Description

Technical Field

[0001] The utility model relates to the technical field of LED light source mounting machines, in particular to a substrate tooling for LED light source mounting machines. Background Art

[0002] SMT machine: also known as "mounting machine" or "surface mounting system". When the existing SMT machine mounts LED light sources, the positions of the corresponding patches on the PCB board will be coated with adhesive and solder paste. During mounting, the PCB board moves to the mounting station with the transmission device, and the mounting station positions the PCB board through the positioning block. Then, several suction nozzles on the SMT machine first move to the LED light source patch, and the vacuum equipment connected to the suction nozzles is operated to generate negative pressure at the suction nozzles to adsorb the LED light source patches. Then, multiple suction nozzles move to the top of the PCB board, and at this time, the vacuum nozzles are closed, and the blowing program is run at the same time, the LED light source patches are placed at the corresponding positions on the PCB board, and the above process is repeated to complete the mounting of the LED light source patches on the PCB board.

[0003] However, in the above-mentioned patch process, due to the high speed of patch, the patch machine will generate downward force on the LED light source patch, so that the LED light source patch quickly contacts with the adhesive and solder paste, and then the nozzle is reset to continue the next patch process. When the nozzle is reset, it will drive the PCB board to float upward, but the fast production cycle will cause the nozzle to drive the LED light source patch to move above the PCB board before the PCB board falls into place, affecting the normal progress and quality of the placement.

A longitudinal moving component for driving the two longitudinal bottom plates to move closer to or away from each other is installed on the tooling bottom plate;

[0034] It also includes a pressing component for pressing the PCB board.

[0035] In this way, according to the size of the PCB board, the lateral bottom plate is moved by the lateral moving component, and the longitudinal bottom plate is moved by the longitudinal moving component, and then the positions of the lateral positioning plate and the longitudinal positioning plate are adjusted to achieve positioning for PCB boards of different sizes. After the positioning is completed, the clamping component clamps the edge of the PCB board, and then the LED light source mounting operation can be performed on the PCB board through the mounting machine.

[0036] The substrate tooling of the present application is set for a rectangular PCB board.

[0039] In this way, when adjusting the position between the two transverse positioning plates, the transverse knob is turned to drive the transverse screw connected to the transverse knob to rotate, and through the transmission of the transverse rack and the transverse gear, the synchronous rotation of the other transverse screw is achieved, thereby achieving the synchronous adjustment of the position of the two transverse positioning plates.

[0040] During implementation, the longitudinal moving assembly includes two longitudinal grooves opened on the tooling bottom plate, longitudinal screws 12 are installed in the longitudinal grooves through bearings, one of the longitudinal screws passes through the tooling bottom plate and is fixed with a longitudinal knob 13 outwardly, a longitudinal connecting block is threadedly connected to the longitudinal screw, the upper end of the longitudinal connecting block is fixedly connected to the longitudinal bottom plate, the longitudinal bottom plate is slidably fitted with the tooling bottom plate, and the lower end of the longitudinal connecting block is fixedly connected to two longitudinal racks 15 through a longitudinal connecting plate 14;

[0046] In this way, after the PCB board is positioned, the cylinder rod of the clamping cylinder contracts, which in turn drives the clamping arm connected to the cylinder rod to rotate, and the clamping arm rotates around the hinge position between the support arm and the connecting arm, which in turn drives the pressing plate to rotate downward, thereby achieving the clamping of the PCB board. After the patch is completed, the cylinder rod of the clamping cylinder extends, driving the clamping arm to rotate in the opposite direction, and then driving the pressing plate to rotate in the opposite direction, thereby releasing the clamping of the PCB board.

[0047] During implementation, a rubber block (not shown) is fixed to the pressing end of the pressing plate, so that the PCB board 23 can be pressed better.
