Description

Technical Field

[0001] The present invention belongs to the technical field of magnets, and particularly relates to an assembly method and device for a Halbach magnetic component. Background Art

[0002] For a Halbach magnetic component used in a mobile phone camera, as Figure 1 shown, the magnetic component 1 is composed of 2 magnets with vertical polarity and 1 magnet with horizontal polarity (the magnet with vertical polarity will be hereinafter referred to as the large magnet 12, and the magnet with horizontal polarity will be hereinafter referred to as the small magnet 11). The magnetic component 1 requires the small magnet 11 to be in the middle and the large magnets 12 to be combined on both sides. According to production requirements, the magnetic component 1 and the iron part 2 need to be assembled together, and the shape of the iron part 2 needs to match that of the magnetic component 1. As Figure 2 shown, the cross-section of the iron part 2 is L-shaped, including a horizontal plate 21 and a vertical plate 22 that are perpendicular to each other. The assembly steps are as follows: place the combined magnetic component on the jig, use a dispensing machine to dispense glue on one side (hereinafter referred to as the front side) and the top surface of the magnetic component, so that both the front side and the top surface of the magnetic component are covered with a glue layer. Subsequently, perform the operation of placing the iron part, and fit the vertical plate and the horizontal plate of the iron part with the front side and the top surface of the magnetic component after dispensing glue respectively. Then, press the iron part to tightly press the iron part and the magnetic component together. The structure after pressing is as Figure 3 shown; finally, place the jig on the tray, and then put the tray into a tunnel furnace for high-temperature curing, thus completing all the assembly processes. Due to the special structure and small volume of the magnetic component (the length of the magnetic component is 4.1 - 4.6 mm, the height is 06 - 1.0 mm, and the width is 1.1 - 1.5 mm), and involving multiple processes, the above series of assembly processes have not been replaced by mechanical equipment for manual operation, resulting in low production efficiency and high labor costs. Summary of the Invention

[0003] The purpose of the present invention is to provide an assembly method and device for a Halbach magnetic component, which can automatically complete operations such as dispensing glue, placing the iron part, and pressure holding, improve production efficiency, and reduce labor costs.

[0004] To achieve the above purpose, the present invention provides an assembly method for a Halbach magnetic component, which is assembled using an assembly device, including a feeding component, a dispensing component, an iron part placing component, a pressure holding component, and a jig; The jig is used to load the magnetic component, and the dispensing component, the iron part placing component, and the pressure holding component are arranged above or on one side of the feeding component, and the feeding component transports the jig to the dispensing component, the iron part placing component, and the pressure holding component; The dispensing assembly includes a dispensing machine and a first flipping mechanism. The first flipping mechanism includes a flipping platform and a flipping driving device. A dispensing station is provided on the flipping platform. The dispensing station is docked with the feeding assembly. The flipping driving device is connected to the flipping platform to drive the flipping platform to flip, so that the top surface and the front surface of the magnetic component on the flipping platform are tilted upward. The dispensing machine is located above the dispensing station to dispense glue on the top surface and the front surface of the magnetic component; The iron part placing assembly includes an iron part placing station, an iron part picking and placing mechanism, and an iron part loading tray. The iron part placing station is docked with the feeding assembly. The iron part loading tray is located on one side of the iron part placing station. The iron part picking and placing mechanism is located above the iron part picking and placing mechanism and the iron part loading tray to perform the operation of picking and placing iron parts; The pressure maintaining assembly includes a pressure maintaining station, an upper pressure maintaining push rod, and a side pressure maintaining push rod. The pressure maintaining station is docked with the feeding assembly. The upper pressure maintaining push rod is located above the pressure maintaining station. The side pressure maintaining push rod is located on one side of the pressure maintaining station; The assembling method includes the following steps: S1. Place the assembled magnetic component flat on the fixture, and then place the fixture into the feeding assembly. The feeding assembly transports the fixture to the dispensing station on the flipping platform; S2. The flipping driving device drives the flipping platform to flip by 40° - 50° to be inclined, so that the top surface and the front surface of the magnetic component on the dispensing station are tilted upward. Then, the dispensing machine dispenses glue on the top surface and the front surface of the magnetic component. After dispensing, the flipping platform flips back to its original position; S3. The feeding assembly transports the fixture after dispensing to the iron part placing station. Then, the iron part picking and placing mechanism grabs the iron part loaded on the iron part loading tray and places the iron part on the magnetic component at the iron part placing station, so that the horizontal plate and the vertical plate of the iron part are respectively attached to the top surface and the front surface of the magnetic component; S4. After the iron part is placed, the feeding assembly transports the fixture to the pressure maintaining station. Then, the upper pressure maintaining push rod and the side pressure maintaining push rod are started simultaneously to respectively squeeze the top surface and the front surface of the magnetic component, and the pressure maintaining of the magnetic component is completed.

