[0045] An embodiment of the present invention provides a fully automatic magnetic core pad printing machine, such as Figure 1 , Figure 2a-2e , Figure 3a-3e , Figure 4a-4e as well as Figure 5As shown, it includes a machine platform 100 and a magnetic core loading device 200, a magnetic core pad printing device 300, a magnetic core drying device 400 and a magnetic core unloading device 500 arranged on the machine platform 100. In order to facilitate the movement of the magnetic core fully automatic pad printing machine, a roller 101 can be arranged at the bottom of the machine platform 100.

[0046] The magnetic core loading device 200 includes a vibration disk 210, a feeding track 240 and a screening track 230 connected to the feeding track 240. A vibration disk track 220 is arranged in the vibration disk 210, and the vibration disk track 220 continuously transports the magnetic cores outward; the vibration disk track 220, the screening track 230 and the feeding track 240 are connected in sequence along the feeding direction, and the screening track 230 is used to receive the magnetic cores output by the vibration disk track 220, screen the magnetic cores, and screen out the target magnetic cores 11. The target magnetic cores 11 are magnetic cores with a uniform arrangement direction. The screening track 230 also transports the target magnetic cores 11 to the feeding track 240. In this way, the magnetic cores transported to the magnetic core pad printing device 300 have a uniform arrangement direction, which is convenient for pad printing operations.

[0047] The magnetic core pad printing device 300 includes a transport track 310 docked with the feeding track 240 and a pad printing mechanism 320 and a material dividing mechanism 330 respectively arranged on both sides of the transport track 310. The material dividing mechanism 330 is used to separate adjacent magnetic cores on the transport track 310 and expand the distance between two adjacent magnetic cores. The pad printing mechanism 320 is used to perform pad printing operations on the separated magnetic cores, which can avoid adhesion between two adjacent magnetic cores.

[0048] The magnetic core drying device 400 includes a rotating disk mechanism and a drying mechanism. The rotating disk mechanism is used to drive the magnetic core to rotate, and the drying mechanism is used to dry the magnetic core on the rotating disk mechanism. Since the magnetic core is dried during the rotation process, this drying method has a better drying effect compared to a linear drying channel.

[0049] The magnetic core unloading device 500 includes a blanking plate 510 and a receiving mechanism. The blanking plate 510 is used to receive the dried magnetic cores and make the magnetic cores fall into the receiving mechanism. The magnetic cores that have completed pad printing will be collected in the receiving mechanism.

[0050] The magnetic core loading device 200, the magnetic core pad printing device 300, the magnetic core drying device 400 and the magnetic core unloading device 500 of this embodiment can all be connected to the controller. The controller will send control signals to the magnetic core loading device 200, the magnetic core pad printing device 300, the magnetic core drying device 400 and the magnetic core unloading device 500 according to a preset control program, so that the magnetic core loading device 200, the magnetic core pad printing device 300, the magnetic core drying device 400 and the magnetic core unloading device 500 can coordinate their actions with each other.

[0051] Hereinafter, the magnetic core loading device 200 will be described in detail.

[0052] An embodiment of the present invention provides a magnetic core feeding device, such as Figure 2a-2e As shown, it includes a vibration plate 210, a vibrator 250, a feeding track 240, and a screening track 230 connected to the feeding track 240, and the feeding track 240 and the screening track 230 can be connected in an integrated manner. The vibration plate 210 is used to load magnetic cores, and it has a vibration plate track 220 for conveying magnetic cores, and the vibration plate track 220 conveys magnetic cores one by one continuously (since the vibration plate track 220 is a conventional component in the vibration plate 210, the present application does not illustrate the vibration plate track 220 in the vibration plate 210). The vibration plate track 220 can extend out of the vibration plate 210, and the vibration plate track 220, the screening track 230 and the feeding track 240 are arranged in sequence along the feeding direction. The magnetic core output from the vibration plate track 220 will pass through the screening track 230 and then move to the feeding track 240. The feeding track 240 can dock with the next station, so as to convey the magnetic core to the next station and realize automatic loading.

[0053] The vibrator 250 can be fixed at the bottom of the feeding track 240. Since the screening track 230 is connected to the feeding track 240, the vibrator 250 can drive the feeding track 240 and the screening track 230 to vibrate, and the feeding track 240 and the screening track 230 transport the magnetic cores by vibration. The feeding track 240 and the screening track 230 can usually be set to a linear type, and the vibrator 250 can be a linear vibration device correspondingly.

[0054] The screening track 230 includes a track plate extending along the feeding direction, and a track groove 231 is provided on the surface of the track plate to dock with the vibration plate track 220, and the magnetic core output by the vibration plate track 220 will enter the track groove 231. The track groove 231 includes a bottom wall 232 and a side wall 233 for receiving the magnetic core, the bottom wall 232 is inclined relative to the vertical direction, the height of the bottom wall 232 in the width direction gradually increases, and has a side with a lower height and a side with a higher height in the width direction, and the side wall 233 is provided on the side with a lower height of the bottom wall 232, so that the magnetic core will move above the connection position of the bottom wall 232 and the side wall 233.

