Description

Technical Field

[0001] The invention belongs to the technical field of magnetic core and blade assembly, and in particular relates to a high-precision automatic assembly system for magnetic core components. Background Art

[0002] The magnetic core is one of the important components of the gas valve. Before assembling the magnetic core with the valve housing, valve sleeve and other components, the blade needs to be pre-pressed and installed on one end of the magnetic core. In order to improve the assembly efficiency of the magnetic core and the blade, the existing technology center has also disclosed many devices for automating the assembly of the magnetic core.

[0003] For example, the patent number "CN103177865A" and the name "A magnetic core assembly machine" discloses a magnetic core assembly device, which transports the magnetic core assembly between different workstations through a conveyor belt, and picks up the magnetic core for installation through an installation unit. However, the above-mentioned prior art does not solve the technical problem of the requirements for the orientation of the magnetic core when the magnetic core and the blade are pressed together. At the same time, during the pressing and dispensing process, it is very easy for impurities to remain inside the magnetic core and cannot be removed, thereby affecting the quality of the magnetic core.

[0004] For example, the patent number "CN108890260A" and the name "A high-precision automated assembly system for magnetic core components" discloses an automatic assembly device for magnetic cores, which picks up the magnetic cores through the cooperation of a linear moving mechanism and a clamp, and presses the magnetic cores through a press-fit device. However, in the above-mentioned prior art, the magnetic cores are directly clamped only through the cooperation of a three-axis moving device and a picking air claw, but once the magnetic core is in the wrong direction, the clamp still clamps the magnetic core in the wrong direction for subsequent assembly. At the same time, the above-mentioned prior art also cannot avoid the problem that impurities enter the magnetic core during the assembly process and cannot be removed.

[0005] Aiming at the defects of the traditional magnetic core assembly device that the correct orientation of the magnetic core cannot be ensured and the impurities inside the magnetic core cannot be removed, the present invention discloses a high-precision automatic assembly system for magnetic core components. Summary of the invention

[0006] The object of the present invention is to provide a high-precision automated assembly system for a magnetic core assembly, which can realize efficient and continuous pressing and assembling of the magnetic core and the blades in the correct orientation, while effectively avoiding the accumulation of slag in the magnetic core.

[0007] The present invention is achieved through the following technical solutions:

[0008] A high-precision automated assembly system for a magnetic core component, for assembling magnetic cores and blades, comprises a rotating stage, on which a plurality of carrier seats with positioning holes are circumferentially arranged, and further comprises a blade loading device, a magnetic core loading device, a magnetic core-blade pressing device, and a magnetic core purging device arranged along the rotation direction of the rotating stage, wherein the blade loading device is used to pick up the blades and place the blades at the bottom of the positioning hole on the carrier seat; the magnetic core loading device is used to horizontally load the magnetic core in the correct direction and adjust the magnetic core to a vertical state and coaxially place it at the top of the blade in the positioning hole; the pressing end of the magnetic core-blade pressing device is arranged corresponding to the positioning hole of the carrier seat and presses the magnetic core and the blade downwardly; the magnetic core purging device comprises a sealing portion with an air port arranged corresponding to the top of the positioning hole of the carrier seat and an air suction portion arranged corresponding to the bottom of the positioning hole of the carrier seat, the sealing portion is used to seal the positioning hole with the top of the magnetic core, and the air suction portion is used to seal the bottom of the positioning hole and inhale air.

[0009] The rotating stage drives the carrier to circumferentially move in a circular motion among the blade loading device, the core loading device, the core blade pressing device, and the core purging device. The blade loading device picks up the blade and places it at the bottom of the positioning hole on the carrier. The core loading device is used to pick up the core horizontally, replacing the traditional mode of picking up the core vertically, so as to avoid the opening of the core being directly oriented vertically, thereby effectively preventing external impurities from directly entering the core during the core transportation process. At the same time, the core loading device detects the orientation of the core, picks up the core with the correct orientation, and does not pick up the core with the wrong orientation, thereby ensuring the correct orientation of the subsequent core assembly.

