The loading tray is installed through the alignment seat and the alignment block, which can facilitate the replacement of loading trays of different specifications. When replacing the loading tray, the bayonet is pressed so that the bayonet can compress the spring into the inside of the pin groove, thereby separating the bayonet from the pin hole, and then separating the alignment block from the alignment seat, so that the loading tray can be replaced. The piston rod of the first servo cylinder is extended and retracted, which can facilitate the patch processing, so that the height of the loading tray can be assisted to rise and fall;

[0030] 2. As described in 1, when the photoelectric sensor 1 and the hot air blower need to be used, first pass the support plate through the bottom of the loading plate and between the two adjacent servo cylinders 1, and fit the lower end of the loading plate with the upper end of the support plate to achieve preliminary clamping and positioning.

Then, the hot air blower, photoelectric sensor 1 and the air nozzle are installed on both sides of the support plate in turn. The photoelectric sensor 1 will be installed on the side plate so that it can sense each other with the photoelectric sensor 2 when the slide moves, so as to achieve the position calibration of the slide on the slide rail.

[0031] 3. As described in 2, when the slide needs to be moved, the servo motor 1 can be used to drive the rotating shaft 1, and the rotating shaft 1 can drive the shaft rod 1 to rotate, so that the roller 1 can roll, thereby rolling in contact with the slide rail to drive the slide on the slide rail. When the slide slides, in order to reduce the contact friction resistance generated during the vertical support process, the roller 2 can roll to make the slide on the slide rail slide more smoothly.

In order to ensure the linear guide For the normal operation of the rail pair, it is usually necessary to add lubricating oil regularly to reduce wear and extend the service life. A servo cylinder 3 38 is arranged above the guide rail pair slide 2 35. The lower end of the servo cylinder 38 is fixedly assembled with the guide rail pair slide 2 35 by screws. A piston rod 3 for extension and retraction is arranged inside the servo cylinder 38. A support plate 36 is fixedly arranged on the upper end of the piston rod 3 by screws. The support plate 36 is a disc structure. A servo motor 2 37 is arranged above the support plate 36. The outer ring wall of the servo motor 2 37 is fixedly assembled with the surface of the support plate 36 by a bracket. A rotating shaft 2 for driving is arranged inside the servo motor 2 37. When the suction cup needs to be adjusted 3003 is adjusted laterally, and the guide rail auxiliary slide 1 32 slides on the guide rail auxiliary guide 1 30 to achieve horizontal stable movement in the X-axis direction, and the guide rail auxiliary slide 2 35 slides on the guide rail auxiliary guide 2 33 to achieve horizontal stable movement in the Y-axis direction. The piston rod 3 of the servo cylinder 3 38 is extended and retracted to achieve vertical stable movement in the Z-axis direction. When the suction cup 3003 needs to be rotated and matched with the external feeding structure to absorb the new LED lamp beads to be installed, the servo motor 2 37 is driven to make the rotating shaft 2 drive the suction cup 3003 to rotate horizontally and adjust the position to meet the displacement requirements of the patch processing;

[0057] A connecting plate 3001 is fixed on the rotating shaft 2 of the servo motor 2 37, and a limiting seat 3002 is arranged below the connecting plate 3001. The upper end of the limiting seat 3002 is fixed to the surface of the connecting plate 3001 through a bracket, and the inner side of the limiting seat 3002 is slidingly and tightly set with the outer ring wall of the support plate 36, which can ensure that the connecting plate 3001 plays an auxiliary support effect when rotating. An air pump 3005 is fixedly installed on the upper end of the connecting plate 3001, and a suction cup 3003 is penetrated at the end of the connecting plate 3001 away from the servo motor 2 37. The penetration position of the suction cup 3003 and the connecting plate 3001 is fixed by screws, and a plurality of suction nozzles 3004 are fixedly connected to the lower end of the suction cup 3003. The distribution of the suction nozzles 3004 can be set according to the actual position of the LED lamp beads on the circuit board, and the suction nozzles 3004 can also be adsorbed from the external feeding position. The corresponding LED lamp beads are then moved or rotated to the top of the loading plate 27. Through further movement and coordination, the LED lamp beads can be installed at the designated position on the circuit board and in the area where solder paste is applied, so as to realize patch installation. The suction position of the air pump 3005 is fixedly connected with the outlet position of the suction cup 3003 through a pipeline. An extension plate 3006 is fixed to the side of the connecting plate 3001. The extension plate 3006 is symmetrically distributed along the longitudinal center axis of the connecting plate 3001. A photoelectric sensor 2 3007 is fixed to the lower end of the extension plate 3006. The photoelectric sensor 2 3007 is corresponding to the photoelectric sensor 1 2008. When the slide 12 moves to the position of the suction cup 3003 of the patch, the mutual induction of the two photoelectric sensors can realize the calibration of the positions on both sides, thereby ensuring the patch process and the accuracy of the position of the LED lamp beads on the circuit board.