[0055] The target magnetic core 11 and the non-target magnetic core 12 both move along the screening track 230, wherein the target magnetic core 11 is a magnetic core whose length direction is parallel to the feeding direction, and the non-target magnetic core 12 is a magnetic core whose length direction is not parallel to the feeding direction. A feeding trough 234 is provided on the bottom wall 232 for only the target magnetic core 11 to pass through, and the feeding trough 234 is docked with the feeding track 240, so that the target magnetic core 11 will enter the feeding trough 234 and move along the feeding trough 234 to the feeding track 240. The non-target magnetic core 12 cannot enter the feeding trough 234, and it continues to move along the track groove 231. Since a blanking notch 235 is provided on the side wall 233, the non-target magnetic core 12 will eventually fall from the blanking notch 235. Therefore, the feeding track 240 of this embodiment finally outputs magnetic cores arranged in the same direction, and the entire process is realized by mechanical automation, which greatly improves production efficiency.

[0056] For the use case where the magnetic core needs to face up, the present embodiment can also set a front and back screening mechanism on the vibration plate track 220, so that the magnetic core finally output by the vibration plate track 220 faces up. The front and back screening mechanism is already a prior art, and will not be described in detail in the present embodiment. The front orientation of the magnetic cores transported to the screening track 230 is unified, and after screening by the screening track 230, the magnetic cores finally output by the feeding track 240 all face up and are arranged along the length direction, which is more convenient for pad printing.

[0057] The magnetic core loading device of this embodiment may further include a machine table 100, and the vibration plate 210, the screening track 230 and the feeding track 240 may be fixed on the machine table 100. A first bracket 251 may be provided on the machine table 100, and the vibrator 250 may be fixed on the first bracket 251, so as to lift the screening track 230 and the feeding track 240 to a certain height so as to dock with the vibration plate track 220. A plurality of rollers 101 may be provided at the bottom of the machine table 100 so as to facilitate the movement of the entire magnetic core loading device.

[0058] In this embodiment, a protruding screening convex plate 236 is provided on the bottom wall 232. The screening convex plate 236, the bottom wall 232 and the side wall 233 together form a material trough 234, which is equivalent to a part of the track groove 231 forming the material trough 23, so that the target magnetic core 11 can enter the material trough 234 more smoothly.

[0059] In this embodiment, a material guiding slope 237 is provided at one end of the screening convex plate 236 close to the vibration plate track 220, and the material guiding slope 237 is configured such that: in the feeding direction, the distance of the material guiding slope 237 protruding from the bottom wall 232 gradually increases, and the non-target magnetic cores 12 that cannot enter the material trough 234 will gradually move away from the material trough 234 along the material guiding slope 237, and finally fall from the material dropping notch 235. This gradually protruding structure can effectively avoid material jamming and make the magnetic core transportation smoother.

[0060] Specifically, the guiding inclined surface 237 may be an arc-shaped structure, the surface of which is smoother, making it easier for the non-target magnetic core 12 to move.

[0061] At the same time, the guide slope 237 is closer to the vibration plate track 220 relative to the blanking notch 235. Therefore, before blanking, the target magnetic core 11 and the non-target magnetic core 12 have been separated, which can avoid the situation that the non-target magnetic core 12 cannot fall from the blanking notch 235.

[0062] Furthermore, the bottom wall 232 and the side wall 233 are arranged perpendicular to each other, and the cross-sectional shape of the track groove 231 can be "L"-shaped. This structure is more suitable for transporting magnetic cores with a shape similar to a rectangular structure, can be more consistent with the shape of the magnetic core, and is more convenient for transporting the magnetic core.

[0063] Furthermore, the track plate is arranged parallel to the bottom wall 232 , and thus the track plate is also arranged obliquely, which is more consistent with the structure of the obliquely arranged material chute 234 , making it easier for non-target magnetic cores 12 to fall from the blanking notch 235 .

[0064] When the track plate is set at an angle, considering that the inclined magnetic core is not conducive to the production operation of the next process, this embodiment can configure the track plate located on the feeding track 240 to gradually rotate along the feeding direction to a horizontal state. In this way, the magnetic core output by the feeding track 240 will be in a normal horizontal state, which is convenient for the next workstation to carry out production operations.

[0065] The vibration plate track 220 may include two vibration plate track plates 221, which are respectively arranged parallel to the bottom wall 232 and the side wall 233, and the upper surfaces of the two vibration plate track plates 221 are respectively flush with the bottom wall 232 and the side wall 233, so that the magnetic core can smoothly move from the vibration plate track 220 to the screening track 230. Therefore, the track structure of this embodiment is open, which can make material transportation smoother than the closed track structure.

