[0002] At present, when grooving the end face of a magnetic core, usually a four-station grinding machine is first used to grind the magnetic core into a corresponding shape, and then a through-feed chamfering machine is used to groove the end face of the magnetic core. During the process of grooving the end face of the magnetic core by using the through-feed chamfering machine, the magnetic core is not fixed, and the stability is poor. Therefore, during the processing, it is easy to generate corner dropping and damage the product. Moreover, the size consistency of the grooves machined is uneven, and the product quality is poor. In addition, it is necessary to rely on manual feeding and discharging continuously, the degree of automation is low, the manual labor intensity is large, the production efficiency is low, and the processing cost is high.

[0035] Combine the following Figures 1 to 7 , describing an embodiment of the utility model.

[0036] According to an embodiment of the present invention, there is provided a device for grooving the end face of a magnetic core, comprising: a feeding mechanism 1, a conveying mechanism 2 and a grooving mechanism 3. The conveying mechanism 2 is connected to the tail of the feeding mechanism 1 and is adapted to receive the magnetic core transmitted from the feeding mechanism 1 and convey the magnetic core in a first direction; the grooving mechanism 3 is connected to the tail end of the conveying mechanism 2 along the first direction. The grooving mechanism 3 includes a support table 310, a clamping assembly 320, a grinding assembly 330 and a discharging assembly 340. The clamping assembly 320 is movably connected to the support table 310. The clamping assembly 320 has a first working position corresponding to the conveying mechanism 2 and a second working position corresponding to the discharging assembly 340. The clamping assembly 320 can selectively clamp the magnetic core; the grinding assembly 330 is movably arranged on the support table 310. The grinding assembly 330 is adapted to groove the end face of the magnetic core when the clamping assembly 320 clamps the magnetic core; the discharging assembly 340 is arranged on the support table 310. The discharging assembly 340 is adapted to receive and output the magnetic core released by the clamping assembly 320. Wherein, the first direction refers to Figure 1 the "first direction" indicated by the arrow in, that is, the direction from the feeding mechanism 1 to the grooving mechanism 3.

[0037] Applying the device for grooving the end face of the magnetic core of this embodiment, by sequentially connecting the feeding mechanism 1, the conveying mechanism 2 and the grooving mechanism 3, the magnetic core automatically enters the grooving mechanism 3 for grooving processing after being fed by the feeding mechanism 1 and conveyed by the conveying mechanism 2. And, by setting the clamping assembly 320 in the grooving mechanism 3 to have a first working position corresponding to the conveying mechanism 2, the magnetic core can be directly conveyed by the conveying mechanism 2 to the clamping assembly 320 and clamped and fixed by the clamping assembly 320, realizing automatic and accurate positioning of the magnetic core. Then, the end face of the magnetic core fixed in the clamping assembly 320 is grooved by the grinding assembly 330, which can avoid the shaking of the magnetic core during the grooving process, thereby improving the grooving accuracy, improving the product quality. And by setting the clamping assembly 320 to also have a second working position corresponding to the discharging assembly 340, the clamping assembly 320 can carry the grooved magnetic core to move to the second working position and release the magnetic core at the second working position, so that the magnetic core falls onto the discharging assembly 340, and then the magnetic core is conveyed out by the discharging assembly 340, that is, automatic discharging is realized. The whole processing process is completed at one time, without manual handling of the magnetic core in the middle, with high automation degree, high production efficiency, high grooving dimension accuracy, low manual labor intensity, high safety, and is beneficial to improving the product quality and production efficiency.

[0038] Optionally, the magnetic core is a permanent ferrite magnetic core. Further, the magnetic core can be a special-shaped ultra-thick permanent ferrite magnetic core. Specifically, by setting the shape of the fixture in the clamping assembly 320, the shape of the magnetic core can be adapted to realize the clamping and fixing of the magnetic core.

