Description

Technical Field

[0001] This invention belongs to the field of pick and place machine technology, and particularly relates to a pick and place machine feeder head device with a cleaning function. Background Technology

[0002] Cold solder joints are a common type of circuit fault, occurring during the production process and caused by improper manufacturing techniques. This results in an unstable state where the circuit connection is intermittent. Causes include improper cleaning of the solder joint surface, excessively high or low soldering iron tip temperature, or misalignment between the PCB pads and component pads. A pick-and-place machine is a device that uses a moving placement head to accurately place surface mount components onto PCB pads.

[0003] Currently, when pick-and-place machines mount components onto PCBs, debris and dirt from around the PCB can easily fall into the mounting area, leading to subsequent cold solder joints. However, since there are many components mounted on the PCB, using a uniform cleaning method, such as blowing, suction, or sweeping, can easily cause mounted components to fall off, which increases the difficulty of local cleaning before mounting individual components. Summary of the Invention

[0004] The purpose of this invention is to solve the problems that PCB boards are prone to falling debris and dirt before mounting, and that overall cleaning of the PCB board can easily cause mounted components to fall off, resulting in difficult local cleaning and a high incidence of cold solder joints. Therefore, this invention proposes a chip mounter feeder head device with a cleaning function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a chip mounter feeder head device with cleaning function, comprising a fixed rod, a fixed frame, a first rotating mechanism and a second rotating mechanism, wherein the fixed frame is fixedly installed on the end of the fixed rod, a sliding mechanism is provided on one side of the fixed frame, the first rotating mechanism and the second rotating mechanism are respectively installed on opposite sides of the fixed frame, and the second rotating mechanism is fixedly installed on the sliding mechanism;

[0006] The first rotating mechanism includes a first motor and a first turntable. The first motor is fixedly connected to the fixed frame, and the first turntable is fixedly mounted on the first motor. The first turntable is provided with a plurality of suction cups.

[0007] The second rotating mechanism includes a second motor and a second turntable. The second motor is fixedly connected to the sliding mechanism, and the second turntable is fixedly mounted on the second motor. A cleaning mechanism is provided on the second turntable.

[0008] As a further description of the above technical solution:

[0009] The sliding mechanism includes a slide rail and a cylinder. Both the slide rail and the cylinder are fixedly connected to the fixed frame. The second turntable is fixedly installed on the cylinder, and the first motor is slidably installed on the slide rail.

[0010] As a further description of the above technical solution:

[0011] A flange seat is connected between the first turntable and the fixed frame. The flange seat is sleeved on the first motor, and the first turntable rotates around the flange seat.

[0012] As a further description of the above technical solution:

[0013] A flange seat is connected between the second turntable and the sliding mechanism. The flange seat is fitted onto the second motor, and the second turntable rotates around the flange seat.

[0014] As a further description of the above technical solution:

[0015] Multiple suction cups are fixedly connected to the outer wall of the first turntable, and the multiple suction cups are arranged in a ring array along the axis of the first turntable.

[0016] As a further description of the above technical solution:

[0017] The cleaning mechanism includes a cleaning brush and a suction nozzle, which are fixedly connected to the outer wall of the second turntable.

[0018] As a further description of the above technical solution:

[0019] The cleaning brush includes a handle and a brush head. A third motor is provided at the end of the handle, and the brush head is mounted on the third motor.

[0020] As a further description of the above technical solution:

[0021] The first turntable and the second turntable have the same radius, and the axis of the first turntable and the axis of the second turntable coincide.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0023] 1. In this invention, the dual-rotor structure design enables the first and second rotating mechanisms on the machine head to operate synchronously, without interfering with other components inside the pick-and-place machine. Driven by the sliding mechanism, the cleaning mechanism first contacts the pads on the PCB board for cleaning, thus avoiding interference with the placed components. The local cleaning operation is simple and convenient.

[0024] In this invention, the switching between the cleaning brush and the suction nozzle is achieved by rotating the second turntable, and the third motor drives the brush head to rotate to perform deep cleaning of the PCB board surface, so that the solder pads of the PCB board are free of debris and dirt before the components are mounted, ensuring that debris and dirt will not cause cold solder joints, and greatly reducing the occurrence rate of cold solder joints.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see Figure 1-4 The present invention provides a technical solution: a chip mounter feeder head device with cleaning function, comprising a fixed rod 1, a fixed frame 2, a first rotating mechanism 3 and a second rotating mechanism 4, wherein the fixed frame 2 is fixedly installed on the end of the fixed rod 1, and a sliding mechanism 5 is provided on one side of the fixed frame 2; the first rotating mechanism 3 and the second rotating mechanism 4 are respectively installed on opposite sides of the fixed frame 2, and the second rotating mechanism 4 is fixedly installed on the sliding mechanism 5;

[0033] The first rotating mechanism 3 includes a first motor 31 and a first turntable 32. The first motor 31 is fixedly connected to the fixed frame 2, and the first turntable 32 is fixedly mounted on the first motor 31. A plurality of suction cups 6 are provided on the first turntable 32.