[0066] In this embodiment, the feeding track 240 and the screening track 230 can be connected in an integrated manner, the track plate extends to the feeding track 240, and the trough 234 extends to the track plate located at the feeding track 240, so that the magnetic core will continue to move in the trough 234 and can eventually be output from the feeding track 240. The feeding track 240 is provided with a track baffle 241 extending along the extension direction of the trough 234, and the track baffle 241 covers at least a portion of the trough 234 located at the feeding track 240. Since the feeding track 240 is long, there may be magnetic cores that are mis-sorted or separated from the trough 234 during the movement process, and the track baffle 241 has a limiting effect on the magnetic cores in the trough 234, so that the magnetic cores are kept transported along their length direction and can prevent the magnetic cores from falling out of the trough 234.

[0067] In this embodiment, the magnetic core feeding device further includes a feeding mechanism, which includes a hopper 260, a feeding plate 270 and a vibration mechanism 280. The hopper 260 has an opening at the bottom, which is located above the feeding plate 270, and the feeding plate 270 has a feeding trough, and the magnetic cores in the hopper 260 can fall from the opening into the feeding trough. The feeding trough has a feeding trough outlet for the magnetic core to move out of the feeding trough, and the feeding trough outlet is located above the vibration disk 210. The vibration mechanism 280 is fixed on the feeding plate 270 and drives the feeding plate 270 to vibrate, so that the magnetic core on the feeding plate 270 moves to the lower feeding trough outlet, and the magnetic core finally falls into the vibration disk 210, thereby replenishing the vibration disk 210, avoiding the magnetic core feeding device from stopping feeding and affecting the production efficiency. The driving principle of the vibration mechanism 280 can be the same as the vibrator 250 in the above embodiment. In this embodiment, a second bracket 261 is disposed on the machine 100 , and the feeding mechanism can be fixed on the second bracket 261 .

[0068] Furthermore, the feeding mechanism also includes a controller and a magnetic core detection mechanism 292 for detecting whether the magnetic core in the vibration disk 210 is sufficient. The magnetic core detection mechanism 292 and the vibration mechanism 280 are both electrically connected to the controller. In the default state, the vibration mechanism 280 does not work, so the magnetic core can not be delivered to the vibration disk 210. When the magnetic core detection mechanism 292 detects that the magnetic core of the vibration disk 210 is insufficient, it sends an induction signal to the controller. The controller sends a control signal to the vibration mechanism 280 based on the induction signal, so that the vibration mechanism 280 starts working, and the magnetic core can fall into the vibration disk 210. This can realize automatic feeding without excessive manual supervision, which is more intelligent.

[0069] In this embodiment, the bottom wall of the vibration disk 210 gradually bulges in the radial direction pointing to the center of the vibration disk 210, and the magnetic core will more easily slide away from the center of the vibration disk 210, thereby accumulating near the periphery of the vibration disk 210. Since the vibration disk track 220 is usually spiral-shaped and distributed near the periphery of the vibration disk 210, it is easier for the magnetic core to enter the vibration disk track 220.

[0070] The magnetic core detection mechanism 292 is an infrared distance sensor. A detection fixing rod 291 can be provided on the second bracket 261. One end of the detection fixing rod 291 can be fixed on the second bracket 261, and the other end is fixed with the infrared distance sensor. The infrared distance sensor irradiates light to the bottom of the vibration plate 210. When there is no magnetic core at the irradiation position of the infrared distance sensor, the distance detected by the infrared distance sensor becomes smaller, thereby judging that the vibration plate 210 is short of material.

[0071] In this embodiment, the feed slot 234 is configured as follows: the width of the feed slot 234 matches the width of the magnetic core, and can be slightly larger than the width of the magnetic core, and the width of the feed slot 234 is smaller than the length of the magnetic core. Therefore, when the length direction of the magnetic core is parallel to the extension direction of the feed slot 234, it can enter the feed slot 234, and when the length direction of the magnetic core is not parallel to the extension direction of the feed slot 234, it cannot enter the feed slot 234, thereby realizing the screening of the magnetic core sorting direction.

[0072] In this embodiment, a receiving box 222 for receiving the magnetic cores dropped from the material dropping notch 235 is provided below the material dropping notch 235, so that non-target magnetic cores 12 will not fall directly to the ground, and the collected magnetic cores can be put back into the vibration plate 210 to reduce material loss.

[0073] Furthermore, the receiving box 222 can be connected to the vibration plate 210, and the bottom of the receiving box 222 is provided with a drop slope to guide the magnetic core to the vibration plate 210. The magnetic core falling into the receiving box 222 can slide along the drop slope into the vibration plate 210, and then automatically fall back to the vibration plate 210 without manual handling, which is more intelligent.

[0074] Hereinafter, the magnetic core transfer printing device 300 will be described in detail.