[0005] Further, in step S2, the dispensing machine includes a three-axis robotic arm and a nozzle for dispensing glue. The dispensing machine is arranged on one side of the feeding assembly. The nozzle is arranged on the three-axis robotic arm; the number of nozzles is one, and the three-axis robotic arm drives the nozzle to dispense glue on the top surface and the front surface of the magnetic component in sequence; or the number of nozzles is multiple, and the multiple nozzles are arranged in two rows. The two rows of nozzles respectively correspond to the dispensing positions on the top surface and the front surface of the flipped magnetic component, and the three-axis robotic arm drives the two rows of nozzles to dispense glue on the top surface and the front surface of the magnetic component simultaneously.

[0006] Further, in step S1, a plurality of fixture acupoints arranged side by side left and right are provided at the top of the rear side wall of the fixture, and the magnetic component is placed flat on the fixture acupoints; in step S2, the dispensing station runs through the flipping platform left and right, and front side walls and rear side walls are provided on the front and rear sides of the dispensing station. When the fixture is located on the dispensing station, the fixture acupoints are higher than the rear side wall of the flipping platform, so that the top surface and the front surface of the magnetic component are exposed; the first flipping mechanism further includes a first pivot seat and a second pivot seat arranged side by side front and rear. The middle part of the flipping platform is rotatably arranged on the second pivot seat. The flipping driving device is a telescopic rod. One end of the telescopic rod is rotatably arranged on the first pivot seat, and the other end is pivotally connected to the front part of the flipping platform. Thus, before dispensing, while one end of the telescopic rod stretches, it drives the front part of the flipping platform to turn downward, then the rear part of the flipping platform turns upward, and further the magnetic component is flipped so that its top surface and front surface are tilted upward. The flipping angle of the flipping platform is 45°.

[0007] Further, in step S2, the first flipping mechanism further includes a positioning plate. The positioning plate is arranged to move back and forth at the rear side of the flipping platform. A positioning opening is provided on the front side of the positioning plate. Thus, before the flipping platform flips, the positioning plate moves forward to make the fixture on the dispensing station snap into the positioning opening, so as to position the front-back position and the left-right position of the fixture. After positioning, the positioning plate retreats, and then the flipping platform flips, and then dispensing is carried out.

[0008] Further, the feeding assembly includes a feeding cylinder, a first track and a second track arranged in a straight line. The second track is located on the right side of the first track. The feeding cylinder is located at the feeding port of the first track, and the piston rod of the feeding cylinder is connected to a push plate for pushing against the fixture. The flipping platform is located between the first track and the second track. The two ends of the dispensing station are respectively docked with the discharging port of the first track and the feeding port of the second track; thus, in step S1, a plurality of fixtures are sequentially placed at the feeding port of the first track, and the push plate of the feeding cylinder sequentially pushes the fixtures at the feeding port to move rightward, and further makes the plurality of fixtures move side by side rightward. After the fixture moves to the dispensing station, the feeding cylinder stops feeding; in step S2, after dispensing, the flipping platform flips back to the horizontal state, and then the feeding cylinder starts again to transport the fixture to the second track.

[0009] Further, in step S2, the dispensing machine further includes a base which is slidably arranged back and forth below the first track and the second track. A three-axis robotic arm is mounted on the base, and the first flipping mechanism is arranged on the base. Horizontal rollers are provided on the left and right sides of the flipping platform, and the edges of the rollers protrude outward from the left and right sides of the flipping platform. After the fixture moves to the dispensing station, the base drives the first flipping mechanism to move backward, and the two rollers on the flipping platform push aside the fixtures on the left and right sides of the dispensing station. Then, the fixture is positioned and the flipping platform is flipped. Then, the three-axis robotic arm drives the nozzle to dispense glue on the top and front surfaces of the magnetic component. After dispensing, the base drives the first flipping mechanism to reset, and the flipping platform rotates and resets again.

[0010] Further, the feeding component further includes a conveyor belt which is located on the right side of the second track, and the iron part placing component and the pressure maintaining component are located on one side of the conveyor belt. The assembling device further includes a glue inspection component which includes a camera, a second flipping mechanism and a prompting mechanism. The structure of the second flipping mechanism is the same as that of the first flipping mechanism, except that the working station on the flipping platform of the second flipping mechanism is a glue inspection station, and a cylinder is arranged below the second flipping mechanism to drive it to move back and forth. The second flipping mechanism is located between the second track and the conveyor belt, and the two ends of the glue inspection station are respectively connected to the discharge port of the second track and the feeding port of the conveyor belt. The camera is arranged above the glue inspection station, and the prompting mechanism is signal-connected to the camera. Thus, in step S2, after the glue dispensing is completed and the flipping platform rotates and resets, the feeding component transports the fixture to the glue inspection station. Then, the second flipping mechanism flips, and the flipping angle is the same as that of the first flipping mechanism, so that the top and front surfaces of the magnetic component on the glue inspection station are tilted upward. The camera takes pictures of the magnetic component to judge whether the glue dispensing of the magnetic component is qualified. If it is qualified, the second flipping mechanism resets and enters the next step. If it is unqualified, the prompting mechanism prompts the staff to remove the unqualified fixture.

