[0023] Refer to the following Figure 1-Figure 5 A positioning and identification device for an LED lamp production carrier according to some embodiments of the present application is described.
[0024] A positioning and identification device for LED lamp production carriers includes a work frame 1, a conveying device 27, an identification device 28, a lifting device 29, and a carrier 30. The conveying device 27 is used to convey the carrier 30, the identification device 28 is used to stop and identify the carrier 30 and transmit the position information of the carrier 30 back, and the lifting device 29 lifts the carrier 30 after the carrier 30 is stopped. The conveying device 27 includes a conveying frame 31, which is installed on the work frame 1. The conveying frame 31 includes a first longitudinal beam 31a and a second longitudinal beam 31b. A conveyor belt 32 is laid on the two longitudinal beams. A first cross beam 46a and a second cross beam 46b are provided between the two longitudinal beams. Taking the direction of movement of the conveyor belt 32 as the front side, the front side is the first cross beam 46a, and the rear side is the second cross beam 46b. An RFID identifier 33 is installed on the inner side of the first longitudinal beam 31a. The identification device 28 includes a fixed frame 34, a baffle 35, a blocking cylinder 36, and a magnetic sensor 37. With the direction of movement of the conveyor belt 32 as the front side, the fixed frame 34 is installed on the front side of the first beam 31b of the conveyor frame 31, and the magnetic sensor 37 is installed on the rear side of the fixed frame 34 by screws. The blocking cylinder 36 is installed on the front side of the fixed frame 34 by screws. The baffle 35 is connected above the blocking cylinder 36. The rear side of the baffle 35 is recessed to form a guide groove 47, and the front side of the fixed frame 34 is protruding to form a guide block 48. The guide groove 47 of the baffle 35 matches the guide block 48 of the fixed frame 34, so that the baffle 35 can move up and down with the lifting and falling of the blocking cylinder 36. Two oil pressure buffers 38 are installed on the rear side of the baffle 35, which are used to stop the carrier 30 transmitted here. The lifting device 29 comprises a mounting plate 39, a lifting cylinder 40, and a lifting plate 41. The mounting plate 39 is mounted on the work frame 1, within the rectangular area enclosed by the longitudinal and transverse beams of the conveyor frame 31. The lifting cylinder 40 is mounted on the mounting plate 39, and the lifting plate 41 is mounted on the lifting cylinder 40. Two locating pins 42 are located at the diagonally opposite corners of the lifting plate 41. The carrier 30 is rectangular, with magnetic metal sheets 43 mounted on opposite edges of its bottom surface. The bottom surface also has two locating holes 44 and an RFID tag 45. Each carrier is equipped with a separate RFID tag.
[0025] When the production line starts working, the carrier 30 is mounted on the conveyor belt 32 and is transferred from the processing station where the previous process has been completed to the processing station where the process is to be carried out. The RFID tag 45 on the bottom surface of the carrier 30 is adapted to the RFID identifier 33 so that when the carrier 30 just enters the working area of the processing station, the RFID tag 45 contacts the RFID identifier 33, and the RFID identifier 33 identifies the tag information and transmits a signal back to the PLC control center, which plays a role in tracking the production line process. In addition, when the work starts, the lifting cylinder 40 is in a falling state, and the lifting plate 41 is lower than the horizontal plane of the conveyor belt 32, which will not hinder the passage of the carrier 30. The blocking cylinder 36 is in a lifting state, and the baffle 35 is higher than the horizontal plane of the conveyor belt 32. During the movement, the carrier 30 will hit the oil pressure buffer 38 on the baffle 35 and stop. At this time, the position of the carrier 30 is just the working position for the process. At the same time, the magnetic metal sheet 43 on the bottom edge of the carrier 30 contacts the magnetic sensor 37, which sends a signal to the PLC control center, which in turn issues a command to raise the lifting cylinder 40. The two locating holes 44 on the bottom of the carrier 30 are aligned with the two locating pins 42 on the lifting plate 41. When the lifting cylinder 40 is raised, the two locating pins 42 on the lifting plate 41 insert into the two locating holes 44 on the bottom of the carrier 30, completing the positioning. The lifting plate 41 then lifts the carrier 30 off the conveyor belt 32, allowing the PLC control center to control the robotic arm for processing. Once the processing is complete, the lifting cylinder 40 descends, returning the carrier 30 to the conveyor belt 32, freeing the locating holes 44 from the locating pins 42. The blocking cylinder 36 then descends, causing the baffle 35 to descend below the level of the conveyor belt 32. The carrier 30 then moves along the conveyor belt 32, crossing the baffle 35 to the next station. When the carrier 30 leaves, the blocking cylinder 36 is lifted up, forming a complete working cycle.
[0026] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
