DETAILED DESCRIPTION

[0021] The present invention will be further described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0022] Before describing the LED lamp panel magnetic column intelligent assembly machine of the present invention in detail, it is necessary to describe the structure of the magnetic column and the lamp panel 10. Figure 1 As shown, the magnetic column includes a steel column 101 and a magnetic steel 102. The bottom of the steel column 101 is provided with a slot 100. The magnetic steel 102 is magnetic and is adsorbed in the slot 100. The top of the steel column 101 is provided with a threaded hole, and the steel column 101 can be fixed to the lamp panel 10 by screws. The lamp panel 10 is annular and is provided with a through mounting hole. The magnetic column is installed in the mounting hole. At the same time, the lamp panel 10 can be provided with a plurality of SMD LEDs.

[0023] The embodiment of the present invention provides an intelligent assembly machine for magnetic columns of LED lamp panels, such as Figure 2 As shown, it includes a vibration plate 1, a magnetic steel conveying unit, a combination unit 2, a placement unit 3, a transport unit 4 and a manipulator unit 5. The combination unit 2, the transport unit 4 and the manipulator unit 5 can be arranged around the placement unit 3 and can be located around the placement unit 3. The vibration plate 1 and the magnetic steel conveying unit can be arranged around the combination unit 2, and are located on one side and above the combination unit 2, respectively.

[0024] The transport unit 4 transports the lamp panel 10 to be installed with the magnetic column to the placement unit 3. When one lamp panel 10 is assembled, the transport unit 4 continues to transport the next lamp panel 10 to the placement unit 3. The placement unit 3 includes a placement plate and a rotation drive assembly for driving the placement plate to rotate. As shown in the figure, the placement unit 3 may include a placement frame. The rotation drive assembly may be a rotation motor disposed on the placement frame. The output shaft of the rotation motor is coaxially connected to the placement plate. The lamp panel 10 transported by the transport assembly 4 falls onto the placement plate, and the placement plate is driven to rotate by the rotation motor. This allows the mounting holes on the placement plate to be docked with the assembly unit 2 in sequence.

[0025] The vibration plate 1 delivers the steel column 101 to be assembled to the assembly unit 2, and the steel column 101 is delivered to the assembly unit 2 one by one, and the magnetic steel delivery unit delivers the magnetic steel 102 to be assembled to the assembly unit 2. The assembly unit 2 includes a combination component and a docking component, and the combination component is used to combine the delivered steel column 101 and the magnetic steel 102, that is, to place the magnetic steel 102 into the slot 100 of the steel column 101, so that the magnetic steel 102 is adsorbed and fixed on the steel column 101.

[0026] The docking assembly moves the steel column 101 assembled with the magnetic steel 102 to the bottom of the lamp panel 10 and docks the threaded hole of the steel column 101 with the reserved mounting hole on the lamp panel 10 for screw installation and fixing. The manipulator unit 5 includes a screw tightening assembly and a transport assembly. The screw tightening assembly is used to screw the screw into the threaded hole and the mounting hole, and the magnetic column is assembled on the lamp panel 10. After all the mounting holes on the lamp panel 10 are installed with magnetic columns, the transport assembly can move the lamp panel 10 out of the placement plate.

