Description

Technical Field

[0001] The invention relates to the technical field of chip mounters, in particular to a fully automatic high-precision chip mounter. Background Art

[0002] A placement machine is a device that accurately places surface mount components on PCB pads by moving the placement head. It is divided into manual and fully automatic types. The fully automatic placement machine is used to achieve high-speed, high-precision and fully automatic placement of components. It is the most critical and complex equipment in the entire SMT production. The placement machine is the main equipment in the SMT production line. The placement machine has developed from the early low-speed mechanical placement machine to the high-speed optical alignment placement machine, and has developed towards multi-functional, flexible connection modularization.

[0003] The SMT machine in the prior art uses a rubber nozzle to extract components. The rubber nozzle is made of a relatively soft material and will not damage the surface of the material. It is particularly suitable for sucking components with fragile surfaces or components that need protection. The rubber nozzle is suitable for a variety of materials, especially those with rough surfaces or strong toughness, and can ensure the stability and accuracy of suction. Although the life of the rubber nozzle is relatively short, its price is relatively low, and it is easy to replace, and the overall cost is low. The rubber nozzle also has many shortcomings. The rubber nozzle frequently sucks components, and the dust attached to the surface of the component or the dust in the air will erode the rubber nozzle. The rubber nozzle uses the surface that adheres to the dust to contact the component, and there may be a hidden danger of air leakage at the contact position, which makes it impossible for the rubber nozzle to smoothly suck the component. In addition, the rubber nozzle is frequently pressed in the opposite direction by the component, which may cause irreversible shrinkage and deformation, thereby affecting the subsequent placement of components. For this reason, the present invention provides a fully automatic high-precision SMT machine. Summary of the invention

[0038] The lifting device 6 in the prior art drives the riser 4 to rise and fall, thereby driving the mounter 7 to rise and fall as a whole. Figure 6 After the annular rubber nozzle 14 at the bottom descends and contacts the components, the micro air pump 5 in the prior art works, and then the air in the vertical pipe 4 rises and is discharged, and the air flow inside the longitudinal folded tube 10 is discharged upward, so that negative pressure is generated inside the inner cover 17, so that the annular rubber nozzle 14 at the bottom can effectively absorb the components, and the remaining annular rubber nozzles 14 will not inhale air, because the inner cover 17 has only an air guide hole at the bottom side shell, and the bottom annular rubber nozzle 14 frequently takes and places components, and dust may adhere to the surface.

One end of the card plate 33 is inserted into the V-shaped groove formed on the outer wall of the pressing shaft 34 by setting a tip. The other end of the card plate 33 is pressed by the U-shaped spring piece 36. The ring frame 35 is fixed on the folding plate frame 20. The other end of the pressing shaft 34 is fixed on the middle shell of the outer cover 16. The outer side of the ring disk shell 31 is connected to the second cylinder gear 29 by meshing transmission.

[0042] The cleaning section 12 includes a second frame 37 with one end fixed on the longitudinal folded tube 10, a tube 39 supported by the other end of the second frame 37, a tube head 40 connected to one end of the tube 39, and a signal device 38 fixed on the second frame 37. The tube head 40 rotates to wipe the annular rubber nozzle 14 that is contacted in turn.

[0043] The cylinder 39 includes an insulating outer cylinder 42, an insulating inner cylinder 45 movably sleeved inside the insulating outer cylinder 42, an annular spring 41 fixedly sleeved on one end of the insulating inner cylinder 45, a switch metal sheet 44 fixed on the other end of the insulating inner cylinder 45, and two conductive rings 43 fixedly sleeved outside the insulating outer cylinder 42. The signal device 38 is provided with two conductive springs to contact the two conductive rings 43 respectively. Each conductive ring 43 is provided with a metal convex plate, and when the insulating outer cylinder 42 and the insulating inner cylinder 45 rotate in an offset manner, the two metal convex plates are in contact with the switch metal sheet 44 and are energized. The outer end of the annular spring 41 is fixed on the insulating outer cylinder 42, and the insulating outer cylinder 42 is clamped in an annular groove opened on the outer wall of the insulating inner cylinder 45. The outer wall of the insulating outer cylinder 42 is clamped with a circular hole opened on the second frame 37 by opening an annular groove. The outside of the insulating outer cylinder 42 is provided with an external gear ring to mesh with the disc gear fixed at one end of the horizontal long shaft 21 for transmission connection.