[0011] Further, the feeding component further includes a first handling component and a second handling component. The first handling component and the second handling component are respectively located on one side of the iron part placing component and the pressure maintaining component. The first handling component includes a double-axis robotic arm and a jaw cylinder. The double-axis robotic arm is mounted on the conveyor belt, and the jaw cylinder is arranged on the double-axis robotic arm and aligned with the iron part placing station. Thus, in step S3, after the feeding component transports the fixture to the conveyor belt, the double-axis robotic arm drives the jaw cylinder to grab the fixture on the conveyor belt to the iron part placing station. After the iron part is placed, the first handling component transports the fixture back to the conveyor belt. The structure of the second handling component is the same as that of the first handling component, and the cylinder jaw of the second handling component is aligned with the pressure maintaining station. Then, in step S4, the second handling component transports the fixture on the conveyor belt to the pressure maintaining station and transports the pressure-maintained fixture back to the conveyor belt.

[0012] Further, the assembly device further includes a tray located on one side of the conveyor belt. The feeding component further includes a third handling component, whose structure is the same as that of the first handling component, and the dual-axis robotic arm of the third handling component is erected above the conveyor belt and the tray. Thus, the assembly method further includes the following steps: S5. The third handling component sequentially transports the multiple fixtures after pressure holding on the conveyor belt to the tray until the tray is full, and then the worker sends the tray full of fixtures into a tunnel furnace for high-temperature curing.

[0013] The present invention also provides an assembly device for a Halbach magnetic component, including a feeding component, a dispensing component, an iron part placing component, a pressure holding component, and a fixture; The fixture is used for loading the magnetic component. The dispensing component, the iron part placing component, and the pressure holding component are arranged above or on one side of the feeding component, and the feeding component transports the fixture to the dispensing component, the iron part placing component, and the pressure holding component; The dispensing component includes a dispenser and a first flipping mechanism. The first flipping mechanism includes a flipping platform and a flipping driving device. A dispensing station is provided on the flipping platform. The dispensing station is docked with the feeding component. The flipping driving device is connected to the flipping platform to drive the flipping platform to flip, so that the top surface and the front surface of the magnetic component on the flipping platform are tilted upward. The dispenser is located above the dispensing station to dispense glue on the top surface and the front surface of the magnetic component; The iron part placing component includes an iron part placing station, an iron part picking and placing mechanism, and an iron part loading tray. The iron part placing station is docked with the feeding component. The iron part loading tray is located on one side of the iron part placing station. The iron part picking and placing mechanism is located above the iron part picking and placing mechanism and the iron part loading tray to perform the operation of picking and placing iron parts; The pressure holding component includes a pressure holding station, an upper pressure holding push rod, and a side pressure holding push rod. The pressure holding station is docked with the feeding component. The upper pressure holding push rod is located above the pressure holding station, and the side pressure holding push rod is located on one side of the pressure holding station.

[0014] After adopting the above scheme, the beneficial effects of the present invention are as follows: 1. The present invention uses mechanical equipment to automatically complete processes such as dispensing, placing iron parts, and pressure holding, realizing the automation of magnetic component assembly, reducing labor costs and burdens, and improving production efficiency.

[0015] 2. Since the dispensing machine can only dispense glue vertically downward, before dispensing glue, the present invention flips the fixture through the first flipping mechanism, so that the top surface and the front surface of the magnetic component are flipped to be inclined upward, enabling the dispensing machine to dispense glue on the top surface and the front surface of the magnetic component successively or simultaneously. During this dispensing process, the first flipping mechanism does not need to flip again. In the existing dispensing equipment, after dispensing glue on one side of the magnetic component, the dispensing machine moves upward, and then a flipping device is used to drive the magnetic component to flip to the other side facing upward, and then glue is dispensed. Or after dispensing glue on one side, the dispensing machine is driven to flip by an angle to dispense glue on the other side. The existing dispensing process cannot achieve continuous dispensing. Moreover, since the shapes and sizes of the two dispensing surfaces are different, the dispensing positions are also different, and the movement parameters of the dispensing machine need to be adjusted frequently. However, the present invention can continuously and uninterruptedly complete the dispensing of the top surface and the front surface of the magnetic component, and can also simultaneously complete the dispensing of the top surface and the front surface of the magnetic component, which can improve the efficiency of the dispensing process. And the dispensing positions are fixed after the top surface and the front surface of the magnetic component are flipped to be inclined upward, and there is no need to frequently adjust the position of the dispensing machine, and the dispensing operation is simpler and more convenient.

[0016] 3. The present invention makes the top surface and the front surface of the magnetic component both inclined upward through the first flipping mechanism. By setting two rows of nozzles, glue can be dispensed on the two surfaces of the magnetic component simultaneously, and double-sided dispensing coating can be completed in a single operation, reducing the repeated positioning time by 50% and greatly improving the production efficiency.

[0017] 4. The first flipping mechanism of the present invention is also provided with a positioning plate, which can position the front-back position and left-right position of the fixture on the dispensing station, ensure that the dispensing position is fixed each time, improve the dispensing accuracy, and moreover, the present application is also provided with a glue inspection component to check whether the dispensing is qualified, improving the yield rate.

[0018] 5. The present invention adopts a multi-station parallel setting, that is, the dispensing component, the iron part placing component, and the pressure maintaining component operate in parallel, further improving the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0021] The following describes the present invention in detail with reference to the accompanying drawings and specific embodiments.

