[0002] Transformers are generally assembled from multiple parts such as a skeleton, an assembled magnetic core, and a coil. Among them, the staff needs to stick multiple small magnetic cores to each other and stack them up to form an assembled magnetic core. The outer wall of the assembled magnetic core also needs to be wrapped with a layer of insulating paper, which can scratch or damage the outer wall of the assembled magnetic core. At present, the assembly process of the transformer requires a large number of people to operate, which not only reduces production efficiency, but also the product is prone to defective products due to many human factors, such as the magnetic core being skewed during stacking, and there being a large gap between the insulating paper and the assembled magnetic core. Moreover, manual operation requires high labor costs, and as the workers become fatigued over time, the processing efficiency is low. Summary of the invention

[0013] Combine the following Figures 1 to 28 , describing a transformer automated production line and an assembly method thereof according to an embodiment of the present invention.

[0014] A transformer automated production line, comprising a frame 1, a conveying device and a positioning carrier, wherein the conveying device is used to convey the positioning carrier 01 on the frame, and the frame 1 comprises a magnetic core feeding and transfer device 7, a skeleton feeding device 5, a glue spraying device 2, a stacking device 3, an air gap sheet feeding device 6, a glue coating device 4, a coil feeding device 81, a coil assembling device 82 and a flipping device 83 in sequence along the conveying direction of the conveying device;

[0015] The magnetic core loading and transfer device 7 is used to load the magnetic core onto the positioning carrier 01; the skeleton loading device 5 is used to load the skeleton onto the positioning carrier 01; the glue spraying device 2 is used to spray glue on the skeleton and the magnetic core; the stacking device 3 is used to stack multiple magnetic cores into an assembled magnetic core; the air gap sheet loading device 6 is used to load the air gap sheet onto the positioning carrier 01; the glue coating device 4 is used to glue the assembled magnetic core; the coil loading device 81 is used to load the coil onto the positioning carrier 01; the coil assembling device 82 is used to place the assembled magnetic core that has been glued in the coil; the flipping device 83 is used to place the skeleton on the coil.

[0016] In the present scheme, a transformer automated production line is provided, wherein the conveying device is a circular unidirectional conveyor belt, on which a plurality of positioning carriers 01 are evenly arranged, and the conveying device can convey the plurality of positioning carriers 01 to various corners of the rack 1 .

[0017] The frame 1 includes a core feeding and transfer device 7, a frame feeding device 5, a glue spraying device 2, a stacking device 3, an air gap feeding device 6, a glue coating device 4, a coil feeding device 81, a coil assembly device 82, and a flipping device 83 in sequence along the conveying direction of the conveying device. Through the mutual cooperation of multiple above-mentioned devices, the present solution can automatically assemble the transformer, with a high degree of automation and can operate uninterruptedly, solving the problem that the traditional transformer needs to be manually assembled and has low assembly efficiency.

[0018] The skeleton feeding device 5 and the air gap sheet feeding device 6 have the same structure, and both the skeleton feeding device 5 and the air gap sheet feeding device 6 include a feeding manipulator 51, a vibration plate 52, a feeding monitor 53, a feeding display screen 56, a feeding conveyor belt 54 and a feeding guide plate 55; the feeding monitor 53 is located on the top of the vibration plate 52, and the monitoring range of the feeding monitor 53 is toward the vibration plate 52, and the positioning carrier plate 01 is located within the activity range of the feeding manipulator 51;

[0019] The output end of the loading conveyor belt 54 is located above the vibration disk 52, and the bottom of the output end of the loading conveyor belt 54 is provided with an inclined loading guide plate 55, and the end of the loading guide plate 55 away from the loading conveyor belt 54 is located above the vibration disk 52; vertical baffles 551 are provided on both sides of the loading guide plate 55; the vibration disk 52 is provided with a vibration enclosure 521, and the vibration enclosure 521 is inclined outward; the loading display screen 56 is electrically connected to the loading monitor 53.

[0020] A plurality of frames (or air gap pieces) are placed on the vibration disk 52, and then the vibration disk 52 starts to vibrate, causing the plurality of frames (or air gap pieces) to shake inside the vibration disk 52. Some frames can be flipped to a front-facing state under the action of the vibration disk 52; some air gap pieces can be dispersed under the action of the vibration disk 52.

[0021] At this time, the loading monitor 53 in the skeleton loading device 5 can always monitor the position and status of multiple skeletons in the current vibration disk 52, and transmit the position information of the skeleton facing up in the vibration disk 52 to the loading robot 51 in the skeleton loading device 5. After receiving the information, the loading robot 51 clamps the skeleton facing up and rotates it into the skeleton mounting groove 0122. Then the positioning pin assembly 0121 can fix the skeleton in the skeleton mounting groove 0122 to prevent the skeleton from moving on the positioning carrier 01.

[0022] At this time, the loading monitor 53 in the air gap piece loading device 6 can always monitor the positions of multiple air gap pieces in the current vibration disk 52, and transmit the position information of the air gap pieces in the vibration disk 52 to the loading robot 51 in the air gap piece loading device 6. After receiving the information, the loading robot 51 clamps the air gap piece and rotates it to a specific position of the positioning carrier 01.

[0023] Among them, the bottom of the feeding manipulator 51 in the air gap sheet feeding device 6 is provided with an air gap sheet feeding suction cup 61. Since the air gap sheet is small in size and thin in thickness, if the feeding manipulator 51 is directly used to clamp the air gap sheet, the clamping failure may occur. Therefore, an air gap sheet feeding suction cup 61 is provided at the bottom of the feeding manipulator 51. The air gap sheet feeding suction cup 61 has the advantages of large contact area, no damage to the surface of the air gap sheet, and strong adsorption, and can quickly adsorb the air gap sheet and transfer the air gap sheet to a specific position of the positioning carrier 01.

