Description

Technical Field

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

[0002] In the production and manufacturing process of magnetic material components, the magnetic core, as a key component, its quality and performance play a decisive role in the entire component. In actual production, the production of magnetic cores requires a series of complex processes such as powder making, pressing, and sintering. After the sintering process, some magnetic cores will adhere to each other. If these adhered magnetic cores are not effectively separated, they will not meet the requirements of subsequent production and processing as well as product use.

[0003] Currently, for the separation of adhered magnetic cores, it mainly relies on manual operation. Specifically, the operator needs to use a blade to mechanically separate along the adhesion gap. That is, the operator places the adhered magnetic cores on a platform, then holds the blade, and by relying on their own experience and skills, locates the adhesion gap and forces the magnetic cores to be separated. This method has many drawbacks: First, the manual operation efficiency is extremely low, which is difficult to meet the speed requirements of large-scale industrial production and severely restricts the production progress; that is, the single separation takes a long time and cannot match the rhythm of the automated production line. Second, it is difficult to guarantee the accuracy of manual separation. Due to differences in the technical level and operating status of the operators, it is easy to cause deviations in the size, shape, etc. of the separated magnetic cores, affecting the consistency of product quality; that is, the uneven manual operation force results in a magnetic core corner breakage rate as high as 20%, and the qualified product rate only remains at about 80%. Third, long-term engagement in this repetitive and high-intensity manual labor will cause great strain on the operator's body, especially the hands, which is not conducive to the occupational health of employees. Fourth, the labor cost is continuously rising over time; that is, several full-time separation operators need to be configured for a single production line, 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] To overcome the deficiencies of the prior art, the present invention proposes an automatic separation mechanism for adhered magnetic cores, which can run 24 hours a day, thus effectively improving efficiency, increasing production capacity, reducing labor costs, achieving cost reduction and efficiency improvement, enhancing the separation yield, and helping enterprises save costs.

[0005] The technical solution adopted by the present invention is: An automatic separation mechanism for adhered magnetic cores, comprising a frame. An automatic feeding mechanism, a clamping mechanism, a breaking mechanism, and a discharging bin are installed on the frame. The outlet of the automatic feeding mechanism is provided with the clamping mechanism capable of clamping the adhered magnetic core workpiece. The breaking mechanism for magnetic core separation in cooperation with the clamping mechanism is arranged on the front side of the clamping mechanism. The discharging bin is arranged below the breaking mechanism. The breaking mechanism includes 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. Both the first clamping cylinder and the first breaking cylinder are installed 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.

[0006] Furthermore, the first clamping cylinder is fixed at one end of a first clamping cylinder bracket. The other end of the first clamping cylinder bracket is connected to an obliquely arranged first breaking cylinder through a universal coupling. Moving bearings are arranged on both sides of the first clamping cylinder bracket. The moving bearings are slidably installed in vertical arc-shaped grooves on the breaking bracket. In the present invention, the first breaking cylinder drives the other end of the first clamping cylinder bracket to move obliquely upward through the universal coupling, so that the first clamping cylinder bracket drives the first clamping cylinder to flip by a certain angle to break the magnetic core.

[0007] Furthermore, a clamping jaw driven by the output shaft of the first clamping cylinder to perform a clamping action or a releasing action is installed on the output shaft of the first clamping cylinder.

[0008] Furthermore, a workpiece blocking cylinder capable of positioning the adhered magnetic core workpiece at the clamping mechanism is installed on one side of the breaking mechanism. In the present invention, the adhered magnetic core workpiece is positioned by the workpiece blocking cylinder, so that the clamping mechanism can correctly clamp the second magnetic core (counting from the outside to the inside) of the adhered magnetic core workpiece. Thus, the first clamping cylinder can clamp the outermost magnetic core of the adhered magnetic core workpiece to break the outermost magnetic cores one by one.

[0009] Furthermore, the workpiece blocking cylinder is connected to a front-back adjusting screw rod capable of driving it to move and adjust the distance between it and the clamping mechanism. The front-back adjusting screw rod is installed on the breaking bracket, so as to be applicable to adhered magnetic core workpieces of different lengths and sizes.

[0010] Furthermore, the clamping mechanism includes a second clamping cylinder. A clamping tooling driven by the output shaft of the second clamping cylinder to perform a clamping action or a releasing action is installed on the output shaft of the second clamping cylinder. A feeding detection sensor for detecting whether the adhered magnetic core workpiece is in place is arranged on one side of the clamping tooling.