[0058] The mounting method of the LED lamp bead is as follows:

[0059] Step 1: Place the circuit board coated with solder paste on the loading tray 27, and through the extension and retraction of the piston rod 2 of the servo cylinder 28, the clamping plate 29 can clamp and position the circuit board from at least four directions;

[0060] Step 2: By extending and retracting the piston rod of the servo cylinder 20, it is convenient to carry out patch processing so that the height of the loading plate 27 can be assisted to rise and fall;

[0061] Step 3: The servo motor 15 is used to drive the rotating shaft 1, which can drive the shaft 14 to rotate, so that the roller 16 can roll, so that the slide 12 is driven on the slide rail 11, and the roller 2 110 rolls, so that the slide 12 slides on the slide rail 11 more smoothly;

[0062] Step 4: When the slide 12 moves to the position of the suction cup 3003, the photoelectric sensor 1 2008 and the photoelectric sensor 2 3007 sense each other to achieve position calibration of the slide 12 on the slide rail 11;

[0063] Step 5: By sliding the guide rail sub-slide 1 32 on the guide rail sub-guide 1 30, horizontal stable movement in the X-axis direction can be achieved, and by sliding the guide rail sub-slide 2 35 on the guide rail sub-guide 2 33, horizontal stable movement in the Y-axis direction can be achieved. By extending and retracting the piston rod 3 of the servo cylinder 3 38, vertical stable movement in the Z-axis direction can be achieved.

[0064] Step 6: By driving the servo motor 2 37, the rotating shaft 2 can drive the suction cup 3003 to rotate horizontally to adjust the position to meet the displacement requirements of the patch processing;

[0065] Step 7: Through the air pumping effect of the air pump 3005, the suction nozzle 3004 on the suction cup 3003 can generate a strong suction force, and the suction nozzle 3004 can also absorb the corresponding LED lamp bead from the external feeding position, and then move or rotate to the top of the loading plate 27. Through further movement and coordination, the LED lamp bead can be installed at the designated position on the circuit board and the area where the solder paste is applied, so as to realize the patch installation;

[0066] Step 8: Finally, after the patch is completed, the hot air blower 2005 is started so that the hot air blower 2005 can deliver hot air, and the air nozzle 2006 blows out a hot air flow to assist in drying the solder paste connecting the already patched LED lamp beads and the circuit board.

[0067] When implementing

[0068] When it is necessary to mount the LED lamp beads and the circuit board, the circuit board coated with solder paste is placed on the loading tray 27. The piston rod 2 of the servo cylinder 28 is extended and retracted, so that the clamping plate 29 can clamp and position the circuit board from at least four directions. The loading tray 27 is installed through the alignment seat 22 and the alignment block 21, which can facilitate the replacement of loading trays 27 of different specifications. When replacing the loading tray 27, the bayonet 24 is pressed so that the bayonet 24 can compress the spring 25 and enter the inside of the pin groove 23, thereby separating the bayonet 24 from the pin hole 26, and then separating the alignment block 21 from the alignment seat 22, and the replacement of the loading tray 27 can be completed. The piston rod 1 of the servo cylinder 20 is extended and retracted, which can facilitate the patch processing, so that the height of the loading tray 27 can be assisted to rise and fall;