[0024] It is worth mentioning that an air gap monitor 62 is also provided on the rack 1, and the air gap monitor 62 is electrically connected to the air gap alarm. The monitoring range of the air gap monitor 62 is toward the positioning carrier 01, so that the air gap monitor 62 can monitor the position of the air gap on the positioning carrier 01.

[0025] When the air gap monitor 62 detects that the position of the air gap on the positioning carrier 01 is wrong, the signal is transmitted to the air gap alarm, and the air gap alarm sounds an alarm to remind the staff to adjust the position of the air gap in time and check whether the loading robot 51 is faulty.

[0026] The glue spraying device 2 comprises a spray gun 21, a first glue spraying guide rail 22, a second glue spraying guide rail 23, a first glue spraying slider 24 and a second glue spraying slider 25, wherein the first glue spraying guide rail 22 is located directly above the frame 1, the length direction of the first glue spraying guide rail 22 is the left-right direction, the first glue spraying guide rail 22 is slidably connected to the first glue spraying slider 24, the first glue spraying slider 24 is provided with a vertical second glue spraying guide rail 23, the second glue spraying guide rail 23 is slidably connected to the second glue spraying slider 25, the second glue spraying slider 25 is fixedly mounted with the spray gun 21, and the nozzle of the spray gun 21 faces the magnetic core;

[0027] The first glue spraying guide rail 22 is equipped with a first glue spraying cylinder 26 , and the driving end of the first glue spraying cylinder 26 is fixedly connected to the first glue spraying slider 24 . The second glue spraying guide rail 23 is equipped with a second glue spraying cylinder 27 , and the driving end of the second glue spraying cylinder 27 is fixedly connected to the second glue spraying slider 25 .

[0028] The first glue spraying cylinder 26 is activated according to the position of the magnetic core, which can drive the first glue spraying slider 24 to move left and right on the first glue spraying guide rail 22, so that the spray gun 21 is located directly above the magnetic core. Then the second glue spraying cylinder 27 is activated, so that the second glue spraying slider 25 moves up and down on the second glue spraying guide rail 23. The second glue spraying cylinder 27 can drive the second glue spraying slider 25 and the spray gun 21 to move, so that the spray gun 21 can spray glue on multiple magnetic cores arranged side by side, and then the glue spraying action is completed.

[0029] It is worth noting that a glue spraying device 2 is also provided between the stacking device 3 and the air gap sheet feeding device 6 , and the first glue spraying guide rail 22 of the glue spraying device 2 is in the front-to-back direction, so that the glue spraying device 2 can spray glue on the frame.

[0030] The rubber coating device 4 includes a moving mechanism 41, an insulating paper winding mechanism 42, an adhesive tape sticking mechanism 43, a magnetic core clamping mechanism 44 and a magnetic core pressing mechanism 45;

[0031] 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.

[0032] 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 4124 assembly 412. One end of the moving guide rail 411 is located above the positioning carrier 01, 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.

[0033] 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 away from the insulating paper unwinding roller 421 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;

[0034] 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;

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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. The 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. The mobile manipulator 4124 is used to clamp and assemble the magnetic core. A mobile cylinder is provided on the mobile guide rail 411. The driving end of the mobile cylinder is connected to the first mobile slider 4121. The mobile cylinder is used to start the first mobile slider 4121 to slide on the mobile guide rail 411.

[0042] 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. Continue to start the moving cylinder, which transports the first moving slider 4121 and the mobile manipulator 4124 to the magnetic core clamping mechanism 44, thereby completing the handling work before encapsulation.

[0043] 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;

[0044] 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 of the L-shaped pieces 413 is used to place the assembled magnetic core that has been coated with rubber.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

Among them, 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. The clamping mounting plate 4223 can drive the buffer 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.

[0052] 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.

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.

[0062] 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.

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.

[0065] 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.

[0066] 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.

[0068] A tape slot is provided in the tape limiting frame 432, and the tape slot can limit the range of movement of the tape to prevent the tape from being offset and causing the failure of the rubber coating. Before the scissors 433 need to cut the tape, the tape pressing lifting member 4361 on the tape pressing assembly 436 is started, 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 slot 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.

[0069] 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.

[0079] The second magnetic core loading moving assembly 724 includes a second magnetic core loading moving guide rail 7241 and a second magnetic core loading moving slider 7242. One end of the second magnetic core loading moving guide rail 7241 is located below the magnetic core transfer mechanism 73, and the other end is located on one side of the positioning carrier. The second magnetic core loading moving guide rail 7241 and the second magnetic core loading moving slider 7242 are slidably connected.

[0080] The first magnetic core loading lifting assembly 721 is located below the magnetic core plate storage space 711, and is used to transport the magnetic core plate at the bottom of the magnetic core plate storage space 711 to the first magnetic core loading moving slider 7232 below; the second magnetic core loading lifting assembly 722 is located below the magnetic core plate recovery space 712, and is used to transport the unloaded magnetic core plates on the first magnetic core loading moving slider 7232 to the magnetic core plate recovery space 712 above one by one;

[0081] The magnetic core transfer mechanism 73 includes a first magnetic core transfer robot assembly 731 and a second magnetic core transfer robot assembly.

[0082] A magnetic core loading and transfer device of the present solution places multiple magnetic cores in a magnetic core plate, which can facilitate the storage and transportation of the magnetic cores. Moreover, the magnetic core plates filled with magnetic cores can be stacked and placed in the magnetic core plate storage space 711. At this time, the first magnetic core loading lifting assembly 721 transports the single magnetic core plate in the magnetic core plate storage space 711 to the first magnetic core loading moving slider 7232 below, the first magnetic core loading moving slider 7232 transports the magnetic core plate to the bottom of the first magnetic core transfer manipulator assembly 731, and the first magnetic core transfer manipulator assembly 731 transfers the magnetic core on the magnetic core plate to the second magnetic core loading moving slider 7242. After all the magnetic cores on a magnetic core plate are transferred to the first magnetic core loading moving slider 7232, the first magnetic core loading moving slider 7232 transports the unloaded magnetic core plate to the bottom of the magnetic core plate recovery space 712, and the second magnetic core loading lifting assembly 722 is started to transport the unloaded magnetic core plate on the first magnetic core loading moving slider 7232 to the upper magnetic core plate recovery space 712.

