Description

Technical Field

[0001] This invention relates to the field of circuit breaker processing equipment technology, and in particular to a high-precision positioning and assembly system for circuit breaker magnetic components. Background Technology

[0002] Circuit breakers are automatic safety switches for circuits, widely used in various fields. Magnetic components are crucial parts of circuit breakers, primarily used for short-circuit protection. They utilize an electromagnetic trip unit to instantly trigger mechanical tripping under high fault current, quickly disconnecting the circuit. Magnetic components include plate-type and coil-type components. Plate-type components consist of a terminal block, a suction plate, a torsion spring, and a connecting shaft. Existing technologies for assembling magnetic components mainly include two methods: First, manual installation by workers. However, this method is difficult to meet the needs of mass production and is prone to misalignment. Second, automated assembly using mechanical equipment. However, this requires aligning the connecting holes on the terminal block with the connecting holes on the suction plate and torsion spring before inserting the connecting shaft. Existing equipment is prone to misalignment during assembly, leading to defective products. Therefore, a new high-precision positioning and assembly device for magnetic components is needed. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a high-precision positioning and assembly system for circuit breaker magnetic components that can improve assembly accuracy and efficiency.

[0004] The technical solution of this invention: A high-precision positioning and assembly system for circuit breaker magnetic components, comprising a device base, a fixing device connected to the device base, a terminal block feeding device connected to the device base, a suction plate feeding device connected to the device base, a torsion spring feeding device connected to the device base, a connecting shaft feeding device connected to the device base, a discharging device connected to the device base, and a controller. The fixing device includes a first sliding base slidably connected to the device base, a fixing assembly connected to the first sliding base, and a first hydraulic cylinder for driving the first sliding base to move horizontally. The fixing assembly includes a fixing base fixedly connected to the first sliding base, a limiting plate slidably connected to the first sliding base, a second sliding base slidably connected to the first sliding base, and a fixed... The system includes a fixed limiting shaft connected to the second sliding base, a second hydraulic cylinder for driving the limiting plate to move horizontally, and a third hydraulic cylinder for driving the second sliding base to move horizontally. The fixed base has a limiting groove. When the terminal block is placed on the limiting groove, the position of the limiting shaft corresponds to the position of the through hole on the terminal block. The terminal block feeding device, suction plate feeding device, torsion spring feeding device, and connecting shaft feeding device can feed the terminal block, suction plate, torsion spring, and connecting shaft into the limiting groove, respectively. The discharging device can discharge the assembled magnetic assembly from the limiting groove. The controller is electrically connected to the first hydraulic cylinder, the second hydraulic cylinder, the third hydraulic cylinder, the terminal block feeding device, the suction plate feeding device, the torsion spring feeding device, and the connecting shaft feeding device, respectively.

[0005] Using the above technical solution, firstly, the first hydraulic cylinder drives the first sliding base to the corresponding position of the terminal block feeding device. The terminal block feeding device feeds the terminal block into the limiting groove of the fixed base. Then, the suction plate feeding device feeds the suction plate into the limiting groove of the fixed base. Next, the controller controls the second hydraulic cylinder to drive the limiting plate to the corresponding position of the fixed base to further limit the suction plate. Then, the controller controls the third hydraulic cylinder to drive the limiting shaft to insert into the connection hole of the terminal block and the suction plate, thereby ensuring that the connection hole of the terminal block and the suction plate is aligned. Then, the first hydraulic cylinder drives the first sliding base to the corresponding position of the torsion spring feeding device. Then, the third hydraulic cylinder... The cylinder drives the limit shaft to exit the connecting hole, and then the torsion spring is fed to the space between the suction plate and the terminal block by the torsion spring feeding device, ensuring that the connecting holes of the three are aligned. Then, the third hydraulic cylinder drives the limit shaft to insert into the connecting hole. Then, the controller controls the first sliding base to move a certain distance, so that the fixed base moves to the corresponding position of the connecting shaft feeding device. Then, the third hydraulic cylinder drives the limit shaft to exit the connecting hole, and the connecting shaft feeding device inserts the connecting shaft between the torsion spring, the suction plate and the terminal block to complete the assembly work. Finally, the discharging device discharges the assembled magnetic component. Compared with the traditional assembly method, the assembly efficiency is greatly improved. At the same time, the assembly accuracy can be improved, ensuring the product qualification rate.