[0039] In one embodiment, the feeding mechanism 1 includes: a feeding machine main body 110, a transmission unit 120 and a pushing unit 130. The feeding machine main body 110 includes a main body portion 111 and a support frame 112. The upper surface of the main body portion 111 is inclined. The support frame 112 is disposed above the main body portion 111 and corresponds to the top end of the main body portion 111. The transmission unit 120 is disposed on the upper surface of the main body portion 111. The tail of the transmission unit 120 is higher than its head. The transmission unit 120 is adapted to transmit magnetic cores in the direction from its head to its tail. The pushing unit 130 is disposed on the support frame 112. The pushing unit 130 is located above the transmission unit 120 and corresponds to the tail of the transmission unit 120. The pushing unit 130 is adapted to push the magnetic cores on the transmission unit 120 onto the conveying mechanism 2 in a first direction. Wherein, the upper surface refers to the surface in the direction of "up" indicated by the arrow in Figure 1 ; the head and tail of the transmission unit 120 refer to the head and tail along the transmission direction of the transmission unit 120; the top end of the main body portion 111 corresponds to the tail of the transmission unit 120. By arranging the upper surface of the main body portion 111 of the feeding machine main body 110 to be inclined, the tail of the transmission unit 120 disposed on the upper surface of the main body portion 111 is higher than its head. Then, during the process of the transmission unit 120 transmitting magnetic cores, the magnetic cores are transmitted from a lower position to a higher position. The staff only needs to place the magnetic cores at the lower position on the transmission unit 120 and monitor the operation status of the equipment, which saves time and effort. And by arranging the support frame 112 to be connected to the top end of the main body portion 111, the pushing unit 130 disposed on the support frame 112 is located directly above the tail of the transmission unit 120. The pushing unit 130 can push the magnetic cores on the tail of the transmission unit 120 onto the conveying mechanism 2 in a first direction, thereby realizing the transfer of the magnetic cores from the feeding mechanism 1 to the conveying mechanism 2 without manual operation and with a high degree of automation.

[0040] In one embodiment, the transmission direction of the transmission unit 120 is Figure 1 the "feeding direction" indicated by the arrow in, which is perpendicular to the first direction. Then, the pushing direction of the pushing unit 130 on the magnetic cores is perpendicular to the transmission direction of the transmission unit 120, which is beneficial to saving space.

[0041] In one embodiment, the transmission unit 120 includes a transmission chain and a first driving part 122. Multiple rows of support grooves 121 are provided on the surface of the transmission chain. The multiple rows of support grooves 121 are arranged at intervals along the transmission direction of the transmission chain. Each support groove 121 is a through groove extending in the first direction; the first driving part 122 is connected to the transmission chain to drive the transmission chain to move. Among them, the transmission chain is a chain structure that can rotate cyclically on the upper surface of the loader main body 110. The first driving part 122 is connected to the sprocket of the chain structure, and the chain is driven to move cyclically by driving the sprocket to rotate, so as to continuously transport the magnetic core. The moving direction of the upward side of the chain structure is the transmission direction of the transmission unit 120, that is, Figure 1 the "loading direction" indicated by the arrow in Figure 1 ; the surface of the transmission chain refers to the surface of the chain structure facing away from the sprocket. By providing multiple rows of support grooves 121 distributed at intervals on the surface of the transmission chain, it is ensured that during the cyclic movement of the transmission chain, there are always support grooves 121 on the upper surface of the loader main body 110 to support the magnetic core, so as to realize the uninterrupted transmission of the magnetic core. And by setting the support groove 121 as a through groove extending in the first direction, the pushing direction of the pushing unit 130 is the same as the extending direction of the support groove 121, and the pushing unit 130 can directly push the magnetic core out of the support groove 121 along the extending direction of the support groove 121, which is convenient for realizing the transfer of the magnetic core from the transmission unit 120 to the conveying mechanism 2, with high automation and beneficial to improving the processing efficiency.

[0042] It should be noted that the extending direction of the support groove 121 refers to the length direction of the support groove, that is, the direction perpendicular to the groove depth; the support groove 121 is provided on the surface of the transmission chain. The support groove 121 is used to support the magnetic core. The magnetic core is placed in the support groove 121 and can slide along the extending direction of the support groove 121. Both ends of the support groove 121 along its extending direction are open ends. Then, the magnetic core located in the support groove 121 can be directly output from the support groove 121 under the push of the pushing unit 130 without manual handling and transfer, with high automation; the support groove 121 is provided on the entire circle of the surface of the transmission chain to realize the continuous feeding and conveying of the magnetic core. Preferably, the multiple rows of support grooves 121 are equally spaced on the surface of the transmission chain, with good uniformity.

[0043] In one embodiment, the support groove 121 includes two support plates arranged at intervals in the groove width direction. A support groove 121 is formed between the two support plates. The structure is simple and the cost is low. Among them, the groove width direction refers to the direction perpendicular to the extending direction of the support groove 121 and perpendicular to the groove depth, and is parallel to the transmission direction of the transmission chain. Preferably, the included angle between the two support plates is adjustable, so as to adjust the opening angle of the support groove according to the special shape of the magnetic core, so as to realize the stable support of the magnetic core, ensure the stability of the magnetic core transmission process, and make the magnetic core arrangement and positioning orderly and the conveying smooth.