[0069] When the photoelectric sensor 2008 and the hot air blower 2005 need to be used, the support plate 2001 is first passed through the bottom of the loading tray 27 and between two adjacent servo cylinders 20, and the lower end of the loading tray 27 is fitted with the upper end of the support plate 2001 to achieve preliminary clamping and positioning. At this time, the threaded rod 2003 and the built-in sleeve 2002 are penetrated and set, and then, the threaded sleeve 2004 with a knob and the threaded rod 2003 are threadedly connected with each other, so that the support plate 2001 and the loading tray 27 can be locked and fixed, and then the hot air blower 2005, the photoelectric sensor 2008 and the air nozzle 2006 are installed on both sides of the support plate 2001 in turn, and the photoelectric sensor 2008 will be installed on the side plate 2007 so that when the slide 12 moves to the position of the suction cup 3003, the photoelectric sensor 2008 and the photoelectric sensor 2 3007 can sense each other to achieve the position calibration of the slide 12 on the slide rail 11;

[0070] When the slide 12 needs to be moved, the servo motor 15 can drive the rotating shaft 1, and the rotating shaft 1 can drive the shaft 14 to rotate, so that the roller 16 can roll, thereby rolling contact with the slide rail 11, and the slide 12 can be driven on the slide rail 11. When the slide 12 slides, in order to reduce the contact friction resistance generated in the vertical support process, the roller 2 110 can roll to make the slide 12 slide more smoothly on the slide rail 11.

[0071] The processor 1006 is provided with a wireless signal transceiver inside, which can receive or feedback the control signal when the slide 12 moves. The processor 1006 is also connected to the servo cylinder 1 20, the servo cylinder 28, the servo motor 15, the hot air blower 2005, and the photoelectric sensor 2008 through data lines. The processor 1006 is also connected to the rechargeable battery 1001 through a transmission line. The rechargeable battery 1001 can power the processor 1006. The processor 1006 is used as a hub to power each electrical appliance on the slide 12. The processor 1006 is connected to the rechargeable battery 1001 through a transmission line ... 006 then controls each electrical appliance in turn after receiving external instructions, so as to ensure that the transmission of the circuit board is stable when the circuit board and the LED lamp beads are mounted. When the rechargeable battery 1001 needs to be replaced, the threaded cap 1005 is rotated so that the threaded cap 1005 can be manually rotated and threadedly separated from the threaded column 1003, so that the threaded cap 1005 can be disengaged from the threaded column 1003, and the threaded column 1003 can be separated from the collar 1004, and the replacement of the rechargeable battery 1001 that is currently out of power with the rechargeable battery 1001 that is fully charged is completed;

[0072] When patch processing is required, the suction cup 3003 is first adjusted horizontally, and the guide rail sub-slide 1 32 slides on the guide rail sub-guide rail 1 30 to achieve horizontal and stable movement in the X-axis direction. The guide rail sub-slide 2 35 slides on the guide rail sub-guide rail 2 33 to achieve horizontal and stable movement in the Y-axis direction. The piston rod 3 of the servo cylinder 38 is extended and retracted to achieve vertical and stable movement in the Z-axis direction. When the suction cup 3003 needs to be rotated and matched with the external feeding structure to absorb the new LED lamp beads to be installed, Driven by the servo motor 37, the rotating shaft 2 can drive the suction cup 3003 to rotate horizontally to adjust the position to meet the displacement requirements of the patch processing. Through the suction effect of the air pump 3005, the suction nozzle 3004 on the suction cup 3003 can generate a strong suction force. The suction nozzle 3004 can also absorb the corresponding LED lamp beads from the external feeding position, and then move or rotate to the top of the loading plate 27. Through further movement and coordination, the LED lamp beads can be installed at the specified position on the circuit board and in the area where the solder paste is applied to achieve patch installation.