[0027] The working principle of the intelligent assembly machine for magnetic columns of LED lamp panels of this embodiment is as follows: the transport unit 4 conveys the lamp panel 10 to the placement unit 3, and the lamp panel 10 is placed on the placement plate. The rotating drive assembly drives the placement plate to rotate, and adjusts the position of the lamp panel 10 so that the first mounting hole is close to the combination unit 2, so that the docking assembly can perform the docking action with the mounting hole. The vibration plate 1 conveys the steel column 101 to be assembled to the combination assembly, and the magnetic steel conveying unit conveys the magnetic steel 102 to be assembled to the combination assembly. The combination assembly combines the conveyed steel column 101 and the magnetic steel 102, and then conveys them to the docking assembly. The docking assembly moves the steel column 101 to the bottom of the lamp panel 10, and docks the threaded hole of the steel column 101 with the reserved mounting hole on the lamp panel 10. The manipulator unit 5 installs and fixes the screws into the mounting hole and the threaded hole of the steel column 101. In this way, the first mounting hole completes the assembly of the magnetic column. The rotating drive assembly drives the placement plate to rotate, and then adjusts the position of the lamp panel 10 so that the next mounting hole is close to the combination unit 2. The assembly assembly continues to assemble the steel column 101 and the magnetic steel 102 that have been transported, and then transports them to the docking assembly. The docking assembly moves the steel column 101 to the bottom of the lamp panel 10, and docks the threaded holes of the steel column 101 with the mounting holes on the lamp panel 10. The manipulator unit 5 installs and fixes the screws into the mounting holes and the threaded holes of the steel column 101. The above actions are performed in sequence until all the mounting holes are equipped with magnetic columns, and the assembly of the lamp panel 10 is completed. The handling assembly removes the lamp panel 10 from the placement plate, and the transport unit 4 continues to transport the lamp panel 10 to be equipped with magnetic columns to the placement unit 3.

[0028] In one embodiment, the structure of the combined unit 2 will be described in detail. Figure 3 and Figure 4 As shown, the combined assembly includes a bottom plate 21, a base 22 is arranged on the bottom plate 21, and a feed channel 221 and a push channel 222 are provided on the base 22, which are connected to each other. The feed channel 221 and the push channel 222 can be arranged perpendicular to each other, and the push channel 222 extends toward the placement plate. The feed channel 221 and the push channel 222 can specifically be grooves arranged on the upper surface of the base 22, and the push channel 222 can penetrate the base 22 in its extension direction. The feed channel 221 is docked with the vibration plate 1, and specifically, a slide rail 11 can be arranged between the vibration plate 1 and the feed channel 221, and the height of the slide rail 11 near one end of the vibration plate 1 is greater than its height near one end of the feed channel 221, so that the steel column 101 output by the vibration plate 1 will automatically slide into the feed channel 221, and continue to slide into the push channel 222 under the action of inertia. The widths of the slide rail 11, the feed channel 221 and the push channel 222 are set to be slightly larger than the diameter of the steel column 101, so that the steel column 101 can move individually and sequentially.

[0029] A pushing assembly is provided at one end of the pushing channel 222 away from the placement plate, and a blanking block 23 is provided above the other end of the pushing channel 222. The blanking block 23 can be fixed on the upper surface of the base 22, and a suction hole 230 connected to the pushing channel 222 is provided at the top of the blanking block 23. The suction hole 230 is connected to the magnetic steel conveying unit, and the magnetic steel conveying unit conveys a single magnetic steel 102 to the suction hole 230 one by one, and the magnetic steel 102 will fall from the suction hole 230 into the pushing channel 222. The pushing assembly is used to push the steel column 101 in the pushing channel 222 to the bottom of the blanking block 23, and the magnetic steel 102 falls into the slot 100 of the steel column 101. Based on the inherent magnetism of the magnetic steel 102, the magnetic steel 102 will be adsorbed and fixed in the slot 100 of the steel column 101, completing the combined assembly of the magnetic steel 102 and the steel column 101.

[0030] In one embodiment, the docking assembly includes a fixed seat 25 located on the outside of the blanking block 23 (i.e., the side close to the placement plate), a magnetic plate 26 rotatably connected to the fixed seat 25, and a magnetic driver 28 disposed on the fixed seat 25. The fixed seat 25 can be fixed to the outer wall of the bottom plate 21, the fixed plate 27 is fixed to the bottom plate 21, and the magnetic driver 28 is fixed to the fixed plate 27. The magnetic driver 28 can be a motor, and its output shaft passes through the fixed seat 25 from the outside of the fixed seat 25 and is connected to the magnetic plate 26 on the inside of the fixed seat 25. The rotation of the motor drives the magnetic plate 26 to rotate. The magnetic plate 26 is magnetic and can absorb the magnetic steel 102 which is also magnetic. The pusher channel 222 will extend to the bottom of the magnetic plate 26. When the magnetic steel 102 and the steel column 101 are assembled, the pusher assembly pushes the assembled steel column 101 to the bottom of the magnetic plate 26. Since the magnetic plate 26 is magnetic, the magnetic plate 26 will absorb the steel column 101 below it, and the side of the steel column 101 with the magnetic steel 102 is tightly fixed on the lower surface of the magnetic plate 26. The magnetic driver 28 drives the magnetic plate 26 to rotate upward, and the magnetic plate 26 flips 180 degrees. At this time, the end of the steel column 101 with the threaded hole faces upward, so that it can be docked with the mounting hole of the lamp panel 10, and then the magnetic column is assembled to the lamp panel 10 by screws.