[0075] An embodiment of the present invention provides a magnetic core transfer printing device, such as Figure 3a-3e As shown, it includes a transport track 310 and a pad printing mechanism 320 and a material dividing mechanism 330 respectively arranged on both sides of the transport track 310. A cache station 311 and a pad printing station 312 are sequentially arranged on the transport track 310 along the core conveying direction. The cache station 311 is used to receive the magnetic cores conveyed from the outside and cache the magnetic cores. The pad printing mechanism 320 will perform pad printing operations on the magnetic cores on the pad printing station 312.

[0076] The material distribution mechanism 330 includes a base plate 332, a clamping drive 333, a fork drive 334, a clamping plate 335 and a fork plate 336, and the clamping drive 333, the fork drive 334, the clamping plate 335 and the fork plate 336 are all arranged on the base plate 332. The clamping drive 333 is used to drive the clamping plate 335 to approach or move away from the transport track 310, and the position of the clamping plate 335 corresponds to the position of the buffer station 311. When the clamping drive 333 drives the clamping plate 335 to approach the transport track 310, the clamping plate 335 positions the magnetic core of the buffer station 311 to avoid the magnetic core from being offset in the process of moving to the pad printing station 312. At the same time, the clamping drive 333 can also drive the clamping plate 335 to move away from the transport track 310 and reset, so as to facilitate positioning of the next batch of magnetic cores.

[0077] The fork material driver 334 is used to drive the fork material plate 336 to approach or move away from the transport track 310. The position of the fork material plate 336 corresponds to the position of the pad printing station 312. When the fork material driver 334 drives the fork material plate 336 to approach the transport track 310, the fork material plate 336 separates the magnetic cores on the pad printing station 312, thereby increasing the distance between adjacent magnetic cores. At the same time, the fork material driver 334 can also drive the fork material plate 336 to move away from the transport track 310 and reset it, so as to separate the next batch of magnetic cores.

[0078] The pad printing mechanism 320 includes a pad printing head 321. After the brush head on the pad printing head 321 is dipped in the slurry, it can be moved to the top of the pad printing station 312, and then the silver slurry is pad printed on the surface of the magnetic core after separation. The distance between the two adjacent magnetic cores after separation is large enough. The pad printing mechanism performs the pad printing operation after the magnetic cores are separated, which can avoid the adhesion of adjacent magnetic cores and effectively improve the yield rate of the magnetic cores.

[0079] A bottom plate driving mechanism is provided at the bottom of the bottom plate 332, which can drive the clamping plate 335 to move the magnetic core from the buffer station 311 to the pad printing station 312, and drive the fork plate 336 to move the magnetic core out of the pad printing station 312 to realize automatic feeding.

[0080] The above-mentioned clamping material driver 333, fork material driver 334, transport track 310, pad printing mechanism 320 and bottom plate driving mechanism can all be electrically connected to the controller. The controller will control the above-mentioned clamping material driver 333, fork material driver 334, transport track 310, pad printing mechanism 320 and bottom plate driving mechanism to coordinate actions according to a preset control program to complete the pad printing of the magnetic core.

[0081] In this embodiment, a plurality of first fork rods 3351 extending toward the direction close to the transport track 310 are provided on the clamping plate 335. The first fork rods 3351 are distributed along the conveying direction of the magnetic cores on the transport track 310, and a first positioning groove 3350 for accommodating the magnetic cores is formed between two adjacent first fork rods 3351. Since the magnetic cores on the transport track 310 are arranged in rows, the first fork rods 3351 can be inserted between two adjacent magnetic cores, which positions the magnetic cores in the first positioning grooves 3350 to prevent the magnetic cores from moving at will.

[0082] Furthermore, the width of the first fork rod 3351 gradually decreases in its extension direction, that is, the width of the first fork rod 3351 gradually increases from the outwardly extending end to its tail end, and the end with a smaller width is easier to insert between two adjacent magnetic cores, thereby positioning the magnetic cores.

[0083] In this embodiment, a plurality of second fork rods extending in the direction close to the transport track 310 are provided on the fork plate 336. The second fork rods are distributed along the conveying direction of the magnetic cores on the transport track 310, and a second positioning groove 3360 for accommodating the magnetic cores is formed between two adjacent second fork rods. The end of the second fork rod has a pointed head, which may be in a triangular structure, and its width gradually decreases in the extending direction of the second fork rod. The pointed head has a material dividing slope 3361, and the length of the second fork rods distributed in the material dividing direction gradually decreases. In the process of inserting the pointed head into two adjacent magnetic cores, the material dividing slope 3361 gradually pushes the magnetic core in a direction parallel to the conveying direction of the magnetic core, so that the distance between the two adjacent magnetic cores increases, and the direction in which the material dividing slope 3361 pushes the magnetic core is the material dividing direction. The length of the second fork rods distributed in the material distribution direction gradually decreases, so when the second fork rods approach the transport track 310, the second fork rod with the longest length is first inserted between the corresponding two magnetic cores and pushes the magnetic cores in the material distribution direction, and then the second fork rods gradually enter between the corresponding two magnetic cores, thereby gradually expanding the distance between the magnetic cores in an orderly manner. The separated magnetic cores will be located in the second positioning groove 3360, and the second positioning groove 3360 plays a positioning role for the separated magnetic cores to prevent the magnetic cores from moving at will.