[0044] The barrel head 40 includes a tail barrel 49 fixed to the end of the insulating inner barrel 45, a double control barrel 47 arranged at one end of the tail barrel 49, a C-shaped spring 48 connected between the double control barrel 47 and the tail barrel 49, and a cleaning cloth 46 wrapped at one end of the double control barrel 47. A plurality of protrusions are evenly arranged on the tail barrel 49, and the protrusions are stuck in the slide grooves opened on the double control barrel 47.

[0045] In order to prevent the irreversible deformation of the annular rubber nozzle 14 caused by frequent reverse pressure, the present invention adopts multiple annular rubber nozzles 14 to work in turn, so that a single annular rubber nozzle 14 is replaced after working for a period of time, and the resting annular rubber nozzle 14 can have enough time to restore the elastic and full state. The driving principle of the multiple annular rubber nozzles 14 being replaced in turn is: Figure 5 , the chip mounter 7 descends to absorb the components, and then the chip mounter 7 rises to control the components to rise. However, when the chip mounter 7 rises, it will stop when it encounters the return plate 8, so that the replacement mechanism is not triggered. If the annular rubber nozzle 14 needs to be replaced, the chip mounter 7 in the micro air pump 5 can continue to rise, thereby triggering the replacement mechanism, because the bottom end of the return plate 8 will relatively press down the main rack 18, and the main rack 18 moves to drive the centralized control shaft 28 to rotate, and then drives the second cylinder gear 29 through the forward one-way bearing 30, thereby causing the ring disk shell 31 to rotate, and the small The forwarding bar 32 accumulates power and contracts, and the small forwarding bar 32 provides rotation pressure for the pressing shaft 34. After the small forwarding bar 32 accumulates enough power, the clamping state of the pressing shaft 34 is broken, and the pressing shaft 34 will rotate a quarter of a circle, because the four clamping plates 33 are compressed by the U-shaped spring pieces 36 to elastically clamp the pressing shaft 34. During the rotation of the pressing shaft 34, the pressure of the small forwarding bar 32 itself is released. Therefore, the pressing shaft 34 will be re-locked after rotating a quarter of a circle, and the pressing shaft 34 drives the outer cover 16, and then the neck tube 15 drives the annular rubber nozzle 14 to move around. Figure 6The cleaned annular rubber nozzle 14 moves around to the bottom to extract components, while the annular rubber nozzle 14 at the bottom moves around and leaves to rest.

[0046] refer to Figure 6 The process of a single annular rubber nozzle 14 making a circle is divided into four stages, and there will be a stage in which it contacts and docks with the barrel head 40. The barrel head 40 wipes and cleans the annular rubber nozzle 14 and detects the fullness. The principle of wiping and cleaning: during the process of the placement device 7 descending and the return plate 8 separating, the return spring 23 releases the pressure to control the reset and reverse of the centralized control shaft 28, and then reverses the one-way bearing 25 to control the rotation of the first barrel gear 24, and then transmits the horizontal long axis 21 through the side shaft 27. Next, the insulating outer barrel 42 rotates to drive the annular spring 41, causing the insulating inner barrel 45 and the barrel head 40 to rotate synchronously, and the cleaning cloth 46 on the barrel head 40 wipes the docking annular rubber nozzle 14 by rotating.

[0047] Principle of detecting the fullness of the annular rubber nozzle 14: the annular rubber nozzle 14 is in a normal full state. When the cleaning cloth 46 wipes the annular rubber nozzle 14, there is friction resistance, so that the rotation of the insulating outer cylinder 42 causes the annular clockwork 41 to contract, thereby controlling the rotation of the insulating inner cylinder 45. The insulating inner cylinder 45 and the insulating outer cylinder 42 rotate relative to each other, so that the two conductive rings 43 are in contact with the switch metal sheet 44 at the same time. The signal device 38 is a combination of a battery and a signal transmitter in the prior art. When the battery is powered on, the signal transmitter continuously transmits signals to the host terminal. If there is no friction resistance The reason is that the annular rubber nozzle 14 is over-compressed and cannot be restored. There is no contact or little contact between the annular rubber nozzle 14 and the cleaning cloth 46. The insulating outer cylinder 42 and the insulating inner cylinder 45 are almost in a synchronous rotation state. There is no contact between the conductive ring 43 and the switch metal sheet 44, and no subsequent signal transmission will be caused. In this way, whether the annular rubber nozzle 14 has excessive deformation can be judged by the signal received by the host terminal. If the annular rubber nozzle 14 has irreversible deformation, the technician can replace the new annular rubber nozzle 14 in time.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