[0083] At the same time, the second magnetic core loading moving slider 7242 moves on the second magnetic core loading moving guide rail 7241, and then transports the second magnetic core loading moving guide rail 7241 to the vicinity of the positioning carrier. At this time, the second magnetic core transfer robot assembly transfers the magnetic core on the second magnetic core loading moving slider 7242 to the positioning carrier, thereby completing the magnetic core loading process.

[0084] By repeating the above process, the magnetic core loading and transfer device of the present scheme can not only load and transfer multiple magnetic cores in the magnetic core bin 71 to multiple positioning carriers, but also automatically recycle empty magnetic core plates, making it convenient for staff to quickly recycle the magnetic core plates, thereby further improving the loading efficiency of the magnetic cores.

[0085] Moreover, the core material bin 71 can store multiple core plates at one time, reducing the frequency of workers replenishing and replacing the core plates, and further solving the problem that the traditional production line needs to manually transfer the cores to the positioning plate, has a low degree of automation, and has a slow loading efficiency.

[0086] The magnetic core bin 71 includes a first bin limiting column 713, a second bin limiting column 714, a third bin limiting column 715, a fourth bin limiting column 716, a fifth bin limiting column 717, a sixth bin limiting column 718 and a bin mounting plate 719, and the outer edges of the bin mounting plate 719 are horizontally connected to the first bin limiting column 713, the second bin limiting column 714, the third bin limiting column 715, the fourth bin limiting column 716, the fifth bin limiting column 717 and the sixth bin limiting column 718 respectively;

[0087] The silo mounting plate 719, the third silo limiting column 715, the fourth silo limiting column 716, the first silo limiting column 713 and the second silo limiting column 714 form a square magnetic core plate storage space 711, and the silo mounting plate 719, the fifth silo limiting column 717, the sixth silo limiting column 718, the first silo limiting column 713 and the second silo limiting column 714 form a square magnetic core plate recovery space 712;

[0088] The silo mounting plate 719 is provided with a core board pressing assembly 7110 at the core board storage space 711, and the core board pressing assembly 7110 is used to support the core board. The silo mounting plate 719 is provided with a core board limiting assembly 7120 at the core board recovery space 712, and the core board limiting assembly 7120 is used to limit the core board from falling downward.

[0089] Two through holes are provided in the center of the silo mounting plate 719, so that the magnetic core plate can move through the through holes. Then the first silo limiting column 713, the second silo limiting column 714, the third silo limiting column 715, the fourth silo limiting column 716, the fifth silo limiting column 717 and the sixth silo limiting column 718 respectively abut against the four corners of the magnetic core plate, and the position of the magnetic core plate can be limited so that the magnetic core plate can only be located in the corresponding magnetic core plate storage space 711 and the magnetic core plate recovery space 712.

[0090] Since the magnetic core plate can move through the through hole, a magnetic core plate pressing assembly 7110 and a magnetic core plate limiting assembly 7120 are provided on the silo mounting plate 719 to limit the position of the magnetic core plate and prevent the magnetic core plate from suddenly passing through the through hole during operation, thereby causing an error.

[0091] The first magnetic core loading and lifting assembly 721 and the second magnetic core loading and lifting assembly 722 have the same structure. The first magnetic core loading and lifting assembly 721 and the second magnetic core loading and lifting assembly 722 both include a first magnetic core loading and lifting plate 7211 and a first magnetic core loading cylinder 7212. The two ends of the first magnetic core loading and lifting plate 7211 are respectively fixedly connected to the driving ends of the two first magnetic core loading cylinders 7212. The mounting end of the first magnetic core loading cylinder 7212 is vertically mounted on the frame 1. The first magnetic core loading and lifting plate 7211 can be movably abutted against the bottom of the magnetic core plate.

[0092] The two first core loading cylinders 7212 are started simultaneously, and the piston rods are extended upward, so that the two ends of the first core loading lifting plate 7211 rise in the same direction and at the same speed, and then abut against the bottom of the core plate and support the core plate, thereby driving the core plate to rise or fall.

[0093] In conjunction with the core plate pressing assembly 7110 and the core plate limiting assembly 7120, the core plate with the magnetic core can be transported from the core plate storage space 711 to the first core loading moving slider 7232, and the empty core plate can be transported from the first core loading moving slider 7232 to the core plate recovery space 712.

[0094] The core plate pressing assembly 7110 includes a core plate pressing cylinder 7111 and a core plate pressing block 7112. The driving end of the core plate pressing cylinder 7111 is fixedly connected to the core plate pressing block 7112, and the core plate pressing block 7112 abuts against the bottom of the core plate. When the core plate pressing cylinder 7111 is started, the piston rod of the core plate pressing cylinder 7111 drives the core plate pressing block 7112 to move, so that the core plate pressing block 7112 abuts against the bottom of the core plate at the bottom of the core plate storage space 711. At this time, the core plate pressing block 7112 can support multiple core plates.

[0095] When the core moving mechanism 72 needs to transport the core plate to the core transfer mechanism 73, the first core loading lifting assembly 721 supports the bottom core plate in the core plate storage space 711 upwards, and then starts the core plate pressing cylinder 7111, so that the core plate pressing cylinder 7111 drives the core plate pressing block 7112 to shrink inwards and separate from the core plate. Next, the first core loading lifting assembly 721 drives multiple core plates to move downwards, and when the bottom core plate in the core plate storage space 711 is located below the silo mounting plate 719, the core plate pressing cylinder 7111 is started, so that the core plate pressing cylinder 7111 drives the core plate pressing block 7112 to move outwards, thereby supporting the second to last core plate in the core plate storage space 711, ensuring that the first core loading moving slider 7232 can only transport one core plate to the bottom of the core transfer mechanism 73 at a time.