[0022] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "middle", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0023] As Figures 1-3 shown, the present invention needs to assemble the magnetic component 1 with the structure as Figure 1 shown and the iron part 2 with the structure as Figure 2 shown together. The assembled structure is as Figure 3 shown. The magnetic component 1 is composed of a small magnet 11 and two large magnets 12. The assembled magnetic component 1 is not a regular cuboid structure, but a special-shaped structure with an obtuse angle distribution between the two large magnets 12. The structure of the iron part 2 is matched with the shape of the magnetic component 1. The horizontal plate 21 and the vertical plate 22 of the iron part 2 need to be respectively attached to the top surface and the front surface of the magnetic component 1. Therefore, glue needs to be dispensed on the top surface and the front surface of the magnetic component 1.Figure 1 The shaded dots in the figure are the glue dots after dispensing. After dispensing, the iron piece 2 is placed on the magnetic assembly 1, and then the top and front surfaces of the magnetic assembly 1 are pressed to complete the assembly of the magnetic assembly 1 and the iron piece 2. Due to the special structure and small size of the magnetic assembly 1 (the length of the magnetic assembly 1 is only 4.1-4.6mm, the height is only 0.6-1.0mm, and the width is only 1.1-1.5mm), the traditional assembly process is still manually operated. In order to improve production efficiency and reduce labor costs, the present invention provides a Halbach magnetic assembly assembly method and equipment.

[0024] like Figures 4-17 As shown, the assembly equipment includes a machine 4, a fixture 3 and a feeding component 5, a glue dispensing component 6, a glue inspection component 7, an iron placing component 8, and a pressure maintaining component 9 arranged on the machine 4, and a PLC controller (not shown in the figure) for controlling the operation of each component. The glue dispensing component 6, the glue inspection component 7, the iron placing component 8, and the pressure maintaining component 9 are located above or on one side of the feeding component 5. The fixture 3 is provided with a plurality of fixture points 31 for loading the magnetic component 1. The feeding component 5 is used to transport the fixture 3 to the workstations of each component.

[0025] Key References Figures 6-7 The feeding assembly 5 includes a feeding cylinder 51, a first track 52, a second track 53 and a conveyor belt 54. The first track 52, the second track 53 and the conveyor belt 54 are arranged along a straight line from left to right, and the left ends are the feed port and the right ends are the discharge port. The feeding cylinder 51 is arranged at the feed port of the first track 52, and can be located above the feed port of the first track 52. The piston rod of the feeding cylinder 51 is connected to a push plate 511. The bottom of the push plate 511 is located in the first track 52 to push the fixture 3 to move. A sensor for sensing the fixture 3 (not shown in the figure) is provided at the feed port of the first track 52. The sensor is connected to the signal of the feeding cylinder 51. The sensor can be a fiber optic sensor. After multiple jigs 3 are sequentially placed into the feeding port of the first track 52, specifically into the right side of the push plate 511, the sensor receives a signal to prompt the feeding cylinder 51, and the piston rod of the feeding cylinder 51 begins to extend and retract to push the jigs 3 sequentially placed to the right, so that the multiple jigs 3 move side by side to the right, that is, the latter jig 3 will push the former jig 3 to move, and when the jig 3 moves to the conveyor belt 54, the conveyor belt 54 conveys the jig 3.

[0026] Key References Figures 7-12, the dispensing assembly 6 includes a dispenser 61 and a first flipping mechanism 62. The dispenser 61 includes a three-axis robotic arm 611, a base 612, and a nozzle 613 for dispensing. The base 612 is slidably arranged on the machine table 4 in the front-back direction and is located below the first track 52 and the second track 53. The three-axis robotic arm 611 is mounted on the base 612, and the nozzle 613 is arranged on the three-axis robotic arm 611. The three-axis robotic arm 611 drives the nozzle 613 to move up and down, left and right, and front and back to dispense glue on the magnetic assembly 1.

[0027] The first flipping mechanism 62 is arranged on the base 612 and is located between the first track 52 and the second track 53. The first flipping mechanism 62 includes a flipping platform 621 and a flipping driving device 622. A dispensing station 63 is provided on the flipping platform 621. The dispensing station 63 is docked with the feeding assembly 5. Specifically, the dispensing station 63 penetrates the flipping platform 621 in the left-right direction, and the left and right ends of the dispensing station 63 are respectively docked with the discharge port of the first track 52 and the feed port of the second track 53. Thus, the feeding cylinder 51 can push the fixture 3 onto the dispensing station 63. The flipping driving device 622 is connected to the flipping platform 621 to drive the flipping platform 621 to flip, so that the top surface and the front surface of the magnetic assembly 1 on the flipping platform 621 are tilted upward. As Figure 12 shown, the nozzle 613 dispenses glue vertically downward. After the magnetoresistive element is flipped so that its top surface and front surface are tilted upward, the nozzle 613 can dispense glue on both of these two surfaces. The dispensing direction is as shown by the arrows in Figure 12 . The nozzle 613 can complete the dispensing of the two surfaces as long as it moves up and down and horizontally.