[0044] In one embodiment, a first protective cover 123 is provided on the loader main body 110. The first protective cover 123 covers the outside of the first driving part 122 to protect the first driving part.

[0045] In one embodiment, the loading mechanism 1 further includes a loader control box 140. The loader control box 140 is arranged on the loader main body 110. The first driving part 122 is a servo motor, and the rotation speed of the first driving part 122 is controlled by the loader control box 140, so as to control the conveying speed of the conveying chain. After all the magnetic cores on a support groove 121 at the top of the main body part 111 are pushed onto the conveying mechanism 2, then control the conveying chain to move, so as to move the next support groove 121 to the top of the main body part 111.

[0046] In one embodiment, the pushing unit 130 includes a pushing part 131 and a second driving part 132. The pushing part 131 is movably arranged on the support frame 112. The pushing part 131 can selectively move in the first direction or in the opposite direction of the first direction. The pushing part 131 has a pushing state of extending downward relative to the support frame 112 and a retracting state of retracting upward. When the pushing part 131 is in the pushing state, it is suitable for pushing the magnetic core to move in the first direction. When the pushing part 131 is in the retracting state, it is suitable for being spaced apart from the magnetic core in the vertical direction. The second driving part 132 is suitable for driving the pushing part 131 to move relative to the support frame 112. Among them, "downward" refers to the direction of "down" pointed by the arrow in Figure 1 ; "upward" refers to the direction of "up" pointed by the arrow in Figure 1 . By setting that the pushing part 131 can move relative to the support frame 112 in the first direction or the opposite direction of the first direction, the reciprocating movement of the pushing part 131 moving forward or backward in the first direction is realized. And the pushing part 131 extends downward relative to the support frame 112 during the process of moving forward in the first direction, so as to realize the contact between the pushing part 131 and the magnetic core, which is convenient for the pushing part 131 to push the magnetic core to move in the first direction. While the pushing part 131 retracts upward relative to the support frame 112 during the retracting process, ensuring that the pushing part 131 does not contact the magnetic core during the process of moving in the opposite direction of the first direction to the end of the support frame 112 away from the conveying mechanism 2, so as to realize the smooth progress of the reciprocating movement process of the pushing unit 130.

[0047] Specifically, the pushing unit 130 is located directly above the end of the transmission unit 120. When a certain support groove 121 on the transmission unit 120 moves to the top of the main body portion 111, this support groove 121 is located directly below the pushing unit 130. When the pushing portion 131 extends downward relative to the support frame 112, at least a part of the pushing portion 131 is lower than the upper surface of the magnetic core supported in this support groove 121. At this time, when the pushing portion 131 moves in the first direction, it can push the magnetic core to move in the first direction, that is, the pushing portion 131 moves from a position away from the conveying mechanism 2 towards a position close to the conveying mechanism 2, so as to push the magnetic core from the support groove 121 of the transmission unit 120 onto the conveying mechanism 2 through the pushing portion 131; when the pushing portion 131 retracts upward relative to the support frame 112, the pushing portion 131 will not interfere with the magnetic core. At this time, the pushing portion 131 moves in the opposite direction of the first direction to move to one end of the support frame 112 away from the conveying mechanism 2 to prepare for the next push of the magnetic core in the first direction.

[0048] In one embodiment, the pushing portion 131 includes a connecting portion and a movable portion. The connecting portion is movably connected to the support frame 112 in the first direction, and the movable portion is connected to the connecting portion. The movable portion can telescopically extend and retract relative to the connecting portion. When the movable portion extends downward relative to the connecting portion, the pushing portion 131 is in a pushing state. When the movable portion retracts upward relative to the connecting portion, the pushing portion 131 is in a retracted state. Preferably, a push rod is fixedly connected to the end of the movable portion away from the connecting portion, and the push rod corresponds exactly to the support groove 121 at the top of the main body portion 111, so as to be able to just extend into the support groove 121 to push the magnetic core when the pushing portion 131 is in the pushing state.

[0049] In one embodiment, the pushing portion 131 is a cylinder, and the telescopic rod of the cylinder can telescopically extend and retract in the up and down direction. When the telescopic rod of the cylinder extends downward, the pushing portion 131 is in a pushing state; when the telescopic rod of the cylinder retracts upward, the pushing portion 131 is in a retracted state.