[0011] Furthermore, a cleaning blow pipe for blowing away magnetic core fragments is arranged on the other side of the clamping tooling.

[0012] Furthermore, the feeding mechanism includes a feeding conveyor belt, and 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 arranged at the output end of the second high-frequency vibrator platform.

[0013] Furthermore, a screening device is provided on the second high-frequency vibrator platform, and a recycling bin is arranged below the screening device.

[0014] 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 there is a magnetic core is arranged 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 a magnetic core, the second high-frequency vibrator platform is started. When the discharge detection sensor and the material detection sensor do not identify a magnetic core within a certain period of time, the first high-frequency vibrator platform stops vibrating.

[0015] The beneficial effects of the present invention are as follows: It can operate for 24 hours, thereby effectively improving efficiency, increasing production capacity, reducing labor costs, achieving cost reduction and efficiency improvement, enhancing the separation yield, and helping enterprises save costs.

[0029] Referring to Figure 1-8 , this embodiment provides an automatic separating mechanism for adhered magnetic cores, including a frame 1, on which a feeding mechanism 2 for vibrating and discharging materials, a clamping mechanism 3, a breaking mechanism 4, and a discharging bin 5 are installed. At the outlet of the feeding mechanism 2, there is the clamping mechanism 3 capable of clamping the adhered magnetic core workpiece 6. In front of the clamping mechanism 3, there is the breaking mechanism 4 cooperating with it for magnetic core separation. Below the breaking mechanism 4, there is the discharging bin 5.

[0030] The breaking mechanism 4 in this embodiment includes a first clamping cylinder 41 capable of clamping the outermost magnetic core of the adhered magnetic core workpiece and performing a breaking action. The first clamping cylinder 41 is connected to a first breaking cylinder 43 that drives it to perform the breaking action. Both the first clamping cylinder 41 and the first breaking cylinder 43 are installed on a breaking bracket 50, and the breaking bracket 50 is connected to a second breaking cylinder 44 that drives it to approach or move away from the clamping mechanism 3. Specifically, the first clamping cylinder 41 is fixed at one end of a first clamping cylinder bracket 46. 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. On both sides of the first clamping cylinder bracket 46, there are movable bearings 47, and the movable bearings 47 are slidably installed in vertical arc-shaped grooves on the breaking bracket 50. In the present invention, the first breaking cylinder 43 drives the other end of the first clamping cylinder bracket 46 to move obliquely upward through the universal coupling 45, so that the first clamping cylinder bracket 46 drives the first clamping cylinder 41 to flip by a certain angle to break the magnetic core. On the output shaft of the first clamping cylinder 41, there is a jaw 42 that is driven by it to perform a clamping action or a releasing action. When the jaw 42 clamps the magnetic core, the breaking mechanism 4 can perform the breaking action. After breaking, the jaw 42 releases, and the magnetic core falls into the discharging bin 5.

[0031] Between the discharging bin 5 and the breaking mechanism 4 in this embodiment, there are two guiding plates 51 with buffering, and the guiding plates 51 are arranged obliquely and staggeredly.

[0032] On one side of the breaking mechanism 4 in this embodiment, a workpiece blocking cylinder 49 is installed, which can position the adhered magnetic core workpiece 6 at the clamping mechanism 3. In the present invention, the adhered magnetic core workpiece 6 is positioned by the workpiece blocking cylinder 49, so that the clamping mechanism 3 can correctly clamp the second magnetic core (counting from the outside to the inside) of the adhered magnetic core workpiece 6. Thus, the first clamping cylinder 41 can clamp the outermost magnetic core of the adhered magnetic core workpiece 6 and break the outermost magnetic cores one by one. The workpiece blocking cylinder 49 is connected to a front-back adjusting lead screw 48 that can drive its movement to adjust the distance between it and the clamping mechanism 3. The front-back adjusting lead screw 48 is installed on the breaking bracket 50, so as to be applicable to adhered magnetic core workpieces 6 of different lengths and sizes. Specifically, the workpiece blocking cylinder 49 is connected to the nut of the front-back adjusting lead screw 48 through a cylinder bracket. A blocking rod is provided on the output shaft of the workpiece blocking cylinder 49. Blocking is carried out by the extension of the blocking rod, and it retracts after being clamped by the clamping mechanism 3, without affecting the operation of the first clamping cylinder 41.