[0028] Specifically, the number of the nozzles 613 can be one or more. If there is one nozzle 613, it sequentially dispenses glue on the top surface and the front surface of the magnetic assembly 1. If the number of the nozzles 613 is more than one, multiple nozzles 613 can be arranged in two rows. Taking Figure 7 as a reference, if the fixture 3 is placed so that the front surface of the magnetic assembly 1 faces backward, multiple nozzles 613 can be arranged in two parallel rows front and back. The two rows of nozzles 613 respectively correspond to the dispensing positions on the top surface and the front surface of the flipped magnetic assembly 1. Driven by the three-axis robotic arm 611, the two rows of nozzles 613 can simultaneously dispense glue on the top surface and the front surface of the magnetic assembly 1. The number of nozzles 613 in each row can be one or more. The number of nozzles 613 is preferably corresponding to the required glue dots. For example, Figure 1As shown, seven dispensing positions are required on each face of the magnetic component 1. Therefore, the number of nozzles 613 in each row is seven. After the three-axis robotic arm 611 drives the two rows of nozzles 613 to move to correspond to the dispensing positions, it then drives the nozzles 613 to move downward to complete the dispensing of the two faces of one magnetic component 1. Double-sided dispensing coating can be completed in a single operation, greatly improving production efficiency. In addition, multiple nozzles 613 can be arranged in a row, and one row of nozzles 613 can complete the dispensing of one face at a time.

[0029] If the existing technology is used to dispense the magnetic component 1, generally there are two methods. One is to keep the magnetic component 1 horizontally placed, and the dispenser vertically downward dispenses the top face of the magnetic component 1. Then the nozzle of the dispenser moves upward, and after the magnetic component 1 is flipped 90° by a flipping device, the other face is dispensed. The other is to keep the magnetic component 1 stationary. After the dispenser finishes dispensing one face, the nozzle of the dispenser changes the angle to dispense the other face. In both of these methods during dispensing, the dispenser cannot continuously complete the dispensing. After dispensing one face, the fixture 3 or the nozzle needs to be flipped, and the dispensing efficiency is low. Moreover, since the shapes and sizes of the two dispensing faces are different, the dispensing positions are also different. After dispensing one face, it is necessary to adjust the moving parameters of the dispenser, with frequent adjustments, complex operations and time-consuming. However, the present invention can continuously and uninterruptedly or simultaneously complete the dispensing of the two faces of the magnetic component 1, with high dispensing efficiency. And after the magnetic component 1 is flipped, the dispensing position is fixed, and there is no need to frequently adjust the position of the dispenser nozzle, and the dispensing operation is simpler and more convenient.

[0030] It should be noted that after multiple debuggings, the flipping angle of the flipping platform 621 is 40° - 50°. If it exceeds this angle range, there will be situations such as dispensing position deviation and uneven spraying. The best angle is 45°. At the position of flipping 45°, the tilting angles of the top face and the front face of the magnetic component 1 are the same, which can ensure the same dispensing thickness and uniformity of the two faces and improve the dispensing accuracy.

[0031] Furthermore, a plurality of fixture acupoints 31 arranged side by side left and right are provided at the top of the rear side wall of the fixture 3. The magnetic component 1 is placed flat on the fixture acupoints 31, and the top face and the front face of the magnetic component 1 are exposed. The front side wall 6211 and the rear side wall 6212 are provided on the front and rear sides of the dispensing station 63. When the fixture 3 is located at the dispensing station 63, the fixture acupoints 31 are higher than the rear side wall 6212 of the flipping platform 621, so that the top face and the front face of the flipped magnetic component 1 are also exposed and can be dispensed. After the dispenser 61 finishes dispensing one magnetic component 1, it then moves above the next magnetic component 1 for dispensing. After all the magnetic components 1 on all the fixture acupoints 31 are dispensed, the flipping platform 621 resets for the next round of dispensing.

[0032] The first flipping mechanism 62 further includes a first pivot seat 623, a second pivot seat 624, a bottom plate 625 and a positioning plate 626. The bottom plate 625 is disposed on the base 612. The first pivot seat 623 and the second pivot seat 624 are arranged side by side front and back on the bottom plate 625. The middle part of the bottom surface of the flipping platform 621 is rotatably disposed on the second pivot seat 624. The flipping drive device 622 is a telescopic rod, and the telescopic rod can be a hydraulic push rod or a pneumatic cylinder push rod. One end of the telescopic rod is rotatably disposed on the first pivot seat 623, and the other end is pivotally connected to the front part of the flipping platform 621. The middle part of the flipping platform 621 is rotatably disposed on the second pivot seat 624. The flipping drive device 622 is a telescopic rod. One end of the telescopic rod is rotatably disposed on the first pivot seat 623, and the other end is connected to the front side of the flipping platform 621. Thus, before dispensing, while one end of the telescopic rod stretches, it drives the front part of the flipping platform 621 to turn downward, then the rear part of the flipping platform 621 will turn upward, and further enables the magnetic component 1 to flip to its top surface and front surface to tilt upward.

