Description

Technical Field

[0001] This invention belongs to the field of displacement sensor manufacturing technology, specifically relating to an automated multi-bending forming device for displacement sensor brushes. Background Technology

[0002] Displacement sensors include linear displacement sensors and angular displacement sensors. The brush is the signal detection component of most contact displacement sensors. Generally, the brush slides in contact with the working strip on the resistive element to detect changes in electrical signals. These changes in electrical signals are transmitted to the processor, where they are processed and calculated to obtain the linear or angular displacement, thus achieving the purpose of linear or angular displacement detection.

[0003] like Figure 1 As shown, a typical displacement sensor brush includes a spring 1 and brush filaments 4 welded together, and multiple ( Figure 1 There are two brush filaments (or more) in the brush filaments. One end is welded to the spring 1, and the other end is suspended. The spring 1 has two mounting holes 2. Near the suspended end, the brush filament 4 has an end "V"-shaped bend 3, and near the spring 1, it has a root "V"-shaped bend 5. The end "V"-shaped bend 3 facilitates reliable contact with the resistive working strip (or encoder) of the displacement sensor without damaging the cured resistive paste on the working strip. The root "V"-shaped bend 5 provides a larger elastic range of motion for the end "V"-shaped bend 3, ensuring reliable contact between the brush filament 4 and the resistive working strip (or encoder) while extending its service life. The above-mentioned typical displacement sensor brushes are especially used in linear displacement sensors.

[0004] The performance of the aforementioned displacement sensor brush directly affects the accuracy, lifespan, and reliability of the displacement sensor. During brush production, a crucial issue is how to achieve high-precision machining of the end "V"-shaped bend 3 and the root "V"-shaped bend 5 of the brush bristles 4. Traditional machining methods typically employ simple fixtures or tooling, with workers manually bending the bristles. This method has the following drawbacks: because manual operation cannot guarantee that the angle, force, and position of each bend are exactly the same, the bending position and angle of the end "V"-shaped bend 3 and the root "V"-shaped bend 5 are difficult to control precisely. Therefore, the product's quality consistency and stability are not ideal. When the brush is applied to a displacement sensor, it is prone to problems such as high signal noise and short lifespan. The sensor quality lacks stability, resulting in low yield, inconsistent performance, and an inability to effectively control and standardize quality. Furthermore, manual operation requires secondary bending and shaping, necessitating the movement of the semi-finished product, further reducing product quality and resulting in low automation and low production efficiency.

[0029] Then, the visual sensor 36 visually scans the end "V" shaped bending part 3, and transmits the profile image information obtained by scanning to the controller, and the controller compares it according to the preset data, judges whether the end "V" shaped bending part 3 is qualified or not, if qualified, continue to the next step, otherwise alarm the staff to handle; then the controller controls the linear electric cylinder 39 to continue to run, and its moving seat drives the mounting plate 38, elbow clamp 37, pressing plate 33, positioning plate 35 and multiple workpieces to move synchronously to the position of the second bending forming device, until the second proximity sensor 27 detects the signal and transmits it to the controller, and the controller receives the signal and judges that the workpiece is moved to the position, controls the linear electric cylinder 39 to stop running, at this time the multiple workpieces are just beside the rotating shaft 25, as shown in Figure 10 As shown; then the controller controls the forming telescopic cylinder 26 to run, and its telescopic rod drives the moving seat 24, motor 23 and rotating shaft 25 to move synchronously, in this process, the distance sensor 44 checks the corresponding distance information through the sensor reflection plate 42 and transmits it to the controller, and the controller compares the distance information with the preset threshold value, and controls the forming telescopic cylinder 26 to stop running when they are the same, at this time the middle segment of the rotating shaft 25 is just below the root of the brush wire body 40 close to the multiple workpieces, as shown in Figure 11 As shown; then the controller controls the motor 23 to run, and its shaft rotation drives the rotating shaft 25 to rotate synchronously, and the rotating shaft 25 drives the brush wire body 40 of the multiple workpieces to rotate around the edge of the pressing plate 33, and thus realizes the purpose of bending forming, until the brush wire body 40 is bent in place, the controller controls the motor 23 to stop running and keep for a certain time, as shown in Figure 12 As shown; then the controller controls the motor 23 to run in reverse, and its shaft reverse rotation drives the rotating shaft 25 to rotate reversely and reset synchronously, and then the controller controls the forming telescopic cylinder 26 to run reversely, and its telescopic rod drives the moving seat 24, motor 23 and rotating shaft 25 to move reversely and reset synchronously, completing the second bending forming processing, and the processed workpiece is as shown in Figure 1 As shown, the root of the brush wire body 40 is processed with a root "V" shaped bending part 5, and the brush wire body 40 becomes the brush wire 4 of the electric brush.

After receiving the signal, the controller determines that the workpieces have moved in place and controls the linear electric cylinder 39 to stop running. At this time, the multiple workpieces are just below the pressure sensor 21. Then the controller controls the detection telescopic cylinder 19 to run. Its telescopic rod drives the pressure sensor 21 to move downward, applies a set pressure to the brush wire 4 and maintains it for a certain period of time. Then it controls the detection telescopic cylinder 19 to run in the reverse direction. Its telescopic rod drives the pressure sensor 21 to move upward to reset. Then, it checks whether the brush wire 4 has been restored through the vision sensor 36. If it has, it is judged as qualified; otherwise, it is unqualified.