[0010] Then, the magnetic core with the correct orientation is adjusted from a horizontal state to a vertical state through the magnetic core feeding device, and the magnetic core of the vertical device is placed in the positioning hole so that the bottom end of the magnetic core contacts the blade. The pressing end of the magnetic core blade pressing device presses the top of the magnetic core downward, and then presses and assembles the magnetic core and the blade. The sealing part and the air suction part of the magnetic core blowing device are respectively arranged on the upper and lower sides of the positioning hole. The sealing part moves downward to wrap and seal the top of the magnetic core, and the air suction part moves upward to wrap and seal the bottom of the positioning hole, and then air is sucked through the air suction part, thereby generating negative pressure inside the magnetic core. Since an air port is provided on the sealing part, the air flow passes through the inside of the magnetic core from top to bottom through the air port under the action of the negative pressure inside the magnetic core, and then the slag inside the magnetic core is sucked out to ensure that there is no slag inside the magnetic core.

[0011] Furthermore, in order to better realize the present invention, the sealing part includes a vertical pressing device and a sealing sleeve. The pressing end of the vertical pressing device is arranged corresponding to the top of the positioning hole, and a sealing sleeve is arranged on the pressing end. The sealing sleeve is arranged corresponding to the outside of the magnetic core, and an air port is arranged on the sealing sleeve.

[0012] Furthermore, in order to better realize the present invention, the suction part includes a vertical lifting device, a sealing suction cup, and a suction device. The vertical lifting device is used to drive the sealing suction cup to contact and seal with the bottom of the positioning hole. The sealing suction cup is provided with a suction hole connected to the positioning hole, and the end of the suction hole away from the positioning hole is connected to the suction device.

[0013] Furthermore, in order to better realize the present invention, the magnetic core loading device includes a horizontal magnetic core loading device, a magnetic core rotating device, and a magnetic core translation device. The horizontal magnetic core loading device is used to horizontally eject the magnetic core, and the magnetic core rotating device is provided with a magnetic core rotating device at the discharge end corresponding to the horizontal magnetic core loading device. The magnetic core rotating device is used to pick up the horizontal magnetic core and drive the horizontal magnetic core to rotate to a vertical state; the magnetic core translation device is used to pick up the magnetic core rotated to a vertical state by the magnetic core rotating device and translate the magnetic core to place it in the positioning hole on the carrier seat.

[0014] Furthermore, in order to better realize the present invention, the horizontal magnetic core loading device includes a magnetic core loading rack, a magnetic core ejecting device, and a magnetic core shielding device. The magnetic core loading rack is provided with a plurality of horizontal magnetic core placing grooves for horizontally placing magnetic cores, and a horizontal magnetic core pushing channel is provided at the bottom of the horizontal magnetic core placing groove. A magnetic core shielding device for shielding the magnetic cores and allowing the magnetic cores to enter the horizontal magnetic core pushing channel one by one horizontally is provided at one end of the horizontal magnetic core placing groove close to the horizontal magnetic core pushing channel. A magnetic core ejecting device for ejecting the magnetic core toward the other end is provided at one end of the horizontal magnetic core pushing channel, and a magnetic core rotating device is provided at the other end of the horizontal magnetic core pushing channel.

[0015] Furthermore, in order to better implement the present invention, a foolproof limit plate is provided at the top of the horizontal magnetic core placement groove, and a foolproof limit chamfer is provided on the foolproof limit plate corresponding to the magnetic core.

[0016] Furthermore, in order to better realize the present invention, the magnetic core rotation device includes a stepping rotating motor and a magnetic core rotation sleeve. A magnetic core rotation sleeve is arranged on the rotating end of the stepping rotating motor. The magnetic core rotation sleeve is evenly arranged along the circumference with directional magnetic core sleeves arranged at the discharge end of the magnetic core horizontal feeding device. A built-in pneumatic clamp is arranged inside the directional magnetic core sleeve. The built-in pneumatic clamp clamps the magnetic core with the correct direction and does not clamp the magnetic core with the wrong direction.