[0096] The core plate limiting assembly 7120 includes a core limiting mounting block 7121, a core limiting block 7122, a first core limiting magnetic component 7123 and a second core limiting magnetic component 7124. The core limiting mounting block 7121 is provided with a core limiting block accommodating groove. The bottom of the core limiting block 7122 is rotatably connected to the inner wall of the core limiting block accommodating groove. The inner wall of the core limiting accommodating groove is inlaid with the first core limiting magnetic component 7123. The top of the core limiting block 7122 is inlaid with the second core limiting magnetic component 7124. The first core limiting magnetic component 7123 and the second core limiting magnetic component 7124 are arranged opposite to each other and repel each other. The core limiting block 7122 is provided with a core limiting inclined surface 7125 on the side close to the core plate.

[0097] Since the first magnetic core limiting magnetic member 7123 and the second magnetic core limiting magnetic member 7124 repel each other, the magnetic core limiting block 7122 is installed obliquely in the magnetic core limiting installation block 7121. Figure 4 At this time, the core limiting inclined surface 7125 is inclined from bottom to top in a direction away from the first core limiting magnetic member 7123 .

[0098] When the first core loading moving slider 7232 transports the empty core plate to the bottom of the core plate recovery space 712, the second core loading lifting assembly 722 drives the core plate to move upward. At this time, the side wall of the core plate abuts against the core limit inclined surface 7125, so that the core limit block 7122 rotates toward the inner wall of the core limit block accommodating groove, thereby ensuring that the core plate can move upward and be located above the core limit block 7122.

[0099] Then the second core loading lifting assembly 722 begins to descend. Due to the mutual repulsion between the first core limiting magnetic component 7123 and the second core limiting magnetic component 7124, the top of the core limiting block 7122 passes through the core limiting block accommodating groove and supports the core plate, thereby limiting the unloaded core plate within the core plate recovery space 712.

[0100] The first magnetic core loading and moving assembly 723 also includes a first magnetic core loading and moving cylinder, and the driving end of the first magnetic core loading and moving cylinder is fixedly connected to the first magnetic core loading and moving slider 7232; the second magnetic core loading and lifting assembly 722 also includes a second magnetic core loading and moving cylinder, and the driving end of the second magnetic core loading and moving cylinder is fixedly connected to the second magnetic core loading and moving slider 7242.

[0101] It should be noted that the first magnetic core loading and moving assembly 723 also includes a first magnetic core loading and moving cylinder as a power source. When the first magnetic core loading and moving cylinder is started, it can drive the first magnetic core loading and moving slider 7232 to slide back and forth on the first magnetic core loading and moving guide rail 7231, thereby transporting the magnetic core plate with the magnetic core to the bottom of the first magnetic core transfer robot assembly 731, and then transporting the empty magnetic core plate to the bottom of the magnetic core plate recovery space 712, thereby completing the transportation of the magnetic core plate.

[0102] The second magnetic core loading moving cylinder is used as a power source. When the second magnetic core loading moving cylinder is started, the second magnetic core loading moving slider 7242 can be driven to move back and forth on the second magnetic core loading moving guide rail 7241, thereby completing the magnetic core moving process of transporting the magnetic core to the vicinity of the positioning carrier. At this time, the arrangement of the first magnetic core loading moving cylinder and the second magnetic core loading moving cylinder can improve the degree of automation of the magnetic core moving mechanism 72 in this solution.

[0104] When the first magnetic core transfer robot assembly 731 transfers the magnetic cores on the magnetic core plate to multiple first magnetic core loading limit parts 72421 on the second magnetic core loading moving slider 7242 respectively, and then starts the magnetic core loading limit cylinder 72423, the magnetic core loading limit cylinder 72423 drives the second magnetic core loading limit part 72422 to move, so that the first magnetic core loading limit part 72421 and the second magnetic core loading limit part 72422 jointly clamp the magnetic core to ensure that the magnetic core will not be displaced during the movement of the second magnetic core loading moving slider 7242.

[0105] The first magnetic core transfer robot assembly 731, the second magnetic core transfer robot assembly and the stacking device 3 have the same structure; the stacking device 3 includes a first stacking guide rail 31, a second stacking guide rail 32, a third stacking guide rail 33 and a second stacking robot 35, the length direction of the first stacking guide rail 31 is the front-to-back direction, the first stacking guide rail 31 is slidably connected with a first stacking slider 36, the first stacking guide rail 31 is installed with a first stacking cylinder 311, and the driving end of the first stacking cylinder 311 is fixedly connected with the first stacking slider 36;

Two stacking devices 3 are provided, and the multiple guide rails between the two stacking devices 3 are spliced ​​to form a square structure. The two stacking devices 3 simultaneously assemble the magnetic cores on the multiple positioning carriers.

[0109] Among them, the first stacking cylinder 311, the second stacking cylinder 321 and the third stacking cylinder 331 are activated according to the position of the magnetic core, so that the first stacking slider 36 moves forward and backward on the first stacking rail 31 to determine the front and rear position of the first stacking manipulator 34 on the rack 1. Then the second stacking slider 37 slides left and right on the second stacking rail 32 to determine the left and right position of the first stacking manipulator 34 on the rack 1. Finally, the third stacking slider 38 moves up and down on the vertical third stacking rail 33 to determine the height of the first stacking manipulator 34, thereby adjusting the position of the first stacking manipulator 34 in multiple directions to ensure that the first stacking manipulator 34 is located directly above the magnetic core.

[0110] The second stacking manipulator 35 first clamps the nearest magnetic core, and then starts the third stacking cylinder 331 to drive the first stacking manipulator 34 to clamp a single magnetic core, and then the first stacking manipulator 34 moves to the vicinity of the second stacking manipulator 35 to stack the two magnetic cores. The first stacking manipulator 34 can also drive the magnetic cores to move back and forth to increase the viscosity between the two adjacent magnetic cores.

