Description

Technical Field

[0001] This utility model relates to the field of chip mounter technology, specifically a printed circuit board chip mounter. Background Technology

[0002] A pick-and-place machine (PPC) is an indispensable key piece of equipment in the electronics manufacturing industry. It is primarily used to precisely mount tiny electronic components onto designated locations on printed circuit boards (PCBs). Through a combination of a highly automated control system and a precise mechanical structure, the PPC achieves automated component placement, significantly improving production efficiency and product quality.

[0003] In existing printed circuit board placement machines, the circuit board may shift during the process of being transported to the placement head, affecting the placement accuracy. In addition, the nozzle is usually a fixed design, and replacement requires disassembling multiple parts or using special tools, which is time-consuming and labor-intensive. It is inconvenient to replace the nozzle individually and it is difficult to adapt to the placement needs of components of different sizes. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a printed circuit board placement machine to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a printed circuit board placement machine, comprising a machine body, an internal belt conveyor and a feeder, a first motion mechanism on the top of the machine body, a second motion mechanism on the outer surface of the first motion mechanism, a third motion mechanism on the outer surface of the second motion mechanism, a placement head on the outer surface of the third motion mechanism, an installation tube at the bottom of the placement head, a suction nozzle at the bottom of the installation tube, a second magnetic ring fixedly connected to the outer surface of the suction nozzle, a first magnetic ring at the side of the bottom of the installation tube, an insertion rod fixedly connected to the upper surface of the suction nozzle, a fixed seat fixedly connected to the side of the upper surface of the belt conveyor, an electric cylinder fixedly connected inside the fixed seat, and a calibration plate fixedly connected to the output end of the electric cylinder.

[0010] Preferably, the fixed seat, electric cylinder and correction plate are symmetrically arranged on the upper surface of the belt conveyor. Beneficial effects

[0011] This utility model provides a printed circuit board placement machine. It has the following advantages:

[0012] (1) The printed circuit board placement machine can synchronously drive the correction plate to apply uniform force to both sides of the circuit board through two sets of symmetrically arranged fixed seats, electric cylinders and correction plates, quickly complete the centering correction of the circuit board, avoid the positioning deviation caused by the position shift during the conveying process of the circuit board, and significantly improve the positioning accuracy and placement consistency of the circuit board.

[0013] (2) The printed circuit board placement machine is equipped with a detachable nozzle. It uses a magnetic ring adsorption and a rod limiting structure to achieve quick installation and removal.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] like Figure 1-4 As shown, this utility model provides a printed circuit board placement machine, including a machine body 1. The machine body 1 is equipped with a belt conveyor 2 and a feeder 3. The top of the machine body 1 is equipped with a first motion mechanism 4. The outer surface of the first motion mechanism 4 is equipped with a second motion mechanism 5. The outer surface of the second motion mechanism 5 is equipped with a third motion mechanism 6. The outer surface of the third motion mechanism 6 is equipped with a placement head 7. The bottom of the placement head 7 is equipped with a mounting tube 8. The bottom of the mounting tube 8 is equipped with a suction nozzle 9. The outer surface of the suction nozzle 9 is fixedly connected with a second magnetic ring 11. The side of the bottom of the mounting tube 8 is equipped with a first magnetic ring 10. The upper surface of the suction nozzle 9 is fixedly connected with a rod 13. The side of the upper surface of the belt conveyor 2 is fixedly connected with a fixed seat 17. The inside of the fixed seat 17 is fixedly connected with an electric cylinder 18. The output end of the electric cylinder 18 is fixedly connected with a correction plate 19.

[0021] Specifically, the bottom of the mounting tube 8 is provided with a through groove 12, and the inner surface of the through groove 12 is adapted to the outer surface of the insertion rod 13.

[0022] Specifically, a sealing sleeve 20 is provided on the top of the nozzle 9, and the outer surface of the sealing sleeve 20 is adapted to the inner surface of the mounting tube 8.

[0023] Specifically, the insert rod 13 has an internal groove 14, and a spring 15 is fixedly connected to the inner surface of the internal groove 14.

[0024] Specifically, a limiting rod 16 is fixedly connected to the end of the spring 15, and the outer surface of the limiting rod 16 is adapted to the inner surface of the internal groove 14.

[0025] Specifically, the fixed seat 17, the electric cylinder 18, and the correction plate 19 are symmetrically arranged on the upper surface of the belt conveyor 2.

[0026] The working principle and beneficial effects of the above embodiments.

[0027] In use, the belt conveyor 2 is used to transport the circuit board, and the feeder 3 is used to supply the electronic components to be mounted. The first motion mechanism 4, the second motion mechanism 5, and the third motion mechanism 6 are a combination of ball screws, linear guides, and drive motors, used to drive the mounting head 7 to move linearly in the X, Y, and Z directions to ensure high-precision component mounting positions. During operation, the conveyor belt of the belt conveyor 2 first moves the circuit board to the two sets of symmetrically arranged correction plates 19, controlling the two electric cylinders 18 to extend synchronously, so that the two correction plates 19 jointly correct the circuit board. Then the conveyor belt continues to transport the circuit board to below the suction nozzle 9. Through the cooperation of the first motion mechanism 4, the second motion mechanism 5, and the third motion mechanism 6, the suction nozzle 9 picks up the electronic components and mounts them onto the circuit board. The suction nozzle 9 is designed to be detachable. When installing the suction nozzle 9, the insertion rod 13 is aligned with the through slot 12 on the mounting tube 8, and the limit rod 16 is in its natural state. With the front end extended, when the limiting rod 16 enters the through groove 12 along with the insert rod 13, after passing the inclined portion at the bottom of the through groove 12, the limiting rod 16 is squeezed into the inner groove 14, and the spring 15 is compressed. When the limiting rod 16 passes through the through groove 12, the elastic force of the spring 15 pushes out the front end of the limiting rod 16. At this time, the extended portion of the limiting rod 16 is on the outer surface of the mounting tube 8. The insert rod 13 and the limiting rod 16 together fix the suction nozzle 9 to the bottom end of the mounting tube 8. The limiting rod 16 serves as a positioning element, while the second magnetic ring 11 is also attracted to the first magnetic ring 10, ensuring that the nozzle 9 is securely installed at the bottom of the mounting tube 8. The top of the nozzle 9 is inserted into the interior of the mounting tube 8, and the sealing sleeve 20 fits against the inner wall of the mounting tube 8, providing a seal. To remove the nozzle 9, press the limiting rod 16 inward to retract it into the inner groove 14, and then pull the nozzle 9 downward. The nozzle 9 is easy to install and remove, and convenient to replace.
