Application of the OMRON NJ controller in the secondary battery pack combination machine

Summary: this paper introduces the Omron NJ controller OMRON application OMRON in these secondary battery pack combination machine, about secondary battery pack combination in three difficulties in the application and put forward effective solutions and gain NJ customers NJ a NJ high degree of recognition.

Key words: Omron  NJ NJ controller  NJ Secondary battery NJ combination machine

1 Introduction

Secondary battery also known as the rechargeable battery, means that the battery can be activated and continue to use the battery after the battery discharge. Due to the lack of energy, secondary battery industry has been developing fast. Today, the secondary battery has become one of the key parts of electronic devices, especially in the notebook computer, mobile phone and other devices occupy a pivotal position

In recent years, the production of the secondary battery is being transferred to China, the rapid growth of output. In the actual production process, the secondary battery of wrapper technology will affect the quality and production costs. To this end, OMRON developed a set of NJ OMRON as the core of the <a href="/searchfanan.html?search=system&select=7">system to meet the market

2 device structure and function

2.1 components

Secondary battery pack distribution group as shown in Figure 1, device mainly consists of six parts, namely separators section, a station to take part, including parts, two-position see section, three-position delivery and distribution group output

2.2 part function introduction

1. diaphragm part: used to transport encapsulated ACM films used to plate.

2. a station to take part: to transport rolls need packages sealing plate to themain road (the electrode axis), as shown in Figure 2.

3. part of the package plate: the plate of the plate sent to seal. The concrete operation process is: ACM film through the separator to the transmission of the motor to the mold axis, the knife shaft to the film to the cutting and folding of the central line of the plate, the plate of the plate into the end of the film on both sides of the side sealing. As shown in figure 3.

4. send two work pieces parts: used to transport the negative plate of the package is required, and sealed package of positive plates stacked.

5. three-position see section: after waiting for a set of plates group, used to transport the positive plate superimposed on the plate group, superimposed by the combination the motor is sent out.

3 system hardware solutions

3.1 system hardware structure (see Figure 4)

3.2 system hardware configuration (see table 1)

4 control system difficulty and solve

4.1 ACM length required any modifications

In practice, in order to facilitate coating plates are more flexible, ACM film length must be modified arbitrarily.

NJ axis because of the annular modes after setting, the maximum and minimum values cannot be modified through the program, in order to achieve long film modified requirements, membrane axis can only linear mode.

4.2 pressure line must not have stretch marks

Knife pressure film speed and film speed are not synchronized, it is easy to cause stretch marks with the location in the middle of the film. Fixed-length ACM pressure and cutting in the middle of the film, cutter rotation speed must be ACM film feeding speed synchronization, line step on no stretch marks.

4.3 feed package available on cycle

For the battery internal plate into the material, you must be able to achieve the number of packages to seal a package, and then continue to cycle function. Package sealing assembly machine are basically using external photoelectric signal as stop package and the package again when the trigger point, but the speed and error and start again when the first bag will folio midline appears uneven phenomenon. In this regard, the NJ controller uses a more precise control algorithm to ensure that no error occurs.

5 system control algorithm

The key is to press the line speed of the cutter shaft and the axis of the shaft. This is to use the electronic cam function, but the electronic cam table changes with the length of the bag, so we must calculate the electronic cam according to the length of the bag.

Figure 5~8 interception of the whole system of the part of the control algorithm. The CamGear in Program1 is used to calculate the coordinates of the electronic cam and the ratio of the electronic gear, and the length of the bag is modified (by modifying the "bag length setting" value) of the touch screen, and the For statement is used to modify the cam table dynamically.

6 conclusion

At present, the whole system is used in the customer site. It is proved that the system can ensure the stable production of no error on the package of the two batteries, and meet the customer's production needs. At controller the controller same time, we also see the OMRON NJ controller in the industry wide application prospects.
