Description

Technical Field

[0001] The present invention relates to a magnet automatic filling device and method, belonging to the technical field of automation equipment. Background Art

[0002] At present, there are a wide variety of handheld electronic products on the market. For products that need to be frequently disassembled and assembled, if it can be ensured that the disassembly is easy and the installation is reliable, it has become an important design requirement. The usual disassembly structure is a snap structure. However, this structure is easy to assemble, relatively difficult to take out, and easy to damage the product. Although the method of screwing has high reliability, the disassembly is more difficult and is not suitable for components that need to be frequently disassembled. Therefore, generally, the magnet adsorption method is adopted to achieve this. This structure can be quickly installed, the disassembly is also very easy, and the cost is relatively not high.

[0003] However, the existing installation of magnets generally adopts manual picking and placing filling (that is, manual installation of magnets) or single-station filling method (that is, semi-automatic installation of magnets), and the operation efficiency is low.

[0004] Therefore, finding a magnet automatic filling device that can realize automatic magnet filling to improve the installation efficiency of magnets is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0013] Furthermore, the magnet automatic filling device further includes an equipment hood and a distance sensor capable of detecting whether a bracket is fixed to the bracket fixing block. The distance sensor is installed on the equipment hood, the equipment hood is installed on the equipment base, and light grids capable of detecting whether there are obstacles are respectively provided on the left and right sides of the equipment base.

[0014] According to an embodiment of the present invention, the second solution is provided as follows: a magnet automatic filling method, which performs magnet automatic filling based on the magnet automatic filling device described above.

[0015] Furthermore, the equipment base is divided into a feeding station, a magnet loading station, a pressing station, a gasket pasting station, and a blanking station in the order of magnet filling. The feeding station, the magnet loading station, the pressing station, the gasket pasting station, and the blanking station are evenly distributed around the circumference of the turntable, and the magnet feeding member reciprocates between the magnet taking position and the magnet sending position;

[0016] The method includes the following steps:

[0017] S1. Feeding: The rotary driving part drives the turntable to rotate, rotates the bracket fixing block on the turntable to the feeding station, fixes the bracket to the bracket fixing block, and judges whether the bracket has been loaded through the distance sensor installed at the top of the feeding station, and judges whether the operator's arm has completely withdrawn from the magnet automatic filling device through the light grids provided on the left and right sides of the equipment base. If the bracket has been loaded and the operator's arm has completely withdrawn from the magnet automatic filling device, then go to step S2;

[0018] While performing the above feeding, the preparation of the magnets is synchronously carried out, including: driving the magnet feeding member to the magnet taking position. At this time, the magnet storage through hole, the magnet passage through hole, and the magnet temporary storage hole are coaxial, and the lowermost magnet slides down into the magnet temporary storage hole from top to bottom, and then driving the magnet feeding member together with the magnet located in the magnet temporary storage hole to the magnet sending position;

[0019] S2. Upper magnet. The rotation drive unit drives the turntable to rotate, rotates the bracket that has completed loading to the upper magnet station, rotates the magnet filling arm to the upper part of the magnet temporarily placed in the magnet feeding hole of the magnet feeding member, then descends, adsorbs the magnet through the suction cup on the magnet filling arm, then ascends and rotates to the side opening of the bracket, and then descends to release the magnet onto the magnet filling counterbore of the bracket. After the magnet filling arm leaves the bracket, step S3 is entered;

[0020] S3. Pressing. The rotation drive unit drives the turntable to rotate, rotates the bracket that has completed upper magnet to the pressing station, rotates the magnet pressing arm to the side opening of the bracket, and then descends to press the magnet into the magnet filling counterbore of the bracket. The magnet pressing arm maintains the pressing state for a preset time. The magnet and the magnet filling counterbore of the bracket are in interference fit. After the magnet pressing arm leaves the bracket, step S4 is entered;

[0021] S4. Laminating the gasket. The rotation drive unit drives the turntable to rotate, rotates the bracket that has completed magnet pressing to the gasket laminating station, rotates the gasket laminating arm to the upper part of the gasket, then descends, adsorbs the gasket through the suction cup on the gasket laminating arm, then ascends and rotates to the side opening of the bracket, and then descends to laminate the gasket onto the magnet located in the magnet filling counterbore of the bracket; while laminating the gasket, the optical sensor is used to sense whether the gasket on the tape has been taken away. If the gasket has been taken away, the tape is driven by the take-up wheel to drive the next gasket to the position waiting to be taken;

