(Summary description)As we all know, the low placement rate of SMT equipment is a problem that many SMT manufacturers will encounter. The so-called placement rate refers to the ratio of the number of devices actually placed to the number of pick-ups within a certain period of time. The main reason for the low placement rate of SMT equipment is the failure of SMT equipment, so how to avoid SMT equipment failure? The following Sanjing will give you a brief introduction:
First of all, when purchasing SMT equipment, it is necessary to consider its placement accuracy and placement speed. In the process of use, how to effectively improve product quality and production efficiency, and reduce production costs, is also a problem worth considering. Whether it is a large or small device, the placement machine is mainly composed of a device storage and transportation device, an XY table, a placement head and a control system. The placement head is the core and key component of the placement machine. The placement head generally has a fixed head and a rotating head. The fixed head is generally arranged with multiple heads (as few as 2 and as many as 8), which can be picked up at the same time or...

As we all know, the low placement rate of SMT equipment is a problem that many SMT manufacturers will encounter. The so-called placement rate refers to the ratio of the number of devices actually placed to the number of pick-ups within a certain period of time. The main reason for the low placement rate of SMT equipment is the failure of SMT equipment, so how to avoid SMT equipment failure? The following Sanjing will give you a brief introduction:

 

First of all, when purchasing SMT equipment, it is necessary to consider its placement accuracy and placement speed. In the process of use, how to effectively improve product quality and production efficiency, and reduce production costs, is also a problem worth considering. Whether it is a large or small device, the placement machine is mainly composed of a device storage and transportation device, an XY table, a placement head and a control system. The placement head is the core and key component of the placement machine. The placement head generally has a fixed head and a rotating head. The fixed head is generally arranged with multiple heads (as few as 2 and as many as 8), which can be picked up at the same time or separately; The rotating head is divided into rotating in the horizontal plane and rotating in the vertical plane.

 

In the entire placement process, the correct setting of the nozzle pickup height, the pickup position and the center of the nozzle corresponding to the feeder position, the main factor affecting the device placement rate is the pickup position (ie, the feeder and the nozzle problem). The appearance of the posture detection status monitoring placement machine just solved this problem. Without causing any damage to the device and the substrate, the device can be stably, completely and correctly absorbed, and quickly and accurately installed on the designated location.

 

 

The following Sanjing respectively introduce the reasons for the problems of the feeder and the suction nozzle:

 

The impact of the feeder is mainly concentrated in the abnormal feeding, which is generally manifested as structural deformation caused by long-term use or improper use, which causes the device to attract deviation, stand up or fail to absorb the device. If it is not regularly checked or repaired and replaced in time, it may be possible Cause a lot of waste of devices. At the same time, regular cleaning and lubrication of the feeder are also essential tasks.

 

The suction nozzle is also an important factor affecting the SMT placement rate. The main reasons for the suction nozzle problem are internal and external. The internal reason is, on the one hand, insufficient vacuum negative pressure, on the other hand, the filter on the placement head and the filter on the suction nozzle become black due to pollution and clogging due to the surrounding environment or the impure air source. Therefore, the filter should be replaced regularly to ensure smooth air flow.

 

On the one hand, the external cause is the pressure relief of the air source circuit, and on the other hand, the suction nozzle is blocked due to adhesive or external environmental dust. Therefore, it is necessary to check the cleanliness of the suction nozzle daily and monitor the pickup of the suction nozzle at any time. The blocked or poorly picked suction nozzles should be cleaned or replaced in time to ensure that the suction nozzles are in good condition.

 

In summary, the SMT placement rate is determined by the SMT equipment, so as long as the SMT equipment is prevented from malfunctioning, the SMT placement rate can naturally be improved.

 

The above is about how to improve the SMT placement rate, I hope it can be helpful to everyone!
