The chip mounter comprises an integrated feeding frame, a material belt driving device, a two-segment type conveyor belt, a suction nozzle changing device and a circuit board supporting and balancing device, wherein the integrated feeding frame is composed of storage bins and corresponding grooves arranged on a frame body, the material belt driving device is composed of a needle bar, the suction nozzle changing device and the circuit board supporting and balancing device are respectively located under a chip mounting working surface, and the number of the storage bins and the number of the corresponding grooves are respectively 40.

Description

technical field [0001] The invention relates to a processing machine for circuit boards of electronic appliances, in particular to a placement machine for mounting circuit boards. Background technique [0002] The placement machine is a relatively modern production and processing device for telecommunication products. With the continuous development of the electronic industry technology, the placement machine has more and more types, the structure is more reasonable and mature, the function is more powerful and perfect, and the performance is more superior. reliable. Nevertheless, things are always developing, and there are always defects and deficiencies of one kind or another in existing placement machines. For example, the relatively mature and widely used placement machine has only one set of conveyor belts, and the circuit board is supported by two narrow belts at the front and rear, and the middle is empty. Although this structure is simple, it can only wait for one l...

Problems solved by technology

For example, the relatively mature and widely used placement machine has only one set of conveyor belts, and the circuit board is supported by two narrow belts at the front and rear, and the middle is empty. Although this structure is simple, it can only wait for one line when working. After the board is out of the board, the next circuit board can enter the board, which wastes a lot of time, and the phenomenon of sinking in the middle of the circuit board may occur, which affects the placement effect; low work efficiency and poor reliability

[0003] In addition, the existing placement machine nozzle replacement device is fixed on one side of the machine and is within the working area of ​​the placement machine, so collisions may occur during the placement programming process; the usual solution is In the software, set this area as a special area for nozzle replacement, not as a working area, but doing so will waste a large area of ​​working area and increase the size of the placement machine

[0004] There is also a feeding device. The feeding devices used in the existing placement machines are all one-to-one, that is to say, each material needs to be installed in a feeding device, and a feeding device corresponds to a driver; This kind of feeding device has a complex structure and relatively high price. Generally speaking, the feeding device accounts for about 30% of the total price of a placement machine;

[0005] And a placement machine often needs to adapt to many different specifications and types of circuit board placement, and the components to be mounted on each circuit board are different. At this time, it is necessary to install the installed feeding device one by one. Replacing it is time-consuming and labor-intensive, and it is particularly troublesome
