Description

Technical Field

[0001] The utility model relates to the technical field of chip mounters, in particular to a chip mounter and a chip feeder. Background Art

[0002] A chip mounter is a device used for mounting electronic components. It can automatically and accurately mount electronic components on printed circuit boards. The chip mounter uses advanced visual recognition systems and robotic arms to locate and place components, greatly improving production efficiency and quality.

[0003] The existing SMT feeder conveys circuit boards in a linear manner. Therefore, in order to convey the circuit boards forward, only the two ends of the circuit boards can be clamped and fixed during the conveying process. Therefore, the circuit boards need to be clamped at both ends of the feeder to ensure that the circuit boards do not loosen. Clamping the circuit boards from both ends will make both ends of the circuit boards prone to wear, causing burrs at both ends of the circuit boards, reducing the quality of the final product. Therefore, a new type of SMT machine is needed to solve this problem. Utility Model Content

[0004] In order to solve the above technical problems, the utility model proposes a chip mounter and a chip feeder, which can clamp and fix a circuit board from four directions and transport the circuit board in a circular conveying manner.

[0005] The technical solution to achieve the purpose of the utility model is: a patch machine and a patch feeder, including a feeding assembly, the feeding assembly including a chassis, a motor, a turntable, a sliding hole, a sliding rod and a telescopic rod, the motor is fixedly connected to the chassis, the turntable is fixedly connected to the output shaft of the motor, a plurality of groups of the sliding holes are opened on the turntable, the interior of the sliding holes are slidably connected to the sliding rods, the sliding rods are fixedly connected to the telescopic rods, and a clamping assembly is arranged between the sliding rod and the chassis.

[0006] Preferably, the feeding assembly further comprises a gasket, a plurality of the gaskets are fixedly connected to the turntable, and the plurality of gaskets are respectively located between the plurality of groups of telescopic rods.

[0007] Preferably, the clamping assembly comprises a through hole and a lifting ring, the through hole is provided on each of the sliding rods, and a plurality of lifting rings are slidably connected between the through holes.

[0008] Preferably, the clamping assembly further comprises connecting rods, lifting columns and springs, the multiple connecting rods are respectively fixedly connected to the multiple lifting rings, the multiple lifting columns are respectively fixedly connected to the multiple connecting rods, and the multiple springs are respectively fixedly connected between the multiple lifting columns and the turntable.

[0009] Preferably, the clamping assembly further comprises a limiting groove, the limiting groove is provided on the chassis, and the bottoms of the plurality of lifting columns are all slidably connected to the chassis.

[0010] Another technical solution for achieving the purpose of the utility model is: a chip mounter, including a chip mounter body and a chip feeder, the chip feeder is located inside the chip mounter body, and a feed port is opened on the chip mounter body.

[0011] Compared with the prior art, the utility model has the following significant advantages:

[0012] First, in the utility model, when the motor is started, the output shaft of the motor rotates to drive the turntable to rotate. When the turntable rotates, the multiple lifting columns at the bottom thereof will also slide on the chassis. When the lifting columns move to the limit grooves, the springs originally in a compressed state will cause the lifting columns to fall into the limit grooves. The descent of the lifting columns will drive the connecting rod and the lifting ring to move downward. The descent of the lifting ring will cause the four sliding rods connected thereto to expand outward together, thereby driving the telescopic rod to expand outward. The limit groove is located at the feed inlet, so the telescopic rod will expand at the feed inlet to facilitate the placement of the circuit board between the four telescopic rods.

[0013] Second: In the utility model, when the circuit board is placed between the four telescopic rods, the motor can be started again to rotate the turntable, and then the lifting column slides out of the limit slot, and the four telescopic rods gather together and clamp the circuit board to fix the circuit board. The circuit board will then be sent into the interior of the SMT machine body to complete the SMT work. After the SMT is completed, the circuit board will rotate one circle with the turntable and finally return to the feed port. At this time, the four telescopic rods clamping the circuit board will unfold again to facilitate the removal of the circuit board that has completed the SMT. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Furthermore, the feeding assembly 3 also includes a gasket 37, and multiple gaskets 37 are fixedly connected to the turntable 33. The multiple gaskets 37 are respectively located between multiple groups of telescopic rods 36. When the telescopic rods 36 clamp the circuit board, the circuit board will shake. The surface of the gasket 37 is smooth. Placing the circuit board on the gasket 37 can prevent the circuit board from being scratched when it shakes.