[0084] Furthermore, the second fork rod includes a middle fork rod 3362, a plurality of left fork rods 3363 and a plurality of right fork rods 3364, the left fork rods 3363 are distributed on the left side of the middle fork rod 3362, and the right fork rods 3364 are distributed on the right side of the middle fork rod 3362. The middle fork rod 3362 is the longest, and the tip of the middle fork rod 3362 has two material dividing slopes 3361 for dividing the material to both sides, so the middle fork rod 3362 is first inserted between the two magnetic cores and pushes the two magnetic cores away from each other at the same time. The tip of the left fork rod 3363 has a material dividing slope 3361 for dividing the material to the left side, and the length of the left fork rod 3363 distributed in the left material dividing direction gradually decreases, so the left fork rod 3363 gradually pushes the magnetic cores away to the left. The tip of the right fork rod 3364 has a material dividing slope 3361 for dividing the material to the right, and the length of the right fork rod 3364 distributed in the right material dividing direction gradually decreases, so the right fork rod 3364 gradually pushes the magnetic core to the right. Therefore, the middle fork rod 3362, the left fork rod 3363 and the right fork rod 3364 can push the magnetic core to both sides at the same time, which can more quickly expand the distance between adjacent magnetic cores and improve work efficiency.

[0085] In this embodiment, a transport groove 313 is provided on the transport track 310, a part of the magnetic core is located in the transport groove 313, and another part of the magnetic core extends above the transport groove 313. The transport groove 313 limits the magnetic core, so that the magnetic core only moves along the transport groove 313. In the process of separating the magnetic core by the clamping plate 335 and the fork plate 336, the magnetic core does not move along the insertion direction of the clamping plate 335 and the fork plate 336, so that the fork rod can be inserted between adjacent magnetic cores. At the same time, when the clamping plate 335 and the fork plate 336 are reset, the magnetic core is still in the transport groove 313, so that the magnetic core is separated from the clamping plate 335 and the fork plate 336.

[0086] In this embodiment, the buffer station 311 is provided with a material blocking mechanism 340, and the material blocking mechanism 340 includes a material blocking driver and a material blocking block 341. The material blocking driver is used to drive the material blocking block 341 to move to the transportation path of the magnetic core (the transportation path here refers to the path formed by the magnetic core moving along the conveying direction on the transportation track 310), and the material blocking block 341 blocks the magnetic core from moving to the pad printing station 312, so that the magnetic core is cached in the buffer station 311 to wait for the material clamping plate 335 to divide the material. The material blocking driver can also drive the material blocking block 341 to move away from the transportation path of the magnetic core, and the material blocking block 341 no longer blocks the movement of the magnetic core, and the magnetic core can move from the buffer station 311 to the pad printing station 312.

[0087] Further, the material stopper drive includes a first material stopper cylinder 342 arranged vertically and a second material stopper cylinder 343 arranged horizontally, the second material stopper cylinder 343 is fixed on the push rod of the first material stopper cylinder 342, and the material stopper block 341 is fixed on the push rod of the second material stopper cylinder 343, or the material stopper block 341 is fixed on the material stopper fixing block 344, and the material stopper fixing block 344 is fixed on the push rod of the second material stopper cylinder 343. The first material stopper cylinder 342 can adjust the vertical position of the material stopper block 341, and the second material stopper cylinder 343 can adjust the horizontal position of the material stopper block 341, so that the material stopper block 341 can be moved to the transportation path of the magnetic core or removed from the transportation path of the magnetic core.

[0088] A photoelectric sensor can be fixed on the fixed block 344 to sense the magnetic core on the cache station 311. The photoelectric sensor is connected to the controller. The photoelectric sensor can be set at a position close to the blocking block 341. When the photoelectric sensor senses the magnetic core, it means that there is a magnetic core on the cache station 311. The controller can then control the clamping plate 335 to clamp the magnetic core on the cache station 311, and the clamping plate 335 then moves the magnetic core to the subsequent station.

[0089] The material blocking mechanism 340 may also be connected to a controller, and the controller will control the movement of the material blocking mechanism 340 according to a set control program.

[0090] In this embodiment, the clamping drive 333 and the fork drive 334 can both be cylinders. The driving method of the cylinder is simpler and more efficient, and can make the clamping plate 335 and the fork plate 336 move quickly.

[0091] In this embodiment, the bottom plate driving mechanism includes a bottom plate rail 331 and a bottom plate driver (not shown in the figure), the extension direction of the bottom plate rail 331 is parallel to the conveying direction of the magnetic core on the conveying track 310, the bottom plate 332 is slidably connected to the bottom plate rail 331, and the bottom plate driver can be a cylinder, and the push rod of the cylinder is connected to the bottom plate 332 to drive the bottom plate 332 to slide along the bottom plate rail 331. The bottom plate driver can also be connected to a controller, so that it can coordinate actions with other mechanisms under the drive of the controller.