[0006] A further feature of the present invention is that the terminal block feeding device includes a first rotating vibratory plate connected to the equipment base, a first horizontal vibratory track connected to the first rotating vibratory plate, a first horizontal vibratory motor connected to the first horizontal vibratory track, a third sliding base slidably connected to the equipment base, a fourth sliding base slidably connected to the third sliding base, a first electric clamping claw connected to the fourth sliding base, a fourth hydraulic cylinder for driving the third sliding base to move horizontally, and a fifth hydraulic cylinder for driving the fourth sliding base to move vertically. The movement trajectory of the first electric clamping claw is between the end of the first horizontal vibratory track and the fixed base. The controller is electrically connected to the first horizontal vibratory motor, the first electric clamping claw, the fourth hydraulic cylinder, and the fifth hydraulic cylinder, respectively.

[0007] Using the above technical solution, when the terminal block needs to be fed, firstly, the first rotating vibratory plate feeds the terminal block into the first flat vibratory track, and then the first flat vibratory motor provides power to the first flat vibratory track. The terminal block moves to its end through the first flat vibratory track. Then, the controller controls the fourth and fifth hydraulic cylinders to drive the third and fourth sliding bases to move, so that the position of the first electric clamping claw corresponds to the end of the first flat vibratory track. Then, the first electric clamping claw clamps the terminal block and places it into the limiting groove. This can ensure the automation level of the device and improve processing efficiency.

[0008] A further feature of the present invention is that the suction plate feeding device includes a second rotary vibratory plate, a second horizontal vibratory track connected to the second rotary vibratory plate, a second horizontal vibratory motor connected to the second horizontal vibratory track, a fifth sliding base slidably connected to the equipment base, a sixth sliding base slidably connected to the fifth sliding base, a second electric clamping claw connected to the sixth sliding base, a sixth hydraulic cylinder for driving the fifth sliding base to move horizontally, and a seventh hydraulic cylinder for driving the sixth sliding base to move vertically. The movement trajectory of the second electric clamping claw is between the end of the second horizontal vibratory track and the fixed base. The controller is electrically connected to the second horizontal vibratory motor, the second electric clamping claw, the sixth hydraulic cylinder, and the seventh hydraulic cylinder, respectively.

[0009] Using the above technical solution, when a suction plate needs to be loaded, the suction plate is transmitted to the second horizontal vibration track via the second rotary vibrating plate. The second horizontal vibration motor then provides vibration force to the second horizontal vibration track, causing the suction plate to move to the end of the second horizontal vibration track. The controller then controls the sixth and seventh hydraulic cylinders to drive the fifth and sixth sliding bases to move, thereby causing the second electric clamping claw to move to the end of the second horizontal vibration track and clamp the suction plate, which is then placed into the limiting groove, completing the loading of the suction plate. This greatly improves the automation level of the equipment, reduces labor costs, and increases processing efficiency.

[0010] A further feature of the present invention is that the torsion spring feeding device includes a third rotary vibratory plate, a third horizontal vibratory track connected to the third rotary vibratory plate, a third horizontal vibratory motor connected to the third horizontal vibratory track, a seventh sliding base slidably connected to the equipment base, an eighth sliding base slidably connected to the seventh sliding base, a third electric clamping claw connected to the eighth sliding base, a limiting block slidably connected to the end of the third horizontal vibratory track, an eighth hydraulic cylinder for driving the seventh sliding base to move horizontally, a ninth hydraulic cylinder for driving the eighth sliding base to move vertically, and a tenth hydraulic cylinder for driving the limiting block to move horizontally. The movement direction of the limiting block is perpendicular to the feeding direction of the torsion spring on the third horizontal vibratory track. The limiting block is provided with a positioning groove, which is adapted to the shape and size of the torsion spring to be processed. The controller is electrically connected to the third horizontal vibratory motor, the third electric clamping claw, the eighth hydraulic cylinder, the ninth hydraulic cylinder, and the tenth hydraulic cylinder, respectively.

[0011] Using the above technical solution, when torsion springs need to be fed, firstly, the torsion springs are fed to the third flat vibrating track by the third rotary vibrating plate. The third flat vibrating motor provides vibration force to the third flat vibrating track. When the torsion springs move to the end of the third flat vibrating track, they enter the positioning groove of the limiting block. Then, the tenth hydraulic cylinder drives the limiting block to slide a certain distance, so that the other end of the limiting block blocks the end of the third flat vibrating track. Then, the eighth and ninth hydraulic cylinders drive the seventh and eighth sliding bases to move, so that the third electric clamping claw corresponds to the position of the torsion spring in the positioning groove. The torsion spring is then clamped into the limiting groove of the fixed base. This can prevent the torsion spring from being clamped in a deformed state, thereby improving the assembly accuracy of the magnetic components and increasing the product qualification rate.