[0111] By repeating the above operation, the first stacking robot 34 can stack the multiple magnetic cores on the positioning carrier, thereby completing the process of assembling the magnetic cores. Thereafter, the first stacking robot 34 clamps the assembled magnetic cores and places them on a specific position of the positioning carrier, which can facilitate the encapsulation device 4 to encapsulate the assembled magnetic cores.

[0112] It is worth noting that the first magnetic core transfer robot assembly 731 and the second magnetic core transfer robot assembly of this solution have the same structure as the stacking device, and are both provided with guide rails in three directions, ensuring that the first magnetic core transfer robot assembly 731 and the second magnetic core transfer robot assembly can clamp the magnetic core at multiple angles, thereby completing the transfer of the magnetic core. In addition, the first magnetic core transfer robot assembly 731 and the second magnetic core transfer robot assembly are also provided with a magnetic core loading suction cup 7310, which can replace the traditional clamp to reduce the problem of loss of the magnetic core during the transfer process.

[0113] The coil feeding device 81 includes a coil feeding conveying assembly 811 and a coil feeding manipulator assembly 812, wherein the coil feeding conveying assembly 811 is used to convey the coil to one side of the positioning carrier 01, and the coil feeding manipulator assembly 812 is used to clamp the coil onto the positioning carrier 01; the coil assembling device 82 is provided with a first coil assembling manipulator assembly 821 and a second coil assembling manipulator assembly 822, wherein the first coil assembling manipulator assembly 821 is used to assemble the magnetic core and the coil, and the second coil assembling manipulator assembly 822 is used to horizontally clamp the coil to limit the rotation of the coil;

[0114] The flipping device 83 includes a transformer semi-finished product clamping assembly 831 and an upper frame flipping assembly 832. The upper frame flipping assembly 832 is used to flip the upper frame so that the front side of the upper frame faces upward and place the upper frame on top of the coil. The transformer semi-finished product clamping assembly 831 is used to horizontally clamp the coil.

[0115] When the positioning carrier 01 is located before the coil feeding device 81, the positioning carrier 01 is sequentially provided with an upper frame, a lower frame and a magnetic core. The assembly steps of the transformer generally include: 1. Placing the coil on the lower frame; 2. Then placing the magnetic core in the coil; 3. Finally placing the upper frame on the coil. When the positioning carrier 01 is located in the coil feeding device 81, the coil feeding conveying assembly 811 conveys the coil to the vicinity of the positioning carrier 01, and then the coil feeding manipulator assembly 812 clamps the coil onto the lower frame, thereby completing the first step of assembling the transformer. When the positioning carrier 01 is conveyed to the coil assembly device 82, the second coil assembly assembly horizontally clamps the coil to limit the movement of the coil, and then the first coil assembly assembly places the magnetic core in the coil, thereby completing the second step of assembling the semi-finished magnetic core.

[0116] The positioning carrier 01 continues to be transported to the bottom of the flipping device 83. At this time, the transformer semi-finished product clamping assembly 831 horizontally clamps the coil, the upper frame flipping assembly 832 flips the upper frame, and then places the upper frame on the top of the coil, thereby completing the third step of assembling the semi-finished magnetic core.

[0117] At this time, the coil feeding device 81, the coil assembling device 82 and the turning device 83 cooperate with each other to automatically assemble the various components of the transformer to form a semi-finished transformer, which solves the problem of traditional manual assembly, low assembly efficiency and high cost.

[0118] The coil feeding conveying assembly 811 includes a coil feeding motor 8111, a coil feeding conveyor belt 8112, a coil feeding limit plate 8113 and a coil feeding pressure plate 8114. The coil feeding motor 8111 is used to drive the coil feeding conveyor belt 8112. The coil feeding limit plates 8113 are installed on both ends of the left and right ends of the coil feeding conveyor belt 8112. The length direction of the coil feeding limit plate 8113 is consistent with the conveying direction of the coil feeding conveyor belt 8112. The coil feeding pressure plate 8114 is installed above the output end of the coil feeding conveyor belt 8112, and the two ends of the coil feeding pressure plate 8114 are fixedly connected to the two coil feeding limit plates 8113.

[0119] The coil feeding motor 8111 is started, and the coil feeding motor 8111 can drive the coil feeding conveyor belt 8112 to start transporting the coil. Since the input end of the coil feeding conveyor belt 8112 is connected to the coil silo, the coil in the coil silo can be transported to one side of the positioning carrier plate 01 under the action of the coil feeding conveyor belt 8112.

[0120] It is worth noting that the coil feeding limit plates 8113 are horizontally installed on both sides of the coil feeding conveyor belt 8112, which can limit the range of movement of the coil on the coil feeding conveyor belt 8112. Among them, this solution can also limit the spacing between the two coil feeding limit plates 8113, so that multiple coils are arranged in a row. Then the output end of the coil feeding conveyor belt 8112 is also provided with a horizontal coil feeding pressure plate 8114, referring to Figure 2 The coil feeding pressure plate 8114 can prevent the coil from continuing to move forward, so that the coil stays at the output end of the coil feeding conveyor belt 8112, thereby facilitating the coil feeding robot assembly 812 to clamp and feed the coil.

[0121] The coil feeding manipulator assembly 812 includes a coil feeding moving guide rail 8121, a coil feeding moving slider 8122, a coil feeding lifting member 8123 and a coil feeding manipulator 8124;

[0122] One end of the coil loading movable guide rail 8121 is located above the coil loading conveyor belt 8112, and the other end of the coil loading movable guide rail 8121 is located above the positioning carrier 01. A coil loading power piece 8125 is fixedly installed at the end of the coil loading movable guide rail 8121, and the driving end of the coil loading power piece 8125 is fixedly connected to the coil loading movable slider 8122, and the coil loading movable slider 8122 is slidably connected to the coil loading movable guide rail 8121. A coil loading lifting piece 8123 is provided on the top of the coil loading movable slider 8122, and the lifting end of the coil loading lifting piece 8123 is fixedly connected to the coil loading manipulator 8124.