[0092] The specific working process of the above-mentioned pad printing mechanism 320, material dividing mechanism 330, bottom plate driving mechanism and material blocking mechanism 340 is as follows: the material blocking mechanism 340 first blocks the magnetic core from moving along the transport guide rail 310, and the magnetic core will be cached in the cache station 311; the material blocking driver 333 drives the material blocking plate 335 to move toward the cache station 311 to position the magnetic core of the cache station 311; after positioning the magnetic core of the cache station 311, the material blocking mechanism 340 no longer blocks the magnetic core from moving along the transport guide rail 310, the bottom plate driver drives the bottom plate 332 to move along the conveying direction of the magnetic core, the material blocking plate 335 will drive the magnetic core to move to the pad printing station 312, and the material blocking driver 333 then drives the material blocking plate 335 to reset, so that the material blocking plate 335 is separated from the magnetic core; thereafter, the bottom plate driver drives the bottom plate 332 to move in the direction opposite to the conveying direction of the magnetic core, and the material blocking plate 335 will return to the initial position corresponding to the cache station 311, waiting for the positioning of the next batch of magnetic cores. The above process can be repeated, and the clamping plate 335 will continue to position the magnetic core and continue to transport the magnetic core to the pad printing station 312.

[0093] After the magnetic core moves to the pad printing station 312, the fork material driver 334 drives the fork material plate 336 to move toward the pad printing station 312 to separate the magnetic cores at the pad printing station 312, and the fork material plate 336 will maintain the state of separating the magnetic cores, waiting for the pad printing mechanism 320 to act; after the magnetic cores are separated, the pad printing mechanism 320 pad prints silver paste on the surface of the magnetic cores; after the pad printing mechanism 320 pad prints the silver paste, the clamping material driver 333 drives the clamping material plate 335 to move toward the cache station 311 to position the next batch of magnetic cores on the cache station 311; after the next batch of magnetic cores are positioned, the blocking mechanism 340 no longer blocks the magnetic cores from moving along the transport guide rail 310, and the bottom plate driver drives the bottom plate 332 to move along the conveying direction of the magnetic cores, and the clamping material plate 335 will drive the next batch of magnetic cores The core moves to the pad printing station 312, and at the same time, the fork plate 336 will drive the magnetic core that has been pad-printed with silver paste to move out of the pad printing station 312. A material transfer track can be set to connect with the transportation track 310. The structure of the material transfer track can be the same as that of the transportation track 310. The fork plate 336 moves the magnetic core on the pad printing station 312 to the material transfer track; then, the fork drive 334 drives the fork plate 336 to reset, and the fork plate 336 is separated from the magnetic core; then, the bottom plate drive drives the bottom plate 332 to move in the direction opposite to the core conveying direction, the card plate 335 will return to the initial position corresponding to the cache station 311, and the fork plate 336 will return to the initial position corresponding to the pad printing station 312 to wait for processing the next batch of magnetic cores.

[0094] Hereinafter, the magnetic core drying device 400 will be described in detail.

[0095] An embodiment of the present invention provides a magnetic core drying device, such as Figure 4a-4e As shown, it includes a rotating disk mechanism and a drying mechanism arranged on the machine 100, the rotating disk mechanism includes a driving mechanism and a feeding disk 420, the feeding disk 420 can be placed horizontally, a bracket 410 can be fixed on the machine 100, the driving mechanism can be fixed on the bracket 410, the feeding disk 420 can be located above the driving mechanism and connected to the driving mechanism, the driving mechanism can drive the feeding disk 420 to rotate around its center, the magnetic core is placed on the feeding disk 420, and the feeding disk 420 is rotated and transported. The driving mechanism can be a motor, and the feeding disk 420 is coaxially connected to the output shaft of the motor, thereby driving the feeding disk 420 to rotate.

[0096] The drying mechanism includes a heat preservation cover 430 arranged above the feeding tray 420. The heat preservation cover 430 is close to the upper surface of the feeding tray 420 but is spaced from the upper surface of the feeding tray 420 by a certain distance so as not to affect the rotation of the feeding tray 420. A heating channel is formed between the heat preservation cover 430 and the feeding tray 420. The heating channel is arc-shaped and is concentrically arranged with the feeding tray 420. The heating channel forms a drying inlet 431 at one end of the heat preservation cover 430 and forms a drying outlet 432 at the other end of the heat preservation cover 430. A heater is arranged in the heating channel. The magnetic core can enter the heating channel from the drying inlet 431, and the heater generates heat to dry the magnetic core entering the heating channel. The magnetic core finally moves out of the heating channel from the drying outlet 432.