[0012] A further feature of the present invention is that the connecting shaft feeding device includes a fifth rotary vibratory plate, a fifth horizontal vibratory track connected to the fifth rotary vibratory plate, a fifth horizontal vibratory motor connected to the fifth horizontal vibratory track, a sixth horizontal vibratory track connected to the equipment base, a sixth horizontal vibratory motor connected to the sixth horizontal vibratory track, a material distribution platform connected to the equipment base, a material distribution block slidably connected to the material distribution platform, a connecting pipe connected to the material distribution platform, a feeding base connected to the other end of the connecting pipe, a push rod slidably connected to the feeding base, an eleventh hydraulic cylinder for driving the material distribution block to move horizontally, and a twelfth hydraulic cylinder for driving the feeding base to move horizontally. The system includes a thirteenth hydraulic cylinder for driving the push rod to move horizontally, a first and a second material passage groove on the feeding base, a connecting pipe connected to the first material passage groove, a push rod slidably connected to the second material passage groove, the first and second material passage grooves communicating with each other, the central axis of the first and second material passage grooves forming a certain angle with each other, a third material passage groove on the material distribution block, and the position of the third material passage groove corresponding to the position of the connecting pipe when the material distribution block slides a certain distance. The controller is electrically connected to the fifth, sixth, eleventh, twelfth, and thirteenth hydraulic cylinders respectively.

[0013] Using the above technical solution, firstly, the connecting shaft is fed to the fifth flat vibrating track via the fifth rotary vibrating disc. Then, the fifth flat vibrating motor provides vibration force to the fifth flat vibrating track, and the connecting shaft is transmitted to the sixth flat vibrating track via the fifth flat vibrating track. The sixth flat vibrating motor then provides vibration force to the sixth flat vibrating track, causing the connecting shaft to enter the third material channel in the material distribution block via the sixth flat vibrating track. The eleventh hydraulic cylinder drives the material distribution block to slide a certain distance, so that the position of the third material channel corresponds to the position of the connecting pipe. Then, the connecting shaft enters the connecting pipe via the third material channel. Since the connecting pipe is connected to the first material channel, and the first material channel is connected to the second material channel, the connecting shaft will enter the second material channel via the first material channel. Then, the controller controls the thirteenth hydraulic cylinder to drive the push rod to move along the second material channel. At the same time, the controller controls the twelfth hydraulic cylinder to drive the loading base to move towards the fixed base, thereby inserting the connecting shaft into the connecting hole between the terminal block, suction plate, and torsion spring. This can automatically complete the loading of the connecting shaft, further improving production efficiency.

[0014] Further features of the present invention: the number of torsion spring feeding devices, fixing components, feeding bases and connecting pipes are all two; the number of third material passages on the material distribution block is two; when one of the third material passages corresponds to the end position of the sixth transverse track, the position of the other third material passage corresponds to the position of one of the connecting pipes; the two torsion spring feeding devices are symmetrically arranged on both sides of the feeding device on the wiring plate; the distance between the two fixing bases is adapted to the distance from the end of the first transverse track to the end of the third transverse track.

[0015] By adopting the above technical solution, since there are two torsion spring feeding devices, two fixing components, two feeding bases and two connecting pipes, and there are two third material passages on the material distribution block, and when one of the third material passages corresponds to the end position of the sixth transverse track, the position of the other third material passage corresponds to the position of one of the connecting pipes, the torsion spring installation work can be carried out on the two fixing components at the same time, which can further improve the production efficiency of the equipment.

[0016] A further embodiment of the present invention includes: the connecting shaft feeding device further comprising a ninth sliding base slidably connected to the equipment base, a tenth sliding base slidably connected to the ninth sliding base, a fourth electric clamping claw connected to the tenth sliding base, an eleventh sliding base slidably connected to the equipment base, a roller movably connected to the bottom of the eleventh sliding base, a rotary motor for driving the roller to rotate, a fourteenth hydraulic cylinder for driving the ninth sliding base to move horizontally, a fifteenth hydraulic cylinder for driving the tenth sliding base to move vertically, and a sixteenth hydraulic cylinder for driving the eleventh sliding base to move horizontally. The distance between the bottom of the roller and the upper surface of the fifth vibration track is adapted to the diameter of the connecting shaft. The roller is positioned corresponding to the end of the fifth vibration track. The movement track of the fourth electric clamping claw is between the fifth and sixth vibration tracks. The controller is electrically connected to the fourteenth, fifteenth, and sixteenth hydraulic cylinders, the rotary motor, and the fourth electric clamping claw, respectively.