[0033] Preferably, an L-shaped connecting rod 627 is further disposed between the telescopic rod and the flipping platform 621. The cross bar of the L-shaped connecting rod 627 is fixed to the bottom surface of the flipping platform 621. The vertical rod of the L-shaped connecting rod 627 is arranged downward, and the bottom end of the vertical rod is pivotally connected to the other end of the telescopic rod. The angle between the cross bar and the vertical rod of the L-shaped connecting rod 627 is slightly less than 90°, so that the vertical rod of the L-shaped connecting rod 627 tilts backward, and further enables the telescopic rod to stretch and push the front side of the flipping platform 621 to turn downward. In addition to the telescopic rod, the flipping drive mechanism can also be a motor, and the motor shaft directly or indirectly connected to the flipping platform 621 can drive the flipping platform 621 to rotate.

[0034] The positioning plate 626 is disposed at the rear side of the flipping platform 621. The positioning plate 626 is horizontally arranged. A cylinder is fixed to the bottom of the positioning plate 626 to push the positioning plate 626 to move back and forth. A C-shaped positioning opening 6261 is provided on the front side of the positioning plate 626. The length of the jig 3 is greater than the length of the dispensing station 63. Before the flipping platform 621 flips, the positioning plate 626 moves forward to make the jig 3 on the dispensing station 63 snap into the positioning opening 6261. The left and right end faces of the positioning opening 6261 can position the left and right positions of the jig 3. A positioning protrusion 6262 is further provided in the positioning opening 6261. The positioning protrusion 6262 abuts against the rear side of the jig 3 to position the front and back positions of the jig 3. By the positioning of the positioning plate 626, the dispensing position is ensured to be fixed each time, improving the dispensing accuracy.

[0035] As a preferred embodiment, a first limiting plate 628 and a second limiting plate 629 are provided below the flipping platform 621. The top of the first limiting plate 628 is provided with an inclined plane, and it is located below the front part of the flipping platform 621. After the flipping platform 621 flips, its bottom surface abuts against the inclined plane of the first limiting plate 628, thereby preventing the flipping platform 621 from further flipping, so as to position the flipping platform 621 at an inclined position of about 45° of flipping. The top of the second limiting plate 629 is a flat surface, and it is located below the rear part of the flipping platform 621, and can abut against the rear part of the flipping platform 621 to limit the flipping platform 621 in the horizontal position.

[0036] Furthermore, horizontal rollers 6213 are provided on the left and right sides of the flipping platform 621. The edges of the rollers 6213 protrude outwards from the left and right sides of the flipping platform 621. The rollers 6213 can be specifically arranged on the front side wall 6211 of the dispensing station 63. When the jig 3 moves to the dispensing station 63, the base 612 drives the first flipping mechanism 62 to move backward. During the movement, the two rollers 6213 on the flipping platform 621 can push the jigs 3 on the left and right sides of the dispensing station 63 aside to prevent the jigs 3 on the left and right sides from being stuck and adhered to the jig 3 on the dispensing station 63, which affects the rotation of the flipping platform 621. After the base 612 drives the first flipping mechanism 62 to move backward, the positioning and flipping operations are performed.

[0037] Focus on referring to Figure 13, the glue inspection assembly 7 includes a camera 71, a second flipping mechanism 72 and a prompting mechanism 73. The second flipping mechanism 72 has the same structure as the first flipping mechanism 62. The difference is that the working station on the flipping platform 621 of the second flipping mechanism 72 is a glue inspection station 74. The second flipping mechanism 72 is located between the second track 53 and the conveyor belt 54. The two ends of the glue inspection station 74 are respectively docked with the discharge port of the second track 53 and the feed port of the conveyor belt 54. A cylinder is provided at the bottom of the second flipping mechanism 72, and the second flipping mechanism 72 is driven by this cylinder to move back and forth. The camera 71 is preferably a CCD camera 71, and the camera 71 is arranged above the glue inspection station 74. The prompting mechanism 73 is signal-connected to the camera 71, that is, both are signal-connected to the PLC controller. After the glue dispensing is completed and the flipping platform 621 rotates and resets, the feeding assembly 5 transports the jig 3 to the glue inspection station 74. Then, the second flipping mechanism 72 performs the same action as the first flipping mechanism 62, making the top surface and the front surface of the magnetic component 1 on the glue inspection station 74 tilt upward. The camera 71 takes pictures of the magnetic component 1 to judge whether the glue dispensing of the magnetic component 1 is qualified. If it is qualified, the second flipping mechanism 72 resets and enters the next step. If it is unqualified, the prompting mechanism 73 prompts the staff to remove the unqualified jig 3. The prompting mechanism 73 can be an intelligent display screen. The camera 71 can send the photographing result to the intelligent display screen, and it is judged by the operator whether the glue dispensing is qualified. It can also be judged by the PLC controller whether it is qualified. If it is unqualified, the intelligent display screen can issue a voice prompt, or it can also display pictures and texts on the screen to prompt.

[0038] Focus on Figures 14-15 , the iron part placing assembly 8 includes an iron part placing station 81, an iron part picking and placing mechanism 82, and an iron part loading tray 83. The iron part placing station 81 is docked with the feeding assembly 5. The iron part loading tray 83 is a vibrating loading tray mechanism, which can automatically load the iron parts 2. The iron part loading tray 83 is located on one side of the iron part placing station 81. The iron part picking and placing mechanism 82 is located above the iron part placing station 81 and the iron part loading tray 83 to perform the operation of picking and placing the iron parts 2.

