Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to a sensing mechanism of a PPU manipulator. Background Art

[0002] The PPU manipulator mainly uses a motor to drive the cam to move, thereby realizing a mechanical device that carries objects along a predetermined trajectory at the output end, realizing multiple functions such as material picking, material moving, and transportation. In order to enable the motor to accurately detect the motor origin position during operation, the existing PPU manipulator realizes detection by adding a proximity switch. The defect of this structure is that the position of the proximity switch cannot be adjusted and there is only one, which is inflexible and inconvenient to use. In addition, the accuracy of the proximity switch is not high and cannot meet high-precision requirements. Utility Model Content

[0003] In view of the above-mentioned defects in the prior art, the technical problem to be solved by the present invention is how to make the position of the sensor adjustable so as to facilitate use and improve detection accuracy. The specific technical solution is as follows:

[0004] A sensing mechanism of a PPU manipulator comprises a sensor mounting seat, a first sensor, a second sensor and a sensor fixing plate. The sensor mounting seat is mounted on the side of the fixing plate of the PPU manipulator. The sensor mounting seat is provided with a through position adjustment groove. The first sensor, the second sensor and the sensor fixing plate are respectively provided with mounting holes corresponding to the positions. The first sensor is installed in front of the sensor mounting seat by inserting a fastener into the position adjustment groove and the mounting hole. The second sensor is installed in front of the sensor mounting seat by inserting a fastener into the position adjustment groove and the mounting hole. The relative positions of the first sensor and the second sensor can be movably adjusted by loosening the fastener.

[0005] As a preferred solution of the utility model, the first sensor is located at the top to detect whether the output end of the PPU manipulator returns to the origin position, and the second sensor is located at the bottom to detect whether the output end of the PPU manipulator reaches the limit position.

[0006] As a preferred solution of the present utility model, the first sensor and the second sensor are slot-shaped photoelectric sensors.

[0007] As a preferred solution of the utility model, a slide groove is provided in front of the sensor mounting seat, the first sensor and the second sensor are slidably mounted in the slide groove respectively, and the position adjustment groove is arranged in the slide groove.

[0008] As a preferred solution of the utility model, a fixing plate placement groove is provided at the rear of the sensor mounting seat, and the sensor fixing plate is placed in the fixing plate placement groove.

[0009] Beneficial effect: Since the sensor mounting base is provided with a through position adjustment slot, the relative positions of the first sensor and the second sensor can be moved and adjusted by loosening the fasteners, which is convenient for adjusting the position and flexible use. In addition, the use of two sensors, the first sensor and the second sensor, facilitates the resetting of the PPU manipulator. The first sensor and the second sensor are slot-shaped photoelectric sensors, which improve the detection accuracy and meet actual use needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings:

[0015] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the positions or elements referred to must have specific directions, be constructed and operated in specific directions. Therefore, they cannot be understood as limitations on the present invention.

[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0017] like Figure 1-4As shown, a sensing mechanism of a PPU manipulator comprises a sensor mounting seat 1, a first sensor 2, a second sensor 3 and a sensor fixing plate 4. The sensor mounting seat 1 is mounted on the side of the fixing plate of the PPU manipulator. The sensor mounting seat 1 is provided with a through position adjustment slot 5. The cross-sectional shape of the position adjustment slot 5 is a long slot. The first sensor 2, the second sensor 3 and the sensor fixing plate 4 are respectively provided with mounting holes corresponding to the positions. The mounting holes of the first sensor 2 and the second sensor 3 are through holes. The mounting holes of the sensor fixing plate 4 are screw holes.

The second sensor 3 is inserted into the position adjustment groove and the mounting hole by a fastener to be installed in front of the sensor mounting base 1. The fastener is a screw. The fastener can be loosened to adjust the relative position of the first sensor 2 and the second sensor 3 on the position adjustment groove 5. When the position is determined, the screw is tightened again. In this embodiment, there are two position adjustment grooves 5, and there are two sensor fixing plates 4 corresponding to the number of the first sensor 2 and the second sensor 3.
