider 4121, a lifting end of the mobile lifting member 4122 is fixedly connected to the second mobile slider 4123, the second mobile slider 4123 is slidably connected to the first mobile slider 4121, the mobile lifting member 4122 is used to drive the second mobile slider 4123 to rise and fall in the vertical direction, a mobile manipulator 4124 is provided at the bottom of the second mobile slider 4123, and the mobile manipulator 4124 is used to clamp and assemble the magnetic core;

[0066] A moving cylinder is provided on the moving guide rail 411 , and a driving end of the moving cylinder is connected to the first moving slider 4121 . The moving cylinder is used to start the first moving slider 4121 to slide on the moving guide rail 411 .

[0067] Reference Figure 1 and Figure 2 , start the moving cylinder, which can adjust the position of the first moving slider 4121 so that the first moving slider 4121 is located above the assembled magnetic core. Then start the moving lifting member 4122, which can drive the mobile manipulator 4124 to move in the vertical direction and clamp the assembled magnetic core.

[0068] Continue to start the moving cylinder, which transports the first moving slider 4121 and the moving manipulator 4124 to the magnetic core clamping mechanism 44, thereby completing the transportation work before encapsulation.

[0069] An automatic magnetic core encapsulation system wherein two mobile manipulator assemblies 412 are provided, and the two mobile manipulator assemblies 412 are respectively slidably connected to the mobile guide rail 411, and the mobile manipulator assemblies 412 are used to clamp and transport the assembled magnetic core;

[0070] The moving mechanism 41 further includes two L-shaped pieces 413 arranged in parallel, one of the L-shaped pieces 413 is used to place the assembled magnetic core to be coated with rubber, and the other L-shaped piece 413 is used to place the assembled magnetic core that has been coated with rubber.

[0071] It is worth noting that in this solution, two mobile manipulator assemblies 412 and two L-shaped parts 413 are provided. Specifically, the mobile manipulator assembly 412 located on the left is the first mobile manipulator assembly, and the mobile manipulator assembly 412 located on the right is the second mobile manipulator assembly; the L-shaped part 413 located on the left is the first L-shaped part, and the L-shaped part 413 located on the right is the second L-shaped part.

[0072] The operation process of the moving mechanism 41 is as follows: the first moving manipulator assembly moves the assembled magnetic core to be encapsulated into the second L-shaped piece, and the second moving manipulator assembly moves the assembled magnetic core to be encapsulated from the second L-shaped piece to the magnetic core clamping mechanism 44. After the encapsulation is completed, the second moving manipulator assembly moves the encapsulated assembled magnetic core from the magnetic core clamping mechanism 44 to the first L-shaped piece, and the first moving manipulator assembly moves the encapsulated assembled magnetic core in the first L-shaped piece to the positioning carrier.

[0073] In this solution, two mobile manipulator assemblies 412 and two L-shaped members 413 are provided, so that the two manipulators can operate synchronously, shortening the handling time of the assembled magnetic core and improving the handling effect.

[0074] The rotating assembly 441 includes a rotating motor 4411, a rotating shaft 4412, a first rotating belt 4413 and a second rotating belt 4414. The driving end of the rotating motor 4411 is fixedly connected to the rotating shaft 4412. The rotating shaft 4412 is located below the first clamping member 442 and the second clamping member 443. The length direction of the rotating shaft 4412 is the connecting direction of the first clamping member 442 and the second clamping member 443. The first rotating belt 4413 is sleeved on the first clamping member 442 and one end of the rotating shaft 4412. The second rotating belt 4414 is sleeved on the second clamping member 443 and the other end of the rotating shaft 4412.

[0075] Reference Figure 5 When the head end of the insulating paper is located on the assembled magnetic core, the rotating motor 4411 is started, and the rotating motor 4411 can drive the rotating shaft 4412 to rotate. Since the first rotating belt 4413 and the second rotating belt 4414 are respectively provided at both ends of the rotating shaft 4412, the first rotating belt 4413 can drive the first clamping member 442 to rotate, and the second rotating belt 4414 can drive the second clamping member 443 to rotate, so that the first clamping member 442 and the second clamping member 443 rotate in the same direction and at the same speed, thereby driving the assembled magnetic core to rotate together.

[0076] The clamping assembly 422 includes a first clamping roller 4221, a second clamping roller 4222, a clamping mounting plate 4223, a clamping lifting member 4224 and a buffer member 4225. The first clamping roller 4221 and the second clamping roller 4222 are arranged opposite to each other. The gap between the first clamping roller 4221 and the second clamping roller 4222 is used for the insulating paper to pass through. The second clamping roller 4222 is rotatably connected to the clamping mounting plate 4223. The clamping mounting plate 4223 is installed on the Above the second clamping roller 4222, a buffer 4225 and a clamping lifting member 4224 are installed on the top of the clamping mounting plate 4223.

The first clamping roller 4221 and the second clamping roller 4222 are used to clamp insulating paper.

[0077] Reference Figure 3 and Figure 4 , the insulating paper unwinding roller 421 starts to unwind the insulating paper, and the end of the insulating paper passes through the clamping assembly 422, so that the clamping assembly 422 can clamp the insulating paper.