[0123] The coil feeding power part 8125 is started, which can drive the coil feeding moving slider 8122 to move on the coil feeding moving guide rail 8121, so that the coil feeding manipulator 8124 is located above the output end of the coil feeding conveyor belt 8112. Then the coil feeding lifting part 8123 is started, and the coil feeding lifting part 8123 can drive the coil feeding manipulator 8124 to move in the vertical direction, ensuring that the coil feeding manipulator 8124 can clamp the coil downward.

[0124] Continue to start the coil loading lifting member 8123 and the coil loading power member 8125, so that the coil loading robot 8124 can move above the positioning carrier 01, and then place the coil on the lower frame, thereby completing the first step of assembling the transformer.

[0125] It is worth noting that the coil feeding lifting member 8123 and the coil feeding power member 8125 are both cylinders, which have a simple structure and are widely used and can be replaced and repaired in a timely manner. The first coil assembly manipulator assembly 821 includes a first coil assembly rail 8211, a second coil assembly rail 8212, a third coil assembly rail 8213 and a first coil assembly manipulator 8210;

[0126] The first coil assembly guide rail 8211 is in the front-to-back direction, and the first coil assembly guide rail 8211 is fixedly installed with a first coil assembly power part 8217, and the driving end of the first coil assembly power part 8217 is fixedly installed with a first coil assembly slider 8214, and the first coil assembly slider 8214 is slidably connected to the first coil assembly guide rail 8211, and the first coil assembly slider 8214 is fixedly connected to the second coil assembly guide rail 8212, and the second coil assembly guide rail 8212 is in the left-right direction, and the second coil assembly guide rail 8212 is fixedly installed with a second coil assembly power part 8218, and the second coil assembly power part 8218 A second coil assembly slider 8215 is fixedly installed on the driving end, and the second coil assembly slider 8215 is slidably connected to the second coil assembly guide rail 8212. The second coil assembly slider 8215 is fixedly installed with a vertical third coil assembly guide rail 8213, and the third coil assembly guide rail 8213 is fixedly installed with a third coil assembly power part 8219. The driving end of the third coil assembly power part 8219 is fixedly installed with a third coil assembly slider 8216, and the third coil assembly slider 8216 is slidably connected to the third coil assembly guide rail 8213. The third coil assembly slider 8216 is fixedly installed with a first coil assembly robot 8210.

[0127] When the first coil assembly power part 8217 is started, the first coil assembly slider 8214 can be driven to move in the front-to-back direction. When the second coil assembly power part 8218 is started, the second coil assembly slider 8215 can be driven to move in the left-right direction. When the third coil assembly power part 8219 is started, the third coil assembly slider 8216 can be driven to move in the vertical direction. Therefore, the first coil assembly power part 8217, the second coil assembly power part 8218 and the third coil assembly power part 8219 cooperate with each other, so that the first coil assembly manipulator 8210 can move freely in multiple directions, so that the magnetic core can be placed in the coil.

[0128] The second coil assembly robot component 822 and the transformer semi-finished product clamping component 831 have the same structure, and both the second coil assembly robot component 822 and the transformer semi-finished product clamping component 831 include a semi-finished product clamping power member 8311, a semi-finished product clamping mounting frame 8312 and a semi-finished product clamping robot 8313, the driving end of the semi-finished product clamping power member 8311 is fixedly connected to the semi-finished product clamping mounting frame 8312, the top of the semi-finished product clamping mounting frame 8312 is fixedly connected to the semi-finished product clamping robot 8313, and the semi-finished product clamping robot 8313 is used to horizontally clamp the coil;

[0129] The driving direction of the semi-finished product clamping power member 8311 is perpendicular to the conveying direction of the positioning carrier 01; the upper skeleton flipping assembly 832 includes a first upper skeleton flipping guide rail 8321, a second upper skeleton flipping guide rail 8322 and an upper skeleton flipping manipulator 8323;

[0130] The first upper skeleton flipping guide rail 8321 is in the left-right direction, and the first upper skeleton flipping guide rail 8321 is installed with a first upper skeleton flipping power piece 8324, the driving end of the first upper skeleton flipping power piece 8324 is fixedly connected to the first upper skeleton flipping slider 8327, the first upper skeleton flipping slider 8327 is slidably connected to the first upper skeleton flipping guide rail 8321, the first upper skeleton flipping slider 8327 is fixedly installed with a vertical second upper skeleton flipping guide rail 8322, the second upper skeleton flipping guide rail 8322 is installed with a second upper skeleton flipping power piece 8325, the driving end of the second upper skeleton flipping power piece 8325 is fixedly connected to the second upper skeleton flipping slider 8328, the second upper skeleton flipping slider 8328 is slidably connected to the second upper skeleton flipping guide rail 8322, the second upper skeleton flipping slider 8328 is provided with a third skeleton flipping power piece, the driving end of the third skeleton flipping power piece is fixedly connected to the upper skeleton flipping manipulator 8323, and the upper skeleton flipping manipulator 8323 and the second upper skeleton flipping slider 8328 rotate relative to each other.

[0131] It is worth noting that when the semi-finished product clamping power member 8311 is started, it can drive the semi-finished product clamping mounting frame 8312 and the semi-finished product clamping manipulator 8313 to move together, and then drive the semi-finished product clamping manipulator 8313 to clamp the coil. Since the driving direction of the semi-finished product clamping power member 8311 is limited in this solution, the semi-finished product clamping manipulator can only clamp the coil in the horizontal direction, which limits the position deviation of the coil during the assembly process.