[0017] Furthermore, in order to better realize the present invention, the built-in pneumatic clamp includes a directional microswitch, a pneumatic chuck, an air inlet valve, an exhaust valve, a reset spring, and an air suction pump. A directional microswitch is arranged at the bottom of the directional magnetic core sleeve, and a radial mounting groove and an air inlet channel and an exhaust channel connected to the radial mounting groove are arranged on the side wall of the directional magnetic core sleeve. A pneumatic chuck is arranged in the radial mounting groove for radial sliding, and a reset spring is arranged between the pneumatic chuck and the bottom of the radial mounting groove; the air inlet end of the air inlet channel is connected to the air suction pump, an air inlet valve is arranged on the air inlet channel, and an exhaust valve is arranged on the exhaust channel.

[0018] Furthermore, in order to better realize the present invention, the magnetic core blade pressing device includes a stamping electric cylinder, a stamping head, and a stamping corrector. The stamping electric cylinder and the stamping corrector are coaxially arranged on the upper and lower sides of the positioning hole, and a stamping head is arranged on the stamping end of the stamping electric cylinder corresponding to the top of the magnetic core; the rotating stage is also provided with a correction hole for the stamping end of the stamping electric cylinder to press down through.

[0019] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0020] (1) The present invention provides a horizontal magnetic core placement groove on the magnetic core loading rack so that the magnetic core enters the interior of the horizontal magnetic core pushing channel in a horizontal state, and uses a magnetic core ejecting device to push the horizontal magnetic core to the magnetic core rotating device for picking up and rotating, so that the magnetic core remains in a horizontal state during transportation, thereby preventing the opening of the magnetic core from being oriented vertically, causing external impurities to directly enter the interior of the magnetic core; at the same time, the present invention provides a direction micro switch at the bottom of the directional magnetic core sleeve, so that only the magnetic core with the correct orientation can turn on the direction micro switch, thereby allowing the pneumatic chuck to extend and clamp the magnetic core, while the magnetic core with the wrong orientation cannot turn on the direction micro switch, thereby allowing the pneumatic chuck to retract and not hold the magnetic core, thereby ensuring that only the magnetic core with the correct orientation is rotated and transported to the magnetic core translation device, thereby preventing the magnetic core with the wrong orientation from participating in subsequent assembly;

[0021] (2) The present invention provides a magnetic core blowing device including a sealing part and an air suction part. The sealing sleeve is driven by a vertical downward pressing device in the sealing part to seal the top of the magnetic core. The sealing suction cup is lifted upward by a vertical lifting device in the air suction part, so that the sealing suction cup seals the bottom of the positioning hole. Then, the air inside the magnetic core is sucked out by the air suction device to form a negative pressure. The air intake on the air port of the sealing sleeve is coordinated to form an air flow flowing from top to bottom in the magnetic core, thereby effectively blowing out the slag inside the magnetic core.

The core loading device 4 is correspondingly arranged on one side of the core loading station. The core loading device 4 is used to pick up the core horizontally, and then adjust the core to a vertical state, and then place the vertical core in the positioning hole so that the bottom of the core contacts the top of the blade. The core blade pressing device 5 is correspondingly arranged on one side of the core assembly station.

[0032] Embodiment 2:

[0033] This embodiment is further optimized on the basis of embodiment 1. Figure 1 , Figure 5 , Figure 6 As shown, the sealing part includes a vertical pressing device 611 and a sealing sleeve 612. The pressing end of the vertical pressing device 611 is arranged corresponding to the top of the positioning hole, and the sealing sleeve 612 is arranged on the pressing end. The sealing sleeve 612 is arranged corresponding to the outside of the magnetic core, and the sealing sleeve 612 is provided with an air port.

[0034] When the vertical pressing device 611 drives the sealing sleeve 612 to press down, the sealing sleeve 612 is wrapped around the outside of the magnetic core. At this time, the outer wall of the magnetic core contacts the inner wall of the sealing sleeve 612, thereby sealing the top of the magnetic core. In order to further improve the sealing effect, an elastic sealing ring is provided on the inner side wall of the bottom opening of the sealing sleeve 612, thereby making the inner wall of the sealing sleeve 612 and the outer wall of the magnetic core fit more closely.

[0035] Furthermore, the vertical pressing device 611 is a vertical pressing cylinder.

[0036] The suction part includes a vertical lifting device 621, a sealing suction cup 622, and a suction device 623.

The sealing suction cup 622 is provided with a suction hole connected to the positioning hole, and the end of the suction hole away from the positioning hole is connected to the suction device 623.