[0022] S5. Unloading. The rotation drive unit drives the turntable to rotate, rotates the bracket with the magnet that has completed gasket laminating to the unloading station, rotates the bracket gripping arm to the upper part of the bracket, then descends, grips the bracket through the jaws on the bracket gripping arm, then ascends and rotates to the upper part of the unloading conveyor mechanism, and then descends to release the bracket onto the unloading conveyor mechanism to complete unloading.

[0023] Further, in step S1, judging whether the bracket has been loaded by the distance sensor installed at the top of the loading station includes: presetting a height change range value. If the distance change value detected by the distance sensor falls within the preset height change range value, it is determined that the bracket has been loaded.

[0024] Further, in step S1, it is determined whether the operator's arm has completely withdrawn from the magnet automatic filling device by means of the gratings arranged on the left and right sides of the device base, including: when the gratings on the left and right sides sense an obstacle, the device is in the standby state; when the gratings on the left and right sides do not sense an obstacle, it is considered that the operator's arm has completely withdrawn from the device, and the system gives a signal to trigger the rotation drive unit (i.e., the stepper motor) to rotate clockwise (it can also be counterclockwise, which can be set accordingly as needed), and send the bracket to the next working station.

[0025] Compared with the prior art, a magnet automatic filling device and method provided by the present application can fix the bracket on the bracket fixing block, drive the turntable to rotate through the rotation drive unit, so as to drive the bracket to move to the next working station after the assembly of the current working station is completed. The magnet filling arm can obtain magnets from the magnet storage and then place them into the magnet filling sink of the bracket fixed on the bracket fixing block to complete the filling and assembly of the magnets. The magnet pressing arm can press the magnets placed into the magnet filling sink of the bracket, so as to press the magnets into the magnet filling sink of the bracket, realizing the automatic filling of the magnets and improving the installation efficiency of the magnets.

[0048] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which this application can be implemented. Therefore, they have no substantive technical significance. Any structural modification, change in proportional relationship or adjustment of size should still fall within the scope of the technical content disclosed in this application without affecting the efficacy and purpose that can be achieved by this application.

[0049] According to an embodiment of the present invention, a first scheme is provided: an automatic magnet filling device, comprising an equipment base 1, a turntable 5, a rotation drive unit 16, a bracket fixing block 6 capable of fixing a bracket 14, a magnet storage 7 for storing magnets 15, a magnet filling arm 8 capable of rotating and lifting movements, and a magnet pressing arm 9 capable of rotating and lifting movements, wherein the turntable 5 is rotatably mounted on the equipment base 1, the rotation drive unit 16 is mounted on the equipment base 1 and connected to the turntable 5, the bracket fixing block 6 is fixed on the turntable 5, the magnet storage 7 and the magnet filling arm 8 are respectively mounted on the equipment base 1, the magnet filling arm 8 can obtain the magnet 15 from the magnet storage 7 and then place it into the magnet filling countersunk hole 142 of the bracket 14 fixed on the bracket fixing block 6, and the magnet pressing arm 9 is mounted on the equipment base 1, and the magnet pressing arm 9 can press the magnet 15 placed in the magnet filling countersunk hole 142 of the bracket 14.

[0050] In this technical solution, it should be noted that the bracket 14 can be fixed on the bracket fixing block 6, and the turntable 5 can be driven to rotate by the rotating drive unit 16, thereby driving the bracket 14 to move to the next station after completing the assembly of the current station. The magnet 15 can be obtained from the magnet storage 7 by the magnet filling arm 8 and then placed in the magnet filling countersunk hole 142 of the bracket 14 fixed on the bracket fixing block 6 to complete the filling and assembly of the magnet 15. The magnet 15 placed in the magnet filling countersunk hole 142 of the bracket 14 can be pressed by the magnet pressing arm 9, thereby pressing the magnet 15 into the magnet filling countersunk hole 142 of the bracket 14, thereby realizing automatic filling of the magnet 15 and improving the installation efficiency of the magnet 15.