[0132] When the first upper frame flipping power piece 8324 is started, the first upper frame flipping slider 8327 can be driven to move back and forth on the first upper frame flipping guide rail 8321, so that the upper frame flipping manipulator 8323 can move left and right above the positioning carrier 01. When the second upper frame flipping power piece 8325 is started, the second upper frame flipping slider 8328 can be driven to move along the vertical direction on the second upper frame flipping guide rail 8322. Therefore, through the cooperation between the first upper frame flipping power piece and the second upper frame flipping power piece 8325, the upper frame flipping manipulator can move randomly above the positioning carrier 01 and clamp the upper frame.

[0133] Return to start the third frame flipping power piece, the third frame flipping power piece can drive the upper frame flipping manipulator 8323 to flip over the positioning carrier 01, so that the front of the upper frame faces upward. Then continue to start the first upper frame flipping power piece 8324 and the second upper frame flipping power piece 8325, so that the upper frame flipping manipulator 8323 can place the upper frame on the top of the coil, thereby completing the last step of assembling the semi-finished transformer.

[0134] The positioning carrier plate 01 includes a base plate 011, and the base plate 011 is provided with an upper skeleton mounting structure 012, a magnetic core mounting groove 013, a lower skeleton mounting structure 014 and a pressing assembly 015 from front to back; the upper skeleton mounting structure 012 and the lower skeleton mounting structure 014 are both provided with a positioning pin assembly 0121 and a skeleton mounting groove 0122, the skeleton mounting groove 0122 is used to place the upper skeleton or the lower skeleton, and the positioning pin assembly 0121 is used to limit the upper skeleton or the lower skeleton to move in the corresponding skeleton mounting groove 0122; the magnetic core mounting groove 013 is used to place the magnetic core, and the pressing assembly 015 is used to press the assembled transformer.

[0135] A positioning carrier plate 01 of the present scheme, the skeleton mounting groove 0122 of the upper skeleton mounting structure 012 can be used to place the upper skeleton, and the positioning pin assembly 0121 can limit the position of the upper skeleton to prevent the upper skeleton from moving in the skeleton mounting groove 0122; similarly, the skeleton mounting groove 0122 in the lower skeleton mounting structure 014 can be used to place the lower skeleton, and the positioning pin assembly 0121 can limit the movement of the lower skeleton in the skeleton mounting groove 0122.

[0136] Moreover, the pressing component 015 can press the assembled transformer, further reducing the relative sliding of the parts and the bottom plate 011 when the bottom plate 011 moves. At this time, the positioning pin component 0121 can lock the frame in the corresponding frame installation groove 0122, and the pressing component 015 can limit the assembled transformer. The positioning pin component 0121 and the pressing component 015 cooperate with each other, which can further solve the problem that when the traditional transformer carrier plate moves, the parts on the transformer will slide relative to the transformer carrier plate, which seriously reduces the assembly efficiency of the production line.

[0137] The upper frame installation structure 012 is the same as the lower frame installation structure 014. Both the upper frame installation structure 012 and the lower frame installation structure 014 further include a frame limiting portion 0123. The front end of the frame installation groove 0122 is provided with the frame limiting portion 0123. The middle of the frame limiting portion 0123 is provided with a frame activity space 01231. The front end of the frame activity space 01231 passes through the frame limiting portion 0123. The rear end of the frame activity space 01231 is connected to the frame. The skeleton mounting groove 0122 is connected, and the positioning pin assembly 0121 includes a limit member 01211, and the limit member 01211 can be movably inserted into the bottom of the skeleton activity space 01231, and the skeleton activity space 01231 is used for allowing the skeleton to move along the front-to-back direction to the skeleton mounting groove 0122; when the limit member 01211 is movably inserted into the skeleton activity space 01231, the limit member 01211 limits the relative movement of the skeleton and the skeleton mounting groove 0122.

[0138] The manipulator on the production line places the skeleton on the skeleton limiting part 0123, at which time the hook at the bottom of the skeleton moves into the skeleton activity space 01231 and vertically presses the limiting part 01211. Then the manipulator on the production line moves the skeleton on the skeleton limiting part 0123, at which time the bottom wall of the skeleton moves in the skeleton limiting part 0123, and the hook at the bottom and the top of the limiting part 01211 move and abut with the skeleton. When the skeleton is located in the skeleton installation groove 0122, the limiting part 01211 is separated from the hook at the bottom of the skeleton. At this time, the limiting part 01211 is reset and moves into the skeleton activity space 01231, and the side wall of the hook abuts against the side wall of the limiting part 01211, thereby preventing the skeleton and the skeleton installation groove 0122 from moving relative to each other, and then locking the skeleton in the skeleton installation groove 0122.

[0139] If the skeleton in the skeleton installation groove 0122 needs to be grabbed on the production line, it is only necessary to press the limit member 01211 downward so that the hook at the bottom of the skeleton can move and abut against the top of the limit member 01211 to contact the limit member 01211 to limit the skeleton.

[0140] The positioning pin assembly 0121 also includes a base 01212 and an elastic member 01213. The top wall of the base 01212 is fixedly connected to the bottom wall of the skeleton limiting portion 0123. The base 01212 is provided with a vertical limiting member 01211 accommodating groove. The limiting member 01211 accommodating groove is slidably connected to the limiting member 01211. The base 01212 is provided with an elastic member 01213 accommodating groove. The top of the elastic member 01213 accommodating groove is connected to the bottom of the limiting member 01211 accommodating groove. The elastic member 01213 is fixedly connected to the bottom wall of the elastic member 01213 accommodating groove and the bottom of the limiting member 01211.

[0141] Specifically, when the frame is located on the frame limiting portion 0123, the hook at the bottom of the frame extends into the frame activity space 01231 and presses downward against the limiting member 01211, so that the elastic member 01213 is compressed. When the hook at the bottom of the frame and the limiting member 01211 separate, the elastic member 01213 begins to reset, driving the limiting member 01211 to move and penetrate into the bottom of the frame activity space 01231, so that the side wall of the hook abuts against the side wall of the limiting member 01211, thereby ensuring that the limiting member 01211 can play a role in limiting the movement of the frame.