[0017] Using the above technical solution, when the connecting shaft is fed to the end of the fifth vibrating track, the controller controls the sixteenth hydraulic cylinder to drive the eleventh sliding base to slide a certain distance, causing the roller to move directly above the connecting shaft. Since existing connecting shafts typically have arc-shaped protrusions at both ends, with a flattened center, this effectively improves the connection stability between the connecting shaft and the connecting hole. Therefore, by rotating the roller via a rotary motor, the position of the arc-shaped protrusions on the connecting shaft is adjusted until the flattened portion of the arc-shaped protrusion faces upwards, and the roller can no longer move it. The connecting shafts move to ensure that the feeding posture of each connecting shaft remains consistent. Then, the controller controls the fourteenth and fifteenth hydraulic cylinders to drive the ninth and tenth sliding bases to move, so that the position of the fourth electric clamping claw corresponds to the position of the connecting shaft located at the end of the fifth vibration track. After the connecting shaft is clamped, it is placed on the sixth vibration track. The sixth vibration motor provides vibration force to the sixth vibration track, so that the connecting shaft enters the material distribution block through the sixth vibration track for material distribution. This can further improve the qualification rate of the processed products.

[0018] A further embodiment of the present invention includes: the discharge device comprising a twelfth sliding base slidably connected to the equipment base; a thirteenth sliding base slidably connected to the twelfth sliding base; a fourteenth sliding base slidably connected to the thirteenth sliding base; a fifth electric clamping jaw connected to the thirteenth sliding base; a sixth electric clamping jaw connected to the fourteenth sliding base; a defective product collection frame connected to the equipment base; a qualified product collection frame connected to the equipment base; a guide plate slidably connected to the equipment base; a seventeenth hydraulic cylinder for driving the twelfth sliding base to move horizontally; an eighteenth hydraulic cylinder for driving the thirteenth sliding base to move vertically; and a guide plate for driving the fourteenth sliding base to move vertically. The sliding base has a nineteenth hydraulic cylinder that moves vertically and a twentieth hydraulic cylinder that drives the guide plate to move obliquely. The distance between the fifth and sixth electric clamping jaws is adapted to the distance between the two fixed bases. When the guide plate is in the initial state, one end of the guide plate corresponds to the position of the qualified product collection box, and the guide plate blocks the defective product collection box. The equipment base is also equipped with a CCD vision inspection instrument, which is located above the fixed base. The controller is electrically connected to the sixth electric clamping jaw, the seventeenth hydraulic cylinder, the eighteenth hydraulic cylinder, the nineteenth hydraulic cylinder, the twentieth hydraulic cylinder, and the CCD vision inspection instrument.

[0019] Using the above technical solution, after processing is completed, the first hydraulic cylinder drives the first sliding base to move a certain distance, thereby moving the fixed base directly below the CCD vision inspection instrument. The CCD vision inspection instrument detects whether the processed magnetic components are qualified. If all products are qualified, the controller controls the seventeenth, eighteenth, and nineteenth hydraulic cylinders to drive the twelfth, thirteenth, and fourteenth sliding bases to move a certain distance, respectively. This causes the fifth and sixth electric clamping jaws to clamp the processed magnetic components on the two fixed bases and move them above the guide plate. The fifth and sixth electric clamping jaws then release simultaneously, transferring the magnetic components through the guide plate to the qualified product collection box. If there are defective products, the controller controls the twentieth hydraulic cylinder to slide the guide plate a certain distance, so that the guide plate no longer blocks the defective product collection box. The magnetic components detected as defective are then placed into the defective product collection box. This achieves automated defective product screening, further improving processing efficiency and the automation level of the equipment. Attached Figure Description

The fixing device 2 includes a first sliding base 9 slidably connected to the equipment base 1, a fixing component 10 connected to the first sliding base 9, and a first hydraulic cylinder 11 for driving the first sliding base 9 to move horizontally. The fixing component 10 includes a fixing base 12 fixedly connected to the first sliding base 9, a limiting plate 13 slidably connected to the first sliding base 9, a second sliding base 14 slidably connected to the first sliding base 9, and a limiting plate 13 fixedly connected to the second sliding base 9. The sliding base 14 has a limiting shaft 15, a second hydraulic cylinder 16 for driving the limiting plate 13 to move horizontally, and a third hydraulic cylinder 17 for driving the second sliding base 14 to move horizontally. The fixed base 12 is provided with a limiting groove 18. When the wiring plate is placed on the limiting groove 18, the position of the limiting shaft 15 corresponds to the position of the through hole on the wiring plate. The wiring plate feeding device 3, the suction plate feeding device 4, the torsion spring feeding device 5, and the connecting shaft feeding device 6 can feed the wiring plate, the suction plate, the torsion spring, and the connecting shaft into the limiting groove 18, respectively. The discharging device 7 can discharge the assembled magnetic assembly from the limiting groove 18. The controller 8 is electrically connected to the first hydraulic cylinder 11, the second hydraulic cylinder 16, the third hydraulic cylinder 17, the wiring plate feeding device 3, the suction plate feeding device 4, the torsion spring feeding device 5, and the connecting shaft feeding device 6, respectively.