[0050] In one embodiment, a sprocket chain structure is provided on the support frame 112, including a chain 133 and two sprockets 134 supporting the chain 133. The pushing portion 131 is fixedly connected to the chain 133. The two sprockets 134 are arranged at intervals in the first direction. The sprockets 134 are driven to rotate by a second driving portion 132, so as to drive the chain 133 to move through the rotation of the sprockets 134, and thus drive the pushing portion 131 to move. Specifically, by driving the chain 133 to rotate clockwise through the sprockets 134, the pushing portion 131 can be driven to move forward in the first direction; by driving the chain 133 to rotate counterclockwise through the sprockets 134, the pushing portion 131 can be driven to move in the opposite direction of the first direction, that is, the pushing portion 131 retreats.

[0051] In one embodiment, the number of the pushing parts 131 is two. The two pushing parts 131 are arranged side by side and the moving directions of the two pushing parts 131 are opposite. It should be noted that the side-by-side arrangement means arranging side by side in a direction perpendicular to the first direction in the horizontal plane; the push rods on the two pushing parts 131 are exactly corresponding to the support grooves 121 at the top end of the main body part 111, that is, both of the two pushing parts 131 push the magnetic core supported in the support grooves 121. By setting the moving directions of the two side-by-side pushing parts 131 to be opposite, when one pushing part 131 pushes the magnetic core forward, the other pushing part 131 moves backward to return to the starting position, and cycles in turn, so as to ensure that there is always one pushing part 131 pushing the magnetic core in the support groove 121, thereby realizing the alternating work of the two pushing parts 131, realizing the uninterrupted feeding of the magnetic core, and improving the work efficiency. Herein, forward refers to along the first direction, and backward refers to along the opposite direction of the first direction; the starting position refers to the end of the support frame 112 far from the conveying mechanism 2.

[0052] In one embodiment, the number of the second driving parts 132 is one. One second driving part 132 drives the two pushing parts 131 to move simultaneously, which is beneficial to saving space and reducing costs. Specifically, two sets of sprocket and chain structures are arranged side by side on the support frame 112. Each set of sprocket and chain structure includes a chain 133 and two sprockets 134 supporting the chain 133. The two sprockets 134 are arranged at intervals along the first direction. A pushing part 131 is fixedly connected to each chain 133. The rotation directions of the sprockets in the two sets of sprockets and chains are opposite, so that one second driving part 132 can drive one of the two pushing parts 131 to move forward and the other to move backward simultaneously.

[0053] In addition, in other embodiments, the number of the second driving parts 132 can also be two. Each second driving part 132 drives one pushing part 131 to move respectively, which is convenient for operation.

[0054] In one embodiment, the conveying mechanism 2 includes: a first conveyor belt 201 and a third driving part 202. One end of the first conveyor belt 201 is connected to the tail of the transmission unit 120, and the other end of the first conveyor belt 201 is connected to the support table 310 and corresponds to the first station of the clamping assembly 320; the third driving part 202 is adapted to drive the first conveyor belt 201 to move. By setting the first conveyor belt 201 to be connected between the transmission unit 120 and the support table 310, the first conveyor belt 201 moves along the first direction under the drive of the third driving part 202, so as to realize conveying the magnetic core on the transmission unit 120 to the support table 310, that is, realizing the automatic transfer of the magnetic core on the feeding mechanism 1 to the grooving mechanism 3. The automation degree is high, manual handling is not required, labor is saved, and the work efficiency is improved.

[0055] In one embodiment, the third driving part 202 is a servo motor, which has a high degree of automation and high precision.

[0056] In one embodiment, the conveying mechanism 2 further includes: a limiting plate 203. The limiting plate 203 extends along the first direction. The limiting plate 203 is arranged at an interval from the first conveyor belt 201. The number of the limiting plates 203 is two. The two limiting plates 203 are arranged at intervals along the width direction of the first conveyor belt 201. A limiting channel is formed between the two limiting plates 203 to limit the magnetic core on the first conveyor belt 201 along the width direction of the first conveyor belt 201. Wherein, the width direction of the first conveyor belt 201 refers to the direction perpendicular to the conveying direction of the first conveyor belt 201 in the horizontal plane. Since the limiting plate 203 is arranged at an interval from the first conveyor belt 201, the limiting plate 203 will not interfere with the movement of the first conveyor belt 201. By setting the extending direction of the limiting plate 203 to be the same as the conveying direction of the first conveyor belt 201 and arranging the two limiting plates 203 at intervals along the width direction of the first conveyor belt 201, the extending direction of the limiting channel formed between the two limiting plates 203 is the same as the conveying direction of the first conveyor belt 201. Thus, it is ensured that during the process of the first conveyor belt 201 conveying the magnetic core, the magnetic core is always located in the limiting channel, preventing the magnetic core from falling off the first conveyor belt 201, improving the reliability of the conveying process, and ensuring the smooth progress of the conveying process.