[0039] Specifically, the iron part placement station 81 and the iron part loading tray 83 are located at the rear side of the conveyor belt 54. The iron part picking and placing mechanism 82 includes a driving module 821 and an iron part gripping manipulator 822. The driving module 821 is erected above the iron part placement station 81 and the iron part loading tray 83. The iron part gripping manipulator 822 is arranged on the driving module 821. The driving module 821 can be a three-axis robotic arm or a two-axis robotic arm, which can drive the iron part gripping manipulator 822 to move up and down and horizontally, so as to move the iron part 2 on the iron part loading tray 83 to the magnetic component 1 at the iron part placement station 81. The iron part gripping manipulator 822 includes a gripping rod that can be telescoped up and down. A magnet is provided at the bottom of the gripping rod. The iron part 2 can be adsorbed by the magnet to grip the iron part 2. When the gripping rod drives the magnet to retract into the interior of the gripping rod, the magnet will be separated from the iron part 2, thus putting down the iron part 2.

[0040] Furthermore, the feeding assembly 5 further includes a first handling assembly 55 and a second handling assembly 56. The first handling assembly 55 and the second handling assembly 56 are respectively located at the front side of the iron part placing assembly 8 and the pressure maintaining assembly 9. The first handling assembly 55 includes a two-axis robotic arm 551 and a jaw cylinder 552. The two-axis robotic arm 551 is erected on the conveyor belt 54. The jaw cylinder 552 is arranged on the two-axis robotic arm 551 and is aligned with the iron part placement station 81. The two-axis robotic arm 551 can drive the jaw cylinder 552 to move up and down and back and forth. The first handling assembly 55 further includes a moving cylinder 553 and a clamping cylinder 554. The moving cylinder 553 is located at the front side of the iron part picking and placing mechanism 82. The clamping cylinder 554 is arranged on the moving cylinder 553. The iron part placement station 81 for clamping the fixture 3 is arranged on the clamping cylinder 554. After the feeding assembly 5 transports the fixture 3 to the conveyor belt 54, the two-axis robotic arm 551 drives the jaw cylinder 552 to grip the fixture 3 on the conveyor belt 54. Then the moving cylinder 553 pushes the clamping cylinder 554 forward. The jaw cylinder 552 moves back and forth to place the iron part 2 on the iron part placement station 81. The clamping cylinder 554 clamps the iron part 2. Then the moving cylinder 553 resets. The iron part picking and placing mechanism 82 performs the iron part 2 placement operation. After the iron part 2 placement is completed, the first handling assembly 55 transports the fixture 3 back to the conveyor belt 54.

[0041] As a preferred embodiment, a blocking cylinder 555 is provided on the conveyor belt 54. After the fixture 3 moves below the jaw cylinder 552, the blocking cylinder 555 is pushed out to block the fixture 3, and the fixture 3 stops moving, which is convenient for the jaw cylinder 552 to clamp the fixture 3. After the blocking cylinder 555 extends, the conveyor belt 54 pauses the conveyance. After the fixture 3 with the iron part 2 placed is transported back to the conveyor belt 54, the blocking cylinder 555 resets, and the conveyor belt 54 continues to convey.

[0042] Focus on Figures 16-17, specifically, the structure of the second handling component 56 is the same as that of the first handling component 55, except that the cylinder gripper of the second handling component 56 is aligned with the pressure-holding station 91, and the clamping cylinder 554 of the second handling component 56 is for the pressure-holding station 91 of the clamping fixture 3. The second handling component 56 transports the fixture 3 on the conveyor belt 54 to the pressure-holding station 91 and transports the fixture 3 after pressure-holding back to the conveyor belt 54.

[0043] The pressure-holding component 9 includes a pressure-holding station 91, an upper pressure-holding push rod 92, and a side pressure-holding push rod 93. The upper pressure-holding push rod 92 is located above the pressure-holding station 91, and the side pressure-holding push rod 93 is located on one side of the pressure-holding station 91. After the fixture 3 moves to the pressure-holding station 91, the clamping cylinder 554 of the second handling component 56 clamps the fixture 3, and the moving cylinder 553 retracts to be close to the upper pressure-holding push rod 92 and the side pressure-holding push rod 93, so that the upper pressure-holding push rod 92 and the magnetic component 1 are vertically aligned. Then, the upper pressure-holding push rod 92 and the side pressure-holding push rod 93 both push out to respectively squeeze the top surface and the front surface of the magnetic component 1, so that the iron part 2 is pressed against the magnetic component 1 to achieve the pressure-holding effect.

[0044] Preferably, both the upper pressure-holding push rod 92 and the side pressure-holding push rod 93 are pushed by threaded cylinders, so that the thrust of the push rods can be maintained in a stable state for a long time to ensure stable pressure-holding.

