[0002] The brake caliper is a key component in the electronic parking brake system, which is used to clamp the brake disc to achieve the braking function. It is usually driven by a motor and converts the motor's rotational motion into linear motion through a transmission mechanism. The piston actuator is a part of the caliper, which is responsible for pushing the friction plate to press the brake disc. The piston actuator can be regarded as a core actuator of the brake caliper. The two together constitute the mechanical part of the brake system. When the piston actuator is installed into the caliper, it needs to be assembled and connected with some mechanical components, including O-rings, bearings, and gaskets.

After the reset, the second conveying cavity 115 is in the position of the material transfer column 111, at this time, the material moving column 111 moves downward again under the action of the second cylinder 118 and is inserted into the second conveying cavity 115. At this time, the rotating downward pressing cylinder is started, driving the retaining ring plate 112 to rotate and press down, so that the opening of the retaining ring plate 112 is stuck on the material moving column 111. When the material moving column 111 is reset, the O-ring on the material moving column 111 will be blocked by the retaining ring plate 112 and fall into the second conveying cavity 115, and lubricate in the second conveying cavity 115. Then, the telescopic cylinder 204 drives the material taking joint 214 to move to the top of the second conveying cavity 115, and the sliding cylinder 210 is driven to drive the material taking. The joint 214 moves downward and is inserted into the second conveying cavity 115, so that the oiled O-ring is set on the material-collecting joint 214. Then, the two pushing components alternately push the gasket, the bearing, and the gasket to the upper end surface of the material-collecting platform 309. At this time, the telescopic cylinder 204 drives the material-collecting joint 214 to move to the top of the material-collecting platform 309. The sliding cylinder 210 drives and drives the material-collecting joint 214 to move downward and insert through the material-collecting hole 311 and the material-collecting platform 309, and abuts against the contraction end of the displacement sensor 310, pressing the contraction end downward. The larger the contraction distance, the bearing is taken, and the smaller the contraction distance, the gasket is taken, and the process repeats in sequence. The rings are used to pick up material gaskets, bearings, and gaskets respectively, so that there are four pieces of material on the picking joint 214 from top to bottom, namely, O-rings, gaskets, bearings, and gaskets. After the picking is completed, the telescopic cylinder 204 drives the picking joint 214 to move above the fixed tooling 4. At this time, the downward pressure cylinder 209 is started, thereby driving the circular plate 211 to slide downward, and the three guide columns 212 slide downward, and the picking joint 214 is surrounded by the three guide columns 212, and the lower pressure plate 213 at the bottom slides downward along the picking joint 214, and the O-rings, gaskets, bearings, and gaskets on the picking joint 214 are all pressed downward and installed on the piston actuator to form a connection.
