Description

Technical Field

[0001] The invention relates to the technical field of magnetic core separation, in particular to an automatic separation mechanism for adhered magnetic cores. Background Art

[0002] In the manufacturing process of magnetic components, the magnetic core is a key component, and its quality and performance play a decisive role in the overall component. In actual production, the production of magnetic cores requires a series of complex processes, including powdering, pressing, and sintering. After sintering, some cores may become stuck. If these stuck cores are not effectively separated, they will not meet the requirements of subsequent production, processing, and product use.

[0003] Currently, separating stuck magnetic cores relies primarily on manual labor. Specifically, workers use a blade to mechanically separate the cores along the gap between the sticking points. This involves placing the stuck cores on a platform, holding a blade, and using their experience and skills to accurately locate the gap and forcefully separate the cores. This method has many disadvantages: First, the efficiency of manual operation is extremely low, which is difficult to meet the speed requirements of large-scale industrial production and seriously restricts the production progress; that is, a single separation takes a long time and cannot match the rhythm of the automated production line; second, the accuracy of manual separation is difficult to guarantee. Due to differences in the technical level and operating status of the operators, it is easy to cause deviations in the size and shape of the separated magnetic cores, affecting the consistency of product quality; that is, uneven manual operation force causes the breakage rate of the magnetic core corners to be as high as 20%, and the yield rate is only maintained at around 80%; third, long-term engagement in this repetitive and high-intensity manual labor will cause great strain on the operators' bodies, especially their hands, which is not conducive to the occupational health of employees; fourth, labor costs continue to rise over time, that is, a single production line needs to be equipped with several full-time separation operators, and the labor cost accounts for more than 15% of the total cost, which undoubtedly increases the production cost of the enterprise and reduces the competitiveness of the enterprise in the market. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, the present invention proposes an automatic separation mechanism for adhered magnetic cores, which can operate 24 hours a day to effectively improve efficiency, increase production capacity, reduce labor costs, achieve cost reduction and efficiency improvement, improve separation yield, and help enterprises save costs.

[0005] The technical solution adopted in the present invention is:

[0006] A mechanism for automatically separating adhered magnetic cores comprises a frame, on which are mounted a feeding mechanism for vibrating discharging, a clamping mechanism, a breaking mechanism, and a discharge bin; the outlet of the feeding mechanism is provided with the clamping mechanism capable of clamping the adhered magnetic core workpiece; the front side of the clamping mechanism is provided with the breaking mechanism for cooperating with it to separate the magnetic cores; the discharge bin is provided below the breaking mechanism; the breaking mechanism comprises a first clamping cylinder capable of clamping the outermost magnetic core of the adhered magnetic core workpiece and performing a breaking action; the first clamping cylinder is connected to a first breaking cylinder that drives it to perform the breaking action; the first clamping cylinder and the first breaking cylinder are both mounted on a breaking bracket; the breaking bracket is connected to a second breaking cylinder that drives it to approach or move away from the clamping mechanism.

[0007] Furthermore, the first clamping cylinder is fixed to one end of the first clamping cylinder bracket, and the other end of the first clamping cylinder bracket is connected to the obliquely arranged first breaking cylinder via a universal coupling. Movable bearings are provided on both sides of the first clamping cylinder bracket, and the movable bearings are mounted in vertical arcuate grooves on the breaking bracket for vertical sliding. In the present invention, the first breaking cylinder drives the other end of the first clamping cylinder bracket to move obliquely upward via the universal coupling, thereby causing the first clamping cylinder bracket to rotate the first clamping cylinder at a certain angle to break the magnetic core.

[0008] Furthermore, a clamping claw driven by the output shaft of the first clamping cylinder to achieve a clamping action or a loosening action is installed on the output shaft of the first clamping cylinder.

[0009] Furthermore, a workpiece blocking cylinder is mounted on one side of the breaking mechanism, capable of positioning the adhered magnetic core workpiece at the clamping mechanism. The present invention uses the workpiece blocking cylinder to position the adhered magnetic core workpiece, allowing the clamping mechanism to properly clamp the second magnetic core (counting from the outside inward) of the adhered magnetic core workpiece. This allows the first clamping cylinder to clamp the outermost magnetic core of the adhered magnetic core workpiece, thereby breaking the outermost magnetic cores one by one.

[0010] Furthermore, the workpiece blocking cylinder is connected to a front and rear adjustment screw that can drive it to move and adjust the distance between it and the clamping mechanism. The front and rear adjustment screw is installed on the breaking bracket, so that it can be suitable for bonding magnetic core workpieces of different lengths and sizes.

[0011] Furthermore, the clamping mechanism includes a second clamping cylinder, the output shaft of which is equipped with a clamping tooling that is driven by the second clamping cylinder to realize clamping or releasing action, and one side of the clamping tooling is provided with an incoming material detection sensor that senses whether the adhesive magnetic core workpiece is in place.

[0012] Furthermore, a cleaning air blow pipe for blowing away magnetic core fragments is provided on the other side of the clamping tool.