[0057] In one embodiment, the conveying mechanism 2 further includes: a bracket 204. The bracket 204 extends along the first direction. One end of the bracket 204 is connected to the tail end of the transmission unit 120 on the feeding mechanism 1 and the other end is fixed on the support table 310 of the grooving mechanism 3. The first conveyor belt 201, the third driving part 202 and the limiting plate 203 are arranged on the bracket 204. The limiting plate 203 is fixed on the bracket 204. The bracket 204 is used to support the first conveyor belt 201, the third driving part 202 and the limiting plate 203.

[0058] In one embodiment, a first adjustment unit 361 corresponding to the bracket 204 of the conveying mechanism 2 is arranged on the support table 310. The first adjustment unit 361 is used to adjust the position of the bracket 204 in the up and down direction, so as to ensure that the first conveyor belt 201 can be directly opposite to the clamping assembly 320.

[0059] In one embodiment, a connecting groove 4 is arranged between the feeding mechanism 1 and the conveying mechanism 2. One end of the connecting groove 4 is connected to the tail of the feeding mechanism 1 and the other end corresponds to the first conveyor belt 201 of the conveying mechanism 2. A support groove 121 at the tail of the feeding mechanism 1 corresponds to the connecting groove 4. The magnetic core in the support groove 121 is transferred to the first conveyor belt 201 through the connecting groove 4, thereby realizing the transfer of the magnetic core from the feeding mechanism 1 to the conveying mechanism 2, ensuring the reliability of the magnetic core transfer process, and preventing the magnetic core from falling during the transfer process.

[0060] In one embodiment, the clamping assembly 320 includes: a fixture body 321 and a clamping portion 322. The fixture body 321 is movably arranged on the support table 310, and a support portion is configured on the fixture body 321; the clamping portion 322 is telescopically connected to the fixture body 321 and is arranged opposite to the support portion. A clamping space is formed between the clamping portion 322 and the support portion to accommodate the magnetic core. When the clamping portion 322 is suitable for extending relative to the fixture body 321, it presses the magnetic core on the fixture body 321, and when it retracts relative to the fixture body 321, it releases the magnetic core. By configuring a support portion and a corresponding clamping portion 322 on the fixture body 321, and the clamping portion 322 is telescopically connected to the fixture body 321, the clamping portion 322 can move relative to the support portion to approach or move away from the support portion, so as to change the size of the clamping space between the clamping portion 322 and the support portion, and thus clamp or release the magnetic core by the extension or retraction of the clamping portion 322. It has good flexibility and high reliability. And by setting the fixture body 321 to be movable relative to the support table 310, it is convenient to realize the movement of the clamping assembly 320 between the first station and the second station, with a high degree of automation and is beneficial to improving work efficiency. Preferably, the moving direction of the fixture body 321 relative to the support table 310 is perpendicular to the conveying direction of the conveying mechanism 2. The moving direction of the fixture body 321 on the support table 310 is as Figure 5 indicated by the arrow of the "second direction" in the figure. The second direction is located in the horizontal plane and is perpendicular to the first direction.

[0061] Wherein, the number of the clamping portions 322 is at least one.