[0031] First, the first hydraulic cylinder 11 drives the first sliding base 9 to the corresponding position of the connector plate feeding device 3. The connector plate feeding device 3 feeds the connector plate into the limiting groove 18 of the fixed base 12. Then, the suction plate feeding device 4 feeds the suction plate into the limiting groove 18 of the fixed base 12. Next, the controller 8 controls the second hydraulic cylinder 16 to drive the limiting plate 13 to the corresponding position of the fixed base 12 to further limit the suction plate. Then, the controller 8 controls the third hydraulic cylinder 17 to drive the limiting shaft 15 to insert into the connection hole of the connector plate and the suction plate, thereby ensuring that the connection hole of the connector plate and the suction plate is aligned. Then, the first hydraulic cylinder 11 drives the first sliding base 9 to the corresponding position of the torsion spring feeding device 5. Then, the third hydraulic cylinder 17 drives the first sliding base 9 to the corresponding position of the torsion spring feeding device 5. Cylinder 17 drives the limiting shaft 15 out of the connecting hole. Then, the torsion spring is fed to the space between the suction plate and the wiring plate by the torsion spring feeding device 5, ensuring that the connecting holes of the three are aligned. Then, the limiting shaft 15 is inserted into the connecting hole by the third hydraulic cylinder 17. Then, the controller 8 controls the first sliding base 9 to move a certain distance, so that the fixed base 12 moves to the corresponding position of the connecting shaft feeding device 6. Then, the limiting shaft 15 is driven out of the connecting hole by the third hydraulic cylinder 17. The connecting shaft is inserted between the torsion spring, the suction plate and the wiring plate by the connecting shaft feeding device 6 to complete the assembly work. Then, the assembled magnetic component is discharged by the discharge device 7. Compared with the traditional assembly method, the assembly efficiency is greatly improved. At the same time, the assembly accuracy can be improved, ensuring the product qualification rate.

[0032] The terminal block loading device 3 includes a first rotary vibratory plate 19 connected to the equipment base 1, a first horizontal vibration track 20 connected to the first rotary vibratory plate 19, a first horizontal vibration motor 21 connected to the first horizontal vibration track 20, a third sliding base 22 slidably connected to the equipment base 1, a fourth sliding base 23 slidably connected to the third sliding base 22, a first electric clamping claw 24 connected to the fourth sliding base 23, a fourth hydraulic cylinder 25 for driving the third sliding base 22 to move horizontally, and a fifth hydraulic cylinder 26 for driving the fourth sliding base 23 to move vertically. The movement trajectory of the first electric clamping claw 24 is between the end of the first horizontal vibration track 20 and the fixed base 12. The controller 8 is electrically connected to the first horizontal vibration motor 21, the first electric clamping claw 24, the fourth hydraulic cylinder 25, and the fifth hydraulic cylinder 26, respectively.

[0033] When the terminal block needs to be fed, firstly, the terminal block is fed into the first flat vibrating track 20 by the first rotating vibrating plate 19, and then the first flat vibrating motor 21 provides power to the first flat vibrating track 20. The terminal block moves to its end through the first flat vibrating track 20. Then, the controller 8 controls the fourth hydraulic cylinder 25 and the fifth hydraulic cylinder 26 to drive the third sliding base 22 and the fourth sliding base 23 to move respectively, so that the position of the first electric clamping claw 24 corresponds to the end of the first flat vibrating track 20. Then, the first electric clamping claw 24 clamps the terminal block and places it into the limiting groove 18. This can ensure the automation level of the device and improve the processing efficiency.