[0051] It should be noted that the bracket 14 is a product that needs to be assembled with the magnet 15, and the purpose of the automatic magnet filling device is to automatically assemble the magnet 15 onto the bracket 14 to improve production efficiency.

[0052] It should be noted that the bracket fixing block 6 is a bracket fixing fixture, which has a bracket fixing hole on which the bracket 14 can be fixed. The bracket 14 can be placed on the bracket fixing hole, and the turntable 5 can drive the bracket 14 to rotate.

[0053] It should be noted that the rotation driving unit 16 is used to drive the turntable 5 to rotate. The rotation driving unit 16 can preferably be a motor, such as a stepping motor, but is not limited thereto.

[0054] It should be noted that the turntable 5 can be rotatably connected to the device base 1 via a rotating shaft.

[0055] It should be noted that the bracket 14 has a lateral opening 141 and a magnet-filled countersunk hole 142 .

[0056] It should be noted that after the magnet filling arm 8 fills the magnet 15 into the magnet filling countersunk hole 142 of the bracket 14, the magnet pressing arm 9 needs to press the magnet 15 thoroughly and completely into the magnet filling countersunk hole 142 so that the magnet 15 and the magnet filling countersunk hole 142 have an interference fit.

[0057] It should be noted that after the magnet pressing arm 9 presses the magnet 15 into the magnet filling countersunk hole 142, it can be maintained for a period of time, for example, 3 seconds before being reset. This can prevent the magnet 15 from loosening and falling, and can also prevent the magnet 15 from being pressed into place, thereby avoiding affecting the subsequent gasket 115.

[0058] To elaborate specifically, in an embodiment of the present invention, the automatic magnet filling device further includes a gasket fitting device, which includes a gasket feeder 11 and a gasket fitting arm 10 capable of rotating and lifting movements, wherein the gasket fitting arm 10 obtains a gasket 115 from the gasket feeder 11 and then fits it onto the magnet 15 placed in the magnet filling counterbore 142 of the bracket 14.

[0059] It should be noted that the gasket 115 can be transported by the gasket feeder 11, and the gasket 115 can be transported to the gasket taking position of the gasket fitting arm 10, and then the gasket 115 can be taken by the gasket fitting arm 10, and then fitted onto the magnet 15 that has been pressed.

[0060] It should be noted that attaching the gasket 115 to the magnet 15 can make the installation of the magnet 15 more reliable and prevent the magnet 15 from loosening and falling.

[0061] Specifically, in the embodiment of the present invention, the gasket feeder 11 includes a tape conveyor 112, a feeding wheel 111, a take-up wheel 113, a tape 114, and a gasket 115. Among them, the gasket 115 is arranged on the tape 114, and the tape 114 is tensioned on the tape conveyor 112, the feeding wheel 111, and the take-up wheel 113. The tape conveyor 112 includes a tape conveyor mounting bracket 1121, a tape conveyor slide 1122, an upper tensioning wheel 1123, and a lower tensioning wheel 1124. Among them, the tape conveyor slide 1122 is fixed on the tape conveyor mounting bracket 1121, and the tape conveyor mounting bracket 1121 is fixed on the equipment base 1. The upper tensioning wheel 1123 and the lower tensioning wheel 1124 are respectively installed on the tape conveyor mounting bracket 1121 through rotating shafts. The tape conveyor slide 1122 has an upper conveying plane and a lower conveying platform. The tape is tensioned on the feeding wheel 111, the upper tensioning wheel 1123, the upper conveying plane of the tape conveyor slide 1122, the lower conveying plane of the tape conveyor slide 1122, the lower tensioning wheel 1124, and the take-up wheel 113 in sequence along its conveying direction.

[0062] It should be noted that the take-up wheel 113 is a driving wheel, and the tape 114 can be driven forward by the take-up wheel 113, so as to convey the gasket 115 on the tape 114 forward and convey the gasket 115 to the gasket picking position of the gasket fitting arm 10.

[0063] It should be noted that the gasket 115 can be a mylar sheet. Attaching a mylar sheet to the magnet 15 can make the installation of the magnet 15 more reliable and prevent the magnet 15 from loosening and falling off.