[0045] The assembly equipment further includes a tray 10. The tray 10 is located behind the conveyor belt 54, so that the iron part assembly 8, the pressure-holding component 9, and the tray 10 are arranged side by side from left to right; the feeding component 5 further includes a third handling component 57. The structure of the third handling component 57 is the same as that of the first handling component 55, except that there is no moving cylinder 553 and clamping cylinder 554, and the double-axis robotic arm 551 of the third handling component 57 is erected above the conveyor belt 54 and the tray 10, and can sequentially transport the pressure-held fixtures 3 on the conveyor belt 54 to the tray 10 until the tray 10 is full. Then, the operator sends the tray 10 full of fixtures 3 to the next process, that is, into a tunnel furnace for high-temperature curing.

[0046] In addition, fiber optic sensors are provided on the dispensing component 6, the glue inspection component 7, the iron part placing component 8, and the tray 10. After the fixture 3 moves to the dispensing station 63, the glue inspection station 74, the iron part placing station 81, and the tray 10, the corresponding fiber optic sensors obtain signals, so that the corresponding components start to perform operations.

[0047] Using the above assembly equipment to assemble the magnetic component and the iron part, the assembly method specifically includes the following steps: S1. Place the assembled magnetic component 1 flat on the fixture 3. Then, place multiple fixtures 3 at the feeding port of the first track 52 in sequence. The corresponding sensor obtains a signal, causing the feeding cylinder 51 to start working. The feeding cylinder 51 sequentially pushes multiple fixtures 3 to move rightward. After the fixture 3 is transported to the dispensing station 63 of the flipping platform 621, the feeding cylinder 51 stops working. S2. After the fixture 3 reaches the dispensing station 63, the corresponding sensor obtains a signal, causing the base 612 of the dispenser 61 to drive the first flipping mechanism 62 to move backward. The rollers 6213 on the flipping platform 621 push the fixtures 3 on both sides of the dispensing station 63 aside. Then, the positioning plate 626 moves forward to position the left-right and front-back positions of the fixture 3 on the dispensing station 63. Then, the flipping drive device 622 drives the flipping platform 621 to flip 40° - 50° to an inclined state, preferably 45°, so that the top surface and the front surface of the magnetic component 1 on the dispensing station 63 are inclined upward. Then, the nozzle 613 of the dispenser 61 dispenses glue on the top surface and the front surface of the magnetic component 1 through the three-axis robotic arm 611. After dispensing, the flipping platform 621 flips back to the original position, and the base 612 drives the first flipping mechanism 62 to move forward to the original position. The feeding cylinder 51 continues to work to transport the dispensed fixture 3 to the glue inspection station 74. The corresponding sensor obtains a signal, and the feeding cylinder 51 pauses. The second flipping mechanism 72 repeats the action of the first flipping mechanism 62 to flip the fixture 3 so that the top surface and the front surface of the magnetic component 1 on the glue inspection station 74 are inclined upward. Then, the camera 71 takes a picture of the magnetic component 1 to determine whether the glue dispensing of the magnetic component 1 is qualified. If it is qualified, the second flipping mechanism 72 resets and enters the next step. If it is not qualified, the prompting mechanism 73 prompts the staff to remove the unqualified fixture 3, and the second flipping mechanism 72 resets to inspect the next fixture. S3. The feeding cylinder 51 continues to feed, transporting the fixture 3 to the conveyor belt 54. The conveyor belt 54 transports the fixture 3 under the clamping cylinder 552 of the first handling component 55. The blocking cylinder 555 extends to block the fixture 3, and the conveyor belt 54 pauses. The clamping cylinder 552 grabs the fixture 3. At the same time, the moving cylinder 553 at the iron part placement station 81 drives the clamping cylinder 554 to extend forward. The clamping cylinder 552 places the fixture 3 on the iron part placement station 81 of the clamping cylinder 554. The clamping cylinder 554 clamps the fixture 3. Then, the moving cylinder 553 resets. The iron part picking and placing mechanism 82 grabs the iron part 2 loaded from the iron part loading tray 83 and places the iron part 2 on the magnetic component 1 at the iron part placement station 81, so that the horizontal plate 21 and the vertical plate 22 of the iron part 2 are respectively attached to the top surface and the front surface of the magnetic component 1. After the iron part 2 is placed, the first handling component 55 transports the fixture 3 back to the conveyor belt 54, and the blocking cylinder 555 retracts. S4. The conveyor belt 54 continues to feed and conveys the jig 3 to the second handling component 56. The second handling component 56 conveys the jig 3 to the pressure-holding station 91. The handling action is the same as that of the first handling component 55. Then, the upper pressure-holding push rod 92 and the side pressure-holding push rod 93 are simultaneously pushed out to respectively squeeze the top surface and the front surface of the magnetic component 1, completing the pressure-holding of the magnetic component 1. Then, the upper pressure-holding push rod 92 and the side pressure-holding push rod 93 are reset, and the second handling component 56 conveys the jig 3 back to the conveyor belt 54.

[0048] S5. The conveyor belt 54 continues to convey the jig 3 to the third handling component 57. The cylinder gripper of the third handling component 57 sequentially conveys the pressure-held jigs 3 to the tray 10 until the tray 10 is full. The sensor gets the signal and gives a prompt. Then, the worker sends the tray 10 full of jigs 3 into the tunnel furnace for high-temperature curing.

[0049] The above are only the preferred embodiments of the present invention and do not limit the design of this case. All equivalent changes made according to the key design of this case fall within the protection scope of this case.