[0034] The second rotating mechanism 4 includes a second motor 41 and a second turntable 42. The second motor 41 is fixedly connected to the sliding mechanism 5, and the second turntable 42 is fixedly mounted on the second motor 41. A cleaning mechanism 7 is provided on the second turntable 42.

[0035] The sliding mechanism 5 includes a slide rail 51 and a cylinder 52. Both the slide rail 51 and the cylinder 52 are fixedly connected to the fixed frame 2. The second turntable 42 is fixedly installed on the cylinder 52. The first motor 31 is slidably installed on the slide rail 51. The cylinder 52 extends and retracts and acts on the second turntable 42, thereby driving the second turntable 42 and the second motor 41 to slide on the slide rail 51. Before the components are mounted, the cleaning mechanism 7 extends into the PCB board surface for cleaning, thereby avoiding interference between the components on the suction cup 6 and the mounted components.

[0036] A flange seat 8 is connected between the first turntable 32 and the fixed frame 2. The flange seat 8 is sleeved on the first motor 31. The first turntable 32 rotates around the flange seat 8. The flange seat 8 supports the first turntable 32 and ensures the stability of the structure of the first turntable 32.

[0037] A flange seat 8 is connected between the second turntable 42 and the sliding mechanism 5. The flange seat 8 is sleeved on the second motor 41. The second turntable 42 rotates around the flange seat 8. The flange seat 8 supports the second turntable 42 and ensures the stability of the structure of the second turntable 42.

[0038] Multiple suction cups 6 are fixedly connected to the outer wall of the first turntable 32. The multiple suction cups 6 are arranged in a ring array along the axis of the first turntable 32, which can adsorb multiple components at one time and ensure that the components do not interfere with each other, thus improving the placement efficiency and ensuring that the components are not damaged during the placement process.

[0039] The cleaning mechanism 7 includes a cleaning brush 71 and a suction nozzle 72. The cleaning brush 71 and the suction nozzle 72 are fixedly connected to the outer wall of the second turntable 42. The cleaning brush 71 is responsible for brushing up the dirt adsorbed on the PCB board, and the suction nozzle 72 removes the dirt. The cleaning effect is good, thereby avoiding the accumulation of dirt and avoiding the occurrence of cold solder joints.

[0040] The cleaning brush 71 includes a handle 711 and a brush head 712. A third motor 9 is provided at the end of the handle 711. The brush head 712 is mounted on the third motor 9. The third motor 9 rotates and drives the brush head 712 to rotate. The brush head 712 cleans the dirt on the surface of the PCB board.

[0041] The first turntable 32 and the second turntable 42 have the same radius, and the axis of the first turntable 32 and the axis of the second turntable 42 coincide, ensuring that there is no interference between the second turntable 42 and the PCB board when the machine head is working.

[0042] Working principle: First, the upper end of the fixing rod 1 is installed on the pick-and-place machine. The pick-and-place machine moves the machine head to the component carrier tape. The suction cup 6 picks up the components on the carrier tape. The first motor 31 controls the first turntable 32 to rotate. The turntable rotates along the flange seat 8. The suction cup 6 on the first turntable 32 successively picks up multiple components on the carrier tape. Next, the pick-and-place machine moves the machine head above the PCB board where the components to be placed are located. The cylinder 52 extends and pushes the flange seat 8, the second motor 41, and the second turntable 42 to slide along the slide rail 51. The cleaning brush 71 on the second turntable 42 is attached to the surface of the solder pad. The third motor 9 on the PCB rotates, driving the brush head 712 to rotate and clean the surface dirt of the PCB. After the cleaning brush 71 has finished cleaning, the second motor 41 controls the second turntable 42 to rotate. The second turntable 42 rotates along the flange seat 8, and the suction nozzle 72 is aligned with the position of the solder pad that has just been cleaned to remove the dirt brushed off the solder pad. Then, the cylinder 52 retracts and pulls the flange seat 8, the second motor 41 and the second turntable 42 to slide along the slide rail 51. Finally, the pick-and-place machine controls the machine head to descend as a whole and mounts the components on the suction cup 6 onto the PCB.