[0064] It should be noted that the upper tensioning wheel 1123 can make the tape 114 enter the upper conveying plane of the tape conveyor slide 1122 horizontally, so that when the gasket 115 reaches the gasket picking position of the gasket fitting arm 10, it is in a horizontal state, which is beneficial to the gasket picking operation of the gasket fitting arm 10. The lower tensioning wheel 1124 can make the tape 114 enter the lower conveying plane of the tape conveyor slide 1122 horizontally to save the space below.

[0065] It should be noted that the tape conveyor slide 1122 can adopt an outer contour in the shape of a runway, but is not limited thereto.

[0066] It should be noted that the tape 114 is tensioned by the upper tensioning wheel 1123 and the lower tensioning wheel 1124, which is convenient for the tape 114 to be tightened and positioned. The feeding wheel 111 is a driven wheel, and the take-up wheel 113 is a driving wheel. When all the mylar sheets are attached, the tape 114 will be completely taken into the take-up wheel 113, which is convenient for replacing the tape 114. The movement of the tape 114 relies on the stepping motor on the feeding wheel 111 for precise position movement.

[0067] To explain specifically, in an embodiment of the present invention, a light sensor mounting groove 11221 is provided on the upper conveying plane of the material belt conveying slide 1122, and a light sensor 1125 is provided in the light sensor mounting groove 11221 for detecting whether there is a gasket 115 on the material belt 114. The material belt 114 is made of a transparent material that can transmit light, and the gasket 115 is made of an opaque material that can block light.

[0068] It should be noted that a light sensor 1125 is designed at the gasket taking position of the gasket fitting arm 10. This light sensor 1125 can judge the light changes. Among them, the material belt 114 is a transparent material and can pass light, while the Mylar sheet is a black material and can block light. When the first Mylar sheet moves to the top of the light sensor 1125, the light sensor 1125 detects an obvious light change. At this time, the light sensor 1125 sends a signal to the motor of the material receiving wheel 113, the material belt 114 stops moving, and triggers a signal to the gasket fitting arm 10 for absorption.

[0069] To explain in detail, in an embodiment of the present invention, the magnet filling arm 8 has a rotating and lifting body, the end of the rotating and lifting body is a Z-shaped or L-shaped arm end 81, and a suction cup 82 is installed on the arm end 81. The Z-shaped or L-shaped arm end is conducive to extending into the side opening 141 of the bracket 14, and the suction cup is used to facilitate the adsorption of the magnet 15.

[0070] To explain in detail, in an embodiment of the present invention, the magnet pressing arm 9 has a rotating and lifting body, the end of the rotating and lifting body is a Z-shaped or L-shaped arm end, and a suction cup is installed on the arm end. The Z-shaped or L-shaped arm end is conducive to extending into the side opening 141 of the bracket 14, and the suction cup is used to facilitate the adsorption of the magnet 15.

[0071] To explain in detail, in an embodiment of the present invention, the gasket fitting arm 10 has a rotating and lifting body, the end of the rotating and lifting body is a Z-shaped or L-shaped arm end, and a suction cup is installed on the arm end. The Z-shaped or L-shaped arm end is conducive to extending into the side opening 141 of the bracket 14, and the suction cup is used to facilitate the adsorption of the gasket 115.

[0072] It should be noted that the magnet filling arm 8, the magnet pressing arm 9 and the gasket fitting arm 10 can adopt the same structure.

[0073] It should be noted that the rotational movement of the magnet filling arm 8, the magnet pressing arm 9 and the gasket fitting arm 10 can be achieved by a motor.

[0074] It should be noted that the lifting movements of the magnet filling arm 8, the magnet pressing arm 9, and the gasket fitting arm 10 can be achieved by a cylinder or a motor driving a lead screw.

[0075] Specifically described, in the embodiment of the present invention, the magnet storage 7 includes a magnet storage base 71, a magnet storage bin 72, and a magnet feeding member 73. A magnet storage through hole 721 is provided in the magnet storage bin 72. The bottom of the magnet storage bin 72 is connected to the magnet storage base 71. A magnet passage through hole 712 and a sliding passage 711 are provided on the magnet storage base 71. The magnet passage through hole 712 is communicated with the sliding passage 711. The magnet feeding member 73 passes through the sliding passage 711 of the magnet storage base 71 and is slidably matched with the sliding passage 711. A magnet temporary storage hole 731 is provided on the magnet feeding member 73. When the magnet storage through hole 721, the magnet passage through hole 712, and the magnet temporary storage hole 731 are coaxial, the lowermost magnet 15 can slide down into the magnet temporary storage hole 731 from top to bottom.