[0013] Furthermore, the feeding mechanism includes a feeding conveyor belt, a first high-frequency vibrator platform is provided at the end of the feeding conveyor belt, a second high-frequency vibrator platform is installed at the output end of the first high-frequency vibrator platform, and the clamping mechanism is provided at the output end of the second high-frequency vibrator platform.

[0014] Furthermore, the second high-frequency vibrator platform is provided with a screening device, and a recycling box is provided below the screening device.

[0015] Furthermore, a discharge detection sensor for detecting whether a magnetic core passes through is provided at the end of the feeding conveyor belt, and a material detection sensor for detecting whether a magnetic core passes through is provided on one side of the first high-frequency vibrator platform. When the discharge detection sensor detects that a magnetic core passes through, the first high-frequency vibrator platform is started. When the material detection sensor identifies the magnetic core, the second high-frequency vibrator platform is started. When the discharge detection sensor and the material detection sensor do not identify the magnetic core within a certain period of time, the first high-frequency vibrator platform stops vibrating.

[0016] The beneficial effects of the present invention are: it can operate 24 hours a day, thereby effectively improving efficiency, increasing production capacity, reducing labor costs, achieving cost reduction and efficiency improvement, improving separation yield, and helping enterprises save costs.

[0030] Reference Figure 1-8 The present embodiment provides an automatic separation mechanism for adhered magnetic cores, including a frame 1, on which are installed a feeding mechanism 2 for vibrating discharging, a clamping mechanism 3, a breaking mechanism 4, and a discharge bin 5. The outlet of the feeding mechanism 2 is provided with the clamping mechanism 3 capable of clamping the adhered magnetic core workpiece 6, the front side of the clamping mechanism 3 is provided with the breaking mechanism 4 for cooperating with it to separate the magnetic cores, and the discharge bin 5 is provided below the breaking mechanism 4.

[0031] The breaking mechanism 4 described in this embodiment includes a first clamping cylinder 41 that can clamp the outermost magnetic core of the adhered magnetic core workpiece and perform the breaking action. The first clamping cylinder 41 is connected to the first breaking cylinder 43 that drives it to perform the breaking action. The first clamping cylinder 41 and the first breaking cylinder 43 are both installed on a breaking bracket 50. The breaking bracket 50 is connected to a second breaking cylinder 44 that drives it to move closer to or away from the clamping mechanism 3. Specifically, the first clamping cylinder 41 is fixed to one end of the first clamping cylinder bracket 46, and the other end of the first clamping cylinder bracket 46 is connected to the obliquely arranged first breaking cylinder 43 through a universal coupling 45. Movable bearings 47 are provided on both sides of the first clamping cylinder bracket 46. The movable bearings 47 can be installed in the vertical arc groove on the breaking bracket 50 so as to slide up and down. In this invention, a first breaking cylinder 43 drives the other end of a first clamping cylinder bracket 46 via a universal joint 45, moving it diagonally upward. This causes the first clamping cylinder bracket 46 to rotate the first clamping cylinder 41 to a certain angle, breaking the magnetic core. The output shaft of the first clamping cylinder 41 is mounted with a clamping jaw 42, which it drives to clamp and release the magnetic core. When the clamping jaw 42 grasps the magnetic core, the breaking mechanism 4 executes the breaking action. After breaking, the clamping jaw 42 releases, allowing the magnetic core to fall into the lower hopper 5.

[0032] In this embodiment, two guide plates 51 with buffering are provided between the unloading bin 5 and the breaking mechanism 4 , and the guide plates 51 are staggered and arranged obliquely.

[0033] One side of the breaking mechanism 4 described in this embodiment is equipped with a workpiece blocking cylinder 49 that can position the bonded magnetic core workpiece 6 at the clamping mechanism 3. The present invention positions the bonded magnetic core workpiece 6 by the workpiece blocking cylinder 49, so that the clamping mechanism 3 can correctly clamp the second magnetic core of the bonded magnetic core workpiece 6 (counted from the outside to the inside), thereby enabling the first clamping cylinder 41 to clamp the outermost magnetic core of the bonded magnetic core workpiece 6 and thus break the outermost magnetic cores one by one. The workpiece blocking cylinder 49 is connected to a front and rear adjustment screw 48 that can be driven to move and adjust the distance between it and the clamping mechanism 3. The front and rear adjustment screw 48 is installed on the breaking bracket 50, so that it can be used for bonded magnetic core workpieces 6 of different lengths and sizes. Specifically, the workpiece blocking cylinder 49 is connected to the nut of the front and rear adjustment screw 48 through a cylinder bracket. A blocking rod is provided on the output shaft of the workpiece blocking cylinder 49. The blocking rod is extended to block the workpiece. After the clamping mechanism 3 is clamped, it retracts without affecting the action of the first clamping cylinder 41.

