Description

Technical Field

[0001] The utility model relates to the field of position detection, and in particular to a position detection component for a mobile device. Background Art

[0002] The stamping line includes a variety of moving devices, such as loading trolleys, cleaning machines, oiling machines, etc. In order to ensure that the automated moving device can stay in the correct position, a position detection device is provided to detect the position of the moving equipment to ensure that the automated moving device and the stamping line can work normally; among these position detection components, the proximity switch is a commonly used sensor. The proximity switch uses the principle of electromagnetic induction for detection and does not require mechanical contact or any pressure to operate the switch.

[0003] The moving device of the stamping line moves back and forth between the working position and the offline position. When it stays at the working position, the automated moving device performs cleaning, oiling, loading and other tasks. When it stays at the offline position, it is in a standby state. In the prior art, detection protons are arranged near the working position and the offline position, and the detection protons are arranged on one side of the moving path of the automated moving device. Two proximity switches are arranged on the automated moving device. When moving to the working position, the proximity switch in front along the moving direction first senses the detection protons at the working position, and the proximity switch sends a corresponding signal to the control system, and the control system controls the automated moving device to brake. After moving for a preset time, the control system issues work instructions such as loading, unloading, cleaning or oiling. When moving to the offline position, the proximity switch in front along the moving direction first senses the detection protons at the offline position, and the proximity switch sends a corresponding signal to the control system, and the control system controls the automated moving device to brake.

[0004] In the prior art, a group of corresponding detection protons and proximity switches are respectively arranged at the working position and the offline position, and when moving to the working position, the control system issues a work instruction after a set time. On the one hand, the set time is set to be short, and it is difficult to ensure that the mobile device is in a stopped state when the control system issues the instruction, which affects the smooth progress of the next step of work, thereby causing the entire stamping line to be unable to produce normally, greatly affecting the production efficiency. On the other hand, if the set time is too long, it will cause the mobile device to have a working waiting time, affecting the production efficiency. Utility Model Content

[0011] Furthermore, the mounting bracket is movably arranged in a C-shaped guide rail by means of T-shaped bolts, and the C-shaped guide rail can be arranged on a mobile device.

[0012] Furthermore, the lower part of the proton detector is provided with an elevated portion, and the elevated portion is arranged on the ground.

[0013] The utility model can correspondingly raise the heights of the brake proximity switch and the limit proximity switch by arranging the heightening part, thereby preventing misjudgment caused by magnetic objects on the ground.

[0029] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0030] like Figure 1 and Figure 2 As shown, this specific embodiment provides a mobile device position detection component, including a proximity switch group and a detection proton 1, the proximity switch group includes a braking proximity switch 2 and a limit proximity switch 3, the braking proximity switch 2 and the limit proximity switch 3 can be set on the mobile device 4; the distance between the braking proximity switch 2 and the limit proximity switch 3 is the braking distance of the corresponding mobile device 4, and the length of the detection proton 1 is not less than the braking distance of the corresponding mobile device 4; it also includes a prompt member, the prompt member, the braking proximity switch 2, and the limit proximity switch 3 can all be electrically connected to the control system of the stamping line.

[0031] This specific embodiment provides a braking proximity switch 2 and a limit proximity switch 3. On the one hand, the reliability of the mobile device 4 can be improved by performing two detections compared to one proximity switch. At the same time, the length of the detection proton 1 and the distance between the braking proximity switch 2 and the limit proximity switch 3 are set according to the braking distance. This can ensure that the braking of the mobile device 4 ends when the limit proximity switch 3 senses the detection proton 1, greatly eliminate the influence of braking on position determination, and ensure that the mobile device 4 is in a stopped state at a reasonable position when the control system issues normal working instructions, thereby greatly improving the accuracy of position detection.

[0032] Preferably, the length of the detection proton 1 is d1, and the theoretical braking distance of the corresponding mobile device 4 is d2, d2<d1<d2+50mm. Considering that the braking module of the mobile device 4 wears over time and causes changes in the braking distance, d1 is set between d2 and d2+50mm, which can ensure that after the braking distance is extended, the detection proton 1 can always be sensed by the braking proximity switch 2 during the braking process, avoiding the phenomenon that the braking proximity switch 2 and the limit proximity switch 3 do not generate any signal due to the inability to sense the detection proton 1.