[0076] It should be noted that multiple layers of magnets 15 can be stacked and stored in the magnet storage through hole 721 of the magnet storage bin 72. The magnet feeding member 73 can reciprocally translate along the sliding passage 711. When the magnet storage through hole 721, the magnet passage through hole 712, and the magnet temporary storage hole 731 are coaxial, the lowermost magnet 15 can slide down into the magnet temporary storage hole 731 from top to bottom, thereby realizing the taking of the magnet 15. After taking the magnet 15, the taken magnet 15 can be transported to the magnet feeding position by the magnet feeding member 73.

[0077] It should be noted that a cylinder can be used to drive the magnet feeding member 73 to reciprocally translate along the sliding passage 711, but it is not limited thereto. Other devices that can achieve translational drive, such as a linear motor, can also be used.

[0078] It should be noted that the magnet feeding member 73 can be a magnet feeding slide rail or a magnet feeding slide plate.

[0079] It should be noted that the magnet storage bin 72 can be cylindrical, and the magnet feeding member 73 can be plate-shaped.

[0080] To be specific, in an embodiment of the present invention, the bottom of the magnet storage bin 72 is rotatably connected to the magnet storage base 71, and two or more magnet storage through holes 721 are provided in the magnet storage bin 72. The axes of the magnet storage through holes 721, the magnet passage through holes 712 and the magnet temporary storage holes 731 are all perpendicular to the horizontal plane, and the magnet feeding member 73 is parallel to the horizontal plane. The gap between the top surface of the magnet feeding member 73 and the top surface of the sliding channel 711 is less than the thickness of the magnet 15, and the depth of the magnet temporary storage hole 731 is equal to the thickness of the magnet 15. The magnet storage bin 72 is a transparent magnet storage bin 72 on which the current amount of magnets can be checked.

[0081] It should be noted that multiple magnet storage holes 721 can be set in the magnet storage bin 72, and each magnet storage hole 721 is a bin body. This embodiment is described by taking four magnet storage holes 721 as an example, but is not limited to this, and the number can be adjusted as needed.

[0082] It should be noted that four magnet storage holes 721 are provided in the magnet storage bin 72, which can increase the storage capacity of the magnets 15 and reduce the time for downtime for loading. After the magnets 15 in one of the magnet storage holes 721 are taken out, the magnet storage bin 72 can be rotated 90 degrees to make the other magnet storage hole 721 of the magnet storage bin 72 coaxial with the magnet temporary storage hole 731, so that the magnets 15 in the magnet storage hole 721 can be taken out. By using four bins, enough magnets 15 can be placed according to production requirements to achieve automation.

[0083] It should be noted that the rotation of the magnet storage bin 72 can be driven by a motor.

[0084] 712 and the magnet temporary placement hole 731 are coaxial.

[0085] Specifically, in the embodiment of the present invention, the magnet automatic filling device further includes a blanking device, and the blanking device includes a bracket gripping arm 13 capable of rotating and lifting movements and a blanking conveyor belt mechanism 12. The bracket gripping arm 13 can grab the bracket 14 filled with magnets 15 from the turntable 5 and then transfer it to the blanking conveyor belt mechanism 12.

[0086] It should be noted that after the magnets are filled, the magnets are pressed, and the mylar sheets are pasted, the bracket 14 can be unloaded through the blanking device and conveyed to the next station through the blanking conveyor belt mechanism 12, providing a docking basis for the automated assembly of products.

[0087] It should be noted that the bracket gripping arm 13 has a rotating and lifting body, and a clamping jaw 131 is provided at the end of the rotating and lifting body. The bracket 14 can be clamped by the clamping jaw 131.

[0088] It should be noted that the rotational movement of the bracket gripping arm 13 can be realized by a motor.

[0089] It should be noted that the lifting movement of the bracket gripping arm 13 can be realized by a cylinder or a motor-driven lead screw.