[0078] The first clamping roller 4221 and the second clamping roller 4222 are arranged opposite to each other, and the insulating paper passes through the gap between the first clamping roller 4221 and the second clamping roller 4222. Then the clamping lifting member 4224 is started, driving the clamping mounting plate 4223 to move downward in the vertical direction, and the clamping mounting plate 4223 can drive the buffer member 4225 and the second clamping roller 4222, so that the second clamping roller 4222 presses the insulating paper downward, so that the first clamping roller 4221 and the second clamping roller 4222 can clamp the insulating paper in the vertical direction to limit the movement of the insulating paper.

[0079] In order to reduce the wear between the first clamping roller 4221 and the second clamping roller 4222, a buffer 4225 is provided between the clamping mounting plate 4223 and the first clamping roller 4221.

[0082] It is worth noting that the tensioning roller set 424 can adjust the tension of the insulating paper so that the insulating paper is always kept within a suitable tension range to prevent the insulating paper from being too tight or too loose.

[0083] In addition, the guide limit grooves in the guide limit frame 425 can guide the movement direction of the insulating paper to prevent the insulating paper from being offset and making it difficult to wind and assemble the magnetic core.

[0084] The magnetic core pressing mechanism 45 further includes a first pressing guide rail 452, a first pressing slider 453, a second pressing guide rail 454, a second pressing slider 455 and a tape limiting fixture 456;

[0087] Reference Figure 8 When the head end of the segmented insulating paper is located outside the assembled magnetic core, the first pressing cylinder is started, and the first pressing cylinder can drive the first pressing slider 453 to move on the first pressing guide rail 452. Since the first pressing slider 453 is connected to the pressing roller 451 through the pressing connecting rod, the first pressing slider 453 can drive the pressing roller 451 to move together, so that the pressing roller 451 can contact the insulating paper on the assembled magnetic core, ensuring that the insulating paper is tightly attached to the assembled magnetic core.

[0088] Then, when the end of the segmented insulating paper is wound around the assembled magnetic core, the assembled magnetic core stops rotating. The second pressing cylinder is started, and the second pressing cylinder can drive the second pressing slider 455 to move on the second pressing guide rail 454. Since the second pressing slider 455 is connected to the tape limiting clamp 456 through the pressing connecting rod, the second pressing slider 455 can drive the tape limiting clamp 456 to move together, ensuring that the tape limiting clamp 456 can clamp the assembled magnetic core wrapped with the insulating paper.

[0089] Specifically, the tape limiting clamp 456 can clamp the two ends of the assembled magnetic core and limit the sticking position of the tape so that the tape is stuck to the left and right ends of the segmented insulating paper to avoid the segmented insulating paper from warping.

[0090] The tape pasting mechanism 43 includes a tape unwinding roller 431, a tape limiting frame 432, a pair of scissors 433, a tape clamping assembly 434 and a tape moving assembly 435 in sequence along the unwinding direction of the tape. The tape unwinding roller 431 is used to unwind the tape roll, the tape clamping assembly 434 is used to clamp the end of the tape roll, the end of the tape roll passes through the tape limiting frame 432 and is located in the tape clamping assembly 434, the scissors 433 are used to cut the tape, and the tape moving assembly 435 includes a transfer block 4355, the transfer block 4355 is located between the tape limiting frame 432 and the tape clamping assembly 434, and the transfer block 4355 is used to stick the tape and transfer the tape to the core clamping mechanism.

[0091] The tape roll on the tape unwinding roller 431 begins to unwind, and the end of the tape away from the tape roll passes through the tape limiting frame 432 and is located in the tape clamping assembly 434. The tape clamping assembly 434 can clamp the tape so that the tape appears in a straight state, thereby facilitating the scissors 433 to cut the tape. Among them, the tape limiting frame 432 can limit the movable position of the tape to prevent the tape clamping assembly 434 from being unable to clamp the tape.

[0092] After cutting the tape, the end of the transfer piece on the tape moving assembly 435 is provided with a segmented tape that is transferred to the assembled magnetic core, so that the segmented tape can adhere to the beginning and end of the segmented insulating paper, ensuring that the insulating paper can be wrapped around the assembled magnetic core to complete the encapsulation work.

[0093] The tape moving assembly 435 includes a first tape moving guide rail 4351, a first tape moving slider 4352, a second tape moving guide rail 4353 and a second tape moving slider 4354;

[0094] The first tape moving guide rail 4351 is located at the rear end of the magnetic core clamping mechanism, and the length direction of the first tape moving guide rail 4351 is the left-right direction. The first tape moving guide rail 4351 is equipped with a first tape moving cylinder, and the driving end of the first tape moving cylinder is connected to the first tape moving slider 4352, and the first tape moving slider 4352 is slidably connected to the first tape moving guide rail 4351, and the second tape moving slider 4354 is provided with a vertical second tape moving guide rail 4353. The first tape moving guide rail 4351 is equipped with a second tape moving cylinder, and the driving end of the second tape moving cylinder is connected to the second tape moving slider 4354, and the second tape moving slider 4354 is slidably connected to the second tape moving guide rail 4353, and the transfer block 4355 is fixedly installed at the bottom of the second tape moving slider 4354.