[0034] The suction plate feeding device 4 includes a second rotary vibrating plate 27, a second horizontal vibrating track 28 connected to the second rotary vibrating plate 27, a second horizontal vibrating motor 29 connected to the second horizontal vibrating track 28, a fifth sliding base 30 slidably connected to the equipment base 1, a sixth sliding base 31 slidably connected to the fifth sliding base 30, a second electric clamping claw 32 connected to the sixth sliding base 31, a sixth hydraulic cylinder 33 for driving the fifth sliding base 30 to move horizontally, and a seventh hydraulic cylinder 34 for driving the sixth sliding base 31 to move vertically. The movement trajectory of the second electric clamping claw 32 is between the end of the second horizontal vibrating track 28 and the fixed base. The controller 8 is electrically connected to the second horizontal vibrating motor 29, the second electric clamping claw 32, the sixth hydraulic cylinder 33, and the seventh hydraulic cylinder 34, respectively.

[0035] When a suction plate needs to be loaded, the suction plate is transmitted to the second horizontal vibration track 28 via the second rotary vibrating plate 27. The second horizontal vibration motor 29 then provides vibration force to the second horizontal vibration track 28, causing the suction plate to move to the end of the second horizontal vibration track 28. The controller 8 then controls the sixth hydraulic cylinder 33 and the seventh hydraulic cylinder 34 to drive the fifth sliding base 30 and the sixth sliding base 31 to move, thereby causing the second electric clamping claw 32 to move to the end of the second horizontal vibration track 28 and clamp the suction plate. The suction plate is then placed into the limiting groove 18, completing the loading of the suction plate. This greatly improves the automation level of the equipment, reduces labor costs, and increases processing efficiency.

[0036] The torsion spring feeding device 5 includes a third rotary vibratory plate 35, a third horizontal vibration track 36 connected to the third rotary vibratory plate 35, a third horizontal vibration motor 37 connected to the third horizontal vibration track 36, a seventh sliding base 38 slidably connected to the equipment base 1, an eighth sliding base 39 slidably connected to the seventh sliding base 38, a third electric clamping claw 40 connected to the eighth sliding base 39, a limiting block 41 slidably connected to the end of the third horizontal vibration track 36, and an eighth hydraulic cylinder 42 for driving the seventh sliding base 38 to move horizontally. The ninth hydraulic cylinder 43 drives the eighth sliding base 39 to move vertically and the tenth hydraulic cylinder 44 drives the limiting block 41 to move horizontally. The movement direction of the limiting block 41 is perpendicular to the feeding direction of the torsion spring on the third oscillating track 36. The limiting block 41 is provided with a positioning groove 45, which is adapted to the shape and size of the torsion spring to be processed. The controller 8 is electrically connected to the third oscillating motor 37, the third electric clamping claw 40, the eighth hydraulic cylinder 42, the ninth hydraulic cylinder 43 and the tenth hydraulic cylinder 44 respectively.

[0037] When torsion springs need to be fed, firstly, the torsion springs are fed into the third flat vibrating track 36 by the third rotating vibrating disc 35. The third flat vibrating motor 37 provides vibration force to the third flat vibrating track 36. When the torsion springs move to the end of the third flat vibrating track 36, they enter the positioning groove 45 of the limiting block 41. Then, the tenth hydraulic cylinder 44 drives the limiting block 41 to slide a certain distance, so that the other end of the limiting block 41 blocks the end of the third flat vibrating track 36. Then, the eighth hydraulic cylinder 42 and the ninth hydraulic cylinder 43 drive the seventh sliding base 38 and the eighth sliding base 39 to move respectively, so that the third electric clamping claw 40 corresponds to the position of the torsion spring in the positioning groove 45. Then, the torsion springs are clamped into the limiting groove 18 of the fixed base 12. This can prevent the torsion springs from being clamped in a deformed state, thereby improving the assembly accuracy of the magnetic components and increasing the product qualification rate.

[0038] The connecting shaft feeding device 6 includes a fifth rotary vibratory plate 46, a fifth horizontal vibration track 47 connected to the fifth rotary vibratory plate 46, a fifth horizontal vibration motor 48 connected to the fifth horizontal vibration track 47, a sixth horizontal vibration track 49 connected to the equipment base 1, a sixth horizontal vibration motor 50 connected to the sixth horizontal vibration track 49, a material distribution platform 51 connected to the equipment base 1, a material distribution block 52 slidably connected to the material distribution platform 51, a connecting pipe 53 connected to the material distribution platform 51, a feeding base 54 connected to the other end of the connecting pipe 53, a pusher rod 55 slidably connected to the feeding base 54, an eleventh hydraulic cylinder 56 for driving the material distribution block 52 to move horizontally, a twelfth hydraulic cylinder 57 for driving the feeding base 54 to move horizontally, and a pusher rod 55 for driving the pusher rod 56. The thirteenth hydraulic cylinder 58 moves horizontally along the material rod 55. The feeding base 54 is provided with a first material passage 59 and a second material passage 60. The connecting pipe 53 is connected to the first material passage 59. The push rod 55 is slidably connected to the second material passage 60. The first material passage 59 and the second material passage 60 are connected. The central axis of the first material passage 59 and the central axis of the second material passage 60 are at a certain angle. The material distribution block 52 is provided with a third material passage 61. When the material distribution block 52 slides a certain distance, the position of the third material passage 61 corresponds to the position of the connecting pipe 53. The controller 8 is electrically connected to the fifth vibration motor 48, the sixth vibration motor 50, the eleventh hydraulic cylinder 56, the twelfth hydraulic cylinder 57 and the thirteenth hydraulic cylinder 58 respectively.