[0097] Since the feeding tray 420 rotates for feeding, the heating channel is set to be an arc corresponding to the feeding tray 420. Compared with the existing linear feeding, this feeding method can extend the drying time of the magnetic core, thereby effectively improving the drying effect of the magnetic core and ensuring the product quality. At the same time, the heat preservation cover 430 plays a heat preservation role, making the heat in the heating channel not easily dissipated, which helps to improve the drying effect of the magnetic core.

[0098] In this embodiment, a heating box 441 and an air supply duct 442 are further arranged on the machine table 100. A blower and a heating wire are arranged in the heating box 441. Two ends of the air supply duct 442 are respectively communicated with the heating channel and the heating box 441. The heating wire generates heat to heat the air in the heating box 441, and the blower blows the heated air into the air supply duct 442. The heated air enters the heating channel through the air supply duct 442 to increase the temperature in the heating channel and further improve the drying effect of the magnetic core.

[0099] In this embodiment, a mounting bracket 443 is fixed on the machine table 100, and the air supply duct 442 can be fixed to the top of the mounting bracket 443 to keep the air supply duct 442 stable.

[0100] In this embodiment, the heat preservation cover 430 includes a top plate 433, a first arc-shaped plate 434 and a second arc-shaped plate 435. The top plate 433 can be arranged parallel to the feeding tray 420. Both the first arc-shaped plate 434 and the second arc-shaped plate 435 are fixed on the lower surface of the top plate 433. The first arc-shaped plate 434 and the second arc-shaped plate 435 can both be perpendicular to the top plate 433. The first arc-shaped plate 434, the second arc-shaped plate 435 and the feeding tray 420 are concentrically arranged, and the radius of the first arc-shaped plate 434 is greater than the radius of the second arc-shaped plate 435. Thus, the cross-sectional shape of the heat preservation cover 430 will be in the shape of "冂". The top plate 433, the first arc-shaped plate 434, the second arc-shaped plate 435 and the feeding tray 420 enclose to form a heating channel with a consistent width. Therefore, the magnetic core rotating with the feeding tray 420 will not touch the heat preservation cover to ensure the smooth movement of the magnetic core.

[0101] Furthermore, a mounting hole 436 is provided on the top plate 433. The heater is a heating wire. A screw may be provided on the heating wire, and the screw may be fixed in the mounting hole 436, thereby fixing the heating wire to the inner wall of the top plate 433. A plurality of mounting holes 436 may be provided, a plurality of heating wires may be provided, and the heating wires may be distributed along the extension direction of the heating channel to enhance the drying effect.

[0102] In this embodiment, a material receiving station 421 and a material unloading station 422 are provided at a position on the feeding tray 420 that is not covered by the heat preservation cover 430. The material receiving station 421 is close to the drying entrance 431, and the material unloading station 422 is close to the drying exit 432. The material receiving station 421 and the material unloading station 422 are both a position area on the feeding tray 420. The material receiving station 421 is used to receive the magnetic cores, and the magnetic cores are used to be unloaded at the material unloading station 422.

[0103] When the feeding tray 420 rotates, the feeding tray 420 drives the magnetic core, and the magnetic core on the receiving station 421 enters the heating channel through the drying entrance 431, and the magnetic core in the heating channel moves to the unloading station 422 through the drying exit 432. In this regard, this embodiment will provide two loading and unloading methods.

[0104] In one embodiment, loading and unloading are done manually by workers, that is, workers put the magnetic cores to be dried into the receiving station 421. After the magnetic cores are dried, they enter the unloading station 422. The workers then take down the dried magnetic cores, thus forming a semi-automatic magnetic core drying production line.

[0105] In another embodiment, loading and unloading is performed by mechanical automation. Figure 4c-4e As shown, the magnetic core drying device 400 also includes a feeding mechanism 450, a material moving mechanism 460 and a material unloading mechanism 470. The feeding tray 420 is arranged on one side of the feeding mechanism 450, and the feeding mechanism 450 is used to transport the magnetic core to the vicinity of the feeding tray 420. The material moving mechanism 460 is used to move the magnetic core on the feeding mechanism 450 to the material receiving station 421; the material unloading mechanism 470 is arranged at the material unloading station 422, and the material unloading mechanism 470 is used to move the magnetic core at the material unloading station 422 out of the feeding tray 420. The specific working process is as follows:

[0106] The feeding mechanism 450 conveys the magnetic core to the vicinity of the feeding tray 420 and waits for material transfer; the material transfer mechanism 460 moves the magnetic core on the feeding mechanism 450 to the material receiving station 421; the feeding tray 420 drives the magnetic core into the heating channel, and the magnetic core is dried during the movement in the heating channel. The dried magnetic core enters the unloading station 422, and the unloading mechanism 470 moves the magnetic core of the unloading station 422 out of the feeding tray 420, realizing fully automatic magnetic core drying.