[0037] After the vertical lifting device 621 drives the sealing suction cup 622 to rise, the top of the sealing suction cup 622 is closely fitted with the bottom end face of the positioning hole, thereby sealing the bottom of the positioning hole. At this time, the top of the suction hole inside the sealing suction cup 622 is connected to the bottom end of the positioning hole. Then, the suction device 623 performs suction operation, so that negative pressure is formed inside the magnetic core, and then the external air is sucked into the magnetic core from top to bottom through the air port on the sealing sleeve 612, and then the slag inside the magnetic suction is blown out by the flow of air from top to bottom.

[0038] Furthermore, a debris cover connected to the bottom of the air intake hole is provided at the bottom of the sealing suction cup 622, a storage cavity is provided inside the debris cover, and a filter is provided inside the storage cavity. After the airflow passes through the inside of the magnetic core, it passes downward through the air intake hole and enters the debris cover, where the debris is filtered and intercepted by the filter, so that the debris is retained in the storage cavity inside the debris cover, thereby preventing the debris from overflowing and polluting the working area.

[0039] Furthermore, the vertical lifting device 621 is a lifting cylinder, and the air suction device 623 is an air suction pump.

[0043] Several magnetic cores are placed horizontally inside the magnetic core horizontal feeding device 41. The magnetic core horizontal feeding device 41 pushes the horizontal magnetic cores out to the magnetic core rotating device 42 in sequence. The magnetic core rotating device 42 picks up the horizontal magnetic cores and detects the orientation of the magnetic cores. If the orientation of the magnetic cores is correct, the magnetic cores are driven to rotate to a vertical state, and then the magnetic cores are transplanted to the inside of the positioning holes by the magnetic core translation device 43. If the orientation of the magnetic cores is wrong, the magnetic cores are driven to rotate and fall to the NG area for recycling.

[0044] The other parts of this embodiment are the same as those of the above-mentioned embodiment 1 or 2, and thus will not be described in detail.

The magnetic core ejecting device 412 for ejecting the magnetic core toward the other end is provided at one end of the horizontal magnetic core pushing channel, and a magnetic core rotating device 42 is provided at the other end of the horizontal magnetic core pushing channel.

[0047] A plurality of horizontal magnetic cores are stacked in the horizontal magnetic core placement slot, and a magnetic core shielding device 413 is arranged at the connection between the bottom of the horizontal magnetic core placement slot and the horizontal magnetic core push channel. The magnetic core shielding device 413 includes a telescopic cylinder and a shielding sheet, and the shielding sheet is driven by the telescopic cylinder to shield or open the bottom of the horizontal magnetic core placement slot, thereby allowing the horizontal magnetic cores to enter the horizontal magnetic core push channel in sequence.

[0048] The magnetic core ejecting device 412 includes a horizontal pushing cylinder and a pushing head. The pushing head is slidably arranged inside the horizontal magnetic core pushing channel. The horizontal pushing cylinder drives the pushing head to slide horizontally along the horizontal magnetic core pushing channel, thereby pushing the horizontal magnetic core inside the horizontal magnetic core pushing channel to the other end for discharge.

[0049] Furthermore, an anti-foolproof limit plate is provided at the top of the horizontal magnetic core placement groove, and an anti-foolproof limit chamfer is provided on the anti-foolproof limit plate corresponding to the magnetic core, and the anti-foolproof limit chamfer corresponds to the chamfer setting at one end of the magnetic core, thereby pre-positioning the orientation of the magnetic core through physical limitation.

[0050] The other parts of this embodiment are the same as any one of the above embodiments 1-3, so they are not repeated here.

[0051] Embodiment 5:

[0052] This embodiment is further optimized based on any one of the above embodiments 1-4. Figure 3 As shown, the magnetic core rotating device 42 includes a stepping rotating motor 421 and a magnetic core rotating sleeve 422. The magnetic core rotating sleeve 422 is arranged on the rotating end of the stepping rotating motor 421.

The interior of the directional magnetic core sleeve is provided with a built-in pneumatic clamp, and the built-in pneumatic clamp clamps the magnetic core with the correct direction and does not clamp the magnetic core with the wrong direction.