[0039] First, the connecting shaft is fed to the fifth flat vibrating track 47 via the fifth rotary vibrating disc 46. Then, the fifth flat vibrating motor 48 provides vibration force to the fifth flat vibrating track 47, and the connecting shaft is transmitted to the sixth flat vibrating track 49 via the fifth flat vibrating track 47. The sixth flat vibrating motor 50 then provides vibration force to the sixth flat vibrating track 49, causing the connecting shaft to enter the third feed groove 61 in the material distribution block 52 via the sixth flat vibrating track 49. The eleventh hydraulic cylinder 56 drives the material distribution block 52 to slide a certain distance, so that the position of the third feed groove 61 corresponds to the position of the connecting pipe 53. Then, the connecting shaft passes through the third feed groove 61... 1. The shaft enters the connecting pipe 53. Since the connecting pipe 53 is connected to the first material passage 59 and the first material passage 59 is connected to the second material passage 60, the connecting shaft will enter the second material passage 60 through the first material passage 59. Then, the controller 8 controls the thirteenth hydraulic cylinder 58 to drive the push rod 55 to move along the second material passage 60. At the same time, the controller 8 controls the twelfth hydraulic cylinder 57 to drive the loading base 54 to move towards the fixed base 12, thereby inserting the connecting shaft into the connecting hole between the terminal block, the suction plate and the torsion spring. This can automatically complete the loading of the connecting shaft and further improve production efficiency.

[0040] The number of torsion spring feeding device 5, fixing component 10, feeding base 54 and connecting pipe 53 are all two. The number of third material passage grooves 61 on the material distribution block 52 is two. When one of the third material passage grooves 61 corresponds to the end position of the sixth flat vibration track 49, the position of the other third material passage groove 61 corresponds to the position of one of the connecting pipes 53. The two torsion spring feeding devices 5 are symmetrically arranged on both sides of the feeding device 3 on the wiring plate. The distance between the two fixing bases 12 is adapted to the distance from the end of the first flat vibration track 20 to the end of the third flat vibration track 36.

[0041] Since there are two torsion spring feeding devices 5, two fixing components 10, two feeding bases 54 and two connecting pipes 53, and there are two third material passages 61 on the material distribution block 52, and when one of the third material passages 61 corresponds to the end position of the sixth transverse track 49, the position of the other third material passage 61 corresponds to the position of one of the connecting pipes 53, the torsion spring installation work can be carried out on the two fixing components 10 at the same time, which can further improve the production efficiency of the equipment.

[0042] The connecting shaft feeding device 6 further includes a ninth sliding base 62 slidably connected to the equipment base 1, a tenth sliding base 63 slidably connected to the ninth sliding base 62, a fourth electric clamping claw 64 connected to the tenth sliding base 63, an eleventh sliding base 65 slidably connected to the equipment base 1, a roller 66 movably connected to the bottom of the eleventh sliding base 65, a rotary motor 67 for driving the roller 66 to rotate, a fourteenth hydraulic cylinder 68 for driving the ninth sliding base 62 to move horizontally, and a fifteenth hydraulic cylinder 68 for driving the tenth sliding base 63 to move vertically. Hydraulic cylinder 69 and sixteenth hydraulic cylinder 70 for driving eleventh sliding base 65 to move horizontally, the distance between the bottom of roller 66 and the upper surface of fifth horizontal vibration track 47 is adapted to the diameter of connecting shaft, the position of roller 66 corresponds to the end of fifth horizontal vibration track 47, the movement track of fourth electric clamping claw 64 is between fifth horizontal vibration track 47 and sixth horizontal vibration track 49, and controller 8 is electrically connected to fourteenth hydraulic cylinder 68, fifteenth hydraulic cylinder 69, sixteenth hydraulic cylinder 70, rotary motor 67 and fourth electric clamping claw 64 respectively.

