Description

Technical Field

[0001] The utility model relates to the technical field of detection and compensation, in particular to a device for detecting the offset of a pause position of a detection device and for compensating the position. Background Art

[0002] In modern industrial production, precise equipment operation is crucial. Most equipment needs to accurately stop at a specific position during operation to ensure the accuracy of subsequent operations (such as gripping and processing). However, due to factors such as mechanical wear and vibration, equipment can easily shift at the pause position. This can prevent subsequent devices (such as gripping) from operating accurately, significantly reducing production quality and efficiency. Currently, while some detection and compensation devices exist, they suffer from insufficient accuracy and complex structures. Therefore, a more accurate and reliable device for detecting and compensating position is urgently needed. Utility Model Content

[0006] A photoelectric sensor configured to detect a travel difference or offset between the shielding area and the light-transmitting area;

[0007] A PLC controller is used to receive a numerical output signal detected by the photoelectric sensor and determine whether the stop position of the moving disk of the device is offset according to the received numerical output signal;

[0008] The manipulator control unit is used to receive the corresponding position compensation instructions sent by the PLC controller to achieve accurate positioning and error correction, so that the gripping fixture can accurately grip at the pause position of the equipment's moving disk;

[0010] Preferably, the present invention further comprises a support plate, a photoelectric sensor mounting frame is provided on the support plate, and the photoelectric sensor is mounted on the photoelectric sensor mounting frame.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0020] In the description of the present invention, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description.

Therefore, they should not be construed as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0022] Reference Figure 1 、 Figure 2 and Figure 3 As shown, a device for detecting the offset of the pause position of a detection device and compensating the position, the device includes: a detection plate 2 installed on the device motion disk 1, and a plurality of detection through holes 3 arranged at intervals are provided on the detection plate 2, so that a blocking area 4 is formed on the detection plate 2, wherein the detection through hole 3 is a light-transmitting area.

[0023] The photoelectric sensor 5 is used to detect the travel difference or offset between the shielding area 4 and the light-transmitting area.

[0024] The PLC controller 6 is used to receive the numerical output signal detected by the photoelectric sensor 5, and determine whether the pause position of the device motion disk 1 is offset based on the received numerical output signal.

[0025] The manipulator control unit 7 is used to receive the corresponding position compensation instructions sent by the PLC controller 6 to achieve accurate position positioning and error correction, so that the grabbing fixture can accurately grab at the pause position of the equipment moving disk 1.

[0026] The photoelectric sensor 5 and the robot control unit 7 are electrically connected to the PLC controller 6 respectively.

[0027] Specifically, when the single light beam emitted by photoelectric sensor 5 hits the obstruction area 4 of detection plate 2, the numerical signal detected by photoelectric sensor 5 is sent to the PLC controller as the first numerical value. When the single light beam emitted by photoelectric sensor 5 hits the light-transmitting area of ​​detection plate 2, the numerical signal detected by photoelectric sensor 5 is sent to the PLC controller as the second numerical value. Since detection plate 2 has multiple obstruction areas and light-transmitting areas, each numerical signal detected by photoelectric sensor 5 is transmitted to the PLC controller for reception. After receiving these numerical values, the PLC controller records the number of numerical values ​​obtained through the PLC controller program. For example, if the detection plate can detect 17 numerical values, when the PLC controller receives a numerical value of 9, the PLC controller executes compensation data to 0 to the manipulator control unit. If the PLC controller receives a numerical value of 8, the PLC controller sends a leftward offset to the manipulator control unit according to the program settings. If the PLC controller receives a numerical value of 10, the PLC controller sets the rightward offset to the desired position according to the program settings, and so on. In this way, precise grasping position positioning and error correction can be achieved.

[0028] In addition, during installation, the direction of the light beam emitted by the photoelectric sensor 5 needs to be aligned with the detection plate 2, and ensure that the light beam emitted by the photoelectric sensor 5 passes through the detection through-hole 3. At the same time, the photoelectric sensor 5 is powered on and debugged to ensure that it emits the light beam normally. The corresponding control program is written and input into the PLC controller 6, and the compensation direction and data corresponding to different values ​​are set.

[0029] That is to say, in order to enable the photoelectric sensor to detect the blocking area 4 and the light-transmitting area of ​​the detection plate, the utility model also includes a support plate 8, on which a photoelectric sensor mounting bracket 9 is provided, and the photoelectric sensor 5 is mounted on the photoelectric sensor mounting bracket 9, so as to ensure that the light beam emitted by the photoelectric sensor 5 is aligned with the detection plate 2 and passes through the detection through hole 3 at the same time.

[0030] It should be noted that, usually, multiple working units (multiple molds) are used on the equipment moving disk 1. Therefore, the utility model has multiple detection plates 2, and each detection plate 2 is installed corresponding to the position of the working unit. Specifically, each detection plate 2 is installed on the side of the equipment moving disk 1 at intervals along the circumference of the equipment moving disk 1, and each detection plate 2 is provided with a mounting hole 10 connected to the equipment moving disk; during installation, the detection plate is tightened and fixed to the equipment moving disk 1 by passing a fastener through the mounting hole.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