[0062] In one embodiment, the number of clamping portions 322 is plural. The plural clamping portions 322 are arranged in sequence along the direction in which the fixture body 321 is movable relative to the support table 310, and the plural clamping portions 322 are arranged in sequence along the second direction. Then, the arrangement direction of the plural clamping portions 322 is perpendicular to the conveying direction of the conveying mechanism 2. Each clamping portion 322 can clamp one magnetic core. By setting the number of clamping portions 322 to be plural, the clamping assembly 320 can clamp plural magnetic cores at one time, so that it is convenient for the grinding assembly 330 to perform grooving processing on the plural magnetic cores simultaneously, further improving the processing efficiency. Specifically, along the second direction, the plural clamping portions 322 are, in sequence, a first clamping portion, a second clamping portion,.... Initially, each clamping portion 322 is in a retracted state. The first clamping portion on the clamping assembly 320 corresponds to the first conveyor belt 201 of the conveying mechanism 2. After the conveying mechanism 2 feeds a magnetic core into the clamping assembly 320, the first clamping portion switches to an extended state to clamp the magnetic core. Subsequently, the fixture body 321 moves along the second direction to align the next clamping portion 322 with the conveying mechanism 2, so as to feed the second magnetic core into the clamping assembly 320. The second clamping portion switches to an extended state to clamp the magnetic core, and so on. The conveying mechanism 2 feeds the magnetic cores equal in number to the clamping portions 322 into the clamping assembly one by one and fixes them one by one with the plural clamping portions 322. Preferably, the number of clamping portions 322 is eight, and the clamping assembly 320 can clamp eight magnetic cores at one time.

[0063] In addition, in other embodiments, the number of clamping portions 322 can also be one, with a simple structure and convenient for processing.

[0064] In one embodiment, the clamping portion 322 is a cylinder. When the telescopic rod of the cylinder extends, it can press the magnetic core to fix the magnetic core, and when the telescopic rod retracts, it can... the magnetic core.

[0065] In one embodiment, the grooving mechanism 3 further includes: a guiding assembly. The guiding assembly includes a guiding member 371. The guiding member 371 is fixedly connected to the support table 310 and extends along the second direction. The fixture body 321 is movably connected to the guiding member 371. The guiding member 371 provides guidance for the movement of the fixture body 321 on the support table 310, ensuring the smoothness of the movement process of the fixture body 321 on the support table 310, thereby ensuring the processing accuracy. It should be noted that the guiding member 371 is arranged side by side with the discharging assembly 340 to facilitate unloading the magnetic cores on the clamping assembly 320 onto the discharging assembly 340.

[0066] In one embodiment, the guide member 371 is a guide rail. A guide groove is formed on the lower side of the fixture body 321. The guide rail is inserted into the guide groove, thereby realizing the sliding fit between the fixture body 321 and the guide rail. The guide rail has a simple structure and good guiding performance. Preferably, the number of guide rails is two, and the two guide rails are arranged in parallel along the first direction, further improving the smoothness of the guiding process. It can be understood that as an alternative embodiment, the guide member 371 can also be a sliding groove, and a slider is arranged on the lower side of the fixture body 321. The slider is slidably engaged with the sliding groove, and the guiding function of the guide member 371 on the fixture body 321 can also be realized.

[0067] In one embodiment, the guiding assembly further includes: a fixture transmission assembly and a fourth driving part 372. The clamping assembly 320 is fixedly connected to the fixture transmission assembly, and the fixture transmission assembly is located below the guide member 371. The fourth driving part 372 is used to drive the fixture transmission assembly to move along the second direction, thereby driving the clamping assembly 320 to move along the second direction, with high automation and high working efficiency. Preferably, the fixture transmission assembly is a gear-rack structure. The rack extends along the second direction, and the fourth driving part 372 drives the gear to rotate, and the gear drives the rack to move.

[0068] In one embodiment, the grinding assembly 330 includes: a main shaft 331, a grinding wheel 332 and a grinding wheel driving part 333. The main shaft 331 is movably connected to the support table 310; the grinding wheel 332 is rotatably connected to the lower end of the main shaft 331. The grinding wheel 332 is adapted to move relative to the support table 310 driven by the main shaft 331; the grinding wheel driving part 333 is arranged on the main shaft 331 and connected to the grinding wheel 332. The grinding wheel driving part 333 is adapted to drive the grinding wheel 332 to rotate. It should be noted that the lower end refers to one end in the direction of "down" indicated by the arrow in Figure 1 ; the main shaft 331 can move up and down relative to the support table 310 and can move left and right relative to the support table 310. Among them, the up and down movement refers to the movement in the "up and down" direction indicated by the arrow in Figure 1 ; the left and right movement refers to the movement in the positive or negative direction of the "first direction" indicated by the arrow in Figure 1 . By setting that the main shaft 331 can move relative to the support table 310, it is convenient to adjust the position of the grinding wheel 332 connected to the lower end of the main shaft 331 by adjusting the position of the main shaft 331 on the support table 310, thereby adjusting the grooving position and grooving depth of the grinding wheel 332 on the surface of the magnetic core, with good flexibility; the grinding wheel driving part 333 is used to drive the grinding wheel 332 to rotate, thereby realizing grooving of the grinding wheel 332 on the surface of the magnetic core, with high automation and simple operation.