[0090] Specifically, in the embodiment of the present invention, the magnet automatic filling device further includes an equipment hood 2 and a distance sensor 3 capable of detecting whether a bracket 14 is fixed to the bracket fixing block 6. The distance sensor 3 is installed on the equipment hood 2, the equipment hood 2 is installed on the equipment base 1, and grating sensors 4 capable of detecting whether there are obstacles are respectively provided on the left and right sides of the equipment base 1.

[0091] It should be noted that when the bracket 14 is placed in the bracket fixing fixture, the distance sensor 3 at the top of the equipment detects a change in distance, and this change value is preset in advance to determine whether the placed product (i.e., the bracket) is correct. When the correct product is placed, the system determines that the product is in place. However, since the operator's arm extends into the equipment hood 2 and is sensed by the grating sensors 4 on the left and right sides as an obstacle, the equipment is in a standby state at this time. When the operator's arm completely exits the equipment hood 2, the system gives a signal to trigger the stepping motor to rotate clockwise and send the bracket 14 to the next station.

[0092] It should be noted that the equipment hood 2 uses a transparent equipment hood, which is convenient for observing the assembly process of the magnets 15.

[0093] According to the implementation scheme of the present invention, the second scheme is provided as follows: a magnet automatic filling method for magnet automatic filling based on the magnet automatic filling device.

[0094] It should be noted that the above-mentioned magnet automatic filling device is used for magnet automatic filling.

[0095] Specifically, in the embodiment of the present invention, the equipment base 1 is divided into a feeding station 17, a magnet loading station 18, a pressing station 19, a gasket pasting station 20, and a discharging station 21 in the order of magnet filling. The feeding station 17, the magnet loading station 18, the pressing station 19, the gasket pasting station 20, and the discharging station 21 are evenly distributed along the circumferential direction of the turntable 5. Specifically: the feeding station 17, the magnet loading station 18, the pressing station 19, the gasket pasting station 20, and the discharging station 21 are arranged at intervals of 72 degrees along the circumferential direction of the turntable 5, and the angle by which the rotary drive unit 16 drives the turntable 5 to rotate is also 72 degrees, that is, each rotation of 72 degrees is a production cycle.

[0096] The magnet feeding member 73 reciprocates between the magnet taking position and the magnet feeding position. When the magnet passing through hole 712 and the magnet temporary storage hole 731 are coaxial, the magnet feeding member 73 reaches the magnet taking position. When the axis of the magnet temporary storage hole 731 intersects the trajectory circle of the suction cup of the magnet filling arm 8, the magnet feeding member 73 reaches the magnet feeding position.

[0097] The method includes the following steps:

[0098] S1. Feeding, that is, placing the bracket 14 on the bracket fixing block 6 of the turntable 5 and fixing it. The rotary drive unit 16 drives the turntable 5 to rotate, rotates the bracket fixing block 6 on the turntable 5 to the feeding station 17, fixes the bracket 14 to the bracket fixing block 6, and determines whether the bracket 14 has been loaded through the distance sensor 3 installed at the top of the feeding station 17, and determines whether the operator's arm has completely withdrawn from the magnet automatic filling device through the gratings 4 arranged on the left and right sides of the equipment base 1. If the bracket 14 has been loaded and the operator's arm has completely withdrawn from the magnet automatic filling device, then step S2 is entered;

[0099] While loading the above-mentioned materials, the preparation of the magnet 15 is carried out synchronously to improve production efficiency, which specifically includes: driving the magnet feeding member 73 to reach the magnet picking position. At this time, the magnet storage through-hole 721, the magnet passage through-hole 712 and the magnet temporary storage hole 731 are coaxial. The lowermost magnet 15 slides down from top to bottom into the magnet temporary storage hole 731, and then drives the magnet feeding member 73 together with the magnet 15 located in the magnet temporary storage hole 731 to reach the magnet feeding position; the magnet 15 can be integrally placed into the magnet storage bin 72 in a stacked manner. The magnet storage bin 72 can be semi-transparent for easy viewing of the remaining quantity. When the magnet feeding member 73 slides to the magnet picking position, due to the self-gravity of the magnet 15, it will integrally slide into the magnet temporary storage hole 731. When the magnet 15 needs to be filled, the magnet feeding member 73 receives an instruction to slide to the magnet feeding position. At this time, the lowermost magnet 15 is left in the magnet temporary storage hole 731 for the next grasping;

