The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1-2, a stitch skew detection mechanism provided by an embodiment of the present utility model is shown, which includes a frame 1 and a detection assembly 2. The frame 1 is provided with at least one detection station which is used for placing a workpiece to be detected. The detection assembly 2 comprises a support 21, a driving mechanism 22, driving plates and detection units, wherein the number of the detection units is equal to that of detection stations, the driving mechanism 22 is connected to the support 21 and used for driving the driving plates to reciprocate along the vertical direction, each detection unit comprises a sliding rail 23, a detection block 24, a trigger rod 25 and a sensor 26, the sensor 26 is a photoelectric switch sensor 26, the sliding rail 23 is arranged on the driving plates along the vertical direction, the detection block 24 is connected on the sliding rail 23 in a sliding manner, the trigger rod 25 is vertically arranged on the detection block 24, and the sensor 26 is fixedly connected on the driving plates and positioned at the top end of the trigger rod 25; one of the detecting blocks 24 is correspondingly disposed above one of the detecting stations, and detecting through holes 241 are formed in the detecting block 24.
The number, position, and shape of the detection through holes 241 on the detection block 24 need to be matched with the number, position, and shape of the pins 3 on the workpiece to be detected. In other words, the detection through hole 241 on the detection block 24 needs to be satisfied, and it cannot pass through the detection through hole 241 when the stitch 3 of the workpiece is bent or inclined, and it can pass through the detection through hole 241 when the degree of verticality of the stitch 3 of the workpiece satisfies the assembly requirement.
When the device is used, a workpiece to be detected is placed in a detection station, then the driving plate vertically moves downwards through the driving mechanism 22, if the verticality of the pins 3 of the workpiece meets the assembly requirement, the pins 3 can smoothly pass through the detection through holes 241 in the downward movement process of the driving plate, and at the moment, no relative displacement in the vertical direction exists between the detection block 24 and the driving plate, so that the trigger rod 25 connected to the detection block 24 cannot be displaced relative to the sensor 26, and the sensor 26 cannot be triggered; if the verticality of the pin 3 of the workpiece does not meet the assembly requirement, the pin 3 cannot smoothly pass through the detection through hole 241 in the downward movement process of the driving plate, but the detection block 24 is propped against the detection block 24, so that the detection block 24 is upwardly displaced relative to the driving plate, and the trigger rod 25 is upwardly displaced relative to the sensor 26, so that the sensor 26 is triggered. Namely, the stitch skew detection mechanism can judge whether the verticality of the relay stitch 3 meets the assembly requirement only by triggering the sensor 26, has a very simple structure, and is convenient and quick to detect.
In addition, in the above arrangement, the slide rail 23 is arranged on the driving plate along the vertical direction, and the detection block 24 is slidably connected on the slide rail 23, so that the accuracy of detecting the verticality of the relay pin 3 is ensured.
As a preferred embodiment, the number of detection stations is two. Correspondingly, the number of the detection units is two. By such arrangement, the detection efficiency can be improved.
Preferably, the rack 1 is provided with a conveying line 11, the conveying line 11 is located below the detection block 24, and a position, opposite to the detection block 24, on the conveying line 11 is a detection station. That is, the utility model can directly detect the workpiece on the conveying line 11, and can convey the detected workpiece through the conveying line 11, thereby improving the detection efficiency.
Preferably, the support 21 is vertically provided with a guide rail 211, and the driving plate is slidably connected to the guide rail 211. By providing the guide rail 211, the reliability of the vertical movement of the driving plate can be ensured. Specifically, the driving mechanism 22 is an air cylinder, the fixed end of the air cylinder is connected with the bracket 21, and the movable end of the air cylinder is connected with the driving plate. Of course, the driving may be performed by a conventional linear driving method such as a linear motor, in addition to the cylinder driving method.
Preferably, both ends of the slide rail 23 are provided with stoppers. By arranging the limiting block on the sliding rail 23, the detection block 24 can be prevented from falling off in the moving process, and the use reliability is ensured.
Preferably, the top of the detection block 24 is provided with a spring 242, and the drive plate has a face for abutting against the spring 242. By providing the spring 242, the detecting block 24 can be reset under the action of gravity and elastic force, so that the reliability in the use process is further ensured. In addition, the spring 242 also has a certain buffering effect, so that the detection block 24 is prevented from directly colliding with the driving plate.
Preferably, the vertical position of the trigger lever 25 is adjustable. Specifically, a vertical bar-shaped hole 251 is formed in the trigger rod 25, and the trigger rod 25 is connected with the detection block 24 by passing through the bar-shaped hole 251 through a bolt. The vertical position is adjustable, so that the stitch skew detection mechanism can be conveniently adapted to stitches 3 with different lengths. For example, the trigger lever 25 may be adjusted downward when the stitch 3 is longer, and the trigger lever 25 may be adjusted upward when the stitch 3 is shorter.