[0053] The core rotating sleeve 422 is driven by the stepping rotating motor 421 to rotate, so that the directional core sleeve arranged in the circumferential direction is aligned with the discharge end of the horizontal core pushing channel, and then the horizontal core is pushed into the directional core sleeve by the core ejection device 412. After the horizontal core enters the interior of the directional core sleeve, the core is clamped and fixed by the built-in pneumatic clamp. Then, the stepping rotating motor 421 drives the core rotating sleeve 422 to rotate ninety degrees, so that the horizontal core is rotated and adjusted to a vertical state, and then the vertical core can be picked up and transplanted into the positioning hole by the core translation device 43.

[0054] The other parts of this embodiment are the same as any one of the above embodiments 1-4, so they are not repeated here.

[0055] Embodiment 6:

[0056] This embodiment is further optimized based on any one of the above embodiments 1-5. Figure 4As shown, the built-in pneumatic clamp includes a directional micro switch 001, a pneumatic chuck 002, an air inlet valve 003, an exhaust valve 004, a reset spring 005, and an air suction pump 006. The bottom of the directional magnetic core sleeve is provided with a directional micro switch 001, and the side wall of the directional magnetic core sleeve is provided with a radial mounting groove and an air inlet channel and an exhaust channel connected to the radial mounting groove. A pneumatic chuck 002 is radially slidably arranged in the radial mounting groove, and a reset spring 005 is arranged between the pneumatic chuck 002 and the bottom of the radial mounting groove; the air inlet end of the air inlet channel is connected to the air suction pump 006, the air inlet valve 003 is provided on the air inlet channel, and the exhaust valve 004 is provided on the exhaust channel.

[0057] A chamfer matching groove is provided on one side of the direction micro switch 001 corresponding to the chamfer at one end of the magnetic core. When the horizontal magnetic core enters the interior of the directional magnetic core sleeve in the correct direction, the chamfer squeezes the chamfer matching groove, thereby turning on the direction micro switch 001. At this time, the external controller controls the air intake valve 003 to open and the air exhaust valve 004 to close, and the air suction pump 006 to inhale air, thereby allowing the air flow to enter the radial installation groove to push the pneumatic chuck 002 along the radial direction of the directional magnetic core sleeve, thereby allowing the pneumatic chuck 002 to clamp and fix the magnetic core inside the directional magnetic core sleeve. After the magnetic core rotates to a vertical state, the external controller controls the air exhaust valve 004 to open and the air intake valve 003 to close, and the air suction pump 006 to close. At this time, the gas inside the radial installation groove is discharged, and the reset spring 005 drives the pneumatic chuck 002 to retract and reset, thereby loosening the magnetic core so that the magnetic core translation device 43 can pick up the magnetic core.

[0058] If the horizontal magnetic core enters the directional magnetic core sleeve in the wrong direction, the end of the magnetic core cannot squeeze the chamfered matching groove on the direction micro switch 001. At this time, the direction micro switch 001 is not conductive, and the pneumatic chuck 002 will not extend radially to clamp the magnetic core. When the magnetic core rotates to the bottom of the magnetic core rotating sleeve 422 along with the directional magnetic core sleeve, the magnetic core will fall to the NG area for recovery.

The stamping head 52 is arranged on the stamping end of the stamping electric cylinder 51 corresponding to the top of the magnetic core; the rotating stage 1 is also provided with a correction hole for the stamping end of the stamping electric cylinder 51 to press down through.

[0062] When the magnetic core and the blade need to be pressed together, the stamping electric cylinder 51 drives the stamping head 52 to press down, so that the stamping head 52 pushes down the top of the magnetic core, and then the bottom of the magnetic core is pressed together with the blade. When the number of stamping times of the stamping electric cylinder 51 reaches a preset threshold, the stamping direction of the stamping electric cylinder 51 needs to be corrected. At this time, the rotating stage 1 rotates so that the correction hole moves between the stamping electric cylinder 51 and the stamping corrector 53, and then the stamping end of the stamping electric cylinder 51 drives the stamping head 52 to press down through the correction hole and press together with the correction port on the stamping corrector 53, and the stamping head 52 is axially corrected through the correction port.

[0063] The other parts of this embodiment are the same as any one of the above embodiments 1-6, so they are not repeated here.
