Compared with other processes, the automation of polishing is increasingly urgent. The mainstream automatic grinding scheme mainly adopts passive compliance control, that is, the floating devices, such as springs, cushions and other deformable tools are used on the robot terminal machine to resist the force and achieve the balance of contact force. Such schemes have been widely used in conventional scenarios.

However, for micro, vulnerable and fine special workpieces, such as 3C electronics, medical devices and other scenes with high process requirements, some production lines still have to rely on experienced workers to flexibly handle the workpieces through subjective judgments such as vision and touch. The training cost of workers is high and it is difficult to copy.
Another solution is to use a manipulator with a six dimensional force sensor (or even a vision module) to simultaneously control the position and force control planning of the robot through programming. This scheme can achieve high precision grinding, but the overall equipment cost is high, the debugging is complex, and the adaptability is relatively low.
For the polishing and polishing process of precision parts, TM creatively launched the industry’s first “two-dimensional synchronous precision Soft Force Control system”, providing customers with a precision soft force control polishing and polishing solution with high precision, simple debugging and relatively low cost.

This assembly scheme adopts two precision force control TM-wrpla-f wide platform force control push rods to form a two-dimensional synchronous execution platform, which is equipped with TM self-developed softforce ® 2.0 precision force control technology, processing frequency reaches 4000Hz (i.e. 0.25 MS). Through efficient algorithm processing, it can achieve more flexible and accurate motion control, complete the polishing and polishing process of precision workpiece with better performance, and ensure the precise fitting and precise force control of the curved surface of complex workpiece. The robot only needs to cooperate with the simple frame trajectory movement to realize the precision and flexible polishing and deburring of the inner frame of the mobile phone.

During the grinding process, the two-dimensional synchronous precision force control platform can actively adapt to the change of grinding path, and control the grinding force within the required range in real time, so as to ensure uniform grinding effect on the workpiece surface and improve the product yield. The TM software control platform can also feed back the force position and force time curve changes in the grinding process in real time, realize the visualization of process data, and help customers better improve the grinding process quality.

This solution takes up a small space, can be compatible with robots of major brands, supports machining parts of various sizes and types, is suitable for surface treatment scenarios of high-precision parts with higher force control requirements, complex grinding paths and limited space, and provides customers with more convenient and lower cost automated precision polishing solutions.