[0043] When the connecting shaft is fed to the end of the fifth vibrating track 47, the controller 8 controls the sixteenth hydraulic cylinder 70 to drive the eleventh sliding base 65 to slide a certain distance, causing the roller 66 to move directly above the connecting shaft. In existing technology, connecting shafts commonly have arc-shaped protrusions at both ends, with a flattened center. This effectively improves the connection stability between the connecting shaft and the connecting hole. Therefore, the rotary motor 67 drives the roller 66 to rotate, thereby adjusting the position of the arc-shaped protrusions on the connecting shaft until the flattened part of the arc-shaped protrusion faces upwards, and the roller 66 can no longer drive the connecting shaft to move. This ensures that the feeding posture of each connecting shaft remains consistent. Then, the controller 8 controls the fourteenth hydraulic cylinder 68 and the fifteenth hydraulic cylinder 69 to drive the ninth sliding base 62 and the tenth sliding base 63 to move respectively. This makes the position of the fourth electric clamping claw 64 correspond to the position of the connecting shaft located at the end of the fifth vibration track 47. After the connecting shaft is clamped, it is placed on the sixth vibration track 49. The sixth vibration motor 50 provides vibration force to the sixth vibration track 49, so that the connecting shaft enters the material distribution block 52 through the sixth vibration track 49 for material distribution. This can further improve the qualification rate of the processed products.

[0044] The discharge device 7 includes a twelfth sliding base 71 slidably connected to the equipment base 1, a thirteenth sliding base 72 slidably connected to the twelfth sliding base 71, a fourteenth sliding base 73 slidably connected to the thirteenth sliding base 72, a fifth electric clamping jaw 74 connected to the thirteenth sliding base 72, a sixth electric clamping jaw 75 connected to the fourteenth sliding base 73, a defective product collection frame 76 connected to the equipment base 1, a qualified product collection frame 77 connected to the equipment base 1, a guide plate 78 slidably connected to the equipment base 1, a seventeenth hydraulic cylinder 79 for driving the twelfth sliding base 71 to move horizontally, an eighteenth hydraulic cylinder 80 for driving the thirteenth sliding base 72 to move vertically, and a fourteenth sliding base 73 for driving the fourteenth sliding base 73 to move vertically. The equipment includes a nineteenth hydraulic cylinder 81 for directional movement and a twentieth hydraulic cylinder 82 for driving the guide plate 78 to move obliquely. The distance between the fifth electric clamping jaw 74 and the sixth electric clamping jaw 75 is adapted to the distance between the two fixed bases 12. When the guide plate 78 is in the initial state, one end of the guide plate 78 corresponds to the position of the qualified product collection box 77, and the guide plate 78 blocks the defective product collection box 76. The equipment base 1 is also equipped with a CCD vision inspection instrument 83, which is located above the fixed base 12. The controller 8 is electrically connected to the sixth electric clamping jaw 75, the seventeenth hydraulic cylinder 79, the eighteenth hydraulic cylinder 80, the nineteenth hydraulic cylinder 81, the twentieth hydraulic cylinder 82, and the CCD vision inspection instrument 83.

[0045] After processing is completed, the first hydraulic cylinder 11 drives the first sliding base 9 to move a certain distance, thereby moving the fixed base 12 directly below the CCD vision inspection instrument 83. The CCD vision inspection instrument 83 checks whether the processed magnetic components are qualified. If the products are qualified, the controller 8 controls the seventeenth hydraulic cylinder 79, the eighteenth hydraulic cylinder 80, and the nineteenth hydraulic cylinder 81 to drive the twelfth sliding base 71, the thirteenth sliding base 72, and the fourteenth sliding base 73 to move a certain distance, thereby causing the fifth electric clamping jaw 74 and the sixth electric clamping jaw 75 to respectively clamp the two The magnetic components processed on the fixed base 12 are clamped and then moved above the guide plate 78. The fifth electric clamping jaw 74 and the sixth electric clamping jaw 75 are released simultaneously, and the magnetic components are transferred through the guide plate 78 to the qualified product collection box 77. If there are defective products, the controller 8 controls the twentieth hydraulic cylinder 82 to drive the guide plate 78 to slide a certain distance, so that the guide plate 78 no longer blocks the defective product collection box 76. The magnetic components detected as defective products are placed into the defective product collection box 76. This can realize the automated defective product screening work, further improve processing efficiency, and improve the automation level of the equipment.