[0107] In this embodiment, the material moving mechanism 460 and the feeding tray 420 are respectively arranged on both sides of the feeding mechanism 450. The material moving mechanism 460 includes a material moving cylinder 461 and a material moving plate 462. The push rod of the material moving cylinder 461 is connected to the material moving plate 462. The material moving cylinder 461 drives the push rod to move, thereby driving the material moving plate 462 to move toward the feeding tray 420, so that the magnetic core on the feeding mechanism 450 can be pushed to the material receiving station 421.

[0108] In this embodiment, a plurality of first fork grooves 463 and second fork grooves 464 are provided at one end of the material moving plate 462 close to the feed tray 420. During the material moving process of the material moving plate 462, the magnetic core enters the first fork grooves 463 and the second fork grooves 464 to limit the movement of the magnetic core to both sides, making the material moving more accurate and avoiding position deviation.

[0109] The depth of the first fork groove 463 is greater than the depth of the second fork groove 464, and the first fork groove 463 and the second fork groove 464 are arranged at intervals in the feeding direction of the feeding mechanism 450. In this way, the magnetic cores in the first fork groove 463 and the magnetic cores in the second fork groove 464 will be arranged in two rows in the moving direction of the moving plate 462. Compared with the magnetic cores arranged in one row, this structural setting can increase the distance between two adjacent magnetic cores to prevent the two magnetic cores from sticking together during the drying process.

[0110] In this embodiment, a transition platform 454 is provided on the side of the feeding mechanism 450 close to the feeding tray 420. The side of the transition platform 454 close to the feeding tray 420 is set to an arc shape matching the feeding tray 420. The material moving plate 462 pushes the magnetic core on the feeding mechanism 450 to the transition platform 454 first, and then pushes it to the material receiving station 421. The upper surfaces of the transition platform 454, the feeding tray 420 and the feeding mechanism 450 can be flush to make the movement process of the magnetic core smoother.

[0111] Since the feed tray 420 is a circular structure, it needs to be close to the feed mechanism 450 but cannot contact the feed mechanism 450, and the magnetic cores are pushed to the feed tray 420 in rows. If the magnetic cores on the feed mechanism 450 are directly pushed to the feed tray 420, the magnetic cores will fall from the gap between the feed tray 420 and the feed mechanism 450. Therefore, a transition platform 454 is provided in this embodiment to transfer the magnetic cores from the transition platform 454 to the feed tray 420, so as to prevent the magnetic cores from falling.

[0112] In this embodiment, the feeding mechanism 450 includes a feeding guide rail 452, a feeding driver 453 and a feeding block (not shown in the figure) for placing the magnetic core. The feeding guide rail 452 can be fixed on the feeding base 451, and the feeding block is slidably connected to the feeding guide rail 452. The feeding driver 453 can be a cylinder, which drives the feeding block to slide along the feeding guide rail 452 so that the feeding block transports the magnetic core.

[0113] In this embodiment, the unloading mechanism 470 includes an unloading baffle, one end of which is fixed to the side of the drying outlet 432 close to the center of the feeding tray 420, and the other end of which gradually extends in a direction away from the center of the feeding tray 420. When the magnetic core moves out of the drying outlet 432, it will be blocked by the unloading baffle, so that the magnetic core gradually moves out of the feeding tray 420. A receiving device can be provided on the outer side of the feeding tray 420 close to the drying outlet 432 to receive the magnetic core moved out by the unloading plate.

[0114] Hereinafter, the magnetic core blanking device 500 will be described in detail.

[0115] An embodiment of the present invention provides a magnetic core blanking device 500, such as Figure 5 As shown, the magnetic core unloading device 500 includes a material unloading plate 510 and a receiving mechanism. The material unloading plate 510 has a material unloading trough 520. The material unloading trough 520 is tilted, and a material inlet is provided at one end with a higher height, and a material outlet is provided at one end with a lower height. The magnetic cores dried by the magnetic core drying device 400 enter the material unloading trough 520 from the material inlet. Under the action of their own gravity, the magnetic cores will slide along the material unloading trough 520 and finally slide out from the material outlet. The receiving mechanism can be arranged below the material outlet to receive the fallen magnetic cores and collect them.

[0116] In this embodiment, side plates 511 are provided on both sides of the blanking plate 510 in the blanking direction, so that the magnetic core will not fall from the side of the blanking plate 510, thereby avoiding material loss.

[0117] In this embodiment, a blocking mechanism is provided at the blanking outlet, and the blocking mechanism is used to open or close the blanking outlet. Since the dried magnetic core is relatively fragile, if the blanking speed is too fast, it is easy to cause damage to the magnetic core. In this embodiment, a blocking mechanism is provided, so that the magnetic core sliding in the blanking trough 520 can be cached in the blanking outlet. When the blocking mechanism opens the blanking outlet, the material can fall into the receiving structure.

[0118] Furthermore, the blocking mechanism includes a blocking cylinder 531 and a blocking plate 532. The blocking plate 532 is connected to the push rod of the blocking cylinder 531. The push rod drives the blocking plate 532 to move closer to or away from the blanking plate 510.