[0100] S2. Install the magnet, that is, place the magnet 15 on the bracket 14. The rotary drive unit 16 drives the turntable 5 to rotate, and rotates the bracket 14 that has completed the feeding to the magnet installation station 18. The magnet filling arm 8 rotates to the upper part of the magnet 15 in the magnet temporary storage hole 731 of the magnet feeding member 73, then descends, adsorbs the magnet 15 through the suction cup on the magnet filling arm 8, then ascends and rotates to the side opening 141 of the bracket 14, and then descends to release the magnet 15 onto the magnet filling counterbore 142 of the bracket 14. After the magnet filling arm 8 leaves the bracket 14, step S3 is entered;

[0101] S3. Press fit. The rotary drive unit 16 drives the turntable 5 to rotate, and rotates the bracket 14 that has completed the magnet installation to the press fit station 19. The magnet press fit arm 9 rotates to the side opening 141 of the bracket 14, then descends, and presses the magnet into the magnet filling counterbore 142 of the bracket 14. The magnet press fit arm 9 maintains the press fit state for a preset time. For example, the magnet press fit arm 9 maintains the press fit state for 3S. The magnet and the magnet filling counterbore 142 of the bracket 14 are in an interference fit. After the magnet press fit arm 9 leaves the bracket 14, step S4 is entered;

[0102] S4. Paste the gasket. The rotary drive unit 16 drives the turntable 5 to rotate, and rotates the bracket 14 that has completed the magnet press fit to the gasket pasting station 20. The gasket fitting arm 10 rotates above the gasket 115, then descends, adsorbs the gasket 115 through the suction cup on the gasket fitting arm 10, such as a mylar sheet, then ascends and rotates to the side opening 141 of the bracket 14, and then descends to paste the gasket 115 onto the magnet located in the magnet filling counterbore 142 of the bracket 14;

[0103] While the gasket is being applied, the light sensor 1125 senses whether the gasket 115 on the material belt 114 has been removed. If the gasket 115 has been removed, the receiving wheel 113 drives the material belt 114 to move the next gasket to the waiting position for the next gasket to be removed, thus preparing for the next gasket to be removed.

[0104] S5, unloading, the rotary drive unit 16 drives the turntable 5 to rotate, and rotates the bracket 14 of the magnet with the gasket attached to the unloading station 21, and the bracket grabbing arm 13 rotates to the top of the bracket 14, and then descends, and the bracket 14 is clamped by the clamping claw 131 on the bracket grabbing arm 13, and then rises and rotates to the top of the unloading conveyor belt mechanism 12, and then descends, and releases the bracket 14 to the unloading conveyor belt mechanism 12 to complete the unloading, specifically: after the Mylar sheet is attached, it rotates to the next station, which is to transfer the product with the completed magnet assembly to the product assembly line, wherein the clamping claw 131 of the bracket grabbing arm 13 clamps the product, and then rises and rotates to the unloading conveyor belt mechanism 12, releases the clamping claw 131, and the product falls onto the unloading conveyor belt mechanism 12 for transportation, and is transferred to the product assembly line.

[0105] To explain specifically, in an embodiment of the present invention, in step S1, the distance sensor 3 installed on the top of the loading station 17 is used to determine whether the bracket 14 has been installed, including: a preset height change range value, if the distance sensor 3 detects that the distance change value falls within the preset height change range value, it is determined that the bracket 14 has been installed.

[0106] Specifically, in an embodiment of the present invention, in step S1, the gratings 4 set on the left and right sides of the device base 1 are used to determine whether the operator's arm has completely exited the magnet automatic filling device, including: when the gratings 4 on the left and right sides sense an obstacle, the device is in standby mode; when the gratings 4 on the left and right sides do not sense an obstacle, it is considered that the operator's arm has completely exited the device, and the system gives a signal to trigger the rotation drive unit 16 (i.e., the stepping motor) to rotate clockwise (or counterclockwise, which can be set accordingly as needed) to send the bracket 14 to the next workstation.