[0069] It should be noted that during the process of grooving the end face of the magnetic core, the main shaft 331 remains stationary. By moving the clamping assembly 320 along the second direction, multiple magnetic cores can be sequentially fed into the position corresponding to the grinding wheel 332, thereby realizing the sequential grooving of the multiple magnetic cores on the clamping assembly 320.

[0070] In one embodiment, the number of main shafts 331 is two. A grinding wheel 332 is connected to the lower end of each main shaft 331, and a grinding wheel driving part 333 is arranged on each main shaft 331. Each grinding wheel driving part 333 is used to drive a corresponding grinding wheel 332 to rotate.

[0071] In one embodiment, the grinding wheel driving part 333 is arranged at the upper end of the main shaft 331.

[0072] In one embodiment, the grinding wheel driving part 333 is a motor. A pulley is installed at the upper end of the main shaft 331 and is driven by two frequency conversion motors, thereby driving the grinding wheel 332 to rotate.

[0073] In one embodiment, a connecting frame 311 is constructed on the support table 310. The connecting frame 311 is fixedly connected to the upper end face of the main body part of the support table 310, and the main shaft 331 is movably connected to the connecting frame 311. The connecting frame 311 is in a gate shape and allows the clamping assembly 320 to pass through without interfering with the movement of the clamping assembly 320 between the first station and the second station.

[0074] In one embodiment, a second protective cover 334 is arranged on the support table 310 to provide safety protection and waterproofing for the grinding wheel 332 and the rotating part of the main shaft.

[0075] In one embodiment, a second adjustment unit 362 is arranged on the connecting frame 311 to adjust the distance between the main shaft 331 and the fixture body 321 in the first direction, thereby realizing the adjustment of the groove depth of the groove on the end face of the magnetic core. The structure is simple and the adjustment is convenient. Preferably, the second adjustment unit 362 is an adjusting nut.

[0076] In one embodiment, the discharging assembly 340 includes: a second conveyor belt 341 and a discharging driving part 342. The second conveyor belt 341 is arranged on the support table 310 and is adapted to move along a second direction. The second conveyor belt 341 corresponds to the second station of the clamping assembly 320 and is adapted to receive the magnetic core released by the clamping assembly 320 and convey the magnetic core along the second direction. The discharging driving part 342 is arranged on the support table 310 and is adapted to drive the second conveyor belt 341 to move. Wherein, the fact that the second conveyor belt 341 is adapted to move along the second direction means that under the driving action of the discharging driving part 342, the upper surface of the second conveyor belt 341 moves along the second direction. By arranging the second conveyor belt 341 to correspond to the second station of the clamping assembly 320, when the clamping assembly 320 moves to the second station and releases the magnetic core, the magnetic core disengaged from the clamping assembly 320 can directly fall onto the second conveyor belt 341, and the second conveyor belt 341 can move along the second direction. The discharging driving part 342 drives the second conveyor belt 341 to move, so that the second conveyor belt 341 drives the magnetic core to move along the second direction, realizing automatic discharging of the magnetic core, avoiding magnetic core accumulation, ensuring the smoothness of the processing process, and having a high degree of automation.

[0077] In one embodiment, the grooving mechanism 3 further includes a kicking unit 350 arranged on the support table 310. The kicking unit 350 corresponds to the second station of the clamping assembly 320 and is located on the side of the clamping assembly 320 away from the discharging assembly 340. The kicking unit 350 includes: a fixing part and a telescopic part. The fixing part is fixedly connected to the support table 310; the telescopic part is telescopically connected to the fixing part. The telescopic part has an extended state of extending relative to the fixing part and a retracted state of retracting relative to the fixing part. When the telescopic part is in the extended state, it is adapted to kick out the magnetic core on the clamping assembly 320. It should be noted that when the clamping assembly 320 is at the second station, when the telescopic part of the kicking unit 350 extends relative to the fixing part, the telescopic part can extend into the clamping space between the support part and the clamping part 322 on the fixture body 321, so as to kick out the magnetic core in the clamping assembly 320. By arranging the kicking unit 350 corresponding to the second station of the clamping assembly 320 on the support table 310, when the clamping assembly 320 moves to the second station and releases the magnetic core, by switching the telescopic part of the kicking unit 350 to the extended state, the magnetic core in the clamping assembly 320 can be kicked out, so as to ensure that the magnetic core can be smoothly transferred from the clamping assembly 320 to the second conveyor belt 341 of the discharging assembly 340, realizing smooth discharging of the magnetic core.