[0031] Furthermore, two fixing seats 25 are provided, both of which are fixed on the outside of the bottom plate 21, and a certain distance is spaced between the two fixing seats 25, and the magnetic attraction plate 26 is located between the two fixing seats 25. The two fixing seats 25 limit the output shaft of the motor to keep the axial rotation to prevent position deviation.

[0032] The pushing assembly includes a cylinder 241, a push rod arranged on the cylinder 241, and a push plate 242 arranged at the end of the push rod. The cylinder 241 drives the push rod to extend outward or retract inward, and the push plate 242 moves accordingly. The push plate 242 pushes the steel column 101 to move along the pushing channel 222.

[0033] In one embodiment, the manipulator unit 5 will be described in detail. The manipulator unit 5 includes a multi-axis manipulator 53, which can move at multiple angles and in multiple directions. The screwing assembly 51 and the transport assembly 52 are both arranged at the end of the multi-axis manipulator 53, and the multi-axis manipulator 53 will drive the screwing assembly 51 and the transport assembly 52 to move. The screwing assembly 51 includes an automatic screwdriver, which can be a commonly used robot screwing device, such as an electric screwdriver, which magnetically absorbs the screws and drives the screws to rotate to perform the screwing action. A material box 50 for loading screws is provided on one side of the multi-axis manipulator 53. The multi-axis manipulator 53 drives the automatic screwdriver to move to the material box 50, and the automatic screwdriver absorbs the screws from the material box 50. The multi-axis manipulator 53 then moves the automatic screwdriver with the screws absorbed to the top of the mounting hole, and then drives the screws on the automatic screwdriver to dock with the mounting hole. The electric screwdriver starts to perform the screwing action, so that the screws are installed in the mounting hole and the threaded hole of the steel column 101, and the magnetic column is assembled.

[0034] In one embodiment, the transport assembly 52 includes a fixed plate, two claws arranged at both ends of the fixed plate, and a claw driver that drives the two claws to clamp or release. The claws can clamp the lamp panel 10 or release the lamp panel 10, and cooperate with the multi-axis robotic arm 53 to move the lamp panel 10 to different workstations.

[0035] In one embodiment, the LED lamp panel magnetic column intelligent assembly machine also includes a material transfer unit 6, and the transport component 52 is used to move the assembled lamp panel 10 from the placement plate to the material transfer unit 6. The material transfer unit 6 is used to transport the assembled lamp panel 10 to the next workstation, or drop it into a material receiving box.

[0036] like Figure 2 As shown, the material moving unit 6 and the transport unit 4 can adopt the same transport structure, both of which include a bracket 41 and a transport roller 42 arranged on the bracket 41. The transport roller 42 is connected to a corresponding driver, and the driver drives the transport roller 42 to rotate, thereby driving the lamp panel 10 to move.

[0037] In one embodiment, a chuck 31 is provided on the surface of the placing plate, which protrudes from the surface of the placing plate and is coaxially arranged with the placing plate. The diameter of the chuck 31 is smaller than the inner diameter of the lamp panel 10, and the diameter of the placing plate is smaller than the outer diameter of the lamp panel. In this way, the lamp panel 10 can be placed on the placing plate. At the same time, the chuck 31 in the middle plays a limiting role to prevent the lamp panel 10 from being laterally displaced on the placing plate, thereby ensuring precise assembly alignment.

[0038] The above contents are further detailed descriptions of the present invention in combination with specific implementation methods, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention.