[0107] The present invention provides an automatic magnet filling device and method, which has the following advantages:

[0108] 1. Through five rotating stations, a series of actions from product placement to product flow into the complete machine assembly line are automated, greatly improving assembly efficiency;

[0109] 2. After the product is placed in the workstation, the distance sensor and the grating 4 sensors work simultaneously to detect whether the product is placed in place and whether the operator's hand has left the equipment. This design is more flexible and safer;

[0110] 3. The magnet storage device 7 is cleverly designed to utilize the weight of the magnets themselves and a simple magnet temporary placement hole 731 to achieve individual magnet stripping, thereby achieving single magnet feeding and avoiding the problem of multiple magnets being fed together due to magnetic attraction;

[0111] 4. The shim feeder 11 uses a light sensor to detect whether the Mylar sheets are in place. Even if one or two Mylar sheets are missing from the material strip 114, the shim feeder 11 can automatically identify and skip them, thus avoiding material leakage.

[0112] 5. The material belt 114 is also designed for recycling. The used material belt 114 can be automatically rolled up by the material receiving wheel 113, which is convenient for replacement, avoids manual sorting, and saves labor.

When the axis of the magnet temporary storage hole intersects the trajectory circle of the suction cup of the magnet filling arm, the magnet feeding member reaches the magnet sending position. The method includes the following steps: S1. Loading: The rotary drive part drives the turntable to rotate, rotates the bracket fixing block on the turntable to the loading station, fixes the bracket to the bracket fixing block, and judges whether the bracket has been loaded through the distance sensor installed at the top of the loading station, and judges whether the operator's arm has completely withdrawn from the magnet automatic filling device through the light grids provided on the left and right sides of the equipment base. If the bracket has been loaded and the operator's arm has completely withdrawn from the magnet automatic filling device, then enter step S2. While performing the above loading, the preparation of the magnet is carried out synchronously, including: driving the magnet feeding member to reach the magnet taking position. At this time, the magnet storage through-hole, the magnet passage through-hole, and the magnet temporary storage hole are coaxial, and the lowermost magnet slides down into the magnet temporary storage hole from top to bottom, and then driving the magnet feeding member together with the magnet in the magnet temporary storage hole to reach the magnet sending position. S2. Upper magnet. The rotation driving part drives the turntable to rotate, rotates the bracket that has completed the feeding to the upper magnet station, rotates the magnet filling arm to the upper part of the magnet temporarily placed in the magnet temporary placement hole of the magnet feeding member, then descends, adsorbs the magnet through the suction cup on the magnet filling arm, then ascends and rotates to the side opening of the bracket, and then descends to release the magnet onto the magnet filling counterbore of the bracket. After the magnet filling arm leaves the bracket, step S3 is entered; S3. Pressing. The rotation driving part drives the turntable to rotate, rotates the bracket that has completed the upper magnet to the pressing station, rotates the magnet pressing arm to the side opening of the bracket, and then descends to press the magnet into the magnet filling counterbore of the bracket. The magnet pressing arm maintains the pressing state for a preset time. The magnet and the magnet filling counterbore of the bracket are in interference fit. After the magnet pressing arm leaves the bracket, step S4 is entered; S4. Attaching the gasket. The rotation driving part drives the turntable to rotate, rotates the bracket that has completed the pressing of the magnet to the gasket attaching station, rotates the gasket attaching arm to the upper part of the gasket, then descends, adsorbs the gasket through the suction cup on the gasket attaching arm, then ascends and rotates to the side opening of the bracket, and then descends to attach the gasket to the magnet located in the magnet filling counterbore of the bracket; While attaching the gasket, the light sensor is used to sense whether the gasket on the tape has been taken away. If the gasket has been taken away, the tape is driven by the take-up wheel to drive the next gasket to the position waiting to be taken; S5. Unloading. The rotation driving part drives the turntable to rotate, rotates the bracket with the magnet that has completed the gasket attachment to the unloading station, rotates the bracket grasping arm to the upper part of the bracket, then descends, clamps the bracket through the jaws on the bracket grasping arm, then ascends and rotates to the upper part of the unloading conveyor mechanism, and then descends to release the bracket onto the unloading conveyor mechanism to complete the unloading.
