Description

Technical Field

[0001] The utility model relates to the technical field of chip mounters, in particular to a conveying component for an LED light source chip mounter. Background Art

[0002] The production and processing of LED light sources requires tinning on the PCB board, and then the LED lamp beads are mounted on the corresponding points on the PCB board through the placement machine. In order to improve the production and processing efficiency, the PCB board is transported through the conveying component. Since the PCB board is a flexible board, it cannot be transported directly during transportation. Therefore, the PCB board needs to be fixed on the base first, and the base is driven to move by the conveying component. After it is transported to the right place, the placement machine will start to work. At present, the conveying component mostly uses two conveyor belts, and the two conveyor belts support the two sides of the base respectively.

[0003] However, there is no connection between the conveying component and the base. The base is only placed on the conveying component, which causes the PCB board and the substrate to shake during mounting, resulting in poor stability and affecting the accuracy of the mounting point of the LED lamp beads. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a conveying component for an LED light source placement machine that has a stable connection, a simple structure, and is easy to use.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A conveying assembly for an LED light source mounting machine, comprising a frame and a substrate, wherein the frame is U-shaped and opened upward, and conveyor belts are arranged on both sides of the frame, and the conveyor belts are sleeved on the outside of a driving roller and a driven roller, and the driving roller and the driven roller are rotatably connected to the frame, and the driving roller passes through the frame and is fixedly connected to the output shaft of a conveying motor, and the conveying motor is fixedly installed on the outside of the frame;

[0007] The two sides of the base plate are slidably fitted with the frame;

[0008] Two bottom plates are fixedly mounted on the frame, a photoelectric switch is mounted on one side of the bottom plate, and a base plate locking structure is mounted between the bottom plate and the base plate;

[0009] The base plate locking structure comprises a locking block fixedly mounted at the lower end of the base plate, a rotating shaft is rotatably mounted on the bottom plate facing the locking block, and a rotating disk is fixed at the upper end of the rotating shaft. A rotating structure for driving the rotating shaft to rotate is also mounted on the base, a lifting structure is fixedly mounted on the rotating disk, and the lifting structure is fixedly connected to the locking disk through a limit plate, two locking pins are evenly distributed and fixed on the circumference of the locking disk, a locking groove is opened on the circumference of the locking block, the locking groove is in an inverted L shape, the lower end of the locking groove is open, and the locking pin is slidably matched with the locking groove.

[0010] In this way, the PCB board is bonded to the substrate, and the substrate is placed on the conveyor belt. The two sides of the substrate are slidably fitted with the frame. The two sides of the frame have a positioning effect on the substrate. The conveying motor drives the active roller to rotate, thereby driving the conveyor belt to rotate, and then the substrate is conveyed. When the substrate is conveyed, the photoelectric switch detects that the substrate is in place, and the conveying motor stops. Two bottom plates are provided, corresponding to the solder paste application station and the placement machine iron sheet station. After the substrate is in place, the lifting structure drives the limit plate to rise, the locking disk to rise, and drives the locking pin to insert into the locking groove. Then the rotating structure drives the shaft to rotate, and then the locking disk is driven to rotate by the turntable, the lifting structure and the limit plate to drive the locking pin to rotate along the locking groove. The locking pin rotates to the inner side of the locking groove to complete the position locking of the locking block. Then the placement machine can mount the lamp beads on the PCB board. By setting the substrate locking structure, the shaking of the substrate can be reduced and the stability of the patch can be improved.

[0011] Among them, the rotating structure includes a motor base fixedly mounted on the base plate, a rotating motor is fixedly mounted on the motor base, the output shaft of the rotating motor is arranged downward and a driving pulley is fixedly mounted thereon, a driven pulley is fixedly mounted on the outer side of the rotating shaft, and the driving pulley and the driven pulley are connected by a belt.

[0012] Wherein, the lifting structure is a cylinder or an electric push rod.

[0013] Wherein, the substrate locking structure is provided in two.

[0014] Wherein, guide blocks are fixedly installed on both sides of the frame, and guide inclined surfaces are arranged on the inner sides of the guide blocks.

[0015] Wherein, a positioning groove is provided on the base plate.

[0016] Wherein, support blocks are fixedly installed on both sides of the lower end of the base plate, and the lower ends of the support blocks are located below the locking blocks.

[0017] In summary, the conveying assembly for the LED light source placement machine has the advantages of stable connection, simple structure and easy use. BRIEF DESCRIPTION OF THE DRAWINGS