[0142] The pressing assembly 015 includes a pressing guide rail 0151, a pressing slider 0152, a pressing block 0153 and a pressing cylinder. The pressing guide rail 0151 and the pressing cylinder are installed at the rear end of the base plate 011. The length direction of the pressing guide rail 0151 is parallel to the length direction of the base plate 011. The pressing guide rail 0151 is slidably connected to the pressing slider 0152. The pressing cylinder is installed at the rear end of the base 01212. The driving end of the pressure cylinder is fixedly connected to the pressure slider 0152, and the driving end of the pressure cylinder is used to drive the pressure slider 0152 to slide along the pressure guide rail 0151. The pressure slider 0152 is fixedly installed with the pressure block 0153. The length direction of the pressure block 0153 is parallel to the length direction of the pressure guide rail 0151, and the end of the pressure block 0153 away from the pressure slider 0152 is close to or away from the parts of the transformer.

[0143] When the robot on the production line starts to assemble the transformer, the coil and the upper frame are stacked in sequence in the lower frame installation mechanism. When the bottom plate 011 is gently moved, the coil and the upper frame may move relative to each other or collapse. At this time, the pressing cylinder (not shown in the figure) is started, and the driving end of the pressing cylinder can drive the pressing slider 0152 to move on the pressing guide rail 0151. Since the pressing slider 0152 is fixedly installed with a pressing block 0153, the pressing cylinder can drive the pressing block 0153 to move forward, thereby ensuring that the pressing block 0153 can press the coil and the upper frame.

[0144] The plurality of pressing blocks 0153 are arranged in a pyramid shape. Preferably, in this embodiment, three pressing blocks 0153 are provided, two of which are located at the bottom of the pressing slider 0152, and the other one is located at the top of the pressing slider 0152, so that the ends of the two pressing sliders 0152 at the bottom can press the coil horizontally, reducing the occurrence of the coil moving on the bottom plate 0111.

[0145] The pressing block 0153 at the top can press the upper frame horizontally, which can not only reduce the relative movement between the upper frame and the coil, but also prevent the entire assembled transformer from moving on the bottom plate 0111.

[0146] The magnetic core installation groove 013 is provided with a plurality of magnetic core installation grooves 013, and the plurality of magnetic core installation grooves 013 are evenly arranged side by side at the left and right ends of the bottom plate 011, and the magnetic core installation groove 013 is used to store a single magnetic core; the rear end of the bottom plate 011 is also provided with an assembly magnetic core positioning component 016, and the assembly magnetic core positioning component is used to store the assembled magnetic core. It is worth noting that the number of magnetic core installation grooves 013 in this scheme is not limited, and can be adjusted and set according to actual production needs. At this time, the robot on the production line can assemble the magnetic core in the magnetic core installation groove 013, and then grab the assembled magnetic core, and place the assembled magnetic core in the assembly magnetic core positioning component 016, so that the position of the assembled magnetic core can be limited, thereby avoiding the relative movement of the assembled magnetic core and the bottom plate 011, resulting in position deviation.

[0147] The assembled magnetic core positioning assembly 016 is provided with two groups, and the two groups of the assembled magnetic core positioning assembly 016 are respectively located at the left and right ends of the pressing assembly 015; the assembled magnetic core positioning assembly 016 includes four vertical limiting columns 0161, and the limiting columns 0161 are vertically installed on the bottom plate 011, and the space surrounded by the four limiting columns 0161 is used to store the assembled magnetic core.

[0148] This solution limits the number of assembled magnetic core positioning components 016 according to the structure of the transformer. In this embodiment, two groups of assembled magnetic core positioning components 016 are preferably used. The left and right ends of the pressing component 015 are both provided with assembled magnetic core positioning components 016, which can optimize the layout on the bottom plate 011, so that the bottom plate 011 can realize multiple functions in a limited space.

[0149] Among them, the assembled magnetic core positioning component 016 includes four limit columns 0161, and the multiple limit columns 0161 respectively abut the four end points of the assembled magnetic core. This simple structure can not only be quickly installed on the base plate 011, but also limit the position of the assembled magnetic core, further avoiding the relative movement of the assembled magnetic core and the base plate 011.

[0150] The top of the limiting column 0161 is provided with an inclined surface 0162. The inclined surface 0162 can play a guiding role. When the mechanical arm grabbing the assembled magnetic core has a position deviation above the limiting column 0161, the inclined surface 0162 can guide the mechanical arm to move, ensuring that the mechanical arm can place the assembled magnetic core in the space surrounded by the four limiting columns 0161.

[0151] A transformer assembly method comprises the following steps: step 1, a conveying device conveys a positioning carrier plate 01; step 2, a magnetic core loading and transfer device 7 loads the magnetic core onto the positioning carrier plate 01; step 3, a skeleton loading device 5 loads the skeleton onto the positioning carrier plate 01; step 4, a glue spraying device 2 sprays glue on the skeleton and the magnetic core; step 5, a stacking device 3 stacks a plurality of magnetic cores into an assembled magnetic core; step 6, an air gap sheet loading device 6 loads the air gap sheet onto the positioning carrier plate 01; step 7, a glue coating device 4 coats the assembled magnetic core with glue; step 8, a coil loading device 81 loads the coil onto the positioning carrier plate 01; step 9, a coil assembling device 82 places the assembled magnetic core that has been coated with glue in the coil; step 10, a flipping device 83 places the skeleton on the coil.

[0152] The transformer assembly method of this solution is used in conjunction with a transformer automatic production line to improve the transformer assembly efficiency, automatically assemble the transformer, and further solve the problems of low efficiency and low production capacity of traditional magnetic core assembly.