[0078] Specifically, by moving the clamping assembly 320 along the second direction, the kicking unit 350 kicks out more magnetic cores in sequence.

[0079] In one embodiment, the discharging assembly 340 further includes a protective plate disposed on both sides in the width direction of the second conveyor belt 341 to limit the magnetic cores on the second conveyor belt 341, prevent the magnetic cores kicked out by the kicker unit 350 from falling outside the second conveyor belt 341, and avoid the magnetic cores on the second conveyor belt 341 from falling during transportation, thereby ensuring the smooth progress of the discharging process.

[0080] In one embodiment, the discharging assembly 340 further includes a transfer groove 343 corresponding to the second station of the clamping assembly 320. The transfer groove 343 is located between the second station of the clamping assembly 320 and the second conveyor belt 341. The transfer groove 343 is inclined. The higher end of the transfer groove 343 corresponds to the position of the magnetic core on the clamping assembly 320 and is slightly lower than the magnetic core. The lower end of the transfer groove 343 corresponds to the upper side of the second conveyor belt 341 and is slightly higher than the second conveyor belt 341. Thus, the magnetic core kicked out from the clamping assembly 320 by the kicker unit 350 can slide down along the transfer groove 343 onto the second conveyor belt 341. The transfer groove 343 provides guidance and support for the transfer of the magnetic core, which is beneficial to improving the smoothness of the transfer process.

[0081] In one embodiment, the grooving mechanism 3 further includes: a grooving machine control box 380 disposed on the support table 310. The grinding wheel driving part 333, the discharging driving part 342, and the fourth driving part 372 are all controlled by the grooving machine control box 380, with high automation and high precision. The loading machine control box 140 is linked with the grooving machine control box 380. The loading machine control box 140 can adjust the working condition of the loading mechanism 1 according to the working condition of the grooving machine control box 380. Specifically, when the grooving machine control box 380 controls the grinding wheel driving part 333 to work, it means that the magnetic core clamped in the clamping assembly 320 is being grooved. At this time, the loading machine control box 140 can control the loading mechanism 1 to suspend loading to avoid material accumulation.

[0082] In one embodiment, the magnetic core end face grooving device further includes a detection unit electrically connected to the loading machine control box 140. The detection unit includes a first detection unit and a second detection unit. The first detection unit is used to detect the material shortage situation on a support groove 121 corresponding to the pushing unit 130 on the transmission unit 120. Thus, the loading machine control box 140 controls the first driving part 122 to rotate according to the material shortage situation, thereby controlling the transmission chain to load materials. The second detection unit can be used to detect the material shortage situation on the first conveyor belt 201 of the conveying mechanism 2. Thus, the loading machine control box 140 controls the second driving part 132 to move according to the material shortage situation, thereby realizing alternating and uninterrupted loading. Preferably, the detection unit is an infrared detection structure.

[0083] In this embodiment, the processing process of the magnetic core by the magnetic core end face grooving device is as follows:

[0084] Place the magnetic core on the transmission unit 120. By alternately operating the two pushing parts 131 of the pushing unit 130, the magnetic core is continuously pushed onto the conveying mechanism 2. The magnetic core is fed into the clamping assembly 320 one by one through the conveying mechanism 2 (infinitely variable speed) for automatic and precise positioning. The guiding assembly drives the clamping assembly 320 to move horizontally, and cooperates with the clamping part 322 to fix multiple magnetic cores one by one. Then, the grinding wheels 332 connected to the lower ends of the two main shafts 331 of the grinding assembly 330 perform synchronous grooving processing on the two end faces of the magnetic core. After the grooving processing of the magnetic core is completed, the clamping part 322 releases the magnetic core, and then the magnetic core is kicked out of the clamping assembly 320 one by one by the kicking unit 350. The kicked magnetic core falls onto the second conveyor belt 341 of the discharging assembly 340 for automatic discharging.

[0085] Among them, the first driving part 122, the second driving part 132, the third driving part 202, the fourth driving part 372 and the discharging driving part are all servo motors, and the clamping part 322 and the kicking unit 350 are cylinders. The POC system is used to control the actions of the above servo motors and cylinders, realizing continuous automatic alternate feeding, automatic feeding for precise positioning and clamping, synchronous grooving processing of two end faces and automatic discharging.