[0033] The clamping mechanism 3 in this embodiment includes a second clamping cylinder 31. A clamping tooling 32 driven by the output shaft of the second clamping cylinder 31 to perform clamping or loosening actions is installed on the output shaft of the second clamping cylinder 31. A feeding detection sensor 33 for detecting whether the adhered magnetic core workpiece 6 is in place is arranged on one side of the clamping tooling 32. A cleaning blowpipe 34 for blowing away magnetic core fragments is arranged on the other side of the clamping tooling 32. Under the conveyance of the feeding mechanism 2, when the front end of the adhered magnetic core workpiece 6 is recognized by the feeding detection sensor 33, the second clamping cylinder 31 drives the clamping tooling 32 to move downward to fix the adhered magnetic core workpiece 6 at the current position. The cleaning blowpipe 34 blows away the magnetic core fragments inside the clamping mechanism 3 and the breaking mechanism 4 to ensure that the next clamping is in place.

[0034] In this embodiment, the feeding mechanism 2 includes a feeding conveyor belt 21. A first high-frequency vibrator platform 24 is provided at the end of the feeding conveyor belt 21. The output end of the first high-frequency vibrator platform 24 is equipped with a second high-frequency vibrator platform 25. 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 bin 26 is arranged below the screening device. Specifically, the first high-frequency vibrator platform 24 has a first vibrating discharge channel 27 for receiving magnetic cores, and the second high-frequency vibrator platform 25 has a second vibrating discharge channel 28 for receiving magnetic cores. The first vibrating discharge channel 27 and the second vibrating discharge channel 28 are butted in a straight line and are arranged perpendicular to the feeding conveyor belt 21. The screening device is a notch structure, that is, a notch is provided on the second vibrating discharge channel 28, and the length of the notch is less than the length of the adhered magnetic core workpiece 6 in normal production. An outlet detection sensor 22 for detecting whether a magnetic core passes is arranged at the end of the feeding conveyor belt 21, and a material presence detection sensor 23 for detecting whether there is a magnetic core is arranged on one side of the first high-frequency vibrator platform 24. When the outlet detection sensor 22 detects that a magnetic core passes, the first high-frequency vibrator platform 24 is started. When the material presence detection sensor 23 identifies a magnetic core, the second high-frequency vibrator platform 25 is started. When the outlet detection sensor 22 and the material presence detection sensor 23 do not identify a magnetic core within a certain time (such as within 10S), the first high-frequency vibrator platform 24 stops vibrating.

[0035] At the bottom of the frame 1 of this embodiment, multiple groups of universal wheels 11 that can be used to push and move are provided, and multiple groups of feet 12 that can be positioned and adjust the height are provided.

[0036] In this embodiment, the feeding conveyor belt 21, the front and rear adjustment lead screws 48, etc. are all driven to act by corresponding motors.

[0037] The working principle of the present invention is as follows: An operator puts the adhered magnetic core workpiece 6 after sintering onto the feeding conveyor belt 21. The adhered magnetic core workpiece 6 is conveyed by the feeding conveyor belt 21 to the front end position of the feeding conveyor belt 21. At this time, the outlet detection sensor 22 detects that the adhered magnetic core workpiece 6 passes and starts the first high-frequency vibrator platform 24. At the same time, the material presence detection sensor 23 identifies the adhered magnetic core workpiece 6 and starts the second high-frequency vibrator platform 25. The adhered magnetic core workpiece 6 sequentially passes through the first vibrating discharge channel 27 and the second vibrating discharge channel 28. The adhered magnetic core workpiece 6 that does not meet the workpiece length will fall into the recycling bin 26. When the outlet detection sensor 22 and the material presence detection sensor 23 do not identify the material within 10s, the first high-frequency vibrator platform 24 stops vibrating.

[0038] The second breaking cylinder 44 extends, moving 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 tooling 32. The second vibrating discharge channel 28 conveys the adhered magnetic core workpiece 6 to the blocking rod. After the incoming material detection sensor 33 recognizes that the position is reached, the clamping tooling 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, the first breaking cylinder 43 extends, and under the action of the universal coupling 45, the movable bearing 46 slides in the notch, and the first clamping cylinder 41 flips 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 blanking 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, and the adhered magnetic core workpiece 6 is output forward. 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. By continuously circulating this action, the magnetic cores of the adhered magnetic core workpiece 6 can be separated one by one.

[0039] The present invention can operate for 24 hours, thereby effectively improving efficiency, increasing production capacity, reducing labor costs, achieving cost reduction and efficiency improvement, enhancing the separation yield, and helping enterprises save costs.