[0034] The clamping mechanism 3 described in this embodiment includes a second clamping cylinder 31, and the output shaft of the second clamping cylinder 31 is equipped with a clamping fixture 32 driven by the second clamping cylinder 31 to realize clamping or loosening action. One side of the clamping fixture 32 is provided with an incoming material detection sensor 33 for sensing whether the bonded magnetic core workpiece 6 is in place. The other side of the clamping fixture 32 is provided with a cleaning air blow pipe 34 for blowing away magnetic core fragments. When the bonded magnetic core workpiece 6 is transported by the feeding mechanism 2 and the front end is identified by the incoming material detection sensor 33, the second clamping cylinder 31 moves downward with the clamping fixture 32 to fix the bonded magnetic core workpiece 6 in the current position. The cleaning air blow pipe 34 blows away the magnetic core fragments inside the clamping mechanism 3 and the breaking mechanism 4 to ensure that it is clamped in place next time.

[0035] The loading mechanism 2 described in this embodiment includes a loading conveyor belt 21, and a first high-frequency vibrator platform 24 is provided at the end of the loading conveyor belt 21. A second high-frequency vibrator platform 25 is installed at the output end of the first high-frequency vibrator platform 24, and the clamping mechanism 3 is arranged at the output end of the second high-frequency vibrator platform 25. The second high-frequency vibrator platform 25 is provided with a screening device, and a recycling box 26 is provided below the screening device. Specifically, the first high-frequency vibrator platform 24 has a first vibration discharge channel 27 for receiving magnetic cores, and the second high-frequency vibrator platform 25 has a second vibration discharge channel 28 for receiving magnetic cores. The first vibration discharge channel 27 and the second vibration discharge channel 28 are connected to form a straight line and are arranged perpendicular to the loading conveyor belt 21. The screening device is a notch structure, that is, a notch is provided on the second vibration discharge channel 28, and the length of the notch is less than the length of the adhesion magnetic core workpiece 6 in normal production. The end of the feeding conveyor belt 21 is provided with a discharge detection sensor 22 for detecting whether a magnetic core passes through, and one side of the first high-frequency vibrator platform 24 is provided with a material detection sensor 23 for detecting whether a magnetic core passes through. When the discharge detection sensor 22 detects that a magnetic core passes through, the first high-frequency vibrator platform 24 is started. When the material detection sensor 23 identifies the magnetic core, the second high-frequency vibrator platform 25 is started. When the discharge detection sensor 22 and the material detection sensor 23 do not identify the magnetic core within a certain period of time (for example, within 10S), the first high-frequency vibrator platform 24 stops vibrating.

[0036] The bottom of the rack 1 of this embodiment is provided with a plurality of sets of universal wheels 11 that can be used for pushing and moving, and a plurality of sets of support legs 12 that can be positioned and adjusted in height.

[0037] The feeding conveyor belt 21, the front and rear adjustment screw rods 48, etc. described in this embodiment are all driven by corresponding motors.

[0038] The working principle of the present invention is as follows:

[0039] After sintering, the bonded magnetic core workpiece 6 is manually placed on the loading conveyor belt 21. The bonded magnetic core workpiece 6 is transported to the front end of the loading conveyor belt 21 by the loading conveyor belt 21. At this time, the discharge detection sensor 22 detects that the bonded magnetic core workpiece 6 has passed through and activates the first high-frequency vibrator platform 24. At the same time, the material detection sensor 23 recognizes the bonded magnetic core workpiece 6 and activates the second high-frequency vibrator platform 25. The bonded magnetic core workpiece 6 passes through the first vibration discharge channel 27 and the second vibration discharge channel 28 in turn. The bonded magnetic core workpiece 6 that does not meet the workpiece length will fall into the recovery box 26. When the discharge detection sensor 22 and the material detection sensor 23 do not recognize the material within 10 seconds, the first high-frequency vibrator platform 24 stops vibrating.

[0040] The second breaking cylinder 44 extends to move the entire mechanism to the breaking position, the workpiece blocking cylinder 49 extends, and the blocking rod extends to the front side of the clamping tool 32. The second vibrating discharging channel 28 transports the adhered magnetic core workpiece 6 to the blocking rod. After the incoming material detection sensor 33 recognizes that it is in place, the clamping tool 32 fixes the second magnetic core workpiece and the workpiece blocking cylinder 49 retracts; the jaws 42 of the first clamping cylinder 41 clamp the first magnetic core workpiece, and the first breaking cylinder 43 extends. Under the action of the universal coupling 45, the movable bearing 46 slides in the slot, and the first clamping cylinder 41 flips over to complete the breaking action; the second breaking cylinder 44 retracts, and at the same time, the jaws 42 of the first clamping cylinder 41 open, and the first magnetic core workpiece falls into the lower bin 5 along the guide plate 51 under the action of gravity. The first breaking cylinder 43 retracts, and then the second breaking cylinder 44 extends. At this time, the second high-frequency vibrator platform 25 is continuously vibrating, outputting the adhered magnetic core workpiece 6 forward, and the workpiece blocking cylinder 49, the second clamping cylinder 31, the first clamping cylinder 41, and the first breaking cylinder 43 act in sequence to complete the breaking action again. This action is then continuously repeated to separate the magnetic cores of the adhered magnetic core workpiece 6 one by one.

[0041] The present invention can operate 24 hours a day, thereby effectively improving efficiency, increasing production capacity, reducing labor costs, achieving cost reduction and efficiency improvement, improving separation yield, and helping enterprises save costs.