[0095] Among them, start the first tape moving cylinder, the first tape moving cylinder can drive the first tape moving slider 4352 to move left and right on the first tape moving guide rail 4351, so that the transfer block 4355 is located directly above the segmented tape. Then start the second tape moving cylinder, the second tape moving cylinder can move the second tape moving slider 4354 and the transfer block 4355 downward, so that the transfer block 4355 can contact the segmented tape. Continue to start the first tape moving cylinder, so that the first tape moving cylinder can indirectly drive the transfer block 4355 to move to the assembled magnetic core, ensure that the segmented tape can adhere to the beginning and end of the segmented insulating paper, so that the insulating paper can tightly wrap the assembled magnetic core, and complete the encapsulation process of the assembled magnetic core.

[0096] The tape limiting frame 432 is horizontally provided with a tape through hole, and the left and right ends of the tape through hole penetrate the tape limiting frame 432. The top of the tape limiting frame 432 is provided with a tape pressing groove, and the tape pressing groove is connected to the tape through hole.

[0097] The tape sticking mechanism 43 also includes a tape pressing component 436, which includes a tape pressing lifting member 4361, a tape pressing mounting plate 4362 and a tape pressing block 4363. The tape pressing mounting plate 4362 is located at the top of the tape limiting frame 432, and the tape pressing block 4363 is fixedly installed at the bottom of the tape pressing mounting plate 4362. The bottom of the tape pressing block 4363 is movably penetrated by the tape through hole, and the top of the tape pressing mounting plate 4362 is installed with a tape pressing lifting member 4361, and the tape pressing lifting member 4361 is used to lift the tape pressing mounting plate 4362 and the tape pressing block 4363 in the vertical direction.

[0098] The cross-sectional area of ​​the bottom of the tape pressing block 4363 is trapezoidal;

[0099] The tape limiting frame 432 is fixedly provided with a tape protrusion block 4364 in the tape through hole, and the cross-sectional shape of the tape protrusion block 4364 is a trapezoid.

[0100] Reference Figure 7 A tape through slot is provided in the tape limiting frame 432, and the tape through slot can limit the range of movement of the tape to prevent the tape from being displaced and causing the failure of the encapsulation.

[0101] Before the scissors 433 need to cut the tape, the tape pressing lifting member 4361 on the tape pressing assembly 436 is activated, and the tape pressing lifting member 4361 drives the tape pressing mounting plate 4362 and the tape pressing block 4363 to move in the vertical direction, so that the tape pressing block 4363 moves downward and extends into the tape pressing groove to press the tape. At this time, the tape pressing block 4363 and the tape protrusion block 4364 cooperate with each other to clamp the tape, so that the tape appears in a straight state before cutting, thereby facilitating the scissors 433 to cut the tape quickly and accurately.

[0102] Among them, this solution also limits the shape of the tape pressure block 4363 and the tape protrusion block 4364, reducing the contact area between the tape and the tape protrusion block 4364 and the tape pressure block 4363 respectively, to avoid the tape sticking to the tape protrusion block 4364 or the tape pressure block 4363 and becoming difficult to transfer.

[0103] A method for encapsulating a magnetic core using an automatic encapsulating system, comprising the following steps:

[0104] Step 1, the moving mechanism 41 moves the assembled magnetic core to be encapsulated to the magnetic core clamping mechanism 44;

[0105] Step 2, the magnetic core clamping mechanism 44 clamps and rotates the assembled magnetic core;

[0106] Step 3, the insulating paper winding mechanism 42 winds the insulating paper on the assembled magnetic core, and the pressing roller 451 presses the insulating paper;

[0107] Step 4, the tape sticking mechanism 43 cuts the tape and transfers the tape to the assembled magnetic core, and the tape limiting fixture 456 limits the sticking position of the tape;

[0108] Step 5: The moving mechanism 41 moves the assembled magnetic core after the encapsulation from the magnetic core clamping mechanism 44 to the positioning carrier.

[0109] First, the glue spraying device 2 sprays glue on the magnetic core, so that each magnetic core has a layer of glue on its upper surface, thereby facilitating the subsequent assembly of the magnetic core. The stacking device 3 can assemble the single magnetic cores to form an assembled magnetic core. The assembled magnetic core is then transported to the moving mechanism 41, and is transported to the magnetic core clamping mechanism 44 by the moving mechanism 41. During the clamping process of the magnetic core clamping mechanism 44, insulating paper is wrapped on the surface of the assembled magnetic core, and the insulating paper is adhered to the assembled magnetic core with tape, thereby completing the insulating paper encapsulation process.

[0110] At this time, the solution has a high degree of automation, and the magnetic core encapsulation method of the solution is simple, and the magnetic core can be automatically assembled and encapsulated, which improves the assembly efficiency of the magnetic core and further solves the problems of low assembly efficiency and low production capacity of traditional magnetic cores.