[0033] like Figure 3 As shown, preferably, in this specific embodiment, the brake proximity switch 2 and the limit proximity switch 3 both include a proximity switch body 8 and a mounting bracket 5 connected by bolts, the mounting bracket 5 is used to connect with the mobile device 4, and the mounting bracket 5 is movably arranged in a C-shaped guide rail 6 through a T-bolt 7, and the C-shaped guide rail 6 can be arranged on the mobile device 4; in this specific embodiment, the brake proximity switch 2 and the limit proximity switch 3 are movably installed, considering that the brake module of the mobile device 4 wears over time and causes changes in the actual braking distance, and then, the positions of the brake proximity switch 2 and the limit proximity switch 3 are set to be adjustable, which can be adjusted according to The actual braking distance adjusts the distance between the braking proximity switch 2 and the limit proximity switch 3 to further improve the accuracy of position detection. Therefore, it is necessary to regularly check the braking distance of the mobile device 4 and adjust the distance between the braking proximity switch 2 and the limit proximity switch 3; the proximity switch body 8 is a normally closed proximity switch. If a normally open proximity switch is used, the signal sending is stopped when a proton is sensed. If the normally open proximity switch fails, it will stop sending signals. The control system will issue a work instruction, causing an accident. If a normally closed proximity switch is used, no signal will be generated when a fault occurs, and the control system will not issue a corresponding instruction, so the safety is relatively high.

[0034] In order to avoid signal interference caused by magnetic objects on the ground, in the present specific embodiment, a raised portion 9 is provided at the lower part of the detection proton 1, and the raised portion 9 is set on the ground by bolts. By setting the raised portion 9, the height of the brake proximity switch 2 and the limit proximity switch 3 can be increased accordingly to prevent misjudgment caused by magnetic objects on the ground.

[0035] like Figure 1 As shown, since the mobile device 4 moves back and forth, in order to ensure that both positions can be judged reliably and accurately, two groups of proximity switch groups are provided and are mirrored, that is, the limit proximity switches 3 of the two groups of proximity switch groups are close to each other, and two detection protons 1 are provided, and the detection protons 1 are respectively arranged at the working position and the offline position of the mobile device 4.

[0036] This specific embodiment also includes a protective cover, which can cover the proximity switch group inside, and the protective cover can be connected to the mobile device 4; the prompt part includes an audible and visual alarm, which can be electrically connected to the stamping line control system, and the prompt part also includes a display screen, which can be electrically connected to the stamping line control system and can intuitively display which proximity switch is faulty.

[0037] The working process of the position detection component of the actuator is as follows:

[0038] When the mobile device 4 moves toward the working position, along the direction of movement toward the working position, the proximity switch group arranged in front can sense the detection proton 1 at the working position. First, the braking proximity switch 2 of this proximity switch group senses the detection proton 1 and sends a signal, and the control system controls the mobile device 4 to brake and decelerate. After moving the braking distance, the mobile device 4 stops. At this time, the limit proximity switch 3 senses the detection proton 1 and sends a signal. After receiving the signal from the limit proximity switch 3, the control system issues a corresponding instruction; when the mobile device 4 moves to the offline position, along the direction of movement toward the offline position, the proximity switch group arranged in front can sense the detection proton 1 at the offline position, and the detection process is the same as when moving to the working position, and will not be repeated.

[0039] When the limit proximity switch 3 can send a signal but the brake proximity switch 2 cannot send a signal, it means that the brake proximity switch 2 has a fault. At this time, the mobile device 4 must be stopped urgently to prevent the mobile device 4 from moving too far and causing a collision, and a prompt is issued through the sound and light alarm, and the display screen shows that the corresponding brake proximity switch 2 has a fault; when the brake proximity switch 2 can send a signal but the limit proximity switch 3 cannot send a signal, it means that the limit proximity switch 3 has a fault. The control system issues a prompt through the sound and light alarm, and the display screen shows that the corresponding limit proximity switch 3 has a fault.

[0040] From the above specific implementations, it can be seen that the utility model has the following beneficial effects:

[0041] 1. By setting the brake proximity switch 2 and the limit proximity switch 3, on the one hand, the reliability of the mobile device 4 can be improved by performing two detections compared with one proximity switch. At the same time, the length of the detection proton 1 and the distance between the brake proximity switch 2 and the limit proximity switch 3 are set according to the theoretical braking distance to ensure that the mobile device 4 is just in a stopped state when the control system issues a normal working instruction, which can greatly eliminate the influence of braking on the timing of the control system issuing the next working instruction;

[0042] 2. By movably installing the brake proximity switch 2 and the limit proximity switch 3, the distance between the brake proximity switch 2 and the limit proximity switch 3 can be adjusted according to the actual braking distance, thereby further improving the accuracy of position detection;

[0043] 3. By providing the heightening portion 9, the height of the brake proximity switch 2 and the limit proximity switch 3 can be correspondingly raised to prevent misjudgment caused by magnetic objects on the ground;

[0044] 4. By providing two groups of proximity switch groups, it is possible to accurately and reliably determine whether the mobile device 4 is in the offline position and the working position.
